To decline screening for osteoporosis: a study on individual decision making, meaning and reasons for non-participation

Rothmann Mette , Huniche Lotte , Ammentorp Jette , Brakmann Reinhard , Gluer Claus C , Hermann Anne Pernille

Purpose: This combined qualitative and quantitative study aimed to investigate women’s personal reasons for and choices to decline the screening for osteoporosis. The ROSE study is a randomized prospective population-based trial investigating the efficacy of a screening program to prevent fractures in women aged 65–80 years.Methods: A triangulated approach combining data from interviews and questionnaire. 7020 questionnaires from the screening ...

Cytokine levels in the bone marrow are not just a reflection of the levels in serum: suggesting that bone marrow constitutes an independent compartment

Harslof Torben , Sorensen Lotte , Pedersen Steen , Langdahl Bente

Bone marrow is composed of cells developed within the marrow compartment as well as blood supplied from the general circulation. Bone tissue is affected by cytokines within the bone marrow.We investigated if the levels of different bone acting cytokines differ between bone marrow and blood from the peripheral circulation.Fifty-three healthy postmenopausal women participated in a study designed to evaluate the effect of rosiglitazon...

A polymorphism in the TGF-β1 gene affects TGF-β1 secretion

Husted Lise , Sorensen Lotte , Stenkjaer Liselotte , Langdahl Bente

Transforming growth factor (TGF)-β1 is the most abundant growth factor in human bone. Several polymorphisms have been described in the TGF-β1 gene (TGFB1). We have previously shown that individuals with the CC genotype of the T29C polymorphism have higher bone mass at the femoral neck. The T29C polymorphism causes a change from leucine to proline at codon 10, which is located in the hydrophobic α-helical part of the signal peptide....

Bone-muscle unit assessment with pQCT in children with inflammatory bowel disease following treatment with Infliximab

Altowati Mabrouka , Malik S , Shepherd S , P McGrogan , RK Russell , SF Ahmed , SC Wong

Objective: To evaluate bone and muscle mass in children with inflammatory bowel disease (IBD) following infliximab (IFX) therapy.Methods: Prospective longitudinal study of 19 children (12 males), 17 crohn’s disease (CD), 1 ulcerative colitis (UC), 1 IBD unclassified (IBDU) of bone evaluation commencing treatment with IFX. Bone and muscle parameters were measured by pQCT at the non-dominant distal radius at 4 and 66% at baseline and 6 months. pQCT pa...

The impact of intravenous bisphosphonate on vertebral morphometry in children with secondary osteoporosis and vertebral fractures

Timmons JG , Morrice R , Joseph S , Shepherd S , Mason A , Ahmed SF , Wong SC

Background: Intravenous (IV) bisphosphonate (BP) is used for treatment of painful vertebral fractures (VF) in children with underlying chronic conditions. BP effect on vertebral height reshaping in this population is however poorly studied.Aims/Objectives: To evaluate the impact of IV BP on vertebral morphometry in children with VF and underlying chronic medical conditions with associated glucocorticoid (GC) therapy.Methods: Retros...

Persistence of musculoskeletal abnormalities in children and adolescents with inflammatory bowel disease: a prospective longitudinal study

S McCarrison , Mason A , SC Wong , Shepherd S , P McGrogan , Russell R , SF Ahmed

Objectives: To evaluate musculoskeletal development using pQCT and DXA in childhood onset inflammatory bowel disease (IBD).Methods: Prospective longitudinal study with 12 months follow-up in 43 children (23 males) with IBD: 30 crohn’s disease(CD), 13 ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU). pQCT at 4% and 66% radius, DXA for total body (TB), lumbar spine (LS) bone mineral content were assessed at baseline and 12 mo...

Enhancement of bone ultra structure preservation using high-pressure freezing and microwave-assisted fixation

Daghma Diaa Eldin S. , Heiss Christian , Khassawna Thaqif El

Despite the improvement in bone’s molecular, metabolic and live-cell imaging, histological investigation remains most crucial in bone biology for diagnostic and research purposes. Therefore, fixation of bone samples – especially for electron microscopy investigation – is critical to the ultrastructural analysis. Up to date, chemical fixation of bone tissue is performed at room temperature resulting in a compromised ultrastructure of bone sample. In this study, w...

Prevalence of vitamin D deficiency in adolescent Muslim girls attending a school in the UK, which adheres to a conservative dress code

Lukman S , Syahanee R , Berry J L , Mughal M Z

Aim: To determine the prevalence of vitamin D deficiency among adolescent Muslim girls attending a school in the UK, which adheres to a conservative dress code.Methods: Fifty-six (31%) out of 180 girls attending a Muslim High School for Girls (median age 13.2years, (IQR 12.5–13.8 years)) took part in this cross-sectional study. Seventy-nine percent (n=45) were of South Asian origin, 3.5% were Black African origin (n=2), 1.8% was Mi...

Relationship between total hip (TH) BMD T-score and incidence of nonvertebral fracture (NVFX) with up to 10 years of Denosumab (Dmab) treatment

Ferrari S , Adami S , Brown J P , Cosman F , Czerwiński E , de Gregorio L H , Malouf J , Reginster J-Y , Daizadeh N S , Wang A , Wagman R B , Lewiecki E M

The relationship between BMD T-score and FX risk has not been established in patients receiving osteoporosis therapy. In the FREEDOM Extension study, continuous DMAb therapy for up to 10 years increased BMD levels with no therapeutic plateau at lumbar spine or TH [Bone et al, ASBMR 2015]. Such improvements would only be meaningful if associated with FX reductions. We investigated the relationship between TH BMD T-score and NVFX in women who received DMAb during FREEDOM and tho...

Long term treatment with odanacatib maintains normal trabecular biomechanical properties in ovariectomized adult monkeys as demonstrated by micro-CT based finite element analysis of the vertebral cores

Cabal Antonio , Jayakar Richa Y , Zhang Jingru , Sardesai Swanand , Williams Donald S , Duong Le T

The cathepsin K inhibitor odanacatib (ODN) is a bone formation-sparing inhibitor of osteoclastic resorption activity. This drug is currently under development for the treatment of postmenopausal osteoporosis. To support the bone safety profile of ODN, we evaluated the effects of ODN on trabecular bone hard tissue properties in the estrogen-deficient model of the ovariectomized (OVX) rhesus monkeys. Animals (n=16/group, age 11–22 years) were treated immediately af...
