Abstract
To elucidate further the pathogenesis of steroid-induced ulceration, plasma gastrin levels, both basal and after a test meal, were studied in normal volunteers and patients treated with glucocorticoids or corticotropin. In normal subjects the acute intravenous administration of 100 mg prednisolone had no effect on plasma gastrin levels. After oral administration of predinisolone (40 mg daily, for four days) a significant increase of the basal, the reactive, and the over 90-min integrated gastrin release was observed. In this group, the glucocorticoid treatment had a slight, but significant influence on gastric acid and pepsin secretion, while acidity and pepsin output stimulated by pentagastrin was not affected. In patients treated with prednisolone for more than 24 weeks, the oral administration of this hormone failed to alter basal gastrin values but affected significantly secretion after the test meal. In patients with multiple sclerosis, after intramuscular administration of corticotropin (60 IU daily, for 12 days), an increase of the basal, the reactive, and the integrated gastrin release also was found. Glucocorticoid-induced hypergastrinemia provides information on the pathogenesis of steroid-induced ulceration.
