  Purpose
The study proposed that both clinical and subclinical HSV reactivation is associated with increased HIV shedding from mucosal surfaces, which may increase the infectiousness of HIV-1/HSV-2 coinfected persons. To test this hypothesis, we will control HSV reactivation with acyclovir, a safe medication that is proven to reduce HSV shedding, and measure HIV levels in blood, genital, and pharyngeal secretions. The study hypothesizes that acyclovir will reduce HIV shedding from mucosal surfaces of HIV-1/HSV-2 coinfected individuals.

Primary Outcome Measures:
  • HSV and HIV viral shedding [ Time Frame: 18 weeks ]

Secondary Outcome Measures:
  • HSV suppression and HIV shedding [ Time Frame: 18 weeks ]

Estimated Enrollment: 40
Study Start Date: March 2005
Study Completion Date: April 2007
Arms Assigned Interventions
1
Acyclovir 800 mg twice daily for 8 weeks, two week washout, 8 weeks placebo
Drug: Acyclovir
Acyclovir 800 mg twice daily or placebo
2
8 weeks placebo, 2 week washout, 8 weeks 800 mg acyclovir twice daily
Drug: Acyclovir
Acyclovir 800 mg twice daily or placebo

Detailed Description:

The main objective is to assess the reduction in genital HIV-1 shedding associated with daily acyclovir for suppression of HSV-2 reactivation.

All patients will be treated with the usual antibiotic treatment for any sexually transmitted infections that are diagnosed during the study. In addition, half will receive acyclovir for 8 weeks , whilst the other half will receive a placebo for 8 weeks. The study medication will reverse in the second 8 weeks of the study. The patients will attend the clinic 3 times per week during the first and the last 8 weeks of the study and once every week during the washout period in the middle of the study - for a total of 18 weeks per participant. At each visit genital and oral samples will be collected. A blood sample will also be collected. For women participants, pregnancy test will be performed. The clinic will provide both pre- and post-HIV test counseling.
