Do Not Assume Symptoms Indicate Failure of Anti-Tumor Necrosis Factor Therapy in Crohn's Disease

It is a challenge to monitor patients with Crohn's disease who remain symptomatic despite anti-tumor necrosis factor therapy. Clinicians must use a systematic approach for each patient and obtain objective evidence about disease activity and response to therapy. Alternate etiologies for symptoms should be sought and treated, if found. Active Crohn's disease despite therapy requires reassessment and adjustments to management plans.
