Is it Always Laryngopharyngeal Reflux? How Voice Disorders Can Manifest as LPR

Introduction: Laryngopharyngeal reflux (LPR) manifests with a constellation of common throat symptoms and inconclusive signs on laryngoscopic exam. It is a diagnosis, often made clinically, that can lead to prescriptions of proton pump inhibitors that are unnecessary and potentially harmful. Glottic insufficiency (GI) and the accompanying hyperfunctional laryngeal behaviors can also present with similar, common throat complaints that may or may not include a qualitative change to the voice. Methods: This is a reflection article. It is written to summarize, explain, and support with evidence the opinion of the author on the topic of how symptoms of voice disorders can easily be mistaken for symptoms of LPR. The offered reflection is based on his experience, research and the available literature. Reflection: This article intends to explore the similarities between GI and LPR, how to ultimately differentiate them and how to approach treatment with a broader differential diagnosis. Conclusion: LPR and GI can present with identical, vague throat, and voice symptoms. Empiric medication trials, behavioral interventions and objective laryngovideostroboscopy, impedance-based reflux, and esophageal motility testing may all be needed, sometimes in a trial and error fashion, to correctly diagnose and treat a patient's symptoms.

Introducción: El reflujo laríngeo-faríngeo (LPR, por sus siglas en inglés) se manifiesta con una serie de síntomas comunes en la garganta y signos no concluyentes en el examen larinoscópico. Es un diagnóstico que a menudo se realiza clínicamente y que puede llevar a la prescripción de inhibidores de la bomba de protones que son innecesarios y potencialmente perjudiciales. La insuficiencia glótica (IG) y los comportamientos laríngeos hiperfuncionales que la acompañan también pueden presentar síntomas de garganta comunes similares, que pueden o no incluir un cambio cualitativo en la voz. Métodos: Este es un artículo de reflexión. Está escrito para resumir, explicar y respaldar con evidencia la opinión del autor sobre cómo los síntomas de los trastornos de la voz pueden confundirse fácilmente con los síntomas del LPR. La reflexión ofrecida se basa en su experiencia, investigación y la literatura disponible. Reflexión: Este artículo tiene la intención de explorar las similitudes entre la IG y el LPR, cómo diferenciarlos finalmente y cómo abordar el tratamiento con un diagnóstico diferencial más amplio. Conclusión: El LPR y la IG pueden presentar síntomas idénticos y vagos en la garganta y la voz. Puede ser necesario realizar ensayos de medicación empírica, intervenciones conductuales y pruebas objetivas de laringovideostroboscopia, reflujo basado en impedancia y motilidad esofágica, a veces de manera experimental, para diagnosticar y tratar correctamente los síntomas de un paciente.

Diagnostic utility of salivary pepsin in laryngopharyngeal reflux: a systematic review and meta-analysis

Abstract Objective: Salivary pepsin has emerged as a biomarker for Laryngopharyngeal Reflux (LPR), which, however, has been questioned for its efficacy due to a lack of supporting medical data. Therefore, this study analyzed the diagnostic value of salivary pepsin for LPR and assessed a better cutoff value. Methods: Studies were searched in PubMed, Embase, and Cochrane Library from their receptions to October 1, 2021. Then, RevMan 5.3 and Stata 14.0 were utilized to summarize the diagnostic indexes for further meta-analysis. Data were separately extracted by two reviewers according to the trial data extraction form of the Cochrane Handbook. The risk of bias in Randomized Control Trials (RCTs) was evaluated with the Cochrane Risk of Bias Tool. Results: A total of 16 studies matched the criteria and were subjected to meta-analysis. The results revealed a pooled sensitivity of 61% (95% CI 50%-71%), a pooled specificity of 67% (95% CI 48%-81%), a positive likelihood ratio of 2 (95% CI 1.2-2.8), a negative likelihood ratio of 0.58 (95% CI 0.47-0.72), and the area under the receiver operating characteristic curve of 0.67 (95% CI 0.63-0.71). Subgroup analyses indicated that the cutoff value of pepsin at 50 ng/mL had a higher degree of diagnostic accuracy than that of pepsin at 16 ng/mL in cohort studies. Conclusion: The review demonstrated low diagnostic performance of salivary pepsin for LPR and that the cutoff value of 50 ng/mL pepsin had superior diagnostic accuracy. Nevertheless, the diagnostic value may vary dependent on the utilized diagnostic criteria. Therefore, additional research is needed on the improved way of identifying salivary pepsin in the diagnosis of LPR, and also longer-term and more rigorous RCTs are warranted to further assess the effectiveness of salivary pepsin.

