Clinical efficacy of plasma exchange therapy in treatment of liver failure / 临床肝胆病杂志

ABSTRACT

Objective To investigate the clinical efficacy of plasma exchange (PE)in the treatment of liver failure.Methods A retro-spective analysis was performed on the clinical data of patients with liver failure who were treated from January 2012 to June 2013 in our hos-pital.Thirty -three patients in PE group received PE in addition to medical comprehensive treatment,and 30 patients in control group were treated with medical comprehensive treatment.Clinical symptoms,complications,and the changes in biochemical markers of liver function were observed after 2 weeks of treatment,post -treatment outcomes were evaluated by 3 -month followed -up,and the influential factors for efficacy were analyzed.Experimental data were expressed as mean ±standard deviation,continuous data were compared by t test,and cate-gorical data were analyzed by chi -square test or Fisher′s exact test.Results Symptoms such as fatigue,poor appetite,and abdominal dis-tension were significantly relieved after PE.Post -treatment serum alanine aminotransferase (ALT)and total bilirubin (TBil)levels were significantly lower compared with pre -treatment levels (390.48 ±536.52 U /L vs 81.03 ±47.58 U /L and 479.27 ±130.01 μmol /L vs 244.64 ±151.05 μmol /L,P 0.05).Patients in PE group had a significantly higher improve-ment rate (χ2 =8.276,P <0.005)and a significantly lower mortality rate (χ2 =13.258,P <0.005)compared with the control group.The efficacy of PE was found to be correlated with pre -treatment TBil level,complications,bilirubin enzyme separation,and age ≥40 years (P <0.05).TBil and bilirubin enzyme separation were independent risk factors affecting the efficacy of PE (P <0.05,OR =1.01 and 8.75).Adverse reactions occurred in 8 cases during PE treatment,and disappeared after symptomatic treatment.Conclusion PE is a safe and effective treatment for liver failure,and holds promise for clinical application.TBil level and bilirubin enzyme separation are independ-ent risk factors affecting the efficacy of PE.
