Lower HLA-B27 positivity and heterogeneous late-onset case proportions across axial spondyloarthritis cohorts: a systematic review and meta-analysis

Comparison of the Clinical Expression of Patients with Enthesitis/Spondylitis-Related Juvenile Idiopathic Arthritis (E/SpRJIA) from Türkiye and India

Comparisons of the clinical characteristics of enthesitis/ spondylitis-related juvenile idiopathic arthritis in Türkiye and India suggest that factors beyond HLA-B27, including broader genetic, environmental, and population-specific influences, may contribute to differences in disease expression.

Very late-onset myasthenia gravis: a systematic review and meta-analysis of clinical severity and long-term outcomes.

Spondyloarthritis Research and Treatment Network Recommendations for the Referral of Adults With Chronic Back Pain and Suspected Axial Spondyloarthritis to a Rheumatologist

Objective In the United States, axial spondyloarthritis (axSpA) diagnosis is delayed up to 14 years preventing effective management. We convened a multidisciplinary clinician and patient group to develop recommendations for rheumatology referral of adults with chronic back pain. Methods Systematic review (SR) and meta‐...

Clinical Factors Associated with Diagnostic Delay in Axial Spondyloarthritis in Saudi Arabia: A Retrospective Cohort Study

Persistent features suggestive of inflammatory axial disease in patients with fibromyalgia warrant selective diagnostic reconsideration in patients with rheumatologist-confirmed axSpA.

Clinical Factors and Cumulative Smoking Burden Associated with Anti-TNF Switching in Radiographic Axial Spondyloarthritis: A Real-World Cohort Study

Background/Objectives: Anti-tumor necrosis factor (anti-TNF) switching remains common in radiographic axial spondyloarthritis (r-axSpA). We aimed to evaluate cumulative smoking burden and clinical factors associated with anti-TNF switching. Methods: This retrospective single-center cohort included 212 patients with r-a...

Occurrence and clinical course of immune checkpoint inhibitor-associated inflammatory arthritis and polymyalgia rheumatica-like syndromes: a systematic review and meta-analysis

Background Immune checkpoint inhibitor-associated inflammatory arthritis (ICI-IA) and polymyalgia rheumatica (PMR)-like syndromes are clinically important rheumatic immune-related adverse events, but definitions vary across studies. We estimated their occurrence in real-world cohorts and summarized clinical course and...
