Background: Monocarboxylate-transporter 8 (MCT8) deficiency, also known as Allan-Herndon-Dudley syndrome (AHDS), is associated with severe motoric and intellectual developmental delay. The pathophysiology is characterized by central hypothyroidism (due to transporter defect) and peripheral hyperthyroidism with thyrotoxicosis. There is often an increase in the peripheral T3 values and a decrease in the T4 values. In addition, numerous comorbidities can be held ...

Background: Children with classical congenital adrenal hyperplasia (CAH) require glucocorticoid replacement. In addition to auxological examinations, laboratory measurements of e.g. 17-hydroxyprogesterone and androstenedione in serum are also necessary to assess the required dosage of hydrocortisone. Another possibility for measuring precursor steroids is hair analysis, which has not yet been carried out in children with this issue. The role of so-called 11-ox...

Background: Children with classical congenital adrenal hyperplasia (CAH) require glucocorticoid replacement. The measurement of cortisol and steroid precursors in saliva is particularly suitable for pediatric endocrinology. Data on salivary cortisol measurements in patients with CAH is limited.Objective and hypothesis: The cortisol in saliva shows a circadian rhythm even under steroid substitution. This is independent of...

Background: Central diabetes insipidus (CDI) is characterised by a central deficiency of arginine vasopressin (AVP) with polyuria and polydipsia. The etiology is heterogeneous. The treatment of choice is the oral or nasal application of DDAVP (synthetic analogue of AVP). CDI in the context of coronavirus disease 2019 (COVID19) has been reported in an individual case.Case report: We present a 9-year old male with CDI of u...

Background: Routine biochemical assessment in patients with congenital adrenal hyperplasia (CAH) includes measurement of serum 17 hydroxyprogesterone (17OHP), androstenedione (A4) and testosterone (T) and their metabolites in urine. Several studies have also described 11 oxygenated 19 carbon (11oxC19) steroids as a clinically relevant androgenetic source and highlighted their potential as markers for evaluation of adrenal androgen excess in patients with 21-hy...
