RESUMEN

OBJECTIVE: To investigate the consistency between the reflux symptom score (RSS) and the multitemporal salivary pepsin test in screening for laryngopharyngeal reflux (LPR) and the screening value of the RSS for LPR by simultaneously administering daytime multitemporal salivary pepsin test and RSS to patients. METHODS: This was a single-center prospective observational study. All included patients underwent simultaneous daytime multitemporal salivary pepsin testing and RSS. A participant was considered to have LPR when one or more positive salivary pepsin test results or RSS score > 13 were obtained. The consistency between the multitemporal salivary pepsin test and the RSS was compared by the weighted Cohen's kappa statistic. The screening value of the RSS for LPR was investigated by receiver operating characteristic (ROC) analysis. RESULTS: A total of 67 patients were included. The positivity rate of LPR was 71.64% according to the results of the multitemporal salivary pepsin test. According to RSS, the positive rate of LPR was 70.15%. The weighted Kappa value between the multitemporal salivary pepsin test and the RSS was 0.675 (p < 0.001). The area under curve of RSS screening for LPR was 0.843 (p < 0.01), and the sensitivity, specificity, positive predictive value, and negative predictive value of RSS screening for LPR were 89.58%, 78.95%, 91.49%, and 75%, respectively. CONCLUSION: There is a good consistency between the RSS and the multitemporal salivary pepsin test, and the RSS has a good screening value for LPR, which can be applied to screen for LPR in otolaryngologic patients.

RESUMEN

BACKGROUND: Issues associated with proton pump inhibitor (PPI) usage have been documented. PPIs affect the gastrointestinal microbiome, as well as the saliva microbiota of healthy individuals. However, the alterations in the saliva microbiota of laryngopharyngeal reflux (LPR) patients remain unclear. This study aims to examine the composition of saliva microbiota in LPR patients before and after PPI usage through a self-controlled study. METHODS: Thirty-two adult LPR patients participated in the study. Saliva samples were collected before and after an 8-week regimen of twice-daily administration of 20-mg esomeprazole. The impact of PPI administration on bacterial communities was assessed using 16 S rRNA gene sequencing. The functional and metabolic changes in saliva microbial communities after PPI usage were analyzed using PICRUSt2 based on our 16 S rRNA gene sequencing results. RESULTS: The alpha diversity within the salivary microbiota, as measured by the PD-whole-tree index, exhibited a significant difference between samples collected before and after PPI application (P = 0.038). Additionally, PCoA analysis of unweighted UniFrac distances (beta diversity) revealed distinct separation of saliva sample microbiota structures before and after PPI application in LPR patients, with statistical significance (Adonis test, R2 = 0.063, P< 0.010). Taxon-based analysis indicated that PPI administration increased the abundance of Epsilonproteobacteria, Campylobacterales, Campylobacteraceae, Campylobacter, and Campylobacter_gracilis, while reducing the abundance of Lactobacillaceae and Lactobacillus in salivary samples ( P< 0.050). Using LEfSe to compare bacterial abundances, Bacillaceae and Anoxybacillus were found to be enriched before PPI usage in LPR patients. Furthermore, the proportion of genes responsible for indole alkaloid biosynthesis in the salivary microbiota of LPR patients significantly increased after PPI therapy (P< 0.050). CONCLUSIONS: These findings indicate that PPIs induce alterations in the salivary microbiota of LPR patients. CHINESE CLINICAL TRIAL REGISTRY: No. ChiCTR2300067507.

RESUMEN

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 .

RESUMEN

BACKGROUND: Laryngeal involvement is rare in tuberculosis, representing around 1% of all cases of this infection worldwide. Given the larynx' location in the airway, this form of tuberculosis is of particular importance because it is highly contagious. With our hospital being in a high tuberculosis burden area, we propose to characterize the clinical presentation, evolution, and laryngoscopy findings of a series of laryngeal tuberculosis cases in order to reduce misdiagnosis. METHODS: Epidemiological and clinical data from 10 patients diagnosed with laryngeal tuberculosis in the Otorhinolaryngology department of (Blinded for manuscript) between January 2011 and December 2021 were retrieved and analyzed. RESULTS: There were eight males and two females. Seven patients had a history of smoking and alcohol abuse and four had silicosis. Hoarseness was the most reported symptom (n = 9). The most frequent site of involvement were the true vocal cords (n = 6). All patients but one had concomitant active pulmonary tuberculosis. Patients had full resolution of laryngeal symptoms between 4 and 16 weeks after initiating antituberculosis treatment. CONCLUSION: Laryngeal tuberculosis is indeed a great deceiver. On one hand it can look like a simple polypoid lesion or simulate laryngopharyngeal reflux; but on the other hand its risk factors, symptoms and appearance simulate laryngeal carcinoma like no other. Since most patients present with concomitant pulmonary tuberculosis, all suspect laryngeal lesions should perform a chest radiograph prior to rigid laryngoscopy. Antituberculosis treatment is effective in both alleviating symptoms and reducing the risk of transmission.

