PG - 47-59 LID - 10.1177/19458924231210028 [doi] AB - BACKGROUND: Over the last few decades, reflux diseases, such as laryngopharyngeal reflux (LPR) and gastroesophageal reflux disease (GERD), have been identified as significant contributors to inflammatory upper aerodigestive tract diseases. Establishing a direct relationship between reflux disease and chronic rhinosinusitis (CRS) is challenging due to the high prevalence of both diseases and their potential for independent coexistence. OBJECTIVE: The purpose of this study is to review the existing literature and evaluate the evidence of an association between reflux diseases and CRS. METHODS: A comprehensive electronic search was conducted across multiple databases to identify all studies that investigated the relationship between LPR, GERD, and CRS from January 1, 1950, to June 16, 2022. Only studies with English manuscripts involving adult populations were included, while case series, case reports, and in vitro studies were excluded. The risk of bias was evaluated using The Newcastle-Ottawa Scale for case-control studies and the NIH quality assessment tool for observational cohort and cross-sectional studies. RESULTS: The search strategy yielded a total of 427 articles, out of which 25 studies examined the correlation between reflux diseases and CRS. The meta-analysis indicated a significant association between the presence of GERD and CRS compared to control groups (P < .001; CI 3.56 [2.25, 5.65]), as well as significantly higher pH values and pepsin detection in CRS patients when compared to healthy individuals (P = .003). Furthermore, all studies that evaluated proton pump inhibitor (PPI) therapy in CRS patients reported positive outcomes, with 93% of CRS patients showing improvement on PPIs. CONCLUSION: The existing literature provides suggestive evidence of an association between reflux diseases and CRS, with regards to both prevalence and treatment. Nonetheless, further studies are required to confirm this relationship.
