Reactive arthritis (ReA) is an inflammatory arthritis that arises after certain types of gastrointestinal or genitourinary infections. It belongs to the group of arthritidies known as the spondyloarthropathies (SpAs). The classic syndrome is a triad of symptoms, including the urethra, conjunctiva, and synovium; however, the majority of patients do not present with this classic triad. In general, there are two forms of ReA, postvenereal (Chlamydia trachomatis [Ct]) and postdysentery (Salmonella, Shigella, Campylobacter, and Yersinia), but several other bacteria have been implicated as potential causes.
