Protective effect of salvianolate against bile duct injury after dcd donor liver transplantation / 解放军医学杂志

ABSTRACT

Objective To investigate the protective effect of salvianolate against bile duct injury after donation after cardiac death (DCD) liver transplantation and its clinical application prospect. Methods Sixty recipients of DCD liver transplantation were randomly divided into two groups with 30 cases in each group. Salvianolate (250mg/d) was given daily for 14 days after operation in treatment group, and the same amount of normal saline was given in control group. The therapeutic regimen of anti-rejection and anti-infection is the same between the two groups. The incidence of early graft dysfunction (EAD), and the serous levels of total bilirubin (TB), alkaline phosphatase (ALP), γ-glutamyltransferase (GGT), total bile acid (TBA) 1 month, 6 months and 12 months after liver transplantation were compared between the two groups. Also, the platelets (PLT), prothrombin time (PT), activated partial prothrombin time (APTT) and fibrinogen (FIB) were compared between the two groups at 2 weeks after operation. Results There was no significant difference in baseline parameters between the two groups (P>0.05). Compared with the control group, the incidence of EAD was decreased in treatment group, but there was no significant difference [10.0%(3/30) vs. 23.3%(7/30), P=0.166]. The serous levels of TB, ALP, GGT and TBA in treatment group were lower than those in control group 1 month, 6 months and 12 months after operation [TB 1 month, (28.5±17.0)μmol/L vs. (39.8±20.1)μmol/L, P=0.025; 6 months, (24.5±10.6)μmol/L vs. (33.3±16.4) μmol/L, P=0.018; 12 months, (19.8±9.5)μmol/L vs. (26.4±14.1)μmol/L, P=0.037, ALP 1 month, (147.3±76.9)U/L vs. (187.6±70.9)U/L, P=0.039; 6 months, (163.0±61.4)U/L vs. (198.1±51.6)U/L, P=0.020; 12 months, (167.9±59.9)U/L vs. (200.2±56.2)U/L, P=0.036, GGT 1 month, (83.9±49.5)U/L vs. (113.6±61.1)U/L, P=0.043; 6 months, (130.9±48.7)U/L vs. (169.7±77.0)U/L, P=0.023; 12 months, (154.7±45.1)U/L vs. (182.5±59.8)U/L, P=0.047, TBA 1 month, (6.6±2.1)μmol/L vs. (8.0±2.4)μmol/L, P=0.016; 6 months, (9.5±2.2)μmol/L vs. (12.1±3.4)μmol/L, P=0.001; 12 months, (12.5±2.7)μmol/L vs. (5.6±3.8)μmol/L, P=0.001]. However, there was no significant difference in PLT, PT, APTT and FIB between two groups [PLT (148.6±88.6)×109/L vs. (152.8±74.4)×109/L, P=0.843; PT (12.9±1.1)s vs. (13.0±1.1)s, P=0.617; APTT (34.6±3.7)s vs. (34.9±3.4)s, P=0.716; FIB (3.4±0.6)g/L vs. (3.2±0.6)g/L, P=0.270, repectively]. Conclusions Salvianolate has a protective effect against bile duct injury after DCD liver transplantation, and does not increase the risk of postoperative bleeding.
