Rheumatology

LIVERPOOL, ENGLAND — The British Society for Rheumatology (BSR) and the British Association of Dermatologists (BAD) have joined forces for the first time to develop the first British guidelines for the management of people living with Behçet’s disease.

The guidelines will also be the first “living guidelines” produced by either society, which means they will be regularly revised and updated when new evidence emerges that warrants inclusion.

With more than 90 recommendations being made, the new guidelines promise to be the most comprehensive and most up-to-date yet for what is regarded as a rare disease. Robert Moots, MBBS, PhD, provided a “sneak peek” of the guidelines at the annual meeting of the British Society for Rheumatology.

Dr. Moots, professor of rheumatology at the University of Liverpool and a consultant rheumatologist for Liverpool University Hospitals NHS Foundation Trust in England, noted that while the European Alliance of Associations for Rheumatology has produced a guideline for Behçet’s disease, this was last updated in 2018 and is not specific for the population for patients that is seen in the United Kingdom.

The British recommendations will cover all possible manifestations of Behçet’s disease and give practical advice on how to manage everything from the most common presentations such as skin lesions, mouth ulcers, and genital ulcers, as well as the potentially more serious eye, neurological, and vascular involvement.

Importance of Raising Awareness

“Joint and musculoskeletal problems are actually one of the least complained of symptoms in people with Behçet’s, and they often can’t understand why a rheumatologist is seeing them,” Dr. Moot said. “But of course, people do get joint problems, they can get enthesitis and arthralgia.”

Dr. Moots has been leading one of the three National Health Service (NHS) Centres of Excellence for Behçet’s Syndrome in England for more than a decade and told this news organization that diagnosing patients could be challenging. It can take up to 10 years from the first symptoms appearing to getting a diagnosis, so part of the job of the NHS Centres of Excellence is to raise awareness among both the healthcare profession and the general public.

“It’s a condition that people learn about at medical school. Most doctors will have come across it, but because it was thought to be really rare in the UK, nobody perhaps really expects to see it,” Dr. Moot said.

“But we all have these patients,” he added. “In Liverpool, we’re commissioned to be looking after an anticipated 150 people with Behçet’s — we’ve got 700. With more awareness, there’s more diagnoses being made, and people are being looked after better.”
 

Patient Perspective

Tony Thornburn, OBE, chair of the patient advocacy group Behçet’s UK, agreed in a separate interview that raising awareness of the syndrome was key to improving its management.

“Patients have said that it is a bit like having arthritis, lupus, MS [multiple sclerosis], and Crohn’s [disease] all at once,” Mr. Thorburn said. “So what we need is a guideline to ensure that people know what they’re looking at.”

Mr. Thorburn added, “Guidelines are important for raising awareness but also providing the detailed information that clinicians and GPs [general practitioners] need to have to treat a patient when they come in with this multifaceted condition.”
 

Multifaceted Means Multidisciplinary Management

Because there can be so many different aspects to managing someone with Behçet’s disease, a multispecialty team that was convened to develop the guidelines agreed that multidisciplinary management should be an overarching theme.

“The guideline development group consisted of all the specialties that you would need for a complex multisystem disease like Behçet’s,” Dr. Moot said. He highlighted that working alongside the consultants in adult and pediatric rheumatology were specialists in dermatology, gastroenterology, neurology, ophthalmology, obstetrics and gynecology, and psychology.

“We’re actually looking at psychological interactions and their impact for the first time,” Dr. Moot said, noting that clinicians needed to “take it seriously, and ask about it.”
 

Management of Manifestations

One of the general principles of the guidelines is to assess the involvement of each organ system and target treatment accordingly.

“One of the problems is that the evidence base to tell us what to do is pretty low,” Dr. Moots acknowledged. There have been few good quality randomized trials, so “treatment tends to be eminence-based rather than evidence-based.”

The recommendation wording bears this in mind, stating whether a treatment should or should not be offered, or just considered if there is no strong evidence to back up its use.

With regard to musculoskeletal manifestations, the recommendations say that colchicine should be offered, perhaps as a first-line option, or an intraarticular steroid injection in the case of monoarthritis. An intramuscular depot steroid may also be appropriate to offer, and there was good evidence to offer azathioprine or, as an alternative in refractory cases, a tumor necrosis factor (TNF) inhibitor. Nonsteroidal anti-inflammatory drugs, methotrexate, apremilast, secukinumab, and referral to a physiotherapist could only be considered, however, based on weaker levels of evidence for their use.

To treat mucocutaneous disease, the guidelines advise offering topical steroids in the form of ointment for genital ulcers or mouthwash or ointment for oral ulcers. For skin lesions, it is recommended to offer colchicine, azathioprine, mycophenolate mofetil, or TNF inhibitor and to consider the use of apremilast, secukinumab, or dapsone.
 

Future Work and Revision

“One of the key things we would like to see developing is a national registry,” Dr. Moots said. This would include biobanking samples for future research and possible genomic and phenotyping studies.

More work needs to be done in conducting clinical trials in children and young people with Behçet’s disease, studies to find prognostic factors for neurological disease, and clinical trials of potential new drug approaches such as Janus kinase inhibitors. Importantly, an auditing process needs to be set up to see what effect, if any, the guidelines will actually have onpatient management.

“It’s taken 5 years to today” to develop the guidelines, Dr. Moot said. What form the process of updating them will take still has to be decided, he said in the interview. It is likely that the necessary literature searches will be performed every 6 months or so, but it will be a compromise between the ideal situation and having the staffing time to do it.

“It’s a big ask,” Dr. Moot acknowledged, adding that even if updates were only once a year, it would still be much faster than the 5- or 6-year cycle that it traditionally takes for most guidelines to be updated.

The BSR and BAD’s processes for developing guidelines are accredited by the National Institute for Health and Care Excellence in England. Dr. Moots is the chief investigator for the Secukinumab in Behçet’s trial, which is sponsored by the Liverpool University Hospitals NHS Foundation Trust via grant funding from Novartis.

Inflammatory arthritis codes increased 30-fold in the transition from the ninth to the 10th revision of the International Classification of Diseases (ICD-9 and -10), yet few were used in clinical practice, according to new research.

Most of the new codes for inflammatory arthritis in ICD-10 were rarely used, if at all, from 2015 to 2021.

“About 10-20 codes were comprising the majority of usage for inflammatory arthritis patients in ICD-10,” first author Justin Zhu, a researcher and medical student at Yale University in New Haven, Connecticut, told this news organization. “The other 380 or 400 codes just weren’t seeing a lot of use.”

Zhu_Justin_CT_web.jpg

The findings show the difficulties of transitioning to a new system, he added, and emphasize the need for additional training to improve adoption of ICD-11. The new coding system launched globally in January 2022, but it is not clear when it will be implemented in the United States.

