The Tibetan Formula Cong zhi 6 in the ORL (ENT) Practice: Experiences with Laryngopharyngeal Reflux.

BACKGROUND: Laryngopharyngeal reflux (LPR) is a frequent condition; in European countries, the prevalence can be estimated as 10-30% of the general population. Treatment includes lifestyle measures and highly dosed proton pump inhibitors (PPIs) over at least 4 weeks. However, PPIs are not unproblematic due to their potential side effects and the known phenomenon of rebound acid hypersecretion. Cong zhi 6 is a multi-herbal Tibetan formula additionally containing calcium carbonate and is available in several European countries as a food supplement Padma Aciben/Padma AciTib. CASE REPORT: Ten patients with LPR took Cong zhi 6. The course of the complaints was documented, and the data were retrospectively analysed. Clinical symptoms as assessed with the Reflux Symptom Index (RSI) questionnaire and the findings in laryngoscopy with the Reflux Finding Score (RFS) both showed marked improvement of several symptoms. The number of patients with pathological LPR sum score was significantly reduced from 8 to 2 patients and from 10 to 1 patient in RSI and RFS, respectively. The mean sum scores were reduced from 18.1 to 8.4 (RSI) and from 12.9 to 4.4 (RFS), respectively. Also, other gastrointestinal symptoms, such as abdominal pain, bloating, feeling of fullness, and nausea, which are usually associated with functional dyspepsia and irritable bowel syndrome, were markedly improved (reduction of mean score of the 3 most frequent symptoms by 77-87%). CONCLUSION: Standard medical treatment for LPR consists in high dosed PPI for at least 4 weeks, which is known for several side effects and does not treat reliable the nonacid component of LPR of pepsin or other gastric enzymes. Therefore, other medical treatment options are urgently needed. The promising data of this case series suggest that the Tibetan herbal formula Cong zhi 6 may be a treatment option in LPR and related gastrointestinal symptoms and warrant further research.Der laryngopharyngeale Reflux (LPR) ist eine häufige Erkrankung. In europäischen Ländern wird die Prävalenz in der Gesamtbevölkerung auf 10­30% geschätzt. Die Behandlung beinhaltet Ernährungs- und Verhaltensänderung sowie die Gabe hochdosierter Protonen-Pumpen-Hemmer (PPI) über mindestens 4 Wochen. PPI sind jedoch aufgrund ihrer hohen potenziellen Nebenwirkungen und des bekannten Rebound-Phänomens der sauren Magensafthypersekretion nicht unproblematisch. Cong zhi 6 ist eine tibetische Rezeptur aus einem Vielpflanzengemisch sowie zusätzlich Calciumcarbonat und ist in einigen europäischen Ländern als Nahrungsergänzungsmittel Padma Aciben/Padma AciTib erhältlich.Zehn Patienten mit laryngo-pharyngealem Reflux (LPR) nahmen Cong zhi 6 ein. Der Beschwerdeverlauf wurde dokumentiert und die Daten retrospektiv analysiert. Die klinischen Symptome, die mithilfe des Reflux Symptom Index (RSI) Fragebogens erfasst wurden und die mittels des Reflux Finding Score (RFS) beurteilten laryngoskopischen Befunde zeigten beide eine deutliche Verbesserung verschiedener Symptome. Die Zahl der Patienten mit pathologischen LPR-Summenscore reduzierte sich signifikant, im RSI von 8 auf 2 und im RFS von 10 auf 1 Patienten. Der mittlere Summenwert sank von 18.1 auf 8.4 (RSI) und von 12.9 auf 4.4 (RFS). Des Weiteren zeigte sich auch bei anderen gastrointestinalen Beschwerden, wie Bauchschmerzen, Blähungen, Völlegefühl und Übelkeit, die normalerweise mit funktioneller Dyspepsie oder Reizdarm zusammenhängen, eine deutliche Verbesserung (durchschnittliche Verringerung des Scores der drei häufigsten Symptome um 77­87%).Die medikamentöse Standardbehandlung bei LPR besteht aus der hochdosierten PPI-Gabe über mindestens 4 Wochen, die jedoch für verschiedene Nebenwirkungen bekannt ist und die nicht-saure Komponente von LPR, wie Pepsin oder andere digestive Enzyme, nicht mitbehandelt. Daher sind andere medikamentöse Behandlungsmöglichkeiten dringend erforderlich. Die vielversprechenden Daten dieser Fallserie deuten darauf hin, dass die tibetische Pflanzenrezeptur Cong zhi 6 eine Behandlungsoption bei LPR sowie deren gastrointestinalen Symptome darstellt und rechtfertigen weitere Studien.

