Severe symptoms of heartburn and retrosternal pain consistent with gastro-esophageal reflux (GER) developed in a patient following placement of a conventional self-expanding 16-24-mm-diameter x 12-cm-long esophageal stent across the gastroesophageal junction to treat an obstructing esophageal carcinoma. A second 18-mm-diameter x 10-cm-long esophageal stent with anti-reflux valve was deployed coaxially and reduced symptomatic GER immediately. Improvement was sustained at 4-month follow-up. An anti-reflux stent can be successfully used to treat significant symptomatic GER after conventional stenting.

Dual pH-multichannel intraluminal impedance (pH-MII) is a sensitive tool for evaluating overall gastroesophageal reflux disease, and particularly for permitting detection of nonacid reflux events. pH-MII technology is especially useful in the postprandial period or at other times when gastric contents are nonacidic. pH-MII was recently recognized by the North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition and the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition as being superior to pH monitoring alone for evaluation of the temporal relation between symptoms and gastroesophageal reflux. In children, pHMII is useful to correlate symptoms with reflux (particularly nonacid reflux), to quantify reflux during tube feedings and the postprandial period, and to assess efficacy of antireflux therapy. This clinical review is simply an evidence-based overview addressing the indications, limitations, and recommended protocol for the clinical use of pH-MII in children. PMID:21240010

Gastro-Esophageal Reflux in Children.

Gastro-esophageal reflux (GER) is common in infants and children and has a varied clinical presentation: from infants with innocent regurgitation to infants and children with severe esophageal and extra-esophageal complications that define pathological gastro-esophageal reflux disease (GERD). Although the pathophysiology is similar to that of adults, symptoms of GERD in infants and children are often distinct from classic ones such as heartburn. The passage of gastric contents into the esophagus is a normal phenomenon occurring many times a day both in adults and children, but, in infants, several factors contribute to exacerbate this phenomenon, including a liquid milk-based diet, recumbent position and both structural and functional immaturity of the gastro-esophageal junction. This article focuses on the presentation, diagnosis and treatment of GERD that occurs in infants and children, based on available and current guidelines.

Pathophysiology of Gastroesophageal Reflux Disease.

PubMed

Tack, Jan; Pandolfino, John E

2018-01-01

The pathogenesis of gastroesophageal reflux disease (GERD) is complex and involves changes in reflux exposure, epithelial resistance, and visceral sensitivity. The gastric refluxate is a noxious material that injures the esophagus and elicits symptoms. Esophageal exposure to gastric refluxate is the primary determinant of disease severity. This exposure arises via compromise of the anti-reflux barrier and reduced ability of the esophagus to clear and buffer the refluxate, leading to reflux disease. However, complications and symptoms also occur in the context of normal reflux burden, when there is either poor epithelial resistance or increased visceral sensitivity. Reflux therefore develops via alterations in the balance of aggressive and defensive forces. Copyright © 2018 AGA Institute. Published by Elsevier Inc. All rights reserved.

Follicular tracheitis (also known as tracheal cobblestoning) is an entity that is poorly described and of unclear significance. The objective of this study was to better define follicular tracheitis and determine the association between the clinical finding of follicular tracheitis on bronchoscopy and objective evidence of gastroesophageal reflux disease. Retrospective chart review of children with recurrent croup having undergone a rigid bronchoscopy and an investigation for gastroesophageal reflux between 2001 and 2013. 117 children with recurrent croup children age 6-144 months were included in the study. Follicular tracheitis was noted on 41% of all bronchoscopies. Fifty-nine percent of all children who underwent bronchoscopy were diagnosed with gastroesophageal reflux on at least one investigation. Forty-nine of 117 children underwent a pH probe study, and 51% were found to have evidence of reflux on this study. Nine children were diagnosed with eosinophilic esophagitis. Three patients underwent a biopsy of the follicular tracheitis lesions, which revealed chronic inflammation. There was no evidence of an association between findings of follicular tracheitis and a positive test for gastroesophageal reflux (p=0.52) or a positive pH probe study (p=0.64). There was no association between follicular tracheitis and subglottic stenosis (p=0.33) or an history of asthma and/or atopy (p=0.19). In children with recurrent croup, follicular tracheitis remains an unspecific finding associated with an inflammatory disorder of unknown etiology. Copyright © 2015 Elsevier Ireland Ltd.

We tested the hypothesis that gastro-esophageal reflux disease is a risk factor for exacerbations in individuals with chronic obstructive pulmonary disease (COPD). Among 9622 participants in the Copenhagen City Heart Study, we identified 1259 individuals with COPD and information on gastro-esophageal reflux disease and the regular use of acid inhibitory treatment. These individuals were followed for 5 years with regard to medically treated COPD exacerbations, which we defined as a short course treatment with oral corticosteroids alone or in combination with antibiotics. We applied a multivariable Cox regression analysis with adjustment for well-established risk factors associated with COPD exacerbations or gastro-esophageal reflux disease, including COPD severity, and symptoms. Individuals with COPD and gastro-esophageal reflux disease had more chronic bronchitis (31 vs 21%, P = 0.004), more breathlessness (39 vs 22%, P < 0.001), and more of them had a history of respiratory infections (6.8 vs 1.4%, P < 0.001) than individuals with COPD but without gastro-esophageal reflux disease. Among individuals with COPD and gastro-esophageal reflux disease, those who did not use acid inhibitory treatment regularly had an increased risk of COPD exacerbations during follow-up, hazards ratio (HR): HR = 2.7 (1.3-5.4, P = 0.006). Individuals with gastro-esophageal reflux disease, using acid inhibitory treatment regularly did not have an increased risk of exacerbations, HR = 1.2 (0.6-2.7, P = 0.63). Gastro-esophageal reflux disease was associated with an increased risk of medically treated exacerbations of COPD, but only in those individuals who did not use acid inhibitory treatment regularly. © 2014 Asian Pacific Society of Respirology.

Acid changes in gastroesophageal reflux with vary component in the food have less been studied, especially carbohydrate. We plan to clarify the effect of different carbohydrate density on low esophageal acid and reflux symptoms of patients with gastroesophgeal reflux disease. Twelve patients (52 ± 12 years old; five female) with gastroesophageal reflux disease were recruited for the prospective crossover study. Each patient was invited for panendoscope, manometry and 24 h pH monitor. The two formulated liquid meal, test meal A: 500 ml liquid meal (containing 84.8 g carbohydrate) and B: same volume liquid meal (but 178.8 g carbohydrate) were randomized supplied as lunch or dinner. Reflux symptoms were recorded. There are significant statistic differences in more Johnson-DeMeester score (p = 0.019), total reflux time (%) (p = 0.028), number of reflux periods (p = 0.026) and longest reflux (p = 0.015) after high carbohydrate diet than low carbohydrate. Total reflux time and number of long reflux periods more than 5 min are significant more after high carbohydrate diet. More acid reflux symptoms are found after high carbohydrate diet. High carbohydrate diet could induce more acid reflux in low esophagus and more reflux symptoms in patients with gastroesophageal reflux disease. Copyright © 2018. Published by Elsevier B.V.

Gastro-esophageal reflux disease is a common condition, affecting 25%-40% of the population. Increasing attention has been paid to the relationship between Helicobacter pylori infection and reflux esophagitis. The aim of this study was to investigate the association between CagA+ H. pylori and endoscopically proven gastro-esophageal reflux disease. The study group included 60 hospital patients with gastro-esophageal reflux disease between 2007 and 2009 as compared with 30 healthy patients from a control group that was age and sex matched. Helicobacter pylori CagA+ was identified by an immunological test (Immunochromatography test) (ACON, USA). Helicobacter pyloriCagA+ was present in 42/60 (70%) of the patients with gastro-esophageal reflux disease and in 11/30 (36.6%) patients in the control group (p=0.002). The Odds ratio = 0.8004 with 95% Confidence Interval = from 0.3188 to 2.0094. The relative risk=1.35 that indicates an association between Helicobacter pylori and disease. The presence of Helicobacter pylori is significantly increased in patients with gastro-esophageal reflux disease as compared with the control group.

Sixty percent of adults has typical symptoms of gastroesophageal reflux in Chile. To report the clinical and laboratory features of patients with gastroesophageal reflux. Five hundred thirty-four patients (255 male) with gastroesophageal reflux were included in a prospective protocol that included clinical analysis, manometry and endoscopy in all patients, barium swallow in 427, scintigraphy in 195, acid reflux test in 359, 24 h pH in 175, and differential potential of gastroesophageal mucosa in 73 patients. There was no correlation between the severity of symptoms and the endoscopical severity. Patients with Barret esophagus were 12 years older, were male in a greater proportion and had a higher proportion of manometrically incompetent sphincters than patients with esophageal reflux but without esophagitis or with erosive esophagitis. Severity of acid reflux, measured with 24 h pH monitoring was proportional to the endoscopical damage of the mucosa. There was a close relationship between the mucosal change limit determined with differential potentials and with endoscopy. No short esophagi were found. Patients with symptoms of gastroesophageal reflux must be assessed using several objective measures to determine the severity of their pathological alterations.

Gastroesophageal reflux and lung disease.

PubMed

Meyer, Keith C

2015-08-01

Gastroesophageal reflux (GER) can cause respiratory symptoms and may trigger, drive and/or worsen airway disorders, interstitial lung diseases and lung allograft dysfunction. Whether lifestyle changes and acid suppression alone can counter and prevent the adverse effects of GER on the respiratory tract remains unclear. Recent data suggest that antireflux surgery may be more effective in preventing lung disease progression in patients with idiopathic pulmonary fibrosis or lung transplant recipients who have evidence of allograft dysfunction associated with the presence of excessive GER. Additional research and clinical trials are needed to determine the role of GER in various lung disorders and identify which interventions are most efficacious in preventing the respiratory consequences of gastroesophageal reflux disease. In addition, measuring biomarkers that indicate that gastric refluxate has been aspirated into the lower respiratory tract (e.g., pepsin and bile acid concentrations in bronchoalveolar lavage fluid) may prove helpful in both diagnosis and therapeutic decision making.

To assess the knowledge and practice of pediatricians about infants with physiological reflux and gastroesophageal reflux disease. 140 pediatricians were interviewed during two scientific events in 2009 and 2010. The questions referred to two clinical cases of infants. One with symptoms of infant regurgitation (physiological reflux) and another with gastroesophageal reflux disease. Among 140 pediatricians, 11.4% (n=16) and 62.1% (n=87) would require investigation tests, respectively for infant regurgitation (physiological reflux) and gastroesophageal reflux disease. A series of upper gastrointestinal exams would be the first requested with a higher frequency. Medication would be prescribed by 18.6% (n=26) in the case of physiological reflux and 87.1% (n=122) in the case of gastroesophageal reflux disease. Prokinetic drugs would be prescribed more frequently than gastric acid secretion inhibitors. Sleeping position would be recommended by 94.2% (n=132) and 92.9% (n=130) of the respondents, respectively for the case of physiological reflux and gastroesophageal reflux disease; however, about half of the respondents would recommend the prone position. Only 10 (7.1%) of the pediatricians would exclude the cow's milk protein from the infants' diet. Approaches different from the international guidelines are often considered appropriate, especially when recommending a different position other than the supine and prescription of medication. In turn, the interviews enable us to infer the right capacity of the pediatricians to distinguish physiologic reflux and gastroesophageal reflux disease correctly.

Background: Prevalence of gastroesophageal reflux disease (GERD) has increased in the last decades, and it is now one of the most common chronic and recurrent diseases. The present study aimed at determining the frequency of gender (sex) and age in Iranian patients with GERD symptoms. Methods: In this study, 803 patients aged 11 to 84 years, with erosive and nonerosive gastroesophageal reflux diseases, based on the questionnaire and esophagogastroduodenoscopy findings, participated. The female group was compared with the male group with respect to age, symptoms, esophageal injury, and hiatus hernia. Results: Of the 803 participants, 60.5% (n= 486) were female, and 69.2% (n= 555) were younger than 50 years. Of those patients older than 50 years, 32.8% (n= 81) were female. Moreover, 31.0% (n= 249) of the patients had erosive esophagitis (ERD), and 69.0% (n= 254) had normal esophageal mucosa (NERD).The female to male ratio was 1/1.06 and 1.94/1 in ERD and NERD patients, respectively. Hiatal hernia was more prevalent in females than in males. Conclusion: Nonerosive reflux disease, as a gastroesophageal reflux disease (GERD), was more common in females than in males. GERD became more prevalent with increase in age. Gender and hiatal hernias were 2 potential risk factors of GERD.

Newborns sleep about 80% of the time. Gastroesophageal reflux disease is prevalent in about 10% of neonatal intensive care unit infants. Concurrent polysomnography and pH-impedance studies clarify the relationship of gastroesophageal reflux with sleep. To characterize spatiotemporal and chemical characteristics of impedance-positive gastroesophageal reflux and define symptom associations in sleep and wake states in symptomatic neonates. We hypothesized that frequency of impedance-positive gastroesophageal reflux events and their association with cardiorespiratory symptoms is greater during sleep. Eighteen neonates underwent concurrent polysomnography with a pH-impedance study. Impedance-positive gastroesophageal reflux events (weakly acidic or acidic) were categorized between sleep versus wake states: Symptom Index = number of symptoms with gastroesophageal reflux/total symptoms*100; Symptom Sensitivity Index = number of gastroesophageal reflux with symptoms/total gastroesophageal reflux*100; Symptom Association Probability = [(1 - probability of observed association between reflux and symptoms)*100]). We analyzed 317 gastroesophageal reflux events during 116 hours of polysomnography. During wake versus sleep, respectively, the median (interquartile range) frequency of impedance-positive gastroesophageal reflux was 4.9 (3.1-5.8) versus 1.4 (0.7-1.7) events/hour (P < 0.001) and the proximal migration was 2.6 (0.8-3.3) versus 0.2 (0.0-0.9) events/hour (P < 0.001). The Symptom Index for cardiorespiratory symptoms for impedance-positive events was 22.5 (0-55.3) versus 6.1 (0-13), P = 0.04, whereas the Symptom Sensitivity Index was 9.1 (0-23.1) versus 18.4 (0-50), P = 0.04, although Symptom Association Probability was similar (P = 0.68). Contrary to our hypothesis, frequency of gastroesophageal reflux in sleep is lower; however, spatiotemporal and chemical characteristics of gastroesophageal reflux and symptom-generation mechanisms are distinct.

The prevalence of gastroesophageal reflux disease (GERD) in South Korea has increased over the past 10 years. Patients with erosive reflux disease (ERD) shows better response to proton pump inhibitors (PPIs) than those with non-erosive reflux disease (NERD). NERD is a heterogeneous condition, showing pathological gastroesophageal reflux or esophageal hypersensitivity to reflux contents. NERD patients with pathological gastroesophageal reflux or hypersensitivity to acid may respond to PPIs. However, many patients with esophageal hypersensitivity to nonacid or functional heartburn do not respond to PPIs. Therefore, careful history and investigations are required when managing patients with refractory GERD who show poor response to conventional dose PPIs. Combined pH-impedance studies and a PPI diagnostic trial are recommended to reveal underlying mechanisms of refractory symptoms. For those with ongoing reflux-related symptoms, split dose administration, change to long-acting PPIs or PPIs less influenced by CYP2C19 genotypes, increasing dose of PPIs, and the addition of alginate preparations, prokinetics, selective serotonin reuptake inhibitors, or tricyclic antidepressants can be considered. Pain modulators, selective serotonin reuptake inhibitors, or tricyclic antidepressants are more likely to be effective for those with reflux-unrelated symptoms. Surgery or endoscopic per oral fundoplication may be effective in selected patients.

Esophageal multichannel intraluminal impedance-pH monitoring has become one of the preferred tests to correlate observed reflux-like behaviors with esophageal reflux events. The Gastroesophageal reflux disease Assessment Symptom Questionnaire is a validated tool used to distinguish infants with gastroesophageal reflux disease from healthy children. The aim of this study was to determine whether the Gastroesophageal reflux disease Assessment Symptom Questionnaire composite symptom scores and individual symptom scores correlate with outcomes in esophageal multichannel intraluminal impedance-pH monitoring. A total of 26 patients with gastroesophageal reflux disease-associated symptoms, aged 0-2 years, for whom both esophageal multichannel intraluminal impedance-pH monitoring and Gastroesophageal reflux disease Assessment Symptom Questionnaire survey results were available were included in the study. Gastroesophageal reflux disease Assessment Symptom Questionnaire score data were collected from a 7-day recall of parent's responses about the frequency and severity of gastroesophageal reflux disease symptoms, which determined the individual symptom scores. The composite symptom scores is the sum of all individual symptom scores. Multichannel intraluminal impedance-pH study results were compared to Gastroesophageal reflux disease Assessment Symptom Questionnaire data using Pearson correlation. Among 26 patients, a total number of 2817 (1700 acid and 1117 non-acid) reflux episodes and 845 clinical reflux behaviors were recorded. There were significant correlations between the reflux index and the individual symptom scores for coughing/gagging/choking (r 2 = 0.2842, p = 0.005), the impedance score and individual symptom scores for coughing/gagging/choking (r 2 = 0.2482, p = 0.009), the reflux symptom index for acid reflux-related coughing/gagging/choking and the individual symptom scores for coughing/gagging/choking (r 2 = 0.1900, p = 0.026), the impedance score and

Proton pump inhibitors and histamine H2 receptor antagonists are two of the most commonly prescribed drug classes for pediatric gastroesophageal reflux disease, but their efficacy is controversial. Many patients are treated with these drugs for atypical manifestations attributed to gastroesophageal reflux, even that causal relation is not proven. To evaluate the use of proton pump inhibitors and histamine H2 receptor antagonists in pediatric gastroesophageal reflux disease through a systematic review. A systematic review was performed, using MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials databases. The search was limited to studies published in English, Portuguese or Spanish. There was no limitation regarding date of publication. Studies were considered eligible if they were randomized-controlled trials, evaluating proton pump inhibitors and/or histamine H2 receptor antagonists for the treatment of pediatric gastroesophageal reflux disease. Studies published only as abstracts, studies evaluating only non-clinical outcomes and studies exclusively comparing different doses of the same drug were excluded. Data extraction was performed by independent investigators. The study protocol was registered at PROSPERO platform (CRD42016040156). After analyzing 735 retrieved references, 23 studies (1598 randomized patients) were included in the systematic review. Eight studies demonstrated that both proton pump inhibitors and histamine H2 receptor antagonists were effective against typical manifestations of gastroesophageal reflux disease, and that there was no evidence of benefit in combining the latter to the former or in routinely prescribing long-term maintenance treatments. Three studies evaluated the effect of treatments on children with asthma, and neither proton pump inhibitors nor histamine H2 receptor antagonists proved to be significantly better than placebo. One study compared different combinations of omeprazole, bethanechol and placebo for the

Upper gastrointestinal endoscopic examination is usually the first step in the evaluation of patients with suspected gastroesopageal reflux disease. The primary aim of this study was to investigate the association between gastroesophageal flap valve function (GEFV) and gastroesophapgeal reflux symptoms in patients undergoing routine upper endoscopy. Patients and methods: 1507 patients were included into the study and the GEFV graded I to IV as follows: Hill I-II: normal GEFV, and Hill III-IV: abnormal GEFV. Patients in abnormal GEFV group had a higher incidence of reflux symptoms compared to normal GEFV group (53.4% vs 47.4% for heartburn p=0.03 and 53.2% vs 42.4% for regurgitation, p<0.01). In abnormal GEFV patients, esophagitis was more common compared to those with normal GEFV (32.6% vs 11.1%, p<0.01). Presence of heartburn and regurgitation (n =556) correlated with Hill III-IV grades (n = 184/556), (sensitivity: 33%, p = 0.003). In contrast, 24.6% (157/638) of patients without reflux symptoms were in abnormal GEFV group. In patients undergoing endoscopy because of reflux symptoms, Grade III-IV valve was detected more commonly in patients with reflux symptoms compared to patients without reflux symptoms (p = 0.01). Patients with abnormal valves (Hill grades III and IV) but without reflux symptoms, esophagitis and hiatal hernia should be evaluated individually by means of the presence of gastroesophageal reflux disease which means that GEFV is not a good indicator of reflux disease. © Acta Gastro-Enterologica Belgica.

Gastroesophageal reflux disease typically manifests as heartburn and regurgitation, but it may also present with atypical or extraesophageal symptoms, including asthma, chronic cough, laryngitis, hoarseness, chronic sore throat, dental erosions, and noncardiac chest pain. Diagnosing atypical manifestations of gastroesophageal reflux disease is often a challenge because heartburn and regurgitation may be absent, making it difficult to prove a cause-and-effect relationship. Upper endoscopy and 24-hour pH monitoring are insensitive and not useful for many patients as initial diagnostic modalities for evaluation of atypical symptoms. In patients with gastroesophageal reflux disease who have atypical or extraesophageal symptoms, aggressive acid suppression using proton pump inhibitors twice daily before meals for three to four months is the standard treatment, although some studies have failed to show a significant benefit in symptomatic improvement. If these symptoms improve or resolve, patients may step down to a minimal dose of antisecretory therapy over the following three to six months. Surgical intervention via Nissen fundoplication is an option for patients who are unresponsive to aggressive antisecretory therapy. However, long-term studies have shown that some patients still require antisecretory therapy and are more likely to develop dysphagia, rectal flatulence, and the inability to belch or vomit.

Gastroesophageal reflux (GER) is common in infancy and mainly treated through nonpharmacological interventions. Knowing the early warning signs of GER is important for nursing assessment. Untreated GER can become acute when an infant fails to gain weight and has recurrent, forceful vomiting. Further investigation of gastroesophageal reflux disease (GERD) is indicated when failure to gain weight, irritability, swallowing difficulties, regurgitation, and respiratory complications occur and should trigger referral to pediatric specialists. This article will share information about uncomplicated GER, GERD, and symptoms of these diagnoses, common screening tests, and treatment options. Copyright © 2017 Elsevier Inc. All rights reserved.

The work is based on an analysis of results of treatment of 643 children with gastroesophageal reflux (operations were performed on 69 of them). Methods of anesthesia are described. Conservative treatment was used in correlation with the degree of reflux-esophagitis. Indications to operations were considered to be as follows: hiatal hernias, reflux-esophagitis in children with cerebral paralysis, failure of conservative treatment in the group of children having no anatomical causes of the reflux. A method of surgical treatment is proposed including a combination of fundoplication with the posterior gastropexy and fixation of the esophagus to the diaphragm at a distance of 3 cm from the gastric cuff (43 cases, no recurrences). In patients with a combination of gastroesophageal reflux with the esophagus stenosis resection of the altered portion was made followed by plasty with a colonic transplant or local tissues (10 patients with the diagnosed Barrett esophagus).

Some patients with gastroesophageal reflux disease experience persistent reflux symptoms despite proton pump inhibitor therapy. These symptoms reduce their health-related quality of life. Our aims were to evaluate the relationship between proton pump inhibitor efficacy and health-related quality of life and to evaluate predictive factors affecting treatment response in Japanese patients. Using the gastroesophageal reflux disease questionnaire, 145 gastroesophageal reflux disease patients undergoing proton pump inhibitor therapy were evaluated and classified as responders or partial-responders. Their health-related quality of life was then evaluated using the 8-item Short Form Health Survey, the Pittsburgh Sleep Quality Index, and the Hospital Anxiety and Depression Scale questionnaires. Sixty-nine patients (47.6%) were partial responders. These patients had significantly lower scores than responders in 5/8 subscales and in the mental health component summary of the 8-item Short Form Health Survey. Partial responders had significantly higher Pittsburgh Sleep Quality Index and Hospital Anxiety and Depression Scale scores, including anxiety and depression scores, than those of responders. Non-erosive reflux disease and double proton pump inhibitor doses were predictive factors of partial responders. Persistent reflux symptoms, despite proton pump inhibitor therapy, caused mental health disorders, sleep disorders, and psychological distress in Japanese gastroesophageal reflux disease patients.

Using the gastroesophageal reflux disease questionnaire, 145 gastroesophageal reflux disease patients undergoing proton pump inhibitor therapy were evaluated and classified as responders or partial-responders. Their health-related quality of life was then evaluated using the 8-item Short Form Health Survey, the Pittsburgh Sleep Quality Index, and the Hospital Anxiety and Depression Scale questionnaires. Sixty-nine patients (47.6%) were partial responders. These patients had significantly lower scores than responders in 5/8 subscales and in the mental health component summary of the 8-item Short Form Health Survey. Partial responders had significantly higher Pittsburgh Sleep Quality Index and Hospital Anxiety and Depression Scale scores, including anxiety and depression scores, than those of responders. Non-erosive reflux disease and double proton pump inhibitor doses were predictive factors of partial responders. Persistent reflux symptoms, despite proton pump inhibitor therapy, caused mental health disorders, sleep disorders, and psychological distress in Japanese gastroesophageal reflux disease patients.

Many food items have been involved in gastro-esophageal reflux disease pathogenesis and dietary modification has been proposed as first-line treatment. Test-based exclusion diets have shown to significantly reduce reflux symptoms. We aimed to assess the patterns of food intolerance in a series of patients with typical gastro-esophageal reflux symptoms (GERS). We retrospectively evaluated all patients with typical reflux symptoms, attending the Centre Study Association on Food Intolerance and Nutrition of Ferrara from January 2010 to October 2015, who resulted positive to at least one food item at the Leucocytotoxic Test. The presence and severity of typical GERS (heartburn and/or acid regurgitation) were assessed using the Gastro-esophageal Reflux Disease Impact Scale (GIS) questionnaire. Only individuals with a GIS Score of at least 5 points were included. Almost all patients (91.1%) were intolerant to at least 5 food items. The most frequent food intolerance (more than 33% of patients) were found for milk (55.4%), lettuce (46.4%), coffee (43.7%), brewer's yeast (42.9%), pork (42.9%), tuna (37.5%), rice (35.7%), sole (34.8%), asparagus (34.8%) and eggs (33.9%). Nine different clusters of food intolerance were detected. Patients with typical gastro-esophageal reflux symptoms seem to have intolerance to multiple food items, some of which (lettuce, brewer's yeast, tuna, rice, sole and asparagus) have not yet been associated to gastro-esophageal reflux disease.

Gastroesophageal reflux disease is a highly frequent disorder classically characterized by the presence of heartburn and/or acid regurgitation that improves with drug therapy that reduces acid content in the stomach. However, especially in patients with non-erosive disease, response to proton pump inhibitors is unsatisfactory in approximately 1 out of 3 patients, and consequently, in these patients, it is important to establish a definitive diagnosis and an alternative therapeutic strategy. In the last few years, advances have been made in knowledge of the physiopathology of reflux, such as identification of the role of the acid pocket in producing reflux, technological advances that allow differentiation among acid reflux, non-acid reflux and slightly acid reflux, and advances in the treatment of reflux with drugs that attempt to act on the barrier function of the esophagogastric junction.

Gastroesophageal reflux disease (GERD) and/or hiatus hernia (HH) are one of the most common disorders of the upper gastrointestinal tract. Despite the positive effect of sleeve gastrectomy (SG) regarding weight loss and improvement in obesity co-morbidities, there are concerns about the development of de novo gastroesophageal reflux disease or worsening the existing GERD after this bariatric operation. Furthermore, controversy exists on the consequences of SG in lower esophageal sphincter function and about the ideal procedure when a hiatus hernia is preoperatively diagnosed or discovered during the laparoscopic SG. This review systematically investigates the incidence, the pathophysiology of GERD and/or HH in morbidly obese individuals before and after SG, and the treatment options for concomitant HH repair during laparoscopic sleeve gastrectomy.

This study was conducted to investigate whether there is a direct association between subjective sleep quality and esophageal acid reflux in patients with gastroesophageal reflux disease. We enrolled patients with classic reflux symptoms for endoscopy and ambulatory pH monitoring. The severity of esophageal mucosal injury was assessed by upper endoscopy. Distal esophageal acid exposure was determined by ambulatory 24-hour pH monitoring. Sleep disturbance was assessed by using the Pittsburgh Sleep Quality Index. In total, 103 patients (53 patients without sleep dysfunction and 50 patients with sleep dysfunction) were studied. Erosive esophagitis was found more in patients with sleep disturbance than in those without sleep disturbance (45% versus 31%, P = 0.04). Abnormal esophageal pH was found more in patients with dysfunction (22%) than in patients without sleep dysfunction (5.7%, P = 0.03). Recumbent acid contact time (%) was greater in patients with sleep disturbance than in those without sleep disturbance (3.7 ± 2.4 versus 1.9 ± 0.9, P = 0.04). Sleep quality score positively correlated with acid contact time (r = 0.32, P = 0.02), prolonged reflux events (r = 0.45, P = 0.008) and longer reflux event (r = 0.28, P = 0.03) during recumbent period. Patients with gastroesophageal reflux disease along with sleep dysfunction are characterized with greater nocturnal acid reflux and more erosive esophagitis. Our study suggests that increased nocturnal acid reflux may play a role in inducing sleep disturbance in patients with gastroesophageal reflux disease.

Surgery for Gastroesophageal Reflux Disease in the Morbidly Obese Patient.

Duke, Meredith C; Farrell, Timothy M

2017-01-01

The prevalence of gastroesophageal reflux disease (GERD) has mirrored the increase in obesity, and GERD is now recognized as an obesity-related comorbidity. There is growing evidence that obesity, specifically central obesity, is associated with the complications of chronic reflux, including erosive esophagitis, Barrett's esophagus, and esophageal adenocarcinoma. While fundoplication is effective in creating a competent gastroesophageal junction and controlling reflux in most patients, it is less effective in morbidly obese patients. In these patients a bariatric operation has the ability to correct both the obesity and the abnormal reflux. The Roux-en-Y gastric bypass is the preferred procedure.

Is Gastroesophageal Reflux Disease and Achalasia Coincident or Not?

PubMed Central

Jung, Da Hyun; Park, Hyojin

2017-01-01

Achalasia and gastroesophageal reflux disease (GERD) are on opposite ends of the spectrum of lower esophageal sphincter dysfunction. Heartburn is the main symptom of GERD. However, heartburn and regurgitation are frequently observed in patients who have achalasia. The diagnosis of achalasia might be delayed because these symptoms are misinterpreted as gastroesophageal reflux. Here, we reviewed the clinical characteristics of patients with the erroneous diagnosis of GERD who actually had untreated achalasia. PMID:27771944

Gastroesophageal reflux disease is a chronic disease with a high incidence worldwide. The various symptoms have substantial impact on the quality of life of affected individuals. A long-term self-management program can increase the ability of patients to make behavioral changes, and health outcomes can improve as a consequence. This study's aim was to evaluate the effectiveness of a self-management program for gastroesophageal reflux disease. A total of 115 patients with gastroesophageal reflux disease were allocated to the experimental group and the control group. The former received self-management intervention along with conventional drug therapy, whereas the latter received standard outpatient care and conventional drug therapy. After the clinical trial, the control group also received the same self-management intervention. The levels of self-management behaviors, self-efficacy, gastroesophageal reflux disease symptoms, and psychological condition were compared. Those in the experimental group demonstrated significantly higher self-efficacy for managing their illness, showed positive changes in self-management behaviors, and had comparatively better remission of symptoms and improvement in psychological distress. The program helped patients with gastroesophageal reflux disease self-manage their illness as possible.

there are many questions and little evidence regarding the diagnosis and treatment of gastroesophageal reflux disease (GERD) in children. The association between GERD and cow's milk protein allergy (CMPA), overuse of abdominal ultrasonography for the diagnosis of GERD, and excessive pharmacological treatment, especially proton-pump inhibitors (PPIs) are some aspects that need clarification. This review aimed to establish the current scientific evidence for the diagnosis and treatment of GERD in children. a search was conducted in the MEDLINE, PubMed, LILACS, SciELO, and Cochrane Library electronic databases, using the following keywords: gastroesophageal reflux; gastroesophageal reflux disease; proton-pump inhibitors; and prokinetics; in different age groups of the pediatric age range; up to May of 2013. abdominal ultrasonography should not be recommended to investigate gastroesophageal reflux (GER). Simultaneous treatment of GERD and CMPA often results in unnecessary use of medication or elimination diet. There is insufficient evidence for the prescription of prokinetics to all patients with GER/GERD. There is little evidence to support acid suppression in the first year of life, to treat nonspecific symptoms suggestive of GERD. Conservative treatment has many benefits and with low cost and no side-effects. there have been few randomized controlled trials that assessed the management of GERD in children and no examination can be considered the gold standard for GERD diagnosis. For these reasons, there are exaggerations in the diagnosis and treatment of this disease, which need to be corrected. Copyright © 2013 Sociedade Brasileira de Pediatria.

Endoscopic and laparoscopic treatment of gastroesophageal reflux.

PubMed

Watson, David I; Immanuel, Arul

2010-04-01

Gastroesophageal reflux is extremely common in Western countries. For selected patients, there is an established role for the surgical treatment of reflux, and possibly an emerging role for endoscopic antireflux procedures. Randomized trials have compared medical versus surgical management, laparoscopic versus open surgery and partial versus total fundoplications. However, the evidence base for endoscopic procedures is limited to some small sham-controlled studies, and cohort studies with short-term follow-up. Laparoscopic fundoplication has been shown to be an effective antireflux operation. It facilitates quicker convalescence and is associated with fewer complications, but has a similar longer term outcome compared with open antireflux surgery. In most randomized trials, antireflux surgery achieves at least as good control of reflux as medical therapy, and these studies support a wider application of surgery for the treatment of moderate-to-severe reflux. Laparoscopic partial fundoplication is an effective surgical procedure with fewer side effects, and it may achieve high rates of patient satisfaction at late follow-up. Many of the early endoscopic antireflux procedures have failed to achieve effective reflux control, and they have been withdrawn from the market. Newer procedures have the potential to fashion a surgical fundoplication. However, at present there is insufficient evidence to establish the safety and efficacy of endoscopic procedures for the treatment of gastroesophageal reflux, and no endoscopic procedure has achieved equivalent reflux control to that achieved by surgical fundoplication.

The diagnosis of gastro-esophageal reflux disease cannot be made with barium esophagograms.

For over 50 years, barium studies have been used to diagnose gastro-esophageal reflux disease (GERD), but the value of this test is controversial. Our study aimed to determine if barium esophagograms can be used to diagnose GERD. Barium esophagograms and pH-impedance measurement were performed in 20 subjects with reflux symptoms. pH-impedance measurements were used as gold standard for the diagnosis of GERD. Gastro-esophageal reflux measured with the barium study was defined as a positive outcome. 50% of patients presented gastro-esophageal reflux on the barium esophagogram. No significant differences were observed in acid exposure time between subjects with (median: 7.4%; interquartile range, IQR: 8.4%) or without reflux at barium esophagography (median: 5.95%; IQR: 13.05%; p > 0.05). Nor did we find differences in median proximal extent of reflux measured with impedance monitoring between patients with a positive (median: 6.7%; IQR: 1.95%) and negative barium study (median: 7.1%; IQR: 0.68%; p > 0.05). Patients with reflux on barium esophagogram did not have a positive symptom association probability more often than those who did not have reflux at barium esophagography. Lastly, there were no differences in numbers of acid, weakly acidic or total reflux episodes between those with positive or negative barium esophagogram (p > 0.05). No correlations were found between the maximum proximal extent of gastro-esophageal reflux during esophagography and pH-impedance parameters. Presence or absence of gastro-esophageal reflux during barium esophagography does not correlate with incidence or extent of reflux observed during 24-h pH-impedance monitoring and is not of value for the diagnosis of GERD. © 2014 John Wiley & Sons Ltd.

The costs of gastroesophageal reflux disease have not been assessed in Asia, even though the prevalence of gastroesophageal reflux disease is gradually increasing. We evaluated work presenteeism and absenteeism as indirect costs of gastroesophageal reflux disease in Korea. This was a cross-sectional and multicentre study using patient-reported outcome instruments. A total of 1009 full-time employees who visited the gastrointestinal department for any reason (281 patients with gastroesophageal reflux disease and 728 controls) were included. Main outcomes were presenteeism and absenteeism measured as work productivity loss and monetary cost per week. Absenteeism and presenteeism were significantly higher in the gastroesophageal reflux disease than the control group (1.49% vs. 0.46%, P=0.0010; 34.13% vs. 9.23%, P<0.0001). Loss of work productivity was significantly greater in the gastroesophageal reflux disease than the control group (33.09% vs. 9.02%; P<0.0001). This loss of work productivity difference between the two groups represented an additional productivity loss of 11.7h/week in the gastroesophageal reflux disease group compared with the control group. Assuming average hourly wages of $14.12, the weekly burden of gastroesophageal reflux disease reached $165.07 per person. Gastroesophageal reflux disease was associated with substantial work productivity loss, mainly due to presenteeism rather than absenteeism, in Korean full-time employees.

A Review of New Surgical and Endoscopic Therapies for Gastroesophageal Reflux Disease.

Ganz, Robert A

2016-07-01

Treatment of gastroesophageal reflux disease in the United States today is binary, with the majority of patients with gastroesophageal reflux disease being treated with antisecre-tory medications and a minority of patients, typically those with volume regurgitation, undergoing Nissen fundoplication. However, there has been increasing dissatisfaction with proton pump inhibitor therapy among a significant number of patients with gastroesophageal reflux disease owing to cost, side effects, and refractory symptoms, and there has been a general reluctance to undergo surgical fundoplication due to its attendant side-effect profile. As a result, a therapy gap exists for many patients with gastroesophageal reflux disease. Alternative techniques are available for these gap patients, including 2 endoscopic fundoplication techniques, an endoscopic radiofrequency energy delivery technique, and 2 minimally invasive surgical procedures. These alternative techniques have been extensively evaluated; however, there are limitations to published studies, including arbitrary definitions of success, variable efficacy measurements, deficient reporting tools, inconsistent study designs, inconsistent lengths of follow-up postintervention, and lack of comparison data across techniques. Although all of the techniques appear to be safe, the endoscopic techniques lack demonstrable reflux control and show variable symptom improvement and variable decreases in proton pump inhibitor use. The surgical techniques are more robust, with evidence for adequate reflux control, symptom improvement, and decreased proton pump inhibitor use; however, these techniques are more difficult to perform and are more intrusive. Additionally, these alternative techniques have only been studied in patients with relatively normal anatomy. The field of gastroesophageal reflux disease treatment is in need of consistent definitions of efficacy, standardized study design and outcome measurements, and improved reporting

Refractory gastroesophageal reflux disease

Subramanian, Charumathi Raghu; Triadafilopoulos, George

2015-01-01

Gastroesophageal reflux disease (GERD) is a condition that develops when the reflux of stomach contents into the esophagus causes troublesome symptoms, esophageal injury, and/or complications. Use of proton pump inhibitors (PPI) remains the standard therapy for GERD and is effective in most patients. Those whose symptoms are refractory to PPIs should be evaluated further and other treatment options should be considered, according to individual patient characteristics. Response to PPIs could be total (no symptoms), partial (residual breakthrough symptoms), or absent (no change in symptoms). Patients experiencing complete response do not usually need further management. Patients with partial response can be treated surgically or by using emerging endoscopic therapies. Patients who exhibit no response to PPI need further evaluation to rule out other causes. PMID:25274499

Bronchiolitis obliterans syndrome is a significant postallogeneic hematopoietic stem cell transplant problem. Recent data in lung transplant patients suggest an association with gastroesophageal reflux disease and bronchiolitis obliterans syndrome. We studied posthematopoietic stem cell transplant patients with bronchiolitis obliterans syndrome for gastroesophageal reflux disease and its response to a proton pump inhibitor. Seven postallogeneic hematopoietic stem cell transplant patients with bronchiolitis obliterans syndrome were studied. Gastroesophageal reflux disease was assessed by 24-hour pH monitoring with a Bravo catheter-free radio pH capsule. Patients with positive gastroesophageal reflux disease were started on omeprazole. Pretreatment and posttreatment pulmonary function tests were done at 3-month intervals. Of 7 patients, 5 had positive results for gastroesophageal reflux disease (71%). Omeprazole had a disease-stabilizing effect on the patients' pulmonary function tests. Our study shows a significant association between bronchiolitis obliterans syndrome and gastroesophageal reflux disease in postallogeneic hematopoietic stem cell transplant patients. Use of omeprazole may have a disease-stabilizing effect in short-term follow-up.

Associations between peripheral vertigo and gastroesophageal reflux disease.

We hypothesize that peripheral vertigo is associated with gastroesophageal reflux disease (GERD). Two mechanisms could be considered – gastric acids may directly irritate the respiratory mucosa and cause inflammation, or Helicobacter pylori (H. pylori) could be present and cause local infection. Reflux material (Hydrochloric acid (HCl) and pepsin) could get into the middle ear via Eustachian tube and affect osseous structures directly. Disturbance of ossicles could cause tinnitus, which is more common for peripheral vertigo. H. pylori could also get in the esophagus and in the upper respiratory tract via gastroesophageal reflux, and could cause tympanosclerosis and fixation of ossicles. In our study group, 120 of 153 (78.4%) patients had gastroesophageal reflux disease (GERD). Diagnostic tests of H. pylori (rapid urease test or blood antibody test) were performed for 96 of 120 (80%) patients with GERD and were found positive for 32 of 96 (33.3%) patients. Peripheral vertigo was present in 93 of 120 (77.6%) patients with GERD compared to 33 of 126 (26%) patients without GERD (χ(2)=9.016, p=0.003). H. pylori and peripheral vertigo coexisted in 26 of 126 patients (20.6%) (OR 1.36; 95% CI 0.49-3.74, p=0.55). Our study demonstrated statistically significant association between peripheral vertigo and GERD but not between peripheral vertigo and H. pylori. Further more extensive investigations are needed in order to explore our hypothesis. Copyright © 2015 Elsevier Ltd. All rights reserved.

Studies have shown that gastroesophageal reflux disease occurs more frequently than expected in children with chronic rhinosinusitis. The objective of this study is to further understand the relationship of pediatric chronic rhinosinusitis and gastroesophageal reflux disease in children with symptoms of rhinorrhea, nasal congestion, and chronic cough. A retrospective chart review of 63 children, ages 6 months to 10 years old with rhinorrhea, nasal congestion, and chronic cough. The patients underwent maxillary cultures, adenoidectomy, and distal third esophageal biopsies. Children with esophageal biopsies showing esophagitis were classified as positive for gastroesophageal reflux disease, and maxillary antral swabs growing a high density of bacteria were classified as positive for chronic rhinosinusitis. Six months to 5 years old children (n=43), 6 (14%) had simultaneous positive maxillary antral cultures and positive esophageal biopsies, 11 (26%) had positive esophageal biopsies alone, 23 (53%) had positive maxillary antral cultures alone, and 3 (7%) had neither. Six to 10 years old children (n=20), 9 (45%) had simultaneous positive maxillary antral cultures and positive esophageal biopsies, 1 (5%) patient had positive esophageal biopsies alone, 3 (15%) patients had positive maxillary antral cultures alone, and 7 (35%) patients had neither. Twenty-seven (42%) of the patients from the whole study had gastroesophageal reflux positive biopsies. The younger children were statistically likely to have chronic rhinosinusitis and gastroesophageal reflux disease independently of each other (p=0.0002). A direct group comparison found the younger group to have independent chronic rhinosinusitis and gastroesophageal reflux disease and the older group to have simultaneous chronic rhinosinusitis and gastroesophageal reflux disease (p=0.0006). In children with the presenting symptoms of rhinorrhea, nasal congestion, and chronic cough, younger children tend to have either chronic

In infants, it is not always easy to distinguish between pathological and physiological gastroesophageal reflux based only on clinical criteria. In Brazil, studies about gastroesophageal reflux disease in infants are few and are even rare those that used prolonged esophageal pH monitoring for its evaluation. To describe the clinical features of gastroesophageal reflux disease and to determine its prevalence in infants with gastroesophageal reflux attending a tertiary Pediatric Gastroenterology Service and submitted to esophageal pH monitoring for investigation. Descriptive study in 307 infants in whom esophageal pH monitoring (Mark III Digitrapper, Synectics Medical AB, Sweden) was performed during the period December, 1998-December, 2008. The clinical features studied were age group (1-12 months and 13-24 months), and clinical manifestations that motivated the indication of pH monitoring. One hundred twenty-four (40.4%) were female and 183 (59.6%) male with mean age 12.2 +/- 6.2 months (1-23 months). The prevalence of gastroesophageal reflux disease was 18.2% (56/307). One hundred forty-eight (48.2%) were 1-12 months old and 159 (51.8%), 13-24 months. No significant difference was found between the prevalence of these two age groups (P = 0.3006). Gastroesophageal reflux disease was more frequent in those with digestive manifestations (24.2%), crisis of cyanosis/apnea (23.8%) and mixed manifestations (21.5%). Respiratory manifestations were the most frequent indication (39.1%) of pH monitoring. However, the prevalence of gastroesophageal reflux disease was lower (12.5%) in this group compared with in those with digestive manifestations (P = 0.0574), crisis of cyanosis/apnea (P = 0.0882) and mixed manifestations (P = 0.1377). All infants that presented clinical manifestations as crisis of cyanosis/apnea and abnormal pH-metry were < 3 months of age. In our Service, the prevalence of gastroesophageal reflux disease associated with acid reflux in infants revealed

Chronic regurgitation of gastric acids in patients with gastroesophageal reflux disease may cause dental erosion, which can lead in combination with attrition or bruxism to extensive loss of coronal tooth tissue. This clinical report describes treatment of severe tooth wear of a gastroesophageal reflux disease patient who is 54-year-old Turkish male patient. After his medical treatment, severe tooth wear, bruxism and decreased vertical dimensions were determined. The vertical dimension was re-established and maxillary and mandibular anterior and posterior teeth were prepared for metal-ceramic restorations. Metal-ceramic fixed partial dentures were fabricated as full mouth restorations for both maxillary and mandibular arches because of splinting all teeth. And then maxillary stabilization splint was fabricated for his bruxism history. Significant loss of coronal tooth structure must taken into consideration. Gastroesophageal reflux disease by itself or in combination with attrition, abrasion or bruxism may be responsible for the loss. An extensive diagnostic evaluation is essential for the medical and dental effects of the problem.

We aimed to establish the prevalence and demographic determinants of gastroesophageal reflux disease in the Turkish general population using the Turkish version of the gastroesophageal reflux disease questionnaire. A total of 8143 volunteers (mean age: 38.5 (13.3) years; 52.3% males) were included in this cross-sectional questionnaire study conducted via face-to-face administration of the questionnaire forms including items on sociodemographic features, past history of gastric disorders, gastroesophageal reflux disease, the influence of reflux symptoms on patients' lives, physician visits, diagnostic tests, and reflux medications. A past history of gastric symptoms was reported in half of the population. More female participants (p<0.001) had a past history of gastric symptoms that yielded a previous diagnosis of gastroesophageal reflux disease in 19.1% of the population. The likelihood of gastroesophageal reflux disease was low in the majority (75.3%) of the subjects evaluated. Gastroesophageal reflux disease with an inconveniencing or disrupting impact on the patient's life was present in 17.9% and 6.8% of the population. Total gastroesophageal reflux disease-questionnaire scores and reflux prevalence were higher in older age groups (p<0.001). Females were more likely to have gastroesophageal reflux disease prevalence based on reflux symptoms. The impact of gastroesophageal reflux disease on sleep and psychological/emotional well-being was more pronounced in older and female patients, whereas the impact on eating/drinking behaviors and physical-social activities was more marked among females independent of their age (p<0.001). Reflux prevalence was higher in subjects from East Anatolia, Central Anatolia, Mediterranean, and Black Sea regions of Turkey (p<0.001 for each). Prevalence and demographic determinants of gastroesophageal reflux disease are compatible with the profile of the disease in the other Western populations, with a predilection for females and

What is the real impairment on esophageal motility in patients with gastroesophageal reflux disease?

2013-04-01

Impairment of esophageal motility is a common finding in patients with gastroesophageal reflux disease (GERD) as reduced lower esophageal sphincter (LES) basal pressure. A very low LES pressure might facilitate the occurrence of more gastroesophageal reflux whereas abnormal esophageal peristalsis may contribute to impaired esophageal clearance after reflux. Evaluate the esophageal motor function of the lower esophageal sphincter and esophageal body in the various forms of gastroesophageal reflux disease. The manometrics records of 268 patients, who had evaluation of the esophageal motility as part of the diagnostic gastroesophageal reflux disease were split into four groups, as follows: 33 patients who had no esophagitis; 92 patients who had erosive esophagitis; 101 patients who had short Barrett's esophagus and 42 patients who had long Barrett's esophagus. The group who had long Barrett's esophagus showed smaller mean LES pressure and higher percentage of marked LES hypotonia; in the distal segment of the esophageal body the this group showed higher percentage of marked hypocontractility of the distal segment (<30 mm Hg); this same group showed higher percentage of esophageal motility disorders. The most intense esophageal motility disorders and lower pressure of lower esophageal sphincter were noted in the group with long Barrett's esophagus. Those with reflux esophagitis and short Barrett's esophagus had esophageal motility impairment, intermediate among patients with esophagitis and long Barrett's esophagus. Patients with typical symptoms of gastroesophageal reflux but without esophagitis by endoscopy study showed no impairment of esophageal motility.

Gastroesophageal reflux is the cause of some cases of chronic cough; and also has a postulated role in the aetiology of Idiopathic Pulmonary Fibrosis. A high prevalence of acid; and more recently non-acid, reflux has been observed in Idiopathic Pulmonary Fibrosis cohorts. Therefore, gastroesophageal reflux may be implicated in the pathogenesis of cough in Idiopathic Pulmonary Fibrosis. Methods Eighteen subjects with Idiopathic Pulmonary Fibrosis underwent 24-hour oesophageal impedance and cough count monitoring after the careful exclusion of causes of chronic cough other than gastroesophageal reflux. All 18 were then treated with high dose acid suppression therapies. Fourteen subjects underwent repeat 24-hour oesophageal impedance and cough count monitoring after eight weeks. Results Total reflux and acid reflux frequencies were within the normal range in the majority of this cohort. The frequencies of non-acid and proximal reflux events were above the normal range. Following high dose acid suppression therapy there was a significant decrease in the number of acid reflux events (p = 0.02), but an increase in the number of non-acid reflux events (p = 0.01). There was no change in cough frequency (p = 0.70). Conclusions This study confirms that non-acid reflux is prevalent; and that proximal oesophageal reflux occurs in the majority, of subjects with Idiopathic Pulmonary Fibrosis. It is the first study to investigate the effect of acid suppression therapy on gastroesophageal reflux and cough in patients with Idiopathic Pulmonary Fibrosis. The observation that cough frequency does not improve despite verifiable reductions in oesophageal acid exposure challenges the role of acid reflux in Idiopathic Pulmonary Fibrosis associated cough. The finding that non-acid reflux is increased following the use of acid suppression

The mass-spectra of proteome of blood serum from healthy children and children with gastroesophageal reflux disease were received. The technology platform including direct proteome mass-spectrometer profiling after pre-fractional rectification using magnetic particles MB WCX was applied. The significant differences in mass-spectra were established manifesting in detection of more mass-spectrometer peaks and higher indicators of their intensity and area in group of healthy children. The study detected 39 particular peptides and low-molecular proteins predominantly intrinsic to healthy or ill children. It was established that two peptides with molecular mass 925 and 909 Da. are registered only in healthy patients and have no traces in group ofpatients with gastroesophageal reflux disease. The peptide 1564 Da is detected only in blood of children with gastroesophageal reflux disease and totally is absent in healthy children. The research data permitted to reveal specific patterns (signatures) of low-molecular proteins and peptides specific for blood serum of healthy children and patients with gastroesophageal reflux disease. The results testify the availability of singularities in metabolism of low-molecular proteins and can be used as a basis for development of minimally invasive mass-spectrometer system for its diagnostic.

The relationship between chronic obstructive pulmonary disease (COPD) exacerbations and gastroesophageal reflux (GER) has been investigated less than asthma-GER. We aimed to evaluate the presence of GER in patients with COPD and its impact on exacerbations. We included 24 patients with stable mild-moderate stage COPD and 19 volunteers as the control group. We conducted a gastroesophageal reflux disease (GERD) symptom questionnaire, gastroscopy, manometry, and an ambulatory 24-h pH-impedance study. According to the GERD questionnaire, only 5 (20.8%) patients with COPD had typical GER symptoms. According to the 24-h pH-impedance study, the mean DeMeester score (DMS) was 38.1 ± 34.6 in the COPD group and 13.3 ± 16.8 in the control group (p = 0.01). The acid reflux (DMS > 14.7) rate was higher in patients with COPD than in controls (73.9% vs 26.3%, p = 0.01). The symptom association probability positivity rate was 17.4% (n = 4) in the COPD group, which was similar to the controls (p = 0.11). The mean proximal extension rate of reflux (Z 17 cm) was 26.4 ± 12.9% in the COPD group. The proximal extent of reflux was positively correlated with the number of COPD exacerbations per year (p = 0.03, r = 0.448). In the motility results, only 2 (20%) patients in the control group had a minor motility disorder. Seventeen (70.8%) patients in the COPD group had a minor motility disorder, and 4 (16.7%) had major motility disorders (p < 0.001). In our study, gastroesophageal reflux was frequent in patients with COPD, but only a quarter had typical reflux symptoms. The proximal extent of reflux may trigger frequent exacerbations of COPD.

