Background: Chronic recurrent multifocal osteomyelitis (CRMO) is a rare inflammatory bone disease characterized by chronic non-infectious osteomyelitis. Spinal involvement has been reported in up to 26% of patients (1). Three studies evaluated the effect of Pamidronate (PAM) on spinal lesions in pediatric patients with CRMO (1, 2, 3) and showed partial or complete resolution of vertebral hyperintensities on MRI (1). However, the effect of Zoledronic acid (ZOL) in pediatric pat...

Although X-linked hypophosphatemic rickets (XLH) is characterized by hypophosphatemia leading to a generalized mineralization defect with rickets (and/or osteomalacia), densitometric studies point towards a tendency towards an elevated bone mineral density (BMD). The aim of this cross-sectional in vivo study was to assess bone geometry, volumetric BMD (vBMD), microarchitecture and estimated bone strength using high-resolution peripheral quantitative computed tomograph...

Objective: To assess the effect of mechanical loading in anorexia nervosa (AN) in vivo, by comparing bone geometry and microarchitecture in weight bearing versus non-weight bearing bone.Subjects and methods: A total of 26 female patients with AN, and 26 female controls matched on age and height were included. Bone geometry, volumetric bone mineral density (vBMD) and microarchitecture were assessed using HR-pQCT (Scanco Medical, Brütisellen,...

Objective: Hyperthyroidism leads to reduced mineral bone density and is associated with increased risk of fracture. Whether the effect of increased bone turnover is identical in cortical and trabecular bone in unknown. Using a cross sectional design we aimed to investigate which bone compartment is affected.Methods: Nineteen newly diagnosed patients with Graves’ disease (GD) and nineteen euthyroid controls matched on age, gender and menopausal statu...

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...

Objectives: Duchenne muscular dystrophy (DMD) is a rare hereditary X-linked muscular dystrophy affecting approximately 1:5.000 live borne males. The mobility and respiratory complications have been improved by implementing the glucocorticoid treatment in DMD, however, secondary osteoporosis, short stature and delayed puberty emerged as unwanted side-effects of the treatment. We aimed to evaluate the endocrinological complications in boys with DMD followed at our neuromuscular ...

BA058 is being developed as an anabolic therapy for the treatment of osteoporosis. Daily BA058 SC injection has produced promising safety and efficacy results in early clinical studies, and is currently enrolling in a Phase 3 fracture prevention study. There is, however, a significant need for an alternative to injection that improves patient convenience and compliance. We have investigated the use of a solid Microstructured Transdermal System (3M) for transdermal (TD) deliver...

Introduction: Mitochondrial dysfunction is associated with several clinical outcomes including diabetes and myopathy and is implicated in the human aging process. We previously showed that the mitochondrial DNA point mutation mtDNA3243A>G is associated with lower BMD and altered bone structure. The aim of this study was to assess bone turnover markers in individuals with the mutation and controls.Methods: We recruited 45 patients (29 female, 16 male)...
