Secondary hyperparathyroidism is defined as autonomic secretion of parathormon (PTH) whose 1-84 fraction level is up to 60 ng/l. | |||||||||||||||

|
The reduction in intestinal calcium absorption associated with low levels of vitamin D triggers the release of parathyroid hormone (PTH), which stimulates the absorption of calcium through augmentation of the production of 1,25(OH)2D [2, 3]. | |||||||||||||||

In mild vitamin D deficiency, the elevation of serum PTH increases the conversion of 25(OH)D to 1,25(OH)D to compensate for the insufficient 25(OH)D available; however, elevation in PTH increases bone resorption, leading to additional bone loss [19]. | |||||||||||||||

|
These recommendations are based on the amount of vitamin D that is needed to maximally suppress PTH (184) secretion [22], but there is no consensus, as some investigators advocate that the 25(OH)2D level needed to maximally suppress PTH is 30 to 44 ng/mL [23]. | |||||||||||||||

A number of factors influence the renal tubular reabsorption of Pi, such as dietary phosphorus content, and parathyroid hormone (PTH), growth hormone (insulin-like growth factor 1) and thyroid hormone concentrations, although these latter two hormones probably do not play a major role in the short-term control of serum Pi concentrations, but, rather, determine long-term concentrations. | |||||||||||||||

Currently osteoporosis is viewed as a heterogeneous condition which can occur in any age of life and its etiology is attributed to various endocrine, metabolic and mechanical factors (abnormalities of parathyroid hormone and calcitonin secretion, insufficient vitamin D and calcium intake, postmenopausal hormonal condition, pregnancy, nutritional disorders, immobility and consumption of drugs such as cortisone, among others) [2]. | |||||||||||||||

Loss-of-function mutations in CASR impair the feedback inhibition of parathyroid hormone secretion in response to a rise in the blood calcium concentration. | |||||||||||||||
