Long-term Entecavir Leads to Regression of Liver Fibrosis in Chronic Hepatitis B Patients

Chronic hepatitis B treatment using entecavir (Baraclude) for 1 year is good, but 3 years is better, according to an international study published in the September 2010 issue of Hepatology. Patients who received at least 3 years of cumulative entecavir therapy showed substantial histological improvement on liver biopsies and experienced regression of liver fibrosis or cirrhosis.

Flares during HBV Treatment Do Not Predict Response, May Cause Liver Failure

Developing hepatic flares, or sudden increases in liver enzymes or viral load, while undergoing nucleoside/nucleotide analog therapy for chronic hepatitis B did not increase the likelihood of sustained viral clearance and led to decompensated liver failure in some patients, researchers reported in the July 2011 Journal of Viral Hepatitis.

How Long Do Chronic Hepatitis B Patients Need to be Treated to Sustain HBeAg Seroconversion?

Longer treatment with antiviral agents such as lamivudine, and use of pegylated interferon for selected individuals, increases the likelihood of sustained hepatitis B "e" antigen (HBeAg) seroconversion and viral suppression in people with chronic hepatitis B, according to a set of recently published reports. Across the studies, younger age and longer duration of lamivudine therapy predicted sustained response. The data were not entirely consistent, however, indicating the need for further research in this area.

Adding Adefovir Works Better than Entecavir Monotherapy for Lamivudine-resistant Hepatitis B Patients

Addition of adefovir (Hepsera) to lamivudine (Epivir-HBV) proved to be a better "rescue therapy" strategy for patients with lamivudine-resistant hepatitis B virus (HBV) than switching to entecavir (Baraclude) monotherapy, according to a South Korean study published in the August 2010 Journal of Gastroenterology and Hepatology.
