Vertebral fractures (VF) defined by morphometric analysis of spine radiographs are the most common complication of osteoporosis. Those that come to medical attention, with symptoms such as back pain and kyphosis are termed clinical vertebral fractures (CVF) and account for significant morbidity and mortality. Although much progress was made in identifying loci for bone mineral density, the genetic determinants of CVF remain unclear. Here we present the initial results from a g...

Correlation of bioelectrical impendance analysis and dual energy X-ray absorptiometry for bone mineral content and bone mineral density in young healthy humans

Cvetko Erna Davidovic , Nesic Nebojsa , Milas-Ahic Jasminka , Drenjancevic Ines

Introduction: Bioelectrical impendance analysis (BIA) and dual enargy X-ray absorptiometry (DXA) are two most common methods used for body composition analysis. The aim of this study was to investigate: i) if there is a correlation between body mineral content (BMC) determined by BIA and by DXA for bone mineral content (BMC) and ii) correlation of BMC (BIA) vs bone mineral density (BMD) of L1–L4 spine, dual femur total mean and neck mean.Methods: Tw...

Tumor necrosis factor superfamily members in bone loss in men with end-stage chronic obstructive lung disease

Kochetkova Evgenia , Ugay Ludmila , Maistrovskaia Yuliya

Aim: To assess the relationships of serum osteoprotegerin (OPG), receptor-activator of nuclear factor-κB ligand (RANKL) and tumor necrosis factor-alpha (TNF-α) superfamily with bone composition in end-stage COPD.Methods: Body and bone composition, serum OPG, RANKL, TNF-α and its receptors (sTNFR I, sTNFR II), TNF-related apoptosis-inducing ligand (sTRAIL) levels were measured in 48 men end-stage COPD accepted for lung transplantation, and ...

Bone histology and histomorphometry: effects of 5 years of denosumab in the FREEDOM Extension

DMAb increases BMD and reduces bone resorption and risk of vertebral, nonvertebral and hip fractures in women with PMO. Transiliac crest bone biopsies in 47 subjects treated with DMAb for 1–3 years showed reduced bone turnover vs 45 Pbo-treated subjects, which reversed on treatment cessation. Since bone turnover reduction is sustained and fracture incidence low over 6 years’ DMAb treatment, we evaluated DMAb’s effects on tissue-level remodelling in the FREEDOM E...

Determinants of bone mineral density in long-term adult survivors of childhood cancer

Klap B C , te Winkel M L , den Hoed M , van Waas M , Neggers S J C M M , Boot A M , Pieters R , Pluijm S M F , van den Heuvel-Eibrink M M

Objectives: Osteopenia is a complication of childhood cancer treatment but it is unknown to which extend this occurs in adult survivors, and which subgroups are at risk. We examined bone mineral density (BMD) and assed the relative importance of potential determinants of low BMD in very long-term adult survivors of childhood cancer.Methods: The single-center cohort study included 410 adult CCSs (median age at diagnosis: 6.6 years (range: 0–17 years)...

Enhancement of fracture repair by upregulation of the innate immune response

Osteoporotic fractures are very common and represent an enormous unmet medical need. Our group has previously reported that addition of rTNF to the fracture site promotes fracture healing in C57/BL6 mice (Glass et al. PNAS 2011). Using a murine fracture model of endochondral healing, we observed that local addition of rTNF only accelerates fracture repair if administered within the first 24 h following injury. The optimal therapeutic dose is 1 ng. TNF is firs...

Aggravated bone density decline following symptomatic osteonecrosis in children with acute lymphoblastic leukemia

Objectives: Osteonecrosis (ON) and decline of bone mineral density (BMD) are serious side effects during and after treatment of childhood acute lymphoblastic leukemia (ALL). It is unknown whether ON and low BMD co-occur in the same patients, and whether these two osteogenic side-effects can mutually influence each other’s development.Methods: BMD and the incidence of symptomatic ON were prospectively assessed in a national cohort of 466 patients wit...

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...