ICD-10 was launched in the United States in 2015, with the goal of enabling greater specificity in identifying health conditions. For example, the new coding system allowed users to include information on laterality and anatomic location for the first time. The total number of codes increased from 14,500 with ICD-9 to 70,000 with ICD-10, with the number of inflammatory arthritis diagnosis codes growing from 14 to 425.

To see how these ICD-10 codes were utilized compared with ICD-9, Zhu and colleagues used national multi-insurance administrative claims data to find inflammatory arthritis diagnostic codes for over 5.1 million patients. About half were coded in ICD-9, while the remaining half were coded in ICD-10. Mr. Zhu and colleagues defined “higher-usage codes” as those that were used more than 1% of the time.

The findings were published in a research letter in JAMA Network Open on April 18.

For ICD-9, four of the available 14 codes (28.6%) were higher-usage codes. In contrast, only nine of the 425 ICD-10 codes (2.1%) were frequently used. Though ICD-10 allowed for increased granularity in diagnosis, data showed that nonspecific codes were most popular. Of the 20 most used ICD-10 arthritis codes, 65% contained “unspecified or other specified” in its wording.

The researchers also found that there was no significant change in these higher-usage codes throughout the study period from 2015 to 2021, suggesting there was not a detectable learning curve in ICD-10 usage among physicians and coders. They also found that clinician specialty did not change code usage patterns.

“The percentage of codes used was not better for rheumatologists (who might be expected to be more refined users of such codes) than primary care clinicians,” Mr. Zhu and colleagues wrote.
 

Moving to ICD-11 Brings Challenges as Well as Opportunities

Mr. Zhu noted that the study highlights the challenges of adopting new technological systems into daily practice, which can inform the eventual transition to ICD-11.

“There is this need to emphasize training as well as just invest more in improving adoption of ICD-11,” he said.

Michael Pine, MD, MBA, of MJP Healthcare Innovations, LLC in Evanston, Illinois, added that ICD-11 needs to be more user-friendly to be useful in practice. While ICD-10 allowed for greater granularity in coding, it did not result in “usable granularity, in terms of the things doctors really want to communicate,” he told this news organization.

And the transition to ICD-11 could pose greater challenges; rather than ICD-10’s taxonomy system, ICD-11 is formatted as an ontology.

VIENNA — The glucagon-like peptide 1 (GLP-1) receptor agonist semaglutide (Wegovy) not only induced weight loss but also improved knee pain in people with knee osteoarthritis (OA) and obesity, according to results from the STEP 9 study reported at the Osteoarthritis Research Society International (OARSI) 2024  World Congress.

From baseline to week 68, the mean change in knee pain assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain score was a reduction of 41.7 points for semaglutide and a decrease of 27.5 points for a matching placebo. The estimated treatment difference of 14.1 points between the groups was statistically significant (P < .001).

As for weight loss, this also fell by a significantly greater amount in the people treated with semaglutide vs those given placebo, with respective reductions of 13.7% and 3.2% from baseline, with an estimated 10.5% greater weight loss with semaglutide.

167824_Bliddal_Henning_web.jpg

“The interesting thing is whether there’s a specific action of GLP-1 receptor agonists on the joint, not through the weight loss but by itself,” principal study investigator Henning Bliddal, MD, DMSc, told this news organization ahead of reporting the results at OARSI 2024.

Weight loss is “obviously good” because “the knees suffer from the weight. But whether it’s good for the knee or just for the health or the well-being of the person is another matter,” said Dr. Bliddal, who is director of the Parker Institute at Bispebjerg Frederiksberg Hospital in Copenhagen, Denmark.
 

Not Approved in OA

Semaglutide and other potentially weight loss-inducing drugs are not currently indicated for use specifically in OA, Tonia Vincent, MBBS, PhD, told this news organization, and so “I think we have to be very cautious,” she said.

“Weight loss is one of the few things that has been shown to be successful in clinical trials,” said Dr. Vincent, who is a professor of musculoskeletal biology and an honorary rheumatologist at the Kennedy Institute of Rheumatology at Oxford University in Oxford, England.

“People always feel better too when they lose weight, so that helps manage pain. So, I’d be very surprised if there isn’t a benefit,” she added.

“I just think we need to know more about the long-term use of these drugs, whether the healthcare system can afford them, and how we would ration them.”

The STEP 9 study is not the first time that Dr. Bliddal has investigated the effects of a GLP-1 receptor agonist in people with knee OA, but it is the first to have shown a significant effect on knee pain.

Previously, results from the LOSEIT trial with liraglutide demonstrated that, after an 8-week dietary intervention run-in phase, people who were treated with the GLP-1 receptor agonist lost an average of 2.8 kg in body weight over a period of 1 year, vs a 1.2 kg gain in the placebo group. Knee injury and Osteoarthritis Outcome Scores, however, were largely unaffected.

“The study was more or less negative for knee pain because at that time we had to pretreat patients with some kind of weight loss before they were allowed to have the liraglutide,” Dr. Bliddal said.

“There’s so many different considerations with diets and the different ways that [dietary modification] is performed, that could be part of the explanation why some people didn’t find the pain relief,” Dr. Bliddal suggested.
 

STEP 9 Study Design

No pre-study dietary intervention was required in the STEP 9 trial, although a reduced-calorie diet and increased physical exercise were used alongside both semaglutide and placebo treatment.

STEP 9 was a multicenter, multinational phase 3 clinical trial that enrolled people if they had a body mass index (BMI) of > 30, had a clinical diagnosis of knee OA with moderate radiographic changes (Kellgren-Lawrence grade of 2-3), and were experiencing knee pain.

In addition to a baseline WOMAC pain score of at least 40 points (where 0 represents no and 100 the worst pain), the participants had to have a WOMAC numerical rating scale (NRS) score of ≥ 3.1.

A total of 407 participants were recruited and randomly allocated, 2:1, to receive once-weekly subcutaneous injections of either semaglutide 2.4 mg or placebo for a total of 68 weeks.

Dr. Bliddal presented demographic information only for the study population as a whole, showing that the mean was 56 years, 81.6% were women, 60.9% were White, 11.8% Native American, 7.6% Black, and 19.7% of other ethnic origin.

Moreover, the mean bodyweight at baseline was 108.6 kg, and the mean baseline BMI was 40.3, with 75% of participants having a BMI ≥ 35. The mean waist circumference was 118.7 cm. The mean baseline WOMAC pain score was 70.9.
 

Other Findings

In addition to the reductions seen in the coprimary endpoints of weight loss and knee pain, the WOMAC physical function score was also reduced from baseline to week 68 to a greater degree in the semaglutide than placebo arm, by a respective 41.5 vs 26.7 points, with a significant estimated treatment difference of -14.9 points.

