WebApr 11, 2024 · How is congenital adrenal hyperplasia managed? Acute management is based on fluid management and the treatment of hypoglycaemia. These patients will require lifelong steroid replacement. Hydrocortisone is least likely to impair growth but has a shorter duration of action than other steroids – prednisolone or dexamethasone. WebEndocrinology. Congenital adrenal hyperplasia due to 21-hydroxylase deficiency, in all its forms, accounts for over 95% of diagnosed cases of congenital adrenal hyperplasia (CAH), [1] and CAH in most contexts refers to 21-hydroxylase deficiency and different mutations related to enzyme impairment have been mapped on protein structure.

DOI： 10.1210/jc.2024-01865 . WebThe concept of disordered steroidogenesis in other forms of CAH is the same as in 21OHD: high steroids above the block in the steroid pathway, low steroids below the block, and increased flux around the block. In 17OHD, a block orthogonal to that in 21OHD causes mineralocorticoid excess and loss of androgen (and estrogen) synthesis.
