AIM:To investigate the impact of renal and graft function on post-transplant hyperlipidemia(PTHL) in living donor liver transplantation(LDLT).METHODS:A total of 115 adult patients undergoing LDLT from January 2007 to May 2009 at a single center were enrolled.Data were collected and analyzed by the China Liver Transplant Registry retrospectively.PTHL was defined as serum triglycerides ≥ 150 mg/dL or serum cholesterol ≥ 200 mg/dL or the need for pharmacologic treatment at the sixth month after LDLT.Early renal dysfunction(ERD) was defined as serum creatinine ≥ 2 mg/dL and/or the need for renal replacement therapy in the first post-transplant week.RESULTS:In 115 eligible patients,the incidence of PTHL was 24.3%.Recipients with PTHL showed a higher incidence of post-transplant cardiovascular events compared to those without PTHL(17.9% vs 4.6%,P = 0.037).Serum creatinine showed significant positive correlations with total serum triglycerides,both at posttransplant month 1 and 3(P 0.01).Patients with ERD had much higher pre-transplant serum creatinine levels(P 0.001) and longer duration of pre-transplant renal insufficiency(P 0.001) than those without ERD.Pretransplant serum creatinine,graft-to-recipient weight ratio,graft volume/standard liver volume ratio,body mass index(BMI) and ERD were identified as risk factors for PTHL by univariate analysis.Furthermore,ERD [odds ratio(OR) = 9.593,P 0.001] and BMI(OR = 6.358,P = 0.002) were identified as independent risk factors for PTHL by multivariate analysis.CONCLUSION:Renal function is closely associated with the development of PTHL in LDLT.Post-transplant renal dysfunction,which mainly results from pre-transplant renal insufficiency,contributes to PTHL.