RESUMEN

OBJECTIVE: To assess whether adding metoclopramide to a protocol of maropitant and pantoprazole would reduce incidence of ptyalism, vomiting and regurgitation in brachycephalic dogs undergoing thoracolumbar spinal surgery. STUDY DESIGN: Randomized blinded controlled trial. ANIMALS: A total of 43 brachycephalic dogs undergoing thoracolumbar spinal surgery. METHODS: In addition to a standardized anaesthetic regimen, dogs were randomized to be administered either a 2 mg kg-1 day-1 metoclopramide constant rate infusion (CRI) or a saline solution at an equivalent infusion rate, started after anaesthetic induction and discontinued 5 hours after tracheal extubation. The presence of vomiting, regurgitation and pytalism, and short form of the Glasgow Composite Pain Scale pain scores were assessed by a blinded observer hourly for 4 hours, starting 1 hour postextubation. RESULTS: Regurgitation occurred in six dogs postoperatively; three dogs were in the placebo group and three in the metoclopramide group. The odds ratio (OR) of regurgitation after surgery did not differ between groups [OR: 0.76, 95% confidence interval (CI): 0.13-4.3, p = 0.76]. The odds of observing ptyalism at 3 and 4 hours was approximately 15 times less than 1 hour postoperatively (both OR: 15.4, 95% CI: 1.8-130.7, p = 0.012) and did not differ based on the addition of metoclopramide (OR: 0.73, 95% CI: 0.07-8.0, p = 0.79). The odds of observing pain did not change over time and did not differ based on the addition of metoclopramide (OR: 0.71, 95% CI: 0.12-4.2, p = 0.71). Vomiting did not occur during the study (0.0%, 95% CI: 0.0-8.2%). No adverse effects were observed during the study period in either group. CONCLUSIONS AND CLINICAL RELEVANCE: The addition of a metoclopramide CRI to maropitant and pantoprazole did not result in a significant reduction in ptyalism or regurgitation in brachycephalic dogs undergoing thoracolumbar spinal surgery.

RESUMEN

The pathophysiology of laryngopharyngeal reflux (LPR) and its impact on the vocal fold is not well understood, but may involve acid damage to vocal fold barrier functions. Two different components encompass vocal fold barrier function: the mucus barrier and tight junctions. Mucus retained on epithelial microprojections protects the inside of the vocal fold by neutralizing acidic damage. Tight junctions control permeability between cells. Here we developed an in vitro experimental system to evaluate acidic injury and repair of vocal fold barrier functions. We first established an in vitro model of rat vocal fold epithelium that could survive at least one week after barrier function maturation. The model enabled repeated evaluation of the course of vocal fold repair processes. Then, an injury experiment was conducted in which vocal fold cells were exposed to a 5-min treatment with acidic pepsin that injured tight junctions and cell surface microprojections. Both of them healed within one day of injury. Comparing vocal fold cells treated with acid alone with cells treated with acidic pepsin showed that acidic pepsin had a stronger effect on intercellular permeability than acid alone, whereas pepsin had little effect on microprojections. This result suggests that the proteolytic action of pepsin has a larger effect on protein-based tight junctions than on phospholipids in microprojections. This experimental system could contribute to a better understanding of vocal fold repair processes after chemical or physical injuries, as well as voice problems due to LPR pathogenesis.

