21 Hydroxylase Deficiency

A direct, rapid and highly specific fluoroimmunoassay for determining serum levels of 17-hydroxyprogesterone has been developed. It is based on the use of a sheep antiserum covalently coupled to magnetisable particles and fluorescein-labelled steroid. Sodium salicylate is employed to eliminate interference from endogenous binding proteins in serum. The sensitivity of 0·5 nmol/L is adequate for clinical purposes. Analytical recovery, linearity and precision are satisfactory and the results obtained correlate closely with those of an established radioimmunoassay using 3H-labelled steroid and the same antiserum after initial sample extraction and chromatography. The values found for serum from normal adult subjects ranged from 1·0 to 12·6 nmol/L while those from treated and untreated patients with congenital adrenal hyperplasia due to 21-hydroxylase deficiency were 1·5 to 190 and 28·0 to 655 nmol/L, respectively.

ABSTRACT The variations in plasma cortisol, testosterone and 17-hydroxyprogesterone (17-OHP) induced by an im injection of 0.25 mg cosyntrophin were studied in three groups of subjects: 16 healthy women, 16 hirsute women (HW) and 10 mild cases of congenital adrenal hyperplasia (CAH). The basal values of cortisol and testosterone were comparable between the three groups. In the patients with mild CAH, the mean 17-OHP concentration was increased: 483.9 ng/100 ml (113-1200 ng), but it should be noted that the individual values could overlap with the normal concentrations found in the controls and the HW during the luteal phase of the cycle. One hour after the injection of cosyntropin, a massive response of 17-OHP was observed in the mild cases of CAH, the mean basal concentration was multiplied by ten: 4843 ng/100 ml. The minimum concentration reached was 1740 ng/100 ml which is still 3-fold the highest level seen either in normal women (400 ng/ml) or in hirsute women (550 ng/100 ml). Determination of 17-OHP following a short-term ACTH stimulation, therefore provides evidence of partial 21-hydroxylase deficiency.

Urine Steroid

Simultaneous serum concentrations of dehydroepiandrosterone sulfate (DHEA-S) and 17-hydroxyprogesterone (17-OHP) were compared with urinary 17-ketosteroid (17-KS) and pregnanetriol (PT) excretion during therapy in 18 prepubertal patients with the 21-hydroxylase deficiency form of congenital adrenal hyperplasia (CAH). Patients were classified into those in good, poor, or questionable control on the basis of clinical examination, skeletal age, and 17-KS and PT excretion. During therapy, use of serum steroid concentrations was found to be nearly as accurate in judging adequacy of control as use of urine steroid concentrations. Of 34 evaluations, a definite assessment of adequacy of control could be arrived at 25 times using urinary values and 22 times using both serum DHEA-S and 17-OHP concentrations. DHEA-S concentration responded sluggishly when treatment was not adequate, being greater than 100 µg/dl only in patients significantly undertreated. It was never elevated in well-controlled patients. Mid-afternoon 17-OHP concentrations were less than 200 ng/dl in well-controlled patients but readily escaped suppression and could not be used to differentiate poor from borderline control or from temporary noncompliance. Therefore, an increased DHEA-S concentration indicated poor control and a suppressed 17-OHP concentration indicated good control. The combination of normal DHEA-S level with elevated 17-OHP level, however, did not permit exact evaluation of the degree of control. Of significance is that not all patients with CAH present with an elevated DHEA-S concentration, and only in those in whom an elevated level has been documented can DHEA-S level be used as an index of control during therapy.
