Plasma Exchange and Continuous Hemodiafiltration in Treatment of Wilson's Disease-related Liver Failure

Third Affiliated Hospital, Sun Yat-Sen University60 enrolled

Overview

This study is to investigate the clinical efficacy of artificial liver support system using combination of plasma exchange and continuous hemodiafiltration in treatment of Wilson's Disease - related liver failure. 30 patients will receive treatment of plasma exchange and continuous hemodiafiltration and internal medicine. 30 patients will receive treatment of internal medicine.

Wilson's disease (WD) is an inherited disorder in which defective biliary excretion of copper leads to its accumulation, particularly in liver and brain. Presenting symptoms of liver disease can be highly variable, ranging from asymptomatic, with only biochemical abnormalities, to overt cirrhosis with all its complications. Acute liver failure (ALF) presentation is the most dramatic and may arise with catastrophic suddenness. It is considered rare, constituting only 3% of ALF cases in the pediatric ALF series in USA and associated with a high mortality reaching 95%. Patients with acute liver failure due to WD require liver transplantation, which is lifesaving. Kido J et al reported clinical outcomes of patients with liver failure were improved by artificial liver support system using combination of plasma exchange and continuous hemodiafiltration. So the investigators design this protocol: 30 patients will receive treatment of plasma exchange and continuous hemodiafiltration and internal medicine, 30 patients will receive treatment of internal medicine.

Interventions

artificial liver support systemOTHER

Patients will receive the treatment of artificial liver support system using combination of plasma exchange and continuous hemodiafiltration and internal medicine. The volume of fresh frozen plasma used in plasma exchange is 2000 millilitre. The time for continuous hemodiafiltration is about 8 hours.

Outcomes

Primary Outcomes

survival rate

Whether patients will survive is observed in the follow-up.

Time frame: 48 weeks

Secondary Outcomes

liver function improvement

Symptoms (i.e. fatigue, appetite, nausea, vomiting, jaundice, consciousness) and laboratory tests (i.e. blood cells, alanine transaminase, total bilirubin, prothrombin time, creatinine, ceruloplasmin, serum copper) are observed in the follow-up.

Time frame: 48 weeks
