What this trial studies

This study investigates the effects of different dietary interventions on living kidney donors prior to transplantation. Participants will be assigned to one of four dietary regimes: a fasting mimicking diet, a ketogenic diet, a dietary restriction of sulfur-containing amino acids, or a control diet. The study aims to identify molecular changes in kidney biopsy samples that may enhance stress resistance and protect against acute kidney injury (AKI). By understanding these mechanisms, the research seeks to improve outcomes for kidney donors and recipients.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old who are planned living kidney donors or recipients.

Not a fit: Patients who are vegetarian, have a low BMI, or have contraindications for enteral nutrition may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved kidney function and reduced risk of acute kidney injury in living kidney donors.

How similar studies have performed: While dietary interventions have shown promise in animal models, this specific approach in living kidney donors is novel and has not been extensively tested in clinical settings.
