A correlation between bone mass density and body mass index and the lipid profile?

Radoi V. , Carsote M. , Virgolici B. , Poiana C.

Bone mass density and beta cross laps have been recognized as valid tests for the diagnostic and treatment control, as well as fracture prediction for osteoporotic patients. Statin treatment has been reported to be associated with a reduced risk fracture in these patients also.

Reference intervals for serum N-MID osteocalcin concentration measured with the IDS-iSYS automated system

Hannemann A. , Friedrich N. , Spielhagen C. , Rettig R. , Nauck M. , Wallaschofski H.

Background: Osteocalcin (OC) is a bone-specific protein produced primarily by osteoblasts during bone formation. The OC concentration is used to assess fracture risk and monitor treatment of osteoporosis and other disorders of bone metabolism. To adequately interpret the OC concentration, it is necessary to calculate reference ranges from a healthy reference population, adapted to a specific laboratory method.Methods: We established a healthy reference p...

Prevalence of morphometric vertebral fractures and bone quality measured by spinal deformity index in type 1 diabetic patients

Zhukouskaya V. , Eller-Vainicher C. , Vadzianava V. , Zhurava I. , Korolenko G. , Cairoli E. , Beck-Peccoz P. , Shepelkevich A. , Chiodini I.

Background and objectives: There are a lot of studies demonstrating low bone mineral density (BMD) and elevated fracture risk in patients with type 1 diabetes. But there are scarce data about the prevalence of morphometric vertebral fractures (MorfoFx) and spinal deformity index (SDI) that is considered as a surrogate marker of bone quality. Therefore, the objective of this study was to evaluate BMD, the prevalence of MorfoFx and bone quality by SDI in type 1 diabetics.<p ...

Successful treatment of thyrotoxicosis is accompanied by a decrease in serum sclerostin levels

Skowronska-Jozwiak E. , Krawczyk-Rusiecka K. , Lewandowski K. , Adamczewski Z. , Bienkiewicz M. , Lewinski A.

Sclerostin, a product of a SOST gene, is a protein expressed by osteocytes that inhibits osteoblastic bone formation. Several hormones including PTH and glucocorticosteroids and have been suggested as possible regulators of sclerostin production. The influence of thyroid hormones on sclerostin synthesis has not been investigated so far. The aim of the study was to evaluate sclerostin concentrations in patients before and after treatment of thyrotoxicosis.<p class="abstext"...

Investigating recurrent hypophostaemia

Agha-Jaffar R. , Reddy M. , Bassett D. , Cox J.

Oncogenic osteomalacia is a rare paraneoplastic phenomenon characterised by abnormal phosphate metabolism typically caused by discrete benign tumours. Due to the indolent presentation and slow progression, diagnosis is often delayed and localisation of the tumour can prove difficult. We present the case of a 64-years-old gentleman who was investigated by the endocrinology department for hypophosphataemia. Three years prior to this, he had started to experience exertional fatig...

Ovariectomy modulates the effect of phytoestrogens on creatine kinase specific activity in skeletal organs in female rats

Somjen D. , Gayer B. , Kohen F. , Posner G. , Kaye A.

Ovariectomy of immature female rats, results in significant decreased parameters in different organs. Previously we found that estradiol-17b (E2) restored these parameters in the different organs of ovariectomized female rats (Ovx) to values obtained in intact immature female rats. E2 also stimulated creatine kinase specific activity (CK) a hormonal-responsive marker in organs containing estrogen receptors. In the present study, we compared the effects of...

Adiponectin and bone mineral density in obese postmenopausal women

Milin J. , Micic D. , Stamenkovic-Pejkovic D. , Jeremic D. , Kendereski A. , Zoric S. , Cvijovic G. , Sumarac-Dumanovic M.

Introduction: Adiponectin and its receptors are expressed in human osteoblasts, suggesting that adiponectin may be a hormone linking bone and fat metabolism. In contrast to adiponectin anabolic effect on bone in vitro studies, clinical and animal studies suggest that adiponectin may have negative effects on bone by stimulating the receptor activator of nuclear factor-κB ligand (RANKL) pathway and inhibiting the production of the decoy receptor for RANKL and osteopr...

Cimetidine (histamine H2-receptor antagonist and antiandrogenic drug) exerts a beneficial effect in the injured tissues by periodontal disease in male rat molars

Longhini R. , de Oliveira P. , Sasso-Cerri E. , Cerri P.

Studies have demonstrated the presence of androgen receptors in osteoblasts and osteocytes, confirming that androgens are important for the maintenance of bone in men. Additionally to steroid hormones, histamine stimulates osteoclast differentiation and survival and plays a role in the inflammatory response via H2 receptors. We purposed to investigate whether cimetidine, an histamine H2 receptors antagonist and antiandrogenic drug, interferes in the periodontal tissue damages ...

In 100 consecutive osteoporotic women referred to our clinic we assessed 25OHD3 and PTH levels. Patients suffered from postmenopausal osteoporosis and intolerance of oral bisphosphonates, were treated at least for 6 months with calcium and vitamin D. The reasons of intolerance of oral medication were gastritis (53), esophagitis (18) or peptic ulcer (29 cases). Patients were therefore chronically treated with proton pump inhibitors (PPI).
