Background
As the American population is aging, the number of older people with IBD is increasing. We used clinical data from the Sinai-Helmsley Alliance for Research Excellence (SHARE), a prospective cohort, to examine disease and treatment differences in older adults.
Methods
We performed a cross-sectional study assessing demographics and disease behavior by age at diagnosis with univariate, bivariate and multivariate analyses. “Older-onset” patients were diagnosed after age 60, “younger-onset” patients were diagnosed before age 60, but are older than 60 years and the remainder were “young”.
Results
There were 91 older-onset, 389 younger-onset and 3431 young Crohn's disease (CD) patients. Older-onset patients had more ileal (37%) and colonic (27%) disease compared to younger-onset and young patients. There were no differences in disease behavior, location or surgeries between older-onset and young CD patients within 5 years of diagnosis. Older-onset patients with inflammatory disease had a higher odds of being in remission. Young patients reported more anti-TNF and thiopurine use compared to younger-onset and older-onset patients (p <0.01). There were 98 older-onset, 218 younger-onset and 1702 young ulcerative colitis (UC) patients. There were no differences in disease extent, activity index or surgeries. Young UC patients reported more anti-TNF use (26%) compared to younger-onset patients (17%, p <0.01).
Conclusions
Disease behavior or location were not different between younger and older adults with IBD. Older patients were less likely to be treated with immunosuppression. If older patients have similar disease behavior, less frequent treatment with immunosuppressives may risk sub-optimally controlled disease.