- Gastroesophageal reflux disease is the most common esophageal disorder in pediatrics. - The aim of this study was to compare reflux parameters of typical and atypical symptoms of gastroesophageal reflux disease using 24-hour esophageal pH monitoring and multichannel intraluminal impedance in pediatric population. - In this prospective study, 43 patients aged less than 18 year with suspected gastroesophageal reflux disease were enrolled. The patients were divided into two groups based on the main presenting symptoms (typical versus atypical). Twenty four-hour pH monitoring and multichannel intraluminal impedance were performed in all the patients for comparing these two group regarding association of symptoms and reflux. Number of refluxes, pH related reflux, total reflux time, reflux more than 5 minutes, longest time of the reflux, lowest pH at reflux, reflux index were recorded and compared. Data comparison was done using SPSS. - The mean age of the patients was 5.7±3.4 years and 65.1% were male. Out of 43 patients 24 cases had typical symptoms and 19 had atypical symptoms. The mean reflux events detected by multichannel intraluminal impedance was more than mean reflux events detected by pH monitoring (308.4±115.8 vs 69.7±66.6) with P value of 0.037, which is statistically significant. The mean symptom index and symptom association probability were 35.01% ± 20.78% and 86.42% ± 25.79%, respectively in multichannel intraluminal impedance versus 12.73% ± 12.48% and 45.16% ± 42.29% in pH monitoring (P value <0.001). Number of acid reflux was 46.26±47.16 and 30.9±22.09 for atypical and typical symptoms respectively. The mean symptom index was 18.12% ± 13.101% and 8.30% ± 10.301% in atypical and typical symptoms respectively (P=0.034). Bolus clearance was longer in atypical symptoms compared typical symptoms(P<0.05). - Symptom index was significantly higher in atypical symptoms compared to typical symptoms. Higher number of acid reflux was found in children

The possible pathophysiology of the relationship between gastro-esophageal reflux disease and apnea of prematurity has been widely investigated. Various physiological protective reflex responses provide a plausible biological link between gastro-esophageal reflux and apnea of prematurity. It is uncertain whether or not there is a causal relationship between the two diseases. PATIENT'S FINDINGS: Twins were admitted to the neonatal intensive care unit due to feeding problems. Physical examination was normal except for reticulated, blueviolet skin changes. Short apneic attacks occurred on the first day in twin 1 and on the second day in twin 2, and these were initially treated by stimulation and increased ambient O2 concentration. Then, we conducted methylxanthine and continuous positive airway pressure treatment. Laboratory and radiological analysis were normal. As gastro-esophageal reflux disease was thought to be the causes of the treatment-refractory apnea, therapy with gaviscon and domperidon was begun for both cases. Apneic attacks did not recur after gaviscon and domperidon therapy. Pharmacological therapy for gastro-esophageal reflux disease has not definitively been shown to be effective in improving symptoms and hence, should be reserved especially for infants with treatment refractory apnea episodes suspected as being gastro-esophageal reflux in premature infants.

Introduction Chronic regurgitation of gastric acids in patients with gastroesophageal reflux disease may cause dental erosion, which can lead in combination with attrition or bruxism to extensive loss of coronal tooth tissue. Case presentation This clinical report describes treatment of severe tooth wear of a gastroesophageal reflux disease patient who is 54-year-old Turkish male patient. After his medical treatment, severe tooth wear, bruxism and decreased vertical dimensions were determined. The vertical dimension was re-established and maxillary and mandibular anterior and posterior teeth were prepared for metal-ceramic restorations. Metal-ceramic fixed partial dentures were fabricated as full mouth restorations for both maxillary and mandibular arches because of splinting all teeth. And then maxillary stabilization splint was fabricated for his bruxism history. Conclusion Significant loss of coronal tooth structure must taken into consideration. Gastroesophageal reflux disease by itself or in combination with attrition, abrasion or bruxism may be responsible for the loss. An extensive diagnostic evaluation is essential for the medical and dental effects of the problem. PMID:19830044

Background/Aims Little data exists about esophageal body dysmotility and reflux patterns in refractory gastroesophageal reflux disease (RGERD) patients off therapy. We aimed to evaluate effects of esophageal body dysmotility on reflux parameters in RGERD patients by combining impedance-pH monitoring and high-resolution manometry (HRM). Methods We retrospectively reviewed the impedance-pH data and HRM metrics in patients with refractory gastroesophageal reflux symptoms. Impedance-pH monitoring and manometric data were compared between 2 groups: ineffective esophageal motility (IEM) and normal motility. Results Forty-eight patients (30 males, mean age 54.5 years) were included (16 erosive esophagitis, 24 non-erosive reflux disease, and 8 functional heartburn), amongst which 24 subjects showed IEM, and others had normal motility. Number of patients who had a large break in the IEM group was significantly higher than that of normal motility patients. IEM group had more patients with weakly acid reflux and long term acid reflux than the normal group (P = 0.008, P = 0.004, respectively). There was no statistical difference in baseine impedance levels from z4 to z6 between the 2 groups (2911 ± 1160 Ω vs 3604 ± 1232 Ω, 2766 ± 1254 Ω vs 3752 ± 1439 Ω, 2349 ± 1131 Ω vs 3038 ± 1254 Ω, all P > 0.05). Acid exposure time, numbers of long term acid reflux and weakly acid reflux showed strong negative correlation with esophageal body motility and/or lower esophageal sphincter function. Conclusions IEM was associated more with acid exposure, abnormal weakly acid reflux, and long term acid reflux in RGERD patients. These data suggested the role of esophageal body dysmotility in the pathophysiological mechanisms of RGERD patients. PMID:27599539

Surgical treatment of gastroesophageal reflux has been thought to depend on the construction of a valve mechanism at the gastroesophageal junction (GEJ). Recently, a silicone prosthesis that does not construct a valve has been introduced, and in preliminary studies in the human, shown to be effective in the treatment of reflux. A precise mode of action has not been demonstrated for the prosthesis. This study was undertaken to investigate the mechanics of the prosthesis and determine its effectiveness in an animal model. Six canine gastroesophageal specimens were excised and the lower esophageal sphincter (LES) simulated by a rubber band placed around the GEJ at a tension calibrated to give 25 mmHg "sphincter" pressure. Circumferential silk ligatures of varying length were then placed on the stomach 3.0 cm distal to the GEJ. With no ligature, the LES opening pressure (LESOP) was 8.0 mmHg, varying to 17.0 mmHg with an 8.0 cm ligature. Further, 24 adult mongrel dogs were randomly divided into four equal groups: controls, circular myomectomy of the LES alone, myomectomy combined with fundoplication, and myomectomy combined with implantation of the silicone antireflux prosthesis. Evaluation included manometry, endoscopy, and histology. Although only the normal sphincter and fundoplication responded physiologically, the prosthesis was just as effective in preventing reflux, as evidenced by reducing acid exposure time of myomectomized dogs from 35.4% to 1.8%, and by preventing endoscopic esophagitis. It was concluded that the silicone antireflux prosthesis acts in the same fashion as the ligature in the model, by interrupting distraction of the LES by gastric wall tension. This concept is an effective method for raising LESOP, treating experimental gastroesophageal reflux, and eliminating the sequelae of reflux. Long-term evaluations of the prosthesis are required.

Background/Aims Available data about reflux patterns and symptom determinants in the gastroesophageal reflux disease (GERD) subtypes off proton pump inhibitor (PPI) therapy are lacking. We aimed to evaluate reflux patterns and determinants of symptom perception in patients with GERD off PPI therapy by impedance-pH monitoring. Methods We retrospectively reviewed the impedance-pH data in patients diagnosed as GERD based on results of impedance-pH monitoring, endoscopy and/or typical symptoms. The characteristics of acid and weakly acidic reflux were evaluated. Symptomatic and asymptomatic reflux were compared according to GERD subtypes and individual symptoms. Results Forty-two patients (22 males, mean age 46 years) were diagnosed as GERD (17 erosive reflux disease, 9 pH(+) non-erosive reflux disease [NERD], 9 hypersensitive esophagus and 7 symptomatic NERD). A total of 1,725 reflux episodes were detected (855 acid [50%], 857 weakly acidic [50%] and 13 weakly alkaline reflux [< 1%]). Acid reflux was more frequently symptomatic and bolus clearance was longer compared with weakly acidic reflux. In terms of globus, weakly acidic reflux was more symptomatic. Symptomatic reflux was more frequently acid and mixed reflux; these associations were more pronounced in erosive reflux disease and symptomatic NERD. The perception of regurgitation was related to acid reflux, while that of globus was more related to weakly acidic reflux. Conclusions In patients not taking PPI, acid reflux was more frequently symptomatic and had longer bolus clearance. Symptomatic reflux was more frequently acid and mixed type; however, weakly acidic reflux was associated more with globus. These data suggest a role for impedance-pH data in the evaluation of globus.

The classic diagnosis of Barret esophagus is based on the finding of three of more cm of distal esophagus covered by specialized columnar epithelium. However, at the present time, it is based on the presence of intestinal metaplasia in the junction of squamous-columnar mucosae. To assess the prevalence of Barret esophagus using endoscopic and pathological criteria in healthy subjects and in individuals with gastroesophageal reflux. One hundred thirty nine controls and 372 patients with symptoms of gastroesophageal reflux subjected to an upper gastrointestinal endoscopy were studied. Patients with Barret esophagus were classified as having a "mini Barret" when the pathological presence of intestinal metaplasia was the only finding. A "short Barret esophagus" was diagnosed when less than 3 cm were covered with fingerings of mucosal substitutions and "extensive Barret esophagus" when more than 3 cm of esophageal mucosa were substituted. Two percent of controls, 12.4% of patients with gastroesophageal reflux without esophagitis and 11.7% of such patients with esophagitis had intestinal metaplasia in the gastroesophageal junction. Patients with Barret esophagus were older than the rest of patients. "Short Barret esophagus" is six times more frequent than "extensive Barret esophagus". Esophageal erosions, peptic ulcers and stenosis were more frequent in patients with extensive Barret esophagus. The prevalence of dysplasia was similar in all types of Barret esophagus. Intestinal metaplasia was very infrequent in control patients. In subjects with gastroesophageal reflux, classic endoscopic diagnosis may miss up to 80% of patients with Barret esophagus. Thus, gastroesophageal junction biopsies must be obtained in all patients with symptoms of gastroesophageal reflux.

Gastroesophageal reflux disease affects more than 10% of the adult population. Most patients can be effectively treated with lifestyle changes and adequate acid-reducing therapy. However, about 10% of the patients remain symptomatic despite treatment and severe complications may develop. Interestingly, some of these complications seem to be a sort of defensive mechanism that may either alleviate the patient's symptoms or prevent developing further complications. In Barrett's esophagus, which can be unambigously considered as a complication of gastroesophageal reflux disease, reflux symptoms ruining the quality of life may significantly improve, since the metaplastic Barrett epithelium is much more resistent to gastric acid, than the normal epithelial lining of the esophagus. Furthermore, the motility disorders (hypertensive lower esophageal sphincter, achalasia, cricopharyngeal achalasia) and structural changes (Schatzki's ring, esophageal stricture, subglottic trachea stenosis), which develop as a complication of reflux may help to prevent aspiration that can cause new complaints and may lead to further complications.

Proton pump inhibitors are the most effective medical therapy for gastroesophageal reflux disease, but their onset of action may be slow. To assess the available literature regarding the efficacy of omeprazole/sodium bicarbonate in gastroesophageal reflux patients. A systematic review was conducted. A systematic literature search starting from 2000. Reviewed manuscripts concerning the effectiveness of omeprazole/sodium bicarbonate treatment in gastroesophageal reflux disease were reviewed and the data were extracted. Data were subsequently analyzed with descriptive statistics. This review included information of four studies. Two trials compared the efficacy of omeprazole/sodium bicarbonate versus omeprazole. One study compared the efficacy of once-daily morning or nighttime dosing. And another study compared omeprazole/sodium bicarbonate/alginate versus omeprazole. In total, there was no difference between omeprazole/sodium bicarbonate and omeprazole. However, there is a trend towards more sustained response and a greater proportion of patients with sustained total relief by 30 minutes with omeprazole/sodium bicarbonate. Omeprazole/sodium bicarbonate therapy is not more effective than omeprazole in the treatment of gastroesophageal reflux disease. However, data obtained suggest that it can have a more sustained response and sustained total relief.

Diagnosis and treatment of gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is a common disease with a prevalence as high as 10%-20% in the western world. The disease can manifest in various symptoms which can be grouped into typical, atypical and extra-esophageal symptoms. Those with the highest specificity for GERD are acid regurgitation and heartburn. In the absence of alarm symptoms, these symptoms can allow one to make a presumptive diagnosis and initiate empiric therapy. In certain situations, further diagnostic testing is needed to confirm the diagnosis as well as to assess for complications or alternate causes for the symptoms. GERD complications include erosive esophagitis, peptic stricture, Barrett’s esophagus, esophageal adenocarcinoma and pulmonary disease. Management of GERD may involve lifestyle modification, medical therapy and surgical therapy. Lifestyle modifications including weight loss and/or head of bed elevation have been shown to improve esophageal pH and/or GERD symptoms. Medical therapy involves acid suppression which can be achieved with antacids, histamine-receptor antagonists or proton-pump inhibitors. Whereas most patients can be effectively managed with medical therapy, others may go on to require anti-reflux surgery after undergoing a proper pre-operative evaluation. The purpose of this review is to discuss the current approach to the diagnosis and treatment of gastroesophageal reflux disease. PMID:25133039

Dyspepsia and gastroesophageal reflux disease (GERD): is there any correlation?

PubMed

Simadibrata, Marcellus

2009-10-01

Dyspepsia is a syndrome characterized by symptoms and signs of upper gastrointestinal tract and the adjacent organs. It is estimated that 25% of the community have symptoms of dyspepsia syndrome. One-third of patients who visit general physician practices are patients with dyspepsia syndrome; and half of patients who visit gastroenterologists are also patients with dyspepsia syndrome. Dyspepsia syndrome and gastroesophageal reflux disease (GERD) are very prevalent in the community throughout the world.Gastroesophageal reflux disease (GERD) is more and more commonly found in daily medical practice. Until now,the natural history of disease on GERD and dyspepsia is hardly understood, even though many scientists studied both conditions and there are frequently overlapping. In an individual, GERD and dyspepsia may occur simultaneously and therefore they are hardly to be discriminated.The management of GERD is performed in keeping with Indonesia and Asia Pacific consensus, life-style modification and administering the acid suppression agents (Proton pump inhibitor (drug of choice), H2-receptor antagonist, etc),prokinetic agents (Cisapride, domperidone, etc). Life-style modification shall be performed as follows, i.e. sleep with 30-45 degree elevated head or upper chest, do not avoid sour beverages, chocolate, coffee or alcohol, avoid fat and various fried foods, sour food, less stress, stop smoking, small but frequent feeding, etc. There is a correlation between dyspepsia syndrome and gastroesophageal reflux disease(GERD), particularly between the functional dyspepsia and non-erosive gastroesophageal reflux (NERD). More appropriate definition is necessary to differentiate the dyspepsia syndrome and GERD. Further studies are needed to establish distinct definition and criteria between dyspepsia syndrome and GERD.

The objective was to analyze the association of radiotherapy with gastroesophageal reflux as determinant of fistula related pathology, in voice prosthesis patients. Retrospective study. Sixty-one laryngectomy patients were enrolled between 2005 and 2012. All patients underwent phonatory rehabilitation with voice prosthesis, along with evidence of gastroesophageal reflux disease, for which proton pump inhibitors (PPIs) were prescribed. We analyzed the occurrence of fistula-related problems among patients who received postoperative radiotherapy and those patients who did not. We observed a higher rate of failure of speech rehabilitation in laryngectomy patients with gastroesphageal reflux: this occurred when they had a history of postoperative radiotherapy (45%) compared with patients who did not (17%) (P < 0.05), although all patients were treated with PPIs. Our results seem to confirm the importance of postoperative radiotherapy with gastroesophageal reflux for the determinism of fistula-related problems. Copyright © 2014 The Voice Foundation.

Gastroesophageal reflux disease lowers the quality of life and increases medical costs. Electroacupuncture has been used to ease symptoms and improve gastrointestinal motility in patients with gastroesophageal reflux disease. The main purposes of this study are to evaluate the efficacy and safety of this procedure. This is a protocol for a randomized, patient-blinded, assessor-blinded, sham-controlled trial. Sixty participants with symptoms of gastroesophageal reflux disease, who have previously undergone standard treatment, will be recruited from August 2015 at Kyung Hee University Korean Medicine Hospital. The participants will be allocated to either the electroacupuncture (n = 30) or the sham electroacupuncture group (n = 30); the allocation will be concealed from both the participants and the assessors. The EA group will undergo penetrating acupuncture at 18 fixed points and two optional points chosen using the pattern identification for gastroesophageal reflux disease. Electrical stimulation will be applied at some of the acupoints. The sham electroacupuncture group will undergo nonpenetrating acupuncture without electrical stimulation at 18 nonspecific points, each of which will be only 2 cm away from the true acupoints used in the electroacupuncture group. In both groups, the procedure will be performed using the Park device. The treatment will last for 6 weeks (with two sessions each week), and the outcome will be evaluated at baseline, 3 weeks, and 6 weeks. The primary outcome will be the proportion of responders with adequate symptom relief, whereas the secondary outcomes will comprise the results of the Nepean dyspepsia index; the Korean gastrointestinal symptom rating scale; the EQ-5D™; levels of gastrin, motilin, and inflammatory cytokines; the perceived stress scale; the qi-stagnation questionnaire; the patient global impression of change; and the spleen qi deficiency questionnaire.

Autonomic signs and symptoms could be of epileptic or nonepileptic origin, and the differential diagnosis depends on a number of factors which include the nature of the autonomic manifestations themselves, the occurrence of other nonictal autonomic signs/symptoms, and the age of the patient. Here, we describe twelve children (aged from ten months to six years at the onset of the symptoms) with Panayiotopoulos syndrome misdiagnosed as gastroesophageal reflux disease. Gastroesophageal reflux disease and Panayiotopoulos syndrome may represent an underestimated diagnostic challenge. When the signs/symptoms occur mainly during sleep, a sleep EEG or, if available, a polysomnographic evaluation may be the most useful investigation to make a differential diagnosis between autonomic epileptic and nonepileptic disorders. An early detection can reduce both the high morbidity related to mismanagement and the high costs to the national health service related to the incorrect diagnostic and therapeutic approaches. To decide if antiseizure therapy is required, one should take into account both the frequency and severity of epileptic seizures and the tendency to have potentially lethal autonomic cardiorespiratory involvement. In conclusion, we would emphasize the need to make a differential diagnosis between gastroesophageal reflux disease and Panayiotopoulos syndrome in patients with "an unusual" late-onset picture of GERD and acid therapy-resistant gastroesophageal reflux, especially if associated with other autonomic symptoms and signs.

Increased levels of anxiety and depression have been associated with esophageal hyperalgesia and an increased risk of gastroesophageal reflux disease (GERD). We investigated the effects of anxiety and depression on GERD symptoms and the perception of reflux episodes in a well-characterized group of patients. We performed a prospective study of 225 consecutive patients who had symptoms of GERD evaluated. Patients underwent ambulatory 24-hour pH impedance monitoring, and levels of anxiety and depression were assessed using the Hospital Anxiety and Depression Scale. GERD was diagnosed in 147 patients (78 patients had functional heartburn); 36 patients were hypersensitive to gastroesophageal reflux. Among patients with GERD, increased levels of anxiety were associated with more severe retrosternal pain and retrosternal burning. Furthermore, increased levels of anxiety and depression each were associated with lower scores of the mental component of quality of life questionnaire. Levels of anxiety or depression were not associated with the number of reflux symptoms reported during 24-hour pH impedance monitoring or with the number of symptoms associated with a reflux event. Among GERD patients with hypersensitivity to reflux, levels of anxiety and depression and decreases in quality of life were similar to those of other patients with GERD. Patients with functional heartburn had higher levels of anxiety than patients with GERD. In patients with GERD, increased levels of anxiety are associated with increased severity of retrosternal pain and heartburn and reduced quality of life. Patients with GERD with hypersensitivity to gastroesophageal reflux have similar levels of anxiety and similar quality-of-life scores as other patients with GERD. Copyright © 2015 AGA Institute.

To evaluate the agreement of multichannel intraluminal impedance-pH monitoring (MII-pHM) and gastroesophageal reflux scintigraphy (GES) for the diagnosis of gastroesophageal reflux disease. Seventy-five consecutive patients with suspected gastroesophageal reflux disease (GERD) underwent 24-h combined MII-pHM recording and one hour radionuclide scintigraphy during the course of the MII-pHM study. Catheters with 6 impedance channels and 1 pH sensor were placed transnasally. Impedance and pH data analysis were performed automatically and manually. For impedance monitoring, reflux was defined as a retrograde 50% drop in impedance, starting distally and propagating retrogradely to at least the next two more proximal measuring channels. Reflux index (RI, percentage of the entire record that esophageal pH is < 4.0) greater than 4.2% for pHM and number of refluxes more than 50 for 24 h for MII were accepted as positive test results. At scintigraphy, 240 frames of 15 seconds duration were acquired in the supine position. Gastroesophageal reflux was defined as at least one reflux episode in the esophagus. After scintigraphic evaluation, impedance-pH recordings and scintigraphic images were evaluated together and agreement between tests were evaluated with Cohen's kappa. Sufficient data was obtained from 60 (80%) patients (34 male, 56.7%) with a mean age of 8.7 ± 3.7 years (range: 2.5-17.3 years; median: 8.5 years). Chronic cough, nausea, regurgitation and vomiting were the most frequent symptoms. The mean time for recording of MII-pHM was 22.8 ± 2.4 h (range: 16-30 h; median: 22.7 h). At least one test was positive in 57 (95%) patients. According to diagnostic criteria, GERD was diagnosed in 34 (57.7%), 44 (73.3%), 47 (78.3%) and 51 (85%) patients by means of pHM, MII, GES and MII-pHM, respectively. The observed percentage agreements/κ values for GES and pHM, GES and MII, GES and MII-pHM, and MII and pHM are 48.3%/-0.118; 61.7%/-0.042; 73.3%/0.116 and 60

Gastroesophageal reflux disease (GERD) is prevalent worldwide, particularly in developed countries. It is estimated that the prevalence of GERD in the United States is approximately 20% and that it is increasing because of the epidemic of obesity. To review the pathophysiology, clinical presentation, diagnostic evaluation, and treatment of GERD. A search of PubMed was conducted for the years spanning 1985 to 2015 and included the following terms: heartburn, regurgitation, dysphagia, gastroesophageal reflux disease, cough, aspiration, laryngitis, GERD, GORD, endoscopy, manometry, pH monitoring, proton pump inhibitors, open fundoplication, and laparoscopic fundoplication. Only articles in English were included. Lifestyle modifications, proton pump inhibitors, and laparoscopic fundoplication are proven treatment modalities for GERD. Endoscopic procedures have not been proven as effective. A Roux-en-Y gastric bypass is the procedure of choice when GERD and morbid obesity coexist. Gastroesophageal reflux disease is a highly prevalent disease. Once the diagnosis has been established, the best results are obtained by a multidisciplinary team with the goal of individualizing treatment for patients.

Background The association between obesity and gastroesophageal reflux disease has a high incidence and may be present in half of obese patients with surgical indication. Bariatric operations can also induce reflux alone - differently from BMI factors - and its mechanisms are dependent on the type of procedure performed. Objective To perform a literature review comparing the two procedures currently most used for surgical treatment of obesity and analyze their relationship with the advent of pre-existing reflux disease or its appearance only in postoperative period. Method The literature was reviewed in virtual database Medline/PubMed, SciELO, Lilacs, Embase and Cochrane crossing the following MeSH descriptors: gastric bypass AND / OR anastomosis, Roux-en-Y AND / OR gastroesophageal reflux AND / OR gastroenterostomy AND / OR gastrectomy AND / OR obesity AND / OR bariatric surgery AND / OR postoperative period. A total of 135 relevant references were considered but only 30 were used in this article. Also was added the experience of the authors of this article in handling these techniques on this field. Conclusion The structural changes caused by surgical technique in vertical gastrectomy shows greater commitment of antireflux mechanisms predisposing the induction of GERD postoperatively compared to the surgical technique performed in the gastrointestinal Bypass Roux-en-Y.

Background The role of sexual activity on gastroesophageal reflux disease (GERD) is an under-recognized concern of patients, and one rarely assessed by physicians. Objective The objective of this article is to determine the influence of sexual activity on the intraesophageal acid exposure and acid reflux events in GERD patients. Methods Twenty-one patients with the diagnosis of GERD were prospectively enrolled. Intraesophageal pH monitoring was recorded for 48 hours with a Bravo capsule. All patients were instructed to have sexual intercourse or abstain in a random order two hours after the same refluxogenic dinner within two consecutive nights. Patients were requested to have sex in the standard “missionary position” and women were warned to avoid abdominal compression. The patients completed a diary reporting the time of the sexual intercourse and GERD symptoms. The percentage of reflux time and acid reflux events were compared in two ways: within 30 and 60 minutes prior to and after sexual intercourse on the day of sexual intercourse and in the same time frame of the day without sexual intercourse. Results Fifteen of 21 GERD patients were analyzed. The percentage of reflux time and number of acid reflux events did not show a significant difference within the 30- and 60-minute periods prior to and after sexual intercourse on the day of sexual intercourse and on the day without sexual intercourse, as well. Conclusion Sexual activity does not predispose to increased intraesophageal acid exposure and acid reflux events. Larger studies are needed to confirm our findings in patients who define reflux symptoms during sexual intercourse. PMID:25452843

Literature has addressed the increased prevalence of gastroesophageal reflux disease (GERD) in obstructive sleep apnea (OSA). Significant improvement of GERD has been found after OSA treatment. However, precise mechanisms underlying this correlation remain unclear. We examined the association between nocturnal gastroesophageal reflux (GER) and sleep events in patients with coexisting OSA and GERD. A case-crossover study among 12 patients with coexisting moderate-severe OSA and GERD was conducted. Participants underwent simultaneous polysomnography and esophageal impedance and pH monitoring. GER subtypes (ie, acid reflux, non-acid reflux) were defined as outcomes. Respective control time points were selected in all eligible control periods. Each sleep event was assessed individually. Estimated odds ratios (ORs) and 95% confidence intervals (CIs) were analyzed. A p-value of < 0.05 was considered significant. Patients were determined as moderate to severe OSA (respiratory disturbance index of 42.66 [±22.09]). There were a total of 50 GER episodes, 22 acid reflux and 28 non-acid reflux. Arousals and awakenings were significantly associated with subsequent GER events. The OR for GER following an arousal was 2.31 (95% CI 1.39-3.68; p < 0.001) and following an awakening was 3.71 (95% CI 1.81-7.63; p < 0.001). GER events were significantly less likely to occur after other respiratory events (OR 0.38 [95% CI 0.18-0.82]; p = 0.01). No sleep events followed GER events (p > 0.05). Both awakening and arousal appear to precipitate any subtype of GER events in patients with coexisting GERD and moderate to severe OSA. However, GER events were significantly less likely to occur after other respiratory events and did not appear to cause sleep-related events. Copyright © 2016 Elsevier B.V. All rights reserved.

Pharmacoeconomic issues of the treatment of gastroesophageal reflux disease.

Storr, M; Meining, A; Allescher, H D

Gastroesophageal reflux disease (GERD) is one of the most common diagnoses in a gastroenterologist's practice. Gastroesophageal reflux (GER) describes the retrograde movement of gastric contents through the lower oesophageal sphincter (LES) to the oesophagus. GER can occur physiologically and may be accompanied by symptoms. The introduction of endoscopes and ambulatory devices for continuous monitoring of oesophageal pH (24 h pH monitoring) has led to great improvement in the ability to diagnose reflux disease and reflux-associated complications. The development of pathological reflux and GERD can be attributed to many factors. Pathophysiology of GERD includes transient lower oesophageal sphincter relaxations (TLESRs), incompetent LES because of a decreased lower oesophageal sphincter pressure (LESP) and deficient or delayed oesophageal acid clearance. Uncomplicated GERD may be treated by modification of lifestyle and eating habits in an early stage of GERD. The various agents currently used for treatment of GERD include mucoprotective substances, antacids, H2-blockers, prokinetics and proton pump inhibitors (PPIs). Although these drugs are effective, they do not necessarily influence the underlying causes of the disease by improving the oesophageal clearance, increasing the LESP or reducing the frequency of TLESRs. The following article gives an overview regarding current concepts of the pathophysiology and pharmacological treatment of GERD stressing on pharmacoeconomic issues of the treatment and discusses the advantages and disadvantages for step-up and step-down therapy.

Novel therapeutics for gastro-esophageal reflux symptoms.

PubMed

Zerbib, Frank; Simon, Mireille

2012-09-01

Approximately 20-30% of patients with gastro-esophageal reflux symptoms report inadequate symptom relief while on proton-pump inhibitor therapy. The mechanisms involved are failure of the antireflux barrier (transient lower esophageal sphincter relaxations), high proximal extent of the refluxate, esophageal hypersensitivity and impaired mucosal integrity. Persisting acid or nonacid reflux can be demonstrated in 40-50% of cases, suggesting that there is room for antireflux therapy in these patients. New antireflux compounds have been shown to decrease the occurrence of transient lower esophageal sphincter relaxations. The most promising classes of compounds are GABA type B agonists and metabotropic glutamate receptor 5 antagonists, which can reduce both reflux episodes and symptoms, but the development of these compounds has been abandoned for either safety issues or lack of efficacy. Esophageal hypersensitivity and impaired mucosal integrity may prove to be relevant therapeutic targets in the future.

Objectives The aim of this study was to compare the different diagnostic approaches in detection of gastroesophageal reflux disease in children presented with symptoms suggesting gastroesophageal reflux disease. Methods The study design was cross sectional. The study retrospectively included all children who underwent combined multiple intraluminal impedance and pH (pH-MII) monitoring due to gastrointestinal and/or extraesophageal symptoms suggesting gastroesophageal reflux disease at University Children's Hospital in Belgrade, from July 2012 to July 2016. Results A total of 218 (117 boys/101 girls), mean age 6.7 years (range 0.06–18.0 years), met the inclusion criteria. Gastroesophageal reflux disease was found in 128 of 218 children (57.4%) by pH-MII and in 76 (34.1%) children by pH metry alone. Using pH-MII monitoring as gold standard, sensitivity of pH-metry was lowest in infants (22.9%), with tendency to increase in older age groups (reaching 76.4% in children ≥ 9 years). The sensitivity of pH-metry alone in children with extraesophageal symptoms was 38.1%, while the sensitivity of pH-metry in children with gastrointestinal symptoms was 63.8%. Reflux esophagitis was identified in 31 (26.1%) of 119 children who underwent endoscopy. Logistic regression analysis showed that best predictors of endoscopic reflux esophagitis are the longest acid episode (OR = 1.52, p<0.05) and DeMeester reflux composite score (OR = 3.31, p<0.05). The significant cutoff values included DeMeester reflux composite score ≥ 29 (AUC 0.786, CI 0.695–0.877, p<0.01) and duration of longest acid reflux ≥ 18 minutes (AUC 0.784, CI 0.692–0.875, p<0.01). Conclusions The results of our study suggested that compared with pH-metry alone, pH-MII had significantly higher detection rate of gastroesophageal reflux disease, especially in infants. Our findings also showed that pH-MII parameters correlated significantly with the endoscopically confirmed erosive esophagitis. PMID:29095882

Sixty-nine infants younger than 1 year of age, with symptoms of persistent vomiting, recurrent choking, apnea, persistent cough, or stridor, were evaluated for gastroesophageal reflux. All infants underwent extended intraesophageal pH monitoring for 16 to 24 hours as well as gastroesophageal scintigraphy with technetium 99m sulfur colloid to study the correlation between the two tests. Forty-eight infants exhibited reflux with extended pH monitoring whereas 46 infants showed reflux with scintigraphy. However, the diagnosis of reflux in individual patients by extended pH monitoring corresponded poorly with the diagnosis of reflux in the same patients by scintigraphy. Similarly, no correlation was observedmore » between extended pH monitoring and scintigraphy results, whether expressed as percent gastric emptying or as gastroesophageal reflux ratio. We conclude that extended pH monitoring and scintigraphy measure different pathophysiologic phenomena and detect reflux under different conditions. The ability of these tests to detect reflux may be complementary and they may be of greatest value when used together to enhance the sensitivity and specificity of the diagnostic evaluation. Extended pH monitoring and scintigraphy should not be used interchangeably to monitor gastroesophageal reflux.« less

This study is to determine the association of ambulatory pH monitoring (24hr pH) with symptoms of gastroesophageal reflux and its other investigations. The clinical and epidemiological profiles of subjects referred for reflux disorders are also studied. Symptoms or group of symptoms, profiles and prior investigations of 1259 consecutive pediatric subjects (with 1332 24hr pH studies performed) referred for evaluation of reflux disorders between 1988 and 2012 were retrospectively studied. Chi-square or fisher exact test was used for hypothesis testing, student t-test for the comparison of means and the Wilcoxon rank-sum test for comparing medians of continuous variables. Gastroesophageal reflux disease (GERD), defined as reflux causing major symptoms and complications, was diagnosed in 57.5% subjects of the total sample. Forty-three percent were girls and 56.7% were boys. The most common age group was between 4 months and 2 years (51.2%). Vomiting (64.4%) and irritability (74%) were the most common symptoms with the neurological conditions (23.2%) being the most frequent underlying condition. The parameters used in 24hr pH were significantly higher in those diagnosed with GERD (P < 0.0001). The prevalence of GERD was found to be significantly higher when both gastrointestinal and respiratory symptoms were present (P = 0.008) at 66.4% than when compared with gastrointestinal (56.5%) and respiratory (52.2%) symptoms in isolation. Symptoms alone were not reliable in diagnosing GERD. Only 57.5% had GERD among patients referred for reflux disorders. 24hr pH is reliable and should be considered routine in reflux disorders, as it identifies patients with pathologic reflux and avoids a needless surgery. © 2016 International Society for Diseases of the Esophagus.

Gastroesophageal reflux disease: recent advances and its association with sleep.

PubMed

Oh, Jung Hwan

2016-09-01

Gastroesophageal reflux disease (GERD) is prevalent in Asia as well as in Western countries. Sleep disturbance and breathing disorders during sleep are becoming increasingly prevalent, and they are commonly associated with GERD. The relationship between GERD and obstructive sleep apnea (OSA) is still questionable, and it has expanded to include Barrett's esophagus. Nocturnal gastroesophageal reflux (nGER) symptoms might be clinically important in the explanation of this association. The therapy for reflux symptoms has resulted in improved subjective sleep parameters and enhanced sleep quality, thus supporting a direct relationship between GERD and sleep disturbance. This review discusses the epidemiology of sleep disturbances in GERD patients; the causative relationship between GERD and OSA, even though it remains an area of controversy; and the possible role of nGER in sleep problems. It also provides an update on the current state of knowledge linking GERD and sleep. © 2016 New York Academy of Sciences.

Approximately 60% of patients presenting to dentists with erosive tooth wear have significant gastroesophageal reflux (GERD), despite minor reflux symptoms. No longitudinal studies of reflux-associated erosive tooth wear and of reflux characteristics have been reported to date. The aim of this study was to characterize the longitudinal course of GERD and of associated erosive tooth wear, as well as factors predictive of its progression, in a large group of patients. Seventy-two patients presenting to dentists with clinically significant erosive tooth wear and increased esophageal acid exposure by 24-h multichannel intraluminal pH-impedance measurement (MII-pH) were re-assessed clinically and by MII-pH after 1 year treatment with esomeprazole 20 mg twice-daily. Predictive factors for erosive tooth wear were assessed by logistic regression. At follow-up, no further progression in erosive tooth wear was observed in 53 (74%) of patients. The percentage of time with a pH < 4, the number of acid reflux episodes and the percentage of proximal esophageal reflux off-PPI did not change significantly after one year, but the number of weakly acidic reflux episodes decreased significantly in the large subgroup without progression. None of the baseline demographic, clinical, endoscopic or esophageal acid exposure characteristics were significantly associated with progression of erosive tooth wear at follow-up. In this longitudinal study in patients with erosive tooth wear and oligosymptomatic GERD receiving esomeprazole for one year, erosive tooth wear did not progress further in the majority of patients. Background acidic esophageal reflux exposure appeared stable over time, whereas weakly acidic exposure decreased significantly in patients without erosion progression. MII-pH measurements on-PPI and with healthy controls will be useful in the further elucidation of the causal role of reflux in erosive tooth wear.

The aim of this study was to determine the efficacy of pectin solution, which increases the viscosity of liquid nutrient, for prevention of gastro-esophageal reflux in comparison with half-solid nutrient. The subjects were 10 elderly patients undergoing percutaneous endoscopic gastrostomy feeding. Twenty-four-hour esophageal multichannel intraluminal impedance and pH testing was performed during intake of half-solid nutrient and a combination of pectin solution and liquid nutrient. During 4 h after delivery, there was no significant difference in the total number of gastro-esophageal reflux events between the feeding of the half-solid nutrient and the combination of pectin solution and liquid nutrient (5.7 ± 1.2 vs 5.3 ± 1.0/4 h). Acidic reflux after delivery of the half-solid nutrient was significantly more frequent than that after delivery of the combination of pectin solution and liquid nutrient (80.7% vs 60.4%, p = 0.018). The incidence of gastro-esophageal reflux reaching the upper portion of the esophagus tended to be higher during delivery of the half-solid nutrient than during delivery of the combination of pectin solution and liquid nutrient (47.4% vs 34.0%, p = 0.153). In conclusion, the usage of pectin solution combined with liquid nutrient is effective for preventing acidic gastro-esophageal reflux and gastro-esophageal reflux reaching the upper portion of the esophagus.

Chronic cough is one of the most common clinical problems and it may be secondary to different stimuli and diseases, including low-level physical and chemical stimulation of the esophageal-bronchial reflex, suggestive of cough-reflex hyperresponsiveness, in patients with gastroesophageal reflux; however, it is still debated whether gastroesophageal reflux could induce airway inflammation and acidification. The aim of this study was to investigate airway pH and cysteynil-leukotrienes (Cys-LTs) concentration (a marker of airway inflammation) in exhaled breath condensate (EBC). Patients with chronic cough and for which all known causes, excluding gastroesophageal reflux, had been investigated and ruled out, were enrolled in the study. All patients underwent 24 h pH monitoring, and EBC was collected to assess pH and Cys-LTs concentration. Forty-five patients were included in the study and those with gastroesophageal reflux had significantly lower EBC-pH and higher concentration of EBC-Cys-LTs. There was a linear inverse correlation between EBC-pH values and EBC-Cys-LTs logarithmically transformed, and a multivariate analysis confirmed that the only significant determinat variable of EBC-Cys-LTs was the presence of gastroesophageal reflux. This study adds knowledge on possible mechanisms related to chronic cough associated with gastroesophageal reflux, which seems to be strictly dependent on airway acidification and the production of Cys-LTs, therefore suggesting an underlying neurogenic inflammation with tachykinins involvement.

Gastric acid is a key factor in the pathophysiology of gastroesophageal reflux disease. A plausible mechanism by which the Helicobacter pylori infection might protect against reflux disease is by its propensity to produce atrophic gastritis. The aim of the study was to establish the influence of Helicobacter pylori infection on the occurrence of gastroesophageal reflux in patients with different stages of renal insufficiency. The examination was organized as a prospective, clinical study and involved 68 patients--33 patients with preterminal stage of renal failure and 35 patients with terminal renal insufficiency. Due to dyspeptic difficulties, in all the patients there was preformed upper esophagogastroscopy and Helicobacter pylori infection was found by ureasa test. The patients with preterminal renal insufficiency were significantly younger than patients with terminal renal failure (53.4 +/- 11.1 vs. 65.4 +/- 12.3 years; p = 0.014). There was found a statistically significant difference between the groups in Helicobacter pylori infection (p = 0.03), hiatal hernia (p = 0.008), gastroesophageal reflux disease (p = 0.007), and duodenal ulcer (p = 0.002). Using the multiple non-parametric correlative analysis there was confirmed a negative correlation between Helicobacter pylori infection and gastro-esophageal reflux disease (Kendal tauB = -0.523; p = 0.003) and hiatal hernia (Kendal tauB = 0.403; p = 0.021), while there was found a positive correlation between gastro-esophageal reflux disease and hiatal hernia (Kendal tauB = 0.350; p = 0.044). Helicobacter pylori infection is a significant protective parameter of the incidence of gastro-esophageal reflux disease in patients with both pre-terminal and terminal renal insufficiency.

Adenoid hypertrophy is a disease that mostly occurs among children of 3-5 years old. It is caused by repeated inflammation and infection of nasopharynx and its adjoin parts, or the adenoid itself, which will finally leads to pathological hyperplasia of adenoid. With so much information we have acquired about this disease, its specific mechanism remains unknown. In recent years, some researches have indicated that adenoid hypertrophy may have something to do with extra-gastroesophageal reflux, in which pepsin plays a very important role, and pepsin will do a series of pathological damages to the upper airway as it reaches the upper respiratory tract. Based on relative domestic and foreign literature, this paper attempts to make a review about the relationship between gastroesophageal reflux and adenoid hypertrophy.

To determine the relationship between baseline impedance levels and gastroesophageal reflux, we retrospectively enrolled 110 patients (54 men and 56 female; mean age, 51 ± 14 years) with suspected gastroesophageal reflux disease (GERD) who underwent 24-h multichannel intraluminal impedance and pH monitoring. Patients were stratified according to symptom (typical or atypical) and reflux types (acid reflux, nonacid reflux [NAR], or no abnormal reflux). Mean nocturnal baseline impedance (MNBI) were measured 3 cm (distal esophagus) and 17 cm (proximal esophagus) above the lower esophageal sphincter. Median distal esophageal MNBI was lower in the acid reflux group (1244 Ω; 647-1969 Ω) than in the NAR (2586 Ω; 1368-3666 Ω) or no abnormal reflux groups (3082 Ω; 2495-4472 Ω; all P < .05). Distal MNBI were negatively correlated with DeMeester score and acid exposure time. Atypical symptoms were more frequently associated with NAR than typical symptoms (P < .01). Among patients with positive symptom-association probability (SAP) for NAR, median proximal MNBI tended to be lower in patients with typical symptoms (median, 3013 Ω; IQR, 2535-3410 Ω) than in those with atypical symptoms (median, 3386 Ω; IQR, 3044-3730 Ω, P = .05). Thus, atypical GERD symptoms were more likely to be associated with NAR. The mucosal integrity of the proximal esophagus might be relatively impaired in GERD patients with typical symptoms for NAR.

Gastroesophageal reflux disease (GERD) is one of the most common problems treated by primary care physicians. Almost 20% of the population in the United States experiences occasional regurgitation, heartburn, or retrosternal pain because of GERD. Reflux disease is complex, and the physiology and pathogenesis are still incompletely understood. However, abnormalities of any one or a combination of the three physiologic processes, namely, esophageal motility, lower esophageal sphincter function, and gastric motility or emptying, can lead to GERD. There are many diagnostic and therapeutic approaches to GERD today, but more studies are needed to better understand this complex disease process. Copyright © 2015 Elsevier Inc. All rights reserved.

Endoscopic Options for Gastroesophageal Reflux: Where Are We Now and What Does the Future Hold?

Triadafilopoulos, George

2016-09-01

Early in the twenty-first century, novel endoscopic techniques were introduced for the management of gastroesophageal reflux disease, providing minimally invasive ways to eliminate pharmacologic acid inhibition and avoid the need for anti-reflux surgery. These techniques do not significantly alter the anatomy of the gastroesophageal junction, minimizing short- and long-term adverse effects, such as dysphagia and bloating. After extensive clinical testing, many endoscopic therapies were abandoned due to either lack of durable efficacy or unfavorable safety profile. Today, only four such therapies remain clinically available, each with variable levels of clinical validation and market penetration. This review will provide an assessment of these endoscopic therapies, highlighting their respective strengths and weaknesses and their present and future applicability to patients with gastroesophageal reflux disease.

To determine if the reflux finding score (RFS), a validated score for airway inflammation, correlates with gastroesophageal reflux measured by multichannel intraluminal impedance (MII) testing, endoscopy, and quality of life scores. We performed a prospective, cross-sectional cohort study of 77 children with chronic cough undergoing direct laryngoscopy and bronchoscopy, esophagogastroduodenoscopy, and MII testing with pH (pH-MII) between 2006 and 2011. Airway examinations were videotaped and reviewed by 3 blinded otolaryngologists each of whom assigned RFS to the airways. RFS were compared with the results of reflux testing (endoscopy, MII, symptom scores). An intraclass correlation coefficient was calculated for the degree of agreement between otolaryngologists' RFS. Receiver operating characteristic curves were created to determine the sensitivity of the RFS. Spearman correlation was calculated between the RFS and reflux measurements by pH-MII. The mean ± SD RFS was 12 ± 4. There was no correlation between pH-MII variables and mean RFS (|r| < 0.15). The concordance correlation coefficient for RFS between otolaryngologists was low (intraclass correlation coefficient = 0.32). Using pH-metry as a gold standard, the positive predictive value for the RFS was 29%. Using MII as the gold standard, the positive predictive value for the RFS was 40%. There was no difference in the mean RFS in patients with (12 ± 4) and without (12 ± 3) esophagitis (P = .9). There was no correlation between RFS and quality of life scores (|r| < 0.15, P > .3). The RFS cannot predict pathologic gastroesophageal reflux and an airway examination should not be used as a basis for prescribing gastroesophageal reflux therapies. Copyright © 2016.

The prevalence of gastroesophageal reflux disease (GERD) has been increasing worldwide, with proton pump inhibitor (PPI) administration the current mainstay therapy for affected individuals. However, PPI efficacy is insufficient especially for non-erosive reflux disease. Although it has been reported that prokinetic drugs improve GERD, their effects on esophageal function remain to be clearly investigated. In the present study, we evaluated the direct effects of acotiamide, a novel prokinetic agent for the treatment of functional dyspepsia, on esophageal motor function and gastroesophageal reflux. Ten adult healthy volunteers (average age 24 years, range 20-36 years; 7 males, 3 females) were enrolled. Esophageal body peristaltic contractions and lower esophageal sphincter (LES) pressure with and without acotiamide administration were recorded using high resolution manometry using a cross-over protocol. Total and acidic reflux levels for 24 h and during the postprandial period were also recorded using a multichannel intraluminal impedance and pH monitoring system. Data were analyzed blind by one observer. Acotiamide at a standard dose of 300 mg/day did not significantly stimulate esophageal motor function. Although the frequency of swallows with weak contraction tended to decrease with acotiamide administration, the difference as compared to no administration was not statistically significant. In addition, the drug neither decreased total or postprandial gastroesophageal acid/non-acid reflux events nor accelerated esophageal clearance time. Acotiamide, a novel gastrointestinal motility modulator, at a standard dose did not significantly affect esophageal motor functions or gastroesophageal reflux in healthy adults. Additional investigations with GERD patients are necessary to elucidate its clinical significance.

AIM: To study the prevalence of Barrett’s esophagus in Chinese and its correlation with gastroesophageal reflux. METHODS: This study was carried out in a large prospective series of 391 patients who had undergone upper endoscopy. The patients were divided into 3 groups according to the position of squamocolumnar junction (SCJ). Reflux esophagitis (RE) and its degree were recorded. Intestinal metaplasia (IM) in biopsy specimen was typed according to histochemistry and HE and alcian blue (pH2.5) staining separately. Results correlating with clinical, endoscopic, and pathological data were analysed. RESULTS: The prevalence of IM endoscopically appearing Long-segment Barrett’s Esophagus (LSBE) was 26.53%, Short-segment Barrett’s Esophagus (SSBE) was 33.85% and gastroesophageal junction (GEJ) was 34.00%. IM increased with age of above 40 years old and no difference was found between male and female. Twelve were diagnosed as dysplasia (7 low -grade, 5 high-grade), 16 were diagnosed as cardiac adenocarcinoma and 1 as esophageal adenocarcinoma. The more far away the SCJ moved upward above GEJ, the higher the prevalence and the more severe the RE were. CONCLUSION: There was no difference of the prevalence of IM in different places of SCJ, and IM increased with age of above 40 years old. It is important to pay attention to dysplasia in the distal esophagus and gastro-esophageal junction, and adenocarcinoma is more common in cardia than in esophagus. BE is a consequence of gastroesophageal reflux disease. PMID:15052695

Objective Clinically, patients with proton pomp inhibitor (PPI)-resistant gastro-esophageal reflux disease (GERD) are very challenging to treat. The aim of this study was to determine the rates of symptom relief and adverse events among PPI-resistant GERD patients that changed their therapy from a PPI to vonoprazan. Methods Patients with severe gastroesophageal reflux symptoms (total GERD-Q score ≥8) without endoscopic findings of mucosal breaks who changed their medication from a PPI to vonoprazan during a 12-week period from 2015 to 2016 at 2 hospitals were selected. The primary outcome was the self-reported relief of gastroesophageal reflux symptoms. The odds ratio (OR) for the improvement of symptoms was calculated based on an exact binomial distribution using a matched-pair analysis. The secondary outcome was the GERD-Q score and adverse events. Results Twenty-six patients (6 men) with a mean age of 67.5 years were analyzed. After the therapy was changed from a PPI to vonoprazan, 18 patients (69.2%) reported an improvement, 6 (23.1%) reported no change, and 2 (7.7%) reported an exacerbation of symptoms. A change in therapy was significantly associated with improved self-reported symptoms (OR 9.0, p<0.001). The mean total GERD-Q score during vonoprazan treatment was significantly lower than that during PPI therapy (11.96 vs. 8.92). There were no significant differences in the incidence of adverse events between the therapies. Conclusion Changing the medication from a PPI to vonoprazan was significantly associated with an improvement in gastroesophageal reflux symptoms. Vonoprazan is one of the most promising treatment options for patients with PPI-resistant GERD.

Gastroesophageal reflux disease is one of the commonest chronic conditions in the western world and its prevalence is increasing worldwide. The discovery of the acid pocket explained the paradox of acid reflux occurring more frequently in the postprandial period despite intragastric acidity being low due to the buffering effect of the meal. The acid pocket was first described in 2001 when it was detected as an area of low pH immediately distal to the cardia using dual pH electrode pull-through studies 15 minutes after a meal. It was hypothesized that there was a local pocket of acid close to the gastroesophageal junction that escapes the buffering effect of the meal, and that this is the source of postprandial acidic reflux. The presence of the acid pocket has been confirmed in other studies using different techniques including high-resolution pHmetry, Bravo capsule, magnetic resonance imaging, and scintigraphy. This review aims to describe what we know about the acid pocket including its length, volume, fluid constituents, and its relationship to the lower esophageal sphincter and squamocolumnar junction. We will discuss the possible mechanisms that lead to the formation of the acid pocket and examine what differences exist in patients who suffer from acid reflux. Treatments for reflux disease that affect the acid pocket will also be discussed.

Background Refractory gastroesophageal reflux-induced chronic cough (GERC) is difficult to manage. The purpose of the study is to evaluate the efficacy of a novel stepwise protocol for treating this condition. Methods A total of 103 consecutive patients with suspected refractory reflux-induced chronic cough failing to a standard anti-reflux therapy were treated with a stepwise therapy. Treatment commences with high-dose omeprazole and, if necessary, is escalated to subsequent sequential treatment with ranitidine and finally baclofen. The primary end-point was overall cough resolution, and the secondary end-point was cough resolution after each treatment step. Results High-dose omeprazole eliminated or improved cough in 28.1% of patients (n=29). Further stepwise of treatment with the addition of ranitide yielded a favorable response in an additional 12.6% (n=13) of patients, and subsequent escalation to baclofen provoked response in another 36.9% (n=38) of patients. Overall, this stepwise protocol was successful in 77.6% (n=80) of patients. The diurnal cough symptom score fell from 3 [1] to 1 [0] (Z=6.316, P=0.000), and the nocturnal cough symptom score decreased from 1 [1] to 0 [1] (Z=–4.511, P=0.000), with a corresponding reduction in the Gastroesophageal Reflux Diagnostic Questionnaire score from 8.6±1.7 to 6.8±0.7 (t=3.612, P=0.000). Conversely, the cough threshold C2 to capsaicin was increased from 0.49 (0.49) µmol/L to 1.95 (2.92) µmol/L (Z=–5.892, P=0.000), and the cough threshold C5 was increased from 1.95 (2.92) µmol/L to 7.8 (5.85) µmol/L (Z=–5.171, P=0.000). Conclusions Sequential stepwise anti-reflux therapy is a useful therapeutic strategy for refractory reflux-induced chronic cough. PMID:26904227

Overweight can be a risk factor for pathological gastroesophageal reflux or hiatal hernia. To study the prevalence of gastroesophageal reflux in patients with severe obesity. Sixty seven patients, 51 female, aged 17 to 56 years old with a body mass index over 35 kg/m2, were studied. An upper gastrointestinal endoscopy was performed in all, esophageal manometry was done in 32 and 24 h pH monitoring was done in 32 patients. Seventy nine percent of patients complained of heartburn and 66% of regurgitation. In 16 patients, endoscopy was normal. An erosive esophagitis was found in 33 patients, a short columnar epithelium in 12 and a Barret esophagus with intestinal metaplasia in six. Normal endoscopic findings and erosive esophagitis were present with a higher frequency in women. No association between the degree of obesity and esophageal lesions was observed. Lower esophageal sphincter pressure and abdominal length were significantly higher in subjects with a body mass index over 50 compared to those with a body mass index between 35 and 39.9 kg/m2. No differences were observed in 24 h pH monitoring. A high proportion of severely obese patients had symptoms and endoscopical findings of pathological gastroesophageal reflux.

