RESUMEN
BACKGROUND: Statins are widely used to decrease cholesterol and improve morbidity and mortality associated with coronary artery disease. Myopathy constitutes a rare but potentially life-threatening adverse reaction, which is related to plasma HMG-CoA reductase inhibitory activity. Therefore, the incidence of rhabdomyolysis increases dramatically when statins are co-administered with drugs that inhibit their hepatic transformation, such as cyclosporine or azoles. METHODS AND RESULTS: We present a case of severe rhabdomyolysis and acute renal failure induced by itraconazole in a heart transplant recipient chronically treated with cyclosporine and simvastatin. The literature with regard to the pathogenetic mechanisms and the clinical implications are reviewed. CONCLUSIONS: To avoid severe myopathy, cyclosporine levels should be monitored sooner than weekly intervals and statins should be discontinued or their dosage should be reduced, as long as azoles need to be prescribed in transplant recipients. Rhabdomyolysis and acute renal insufficiency should be promptly recognized and aggressively treated.
