Exploring the clinical relevance of "Angico Gum": an effective biopolymer for topical protection of oesophageal mucosa in gastroesophageal reflux disease patients.

OBJECTIVES: Angico gum (AG) (Anadenanthera colubrina var. Cebil [Griseb.] Altschul) is utilized by some Brazilian communities to alleviate symptoms from gastroesophageal reflux disease. Here, we aimed to investigate the "in vitro" topical protective capacity of AG on human esophageal mucosa. METHODS: Biopsies of the distal esophageal mucosa were collected from 35 patients with heartburn (24 non-erosive and 11 with erosive oesophagitis (EE)) and mounted in Üssing chambers. AG was applied topically, followed by exposure with acid solution (pH 2.0 or pH 1.0), where transepithelial electrical resistance (TER) and The transepithelial permeability for fluorescein was assessed. The incubation of the AG labeled with FITC in the esophageal mucosa was localized by fluorescence microscopy. KEY FINDINGS: Pretreatment with AG prevented the drop in TER induced by acid solution, as well as significantly decreases the fluorescein permeability in non-erosive patients. The protective effect of AG was sustained for up to 120 min both in biopsies of non-erosive and erosive esophagitis. Confocal microscope images showed mucosal luminal adherence of FITC-labeled AG. CONCLUSION: AG had a prolonged topical protective effect against acid solution in mucosal biopsies of patients with non-erosive and erosive esophagitis.

The Effect of Dexlansoprazole on Gastroesophageal Reflux Disease: A Systematic Review and Meta-Analysis.

This systematic review and meta-analysis evaluated the efficacy of dexlansoprazole (a proton pump inhibitor-PPI) in resolving heartburn, reflux, and other symptoms and complications resulting from gastroesophageal reflux disease (GERD). The study followed PRISMA 2020 and was registered in PROSPERO (CRD42020206513). The search strategy used MeSH and free terms appropriately adapted for each database. Only randomized clinical trials (RCTs) were included. The Cochrane tool (RoB 2.0) was used to assess the risk of bias, and the certainty of evidence was rated using GRADE. Ten RCTs were included. Dexlansoprazole outperformed the placebo and other PPIs in the resolution of heartburn and reflux symptoms in patients with GERD, with benefits during and after treatment, especially in those with moderate and severe symptoms. The meta-analyses indicated that dexlansoprazole at doses of 30 and 60 mg had more 24 h heartburn-free days and nights compared to the placebo medications; no difference was reported between dexlansoprazole at doses of 30 and 60 mg in heartburn-free nights. A low bias risk and a moderate certainty of evidence were observed. This review confirms the therapeutic effect of dexlansoprazole (placebo-controlled) and its improvements in GERD symptoms compared to another PPI. However, the interpretation of the results should be carried out cautiously due to the small number of included studies and other reported limitations.

Diffuse Gastrointestinal Motor Compromise in Patients with Scleroderma: Utility of Minimally Invasive Techniques.

BACKGROUND: Scleroderma is a systemic inflammatory disorder that can compromise the gastrointestinal tract in up to 90% of patients. AIM: The purpose of this work is to characterize esophageal, gastric, and intestinal compromise in patients with scleroderma by means of minimally invasive methods and its association with symptoms and severity of their rheumatological condition. METHODS: Patients with systemic sclerosis were recruited according to the criteria of the American College of Rheumatology. The study of digestive involvement was carried out on four consecutive days: esophageal manometry was performed on the first day, intestinal manometry on the second day, surface electrogastrography on the third, and hydrogen breath test on the fourth. The Mann-Whitney test was used for quantitative variables and the chi-squared test for categorical variables (p < 0.05). RESULTS: A total of 30 patients were included, with an average age of 52.7 years and 93% women. Average disease evolution duration was 6.5 years, 70% with limited variety. Rodnan averaged 12 points, being higher in the diffuse variety. The main symptom was heartburn, followed by abdominal distension, with no differences between subtypes except for diffuse nausea; 80% had intestinal manometric compromise, 76% esophageal manometric compromise, and 30% electrogastrographic compromise. Bacterial overgrowth was evidenced in two-thirds (66%) of the patients, and 23% of the patients had simultaneous esophageal, gastric, and intestinal involvement, which correlated with greater skin involvement but not with gastrointestinal symptoms. CONCLUSIONS: Gastrointestinal involvement in patients with scleroderma is frequent and is observed regardless of the symptoms and clinical characteristics of the latter, except for skin involvement.

