Abstract

Hepatitis B surface antigenemia (HBsAg) is the hallmark of HBV infection. Serum levels of HBsAg appear to reflect the degree of immune control over the virus: lower levels signify a higher level of immune control. One year of peginterferon (PEG-IFN) therapy results in a decline of HBsAg in serum that is sustained off-treatment. Patients who achieve a sustained virological response to PEG-IFN have more pronounced on-treatment HBsAg decline. HBsAg levels during therapy can be used to predict the chance of treatment success. Among HBeAg-positive patients, the probability of response is extremely low in patients with HBsAg levels >20,000 IU/mL at week 24 of treatment and therapy discontinuation is indicated. Similarly, therapy cessation is indicated in HBeAg-negative patients without HBsAg decline at week 12 if HBV DNA has not been reduced by at least 2 log IU/mL.

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
