Long-term clinical outcomes in living kidney donors: a comparative study with matched controls

Area of Science:

• Nephrology
• Transplantation Immunology
• Clinical Outcomes Research

Background:

• Living kidney donation is a vital procedure for end-stage renal disease treatment.
• Understanding long-term health implications for donors is crucial for ethical practice and donor well-being.
• Pre-donation factors may influence post-donation health trajectories.

Purpose of the Study:

• To evaluate the long-term clinical outcomes in living kidney donors after nephrectomy.
• To identify pre-donation factors (age, BMI) associated with adverse outcomes.
• To assess the impact of kidney donation on hypertension, diabetes, proteinuria, and glomerular filtration rate (GFR).

Main Methods:

• A cohort study involving 87 living kidney donors and 100 matched controls.
• Pre- and post-donation monitoring of blood pressure, BMI, GFR, and proteinuria.
• Comparative analysis of outcomes within donor and control groups and between the groups.

Main Results:

• Nephrectomy was identified as an independent risk factor for increased hypertension incidence.
• A significant, persistent GFR reduction (>20%) was observed post-nephrectomy.
• Higher donor age and elevated post-donation BMI correlated with increased risks of hypertension and diabetes.

Conclusions:

• Kidney donation is associated with an increased risk of developing hypertension and a decline in GFR.
• Age at donation and post-donation BMI are critical factors influencing long-term donor health.
• Long-term follow-up and careful donor selection are essential to mitigate risks associated with kidney donation.
