The article in the Journal of Rheumatology discusses Radiographic Axial Spondyloarthritis (Ankylosing Spondylitis) commencing late in life. It highlights the rarity of disease onset at age 50 or older and compares the clinical presentation of late-onset AS to early-onset disease. The study found differences in manifestations such as peripheral arthritis, uveitis, and HLA-B27 frequency between the two groups, indicating the need for further research to understand prognosis and treatment response in late-onset AS.
