13 Natural history in elderly patients with younger age at-onset In elderly patients with disease onset at a younger age, a more aggressive presentation may still occur.Crohn's disease activity does not burn out with time, and roughly 25% of patients still have active disease 20 years after diagnosis.Etienney I et al.

15 PolypharmacyCross-sectional study of 128 IBD patients aged >65 years, patients were taking an average of 9.5 routine medications.Severe polypharmacy (>10 med) is associated with comorbidity index scores and steroid use, but not with disease activity or type.80% of patients had at least one medication interaction, with the majority involving IBD therapies (63%).CHECK for interactions before prescribing any IBD therapy in order to prevent potential adverse effectsParian AM et al.

22 Outline Epidemiology Special considerations Medical and surgical therapies in the elderlyTherapeutic strategies in the elderly
23 Specific concerns of medical therapy It is currently unknown if treatment goals in older patients should be different with regard to the need for clinical and endoscopic remission.There are no sweeping conclusions to be made from clinical trials since this aged population with comorbidities is excluded from almost all new drug development programs.
24 Specific therapeutic considerations 5-ASAsThe wide use of 5-ASAs among patients with elderly- onset CD is suggestive of a possible role in patients with mild CD.5-ASAs are effective for inducing and maintaining remission in UC and appear comparable in efficacy in both younger and older patients.Foam formulation of topical therapy and single daily dosing of oral 5-ASAs may improve compliance.Creatinine clearance should be monitored in the elderly every 6-12 months during therapy, especially when long-term high-dose regimens are used.Drug interactions with warfarin, 6-MP, AZASolberg IC, et al. Clin Gastroenterol Hepatol Dignass A et al. J Crohns Colitis 2012Muller AF, et al. Aliment Pharmacol Ther 2005
25 Specific therapeutic considerations CorticosteroidsThe use of corticosteroids carries the risk of precipitating or exacerbating pre-existing diabetes mellitus, congestive heart failure, hypertension, altered mental status and osteoporosis.Early bone densitometry, with repeated annual examinations, and vit D & calcium supplementation with > 12 weeks of steroids.Treatment with budesonide may be considered as it interferes less with bone metabolism; budesonide in UC.Drug interactions: phenytoin, phenobarbital, ephedrine, rifampin.Akerkar GA et al. Am J Gastroenterol 1997Dignass A et al. J Crohns Colitis 2010
26 Specific therapeutic considerations ImmunomodulatorsImmunomodulators should be considered in patients with corticosteroid dependence to maintain remission.In elderly patients with adequate kidney function, methotrexate should be considered as aging is a risk factor for lymphoma and skin cancer in patients exposed to thiopurines.Allopurinol use could potentially have a benefit in reducing the thiopurine dose but its concomitant use with immunomodulators increases the incidence of infection in older patients with lower absolute lymphocyte counts.Dignass A et al. J Crohn’s Colitis 2010Ansari A et al. Aliment Pharmacol Ther 2010Govani SM et al. J Crohns Colitis 2010Magro F et al. J Crohns Colitis 2013

32 Why surgery?More aggressive disease presentation at diagnosis in UC in the elderly?Suboptimal response to conventional therapy?Physicians’ concerns about recommending immunosuppressive agents for older patients with comorbidities?Disease recurrence tends to be lower postoperatively among elderly-onset CDHowever, time to recurrence may be shorter for older patientsWagtmans MJ et al. J Clin Gastroenterol 1998
33 SurgeryApproximately 25% of intestinal IBD surgeries are among pateints over the age of 55 years.Older age is associated with an eight-fold increased risk of in-hospital postoperative mortality, with bowel perforation and sepsis reported as leading causes of death.Older age is associated with an higher postoperative morbidityWhen considering surgical options:Consider pre-existing comorbidities – multidisciplinary careOptimization of their nutritional statusKaplan GG et al.

Ann Surg 2002Delaney CP et al. Ann Surg 2003Delaney CP et al. Dis Colon Rectum 2002
36 Proposed step-up medical therapy in elderly-onset IBD Biologic therapy is associated with a risk of severe infections in elderly patients with IBD.A step-up approach of adding therapies may be preferred over a top-down approach in elderly-onset IBD.Azathioprine should be avoided in patients >65 yearsIn patients requiring anti-TNF therapy for induction, monotherapy for maintenance of remission or association with methotrexate should be preferredBiologictherapyMethotrexate*>ThiopurinesAntibiotics / BudesonideCorticosteroids5-Aminosalicylates* In patients with CD
37 RED FLAGS Importance of nutritional status Chemoprophylaxis for opportunistic infectionsVaccinationDVT prophylaxis for hospitalized patientsAssess psychologic status & evaluate social support
38 ConclusionThere are many uncertainties regarding therapeutic strategies in the elderlyLack of efficacy and safety data from clinical trials in this population – often excludedRisks of misdiagnosisIncreased risk of side-effectsHigh rate of comorbiditiesPolypharmacyRecent evidence has outlined that the disease course of elderly-onset IBD is less aggressive than that in the younger population.This distinction should be considered when discussing therapeutic management in this complex population.
