Androstenedione and its conversion to plasma testosterone in congenital adrenal hyperplasia.
The plasma concentration, production rate, and conversion ratio of androstenedione and testosterone were studied in seven children with congenital adrenal hyperplasia (CAH) of the 21-hydroxylase type. Plasma androstenedione and testosterone measured by double isotope derivative assay and estimated blood production rates were manyfold increased in the untreated state, markedly suppressed with gl...
متن کاملAndrostenedione rhythms in saliva in congenital adrenal hyperplasia.
Serial samples of saliva were collected at home by 17 patients being treated for congenital adrenal hyperplasia to determine the circadian rhythm of androstenedione as an index of therapeutic control. Single samples of blood for measurement of plasma testosterone, 170H-progesterone, and androstenedione concentrations were collected from these and a further seven patients for comparison. Plasma ...
متن کاملCongenital Adrenal Hyperplasia and Schmid Metaphyseal Chondrodysplasia in a Child
Congenital adrenal hyperplasia (CAH) is a group of hereditary diseases, which are autosomal recessive. CAH occurs due to defect in one of the cortisol coding genes and often clinically presents itself with signs of androgen overproduction. In this article, we report a case of CAH and Schmid metaphyseal dysplasia. Our literature review indicated that this report is the first attempt on CYP11B1 a...
متن کاملCircadian patterns of plasma cortisol, 17-hydroxyprogesterone, and testosterone in congenital adrenal hyperplasia.
In 11 children aged between 2 and 17 years with (nonsalt-losing) congenital adrenal hyperplasia (21-hydroxylase deficiency) blood was drawn at 90-minute intervals during a 24-hour period and levels of 17-hydroxyprogesterone, testosterone, and cortisol were measured. Levels of 17-ketosteroids and pregnanetriol were measured too in 24-hour urine samples. These measurements were taken under differ...
متن کاملCorrelation between androstenedione and 17-hydroxyprogesterone levels in the saliva and plasma of patients with congenital adrenal hyperplasia.
INTRODUCTION Congenital adrenal hyperplasia (CAH) or adrenogenital syndrome is the most common cause of female ambiguous genitalia. Management of such patients involves medical treatment using glucocorticoids such as hydrocortisone, prednisone or dexamethasone. Monitoring is done by measurement of 17-hydroxyprogesterone (17-OHP) or androstenedione in serum, plasma or saliva. The aim of this stu...
