    Abstract:
    The metabolic syndrome (MS) is a known cardiovascular risk factor in the general population and a common problem among renal transplant recipients. This study investigated whether MS after renal transplantation affected long-term graft function. We included 112 transplants at our center between 2000 and 2002. We excluded patients with the presence of pretransplant diabetes or nonstable renal function at 1 year after transplantation. We evaluated parameters such as demographic features, medications, smoking history, body mass index, daily proteinuria, blood pressure, number of HLA mismatches, number of acute rejection episodes, delayed graft function, and laboratory parameters. Patients were followed for a mean of 69.86 +/- 21.94 months. The prevalence of MS was determined using the National Cholesterol Education Program-Adult Treatment Panel III criteria. At 1 year after transplant, 28.6% of subjects had MS, whereas only 10.7% had MS before transplantation. Among 27.7% of patients graft failure had occurred during the follow-up; MS was more frequent among these individuals compared with those displaying stable renal function (51.6% vs 19.8%; P = .002). Older donor age, delayed graft function, acute rejection episodes, smoking history, MS, proteinuria, serum creatinine level, and C-reactive protein were associated with graft failure. Upon multivariate Cox regression analysis, patients with MS at 1 year after transplantation showed an increased risk for graft failure (relative risk, 0.22; 95% confidence interval, 0.06-0.75; P = .016). Older donor age and proteinuria level were other independent risk factors for graft failure. The MS was a prominent risk factor for graft failure. Because MS is a cluster of modifiable risk factors, early identification of patients at risk and intervention in due time may improve graft survival.