Transcutaneous electrical acupoint stimulation for suspected laryngopharyngeal reflux disease.

PURPOSE: To determine the efficacy of transcutaneous electrical acupoint stimulation (TEAS) combined with proton pump inhibitor (PPI) therapy on symptoms and signs of patients with suspected laryngopharyngeal reflux disease (LPRD). METHODS: This was a prospective randomized controlled study. Seventy patients with reflux symptom index (RSI) > 13 and reflux finding score (RFS) > 7 were recruited and received PPI alone (control group) or TEAS combined with PPI (experimental group) for 12 weeks. Patients in the experimental group received TEAS at Tiantu (RN22), Renying (ST9), and Neiguan (PC6) once a day, five times a week. RSI, RFS, throat pain visual analog score (VAS), and LPR-health-related quality-of-life (LPR-HRQL) scores were evaluated at baseline and after 4 and 12 weeks. RESULTS: The decreases in total RSI and RFS, along with several subscores, were significantly higher in the experimental group than in the control group after 12 weeks (P < 0.05). The throat pain VAS and LPR-HRQL scores decreased significantly at 4 and 12 weeks after treatment in both groups, with significant differences between the groups (P < 0.001). No severe adverse events occurred, and the rates of adverse events were similar between the two groups. CONCLUSION: Compared with PPI alone, TEAS combined with PPI showed a significantly greater improvement in symptoms, signs, and quality of life in the treatment of LPRD without increasing the occurrence of adverse effects. Therefore, TEAS could serve as a useful and safe treatment method for LPRD. TRIAL REGISTRATION: Chinese Clinical Trial Registry, ChiCTR2100046755.

[The preliminary application of vonoprazan fumarate on laryngopharyngeal reflux disease].

Objective: To evaluate the clinical effect of vonoprazan fumarate on laryngopharyngeal reflux disease (LPRD). Methods: The clinical data of 89 patients from June 2020 to January 2022, including 45 males and 44 females, aged 18-77 (45.54±13.53) years old, were retrospectively analyzed. All the patients were diagnosed as suspected LPRD according to reflux symptom index (RSI) and reflux finding score (RFS). Patients of the Vonoprazan Fumarate group were prescribed Vonoprazan Fumarate orally (20 mg, qd) for 8 weeks.Patients of the Esomeprazole group were prescribed Esomeprazole orally (20 mg, bid) for 8 weeks. RSI and RFS of all the patients before and after treatment were compared. SPSS 18.0 was used for statistics analysis. Results: Before treatment, gender, age, RSI and RFS of the two groups had no obvious differences. After treatment, RSI and RFS in both groups were alleviated significantly. In the vonorazan fumarate group, the RSI before treatment was 12.62±7.18, and after treatment was 4.74±3.87(t=6.91, P<0.001), the RFS was 10.78±2.29 before treatment and 8.24±2.45 after treatment (t=7.06, P<0.001). While in the esomeprazole group, the RSI was 13.27±6.95 before treatment and 6.02±4.28 after treatment (t=7.50, P<0.001), the RFS was 10.59±3.14 before treatment and 8.14±3.30 after treatment (t=5.41, P<0.001). There was no significant difference in the effective rate between the two groups (86.7% in the vonoprazan fumarate group and 77.3% in the esomeprazole group, χ2=1.443, P=0.486). Conclusion: Vonoprazan fumarate could effectively alleviate the symptoms and signs of LPRD patients. The effect of vonoprazan fumarate on LPRD is not inferior to Esomeprazole. It can be used as a supplement to PPI.

Trial of transcutaneous electrical acupoint stimulation in laryngopharyngeal reflux disease: study protocol for a randomized controlled trial.

