Case A. - 42 yr old male patient
• Left-sided ulcerative colitis for 4 years• In clinical remission on mesalamine 4.8g/day
• Admitted for flare-up January 2013 – Rx IV steroids and discharged on PO prednisone taper
• Clinic follow-up – slow to taper off prednisone, azathioprine added, tolerated well
• Seen in office visit complaining of fatigue; started on oral ferrous sulfate 100mg by primary care physician

• Increase in serum ferritin - 84, 95% (CI 79, 92) p>0.001
• Risk of withdrawal due to adverse events RR 2.7 (CI 1.4, 5.2) p=0.002

Erythropoietin for Anemia in IBD
Schreiber s N Engl J Med. 1996 Mar 7;334(10):619-23
Guidelines – ECCO 2013
• “Iron supplementation should be initiated when iron deficiency anemia is present, and considered when there is iron deficiency without anemia
• Intravenous iron is more effective and better tolerated than oral iron supplements
• Absolute indications for intravenous iron include severe anemia (hemoglobin < 10.0 g/dL), and intolerance or inadequate response to oral iron
• Intravenous iron should be considered in combination with an erythropoietic agent in selected cases where a rapid response is required”

Case B. - 59 year old male
• Colonic Crohn’s for 20 years• Developed lymphoma while on azathioprine
• Recent flare-up; 4-6 BM per day, cramps• Rx budesonide & metronidazole
• Call from PCP – in local ED with frank rectal bleeding, and swollen left leg
• Ultrasound – left leg Deep Venous Thrombosis (DVT)
Sigmoidoscopy
What would you suggest next?

Venous Thromboembolism in IBD – A ‘Preventable Complication’
• 1-2% of all IBD hospitalizations
• Out-patients have 8-fold higher risk of VTE during flares, than when in remission
• Risks: age, UC, surgery, smoking, oral contraceptives
• Less than 40% of GIs ‘always’ prescribe VTE prophylaxis

VTE Prevention in IBD
• AGA Physician Performance Measures Set 2011;
‘Measure # 9: Patients with IBD receive prophylaxis for venous thromboembolism during hospitalization for any reason.’
• LMW / UF heparin• Compression stockings• Minimizing IV catheter use• Address smoking, OCP use, immobility
• ?Out-patient flares also
