Recent studies suggest that irritable bowel syndrome (IBS) is associated with low-grade inflammation. This study aims to determine the distribution of Helicobacter pylori cytotoxin-associated gene A (cagA) and vacuolating cytotoxin A (vacA) alleles (e.g., s1 and s2) in Patients with diarrhoea-dominant IBS (IBS-D) as the latter causes vacuolation in colonic epithelial cells in vitro. One hundred and seventy Patients meeting Rome III criteria for IBS-D (mean age: 40 +/- 15 years) were enrolled. Gastric biopsy was assessed histologically and DNA extraction was performed by polymerase chain reaction (PCR) for H. pylori genus 16S ribosomal DNA (16S rDNA), cagA and vacA …