BACKGROUND: Patients with persistent globus sensation, throat clearing, chronic cough, hoarseness, and other throat symptoms account for a large proportion of patients in ears, nose, and throat clinics. Laryngopharyngeal reflux disease (LPRD) is increasingly valued by otolaryngologists. Transcutaneous electrical acupoint stimulation (TEAS) is possibly a new method for the treatment of LPRD. This trial aims to determine whether TEAS combined with proton pump inhibitor (PPI) is better than PPI alone in the treatment of LPRD. METHODS: This prospective randomized controlled trial will be implemented in a tertiary hospital in China. Seventy patients diagnosed with LPRD will be randomly assigned to the TEAS + PPI group (intervention group) or PPI group (control group), at a ratio of 1:1. In addition to using PPI, the intervention group will receive TEAS at four groups of acupoints, and each group will be treated for 15 min, once for 60 min, five times a week, for 12 weeks, 60 times. The main outcome will be changes in the Reflux Symptom Index scores at 4, 12, and 24 weeks after treatment. The secondary outcomes will include changes in the reflux finding score, Laryngopharyngeal Reflux-Health-related Quality of Life score, and throat pain visual analog scale score. DISCUSSION: This trial will explore the feasibility of TEAS combined with PPI for the treatment of LPRD and provide potential evidence for its effectiveness and safety. The results of this study will be published in a peer-reviewed journal. TRIAL REGISTRATION: Chinese Clinical Trial Registry ChiCTR2100046755 . Registered on May 28, 2021.

Response of Laryngopharyngeal Symptoms to Transoral Incisionless Fundoplication in Patients with Refractory Proven Gastroesophageal Reflux.

OBJECTIVE: Patients with laryngopharyngeal reflux (LPR) symptoms may not respond to proton pump inhibitors (PPI) if they have an alternative laryngeal diagnosis or high-volume reflux. Transoral incisionless fundoplication (TIF) or TIF with concomitant hiatal hernia repair (cTIF) are effective in decreasing symptoms of gastroesophageal reflux disease (GERD) but are not well studied in patients with LPR symptoms. This prospective multicenter study assessed the patient-reported and clinical outcomes after TIF/cTIF in patients with LPR symptoms and proven GERD. METHODS: Patients with refractory LPR symptoms (reflux symptom index [RSI] > 13) and with erosive esophagitis, Barrett's esophagus, and/or pathologic acid reflux by distal esophageal pH testing were evaluated before and after a minimum of 6 months after TIF/cTIF. The primary outcome was normalization of RSI. Secondary outcomes were >50% improvement in GERD-Health-Related Quality of Life (GERD-HRQL), normalization of esophageal acid exposure time, discontinuation of PPI, and patient satisfaction. RESULTS: Forty-nine patients had TIF (n = 26) or cTIF (n = 23) with at least 6 months follow-up. Mean pre- and post TIF/cTIF RSI were 23.6 and 5.9 (mean difference: 17.7, P < .001). Post TIF/cTIF, 90% of patients had improved GERD-HQRL score, 85% normalized RSI, 75% normalized esophageal acid exposure time, and 80% discontinued PPI. No serious procedure-related adverse events occurred. Patient satisfaction was 4% prior to TIF/cTIF and 73% after TIF/cTIF (P < .001). CONCLUSION: In patients with objective evidence of GERD, TIF, or cTIF are safe and effective in controlling LPR symptoms as measured by normalization of RSI and improvement in patient satisfaction after TIF/cTIF. LEVEL OF EVIDENCE: Level 4.

A new diagnostic paradigm for laryngopharyngeal reflux disease: correlation of impedance-pH monitoring and digital reflux scintigraphy results.

PURPOSE: No gold-standard investigation exists for laryngopharyngeal reflux (LPR). Multichannel intraluminal impedance (MII)-pH testing has uncertain utility in LPR. Meanwhile, reflux scintigraphy allows immediate and delayed visualisation of tracer reflux in the esophagus, pharynx, and lungs. The present study aimed to correlate MII-pH and scintigraphic reflux results in patients with primary LPR. METHODS: Consecutive patients with LPR underwent MII-pH and scintigraphic reflux studies. Abnormal values for MII-pH results were defined from existing literature. MII-pH and scintigraphic data were correlated. RESULTS: 105 patients with LPR [31 males (29.5%), median age 60 years (range 20-87)] were studied. Immediate scintigraphic reflux was seen in the pharynx in 94 (90.4%), and in the proximal esophagus in 94 (90.4%). Delayed scintigraphic contamination of the pharynx was seen in 101 patients (96.2%) and in the lungs of 56 patients (53.3%). For MII-pH, abnormally frequent reflux was seen in the distal esophagus in 12.4%, proximal esophagus in 25.7%, and in the pharynx in 82.9%. Patients with poor scintigraphic clearance had higher Demeester scores (p = 0.043), more proximal reflux episodes (p = 0.046), more distal acid reflux episodes (p = 0.023), and more prolonged bolus clearance times (p = 0.002). CONCLUSION: Reflux scintigraphy has a high yield in LPR patients. Scintigraphic time-activity curves correlated with validated MII-pH results. A high rate of pulmonary microaspiration was found in LPR patients. This study demonstrated a high level of pharyngeal contamination by scintigraphy and MII-pH, which supports the use of digital reflux scintigraphy in diagnosing LPR.

