Investigating T cell ratios in patients with IgA nephropathy

Official title: Interest of Follicular Helper Lymphocytes / Regulatory Follicular Helper Lymphocytes Ratio to Characterize and Predict Poor Prognosis Forms in IgA Nephropathy: an Exploratory Proof-of-concept Study

Run by Centre Hospitalier Universitaire de Besancon · NCT05791162 · Data updated 2026-11-12

This study is testing if measuring certain types of immune cells in the blood can help doctors tell the difference between stable and worsening IgA nephropathy in patients.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals with histologically confirmed IgA nephropathy and a minimum follow-up of five years or newly diagnosed patients during the study.

Probably not a fit

Patients with legal incapacity, those without social security coverage, or pregnant individuals may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study examines the ratio of follicular helper T cells to regulatory follicular helper T cells in patients diagnosed with IgA nephropathy. It aims to differentiate between stable and progressive forms of the disease by analyzing blood and urine samples. The study will also seek to predict the clinical evolution of the disease within the first year of diagnosis. Participants will include patients with confirmed IgA nephropathy and control patients with other kidney conditions.

Why it matters

Potential benefit: If successful, this study could lead to improved prognostic tools for patients with IgA nephropathy, allowing for better management of the disease.

How similar studies have gone: While the specific approach of analyzing Tfh/Tfr ratios in IgA nephropathy is novel, similar studies in other conditions have shown promise in understanding immune responses.
