Hypoparathyroidism results in low bone turnover and increased bone mineral density (BMD). Replacing deficient PTH with rhPTH(1–84) has the potential to correct these skeletal abnormalities. To investigate the effect of rhPTH(1–84) on BMD and bone turnover markers (BTMs), data from two studies were assessed.REPLACE, a double-blind, multicenter, placebo-controlled study, randomized 134 patients with hypoparathyroidism to receive once-daily rhPTH(...

Abaloparatide (BA058) is a synthetic analog of PTHrP1–34 which greatly increases bone mass and bone strength with preservation of normal bone quality in animal models of osteoporosis. Daily s.c. abaloparatide (ABLSC) at doses of up to 80 μg daily in postmenopausal women with osteoporosis for up to 48 weeks were associated with increases in spine and femoral neck BMD of up to 12.9 and 4.1% respectively and good safety and tolerability. The increa...

Background: Peroxisomal Biogenesis Disorders (PBD) is a group of rare metabolic diseases in which peroxisomal function is disrupted. PBD encompasses Zellweger Syndrome Spectrum (ZSS) disorders, which range in severity from classical ZS with severe neurological impairment and markedly reduced life expectancy to Refsum Disease presenting later in childhood. Recent fragility fractures in our ZSS patients in very early childhood prompted case series review.P...

Objective: Bone and muscle deficits are observed in patients with Crohn’s disease (CD). High-impact exercise (HIE), such as jumping based exercise, can provide hypertrophic and osteogenic stimulus, however to date there have been no studies of HIE in CD. This study aimed to assess the acceptability and feasibility of participating in HIE in adolescents and adults with CD.Methods: Two anonymous questionnaires surveyed adolescents and adults, respecti...

Relatively little is known about immediate consequences of continuing vs interrupting long-term bisphosphonate treatment. This report describes changes in bone turnover and BMD in a 1-year, dose-finding trial of the calcium-sensing receptor antagonist MK-5442 in postmenopausal, BP-treated women, randomized to continued alendronate 70 mg weekly, switch to placebo, or switch to MK-5442. Recruited women (n=526) had taken alendronate for ≥12 months and an oral BP fo...

Objectives: Creation of reference curves for areal bone mineral density (aBMD) and bone mineral content (BMC) with consideration of relevant anthropometric variables.Methods: Analysis of the dual-energy X-ray absorptiometry (DXA) data collected as part of the Bone Mineral Density in Childhood Study1, including 2012 boys and girls, 5–22 years old, with a total of 10 525 visits, resulting in aBMD and BMC observations at the lumbar spine, hi...
