Hepatitis b virus (HBV) related acute-on-chronic liver failure (ACLF) is a serious condition with high mortality rate in China. But there still lacks of effective therapies in treatment of HBV related ACLF, except liver transplantation. Non-bioartificial liver support system treatments may be effective due to previous clinical data. Plasma exchange (PE) and double plasma molecular adsorption system (DPMAS) are two common ways in clinical practice. This study is to investigate the clinical efficacy and safety of combination treatment of DPMAS and low volume PE in patients with HBV related ACLF. This study will be completed in 6 medical center. Two hundred patients with HBV related ACLF enrolled in this study are divided into trial group (DPMAS, low volume PE, and comprehensive internal medical treatment) and control group (comprehensive internal medical treatment). Symptoms, signs, laboratory tests results, adverse events, mortality rates are recorded from treatment baseline to 12 weeks.
This study is to investigate investigate the safety and efficacy of Double plasma molecular adsorption system with sequential low-dose plasma exchange in treating hepatitis B virus-related acute-on-chronic liver failure.
