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

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...

Results of Exome Sequencing in Disorders of Sex Development

Kempers Marlies , Claahsen Hedi , Alfen Janielle van , Velden van der , Rinne Tuula

Disorders or Differences of sex development (DSD) are a heterogeneous group of congenital conditions, involving variations of chromosomal, gonadal, or anatomical development. Diagnosis is based on clinical, biochemical, imaging and genetic evaluation. In recent years knowledge about genetic causes has increased, mainly due to improved genetic techniques. In this study we investigated the yield of exome sequencing in our patients with DSD. Patients and methods: Genetic i...

Introduction: Classic congenital adrenal hyperplasia (CAH) caused by 21-hydroxylase deficiency results in impaired synthesis of gluco- and often also of mineralocorticoids. Early treatment with glucocorticoids and mineralocorticoids prevents life-threatening crises. In some centres, additional salt is prescribed in the first year. However, until now the use of salt is controversial and not proved to result in better outcome in studies.<s...

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...

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...

Background: Following the 2010 CAH consensus, the need for genetic confirmation of diagnosis remains uncertain and variation in practice is unclear.Methods: This variation was assessed by using the International CAH(I-CAH) Registry which was developed using the same platform as the I-DSD Registry.Results: After the development of the I-CAH Registry in October 2014, the rate of addition of CAH cases increased from 2/month to 14/mont...

Introduction: Congenital adrenal hyperplasia (CAH) is the most common genetic condition in the spectrum of differences of sex development (DSD). Surgery in DSD is a controversial topic and there is no consensus if to perform surgery, how to perform surgery, and when to perform surgery. The current study was designed to evaluate the current practice in CAH related surgical practice in girls.Patients and Methods: All cases...

Introduction: Despite existing guidelines there is no unified approach to glucocorticoid and mineralocorticoid replacement in congenital adrenal hyperplasia (CAH). Consequently, treatment varies in adults and children as well as across countries.Objective: We used data from the I-CAH Registry to identify geographical and temporal variations in the treatment with glucocorticoids and mineralocorticoids of children and adul...
