ECCO Recommendations
• Few data exist in using immunosuppressants (IS) in
IBD patients with prior cancer
• Recommended “waiting period” before IS starts ;
• 2 years for invasive cancers
• 5 years for aggressive cancers (lymphoma, melanoma,
breast, sarcomas, urinary tract cancers, and myeloma)

CASE #2
Crohn’s disease
• 27 yo man with a hx of ileocolonic Crohn’s
disease for 6 years
• 6-MP partial response, infliximab added
• Sustained remission for 4 years on dual
therapy
• He wants to discontinue all medications
• CRP/ESR normal
• All other routine labs are normal
You recommend:
A) Discontinue 6-MP
B) Discontinue Infliximab
C) Discontinue both
D) Colonoscopy or imaging
1) If normal:
a. 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“STORI”: What happens when IFX is withdrawn?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)

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

Case: 67 year old gentleman with UC
• 67 year old gentleman with recent onset of diarrhea
with bleeding
• 10-12x/day, up at night
• Stool studies (including C. diff) negative
• Colonoscopy and biopsies consistent with moderately
active extensive ulcerative colitis
Past medical history
• Hip osteoarthritis, s/p hip replacement
• Pneumonia 3 months prior
• Admitted to ICU, intubated
• Quit smoking at that time
Current meds: none other than occasional naproxen
Case: 67 year old gentleman with UC
• First treatment options in new diagnosis of moderately
active UC?
• Does “top down” apply to UC also?
• Initiated on prednisone 40mg daily + 4.8 grams of 5ASA, Rowasa nightly
• Unable to taper down below 20mg
• Now what?






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

Case: 41 year old woman with Crohn’s
disease
(2 scenarios)
• Diagnosed with ileal and perianal Crohn’s disease
• At diagnosis started on 6MP + Infliximab + Cipro
• Elevated LFTs – shunting with 6MP (despite
heterozygous TPMT – with half dosing!)
• Infliximab monotherapy – did GREAT
• Complete mucosal healing
• No further perianal lesions
• Asymptomatic
41 year old woman with Crohn’s disease
(2 scenarios)
• One year later – performed therapeutic drug monitoring
• Prometheus ANSER assay
• Infliximab trough concentration = 0
• Antibody level = 24
