Abstract
PURPOSE Laryngopharyngeal reflux disease (LPRD) is mainly treated with proton pump inhibitors (PPI) such as esomeprazole, which have shortcomings like delayed absorption and increased osteoporosis. Fexuprazan is a novel potent potassium-competitive acid blocker that inhibits gastric acid secretion with rapid onset and long duration of action. To assess the efficacy and safety of fexuprazan compared to esomeprazole in patients with LPRD. METHODS This prospective, randomized, double-blinded, multicenter, active-controlled trial was conducted in nine otolaryngologic clinics. Patients with reflux symptom index (RSI) ≥ 13 and reflux finding score (RFS) ≥ 7 were randomly assigned to the fexuprazan or esomeprazole groups, and received fexuprazan 40-mg or esomeprazole 40-mg once daily for 8 weeks. The outcomes were (1) mean change, change rate, and valid rate in RSI, RFS, and LPR-related questionnaires; and (2) adverse events. RESULTS A total of 136 patients (fexuprazan n = 68, esomeprazole n = 68) were followed up for ≥ 1 month. Each parameter significantly improved after 4 and 8 weeks in each group, with no significant differences between the two groups. For those with severe symptoms (RSI ≥ 18), the fexuprazan group (n = 32) showed more improvement in the mean change and change rate in the RSI than esomeprazole group (n = 31) after 4 weeks (p = .036 and .045, respectively). This phenomenon was especially observed in hoarseness and troublesome cough. CONCLUSION Fexuprazan improved symptoms and signs without no serious adverse events in patients with LPRD. In patients with severe symptoms, fexuprazan resulted in a faster symptom improvement than PPI. TRIAL REGISTRATION KCT0007251, https://cris.nih.go.kr/cris/search/detailSearch.do?seq=22100 .

Abstract
Laryngopharyngeal reflux (LPR) manifests as a variety of nonspecific upper aerodigestive tract symptoms. Rather than a single disorder, LPR may be conceived of as a spectrum of subtypes with varying clinical presentations. LPR signs and symptoms arise from the direct and/or indirect effects of refluxate, physical and molecular injury of the mucosa, and neurologic responses to esophageal events. Specific constituents of refluxate exert distinct mucosal responses and immediate or delayed effects resulting in transient or persistent symptoms and/or laryngeal hypersensitivity. While the complex etiology of LPR presents challenges to its diagnosis and management, tools that aid the identification of LPR subtypes can provide insight into treatment decision-making. Hypopharyngeal-esophageal multichannel intraluminal impedance-pH monitoring provides detailed analysis of reflux events, enabling the development of individualized treatment plans, yet cost and availability limit its widespread use. Alginates offer temporary symptom relief and antireflux surgery may provide benefit when symptoms are recalcitrant to other approaches. Pepsin inhibitors hold promise as a medical therapy when surgery is not an option. Laryngeal hypersensitivity should be considered as part of a comprehensive therapeutic approach. Promising medical and scientific research continues to yield new insights into the complex etiology of LPR and novel strategies for its diagnosis and management.

Abstract
OBJECTIVE Height has the strongest correlation with esophageal length among the external anthropometric indices. Based on the association between laryngopharyngeal reflux (LPR) and the upper esophageal sphincter, this study aimed to investigate the relationship between height and LPR. METHODS Retrospective chart analysis of patients who visited an outpatient clinic with symptoms of LPR and underwent a 24-hour hypopharyngeal-esophageal multichannel intraluminal impedance-pH (24-hr HEMII-pH) monitoring. The study analyzed the relationship between height and LPR by (1) in total of 219 patients, (2) in males and females, and (3) in patients under age 60 and over age 60. RESULTS The relationship between height and LPR was analyzed for a total of 219 patients. There was no statistical significance between the number of pharyngeal reflux episodes and the height of subjects. When same analysis was done according to gender, the number of pharyngeal reflux episodes decreased as height increased in males, which was statistically significant, but not in females. Further analysis was done according to age in male and female, respectively. In male under age 60, there was statistical significance between the number of pharyngeal reflux episodes and the height of subjects, but not in over age 60. Also, in female under age 60 and over age 60, there was no statistical significance between the number of pharyngeal reflux episodes and the height of subjects. CONCLUSIONS This study suggests a correlation between height and pharyngeal reflux events in males and individuals under 60 years old tested with the 24-hr HEMII-pH monitoring.

Abstract
OBJECTIVES We aimed to evaluate the treatment outcomes of proton-pump inhibitors (PPIs) in patients with contact granuloma (CG) and to investigate the parameters of 24 h combined dual channel pH/impedance (24 h pH/MII) monitoring, which are reliable for predicting the response to PPI of CG patients. METHODS We reviewed the medical records of patients with CG who had been treated with PPIs and had completed more than 6 months of follow-up. We classified the patients into two groups (cured vs. persistent), according to their PPI treatment outcomes. Reflux events were categorized into three groups based on pharyngeal pH during reflux: 1) acid reflux (pH < 4), 2) weak acid reflux (4 < pH < 7), and 3) weak alkaline reflux (pH >7), as detected by a proximal probe. We compared the results of 24h-pH/MII between the two groups and used receiver operating characteristic curve (ROC) analysis to determine the cutoff values of significant parameters for predicting responses to PPIs. RESULTS Among 22 patients who completed at least 6 months of PPI treatment and follow-up, weak acid reflux events were more frequently observed in persistent group than in the cured group (p = 0.046), and the proportion of weak acid reflux was also higher in the persistent group (p = 0.031) than in the cured group. Reliable parameters predictive of a poor response to PPIs were a number of weak acid reflux events ≥ 11 (area under the curve [AUC], 0.775; p = 0.03) and a proportion of weak acid reflux events ≥ 56.7 % (AUC, 0.763; p = 0.038) in ROC analyses. CONCLUSION Weak acid reflux was identified as a significant factor associated with the treatment outcomes of PPIs in patients with CG. A number of weak acid reflux events ≥ 11 is considered to be the most reliable predictor of a poor response to PPIs in patients with CG.

