Effect of Propionic Acid on Immune Function in Children with Severe Kidney Disease

Official title: Impact of Propionic Acid on Regulatory T Cell Function in Children With Chronic Kidney Disease

Run by Charite University, Berlin, Germany · NCT05858437 · Data updated 2026-11-12

This study is testing if adding propionic acid to the diets of children with severe kidney disease can help improve their immune system and gut health while they are on hemodialysis.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are children aged under 18 years with stage 5 CKD who have been on hemodialysis for more than three months.

Probably not a fit

Patients with acute infections, malignancies, or those on immunosuppressive therapy may not benefit from this study.

What this trial studies

This study investigates the impact of dietary supplementation with propionic acid on the immune system and intestinal barrier function in children with stage 5 chronic kidney disease (CKD) undergoing hemodialysis. It is a multi-center, double-blind, randomized, and placebo-controlled intervention aimed at normalizing serum levels of propionic acid to reduce chronic inflammation, which is a significant risk factor for cardiovascular disease in CKD patients. The study will assess the function and abundance of regulatory T cells in response to propionic acid supplementation over a defined period.

Why it matters

Potential benefit: If successful, this intervention could improve immune function and reduce inflammation in children with CKD, potentially leading to better health outcomes.

How similar studies have gone: While the specific approach of using propionic acid supplementation in this context is novel, previous studies have shown positive effects of short-chain fatty acids on immune regulation.
