Background: The Rome IV irritable bowel syndrome (IBS) criteria include changes to the description and frequency of abdominal pain. Existing studies have demonstrated a lower prevalence and greater severity in IBS patients identified using Rome IV than Rome III criteria. Our aim was to investigate the prevalence of post-infection IBS (PI-IBS) using Rome IV criteria in a population-based cohort of laboratory-confirmed C. jejuni infection cases. Methods: The Minnesota Department of Health (MDH) requires notification of Campylobacter cases and interviews patients to gather information on clinical symptoms. For this study, the Rome IV diagnostic questionnaire was utilized 6–9 months after infection to determine the development of PI-IBS. The survey responses were analyzed for the prevalence of IBS and symptom severity. Key Results: Surveys were completed by 391 participants (31% response rate). Twenty-three patients had pre-existing IBS, and 18 did not complete enough questions to categorize their case status. Of the 350 remaining participants, 58 (17%) met Rome IV criteria. An additional 47 patients would have met the Rome III IBS criteria for pain frequency, driving the cumulative prevalence to 30%. The mean IBS Symptom Severity Score (IBS-SSS) in Rome IV patients was significantly higher than in Rome III (p < 0.05). With Rome IV, IBS-diarrhea was the most common subtype. Conclusions & Inferences: Rome IV criteria resulted in a 19% lower prevalence of PI-IBS than earlier reported Rome III-based prevalence in a similar population. Rome IV defined PI-IBS patients have greater symptom severity but similar distribution of IBS subtypes.
