Objective: To evaluate musculoskeletal development using pQCT in children with coeliac disease (CD) on gluten free diet (GFD) compared with age and gender matched healthy controlsMethod: 38 children (18 males) with CD on GFD for a duration of 3.6 years (0.6, 12.5) underwent pQCT at 4%, 38 and 66% tibial sites. Bloods were collected in CD children only. Results reported as median (range).Result: Median TTG was 1.8 IU/l (0.1, 114) wi...

Introduction: Osteogenesis imperfecta is a rare disease leading to immobility by recurrent fractures, immobilization, short stature and muscular weakness. Beside drug treatment and surgical procedures physiotherapy is the most important treatment approaches to increase mobility. The objective of our analysis was to evaluate the effect of a new standardized 12 months physiotherapy concept including whole body vibration over 6 months on motor function and bone mineral density in...

Background: Treatment with multipotent mesenchymal stromal cells (MSC) has the potential to ameliorate mesodermal disorders.Objective: To treat severe osteogenesis imperfecta (OI) with fetal MSC.Methods: Ten years ago, we treated a fetus with OI type III (COL1A2: c.3008G>A, p.Gly1003Asp) in utero with fetal HLA-mismatched MSC. The procedure was uncomplicated. At the age of 4 months i.v. pamidronete treatment was starte...

Aim: Osteoporosis and resulting spontaneous fractures in young patients with neurological impairments living outside institutions have not received much attention. The aim of this study was to determine the degree of demineralization in children and teens with such disabilities living in South Lebanon, an under privileged region.Subjects and methods: We reviewed 40 patients attending outpatient clinics in a referral rehabilitation center in South Lebanon...

Background: Cannabinoid receptors are expressed in synovial joints but their role in joint disease is unknown. Here we examined the role of the type 2 cannabinoid receptor (CB2) in the pathogenesis of age-related osteoarthritis and osteoarthritis caused by destabilisation of the medial meniscus (DMM) in WT and CB2-deficient mice (Cnr2−/− mice).Methods: The severity of arthritis was graded histologically according to standard techni...

Abaloparatide (ABL) is a novel analog of hPTHrP (1–34) in clinical development for treatment of osteoporosis. This study evaluated the long-term effects of ABL on BMD and bone strength in aged osteopenic, ovariectomized (OVX) monkeys. Four groups of ≥9-year-old female cynomolgus monkeys underwent OVX and one group underwent Sham surgery. After a 9-month bone depletion period, increases in bone markers and decreases in BMD by DXA and pQCT were observed for OVX groups...

Fibroblast growth factor-23 (FGF23) is a bone derived phosphate-regulating hormone which is elevated in hypophosphataemic rickets. Recent findings demonstrate iron deficiency as a potential mediator of FGF23 expression and murine studies have shown in utero effects of maternal iron deficiency leading to increased FGF23 concentration and disordered bone development (Clinkenbeard. JBMR 2013). Children with rickets in rural Gambia, West Africa, have high prevalences of i...

Objectives: Fractures are common in older children. There are only few population-based studies on fractures in infants. Child abuse is a possible trauma mechanism, especially in younger children. New national guidelines for increasing awareness of child abuse and screening for suspected non-accidental traumas in Finland were given in 2003. Our goal was to establish fracture incidence and epidemiologic fracture patterns in children under the age of 1 year.<p class="abstext...

Objective: To evaluate safety and efficacy after 5 years of treatment with asfotase alfa in adolescents and adults with hypophosphatasia (HPP) in a Phase 2, open-label, randomized, dose-ranging study (NCT01163149).Methods: Treatment with subcutaneous asfotase alfa 0.3 or 0.5 mg/kg per d was compared with no treatment (control) for 6 months in patients aged 13–66 years. After 6 months, all patients (treatment and control groups) received active treat...
