A controlled evaluation of intravenous adrenocorticotropic hormone and hydrocortisone in the treatment of acute colitis.

This study compares the efficacy of intravenous adrenocorticotropic hormone (ACTH) with intravenous hydrocortisone in the treatment of patients with symptomatic inflammatory bowel disease. Drug doses were pharmacologically equivalent on the basis of achieved plasma cortisol levels and continuously monitored urinary corticoid excretion rates. Drug selection and patient evaluation were accomplished with a random double blind technique. Evaluation of 22 consecutive hospital patients indicates that ACTH and hydrocortisone, when administered intravenously in pharmacologically equivalent dosage, are therapeutically equivalent, that response to ACTH is rapid, with no therapeutic lag, and that differences in therapeutic responses cannont be corrrelated with differences in systemic steroid levels.

[Hypophyseal gonadotropin secretion in sexual precocity with McCune-Albright's syndrome].

In three young girls with isosexual precocity and fibrous dysplasia of bones, plasma gonadotropins (LH and FSH) response to releasing hormone (LH-RH) has been much under the mean response in true female precocious puberty. These data and those previously reported in the literature suggest that MacCune-Albright's syndrome correlates to an hypothalamo-pituitary dysfunction rather than to a true prematurity.

Cortisol secretion in Nelson syndrome: Persistence after "total" adrenalectomy for Cushing syndrome.

In two patients who were severely pigmented (Nelson syndrome) following bilateral adrenalectomy for Cushing syndrome, symptoms of hyper-cortisolism developed while they were receiving only physiologic steroid replacement. Cortical assays proved that endogenous cortisol production had not been obliterated. Even after total adrenalectomy, steroid measurement should be performed to guard against adrenocortical excess.

[Functional state of the adrenal cortex in patients with cancer of the rectum].

The level of 17-ketosteroids and 17-ketogenic steroids in the diurnal urine was determined in 70 patients with rectal cancer prior to and after ACTH administration. In most patients the initial excretion of the steroids under study was found to be decreased. 17-ketosteroids excretion is reduced more frequently in patients over 50 years of age and in females. In a predominant number of patients functional reserves of the adrenal cortex are decreased.

[Effects of a vagolytic substance on the circadian rhythm of the ACTH-secreting system in man].

The circadian rhythm of plasma cortisol and urinary 17-hydroxy-corticosteroids has been studied in 6 normal volunteers both in basal conditions and after the administration of a single dose of 30 mg of a banthine derivative (the beta methyl-beta-isopropylaminoethyl ester bromide of xantene-9-carbonic acid, "Pervagal") given orally once a day at different hours (midnight, 4 AM, 8 AM, noon, 4 PM, 8 PM). The vagolytic drug inhibits the cortisol secretion only when administered at 4 PM, 8 PM or midnight, whereas it is ineffective when given at different hours. If don't exist circadian variations of the bio-availability of the drug employed, our results suggest that also in human beings as well as in experimental animals, the cholinergic mechanisms are effective, over all if not exclusively, in starting the circadian activation of the hypothalamo-pituitary-adrenal system.

[Hormone and mediator content in the blood of the adrenals and in the peripheral blood in hypertension].

The concentration of the fractions of corticosteroids, aldosterone, catecholamines, and cyclic nucleotides (cAMP and cGMP) in blood of the adrenal veins and the activity of renin in blood of the renal veins were studied in 22 patients with stages IIA and IIB hypertensive disease. At the same time the content of these substances in the peripheral blood was determined and compared with the level of steroid and catecholamine excretion in the daily urine. An increase in the content of free 11 OCS and F fractions in the peripheral blood and blood of the adrenal veins was revealed in all patients examined.

[Serum neuraminic acid level in patients with cerebrovascular disorders].

The authors determined the level of neuraminic acid in the serum of 50 patients with encephalomalacia and 25 patients with cerebral haemorrhages on the 1st, 3d and 7th days of the disease. Twenty healthy subjects served as controls. A statistically significant rise in the concentration of this substance was observed in both groups of patients throughout the whole period of observations.

[Certain pathogenetic mechanisms of development of atherosclerosis in dogs, induced without the use of cholesterol].

Chronic investigations (up to 3 years) conducted in dogs have evidenced that periodic disturbances of vascular permeability produced by using dicoumarin with a long-term blocking of the thyroid function greatly aggravate pathological manifestations induced by the action of 6-methylthiouracil. They result in the development in the animals of endogenous hypercholesterinemia, elevated content in the blood of beta-lipoproteins and in a periodic rise of the arterial pressure. These changes were particularly spectacular at the final stage of the experiment in animals with marked manifestations of atherosclerosis and were accompanied by reduced stand-by potentialities of the adrenal gland, disruption of metabolic processes in the myocardium along with the slowed down resorption of NaI131 from the heart muscle. The sensitivity of the heart to adrenalin was down too.

Treatment of acne with cyproterone acetate and ethinyl estradiol.

Tablets containing 2 mg cyproterone acetate and 0.05 mg ethinyl estradiol in a calendar package of 21 days were used as an oral contraceptive to treat acne. The series comprised 20 patients. The women were 18--43 years of age, and all had acne which had previously been resistant to therapy. The treatment was continued for 6 months. Serum testosterone, 17-OHCS, 17-KS, serum ALAT and gamma-GT were recorded prior to the treatment at 3 and 6 months. Ten patients responded well to the treatment, 5 responded moderately well, 3 experienced no change, and 2 became worse. The serum testosterone level fell during the therapy and the ALAT level rose, though only one pathological ALAT value was recorded.