Alternatives to Acid Suppression Treatment for Laryngopharyngeal Reflux.

OBJECTIVE: Laryngopharyngeal reflux (LPR) and associated symptoms can be refractory to treatment with acid suppressing medication. We investigated the role and evidence for complementary and alternative medicine (CAM) for LPR in this systematic review. REVIEW METHODS: Complementary and alternative treatment was defined in this systematic review as any non-acid suppressing medication, treatment, or therapy. A literature search was performed by two authors in consultation with a medical librarian using controlled vocabulary for "complementary and alternative medicine" and "laryngopharyngeal reflux" in the databases PubMed and EMBASE, with supplemental searches with Google Scholar. RESULTS: Twenty articles were included in this review for the modalities: alginate, diet modification, prokinetics, respiratory retraining, voice therapy, rikkunshito (RKT), hypnotherapy, and sleep positioning. The studies were analyzed for bias based on the Cochrane criteria for RCTs and Methodological Index for non-RCT (MINORS) criteria for all other studies. For each modality a level of evidence was assigned to the current body of evidence using the GRADE approach. CONCLUSION: There is mixed evidence with a high degree of bias and heterogeneity between studies for the modalities presented in the paper. Based on this review, an anti-reflux diet is recommended for all patients and there is some low-quality evidence to support alkaline water. For patients with predominant vocal symptoms there is evidence that supports voice therapy. There is insufficient evidence to recommend prokinetics at this time. For patients with predominant globus symptoms, alginate, RKT, and relaxation strategies may be used in conjunction with acid suppressing medications for symptom relief.

[Clinical study of laryngopharyngeal reflux treated with acupuncture on the base of theory of the ascending and the descending of qi].

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 qi. 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 qi 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 (P<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 (P<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 (P<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 qi combined with western medication contribute to the recovery of gastrointestinal function, effectively control the laryngopharyngeal symptoms and physical signs. The therapeutic effect of this comprehensive therapy is better than the simple treatment with western medication.

Promotion of Regular Oesophageal Motility to Prevent Regurgitation and Enhance Nutrition Intake in Long-Stay ICU Patients. A Multicenter, Phase II, Sham-Controlled, Randomized Trial: The PROPEL Study.

OBJECTIVES: To evaluate the effect of esophageal stimulation on nutritional adequacy in critically ill patients at risk for enteral feeding intolerance. DESIGN: A multicenter randomized sham-controlled clinical trial. SETTING: Twelve ICUs in Canada. PATIENTS: We included mechanically ventilated ICU patients who were given moderate-to-high doses of opioids and expected to remain alive and ventilated for an additional 48 hours and who were receiving enteral nutrition or expected to start imminently. INTERVENTIONS: Patients were randomly assigned 1:1 to esophageal stimulation via an esophageal stimulating catheter (E-Motion Tube; E-Motion Medical, Tel Aviv, Israel) or sham treatment. All patients were fed via these catheters using a standardized feeding protocol. MEASUREMENTS AND MAIN RESULTS: The co-primary outcomes were proportion of caloric and protein prescription received enterally over the initial 7 days following randomization. Among 159 patients randomized, the modified intention-to-treat analysis included 155 patients: 73 patients in the active treatment group and 82 in the sham treatment group. Over the 7-day study period, the percent of prescribed caloric intake (± SE) received by the enteral route was 64% ± 2 in the active group and 65% ± 2 in sham patients for calories (difference, -1; 95% CI, -8 to 6; p = 0.74). For protein, it was 57% ± 3 in the active group and 60% ± 3 in the sham group (difference, -3; 95% CI, -10 to 3; p = 0.30). Compared to the sham group, there were more serious adverse events reported in the active treatment group (13 vs 6; p = 0.053). Clinically important arrhythmias were detected by Holter monitoring in 36 out of 70 (51%) in the active group versus 22 out of 76 (29%) in the sham group (p = 0.006). CONCLUSIONS: Esophageal stimulation via a special feeding catheter did not improve nutritional adequacy and was associated with increase risk of harm in critically ill patients.

