About one-third of patients with suspected gastro-oesophageal reflux disease (GERD) do not respond symptomatically to proton pump inhibitors (PPIs). Many of these patients do not suffer from GERD, but may have underlying functional heartburn or atypical chest pain. Other causes of failure to respond to PPIs include inadequate acid suppression, non-acid reflux, oesophageal hypersensitivity, oesophageal dysmotility and psychological comorbidities. Functional oesophageal tests can exclude cardiac and structural causes, as well as help to confi rm or exclude GERD. The use of PPIs should only be continued in the presence of acid reflux or oesophageal hypersensitivity for acid reflux-related events that is proven on functional oesophageal tests.

Gastro-Oesophageal Reflux in Noncystic Fibrosis Bronchiectasis

Directory of Open Access Journals (Sweden)

Annemarie L. Lee

2011-01-01

Full Text Available The clinical presentation of noncystic fibrosis bronchiectasis may be complicated by concomitant conditions, including gastro-oesophageal reflux (GOR. Increased acidic GOR is principally caused by gastro-oesophageal junction incompetence and may arise from lower oesophageal sphincter hypotension, including transient relaxations, hiatus hernia, and oesophageal dysmotility. Specific pathophysiological features which are characteristic of respiratory diseases including coughing may further increase the risk of GOR in bronchiectasis. Reflux may impact on lung disease severity by two mechanisms, reflex bronchoconstriction and pulmonary microaspiration. Symptomatic and clinically silent reflux has been detected in bronchiectasis, with the prevalence of 26 to 75%. The cause and effect relationship has not been established, but preliminary reports suggest that GOR may influence the severity of bronchiectasis. Further studies examining the implications of GOR in this condition, including its effect across the disease spectrum using a combination of diagnostic tools, will clarify the clinical significance of this comorbidity.

The management of gastro-oesophageal reflux disease.

If there are no features of serious disease, suspected gastro-oesophageal reflux disease can be initially managed with a trial of a proton pump inhibitor for 4-8 weeks. This should be taken 30-60 minutes before food for optimal effect. Once symptoms are controlled, attempt to withdraw acid suppression therapy. If symptoms recur, use the minimum dose that controls symptoms. Patients who have severe erosive oesophagitis, scleroderma oesophagus or Barrett's oesophagus require long-term treatment with a proton pump inhibitor. Lifestyle modification strategies can help gastro-oesophageal reflux disease. Weight loss has the strongest evidence for efficacy. Further investigation and a specialist referral are required if there is no response to proton pump inhibitor therapy. Atypical symptoms or signs of serious disease also need investigation.

Food-stimulated gastro-oesophageal reflux demonstrated by barium examination

Energy Technology Data Exchange (ETDEWEB)

Christiansen, T.; Thommesen, P.

A prospective investigation on gastro-oesophageal reflux in 97 consecutive patients has been carried out by means of a barium examination employing the conventional method and after food stimulation. Gastro-oesophageal reflux was observed in 38 patients with and 15 patients without oesophageal symptoms. Gastro-oesophageal reflux was induced by two mechanisms, an active component after food stimulation and a passive component after the conventional method including respiratory manoeuvres and leg raising. In 32 patients, only the active component could be demonstrated and in 6 patients only the passive component. In the remaining 15 patients both active and passive components occurred. The clinical significance of the active and passive components in gastro-oesophageal reflux needs further investigation.

Gastro-oesophageal reflux disease (GERD) adversely impacts on sleep, but the mechanism remains unclear. To review the literature concerning gastro-oesophageal reflux during the sleep period, with particular reference to the sleep/awake state at reflux onset. Studies identified by systematic literature searches were assessed. Overall patterns of reflux during the sleep period show consistently that oesophageal acid clearance is slower, and reflux frequency and oesophageal acid exposure are higher in patients with GERD than in healthy individuals. Of the 17 mechanistic studies identified by the searches, 15 reported that a minority of reflux episodes occurred during stable sleep, but the prevailing sleep state at the onset of reflux in these studies remains unclear owing to insufficient temporal resolution of recording or analysis methods. Two studies, in healthy individuals and patients with GERD, analysed sleep and pH with adequate resolution for temporal alignment of sleep state and the onset of reflux: all 232 sleep period reflux episodes evaluated occurred during arousals from sleep lasting less than 15 s or during longer duration awakenings. Six mechanistic studies found that transient lower oesophageal sphincter relaxations were the most common mechanism of sleep period reflux. Contrary to the prevailing view, subjective impairment of sleep in GERD is unlikely to be due to the occurrence of reflux during stable sleep, but could result from slow clearance of acid reflux that occurs during arousals or awakenings from sleep. Definitive studies are needed on the sleep/awake state at reflux onset across the full GERD spectrum. © 2013 John Wiley & Sons Ltd.

Full Text Available Background: Gastro-oesophageal reflux may accompany the corrosive oesophageal damage caused by the ingestion of corrosive substances and affect its treatment. The factors that affect the development of reflux in these cases and their effects on treatment still remain unclear. Aims: Our aim is to investigate the prevalence of gastro-oesophageal reflux in children with corrosive oesophageal strictures, the risk factors affecting this prevalence and the effects of gastro-oesophageal reflux on treatment. Study Design: Case-control study. Methods: We enrolled 52 patients with oesophageal stricture due to corrosive substance ingestion who were referred to our clinic between 2003 and 2010. Groups, which were determined according to the presence of gastro-oesophageal reflux (GER, were compared with each other in terms of clinical findings, results of examination methods, characteristics of the stricture and success of the treatment. Results: The total number of patients in our study was 52; 30 of them were male and 22 of them were female. The mean age of our study population was 4.2±2.88 years. Thirty-three patients had gastro-oesophageal reflux (63.5%. Patients who had strictures caused by the ingestion of alkali substances were 1.6-times more likely to have reflux. There were no differences between patients with or without reflux in terms of number and localisation of strictures. Mean distance of stricture was longer in patients with reflux (3.7±1.8 cm than in patients without (2.2±1.0 cm (p0.05. Conclusion: Corrosive oesophageal stricture was usually accompanied by gastro-oesophageal reflux and the length of stricture is an important risk factor. Negative effects of reflux over dilatation treatment have not yet been demonstrated in the short-term. Nevertheless, this frequent rate of reflux may eventually increase the risk of oesophagitis and Barrett’s oesophagus; therefore, we suggest that these effects should be prospectively evaluated in a

The influence of Cisapride on food-stimulated gastro-oesophageal reflux meachanisms was studied in a double-blind cross-over investigation in 24 consecutive patients selected by endoscopy, 12 with microscopical evidence of gastro-oesophageal reflux and 12 with additional macroscopic oesoghagitis. 63% had food-stimulated gastro-oesophageal reflux, and Cisapride significantly reduced the tendency to gastro-oesophageal reflux and mucosal contact time between gastric content and the oesophageal mucosa in 73% of these patients. It is concluded that Cisapride could be valuable in the treatment of gastro-oesophageal reflux. (orig.) [de

Detection of gastro-oesophageal reflux disease. The clinical value of a barium examination after food stimulation

Energy Technology Data Exchange (ETDEWEB)

Christiansen, T.; Ravnsbaek, J.; Toettrup, A.; Funch-Jensen, P.; Thommesen, P.

In a prospective study a barium examination combined with food stimulation was compared with the acid reflux test in 30 consecutive patients with symptoms of gastro-oesophageal reflux. Both methods were further compared with endoscopy and histology. Gastro-oesophageal reflux could be demonstrated by the radiologic examination in 22 patients and by the acid reflux test in 23 patients. By combining the two methods gastro-oesophageal reflux could be demonstrated in 27 patients. Comparing the two methods with symptoms, endoscopy, and histology they seemed to be of equal value. Accordingly, a food-stimulated barium examination is recommended as the first method for demonstrating gastro-oesophageal reflux because it is simple and well-tolerated by the patient.

Tobacco smoking, alcohol consumption and gastro-oesophageal reflux disease.

2017-10-01

Gastro-oesophageal reflux disease (GORD) develops when reflux of gastric content causes troublesome symptoms or complications. The main symptoms are heartburn and acid regurgitation and complications include oesophagitis, strictures, Barrett's oesophagus and oesophageal adenocarcinoma. In addition to hereditary influence, GORD is associated with lifestyle factors, mainly obesity. Tobacco smoking is regarded as an aetiological factor of GORD, while alcohol consumption is considered a triggering factor of reflux episodes and not a causal factor. Yet, both tobacco smoking and alcohol consumption can reduce the lower oesophageal sphincter pressure, facilitating reflux. In addition, tobacco smoking reduces the production of saliva rich in bicarbonate, which is important for buffering and clearance of acid in the oesophagus. Alcohol also has a direct noxious effect on the oesophageal mucosa, which predisposes to acidic injury. Tobacco smoking cessation reduces the risk of GORD symptoms and avoidance of alcohol is encouraged in individuals where alcohol consumption triggers reflux. Copyright © 2017 Elsevier Ltd.

Gastro-oesophageal Reflux Disease: An Update

Full Text Available Gastro-oesophageal reflux disease (GERD is a disorder in which reflux of stomach contents causes troublesome symptoms and/or complications and which affects health-related quality of life. It is one of the commonest disorders and appears to be increasing in incidence. The mechanisms leading to reflux are complex and multifactorial. The lower oesophageal sphincter (LES is an important part of the gastro-oesophageal barrier. Transient LES relaxations (TLESRs lead to reflux as these vagally mediated motor patterns cause relaxation of the LES and also result in oesophageal shortening and inhibition of the crural diaphragm. Heartburn and regurgitation are the characteristic symptoms of GERD. A clinical diagnosis of GERD can be made with typical symptoms. Oesophagitis is seen in a minority of patients with GERD. Lifestyle modification is widely advocated for patients with GERD. For short-term relief of symptoms of mild GERD, antacids/alginates are frequently used but they do not heal oesophagitis. Both histamine 2 receptor antagonists (H2RA and proton pump inhibitors (PPI have been shown to heal and prevent relapse of oesophagitis, although PPIs have been shown to be superior. The PPIs are the recommended first-line therapy for erosive oesophagitis and initial management of non-erosive reflux disease. Maintenance PPI therapy should be given to patients with oesophagitis, those who have recurrence of symptoms after discontinuation of medication and for those with complications of GERD.

Respiratory and laryngeal symptoms secondary to gastro-oesophageal reflux

Science.gov (United States)

Rafferty, G; Mainie, I; McGarvey, L P A

2011-01-01

Gastro-oesophageal reflux may cause a range of laryngeal and respiratory symptoms. Mechanisms responsible include the proximal migration of gastric refluxate beyond the upper oesophageal sphincter causing direct irritation of the larynx and lower airway. Alternatively, refluxate entering the distal oesophagus alone may stimulate oesophageal sensory nerves and indirectly activate airway reflexes such as cough and bronchospasm. Recognising reflux as a cause for these extraoesophageal symptoms can be difficult as many patients do not have typical oesophageal symptoms (eg, heartburn) and clinical findings on laryngoscopy are not very specific. Acid suppression remains an effective treatment in the majority of patients but there is growing appreciation of the need to consider and treat non-acid and volume reflux. New opinions about the role of existing medical and surgical (laparoscopic techniques) treatment are emerging and a number of novel anti-reflux treatments are under development. PMID:28839612

To evaluate the diagnosis and management of reflux and gastro-oesophageal reflux disease (GORD) in infants aged reflux and GORD and their management including prescribing of acid-suppressant medicines (proton pump inhibitors (PPIs) and histamine receptor antagonists (H2RAs)) and counselling, advice or education. Of all infants' visits, 512 (2.7%) included a diagnosis of reflux (n=413, 2.2%) or GORD (n=99, 0.5%). From 2006 to 2016, diagnostic rates decreased for reflux and increased for GORD. Prescribing of acid suppressants occurred in 43.6% visits for reflux and 48.5% visits for GORD, similar to rates of counselling, advice or education (reflux: 38.5%, GORD: 43.4% of visits). Prescribing of PPIs increased (statistically significant only for visits for reflux), while prescribing of H2RAs decreased. Overprescribing of acid suppressants to infants may be occurring. In infants, acid-suppressant medicines are no better than placebo and may have significant negative side effects; however, guidelines are inconsistent. Clear, concise and consistent guidance is needed. GPs and parents need to understand what is normal and limitations of medical therapy. We need a greater understanding of the influences on GP prescribing practices, of parents' knowledge and attitudes and of the pressures on parents of infants with these conditions. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Gastro-oesophageal reflux may accompany the corrosive oesophageal damage caused by the ingestion of corrosive substances and affect its treatment. The factors that affect the development of reflux in these cases and their effects on treatment still remain unclear. Our aim is to investigate the prevalence of gastro-oesophageal reflux in children with corrosive oesophageal strictures, the risk factors affecting this prevalence and the effects of gastro-oesophageal reflux on treatment. Case-control study. We enrolled 52 patients with oesophageal stricture due to corrosive substance ingestion who were referred to our clinic between 2003 and 2010. Groups, which were determined according to the presence of gastro-oesophageal reflux (GER), were compared with each other in terms of clinical findings, results of examination methods, characteristics of the stricture and success of the treatment. The total number of patients in our study was 52; 30 of them were male and 22 of them were female. The mean age of our study population was 4.2±2.88 years. Thirty-three patients had gastrooesophageal reflux (63.5%). Patients who had strictures caused by the ingestion of alkali substances were 1.6-times more likely to have reflux. There were no differences between patients with or without reflux in terms of number and localisation of strictures. Mean distance of stricture was longer in patients with reflux (3.7±1.8 cm) than in patients without (2.2±1.0 cm) (preflux. Patients with long stricture were 1.9-times more likely to have reflux. Dilatation treatment was successful in 69.6% of patients with reflux and in 78.9% of patients without. The mean treatment period was 8.41±6.1 months in patients with reflux and 8.21±8.4 months in the other group. There was no significant difference between groups in terms of frequency of dilatation and dilator diameters (p>0.05).

A more prominent role for the youth healthcare physician: Youth Healthcare physicians reflect on the Dutch Paediatric Association (NVK) guideline entitled 'Gastro-oesophageal reflux (disease) in children aged 0-18 years'. This guideline states that medicinal treatment is given to these children too often. Dutch Youth Healthcare physicians see a large number of children with gastro-oesophageal reflux, with or without additional symptoms. The most common symptoms (crying and diminished weight gain) might be present even in the absence of reflux. Parents should be given advice and support when they are worried about reflux, crying or low weight gain. A lower weight gain curve on the growth chart is normal in breastfed children, and crying might be due to factors such as lack of routine or stimulus reduction. Overfeeding might also be the cause. Parents should be supported and followed up, with or without treatment, as necessary. Youth Healthcare professionals could perform this task.

Control of transient lower oesophageal sphincter relaxations and reflux by the GABAB agonist baclofen in patients with gastro-oesophageal reflux disease

Zhang, Q; Lehmann, A; Rigda, R; Dent, J; Holloway, R H

2002-01-01

Background and aims: Transient lower oesophageal sphincter relaxations (TLOSRs) are the major cause of gastro-oesophageal reflux in normal subjects and in most patients with reflux disease. The gamma aminobutyric acid (GABA) receptor type B agonist, baclofen, is a potent inhibitor of TLOSRs in normal subjects. The aim of this study was to investigate the effect of baclofen on TLOSRs and postprandial gastro-oesophageal reflux in patients with reflux disease. Methods: In 20 patients with reflux disease, oesophageal motility and pH were measured, with patients in the sitting position, for three hours after a 3000 kJ mixed nutrient meal. On separate days at least one week apart, 40 mg oral baclofen or placebo was given 90 minutes before the meal. Results: Baclofen reduced the rate of TLOSRs by 40% from 15 (13.8–18.3) to 9 (5.8–13.3) per three hours (preflux episodes by 43% from 7.0 (4.0–12.0) to 4.0 (1.5–9) per three hours (median (interquartile range); preflux disease, the GABAB agonist baclofen significantly inhibits gastro-oesophageal reflux episodes by inhibition of TLOSRs. These findings suggest that GABAB agonists may be useful as therapeutic agents for the management of reflux disease. PMID:11772961

Squamous cell carcinoma of the oesophagus is a common cancer among South Africans. Due to the absence of effective screening and surveillance programme for early detection and late presentation, squamous cell carcinoma of the oesophagus is usually diagnosed at an advanced stage or when metastasis has already occurred. The 5-year survival is often quoted at 5%-10%, which is poor. To determine the association between oesophageal squamous cell carcinoma (OSCC) and non-acid gastro-oesophageal reflux disease. Study design: A cross-sectional case-control analytical study of patients referred to the Gastroenterology Division of Steve Biko Academic Hospital in Pretoria, South Africa. All patients had combined multichannel impedance and pH studies done and interpreted after upper gastroscopy using the American College of Gastroenterology guidelines by two clinicians. Thirty-two patients with OSCC were recruited: non-acid reflux was found in 23 patients (73%), acid reflux in 2 patients (6%) and 7 patients (22%) had normal multichannel impedance and pH studies.Forty-nine patients matched by age, gender and race were recruited as a control group. Non-acid reflux was found in 11 patients (22%), acid reflux in 31 patients (63%) and 7 patients (14%) had normal multichannel impedance and pH monitoring study. The significance of the association between non-acid reflux and OSCC was tested using χ 2 , and simple logistic regression was used to adjust for the effects of potential confounders.The OR of developing OSCC in patients with non-acid gastro-oesophageal reflux was 8.8 (95% CI 3.2 to 24.5, P<0.0001) in this South African group.Alcohol and smoking had no effect on these results.

Gastro-oesophageal reflux is obviously caused by an insufficiency of the dilatable lower end of the oesophagus. The physiological pressure acting on it corresponds to 15-30 mm Hg so that the gastric juice is prevented from entering the oesophagus. Reflux is associated with a reduction of that pressure. Many causes may be responsible, although hiatal hernia, where confirmed, will only play a secondary part. In half of the 74 examined elderly patients, gastro-oesophageal reflux was confirmed by radiology. About half of these suffered also from hiatal hernia which was a sliding hernia in 75 per cent of the cases. In about 25 per cent of the patients suffering from gastro-oesophageal reflux, signs of oesophagitis were discovered by radiology. There was no correlation between overweight and the incidence of reflux, but hiatus hernia and a positive Broca test were distinctly related to one another. In patients with gastro-oesophageal reflux, vomiting as a key symptom was more frequently confirmed than in patients without reflux.

