Development of scores assessing the refluxogenic potential of diet of patients with laryngopharyngeal reflux.

OBJECTIVE: To develop clinical tools assessing the refluxogenic potential of foods and beverages (F&B) consumed by patients with laryngopharyngeal reflux (LPR). METHODS: European experts of the LPR Study group of the Young-Otolaryngologists of the International Federation of Oto-rhino-laryngological societies were invited to identify the components of Western European F&B that would be associated with the development of LPR. Based on the list generated by experts, four authors conducted a systematic review to identify the F&B involved in the development of esophageal sphincter and motility dysfunctions, both mechanisms involved in the development of gastroesophageal reflux disease and LPR. Regarding the F&B components and the characteristics identified as important in the development of reflux, experts developed three rational scores for the assessment of the refluxogenic potential of F&B, a dish, or the overall diet of the patient. RESULTS: Twenty-six European experts participated to the study and identified the following components of F&B as important in the development of LPR: pH; lipid, carbohydrate, protein composition; fiber composition of vegetables; alcohol degree; caffeine/theine composition; and high osmolality of beverage. A total of 72 relevant studies have contributed to identifying the Western European F&B that are highly susceptible to be involved in the development of reflux. The F&B characteristics were considered for developing a Refluxogenic Diet Score (REDS), allowing a categorization of F&B into five categories ranging from 1 (low refluxogenic F&B) to 5 (high refluxogenic F&B). From REDS, experts developed the Refluxogenic Score of a Dish (RESDI) and the Global Refluxogenic Diet Score (GRES), which allow the assessment of the refluxogenic potential of dish and the overall diet of the LPR patient, respectively. CONCLUSION: REDS, RESDI and GRES are proposed as objective scores for assessing the refluxogenic potential of F&B composing a dish or the overall diet of LPR patients. Future studies are needed to study the correlation between these scores and the development of LPR according to impedance-pH study.

Dietary modification for laryngopharyngeal reflux: systematic review.

OBJECTIVE: This study aimed to determine the relationship between laryngopharyngeal reflux and dietary modification. METHODS: A systematic review was conducted. The data sources for the study were PubMed, Embase, Cochrane Library and Web of Science. Articles were independently extracted by two authors according to inclusion and exclusion criteria. The outcome focus was laryngopharyngeal reflux improvement through diet or dietary behaviour. RESULTS: Of the 372 studies identified, 7 met our inclusion criteria. In these seven studies, laryngopharyngeal reflux symptoms improved following dietary modifications. However, the studies did not present the independent effect of each dietary factor on laryngopharyngeal reflux. Moreover, only one of the seven studies had a randomised controlled study design. CONCLUSION: The reference studies of dietary modification for laryngopharyngeal reflux patients are not sufficient to provide recommendations.

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.

Phonetic Approaches of Laryngopharyngeal Reflux Disease: A Prospective Study.

OBJECTIVES: The study aimed to explore the impact of the selection of the analyzed time interval on the significance of acoustic measurements used to investigate laryngopharyngeal reflux (LPR) treatment efficacy, and based on these results to develop an alternative statistical approach in data analysis focusing on individual patient vocal behavior. STUDY DESIGN: This is a prospective case series. METHODS: From September 2013 to July 2015, 41 patients with a reflux finding score (RFS) > 7 and a reflux symptom index (RSI) > 13 were enrolled and treated with pantoprazole 20 mg twice daily and diet behavioral changes for 3 months. Voice recordings were performed at baseline and after 3 months of treatment. Most stable time intervals of 1, 2, 3, 4, and 5 seconds, and a 1-second time interval positioned at mid-production, were subjected to acoustic analysis. Based on the latter, we developed an "informativeness coefficient" for each acoustic parameter that aimed at assessing its sensitivity to clinical resolution in the case of LPR disease. RESULTS: Significant clinical improvement (RSI and RFS) was observed after treatment (P < 0.05). The acoustic analysis revealed that acoustic parameters significantly improving from pre- to posttreatment varied across time intervals. The duration and the position of the analyzed time interval in the production yielded considerable differences in the results. Analysis of the informativeness coefficient indicated that jitter, jitter percent, relative average perturbation (RAP), pitch perturbation quotient (PPQ), shimmer (ShdB), shimmer percent (Shim), amplitude perturbation quotient (APQ), and smoothed amplitude perturbation quotient (sAPQ) were the indices most sensitive to medical treatment efficacy, with a coefficient ranging from 75.86% to 86.21%. CONCLUSIONS: Depending on the selection of the time interval over which the acoustic parameters are measured, the potential effect of the treatment may or may not be statistically demonstrated. Future studies are needed to establish standardized methodological procedures for acoustic data analysis.

Removal of oesophageal foreign bodies: comparison between oesophagoscopy and oesophagotomy in 39 dogs.

