Objective: Osteogenesis imperfecta is characterized by hereditary skeletal fragility. Bisphosphonates are the first line medical treatment in moderate and severe OI types III/IV. There is no consensus regarding treatment beginning and treatment regimen in the first years. Objective of the presented project was the evaluation of the therapeutic effect of 1 year of bisphosphonate treatment (BP; neridronate i.v. 2 mg/kg body weight every 3 months) on vertebral shape and mobility ...

Objectives: Haemophilia A (FVIII deficiency) is an X-linked disorder of haemostasis with bleeding tendency, mainly in joints and muscles. Recurrent haemarthroses, subsequent immobilization and avoidance of contact sports, may affect these patients’ skeletal health.Methods: Evaluation of bone health was performed in 51 children with Haemophilia A (severe: 41, all on prophylaxis treatment), mean age: 11.7±3.6 years. Dual-energy X-Ray absorptiomet...

Introduction: Mortality after hip fracture is increased. However, only a few studies have explored for predictors beyond gender and age. Thus our aim was to study risk factors associated with increased mortality in hip fracture patients.Methods: Hip fracture patients (>50 years) admitted to a county hospital in 2004–2005 were consecutively invited for assessment at the hospital osteoporosis centre. A broad spectre of data was collected. Standard...

Denosumab (DMAb) significantly improves bone strength at the hip, estimated by FEA from QCT scans, from baseline (B/L) and vs placebo (Pbo) (Keaveny ASBMR 2010). We determined the extent and distribution of mass and thickness changes at the proximal femur, a key skeletal site for fracture risk, using a novel cortical bone mapping technique on the same serial QCT scans. A FREEDOM substudy included 80 women who underwent hip QCT scanning at B/L and months 12, 24 and 36 during DM...

Background: Primary hyperparathyroidism (PHPT) has evolved into an asymptomatic disease in the west. In contrast classic symptoms of PHPT have been reported to be common in the East with as many as 80–100% of PHPT patients presenting with bone manifestations in India.Objective: To describe clinical and biochemical profile of patients diagnosed with PHPT between years 2009 and 2012.Methodology: This was a retrospective study co...

Objective: To evaluate bone and muscle mass in children with inflammatory bowel disease (IBD) following infliximab (IFX) therapy.Methods: Prospective longitudinal study of 19 children (12 males), 17 crohn’s disease (CD), 1 ulcerative colitis (UC), 1 IBD unclassified (IBDU) of bone evaluation commencing treatment with IFX. Bone and muscle parameters were measured by pQCT at the non-dominant distal radius at 4 and 66% at baseline and 6 months. pQCT pa...

Objectives: Asfotase alfa (AA), an enzyme replacement therapy, is the only approved medical treatment for pediatric-onset hypophosphatasia (HPP), which is caused by deficient tissue-nonspecific alkaline phosphatase activity. We detail the long-term efficacy of AA observed from the pediatric clinical trial program.Methods: Efficacy data collected to study completion were pooled from 3 open-label, multicenter investigations of children who manifested HPP s...

Participation in high impact sports during growth increases bone quality. Gymnasts have previously displayed increased bone mass and strength at both the upper and lower limbs compared with controls. However, it is not yet understood how bone microarchitecture is affected by gymnastics participation, and if this differs based on gymnastics discipline. Therefore, the objective of this study was to investigate the influence of gymnastics discipline on bone microarchitecture in a...

Introduction: Paget’s disease of bone (PDB) has an autosomal-dominant mode of inheritance in one-third of cases. The germinal SQSTM1/P392L mutation is the most frequent mutation, present in 40% of patients with a familial form of PDB, and 8% of unrelated patients. Fibrous dysplasia (FD) is a rare bone disorder, mono or polyostotic, caused by post-zygotic mutations in GNAS gene, for which a PCR-clamping method was developed to ease their detection and avo...

Objectives: To evaluate musculoskeletal development using pQCT and DXA in childhood onset inflammatory bowel disease (IBD).Methods: Prospective longitudinal study with 12 months follow-up in 43 children (23 males) with IBD: 30 crohn’s disease(CD), 13 ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU). pQCT at 4% and 66% radius, DXA for total body (TB), lumbar spine (LS) bone mineral content were assessed at baseline and 12 mo...