Objectives To ascertain the prevalence of Helicobacter pylori in patients with gastro-oesophageal reflux disease and its association with the disease. Design Systematic review of studies reporting the prevalence of H pylori in patients with and without gastro-oesophageal reflux disease. Data sources Four electronic databases, searched to November 2001, experts, pharmaceutical companies, and journals. Main outcome measure Odds ratio for prevalence of H pylori in patients with gastro-oesophageal reflux disease. Results 20 studies were included. The pooled estimate of the odds ratio for prevalence of H pylori was 0.60 (95% confidence interval 0.47 to 0.78), indicating a lower prevalence in patients with gastro-oesophageal reflux disease. Substantial heterogeneity was observed between studies. Location seemed to be an important factor, with a much lower prevalence of H pylori in patients with gastro-oesophageal reflux disease in studies from the Far East, despite a higher overall prevalence of infection than western Europe and North America. Year of study was not a source of heterogeneity. Conclusion The prevalence of H pylori infection was significantly lower in patients with than without gastro-oesophageal reflux, with geographical location being a strong contributor to the heterogeneity between studies. Patients from the Far East with reflux disease had a lower prevalence of H pylori infection than patients from western Europe and North America, despite a higher prevalence in the general population. What is already known on this topicThe relation between H pylori infection and gastro-oesophageal reflux disease is controversialStudies on the prevalence of H pylori in patients with gastro-oesophageal reflux disease have given conflicting resultsRecent guidelines recommend eradication of H pylori in patients requiring long term proton pump inhibitors, essentially for reflux diseaseWhat this study addsDespite heterogeneity between studies, the prevalence of H pylori was

AIMS: The primary aim was to assess whether there were differences in symptoms, laboratory data, and oesophageal pH-metry between infants with primary gastro-oesophageal reflux and those with reflux secondary to cows' milk protein allergy (CMPA). PATIENTS AND METHODS: 96 infants (mean(SD) age 7.8(2.0) months) with either primary gastro-oesophageal reflux, reflux with CMPA, CMPA only, or none of these (controls) were studied. Symptoms, immunochemical data, and oesophageal pH were compared between the four groups and the effect of a cows' milk protein-free diet on the severity of symptoms was also assessed. RESULTS: 14 out of 47(30%) infants with gastro-oesophageal reflux had CMPA. These infants had similar symptoms to those with primary gastro-oesophageal reflux but higher concentrations of total IgE and circulating eosinophils (p gastro-oesophageal reflux secondary to CMPA and in 24 of 25 infants with CMPA only. No infants with primary gastro-oesophageal reflux and none of the controls had this pattern. A cows' milk protein-free diet was associated with a significant improvement in symptoms only in infants with gastro-oesophageal reflux with CMPA. CONCLUSION: A characteristic oesophageal pH pattern is useful in distinguishing infants with gastro-oesophageal reflux associated with CMPA. PMID:8813871

Atrial fibrillation and gastro-oesophageal reflux are common manifestations in daily practice. The atria and the oesophagus are closely located and have similar nerve innervations. Over the last years, it has been observed that atrial fibrillation development and reflux disease could be related. Atrial fibrillation occurrence could be due to vagal nerve overstimulation. This, in association with vagal nerve-mediated parasympathetic stimulation, has also been observed in patients with gastro-oesophageal reflux. These mechanisms, in addition to inflammation, seem to be implicated in the pathophysiology of both diseases. Despite these associations supported by clinical and experimental studies, this relationship is still considered controversial. This review summarizes critical data regarding the association of gastro-oesophageal reflux and atrial fibrillation as well as their clinical implications.

About half of these suffered also from hiatal hernia which was a sliding hernia in 75 per cent of the cases. In about 25 per cent of the patients suffering from gastro-oesophageal reflux, signs of oesophagitis were discovered by radiology. There was no correlation between overweight and the incidence of reflux, but hiatus hernia and a positive Broca test were distinctly related to one another. In patients with gastro-oesophageal reflux, vomiting as a key symptom was more frequently confirmed than in patients without reflux. (orig./WU) [de

Sleeve gastrectomy is rapidly becoming popular as a standalone bariatric operation. At the same time, there are valid concerns regarding its long-term durability and postoperative gastro-oesophageal reflux disease. Though gastric bypass remains the gold standard bariatric operation, it is not suitable for all patients. Sleeve gastrectomy is sometimes the only viable option. Patients with inflammatory bowel disease, liver cirrhosis, significant intra-abdominal adhesions involving small bowel and those reluctant to undergo gastric bypass could fall in this category. It is widely recognised that some patients report worsening of their gastro-oesophageal reflux disease after sleeve gastrectomy. Still, others develop de novo reflux. This review examines if it is possible to identify these patients prior to surgery and thus prevent postoperative gastro-oesophageal reflux disease after sleeve gastrectomy.

The aim of this study was to explore the pathogenesis of chronic cough caused by non-acid reflux. Seven patients with chronic cough due to non-acid reflux, 12 patients with chronic cough due to acid reflux, 10 patients with gastro-oesophageal reflux disease without cough and 12 healthy volunteers were recruited for the study. All subjects underwent oesophageal multi-channel intraluminal impedance measurements combined with pH monitoring, and assessment of cough reflex sensitivity to capsaicin and induced sputum cytology. The concentrations of substance P, mast cell tryptase, prostaglandin D2 and histamine in induced sputum were measured by ELISA. Cough threshold C2 and C5 did not differ between patients with chronic cough due to non-acid or acid reflux, but the values were significantly lower than those for patients with gastro-oesophageal reflux disease without cough and healthy volunteers. Weakly acidic reflux episodes were obviously more frequent in patients with chronic cough due to non-acid reflux than in the other three groups. Sputum substance P and mast cell tryptase concentrations were remarkably increased in patients with chronic cough, but were similar for those with cough due to non-acid or acid reflux. There were significant inverse correlations between substance P levels and cough threshold C2 or C5 in patients with cough due to non-acid or acid reflux, and between mast cell tryptase levels and cough threshold C2 in patients with cough due to acid reflux. Chronic cough due to non-acid reflux may be related to cough reflex hypersensitivity caused by neurogenic airway inflammation and mast cell activation, in which weakly acidic reflux is possibly a major factor. © 2011 The Authors.

To describe the clinical features of canine gastro-oesophageal reflux disease. A search of our medical records produced 20 dogs with clinical signs attributable to oesophageal disease, hyper-regeneratory oesophagopathy and no other oesophageal disorders. The clinical, endoscopic and histological findings of the dogs were analysed. The 3-year incidence of gastro-oesophageal reflux disease was 0·9% of our referral dog population. Main clinical signs were regurgitation, discomfort or pain (each, 20/20 dogs) and ptyalism (18/20 dogs). Oesophagoscopy showed no (5/20 dogs) or minimal (13/20 dogs) mucosal lesions. In oesophageal mucosal biopsy specimens, there were hyperplastic changes of the basal cell layer (13/20 dogs), stromal papillae (14/20 dogs) and entire epithelium (9/20 dogs). Eleven dogs received omeprazole or pantoprazole and regurgitation and ptyalism improved in eight and pain diminished in six of these dogs within three to six weeks. Our findings suggest that canine gastro-oesophageal reflux disease is a more common clinical problem than hitherto suspected. © 2017 British Small Animal Veterinary Association.

A wide variety of symptoms and diseases of the upper aerodigestive tract are associated to gastro-oesophageal reflux disease (GORD). These disorders comprise a large variety of conditions such as asthma, chronic otitis media and sinusitis, chronic cough, and laryngeal disorders including paroxysmal laryngospasm. Laryngo-pharyngeal reflux disease is an extraoesophageal variant of GORD that can affect the larynx and pharynx. Despite numerous research efforts, the diagnosis of laryngopharyngeal reflux often remains elusive, unproven and controversial, and its treatment is then still empiric. Aim of this paper is to review the current literature on upper aerodigestive tract disorders in relation to pathologic gastro-oesophageal reflux, focusing in particular on the pathophysiology base and results of the surgical treatment of GORD.

In this investigation, the author initially made animal experiments to find out: - if and how the gastro-oesophageal reflux in a cardiac insufficiency caused by cardiomyotomy could be proven quantitatively by scintiscanning as often as wanted and how the course of the arising oesophagitis correlated with the findings of the scintiscanning. For the clinical examinations, he referred to patients complaining the reflux difficulties or patients who had had a Balanced Operation because of a reflux disease. The main concern was to clarify the special characteristics and the reliability of reflux scintiscanning and to compare them to conventional methods of radiological and endoscopic reflux diagnostics.

Ulceration of the oesophageal squamous mucosa (ulcerative oesophagitis) is a pathological manifestation of gastro-oesophageal reflux disease, and is a major risk factor for the development of Barrett's oesophagus. Barrett's oesophagus is characterised by replacement of reflux-damaged oesophageal squamous epithelium with a columnar intestinal-like epithelium. We previously reported discovery of microRNAs that are differentially expressed between oesophageal squamous mucosa and Barrett's oesophagus mucosa. Now, to better understand early steps in the initiation of Barrett's oesophagus, we assessed the expression, location and function of these microRNAs in oesophageal squamous mucosa from individuals with ulcerative oesophagitis. Quantitative real-time PCR was used to compare miR-21, 143, 145, 194, 203, 205 and 215 expression levels in oesophageal mucosa from individuals without pathological gastro-oesophageal reflux to individuals with ulcerative oesophagitis. Correlations between microRNA expression and messenger RNA differentiation markers BMP-4, CK8 and CK14 were analyzed. The cellular localisation of microRNAs within the oesophageal mucosa was determined using in-situ hybridisation. microRNA involvement in proliferation and apoptosis was assessed following transfection of a human squamous oesophageal mucosal cell line (Het-1A). miR-143, miR-145 and miR-205 levels were significantly higher in gastro-oesophageal reflux compared with controls. Elevated miR-143 expression correlated with BMP-4 and CK8 expression, and elevated miR-205 expression correlated negatively with CK14 expression. Endogenous miR-143, miR-145 and miR-205 expression was localised to the basal layer of the oesophageal epithelium. Transfection of miR-143, 145 and 205 mimics into Het-1A cells resulted in increased apoptosis and decreased proliferation. Elevated miR-143, miR-145 and miR-205 expression was observed in oesophageal squamous mucosa of individuals with ulcerative oesophagitis. These mi

Gastro-oesophageal reflux disease (GORD) is on the rise with more than 20% of the western population reporting symptoms and is the most common gastrointestinal disorder in the United States. This increase in GORD is not exactly clear but has been attributed to the increasing prevalence of obesity, changing diet, and perhaps the decreasing prevalence of H. pylori infection. Complications of GORD could be either benign or malignant. Benign complications include erosive oesophagitis, bleeding and peptic strictures. Premalignant and malignant lesions include Barrett's metaplasia, and oesophageal cancer. Management of both the benign and malignant complications can be challenging. With the use of proton-pump inhibitors, peptic strictures (i.e., strictures related to reflux) have significantly declined. Several aspects of Barrett's management remain controversial including the stage in the disease process which needs to be intervened, type of the intervention and surveillance of these lesions to prevent development of high grade dysplasia and oesophageal adenocarcinoma.

Gastro-oesophageal reflux - an important causative factor of severe tooth wear in Prader-Willi syndrome?

Prader-Willi syndrome (PWS) is the most common genetic human obesity syndrome and is characterized by hypotonia, endocrine disturbances, hyperphagia, obesity and mild mental retardation. Oral abnormalities, such as decreased salivary flow rates and extreme tooth wear, have also been described. Studies have shown a significant increase in reflux symptoms in individuals with obstuctive sleep apnoea syndrome and increased BMI, both of which are typical findings in PWS. Gastro-oesophageal reflux disease (GORD) has been identified in some individuals with PWS and is a significant intrinsic factor in dental tooth wear. The aim of this study was therefore to estimate the prevalence of GORD in adults and children and to evaluate a possible correlation between GORD and tooth wear in adults with PWS. They were all registered at the TAKO-centre. Twenty-nine individuals, 17 adults with a mean age of 32.6 years (range 18-48) and 12 children with a mean age of 8.8 years (range 3-17), agreed to undergo 24-hour oesophageal pH monitoring, and 90% of those enrolled managed to complete the examination. Four children and eleven adults were diagnosed with pathological gastro-oesophageal reflux, which is defined as acid exposure (pH less than 4) more than 3.6 or 4.3 percent of the time, respectively. Manometry performed in the adult group showed a pathologically high lower oesophageal sphincter pressure in four of the five individuals who had normal oesophageal pH values (pH under 4 less than 4.3% of the time). The two groups (reflux and non-reflux) were well balanced according to BMI, genotype, tooth grinding and hyposalivation. However, twice as many individuals in the reflux group as in the non-reflux group reported high consumption of acidic foods and drinks. Increased tooth wear was significantly correlated with GORD in the two groups (reflux n=6 and non-reflux n=6). The prevalence of gastro-oesophageal reflux is high in individuals with PWS. Tooth wear was strongly associated with

Optimisation of proton pump inhibitors use may improve reflux symptoms in 20-25% of the patients. Pathological gastro-oesophageal reflux should be documented in a patient with refractory reflux symptoms using upper endoscopy and/or pH testing. While on proton pump inhibitors twice daily, persistent symptoms are not related to gastro-oesophageal refluxdisease(GERD) in 50% of the patients. The new anti-reflux compounds have yet a limited efficacy and side effects that currently limit their development. Copyright © 2012. Published by Elsevier Masson SAS.

Gastro-oesophageal reflux disease and non-asthma lung disease

Directory of Open Access Journals (Sweden)

R. S. Morehead

2009-12-01

Full Text Available Gastro-oesophageal reflux disease (GERD is a common disorder in Western countries, and its relationship to airways disorders (e.g. asthma has been well established. Lung diseases other than asthma have also been associated with GERD, but the nature and scope of this relationship has not been fully defined. Diseases that have been associated with GERD include bronchiolitis syndromes, idiopathic pulmonary fibrosis, scleroderma and nontubercular mycobacterial infection. Diagnostic evaluation centres upon proving both reflux and pulmonary aspiration, which may be accomplished in some cases by lung biopsy. However, in many cases a compatible clinical and radiographic picture coupled with proof of proximal reflux by combined oesophageal probe testing may suffice for a provisional diagnosis and allow institution of anti-reflux measures. Proton-pump inhibitors are the medications of choice for GERD; other interventions shown to reduce reflux are weight loss, elevation of the head of the bed and avoidance of recumbency after meals. However, acid suppression therapy does not address non-acid reflux that may be important in disease pathogenesis in select patients, and lifestyle modifications often fail. Laparoscopic fundoplication is the procedure of choice for medically refractory GERD with excellent short-term results with respect to respiratory symptoms associated with GERD; however, long-term studies document a significant percentage of patients requiring ongoing acid suppression therapy.

An investigation to detect food-stimulated gastro-oesophageal (GE) reflux was carried out in 54 consecutive fasting patients, 35 of whom experienced reflux while 19 did not. All patients then received a standard meal (566 kcal), and the investigation was repeated 1 h afterward. Of the 35 with GE reflux in the fasting state, 33 also had GE reflux in the postprandial state, and 17 of the 19 patients with no GE reflux while fasting also had none in the postprandial state. It is concluded that the radiological method can identify most patients in whom food-stimulated GE reflux could be of clinical significance. (orig.).

Gastro-oesophageal reflux. Part 1: smoking and alcohol reduction.

Al Talalwah, Narmeen; Woodward, Sue

Gastro-oesophageal reflux disease (GORD) is defined as an abnormal reflux of the stomach contents into the oesophagus, which provokes symptoms and impairs the quality of life. GORD has a high prevalence and incurs costs to the healthcare system. This is the first paper in a series of three exploring the conservative, medical and surgical treatment of GORD. This first paper presents a review of the effect of smoking and alcohol on reflux symptoms and the impact of smoking and alcohol reduction on symptoms of GORD. A search for English language studies on adults was conducted using three databases, MEDLINE, Embase and the Cochrane Central Register of Controlled Trials (CENTRAL). Eleven relevant studies were included in the review. The effect of alcohol on the stimulation of reflux has been debated over the years in different studies. Some studies state that alcohol consumption induces reflux and moderate amounts exacerbate nocturnal gastro-oesophageal heartburn reflux. However, other studies have found no association between alcohol consumption and reflux. Most reflux occurs during smoking because nicotine causes the lower oesophageal sphincter to relax, which increases the risk of reflux. Similarly, the number of cigarettes smoked is associated with the risk of reflux. Nurses need to be aware of the effect of smoking and alcohol on reflux to provide evidence-based advice to empower patients to change their lifestyle, which results in increased therapeutic compliance and a better clinical status. There is no evidence that reducing alcohol consumption decreases symptoms and only limited evidence on the effectiveness of smoking cessation. Further research into the effectiveness of these lifestyle modifications is therefore required.

Gastro-oesophageal reflux symptoms are common in the community, but there has been no definitive systematic review and meta-analysis of data from all studies to estimate their global prevalence, or potential risk factors for them. Medline, Embase and Embase Classic were searched (until September 2016) to identify population-based studies that reported the prevalence of gastro-oesophageal reflux symptoms in adults (≥15 years); gastro-oesophageal reflux was defined using symptom-based criteria or questionnaires. The prevalence was extracted for all studies, and according to the criteria used to define it. Pooled prevalence, according to study location and certain other characteristics, OR and 95% CIs were calculated. Of the 14 132 citations evaluated, 102 reported the prevalence of gastro-oesophageal reflux symptoms in 108 separate study populations, containing 460 984 subjects. Prevalence varied according to country (from 2.5% in China to 51.2% in Greece) and criteria used to define gastro-oesophageal reflux symptoms. When only studies using a weekly frequency of heart burn or regurgitation to define presence were considered, pooled prevalence was 13.3% (95% CI 12.0% to 14.6%). Prevalence was higher in subjects ≥50 years (OR 1.32; 95% CI 1.12 to 1.54), smokers (OR 1.26; 95% CI 1.04 to 1.52), non-steroidal anti-inflammatory drug (NSAID)/aspirin users (OR 1.44; 95% CI 1.10 to 1.88) and obese individuals (OR 1.73; 95% CI 1.46 to 2.06). The prevalence of gastro-oesophageal reflux symptoms varied strikingly among countries, even when similar definitions were used to define their presence. Prevalence was significantly higher in subjects ≥50 years, smokers, NSAID users and obese individuals, although these associations were modest. Published by the BMJ Publishing Group Limited.

The diagnosis of gastro-oesophageal reflux disease (GERD) remains a challenge as both invasive methods and symptom-based strategies have limitations. The symptom-based management of GERD in primary care may be further optimised with the use of a questionnaire. To assess the diagnostic validity of the GerdQ questionnaire in patients with symptoms suggestive of GERD. Patients with symptoms suggestive of GERD without alarm features, underwent upper endoscopy, and if normal, pH-metry. Patients were followed for 4 weeks and GerdQ was completed blinded to the investigator at both visits. Reflux oesophagitis or pathological acid exposure was used as diagnostic references for GERD. The diagnostic accuracy for GERD on symptom response to proton pump inhibitor (PPI) was assessed. Among the 169 patients, a GerdQ cutoff ≥9 gave the best balance with regard to sensitivity, 66% (95% CI: 58-74), and specificity, 64% (95% CI: 41-83), for GERD. The high prevalence of reflux oesophagitis (81%) resulted in a high proportion of true positives, but at the same time a high proportion of false-negatives. Consequently, GerdQ had a high positive predictive value, 92% (95% CI: 86-97), but a low negative predictive value, 22% (95% CI: 13-34), for GERD. Symptom resolution on PPI therapy had high sensitivity, 76% (95% CI: 66-84), but low specificity, 33% (95% CI: 17-53), for GERD. GerdQ is a useful complementary tool for the diagnosis of gastro-oesophageal reflux disease in primary care. The implementation of GerdQ could reduce the need for upper endoscopy and improve resource utilisation. Symptom resolution on proton pump inhibitor did not predict gastro-oesophageal reflux disease. © 2013 Blackwell Publishing Ltd.

