| Title | Risk of inflammatory bowel disease in uveitis patients: A population-based study |
| Purpose | To investigate the potential association between uveitis and an increased risk of developing Inflammatory bowel disease (IBD). |
| Methods | We conducted a retrospective cohort study by interrogating data from the Taiwan National Health Insurance Research Database entered between January 1, 2001, and December 31, 2013 to identify uveitis patients and age- and gender-matched controls. The cumulative incidence rates of subsequent IBD in the two groups were compared. The adjusted hazard ratio (HR) of IBD related to uveitis was generated by a multivariate cox regression model after adjustment for hypertension, diabetes, hyperlipidaemia, obesity and smoking. Furthermore, the HRs of the Crohn’s disease (CD) and ulcerative colitis (UC) IBD subtypes were calculated separately. |
| Results | A total of 198923 subjects with uveitis and 397846 controls were enrolled. The mean age of the cohort was 47.7 ± 18.9 years. A significantly higher cumulative incidence of IBD was found in the uveitis group than in controls (4.13% vs. 1.48%, p<0.0001). Under univariate cox regression analysis, uveitis patients had a significantly higher risk of IBD (HR= 1.47; 95% confidence interval [CI]:1.43-1.52, p<0.0001). The association remained significant in the multivariate regression model, with an adjusted HR of 1.44 (95% CI: 1.39 to 1.49, p<0.0001). Moreover, in subgroup analysis, uveitis was significantly associated with an increased risk of Crohn's disease (adjusted HR=1.49; 95% CI: 1.44-1.54), but not with ulcerative colitis (adjusted HR=1.03; 95% CI: 0.92–1.15). |
| Conclusion | Patients with uveitis are at significantly greater risk of developing IBD than individuals without uveitis. |
