Teriparatide (TPTD – recombinant human parathyroid hormone 1–34) markedly increases bone mineral density (BMD) and reduces fracture risk. Sequential treatment with an antiresorptive agent is believed to preserve or further increase BMD. Strontium ranelate (SR) is thought to uncouple bone remodeling resulting in increased BMD and reduced fracture risk. In this prospective study, we aimed to evaluate the effect of SR on BMD in women with established osteoporosis previo...

Introduction: There is indirect evidence of unfavorable effects of parathyroid hormone (PTH) on glucose metabolism. Teriparatide (recombinant human PTH 1-34 - TPTD) has been recently available for the treatment of osteoporosis.Aim: To evaluate the acute and chronic effect of TPTD on blood glucose and insulin levels in women with established osteoporosis.Patients and methods: Twenty-three postmenopausal women with established osteop...

Introduction: Adipokines and ghrelin exert well-documented effects on energy expenditure and glucose metabolism. Experimental data also support a role in bone metabolism, although data from clinical studies are conflicting. The purpose of this cross-sectional study was to investigate the association of serum concentrations of leptin, adiponectin and ghrelin with bone mineral density (BMD) in post-menopausal women.Methods/design: BMD in lumbar spine and f...

Although vaspin is regarded an insulin-sensitizing adipokine, its role in gestational diabetes mellitus (GDM) is currently unknown. We aimed to evaluate serum vaspin levels and their correlation with insulin resistance in women with and without GDM. Forty-four women with GDM (GDM Group 20 managed with diet only (GDM-diet) and 24 with diet plus insulin (GDM-insulin)) and 44 age-matched pregnant women with normal glucose tolerance (control group) were studied. Serum glucose, lip...

Background: Epigenetic changes appear to be implicated in the development of parathyroid tumors. In this study we investigated the microRNA expression profile in the serum and tissue samples from patients with primary hyperparathyroidism (PHP) due to sporadic parathyroid adenomas (SPAs).Methods: Our study cohort consisted of 40 patients with PHP due to SPAs that underwent parathyroidectomy (PTX).MicroRNA extraction was performed fr...

Purpose: High serum homocysteine (HCY) and indirectly deficiency of folate and/or vitamin B12 stimulate bone resorption and adversely affect collagen cross-linking. The aim of this study was the evaluation of serum levels of HCY, folate and vitamin B12 in patients with Paget’s disease of bone (PDB) and the effect of zoledronic acid (ZOL) on their serum levels.Methods: This was a prospective open-label cohort study, with a control arm at baseline. Ni...
