[Fiessinger-Leroy-Reiter disease seen in a rheumatology unit. Apropos of 71 cases].

71 cases of Reiter's disease have been observed since 1972. After a study of the clinical characteristics of these cases, we report the results of 3 laboratory examinations which, grouped together, facilitate the diagnosis of the complete forms, but, above all, of the incomplete and synovial forms. The search for chlamydia cell inclusions was positive in 80% of cases where carried out. The lymphocyte transformation test with the chlamydia antigen was positive in 72% of cases. The search for HLA B27 was positive in 78% of cases.
