Reference values of cortical thickness, bone width, and Bone Health Index in metacarpals of children from age 0 y, as determined with an extension of the fully automated BoneXpert bone age method

Thodberg Hans Henrik , Thrane Peter , Martin David D.

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...

Effect of a mixture of calcium, vitamin D, inulin and soy isoflavones on bone metabolism in post-menopausal women: a retrospective analysis

Bevilacqua Maurizio , Righini Vellela , Certan Diana , Alemanni Matteo , Gandolini Giorgio

Introduction: A retrospective analysis we previously performed on post-menopausal women showed that the addition of inulin (3 g) and soy isoflavones (40 mg) to daily calcium (500 mg) and vitamin D3 (300 UI) supplementation was able to increase calcium absorption by 60%, while reducing circulating parathormone and leaving vitamin D3 levels unchanged. Therefore, we tested whether such a mixture could affect also bone metabolism.Method...

KRN23 effects on phosphate and vitamin D dysregulation in children <5 years old with X-Linked Hypophosphatemia (XLH)

Imel Erik , Carpenter Thomas , Gottesman Gary S , Martin Javier San , Mao Meng , Skrinar Alison , Whyte Michael P

Objectives: XLH features renal phosphate (Pi) wasting, hypophosphatemia, rickets, and skeletal deformities from elevated circulating levels of fibroblast growth factor 23 (FGF23). KRN23, an investigational fully human monoclonal antibody, binds FGF23 and inhibits its action. Our Phase 2 study of KRN23 in XLH children (ages 5–12 years) is demonstrating improvements in serum Pi and rickets. Here we present our Phase 2 trial evaluating the efficacy and safety of KRN23 in you...

Mass spectrometric immunoassay for intact parathyroid hormone: correlation with immunoassay and application to clinical samples

Couchman L , Taylor D , Krystans B , Lopez M , Prakash A , Sarracino D , Garces A , Vogelsang M , Peterman S , Vadali G , Robinson S , Moniz C

Introduction: Parathyroid hormone (PTH) measurement is of use in i) differential diagnosis of hypercalcaemia and ii) patients with renal impairment at risk of bone disease. PTH immunoassays are complicated by cross-reactivity with truncated (inactive) variant forms, which accumulate in patients with renal impairment. PTH assay variability is a critical governance issue in renal medicine, suggesting an MS-based reference method is required.Aim: To develop...
