摘要
Giant cell hepatitis associated with autoimmune hemolytic anemia (GCH-AIHA) is a rare disorder with unfavorable prognosis, affecting infants and young children. The mortality rate is high, complications of acute liver failure, sepsis, or liver transplantation can be responsible for fatal outcomes. An 18-month-old child who was diagnosed previously with autoimmune hemolytic anemia, developed acute hepatitis and acute liver failure concomitant to the relapse of the disease. GCH-AIHA is characterized by Coombs positive hemolytic anemia and progressive liver injury, histologically defined by widespread giant cell transformation. Liver biopsy was performed to establish the diagnosis, histological examination confirmed the presence of multinuclear, giant cell hepatocytes. Corticosteroid and azathioprine treatment were started. As a result of subsequent rituximab treatment and intravenous immunoglobulin therapy, acute liver failure and anemia gradually resolved. The exact background of the association of the two entities is still unknown, an autoimmune mechanism is suspected. Conventional immunosuppressive treatment with corticosteroid and azathioprine seems to be ineffective in most cases, therefore second- and third-line therapies are required. Since the introduction of the anti-CD20 rituximab therapy, the prognosis of GCH-AIHA has improved significantly. Orv Hetil. 2023; 164(36): 1432-1436.
