Interest of Follicular Helper Lymphocytes / Regulatory Follicular Helper Lymphocytes Ratio in IgA Nephropathy
Sponsor: Centre Hospitalier Universitaire de Besancon
Summary
This study aims to investigate the relevance of the Tfh/Tfr (Follicular helper T cells/ Follicular regulatory T cells) ratio in patients with IgA nephropathy: * To identify a differential expression of the Tfh/Tfr ratio in patients considered stable or progressive * To predict, at diagnosis, the clinical evolution of the disease (progressive or stable form) in the first year.
