Objectives/Hypothesis To develop and validate the Reflux Symptom Score (RSS), a self‐administered patient‐reported outcome questionnaire for patients with laryngopharyngeal reflux (LPR). Study Design Prospective controlled study. Methods A total of 113 patients with LPR were enrolled and treated with diet and 3 months of pantoprazole, alginate, and/or magaldrate depending on the LPR characteristics (acid, nonacid, or mixed). Eighty asymptomatic individuals completed the study. Patients and controls completed the RSS twice within a 7‐day period to assess test‐retest reliability. Internal consistency was measured using Cronbach's α for the RSS items in patients and controls. Validity was assessed by comparing the baseline RSS with the Reflux Symptom Index (RSI) and Voice Handicap Index (VHI). Seventy‐seven patients completed the RSS at baseline and after 6 and 12 weeks of treatment to assess responsiveness to change. The RSS cutoff for determining the presence and absence of LPR was examined by receiver operating characteristic analysis. Results Test‐retest reliability (rs = 0.921) and internal consistency reliability (α = 0.969) were high. RSS exhibited high external validity indicated by a significant correlation with the RSI (rs = 0.831). Internal validity was excellent based on the higher RSS in patients compared with controls (P = .001). RSS, RSI, and VHI scores significantly improved from pre‐ to posttreatment, indicating a high responsiveness to change. RSS >13 can be considered suggestive of LPR‐related symptoms. RSS was not influenced by the occurrence of gastroesophageal reflux disease, LPR subtypes, or patient characteristics. Conclusions RSS is a self‐administered patient‐reported outcome questionnaire that demonstrates high reliability and excellent criterion‐based validity. RSS can be used in diagnosing and monitoring LPR disease. Level of Evidence 3b Laryngoscope, 130:E98–E107, 2020

“…1). LPR findings and symptoms were respectively evaluated with the French version of RSI and RFS [14]. The videolaryngostroboscopic findings were rated by a senior laryngologist using videolaryngostroboscopy (StrobeLED-CLL-S1, Olympus Corporation, Hamburg, Germany) in a blind manner regarding the patient complaints (RSI).…”

Objective: To compare symptoms, signs, and acoustical voice quality changes throughout the 6-month course of empirical treatment between laryngopharyngeal reflux (LPR) males and females. Materials and Methods: Forty clinically diagnosed LPR females and 40 males with a reflux finding score (RFS) > 7 and a reflux symptom index (RSI) > 13 were treated with pantoprazole and diet recommendations during 3 or 6 months according to their evolution. RSI, RFS, and acoustic parameters were assessed at baseline and 3 and 6 months posttreatment. A correlation analysis between videolaryngostroboscopic findings and acoustic measurements was performed. Results: RSI, RFS, and many acoustic measurements (i.e., percent jitter, percent shimmer, phonatory fundamental frequency range, fundamental frequency variation , and peak-to-peak amplitude variation) significantly improved from baseline to 3 months posttreatment in male group. In female group, RSI and RFS total score significantly improved along the 3 first months of treatment. However, some clinical outcomes (i.e., RSI total score, hoarseness, cough, and globus) continued to improve from 3 to 6 months of treatment. We did not identify significant improvement of acoustic measurements in female group. The correlation study did not reveal significant correlation between videolaryngostroboscopic findings and acoustic measurements. Conclusion: This preliminary study suggests the occurrence of gender-related differences in the LPR therapeutic response. Further studies need to clarify whether females require a longer course of therapy than males.

“…Seven studies were excluded due to overlapping patient populations. 78,[87][88][89][90][91][92] Two placebo RCTs included in previous meta-analysis 93 were excluded because focusing on patients with chronic cough attributed a posteriori to LPR. 94,95 The degree of agreement between investigators was high because only three articles have been discussed about the inclusion.…”

Objectives To investigate the therapeutic benefit of proton pump inhibitors (PPIs) over placebo in patients with laryngopharyngeal reflux (LPR) and to analyze the epidemiological factors of heterogeneity in the literature. Methods An electronic literature search was conducted to identify articles published between 1990 and 2018 about clinical trials describing the efficiency of medical treatment(s) on LPR. First, a meta‐analysis of placebo randomized controlled trials (RCTs) comparing PPIs versus placebo was conducted according to diet. The heterogeneity, response to PPIs, and evolution of clinical scores were analyzed for aggregate results. Second, a systematic review of diagnosis methods, clinical outcome of treatment, and therapeutic regimens was performed using the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses statement. Results The search identified 1,140 relevant publications, of which 72 studies met the inclusion criteria for a total of 5,781 patients. Ten RCTs were included in the meta‐analysis. The combined relative risk was 1.31 in favor of PPIs and increased to 1.42 when patients did not receive diet recommendations. Randomized controlled trials were characterized by a significant heterogeneity due to discrepancies in clinical therapeutic outcomes, diagnosis methods (lack of gold standard diagnostic tools), and therapeutic scheme. The epidemiological analysis of all articles supports the existence of these discrepancies in the entire literature. In particular, many symptoms and signs commonly encountered in LPR are not assessed in the treatment effectiveness. The lack of diagnosis precision and variability of inclusion criteria particularly create bias in all reported and included articles. Conclusion This meta‐analysis supports a mild superiority of PPIs over placebo and the importance of diet as additional treatment but demonstrates the heterogeneity between studies, limiting the elaboration of clear conclusions. International recommendations are proposed for the development of future trials. Laryngoscope, 129:1174–1187, 2019