Frequency of functional esophageal disorders in patients with refractory reflux symptoms in Lima, Peru.

Gastroesophageal reflux disease (GERD) is a clinical condition in which gastric reflux causes symptoms or damage to the esophageal mucosa. It is managed with proton pump inhibitors, however, up to 45% of patients with suspected GERD are refractory to treatment. It is necessary to establish a true GERD diagnosis by means of a digestive endoscopy, which does not show lesions in approximately 70% of patients. In this scenario, it is necessary to perform an esophageal pH-impedance measurement, a procedure that allows to determine whether exposure to gastric acid is pathological. Of this group, patients with pathological acid exposure are diagnosed as true non-erosive reflux disease (NERD). If, in addition to not presenting esophageal lesions, they have a physiological exposure to gastric acid, they suffer from esophageal hypersensitivity or functional heartburn, which are functional disorders. These require a different approach from that of GERD or NERD, as the symptoms are not due to pathological exposure to gastric acid. The aim was to calculate the frequency of esophageal hypersensitivity and functional heartburn in patients with suspected NERD. This was a cross-sectional study. Data was collected by reviewing pH-impedance and manometry reports, 166 patients were selected. The frequency for functional disorders was 86.15%, being 46.9% for functional heartburn and 39.2% for esophageal hypersensitivity. The frequency of functional disorders was higher than that reported in previous studies. In conclusion, age, psychological conditions, dietary, cultural, ethnic or lifestyle factors inherent to our environment might play important roles in the development of functional disorders.

Comparación del efecto de omeprazol como monoterapia y su combinación con bicarbonato de sodio en el tratamiento de la pirosis moderada a severa: ensayo clínico controlado, aleatorizado y doble ciego / Comparison of the effect of omeprazole monotherapy and its combination with sodium bicarbonate in the treatment of moderate to severe heartburn: a double-blind, randomized controlled clinical trial

Heartburn occurs in 75% of patients with digestive discomfort of any origin and is one of the main symptoms of gastroesophageal reflux disease. Treatment focuses on lifestyle modification and symptomatology management with various drugs; when heartburn is moderate to severe, a proton pump inhibitor is more suitable. Omeprazole (OMZ) combined with sodium bicarbonate (BC) has demonstrated significant and sustained suppression of acid secretion. The objective was to compare the effect of sequential OMZ/BC therapy compared to OMZ monotherapy for the improvement of heartburn in Mexican individuals. The study was a double-blind, randomized, controlled, multicenter clinical study including 277 subjects with moderate to severe heartburn. Patients received 7 days of OMZ/BC and 7 days of OMZ (OMZ/BC7) or 14 days of OMZ (OMZ14). The primary endpoint was defined as the change in the number of days a week that the patient has heartburn, it was evaluated at 14 days. Both treatments reduced time (days) with heartburn by less than 4 days (OMZ14 3.9 vs. 4.2 days OMZ/BC7), as well as duration, number of events and intensity of heartburn. The treatments improved the quality of life, and the control of the symptoms. The proportion of adverse events was lower with OMZ/BC. The non-inferiority of OMZ/BC7 with respect to OMZ14 was verified.

