Metabolic Syndrome After Kidney Transplantation

BackgroundMetabolic syndrome (MS) includes some risk factors for development of diabetes and cardiovascular disease, obesity (BMI > 30), high triglycerides, low HDL cholesterol, hypertension and impaired glucose tolerance. Following the definition of the Adult Treatment Panel III criteria, a diagnosis of MS was established when 3 or more factors were present. In renal transplan patients MS has been reported to negatively influence both patient and graft survivals. The present study sought to verify the effect of MS among our cases.Methods298 cadaveric renal transplant recipients operated between January 1, 1996 and December 31, 2001 with absence of diabetes before transplantation, stable renal function 1 year posttransplantation and at least 4 years follow up were retrospectively evaluated from the end of the first post-operative year.Results50 patients out of 298 (16,7%) had MS at the beginning of the study, including 37 of them with 3 and 13 with 4 risk factors. Only one patient with MS died of cardiovascular disease. Graft failure was observed in 23.5% MS patients versus 9,7% patients without the Syndrome (p:n.s.) Only Creatinine and the incidence of Cardiovascular Diseases at 4 years were statistically higher in MS patients (P < .001).ConclusionsThese results suggested that MS is a risk factor for increasing CVD morbidity and decreased graft function, but early treatment of risk factors as soon as they become apparent can limit the adverse effects on patient and graft survival.
