RESUMO
The National Kidney Foundation has developed guidelines for diagnosis and classification of chronic kidney disease (CKD) but it is not known whether they are applicable to renal transplant patients. This study analyzed the prevalence, the complications, and the influence of the CKD stage on the presence of complications in 506 stable transplant recipients. The mean age of the patients was 52.9 +/- 12 years, 34% were men, and the mean time after transplantation was 9.56 +/- 6.18 years. CKD was present in 90.3% with 9.9% were in CKD stages 4 or 5 with glomerular filtration rates lower than 30 mL/min per 1.73 m(2). The prevalence of anemia, phospho-calcium metabolism disorders, hypertriglyceridemia, and hypertension increased with the stage of CKD. We concluded that CKD and the complications of CKD were highly prevalent in renal transplant recipients. The classification of renal transplant patients by CKD stage may help clinicians to identify patients at increased risk and to target appropriate therapy to improve outcomes.
