Objectives: Vitamin D has an important effect on bone but there are no trials that directly address the boosting of serum levels of 25-hydroxyvitamin D (25OHD) in bone microarchitecture in Juvenile-onset Systemic Lupus patients (JoSLE). The aim of this study was to evaluate the effect of vitamin D supplementation on bone microarchitecture parameters using HR-pQCT in JoSLE patients.Methods: This study was a randomized double-blind placebo-controlled 24-we...

Although Vitamin D deficiency is the most common form of rickets worldwide, when there is a failure to respond to cholecalciferol, inborn errors of vitamin D metabolism should be considered. We describe two unrelated individuals who presented with early onset rickets characterised by reduced serum levels of 25(OH)D and 1,25(OH)2D, and a deficient response to Vitamin D2/D3 and calcitriol. Case 1: A Caucasian Australian girl with non-consanguineous parents ...

Epilepsy is a relatively common condition of childhood, with anti-epileptic drugs (AEDs) the mainstay of medical therapy. AED use in adults has been shown to be associated with impaired bone density and increased risk of bone fracture. Paediatric data are more limited particularly in relation to fracture risk and skeletal geometry.This study aimed to examine the within-pair differences in fracture prevalence and bone, muscle and balance parameters in sex...

Burosumab, a monoclonal antibody targeting fibroblast growth factor 23, is now available for clinical use in children with X-linked hypophosphatemia (XLH). We aimed to explore the effects of burosumab in children with XLH in a clinical setting, considering: a) Biochemistry b) Growth c) Lower limb deformity (LLD) d) Radiology e) Motor function<p class="abstext"...

Background: It is known that one of the features of rheumatoid arthritis (RA) is a generalized bone loss, therefore important tasks for the physician are timely evaluating of the risk of fractures and approving osteoporosis treatment in patients with RA.Objectives: Through the Programme of the Russian Association of Rheumatology for the diagnosis, prevention and treatment osteoporosis (OP) in patients with RA we evaluated the 10 year probability of major...

Aim: We present the case of a 36y female patient with multiple fragility fractures after the age of 21 and mutations in COL1A1, COL1A2 and GNAS genes.Material and methods: A 36y female patient with multiple fractures of the axial and appendicular skeleton was referred to us for consultation. The patient was born with hexadactyly of the left foot and had a history of mild thoracolumbar scoliosis (10°) and medium height (165 cm) with no other history ...

Osteoporosis pseudoglioma syndrome (OPPGS) is a rare autosomal recessive disorder characterised by congenital or juvenile-onset blindness, severe juvenile-onset osteoporosis, and skeletal fragility. OPPGS is caused by loss-of-function mutations in the LRP5 gene, a member of the LDL receptor family. It activates the canonical Wnt/β-catenin pathway, regulating osteoblastic bone formation. We investigated a 40-year-old Caucasian male presenting with congenital blind...
