Effect of odanacatib on bone density and estimated bone strength in postmenopausal women: a CT-based sub-study of the phase 3 long-term odanacatib fracture trial (LOFT)

Odanacatib (ODN), a selective oral inhibitor of cathepsin K, is in development for the treatment of osteoporosis. In the Phase 3, Long-Term ODN Fracture Trial (LOFT; NCT00529373), ODN significantly reduced fracture risk. This imaging sub-study primarily investigated the effect of ODN on volumetric BMD (vBMD) of the lumbar spine (LS) and total hip (TH) using quantitative computed tomography (QCT).Women aged ≥65 without baseline radiographic vertebra...

Sex hormone-binding globulin is associated with markers of vertebral fracture and vertebral fracture risk

Koromani Fjorda , Muka Taulant , Oei Ling , Zillikens Carola , Hofman Albert , Uitterlinden Andre G , Oei Edwin , Hans Didier , Franco Oscar H , Rivadeneira Fernando

Background: The relation between sex hormone-binding globulin (SHBG) and vertebral fracture (VFx) is unclear.Aim: To examine whether SHBG is associated with bone mineral density at lumbar spine (LS-BMD), trabecular bone score (TBS) and prevalent VFx.Methods: Data of 6224 men and women participants in the third visit of the first cohort (I-3) and the first visit of the second cohort (II-1) of a prospective population based cohort, w...

The association between diabetes, trabecular bone score, bone mineral density and vertebral fractures

Koromani Fjorda , Muka Taulant , Oei Ling , Zillikens Carola , Hofman Albert , Franco Oscar H , Uitterlinden Andre G , Oei Edwin , Hans Didier , Rivadeneira Fernando

Background: Fracture risk is increased in Type 2 diabetes (T2D) individuals. Bone mineral density (BMD) is inversely associated with fracture risk but paradoxically high in T2D individuals. Trabecular bone score (TBS) reflects bone microarchitecture and predicts fracture risk.Objective: We aimed to compare mean lumbar spine TBS (LS-TBS) and lumbar spine BMD (LS-BMD) values, across individuals with and without i) vertebral fracture (VFx), ii) T2D; and iii...

Phenotypic dissection of bone mineral density facilitates the identification of skeletal site specificity on the genetic regulation of bone

Kemp John P , Medina-Gomez Carolina , Estrada Karol , Heppe Denise , Zillikens Carola , Timpson Nicholas , Pourcain Beate , Ring Susan , Hofman Albert , Jaddoe Vincent V W , Smith George Davey , Uitterlinden Andre G , Tobias Jonathan H , Rivadeneira Fernando , Evans David M

Heritability of bone mineral density (BMD) varies at skeletal sites, possibly reflecting different relative contributions of environmental and genetic influences. To quantify shared genetic influences across different sites, we estimated the genetic correlation of BMD at the upper limb (UL), lower limb (LL), and skull (S) obtained from whole body DXA scans, using bivariate genome-wide complex trait analysis (GCTA). The study (n=9395) combined data from the Avon Longit...

Bivariate analyses of BMD and lean mass in children identifies variants with novel pleiotropic effects across six BMD loci and in the TOM1L2 locus

Medina-Gomez Carolina , Kemp John P , Heppe Denise H M , Tobias Jon H , Hofman Albert , Carola Zillikens M , Uitterlinden Andre G , Jaddoe Vincent W V , Evans David M , Rivadeneira Fernando

Background: Lean and bone mass are heritable traits with high phenotypic correlation (rho=0.44), likely reflecting the underlying mechanical and biochemical interactions between tissues.Aim: Estimate the shared heritability (genetic correlation) of both traits in children and identify genetic determinants displaying pleiotropic effects on lean mass and bone mass accrual.Methods: Participants make part of two prospective po...

Activated protein C increases osteoblast proliferation and BMP2 induced bone formation

Shen Kaitlin , Schindeler Aaron J , Cheng Tegan L , Xue Meilang , Little David G , Jackson Chris J

Introduction: Activated protein C (APC) plays an important role in the cutaneous healing of chronic wounds arising from orthopaedic surgery and has cytoprotective and anti-inflammatory properties which may also assist bone repair. The aim of this study was to examine whether APC could directly influence osteoblasts and increase bone formation in a rodent model.Methods: Proliferation of MG-63 osteoblast-like cells was quantified by MTT assay and direct co...

Introduction: The creatine kinase (CK) is a dimeric enzyme, involved in energetical metabolism. It is present in many tissues, but higher concentration in skeletal and cardiac muscle.Therefore, conditions that involve muscle tissue may increase this serum enzyme. Such enzyme elevation is usually observed in inflammatory myopathies and others autoimmune diseases.Sometimes some elevation in CK is not fully understood out off these co...
