Objectives: Denosumab (Dmab) is a monoclonal antibody targeting RANKL administered by sub-cutaneous injection. Given its convenient mode of administration, our goal was to assess the safety and efficacy of Dmab compared to intravenous zoledronic acid (ZA) in pediatric osteoporosis.Methods: In this one-year pilot study (NCT02632916), children 4–16 years with low-trauma fractures due to osteoporosis were randomized 1:1 to receive ZA 0.025 mg/kg or Dma...

Objectives: Denosumab (Dmab) is a monoclonal antibody targeting RANKL administered by sub-cutaneous injection. Recent reports have raised concern about the ‘rebound phenomenon’ (hypercalcemia and increases in bone turnover markers, BTM) following Dmab in adults, and during treatment in children with osteogenesis imperfecta. The purpose of this report was to explore this phenomenon in children with osteoporosis associated with lower bone turnover.<p class="abstext...

Objectives: To evaluate musculoskeletal trajectories in children with newly diagnosed Crohn’s disease (CD), and to determine whether children treated with anti-tumour necrosis factor-alpha antibody (anti-TNF, TREATED vs NAÏVE) had persistent deficits at two years.Methods: This was a single-centre prospective, observational inception cohort study. Children with CD underwent assessments within 6.5±9.5 days from diagnosis and annually for two...

Objectives: Osteoporosis is a frequent cause of morbidity in boys with glucocorticoid (GC)-treated Duchenne Muscular Dystrophy (DMD). We sought to determine the frequency and characteristics of the two most debilitating types of fractures, vertebral and long bone (VF and LBF), in pediatric DMD.Methods: This was a prospective, bi-centre, single-visit observational study in boys 4 to 17 years of age with genetically-confirmed DMD. The bone health assessmen...
