Cytomegalovirus (CMV) infection and disease, with its extensive direct and indirect consequences, adds considerably to the cost of patient management in both solid organ and bone marrow transplantation. Antiviral prophylaxis for CMV infection can offer cost advantages over preemptive therapy and "wait-and-treat" approaches. Valacyclovir has demonstrated efficacy for CMV prophylaxis in renal, he...

OBJECTIVE Herpes simplex virus type 2 (HSV-2) suppression has been shown to reduce HIV-1 disease progression in non-pregnant women and men, but effects on pregnant and postpartum women have not been described. METHODS We analyzed data from a cohort of Kenyan women participating in a randomized clinical trial of HSV-2 suppression. Pregnant HIV-1-seropositive, HSV-2-seropositive women who were ...

A simple and reproducible spectrophotometric method has been developed for the determination of valacyclovir in bulk and pharmaceutical dosage forms. The proposed method was based on the formation of chloroform extractable complex of valacyclovir with wool fast blue. The absorbance of the extractable ion pair complex is measured at the wavelength of maximum absorbance 585 nm against the reagent...

OBJECTIVE To evaluate the effect of treatment with the antiherpes drug valacyclovir on MRI-evident lesions in patients with relapsing-remitting MS in a phase 2, randomized, double-blind, placebo-controlled study. BACKGROUND It has been postulated from virologic studies that herpesvirus infection could play a role in the progression of MS. METHODS Patients were eligible for the study if they...

BACKGROUND Standard-dose HSV-2 suppressive therapy (acyclovir 400 mg twice daily) reduces plasma HIV-1 levels by 0.25-0.50 log(10) copies/mL. It is not known if higher doses might further suppress HIV-1 levels. METHODS We enrolled 32 HIV-1/HSV-2 dually infected Kenyan individuals who were not on antiretroviral therapy (ART) into a randomized, crossover trial of 2 dosing regimens of HSV-2 supp...

Background: Acyclovir, a specific and selective inhibitor of replication of herpesviridae family, has well documented efficacy for speedy rash healing and decreasing pain of herpes zoster. Limited oral bioavailability of acyclovir requires frequent dosing. Valacyclovir is rapidly and almost completely converted to acyclovir in vivo and gives three to fivefold increase in acyclovir bioavailabili...

Epstein-Barr virus (EBV) establishes a latent infection in B cells in the blood, and the latent EBV load in healthy individuals is generally stable over time, maintaining a "set point." It is unknown if the EBV load changes after long-term antiviral therapy in healthy individuals. We treated volunteers with either valacyclovir (valaciclovir) or no antiviral therapy for 1 year and measured the a...

Response of EBV infection to valacyclovir in HIV infected children has not been reported earlier. An 8 years old HIV infected girl with undetectable viral load and normal CD4 count on regular antiretroviral therapy presented with persistent fever, lymphadenopathy and pancytopenia due to Epstein Barr virus (EBV). The child responded to valacyclovir.

OBJECTIVE To study whether prednisolone reduces sequelae in Bell's palsy. DESIGN Prospective, randomized, double-blind, placebo-controlled, multicenter trial with 12 months of follow-up. SETTING Seventeen referral centers. PATIENTS In all, 829 patients aged 18 to 75 years. INTERVENTIONS Randomization within 72 hours in a factorial fashion to placebo plus placebo (n = 206); prednisolone,...

There are 3: valacyclovir, acyclovir, and topical penciclovir. valacyclovir, 2 g twice in 1 day taken during the prodromal stage of herpes labialis, reduces the episode duration and time to healing. Acyclovir, 400 mg, taken 5 times a day for 5 days, decreases the pain duration and healing time to loss of crust (strength of recommendation [sor]: a, based on randomized controlled trials [rCTs]). ...
