Expert Perspective

No matter how much we’d like to leave it in the dust, COVID-19 remains prevalent and potent. Tens of thousands of people still contract COVID per week in the United States. Hundreds die. And those who don’t may still develop long COVID.

Pleas from public health officials for people to get a COVID vaccine or booster shot have been ignored by many people. About 80% of eligible Americans haven’t taken any kind of COVID booster. Meantime, the virus continues to mutate, eroding the efficacy of the vaccine’s past versions.

How to get more people to get the jab? Vaccine hesitancy, said infectious disease specialist William Schaffner, MD, is likely rooted in a lack of trust in authority, whether it’s public health officials or politicians.

Dr. Schaffner, professor of infectious diseases at the Vanderbilt University School of Medicine, Nashville, Tennessee, and former medical director of the National Foundation for Infectious Diseases, recommended five strategies physicians can try when discussing the importance of staying up to date on COVID vaccines with patients.
 

#1: Be Patient With Your Patient

First and foremost, if doctors are feeling reluctance from their patients, they need to know “what they shouldn’t do,” Dr. Schaffner said.

When a patient initially doesn’t want the vaccine, doctors shouldn’t express surprise. “Do not scold or berate or belittle. Do not give the impression the patient is somehow wrong or has failed a test of some sort,” Dr. Schaffner said.

Step back and affirm that they understand what the patient is saying so they feel reassured, even if they don’t agree or it’s based on falsehoods about the vaccine.

He said patients need to feel “the doctor heard them; it’s okay to tell the doctor this.” When you affirm what the patient says, it puts them at ease and provides a smoother road to eventually getting them to say “yes.”

But if there’s still a roadblock, don’t bulldoze them. “You don’t want to punish the patient ... let them know you’ll continue to hear them,” Dr. Schaffner said.
 

#2: Always Acknowledge a Concern

Fear of side effects is great among some patients, even if the risks are low, Dr. Schaffner said. Patients may be hesitant because they’re afraid they’ll become one of the “two or three in a million” who suffer extremely rare side effects from the vaccine, Dr. Schaffner said.

In that case, doctors should acknowledge their concern is valid, he said. Never be dismissive. Ask the patients how they feel about the vaccine, listen to their responses, and let them know “I hear you. This is a new mRNA vaccine…you have concern about that,” Dr. Schaffner said.

Doctors can segue into how there’s little reason to wait for some elusive perfectly risk-free vaccine when they can help themselves right now.

“The adverse events that occur with vaccines occur within 2 months [and are typically mild]. I don’t know of a single vaccine that has genuinely long-term implications,” Dr. Schaffner said. “We should remember that old French philosopher Voltaire. He admonished us: Waiting for perfection is the great enemy of the current good.”
 

#3: Make a Strong Recommendation

Here’s something that may seem obvious: Don’t treat the vaccine as an afterthought. “Survey after survey tells us this ... it has everything to do with the strength of the recommendation,” Dr. Schaffner said.

Doctors typically make strong treatment recommendations such conditions as diabetes or high blood pressure, but “when it comes to vaccines, they’re often rather nonchalant,” he said.

If a patient is eligible for a vaccine, doctors should tell the patient they need to get it — not that you think they should get it. “Doctors have to make a firm recommendation: ‘You’re eligible for a vaccine ... and you need to get it ... you’ll receive it on your way out.’ It then becomes a distinct and strong recommendation,” he said.
 

#4: Appeal to Patients’ Hearts, Not Their Minds

In the opening of Charles Dickens’s novel “Hard Times,” the stern school superintendent, Mr. Gradgrind, scolds his students by beating their brow with the notion that, “Facts alone are wanted in life. Plant nothing else and root out everything else.”

The idea that facts alone can sway a vaccine-resistant patient is wrong. “It often doesn’t happen that way,” Dr. Schaffner said. “I don’t think facts do that. Psychologists tell us, yes, information is important, but it’s rarely sufficient to change behavior.”

Data and studies are foundational to medicine, but the key is to change how a patient feels about the data they’re presented with, not how they think about it. “Don’t attack their brain so much but their heart,” Dr. Schaffner said.

Dr. Schaffner has stressed with his patients that the COVID vaccine has become “the social norm,” suggesting virtually everyone he knows has received it and had no problem.

Once questions have been answered about whether the vaccine works and its various side effects, doctors could remind the patient, “You know, everyone in my office is getting the vaccine, and we’re trying to provide this protection to every patient,” he said.

You’re then delving deeper into their emotions and crossing a barrier that facts alone can’t breach.
 

#5: Make it Personal

Lead by example and personalize the fight against the virus. This allows doctors to act as if they’re building an alliance with their patients by framing the vaccine not as something that only affects them but can also confer benefits to a broader social circle.

Even after using these methods, patients may remain resistant, apprehensive, or even indifferent. In cases like these, Dr. Schaffner said it’s a good idea to let it go for the time being.

Let the patient know they “have access to you and can keep speaking with you about it” in the future, he said. “It takes more time, and you have to be cognizant of the nature of the conversation.”

Everybody is unique, but with trust, patience, and awareness of the patient’s feelings, doctors have a better shot at finding common ground with their patients and convincing them the vaccine is in their best interest, he said.

Welcome to Impact Factor, your weekly dose of commentary on a new medical study. I’m Dr F. Perry Wilson of the Yale School of Medicine.

In the early days of the pandemic, before we really understood what COVID was, two specialties in the hospital had a foreboding sense that something was very strange about this virus. The first was the pulmonologists, who noticed the striking levels of hypoxemia — low oxygen in the blood — and the rapidity with which patients who had previously been stable would crash in the intensive care unit.

The second, and I mark myself among this group, were the nephrologists. The dialysis machines stopped working right. I remember rounding on patients in the hospital who were on dialysis for kidney failure in the setting of severe COVID infection and seeing clots forming on the dialysis filters. Some patients could barely get in a full treatment because the filters would clog so quickly.

We knew it was worse than flu because of the mortality rates, but these oddities made us realize that it was different too — not just a particularly nasty respiratory virus but one that had effects on the body that we hadn’t really seen before.

Has COVID replaced syphilis as the great imitator? At the turn of the 20th century, Sir William Osler was quoted as saying, “He who knows syphilis knows medicine.”

If you have any doubts about the “imitator” analogy, simply use any broad search engine or AI portal and enter “what is the differential diagnosis of primary syphilis, or secondary syphilis, or tertiary syphilis?” A plethora of diseases across many body systems appears.
 

Another Great Pretender?

Did you or do you now have long COVID? How do you know? Do you even know what long COVID is? How would you diagnosis it?

When asked about long COVID, this is what large language model source bard.google.com had to say:

Long COVID, also known as post-COVID conditions or PASC, is a complex condition that can occur in people who have had COVID-19, even if their initial illness was mild or even asymptomatic. It’s characterized by a wide range of symptoms that can last for weeks, months, or even years after the initial infection.

Symptoms of long COVID can include: fatigue, shortness of breath, brain fog (trouble thinking or concentrating), loss of smell or taste, sleep problems, muscle pain, joint pain, headache, dizziness, depression or anxiety, heart palpitations, gastrointestinal problems.

Duh!!! It reads much like a continuation of the symptoms of acute COVID. Bard continued:

The exact cause of long COVID is still unknown, but there are several theories. One possibility is that the virus itself can damage organs and tissues, leading to ongoing symptoms. Another possibility is that the immune system’s response to the virus can continue to cause inflammation even after the virus is gone.

Human intelligence source Wikipedia says this:

Long COVID or long-haul COVID is a group of health problems persisting or developing after an initial COVID-19 infection. Symptoms can last weeks, months or years and are often debilitating. The World Health Organization defines long COVID as starting three months after infection, but other definitions put the start of long COVID at four weeks.

Highly varied, including post-exertional malaise (symptoms made worse with effort), fatigue, muscle pain, shortness of breath, chest pain, and cognitive dysfunction (brain fog).
 

Acute COVID to Long COVID

The World Health Organization estimates that 36 million people in the European region have developed long COVID in the first 3 years of the pandemic. That›s a lot.

We all know that the common signs and symptoms of acute COVID-19 include fever or chills, a dry cough and shortness of breath, feeling very tired, muscle or body aches, headache, loss of taste or smell, sore throat, congestion, runny nose, nausea, vomiting, and diarrhea. Except for the taste and smell findings, every one of these symptoms or signs could indicate a different virus infection or even some type of allergy. My point is the nonspecificity in this list.

Uncommon signs and symptoms of acute COVID include a flat skin rash covered with small bumps, discolored swollen areas on the fingers and toes (COVID toes), and hives. The skin of hands, wrists, or ankles also can be affected. Blisters, itchiness, rough skin, or pus can be seen.

Severe confusion (delirium) might be the main or only symptom of COVID-19 in older people. This COVID-19 symptom is linked with a high risk for poor outcomes, including death. Pink eye (conjunctivitis) can be a COVID-19 symptom. Other eye problems linked to COVID-19 are light sensitivity, sore eyes, and itchy eyes. Acute myocarditis, tinnitus, vertigo, and hearing loss have been reported. And 1-4 weeks after the onset of COVID-19 infection, a patient may experience de novo reactive synovitis and arthritis of any joints.

So, take your pick. Myriad symptoms, signs, diseases, diagnoses, and organ systems — still present, recurring, just appearing, apparently de novo, or after asymptomatic infection. We have so much still to learn.

What big-time symptoms, signs, and major diseases are not on any of these lists? Obviously, cancer, atherosclerotic cardiovascular diseases, obesity, bone diseases, and competitive infections. But be patient; the lingering effects of direct tissue invasion by the virus as well as a wide range of immunologic reactions may just be getting started. Mitochondrial damage, especially in muscles, is increasingly a pathophysiologic suspect.

Human diseases can be physical or mental; and in COVID, that twain not only meet but mix and mingle freely, and may even merge into psychosoma. Don’t ever forget that. Consider “fatigue.” Who among us, COVID or NOVID, does not experience that from time to time?

Or consider brain fog as a common reported symptom of COVID. What on earth is that actually? How can a person know they have brain fog, or whether they had it and are over it?

We need one or more lab or other diagnostic tests that can objectively confirm the diagnosis of long COVID.
 

Useful Progress?

A recent research paper in Science reported intriguing chemical findings that seemed to point a finger at some form of complement dysregulation as a potential disease marker for long COVID. Unfortunately, some critics have pointed out that this entire study may be invalid or irrelevant because the New York cohort was recruited in 2020, before vaccines were available. The Zurich cohort was recruited up until April 2021, so some may have been vaccinated.

