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.

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. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:4071-4077, 2024.

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.

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.

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.

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.

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. LEVEL OF EVIDENCE: 3 Laryngoscope, 134:3981-3988, 2024.

INTRODUCTION: Chatbot Generative Pre-trained Transformer (ChatGPT) is an artificial intelligence-powered language model chatbot able to help otolaryngologists in practice and research. The ability of ChatGPT in generating patient-centered information related to laryngopharyngeal reflux disease (LPRD) was evaluated. METHODS: Twenty-five questions dedicated to definition, clinical presentation, diagnosis, and treatment of LPRD were developed from the Dubai definition and management of LPRD consensus and recent reviews. Questions about the four aforementioned categories were entered into ChatGPT-4. Four board-certified laryngologists evaluated the accuracy of ChatGPT-4 with a 5-point Likert scale. Interrater reliability was evaluated. RESULTS: The mean scores (SD) of ChatGPT-4 answers for definition, clinical presentation, additional examination, and treatments were 4.13 (0.52), 4.50 (0.72), 3.75 (0.61), and 4.18 (0.47), respectively. Experts reported high interrater reliability for sub-scores (ICC = 0.973). The lowest performances of ChatGPT-4 were on answers about the most prevalent LPR signs, the most reliable objective tool for the diagnosis (hypopharyngeal-esophageal multichannel intraluminal impedance-pH monitoring (HEMII-pH)), and the criteria for the diagnosis of LPR using HEMII-pH. CONCLUSION: ChatGPT-4 may provide adequate information on the definition of LPR, differences compared to GERD (gastroesophageal reflux disease), and clinical presentation. Information provided upon extra-laryngeal manifestations and HEMII-pH may need further optimization. Regarding the recent trends identifying increasing patient use of internet sources for self-education, the findings of the present study may help draw attention to ChatGPT-4's accuracy on the topic of LPR.

Objectives: To explore the clinical characteristics of children with adenoid hypertrophy (AH) and laryngopharyngeal reflux (LPR) by detecting the expression of pepsin in adenoids as a standard for AH with LPR. Methods: A total of 190 children who were admitted for surgical treatment due to AH were included in the study. The main clinical symptoms of the patients were recorded, and the degree of adenoid hypertrophy was evaluated. Before the surgery, Reflux Symptom Index (RSI) and Reflux Finding Score (RFS) were used to evaluate the reflux symptoms. After the surgery, pepsin immunohistochemical staining was performed on the adenoid tissue, and according to the staining results, the patients were divided into study group (pepsin staining positive) and control group (pepsin staining negative). SPSS 19.0 software was used for statistical analysis. Quantitative data conforming to normal distribution between the two groups were tested by two-independent sample t test, and quantitative data with skewed distribution were tested by Mann-Whitney U test. Results: The positive rate of pepsin staining in the 190 AH patients was 78.4% (149/190). The study group had higher levels of preoperative symptoms such as erythema and/or congestion of the pharynx(2.1±0.7 vs. 1.8±0.6,t=2.23), vocal cord edema[1.0(0, 1.0) vs. 1.0(0, 1.0), Z=2.00], diffuse laryngeal edema[0(0, 1.0) vs. 0(0, 0), Z=2.48], posterior commissure hypertrophy[(1.4±0.6 vs. 1.1±0.5), t=2.63], and a higher total score on the RFS scale than the control group(6.2±2.7 vs. 5.0±2.6, t=2.47), with statistical differences (P<0.05). The sensitivity and specificity of RFS score in diagnosing AH with LPR were 24.8% and 80.5%, respectively. When RFS>5 was used as the positive threshold, the sensitivity and specificity of RFS score in diagnosing AH with LPR were 61.1% and 58.5%, respectively. There was a statistical difference in the number of positive cases of RFS score between the study group and the control group(91 vs. 17,χ2=5.04,P=0.032). Conclusions: LPR is common in AH children. Children with AH and LPR have specific performance in electronic laryngoscopy, such as erythema with edema in the pharynx, posterior commissure hypertrophy, and vocal cord edema.