An association between acid gastro-oesophageal reflux disease (GERD) and Jackhammer oesophagus has been suggested. To assess the prevalence and characteristics of acid-GERD in Jackhammer oesophagus and the efficacy of proton pump inhibitors. Data and outcomes of patients with Jackhammer oesophagus were assessed. Two groups were compared: (i) GERD, defined by endoscopic oesophagitis or by an increase in acid exposure time or by an acid-hypersensitive oesophagus and (ii) non-GERD defined by normal oesophageal acid exposure without acid-hypersensitive oesophagus. Among the 1994 high-resolution manometries performed, 44 Jackhammer oesophagus (2.2%) were included (sex ratio M/F: 19/25; median age: 66 [61-75] years). Nineteen patients (43.2%) had GERD, 16 (36.4%) had no GERD and 9 patients (20.4%) were undetermined. Dysphagia was the predominant symptom (37/43 (86%)). After a median follow-up of 25.3 months [9.6-31.4], dysphagia was improved in 22/36 (61.1%) patients. Dysphagia improvement as well as other symptoms improvement was not associated with GERD status or proton-pump inhibitors use. The prevalence of GERD is high among patients with Jackhammer oesophagus. The rates of symptom improvement in Jackhammer oesophagus were high regardless of the use of proton-pump inhibitors treatment or of the presence of GERD.

The origin and significance of cardiac mucosa at the gastro-oesophageal junction are controversial. In the prospective Central European multicentre histoGERD trial, we aimed to assess the prevalence of cardiac mucosa, characterized by the presence of glands composed of mucous cells without parietal cells, and to relate its presence to features related to gastro-oesophageal reflux disease (GORD). One thousand and seventy-one individuals (576 females and 495 males; median age 53 years) were available for analysis. Overall, in biopsy specimens systematically taken from above and below the gastro-oesophageal junction, cardiac mucosa was observed in 713 (66.6%) individuals. Its presence was associated with patients' symptoms and/or complaints (P = 0.0025), histological changes of the squamous epithelium (P gastro-oesophageal junction. Its association with reflux symptoms, histological changes indicating GORD and the endoscopic diagnosis of oesophagitis suggests that injury and repair related to GORD contribute to its development and/or expansion. © 2014 John Wiley & Sons Ltd.

Gastro-oesophageal reflux is very common in the paediatric age group. There is no single and reliable test to distinguish between physiologic and pathological gastro-oesophageal reflux, and this lack of clear distinction between disease and normal can have a negative impact on the management of children. To evaluate the usefulness of 24-h oesophageal pH-impedance study in infants and children with suspected gastro-oesophageal reflux disease. Patients were classified by age groups (A-C) and reflux-related symptoms (typical and atypical). All underwent pH-impedance study. If the latter suggested an abnormal reflux, patients received therapy in accordance with NASPGHAN/ESPGHAN recommendations, while those with normal study had an additional diagnostic work-up. The efficacy of therapy was evaluated with a specific standardized questionnaire for different ages. The study was abnormal in 203/428 patients (47%) while normal in 225/428 (53%). Of those with abnormal study, 109 exhibited typical symptoms (54%), and 94 atypical (46%). The great majority of the patients with abnormal study were responsive to medical anti-reflux therapy. We confirm the utility of prolonged oesophageal pH-impedance study in detecting gastro-oesophageal reflux disease in children and in guiding therapy. Performing oesophageal pH-impedance monitoring in children with suspected gastro-oesophageal reflux disease is helpful to establish the diagnosis and avoid unnecessary therapy.

The diagnostic corroboration of the relationship between gastro-oesophageal reflux disease (GERD) and chronic cough remains challenging. To compare oesophageal mucosal intercellular space diameter (ISD) in children with GERD, children with gastro-oesophageal reflux (GER)-related cough (GrC) and a control group, and to explore the relationship between baseline impedance levels and dilated ISD in children with GER-related cough. Forty children with GERD, 15 children with GrC and 12 controls prospectively underwent oesophagogastroduodenoscopy (EGD) with oesophageal biopsies taken 2-3 cm above squamocolumnar junction. ISD were quantified using transmission electron microscopy. Impedance-pH monitoring with evaluation of baseline impedance in the most distal impedance channel was performed in both patient groups. A significant difference in mean ISD values was found between GrC patients (0.9 ± 0.2 μm) and controls (0.5 ± 0.2 μm, P reflux parameter. Finally, there was no correlation between ISD and distal baseline impedance values (r:-0.35; NS). In children with reflux-related cough, dilated intercellular space diameter appears to be an objective and useful marker of oesophageal mucosal injury regardless of acid exposure, and its evaluation should be considered for those patients where the diagnosis is uncertain. In children with reflux-related cough, baseline impedance levels have no role in identifying reflux-induced oesophageal mucosal ultrastructural changes. © 2014 John Wiley & Sons Ltd.

Background and aims: Approximately 10% of adults experience gastro-oesophageal reflux symptoms with a variable oesophageal response. A total of 60% have no endoscopic abnormality, 30% have oesophagitis, and 10% have Barrett's oesophagus. We investigated whether the inflammatory cell infiltrate and cytokine profiles of these clinical phenotypes merely vary in severity or are fundamentally different. Methods: Patients with reflux symptoms and a normal oesophagus (n=18), oesophagitis (n=26), and Barrett's oesophagus (n=22 newly diagnosed, n=28 surveillance) were recruited. Endoscopic and histopathological degrees of inflammation were scored. Cytokine expression was determined by competitive reverse transcriptase-polymerase chain reaction and immunohistochemistry. Results: In oesophagitis, endoscopic and histopathological grades of inflammation correlated highly. mRNA expression of proinflammatory interleukin (IL)-1β, IL-8, and interferon γ (IFN-γ) were increased 3–10-fold compared with non-inflamed squamous or Barrett's oesophageal samples. There was a modest increase in anti-inflammatory IL-10 but no increase in IL-4. In Barrett's oesophagus, 29/50 had no endoscopic evidence of inflammation and histopathological inflammation was mild in 17/50 and moderate in 24/50, independent of acid suppressants. Expression of IL-1β, IL-8, and IFN-γ was similar to non-inflamed squamous mucosa. IL-10 was increased 1.6-fold similar to oesophagitis. IL-4 was increased fourfold, with 100-fold increase in IL-4/T cell receptor expression, compared with squamous oesophagus or oesophagitis. Conclusions: Barrett's oesophagus is characterised by a distinct Th-2 predominant cytokine profile compared with the proinflammatory nature of oesophagitis. The specific oesophageal immune responses may influence disease development and progression. PMID:11889061

Gastro-oesophageal reflux in young babies: who should be treated?

Science.gov (United States)

Puntis, John W

2015-10-01

Recent guidelines focus on a non-interventionist approach to management of gastro-oesophageal reflux in infancy and emphasise the importance of explanation, reassurance and simple measures such as attention to feeding. Relying on clinical history alone leads to over diagnosis of disease, and widely used medications are often ineffective for symptom relief and carry significant risk of harm. The association between vomiting in infancy and other problems such as crying and poor feeding should not be interpreted as implying causality. When there are strong pointers to underlying gastro-oesophageal reflux disease, invasive investigations are required in order to formulate appropriate intervention.

2006-12-01

Full Text Available Abstract Background Several studies have reported an association between asthma and gastro-oesophageal reflux, but it is unclear which condition develops first. The role of obesity in mediating this association is also unclear. We explored the associations between respiratory symptoms, lung function, and gastro-oesophageal reflux symptoms in a birth cohort of approximately 1000 individuals. Methods Information on respiratory symptoms, asthma, atopy, lung function and airway responsiveness was obtained at multiple assessments from childhood to adulthood in an unselected birth cohort of 1037 individuals followed to age 26. Symptoms of gastro-oesophageal reflux and irritable bowel syndrome were recorded at age 26. Results Heartburn and acid regurgitation symptoms that were at least "moderately bothersome" at age 26 were significantly associated with asthma (odds ratio = 3.2; 95% confidence interval = 1.6–6.4, wheeze (OR = 3.5; 95% CI = 1.7–7.2, and nocturnal cough (OR = 4.3; 95% CI = 2.1–8.7 independently of body mass index. In women reflux symptoms were also associated with airflow obstruction and a bronchodilator response to salbutamol. Persistent wheezing since childhood, persistence of asthma since teenage years, and airway hyperresponsiveness since age 11 were associated with a significantly increased risk of heartburn and acid regurgitation at age 26. There was no association between irritable bowel syndrome and respiratory symptoms. Conclusion Reflux symptoms are associated with respiratory symptoms in young adults independently of body mass index. The mechanism of these associations remains unclear.

To determine whether a pH probe or multichannel intraluminal impedance (MII) more frequently detected gastro-oesophageal reflux and test the hypothesis that acid reflux was associated with lower baseline impedance. A prospective study of infants in whom reflux was suspected and evaluated using combined pH and multichannel impedance. Studies were considered abnormal if the acid index was >10% or there were >79MII reflux events in 24 hours. The acid index was the percentage of total study time with a pHacid clearance time (ACT) the time from the pH falling below four to rising above four. Forty-two infants [median gestational age 31 (range 23-42) weeks] were assessed. Only nine infants (21%) had abnormal studies, seven detected by pH monitoring, one by MII monitoring and one by both techniques (p = 0.04). After correcting for gestational age and post-natal age, baseline impedance remained negatively correlated with the acid index (r = -0.34, p = 0.038) and the maximum ACT (r = -0.44, p = 0.006). Clinical suspicion of reflux was frequently incorrect, and reflux was more frequently detected by a pH probe. The inverse relationship of acid reflux to baseline impedance suggests that mucosal disruption may result from acid reflux in this population. ©2018 Foundation Acta Paediatrica.

Extra-oesophageal symptoms of gastro-oesophageal reflux disease (GORD) are often studied, but remain a subject of debate. It has been clearly shown that there is a relationship between the extra-oesophageal symptoms chronic cough, asthma, laryngitis and dental erosion and GORD. Literature is abundant concerning reflux-related cough and reflux-related asthma, but much less is known about reflux-related dental erosions. The prevalence of dental erosion in GORD and vice versa, the prevalence of GORD in patients with dental erosion is high but the exact mechanism of reflux-induced tooth wear erosion is still under review.

Fifty one infants and older children with suspected gastro-oesophageal reflux entered a study comparing the diagnostic accuracy of a standard barium swallow examination with that of ultrasound scanning. All children were examined by both techniques. In 40 cases there was unequivocal agreement between the examinations. Of the remaining patients, four had definite reflux by ultrasonic criteria but showed no evidence of reflux on barium swallow examination, four had positive findings on ultrasound but showed only minimal reflux on barium swallow, and one showed minimal reflux on ultrasound but had a negative barium meal result. In two children the ultrasound study was inconclusive. Ultrasound has an important role in the diagnosis and follow up of patients under the age of 5 years with gastro-oesophageal reflux.

There is a general belief that gastro-oesophageal reflux increases after meals and especially following a rapid intake. To evaluate the impact of rapid vs. slow food intake on gastro-oesophageal reflux disease (GORD) patients. Forty-six GORD patients with heartburn and / or acid regurgitation once a week or more often common were included in this study. Participants were asked to eat the same standard meal within either 5 or 30 minutes under observation in a random order on 2 consecutive days. A total of 28 hours of recording were obtained by intraoesophageal impedance pH and number of liquid and mixed reflux episodes within 3 hours of the slow- and fast-eating postprandial periods were calculated. While all patients defined GORD symptoms, 10 (21.7%) had pathological 24-h intraoesophageal impedance measurement, 15 (32.6%) had pathological DeMeester and 21.7% had erosive oesophagitis. No difference has been shown according to the eating speed when all reflux episodes were taken together (754 vs. 733). Speed of food intake also did not have an impact on patients with normal vs. pathological 24-h intraoesophageal impedance or erosive vs. non-erosive. During the first postprandial hour, approximately half of the reflux events were non-acid, compared to 34.2% during the second hour and 26.8% during the third hour (p reflux episodes was significantly higher than non-acid reflux especially during the second and third hours and in total for 3 hours. This first study addressing the effect of eating speed on reflux episodes in GORD patients did not support the general belief that reflux increases following fast eating. Acid and non-acid reflux were similar at the first postprandial hour, then acid reflux episodes were predominantly higher, which implicate the importance of acid pockets.

Laparoscopic sleeve gastrectomy is a safe and effective bariatric operation, but postoperative reflux symptoms can sometimes necessitate revisional surgery. Roux-en-Y gastric bypass is the preferred operation in morbidly obese patients with gastro-oesophageal reflux disease. In 2011, we introduced preoperative endoscopy to assess for hiatus hernia or evidence of oesophagitis in conjunction with an assessment of gastro-oesophageal reflux symptoms for all patients undergoing bariatric surgery with a view to avoid sleeve gastrectomy for these patients. A prospectively maintained database was used to identify patients who underwent sleeve gastrectomy before and after we changed the unit policy. The need for revisional surgery in patients with troublesome gastro-oesophageal reflux disease was examined. Prior to 2011, 130 patients underwent sleeve gastrectomy, and 11 (8.5%) of them required conversion to Roux-en-Y gastric bypass for symptomatic reflux disease. Following the policy change, 284 patients underwent sleeve gastrectomy, and to date, only five (1.8%) have required revisional surgery (p = 0.001). Baseline demographics were comparable between the groups, and average follow-up period was 47 and 33 months, respectively, for each group. Preoperative endoscopy and a detailed clinical history regarding gastro-oesophageal reflux symptoms may improve patient selection for sleeve gastrectomy. Avoiding sleeve gastrectomy in patients with reflux disease and/or hiatus hernia may reduce the incidence of revisional surgery. © 2016 World Obesity.

Objectives To investigate the effects of Helicobacter pylori infection and its eradication on heartburn and gastro-oesophageal reflux. Design Cross sectional study, followed by a randomised placebo controlled trial. Setting Seven general practices in Bristol, England. Participants 10 537 people, aged 20-59 years, with and without H pylori infection (determined by the 13C-urea breath test). Main outcome measures Prevalence of heartburn and gastro-oesophageal acid reflux at baseline and two years after treatment to eradicate H pylori infection. Results At baseline, H pylori infection was associated with increased prevalence of heartburn (odds ratio 1.14, 95% confidence interval 1.05 to 1.23) but not reflux (1.05, 0.97 to 1.14). In participants with H pylori infection, active treatment had no effect on the overall prevalence of heartburn (0.99, 0.88 to 1.12) or reflux (1.04, 0.91 to 1.19) and did not improve pre-existing symptoms of heartburn or reflux. Conclusions H pylori infection is associated with a slightly increased prevalence of heartburn but not reflux. Treatment to eradicate H pylori has no net benefit in patients with heartburn or gastro-oesophageal reflux. PMID:15126313

Epidemiology and natural history of gastro-oesophageal reflux disease.

Spechler, S J

1992-01-01

Epidemiological studies of gastro-oesophageal reflux disease (GORD) are confounded by the lack of a standardized definition and a diagnostic 'gold-standard' for the disorder. In Western countries, 20-40% of the adult population experience heartburn, which is the cardinal symptom of GORD, but only some 2% of adults have objective evidence of reflux oesophagitis. The incidence of GORD increases with age, rising dramatically after 40 years of age. There is also wide geographical variation in prevalence. Complications, including oesophageal ulcer and stricture, and Barrett's oesophagus, are found in up to 20% of patients with verified reflux oesophagitis. The signs and symptoms of GORD often wax and wane in intensity, and spontaneous remissions have been reported. In most cases, however, GORD is a chronic condition that returns shortly after discontinuing therapy. Although GORD causes substantial morbidity, the annual mortality rate due to GORD is very low (approximately 1 death per 100,000 patients), and even severe GORD has no apparent effect on longevity, although the quality of life can be significantly impaired. There are data to suggest that the use of non-steroidal anti-inflammatory drugs (NSAIDs) contributes to oesophagitis and stricture formation in patients with GORD. Although these data are not conclusive, it seems prudent, if possible, to avoid the use of NSAIDs in patients with GORD, particularly those with oesophageal stricture.

Gastro-oesophageal reflux symptoms are usually reported by patients with obesity and metabolic syndrome. Aim of this study was to assess the prevalence and clinical characteristics of gastro-oesophageal reflux symptoms in subjects with non-alcoholic fatty liver disease. Cross-sectional, case-control study of 185 consecutive patients with non-alcoholic fatty liver disease and an age- and sex-matched control group of 112 healthy volunteers. Participants were interviewed with the aid of a previously validated questionnaire to assess lifestyle and reflux symptoms in the 3 months preceding enrolment. Odds ratios were determined before and after adjustment for body mass index, increased waist circumference, physical activity, metabolic syndrome and proton pump inhibitors and/or antiacid medication. The prevalence of heartburn and/or regurgitation and of at least one of gastro-oesophageal reflux symptoms was significantly higher in the non-alcoholic fatty liver disease group. Non-alcoholic fatty liver disease subjects were associated to higher prevalence of heartburn (adjusted odds ratios: 2.17, 95% confidence intervals: 1.16-4.04), regurgitation (adjusted odds ratios: 2.61, 95% confidence intervals: 1.24-5.48) and belching (adjusted odds ratios: 2.01, 95% confidence intervals: 1.12-3.59) and had higher prevalence of at least one GER symptom (adjusted odds ratios: 3.34, 95% confidence intervals: 1.76-6.36). Non-alcoholic fatty liver disease is associated with a higher prevalence of gastro-oesophageal reflux symptoms. Copyright © 2012 Editrice Gastroenterologica Italiana S.r.l. Published by Elsevier Ltd.

Niimi, Akio

2017-12-01

Differences in the aetiology as well as patient background of chronic cough have been recognised among US, UK, and Japan. One of the marked differences has been the prevalence of gastro-oesophageal reflux disease (GORD), which has been one of the top three causes in Western countries. It was indeed uncommon or rare in Japan, but, with the increasing prevalence of GOR itself, chronic cough associated with GORD seems to have become more common. In this article, cough associated with GORD will be reviewed based on literature and our Japanese experience. Further, potentially broader relevance of GORD in chronic cough will also be mentioned, highlighting the potential importance of dysmotiliy/non-acid reflux. Copyright © 2017 Elsevier Ltd.

