Safety Considerations WithTNF Inhibitors • Infections • Lymphoma • Antibodies against the compound • Infusion/injection site reactions • Other • Autoimmunity and autoantibodies • Demyelination • Congestive heart failure (CHF) • Hematologic disorders • Liver toxicity
Evolving Goals in IBD Goals Perspective Society Clinician Patient Improved outcomes Normal laboratory data Remission off steroids Mucosal healing Improved signs, symptoms and quality of life Remission more than symptom control
Accomplishments in IBD • Shift in the treatment paradigm • Optimal use of Anti-TNF • Appropriate patient identification • Raising the bar for treatment standards • Steroid-free remission • Complete mucosal healing • Improved outcomes • Ultimately strive for changing the natural course of disease
