Questionnaire for patients with psoriasis might identify risk of axial involvement
Preliminary findings are encouraging
NEW YORK – A questionnaire-based screening tool appears to accelerate the time to diagnosis of axial involvement in patients presenting with psoriasis but no clinical signs of joint pain, according to a study called ATTRACT that was presented at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.
The risk of a delayed diagnosis of an axial component in patients with psoriasis, meaning a delay in the underlying diagnosis of psoriatic arthritis (PsA), is substantial, according to Devis Benfaremo, MD, of the department of clinical and molecular science at Marche Polytechnic University, Ancona, Italy.
There is “no consensus for the best strategy to achieve early detection of joint disease” in patients presenting with psoriasis, but Dr. Benfaremo pointed out that missing axial involvement is a particular problem because it is far more likely than swollen joints to be missed on clinical examination.
While about one in three patients with psoriasis have or will develop psoriatic arthritis, according to the National Psoriasis Foundation, delays in diagnosis are common, according to Dr. Benfaremo. In patients with undiagnosed PsA characterized by axial involvement alone, subtle symptoms can be overlooked or attributed to other causes.
There are several screening questionnaires to detect joint symptoms in patients presenting with psoriasis, such as the five-question Psoriasis Epidemiology Screening Tool, but the questionnaire tested in the ATTRACT trial is focused on detecting axial involvement specifically. It was characterized as the first to do so.
In the ongoing ATTRACT study, 253 patients with psoriasis but no history of PsA or axial disease have been enrolled so far. In the study, patients are screened for PsA based on a patient-completed yes-or-no questionnaire, which takes only a few minutes to complete.
“It is a validated questionnaire for axial [spondyloarthritis], but we have adopted it for detection of psoriasis patients with PsA,” Dr. Benfaremo explained.
The questionnaire for axial spondyloarthritis (axSpA) was initially evaluated and validated by Fabian Proft, MD, head of the clinical trials unit at Charité Hospital, Berlin. In addition to a patient self-completed questionnaire, Dr. Proft and coinvestigators have also created a related questionnaire to be administered by physicians.
In the ATTRACT study, patients completed the questionnaire on an electronic device in the waiting room. Positive answers to specific questions about symptoms, which addressed back pain and joint function as well as joint symptoms, divided patients into three groups:
- Group A patients did not respond positively to any of the symptom questions that would prompt suspicion of axial disease. These represented about one-third of those screened so far.
- Group B patients were those who answered positively to at least two questions that related to a high suspicion of axial involvement. These represented 45% of patients.
- The remaining patients were placed in Group C, a category of intermediate risk based on positive responses to some, but not all, questions relating to axial symptoms.
Those in group B are being referred to rheumatology. Patients in group C are given “conditional” eligibility based on the presence of additional risk factors.
AxSpA screening tool ‘makes sense’ for potential use in PsA
The primary outcome of the ATTRACT trial is early identification of axial PsA. Correctly identifying patients with or without peripheral joint involvement is one of several secondary outcomes. The identification of patients who fulfill Assessment Spondyloarthritis International Society (ASAS) criteria for axSpA is another secondary outcome.
Of the 114 patients placed in group B and analyzed so far, 87 have completed an assessment by a rheumatologist with laboratory analyses and imaging, as well as a clinical examination.
Of those 87 assessed by a rheumatologist, 17 did not have either axial or peripheral inflammation. Another 19 were diagnosed with axial disease, including 14 who met ASAS criteria. A total of 10 were classified as having PsA with peripheral inflammation, according to Classification for Psoriatic Arthritis criteria, and 41 are still being considered for a diagnosis of axial or peripheral PsA on the basis of further workup.
“Among the patients with axial PsA, only 10% had elevated C-reactive protein levels,” according to Dr. Benfaremo, echoing previous evidence that inflammatory biomarkers by themselves have limited value for identifying psoriasis patients at high risk of joint involvement.
The findings are preliminary, but Dr. Benfaremo reported that the questionnaire is showing promise for the routine stratification of patients who should be considered for a rheumatology consultation.
If further analyses validate the clinical utility of these stratifications, there is the potential for a substantial acceleration to the diagnosis of PsA.
When contacted to comment about this work, Dr. Proft said that there is an important need for new strategies reduce delay in the diagnosis of PsA among patients presenting with psoriasis. He thinks the screening tool he developed for axSpA “makes sense” as a potential tool in PsA.
“If validated, this could be a very useful for earlier identification of PsA,” Dr. Proft said. He reiterated the importance of focusing on axial involvement.
“Previous screening tools have focused on symptoms of PsA more generally, but inflammation in the peripheral joints is something that you can easily see in most patients,” he said.
In addition to the patient-completed questionnaire and the physician-administered questionnaire, Dr. Proft has also evaluated an online self-referral tool for patients.
“If we can diagnose PsA earlier in the course of disease, we can start treatment earlier, prevent or delay joint damage, and potentially improve outcomes for patients,” Dr. Proft said. He considers this an important direction of research.
Dr. Benfaremo and Dr. Proft reported no potential conflicts of interest.

NAFLD strongly correlated with psoriasis, PsA; risk linked to severity
NEW YORK – – and probably in those with psoriatic arthritis (PsA) as well, according to a systematic review and meta-analysis presented at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.
“Our findings imply that psoriatic patients should be screened with an ultrasonographic exam in cases where there are metabolic features that are associated with NAFLD,” reported Francesco Bellinato, MD, a researcher in the section of dermatology and venereology, University of Verona (Italy).
The data are strong. Of 76 nonduplicate publications found in the literature, the 11 observational studies included in the meta-analysis met stringent criteria, including a diagnosis of psoriasis and PsA based on objective criteria, NAFLD confirmed with liver biopsy or imaging, and odds rates calculated with 95% confidence intervals.
From these 11 studies, aggregate data were available for 249,333 psoriatic patients, of which 49% had NAFLD, and 1,491,402 were healthy controls. Among the controls, 36% had NAFLD. Four of the studies were from North America, four from Europe, and three from Asia.
In the pooled data, the risk of NAFLD among those with psoriasis relative to healthy controls fell just short of a twofold increase (odds ratio, 1.96; 95% CI, 1.70-2.26; P < .001). When stratified by studies that confirmed NAFLD by biopsy relative to ultrasonography, there was no significant heterogeneity.
Eight of the studies included an analysis of relative risk in the context of skin lesion severity defined by Psoriasis Area and Severity Index (PASI) score. Relative to those without NAFLD, psoriatic patients with NAFLD had a significant greater mean PASI score on a pooled weighted mean difference analysis (OR, 3.93; 95% CI, 2.01-5.84; P < .0001).
For PsA relative to no PsA in the five studies that compared risk between these two groups, the risk of NAFLD was again nearly twofold higher. This fell short of conventional definition of statistical significance, but it was associated with a strong trend (OR, 1.83; 95% CI, 0.98-3.43; P = .06).
The risk of NAFLD among patients with psoriasis was not found to vary significantly when assessed by univariable meta-regressions across numerous characteristics, such as sex and body mass index.
In one of the largest of the observational studies included in the meta-analysis by Alexis Ogdie, MD, associate professor of medicine and epidemiology at the University of Pennsylvania, Philadelphia, and colleagues, data were analyzed in more than 1.5 million patients, which included 54,251 patients with rheumatoid arthritis. While the hazard ratio of NAFLD was increased for both psoriasis (HR, 2.23) and PsA (HR, 2.11), it was not elevated in those with RA (HR, 0.96).
Risk by severity, possible mechanisms
This study also included an analysis of NAFLD risk according to psoriasis severity. While risk was still significant among those with mild disease (HR, 1.18; 95% CI, 1.07-1.30), it was almost twofold greater in those with moderate to severe psoriasis (HR, 2.23; 95% CI, 1.73-2.87).
Dr. Bellinato conceded that the mechanisms underlying the association between psoriasis and NAFLD are unknown, but he said “metaflammation” is suspected.
“The secretion of proinflammatory, prothrombotic, and oxidative stress mediators in both psoriatic skin and adipose tissue might act systemically and promote insulin resistance and other metabolic derangements that promote the development and progression of NAFLD,” Dr. Bellinato explained.
He thinks that noninvasive screening methods, such as currently used methods to calculate fibrosis score, might be useful for evaluating patients with psoriasis for NAFLD and referring them to a hepatologist when appropriate.
Given the strong association with NAFLD, Dr. Bellinato suggested that “the findings of this meta-analysis pave the way for novel, large, prospective, and histologically based studies.”
The association between psoriasis and NAFLD is clinically relevant, agreed Joel M. Gelfand, MD, vice-chair of clinical research and medical director of the clinical studies unit, department of dermatology, University of Pennsylvania, Philadelphia.
“It is not clear if psoriasis causes fatty liver disease or vice versa, but clinicians should be aware of this association,” he said in an interview. Dr. Gelfand was a coauthor of the study by Dr. Ogdie and colleagues and led another more recent population-based study that implicated methotrexate as a factor in psoriasis-related hepatotoxicity.
If NAFLD is identified in a patient with psoriasis, treatments are limited, but Dr. Gelfand suggested that patients should be made aware of the risk. “Clinicians should encourage patients with psoriasis to take measures to protect their liver, such as avoiding drinking alcohol to excess and trying to maintain a healthy body weight,” he said.
Dr. Bellinato reported no conflicts of interest. Dr. Gelfand has financial relationships with more than 10 pharmaceutical companies, including those that make therapies for psoriasis.

