GH treated children with IGF1 deficiency and excluded GH insensitivity despite normal GH secretion may attain similar final height as children with GH deficiency

Smyczynska Joanna , Lewinski Andrzej , Stawerska Renata , Hilczer Maciej

Introduction.: The diagnosis of GH deficiency (GHD) is based on decreased GH peak in stimulating tests (GHST). Recently, GHD has been re-defined as secondary IGF1 deficiency (IGFD). However, IGF1 may increase during GH therapy in the patients with normal GH peak in GHST, suggesting a diagnosis of non-primary IGFD (npIGFD).The aim of the study was to compare GH therapy effectiveness in children with GHD and with npIGFD (responding to GH administration des...

Reference curves for body fat (%) for Danish children evaluated by skinfolds and dual-energy X-ray absorptiometry

Wohlfahrt-Veje Christine , Tinggaard Jeanette , Mouritsen Annette , Hagen Casper , Grunnet Mikkel , Tefre de Renzy-Martin Katrine , Boas Malene , Holm Pedersen Jorgen , M Main Katharina

Background: Over the last 60 years body composition of young people have changed towards increased fatness. Whole body fat percentage (%BF) derived from dual energy X-ray absorptiometry (DXA) scans are (although often not available) widely recognized as a better measure of fatness than BMI.Objective: We aimed to provide reference materials for %BF of healthy Danish children evaluated by skinfold measurements and DXA and to compare sensitivity and specifi...

Unaltered sex steroid levels, but elevated serum IGF1 in healthy boys with pubertal gynaecomastia

Grunnet Mieritz Mikkel , Sorensen Kaspar , Aksglaede Lise , Mouritsen Annette , Hagen Casper P , Juul Anders

Introduction: The presence of glandular breast tissue in males around puberty, pubertal gynaecomastia, is a very common (40–60%) condition although the aetiology behind is poorly understood. It is generally accepted that pubertal gynaecomastia is caused by an excess of estrogens and/or a deficit of androgens. However, other hormones such as prolactin, GH and IGF1 may also affect ductal growth of the breast.Design: A cross-sectional study of 518 heal...

Subclinical hypothyroidism in obese children: the influence of L-thyroxin treatment on metabolic comorbidities and a success of dietary therapy

Matusik Pawel , Januszek-Trzciakowska Aleksandra , Malecka-Tendera Ewa

Introduction: Subclinical hypothyroidism (sHT) is defined as elevated level of TSH with normal levels of thyroid hormone. In obese children there is a high frequency of this disturbance. However, the influence of sHT on therapy success and an appearance of metabolic complications in childhood obesity is unclear. Furthermore, the supplementation L-thyroxin (L-T4) in this case seems to be very controversial.Aim: The...

Final height of a group of patients with congenital adrenal hyperplasia

Ferreira Marta , Santos Sonia , Pereira Ester , Vale Beatriz , Cardoso Rita , Dinis Isabel , Mirante Alice

Introduction: The final height of children with congenital adrenal hyperplasia (CAH) seems to be compromised. That can happen because of the disease itself or because an excessive dose of corticoids used during treatment. This work evaluates the final stature SDS of a group of patients with CAH and correlates it with 17-hydroxyprogesterone levels (17OHP) and corticoid dose at 10 years of age and at puberty onset.Methods: Selection of children with CAH di...

Sex steroid priming in differential diagnosis between idiopathic GH deficiency and constitutional delay of growth and puberty

Radin Raffaella , Moro Mirella , Scacchi Massimo , Cavagnini Francesco , Danesi Leila , Persani Luca

Priming with sex steroids prior to stimulation tests for the diagnosis of GH deficiency (GHD) in peripubertal years remains controversial, though some evidence suggests its utility in improving the specificity of GH testing for the distinction between idiopathic GHD (IGHD) and constitutional delay of growth and puberty (CDGP). However, few data are available on the final height (FH) of untreated CDGP patients. In order to better understand the usefulness of priming, we analyze...

Serum levels of 25(OH)-vitamin D and adipokine’s profile in obese children and adolescents

Caragheorgheopol Andra , Gherlan Iuliana , Vladoiu Suzana , Alexiu Florin , Padure Adriana , Schipor Sorina

Background: Low-serum concentrations of 25(OH)-vitamin D are associated with insulin resistance in adults. Recent in vitro studies have suggested that vitamin D may play a role in the regulation of adiponectin, leptin and resistin; since all these adipokines are related to insulin sensitivity modulation, they might represent a link between vitamin D status and insulin resistance.Aim: To identify possible correlations between 25(OH)-vitamin D ser...
