Rapid progression of HIV-1 infection to AIDS.

Homosexually acquired human immunodeficiency virus type 1 infection is usually slowly progressive, and reports of its rapid progression to acquired immunodeficiency syndrome are rare. We present a case of acute human immunodeficiency virus type 1 and cytomegalovirus coinfection that progressed to acquired immunodeficiency syndrome and death in 7 months. The factors that determine the clinical outcome of human immunodeficiency virus type 1 infection are poorly defined; however, coinfection with other agents, such as cytomegalovirus, may influence its natural history.
