BACKGROUND In this study, we aimed to identify baseline predictors of response in chronic hepatitis B patients treated with a combination of pegylated interferon (PEG-IFN)-α2a and adefovir. METHODS We treated 92 chronic hepatitis B patients (44 hepatitis B e antigen [HBeAg]-positive and 48 HBeAg-negative) with HBV DNA > 100,000 copies/ml (> 17,182 IU/ml) with PEG-IFN and adefovir for 48 weeks...
An isoleucine-to-valine change at position 233 (rtI233V) of hepatitis B virus (HBV) polymerase was recently reported to cause decreased in vitro susceptibility to, and treatment failure of, adefovir dipivoxil (ADV). To further evaluate these findings, we screened our ADV clinical-study sequence database of 853 patients and identified 4 who, at baseline, had HBV with this mutation. All 4 patient...
Chronic hepatitis B is a major global health problem. Fortunately there are currently a number of agents licensed in most countries to treat chronic hepatitis B, including the oral nucleos(t)ide agents lamivudine, adefovir, entecavir, telbivudine, and tenofovir, and the immune modulators interferon alfa-2b and peginterferon alfa-2a. Large clinical trials have shown potent suppression of viral r...
BACKGROUND AND AIMS Chronic hepatitis B (CHB) and its sequelae are major health problems in Taiwan. The purpose of the present study was the economic evaluation of short-duration treatments of CHB and longer duration antiviral treatment for up to 5 years. METHODS Ten-health state CHB disease progression Markov models were used for hepatitis B e antigen (HBeAg)-positive and HBeAg-negative CHB ...
Fibrosing cholestatic hepatitis (FCH) is a severe clinical and histological variant of hepatitis B virus (HBV) infection seen most commonly in the HBV infected allograft after liver transplantation. Without treatment, FCH is fatal, rapidly and universally. Remission has been reported with lamivudine but is associated with evolving resistance to lamivudine. Adefovir dipivoxil has recently been r...
This study compared antiretroviral activity among 6 "salvage" therapy regimens. The study was a prospective, randomized, 2x3 factorial, multicenter study of the AIDS Clinical Trials Group. The study enrolled 277 human immunodeficiency virus (HIV)-infected patients naive to nonnucleoside analogues who had taken indinavir >6 months. The patients had 2000-200,000 HIV RNA copies/mL. Patients receiv...
During the past decade, major breakthroughs have been achieved in treatment of chronic hepatitis B. Currently, three therapeutic agents are approved for chronic hepatitis B: interferon-alpha, lamivudine and adefovir dipivoxil. In patients with HBeAgpositive chronic hepatitis B, all of these drugs achieve HBeAg loss (24-33%) and anti-HBe seroconversion (12-30%) rates that are superior to those o...
Alkoxyalkyl esters of acyclic nucleoside phosphonates have previously been shown to have increased antiviral activity when they are administered orally in animal models of viral diseases, including lethal infections with vaccinia virus, cowpox virus, ectromelia virus, murine cytomegalovirus, and adenovirus. 9-(S)-(3-Hydroxy-2-phosphonomethoxypropyl)adenine [(S)-HPMPA] was previously shown to ha...
