Following the introduction of life-saving glucocorticoid replacement 60 years ago, congenital adrenal hyperplasia (CAH) has evolved from being perceived as a paediatric disorder to being recognized as a lifelong, chronic condition affecting patients of all age groups. Increasing evidence suggests that patients with CAH have an increased risk to develop health problems during adult life, with si...

Congenital adrenal hyperplasia (CAH) is the most frequently encountered genetic steroid disorder affecting fertility. Steroid hormones play a crucial role in sexual development and reproductive function; patients with either 21- hydroxylase or 11β-hydroxylase deficiency thus face immense challenges to their fertility. Given the relevance of CAH in reproductive medicine as well as the diagnostic...

The main aim of the chapter entitled Management Approaches to Congenital Adrenal Hyperplasia (CAH) in Adolescents and Adults; Latest Therapeutic Developments, will be first to familiarize readers with current treatment guidelines using glucocorticoid and mineralocorticoid replacement in treating this common and under-diagnosed cause of amenorrhea. Next, to introduce readers to the concept of in...

Congenital adrenal hyperplasia (CAH) is a genetic autosomal recessive condition most frequently as a result of a mutation in the 21-hydroxylase enzyme gene. Patients with poorly controlled CAH can manifest characteristic imaging findings as a result of adrenocorticotrophic hormone stimulation or the effects of cortisol precursor excess on various target organs. We present a spectrum of imaging ...

Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency results in excess androgen production which can lead to early epiphyseal fusion and short stature. Prader-Willi syndrome (PWS) is a genetic disorder resulting from a defect on chromosome 15 due to paternal deletion, maternal uniparental disomy, or imprinting defect. Ninety percent of patients with PWS have short stature. In t...

The standard method of primary neonatal screening for congenital adrenal hyperlasia (CAH), determination of 17-hydroxyprogesterone (17OHP) in heelprick blood, is the object of recurrent controversy because of its poor diagnostic and economic efficiency. The superior ability of urinary pregnanetriolone levels to discriminate between infants with and without classical CAH has been known for some ...

Congenital adrenal hyperplasia (CAH) is a group of hereditary diseases, which are autosomal recessive. CAH occurs due to defect in one of the cortisol coding genes and often clinically presents itself with signs of androgen overproduction. In this article, we report a case of CAH and Schmid metaphyseal dysplasia. Our literature review indicated that this report is the first attempt on CYP11B1 a...

Oxime-directed catalytic asymmetric hydroboration is diverted to catalytic asymmetric hydrogenation (CAH) upon the addition of a proton source, such as MeOH, or by running the reaction under a hydrogen atmosphere. A borane (e.g., pinacolborane) is required to promote CAH. Tri- and tetrasubstituted alkenes, including the challenging all-alkyl tetrasubstituted alkenes, undergo CAH with enantiomer...

CONTEXT Treatment of congenital adrenal hyperplasia (CAH) is suboptimal. Inadequate suppression of androgens and glucocorticoid excess are common and current glucocorticoid formulations cannot replace the cortisol circadian rhythm. OBJECTIVES The primary objective was to characterize the pharmacokinetic profile of Chronocort, a modified-release hydrocortisone formulation, in adults with CAH. ...
