N2 - Introduction: Congenital adrenal hyperplasia (CAH) is an autosomal recessive disease predominantly caused by 21-hydroxylase deficiency. Clinical management in children includes glucocorticoid and often mineralocorticoid treatment alongside monitoring outcomes such as an-Thro-po-metry, pubertal status, blood pressure, and biochemistry. Objective: The objective of this pilot study was to present the use of 17-hydroxyprogesterone (17-OHP) and androgen metabolites expressed as standard deviation (SD) scores rather than actual concentrations as a tool in the management of children with CAH as well as in research settings. Methods: The study was a retrospective, longitudinal study that took place in a single, tertiary center and included 38 children and adolescents aged 3-18 years with CAH due to 21-hydroxylase deficiency. Biochemical measurements of 17-OHP, androstenedione, dehydroepiandrosterone-sulphate (DHEAS), and testosterone using liquid chromatography-Tandem mass spectrometry were expressed as SD scores, and outcomes such as genotype, height, bone maturation, blood pressure, and treatment doses were extracted from patient files. Results: The majority (86%) of CAH patients had 17-OHP measurements above +2 SD during standard hydrocortisone therapy, receiving an average daily hydrocortisone dose of 12.6 mg/m2. Androstenedione concentrations were mostly within ±2 SD, whereas DHEAS values were below-2 SD in 47% of patients. Conclusions: Applying sex-and age-related SD scores to 17-OHP and androgen metabolite concentrations allows for monitoring of hydrocortisone treatment independent of age, sex, assay, and center. We propose that 17-OHP and androgen metabolites expressed as SD scores be implemented as a unifying tool that simplifies research and, in the future, also optimal management of treatment.
