Hypersensitivity Reaction to Ustekinumab in Pediatric and Young Adult Inflammatory Bowel Disease Patients: A Case Series.

Ustekinumab (UST) is a human IgG1K monoclonal antibody that binds to the p40 receptor subunit bound by cytokines IL-12 and IL-23. It is indicated in both Crohn's disease and ulcerative colitis as a second-line agent. The safety and efficacy of UST in children and young adults has not been thoroughly studied.

Rapid Infliximab Infusion in Children with Inflammatory Bowel Disease: A Multicenter North American Experience.

Background: Infliximab (IFX) infusion may lead to development of anti-IFX antibodies, and subsequent infusion reactions (IRs). The safety of rapid IFX infusion administered over 60 minutes has been under-investigated in children with inflammatory bowel disease. In a multicenter study, the frequency and nature of rapid infusion-associated IRs were examined.
