IBD Increases Risk of Stroke
Despite a lower prevalence of traditional risk factors-such as hypertension and diabetes-patients with inflammatory bowel disease (IBD) have a higher incidence of stroke, said researchers at the University of Miami.

In this retrospective cohort study, 356 patients with a diagnosis of IBD were compared with 712 matched controls. The primary outcome was the development of a cerebrovascular accident (CVA), defined as an acute neurological event accompanied by corresponding radiologic abnormality on CT and/or MRI; both ischemic and hemorrhagic events were included.
The incidence of CVA in the IBD cohort was 9.52 events per 1000 person-years, compared with 5 per 1000 person-years in the control group (P < .01). Hypertension, diabetes, and dyslipidemia were significantly more common among controls than among patients with IBD (P < .01); however, there was no significant difference in smoking status (P = .26). The odds ratio for the risk of stroke in the IBD cohort was 2.33 (95% CI [1.14 –4.72], P = .005).
The researchers suggest that premature development of atherosclerosis and hypercoagulability in patients with IBD may be responsible for the increased incidence of CVA.
