The Circadian Rhythm of Cortisol Binding Globulin has Little Impact on Cortisol Exposure after Hydrocortisone Dosing

Melin Johanna , Hartung Niklas , Parra-Guillen Zinnia , Whitaker Martin , Ross Richard , Kloft Charlotte

Background: Optimisation of hydrocortisone replacement therapy remains challenging due to complex pharmacokinetics as circulating cortisol is protein bound mainly to corticosteroid-binding globulin (CBG) that has a circadian rhythm.Objective: A detailed analysis of the CBG circadian rhythm and its impact on cortisol exposure during hydrocortisone replacement therapy.Methods: CBG was measured over 24 h in 14 healthy...

Rationale for a reduced dexamethasone dose in prenatal congenital adrenal hyperplasia therapy based on pharmacokinetic modelling

Neumann Uta , Stachanow Viktoria , Blankenstein Oliver , Fuhr Uwe , Huisinga Wilhelm , Reisch Nicole , Kloft Charlotte

Context: Prenatal dexamethasone (Dex) therapy is used in female foetuses with congenital adrenal hyperplasia (CAH) to suppress adrenal androgen excess and prevent virilisation of the external genitalia. The prenatal dexamethasone dose of 20 µg/kg/d has been used for decades in prenatal CAH. Despite the risks for the treated mother and potentially for the unborn child, no clinical study or evaluation had been conducted in order to determine a Dex dose with a scientific rat...

Predict – A randomized investigation of a reduced prenatal dexamethasone dose to reduce virilization in female fetuses with congenital adrenal hyperplasia

Neumann Uta , Stachanow Viktoria , Kloft Charlotte , Blankenstein Oliver , Lajic Svetlana , Reisch Nicole

Introduction: Prenatal dexamethasone (Dex) therapy in female fetuses with congenital adrenal hyperplasia (CAH) has been conducted for 40 years but the dose given to the pregnant woman has never been fully evaluated in a randomized clinical trial. Prenatal Dex therapy is associated with potential side effects for both mother and child.Methods: In a study funded by the German Federal Ministry of Education and Research (BMB...
