In 2011, the Intractable Liver Diseases Study Group of Japan, established novel diagnostic criteria for “acute liver failure ”, and published the classification criteria for the etiologies of acute liver failure and late‐onset hepatic failure (LOHF) in 2013. According to this classification, HBV carriers showing acute hepatitis exacerbation were divided into 3 subgroups; asymptomatic or inactive HBV carriers without drug exposure, asymptomatic or inactive HBV carriers developing HBV reactivation during and after immunosuppressive therapies and/or antineoplastic chemotherapies and those with previously resolved HBV infection showing iatrogenic HBV reactivation. In an annual nationwide survey in 2013, however, a patient with previously resolved HBV infection was enrolled, in whom LOHF developed as a result of HBV reactivation despite in the absence of immunosuppressive therapies and/or antineoplastic chemotherapies. Thus, the study group revised the classification criteria in 2015; HBV carriers developing acute hepatitis exacerbation were classified into asymptomatic or inactive HBV carriers and patients with previously resolved HBV infection, and both groups were further sub‐classified into those receiving immunosuppressive therapies and/or antineoplastic chemotherapies and those without such drugs exposure.
