Longitudinal assessment of spinal bone mineral density in children with neurofibromatosis type 1 using dual energy absorptiometry and quantitative computed tomography

Eelloo Judith , Ward Kate , Huson Susan M , Adams Judith E , Russell Sarah , Wright Naville , Evans Gareth , Mughal M Zulf

Aim: Scoliosis is a common skeletal problem affecting 10–30% of patients with neurofibromatosis type 1 (NF1). NF1 patients have been shown to have reduced bone mineral density (BMD) which may play a role in the pathogenesis or progression of scoliosis. Our centre is one of four international centres currently evaluating the efficacy of various spinal imaging techniques and BMD as predictors for scoliosis in NF1. In our cohort we measured the lumbar spine (LS) BMD both by ...

Gout is associated with an excess risk of osteoporotic fracture: findings from a Danish registry

Dennison Elaine , Rubin Katrine H , Harvey Nick , Walker-Bone Karen E , Schwarz Peter , Cooper Cyrus , Abrahamsen Bo

Objective: Although metabolic syndrome is common in gout patients, recent reports that bone mineral density may actually be reduced (and falls common) in this group have led researchers to hypothesise that osteoporotic fracture may be more common in subjects with gout than in healthy controls. We tested this hypothesis in a national Danish registry.Material and Methods: We identified subjects as new users of allopurinol, a proxy for gout, for the years 1...

Bisphosphonates for osteoporosis and risk of breast cancer: misleading results from observational studies

Cummings Steven R , Hue Trisha , Cauley Jane A , Bauer Doug C , Ensrud Kristine E , Barrett-Connor Elizabeth , Black Dennis M

Purpose: To test whether bisphosphonates for osteoporosis reduce the risk of breast cancer.Background: Observational studies and meta-analyses find that women taking bisphosphonates have about a 1/3rd reduction in risk of breast cancer as soon as 1 year of treatment. This is plausible because bisphosphonates have in vitro anti-tumor activity and high doses of zoledronate reduce recurrence in women with breast cancer. However, observational studi...

The relationship between muscle strength and bone outcomes in ageing UK men

Zengin Ayse , Pye Stephen R , Cook Michael J , Adams Judith E , Wu Frederick C W , O'Neill Terrence W , Ward Kate A

Morbidity and mortality are associated with osteoporosis and sarcopenia. There are few data describing the associations between functional measures of muscle and bone. Therefore, the aim of this study was to examine the associations of muscle strength and tibial bone outcomes in ageing men.Men (n=301) aged 40–85 years were recruited in UK (201-White, 43-Black, 57-South-Asian). pQCT was performed at the 38 and 66% tibia with the outcome meas...

Growth, bone and muscle mass are adversely affected in bone marrow transplant recipients: a body composition analysis

Doulgeraki Artemis , Vlachopapadopoulou E , Peristeri I , Paisiou A , Polizois G , Kaisari K , Monopolis I , Vessalas G , Michalacos S , Kitra V

Objectives: There are many factors leading to poor bone health and imbalanced body composition in bone marrow transplant (BMT) recipients. We aimed to report our patients’ profile and to correlate it with clinical parameters.Methods: Cross-sectional study of paediatric BMT patients. Assessment of growth (height, weight, BMI) and dual-energy X-ray absorptiometry (DXA) for evaluation of bone mineral density (BMD) and geometry, muscle and fat mass. All...

Superior Gains in Bone Mineral Density (BMD) and Estimated Strength at the Hip for Romosozumab Compared With Teriparatide (TPTD) in Women With Postmenopausal Osteoporosis Transitioning From Bisphosphonate Therapy: Results of the Phase 3 Open-label STRUCTURE Study

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);...

WNT1 mutations in early-onset osteoporosis and osteogenesis imperfecta identify a key WNT ligand regulating bone mass

The role of the WNT pathway in skeletal maintenance has been extensively studied since the identification of mutations in key signaling WNT mediators (LRP5 and sclerostin) in high and low bone mass phenotypes. However, the identity of the key WNT ligand that signals via LRP5/6 has remained unknown. We aimed to identify genes with a major effect on the skeleton by studying individuals and families with early-onset osteoporosis or osteogenesis imperfecta (OI).<p class="abste...

Bone quality in severe adolescent idiopathic scoliosis -- quantitative computed tomography of lumbar spine vs high-resolution peripheral quantitative computed tomography of the distal radius: a pilot study

Introduction and objective: Adolescent idiopathic scoliosis (AIS) is a structural spinal deformity characterized by 3D deformity with lateral curvature of ≧10° as measured by Cobb angle and is predominately seen in girlsaged between 10 and 16-years-old. Low bone mass has been found to be a significant prognostic factor for curve progression in AIS.In our hospital, computed assisted navigation is used for intraoperative pedicle screw placement...

Burosumab experience in UK X-linked hypophosphataemia children under five years old

Dharmaraj Poonam , Burren Christine , Cheung Moira S , Padidela Raja , Mughal Zulf , Shaw Nick , Saraff Vrinda , Nadar Ruchi , Randell Tabitha , Mushtaq Talat , Ramakrishnan Renuka , Sennipathan Senthil , Sakka Sophia , Bath Louise , Elleri Daniela , Davies Justin H , Barton John , Tucker Ian , Rayner Lauren , Arundel Paul , Gilbey-Cross Robyn , Tothill Alexander M , Philip James , Sawoky Nadine , Connor Paul , Mathieson Leigh

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 and rickets. 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 report relevant real-world biochemical data on children under five years ...

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...