Abstract
Laryngopharyngeal reflux disease (LPRD) is an inflammatory condition in the laryngopharynx and upper aerodigestive tract mucosa caused by reflux of stomach contents beyond the esophagus. LPRD commonly presents with sym-ptoms such as hoarseness, cough, sore throat, a feeling of throat obstruction, excessive throat mucus. This complex condition is thought to involve both reflux and reflex mechanisms, but a clear understanding of its molecular mechanisms is still lacking. Currently, there is no standardized diagnosis or treatment protocol. Therapeutic strategies for LPRD mainly include lifestyle modifications, proton pump inhibitors and endoscopic surgery. This paper seeks to provide a comprehensive overview of the existing literature regarding the mechanisms, patho-physiology and treatment of LPRD. We also provide an in-depth exploration of the association between LPRD and gastroesophageal reflux disease.

Abstract
OBJECTIVES To analyze pre to posttreatment voice changes regarding the type of reflux in patients with acid, weakly acid or alkaline laryngopharyngeal reflux (LPR). METHODS Patients with LPR, diagnosed using hypopharyngeal-esophageal multichannel intraluminal impedance pH-monitoring (HEMII-pH), were prospectively recruited from three University Hospitals. Patients were treated with a combination of diet, proton pump inhibitors, magaldrate and alginate for 3 months. The following clinical and voice quality outcomes were studied pre to posttreatment according to the type of reflux (acid, weakly acid, nonacid): HEMII-pH, gastrointestinal endoscopy features, reflux symptom score (RSS), reflux sign assessment (RSA), voice handicap index (VHI), perceptual voice assessment (grade of dysphonia and roughness), aerodynamic and acoustic measurements. RESULTS From December 2018 to March 2021, 160 patients completed the evaluations, accounting for 60 acid, 52 weakly acid, and 48 alkaline cases of LPR. There were no baseline differences in clinical and voice quality outcomes between groups. RSS and RSA significantly improved from pre to posttreatment in the entire cohort and in all patient groups. VHI, dysphonia and roughness, maximum phonation time, Jitter, Shimmer and noise to harmonic ratio significantly improved from pre to posttreatment. Individuals with alkaline reflux reported better voice quality improvements as compared to acid and weakly acid reflux patients. CONCLUSION Patients with acid and alkaline reflux reported better posttreatment voice quality outcomes as compared to weakly acid reflux patients. Future basic science and clinical studies are needed to better understand the histological changes of the vocal folds due to reflux of varying pH types and gastroduodenal enzyme content.

Abstract
Objectives Approximately 25% of Americans suffer from laryngopharyngeal reflux (LPR), a disease for which no effective medical therapy exists. Pepsin is a predominant source of damage during LPR and a key therapeutic target. Fosamprenavir (FOS) inhibits pepsin and prevents damage in an LPR mouse model. Inhaled FOS protects at a lower dose than oral; however, the safety of inhaled FOS is unknown and there are no inhalers for laryngopharyngeal delivery. A pre-Good Lab Practice (GLP) study of inhaled FOS was performed to assess safety and computational fluid dynamics (CFD) modeling used to predict the optimal particle size for a laryngopharyngeal dry powder inhaler (DPI). Methods Aerosolized FOS, amprenavir (APR), or air (control) were provided 5 days/week for 4 weeks (n = 6) in an LPR mouse model. Organs (nasal cavity, larynx, esophagus, trachea, lung, liver, heart, and kidney) were assessed by a pathologist and bronchoalveolar lavage cytokines and plasma cardiotoxicity markers were assessed by Luminex assay. CFD simulations were conducted in a model of a healthy 49-year-old female. Results No significant increase was observed in histologic lesions, cytokines, or cardiotoxicity markers in FOS or APR groups relative to the control. CFD predicted that laryngopharyngeal deposition was maximized with aerodynamic diameters of 8.1-11.5 μm for inhalation rates of 30-60 L/min. Conclusions A 4-week pre-GLP study supports the safety of inhaled FOS. A formal GLP assessment is underway to support a phase I clinical trial of an FOS DPI for LPR. Level of Evidence NA.

Abstract
A simple and effective pepsin detection assay is reported based on a pepsin-susceptible peptide (PSP) reporter degradation strategy. PSP, which can be specifically cleaved by pepsin, was modified with fluorescein isothiocyanate (FITC) and biotin at the N- and C-terminals to be used as a reporter for colorimetric detection of dipsticks. A universal lateral flow dipstick consisting of a streptavidin test line for biotin binding and a sample pad immobilized with a gold-labeled polyclonal (rabbit) anti-FITC antibody was used to verify PSP-based pepsin detection. When the PSP reporter reacts with pepsin in a tube, it cleaves into two fragments, and the cleaved fragments do not display any color on the test line. Therefore, the higher the concentration of pepsin is, the greater is the decrease in test line intensity (IT-line) and the higher is the control line intensity (IC-line). First, the PSP cleavage and dipstick assay conditions for pepsin detection was optimized. The ratio of color intensity (IT-line/IC-line) of PSP-based dipstick assay showed a linear relationship with log concentration of pepsin ranging between 4 and 500 ng/mL (R2 = 0.98, n = 6), with a limit of detection of 1.4 ng/mL. It also exhibited high specificity and good reproducibility. Finally, pepsin levels were quantified in saliva samples from healthy controls (n = 34) and patients with laryngopharyngeal reflux (LPR, n = 61). Salivary pepsin levels were higher in patients with LPR than in healthy controls. The salivary pepsin levels correlated with those measured using a conventional enzyme-linked immunosorbent assay kit. Therefore, this PSP-based dipstick assay is a convenient tool for assessing salivary pepsin levels.

