Living kidney donors require long-term monitoring for potential complications like hypertension and dyslipidemia. The CKD-EPI equation is recommended for assessing kidney function to predict chronic kidney disease risk.
Area of Science:
- Nephrology
- Transplantation Medicine
- Public Health
Background:
- Living kidney donation is generally safe with minimal adverse outcomes.
- Long-term health outcomes for living kidney donors require ongoing evaluation.
- Assessing the predictive utility of creatinine-based equations for chronic kidney disease (CKD) in donors is crucial.
Purpose of the Study:
- To evaluate the long-term health outcomes of living kidney donors.
- To assess the effectiveness of different creatinine-based equations in predicting CKD in kidney donors.
- To identify potential complications following kidney donation.
Main Methods:
- Retrospective analysis of 154 living kidney donors (2001-2009).
- Demographic data and laboratory evaluations were collected for 78 donors.
- Estimated glomerular filtration rate (GFR) calculated using MDRD, Cockcroft-Gault (C-G), and CKD-EPI equations.
- Receiver operating characteristic (ROC) analysis used to compare equation performance in predicting CKD.
Main Results:
- Median donor age 39 years, 64% female; mean follow-up 65 months.
- Hypertension (20.5%), elevated creatinine (14.1%), and dyslipidemia (33.3%) were observed.
- CKD-EPI and MDRD equations identified significantly more donors with GFR < 60 mL/min compared to C-G (29.4% vs. <1.5%).
- CKD-EPI demonstrated a significant area under the ROC curve (0.7442, P = .003) for predicting renal failure.
Conclusions:
- Living kidney donors necessitate comprehensive long-term follow-up care.
- The CKD-EPI equation is the preferred method for assessing renal function and predicting CKD risk in donors.
- Vigilant management of hypertension and dyslipidemia is essential for living kidney donor health.

One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...