Gastro-oesophageal reflux and dyspepsia are felt to be separate upper gastrointestinal (GI) conditions. We aimed to measure the degree of overlap between them, and assess whether endoscopic findings differed. Demographic, symptom, upper GI endoscopy and histology data were collected from consecutive adults in secondary care. Patients were categorised according to whether they reported gastro-oesophageal reflux alone, dyspepsia alone or both, and patient demographics and endoscopic findings were compared. Of 1167 patients, 97 (8.3%) had gastro-oesophageal reflux alone, 571 (48.9%) dyspepsia alone, and 499 (42.8%) overlap. Patients with overlap symptoms were more likely to smoke, compared with those with gastro-oesophageal reflux alone, or dyspepsia alone (p = .009), but there were no other differences. Patients with gastro-oesophageal reflux alone or overlap had a higher prevalence of erosive oesophagitis (18.6% and 15.4% respectively, p Gastro-oesophageal reflux and dyspepsia symptoms commonly overlap. There were minimal differences in demographics or spectrum of underlying organic disease between various symptom groups, suggesting that restrictive classifications according to predominant symptom may not be clinically useful.

Respiratory manifestations of gastro-oesophageal reflux in children.

de Benedictis, Fernando Maria; Bush, Andrew

2018-03-01

Gastro-oesophageal reflux disease (GORD) is a complex problem in children. Suspected respiratory manifestations of GORD, such as asthma, chronic cough and laryngitis, are commonly encountered in the paediatric practice, but continue to be entities with more questions than answers. The accuracy of diagnostic tests (ie, pH or pH-impedance monitoring, laryngoscopy, endoscopy) for patients with suspected extraoesophageal manifestations of GORD is suboptimal and therefore whether there is a causal relationship between these conditions remains largely undetermined. An empiric trial of proton pump inhibitors can help individual children with undiagnosed respiratory symptoms and suspicion of GORD, but the response to therapy is unpredictable, and in any case what may be being observed is spontaneous improvement. Furthermore, the safety of these agents has been called into question. Poor response to antireflux therapy is an important trigger to search for non-gastro-oesophageal reflux causes for patients' symptoms. Evidence for the assessment of children with suspected extraoesophageal manifestations of GORD is scanty and longitudinal studies with long-term follow-up are urgently required. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Gastro-oesophageal reflux disease (GORD) and morbid obesity are entities with increasing prevalence. New clinical strategies are cornerstones for their management. The aim of this study was to assess the prevalence of heartburn during sleep (HDS) and whether this symptom predicts the presence of objective GORD parameters and increased heartburn perception in morbidly obese patients. Ninety-one consecutive morbidly obese patients underwent clinical evaluation, upper gastrointestinal endoscopy and oesophageal pH monitoring. HDS was characterized when patients replied positively to the question, 'Does heartburn wake you from sleep?'. A General Score for Heartburn (GSH) ranging between 0 and 5 was assessed with the question 'How bad is your heartburn?'. HDS was reported by 33 patients (36%). More patients with HDS had abnormal acid contact time or reflux oesophagitis than patients without HDS (94%vs 57%, P heartburn preceded by acid reflux in diurnal (39%vs 9%; P heartburn. HDS occurs in a significant minority of patients with morbid obesity and has high positive predictive value for GORD. Symptomatic reflux during the sleep seems to be a marker of increased heartburn perception in this population.

Dental erosion is a complication of gastro-oesophageal reflux disease (GORD) according to the Montreal consensus statement. However, GORD has not been comprehensively characterized in patients with dental erosions and pH-impedance measures have not been reported. Characterize GORD in patients with dental erosions using 24-h multichannel intraluminal pH-impedance measurements (pH-MII) and endoscopy. This single-centre study investigated reflux in successive patients presenting to dentists with dental erosion using pH-MII and endoscopy. Of the 374 patients, 298 (80%) reported GORD symptoms reflux episodes were 71 (63-79), 43 (38-49) and 31 (26-35), respectively. Of the reflux episodes, 19% (17-21) reached the proximal oesophagus. In 241 (69%) patients reflux was abnormal using published normal values for acid exposure time and reflux episodes. No significant associations between the severity of dental erosions and any reflux variables were found. The presence of GORD symptoms and of oesophagitis or a hiatal hernia was associated with greater reflux, but not with increased dental erosion scores. Significant oligosymptomatic gastro-oesophageal reflux occurs in the majority of patients with dental erosion. The degree of dental erosion did not correlate with any of the accepted quantitative reflux indicators. Definition of clinically relevant reflux parameters by pH-MII for dental erosion and of treatment guidelines are outstanding. Gastroenterologists and dentists need to be aware of the widely prevalent association between dental erosion and atypical GORD.

To compare the effect of anti-reflux surgery (ARS) versus proton pump inhibitor therapy on lower oesophageal sphincter (LOS) function and oesophageal acid exposure in patients with chronic gastro-oesophageal reflux disease (GORD) over a decade of follow-up. In this randomised, prospective, multicentre study we compared LOS pressure profiles, as well as oesophageal exposure to acid, at baseline and at 1 and 10 years after randomisation to either open ARS (n = 137) or long-term treatment with omeprazole (OME) 20-60 mg daily (n = 108). Median LOS resting pressure and abdominal length increased significantly and remained elevated in patients operated on with ARS, as opposed to those on OME. The proportion of total time (%) with oesophageal pH acid exposure was normalised in both groups, with no significant differences, and bilirubin exposure was within normal limits. After 10 years, patients with or without Barrett's oesophagus did not differ in acid reflux control between the two treatment options. Open ARS and OME were both effective in normalising acid reflux into the oesophagus even when studied over a period of 10 years. Anatomically and functionally the LOS was repaired durably by surgery, with increased resting pressure and abdominal length.

Radiologic diagnosis of gastro-oesophageal reflux. Comparison of barium and low-density contrast medium

Energy Technology Data Exchange (ETDEWEB)

Fransson, S.G.; Soekjer, H.; Johansson, K.E.; Tibbling, L.

It has been proposed that the high density of ordinary barium suspension may complicate the radiologic diagnosis of gastro-oesophageal reflux. For this reason P-contrast was developed (Ferring AB); a contrast medium with the same density as water (1 g/cm/sup 3/). A comparison of P-contrast and barium (Mixobar Ventrikel 400 mg/ml) was performed in 82 patients. All patients were examined with both contrast media and the findings were compared with those at reflux test at manometry, endoscopy and 24-hour pH monitoring. Another 40 patients and 15 symptom-free controls were examined with two different amounts of barium, 100 ml and 200 ml, to study if the radiologic diagnosis of reflux varied with the volume of contrast medium administered. P-contrast was found to have no advantages over barium for the diagnosis of gastro-oesophageal reflux. The outcome of the radiologic examination was not influenced by the different volumes of barium used.

Symptomatically 'silent' gastro-oesophageal reflux disease (GORD) may be underdiagnosed. To determine the prevalence of untreated GORD without heartburn and/or regurgitation in primary care. Patients were included if they had frequent upper gastrointestinal symptoms and had not taken a proton pump inhibitor in the previous 2 months (Diamond study: NCT00291746). GORD was diagnosed based on the presence of reflux oesophagitis, pathological oesophageal acid exposure, and/or a positive symptom-acid association probability. Patients completed the Reflux Disease Questionnaire (RDQ) and were interviewed by physicians using a prespecified symptom checklist. GORD was diagnosed in 197 of 336 patients investigated. Heartburn and/or regurgitation were reported in 84.3% of patients with GORD during the physician interviews and in 93.4% of patients with GORD when using the RDQ. Of patients with heartburn and/or regurgitation not identified at physician interview, 58.1% (18/31) reported them at a 'troublesome' frequency and severity on the RDQ. Nine patients with GORD did not report heartburn or regurgitation either at interview or on the RDQ. Structured patient-completed questionnaires may help to identify patients with GORD not identified during physician interview. In a small proportion of consulting patients, heartburn and regurgitation may not be present in those with GORD.

Review article: gastro-oesophageal reflux disease in asthma and chronic obstructive pulmonary disease.

When gastro-oesophageal reflux is causing symptoms or lesions in the oesophagus, this is referred to as gastro-oesophageal reflux disease (GERD). GERD can manifest itself through typical symptoms (heartburn, regurgitation) or may lead to extra-oesophageal symptoms. Extra-oesophageal manifestations of GERD gained increasing attention over the last decade, especially respiratory disorders, because of the prevalent co-occurrence with GERD. The role of GERD in the pathogenesis of respiratory disorders has become a topic of intense discussion. To provide an overview of the current knowledge on the role of GERD in asthma and chronic obstructive pulmonary disease (COPD). PubMed was searched for relevant articles using the keywords: GERD, asthma, COPD, prevalence, treatment. Case reports were excluded, only English language articles were considered. Estimates for the prevalence of GERD in asthma range from 30% to 90%, compared to an average of 24% in controls. In COPD patients, the prevalence of GERD ranges from 19% to 78% compared to an average of 18% in controls. These data indicate an increased prevalence of GERD in patients with asthma and COPD, although causality is not established and GERD treatment yielded inconsistent effects. Literature supports GERD as a risk factor for COPD-exacerbations and a predictor of the 'frequent-exacerbator'-phenotype. Despite the high prevalence of GERD in asthma and COPD, a causal link is lacking. The results of anti-reflux therapy on pulmonary outcome are inconsistent and contradictory.

A method is presented which combines gastro-oesophageal reflux quantification and oesophageal activity. A group of 33 subjects with gastro-oesophageal reflux symptoms and endoscopically confirmed reflux oesophagitis and a group of 21 asymptomatic subjects with normal oesophageal, gastric and duodenal endoscopic findings were examined. The subjects were given 37 MBq {sup 99m}Tc-Sn-colloid in saline orally and then scintiscanned dynamically. The gastro-oesophageal quantification was done after transit measurement and after the oesophageal time activity (to detect residual oesophageal activity) reached its minimum. The difference in the reflux indices between the two groups was highly significant. In low-grade oesophagitis measured reflux was lower than in higher grades of disease. Only 4.7% false-positive results were observed with a specificity of 95%, indicating that this method may be superior to methods published earlier. (orig.).

The objective of the present study was to determine if there is correlation between signs of reflux laryngitis (RL) and reflux oesophagitis (RE) in patients with gastro-oesophageal reflux disease (GORD) symptoms. Laryngeal photography obtained from patients during oesophagogastroduodenoscopy were examined by two otolaryngologists experienced in the field of extra-oesophageal reflux regarding the presence and severity of RL. The presence of RE was evaluated by gastroenterologist. Smokers, heavy drinkers and patients with bronchial asthma were excluded from the statistical analysis. A total of 681 patients were analysed. RL was diagnosed in 367 (53.9%) cases, of whom 182 patients had mild, 118 moderate and 67 severe (Reflux Finding Score > 7) RL. RE was diagnosed in 103 (28.1%) patients with RL and in 80 (25.7%) patients without RL. Neither the difference between the overall group of patients with RL and those without (OR 1.141, 95% CI 0.811-1.605, p = 0.448), nor the differences between the respective subgroups of patients with mild, moderate and severe RL and those without RL were statistically significant. The OR and 95% CI for mild, moderate and severe RL were 1.042, 95% CI 0.712-1.526, p = 0.834, 1.182, 95% CI 0.764-1.831, p = 0.453 and 1.0, 95% CI 0.566-1.766, p = 0.999 respectively. It can be concluded that there is no correlation between RL and RE in patients with GORD symptoms. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale, Rome, Italy.

To determine the influence of modern airway clearance techniques using assisted autogenic drainage (AAD), whether or not combined with bouncing, on acid gastro-oesophageal reflux (GOR) in infants reflux episodes (RE) and the refluxindex (RI) were the outcome measures. The results obtained during (T15) and 15 min after the intervention (T30) were compared to a period of 15 min before treatment (T0). The results of 150 infants, evenly distributed over the three treatment groups, were analyzed. No significant differences were found in number of RE at T15 and T30 compared to T0 in the bouncing group (P = 0.42), the AAD group (P = 0.14), and the BAAD group (P = 0.91). RI was significantly lower in the AAD group at T15 compared to T0 (P < 0.01). No differences in RI were found in the bouncing group (P = 0.28), nor in the BAAD group (P = 0.81). Bouncing, AAD and BAAD do not induce, nor aggravate acid GOR in infants under the age of 1 year. © 2017 Wiley Periodicals, Inc.

The detection of gastro-oesophageal reflux in varicose changes of the oesophagus using scintigraphy. Szintigraphischer Nachweis des gastro-oesophagealen Refluxes bei Patienten mit Oesophagusvarizen

Energy Technology Data Exchange (ETDEWEB)

Kielmann, U.

1984-08-27

Comparative studies carried out in 22 bearers of oesophageal varices and 13 asymptomatic healthy volunteers on the basis of gastric reflux scintigraphy revealed findings to prove the occurrence of physiological reflux for the control group and, by contrast with this observation, markedly prolonged reflux episodes in the patient group. The occurrence of reflux was seen to be linked to the size of the varices found in the terminal oesophagus (negative correlation). A positive and significant correlation could be established between the size of a patient's varices and the frequency of haemorrhages. Bleedings and reflux episodes, however, were observed to be quite unrelated events. The results obtained strongly suggested that gastro-oesophageal reflux cannot be regarded as having a key role in haemorrhages from oesophageal varices. Nor was it possible to find statistical support for the effects of sclerotherapy on the frequency of haemorrhages. This was evidence in confirmation of the fact that obliteration is the obvious method in the treatment of haemorrhaging varices of the oesophagus. (TRV).

Several studies showed high prevalence of ineffective oesophageal motility (IOM) in gastro-oesophageal reflux disease (GERD) and suggested an important role for ineffective oesophageal motility in increased acid exposure. However, impedance-manometric studies proposed that only severe ineffective oesophageal motility might affect oesophageal clearance. (i) To re-assess the relevance of mild IOM in GERD and (ii) to test the reversibility of IOM. Oesophageal motility, clearance and acid exposure were assessed in 191 GERD patients: 99 without IOM; 58 with mild IOM (30-80% ineffective contractions) and 34 with severe IOM (>80% ineffective contractions). In 30 patients with oesophagitis, the potential reversibility of IOM was evaluated with edrophonium intravenously. Patients with mild IOM had identical oesophageal clearance and acid exposure in comparison with those without IOM. Patients with severe IOM had a higher probability of prolonged supine clearance and acid exposure [odds ratio: 2.88 (1.16-7.17); 2.48 (0.99-6.17)]. This effect was independent of the presence of hiatal hernia and male sex. Severe IOM could be transiently reverted in 55% of patients. Mild IOM does not affect oesophageal clearance. Only severe IOM is associated with prolonged clearance and acid exposure, particularly in supine periods. The edrophonium test might be useful to predict severe IOM response to prokinetic medications.

Background Endoscopic screening has been proposed for patients with symptoms of gastro-oesophageal reflux disease (GERD) in the hope of reducing mortality from oesophageal adenocarcinoma. Assessing the net benefits of such a strategy requires a precise understanding of the cancer risk in the screened population. Aim To estimate precisely the association between symptoms of GERD and oesophageal adenocarcinoma. Methods Systematic review and meta-analysis of population-based studies with strict ascertainment of exposure and outcomes. Results Five eligible studies were identified. At least weekly symptoms of GERD increased the odds of oesophageal adenocarcinoma fivefold (odds ratio = 4.92; 95% confidence interval = 3.90, 6.22), and daily symptoms increased the odds sevenfold (random effects summary odds ratio = 7.40, 95% confidence interval = 4.94, 11.1), each compared with individuals without symptoms or less frequent symptoms. Duration of symptoms was also associated with oesophageal adenocarcinoma, but with very heterogeneous results, and unclear thresholds. Conclusions Frequent GERD symptoms are strongly associated with oesophageal adenocarcinoma. These results should be useful in developing epidemiological models of the development of oesophageal adenocarcinoma, and in models of interventions aimed at reducing mortality from this cancer.

Since the publication of the Asia-Pacific consensus on gastro-oesophageal reflux disease in 2008, there has been further scientific advancement in this field. This updated consensus focuses on proton pump inhibitor-refractory reflux disease and Barrett's oesophagus. A steering committee identified three areas to address: (1) burden of disease and diagnosis of reflux disease; (2) proton pump inhibitor-refractory reflux disease; (3) Barrett's oesophagus. Three working groups formulated draft statements with supporting evidence. Discussions were done via email before a final face-to-face discussion. We used a Delphi consensus process, with a 70% agreement threshold, using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria to categorise the quality of evidence and strength of recommendations. A total of 32 statements were proposed and 31 were accepted by consensus. A rise in the prevalence rates of gastro-oesophageal reflux disease in Asia was noted, with the majority being non-erosive reflux disease. Overweight and obesity contributed to the rise. Proton pump inhibitor-refractory reflux disease was recognised to be common. A distinction was made between refractory symptoms and refractory reflux disease, with clarification of the roles of endoscopy and functional testing summarised in two algorithms. The definition of Barrett's oesophagus was revised such that a minimum length of 1 cm was required and the presence of intestinal metaplasia no longer necessary. We recommended the use of standardised endoscopic reporting and advocated endoscopic therapy for confirmed dysplasia and early cancer. These guidelines standardise the management of patients with refractory gastro-oesophageal reflux disease and Barrett's oesophagus in the Asia-Pacific region.

Gastro-oesophageal reflux (GOR) and apnoea are common in infants; whether there is a causal relationship is controversial. To determine whether there was a temporal relationship between GOR and apnoea, in particular, the frequency of obstructive apnoeas and if the frequency of GOR episodes correlated with apnoea frequency when maturity at testing was taken into account. Polysomnography and pH/multichannel intraluminal impedance (MII) studies were performed. Apnoeas were classified as central, obstructive, or mixed. MII events were classified as acidic (pH reflux event was compared to that in the 5-min period preceding the event and that in a 5-min reflux-free period (control period). Forty infants (median gestational age 29 [range 24-42] weeks) were assessed at a post-conceptional age of 37 (30-54) weeks. Obstructive (n = 580), central (n = 900), and mixed (n = 452) apnoeas were identified; 381 acid reflux events were detected by MII and 153 by the pH probe only. Apnoeas were not more frequent following GOR than during control periods. Both the frequency of apnoeas (p = 0.002) and GOR episodes (p = 0.01) were inversely related to post-conceptional age at testing, but were not significantly correlated with each other when controlled for post-conceptional age. These results suggest that GOR does not cause apnoea. © 2017 S. Karger AG, Basel.