Methotrexate’s impact on COVID-19 vaccination: New insights made
Patients who take methotrexate for a variety of immune-mediated inflammatory diseases and pause taking the drug following receipt of a COVID-19 vaccine dose did not have a higher risk of disease flare and had higher antireceptor binding domain (anti-RBD) antibody titers and increased immunogenicity when compared with continuing the drug, three recent studies suggest.
In one study, British researchers examined the effects of a 2-week break in methotrexate therapy on anti-RBD titers following receipt of a third COVID-19 vaccine dose. In their paper published in The Lancet: Respiratory Medicine, they reported results from a randomized, open-label, superiority trial that suggested pausing the drug improved immunogenicity, compared with no break.
In two trials presented at the European Alliance of Associations for Rheumatology (EULAR) 2022 Congress, a team from India set out to determine whether holding methotrexate after receiving both doses of a COVID-19 vaccine, or holding it only after the second dose, was safe and effective. They found that pausing methotrexate only following the second dose contributed to a lower flare risk, and that patients had higher anti-RBD titers when holding methotrexate for 2 weeks following each dose.
Pausing methotrexate after booster
The 2-week methotrexate break and booster vaccine dose data in the Vaccine Response On Off Methotrexate (VROOM) trial showed that after a month, the geometric mean antispike 1 (S1)-RBD antibody titer was 10,798 U/mL (95% confidence interval [CI], 8,970-12,997) in the group that continued methotrexate and 22,750 U/mL (95% CI, 19,314-26,796) in the group that suspended methotrexate; the geometric mean ratio was 2.19 (P < .0001; mixed-effects model), reported Abhishek Abhishek, MD, PhD, professor of rheumatology at the University of Nottingham in Nottingham, England, and colleagues.
Prior research showed that stopping methotrexate therapy for 2 weeks following the seasonal influenza vaccine contributed to better vaccine immunity among patients with rheumatoid arthritis, but there was no impact of stopping the drug for up to 4 weeks before vaccination on vaccine-related immunity, the researchers noted.
It is crucial in maximizing long-lasting vaccine protection in people who are possibly susceptible through immune suppression at this point in the COVID-19 vaccination regimen, the study team noted.
“Evidence from this study will be useful for policymakers, national immunization advisory committees, and specialist societies formulating recommendations on the use of methotrexate around the time of COVID-19 vaccination. This evidence will help patients and clinicians make informed choices about the risks and benefits of interrupting methotrexate treatment around the time of COVID-19 vaccination, with implications for the potential to extend such approaches to other therapeutics,” they wrote.
In American College of Rheumatology (ACR) guidance for COVID-19 vaccination, the organization advised against using standard synthetic disease-modifying antirheumatic medicines such as methotrexate “for 1-2 weeks (as disease activity allows) after each COVID-19 vaccine dose,” given the at-risk population and public health concerns, Jeffrey A. Sparks, MD, MMSc, assistant professor of medicine and associate physician at Brigham and Women’s Hospital and Harvard Medical School, Boston, and Sara K. Tedeschi, MD, MPH, assistant professor of medicine at Harvard Medical School, noted in an accompanying editorial in The Lancet: Respiratory Medicine.
However, when the ACR developed this statement, there was only one trial involving patients with rheumatoid arthritis who paused methotrexate following seasonal influenza vaccination, the editorialists said.
“Although this finding adds to the evidence base to support interruption of methotrexate after vaccination, a shared decision process is needed to weigh the possible benefit of optimizing protection from COVID-19 and the possible risk of underlying disease flare,” they added.
Dr. Abhishek and colleagues assessed 254 patients with immune-mediated inflammatory disease from dermatology and rheumatology clinics across 26 hospitals in the United Kingdom. Participants had been diagnosed with systemic lupus erythematosus, rheumatoid arthritis, atopic dermatitis, polymyalgia rheumatica, axial spondyloarthritis, and psoriasis without or with arthritis. They had also been taking up to 25 mg of methotrexate per week for 3 months or longer and had received two doses of either the Pfizer/BioNTech BNT162b2 vaccine or AstraZeneca/Oxford viral vector vaccine. The booster dose was most often the Pfizer BNT162b2 vaccine (82%). The patients’ mean age was 59 years, with females comprising 61% of the cohort. Participants were randomly assigned 1:1 to either group.
Investigators performing laboratory analysis were masked to cohort assignment, and clinical research staff, data analysts, participants, and researchers were unmasked.
The elevated antibody response of patients who suspended methotrexate was the same across different kinds of immune-mediated inflammatory disease, primary vaccination platform, SARS-CoV-2 infection history, and age.
Notably, no intervention-associated adverse events were reported, the study team noted.
The conclusions that could be drawn from the booster-dose study were limited by the trial’s modest cohort size, the small number of patients in exploratory subgroup analyses, a lack of information about differences in prescription drug behavior, and early termination’s effect on the researchers’ ability to identify differences between subgroups and in secondary outcomes, the authors noted.
Other limitations included a lack of generalizability to patients with active disease who couldn’t stop therapy and were not included in the investigation, and participants were not blinded to what group they were in, the researchers said.
Expert commentary
This current study is consistent with other studies over the last several months showing that methotrexate harms both humoral and cell-mediated COVID-19 responses, noted Kevin Winthrop, MD, MPH, professor of infectious disease and public health at Oregon Health & Science University, Portland, who was not involved in the study. “And so now the new wave of studies are like this one, where they are holding methotrexate experimentally and seeing if it makes a difference,” he said.
“The one shortcoming of this study – and so far, the studies to date – is that no one has looked at whether the experimental hold has resulted in a change in T-cell responses, which ... we are [now] recognizing [the importance of] more and more in long-term protection, particularly in severe disease. Theoretically, holding [methotrexate] might help enhance T-cell responses, but that hasn’t been shown experimentally.”
Dr. Winthrop pointed out that one might get the same benefit from holding methotrexate for 1 week instead of 2 and that there likely is a reduced risk of flare-up from underlying autoimmune disease.
It is still not certain that this benefit extends to other vaccines, Dr. Winthrop noted. “It is probably true for most vaccines that if you hold methotrexate for 1 or 2 weeks, you might see some short-term benefit in responsiveness, but you don’t know that there is any clinical meaningfulness of this. That’s going to take other long-term studies. You don’t know how long this benefit lasts.”
Pausing methotrexate during initial COVID vaccine doses
Patients with either rheumatoid arthritis or psoriatic arthritis had higher anti-RBD antibody titers when methotrexate was stopped after both doses of the AstraZeneca vaccine, or simply after the second dose, than when methotrexate was continued, according to results from two single-center, randomized controlled trials called MIVAC I and II, Anu Sreekanth, MD, of Sree Sudheendra Medical Mission in Kochi, Kerala, India, and colleagues reported at EULAR 2022.
Results from MIVAC I indicated that there was a higher flare rate when methotrexate was stopped after both vaccine doses, but there was no difference in flare rate in MIVAC II when methotrexate was stopped only after the second dose as opposed to stopping it after both doses.
In the MIVAC I trial, 158 unvaccinated patients were randomized 1:1 to a cohort in which methotrexate was held for 2 weeks after both doses and a cohort in which methotrexate was continued despite the vaccine. In MIVAC II, 157 patients continued methotrexate while receiving the first vaccine dose. These patients were subsequently randomized either to continue or to stop methotrexate for 2 weeks following the second dose.
The findings from MIVAC I demonstrated the flare rate was lower in the methotrexate-continue group than in the methotrexate-pause group (8% vs. 25%; P = .005) and that the median anti-RBD titer was significantly higher for the methotrexate-pause group than the methotrexate-continue group (2,484 vs. 1,147; P = .001).
The results from MIVAC II trial indicated that there was no difference in flare rates between the two study groups (7.9% vs. 11.8%; P = .15). Yet, the median anti-RBD titer was significantly higher in the methotrexate-pause cohort than in the methotrexate-continue cohort (2,553 vs. 990; P = .001).
The report suggests there is a flare risk when methotrexate is stopped, Dr. Sreekanth noted. “It appears more logical to hold only after the second dose, as comparable anti-RBD titers are generated” with either approach, Dr. Sreekanth said.
Expert commentary: MIVAC I and II
Inés Colmegna, MD, associate professor at McGill University in Montreal, noted that it was intriguing that the risk of flares in MIVAC II is half of that reported after each of the doses of MIVAC I. “It is also worth emphasizing that despite the reported frequency of flares, the actual disease activity [as measured by the Disease Activity Score in 28 joints] in patients who did or did not withhold methotrexate was similar.
“MIVAC I and II have practical implications as they help to adequately inform patients about the risk and benefit trade of withholding methotrexate post–COVID-19 vaccination,” Dr. Colmegna told this news organization.
“Additional information would help to [further] interpret the findings of these studies, including whether any of the participants were taking any other DMARDs; data on the severity of the flares and functional impact; analysis of factors that predict the risk of flares, such as higher doses of methotrexate; [and change in] disease activity scores pre- and postvaccination,” Dr. Colmegna concluded.

