Beware of HCV and HEV in Patients with Suspected Drug-Induced Liver Injury

AbstractPurpose of ReviewWithout a specific biomarker, the diagnosis of drug-induced liver injury (DILI) relies on exclusion of other causes of liver injury. This review examines the importance of testing for hepatitis C (HCV) and hepatitis E (HEV) in patients with suspected DILI.Recent FindingsSeveral national DILI registries have reported HCV and HEV infection in patients initially diagnosed with DILI. Particularly in patients with suspected DILI who have acute hepatocellular liver injury, acute HCV and acute HEV infection should be considered even in the absence of traditional risk factors. For HCV infection, testing for HCV RNA and HCV antibody are recommended. For HEV, the high prevalence of HEV IgG antibody means that HEV IgM antibody testing is suggested to exclude this infection.SummaryThere should be a high clinical suspicion for acute HCV and HEV infection in patients with acute hepatocellular liver injury suspected of being due to DILI.
