: This study analyses the long-term effect of rhGH on final height (FH) and bone health in renal transplanted patients.Twenty-one young adult patients, aged 17–26 years, were studied. Group A consisted of 15 patients (12 boys) who received rhGH during 3.0 years before transplantation. After transplantation three boys needed rhGH again for 3.5 years. In group B six patients (three boys) didn’t need rhGH before transplantation, three girls receiv...

Patients with osteoporosis require treatment with therapies that reduce the risk of fracture which at the spine is significantly influenced by bone microarchitecture. Quantitative computed tomography (QCT) and dual X-ray absorptiometry (DXA) allow measurement of bone mineral density (BMD), a known indicator of fracture risk. Trabecular bone score (TBS) is a novel gray-level measurement derived from spine DXA image texture that is related to microarchitecture and associates wit...

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 ...

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...

Tumour necrosis factor receptor-associated factor 6 (TRAF6) plays a key role in osteoclastogenesis through the regulation of RANK/CD40 TRAF6-mediated signaling. Mice deficient in TRAF6 exhibit high bone mass and were protected against inflammation-induced bone loss. Here we describe the effects of a small-molecule 6877002 that has been shown to prevent the binding of TRAF6 to its domain on RANK/CD40 receptor on osteoclast formation in vitro and in vivo and on...

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 ...

Objective: The study evaluated the efficacy of the therapeutic compliance in brittle bone disease applied to frail elderly people affected by osteoporosis and in treatment with Denosumab.Methods: We studied people ≥75; 43 women (mean age 83±3) and 14 men (mean age 85±3), all suffering from femoral osteoporosis T-score <−4. In 34 women and 6 men, we discovered 1–2 vertebral fractures. They have been treated with Den...

Objective: The BoneXpert method for automated bone age determination from hand X-rays also determines the cortical thickness T and the bone width W in the three middle metacarpals. From these, the method derives the cortical area A=π W T (1 – T/W), the metacarpal index MCI =A/(WW) and the Bone Health Index. Recently, the method has been extended down to new-borns, and the aim of this study is to report reference curves for these bone measures.M...

Ankylosing spondylitis is a chronic inflammatory rheumatic disease, characterized by axial pain and osteoproliferation, leading to painful rigidity of the spine and disability. In contrast with this bone formation, bone loss is an early event in this disease, and an increased vertebral fracture risk (but not non-vertebral fracture risk) has been reported in these patients.Prospective studies have shown that potent anti-inflammatory drugs, such as anti-TN...

The aim of this study was to evaluate the trabecular bone score (TBS), bone mineral density (BMD) and body composition in women of various ages.Materials and methods: 494 women aged 41–89 years (mean age, 63.6±0.4 years; mean height, 1.61±0.003 m; and mean weight, 74.0±0.6 kg) were examined. The patients were divided into the following age-dependent groups: 40–49 years (n=35), 50–59 years (n=130), 60–6...
