The Growzen™ buddy smartphone application shows positive findings on adherence in Argentinian patients receiving growth hormone therapy for growth disorders

van Dommelen Paula , Arnaud Lilian , Assefi Aria , Lourdes Crespo Maria , Koledova Ekaterina

Background: Digital health solutions, such as the Growzen™ buddy smartphone application (app), can facilitate adherence to recombinant human growth hormone (r-hGH) treatment for patients with growth disorders. The app alerts patients when it’s time for an injection and allows patients and their caregivers to self-monitor growth, to build a routine and improve adherence. The app also contains educational resources to empower patients to be active in...

Acromegaly in a 14-year-old girl with pituitary adenoma

Fingerhut Karin , Krebs Andreas , Otfried Schwab Karl , Spiekerkötter Ute , van der Werf Natascha

Introduction: Acromegaly is a rare disorder, developed by overproduction of growth hormone (GH) and insulin-growth factor 1 (IGF-1), in most cases based on a pituitary adenoma. The increased IGF-1 and GH levels lead to the growth of acres and organs as well as metabolic changes. When manifesting before epiphyseal closure, a giant growth develops.Case Report: A Ukrainian girl presented at the age of 14 years with enlargem...

At present no European recommendations for the management of pediatric thyroid nodules and differentiated thyroid carcinoma (DTC) exist. Differences in clinical, molecular, and pathological characteristics between pediatric and adult DTC emphasize the need for specific recommendations for the pediatric population. An expert panel was instituted by the executive committee of the European Thyroid Association (ETA) including an international community of experts from a variety of...

Urinary steroid metabolite ratios: sex- and age-dependent changes and use for the differential diagnosis of inborn steroidogenesis disorders

S. Baranowski Elizabeth , Guran Tulay , C. Gilligan Lorna , Shaheen Fozia , Utari Agustini , M.H. Faradz Sultana , E. Van Herwaarden Antonius , L. Claahsen - van der Grinten Hedi , E. Taylor Angela , H.L. Shackleton Cedric , Arlt Wiebke

Background: Biochemical ratios of precursor-to-product urinary steroid metabolites have been proposed as surrogate markers of steroidogenic enzyme activity to aid the differential diagnosis of inborn disorders of steroidogenesis. Using ratios rather than total amounts facilitates analysis of single spot urine samples, more convenient than 24-h urine collections for young children. Previous studies examining the utility of these biochemical ratios have been lim...

Identification of a novel CYP11B2 variant in a family with varying degrees of aldosterone synthase deficiency

Background: Isolated aldosterone synthase deficiency is a rare autosomal recessive disorder caused by pathogenic variants in CYP11B2. To date, more than forty different pathogenic variants in the CYP11B2 gene causing isolated aldosterone synthase deficiency have been identified. We report on a novel pathogenic CYP11B2 variant.Case report: The second child (male) of consanguineous, healthy parents, presented shortly after...

Introduction: Childhood obesity is associated with alterations in hypothalamus-pituitary-adrenal axis activity. We tested the hypothesis that multiple alterations in the metabolism of glucocorticoids are required for the development of hypertension in children who become overweight.Methods: Timed spot urine for targeted gas chromatography-mass spectrometry steroid metabolome analysis was collected from (1) overweight/hyp...

A Structured Education Program on Hormonal Control and Quality of Life in Congenital Adrenal Hyperplasia: a study in Indonesia

Background: Classic Congenital Adrenal Hyperplasia (CAH) needs life-long treatment of glucocorticoids. Compliance with long-term medication is still challenging, particularly in developing countries. However, there has been no prospective study about the strategy to improve compliance in CAH and its relationship with hormonal control and quality of life (QoL) in CAH, especially in underprivileged countries such as Indonesia. This study aimed to determine the r...

11-oxygenated androgens as biomarkers in congenital adrenal hyperplasia: reference intervals for children

P.H. Adriaansen Bas , oude-Alink Sandra , W. Swinkels Dorine , A.M. Schröder Mariska , N. Span Paul , C.G.J. Sweep Fred , L. Claahsen - van der Grinten Hedi , E. van Herwaarden Antonius

Background: Patients with congenital adrenal hyperplasia (CAH) might suffer from hyperandrogenism. For diagnosing and treatment monitoring, usually levels of androstenedione (A4) and testosterone (T) are measured in blood. More recently, adrenal-specific 11-oxygenated androgens such as 11- hydroxyandrostenedione (11OHA4), 11-ketoandrostenedione (11KA4), 11-hydroxytestosterone (11OHT), and 11-ketotestosterone (11KT) were introduced as promising biomarkers, but ...

Validation of referral criteria for growth monitoring in Flanders based on height at the start of GH therapy in children with growth hormone deficiency and Turner syndrome

Klink Daniel , Logghe Karl , Thomas Muriel , Roelants Mathieu , Van Hoeck Katelijne , Lysy Philippe , Becker Marianne , Staels Willem , de Schepper Jean

Background/Aims: Length and weight of all children in Flanders are monitored every three years at school from the age of 3 years. The current criteria used for referral to specialized care are: height SDS < -2.5, height SDS between -2 and -2.5 SDS with a height SDS adjusted for parental height < -1.64, or a decrease in height SDS of more than 1 SDS in the past 3 years. The aim of this study is to investigate the sensitivity of the Flemish referral criter...

Mosaic sex chromosomal abnormalities in male individuals with short stature: a new role for non-conventional techniques (whole exome sequencing, genome wide array analysis, SHOX MLPA) in making the genetic diagnosis

Westra D. , Rinne T.K. , Oud M.S. , Ruiterkamp-Versteeg M.H.A. , de Leeuw N. , van der Velden A.A.E.M. , Kempers M.J.E.

The phenotype in male individuals with a mosaic sex chromosomal abnormality is heterogenous, but ambiguous genitalia, delayed puberty, disturbed spermatogenesis, and short stature are frequently seen. Genetic investigation in boys with idiopathic/isolated short stature usually includes SHOX gene analysis (sequencing and copy number detection by MLPA), genome wide array analysis, and/or whole exome sequencing (WES). In the Netherlands, conventional karyotyping is not part of th...
