Pathogenic Factors in Postinfectious Irritable Bowel Syndrome - An Update
Up to 30% of patients experience prolonged gastrointestinal issues post-gastroenteritis. New Rome IV criteria recognize postinfectious irritable bowel syndrome (PI-IBS) as a distinct entity linked to mucosal inflammation.
Area of Science:
- Gastroenterology
- Microbiology
- Immunology
Background:
- Acute infectious gastroenteritis can lead to persistent gastrointestinal symptoms in a significant patient subset.
- A portion of these patients meet diagnostic criteria for postinfectious irritable bowel syndrome (PI-IBS).
- Historically, PI-IBS diagnosis relied on the Rome III criteria.
Purpose of the Study:
- To outline the diagnostic evolution of PI-IBS.
- To highlight the impact of the Rome IV criteria on PI-IBS classification.
- To underscore the proposed underlying pathophysiology of PI-IBS.
Main Methods:
- Review of diagnostic criteria evolution for PI-IBS.
- Analysis of changes introduced by Rome IV criteria.
- Examination of the role of chronic mucosal inflammation in PI-IBS pathogenesis.
Main Results:
- The Rome IV criteria represent an update to the diagnostic standards for PI-IBS.
- PI-IBS is now recognized as a specific entity within the Rome IV framework.
- Chronic mucosal inflammation, triggered by enteric infection, is implicated in the persistent symptoms of PI-IBS.
Conclusions:
- The Rome IV criteria offer a refined approach to diagnosing PI-IBS.
- Understanding the role of mucosal inflammation is key to comprehending PI-IBS.
- This classification acknowledges the specific pathophysiology of PI-IBS following infection.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
