Irritable Bowel Syndrome: Straightening the road from the Rome criteria

Area of Science:

• Gastroenterology
• Functional Gastrointestinal Disorders

Background:

• The Rome criteria for Irritable Bowel Syndrome (IBS) have undergone revisions since 1989.
• Key changes in Rome II and IV criteria involved symptom categorization and diagnostic frequency thresholds.

Purpose of the Study:

• To review the evolution of Rome criteria for IBS diagnosis.
• To highlight deficiencies in current symptom-based criteria and propose an alternative approach.
• To discuss the potential of biomarker identification for targeted IBS therapy.

Main Methods:

• Analysis of historical Rome criteria publications.
• Review of validation studies for consensus-based IBS criteria.
• Discussion of emerging research on actionable biomarkers for functional gastrointestinal disorders.

Main Results:

• Validation studies indicate limitations in the "splitting" of IBS subtypes.
• A simpler diagnostic model focusing on abdominal pain, bowel dysfunction, and bloating is favored.
• Biomarker research offers a pathway towards mechanism-based diagnosis and targeted treatment.

Conclusions:

• Current symptom-based IBS criteria face challenges, questioning the rationale for syndrome "splitting."
• A simplified diagnostic approach integrating core symptoms and excluding alarm features is recommended.
• Advancements in biomarker discovery promise a shift towards precision medicine in functional gastrointestinal disorders.