Abstract
Laryngopharyngeal reflux (LPR) is a variant of gastroesophageal reflux disease (GERD) in which gastric refluxate irritates the lining of the aerodigestive tract and causes troublesome airway symptoms or complications. LPR is a prevalent disease that creates a significant socioeconomic burden due to its negative impact on quality of life, tremendous medical expense, and possible cancer risk. Although treatment modalities are similar between LPR and GERD, the diagnosis of LPR is more challenging than GERD due to its non-specific symptoms/signs. Due to the lack of pathognomonic features of endoscopy, mounting evidence focused on physiological diagnostic testing. Two decades ago, a dual pH probe was considered the gold standard for detecting pharyngeal acidic reflux episodes. Despite an association with LPR, the dual pH was unable to predict the treatment response in clinical practice, presumably due to frequently encountered artifacts. Currently, hypopharygneal multichannel intraluminal impedance-pH catheters incorporating two trans-upper esophageal sphincter impedance sensors enable to differentiate pharyngeal refluxes from swallows. The validation of pharyngeal acid reflux episodes that are relevant to anti-reflux treatment is, therefore, crucial. Given no diagnostic gold standard of LPR, this review article aimed to discuss the evolution of objective diagnostic testing and its predictive role of treatment response.

Abstract
Laryngopharyngeal reflux (LPR) is characterized by backflow of gastric or gastroduodenal content and gases into the upper aerodigestive tract, which can damage the mucus membranes of the larynx and pharynx. It is associated with a variety of symptoms such as retrosternal burning and acid regurgitation, or other unspecific symptoms such as hoarseness, globus sensation, chronic cough, or mucus hypersecretion. Due to the lack of data and the heterogeneity of studies, diagnosis of LPR is problematic and challenging, as recently discussed. Moreover, the different therapeutic approaches are also discussed controversially in the face of the poor evidence base, and include pharmacologic and conservative dietary measures. Hence, in the following review, the available options for treatment of LPR are critically discussed and summarized for daily clinical use.

Abstract
PURPOSE To evaluate the differences in diagnostic rates according to the age and sex of patients with suspected laryngopharyngeal reflux (LPR) symptoms and completed the 24-hour hypopharyngeal-esophageal multichannel intraluminal impedance-pH (24h-HEMII-pH) monitoring. METHODS Patients with LPR symptoms underwent the 24h-HEMII-pH monitoring. We compared the diagnostic rates of LPR in patients with LPR symptoms according to age and sex. The number of reflux episodes and type of reflux were compared among patients who were confirmed to have LPR according to age and sex. RESULTS A total of 249 patients with suspected LPR symptoms who completed 24h-HEMII-pH monitoring were analyzed. A total of 170 patients (68.3%) were diagnosed with LPR after 24h-HEMII-pH monitoring. There were 57 (67.1%) men and 113 (68.9%) women. The old age group (older than 55 years) showed a statistically significant higher diagnostic rate than the young age group (73.5%, 60.8%, p=0.034). Women's diagnostic rate was statistically higher in the old age group than that in the young age group (75% vs. 58.3%, p=0.026). There were no specific differences in the number of refluxes in the diagnosed patients between the age groups, and there were no differences in the initial reflux symptom index. CONCLUSIONS Among those who visited the clinic with suspected LPR symptoms and performed 24h-HEMII-pH monitoring, the diagnostic rate of LPR was higher in the older age group than that in the younger age group.

Abstract
Laryngopharyngeal reflux (LPR) is a common disorder in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). This meta-analysis was carried out to evaluate the LPR prevalence in individuals with OSAHS and to analyze the correlation of LPR positivity with the clinical features of patients with OSAHS. A detailed review of the English and Chinese literature on the occurrence of LPR in patients with OSAHS was performed by employing online search tools such as PubMed, EMBASE, Web of Science, VIP, CNKI, WanFang, etc. Two researchers analyzed the studies for quality according to the STROBE standard checklist. The acquired data were analyzed using Stata 11.0 and R 3.6.1 software. The effect size was estimated and calculated using weighted mean difference (WMD) and correlation coefficients. Moreover, a combined analysis was performed by employing either a random- or fixed-effects model. Ultimately, 27 studies met our inclusion criteria. Our study revealed that the LPR prevalence in OSAHS patients was 49%. We carried out subgroup analyses as per OSAHS severity, ethnicity, and body mass index (BMI). The results suggested that the probability of LPR in European and American patients with OSAHS was higher, and the prevalence of LPR was higher in obese individuals and patients with severe OSAHS. Moreover, apnea-hypopnea index (AHI) and BMI were higher in LPR-positive OSAHS patients than in LPR-negative OSAHS patients, but no significant variation in age was observed in the two groups. Moreover, the reflux symptom index (RSI) scores and the reflux finding score (RFS) exhibited a positive correlation with AHI. The current literature shows a higher incidence of LPR in individuals with OSAHS (49%). The severity of AHI in individuals with OSAHS is associated with the presence of LPR. Patients with OSAHS accompanied by LPR showed higher BMI and AHI as compared to those patients with LPR-negative OSAHS.