Trigger Reduction Prior to Systemic Drugs for Neurogenic Chronic Cough.

OBJECTIVE/HYPOTHESIS: Neurogenic chronic cough typically presents as a postviral chronic cough, often with paroxysms of coughing preceded by a tickle sensation with multiple triggers and often recalcitrant to multiple treatments for reflux disease, sinus disease, and asthma. Current treatment uses neuromodulating agents with moderate success. Post nasal drainage and laryngopharyngeal reflux can be triggers in the setting of laryngopharyngeal hypersensitivity. Treatment will focus on trigger reduction using nasal toilet and a dietary regimen for laryngopharyngeal reflux. STUDY DESIGN: Systematic review of retrospective cohort studies METHODS: One-year retrospective review of new patients with cough (R05.0) excluding asthma, proton pump inhibitor response, and sinus or pulmonary disease. Cough severity index (CSI) and reflux symptom index (RSI) were evaluated initially and 6 weeks after trigger-reduction treatment using nasal saline irrigation, nasal steroids, nasal antihistamines, and a plant-based diet with alkaline water. RESULTS: Of 119 patients, 29 met the criteria. Using the six-point reduction (improvement) in RSI as an accepted response, 20 of 29 patients (68.9%, P = .0014) experienced a clinical response. Using reduction in RSI and CSI as a continuous variable to assess response, patients experienced a 10 (95% confidence interval [CI]: 6.75-13.2) and 10.9 (95% CI: 7.4-14.3) mean point reduction, respectively. The mean percent reduction in RSI following 6 weeks of treatment was 54.7% (95% CI: 41.5-68.0; P = .0001). These patients experienced a 59.8% (95% CI: 43.4-76.2; P = .0001) reduction in CSI. CONCLUSIONS: A trigger-reduction approach using nasal toilet and a plant-based diet in patients with neurogenic chronic cough prior to the initiation of systemic neuromodulating medications should be considered. LEVEL OF EVIDENCE: 4 Laryngoscope, 129:198-202, 2019.

Gaviscon® Advance alone versus co-prescription of Gaviscon® Advance and proton pump inhibitors in the treatment of laryngopharyngeal reflux.

OBJECTIVES: Management of laryngopharyngeal reflux (LPR) typically comprises alginates and proton pump inhibitors (PPIs) alone or in combination, yet evidence to support any particular treatment regimen is lacking. We sought to evaluate the efficacy of Gaviscon® Advance alone versus co-prescription with a PPI in treating LPR. METHODS: One hundred consecutive LPR patients with a reflux symptom index (RSI) score > 10 attending our joint voice clinic (JVC) were studied prospectively. All were treated with Gaviscon® Advance four times daily. If patients had been started on a PPI prior to their JVC attendance, this was optimised to a twice-daily dosing regimen and continued. RSI scores were recorded at first attendance and 3 months post-treatment via postal questionnaire. Scores were analysed using t tests and Levene's test for equality of variances. RESULTS: Follow-up RSI scores were returned by 72 patients, 39 of whom were treated with Gaviscon® Advance only (group A) and 33 with Gaviscon® Advance + PPI (group B). Mean pre-treatment RSI scores were similar between groups [group A: 19.2, 95% confidence interval (CI) ± 2.4; group B: 21.3, 95% CI ± 3.2 (p = 0.65)]. No significant differences were observed with respect to 3-month post-treatment RSI scores [group A: 9.9, 95% CI ± 2.8; group B: 12.6, 95% CI ± 4.2 (p = 0.82)] and change in RSI scores [group A: 9.3, 95% CI ± 3.0; group B: 8.7, 95% CI ± 2.9 [p = 0.75]). CONCLUSIONS: Gaviscon® Advance alone is effective in treating symptoms of LPR, while co-prescription with a high-dose PPI offers no additional benefit.

Resolution of esophageal dysmotility following treatment of nasal disease in a dog.

A 2-year-old Rottweiler dog was evaluated for cough, regurgitation, and nasal discharge, and was subsequently diagnosed with sinonasal aspergillosis and secondary esophageal disease. Following treatment of sinonasal aspergillosis, all clinical signs resolved. To the authors' knowledge, this is the first report of resolution of esophageal dysfunction following treatment of sinonasal aspergillosis.

