Reiter's syndrome: chronicity of symptoms and employment

To assess the chronicity of symptoms and long term prospects for employment in patients with Reiter's syndrome, a follow-up study of 111 patients was performed. Ninety-eight patients were available for follow-up; these had a mean disease duration of 7.9 years (range two months to 39 years). At follow-up, 55 patients had symptomatic joints and 26 objective evidence of synovitis, but only seven had chronic joint deformity. Seven patients fulfilled criteria for ankylosing spondylitis. Ninety-three patients were in functional class I or II, 86 patients were working, 26 had changed employment, and 11 were unemployed because of the disease. No prognostic features of value were identified. The tissue antigen HLA B27 was associated significantly with anterior uveitis and radiological sacroiliitis.