“The use of pain medication went down as well; you can see the drop was faster in the semaglutide group than the placebo group, and it was maintained throughout the study,” Dr. Bliddal said during his presentation. He noted that patients had to temporarily stop taking pain relievers such as acetaminophen 3 days before their pain was assessed.

Additional findings reported in the abstract, but not presented at the meeting, were a significant estimated treatment difference of -1.0 in NRS pain intensity, more people treated with semaglutide than placebo achieving ≥ 5% (87.0% vs 29.2%) or ≥ 10% (70.4% vs 9.2%) weight loss.

“Safety and tolerability with semaglutide were consistent with the global STEP program and the GLP-1 receptor agonist class in general,” Dr. Bliddal reported.

Serious adverse events occurred in a respective 10.0% and 8.1% of participants, and adverse events leading to discontinuation were recorded in 6.7% and 3%. Around one third (2.2%) of those leading to discontinuation in the semaglutide arm were gastrointestinal adverse events.

The STEP 9 study was funded by Novo Nordisk. Henning is a principal investigator for the trial and acknowledged that research grants were received from Novo Nordisk to his institution, as well as consulting fees and honoraria. He has also received congress and travel support from Contura. Dr. Vincent was not involved in the study and had no relevant conflicts of interest to disclose.

VIENNA — The glucagon-like peptide 1 (GLP-1) receptor agonist semaglutide (Wegovy) not only induced weight loss but also improved knee pain in people with knee osteoarthritis (OA) and obesity, according to results from the STEP 9 study reported at the Osteoarthritis Research Society International (OARSI) 2024  World Congress.

From baseline to week 68, the mean change in knee pain assessed using the Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain score was a reduction of 41.7 points for semaglutide and a decrease of 27.5 points for a matching placebo. The estimated treatment difference of 14.1 points between the groups was statistically significant (P < .001).

As for weight loss, this also fell by a significantly greater amount in the people treated with semaglutide vs those given placebo, with respective reductions of 13.7% and 3.2% from baseline, with an estimated 10.5% greater weight loss with semaglutide.

“The interesting thing is whether there’s a specific action of GLP-1 receptor agonists on the joint, not through the weight loss but by itself,” principal study investigator Henning Bliddal, MD, DMSc, told this news organization ahead of reporting the results at OARSI 2024.

Weight loss is “obviously good” because “the knees suffer from the weight. But whether it’s good for the knee or just for the health or the well-being of the person is another matter,” said Dr. Bliddal, who is director of the Parker Institute at Bispebjerg Frederiksberg Hospital in Copenhagen, Denmark.
 

Not Approved in OA

Semaglutide and other potentially weight loss-inducing drugs are not currently indicated for use specifically in OA, Tonia Vincent, MBBS, PhD, told this news organization, and so “I think we have to be very cautious,” she said.

“Weight loss is one of the few things that has been shown to be successful in clinical trials,” said Dr. Vincent, who is a professor of musculoskeletal biology and an honorary rheumatologist at the Kennedy Institute of Rheumatology at Oxford University in Oxford, England.

“People always feel better too when they lose weight, so that helps manage pain. So, I’d be very surprised if there isn’t a benefit,” she added.

“I just think we need to know more about the long-term use of these drugs, whether the healthcare system can afford them, and how we would ration them.”

Patient-reported outcomes (PROs) in rheumatology are not just personal lists of physical complaints or so-called “organ recitals.” In fact, PROs can both guide treatment decisions in daily practice and serve as key endpoints for clinical trials.

That’s the informed opinion of Clifton O. Bingham III, MD, director of the Johns Arthritis Center in Baltimore, Maryland, who discussed clinical and research applications of PROs at the 2024 Rheumatoid Arthritis Research Summit presented by the Arthritis Foundation and the Hospital for Special Surgery in New York City.

Bingham_Clifton_O_MD_web.jpg

“Integrating PROs into practice settings can enhance the clinician’s ability to understand their patients and monitor disease impact, and they are increasingly available for clinical care and are being qualified for outcome measures for clinical trials,” Dr. Bingham said.

“I posit to you that some of this ability to better characterize things like anxiety and depression levels of patients more precisely may help us to identify those patients who are less likely to respond to therapy and may require different interventions than disease-modifying therapies for their disease,” he told the audience.
 

PRO Examples

The term PRO encompasses a broad range of measures that may include health-related quality of life measures, symptoms and their affects, patient satisfaction, and the patient’s experience with care.

PROs are important for rheumatology care and research because “we now have the capacity to make what we used to think were the subjective experiences of disease more objective. We now have ways that we can put numbers and measurements to the experiences that patients have about their illness and use that information as a way to understand more about the patients who are in front of us and also how their disease changes over time,” Dr. Bingham said.

Patients are the best — or in some cases, the only — judges of many aspects of their health, and they are best suited to report on certain events and outcomes, he said.

PROs that are currently included in core outcome measures used to guide care and in clinical trials in pain scores as reported by visual analog scales; functioning, as measured by the Health Assessment Questionnaire-Disability Index (HAQ-DI); and patient global assessment.

In international qualitative studies in which patients with rheumatoid arthritis (RA) were asked what was most important to them, the usual suspects of pain, function, and fatigue were routinely cited across the studies. But patients in studies from these groups (RAPP-PI, RAID, and OMERACT) also said that other factors important to their well-being included good sleep, enjoyment of life, independence, ability to participate in valued activities, and freedom from emotional distress, Dr. Bingham noted.
 

The Promise of PROMIS

The science of clinical measurement has advanced dramatically during his career, as Dr. Bingham said.

“There have been significant changes in the science behind how you develop and validate outcomes measures. The fields of clinimetrics and psychometrics have evolved substantially. These are now grounded in what we call ‘modern measurement’ approaches, which focus on item-response theory, constructing interval scales of measurement in things that are very precise in their ability to detect change over time,” he said.

One such measurement instrument is the Patient-Reported Outcome Measurement Information System (PROMIS®), developed at the National Institutes of Health using advanced measurement science.

The system, administered through either computer or paper questionnaires, is designed to improve precision of health-related quality of life assessments in multiple domains, including most domains identified by patients with RA. It uses a T-score metric standardized to the US population.

“You can use this in a disease like rheumatoid arthritis, and you can find out how patients are doing in reference to the normative United States populations,” he said.

Dr. Bingham noted that his team has “very good data” to show that PROMIS system significantly outperforms existing instruments such as the HAQ.
 

How It Works

The system uses item banks, each with multiple items. For example, there are approximately 150 items for the physical function assessment portion. All the items are scored along a continuum, “from people who are completely disabled to those who can run marathons,” Dr. Bingham said.

Each item on the scale has a question and response component, ranging from “are you able to get in and out of bed?” to “are you able to walk from one room to another?” to “are you able to run 5 miles?”

