[Incidence of HIV infections among the patients of the outpatient clinic of the Institute of Venereology].

The presence of anti-HIV antibodies was sought in 1061 patients (818 men and 243 women) with various sexually transmitted diseases; the group of men contained 29 homosexuals (3.5%) and 26 were bisexual (3.2%). Together these deviants accounted for 7.1% of the group. EIA test confirmed with the Western-blot test gave positive result in 11 patients, including 10 homosexual and bisexual men, that is in 18.2% of the subgroup of men with this deviation, and in 1 heterosexual man (0.13%). Over one-half of them had or had had syphilis, and in the subgroup of homosexuals the patients with syphilis amounted to 36%. The proportion of HIV infections in homosexuals, patients of outpatient clinics for sexually transmitted diseases, is much higher than in heterosexual patients in these clinics and homosexuals not treated in these clinics. Patients in outpatient clinics for sexually transmitted diseases are a high risk group for HIV infection (especially homosexuals with syphilis) and should be tested for the presence of anti-HIV antibodies.