OBJECTIVE: To investigate the digestive enzymes and biomarkers in the saliva of patients with laryngopharyngeal reflux (LPR) and asymptomatic individuals. STUDY DESIGN: Prospective controlled study. SETTING: Multicenter study. METHODS: Patients with LPR at the hypopharyngeal-esophageal impedance-pH monitoring (HEMII-pH) and asymptomatic individuals were consecutively recruited from January 2020 to April 2023 from 2 University Hospitals. The saliva of patients (off PPIs) and asymptomatic individuals was collected to measure pH, elastase, bile salts, cholesterol, gastric, and pancreatic lipases. Anxiety, symptoms, and findings were studied through perceived stress scale (PSS), reflux symptom score (RSS), and reflux sign assessment (RSA). RESULTS: Sixty-seven LPR patients and 57 asymptomatic individuals completed the evaluations. LPR patients reported higher PSS, RSS, and RSA than asymptomatic individuals. The mean saliva pH was more alkaline in LPR patients (7.23: 95% confidence interval [CI]: 7.08, 7.38) compared to controls (6.13; 95% CI: 5.95, 6.31; P = .001). The mean concentration of elastase was higher in patients (51.65 µg/mL; 95% CI: 44.47, 58.83 µg/mL) versus asymptomatic individuals (25.18 µg/mL; 95% CI: 21.64, 28.72 µg/mL; P = .001). The saliva cholesterol reported higher concentration in healthy individuals (3.43 mg/dL; 95% CI: 3.21, 3.65 mg/dL) compared to patients (1.16 mg/dL; 95% CI: 1.05, 1.27 mg/dL; P = .001). The saliva pH, and elastase concentration were significantly associated with the baseline RSS, while saliva cholesterol was negatively associated with the severity of RSS and RSA. CONCLUSION: Cholesterol, bile salts, and elastase are biomarkers of LPR and should be considered to develop future non-invasive saliva device for the detection of LPR.

OBJECTIVE: To probe the microbiota composition progressing from healthy individuals to those with laryngopharyngeal reflux disease (LPRD) and subsequently undergoing potassium-competitive acid inhibitor (P-CAB) therapy. STUDY DESIGN: Prospective case-control study. SETTING: Academic Medical Center. METHODS: Forty patients with LPRD and 51 patients without LPRD were recruited. An 8-week P-CAB therapy was initiated (post-T-LPRD), and 39 had return visits. In total, 130 laryngopharyngeal saliva samples were collected and sequenced by targeting the V3-V4 region of the 16S ribosomal RNA (rRNA) gene using an Illumina MiSeq. Amplicon sequence variants (ASVs) and clinical indices were analyzed. RESULTS: Alpha and beta diversities were compared among the non-LPRD, LPRD, and post-T-LPRD groups, and the Observed_ASVs were not significantly different. At the same time, the Shannon and Simpson indices, unweighted Unifrac, weighted Unifrac, and binary Jaccard distance were significantly different between non-LPRD and LPRD groups. In addition, significant differences were found in the abundance of Streptococcus, Prevotella, and Prevotellaceae in the LPRD versus non-LPRD groups, and Neisseria, Leptotrichia, and Allprevotella in the LPRD versus post-T-LPRD groups. The genera model was used to distinguish patients with LPRD from those without, and a better receiver operating characteristic curve was formed after combining the clinical indices of reflux symptom index, reflux finding score, and pepsin, with an area under the curve of 0.960. CONCLUSION: Laryngopharyngeal microbial communities changed after laryngopharyngeal reflux and were modified further after P-CAB treatment, which provides a potential diagnostic value for LPRD, especially when combined with clinical indices.

Laryngopharyngeal reflux disease (LPRD) is a condition characterized by the regurgitation of stomach and duodenal contents into the laryngopharynx, with variable and non-specific symptoms. Therefore, developing an accurate symptom scale for different regions is essential. Notably, the symptoms of "dryness and burning sensation in the laryngopharynx or mouth" are prevalent among the Chinese population but are often omitted from conventional symptom assessment scales, such as the Reflux Symptom Index (RSI) and Reflux Symptom Score-12 (RSS-12) scales. To address this gap, our study incorporated the symptoms into the RSI and RSS-12 scales, developing the RSI-10/RSS-13 scales. Afterward, we assessed the role of the new scale's reliability (Cronbach's α and test-retest reliability), construct validity (confirmatory factor analysis and confirmatory factor analysis), and diagnostic efficiency. Our study encompassed 479 participants (average = 39.5 ± 13.4 years, 242 female) and 91 (average = 34.01 ± 13.50 years, 44 female) completed 24 h MII-pH monitoring. The Cronbach's α values of 0.80 and 0.82 for the RSI-10 and RSS-13 scales, respectively. RSI-10 and RSS-13 exhibited strong test-retest reliability (ICCs = 0.82-0.96) and diagnostic efficacy (AUC = 0.84-0.85). Furthermore, the factor analysis identified the RSS-13 and its three sub-scales (ear-nose-throat, digestive tract, respiratory tract) exhibited good to excellent structural validity (χ2/df = 1.95, P < 0.01; CFI = 0.95, RMSEA = 0.06, SRMR = 0.05). The AUC optimal thresholds for the RSI-10 and RSS-13 in the Chinese population were 13 and 36, respectively. Besides, the inclusion of the new item significantly improved the diagnostic efficiency of the RSI scale (P = 0.04), suggesting that RSI-10 holds promise as a more effective screening tool for LPRD, and global validation is needed to demonstrate the impact of this new symptom on the diagnosis of LPRD.

