In new evidence-based guidelines, the American Gastroenterological Association (AGA) recommends non-invasive biomarkers as a first-line strategy for monitoring many patients with ulcerative colitis (UC). These guidelines were published today in Gastroenterology.
The AGA guidelines outline use cases for three biomarkers that provide accurate insights into ulcerative colitis disease activity: serum C-reactive protein (CRP) (blood), fecal calprotectin (stool) and fecal lactoferrin (stool).
"For decades we have regarded endoscopy as the gold standard for monitoring ulcerative colitis and detecting bowel inflammation, but repeated endoscopic assessment is invasive, expensive and often impractical," says guideline author Siddarth Singh, MD, MS, University of California, San Diego. "Not only are biomarkers accurate, but they provide patients with a cheaper and more convenient option of monitoring to ensure medications are working and ultimately keeping their disease well-managed."
AGA recommends a monitoring strategy that integrates non-invasive biomarkers for patients with ulcerative colitis in remission (no current symptoms) as well as those with current symptoms.
With AGA guidelines guiding the use of noninvasive biomarkers, physicians can confidently offer a more convenient and closer monitoring option for their patients.
"Currently biomarkers are considered experimental by insurers," adds guideline author Ashwin N. Ananthakrishnan, MBBS, MPH, Massachusetts General Hospital. "This guideline is a major step in showing the value of noninvasive biomarkers and the importance of insurers covering biomarker monitoring to improve patient satisfaction and clinical outcomes."
AGA will advocate for all insurers to cover the cost of biomarker testing in ulcerative colitis.
Ulcerative colitis is one of the two main types of inflammatory bowel diseases and is more common than Crohn's disease. It causes inflammation (swelling) and sores (called ulcers) in the large intestine (colon and rectum) and may affect part or all the large intestines. Ulcerative colitis can happen at any age, but it is more likely to develop in people between the ages of 15 and 30, or older than 60 years of age.