The link between airway reflux and non-acid reflux in children: a review

Abstract Objective: Airway reflux, a member of extra-esophageal reflux, has been linked to countless respiratory pathologies amongst children. The advent of novel instrumentation has enabled the discovery of non-acid reflux which was postulated as the main culprit of airway reflux. The objective of this review is to outline the association between non-acid reflux and airway reflux in children. Methods: A comprehensive review of recent literature on non-acid reflux and airway reflux in children was conducted. Studies ranged from January 2010 till November 2021 were searched over a period of a month: December 2021. Results: A total of eleven studies were identified. All studies included in this review revealed a strong link between non-acid reflux and airway reflux in children. 6 of the included studies are prospective studies, 3 retrospective studies, 1 cross-section study, and type of study was not mentioned in 1 study. The most common reported respiratory manifestation of non-acid reflux in children was chronic cough (7 studies). Predominant non-acid reflux was noted in 4 studies. The total number of children in each study ranges from 21 to 150 patients. MII-pH study was carried out in all studies included as a diagnostic tool for reflux investigation. Conclusion: Non-acid reflux is the culprit behind airway reflux as well as other myriads of extra-esophageal manifestations in children. Multicentre international studies with a standardized protocol could improve scientific knowledge in managing non-acid reflux in airway reflux amongst children.

Translation and cultural adaptation of the Short Version of the Reflux Symptom Score: Reflux Symptom Score-12 into Brazilian Portuguese

Abstract Objective: To describe the process of translation into Brazilian Portuguese and cross-cultural adaptation of the French Reflux Symptom Score-12 questionnaire used for the diagnosis of laryngopharyngeal reflux. Methods: This was across-cultural translation and adaptation study of a health instrument, with a cross-sectional design. It was carried out in eight stages: translation from French into Brazilian Portuguese, cultural adaptation by a panel of experts, application of the first version (pilot test 1), adaptation by a panel of experts, application of the second version (pilot test 2), back translation, reviewing by a committee in conjunction with the author of the original instrument and, application of the final version. The Brazilian Portuguese versions of the questionnaire were applied to individuals with symptoms and signs of laryngopharyngeal reflux who underwent pHmetry and esophageal manometry at the study site. Results: In pilot test 1, the first version of the RSS-12 in Brazilian Portuguese was applied to 30 patients. The patients had no difficulty to understand any of the 12 symptom items, but 15 patients (50%) had difficulty interpreting the symptom frequency score. After adapting the format of the frequency score, a version 2 of the RSS-12 in Brazilian Portuguese was applied to another 23 patients, who completed the questionnaire in full without any difficulty. Along with the review committee, the author of the original RSS-12 considered the version 2 to be adequate and did not propose any changes, so it was approved as the final version of the Brazilian Portuguese RSS-12. Conclusion: The Brazilian Portuguese version of the instrument, called Reflux Symptom Score-12 PT-BR, shows good understanding and linguistic, conceptual and content equivalence, in relation to the original Reflux Symptom Score-12.

The application progress on diagnostic scales of laryngopharyngeal reflux disease / 临床耳鼻咽喉头颈外科杂志

At present, objective methods for diagnosing laryngopharyngeal reflux disease(LPRD) are not minimally invasive, effective, and economical. Diagnostic scales are widely used worldwide due to the advantages of inexpensive, noninvasive, and easy to operate. The reflux symptom index(RSI) and the reflux finding score(RFS) are preferred to use in clinical diagnosis. However, many controversies have appeared in the application of RSI and RFS in recent years, causing many troubles to clinical diagnosis. Therefore, this review briefly discusses the problems of RSI and RFS in clinical applications to provide reference for diagnosing LPRD accurately.

Analysis on the pharyngeal microbiota in patients with laryngopharyngeal reflux disease