La pirosis se presenta en el 75% de los pacientes con molestias digestivas de cualquier origen y es uno de los principales síntomas de la enfermedad por reflujo gastroesofágico. El tratamiento se enfoca en la modificación del estilo de vida y el manejo de la sintomatología con diversos fármacos; cuando la pirosis es moderada a severa, un inhibidor de la bomba de protones es más adecuado. El omeprazol (OMZ) combinado con bicarbonato de sodio (BC) ha demostrado supresión significativa y sostenida de la secreción ácida. El objetivo fue comparar el efecto de la terapia secuencial de OMZ/BC en comparación con el tratamiento continuo de OMZ para la mejoría de la pirosis en individuos mexicanos. Estudio clínico multicéntrico, doble ciego, controlado, aleatorizado que incluyó 277 sujetos con pirosis moderada a severa. Los pacientes recibieron 7 días de OMZ/BC y 7 días de OMZ (OMZ/BC7) o 14 días de OMZ (OMZ14). La variable primaria fue definida como el cambio del número de días a la semana que el paciente presenta pirosis, se evaluó a los 14 días. Ambos tratamientos redujeron los días con pirosis en menos 4 días (OMZ14 3,9 vs. 4,2 días OMZ/BC7), así como la duración, el número de eventos e intensidad de la pirosis. Los tratamientos mejoraron los indicadores de calidad de vida, y el control del padecimiento. La proporción de eventos adversos fue menor con OMZ/BC. Se comprobó la no-inferioridad de OMZ/BC7 respecto OMZ14.

CORRELATION BETWEEN SYMPTOMS AND REFLUX IN PATIENTS WITH GASTROESOPHAGEAL REFLUX DISEASE.

BACKGROUND: Esophageal symptoms of gastroesophageal reflux are the same in functional heartburn, non-erosive disease, and erosive disease. Their patient-perceived intensity may be related to gastroesophageal reflux intensity. OBJECTIVE: To evaluate whether the symptoms in GERD patients are related to the intensity of gastroesophageal acid reflux. METHODS: To test this hypothesis, 68 patients with heartburn (18 with functional heartburn, 28 with non-erosive reflux disease, and 22 with erosive reflux disease) had their symptoms evaluated by the Velanovich score (which mainly focuses on heartburn) and the Eating Assessment Tool (EAT-10) (which focuses on dysphagia). They were submitted to esophageal endoscopy and then, on another day, they answered the Velanovich and EAT-10 questionnaires and underwent manometry and 24-hour pHmetry (measured 5 cm proximal to the upper border of the lower esophageal sphincter). RESULTS: The Velanovich score was higher in patients with non-erosive and erosive diseases than in those with functional heartburn. The mean EAT-10 score did not differ between functional heartburn, erosive, and non-erosive gastroesophageal reflux disease. Considering the threshold of ≥5 to define dysphagia, 4 (22%) patients with functional heartburn, 12 (43%) with non-erosive disease, and 9 (41%) with erosive disease had dysphagia (P=0.18). There was: a) a moderate correlation between the Velanovich and DeMeester score and between Velanovich score and the percentage of acid exposure time (AET); b) a weak correlation between EAT-10 and DeMeester score and between EAT-10 and acid exposure time. CONCLUSION: There is a moderate positive correlation between heartburn and gastroesophageal reflux measurement. Dysphagia has a weak positive correlation with reflux measurement.

Disruption of the brain-esophagus axis in obese patients with heartburn.

Obesity is a risk factor for gastroesophageal reflux disease. Studies addressing the brain-esophagus axis in obese are lacking. In obese with and without heartburn, we assessed: (i) the brain responses to esophageal acid perfusion during functional brain imaging; (ii) esophageal impedance baseline before and after acid perfusion; and (iii) abdominal fat distribution. In this exploratory study, 26 obese underwent functional magnetic resonance imaging (fMRI) of the brain combined with esophageal acid perfusion. Esophageal impedance baseline was determined before and after fMRI, followed by tomographic quantification of the abdominal fat. Among 26 obese (54% men, 39.7 years old, 33.5 kg/m2), there were 17 with heartburn and 9 without heartburn. Before fMRI, the esophageal impedance baseline was lower in obese with heartburn than without heartburn (median 1187 vs. 1890 Ω; P = 0.025). After acid perfusion, impedance baseline decreased in obese with heartburn (from 1187 to 899 Ω; P = 0.011) and was lower in this group than in obese without heartburn (899 vs. 1614 Ω; P = 0.001). fMRI task-residual analysis showed that obese with heartburn presented higher functional connectivity in several brain regions than obese without heartburn. Abdominal fat area did not differ between obese with and without heartburn either for total (72.8 ± 4.4% vs. 70.3 ± 6.0%; P = 0.280), subcutaneous (42.2 ± 9.0% vs. 37.4 ± 9.0%; P = 0.226), or visceral (30.6 ± 7.9% vs. 33.0 ± 7.8%; P = 0.484). In subjects with obesity, the brain-esophagus axis is disrupted centrally with higher functional brain connectivity and peripherally with decreased esophageal mucosa integrity in the presence of heartburn.

