| Zusammenfassung: | OBJECTIVE: To assess the utility of serum steroids measurement in monitoring the treatment of children with congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (21OHD) METHOD: Nineteen Patients with CAH 21OHD aged (3.67±1.54) years treated with hydrocortisone and fluorocortisone replacement were followed up at an intervals of 0.33 - 1.0 years over a period of (1.47±0.7) years. At each visit, roentgenograms of the hands and wrists were taken, fasting peripheral blood were collected to test serum dehydroepiandrosterone sulfate, progesterone, 17-hydroxyprogesterone (17-OHP), androstenedione (Δ4-A), testosterone, free testosterone, estrone, and estradiol concentrations at 8 AM in the morning before the first dose of glucocorticoid. Then the patients were classified as being in "Good Control" or in "Poor Control" based on clinical criteria including signs of androgen excess, growth velocity and bone age increment at each interval. Comparisons were carried out between the serum steroid concentrations of the two groups. The receiver operating characteristic (ROC) curves were used to determine the cut-off values for diagnosing "Poor Control" RESULT: Both of serum Δ4-A and 17-OHP concentrations were higher in "Poor Control" group than those in "Good Control" group [5.95 (2.23-11.2) nmol/L versus 1.05 (1.05-9.89) nmol/L, t=2.19; 13.85 (6.06-20) µg/L versus 3.67 (0.42-21.1) µg/L, t=2.17; P<0.05, respectively]. The ROC curves for serum Δ4-A concentrations, serum 17-OHP concentrations, serum Δ4-A in combination with 17-OHP concentrations were constructed with areas under the ROC curves (95%CI) of 0.76 (0.62, 0.90), 0.75 (0.62, 0.88), 0.69 (0.54, 0.84), P<0.05, respectively. Serum Δ4-A of 3.9 nmol/L had 0.78 of sensitivity and 0.75 of specificity in diagnosing "Poor Control". Serum 17-OHP of 7.1 µg/L has 0.67 of sensitivity and 0.71 of specificity in diagnosing "Poor Control" CONCLUSION: Each of serum 17-OHP or/and Δ4-A concentration was of significance in diagnosing "Poor Control" during the glucocorticoid replacement treatment of CAH 21OHD, with the diagnostic efficacy being serum Δ4-A concentration, serum 17-OHP concentration and serum Δ4-A in combination with 17-OHP concentration in descending order. Serum Δ4-A and 17-OHP concentrations may be used as the biochemical indicators to monitor the therapy of CAH 21OHD |
