About

To be able to evaluate the predictive value of glycosylated ferritin as a predictive marker of hepatic iron stock in dialysis patients, we need to validate these results with a cohort of healthy volunteers.

Full description

This biological collection will include a sample of 2 dry tubes and 2 EDTA tubes. A haematological assessment (CBC, platelets, reticulocytes, Chr (hemoglobin content of reticulocytes), TP-INR, AST, ALT, GGT), measurement of biological markers of iron metabolism (ferritin, serum iron, CRP, transferrin, soluble receptors transferrin, transferrin saturation coefficient) as well as a creatinine assay to validate the normality of renal function in healthy volunteers (GFR established from the MDRD formula), a complete ionogram and a phosphocalcic balance being given the interactions in the dialysis patient (but also in normal subjects) between iron metabolism and phosphocalcic metabolism (calcemia, phosphoremia, PTH, 25OHD3, 1,25OH2D3) will be performed.

We will also study the links between iron overload in dialysis patients and the modulation of the synthesis of parathyroid hormone (intact PTH), FGF23, alpha Klotho and sclerostin.