Purpose: Gastro-oesophageal reflux (GOR) is demonstrated by radiography as a supplement to 24-h pH monitoring. Material and Methods: Forty-two patients (mean age 44 years) with suspicion of GOR disease were assessed according to a standard questionnaire. GOR was investigated by 24-h pH-monitoring and by radiography. Oesophageal emptying and the presence of rings or strictures were registered as well. Mucosal biopsies, classified as normal, light oesophagitis, severe oesophagitis, or Barrett's oesophagus, were correlated to age, gender, symptomatology, pH monitoring, and oesophageal emptying. GOR and morphological changes demonstrated by radiography were correlated to pH monitoring and mucosa biopsies. Results: Based on pH monitoring, patients with severe oesophagitis and Barrett's oesophagus had a significantly higher acid exposure compared to patients with normal mucosa and light oesophagitis, with no difference concerning age, gender, and symptoms. Severe oesophagitis, including Barrett's oesophagus, was found only in patients with a positive test for radiologic GOR. Eleven patients had rings or strictures independent of oesophageal mucosal changes. Conclusion: GOR demonstrated by radiography identified patients where complications could be expected, which was not possible by pH monitoring alone.

The diagnosis of gastro-oesophageal reflux disease (GERD) in clinical practice is limited by the sensitivity and specificity of symptoms and diagnostic testing. To determine if adding histology as a criterion and excluding patients with epigastric pain enhances the diagnosis for GERD. Patients with frequent upper gastrointestinal symptoms who had not taken a proton pump inhibitor in the previous 2 months and who had evaluable distal oesophageal biopsies were included (Diamond study: NCT00291746). Epithelial hyperplasia was identified when total epithelial thickness was at least 430 μm. Investigation-based GERD criteria were: presence of erosive oesophagitis, pathological oesophageal acid exposure and/or positive symptom-acid association probability. Symptoms were assessed using the Reflux Disease Questionnaire and a pre-specified checklist. Overall, 127 (55%) of the 231 included patients met investigation-based GERD criteria and 195 (84%) met symptom-based criteria. Epithelial hyperplasia was present in 89 individuals, of whom 61 (69%) met investigation-based criteria and 83 (93%) met symptom-based criteria. Adding epithelial hyperplasia as a criterion increased the number of patients diagnosed with GERD on investigation by 28 [12%; number needed to diagnose (NND): 8], to 155 (67%). The proportion of patients with a symptom-based GERD diagnosis who met investigation-based criteria including epithelial hyperplasia was significantly greater when concomitant epigastric pain was absent than when it was present (P < 0.05; NND: 8). Histology increases diagnosis of GERD and should be performed when clinical suspicion is high and endoscopy is negative. Excluding patients with epigastric pain enhances sensitivity for the diagnosis of GERD. © 2017 John Wiley & Sons Ltd.

2015-09-01

To provide a survey on the literature concerning the influence of respiratory physiotherapy on gastro-oesophageal reflux (GOR) in infants and young children. Electronic databases (Pubmed, Web of Science, PEDro) and reference lists of articles and narrative reviews were searched. Articles were included when infants and small children underwent oesophageal pH monitoring or pH-multichannel intraluminal impedance monitoring while respiratory physiotherapy was administered. Descriptive analysis was performed and two researchers scored the methodological quality of these studies. Out of 985 articles, seven (six English, one French) have been included, In total 277 patients were involved, 71 with cystic fibrosis. Depending on the technique used, four studies showed GOR to be aggravated during therapy, three studies reported no effect. The evidence is not conclusive on whether respiratory physiotherapy induces or aggravates GOR in infants and small children. Age, disease, and treatment options play an important role. More specific research, also focussing on the influence of respiratory physiotherapy on non-acid reflux and the impact of recently developed airway clearance techniques (ACT's) on GOR is necessary. © 2015 Wiley Periodicals, Inc.

Coeliac disease (CD) has been linked to gastro-oesophageal reflux disease (GORD). Previous studies have demonstrated an increased prevalence of reflux in patients with CD. However data on the risk for CD in patients presenting with reflux are conflicting. The aim of this study was to establish the prevalence of CD in patients with GORD and to elucidate the mechanisms for reflux symptoms in newly diagnosed CD patients. Group A: patients who had undergone routine duodenal biopsy were prospectively recruited between 2004 and 2014. Diagnostic yield was compared with that of a screening cohort. Group B: 32 patients with newly diagnosed CD who had undergone oesophageal manometry and 24-h pH studies were prospectively recruited. Group A: 3368 patients (58.7% female, mean age 53.4 years) underwent routine duodenal biopsy. Of these patients, 850 (25.2%) presented with GORD. The prevalence of CD among GORD patients was 1.3% (0.7-2.4%), which was not significantly higher than that in the general population (P=0.53). Within the context of routine duodenal biopsy at endoscopy (when corrected for concurrent symptoms, age and sex), reflux was found to be negatively associated with CD [adjusted odds ratio 0.12 (0.07-0.23), Preflux. On manometry, 9% had a hypotensive lower oesophageal sphincter and 40.6% had oesophageal motor abnormalities, with 25% significantly hypocontractile. On pH studies, 33% demonstrated reflux episodes. The prevalence of undiagnosed CD among GORD patients is similar to that in the general population, and routine duodenal biopsy cannot be recommended. A significant number of patients with newly diagnosed CD were found to have reflux and/or oesophageal dysmotility on pH/manometry studies; this may explain the high prevalence of reflux symptoms in CD.

Chest physiotherapy is regularly prescribed for children, particularly in cystic fibrosis. Gastro-oesophageal reflux is common in this disease and is associated with certain chest physiotherapy manoeuvres. To evaluate the influence of two chest physiotherapy techniques on gastro-oesophageal reflux in children. Twenty-nine children were investigated by routine pHmetry. During the examination, they performed two chest physiotherapy manoeuvres in a seated position for 10 minutes each with a 5 minutes rest between them. The two manoeuvres used were a slow expiration technique (ELPr) and positive expiratory pressure (PEP). It was a prospective study and the order of manoeuvres was randomised. The pH traces were analysed blindly when all the studies had been completed. In the sample, 21% of children had gastro-oesophageal reflux during the physiotherapy session. No relationship was found between reflux during physiotherapy and pathological reflux (P=0.411) nor the physiotherapy technique used (P=0.219). The use of these two chest physiotherapy techniques in children in a seated position can produce gastro-oesophageal reflux. Copyright © 2015 SPLF. Published by Elsevier Masson SAS.

To study the incidence and pattern of gastro-oesophageal reflux disease (GORD) in patients with mild-to-moderate chronic obstructive pulmonary disease (COPD) using dual-probe 24-h oesophageal pH recording. This was a prospective study of 50 patients with mild-to-moderate stage COPD based on the Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidelines. A detailed history of illness along with spirometry was done in all patients. In the study group, reflux symptoms were measured using a validated scoring system. All the patients underwent oesophageal manometry and dual-probe 24-h oesophageal pH recording. Symptoms of gastro-oesophageal reflux were present in 38 patients. Twenty-four-hour oesophageal pH monitoring revealed pathological reflux in 31 out of 38 symptomatic and 8 out of 12 asymptomatic patients. The overall rate of GORD was 78% in our study. Only distal GORD was observed in 11 (28.9%), and both distal and proximal GORD was observed in 20 (52.6%) out of the 38 symptomatic subjects. In the remaining 12 asymptomatic patients, eight had GORD. Distal GORD was present in six (50%) patients, and two (16.6%) had both distal and proximal GORD in this group. Isolated proximal GORD was not observed in any patient. There is an increased occurrence of GORD in patients with even mild-to-moderate COPD. © 2013 The Authors.

Gastro-oesophageal reflux disease (GORD) has been implicated in the development of chronic rhinosinusitis (CRS). The association of GORD with CRS is systematically assessed from the medical literature. Embase and MEDLINE were searched using a comprehensive strategy limited to English language and Human subjects. Any study with original data on the experimental, diagnostic, treatment or prognostic association of CRS with GORD was included. Studies without a control group, case reports and review articles were excluded. The search returned 958 records, with an additional 10 found from bibliographic lists; this produced 32 studies. The included studies (n=32) consisted of studies reporting pathogenic factors (n=20), epidemiological association (n=8), prognostic interactions (n=3), and a combination of these outcomes (n=1). Potential pathogenic roles for GORD in CRS were supported; CRS subjects had greater prevalence of intranasal Helicobacter pylori and acid reflux than subjects without CRS. CRS is more prevalent in GORD sufferers than those without GORD. Evidence is conflicting for GORD as a factor in CRS treatment failure. The results support a significant association of GORD with CRS. Physicians should be cognizant of the potential for acid and non-acid reflux as a driving factor in CRS.

There is potential for gastro-oesophageal reflux disease (GORD) to be under-diagnosed by physicians. A quick, focused examination, requiring no special equipment, of a patients' dentition can assist in making a more accurate diagnosis where GORD is suspected. Guidance is provided for physicians as to what intra-oral signs are suggestive of intrinsic dental erosion, which is a clinical feature of GORD and its associated conditions. Use of this information will, it is suggested, improve outcomes for patients where GORD is suspected. © 2016 Royal Australasian College of Physicians.

Continuous versus bolus intragastric tube feeding for preterm and low birth weight infants with gastro-oesophageal reflux disease.

Gastro-oesophageal reflux disease is a particularly common condition in preterm and low birth weight infants. These infants are also more likely to have excessive regurgitation, as they do not have a fully developed antireflux mechanism. Preterm and low birth weight infants who are unable to suck oral feeds are required to be fed via an intragastric tube for varying lengths of time. Intragastric tube feeding can be delivered by the intermittent bolus or continuous feeding method. Use of continuous or intermittent bolus intragastric feeding may have a positive or negative effect on the incidence or severity of gastro-oesophageal reflux disease. To determine whether continuous or intermittent bolus intragastric tube feeding reduces the number of episodes and the duration of gastro-oesophageal reflux disease (GORD) in preterm and low birth weight infants.We intended to perform subgroup analyses for gestational age; birth weight; age in days from birth at full enteral feeding via intragastric tube (breast vs bottle); frequency of intermittent bolus feed; and type of medication for treatment of GORD (only if medication prescribed and given similarly to both intervention groups). We used the standard search strategy of the Cochrane Neonatal Group as described in The Cochrane Library (www.thecochranelibrary.com) to search for randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (CENTRAL) (2013, Issue 9), MEDLINE (1966 to September 2013), EMBASE (1980 to September 2013) and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) (1982 to September 2013). We also searched previous reviews, including cross-references, abstracts and conference and symposia proceedings of the Perinatal Society of Australia and New Zealand and the Pediatric Academic Societies (American Pediatric Society/Society for Pediatric Research and European Society for Paediatric Research) from 1990 to 2012.

Gastro-oesophageal reflux (GOR) is a common disorder encountered during childhood. Early diagnosis and treatment is essential to prevent serious complications. There are several methods for the diagnosis of GOR, with variable opinions regarding which one is the most sensitive and specific. Objective. This is a retrospective study comparing 24-h oesophageal pH monitoring and barium examinations in the diagnosis of GOR in children. Patients and methods. All children referred with signs and/or symptoms of GOR from January to December 1996 at Great Ormond Street Hospital, London, UK, were included in the study. The recorded results (presence or absence of reflux) of barium examinations and 24-h oesophageal pH monitoring studies performed on 169 children were retrospectively reviewed and compared. Results. One-third of patients were below 1 year of age. In all age groups, oesophageal pH probe studies showed a high detection rate (83%) and low incidence of false-negative results (7%) compared to barium examinations, which showed a lower detection rate (43%) and higher incidence of false-negative results (48%). Most GOR-related anatomical abnormalities diagnosed by barium examinations were identified in infants below 1 year of age. Conclusions. We believe that 24-h oesophageal pH monitoring should be used as the first line of investigation for the diagnosis of GOR in all children regardless of the age group. Barium examinations can be reserved for patients below 1 year of age, those going for surgery and those with negative oesophageal pH monitoring results but strong clinical suspicion of GOR. (orig.)

The pathophysiology of chronic rhinosinusitis (CRS) is unclear. It has been discussed for decades whether gastro-oesophageal reflux (GOR) may be a contributing factor for some patients. The aim of the present study was to evaluate the level of GOR in an unselected group of patients with CRS using multichannel impedance-pH monitoring. Consecutive patients with CRS diagnosed using the EPOS2012 criteria, completed questionnaires on GOR symptoms and were offered 24-h multichannel intraluminal impedance (MII)-pH monitoring. The results were compared with a group of healthy controls. Forty-six patients completed MII-pH-monitoring and were compared with 45 control subjects, with comparable age and gender distributions. The median number of reflux episodes in the patients was 56.5 compared with 33 in controls, while, the numbers of proximal reflux episodes was 27.5 versus 3, respectively. Thirty nine patients had abnormal pH-impedance recordings compared with five controls. The CRS patients had significantly higher incidences of gastro-oesophageal reflux compared with asymptomatic controls. The results of this study suggest that GOR may be a causative or contributing factor of CRS.

There is still a debate about the exact measurement of the oesophagogastric junction and the diaphragmatic hiatus among clinicians. The aim of this study was to investigate the differences between landmark readings of gastroscopy on intubation and extubation, and to correlate these readings with a gastro-oesophageal reflux questionnaire. 116 cases who underwent diagnostic gastroscopy between January 2013 and June 2013 were included in this study. Landmark measurements were noted while withdrawing the endoscope and were also evaluated after the gastric air was fully emptied. We first used a frequency scale for the gastro-oesophageal reflux disease symptoms (FSSG) questionnaire in order to investigate dysmotility and acid reflux symptoms in the study population and correlated the FSSG questionnaire with intubation and extubation measurements at endoscopic examination. Mean age of included subjects was 49.41±17.7 (19-82) years. Males and females were equally represented. On FSSG scores, the total dysmotility score was 7.99±5.06 and the total score was 15.18±10.11. The difference between intubation and extubation measurements ranged from -3cm to +2cm (mean: -0.4). When an FSSG score of 30 was accepted as a cut-off value, we detected a significant difference between the measurements (p<0.05; t: 0.048). Accuracy of landmark measurements during gastroscopy is clearly affected from insertion or withdrawal of the endoscope. When differences in measurements between insertion and withdrawal were evident, comparable with the FSSG scores, the results became significantly different. In conclusion, according to FSSG scores, these measurements should be performed at the end of the endoscopy. Copyright © 2016 Pan-Arab Association of Gastroenterology. Published by Elsevier B.V.

The incidence of gastro-oesophageal reflux disease and Barrett's oesophagus is increasing. Barrett's oesophagus is the main precursor to oesophageal adenocarcinoma, which has a poor prognosis. In view of the vast potential burden of these diseases on patients and health-care resources, there is a real need to define and focus research efforts. This priority setting exercise aimed to produce a list of the top ten uncertainties in the field that reflect the priorities of patients and health-care providers. We adopted the robust and transparent methodologies previously outlined by the James Lind Alliance. This qualitative approach firstly involves an ideas gathering survey that, once distilled, generates a longlist of research uncertainties. These uncertainties are then prioritised via an interim ranking survey and a final workshop to achieve consensus agreement. The initial 629 uncertainties, generated from a survey of 170 individual respondents (47% professional, 53% non-professional) and one workshop, were narrowed down to the final top ten uncertainties of priority for future research. These priorities covered a range of issues, including a need for improved patient risk stratification, alternative diagnostic and surveillance tests, efficacy of a dedicated service for Barrett's oesophagus, cost-effectiveness and appropriateness of current surveillance, advances in development of non-drug treatments for gastro-oesophageal reflux disease, safety of long-term drug treatment, and questions regarding the durability and role of different endoscopic therapies for dysplastic Barrett's oesophagus. This is the first patient-centred assessment of priorities for researchers in this chronic disease setting. We hope that recognition and dissemination of these results will shape the future direction of research and translate into meaningful gains for patients. Copyright © 2017 Elsevier Ltd.

Determinants of oesophageal 'alkaline' pH environment in controls and patients with gastro-oesophageal reflux disease.

OpenAIRE

Singh, S; Bradley, L A; Richter, J E

1993-01-01

The determinants of the oesophageal alkaline pH environment are poorly understood. Saliva (pH 6.4-7.8) may be a major contributor, although some argue the importance of refluxed alkaline duodenal contents. Acid and alkaline reflux parameters were studied over 2 days in 30 subjects (control, oesophagitis and Barrett's patients; 10 each) using glass pH electrodes. In phase 1, one pH electrode was placed 1 cm below the upper oesophageal sphincter to assess the influence of saliva and the other 5...

We present demographic differences across the gastro-oesophageal reflux disease (GORD) spectrum in a UK District General Hospital. Data were prospectively collected over 37 years. At endoscopy patients were categorized as: erosive oesophagitis (EO), Barrett's oesophagus (BO) or nonerosive reflux disease (NER). Analysis 1: comparison of EO, BO and NER 1977-2001 when the database for GORD without BO closed. Analysis 2: demographic differences in oesophageal adenocarcinoma (OAC) in total BO population diagnosed 1977-2011. GORD 1977-2001 (n=11 944): sex, male predominance in EO and BO but not NER; male : female ratios, 1.81, 1.65, 0.87, respectively (P<0.0001); mean age at presentation, EO 54 years, BO 62 years, NER 50 years; women were older than men by 10, 7 and 6 years, respectively.BO 1977-2011: prevalent OAC, 87/1468 (6%); male : female ratio, 4.1 (P<0.0001); incident OAC, 54/1381 (3.9%); male : female ratio, 3.5 (P<0.0001). Among all BO, more men developed OAC (3 vs. 0.9%). Within each sex, proportion of OAC higher among men (4.9 vs. 2.3%); at OAC diagnosis women were slightly but not significantly older (69.9 vs. 72.3 years, P=0.322). Two views may explain our findings. First, women have either milder reflux, or reduced mucosal sensitivity hence reflux remains silent for longer. Alternatively, women genuinely develop reflux later, that is, are more protected and for longer from developing GORD and its complications. Early evidence is emerging that female sex hormones may indeed have a protective role in GORD during the reproductive period. We suggest reflux and its consequences may be an example of 'protection' conferred on Eve.

Radiologic diagnosis of gastro-oesophageal reflux by means of graded abdominal compression

Energy Technology Data Exchange (ETDEWEB)

Fransson, S.G.; Soekjer, H.; Johansson, K.E.; Tibbling, L.

The aim of the study was to ascertain whether abdominal compression by a standardized technique increases the reliability of the radiologic diagnosis of gastro-oesophageal reflux. Eighty-eight patients were examined by means of a manometric reflux test, 24-hour measurements of pH and endoscopy. The radiologic examination was performed with and without graded abdominal compression, the patient at the same time turning from side to side. When abdominal compression was included the result of the radiologic examination was positive in 31 patients. In the absence of abdominal compression reflux was detected in 11 of these patients. In one patient reflux was detected only without compression. All these 31 patients had one more test positive and in 27 at least 2 more tests were positive. Another 21 patients had reflux disease as indicated by at least 2 of the 3 other tests. The compression technique seems to yield no false positive responses, and proved to be significantly more reliable than examinations without compression.

