In the last few years, immune checkpoint inhibitors (ICIs) have become major therapeutic agents for the treatment of advanced hepatocellular carcinoma (HCC). However, immunotherapy can activate hepatitis B virus (HBV), and immune clearance may lead to liver failure and even life-threatening conditions. Here we report a case of HCC with HBV-related cirrhosis that caused severe liver injury and rapidly progressed to fatal acute-on-chronic liver failure (ACLF) after only once application of camrelizumab; the patient underwent serological conversion of hepatitis B surface antigen (HBsAg) with liver injury. The patient's condition progressed rapidly. We added corticosteroids and applied plasma dialysis, along with tenofovir alafenamide (TAF) to control HBV. However, the patient eventually died of liver failure. To our knowledge, there are few reports of HBsAg clearance due to ICIs accompanied by fatal acute-on-chronic liver failure shortly after ICIs initiation. These results suggest that ICIs can cause fatal liver injury in a short term; in patients with chronic HBV infection, ICIs use may promote serological conversion of HBsAg.
在过去几年中,免疫检查点抑制剂(ICIs)已成为治疗晚期肝细胞癌(HCC)的主要治疗药物。然而,免疫疗法可激活乙型肝炎病毒(HBV),免疫清除可能导致肝衰竭甚至危及生命的情况。在此,我们报告一例HBV相关性肝硬化的HCC患者,该患者在仅一次应用卡瑞利珠单抗后发生严重肝损伤,并迅速进展为致命的慢加急性肝衰竭(ACLF);患者出现肝损伤伴乙型肝炎表面抗原(HBsAg)血清学转换。患者病情进展迅速。我们加用了皮质类固醇并进行了血浆透析,同时应用替诺福韦艾拉酚胺(TAF)来控制HBV。然而,患者最终死于肝衰竭。据我们所知,很少有关于ICIs导致HBsAg清除并在开始ICIs后不久伴有致命性慢加急性肝衰竭的报道。这些结果表明,ICIs可在短期内导致致命性肝损伤;在慢性HBV感染患者中,使用ICIs可能促进HBsAg的血清学转换。
