Background: The Dutch HYPOthalamic and PITuitary gene (HYPOPIT) study investigates the genetic and non-genetic causes of isolated growth hormone deficiency (IGHD) and combined pituitary hormone deficiency (CPHD). Former projects within the HYPOPIT study showed that only a small minority of the Dutch IGHD and CPHD cases could be explained by mutations in GH1, GHRHR, HMGA2 and CDK6 in IGHD patients and PROP1, HESX1, POU1F1, LHX3</...

Background: Standard assays for serum cortisol measurements determine total cortisol (TC) concentrations but not the unbound biologically active serum free cortisol (sFC). Measurement of TC would be greatly influenced by alteration in cortisol-binding globulin (CBG) concentrations. It is, therefore, important to determine sFC levels when CBG levels are either decreased or increased.Objective and hypotheses: To determine basal and glucagon-stimulated sFC ...

Background: Mixed gonadal dysgenesis (MGD) is the second most frequent cause of XY disorders of sex development (DSD). Genotype is either X/XY or XY, while the phenotype ranges from partial to complete gonadal dysgenesis, and from female to male external genitalia. Müllerian remnants are present in these patients because of insufficient or untimely foetal secretion of Müllerian inhibiting factor (MIF).Aim: To assess the therapeutic policy of ph...

Background: Prader–Willi syndrome (PWS) is characterized by a switch from failure to thrive to excessive weight gain and hyperphagia with impaired satiety in early childhood. An elevated, more unfavorable ratio between acylated:unacylated ghrelin (AG:UAG) may be involved in the underlying mechanisms of this switch.Objective and hypotheses: To assess the evolution of the appetite regulating hormones AG, UAG, and the AG:UAG ratio in infants with PWS a...

Background: Non-alcoholic fatty liver disease (NAFLD) is considered the hepatic manifestation of metabolic syndrome. Accelerated catch-up in weight during infancy in subjects born term has been associated with increased risk for NAFLD in adulthood, but this association has not been studied in subjects born preterm.Objective and hypotheses: To investigate the associations of birth weight, gain in weight for length and accelerated catch-up in weight in the...

Background: Ovarian reserve is defined as the functional potential of the ovary, which reflects the number and quality of the follicles left in the ovary at any given time. In literature there studies about the evaluation of ovarian reserve after ovariectomy for tumors and cysts, using serum markers, such as inhibin-B, and anti-Mullerian hormone (AMH), combined to ultrasonographic markers, in adult women but none in peri-pubertal girls.Case presentation:...

Context: Clinical findings characterizing PWS are muscular hypotonia, abnormal body composition, developmental delay, behavioral problems, hyperphagia with obesity when food intake is not restricted and short stature. Endocrine problems are described, like hypogonadism, hypothyroidism and adrenal insufficiency and growth hormone (GH) deficiency. Hypothalamic dysfunction may be responsible for many features of PWS. Randomized controlled studies showed that GH t...

Background: Short stature has been associated with a reduction in health-related quality of life (HRQoL) and more problem behavior in children and adults. In adolescents who were treated with growth hormone (GH) because of persistent short stature after being born SGA, an increase in HRQoL and decrease in behavioral problems was seen during or right after cessation of GH-treatment. However, long-term data, to analyze if these positive effects remain many years...

Childhood obesity has increased in epidemic proportions worldwide. Complications of obesity represent a growing proportion of childhood morbidity. Albuminuria resulting from endothelial damage was recognized as a complication of obesity, implying higher cardiovascular risk.Aim: to investigate the association of albuminuria in obese children with metabolic and inflammatory parameters.Materials and Methods:</...

Background: The French population of the SAGhE study showed an increased morbidity and mortality due to cerebrovascular disease in growth hormone (GH) treated subjects compared to the general population. Cerebrovascular health can be assessed using neuroimaging markers on MRI. One of the markers is white matter hyperintensity (WMH).Objective: To assess cerebrovascular health by scoring WMH on MRI in young adults born sma...