Abstract Objective(s): In this study, the laryngopharynx microbiome alterations were characterized after proton pump inhibitor treatment in patients with Laryngopharyngeal Reflux Disease (LPRD) and healthy people. The potential outcome-predictive biomarker was explored. Methods: Patients with LPRD and healthy controls were enrolled. The composition of their laryngopharynx microbiota was analyzed both by traditional plate count of the main bacterial groups and PCR amplification followed by denaturing gradient gel electrophoresis. Shannon-Wiener index and evenness index based on Dice index were used to assess the bacterial diversity. Droplet digital PCR was used to determine the total bacterial RNA and relative abundance of Klebsiella oxytoca. Receiver operating characteristic curve was plotted to explore the potential of Klebsiella oxytoca as an outcome-predictive biomarker. Results: A total of 29 LPRD cases and 28 healthy subjects were enrolled. The composition of the laryngopharynx microbiota was almost similar, except Klebsiella oxytoca. The cluster analysis showed that the similarity between healthy and treatment-effective groups, as well as pretreatment and treatment-invalid groups, was close. Statistical analysis showed that there were differences in the diversity index and richness among the healthy, treatment-effective, pretreatment and treatment-invalid groups. The abundance of Klebsiella oxytoca in the treatment-effective LPRD group was lower than that of the treatment-invalid LPRD group. The abundance of Klebsiella oxytoca can distinguish treatment-effective and -invalid groups (AUC = 0.859) with a sensitivity of 77.78% and specificity of 90.91%. Conclusion: There were differences in the diversity of cecal contents microbial community between treatment-invalid and treatment-effective LPRD groups. Klebsiella oxytoca has potential to distinguish treatment outcomes. Level of evidence: How common is the problem? Level 1. Is this diagnostic or monitoring test accurate? (Diagnosis) Level 4. What will happen if we do not add a therapy? (Prognosis) Level 5. Does this intervention help? (Treatment Benefits) Level 4. What are the COMMON harms? (Treatment Harms) Level 4. What are the RARE harms? (Treatment Harms) Level 4. Is this (early detection) test worthwhile?(Screening) Level 4.

Using RSI and RFS scores to differentiate between reflux-related and other causes of chronic laryngitis

Abstract Objective: To establish if the Reflux Symptom Index (RFI) and the Reflux Finding Score (RFC) can help establish the differential diagnosis in patients with distinct causes of chronic laryngopharyngitis. Methods: A group of 102 adult patients with chronic laryngopharyngitis (Group A - 37 patients with allergic rhinitis; Group B - 22 patients with Obstructive Sleep Apnea (OSA); Group C -43 patients with Laryngopharyngeal Reflux (LPR)) were prospectively studied. Chronic laryngitis was diagnosed based on suggestive symptoms and videolaryngoscopic signs (RSI ≥ 13 and RFS ≥7). Allergies were confirmed by a positive serum RAST, OSA was diagnosed with a positive polysomnography, and LPR with a positive impedance-PH study. Discriminant function analysis was used to determine if the combination of RSI and RFS scores could differentiate between groups. Results: Patients with respiratory allergies and those with LPR showed similar and significantly higher RSI scores when compared to that of patients with OSA (p < 0.001); Patients with OSA and those with LPR showed similar and significantly higher RFS scores when compared to that of patients with Respiratory Allergies (OSA vs. Allergies p < 0.001; LPR vs. Allergies p < 0.002). The combination of both scores held a higher probability of diagnosing OSA (72.73%) and Allergies (64.86%) than diagnosing LPR (51.16%). Conclusions: RSI and RFS are not specific for reflux laryngitis and are more likely to induce a false diagnosis if not used with diligence.

Correlación diagnóstica entre fibrolaringoscopia y videoendoscopia digestiva alta en pacientes con reflujo gastroesofágico y reflujo laringofaríngeo / Diagnostic Correlation Between Fiberlaringoscopy and Upper Gastrointestinal Video Endoscopy in Patients with Gastroesophagic Reflux and Laryngopharyngeal Reflux

Introducción: el reflujo laringofaríngeo (RLF) se origina por el flujo retrógrado de contenido gástrico hacia la faringe, pero es una entidad diferente de la enfermedad por reflujo gastroesofágico (ERGE). El objetivo del estudio fue determinar la correlación entre los signos endoscópicos de la fibrolaringoscopia y la videoendoscopia digestiva alta (VEDA). Material y métodos: estudio observacional, retrospectivo y analítico. Se incluyeron pacientes que consultaron por sintomatología de RLF y ERGE. Los hallazgos visualizados por fibrolaringoscopia flexible, VEDA y biopsia de mucosa gástrica de cada paciente se compararon con la prueba de chi-cuadrado (χ²). Se consideró significativo un valor de p ≤ 0,05. Resultados: se incluyeron 318 pacientes entre 18 y 84 años. Se encontró que el 100 % de los pacientes con esofagitis tenía laringitis (p = 0,001); el 100 % de los pacientes con hernia hiatal tenían RLF (p = 0,001); el 97 % de los pacientes con Helicobacter pylori en la mucosa gástrica tenían RLF (p = 0.001). El 71 % de los pacientes con hernia hiatal tenían esofagitis (p = 0,001). Se encontró una asociación lineal entre la edad y la hernia hiatal con la edad y el RLF (p = 0,03). Conclusiones: en este estudio, los signos encontrados en la fibrolaringoscopia tuvieron una asociación estadística con la VEDA. Aproximadamente el 90 % de los pacientes con signos de laringitis tuvo una correlación con algún grado de esofagitis, esófago de Barrett, hernia hiatal y Helicobacter pylori. También se encontró que la laringitis por RLF y la hernia hiatal se relacionaron directamente con el incremento de la edad.

