HealthDay News — There appears to be a link between hidradenitis suppurativa (HS) and inflammatory bowel disease (IBD), according to a review published in the February issue of the International Journal of Dermatology.

Kevin Phan, M.D., from the University of New South Wales in Sydney, and colleagues conducted a systematic literature review to identify studies evaluating the association between HS and IBD.

Based on six included studies, the researchers observed a significant association between HS and IBD. When data were pooled in a meta-analysis, the adjusted effect sizes showed an odds ratio of 2.12. There was a significant association between HS and both Crohn disease (odds ratio, 2.25) and ulcerative colitis (odds ratio, 1.56).
