B-cell Clonality in HCV-Induced Patients Treated with Oral Direct-Acting Antiviral Agents.

Background: Hepatitis C virus (HCV) is a worldwide' health problem as Egypt has a very high prevalence (14.7%) that may affect the B-Lymphocytes, and in some cases leading to an expansion of monoclonal B-cell detected by immunoglobulin heavy chain (IgH) gene rearrangement. Therefore, we aimed to assess the occurrence of IgH gene rearrangement in Egyptian chronic HCV patients and studying the effect of oral direct-acting antiviral (DAAs) therapy on regression of the clonality markers.