Dr. Abhishek is cochair of the ACR/EULAR CPPD Classification Criteria Working Group and the OMERACT CPPD Working Group.

Patients who take methotrexate for a variety of immune-mediated inflammatory diseases and pause taking the drug following receipt of a COVID-19 vaccine dose did not have a higher risk of disease flare and had higher antireceptor binding domain (anti-RBD) antibody titers and increased immunogenicity when compared with continuing the drug, three recent studies suggest.
In one study, British researchers examined the effects of a 2-week break in methotrexate therapy on anti-RBD titers following receipt of a third COVID-19 vaccine dose. In their paper published in The Lancet: Respiratory Medicine, they reported results from a randomized, open-label, superiority trial that suggested pausing the drug improved immunogenicity, compared with no break.
In two trials presented at the European Alliance of Associations for Rheumatology (EULAR) 2022 Congress, a team from India set out to determine whether holding methotrexate after receiving both doses of a COVID-19 vaccine, or holding it only after the second dose, was safe and effective. They found that pausing methotrexate only following the second dose contributed to a lower flare risk, and that patients had higher anti-RBD titers when holding methotrexate for 2 weeks following each dose.
Pausing methotrexate after booster
The 2-week methotrexate break and booster vaccine dose data in the Vaccine Response On Off Methotrexate (VROOM) trial showed that after a month, the geometric mean antispike 1 (S1)-RBD antibody titer was 10,798 U/mL (95% confidence interval [CI], 8,970-12,997) in the group that continued methotrexate and 22,750 U/mL (95% CI, 19,314-26,796) in the group that suspended methotrexate; the geometric mean ratio was 2.19 (P < .0001; mixed-effects model), reported Abhishek Abhishek, MD, PhD, professor of rheumatology at the University of Nottingham in Nottingham, England, and colleagues.
Prior research showed that stopping methotrexate therapy for 2 weeks following the seasonal influenza vaccine contributed to better vaccine immunity among patients with rheumatoid arthritis, but there was no impact of stopping the drug for up to 4 weeks before vaccination on vaccine-related immunity, the researchers noted.
It is crucial in maximizing long-lasting vaccine protection in people who are possibly susceptible through immune suppression at this point in the COVID-19 vaccination regimen, the study team noted.
“Evidence from this study will be useful for policymakers, national immunization advisory committees, and specialist societies formulating recommendations on the use of methotrexate around the time of COVID-19 vaccination. This evidence will help patients and clinicians make informed choices about the risks and benefits of interrupting methotrexate treatment around the time of COVID-19 vaccination, with implications for the potential to extend such approaches to other therapeutics,” they wrote.

Neural networks can distinguish PsA from rheumatoid arthritis on MRI
Hand images are sufficient
NEW YORK – On the basis of MRI images of the hand, a neural network has been trained to distinguish seronegative and seropositive rheumatoid arthritis (RA) from psoriatic arthritis (PsA) as well as from each other, according to a study that was presented at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.
In the work so far, the neural network was correct about 70% of the time in the absence of any further clinical analyses, according to David Simon, MD, a rheumatologist in the department of internal medicine at Friedrich-Alexander University, Erlangen, Germany.
Previous to this work, “there has been no study that has exclusively used hand MRI data and deep learning without requiring further expert input for the classification of arthritides,” Dr. Simon said.
In fact, when demographic and clinical data were added, there was no improvement in the performance of patient classification relative to the deep learning classification alone, according to the data presented by Dr. Simon.
The images were evaluated with residual neural networks (ResNet), which represents a sophisticated form of deep learning to facilitate the flow of information across the network layers as they form to improve accuracy in their ability to distinguish one form of disease from the other. The training was performed on images from the T1 coronal, T2 corona1, T1 coronal fat suppressed with contrast, T1 axial fat suppressed with contrast, and T2 fat suppressed axial sequences.
The study included hand MRI scans from 135 patients with seronegative RA, 190 with seropositive RA, 177 with PsA, and 147 with psoriasis. The performance was judged on the basis of area under the receiver operating characteristics curve (AUROC) with and without input of clinical characteristics. Patients who had psoriasis without clinical arthritis were included as a control population.
The AUROC for accuracy was 75% for seropositive RA relative to PsA, 74% for seronegative RA relative to PsA, and 67% for seropositive relative to seronegative RA. Of the patients who had psoriasis without arthritis, 98% were classified as PsA and 2% as RA.
Subsequent to the classification of the patients with psoriasis, 14 of the 147 (9.5%) have developed PsA so far over a relatively short follow-up. All of these were among those identified as PsA by neural network evaluation of the hand MRIs.
This suggests that “a PsA-like pattern may be present early in the course of psoriatic disease,” Dr. Simon said.
In the groups with joint disease, who had mean ages ranging from 56 to 65, the mean disease durations were 2.6 years for those with seropositive RA, 1.3 years for those with seronegative RA, and 0.8 years for those with PsA. The patients with psoriasis were younger (mean age, 40.5 years) but had a longer disease duration (mean 4.2 years).
All of the MRI sequences were relevant for classification, but contrast did not appear to help with accuracy.
“If the images with contrast enhancement were deleted, the loss of performance was only marginal,” Dr. Simon reported.
The accuracy of neural networks increases with data, making it likely that further refinements in methodology will lead to a greater degree of accuracy, according to Dr. Simon. While the methodology is not yet ready for routine use in the clinic, the study demonstrates that neural network analysis of hand MRI to distinguish forms of arthritis “is possible.” Further studies are planned toward the goal of creating a viable clinical tool.
“Of course, if we could create an accurate tool with ultrasound, this would be even more practical,” said Dr. Simon, recognizing the value of an office tool, but he cautioned that this would be far more challenging.
“The precision of MRI is an important factor for effective neural network training,” he said.
Utility: ‘In challenging cases if the accuracy improves’?
A viable method for objectively and rapidly distinguishing inflammatory joint diseases, particularly in patients with an ambiguous clinical presentation, is an unmet need, according to Philip J. Mease, MD, director of rheumatology research at Swedish Medical Center, Seattle.
Although the data presented are promising, Dr. Mease said in an interview that he believes there is a fair amount of work to be done before imaging analysis based on deep learning makes its way into routine clinical care. He is also hoping for methods to distinguish RA from PsA that are easier and less expensive, such as serum biomarkers. However, he agreed that a MRI-based tool could be useful when differentiating disease that is challenging.
“MRI is an expensive way for routine classification of disease, but this approach could be useful in challenging cases if the accuracy improves,” he said.
Meanwhile, other clinical researchers might want to test the principle. “You can try it,” said Dr. Simon, who reported that his team has made the methodology publicly available.
Dr. Simon reported no conflicts of interest. Dr. Mease reported financial relationships with more than 10 pharmaceutical companies, most of which make products used for the treatment of inflammatory joint diseases.
Hand images are sufficient
Hand images are sufficient
NEW YORK – On the basis of MRI images of the hand, a neural network has been trained to distinguish seronegative and seropositive rheumatoid arthritis (RA) from psoriatic arthritis (PsA) as well as from each other, according to a study that was presented at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.
In the work so far, the neural network was correct about 70% of the time in the absence of any further clinical analyses, according to David Simon, MD, a rheumatologist in the department of internal medicine at Friedrich-Alexander University, Erlangen, Germany.
Previous to this work, “there has been no study that has exclusively used hand MRI data and deep learning without requiring further expert input for the classification of arthritides,” Dr. Simon said.
In fact, when demographic and clinical data were added, there was no improvement in the performance of patient classification relative to the deep learning classification alone, according to the data presented by Dr. Simon.
The images were evaluated with residual neural networks (ResNet), which represents a sophisticated form of deep learning to facilitate the flow of information across the network layers as they form to improve accuracy in their ability to distinguish one form of disease from the other. The training was performed on images from the T1 coronal, T2 corona1, T1 coronal fat suppressed with contrast, T1 axial fat suppressed with contrast, and T2 fat suppressed axial sequences.
The study included hand MRI scans from 135 patients with seronegative RA, 190 with seropositive RA, 177 with PsA, and 147 with psoriasis. The performance was judged on the basis of area under the receiver operating characteristics curve (AUROC) with and without input of clinical characteristics. Patients who had psoriasis without clinical arthritis were included as a control population.
The AUROC for accuracy was 75% for seropositive RA relative to PsA, 74% for seronegative RA relative to PsA, and 67% for seropositive relative to seronegative RA. Of the patients who had psoriasis without arthritis, 98% were classified as PsA and 2% as RA.
Subsequent to the classification of the patients with psoriasis, 14 of the 147 (9.5%) have developed PsA so far over a relatively short follow-up. All of these were among those identified as PsA by neural network evaluation of the hand MRIs.
This suggests that “a PsA-like pattern may be present early in the course of psoriatic disease,” Dr. Simon said.
In the groups with joint disease, who had mean ages ranging from 56 to 65, the mean disease durations were 2.6 years for those with seropositive RA, 1.3 years for those with seronegative RA, and 0.8 years for those with PsA. The patients with psoriasis were younger (mean age, 40.5 years) but had a longer disease duration (mean 4.2 years).
All of the MRI sequences were relevant for classification, but contrast did not appear to help with accuracy.
“If the images with contrast enhancement were deleted, the loss of performance was only marginal,” Dr. Simon reported.
The accuracy of neural networks increases with data, making it likely that further refinements in methodology will lead to a greater degree of accuracy, according to Dr. Simon. While the methodology is not yet ready for routine use in the clinic, the study demonstrates that neural network analysis of hand MRI to distinguish forms of arthritis “is possible.” Further studies are planned toward the goal of creating a viable clinical tool.
“Of course, if we could create an accurate tool with ultrasound, this would be even more practical,” said Dr. Simon, recognizing the value of an office tool, but he cautioned that this would be far more challenging.
“The precision of MRI is an important factor for effective neural network training,” he said.
Utility: ‘In challenging cases if the accuracy improves’?
A viable method for objectively and rapidly distinguishing inflammatory joint diseases, particularly in patients with an ambiguous clinical presentation, is an unmet need, according to Philip J. Mease, MD, director of rheumatology research at Swedish Medical Center, Seattle.
Although the data presented are promising, Dr. Mease said in an interview that he believes there is a fair amount of work to be done before imaging analysis based on deep learning makes its way into routine clinical care. He is also hoping for methods to distinguish RA from PsA that are easier and less expensive, such as serum biomarkers. However, he agreed that a MRI-based tool could be useful when differentiating disease that is challenging.