Limited data exist on the impact of regurgitation on health-related quality of life (HRQOL) in gastro-oesophageal reflux disease (GORD). We assessed the relationship between regurgitation frequency and HRQOL before and after acid suppression therapy in GORD. We used data from two randomised trials of AZD0865 25-75 mg/day versus esomeprazole 20 or 40 mg/day in non-erosive reflux disease (NERD) (n=1415) or reflux oesophagitis (RO) (n=1460). The Reflux Disease Questionnaire was used to select patients with frequent and intense heartburn for inclusion and to assess treatment response. The Quality of Life in Reflux and Dyspepsia (QOLRAD) questionnaire was used to assess HRQOL. At baseline, 93% of patients in both the NERD and RO groups experienced regurgitation. Mean QOLRAD scores were similar for NERD and RO at baseline and at week 4 and disclosed decremental HRQOL with increasing frequency of regurgitation; a clinically relevant difference of >0.5 in mean QOLRAD scores was seen with regurgitation ≥4 days/week versus <4 days/week. The prevalence of frequent, persistent regurgitation (≥4 days/week) at week 4 among heartburn responders (≤1 day/week of mild heartburn) was 28% in NERD and 23% in RO. QOLRAD scores were higher among heartburn responders. There was a similar pattern of impact related to regurgitation frequency in heartburn responders compared with the group as a whole. Frequent regurgitation was associated with a clinically relevant, incremental decline in HRQOL beyond that associated with heartburn before and after potent acid suppression in both NERD and RO.

The mechanisms underlying symptoms in non-erosive reflux disease (NERD) remain to be elucidated. Non-erosive reflux disease patients appear to be more sensitive to intraluminal stimula than erosive patients, the proximal oesophagus being the most sensitive. In order to assess regional oesophageal changes in reflux acidity and sensitivity to reflux, according either to the acidity or the composition of the refluxate, combined multiple pH and multiple pH-impedance (pH-MII) was performed in 16 NERD patients. According to multiple pH-metry, 29% and 12% of reflux events reached the middle and proximal oesophagus respectively, and 35% and 19% according to conventional pH-MII (P acid reflux became weakly acidic at the proximal oesophagus. In all patients, the frequency of symptomatic refluxes, both acid and weakly acidic, was significantly higher at the proximal, compared with distal oesophagus (25 +/- 8%vs 11 +/- 2% for acid reflux and 27 +/- 8%vs 8 +/- 2% for weakly acidic reflux; P reflux. As approximately 30% of acid reflux becomes weakly acidic along the oesophageal body, to better characterize proximal reflux, in clinical practice, combined proximal pH-impedance monitoring should be used. In NERD patients, the proximal oesophagus seems to be more sensitive to both acid and weakly acidic reflux.

Gastro-oesophageal reflux disease (GERD) is incriminated as a cause of non-asthmatic infantile wheeze. To date, no diagnostic test is considered standard for GERD-related airway reflux diagnosis. Oesophageal combined multiple channel intraluminal impedance and pH (MII-pH) monitoring is proposed to be a sensitive tool for evaluation of all GERD including infantile wheeze. We aimed to determine the GERD prevalence amongst wheezy infants in the first year of life using combined MII-pH versus pH monitoring alone and evaluate the sensitivity and specificity of objective MII-pH monitoring parameters in GERD-associated infantile wheeze diagnosis compared to those of lipid-laden macrophage index (LLMI). Thirty-eight wheezy infants below 1year of age were evaluated for GERD using oesophageal combined MII-pH monitoring and LLMI. Totally, 60.5% of cases had abnormal MII-pH; only 7.9% of them had abnormal pH monitoring. LLMI was significantly higher in wheezy infants with abnormal MII-pH than infants with normal MII-pH monitoring (112±88 versus 70±48; P=0.036). The current definitions of abnormal MII-pH study, reflux index≥10% and distal reflux episodes≥100, had low sensitivity (23%) but high specificity (100% and 96%, respectively) in GERD-related aspiration diagnosis defined by LLMI≥100. Using ROC curves, bolus contact time≥2.4% and proximal reflux episodes≥46 had 61% and 54% sensitivity and 64% and 76% specificity, respectively, in GERD-related aspiration diagnosis. Combined MII-pH is superior to pH monitoring in reflux-associated infantile wheeze diagnosis. Objective data including proximal reflux episodes and bolus contact time should be combined with the current parameters used in reflux-associated infantile wheeze diagnosis.

Proton pump inhibitors and laparoscopic anti-reflux surgery (LARS) offer long-term symptom control to patients with gastro-oesophageal reflux disease (GERD). To evaluate the process of 'normalisation' of the squamous epithelium morphology of the distal oesophagus on these therapies. In the LOTUS trial, 554 patients with chronic GERD were randomised to receive either esomeprazole (20-40 mg daily) or LARS. After 5 years, 372 patients remained in the study (esomeprazole, 192; LARS, 180). Biopsies were taken at the Z-line and 2 cm above, at baseline, 1, 3 and 5 years. A severity score was calculated based on: papillae elongation, basal cell hyperplasia, intercellular space dilatations and eosinophilic infiltration. The epithelial proliferative activity was assessed by Ki-67 immunohistochemistry. A gradual improvement in all variables over 5 years was noted in both groups, at both the Z-line and 2 cm above. The severity score decreased from baseline at each subsequent time point in both groups (P refluxate seems to play the predominant role in restoring tissue morphology. © 2017 John Wiley & Sons Ltd.

Background: Caustic injury of the oesophagus not only causes luminal narrowing but is also responsible for longitudinal contraction, resulting in gastro-oesophageal reflux (GOR), which leads to failure of conventional therapy. Therefore, the development of GOR should be investigated periodically to direct appropriate management of these patients. Purpose: To determine the ability of scintigraphy to detect GOR in children with caustic oesophageal strictures in comparison with barium study and 24-h pH monitoring. Materials and methods: Seventeen children with caustic oesophageal injury underwent scintigraphy, an upper GI barium study and 24-h pH monitoring within the same week. Five patients were also investigated post-operatively for the assessment of surgical outcome after antireflux surgery. Results: On the whole, there was good correlation (r = 0.78, P < 0.00 l) between scintigraphy and 24-h oesophageal pH monitoring. Scintigraphy detected all but one (9/10) refluxing patients and also correctly identified all (7/7) non-refluxing patients. Barium studies demonstrated 6 out of 10 refluxing patients. There were no false-positive barium studies in non-refluxing patients. Post-operative studies demonstrated no evidence of GOR in surgically treated patients. Conclusions: Our results indicate that, by comparison with barium studies, scintigraphy is useful in the detection of GOR in cases with caustic oesophageal strictures and may be used as a screening modality for those under clinical follow-up.

Gastro-oesophageal reflux symptoms (GERS) are common in the community. However, few studies have examined their long-term natural history, or impact on survival. To examine these issues in individuals recruited into a community-based screening programme for Helicobacter pylori in 1994. Data on mortality and cause of death at 10 years were obtained from the Office for National Statistics. Baseline demographic data, lifestyle factors, gastrointestinal symptoms and quality of life were recorded at study entry. The effect of all these factors on persistent and new-onset GERS, and 10-year mortality, were examined using univariate and multivariate analysis, with results expressed as odds ratios (ORs) or hazard ratios (HR) with 99% confidence intervals (CI). Of 3967 individuals providing complete GERS data at baseline and 10 years, 549 (13.8%) had GERS at baseline. Of these, 183 (33.3%) had persistent symptoms. Among 3418 individuals asymptomatic at baseline, approximately 0.8% per year developed new-onset GERS. No predictors of persistent GERS were identified. New-onset symptoms were associated with lower quality of life or presence of irritable bowel syndrome (IBS) at baseline, and higher body mass index (BMI) at 10 years. There were 8331 (99.1%) of 8407 subjects providing complete GERS data at baseline, 1289 (15.5%) of whom were symptomatic. Presence of GERS at baseline did not affect survival (HR: 0.84; 99% CI: 0.44-1.59). Gastro-oesophageal reflux symptoms persisted in one-third of individuals, whilst new-onset gastro-oesophageal reflux symptoms were associated with poor quality of life, irritable bowel syndrome and higher body mass index. Gastro-oesophageal reflux symptoms did not impact adversely on survival. © 2012 Blackwell Publishing Ltd.

Scintigraphic demonstration of bile reflux after gastro-intestinal surgery

Energy Technology Data Exchange (ETDEWEB)

Bile reflux may occur after a variety of reconstructive procedures in the gastro-intestinal tract and biliary system. The present paper deals with reflux into the duodenum, jejunum, stomach, oesophagus and into blind loops. The demonstration of reflux by sup(99m)Tc labelled IDA acid derivatives, and a possible quantitative approach, are discussed. The advantages of isotope methods are: 1. Direct demonstration of bile reflux without any intervention in the physiological process and with little trouble to the patient. 2. The ability to use the method for various reconstructive procedures and 3. the additional information obtained which may help in the differential diagnosis of blind loops, biliary obstruction, cholecystitis or liver metastases if there has been a gastrectomy for a malignant tumour. In combination with a second administration of a radio-isotope tracer, one may be able to demonstrate abnormalities in the motility of the stomach or gut, or pyloric stenosis or gastro-oesophageal reflux.

Water syphon test and gastrooesophageal reflux during childhood (correlation with the clinical findings and oesophageal manometry)

Energy Technology Data Exchange (ETDEWEB)

Fotter, R.; Hoellwarth, M.

1981-07-01

The water syphon test is a simple and easily performed method for demonstrating gastro-oesophageal reflux with a high degree of reliability. It is carried out following a conventional barium swallow. Compared with clinical findings and oesophageal manometry, the water syphon test is very reliable for demonstrating gastro-oesophageal reflux during childhood. Prolonged irradiation in order to see spontaneous reflux becomes unnecessary. This results in a significant reduction in radiation dose. Barium swallow and the water syphon test are the most useful initial examinations in children with symptoms which suggest reflux.

Analytical sensitivity of Tc99m radionuclide 'milk' scanning in the detection of gastro-oesophageal reflux

Energy Technology Data Exchange (ETDEWEB)

Paton, J.Y.; Nanayakkara, C.S.; Cosgriff, P.S.

1985-09-01

The analytical sensitivity of radionuclide ''milk'' scans for detecting gastro-oesophageal reflux (GOR) has been assessed using an in vitro simulation test. Five factors were found to affect the ability to detect simulated reflux: isotope concentration, absolute gamma camera sensitivity, absorber thickness overlying the ''oesophagus'' and volume and duration of reflux. We found that a critical volume-duration product must be exceeded for reflux to be detected. Radionuclide milk scanning appears to be much less sensitive in detecting transient events like GOR than might be expected from previously reported static simulation studies.

A study of the effect of nasal modes of ventilation on the incidence of gastro-oesophageal reflux in preterm neonates.

Nasal modes of respiratory support cause variable amounts of gastric dilatation which may increase gastro-oesophageal reflux (GER) in preterms. To compare the incidence of GER in nasally ventilated, preterm babies with controls (babies not on ventilation). A prospective, observational comparative study. Twenty-three preterm babies of gestational age 28-36 weeks and weight ranging between 1,000 g and Reflux index (RI) was calculated as the percentage of study time the lower oesophageal pH was reflux with symptoms if any. Numerical data were shown as mean with standard deviation and statistical comparisons were done using the χ(2)-test, Fischer test, and t-test wherever applicable. The RI was higher in ventilated babies as compared to the control group, particularly in the subgroup A, where test babies formed their own controls. Grade IV reflux (7 cases) was seen only in the ventilated babies. There was no difference in the incidence of GER in babies on nCPAP as compared with nIPPV. Grade IV reflux could not be reliably predicted by RI alone. No definite temporal relation between episodes of reflux and symptoms could be determined in this study. There is an increase in GER in preterms on nasal modes of ventilation. A combination of upper (pharyngeal) and lower oesophageal sensors are preferred to a single lower oesophageal sensor when assessing GER by oesophageal pHmetry in neonates.

The aim of this study was to investigate whether an increased frequency of gastro-oesophageal reflux (GOR) is more common in large-sized, deep-chested dogs undergoing spinal surgery in sternal recumbency than in small-sized, barrelchested dogs. Prospective, cohort study. Nineteen small-sized, barrel-chested dogs (group B) and 26 large-sized, deep-chested dogs (group D). All animals were premedicated with intramuscular (IM) acepromazine (0.05 mg kg -1 ) and pethidine (3 mg kg -1 ) IM. Anaesthesia was induced with intravenous sodium thiopental and maintained with halothane in oxygen. Lower oesophageal pH was monitored continuously after induction of anaesthesia. Gastro-oesophageal reflux was considered to have occurred whenever pH values > 7.5 or < 4 were recorded. If GOR was detected during anaesthesia, measures were taken to avoid aspiration of gastric contents into the lungs and to prevent the development of oesophagitis/oesophageal stricture. The frequency of GOR during anaesthesia was significantly higher in group D (6/26 dogs; 23.07%) than in group B (0/19 dogs; 0%) (p = 0.032). Signs indicative of aspiration pneumonia, oesophagitis or oesophageal stricture were not reported in any of the GOR cases. In large-sized, deep-chested dogs undergoing spinal surgery in sternal recumbency, it would seem prudent to consider measures aimed at preventing GOR and its potentially devastating consequences (oesophagitis/oesophageal stricture, aspiration pneumonia).

To investigate the relationship between use of asthma medication and nitrates and risk of reflux oesophagitis, Barrett's oesophagus and oesophageal adenocarcinoma. Data were collected on use of asthma medication and nitrates at least 1 year before interview from patients with reflux oesophagitis, Barrett's oesophagus and oesophageal adenocarcinoma. Associations between use of asthma medications and nitrates and the risk of reflux oesophagitis, Barrett's oesophagus and oesophageal adenocarcinoma were estimated using multiple logistic regression. Nine hundred and forty-one subjects were recruited: 230 reflux oesophagitis, 224 Barrett's oesophagus, 227 oesophageal adenocarcinoma patients and 260 population controls. Barrett's oesophagus patients were more likely than controls to have had a diagnosis of asthma (odds ratio 2.15, 95% confidence interval 1.15-4.03) and to have used asthma medications (odds ratio 2.13, 95% confidence interval 1.09-4.16). No significant associations were observed between use of asthma medication or nitrates and reflux oesophagitis or oesophageal adenocarcinoma. Gastro-oesophageal reflux symptoms appear to confound the association between asthma medication use and Barrett's oesophagus. However, it is possible that asthma medications may increase the risk of Barrett's oesophagus by other mechanisms.

Non-nutritive sucking for gastro-oesophageal reflux disease in preterm and low birth weight infants.

Gastro-oesophageal reflux (GOR) is commonly diagnosed in the neonatal population (DiPietro 1994), and generally causes few or no symptoms (Vandenplas 2009). Conversely, gastro-oesophageal reflux disease (GORD) refers to GOR that causes troublesome symptoms with or without complications such as damage to the oesophagus (Vandenplas 2009). Currently there is no evidence to support the range of measures recommended to help alleviate acid reflux experienced by infants. Non-nutritive sucking (NNS) has been used as an intervention to modulate neonatal state behaviours through its pacifying effects such as decrease infant fussiness and crying during feeds (Boiron 2007; Pickler 2004). To determine if NNS reduces GORD in preterm infants (less than 37 weeks' gestation) and low birth weight (less than 2500 g) infants, three months of age and less, with signs or symptoms suggestive of GORD, or infants with a diagnosis of GORD. We performed computerised searches of the electronic databases of the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 9, 2013), MEDLINE (1966 to September 2013), CINAHL (1982 to September 2013), and EMBASE (1988 to September 2013). We applied no language restrictions. Controlled trials using random or quasi-random allocation of preterm infants (less than 37 weeks' gestation) and low birth weight (less than 2500 g) infants three months of age and less with signs or symptoms suggestive of GORD, or infants with a diagnosis of GORD. We included studies reported only by abstracts, and cluster and cross-over randomised trials. Two review authors independently reviewed and selected trials from searches, assessed and rated study quality and extracted relevant data. We identified two studies from the initial search. After further review, we excluded both studies. We identified no studies examining the effects of NNS for GORD in preterm and low birth weight infants There was insufficient evidence to determine the effectiveness of NNS for GORD

Full Text Available Abstract Background Gastro-oesophageal reflux disease (GORD symptoms are common in asthma and have been extensively studied, but less so in the Asian continent. Reflux-associated respiratory symptoms (RARS have, in contrast, been little-studied globally. We report the prevalence of GORD symptoms and RARS in adult asthmatics, and their association with asthma severity and medication use. Methods A cross-sectional analytical study. A validated interviewer-administered GORD scale was used to assess frequency and severity of seven GORD symptoms. Subjects were consecutive asthmatics attending medical clinics. Controls were matched subjects without respiratory symptoms. Results The mean (SD composite GORD symptom score of asthmatics was significantly higher than controls (21.8 (17.2 versus 12.0 (7.6; P P Conclusions GORD symptoms and RARS were more prevalent in a cohort of Sri Lankan adult asthmatics compared to non-asthmatics. Increased prevalence of RARS is associated with both typical and atypical symptoms of GORD. Asthma disease and its severity, but not asthma medication, appear to influence presence of GORD symptoms.

Partial fundoplications provide similar reflux control with fewer post-fundoplication symptoms compared with Nissen fundoplication for gastro-oesophageal reflux disease (GORD). The best choice of procedure for partial fundoplication remains unclear. The aim of this study was to compare the outcome of two different types of partial fundoplication for GORD. A double-blind RCT was conducted between 2012 and 2015 in two hospitals specializing in antireflux surgery. Patients were randomized to undergo either a laparoscopic 270° posterior fundoplication (Toupet) or a laparoscopic 180° anterior fundoplication. The primary outcome was postoperative dysphagia at 12 months, measured by the Dakkak score. Subjective outcome was analysed at 1, 3, 6 and 12 months after surgery. Objective reflux control was assessed before and 6 months after surgery. Ninety-four patients were randomized to laparoscopic Toupet or laparoscopic 180° anterior fundoplication (47 in each group). At 12 months, 85 patients (90 per cent) were available for follow-up. Objective scores were available for 76 (81 per cent). Postoperative Dakkak dysphagia score at 12 months was similar in the two groups (mean 5·9 for Toupet versus 6·4 for anterior fundoplication; P = 0·773). Subjective outcome at 12 months demonstrated no significant differences in control of reflux or post-fundoplication symptoms. Overall satisfaction and willingness to undergo surgery did not differ between the groups. Postoperative endoscopy and 24-h pH monitoring showed no significant differences in mean oesophageal acid exposure time or recurrent pathological oesophageal acid exposure. Both types of partial fundoplication provided similar control of GORD at 12 months, with no difference in post-fundoplication symptoms.

