- Background and Aims: We aimed to compare the risk of frailty in older adults with incident inflammatory bowel disease (IBD) and matched non-IBD comparators and assess the association between frailty and future hospitalizations and mortality.Methods: In a cohort of patients with incident IBD ≥60 years of age from 2007 to 2016 in Sweden identified using nationwide registers, we defined frailty using Hospital Frailty Risk Score. We compared prevalence of frailty in patients with IBD with age, sex, place of residency– and calendar year–matched population comparators. In the IBD cohort, we used Cox proportional hazards modeling to examine the associations between frailty risk and hospitalizations or mortality.Results: We identified 10,590 patients with IBD, 52% female with a mean age of 71 years of age, matched to 103,398 population-based comparators. Among patients with IBD, 39% had no risk for frailty, 49% had low risk for frailty, and 12% had higher risk for frailty. Mean Hospital Frailty Risk Score was 1.9 in IBD and 0.9 in matched comparators (P < .01). Older adults with IBD at higher risk for frailty had a 20% greater risk for mortality at 3 years compared with those who were not frail. Compared with nonfrail older patients with IBD, patients at higher risk for frailty had increased mortality (hazard ratio [HR], 3.22, 95% confidence interval [CI], 2.86–3.61), all-cause hospitalization (HR, 2.42; 95% CI, 2.24–2.61), and IBD-related hospitalization (HR, 1.50; 95% CI, 1.35–1.66). These associations were not attenuated after adjusting for comorbidities.Conclusions: Frailty is more prevalent in older adults with IBD than in matched comparators. Among older patients with IBD, frailty is associated with increased risk for hospitalizations and mortality.

- BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) has been associated with spondyloarthritis (SpA), but population-based estimates are scarce. Here we compare the occurrence of SpA before and after a diagnosis of IBD to the general population, overall and by IBD subtype and age.METHODS: We used a nationwide register-based cohort study of 39,203 patients diagnosed with IBD during 2006-2016, identified from Swedish registers and gastrointestinal biopsy data, and 390,490 matched reference individuals from the general population. Conditional logistic regression models were used to estimate odds ratios (ORs) for a prior (prevalent) SpA diagnosis and conditional Cox regression to calculate hazard ratios (HRs) for a subsequent (incident) SpA diagnosis in IBD patients.RESULTS: IBD patients were more likely to have prevalent SpA at IBD diagnosis (2.5%) compared to reference individuals (0.7%) with an OR of 3.48 (95%CI:3.23-3.75). They also more often received an incident diagnosis of SpA; during 23,341,934 person-years of follow-up in IBD patients, there were 1,030 SpA events (5.0/1,000 person-years) compared to 1,524 SpA events in the reference group (0.72/1,000 person-years), corresponding to an HR of 7.15 (95%CI:6.60-7.75). In subgroup analyses, associations were most pronounced among patients with Crohn's disease [(OR=5.20; 95%CI:4.59-5.89), and (HR=10.55; 95%CI:9.16-12.15)] and paediatric onset IBD [(OR=3.63; 95%CI:2.35-5.59) and (HR=15.03; 95%CI:11.01-20.53)].CONCLUSION: IBD patients more frequently experience SpA both before and after the diagnosis of IBD compared to the general population, supporting evidence of a shared pathophysiology. The variation in SpA comorbidity across IBD subtypes and age-groups, calls for targeted approaches to facilitate timely diagnosis and intervention.