New algorithm for initial PsA treatment choice is driven by T-cell behavior
T-cell behavior
Biologic selection is cytokine based
NEW YORK – An algorithm in development for psoriatic arthritis (PsA) is showing promise for directing patients to the biologic with the greatest likelihood of producing disease control, according to a proof-of-concept study presented at the annual meeting of the Group for Research and Assessment of Psoriasis and Psoriatic Arthritis.
“Our technique involves a more precise functional assay showing exact T-cell behavior, compared to the previous assessments that only analyzed cellular phenotypes,” reported Gizem Ayan, MD, a fellow in rheumatology at Hacettepe University Faculty of Medicine, Ankara, Turkey.
The concept of precision medicine in PsA as well as other autoimmune diseases is not new. Phenotypes and biomarkers have already shown potential for guiding treatment, according to Dr. Ayan, but she said none are yet guideline recommended or proven to improve patient outcomes.
The principle of the new algorithm that she and her coinvestigators are pursing is based on immunophenotype analysis conducted with a flow-cytometric cytokine secretion assay (FCCSA). In the protocol, monocytes obtained from peripheral blood undergo activation before an FCCSA to distinguish patients by their T-cell behavior.
The treatment decision tree is based on median ratios of tumor necrosis factor (TNF)-alpha, interleukin (IL)–22, IL-17, and interferon-gamma expression among CD4+ and CD8+ cells. Based on a yes-or-no response to specific immune patterns, the patient is funneled to a biologic that inhibits a dominant cytokine.
The proof-of-concept study, which enrolled 8 patients with PsA who were naive to conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) and 11 patients with PsA who were naive to biologic DMARDs (bDMARDs), was designed to demonstrate feasibility. It did not test clinical benefit, but it did show that immunophenotyping with this methodology can be performed efficiently.
“From the time a blood sample is obtained, the method provided results within 24 hours,” according to Dr. Ayan, who is now planning a randomized trial to test the ability of the algorithm to improve clinical outcomes.
In the decision tree, there are five yes-no pathways to a treatment choice. The first step of the algorithm is to test the ratio of TNF-alpha to interferon-gamma CD4+ T cells. A “yes’ response is produced if the ratio is greater than or equal to 2. These patients are then evaluated for the ratio of TNF-alpha to interferon-gamma CD8+ T cells. A yes response is produced if the ratio is greater than or equal to 0.5. If yes, they are candidates for a TNF-alpha inhibitor. If no, they are directed to an IL-12/23 inhibitor.
If the answer at the first decision point in the algorithm is a “no,” meaning they do not have a TNF-alpha to interferon-gamma CD4+ ratio of 2 or higher, they are evaluated for percentage of CD4+ T cells expressing IL-22 or IL-17. Is it greater than or equal to 2%? If the answer is “no,” they are candidates for an IL-12/23 inhibitor.
If “yes,” they are evaluated for percentage of IL-22 to IL-17 CD4+. If the IL-22 CD4+ percentage is lower than the IL-17 CD4+ percentage, meaning a “yes” to this decision point, they are directed to an IL-17 inhibitor. If the answer at this decision point is “no,” they are directed to an IL-12/23 inhibitor.
Prior to enrollment in this proof-of-concept study, 10 of the bDMARD patients were scheduled to receive an anti-TNF drug and 1 was scheduled to receive an IL-12/23 inhibitor. On the basis of this algorithm, only 5 patients were directed to an anti-TNF drug. Of the remaining, 5 were directed to an IL-17 inhibitor, and 1 was directed to an IL-12/23 inhibitor.
All 19 participants in the proof-of-concept study had peripheral arthritis; their median age was 45 years. Approximately 90% had skin lesions. Axial involvement was present in only one patient. Based on these and other characteristics and the median ratios of the cytokines measured, Dr. Ayan called this a representative population.
Based on the feasibility of this method for subtyping patients by T-cell behavior to guide drug selection, Dr. Ayan anticipates pursuing the additional steps that would show the algorithm makes a difference to patient care, including such adjunctive benefits as more cost-effective treatment selection.
“We aim to develop a treatment decision algorithm that can be implemented in daily practice,” Dr. Ayan said.
Is peripheral blood sampling adequate?
In addition to saying that the algorithm will need to prove that it alters outcomes, Samuel Tzen-yue Hwang, MD, PhD, professor and chair of the department of dermatology at the University of California, Davis, Sacramento, pointed out some potential practical issues.
“Flow cytometry is not typically available as a rapid throughput, and the cost is high,” he said. Moreover, he remains skeptical about performing this algorithm on the basis of peripheral blood samples.
“It is debatable that looking at peripheral cells would provide adequate information about what is taking place at sites of inflammation,” he said. Although it would “be fantastic” to develop an algorithm that required only a peripheral blood sample, he pointed out that “only a fraction of these cells is relevant” to disease activity.
Aspirating fluid from an involved joint “might be more useful,” but it is more work, he added. Yet, Dr. Hwang acknowledged that this approach is intriguing. He agreed that there is considerable heterogeneity among patients with PsA in their response to specific biologics, and a method to better direct patients to the treatment most likely to elicit a response is needed.
Dr. Ayan and Dr. Hwang reported no potential conflicts of interest.