Abstract To determine the relationship between baseline impedance levels and gastroesophageal reflux, we retrospectively enrolled 110 patients (54 men and 56 female; mean age, 51 ± 14 years) with suspected gastroesophageal reflux disease (GERD) who underwent 24-h multichannel intraluminal impedance and pH monitoring. Patients were stratified according to symptom (typical or atypical) and reflux types (acid reflux, nonacid reflux [NAR], or no abnormal reflux). Mean nocturnal baseline impedance (MNBI) were measured 3 cm (distal esophagus) and 17 cm (proximal esophagus) above the lower esophageal sphincter. Median distal esophageal MNBI was lower in the acid reflux group (1244 Ω; 647–1969 Ω) than in the NAR (2586 Ω; 1368–3666 Ω) or no abnormal reflux groups (3082 Ω; 2495–4472 Ω; all P < .05). Distal MNBI were negatively correlated with DeMeester score and acid exposure time. Atypical symptoms were more frequently associated with NAR than typical symptoms (P < .01). Among patients with positive symptom-association probability (SAP) for NAR, median proximal MNBI tended to be lower in patients with typical symptoms (median, 3013 Ω; IQR, 2535–3410 Ω) than in those with atypical symptoms (median, 3386 Ω; IQR, 3044–3730 Ω, P = .05). Thus, atypical GERD symptoms were more likely to be associated with NAR. The mucosal integrity of the proximal esophagus might be relatively impaired in GERD patients with typical symptoms for NAR.

Management of Gastroesophageal Reflux Disease.

Gyawali, C Prakash; Fass, Ronnie

Management of gastroesophageal reflux disease (GERD) commonly starts with an empiric trial of proton pump inhibitor (PPI) therapy and complementary lifestyle measures, for patients without alarm symptoms. Optimization of therapy (improving compliance and timing of PPI doses), or increasing PPI dosage to twice daily in select circumstances, can reduce persistent symptoms. Patients with continued symptoms can be evaluated with endoscopy and tests of esophageal physiology, to better determine their disease phenotype and optimize treatment. Laparoscopic fundoplication, magnetic sphincter augmentation, and endoscopic therapies can benefit patients with well-characterized GERD. Patients with functional diseases that overlap with or mimic GERD can also be treated with neuromodulators (primarily antidepressants), or psychological interventions (psychotherapy, hypnotherapy, cognitive and behavioral therapy). Future approaches to treatment of GERD include potassium-competitive acid blockers, reflux-reducing agents, bile acid binders, injection of inert substances into the esophagogastric junction, and electrical stimulation of the lower esophageal sphincter.

Refractory chronic cough due to gastroesophageal reflux: Definition, mechanism and management

PubMed Central

2015-01-01

Refractory chronic cough due to gastroesophageal reflux is a troublesome condition unresponsive to the standard medical anti-reflux therapy. Its underlying mechanisms may include incomplete acid suppression, non-acid reflux, transient lower esophageal sphincter relaxations and esophageal hypersensitivity. The diagnosis of this disorder depends on both the findings of multi-channel intraluminal impedance-pH monitoring and the subsequent intensified anti-reflux therapy. The strategies of pharmacological treatment for refractory chronic cough due to reflux include the optimization of proton pump inhibitors and add-on therapies with histamine H2 receptor antagonists, baclofen and gabapentin. However, the further study is needed to satisfy its management. PMID:26413488

Changes in the expression of mucin genes in the esophageal mucosa associated with uncomplicated gastro-esophageal reflux disease have not been evaluated even though such changes could be associated with reflux-induced mucosal damage. We therefore sought to identify reflux-induced changes in mucin gene expression using a cell line and biopsies from the esophageal mucosa in patients with and without reflux. MUC-1, MUC-3, MUC-4, and MUC-5AC gene expressions were investigated in the HET-1A cell line following exposure to acid (pH 4) and/or bile (120 muM of a bile salt milieu), and in esophageal mucosal biopsies from controls, subjects with non-erosive gastro-esophageal reflux, and subjects with reflux associated with ulcerative esophagitis (erosive). The mucosal biopsies were also evaluated for IL-6 mRNA expression (inflammatory marker) and CK-14 mRNA expression (mucosal basal cell layer marker). Gene expression was determined using real-time reverse transcriptase-polymerase chain reaction analysis. In the cell line studies, there were differences in mRNA levels for all of the evaluated mucins following treatment with either acid or the acid and bile combination. In the studies which evaluated tissue specimens, IL-6 and CK-14 mRNA levels increased according to degree of reflux pathology. The expression of MUC-1 and MUC-4 in mucosa from patients with erosive reflux was lower than in subjects without reflux and in patients with non-erosive reflux, whereas the expression of MUC-3 and MUC-5AC was increased (although these differences did not reach significance at p < 0.05). When mRNA expression data for tissue samples from all groups were combined, significant correlations were identified between IL-6 vs. CK-14 and IL-6 vs. MUC-3, MUC-3 vs. CK-14 and MUC-3 vs. MUC-5AC, and for MUC-1 vs. MUC-5AC. The correlation between IL-6 and CK-14 was also significant within the control and non-erosive reflux groups. The correlation between IL-6 and MUC-3 was significant within the

The most common extraesophageal manifestations of gastroesophageal reflux disease (GERD) include chronic cough, asthma and laryngitis. There are two mechanisms proposed to explain extraesophageal syndromes caused by GERD. The first one is a direct way via irritation and/or microaspiration and the second one is an indirect, vagally mediated way. The investigation of extraesophageal manifestations of GERD is difficult and the empirical therapy with proton pump inhibitors usually double dose for at least three months is still the most common approach.

To estimate esophageal and gastric pH values on an empty stomach and after stimulation of gastric secretion and gastric and duodenal motor-evacuatory activity in patients with gastroesophageal reflux disease (GERD) associated with pathological refluxes, such as gastroesophageal reflux (GER) and duodenogastroesophageal reflux (DGER). The observational cross-sectional study was conducted to investigate and compare the parameters of intraesophageal and intragastric pH metry and peripheral electrogastroenterography in 103 GERD patients with endoscopically positive distal reflux esophagitis in GER and DGER. The patients with GERD developed pathological esophageal refluxes (both GER and DGER) in various degrees of impaired gastric production, from anacidity to hyperacidity. The patients with predominant DGER were found to have gastric hyperacidity and normal acidity slightly less frequently than those with predominant GER. The patients with GERD developing in the presence of predominant GER had moderate gastric stasis with discoordinated antroduodenal propulsion resulting from hypomotor dyskinesia of the stomach and duodenum. When DGER was predominant in the patients with GERD, the signs of gastric stasis and duodenal hyperkinesia were concurrent with discoordinated antroduodenal and duodenojejunal propulsion. The specific features of the esophagogastroduodenal secretory and motor evacuatory disorders found create conditions for the pathological refluxes into the esophagus, which differ in the composition of refluxate.

To determine the correlation between asthma and hiatal hernia (HH) in patients with gastroesophageal reflux disease (GERD)-related asthma requiring laparoscopic anti-reflux surgery. One hundred and thirty-six GERD patients with medically refractory asthma with (80 patients) or without HH (56 patients) were enrolled. Gastroesophageal reflux disease was assessed by endoscopy, esophageal manometry, reflux monitoring and symptom questionnaires, and treated with laparoscopic Nissen fundoplication (LNF) or LNF with concomitant hiatal hernia repair (LNF-HHR). The outcome measures included patients' satisfaction and drug independence. The patients with HH had lower esophageal sphincters (P = .005) and higher DeMeester scores (P = .014) than those without HH. After an average follow-up of 24 months, symptom scores were significantly decreased from the preoperative values (P < .05). Compared to LNF, LNF-HHR showed a better improvement in both esophageal and asthmatic symptoms (P < .0001 and P = .016, respectively). The patients with GERD with asthma have a high prevalence of HH. The presence of HH maybe correlated with asthma and severe GERD. Actively treating HH not only improved reflux, but also controlled asthma symptoms. © 2017 John Wiley & Sons Ltd.

Gastroesophageal reflux disease is one of the most common comorbidities in patients with asthma. Gastroesophageal reflux disease can be linked to difficult-to-control asthma. Current management includes gastric acid suppression therapy and surgical antireflux procedures. The LINX® procedure is a novel surgical treatment for patients with gastroesophageal reflux disease refractory to medical therapy. To the best of our knowledge, we report the first case of successful treatment of refractory asthma secondary to gastroesophageal reflux disease using the LINX® procedure. Our patient was a 22-year-old white woman who met the American Thoracic Society criteria for refractory asthma that had remained poorly controlled for 5 years despite progressive escalation to step 6 treatment as recommended by National Institutes of Health-National Asthma Education and Prevention Program guidelines, including high-dose oral corticosteroids, high-dose inhaled corticosteroid plus long-acting β2-agonist, leukotriene receptor antagonist, and monthly omalizumab. Separate trials with azithromycin therapy and roflumilast did not improve her asthma control, nor did bronchial thermoplasty help. Additional consultations with two other university health systems left the patient with few treatment options for asthma, which included cyclophosphamide. Instead, the patient underwent a LINX® procedure after failure of maximal medical therapy for gastroesophageal reflux disease with the additional aim of improving asthma control. After she underwent LINX® treatment, her asthma improved dramatically and was no longer refractory. She had normal exhaled nitric oxide levels and loss of peripheral eosinophilia after LINX® treatment. Prednisone was discontinued without loss of asthma control. The only immediate adverse effects due to the LINX® procedure were bloating, nausea, and vomiting. LINX® is a viable alternative to the Nissen fundoplication procedure for the treatment of patients with

This investigation was undertaken to establish the prevalence and distribution of tooth wear in different groups of medically compromised children and to assess the possible influence of gastroesophageal reflux, dietary factors, and parafunctional activity. Four groups of children including twenty-one with cerebral palsy were clinically examined and had in-depth, structured interviews, including information on medical history, medication, gastroesophageal reflux, feeding and drinking habits, parafunctional activity, and tooth-brushing procedures. All the children with cerebral palsy also had twenty-four-hour gastroesophageal pH monitoring. Of the fifty-one children in total, twenty-five had moderate or severe levels of dental erosion. No statistically significant differences were found between the groups as far as dietary influences, feeding habits, and tooth-brushing procedures. There was a significant association, however, between gastroesophageal reflux and erosion. It is concluded that in children with cerebral palsy this reflux may be much more important in the etiology of tooth surface loss than the parafunctional activity, which has classically been regarded as the cause.

Gastroesophageal reflux disease (GERD) frequently occurs in association with chronic respiratory diseases although the casual link is not always clear. Several pathophysiological and experimental factors are considered to support a role for GERD in respiratory disease. Conversely, respiratory diseases and bronchodilator treatment can themselves exacerbate GERD. When cough or severe asthma is being investigated, GERD does not need to be systematically looked for and a therapeutic test with proton pump inhibitors is not always recommended. pH impedance monitoring is now the reference diagnostic tool to detect non acid reflux, a form of reflux for which proton pump inhibitor treatment is ineffective. Recent data have shown a potential role of GERD in idiopathic pulmonary fibrosis and bronchiolitis obliterans following lung transplantation, leading to discussions about the place of surgery in this context. However, studies using pH impedance monitoring are still needed to better understand and manage the association between GERD and chronic respiratory diseases. Copyright © 2015 SPLF.

This is mainly due to the heterogeneity of study designs. To explain a potential link, some pathophysiological anomaly has been proposed such as the altered pressure gradient between thorax and abdomen, the parasympathetic reflex, the heightened bronchial reactivity and chemical effects of microaspired gastric juice. An accurate diagnosis of asthma and GORD is pivotal in order to lead effective treatment and to reach a significant positive outcome, in terms of quality of life and respiratory function amelioration. Gastroenterological evaluation of GORD includes the empiric proton pump-inhibitors (PPIs) trial, the esophageal pH monitoring and endoscopic evaluation. Besides spirometric investigations, pulmonologist have more specific examens such as bronchoalveolar lavage and exhaled breath condensate. Actually, international recommendations regarding the management of asthma suggest the assessment of potential comorbidities, including the presence of GORD, mostly in children, only in patients with normal pulmonary functional tests with frequent respiratory symptoms, and in case of uncontrolled asthma. Symptomatic gastro-esophageal reflux patients should be treated, but those with uncontrolled asthma should not be treated with anti-reflux drugs unless they are symptomatic for reflux. This review explores the state of the art about the pathogenesis and the management of the relationship between asthma and GORD.

To determine the frequency of the use of proton-pump inhibitor therapy in patients with typical symptoms of gastroesophageal reflux disease and evaluate its risk factors. The cross-sectional study was conducted between June 2010 and February 2011 across 10 cities of Pakistan. Adult patients giving a current history of typical gastroesophageal reflux disease symptoms were included. Information on patient demography, medical history, family history, prescription patterns, lifestyle factors and dietary habits were collected. SPSS 18 was used for statistical analysis and descriptive statistics were used for the analysis of categorical and continuous variables. Of the 1010 patients enrolled, 954 (94.45%) formed the study population. Of them, 520 (54.5%) were men. The overall mean age was 41.9 +/- 12.5 years, and 439 (46%) had body mass index > or = 25 kg/m2. Further, 805 (84.4%) reported history of dyspepsia while 692 (72.5%) had gastroesophageal reflux disease during the preceding year. Family history of acid peptic disease was reported by 231 (24.2%) patients. Prior to consultation, 505 (52.9%) patients were on proton-pump inhibitors. Following consultation, 923 (96.8%) patients were prescribed proton-pump inhibitors, with omeprazole being the preferred choice in 577 (60.5%). Associated risk factors included regular use of nonsteroidal anti-inflammatory drugs in 355 (37.2%) and current smoking in 210 (22.0%). Consuming spicy meals was reported by 666 (70.0%). Nearly half the patients with typical gastroesophageal reflux disease symptoms were overweight, and a majority consumed spicy meals. Proton-pump inhibitors were widely prescribed, and omeprazole was the preferred choice of drug.

High-resolution manometry (HRM) has resulted in new revelations regarding the pathophysiology of gastro-esophageal reflux disease (GERD). The impact of new HRM motor paradigms on reflux burden needs further definition, leading to a modern approach to motor testing in GERD. Focused literature searches were conducted, evaluating pathophysiology of GERD with emphasis on HRM. The results were discussed with an international group of experts to develop a consensus on the role of HRM in GERD. A proposed classification system for esophageal motor abnormalities associated with GERD was generated. Physiologic gastro-esophageal reflux is inherent in all humans, resulting from transient lower esophageal sphincter (LES) relaxations that allow venting of gastric air in the form of a belch. In pathological gastro-esophageal reflux, transient LES relaxations are accompanied by reflux of gastric contents. Structural disruption of the esophagogastric junction (EGJ) barrier, and incomplete clearance of the refluxate can contribute to abnormally high esophageal reflux burden that defines GERD. Esophageal HRM localizes the LES for pH and pH-impedance probe placement, and assesses esophageal body peristaltic performance prior to invasive antireflux therapies and antireflux surgery. Furthermore, HRM can assess EGJ and esophageal body mechanisms contributing to reflux, and exclude conditions that mimic GERD. Structural and motor EGJ and esophageal processes contribute to the pathophysiology of GERD. A classification scheme is proposed incorporating EGJ and esophageal motor findings, and contraction reserve on provocative tests during HRM. © 2017 John Wiley & Sons Ltd.

To evaluate esophageal body motor contractions occurring during esophageal reflux in pediatric patients with gastro-esophageal reflux disease (GERD). Patients referred for the evaluation of GERD who were evaluated with combined 24-hour pH probe and esophageal manometry test (MP24) were included. Patients were separated into the following groups: Group C -- normal pH probe and normal EGD; Group 1 -- abnormal pH probe and normal EGD; and Group 2 -- abnormal pH probe and EGD with histologic esophagitis. Esophageal motor function during reflux episodes was analyzed. Twenty-five patients were included. All had a normal stationary esophageal manometry. Patients in Groups 1 and 2 had significantly more gastroesophageal reflux by pH probe than Group C (P < 0.01). During the MP24, patients in Group 1 and 2 had significantly fewer contractions per minute pre-, during, and post-GER (P < 0.05). There were significant differences in the number of isolated and prolonged contractions (>7 sec) during prolonged GERD episodes >5 minutes (P < 0.05). Children with GERD have a decreased number and abnormal esophageal body contractions with esophageal reflux. This suggests that children with GERD with and without esophagitis have impaired esophageal body acid clearance.

Esophageal pH monitoring is considered to be the gold standard for the diagnosis of gastroesophageal acid reflux. However, this method is very troublesome and considerably limits the patient's routine activities. Wireless pH monitoring was developed to avoid these restrictions. To compare the first 24 hours of the conventional and wireless pH monitoring, positioned 3 cm above the lower esophageal sphincter, in relation to: the occurrence of relevant technical failures, the ability to detect reflux and the ability to correlate the clinical symptoms to reflux. Twenty-five patients referred for esophageal pH monitoring and with typical symptoms of gastroesophageal reflux disease were studied prospectively, underwent clinical interview, endoscopy, esophageal manometry and were submitted, with a simultaneous initial period, to 24-hour catheter pH monitoring and 48-hour wireless pH monitoring. Early capsule detachment occurred in one (4%) case and there were no technical failures with the catheter pH monitoring (P = 0.463). Percentages of reflux time (total, upright and supine) were higher with the wireless pH monitoring (P < 0.05). Pathological gastroesophageal reflux occurred in 16 (64%) patients submitted to catheter and in 19 (76%) to the capsule (P = 0.355). The symptom index was positive in 12 (48%) patients with catheter pH monitoring and in 13 (52%) with wireless pH monitoring (P = 0.777). 1) No significant differences were reported between the two methods of pH monitoring (capsule vs catheter), in regard to relevant technical failures; 2) Wireless pH monitoring detected higher percentages of reflux time than the conventional pH-metry; 3) The two methods of pH monitoring were comparable in diagnosis of pathological gastroesophageal reflux and comparable in correlating the clinical symptoms with the gastroesophageal reflux.

Gastroesophageal reflux disease (GERD) is defined as a condition which develops when the reflux of gastric contents causes troublesome symptoms, impairs quality of life, or leads to mucosal damage or complications. There are two main phenotypic presentations of GERD, the erosive (ERD) and non-erosive reflux disease (NERD), with the latter one representing up to 70% of GERD spectrum. Moreover, patients with GERD can be clinically subdivided into two distinct syndromes: patients with esophageal and extraesophageal symptoms. The diagnosis of NERD should be supported by the evidence that symptoms are due to reflux episodes on the basis of an excess of acid into the esophagus or a positive correlation between symptoms and acid and/or weakly acidic reflux episodes as evidenced by 24-hour impedance-pH monitoring. Patients with normal esophageal acid exposure and no correlation between heartburn and any kind of chemical reflux are considered affected by functional heartburn and do not pertain to the realm of NERD. They do not usually respond to PPI therapy as further empirical criterion and are included in the large group of functional digestive disorders with the expression of altered generation or perception of symptoms at the esophageal level and can often overlap with functional dyspepsia and irritable bowel syndrome.

Chronic cough affects more than 70 percent of patients with Idiopathic Pulmonary Fibrosis and causes significant morbidity. Gastroesophageal reflux is the cause of some cases of chronic cough; and also has a postulated role in the aetiology of Idiopathic Pulmonary Fibrosis. A high prevalence of acid; and more recently non-acid, reflux has been observed in Idiopathic Pulmonary Fibrosis cohorts. Therefore, gastroesophageal reflux may be implicated in the pathogenesis of cough in Idiopathic Pulmonary Fibrosis. Eighteen subjects with Idiopathic Pulmonary Fibrosis underwent 24-hour oesophageal impedance and cough count monitoring after the careful exclusion of causes of chronic cough other than gastroesophageal reflux. All 18 were then treated with high dose acid suppression therapies. Fourteen subjects underwent repeat 24-hour oesophageal impedance and cough count monitoring after eight weeks. Total reflux and acid reflux frequencies were within the normal range in the majority of this cohort. The frequencies of non-acid and proximal reflux events were above the normal range. Following high dose acid suppression therapy there was a significant decrease in the number of acid reflux events (p = 0.02), but an increase in the number of non-acid reflux events (p = 0.01). There was no change in cough frequency (p = 0.70). This study confirms that non-acid reflux is prevalent; and that proximal oesophageal reflux occurs in the majority, of subjects with Idiopathic Pulmonary Fibrosis. It is the first study to investigate the effect of acid suppression therapy on gastroesophageal reflux and cough in patients with Idiopathic Pulmonary Fibrosis. The observation that cough frequency does not improve despite verifiable reductions in oesophageal acid exposure challenges the role of acid reflux in Idiopathic Pulmonary Fibrosis associated cough. The finding that non-acid reflux is increased following the use of acid suppression therapies cautions against the widespread use

AIM OF THE REVIEW AND METHODS: This review brings together information on the treatment of gastroesophageal reflux disease. Published manuscripts were identified from Medline. The articles were then screened for relevance prior to inclusion in the review. Up to 40% of people in Western countries are estimated to regularly experience heartburn, the most characteristic symptom of gastroesophageal reflux disease (GERD). Treatment options available for GERD range from over-the-counter (OTC) antacids to proton pump inhibitors (PPIs) and anti-reflux surgery. Many patients self-medicate with OTC medications such as antacids and low-dose histamine H2-receptor antagonists (H2RA) to relieve episodic or food-related symptoms of GERD, and may not seek medical advice unless symptoms persist or worsen. However, GERD is a chronic disease that frequently affects health-related quality of life and, if not properly managed, the complications of GERD may include erosive oesophagitis (EO), Barrett's oesophagus and adenocarcinoma. Adequate control of acid secretion is key to the successful treatment of the condition. OTC medications provide effective symptom relief to about one quarter of patients suffering from GERD. H2RAs can also provide effective symptomatic relief, particularly in patients with milder GERD, but become less-effective over time. PPIs are the agents of choice for the suppression of gastric acid production and have become the mainstay of therapy for acid-related diseases. PPIs produce significantly faster and more complete symptomatic relief, significantly faster and more complete healing of erosive GERD compared with H2RAs and are also significantly more effective at preventing relapse of EO. There are a number of existing guidelines for the treatment of GERD. Recommendation for initial therapy consist of general measures, such as lifestyle advice in combination with antacids and/or alginates. When general measures fail, the next step is empirical therapy.

Gastroesophageal reflux disease (GERD) is a highly prevalent gastrointestinal disorder. Proton pump inhibitors have profoundly revolutionized the treatment of GERD. However, several areas of unmet need persist despite marked improvements in the therapeutic management of GERD. These include the advanced grades of erosive esophagitis, nonerosive reflux disease, maintenance treatment of erosive esophagitis, refractory GERD, postprandial heartburn, atypical and extraesophageal manifestations of GERD, Barrett’s esophagus, chronic protein pump inhibitor treatment, and post-bariatric surgery GERD. Consequently, any future development of novel therapeutic modalities for GERD (medical, endoscopic, or surgical), would likely focus on the aforementioned areas of unmet need. PMID:26130628

To investigate the effect of percutaneous endoscopic gastrostomy (PEG) on gastroesophageal reflux (GER) in mechanically-ventilated patients. In a prospective, randomized, controlled study 36 patients with recurrent or persistent ventilator-associated pneumonia (VAP) and GER > 6% were divided into PEG group (n = 16) or non-PEG group (n = 20). Another 11 ventilated patients without reflux (GER < 3%) served as control group. Esophageal pH-metry was performed by the "pull through" method at baseline, 2 and 7 d after PEG. Patients were strictly followed up for semi-recumbent position and control of gastric nutrient residue. A significant decrease of median (range) reflux was observed in PEG group from 7.8 (6.2 - 15.6) at baseline to 2.7 (0 - 10.4) on d 7 post-gastrostomy (P < 0.01), while the reflux increased from 9 (6.2 - 22) to 10.8 (6.3 - 36.6) (P < 0.01) in non-PEG group. A significant correlation between GER (%) and the stay of nasogastric tube was detected (r = 0.56, P < 0.01). Gastrostomy when combined with semi-recumbent position and absence of nutrient gastric residue reduces the gastroesophageal reflux in ventilated patients.

Dietary guideline adherence for gastroesophageal reflux disease

2014-01-01

Background Gastroesophageal reflux disease (GERD) is the most common gastrointestinal disease, and the cost of health care and lost productivity due to GERD is extremely high. Recently described side effects of long-term acid suppression have increased the interest in nonpharmacologic methods for alleviating GERD symptoms. We aimed to examine whether GERD patients follow recommended dietary guidelines, and if adherence is associated with the severity and frequency of reflux symptoms. Methods We conducted a population-based cross-sectional study within the Kaiser Permanente Northern California population, comparing 317 GERD patients to 182 asymptomatic population controls. All analyses adjusted for smoking and education. Results GERD patients, even those with moderate to severe symptoms or frequent symptoms, were as likely to consume tomato products and large portion meals as GERD-free controls and were even more likely to consume soft drinks and tea [odds ratio (OR) = 2.01 95% confidence interval (CI) 1.12-3.61; OR = 2.63 95% CI 1.24-5.59, respectively] and eat fried foods and high fat diet. The only reflux-triggering foods GERD patients were less likely to consume were citrus and alcohol [OR = 0.59; 95% CI: 0.35-0.97 for citrus; OR = 0.41 95% CI 0.19-0.87 for 1 + drink/day of alcohol]. The associations were similar when we excluded users of proton pump inhibitors. Conclusions GERD patients consume many putative GERD causing foods as frequently or even more frequently than asymptomatic patients despite reporting symptoms. These findings suggest that, if dietary modification is effective in reducing GERD, substantial opportunities for nonpharmacologic interventions exist for many GERD patients. PMID:25125219

Abstract Background: Gastroesophageal pathologies are common and multifactorial in patients with type 1 diabetes (T1DM). The evaluation with endoscopy and 24 h pH esophageal monitoring is expensive and not always available in all medical centers, especially in developing countries so more cost-effective algorithms for diagnosis are required. Clinical questionnaires are easy to apply but its utility for gastroesophageal reflux disease screening in patients with long standing T1DM must be analyzed. Objective: To evaluate the utility of the FSSG and Carlsson-Dent (CDQ) questionnaires to detect the frequency of gastroesophageal reflux disease in patients with T1DM. Methods: Analytic cross-sectional study, included 54 randomly selected patients from the T1DM clinic in our hospital. Before their routine evaluation, were asked to answer FSSG and CDQ questionnaires, classifying them as positive with a score >8 or >4, respectively. we associated and compared the clinical and biochemical characteristics between patients with or without gastroesophageal reflux detected through questionnaires. Results: Median age was 29 years (22-35), 67% were female (median of 16 years from diagnosis). In 39% of the patients FSSG was positive, CDQ was positive in 28%. A total of 71% of patients were taking medications to treat non-specific gastric symptoms. The concordance between questionnaires was 65% (p: <0.001). Those patients with tobacco consumption as well as those with poor glycemic control were more likely to score positive in either questionnaire. Conclusions: Patients T1DM had a high prevalence of gastroesophageal reflux disease. In those patients FSSG questionnaire detected a higher number of patients in comparison with CDQ. PMID:29213156

Gastroesophageal reflux (GER) is one of the most common causes of chronic cough, and chronic cough due to GER represents a subtype of GER-related diseases. Gastroesophageal reflux-induced chronic cough (GERC) can be divided into two subgroups based on the pH of the GER. Nonacid GERC is less common than acid GERC, and its diagnosis and treatment strategy have not been standardized. However, nonacid GERC usually presents with its unique set of characteristics and features upon diagnosis and treatment in the clinic. Although the underlying molecular mechanism of nonacid GERC is not fully understood, it is considered to be associated with reflux theory, reflex theory and airway hypersensitivity. Multi-channel intraluminal impedance combined with pH monitoring is a promising new technique that can detect both acid and nonacid reflux, and our findings as well as those of others have shown its usefulness in diagnosing nonacid GERC. Development of new diagnostic techniques has led to an increased rate of nonacid GERC diagnosis. We summarize our experience in the diagnosis and treatment of nonacid GERC and provide a guide for future therapeutic approaches. PMID:26759577

Proton Pump Inhibitors in Gastroesophageal Reflux Disease: Friend or Foe.

PubMed

Gyawali, C Prakash

2017-09-01

Proton pump inhibitor (PPI) use in gastroesophageal reflux disease (GERD) has been redefined, in light of recent advances highlighting GERD phenotypes that respond to PPIs, and fresh revelations of potential risks of long-term PPI therapy. Erosive esophagitis predicts excellent response to PPI therapy, but non-erosive reflux disease (NERD) with abnormal reflux parameters on ambulatory reflux monitoring also demonstrates a similar response. In contrast, response is suboptimal in the absence of abnormal reflux parameters. In this setting, if an alternate appropriate indication for PPI therapy does not coexist, risks may outweigh benefits of PPI therapy. Adverse events from long-term PPI therapy continue to be reported, most based on association rather than cause-and-effect. Appropriate indications need to be established before embarking on long-term PPI therapy. Future research will define true risks of long-term PPI therapy, and develop alternate management options for acid peptic diseases.

Gastroesophageal reflux disease (GERD) is an emerging disease, and can impair quality of life and sleep. This study aimed to investigate whether GERD patients with different timings of reflux symptoms have different clinical characteristics. This study prospectively enrolled individuals who underwent upper gastrointestinal endoscopy during a health checkup. Each participant completed all questionnaires including Reflux Disease Questionnaire, Nighttime GERD questionnaire, Pittsburg Sleep Quality Index, Taiwanese Depression Questionnaire, and State-Trait Anxiety Inventory. Combined reflux was defined as the timing of reflux symptoms occurring at both daytime and nighttime. A total of 2604 participants were enrolled. Of them, 651 symptomatic GERD patients, according to the Reflux Disease Questionnaire score, were recruited for final analysis. Of them, 224 (34.4%) had erosive esophagitis on endoscopy. According to the timing of reflux symptoms, 184 (28.3%) were assigned to the daytime reflux group, 71 (10.9%) to the nighttime reflux group, and 396 (60.8%) to the combined reflux group. In post hoc analysis, the combined reflux group had a significantly higher Reflux Disease Questionnaire score than the daytime reflux group (p < 0.0001). Combined and nighttime reflux groups had higher body mass index and longer duration (> 12 years) of education than the daytime reflux group (p < 0.05). There was no difference in Pittsburg Sleep Quality Index, Taiwanese Depression Questionnaire, and State-Trait Anxiety Inventory scores among three groups. GERD patients with combined daytime and nighttime reflux of have more troublesome symptoms than those with daytime reflux. GERD patients with different timings of reflux symptoms have different clinical characteristics in terms of body mass index and duration of education, but not in terms of esophageal inflammation, quality of sleep, and psychosocial status.

To compare the cost-effectiveness of therapy of gastroesophageal reflux disease with esomeprazole and other proton pump inhibitors (PPIs) in Poland. Studies comparing esomeprazole with other PPIs in the treatment of erosive esophagitis, non-erosive reflux disease and gastroesophageal reflux disease maintenance therapy were systematically reviewed. 9 randomized clinical trials were selected, meta-analyses were conducted. Cost data derived from Polish Ministry of Health and Pharmacies in Wroclaw. In the treatment of erosive esophagitis esomeprazole was significantly more effective than other PPIs. Both for 4- and 8-week therapy respective incremental cost-effectiveness ratio values were acceptably low. Differences in effectiveness of non-erosive reflux disease therapy were not significant. The replacement of pantoprazole 20 mg with more effective esomeprazole 20 mg in the 6-month maintenance therapy was associated with a substantially high incremental cost-effectiveness ratio.

Little data exists about esophageal body dysmotility and reflux patterns in refractory gastroesophageal reflux disease (RGERD) patients off therapy. We aimed to evaluate effects of esophageal body dysmotility on reflux parameters in RGERD patients by combining impedance-pH monitoring and high-resolution manometry (HRM). We retrospectively reviewed the impedance-pH data and HRM metrics in patients with refractory gastroesophageal reflux symptoms. Impedance-pH monitoring and manometric data were compared between 2 groups: ineffective esophageal motility (IEM) and normal motility. Forty-eight patients (30 males, mean age 54.5 years) were included (16 erosive esophagitis, 24 non-erosive reflux disease, and 8 functional heartburn), amongst which 24 subjects showed IEM, and others had normal motility. Number of patients who had a large break in the IEM group was significantly higher than that of normal motility patients. IEM group had more patients with weakly acid reflux and long term acid reflux than the normal group ( P = 0.008, P = 0.004, respectively). There was no statistical difference in baseine impedance levels from z4 to z6 between the 2 groups (2911 ± 1160 Ω vs 3604 ± 1232 Ω, 2766 ± 1254 Ω vs 3752 ± 1439 Ω, 2349 ± 1131 Ω vs 3038 ± 1254 Ω, all P > 0.05). Acid exposure time, numbers of long term acid reflux and weakly acid reflux showed strong negative correlation with esophageal body motility and/or lower esophageal sphincter function. IEM was associated more with acid exposure, abnormal weakly acid reflux, and long term acid reflux in RGERD patients. These data suggested the role of esophageal body dysmotility in the pathophysiological mechanisms of RGERD patients.

Background/Aims In a previous issue published in Gut and Liver, we found that erosive changes in the esophagogastroduodenal mucosa were strongly correlated with increased levels of volatile sulfur-containing compounds (VSC), suggesting that halitosis could be a symptom reflecting the erosive status of the upper gut mucosa. Together with other studies showing a possible association between halitosis and gastroesophageal reflux disease (GERD), under the premise that halitosis could be one of extraesophageal manifestations of erosive GERD (ERD), we investigated the significance of Halimeter ppb levels on ERD compared to non-erosive gastroesophageal reflux disease (NERD). Methods Subjects were assigned to the NERD group if there was no evidence of esophageal erosive changes on endoscopy, despite reflux symptoms, and to the ERD group if they had GERD A, B, C, or D (according to the Los Angeles classification). The VSC levels were measured in all patients with either a Halimeter (before endoscopy) or by gas chromatography of the gastric juices aspirated during endoscopy. Results The VSC level differed significantly between the NERD and ERD groups (p<0.0001), suggesting that this can be used to discriminate between NERD and ERD. However, the VSC level did not differ significantly with the severity of GERD. Even though hiatal hernia and a body mass index of >24 kg/m2 was significantly associated with ERD, there was no correlation with Halimeter ppb levels. Minimal-change lesions exhibited the highest VSC levels, signifying that minimal change lesions can be classified as ERD based on our finding that halimeter ppb levels were descrimitive of erosive change. Conclusions Erosive changes in the esophageal mucosa were strongly associated with VSC levels, supporting the hypothesis that halitosis can be a potential biomarker for the discrimination between ERD and NERD, reflecting the presence of erosive change in the lower esophagogastric junction.

Advanced lung disease is associated with gastroesophageal reflux disease (GERD). The thoracoabdominal pressure gradient (TAPG) facilitates gastroesophageal reflux, but the effects of TAPG on gastroesophageal reflux in patients with pulmonary disease have not been well defined. Patients diagnosed with end-stage lung disease are expected to have the most extreme derangement in respiratory mechanics. The aim of this study is to explore the relationship between TAPG and reflux in lung transplant (LTx) candidates. We reviewed LTx recipients who underwent pretransplant esophageal high-resolution manometry and a 24-hour pH study. Patients were excluded if they were undergoing redo LTx, had manometric hiatal hernia, or had previously undergone foregut surgery. TAPG was defined as the intra-abdominal pressure minus the intrathoracic pressure during inspiration. Adjusted TAPG was calculated by the TAPG minus the resting lower esophageal sphincter (LES) pressure (LESP). Twenty-two patients with normal esophageal function tests (i.e., normal esophageal motility with neither manometric hiatal hernia nor pathological reflux on 24-hour pH monitoring) were selected as the pulmonary disease-free control group. In total, 204 patients underwent LTx between January 2015 and December 2016. Of these, 77 patients met inclusion criteria. We compared patients with obstructive lung disease (OLD, n = 33; 42.9%) and those with restrictive lung disease (RLD, n = 42; 54.5%). 2/77 patients (2.6%) had pulmonary arterial hypertension. GERD was more common in the RLD group than in the OLD group (24.2% vs. 47.6%, P = 0.038). TAPG was similar between the OLD group and the controls (14.2 vs. 15.3 mmHg, P = 0.850); however, patients in the RLD group had significantly higher TAPG than the controls (24.4 vs. 15.3 mmHg, P = 0.002). Although TAPG was not correlated with GERD, the adjusted TAPG correlated with reflux in all 77 patients with end-stage lung disease (DeMeester score, rs = 0.256, P�

Gastroesophageal reflux (GER) symptoms are common in pregnancy. It often manifests for the first time in pregnancy during the first three months and ceases after delivery. To study the prevalence of gastroesophageal reflux in each of the three trimesters by follow-up of pregnant women. To examine the association between dietary factors and GER in pregnancy. This was a prospective hospital-based study. Sixty four pregnant women in their first trimester attending an antenatal clinic were interviewed for symptoms of GER and for dietary details and followed up until term and delivery. Fifty women (83.4%) experienced either heartburn or regurgitation during pregnancy. GER was commoner in primi-gravida (69.3%) and 50% remained symptomatic until term. Regurgitation was more common than heartburn and was often associated with nausea/vomiting. Women with an antenatal history of GERD had 3.79 times the odds of developing symptoms in the third trimester. There was no difference in weight gain in those with and without GER. Spicy food significantly increased the risk of heartburn and green vegetables were protective. The incidence of GERD decreased over three trimesters. Weight gain did not increase the prevalence of GERD. Spicy food aggravated while green vegetables protected against GERD.

Background Postprandial proximal gastric acid pocket (PPGAP) plays important roles in gastroesophageal reflux disease (GERD). In this study, we analyzed the characteristics of PPGAP in GERD. Material/Methods There were 17 normal participants and 20 GERD patients who completed a gastroesophageal reflux disease questionnaire (GerdQ) and underwent a gastroscopy, a high-resolution manometry, an esophageal 24-hour pH monitoring, and a station pull-through pH monitoring to assess their symptomatic degree, endoscopic change, acid exposure, and PPGAP. Results PPGAP was present in all participants. Compared with normal participants, the PPGAP in GERD patients was significantly different, thus the disappearing time was significantly later (p<0.001), the lasting time was significantly longer (p<0.001), the length was significantly longer (p<0.001), and the lowest pH and the mean pH were significantly lower (p<0.001). The length of PPGAP in GERD patients was positively correlated with GerdQ score (p<0.05). The disappearing time, the lasting time, and the length of PPGAP in GERD patients was positively correlated with the DeMeester score (p<0.01). The lowest pH and the mean pH of PPGAP in GERD patients was negatively correlated with the DeMeester score (p<0.001). Conclusions PPGAP was generally present. PPGAP in GERD patients had characteristics of long time period, long length, and high acidity. Its length was positively correlated with subjective symptomatic degree. Its period, length, and acidity were positively correlated with the objective acid exposure. PPGAP seems to be the originator of acid reflux events and plays important roles in GERD. PMID:29309401

The aim of this study was to explore the recent advances in diagnosis and treatment of gastroesophageal reflux disease (GERD). Previous studies were searched using the terms "gastroesophageal reflux disease" and "diagnosis" or "treatment" in Medline and Pubmed. Articles that were not published in the English language, manuscripts without an abstract, reviews, meta-analysis, and opinion articles were excluded from the review. After a preliminary screening, all of the articles were reviewed and synthesized to provide an overview of the contemporary approaches to GERD. GERD has a variety of symptomatic manifestations, which can be grouped into typical, atypical and extra-esophageal symptoms. Those with the highest specificity for GERD are acid regurgitation and heartburn. In the absence of other alarming symptoms, these symptoms allow one to make a presumptive diagnosis of GERD and initiate empiric therapy. GERD-associated complications include erosive esophagitis, peptic stricture, Barrett's esophagus, esophageal adenocarcinoma and pulmonary disease. Management of GERD may involve lifestyle modifications, medical and surgical therapy. Medical therapy involves acid suppression, which can be achieved with antacids, histamine-receptor antagonists or proton-pump inhibitors. Whereas most patients can be effectively managed with medical therapy, others may go on to require anti-reflux surgery after undergoing a proper pre-operative evaluation. The management of this disease requires a complex approach. Maintenance therapy of GERD after using anti-secretory drugs should be continuously monitored. © Acta Gastro-Enterologica Belgica.

This study aims to determine whether successful laparoscopic fundoplication for gastroesophageal reflux disease (GERD) can improve the control of hypertension. We conducted an observational study of GERD patients with hypertension. The esophageal and gastroesophageal symptoms of these patients were successfully treated with laparoscopic fundoplication, as measured by the reduced GERD symptoms and proton pump inhibitor consumption. A hypertension control scale was used to classify the use of antihypertensive medications and the quality of blood pressure control before and after anti-reflux surgery.Wilcoxon signed-ranks test was used for the statistical analyses. Seventy GERD patients were included in the analysis and followed up for a mean period of 3.5 ± 1.4 years. Prior to surgery, all participating patients were taking at least one class of antihypertensive medication, and 56 patients (80%) had intermittently high blood pressure. After surgery, the mean number of antihypertensive medication classes per patient was significantly reduced from 1.61 ± 0.77 pre-procedure to 1.27 ± 0.88 post-procedure (P < 0.001). The blood pressure of 48 of the 56 cases (86%) with preoperative intermittent high blood pressure returned to normal post procedure. A total of 50 patients (71%) recorded improvements on the hypertension control scale, with the overall mean score decreasing from 3.1 ± 1.0 preprocedure to 1.4 ± 1.0 post-procedure (P < 0.001). Therefore, successful laparoscopic fundoplication may result in better blood pressure control in some hypertensive GERD patients. This result suggests a possible connection between gastroesophageal reflux and hypertension.

Gastro-Esophageal Reflux Disease (GERD) defined as a condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications. Many drugs are used for the treatment of GERD such as omeprazole (a proton pump inhibitor) which is a widely used antiulcer drug demonstrated to protect against esophageal mucosal injury. Melatonin has been found to protect the gastrointestinal mucosa from oxidative damage caused by reactive oxygen species in different experimental ulcer models. The aim of this study is to evaluate the role of exogenous melatonin in the treatment of reflux disease in humans either alone or in combination with omeprazole therapy. 36 persons were divided into 4 groups (control subjects, patients with reflux disease treated with melatonin alone, omeprazole alone and a combination of melatonin and omeprazole for 4 and 8 weeks) Each group consisted of 9 persons. Persons were subjected to thorough history taking, clinical examination, and investigations including laboratory, endoscopic, record of esophageal motility, pH-metry, basal acid output and serum gastrin. Melatonin has a role in the improvement of Gastro-esophageal reflux disease when used alone or in combination with omeprazole. Meanwhile, omeprazole alone is better used in the treatment of GERD than melatonin alone. The present study showed that oral melatonin is a promising therapeutic agent for the treatment of GERD. It is an effective line of treatment in relieving epigastric pain and heartburn. However, further studies are required to confirm the efficacy and long-term safety of melatonin before being recommended for routine clinical use. QA13NCT00915616.

Endoscopic full-thickness plication allows transmural suturing at the gastroesophageal junction to recreate the antireflux barrier. Multichannel intraluminal impedance monitoring (MII) can be used to detect nonacid or weakly acidic reflux, acidic swallows, and esophageal clearance time. This study used MII to evaluate the outcome of endoscopic full-thickness plication. In this study, 12 subsequent patients requiring maintenance proton pump inhibitor therapy underwent endoscopic full-thickness plication for treatment of gastroesophageal reflux disease. With patients off medication, MII was performed before and 6-months after endoscopic full-thickness plication. The total median number of reflux episodes was significantly reduced from 105 to 64 (p = 0.016). The median number of acid reflux episodes decreased from 73 to 43 (p = 0.016). Nonacid reflux episodes decreased from 23 to 21 (p = 0.306). The median bolus clearance time was 12 s before treatment and 11 s at 6 months (p = 0.798). The median acid exposure time was reduced from 6.8% to 3.4% (p = 0.008), and the DeMeester scores were reduced from 19 to 12 (p = 0.008). Endoscopic full-thickness plication significantly reduced total reflux episodes, acid reflux episodes, and total reflux exposure time. The DeMeester scores and total acid exposure time for the distal esophagus were significantly improved. No significant changes in nonacid reflux episodes and median bolus clearance time were encountered.

Patients with gastroesophageal reflux disease (GERD) have decreased health-related quality of life (HRQL). The quality of life in patients with laryngopharyngeal reflux (LPR) symptoms is also significantly impaired. However, the impact of LPR symptoms on HRQL in GERD patients has not been studied. A nationwide, random-sample, and face-to-face survey of 300 Korean patients with GERD was conducted from January to March 2013. Gastroesophageal reflux symptoms were assessed using the Rome III questionnaire, LPR symptoms using the reflux symptom index, and HRQL using the EuroQol five dimensions (EQ-5D) questionnaire. A structured questionnaire on patient satisfaction, sickness-related absences, and health-related work productivity was also used. Among the 300 patients with GERD, 150 had LPR symptoms. The mean EQ-5D index was lower in patients with GERD and LPR symptoms than in those without LPR (0.88 vs 0.91, P = 0.002). A linear regression model showed that the severity of LPR symptoms was related to decreased HRQL and was independent of age, marital status, body mass index, or household income. The overall satisfaction rate regarding treatment was lower in patients with GERD and LPR (40.0% vs 69.1%, P = 0.040). GERD patients with LPR symptoms reported greater sickness-related absent hours per week (0.36 vs 0.02 h, P = 0.016) and greater percentages of overall work impairment than those without LPR (31.1% vs 20.8%, P < 0.001). Gastroesophageal reflux disease patients with LPR symptoms have a poorer HRQL, a lower satisfaction rate, and a greater disease burden than those without LPR. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Barrett's esophagus (BE) is the only known precursor of adenocarcinoma occuring in the lower third of the esophagus. According to statistics, severity and elapsed time of gastroesophageal reflux disease (GERD) are major pathogenetic factors in the development of Barrett's esophagus. In a retrospective study between 2001 and 2008, we compared the preoperative results (signs and sympthoms, 24 hour pH manometry, esophageal manometry, Bilitec) and treatment efficacy of 176 GERD patients and 78 BE patients, who have undergone laparoscopic Nissen procedure for reflux disease. The two groups of patients had similar demographic features, and elapsed time of reflux sympthoms were also equal. Both groups were admitted for surgery after a median time of 1.5 years (19.87 vs. 19.20 months) of ineffective medical (proton pump inhibitors) treatment. Preoperative functional tests showed a more severe presence of acid reflux in the BE group (DeMeester score 18.9 versus 41.9, p < 0.001). On the other hand, mano-metry - despite confirming lower esophageal sphincter (LES) damage - did not show difference between the two groups (12.10 vs. 12.57 mmHg, p = 0.892). We did not experience any mortality cases with laparoscopic antireflux procedures, although in two cases we had to convert during the operation (1 due to extensive adhesions, and 1 due to injury to the spleen). 3 months after the procedure - according to Visick score - both groups experienced a significant decrease, or lapse in reflux complaints (group I: 73%, group II: 81% of patients), LES functions improved (17.58 vs.18.70 mmHg), and the frequency and exposition of acid reflux decreased (DeMeester score 7.73 vs. 12.72). The severity of abnormal acid reflux occuring parallel with the incompetent function of the damaged LES triggers not only inflammation in the gastroesophageal junction (GEJ), but also metaplastic process, and the development of Barrett's esophagus.

High-resolution manometry (HRM) allows nuanced evaluation of esophageal motor function, and more accurate evaluation of lower esophageal sphincter (LES) function, in comparison with conventional manometry. Pathophysiologic correlates of gastroesophageal reflux disease (GERD) and esophageal peristaltic performance are well addressed by this technique. HRM may alter the surgical decision by assessment of esophageal peristaltic function and exclusion of esophageal outflow obstruction before antireflux surgery. Provocative testing during HRM may assess esophageal smooth muscle peristaltic reserve and help predict the likelihood of transit symptoms following antireflux surgery. HRM represents a continuously evolving new technology that compliments the evaluation and management of GERD. Copyright © 2014 Elsevier Inc. All rights reserved.

To study the relationship between esophageal motor functional disorder [decreased lower esophageal sphincter pressure (LESP)and ineffective motility (IEM)] and gastroesophageal reflux disease (GERD). Totally 89 patients with GERD were enrolled in this study. All of them underwent 24-hour pH monitoring with dual-channel probe and stationary esophageal manometry. In addition, 77 of these patients underwent upper endoscopy. IEM and LES, 10 mmHg were common disturbances in patients with GERD (54% and 48%, respectively). The number of the acid reflux events of distal esophagus and prevalence of moderate or severe erosive esophagitis (EE) were significantly higher in patients with low LESP and IEM than patients without low LESP ( P<0.05). The number of the acid reflux events in distal esophagus was significantly correlated with the severity of esophagitis, distal esophagus amplitude, and LESP, while no such correlation was found between IEM and degree of esophageal acid exposure or esophagitis. The pathophysiology of GERD is probably multifactorial. Lower LESP or IEM is not a independent pathophysiological factor for GERD. However,one single factor is insufficient to explain all the pathogenic mechanism of GERD.

This research aimed to evaluate the effect of metoclopramide and ranitidine in the prevention of gastroesophageal reflux episodes during anesthetic procedures. Ninety healthy female dogs were submitted to elective ovariosalpingohisterectomy, randomly divided into three groups of 30 animals. The control group received only the anesthetic protocol. The metoclopramide group received an intravenous bolus of 1mg/kg, and continuous infusion (1 mg/kg/h intravenously) immediately after anesthetic induction. The ranitidine group received an intravenous bolus of 2 mg/kg, 6 h before anesthesia. Anesthesia (acepromazine, propofol and isofluorane) was standardized and the esophageal pH variations were recorded. Esophagoscopy was carried out after surgery. No difference (p<0.05) was verified in the reflux episodes between the groups. Seven animals presented reflux. Metoclopramide in bolus and continuous infusion, as well as ranitidine, 6 h before anesthesia, did not influence the reduction of the incidence of gastroesophageal reflux.

Available data about reflux patterns and symptom determinants in the gastroesophageal reflux disease (GERD) subtypes off proton pump inhibitor (PPI) therapy are lacking. We aimed to evaluate reflux patterns and determinants of symptom perception in patients with GERD off PPI therapy by impedance-pH monitoring. We retrospectively reviewed the impedance-pH data in patients diagnosed as GERD based on results of impedance-pH monitoring, endoscopy and/or typical symptoms. The characteristics of acid and weakly acidic reflux were evaluated. Symptomatic and asymptomatic reflux were compared according to GERD subtypes and individual symptoms. Forty-two patients (22 males, mean age 46 years) were diagnosed as GERD (17 erosive reflux disease, 9 pH(+) non-erosive reflux disease [NERD], 9 hypersensitive esophagus and 7 symptomatic NERD). A total of 1,725 reflux episodes were detected (855 acid [50%], 857 weakly acidic [50%] and 13 weakly alkaline reflux [< 1%]). Acid reflux was more frequently symptomatic and bolus clearance was longer compared with weakly acidic reflux. In terms of globus, weakly acidic reflux was more symptomatic. Symptomatic reflux was more frequently acid and mixed reflux; these associations were more pronounced in erosive reflux disease and symptomatic NERD. The perception of regurgitation was related to acid reflux, while that of globus was more related to weakly acidic reflux. In patients not taking PPI, acid reflux was more frequently symptomatic and had longer bolus clearance. Symptomatic reflux was more frequently acid and mixed type; however, weakly acidic reflux was associated more with globus. These data suggest a role for impedance-pH data in the evaluation of globus.

To investigate the clinical and pathogenetic features of the non-acidic types of gastroesophageal reflux disease (GERD) and to evaluate the impact of combined therapy versus monotherapy on the course of this disease. The investigation enrolled 62 patients with non-acidic GERD. The follow-up period was 6 weeks. The patients were divided into 2 groups: 1) weakly acidic gastroesophageal refluxes (GER); 2) weakly alkaline GER. Then each group was distributed, thus making up 4 groups: 1) 19 patients with weakly acidic GER who received monotherapy with rabeprazole 20 mg/day; 2) 21 patients with weakly acidic GER had combined therapy with rabeprazole 20 mg and itopride; 3) 8 patients with weakly alkaline GER who received ursodeoxycholic acid (UDCA) monotherapy; and 4) 14 patients with weakly alkaline GER who had combined therapy with UDCA and itopride, The clinical symptoms of the disease, the endoscopic pattern of the upper gastrointestinal tract (GIT) mucosa, histological changes in the esophageal and gastric mucosa, and the results of 24-hour impedance pH monitoring were assessed over time. During differentiation therapy, the majority of patients reported positive clinical changes and an improved or unchanged endoscopic pattern. Assessment of impedance pH monitoring results revealed decreases in the overall number of GERs, the presence of a bolus in the esophagus, and the number of proximal refluxes. These changes were noted not only in patients taking proton pump inhibitors (PPIs), but also in those treated with UDCA monotherapy or combined PPI and prokinetic therapy. A differentiated approach to non-acidic GER treatment contributes to its efficiency. Adding the prokinetic itomed (itopride hydrochloride) to PPI therapy in a patient with weakly acidic GER enhances the efficiency of treatment, by positively affecting upper GIT motility. The mainstay of therapy for GERD with a predominance of weakly alkaline refluxes is UDCA, the combination of the latter and the

Background Obesity is a risk factor for asthma. Obese asthmatics often have poor asthma control and respond poorly to therapy. It has been suggested that co-morbidities associated with obesity, such as reflux and obstructive sleep apnea, could be important factors contributing to poor asthma control in obese patients. Objectives The purpose of this study was to determine if (i) reflux and/or (ii) symptoms of sleep apnea contribute to poor asthma control in obesity. Methods We studied asthmatic subjects participating in a trial of reflux treatment. Participants underwent baseline evaluation of asthma symptoms and lung function. 304 participants underwent esophageal pH probe testing. 246 participants were evaluated for obstructive sleep apnea symptoms. Results Of 402 participants in this trial, 51% were obese. Role of reflux in asthma control Those with higher body mass index reported a higher prevalence of reflux symptoms, but the prevalence of pH probe acid reflux was similar in all groups. Reflux was not associated with measures of asthma control in obese patients. Role of obstructive sleep apnea in asthma control Symptoms and self-report of obstructive sleep apnea were more common with increasing body mass index and associated with worse asthma control as measured by the Juniper Asthma Control Questionnaire and Asthma Symptom Utility Index. Conclusions Our data suggest that obstructive sleep apnea, but not gastroesophageal reflux disease may contribute significantly to poor asthma control in obese patients. PMID:21819338

Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal pathology in infants and young children. Ultrasonography (US) has been considered to be a reliable diagnostic tool for GERD but the severity of GERD and the clinical implications based on imaging findings has not been evaluated. To compare the diagnostic value of lower esophageal US with that of barium swallow in demonstrating the severity of GERD. Fifty one pediatric patients, age between 1 month to 12 years, 34 male and 17 female with clinical suspicion of GERD were included. The patients were initially submitted to barium swallow (BS) and subsequently to transabdominal US. During BS, the number of gastroesophageal reflux episodes was documented in a 5-minute period. Transabdominal US documented the number and duration of reflux episodes during a 5-minute period, the angle of His, mucosal thickness, and intraabdominal esophageal length (IAEL). Duration and number of reflux episodes in US were significantly higher in patients that had severe gastroesophageal refluxes at BS. At US the cutoff point of 9.5 seconds (sensitivity 80%, specificity 60%) for reflux duration and more than 2 episodes in 5 minute ultrasound study (sensitivity 75%, specificity 58%) were defined to correlate with severe gastroesophageal reflux at BS.The angle of His, the esophageal wall mucosal thickness, and the IAEL did not correlate with the severity of GERD detected in BS. US can predict the severity of GERD. Therefore, except in the case of specific patients in whom mechanical causes are suspected to be responsible for GERD, BS can be replaced by US.

