Introduction: Generation of neutralizing antibodies (Nab) is a complication in enzyme replacement therapies and can lead to loss of treatment efficacy. Asfotase alfa (AA) was recently approved as the first replacement therapy in severe hypophosphatasia (congenital deficiency of alkaline phosphatase [TNSALP]). We report a case of neutralizing antibody mediated loss of efficacy of AA treatment in hypophosphatasia and the successful result of immune tolerance ind...

Background: Dietary carbohydrate restriction in the treatment of obese adolescents could cause a substantial shift in the substrates used as an energy source, inducing changes on body composition and metabolism, but experience in this age range is limited.Objective: We assessed the influence of 6 months of dietary carbohydrate restriction on body composition and lipid and carbohydrate metabolism in obese adolescents.Method: Thirty-...

Abstract: The SARS-CoV-2 virus uses ACE2 combined with the transmembrane-protease TMPRSS2 to enter and infect thyroid follicular cells. Studies have reported a higher incidence of hyperthyroidism cases during the COVID-19 pandemic compared to pre-pandemic periods. Studies have also been reported cases of thyroid dysfunction early after mass covid vaccinations. However, there are insufficient data to confirm these associations in children.<p class="abstext"...

Background: Children suffering from chronic liver disease (CLD) may develop rickets, impaired bone mineralization and are exposed to an increased risk of osteoporotic fractures. Bisphosphonate (BP) is used in children to increase the bone density and reduce the fracture incidence. Up to date, no study showing the effect of this treatment in children suffering from CLD has been reported.Objective and hypotheses: Evaluate the effect of BPs in children with...

Managing Graves' disease (GD) should be simple. Stop the immune system from targeting the TSH receptor and the disease is cured. Unfortunately this is not yet feasible in most young people and GD is not a trivial condition for those affected. There are significant advantages and disadvantages of all current treatments with no easy way forwards for many and the family's decisions will reflect their perceptions of medical, radiation and surgical risk. The fact that two o...

Introduction: Primary congenital hypothyroidism (PCH), defined as thyroid hormone deficiency, can be viewed as an anatomical, clinical, biochemical and radiological spectrum.Its etiology includes thyroid dysgenesis (85%) with defects in thyroid gland development and thyroid dyshormonogenesis (15%) with inborn error of thyroxine synthesis or release.There is growing evidence that precise characterization of ...

Introduction: Wilms tumor is the most frequent pediatric renal malignancy and its usual presentation is an abdominal mass or hematuria. Unusual presentations have also been reported, such as paraneoplastic syndromes (acquired von Willebrand disease, sudden death due to pulmonary embolism and Cushing syndrome). These conditions can precede, occur concomitantly or present in a later phase of tumor development. Precocious puberty, as paraneoplastic endocrine synd...

Background: Disorders/differences of sex development (DSD) differ from other rare conditions which are often accompanied by significant morbidity and mortality. With limited exceptions, DSD are not life-threatening and do not predict a given level of physical health or health-related quality of life across the lifespan. The birth of a child with DSD is anxiety-provoking. Stressors include weathering drawn-out diagnostic testing, difficulty absorbing complex medical information...