Abstract
PURPOSE Laryngopharyngeal reflux disease (LPRD) is a general term for the reflux of gastroduodenal contents into the laryngopharynx, oropharynx and even the nasopharynx, causing a series of symptoms and signs. Currently, little is known regarding the physiopathology of LPRD, and proton pump inhibitors (PPIs) are the drugs of choice for treatment. Although acid reflux plays a critical role in LPRD, PPIs fail to relieve symptoms in up to 40% of patients with LPRD. The influence of other reflux substances on LPRD, including pepsin, bile acid, and trypsin, has received increasing attention. Clarification of the substances involved in LPRD is the basis for LPRD treatment. METHODS A review of the effects of acids, pepsin, bile acids, and trypsin on laryngopharyngeal reflux diseases was conducted in PubMed. RESULTS Different reflux substances have different effects on LPRD, which will cause various symptoms, inflammatory diseases and neoplastic diseases of the laryngopharynx. For LPRD caused by different reflux substances, 24-h multichannel intraluminal impedance combined with pH-metry (MII-pH), salivary pepsin, bile acid and other tests should be established so that different drugs and treatment courses can be used to provide patients with more personalized treatment plans. CONCLUSION This article summarizes the research progress of different reflux substances on the pathogenesis, detection index and treatment of LPRD and lays a theoretical foundation to develop target drugs and clinical diagnosis and treatment.

Abstract
OBJECTIVES To review the normative data for acid, weakly acid, and nonacid proximal esophageal (PRE) and hypopharyngeal reflux (HRE) events in diagnosing laryngopharyngeal reflux (LPR) using ambulatory reflux monitoring. DATA SOURCES PubMed, Cochrane Library, and Scopus. REVIEW METHODS A literature search was conducted about the normative data for PRE and HRE on multichannel intraluminal impedance-pH monitoring (MII-pH), hypopharyngeal-esophageal MII-pH (HEMII-pH), or oropharyngeal pH monitoring using PICOTS (population, intervention, comparison, outcome, timing, and setting) and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statements. Outcomes reviewed included device characteristics, impedance/pH sensor placements, study duration, number/average and percentiles of PRE or HRE occurrence, and the event characteristics (pH, composition, and position). RESULTS Of 154 identified studies, 18 met criteria for analysis, including 720 healthy individuals. HEMII-pH, MII-pH, and oropharyngeal pH monitoring were used in 7, 6, and 5 studies, respectively. The definition and inclusion/exclusion criteria of healthy individuals varied substantially across studies, with 6 studies considering only digestive symptoms to exclude potential LPR patients. Substantial heterogeneity across studies was noted, including impedance/pH sensor placements/configurations and definitions of composition (liquid, gas, mixed) and type (acid, weakly acid, nonacid) of PRE/HRE. The 95th percentile thresholds were 10 to 73 events for PRE, 0 to 10 events for HRE on HEMII-pH, and 40 to 128 for events with pH <6.0 on oropharyngeal pH monitoring. Most HREs were nonacid and occurred upright. The mean HRE among healthy individuals was 1. CONCLUSION The low number of studies and the heterogeneity in inclusion criteria, definitions, and characterization of PRE and HRE limit the establishment of consensual normative criteria for LPR on ambulatory reflux monitoring. Future large multicenter studies are needed.

Impact of subspecialty training on management of laryngopharyngeal reflux: results of a worldwide survey. Eur Arch Otorhinolaryngol 2021; 278:1933-1943.

Abstract
OBJECTIVE To study the management of laryngopharyngeal reflux (LPR) among the subspecialties of practicing otolaryngology-head and neck surgeons and their trainees. METHODS A survey was sent to over 8000 otolaryngologists (OTOHNS) over 65 countries, utilizing membership lists of participating otolaryngological societies. The outcomes were answers to questions regarding LPR knowledge and practice patterns, and included queries about its definition, prevalence, clinical presentation, diagnosis, and treatment. RESULTS Of the 824 respondents, 658 practiced in one specific otolaryngologic subspecialty. The symptoms and findings thought to be the most related to LPR varied significantly between subspecialists. Extra-laryngeal findings were considered less by laryngologists while more experienced OTOHNS did not often consider digestive complaints. Compared with colleagues, otologists, rhinologists and laryngologists were less aware of the involvement of LPR in otological, rhinological and laryngological disorders, respectively. Irrespective of subspecialty, OTOHNS consider symptoms and signs and a positive response to empirical therapeutic trial to establish a LPR diagnosis. Awareness regarding the usefulness of impedance pH-studies is low in all groups. The therapeutic approach significantly varies between groups, although all were in agreement for the treatment duration. The management of non-responder patients demonstrated significant differences among laryngologists who performed additional examinations. The majority of participants (37.1%) admitted to being less than knowledgeable about LPR management. CONCLUSIONS LPR knowledge and management vary significantly across otolaryngology subspecialties. International guidelines on LPR management appear necessary to improve knowledge and management of LPR across all subspecialties of otolaryngology.

