Congenital adrenal hyperplasia (CAH) is caused by a deficiency of one of the enzymes required for cortisol biosynthesis. The disease is classified as either classic (severe phenotype), subdivided into simple-virilizing (SV) and salt-wasting (SW), or non-classic (NC) CAH. The treatment regime involves life-long glucocorticoid replacement, especially in classic phenotype.We aimed to assess medication adherence, endocrine knowledge, and self-management in patients with CAH and to compare patients’ and physicians’ assessments of medication adherence.A prospective cross-sectional study of 108 patients with CAH (52 children and 56 adults) and 45 parents/caregivers. Two adherence measures were used, a self-reported questionnaire named Adherence Starts with Knowledge (ASK-12) with a cut-off level >22 defined as poor adherence rate, and an assessment by a physician based on growth-rate, 17-hydroxyprogesterone profile, and medical history, ranked using a five-point Likert scale. Measurements of the patients’/parents’ knowledge and self-management were performed using Endocrine Society Clinical Practice Guidelines.Self-reported medication adherence was good with 74% of the participants reported good adherence with higher adherence in patients with the SW form. The highest endocrine knowledge and self-management were found in parents compared with children and adults with classic CAH. There was 30% discordance between the assessments by a physician and the self-reported ASK-12 scores independent of the severity of CAH.Patients and endocrinologists reported high medication adherence, however, discordance was found in 30% of the studied patients. Patients with the more severe form of CAH had higher adherence rates and demonstrated good endocrine knowledge/self-management.
