Patients with chronic hypoparathyroidism (HypoPT) treated with oral calcium and active vitamin D metabolites are at risk of renal complications, because of the lack of action of PTH at the renal tubule. In the present study we evaluated 90 patients (68 females and 22 males; age: 51.8±14.1 yrs) with chronic postoperative Hypo (PO-HypoPT) diagnosed since at least 3 years. All patients were treated with calcitriol and 35 (39%) with oral calcium two patients were also treated...

Primary hyperparathyroidism (PHPT) is a common disorder in adults but is uncommon in young people and features of juvenile PHPT (J-PHPT) are debated in literature. The aim of the study was to evaluate the characteristics of PHPT in juvenile sporadic (S) and familial (F) patients. It’s a monocentric prospective study at a referral centre in 154 patients with ≤40 years. Patients were evaluated at diagnosis and at the last follow-up visit (median follow-up 2 years), co...

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...

Primary hyperparathyroidism (PHPT) is usually a sporadic disorder, but in <10% of cases occurs as part of hereditary syndromes, including multiple endocrine neoplasia types 1 and 2A (MEN1 and MEN2A), hyperparathyroidism-jaw tumor syndrome (HPT-JT) and familial isolated hyperparathyroidism (FIHP).MEN 1 is an autosomal dominant disorder characterized by tumours in multiple endocrine glands, most commonly parathyroid, enteropancreatic and anterior pitui...
