Background: Congenital nephrogenic diabetes insipidus (arginine vasopressin resistance) is a rare inherited disorder characterized by insensitivity of the kidney to the antidiuretic effect of vasopressin. About 90% cases nephrogenic diabetes insipidus is an X-linked recessive disorder caused by variants in the AVP V2 receptor gene (AVPR2). In the remaining cases (10%) the disease is autosomal recessive or dominant and, for these patients, variants in ...

Background: 5-α-reductase type 2 enzyme catalyzes the conversion of testosterone into dihydrotestosterone, a potent androgen responsible for male sexual development during the fetal period. From 2017 to 2019, a homozygous hg38_chr2:31529414 C>T variant in SRD5A2 gene have been identified in 3 unrelated patients with DSD 46,XY of Buryat origin. The variant has been previously reported in one patient from China (Song et al, 2019) and l...

Aldosterone deficiency and resistance: The different faces of renal salt loss

Laurer Elisabeth , Tischlinger Katharina , Montero-Lopez Rodrigo , Blaschitz Alexandra , Wimleitner Marlene , Hoertenhuber Thomas , Hoegler Wolfgang

Introduction: Heritable conditions causing aldosterone deficiency (hypoaldosteronism) or target-organ resistance (pseudohypoaldosteronism, PHA) can lead to life-threatening salt-wasting crises in early life. Prompt evaluation and correct interpretation of aldosterone and renin are crucial to guide differential diagnosis and further testing. Here we report on the similarities and differences of two neonates presenting with salt-wasting: Patient (P1) due to PHA ...

Correlations between the degrees of obesity and dyslipidemia in a pediatric population from Romania

Amalia Ioana Arhire , Papuc Teodora , Miruna Sanziana Chiper , Chiriac Malina , Stoica Alexandra , Tambrea Elena

Keywords: pediatric obesity, metabolic syndrome, dyslipidemia, abdominal obesity, cardiovascular risk.Introduction: The prevalence of pediatric obesity is rising globally as well as in Romania and so are the complications of obesity. Dyslipidemia is one of the most frequent complications and is associated with cardiovascular risk even in children or teenagers. Evaluating the degree of obesity and the correlations between...

Mutations in MAGEL2 and L1CAM are Associated with Congenital Hypopituitarism and Arthrogryposis

Background: Congenital hypopituitarism (CH), involving deficiencies in one or more anterior pituitary hormones, is rarely observed in combination with severe joint contractures, termed arthrogryposis. Schaaf-Yang syndrome (SHFYNG), which has phenotypic overlap with Prader-Willi syndrome, may be associated with arthrogryposis. L1 syndrome, a group of X-linked disorders including hydrocephalus and spasticity of the lower limbs, may also present with generalized contractures in r...

Objective: To evaluate the impact of gestational age and birthweight on dehydroepiandrosterone and dehydroepiandrosterone-sulfate (DHEA and DHEA-S) in children born very preterm (VPT) appropriate for gestational age (GA) compared to children born at term (T).Methods: We recorded anthropometric parameters in 72 VPT (<32 GA) and 41 T (≥ 38 GA) aged 5.0–8.5 years. Birthweight standard deviation scores (BW-SDS) were calculated using INTERGROWT...

Background: The C3 epimer of 25-hydroxi-vitamin D3 (Epi25OHD3) is present in the pediatric and adult population and varies according to age. If it measurement is clinically relevant and should be considered to classify Vitamin D status is still unknown.Objective: To measure 25OHD3, 25-hydroxy-Vitamin D2 (25OHD2) and Epi25OHD3 and to compare them with PTH and calcemia.Method: Subjects: Children between 5 and 8 years of age born very...

Background: Very preterm neonates are at risk for metabolic syndrome later in life. Our objective was to compare anthropometric measures and insulin resistance variables between children who were born very preterm (VPT, <32 gestational weeks) and term (T, >37 gestational weeks), and adequate for gestational age (AGA).Methods: In this cross-sectional cohort study we recruited 113 children 5.0 to 8.5 years old from the preterm clinic of our institu...

Introduction: Higher evening cortisol level has been previously described in very preterm infants, possibly reflecting increased Hypothalamic-Pituitary-Adrenal Axis (HPA) tone or alterations in HPA regulation throughout the day. These relatively subtle differences in HPA axis function in preterm compared to full-term children may become meaningful in terms of metabolic risk later in life if sustained over time. Still, only a few studies have investigated wheth...
