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...

Background: Current guidelines for girls with gonadal dysgenesis due to Turner Syndrome (TS) recommend initiating estrogen therapy at 11-12 years of age, using 'natural' 17-β estradiol. However, there is scant evidence regarding the optimal modality of induction, particularly concerning whether oral or transdermal routes are more effective or acceptable.Aim: To retrospectively evaluate differences in puber...

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 ...

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...

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...

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...

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...

Context: Children with 21-hydroxylase deficiency (21OHD) require chronic glucocorticoid administration to substitute glucocorticoids and suppress adrenocorticotropic hormone-induced hyperandrogenemia. There is still no evidence about the best timing of the highest hydrocortisone (HC) dose. Administration of the highest dose in the morning aims to mimic the physiological rhythm of cortisol, while a high dose late in the evening may inhibit the early-morning inc...

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...