To evaluate the PROMIS scale, Dr. Bingham and colleagues looked at the distribution of PROMIS T-scores for 1029 patients with RA at their center. The scales showed that patients with RA have higher levels of pain, fatigue, and sleep disturbances, as well as worse physical function, than population norms.

Dr. Bingham and colleagues also evaluated the performance of the system in patients with active RA who were starting on or switching to a different disease-modifying antirheumatic drug (DMARD). As they reported in 2019, among 106 participants who completed the 12-week study, all PROMIS scores improved after DMARD initiation (P ≤ .05). In addition, except for the depression domain, changes in all assessed PROMIS measures correlated with changes in Clinical Disease Activity Index scores.

To see whether integrating PROs into routine clinics could have an effect on care, Dr. Bingham and colleagues conducted a prospective cohort study, which showed that with the additional patient-reported data, clinicians changed or adjusted RA treatment in 16%-19% of visits, identified new symptoms in 27%-38%, and suggested nonpharmacologic interventions in 4%-11%.

“This is information that’s being used, and it’s going into changing medical decision making,” he said.

Summarizing his work, Dr. Bingham told the audience “I hope that I have convinced you that patients with RA prioritize domains that are impacted by their disease. PROMIS measures are really state-of-the-science methods to evaluate multiple aspects of health-related quality of life, and what I’ll note to you is that these have been translated into multiple languages internationally. There are Spanish-language versions, there are Chinese language versions, there are versions for every country in the [European Union] that have been validated and can be used.”
 

It’s a Start

In the Q & A following the presentation, Daniel H. Solomon, MD, MPH, from Brigham and Women’s Hospital in Boston, commented that “the measurement issues and automating measurements seems like it’s a fundamental practice issue — how to manage the system and how to manage patients better, and I feel like we’re kind of scratching the surface.”

He said that artificial intelligence and PROs in clinic offer some promise for improving care but added that “we can do better than this. We can figure out better systems for measuring PROs: Having patients measure PROs, having patients tell us about their PROs so they don’t have to come in, or coming in only when they need to come in, when they’re really flaring. There are lots of innovative ways of thinking about these tools, and it feels like we’re kind of on the cusp of really taking advantage.”

Dr. Bingham’s work is supported by the Patient-Centered Outcomes Research Institute, National Institutes of Health, Ira T. Fine Discovery Fund, Johns Hopkins Arthritis Center Discovery Fund, Camille J. Morgan Arthritis Research and Education Fund, and Scheer Family Foundation and Joanne and John Rogers. He disclosed consulting for AbbVie, Janssen, Lilly, and Sanofi and serving as a board member of the PROMIS health organization, co-chair of the Omeract Technical Advisory Group, and member of the C-PATH RA PRO working group. Dr. Solomon had no relevant disclosures.

We now have ways that we can put numbers and measurements to the experiences that patients have about their illness and use that information as a way to understand more about the patients who are in front of us and also how their disease changes over time,” Dr. Bingham said.

Patients are the best — or in some cases, the only — judges of many aspects of their health, and they are best suited to report on certain events and outcomes, he said.

PROs that are currently included in core outcome measures used to guide care and in clinical trials in pain scores as reported by visual analog scales; functioning, as measured by the Health Assessment Questionnaire-Disability Index (HAQ-DI); and patient global assessment.

In international qualitative studies in which patients with rheumatoid arthritis (RA) were asked what was most important to them, the usual suspects of pain, function, and fatigue were routinely cited across the studies. But patients in studies from these groups (RAPP-PI, RAID, and OMERACT) also said that other factors important to their well-being included good sleep, enjoyment of life, independence, ability to participate in valued activities, and freedom from emotional distress, Dr. Bingham noted.
 

The Promise of PROMIS

The science of clinical measurement has advanced dramatically during his career, as Dr. Bingham said.

“There have been significant changes in the science behind how you develop and validate outcomes measures. The fields of clinimetrics and psychometrics have evolved substantially. These are now grounded in what we call ‘modern measurement’ approaches, which focus on item-response theory, constructing interval scales of measurement in things that are very precise in their ability to detect change over time,” he said.

One such measurement instrument is the Patient-Reported Outcome Measurement Information System (PROMIS®), developed at the National Institutes of Health using advanced measurement science.

The system, administered through either computer or paper questionnaires, is designed to improve precision of health-related quality of life assessments in multiple domains, including most domains identified by patients with RA. It uses a T-score metric standardized to the US population.

“You can use this in a disease like rheumatoid arthritis, and you can find out how patients are doing in reference to the normative United States populations,” he said.

Dr. Bingham noted that his team has “very good data” to show that PROMIS system significantly outperforms existing instruments such as the HAQ.
 

How It Works

The system uses item banks, each with multiple items. For example, there are approximately 150 items for the physical function assessment portion. All the items are scored along a continuum, “from people who are completely disabled to those who can run marathons,” Dr. Bingham said.

Each item on the scale has a question and response component, ranging from “are you able to get in and out of bed?” to “are you able to walk from one room to another?” to “are you able to run 5 miles?”

To evaluate the PROMIS scale, Dr. Bingham and colleagues looked at the distribution of PROMIS T-scores for 1029 patients with RA at their center. The scales showed that patients with RA have higher levels of pain, fatigue, and sleep disturbances, as well as worse physical function, than population norms.

Dr. Bingham and colleagues also evaluated the performance of the system in patients with active RA who were starting on or switching to a different disease-modifying antirheumatic drug (DMARD). As they reported in 2019, among 106 participants who completed the 12-week study, all PROMIS scores improved after DMARD initiation (P ≤ .05). In addition, except for the depression domain, changes in all assessed PROMIS measures correlated with changes in Clinical Disease Activity Index scores.

To see whether integrating PROs into routine clinics could have an effect on care, Dr. Bingham and colleagues conducted a prospective cohort study, which showed that with the additional patient-reported data, clinicians changed or adjusted RA treatment in 16%-19% of visits, identified new symptoms in 27%-38%, and suggested nonpharmacologic interventions in 4%-11%.

“This is information that’s being used, and it’s going into changing medical decision making,” he said.

Summarizing his work, Dr. Bingham told the audience “I hope that I have convinced you that patients with RA prioritize domains that are impacted by their disease. PROMIS measures are really state-of-the-science methods to evaluate multiple aspects of health-related quality of life, and what I’ll note to you is that these have been translated into multiple languages internationally. There are Spanish-language versions, there are Chinese language versions, there are versions for every country in the [European Union] that have been validated and can be used.”
 

It’s a Start

In the Q & A following the presentation, Daniel H. Solomon, MD, MPH, from Brigham and Women’s Hospital in Boston, commented that “the measurement issues and automating measurements seems like it’s a fundamental practice issue — how to manage the system and how to manage patients better, and I feel like we’re kind of scratching the surface.”

