Background: The role of intravenous (IV) cyclosporine in severe Crohn’s colitis (CC) is poorly studied.
Aim: Our primary aim was to determine the in-hospital colonic resection rate in patients with severe CC who received IV cyclosporine, and the potential predictors of resection among these patients.
Methods: An inpatient pharmacy query of all patients who received IV cyclosporine at Mount Sinai Medical Center for 12.5 years after January 1, 1996 was reviewed. Patients with CC or indeterminate colitis favoring Crohn’s were included and their medical records were reviewed. Subsequent need for colonic surgery was assessed. A Kaplan-Meier plot with log-rank testing was performed to determine the rate of colonic surgery avoidance. Forward stepwise logistic regression was performed to determine independent predictors of surgery.
Results: Forty-eight patients met our inclusion criteria. Prior thiopurine and anti-tumor necrosis factor (anti-TNF) use was 85% and 69%, respectively. The median follow-up time was 12 months (range, 1 to 60 mo). 12.5% of patients required colonic resection during their admission for IV cyclosporine. Anti-TNF use in the 4 weeks preceding IV cyclosporine was the only predictor of surgery in this setting (P=0.05). The cumulative colonic surgery avoidance rate was 72±13% at 6 months and 59±15% at 12 months.
Conclusions: The use of IV cyclosporine resulted in a low rate of in-hospitalization colonic surgery among CC patients with severe disease, the majority of whom previously failed anti-TNFs and thiopurines.
