title: Optimizing the use of biological therapy in patients with inflammatory bowel disease.
abstract: Biological therapy revolutionized the treatment of inflammatory bowel disease (IBD) during the last decade. These monoclonal antibodies, which target tumor necrosis factor (TNF), integrins or IL12/23, have been approved-or are in development for-both Crohn's disease (CD) and ulcerative colitis (UC). Early use of these agents taught clinicians that induction and maintenance therapy, coupled with immunomodulator agents, reduced the immunogenicity of these agents, and led to sustained remission in many patients. More recent data has demonstrated that, through dose adjustments, optimizing serum drug levels may also provide more durable maintenance of remission, and improved mucosal healing. This review examines clinical practices that may enhance clinical outcomes from biological therapy in IBD.
