An acute remission of Reiter's syndrome in male patients treated with bromocriptine.

We describe 4 male patients with Reiter's syndrome treated with bromocriptine. All 4 had infectious gastroenteritis and chronic Reiter's syndrome with arthritis and enthesopathy that persisted despite treatment in 3 with antiinflammatory drugs and 1 with sulfasalazine for long periods. In all patients treatment was cancelled 8 days before bromocriptine treatment. In 2 patients a dramatic improvement was observed 24 h after 2.5 mg/day of bromocriptine. Two patients improved after 4 days of bromocriptine treatment (5 mg/day). All 4 patients remained asymptomatic for at least 4 months of bromocriptine treatment. Bromocriptine may be useful for treating male patients with Reiter's syndrome.
