Hepatitis B antigen and antibody in a male homosexual population.

Sera from 600 male homosexual patients were tested for hepatitis B antigen (HBs Ag) and its antibody (HBs Ab). Thirty-one men (5-2%) were positive for HBs Ag. Testing for HBs Ab by immuno-osmoelectrophoresis 33 men (5-5%) were positive. However, sera of 85 patients negative for HBs Ab by routine methods were examined for HBs Ab by radioimmune assay. Thirty (35%) sera were found to be positive. No absolute correlation between the detection of HBs Ag, or previous history of hepatitis, jaundice, or current hepatitis was found. Similarly there was little correlation between presence of HBs Ab and this history. These observations suggest that the male homosexual population represents a pool of individuals within which the hepatitis B virus is readily transmitted, mainly as a subclinical infection although clinical hepatitis does occur in some patients. It is suggested that further work is necessary to determine whether the high antibody rate in male homosexuals is related more to sexual practice than to promiscuity.

Genital yeast infections.

Genital yeast infection was studied in 533 women seen in a department of venereology. Yeasts were recovered in culture from 138 patients (26% of the total). Candida albicans accounted for 112 (81%) of the isolates and Torulopsis glabrata for 22 (16%); other yeasts were uncommon. There was no evidence that the presence of yeasts was related to age. 32% of the women who were taking an oral contraceptive harboured yeasts, compared with 18% of those who were not.The symptoms and signs of the women with yeast infections were compared with those with vaginal trichomoniasis and those with no evidence of genital infection. It seems that a clinical diagnosis of vaginal mycosis cannot be made with accuracy and that positive identification of yeasts is necessary; for this, cultural methods are the most satisfactory.