Then this news organization came along in early January 2024 with an article about COVID causing not only more than a million American deaths but also more than 5000 deaths from long COVID. We physicians don’t really know what long COVID even is, but we have to sign death certificates blaming thousands of deaths on it anyway? And rolling back the clock to 2020: Are patients dying from COVID or with COVID, according to death certificates?Now, armed with the knowledge that “documented serious post–COVID-19 conditions include cardiovascular, pulmonary, neurological, renal, endocrine, hematological, and gastrointestinal complications, as well as death,” CDC has published clear and fairly concise instructions on how to address post-acute COVID sequelae on death certificates.

In late January, this news organization painted a hopeful picture by naming four phenotypes of long COVID, suggesting that such divisions might further our understanding, including prognosis, and even therapy for this condition. Among the clinical phenotypes of (1) chronic fatigue–like syndrome, headache, and memory loss; (2) respiratory syndrome (which includes cough and difficulty breathing); (3) chronic pain; and (4) neurosensorial syndrome (which causes an altered sense of taste and smell), overlap is clearly possible but isn›t addressed.

I see these recent developments as needed and useful progress, but we are still left with…not much. So, when you tell me that you do or do not have long COVID, I will say to you, “How do you know?”

I also say: She/he/they who know COVID know medicine.

Human diseases can be physical or mental; and in COVID, that twain not only meet but mix and mingle freely, and may even merge into psychosoma. Don’t ever forget that. Consider “fatigue.” Who among us, COVID or NOVID, does not experience that from time to time?

Or consider brain fog as a common reported symptom of COVID. What on earth is that actually? How can a person know they have brain fog, or whether they had it and are over it?

We need one or more lab or other diagnostic tests that can objectively confirm the diagnosis of long COVID.
 

Useful Progress?

A recent research paper in Science reported intriguing chemical findings that seemed to point a finger at some form of complement dysregulation as a potential disease marker for long COVID. Unfortunately, some critics have pointed out that this entire study may be invalid or irrelevant because the New York cohort was recruited in 2020, before vaccines were available. The Zurich cohort was recruited up until April 2021, so some may have been vaccinated.

Then this news organization came along in early January 2024 with an article about COVID causing not only more than a million American deaths but also more than 5000 deaths from long COVID. We physicians don’t really know what long COVID even is, but we have to sign death certificates blaming thousands of deaths on it anyway? And rolling back the clock to 2020: Are patients dying from COVID or with COVID, according to death certificates?Now, armed with the knowledge that “documented serious post–COVID-19 conditions include cardiovascular, pulmonary, neurological, renal, endocrine, hematological, and gastrointestinal complications, as well as death,” CDC has published clear and fairly concise instructions on how to address post-acute COVID sequelae on death certificates.

In late January, this news organization painted a hopeful picture by naming four phenotypes of long COVID, suggesting that such divisions might further our understanding, including prognosis, and even therapy for this condition. Among the clinical phenotypes of (1) chronic fatigue–like syndrome, headache, and memory loss; (2) respiratory syndrome (which includes cough and difficulty breathing); (3) chronic pain; and (4) neurosensorial syndrome (which causes an altered sense of taste and smell), overlap is clearly possible but isn›t addressed.

I see these recent developments as needed and useful progress, but we are still left with…not much. So, when you tell me that you do or do not have long COVID, I will say to you, “How do you know?”

I also say: She/he/they who know COVID know medicine.

A version of this article first appeared on Medscape.com.

Has COVID replaced syphilis as the great imitator? At the turn of the 20th century, Sir William Osler was quoted as saying, “He who knows syphilis knows medicine.”

If you have any doubts about the “imitator” analogy, simply use any broad search engine or AI portal and enter “what is the differential diagnosis of primary syphilis, or secondary syphilis, or tertiary syphilis?” A plethora of diseases across many body systems appears.
 

Another Great Pretender?

Did you or do you now have long COVID? How do you know? Do you even know what long COVID is? How would you diagnosis it?

When asked about long COVID, this is what large language model source bard.google.com had to say:

Long COVID, also known as post-COVID conditions or PASC, is a complex condition that can occur in people who have had COVID-19, even if their initial illness was mild or even asymptomatic. It’s characterized by a wide range of symptoms that can last for weeks, months, or even years after the initial infection.

Symptoms of long COVID can include: fatigue, shortness of breath, brain fog (trouble thinking or concentrating), loss of smell or taste, sleep problems, muscle pain, joint pain, headache, dizziness, depression or anxiety, heart palpitations, gastrointestinal problems.

Duh!!! It reads much like a continuation of the symptoms of acute COVID. Bard continued:

The exact cause of long COVID is still unknown, but there are several theories. One possibility is that the virus itself can damage organs and tissues, leading to ongoing symptoms. Another possibility is that the immune system’s response to the virus can continue to cause inflammation even after the virus is gone.

Human intelligence source Wikipedia says this:

Long COVID or long-haul COVID is a group of health problems persisting or developing after an initial COVID-19 infection. Symptoms can last weeks, months or years and are often debilitating. The World Health Organization defines long COVID as starting three months after infection, but other definitions put the start of long COVID at four weeks.

Highly varied, including post-exertional malaise (symptoms made worse with effort), fatigue, muscle pain, shortness of breath, chest pain, and cognitive dysfunction (brain fog).
 

Acute COVID to Long COVID

The World Health Organization estimates that 36 million people in the European region have developed long COVID in the first 3 years of the pandemic. That›s a lot.

We all know that the common signs and symptoms of acute COVID-19 include fever or chills, a dry cough and shortness of breath, feeling very tired, muscle or body aches, headache, loss of taste or smell, sore throat, congestion, runny nose, nausea, vomiting, and diarrhea. Except for the taste and smell findings, every one of these symptoms or signs could indicate a different virus infection or even some type of allergy. My point is the nonspecificity in this list.

Uncommon signs and symptoms of acute COVID include a flat skin rash covered with small bumps, discolored swollen areas on the fingers and toes (COVID toes), and hives. The skin of hands, wrists, or ankles also can be affected. Blisters, itchiness, rough skin, or pus can be seen.

Severe confusion (delirium) might be the main or only symptom of COVID-19 in older people. This COVID-19 symptom is linked with a high risk for poor outcomes, including death. Pink eye (conjunctivitis) can be a COVID-19 symptom. Other eye problems linked to COVID-19 are light sensitivity, sore eyes, and itchy eyes. Acute myocarditis, tinnitus, vertigo, and hearing loss have been reported. And 1-4 weeks after the onset of COVID-19 infection, a patient may experience de novo reactive synovitis and arthritis of any joints.

So, take your pick. Myriad symptoms, signs, diseases, diagnoses, and organ systems — still present, recurring, just appearing, apparently de novo, or after asymptomatic infection. We have so much still to learn.

What big-time symptoms, signs, and major diseases are not on any of these lists? Obviously, cancer, atherosclerotic cardiovascular diseases, obesity, bone diseases, and competitive infections. But be patient; the lingering effects of direct tissue invasion by the virus as well as a wide range of immunologic reactions may just be getting started. Mitochondrial damage, especially in muscles, is increasingly a pathophysiologic suspect.

Human diseases can be physical or mental; and in COVID, that twain not only meet but mix and mingle freely, and may even merge into psychosoma. Don’t ever forget that. Consider “fatigue.” Who among us, COVID or NOVID, does not experience that from time to time?

Or consider brain fog as a common reported symptom of COVID. What on earth is that actually? How can a person know they have brain fog, or whether they had it and are over it?

The arrival of GLP-1 receptor agonists has revolutionized treatment options for people with obesity and medical practice.

This news organization recently hosted a panel of experts across specialties — including endocrinology, gastroenterology, and obesity medicine — to discuss these potentially life-changing medications and to answer questions from the audience.

Because of the flood of queries from our audience, we asked our panelists to address some of the questions that didn’t make the recording. Their answers are below.

Beverly Tchang, MD, endocrinologist, Weill Cornell Medicine, New York City

Audience member: Can you initiate glucagon-like peptide-1 agonists (GLP-1 RAs) as a primary drug in a patient with obesity and newly diagnosed type 2 diabetes?

BT: We often prescribe GLP-1 RAs to individuals with type 2 diabetes as a first-line medication. Guidelines from the American Diabetes Association are really emphasizing a patient-centered approach, and metformin may not be the best first-line medication anymore.

Audience member: What should clinicians know about dose titration of GLP-1 RAs in diabetic patients with renal disease, especially those in stages IV and V chronic kidney disease?

BT: GLP-1 RAs do not need to be renally dosed, but I still recommend conferring with the patient’s nephrologist because the glomerular filtration rate might decrease in the setting of dehydration. Because GLP1s suppress the thirst, not just appetite, patients can go all day without drinking water and not feel thirsty.

Michael Camilleri, MD, gastroenterologist, Mayo Clinic, Rochester, Minnesota

Audience member: Should GLP-1 RAs be held for 1 week or 4 weeks prior to surgery to reduce the patient’s risk for aspiration? And is tapering required?

MC: For a patient taking liraglutide, I would hold the drug for 1 week prior to surgery. For patients taking other GLP-1 RAs, including extended exenatide, I advise holding for between 2 and 3 weeks before the procedure. It’s also important to make sure the patient’s diabetes is well-controlled with other medications — not GLP-1 RAs — during this period.

After surgery, you can restart GLP-1 RA therapy once there is recovery of oral food intake and normal bowel function.

Audience member: Is treatment with GLP-1 RAs appropriate for a patient with a family history of colon cancer but an otherwise unremarkable medical and family history?

MC: I have not seen a contraindication to receiving GLP-1 RAs based on a family history of colorectal cancer or other malignancies. An analysis of the French national healthcare insurance system database has suggested 1-3 years use of GLP-1 RAs (exenatide, liraglutide, and dulaglutide) may be linked with increased occurrence of thyroid cancer. Data from 37 randomized controlled trials and 19 real-world studies having 16,839 patients in placebo control group, 16,550 patients in active control group, and 13,330 patients in real-world studies were analyzed in a 2023 systematic review and meta-analysis. Compared to placebo or active control treatments, occurrence of pancreatic cancer, thyroid cancer, and all neoplasms — benign, malignant, and otherwise unspecified — were similar in the semaglutide group.

Toshi Iroku-Malize, MD, MPH, MBA, FAAFP, family physician, Zucker School of Medicine, Hempstead, New York

Audience member: What do you do about elevated liver functions after starting treatment with GLP-1 RAs, and what do you do when a patient has reached their weight loss goal?

TI-M: I recommend monitoring the liver function tests, evaluating for underlying causes, such as viral hepatitis, alcohol-related damage, or problems with other medications, and consulting a gastroenterologist or liver specialist if necessary. It’s also important to discuss the risk-benefit of continuing on the GP-1 RA for that particular patient.

Audience member: What effects will GLP-1 RAs have on sleep-disordered breathing/obstructive sleep apnea (OSA)? Are you aware of any ongoing trials addressing this subject?

TI-M: GLP-1 RAs may have beneficial effects on sleep-disordered breathing and OSA through weight loss, which can lead to a reduction in excess adipose tissue, and improvements in metabolic parameters. In terms of studies, a 2023 paper addressed this question, but more research is needed.

