Characteristics of long-term asymptomatic infection with human immunodeficiency virus type 1 in men with normal and...

From a cohort study of homosexual men in Amsterdam, 61 human immunodeficiency virus (HIV)-infected men who had remained asymptomatic for at least 7 years were identified. In a nested case control study, these men were compared with 142 men who progressed symptomatic HIV infection (CDC class IV) within 7 years, regarding laboratory markers, sexual behavior, psychologic coping, and drug use. Of the 61 long-term asymptomatic men, 13 had a CD4+ cell count > or = 500/mm3 after 7 years; in 2 of these 13, the CD4+ cell count had not declined during follow-up. Independent of CD4+ cell count, long-term asymptomatic HIV-1 infection was characterized by stable T cell reactivity after stimulation with monoclonal CD3 antibodies, seropositivity for antibodies to HIV core proteins, and the absence of hepatitis B markers. No association with markers of high-risk sex or the recreational use of drugs was found. Long-term asymptomatic men had a slightly lower score regarding the coping behavior active problem-solving; no other associations with coping behaviors were found.
