Rheumatology Bulgaria, Vol. 34, Issue 3 (2026) moves beyond the joint to explore rheumatic disease as a truly systemic process. The issue spans structural damage in rheumatoid arthritis, the evolving management of RA-associated interstitial lung disease, cardiovascular pathways in psoriatic arthritis, urate deposition in the heart, emerging synovial-fluid biomarkers, and some of the most challenging diagnostic boundaries within the spondyloarthritis spectrum.
