The ‘canonical’ Wnt/β-catenin pathway plays an important role in the development and patterning of bone. Dkk1 (Dickkopf1) and sclerostin are competitive soluble inhibitors of this pathway. Serum sclerostin is decreased in patients with primary hyperparathyroidism (PHPT) compared to the healthy subjects and hypoparathyroid (HypoPT) patients. No data are currently available on Dkk1 serum level in PHPT.We evaluated serum Dkk1 and sclerostin l...

Primary hyperparathyroidism (PHPT) is defined by hypercalcemia and high PTH levels. In recent years a variant of PHPT has been described, namely normocalcemic PHPT (NPHPT), which is characterized by normal serum calcium and high PTH levels, in the absence of other causes of secondary hyperparathyroidism. The epidemiology of NPHPT is poorly understood. We performed a survey in the early fall in a small Southern Italian village, in which all adult residents (n=1811) wer...
