Herpes simplex virus type 2 (HSV-2) infection is associated with a 3-fold increase in the risk of human immunodeficiency virus (HIV) acquisition, perhaps through alterations in mucosal HIV-susceptible target cells. We performed a clinical trial to assess the impact of herpes therapy on cervical immunology in HSV-2-infected, HIV-uninfected women from Africa or the Caribbean who were living in Toronto, Canada. Thirty participants received 1 g of valacyclovir orally each day for 2 months in a randomized double-blind, placebo-controlled, crossover trial. Valacyclovir did not reduce the number of cervical CD4(+) T cells, the number of dendritic cells, or the expression of proinflammatory cytokines and tended to increase the expression of the HIV coreceptor CCR5 and the activation marker CD69. Short-term valacyclovir therapy did not reverse HSV-2-associated alterations in genital immunology. Clinical Trials Registration. NCT00946556.