Gastroesophageal Reflux Disease and Idiopathic Lung Fibrosis. From Heartburn to Lung Transplant, and Beyond.

Idiopathic pulmonary fibrosis (IPF) and gastroesophageal reflux disease (GERD) are undoubtedly related. Even though it is not clear yet which one is the primary disease, they certainly interact increasing each other's severity. Symptoms are unreliable to diagnose GERD in patients with IPF, and objective evaluation with pH monitoring and/or bronchoalveolar lavage analysis is mandatory. Pharmacological treatment with proton pump inhibitors (PPIs) may bring control of IPF in few patients, but PPIs do not control reflux but just change the pH of the gastric refluxate. Surgical therapy based on a fundoplication is safe and effective as it controls any type of reflux, independently from the pH of the gastric refluxate. In patients waiting for lung transplantation (if they can tolerate a laparoscopic operation under general anesthesia), a fundoplication before the operation might block the progression of IPF, while after transplantation it might prevent rejection by preventing the bronchiolitis obliterans syndrome.

GASTROESOPHAGEAL REFLUX DISEASE: A PRACTICAL APPROACH.

Gastroesophageal reflux disease (GERD) presents typical manifestations such as heartburn and/or regurgitation as well as atypical manifestations such as throat symptoms, laryngitis, hoarseness, chronic cough, asthma, and sleep alterations. There are two phenotypes of the disease: erosive GERD, when erosions are identified by upper digestive endoscopy, and non-erosive GERD, when the esophageal mucosa presents a normal endoscopic aspect. Relevant clinical findings are usually absent in the physical examination, but it should be highlighted that obesity is an important aggravating factor of reflux. The treatment is established based on clinical findings and, according to the clinical situation, on complementary exams such as upper digestive endoscopy. In dubious cases where a precise diagnosis is required, the indicated test is esophageal pHmetry or impedance-pHmetry. Clinical treatment is divided into behavioral/dietary measures and pharmacological measures. Most patients benefit from clinical treatment, but surgical treatment may be indicated in the presence of a larger hiatal hernia and complications of the disease.

ESOPHAGEAL FUNCTIONAL DISORDERS IN THE PRE-OPERATORY EVALUATION OF BARIATRIC SURGERY.

BACKGROUND: Obesity is an independent risk factor for esophageal symptoms, gastroesophageal reflux disease (GERD), and motor abnormalities. When contemplating bariatric surgery, patients with obesity type III undergo esophagogastroduodenoscopy (EGD) and also esophageal manometry (EMN), and prolonged pHmetry (PHM) as part of their pre-operative evaluation. OBJECTIVE: Description of endoscopy, manometry and pHmetry findings in patients with obesity type III preparing for bariatric surgery, and correlation of these findings with the presence of typical GERD symptoms. METHODS: Retrospective study in which clinical symptoms of GERD were assessed, focusing on the presence of heartburn and regurgitation. All patients underwent EMN, PHM and most of them EGD. RESULTS: 114 patients (93 females-81%), average age 36 years old, average BMI of 45.3, were studied. Typical GERD symptoms were referred by 43 (38%) patients while 71 (62%) were asymptomatic. Eighty two patients (72% of total) underwent EGD and 36 (42%) evidenced esophageal abnormalities. Among the abnormal findings, hiatal hernia was seen in 36%, erosive esophagitis (EE) in 36%, and HH+EE in 28%. An abnormal EMN was recorded in 51/114 patients (45%). The main abnormality was a hypotensive lower esophageal sphincter (LES) in 32%, followed by ineffective esophageal motility in 25%, nutcracker esophagus in 19%, IEM + hypotensive LES in 10%, intra-thoracic LES (6%), hypertensive LES (4%), aperistalsis (2%) and achalasia (2%). Among the 43 symptomatic patients, 23 (53%) had abnormal EMN and 31/71 asymptomatic cases (44%) also presented this finding (P=0.30). PHM showed abnormal reflux in 60/114 patients (53%), with a predominance of bi-positional reflux (42%), followed by supine reflux (33%) and upright reflux (25%). Abnormal PHM was found in 26/43 symptomatic cases (60%) and also among 34/71 asymptomatic cases (48%) (P=0.19). CONCLUSION: Manometric abnormalities were common in obesity type III patients, the most frequent being hypotensive LES, followed by IEM. Most patients were asymptomatic. There was no correlation between the finding of motor abnormalities and the presence of symptoms. More than half the patients had abnormal reflux at PHM. We found no significant correlation between abnormal reflux and the presence of symptoms.

