[Epidemiological study of Reiter's syndrome in a health service area].

: A higher incidence of Reiter's Syndrome (RS) is observed among young white men. We have conducted an epidemiological study of RS cases from our current health area and diagnosed in our hospital between 1975 and 1989. Twenty-four patients were included in this study, with a relation between men and women of 12:1 and an average age of 33.4 years. The annual incidence rate was 2.66 for men and 0.65 for women per 100,000 population during the study period. We have observed a tendency towards younger ages in the recent years and we have detected the presence of the HLA B-27 marker in 79% of patients.
