A patient with infantile-onset Crohn's disease had a partial response to corticosteroid therapy that worsened on its tapering, leading to treatment with antitumor necrosis factor-alpha monoclonal antibody therapy. Infliximab rapidly cleared before administration of the third accelerated induction dose with the development of antibodies. Adalimumab was initiated with a good clinical effect but also rapidly cleared, requiring dose intensification to improve drug levels and to maintain a good clinical response. The amount of medication could eventually be decreased. Accelerated induction and maintenance drug monitoring can prevent secondary loss of response in very young children with inflammatory bowel disease.