IMPACT OF HEARTBURN AND REGURGITATION ON INDIVIDUALS' WELL-BEING IN THE GENERAL POPULATION: A BRAZILIAN NATIONAL SURVEY.

BACKGROUND: Heartburn and acid regurgitation are typical symptoms usually associated with gastroesophageal reflux disease (GERD). GERD is one of the gastrointestinal diagnosis with higher prevalence worldwide, significantly impairing patients' quality of life. OBJECTIVE: The objective of this study was to analyze the impact of GERD-related symptoms in the Brazilian urban population. METHODS: National telephone survey with community-dwelling Brazilian individuals. Self-reported prevalence and frequency of symptoms (heartburn / regurgitation) were assessed. Individuals rated the impact of symptoms in their general well-being using a numeric scale from 1 to 10 (1 = no impact; 10 = very intense, preventing the person to eat and perform daily routine activities). Descriptive and bivariate statistical analyses were performed. RESULTS: The final sample was comprised of 1,773 subjects, 935 (52.7%) females, an average of 40 years old. The prevalence of heartburn and regurgitation in the past 6 months was 26.2% (n=466) and 11.0% (n=196), respectively. Women presented higher prevalence (heartburn n=266, 28.5% and regurgitation n=119, 12.7%) than men (n=200, 23.1% and n=78, 8.9%, respectively) (P<0.05). Heartburn in the past week was reported by 175 individuals (9.8%), while regurgitation episodes by 67 (3.8%). Absence of impact of the symptom in the overall well-being was observed for 82 subjects (17.6%) with heartburn and 18 individuals (9.2%) with regurgitation. Very intense impact was reported by 46 subjects (9.8%) with heartburn and 41 (20.9%) with regurgitation. Women's well-being was more affected than men's (mean score 5.45 vs 4.71, P<0.05). CONCLUSION: Heartburn and regurgitation were frequent symptoms, women with higher prevalence. These symptoms led to a substantial impact on individuals' well-being, women being more affected.

[Diagnosis of laryngopharyngeal Reflux by Impedance with esophageal pHmetry in children with chronic dysphonia]. / Diagnóstico de Reflujo faringolaríngeo mediante Impedanciometría con pHmetría esofágica en niños con disfonía crónica.

INTRODUCTION: Laryngopharyngeal Reflux (LPR) is the retrograde flow of gastric or duodenal contents into the pharynx and larynx, causing inflammation in the upper aerodigestive tract. Traditionally, a pH monitoring study with an acid reflux index was used. The use of multichannel intraluminal impedance testing with pH monitoring (MII-pH) confirms a causal relationship between suspicious symptoms and LPR. OBJECTIVES: To evaluate LPR diagnosed by MII-pH in the pediatric population consulting due to chronic dysphonia and laryngoscopic findings suggestive of LPR, in addition, to measure the concordance between MII-pH and traditional pH monitoring. PATIENTS AND METHOD: Descriptive, prospective study of patients consulting at the Gastroenterology or Otorhinolaryngology polyclinic due to chronic dysphonia, whose nasofibrolaryngoscopy (NFL) was suggestive of LPR. The patients were hospitalized for a 24-hour MII-pH. Patients with a congenital or acquired morbid history were excluded. Pathological LPR was considered if there were 3 or more acid reflux episodes at the pro ximal level in MII-pH. The frequency of traditional pH monitoring and altered MII-pH and the concordance between both methods were evaluated. RESULTS: 12 patients were recruited, 10 men, 6 to 15 years old. On 9/12, pathological LPR was confirmed by MII-pH, of which 2/9 had traditional pH measurements in normal ranges and 7/9 altered pH measurements. In 3 patients, LPR was ruled out by normal proximal MII-pH. The concordance between MII-pH and traditional pH monitoring was acceptable (kappa 0.4). CONCLUSIONS: 75% of the patients with dysphonia and suggestive NFL showed objective evidence of pathological LPR. Since only with the clinical evaluation, NFL and conventional pH monitoring it is not possible to diagnose LPR, we recommend perform MII-pH for greater diag nostic certainty, avoiding unnecessary treatment, and with unwanted effects in 25% of cases.

