Congenital adrenal hyperplasia, also known as 21-hydroxylase deficiency or adrenogenital syndrome, is an inherited disorder of the adrenal glands. It can be difficult to diagnose and treatment needs to be individualized to suit each person. The authors detail a successful treatment which can be done by tailoring the dose of hydrocortisone to suit the patient using 24 hour cortisol and 17 OHP profiles. Congenital Adrenal Hyperplasia addresses how hydrocortisone works, what can go wrong, how to correct it, and explains that the timing of doses is extremely important as is measuring the cortisol attained from a dose. Congenital Adrenal Hyperplasia provides an in-depth analysis of this disorder for pediatric endocrinologists as well as primary care providers to provide affected patients with an updated model of care and appropriate treatment. Patients and family members will benefit from the trend-forward information presented and will be empowered to approach their health care providers with the expectation of receiving individualized care and treatment of the disorder.
