INTRODUCTION: Inflammatory bowel disease has classically been considered a disorder with onset in young people. However, between 5 and 15% of patients are diagnosed when aged more than 60 years old. Epidemiological studies comparing these two age groups are controversial and consequently new studies are required to define the characteristics in each group. OBJECTIVES: To determine the epidemiological characteristics specific to Crohn's disease and ulcerative colitis in the elderly and to compare these characteristics with the form of presentation in young people in Spain. METHOD: We performed a case-control, descriptive study. Patients with inflammatory bowel disease registered in the database of the Crohn-Colitis Unit were included. The patients were stratified in two groups according to age at symptom onset: the first group consisted of patients with onset at age 60 years or above and the second group was a control group consisting of patients aged less than 60 years old. The control group was composed of two patients for each case matched by sex and diagnosis. RESULTS: Thirty-three cases aged more than 60 years old (4.1%) were included, eight with Crohn's disease and 25 with ulcerative colitis. The control group included 66 patients (16 with Crohn's disease and 50 with ulcerative colitis). Statistically significant differences were observed between the two groups both in the form of presentation (tenesmus and occlusive symptoms were more frequent and abdominal pain was less frequent in the group aged more than 60 years than in the control group) and in treatment response (corticosteroid dependency and refractoriness and requirement for immunosuppressive treatment were more frequent in the elderly). CONCLUSION: The results of the present study suggest that there are epidemiological differences in inflammatory bowel disease among the elderly, notably a lower frequency of abdominal pain and a lower rate of refractoriness to steroid treatment.
