Increased Bone Turnover Markers after Renal Transplantation

Bone remodeling is a process that occurs continuously in a seemingly inactive tissue like bone. Because of decreased vitamin D synthesis, phosphorus retention and decreased calcium blood concentration, patients with chronic renal failure (CRF) develop secondary hyperparathyroidism1–5. Elevated PTH levels shifts balance between osteoblast and osteoclast activity in favor of osteoclast activity and, therefore, bone resorption. Bone metabolic disorder that affects patients with CRF is called renal osteodystrophy (ROD)1–5. We presume that renal transplantation reverses bone metabolism disorder and our goal was to establish whether osteoblast and osteoclast activity returns to the levels of healthy individuals
