[Action of bromocriptine on glucose metabolism in diabetics].

24 diabetics, (9 thin diabetics, 14 cases of maturity onset diabetes, 6 intermediate forms and one case of partial pancreatectomy) received 7.5 to 20 mg of bromocriptine (CB 154) per 24 hours. A definite improvement in glucose metabolism was noted in 6 cases, a definite aggravation in 4 cases; 14 results were not significant (p-0.05). The efficacy of CB 154 did not depend on the clinical type nor on the patient's age. It appeared related to duration of the diabetes (2 years and 3 months in improved patients, 11 years in aggravated patients) and perhaps the degree of retinopathy (more frequent and severe in aggravated patients). The improvement seems to be linked to the existence in certain diabetics of a paradoxical regulation of STH secretion as in acromegaly. The possibility of a peripheral effect of bromocriptine on insulin and glucagon is discussed. The CB 154 test (estimations of STH after a single dose of 2.5 mg) permits one to foresee the efficacy of the drug and perhaps the risk of diabetic retinopathy.

[Follow-up study of non-neoplastic Cushing's syndrome followed by paraneoplastic Cushing's syndrome after removal of a malignant pulmonary tumor. Role of the diffuse endocrine system and APUD (amine precursor uptake decarboxylase) cells].

A 27 year old woman had in 1965, a paraneoplastic Cushing's syndrome was cured by removal of a pulmonary tumour. The case was published in June 1968. After a normal pregnancy, a recurrence of the Cushing's syndrome in 1969 led in 1970 to bilateral total adrenalectomy in two stages. Pathology showed hyperplastic adrenal glands. After 11 years follow up, we have not noted any relapse of the tumour nor of the Cushing's syndrome. The pathological appearance of the lung carcinoma removed in 1965 (endocrinoid or neuroid structures) suggests that this was an "apudoma" and that the recurrence of the Cushing's syndrome was perhaps an "apudomatosis" involving the pituitary ACTH cells.
