Inflammatory bowel disease in the elderly - Practical treatment guidelines

Although Crohn's disease and ulcerative colitis were initially described in young adults, it has become increasingly apparent that inflammatory bowel disease (IBD) affects the elderly, with the new onset of disease occurring well into the seventh and eighth decades of life. The diagnosis of IBD in the elderly may be difficult because it can be easily confused with infectious, ischaemic and drug-related processes, as well as with diverticulitis and carcinoma. Although medical treatment for IBD is similar in the young and the elderly, consideration must be given to comorbid illnesses in the older patient. Topical agents should be used as first-line therapy for patients with distal colonic disease. In patients with more proximal involvement, oral mesalazine or sulfasalazine should be used for maintenance therapy, with corticosteroids being reserved for patients with active disease. Metronidazole is particularly efficacious in patients with colonic Crohn's disease. Finally, immunomodulators can be helpful in patients who are steroid-dependent or refractory to the therapies noted above. This article reviews and outlines practical treatment guidelines for the older patient with IBD.
