Influence of tacrolimus and prednisone on serum lipids after liver transplantation.
BACKGROUND
Hyperlipidemia after orthotopic liver transplant is thought to be the result of the immunosuppression therapy given postoperatively. The purpose of this study was to evaluate serum lipid levels pretransplant, 4 months, and 12 months posttransplant.


METHODS
A retrospective chart review of 50 patients after liver transplantation was completed. Pretransplant serum lipid levels (triglyceride, cholesterol, and high-density lipoprotein [HDL]) were compared with values at 4 months and 12 months posttransplantation. Pretransplant serum lipid levels were compared using one factor analysis of variance (ANOVA) model. Values between the viral, alcohol, and cholestatic groups were compared using two-factor ANOVA model.


RESULTS
Of the 50 patients (22 females, 28 males) with a mean age of 52 years (range, 16 to 69 years), all 50 had completed their 12-month follow-up at the time of this study. The etiology of liver disease included: viral hepatitis (21), alcohol (8), primary biliary cirrhosis and sclerosing cholangitis (7), and others (14). The protocol for immunosuppression included tacrolimus and prednisone. Mean serum triglyceride levels included: 134 mg/dL pretransplant, 155 mg/dL at 4 months, and 169 mg/dL at 12 months posttransplant (p = .117). Mean total serum cholesterol levels included: 174 mg/dL pretransplant, 165 mg/dL at 4 months, and 163 mg/dL at 12 months posttransplant (p = .654). Mean HDL levels included: 39 mg/dL pretransplant, 45 mg/dL at 4 months and 44 mg/dL at 12 months posttransplant (p = .032). There was not a significant difference in serum lipids between the different categories of liver diseases.


CONCLUSIONS
Although a significant positive effect was observed with HDL, the present data show that total serum cholesterol and triglyceride did not change significantly over time after orthotopic transplantation. This is most likely related to the type of immunosuppressive therapy given posthepatic transplantation.
