Definition (MSHCZE) Chorobný stav řazený k reaktivním artritidám (spondylartritidám) charakterizovaný nehnisavým zánětem kloubů při současném zánětlivém postižení močové trubice (uretritida), oční spojivky (konjunktivitida), následující obv. po střevním zánětu, klasicky po dysenterii. Může být při venericky získané chlamydiové infekci močových cest. Často je přítomen histokompatibilní antigen HLA-B27. Klasická triáda je spíše vzácná. (cit. Velký lékařský slovník online, 2013 http://lekarske.slovniky.cz/ )
Definition (NCI) A rare, reactive inflammatory disorder seen following bacterial infection. It predominantly affects males aged 20-40. Individuals with HLA-B27 antigen are estimated to have a 50 % increased risk. The disorder is characterized by arthritis, conjunctivitis, uveitis, iritis and ulceration of the oral cavity, genitals and volar surfaces of the hands and feet. The clinical course is self-limited with resolution of clinical disease usually within six months of onset.
Definition (CSP) triad of nongonococcal urethritis followed by conjunctivitis and arthritis.
Definition (MSH) Historically characterized by a triad of inflammation involving the eye (CONJUNCTIVITIS), the bone (POST-INFECTIOUS ARTHRITIS), and the urethra (URETHRITIS), it is now thought to be nearly synonymous with reactive arthritis.

Ontology: Arthritis, Reactive (C0085435)

Definition (MSH) An aseptic, inflammatory arthritis developing secondary to a primary extra-articular infection, most typically of the GASTROINTESTINAL TRACT or UROGENITAL SYSTEM. The initiating trigger pathogens are usually SHIGELLA; SALMONELLA; YERSINIA; CAMPYLOBACTER; or CHLAMYDIA TRACHOMATIS. Reactive arthritis is strongly associated with HLA-B27 ANTIGEN.
