Weight Loss as a Therapeutic Goal in Psoriatic Arthritis
Psoriatic arthritis (PsA) is a complex inflammatory disease often complicated by obesity, which not only worsens disease activity but also impairs treatment response. At ACR Convergence 2025, three compelling studies spanning pharmacologic, lifestyle, and longitudinal observational data converged on a central theme: weight loss is a powerful modulator of PsA outcomes, regardless of the intervention used.

The Long View of Diagnostic Delay in Axial Spondyloarthritis
Axial spondyloarthritis (axSpA) remains a diagnostic challenge, particularly in its early stages before structural sacroiliitis is visible on imaging.

Sleep Apnea in Psoriatic Arthritis – A Wake Up Call
Fatigue is one of the most disabling symptoms in psoriatic arthritis (PsA), yet its causes are often underexplored. At ACR 2025, Abstract #0549, a possible hidden contributor was studied: obstructive sleep apnea (OSA).

ICYMI: Combination treatments in Psoriatic Arthritis
Despite the advances in the treatment of PsA with biologic (bDMARD) and targeted synthetic (tsDMARD), less than half of patients with this condition achieved remission or low disease activity. Combination DMARD treatment is often used in order to achieve remission or minimal disease activity. The standard practice is to use a conventional synthetic (csDMARD) with a bDMARD. The use of the combination of bDMARD with a tsDMARD such as a JAKi or TYK2i is a new order in the treatment of PsA.

ICYMI: Evaluation of Bimekizumab in PsA
Bimekizumab (BKZ) is a monoclonal IgG1 antibody that selectively inhibits interleukin (IL)‑17A and F. There have been more updates on the 2 year data on BKZ at #ACR24, and this is a summary of four studies being presented this year at ACR24.

Predicting flares in rheumatic diseases with machine learning
Rheumatic diseases, such as axial spondyloarthritis (axSpA) and rheumatoid arthritis (RA), are marked by unpredictable disease flares that adversely impact quality of life and long-term outcomes.