Abstract
Introduction Laryngopharyngeal reflux (LPR) is a prevalent condition in outpatients visiting the otorhinolaryngological clinic, with many controversies regarding its diagnosis and follow-up. Therefore, there is a need for clinical instruments that can diagnose individuals and monitor the results of their treatment. Objective To evaluate the applicability of the scores translated and adapted to Brazilian Portuguese: Reflux Symptom Index (RSI) and Endolaryngeal Reflux Findings Scale (ERFS), as instruments for post-treatment follow-up of LPR. Method A total of 35 individuals with atypical symptoms of gastroesophageal reflux disease and with an objective diagnosis of LPR, confirmed by high digestive endoscopy and 24-hour esophageal pH-metry dual probe test were submitted to the RSI and ERFS questionnaires, used in the pre- and post-treatment of 90 days with a Proton Pump Inhibitor. Result The evaluation of RSI and ERFS in the pre- and post-treatment showed a reduction in the results of the two scores, with a higher drop in the RSI ( p < 0.001) than in the ERFS ( p = 0.014). Although there was an improvement in the values in 23.9% of the individuals in the ERFS, there was no change in the category ( p = 0.057), different from the RSI ( p < 0.001), where there was a 67.4% improvement in values, as well as change in category (score went from positive to negative). There was a correlation between RSI and ERFS, moderate in the pretreatment and strong in the post-treatment. Conclusion The RSI and ERFS scores, when translated and adapted for Brazilian Portuguese and applied simultaneously, can be considered a good tool for post-treatment LPR follow-up.

Abstract
Laryngopharyngeal reflux (LPR) is a common disease in the general population with acute or chronic symptoms. LPR is often misdiagnosed in primary care because of the lack of typical gastroesophageal reflux disease (GERD) symptoms and findings on endoscopy. Depending on the physician's specialty and experience, LPR may be over- or under-diagnosed. Management of LPR is potentially entirely feasible in primary care as long as General Practitioners (GPs) are aware of certain "red flags" that will prompt referral to a Gastroenterologist or an Otolaryngologist. The use of patient-reported outcome questionnaires and the consideration of some easy ways to diagnose LPR without special instrumentation oropharyngeal findings may help the GP to diagnose and often manage LPR. In this review, we provide a practical algorithm for LPR management for GPs and other specialists that cannot perform fiberoptic examination. In this algorithm, physicians have to exclude some confounding conditions such as allergy or other causes of pharyngolaryngitis and "red flags". They may prescribe an empirical treatment based on diet and behavioral changes with or without medication, depending on the symptom severity. Proton pump inhibitors and alginates remain a popular choice in order to protect the upper aerodigestive tract mucosa from acid, weakly acid and alkaline pharyngeal reflux events.

Abstract
OBJECTIVES To investigate the role of gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) in the development of dental disorders. METHODS The first outcome was review of the role of reflux in the development of dental disorders in adults. The second outcome was review of the potential pathophysiological mechanisms underlying the association between reflux and dental disorders. Three investigators screened publications for eligibility and exclusion based on predetermined criteria through a literature search conducted on PubMed, Cochrane Library, and Scopus according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). RESULTS From 386 publications, 24 studies were kept for analysis. Objective approaches were used in 16 studies to confirm GERD diagnosis. Pharyngeal reflux episodes (LPR) were considered in 2 studies. No study considered nonacid reflux. The study results supported a higher prevalence of dental erosion and caries in reflux patients compared with healthy individuals. Patients with dental erosion have a higher prevalence of reflux than controls. The pathophysiological mechanisms would involve changes in the saliva physiology. No study investigated the microbiota modifications related to reflux although the findings are supporting the critical role of microbiota change in the development of dental disorders. There is an important heterogeneity between studies about diagnostic methods and clinical outcome evaluation. CONCLUSION The involvement of reflux in the development of dental disorders is not formally demonstrated and requires future investigations considering pharyngeal acid and nonacid reflux episodes and in particular their potential impact on oral microbiota.

Abstract
OBJECTIVES/HYPOTHESIS To assess the evolution of laryngeal and extralaryngeal symptoms and findings of laryngopharyngeal reflux (LPR) throughout a 3-month to 9-month treatment. STUDY DESIGN Prospective Controlled Study. METHODS One hundred twenty-seven LPR patients and 123 healthy individuals were enrolled from four European hospitals. Patients were managed with a 3-month personalized treatment considering the LPR characteristics at the impedance-pH monitoring. Regarding the clinical therapeutic response, treatment was adapted for 3 to 6 additional months. Symptoms and findings were assessed throughout the therapeutic course with the Reflux Symptom Score (RSS) and the short version of the Reflux Sign Assessment (sRSA). The relationship between patient and reflux characteristics, symptoms, and findings was assessed. RESULTS One hundred twenty-one LPR patients completed the study. LPR patients exhibited more laryngeal and extralaryngeal symptoms and findings than healthy individuals. RSS significantly improved from baseline to 6 weeks posttreatment and continued to improve from 3 months to 6 months posttreatment. sRSA significantly improved from baseline to 3 months posttreatment. No further improvement was noted at 6 months posttreatment for pharyngeal and oral findings. Laryngeal findings continued to improve from 3 months to 6 months posttreatment. There was a significant association between patient stress level and RSS (P = .045). At 3 months posttreatment, 28.1% of patients had high or complete response, whereas 47.1% required 6 months or 9 months of treatment. Overall, 24.8% of patients had an LPR chronic course. CONCLUSIONS Laryngeal and extralaryngeal symptoms and findings significantly improved throughout treatment in LPR patients. The improvement of laryngeal findings was slower. Regarding the low prevalence of some digestive or otolaryngological symptoms, a short version of the RSS could be developed. LEVEL OF EVIDENCE 3 Laryngoscope, 131:1332-1342, 2021.