Audience member: Is it within a psychiatric provider’s scope of practice to prescribe GLP-1 agents for the reduction of weight gain associated with psychiatric medications?

TI-M: Obesity medicine is an interdisciplinary process. Numerous medications prescribed for mental health can contribute to obesity, and psychiatrists can play a role in collaborating with a patient’s primary care provider and/or obesity medicine specialist to determine which medications can be adjusted or replaced. It is important to remember that obesity management is not just about medications. It requires managing nutrition and activity in addition to behavioral health issues and social determinants of health. If the clinician has had the training to manage these pillars and is comfortable managing this chronic illness — similar to diabetes, hypertension, and other conditions — then this is a possibility. Otherwise, team-based care is appropriate.

Holly Lofton, MD, obesity medicine, NYU Langone Health, New York City

Audience member: Can we safely use them on patients who have had bariatric surgery and regularly develop dumping syndrome?

HL: These medications can be used after bariatric surgery in patients who meet the criteria for pharmacologic treatment. If a patient is having postoperative symptoms of dumping syndrome or excessive gastrointestinal losses from vomiting or diarrhea, dietary adjustments and other methods of managing the dumping syndrome in gastric bypass patients should be initiated before considering GLP-1 RAs because these patients do not have a functioning pylorus in their alimentary tract and these drugs are not indicated to treat dumping syndrome. The first-line approach typically involves reducing the patient’s intake of simple carbohydrates but can also include medications or surgical intervention when appropriate.

Audience member: Would teaching a patient to fast intermittently while they’re on GLP-1 RAs help them preserve weight loss if they choose to wean off the medication?

HL: Personally, I feel it is best to use the titration period and the time in which the patient is actively losing weight when on GLP-1 RAs. These are the best periods to help develop an individualized treatment plan, one that includes nutrition, activity, behavior modification, and resistance training. The patient’s lifestyle plan will likely change based on their environment and other factors. Intermittent fasting can be a part of such a plan. There is no consensus as to exactly which eating pattern will help patients maintain weight once they lose the physiologic benefit of the weight loss medications. However, studies have been published that demonstrate an average weight regain of 66% or greater when patients go from taking the maximum dose of a GLP-1 RA to taking none at all. Thus, patients should still be followed closely for weight regain when they discontinue a GLP-1 RA.

Patients may be familiar with several myths and have misconceptions about headaches and migraine, which often arise due to a combination of factors, including limited understanding of the conditions, cultural beliefs, misinformation, and the complex nature of headaches. Being aware of these myths and seeking accurate information help patients to better understand and manage their headaches.

Myth: Migraine Is the Most Common Type of Headache

This is not true. The most common type of headache is tension-type headache, and it's the kind of headache that almost everyone has from time to time. Between 40% and 80% of the US population have had some form of tension-type headache, but only about 13% of the adult population have migraine. Stress can make muscles in the head and neck tense and knotted, and these muscles can be the source of a tension-type headache. Sometimes these headaches are not at all related to muscles or stress. Neck position may also be a factor. Pain from this type of headache is usually felt on both sides of the head and presents more often as steady, dull pressure or pain that’s usually mild to moderate in intensity. The pain can be in the forehead and eyes or further back in the head. Tension-type headaches are not usually associated with nausea, vomiting, or light and sound sensitivity.

When a tension-type headache is really severe, patients could consider this headache a migraine. Clinicians can easily distinguish tension-type headache from migraine, which often presents on one side of the head, with moderate or severe intensity, is throbbing, and is associated with nausea, vomiting, and light and sound sensitivity.

Myth: Only Adults Get Headaches

False. Headaches aren’t experienced just by adults. However, unlike adults, children find it harder to explain their headaches. It is true that adults have more migraines than children; children’s migraines are often hard for doctors to recognize. A 6- to 9-year-old child is 50% less likely than an adult to have migraine, and their attacks are more often bilateral, are shorter, and respond to sleep quickly.

Myth: Migraines Are Just Really Bad Headaches

False. They are bad, but that is only a small part of the story. A migraine attack is different from other headaches; they actually are 1 of the 3 primary headache disorders, along with tension-type headache and cluster headache. A moderate or severe headache is one of the many characteristics of migraine, and some patients do not even have a headache during a migraine attack. Migraine is an inherited disease of the brain and other parts of the nervous system and can feel much worse than a normal headache. During a migraine attack, the brain does not process sensory data, such as lights, sound, or touch, properly. Patients might even experience visual, sensory, or speech problems (ie, auras) and sometime see flashing lights or zigzag lines that blink on and off or blind spots in their vision. Patients with migraine are often nauseated and severely bothered by light, sound, and even smells. Migraine headaches can last between 4 and 72 hours on average, causing disability, tiredness, and inability to think clearly or work productively, which adds to the burden of the disease. So, migraine is not just a headache. 

Myth: More Women Than Men Experience Migraine 

This is true. Epidemiologic data show a 3-fold higher incidence of migraine in women than men, starting from puberty and throughout life. From about 6 to 12 years, boys have a slightly higher incidence than girls, but then migraine occurrence levels off and becomes a disease primarily of women. The modulation of neuronal and vascular reactivity by hormones (namely estrogens and progesterone) is a crucial aspect of migraine in some women only. These hormones exert influence on a spectrum of neuromediators and neurotransmitters, potentially leading to functional and structural variations in specific brain regions associated with migraine pathogenesis. Beyond their central effects, sex hormones also modulate vascular tone. Therefore, migraine follows a pattern throughout a woman’s life corresponding to the fluctuation of estrogen. Within a year of their first menstrual period, many girls with migraine have their first attack. They are more likely to have a migraine attack just before and at the start of menses, and at other times of the month as well. They feel better when pregnant and worse after they stop breastfeeding, and they start to feel worse prior to menopause. Then they improve a few years after menopause.

While men are less at risk of having migraine, they’re more likely to have cluster headache than women (although this type of headache is rare compared with other headaches like migraine). Only about 0.1% or less of the population of adults in the US experience this type of headache. Cluster headache gets its name from the clustering of attacks occurring 2 to 6 times per day for 4 to 10 weeks and disappearing as quickly as they came. This headache pain is felt exclusively in or behind 1 eye and rarely elsewhere, on the same side of the head. There is also a clustering of other symptoms called autonomic findings, such as tearing and redness of 1 eye, stuffiness and running in 1 nostril, sweating over 1 eyebrow, drooping of 1 eyelid, and a small pupil—all on the same side of the head the pain is radiating from. Most patients have only some of these findings. Cluster headaches tend to occur every year around the same time (circannual). When a patient is in a cycle of cluster headaches, they often occur at the same time each day (circadian). These set times of the year and of the day are caused by the biological clock deep down under the brain in the hypothalamus.

Myth: All Headaches Are Psychological

This is not true. Usually the underlying cause of migraine is genetically-inherited, but each attack may be triggered by an underlying cause (eg, drop in barometric pressure, menses, certain food/drinks, lack of sleep, stress, etc). Even tension-type headaches can be triggered by muscles in the head and neck becoming tense, stressful events, or jaw issues, which in turn send out pain signals that are felt on both sides of the head.

Many years ago (ie, 1950s-1960s), it was thought that the underlying cause of migraine in women was psychological issues; that has been disproven many times. Both men and women have migraine, and they both can have coexisting psychological issues (ie, depression, anxiety, and other psychiatric problems). 

Myth: Migraines Aren’t Serious

Most types of migraine in and of themselves are not serious; however, chronic migraine can continue for years and is debilitating and disabling—becoming a serious issue for patients. These patients usually take many medications, are obese, can have big changes in weight and severe insomnia, don’t exercise enough, and develop other illnesses. Migraine can severely impact quality of life; many people living with migraine have reported reduced productivity while at work, lack of promotion, loss of jobs, and a disruption in their family, social, and leisure activities.

Migraine attacks vary from one person to another and can be quite different from one attack to another in the same person. Hemiplegic migraine, a rare and distinct subtype that is sometimes inherited, is characterized by neurologic symptoms (multiple auras, including a significant weakness or paralysis on 1 side of the body). Although these patients seem much sicker and have multiple types of auras and 1-sided weakness with a prolonged headache, most recover without serious consequences. 

Myth: Lack of Sleep Causes Migraine 

Yes, lack of sleep is a known trigger for migraine in many people, but lack of sleep is not the cause of migraine. Sleep deprivation and irregular sleep patterns can disrupt the delicate balance of neurotransmitters and hormones in the brain, potentially triggering migraine in susceptible individuals. Additionally, inadequate sleep may contribute to increased stress and tension, which are also common triggers for migraine. In fact, many people with migraine do have sleep issues, which can range from trouble falling asleep to early morning awakening without being able to get back to sleep or frequently interrupted sleep each night. Correcting the sleep problem is part of the migraine therapy. Patients should be checked for sleep apnea if they wake with headache in the morning. Medication overuse headache should also be considered.

Establishing a regular sleep routine and ensuring an adequate amount of sleep can be important components of managing migraine symptoms, particularly for those who find a connection between their sleep patterns and the onset of a migraine attack. However, the relationship between sleep and migraine can vary widely among individuals, and other factors may also contribute to migraine triggers.

Myth: Caffeine Causes Migraine

This is a myth; caffeine does not cause migraine but definitely can be a trigger for some people. Coffee and caffeine and migraine have a complex relationship: excessive caffeine consumption or withdrawal can trigger migraine attacks, but caffeine can also help alleviate headaches (including migraine) due to its analgesic properties. Caffeine is a major component of many over-the-counter medicines for migraine. Some people find drinking coffee or a soda or taking a caffeine tablet at the onset of a migraine attack lowers the intensity of a migraine headache. Regular use of caffeine, either as “treatment” or for pleasure, is not advised in patients with migraine. Most doctors limit caffeine to a regular cup of coffee or tea per day, with no caffeine-containing sodas or chocolate in their patients with migraine; caffeine withdrawal is also a frequent migraine trigger. Patients can notice withdrawal headaches when they stop coffee, even if they are only consuming 1 cup per day. Most people drink a lot more.

Myth: Headache Medicine Will Cure Migraine

False. There currently is no “cure” for migraine. There are several medicines available that certainly can help prevent, abort, or control symptoms of migraine. Some of these medications include over-the-counter analgesics; triptans (like sumatriptan or rizatriptan); gepants, which are small molecule CGRP (calcitonin gene-related peptide) antagonists; CGRP antibodies given by injection; antidepressants; antiseizure medicines; and beta-blockers. 

Myth: You Cannot Take Any Migraine Medications During Pregnancy

Migraine medications, such as triptans, are relatively safe during pregnancy, particularly after the first trimester. Acetaminophen in low doses is safe as well, but some of the preventive antiseizure medications should be avoided due to the risk of halting the pregnancy or producing a congenital malformation. Noninvasive wearable devices (such as Nerivio), biofeedback training, mindfulness, and relaxation techniques are particularly appealing to pregnant women as they have high efficacy with virtually no lasting side effects. 

