混合型人工肝支持系统治疗慢性重型肝炎

目的 评价混合型人工肝支持系统治疗慢性重型肝炎患者的临床疗效。方法 应用内含5×10~9以上猪肝细胞的生物反应器结合血浆置换装置,构建混合型人工肝支持系统(HALSS),并用于治疗15例慢性重型病毒性肝炎患者。结果 每次治疗后患者临床症状不同程度减轻,乏力、腹胀明显改善,腹水减少。总胆红素在混合型人工肝支持系统治疗后由(493.5±139.8)μmol/L降至(250.9±91.3)μmol/L,凝血酶原活动度由(24.5±8.4)％升至(30.6±6.3)％。15例患者中11例经混合型人工肝支持系统治疗肝细胞迅速坏死得到控制,最终好转出院,4例患者病情无好转死亡。15例患者治疗中未发生严重不良反应。结论 混合型人工肝支持系统对于慢性重型肝炎是一种有效的辅助支持和治疗手段。

Study of severe hepatitis treated with a hybrid artificial liver support system

OBJECTIVES: To evaluate the efficacy of a hybrid artificial liver support system in the treatment of chronic severe hepatitis. METHODS: The hybrid artificial liver support system (HALSS) consisted of a bioreactor containing more than 5 x 10(9) porcine hepatocytes and plasma exchange device. 15 patients with chronic severe viral hepatitis were treated with the hybrid system. RESULTS: All the patients experienced a reduction in symptoms, such as fatigue, abdominal distention or ascites. After each treatment serum total bilirubin decreased markedly (from 493.5 micromol/L+-139.8 micromol/L to 250.9 micromol/L+-91.3 micromol/L, t=8.695, P<0.001), while prothrombin activity increased (from 24.5%+-8.4% to 30.6%+-6.3%, t=3.325, P<0.01). There were 11 patients whose progress of hepatocytes necrosis stopped after HALSS treatment, and finally they recovered completely. Four patients died of their worsen conditions. No serious adverse events were noted in the 15 patients. CONCLUSION: HALSS is a reliable hepatic support device for chronic severe hepatitis.
