Infliximab Rescue Therapy in Pediatric Severe Colitis.
INTRODUCTION: Clinical remission has been achieved with infliximab in patients with refractory ulcerative colitis (UC). However, there is conflicting data regarding its effectiveness as rescue therapy in adult acute severe colitis. Furthermore, pediatric inflammatory bowel disease (IBD) is associated with more severe disease that may be less amenable to attempted rescue. We reviewed our experience and outcomes with pediatric severe colitis after attempted inpatient rescue with infliximab.
METHODS: A single-institution, retrospective review was conducted of pediatric patients with UC or indeterminate colitis who received inpatient rescue infliximab therapy from 1/2000 to 1/2019. Rescue infliximab therapy was considered if a child failed non-biologic therapy or progressed to fulminant or toxic colitis. Primary outcome was failed therapy resulting in colectomy. A p-value of < 0.05 determined significance.
RESULTS: Thirty patients met inclusion criteria. The median age at administration of rescue infliximab treatment was 14 years [IQR 13,17]. Rescue therapy with infliximab was successful in 33% (n = 10), while 67% (n = 20) underwent colectomy. Children on maintenance steroids were less likely to be successfully rescued with infliximab and require colectomy (p = 0.03). Children requiring colectomy had a longer hospital stay (p = 0.03), more abdominal radiographs (p = 0.01), and were on a longer duration of antibiotics (p = < 0.01) compared to children who were successfully rescued with infliximab. There was no difference in baseline vital signs or laboratory abnormalities between the two groups.
CONCLUSION: In severe acute ulcerative or indeterminate colitis cases where infliximab has not been previously used, rescue infliximab can be used to avoid colectomy but has a high failure rate.