Introduction: Laryngopharyngeal reflux (LPR) is caused by the retrograde flow of gastric contents towards the pharynx, but it is a different entity from gastroesophageal reflux disease (GERD). The objective of the study was to determine the relationship between the endoscopic signs of fiber laryngoscopy and upper gastrointestinal video endoscopy. Material and methods: Observational, retrospective and analytical study. Patients who consulted for LPR and GERD symptoms were included. The findings visualized by flexible fiber laryngoscopy, upper gastrointestinal video endoscopy and gastric mucosal biopsy of each patient were compared with the Chi-square (χ²) test. A value of p ≤ 0.05 is estimated significantly. Results: 318 patients between 18 and 84 years old were included. A relationship was found in 100% of the patients with esophagitis had laryngitis (p = 0.001); 100% of the patients with hiatal hernia had LPR (p = 0.001); 97% of patients with Helicobacter pylori in the gastric mucosal have LPR (p= 0.001); 71% of patients with hiatal hernia had esophagitis (p = 0.001). A linear association was found between age and hiatal hernia with age and LPR. (p = 0.03). Conclusions: In this study, the signs found in fiber laryngoscopy had a statistical association with the upper gastrointestinal video endoscopy. Approximately 90% of patients with signs of laryngitis had correlation with some degree of esophagitis, Barrett's esophagus, hiatal hernia and Helicobacter pylori. It was also found that LPR and hiatal hernia were directly related to increasing age

Desvio vocal em indivíduos com sinais e sintomas sugestivos de refluxo laringofaríngeo / Vocal deviation in individuals with suggestive signs and symptoms of laryngopharyngeal reflux

RESUMO Objetivo verificar e comparar o desvio da qualidade vocal, sintomas vocais e índice de sintomas de refluxo em pacientes com diagnóstico clínico sugestivo de refluxo laringofaríngeo (RLF). Método participaram deste estudo prospectivo 100 indivíduos de ambos os sexos, com faixa etária entre 18 e 60 anos que apresentaram sinais de RLF no exame nasofibrolaringológico. Os participantes responderam ao questionário Índice de Sintomas do Refluxo Faringo-Laríngeo (ISRFL) para determinar presença de sintomas de refluxo e a Escala de Sintomas Vocais (ESV). Tiveram suas vozes gravadas para a avaliação perceptivoauditiva. Foram contatadas três fonoaudiólogas com experiência em voz e manteve-se a de maior confiabilidade. Resultados 100 vozes avaliadas, 34 eram adaptadas e 66 desviadas. O tipo de qualidade vocal predominante foi rugoso e o grau de desvio leve. A média dos escores no ESV e ISRFL dos indivíduos com vozes desviadas foi significativamente maior que no grupo de vozes adaptadas em ambos os protocolos (p<0,01). O sintoma relatado com maior frequência e intensidade, em ambas as avaliações, foi pigarro. Houve diferenças estatisticamente significativas quando analisados os pares dos tipos de qualidade vocal: rugosa-adaptada (p=0,0021) e tensa-adaptada (p=0,0075) no ESV, e rugosa-adaptada (p=0,001) no ISRFL. Conclusão indivíduos com vozes desviadas referiram maior ocorrência de sinais e sintomas vocais relacionadas ao RLF mensurados pela ESV e ISRFL. As inúmeras teorias a respeito da doença não tornam possível uma única conclusão sobre o assunto. São necessários novos estudos na área a fim de auxiliar o profissional no diagnóstico e tratamento do paciente com RLF.

