Dr. David Pisetsky curated the research presented at ACR Convergence 2025 and answers the question “What new research on psoriatic arthritis has the potential to impact patient care or future research?”
Chronic Back Pain & axSpA
Maksymowych et al. assessed the frequency of axial spondyloarthritis (axSpA) according to extra-articular presentation and human leukocyte antigen B27 (HLA-B27) status and sought to identify features that distinguish patients with axSpA from those with non-specific back pain. Their data support recommendations that patients with chronic back pain and extra-articular features related to axSpA be screened for axSpA with MRI and referred to a rheumatologist.
Risk of IBD in Patients with Psoriasis, PsA & Ankylosing Spondylitis Starting IL-17 Inhibitors
In February A&R, Penso et al. reported on the results of their study, which explored whether patients with psoriasis, PsA and AS have a higher risk of developing IBD when treated with an IL-17 inhibitor compared with apremilast, a phosphodiesterase 4 (PDE4) inhibitor, or etanercept, a TNF inhibitor.
Gut Feeling: A Comprehensive Look at the Pathogenesis, Management & Treatment of Inflammatory Bowel Disease
Patients with autoimmune diseases, such as spondyloarthritis, are at risk of developing inflammatory bowel disease. Here are considerations for its management and treatment.
Case Report: Is It Reactive or IBD-Associated Arthritis?
Reactive arthritis is classically associated with an infectious etiology, such as Salmonella, Yersinia, Campylobacter, Chlamydia or gonorrhea. Clostridium difficile is a rare, and recently recognized, causative agent for this condition.1 Case Presentation The patient is a 21-year-old man with a past medical history significant for hereditary spherocytosis and Crohn’s disease, complicated by an anorectal fistula,…
Anti-TNF Treatment Tied to Lower Risk of Acute Arterial Events in IBD
NEW YORK (Reuters Health)—Anti-tumor necrosis factor (TNF) treatment is associated with a reduced risk of acute arterial events in patients with inflammatory bowel disease (IBD), especially men, new research shows. IBD patients face an increased risk of acute arterial events, which are also independently associated with disease activity, Julien Kirchgesner, MD, PhD, of Hospital Saint-Antoine,…
IBD Patients Who Switch from Infliximab to Biosimilar See Mixed Results
NEW YORK (Reuters Health)—Patients with inflammatory bowel disease (IBD) can safely switch from infliximab to the biosimilar CT-P13, though they may face a higher risk of clinical relapse, researchers from Spain report. Recent studies have demonstrated the effectiveness and safety of infliximab biosimilars in patients with IBD, but there are limited data about the effectiveness…
Inflammatory Spinal Disorders Common in IBD Patients
NEW YORK (Reuters Health)—Ankylosing spondylitis (AS), axial spondyloarthritis (SpA) and inflammatory back pain are common in inflammatory bowel disease (IBD) patients two decades after IBD diagnosis, according to findings from the IBSEN study1. Doctors should know IBD patients are at risk of inflammatory back problems, and refer them to a rheumatologist when appropriate, Dr. Alvilde Ossum…