Although patients who are pregnant might have an increased flurry of migraine headaches in the first trimester of their pregnancy, they will most likely have a decreased number of attacks in the next 2 trimesters of their pregnancy, making them feel really well. The first trimester is a dangerous time for fetuses to be exposed to certain medicines that are foreign to them, as their organs are still being formed. There are medicines that doctors feel are less problematic both for acute care and prevention of migraine during pregnancy; therefore, patients with a history of migraine should always consult with their obstetrician-gynecologist and a neurologist (or other doctor they usually see for their migraine care) before taking any medication if they are planning a pregnancy or are pregnant. 

Effective nonpharmaceutical options are available for all patients with migraine, whether pregnant or not. Maintaining a healthy lifestyle, which includes getting 7 to 10 hours of sleep each night, drinking plenty of water each day, getting ample nutrition from healthy foods, and eliminating as many sources of extra stress as possible can help reduce the risk of a migraine, even when exposed to a known trigger.

Medications may also lead to headaches by a phenomenon called medication overuse headache, if the rescue medication is taken too often. Clinicians recommend no more than 2 days per week of any acute care medication and taking a good preventive medication if needed.

Myth: “Migraine Diets” Cure Migraine

This is false. Avoiding known food triggers can reduce the risk of a migraine attack, but a diet regimen is not a cure. Although eating healthy foods and avoiding certain kinds of food that trigger migraine can eliminate triggering the episodes, there are other factors to take into account. For instance, the migraine diet cannot address a lack of sleep, stress, or hormonal changes a person experiences. Only very few patients with migraine can say their medication has cured their migraine, but it could happen.

Myth: Dietary Supplements Can Cure Migraine

This myth is not true. Supplements can help migraine headache or prevent triggering it, but they won’t cure it. Supplements, such as magnesium, vitamin D3, coenzyme Q10, vitamin B2 (riboflavin), feverfew, melatonin, and vitamin B2 are important additions to the migraine treatment armamentarium, but no one specific vitamin/mineral or supplement has been proven to help prevent or relieve migraine for everyone. They help some people immensely and do little for others, just as with any pharmacologic agent.

Myth: It’s Not a Migraine Unless You Experience Aura

This is not true, as most migraines present without aura. Migraine with typical aura affects 30% of patients with migraine.

Myth: Researchers No Longer Investigate Migraine

False; there are several ongoing studies working to address the pathophysiology of migraine and find new treatment options. Recently, neuromodulation devices have entered the market. One such device from Theranica (called Nerivio) now has clearance from the US Food and Drug Administration for acute and preventive migraine treatment from age 12 and up. One phase 4 study by Theranica shows that Nerivio appears to be safe during pregnancy.                                                                                                                                                         

Several migraine studies of note include the following:

• OnabotulinumtoxinA as a treatment for hemiplegic migraine: This project aims to evaluate the response to onabotulinumtoxinA treatments in patients with hemiplegic migraine evaluated at Mayo Clinic.

• Occipital nerve stimulation for migraine: OPTIMISE. This study is evaluating the safety and efficacy of occipital nerve stimulation (ONS) using the Boston Scientific Corporation (BSC) Precision™ System in the management of intractable chronic migraine, when used in conjunction with antimigraine medications.

• The Medication Overuse Treatment Strategy trial: This study is comparing the outcomes among patients randomized to 1 of the 2 treatment strategies for treating patients who have chronic migraine with medication overuse.

• Metformin is being investigated as a treatment for the prevention of episodic migraine.

Myth: Migraine Cannot Be Diagnosed Without an Imaging Exam

This is false. Migraine is a clinical diagnosis and does not need any imaging to confirm. Imaging is indicated only if the symptoms are not clear or if there are neurologic symptoms or warning signs accompanying the migraine. In such cases, imaging would be warranted to rule out other pathologies. A magnetic resonance imaging scan is performed to rule out other pathology, not to diagnose migraine. A clinician must identify a pattern in the patient’s history according to the diagnostic criteria of the International Headache Society to diagnose migraine, which include that the patient had 5 previous attacks without aura or 2 attacks with aura.

Summary

Headaches, especially migraine, can be unpleasant and disabling and can significantly affect a patient’s quality of life. However, pharmaceutical and nonpharmaceutical interventions that can help are available. Lifestyle changes, including diet, sleep, and stress reduction can ease symptoms and reduce the frequency of migraine attacks. As researchers continue to investigate the pathophysiology of migraine, they are sure to identify better treatments and, perhaps one day—a cure.

rapaport-tan_0_4_1_1_4.jpg

Patients may be familiar with several myths and have misconceptions about headaches and migraine, which often arise due to a combination of factors, including limited understanding of the conditions, cultural beliefs, misinformation, and the complex nature of headaches. Being aware of these myths and seeking accurate information help patients to better understand and manage their headaches.

Myth: Migraine Is the Most Common Type of Headache

This is not true. The most common type of headache is tension-type headache, and it's the kind of headache that almost everyone has from time to time. Between 40% and 80% of the US population have had some form of tension-type headache, but only about 13% of the adult population have migraine. Stress can make muscles in the head and neck tense and knotted, and these muscles can be the source of a tension-type headache. Sometimes these headaches are not at all related to muscles or stress. Neck position may also be a factor. Pain from this type of headache is usually felt on both sides of the head and presents more often as steady, dull pressure or pain that’s usually mild to moderate in intensity. The pain can be in the forehead and eyes or further back in the head. Tension-type headaches are not usually associated with nausea, vomiting, or light and sound sensitivity.

When a tension-type headache is really severe, patients could consider this headache a migraine. Clinicians can easily distinguish tension-type headache from migraine, which often presents on one side of the head, with moderate or severe intensity, is throbbing, and is associated with nausea, vomiting, and light and sound sensitivity.

Myth: Only Adults Get Headaches

False. Headaches aren’t experienced just by adults. However, unlike adults, children find it harder to explain their headaches. It is true that adults have more migraines than children; children’s migraines are often hard for doctors to recognize. A 6- to 9-year-old child is 50% less likely than an adult to have migraine, and their attacks are more often bilateral, are shorter, and respond to sleep quickly.

Myth: Migraines Are Just Really Bad Headaches

False. They are bad, but that is only a small part of the story. A migraine attack is different from other headaches; they actually are 1 of the 3 primary headache disorders, along with tension-type headache and cluster headache. A moderate or severe headache is one of the many characteristics of migraine, and some patients do not even have a headache during a migraine attack. Migraine is an inherited disease of the brain and other parts of the nervous system and can feel much worse than a normal headache. During a migraine attack, the brain does not process sensory data, such as lights, sound, or touch, properly. Patients might even experience visual, sensory, or speech problems (ie, auras) and sometime see flashing lights or zigzag lines that blink on and off or blind spots in their vision. Patients with migraine are often nauseated and severely bothered by light, sound, and even smells. Migraine headaches can last between 4 and 72 hours on average, causing disability, tiredness, and inability to think clearly or work productively, which adds to the burden of the disease. So, migraine is not just a headache. 

Myth: More Women Than Men Experience Migraine 

This is true. Epidemiologic data show a 3-fold higher incidence of migraine in women than men, starting from puberty and throughout life. From about 6 to 12 years, boys have a slightly higher incidence than girls, but then migraine occurrence levels off and becomes a disease primarily of women. The modulation of neuronal and vascular reactivity by hormones (namely estrogens and progesterone) is a crucial aspect of migraine in some women only. These hormones exert influence on a spectrum of neuromediators and neurotransmitters, potentially leading to functional and structural variations in specific brain regions associated with migraine pathogenesis. Beyond their central effects, sex hormones also modulate vascular tone. Therefore, migraine follows a pattern throughout a woman’s life corresponding to the fluctuation of estrogen. Within a year of their first menstrual period, many girls with migraine have their first attack. They are more likely to have a migraine attack just before and at the start of menses, and at other times of the month as well. They feel better when pregnant and worse after they stop breastfeeding, and they start to feel worse prior to menopause. Then they improve a few years after menopause.

While men are less at risk of having migraine, they’re more likely to have cluster headache than women (although this type of headache is rare compared with other headaches like migraine). Only about 0.1% or less of the population of adults in the US experience this type of headache. Cluster headache gets its name from the clustering of attacks occurring 2 to 6 times per day for 4 to 10 weeks and disappearing as quickly as they came. This headache pain is felt exclusively in or behind 1 eye and rarely elsewhere, on the same side of the head. There is also a clustering of other symptoms called autonomic findings, such as tearing and redness of 1 eye, stuffiness and running in 1 nostril, sweating over 1 eyebrow, drooping of 1 eyelid, and a small pupil—all on the same side of the head the pain is radiating from. Most patients have only some of these findings. Cluster headaches tend to occur every year around the same time (circannual). When a patient is in a cycle of cluster headaches, they often occur at the same time each day (circadian). These set times of the year and of the day are caused by the biological clock deep down under the brain in the hypothalamus.

Myth: All Headaches Are Psychological

This is not true. Usually the underlying cause of migraine is genetically-inherited, but each attack may be triggered by an underlying cause (eg, drop in barometric pressure, menses, certain food/drinks, lack of sleep, stress, etc). Even tension-type headaches can be triggered by muscles in the head and neck becoming tense, stressful events, or jaw issues, which in turn send out pain signals that are felt on both sides of the head.

Many years ago (ie, 1950s-1960s), it was thought that the underlying cause of migraine in women was psychological issues; that has been disproven many times. Both men and women have migraine, and they both can have coexisting psychological issues (ie, depression, anxiety, and other psychiatric problems). 

Myth: Migraines Aren’t Serious

Most types of migraine in and of themselves are not serious; however, chronic migraine can continue for years and is debilitating and disabling—becoming a serious issue for patients. These patients usually take many medications, are obese, can have big changes in weight and severe insomnia, don’t exercise enough, and develop other illnesses. Migraine can severely impact quality of life; many people living with migraine have reported reduced productivity while at work, lack of promotion, loss of jobs, and a disruption in their family, social, and leisure activities.

Migraine attacks vary from one person to another and can be quite different from one attack to another in the same person. Hemiplegic migraine, a rare and distinct subtype that is sometimes inherited, is characterized by neurologic symptoms (multiple auras, including a significant weakness or paralysis on 1 side of the body). Although these patients seem much sicker and have multiple types of auras and 1-sided weakness with a prolonged headache, most recover without serious consequences.

Most doctors limit caffeine to a regular cup of coffee or tea per day, with no caffeine-containing sodas or chocolate in their patients with migraine; caffeine withdrawal is also a frequent migraine trigger. Patients can notice withdrawal headaches when they stop coffee, even if they are only consuming 1 cup per day. Most people drink a lot more.

