Corticotropin versus hydrocortisone in the intravenous treatment of ulcerative colitis. A prospective, randomized, double-blind clinical trial

Abstract

Sixty-six patients hospitalized for ulcerative colitis were treated in a prospective, double-blind, clinical trial. They received either 120 U/day of intravenous corticotropin or 300 mg/day of intravenous hydrocortisone. Patients were randomized within strata defined by whether they had received oral corticosteroids continuously for at least 30 days before the study (group A, 35 patients), or whether they had received no such prior treatment (group B, 31 patients). Twenty-eight of the 66 patients (42%) achieved remission. In group B, the proportion of patients entering remission was greater with corticotropin than with hydrocortisone (63% vs. 27%, 0.025 less than p less than 0.05). The opposite trend was observed within group A, for whom hydrocortisone appeared more effective (53% vs. 25%, 0.05 less than p less than 0.10). Impaired adrenal responsiveness, as measured by serum cortisol and dehydroepiandosterone-sulfate levels, did not explain the different responses to therapy within the two study groups. Twenty of 28 patients whose acute therapy was successful were still in remission 1 yr after study. These data suggest that, at the doses used, intravenous corticotropin therapy of severe ulcerative colitis is the more effective choice for those patients not previously treated with corticosteroids, while intravenous hydrocortisone seems preferable for patients already receiving steroid treatment.