RESUMEN

OBJECTIVE: To investigate the minimum therapeutic duration for patients with primary laryngopharyngeal reflux disease (LPRD) through the evaluation of symptom changes at multiple time points. STUDY DESIGN: Prospective uncontrolled. SETTING: University medical center. METHODS: Patients with LPRD at the 24-hour hypopharyngeal-esophageal multichannel intraluminal impedance-pH monitoring were recruited from the European Reflux Clinic. Depending on the type of LPRD, patients were treated with a combination of proton-pump inhibitors, alginate, or magaldrate. Symptoms were evaluated with the reflux symptom score (RSS) at baseline and throughout treatment (1-, 3-, 6-, and 9-month posttreatment). The most appropriate therapeutic duration was determined using the RSS changes. Signs were evaluated with the reflux sign assessment. RESULTS: A total of 159 patients completed the study. The mean age was 49.9 ± 15.7 years. At 1-month posttreatment, 97 patients (61.0%) were considered as early responders to treatment, and the treatment was stopped for 52 patients (32.7%). Of the 62 early nonresponders, 34 patients (21.4%) reached responded to treatment after 3 to 9 months. The cumulative therapeutic success rate at 1-month posttreatment (61.0%) progressively increased to reach a range of 82.4% to 99.3% at 9-month posttreatment. The RSS mainly decreased in the first month of treatment in early responders. In early nonresponders, RSS progressively decreased throughout the 9-month treatment period. The baseline severity of RSS is a strong predictor of therapeutic response. CONCLUSION: A therapeutic regimen of 1 month can be sufficient to treat one third of LPRD patients. The early nonresponders may require 3 to 9 months of treatment.

RESUMEN

PURPOSE: To examine the patient experience of laryngopharyngeal reflux diagnosis and factors that contributed to perceived difficulty with the process. MATERIALS AND METHODS: A 32-question anonymous survey was administered to individuals over 18 years old who reported a diagnosis of laryngopharyngeal reflux. The survey contained questions regarding demographics and individuals' experiences during the diagnostic workup along with the generic short patient experiences questionnaire. Percentages were calculated for all variables. Kendall rank correlation coefficient was performed to measure the strength and direction of association between laryngopharyngeal reflux workup and perceived difficulty with diagnosis. RESULTS: Of the 232 respondents, 59.9 % reported difficulty with the diagnostic process. Strong positive correlations were found between perceived difficulty with laryngopharyngeal reflux diagnosis and the following factors: total number of physicians seen (τb = 0.483, p < 0.001), time from symptom onset (τb = 0.300, p < 0.001), and time from first physician visit (τb = 0.479, p < 0.001). Results from the generic short patient experiences questionnaire showed moderate negative correlations between perceived difficulty with diagnosis and the following factors: perceived competence of physician (τb = -0.228, p < 0.001), perception that the physician cared for the patient (τb = -0.253, p < 0.001), perceived interest the physician had in the patient (τb = -0.259, p < 0.001), and time interacting with the physician (τb = -0.226, p < 0.001). CONCLUSIONS: Respondents report difficulty being diagnosed with laryngopharyngeal reflux. This correlates with increased time to receive a diagnosis, increased number of physicians seen, and factors related to the patient-physician relationship. Physicians can improve patient experience by focusing on clear communication with interactive patient appointments, and scheduling high yield diagnostic tests.

RESUMEN

BACKGROUND: Patients with chronic laryngopharyngeal symptoms, with or without pathologic reflux, frequently have poor response to standard therapies, which may be a result of overlapping cognitive-affective processes. Therefore, the aims of this study included measuring psychosocial distress and laryngeal-specific cognitive distress in patients with chronic laryngopharyngeal symptoms (LPS) as well as comparing these among laryngeal symptomatic patients with and without conclusive gastroesophageal reflux disease (GERD). METHODS: This prospective, single-center study enrolled adults with chronic LPS from 9/22 to 6/23. Patients completed eight questionnaires on quality of life, symptom burden, and psychosocial distress. The laryngeal cognitive affective tool (LCAT) assessed laryngeal-specific hypervigilance and anxiety; LCAT scores ≥33 were elevated. All patients underwent objective testing with endoscopy and/or ambulatory reflux monitoring and were categorized as proven GERD (GER+) or no proven GERD (GER-). KEY RESULTS: One hundred twenty-nine patients were included: 66% female, mean age 54.1 (17.5) years, mean BMI 27.6 (6.8) kg/m2, 66% Caucasian, 57% with an elevated LCAT, and 53% GER+. Moderate-to-severe anxiety was found in 39% and moderate-to-severe depression in 19%. An elevated LCAT alone or with an elevated anxiety/depression score was found in 58%. Patient-reported outcomes scores, including LCAT scores (32.9 (13.8) GER- vs. 33.1 (12.6) GER+, p = 0.91), were similar between patients with and without GER+. CONCLUSIONS AND INFERENCES: Patients with chronic LPS experience heightened levels of hypervigilance, symptom-specific anxiety, and psychosocial distress, regardless of the presence of pathologic GER.

