Arterial Wall Calcium Load in Pseudoxanthoma Elasticum (Ca-Art-PXE2)
Quantification and preferential sites of arterial wall calcification within the coronary and lower legs arteries will be comared between Pseudo-Xanthoma elasticum(PXE) atients and type 2 diabetics and Chronic Kidney disease.
Type 2 Diabetes

Patients with genetically and clincally proven PXE
chronic kidney disease
Type 2 diabetic patients with mediacalcosis and matched to PXE patients for gender and age (+/- 5 yrs).
patients with chronic kidney disease and matched to PXE patients for gender and age (+/- 5 yrs).
In a previous work we have observed that patients suffering from PXE, a soft-tissue calcifying inherited autosomal disease, exhibited specific structural and functionnal features within the peripheral arteries. We now want to quantify and determine the preferential sites of the arterial wall calcification (Agatston score) between these patients compared to diabetics and patients with chronic renal insufficiency with mediacalcosis.
All variables will be collected from a cohort of PXE monitored in our PXE Health and Care centre at the university hospital of Angers. Quantification of the arterial wall calcium load will be performed using helicoidal CT-scan. These variables will be compared to the same measurements performed in type 2 diabetic and chronic kidney disease patients paired by age and gender.
