Patients with inflammatory bowel disease (IDS) are more likely to be diagnosed with multiple sclerosis (MS), according to a study published in this month's Gastroenterology.
The research, undertaken by scientists at the University of Pennsylvania, found a nearly two-fold increase in risk of MS in people who suffered from IDS.
Previously, it was only believed patients being treated with anti-TNT alpha therapies were at risk of developing MS.
Study author James D. Lewis, MD, MSCE, said: "The development of neurologic symptoms in patients with IBD should prompt their physician to look for evidence of multiple sclerosis and other nervous system disorders."
The results were found when the study identified more than 20,000 patients from the UK's database diagnosed with Crohn's disease and ulcerative colitis.
Each subject then was compared to four controls, revealing the odds of being diagnosed with MS and other demyelinating disorders was 1.7 times as high as those with IBD.