RESUMEN

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.

RESUMEN

OBJECTIVE: To evaluate the efficacy of distal esophageal mean nocturnal baseline impedance (MNBI), a general marker of esophageal mucosal barrier integrity, in predicting laryngopharyngeal reflux (LPR) and symptomatic response to acid reflux therapy. METHODS: This retrospective study analyzed 173 patients who presented with symptoms of laryngopharyngeal reflux and underwent 24-h multichannel intraluminal impedance-pH (MII-pH) testing. Mean nocturnal baseline impedance values were calculated and assessed for their association and ability to predict LPR symptoms, MII-pH results, treatment response, and other markers of LPR. RESULTS: Notably, 153 of the 173 patients were tested off acid suppression medication and included in statistical analysis. Based on the MII-pH probe data, 108 (71%) patients had LPR, 8 (5%) had gastroesophageal reflux disease (GERD), and 37 (24%) were without pathologic reflux. Distal esophageal MNBI of LPR patients was significantly lower in LPR patients than patients with negative studies (1332 ± 94.8 vs. 2158 ± 173.5, p = 0.001). Among 118 patients who trialed antireflux therapy, a distal esophageal MNBI cutoff value of <1580 Ω was an independent predictor of treatment response (OR = 4.148 [1.877-9.189]). This value better predicted improvement with antireflux therapy for LPR than other objective MII-pH probe data, which were not independent predictors of treatment response. CONCLUSION: Distal esophageal MNBI values may have value in the diagnosis of LPR and potentially predict medication responsiveness in LPR patients.

RESUMEN

Rumination syndrome (RS) is an underdiagnosed behavioral disorder of recurrent regurgitation. Regurgitation occurs in RS due to increased gastric pressure achieved by subconscious contraction of the abdominal musculature wall, reversing the pressure gradient between the esophagus and the stomach. RS is mainly diagnosed clinically by the Rome Criteria with symptoms of regurgitation without retching of recently ingested food into the mouth and subsequent spitting or re-mastication. When the diagnosis is unable to be made clinically, supportive testing including fed impedance manometry can be considered. RS occurs worldwide, affecting patients of all ages, races, and genders with a prevalence of 3.1-5.8%. There is significant overlap with RS and disorders of a gut-brain interaction and upright gastroesophageal reflux driven by aerophagia and supragastric belching. There is also an association with mood disorder, fibromyalgia, and eating disorders. RS may be misdiagnosed as a variety of other syndromes including gastroesophageal reflux disease, gastroparesis, achalasia, and bulimia nervosa. Once RS is diagnosed, the mainstay of treatment is diaphragmatic breathing to lower the intragastric pressure and increase the lower esophageal pressure. Diaphragmatic breathing can be supported with biofeedback and cognitive behavioral therapy as well as medication options for more refractory cases. Response to therapy overtime and changes in symptoms overtime can now be tracked with a validated questionnaire.

RESUMEN

PURPOSE OF REVIEW: Symptoms/complications related to extraesophageal reflux (EER) are increasingly prevalent presentations and pose significant challenges for clinicians. We summarize and discuss clinical advances and developments in pathophysiology, testing and treatment algorithms of upper/lower airway manifestations of EER. RECENT FINDINGS: Growing evidence supports likely multifactorial causes of laryngeal symptoms, including EER, oropharyngeal pathologies, allergic conditions, and cognitive-affective processes (brain-larynx interaction). Diagnostic paradigm for laryngopharyngeal reflux (LPR) is shifting towards a personalized approach with noninvasive strategies/prediction tools to risk-stratify patients for upfront reflux testing over empiric acid suppression trials. Management should be multipronged to include antireflux therapies and treatments targeting other causes. Lower airway complications of EER may result in lung dysfunction and poor transplant outcomes. Esophageal symptoms are often absent and routine esophageal/reflux testing to guide timely antireflux therapies may lead to improved outcomes. Modalities that leverage impedance technology may be important, given the potential role of nonacidic reflux. Novel impedance-based metrics such as mean nocturnal baseline impedance and postreflux swallow-induced peristaltic wave index may provide adjunctive diagnostic values. SUMMARY: Standardized approach to diagnosis/management of EER should include multidisciplinary care teams and consider different phenotypes, nonreflux contributors, and the complex gut-airway relationships. Prompt antireflux therapies after careful candidate selection may improve outcomes of these airway complications.

