Basophilic leukemia and the hypersecretion of gastric acid and pepsin.
A 48-yr-old man with chronic myelogenous leukemia and basophilia developed a duodenal ulcer and hemorrhage. Gastric analysis revealed basal hyper-secretion of acid (33.1 mEq/h) and pepsin (44.5 x 10(-4) peptic units/h). Blood, serum, and urine histamine was elevated and serum gastrin was normal. Although acid output was markedly suppressed with ranitidine (50 mg i.v.), pepsin secretion was only inhibited 63% and had returned to basal levels by the sixth hour. Maximal acid output does not suggest a trophic effect of histamine in this patient. The previously reported cases of basophilic leukemia and gastric hypersecretion or duodenal ulcer disease are reviewed.
