MedPage Today (5/16, Bankhead) reports, “Women with psoriasis had a four-fold increase in the risk of Crohn’s disease, according to data from two large cohort studies” presented at the Society for Investigative Dermatology meeting. “The Crohn’s risk held up in separate analyses of the two studies and in a combined analysis of data from both cohorts,” whereas “psoriasis did not increase the risk of ulcerative colitis in either of the individual cohorts or in the combined analysis.”
