title: Can the potential benefits of statins in general medical practice be extrapolated to liver transplantation?
abstract: Hypercholesterolemia is a common complication of liver transplantation and is a risk factor for cardiovascular disease after renal and heart transplant. The effect of hyperlipidemia after liver transplantation is less certain, but a less favorable outcome is to be expected. 3-Hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors or statins have proven efficacy in reducing serum cholesterol and mortality from cardiovascular disease in the general population. Early evidence shows that statins are safe and effective in treating hypercholesterolemia after liver transplantation. Studies in cardiovascular disease have shown that statins exhibit beneficial properties independent of lipid-lowering. These include anti-inflammatory effects and improvement in endothelial function. Recently, statins were shown to repress induction of major histocompatibility complex class II complexes by interferon-gamma, which in turn suppresses activation of T lymphocytes. Such effects may assume significance when using statins after solid-organ transplants. Pravastatin has been shown to reduce acute rejection after cardiac and renal transplantation and to also reduce natural killer cell cytotoxicity in these populations. It remains to be seen whether statins will demonstrate similar benefits after liver transplantation.