Some of these medications include over-the-counter analgesics; triptans (like sumatriptan or rizatriptan); gepants, which are small molecule CGRP (calcitonin gene-related peptide) antagonists; CGRP antibodies given by injection; antidepressants; antiseizure medicines; and beta-blockers. 

Myth: You Cannot Take Any Migraine Medications During Pregnancy

Migraine medications, such as triptans, are relatively safe during pregnancy, particularly after the first trimester. Acetaminophen in low doses is safe as well, but some of the preventive antiseizure medications should be avoided due to the risk of halting the pregnancy or producing a congenital malformation. Noninvasive wearable devices (such as Nerivio), biofeedback training, mindfulness, and relaxation techniques are particularly appealing to pregnant women as they have high efficacy with virtually no lasting side effects. 

Although patients who are pregnant might have an increased flurry of migraine headaches in the first trimester of their pregnancy, they will most likely have a decreased number of attacks in the next 2 trimesters of their pregnancy, making them feel really well. The first trimester is a dangerous time for fetuses to be exposed to certain medicines that are foreign to them, as their organs are still being formed. There are medicines that doctors feel are less problematic both for acute care and prevention of migraine during pregnancy; therefore, patients with a history of migraine should always consult with their obstetrician-gynecologist and a neurologist (or other doctor they usually see for their migraine care) before taking any medication if they are planning a pregnancy or are pregnant. 

Effective nonpharmaceutical options are available for all patients with migraine, whether pregnant or not. Maintaining a healthy lifestyle, which includes getting 7 to 10 hours of sleep each night, drinking plenty of water each day, getting ample nutrition from healthy foods, and eliminating as many sources of extra stress as possible can help reduce the risk of a migraine, even when exposed to a known trigger.

Medications may also lead to headaches by a phenomenon called medication overuse headache, if the rescue medication is taken too often. Clinicians recommend no more than 2 days per week of any acute care medication and taking a good preventive medication if needed.

Myth: “Migraine Diets” Cure Migraine

This is false. Avoiding known food triggers can reduce the risk of a migraine attack, but a diet regimen is not a cure. Although eating healthy foods and avoiding certain kinds of food that trigger migraine can eliminate triggering the episodes, there are other factors to take into account. For instance, the migraine diet cannot address a lack of sleep, stress, or hormonal changes a person experiences. Only very few patients with migraine can say their medication has cured their migraine, but it could happen.

Myth: Dietary Supplements Can Cure Migraine

This myth is not true. Supplements can help migraine headache or prevent triggering it, but they won’t cure it. Supplements, such as magnesium, vitamin D3, coenzyme Q10, vitamin B2 (riboflavin), feverfew, melatonin, and vitamin B2 are important additions to the migraine treatment armamentarium, but no one specific vitamin/mineral or supplement has been proven to help prevent or relieve migraine for everyone. They help some people immensely and do little for others, just as with any pharmacologic agent.

Myth: It’s Not a Migraine Unless You Experience Aura

This is not true, as most migraines present without aura. Migraine with typical aura affects 30% of patients with migraine.

Myth: Researchers No Longer Investigate Migraine

False; there are several ongoing studies working to address the pathophysiology of migraine and find new treatment options. Recently, neuromodulation devices have entered the market. One such device from Theranica (called Nerivio) now has clearance from the US Food and Drug Administration for acute and preventive migraine treatment from age 12 and up. One phase 4 study by Theranica shows that Nerivio appears to be safe during pregnancy.                                                                                                                                                         

Several migraine studies of note include the following:

• OnabotulinumtoxinA as a treatment for hemiplegic migraine: This project aims to evaluate the response to onabotulinumtoxinA treatments in patients with hemiplegic migraine evaluated at Mayo Clinic.

• Occipital nerve stimulation for migraine: OPTIMISE. This study is evaluating the safety and efficacy of occipital nerve stimulation (ONS) using the Boston Scientific Corporation (BSC) Precision™ System in the management of intractable chronic migraine, when used in conjunction with antimigraine medications.

• The Medication Overuse Treatment Strategy trial: This study is comparing the outcomes among patients randomized to 1 of the 2 treatment strategies for treating patients who have chronic migraine with medication overuse.

• Metformin is being investigated as a treatment for the prevention of episodic migraine.

Myth: Migraine Cannot Be Diagnosed Without an Imaging Exam

This is false. Migraine is a clinical diagnosis and does not need any imaging to confirm. Imaging is indicated only if the symptoms are not clear or if there are neurologic symptoms or warning signs accompanying the migraine. In such cases, imaging would be warranted to rule out other pathologies. A magnetic resonance imaging scan is performed to rule out other pathology, not to diagnose migraine. A clinician must identify a pattern in the patient’s history according to the diagnostic criteria of the International Headache Society to diagnose migraine, which include that the patient had 5 previous attacks without aura or 2 attacks with aura.

Summary

Headaches, especially migraine, can be unpleasant and disabling and can significantly affect a patient’s quality of life. However, pharmaceutical and nonpharmaceutical interventions that can help are available. Lifestyle changes, including diet, sleep, and stress reduction can ease symptoms and reduce the frequency of migraine attacks. As researchers continue to investigate the pathophysiology of migraine, they are sure to identify better treatments and, perhaps one day—a cure.

The COVID-19 pandemic may no longer be a global public health emergency, but millions continue to struggle with the aftermath: Long COVID. New research and clinical anecdotes suggest that certain individuals are more likely to be afflicted by the condition, nearly 4 years after the virus emerged. 

People with a history of allergies, anxiety or depression, arthritis, and autoimmune diseases and women are among those who appear more vulnerable to developing long COVID, said doctors who specialize in treating the condition.

Many patients with long COVID struggle with debilitating fatigue, brain fog, and cognitive impairment. The condition is also characterized by a catalog of other symptoms that may be difficult to recognize as long COVID, experts said. That’s especially true when patients may not mention seemingly unrelated information, such as underlying health conditions that might make them more vulnerable. This makes screening for certain conditions and investigating every symptom especially important. 

The severity of a patient’s initial infection is not the only determining factor for developing long COVID, experts said.

“Don’t judge the person based on how sick they were initially,” said Mark Bayley, MD, medical director of the Toronto Rehabilitation Institute at University Health Network and a professor with the Temerty Faculty of Medicine at the University of Toronto. “You have to evaluate every symptom as best you can to make sure you’re not missing anything else.” 

Someone who only had a bad cough or felt really unwell for just a few days and recovered but started feeling rotten again later — “that’s the person that we are seeing for long COVID,” said Dr. Bayley. 

While patients who become severely sick and require hospitalization have a higher risk of developing long COVID, this group size is small compared with the much larger number of people infected overall. As a result, despite the lower risk, those who only become mild to moderately sick make up the vast majority of patients in long COVID clinics. 

A small Northwestern Medicine study found that 41% of patients with long COVID never tested positive for COVID-19 but were found to have antibodies that indicated exposure to the virus. 

Doctors treating patients with long COVID should consider several risk factors, specialists said. They include:

• A history of asthma, eczema, or allergies
• Signs of autonomic nervous system dysfunction
• Preexisting immune system issues
• Chronic infections
• Diabetes
• Being slightly overweight
• A preexisting history of anxiety or depression
• Joint hypermobility ( being “double-jointed” with pain and other symptoms)

Screening for Allergies

Alba Azola, MD, assistant professor of Physical Medicine and Rehabilitation at Johns Hopkins Medicine, said a history of asthma, allergies, and eczema and an onset of new food allergies may be an important factor in long COVID that doctors should consider when evaluating at-risk patients.

It is important to identify this subgroup of patients because they respond to antihistamines and mast cell stabilizers, which not only relieve their allergy symptoms but may also help improve overall fatigue and their tolerance for basic activities like standing, Dr. Azola said.

A recently published systemic review of prospective cohort studies on long COVID also found that patients with preexisting allergic conditions like asthma or rhinitis may be linked to a higher risk of developing long COVID. The authors cautioned, however, that the evidence for the link is uncertain and more rigorous research is needed.

“It stands to reason that if your immune system tends to be a bit hyperactive that triggering it with a virus will make it worse,” said Dr. Bayley.


 

Signs of Dysautonomia, Joint Hypermobility

Patients should also be screened for signs and symptoms of dysautonomia, or autonomic nervous system disorder, such as postural orthostatic tachycardia syndrome (POTS) or another type of autonomic dysfunction, doctors said.

“There’s a whole list because the autonomic nervous system involves every part of your body, every system,” Dr. Azola said.

Issues with standing, vision, digestion, urination, and bowel movement, for example, appear to be multisystemic problems but may all be linked to autonomic dysfunction, she explained.

Patients who have POTS usually experience a worsening of symptoms after COVID infection, Dr. Azola said, adding that some patients may have even assumed their pre-COVID symptoms of POTS were normal. 

She also screens for joint hypermobility or hypermobile Ehlers-Danlos syndrome, which affects connective tissue. Research has long shown a relationship between autonomic dysfunction, mast cell activation syndrome (repeated severe allergy symptoms that affect multiple systems), and the presence of hypermobility, Dr. Azola said. She added that gentle physical therapy can be helpful for patients with hypermobility issues.

Previous studies before and during the pandemic have also found that a substantial subset of patients with myalgic encephalomyelitis/chronic fatigue syndrome, which shares many similarities with long COVID, also have connective tissue/hypermobility disorders.
 

Depression, Anxiety, and Female Patients

People with a preexisting history of anxiety or depression also appear to be at a higher risk for long COVID, Dr. Bayley said, noting that patients with these conditions appear more vulnerable to brain fog and other difficulties brought on by COVID infection. Earlier research found biochemical evidence of brain inflammation that correlates with symptoms of anxiety in patients with long COVID.

“We know that depression is related to neurotransmitters like adrenaline and serotonin,” Dr. Bayley said. “The chronic inflammation that’s associated with COVID — this will make people feel more depressed because they’re not getting the neurotransmitters in their brain releasing at the right times.”

It may also put patients at a risk for anxiety due to fears of post-exertional malaise (PEM), where symptoms worsen after even very minor physical or mental exertion and can last days or weeks.

“You can see how that leads to a bit of a vicious cycle,” said Dr. Bayley, explaining that the cycle of fear and avoidance makes patients less active and deconditioned. But he added that learning to manage their activity can actually help mitigate PEM due to the anti-inflammatory effects of exercise, its positive impact on mood, and benefits to the immune and cardiovascular systems. 

Meanwhile, a number of epidemiologic studies have found a higher prevalence of long COVID among women. Perimenopausal and menopausal women in particular appeared more prone, and at least one study reported that women under 50 years were five times more likely to develop post-COVID symptoms than men.

A recent small UK study that focused on COVID-19 hospitalizations found that women who had lower levels of inflammatory biomarkers at admission were more likely to experience certain long-term symptoms like muscle ache, low mood and anxiety, adding to earlier research linking female patients, long COVID, and neuropsychiatric symptoms. 


