Study Evaluating Denosumab on Bone and Vascular Metabolism in Osteoporotic Chronic Kidney Disease

Aim of this study is to evaluate in a population of old osteoporotic chronic kidney disease females the effect of denosumab: * on bone mineral density (femoral T-score) (by bone densitometry) at 24 months * on bone mineral density evolution (femoral T-score) (by bone densitometry) after 24 months of follow-up * on bone mineral density evolution (lumbar T-score) (by bone densitometry) after 24 months of follow-up * on coronary and abdominal aorta calcification scores evolution (by multiple detector computed tomography and plain abdominal X-ray) after 24 months of follow-up * on parameters of bone remodelling (OPG, RANKL, sclerostin, DKK-1), of mineral and calcium metabolism (FGF23 Ct, Klotho, PTH, 25(OH) vitamin D3, phosphorus, calcium, bone alklaline phosphatase, osteocalcin, CTX), of inflammation (CRP) after 24 months of follow-up * on cardiovascular morbidity (cardiovascular events) and mortality after 24 months of follow-up * the tolerance after 24 months of follow-up
