Hepatotoxicity and virological breakthrough of HCV following treatment with sofosbuvir, daclatasvir, and ribavirin in patients previously treated for tuberculosis.

The prevalence of hepatitis C virus/tuberculosis (HCV/TB) coinfection has not been estimated globally but few studies highlight the risk of hepatotoxicity following TB treatment or HCV treatment. Previously reported data highlights the risk of drug-induced hepatotoxicity associated with three of the first-line anti-TB agents: rifampin, isoniazid, and pyrazinamide specifically in patients coinfected with HIV and HCV. Thus far, direct-acting antiviral (DAA) drug-induced hepatotoxicity has not been reported in the literature but herein, we observed an unusual case of HCV virological breakthrough and hepatoxicity during treatment with DAA drugs in a patient who has previously been successfully treated for TB.
