Advanced glycation end products (AGEs) are harmful molecules that accumulate in the body over time and are known to promote inflammation and oxidative stress. Increased AGE burden has been implicated in several chronic diseases; however, its role in rheumatic diseases has not been fully clarified.\n\nThis observational, cross-sectional study aims to evaluate the accumulation of AGEs in patients with various rheumatic diseases compared with healthy individuals. AGE levels will be assessed non-invasively using skin autofluorescence measurements.\n\nBy comparing AGE burden between patients and healthy controls, this study seeks to improve understanding of the potential role of AGEs in the pathophysiology of rheumatic diseases and to explore their usefulness as a non-invasive biomarker in clinical practice.",[42,43,44,45,46,47,48],"Rheumatoid Arthritis (RA","Ankylosing Spondylitis","Psoriatic Arthritis","Reactive Arthritis (ReA)","Crystal Arthropathies","Connective Tissue Diseases","Familial Mediterranean Fever (FMF )","NOT_YET_RECRUITING","2026-01-08",{"date":52,"type":53},"2026-01-09","ACTUAL",{"date":55,"type":38},"2026-01-15",{"date":57,"type":38},"2027-04-15",{"name":5,"class":6}]
