  Purpose

The purpose of the study is to determine how common herpes is among persons with HIV who do not know they have it and if valacyclovir reduces outbreaks of herpes, the amount of HIV in the blood, and the amount of HSV in bodily secretions.

Detailed Description:

Most people with herpes infections do not know they have the infection. HSV infections most often occur in areas in and around the mouth and genital tract. HSV Type 1 (HSV-1) usually causes "cold sores" or fever blisters and HSV Type 2 (HSV-2) usually causes lesions in the genital or rectal areas. However, HSV-1 can sometimes cause genital herpes and HSV-2 can cause oral lesions (acquired from oral-genital sex). Herpes Simplex is transmitted by contact with someone who is shedding virus in either the mouth or genital tract, usually by kissing or sexual intercourse. While contact with an active sore can cause transmission, so can contact with saliva or genital secretions that are infected, even when the person does not have an obvious sore. This is called asymptomatic shedding of HSV. Once acquired, the virus has the ability to remain inactive in the nervous system in the area of the mouth or genital region.

Persons with both HIV and HSV-2 often have shedding of both viruses. We know that persons with HSV-2 tend to have increased amounts of HIV in their blood as well. Recently, research studies have found that taking medicine daily to prevent asymptomatic HSV-2 shedding can reduce the amount of HIV found in the blood and in genital secretions. This study seeks to determine how common herpes is among persons with HIV who do not know they have it and if valacyclovir (FDA approved drug) reduces outbreaks of herpes, the amount of HIV in the blood, and the amount of HSV in bodily secretions.
