We aimed to investigate the dynamics of adrenocorticotropin (ACTH) and cortisol secretion in pituitary-dependent Cushing's syndrome with bilateral macronodular adrenal hyperplasia presenting as a single adrenal macronodule, and to determine the imaging characteristics of this syndrome. Three female patients were studied. Plasma ACTH and serum cortisol secretion were studied by determining their rhythmicity and pulsatility and their responses to the administration of ovine corticotropin-releasing factor, thyrotropin-releasing hormone, metyrapone, tetracosactrin, insulin and dexamethasone. Techniques used to localize the anatomical lesion were bilateral simultaneous inferior petrosal sinus sampling, magnetic resonance examination of the pituitary, computed tomography (CT) scanning and [75Se]cholesterol scintigraphy of the adrenal glands. Plasma ACTH and serum cortisol levels were measured using a commercial radioimmunoassay and an immunoradiometric assay. The ACTH and cortisol pulse number and amplitude were calculated using established computer software. In all three patients ACTH and cortisol secretory dynamics fulfilled the requirements for diagnosis of pituitary-dependent Cushing's syndrome. A close relationship between ACTH and cortisol pulses also favored a pituitary dependency. Study of the amplitude of cortisol pulses classified two patients in the group of hypopulsatile Cushing's disease. Adrenal CT scanning demonstrated the presence of a large single nodule. [75Se]Cholesterol scintigraphy showed bilateral radionuclide uptake, although mostly localized over the adrenal nodule. All patients underwent successful trans-sphenoidal hypophysectomy. Over a period of 1 year, a slow shrinkage of the adrenal nodule was observed in two patients, while no change in volume was observed in one patient.(ABSTRACT TRUNCATED AT 250 WORDS) [less ▲]

The effects of octreotide pretreatment before surgery were assessed in 48 acromegalic patients who underwent trans-sphenoidal surgery to remove pituitary adenoma, and compared with 107 patients who did not receive octreotide before surgery. Pretreated patients received octreotide 100 micrograms, thrice daily for 3 to 6 weeks (group 1), or 100 to 500 micrograms, thrice daily for 3 to 39 months (group 2). Total remission of symptoms was seen in 54%. Partial remission of symptoms occurred in 39%. Octreotide pretreatment reduced plasma GH levels by > or = 50% in all patients. GH levels were reduced to < 2 micrograms/1 in 3/14 group 1 cases and 13/34 group 2 cases. Tumour shrinkage occurred in 56.5% of patients. Marked tumour shrinkage (> 25%) occurred in more group 2 patients (10/32 vs 1/14). The tumour was soft in 39 patients, firm in 6 and hard in 3 cases. Soft consistency aided surgical removal of adenomas. Remission was greater in enclosed adenomas than in invasive tumours in both octreotide pretreated and nonpretreated acromegalics (76 vs 30%). Remission was more likely if the adenoma was less than 16 mm. Remission rate was significantly greater (p < 0.05) in all octreotide pretreated than in untreated patients for enclosed adenoma, but not for invasive adenoma. Octretide pretreatment can be recommended for three to four months prior to surgery. [less ▲]

Nous avons utilisé la cabergoline, un nouvel agoniste dopaminergique, dans le traitement des adénomes hypophysaires à prolactine. Cinquante-six patients atteints de micro-adénome dans 35 cas et de macroadénome dans 21 cas ont été traités durant des périodes variant entre 1 et 17 mois à des doses de cabergoline variant entre 0,25 mg et 2 mg par semaine, prises à raison de 1 à 4 fois par semaine. Cette nouvelle substance nous est apparue extrêmement efficace et très bien tolérée [less ▲]
