title: A follow-up study of 48 patients with Reiter's syndrome.
abstract: A follow-up study of 48 patients with Reiter's syndrome was carried out in an attempt to clarify the clinical course of the disease. The mean age at the onset of Reiter's syndrome was 27.1 years (range 15 to 52 years) and when seen at follow-up 32.5 years (range 19 to 58 years). The average time from the onset of the first attack of peripheral arthritis to the time of follow-up was six and a half years (range 0.5 to 27 years). Only three patients had diarrhea prior to the onset of Reiter's syndrome. At follow-up 22 per cent of the patients were asymptomatic, 24 per cent had recurrent minor symptoms, 24 per cent had recurrent moderate symptoms, and 30 per cent had recurrent major symptoms. However, even in the last group, all patients were in functional classes 1 or 2 between the flares of disease. No patients in the series were in functional class 3 or 4, and 30 per cent were in class 1.
