Validation of Biomarkers of Diabetic Nephropathy in Type I Diabetic Children

About 30 to 40% of patients suffering from type I diabetes are at risk of developing a diabetic nephropathy (DN) leading more or less rapidly to an end-stage renal disease. Nowadays, the microalbuminuria is the most often used clinical parameter for possible onset of DN. However, it is a late (because it permits to detect a renal disease already present), non-specific and low sensitive biomarker. Therefore the main objective of this study is to identify early urinary biomarkers predictive of DN in children with type I diabetes, before the appearance of a microalbuminuria.
