The childhood obesity is a global epidemic. Some studies with pre-pubertal children reported a positive relationship between fat mass and bone. However, there are no available data on the influence of the nutritional status on parameters of quantitative ultrasound (QUS). The aim of this study was to evaluate the influence of nutritional status in bone mass assessed by QUS of proximal phalanges in girls. The bone mass parameter, amplitude dependent speed sound (AD-SoS) in meter...

Background: It is known that one of the features of rheumatoid arthritis (RA) is a generalized bone loss, therefore important tasks for the physician are timely evaluating of the risk of fractures and approving osteoporosis treatment in patients with RA.Objectives: Through the Programme of the Russian Association of Rheumatology for the diagnosis, prevention and treatment osteoporosis (OP) in patients with RA we evaluated the 10 year probability of major...

Aim: We present the case of a 36y female patient with multiple fragility fractures after the age of 21 and mutations in COL1A1, COL1A2 and GNAS genes.Material and methods: A 36y female patient with multiple fractures of the axial and appendicular skeleton was referred to us for consultation. The patient was born with hexadactyly of the left foot and had a history of mild thoracolumbar scoliosis (10°) and medium height (165 cm) with no other history ...

Low fracture (FX) incidence has been demonstrated in women with postmenopausal osteoporosis (PMO) treated with DMAb for up to 10 years in the FREEDOM extension [Bone ASBMR 2015]. Bone biopsy-based assessment of DMAb’s effects at the tissue level has demonstrated a low remodelling rate consistent with DMAb’s mechanism of action (Reid JBMR 2010; Brown JBMR 2014). From FREEDOM, we report the effects of DMAb on bone matrix mineralization in women who un...

Introduction: Mitochondrial dysfunction is associated with several clinical outcomes including diabetes and myopathy and is implicated in the human aging process. We previously showed that the mitochondrial DNA point mutation mtDNA3243A>G is associated with lower BMD and altered bone structure. The aim of this study was to assess bone turnover markers in individuals with the mutation and controls.Methods: We recruited 45 patients (29 female, 16 male)...

STRUCTURE was a phase 3, open-label study evaluating the effect of romosozumab or TPTD for 12 months in women with postmenopausal osteoporosis transitioning from bisphosphonate therapy (NCT01796301). This study enrolled women with postmenopausal osteoporosis who had taken an oral bisphosphonate for ≥3 years prior to screening and alendronate in the year prior to screening; had a BMD T-score ≤−2.5 at the total hip (TH), lumbar spine (LS), or femoral neck (FN);...

Objectives: Bone development can be enhanced by exercise during growth, but not all types of exercise may be beneficial. Weight bearing and non-weight bearing sports have different effects on bone outcomes during adolescence. However, there is no longitudinal evidence comparing the effects of popular sports in the UK on bone acquisition in adolescent males.Methods: In the present study 116 adolescent males (13.1±0.1 years: 37 footballers, 37 swimmer...

Osteoporosis is a common skeletal disorder characterized by low bone mass leading to increased bone fragility and fracture susceptibility. Little is currently known about what specific factors stimulate osteoblast differentiation from human mesenchymal stem cells (hMSCs). Therefore, the aim for this project is to determine novel factors and mechanisms involved in human bone production which can be targeted to treat osteoporosis, using gene expression profiling and bioinformati...

Objectives: Osteopenia is a complication of childhood cancer treatment but it is unknown to which extend this occurs in adult survivors, and which subgroups are at risk. We examined bone mineral density (BMD) and assed the relative importance of potential determinants of low BMD in very long-term adult survivors of childhood cancer.Methods: The single-center cohort study included 410 adult CCSs (median age at diagnosis: 6.6 years (range: 0–17 years)...