RESUMEN

Postnasal drip (PND) is a common symptom encountered when evaluating subjects with sinonasal disease; it may be present without sinonasal disease or as a symptom of laryngopharyngeal reflux. It is postulated that PND stems from dysfunction of normal mucus clearance mechanisms; however, there is no definitive evidence elucidating an exact pathophysiology. Compounding the uncertainties surrounding PND is the lack of an objective assessment tool. Instead, treating physicians must rely on subjective complaints and investigators utilize validated patient-reported outcome instruments, such as the Sino-Nasal Outcome Test, to determine treatment efficacy. This review seeks to discuss the current understanding of PND and evidence regarding effective treatment strategies.

RESUMEN

Objective: Obstructive Sleep Apnea-Hypopnea Syndrome (OSAHS) and Laryngopharyngeal Reflux Disease (LPRD) are interrelated medical conditions affecting the respiratory system. This article aimed to investigate the potential correlation between the two. Methods: This cross-sectional study was carried out on a total of 52 participants diagnosed with both OSAHS and LPRD. Clinical data of baseline demographics of year, sex, BMI, including clinical indicators such as AHI (Apnea Hypopnea Index), OSAHS severity grading, RFS (Reflux Finding Score), RSI (Reflux Symptom Index), and 24-hour pH level were collected. Statistical analysis was then conducted to evaluate the correlation between OSAHS and LPRD. Results: Among the 52 patients, the the average age was 43.3±11.6 years with a mean 24.7±2.9 kg/m2 BMI level. The mean duration of OSAHS was 4.1±1.7 years with mean 38.7±12 AHI scores and 30.8% mild OSAHS, 51.9% moderate OSAHS, and 17.3% severe OSAHS. Mean LPRD duration was 3.2±1.5 years with a mean 15.9±4.9 RFS score, mean 28.0±6.8 RSI score, and mean 3.9±0.8 24-hour pH level. There was a strong positive correlation between AHI scores and both the RFS score (r>0.9, P < .01) and RSI score (r>0.9, P < .01). While a strong negative correlation between AHI scores and 24-hour pH level was observed (r < -0.8, P < .01). And there was a strong positive correlation between OSAHS severity levels and both the RSF score (r>0.8, P < .01) and RSI score (r>0.79, P < .01). While a significant negative correlation between OSAHS severity and 24-hour pH level was detected (r < -0.7, P < .01). Conclusions: The findings of this cross-sectional study demonstrate a strong positive correlation between the severity of OSAHS, as indicated by AHI scores, and the severity of LPRD, as measured by RFS and RSI scores. A negative correlation was also observed between AHI scores and 24-hour pH level, indicating a connection between these two medical conditions.

RESUMEN

BACKGROUND: Laryngopharyngeal reflux (LPR) is one of the most common disorders in otorhinolaryngology, affecting up to 10% of outpatients visiting otolaryngology departments. In addition, 50% of hoarseness cases are related to LPR. Pepsin reflux-induced aseptic inflammation is a major trigger of LPR; however, the underlying mechanisms are unclear. The nucleotide-binding domain and leucine-rich repeat protein 3 (NLRP3) inflammasome has become an important bridge between stimulation and sterile inflammation and is activated by intracellular reactive oxygen species (ROS) in response to danger signals, leading to an inflammatory cascade. In this study, we aimed to determine whether pepsin causes LPR-associated inflammatory injury via mediating inflammasome activation and explore the potential mechanism. METHODS: We evaluated NLRP3 inflammasome expression and ROS in the laryngeal mucosa using immunofluorescence and immunohistochemistry. Laryngeal epithelial cells were exposed to pepsin and analyzed using flow cytometry, western blotting, and real-time quantitative PCR to determine ROS, NLRP3, and pro-inflammatorycytokine levels. RESULTS: Pepsin expression was positively correlated with ROS as well as caspase-1 and IL-1ß levels in laryngeal tissues. Intracellular ROS levels were elevated by increased pepsin concentrations, which were attenuated by apocynin (APO)-a ROS inhibitor-in vitro. Furthermore, pepsin significantly induced the mRNA and protein expression of thioredoxin-interacting protein, NLRP3, caspase-1, and IL-1ß in a dose-dependent manner. APO and the NLRP3 inhibitor, MCC950, inhibited NLRP3 inflammasome formation and suppressed laryngeal epithelial cell damage. CONCLUSION: Our findings verified that pepsin could regulate the NLRP3/IL-1ß signaling pathway through ROS activation and further induce inflammatory injury in LPR. Targeting the ROS/NLRP3 inflammasome signaling pathway may help treat patients with LPR disease.

