, was previously reported to partially restore replication fitness as well as to augment drug resistance in vitro. Here we report the functional characterization of a third polymerase mutation (rtV173L) associated with resistance to lamivudine and famciclovir. rtV173L was observed at baseline in 9 to 22% of patients who entered clinical trials of adefovir dipivoxil for the treatment of lamivudine-resistant HBV. In these patients, rtV173L was invariably found as a third mutation in conjunction with rtL180M

383. HBsAg Seroclearance in Chinese Patients Receiving Lamivudine Therapy for Chronic Hepatitis B Virus Infection (PubMed)
HBsAg Seroclearance in Chinese Patients Receiving Lamivudine Therapy for Chronic Hepatitis B Virus Infection We report two Chinese patients in whom lamivudine treatment resulted in HBsAg seroclearance. One patient received lamivudine, and another patient received 12-week famciclovir treatment followed by lamivudine. Lamivudine was maintained after HBeAg seroconversion. These two patients lost HBsAg at 24 and 27 months (ages, 23 and 19.3 years, respectively) and developed measurable titer

386. Valacyclovir+Temovate Gel for the Treatment of Herpes Labialis
study has been proposed because it has become clear there are marked limitations to the benefit of antiviral therapy in herpes labialis. Recently, a pilot trial of the combination of famciclovir and topical 0.05% fluocinonide vs famciclovir alone showed that the addition of corticosteroids to the antiviral drug treatment caused a marked and statistically significant reduction in lesion size and a trend to more aborted lesions. This study is designed as a randomized, placebo-controlled, , patient