Physicians urged to write indications on drug scripts as methotrexate users face new barriers with SCOTUS decision
.
The Court’s 5-4 decision in Dobbs v. Jackson Women’s Health Organization, which halted abortion procedures across the country, also appears to be affecting certain drug regimens. Reports have emerged that pharmacies are denying access to methotrexate (MTX), a drug often used in patients with arthritis or cancer, as well as psoriasis and other skin diseases. In very high doses, MTX it is used to terminate an ectopic pregnancy after miscarriage. The drug can also lead to birth defects.
“It’s happening all over,” Donald Miller, PharmD, professor of pharmacy practice at North Dakota State University, Fargo, said in an interview. “Pharmacists are reluctant to dispense it, and rheumatologists are reluctant to prescribe it because they’re afraid of going to jail.”
Becky Schwartz, a patient who takes MTX for lupus, recently tweeted that her physician’s office stopped prescribing the drug because it is considered an abortifacient. “I had care that made my disabled life easier, and [the Supreme Court] took that from me,” Ms. Schwartz wrote.
Prior to the Supreme Court’s ruling, physicians were concerned about the impact an overturning of the 1973 law would have on patient access to MTX and other prescription medications with abortifacient properties. Doctors in general are becoming afraid of prescribing anything that’s a teratogen, said Dr. Miller.
MTX is used far more often for autoimmune disease than as an abortifacient, said rheumatologist Kristen Young, MD, clinical assistant professor at the University of Arizona College of Medicine, Phoenix. It’s a slippery slope if states reacting to the Supreme Court ruling start regulating oral abortifacients, she added. Specifically, this will have a significant impact on patients with rheumatic disease.
Texas pharmacies target two drugs
MTX denials have caught the attention of health care organizations. “Uncertainty in financial and criminal liability for health care professionals in certain state laws and regulations are possibly compromising continuity of care and access [to] medications proven to be safe and effective by the Food and Drug Administration for these indications,” warned the American Pharmacists Association (APhA) in a statement to this news organization.
The APhA said that it was monitoring this situation to assess the effect on patients and pharmacists.
The Arthritis Foundation was made aware of challenges from patients in accessing their MTX prescription for managing their arthritis and shared a statement on the Foundation’s website.
In Texas, pharmacists can refuse to fill scripts for misoprostol and MTX, a combination used for medical abortions. According to the foundation, “Already there are reports that people in Texas who miscarry or take methotrexate for arthritis [are] having trouble getting their prescriptions filled.”
MTX, approved by the FDA in 1985, “is the absolute cornerstone of rheumatoid arthritis. We cannot deny our patients this incredibly valuable drug,” said John Reveille, MD, vice-chair for the department of medicine at the University of Texas McGovern School of Medicine and a member of the Arthritis Foundation expert panel, in an interview.
“While it’s true that methotrexate can be lethal to the fetus, misoprostol is much more likely to cause a spontaneous abortion, and the combination is especially effective,” he said.
“If you look at Cochrane clinical studies, the dose of misoprostol contained in certain combinations with NSAIDs [nonsteroidal anti-inflammatory drugs] can induce spontaneous abortions. It’s surprising that pharmacists are targeting methotrexate, an essential drug in arthritis treatment, when there are medications available that do not have this benefit that can by themselves cause loss of the fetus, such as mifepristone,” added Dr. Reveille.
The Dobbs ruling could also affect the ability of oncologists to provide lifesaving cancer care, according to Jason Westin, MD, an oncologist at the University of Texas MD Anderson Cancer Center in the department of lymphoma and myeloma.
“We have heard of medications with multiple indications, such as methotrexate, not being dispensed by pharmacies due to confusion regarding the intended use and potential consequences for the health care team,” he said in an interview.
Conflicting laws pose challenges for physicians
In North Dakota, inconsistencies in several laws are making it difficult for physicians and pharmacists to make decisions. “Lots of confusion can result when people pass laws against abortion. There’s sometimes no insight into the ramifications of those laws,” said Dr. Miller.
North Dakota approved a trigger law several years ago that makes abortion illegal 30 days after an overturning of Roe. However, another law that regulates abortion conflicts with the trigger law. “Some of the language will need clarification in the next legislative session,” he said.
APhA and other pharmacy associations strongly favor not interfering with the doctor- or pharmacist-patient relationship. The law needs to defer to appropriate care between doctor and patient, said Dr. Miller. State pharmacy associations in North Dakota are working with legislatures to clarify any exceptions in the law, he added.
Arizona lawmakers are trying to reconcile two abortion laws on the books. One, based on an 1864 territorial law, deems abortion illegal. In addition, a newly approved law bans abortions after 15 weeks. The latter will go into effect in September 2022. In both laws, a risk to the mother’s life is the only exception for abortion, said Dr. Young.
Denials aren’t widespread
Not all doctors are seeing MTX denials, but they’re worried about the future. “To date, we have not encountered difficulty in obtaining methotrexate based upon state abortion restrictions but are concerned that this could occur and result in dangerous delays in care,” said Dr. Westin.
Dr. Reveille, who practices rheumatology in Houston, has not yet received any complaints from patients. Things may be different in more rural parts of Texas, where pharmacists could be denying prescriptions based on religious issues, he offered.
It’s a little soon to see what repercussions may result from the Supreme Court ruling and state actions, said Dr. Reveille. “In Texas, we’re a bit ahead of the tidal wave.”
Access problems also haven’t shown up at the university clinic where Dr. Young practices. “In Arizona, it’s unclear if there would be a legal basis to refuse a person methotrexate on the basis that it can be used as an abortifacient,” she said.
Specificity is key in writing Rx scripts
Physicians can make things easier for patients by writing the indication and dose for the drug on the prescription slip. For example, a 10-mg script for MTX is not going to be used for an abortion, said Dr. Miller.
Rheumatologists in Texas have been doing this for some time, even before the Supreme Court ruling, said Fehmida Zahabi, MD, FACR, president of the Society of Texas Association of Rheumatology. For MTX prescriptions in premenopausal women, “patients are told their doctor needs to call the pharmacist. In the small print, we are asked to give a diagnosis to make sure we aren’t using it to terminate pregnancies,” said Dr. Zahabi.
She further noted that if the diagnosis is already indicated on the script, pharmacies generally won’t give patients a hard time.
Patients can also ask their physicians for a letter of medical necessity that confirms a drug’s use for a specific medical condition.
Mail order is another option if a local pharmacy won’t fill a prescription, said Dr. Miller. “This is legal unless a state makes it illegal to send an abortifacient across state lines,” he added.
Many medications used in rheumatic diseases are harmful in pregnancy, and it’s important to routinely discuss pregnancy risk and planning in the rheumatology clinic, said Dr. Young. This should include a thorough discussion and referral for long-acting reversible contraception in most cases, she suggested.
Actions at the federal, state level
President Joe Biden recently signed an executive order prompting federal regulators to protect access to medication abortions, among other steps to safeguard access to reproductive services.
In a statement on Twitter, the American College of Rheumatology (ACR) said that it was “ ... following this issue closely to determine if rheumatology providers and patients are experiencing any widespread difficulty accessing methotrexate or if any initial disruptions are potentially temporary and due to the independent actions of pharmacists trying to figure out what is and isn’t allowed where they practice.”
ACR has assembled a task force of medical and policy experts to determine the best course of action for patients.
The Arthritis Foundation also continues to monitor the situation, encouraging patients to call its hotline, said Steven Schultz, director of state legislative affairs, in an interview.
“We are analyzing how medication abortion could cause confusion on the part of providers or pharmacists dispensing the medication and what this means for specific patients,” said Mr. Schultz. Through a survey, the foundation hopes to get a better idea of what’s going on in the states at a macro level.
This may take some time, as states go through a process of lawsuits, injunctions, or coming into session to do something that may affect access to MTX, said Mr. Schultz.
Being involved in local advocacy is more important than ever, stressed Dr. Young. “Additionally, being plugged into what the ACR and other advocacy groups are doing on the national level is helpful as well to know the status of these medication access issues.”
Rheumatologists have a unique voice in this discussion, she added. “We guide our patients to stability for a safe pregnancy, and even with careful planning, we see patients who become critically ill during pregnancy and require lifesaving treatment, which at times can mean an abortion is necessary.”
Oncologists also advocate for their patients on a regular basis to make sure they have access to the care they need, said Dr. Westin. This situation with Roe is no different, he added. “We will continue to use our unique expertise to advocate for policies that assure access to high-quality, evidence-based care – and to help our patients overcome barriers that may interfere.”
Dr. Reveille participated on an advisory board with Eli Lilly in October 2021.

