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.

ISSN 0804–4643 To determine the value of 3α-androstanediol glucuronide (3-AG) measurements in children with congenital adrenal hyperplasia, we compared serum 3AG, 17-hydroxyprogesterone (17-OHP), androstenedione (A), testosterone (T) and dihydrotestosterone (DHT) levels and 24-h urinary 17-ketosteroid (17-KS) excretion in 42 female children with congenital adrenal hyperplasia due to 21-hydroxylase deficiency, including 27 with the simple virilizing and 15 with the salt-losing form. Their mean age was 74.5 ±48.5 months (range, 6–194 months). Twenty-four-hour urinary 17-KS excretion and serum 3-AG, A, T, DHT and 17-OHP levels were measured in the patients. The values were less than the mean + 2 sd of the control group in 63%, 74%, 67%, 69%, 60% and 31% of the patients, respectively. Serum 3-AG levels correlated with 24-h urinary 17-KS excretion (r = 0.66) and plasma A (r = 0.80), 17-OHP (r = 0.56), T (r = 0.79) and DHT (r = 0.62) levels. We conclude that serum 3-AG is a useful metabolic index in the management of children with congenital adrenal hyperplasia. Şükrü Hatun, Türk-İş Blk, 274/7, Aydinlikevler, Ankara, Turkey

21 Hydroxylase Deficiency

ABSTRACT Plasma aldosterone and 17α-hydroxyprogesterone (17-OHP) concentrations were measured in 35 patients with congenital adrenal hyperplasia resulting from 21-hydroxylase deficiency. Ten patients had never been treated and among them were 4 salt-losing infants. Both aldosterone and 17-OHP were high in the 6 untreated non salt-losers. The values ranged respectively from 110 to 376 pg/ml and from 150 to 292 ng/ml. Results were variable in the 4 salt-losers. Three out of 5 untreated non salt-losers who were submitted to a low sodium diet, responded by doubling their aldosterone levels. When plasma 17-OHP concentrations were < 30 ng/ml, the mean aldosterone level in the treated non salt-losers (n = 6) was 15.3 pg/ml ± 4.3 (se). This value was not different from the mean level found in the control children (n = 7), 18.8 pg/ml ± 3.2. In the treated salt-losers (n = 9), the measured aldosterone levels were ≦ 10 pg/ml 7 times out of 9. When the treated patients exhibited plasma 17-OHP concentrations > 30 ng/ml, the salt-losers (n = 11) were distinguished from the non salt-losers (n = 8) in that they showed a significantly lower aldosterone mean level, 24.6 pg/ml ± 4.3 against 69 pg/ml ± 13.4 found in the non salt-losers. The salt-losers displayed no aldosterone increases to synthetic ACTH stimulation under treatment or at the withdrawal of treatment, while positive aldosterone responses were often observed in the non salt-losers. In the latter group, studied under different conditions (with and without therapy, on low sodium diet, after ACTH test) a significant correlation was found between aldosterone and 17-OHP levels expressed in log. values, (n = 38, r = 0.80, P < 0.001). The relationship could also be established with the values obtained from all the salt-losers, but it was less significant, (n = 35, r = 0.46, P < 0.02).

Abstract. A radioimmunoassay for 21-deoxycortisol is described. The immunogen, 21-deoxycortisol-3-(O-carboxymethyl) oxime-bovine serum albumin, was prepared, the antisera raised against it were studied and the reliability of the assay was checked. The antiserum selected cross-reacted with 11-deoxycortisol (0.08%), corticosterone (0.25%), cortisol (0.6%) and 17-hydroxyprogesterone (1.6%). 21-deoxycortisol was separated by celite partition chromatography and eluted in the 70/30 (v/v) isooctane/ethyl acetate fraction together with 11-deoxycortisol and corticosterone. The radioimmunoassay was used to measure 21-deoxycortisol in the plasma of normal subjects and patients with androgen excess. In normal subjects, men (0.19 ng/ml ± 0.08) and women (0.18 ng/ml ± 0.09) had similar basal levels (mean ± sd). One hour after ACTH stimulation, these levels were increased by a factor of 3.5. In 7 patients treated for classical congenital adrenal hyperplasia associated with 21-hydroxylase deficiency, basal values varied between 9.1 and 39.9 ng/ml (measured at 8 a.m.). In 7 untreated women with lateonset congenital adrenal hyperplasia (with 21-hydroxylase deficiency), ACTH-stimulated levels were increased to between 9 and 25.5 ng/ml. In 14 heterozygous carriers of 21-hydroxylase deficiency, diagnosed by HLA genotyping, all ACTH-stimulated levels were well above the highest corresponding levels in normal subjects, whereas 17-hydroxyprogesterone levels remained within the normal range in 9 of the cases.

Abstract Background: In congenital adrenal hyperplasia (CAH), adjusting hydrocortisone dose during childhood avoids reduced adult height. However, there are currently no CAH-specific charts to monitor growth during treatment. Our objective was to elaborate growth reference charts and bone maturation data for CAH patients. Methods: We conducted a retrospective observational cohort study, in 34 French CAH centers. Patients were 496 children born 1970–1991 with genetically proven 21-hydroxylase deficiency. Their growth and bone maturation data were collected until age 18 together with adult height, puberty onset, parental height, and treatment. The mean (SD) heights were modeled from birth to adulthood. The median±1 SD and ±2 SDs model-generated curves were compared with the French references. A linear model for bone maturation and a logistic regression model for the probability of short adult height were built. Results: Growth charts were built by sex for salt wasting (SW) and simple virilizing (SV) children treated before 1 year of age. In girls and boys, growth was close to that of the general French population up to puberty onset. There was almost no pubertal spurt and the mean adult height was shorter than that of the general population in girls (−1.2 SD, 156.7 cm) and boys (−1.0 SD, 168.8 cm). Advanced bone age at 8 years had a strong impact on the risk of short adult height (OR: 4.5 per year advance). Conclusions: The 8-year bone age is a strong predictor of adult height. It will help monitoring the growth of CAH-affected children.

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.

21 Hydroxylase Deficiency

The urinary excretion of two Δ5-3β-OH, 16α-hydnoxysteroids, 16-OH-pregnenolone (16-OH-PG), and 16-OH-dehydroepiandrosterone (16-OH-DHA), has been determined in 18 patients with the C-21 hydroxylase deficiency type of congenital adrenal hyperplasia (CAH). The excretion of 16-OH-PG was generally above the normal range in young infants, fell over the first 4 months and was present in only one of eight control urine samples from patients with CAH over 5 months of age. The excretion of 16-OH-DHA was generally within the normal range in the young infants, fell over the first 4 months, and was not found in urine samples from CAH patients over 5 months of age. ACTH was administered to eight of the CAH patients and caused an increased excretion of both steroids when they were present in control urine samples. Of the five patients receiving ACTH who had neither steroid present in control urine, 16-OH-PG appeared in the two youngest but 16-OH-DHA appeared in none. The ratio of urinary 16-OH-PG/16-OH-DHA was significantly greater in the CAH patients than in the endocninologically normal patients. It was concluded that the pattern of excretion of 16-OH-PG and i6-OH-DHA in patients with CAH is an exaggeration of the normal infant pattern caused by the endogenous ACTH stimulation. The possible role of the fetal zone of the adrenal cortex in the secretion of these steroids was considered but the available evidence indicated that the permanent cartical zone was the site of origin.

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.