Focus on gastroesophageal reflux (GER) and laryngopharyngeal reflux (LPR): new pragmatic insights in clinical practice.

Introduction: Gastroesophageal reflux (GER) is a common disease usually limited to the oesophagus. Laryngopharyngeal reflux (LPR) is an inflammatory reaction of the mucosa of pharynx, larynx, and other associated upper respiratory organs, caused by a reflux of stomach contents outside the oesophagus. LPR is considered to be a relatively new clinical entity with a vast number of clinical manifestations which are treated sometimes empirically and without a correct diagnosis. However, there is disagreement between specialists about its definition and management: gastroenterologists consider LPR to be a substantially rare manifestation of gastroesophageal reflux disease (GERD), whereas otolaryngologists believe that LPR is an independent, but common in their practice, disorder. Patients suffering from LPR firstly consult their general practitioners, but a multidisciplinary approach may be fruitful to define a unified strategy based on specific medications and behavioural changes. The present Supplement would review the topic, considering LPR and GER characteristics, pathophysiology, diagnostic work-up, and new therapeutic strategies also comparing different specialist points of view and patient populations. In particular, new insights derive from an interesting gel compound, containing magnesium alginate and E-Gastryal® (hyaluronic acid, hydrolysed keratin, Tara gum, and Xantana gum). In particular, two very large Italian surveys were conducted in real-world setting, such as outpatient clinics. The most relevant outcomes are presented and discussed in the current Issue. Actually, laryngopharyngeal reflux (LPR) is considered an extraesophageal manifestation of the gastroesophageal reflux disease (GERD). Both GERD and its extraesophageal manifestation are very common in clinical practice. Both disorders have a relevant burden for the society: about this topic most of pharmaco-economic studies were conducted in the United States. In population-based studies, 19.8% of North Americans complain of typical symptoms of GERD (heartburn and regurgitation) at least weekly (1). Also in the late 1990s, GERD accounted for $9.3 to $12.1 billion in direct annual healthcare costs in the United States, higher than any other digestive disease. As a result, acid-suppressive agents were the leading pharmaceutical expenditure in the United States. The prevalence of GERD in the primary care setting becomes even more evident when one considers that, in the United States, 4.6 million office encounters annually are primarily for GERD, whereas 9.1 million encounters include GERD in the top 3 diagnoses for the encounter. GERD is also the most frequently first-listed gastrointestinal diagnosis in ambulatory care visits (2, 3) Extraesophageal manifestations of reflux, including LPR, asthma, and chronic cough, have been estimated to cost $5438 per patient in direct medical expenses in the first year after presentation and $13,700 for 5 years.

Síndrome de rumiación: dificultades diagnósticas y terapéuticas de un proceso no tan infrecuente / Rumination syndrome: Diagnostic and therapeutic difficulties of a not so uncommon disorder

Introducción: El Síndrome de rumiación es un trastorno gastrointestinal funcional poco común. De diagnóstico difícil, por el desconocimiento del mismo dentro del colectivo médico, acaba conllevando la realización de múltiples pruebas complementarias, la aplicación de diferentes tratamientos, y diagnósticos tardíos o erróneos, en la mayoría de los casos. Su tratamiento es difícil y complejo dada su naturaleza multifactorial. El objetivo de este estudio es presentar nuestra casuística analizando sus datos clínicos, diagnósticos y terapéuticos. Pacientes y método: Estudio descriptivo y retrospectivo de todos los casos diagnosticados entre enero del 2010 y mayo del 2016, controlados en las unidades de Gastroenterología Pediátrica del Consorci Sanitari de Terrassa y del Hospital Materno-Infantil Vall d'Hebron. Resultados: Se analizó a un total de 12 pacientes. Una media de edad al inicio de los síntomas de 9 anos y un mes, con un tiempo medio de evolución antes de llegar al diagnóstico de 2 años y 3 meses, y una media de pruebas complementarias realizadas hasta del diagnóstico de 8,1. En 10 de los 12 pacientes se había probado, antes del diagnóstico de rumiación, algún tipo de tratamiento que resultó ineficaz en todos los casos. Como novedad terapéutica, 10 de nuestros casos se sometieron a un tratamiento experimental de biofeedback. Conclusiones: Debido al conocimiento limitado de esta entidad, entre nuestros profesionales, en cuanto a su presentación clínica, diagnóstico y tratamiento, estos pacientes son frecuentemente mal diagnosticados y, a menudo, se ven sometidos a pruebas complementarias y tratamientos evitables, invasivos y costosos (AU)

