Background: Kidney donation is associated with few adverse outcomes in living donors. The aim of this study was to evaluate the outcomes of living kidney donors and the utility of creatinine-based equations to predict chronic kidney disease. Methods: The study population was selected among 154 living kidney donors from 2001 to 2009. Seventy-eight patients underwent medical consultation to review demographic data and perform laboratory evaluations. Estimated glomerular filtration rate (GFR) values were obtained by three equations: Modification of Diet in Renal Disease (MDRD), Cockcroft-Gault (C-G) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI). Receiver operating characteristic (ROC) analysis was performed to determine the area under the curve of each equation to predict evolution to chronic kidney disease. Results: The overall median age was 39 years including 64% of women subjects. The mean follow-up after kidney donation was 65 ± 34 months. During follow-up, 20.5% of patients developed hypertension. Serum creatinine values above 1.5 mg/dL were detected in 14.1% of cases. Dyslipidemia was present in 33.3% of donors at the last follow-up. According to measured creatinine clearance and the C-G equation, only four and six donors had renal failure (defined as GFR < 60 mL/min), a number that increased to 23 (29.4%) when considering the MDRD or CKD-EPI equations (P <.05). ROC curves performed to explore the GFR measurements to predict renal failure occurrence after donation showed the CKD-EPI to be the only one with a significant area under the curve (0.7442, P =.003). Conclusion: Living kidney donors should receive careful long-term follow-up. Assessment of renal function before donation using CKD-EPI creatinine-based equations must be performed preferentially. A careful approach should be adopted for the detection and treatment of other complications such as hypertension and dyslipidemia. © 2011 Elsevier Inc.
