简要总结
The investigator aim to identify the role of inorganic pyrophosphate and other anti-calcifying molecules in vascular disease in children with chronic kidney disease, with a view to developing therapeutic approaches aimed at limiting the onset of vasculopathy.
详细描述
The study of pro- and anti-calcifying molecules in children with chronic kidney disease will be carried out using dosages made on serum in comparison with the dosage of these same molecules in control children matched according to age and sex. without chronic kidney disease. An evaluation of vascular function by clinical (auscultation, palpation) and ultrasound techniques (measurement of intima-media thickness and measurement of pulse wave velocity) will also be carried out in children with chronic kidney disease and compared to norms of children without chronic kidney disease. These evaluations aim to improve understanding of the pathophysiology of vascular calcification and thus open up therapeutic perspectives in these children.

结局指标
主要结局
Plasma pyrophosphate concentration [PPi]pl in children with CKD
时间窗: 18 months
Compare plasma pyrophosphate concentration \[PPi\]pl between children with CKD (dialysis group and non-dialysis, non-transplant group) and \[PPi\]pl of children with normal renal function. Plasma PPi concentration during fasting sampling; (μmol/L) by a proprietary assay developed at LP2M. We will match the 3 MRC groups with their respective control groups according to age, sex and pubertal stage.
次要结局
- Markers of vascular damage in CKD(18 months)
- Markers of phosphocalcic metabolism(18 months)
- Plasma pyrophosphate [PPi]pl concentration in children with renal transplantation(18 months)
- Urinary PPi concentration(18 months)
