Liver disease among homosexual males.

5% of 2612 homosexual males attending genitourinary clinics were found to be hepatitis-B surface-antigen (HBsAg) positive. Liver biopsy was done in 25 who had abnormal liver-function tests but no symptoms or signs of liver disease, and 14 (56%) of these proved to have chronic active hepatitis or active cirrhosis. Neither the liver-function tests nor the viral markers in serum reflected the severity of the liver disease. 38% of a group of 118 HBsAg positive patients were HBeAg positive, and sexual contacts of these individuals may be at serious risk of infection.