Abstract
Objective:To investigate the clinical effect of proton pump inhibitor combined with ranitidine on patients with laryngopharyngeal reflux. Method:Seventy patients with laryngopharyngeal reflux diagnosed in our hospital were randomly divided into group A and group B according to admission time. The difference of B symptom index, reflux symptom scale, sleep breathing test, quality of life and well-being score between the two groups were detected. Result:Before treatment, the RSI index, RFS similarity and QOLS and MUNSH scores were similar (P>0.05). After four weeks of treatment, the group B score was 3.3±1.2, the group A score was 8.2±3.5, and the group B score was significantly lower. The RFS score of group A (6.2±2.3) was higher than that of group B (2.1±1.9, P<0.05). The scores of QOLS and MUNSH in group B were (67.57±7.26) and (23.99±3.44), respectively. The scores of QOLS and MUNSH in group A (50.13±10.19) and (12.21±1.47), respectively. The results of the two groups were significantly different (P<0.05). After treatment, the RSI index, RFS score, QOLS and MUNSH scores of the two groups were lower than those before treatment. (P<0.05). As for the sleep respiration monitoring (PSG) results, after 4-week treatment, compared with the group A, the total sleep time of the group B was significantly increased (P<0.05), and the number of wakefulness and wakefulness was significantly decreased. The duration of Ⅲ+Ⅳ sleep was also significantly increased, and the proportion of REM sleep time and AHI was significantly reduced (P<0.05). Conclusion:Proton pump inhibitor combined with ranitidine is more effective and safer than single drug treatment, and can significantly improve the throat reflux symptoms.

Int Arch Otorhinolaryngol 2020; 25:e273-e278. [PMID: 33968232 PMCID: PMC8096499 DOI: 10.1055/s-0040-1709987] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2019] [Accepted: 03/04/2020] [Indexed: 12/22/2022] Open
Abstract
Introduction
Twenty-four-hour multichannel intraluminal impedance with double probe pH monitoring (MII-pH), though considered the most sensitive tool for the diagnosis of gastroesophageal reflux disease (GERD), is invasive, time consuming, not widely available, and unable to detect non-acid reflux. In contrast, the presence of pepsin in the saliva would act as a marker for reflux, considering that pepsin is only produced in the stomach.
Objective
To evaluate the predictive value of salivary pepsin in diagnosing laryngopharyngeal reflux (LPR) as suggested by the results of reflux symptom index (RSI > 13), reflux finding score (RFS > 7), and positive response to treatment with a 4-week course of proton-pump inhibitors.
Methods
This prospective study was done at a tertiary care hospital on 120 adult patients attending ENT OPD with clinical diagnosis of LPR. The presence of pepsin in their pharyngeal secretions and saliva using a lateral flow device, the Peptest, was compared with RSI, RFS, and with the response to medical treatment using the Chi-squared test.
Results
Salivary pepsin was found to be positive in 68% of the patients, with 87.5% of them showing positive response to treatment. Chi-squared analysis showed a significant association between positive salivary pepsin and RFS > 7, RSI >13, a combination of RFS > 7 and RSI > 13 as well as with response to treatment (
p
< 0.0001).
Conclusion
When considered along with the clinical indicators of RFS and RSI of more than 7 and 13, respectively, and/or with a response to treatment, a positive salivary pepsin test indicates statistically significant chance of presence of LPR.

Abstract
Objectives To investigate the existing published evidence supporting the role of laryngopharyngeal reflux (LPR) in the development of the select nonfunctional laryngeal diseases of laryngotracheal stenosis, granuloma, leukoplakia, and laryngeal infections Data Sources PubMed, Cochrane Library, and Scopus. Review Methods A systematic review was performed by 3 independent investigators for studies providing information about the prevalence and role of LPR in the development of laryngotracheal stenosis, granuloma, leukoplakia, and laryngeal infections. Diagnostic criteria and clinical outcome evaluation of included studies were analyzed with PRISMA criteria. Results Of the 64 relevant publications, 27 clinical and 4 basic science studies were included. Ten studies used objective reliable examinations for LPR diagnosis (eg, dual- or triple-probe or oropharyngeal pH monitoring, multichannel intraluminal impedance–pH monitoring, or pepsin detection). According to the bias analysis and the results of studies, the association between LPR and laryngotracheal stenosis, leukoplakia, laryngeal papillomatosis, or vocal fold granuloma remains poorly demonstrated. There is a notable heterogeneity among included studies regarding their inclusion criteria, diagnostic methods, and clinical outcome evaluation. Although some experimental findings support the involvement of bile salts and other gastroduodenal proteins active in alkaline pH, no included clinical studies assessed the role of nonacid and mixed reflux through multichannel intraluminal impedance–pH monitoring. Conclusion The involvement of LPR in the development of leukoplakia, laryngotracheal stenosis, vocal fold granuloma, and laryngeal papillomatosis is currently not demonstrated. The potential relationship between LPR and these select nonfunctional laryngeal diseases must be confirmed through future clinical and experimental studies considering acid, nonacid, and mixed LPR.

Abstract
Airway reflux is implicated in the pathophysiology of a wide range of adult and pediatric upper and lower airway diseases. However, the diagnosis of proximal reflux-associated disease remains challenging due to evolving clinical criteria and institutional and regional variances in diagnostic practices. Evidence suggests that nonacidic contents of reflux may serve as both pathologic mediators of and biomarkers for reflux in the upper airway. Furthermore, they offer potential pharmaceutical and surgical intervention targets and are the focus of novel clinical diagnostic tools currently under investigation.

