Introduction: The best repletion and maintenance dosing regimens with cholecalciferol in vitamin D deficient HIV-1 patients remain unknown. Protease inhibitors (PIs) have been shown to inhibit vitamin D 1α- and 25α-hydroxylation in hepatocyte and monocyte cultures. We therefore evaluated the effect of a single high dose of cholecalciferol in vitamin D deficient HIV-1 postmenopausal women undergoing treatment with highly Active Anti-Retroviral Therapy (cART), with and...

Introduction: Risk of vertebral fracture (VFx) is in part independent of bone mineral density (BMD) in primary hyperparathyroidism (PHPT). The aim of this study was to examine whether other factors, including the genotype of common polymorphisms in the calcium-sensing receptor (CASR) gene, are associated with VFx.Patients and methods: In 266 Caucasian PHPT patients, serum calcium, phosphate, creatinine, total alkaline phosphatase, intact PTH, 25-hydroxyv...

The aim of the present study was to evaluate the phenotype of PHPT, the adherence to International Guidelines and the rate of surgical cure of PHPT in Italy. From January 2014–January 2016, we conducted a prospective, multicenter (n=29 endocrine tertiary referral centers) study on patients with PHPT, recording clinical and biochemical data, parathyroid imaging and therapy choice at baseline and at last follow-up. The study group included 604 patients with PHPT, w...