OBJECTIVES: To compare complication rates and outcomes after removal of oesophageal foreign bodies by endoscopy or by oesophagotomy. METHODS: Retrospective evaluation of medical records of dogs with oesophageal foreign bodies treated by endoscopy and/or oesophagotomy. Postoperative clinical signs, management, length of hospitalisation, type and rate of complications, and time interval to return to eating conventional diet were compared. RESULTS: Thirty-nine dogs diagnosed with oesophageal foreign bodies between 1999 and 2011 were included in the study. Most common breeds included West Highland white terrier, Jack Russell terrier and shih-tzu. Successful endoscopic removal was possible in 24 out of 32 cases (Group 1), while surgical removal was successful in 15 out of 15 cases (7 of which had unsuccessful attempts at endoscopic removal) (Group 2). Length of hospitalisation, time to removal of gastrostomy tube and time to eat conventional diet did not differ between the groups. After foreign body removal, the incidence of oesophagitis, oesophageal stricture and perforation observed during repeated endoscopy were similar between the groups. CLINICAL SIGNIFICANCE: In this retrospective study, removal of oesophageal foreign bodies either by oesophagoscopy or oesophagotomy had a similar outcome.

Extensive protein hydrolysate formula effectively reduces regurgitation in infants with positive and negative challenge tests for cow's milk allergy.

AIM: Cow's milk protein allergy (CMPA) is treated using an elimination diet with an extensive protein hydrolysate. We explored whether a thickened or nonthickened version was best for infants with suspected CMPA, which commonly causes regurgitation/vomiting. METHODS: Diagnosis of CMPA was based on a positive challenge test. We compared the efficacy of two casein extensive hydrolysates (eCH), a nonthickened version (NT-eCH) and a thickened version (T-eCH), using a symptom-based score covering regurgitation, crying, stool consistency, eczema, urticarial and respiratory symptoms. RESULTS: A challenge was performed in 52/72 infants with suspected CMPA and was positive in 65.4%. All confirmed CMPA cases tolerated eCH. The symptom-based score decreased significantly in all infants within a month, and the highest reduction was in those with confirmed CMPA. Regurgitation was reduced in all infants (6.4 ± 3.2-2.8 ± 2.9, p < 0.001), but fell more with the T-eCH (-4.2 ± 3.2 regurgitations/day vs. -3.0 ± 4.5, ns), especially in infants with a negative challenge (-3.9 ± 4.0 vs. -1.9 ± 3.4, ns). CONCLUSION: eCH fulfilled the criteria for a hypoallergenic formula, and the NT-eCH and T-eCH formulas both reduced CMPA symptoms. The symptom-based score is useful for evaluating how effective dietary treatments are for CMPA.

[Laryngopharyngeal reflux--own experience in diagnosis and treatment]. / Laryngologiczny obraz refluksu krtaniowo-gardlowego--doswiadczenia wlasne w diagnozowaniu i leczeniu.

INTRODUCTION: For many years the specialists have been interested in gastroesophageal reflux. The aim of the work is to present our experience in the diagnosis and the treatment of laryngopharyngeal reflux. MATERIAL AND METHODS: We studied 60 patients (35 women and 25 men) aged 25 to 60 (average age - 43), with symptoms of reflux, hospitalized in ENT Department in the years 2010-2011. In all patients in ENT examination laryngitis were stated. Each patient was treated with 24-hour esophageal pH-impedance during gastrological consultation. In case of confirmed reflux disease proper diet and medication blocking the proton pomp were prescribed for a period of 3 months. The check-up included: patient interview, filling the questionnaire, ENT examination and gastrological consultation. The treatment was continued for the next 3 months with patients with sustaining problems of upper airway. RESULTS: Laryngopharyngeal reflux disease was confirmed in all examined patients. After 3 months over 80% patients finished the treatment, the other (13) patients finished their treatment after 6 months. CONCLUSIONS: ENT and gastrological consultations with 24-hour esophageal pH-impedance help with successful diagnosis and curing the reflux disease.

Low-acid diet for recalcitrant laryngopharyngeal reflux: therapeutic benefits and their implications.

