Aim. Immune checkpoint inhibitors (ICIs) have improved the survival rate of patients carrying various malignant neoplasms. Despite their efficacy, ICIs occasionally induce liver injury as an immune-related adverse event (irAE). This study aimed to reveal the clinical features of the hepatic irAE in Japanese patients. Methods. Among 387 patients treated with ICIs, those who developed drug-induced liver injury were investigated. We also describe the histological findings and clinical courses of four patients with hepatic irAE who underwent liver biopsy. Results. Among the 56 patients with all-grade liver injury, only 11 (19.6%) showed hepatocellular-type liver injury, which resembled autoimmune hepatitis. Thirty-four patients (60.7%) developed cholestatic or mixed-type liver injury, although only one patient showed abnormal image findings in the bile duct. Most patients with grade ≤2 liver injury improved spontaneously, while two patients with biliary dysfunction required ursodeoxycholic acid or prednisolone. Among eight patients with grade ≥3 liver injury, three required no immunosuppressants and five were treated with prednisolone (three of five patients required other types of immunosuppressants). Four patients in the case series showed diverse clinical features in terms of hepatotoxic pattern, symptoms, and the interval time between the initiation of immunotherapy and the onset of the hepatic irAE. Conclusions. Our findings suggest that ICIs could cause microscopic biliary disorder without any abnormal image finding. Because the hepatic irAE presents diverse clinical features, liver biopsy is recommended to provide appropriate treatments.

341 Background: In patients with hepatocellular carcinoma (HCC) and baseline liver dysfunction, hepatic immune-related adverse events (HIRAEs) during immunotherapy have not been adequately characterized and their impact on subsequent treatment outcomes is not known. Methods: 40 patients with advanced/unresectable HCC and Child Pugh score A have been enrolled in first and second-line clinical trials of anti-programmed cell death protein 1 (PD-1) monoclonal antibodies (mAbs). HCC etiologies were: hepatitis C (32.5%), hepatitis B (7.5%), alcohol abuse (27.5%), other (32.5%). 7 received anti-PD-1 mAbs alone and 33 received combined regimens that included anti-PD-1 mAbs plus either anti-cytotoxic T lymphocyte antigen 4 (30.4%) or tyrosine kinase inhibitors (TKIs) (54.5%), or both (15.1%). We reviewed their liver function tests and HIRAEs onset was related to time to treatment failure (TTF). Results: Overall, 12 patients (30%) developed grade ≥ 3 hepatitis according to Common Toxicity Criteria for Adverse Events v. 4.03, resulting in 4 cases of grade 2 drug-induced liver injury per DILI Working Group criteria. Time between therapy initiation and hepatitis onset was 1.4 months (0.4-2.8) and median peak aminotransferase (AT) level was 258 IU/L (85-869). Out of 6 permanent treatment discontinuations due to adverse events (AEs), 4 were linked to hepatitis. Higher AT median levels at baseline were significantly linked to grade ≥ 3 hepatitis compared with lower grades (95 IU/L vs. 36 IU/L, respectively; p = 0.008). Etiology, age, treatment did not predict HIRAEs onset. TTF in patients in patients with grade ≥ 3 hepatitis was shorter than in the whole cohort (1.4 vs. 3.8 months, p = 0.041), while overall survival did not differ (p = 0.125). Conclusions: We observed a 30% incidence of clinically significant HIRAEs. HIRAEs represent the most frequent AEs leading to treatment discontinuation in patients with HCC undergoing treatments with immune checkpoint inhibitors. Baseline AT levels may identify patients at increased risk of grade ≥ 3 hepatitis.

Acute Hypercapnic Respiratory Failure

Immune checkpoint inhibitors have revolutionised cancer therapy in the past decade. Although they have been indicated to treat a diverse range of malignant neoplasms, they are also associated with various immune-related adverse effects. We report the case of a 74-year-old man with a history of urothelial carcinoma who had atezolizumab-induced myocarditis and myositis resulting in acute hypercapnic respiratory failure, despite the discontinuation of atezolizumab and aggressive treatment with corticosteroids. This case highlights the importance of a multidisciplinary approach for early diagnosis and treatment of immune-related adverse events. Physicians must be aware of the risks associated with immune checkpoint inhibitors and have a basic knowledge regarding their management.
