Post-infection irritable bowel syndrome following Coronavirus disease-19: A systematic review and meta-analysis.

Publication date: Jan 23, 2024

BACKGROUND AND OBJECTIVES: Persistent gastrointestinal (GI) symptoms and functional gastrointestinal disorders (FGIDs) are increasingly being recognized after Coronavirus disease-19 (COVID-19). Though quite a few studies addressed irritable bowel syndrome (IBS) following COVID-19, the disorders’ prevalence varies greatly. We evaluated, (i) overall frequency of post-COVID-19 IBS, (ii) relative risk of development of IBS among COVID-19 patients compared to healthy controls using systematic review and meta-analysis techniques. Literature search was performed for studies on GI symptoms and FGIDs after COVID-19 using electronic databases (Medline, Scopus, Cochrane Central Register of Controlled Trials, Google Scholar and Web of Science) till April 28, 2023. We included studies reporting IBS after COVID-19 with any duration of follow-up and any number of subjects. Studies on pediatric population and those not providing relevant information were excluded. Relative risk of development of IBS using Rome criteria among COVID-19 patients compared to healthy controls was calculated. Analysis was done using MedCalc (Applied Math, Mariakerke, Belgium, version 7. 2) and Comprehensive Meta-Analysis version 3. 3.070 (Biostat Inc. Englewood, NJ 07631, USA). Of the available studies, 13 (four case-control) reporting on IBS after COVID-19 met inclusion criteria. Among 3950 COVID-19 patients and 991 controls, 7. 2% of COVID-19 patients and 4. 9% of healthy controls developed IBS. Of the four case-control studies reporting post-COVID-19 IBS, patients with COVID-19 were 2. 65 (95% confidence interval [CI] 0. 538 to 13. 039) times more likely to have post-COVID-19 IBS as compared to healthy controls. Patients with COVID-19 are more likely to develop post-COVID-19 IBS than healthy controls. The heterogeneity of studies, different criteria used by various studies to diagnose post-COVID-19 IBS and some studies not meeting the six-month follow-up duration of the Rome criteria for diagnosing IBS are limitations of this systematic review.
