Discontinue 6-MP b. Discontinue Infliximab c. Discontinue both 2) If not normal: a. Discontinue 6-MP b. Discontinue Infliximab “STORI”: What happens when IFX is withdrawn? • Prospective multi-center study: GETAID • Patients with luminal CD, >17 y.o., who received at least 1 year of IFX plus AZA/6-MP/MTX • At least 2 infusions of IFX administered in preceding 6 months. Final IFX no more than 2 weeks after accrual. • Outcome: Steroid-free remission >6 months, CDAI <150. • CDAI at recruitment: 37 (19-61) Louis E et al.

What do these data mean for this patient? • Low-to-Intermediate risk of relapse – Male, no previous surgery – On immunomodulator – Normal CRP, hemoglobin • Options: – Stop IFX, continue 6-MP – Continue 6-MP, then stop IFX • Louis et al.: Re-treatment with IFX induced remission in 36/40 (96%) Treating the Outpatient with Severe IBD: Case Studies Corey A.

Uceris Anti-TNF Immunomodulator Vedolizumab Some combination of above Surgery Case: 67 year old gentleman with UC • Initiated on infliximab monotherapy (with prednisone 40mg daily) • Start to taper prednisone • Week 14 infliximab concentration = 11, negative antibody • But unable to taper below prednisone 20mg • Repeat colonoscopy with moderately active extensive colitis (no significant change) • Now what? Increase infliximab dose Add immunomodulator Change to vedolizumab Start smoking Surgery Cigarette Smoking in UC: Immunology • Immunologic mechanisms for the protective effect of cigarette smoking in UC remain unclear • Immunologic and clinical studies in IBD have focused on nicotine • Therapeutic trial experience in UC with nicotine gum, transdermal nicotine, enemas has been inconclusive One component of cigarette smoke, carbon monoxide (CO), possesses potent anti-inflammatory effects in numerous models of acute inflammation Otterbein L et al, Nat Med 2000;6:422-8 ALERT: “BAD AIR” CO as a Therapeutic?
