Patients with Non Classic 21-OH Deficiency typically show 60-min stimulated 17-OHP values between 1,500 and 10,000 ng/dl. This chart
shows how the 17-OHP values cluster at three areas for normal (below
1,500), Non-Classical CAH (1500-10,000) and, and Classical CAH (above
10,000).(6) A useful chart showing the CAH testing algorithm is available.(7)
Genetic Testing for 21-OH Deficiency
Genetic
testing is now available and very useful. This Quest Lab test shows
whether or not there is a mutation in the CYP21A2 gene coding for the
21-Hydroxylase Enzyme.(8) The CAHDtex test by Esoterix is also useful in showing the exact mutation in the CYP21A2 gene.(9) Once the exact mutation in the CYP21A2 gene is known, refer to this chart to determine the severity of the enzyme defect.(10)
Genetic testing of other family members is usually recommended once a
sibling is found with the mutation. Dr. Maria New has her own in-house
lab in New York which does genetic testing for CAH.(11)
Clinical Presentation in Children
In
children, the signs of non-classical CAH include premature onset of
puberty, cystic acne, accelerated growth, and advanced bone
age. Premature development of pubic hair may occur as early as 6 months
of age (due to elevated testosterone). The severe cystic acne may be
unresponsive to oral antibiotics and retinoic acid (Accutane). Although
the child may be taller than the other kids in early childhood, this
early growth spurt finishes early (because of epiphyseal fusion),
and final height ends up shorter than usual. Thus, these kids are tall
children but short adults. Another feature may be male pattern baldness
in a female involving the top of the head and sparing the sides.
Teenagers and Young Adults - Major Cause of Infertility
Teenage
girls may present with features of elevated testosterone such as facial
hair (hirsutism), acne and menstrual irregularities or anovulation.
Young adult females may present with the chief complaint of infertility.
It has been generally recognized that infertility of undetermined cause
in women may be reversed with glucocorticoid (cortef or prednisone)
therapy, which most likely treats an occult Non-Classical CAH Syndrome.
William Mc Jefferies MD successfully treated thousands of such cases
describerd in his 1976 medical classic, The Safe Uses of Cortisol.(12)
Dr. McJefferies speculated correctly that an abnormality in adrenal
steroid synthesis was present in many young girls with infertility, and
only years later was the exact molecular and genetic basis elucidated.
In retrospect, non-classical CAH should be called McJefferies syndrome
to give this great clinician credit for his early work.
Treatment of Non Classical CAH with Cortisol Restores Fertility
Oral
tablets containing low dose cortisol successfully treat Non-Classical
CAH and reverse the symptoms restoring fertility. The cortisol
suppresses ACTH and reduces the testosterone production by the adrenal.
Dr. Maria I New is
the present day national expert on non-classical CAH, and she has
followed a large group of 400 patients with Non-Classical CAH. Dr. New
treats them with 0.25 mg. dexamethasone at the hour of sleep, and notes
that it takes about 3 months for reversal of acne and
infertility. Hirsutism takes longer to respond, about 30 months. (3)(13)

The
cost for a dexamethasone tablet is $0.50, and the 3-month treatment
cost is estimated to be $45. Compare this $45 dollars to the infertility
treatment cost of $30,000 for one cycle of in vitro fertilization. Dr.
Maria New says that many patients presenting with infertility actually
have NonClassical CAH, and fertility could be restored
easily with treatment with oral cortisol tablets such as
Dexamethasone, Prednisone or even the Cortef recommended by
McJefferies.(3)
Before spending a fortune on in-vitro fertilization for infertility, it
would be prudent to rule out Non-Classical CAH with a simple genetic
test.
Safety of Low Dose Cortisol
Low
dose Cortef, Prednisone or Dexamethasone treatment is safe without the
adverse side effects associated with high dose treatment. However,
there is a chance of mild adrenal suppression which could require
additional or extra doses of medication under periods of higher stress
or illness such as the flu or when undergoing a surgical operation.
Therefore McJefferies routinely gave instructions to increase the
cortisol dosage when a flu illness is noted coming on or under similar
stresses. He also advised his patients to wear a warning bracelet
containing the information that the patient has non classical CAH, with
cortisol dosage and timing.(12)

TESTING FOR 21-HYDROXYLASE DEFICIENCY. Esoterix introduces a new DNA
test to identify deficiency in the 21-hydroxylase gene, the most common
cause of congenital adrenal hyperplasia (CAH). CAHDetx
evaluates the CYP21 gene, detecting mutations and gene
deletion/conversions that account for approximately 90% to 95% of all
CAH cases.