Introduction: Rumination syndrome is an uncommon gastrointestinal functional disorder that may be difficult to diagnose, as not many physicians are aware of this condition. In many cases, patients undergo numerous tests and are prescribed several treatments based on erroneous diagnoses. When the correct diagnosis is eventually made, therapy for the syndrome can be difficult and complex because of its multifactorial nature. The aim of this study was to present our experience with this condition, by presenting an analysis of the clinical, diagnostic, and therapeutic data of our patients. Patients and method: A prospective and retrospective study was conducted on all cases of rumination syndrome diagnosed between January 2010 and May 2016 in patients attending the Paediatric Gastroenterology Departments of two hospitals: Consorci Sanitari de Terrassa and Hospital Materno-Infantil Vall d’Hebron (Barcelona, Spain). Results: The analysis included 12 patients, with a mean age at the onset of symptoms of 9 years and 1 month, and the mean time period to make the diagnosis was 2 years and 3 months. A mean of 8.1 complementary tests were carried out before establishing the diagnosis. In 10 of the 12 patients, some type of treatment had been given before the diagnosis of rumination syndrome, but was unsuccessful in all cases. Ten of our patients underwent the novel, experimental biofeedback therapy. Conclusions: Due to the limited knowledge of this condition among attending professionals in terms of the clinical presentation, diagnosis, and treatment, patients with rumination syndrome are often misdiagnosed and undergo numerous avoidable complementary tests, and invasive, costly treatments (AU)

A Comparison of Alkaline Water and Mediterranean Diet vs Proton Pump Inhibition for Treatment of Laryngopharyngeal Reflux.

Importance: Laryngopharyngeal reflux (LPR) is a common disorder with protean manifestations in the head and neck. In this retrospective study, we report the efficacy of a wholly dietary approach using alkaline water, a plant-based, Mediterranean-style diet, and standard reflux precautions compared with that of the traditional treatment approach of proton pump inhibition (PPI) and standard reflux precautions. Objective: To determine whether treatment with a diet-based approach with standard reflux precautions alone can improve symptoms of LPR compared with treatment with PPI and standard reflux precautions. Design, Setting, and Participants: This was a retrospective medical chart review of 2 treatment cohorts. From 2010 to 2012, 85 patients with LPR that were treated with PPI and standard reflux precautions (PS) were identified. From 2013 to 2015, 99 patients treated with alkaline water (pH >8.0), 90% plant-based, Mediterranean-style diet, and standard reflux precautions (AMS) were identified. The outcome was based on change in Reflux Symptom Index (RSI). Main Outcomes and Measures: Recorded change in the RSI after 6 weeks of treatment. Results: Of the 184 patients identified in the PS and AMS cohorts, the median age of participants in each cohort was 60 years (95% CI, 18-82) and 57 years (95% CI, 18-93), respectively (47 [56.3%] and 61 [61.7%] were women, respectively). The percentage of patients achieving a clinically meaningful (≥6 points) reduction in RSI was 54.1% in PS-treated patients and 62.6% in AMS-treated patients (difference between the groups, 8.05; 95% CI, -5.74 to 22.76). The mean reduction in RSI was 27.2% for the PS group and 39.8% in the AMS group (difference, 12.10; 95% CI, 1.53 to 22.68). Conclusions and Relevance: Our data suggest that the effect of PPI on the RSI based on proportion reaching a 6-point reduction in RSI is not significantly better than that of alkaline water, a plant-based, Mediterranean-style diet, and standard reflux precautions, although the difference in the 2 treatments could be clinically meaningful in favor of the dietary approach. The percent reduction in RSI was significantly greater with the dietary approach. Because the relationship between percent change and response to treatment has not been studied, the clinical significance of this difference requires further study. Nevertheless, this study suggests that a plant-based diet and alkaline water should be considered in the treatment of LPR. This approach may effectively improve symptoms and could avoid the costs and adverse effects of pharmacological intervention as well as afford the additional health benefits associated with a healthy, plant-based diet.

Rethinking the laryngopharyngeal reflux treatment algorithm: Evaluating an alternate empiric dosing regimen and considering up-front, pH-impedance, and manometry testing to minimize cost in treating suspect laryngopharyngeal reflux disease.