He said that artificial intelligence and PROs in clinic offer some promise for improving care but added that “we can do better than this. We can figure out better systems for measuring PROs: Having patients measure PROs, having patients tell us about their PROs so they don’t have to come in, or coming in only when they need to come in, when they’re really flaring. There are lots of innovative ways of thinking about these tools, and it feels like we’re kind of on the cusp of really taking advantage.”

Dr. Bingham’s work is supported by the Patient-Centered Outcomes Research Institute, National Institutes of Health, Ira T. Fine Discovery Fund, Johns Hopkins Arthritis Center Discovery Fund, Camille J. Morgan Arthritis Research and Education Fund, and Scheer Family Foundation and Joanne and John Rogers. He disclosed consulting for AbbVie, Janssen, Lilly, and Sanofi and serving as a board member of the PROMIS health organization, co-chair of the Omeract Technical Advisory Group, and member of the C-PATH RA PRO working group.

TOPLINE:

The time interval between onset of interstitial lung disease (ILD) and diagnosis of anti–melanoma differentiation-associated gene 5 (MDA5) antibody-positive dermatomyositis (DM) “has not been well described,” the authors say.

METHODOLOGY:

• MDA5 antibody-positive DM is a rare DM subtype associated with ILD, which is categorized into rapidly progressive ILD (RPILD) and chronic ILD, with the former having a particularly high mortality rate.
• In this retrospective cohort study using electronic medical records, researchers evaluated 774 patients with DM between 2008 and 2023 to learn more about the time interval between ILD and the time of an MDA5 antibody-positive DM diagnosis, which has not been well described.
• The primary outcome was ILD diagnosis and time in days between documented ILD and MDA5 antibody-positive DM diagnoses.

TAKEAWAY:

• Overall, 14 patients with DM (1.8%) were diagnosed with MDA5 antibody-positive DM in dermatology, rheumatology, or pulmonology departments (nine women and five men; age, 24-77 years; 79% were White and 7% were Black).
• ILD was diagnosed in 9 of the 14 patients (64%); 6 of the 14 (43%) met the criteria for RPILD. Two cases were diagnosed concurrently and two prior to MDA5 antibody-positive DM diagnosis.
• The median time between ILD and MDA5 antibody-positive DM diagnoses was 163 days.
• Gottron papules/sign and midfacial erythema were the most common dermatologic findings, and no association was seen between cutaneous signs and type of ILD.

IN PRACTICE:

“Establishing an accurate timeline between MDA5 antibody-positive DM and ILD can promote urgency among dermatologists to evaluate extracutaneous manifestations in their management of patients with DM for more accurate risk stratification and appropriate treatment,” the authors wrote.

Rheumatologists and their staff have been dutifully recording disease activity and patient-reported outcomes for decades, and now, all that drudgery is beginning to pay off with the introduction of artificial intelligence (AI) and natural language processing systems that can mine electronic health records (EHRs) for nuggets of research gold and accurately predict short-term rheumatoid arthritis (RA) outcomes.

“I think we have learned from our very early experiments that longitudinal deep learning models can forecast rheumatoid arthritis [RA] outcomes with actually surprising efficiency, with fewer patients than we assumed would be needed,” said Jinoos Yazdany, MD, MPH, chief of rheumatology at Zuckerberg San Francisco General Hospital and Trauma Center, and codirector of the University of California San Francisco (UCSF) Quality and Informatics Lab.

Yazdany_Jinoos_CA_3_web.jpg

At the 2024 Rheumatoid Arthritis Research Summit (RA Summit 2024), presented by the Arthritis Foundation and the Hospital for Special Surgery in New York City, Dr. Yazdany discussed why rheumatologists are well positioned to take advantage of predictive analytics and how natural language processing systems can be used to extract previously hard-to-find data from EHRs, which can then be applied to RA prognostics and research.
 

Data Galore

EHR data can be particularly useful for RA research because of the large volume of information, clinical data such as notes and imaging, less selection bias compared with other data sources such as cohorts or randomized controlled trials, real-time access, and the fact that many records contain longitudinal data (follow-ups, etc.).

However, EHR data may have gaps or inaccurate coding, and data such as text and images may require significant data processing and scrubbing before it can be used to advance research. In addition, EHR data are subject to patient privacy and security concerns, can be plagued by incompatibility across different systems, and may not represent patients who have less access to care, Dr. Yazdany said.

She noted that most rheumatologists record some measure of RA disease activity and patient physical function, and that patient-reported outcomes have been routinely incorporated into clinical records, especially since the 1980 introduction of the Health Assessment Questionnaire.

“In rheumatology, by achieving consensus and building a national quality measurement program, we have a cohesive national RA outcome measure selection strategy. RA outcomes are available for a majority of patients seen by rheumatologists, and that’s a critical strength of EHR data,” she said.
 

Spinning Text Into Analytics

The challenge for investigators who want to use this treasure trove of RA data is that more than 80% of the data are in the form of text, which raises questions about how to best extract outcomes data and drug dosing information from the written record.

As described in an article published online in Arthritis Care & Research February 14, 2023, Dr. Yazdany and colleagues at UCSF and Stanford University developed a natural language processing “pipeline” designed to extract RA outcomes from clinical notes on all patients included in the American College of Rheumatology’s Rheumatology Informatics System for Effectiveness (RISE) registry.

The model used expert-curated terms and a text processing tool to identify patterns and numerical scores linked to outcome measures in the records.

“This was an enormously difficult and ambitious project because we had many, many sites, the data was very messy, we had very complicated [independent review board] procedures, and we actually had to go through de-identification procedures because we were using this data for research, so we learned a lot,” Dr. Yazdany said.

The model processed 34 million notes on 854,628 patients across 158 practices and 24 different EHR systems.

In internal validation studies, the models had 95% sensitivity, 87% positive predictive value (PPV), and an F1 score (a measure of predictive performance) of 91%. Applying the model to an EHR from a large, non-RISE health system for external validation, the natural language processing pipeline had a 92% sensitivity, 69% PPV, and an F1 score of 79%.

The investigators also looked at the use of OpenAI large language models, including GPT 3.5 and 4 to interpret complex prescription orders and found that after training with 100 examples, GPT 4 was able to correctly interpret 95.6% of orders. But this experiment came at a high computational and financial cost, with one experiment running north of $3000, Dr. Yazdany cautioned.
 

Predicting Outcomes

Experiments to see whether an AI system can forecast RA disease activity at the next clinic visit are in their early stages.

Dr. Yazdany and colleagues used EHR data from UCSF and Zuckerberg San Francisco General Hospital on patients with two RA diagnostic codes at 30 days apart, who had at least one disease-modifying antirheumatic drug prescription and two Clinical Disease Activity Index (CDAI) scores 30 days apart.

One model, designed to predict CDAI at the next visit by “playing the odds” based on clinical experience, showed that about 60% of patients at UCSF achieved treat-to-target goals, while the remaining 40% did not.