The Court’s 5-4 decision in Dobbs v. Jackson Women’s Health Organization, which halted abortion procedures across the country, also appears to be affecting certain drug regimens. Reports have emerged that pharmacies are denying access to methotrexate (MTX), a drug often used in patients with arthritis or cancer, as well as psoriasis and other skin diseases. In very high doses, MTX it is used to terminate an ectopic pregnancy after miscarriage. The drug can also lead to birth defects.
“It’s happening all over,” Donald Miller, PharmD, professor of pharmacy practice at North Dakota State University, Fargo, said in an interview. “Pharmacists are reluctant to dispense it, and rheumatologists are reluctant to prescribe it because they’re afraid of going to jail.”
Becky Schwartz, a patient who takes MTX for lupus, recently tweeted that her physician’s office stopped prescribing the drug because it is considered an abortifacient. “I had care that made my disabled life easier, and [the Supreme Court] took that from me,” Ms. Schwartz wrote.
Prior to the Supreme Court’s ruling, physicians were concerned about the impact an overturning of the 1973 law would have on patient access to MTX and other prescription medications with abortifacient properties. Doctors in general are becoming afraid of prescribing anything that’s a teratogen, said Dr. Miller.
MTX is used far more often for autoimmune disease than as an abortifacient, said rheumatologist Kristen Young, MD, clinical assistant professor at the University of Arizona College of Medicine, Phoenix. It’s a slippery slope if states reacting to the Supreme Court ruling start regulating oral abortifacients, she added. Specifically, this will have a significant impact on patients with rheumatic disease.
Texas pharmacies target two drugs
MTX denials have caught the attention of health care organizations. “Uncertainty in financial and criminal liability for health care professionals in certain state laws and regulations are possibly compromising continuity of care and access [to] medications proven to be safe and effective by the Food and Drug Administration for these indications,” warned the American Pharmacists Association (APhA) in a statement to this news organization.
The APhA said that it was monitoring this situation to assess the effect on patients and pharmacists.
The Arthritis Foundation was made aware of challenges from patients in accessing their MTX prescription for managing their arthritis and shared a statement on the Foundation’s website.
In Texas, pharmacists can refuse to fill scripts for misoprostol and MTX, a combination used for medical abortions. According to the foundation, “Already there are reports that people in Texas who miscarry or take methotrexate for arthritis [are] having trouble getting their prescriptions filled.”
MTX, approved by the FDA in 1985, “is the absolute cornerstone of rheumatoid arthritis. We cannot deny our patients this incredibly valuable drug,” said John Reveille, MD, vice-chair for the department of medicine at the University of Texas McGovern School of Medicine and a member of the Arthritis Foundation expert panel, in an interview.
“While it’s true that methotrexate can be lethal to the fetus, misoprostol is much more likely to cause a spontaneous abortion, and the combination is especially effective,” he said.
“If you look at Cochrane clinical studies, the dose of misoprostol contained in certain combinations with NSAIDs [nonsteroidal anti-inflammatory drugs] can induce spontaneous abortions. It’s surprising that pharmacists are targeting methotrexate, an essential drug in arthritis treatment, when there are medications available that do not have this benefit that can by themselves cause loss of the fetus, such as mifepristone,” added Dr. Reveille.
The Dobbs ruling could also affect the ability of oncologists to provide lifesaving cancer care, according to Jason Westin, MD, an oncologist at the University of Texas MD Anderson Cancer Center in the department of lymphoma and myeloma.
“We have heard of medications with multiple indications, such as methotrexate, not being dispensed by pharmacies due to confusion regarding the intended use and potential consequences for the health care team,” he said in an interview.
Conflicting laws pose challenges for physicians
In North Dakota, inconsistencies in several laws are making it difficult for physicians and pharmacists to make decisions. “Lots of confusion can result when people pass laws against abortion. There’s sometimes no insight into the ramifications of those laws,” said Dr. Miller.
North Dakota approved a trigger law several years ago that makes abortion illegal 30 days after an overturning of Roe. However, another law that regulates abortion conflicts with the trigger law. “Some of the language will need clarification in the next legislative session,” he said.
APhA and other pharmacy associations strongly favor not interfering with the doctor- or pharmacist-patient relationship. The law needs to defer to appropriate care between doctor and patient, said Dr. Miller. State pharmacy associations in North Dakota are working with legislatures to clarify any exceptions in the law, he added.
Arizona lawmakers are trying to reconcile two abortion laws on the books. One, based on an 1864 territorial law, deems abortion illegal. In addition, a newly approved law bans abortions after 15 weeks. The latter will go into effect in September 2022. In both laws, a risk to the mother’s life is the only exception for abortion, said Dr. Young.
Denials aren’t widespread
Not all doctors are seeing MTX denials, but they’re worried about the future. “To date, we have not encountered difficulty in obtaining methotrexate based upon state abortion restrictions but are concerned that this could occur and result in dangerous delays in care,” said Dr. Westin.
Dr. Reveille, who practices rheumatology in Houston, has not yet received any complaints from patients. Things may be different in more rural parts of Texas, where pharmacists could be denying prescriptions based on religious issues, he offered.
It’s a little soon to see what repercussions may result from the Supreme Court ruling and state actions, said Dr. Reveille. “In Texas, we’re a bit ahead of the tidal wave.”
Access problems also haven’t shown up at the university clinic where Dr. Young practices. “In Arizona, it’s unclear if there would be a legal basis to refuse a person methotrexate on the basis that it can be used as an abortifacient,” she said.
Specificity is key in writing Rx scripts
Physicians can make things easier for patients by writing the indication and dose for the drug on the prescription slip. For example, a 10-mg script for MTX is not going to be used for an abortion, said Dr. Miller.
Rheumatologists in Texas have been doing this for some time, even before the Supreme Court ruling, said Fehmida Zahabi, MD, FACR, president of the Society of Texas Association of Rheumatology. For MTX prescriptions in premenopausal women, “patients are told their doctor needs to call the pharmacist. In the small print, we are asked to give a diagnosis to make sure we aren’t using it to terminate pregnancies,” said Dr. Zahabi.
She further noted that if the diagnosis is already indicated on the script, pharmacies generally won’t give patients a hard time.
Patients can also ask their physicians for a letter of medical necessity that confirms a drug’s use for a specific medical condition.
Mail order is another option if a local pharmacy won’t fill a prescription, said Dr. Miller. “This is legal unless a state makes it illegal to send an abortifacient across state lines,” he added.
Many medications used in rheumatic diseases are harmful in pregnancy, and it’s important to routinely discuss pregnancy risk and planning in the rheumatology clinic, said Dr. Young. This should include a thorough discussion and referral for long-acting reversible contraception in most cases, she suggested.
Actions at the federal, state level
President Joe Biden recently signed an executive order prompting federal regulators to protect access to medication abortions, among other steps to safeguard access to reproductive services.

Pain and photophobia
On the basis of the patient's medical history and presentation, this is probably a case of uveitis, a common extra-articular manifestation of psoriatic disease. In fact, the presence of uveitis can help distinguish PsA from osteoarthritis. Uveitis is characterized by inflammation of the uvea tract, with the retina, optic nerve, vitreous body, and sclera potentially becoming inflamed as well. Among patients with PsA, the prevalence of uveitis rises with ongoing disease duration, though the condition may also precede the development of PsA in patients with psoriasis, and is common among patients with severe psoriatic disease in Western and Asian populations. Overall, the prevalence of uveitis has been estimated to be 6%-9%. HLA-B27 genotype is strongly associated with uveitis in patients with concomitant PsA.
Symptoms of uveitis, as seen in the present case, include blurred vision, photophobia, pain, and ciliary flush. The condition is classified as anterior, intermediate, posterior, or panuveitis, with the majority of cases diagnosed as anterior. In anterior uveitis, the inflamed pupil may become constricted or take on an irregular shape caused by iris adhesions to the anterior lens capsule. Uveitis in PsA is bilateral and has a chronic relapsing course. Onset is typically insidious.
Workup for uveitis should comprise visual acuity testing, slit lamp biomicroscopy, measurement of intraocular pressures, and a dilated eye exam. Conditions in the differential which threaten a patient's sight include retinal vasculitis, vitritis, cystoid macular edema, Behçet disease, and tubulo-interstitial nephritis. Other autoimmune diseases which can cause uveitis with systemic manifestations (multiple sclerosis, sarcoidosis, lupus) should be investigated. Infectious causes must also be eliminated. However, considering this patient's history of psoriatic disease, uveitis should be highly suspected.
Uveitis demands urgent treatment to control ocular inflammation. Tumor necrosis factor (TNF) inhibitors are the recommended first-line and second-line treatment for PsA, including in patients with complications such as uveitis. However, etanercept should not be used as it is less effective than adalimumab or other TNF inhibitors for uveitis. Because uveitis may sometimes respond to MTX therapy, patients with severe PsA may use a biologic agent in combination with MTX if they have had a partial response to current MTX therapy, as recommended by the American College of Rheumatology.

