    Abstract:
    BACKGROUND: Few data are available regarding the evolution of Crohn's disease after discontinuing a successful course of infliximab. AIM: To evaluate clinical outcome of Crohn's disease after induction of remission with three infliximab infusions (luminal disease) and after maintenance of remission with 1-year course of infliximab every 8 weeks (luminal and perianal). METHODS: Twenty-three patients with active luminal Crohn's disease who responded to three infusions of infliximab (0, 2, and 6 weeks), and 23 patients with sustained response to infliximab every 8 weeks during 1 year, were included. Patients were followed-up until relapse or for at least 6 months after infliximab discontinuation. Clinical outcomes and factors associated to relapse were evaluated. RESULTS: In luminal Crohn's disease, a three-infusion infliximab regimen achieved a sustained response in most patients, especially if a complete response occurred at the time of the third infusion. In patients treated for 1-year, infliximab discontinuation was also successful, with a cumulative probability of being free of relapse of 69% at 12 months. In perianal disease, early relapse was the rule after stopping infliximab treatment, with only 34% of patient maintaining remission at 1 year. CONCLUSIONS: Short regimens of infliximab might be evaluated in patients with luminal Crohn's disease. However, infliximab discontinuation is not recommended in perianal Crohn's disease, because of a high rate of early relapse.