ABSTRACT Purpose Verify and compare vocal deviation in quality, vocal symptoms and reflux symptom index in patients with clinical diagnosis of laryngopharyngeal reflux (LPR). Methods 100 individuals of both genders participated in this prospective study, aged between 18 and 60 years old, who presented signs of LPR in the nasofibrolaryngological exam. Participants answered the Reflux Symptom Index (RSI) questionnaire to determine the reflux index and the Voice Symptom Scale (VoiSS). Their voices were recorded for the auditory-perceptual assessment. Three speech therapists with voice experience were contacted and the most reliable one was maintained. Results 100 examined voices, 34 were classified as adapted and 66 as deviated. The predominant vocal quality type was rough and a slight degree of deviation. The average score on VoiSS and RSI of individuals with deviated voice is significantly higher than the adapted voice group on both protocols (p<0.01). The symptom reported with most frequency and intensity, in both analyses, was throat clearing. There were statistically significant differences once analyzed the vocal quality types by pairs: rough-adapted (p=0.0021) and tense-adapted (p=0.0075) on VoiSS, and rough-adapted (p=0.001) on RSI. Conclusion Individuals with deviated voice reported higher occurrence of LPR related vocal signals and symptoms measured by VoiSS and RSI. The numerous theories about the disease do not make possible a single conclusion on the subject. Further studies are needed in the area to assist the professional in the diagnosis and treatment of the RLF patient.

Clinical, endoscopic and histological characteristics of heterotopic gastric mucosa in upper esophagus / 中华消化内镜杂志

Objective:To study the clinical, endoscopic and histological characteristics of heterotopic gastric mucosa in upper esophagus (HGMUE).Methods:A Total of 177 patients who underwent gastroscopy and were diagnosed as having HGMUE at the Endoscopy Center of Wuhan Union Hospital from January 2017 to December 2017 were included in the study. According to the gastroesophageal reflux disease symptom questionnaire (GERD-Q) scores, patients were divided into the HGMUE group (GERD-Q<8, n=101) and GERD+HGMUE group (GERD-Q≥8, n=76). The data of clinical, endoscopic and histological characteristics were analyzed. Results:Among the 177 HGMUE cases, there were 111 males (62.71%) and 66 females (37.29%), 76 (42.94%) with GERD, and 101 (57.06%) without GERD. The most common symptom was continuous clearing throat [54.24% (96/177)], followed by foreign body sensations of throat [48.59% (86/177)], and gastroesophageal reflux symptoms such as heartburn, chest pain, indigestion, acid reflux [48.59% (86/177)]. In the HGMUE group, the occurrence rate of clearing throat was the highest [42.57% (43/101)], then foreign body sensations of throat accounted for 33.66% (34/101), and gastroesophageal reflux symptoms was 27.72% (28/101). In the HGUME+GERD group, the most common symptom was gastroesophageal reflux symptoms [76.32% (58/76)], then clearing throat [69.74% (53/76)] and foreign body sensations of throat [68.42% (52/76)]. Under gastroscopy, 177 heterotopic gastric lesions were found under gastroscopy with orange-red round, oval or elongated island like ones, most of which were flat and a few slightly protruded from the peripheral plane. There were 132 (74.58%) single-lesion cases, 38 (21.47%) 2-lesion, and 7 (3.95%) 3- or more-lesion cases; there were 37 (20.90%) small lesions (maximum diameter <0.5 cm), and 74 (41.81%) median-size lesions (maximum diameter of 0.5-1.0 cm), and 66 (37.3%) larger lesions (maximum diameter >1.0 cm). Among the 30 [16.95% (30/177)] samples of mucosal tissue, 15 [50.00% (15/30)] were mainly cardia gland, 8 [26.67% (8/30)] were mainly pyloric gland, 6 [20.00% (6/30)] were mixed type, and 1 [3.33% (1/30)] was squamous epithelium. In the immunohistochemical test, 20 cases [66.67% (20/30)] showed positive of H +/K +-ATPase, and 10 cases [33.33% (10/30)] were negative. Conclusion:HGMUE is more common in male patients, and may be combined with GERD. Among them, patients with combined GERD are more likely to develop laryngopharyngeal reflux. The heterotopic gastric mucosas lesions are orange-red round, oval or elongated island-like under gastroscopy, and most of them are flat, single and median- or large-sized. Histological types are mostly fundic glands, and H +/K +-ATPase positive is more common. It is speculated that acid secretion may be an important factor leading to throat symptoms.

Laryngopharyngeal Reflux: Symptoms, Signs, and Presence of Pepsin in Saliva - A Reliable Diagnostic Triad

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.

