Reiter's disease: modern concepts.

Reiter's disease (RD) is a reactive arthritis syndrome in which arthritis, conjunctivitis, dermatitis, and urethritis are the main features. It may be an acute and self-limited disease or it may cause severe debilitation. It generally follows an infectious episode, such as Shigella dysentery or nonspecific urethritis. Recent evidence has shown that patients in whom RD develops have a genetic disposition since the presence of HLA-B27 correlates highly with RD. Therapy of RD involves supportive care.
