The apparatus "Artificial Beta-Cell" or "Biostator" was used in treatment of 115 patients with diabetes mellitus and concomitant ischemia of the heart. At the same time 30 patients with diabetes mellitus and ischemia of the heart were treated for diabetes mellitus with the routine methods. Hormones such as ACTH, STH, hydrocortisone, immunoreactive insulin and S-peptide, lipid metabolism and glycosylated hemoglobin were investigated in the time course of the treatment. It was shown that adequate correction of glycemia with the "Biostator" promoted renormalization of the levels of ACTH and hydrocortisone. The results were especially favourable in the group of patients with myocardial infarction and chronic ischemia of the heart with the signs of cardiac insufficiency. Moreover, in the patients of the main group there was a tendency for normalization of lipid metabolism and glycosylated hemoglobin. The results of carbohydrate metabolism compensation in patients of the control group were not always satisfactory and the periods of compensation were longer. The clinico-biochemical indices reflected the favourable effect of the use of the "Biostator" and its advantages over the routine methods in treatment of diabetes mellitus.

A 57-year-old male, who had been suffered from hypertension and diabetes mellitus for 10 years, was admitted to the hospital because of thirst, lassitude and muscle wasting. On admission, his urinary excretion of 17-OHCS and plasma cortisol levels were elevated without diurnal variations. Plasma ACTH levels were found to be very low with repeated determinations. Dexamethasone suppression test, 2 mg 4 times a day orally for 2 days, showed no changes in plasma cortisol levels and only a mild reduction in urinary 17-OHCS excretion. Estimation of urinary catecholamines showed an increase only in norepinephrine. Abdominal computerized tomography and radionuclide scanning of adrenal glands with 131I-adosterol demonstrated a well-defined adrenal mass in the left side without apparent changes in the right side. 131I-metaiodobenzylguanidine scintigraphy was negative. At surgery, his left adrenal medulla was found to be hypertrophic in addition to the cortical tumor. The left adrenal gland was also removed. After surgery, excretion of urinary catecholamines fell to nearly the normal range and he was discharged without insulin and antihypertensive drugs. Microscopically, the cortical tumor is an adenoma consisting of lipid laden cells and eosinophilic compact cells. Medullary cells were distinctly hyperplastic in appearance and many of the cells were extensively vacuolated, suggesting an active functional status. The present report describes a patient with Cushing's syndrome who showed increased urinary catecholamine excretion due to the possible coexistence of adrenal medullary hyperplasia. As far as we know, this is the first case of Cushing's syndrome with this abnormality.

Growth hormone release inhibiting hormone (GH-RIH) was infused at a rate of 1.3 mug/min for 28 hours into four patients with acromegaly, two of whom also had clinical diabetes mellitus. Growth hormone and glucagon were suppressed throughout the infusion though delayed secretion of insulin occurred in association with both meals and an oral glucose load. Glucose tolerance was improved in one diabetic patient who was taking chlorpropamide while the other required much less insulin than usual. Secretion of endogenous thyroid-stimulating hormone was lowered in one euthyroid patient on carbimazole. Luteinizing hormone, follicle-stimulating hormone, ACTH, and prolactin were not affected. Serum somatomedin levels were reduced in one patient. There was a rapid rebound of all the suppressed hormones when the infusions stopped. Longer-acting analogues of GH-RIH will be needed before long-term therapy of acromegaly or diabetes mellitus becomes possible, but such preparations should be available soon for clinical trial.

Rare carcinoid-like ACTH-active tumour of the thymus in a woman of 40 is described. The tumour was of a solid-trabecular structure with rosette-like figures and consisted of spindle, polyhedral and roundish cells containing electron-dense granules of the neurosecretory type. Hormonal activity of the tumour was manifested in a pronounced hypercorticism with a marked adrenal hyperplasia, atrophy of sex organs and general virilization, skeletal muscle atrophy, osteoporosis, signs of diabetes mellitus, lipid hepatosis and other symptoms of a grave Itsenko-Cushing' syndrome followed by a fever. In spite of the absence of metastasis tumour was characterised by a rapid expansive growth with the compression of neck veins and venous stasis in both mediastinal organs and the tumour itself with the necrosis in its central parts. The cause of death was the thromboembolism of lung arteries from the thrombotic veins of the lower limbs.

To investigate alterations in aldosterone secretion in diabetes mellitus, the effects of angiotensin II, ACTH, and potassium on aldosterone secretion were examined in conscious unrestrained streptozotocin-induced diabetic rats (60 mg/kg, 12 weeks before study). In chronic experimental diabetic rats where PRA, plasma aldosterone concentration, and urinary excretion of prostaglandin E2 were significantly decreased, a significant attenuated response of aldosterone secretion was demonstrated after infusion of angiotensin II, ACTH, or potassium. Yet the plasma fluorogenic corticosteroids response to ACTH in diabetic rats was not significantly different from that in control rats. After acute potassium infusion (0.30 meq/kg X min), plasma potassium levels in diabetic rats were significantly higher than in control rats, although immunoreactive insulin levels remained unchanged compared to the significant elevation in control rats. These results suggest that defects in aldosterone synthesis exist in chronic experimental diabetic rats and that potassium homeostasis is impaired during acute potassium loading. This change in potassium homeostasis may be related to both insulin and aldosterone deficiencies.

