Delayed Diagnosis of Salt Wasting Congenital Adrenal Hyperplasia, without Complications of Cortisol Deficiency: A Case Report

Pijnenburg-Kleizen Karijn , Noordam Kees , Otten Barto , Claahsen-van der Grinten Hedi

Background: In salt wasting congenital adrenal hyperplasia (SW-CAH) patients suffer from a deficiency of both cortisol and aldosterone and develop life-threatening salt wasting crises neonatally. Treatment consists of glucocorticoids, mineralocorticoids and salt supplementation. We present a case with a two years delayed diagnosis of SW-CAH.Case presentation: The patient was admitted to the hospital at the age of two weeks because of poor feeding, irrita...

Personalized Health Care: Home POCT Sodium Measurement in Diabetes Insipidus Centralis in a Patient with Impaired Thirst Perception

van der Linde Annelieke , van Herwaarden Teun , de Grouw Elke , Claahsen - van der Grinten Hedi

Background: Central diabetes insipidus (CDI) is caused by deficiency of antidiuretic hormone (ADH). Patients with CDI are at risk for fluid balance disturbances, especially when there is impaired thirst perception or inability to access water freely. Serum sodium measurement gives a good reflection of the actual fluid balance but is generally not available in the home situation. For patients in which CDI is difficult to manage sodium measurement at home may be a good instrumen...

An adolescent with Hypertension Caused by Primary Hyperaldosteronism due to KCNJ5 Mutation

van der Linde Annelieke , Deinum Jaap , Konijnenberg Yvette , Keijzer-Veen Mandy , Claahsen-van der Grinten Hedi

Background: Primary aldosteronism (PA) is a rare form of secondary hypertension. In adults PA is often caused by unilateral adrenal adenoma which can be cured by unilateral adrenalectomy. However, in young patients hereditary causes of PA have to be considered with bilaterally affected adrenal glands.Objective and hypotheses: We report on an adolescent with PA due to a recently described KCNJ5 mutation and want to point out the importance of performing m...

Molecular Characterization of Testicular Adrenal Rest Tumours in Congenital Adrenal Hyperplasia; Lesions with both Adrenocortical and Leydig Cell Features

Smeets Evelien , Span Paul , van Herwaarden Antonius , Wevers Ron , Sweep Fred , Claahsen-van der Grinten Hedi

Background: Characterization of testicular adrenal rest tumours (TART) are one of the major long-term complications in congenital adrenal hyperplasia (CAH) patients. Although several adrenal-like properties have been assigned to these benign lesions, the exact etiology has not been established yet.Objective and Hypotheses: The aim of this study was to analyze several (steroidogenic) characteristics of TART tissue which may be classified as adrenal cortex...

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...

Endocrine Abnormalities in Phosphoglucomutase 1 Deficiency

Mueksch Barbara , Morava Eva , Lefeber Dirk , Claahsen-van der Grinten Hedi , Korsch Eckhard

Introduction: Phosphoglucomutase 1 catalyzes the interconversion of glucose-6-phosphate and glucose-1-phosphate. Phosphoglucomutase 1 deficiency (PGM1-CDG), previously termed glycogenosis type XIV (OMIM 612934), is a rare variant of the congenital disorders of glycolysation (CDG), resulting in abnormal attachment and processing of protein linked N-glycans. We present a girl with PGM1-CDG and delayed pubertal development and review the endocrine findings of the few pat...

Growth-Related Characteristics of Patients <18 Years of Age with Congenital Adrenal Hyperplasia Due to 21-Hydroxylase Deficiency (21OHD): Real-World Evidence from the I-CAH Registry

Farrar Mallory , He Wei , Ali Salma R , Bryce Jillian , Lawrence Neil , Baronio Federico , Claahsen-van der Grinten Hedi L. , Bonfig Walter , Krone Nils , Yonan Chuck , Ahmed S. Faisal ,

Background: Classic congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is a rare autosomal recessive condition characterized by cortisol deficiency and elevated ACTH secretion, resulting in excess androgen production. This exposure to excess androgens contributes to advanced skeletal maturation and reduced growth in puberty. Data from the I-CAH registry were analyzed to identify growth-related characteristics of children and adolescents with...

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...

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...

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...
