Antibody Patterns May Predict Inflammatory Bowel Disease Years Before Diagnosis
A machine learning model analyzed 2,000 serum samples from 500 people and predicted future IBD with high accuracy up to 10 years before diagnosis.
- Presented today at United European Gastroenterology Week 2026, a large-scale study identified distinct antibody patterns capable of predicting inflammatory bowel disease up to 10 years before diagnosis.
- Researchers analyzed 2,000 serum samples from 500 individuals, discovering that patients who later developed Crohn's disease or ulcerative colitis exhibited significantly lower antibody diversity compared to healthy controls.
- Using machine-learning models to integrate these early signatures, the team successfully discriminated individuals who would later develop IBD from healthy controls with AUC values of 0.90 and 0.84.
- Lead author Dr. Arno Bourgonje of the University Medical Center Groningen stated it is "fascinating to see" that complicated disease at diagnosis is associated with distinct profiles years before symptoms, not simply progression.
- These findings provide an initial proof of concept for future screening tests; researchers noted the immune response could one day support designing a flagellin-directed vaccine for high-risk individuals.

Antibody patterns may predict inflammatory bowel disease years before diagnosis
A large-scale study, presented today at UEG Week 2026, has identified distinct antibody patterns up to 10 years before the diagnosis of inflammatory bowel disease (IBD), potentially opening new avenues for earlier risk detection and providing insights into future disease course.
The immune system could launch alarm signals long before the onset of Crohn's symptoms and ulcerative colitis. A study identifies antibody profiles associated with the future...
A blood test could reveal Crohn’s disease years before symptoms
A new blood test may reveal Crohn’s disease years before symptoms begin. The test detects an unusual immune response to gut bacteria in people who later develop the condition. By studying healthy relatives of Crohn’s patients, researchers identified early warning signals long in advance. The findings raise hope for earlier diagnosis and future prevention.
Antibody patterns in people's blood could predict the onset of inflammatory bowel disease (IBD) a decade before diagnosis, according to a large-scale study. The finding could open up new avenues for early detection of the risk of developing the disease. Crohn's disease and ulcerative colitis, ... More www.ertnews.gr