Abstract
OBJECTIVE To analyze the role of nonacid reflux in laryngopharyngeal reflux diseases (LPRD). METHODS From January 2014 to April 2019, 344 patients associated with LPRD underwent 24-h multichannel intraluminal impedance-pH monitoring, and their reflux symptom index (RSI) and reflux finding score (RFS) were recorded. The numbers of acid, weakly acidic and alkaline reflux events in the laryngopharynx were counted, and the consistency analysis of the results with the results of the RSI and RFS was conducted. RESULTS Among the 344 patients, nonacid reflux events accounted for 74.1% (1367/1845) of the all reflux events. There were 111 patients with ≥ 3 acid reflux events, 218 patients with ≥ 3 any kinds of reflux events, and 257 patients with positive results of RSI or RFS. Taking the results of the RSI and or RFS as a reference, the sensitivity, specificity and consistency test Kappa value for the diagnosis of LPRD according to the existence of ≥ 3 acid reflux events were 41.2%, 94.2% and 0.228, respectively. With the existence of three or more all kinds of reflux events as the standard, the sensitivity, specificity and consistency test Kappa value were 76.7%, 74.7% and 0.449, respectively. CONCLUSION The nonacid reflux events account for the highest proportion of laryngopharyngeal reflux events, and the consistency of the results of RSI and or RFS with all reflux events is higher than that with only acid reflux events, that indicates nonacid reflux may play an important role in LPRD.

[PMID: 32097534 DOI: 10.1111/coa.13518] [Citation(s) in RCA: 26] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2019] [Revised: 12/25/2019] [Accepted: 01/15/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND Diagnosis and treatment of presumed laryngopharyngeal reflux (LPR) remain controversial. Empiric medication trials remain widespread for suspected LPR despite emerging evidence against proton pump inhibitor (PPI) safety and for pepsin as a mediator of LPR symptoms. Ongoing concerns exist related to inaccurate diagnosis, the cost and morbidity of potentially unnecessary PPI prescriptions, and availability and interpretation of objective reflux testing. OBJECTIVES To review contemporary evidence that does and does not support empiric medication trials for presumed LPR. METHODS PubMed, Scopus and Cochrane Library were searched for literature about benefits, limitations and alternatives to empiric medication trial for LPR, in order to present both sides of this debate and identify best practices. RESULTS The majority of physicians perform prolonged empiric medication trial with PPIs for patients with suspected LPR. Because symptoms and signs of LPR are non-specific, empiric medication trials require exclusion of other conditions that can mimic LPR. Following a PPI empiric medication trial, over one-third of patients remain non-responders. The use of hypopharyngeal-oesophageal multichannel intraluminal impedance-pH monitoring (HEMII-pH) has benefits and limitations in objective diagnosis of LPR. CONCLUSIONS Use of PPIs for single-agent empiric medication trial does not account for possible non-responders with non-acid or mixed LPR. If LPR diagnosis remains uncertain, alginates can be added to PPI trials. HEMII-pH testing upfront is ideal for patients with suspected LPR, but not always practical; it is indicated when PPI and alginate empiric medication trials have failed or when comorbidities confuse the diagnosis. A more comprehensive, combination therapy empiric medication trial regimen may be needed.

Do Laryngologists and General Otolaryngologists Manage Laryngopharyngeal Reflux Differently? Laryngoscope 2020; 130:E539-E547. [PMID: 31913520 DOI: 10.1002/lary.28484] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2019] [Revised: 11/20/2019] [Accepted: 12/06/2019] [Indexed: 02/06/2023]
Abstract
OBJECTIVE To investigate current practices of laryngologists and non-laryngologists in management of Laryngopharyngeal Reflux (LPR). METHODS An online survey was sent to members of otolaryngology societies about LPR, and subgroup analysis was performed between laryngologists and non-laryngologists. This survey was conducted by the LPR Study Group of Young Otolaryngologists of the International Federation of Otolaryngological Societies. RESULTS A total of 535 otolaryngologists completed the survey. Among them, 127 were laryngologists and 408 were non-laryngologists. Collectively, symptoms most commonly attributed to LPR are cough after lying down/meal, throat clearing, and acid brash; most common findings are thought to be arytenoid erythema and posterior commissure hypertrophy. Respectively, 12.5% and 5% of non-laryngologists and laryngologists believe that ≥50% of LPR patients suffer from heartburn (P = .010). Non-laryngologists are more aware about some extra-laryngeal findings associated with LPR (eg, pharyngeal erythema) than laryngologists. Neither laryngologists nor non-laryngologists associated development of benign lesions of the vocal folds with reflux. The management of LPR substantially differs between groups, with laryngologists indicating increased awareness of (impedance)-pH monitoring as well as the prevalence and treatment of nonacid/mixed LPR. Conversely, non-laryngologists are much more likely to include gastroenterology referral in their management of presumed LPR. Respectively, 44.8% and 27.6% of non-laryngologists and laryngologists believe themselves not sufficiently knowledgeable about LPR. CONCLUSIONS Significant differences exist between laryngologists and non-laryngologists in diagnosis and treatment of LPR. Overall only one-third of responders believe themselves to be sufficiently educated about LPR. LEVEL OF EVIDENCE 4 Laryngoscope, 130:E539-E547, 2020.

Abstract
OBJECTIVE To investigate the clinical features and the therapeutic response of laryngopharyngeal reflux (LPR) patients with or without gastroesophageal reflux disease (GERD). METHODS Patients with LPR symptoms were enrolled from three European Hospitals. The diagnosis of LPR and GERD was made through impedance-pH monitoring (MII-pH). A gastrointestinal endoscopy was realized in patients with digestive complaints or ≥60 years old. The 3- to 6-month treatment was based on the association of diet, pantoprazole, alginate, and magaldrate regarding the MII-pH characteristics. Reflux Symptom Score (RSS) and Reflux Sign Assessment (RSA) were used to evaluate the clinical evolution throughout treatment. The gastrointestinal endoscopy findings, clinical features, and therapeutic response were compared between patients with LPR and GERD (LPR/GERD) and patients with LPR. RESULTS One hundred and eleven LPR patients were included, 54 being LPR/GERD. LPR/GERD patients had a higher number of proximal reflux episodes compared with LPR patients. The prevalence of esophagitis, hernia hiatal, and lower esophageal sphincter insufficiency did not differ between groups. The presence of GERD was strongly associated with acid LPR. Patients without GERD had a higher proportion of nonacid and mixed LPR compared with LPR/GERD patients. The pre- to posttreatment evolutions of RSS and RSA were quite similar in both groups, with the exception of the 3- to 6-month improvement of digestive symptoms, which was better in LPR/GERD group. The therapeutic success rates were 79.6% and 77.2% in GERD/LPR and LPR group, respectively. CONCLUSION GERD is predictive of acid LPR. The clinical evolution and the therapeutic response rates were quite similar in both groups. LEVEL OF EVIDENCE 4 Laryngoscope, 130: E479-E489, 2020.

