Disease severity of acute liver injury caused by drug‐induced liver injury may affect the response to corticosteroid therapy

We read with great interest the article by Weber S and colleagues 1 . Because idiosyncratic drug-induced liver injury (DILI) is hard to distinguish from autoimmune hepatitis (AIH) of the acute liver injury, it is very important to establish parameter to identify the patients with idiosyncratic DILI from that with AIH. However, we have concerned that it may be potential limitation that numbers of the acute liver failure (ALF) patients is small in this study.
