AASLD 2014: Pegylated Interferon + Tenofovir Improves Odds of HBsAg Loss in Hepatitis B Patients

People with chronic hepatitis B virus (HBV) infection are more likely to experience favorable treatment response, as indicated by hepatitis B surface antigen (HBsAg) loss, if they add pegylated interferon to tenofovir -- although even then the cure rate falls short of 10%, researchers reported at the American Association for the Study of Liver Diseases (AASLD) Liver Meeting this week in Boston.

HBV Rebounds After Stopping Entecavir, Switching to Interferon May Help

Most hepatitis B "e" antigen (HBeAg) negative chronic hepatitis B patients relapsed after stopping treatment with the antiviral drug entecavir (Baraclude), according to a report in the May 15 online edition of Gut. A related study found that switching from entecavir to pegylated interferon increased the likelihood of HBeAg seroconversion and hepatitis B surface antigen(HBsAg) lossin HBeAg positive patients.

IDWeek 2014: Hepatitis B Relapse Is Common After Stopping Antiviral Therapy

Hepatitis B virus (HBV) rebounded in nearly 80% of people treated with fully or partially suppressive antiviral therapy using adefovir (Hepsera), entecavir (Baraclude), lamivudine (Epivir), or tenofovir (Viread), indicating that long-term therapy is usually needed to control the virus, researchers reported at IDWeek 2014 last month in Philadelphia.

No Tenofovir Resistance Seen In 2 Years of Hepatitis B Treatment

No cases of resistance to tenofovir (Viread) were detected among chronic hepatitis B patients with prior resistance to lamivudine (3TC or Epivir) through 96 weeks of treatment, according to a study described in the June 11 advance edition of Clinical Gastroenterology and Hepatology. Adding emtricitabine (Emtriva) did not improve effectiveness compared with tenofovir alone.