Importance of esophageal pH monitoring and manometry in indicating surgical treatment of gastroesophageal reflux disease

SUMMARY OBJECTIVE: To demonstrate the need of performing esophageal pH monitoring and manometry in patients with clinical suspicion of Gastroesophageal reflux disease, as more accurate and practical complementary exams in the indication of surgical treatment. METHODS: A systematic review was carried out in the PubMed/Medline database, based on the recommendations of the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol, selecting studies in humans, published in Portuguese, Spanish, and English, from January 1, 2009 to August 5, 2020. The following descriptors were used: "reflux gastroesophageal" AND "surgery" AND "surgical treatment" AND "esophageal manometry" OR "pH monitoring". After that, retrospective or prospective observational studies with a sample of less than 100 individuals, or with limited access, reports or case series, review articles, letters, comments, or book chapters were excluded. To facilitate the application of the exclusion criteria, the Rayyan management base was used. RESULTS: Out of the 676 studies found, 19 valid and eligible studies were selected to make inferences. CONCLUSIONS: Based on the best evidence, currently, considering national particularities, performing a 24-hour esophageal pH monitoring and esophageal manometry for all patients undergoing anti-reflux surgery.

Evaluation of the Reflux Symptom Index and the Endolaryngeal Findings Scale after Treatment in Individuals with Laryngopharyngeal Reflux

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.

Therapeutic efficacy observation of acupuncture plus medicine for laryngopharyngeal reflux due to liver-qi stagnation and spleen deficiency / 针灸推拿医学（英文版）

Objective: To observe the clinical efficacy of acupuncture plus medicine in treating laryngopharyngeal reflux due to liver-qi stagnation and spleen deficiency. Methods: A total of 70 patients were divided into a control group and an observation group by the random number table method, with 35 cases in each group. Both groups were treated with conventional medications, and the observation group was treated with additional acupuncture therapy. The reflux symptom index (RSI) and reflux finding score (RFS) were evaluated. Esophageal motility indicators such as lower esophageal sphincter pressure (LESP) and upper esophageal sphincter pressure (UESP), and salivary pepsin level were measured. The clinical efficacy was also compared. Results: The total effective rate of the observation group was higher than that of the control group (P<0.05). After treatment, the RSI and RFS scores in both groups decreased significantly (all P<0.05), and the RSI and RFS scores in the observation group were significantly lower than those in the control group (both P<0.05). There were no significant changes in the LESP and UESP in the control group (both P>0.05), while LESP and UESP in the observation group increased significantly (both P<0.05), and higher than those in the control group (both P<0.05). The salivary pepsin levels in both groups decreased (both P<0.05), and the salivary pepsin level in the observation group was significantly lower than that in the control group (P<0.05). Conclusion: Acupuncture plus medicine can improve symptoms and signs in patients with laryngopharyngeal reflux due to liver-qi stagnation and spleen deficiency, and regulate esophageal motility and salivary pepsin level. Its efficacy is more significant compared with medicine alone.

Effect of laryngopharyngeal reflux on sedation-related adverse events in patients undergoing painless gastroscopy / 中华麻醉学杂志

Objective:To evaluate the effect of laryngopharyngeal reflux on sedation-related adverse events in the patients undergoing painless gastroscopy.Methods:Two hundred and eighty-nine American Society of Anesthesiologists physical status Ⅰ-Ⅲ patients of both sexes, aged 18-75 yr, with body mass index 18.5-28.0 kg/m 2, scheduled for elective painless gastrocopy, were selected.Specimens of glottic secretions before and after gastroscopy were collected, and the concentration of human pepsin was measured by enzyme-linked immunosorbent assay.The patients in whom the concentration of pepsin was positive before the examination were excluded (the concentration ≥ 31.34 pg/ml was considered as positive). The patients were divided into laryngopharyngeal reflux group (R group, the concentration of pepsin was positive after gastroscopy) and non-laryngopharyngeal reflux group (N group, the concentration of pepsin was negative after gastroscopy) according to the concentration of pepsin in the secretion samples before and after gastroscopy.The occurrence of hypoxemia, hypotension, bradycardia, bucking and body movement during operation was recorded.The patients were followed up by telephone on the 1st, 3rd and 7th days after operation.The sore throat, hoarseness, nausea and vomiting, cough and expectoration and use of antibiotics were recorded. Results:Compared with group N, the incidence of bucking and hypoxemia was significantly increased, the incidence of sore throat and hoarseness was increased on the 1st day after operation, and the incidence of cough and expectoration was increased on the 1st and 3rd days after gastroscopy in group R ( P<0.05). Conclusion:Laryngopharyngeal reflux can increase the development of intraoperative and postoperative sedation-related adverse events in the patients undergoing painless gastroscopy.

