Brief Summary:

Bone disorder is a significant problem in chronic kidney disease (CKD), becoming almost universal in stage 5 CKD patients. Besides the healthcare costs, bone disorder is associated with life-threatening complications, including fractures and cardiovascular (CV) events. Kidney transplantation provides circa 68% decrease in mortality and improves co-morbidity. Still, bone disease persists after transplantation.

The investigators hypothesize that bone-derived hormones can induce CV events in kidney transplanted patients. Therefore, early evaluation of the bone health is recommended, and prevention of its complications is required. Bone biopsy, an invasive and expensive method, is the gold standard for bone disorders diagnosis. Therefore, non-invasive predictors for bone disease are necessary. Classical biochemical markers of bone formation and resorption have shown a low sensitivity and low specificity. New markers, as fibroblast growth factor 23 (FGF23), and its cofactor klotho, and sclerostin are promising new markers for predicting CKD-associated bone and CV disease after transplantation.

This study assesses the phenotype of bone disease after transplantation (given by bone histology) and its correlation with serum FGF23, klotho and sclerostin, in order to evaluate its performance predicting CKD-associated bone and CV disease.
