Acyclovir (ACV), a highly specific anti-herpetic drug, acts as a DNA chain terminator for several human herpesviruses (HHVs), including HHV-2 (HSV-2), a common human immunodeficiency virus (HIV)-1 co-pathogen. Several trials demonstrated that HSV-2 suppressive therapy using ACV or its prodrug valacyclovir (val ACV) reduced plasma HIV-1 viral load (VL) in HIV-1/HSV-2 coinfected persons, and this was proposed to be due to a decrease in generalized immune activation. Recently, however, we found that ACV directly suppresses HIV-1 Eighteen HIV-1 infected HSV-2-seronegative individuals were randomly assigned in a double blind placebo-controlled, crossover trial. Eligible participants had CD4 cell counts of ≥500 cells/µL and were not taking antiretroviral therapy. Subjects in group A received 12 weeks of val ACV 500 mg given twice daily by mouth followed by 2 weeks of a no treatment washout and then 12 weeks of placebo; subjects in group B received 12 weeks of placebo followed by 2 weeks of no treatment washout and then 12 weeks of val ACV 500 mg twice daily. These data indicate that the effects of val ACV on HIV-1 replication are not related to the suppression of HSV-2-mediated inflammation and are consistent with a direct effect of ACV on HIV-1 replication. Acyclovir (ACV) was the first safe, potent, and specific antiviral nucleoside analogue to be approved for clinical use .

Listing a study does not mean it has been evaluated by the U. Can herpes simplex virus type 2 suppression slow HIV disease progression: a study protocol for the VALacyclovir In Delaying Antiretroviral Treatment Entry (VALIDATE) trial. This study is a multicentre, randomized, placebo-controlled, fully blinded, clinical trial of twice daily oral valacyclovir 500mg versus placebo with the goal of delaying the need for initiating HAART among HIV infected individuals who neither use nor require HAART, and who have not used chronic suppressive anti-HSV therapy for at least the 6 months prior to study initiation.

Genetic testing of HLA-B*5701 and HLA-B*5703 status, and future genetic markers related to HIV disease progression and the impact of herpes and valacyclovir. It is a pro-drug of aciclovir (Zovirax), meaning that it is broken down into aciclovir within the body. Valaciclovir produces higher blood levels of the active drug than is possible using the conventional tablet formulation of aciclovir. Valaciclovir was formerly known by the codename BW256U87, and is known by the generic name netivudine. In February 1995, an international study testing valaciclovir and high doses of aciclovir as preventive treatment for cytomegalovirus was stopped seven months early because participants who received valaciclovir were more likely to develop side-effects and had a significantly higher death rate, possibly due to higher levels of active drug. However, since valaciclovir was taken for a shorter period than aciclovir, there was no difference between the two arms once the full follow-up period of the study was completed. However, valaciclovir is effective in preventing cytomegalovirus in patients with HIV. A study of 310 patients with advanced HIV disease found that the drug lowered cytomegalovirus levels in the blood, delaying the onset of disease to a greater extent than aciclovir. In HIV-positive people, a dose of 1000mg twice daily was shown to be comparable to 200mg aciclovir five times daily in treating a single episode of genital herpes, while 500mg twice daily was superior to placebo in preventing or delaying recurrences. Valaciclovir appears to be linked to a potentially fatal type of bleeding in the kidneys, known as haemolytic uraemic syndrome.
