Association of human T lymphotropic virus type III antibodies with sexual and other behaviors in a cohort of homosexual men from Boston with and without generalized lymphadenopathy

Abstract

Forty asymptomatic homosexually active men seen at a Boston community health center and 39 men with generalized lymphadenopathy were interviewed and filled out detailed epidemiologic questionnaires. Twenty percent of the asymptomatic men and 92 percent of those with lymphadenopathy had antibodies to human T lymphotropic virus type III (HTLV-III). None of the men have subsequently had the acquired immune deficiency syndrome (AIDS). Seropositivity was associated with receptive anal intercourse and oral exposure to ejaculate, a history of hepatitis B, anal gonorrhea, or intestinal parasites, but no other sexually transmitted diseases, and did not correlate with the use of recreational drugs. More of the seropositive men had multiple partners from New York City. An association with seropositivity was less evident in relation to the numbers of partners from San Francisco or Los Angeles, since the whole cohort generally had fewer contacts with partners from these cities. The data suggest that educational programs among homosexual men attempting to decrease AIDS risk should focus on decreasing the number of partners, receptive anal intercourse, oral exposure to ejaculate and other intimate rectal contact, and sexual contact with men from areas of increased HTLV-III seroprevalence.