Objective: The aim of this study was to compare the efficacy of voice therapy combined with standard anti-reflux therapy in reducing symptoms and signs of laryngopharyngeal reflux (LPR). Methods: A randomised clinical trial was conducted. Fifty-two patients with LPR diagnosed by 24 h multichannel intraluminal impedance-pH monitoring were randomly allocated in two groups: medical treatment (MT) and medical plus voice therapy (VT). Clinical symptoms and laryngeal signs were assessed at baseline and after 3 months of treatment with the Reflux Symptom Index (RSI), Reflux Finding Score (RFS), Voice Handicap Index (VHI) and GRBAS scales. Results: Groups had similar scores at baseline. At 3-month follow-up, a significant decrease in RSI and RFS total scores were found in both groups although it appeared to be more robust in the VT group. G and R scores of the GRBAS scale significantly improved after treatment in both groups, with better results in the VT group. The VHI total score at 3 months improved more in the VT group (VHI delta 9.54) than in the MT group (VHI delta 5.38) (p < 0.001). Conclusions: The addition of voice therapy to medications and diet appears to be more effective in improving treatment outcomes in subjects with LPR. Voice therapy warrants consideration in addition to medication and diet when treating patients with LPR.

BACKGROUND: Laryngopharyngeal reflux (LPR) refers to the backflow of acidic stomach content into the larynx, pharynx, and upper aerodigestive tract. The diagnosis of LPR is based on the patient's history and findings of the laryngoscopy associated with LPR. Other possible manifestations consistent with LPR symptoms include laryngeal cancer, vocal fold granulomas, Reinke's space edema, and vocal polyps. In this study, we compared the characteristics of patients with LPR symptoms and incidental laryngeal findings (ILF) in the laryngoscopic evaluation to those without ILF (WILF). OBJECTIVES: Determine the characteristics of LPR-symptomatic patients with ILF versus WILF. METHODS: In this retrospective study, we examined 160 medical charts from patients referred to the otolaryngology clinic at Galilee Medical Center for LPR evaluation 2016-2018. The reflux symptoms index (RSI), reflux finding score (RFS), and demographics of the patient were collected. All patients with a positive RSI score for LPR (RSI > 9) were included, and the profiles of patients with versus without ILF on laryngoscopy examination were compared. RESULTS: Of the 160 patients, 20 (12.5%) had ILF during laryngoscopy. Most had vocal cord findings such as leukoplakia (20%), polyps (15%), and nodules (20%). Hoarseness, throat clearing, swallowing difficulty, breathing difficulties, and total RSI score were significantly higher in patients with ILF. CONCLUSIONS: Evaluation of LPR symptoms may provide otolaryngologists with a tool to identify patients with other findings on fiberoptic laryngoscopy. A laryngoscopic examination should be part of the examination of every patient with LPR to enable diagnosis of incidental findings.

Esophagogastroduodenoscopy (EGD) is recommended in patients with typical gastroesophageal reflux disease (GERD) symptoms (heartburn, regurgitation, chest pain) in the setting of proton pump inhibitor (PPI) nonresponse. EGD evaluates for erosive disease, assesses antireflux barrier integrity, excludes non-GERD conditions, and, in the absence of erosive findings, is followed by reflux testing.1,2 The diagnostic utility of EGD is less clear in the evaluation for laryngopharyngeal reflux (LPR), and the current reference standard is ambulatory reflux monitoring.1,3,4 This study of patients referred for evaluation of chronic laryngeal symptoms had the following aims: (1) to characterize endoscopic findings, (2) to discern whether findings differed between patients with or without concomitant esophageal reflux symptoms, and (3) to measure the association between endoscopic findings and objective GERD on ambulatory reflux monitoring.

