The US Food and Drug Administration (FDA) on Tuesday warned of serious risks for some patients who have been infected with the hepatitis B virus (HBV) and are being treated with certain direct-acting antiviral (DAA) medicines for hepatitis C virus (HCV).
FDA identified 24 cases of HBV reactivation reported to FDA and from the published literature in HCV/HBV co-infected patients treated with DAAs between 22 November 2013 and 18 July 2016.
Of the cases reported, two patients died and one required a liver transplant, though FDA cautions that this number includes only cases submitted to FDA, so there are likely additional cases.
