Sickle cell intrahepatic cholestasis (SCIC) is a rare complication of sickle cell anemia, characterized by marked hyperbilirubinemia and acute hepatic failure with an often fatal course. However, the few reported adult cases that were treated with exchange transfusion had a favorable outcome. We herein describe a 48-year-old African-American man with hemoglobin S/B thalassemia and previously treated hepatitis C with compensated cirrhosis, who presented with a total bilirubin of 59.7 mg/dL and direct bilirubin of 43.6 mg/dL in the absence of choledocholithiasis. Despite an exchange transfusion and aggressive packed red blood cell transfusions, which successfully decreased the hemoglobin S levels to <15%, he perished from progressive hepatic and renal failure. Autopsy demonstrated extensive intrahepatocellular and intracanalicular cholestasis in a background of cirrhosis. Our case suggests that poor prognostic factors for adult SCIC patients treated with exchange transfusion may include older age and underlying hepatic disease.
镰状细胞性肝内胆汁淤积症(SCIC)是镰状细胞贫血的一种罕见并发症,其特征为显著的高胆红素血症和急性肝衰竭,病程往往致命。然而,少数接受换血治疗的成年病例预后良好。我们在此描述一名48岁的非裔美国男性,患有血红蛋白S/β地中海贫血,既往丙型肝炎已治愈,伴有代偿期肝硬化,此次就诊时总胆红素为59.7mg/dL,直接胆红素为43.6mg/dL,且无胆总管结石。尽管进行了换血治疗和积极的浓缩红细胞输血,成功将血红蛋白S水平降至<15%,但他最终因进行性肝肾功能衰竭死亡。尸检显示在肝硬化背景下存在广泛的肝细胞内和胆小管内胆汁淤积。我们的病例表明,接受换血治疗的成年SCIC患者预后不良的因素可能包括年龄较大和潜在的肝脏疾病。