ORAL AND PHARYNGEAL TRANSIT IN FUNCTIONAL HEARTBURN.

BACKGROUND: Gastroesophageal reflux disease is associated with slower transit of the bolus through the pharynx and upper esophageal sphincter. Functional heartburn has similar symptoms to gastroesophageal reflux disease, however, the symptoms are not caused by reflux. OBJECTIVE: The aim of this investigation was to evaluate oral and pharyngeal transit in patients with functional heartburn, with the hypothesis that, similar to patients with gastroesophageal reflux disease, they have changes in pharyngeal and upper esophageal sphincter transit time. METHODS: Oral and pharyngeal transit was evaluated by videofluoroscopy in eight women with functional heartburn, five with mild dysphagia for solid foods, and 12 female controls. Controls and patients swallowed in duplicate 5 mL and 10 mL of liquid and paste boluses. RESULTS: No difference in the oral or pharyngeal transit time was found between patients and controls. No aspiration of bolus into the airways was detected in any individual. Pharyngeal residues were detected in the same proportion of swallows, in patients (12.5%) and controls (15.0%), after swallows of 10 mL paste bolus. CONCLUSION: Oral, pharyngeal and upper esophageal sphincter transit time are similar in patients with functional heartburn to healthy controls.

Trânsitos oral e faríngeo na pirose funcional / Oral and pharyngeal transit in functional heartburn

ABSTRACT BACKGROUND: Gastroesophageal reflux disease is associated with slower transit of the bolus through the pharynx and upper esophageal sphincter. Functional heartburn has similar symptoms to gastroesophageal reflux disease, however, the symptoms are not caused by reflux. OBJECTIVE: The aim of this investigation was to evaluate oral and pharyngeal transit in patients with functional heartburn, with the hypothesis that, similar to patients with gastroesophageal reflux disease, they have changes in pharyngeal and upper esophageal sphincter transit time. METHODS: Oral and pharyngeal transit was evaluated by videofluoroscopy in eight women with functional heartburn, five with mild dysphagia for solid foods, and 12 female controls. Controls and patients swallowed in duplicate 5 mL and 10 mL of liquid and paste boluses. RESULTS: No difference in the oral or pharyngeal transit time was found between patients and controls. No aspiration of bolus into the airways was detected in any individual. Pharyngeal residues were detected in the same proportion of swallows, in patients (12.5%) and controls (15.0%), after swallows of 10 mL paste bolus. CONCLUSION: Oral, pharyngeal and upper esophageal sphincter transit time are similar in patients with functional heartburn to healthy controls.

RESUMO CONTEXTO: A doença do refluxo gastroesofágico está associada ao trânsito mais lento do bolo deglutido pela faringe e esfíncter superior do esôfago. Pirose funcional tem sintomas similares aos de doença do refluxo gastroesofágico, entretanto eles não são consequência de refluxo. OBJETIVO: Como na pirose funcional os sintomas são semelhantes aos da doença do refluxo gastroesofágico, o objetivo desta investigação foi avaliar a duração do trânsito do bolo deglutido pela boca, faringe e esfíncter superior do esôfago em pacientes com pirose funcional, com a hipótese de que esses pacientes também apresentem alteração no trânsito. MÉTODOS: Pelo método videofluoroscópico foi avaliado o trânsito oral e faríngeo de oito pacientes do sexo feminino com pirose funcional, cinco com disfagia leve para alimentos sólidos, e 12 indivíduos controles do sexo feminino. Controles e pacientes deglutiram em duplicata 5 mL e 10 mL de bolos com a consistências líquida e pastosa. RESULTADOS: Com bolo líquido e pastoso não houve diferença na duração do trânsito oral, faríngeo e pelo esfíncter superior do esôfago entre controles e pacientes. Não houve aspiração do bolo para as vias aéreas em nenhum indivíduo. Os resíduos faríngeos foram observados na mesma proporção das deglutições em pacientes (12,5%) e controles (15%), com a deglutição de 10 mL de bolo pastoso. CONCLUSÃO: A duração do trânsito oral, faríngeo e pelo esfíncter superior do esôfago foi semelhante nos pacientes com pirose funcional e controles.

