AB Cytomegalovirus (CMV) isolates from 234 asymptomatic human
immunodeficiency type 1 (HIV-1)-positive men were analyzed for molecular
relatedness using junctional hybridization. Of isolates shed
simultaneously at two or more body sites, 36% from 22 men were
different. Of 180 isolates collected from 67 men over 15 months,
different strains were isolated serially from 27 men (40%), most from
semen. After follow-up of 58 months (mean), the relative hazard of HIV
infection progressing to AIDS was 1.8 (95% confidence interval [CI],
0.9-3.7) for men shedding the same strain of CMV and 3.0 (95% CI,
1.4-6.1) for men shedding different strains compared with men not
shedding CMV in semen. The prevalence of CMV-specific IgM was higher in
men shedding different versus same CMV strains (32% vs. 18%; P = .244).
Thus, presence of multiple CMV strains in HIV-1-positive homosexual men
is associated with progression to AIDS, possibly via activation of
HIV-1-infected CD4 cells.