Simultaneous treatment with antidiabetic drugs and beta-adrenoceptor blocking agents is frequent on account of the high incidence of diabetes and cardiovascular disease. The effects of oral doses of pindolol, metoprolol, and propranolol on the response to insulin-induced hypoglycemia and an oral glucose load were investigated. During hypoglycemia metoprolol and propranolol inhibited the clearance of insulin (2 p less than 0.01) and caused a delay of glucose nadirs. This was not observed after pindolol. Epinephrine secretion and the counterregulatory response of growth hormone, ACTH and cortisol during hypoglycemia was significantly increased following metoprolol and propranolol but not after pindolol. The hypoglycemic symptoms and signs showed a prevalence of sweating and prolonged changes in skin conductivity while palpitations were not observed during beta-blockade. Asymptomatic hypoglycemia did not occur.

A middle-aged man presented with weight loss, hypokalemic alkalosis, diabetes, hypertension, and generalized melanosis. Marked elevation of urinary free cortisol (655 micrograms/24 h) and plasma ACTH (2445 PG/ML) SUGGESTED THE DIAGNOSIS OF ECTOPIC ACTH syndrome. The plasma concentrations of cortisol and urinary 17-hydroxycorticosteroids increased paradoxically during the administration of dexamethasone without a corresponding change in the plasma ACTH level. Metyrapone administered over 24 h also markedly incrased both urinary free cortisol and 17-hydroxycorticosteroids. Selective venous sampling of plasma ACTH did not reveal a gradient between jugular vein and peripheral venous blood. The laboratory findings supported the diagnosis of ectopic ACTH syndrome. However, belated occurrence of visual changes necessitated surgical exploration, resulting in the diagnosis of pituitary carcinoma. A fluorescent antibody to ACTH reacted strongly with the atypical pituitary cells. This rare case documents that severe melanosis in Cushing's disease can occur without prior adrenalectomy and is consistent with the diagnosis of pituitary carcinoma. Furthermore, melanosis observed in patients with pituitary carcinoma is associated with ACTH levels similar to those occurrring in the ectopic ACTH or Nelson's syndrome.

Deficiencies of corticotrophin (ACTH), growth hormone, and prolactin were documented in a woman with diabetes mellitus and Sheehan's syndrome. The patient's ACTH deficit appeared to be secondary to a hypothalamic abnormality since on two occasions the patient had a marked plasma ACTH response to vasopressin but not to insulin induced hypoglycaemia. It is postulated that the deficits of these three adenohypophysial hormones were instrumental in causing a severely impaired aldosterone secretory capacity in response to sodium restriction and an angiotensin infusion. In addition, the patient had an unusual form of thyroid dysfunction that was in part reversed with hydrocortisone replacement. The patient's unfortunate death during a hypoglycaemic crisis allowed correlation between her extensive antemortum endocrine testing and her pathologic anatomy.

In idiopathic haemochromatosis, excessive iron deposits include adrenal cortex, and mainly the zona glomerulosa. In this view, we measured basal and post-stimulative values of plasma cortisol, aldosterone and renin activity (RA) in two groups of patients: 1) 9 normal-salt repleted subjects (NSR) who were subjected to iv ACTH and furosemide tests, 2) 10 patients who were subjected to chronic salt depletion (CSD), to iv ACTH and furosemide tests. The results were compared with two groups of 7 healthy volunteers (NSR and CSD). In the patients, basal cortisol values were either normal or increased in cases of poorly controlled diabetes (21 +/- 2.1 microgram/100 ml, P < 0.01) and cortisol increase after ACTH injection was normal (to 43.3 +/- 4.3 microgram/100 ml). In the 9 NSR patients, basal aldosterone (7.75 +/- 1.5 ng/100 ml) and RA (1.55 +/- 0.27 ng/ml/h) values were normal; aldosterone and RA rose after furosemide injection: these increases were similar in these patients (respectively to: 13.5 +/- 2.2 ng/100 ml and 4.3 +/- 0.6 ng/ml/h) and in the 7 NSR controls. In the 10 CSD patients, basal aldosterone and RA values were always increased (26.5 +/- 3.2 ng/100 ml and 8.5 +/- 2.3 ng/ml/h) as much as in the 7 CSD controls. After ACTH administration, aldosterone values (26.1 +/- 4 in NSR patients, 54 +/- 8 ng/100 ml in CSD patients) were the same as in the two control groups. This study suggests that there is no adrenocortical deficiency in idiopathic haemochromatosis, in spite of excessive iron deposits in the adrenal cortex.

Two patients presenting with diabetes mellitus and hypokalaemia resulting from markedly increased ACTH and cortisol secretion are described. Neither patient showed any evidence of a tumour and both responded dramatically to treatment with metyrapone in that all abnormal clinical features disappeared, ACTH concentrations returned to normal and both patients showed prolonged remission after metyrapone treatment was stopped. One patient relapsed after a severe viral illness and the administration of dexamethasone and cortisone. It is suggested that these cases may represent an unusual form of Cushing's syndrome in which ACTH secretion is stimulated by increasing concentrations of cortisol. When these are reduced by metyrapone administration ACTH secretion falls in parallel and prolonged remission of disease may result.
