Combination Treatment with Antibiotics and Glucocorticosteroids for Severe Ischemic Colitis

Ischemic colitis (IC) is most common in the elderly and patients with multiple comorbidities. It carries significant mortality. As yet no evidence-based therapeutic management exists. Aim of the study was to test therapeutic efficacy of a combination of prednisolone and antibiotics.

Prospective cohort study with retrospective analysis performed in a single teaching hospital in Germany. Consecutive patients with strict diagnostic criteria of severe IC, including colonoscopy, histology, and laboratory tests, were recruited. Main outcome measures were in-hospital mortality and number of operations counted within the hospital stay. Severity scores were calculated and biomarkers determined during the course of the hospital stay.

A total of 342 patients with an International Classification of Diseases of IC were identified. About 151 patients met the diagnostic criteria and a total of 44 patients fulfilled all inclusion and exclusion criteria of severe IC and constituted the group of patients eligible for analysis. Five out of 44 patients (11.4%) died (in-hospital mortality). Surgery was performed in 3 patients (6.8%), 2 patients survived. The hospital stay lasted 14.0 ± 8.5 day and was significantly correlated with comorbidity (rs = 0.314, p = 0.038). No serious adverse events were observed.

This is the first prospective study on therapeutic efficacy and safety in severe IC. The combination of intravenous antibiotics and intravenous prednisolone turned out to be safe and revealed promising efficacy.
