It is not too much to say that infliximab has revolutionized the treatment of Crohn's disease. However, there is the problem of 'secondary failure' wherein the effect may diminish during treatment. This is a much-discussed topic. For example, not all patients with secondary failure can maintain remission with dose intensification to 10 mg/kg. It is also important to make the appropriate drug selection and to clarify the optimal timing of dose intensification for achieving long-term maintenance of remission, including discussion of the first priority use of adalimumab.