Medical therapy remains the most popular treatment for gastroesophageal reflux disease (GERD). Whilst interest in drug development for GERD has declined over the last few years primarily due to the conversion of most proton pump inhibitor (PPI)'s to generic and over the counter compounds, there are still numerous areas of unmet needs in GERD. Drug development has been focused on potent histamine type 2 receptor antagonist's, extended release PPI's, PPI combination, potassium-competitive acid blockers, transient lower esophageal sphincter relaxation reducers, prokinetics, mucosal protectants and esophageal pain modulators. It is likely that the aforementioned compounds will be niched for specific areas of unmet need in GERD, rather than compete with the presently available anti-reflux therapies. PMID:24466441

The prokinetic agent cisapride is effective for the treatment of gastroesophageal reflux disease (GERD) in infants and children, but is no longer used for this purpose because of safety concerns. Therefore, other pharmacological agents need to be investigated for efficacy in GERD treatment. In this study, we examined the effectiveness and safety of mosapride for the treatment of neurologically impaired children and adolescents with GERD. Mosapride (0.3 mg/kg/day) was administered to 11 neurologically impaired patients with GERD (five male; median age, 12.3 years). Esophageal acid exposure was measured using esophageal pH monitoring before and at >5 days after the start of mosapride treatment. The pressure and length of the lower esophageal sphincter were compared before and after mosapride treatment. In the 11 patients, median reflux index (percentage of the total monitoring period during which recorded pH was <4.0) was 17.5% (range, 4.4-59%) before and 8.2% (range, 2.8-20.7%) after mosapride treatment (P = 0.02). Median esophageal clearance was 1.0 min/reflux (range, 0.5-2.1 min/reflux) before and 0.7 min/reflux (range, 0.4-1.2 min/reflux) after treatment with mosapride (P = 0.02). The median number of reflux episodes before (219) and after (122) drug treatment did not differ significantly. The decreased reflux index in neurologically impaired patients with GERD is due to mosapride, therefore mosapride may be a candidate for GERD treatment. © 2016 Japan Pediatric Society.

Background/Aims Gastroesophageal reflux disease (GERD) is one of the main causes of chronic cough. We evaluated the role of microaspiration in the pathogenesis of reflux-related cough by determining the amount of lipid-laden macrophages (LLMs) in bronchoalveolar lavage (BAL) specimens. Methods A total of 161 cases of chronic cough were evaluated, and 36 patients (average age 48.2 years) were recruited for this single center prospective study. Patients with a history of smoking, angiotensin converting enzyme inhibitor usage, any abnormality on pulmonary function tests, abnormal chest X-rays, occupational or environmental exposures, or upper airway cough syndrome were excluded. GERD was evaluated by 24-hour esophageal impedance-pH monitoring. BAL specimens for LLM determination were obtained from 34 patients by flexible bronchoscopy. Results Patients with pathological intra-esophageal reflux according to multichannel intraluminal impedance and pH monitoring had higher LLM positivity in BAL specimens than patients without pathological reflux (8/14 in reflux positive group vs 1/22 in reflux negative group; P = 0.004). The BAL cell distribution was not different between the 2 groups (P = 0.574 for macrophages, P = 0.348 for lymphocytes, P = 0.873 for neutrophils and P = 0.450 for eosinophils). Conclusions Our results confirm the role of the microaspiration of refluxate in the pathogenetic mechanism of chronic cough. While bronchoscopy is indicated in patients with chronic cough, in addition to the routine airway evaluation, BAL and LLM detection should be performed. LLM can be used to diagnose aspiration in reflux-related chronic cough. Future studies are needed to evaluate the response to anti-reflux medications or surgery in patients with LLM positivity.

Comprehensive guidelines for the diagnosis and management of gastro-esophageal reflux (GER) and GER disease (GERD) were developed by the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition. GERD is reflux associated with troublesome symptoms or complications. The recognition of GER and GERD is relevant to implement best management practices. A conservative management is indicated in infants with uncomplicated physiologic reflux. Children with GERD may benefit from further evaluation and treatment. Since the publications of the European and North American Societies for Pediatric Gastroenterology, Hepatology and Nutrition guidelines in 2009, no important novelties in drug treatment have been reported. Innovations are mainly restricted to the management of regurgitation in infants. During the last 5 years, pros and cons of multichannel intraluminal impedance have been highlighted. However, overall 'not much has changed' in the diagnosis and management of GER and GERD in infants and children.

Gastro-esophageal reflux time parameters and esophagitis in children

The aim of this work was to study the correlation between the reflux timing and the presence of esophagitis, an inconstant but serious complication of gastro-esophageal reflux (GER). The hypothesis was that reflux occurring late after meal can be incriminated more than early reflux in esophagitis genesis. 32 children with GER (mean age = 10.5 months, 2 to 30 months) had esophagoscopy and scintigraphy in the same week. The children were classified in two groups according to esophagoscopy: group 1 (n = 18) no esophagitis, group 2 (n = 14) esophaqgitis. The scintigraphy involved the ingestion of 0.5 mCi Tc-99mmore » sulfur colloid milk mixture, followed by esophageal and gastric activity recording (one image per minute for 1 hour). The reflux was assessed from contrast enhanced images and esophageal time activity curves. Reflux intensity was quantitated by reflux index (Re). Mean reflux time was calculated as the mean esophageal activity peaks time (t-bar). Finally a composite parameter was calculated as the mean reflux time weighted by the relative intensity of each reflux peak (t-barw). Re was not found to be different between the two groups. t-bar was significantly higher in group 2: t-bar = 29.6 +- 3.0 mn (mean +- SD) than in group 1: t-bar = 24.5 +- 6.8 mn; rho <0.02. The difference between the two groups was enhanced by intensity weighting: group 1: t-barw = 16.6 +- 6.3 mn, group 2: t-barw = 33.5 +- 7.1 mn rho <0.001. t-barw value was not correlated to esophagitis grade. These results suggest that late reflux is more likely responsible of esophagitis.« less

Lung transplantation is one of the highest risk solid organ transplant modalities. Recent studies have demonstrated a relationship between gastroesophageal reflux disease (GERD) and lung transplant outcomes, including acute and chronic rejection. The aim of this review is to discuss the pathophysiology, evaluation, and management of GERD in lung transplantation, as informed by the most recent publications in the field. The pathophysiology of reflux-induced lung injury includes the effects of aspiration and local immunomodulation in the development of pulmonary decline and histologic rejection, as reflective of allograft injury. Modalities of reflux and esophageal assessment, including ambulatory pH testing, impedance, and esophageal manometry, are discussed, as well as timing of these evaluations relative to transplantation. Finally, antireflux treatments are reviewed, including medical acid suppression and surgical fundoplication, as well as the safety, efficacy, and timing of such treatments relative to transplantation. Our review of the data supports an association between GERD and allograft injury, encouraging a strategy of early diagnosis and aggressive reflux management in lung transplant recipients to improve transplant outcomes. Further studies are needed to explore additional objective measures of reflux and aspiration, better compare medical and surgical antireflux treatment options, extend follow-up times to capture longer-term clinical outcomes, and investigate newer interventions including minimally invasive surgery and advanced endoscopic techniques.

The purpose of this study was to investigate the impact of gastroesophageal reflux disease (GERD) on dental erosion (DE) in children and analyze the association between dental erosion and diet, oral hygiene, and sociodemographic characteristics. This case-control study encompassed 43 two- to 14-year-olds diagnosed positive for GERD by the 24-hour pH monitoring, paired by age group with 136 healthy controls, in Belo Horizonte, Minas Gerais, Brazil. DE was assessed by one calibrated examiner using the O'Sullivan index. A questionnaire was self-administered by parents collecting information regarding sociodemographics, oral hygiene, and dietary habits. Dental erosion experience was compared between the groups, and a stratified analysis was performed (P<0.05). Dental erosion was diagnosed in 10.6 percent (N equals 19) of all the children; 25.6 percent (N equals 11) of GERD children and 5.9 percent (N equals eight) of children without GERD, P=0.001). Dental erosion was not associated with dietary consumption or sociodemographic characteristics in both groups (P≥0.05). Children who used adult toothpaste had a 5.79 higher chance of having dental erosion in the group with GERD. Children diagnosed with gastroesophageal reflux disease were at an increased risk of having dental erosion when compared to healthy subjects; among the GERD children, dental erosion was associated with the use of adult toothpaste.

Little data is available on the risk of gastroesophageal reflux disease in patients diagnosed with Sjögren's syndrome. We identified 4650 Sjögren's syndrome patients between 2000 and 2011 from the National Health Insurance Research Database. Each Sjögren's syndrome patient was matched to 4 controls based on age, sex, and index year, and all subjects were followed up from the index date to December 31, 2011. Cox proportional hazards regression model was used to estimate the risk of gastroesophageal reflux disease. The risk of gastroesophageal reflux disease for Sjögren's syndrome patients was 2.41-fold greater than that for the comparison cohort after adjusting for age, sex, and comorbidities. In age stratified analyses, the youngest Sjögren's syndrome cohort (age: 20-44years old) had the highest risk (HR=3.02; 95% CI=2.48-3.69) and the lowest risk at age ≥65years (HR=1.95; 95% CI=1.61-2.36). Regardless of in subjects with and without comorbidity, Sjögren's syndrome patients had a higher risk than the controls. Sjögren's syndrome subjects with ischemic heart disease, hyperlipidemia and renal disease had the highest risk for gastroesophageal reflux disease compared with the comparison cohort without those diseases (HR=7.67; 95% CI=5.32-11.1). Patients with Sjögren's syndrome have a significantly greater risk of developing subsequent gastroesophageal reflux disease than the general population.

A significant percentage of patients with gastroesophageal reflux disease (GERD) will not respond to proton pump inhibitor (PPI) therapy. The causes of PPI-refractory GERD are numerous and diverse, and include adherence, persistent acid, functional disorders, nonacid reflux, and PPI bioavailability. The evaluation should start with a symptom assessment and may progress to imaging, endoscopy, and monitoring of esophageal pH, impedance, and bilirubin. There are a variety of pharmacologic and procedural interventions that should be selected based on the underlying mechanism of PPI failure. Pharmacologic treatments can include antacids, prokinetics, alginates, bile acid binders, reflux inhibitors, and antidepressants. Procedural options include laparoscopic fundoplication and LINX as well as endoscopic procedures, such as transoral incisionless fundoplication and Stretta. Several alternative and complementary treatments of possible benefit also exist. PMID:29606884

Gastroesophageal reflux disease (GERD) is highly prevalent in the Western world. Patients with GERD have a 10-fold increased risk to develop a Barrett's esophagus. Patients with Barrett's esophagus have a higher risk for an esophageal adenocarcinoma. Men have more severe reflux with a higher grade of inflammation and acid reflux. This seems to be the reason why men develop a Barrett's esophagus more frequently - the risk is approximately 2-3-fold and the risk for an esophageal adenocarcinoma is even 3-6 times higher. © Georg Thieme Verlag KG Stuttgart · New York.

The National Ambulatory Medical Care Survey (NAMCS) database was utilized to understand evolving national trends in diagnosis and management of reflux. The NAMCS database was queried for visits related to gastroesophageal reflux diagnosis and management. Analysis performed for time periods 1998-2001, 2002-2005, and 2006-2009 was weighted to provide national estimates of care. Results were compared to previously reported time periods from 1990 to 2001 to evaluate patterns in overall visits, age and ethnicity of patients, provider type, and prescriptions provided. The number of ambulatory visits for reflux increased from 8 684 000 in 1998-2001 to 15 750 000 in 2006-2009. Visits increased across each time period for internal medicine, family, and gastroenterology physicians. Among otolaryngologists, absolute visits increased from 1998-2001 to 2002-2005 but decreased in 2006-2009; difference between these time periods did not reach statistical significance. From 1998-2001 to 2006-2009, reflux medication use increased 233%, with continuing trends toward increased proton pump inhibitor use. Reflux visits have increased across all demographic subgroups studied. Knowledge of these trends may inform further paradigm shifts in diagnosis and management of reflux.

This paper was designed to discuss the problems of co-morbidity and approaches to the rehabilitation of the patients presenting with gastroesophageal reflux disease and a concomitant pathology and to analyze the issues concerning the possible vertebro-visceral correlations inherent in the diseases of the internal organs. To evaluate the vertebro-neurological status of the thoracic segment of the vertebral column in the patients suffering from gastroesophageal reflux disease and to further improve the methods for their treatment taking into consideration the concomitant pathology, if any. A total of 290 patients at the age varying from 25 to 60 (mean 44,3±11,3) years with the non-erosive form of gastroesophageal reflux disease were examined in the phase of its exacerbation. They included 132 (45.5%) men and 158 (54.5%) women. The duration of the disease averaged 13.1±3.3 years and that of the exacerbation period 1.2±0.5 months. All the patients underwent the vertebro-neurological examination. The visual analog scale was used to obtain the subjective characteristics of the pain syndrome associated with thoracalgia The quality of life of the patients was estimated based on the Medical Outcomes Study Short Form-36 (scores of MOS SF-36). To evaluate the effectiveness of the proposed approach to the treatment of the gastroesophageal reflux disease, the 260 participants of the study were randomly allocated to two groups, the main and control ones. The latter group was comprised of 130 patients given the standard treatment including the use of histamine H2-receptor antagonists, proton pump inhibitors, stimulators of the motility of the gastrointestinal tract, alginates, and other drugs, as indicated. The former group consisted of the remaining 130 patients undergoing the standard course of pharmacopuncture to correct the functional disorders in the thoracic segment of the vertebral column. The medications of choice for the purpose were the anti-homotoxic agents, such as

There have been no studies investigating the distribution of abnormal gastroesophageal flap valve (GEFV) among patients with dyspepsia, non-erosive reflux disease (NERD), and reflux esophagitis (RE) in the same set of patients. The aims of this study are to investigate (1) the association between GEFV and gastroesophageal reflux disease questionnaire (GERDQ) score, and (2) the distribution of abnormal GEFV in Vietnamese patients presenting with upper gastrointestinal symptoms. Three hundred and thirty-one patients recruited in this prospective cross-sectional study were classified into 3 groups: reflux esophagitis (RE), non-erosive reflux disease (NERD) (GERDQ score ≥ 8, no endoscopic mucosal injury), and dyspepsia (GERDQ score < 8, no endoscopic mucosal injury). The GEFV was graded endoscopically according to the Hill classification. GEFV grades I and II were regarded as normal, while grades III and IV were regarded as abnormal GEFV. There were 215 (65.0%) patients with dyspepsia, 55 (16.6%) patients with NERD, and 61 (18.4%) patients with RE. Abnormal GEFV was an independent risk factor for GERD (OR, 2.93; CI 95%, 1.76-4.88) and RE (OR, 3.41; CI 95%, 1.78-6.53). The mean GERDQ score of patients with abnormal GEFV was significantly higher than that of patients with normal GEFV (5.7 ± 2.4 vs 4.9 ± 2.7, P = 0.011). The prevalence of abnormal GEFV gradually increased in patients with dyspepsia (27.4%), NERD (43.6%), grade A RE (56.8%), and grades B/C RE (80.0%) ( P ＜ 0.001). Abnormal GEFV was significantly associated with high GERDQ score. Its prevalence gradually increased in patients with dyspepsia, NERD, and RE, respectively.

Congenital diaphragmatic hernia survivors are a well-known group at risk for developing gastroesophageal reflux disease that may be particularly long-term severe. The aim of this study is to provide a systematic review of the prevalence of gastroesophageal reflux in infant and children survivors treated for congenital diaphragmatic hernia.Electronic and manual searches were performed with keywords related to congenital diaphragmatic hernia, gastroesophageal reflux disease, and epidemiology terms. Summary estimates of the prevalence were calculated. Effect model was chosen depending on heterogeneity (I2). Factors potentially related with the prevalence, including study quality or the diagnostic strategy followed, were assessed by subgroup and meta-regression analyses. Risk of publication bias was studied by funnel plot analysis and the Egger test.The search yielded 140 articles, 26 of which were included in the analyses and provided 34 estimates of prevalence: 21 in patients aged 12 months or younger, and 13 in older children. The overall prevalence of gastroesophageal reflux disease in infants was 52.7% (95% confidence interval [CI]: 43.2% to 62.1%, I2 = 88.7%) and, in children over 1 year old, 35.1% (95% CI: 25.4% to 45.3%, I2 = 73.5%). Significant clinical and statistical heterogeneity was found. The strategy chosen for gastroesophageal reflux diagnosis influenced the reported prevalence. The only estimate obtained with a systematic use of multichannel intraluminal impedance provided a higher prevalence in both age groups: 83.3% (95% CI: 67.2% to 93.6%) and 61.1% (95% CI: 43.5% to 76.9%) respectively. This last prevalence did not significantly differ from that obtained using only low risk of bias estimates.As a conclusion, gastroesophageal reflux disease is commonly observed after congenital diaphragmatic hernia repair and is almost constantly present in the first months of life. It may be underdiagnosed if systematically esophageal monitoring is not

Sex and Gender Differences in Gastroesophageal Reflux Disease

It is important to understand sex and gender-related differences in gastroesophageal reflux disease (GERD) because gender-related biologic factors might lead to better prevention and therapy. Non-erosive reflux disease (NERD) affects more women than men. GERD symptoms are more frequent in patients with NERD than in those with reflux esophagitis. However, men suffer pathologic diseases such as reflux esophagitis, Barrett’s esophagus (BE), and esophageal adenocarcinoma (EAC) more frequently than women. The prevalence of reflux esophagitis is significantly increased with age in women, especially after their 50s. The mean age of EAC incidence in women is higher than in men, suggesting a role of estrogen in delaying the onset of BE and EAC. In a chronic rat reflux esophagitis model, nitric oxide was found to be an aggravating factor of esophageal injury in a male-predominant way. In addition, the expression of esophageal occludin, a tight junction protein that plays an important role in the esophageal defense mechanism, was up-regulated in women. This explains the male predominance of reflux esophagitis and delayed incidence of BE or EAC in women. Moreover, the symptoms such as heartburn, regurgitation, and extra-esophageal symptoms have been more frequently reported by women than by men, suggesting that sex and gender play a role in symptom perception. Differential sensitivity with augmented symptoms in women might have diagnostic and therapeutic influence. Furthermore, recent studies have suggested that hormone replacement therapy has a protective effect against esophageal cancer. However, an anti-inflammatory role of estrogen remains compelling, which means further study is necessary in this area. PMID:27703114

Gastroesophageal reflux disease is thought to predispose to adverse lung allograft outcomes. However, little is known about the burden of gastroesophageal reflux (GER) and gastroparesis in pediatric patients. In this study we describe the burden of reflux and gastroparesis in children undergoing lung transplant, and evaluates their impact on allograft survival and rejection incidence. This study is a retrospective analysis of pediatric lung transplant recipients who had combined pH and multichannel intraluminal impedance testing (pH-MII) and gastric-emptying scans (GES). Hazard ratios with 95% confidence intervals (CIs) estimated from Cox proportional hazard models were used to examine the associations between reflux parameters and adverse allograft outcomes. Covariates considered in the multivariate analysis included abnormal pH-MII testing, abnormal GES and Nissen fundoplication status. Kaplan-Meier curves were created, with log-rank testing employed to assess differences between groups. Thirty lung transplant recipients, aged 1 to 21 years, were identified. Eight of 30 patients (27%) had abnormal reflux by impedance, and 12 (40%) had abnormal pH-metry. Of 19 patients tested, 5 (26.3%) had evidence of gastric dysmotility; however, the severity of GER did not trend with delays in gastric emptying. Neither reflux burden by pH-MII testing nor fundoplication status impacted survival or rejection. However, delayed gastric emptying appeared significantly linked to the development of chronic lung allograft dysfunction, independent of GER. In children, reflux burden and fundoplication status do not impact lung transplant outcomes, but gastric dysmotility may be linked to allograft dysfunction in children.

Background: The association of gastro-esophageal reflux (GER) with a wide variety of pulmonary disorders was recognized. We aimed to evaluate the effect of GER-induced esophagitis on airway hyper-reactivity (AHR) in patients and the response to treatment. Materials and Methods: In this cohort study, 30 patients attending the gastrointestinal clinic of a university hospital with acid reflux symptoms were included. All patients were evaluated endoscopically and divided into case group with esophagitis and control group without any evidence of esophagitis. Spirometry and methacholine test were done in all patients before and after treatment of GER with pantoprazole 40 mg daily for six months. Results: There was a significant difference in the rate of positive methacholine test between the cases (40%) and the controls (6.7%) prior to anti-acid therapy (P < 0.0001). After six months of treatment, the frequency of positive methacholine test diminished from 40 to 13.3% in the case group (P < 0.05) but did not change in the controls (P = 0.15). Conclusion: The presence of esophagitis due to GER would increase the AHR and treatment with pantoperazole would decrease AHR in patients with proved esophagitis and no previous history of asthma after six months.

Background/Aims The incidence of gastroesophageal reflux disease (GERD) is increasing in Korea. The aim of this study was to evaluate the relationship between GERD symptoms and dietary factors in Korea. Methods From January 2007 to April 2008, 162 subjects were enrolled (81 in GERD group and 81 in control group). They were asked to complete the questionnaires about GERD symptoms and dietary habits. The symptom severity score was recorded by visual analogue scale. Results Subjects with overweight or obesity had an increased risk for GERD (OR, 2.52; 95% CI, 1.18-5.39). Irregular dietary intake was one of the risk factors for GERD (OR, 2.33; 95% CI, 1.11-4.89). Acid regurgitation was the most suffering (2.85 ± 2.95 by visual analogue scale) and frequent reflux-related symptom (57.5%) in GERD. Noodles (OR, 1.22; 95% CI, 1.12-1.34), spicy foods (OR, 1.09; 95% CI, 1.02-1.16), fatty meals (OR, 1.20; 95% CI, 1.09-1.33), sweets (OR, 1.42; 95% CI, 1.00-2.02), alcohol (OR, 1.16; 95% CI, 1.03-1.31), breads (OR, 1.17; 95% CI, 1.01-1.34), carbonated drinks (OR, 1.69; 95% CI, 1.04-2.74) and caffeinated drinks (OR,1.41; 95% CI, 1.15-1.73) were associated with symptom aggravation in GERD. Among the investigated noodles, ramen (instant noodle) caused reflux-related symptoms most frequently (52.4%). Conclusions We found that noodles, spicy foods, fatty meals, sweets, alcohol, breads, carbonated drinks and caffeinated drinks were associated with reflux-related symptoms. PMID:21369492

The effects of sleeve gastectomy on gastro-esophageal reflux and gastro-esophageal motility.

PubMed

Hayat, Jamal O; Wan, Andrew

2014-05-01

Sleeve gastrectomy is an increasingly performed bariatric procedure associated with low morbidity and good short to medium term effects on weight loss and comorbid conditions. Studies assessing the prevalence of post-operative gastro-esophageal reflux disease (GERD), show sleeve gastrectomy may provoke de novo GERD symptoms or worsening of pre-existing GERD. Pathophysiological mechanisms of GERD after sleeve gastrectomy include a hypotensive lower esophageal sphincter, increased gastro-esophageal pressure gradient and intra-thoracic migration of the remnant stomach. A reduction in the compliance of the gastric remnant may provoke an increase in transient lower esophageal sphincter relaxations. Time-resolved MRI suggests relative gastric stasis in the proximal remnant and increased emptying from the antrum. A lack of standardisation of technique, along with heterogeneity of studies assessing GERD may explain the wide variability in reported results. Simultaneous and careful repair of an associated hiatus hernia may result in a reduction in the prevalence of post-operative GERD.

A high prevalence of gastroesophageal reflux (GERD) has been observed in individuals with cerebral palsy (CP). One of the main risks for dental erosion is GERD. This study aimed to evaluate the presence of GERD, variables related to dental erosion and associated with GERD (diet consumption, gastrointestinal symptoms, bruxism), and salivary flow rate, in a group of 46 non-institutionalized CP individuals aged from 3 to 13 years. Twenty CP individuals with gastroesophageal reflux (GERDG) and 26 without gastroesophageal reflux (CG) were examined according to dental erosion criteria, drinking habits, presence of bruxism, and salivary flow rate. A face-to-face detailed questionnaire with the consumption and frequency of acid drinks, gastrointestinal symptoms (regurgitation and heart burn), and the presence of bruxism were answered by the caregivers of both groups. Unstimulated whole saliva was collected under slight suction, and salivary flow rate (ml/min) was calculated. The GERDG presented higher percentages of younger quadriplegics individuals compared to CG. The presence of regurgitation, heart burn, and tooth erosion (Grade 1) was significantly more prevalent in GERDG. It was observed difference in the salivary flow rate between the studied groups. On logistic multivariate regression analysis, the unique variable independently associated with the presence of GERD was dental erosion (P = 0.012, OR 86.64). The presence of GERD contributes significantly to dental erosion in the most compromised individuals with quadriplegics cerebral palsy individuals, increasing the risk of oral disease in this population. © 2011 John Wiley & Sons A/S.

Gastroesophageal reflux disease (GERD) is diagnosed based on typical symptoms in clinical practice. It can be divided into two groups using endoscopy: erosive and nonerosive reflux disease (NERD). This study aims to determine the risk factors of reflux symptoms and mucosal injury. This was a two-step case-control study derived from a cohort of 998 individuals having the data of reflux disease questionnaire (RDQ) and endoscopic findings. Those with minor reflux symptoms were excluded. The first step compared symptomatic GERD patients with healthy controls. The 2(nd) step compared patients with erosive esophagitis with healthy controls. In this study, the prevalence of symptomatic GERD and erosive esophagitis were 163 (16.3%) and 166 (16.6%), respectively. A total of 507 asymptomatic individuals without mucosal injury of the esophagus on endoscopy were selected as healthy controls. Compared with healthy controls, multivariate analyses showed that symptomatic GERD patients had a higher prevalence of hypertriglyceridemia [odds ratio (OR), 1.83; 95% confidence interval (CI) 1.13-2.96] and obesity (OR, 1.85; 95% CI 1.08-3.02). By contrast, male sex (OR, 2.24; 95% CI 1.42-3.52), positive Campylo-like organism (CLO) test (OR, 0.56; 95% CI 0.37-0.84), and hiatus hernia (OR, 14.36; 95% CI 3.05-67.6) were associated with erosive esophagitis. In conclusion, obesity and hypertriglyceridemia were associated with reflux symptoms. By contrast, male sex, negative infection of Helicobacter pylori, and hiatus hernia were associated with mucosal injury. Our results suggested that risk factors of reflux symptoms or mucosal injury might be different in GERD patients. The underlying mechanism awaits further studies to clarify. Copyright © 2015.

Impact of obesity treatment on gastroesophageal reflux disease

2016-01-01

Gastroesophageal reflux disease (GERD) is a frequently encountered disorder. Obesity is an important risk factor for GERD, and there are several pathophysiologic mechanisms linking the two conditions. For obese patients with GERD, much of the treatment effort is focused on weight loss and its consistent benefit to symptoms, while there is a relative lack of evidence regarding outcomes after novel or even standard medical therapy is offered to this population. Physicians are hesitant to recommend operative anti-reflux therapy to obese patients due to the potentially higher risks and decreased efficacy, and these patients instead are often considered for bariatric surgery. Bariatric surgical approaches are broadening, and each technique has emerging evidence regarding its effect on both the risk and outcome of GERD. Furthermore, combined anti-reflux and bariatric options are now being offered to obese patients with GERD. However, currently Roux-en-Y gastric bypass remains the most effective surgical treatment option in this population, due to its consistent benefits in both weight loss and GERD itself. This article aims to review the impact of both conservative and aggressive approaches of obesity treatment on GERD. PMID:26819528

To investigate the association between esophageal motility and acid reflux in patients with gastroesophageal reflux disease (GERD). A total of 94 patients with typical reflux symptoms such as heartburn, regurgitation and chest pain, whose score (Sc) of reflux diagnostic questionnaire (RDQ) was greater than or equal to 12 were enrolled in the study. Each participant was evaluated by upper gastrointestinal endoscopy, high resolution manometry (HRM) of esophagus and 24 h esophageal pH monitoring. The participants were divided into groups of reflux esophagitis (RE) and non-erosive reflux disease (NERD) on the basis of endoscopy findings. The 24 h esophageal pH monitoring categorized participants into physiologic reflux (pH) and pathologic reflux (pH+). The characteristics of esophageal motility and acid reflux were compared between the two groups of participants. Lower but non-significant differences (P > 0.05) were found in pressure of lower esophageal sphincter (LESP), length of lower esophageal sphincter (LESL), esophageal contraction amplitude (CA), distal contractile integral (DCI) and effective peristalsis proportion (EPP) in the participants in the RE group compared with those in the NERD group.

Background. Gastroesophageal reflux disease is a common condition with increasing prevalence worldwide. The disease encompasses a broad spectrum of clinical symptoms and disorders from simple heartburn without esophagitis to erosive esophagitis with severe complications, such as esophageal strictures and intestinal metaplasia. Diagnosis is based mainly on ambulatory esophageal pH testing and endoscopy. There has been a long-standing debate about the best treatment approach for this troublesome disease. Methods and Results. Medical treatment with PPIs has an excellent efficacy in reversing the symptoms of GERD, but they should be taken for life, and long-term side effects do exist. However, patients who desire a permanent cure and have severe complications or cannot tolerate long-term treatment with PPIs are candidates for surgical treatment. Laparoscopic antireflux surgery achieves a significant symptom control, increased patient satisfaction, and complete withdrawal of antireflux medications, in the majority of patients. Conclusion. Surgical treatment should be reserved mainly for young patients seeking permanent results. However, the choice of the treatment schedule should be individualized for every patient. It is up to the patient, the physician and the surgeon to decide the best treatment option for individual cases. PMID:20069112

The barrier function of the esophageal epithelium is a major defense against gastroesophageal reflux disease. Previous studies have shown that reflux damage is reflected in a decrease in transepithelial electrical resistance associated with tight junction alterations in the esophageal epithelium. To develop novel therapies, it is critical to understand the molecular mechanisms whereby contact with a refluxate impairs esophageal barrier function. In this study, surgical models of duodenal and mixed reflux were developed in mice. Mouse esophageal epithelium was analyzed by gene microarray. Gene set enrichment analysis showed upregulation of inflammation-related gene sets and the NF-κB pathway due to reflux. Significance analysis of microarrays revealed upregulation of NF-κB target genes. Overexpression of NF-κB subunits (p50 and p65) and NF-κB target genes (matrix metalloproteinases-3 and -9, IL-1β, IL-6, and IL-8) confirmed activation of the NF-κB pathway in the esophageal epithelium. In addition, real-time PCR, Western blotting, and immunohistochemical staining also showed downregulation and mislocalization of claudins-1 and -4. In a second animal experiment, treatment with an NF-κB inhibitor, BAY 11-7085 (20 mg·kg−1·day−1 ip for 10 days), counteracted the effects of duodenal and mixed reflux on epithelial resistance and NF-κB-regulated cytokines. We conclude that gastroesophageal reflux activates the NF-κB pathway and impairs esophageal barrier function in mice and that targeting the NF-κB pathway may strengthen esophageal barrier function against reflux.

A small angle (His angle) between the oesophagus and the fundus of the stomach is considered to act as flap valve and anti-reflux barrier. A wide angle results in dysfunction of the oesophagogastric junction and subsequently in gastroesophageal reflux disease (GERD). Here, we used real-time magnetic resonance imaging (MRI) at 50 ms resolution (20 frames per second) in 12 volunteers and 12 patients with GERD to assess transport of pineapple juice through the oesophagogastric junction and reflux during Valsalva. We found that the intra-abdominal part of the oesophagus was bended towards the left side resulting in an angle of 75.3 ± 17.4, which was significantly larger during Valsava (P = 0.017). Reflux and several underlying pathologies were detected in 11 out of 12 patients. Our data visualize oesophagogastric junction physiology and disprove the flap valve hypothesis. Further, non-invasive real-time MRI has considerable potential for the diagnosis of causative pathologies leading to GERD. PMID:26175205

It has been suggested that vomiting acid gastric contents in bulimia might favor oral growth of Streptococcus sobrinus. We studied the colonization of Streptococcus sobrinus (serotypes g and d) and Streptococcus mutans (serotypes c, e and f) in sixteen children, ages five to fifteen years, who had suffered for four to eleven years from gastroesophageal reflux, another condition with recurrent acid regurgitation. Our aim was to find out if the prevalence of Streptococcus sobrinus would be higher also in this patient group. Mutants streptococci were detected in twelve out of sixteen (75 percent) study patients of the saliva samples cultured on MSB agar. For the Mutans streptococci positive children healthy controls were matched by salivary levels of mutans streptococci and age as closely as possible. From each child three to six isolates representing both Streptococcus mutans and Streptococcus sobrinus (n = 103) were serotyped by immunodiffusion method. The distribution of serotypes in the study/control group was: c: 7/10; e: 4/2; f: 0/1; g:3/2; d:0/0. One strain in the study group remained untypable. All patients infected with Streptococcus sobrinus were also infected with Streptococcus mutans. Our results indicate the great similarity in the distribution of ms serotypes in the gastroesophageal reflux children and their healthy controls. The data do not suggest that the acid regurgitation would have an influence on the prevalence of Streptococcus sobrinus.

Gastroesophageal reflux disease (GERD), a common disorder with troublesome symptoms caused by reflux of gastric contents into the esophagus, has adverse impact on quality of life. A variety of medications have been used in GERD treatment, and acid suppression therapy is the mainstay of treatment for GERD. Although proton pump inhibitor is the most potent acid suppressant and provides good efficacy in esophagitis healing and symptom relief, about one-third of patients with GERD still have persistent symptoms with poor response to standard dose PPI. Antacids, alginate, histamine type-2 receptor antagonists, and prokinetic agents are usually used as add-on therapy to PPI in clinical practice. Development of novel therapeutic agents has focused on the underlying mechanisms of GERD, such as transient lower esophageal sphincter relaxation, motility disorder, mucosal protection, and esophageal hypersensitivity. Newer formulations of PPI with faster and longer duration of action and potassium-competitive acid blocker, a newer acid suppressant, have also been investigated in clinical trials. In this review, we summarize the current and developing therapeutic agents for GERD treatment. PMID:23878534

That obesity leads to gastroesophageal reflux is a widespread notion. However, scientific evidence for this association is limited, with no rigorous epidemiological approach conducted to address this question. This study examined the relationship between body mass index (BMI) and gastroesophageal reflux symptoms in a large population-representative sample from China. We performed a cross-sectional study in an age- and gender-stratified random sample of the population of five central regions in China. Participants aged 18-80 years completed a general information questionnaire and a Chinese version of the Reflux Disease Questionnaire. The zero-inflated Poisson regression model estimated the relationship between body mass index and gastroesophageal reflux symptoms. Overall, 16,091 (89.4 %) of the 18,000 eligible participants responded. 638 (3.97 %) and 1738 (10.81 %) experienced at least weekly heartburn and weekly acid regurgitation, respectively. After adjusting for potential risk factors in the zero-inflated part, the frequency [odds ratio (OR) 0.66, 95 % confidence interval (95 % CI) 0.50-0.86, p = 0.002] and severity (OR 0.66, 95 % CI 0.50-088, p = 0.004) of heartburn in obese participants were statistically significant compared to those in normal participants. In the Poisson part, the frequency of acid regurgitation, overweight (OR 1.10, 95 % CI 1.01-1.21, p = 0.038) and obesity (OR 1.19, 95 % CI 1.04-1.37, p = 0.013) were statistically significant. BMI was strongly and positively related to the frequency and severity of gastroesophageal reflux symptoms. Additionally, gender exerted strong specific effects on the relationship between BMI and gastroesophageal reflux symptoms. The severity and frequency of heartburn were positively correlated with obesity. This relationship was presented distinct in male participants only.

Extra-esophageal gastroesophageal reflux disease and asthma: understanding this interplay.

Gastroesophageal reflux disease (GERD) is a condition that develops when there is reflux of stomach contents, which typically manifests as heartburn and regurgitation. These esophageal symptoms are well recognized; however, there are extra-esophageal manifestations of GERD, which include asthma, chronic cough, laryngitis and sinusitis. With the rising incidence of asthma, there is increasing interest in identifying how GERD impacts asthma development and therapy. Due to the poor sensitivity of endoscopy and pH monitoring, empiric therapy with proton pump inhibitors (PPIs) is now considered the initial diagnostic step in patients suspected of having GERD-related symptoms. If unresponsive, diagnostic testing with pH monitoring off therapy and/or impedance/pH monitoring on therapy, may be reasonable in order to assess for baseline presence of reflux with the former and exclude continued acid or weakly acid reflux with the latter tests. PPI-unresponsive asthmatics, without overt regurgitation, usually have either no reflux or causes other than GERD. In this group, PPI therapy should be discontinued. In those with GERD as a contributing factor acid suppressive therapy should be continued as well as optimally treating other etiologies requiring concomitant treatment. Surgical fundoplication is rarely needed but in those with a large hiatal hernia, moderate-to-severe reflux by pH monitoring surgery might be helpful in eliminating the need for high-dose acid suppressive therapy.

A detailed critique of objective measurements of gastroesophageal reflux disease (GERD) would improve management of patients suspecting of having reflux, leading to rational selection of treatment and better outcomes. Many diagnostic tests for GERD have been developed over the past decades. We analyze their development, positive- and negative-predictive values, and ability to predict response to treatment. These features are important for development of medical, surgical, and endoscopic therapies for GERD. We discuss the value of available diagnostic tests and review their role in management of patients with persistent reflux symptoms despite adequate medical or surgical treatment. This is becoming a significant health economic problem, due to the widespread use of proton pump inhibitors. GERD is believed to cause nonesophageal symptoms, such as those provoked by ear, nose, throat, or respiratory disorders. We analyze the value of GERD diagnostic tests in evaluation of these troublesome, nonesophageal symptoms. Copyright © 2018 AGA Institute. Published by Elsevier Inc. All rights reserved.

Gastroesophageal reflux disease (GERD) is associated with obesity and hiatal hernia, and often precedes the development of Barrett's esophagus (BE) and esophageal adenocarcinoma (EA). Epidemiological studies show that the global prevalence of GERD is increasing. GERD is a multifactorial disease with a complex genetic architecture. Genome-wide association studies (GWAS) have provided initial insights into the genetic background of GERD. The present review summarizes current knowledge of the genetics of GERD and a possible genetic overlap between GERD and BE and EA. The review discusses genes and cellular pathways that have been implicated through GWAS, and provides an outlook on how future molecular research will enhance understanding of GERD pathophysiology. © 2017 John Wiley & Sons Ltd.

MEIS2 aberrations are considered to be the cause of intellectual disability, cleft palate and cardiac septal defect, as MEIS2 copy number variation is often observed with these phenotypes. To our knowledge, only one nucleotide-level change-specifically, an in-frame MEIS2 deletion-has so far been reported. Here, we report a female patient with a de novo nonsense mutation (c.611C>G, p.Ser204*) in MEIS2. She showed severe intellectual disability, moderate motor/verbal developmental delay, cleft palate, cardiac septal defect, hypermetropia, severe feeding difficulties with gastro-esophageal reflux and constipation. By reviewing this patient and previous patients with MEIS2 point mutations, we found that feeding difficulty with gastro-esophageal reflux appears to be one of the core clinical features of MEIS2 haploinsufficiency, in addition to intellectual disability, cleft palate and cardiac septal defect.

Approximately 30% of patients with gastroesophageal reflux disease have symptoms resistant to treatment with proton pump inhibitors (PPIs). Several mechanisms such as esophageal hypersensitivity, increased mucosal permeability, and possibly the position of the gastric acid pocket might underlie a partial response to PPIs. To what extent these mechanisms interact and contribute to PPI-resistant symptoms, however, has not been investigated previously. In 18 gastroesophageal reflux disease patients (9 PPI responders and 9 PPI partial responders), esophageal sensitivity, mucosal permeability, and postprandial reflux parameters were determined during PPI use. Esophageal sensitivity for distension was measured by gradual balloon inflation at 5 and 15 cm above the lower esophageal sphincter. The mucosal permeability of 4 esophageal biopsy specimens per patient was determined in Ussing chambers by measuring the transepithelial electrical resistance and transmucosal flux of fluorescein. Postprandial reflux parameters were determined using concurrent high-resolution manometry/pH impedance after a standardized meal. In addition, the acid pocket was visualized using scintigraphy. No difference in the rate of postprandial acid reflux, in the pH of the acid pocket (PPI responders 3.7 ± 0.7 vs PPI partial responders 4.2 ± 0.4; P = .54), or in the position of the acid pocket was observed in PPI partial responders compared with PPI responders. In addition, the permeability of the esophageal mucosa was similar in both groups, as shown by a similar transepithelial electrical resistance and flux of fluorescein. PPI partial responders had more reflux episodes with a higher mean proximal extent, compared with PPI responders, and were more sensitive to balloon distension, both in the upper and lower esophagus. PPI-resistant symptoms most likely are explained by increased proximal reflux in a hypersensitive esophagus and less likely by increased mucosal permeability or the position of

Limited data exist regarding the psychosocial aspects of gastroesophageal reflux disease (GERD). Some GERD subgroups, such as functional heartburn and hypersensitive esophagus, might show different psychiatric comorbidities than others. We aimed to evaluate the psychiatric comorbidities of GERD subgroups using a cross-sectional design. A group of GERD patients at a tertiary outpatient clinic were evaluated via upper GIS (gastrointestinal system) endoscopy, esophageal manometry, and 24-h impedance-pH monitoring. Thirty-nine patients diagnosed with erosive reflux disease, 44 with non-erosive reflux disease, 20 with functional heartburn, 11 with hypersensitive esophagus, and 44 healthy controls participated. Psychiatric diagnoses were made using the Structured Clinical Interview for Diagnostics and Statistical Manual of Mental Disorders IV. Psychometric measurements of the patients were performed using the Somatosensory Amplification Scale, Beck Depression Inventory, State-Trait Anxiety Inventory, and Short-Form 36. Healthy controls were evaluated with the same psychometric scales except for the Short-Form 36. All of the GERD subgroups were significantly more depressed than the control group. Depressive disorders were significantly more prevalent in the functional heartburn group than in the non-erosive reflux disease and erosive reflux disease groups. The trait anxiety level of the functional heartburn group was significantly higher than those of the control and non-erosive reflux disease groups. The quality of life scores of the GERD subgroups were significantly lower than the population standards. Depressive disorders were frequently comorbid in the GERD subgroups studied (30-65 %). It is essential to consider the high prevalence rates of comorbid depression when managing GERD.

The patients treated for oesophageal atresia present a correlation between the clinical sintomatology after recanalization characterized by disfagia, dispnea, recurrent cough, chronic pneumopaties and oesophageal anomalies. Where morphological alterations accounting for the presence of gastro-oesophageal reflux (GOR) were not evident, possible functional alterations of the motility were considered. The incidence of GOR was considerably high and, expression of a congenital alteration of the lower oesophageal sphincter and of oesophageal peristalsis, becomes even more severe due to further stretching of the gastro-esophageal junction. The authors underline that the early demonstration of histological changes, even before recanalization, and the motility disorders of the oesophagus have to be well studied, while the LES is normalized, in order to prevent and treat the possible appearance of the well-known complications of GOR.

The study aimed at developing a scoring system for scintigraphic grading of gastro-esophageal reflux (GER), on gastro-esophageal reflux scintigraphy (GERS) and comparison of clinical and scintigraphic scores, pre- and post-treatment. A total of 39 cases with clinically symptomatic GER underwent 99mTc sulfur colloid GERS; scores were assigned based on the clinical and scintigraphic parameters. Post domperidone GERS was performed after completion of treatment. Follow up GERS was performed and clinical and scintigraphic parameters were compared with baseline parameters. Paired t-test on pre and post domperidone treatment clinical scores showed that the decline in post-treatment scores was highly significant, with P value < 0.001. The scintigraphic scoring system had a sensitivity of 93.9% in assessing treatment response to domperidone, specificity of 83.3% i.e., 83.3% of children with no decline in scintigraphic scores show no clinical response to Domperidone. The scintigraphic scoring system had a positive predictive value of 96.9% and a negative predictive value of 71.4%. GERS with its quantitative parameters is a good investigation for assessing the severity of reflux and also for following children post-treatment.

Gastroesophageal reflux disease (GERD) is a common chronic disorder that is associated with a huge economic burden in the western countries and significantly decreased quality of life. This review focuses on the various multicultural issues in the epidemiology, pathophysiology, diagnosis, and treatment of GERD. The prevalence of GERD appears to be highest in North America and Europe, whereas epidemiologic data from the Indian subcontinent, Africa, South America, and the Middle East are sparse. A limited number of studies have elucidated ethnic differences in GERD in multiracial populations. African Americans and Asians appear to be at a lower risk for the development of complicated GERD including Barrett's esophagus (BE). Whether the pathophysiology of GERD differs among different populations remains to be answered satisfactorily. It appears that most of the factors involved in the pathogenesis of GERD, as described in western populations, are present in Asians but at a lower scale. The current recommendations for the management of GERD by the American College of Gastroenterology may not meet the need for different ethnic groups or for different geographic regions. Recognition of language barriers in understanding the common terms used to describe reflux symptoms should be borne in mind while treating GERD patients with different ethnic backgrounds. In addition, a universally accepted definition for treatment success in GERD patients is lacking. Given the negative impact on health-related quality of life, significant cost ramifications, and increased risk for BE and esophageal adenocarcinoma, the study of multicultural issues in GERD should be considered.

Little is known about non-acid gastroesophageal reflux-induced chronic cough (GERC). The purpose of the study is to explore the clinical characteristics of non-acid GERC. Clinical symptoms, cough symptom score, capsaicin cough sensitivity, gastroesophageal reflux diagnostic questionnaire (GerdQ) score, findings of multichannel intraluminal impedance-pH monitoring (MII-pH) and response to pharmacological anti-reflux therapy were retrospectively reviewed in 38 patients with non-acid GERC and compared with those of 49 patients with acid GERC. Non-acid GERC had the similar cough character, cough symptom score, and capsaicin cough sensitivity to acid GERC. However, non-acid GERC had less frequent regurgitation (15.8% vs 57.1%, χ(2)  = 13.346, P = 0.000) and heartburn (7.9% vs 32.7%, χ(2)  = 7.686, P  = 0.006), and lower GerdQ score (7.4 ± 1.4 vs 10.6 ± 2.1, t = -6.700, P = 0.003) than acid GERC. Moreover, MII-pH revealed more weakly acidic reflux episodes, gas reflux episodes and a higher symptom association probability (SAP) for non-acid reflux but lower DeMeester score, acidic reflux episodes and SAP for acid reflux in non-acid GERC than in acid GERC. Non-acid GERC usually responded to the standard anti-reflux therapy but with delayed cough resolution or attenuation when compared with acid GERC. Fewer patients with non-acid GERC needed an augmented acid suppressive therapy or treatment with baclofen. There are some differences in the clinical manifestations between non-acid and acid GERC, but MII-pH is essential to diagnose non-acid GERC. © 2014 John Wiley & Sons Ltd.

Our aim was to assess the association of a Mediterranean diet and gastroesophageal reflux disease among adult men and women in Albania, a former communist country in South Eastern Europe with a predominantly Muslim population. A cross-sectional study was conducted in 2012, which included a population-based sample of 817 individuals (≥18 years) residing in Tirana, the Albanian capital (333 men; overall mean age: 50.2 ± 18.7 years; overall response rate: 82%). Assessment of gastroesophageal reflux disease was based on Montreal definition. Participants were interviewed about their dietary patterns, which in the analysis was dichotomized into: predominantly Mediterranean (frequent consumption of composite/traditional dishes, fresh fruit and vegetables, olive oil, and fish) versus largely non-Mediterranean (frequent consumption of red meat, fried food, sweets, and junk/fast food). Logistic regression was used to assess the association of gastroesophageal reflux disease with the dietary patterns. Irrespective of demographic and socioeconomic characteristics and lifestyle factors including eating habits (meal regularity, eating rate, and meal-to-sleep interval), employment of a non-Mediterranean diet was positively related to gastroesophageal reflux disease risk (fully adjusted odds ratio = 2.3, 95% confidence interval = 1.2-4.5). Our findings point to a beneficial effect of a Mediterranean diet in the occurrence of gastroesophageal reflux disease in transitional Albania. Findings from this study should be confirmed and expanded further in prospective studies in Albania and in other Mediterranean countries. © 2015 International Society for Diseases of the Esophagus.

Duodenal ulcer and gastroesophageal reflux disease today: long-term therapy--a sideways glance.

PubMed Central

Bardhan, K. D.

1996-01-01

Acid-peptic disease is widely considered conquered or controlled, future advances being refinements of existing treatments rather than radical new developments. Yet controversies remain and developments have yet to be made. DUODENAL ULCER: Daily maintenance treatment with the anti-secretory drugs, histamine H2 receptor antagonists and proton pump blockers, controls duodenal ulcer effectively, markedly reducing relapse rate at one year after treatment from about 75 percent to 15 to 20 percent (and to about 10 percent on proton pump blockers). In contrast, Helicobacter pylori eradication with a one to two week course of treatment yields prolonged remission or cure. The consequent reduction in drug costs in individual patients, however, has been exceeded by increasing community use on the more expensive proton pump blockers for the treatment of gastroesophageal reflux disease. The marked decline in elective surgery since the introduction of histamine H2 receptor antagonists is commonly attributed to the power of these drugs. The fall, however, had started much earlier, indicating that the decline is due to changing natural history. In contrast, complication rates remain unaltered. An increasing proportion of newly diagnosed duodenal ulcer patients are elderly, and more of them now present for the first time with complications (in this center, about 40 percent), which consequently cannot be forestalled. Thus, duodenal ulcer disease is likely to remain a problem and in many will be a serious illness. GASTROESOPHAGEAL REFLUX DISEASE: The proton pump blockers have revolutionized the treatment of gastroesophageal reflux disease. In clinical trials they have proven markedly superior to the histamine H2 receptor antagonists in healing (at eight weeks, 80 to 90 percent vs. 50 to 60 percent), symptom relief, prevention of relapse on maintenance therapy and cost-effectiveness. However, several issues remain. The prevalence of gastroesophageal reflux disease seems to be rising

Although gastroesophageal reflux disease (GERD) is a common disorder in Western countries, with a significant impact on quality of life and healthcare costs, the mechanisms involved in the pathogenesis of symptoms remain to be fully elucidated. GERD symptoms and complications may result from a multifactorial mechanism, in which acid and acid-pepsin are the important noxious factors involved. Prolonged contact of the esophageal mucosa with the refluxed content, probably caused by a defective anti-reflux barrier and luminal clearance mechanisms, would appear to be responsible for macroscopically detectable injury to the esophageal squamous epithelium. Receptors on acid-sensitive nerve endings may play a role in nociception and esophageal sensitivity, as suggested in animal models of chronic acid exposure. Meanwhile, specific cytokine and chemokine profiles would appear to underlie the various esophageal phenotypes of GERD, explaining, in part, the genesis of esophagitis in a subset of patients. Despite these findings, which show a significant production of inflammatory mediators and neurotransmitters in the pathogenesis of GERD, the relationship between the hypersensitivity and esophageal inflammation is not clear. Moreover, the large majority of GERD patients (up to 70%) do not develop esophageal erosions, a variant of the condition called non-erosive reflux disease. This summary aims to explore the inflammatory pathway involved in GERD pathogenesis, to better understand the possible distinction between erosive and non-erosive reflux disease patients and to provide new therapeutic approaches.

A randomized controlled trial conducted in patients with gastroesophageal reflux disease compared optimized medical therapy using proton pump inhibitor (n = 52) with laparoscopic Nissen fundoplication (n = 52). Patients were monitored for 1 year. The primary end point was frequency of gastroesophageal reflux dis-ease symptoms. Surgical patients had improved symptoms, pH control, and overall quality of life health index after surgery at 1 year compared with the medical group. The overall gastroesophageal reflux disease symptom score at 1 year was unchanged in the medical patients, but improved in the surgical patients. Fourteen patients in the medical arm experienced symptom relapse requiring titration of the proton pump inhibitor dose, but 6 had satisfactory symptom remission. No surgical patients required additional treatment for symptom control. Patients controlled on long-term proton pump inhibitor therapy for chronic gastroesophageal reflux disease are excellent surgical candidates and should experience improved symptom control after surgery at 1 year.

