Pediatric Patients with Congenital Adrenal Hyperplasia have Unfavorable Changes in their Cardiovascular Risk Profile

Mooij Christiaan F. , van Herwaarden Antonius E. , Roeleveld Nel , de Korte Chris L. , Kapusta Livia , Claahsen - van der Grinten Hedi L.

Background: Patients with congenital adrenal hyperplasia (CAH) are at risk of developing an unfavorable cardiovascular risk (CVR) profile. Data on the CVR profile in pediatric CAH patients are scarce.Objective and hypotheses: To evaluate the CVR profile of pediatric CAH patients.Method: A cross-sectional study in CAH patients (8–16 years) was performed (n=27). Blood was taken to evaluate several circulating CVR marker...

Determinants of Advanced Bone Age in Childhood Obesity

Jan de Groot Cornelis , van den Berg Adriaan , Ballieux Bart , Kroon Herman , Rings Edmond , Maarten Wit Jan , van den Akker Erica

Background: Childhood obesity is associated with advanced bone age (BA), leading to an altered growth pattern. Previous results of studies suggest that androgens, estrogens, sex hormone binding globulin (SHBG) and insulin are responsible for this phenomenon, but results are contradictory and might be biased by confounders.Objective and hypotheses: To investigate the independent effects of estrogens, androgens, SHBG and insulin parameters on BA advancemen...

The Diverse Phenotype of Mutations in T3 Receptor Alpha (TRα)

van Gucht Anja , Demir Korcan , Zwaveling Nitash , Wennink Hanneke , Buyukinan Muammer , Catli Gonul , Dundar Bumin Nuri , Meima Marcel , Visser Edward , van Trotsenburg Paul , Visser Theo , Peeters Robin

Background: Recently, the first patients with resistance to thyroid hormone (RTHα) due to inactivating mutations in TRα1 have been identified. These patients are characterized by growth retardation, delayed bone development, mild cognitive defects, delayed motor development and abnormal thyroid function tests.Objective and hypotheses: We hypothesized that the phenotype of a TRα mutation depends on its location, e.g. if it is present only i...

Adrenal Steroid Precursors Accumulating in Congenital Adrenal Hyperplasia lead to Transactivation of the Glucocorticoid Receptor

Pijnenburg-Kleizen Karijn , Engels Manon , Mooij Christiaan , Griffin Aliesha , Krone Nils , Span Paul , van Herwaarden Antonius , Sweep Fred , Claahsen-van der Grinten Hedi

Background: Congenital adrenal hyperplasia (CAH) patients are clinically often less severely affected by cortisol deficiency than anticipated from their enzymatic defect.Objective and hypotheses: We hypothesize that adrenal steroid hormone precursors that accumulate in untreated or poorly controlled CAH have glucocorticoid activity and partially compensate for cortisol deficiency. We aimed to determine the in vitro binding, translocation and tra...

Cardiovascular risk profile in adult patients with congenital adrenal hyperplasia: a cross-sectional study

van der Zwan Y.G. , Schrӧder M. , Stikkelbroeck N.M.M.L. , Reisch N. , Falhammar H. , Roeleveld N. , Claahsen-van der Grinten H.L.

Background: Adults with congenital adrenal hyperplasia due to 21-hydroxylase deficiency (21OHD) develop an adverse metabolic and cardiovascular risk profile. Both over- and undertreatment with glucocorticoids are associated with these adverse metabolic effects. There is limited data available of changes in cardiovascular parameters during lifetime.Objective: This study aimed to evaluate unfavorable changes in cardiovascu...

Effects of tiratricol treatment withdrawal in MCT8 deficiency: ReTRIACt Trial

Freund Matthijs , Chatterjee Krishna , van Geest Ferdy , van der Most Floor , Bowers Dominic , Persson Anders , J Bauer Andrew , Edward Visser W.

We introduce the ReTRIACt Trial (NCT05579327) of tiratricol (Triac) for MCT8-deficiency, a rare X-linked disease resulting from disordered thyroid hormone transport and characterized by profound neurodevelopmental delay and features of chronic peripheral thyrotoxicosis. The ReTRIACt Trial aims to verify the effects of tiratricol observed in previous studies. It is a double-blind, randomized, multicenter, placebo-controlled study to evaluate the effects of tiratricol discontinu...

Exploring the Long-Term Consequences of Congenital Adrenal Hyperplasia: First Study of Testicular Adrenal Rest Tumors Profile in Indonesia

Angelina Chandra Epifani , Utari Agustini , P.H. Adriaansen Bas , Westra Dineke , Hendara Ningrum Farah , Eduard van Herwaarden Antonius , L. Claahsen-van der Grinten Hedi

Background: Late identification of male patients with congenital adrenal hyperplasia (CAH) due to 21 hydroxylase deficiency (21OHD) can increase the risk of developing a benign tumor near the mediastinum testes called testicular adrenal rest tumors (TART), that can cause infertility. However, these long-term consequences of 21OHD have not yet been studied in Indonesia.Objective: This study aims to elucidate the prevalenc...

Hormonal markers of ovarian function and the role in predicting reproductive lifespan in girls with Turner syndrome

van der Coelen Sanne , Sas Theo , Richter-Unruh Annette , Peek Ron , Braat Didi , Fleischer Kathrin , IntHout Joanna , van der Velden Janielle

Introduction: Turner syndrome (TS) significantly impacts the reproductive lifespan of affected girls due to premature ovarian insufficiency (POI). To improve fertility counseling for (parents of) girls with TS, it is important to predict the ovarian reserve at an early age. However, this is challenging since data on longitudinal hormone parameters related to ovarian function are scarce. This study aims to initiate a first step towards a prediction model for ov...

Neonatal TSH screening for congenital hypothyroidism: before discharge or at home?

Boros Emese , Marcelis Lionel , Van Vliet Guy , Elilie Mawa Ongoth Farel , Heinrichs Claudine , Brachet Cecile

In Belgium, neonatal TSH screening for congenital hypothyroidism has been performed between day 3 and 5 of life since the late seventies. In January 2015, a policy of early discharge of healthy neonates was implemented so that the neonatal screening strategy had to be adapted. Between January 2015 and September 2019, dried blood spot sampling was mostly collected at home AFTER discharge at 72 h of life (Newborn Screening Strategy 1 (NBS1)). After October 2019, sampling was mos...
