Cardiac Function in Pediatric Patients with Congenital Adrenal Hyperplasia

Mooij Christiaan F. , Pourier Milanthy S. , Weijers Gert , de Korte Chris L. , Claahsen - van der Grinten Hedi L. , Kapusta Livia

Background: Congenital adrenal hyperplasia (CAH) is characterized by cortisol deficiency and hyperandrogenism. Both hyperandrogenism and treatment with supraphysiological doses of glucocorticoids may cause unfavorable changes in the cardiovascular risk profile of CAH patients. Data on the cardiac function in CAH patients is scarce.Objective and hypotheses: To evaluate the cardiac function in pediatric CAH patients.Method: The cardi...

GATA Transcription Factors in Testicular Adrenal Rest Tumours

Engels Manon , Span Paul , van Herwaarden Teun , Hulsbergen-van de Kaa Christina , Sweep Fred , Claahsen-van der Grinten Hedi

Background: Testicular Adrenal Rest Tumours (TARTs) are benign tumours that frequently occur in male patients with congenital adrenal hyperplasia. They exhibit both testicular and adrenal characteristics, but their aetiology is unknown. Additionally, TART resembles Leydig cell tumours (LCTs), while no marker exist to discriminate between these testis tumours. GATA transcription factors play an important role in eukaryotic development and are expressed in foetal and adult adren...

MEN1 Syndrome Because of Combined Germline and Somatic Mosaicism, with Important Consequences for Relatives

Kempers Marlies , Stikkelbroeck Nike , Mensenkamp Arjen , Pfundt Rolph , van der Luijt Rob , Timmers Henri , Claahsen Hedi , Hoogerbrugge Nicoline , Hermus Ad

Background: Multiple endocrine neoplasia type I (MEN1) is characterized by the combined occurrence of tumours in several endocrine tissues such as parathyroid tumours, pituitary tumours (usually prolactinomas) and pancreatic neuroendocrine tumours. MEN1 is an autosomal dominant disorder caused by germline mutations in the tumour suppressor gene MEN1. First-degree relatives of a germline MEN1 mutation carrier have a 50% risk of the mutation. Intensive surveillance of g...

Conservative Treatment Allows Substantial Improvement of Neonatal Cushing Syndrome in McCune Albright Syndrome, a 2 Year Follow-up

van Nieuwaal Nancy HG , Houwen Roderick H J , van der Grinten Hedi L Claahsen , Stuart Annemarie A Verrijn

Background: McCune Albright syndrome (MAS) is defined by the classic triad of precocious puberty, fibrous dysplasia of bone and café au lait skin pigmentation. However, the clinical spectrum is often more variable due to mosaic distribution of the postzygotic GNAS-mutation. Hypercortisolism occurs in a minority (5%) of patients. It is most frequently caused by nodular adrenal hyperplasia and can be life-threatening. Decisions on whether clinical management should be conse...

Keywords: Congenital Adrenal Hyperplasia, Parent’s experience, Focus Group DiscussionBackground: Congenital Adrenal Hyperplasia (CAH) leads to many unseen social burdens for parents, including ambiguous genitalia (in girls), lifelong use of medication, including stress dosing, social and psychological pressure, and stigmatization. This study aimed to investigate various lived experiences of parents caring for their...

Elevated Concentrations of Adrenal Steroid Precursors with Glucocorticoid Activity Might Prevent Addisonian Crisis in Untreated Patients with Classic Congenital Adrenal Hyperplasia

Engels Manon , Pijnenburg-Kleizen Karijn , Utari Agustini , Faradz Sultana , Heuvel Joop , Herwaarden Teun van , Span Paul , Sweep Fred , Grinten Hedi Claahsen-van der

Introduction: Congenital adrenal hyperplasia (CAH) is most often caused by 21-hydroxylase deficiency (21OHD: 95%) or by 11-hydroxylase deficiency (11OHD). Classic CAH results in impaired cortisol production and consequently elevated ACTH concentrations leading to chronic adrenal stimulation with strongly elevated adrenal steroid precursors before the enzymatic defect. In contrast to other forms of adrenal insufficiency, some untreated classic CAH patients seem to have less cli...

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...

The Role of the Nurse Practitioner in Optimising Care for Children with Congenital Adrenal Hyperplasia

van de Crommert Viviane , van Alfen-van der Velden Janielle , van der Linde Annelieke , Noordam Kees , Claahsen-van der Grinten Hedi

Background: Congenital Adrenal Hyperplasia (CAH) is a rare group of congenital adrenal diseases with an estimated prevalence of about ten newly diagnosed patients in the Netherlands per year. Morbidity and mortality improved significantly in the last 20 years mainly due to improvement of multidisciplinary care and education of patients and parents. In the last years the role of the nurse practitioner (NP) as case manager in the care and follow up of patients with chronic disea...

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...