Clinical study of laryngopharyngeal reflux treated with acupuncture on the base of theory of the ascending and the descending of / 中国针灸

OBJECTIVE@#To verify the clinical effect of laryngopharyngeal reflux (LPR) treated with acupuncture at the acupoints composed on the base of theory of the ascending and the descending of .@*METHODS@#A total of 84 patients of LPR were randomized into an observation group and a control group, 42 cases in each one. The conventional treatment was provided in the two groups. Additionally, in the control group, the medication was administered, i.e. esomeprazole tablets (20 mg, twice a day) and mosapride tablets (5 mg, three times a day), consecutively for 14 days. In the observation group, the oral medication was the same as the control group. Besides, acupuncture at the acupoints composed on the base of theory of the ascending and the descending of was supplemented. The acupoints were Tiantu (CV 22), Danzhong (CV 17), Zhongwan (CV 12), Zusanli (ST 36), Taichong (LR 3) and Neiguan (PC 6). The acupuncture treatment was given once a day, 5 times a week, consecutively for 10 times in 2 weeks (14 days in total). Before and after treatment, the reflux symptom index (RSI) score, the reflux finding score (RFS) and the time proportion of esophageal pH < 4 in 24 h were compared, and the therapeutic effect was evaluated in the two groups.@*RESULTS@#After treatment, RSI score, RFS, 24 h esophageal pH<4 time proportion were all reduced as compared with those before treatment in the two groups (<0.05). After treatment, RSI score, RFS, 24 h esophageal pH<4 time proportion in the observation group were lower than those in the control group (<0.05). The total effective rate was 92.9% (39/42) in the observation group, better than 71.4% (30/42) in the control group (<0.05).@*CONCLUSION@#On the base of the conventional treatment, acupuncture at the acupoints composed in compliance with the theory of the ascending and the descending of combined with western medication contribute to the recovery of gastrointestinal function, effectively control the laryngopharyngeal symptoms and physical signs.

Correlation analysis between Dx-pH monitoring and proton pump inhibitor test in the diagnosis of laryngopharyngeal reflux disease / 中华耳鼻咽喉头颈外科杂志

Objective@#The consistency of 24-hour oropharyngeal Dx-pH monitoring and proton pump inhibitor(PPI) test in the diagnosis of laryngopharyngeal reflux disease (LPRD) was investigated.@*Methods@#Sixty patients with laryngopharyngeal reflux (LPR) related symptoms who had never received PPI treatment were assessed by reflux symptom index (RSI) and reflux finding score (RFS) between October 2017 and October 2018, including 28 males and 38 females, aged from 16 to 72 years, with a medium age of 38 years. Prior to treatment, all patients were evaluated with 24 hours oropharyngeal Dx-pH monitoring(Restech). After empiric therapy with PPI twice-daily for 8 weeks, the efficacy was evaluated according to posttreatment RSI score.The data was analysed with Kruskal-Wallis test, Student Newman Keuls test and consistency check.@*Results@#(1)Among all 60 patients,13 patients (21.7%) had pathologic Ryan score and all resulted responsive to PPI;27 patients (45.0%) with a negative Ryan score were unresponsive to PPI; 20 patients (33.3%) despite a negative Ryan score resulted responsive to PPI therapy. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of Ryan score were 39.4%, 100%, 100% and 57.4% respectively. The Kappa value was 0.369 (P<0.01). (2)Among 34 patients (56.7%) with positive Dx-pH results (24-hour oropharyngeal acid reflux events≥ 3 times), 29 patients were positive and 5 patients were negative in PPI test. Among 26 patients with negative Dx-pH results (24-hour oropharyngeal acid reflux events<3 times), 4 patients were positive and 22 patients were negative in PPI test. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of 24-hour oropharyngeal acid reflux events were 87.9%, 81.5%, 85.3% and 84.6% respectively. The Kappa value was 0.696(P<0.01).@*Conclusions@#There is a positive correlation between 24-hour oropharyngeal Dx-pH monitoring positive results (24-hour oropharyngeal acid reflux events≥3 times) and PPI test in the diagnosis of LPRD. The 24-hour oropharyngeal Dx-pH monitoring can be a promising tool for the diagnosis of suspected LPRD patients, and more sensitive and accurate Dx-pH diagnostic index will be required in the clinic.

