A randomised double-blind placebo-controlled trial of vitamin D supplementation in juvenile-onset systemic lupus erythematosus: positive effect on trabecular microarchitecture using high resolution peripheral quantitative computed tomography

Paupitz Juliane , Lima Glauce , Aikawa Nadia , Alvarenga Jackeline , Pereira Rosa

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...

A novel form of congenital rickets due to a recurrent gain of function mutation in CYP3A4

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 ...

Patients treated with anti-epileptic drugs have a higher rate of fracture and impaired bone and muscle development compared with controls: results from a pilot study

Simm Peter J , Seah Sebastian , Mackay Mark , Freeman Jeremy , Petty Sandra J , Wark John D

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...

Nine-month follow-up data on biochemical, clinical, radiological and functional parameters in a clinical cohort of children at Evelina London Children's Hospital with X-linked hypophosphataemia treated with Burosumab

Sandy Jessica L , Gilbey-Cross Robyn , Santos Rui , Sakka Sophia D , Cocca Alessandra , Morris Mavali , Cheung Moira S

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...

Skeletal effects of the gastrin receptor antagonist netazepide in H+/K+ATPase beta-subunit deficient mice

Epidemiological studies suggest that patients using proton pump inhibitors (PPIs) have increased fracture risk. We have previously shown that H+/K+ATPase beta-subunit knockout (KO) mice have reduced BMD, BMC and mechanical bone strength compared to WT. Like users of PPIs, these mice have elevated serum gastrin levels due to high gastric pH. We wanted to study whether elevated gastrin influences bone quality in these mice.Female KO and WT mice aged 6 week...

A clinical study to examine thresholds of joint space width and joint space area for identification of knee osteoarthritis

Objective: Osteoarthritis (OA) is a degenerative, slowly developing joint disease. Although clinical indications of OA can vary among different definitions there is a general agreement that the disease is associated with cartilage narrowing. However, there is no general consensus about the threshold below which the joint space width (JSW)/joint space area (JSA) can be certain indicators for the state of OA. Therefore this study evaluates these limits to reveal quantitative inf...

A novel feature selection algorithm based on bone micro architecture analysis to identify osteoarthritis

Ljuhar Richard , Norman Benjamin , Ljuhar Davul , Haftner Tobias , Hladuvka Jiri , Bui Thi Mai Mary , Canhao Helena , MariaRodrigues Ana , Gouveia Nelia , Branco Jaime , Nehrer Stefan , Fahrleitner-Pammer Astrid , Dimai Hans-Peter

Objective: Texture information of the subchondral bone area (SBA) of 2D radiographs represents a promising possibility for evaluating the state of osteoarthritis (OA). However such features are likely to vary within the SBA and therefore the selection of the region of interest (ROI) plays a crucial role. Thus, a feature selection algorithm (FSA) is being applied in order to determine ROIs that enable an optimum discrimination between patients with and without OA.<p class="...
