Abstract

Abstract Background.Kaposi's sarcoma (KS) associated with human immunodeficiency virus type 1 (HIV-1) is the most common malignancy in patients with AIDS. It has been most commonly reported in white homosexual men, though a few cases have been reported in blacks. Methods.We conducted a retrospective analysis of all HIV-1 seropositive patients with biopsy-proven KS seen at Howard University Hospital between February 1985 and June 1995. Results.Of the 73 patients identified, 66 (90%), 4 were white, 2 were Hispanic, and 1 was of unidentified race. The median age was 32 years. Forty-eight (66%) were homosexual or bisexual men, and 10 (14%) were homosexual or bisexual with a history of intravenous drug use (IDU). A history of IDU or blood transfusion was the only risk factor in 7 (9%) and 2 (3%), respectively. The other 6 (8)% were heterosexual. The median survival was 2.2 years. A CD4 count <200 and the presence of an opportunistic infection were associated with shortened survival. Conclusions.The predominant risk factor for HIV-1–associated KS was homosexual or bisexual activity. Only a few women with KS were identified, and they also reported sexual transmission from male bisexuals and/or drug users. Poor survival was associated with CD4 <200, stage III and IV KS at presentation, and opportunistic infections.