This study aimed to resolve controversy regarding the effects of Helicobacter pylori eradication therapy and H. pylori infection in gastro-oesophageal reflux disease. A randomized, double-blind, multicentre trial was performed in patients presenting with reflux symptoms. H. pylori-positive patients were randomized to receive either antibiotics or placebo for 7 days. H. pylori-negative patient controls received placebo. All received esomeprazole 20 mg b.d. for 7 days, followed by 40 mg o.d. to complete an 8-week course, and were followed up for 32 weeks by telephone. In this study, 198/589 (34%) patients were H. pylori-positive and 113 H. pylori-negative patients served as controls. Baseline endoscopy revealed 63% Los Angeles grade 0A and 37% Los Angeles grade BCD oesophagitis with no difference between patient groups. Symptom improvement on esomeprazole was seen in 89%. H. pylori eradication was successful in 82%. H. pylori eradication had no effect on symptomatic relapse (hazard ratio 1.15, 95% CI 0.74-1.8; p = 0.5). Overall, H. pylori-positive patients had a lower probability of relapse compared to H. pylori-negative controls (hazard ratio 0.6, 95% CI 0.43-0.85; p = 0.004). Relapse hazard was modulated also by oesophagitis grade (BCD vs. 0A, hazard ratio 2.1, 95% CI 1.5-3.0). Relapse of gastro-oesophageal reflux disease symptoms after a course of high dose acid suppression took longer for H. pylori-positive patients than H. pylori-negative controls; however eradication therapy had no effect on the risk of relapse; ClincialTrials.gov number, NCT00574925.

The aims of this observational study were (i) to examine the prevalence of symptomatic and clinically silent proximal and distal gastro-oesophageal reflux (GOR) in adults with chronic obstructive pulmonary disease (COPD) or bronchiectasis, (ii) the presence of gastric aspiration, and (iii) to explore the possible clinical significance of this comorbidity in these conditions. Twenty-seven participants with COPD, 27 with bronchiectasis and 17 control subjects completed reflux symptom evaluation and dual-channel 24 h oesophageal pH monitoring. In those with lung disease, pepsin levels in sputum samples were measured using enzyme-linked immunosorbent assay, with disease severity (lung function and high-resolution computed tomography) also measured. The prevalence of GOR in COPD was 37%, in bronchiectasis was 40% and in control subjects was 18% (P = 0.005). Of those diagnosed with GOR, clinically silent reflux was detected in 20% of participants with COPD and 42% with bronchiectasis. While pepsin was found in 33% of COPD and 26% of bronchiectasis participants, the presence of pepsin in sputum was not related to a diagnosis of GOR based on oesophageal pH monitoring in either condition. Neither a diagnosis of GOR nor the presence of pepsin was associated with increased severity of lung disease in COPD or bronchiectasis. The prevalence of GOR in COPD or bronchiectasis is twice that of the control population, and the diagnosis could not be based on symptoms alone. Pepsin was detected in sputum in COPD and bronchiectasis, suggesting a possible role of pulmonary aspiration, which requires further exploration. © 2013 The Authors.

Gastro-oesophageal reflux (GOR) is a common disorder, characterised by regurgitation of gastric contents into the oesophagus. GOR is a very common presentation in infancy in both primary and secondary care settings. GOR can affect approximately 50% of infants younger than three months old (Nelson 1997). The natural history of GOR in infancy is generally that of a functional, self-limiting condition that improves with age; gastro-oesophageal reflux disease (GORD) and its precise distinction from GOR are debated, but consensus guidelines from the North American Society of Gastroenterology, Hepatology and Nutrition (NASPGHAN-ESPGHAN guidelines 2009) define GORD as 'troublesome symptoms or complications of GOR.' This Cochrane review aims to provide a robust analysis of currently available pharmacological interventions used to treat children with GOR by assessing all outcomes indicating benefit or harm. We sought to identify relevant published trials by searching the Cochrane Central Register of Controlled Trials (CENTRAL) (2014, Issue 5), MEDLINE and EMBASE (1966 to 2014), the Centralised Information Service for Complementary Medicine (CISCOM), the Institute for Scientific Information (ISI) Science Citation Index (on BIDS-UK General Science Index) and the ISI Web of Science. We also searched for ongoing trials in the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com).Reference lists from trials selected by electronic searching were handsearched for relevant paediatric studies on medical treatment of children with gastro-oesophageal reflux, as were published abstracts from conference proceedings (published in Gut and Gastroenterology) and reviews published over the past five years.No language restrictions were applied. Abstracts were reviewed by two review authors, and relevant RCTs on study participants (birth to 16 years) with GOR receiving a pharmacological treatment were selected. Subgroup analysis was considered for children up to 12 months of age

The purpose of this study was to assess the prevalence of tooth wear, symptoms of reflux and salivary parameters in a group of patients referred for investigation of gastro-oesophageal reflux disease (GORD) compared with a group of control subjects. Tooth wear, stimulated salivary flow rate and buffering capacity and symptoms of GORD were assessed in patients attending an Oesophageal Laboratory. Patients had manometry and 24-h pH tests, which are the gold standard for the diagnosis of GORD. Tooth wear was assessed using a modification of the Smith and Knight tooth wear index. The results were compared to those obtained from a group of controls with no symptoms of GORD. Patients with symptoms of GORD and those subsequently diagnosed with GORD had higher total and palatal tooth wear (p<0.05). The buffering capacity of the stimulated saliva from the control subjects was greater than patients with symptoms of GORD (p<0.001). Patients with hoarseness had a lower salivary flow rate compared with those with no hoarseness. Tooth wear involving dentine was more prevalent in patients complaining of symptoms of GORD and those diagnosed as having GORD following 24-h pH monitoring than controls. Patients had poorer salivary buffering capacity than control subjects. Patients complaining of hoarseness had lower salivary flow rate than controls.

Gastro-oesophageal reflux (GOR) is common in patients with cystic fibrosis (CF). The aim of this study was to investigate the relationship between gastric emptying (GE) and GOR in children with CF. Multichannel intraluminal impedance-pH monitoring (MII-pH) to measure GOR and GE breath test (GEBT) to measure GE were performed in 28 children with symptoms suggestive for GOR disease (GORD) (group 1). GEBT was performed in another 28 children with/without GOR symptoms who agreed to undergo GEBT but not MII-pH (group 2). In group 1, we found increased acid GOR (AGOR) in 46.4% and delayed GE (DGE) in 21.4% but no relationship between increased AGOR and DGE. There was no DGE in group 2. We found DGE in 10.7% and rapid GE in 12.5% of the whole group. Almost half of the children with CF and symptoms suggestive for GORD have increased AGOR and almost a quarter has DGE. However, there was no relation between GOR and GE. Copyright © 2015 European Cystic Fibrosis Society. Published by Elsevier B.V. All rights reserved.

The aim of this study was to evaluate the attitudes and practices of Australian general practitioners (GPs) regarding infant gastro-oesophageal reflux disease (GORD) diagnosis and management. A national cross-sectional survey, involving a random sample of currently practising Australian GPs (n = 2319) was undertaken between July and September 2011. GPs attitudes and management of infant GORD were surveyed via an online and paper-based 41-item questionnaire. In total, 400 responses were analysed (17.24% response rate). The majority of GPs employed empirical trials of acid-suppression medication and/or lifestyle modifications to diagnose infant GORD. GPs frequently recommended dietary modification despite the belief that they were only moderately effective at best. In addition, GPs frequently prescribed acid-suppression medication, despite concerns regarding their safety in the infant population. Other GP concerns included the lack of clinical guidelines and education for GPs about infant GORD, as well as the level of evidence available for the safety and efficacy of diagnostic tests and treatments. Despite the important role Australian GPs play in the diagnosis and management of infant GORD, high-level evidence-based guidelines for GPs are lacking. Consequently, GPs engage in diagnostic and management practices despite their concerns regarding the safety and effectiveness. © 2015 The Authors.

The objective of this study was to evaluate the validity of the Heartburn Reflux Dyspepsia Questionnaire (HRDQ), a newly developed measure of gastro-oesophageal reflux disease (GORD) symptoms. Specifically, the HRDQ was developed for patients, who still experience symptoms with proton pump inhibitor (PPI) treatment. The psychometric properties of HRDQ were evaluated based on data from two clinical trials of patients with GORD with a partial response to PPIs, one from the UK and one from Denmark and Germany. The HRDQ had good internal consistency (Cronbach's alpha range .83-.88) and test-retest reliability (intraclass correlation coefficient range .71-.90). Convergent and discriminant validity were supported by high correlations with ReQuest™ and ability to differentiate between groups based on ReQuest™ cut-off values. Responsiveness of HRDQ was demonstrated by moderate to high correlations with ReQuest™ change scores and time with symptoms. An HRDQ cut-off value of 0.70 for definition of 'bad day' was also evaluated. Based on existing evidence, the HRDQ is a valid and reliable measure of GORD symptoms that can be used as a study outcome in clinical trials.

Lesogaberan (AZD3355) is a novel γ-aminobutyric acid B-type receptor agonist designed to treat gastro-oesophageal reflux disease (GERD) by inhibiting transient lower oesophageal sphincter relaxations. A randomised, double-blind, placebo-controlled, multi-centre phase IIb study was performed to assess the efficacy and safety of lesogaberan as an add-on to proton pump inhibitor (PPI) therapy in patients with GERD who are partially responsive to PPI therapy (ClinicalTrials.gov reference: NCT01005251). In total, 661 patients were randomised to receive 4 weeks of placebo or 60, 120, 180 or 240 mg of lesogaberan twice daily, in addition to ongoing PPI therapy. Symptoms were measured using the Reflux Symptom Questionnaire electronic Diary. Response to treatment was defined as having an average of ≥ 3 additional days per week of not more than mild GERD symptoms during treatment compared with baseline. In the primary analysis, 20.9%, 25.6%, 23.5% and 26.2% of patients responded to the 60, 120, 180 and 240 mg twice daily lesogaberan doses, respectively, and 17.9% responded to placebo. The response to the 240 mg twice daily dose was statistically significantly greater than the response to placebo using a one-sided test at the predefined significance level of p < 0.1. However, the absolute increases in the proportions of patients who responded to lesogaberan compared with placebo were low. Lesogaberan was generally well tolerated, although six patients receiving lesogaberan developed reversible elevated alanine transaminase levels. In patients with GERD symptoms partially responsive to PPI therapy, lesogaberan was only marginally superior to placebo in achieving an improvement in symptoms.

Gastro-oesophageal reflux (GOR) is common in infants, and feed thickeners are often used to manage it in infants as they are simple to use and perceived to be harmless. However, conflicting evidence exists to support the use of feed thickeners. To evaluate the use of feed thickeners in infants up to six months of age with GOR in terms of reduction in a) signs and symptoms of GOR, b) reflux episodes on pH probe monitoring or intraluminal impedance or a combination of both, or c) histological evidence of oesophagitis. We used the standard search strategy of the Cochrane Neonatal Review Group to search the Cochrane Central Register of Controlled Trials (CENTRAL 2016, Issue 2), MEDLINE via PubMed (1966 to 22 November 2016), Embase (1980 to 22 November 2016), and CINAHL (1982 to 22 November 2016). We also searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials. We included randomised controlled trials if they examined the effects of feed thickeners as compared to unthickened feeds (no treatment or placebo) in treating GOR in term infants up to six months of age or six months of corrected gestational age for those born preterm. Two review authors independently identified eligible studies from the literature search. Two review authors independently performed data extraction and quality assessments of the eligible studies. Differences in opinion were resolved by discussion with a third review author, and consensus was reached among all three review authors. We used the GRADE approach to assess the quality of the evidence. Eight trials recruiting a total of 637 infants met the inclusion criteria for the systematic review. The infants included in the review were mainly formula-fed term infants. The trials were of variable methodological quality. Formula-fed term infants with GOR on feed thickeners had nearly two fewer episodes of regurgitation per day (mean difference -1.97 episodes per day

Lifestyle measures in the management of gastro-oesophageal reflux disease: clinical and pathophysiological considerations.

2015-03-01

Several lifestyle and dietary factors are commonly cited as risk factors for gastro-oesophageal reflux disease (GORD) and modification of these factors has been advocated as first-line measures for the management of GORD. We performed a systematic review of the literature from 2005 to the present relating to the effect of these factors and their modification on GORD symptoms, physiological parameters of reflux as well as endoscopic appearances. Conflicting results existed for the association between smoking, alcohol and various dietary factors in the development of GORD. These equivocal findings are partly due to methodology problems. There is recent good evidence that weight reduction and smoking cessation are beneficial in reducing GORD symptoms. Clinical and physiological studies also suggest that some physical measures as well as modification of meal size and timing can also be beneficial. However, there is limited evidence for the role of avoiding alcohol and certain dietary ingredients including carbonated drinks, caffeine, fat, spicy foods, chocolate and mint.

Gastro-oesophageal reflux disease (GORD) is a very common paediatric disorder and the majority of patients are treated successfully by primary care physicians. Two infants aged 2 months with GORD which did not respond to conventional medical management are reported; they were diagnosed with duodenum inversum. The first infant failed medical management and required Nissen's fundoplication to control his symptoms. The second infant improved on maximizing medical management without the need for a surgical procedure. These two cases highlight the need for further work-up in patients who do not respond to conventional GORD therapy and/or present with atypical clinical symptoms.

Full Text Available Abstract Background Oestrogen and progestogen have the potential to influence gastro-intestinal motility; both are key components of hormone replacement therapy (HRT. Results of observational studies in women taking HRT rely on self-reporting of gastro-oesophageal symptoms and the aetiology of gastro-oesophageal reflux disease (GORD remains unclear. This study investigated the association between HRT and GORD in menopausal women using validated general practice records. Methods 51,182 menopausal women were identified using the UK General Practice Research Database between 1995–2004. Of these, 8,831 were matched with and without hormone use. Odds ratios (ORs were calculated for GORD and proton-pump inhibitor (PPI use in hormone and non-hormone users, adjusting for age, co-morbidities, and co-pharmacy. Results In unadjusted analysis, all forms of hormone use (oestrogen-only, tibolone, combined HRT and progestogen were statistically significantly associated with GORD. In adjusted models, this association remained statistically significant for oestrogen-only treatment (OR 1.49; 1.18–1.89. Unadjusted analysis showed a statistically significant association between PPI use and oestrogen-only and combined HRT treatment. When adjusted for covariates, oestrogen-only treatment was significant (OR 1.34; 95% CI 1.03–1.74. Findings from the adjusted model demonstrated the greater use of PPI by progestogen users (OR 1.50; 1.01–2.22. Conclusions This first large cohort study of the association between GORD and HRT found a statistically significant association between oestrogen-only hormone and GORD and PPI use. This should be further investigated using prospective follow-up to validate the strength of association and describe its clinical significance.

Background Pharyngeal pH probes and pH-impedance catheters have been developed for the diagnosis of laryngo-pharyngeal reflux. Objective To determine the reliability of pharyngeal pH alone for the detection of pharyngeal reflux events. Methods 24-h pH-impedance recordings performed in 45 healthy subjects with a bifurcated probe for detection of pharyngeal and oesophageal reflux events were reviewed. Pharyngeal pH drops to below 4 and 5 were analysed for the simultaneous occurrence of pharyngeal reflux, gastro-oesophageal reflux, and swallows, according to impedance patterns. Results Only 7.0% of pharyngeal pH drops to below 5 identified with impedance corresponded to pharyngeal reflux, while 92.6% were related to swallows and 10.2 and 13.3% were associated with proximal and distal gastro-oesophageal reflux events, respectively. Of pharyngeal pH drops to below 4, 13.2% were related to pharyngeal reflux, 87.5% were related to swallows, and 18.1 and 21.5% were associated with proximal and distal gastro-oesophageal reflux events, respectively. Conclusions This study demonstrates that pharyngeal pH alone is not reliable for the detection of pharyngeal reflux and that adding distal oesophageal pH analysis is not helpful. The only reliable analysis should take into account impedance patterns demonstrating the presence of pharyngeal reflux event preceded by a distal and proximal reflux event within the oesophagus.

The risk for acidic reflux is mainly determined by the position of the gastric acid pocket. It was hypothesised that compounds affecting proximal stomach tone might reduce gastro-oesophageal reflux by changing the acid pocket position. To study the effect of azithromycin (Azi) on acid pocket position and acid exposure in patients with gastro-oesophageal reflux disease (GORD). Nineteen patients with GORD were included, of whom seven had a large hiatal hernia (≥3 cm) (L-HH) and 12 had a small or no hiatal hernia (S-HH). Patients were randomised to Azi 250 mg/day or placebo during 3 days in a crossover manner. On each study day, reflux episodes were detected using concurrent high-resolution manometry and pH-impedance monitoring after a standardised meal. The acid pocket was visualised using scintigraphy, and its position was determined relative to the diaphragm. Azi reduced the number of acid reflux events (placebo 8.0±2.2 vs Azi 5.6±1.8, pacid exposure (placebo 10.5±3.8% vs Azi 5.9±2.5%, preflux episodes. Acid reflux occurred mainly when the acid pocket was located above, or at the level of, the diaphragm, rather than below the diaphragm. Treatment with Azi reduced hiatal hernia size and resulted in a more distal position of the acid pocket compared with placebo (below the diaphragm 39% vs 29%, p=0.03). Azi reduced the rate of acid reflux episodes in patients with S-HH (38% to 17%) to a greater extent than in patients with L-HH (69% to 62%, p=0.04). Azi reduces acid reflux episodes and oesophageal acid exposure. This effect was associated with a smaller hiatal hernia size and a more distal position of the acid pocket, further indicating the importance of the acid pocket in the pathogenesis of GORD. http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=1970 NTR1970.

Current diagnostic methods for gastro-oesophageal reflux disease (GORD) have moderate sensitivity/specificity and can be invasive and expensive. Pepsin detection in saliva has been proposed as an 'office-based' method for GORD diagnosis. The aims of this study were to establish normal values of salivary pepsin in healthy asymptomatic subjects and to determine its value to discriminate patients with reflux-related symptoms (GORD, hypersensitive oesophagus (HO)) from functional heartburn (FH). 100 asymptomatic controls and 111 patients with heartburn underwent MII-pH monitoring and simultaneous salivary pepsin determination on waking, after lunch and dinner. Cut-off value for pepsin positivity was 16 ng/mL. Patients were divided into GORD (increased acid exposure time (AET), n=58); HO (normal AET and + Symptom Association Probability (SAP), n=26) and FH (normal AET and-SAP, n=27). 1/3 of asymptomatic subjects had pepsin in saliva at low concentration (0(0-59)ng/mL). Patients with GORD and HO had higher prevalence and pepsin concentration than controls (HO, 237(52-311)ng/mL and GORD, 121(29-252)ng/mL)(p210 ng/mL pepsin suggested presence of GORD+HO with 98.2% specificity (likelihood ratio: 25.1). Only 18/84 (21.4%) of GORD+HO patients had 3 negative samples. In patients with symptoms suggestive of GORD, salivary pepsin testing may complement questionnaires to assist office-based diagnosis. This may lessen the use of unnecessary antireflux therapy and the need for further invasive and expensive diagnostic methods. Published by the BMJ Publishing Group Limited.

