The 24-h plasma cortisol profile was obtained at 20-min intervals in 18 patients with Cushing's syndrome (10 with Cushing's disease, 5 with adrenal adenoma, 2 with ectopic ACTH secretion and 1 of questionable aetiology). The mean cortisol level was maximum in the case of ectopic ACTH secretion. The coefficient of variation of cortisol levels was subnormal(More)
In a type II diabetic patient presenting with chronic hypokaliemia secondary to a selective renal tubulopathy, insulin sensitivity was explored three times during a euglycemic hyperinsulinemic clamp procedure at two rates of insulin infusion: 1 and 10 mU/kg/min: once before treatment of hypokaliemia and once after successful correction of hypokaliemia with(More)
A 58-yr-old man presented a Cushing's syndrome gradually developed for two years, and a cervical tumor. Urinary free cortisol and 17-hydroxy-corticosteroids were elevated and non suppressible under high dose dexamethasone (8 mg a day X 2 days). Plasma calcitonin (7,200 pg/ml), CEA (803 ng/l), beta LPH (624 pg/ml), and CRF (29 pg/ml) were elevated. Total(More)
Urinary (CPU) and plasma C peptide values at baseline (CP0) and under stimulation with glucagon were determined in healthy subjects (n = 17) and in insulin-dependent (IDD, n = 45) and non insulin-dependent (NIDD, n = 32) diabetics. A significant difference in the parameters of insulin secretion (x? SD) was found on the one hand between the IDD group (CPU =(More)
The prevalence of microalbuminuria and persistent proteinuria was studied in a population of 801 diabetic patients (535 with type II and 266 with type I diabetes). Urinary albumin excretion rate (AER) was measured on morning samples by laser nephelometry. Normoalbuminuria, as defined, in the absence of contaminated urine, by an albumin: creatinine (A/C)(More)
We have determined peripheral venous somatostatin like immunoreactivity (SLI) levels in 11 normal subjects (blood glucose--BG--: 4.4 +/- 0.1 mM; ketone bodies--KB--: 90 +/- 12 microM; plasma free fatty acids--FFA --: 340 +/- 42 microM), 4 Biostator controlled insulin dependent diabetics (BG: 5.4 +/- 0.2 mM; FFA: 418 +/- 38 microM; KB: 226 +/- 41 microM) and(More)
