An international team led by University of Pittsburgh School of Medicine researchers has identified genetic markers associated with risk for ulcerative colitis.
The findings, which appear today as an advance online publication of the journal Nature Genetics , bring researchers closer to understanding the biological pathways involved in the disease and may lead to the development of new treatments that specifically target them.
Ulcerative colitis is a chronic, relapsing disorder that causes inflammation and ulceration in the inner lining of the rectum and large intestine. The most common symptoms are diarrhea (oftentimes bloody) and abdominal pain. Ulcerative colitis and Crohn's disease, another chronic gastrointestinal inflammatory disorder, are the two major forms of inflammatory bowel disease (IBD).
"Ulcerative colitis and Crohn's disease are chronic conditions that impact the day-to-day lives of patients," said senior author of the study Richard H. Duerr, M.D., associate professor of medicine and human genetics at the University of Pittsburgh School of Medicine and Graduate School of Public Health. "IBD is most often diagnosed in the teenage years or early adulthood. While patients usually don't die from IBD, affected individuals live with its debilitating symptoms during the most productive years of their lives."
