Neonatal herpes simplex virus (HSV) infection produces severe disease with unacceptable morbidity and mortality with current antiviral therapies. The effect of therapy with passive anti-HSV antibody and acyclovir was evaluated using a guinea pig model of neonatal HSV. Newborn animals were inoculated intranasally and treated with acyclovir (60 mg/kg/day) or antibody (or both), beginning on days ...

The effect of intravenous acyclovir (at a dosage of 30 mg/kg per day for five days) on uncomplicated herpes zoster was investigated in 51 patients in a double-blind study. Although existing herpes zoster lesions tended to heal more rapidly and new lesions ceased to appear somewhat earlier in the acyclovir group, these differences were not statistically significant. During treatment, patients on...

Acyclovir, guanine, and impurity A have been baseline separated with isocratic conditions at pH=3.0 and run time under 15 min by employing a SB-CN column from Agilent (150 mm x 4.6mm and 3.5 microm). Moreover, when run time was increased to 40 min six impurities (guanine, impurities A, F, G, Vir 3/4 and N(7)) plus acyclovir were separated in the same conditions. The mobile phase consisted of bu...

Sera from patients with first episode primary genital herpes infections who were treated with the antiviral drug acyclovir were studied to determine the effect of therapy on the immune response to herpes simplex virus (HSV) glycoproteins and polypeptides. 63 patients were evaluated, 35 patients received acyclovir: 11 intravenously, 12 orally, and 12 topically, while 28 received placebo. Topical...

mean concentrations (± standard deviations) at the end of infusion as measured by radioimmunoassay were 4.52 ± 0.31, 8.28 ± 2.61, 14.6 ± 2.30, and 22.7 ± 10.4 pg/ml, respectively. Drug elimination during and after the infusion of acyclovir was well described by a two-compartment open model. The mean terminal plasma half-life for each of the groups was 2.85, 2.80, 3.30, and 2.38 h, respectively....

The purpose of this study was to describe a presumed case of Epstein-Barr virus (EBV)-associated retinal vasculitis in a 42-year-old female with sudden unilateral vision loss and successful treatment with acyclovir therapy. Diagnostic vitreous biopsy of the right eye was performed to test for EBV and other known infectious causes of retinitis and evaluate vitreous cells and serological testing....

Sixty women patients experiencing a first attack of genital herpes were randomly treated with either oral acyclovir for 42 days or oral acyclovir for five days followed by placebo for 37 days. The median time to the first recurrence in patients receiving acyclovir for 42 days was 66.5 days compared with 24 days in those who received acyclovir for only five days (p less than 0.0001). This signif...

BACKGROUND Eczema herpeticum is an uncommon manifestation of an infection with herpes simplex virus (HSV). The disease is primarily seen in patients with histories of atopic eczema. Eczema herpeticum may be a life-threatening illness, but the mortality is felt to be <10% with modern antiviral and antibacterial agents. The use of acyclovir for other viral infections secondary to herpesvirus in p...

A 75-year-old woman developed a moderately severe rash about a week and a half after the start of bortezomib (Btb)-based chemotherapy for IgG lambda multiple myeloma; at the time, she was also receiving acyclovir as antiviral prophylaxis in addition to herpes zoster (HZ) vaccination. HZ reactivation rate is high in Btb recipients; therefore, the timing of antiviral prevention is critical in rel...