Neurologically impaired patients frequently suffer from gastrointestinal tract problems, such as gastroesophageal reflux disease (GERD). In this study, we aimed to define the risk factors for GERD in neurologically impaired children. From May 2006 to March 2014, 101 neurologically impaired children who received 24-hour esophageal pH monitoring at Severance Children's Hospital were enrolled in the study. The esophageal pH finding and the clinical characteristics of the patients were analyzed. The reflux index was higher in patients with abnormal electroencephalography (EEG) results than in those with normal EEG results (p=0.027). Mitochondrial disease was associated with a higher reflux index than were epileptic disorders or cerebral palsy (p=0.009). Patient gender, feeding method, scoliosis, tracheostomy, and baclofen use did not lead to statistical differences in reflux index. Age of onset of neurological impairment was inversely correlated with DeMeester score and reflux index. Age at the time of examination, the duration of the disease, and the number of antiepileptic drugs were not correlated with GER severity. Early-onset neurological impairment, abnormal EEG results, and mitochondrial disease are risk factors for severe GERD.

Background/Aims Globus is a foreign body sense in the throat without dysphagia, odynophagia, esophageal motility disorders, or gastroesophageal reflux. The etiology is unclear. Previous studies suggested that increased upper esophageal sphincter pressure, gastroesophageal reflux and hypertonicity of esophageal body were possible etiologies. This study was to quantify the upper esophageal sphincter (UES) pressure, contractile front velocity (CFV), proximal contractile integral (PCI), distal contractile integral (DCI) and transition zone (TZ) in patient with globus gastroesophageal reflux disease (GERD) without globus, and normal controls to suggest the correlation of specific high-resolution manometry (HRM) findings and globus. Methods Fifty-seven globus patients, 24 GERD patients and 7 normal controls were studied with HRM since 2009. We reviewed the reports, and selected 5 swallowing plots suitable for analysis in each report, analyzed each individual plot with ManoView. The 5 parameters from each plot in 57 globus patients were compared with that of 24 GERD patients and 7 normal controls. Results There was no significant difference in the UES pressure, CFV, PCI and DCI. TZ (using 30 mmHg isobaric contour) in globus showed significant difference compared with normal controls and GERD patients. The median values of TZ were 4.26 cm (interquartile range [IQR], 2.30-5.85) in globus patients, 5.91 cm (IQR, 3.97-7.62) in GERD patients and 2.26 cm (IQR, 1.22-2.92) in normal controls (P = 0.001). Conclusions HRM analysis suggested that UES pressure, CFV, PCI and DCI were not associated with globus. Instead increased length of TZ may be correlated with globus. Further study comparing HRM results in globus patients within larger population needs to confirm their correlation. PMID:24199007

In patients with gastroesophageal reflux disease (GERD) and excessive belching, most belches are supragastric, and can induce reflux episodes and worsen GERD. Supragastric belching (SGB) might be reduced with diaphragmatic breathing exercises. We investigated whether diaphragmatic breathing therapy is effective in reducing belching and proton pump inhibitor (PPI)-refractory gastroesophageal reflux symptoms. We performed a prospective study of 36 consecutive patients with GERD refractory to PPI therapy and a belching visual analogue scale (VAS) score of 6 or more, seen at a gastroenterology clinic at a tertiary hospital in Singapore from April 2015 through October 2016. Patients underwent high-resolution manometry and 24-hour pH-impedance studies while they were off PPIs. Fifteen patients were placed on a standardized diaphragmatic breathing exercise protocol (treatment group) and completed questionnaires at baseline, after diaphragmatic breathing therapy, and 4 months after the therapy ended. Twenty-one patients were placed on a waitlist (control subjects), completed the same questionnaires with an additional questionnaire after their waitlist period, and eventually received diaphragmatic breathing therapy. The primary outcome was reduction in belching VAS by 50% or more after treatment. Secondary outcomes included GERD symptoms (evaluated using the reflux disease questionnaire) and quality of life (QoL) scores, determined from the Reflux-Qual Short Form and EuroQoL-VAS. Nine of the 15 patients in the treatment group (60%) and none of the 21 control subjects achieved the primary outcome (P < .001). In the treatment group, the mean belching VAS score decreased from 7.1 ± 1.5 at baseline to 3.5 ± 2.0 after diaphragmatic breathing therapy; in the control group, the mean VAS score was 7.6 ± 1.1 at baseline and 7.4 ± 1.3 after the waitlist period. Eighty percent of patients in the treatment group significantly reduced belching frequency compared with 19% in control

We updated the 2006 ACCP clinical practice guidelines for management of reflux-cough syndrome. Two population, intervention, comparison, outcome (PICO) questions were addressed by systematic review: (1) Can therapy for gastroesophageal reflux improve or eliminate cough in adults with chronic and persistently troublesome cough? and (2) Are there minimal clinical criteria to guide practice in determining that chronic cough is likely to respond to therapy for gastroesophageal reflux? We found no high-quality studies pertinent to either question. From available randomized controlled trials (RCTs) addressing question #1, we concluded that (1) there was a strong placebo effect for cough improvement; (2) studies including diet modification and weight loss had better cough outcomes; (3) although lifestyle modifications and weight reduction may be beneficial in suspected reflux-cough syndrome, proton pump inhibitors (PPIs) demonstrated no benefit when used in isolation; and (4) because of potential carryover effect, crossover studies using PPIs should be avoided. For question #2, we concluded from the available observational trials that (1) an algorithmic approach to management resolved chronic cough in 82% to 100% of instances; (2) cough variant asthma and upper airway cough syndrome (UACS) (previously referred to as postnasal drip syndrome) from rhinosinus conditions were the most commonly reported causes; and (3) the reported prevalence of reflux-cough syndrome varied widely. The panelists (1) endorsed the use of a diagnostic/therapeutic algorithm addressing causes of common cough, including symptomatic reflux; (2) advised that although lifestyle modifications and weight reduction may be beneficial in suspected reflux-cough syndrome, PPIs demonstrated no benefit when used in isolation; and (3) suggested that physiological testing be reserved for refractory patients being considered for antireflux surgery or for those in whom there is strong clinical suspicion

The purpose of this study was to describe the type and quality of health information about infant gastroesophageal reflux (GER) that a parent may find on the World Wide Web. The data collection tool included evaluation of Web site quality and infant GER-specific content on the 30 sites that met the inclusion criteria. The most commonly found content categories in order of frequency were management strategies, when to call a primary care provider, definition, and clinical features. The most frequently mentioned strategies included feeding changes, infant positioning, and medications. Thirteen of the 30 Web sites included information on both GER and gastroesophageal reflux disease. Mention of the use of medication to lessen infant symptoms was found on 15 of the 30 sites. Only 10 of the 30 sites included information about parent support and coping strategies. Pediatric nurse practitioners (PNPs) should utilize well-child visits to address the normalcy of physiologic infant GER and clarify any misperceptions parents may have about diagnosis and the role of medication from information they may have found on the Internet. It is critical for PNPs to assist in the development of Web sites with accurate content, advise parents on how to identify safe and reliable information, and provide examples of high-quality Web sites about child health topics such as infant GER.

BACKGROUND Reflux disease is a common gastrointestinal problem. The association between reflux disease and gastritis pattern is controversial. To determine the association between reflux disease and gastritis pattern in patients with Helicobacter pylori (H. pylori) infection. METHODS 470 patients with dyspepsia and reflux disease were enrolled in this study. The inclusion criteria were willing to participate in the study, age over 40 years, and having the criteria of ROME III for at least 3 months. Patients with history of H. pylori eradication therapy during the 3 months before the study, a history of gastric surgery, and gastric cancer were excluded. All of the participants underwent upper endoscopy and two biopsy samples were taken from antrum, body, and fundal areas. RESULTS H. pylori infection rate was 367 (78.1%) with mean age of 59.8 ± 11.4 years. Of them 131 patients (35.7%) were male. Reflux disease was detected in 273 (74.4%) patients. 216 (58.9%) and 102 (27.8%) patients had non-erosive reflux disease (NERD) and gastroesophageal reflux disease (GERD), respectively. Corpus predominant and antral predominant gastritis were seen in 72 (19.6%) and 129 (35.2%) patients, respectively. Antral gastritis was significantly associated with GERD ( p <0.01). In regression analysis, antral predominant gastritis had a significant association with GERD (OR=1.92; 95%CI: 1.22- 3.12). The same result was observed in mild to moderate antral and greater curvature gastritis (OR= 1.26; 95%CI: 0.25-6.40 and OR= 3.0; 95%CI: 0.63-14.17, respectively). CONCLUSION According to these finding ,we could suggest that the pattern of gastritis could be associated with reflux disease and GERD.

With the availability of a minimally invasive approach, anti-reflux surgery has recently experienced a renaissance as a cost-effective alternative to life-long medical treatment in patients with gastroesophageal reflux disease (GERD). We are not aware of the fact whether reflux episodes causing complaints for a long time i.e., at least for one year are associated with metabolic changes in the lower esophageal sphincter, and if so, whether these may influence functional results achieved after anti-reflux surgery. Between 1 January 2001 and 31 December 2002 we performed anti-reflux surgery on 79 patients. Muscle samples were taken from the lower esophageal sphincter (LES) in 33 patients during anti-reflux surgery. Inclusion criteria were: LES resting pressure below 10 mmHg and a marked, pH proven acid exposure to the esophagus of at least one year's duration, causing subjective complaints and requiring continuous proton pump inhibitor treatment. Control samples were obtained from muscle tissue in the gastroesophageal junction that had been removed from 17 patients undergoing gastric or esophageal resection. Metabolic and lysosomal enzyme activities and special protein concentrations 16 parameters in total were evaluated in tissue taken from control specimens and tissue taken from patients with GERD. The biochemical parameters of these intra-operative biopsies were used to correlate the results of anti-reflux operations (Visick I and II-III). In the reflux-type muscle, we found a significant increase of the energy-enzyme activities e.g., creatine kinase, lactate dehydrogenase, beta-hydroxybutyrate dehydrogenase, and aspartate aminotransaminase-. The concentration of the structural protein S-100 and the myofibrillar protein troponin I were also significantly increased. Among lysosomal enzymes, we found that the activities of cathepsin B, tripeptidyl-peptidase I, dipeptidyl-peptidase II, beta-hexosaminidase B, beta-mannosidase and beta-galactosidase were significantly

Gastroesophageal reflux disease: an Asian perspective.

PubMed

Wu, Justin C Y

2008-12-01

The prevalence of gastroesophageal reflux disease (GERD) ranges from 2.5% to 7.1% in most population-based studies in Asia. There is evidence that GERD and its complications are rising, coinciding with a decline in Helicobacter pylori (H. pylori) infection. Asian GERD patients share similar risk factors and pathophysiological mechanisms with their Western counterparts. Possible causes for the lower prevalence of GERD include less obesity and hiatus hernia, a lesser degree of esophageal dysmotility, a high prevalence of virulent strains of H. pylori, and low awareness. Owing to the lack of precise translation for 'heartburn' in most Asian languages, reflux symptoms are often overlooked or misinterpreted as dyspepsia or chest pain. Furthermore, a symptom-based diagnosis with a therapeutic trial of the proton pump inhibitor (PPI) may be hampered by the high prevalence of H. pylori-related disease. The risk stratification for prompt endoscopy, use of a locally-validated, diagnostic symptom questionnaire, and response to H. pylori'test and treat' help improve the accuracy of the PPI test for diagnoses. PPI remain the gold standard treatment, and 'on-demand' PPI have been shown to be a cost-effective, long-term treatment. The clinical course of GERD is benign in most patients in Asia. The risk of progression from non-erosive reflux disease to erosive esophagitis is low, and treatment response to a conventional dose of PPI is generally higher. Although H. pylori eradication may lead to more resilient GERD in a subset of patients, the benefits of H. pylori eradication outweigh the risks, especially in Asian populations with a high incidence of gastric cancer.

To quantify normal proximal and distal oesophageal acid parameters in healthy Chinese. Observational study. University teaching hospital, Hong Kong. Twenty healthy adults who were not on medication and were free from gastrointestinal symptoms were recruited by advertisement. Ambulatory oesophageal acid (pH<4) exposure parameters were recorded at distal and proximal sites, 5 and 20 cm, respectively above the lower oesophageal sphincter. The 95th percentile for reflux parameters assessed in the distal/proximal oesophagus were: percent total time pH<4, 4.6/0.7%; percent upright time pH<4, 7.0/1.1%; percent supine time pH<4, 4.5/0.5%; number of reflux episodes, 73/12; number of reflux episodes with pH<4 for >5 minutes, 4/0; and the longest single acid exposure episode, 11.2/3.0 minutes. Physiological gastroesophageal reflux occurs in healthy Chinese. These initial data provide a preliminary reference range that could be utilised by laboratories studying Chinese subjects.

Esophageal adenocarcinoma (EA) is a rapidly fatal cancer with rising incidence in the developed world. Most EAs arise in a metaplastic epithelium, Barrett's esophagus (BE), which is associated with greatly increased risk of EA. One of the key risk factors for both BE and EA is chronic gastroesophageal reflux disease (GERD). This study used the linkage disequilibrium (LD) score regression and genomic profile risk scoring approaches to investigate the contribution of multiple common single-nucleotide polymorphisms (SNPs) to the risk of GERD, and the extent of genetic overlap between GERD and BE or EA. Using LD score regression, we estimated an overall phenotypic variance of 7% (95% CI 3–11%) for GERD explained by all the genotyped SNPs. A genetic correlation of 77% (s.e. = 24%, P = 0.0012) between GERD and BE and 88% between GERD and EA (s.e. = 25%, P = 0.0004) was estimated using the LD score regression approach. Results from the genomic profile risk scoring approach, as a robustness check, were broadly similar to those from the LD score regression. This study provides the first evidence for a polygenic basis for GERD and supports for a polygenic overlap between GERD and BE, and GERD and EA. PMID:26704365

Gastroesophageal reflux disease (GERD) has a large economic burden with important complications that include esophagitis, Barrett's esophagus, and adenocarcinoma. Despite endoscopy, validated patient questionnaires, and traditional ambulatory pH monitoring, the diagnosis of GERD continues to be challenging. Areas covered: This review will explore the difficulties in diagnosing GERD with a focus on new developments, ranging from basic fundamental changes (histology and immunohistochemistry) to direct patient care (narrow-band imaging, impedance, and response to anti-reflux surgery). We searched PubMed using the noted keywords. We included data from full-text articles published in English. Further relevant articles were identified from the reference lists of review articles. Expert commentary: Important advances in novel parameters in intraluminal impedance monitoring such as baseline impedance monitoring has created some insight into alternative diagnostic strategies in GERD. Recent advances in endoscopic assessment of esophageal epithelial integrity via mucosal impedance measurement is questioning the paradigm of prolonged ambulatory testing for GERD. The future of reflux diagnosis may very well be without the need for currently employed technologies and could be as simple as assessing changes in epithelia integrity as a surrogate marker for GERD. However, future studies must validate such an approach.

Although gastroesophageal reflux disease is not as common in Asia as in western countries, the prevalence has increased substantially during the past decade. Gastroesophageal reflux disease is associated with considerable reductions in subjective well-being and work productivity, as well as increased healthcare use. Proton pump inhibitors (PPIs) are currently the most effective treatment for gastroesophageal reflux disease. However, there are limitations associated with these drugs in terms of partial and non-response. Dexlansoprazole is the first PPI with a dual delayed release formulation designed to provide 2 separate releases of medication to extend the duration of effective plasma drug concentration. Dexlansoprazole has been shown to be effective for healing of erosive esophagitis, and to improve subjective well-being by controlling 24-hour symptoms. Dexlansoprazole has also been shown to achieve good plasma concentration regardless of administration with food, providing flexible dosing. Studies in healthy volunteers showed no clinically important effects on exposure to the active metabolite of clopidogrel or clopidogrel-induced platelet inhibition, with no dose adjustment of clopidogrel necessary when coprescribed. This review discusses the role of the new generation PPI, dexlansoprazole, in the treatment of gastroesophageal reflux disease in Asia.

Gastroesophageal reflux disease (GERD) is the most prevalent gastrointestinal disorder in the United States, and leads to substantial morbidity, though associated mortality is rare. The prevalence of GERD symptoms appeared to increase until 1999. Risk factors for complications of GERD include advanced age, male sex, white race, abdominal obesity, and tobacco use. Most patients with GERD present with heartburn and effortless regurgitation. Coexistent dysphagia is considered an alarm symptom, prompting evaluation. There is substantial overlap between symptoms of GERD and those of eosinophilic esophagitis, functional dyspepsia, and gastroparesis, posing a challenge for patient management.

Since then, no further families have been described. To study a new Portuguese family with these characteristics. To describe the clinical and neurophysiologic characteristics of one family with features of sensory neuropathy associated with cough and gastroesophageal erflux. Three of five siblings presented a similar history of paroxysmal cough (5th decade). About a decade later they experienced numbness and paraesthesia in the feet and in all cases there was evidence of an axonal sensory neuropathy. A history of gastroesophageal reflux of variable severity and age of onset was also present. Molecular genetic studies have demonstrated genetic heterogeneity between the hereditary sensory neuropathy type 1 subtypes. The identification of these families is of major importance because further work is required to identify the underlying genetic defect.

Twenty-four-hour esophageal impedance-pH monitoring in healthy preterm neonates: rate and characteristics of acid, weakly acidic, and weakly alkaline gastroesophageal reflux.

Gastroesophageal reflux is a physiologic process and is considered pathologic (gastroesophageal reflux disease) when it causes symptoms or results in complications. It is common in preterm infants and occurs in healthy neonates. Twenty-four-hour pH monitoring commonly is used in children for diagnosis of gastroesophageal reflux disease, and abnormal reflux is considered with detection of increased esophageal acid exposure. However, in neonates, relatively few gastroesophageal reflux episodes cause esophageal acidification to pH < 4. Premature infants receive frequent feeds, which can induce a weaker acid secretory response than that observed in older infants and adults. As a consequence, gastric pH may be > 4 for prolonged periods, and reflux of gastric contents might be less acidic or even alkaline. Esophageal impedance monitoring can detect weakly acidic and even alkaline gastroesophageal reflux. The role of weakly acidic reflux in the pathophysiology of gastroesophageal reflux disease in preterm infants is not clear. To date, studies that have used impedance-pH in neonates assessed the association between nonacid reflux and cardiorespiratory symptoms, but no impedance data from healthy preterm neonates have been available to determine whether those symptomatic neonates had an increased number of weakly acidic reflux episodes or increased reactivity to a physiologic number of reflux events. Our aim with this study was to provide impedance-pH values for acid, weakly acidic, and weakly alkaline reflux from healthy preterm neonates. Esophageal impedance was recorded for 24 hours in 21 asymptomatic preterm neonates by replacing the conventional feeding tube with a specially designed feeding tube that included 9 impedance electrodes (8 French). All neonates were asymptomatic, with spontaneous breathing. Reflux monitoring was performed after comprehensive explanation and on receipt of written parental consent. Esophageal and gastric pH were monitored using a separate

Management of failure after surgery for gastro-esophageal reflux disease.

Surgical treatment of gastro-esophageal reflux disease (ST-GERD) is well-codified and offers an alternative to long-term medical treatment with a better efficacy for short and long-term outcomes. However, failure of ST-GERD is observed in 2-20% of patients; management is challenging and not standardized. The aim of this study is to analyze the causes of failure and to provide a treatment algorithm. The clinical aspects of ST-GERD failure are variable including persistent reflux, dysphagia or permanent discomfort leading to an important degradation of the quality of life. A morphological and functional pre-therapeutic evaluation is necessary to: (i) determine whether the symptoms are due to recurrence of reflux or to an error in initial indication and (ii) to understand the cause of the failure. The most frequent causes of failure of ST-GERD include errors in the initial indication, which often only need medical treatment, and surgical technical errors, for which surgical redo surgery can be difficult. Multidisciplinary management is necessary in order to offer the best-adapted treatment. Copyright © 2018. Published by Elsevier Masson SAS.

Few studies have examined the incidence of complications from gastro-esophageal reflux disease (GERD) in children and adolescents in primary care. Here we aimed to describe the natural history of GERD in a pediatric population with no reflux esophagitis at initial diagnosis, assessing diagnoses of new esophageal complications and extra-esophageal conditions. We used The Health Improvement Network UK primary care database (which includes data on more than 2 million patients) to identify individuals aged 1-17 years with a first diagnosis of gastro-esophageal reflux or heartburn in the period 2000-2005, via a computerized search followed by a manual review of the patient records. This search identified 1242 individuals with an incident diagnosis of GERD but no record of esophagitis. This cohort was followed-up to detect new diagnoses of esophageal complications and extra-esophageal conditions. During a mean follow-up period of almost 4 years, 40 children and adolescents had a confirmed new diagnosis of reflux esophagitis (incidence: 10.9 per 1000 person-years). No cases of Barrett's esophagus, esophageal stricture or esophageal ulcer were reported. Individuals with GERD had double the risk of an extra-esophageal condition such as asthma, pneumonia, cough or chest pain compared with children and adolescents with no diagnosis of GERD. Children and adolescents with GERD may be at risk of developing reflux esophagitis and a range of other extra-esophageal conditions, but more severe esophageal complications are rare.

Gastro-esophageal reflux disease is a troublesome disease for many patients, severely affecting their quality of life. Choice of treatment depends on a combination of patient characteristics and preferences, esophageal motility and damage of reflux, symptom severity and symptom correlation to acid reflux and physician preferences. Success of treatment depends on tailoring treatment modalities to the individual patient and adequate selection of treatment choice. PubMed, Embase, The Cochrane Database of Systematic Reviews, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched for systematic reviews with an abstract, publication date within the last five years, in humans only, on key terms (laparosc* OR laparoscopy*) AND (fundoplication OR reflux* OR GORD OR GERD OR nissen OR toupet) NOT (achal* OR pediat*). Last search was performed on July 23nd and in total 54 articles were evaluated as relevant from this search. The laparoscopic Toupet fundoplication is the therapy of choice for normal-weight GERD patients qualifying for laparoscopic surgery. No better pharmaceutical, endoluminal or surgical alternatives are present to date. No firm conclusion can be stated on its cost-effectiveness. Results have to be awaited comparing the laparoscopic 180-degree anterior fundoplication with the Toupet fundoplication to be a possible better surgical alternative. Division of the short gastric vessels is not to be recommended, nor is the use of a bougie or a mesh in the vast majority of GERD patients undergoing surgery. The use of a robot is not recommended. Anti-reflux surgery is to be considered expert surgery, but there is no clear consensus what is to be called an 'expert surgeon'. As for setting, ambulatory settings seem promising although high-level evidence is lacking. Copyright © 2013 Elsevier Ltd. All rights reserved.

We encountered 3 patients with severe gastroesophageal reflux disease and tubular stomachs precluding fundoplication. Here, we report the use of an innovative technique, cardiaplication, as an alternative approach for antireflux surgery. Three infants with medically refractory gastroesophageal reflux disease (GERD) were referred for fundoplication. In each case, the patient's anatomy prevented a traditional fundoplication from being performed. A cardiaplication was performed by invaginating the cardia of the stomach at the angle of His and securing the invaginated tissue with interrupted silk suture. The plication tubularized the cardia of the stomach, essentially increasing the intra-abdominal portion of the esophagus and altering the angle of His. The imbrication also creates a flapper valve over the distal esophagus, further limiting potential reflux. The charts for the infants who received cardiaplication were reviewed. Radiographic studies and clinical notes for the presence of persistent reflux were evaluated. Cardiaplication was completed in 3 patients with GERD. All cases were initiated laparoscopically and one was converted to an open procedure secondary to dense adhesive disease. Each child was initiated on feeds between postoperative day 2 and 3. Two of the 3 patients were tolerating goal feeds with-in 2 days. The third patient reached goal feeds on day 16. Postoperative imaging (upper gastrointestinal series [UGI]) was obtained in 2 of the 3 patients. At follow-up (13, 7, and 4 months), all 3 patients are clinically free of symptoms of GERD. Delayed radiographic imaging has confirmed that the patients are no longer refluxing. Based on preliminary findings, cardiaplication appears to be a safe and effective surgical technique for the management of severe GERD in infants. We performed cardiaplication out of necessity; however, after further testing this may prove to be an optimal approach, as it can be performed without disruption of the hiatus.

Although gastroesophageal reflux disease is not as common in Asia as in western countries, the prevalence has increased substantially during the past decade. Gastroesophageal reflux disease is associated with considerable reductions in subjective well-being and work productivity, as well as increased healthcare use. Proton pump inhibitors (PPIs) are currently the most effective treatment for gastroesophageal reflux disease. However, there are limitations associated with these drugs in terms of partial and non-response. Dexlansoprazole is the first PPI with a dual delayed release formulation designed to provide 2 separate releases of medication to extend the duration of effective plasma drug concentration. Dexlansoprazole has been shown to be effective for healing of erosive esophagitis, and to improve subjective well-being by controlling 24-hour symptoms. Dexlansoprazole has also been shown to achieve good plasma concentration regardless of administration with food, providing flexible dosing. Studies in healthy volunteers showed no clinically important effects on exposure to the active metabolite of clopidogrel or clopidogrel-induced platelet inhibition, with no dose adjustment of clopidogrel necessary when coprescribed. This review discusses the role of the new generation PPI, dexlansoprazole, in the treatment of gastroesophageal reflux disease in Asia. PMID:26932927

Transient lower esophageal sphincter relaxation (TLESR) is the main mechanism of gastroesophageal reflux disease (GERD). The aim of this study was to investigate the characteristics of transient lower esophageal sphincter movement in patients with or without gastroesophageal reflux by high-resolution manometry (HRM). From June 2010 to July 2010, we enrolled 9 patients with GERD (GERD group) and 9 subjects without GERD (control group), prospectively. The manometry test was performed in a semi-recumbent position for 120 minutes following ingestion of a standardized, mixed liquid and solid meal. HRM was used to identify the frequency and duration of TLESR, esophageal shortening length from incomplete TLESR, upper esophageal sphincter (UES) response, and the related esophageal motor responses during TLESR. TLESR occurred in 33 in the GERD group and 34 in the control group after 120 minutes following food ingestion. Duration of TLESR and length of esophageal shortening did not differ between 2 groups. UES pressure increase during TLESR was mostly detected in patients with GERD, and UES relaxation was observed frequently in the control group during TLESR. TLESR-related motor responses terminating in TLESR were predominantly observed in the control group. Increased UES pressure was noted frequently in the GERD group, suggesting a mechanism for preventing harmful reflux, which may be composed mainly of fluid on the larynx or pharynx. However, patients with GERD lacked the related motor responses terminating in TLESR to promote esophageal emptying of refluxate.

Bariatric surgery is the only effective procedure that provides long-term sustained weight loss. Sleeve gastrectomy (SG) has emerged over the last few years to be an ideal bariatric procedure because it has several advantages compared to more complex bariatric procedures, including avoiding an intestinal bypass. However, several published follow-up studies report an increased rate of gastroesophageal reflux (GERD) after a SG. GERD is described as either de novo or as being caused by aggravation of preexisting symptoms. However, the literature on this topic is ambivalent despite the potentially increased rate of GERDs that may occur after this common bariatric procedure. This article reviews the mechanisms responsible for GERD in obese subjects as well as the results after a SG with respect to GERD. Future directions for clinical research are discussed along with the current surgical options for morbidly obese patients with GERD and undergoing bariatric surgery. PMID:26420961

The objective of the present study was to estimate the influence of gastroesophageal reflux disease (GERD) on the pH values in the pharynx and nose. It included 87 patients at the age varying from 18 to 81 years admitted to the Irkutsk-based Railway Clinical Hospital and allocated to four groups. Group 1 was comprised of 25 patients presenting with gastroesophageal reflux disease and chronic rhinosinusitis (CRS), group 2 consisted of 29 patients with CRS in the absence of GERD, group 3 included 22 patients with nasal septum deformations (NSD) and GERD, group 4 included 11 patients with NSD and motor rhinitis without GERD. The control group was formed from 10 volunteers. pH was measured by the contact method with the use ofEkokhim indicator paper. Gastroesophageal reflux disease was diagnosed following the recommendations of the Montreal consensus. It was shown that pH values in the pharynx of the patients with compromised nasal breathing of any origin in combination with GERD were lower than in the absence of GERD and in the healthy volunteers. The study groups did not differ in terms of pH values in the nasal cavity. It is concluded that pH values 4 or lower may serve as the criterion for pharyngo-laryngeal reflux (PLR) concomitant with HERD while pH 5 occurs more frequently in the patients with compromised nasal breathing of any etiology, regardless of the presence or absence of GERD.Disordered nasal breathing of any genesis in the patients presenting with gastroesophageal reflux disease was associated with the feeling of the lump in the throat, congestion of the respiratory tract and the nose, pain in the ears, cardialgia, and irregular heartbeat. It isrecommended to use pH measurements as a criterion for diagnostics of pharyngo-laryngeal reflux in the patients presenting with gastroesophageal reflux disease.

The function and structure of the gastro-esophageal junction (GEJ) determine its efficacy as a reflux barrier. This study presents a novel methodology for the quantitative assessment of GEJ and proximal gastric morphology from magnetic resonance (MR) imaging. Based on this data we propose a new conceptualization of the hypothesis that a flap valve mechanism contributes to reflux protection. 3D models of the GEJ and proximal stomach were reconstructed from MR images in 12 healthy volunteers during respiration and on eating a test meal to maximum satiation. A rotating plane analysis measured the gastro-esophageal insertion angle and span of contact. An ellipsoid fit provided quantitative assessment of gastric shape and orientation relative to a fixed anatomical reference point. Position of the esophageal insertion on the 'gastric ellipse' was noted. An ellipsoid-cylinder model was designed to analyze the relationships among parameters describing the GEJ morphology. The insertion angle became more acute on expiration, but did not change with meal ingestion. In contrast the span of contact did not vary with respiration, but increased with gastric filling. Changes in gastric morphology with distension further augmented the span of gastro-esophageal contact in almost 70% of the studies. Novel MR imaging and biophysical analysis of the GEJ and proximal stomach provide a quantitative description of structures contributing to the reflux barrier. Changes in these parameters during respiration and on eating support the hypothesis that structural components of a functional 'flap valve' like mechanism contribute to reflux protection. © 2012 Blackwell Publishing Ltd.

Gastroesophageal reflux disease (GERD) affects mental state and social activities. On the contrary, mental disorders may also play a crucial role in GERD symptoms. The purpose of the study was to analyze the data of Symptom Checklist 90-Revised (SCL-90-R) questionnaire from patients with persisting GERD and to explore the impact of psychological factors on them. The patients accepted SCL-90-R questionnaire survey, following endoscopy, high-resolution manometry (HRM), and ambulatory impedance-pH monitoring. Based on these results, we divided patients into different groups. The result of SCL-90-R was also compared with degree of acid reflux, symptoms, symptom duration, and gender. The data from 438 patients were analyzed. All patients were divided into reflux esophagitis (RE; 63, 14.38%); nonerosive gastroesophageal reflux disease (NERD; 106, 24.20%); functional heartburn (FH; 123, 28.08%), hypersensitive esophagus (HE; 67, 15.29%), diffuse esophageal spasm (DES; 5: 1.14%), hypertensive (10, 3.42%); weak peristalsis (14, 3.20%); achalasia (50, 11.42%). There were significant differences between different groups regarding depression (DEP), anxiety (ANX), paranoid ideation (PAR), and psychoticism (PSY). The patients with ≥2 years with GERD presented with increased scores in DEP, ANX, and PSY. Women had dramatically higher scores than men in each domain (p < 0.05). Data have shown that GERD patients exhibit differential levels of psychological symptoms. Long duration of GERD was related to typical plus atypical symptoms and females seem to be more prone to develop psychological disorders.

Gastroesophageal pathologies are common and multifactorial in patients with type 1 diabetes (T1DM). The evaluation with endoscopy and 24 h pH esophageal monitoring is expensive and not always available in all medical centers, especially in developing countries so more cost-effective algorithms for diagnosis are required. Clinical questionnaires are easy to apply but its utility for gastroesophageal reflux disease screening in patients with long standing T1DM must be analyzed. To evaluate the utility of the FSSG and Carlsson-Dent (CDQ) questionnaires to detect the frequency of gastroesophageal reflux disease in patients with T1DM. Analytic cross-sectional study, included 54 randomly selected patients from the T1DM clinic in our hospital. Before their routine evaluation, were asked to answer FSSG and CDQ questionnaires, classifying them as positive with a score >8 or >4, respectively. we associated and compared the clinical and biochemical characteristics between patients with or without gastroesophageal reflux detected through questionnaires. Median age was 29 years (22-35), 67% were female (median of 16 years from diagnosis). In 39% of the patients FSSG was positive, CDQ was positive in 28%. A total of 71% of patients were taking medications to treat non-specific gastric symptoms. The concordance between questionnaires was 65% ( p : <0.001). Those patients with tobacco consumption as well as those with poor glycemic control were more likely to score positive in either questionnaire. Patients T1DM had a high prevalence of gastroesophageal reflux disease. In those patients FSSG questionnaire detected a higher number of patients in comparison with CDQ.

Mucosal integrity can be assessed in patients with gastroesophageal reflux disease (GERD) by measuring intraluminal baseline impedance (BI). However, it is not clear whether BI is abnormal in patients with functional heartburn (FH), or can be used to distinguish them from patients with GERD. We compared differences in BI between patients with FH vs GERD. We performed a prospective study of 52 patients (16 men; mean age, 55 y; range, 23-78 y) seen at a tertiary university hospital from February 2009 through December 2012. Thirty-five patients had GERD (19 had nonerosive reflux disease [NERD], 16 had erosive reflux disease [ERD]) and 17 had FH. All patients discontinued proton pump inhibitor therapy and then underwent esophagogastroduodenoscopy and multichannel intraluminal impedance and pH monitoring. BI was assessed at 3, 5, 7, 9, 15, and 17 cm proximal to the lower esophageal sphincter in recumbent patients. Biopsy specimens were taken from 3 cm above the gastroesophageal junction; histology analysis was performed to identify and semiquantitatively score (scale, 0-3) dilated intercellular spaces. Baseline impedance in the distal esophagus was significantly lower in patients with NERD or erosive reflux disease (ERD) than FH (P = .0006). At a cut-off value of less than 2100 Ω, BI measurements identified patients with GERD with 78% sensitivity and 71% specificity, with positive and negative predictive values of 75%. Also in the proximal esophagus, reduced levels of BI levels were found only in patients with ERD. There were negative correlations between level of BI and acid exposure time (r = -0.45; P = .0008), number of acidic reflux episodes (r = -0.45; P = .001), and proximal extent (r = -0.40; P = .004). Biopsy specimens from patients with NERD or ERD had significant increases in dilation of intercellular spaces, compared with those from patients with FH; there was an inverse association between dilated intercellular spaces and BI in the distal esophagus

The confluence between the increased prevalence of gastro-esophageal reflux disease (GERD) and of obesity has generated great interest in the association between these two conditions. Several studies have addressed the potential relationship between GERD and obesity, but the exact mechanism by which obesity causes reflux disease still remains to be clearly defined. A commonly suggested pathogenetic pathway is the increased abdominal pressure which relaxes the lower esophageal sphincter, thus exposing the esophageal mucosal to gastric content. Apart from the mechanical pressure, visceral fat is metabolically active and it has been strongly associated with serum levels of adipo-cytokines including interleukin-6 and tumor necrosis factor α, which may play a role in GERD or consequent carcinogenesis. This summary is aimed to explore the potential mechanisms responsible for the association between GERD and obesity, and to better understand the possible role of weight loss as a therapeutic approach for GERD.

Histologic definition of gastro-esophageal reflux disease.

PubMed

Chandrasoma, Parakrama T

To review recent data supporting the development of new histology-based definitions of gastro-esophageal reflux disease (GERD). Three precisely definable columnar epithelial types--cardiac, oxyntocardiac and intestinal--may be interposed between esophageal squamous epithelium and gastric oxyntic (acid secreting) mucosa. This enables definition of a new histologic concept: the squamo-oxyntic gap. The squamo-oxyntic gap is zero or very small in autopsies performed on patients without evidence of GERD. The gap progressively increases in length with the severity of GERD, indicating that the squamo-oxyntic gap is a marker for chronic GERD. The distal part of the gap lines gastric-type rugal folds and, therefore, is distal to the present endoscopic definition of the gastro-esophageal junction. I contend that this distal gap segment (which has esophageal submucosal glands) is actually the dilated distal esophagus; this is the pathologic correlate of destruction of the abdominal segment of the lower esophageal sphincter. The dilated distal esophagus is mistaken for 'gastric cardia' by present endoscopic definitions. I believe that these data support the adoption of novel histologic definitions of GERD as follows: the presence of any squamo-oxyntic gap defines GERD; the length of the gap is a measure of severity of chronic GERD; and the presence of intestinal metaplasia in the gap defines Barrett esophagus and cancer risk.

Although the prevalence of gastroesophageal reflux disease (GERD) used to be lower in East Asia as compared to Western countries, it has recently been increasing, most likely due to the socioeconomic development in the East. The prevalence of both GERD and functional gastrointestinal disorders (FGIDs) ranges between 10% and 25% worldwide and there are distinct subgroups of patients with overlapping of GERD and FGIDs. However, the true prevalence of an overlap between GERD and FGIDs can be determined only when a formal pathophysiological evaluation has been performed. Nocturnal reflux symptoms have a significant impact on patients' sleep quality and quality of life. Although proton pump inhibitors (PPIs) can improve both reflux and sleep-related symptoms, the relationship between nocturnal reflux events and sleep disturbance is not fully understood. GERD plays an important role in the pathogenesis of lung fibrosis, and PPIs or fundoplication may decrease the likelihood of pulmonary exacerbation or even improve pulmonary function. Refractory reflux symptoms without esophagitis have become one of the most common presentations of GERD in gastroenterology clinics. There are several new medical therapies, and endoscopic as well as laparoscopic techniques that have been increasingly used in these patients. The selection of options should be tailored and individualized based on the pathophysiology of refractory GERD. © 2018 New York Academy of Sciences.

Medical therapy of gastroesophageal reflux disease (GERD) is based on the use of proton pump inhibitors (PPIs) as first choice treatment. Despite their effectiveness, about 20-30% of patients report an inadequate response and alternative drugs are required. Areas covered: This review provides an overview of current pharmacotherapy for treating GERD by showing the results of PPIs, reflux inhibitors, antidepressants and mucosa protective medications. Expert opinion: Medical therapy of GERD does not definitely cure the disease, because even PPIs are not able to change the key factors responsible for it. However, they remain the mainstay of medical treatment, allowing us to alleviate symptoms, heal esophagitis and prevent complications in the majority of cases. Nevertheless, many patients do not respond, because acid does not play any pathogenetic role. Prokinetics and reflux inhibitors have the potential to control motor abnormalities, but the results of clinical trials are inconsistent. Antidepressant drugs are effective in specific subgroups of NERD patients with visceral hypersensitivity, but larger, controlled clinical studies are necessary. Protective drugs or medical devices have been recently adopted to reinforce mucosal resistance and preliminary trials have confirmed their efficacy either combined with or as add-on medication to PPIs in refractory patients.

Oral manifestations in gastroesophageal reflux disease.

Many systemic diseases exert their influence on oral health. Among these, gastroesophageal reflux disease (GERD) is the most common. In this study, 100 patients who were previously diagnosed with GERD were examined following a 12-hour fast and evaluated in terms of the severity (grade) of the disease as well as any oral, dental, and/or salivary pH changes. Results found 11 patients with tooth erosion. These patients were older, and their average mean duration of GERD was longer in comparison to those without erosion. There was an inverse relationship between salivary pH and the GERD duration and grade of severity. As the GERD grade increased, the severity of tooth erosion increased. Patients with erosion also exhibited oral mucosal changes. Thus severe, long-term GERD was found to be potentially detrimental to oral soft tissues, dental structures, and salivary pH, whereas milder forms of the disease did not necessarily cause dental side effects.

To review the current literature on the role of antireflux surgery (ARS) for the treatment of extraesophageal manifestations of GERD. The extraesophageal manifestations of gastroesophageal reflux disease (GERD) include chronic cough, laryngopharyngeal reflux, and asthma. They are responsible for significant morbidity in affected patients and a high economic burden on healthcare resources. We recently published a larger review on the symptoms, diagnosis, medical, and surgical treatment of the extraesophageal manifestations of GERD. Through our investigation, we found that the role of ARS for respiratory symptoms was unclear. Hence, we resorted through the data of our previous meta-analysis to compile a comprehensive and focused review on the role of ARS for respiratory symptoms. Using the archive of our previous meta-analysis, we selected studies extracted from the MEDLINE, Cochran, PubMed, Google Scholar, and Embase databases pertaining to the surgical treatment of extraesophageal manifestations of reflux (cough laryngopharyngeal reflux, and asthma). We applied a similar reporting methodology as was used in our previous manuscript and then hand searched the bibliographies of included studies yielding a total of 27 articles for review. We graded the level of evidence and classified recommendations by size of treatment effect per the American Heart Association Task Force on Practice Guidelines. Observational data indicated that syndromes of chronic cough, laryngopharyngeal reflux and asthma might improve after antireflux surgery only in highly selected patients-likely those with non-acid reflux-while those patients with objective markers of asthma severity do not. Because of the varied methods of diagnosis and surgical technique, non-comparative observational data may be unreliable. Additionally, our search found no randomized controlled trials (RCTs) comparing antireflux surgery to medical therapy in the treatment of cough or laryngopharyngeal reflux. One RCT

Background/Aims The post-reflux swallow-induced peristaltic wave (PSPW) index and esophageal baseline impedance (BI) are novel impedance parameters used to evaluate esophageal chemical clearance and mucosal integrity. However, their relationship with reflux symptoms is not known. We aim to evaluate the correlations of PSPW index and esophageal BI with gastroesophageal reflux disease (GERD) symptoms. Methods We performed a retrospective review of multichannel intraluminal impedance and pH (MII-pH) tracings in patients with suspected GERD. Reflux symptoms were also analyzed from checklists using ordinal scales. The PSPW index and esophageal BIs in 6 spots (z1–z6) were measured. Bivariate (Spearman) correlation was used to analyze the relationship between the PSPW index or esophageal BI, and the degree of GERD symptoms measured. Results The MII-pH records of 143 patients were analyzed. The PSPW index was significantly lower in patients who had heartburn and negatively correlated with the degree of heartburn (r = −0.186, P < 0.05). On the contrary, the PSPW index was not significantly correlated with the degree of dysphagia (r = −0.013, P = 0.874). Distal esophageal BI was not significantly correlated with heartburn, but negatively correlated with the degree of dysphagia (z3: r = −0.328, z4: r = −0.361, z5: r = −0.316, z6: r = −0.273; P < 0.05). Conclusions These findings suggest that delayed chemical clearance of the esophagus may induce heartburn, but that it is not related to dysphagia. However, a lack of esophageal mucosal integrity may be related to dysphagia. PMID:28044052

Objective Sleeve gastrectomy is the fastest growing surgical procedure to treat obesity in the world but it may cause or worsen gastroesophageal reflux disease. This article originally aimed to describe the addition of anti-reflux procedures (removal of periesophageal fats pads, hiatoplasty, a small plication and fixation of the gastric remnant in position) to the usual sleeve gastrectomy and to report early and late results. Methods Eighty-eight obese patients that also presented symptoms of gastroesophageal reflux disease were submitted to sleeve gastrectomy with anti-reflux procedures. Fifty of them were also submitted to a transit bipartition. The weight loss of these patients was compared to consecutive 360 patients previously submitted to the usual sleeve gastrectomy and to 1,140 submitted to sleeve gastrectomy + transit bipartition. Gastroesophageal reflux disease symptoms were specifically inquired in all anti-reflux sleeve gastrectomy patients and compared to the results of the same questionnaire applied to 50 sleeve gastrectomy patients and 60 sleeve gastrectomy + transit bipartition patients that also presented preoperative symptoms of gastroesophageal reflux disease. Results In terms of weight loss, excess of body mass index loss percentage after anti-reflux sleeve gastrectomy is not inferior to the usual sleeve gastrectomy and anti-reflux sleeve gastrectomy + transit bipartition is not inferior to sleeve gastrectomy + transit bipartition. Anti-reflux sleeve gastrectomy did not add morbidity but significantly diminished gastroesophageal reflux disease symptoms and the use of proton pump inhibitors to treat this condition. Conclusion The addition of anti-reflux procedures, such as hiatoplasty and cardioplication, to the usual sleeve gastrectomy did not add morbidity neither worsened the weight loss but significantly reduced the occurrence of gastroesophageal reflux disease symptoms as well as the use of proton pump inhibitors.

Purpose of Study: The purpose is to evaluate the findings and utility of esophageal transit scintigraphy (ETS) and gastroesophageal reflux scintigraphy (GES) in patients presenting with upper respiratory tract (URT) symptoms suspected to be due to gastroesophageal reflux (GER) disease. Materials and Methods: Thirty patients aged between 19 and 60 years underwent nasopharyngolaryngoscopy (NPL), ETS, and GES. Correlation between GER, esophageal motility, and NPL was evaluated. Inclusion criteria include patients with recurrent URT symptoms such as chronic dry cough/hoarseness of voice and itching/foreign body sensation in throat. Those with typical gastrointestinal (GI) symptoms of GER, URT symptoms relieved by antibiotics, surgical intervention in abdomen, cardiac/hepatobiliary diseases, etc. were excluded from the study. Results: Significant correlation was found between GER and NPL in 28/30 patients. More the grade of reflux, more severe was the NPL findings. Two patients with Grade II reflux had normal NPL suggesting structural inflammatory changes due to acidic pH of refluxate which have not yet manifested or symptoms could be due to nonacid refluxate. Incidence of esophageal motility disorder was statistically significant in patients with GER disease (GERD). Patients who had symptoms, but no demonstrable GER showed delayed ET in supine position suggesting the presence of esophageal motility disorder even before GERD. Conclusion: GES demonstrated GER in patients presenting with URT symptoms without typical GI symptoms. ETS showed coexistence of esophageal motility disorder in most patients presenting with URT symptoms even without an associated reflux disease. We hypothesize that primary abnormal esophageal motility leads to delayed esophageal clearance and consequently to URT symptoms. Addition of ETS to GES is easily feasible with no significant additional cost, time, or radiation burden. PMID:29430111

Obesity increases the risk of gastroesophageal reflux disease (GERD). The majority of the reflux attacks occur postprandially. The influence of the speed of food intake on gastroesophageal reflux events is unclear in obese patients. To determine the influence of the speed of food intake on intraesophageal reflux events in obese patients with and without GERD. A total of 26 obese female patients were recruited. The patients underwent esophageal manometry to evaluate the upper limit of the lower esophageal sphincter and subsequently placement of a Multichannel intraluminal impedance-pH (MII-pH) catheter. All patients were asked to eat the same standard meal (double cheeseburger, 1 banana, 100 g yogurt and 200 mL water; total energy value, 744 kcal; 37.6% carbohydrates, 21.2% proteins and 41.2% lipids) within 5 or 30 minutes under observation in a random order on two consecutive days. All reflux episodes over a 3-hour postprandial period were manually analyzed and compared. The mean age was 46 ± 12 (18-66) years. The mean body mass index (BMI) was 39.9 ± 8.4 kg/m2. There was no difference between the fast- and slow-eating group in the number of refluxes within the 3-postprandial hours. The patients were divided into 2 groups according to the 24-hour MII-pH monitoring results, that is, 16 subjects with normal MII-pH monitoring and 10 patients with pathologic MII-pH monitoring. There was no effect of the speed of food intake in either the patients with or without GERD. In contrast to the general belief, this study suggested that the speed of food intake does not influence the number of refluxes in obese female patients with or without GERD. © 2016 International Society for Diseases of the Esophagus.

Proton pump inhibitor resistance, the real challenge in gastro-esophageal reflux disease.

Gastro-esophageal reflux disease (GERD) is one of the most prevalent chronic diseases. Although proton pump inhibitors (PPIs) represent the mainstay of treatment both for healing erosive esophagitis and for symptom relief, several studies have shown that up to 40% of GERD patients reported either partial or complete lack of response of their symptoms to a standard PPI dose once daily. Several mechanisms have been proposed as involved in PPIs resistance, including ineffective control of gastric acid secretion, esophageal hypersensitivity, ultrastructural and functional changes in the esophageal epithelium. The diagnostic evaluation of a refractory GERD patients should include an accurate clinical evaluation, upper endoscopy, esophageal manometry and ambulatory pH-impedance monitoring, which allows to discriminate non-erosive reflux disease patients from those presenting esophageal hypersensitivity or functional heartburn. Treatment has been primarily based on doubling the PPI dose or switching to another PPI. Patients with proven disease, not responding to PPI twice daily, are eligible for anti-reflux surgery.

In a previous issue published in Gut and Liver, we found that erosive changes in the esophagogastroduodenal mucosa were strongly correlated with increased levels of volatile sulfur-containing compounds (VSC), suggesting that halitosis could be a symptom reflecting the erosive status of the upper gut mucosa. Together with other studies showing a possible association between halitosis and gastroesophageal reflux disease (GERD), under the premise that halitosis could be one of extraesophageal manifestations of erosive GERD (ERD), we investigated the significance of Halimeter ppb levels on ERD compared to non-erosive gastroesophageal reflux disease (NERD). Subjects were assigned to the NERD group if there was no evidence of esophageal erosive changes on endoscopy, despite reflux symptoms, and to the ERD group if they had GERD A, B, C, or D (according to the Los Angeles classification). The VSC levels were measured in all patients with either a Halimeter (before endoscopy) or by gas chromatography of the gastric juices aspirated during endoscopy. The VSC level differed significantly between the NERD and ERD groups (p<0.0001), suggesting that this can be used to discriminate between NERD and ERD. However, the VSC level did not differ significantly with the severity of GERD. Even though hiatal hernia and a body mass index of >24 kg/m(2) was significantly associated with ERD, there was no correlation with Halimeter ppb levels. Minimal-change lesions exhibited the highest VSC levels, signifying that minimal change lesions can be classified as ERD based on our finding that halimeter ppb levels were descrimitive of erosive change. Erosive changes in the esophageal mucosa were strongly associated with VSC levels, supporting the hypothesis that halitosis can be a potential biomarker for the discrimination between ERD and NERD, reflecting the presence of erosive change in the lower esophagogastric junction.

Background There exists a complex interplay between asthma and gastroesophageal reflux disease. Both these diseases are known to aggravate each other and amelioration of one is necessary for the control of the other. There is a paucity of studies in Indian population on this subject. Aim To evaluate the clinical features and the endoscopic findings of the upper gastrointestinal tract in patients with bronchial asthma. Materials and Methods Study was conducted at KMC group of hospitals, Mangalore in the Department of chest medicine in association with Department of gastroenterology. Subjects included 50 cases of bronchial asthma and controls were 58 non asthmatic patients with allergic rhinitis and chronic urticaria. All patients were queried about presence or absence of symptoms of upper gastro intestinal tract disorders by gastro oesophageal reflux disease (GERD) questionnaire and all the included patients underwent upper gastro intestinal endoscopy. Results The study showed that symptoms of gastroesophageal reflux were significantly more in asthmatics (52%) as compared to the controls (28%). The common presenting features of gastroesophageal reflux in asthmatics were heartburn (40%) retrosternal pain (24%), nocturnal cough (18%), dyspepsia (16%) and regurgitation (14%) and the above symptoms were significantly more common in asthmatics as compared to controls. Gastroesophageal reflux disease was found to be significantly more common in the asthmatics (58%) as compared to the control group where it was present in 32.75% of the subjects. Clinical or endoscopic evidence of any upper gastrointestinal disorder was found in 68% of the asthmatics as compared to 37.93% of the controls. This difference was found to be statistically significant. Conclusion The study showed that gastroesophageal reflux disease was significantly more in asthmatics as compared to the controls. Upper gastrointestinal symptoms were more common in asthmatics as against controls. Clinical or

Refractory gastro-esophageal reflux disease (GERD), defined as persistent symptoms despite proton pump inhibitor (PPI) therapy, is an increasingly prevalent condition and is becoming a major challenge for the clinician. Since non-acidic reflux may be associated with symptoms persisting during PPI treatment, the lower esophageal sphincter (LES), the most important barrier protecting against reflux, has become an important target for the treatment of (refractory) GERD. Preclinical research has identified several receptors that are involved in the control of transient lower esophageal sphincter relaxations (TLESRs), the predominant mechanism of both acid and non-acidic reflux events, and several drugs have now been tested in humans. The GABA(B) agonist baclofen has demonstrated to effectively reduce the rate of TLESRs and the amount of reflux in both GERD patients and healthy volunteers. Nevertheless, the occurrence of central side effects limits its clinical use for the treatment of GERD. Several analogues are being developed to overcome this limitation and have shown promising results. Additionally, metabotropic glutamate receptor 5 (mGluR5) receptor antagonists have shown to reduce both acid and non-acidic reflux in GERD patients and several molecules are currently being evaluated. Although CB(1) antagonists have been shown to reduce TLESRs, they are also associated with central side effects, limiting their clinical applicability. Despite the identification of several potentially interesting drugs, the main challenge for the future remains the reduction of central side effects. Moreover, future studies will need to demonstrate the efficacy of these treatments in patients with refractory GERD.

Gastroesophageal reflux disease-related and functional heartburn: pathophysiology and treatment.

