The oral antiviral valacyclovir, which is 3 to 5 times more bioavailable than its parent compound acyclovir, is a good candidate for effective therapy to suppress recurrent herpes labialis lesions. The efficacy of oral valacyclovir in the suppression of herpes labialis has not previously been reported. Two identical, randomized, double-blind, parallel-group studies were conducted to evaluate th...

BACKGROUND DATA AND OBJECTIVE Herpes is a common infectious disease that is caused by human herpesviruses. Several treatments have been proposed, but none of them prevent reactivation of the virus. This article describes the use of photodynamic therapy (PDT) as a treatment for herpes lesions, and reports on four cases. MATERIALS AND METHODS PDT was used as an adjuvant therapy for the treatmen...

Incidence rates for varicella and herpes zoster were similar in patients with juvenile idiopathic arthritis receiving etanercept/methotrexate (n = 85, 184.9 patient-years [PY]) or methotrexate alone (n = 71, 199.4 PY); no complicated varicella or herpes zoster cases were reported; herpes labialis incidence was higher in patients receiving etanercept/methotrexate versus methotrexate alone (0.38 ...

Of 51 patients with herpes simplex labialis, 50 had detectable interferon (IFN) in samples of lesion vesicle fluid. The median titer of vesicle fluid IFN was 8,200 U. and the range of values was 400 to 63,600 U. The amount of vesicle fluid IFN was correlated with lesion age (r = 0.32, P = 0.024) and vesicle fluid virus titer (r = 0.59, P = 0.00004), but not with the clinical severity of the dis...

BACKGROUND Imiquimod is currently approved for the treatment of genital warts and has been shown to decrease recurrences of genital herpes in the guinea pig model of genital herpes. Therefore, we evaluated the safety and potential of topical imiquimod to decrease the rate of recurrence in humans with a history of recurrent herpes labialis. METHODS Forty-seven subjects with recurrent herpes la...

In a general population survey in the United States, the prevalence of antiviral-agent-resistant herpes simplex virus was very low among more than 1,000 isolates from individuals with an episode of recurrent herpes labialis not treated with topical antiviral agents. Two isolates had borderline resistance to acyclovir (0.2%), and all were susceptible to penciclovir.
