Cushing's Ulcer as a Consequence of Adrenocorticotropic Hormone Administration for Infantile Spasms

Abstract

Adrenocorticotropic hormone (ACTH) is the treatment of choice for infantile spasms despite its multiple side effects. This case represents a previously unreported side effect, peptic ulceration, occurring during ACTH treatment of infantile spasms. Two pathophysiologic mechanisms are proposed and examined. A direct effect of ACTH on the duodenum is considered but deemed unlikely. Alternatively, the combination of the patient's communicating hydrocephalus and ACTH's central effects is proposed to have led to increased intracranial pressure and a Cushing's ulcer. The need for pretreatment neuroimaging and H2-receptor antagonist use during ACTH therapy in all cases, along with gastrin level measurements in selected cases, is recommended.
