Growth hormone deficiency leads to reduced bone turnover, mainly due to alterations in PTH circadian rhythmicity as well as to a lack of sensitivity of the kidney and bone to the effects of PTH. These mechanisms may be responsible for bone turnover changes and development of osteoporosis. Patients with GHD show abnormalities of renal phosphate metabolism, which may also contribute to the pathogenesis of bone loss in these patients. GH treatment leads to restoration of renal tu...

Bone metabolism can be measured indirectly with specific biochemical markers. Desoxypyridinolin (DPD) is a derivate of hydroxypyridinium, which is discharged by bone resorption and is totally excreted urinary. A further marker of collagen resorption is the c-terminal telopeptide of collagen type I, which is liberated to blood circulation within the bone’s degradation and undergoes renal elimination. The aim of our investigation was to look after a correlation of these par...
