abstract: OBJECTIVE
  To investigate the application and security of plasmapheresis combined with hemofiltration in the treatment of severe liver disease in middle and late pregnancy.
  
  
  METHODS
  Clinical data of 29 patients of middle and late pregnancy with severe liver disease from March 2009 to November 2013 in the Third Affiliated Hospital of Sun Yat-sen University was analyzed retrospectively. According to the therapeutic schedule, patients were divided into control group (n=16, 18-29 years old, median age of 24 years old) and treatment group (n=13, 21-28 years old, median age of 25 years old). The informed consents of all patients were obtained and the ethical committee approval was received. The control group was given the treatment of resisting infection, protecting liver, reducing jaundice, supplying albumin and globulin, infusing blood coagulation and so on. The treatment group was given plasmapheresis and hemofiltration on the basis of the above-mentioned treatment. The differences of major clinical indicators such as MELD scores, APACHEII scores, total bilirubin (TB), albumin (ALB), prothrombin time activity (PTA) , fasting blood glucose (FPG), serum creatinine (Scr) of peripheral venous blood and arterial lactic acid (Lac) in patients of two groups were observed 6 hours before and 1, 3, 5 days after the treatment. The major clinical indicators in patients of two groups were compared by t test and the clinical efficient were compared by χ² test.
  
  
  RESULTS
  There were no statistical differences of the clinical indicators between the two groups 6 hours before the treatment (all P>0.05). The MELD scores, APACHEII scores, TB, ALB, PTA, FPG, Scr, Lac were (25 ± 6) scores, (22 ± 5) scores, (197 ± 69) µmol/L, (30 ± 7) g/L, (55 ± 24)%, (5.7 ± 2.4) mmol/L, (111 ± 42) µmol/L, (2.3 ± 0.6) mmol/L in treatment group 1 day after treatment, and were (33 ± 8) scores, (30 ± 7) scores, (299 ± 113) µmol/L, (24 ± 6) g/L, (33 ± 11)%, (3.7 ± 1.7) mmol/L, (165 ± 82) µmol/L, (4.4 ± 1.5) mmol/L in control group, which improved significantly in the treated group compared to those in the control group. There was also significant improvement in those posttreatment d3, and 5 lab findings in the treatment group (P<0.05). The effective rate was higher in the treatment group (92%, 12/13) than the control group (56%, 9/16) (χ² =4.215, P<0.05). Kaplan-Meier analysis showed the combined treatment could significantly improve the 42 d survival rate in postpartum patients with liver function failure. One patient had transitional hypotension after plasma infusion and hemofiltration in the treatment group, but the blood pressure returned to normal 1 h after small dose of vasoconstrictor.
  
  
  CONCLUSIONS
  The therapeutic effect of plasmapheresis combined with hemofiltration on the treatment of severe liver disease in middle and late pregnancy is safe and effective, and it could improve the clinical outcomes and survival rate.
