“…RUCAM helped search for pharmacotherapy options of iDILI including cases of a subtype characterized by serological autoimmune features and diagnosed as druginduced autoimmune hepatitis (DIAIH), for which corticosteroids are the first choice of treatment as shown in a study that applied the updated RUCAM to exclude competing causes [179], perfectly done by also using a specific diagnostic algorithm of genuine autoimmune hepatitis (AIH) [180] in a separate control cohort of AIH [179]. Differentiation of DIAIH from the usual DILI is commonly well achieved [179][180][181][182], even if the two diagnostic algorithms of iDILI and AIH were used in combination for DIAIH [181,182], but under these conditions, preference should be given to the updated RUCAM [181] rather than the original RUCAM [182]. RUCAM-based studies showed DIAIH causally related to drugs [183] like antimicrobials [184,185], atorvastatin [183], augmentin [184], ceftriaxone [185], diclofenac [186], direct oral anticoagulants [179], hydralazine [186], irbesartan [187], infliximab [188,189], isoniazid [186], ketoprofen [184], methyldopa [186], minocycline [186], nimesulide [184], nitrofurantoin [186,188,190,191], non-steroidal antiinflammatory drugs [179,184,190,192], sorafenib [183], and statins…”