Abstract
BACKGROUNG For a long time, laryngopharyngeal reflux disease (LPRD) has been treated by proton pump inhibitors (PPIs) with an uncertain success rate.
AIM To shed light the current therapeutic strategies used for LPRD in order to analysis the rationale in the LPRD treatment.
METHODS Three authors conducted a PubMed search to identify papers published between January 1990 and February 2019 about the treatment of LPRD. Clinical prospective or retrospective studies had to explore the impact of medical treatment(s) on the clinical presentation of suspected or confirmed LPRD. The criteria for considering studies for the review were based on the population, intervention, comparison, and outcome framework.
RESULTS The search identified 1355 relevant papers, of which 76 studies met the inclusion criteria, accounting for 6457 patients. A total of 64 studies consisted of empirical therapeutic trials and 12 were studies where authors formally identified LPRD with pH-monitoring or multichannel intraluminal impedance-pH monitoring (MII-pH). The main therapeutic scheme consisted of once or twice daily PPIs for a duration ranged from 4 to 24 wk. The most used PPIs were omeprazole, esomeprazole, rabeprazole, lansoprazole and pantoprazole with a success rate ranging from 18% to 87%. Other composite treatments have been prescribed including PPIs, alginate, prokinetics, and H2 Receptor antagonists.
CONCLUSION Regarding the development of MII-pH and the identification of LPRD subtypes (acid, nonacid, mixed), future studies are needed to improve the LPRD treatment considering all subtypes of reflux.

Abstract
BACKGROUND Laryngopharyngeal reflux (LPR) is suspected when the symptoms are attributed to the penetration of acidic gastroesophageal reflux (GER) into the larynx. However, the relationships between the intensity of LPR and symptoms and laryngeal injury have not been elucidated. Several factors confound the study of LPR, namely pH is monitored in the pharynx (pharyngeal reflux) but the pharyngeal acidity (pH) required to induce laryngeal injury is unknown, the GER origin of pharyngeal acid is not always established, and a recent treatment with proton pump inhibitors (PPI) confounds the analysis. AIMS We aimed to limit these confounding factors to analyze the relationship between LPR and symptoms and laryngeal injury. METHODS We used dual pharyngeal and distal esophageal 24-h pH/impedance monitoring to establish GER origin of pharyngeal reflux, we used an unbiased approach to analysis by evaluating a whole range of acidity (pH < 6, pH < 5.5, pH < 5.0, pH < 4.5 and pH < 4.0) in patients with suspected LPR without PPI for > 30 days. RESULTS Pharyngeal reflux was (median[IQR]) 14[8-20.5] and 4[1.5-6.5] pharyngeal reflux episodes with pH < 6.0 and pH < 5.5, respectively. Pharyngeal reflux with pH < 5.0 was rare. Comprehensive analysis did not reveal any correlation between symptoms (reflux symptom index) or laryngeal injury (reflux finding score) and the number of pharyngeal reflux episodes or duration of pharyngeal acid exposure at any pH level. CONCLUSION Unbiased comprehensive approach did not reveal any relationship between acidic pharyngeal reflux and the symptoms or laryngeal injury attributed to LPR. Limited clinical usefulness of pharyngeal monitoring reported by others is unlikely due to confounding factors.

Abstract
OBJECTIVE To review the current literature about the epidemiology, clinical presentation, diagnosis, and treatment of laryngopharyngeal reflux (LPR). DATA SOURCES PubMed, Cochrane Library, and Scopus. METHODS A comprehensive review of the literature on LPR epidemiology, clinical presentation, diagnosis, and treatment was conducted. Using the PRISMA statement, 3 authors selected relevant publications to provide a critical analysis of the literature. CONCLUSIONS The important heterogeneity across studies in LPR diagnosis continues to make it difficult to summarize a single body of thought. Controversies persist concerning epidemiology, clinical presentation, diagnosis, and treatment. No recent epidemiologic study exists regarding prevalence and incidence with the use of objective diagnostic tools. There is no survey that evaluates the prevalence of symptoms and signs on a large number of patients with confirmed LPR. Regarding diagnosis, an increasing number of authors used multichannel intraluminal impedance-pH monitoring, although there is no consensus regarding standardization of the diagnostic criteria. The efficiency of proton pump inhibitor (PPI) therapy remains poorly demonstrated and misevaluated by incomplete clinical tools that do not take into consideration many symptoms and extralaryngeal findings. Despite the recent advances in knowledge about nonacid LPR, treatment protocols based on PPIs do not seem to have evolved. IMPLICATIONS FOR PRACTICE The development of multichannel intraluminal impedance-pH monitoring and pepsin and bile salt detection should be considered for the establishment of a multiparameter diagnostic approach. LPR treatment should evolve to a more personalized regimen, including diet, PPIs, alginate, and magaldrate according to individual patient characteristics. Multicenter international studies with a standardized protocol could improve scientific knowledge about LPR.
