Abstract
Background and aim: Only a few studies have reported the long-term effects of ustekinumab on pediatric Crohn's disease. Therefore, this study aimed to describe the long-term clinical and endoscopic outcomes of ustekinumab and its safety profile in pediatric-onset Crohn's disease with anti-tumor necrosis factor failure.
Methods: Medical records of patients with pediatric-onset Crohn's disease in whom anti-tumor necrosis factor therapy failed and ustekinumab treatment was initiated from 2017 to 2022 at a Japanese tertiary children's hospital were retrospectively reviewed. The primary outcome was the continuation rates at weeks 8, 52, and 106. The secondary outcomes were the steroid-free remission rates at weeks 8, 52, and 106, changes in the Simple Endoscopic Score for Crohn's Disease, and adverse events during follow-up.
Results: Forty-three patients were enrolled. The median ages at diagnosis and ustekinumab introduction were 9.7 (interquartile range: 6.7-13.0) years and 13.6 (interquartile range: 8.0-16.0) years. The median follow-up period was 136 (interquartile range: 102-172) weeks. The continuation rates were 100%, 91%, and 80% at weeks 8, 52, and 106, respectively. The incidence of discontinuation was 6.2% per patient-year of follow-up. The steroid-free remission rates were 44%, 71%, and 80% at weeks 8, 52, and 106, respectively. The Simple Endoscopic Score for Crohn's Disease of patients in clinical remission at the last follow-up significantly decreased (P < 0.01), and the safety profile was acceptable.
Conclusions: Ustekinumab appeared effective in maintaining long-term clinical remission with endoscopic improvement in pediatric-onset Crohn's disease with anti-tumor necrosis factor failure.