This model performed barely better than pure chance, with an area under the receiver operating characteristic curve (AUC) of 0.54.

A second model that included the patient’s last CDAI score also fared little better than a roll of the dice, with an AUC of 0.55.

However, a neural network or “deep learning” model designed to process data akin to the way that the human brain works performed much better at predicting outcomes at the second visit, with an AUC of 0.91.

Applying the UCSF-trained neural network model to the Zuckerberg San Francisco General Hospital population, with different patient characteristics from those of UCSF, the AUC was 0.74. Although this result was not as good as that seen when applied to UCSF patients, it demonstrated that the model retains some predictive capability across different hospital systems, Dr. Yazdany said.

The next steps, she said, are to build more robust models based on vast and varied patient data pools that will allow the predictive models to be generalized across various healthcare settings.
 

The Here and Now

In the Q & A following the presentation, an audience member said that the study was “very cool stuff.”

“Is there a way to sort of get ahead and think of the technology that we’re starting to pilot? Hospitals are already using AI scribes, for example, to collect the data that is going to make it much easier to feed it to the predictive analytics that we’re going to use,” she said.

Dr. Yazdany replied that “over the last couple of years, one of the projects that we’ve worked on is to interview rheumatologists who are participating in the RISE registry about the ways that they are collecting [patient-reported outcomes], and it has been fascinating: A vast majority of people are still using paper forms.”

“The challenge is that our patient populations are very diverse. Technology, and especially filling out forms via online platforms, doesn’t work for everybody, and in some ways, filling out the paper forms when you go to the doctor’s office is a great equalizer. So, I think that we have some real challenges, and the solutions have to be embedded in the real world,” she added.

Dr. Yazdany’s research was supported by grants from the Agency for Healthcare Research & Quality and the National Institutes of Health. She disclosed consulting fees and/or research support from AstraZeneca, Aurinia, Bristol Myers Squibb, Gilead, and Pfizer.

She noted that most rheumatologists record some measure of RA disease activity and patient physical function, and that patient-reported outcomes have been routinely incorporated into clinical records, especially since the 1980 introduction of the Health Assessment Questionnaire.

“In rheumatology, by achieving consensus and building a national quality measurement program, we have a cohesive national RA outcome measure selection strategy. RA outcomes are available for a majority of patients seen by rheumatologists, and that’s a critical strength of EHR data,” she said.
 

Spinning Text Into Analytics

The challenge for investigators who want to use this treasure trove of RA data is that more than 80% of the data are in the form of text, which raises questions about how to best extract outcomes data and drug dosing information from the written record.

As described in an article published online in Arthritis Care & Research February 14, 2023, Dr. Yazdany and colleagues at UCSF and Stanford University developed a natural language processing “pipeline” designed to extract RA outcomes from clinical notes on all patients included in the American College of Rheumatology’s Rheumatology Informatics System for Effectiveness (RISE) registry.

The model used expert-curated terms and a text processing tool to identify patterns and numerical scores linked to outcome measures in the records.

“This was an enormously difficult and ambitious project because we had many, many sites, the data was very messy, we had very complicated [independent review board] procedures, and we actually had to go through de-identification procedures because we were using this data for research, so we learned a lot,” Dr. Yazdany said.

The model processed 34 million notes on 854,628 patients across 158 practices and 24 different EHR systems.

In internal validation studies, the models had 95% sensitivity, 87% positive predictive value (PPV), and an F1 score (a measure of predictive performance) of 91%. Applying the model to an EHR from a large, non-RISE health system for external validation, the natural language processing pipeline had a 92% sensitivity, 69% PPV, and an F1 score of 79%.

The investigators also looked at the use of OpenAI large language models, including GPT 3.5 and 4 to interpret complex prescription orders and found that after training with 100 examples, GPT 4 was able to correctly interpret 95.6% of orders. But this experiment came at a high computational and financial cost, with one experiment running north of $3000, Dr. Yazdany cautioned.
 

Predicting Outcomes

Experiments to see whether an AI system can forecast RA disease activity at the next clinic visit are in their early stages.

Dr. Yazdany and colleagues used EHR data from UCSF and Zuckerberg San Francisco General Hospital on patients with two RA diagnostic codes at 30 days apart, who had at least one disease-modifying antirheumatic drug prescription and two Clinical Disease Activity Index (CDAI) scores 30 days apart.

One model, designed to predict CDAI at the next visit by “playing the odds” based on clinical experience, showed that about 60% of patients at UCSF achieved treat-to-target goals, while the remaining 40% did not.

This model performed barely better than pure chance, with an area under the receiver operating characteristic curve (AUC) of 0.54.

A second model that included the patient’s last CDAI score also fared little better than a roll of the dice, with an AUC of 0.55.

However, a neural network or “deep learning” model designed to process data akin to the way that the human brain works performed much better at predicting outcomes at the second visit, with an AUC of 0.91.

Applying the UCSF-trained neural network model to the Zuckerberg San Francisco General Hospital population, with different patient characteristics from those of UCSF, the AUC was 0.74. Although this result was not as good as that seen when applied to UCSF patients, it demonstrated that the model retains some predictive capability across different hospital systems, Dr. Yazdany said.

The next steps, she said, are to build more robust models based on vast and varied patient data pools that will allow the predictive models to be generalized across various healthcare settings.
 

The Here and Now

In the Q & A following the presentation, an audience member said that the study was “very cool stuff.”

“Is there a way to sort of get ahead and think of the technology that we’re starting to pilot? Hospitals are already using AI scribes, for example, to collect the data that is going to make it much easier to feed it to the predictive analytics that we’re going to use,” she said.

Dr. Yazdany replied that “over the last couple of years, one of the projects that we’ve worked on is to interview rheumatologists who are participating in the RISE registry about the ways that they are collecting [patient-reported outcomes], and it has been fascinating: A vast majority of people are still using paper forms.”

“The challenge is that our patient populations are very diverse. Technology, and especially filling out forms via online platforms, doesn’t work for everybody, and in some ways, filling out the paper forms when you go to the doctor’s office is a great equalizer. So, I think that we have some real challenges, and the solutions have to be embedded in the real world,” she added.

Dr. Yazdany’s research was supported by grants from the Agency for Healthcare Research & Quality and the National Institutes of Health. She disclosed consulting fees and/or research support from AstraZeneca, Aurinia, Bristol Myers Squibb, Gilead, and Pfizer.

Even in large urban areas there aren’t enough rheumatologists to go around, and as a 2015 American College of Rheumatology workforce study projected, the number of rheumatology providers is expected to drop by 25% by the year 2030, while the demand for patient care in rheumatology is expected to increase by more than 100%.

The shortage of rheumatology care is even more acute in rural areas, but as a pilot project supported by the Arthritis Foundation shows, linking rheumatologists to health centers in remote and underserved locations via telehealth can help community providers improve care for patients with rheumatic diseases.

