Article Synopsis
  • - This study investigates the severity and characteristics of checkpoint inhibitor-induced hepatitis, a significant side effect of cancer immunotherapy, focusing on patients with severe liver injury (grade 3 and 4) based on the Common Terminology Criteria for Adverse Events (CTCAE).
  • - A retrospective analysis of 100 patients revealed varying severity classifications and outcomes, indicating that the CTCAE may not effectively assess liver injury severity compared to hepatology-focused classification systems.
  • - The findings suggest that using traditional hepatology scores could provide better insights and avoid issues like unnecessary steroid treatments and hindered re-administration of immune checkpoint inhibitors.

Transjugular Intrahepatic Portosystemic Shunt (TIPS) is an established procedure for the complications of portal hypertension, such as variceal bleeding, refractory ascites and hepatic hydrothorax. We report an original case of a renal transplant patient successfully treated with TIPS for portal hypertension due to sinusoidal obstructive syndrome (SOS) induced by azathioprine (AZA). By reporting this case, we wish to draw the attention of healthcare professionals managing organ transplant patients, especially nephrologists, to the possible occurrence of liver toxicity due to AZA, and to emphasize the role of TIPS as an effective therapeutic option for portal hypertension-related complications.

Background: Several cancer immunotherapies that target the PD-L1/PD-1 pathway show promising clinical activity in patients with hepatocellular carcinoma (HCC). However, the standard of care in first-line treatment with atezolizumab (anti-PD-L1 therapy) in combination with bevacizumab is associated with a limited objective response rate. Telomerase reverse transcriptase (TERT) activation meets the criteria of oncogenic addiction in HCC and could be actionable therapeutic target and a relevant tumor antigen.
