Aldosterone hypersecretion in "non-salt-losing" congenital adrenal hyperplasia. Bartter FC, Henkin RI, Bryan GT. Patients with the "non-salt-losing" form of the adrenogenital syndrome were studied before and after suppression of adrenal cortical activity with carbohydrate-active steroids. The response of aldosterone secretion to sodium deprivation

▫. In its most severe form, the adrenals make almost no cortisol or aldosterone. This is called “salt-wasting. CAH” . ▫. Both salt-wasting and simple-virilizing CAH patients may develop an ''adrenal crisis'' during periods of physical stress (illness, surgery or trauma). This is a life-   Salt Loss.

The response of aldosterone secretion to sodium deprivation was measured; in some patients response to adrenocorticotropic hormone (ACTH) was measured as well. secondary amenorrhea diagnosed as congenital adrenal hyperplasia without salt losing discovered 1 year back. Patient had menarche at age of 13 years once, very little amount of blood and did not come again since the age of menarche.

Congenital adrenal hyperplasia due to 21-hydroxylase deficiency in all its forms, accounts for over 95% of diagnosed cases of congenital adrenal hyperplasia (CAH), and CAH in most contexts refers to 21-hydroxylase deficiency and different mutations related to enzyme impairment have been mapped on protein structure.

Salt losing congenital adrenal hyperplasia

Cortisol and aldosterone replacement prevents salt-losing crisis and decreases the buildup of adrenal androgens. Lifelong hormone replacement is necessary. Semantic Scholar extracted view of "Salt-Losing Congenital Adrenal Hyperplasia (Continued)" by J. Cohen We conclude that salt‐losing congenital adrenal hyperplasia can lead to hyperkalemic distal renal tubular acidosis in early infancy. The defective renal secretion of hydrogen ion and potassium is probably related to the abolishment of the negative potential difference in the cortical collecting tubule induced by the impaired reabsorption of sodium. 21-hydroxylase deficiency is one of a group of disorders known as congenital adrenal hyperplasias that impair hormone production and disrupt sexual development. 21-hydroxylase deficiency is responsible for about 95 percent of all cases of congenital adrenal hyperplasia.

She was treated with hydrocortisone, 20 mg in the morning and 10 mg at bedtime, and fludrocortisone, 50 mcg daily. 21-hydroxylase deficiency (> 90% of congenital adrenal hyperplasia) 1 classic salt-losing type involves severe 21-hydroxylase (21 OHD) deficiency, resulting in glucocorticoid deficiency, mineralocorticoid deficiency leading to renal salt wasting, and androgen excess which may lead to prenatal virilization in infant girls In the salt-losing form of congenital adrenal hyperplasia, mineralocorticoid, usually fludrocortisone at a dose of 0.1 mg, is given to maintain normal extracellular fluid volume and electrolyte levels.

Treatment for congenital adrenal hyperplasia depends on the type of CAH you have and how severe your symptoms are. There is no cure for CAH, but many people find symptom relief with medications. Doctors prescribe several types of medications, including salt supplements and steroids, to people living with classic CAH.
