Background: Mutations in the nicotinamide nucleotide transhydrogenase (NNT) gene are a rare cause of primary adrenal insufficiency (PAI), as well as cardiomyopathies and functional impairment of the gonads.Objective: Despite the description of different NNT mutations in homozygosis and compound heterozygosis in PAI patients, it remains to be clarified to which extent the function and expression of the m...

Background and hypothesis: Mitochondrial disorders are multisystemic conditions associated with sensorineural hearing loss, encephalomyopathy, lactic acidosis, and non-autoimmune diabetes. The majority of molecular etiologies involve mutations in the genes encoding the oxidative phosphorylation system's components. Superoxide generation is significantly increased and causes oxidative damage in the affected tissues in these disorders. The establishment of ...

Introduction: XLH is caused by mutations in PHEX leading to increased FGF23 levels, phosphate wasting, and impaired endogenous calcitriol synthesis. Affected patients present with rickets and diminished growth velocity during childhood, and osteomalacia and short stature in adulthood. Adult height is linked with health within and across generations suggesting that adult height may be a potential tool for monitoring health conditions, e.g., XLH.<p ...

Changes in Waist-to-Height Ratio during Preschool Years Differ between Children being Obese or Overweight at Five Years of Age Compared with not Overweight Children

Background: Growth patterns in early childhood are important for predicting adult overweight or obesity. BMI is the most widely used measure. However BMI does not reveal much regarding the distribution of fat, for example the visceral fat that in adults is highly correlated with metabolic risk. Waist-to-Height Ratio (WtHR) is in adults a better measure for visceral fat and studies indicate that the same applies to children.Objective and hypotheses: To st...

Background: Screening for autoimmune thyroid disease in children and adolescents with type 1 diabetes lacks consensus. Optimal screening methods should benefit the patients and reduce costs to healthcare.Objective and hypotheses: To, at diagnosis of type 1 diabetes, determine the predictive value of thyroid autoantibodies, thyroid function, islet autoantibodies, and HLA-DQ for autoimmune thyroid disease.Method: At diagnosis of type...
