Determinants of the Peak GH Response of the Glucagon Stimulation Test in Slowly Growing Children

De Schepper Jean , Dewulf Charline , Craen Marghareta , Cools Martine , Gies Inge

Background/Aim: Currently, the minimum of the GH peak (pGH) to GH provocative stimuli, including the glucagon stimulation test (GST), has been arbitrary set in children at 7 µg/L, irrespective of gender and age. Several doses (fixed or per bodyweight) and ways of administration (IM or SC) of glucagon are being used in daily practice. This retrospective study explores the influence of gender, age, and adiposity on the pGH after a maximally effective glucag...

Consecutive Lynestrenol and Cross-Sex Hormone Treatment in Biological Female Adolescents with Gender Dysphoria: A Retrospective Analysis

Tack Lloyd , Craen Margarita , Dhondt Karlien , Vanden Bossche Heidi , Laridaen Jolien , Cools Martine

Background: Progestins such as lynestrenol (L) can be used in female to male (FtM) adolescents with gender dysphoria (GD) who have advanced pubertal development to reduce the psychological burden of menstruation. L can later be combined with cross-sex hormones (testosterone esters) (L+T). L is much cheaper and easier to administer than GnRHa. To date, few data exist on the (side) effects of progestins for this indication.Objective and hypotheses: To repo...

Effects and Side Effects of Cyproterone Acetate Alone and in Combination with Estrogens in Natal Male Adolescents with Gender Dysphoria

Tack Lloyd , Craen Margarita , Dhondt Karlien , Bossche Heidi Vanden , Laridaen Jolien , Cools Martine

Background: Male to female (MtF) gender dysphoric adolescents with advanced pubertal development can be treated with antiandrogenic progestins such as cyproterone acetate (CA). CA is much cheaper and easier to administer than GnRHa and can later be combined with cross-sex hormones (17β-estradiol) (CA+E). To date, few data exist on the (side) effects of progestins for this indication.Objective and hypotheses: To report the effects of consecutive CA a...

Early Medical Treatment of Children with Gender Dysphoria: an Empirical Ethical Study on Arguments of Proponents and Opponents Concerning Early Interventions

de Vries Martine , Vrouenraets Lieke , Wichmann Anne , Schermer Maartje , Fredriks Miranda , Delemarre-van de Waal Henriette

Background: Both The Endocrine Society and the World Professional Association for Transgender Health (WPATH) published guidelines for the treatment of children and adolescents with gender dysphoria (GD). The guidelines recommend the use of GnRH agonists in adolescence to suppress puberty, and the use of cross-sex hormones starting around age 16 for eligible patients. In actual practice, there is no consensus whether to use these early medical interventions. The aim of our stud...

Making Adult Height Prediction Complete: Forecasting the Age of the Growth Spurt and the Height and Velocity Trajectories Until Adulthood

Martin David , Mortensen Sofus , Jenni Oscar , Thodberg Hans Henrik

Background: Adult height prediction (AHP) based on bone age appears as an incomplete procedure – it does not reveal the path from the present to the end-point. Growth charts offer little help in this respect because they average over children with different age of growth spurt (AGS).Objective and hypotheses: To extend AHP by also forecasting AGS and the entire height and velocity trajectories until adulthood and displaying this in a growth chart mad...

Obstructive sleep apnea (OSA) is associated with the impairment of beta-cell response to glucose in children and adolescents with obesity

Rosaria Umano Giuseppina , Galderisi Alfonso , Aiello Francesca , Martino Mariangela , Di Sessa Anna , Marzuillo Pierluigi , Miraglia del Giudice Emanuele

Purpose: The main purpose of the study is to assess the association between obstructive sleep apnea (OSA) and insulin secretion in children with obesity.Objectives: To achieve our aim we have assessed OSA and measured insulin secretion by the using the oral minimal model (OMM) in a cohort of 77 obese children and adolescents.Methods: We retrospectively enrolled children and adolesc...

Suboptimal adherence to statin therapy in children and adolescents with HeFH despite a high therapeutic efficacy: is the cardiovascular risk underestimated?

Bruzzi Patrizia , Di Martino Marianna , Di Caprio Antonella , Filomena Madeo Simona , Lucaccioni Laura , Predieri Barbara , Iughetti Lorenzo

Background: Heterozygous familial hypercholesterolemia (HeFH) is characterized by severely elevated low-density lipoprotein cholesterol (LDL-C) levels and premature cardiovascular disease. European guidelines currently support the initiation of statin therapy by age 8-10 years in patients with HeFH to slow the progression of endothelial disfunction and to reduce the risk of cardiovascular disease in adulthood. However, to date, there is lack of data on adheren...

Background: Vernal keratoconjunctivitis (VKC) patients have an elevated incidence of growth hormone deficiency and thyroid diseases. Nevertheless, no auxological data are available in these subjects.Objective and hypotheses: The purpose of this study was to evaluate the auxological features in a cohort of patients with VKC.Method: This study included 179 Caucasian VKC patients (119 males, 60 females; mean age 9.63±2.98 years) ...
