    Abstract:
    BACKGROUND: Coronary allograft vasculopathy (CAV) is a progressive complication after cardiac transplantation and limits survival. Hyperlipidemia is a known risk factor for CAV, and pravastatin is effective in decreasing cholesterol levels in adults after transplantation. However, few data exist regarding lipid profiles and statin use after pediatric heart transplantation. We evaluated the prevalence of hyperlipidemia in pediatric heart transplant recipients and assessed the efficacy and safety of pravastatin therapy. METHODS: We performed a retrospective chart review of lipid profiles > or =1 year after surgery in 50 pediatric cardiac transplant recipients to assess the incidence of hyperlipidemia. Twenty of these patients received pravastatin for hypercholesterolemia. Their primary immunosuppression therapy was cyclosporine/prednisone plus either azathioprine or mycophenolate mofetil. We reviewed serial lipid profiles, creatinine phosphokinase, and liver enzymes. RESULTS: Overall, 36% of the patients (n = 50) had total cholesterol (TC) concentrations > 200 mg/dl and 52% had low-density lipoprotein (LDL) >110 mg/dL beyond 1 year after transplantation. Of the 20 treated with pravastatin, TC (236 +/- 51 vs 174 +/- 33 mg/dl) and LDL levels (151 +/- 32 vs 99 +/- 21 mg/dl) decreased significantly with therapy (p <.0001). We found no symptoms; however, 1 patient had increased creatinine phosphokinase. Liver enzyme concentrations remained normal in all. CONCLUSIONS: Hypercholesterolemia is prevalent in pediatric cardiac transplant recipients. Pravastatin therapy is effective in decreasing TC and LDL levels, seems to be safe, and is tolerated well. Further studies are necessary to determine whether pravastatin treatment is beneficial in decreasing CAV.