Patients who continue to experience heartburn symptoms despite adequate-dose proton pump inhibitor therapy have unmet clinical needs. In this review, we focus on the most recent findings related to the mechanism of heartburn symptom generation, and on the treatment of gastroesophageal reflux disease-related and functional heartburn. The immunological mechanism in the esophageal mucosa has been addressed as a potential mechanism of the onset of esophageal mucosa damage and the generation of heartburn symptoms. Peripheral or central hypersensitivity in viscera is a potentially unifying pathophysiological concept in functional heartburn. Vonoprazan, a novel and potent first-in-class potassium-competitive acid blocker, is expected to prove useful in the treatment of reflux disease. New findings in the mechanisms of heartburn symptom generation are emerging, including the immunological mediation of esophageal mucosal damage and the development of visceral hypersensitivity in functional heartburn. In the future, we anticipate the emergence of new and specific therapeutic options based on these mechanisms, with less dependence on acid-suppressing agents.

A Modern Magnetic Implant for Gastroesophageal Reflux Disease.

Ganz, Robert A

2017-09-01

A magnetic implant for the treatment of gastroesophageal reflux disease (GERD) was Food and Drug Administration-approved in 2012 and has been extensively evaluated. The device is a ring of magnets that are placed around the gastroesophageal junction, augmenting the native lower esophageal sphincter and preventing reflux yet preserving lower esophageal sphincter physiologic function and allowing belching and vomiting. Magnetic force is advantageous, being permanent and precise, and forces between magnets decrease with esophageal displacement. Multiple patient cohorts have been studied using the magnetic device, and trials establish consistent, long-term improvement in pH data, GERD symptom scores, and proton-pump inhibitor use. A 5-year Food and Drug Administration trial demonstrated that most patients achieved normal pH scores, 85% stopped proton-pump inhibitors, and GERD health-related quality of life symptom scores improved from 27 to 4 at 5 years. Seven studies have compared magnetic augmentation with laparoscopic Nissen fundoplication and demonstrated that the magnetic device achieved comparable efficacy with regard to proton-pump inhibitor cessation, GERD symptom score improvement, and heartburn and regurgitation scores. However, to date there have been no randomized, controlled trials comparing the 2 techniques, and the study cohorts are not necessarily comparable regarding hiatal hernia size, severity of reflux, body mass index scores, or esophagitis scores. Dysphagia incidence was similar in both groups. Reoperation rates and safety profiles were also comparable, but the magnetic device demonstrated significant beneficial differences in allowing belching and vomiting. The magnetic device is safe, with the main adverse event being dysphagia with an approximate 3%-5% chronic incidence. Device removals in clinical trials have been between 0% and 7% and were uneventful. There have been no erosions, perforations, or infections in FDA clinical trials

Purpose Gastro-esophageal reflux (GER), particularly non-acid reflux, is common in infants and is a known cause of chronic respiratory symptoms in infancy. Recent guidelines recommended empirical acid suppression therapy and the head-up position in patients with suspected GER. However, the efficacy of the upright position in relieving GER and reflux-related respiratory symptoms in infants is unclear. We conducted this study to investigate the efficacy of the upright position on GER and reflux-related respiratory symptoms in infants with chronic respiratory symptoms. Methods Thirty-two infants (21 male; median age, 5 months; range, 0 to 19 months) with unexplained chronic respiratory symptoms underwent multi-channel intraluminal esophageal impedance and pH monitoring. We retrospectively compared the frequencies of GER and reflux-related symptoms according to body position. Results A mean of 3.30 episodes of reflux per hour was detected. Overall, refluxes were more frequent during the postprandial period than the emptying period (3.77 vs. 2.79 episodes/hour, respectively; P=0.01). Although there was no significant difference in the total refluxes per hour between the upright and recumbent positions (6.12 vs. 3.77 episodes, P=0.10), reflux-related respiratory symptoms per reflux were significantly fewer in infants kept in an upright position than in a recumbent position during the postprandial period (3.07% vs. 14.75%, P=0.016). Non-acid reflux was the predominant type of reflux in infants, regardless of body position or meal time. Conclusions The upright position may reduce reflux-related respiratory symptoms, rather than reflux frequency. Thus, it may be a useful non-pharmacological treatment for infantile GER disease resistant to acid suppressants. PMID:22211166

Epidemiology of Gastroesophageal Reflux Disease in Asia: A Systematic Review

PubMed Central

2011-01-01

Ethnic and geographical differences are important factors in studying disease frequencies, because they may highlight the environmental or genetic influences in the etiology. We retrieved the studies which have been published regarding the epidemiologic features of gastroesophageal reflux disease (GERD) in Asia, based on the definitions of GERD, study settings, publication years and geographical regions. From the population-based studies, the prevalence of symptom-based GERD in Eastern Asia was found to be 2.5%-4.8% before 2005 and 5.2%-8.5% from 2005 to 2010. In Southeast and Western Asia, it was 6.3%-18.3% after 2005, which was much higher than those in Eastern Asia. There were robust epidemiologic data of endoscopic reflux esophagitis in medical check-up participants. The prevalence of endoscopic reflux esophagitis in Eastern Asia increased from 3.4%-5.0% before 2000, to 4.3%-15.7% after 2005. Although there were only limited studies, the prevalence of extra-esophageal syndromes in Asia was higher in GERD group than in controls. The prevalence of Barrett's esophagus was 0.06%-0.84% in the health check-up participants, whereas it was 0.31%-2.00% in the referral hospital settings. In summary, the prevalence of symptom-based GERD and endoscopic reflux esophagitis has increased in Asian countries. However, the prevalence of Barrett's esophagus in Asia has not changed and also still rare. PMID:21369488

Ethnic differences in gastroesophageal reflux disease (GERD) and its complications as well as racial variations in the prevalence of Helicobacter pylori infection are well documented. Nevertheless, the association between reflux disease, H. pylori, and race has not been adequately explored. We estimated the strength of the association between H. pylori, ethnicity, and the gastroesophageal reflux disease (GERD) spectrum, including Barrett's esophagus, in Asian patients presenting for endoscopy in a tertiary referral center. Prospectively, we studied 188 consecutive patients with GERD, short- and long-segment Barrett's esophagus, and controls. All patients underwent gastroscopy with gastric biopsies to assess H. pylori, gastritis, and atrophy. CagA status and H. pylori infection were determined by immunoblot assay. The overall prevalence of H. pylori infection was 52.1% (of which 77.6% were cagA(+)) and was lowest in the long-segment Barrett's esophagus group (36.7%) (p = .048). When Barrett's esophagus was present, the length of abnormality was 44.8% shorter in the presence of H. pylori (p = .015). Indians had the highest prevalence of H. pylori (75%) and Malays the lowest (19.6%) (p < .001). In Indians, increased prevalence of H. pylori and cagA-positive strains was associated with reduced severity of GERD (p < .004 and p < .001, respectively), a trend not apparent in the other races. Corpus atrophy, which was almost exclusively associated with H. pylori, was highest in Indians as compared to the other races (p = .013). Presence of H. pylori was associated with a reduced severity of GERD spectrum disease in Asians, especially Indians. H. pylori infection may protect against complicated reflux disease via induction of corpus atrophy.

The involvement of delayed gastric emptying (GE) in the pathophysiology of gastro-esophageal reflux disease (GERD) remains debated and has been to date only assessed using esophageal pH-metry that only detects acidic reflux. We therefore investigated whether delay in GE could impact on liquid, mixed, and gas reflux detected using combined esophageal pH-impedance recording. Thirty consecutive patients were explored with GE and esophageal pH-impedance measurement in the workup of typical symptoms of GERD. Gastric emptying was assessed using the (13) C-octanoic acid breath test and an ambulatory esophageal pH-impedance recording was performed off proton pump inhibitors (PPIs) for 24 h. Gastric emptying was normal in 17 patients and delayed in 13 patients. Delay in GE increased the daily number of liquid/mixed reflux events detected by combined esophageal pH-impedance monitoring, but had no effect of esophageal acid exposure or gas reflux. This translated in increased number of postprandial reflux events, with a longer bolus clearance time and increased esophageal proximal extension. In patient with delayed GE, symptomatic reflux had a higher proximal extension and a longer bolus clearance time compared to symptomatic reflux events from patients with normal GE. Delay in GE increases daily and postprandial liquid/mixed reflux events. Reflux characteristics differently trigger symptoms in patients with normal and delayed GE, and may impact on the therapeutic strategy. © 2013 John Wiley & Sons Ltd.

To investigate the utility of scintigraphic studies in predicting response to laparoscopic fundoplication (LF) for chronic laryngopharyngeal reflux symptoms. Patients with upper aero-digestive symptoms that remained undiagnosed after a period of 2 mo were studied with conventional pH and manometric studies. Patients mainly complained of cough, sore throat, dysphonia and globus. These patients were imaged after ingestion of 99m-technetium diethylene triamine pentaacetic acid. Studies were quantified with time activity curves over the pharynx, upper and lower oesophagus and background. Late studies of the lungs were obtained for aspiration. Patients underwent LF with post-operative review at 3 mo after surgery. Thirty four patients (20 F, 14 M) with an average age of 57 years and average duration of symptoms of 4.8 years were studied. Twenty four hour pH and manometry studies were abnormal in all patients. On scintigraphy, 27/34 patients demonstrated pharyngeal contamination and a rising or flat pharyngeal curve. Lung aspiration was evident in 50% of patients. There was evidence of pulmonary aspiration in 17 of 34 patients in the delayed study (50%). Pharyngeal contamination was found in 27 patients. All patients with aspiration showed pharyngeal contamination. In the 17 patients with aspiration, graphical time activity curve showed rising activity in the pharynx in 9 patients and a flat curve in 8 patients. In those 17 patients without pulmonary aspiration, 29% (5 patients) had either a rising or flat pharyngeal graph. A rising or flat curve predicted aspiration with a positive predictive value of 77% and a negative predictive value of 100%. Over 90% of patients reported a satisfactory symptomatic response to LF with an acceptable side-effect profile. Scintigraphic reflux studies offer a good screening tool for pharyngeal contamination and aspiration in patients with gastroesophageal reflux disease.

The objective of the present study was the determination of the incidence of gastroesophageal reflux disease and the evaluation of its possible influence on the development and duration of chronic exudative otitis media in the children during the first year of life. A total of 141 infants at the age of 3 months presenting with exudative otitis media refractory to the conservative treatment throughout the first 1-1.5 months of life were available for the examination. The effectiveness of the anti-reflux therapy was estimated based on the middle ear condition (the presence or absence of exudate) within 3 and 6 months after the initiation of the treatment. The signs of aspiration of gastric chimus and gastroesophageal reflux disease were documented in 92% of the cases. The anti-reflux treatment during 3 months resulted in the disappearance of the manifestations of exudative otitis media in 43% of the patients. The further prolongation of such therapy up to 6 months allowed to normalize the state of the middle ear in 69% of the children although the remaining 40% failed to respond. It is concluded that the treatment of the children presenting with exudative otitis media during first year of life should be performed taking into consideration the possible involvement of gastroesophageal reflux disease in pathogenesis of this pathological condition.

Differences in lower esophageal sphincter (LES) and peristaltic function and in transient LES relaxations (TLESR) have been described in patients with gastro-esophageal reflux disease (GERD). However, some of these differences may be the result of chronic GERD rather than being an underlying contributory factor. Twins discordant for GERD symptoms, i.e., only one twin had GERD symptoms, underwent standard LES and esophageal body manometry, and then using a sleeve sensor prolonged LES and pH monitoring, 30 min before and 60 min after a 250 mL 1200 kcal lipid meal. Eight monozygotic and 24 dizygotic female twins were studied. Although there was no difference in preprandial LES pressure (symptomatic 13.2 ± 7.1 mmHg vs asymptomatic 15.1 ± 6.2 mmHg, P = 0.4), LES pressure fell further postprandially in symptomatic twins (LES pressure area under the curve 465 ± 126 vs 331 ± 141 mmHg h, P < 0.01). 12/37 (32%) of acid reflux episodes in symptomatic twins occurred due to low LES pressure or deep inspiration/strain and 0/17 in asymptomatic twins (P = 0.01). There was no difference between symptomatic and asymptomatic twins in: peristaltic amplitude, ineffective esophageal body motility, hiatus hernia prevalence, or LES length. There was also no difference in TLESR frequency preprandially (symptomatic median 1(range 0-2) vs asymptomatic 0(0-2), P = 0.08) or postprandially (2.5(1-8) vs 3(1-6), P = 0.81). Twins with GERD symptoms had lower postprandial LES pressure and given the close genetic link between the twins, it is possible that such differences are caused by GERD. Acid reflux episodes associated with a hypotensive LES were seen in symptomatic, but not in asymptomatic twins. © 2013 John Wiley & Sons Ltd.

The effect of laparoscopic sleeve gastrectomy (SG) on gastroesophageal reflux disease (GERD) has been a controversial issue. There have been limited studies on this aspect and most of the published studies are retrospective. Therefore, a prospective study was designed to objectively assess the problem. The objective of this study was to assess the impact of SG on symptoms of gastroesophageal reflux using questionnaire, endoscopy, and radionuclide scintigraphy. Thirty-two patients undergoing laparoscopic sleeve gastrectomy were assessed for gastroesophageal reflux using Carlsson Dent Questionnaire and GERD questionnaire before and after surgery at three monthly intervals. They were also subjected to upper GI endoscopy (UGIE) and radionuclide scintigraphy both pre- and postoperatively. Mean preoperative weight and body mass index were 126.5 kg and 47.8 kg/m2, respectively. Mean percent excess weight loss at 12 months was 64.3 ± 18.4. Both the Carlsson Dent Score (CDS) and Severity Score (SS) exhibited a decline from 2.88 to 1.63 (p<0.05) and 2.28 to 1.06 (p<0.05), respectively after 12 months. Radionuclide scintigraphy revealed a significant rise of GERD from 6.25% to 78.1% in the postoperative period (p<0.001). UGIE showed a rise in incidence of esophagitis from 18.8% to 25%; however, there was improvement in all patients except one in terms of reduction of severity of esophagitis. Presence of GERD may not be considered as a contra-indication for sleeve gastrectomy. There is improvement of GERD as assessed by symptom questionnaires, as well as improvement in grade of esophagitis. The new onset GERD detected on scintigraphy may not be pathologic as there is a decrease in total acid production postsurgery; however, it still remains an important issue and needs long-term follow-up.

Gastroesophageal reflux disease and esophageal dysmotility are prevalent in patients with advanced lung disease and are associated with graft dysfunction following lung transplantation. As a result, many transplant centers perform esophageal function testing as part of the wait-listing process but guidelines for testing in this population are lacking. The aim of this study is to describe whether symptoms of gastroesophageal reflux correlate with abnormal results on pH-metry and high-resolution manometry and can be used to identify those who require testing. We performed a retrospective cohort study of 226 lung transplant candidates referred for high-resolution manometry and pH-metry over a 12-month period in 2015. Demographic data, results of a standard symptom questionnaire and details of esophageal function testing were obtained. Associations between the presence of symptoms and test results were analyzed using Fisher's exact tests and multivariable logistic regression. The most common lung disease diagnosis was interstitial lung disease (N = 131, 58%). Abnormal pH-metry was seen in 116 (51%) patients and the presence of symptoms was significantly associated with an abnormal study (p < 0.01). Dysmotility was found in 98 (43%) patients, with major peristaltic or esophageal outflow disorders in 45 (20%) patients. Symptoms were not correlated with findings on esophageal high-resolution manometry. Fifteen of 25 (60%) asymptomatic patients had an abnormal manometry or pH-metry. These results demonstrate that in patients with advanced lung disease, symptoms of gastroesophageal reflux increase the likelihood of elevated acid exposure on pH-metry but were not associated with dysmotility. Given the proportion of asymptomatic patients with abnormal studies and associated post-transplant risks, a practice of universal high-resolution manometry and pH-metry testing in this population is justifiable.

Abstract Background: Laparoscopic Nissen fundoplication (LNF) has been the gold standard for the surgical management of Gastro-esophageal reflux disease (GERD). Laparoscopic anterior 180° fundoplication (180° LAF) is reported to reduce the incidence of postoperative complications while obtaining similar control of reflux. The present meta-analysis was conducted to confirm the value of the 2 techniques. Methods: PubMed, Medline, Embase, Cochrane Library, Springerlink, and China National Knowledge Infrastructure Platform databases were searched for randomized controlled trials (RCTs) comparing LNF and 180° LAF. Data regarding the benefits and adverse results of 2 techniques were extracted and compared using a meta-analysis. Results: Six eligible RCTs comparing LNF (n = 266) and 180° LAF (n = 265) were identified. There were no significant differences between LNF and 180° LAF with regard to operating time, perioperative complications, length of hospital stay, patient satisfaction, willingness to undergo surgery again, quality of life, postoperative heartburn, proton pump inhibitor (PPI) use, postoperative DeMeester scores, postoperative lower esophageal sphincter (LES) pressure, postoperative gas-bloating, unable to belch, diarrhea, or overall reoperation. LNF was associated with a higher prevalence of postoperative dysphagia compared with 180° LAF, while 180° LAF was followed by more reoperation for recurrent reflux symptoms. Conclusion: LNF and 180° LAF are equally effective in controlling reflux symptoms and obtain a comparable prevalence of patient satisfaction. 180° LAF can reduce the incidence of postoperative dysphagia while this is offset by a higher risk of reoperation for recurrent symptoms. The risk of recurrent symptoms should need to be balanced against the risk of dysphagia when surgeons choose surgical procedures for each individual with GERD. PMID:28906412

Belching is a common symptom of gastroesophageal reflux disease. If the symptoms are not relieved after anti-reflux treatment, another etiology should be considered. Here, we report a case of a 43-year-old man who presented with belching, regurgitation, chest tightness and dyspnea for 18 mo, which became gradually more severe. Gastroscopic examination suggested superficial gastritis. Twenty-four-hour esophageal pH monitoring showed that the Demeester score was 11.4, in the normal range. High-resolution manometry showed that integrated relaxation pressure and intrabolus pressure were higher than normal (20 mmHg and 22.4 mmHg, respectively), indicating gastroesophageal junction outflow tract obstruction. Pulmonary function test showed severe obstructive ventilation dysfunction [forced expiratory volume in 1 second (FEV1)/forced vital capacity 32%, FEV1 was 1.21 L, occupying 35% predicted value after salbuterol inhalation], and positive bronchial dilation test (∆FEV1 260 mL, ∆FEV1% 27%). Skin prick test showed Dermatophagoides farinae (++), house dust mite (++++), and shrimp protein (++). Fractional exhaled nitric oxide measurement was 76 ppb. All the symptoms were alleviated completely and pulmonary function increased after combination therapy with corticosteroids and long-acting β2-agonist. Bronchial asthma was eventually diagnosed by laboratory tests and the effect of anti-asthmatic treatment, therefore, physicians, especially the Gastrointestinal physicians, should pay attention to the belching symptoms of asthma.

With wide application of antireflux surgery, reoperations for failed fundoplications are increasingly seen. This study was undertaken to document outcomes after reoperative fundoplications. Sixty-four patients, 26 men and 38 women, of average age 55 years+/-15.6 (SD), underwent reoperative antireflux surgery between 1992 and 2003. Fundoplication prior to reoperation had been undertaken via celiotomy in 27 and laparoscopically in 37. Both before and after reoperative antireflux surgery, patients scored their reflux and dysphagia on a Likert Scale (0 = none, 10 = continuous). Reoperation was undertaken because of dysphagia in 16 per cent, recurrent reflux in 52 per cent (median DeMeester Score 52), or both in 27 per cent. Failure leading to reoperation was due to hiatal failure in 28 per cent, wrap failure in 19 per cent, both in 33 per cent, and slipped Nissen fundoplication in 20 per cent. Laparoscopic reoperations were completed in 49 of 54 patients (91%); 15 had reoperations undertaken via celiotomy. Eighty-eight per cent of reoperations were Nissen fundoplications. With reoperation, Dysphagia Scores improved from 9.5+/-0.7 to 2.6+/-2.8, and Reflux Scores improved from 9.1+/-1.4 to 1.8+/-2.7. Seventy-nine per cent of patients with reflux prior to reoperation, 100 per cent with dysphagia, and 74 per cent with both noted excellent or good outcomes after reoperation. We conclude that failure after fundoplication occurs. Reoperations reduce the severity of dysphagia and reflux, thus salvaging excellent and good outcomes in most. Laparoscopic reoperations are generally possible. Reoperative fundoplications are effective treatment for dysphagia and recurrent gastroesophageal reflux, and their application is encouraged.

Pathophysiology of gastro-esophageal reflux disease: a role for mucosa integrity?

PubMed

Farré, R

2013-10-01

Gastro-esophageal reflux disease (GERD) is very prevalent and has a high burden on health security system costs. Nevertheless, pathophysiology is complex and not well-understood. Several mechanisms have been proposed: decreased salivation, impaired esophageal clearance, decreased lower esophageal sphincter pressure resting tone, presence of hiatal hernia, increased number of transient lower esophageal sphincter relaxations (TLESRs), increased acid, and pepsin secretion, pyloric incompetence provoking duodeno-gastro-esophageal reflux of bile acids and trypsin. Independent of the relevance of each mechanism, the ultimate phenomenon is that mucosal epithelium is exposed for a longer time to agents as acid and pepsin or is in contact to luminal agents not commonly present in gastric refluxate as trypsin or bile acids. This leads to a visible damage of the epithelium (erosive esophagitis -EE) or impairing mucosal integrity without any sign of macroscopic alteration as occurs in non-erosive reflux disease (NERD). Luminal factors are not the only responsible for such impairment; more recent data indicate that endogenous factors may also play a role. This review will update the most recent findings on the putative pathophysiological mechanisms and specially will focus on the role of esophageal mucosal integrity in GERD. Methodologies used for the evaluation of mucosal integrity, its relevance in EE and NERD, its involvement in symptoms perception and the effect of luminal and endogenous factors will be discussed. © 2013 John Wiley & Sons Ltd.

To evaluate the clinical effect of preventing gastroesophageal reflux (GER) and aspiration in neonates delivered by elective cesarean section with hand immediately after birth. On the basis of the principles for drowning resuscitation and evaluation of the principal factors causing GER and aspiration, the author adopted immediate manual management to promote emptying of gastroesophageal and airway contents in 496 newborns delivered by elective cesarean section. No GER and aspiration occurred in the babies receiving the management, and no complication was recorded. As an early preventive measure, manual management is effective in clearing gastroesophageal and airway contents against GER and aspiration, and Apgar scoring can be readily conducted.

Mucosal Impedance: a New Approach to Diagnosing Gastroesophageal Reflux Disease and Eosinophilic Esophagitis.

PubMed

Barrett, Caroline; Choksi, Yash; Vaezi, Michael F

2018-06-09

In this review, we discuss current diagnostic testing modalities for both gastroesophageal reflux disease (GERD) and eosinophilic esophagitis (EoE) and then introduce mucosal impedance (MI), a novel technology that measures epithelial integrity in real time during endoscopy. We describe the advantages and disadvantages of MI as compared with traditional diagnostic testing. We review studies that demonstrate that GERD and EoE have distinct MI patterns, and that physicians can accurately diagnose and distinguish the two during endoscopy with minimal time added to the procedure. We also review studies showing that MI has the capability to assess treatment response in both GERD and EoE and that it can be used to diagnose GERD in patients with extraesophageal reflux symptoms. Mucosal impedance testing is a major advancement in the diagnosis of GERD and EoE. Future studies are planned to assess whether MI can be used as a treatment endpoint in EoE and whether it can be used to predict response to anti-reflux surgery.

Few studies have evaluated the impact of gastroesophageal reflux disease symptoms on work productivity and no French data are available. To compare the impact of typical symptoms of nocturnal vs diurnal gastroesophageal reflux disease on work productivity and daily activities. A French prospective, multicenter, observational study was performed in primary care setting. Patient characteristics, symptomatology and treatment were reported. Work productivity loss was assessed using the work productivity and activity impairment questionnaire, predictors were identified using multivariate regression models, and estimated cost was calculated. 716 eligible patients (mean age: 46.3 years) were included by 407 physicians. Nocturnal symptoms were reported in 50.8% of patients and exclusively diurnal symptoms in 49.2%. Mean work productivity and daily activities decreased by 31.4% and 32.6%, respectively (both p<0.001). Work productivity was influenced by symptom intensity, diurnal symptoms occurrence, regurgitation and diurnal sleepiness. The mean associated cost per patient/week (€313) was higher in patients with diurnal symptoms (without (€346) or with nocturnal (€312) symptoms) than in patients with exclusive nocturnal symptoms (€253) (p<0.001). Gastroesophageal reflux disease incurs high work productivity loss especially in patients with diurnal symptoms. Further medico-economic analyses are needed to estimate the cost effectiveness ratio according to therapeutic strategies. Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l.

Gastroesophageal reflux disease (GERD) is one of the main causes of chronic cough. We evaluated the role of microaspiration in the pathogenesis of reflux-related cough by determining the amount of lipid-laden macrophages (LLMs) in bronchoalveolar lavage (BAL) specimens. A total of 161 cases of chronic cough were evaluated, and 36 patients (average age 48.2 years) were recruited for this single center prospective study. Patients with a history of smoking, angiotensin converting enzyme inhibitor usage, any abnormality on pulmonary function tests, abnormal chest X-rays, occupational or environmental exposures, or upper airway cough syndrome were excluded. GERD was evaluated by 24-hour esophageal impedance-pH monitoring. BAL specimens for LLM determination were obtained from 34 patients by flexible bronchoscopy. Patients with pathological intra-esophageal reflux according to multichannel intraluminal impedance and pH monitoring had higher LLM positivity in BAL specimens than patients without pathological reflux (8/14 in reflux positive group vs 1/22 in reflux negative group; P = 0.004). The BAL cell distribution was not different between the 2 groups ( P = 0.574 for macrophages, P = 0.348 for lymphocytes, P = 0.873 for neutrophils and P = 0.450 for eosinophils). Our results confirm the role of the microaspiration of refluxate in the pathogenetic mechanism of chronic cough. While bronchoscopy is indicated in patients with chronic cough, in addition to the routine airway evaluation, BAL and LLM detection should be performed. LLM can be used to diagnose aspiration in reflux-related chronic cough. Future studies are needed to evaluate the response to anti-reflux medications or surgery in patients with LLM positivity.

Unlike cigarettes, there is little information about the association between other tobacco products and the risk of gastroesophageal reflux disease (GERD) and esophageal adenocarcinoma. We used the baseline data from the Pars Cohort Study conducted in southern Iran. In 2012, 9264 local residents between 40 and 75 years old were enrolled, with detailed information about lifestyle, including duration and frequency of tobacco use. GERD was defined based on questions assessing heartburn and regurgitation in the past 12 months, frequency and severity. Associations were calculated by logistic regression models adjusted for age, sex, education, cigarettes and body mass index. In the study, 25.4% of the participants had severe GERD (interfering with participants' routines), 25.1% had frequent GERD (at least once a week) and 11.2% had both severe and frequent GERD, all more common among women (p < 0.001); 45.6% of women and 28.3% of men smoked waterpipes. Among people not using medications against reflux symptoms, there was an association between waterpipe smoking and severe [odds ratio (OR) = 1.18; 95% confidence interval (CI):1.04-1.35], frequent (OR = 1.16; 95% CI: 1.02-1.32) and severe and frequent reflux (OR = 1.30; 95% CI: 1.08-1.56). The associations increased with the duration of use, intensity and cumulative waterpipe-years, reaching an OR of 1.44 (95% CI: 1.12-1.86) for severe and frequent reflux in those who had smoked more than 48 waterpipe-years. There was effect modification by sex, and all the associations were only seen among women. The increasing trend in the association between cumulative waterpipe use and reflux disease among women is particularly important given the growing waterpipe tobacco epidemic in many populations.

Sensitization of esophageal chemoreceptors, either directly by intermittent acid exposure or indirectly through esophagitis-associated inflammatory mediators, is likely to be the mechanism underlying the perception of heartburn. To compare basal esophageal sensitivity with electrical stimulation and acid, and to compare the degree of acid-induced sensitization in controls and in patient groups across the entire spectrum of gastroesophageal reflux disease: erosive oesophagitis (EO), nonerosive reflux disease (NERD), and functional heartburn (FH). Esophageal sensory and pain thresholds to electrical stimulation were measured before, 30, and 60 minutes after an intraesophageal infusion of saline or HCl. Patients received a 30-minute infusion of 0.15 M HCl and controls were randomized to receive either HCl (n = 11) or saline (n = 10). After electrical sensory threshold testing, participants received another 30-minute infusion of HCl to determine whether sensitivity to acid is increased by prior acid exposure All patient groups had higher basal sensory thresholds than healthy controls (controls, 13 ± 1.4 mA; FH, 20 ± 5.1 mA; NERD, 21 ± 5.1 mA; EO, 23 ± 5.4 mA; P < 0.05). Acute esophageal acid exposure reduced sensory thresholds to electrical stimulation in FH and NERD patients (P < 0.05). The level of acid sensitivity during the first HCl infusion was comparable between all patient groups and controls. The secondary infusion caused increased discomfort in all participants (P < 0.01). This acid-induced sensitization to HCl was significantly elevated in the patient groups ( P < 0.05). (1) Esophageal acid infusion sensitizes it to subsequent electrical and chemical stimulation. (2) The acid-related sensitization is greater in gastroesophageal reflux disease than in controls and may influence in part symptom perception in this population. (3) Acid-related sensitization within the gastroesophageal reflux disease population is not dependant on mucosal inflammation.

This study was conducted to provide sonographic measurements of the abdominal esophagus length in neonates and infants with and without gastroesophageal reflux disease (GERD) and to investigate its diagnostic value. GERD severity was also evaluated and correlated with esophageal length. It is a prospective case-control study. This prospective case-control study comprised 235 neonates and infants (120 without reflux and 115 with reflux). There were 40 children without reflux in each of three age categories: less than 1 month, 1-6 months, and 6-12 months. Of the children with reflux, 40 were less than 1 month old; 37, 1-6 months; and 38, 6-12 months. The abdominal esophagus was measured from its entrance into the diaphragm to the base of gastric folds in fed infants. GERD was sonographically diagnosed and confirmed by a barium meal. The number of refluxes during a 10-min period were recorded. Neonates and infants with reflux had a significantly shorter abdominal esophagus than subjects without reflux: the mean difference in neonates, 4.65 mm; 1-6 months, 4.57 mm; 6-12 months, 3.61 mm. Children with severe reflux had a shorter esophagus compared with those with mild and moderate reflux only in the neonate group. Therefore, thinking of GERD and carefully looking for its symptoms is necessary to avoid unnecessary utilization of healthcare resources in children with severe reflux.

Gastroesophageal reflux disease (GERD) can be classified into erosive reflux disease (ERD) and nonerosive gastroesophageal reflux disease (NERD). We aimed to compare the recurrence rates of ERD and NERD and determine the risk factors related to the recurrence. This prospective study comprised 337 consecutive adults who completed questionnaires on their GERD symptoms, height, weight, sleeping position, dinner time, and bedtime. During upper gastrointestinal endoscopy, the presence of a hiatal hernia and mucosal breaks in the low esophagus, esophageal length (the distance between the Z-line and the incisors), and the esophageal length-to-height ratio were recorded. Recurrence was diagnosed when the patient required additional proton pump inhibitor medication after initial recovery with 4-8 weeks of treatment. Recurrence was experienced by 47 (26.0%) of 181 GERD patients. The recurrence rate did not differ between the 48 ERD (27.1%) and 133 NERD (25.6%) patients (P = 0.849). Of the various factors studied, recurrence was found to be correlated with a dinner-to-bedtime interval of less than 3 h (P = 0.002), globus sensation (P = 0.031), and old age (P = 0.047). Logistic regression analysis revealed that a short interval between dinner and bedtime was the only factor significantly related to the recurrence (P = 0.002). Both ERD and NERD patients who sleep within 3 h after eating have a higher risk of GERD recurrence. Our findings highlight the impact of a short dinner-to-bedtime interval on the recurrence of GERD (ClinicalTrials.gov ID: KCT0000134). © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

Gastroesophageal reflux disease (GERD) therapy is challenging and suppression of acid secretion or prokinetics do not cure all cases. Some drugs with protective action on the esophageal mucosa have been used alternatively or in association with proton pump inhibitors (PPIs) and/or prokinetics. The Romanian Society of Neurogastroenterology undertook an Evidence-Based analysis, from which this position paper evolved. We performed a systematic literature search in PubMed until October 2015, using the terms: sucralfate, guaiazulene, gaiazulene, dimethicone, alginate, antacids and gastroesophageal reflux. Forty-seven papers were included and analyzed. Several statements were elaborated regarding the use of these drugs in GERD. The evidence and recommendations were discussed between the authors. There is evidence in the medical literature suggesting the benefit of these drugs in GERD. In patients with persistent or mild reflux symptoms antacids rapidly relieve heartburn. Alginate-antacid combination is superior both over placebo and antacids to treat mild reflux symptoms, and can be used to treat persistent reflux symptoms despite acid suppressant therapy. Sucralfate is superior over placebo in alleviating GERD symptoms and can be used as maintenance therapy. Guaiazulene-dimethicone improves the quality of life in patients with GERD. Drugs used to protect the esophageal mucosa against acid are useful in alleviating chronic heartburn, especially in patients with mild reflux symptoms.

Pathological bolus exposure may define gastro-esophageal reflux better than pathological acid exposure in patients with globus.

Conventionally, pathological acid exposure (PAE), defined by acid reflux only, is used to identify gastro-esophageal reflux disease (GERD). However, weak acid reflux or non-acid reflux also induces reflux symptoms. Defining abnormal reflux based on all reflux episodes may better identify GERD and would be more useful among patients with atypical GERD symptoms, such as globus. Impedance-pHmetry results of 31 globus patients, off acid suppressants, were analysed. A median of 24 episodes of reflux were observed. Of the reflux episodes, 54% were non-acid reflux and 50% reached the proximal extent. PAE was observed in 6 patients (19%). For 5 patients (16%) without PAE, there was evidence of increased bolus exposure compared to normal controls (an intraesophageal bolus exposure for more than 1.4% of the recording time, defined as pathological bolus exposure, PBE). When GERD was defined by PAE or esophagitis, the prevalence of GERD was 29%. When GERD was defined by PBE, PAE or esophagitis, the prevalence was 42%. PBE identified 13% of the patients who otherwise would have been missed. A significant proportion of patients without PAE had evidence of PBE. PBE may be a more useful definition for identifying patients with abnormal increase in reflux in patients with globus. Further studies are warranted.

The purpose of this study was to determine the relation between posturally increased intra-abdominal pressure and lower/upper esophageal sphincter pressure changes in patients with gastroesophageal reflux disease. We used high resolution manometry to measure pressure changes in lower and upper esophageal sphincter during bilateral leg rise. We also examined whether the rate of lower and upper esophageal sphincter pressure would increase during leg raise differentially in individuals with versus without normal resting pressure. Fifty eight patients with gastroesophageal reflux disease participated in the study. High resolution manometry was performed in relaxed supine position, then lower and upper esophageal sphincter pressure was measured. Finally, the subjects were instructed to keep their legs lifted while performing 90-degree flexion at the hips and knees and the pressure was measured again. Paired t-test and independent samples t-test were used. There was a significant increase in both lower (P < 0.001) and upper esophageal sphincter pressure (P = 0.034) during leg raise compared to the initial resting position. Individuals with initially higher pressure in lower esophageal sphincter (>10 mmHg) exhibited a greater pressure increase during leg raise than those with initially lower pressure (pressure ≤10 mmHg; P = 0.002). Similarly individuals with higher resting upper esophageal sphincter pressure (>44 mmHg) showed a greater pressure increase during leg raise than those with lower resting pressure (≤44 mmHg; P < 0.001). The results illustrate the influence of postural leg activities on intraesophageal pressure in patients with gastroesophageal reflux disease, indicating by means of high resolution manometry that diaphragmatic postural and sphincter function are likely interrelated in this population.

Background Using esophageal pHmetry, nasal CPAP (nCPAP) has been shown to decrease acid gastroesophageal reflux (GER) in adult humans. Although both GER (mainly non-acid) and nCPAP use are very frequent in newborns, the effect of nCPAP on GER in early life is unknown. Having recently shown that the newborn lamb is a unique model for studying neonatal GER, our main objective was to assess the effect of nCPAP on GER in newborn lambs. Methods Eight newborn lambs, aged 2–3 days, were studied. Continuous esophageal pH-Impedance monitoring and polysomnography were performed for six hours during both spontaneous breathing and nCPAP application at 6 cmH2O (nCPAP6), in a randomized order. Results were compared in the two experimental conditions, as well as without CPAP during the following 6 hours. Results i) nCPAP6 virtually abolished GER [mean ±SD reflux number for 6 h = 9.1±8.6 without nCPAP6 vs. 0.6±1 with nCPAP6, P<0.05]; ii) GER number was also reduced during the 6 h-period following nCPAP6 application (18±16 without nCPAP6 vs. 7±8.1 with nCPAP6, P<0.05); iii) nCPAP6 decreased the depth and duration of lower esophageal sphincter relaxation. Conclusions nCPAP inhibits GER in the newborn lamb. Further clinical studies using different levels of nasal CPAP are needed to confirm this result in human infants. PMID:25226514

Background Women conceiving following in vitro fertilization (IVF) likely have a variety of risk factors that predispose them to gastroesophageal reflux disease (GERD) in the future. Objective We aimed to investigate whether pregnancy through IVF may predispose to subsequent GERD compared with pregnancies without IVF. We also evaluate whether twin IVF pregnancies lead to additional risk for having GERD compared with singleton IVF pregnancies. Methods A validated reflux questionnaire was administered to 156 women with singleton (n = 102) or twin (n = 54) IVF birth (IVF group) and 111 women with a naturally conceived singleton birth (control group). All women included in the study were primiparas who had given birth at least 1 year prior to data collection. The diagnosis of GERD was based on the occurrence of typical symptoms (heartburn, regurgitation, or both) at least once a week. Results The prevalence of GERD was 13.5% and 4.5% in IVF and control groups (p = 0.015); in the IVF group, this was slightly higher, but not statistically significant, in women with twin compared with singleton pregnancies (14.8% vs. 12.7%, p = 0.749). Logistic regression analysis showed that IVF was strongly associated with subsequent GERD (OR, 3.30; 95% CI 1.20–9.04; p = 0.02). Conclusion The risk of developing GERD at least 1 year after delivery increased following IVF. Long-term follow-up studies are required to determine whether therapy during pregnancy can prevent this risk. PMID:27087950

The association of gastro-esophageal reflux (GER) with a wide variety of pulmonary disorders was recognized. We aimed to evaluate the effect of GER-induced esophagitis on airway hyper-reactivity (AHR) in patients and the response to treatment. In this cohort study, 30 patients attending the gastrointestinal clinic of a university hospital with acid reflux symptoms were included. All patients were evaluated endoscopically and divided into case group with esophagitis and control group without any evidence of esophagitis. Spirometry and methacholine test were done in all patients before and after treatment of GER with pantoprazole 40 mg daily for six months. There was a significant difference in the rate of positive methacholine test between the cases (40%) and the controls (6.7%) prior to anti-acid therapy (P < 0.0001). After six months of treatment, the frequency of positive methacholine test diminished from 40 to 13.3% in the case group (P < 0.05) but did not change in the controls (P = 0.15). The presence of esophagitis due to GER would increase the AHR and treatment with pantoperazole would decrease AHR in patients with proved esophagitis and no previous history of asthma after six months.

To evaluate the relationship between laryngopharyngeal reflux disease and presence of lumbar kyphosis. A cross-sectional study. We included 20 patients with lumbar kyphosis and 31 control subjects. A diagnosis of laryngopharyngeal reflux disease and gastroesophageal reflux disease was made if the Reflux Symptom Index score was ≥13 and if the Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease was ≥8, respectively. We compared the prevalence of the two reflux diseases, frequent reflux symptoms, and demographic factors between the two groups. There was no significant difference in demographic factors between the two groups. Five (25%) of 20 patients with lumbar kyphosis had a Reflux Symptom Index ≥13 compared with one (3.2%) of 31 controls. Seven (35.0%) of 20 patients had a Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease ≥8 compared with three (9.7%) of 31 controls. A comparison of the prevalence of laryngopharyngeal reflux disease and gastroesophageal reflux disease showed a significant difference between patients with kyphosis and controls (P value = 0.029 and 0.036, respectively). In Reflux Symptom Index, heartburn, hoarseness, and a swallowing problem were significantly frequent symptoms in the kyphosis group compared with the control group. The prevalence of laryngopharyngeal reflux disease and gastroesophageal reflux disease was significantly higher in patients with lumbar kyphosis than in controls. Therefore, otolaryngologists and orthopedic surgeons should be aware that patients with lumbar kyphosis are likely to have gastroesophageal reflux disease and also laryngopharyngeal reflux disease.

This study was designed to investigate the frequency of gastroesophageal reflux disease (GERD) in children with functional constipation (FC). It was structured to assess the improvement level in reflux symptoms by measuring the acid reflux in these patients after they had received FC treatment. Ninety-four children who suffered from constipation were evaluated prospectively. Data forms were completed to assess the GERD symptoms in all the cases. Twenty-four-hour pH meter monitoring was performed in 55 of the patients with GERD symptoms. The cases with abnormal acid reflux were treated by conventional therapy for FC. These cases were re-evaluated for GERD symptoms and weekly defecation frequency, and 24-h pH meter monitoring was performed at the end of a 3-month period. An abnormal level of acid reflux was determined in 23 of the 55 cases. After the constipation treatment, a significant improvement was achieved in the acid reflux index and GERD symptoms, whereas the weekly defecation frequency increased. GERD is a frequent problem in children with FC. Treatment of the constipation can improve the reflux symptoms and abnormal acid reflux in these cases. Physicians should bear in mind the co-occurrence of these two prevalent problems for better disease management.

Respiratory symptoms are a possible atypical clinical picture of gastro-esophageal reflux disease (GERD). However, a significant number of patients with GERD-related respiratory symptoms do not report improvement despite aggressive acid-suppressive therapy. Some of these refractory cases may be due to the recently appreciated entity of non-acid or weakly acidic reflux. The aim of our study is to assess the pH-impedance features of GER inducing airway symptoms, compared with GER inducing typical gastro-intestinal (GI) symptoms. We prospectively enrolled infants and children with GERD-related respiratory symptoms from January 2015 to December 2015. Age- and sex-matched patients with GERD-related GI symptoms were enrolled as comparison group. The overall number, the acidity pattern, and the height of reflux episodes were compared between the two groups. Forty patients (M/F: 20/20; mean age: 58.3 months) were enrolled in the study group and 40 in the comparison group. The mean acid exposure index was 7.9% within the study group and 15.9% within the comparison group (p:0.026). Children with respiratory symptoms versus children with GI symptoms had a mean of 40.8 acid reflux episodes versus 62.4 (p:0.001), a mean of 2.2 weakly acid reflux episodes versus 20.1 (p:0.002), and a mean of 22.1 weakly alkaline reflux episodes versus 10.2 (P < 0.001). Separate analysis of both infants and children was performed. The main finding of this prospective, controlled study is that children >1 year with GERD-related respiratory symptoms showed a significantly higher number of weakly alkaline refluxes than children with GERD-related GI symptoms. This supports the hypothesis that respiratory symptoms are less related to acidity than GI symptoms. Pediatr Pulmonol. 2017;52:669-674. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Recent data from the studies conducted in the Western countries have proved that patients with gastroesophageal reflux disease have significantly impaired health-related quality of life compared to general population. The study is aimed at evaluating the burden of reflux symptoms on patients'health-related quality of life. The study involved 1,593 patients with diagnosed gastroesophageal reflux disease.The Serbian version of a generic self-administered Centers for Disease Control and Prevention questionnaire was used. Statistical analyses included descriptive statistics, Pearson chi-square test and a multiple regression model. Among all participants, 43.9% reported fair or poor health. Mean value of unhealthy days during the past 30 days was 10.4 days, physically unhealthy days 6.4 days, mentally unhealthy days 5.3 days and activity limitation days 4.3 days. Furthermore, 24.8% participants reported having ≥ 14 unhealthy days, 14.9% had 14 physically unhealthy days, 11.8% reported 14 mentally unhealthy days, and 9.4% had ≥ 14 activity limitation days. This study addressed complex relationships between reflux symptoms and patients'impaired everyday lives.

Multichannel impedance pH monitoring has shown that weakly acidic refluxes are able to generate heartburn. However, data on the role of different pH values, ranging between 4 and 7, in the generation of them are lacking. The aim of this study was to evaluate whether different pH values of weakly acidic refluxes play a differential role in provoking reflux symptoms in endoscopy-negative patients with physiological esophageal acid exposure time and positive symptom index and symptom association probability for weakly acidic refluxes. One hundred and forty-three consecutive patients with gastroesophageal reflux disease, nonresponders to proton pump inhibitors (PPIs), were allowed a washout from PPIs before undergoing: upper endoscopy, esophageal manometry, and multichannel impedance pH monitoring. In patients with both symptom index and symptom association probability positive for weakly acidic reflux, each weakly acidic reflux was evaluated considering exact pH value, extension, physical characteristics, and correlation with heartburn. Forty-five patients with normal acid exposure time and positive symptom association probability for weakly acidic reflux were identified. The number of refluxes not heartburn related was higher than those heartburn related. In all distal and proximal liquid refluxes, as well as in distal mixed refluxes, the mean pH value of reflux events associated with heartburn was significantly lower than that not associated. This condition was not confirmed for proximal mixed refluxes. Overall, a low pH of weakly acidic reflux represents a determinant factor in provoking heartburn. This observation contributes to better understand the pathophysiology of symptoms generated by weakly acidic refluxes, paving the way toward the search for different therapeutic approaches to this peculiar condition of esophageal hypersensitivity. © 2014 International Society for Diseases of the Esophagus.

Gender difference in gastro-esophageal reflux diseases.

The incidence of esophageal adenocarcinoma (EAC) has risen sharply in western countries over the past 4 decades. This type of cancer is considered to follow a transitional process that goes from gastro-esophageal reflux disease (GERD) to Barrett's esophagus (BE, a metaplastic condition of the distal esophagus), a precursor lesion and ultimately adenocarcinoma. This spectrum of GERD is strongly predominant in males due to an unidentified mechanism. Several epidemiologic studies have described that the prevalence of GERD, BE and EAC in women is closely related to reproductive status, which suggests a possible association with the estrogen level. Recently, we revealed in an in vivo study that the inactivation of mast cells by the anti-inflammatory function of estrogen may account for the gender difference in the GERD spectrum. Other studies have described the contribution of female steroid hormones to the gender difference in these diseases. Estrogen is reported to modulate the metabolism of fat, and obesity is a main risk factor of GERDs. Moreover, estrogen could confer esophageal epithelial resistance to causative refluxate. These functions of estrogen might explain the approximately 20-year delay in the incidence of BE and the subsequent development of EAC in women compared to men, and this effect may be responsible for the male predominance. However, some observational studies demonstrated that hormone replacement therapy exerts controversial effects in GERD patients. Nevertheless, the estrogen-related endocrine milieu may prevent disease progression toward carcinogenesis in GERD patients. The development of innovative alternatives to conventional acid suppressors may become possible by clarifying the mechanisms of estrogen.

Gastroesophageal reflux disease (GERD) is a major digestive health problem with a high and increasing incidence worldwide. Peroral endoscopic cardial constriction (PECC) was developed by our group to provide a less invasive treatment for GERD.In this preliminary follow-up study, 16 patients were enrolled and 13 patients with GERD were targeted for analysis according to the Los Angeles classification of reflux esophagitis. The GERD health-related quality of life (GERD-HRQL) scale and esophageal pH monitoring were applied to assess clinical efficiency at 3 and 6 months after PECC treatment, respectively.All GERD patients successively received PECC, and no severe treatment-related complication was reported. Before PECC treatment, the GERD-HRQL scale was 19.92 ± 7.89. At 3 and 6 months after treatment, the GERD-HRQL scale was 4.46 ± 4.31 and 5.69 ± 5.07, respectively. DeMeester score was 125.50 ± 89.64 before PECC treatment, and 16.97 ± 12.76 and 20.32 ± 15.22 at 3 and 6 months after PECC treatment. Furthermore, the fraction time of a pH below 4 significantly decreased at 3 and 6 months after PECC treatment. Fraction time at pH <4 was 35.55 ± 26.20 before PECC treatment and 7.96 ± 13.03 and 4.72 ± 3.78 at 3 and 6 months after PECC treatment, respectively. These results suggest that PECC treatment could significantly reduce the GERD-HRQL scale and DeMeester score (P < .01).PECC is a feasible, safe, and effective method to treatment GERD through narrowing the diameter of the cardia and preventing the reflux of stomach contents.

The incidence of gastroesophageal reflux disease (GERD) is increasing in Korea. The aim of this study was to evaluate the relationship between GERD symptoms and dietary factors in Korea. From January 2007 to April 2008, 162 subjects were enrolled (81 in GERD group and 81 in control group). They were asked to complete the questionnaires about GERD symptoms and dietary habits. The symptom severity score was recorded by visual analogue scale. Subjects with overweight or obesity had an increased risk for GERD (OR, 2.52; 95% CI, 1.18-5.39). Irregular dietary intake was one of the risk factors for GERD (OR, 2.33; 95% CI, 1.11-4.89). Acid regurgitation was the most suffering (2.85 ± 2.95 by visual analogue scale) and frequent reflux-related symptom (57.5%) in GERD. Noodles (OR, 1.22; 95% CI, 1.12-1.34), spicy foods (OR, 1.09; 95% CI, 1.02-1.16), fatty meals (OR, 1.20; 95% CI, 1.09-1.33), sweets (OR, 1.42; 95% CI, 1.00-2.02), alcohol (OR, 1.16; 95% CI, 1.03-1.31), breads (OR, 1.17; 95% CI, 1.01-1.34), carbonated drinks (OR, 1.69; 95% CI, 1.04-2.74) and caffeinated drinks (OR,1.41; 95% CI, 1.15-1.73) were associated with symptom aggravation in GERD. Among the investigated noodles, ramen (instant noodle) caused reflux-related symptoms most frequently (52.4%). We found that noodles, spicy foods, fatty meals, sweets, alcohol, breads, carbonated drinks and caffeinated drinks were associated with reflux-related symptoms.

Belching may result from transient lower esophageal sphincter relaxation; therefore, it has been proposed that belching may be a manifestation of gastroesophageal reflux disease (GERD). This study was conducted to investigate the frequency of belching during esophagogastroduodenoscopy (EGD) and its association with GERD. A retrospective review was performed on prospectively collected clinical and endoscopic data from 404 subjects who underwent EGD without sedation from December 2012 to May 2013 in a training hospital in Korea. All detectable belching events during endoscopy were counted. Frequency and severity of belching events were compared between the group with and without GERD using an ordinal logistic regression model. There were 145 GERD patients (26 erosive reflux disease and 119 nonerosive reflux disease [NERD]). In the multivariable analysis, GERD was significantly associated with a higher frequency of belching events (odds ratio = 6.59, P < 0.001). Central obesity, female, and younger age were also risk factors for frequent belching during EGD. Subgroup analyses were performed in subjects without erosive reflux disease (n = 378) and NERD (n = 293). NERD was also a predictive factor for frequent belching during EGD (odds ratio = 6.61, P < 0.001), and the frequency of belching was significantly correlated with GERD severity according to the Los Angeles classification (P < 0.05). Frequent belching during EGD was associated with GERD, including NERD. Future research should focus on its adjuvant role in the diagnosis of GERD/NERD and the necessity for applying differentiated endoscopy strategies for GERD patients, leading to less discomfort during EGD in patients at risk for intolerability. © 2015 International Society for Diseases of the Esophagus.

Alginate rafts (polysaccharide polymers that precipitate into a low-density viscous gel when they contact gastric acid) have been reported to form at the acid pocket, an unbuffered pool of acid that floats on top of ingested food and causes postprandial acid reflux. We studied the location of an alginate formulation in relation to the acid pocket and the corresponding effects on reflux parameters and acid pocket positioning in patients with gastroesophageal reflux disease (GERD). We randomly assigned patients with symptomatic GERD and large hiatal hernias to groups who were given either (111)In-labeled alginate-antacid (n = 8, Gaviscon Double Action Liquid) or antacid (n = 8, Antagel) after a standard meal. The relative positions of labeled alginate and acid pocket were analyzed for 2 hours by using scintigraphy; reflux episodes were detected by using high-resolution manometry and pH-impedance monitoring. The alginate-antacid label localized to the acid pocket. The number of acid reflux episodes was significantly reduced in patients receiving alginate-antacid (3.5; range, 0-6.5; P = .03) compared with those receiving antacid (15; range, 5-20), whereas time to acid reflux was significantly increased in patients receiving alginate-antacid (63 minutes; range, 23-92) vs those receiving antacid (14 minutes; range, 9-23; P = .01). The acid pocket was located below the diaphragm in 71% of patients given alginate-antacid vs 21% of those given antacid (P = .08). There was an inverse correlation between a subdiaphragm position of the acid pocket and acid reflux (r = -0.76, P < .001). In a study of 16 patients with GERD, we observed that the alginate-antacid raft localizes to the postprandial acid pocket and displaces it below the diaphragm to reduce postprandial acid reflux. These findings indicate the importance of the acid pocket in GERD pathogenesis and establish alginate-antacid as an appropriate therapy for postprandial acid reflux. Copyright © 2013 AGA Institute

Gastroesophageal reflux disease and non-digestive tract diseases.

Over the past decade, incidence of gastroesophageal reflux disease (GERD) showed an increasing trend resulting from factors, including lifestyle and dietary habits; however, both etiology and pathological mechanisms remain controversial. GERD occurs as a result of a variety of mechanisms and there is no single factor. Symptoms of GERD are often non-typical, with a likelihood of being overlooked by non-gastroenterology professionals. Therefore, improving GERD awareness in non-gastroenterology practitioners, along with early diagnosis and treatment, provide potential benefit to clinicians and patients alike. Increasing evidence suggests GERD has specific connections with a variety of non-digestive tract conditions, may contribute an aggravating compounding effect on other diseases, prolong hospitalization, and increase subsequent medical costs. This review considers and emphasizes the association between GERD and non-digestive tract conditions, including atrial fibrillation, chronic obstructive pulmonary disease, primary pulmonary fibrosis and energy metabolism related to diet.

