Objectives: X-linked hypophosphataemia (XLH) is a rare inherited form of osteomalacia characterised by low blood phosphate levels which lead to inadequate mineralisation of bone resulting in rickets, skeletal abnormalities, physical impairment, weakness, and pain. Burosumab is an anti-FGF23 fully human monoclonal-antibody, and the first treatment to target the underlying pathophysiology of XLH. Real-world evidence is important in validating the findings of clinical studies. We...

Objectives: Cross-sectional studies show that exercise may have positive effects on bone outcomes in youth. However, there is no evidence from longitudinal studies, which type of sports can induce improvements in bone acquisition in adolescent athletes. Therefore, this study aimed to investigate the longitudinal differences in bone acquisition and bone metabolism between adolescent males participating in osteogenic (football) and non-osteogenic (swimming, cycling) sports compa...

Over the past decade, many GWAs and meta-analyses were performed to identify genes and regions involved in bone metabolism and in the osteoporotic phenotypes. Nevertheless, the majority of these GWAS results were not tested at any functional level. This study aims to find and study functional regions in the RANK and RANKL genes that encode well-established proteins in the bone remodeling equilibrium. SNPs, chosen for their location in an evolutionary conserve...

Objectives: To assess safety and clinical efficacy during 1–34 parathyroid hormone treatment (1–34-PTH) in real clinical practice; to describe fracture outcome after 1–34-PTH discontinuation in real clinical practice.Methods: We performed an observational study in real clinical practice of all consecutive severe osteoporosis (sOP) patients referred to our Rheumatology Department from Feb’10 until Jan’14. All patients were referre...

Background: Oral glucocorticoids (GC; prednisolone dose of 0.75 mg/kg per day), help to preserve muscle strength and prolong independent walking in boys with DMD. This study compared longitudinal growth, body mass index (BMI), bone mineral density (BMD), vertebral fractures (VFs) and ambulatory status in boys with DMD on daily (DAILY) or intermittent (INTER; 10 days on & 10 days off), oral GC regimens.Methods: 50 DMD boys from two UK centres were inc...

Objective: Describe UK regional variation in prescription of anti-osteoporosis drug therapy before and after a primary hip fracture during 1999–2013.Materials and Methods: We used primary care data (Clinical Practice Research Datalink) to identify patients with a hip fracture and primary-care prescriptions of any anti-osteoporosis drugs (bisphosphonates, strontium, denosumab, oestrogen therapy, SERMS, teriparatide) prior to primary hip fracture and ...

Background: Surgical treatment of type 2 diabetes, specially in obese patients, has provided good results in the control of blood glucose and Hb1Ac although its effect on bone health is not clear. The aim of this study was to evaluate gene expression of bone remodelling markers in type 2 diabetic Goto-Kakizaki (GK) non-obese rats after gastrojejunal bypass and sleeve gastroplasty, and their relationship with hormonal parameters.Materials and methods: We ...

Objective: Several reports suggest very low persistence with oral bisphosphonates, but there is a scarcity of data on persistence with other anti-osteoporosis medications. We therefore compared rates of early discontinuation (in the first year of therapy) between all available outpatient anti-osteoporosis drugs in Catalonia, Spain.Study design: population-based retrospective cohort study.Participants and source of data: The data in...