RESUMEN

OBJECTIVE: To develop and validate the Reflux Sign Assessment-10 (RSA-10) for documenting the physical findings of laryngopharyngeal reflux disease (LPRD). METHODS: Patients with LPRD at the hypopharyngeal-esophageal multichannel intraluminal impedance-pH monitoring and asymptomatic individuals were consecutively recruited from two European hospitals. Three experienced otolaryngologists rated RSA-10 in patients and controls for assessing internal validity. RSA-10 was rated within a 7-day period to assess test-retest reliability. Internal consistency was measured using Cronbach's α in patients and controls. Convergent validity was evaluated through a correlation analysis between RSA-10 and Reflux Finding Score (RFS). Interrater reliability was evaluated by comparing the RSA-10 evaluations of the three otolaryngologists through Fleiss kappa. Pre- to posttreatment change of RSA-10 was evaluated to assess responsiveness to change. The RSA-10 thresholds were examined by receiver operating characteristic analysis. RESULTS: Fifty-five patients completed the pre- to posttreatment evaluations from January 2020 to December 2023. A total of 115 asymptomatic individuals completed the study. RSA-10 reported high internal consistency reliability (α = 0.822) and test-retest reliability (rs = 0.725). The RSA-10 scores of patients were significantly higher than those of controls (p = 0.001), suggesting high internal validity. RSA-10 was significantly correlated with the RFS (rs = 0.771). The interrater reliability was adequate for sub- and total RSA-10 scores (k = 0.708). RSA-10 significantly improved from baseline to 3-month posttreatment (p = 0.001). An RSA-10 > 13 may be suggestive of LPRD. Both RSA-10 > 13 and Reflux Symptom Score-12 > 11 were associated with a sensitivity of 92.7% and a specificity of 97.3%. CONCLUSION: The RSA-10 is a reliable and valid clinical instrument for documenting the most prevalent laryngeal and extra-laryngeal findings associated with LPRD.

RESUMEN

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.

RESUMEN

Bile acids in refluxate contribute to esophageal and laryngeal symptoms and are quantifiable. The aim of this study was to compare salivary bile acid concentrations across healthy controls and symptomatic patients (esophageal or laryngeal) with or without objective gastroesophageal reflux disease (GERD). This prospective study enrolled adults into three groups: esophageal symptoms (heartburn, regurgitation, chest pain); laryngeal symptoms (cough, throat clearing, sore throat, dysphonia); and controls. Symptomatic patients primarily underwent prolonged wireless reflux monitoring off acid suppression and were categorized as symptomatic no GERD (acid exposure time <4%) or esophageal/laryngeal symptoms with GERD (acid exposure time ≥4%). Controls did not undergo reflux monitoring nor upper endoscopy. Saliva samples were provided for bile acid analysis via ultraperformance liquid chromatography tandem mass spectrometry. Thirty-five participants were enrolled (mean age 47.4 years [SD 18.9], 16 [46%] male), including 10 controls and 25 symptomatic: 9 no GERD, 5 esophageal symptoms + GERD, and 11 laryngeal symptoms + GERD. Total salivary bile acids were highest in the laryngeal symptoms + GERD group (24.2 nM [SD 24.7]) compared to other groups (controls: 5.8 [6.0], P = 0.03; symptomatic no GERD: 3.1 [4.4]; P < 0.01; esophageal symptoms + GERD: 7.1 [7.1], P = 0.10). Bile acids were elevated in 45% (5/11) of the laryngeal symptoms + GERD group compared to 0% of the other three groups (P < 0.01). Salivary bile acids were higher among patients with laryngeal symptoms and objective GERD versus other groups. Salivary bile acids are a quantifiable biomarker with diagnostic potential for laryngopharyngeal reflux.