Objective: To investigate the risk factors for the occurrence of laryngopharyngeal reflux disease in the aged, and to analyze the characteristics of patients with pneumonia. Methods: Patients who underwent 24-hour laryngopharyngeal pH monitoring from June 2020 to July 2022 and the positive patients of those who underwent 24-hour esophageal pH monitoring from March 2017 to July 2022 at the Second Medical Center of the PLA General Hospital were enrolled retrospectively. Positive results of 24-hour laryngopharyngeal reflux monitoring were in the laryngopharyngeal reflux group, and the negative results were in the non-laryngopharyngeal reflux group. Patients with pneumonia and simple gastroesophageal reflux disease were in the esophageal reflux pneumonia group, and patients with pneumonia and simple laryngopharyngeal reflux disease were in the laryngopharyngeal reflux pneumonia group. Patients' basic data, co-morbidities, drug use and relevant examination and test results were collected. Multivariate logistic regression analysis was used to analyze the risk factors of laryngopharyngeal reflux disease in the aged and its relationship with pneumonia. Results: A total of 80 patients with 24-hour laryngopharyngeal pH monitoring were enrolled finally, including 34 cases, all male, aged (73±12) years, in the laryngopharyngeal reflux group, and 46 cases [44 males, 2 females, aged (78±11) years] in the non-laryngopharyngeal reflux group. Multivariate logistic regression analysis showed that the risk factors of laryngopharyngeal reflux disease in the aged included age ≤70 years (OR=13.07, 95%CI: 2.53-67.68), body mass index (BMI) (OR=1.37, each additional 1 kg/m2, 95%CI: 1.03-1.83), use of antipsychotic drugs (OR=8.00, 95%CI: 1.40-45.73) and calcium channel blockers (OR=5.27, 95%CI: 1.13-24.53) (all P<0.05). The protective factors of the laryngopharyngeal reflux disease in the aged included antacids (OR=0.19, 95%CI: 0.04-0.90, P=0.035). The incidence of pneumonia was higher in the laryngopharyngeal reflux group compared with the non-laryngopharyngeal reflux group [44.1% (15/34) vs 21.7% (10/46), P=0.033]. The esophageal reflux pneumonia group included 32 cases [31 males and 1 females, aged (84±12) years]. The laryngopharyngeal reflux pneumonia group included 15 cases [ 15 males, aged (79±11) years]. Compared to the patients in the laryngopharyngeal reflux pneumonia group, the patients in the esophageal reflux pneumonia group had a longer course of antibiotics [(27.7±27.0) vs (14.6±13.9) days, P=0.034], a higher frequency of seizure frequency [(4.3±3.0) vs (1.8±1.5) times/year, P<0.001] and a higher maximal body temperature [(38.2±0.9) vs (37.6±1.1) â, P=0.037]. Conclusions: The risk factors of laryngopharyngeal reflux disease in the aged included age ≤70 years, higher BMI, use of antipsychotic drugs and calcium channel blockers. The incidence of pneumonia in laryngopharyngeal reflux disease is higher, but the condition of pneumonia is milder.

BACKGROUND: Laryngopharyngeal reflux has classically referred to gastroesophageal reflux leading to chronic laryngeal symptoms such as throat clearing, dysphonia, cough, globus sensation, sore throat or mucus in the throat. Current lack of clear diagnostic criteria significantly impairs practitioners' ability to identify and manage laryngopharyngeal reflux. AIMS: To discuss current evidence-based diagnostic and management strategies in patients with laryngopharyngeal reflux. METHODS: We selected studies primarily based on current guidelines for gastroesophageal reflux disease and laryngopharyngeal reflux, and through PubMed searches. RESULTS: We assess the current diagnostic modalities that can be used to determine if laryngopharyngeal reflux is the cause of a patient's laryngeal symptoms, as well as review some of the common treatments that have been used for these patients. In addition, we note that the lack of a clear diagnostic gold-standard, as well as specific diagnostic criteria, significantly limit clinicians' ability to determine adequate therapies for these patients. Finally, we identify areas of future research that are needed to better manage these patients. CONCLUSIONS: Patients with chronic laryngeal symptoms are complex due to the heterogenous nature of symptom pathology, inconsistent definitions and variable response to therapies. Further outcomes data are critically needed to help elucidate ideal diagnostic workup and therapeutic management for these challenging patients.