A 48-year-old male patient presents with blurred vision, pain, and photophobia. He recently had a routine visit with an ophthalmologist, which was normal. The affected pupil appears irregular in shape. The anterior chamber appears foggy. Local ciliary flush is observed on slit lamp exam. The physical examination is also notable for axial arthropathy. The patient has an 11-year history of moderate to severe psoriatic arthritis (PsA) which he typically manages with methotrexate (MTX) therapy, to which he has had a partial response. He was initially diagnosed when he presented with worsening psoriasis and enthesitis on the insertion sites of the plantar fascia, as well as dactylitis.
Zoster vaccination does not appear to increase flare risk in patients with immune-mediated inflammatory disease
, according to research published in Arthritis & Rheumatology.
The authors of the study noted that individuals with IMIDs are at increased risk for herpes zoster and related complications, including postherpetic neuralgia, and that vaccination has been recommended for certain groups of patients with rheumatoid arthritis, inflammatory bowel disease, and psoriasis, by the American College of Rheumatology and other professional organizations for individuals aged 50 and older.
The study investigators used medical claims from IBM MarketScan, which provided data on patients aged 50-64 years, and data from the Centers for Medicare and Medicaid Services’ Medicare on patients aged 65 and older.
They defined presumed flares in three ways: hospitalization/emergency department visits for IMIDs, steroid treatment with a short-acting oral glucocorticoid, or treatment with a parenteral glucocorticoid injection. The investigators conducted a self-controlled case series (SCCS) analysis to examine any temporal link between the RZV and disease flares.
Among enrollees with IMIDs, 14.8% of the 55,654 patients in the MarketScan database and 43.2% of the 160,545 patients in the Medicare database received at least one dose of RZV during 2018-2019. The two-dose series completion within 6 months was 76.6% in the MarketScan group (age range, 50-64 years) and 85.4% among Medicare enrollees (age range, 65 years and older). In the SCCS analysis, 10% and 13% of patients developed flares in the control group as compared to 9%, and 11%-12% in the risk window following one or two doses of RZV among MarketScan and Medicare enrollees, respectively.
Based on these findings, the investigators concluded there was no statistically significant increase in flares subsequent to RZV administration for any IMID in either patients aged 50-64 years or patients aged 65 years and older following the first dose or second dose.
Nilanjana Bose, MD, a rheumatologist with Lonestar Rheumatology, Houston, Texas, who was not involved with the study, said that the research addresses a topic where there is uneasiness, namely vaccination in patients with IMIDs.
“Anytime you are vaccinating a patient with an autoimmune disease, especially one on a biologic, you always worry about the risk of flares,” said Dr. Bose. “Any time you tamper with the immune system, there is a risk of flares.”
The study serves as a clarification for the primary care setting, said Dr. Bose. “A lot of the time, the shingles vaccine is administered not by rheumatology but by primary care or through the pharmacy,” she said. “This study puts them [primary care physicians] at ease.”
Findings from the study reflect that most RZV vaccinations were administered in pharmacies.
One of the weaknesses of the study is that the investigators did not include patients younger than 50 years old, said Dr. Bose. “It would have been nice if they could have looked at younger patients,” she said. “We try to vaccinate all our [immunocompromised] adult patients, even the younger ones, because they are also at risk for shingles.”
Given that there are increasing options of medical therapies in rheumatology that are immunomodulatory, the subject of vaccination for patients is often one of discussion, added Dr. Bose.
Arthur Kavanaugh, MD, professor of medicine, University of California San Diego (UCSD), La Jolla, Calif., and director of the Center for Innovative Therapy in the UCSD Division of Rheumatology, Allergy, and Immunology, told this news organization that a strength of the study is its large numbers of patients but noted the shortcoming of using claims data. “Claims data has inherent limitations, such as the lack of detailed granular data on the patients,” wrote Dr. Kavanaugh, who was not involved with the study. He described this investigation as “really about the first evidence that I am aware of addressing this issue.”
No funding source was listed. One author disclosed having received research grants and consulting fees received from Pfizer and GSK for unrelated work; the other authors had no disclosures. Dr. Bose and Dr. Kavanaugh had no relevant disclosures.

Among enrollees with IMIDs, 14.8% of the 55,654 patients in the MarketScan database and 43.2% of the 160,545 patients in the Medicare database received at least one dose of RZV during 2018-2019. The two-dose series completion within 6 months was 76.6% in the MarketScan group (age range, 50-64 years) and 85.4% among Medicare enrollees (age range, 65 years and older). In the SCCS analysis, 10% and 13% of patients developed flares in the control group as compared to 9%, and 11%-12% in the risk window following one or two doses of RZV among MarketScan and Medicare enrollees, respectively.
Based on these findings, the investigators concluded there was no statistically significant increase in flares subsequent to RZV administration for any IMID in either patients aged 50-64 years or patients aged 65 years and older following the first dose or second dose.
Nilanjana Bose, MD, a rheumatologist with Lonestar Rheumatology, Houston, Texas, who was not involved with the study, said that the research addresses a topic where there is uneasiness, namely vaccination in patients with IMIDs.
“Anytime you are vaccinating a patient with an autoimmune disease, especially one on a biologic, you always worry about the risk of flares,” said Dr. Bose. “Any time you tamper with the immune system, there is a risk of flares.”
The study serves as a clarification for the primary care setting, said Dr. Bose. “A lot of the time, the shingles vaccine is administered not by rheumatology but by primary care or through the pharmacy,” she said. “This study puts them [primary care physicians] at ease.”
Findings from the study reflect that most RZV vaccinations were administered in pharmacies.
One of the weaknesses of the study is that the investigators did not include patients younger than 50 years old, said Dr. Bose. “It would have been nice if they could have looked at younger patients,” she said. “We try to vaccinate all our [immunocompromised] adult patients, even the younger ones, because they are also at risk for shingles.”
Given that there are increasing options of medical therapies in rheumatology that are immunomodulatory, the subject of vaccination for patients is often one of discussion, added Dr. Bose.
Arthur Kavanaugh, MD, professor of medicine, University of California San Diego (UCSD), La Jolla, Calif., and director of the Center for Innovative Therapy in the UCSD Division of Rheumatology, Allergy, and Immunology, told this news organization that a strength of the study is its large numbers of patients but noted the shortcoming of using claims data. “Claims data has inherent limitations, such as the lack of detailed granular data on the patients,” wrote Dr. Kavanaugh, who was not involved with the study. He described this investigation as “really about the first evidence that I am aware of addressing this issue.”

The authors of the study noted that individuals with IMIDs are at increased risk for herpes zoster and related complications, including postherpetic neuralgia, and that vaccination has been recommended for certain groups of patients with rheumatoid arthritis, inflammatory bowel disease, and psoriasis, by the American College of Rheumatology and other professional organizations for individuals aged 50 and older.
The study investigators used medical claims from IBM MarketScan, which provided data on patients aged 50-64 years, and data from the Centers for Medicare and Medicaid Services’ Medicare on patients aged 65 and older.
They defined presumed flares in three ways: hospitalization/emergency department visits for IMIDs, steroid treatment with a short-acting oral glucocorticoid, or treatment with a parenteral glucocorticoid injection.

