Immune checkpoint inhibitors (ICIs) have transformed the field of oncology and improved outcomes in patients with difficult-to-treat malignancies. ICIs are monoclonal antibodies against cytotoxic T-lymphocyte-associated protein 4 (CLTA-4), programmed cell death protein 1 (PD-1), and programmed death ligand 1 (PD-L1) that restore T-cell immune surveillance of tumors, but also relax the regulation of self-immunity, which can result in the development of immune-mediated organ toxicities. Consequently, ICI-mediated hepatitis (IMH) can occur in up to 16% of patients and usually presents with a hepatocellular pattern of injury. It is thought to be more common in those who receive CTLA-4 monotherapy or combination regimens of anti-CTLA-4 and either PD-1 or PD-L1 inhibitors. [1] The Common Terminology Criteria for Adverse Events (CTCAE) categorizes grade 3 or 4 toxicity as high-grade IMH and defines them as alanine aminotransferase (ALT) and aspartate aminotransferase (AST) elevation >5-20 times the upper limit of normal (ULN) and >20 times ULN, respectively. [1] Alkaline phosphatase and total bilirubin elevations can also be observed, but they are infrequent. [2] Multiple societies recommend high-dose corticosteroids, 1-2 mg/kg/d of methylprednisolone equivalents, for the management of high-grade IMH. [2] Currently, these recommendations rely on expert opinion and small case series. Clinicians prefer to limit the use of high-dose steroids because of potentially higher rates of infection, hyperglycemia, low bone density, and uncertain effects on malignancy outcomes. [3,4] A retrospective cohort study by Li et al. provides much-needed data to inform the management of grade 3-4 IMH, including corticosteroid dosing, benefits of dose escalation, and frequency of adverse outcomes. [5] They analyzed a large patient cohort who developed grade 3-4 IMH after receiving one or more ICIs between 2010 and 2020. One hundred twenty-eight patients were initially treated with <1.5 mg/kg/d of methylprednisolone equivalents (the lower-dose group), whereas 87 patients were started on ≥1.5 mg/kg/d (the higher-dose group).