 

History of Immune Dysfunction, Diabetes, Elevated Body Mass Index (BMI)

Immune dysfunction, a history of recurrent infections, or chronic sinus infections are also common among patients under Dr. Azola and her team’s care. Those who have arthritis or other autoimmune diseases such as lupus also appear more vulnerable, Dr. Bayley said, along with patients who have diabetes or a little overweight.

Recent research out of the University of Queensland found that being overweight can negatively affect the body’s immune response to the SARS-CoV-2 virus. Blood samples collected 13 months after infection, for example, found that individuals with a higher BMI had lower antibody activity and a reduced percentage of relevant B cells that help build antibodies to fight the virus. Being overweight did not affect the antibody response to the COVID-19 vaccines, however, giving further support for vaccination over infection-induced immunity as an important protective factor, researchers said.
 

Narrowing the Information Gap

The latest Centers for Centers for Disease Control and Prevention’s Household Pulse Survey estimates that 14% of all American adults have had long COVID at some point, with more than 5% of the entire adult population currently experiencing long COVID. With millions of Americans affected, experts and advocates highlight the importance of bridging the knowledge gap with primary care doctors. 

Long COVID specialists said understanding these connections helps guide treatment plans and manage symptoms, such as finding the right medications, improving tolerance, optimizing sleep, applying cognitive strategies for brain fog, dietary changes, respiratory exercises to help with shortness of breath, and finding the fine line between what causes PEM and what doesn’t. 

“Whenever you see a disease like this one, you always have to ask yourself, is there an alternative way of looking at this that might explain what we’re seeing?” said Dr. Bayley. “It remains to be said that all bets are still open and that we need to continue to be very broad thinking about this.”

Non-Hodgkin lymphomas (NHLs) are cancers that arise in a type of white blood cell called the lymphocyte. NHLs are divided into B- and T-cell subtypes, as well as aggressive and indolent forms. Management varies widely depending on the disease type. We will focus on the most common type of NHL, diffuse large B-cell lymphoma (DLBCL), for which there have been significant treatment advances in recent years. 

DLBCL is curable in about two-thirds of patients using chemoimmunotherapy. The longstanding frontline treatment for this disease has been R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone). In 2023, an antibody-drug conjugate against the B-cell surface protein CD79b, polatuzumab vedotin, was approved by the US Food and Drug Administration (FDA) in combination with R-CHP (rituximab, cyclophosphamide, doxorubicin, prednisone) for newly diagnosed DLBCL based on an improvement in progression-free survival at 2 years in patients with high-risk disease features enrolled in the POLARIX study.

For patients who do not respond to the initial treatment or in whom the disease recurs, the historical standard of care treatment strategy was high-dose chemotherapy followed by autologous stem cell transplant (ASCT). Unfortunately, this approach is not feasible or not successful in a significant percentage of patients with relapsed or refractory DLBCL. 

A newer strategy for DLBCL is chimeric antigen receptor (CAR) T-cell therapy. In this treatment, T cells are collected from a patient and genetically modified to target a protein on the lymphoma cells called CD19. This type of treatment was initially approved in the third-line setting for DLBCL based on the ZUMA-1 (axi-cel), JULIET (tisa-cel), and TRANSCEND (liso-cel) clinical trials. More recently, in 2022, 2 of these agents received approval in the second-line setting in patients who relapse or are refractory to initial treatment within 1 year; axi-cel was approved based on the ZUMA-7 trial and liso-cel was approved based on the TRANSFORM trial. 

Unfortunately, not all patients are eligible for ASCT and CAR T-cell therapy due to factors including age, comorbidities, and disease characteristics. Some patients prefer alternative therapies based on the potential side effects of CAR T-cell therapy and ASCT. Toxicities associated with CAR T-cell therapy include an inflammatory response called cytokine release syndrome and neurologic events. 

For patients who are not eligible for or who relapse after ASCT or CAR T-cell therapy, several alternative treatment options are FDA approved. Novel strategies include polatuzumab vedotin with bendamustine and rituximab and tafasitamab plus lenalidomide. Tafasitamab is a monoclonal antibody against CD19 and lenalidomide is an oral anticancer agent originally approved for use in multiple myeloma. Lenalidomide is also effective and commonly used in other NHL subtypes. 

In 2023, a new category of treatment called bispecific antibodies was approved in patients with DLBCL in whom the disease recurs after 2 lines of therapy. These drugs (epcoritamab and glofitamab) are a form of immunotherapy that connects B cells with T cells to enable a person’s own immune system to better fight the lymphoma. While these drugs can have similar toxicities as CAR T-cell therapy, the severity and incidence are much lower. In contrast to CAR T-cell therapy, which requires only 1 infusion, these drugs are given regularly in either subcutaneous or intravenous form for several months. 

Two other FDA-approved treatment options for relapsed and refractory DLBCL are loncastuximab tesirine, an antibody-drug conjugate targeting CD19 with approval based on the results of the LOTIS-2 trial, and the oral selective inhibitor of nuclear export called selinexor, based on the results from the SADAL trial. Selinexor is a fully synthetic small-molecule compound, developed by means of a structure-based drug design process known as induced-fit docking. It binds to a cysteine residue in the nuclear export signal groove of exportin 1. Selinexor is approved for use in adults with relapsed or refractory DLBCL who have received at least 2 types of systemic therapy. Trials investigating these agents in combination with other novel treatments are ongoing. 

The treatment landscape for DLBCL has changed markedly over the past several years. Therapies can be tailored for individual patients based on their disease status and characteristics, comorbidities, and treatment preferences. Research with novel strategies continues with the goal of a cure for all patients diagnosed with DLBCL.

The longstanding frontline treatment for this disease has been R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone). In 2023, an antibody-drug conjugate against the B-cell surface protein CD79b, polatuzumab vedotin, was approved by the US Food and Drug Administration (FDA) in combination with R-CHP (rituximab, cyclophosphamide, doxorubicin, prednisone) for newly diagnosed DLBCL based on an improvement in progression-free survival at 2 years in patients with high-risk disease features enrolled in the POLARIX study.

For patients who do not respond to the initial treatment or in whom the disease recurs, the historical standard of care treatment strategy was high-dose chemotherapy followed by autologous stem cell transplant (ASCT). Unfortunately, this approach is not feasible or not successful in a significant percentage of patients with relapsed or refractory DLBCL. 

A newer strategy for DLBCL is chimeric antigen receptor (CAR) T-cell therapy. In this treatment, T cells are collected from a patient and genetically modified to target a protein on the lymphoma cells called CD19. This type of treatment was initially approved in the third-line setting for DLBCL based on the ZUMA-1 (axi-cel), JULIET (tisa-cel), and TRANSCEND (liso-cel) clinical trials. More recently, in 2022, 2 of these agents received approval in the second-line setting in patients who relapse or are refractory to initial treatment within 1 year; axi-cel was approved based on the ZUMA-7 trial and liso-cel was approved based on the TRANSFORM trial. 

Unfortunately, not all patients are eligible for ASCT and CAR T-cell therapy due to factors including age, comorbidities, and disease characteristics. Some patients prefer alternative therapies based on the potential side effects of CAR T-cell therapy and ASCT. Toxicities associated with CAR T-cell therapy include an inflammatory response called cytokine release syndrome and neurologic events. 

For patients who are not eligible for or who relapse after ASCT or CAR T-cell therapy, several alternative treatment options are FDA approved. Novel strategies include polatuzumab vedotin with bendamustine and rituximab and tafasitamab plus lenalidomide. Tafasitamab is a monoclonal antibody against CD19 and lenalidomide is an oral anticancer agent originally approved for use in multiple myeloma. Lenalidomide is also effective and commonly used in other NHL subtypes. 

In 2023, a new category of treatment called bispecific antibodies was approved in patients with DLBCL in whom the disease recurs after 2 lines of therapy. These drugs (epcoritamab and glofitamab) are a form of immunotherapy that connects B cells with T cells to enable a person’s own immune system to better fight the lymphoma. While these drugs can have similar toxicities as CAR T-cell therapy, the severity and incidence are much lower. In contrast to CAR T-cell therapy, which requires only 1 infusion, these drugs are given regularly in either subcutaneous or intravenous form for several months. 

Two other FDA-approved treatment options for relapsed and refractory DLBCL are loncastuximab tesirine, an antibody-drug conjugate targeting CD19 with approval based on the results of the LOTIS-2 trial, and the oral selective inhibitor of nuclear export called selinexor, based on the results from the SADAL trial. Selinexor is a fully synthetic small-molecule compound, developed by means of a structure-based drug design process known as induced-fit docking. It binds to a cysteine residue in the nuclear export signal groove of exportin 1. Selinexor is approved for use in adults with relapsed or refractory DLBCL who have received at least 2 types of systemic therapy. Trials investigating these agents in combination with other novel treatments are ongoing. 

The treatment landscape for DLBCL has changed markedly over the past several years. Therapies can be tailored for individual patients based on their disease status and characteristics, comorbidities, and treatment preferences. Research with novel strategies continues with the goal of a cure for all patients diagnosed with DLBCL.

Non-Hodgkin lymphomas (NHLs) are cancers that arise in a type of white blood cell called the lymphocyte. NHLs are divided into B- and T-cell subtypes, as well as aggressive and indolent forms. Management varies widely depending on the disease type. We will focus on the most common type of NHL, diffuse large B-cell lymphoma (DLBCL), for which there have been significant treatment advances in recent years.

Results from TROPION-Breast01, EMBER, and OPERA were recently presented at ESMO Breast Cancer 2023. 

A number of exciting updates on systemic therapies for the treatment of hormone receptor (HR)-positive, HER2-negative breast cancer were presented at the European Society for Medical Oncology (ESMO) Breast Cancer 2023, including novel endocrine agents and antibody-drug conjugates (ADC). We have highlighted 3 key studies, including the phase III study of datopotamab deruxtecan (Dato-DXd), the new trophoblast cell surface antigen 2 (TROP2)-directed ADC; the phase I study of imlunestrant, a selective estrogen receptor degrader (SERD); and phase I/II data evaluating OP-1250, a small molecule oral complete estrogen receptor antagonist (CERAN) and SERD. 

TROPION-Breast01: Dato-DXd Improves Progression-Free Survival Compared With Systemic Chemotherapy

Study synopsis

Dato-DXd, an investigational TROP2 ADC, resulted in significantly improved progression-free survival (PFS) when compared with investigator’s choice chemotherapy (ICC) in individuals with inoperable or metastatic HR-positive, HER2-low or HER2-negative breast cancer, according to a randomized phase III trial. 

