Lipoid congenital adrenal hyperplasia

Lipoid congenital adrenal hyperplasia results from defects in the steps from cholesterol to pregnenolone. The adrenals are large and filled with lipid globules derived from cholesterol. Life-threatening mineralocorticoid and glucocorticoid deficiency becomes apparent in infancy or early childhood. Sex steroid production is greatly impaired. XY infants (genetic males) are severely undervirilized so that the external genitalia at birth are female (normal or slightly virilized). XX infants have normal female anatomy and if their mineralocortico ...

Problems caused to persons with lipoid CAH can be divided into (1) mineralocorticoid deficiency, (2) glucocorticoid deficiency, (3) sex steroid deficiency, and (4) damage to gonads caused by lipid accumulation. Lipoid congenital adrenal hyperplasia - Mineralocorticoid deficiency. Most infants born with lipoid CAH have had genitalia female enough that no disease was suspected at birth. Because the adrenal zona glomerosa is undifferentiated and inactive before delivery, it is undamaged at birth ...

The most common abnormal alleles of this condition impair both the 17α-hydroxylase activity and the 17,20-lyase activity. Like other forms of CAH, 17α-hydroxylase deficiency impairs the efficiency of cortisol synthesis, resulting in high levels of ACTH secretion and hyperplasia of the adrenal glands. Clinical effects of this condition include overproduction of mineralocorticoids and deficiency of prenatal and pubertal sex steroids. Congenital adrenal ...

11β-OH CAH resembles 21-hydroxylase deficient CAH in its androgenic manifestations: partial virilization and ambiguous genitalia of genetically female infants, childhood virilization of both sexes, and rarer cases of virilization or infertility of adolescent and adult women. The mineralocorticoid effect differs: hypertension is usually the clinical clue that a patient has 11- rather than 21-hydroxylase CAH. Diagnosis of 11β-OH CAH is usually confirmed by demonstration of marked elevations of 11-deoxycortisol and 11-deoxycorticosterone (DOC ...

The sex steroid consequences of severe 3β-HSD CAH are unique among the congenital adrenal hyperplasias: it is the only form of CAH that can produce ambiguity in both sexes. As with 21-hydroxylase deficient CAH, the degree of severity can determine the magnitude of over- or undervirilization. In an XX (genetically female) fetus, elevated amounts of DHEA can produce moderate virilization by conversion in the liver to testosterone. Virilization of genetic females is partial, often mild, and rarely raises assignment questions. The issues ...

Congenital adrenal hyperplasia (CAH) refers to any of several autosomal recessive diseases resulting from defects in steps of the synthesis of cortisol from cholesterol by the adrenal glands. All of the forms of CAH involve excessive or defective production of sex steroids and can pervert or impair development of primary or secondary sex characteristics in affected infants, children, and adults. Many also involve e ...

3β-HSD II mediates three parallel dehydrogenase/isomerase reactions in the adrenals that convert Δ4 to Δ5 steroids: 17-hydroxypregnenolone to 17OHP, DHEA to androstenedione, and pregnenolone to progesterone. 3β-HSD II also mediates an alternate route of testosterone synthesis from androstenediol in the testes. 3β-HSD deficiency results in large elevations of pregnenolone, 17-hydroxypregnenolone, and DHEA. However, complexity arises from the presence of a second 3β-HSD (3β-HSD I) coded by a different gene, expressed in the liver ...

Some of the childhood management issues are similar those of 21-hydroxylase deficiency: replacing mineralocorticoid with fludrocortisone; suppressing DHEA and replacing cortisol with glucocorticoid; providing extra glucocorticoid for stress; close monitoring and perhaps other adjunctive measures to optimize growth. deciding whether surgical repair of virilized female genitalia is warranted However, unlike 21-hydroxylase CAH, children with 3β-HSD CAH may be unable to produce adeq ...

The enzyme itself is attached to the smooth endoplasmic reticulum of the steroid-producing cells of the adrenal cortex and gonads. P450c17 functions as both a 17α-hydroxylase and a 17,20-lyase. The dual activities mediate three key transformations in cortisol and sex steroid synthesis: As 17α-hydroxylase it mediates Pregnenolone → 17-hydroxypregnenolone and Progesterone → 17-hydroxyprogesterone. As 17,20-lyase it mediates 17-hydroxypregnenolone → DHEA. An e ...

A very small number of people have reportedly had an abnormal gene that resulted primarily in a reduction of 17,20-lyase activity, rather than both the hydroxylase and lyase activities as described above. In these people the defect had the effect of an isolated impairment of sex steroid synthesis, with no significant effects on mineralocorticoid or glucocorticoid production, and no adrenal hyperplasia, mineralocorticoid overproduction, or hypertension. The sex steroid deficiency produces effects similar to 17α-hydroxylase deficiency. ...

Hypertension and mineralocorticoid excess is treated with glucocorticoid replacement, as in other forms of CAH. Most genetic females with both forms of the deficiency will need replacement estrogen to induce puberty. Most will also need periodic progestin to regularize menses. Fertility is usually reduced because egg maturation and ovulation is poorly supported by the reduced intra-ovarian steroid production. The most difficult management decisions are posed by the more ambiguous genetic (XY) males. Most who are severely underv ...

The gene for the cytochrome P450c17 enzyme resides on chromosome 10q24.3. Mutations of this gene result in altered activities of the enzyme and the various forms of congenital adrenal hyperplasia and sex steroid deficiency due to its impairment. As are most enzyme deficiencies, these disorders are inherited in an autosomal recessive manner with a reported incidence of about 1 in 50,000 births. The OMIM number for diseases arising from mutations of this gene is 202110. ...

Cortisol is an adrenal steroid hormone necessary for life; production begins in the second month of fetal life. Inefficient cortisol production results in rising levels of ACTH, which in turn induces overgrowth (hyperplasia) and overactivity of the steroid-producing cells of the adrenal cortex. The defects causing adrenal hyperplasia are congenital (i.e., present at birth). Cortisol deficiency in CAH is usually partial, and not the most serious problem for an affected person. Synthesis of cortisol shares steps with synth ...
