Ankylosing spondylitis is a chronic inflammatory rheumatic disease, characterized by axial pain and osteoproliferation, leading to painful rigidity of the spine and disability. In contrast with this bone formation, bone loss is an early event in this disease, and an increased vertebral fracture risk (but not non-vertebral fracture risk) has been reported in these patients.Prospective studies have shown that potent anti-inflammatory drugs, such as anti-TN...

: In osteoporosis, poor adherence to bisphosphonate (BP) therapy is common, and is associated with poor outcomes and increased treatment costs (Siris 2006; Recker 2005). Although compliance is improved with monthly vs weekly dosing (Reginster 2008), no evidence suggests cycling through BP agents offers therapeutic benefit, assessed by bone mineral density (BMD). In two randomized, open-label studies in postmenopausal women aged ≥55 years previously treated with, but subo...

Denosumab treatment is associated with low fracture incidence, sustained BMD increases, and reduced sCTX. The decrease in median sCTX is at the quantifiable limit (0.049 ng/ml) one month post-dose, remains low, and attenuates at the end of the 6-month dosing interval. Using 7 years of data from the FREEDOM study and its extension, we characterized changes in sCTX over time and the influencing factors. In the bone turnover marker and pharmacokinetic substudies, serum was collec...

Roux-en-Y gastric bypass surgery (RYGBP) is one of the leading surgical treatments for morbid obesity and leads to significant long-term weight loss, diabetes remission, decreased cardiovascular events, and reduced mortality. RYGBP is, however, also implicated in increased fracture risk, mainly due to higher bone turnover rates and malabsorption. In the present study we used Raman microspectroscopic analysis to determine bone quality (an important determinant of bone strength)...

Low bone mineral density (BMD) is an important and modifiable risk factor for fracture in postmenopausal women with osteoporosis. Denosumab (DMAb) shows a stronger relationship between BMD increases and antifracture efficacy than oral bisphosphonate (BP) therapies. Subjects who remain at higher risk of fracture despite current BP therapy need treatment. In two studies, DMAb significantly increased BMD and decreased bone turnover markers vs a BP (ibandronate (IBN) or risedronat...

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...

Celiac disease (CD) is a frequent cause of malabsortion in childhood and affects calcium and vitamin D absorption.Aim: Analyze the vitamin D levels and bone mineral density (BMD) at diagnosis in patients affected with CD, and the influence of the age of diagnosis in the clinical presentation.Patient: 52 patients (female: 26) were evaluated.Results: The percentage with vitamin D deficiency (<20 ng/ml) was ...

Molecules secreted by the osteoclast or ‘clastokynes’ are essential to stimulate bone formation by osteoblasts. Treatments with bisphosphates and Denosumab target osteoclast survival and differentiation. This suppresses bone turnover and is suspected to increase the risk of atypical fractures in the long term. A solution to overcome this is to develop strategies that target selectively the activity of osteoclasts without affecting their survival or differentiation. S...

Beside the bone mass, structural changes are important determinants of the bone strength. Patients with osteoarthritis (OA) seem protected against femoral neck (FN) fracture. When compared to osteoporosis, FN in OA are characterized by a higher bone mass and a better trabecular microarchitecture (Blain et al., 2008, Boutroy et al., 2011). The presence of microcracks is one of the determinants of the bone strength. The aim of this study was to evaluate the mic...
