Abstract

Abstract

Objective To explore the efficacy of different non-biological artificial liver supporting system on liver function failure by retrospective study.Methods One hundred and six patients with liver failure were selected, who were diagnosed in the Third People's Hospital of Kunming City from January, 2014 to January, 2015, and during this period 240 person-time of the artificial liver treatment were completed.The patients weredivided into two groups according to the types of artificial liver, 62 patients in plasma exchange group (referred as PE) , 44 patients in plasma exchange combined with hemodiafiltration group (referred as PE+HDF) .Before and after the artificial liver treatment, we recorded the artificial liver laboratory indexes of the patients and model for end-stage liver disease (MELD) score, so as to evaluate the efficacy of two groups of treatment.Results (1) For these two groups, after treatment, the serum total bilirubin (TBIL) , aspartate aminotransferase (AST) , alanine aminotransferase (ALT) , total bile acid (TBA) levels were significantly reduced, and the difference was statistically significant (P<0.05) ; (2) Total bilirubin and bile acid clearance rate after artificial liver treatment was equal to 1-after treatment before treatment, compared with the group of PE, total bilirubin and bile acid clearance rate of PE+HDF group was higher, and the difference was statistically significant (P<0.05) .After PE treatment, the clearance rates of total bilirubin and bile acid were 54.07±11.03% and 85.95±30.22% respectively;after PE+HDF treatment, the clearance rates of total bilirubin and bile acid were 63.03±11.15% and 92.40 ±40.13% respectively; (3) After treatment, prothrombin activity (PTA) index significantly increased and International Normalized Ratio (INR) value decreased both in PE group and PE+HDF group, and the difference of PTA and INR before and after treatment in each group was statistically significant (P<0.05) , suggesting that both the two models had significant effects on improving the coagulation function; (4) Compared with the group of PE, the promotion of the PTA in PE+HDF group was better, and the difference was statistically significant (P<0.05) ;The PTA increased by 88±65% in group PE while increased by 102±73% in PE+HDF group; (5) By comparing the changes of blood ammonia before and after treatment between the two groups, blood ammonia had no improvement after treatment in group HE;And blood ammonia dropped significantly after treatment in PE+HDF group, with the statistically significant difference before and after ammonia treatment (P<0.05) .Blood ammonia decreased by 50.58±23.58% after treatment in group PE+HDF; (6) Renal function was damaged after treatment compared with that before treatment in PE group, which could cause the serum sodium to increase and serum potassium to decrease, with the statistically significant difference (P<0.05) ;In group PE+HDF, the treatment could improve the renal function and correct hyponatremia and hyperkalemia, with statistically significant difference (P<0.05) ; (7) Model for end-stage liver disease (MELD) score decreased after treatment both in HE group and PE+HDF group, and the differences of each group before and after treatment were statistically significant (P<0.05) ;Compared with the group of PE, PE+HDF group improved more in the end-stage liver disease score, and the difference was statistically significant (P <0.05) .Conclusion Compared with plasma exchange, plasma exchange combined with hemodiafiltration can increase the removal of albumin bound toxins (total bilirubin and bile acid) , is more effective in ptomoting prothrombin activity, and increasing the clearance of small and middle molecules so that the treatment is more effective on patients with liver failure complicated with hepatic encephalopathy, liver and kidney syndrome and internal environment disorder, etc;Both plasma exchange and plasma exchange combined with hemodiafiltration can significantly improve the model of end-stage liver disease, and reduce the risk of death and improve prognosis, but plasma exchange combined with hemodiafiltration is better.