Prevalence of non-obstructive dysphagia in patients with heartburn and regurgitation.

OBJECTIVE: Heartburn and regurgitation are the most common gastroesophageal reflux symptoms, and dysphagia could be a possible symptom. This investigation aimed to evaluate the prevalence of non-obstructive dysphagia in patients with heartburn and regurgitation. METHODS: A total of 147 patients (age, 20-70 years; women, 72%) complaining of heartburn and regurgitation, without esophageal stricture, previous esophageal surgery, or other diseases, were evaluated. Twenty-seven patients had esophagitis. The Eating Assessment Tool (EAT-10) was employed to screen for dysphagia; EAT-10 is composed of 10 items, and the patients rate each item from 0 to 4 (0, no problems; 4, most severe symptom). Results of the 147 patients were compared with those of 417 healthy volunteers (women, 62%; control group) aged 20-68 years. RESULTS: In the control group, only two (0.5%) had an EAT-10 score ≥5, which was chosen as the threshold to define dysphagia. EAT-10 scores ≥5 were found in 71 (48.3%) patients and in 55% of the patients with esophagitis and 47% of the patients without esophagitis. This finding indicates a relatively higher prevalence of perceived dysphagia in patients with heartburn and regurgitation and in patients with esophagitis. We also found a positive correlation between EAT-10 scores and the severity of gastroesophageal reflux symptoms based on the Velanovich scale. CONCLUSION: In patients with heartburn and regurgitation symptoms, the prevalence of dysphagia was at least 48%, and has a positive correlation with the overall symptoms of gastroesophageal reflux.

Reflux Symptoms in Gastroparesis: Correlation With Gastroparesis Symptoms, Gastric Emptying, and Esophageal Function Testing.

GOAL: The goal of this study was to determine the relationship of reflux with gastroparesis (Gp), looking both at symptoms and objective testing. BACKGROUND: Gp patients often experience gastroesophageal reflux symptoms. How the severity of reflux correlates with the severity of Gp is not known. STUDY: Patients referred to our academic center with symptoms of Gp completed the Patient Assessment of Upper Gastrointestinal Symptoms, Hospital Anxiety and Depression Scale, and Patient Health Questionnaire (PHQ)-15. They underwent 4-hour gastric emptying scintigraphy; and, if indicated, high-resolution esophageal manometry and esophageal pH impedance (EpHI). RESULTS: Of 755 patients from July 2013 to May 2018, 432 had Gp with Gastroparesis Cardinal Symptom Index (GCSI) total score of 3.2±0.1 (mean±SEM) and heartburn/regurgitation subscore of 2.0±0.1. A fourth (27.1%) of all Gp patients had moderate to very severe heartburn/regurgitation symptoms. Heartburn/regurgitation subscore had strong correlation with GSCI total score (r=0.56, P<0.01), and weak correlation with 4-hour gastric retention (r=0.11, P=0.02). In total, 103 Gp patients underwent EpHI monitoring; time esophageal pH<4 had no correlation with heartburn/regurgitation subscore. Less than half (41.7%) of the patients undergoing EpHI had gastroesophageal reflux disease by EpHI. Gp patients with gastroesophageal reflux disease had more severe 4-hour gastric retention, and more frequently had decreased lower esophageal sphincter resting pressure and esophageal motility disorders. Heartburn/regurgitation subscore had moderate correlation with somatic symptoms, and weak correlations with anxiety and depression. CONCLUSIONS: The severity of reflux symptoms in Gp has strong correlation with GCSI total score, weak correlation with gastric retention, and no correlation with esophageal pH monitoring.