The influence of age on the score of reflux symptom index scale and reflux finding score scale in the diagnosis of pharyngeal and laryngeal reflux / 临床耳鼻咽喉头颈外科杂志

The aim of this study is to determine the accuracy of RSI and RFS in the diagnosis of hypopharyngeal reflux （LPR）, the scores of RSI and RFS were compared in different age groups. To explore the RSI and RFS scoring thresholds for diagnosis of LPR in different age groups. From January 2017 to March 2019, 258 patients with suspected LPR in our hospital outpatient clinic completed the RSI and RFS scales. According to their age, 258 patients with RSI>13 and RFS>7 were selected. They were divided into group A （18-0.05）, RSI score was significantly different （<0.05）, RSI score of group A and group B was higher than that of group C （<0.05）. According to ROC analysis, the best RSI cutoffs for diagnosing LPR in group C was 11, and the area under the ROC curve was 0.866. The RSI score is a good criterion for the diagnosis of LPR. The diagnostic threshold of RSI in elderly patients is different from that in young patients. For elderly patients, the diagnostic threshold for the recommended RSI score is 11.

Clinical and polysomnographic predictors of laryngopharyngeal reflux in obstructive sleep apnea syndrome / Avaliação do refluxo laringofaríngeo na síndrome da apneia obstrutiva do sono

Abstract Introduction Obstructive sleep apnea syndrome and laryngopharyngeal reflux are diseases with a high prevalence in the overall population; however, it remains unclear whether they are diseases with the same risk factors present in the same populations or if there is any association between them. Objectives To evaluate and determine the prevalence of laryngopharyngeal reflux in patients with moderate and severe obstructive apnea syndrome and also to determine its predictive factors. Methods Historical cohort, cross-sectional study of patients aged 18-70 years, referred to a tertiary service Otorhinolaryngology outpatient clinic with a polysomnographic diagnosis of moderate or severe obstructive sleep apnea syndrome. The reflux symptom index questionnaire and the reflux finding score at indirect videolaryngoscopy were applied to the assessed population, considering the inclusion and exclusion criteria. Results Fifty-six patients were evaluated, of which 64.3% had a positive laryngopharyngeal reflux (positive reflux symptom index and/or positive endolaryngeal reflux finding score). Body mass index was a predictor of reflux presence in this group of patients with moderate to severe obstructive sleep apnea syndrome. In patients with positive score for endoscopic findings and reflux symptom index (12.3%), there was a trend toward significance for a higher mean apnea-hypopnea index and a higher percentage of sleep time with oxyhemoglobin saturation below 90% (p = 0.05). Conclusion The prevalence of laryngopharyngeal reflux was higher in this group of patients with moderate to severe obstructive sleep apnea syndrome, and the body mass index was a predictor of laryngopharyngeal reflux in these patients. There was a trend toward greater oxyhemoglobin desaturation in patients with a positive score for reflux symptoms index (RSI) and reflux finding score (RFS).

Resumo Introdução A síndrome da apneia obstrutiva do sono e o refluxo laringofaríngeo são doenças com alta prevalência na população em geral. No entanto, ainda não está claro se são doenças com os mesmos fatores de risco presentes nas mesmas populações ou se há alguma relação entre elas. Objetivo Avaliar e determinar a prevalência de refluxo laringofaríngeo em pacientes com síndrome da apneia obstrutiva moderada e acentuada, bem como determinar os fatores preditivos de refluxo nesses pacientes. Método Estudo de coorte histórica com corte transversal de pacientes entre 18 e 70 anos, encaminhados a um ambulatório de Otorrinolaringologia em serviço terciário, com diagnóstico polissonográfico de síndrome da apneia obstrutiva do sono moderada ou acentuada. Foram aplicados o questionário Reflux Sympton Index e o escore de achados endolaríngeos por meio de videolaringoscopia indireta na população estudada, respeitando os critérios de inclusão e exclusão. Resultados Foram avaliados 56 pacientes, dos quais 64,3% apresentaram refluxo laringofaríngeo (Reflux Sympton Index positivo e/ou Reflux Finding Score positivo). O índice de massa corpórea foi fator preditor da presença de refluxo laringofaríngeo nesse grupo de pacientes com síndrome da apneia obstrutiva do sono moderada e acentuada. Nos pacientes cujos Reflux Sympton Index e o escore de achados endolaríngeos foram positivos (12,3%), houve uma tendência à significância para maior índice de apneia e hipopneia e maior porcentagem do tempo de sono com saturação de oxi-hemoglobina abaixo de 90% (p = 0,05). Conclusão A prevalência de refluxo laringofaríngeo foi alta nesse grupo de pacientes com síndrome da apneia obstrutiva do sono moderada e acentuada e o índice de massa corpórea foi fator preditor de refluxo nesses pacientes. Houve uma tendência a maior dessaturacão de oxi-hemoglobina em pacientes com "índice de sintomas de refluxo" e escore de achados endolaríngeos positivos.