The novel collaborative model was described by Alfredo Rivadeneira, MD, professor of medicine in the division of rheumatology, allergy, and immunology at the University of North Carolina (UNC) School of Medicine in Chapel Hill, North Carolina.

“We found that this pilot, a unique partnership in North Carolina, improves access to rheumatology care to a rural population with high satisfaction scores. It underlines the importance of seeking collaboration with community providers when implementing these programs. It also allows timely specialty care and alleviates the barriers relating to transportation, insurance coverage, and telecommunication challenges,” he said at the 2024 Rheumatoid Arthritis Research Summit presented by the Arthritis Foundation and the Hospital for Special Surgery in New York City. 
 

Too Many Patients, Too Few Rheumatologists

Access to health is challenging for people from traditionally underserved racial and ethnic backgrounds, especially in states such as North Carolina, where 40% of the population lives in rural counties, which have higher age-adjusted mortality than more densely populated areas of the state, Dr. Rivadeneira said. 

In addition, 42% of the North Carolina residents seen at the state’s 42 Federally Qualified Health Centers (FQHCs) don’t have health insurance, which is higher than the average of 23% uninsured seen at FQHCs in other states.

There are currently approximately 250 rheumatology providers in North Carolina, the majority of whom work in the states’ three academic medical centers. Currently, North Carolina has an estimated population of 10 million people, which is projected to increase to 11.7 million by 2030. And by 2030, 20% of North Carolinians will be aged ≥ 65 years, Dr. Rivadeneira said, highlighting the need for expanded rheumatology care. 

Although telehealth services could be an option for expanding services to underserved communities, only 14 of the 42 FQHCs in the state use telehealth and only on a limited basis because it is not sufficiently reimbursed. 

Rivadeneira pointed to a 2022 study that showed how patients with rheumatic and musculoskeletal disease patients in North Carolina were less likely to use online patient portals if they lived in rural areas; came from racial or ethnic minority backgrounds; were older, men, had lower economic status (Medicaid enrollment or uninsured); or spoke a language other than English as their primary tongue. 
 

Pilot Project

To help smooth out some of the above-mentioned disparities, Dr. Rivadeneira and colleagues, in collaboration with the Arthritis Foundation, started a pilot project in 2022 designed to enhance access to rheumatology specialty care for rural residents through a shared telehealth model between the UNC rheumatology clinic and two separate Piedmont Health Services clinics in rural areas.

The project includes tailored educational sessions designed to empower Piedmont Health Services providers for evaluating and managing patients with rheumatic diseases.

Patients with prior diagnoses of rheumatologic diseases who were lost to rheumatology specialty care follow-up and those with new rheumatic symptoms who had transportation and/or financial barriers to receiving specialty care are triaged to the shared telemedicine visits.

Providers conduct monthly clinic sessions via shared visits between the on-site Piedmont Health Services provider and patients, with off-site UNC rheumatology fellows and attending physicians connected virtually. 

The educational component of the project includes monthly didactic sessions offered to all Piedmont Health Services providers across 12 locations. 

The topics that were chosen cover the most common rheumatologic conditions seen by community providers, including evaluating pain from a rheumatology perspective; using antinuclear antibodies and other serologies; evaluating and managing rheumatoid arthritis, lupus, gout, giant cell arteritis, polymyalgia rheumatica, and osteoarthritis; and methotrexate management and complications. 

“One of the aspects of this pilot that I want to emphasize is the importance of having the generalists with the patient, relaying the objective data, especially the physical exam, and that’s one of the great features of this model. It also provides a stable platform for telehealth to the individual patients, as many of these patients don’t have access to health technology,” Dr. Rivadeneira said. 
 

Thumbs Up

Both patients and general practitioners in the Piedmont Health system expressed high degrees of satisfaction with the shared telehealth program. Patients especially liked the time they saved not having to travel to see a specialist, and a large majority agreed that the visits were “as good as” in-person visits, felt that their concerns were addressed appropriately during the virtual visit, expressed overall satisfaction, and said they would like to continue virtual visits.

Physicians expressed a high degree of satisfaction with the rheumatology didactic sessions and said that the sessions enhanced their knowledge of evaluating and managing or co-managing rheumatologic diseases, as well as helping them to feel comfortable about applying this knowledge to patient care.

Dr. Rivadeneira noted that the pilot study was limited by low levels of Piedmont Health Services physician participation (two out of 45 total participated in shared visits), and only three or four providers typically took part in each didactic session. 
 

How to Improve?

In a follow-up study, the investigators asked Piedmont Health Services providers about barriers to rheumatology care, the most common and challenging diseases they encountered, how to improve the didactic components, and their perspectives on the pilot and how it may have affected referral patterns to rheumatology care.

The providers identified the cost of diagnostic evaluations and medications, transportation, long wait times, and language as the main barriers to patient access of rheumatology care.

“Additionally, over a third of them encountered patients on a weekly basis that were overdue for a visit with a rheumatologist,” Dr. Rivadeneira said. 

“Direct participation in the physical exam by the primary care provider enhances greatly, in my opinion, these telehealth visits. Focused didactic sessions, electronic handouts and/or quick access guides could empower more rural community providers to manage rheumatic diseases,” he concluded.

In the Q&A following the presentation, Laura Cappelli, MD, MHS, MS, associate professor of medicine in the division of rheumatology at Johns Hopkins School of Medicine in Baltimore, asked Dr. Rivadeneira how rheumatologists involved felt about the program and whether his team did any surveying or qualitative work with them.

“Just so you know, the rheumatologist was me,” he replied.

“I’m very picky about telemedicine,” he continued. “I don’t like it, I prefer, as most of us do, to have the patient there. But having the provider there, doing the exam, and you guiding them — I can ask, ‘Did you check their joints? Did you check their strength?’ — makes a huge difference and makes me feel comfortable with the sessions.”

Dr. Rivadeneira added that if a particular case was too complex or too vague to adequately assess via telehealth, he would arrange to see the patient in person.

The project was supported by the Arthritis Foundation. Dr. Rivadeneira and Dr. Cappelli reported no conflicts of interest.

The US Food and Drug Administration (FDA) has approved the biosimilar ustekinumab-aekn (Selarsdi) for the treatment of moderate to severe plaque psoriasis and psoriatic arthritis in adults and pediatric patients aged 6 years or older.

This is the second ustekinumab biosimilar approved by the regulatory agency and is the second biosimilar approval in the United States for the Icelandic pharmaceutical company Alvotech in partnership with Teva Pharmaceuticals. 

Ustekinumab (Stelara) is a human monoclonal antibody targeting interleukin (IL)–12 and IL-23. The drug, manufactured by Johnson & Johnson, totaled nearly $7 billion in sales in 2023 alone, according a press release. 