Participants in the study had progressed on or were not eligible for endocrine therapy and had received 1 or 2 prior lines of systemic chemotherapy. Patients were randomized to receive either 6 mg/kg of Dato-DXd once every 3 weeks (n=365; median age 56), or ICC with eribulin, vinorelbine, capecitabine, or gemcitabine (n=367; median age 54) until progression or unacceptable toxicity. Blinded independent review assessed PFS and overall survival. Among the results: 

• In the blinded independent review, PFS was 6.9 months for Dato-DXd and 4.9 months for ICC (HR 0.63 [95% CI: 0.52, 0.76]; p<0.0001)

• At 6 months, 53% of participants receiving Dato-DXd achieved PFS, compared with 39% in the systemic chemotherapy contingent

• In the Dato-DXd group, treatment-related adverse events led to dose reductions in 23% and discontinuation in 3% of patients

• In the systemic chemotherapy cohort, the dose reduction and discontinuation rates were 32% and 3%, respectively

• At the time data were reported at ESMO, overall survival data were not mature but trending favorably for Dato-DXd

The investigators concluded that Dato-DXd is a promising novel treatment option for individuals with inoperable or metastatic HR-positive, HER2-low or HER2-negative breast cancer who have received prior chemotherapy.

EMBER: Imlunestrant Alone or With a Kinase Inhibitor: Early Safety and Efficacy Results Are Encouraging

Study synopsis

The SERD imlunestrant—used either alone or combined with a kinase inhibitor—showed favorable efficacy in individuals with estrogen receptor (ER)-positive, HER2-negative advanced breast cancer, according to the first set of clinical data reported from the phase 1a/b EMBER study. 

Key eligibility criteria for phase 1b enrollment included prior sensitivity to endocrine therapy, ≤2 prior therapies, and a PIK3CA mutation (alpelisib arm only). Prior therapies included endocrine therapy (100%), CDK4/6 inhibitors (100%), hormonal therapy with fulvestrant (35%), and chemotherapy (17%). At baseline, 46% of patients had visceral disease and 46% had an ESR1 mutation. Participants received imlunestrant alone (n=114) or with the kinase inhibitors everolimus (n=42) or alpelisib (n=21). Investigators assessed each regimen’s safety profile, as well as the objective response rate and clinical benefit rate. 

The safety profile of each regimen was similar to those seen with everolimus and alpelisib alone. No cardiac or ocular toxicities were observed. Regarding grade ≥3 treatment-related adverse events: 

• The imlunestrant alone group experienced fatigue (2%) and neutropenia (2%)

• The imlunestrant + everolimus group experienced hypertriglyceridemia (5%) and aspartate aminotransferase increase (5%)

• The imlunestrant + alpelisib cohort experienced rash (43%) and hyperglycemia (10%).

• In the imlunestrant alone group, 2% of individuals had their doses reduced due to adverse events; none discontinued treatment

• In the imlunestrant + everolimus cohort, 12% of patients experienced dose reduction due to everolimus and 2% due to both medications; 2% discontinued treatment due to everolimus

• In the imlunestrant + alpelisib cohort, 24% of patients experienced dose reduction due to alpelisib and 14% due to both medications; 29% discontinued treatment due to alpelisib

Regarding efficacy:

• The objective response rates in the imlunestrant alone, imlunestrant + everolimus, and imlunestrant + alpelisib groups were 9%, 21%, and 50%, respectively

• The clinical benefit rates in the imlunestrant alone, imlunestrant + everolimus, and imlunestrant + alpelisib groups were 42%, 62%, and 62%, respectively

Investigators concluded that imlunestrant used alone or in combination with 1 of the 2 kinase inhibitors demonstrated robust efficacy in individuals with pretreated, ER-positive, HER2-negative advanced breast cancer. 

OPERA: OP-1250 Paired With a CDK4/6 Inhibitor: Anti-Tumor Activity With No Dose-Limiting Toxicities

Study synopsis

OP-1250, a CERAN and SERD, continues to show promising results when paired with a CDK4/6 inhibitor. The combination of OP-1250 and the CDK4/6 inhibitor palbociclib appears to be well tolerated and has a similar safety profile to each drug when used alone, according to a phase I/II study involving 20 individuals with pretreated ER-positive, HER2-negative breast cancer.

Participants had advanced or metastatic ER-positive, HER2-negative breast cancer that progressed on ≤1 lines of endocrine therapy. Fourteen participants had received prior CDK4/6 inhibitor therapy, including 11 who were previously treated with palbociclib. Patients received escalating doses of OP-1250 with 125 mg of palbociclib orally daily for 21 of 28 days. OP-1250 doses were 30 mg (n=3), 60 mg (n=3), 90 mg (n=3), and 120 mg (n=11). Investigators assessed pharmacokinetics, drug-drug interactions, safety, and efficacy. Among the results observed to date: 

• Grade 3 neutropenia occurred in 55% of participants

• There were no grade 4 treatment-related adverse events and no dose-limiting toxicities

• OP-1250 exposure yielded similar results to what was seen in the previous monotherapy study

• Palbociclib exposure was comparable to published monotherapy data when combined with OP-1250 for all dosages

• Investigators observed antitumor activity, including partial responses

Researchers concluded that OP-1250 does not affect the pharmacokinetics of palbociclib, and there do not appear to be drug-drug interactions. Tumor response to this combination was encouraging and requires continued investigation. 

Conclusions

These 3 studies presented at ESMO 2023 highlight exciting novel therapies for the treatment of HR-positive, HER2-low, and HER2-negative metastatic breast cancer. The EMBER and OPERA updates provide support for the safety and efficacy of these novel endocrine agents in combination with kinase inhibitors and CDK4/6 inhibitors, respectively, in patients with endocrine-sensitive disease, while the TROPION-01 study demonstrates the encouraging efficacy and safety of a second TROP-2-directed ADC in a more heavily pretreated population.

December marks the advent of the approval of tirzepatide (Zepbound) for on-label treatment of obesity. In November 2023, the US Food and Drug Administration (FDA) approved it for the treatment of obesity in adults.

In May 2022, the FDA approved Mounjaro, which is tirzepatide, for type 2 diabetes. Since then, many physicians, including myself, have prescribed it off-label for obesity. As an endocrinologist treating both obesity and diabetes, I am sharing some lessons learned (many from my patients) on how best to prescribe tirzepatide.

The Expertise

Because GLP-1 receptor agonists have been around since 2005, we’ve had over a decade of clinical experience with these medications. Table 2 provides more nuanced information on tirzepatide (as Zepbound, for obesity) based on our experiences with dulaglutide, liraglutide, semaglutide, and tirzepatide (as Mounjaro).

166298_table2_web.jpg

The Reality

In today’s increasingly complex healthcare system, the reality of providing high-quality obesity care is challenging. When discussing tirzepatide with patients, I use a 4 Cs schematic — comorbidities, cautions, costs, choices — to cover the most frequently asked questions.

Comorbidities

In trials, tirzepatide reduced A1c by about 2%. In one diabetes trial, tirzepatide reduced liver fat content significantly more than the comparator (insulin), and trials of tirzepatide in nonalcoholic steatohepatitis are ongoing. A prespecified meta-analysis of tirzepatide and cardiovascular disease estimated a 20% reduction in the risk for cardiovascular death, myocardial infarction, stroke, and hospitalized unstable angina. Tirzepatide as well as other GLP-1 agonists may be beneficial in alcohol use disorder. Prescribing tirzepatide to patients who have or are at risk of developing such comorbidities is an ideal way to target multiple metabolic diseases with one agent.

Cautions

The first principle of medicine is “do no harm.” Tirzepatide may be a poor option for individuals with a history of pancreatitis, gastroparesis, or severe gastroesophageal reflux disease. Because tirzepatide may interfere with the efficacy of estrogen-containing contraceptives during its uptitration phase, women should speak with their doctors about appropriate birth control options (eg, progestin-only, barrier methods). In clinical trials of tirzepatide, male participants were also advised to use reliable contraception. If patients are family-planning, tirzepatide should be discontinued 2 months (for women) and 4 months (for men) before conception, because its effects on fertility or pregnancy are currently unknown.

Costs

At a retail price of $1279 per month, Zepbound is only slightly more affordable than its main competitor, Wegovy (semaglutide 2.4 mg). Complex pharmacy negotiations may reduce this cost, but even with rebates, coupons, and commercial insurance, these costs still place tirzepatide out of reach for many patients. For patients who cannot access tirzepatide, clinicians should discuss more cost-feasible, evidence-based alternatives: for example, phentermine, phentermine-topiramate, naltrexone-bupropion, metformin, bupropion, or topiramate.

Choices

Patient preference drives much of today’s clinical decision-making. Some patients may be switching from semaglutide to tirzepatide, whether by choice or on the basis of physician recommendation. Although no head-to-head obesity trial exists, data from SURPASS-2 and SUSTAIN-FORTE can inform therapeutic equivalence:

• Semaglutide 1.0 mg to tirzepatide 2.5 mg will be a step-down; 5 mg will be a step-up
• Semaglutide 2.0 or 2.4 mg to tirzepatide 5 mg is probably equivalent

The decision to switch therapeutics may depend on weight loss goals, side effect tolerability, or insurance coverage. As with all medications, the use of tirzepatide should progress with shared decision-making, thorough discussions of risks vs benefits, and individualized regimens tailored to each patient’s needs.

The newly approved Zepbound is a valuable addition to our toolbox of obesity treatments. Patients and providers alike are excited for its potential as a highly effective antiobesity medication that can cause a degree of weight loss necessary to reverse comorbidities. The medical management of obesity with agents like tirzepatide holds great promise in addressing today’s obesity epidemic.

December marks the advent of the approval of tirzepatide (Zepbound) for on-label treatment of obesity. In November 2023, the US Food and Drug Administration (FDA) approved it for the treatment of obesity in adults.

In May 2022, the FDA approved Mounjaro, which is tirzepatide, for type 2 diabetes. Since then, many physicians, including myself, have prescribed it off-label for obesity. As an endocrinologist treating both obesity and diabetes, I am sharing some lessons learned (many from my patients) on how best to prescribe tirzepatide.

The Expertise

Because GLP-1 receptor agonists have been around since 2005, we’ve had over a decade of clinical experience with these medications. Table 2 provides more nuanced information on tirzepatide (as Zepbound, for obesity) based on our experiences with dulaglutide, liraglutide, semaglutide, and tirzepatide (as Mounjaro).

With the growing number of treatment options for psoriatic arthritis (PsA), therapeutic decision-making has shifted to an increasingly tailored and patient-centered approach. A number of factors contribute to the treatment decision-making process, including age, insurance restrictions, route of administration, side effect profile, comorbidities, and extra-articular manifestations of the disease. In this article, we discuss an extra-articular comorbidity, uveitis, which is frequently seen in patients with PsA. We discuss clinical characteristics of uveitis associated with PsA and describe how the presence of uveitis influences our treatment approach to PsA, based on existing data.

