Background

Intravenous steroid therapy is the main initial treatment for acute severe ulcerative colitis (ASUC). However, steroid dependence in patients who were treated with intravenous steroid therapy for ASUC is not fully evaluated. We aimed to determine the prevalence and risk factors of corticosteroid dependence after treatment of ASUC. 

Methods

Adult patients who were admitted for the treatment of ASUC satisfying Truelove-Witts criteria from January 2015 to December 2020 were included in the study. Steroid dependence was defined as a failure to taper steroids below 10 mg within 3 months from initiating intravenous therapy or relapse within 3 months after steroid discontinuation.

Results

Among a total of 140 patients who received intravenous steroids as initial treatment for ASUC, 105 (75.0%) showed a response while 35 (25.0%) were refractory to steroids. Of 105 patients who responded to intravenous steroid therapy, 21 (20.0%) showed steroid dependence during the follow-period. Demographic and clinical variables were not significantly different between steroid-dependent and steroid response groups. However, initial C-reactive protein (CRP) levels in steroid-dependent groups were numerically lower compared with those in the steroid response group with statistical significance (4.4 ± 4.6 mg/dL versus 7.0 ± 6.4 mg/dL, p = 0.04).

Conclusion

A total of 20.0% of responders to intravenous steroid treatment for ASUC had a steroid dependency during follow-up. The demographic and clinical features of ASUC according to the presence or absence of steroid dependency were similar. Initial CRP levels were low in patients with steroid dependence.
