Background: Vitamin D status is associated with bone health. Vitamin D deficiency leads to decreased bone formation and increased bone resorption. 25-hydroxyvitamin D (25(OH) D), parathyroid hormone (PTH) levels in children could affect bone turnover, and in turn, the bone markers should reflect vitamin D condition. In children the relationships among 25(OH) D, PTH and bone turnover markers are remain.Objective: To explore the associations among serum 25...

Patients with improved health understanding have greater autonomy over, and motivation towards, health-related lifestyles. We compared self-perceived fracture risk and 3-year incident fracture rates in postmenopausal women for a range of co-morbid diseases using data from the Global Longitudinal study of Osteoporosis in Women (GLOW).GLOW is an international cohort study involving 723 physician practices across 10 countries in Europe, North America, Austr...

Introduction: The availability of bone turnover markers (BTMs) that are kidney independent has facilitated the monitoring of bone turnover in renal patients with hyperparathyroid bone disease. The effects of Cinacalcet on BTMs and on the relationship between parathyroid hormone (PTH) and BTMs were studied.Methods: The formation marker procollagen type 1 N propeptide (P1NP) and resorption marker tartrate resistant acid phosphatase 5b (TRACP5b) were measur...

Background: Osteoporosis is a leading cause of morbidity in patients affected by β-thalassaemia major (TM) and intermediate thalassaemia (TI). Appropriate supportive care and identification of long-term sequels of therapy are important in thalassaemic patients. As low bone mineral quality (BMQ) in patients can be considered a marker of possible degeneration to osteopenia and osteoporosis in adulthood, we evaluated bone features in a young population followed at ‘A. P...

Introduction: Serum 25(OH)D concentrations for optimal bone metabolism in children is unknown. Only few data exist describing the effects of increasing serum 25(OH)D on bone metabolism markers.Aim: The aim of the study was to explore the association between serum 25(OH)D and bone metabolism markers in children.Patients and methods: Serum levels of bone formation (OC, P1NP) and bone resorption (CTx) markers (Cobas e411, Roche Diagno...

The literature has suggested that bone mineral content is modulated by muscle mass and activity. We investigated the relationship between DXA assessed total body bone mineral content, total body lean mass, appendicular lean mass and obesity (a possible marker of inactivity) in a population of 73 boys between the age of 7 and 19 using a Norland XR-46 system.Regression analysis shows that in these growing boys there is a strong positive relationship betwee...

Introduction: The purpose of this study was to determine osteoporosis (OP) and osteopenia in patients with various rheumatic diseases depending on the duration of use glucocorticosteroids (GCS) and daily dose of GCS.Methods: The study included 125 patients (90 women and 25 men) with various rheumatic diseases receiving GCS therapy. BMD was measured by DXA (Hologic). Patients were divided into two groups. Group I included postmenopausal women and men over...

Subject: To examine the relationship between calcification of the coronary arteries, coronary atherosclerosis and indicators of bone mineral density (BMD) among males with coronary heart disease (CHD).Materials and methods: Seventy-four males with documented CHD were examined. BMD was assessed by dual energy absorptiometry with T-criterion definition of the proximal femur and lumbar spine, coronarography, multispiral computed tomography with quantificati...

Introduction: To compare serum vitamin D levels in elderly patients with or without osteoporotic spinal compression fractures (OSCF) and to evaluate a correlation between serum vitamin D level and several variables such as age, and bone mineral density (BMD), bone turnover markers.Methods: The medical records of 78 patients with OSCF (fracture group) and 84 age-matched control patients who were diagnosed osteoporosis without OSCF (control group) were rev...

Introduction and aims: Vitamin D deficiency is a prevalent disorder in developing countries. Clinical manifestations of the deficiency include musculoskeletal disorders, such as nonspecific muscle pain, poor muscle strength and low bone mineral density (BMD). The aim of this study was to determine the prevalence of vitamin D deficiency and low BMD in healthy Saudi women.Methods: The subjects of this cross-sectional study comprised 449 healthy Saudi women...
