Acute renal allograft rejections, a role for statins?

Abstract

Acute rejection of kidney allografts during the first months following transplantation is one of the most important risk factor for long-term graft failure. Some small open studies have indicated that 3-hydroxy-3-methylglutaryl coenzyme A (HMG-Co-A), statins, might act as immunosuppressive agents, and reduce acute rejection rates. Moreover, the use of statin in transplant recipients is quite common, despite no data from prospective large multi-centre studies are available to demonstrate any beneficial effect for acute rejections or long-term cardiovascular protection in this population. In this overview, recent clinical and experimental data will be provided for assessing statins as immunosuppressive agents. Although in vitro studies have provided a theoretical basis for the use of statins as immunosuppressive agents, more recent clinical placebo controlled studies have failed to confirm the initial optimism of this effect of statins.
