Latent Viral Infection of Lymphoid Cells in Idiopathic Nephrotic Syndrome — Nephrovir  

NEPHROSIS, LIPOID Clinical Trial

Official title: Viral Infection of Lymphoid Cells Occuring at the First Manifestation of Idiopathic Nephrotic Syndrome

Status Completed

Clinical Trial Summary

The primary purpose of the study is to evaluate the association of a latent infection of lymphoid cells during the first manifestation of steroid sensitive nephrite syndrome. The thirty nine units of general pediatrics and pediatric nephrite covering the parisian area will participate to the study. We speculate that hybridization of the genome, or a part of the genome, of a virus in lymphoid cells is responsible specific changes of genes expression, leading to the development of the disease.

Clinical Trial Description

An additional blood volume will be sampled in patients and controls during a scheduled biological check-up for the initial disease and viral genome of EBV, CMV, HHV6, HHV7 as well as adenovirus will be searched for using PCR reaction in total blood DNA extract. The frequency of a latent hybridization of virus genome within human genome will be compared between patients with steroid sensitive nephrotic syndrome and controls matched for age and sex. Secondary studies will include a comparison of steroid dependency in nephrotic patients according to the occurence of a latent viral hybridization, the epidemiology of idiopathic nephrotic syndrome in the Parisian area and a pharmacogenetic analysis of steroid sensitivity and dependency. If necessary, the chromosomal localization of viral hybridization will be studied with fluorescence in situ hybridization using specific probes. ;
