[Complications in kidney transplantation].

DE NOVO DIABETES AND CARDIOVASCULAR RISK: Certain kidney transplant recipients who develop de novo diabetes have an unfavorable cardiovascular risk profile, comparable to patients with type 2 diabetes mellitus, with advanced age, dyslipidemia, obesity and high blood pressure. MYOCARDIAL INFARCTION IN THE PERIOPERATIVE PERIOD: Among kidney transplant recipients, those whose risk factors include male gender diabetes, age over 50 years and prior revascularization procedure for coronary artery disease have a higher risk for myocardial infarction in the perioperative period. The usefulness of anticoagulant or beta-blockers as preventive treatment for these high-risk patients remains to be determined. HYPERLIPIDEMIA: A retrospective analysis of 530 kidney transplant recipients demonstrated that a very significant proportion of those with dyslipidemia are not receiving appropriate care although their lipid profile is indicative of a high or very high cardiovascular risk. MASSIVE PROTEINURIA: An angiotensin II inhibitor, losartan, has been found to be effective against massive proteinuria (> 3.5 g/l) occurring after kidney transplantation. CALCINEURIN-INHIBITOR-INDUCED HEMOLYTIC UREMIA SYNDROME: Five to ten percent of patients given calcineurin inhibitors develop a hemolytic uremia syndrome. Sirolimus appears to be a very interesting alternative for immunoprophylaxys against acute rejection.
