Dual X-ray Absorptiometry in Children With Hypophosphatasia Treated with Asfotase Alfa: A Pooled Post Hoc Analysis

Simmons Jill H. , Rush Eric T. , Petryk Anna , Zhou Shanggen , Martos-Moreno Gabriel Á.

Hypophosphatasia (HPP) is a rare, inherited, systemic disease characterized by deficient tissue-nonspecific alkaline phosphatase activity. Common manifestations in children include impaired skeletal mineralization, short stature, and reduced physical function. Asfotase alfa is an enzyme replacement therapy approved for treatment of patients of any age with pediatric-onset HPP. The utility of dual X-ray absorptiometry (DXA) as a diagnostic tool or measure of treatment effective...

Tolerability and Feasibility of Whole Body Vibration and its Effects on Muscle Function and Bone Health in Patients with Dystrophinopathy

Petryk Anna , Polgreen Lynda , Marsh Jamie , Lowe Dawn , Hodges James , Karachunski Peter

Background: Dystrophinopathies, including Duchenne (DMD) and Becker (BMD) muscular dystrophy, are X-linked muscle wasting disorders caused by mutations in the dystrophin gene. Dystrophin deficiency compromises functional integrity of the muscle fibers leading to progressive weakness, accompanied by a gradual bone loss.Objective and hypotheses: This study’s goal was to evaluate the effect of whole body low magnitude vibration (WBLMV) on timed motor p...

Hypophosphatasia (HPP) is a rare, inherited, systemic disease caused by mutation(s) of the ALPL gene encoding tissue-nonspecific alkaline phosphatase (ALP), resulting in deficient ALP activity. Asfotase alfa is an enzyme replacement therapy approved for treatment of patients with pediatric-onset HPP. The global HPP Registry is an observational, prospective, multinational study (NCT02306720; EUPAS13514) established to collect real world clinical data from patients of a...

Hypophosphatasia (HPP) is a rare, inherited metabolic disease caused by deficient activity of tissue non-specific alkaline phosphatase (TNSALP). In children, HPP has a heterogeneous clinical presentation, frequently with nonspecific musculoskeletal and systemic manifestations, often leading to misdiagnoses and substantial delays in diagnosis. Data from 323 children with confirmed HPP diagnosis (aged <18 years, ALP activity below the reference range and/or ALPL mut...