To investigate the effect of dietary fiber on symptoms and esophageal function testing parameters in non-erosive gastroesophageal reflux disease (GERD) (NERD) patients. Thirty-six NERD patients with low (< 20 g/d) dietary fiber intake were enrolled in the study. They were examined with the use of symptom questionnaire (GERD-Q), high-resolution esophageal manometry, 24-h esophageal pH-impedance examinations, and food frequency questionnaire before and after 10 d of usual diet supplemented by psyllium 5.0 g TID. Complete data of 30 patients were available to the final analysis. The obtained results were analyzed with the use of non-parametric statistics (Wilcoxon matched pairs test). The number of patients experiencing heartburn was less (93.3% at baseline vs 40% at the end of the study, P < 0.001) and the GERD-Q score decreased (mean ± SD: 10.9 ± 1.7 vs 6.0 ± 2.3, P < 0.001) after the treatment period. Minimal resting lower esophageal sphincter (LES) pressure increased from 5.41 ± 10.1 to 11.3 ± 9.4 mmHg ( P = 0.023), but no change in residual LES pressure and mean resting pressure was found. Total number of gastroesophageal refluxes (GER) decreased from 67.9 ± 17.7 to 42.4 ± 13.5 ( P < 0.001) predominantly by acid and weak acid types of GERs. No significant change in mean esophageal pH and % of time pH < 4 was registered. Maximal reflux time decreased from 10.6 ± 12.0 min to 5.3 ± 3.7 min ( P < 0.05). Fiber-enriched diet led to a significant increase of minimal lower esophageal sphincter resting pressure, a decrease of number of gastroesophageal refluxes, and a decrease of heartburn frequency per week in NERD.

The prevalence of gastroesophageal reflux disease (GERD) and the incidence of some of its complications have risen strikingly over the last few decades. With the increase in our understanding of the pathophysiology of GERD along with the development of proton pump inhibitors, the diagnostic and therapeutic approaches to GERD have changed dramatically over the past decade. However, GERD still poses a problem to many clinicians since the spectrum of the disease has evolved to encompass more challenging presentations such as refractory GERD and extra-esophageal manifestations. The aim of this article is to provide a review of available current translational research on GERD. This review includes acid pocket, ambulatory pH monitoring, impedance pH monitoring, mucosa impedance, and high resolution manometry. This article discusses current translational research on GERD.

Widespread epidemiological changes, rising prevalence and gradual shifts in patterns of disease manifestations: this is the changing face of gastroesophageal reflux disease (GERD) in Asia. Are we witnessing a disease in evolution or merely the result of increased and more accurate case reporting that comes with advancing diagnostic technology, better medical facilities and heightened awareness of the disease? Do the figures reported really reflect the actual scenario or is there more to it than meets the eye? In this article, we take you back in time to review relevant developments over the past decade or so. We will draw on findings from across Asia, take an in-depth look at prevailing trends and patterns and examine some of the most plausible explanations behind the dynamics of this epidemiological transition.

Atrial fibrillation and gastroesophageal reflux disease: the cardiogastric interaction.

Atrial fibrillation (AF) is the most common sustained arrhythmia and is associated with significant morbidity and mortality. Multiple conditions like hypertension, heart failure, diabetes, sleep apnoea, and obesity play a role for the initiation and perpetuation of AF. Recently, a potential association between gastroesophageal reflux disease (GERD) and AF development has been proposed due to the close anatomic vicinity of the oesophagus and the left atrium. As an understanding of the association between acid reflux disease and AF may be important in the global multimodal treatment strategy to further improve outcomes in a subset of patients with AF, we discuss potential atrial arrhythmogenic mechanisms in patients with GERD, such as gastric and subsequent systemic inflammation, impaired autonomic stimulation, mechanical irritation due to anatomical proximity of the left atrium and the oesophagus, as well as common comorbidities like obesity and sleep-disordered breathing. Data on GERD and oesophageal lesions after AF-ablation procedures will be reviewed. Treatment of GERD to avoid AF or to reduce AF burden might represent a future treatment perspective but needs to be scrutinized in prospective trials.

OBJECTIVE To compare the incidence of and risk factors for gastroesophageal reflux (GER) and regurgitation associated with preanesthetic food withholding for periods of 18 hours (overnight) and 3 hours in healthy dogs undergoing elective orthopedic surgery. ANIMALS 82 healthy (American Society of Anesthesiologists physical status classification I or II) client-owned dogs. PROCEDURES Food was withheld for 18 hours (18-hour group [n = 41]) or each dog was allowed to consume half its daily ration of canned food approximately 3 hours (3-hour group [n = 41]) prior to induction of anesthesia. In each anesthetized dog, a pH catheter was introduced through the oropharynx into the distal portion of the esophagus; the pH was continuously recorded throughout the period of anesthesia. Gastroesophageal reflux was defined as pH < 4.0. RESULTS Gastroesophageal reflux was significantly associated with age, dorsal recumbency, and duration of preanesthetic food withholding. Regurgitation was significantly associated with duration of GER and duration of preanesthetic food withholding. During anesthesia, 25 (61%) dogs in the 3-hour group had GER and 12 (48%) of those dogs regurgitated gastric content; 18 (43.9%) dogs in the 18-hour group had GER and 2 (11.1%) of those dogs regurgitated gastric content. The mean lowest pH measured in the refluxate in the 3-hour group (2.3) was significantly greater than that in the 18-hour group (1.3). CONCLUSIONS AND CLINICAL RELEVANCE Among the study dogs undergoing orthopedic surgery, consumption of a light meal 3 hours prior to anesthesia was associated with significantly greater odds of reflux and regurgitation, compared with overnight food withholding.

Since the development of ambulatory esophageal pH monitoring test to diagnose gastroesophageal reflux disease (GERD), several parameters have been introduced. The aim of this study was to assess whether using the symptom index (SI), symptom sensitivity index (SSI), and symptom association probability (SAP), in addition to the DeMeester score (DS), would be useful for interpreting the Bravo pH monitoring test. A retrospective study, which included 68 patients with reflux symptoms refractory to proton pump inhibitor (PPI) therapy who underwent a Bravo capsule pH test between October 2006 and May 2015, was carried out. Acid reflux parameters and symptom reflux association parameters were analyzed. The median percent time of total pH<4 and DS were 2.90% (interquartile range [IQR] 1.13-6.03%) and 11.10 (IQR 4.90-22.80), respectively. According to the analysis of the day-to-day variation in percent time of total pH<4 (r=0.724) and DS (r=0.537), there was a significant correlation between Day 1 and Day 2. The positive rate of Bravo test according to DS was 27 (39.7%). Although thirty patients experienced symptoms during the test, there were no significant differences of reflux parameters compared with other patients. In the symptom group, 7 patients (23.3%) were identified as having negative DS and an abnormal symptom-related index. There were no significant test-related complications. In addition to the analysis of traditional acid parameters of the Bravo capsule pH test, diagnosis of GERD, including reflux hypersensitivity, can be improved by performing an analysis of the symptom-reflux association and of the day-to-day variation.

An international group of experts evaluated and revised recommendations for ambulatory reflux monitoring for the diagnosis of gastro-esophageal reflux disease (GERD). Literature search was focused on indications and technical recommendations for GERD testing and phenotypes definitions. Statements were proposed and discussed during several structured meetings. Reflux testing should be performed after cessation of acid suppressive medication in patients with a low likelihood of GERD. In this setting, testing can be either catheter-based or wireless pH-monitoring or pH-impedance monitoring. In patients with a high probability of GERD (esophagitis grade C and D, histology proven Barrett's mucosa >1 cm, peptic stricture, previous positive pH monitoring) and persistent symptoms, pH-impedance monitoring should be performed on treatment. Recommendations are provided for data acquisition and analysis. Esophageal acid exposure is considered as pathological if acid exposure time (AET) is greater than 6% on pH testing. Number of reflux episodes and baseline impedance are exploratory metrics that may complement AET. Positive symptom reflux association is defined as symptom index (SI) >50% or symptom association probability (SAP) >95%. A positive symptom-reflux association in the absence of pathological AET defines hypersensitivity to reflux. The consensus group determined that grade C or D esophagitis, peptic stricture, histology proven Barrett's mucosa >1 cm, and esophageal acid exposure greater >6% are sufficient to define pathological GERD. Further testing should be considered when none of these criteria are fulfilled. © 2017 John Wiley & Sons Ltd.

To analyze the potential relationship between gastroesophageal reflux disease (GERD) and the development of atrial fibrillation (AF). Using the key words "atrial fibrillation and gastroesophageal reflux", "atrial fibrillation and esophagitis, peptic", "atrial fibrillation and hernia, hiatal" the PubMed, EMBASE, Cochrane Library, OVIDSP, WILEY databases were screened for relevant publications on GERD and AF in adults between January 1972-December 2013. Studies written in languages other than English or French, studies not performed in humans, reviews, case reports, abstracts, conference presentations, letters to the editor, editorials, comments and opinions were not taken into consideration. Articles treating the subject of radiofrequency ablation of AF and the consecutive development of GERD were also excluded. Two thousand one hundred sixty-one titles were found of which 8 articles met the inclusion criteria. The presence of AF in patients with GERD was reported to be between 0.62%-14%, higher compared to those without GERD. Epidemiological data provided by these observational studies showed that patients with GERD, especially those with more severe GERD-related symptoms, had an increased risk of developing AF compared with those without GERD, but a causal relationship between GERD and AF could not be established based on these studies. The mechanisms of AF as a consequence of GERD remain largely unknown, with inflammation and vagal stimulation playing a possible role in the development of these disorders. Treatment with proton pomp inhibitors may improve symptoms related to AF and facilitate conversion to sinus rhythm. Although links between AF and GERD exist, large randomized clinical studies are required for a better understanding of the relationship between these two entities.

Gastroesophageal reflux (GER) is a frequently occurring condition in infants capable of causing distressing symptoms. The aim of our study is to evaluate the efficacy of Mg alginate plus simethicone (Gastrotuss Baby, DMG Italia SRL, Pomezia, Italy), compared with rice-starch-thickened formula or with reassurance alone, in the treatment of GER in infants. The present randomized controlled trial was conducted in full-term infants affected by symptoms suggestive of GER, evaluated through a validated questionnaire (Infant Gastroesophageal Reflux Questionnaire Revised). The patients were randomized into 3 groups according to treatment (group A: Mg alginate plus simethicone; group B: thickened formula; group C: reassurance with lifestyle changes). Evaluation of symptom scores was performed after 1 month (T1) and 2 months (T2). A total of 64 (85.3%) of 75 enrolled infants (median age 5 months; range 1-10) concluded the study. After 1 month of treatment (T1), infants treated with Mg alginate plus simethicone showed a statistically significant improvement in symptoms compared with the thickened formula and reassurance (P < 0.03, <0.0001, respectively). At the end of the study, all 3 groups of patients showed a significant reduction in symptom scores (P < 0.002, <0.038, <0.03, respectively). Median symptom score values were more significantly reduced in group A than in group B and in group C (group A vs group B P < 0.002; group A vs group C P < 0.0001; group B vs group C P < 0.001). Mg alginate plus simethicone seems to be more efficacious on GER symptom scores than thickened formula and reassurance with lifestyle changes alone.

Associations of gastroesophageal reflux disease (GERD) with extraesophageal manifestations, such as chronic cough, asthma, and laryngitis, are reported frequently, and there is a strong evidence of biological plausibility in support of this relationship. On the other hand, extraesophageal reflux disease (EERD) is usually multifactorial in nature with reflux being just one of the several potential contributing cofactors. Moreover, the accuracy of currently available diagnostic tests for EERD is suboptimal, and therefore the causal relationship between GERD and EERD remains far from being conclusively proven. In addition, there is a general paucity of data supporting a beneficial effect of anti-reflux treatments on symptoms of patients with suspected EERD. Therefore, diagnostic as well as therapeutic management of EERD remains largely empirical. Current guidelines suggest an initial empiric trial of proton pump inhibitors in patients without alarm features, who present also typical GERD symptoms. For those patients who improve with PPIs, GERD is presumed to be the etiology. In patients with refractory reflux, combined impedance/pH monitoring might provide the single best strategy for evaluating reflux symptoms. In this context, as symptoms ascribable to GERD may depend on other causes, investigations that excludes GERD can help to redirect the diagnostic and treatment efforts to other pathological conditions. The present review intends to discuss the current state of knowledge regarding the challenging diagnostic and therapeutic management of patients with suspected EERD, emphasizing the points of strengths and limitations of currently available diagnostic options, and to provide an update on major diagnostic innovations in this area.

Insight Into the Relationship Between Gastroesophageal Reflux Disease and Asthma

Gastroesophageal reflux disease (GERD) is a common condition that presents with symptoms of heartburn and regurgitation. Asthma is an equally common medical condition that often coexists with GERD. The clinical scenario of difficult-to-treat asthma in the setting of concomitant GERD leads to the possibility of GERD-induced asthma. However, asthma may also induce GERD, so confusion has developed about the role of GERD in patients with moderate to severe asthma. Acid-suppressive therapy may be initiated in patients with asthma, but controlled studies have recently questioned the role of such therapy and, thus, have caused further confusion in this field. Recent advancements in the field of esophageal physiologic testing in GERD have introduced the concept of impedance–pH monitoring, which suggests a possible role of nonacid reflux in those who continue to be symptomatic despite acid-suppressive therapy. However, recent data caution about the role of surgical fundoplication based solely on the results of impedance monitoring. This article reviews current knowledge in the fields of GERD and asthma and suggests a possible treatment option for this group of patients. PMID:28435409

Diet and gastroesophageal reflux disease: role in pathogenesis and management.

PubMed

Sethi, Sajiv; Richter, Joel E

Gastroesophageal reflux disease (GERD) is a common disease that presents with a variety of symptoms including heartburn and acid regurgitation. Although dietary modification is currently regarded as first-line therapy for the disease, the role of diet in the pathogenesis and management of GERD is still poorly understood. The present article aims to review recent literature that examines the relationship of diet and GERD. Increased awareness of medications side effects and widespread overuse has brought nonpharmacological therapies to the forefront for the management of GERD. Recent findings have established the important role of nutrition for the managements of symptoms of GERD. Increasing scientific evidence has produced objective data on the role of certain trigger foods, whereas population studies endorse decreased reflux symptoms by following certain diets. Obesity has been linked with increased symptoms of GERD as well. Furthermore, the importance of lifestyle techniques such as head of bed elevation and increased meal to sleep time may provide nonpharmacologic methods for effective symptom control in GERD. We provide a comprehensive review on the association between diet and its role in the development and management of GERD.

The gastric accommodation response to meal intake determines the occurrence of transient lower esophageal sphincter relaxations and reflux events in patients with gastro-esophageal reflux disease.

Gastro-esophageal reflux (GER), the retrograde flow of gastric contents into the esophagus is a physiologic phenomenon, which can evoke symptoms and/or lesions in the esophagus (=gastro-esophageal reflux disease or GERD). Proton pump inhibitors (PPIs) reduce gastric acidity; however, as they are unable to control transient lower esophageal sphincter relaxations (TLESRs), the main mechanism for reflux in GERD, they do not abolish reflux. TLESRs occur predominantly in the postprandial period, and they are believed to be triggered by gastric distention. Gastric accommodation (GA) is the physiologic response to gastric distention and serves to prevent a rise in gastric wall tension during food intake. We aimed to study the relationship between GA and TLESRs, as they both are triggered by gastric distention. We studied 12 GERD patients (average age 37 years [range 18-62], 7m/5f) and nine healthy volunteers (average age 27 years [range 22-36], 2m/7f) using high resolution manometry-impedance measurement before and after a mixed meal challenge. We determined the number of TLESRs (with or without reflux) and measured pre- and postprandial IGP. The change in IGP between the pre- and postprandial period (ΔIGP) is used as surrogate for GA. We also measured LES pressure before and after the meal and calculated the change (ΔLESp). There were no statistical differences between pre- and postprandial IGP in GERD and healthy volunteers and similarly, there was no significant difference between pre- and postprandial LES pressures in GERD patients and healthy volunteers. The number of TLESRs (with or without reflux) was similar in GERD and healthy volunteers. More importantly, we did observe a negative correlation between ΔIGP and the number of TLESRs, irrespective of whether they were associated with reflux or not, in the GERD patients (without reflux r = -0.67, p = 0.017; with reflux r = -0.81, p = 0.0014). The same observations were found in healthy volunteers, where ΔIGP and

Laparoscopic sleeve gastrectomy (LSG) has reached wide popularity during the last 15 years, due to the limited morbidity and mortality rates, and the very good weight loss results and effects on comorbid conditions. However, there are concerns regarding the effects of LSG on gastroesophageal reflux disease (GERD). The interpretation of the current evidence is challenged by the fact that the LSG technique is not standardized, and most studies investigate the presence of GERD by assessing symptoms and the use of acid reducing medications only. A few studies objectively investigated gastroesophageal function and the reflux profile by esophageal manometry and 24-h pH monitoring, reporting postoperative normalization of esophageal acid exposure in up to 85% of patients with preoperative GERD, and occurrence of de novo GERD in about 5% of cases. There is increasing evidence showing the key role of the surgical technique on the incidence of postoperative GERD. Main technical issues are a relative narrowing of the mid portion of the gastric sleeve, a redundant upper part of the sleeve (both depending on the angle under which the sleeve is stapled), and the presence of a hiatal hernia. Concomitant hiatal hernia repair is recommended. To date, either medical therapy with proton pump inhibitors or conversion of LSG to laparoscopic Roux-en-Y gastric bypass are the available options for the management of GERD after LSG. Recently, new minimally invasive approaches have been proposed in patients with GERD and hypotensive LES: the LINX® Reflux Management System procedure and the Stretta® procedure. Large studies are needed to assess the safety and long-term efficacy of these new approaches. In conclusion, the recent publication of pH monitoring data and the new insights in the association between sleeve morphology and GERD control have led to a wider acceptance of LSG as bariatric procedure also in obese patients with GERD, as recently stated in the 5th International Consensus

Globus is a foreign body sense in the throat without dysphagia, odynophagia, esophageal motility disorders, or gastroesophageal reflux. The etiology is unclear. Previous studies suggested that increased upper esophageal sphincter pressure, gastroesophageal reflux and hypertonicity of esophageal body were possible etiologies. This study was to quantify the upper esophageal sphincter (UES) pressure, contractile front velocity (CFV), proximal contractile integral (PCI), distal contractile integral (DCI) and transition zone (TZ) in patient with globus gastroesophageal reflux disease (GERD) without globus, and normal controls to suggest the correlation of specific high-resolution manometry (HRM) findings and globus. Fifty-seven globus patients, 24 GERD patients and 7 normal controls were studied with HRM since 2009. We reviewed the reports, and selected 5 swallowing plots suitable for analysis in each report, analyzed each individual plot with ManoView. The 5 parameters from each plot in 57 globus patients were compared with that of 24 GERD patients and 7 normal controls. There was no significant difference in the UES pressure, CFV, PCI and DCI. TZ (using 30 mmHg isobaric contour) in globus showed significant difference compared with normal controls and GERD patients. The median values of TZ were 4.26 cm (interquartile range [IQR], 2.30-5.85) in globus patients, 5.91 cm (IQR, 3.97-7.62) in GERD patients and 2.26 cm (IQR, 1.22-2.92) in normal controls (P = 0.001). HRM analysis suggested that UES pressure, CFV, PCI and DCI were not associated with globus. Instead increased length of TZ may be correlated with globus. Further study comparing HRM results in globus patients within larger population needs to confirm their correlation.

Exposure to excess gastric acid resulting from gastroesophageal reflux disease, also known as acid reflux or heartburn, might contribute to initiation of head and neck squamous cell carcinoma, particularly laryngeal cancer. Prior epidemiologic studies have reported inconsistent results. We sought to clarify this relationship using an observational study with a larger available sample size and better-characterized exposure information than most prior studies. A population-based case-control study of head and neck cancer in North Carolina with 1,340 newly diagnosed cases and 1,378 controls matched on age, race, and sex. We used unconditional logistic regression to examine associations between self-reported heartburn and development of overall head and neck cancer as well as development of cancer at specific tumor sites. Subgroup analysis by smoking and alcoholic drinking status was used to make comparisons with a previous study that used a similar study design. Overall, an increased odds of head and neck cancer was not associated with either self-reported history of heartburn symptoms (odds ratio = 0.85; 95% confidence interval 0.68, 1.06) or self-reported medical diagnosis of GERD (OR = 0.89; 95% CI 0.71, 1.11). These patterns held for specific tumor sites. For laryngopharyngeal cancer, we did not detect any associations regardless of joint smoking and alcoholic drinking status. Gastroesophageal reflux does not appear to play a role in development of head and neck cancer. 3b.

Increased salivary pepsin could indicate an increase in gastro-esophageal reflux, however, previous studies failed to demonstrate a correlation between salivary pepsin concentrations and 24-hour esophageal acid exposure. This study aims to detect the salivary pepsin and to evaluate the relationship between salivary pepsin concentrations and intercellular spaces (IS) in different gastroesophageal reflux disease phenotypes in patients. A total of 45 patients and 11 healthy volunteers were included in this study. All subjects underwent upper gastrointestinal endoscopy, 24-hour ambulatory multichannel impedance-pH (MII-pH) monitoring, and salivary sampling at 3-time points during the 24-hour MII-pH monitoring. IS were measured by transmission electron microscopy, and salivary pepsin concentrations were determined by enzyme-linked immunosorbent assay. The IS measurements were greater in the esophagitis (EE), non-erosive reflux disease (NERD), and hypersensitive esophagus (HO) groups than in the functional heartburn (FH) and healthy volunteer groups, and significant differences were indicated. Patients with NERD and HO had higher average pepsin concentrations compared with FH patients. A weak correlation was determined between IS and salivary pepsin among patients with NERD ( r = 0.669, P = 0.035). We confirmed the presence of a higher level of salivary pepsin in patients with NERD than in patients with FH. Salivary pepsin concentrations correlated with severity of mucosal integrity impairment in the NERD group. We suggest that in patients with NERD, low levels of salivary pepsin can help identify patients with FH, in addition the higher the pepsin concentration, the more likely the severity of dilated IS.

A 58-year-old female with a recurrent history of upper abdominal pain and intermittent dysphagia underwent endoscopic evaluation that demonstrated an irregular and nodular esophago-gastric (EG) junction and grade I erosive esophagitis. Biopsies showed prominent intestinal metaplasia of Barrett's type without dysplasia, chronic inflammation and multiple aggregates of large cells within the mucosal lamina propria, some with spindle shaped nuclei. Immunohistochemistry stains for keratins AE-1/AE-3 were negative, while S-100 and NSE were positive. This, together with routine stains, was diagnostic for mucosal ganglioneuromatosis. The background of chronic inflammation with intestinal type metaplasia was consistent with long-term reflux esophagitis. No evidence of achalasia was seen. Biopsies of gastric antrum and fundus were unremarkable, without ganglioneural proliferation. Colonoscopy was unremarkable. No genetic syndromes were identified in the patient including familial adenomatous polyposis and multiple endocrine neoplasia type IIb (MEN IIb). Iansoprazole (Prevacid) was started by oral administration each day with partial relief of symptoms. Subsequent esophagogastroscopy repeated at 4 mo showed normal appearing EG junction. Esophageal manometry revealed a mild non-specific lower esophageal motility disorder. Mild motor dysfunction is seen with gastro-esophageal reflux disease (GERD) and we feel that the demonstration of localized ganglioneuromatosis was not likely related etiologically. In the absence of findings that might suggest neural hypertrophy, such as achalasia, the nodular mucosal irregularity seen with this instance of ganglioneuromatosis may, however, have exacerbated the patient's reflux.

Clinical and pH-metric outcomes of transoral esophagogastric fundoplication for the treatment of gastroesophageal reflux disease.

Transoral treatment of gastroesophageal reflux disease (GERD) using the EsophyX device enables creation of an esophagogastric fundoplication with potential for better control of reflux than gastrogastric techniques. Efficacy and safety of a rotational/longitudinal esophagogastric transoral incisionless fundoplication (TIF) was evaluated retrospectively using subjective and objective outcomes. Thirty-seven consecutive patients on antisecretory medication and with proven gastroesophageal reflux and limited hiatal hernia underwent TIF for persistent GERD symptoms. Five patients were reoperations for failed laparoscopic fundoplication. Of the 37 treated patients, 57% were female. The median age was 58 (range=20-81) years and BMI was 25.5 (range=15.9-36.1) kg/m2. Sixty-eight percent indicated GERD-associated cough, asthma, or aspiration as a primary complaint and 32% complained of heartburn or regurgitation. The TIF procedures created tight wraps of 230°-330° extending 3-4 cm above the Z-line. Two complications occurred: one mediastinal abscess treated laparoscopically and one postoperative bleeding requiring transfusion. At 6 (range=3-14) months median follow-up TIF resulted in a significant improvement of both atypical and typical symptoms in 64% and 70-80% of patients, respectively, as indicated by the corresponding GERD health-related quality of life (HRQL) and reflux symptom index (RSI) score reduction by 50% or more compared to baseline on proton pump inhibitors (PPIs). No patient reported problems with dysphagia, bloating, or excess flatulence, and 82% were not taking any PPIs. Reflux characteristics were significantly improved and normalized in 61, 89, and 56% of patients in terms of acid exposure, number of refluxates, and DeMeester scores, respectively. TIF was effective in treating GERD in 75% of patients among whom 54% were in a complete "remission" and 21% were "improved." The remaining 25% were considered failures, and five (13.5%) patients underwent

The γ-aminobutyric acid type B-receptor agonist lesogaberan (AZD3355) has been developed for use in patients with gastroesophageal reflux disease (GERD) symptoms despite proton pump inhibitor (PPI) therapy (partial responders). This study aimed to explore the dose-response effect of lesogaberan on reflux episodes in partial responders. In this randomized, single-centre, double-blind, crossover, placebo-controlled study, partial responders taking optimised PPI therapy were given 30, 90, 120 and 240 mg doses of lesogaberan. Each dose was given twice (12 h apart) during a 24-h period, during which impedance-pH measurements were taken. Twenty-five patients were included in the efficacy analysis and 27 in the safety analysis. The effect of lesogaberan on the mean number of reflux episodes was dose-dependent, and all doses significantly reduced the mean number of reflux episodes relative to placebo. Lesogaberan also dose-dependently reduced the mean number of acid reflux episodes (except the 30 mg dose) and weakly acid reflux episodes (all doses) significantly, relative to placebo. Regardless of dose, lesogaberan had a similar effect on the percentage of time with esophageal pH < 4 [mean reduction: 68.5% (30 mg), 54.2% (90 mg), 65.9% (120 mg), 72.1% (240 mg); p < 0.05 except 90 mg dose]. No adverse events led to discontinuation and no serious adverse events occurred during active treatment. Lesogaberan inhibited reflux in a dose-dependent manner in partial responders taking optimised PPI therapy, and these effects were significant versus placebo. All lesogaberan doses were well tolerated and were not associated with clinically relevant adverse events. ClinicalTrials.gov identifier: NCT01043185.

Gastroesophageal reflux disease in COPD: links and risks.

2015-01-01

COPD is a long-term condition associated with considerable disability with a clinical course characterized by episodes of worsening respiratory signs and symptoms associated with exacerbations. Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal conditions in the general population and has emerged as a comorbidity of COPD. GERD may be diagnosed by both symptomatic approaches (including both typical and atypical symptoms) and objective measurements. Based on a mix of diagnostic approaches, the prevalence of GERD in COPD ranges from 17% to 78%. Although GERD is usually confined to the lower esophagus in some individuals, it may be associated with pulmonary microaspiration of gastric contents. Possible mechanisms that may contribute to GERD in COPD originate from gastroesophageal dysfunction, including altered pressure in the lower esophageal sphincter (which normally protect against GERD) and changes in esophageal motility. Proposed respiratory contributions to the development of GERD include respiratory medications that may alter esophageal sphincter tone and changes in respiratory mechanics, with increased lung hyperinflation compromising the antireflux barrier. Although the specific cause and effect relationship between GERD and COPD has not been fully elucidated, GERD may influence lung disease severity and has been identified as a significant predictor of acute exacerbations of COPD. Further clinical effects could include a poorer health-related quality of life and an increased cost in health care, although these factors require further clarification. There are both medical and surgical options available for the treatment of GERD in COPD and while extensive studies in this population have not been undertaken, this comorbidity may be amenable to treatment.

Laparoscopic sleeve gastrectomy (LSG) has gained popularity as a treatment of choice for morbid obesity and associated comorbidities. There has been a concern about new onset or worsening of gastroesophageal reflux (GERD) following LSG. The objective of the study was to evaluate the effect of surgically treating hiatal weakness on GERD symptoms in patients undergoing LSG. Single tertiary referral institution, Sydney, Australia. A prospective observational cohort study was conducted with consecutive patients undergoing LSG. Hiatal findings, patient demographics, medications and reflux score were recorded prospectively. Patients were followed up post-operatively for a minimum of 12 months and assessed using GERD-HRQL score to quantify reflux symptoms. Data from 100 patients with a minimum of 1-year follow-up were analysed. Mean follow-up was 18.9 months. Overall, GERD-HRQL improved from mean 4.5 ± 5.8 pre-operatively to 0.76 ± 1.5 after 18.9 months (p = 0.0001). For those with pre-operative reflux, GERD-HRQL improved from mean (SD) 8.43 ± 6.26 pre-operatively to 0.94 ± 1.55 (p = 0.0001). All the nine patients with troublesome daily reflux significantly improved. For those without pre-operative reflux, GERD-HRQL improved from 0.88 ± 1.37 to 0.47 ± 1.25 (p-ns) post-operatively. On multivariate analysis, higher pre-operative reflux and dysphagia/bloat scores, younger age and lower percentage excess weight loss after 18.9 months were associated with GERD-HRQL improvement. In the medium term, GERD-HRQL improves following sleeve gastrectomy with meticulous hiatal assessment and repair of hiatal laxity and herniation.

Numerous case-control and other studies involving confirmation of gastroesophageal reflux disease (GERD) by esophageal pH-metry and the assessment of dental erosions have shown significant associations between the two conditions in both adults and children. By contrast, when asked to vote on whether GERD may cause dental erosions, only 42% of physicians strongly agreed that such an association existed in adults, and just 12.5% strongly agreed for children, respectively in two global consensus reports. Part of this divergence between the perceptions of physicians and the findings of research publications may reflect a general lack of oral health education during medical training, and cursory oral examinations being made under less-than-ideal conditions. Adequate salivary secretions are essential for the protection of the teeth and the oropharyngeal and esophageal mucosa. The quantity and quality of the saliva require monitoring as many drugs, including several of the proton pump inhibitors (PPIs), can cause hyposalivation. In addition, PPIs do not always result in adequate acid suppression. Therefore, collaboration between physicians and dentists is strongly advocated to prevent or ameliorate possible adverse oral effects from both endogenous and exogenous acids, and to promote adequate saliva production in patients with GERD. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

The spectrum of motor function abnormalities in gastroesophageal reflux disease and Barrett's esophagus.

PubMed

Ang, D; Blondeau, K; Sifrim, D; Tack, J

2009-01-01

Barrett's esophagus has traditionally been regarded as the most severe end of the spectrum of gastroesophageal reflux disease and is of great clinical importance in view of the association with esophageal adenocarcinoma. Studies have documented high levels of esophageal acid exposure in Barrett's esophagus. Various pathogenetic mechanisms underlie this phenomenon. These include abnormalities in esophageal peristalsis, defective lower esophageal sphincter pressures, gastric dysmotility and bile reflux. Whilst these factors provide evidence for an acquired cause of Barrett's esophagus, an underlying genetic predisposition cannot be ruled out. Although the past decade has brought about many new discoveries in the pathogenesis of Barrett's esophagus, it has also added further controversy to this complex disorder. A detailed analysis of the gastrointestinal motor abnormalities occurring in Barrett's esophagus follows, with a review of the currently available literature and an update on this condition that continues to be of interest to the gastroenterologist.

Gastroesophageal reflux symptoms not responding to proton pump inhibitor: GERD, NERD, NARD, esophageal hypersensitivity or dyspepsia?

PubMed Central

Bashashati, Mohammad; Hejazi, Reza A; Andrews, Christopher N; Storr, Martin A

2014-01-01

Gastroesophageal reflux (GER) is a common gastrointestinal process that can generate symptoms of heartburn and chest pain. Proton pump inhibitors (PPIs) are the gold standard for the treatment of GER; however, a substantial group of GER patients fail to respond to PPIs. In the past, it was believed that acid reflux into the esophagus causes all, or at least the majority, of symptoms attributed to GER, with both erosive esophagitis and nonerosive outcomes. However, with modern testing techniques it has been shown that, in addition to acid reflux, the reflux of nonacid gastric and duodenal contents into the esophagus may also induce GER symptoms. It remains unknown how weakly acidic or alkaline refluxate with a pH similar to a normal diet induces GER symptoms. Esophageal hypersensitivity or functional dyspepsia with superimposed heartburn may be other mechanisms of symptom generation, often completely unrelated to GER. Detailed studies investigating the pathophysiology of esophageal hypersensitivity are not conclusive, and definitions of the various disease states may overlap and are often confusing. The authors aim to clarify the pathophysiology, definition, diagnostic techniques and medical treatment of patients with heartburn symptoms who fail PPI therapy. PMID:24719900

The aim of the present study was to investigate acid sensitivity in patients with erosive and nonerosive reflux disease and control subjects to determine the relation with functional esophageal mucosal integrity changes as well as to investigate cellular mechanisms of impaired mucosal integrity in these patients. In this prospective experimental study, 12 patients with nonerosive reflux disease, 12 patients with esophagitis grade A or B, and 11 healthy control subjects underwent an acid perfusion test and upper endoscopy. Mucosal integrity was measured during endoscopy by electrical tissue impedance spectroscopy and biopsy specimens were analyzed in Ussing chambers for transepithelial electrical resistance, transepithelial permeability and gene expression of tight junction proteins and filaggrin. Patients with nonerosive reflux disease and esophagitis were more sensitive to acid perfusion compared with control subjects, having a shorter time to perception of heartburn and higher perceived intensity of heartburn. In reflux patients, enhanced acid sensitivity was associated with impairment of in vivo and vitro esophageal mucosal integrity. Mucosal integrity was significantly impaired in patients with esophagitis, displaying higher transepithelial permeability and lower extracellular impedance. Although no significant differences in the expression of tight junction proteins were found in biopsies among patient groups, mucosal integrity parameters in reflux patients correlated negatively with the expression of filaggrin. In conclusion, sensitivity to acid is enhanced in patients with gastroesophageal reflux disease, irrespective of the presence of erosions, and is associated with impaired esophageal mucosal integrity.

Gastroesophageal reflux disease (GERD) is a chronic disease characterized by symptoms of heartburn and acid regurgitation. Uncontrolled GERD can significantly impact quality of life, can lead to complications, and increases the risk of esophageal cancer. Over the past few decades, there has been an increasing prevalence of GERD among adults in Western populations. The use of proton pump inhibitors (PPI) in conjunction with lifestyle modifications remains the mainstay therapy. However, the efficacy of this intervention is often hampered by adherence, costs, and the risks of long-term PPI use. Anti-reflux surgery is an option for patients with refractory symptoms or in those in whom medical therapy is contraindicated or not desirable. While conventional surgery has an acceptable safety profile, there has been an increasing interest in alternate treatments that may potentially offer similar results and be associated with a faster recovery. Recent advances in interventional endoluminal techniques have introduced novel incisionless anti-reflux procedures. While the current data are promising, further larger prospective studies are needed in order to assess the long-term efficacy of endoluminal therapies and its place among the treatment options for GERD.

Gastroesophageal reflux disease (GERD) is a common functional gastrointestinal disorder with significant effects on the quality of life. The burden of GERD is soaring in Asia. Preventing symptom relapse is a therapeutic goal in GERD patients. Since proton pump inhibitors (PPI) are the first-line treatment of GERD, drug failure has become a major problem in the treatment procedure. We reviewed the literature in order to find articles related to comorbidities and symptoms affecting GERD from 1980 to 2015 via PubMed and Google Scholar using keywords such as ‘Gastroesophageal reflux disease’, ‘Gastrointestinal symptoms’ and Boolean operators (such as AND, OR, NOT). Due to the cost of PPI therapy and the high rate of GERD relapse after PPI therapy, demand for continuing this type of treatment is decreasing. Thus, we need to discover new approaches to treat the disease and also investigate the relationship between the treatment of GERD and its comorbidities and symptoms such as functional constipation.

Background Refractory gastroesophageal reflux disease (GERD) may deteriorate patient quality of life (QOL) despite proton pump inhibitor (PPI) therapy. Material/Methods Nineteen Japanese institutions were surveyed to determine the clinical characteristics and QOL of patients with refractory GERD. Those patients treated with a conventional PPI were switched to 20 mg esomeprazole for 4 weeks. Symptoms and QOL were assessed using Global Overall Symptom and Gastrointestinal Symptom Rating Scale (GSRS) questionnaires at baseline and at 2 and/or 4 weeks of esomeprazole treatment. Results Of 120 patients who completed the survey, 58 (48.3%) had refractory GERD. Of these, 69.0% were aged ≥65 years, 79.3% were prescribed a PPI at a standard or high dose, and 22.4% were prescribed a PPI together with another drug. After switching to esomeprazole, patients reported significant improvements in heartburn, acid regurgitation, and excessive belching at 2 weeks using a symptom diary, as well as the total score, reflux, abdominal pain, and indigestion, which were assessed using the GSRS at 4 weeks. Conclusions About half of Japanese patients with GERD may be refractory to conventional PPIs. Their reflux-related symptoms are often severe and may impair QOL. Switching to esomeprazole could be used to improve their symptoms and QOL. PMID:26719012

Management of gastroesophageal reflux disease.

PubMed

Tutuian, Radu; Castell, Donald O

Gastroesophageal reflux disease (GERD) is a chronic condition requiring long-term treatment. Simple lifestyle modifications are the first methods employed by patients and, because of their low cost and simplicity, should be continued even when more potent therapies are initiated. Potent acid-suppressive therapy is currently the most important and successful medical therapy. Whereas healing of the esophageal mucosa is achieved with a single dose of any proton pump inhibitor (PPI) in more than 80% of cases, symptoms are more difficult to control. Patients with persistent symptoms on therapy should be tested (preferably with combined multichannel intraluminal impedance and pH) for association of symptoms with acid, nonacid, or no GER. Long-term follow-up studies indicate that PPIs are efficacious, tolerable, and safe medication. So far, promotility agents have shown limited efficacy, and their side-effect profile outweighs their benefits. Antireflux surgery in carefully selected patients (ie, young, typical GERD symptoms, abnormal pH study, and good response to PPI) is as effective as PPI therapy and should be offered to these patients as an alternative to medication. Still, patients should be informed about the risks of antireflux surgery (ie, risk of postoperative dysphagia; decreased ability to belch, possibly leading to bloating; increased flatulence). Endoscopic antireflux procedures are recommended only in selected patients and given the relative short experience with these techniques, patients treated with endoscopic procedures should be enrolled in a rigorous follow-up program.

A causal relationship between cough and gastroesophageal reflux disease (GERD) has been established: a pro/con debate.

Along with upper airway cough syndrome (formerly, postnasal drip syndrome) and eosinophilic airway inflammation (asthma, nonasthmatic eosinophilic bronchitis), gastroesophageal reflux disease (GERD) is generally considered among the most common etiologies of chronic cough. Indeed, cough management guidelines published by numerous respiratory societies worldwide recommend evaluation and treatment of GERD as an integral component of the diagnostic/therapeutic algorithm for the management of chronic cough. However, a significant number of patients with chronic cough presumed due to GERD do not report improvement despite aggressive acid-suppressive therapy. Some of these refractory cases may be due to the recently appreciated entity of nonacid or weakly acidic reflux. Further contributing to the controversy are recent studies that demonstrate that patients with chronic cough do not have excessive reflux events relative to healthy volunteers. Although a temporal relationship between cough and reflux events has been suggested by studies utilizing impedance-pH monitoring of reflux events and objective cough recording, consensus is lacking in terms of whether this temporal relationship proves a causal link between reflux and cough. The fourth American Cough Conference (New York, June 2013) provided an ideal forum for the debate of this issue between two internationally recognized experts in the field of reflux and chronic cough.

Barrett esophagus (BE) is defined as a columnar metaplasia of the distal esophagus that develops as a result of chronic gastroesophageal reflux disease (GERD). A distinctive type of multilayered epithelium (ME) that exhibits features of both squamous and columnar epithelium has been hypothesized to represent an early, or intermediate, phase in the development of BE. The aim of this prospective study was to evaluate the prevalence and specificity of ME in mucosal biopsies of the squamocolumnar junction (SCJ) from patients who had GERD, either with or without BE. During endoscopic examination of the esophagus, 2 biopsy specimens were obtained from across the SCJ from 27 patients with BE, 12 patients who had GERD without BE, and 14 controls who had no symptoms or endoscopic or histologic signs of GERD. ME was present at the SCJ in 33%, 33%, and 0% of BE, GERD, and control patients, respectively. Compared with control subjects, the prevalence of ME was significantly higher in both GERD and BE patients (P<0.05). In GERD patients without BE, ME was always detected adjacent to areas of cardia-type mucosa composed of mucous glands. ME from GERD patients and BE patients had a similar immunophenotype, showing expression of the intestinal markers MUC2 and cdx-2 in 38% and 77% of cases, respectively. The prevalence of expression of these markers in ME was significantly different from nongoblet epithelium in control patients. Our results provide further evidence that ME may represent an early, transitional form of columnar metaplasia, and that ME may be used as a histologic marker of reflux disease in mucosal biopsies from the gastroesophageal junction region.

Gastroesophageal reflux disease (GERD) is a very common condition whose consequences of are localized not only in the esophagus; extra-esophageal involvement has frequently been reported. The aim of the study is to examine the incidence and pattern of dental erosion in GERD patients. A total of 50 patients were recruited in this study (control -25 and GERD -25). All participants diagnosed having GERD by the endoscopic examination by their gastroenterologist are included. The patients were examined for dental erosion and will be quantified using Basic erosive wear examination index. The results showed that the incidence of dental erosion was 88% as compared to 32% in the control group which was found to be statistically significant.

Objective To determine whether anti-reflux medications reduce bradycardia episodes attributed to clinically suspected gastroesophageal reflux (GER). Study design We conducted a masked trial comparing metoclopramide, 0.2 mg/kg/dose q 6 hours, and ranitidine, 2 mg/kg/dose q 8 hours, with saline placebo. Each infant served as his own control. Preterm infants having >3 bradycardia episodes per 2 days were eligible if the clinician intended to begin anti-reflux medications for bradycardia attributed to GER. Results The mean (SD) birth weight was 1238 (394) g and gestational age was 29 (3) weeks. Eighteen infants were enrolled at 35 (22) days of age. There were 4.6 (3.1) and 3.6 (2.7) bradycardia episodes per day in the drug and placebo periods, respectively. The mean difference (drug minus placebo) was 0.94 (95% CI, 0.04 to 1.95) (P = .04 by t test). There was a decrease in bradycardia episodes over time (P < .001 by nonparametric repeated-measures analysis of variance). Conclusions Anti-reflux medications did not reduce, and may have increased, bradycardia episodes in preterm infants with GER. Because there was an improvement of bradycardia episodes over time, unrelated to treatment, unmasked therapeutic trials of medications are likely to lead to misleading conclusions. PMID:19540518

Gastroesophageal reflux disease (GERD) and psychological stress are associated with sleep disturbances. The aim of the present study was to examine the prevalence of sleep disturbances, anxiety, and depression by GERD subtypes and to identify factors associated with sleep disturbances in general population. A total of 2002 Japanese subjects, who underwent annual health checkups, were enrolled and asked to fill out a questionnaire, including the frequency scale for the symptoms of GERD (FSSG), Athens Insomnia Scale (AIS), Rome III questionnaire, and Hospital Anxiety and Depression Scale (HADS). GERD was divided into asymptomatic erosive reflux disease (a-ERD), symptomatic ERD (s-ERD), and non-erosive reflux disease (NERD), according to the presence or absence of esophageal mucosal injury on endoscopy, and the FSSG scores. Sleep disturbances were diagnosed in subjects with AIS score ≥6. Prevalence of sleep disturbances was significantly higher in GERD subjects than in controls (35.9 and 14.7%, respectively), especially, in the NERD group (45.1%). Sleep duration was significantly shorter in the s-ERD group compared with other groups. Subjects in the NERD and s-ERD groups showed higher HADS scores, resulting in higher incidences of anxiety and depression than those in the control and a-ERD groups. Reflux symptoms, anxiety, depression, and coexisting functional dyspepsia, but not the presence of esophageal mucosal injury, were associated with an increased odds ratio for sleep disturbances. There were significant positive associations among reflux symptoms, psychological stress, and sleep disturbance in Japanese adults. Further studies investigating the efficacy of therapy are needed.

To study the clinical curative effect, safety and mechanism of action of electroacupuncture combined with Zhizhukuanzhong capsules (ZZKZC) in treating gastroesophageal reflux disease (GERD). A total of 480 patients with confirmed GERD were randomly divided into four groups: the electroacupuncture group, the ZZKZC group, the combined therapy group, and the control group, with 120 cases in each group. Each case in the electroacupuncture group was treated with electroacupuncture on Zusanli (ST 36), Zhongwan (CV 12), Neiguan (PC 6),Taichong (LR 3) and Gongsun (SP 4) once daily for 6 weeks. Each case in the ZZKZC group was treated with oral administration of 1.29 g ZZKZC three times daily. The combined therapy group had electroacupuncture and ZZKZC. The control group was given oral administration of 5 mg mosapride three times and 20 mg pantoprazole twice daily. The 24-hour intraesophageal total number of reflux episodes with pH <4 (or bilirubin absorbance > or = 0.14), the number of long-term (> or = 5 min) reflux episodes, the percentage of upright time, the percentage of supine time, the percentage of total time of pH <4 (or bilirubin absorbance > or = 0.14), endoscopic grading score, symptom score, quality of life score, and adverse reactions were observed before treatment, at the end of treatment and 54 weeks after treatment in the four groups. The 24-hour intraesophageal pH and bile reflux, endoscopic grading score and symptom score were all significantly decreased at the end of treatment in every group, while the scores of 8 dimensions of quality of life were all increased compared with those before treatment (P<0.01). All of these indices were better in the combined therapy group than those in the other groups (P<0.05). These indices did not significantly deteriorate in the combined therapy group and electroacupuncture group 54 weeks after treatment compared with the end of treatment (P>0.05); however, these indices all significantly deteriorated in the ZZKZC and

This article reviews the sex differences in upper gastrointestinal (GI) motility for both healthy and common dysmotility conditions. It focuses on gastroesophageal reflux disease and other esophageal motor disorders for the esophagus and on gastroparesis and accelerated gastric emptying for the stomach. It also describes differences in upper GI motility signs and symptoms during each female hormonal stage (ie, menstrual cycle, pregnancy, perimenopause, menopause) for both healthy participants and those suffering from one of the aforementioned upper GI dysmotility conditions. More research still needs to be conducted to better understand sex differences in upper GI motility. Copyright © 2016 Elsevier Inc. All rights reserved.

Gastroesophageal reflux disease (GERD) is associated with allograft dysfunction after lung transplantation (LTX). We attempted to identify outcomes in LTX recipients with clinical evidence of GERD. Retrospective review of 162 LTX recipients at our institution between January 1994 and June 2006 was performed. GERD was confirmed in symptomatic patients by esophagogastroduodenoscopy (EGD) and/or esophagography. Occurrence of biopsy-proven obliterative bronchiolitis (OB) and bronchiolitis obliterans syndrome (BOS) were analyzed. Kaplan-Meier analysis of survival and Cox proportional hazard analysis of risk factors were performed. GERD was diagnosed in 21 (13%) of patients, usually following LTX (71%). There was no difference in mean survival (1603 +/- 300 vs. 1422 +/- 131 days; log rank P > 0.05), or development of OB (5% vs. 6%, respectively; P > 0.05) in patients with GERD compared with patients without GERD. However, there was correlation between GERD and BOS (P = 0.01). Symptomatic GERD is increased following LTX. Patients with symptomatic GERD demonstrated an increased incidence of BOS, but survival was not affected in this study. More sensitive and specific diagnostic tools should be implemented in all LTX recipients to investigate the impact of symptomatic and silent GERD and thus improve outcomes after LTX.

Laryngopharyngeal reflux is defined as the reflux of gastric content into larynx and pharynx. A large number of data suggest the growing prevalence of laryngopharyngeal symptoms in patients with gastroesophageal reflux disease. However, laryngopharyngeal reflux is a multifactorial syndrome and gastroesophageal reflux disease is not the only cause involved in its pathogenesis. Current critical issues in diagnosing laryngopharyngeal reflux are many nonspecific laryngeal symptoms and signs, and poor sensitivity and specificity of all currently available diagnostic tests. Although it is a pragmatic clinical strategy to start with empiric trials of proton pump inhibitors, many patients with suspected laryngopharyngeal reflux have persistent symptoms despite maximal acid suppression therapy. Overall, there are scant conflicting results to assess the effect of reflux treatments (including dietary and lifestyle modification, medical treatment, antireflux surgery) on laryngopharyngeal reflux. The present review is aimed at critically discussing the current treatment options in patients with laryngopharyngeal reflux, and provides a perspective on the development of new therapies.

Background Overweight and obese individuals are at increased risk for gastroesophageal reflux disease (GERD). An association between body mass index (BMI) and GERD symptoms among normal weight individuals has not been demonstrated. Methods In 2000, a supplemental questionnaire was used to determine the frequency, severity, and duration of GERD symptoms among randomly-selected participants of the Nurses’ Health Study. After categorizing women by BMI as measured in 1998, we used logistic regression models to study the association between BMI and GERD symptoms. Results Among 10,545 women who completed the questionnaire (86% response rate), 2,310 (22%) reported experiencing symptoms at least once a week (55% of whom described their symptoms as moderate in severity). We observed a dose-dependent relationship between increasing BMI and frequent reflux symptoms (multivariate P for trend <0.001). Compared to women with BMI 20–22.49 kg/m2, the multivariate odds ratios (ORs) were 1.38 (95% CI 1.13–1.67) for BMI 22.5–24.9; 2.20 (95% CI 1.81–2.66) for BMI 25–27.4; 2.43 (95% CI 1.96–3.01) for BMI 27.5–29.9; 2.92 (95% CI 2.35–3.62) for BMI 30–34.9, 2.93 (95% CI 2.24–3.85) for BMI ≥35, and 0.67 (95% CI 0.48–0.93) for BMI <20. Even among women with normal baseline BMI, weight gain between 1984 and 1998 was associated with increased risk of frequent reflux symptoms (OR 2.8 (95% CI 1.63–4.82) for BMI increase >3.5). Conclusion BMI is associated with GERD symptoms in both normal weight and overweight individuals. Our findings suggest that even modest weight gain among normal weight individuals may cause or exacerbate reflux symptoms. PMID:16738270

The purpose is to evaluate the effectiveness of itopride (IP) and domperidone (DP) in the treatment of patients with gastroesophageal reflux disease (GERD), in combination with diabetes mellitus (DM) type 1 and 2. 40 patients were examined with GERD and type 1 diabetes and 50 patients with GERD and type 2 diabetes. Each group of patients with GERD, DM 1 and 2 has been divided into: the basic subgroup receiving IG 50 mg 3 tid and control--DP 10 mg tid. Patients were also administered omeprazole. Both subgroups were strictly randomized to key indicators, except for therapy. Baseline and after 2 and 4 weeks, all patients were examined to identify complaints, endoscopy and pH-metric changes, gastric motility was studied by electrogastroenterographic method (PEGEG). In the subgroups of patients with GERD + DM 1 and GERD + DM 2, received treatment with IG complaints on heartburn, regurgitation, odynophagia relieved significantly earlier then in the subgroups treated with DP. After 4 weeks of therapy, decreasing in the number of gastroesophageal refluxes, number of patients with erosive esophagitis B level, and normalization of the motility of the stomach were significantly higher in the groups of GERD + DM 1 and GERD + DM 2 received treatment with IG when compared with the subgroup of PD. There were no side effects of prokinetics. IG was more effective then DP in the treatment of GERD in patients with diabetes, and may be recommended for inclusion in the scheme of treatment of this comorbidity.

Gastroesophageal reflux disease (GERD) is a chronic disease with a negative impact on the quality of life. The aim of this study was to investigate the reflux symptoms and the health-related quality of life in a population with GERD. Data from patients with GERD, according to the Montreal definition, were collected between January and December 2009. The enrolled patients were classified by different reflux symptoms according to the modified Chinese GERDQ. The general demographic data, the modified GERD impact scores and the SF-36 questionnaire scores of these groups of patients were analyzed. A total of 173 patients were enrolled, and the general data, endoscopic findings and lifestyle habits of the participants with different severity of heartburn or regurgitation were all similar. The patients with moderate severity of reflux symptoms had significant lower SF-36 scores than those with mild severity. The cases with advanced heartburn severity owned the lowest scores among all cases. The impact on the daily activity of each affected individual had a positive association with the stronger severity of reflux symptom. The life quality of a population with GERD achieved the meaningful declination in participants with the moderate severity of heartburn or regurgitation. The severity of the reflux symptoms had a greater impact on the normal daily activity of the patients with GERD. The cases with advanced severity of heartburn had the worst well-being.

