Screening for late onset congenital adrenal hyperplasia due to 21-hydroxylase deficiency.

Basal and post-ACTH levels of 17 alpha hydroxy-progesterone (17 OHP) were determined in 53 subjects with hirsutism. Late onset congenital adrenal hyperplasia (LOCAH) was detected in five (10.6%) on the basis of elevated basal and/or ACTH stimulated levels of 17 OHP. Of the five patients, two were considered to have a heterogygous state on account of a small rise in stimulated 17 alpha OHP. Screening tests for LOCAH are essential as the clinical diagnosis is not otherwise possible for this treatable and often familial disorder.

Ketoconazole in the treatment of Cushing's disease.

Six patients with Cushing's disease received ketoconazole for 7-10 weeks following ketoconazole challenge test. Clinical and hormonal alterations in circulating cortisol, 17 OH progesterone, androstenedione and testosterone were assessed during the therapy. There was significant clinical improvement which corresponded to a fall in cortisol, androstenedione and testosterone. The rise in 17 OH progesterone and the fall in cortisol suggest a blockade at 17,20 desmolase and 11 B-hydroxylase in the cortisol bio-synthetic pathway.

Circulating cortisol & related steroids following ketoconazole challenge in Cushing's disease.

Circulating levels of cortisol, 17 alpha hydroxy progesterone and delta 4 androstenedione were analysed by specific radioimmunoassays in 11 patients with Cushing's disease before and at 2, 4, 6, 12 and 24# h following an oral dose of 400 mg ketoconazole. A significant fall in cortisol (26 - 79.6%, 59.8 +/- 18.7 SEM), delta 4 androstenedione (21.5 - 63.3%, 47.8 +/- 4.87) with a concomitant rise in 17 alpha hydroxy progesterone (113 - 218%, 116 +/- 11.43) were noted, suggesting inhibition of 17, 20 desmolase and 11 beta-hydroxylase enzymes in cortisol biosynthetic pathway.

Circulating androgens in hirsutism.

The androgen status in fifty consecutive women with hirsutism in the reproductive age group referred to the endocrine clinic was studied. Mean BMI was 24.3 +/- 5.6 kg/M2, 42% had menstrual disturbances and 30%, had severe hirsutism. The hirsute patients had significantly higher estimates of testosterone (48%), dihydrotestosterone (38%) and androstenedione (86%). Based on clinical and hormonal data, polycystic ovarian disease was diagnosed in 20 patients, nonclassical 21 hydroxylase deficiency in one and idiopathic hirsutism in 29.

Effects of vitamin D supplementation in pregnancy.

Serum calcium, inorganic phosphate and heat-labile alkaline phosphatase (HLAP) have been estimated in maternal and cord sera of 120 pregnant women at labour. 75 women who did not take any vitamin D supplements during pregnancy showed statistically significant hypocalcaemia, hypophosphataemia and elevation of HLAP. Hypocalcaemia and hypophosphataemia were present in cord blood, too. 25 women who had received 1,200 U vitamin D/day throughout the 3rd trimester, showed significantly lower HLAP levels and increased fetal birth weight but there was no other improvement in maternal or cord blood chemistry. Administration of vitamin D in two large doses of 600,000 U each in the 7th and 8th months of pregnancy in 20 women proved more efficacious. Statistically significant improvement was observed in all the three biochemical parameters in maternal as well as cord sera. Fetal birth weight was also significantly greater with this mode of therapy.
