Study of severe hepatitis treated with a hybrid artificial liver support system / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVES</b>To evaluate the efficacy of a hybrid artificial liver support system in the treatment of chronic severe hepatitis.</p><p><b>METHODS</b>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.</p><p><b>RESULTS</b>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.</p><p><b>CONCLUSION</b>HALSS is a reliable hepatic support device for chronic severe hepatitis.</p>
