Telbivudine, an FDA pregnancy category B drug, has been found to reduce hepatitis B virus (HBV) perinatal transmission with no safety concerns in infants aged up to 1 year. This study evaluated the long-term efficacy and safety of telbivudine in 214 infants born to 210 pregnant women with chronic hepatitis B infection who were treated with telbivudine during pregnancy (weeks 20-32 of gestation). The infants were followed for up to 5 years after birth. The efficacy endpoint was the rate of perinatal transmission, which was established by HBsAg and HBV DNA levels at 7 and 12 months...

BACKGROUND AND OBJECTIVE: Nucleos(t)ide analogue (NA) monotherapies are typically used as the primary treatment for chronic hepatitis B (CHB) patients, including lamivudine (LAM), telbivudine (TBV), adefovir (ADV), entecavir (ETV) and tenofovir (TDF). For high-resistance NAs (LAM, TBV, ADV), they can generate excellent clinical outcomes by using response-guided therapy; however, their pharmacoeconomic profiles remain unclear in China. We aimed to evaluate the cost effectiveness between response-guided therapies and monotherapies of NAs for Chinese hepatitis B e-antigen (HBeAg)-positive and -negative CHB patients...

Inhibition of viral replication is the most important goal in patients with Hepatitis B virus chronic infection (CHB). Currently, five oral nucleo(t)side analogues (NAs), including Lamivudine, Adefovir, Telbivudine, Entecavir and Tenofovir, have been approved for treatment. The widespread use of NAs has also been linked with a progressive growth of unlikely anomaly attributable to mitochondrial dysfunctions, not previously recognized. Here we explore the hypothesis that NAs may cause persistent epigenetic changes during prolonged NAs therapy in CHB patients...

BACKGROUND: Nucleos(t)ide analogs (NUCs) are the standard of care for chronic hepatitis B (CHB). The present analysis aimed to determine the cost effectiveness of NUCs in Chinese healthcare settings. METHODS: A Markov model was used to simulate two therapeutic strategies for a hypothetical patient cohort diagnosed with hepatitis B e antigen-positive CHB, unwilling or unable to receive interferon therapy, and about to start treatment with any NUC. The first strategy included NUC monotherapy without sequencing (telbivudine [LDT], entecavir [ETV], tenofovir [TDF], lamivudine [LAM], adefovir dipivoxil [ADV], and combination therapies of either LDT and ADV or LDT and TDF, followed by best supportive care [BSC])...

Persistent hepatitis B virus (HBV) infections affect about 240 million patients worldwide that are at risk of developing liver cirrhosis or hepatocellular carcinoma. HBV is a small, partially double stranded DNA virus with four overlapping genes and a unique life cycle, which involves the generation of an RNA template for replication via reverse transcription. Mutations occur frequently during chronic infection, and particular selection pressures select distinct mutants. Nucleoside and nucleotide analogues like lamivudine (LMV), entecavir (ETV), telbivudine (LdT), adefovir dipivoxil (ADV) and tenofovir (TDF) are used to achieve long-term suppression of viral replication...

Telbivudine, a thymidine nucleoside analog, is a common therapeutic option for chronic hepatitis B infection. While raised serum creatine kinase is common, myopathy associated with telbivudine is rare. Reports on its myopathological features are few and immunohistochemical analyses of inflammatory cell infiltrates have not been previously described. We describe the clinical, myopathological and immunohistochemical features of four patients who developed myopathy after telbivudine therapy for chronic hepatitis B infection...

A significant proportion of patients with chronic Hepatitis B infection require antiviral therapy during their life time. The Antiviral therapy with lamivudine or adefovir or telbivudine has shown to be a major risk factor for selection of resistance. Eighty percent of patients showed a development of lamivudine-resistant strains after five years of treatment with lamivudine alone. Adefovir and telbivudine inhibit HBV with very high efficacy and have moderate incidences of drug resistance. Entecavir and tenofovir have been shown to have a higher barrier to resistance with rates of less than 1...

Hepatitis B virus (HBV) infection is one of the most serious health problems worldwide with a high risk for cirrhosis and liver cancer. Several antiviral agents have been approved for the treatment of chronic hepatitis (CHB), leading to a rapid reduction in HBV DNA and normalization of serum alanine aminotransferase (ALT) levels. Telbivudine, a potent inhibitor of HBV replication, has been shown to be well tolerated. Due to the emergence of drug resistance, optimization strategies for telbivudine therapy have been shown to improve patient responses...
