BACKGROUND: The incidence and prevalence of inflammatory bowel diseases (IBD) in older adults are rising. There is a limited comparative assessment of risk of disease- and treatment-related complications in older patients (older than 60 years) with adult-onset (age at disease onset, 18-59 years; AO-IBD) vs elderly-onset IBD (age at disease onset, older than 60 years; EO-IBD). We compared clinical outcomes in older patients with IBD with AO-IBD vs EO-IBD.
METHODS: We conducted a retrospective cohort study comparing risk of disease-related complications (IBD-related surgery, hospitalization, treatment escalation, clinical flare, or disease complication) and treatment-related complications (serious infection, malignancy, or death) in older patients with AO-IBD vs EO-IBD through Cox proportional hazard analysis, adjusting for age at cohort entry, disease phenotype, disease duration, prior surgery and/or hospitalization, medication use, disease activity at cohort entry, and comorbidities.
RESULTS: We included 356 older patients with IBD (AO-IBD, 191 patients, 67 ± 5 y at cohort entry; EO-IBD, 165 patients, 72 ± 8 y at cohort entry). No significant differences were observed in the risk of disease-related complications in older patients with prevalent vs incident IBD (adjusted hazard ratio [aHR], 0.85; 95% CI, 0.58-1.25), although risk of IBD-related surgery was lower in older patients with prevalent IBD (aHR, 0.47; 95% CI, 0.25-0.89). Older patients with prevalent IBD were significantly less likely to experience treatment-related complications (aHR, 0.58; 95% CI, 0.39-0.87).
CONCLUSION: Patients with AO-IBD have lower risk of treatment-related complications as they age compared with patients with EO-IBD, without a significant difference in risk of disease-related complications.