“Bringing Selarsdi to market in the US early next year presents a significant opportunity to improve patient access to a vital biologic in inflammatory disease and contribute to the reduction of inflationary pressure in healthcare costs,” the chairman and CEO of Alvotech said in the release. 

The first ustekinumab biosimilar, ustekinumab-auub (Wezlana), was approved by the FDA in on October 31, 2023 and is interchangeable with the reference product. This allows pharmacists to substitute the biosimilar for the reference product without involving the prescribing clinician (according to state law). Besides psoriasis and psoriatic arthritis, ustekinumab-auub was also approved for treating moderate to severely active Crohn’s disease and ulcerative colitis. Ustekinumab-aekn does not have an interchangeability designation and was not approved for Crohn’s disease or ulcerative colitis. 

The approval of ustekinumab-aekn was based on two clinical studies. A randomized, double blind, multicenter, 52-week study of 581 patients with moderate to severe plaque psoriasis demonstrated that the biosimilar was as effective as the reference product, with equivalent safety and immunogenicity profiles. A phase 1, randomized, double-blind, single-dose, parallel-group, three-arm study also compared the pharmacokinetic profile of the biosimilar to ustekinumab in 294 healthy adults.

Ustekinumab-aekn is expected to be marketed in the United States on or after February 21, 2025 per a settlement and license agreement with Johnson & Johnson.

If your gut is telling you that your disease-modifying antirheumatic drugs (DMARDs) aren’t working as well as they should, listen to it.

That’s the advice of Rebecca B. Blank, MD, PhD, a rheumatologist at NYU Langone Health in New York City, who studies methods for modulating the gut microbiome to enhance DMARD efficacy for patients with rheumatoid arthritis (RA).

“The baseline gut microbiome can predict patient responsiveness to methotrexate,” said Dr. Blank at the 2024 Rheumatoid Arthritis Research Summit, presented by the Arthritis Foundation and the Hospital for Special Surgery in New York City.

Dr. Blank and colleagues are investigating how the intestinal microbiome may influence drug metabolism and the therapeutic potential of short-chain fatty acids for improving the efficacy of methotrexate in patients with RA.
 

Mucosal Barrier Disruption

There are myriad factors contributing to the development and progression of RA, including dysbiosis, or disruption, of the mucosal barrier, Dr. Blank explained.

“Dysbiosis can be detected in at-risk individuals before clinical signs of rheumatoid arthritis even occur,” she said.

Dr. Blank cited a 2021 study of the gut-joint axis in RA,which indicated that subclinical inflammation in the oral, gut, and/or lung mucosa may lead to inflammatory arthritis.

“When there’s a break in the mucosal barrier, either bacteria or their bacterial products can translocate into the lamina propria and then lead to an inflammatory T-cell response, and in addition, bacteria or their products can induce auto-antibody formation, which can then lead to joint inflammation,” she said.

Dr. Blank and colleagues, as well as other research groups, showed that gut bacterial colonization by Prevotella copri can induce an inflammatory response in gut lamina propria, and that people with RA have increased abundance of P copri relative to people without RA.
 

DMARD Resistance

To see whether microbial dysbiosis might play a role in DMARD-resistant RA, Dr. Blank and her team looked at patients with new-onset RA who were scheduled for treatment with methotrexate as their first-line medication. They classified responders as those patients with a change in Disease Activity Score in 28 joints (DAS28) of at least 1.8 points.

They then conducted 16S rRNA sequencing and shotgun sequencing on patient fecal samples taken at baseline to determine whether baseline microbiome differences might contribute to responses to methotrexate.

“And so indeed, we were able to find a human gut microbial signature that predicted methotrexate responsiveness in these baseline microbiome samples,” Dr. Blank said.

They identified 462 differences in gene orthologs (ie, genes preserved during evolution and speciation) that differed between responders and nonresponders, narrowed the list down to the top 38, and then developed a predictive model for response to methotrexate with an area under the receiver operating characteristic curve of 0.84.

The investigators then cultured fecal baseline samples with methotrexate to see how levels of the drug would be affected over time and found that samples from nonresponders metabolized methotrexate at a faster rate than samples from patients who had clinical responses to the drug.

Their work was further supported by colleagues at the University of California San Francisco, who found evidence in mouse models to suggest that microbial metabolism plays a role in methotrexate levels in plasma.
 

Modulating the Gut

“Our next question was: Can we modulate the gut microbiome to improve methotrexate efficacy?” Dr. Blank said.

They considered probiotics and prebiotics as possible means for modulating gut microbiota, but evidence of efficacy for these agents has been decidedly mixed, she noted.

Instead, the investigators focused on short-chain fatty acids, gut microbial fermentation byproducts of indigestible carbohydrates, which have been demonstrated to help improve gut mucosal barrier integrity and promote a more tolerant immune response.

One such short-chain fatty acid, butyrate, is produced through microbial fermentation of dietary fiber in the colon; it is available in various foods and in supplement form.

Butyrate has been shown to ameliorate inflammatory arthritis in a collagen-induced arthritis model, and in this model, methotrexate efficacy was increased with the addition of butyrate or butyrate-producing bacterial species.

Dr. Blank and colleagues compared patients with new-onset RA treated with methotrexate alone or methotrexate plus butyrate for 4 months and looked at up to 2 months of methotrexate plus butyrate treatment in patients who had suboptimal response to methotrexate alone.

In preliminary analyses, they found that at baseline, fecal butyrate was significantly elevated in methotrexate responders compared with in nonresponders. In addition, in the new-onset RA cohort, they saw that the 4-month responsiveness rate was 52.6% for those treated with methotrexate compared with 64.7% for those treated with methotrexate plus butyrate.

“Although this difference was not statistically significant, it’s exciting to think we may have an impact. What’s more, we were really excited to find that oral butyrate can lead to increased microbial diversity,” she said.
 

What Are You Measuring?

In the Q & A following the presentation, Clifton O. Bingham III, MD, director of the Johns Hopkins Arthritis Center in Baltimore, Maryland, commented that “the definitions of response and nonresponse are quite variable, depending on the studies that you use, and I think this is potentially a real problem for this entire line of investigation.”

He noted that the DAS28, as used by Dr. Blank and colleagues, was developed in 1993, and that American College of Rheumatology response criteria, employed by other investigators who also presented during the session, were developed in 1990.

“It was a very different world when those criteria and those response indices were developed for patients with a very different disease from what we know as RA today,” he said.

He added that “I see a tremendous need for the rheumatology community to reevaluate what we define as responders and nonresponders, so that in all of these studies that are being done around the world, there is one definition that we understand [for] someone who is doing better, responding, or not responding.”

Dr. Blank’s work is supported by NYU, the Arthritis Foundation, and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. She reported having no conflicts of interest to disclose. Dr. Bingham had no relevant conflicts of interest to disclose.