This study aims to evaluate the upper esophageal sphincter (UES) motility in patients with gastroesophageal reflux disease (GERD) as compared to healthy volunteers. We retrospectively studied the HRM tests of 44 patients (median age: 61 years, 54% females) under evaluation for GERD. The manometric UES parameters of these patients were compared to 40 healthy volunteers (median age: 27 years, 50% females). Almost half of the patients had a short and hypotonic UES. Patients with extraesophageal symptoms had a higher proportion of hypotonic UES as compared to patients with esophageal symptoms. Reflux pattern did not influence manometric parameters. Proximal reflux (any number of episodes) was present in 37(84%) patients (median number of proximal episodes = 6). Manometric parameters are similar in the presence or absence of proximal reflux. There is not a correlation between the UES length and UES basal pressure. In conclusion, our results show that: (1) the manometric profile of the UES in patients with GERD is characterized by a short and hypotonic UES in half of the patients; (2) this profile is more pronounced in patients with extraesophageal symptoms; and (3) neither the presence of proximal reflux nor reflux pattern bring a different manometric profile. © The Authors 2017.

2017-11-22

The anatomy of esophagogastric junction (EGJ) serves as the anti-reflux barrier. The gastroesophageal flap valve (GEFV) is a component of EGJ. The aim of the current study was to assess its correlation with the esophageal acid exposure and the impact on anti-reflux barrier function by using the metrics of EGJ contraction. Eighty three patients with typical GERD symptoms were included in the study. Upper endoscopy, high-resolution manometry (HRM) and 24 h multichannel intraluminal impedance-pH (MII-pH) monitoring were performed in all patients. GEFV was determined as four grades during endoscopic examination based on the Hill classification. The esophageal pressure topography (EPT) metrics defined in the updated Chicago Classification were measured by HRM, including integrated relaxation pressure (IRP), EGJ contractile index (EGJ-CI),expiratory EGJ pressure(EGJP-exp) and inspiratory EGJ pressure (EGJP-insp). The GEFV grade III and IV was more commonly found in patients with esophagitits (p < 0.05). The acid exposure time (AET%) and supine AET% were lower in patients with GEFV grade I (p < 0.01). There was weak correlation between AET% and GEFV grades (r = 0.27, p = 0.013). There were more EGJ morphology type III in patients with GEFV grade IV (p < 0.05).There were no significant differences on the values of four HRM metrics among the patients with different GEFV grades (p > 0.05). The GEFV grades were associated with acid reflux positively and could be a good reflection of EGJ morphology in HRM. But it had no impact on the four HRM metrics. Our research revealed that GEFV may play an assistant role in the anti-reflux barrier.

Gastroesophageal reflux disease (GERD) can mimic epileptic seizure, and may be misdiagnosed as epilepsy. On the other hand, GERD can be more commonly seen in children with neurological disorders such as cerebral palsy (CP); this co-incidence may complicate the management of patients by mimicking refractory seizures. The purpose of our study was to evaluate the clinical features, definite diagnoses and treatment approaches of the patients with clinically suspected GERD who were referred to the division of pediatric neurology with a suspected diagnosis of epileptic seizure. We also aimed to investigate the occurrence of GERD in children with epilepsy and/or CP. Fifty-seven children who had a final diagnosis of GERD but were initially suspected of having epileptic seizures were assessed prospectively. All patients were assigned to 3 groups according to definite diagnoses as follows: patients with only GERD who were misdiagnosed as having epileptic seizure (group 1: n=16; 28.1%), those with comorbidity of epilepsy and GERD (group 2: n=21; 36.8%), and those with the coexistence of GERD with epilepsy and CP (group 3: n=20; 35.1%). Five patients (8.8%) did not respond to anti-reflux treatment and laparoscopic reflux surgery was performed. The positive effect of GERD therapy on paroxysmal nonepileptic events was observed in 51/57 (89.5%) patients. GERD is one of the important causes of paroxysmal nonepileptic events. In addition, GERD must be kept in mind at the initial diagnosis and also in the long-term management of patients with neurological disorders such as epilepsy and CP.

Detailed population-based data regarding the prevalence and symptom profile of gastroesophageal reflux disease (GERD) in underdeveloped and developing Caucasian countries are lacking. The aim of this study was to determine the prevalence and clinical spectrum of GERD in a low-income region in Turkey. We used a previously validated reflux questionnaire, which was translated into Turkish and culturally adapted. The questionnaire was applied to 630 randomly selected participants greater than 20 yr old living in a population of 8,857 adults, with a low mean income of 75 dollars/person/month. The reliability and reproducibility of the questionnaire were calculated using the kappa statistic (test-retest). Endoscopy and/or 24-h intraesophageal pH monitoring were used to ascertain its validity in identifying patients with reflux. The prevalence of GERD symptoms was 10% for heartburn, 15.6% for regurgitation, and 20% for either symptom experienced at least weekly (95% CI). Heartburn and regurgitation were associated with noncardiac chest pain (37.3%), dysphagia (35.7%), dyspepsia (42.1%), odynophagia (35.7%), globus, hoarseness, cough, hiccup, nausea, vomiting, belching, and NSAID use, but not with body mass index in both frequent and occasional symptom groups. The prevalence of heartburn symptoms, but not regurgitation, increased significantly with age. The prevalence of GERD in a low-income population in Turkey was similar to that of developed countries, although with a different symptom profile, namely, a lower incidence of heartburn and a higher incidence of regurgitation and dyspepsia. These findings support the contention that there are a large number of patients worldwide in underdeveloped nations with poorly recognized and largely undertreated GERD.

The objective of this study is to evaluate whether the water siphon maneuver improves detection of gastroesophageal (GE) reflux during barium esophagography compared with observation for spontaneous reflux only. Histopathologic analysis is the reference standard. This retrospective study assessed 87 outpatients who underwent both barium esophagography and upper endoscopy-guided biopsy within a 30-day interval. The water siphon maneuver was routinely performed when spontaneous GE reflux was not observed during the fluoroscopic study. Radiology reports were reviewed for mentions of the presence of reflux and the circumstances in which it was observed (as a spontaneous occurrence or as a result of the water siphon maneuver). Pathology reports from subsequent endoscopic biopsies were reviewed to identify histologic changes of reflux disease. The sensitivity, specificity, and accuracy of esophagography, observation for spontaneous reflux, and the water siphon maneuver were calculated and then compared using a McNemar test. Of the 87 patients, 57 (65.5%) had GE reflux diagnosed on the basis of histologic changes noted on endoscopy, and 30 (34.5%) did not. A total of 57 patients (65.5%) showed reflux during esophagography, 41 (71.9%) of whom had reflux diagnosed by the water siphon maneuver, and 16 (28.1%) had reflux diagnosed on the basis of observation of spontaneous reflux. Forty-four patients had reflux diagnosed on the basis of both a barium study and histologic findings; 13 patients had reflux noted on esophagography but had negative histologic findings. The overall sensitivity, specificity, and accuracy of esophagography for reflux were 77.2%, 56.7%, and 70.1%, respectively. Spontaneous reflux alone had a sensitivity, specificity, and accuracy of 21.1%, 86.7%, and 43.7%, respectively. The water siphon maneuver showed a sensitivity of 71.1%, a specificity of 65.4%, and accuracy of 69.0%. The differences in the sensitivity, specificity, and accuracy of the water

This study investigated the effectiveness of diaphragm biofeedback training (DBT) for patients with gastroesophageal reflux disease (GERD). A total of 40 patients with GERD treated at the Peking Union Medical College Hospital between September 2004 and July 2006 were randomized to receive DBT and rabeprazole proton pump inhibitor (PPI) or rabeprazole alone. The DBT + rabeprazole group received DBT during the 8-week initial treatment; the rabeprazole group did not. During the 6-month follow up, all patients took acid suppression according to their reflux symptoms, and the patients in the DBT + rabeprazole group were required to continue DBT. The primary outcome (used for power analysis) was the amount of acid suppression used at 6 months. Secondary outcomes were reflux symptoms, health-related quality of life (HRQL), and esophageal motility differences after the 8-week treatment compared with baseline. Acid suppression usage significantly decreased in the DBT + rabeprazole group compared with the rabeprazole group at 6 months (P < 0.05). At 8 weeks, reflux symptoms and GERD-HRQL were significantly improved in both groups (P < 0.05), without difference between them. Crural diaphragm tension (CDT) and gastroesophageal junction pressure (GEJP) significantly increased in the DBT + rabeprazole group (P < 0.05), but without change in lower esophageal sphincter (LES) pressure. There was no significant change in CDT, GEJP, and LES pressure compared with baseline in the rabeprazole group. In conclusion, long-term DBT could reduce acid suppression usage by enhancing the anti-reflux barrier, providing a non-pharmacological maintenance therapy and reducing medical costs for patients with GERD. © 2015 International Society for Diseases of the Esophagus.

Nocturnal gastroesophageal reflux (nGER) is common among patients with obstructive sleep apnea (OSA). Previous studies demonstrated that continuous positive airway pressure (CPAP) reduces symptoms of nGER. However, improvement in nGER symptoms based on objective CPAP compliance has not been documented. We have examined the polysomnographic characteristics of patients with nGER and OSA and looked for association of OSA severity and CPAP compliance with improvement in nGER symptoms. We interviewed 85 veterans with OSA to assess their daytime sleepiness (Epworth Sleepiness scale [ESS]) and nGER symptom frequency after their polysomnography and polysomnographic data were reviewed. At 6 months' follow-up, ESS score, nGER score, and CPAP machine compliance data were reassessed. Data from 6 subjects were dropped from final analysis due to their initiation of new medication for nGER symptom since the initial evaluation. Sixty-two of 79 (78%) patients complained of nGER symptoms during initial visit. At baseline, nGER score was correlated with sleep efficiency (r = 0.43), and BMI correlated with the severity of OSA (r = 0.41). ESS and nGER improved (p < 0.0001) in all patients after 6 months, but more significantly in CPAP compliant patients. A minimum CPAP compliance of 25% was needed to achieve any benefit in nGER improvement. Nocturnal gastroesophageal reflux is common among patients with OSA which increases sleep disruption and worsens the symptoms of daytime sleepiness. CPAP therapy may help improve the symptoms of both nocturnal acid reflux and daytime sleepiness, but adherence to CPAP is crucial to achieve this benefit. © 2016 American Academy of Sleep Medicine.

None of current diagnostic methods has been proven to be a reliable tool for gastro-esophageal reflux disease (GERD). Pepsin in saliva has been proposed as a promising diagnostic biomarker for gastro-esophageal reflux. We aimed to determine the diagnostic value of salivary pepsin detection for GERD. Two hundred and fifty patients with symptoms suggestive of GERD and 35 asymptomatic healthy volunteers provided saliva on morning waking, after lunch and dinner for pepsin determination using the Peptest lateral flow device. All patients underwent 24-h multichannel intraluminal impedance pH (24-h MII-pH) monitoring and upper gastrointestinal endoscopy. Based on 24-h MII-pH and endoscopy study, patients were defined as GERD (abnormal MII-pH results and/or reflux esophagitis) and non-GERD otherwise. Patients with GERD had a higher prevalence of pepsin in saliva and higher pepsin concentration than patients with non-GERD and healthy controls (P < 0.001 for all). The pepsin test had a sensitivity of 73% and a specificity of 88.3% for diagnosing GERD using the optimal cut-off value of 76 ng/mL. Postprandial saliva samples collected when the symptoms occurred had a more powerful ability to identify GERD. Salivary pepsin test had moderate diagnostic value for GERD. It may be a promising tool to replace the use of currently invasive tools with advantages of non-invasive, easy to perform and cost effective.

Antireflux therapy is incorporated in many treatment protocols for recurrent respiratory papillomatosis (RRP) because gastroesophageal reflux (GERD) is thought to worsen the disease course of RRP. It is unclear if GERD really aggravates the disease course. The aims of this systematic review were to 1) evaluate incidence of GERD among RRP patients and 2) report if GERD changes the clinical course or tissue properties of RRP. A search was conducted in PubMed, Embase, and Google Scholar, following the methods of Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines. Articles with original data, published after January 1, 1990, on RRP with GERD as a determinant were eligible. There was no language restriction. Data on study design, study population, statistics, outcomes (incidence and influence of GERD), and risk of bias were collected and evaluated following PRISMA protocols. Of 1,277 articles, 19 were selected. Gastroesophageal reflux was objectified in 25% to 100% of RRP patients. Subjective GERD was present in 0% to 70% of patients. There is no proof that GERD aggravated the clinical course or tissue properties of RRP, as measured by the number of surgeries, severity scoring systems, or dysplasia. One study did find a higher chance of web formation in patients with anterior or posterior glottic papillomas who did not receive antireflux therapy, but these results should be interpreted with care due to the study's quality. There is insufficient proof that GERD does or does not aggravate the clinical course or tissue properties of RRP.

AIM To determine whether capsaicin infusion could influence heartburn perception and secondary peristalsis in patients with gastroesophageal reflux disease (GERD). METHODS Secondary peristalsis was performed with slow and rapid mid-esophageal injections of air in 10 patients with GERD. In a first protocol, saline and capsaicin-containing red pepper sauce infusions were randomly performed, whereas 2 consecutive sessions of capsaicin-containing red pepper sauce infusions were performed in a second protocol. Tested solutions including 5 mL of red pepper sauce diluted with 15 mL of saline and 20 mL of 0.9% saline were infused into the mid-esophagus via the manometric catheter at a rate of 10 mL/min with a randomized and double-blind fashion. During each study protocol, perception of heartburn, threshold volumes and peristaltic parameters for secondary peristalsis were analyzed and compared between different stimuli. RESULTS Infusion of capsaicin significantly increased heartburn perception in patients with GERD (P < 0.001), whereas repeated capsaicin infusion significantly reduced heartburn perception (P = 0.003). Acute capsaicin infusion decreased threshold volume of secondary peristalsis (P = 0.001) and increased its frequency (P = 0.01) during rapid air injection. The prevalence of GERD patients with successive secondary peristalsis during slow air injection significantly increased after capsaicin infusion (P = 0.001). Repeated capsaicin infusion increased threshold volume of secondary peristalsis (P = 0.002) and reduced the frequency of secondary peristalsis (P = 0.02) during rapid air injection. CONCLUSION Acute esophageal exposure to capsaicin enhances heartburn sensation and promotes secondary peristalsis in gastroesophageal reflux disease, but repetitive capsaicin infusion reverses these effects.

The factors influencing new markers of gastro-esophageal reflux disease detected by impedance-pH monitoring - mean nocturnal baseline impedance (MNBI) and post-reflux swallow-induced peristaltic wave (PSPW) index - need to be evaluated. To compare endoscopy-negative heartburn with chronic autoimmune atrophic gastritis (CAAG). 24 patients with CAAG, 25 with non-erosive reflux disease (NERD) and 25 with functional heartburn (FH) were included. In all patients the main impedance-pH monitoring parameters were calculated. CAAG and NERD patients had a number of reflux events (non-acid ones being more common among the former group) which was higher than that found in FH (p<0.001). MNBI decreased progressively in FH (>3000Ohm), CAAG (>2000Ohm) and NERD (<1000Ohm) patients (p=0.0046). The PSPW index was similar between CAAG and NERD patients but significantly lower in comparison to FH (p<0.0001). Patients with CAAG have evidence of non-acid reflux based on the high number of reflux events and confirmed by low values of MNBI and PSPW index. MNBI is a strong marker of acid/non-acid reflux-induced mucosal damage, whereas the PSPW index can reliably discriminate patients with reflux from those with FH, independently of the acidity of refluxate.

The aim of this study is to compare surface pH in various parts of the oral cavity between patients with gastroesophageal reflux disease (GERD) and healthy controls. Using a flat pH meter sensor, fixed electrode pen type digital pH meter, oral pH levels were assessed at different mucosal sites among 34 GERD patients and 32 healthy controls. Salivary flow rates and buffering capacity were also assessed in them. A thorough oral examination was performed to screen for any oral and dental changes. A significantly lower pH of 6.65 ± 0.13 (mean ± SD) was found in the GERD group compared to control group 7.23 ± 0.12 (p < 0.05). Least pH was found in the floor of the mouth 6.594 ± 0.17 and highest in the lower labial mucosa among the GERD patients. Salivary flow rate and buffering capacity were low in these patients. Significant changes were noticed in the hard and soft tissues of the oral cavity among the GERD group. Oral mucosal pH is altered in GERD patients and may contribute to effects on the oral cavity.

Background/Aims The occurrence of gastroesophageal reflux disease (GERD) is known to be associated with lower post-treatment lower esophageal sphincter pressure in patients with achalasia. This study aimed to elucidate whether GERD after pneumatic balloon dilatation (PD) has a prognostic role and to investigate how the clinical course of GERD is. Methods A total of 79 consecutive patients who were first diagnosed with primary achalasia and underwent PD as an initial treatment were included in this retrospective study. Single PD was performed using a 3.0 cm balloon. The patients were divided into two groups: 1) who developed GERD after PD (GERD group) and 2) who did not develop GERD after PD (non-GERD group). GERD was defined as pathological acid exposure, reflux esophagitis or typical reflux symptoms. Results Twenty one patients (26.6%) developed GERD after PD during follow-up. There were no significant differences between the two groups in demographic or clinical factors including pre- and post-treatment manometric results. All patients in GERD group were well responsive to maintenance proton pump inhibitor therapy including on demand therapy or did not require maintenance. During a median follow-up of 17.8 months (interquartile range, 7.1–42.7 months), achalasia recurred in 15 patients (19.0%). However, the incidence of recurrence did not differ according to the occurrence of GERD after PD. Conclusions GERD often occurs after even a single PD for achalasia. However, GERD after PD is well responsive to PPI therapy. Our data suggest that GERD after PD during follow-up does not appear to have a prognostic role. PMID:24840373

To elucidate the factors associated with residual gastroesophageal reflux disease (GERD) symptoms in patients receiving proton pump inhibitor (PPI) maintenance therapy in clinical practice. The study included 39 GERD patients receiving maintenance PPI therapy. Residual symptoms were assessed using the Frequency Scale for Symptoms of GERD (FSSG) questionnaire and the Gastrointestinal Symptom Rating Scale (GSRS). The relationships between the FSSG score and patient background factors, including the CYP2C19 genotype, were analyzed. The FSSG scores ranged from 1 to 28 points (median score: 7.5 points), and 19 patients (48.7%) had a score of 8 points or more. The patients' GSRS scores were significantly correlated with their FSSG scores (correlation coefficient = 0.47, P < 0.005). In erosive esophagitis patients, the FSSG scores of the CYP2C19 rapid metabolizers (RMs) were significantly higher than the scores of the poor metabolizers and intermediate metabolizers (total scores: 16.7 ± 8.6 vs 7.8 ± 5.4, P < 0.05; acid reflux-related symptom scores: 12 ± 1.9 vs 2.5 ± 0.8, P < 0.005). In contrast, the FSSG scores of the CYP2C19 RMs in the non-erosive reflux disease patients were significantly lower than those of the other patients (total scores: 5.5 ± 1.0 vs 11.8 ± 6.3, P < 0.05; dysmotility symptom-related scores: 1.0 ± 0.4 vs 6.0 ± 0.8, P < 0.01). Approximately half of the GERD patients receiving maintenance PPI therapy had residual symptoms associated with a lower quality of life, and the CYP2C19 genotype appeared to be associated with these residual symptoms.

To determine the frequency, nature, and magnitude of gastroesophageal reflux (GER) in dogs with laryngeal paralysis (LP). Prospective comparative clinical study. Client-owned dogs with LP and healthy client-owned dogs (n = 6 each). Dogs underwent sedated laryngeal examination for diagnosis and grading of bilateral LP and for placement of a nasoesophageal dual pH/impedance probe. Endoscopy was used to confirm probe location and evaluate the distal esophagus. Data were recorded continuously. GER was defined as pH<4 or >7.5 lasting >2 seconds reaching a magnitude of 2 impedance sensors proximally. The median total number of GER events per hour was 0.64 (range, 0.44-1.6) for the LP group and 0.53 (range, 0.38-1.0) for the control group (P = 0.259; power = 0.50). The median total number of alkaline regurgitation events per hour was 0.37 (range, 0.17-0.93) for the LP group and 0.46 (range, 0.25-1.0) for control group (P = 0.575; power = 0.57). The median total number of acidic regurgitation events per hour was 0.22 (range, 0-0.70) and 0.0 (range, 0-0.14) for the LP and control groups, respectively (P = 0.025). Acidic reflux events reached the proximal pH sensor in 2 dogs in the LP group for a total of 4 reflux events and in 1 dog in the control group for a total of 3 reflux events (P = 0.673). Based on the limited number of dogs studied, it appears that dogs with naturally occurring LP have increased acidic reflux events compared to clinically normal dogs. GER can reach the most proximal part of the esophagus. © Copyright 2016 by The American College of Veterinary Surgeons.

The relationship between symptom elimination and normalization of esophageal acid level of gastroesophageal reflux disease (GERD) on proton-pump inhibitor (PPI) therapy has been questioned. This study aimed to evaluate the relationship between symptom response and gastro-esophageal acidity control in Chinese patients with GERD on esomeprazole therapy, and to assess the role of 24-hour esophageal pH-metry after therapy in GERD patients. GERD patients with typical reflux symptoms were enrolled and received esomeprazole 40 mg once daily for 4 weeks. Patients with positive baseline 24-hour esophageal pH-metry were divided into two groups depending on an additional dual-channel 24-hour pH-metry after treatment. The pH- group achieved normalization of esophageal pH level whereas the pH+ group did not. Of the 80 patients studied, 76 had abnormal baseline esophageal pH levels. Of these, 90% (52/58) of symptom-free patients and 67% (12/18) of symptom-persistent patients achieved esophageal pH normalization after therapy (P = 0.030). The mean post-therapy gastric nocturnal percent time of pH < 4.0 was significantly higher in pH+ group than that in pH- group (P < 0.001) after therapy. The multivariate regression analysis identified hiatus hernia (P < 0.001) and persistent reflux symptom (P = 0.004) were two independent factors predicting the low post-therapy esophageal pH level. Symptom elimination is not always accompanied by esophageal pH normalization, and vice verse. Esophageal pH-metry is recommended for GERD patients with hiatus hernia or with persistent reflux symptoms after PPI therapy.

The aim of this study was to determine the effect of gestational age on pharmacokinetics of ranitidine in newborns with gastroesophageal reflux. A prospective, descriptive and pharmacokinetic study was carried out in 30 pre-term and 20 full-term babies. 3 mg/kg of ranitidine was administered intravenously to all the babies and at 0.25, 0.5, 1, 2, 4, and 8 h following the administration, samples of blood were drawn to assess ranitidine levels using high performance liquid chromatographic technique. Pharmacokinetics of ranitidine had a bi-exponential behavior with a half-life elimination of (t1/2el) 2.79 h, area under curve (AUC) of 1688 ng/mL, volume of distribution (Vd) of 1.44 L/kg, and clearance (Cl) of 5.9 L/kg/h. The median plasmatic concentration in pre-terms was 1113 ng/mL and 280 ng/mL in full-terms. Vd, t1/2 and Cl presented high values in preterm although the correlation of Cl with glomerular filtration in term newborns was better. Plasma levels of ranitidine depend on the gestational age of the newborns. However, the possible relationship between after-birth age and pharmacokinetics of the neonates as their internal organs get matured without minding their gestational background.

This study aims to assess the influence of esophagectomy with gastric transposition on the gastroesophageal reflux (GER) and gastric acidity in patients with esophageal cancer. Data on 53 esophageal cancer patients who underwent 24-hour impedance-pH monitoring after esophagectomy were retrospectively analyzed. We used a solid-state esophageal pH probe in which the esophageal pH sensor is placed 1.5 cm distal to the upper esophageal sphincter and the gastric pH sensor is located 15 cm distal to the esophageal pH channel. 24-hour impedance-pH monitoring data and other clinical data including anastomosis site stricture and incidence of pneumonia were collected. We defined pathologic reflux with reference to known normative data. Stricture was defined when an intervention such as bougienage or balloon dilatation was required to relieve dysphagia. The esophageal and gastric mean pH were 5.47 ± 1.51 and 3.33 ± 1.64, respectively. The percent time of acidic pH (<4) was 6.66 ± 12.49% in the esophagus and 70.53 ± 32.19% in the stomach. Esophageal pathologic acid reflux was noticed in 32.1%, 20.8%, and 35.8% during total, upright, and recumbent time, respectively. Esophageal pathologic bolus reflux was noted in 83.0%, 77.4%, and 64.2% during total, upright, and recumbent time, respectively. Gastric acidity increased with time after esophagectomy. Esophageal acid exposure time correlated with intragastric pH. However, esophageal pathologic acid reflux was not associated with anastomosis site stricture or pneumonia. In conclusion, GER frequently occurs after esophagectomy. Thus, strict lifestyle modifications and acid suppression would be necessary in patients following esophagectomy. © The Authors 2017.

There exists a complex interplay between asthma and gastroesophageal reflux disease. Both these diseases are known to aggravate each other and amelioration of one is necessary for the control of the other. There is a paucity of studies in Indian population on this subject. To evaluate the clinical features and the endoscopic findings of the upper gastrointestinal tract in patients with bronchial asthma. Study was conducted at KMC group of hospitals, Mangalore in the Department of chest medicine in association with Department of gastroenterology. Subjects included 50 cases of bronchial asthma and controls were 58 non asthmatic patients with allergic rhinitis and chronic urticaria. All patients were queried about presence or absence of symptoms of upper gastro intestinal tract disorders by gastro oesophageal reflux disease (GERD) questionnaire and all the included patients underwent upper gastro intestinal endoscopy. The study showed that symptoms of gastroesophageal reflux were significantly more in asthmatics (52%) as compared to the controls (28%). The common presenting features of gastroesophageal reflux in asthmatics were heartburn (40%) retrosternal pain (24%), nocturnal cough (18%), dyspepsia (16%) and regurgitation (14%) and the above symptoms were significantly more common in asthmatics as compared to controls. Gastroesophageal reflux disease was found to be significantly more common in the asthmatics (58%) as compared to the control group where it was present in 32.75% of the subjects. Clinical or endoscopic evidence of any upper gastrointestinal disorder was found in 68% of the asthmatics as compared to 37.93% of the controls. This difference was found to be statistically significant. The study showed that gastroesophageal reflux disease was significantly more in asthmatics as compared to the controls. Upper gastrointestinal symptoms were more common in asthmatics as against controls. Clinical or endoscopic evidence of upper gastrointestinal disorder and

The frequency of gastroesophageal reflux disease (GERD) is increasing, in part through easy inspection of the upper digestive tract, but especially for a real spread of the disease as a consequence of modernity, lifestyle, incorrect dietary rules, and stress arising from social norms. It is a common chronic gastrointestinal disorder in Europe and the United States. The aim of our study is to highlight a relationship between gastroesophageal reflux disease and salivary pH as evidenced by indicator strips, especially in the outpatient field. Twenty adult subjects (10 males and 10 females) aged between 18 and 50 years (GROUP A)_ were selected. How to control a homogeneous group of 20 patients without GERD, or from any type of allergies (GROUP B) was enlisted. This method has provided excellent results showing no difference in the measured values compared with the traditional instrumental measurement. Our study has allowed us to observe a strong correlation between the saliva pH, nasal cavities and the interaction between the two districts, and could be the basis for a diagnosis of GERD especially in primary health care clinics and in the initial stage of the disease.

To clarify the effects of rikkunshito on acid reflux, non-acid reflux, and esophageal clearance in patients with gastroesophageal reflux disease (GERD). We enrolled seven patients with vomiting and/or stridor (median 6 years; 1 month-17 years), with a percent total time of esophageal pH <4.0 (reflux index) over 4.0%. Rikkunshito (TJ-43; Tsumura Co, Tokyo, Japan) was given in three divided doses before meals. We retrospectively investigated its efficacy using pH-multichannel intraluminal impedance before and 7 (6-10) days after starting treatment. Statistical analyses were conducted using Wilcoxon signed-rank test. In the pH analyses alone, the median number of acid reflux episodes >5 min (14 versus 10, p = 0.046) and median acid-clearance time (184 versus 134 s, p = 0.03) decreased significantly, although median decrease in reflux index did not reach significance (16.0 versus 17.9%, p = 0.06). In the combined impedance and pH analyses, the median number (36 versus 36, p = 0.03) and median duration (1.9 versus 1.1%, p = 0.046) of acid reflux decreased significantly; non-acid reflux and bolus clearance time did not change. Rikkunshito effectively reduced acid reflux, but not esophageal clearance, in patients with GERD.

Abstract Objectives: To examine whether maternal–child interaction during feedings was suboptimal in dyads in which the infant had gastroesophageal reflux disease (GERD) and to compare massage therapy to a nonmassage therapy sham treatment in improving the mother–child interaction in these dyads. Design: In this randomized, controlled pilot study, infants received massage therapy (n=18) or a nonmassage touch/holding sham treatment (n=18). Mothers, data collectors, and the investigator who scored the feeding observations were blinded to group assignment. Settings/Location: Dyads were recruited from pediatric care providers in the Denver metropolitan area and online advertisements at the University of Colorado. Treatments were given in the home of the dyad. Participants: Healthy infants, born at 38–42 weeks gestational age, were 5–10 weeks of age at enrollment; had a score of at least 16 on the Infant Gastroesophageal Reflux Questionnaire-Revised; and were diagnosed with GERD by their pediatric provider. Mothers were English speaking and at least 18 years of age. Interventions: Treatments were given for 30 minutes twice weekly for 6 weeks. A certified infant massage therapist administered massage, and a registered nurse or physical therapist experienced with infants administered the control treatment. Outcome Measures: Maternal and infant scores on the Nursing Child Assessment of Feeding Scale (NCAFS). Results: NCAFS scores were significantly lower than national norms. Small to moderately sized effects showing improvement in the massage group relative to the nonmassage group were seen for Sensitivity to Cues, Social-Emotional Growth Fostering, Cognitive Growth Fostering, and Clarity of Cues (Cohen d) and ranged from 0.24 to 0.56. Conclusions: Mothers and infants with GERD experience significantly worse interactions than those without GERD. Massage given twice weekly by a professional trended toward improved interaction during feeding. Daily maternal

Gastroesophageal reflux disease (GERD) has become the most commonly seen gastrointestinal disorder in outpatient clinics. In the United States, around 20% of the general population experience heartburn on a weekly basis. Although clinical complaints can be mild or moderate, patients with GERD may develop further complications, such as peptic strictures, Barrett's esophagus (BE), and even esophageal adenocarcinoma (EAC). Pathologically, GERD is developed as a result of chronic and enhanced exposure of the esophageal epithelium to noxious gastric refluxate. In this review article, we provide an overview of GERD, and then focus on the roles of stromal cells, interleukin 4 (IL-4), and adiponectin in GERD and BE. The importance of inflammation and immunomodulators in GERD pathogenesis is highlighted. Targeting the immunomodulators or inflammation in general may improve the therapeutic outcome of GERD, in particular, in those refractory to proton pump inhibitors. PMID:27441783

Esophageal duplication cysts are rare congenital abnormalities of the foregut and may be associated with other conditions. Association of esophageal duplication with Gastro-Esophageal Reflux Disease (GERD) has not been reported in children. We are reporting a case of a 16 months baby who had antenatal diagnosis of diaphragmatic hernia. Postnatal CTchest, however, suggested a distal esophageal duplication cyst and a contrast esophagogram showed grade-IV GER. A thoracoscopy in another hospital excluded esophageal duplication at that time. Later, he presented with hematemesis in our department and was re-evaluated. Repeat CTconfirmed a persistent 2.5 x 1.3 cm cyst in distal esophagus. Upper GI endoscopy suggested grade-II esophagitis with a wide patent gastro-esophageal junction. The child was treated with left thoracotomy, excision of the duplication cyst and thoracic fundoplication. He had an uneventful post-operative recovery and is doing well at 6 months follow-up.

The Society of Abdominal Radiology established a panel to prepare a consensus statement on the role of barium esophagography in gastroesophageal reflux disease (GERD), as well as recommended techniques for performing the fluoroscopic examination and the gamut of findings associated with this condition. Because it is an inexpensive, noninvasive, and widely available study that requires no sedation, barium esophagography may be performed as the initial test for GERD or in conjunction with other tests such as endoscopy.

To study the specific features of the clinical course of gastroesophageal reflux disease (GERD) associated with duodenogastroesophageal reflux (DGER) in patients with chronic acalculous cholecystitis (CAC) and cholelithiasis (CL), as well as qualitative and quantitative characteristics. The clinical, morphological, motor tonic characteristics of the esophagogastroduodenal area, mucosal microbial biocenosis in the esophagus, stomach, and duodenum were studied in detail in 83 patients with GERD that was associated with DGER and ran concurrently with CAC or CL. Impaired duodenal propulsive activity as a concomitance of the signs of gastrostasis and duodenal dyskinesia with dyscoordination of both anthroduodenal and duodenojejunal propulsion and with the development of duodenogastric reflux and DGER, which in turn determine esophageal and gastric pH values is shown to be of importance in CAC and CL, which match GERD. Abnormal microbiocenosis in the upper digestive tract is characterized by the higher quantitative and qualitative content of the mucous microflora. Opportunistic microorganisms exhibit cytotoxic, hemolytic, lecithinase, caseinolytic, urease, and RNAase activities. The found specific features of the course of GERD associated with DGER in patients with biliary tract abnormalities lead us to search for novel therapeutic approaches based on the correction of digestive motor tonic disorders and abnormal microbiocenoses of the mucous flora in the esophagus, stomach, and duodenum.

Transoral incisionless fundoplication (TIF) was developed in an attempt to create a minimally invasive endoscopic procedure that mimics antireflux surgery. The objective of this trial was to evaluate effectiveness of TIF compared with proton pump inhibition in a population consisting of gastroesophageal reflux disease (GERD) patients controlled with proton pump inhibitors (PPIs) who opted for an endoscopic intervention over lifelong drug dependence. Patients with chronic GERD were randomized (2:1) for TIF or continuation of PPI therapy. American Society of Anesthesiologists >2, body mass index >35 kg/m(2), hiatal hernia >2 cm, and esophageal motility disorders were exclusion criteria. Primary outcome measure was GERD-related quality of life. Secondary outcome measures were esophageal acid exposure, number of reflux episodes, PPI usage, appearance of the gastroesophageal valve, and healing of reflux esophagitis. Crossover for the PPI group was allowed after 6 months. A total of 60 patients (TIF n=40, PPI n=20, mean body mass index 26 kg/m(2), 37 male) were included. At 6 months, GERD symptoms were more improved in the TIF group compared with the PPI group (P<0.001), with a similar improvement of distal esophageal acid exposure (P=0.228) compared with baseline. The pH normalization for TIF group and PPI group was 50% and 63%, respectively. All patients allocated for PPI treatment opted for crossover. At 12 months, quality of life remained improved after TIF compared with baseline (P<0.05), but no improvement in esophageal acid exposure compared with baseline was found (P=0.171) and normalization of pH was accomplished in only 29% in conjunction with deteriorated valve appearances at endoscopy and resumption of PPIs in 61%. Although TIF resulted in an improved GERD-related quality of life and produced a short-term improvement of the antireflux barrier in a selected group of GERD patients, no long-term objective reflux control was achieved.

Spinal kyphotic deformity occasionally results in gastroesophageal reflux disease (GERD). The effects of acid reflux on the esophagus in kyphotic patients are unclear, however, and it is unknown whether acid reflux, endoscopic GERD, and reflux-related symptoms improve following surgical spinal correction in these patients. Herein, we investigated the characteristics of GERD in kyphotic patients and the improvement in GERD following surgical correction. In 48 patients with severe kyphotic deformity scheduled for surgical spinal correction, we conducted esophagogastroduodenoscopy, 24-h pH monitoring and three questionnaire surveys, including the frequency scale for the symptoms of GERD (FSSG). We repeated these measurements after surgical correction and compared pre- and post-surgery values. Of 48 patients, 70.8% [95% CI: 55.9-83.0%, 34/48] had endoscopically evaluated esophageal mucosal injury. Regarding pH before surgery, 64.9% (CI: 47.5-79.8%, 24/37) had abnormal acid reflux (intraesophageal pH < 4 more than 5% of the time). FSSG score was significantly associated with the severity of GERD, and the positive rate was 52.6% (CI: 35.8-69.0%, 20/38). Following surgical correction, esophageal mucosal injury improved endoscopically in 90% of patients, and median total FSSG score significantly decreased from 8 (0-30) to 5 (0-19) (P = 0.005). Regarding pH after surgery, prevalence of abnormal acid reflux decreased from 66.7% (95% CI: 41.0-86.7%) to 33.3% (95% CI: 13.3-59.0%) (P = 0.045). Surgical spinal correction in kyphosis patients improves not only kyphotic deformity-related disorders but also esophageal mucosal injury, abnormal acid reflux, and reflux-related symptoms. © 2015 Japan Gastroenterological Endoscopy Society.

This article reviews the current literature pertaining to the diagnosis and management of gastroesophageal reflux disease (GERD) and hiatal hernia. GERD is one of the most common gastrointestinal disorders in the USA. For effective management, a conclusive diagnosis must be made. Most patients are effectively managed by acid suppression therapy, whereas others require procedural treatment. Endoluminal treatment of GERD is an option, but long-term results of this therapy are unknown. The "gold standard" surgical treatment of GERD is laparoscopic Nissen fundoplication. Large hiatal hernias are difficult to manage with a relatively high rate of recurrent hiatal hernia. Whether or not to use mesh at the hiatus to decrease this occurrence is currently debatable.

To determine the impact of upwards titration of proton pump inhibition (PPI) on acid reflux, symptom scores and histology, compared to clinically successful fundoplication. Two cohorts of long-segment Barrett's esophagus (BE) patients were studied. In group 1 ( n = 24), increasing doses of PPI were administered in 8-wk intervals until acid reflux normalization. At each assessment, ambulatory 24 h pH recording, endoscopy with biopsies and symptom scoring (by a gastroesophageal reflux disease health related quality of life questionnaire, GERD/HRLQ) were performed. Group 2 ( n = 30) consisted of patients with a previous fundoplication. In group 1, acid reflux normalized in 23 of 24 patients, resulting in improved GERD/HRQL scores ( P = 0.001), which were most pronounced after the starting dose of PPI ( P < 0.001). PPI treatment reached the same level of GERD/HRQL scores as after a clinically successful fundoplication ( P = 0.5). Normalization of acid reflux in both groups was associated with reduction in papillary length, basal cell layer thickness, intercellular space dilatation, and acute and chronic inflammation of squamous epithelium. This study shows that acid reflux and symptom scores co-vary throughout PPI increments in long-segment BE patients, especially after the first dose of PPI, reaching the same level as after a successful fundoplication. Minor changes were found among GERD markers at the morphological level.

To assess the performance of self-assessment gastroesophageal reflux disease questionnaire (GerdQ), 24-h impedance monitoring, proton pump inhibitor (PPI) test and intercellular space of esophageal mucosal epithelial cells in the diagnosis of gastroesophageal reflux disease (GERD). Patients with symptoms suspected of GERD were administered the GerdQ and underwent endoscopy (measurement of intercellular space in the biopsy specimen sampling at 2 cm above the Z-line) and 24-h impedance pH monitoring, together with a 2-week experimental treatment with esomeprazole. A total of 636 patients were included for the final analysis, including 352 with GERD. The sensitivity and specificity of GerdQ and 24-h impedance monitoring for diagnosing GERD were 57.7% and 48.9%, and 66.4% and 43.3%, respectively. The sensitivity of 24-h impedance pH monitoring increased to 93.7%. The sensitivity and specificity of dilated intercellular spaces (DIS) (≥0.9 μm) for diagnosing GERD were 61.2% and 56.1%, respectively, whereas those for PPI test were 70.5% and 44.4%. GerdQ score or PPI test alone cannot accurately diagnose GERD in a Chinese population suspected of GERD. A definitive diagnosis of GERD still depends on endoscopy or 24-h pH monitoring. 24-h impedance pH monitoring may increase the sensitivity for diagnosing GERD by 20%; however, when used alone, it results in poor specificity in patients without acid suppressive therapy. © 2014 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

To evaluate the manometric changes, function, and impact of magnetic sphincter augmentation (MSA) on the lower esophageal sphincter (LES). Implantation of a MSA around the gastroesophageal junction has been shown to be a safe and effective therapy for gastroesophageal reflux disease, but its effect on the LES has not been elucidated. Retrospective case control study (n = 121) evaluating manometric changes after MSA. Inclusion criteria consisted of a confirmed diagnosis of gastroesophageal reflux disease by an abnormal esophageal pH study (body mass index <35 kg/m, hiatal hernia <3 cm, and absence of endoscopic Barrett disease). Manometric changes, pH testing, and proton pump inhibitor use were assessed preoperatively and 6 and 12 months after MSA. MSA was associated with an overall increase in the median LES resting pressure (18 pre-MSA vs 23 mm Hg post-MSA; P = 0.0003), residual pressure (4 vs 9 mm Hg; P < 0.0001), and distal esophageal contraction amplitude (80 vs 90 mm Hg; P = 0.02). The percent peristalsis remained unaltered (94% vs 87%; P = 0.71).Overall, patients with a manometrically defective LES were restored 67% of the time to a normal sphincter with MSA. Those with a structurally defective or severely defective LES improved to a normal LES in 77% and 56% of patients, respectively. Only 18% of patients with a normal preoperative manometric LES deteriorated to a lower category. MSA results in significant manometric improvement of the LES without apparent deleterious effects on the esophageal body. A manometrically defective LES can be restored to normal sphincter, whereas a normal LES remains stable.

AIM To elucidate the factors associated with residual gastroesophageal reflux disease (GERD) symptoms in patients receiving proton pump inhibitor (PPI) maintenance therapy in clinical practice. METHODS The study included 39 GERD patients receiving maintenance PPI therapy. Residual symptoms were assessed using the Frequency Scale for Symptoms of GERD (FSSG) questionnaire and the Gastrointestinal Symptom Rating Scale (GSRS). The relationships between the FSSG score and patient background factors, including the CYP2C19 genotype, were analyzed. RESULTS The FSSG scores ranged from 1 to 28 points (median score: 7.5 points), and 19 patients (48.7%) had a score of 8 points or more. The patients’ GSRS scores were significantly correlated with their FSSG scores (correlation coefficient = 0.47, P < 0.005). In erosive esophagitis patients, the FSSG scores of the CYP2C19 rapid metabolizers (RMs) were significantly higher than the scores of the poor metabolizers and intermediate metabolizers (total scores: 16.7 ± 8.6 vs 7.8 ± 5.4, P < 0.05; acid reflux-related symptom scores: 12 ± 1.9 vs 2.5 ± 0.8, P < 0.005). In contrast, the FSSG scores of the CYP2C19 RMs in the non-erosive reflux disease patients were significantly lower than those of the other patients (total scores: 5.5 ± 1.0 vs 11.8 ± 6.3, P < 0.05; dysmotility symptom-related scores: 1.0 ± 0.4 vs 6.0 ± 0.8, P < 0.01). CONCLUSION Approximately half of the GERD patients receiving maintenance PPI therapy had residual symptoms associated with a lower quality of life, and the CYP2C19 genotype appeared to be associated with these residual symptoms.

Numerous questionnaires with a wide variety of characteristics have been developed for the assessment of gastroesophageal reflux disease (GERD). Four well-defined dimensions are noticeable in these GERD questionnaires, which are symptoms, response to treatment, diagnosis, and burden on the quality of life of GERD patients. The aim of this review is to develop a complete overview of all available questionnaires, categorized per dimension of the assessment of GERD. A systematic search of the literature up to January 2013 using the Pubmed database and the Embase database, and search of references and conference abstract books were conducted. A total number of 65 questionnaires were extracted and evaluated. Thirty-nine questionnaires were found applicable for the assessment of GERD symptoms, three of which are generic gastrointestinal questionnaires. For the assessment of response to treatment, 14 questionnaires were considered applicable. Seven questionnaires with diagnostic purposes were found. In the assessment of quality of life in GERD patients, 18 questionnaires were found and evaluated. Twenty questionnaires were found to be used for more than one assessment dimension, and eight questionnaires were found for GERD assessment in infants and/or children. A wide variety of GERD questionnaires is available, of which the majority is used for assessment of GERD symptoms. Questionnaires differ in aspects such as design, validation and translations. Also, numerous multidimensional questionnaires are available, of which the Reflux Disease Questionnaire is widely applicable. We provided an overview of GERD questionnaires to aid investigators and clinicians in their search for the most appropriate questionnaire for their specific purposes. © 2013 International Society for Diseases of the Esophagus.

Fats cause reflux symptoms in many patients and cholecystokinin (CCK) may play a role. This study was designed to evaluate the effects of intraduodenal nutrient infusion on serum CCK levels, lower esophageal sphincter (LES) pressure, and gastroesophageal reflux (GER). Twenty-four asymptomatic volunteers were studied. A Dent sleeve catheter assessed LES function while an impedance-pH catheter measured reflux events. Participants were randomized to fat (F), carbohydrate (C) or protein (P) infusion. Serum CCK and LES pressures were measured at baseline and after nutrient infusion. Baseline LES pressures and CCK levels were similar in all three groups. A significant linear decrease was found in LES pressure during F, but not C or P, infusion (P=0.004). A significant interaction effect was noted between the infusion groups and CCK levels (P=0.002). A significant linear increase was noted in CCK levels during F but not during C or P infusion (P=0.02). A significant inverse correlation was found between CCK levels and LES pressure (ρ=-0.43; P=0.04). Esophageal acid exposure was significantly increased in the F infusion group (median; interquartile range: 1.10%; 0.25-4.7%) compared to both the C (0.03%; 0.00-0.39%) and P infusion (0.03%; 0.00-0.39%) groups (P=0.04). Intraduodenal F infusion was associated with an increase in CCK levels, while P and C were not. LES pressure decreased significantly after fat infusion and reflux events were more frequent. Fat-induced CCK release is another mechanism that contributes to GER. © 2011 Blackwell Publishing Ltd.

Esomeprazole is commonly administered with food; however, clinical data to support this practice are lacking. We aimed to determine the effect of postprandial ingestion of esomeprazole on reflux symptoms among patients with gastroesophageal reflux disease (GERD). Consecutive patients with GERD adequately controlled with esomeprazole 40 mg daily, entered a 2-week lead-in period during which esomeprazole was administered 30 min before breakfast. Patients were then randomized to continue preprandial ingestion or to ingest esomeprazole following a standardized meal. Outcomes included GERD frequency and severity indices, GERD-health-related quality of life (GERD-HRQL) questionnaire and Short Form 36 (SF-36). Thirty-two patients (17 [53.1%] men, aged 53.5 ± 17.2 years) were included, and 16 (50%) switched to postprandial ingestion of esomeprazole. GERD frequency and severity decreased in both groups (Δ9.0 ± 7.2 vs. Δ10.0 ± 8.1, p = 0.29; Δ6.6 ± 6.8 vs. Δ10.2 ± 7.4, p = 0.57 in postprandial group vs. controls, for frequency and severity, respectively). GERD-HRQL improved in both study groups to a similar degree (Δ10.7 ± 10.5 vs. Δ10.0 ± 13.8, p = 0.97). All SF-36 subscores increased in both groups to a similar degree. In a mixed linear model, there were no differences between the study groups in the changes observed in GERD frequency (p = 0.49), severity (p = 0.32), and GERD-HRQL (p = 0.98) during the study period. Switching to postprandial administration of esomeprazole is not associated with deterioration in reflux symptoms among patients with GERD. Esomeprazole seems to remain efficacious when administered after meals. © 2018 S. Karger AG, Basel.

We present our observational study on 40 patients treated with the medical device containing sodium hyaluronic acid and magnesium alginate, performing a lubricating and hydrating action. This device is in the form of a gel, with topical action to contrast gastroesophageal reflux and to exert a mechanical role of protection of the mucosal tissues (mouth-pharyngo-esophageal mucosa and gastric mucose.). Forty patients were recruited aged between 22- and 72-years-old with painful dyspeptic Gastro Esophageal Reflux Disease (GERD) symptomatology in acute or in clinical phase (25 patients) and with pharyngolaryngo- tracheal symptomatology (15 patients). Patients were divided into two clinical groups: Group A was treated with the medical device, while Group B with conventional treatments without the medical device. Subjects of both groups were also treated with proton pump inhibitors (PPIs). Follow-up was at 10, 20 and 30 days and patients were evaluated for reduction of their subjective symptoms, reduction of symptomatic and occasional therapies, reduction of inflammatory process or disappearance of epithelial lesions of the examined mucosa, healing process. The reduction of subjective symptoms was observed at 10 days in the patient with food bolus (disappearance after 5 days) and in patients with a reduction of 70%. A relevant reduction in the use of symptomatic drugs was noted. Our data are relevant considering symptom relief (heartburn, reflux and dyspepsia). New scenarios for the treatment of inflammatory diseases of the digestive and respiratory tract mucosa are at the horizon. Interdisciplinary translational research brings to the development of novel medical devices (as the one described in this study) with a high safety profile, and extremely active on the inflammation-repair-regeneration complex of different tissues and organs.

Background & Aims Dental erosion is a complication of gastroesophageal reflux (GER) in adults; in children, it is not clear if GER has a role in dental pathologic conditions. Dietary intake, oral hygiene, high bacterial load, and decreased salivary flow might contribute independently to GER development or dental erosion, but their potential involvement in dental erosion from GER is not understood. We investigated the prevalence of dental erosion among children with and without GER symptoms, and whether salivary flow rate or bacterial load contribute to location-specific dental erosion. Methods We performed a cross-sectional study of 59 children (ages 9–17 y) with symptoms of GER and 20 asymptomatic children (controls); all completed a questionnaire on dietary exposure. Permanent teeth were examined for erosion into dentin, erosion locations, and affected surfaces. The dentist was not aware of GER status, nor was the gastroenterologist aware of dental status. Stimulated salivary flow was measured and salivary bacterial load was calculated for total bacteria, Streptococcus mutans and Lactobacilli. Results Controlling for age, dietary intake, and oral hygiene, there was no association between GER symptoms and dental erosion, by tooth location or affected surface. Salivary flow did not correlate with GER symptoms or erosion. Erosion location and surface were independent of total bacteria and levels of Streptococcus mutans and Lactobacilli. Conclusions Location-specific dental erosion is not associated with GER, salivary flow, or bacterial load. Prospective studies are required to determine the pathogenesis of GER-associated dental erosion and the relationship between dental caries to GER and dental erosion. PMID:21820389

The association of esophageal motility and gastroesophageal reflux symptoms with respiratory symptoms is not well established in patients with chronic obstructive pulmonary disease (COPD). The aim of this work is to study the abnormalities of esophageal function in COPD patients and study its relation to smoking index, body mass index and indices of hyperinflation. This study included 40 male COPD patients and 10 healthy controls. The patients and controls were subjected to spirometry, body plethysmography, esophageal manometry and 24hr pH-metry. Upper gastrointestinal symptoms were found in 55% of patients, hypotensive upper esophageal sphincter pressure in 65% of patients and hypotensive lower esophageal sphincter pressure in 52.5% of patients. Pathological acid reflux was found in 35% of patients. The severity of GERD increased with increased age, smoking index and body mass index, p<0.005. There was negative correlation between LESP and UESP compared with indices of hyperinflation, p<0.001. There was high prevalence of esophageal motility disorders in COPD patients, LESP and UESP were significantly negatively correlated to indices of hyperinflation. There was a high prevalence of GERD in COPD patents especially elderly, severe stage of COPD, high smoking index and high body mass index (BMI).

Gastroesophageal reflux in neonates is frequently reported by parents, potentially motivating changes in infant feeding mode and/or addition of solid food. The authors prospectively analyzed associations between repeated measurement of feeding modes and reflux in infancy. The Infant Feeding Practices Study II, conducted between 2005 and 2007 (2,841 infants), provides data on reflux and feeding modes at nine time points from months 1 to 12. Feeding modes were defined based on direct breastfeeding, feeding of bottled human milk, formula feeding, their combinations, and use of solid food. Repeated measurements were investigated using 1-month delayed models to estimate risk ratios (RRs) and their 95% confidence intervals (CIs). Risk ratios of different feeding modes were estimated for reflux; addressing a reverse association, RRs for feeding mode were estimated as responses to prior reflux. Compared to direct breastfeeding, combinations with formula feeding showed a statistically significant risk for reflux (bottled human milk plus formula feeding: RR = 2.19, 95% CI [1.11, 4.33]; formula feeding: RR = 1.95, 95% CI [1.39, 2.74]; and mixed breastfeeding plus formula feeding: RR = 1.59, 95% CI [1.40, 2.42]). Addition of solid food was not protective (RR = 1.21, 95% CI [0.86, 1.70]). Analyses of reverse association (reflux → feeding) showed fewer breastfed infants among those with reflux in the prior month. Any combination of infant feeding with formula seems to be a risk for reflux. Although breastfeeding was protective, mothers with a child with reflux were more likely to wean their child.

Gastroesophageal reflux disease (GERD) has become the most commonly seen gastrointestinal disorder in outpatient clinics. In the United States, around 20% of the general population experience heartburn on a weekly basis. Although clinical complaints can be mild or moderate, patients with GERD may develop further complications, such as peptic strictures, Barrett's esophagus (BE), and even esophageal adenocarcinoma. Pathologically, GERD is developed as a result of chronic and enhanced exposure of the esophageal epithelium to noxious gastric refluxate. In this review article, we provide an overview of GERD and then focus on the roles of stromal cells, interleukin 4, and adiponectin in GERD and BE. The importance of inflammation and immunomodulators in GERD pathogenesis is highlighted. Targeting the immunomodulators or inflammation in general may improve the therapeutic outcome of GERD, in particular, in those refractory to proton pump inhibitors. © 2016 New York Academy of Sciences.
