Abstract

Background: Bacterial vaginosis (BV) has been associated with increased HIV cervicovaginal shedding. We hypothesized that this might relate to BV-associated increases in mucosal activated CD4+ T cells, which could enhance local HIV replication. Methods: Vaginal flora, cytokine/chemokine levels, and mucosal immune cell populations collected by cervical cytobrush were analyzed in 15 HIV-infected Kenyan female sex workers, before and after BV therapy with oral metronidazole. Results: Therapy reduced the Nugent score in all but 1 participant, and BV elimination was associated with reduced genital levels of interleukin 1β(IL1β), interleukin 8 (IL-8), and Regulated Upon Activation Normal T-cell Expressed and Secreted (RANTES). In addition, BV elimination reduced the total number of cervical CD4+ T cells, including those expressing the HIV coreceptor CCR5 and the activation marker CD69. Conclusions: BV induces significant and reversible alterations in cervical immune cell populations and local inflammatory cytokines that would be expected to enhance local HIV replication.