OBJECTIVES/HYPOTHESIS: Empiric proton pump inhibitor (PPI) trials for laryngopharyngeal reflux (LPR) are common. A majority of the patients respond to acid suppression. This work intends to evaluate once-daily, 40 mg omeprazole and once-nightly, 300 mg ranitidine (QD/QHS) dosing as an alternative regimen, and use this study's cohort to evaluate empiric regimens prescribed for LPR as compared to up-front testing with pH impedance multichannel intraluminal impedance (MII) with dual pH probes and high-resolution manometry (HRM) for potential cost minimization. STUDY DESIGN: Retrospective cohort review and cost minimization study. METHODS: A chart review identified patients diagnosed with LPR. All subjects were treated sequentially and outcomes recorded. Initial QD/QHS dosing increased after 3 months to BID if no improvement and ultimately prescribed MII and HRM if they failed BID dosing. Decision tree diagrams were constructed to determine costs of two empiric regimens and up-front MII and HRM. RESULTS: Ninety-seven subjects met the criteria. Responders and nonresponders to empiric therapy were identified. Seventy-two subjects (74%) responded. Forty-eight (67% of responders and 49% of all) improved with QD/QHS dosing. Forty-nine (51%) subjects escalated to BID dosing. Twenty-four subjects (33% of responders and 25% of all) improved on BID therapy. Twenty-five subjects (26%) did not respond to acid suppression. Average weighted cost was $1,897.00 per patient for up-front testing, $3,033.00 for initial BID, and $3,366.00 for initial QD/QHS. CONCLUSIONS: An alternate QD/QHS regimen improved the majority who presented with presumed LPR. Cost estimates demonstrate that the QD/QHS regimen was more expensive than the initial BID high-dose PPI for 6 months. Overall per-patient cost appears less with up-front MII and HRM.

Efficacy of proton pump inhibitor in combination with rikkunshito in patients complaining of globus pharyngeus.

OBJECTIVE: Globus pharyngeus (GP) is a common symptom of laryngopharyngeal reflux disease (LPRD), and proton pump inhibitor (PPI) and rikkunshito, a traditional Japanese medicine having prokinetic effect improve LPRD symptoms. In the present study, we examined the efficacy of high-dose PPI in combination with rikkunshito in patients complaining of GP. METHODS: 106 patients complaining of GP without any organic endoscopic findings were enrolled. RESULTS: Patients were first administrated with high-dose PPI alone for 4 to 8 weeks and the symptom was improved in 65 patients. Among 41 patients with PPI-refractory GP, 22 patients were administrated with high-dose PPI in combination with rikkunshito, and the symptom was improved in 14 of 22 patients 4 weeks later. The average value of a modified reflux symptom index of the responders was similar to that of non-responders. Only a few patients had positive values in reflux finding scores in both groups. CONCLUSION: The present findings suggest the existence of a high prevalence of LPRD in patients complaining of GP. The data also suggest that gastroesophageal dysmotility is involved in GP, in addition to excessive acid reflux. The pre-therapeutic laryngopharyngeal symptoms and endoscopic findings could not predict the efficacy of the treatment for GP. J. Med. Invest. 63: 227-229, August, 2016.

Unmet needs in treating laryngo-pharyngeal reflux disease: where do we go from here?

INTRODUCTION: Many patients experience ear, nose and throat symptoms associated with their gastroesophageal reflux disease. These symptoms are purportedly caused by reflux of gastroduodenal contents into the larynx, which leads to laryngopharyngeal reflux (LPR). Various modalities are used to diagnose LPR, including ambulatory pH monitoring, laryngoscopy, and esophagogastroduodenoscopy, as well as a few new emerging diagnostic tests. However, there are still no established diagnostic criteria or gold standard methodologies that can reliably distinguish LPR from other conditions. AREAS COVERED: In this review, we will evaluate currently available diagnostic tests and therapeutic options for patients with laryngeal signs and symptoms of reflux and briefly discuss the development and emergence of new treatments. Numerous studies have investigated the role of proton pump inhibitor therapy in this patient population, but have led to disparate and often inconsistent results. Expert commentary: While a subgroup of patients with LPR appears to respond to PPI therapy, many patients show no symptomatic improvement, particularly with respect to extraesophageal symptoms. As such, there is a vital need to explore alternative treatment options, including anti-reflux surgery, lifestyle changes, and other classes of medications to better address LPR.