Large study reaffirms rare risk of TNF inhibitor–induced psoriasis in patients with RA, IBD
according to a new study published in JAMA Dermatology.
Despite this finding, the authors of the large Danish nationwide cohort study noted that TNFi-induced psoriasis is still a rare adverse event. “Practitioners and patients should be aware and observant of the potential for TNFi-associated psoriasis during TNFi treatment but keep in mind that the absolute risk appears to be low,” David Thein, MB, of the department of dermatology at Bispebjerg Hospital, University of Copenhagen, and colleagues wrote in the study.
They analyzed 109,085 patients with RA and IBD enrolled in Danish national registries between 1995 and 2018 without a previous diagnosis of psoriasis, who received either TNFi (20,910 patients) or conventional treatments (108,024 patients) and were followed for 5 years. They were a mean of 50 years old when they started treatment, 62% were women, with 87.8% of patients in the TNFi group receiving prior conventional therapy and 1% of patients in the conventional therapy group receiving prior TNFi treatment.
The investigators assessed the risk of developing any psoriasis, nonpustular psoriasis, and pustular psoriasis in the two groups using ICD-10 codes as well as a record of two consecutive prescriptions for topical vitamin D analogs.
Overall, 1,471 patients (1.4%) developed psoriasis of any type; 1,332 had non-pustular psoriasis, 127 had palmoplantar pustulosis, and 12 had generalized pustulosis.
The incidence rate of developing any psoriasis was 3.0 per 1,000 patient-years (95% confidence interval, 2.9-3.2) for patients receiving conventional therapy and 7.8 per 1,000 patient-years (95% CI, 7.5-8.9) for patients receiving TNFi treatment. Compared with conventional treatment, the risk of developing nonpustular psoriasis was twofold higher among patients receiving TNFi treatment (hazard ratio, 2.12; 95% CI, 1.87-2.40; P < .001). The risk of developing pustular psoriasis was more than sixfold higher among those on a TNFi (HR, 6.50; 95% CI, 4.60-9.23; P < .001).
Dr. Thein and colleagues estimated that the exposure needed to harm 1 additional patient was 241 patient-years for any psoriasis type, 342 patient-years for nonpustular psoriasis, and 909 patient-years for pustular psoriasis, with an estimated absolute risk difference of 5 per 1,000 patient-years.
Best evidence to date on risk
Asked to comment on the study findings, Anthony Fernandez, MD, PhD, director of medical dermatology at the Cleveland Clinic, said that he applauded the researchers for performing this well-designed study to determine the risk of TNF inhibitor–induced psoriasis in patients with RA and IBD.
The strengths of the study include excluding patients with a history of psoriasis to rule out disease recurrence and having a large comparator group of patients with IBD and RA who were taking medications other than TNF inhibitors, while one limitation was the potential accuracy of the ICD-10 codes used as the basis for diagnosing psoriasis. “It’s probably closer to the truth of what the true risk is compared to studies done in the past,” he said in an interview.
Dr. Fernandez noted that the results aren’t likely to change how dermatologists, rheumatologists, or gastroenterologists practice, but the message to stay the course in initially treating TNFi-induced psoriasis also holds value. “We don’t need to change anything in our clinical practice when it comes to TNF-alpha inhibitors.”
For patients with RA or IBD who develop TNFi-induced psoriasis with disease that is well controlled with TNFi treatment, keeping them on that treatment is a priority, Dr. Fernandez explained. “The first and foremost goal is, if the TNF inhibitor is working very well to control the disease that it was prescribed for, then you exhaust your efforts to try to control the psoriasis and allow those patients to stay on the TNF inhibitor.”
In his experience, most patients with RA and IBD who develop TNFi-induced psoriasis are controlled with topical medications. Switching to another TNFi is not recommended, he noted, as patients are “likely to have that reaction with any TNF inhibitor.”
However, Dr. Fernandez said that won’t be an option for all patients with RA and IBD. “In some patients you do simply have to stop the TNF inhibitor” and try an alternative treatment with a different mechanism of action.
The cause of TNFi-induced psoriasis is still not well understood. “There certainly is evidence to support that interferon alpha production by plasmacytoid dendritic cells is playing some role in this phenomenon,” but there is “more to the story” and unanswered questions remain, Dr. Fernandez said.
What’s most interesting about this phenomenon, he added, is that “patients can develop it at any time when exposed to a TNF inhibitor.” For instance, most patients develop drug reactions within 2-3 weeks of starting a treatment, but TNFi-induced psoriasis can appear after a single dose or several years after initiating treatment.
“Why so few patients, and why is there such variability in terms of how long they’re on the TNF inhibitor before the reaction occurs?” he asked. “That really points to ... some other trigger besides exposure to the TNF inhibitor needed for the initiation of this reaction.”
He noted that it would be valuable to identify triggers – or the most likely triggers – which would be challenging, but could “potentially impact clinical practice.”
The authors reported personal and institutional relationships in the form of personal and institutional research grants, honoraria, personal fees, investigator fees paid to university, consultancies, and speaker’s bureau positions for a variety of pharmaceutical companies, data companies, hospitals, and foundations. Dr. Fernandez reported he has nonbranded speaking, consulting, and research relationships with AbbVie and Novartis; and is a consultant for UCB, Bristol-Myers Squibb, and Boehringer Ingelheim on related products.

FROM JAMA DERMATOLOGY
Commentary: Evaluating New Treatments and Cardiovascular Risk in PsA, July 2022
Inhibition of the Janus kinase-signal transducer and activator of transcription (JAK-STAT) pathway by JAK inhibitors is efficacious in psoriatic arthritis (PsA). On the basis of the results of the pivotal SELECT-PsA 1 and SELECT-PsA 2 trials, upadacitinib, a selective JAK1 inhibitor, was recently approved for the treatment of PsA. However, data on longer-term disease control is still of interest. In a post hoc analysis of SELECT-PsA 1 and SELECT-PsA 2, Mease and colleagues assessed the proportion of patients achieving low disease activity or remission, as defined by validated measures such as the Disease Activity Index in Psoriatic Arthritis, Psoriatic Arthritis Disease Activity Scores, and minimal disease activity at 24 and 56 weeks. They showed that at week 24,a higher proportion of patients receiving 15 mg upadacitinib vs placebo achieved low disease activityon the Disease Activity Index in Psoriatic Arthritis (range, 35%-48% vs 4%-16%; P< .05) and remission (range, 7%-11% vs 0%-3%; P< .05), with the responses sustained until week 56. Thus, upadacitinib provides sustained disease control in PsA and is an effective oral therapy.
Advanced targeted therapies have proven safety and efficacy over conventional therapies, often dramatically improving signs and symptoms. However, it is also desirable that such expensive therapies also show benefit in other outcomes, such as work productivity and quality of life. To evaluate work productivity and daily activity impairment and health-related quality of life in patients with inflammatory arthritis (rheumatoid arthritis, n=95;PsA,n=69, and axial spondyloarthritis, n=95) treated with golimumab, Dejaco and colleagues conducted a prospective, multicenter study in Austria. A total of 110 of these patients were followed for 24 months. At 24 months after golimumab initiation, there was significant improvement in total work productivity, presenteeism, activity impairment, and quality-of-life scores. Thus, golimumab, in addition to reducing disease activity, improved work productivity, activity, and health-related quality of life in patients with inflammatory arthritis, including PsA.
Cardiovascular disease (CVD) remains a major comorbidity in patients with PsA. This observation was once again confirmed in an observational, cross-sectional, case-control study including 207 patients with PsA and 414 matched controls from France. Degboe and colleagues demonstrated that patients with PsA had a higher prevalence of cardiovascular events and cardiovascular risk factors, such as high body mass index, triglyceride level, and hypertension, compared with controls. The proportion of patients with PsA who were estimated to have very high cardiovascular risk factors (≥10%) increased when SCORE (European Society of Cardiology Systematic Coronary Risk Evaluation) and QRISK2 (British Heart Foundation) equations considered the additional risk attributable to PsA. However, risk predictions scores such as SCORE and QRISK2 perform poorly in patients with PsA. To identify novel inflammatory and metabolic parameters associated with cardiovascular disease, Schwartz and colleagues looked at18F-fluorodeoxyglucose(FDG) PET-CT uptakeina cross-sectional analysis of a prospective study including 39 patients with biologic-treatment-naive PsA and 56 age-sex matched controls without PsA. They found that coronary artery disease (CAD) was significantly associated with visceral adiposity and FDG uptake in the bone marrow, liver, spleen, and subcutaneous adipose tissue. Thus, inflammatory and metabolic parameters, including visceral adiposity, potentially contribute to subclinical CAD in patients with PsA and may in the future be used to refine CVD risk and be targets for CAD preventive treatments.

The proportion of patients with PsA who were estimated to have very high cardiovascular risk factors (≥10%) increased when SCORE (European Society of Cardiology Systematic Coronary Risk Evaluation) and QRISK2 (British Heart Foundation) equations considered the additional risk attributable to PsA. However, risk predictions scores such as SCORE and QRISK2 perform poorly in patients with PsA. To identify novel inflammatory and metabolic parameters associated with cardiovascular disease, Schwartz and colleagues looked at18F-fluorodeoxyglucose(FDG) PET-CT uptakeina cross-sectional analysis of a prospective study including 39 patients with biologic-treatment-naive PsA and 56 age-sex matched controls without PsA. They found that coronary artery disease (CAD) was significantly associated with visceral adiposity and FDG uptake in the bone marrow, liver, spleen, and subcutaneous adipose tissue. Thus, inflammatory and metabolic parameters, including visceral adiposity, potentially contribute to subclinical CAD in patients with PsA and may in the future be used to refine CVD risk and be targets for CAD preventive treatments.
