Observation of Alterations in Kidney Function, Immune System and Gut Mircobiota After Living Donor Kidney Transplantation

Observational Charite University, Berlin, Germany · NCT05570929

What this trial studies

This observational study examines kidney function, immune response, and gut microbiota in pairs of living kidney donors and recipients who reside together. Participants will be monitored before and 24 weeks after the kidney transplant, with assessments of kidney function, body composition, blood pressure, gut microbiome diversity, and immune cell states. The study aims to understand the interactions between these factors and their impact on kidney health post-transplant.

Who should consider this trial

Good fit: Ideal candidates are individuals with a Body Mass Index between 18.5 and 34.9 kg/m2 who are planned living kidney donors or recipients.

Not a fit: Patients with significant heart, lung, liver, or kidney diseases, or those with acute infections or a vegan diet may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance our understanding of kidney transplant outcomes and improve post-transplant care for patients.

How similar studies have performed: While similar observational studies have been conducted, this specific multi-omics approach in living donor-recipient pairs is relatively novel.
