Genital HSV detection among HIV-1-infected pregnant women in labor.

Abstract

Objective. To compare genital HSV shedding among HIV-positive and HIV-negative women. Methods. Women with and without known HIV infection who delivered at the University of Washington Medical Center between 1989–1996 had HSV serologies done as part of clinical care. Genital swabs from HSV-2-seropositive women were evaluated by real-time quantitative HSV DNA PCR. Results. HSV-2 seroprevalence was 71% and 30% among 75 HIV-positive and 3051 HIV-negative women, respectively, (P < .001). HSV was detected at delivery in the genital tract of 30.8% of HIV-seropositive versus 9.5% of HIV-negative women (RR = 3.2, 95% CI 1.6 to 6.5, P = .001). The number of virion copies shed per mL was similar (log 3.54 for HIV positive versus 3.90 for HIV negative, P = .99). Conclusions. Our study demonstrated that HIV-, HSV-2-coinfected women are more likely to shed HSV at delivery.
