Gastroesophageal reflux disease (GERD) may cause otitis media with effusion (OME). However, whether treating GERD can benefit patients with OME has not been well studied.
We systematically searched PubMed, Embase, Cochrane Library, and Wanfang databases. The search period was from the establishment of the databases until December 31, 2022. Clinical studies related to GERD treatment on the outcomes of OME were included. Two reviewers independently conducted literature screening and data extraction according to the inclusion and exclusion criteria. To evaluate the quality of the included studies, we used the NOS assessment tool and the RevMan 5.4. Subgroup analysis was conducted to reduce the risk of heterogeneity, and Egger and Begg funnel plots were used to evaluate publication bias. Meta-analysis was performed using Stata14.0 and Review Manager 5.4 software.
Finally, 21,744 patients from 16 studies were included. The results showed that the rate of GERD in OME patients was 0.56 (95 % confidence interval (CI): 0.33, 0.79), while it was 0.04 (95 % CI: 0.03, 0.05) in the adult GERD population. The combined risk ratio (RR) of OME in patients with versus without GERD was 1.58 (95 % CI: 1.35, 1.85; p 0.05). The hearing loss cure rate was 0.70 (95 % CI: 0.57, 0.82).
GERD has been suggested to be a high-risk factor for OME. Treatment of GERD can improve the symptoms of OME. However, further studies are required to verify these findings.
