Psoriatic Arthritis News and Research

RSS

Like rheumatoid arthritis (RA), psoriatic arthritis is a chronic inflammatory disease of the joints and connective tissue. The disease causes joint pain and swelling that can lead to crippling along with inflamed and irritated scaly red patches of skin throughout the body. It is a progressive and debilitating disease and because there are no treatments specifically approved for psoriatic arthritis, doctors often use therapies approved for RA, including nonsteroidal anti-inflammatory drugs (NSAIDs) and disease modifying anti-rheumatic drugs (DMARDs). However, no DMARDs are currently approved for use in psoriatic arthritis. There are approximately 300,000 patients with psoriatic arthritis in the United States and the disease affects both men and women most commonly between the ages 30 and 50. Psoriatic arthritis patients are generally treated by rheumatologists and dermatologists.

EuroSpA study links country income to arthritis treatment outcomes

A study initiated by the European Spondyloarthritis Research Collaboration Network (EuroSpA) examined whether where patients with psoriatic arthritis (PsA) or axial spondyloarthritis (axSpA) live is associated with the severity of their disease, when they begin advanced treatment, and how long they continue that treatment.

Review finds vitamin D lacks disease-modifying effect in rheumatic diseases

A new review from the International Osteoporosis Foundation (IOF) Osteoimmunology Working Group, published in Osteoporosis International, provides a comprehensive evaluation of the role of vitamin D in inflammatory rheumatic diseases.

GLP-1 therapies linked to fewer complications in adults with both obesity and autoimmune disease

Among adults with both obesity and an autoimmune disease, those taking a glucagon-like peptide-receptor 1 agonist (GLP-1RA) medication had lower rates of emergency department visits and were less likely to experience serious cardiac events, such as stroke, pulmonary embolism or death when compared to similar adults who were not taking these medications, according to new research published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.

Natural peptide PEPITEM shows promise in reducing arthritic joint swelling

Scientists investigating the naturally occurring immunopeptide PEPITEM have shown reductions in arthritic joint swelling to a degree comparable to the current standard of care, and reduce the inflammatory changes that cause joint damage.

He needs an expensive drug. A copay card helped — until it didn’t.

Over the course of 2025, Jayant Mishra of Mission Viejo, California, progressively developed scaly, itchy red patches on his skin. Then came the pain and swelling in the joints of his hands, making it difficult to do his work at a bank.

New evidence-based points to consider and consensus definitions for people with psoriatic arthritis

Some people with psoriatic arthritis (PsA) may have disease that is difficult to manage (D2M) or does not respond to treatment. EULAR - The European Alliance of Associations for Rheumatology - has released new evidence-based points to consider and consensus definitions for these groups.

Low-calorie diets linked to higher psoriatic arthritis risk, genetic study suggests

This Mendelian randomization study found that low-calorie diets may slightly increase the risk of psoriatic arthritis, while vegetarian and gluten-free diets showed no causal links to psoriasis, acne, or atopic dermatitis. The findings challenge assumptions about universally beneficial dietary patterns and highlight the need for cautious interpretation of dietary interventions in inflammatory skin disease.

Early intensive therapy shows promise in psoriatic arthritis patients with poor prognostic factors

Is there a benefit to early bDMARD? In psoriatic arthritis (PsA) EULAR - The European Alliance of Associations for Rheumatology - recommends a treat-to-target approach, and suggests more intensive therapy for people with poor prognostic factors, depending on the disease presentation.
