Use of HMG-CoA Reductase Inhibitors after Kidney and Heart Transplantation: Lipid-Lowering and Immunosuppressive Effects.
Hypercholesterolaemia is common in patients treated with cyclosporin after kidney and heart transplantation; coronary vasculopathy, graft atherosclerosis or cardiovascular complications are the most frequent causes of mortality. Coronary heart disease has been attributed to hypercholesterolaemia and has been identified as a major risk factor of long term graft outcome in patients after kidney transplantation. HMG-CoA reductase inhibitors have been proven to be effective in lowering serum cholesterol concentrations in kidney and heart graft recipients receiving long term cyclosporin immunosuppression, and are therefore the drugs of choice in patients requiring treatment for hypercholesterolaemia after organ transplantation. The hydrophilic HMG-CoA reductase inhibitors, such as pravastatin and fluvastatin, should be distinguished from the lipophilic agents, lovastatin and simvastatin, with regard to toxicity and accumulation. Maximal doses of drugs in the latter group should be avoided, whereas the former have been administered at high dosages over prolonged periods of time without adverse effects. Recent preliminary data indicate that treatment with pravastatin not only decreases serum cholesterol but may have beneficial effects on the incidence, recurrence and severity of rejection episodes after kidney and heart transplantation.