OBJECTIVES: Laryngopharyngeal reflux (LPR) is an expensive, high-prevalence disease with a high rate of medical treatment failure. In the past, it was mistakenly believed that pepsin was inactive above pH 4; however, human pepsin has been reported to be active up to pH 6.5. In addition, it has been shown by Western blot analysis that laryngeal biopsy samples from patients with symptomatic LPR have tissue-bound pepsin. The clinical impact of a low-acid diet on the therapeutic outcome in LPR has not been previously reported. To provide data on the therapeutic benefit of a strict, virtually acid-free diet on patients with recalcitrant, proton pump inhibitor (PPI)-resistant LPR, I performed a prospective study of 20 patients who had persistent LPR symptoms despite use of twice-daily PPIs and an H2-receptor antagonist at bedtime. METHODS: The reflux symptom index (RSI) score and the reflux finding score (RFS) were determined before and after implementation of the low-acid diet, in which all foods and beverages at less than pH 5 were eliminated for a minimum 2-week period. The subjects were individually counseled, and a printed list of acceptable foods and beverages was provided. RESULTS: There were 12 male and 8 female study subjects with a mean age of 54.3 years (range, 24 to 72 years). The symptoms in 19 of the 20 subjects (95%) improved, and 3 subjects became completely asymptomatic. The mean pre-diet RSI score was 14.9, and the mean post-diet RSI score was 8.6 (p = 0.020). The mean pre-diet RFS was 12.0, and the mean post-diet RFS was 8.3 (p < 0.001). CONCLUSIONS: A strict low-acid diet appears to have beneficial effects on the symptoms and findings of recalcitrant (PPI-resistant) LPR. Further study is needed to assess the optimal duration of dietary acid restriction and to assess the potential role of a low-acid diet as a primary treatment for LPR. This study has implications for understanding the pathogenesis, cell biology, and epidemiology of reflux disease.

Do the laryngopharyngeal symptoms and signs ameliorate by empiric treatment in patients with suspected laryngopharyngeal reflux?

OBJECTIVES: In clinical practice, antireflux medication is given almost always empirically without pH monitorization. We aimed to evaluate the improving effect of empiric antireflux treatment on layngopharyngeal symptoms and signs in patients with gastroesophageal reflux (GER) and suspected laryngopharyngeal reflux (LPR) according to reflux symptom index (RSI) and reflux finding score (RFS). METHODS: GER was determined by esophagogastroduedonoscopy and biopsy in 127 patients. RSI and RFS were calculated for each patient. The patients with a pathology other than LFR which may be responsible from laryngopharyngeal symptoms and signs were excluded from the study. Fifty patients whom were thought to have LPR according to RSI and RFS comprised the study group. After 12-weeks of antireflux treatment, RSI and RFS were calculated again. The statistical analyses were made according to the changes in the severity and frequency of each symptom and sign. RESULTS: There was statistically significant improvement in RSI and RFS after treatment when compared with initial scores. There was statistically significant improvement in severity of all symptoms and signs. Although there was quantitively decrease in frequency of some signs and symptoms, complete resolution of the disease was not observed generally. CONCLUSION: Empiric antireflux treatment according to RSI and RFS is an effective method. Antireflux treatment has a significant improving effect on laryngopharyngeal symptoms and signs. There may be needed longer times of treatment for complete resolution of symptoms and signs.

Fórmulas especiales / Special formulas

Las fórmulas especiales se utilizan como tratamiento nutricional en situaciones de intolerancia y/o alergia a los componentes de las leches infantiles. Dentro de las fórmulas modificadas en hidratos de carbono, el tipo más frecuentemente utilizado es la leche sin lactosa, sobre todo en casos de intolerancia a esta azúcar secundaria a lesión de la mucosa intestinal. Dado que las fórmulas de soja contienen una proteína no láctea y carecen de lactosa, son las indicadas en la galactosemia. Las fórmulas modificadas en proteínas se utilizan principalmente en cuadros de alergia e intolerancia a proteínas de leche de vaca. Dentro de este grupo están los hidrolizados de alto grado de proteínas de la leche de vaca, las fórmulas elementales y las fórmulas de soja. Estas últimas están indicadas en casos de alergia a las proteínas de la leche de vaca (APLV) de manifestación no digestiva en lactantes mayores de 6 meses de edad. Las fórmulas elementales se utilizan en casos graves de alergia a las PLV que no responden a los hidrolizados de alto grado, frecuentemente en el contexto de múltiples alergias alimentarias, o en casos de daño intestinal grave. Los hidrolizados de proteínas de bajo grado están contraindicados en los cuadros de alergia o intolerancia a las PLV. Las fórmulas antirreflujo deben ser utilizadas sólo en niños seleccionados cuya ganancia ponderal se vea comprometida por las pérdidas de nutrientes asociadas a las regurgitaciones (AU)

Special formulas are used for nutritional treatment in situations of intolerance and/or allergy to components of infant formula. Lactose-free infant formula is mainly used for intolerance to this carbohydrate associated to intestinal mucosa injury. Because soy formulas are lactose-free, they are appropiate for use in infants with galactosemia. Formulas with modified proteins are the most commonly used for infants with cow’s milk allergy or cow’s milk intolerance. The main types of this group are: extensively hydrolyzed formula, soy-based formula and free aminoacid-based formula. Soy formulas are indicated in infants older than 6 month with extra-intestinal symptoms. Free aminoacid-based formula are indicated in more severe cases of milk protein, multiple food allergies resistant to extensively hydrolyzed formula therapy and in cases of severe intestinal damage Partially hydrolyzed formulas are not recommended in infants with cow ́s milk protein allergy. Antiregurgitation formula should be used only in selected infants with failure to thrive caused by excessive nutrient losses associated with regurgitation (AU)
