It remains unclear whether hepatitis B virus (HBV) genotype has an influence on treatment response -- as is the case for hepatitis C virus (HCV) -- due to inconsistencies across
studies and failure to account for differences in race/ethnicity, according to a report in the March 2010 Journal of Hepatology.
It is well known that viral genotype has a major impact on response to interferon-based therapy for hepatitis C, but it is unclear whether this is also true for hepatitis B.
