Objective To explore the correlation between laryngopharyngeal reflux (LPR) and allergic rhinitis (AR).Methods Seventy-two patients with suspected LPR who visited our outpatient department of otolaryngology between June 2019 and June 2020 were included. All the patients were divided into LPR positive group and LPR negative group according to their 24 hDx-pH monitoring results. The diagnosis of AR was established via score for allergic rhinitis (SFAR)(SFAR≥7).The prevalence rate of AR in LPR positive and negative groups was compared, and the correlation between Dx-pH and SFAR scores was studied.Results Of the 72 patients, the diagnosis of AR was established in 40, including 22 in the LPR positive group (32 cases) and 18 in the LPR negative group (40 cases). The SFAR score of LPR positive group was significantly higher than that of LPR negative group (P<0.05). The prevalence rate of AR in the LPR positive group was higher than that of the negative group (P<0.05).Conclusion The SFAR score of LPR positive group is higher than that of the LPR negative group, which suggests that LPR and AR may be relevant.