Uveitis refers broadly to inflammation of the uvea, the vascularized and pigmented layer of the eye composed of the iris, the ciliary body, and the choroid. While infection is a common cause of uveitis, many cases are noninfectious and are often associated with an underlying autoimmune or systemic inflammatory disorder. Uveitis is frequently reported in diseases in the spondyloarthritis (SpA) family, including axial spondyloarthritis (AxSpA) and reactive arthritis, as well as PsA. Exact estimates of the prevalence of uveitis in PsA vary widely from 7%-25%, depending on the particular cohort studied.^1,2 In all forms of SpA, the anterior chamber of the uvea is the most likely to be affected.³ However, compared to patients with AxSpA, patients with PsA appear to have a higher rate of posterior involvement. In addition, patients with PsA appear to have higher frequencies of insidious, bilateral uveitis, as compared to the acute, unilateral, anterior uveitis that is most characteristic of AxSpA.⁴ Women with PsA may be more likely than men to experience uveitis, although this has not been a consistent finding.⁵ 

Patients with PsA who are human leukocyte antigen B27 (HLA-B27) positive may be at risk for more severe and refractory anterior uveitis compared to those who do not express the allele.⁵ Those who are HLA-B27 positive are also known to have higher rates of axial involvement. It has therefore been postulated that 2 phenotypes of uveitis may exist in PsA: patients who are HLA-B27 positive who have axial disease and severe, unilateral anterior uveitis reminiscent of other forms of SpA, and patients who are HLA-B27 negative, often women, with peripheral-predominant arthritis who are prone to the classic anterior uveitis but may also develop atypical bilateral, insidious, and/or posterior involvement.⁴ Specific characteristics of PsA may also provide information about the risk for developing uveitis. For example, dactylitis has been linked to a higher risk of developing uveitis in some, but not all, cohorts of patients with PsA, and the risk of uveitis in PsA has been found in many studies to correlate with longer duration of disease.^6-8

The presence of uveitis signals a disruption in the blood-retina barrier and the subsequent entrance of inflammatory cells into the eye. An entire explanation of pathogenesis is beyond the scope of this article; however, it is worth noting that many of the inflammatory mediators of active uveitis mirror those of PsA. For instance, both the mesenchymal cells in enthesitis and the cells of the ciliary body express receptors for interleukin (IL)-23, suggesting a potential role of the signaling pathways involving this cytokine in both diseases.⁹ Another study found increased serum levels of IL-17, a known mediator of PsA disease, in patients with active uveitis.¹⁰ Despite these common pathogenesis links, there are limited data on the utility of certain existing PsA treatments on uveitis manifestations.

Our approach is always to manage uveitis associated with PsA in collaboration with a specialized and experienced ophthalmologist. Uncontrolled uveitis can be vision threatening and contribute to long-term morbidity associated with PsA, so timely recognition, evaluation, and appropriate treatment are important. Ocular glucocorticoid (GC) drops may be used as first-line therapy, particularly for anterior uveitis, to quickly quell inflammation. Escalation to systemic GCs for more severe or posteriorly localized disease may be considered carefully, given the known risk of worsening skin psoriasis (PsO) with GC withdrawal after a course of therapy. Use of GC-sparing therapy should be determined on a case-by-case basis. While generalized, noninfectious uveitis often resolves with GC treatment, the risk of uveitis recurrence in patients with PsA and the challenges of systemic GCs with PsO lead us to frequently consider GC-sparing therapy that addresses ocular, musculoskeletal, and cutaneous manifestations. Tumor necrosis factor inhibitors (TNF-I) are our typical first-line considerations for GC-sparing therapy in patients with PsA with inflammatory joint symptoms and uveitis, although nonbiologic therapy can be considered first-line therapy in select populations.

Data establishing the efficacy of TNF-I come largely from randomized controlled trials (RCTs) of adalimumab (ADA) compared to placebo in noninfectious uveitis.¹¹ While these trials focused on idiopathic posterior or pan-uveitis, these data have been extrapolated to SpA-associated anterior uveitis, and large registry analyses have supported use of TNF-I in this population.¹² When selecting a particular TNF-I in a patient with current or past uveitis, we frequently start with ADA, based on supportive, albeit uncontrolled, data suggesting a reduction in the risk of recurrence with this agent in patients with SpA and uveitis.¹² For patients who are unable to tolerate subcutaneous injections, who fail ADA, or who we suspect will require higher, titratable dosing, we favor infliximab infusions. Other data suggest that golimumab and certolizumab are also reasonable alternatives.^13,14 We do not generally use etanercept, as the limited data that are available suggest that it is less effective at reducing risk of uveitis recurrence.¹² Methotrexate or leflunomide may be an appropriate first line choice for patients with peripheral-predominant PsA and uveitis, but it is important to note that these agents are not effective for axial disease.

Despite the mechanistic data implicating the role of IL-17 in uveitis associated with PsA, the IL-17A inhibitor, secukinumab, failed to show a reduction in uveitis recurrence, compared to placebo, in pooled analysis of RCTs of noninfectious uveitis.¹⁵ However, a phase 2 trial of intravenous secukinumab in noninfectious uveitis showed promise, possibly because this dosing regimen can achieve higher effective concentrations.¹⁶ It is not our current practice to use secukinumab or ixekizumab as a first-line therapy in patients with PsA and concurrent uveitis, owing to a lack of data supporting efficacy. A novel IL-17A/F inhibitor, bimekizumab (BKZ), has recently been used in several successful phase 3 trials in patients with both TNF-naïve and TNF-nonresponder SpA, including AxSpA and PsA.¹⁷ Interestingly, data from the phase 2 and 3 trials of BKZ found low incidence rates of uveitis in patients with SpA treated with BKZ compared to placebo, suggesting that BKZ might be more effective in uveitis than other IL-17 inhibitors, but these data need to be confirmed.

Successful use of Janus kinase (JAK) inhibitors in noninfectious uveitis, including cases associated with inflammatory arthritis, has been described in case reports as well as in current phase 2 trials.¹⁸ The dual IL-12/IL-23 inhibitor, ustekinumab, also showed initial promise in a small, nonrandomized, uncontrolled phase 1/2 study of the treatment of posterior uveitis, as well as success in few case reports of PsA-associated uveitis.¹⁹ However, a post-hoc analysis of extra-intestinal manifestations, including uveitis and iritis, in patients with inflammatory bowel disease treated with ustekinumab found no benefit in preventing or treating ocular disease compared to placebo.²⁰ Given the paucity of available data, JAK inhibitors and the IL-12/IL-23 inhibitor, ustekinumab, are not part of our typical treatment algorithm for patients with PsA-associated uveitis.

In conclusion, uveitis is a frequent extra-articular comorbidity of PsA, and it may present differently than the typical acute onset, unilateral anterior uveitis seen in SpA. While uveitis may share many different immunologic threads with PsA, the most convincing data support the use of TNF-I as a GC-sparing agent in this setting, particularly ADA, infliximab, golimumab, or certolizumab. Our approach is generally to start with these agents or methotrexate when directed therapy is needed for uveitis in PsA. Further investigation into the use of the IL-17A/F inhibitor BKZ and JAK inhibitors, as well as tyrosine kinase 2 inhibitors, in PsA associated uveitis may yield additional options for our patients.²¹

Tumor necrosis factor inhibitors (TNF-I) are our typical first-line considerations for GC-sparing therapy in patients with PsA with inflammatory joint symptoms and uveitis, although nonbiologic therapy can be considered first-line therapy in select populations.

Data establishing the efficacy of TNF-I come largely from randomized controlled trials (RCTs) of adalimumab (ADA) compared to placebo in noninfectious uveitis.¹¹ While these trials focused on idiopathic posterior or pan-uveitis, these data have been extrapolated to SpA-associated anterior uveitis, and large registry analyses have supported use of TNF-I in this population.¹² When selecting a particular TNF-I in a patient with current or past uveitis, we frequently start with ADA, based on supportive, albeit uncontrolled, data suggesting a reduction in the risk of recurrence with this agent in patients with SpA and uveitis.¹² For patients who are unable to tolerate subcutaneous injections, who fail ADA, or who we suspect will require higher, titratable dosing, we favor infliximab infusions. Other data suggest that golimumab and certolizumab are also reasonable alternatives.^13,14 We do not generally use etanercept, as the limited data that are available suggest that it is less effective at reducing risk of uveitis recurrence.¹² Methotrexate or leflunomide may be an appropriate first line choice for patients with peripheral-predominant PsA and uveitis, but it is important to note that these agents are not effective for axial disease.

Despite the mechanistic data implicating the role of IL-17 in uveitis associated with PsA, the IL-17A inhibitor, secukinumab, failed to show a reduction in uveitis recurrence, compared to placebo, in pooled analysis of RCTs of noninfectious uveitis.¹⁵ However, a phase 2 trial of intravenous secukinumab in noninfectious uveitis showed promise, possibly because this dosing regimen can achieve higher effective concentrations.¹⁶ It is not our current practice to use secukinumab or ixekizumab as a first-line therapy in patients with PsA and concurrent uveitis, owing to a lack of data supporting efficacy. A novel IL-17A/F inhibitor, bimekizumab (BKZ), has recently been used in several successful phase 3 trials in patients with both TNF-naïve and TNF-nonresponder SpA, including AxSpA and PsA.¹⁷ Interestingly, data from the phase 2 and 3 trials of BKZ found low incidence rates of uveitis in patients with SpA treated with BKZ compared to placebo, suggesting that BKZ might be more effective in uveitis than other IL-17 inhibitors, but these data need to be confirmed.

Successful use of Janus kinase (JAK) inhibitors in noninfectious uveitis, including cases associated with inflammatory arthritis, has been described in case reports as well as in current phase 2 trials.¹⁸ The dual IL-12/IL-23 inhibitor, ustekinumab, also showed initial promise in a small, nonrandomized, uncontrolled phase 1/2 study of the treatment of posterior uveitis, as well as success in few case reports of PsA-associated uveitis.¹⁹ However, a post-hoc analysis of extra-intestinal manifestations, including uveitis and iritis, in patients with inflammatory bowel disease treated with ustekinumab found no benefit in preventing or treating ocular disease compared to placebo.²⁰ Given the paucity of available data, JAK inhibitors and the IL-12/IL-23 inhibitor, ustekinumab, are not part of our typical treatment algorithm for patients with PsA-associated uveitis.

In conclusion, uveitis is a frequent extra-articular comorbidity of PsA, and it may present differently than the typical acute onset, unilateral anterior uveitis seen in SpA. While uveitis may share many different immunologic threads with PsA, the most convincing data support the use of TNF-I as a GC-sparing agent in this setting, particularly ADA, infliximab, golimumab, or certolizumab. Our approach is generally to start with these agents or methotrexate when directed therapy is needed for uveitis in PsA. Further investigation into the use of the IL-17A/F inhibitor BKZ and JAK inhibitors, as well as tyrosine kinase 2 inhibitors, in PsA associated uveitis may yield additional options for our patients.²¹