Obese children for unknown reasons report greater asthma symptoms. Asthma and obesity both independently associate with gastro-oesophageal reflux symptoms (GORS). Determining if obesity affects the link between GORS and asthma will help elucidate the obese-asthma phenotype. Extend our previous work to determine the degree of associations between the GORS and asthma phenotype. We conducted a cross-sectional study of lean (20%-65% body mass index, BMI) and obese (≥95% BMI) children aged 10-17 years old with persistent, early-onset asthma. Participants contributed demographics, GORS and asthma questionnaires and lung function data. We determined associations between weight status, GORS and asthma outcomes using multivariable linear and logistic regression. Findings were replicated in a second well-characterised cohort of asthmatic children. Obese children had seven times higher odds of reporting multiple GORS (OR=7.7, 95% CI 1.9 to 31.0, interaction p value=.004). Asthma symptoms were closely associated with GORS scores in obese patients (r=0.815, pgastro-oesophageal reflux and asthma symptoms suggests that misattribution of GORS to asthma may be a contributing mechanism to excess asthma symptoms in obese children.

To determine the influence of physiotherapy using intrapulmonary percussive ventilation on gastro-oesophageal reflux (GOR) in infants reflux episodes (RE) over a 20-min period was registered for each infant and a mean per 20 min was calculated in order to obtain a baseline value. The number of RE during IPV R intervention was compared to baseline. Fifty infants with a median age of 133 days were recruited of whom 21 were diagnosed with pathological GOR. During IPV R , the incidence of RE in the entire group was significantly lower compared to baseline; median (inter-quartile range [IQR]) 0 (0-1) versus 0.71 (0-1.33) RE, respectively, P = 0.003. The subgroup with abnormal GOR showed also a significant decrease of RE during IPV R ; median (IQR) 0 (0-1) versus 1.17 (0.55-2.16) RE, respectively, P = 0.03. No difference was detected in the group with normal reflux; median (IQR) 0.6 (0-1) compared to 0 (0-1) RE, respectively, P = 0.34. IPV R does not induce, nor aggravate GOR in infants without and with pathological GOR, respectively, but on the contrary decreases the number of RE in patients with pathological reflux.

Full Text Available Abstract Background In various people of the Western world, gastro-oesophageal reflux (GOR has been reported to be a common problem. Various studies have also assessed the relationship between GOR and dental erosion. The authors are not aware of such studies in Nigerians. It is therefore the aims of the present study to estimate the prevalence of GOR; to estimate the prevalence of dental erosion in patients with GORD; to document the oral findings in patients diagnosed with GORD and to compare these findings with previous studies elsewhere. Methods A total of 225 subjects comprising of 100 volunteers and 125 patients diagnosed with GORD were involved in this study. History of gastric juice regurgitation and heartburn were recorded. Oral examination to quantify loss of tooth structure was done using the tooth wear index (TWI designed by Smith and Knight (1984. Results Twenty patients with GORD presented with dental erosion in the maxillary anterior teeth with TWI scores ranging from 1–3. The prevalence of erosion was found to be statistically significant between GORD patients (16% and control (5% (p 0.05. Conclusion The present study supports the consideration of dental erosion as the extra-oesophageal manifestation of GORD. However the association between GORD and burning mouth sensation needs more investigation.

Both dental erosion and respiratory symptoms are extra-oesophageal manifestations of gastro-oesophageal reflux disease (GERD). The aim of this study was to determine whether dental erosion was correlated with respiratory symptoms in GERD patients. 88 GERD patients were recruited and assigned to three groups mainly according to the frequency of respiratory symptoms: Group I: never; Group II: occasional (1-2 days a week or less); Group III: frequent (3-5 days a week or more). All patients underwent medical evaluations, including medical history, questionnaire answering and alimentary tract examinations. Dental examinations were carried out on these patients and 36 healthy controls. Dental erosions were measured by modified method of Smith and Knight Tooth Wear Index (TWI). Location and severity of dental erosion were recorded. The prevalence of dental erosion in Group III (64.52%) was higher (pdental erosion with TWI scores ranging from 1 to 4. Though proportion of dental erosion with Score 2 (7/20) in Group III was higher than that in Group I (2/11) and Group II (3/12), there was no statistical significance in the proportions of erosion scores among three patient groups. Correlation coefficient between airway symptoms and scores of dental erosion was 0.231 (perosion of upper incisor was seen in 8 persons (72.7%) in Group I, 9 persons (75%) in Group II and 16 persons (80%) in Group III (p>0.05). Labial erosion of upper incisors was found in 1 person in Groups I and II respectively and 4 persons in Group III. All patients with labial erosion on upper incisors had palatal erosion, except 1 patient in Group III. In GERD patients, dental erosions are more prevalent in patients with frequent respiratory symptoms than those in patients with occasional and without respiratory symptoms. Palatal erosion of upper incisor is the main manifestation in patients. Acid reflux is the main causative factor of dental erosion in GERD patients with airway symptoms. Copyright © 2010

Gender differences may exist in the symptom experience of patients with gastro-oesophageal reflux disease (GERD) who have a partial response to proton pump inhibitors (PPIs). The purpose of this study was to analyse gender differences in partial responders to PPIs. Patients with GERD who responded partially to PPIs (n = 580; NCT00703534) completed the Reflux Symptom Questionnaire 7-day recall (RESQ-7) and the Gastrointestinal Symptom Rating Scale (GSRS). Anxiety and depression were evaluated using the Hospital Anxiety and Depression Scale. Women had significantly higher RESQ-7 domain scores than men for Heartburn (frequency: 4.3 vs 3.9; intensity: 3.1 vs 2.8), Burping (frequency: 4.9 vs 4.4; intensity: 3.1 vs 2.8) and Hoarseness, cough and difficulty swallowing (frequency: 2.6 vs 2.2; intensity: 1.8 vs 1.5), and had higher GSRS domain discomfort scores than men for Abdominal pain (3.51 vs 3.23), Indigestion (3.80 vs 3.45) and Constipation (2.69 vs 2.17) (all p < 0.05). Anxiety and depression were significantly more prevalent in women than in men. In this population of partial responders, women had more frequent/intense heartburn and extra-oesophageal symptoms and more discomfort from abdominal pain, indigestion and constipation than men. Comorbid anxiety and depression may contribute to the increased symptom burden in women.

Background The GerdQ scoring system may be a useful tool for managing gastro-oesophageal reflux disease. However, GerdQ has not been fully validated in Asian countries. Objective To validate the Japanese version of GerdQ and to compare this version to the Carlsson-Dent questionnaire (CDQ) in both general and hospital-based populations. Methods The questionnaires, including the Japanese versions of GerdQ and CDQ, and questions designed to collect demographic information, were sent to a general population via the web, and to a hospital-based population via conventional mail. The optimal cutoff GerdQ score and the differences in the characteristics between GerdQ and CDQ were assessed. Results The answers from 863 web-responders and 303 conventional-mail responders were analysed. When a GerdQ cutoff score was set at 8, GerdQ significantly predicted the presence of reflux oesophagitis. Although the GerdQ scores were correlated with the CDQ scores, the concordance rates were poor. Multivariate analysis results indicated that, the additional use of over-the-counter medications was associated with GerdQ score ≥ 8, but not with CDQ score ≥ 6. Conclusions The GerdQ cutoff score of 8 was appropriate for the Japanese population. Compared with CDQ, GerdQ was more useful for evaluating treatment efficacy and detecting patients’ unmet medical needs. PMID:24917957

The ENGIP-I study was conducted to investigate the efficacy, and safety of itopride in patients of gastro-oesophageal reflux disease. There were significant reductions in heartburn frequency, heartburn severity, gastro-oesophageal regurgitation frequency at day 3 only. ENGIP-I study concluded that itopride was well tolerated by patients and appears to be the drug of choice in patients with gastro-oesophageal reflux disease.

Single isotopic probe for gastro-esophageal reflux diagnosis in children

Gastro-esophageal reflux (GER) in children has been implicated in various recurring respiratory diseases. Several techniques including oesophageal pH testing and scintigraphy have been devised to detect and quantify GER Limitations have been found for each test: short duration with gamma-camera and restricted acceptability of the pH probe by children. A single isotopic probe was designed for a non-invasive screening test of GER in infants. This device was checked by comparison with oesophageal scintigraphy using a gamma camera. Only 1 discrepancy was detected in 19 reflux episodes. This method, using a relatively inexpensive detector and data acquisition module, seems to be well accepted by children, and may be associated with a pH probe for GER diagnosis.

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 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.

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 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.

Diagnosing gastro-oesophageal reflux disease or lactose intolerance in babies who cry a lot in the first few months overlooks feeding problems.

Science.gov (United States)

Douglas, Pamela Sylvia

2013-04-01

This paper explores two areas in which the translation of research into practice may be improved in the management of cry-fuss behaviours in the first few months of life. Firstly, babies who cry excessively are often prescribed proton pump inhibitors, despite evidence that gastro-oesophageal reflux disease is very rarely a cause. The inaccuracy of commonly used explanatory mechanisms, the side-effects of acid-suppressive medications, and the failure to identify treatable problems, including feeding difficulty when the diagnosis of 'reflux' is applied, are discussed. Secondly, crying breastfed babies are still prescribed lactase or lactose-free formula, despite evidence that the problem of functional lactose overload is one of breastfeeding management. The mechanisms and management of functional lactose overload are discussed. These two problems of research translation need to be addressed because failure to identify and manage other causes of cry-fuss problems, including feeding difficulty, may have adverse outcomes for a small but significant minority of families. © 2013 The Author.

We describe here a new mapping method able to find out connectivity traces among variables thanks to an artificial adaptive system, the Auto Contractive Map (AutoCM), able to define the strength of the associations of each variable with all the others in a dataset. After the training phase, the weights matrix of the AutoCM represents the map of the main connections between the variables. The example of gastro-oesophageal reflux disease data base is extremely useful to figure out how this new approach can help to re-design the overall structure of factors related to complex and specific diseases description.

Proton pump inhibitor failure in gastro-oesophageal reflux disease: a perspective aided by the Gartner hype cycle.

Science.gov (United States)

Heading, Robert C

2017-04-01

Some patients with gastro-oesophageal reflux disease (GORD) experience symptoms despite proton pump inhibitor (PPI) treatment. In the early years of their availability, these drugs were thought to be a highly effective treatment for GORD and realisation that symptom relief was often incomplete came as a disappointment. This review considers the evolution of thinking with the aid of the Gartner hype cycle - a graphical depiction of the process of innovation, evolution and adoption of new technologies. Acknowledging that over-simplistic concepts of GORD have been largely responsible for inflated expectations of PPI therapy is an important step forward in establishing how patients with persistent symptoms, despite PPIs, should be assessed and treated. © Royal College of Physicians 2017.

Rumination syndrome: when the lower oesophageal sphincter rises.

Rumination syndrome is an uncommon condition characterised by the self-induced regurgitation from the stomach to the mouth of recently ingested meal that is chewed and reswallowed. Rumination is caused by a voluntary rise in intra-abdominal and intra-gastric pressure leading to the reflux of the gastric content into the oesophagus. However, the precise mechanisms preventing reflux at the gastro-oesophageal junction during the rise in intra-gastric pressure remains unknown. In 5 patients, rumination episodes were monitored using combined multiple intra-luminal impedance monitoring, high resolution manometry, and video-fluoroscopic recording. We showed that the gastro-oesophageal junction moved from the abdominal cavity into the thorax creating a "pseudo-hernia". This occurred at a range of 1.4 ± 0.3 s before the rise in intra-oesophageal pressure and the gastro-oesophageal reflux. This displacement of the gastro-oesophageal junction into thorax, rather than a lower oesophageal sphincter opening, explains the mechanism of voluntary regurgitations occurring during rumination syndrome.

Introduction: Functional dyspepsia and non-erosive reflux disease (NERD) are prevalent gastrointestinal conditions with accumulating evidence regarding an overlap between the two. Still, patients with NERD represent a very heterogeneous group and limited data on dyspeptic symptoms in various subgroups of NERD are available. Aim: To evaluate the prevalence of dyspeptic symptoms in patients with NERD subclassified by using 24 h impedance-pH monitoring (MII-pH). Methods: Patients with typical reflux symptoms and normal endoscopy underwent impedance-pH monitoring off proton pump inhibitor treatment. Oesophageal acid exposure time (AET), type of acid and non-acid reflux episodes, and symptom association probability (SAP) were calculated. A validated dyspepsia questionnaire was used to quantify dyspeptic symptoms prior to reflux monitoring. Results: Of 200 patients with NERD (105 female; median age, 48 years), 81 (41%) had an abnormal oesophageal AET (NERD pH-POS), 65 (32%) had normal oesophageal AET and positive SAP for acid and/or non-acid reflux (hypersensitive oesophagus), and 54 (27%) had normal oesophageal AET and negative SAP (functional heartburn). Patients with functional heartburn had more frequent (pheartburn reinforces the concept that functional gastrointestinal disorders extend beyond the boundaries suggested by the anatomical location of symptoms. This should be regarded as a further argument to test patients with symptoms of gastro-oesophageal reflux disease in order to separate patients with functional heartburn from patients with NERD in whom symptoms are associated with gastro-oesophageal reflux.

Patients with non-erosive reflux disease (NERD) have impaired oesophageal mucosal integrity (dilated intercellular spaces). Oesophageal mucosal integrity reflects the balance between repeated reflux damage and mucosal recovery. The relationship between mucosal integrity and acid sensitivity is unclear. Oesophageal impedance may be used for in vivo mucosal integrity measurement. We studied acid-induced changes in oesophageal mucosal integrity and acid perception in patients with heartburn. 50 patients with heartburn whithout oesophagitis underwent impedance monitoring before, during and after 10 min oesophageal perfusion with neutral (pH 6.5) and acid solutions (pH 1). Symptoms and impedance were recorded during perfusion. Impedance recovery was assessed for 2 h post-perfusion in ambulatory conditions followed by 24-h impedance-pH study. Reflux monitoring discriminated 20 NERD and 30 functional heartburn (FH) patients. Neutral perfusion caused impedance fall that recovered within 10 min. Acid perfusion caused impedance fall with slow recovery: 6.5 Ω/min (IQR 3.3-12.0 Ω/min). Patients with slow recovery (acid sensitivity (10/12 vs. 4/12, p = 0.04) than those with fast (> 75th percentile) recovery. Patients with NERD had lower baseline impedance (1669 ± 182 Ω vs. 2384 ± 211 Ω, p = 0.02) and slower impedance recovery (6.0 ± 0.9 Ω/min vs. 10.7 ± 1.6 Ω/min, p = 0.03) than patients with FH. Impaired mucosal integrity might be the consequence of repeated reflux episodes with slow recovery. Mucosal integrity, recovery capacity and symptom perception are linked. Low basal impedance and slow recovery after acid challenge are associated with increased acid sensitivity.

Prevalence of gastro-oesophageal reflux disease symptoms and reflux-associated respiratory symptoms in asthma

Science.gov (United States)

2010-01-01

Background Gastro-oesophageal reflux disease (GORD) symptoms are common in asthma and have been extensively studied, but less so in the Asian continent. Reflux-associated respiratory symptoms (RARS) have, in contrast, been little-studied globally. We report the prevalence of GORD symptoms and RARS in adult asthmatics, and their association with asthma severity and medication use. Methods A cross-sectional analytical study. A validated interviewer-administered GORD scale was used to assess frequency and severity of seven GORD symptoms. Subjects were consecutive asthmatics attending medical clinics. Controls were matched subjects without respiratory symptoms. Results The mean (SD) composite GORD symptom score of asthmatics was significantly higher than controls (21.8 (17.2) versus 12.0 (7.6); P < 0.001) as was frequency of each symptom and RARS. Prevalence of GORD symptoms in asthmatics was 59.4% (95% CI, 59.1%-59.6%) versus 28.5% in controls (95% CI, 29.0% - 29.4%). 36% of asthmatics experienced respiratory symptoms in association with both typical and atypical GORD symptoms, compared to 10% of controls (P < 0.001). An asthmatic had a 3.5 times higher risk of experiencing a GORD symptom after adjusting for confounders (OR 3.5; 95% CI 2.5-5.3). Severity of asthma had a strong dose-response relationship with GORD symptoms. Asthma medication use did not significantly influence the presence of GORD symptoms. Conclusions GORD symptoms and RARS were more prevalent in a cohort of Sri Lankan adult asthmatics compared to non-asthmatics. Increased prevalence of RARS is associated with both typical and atypical symptoms of GORD. Asthma disease and its severity, but not asthma medication, appear to influence presence of GORD symptoms.

Fransson, S.G.; Soekjer, H.; Johansson, K.E.; Tibbling, L.

In a follow-up after fundoplication, 61 patients underwent a double contrast examination of the stomach and a radiologic examination to detect any gastro-oesophageal reflux. The radiologic findings were compared with pH reflux test and symptoms. Gastro-oesophageal reflux was found in 7 patients at radiologic examination. None of these patients had an adequate fundoplication at a double contrast examination of the stomach and all had symptoms indicating reflux. Recurrence of gastro-oesophageal reflux may be shown at the radiologic examination and predicted by the morphologic appearances at the double contrast examination.

The alginate-antacid, Gaviscon Double Action (Gaviscon DA; Reckitt Benckiser, Slough, UK) suppresses reflux after meals by creating a gel-like barrier that caps and displaces the acid pocket distal to the oesophago-gastric junction. The effect of Gaviscon DA on reflux and dyspepsia symptoms has not yet been demonstrated with a modern trial design. A pilot study to assess the efficacy and safety of Gaviscon DA compared with matched placebo for decreasing upper gastrointestinal symptoms in symptomatic gastro-oesophageal reflux disease (GERD) patients. A randomised, double-blind, parallel group study was performed in 110 patients with symptoms of GERD. Patients received Gaviscon DA or placebo tablets for 7 consecutive days. The primary endpoint compared the change in overall Reflux Disease Questionnaire (RDQ) symptom score (combined heartburn/regurgitation/dyspepsia). Secondary endpoints assessed individual dimensions, GERD dimension (heartburn and regurgitation) and overall treatment evaluation (OTE). There was a greater decrease in overall RDQ symptom score in the Gaviscon DA group compared with the placebo group (Least Squares Mean difference -0.55; P = 0.0033), and for each of the dimensions independently. Patients in the Gaviscon DA group evaluated their overall treatment response higher than patients in the placebo group [mean (standard deviation) OTE 4.1 (2.44) vs. 1.9 (3.34); P = 0.0005]. No differences in the incidence of adverse events were observed between treatment groups. Gaviscon DA decreases reflux and dyspeptic symptoms in GERD patients compared with matched placebo and has a favourable benefit-risk balance. Larger scale clinical investigations of medications targeting the acid pocket are warranted. (EudraCT, 2012-002188-84). © 2014 John Wiley & Sons Ltd.

BACKGROUND: Guidelines recommend that patients with gastro-oesophageal reflux disease are adequately treated with acid-suppressive therapy before undergoing anti-reflux surgery. Little is known of the use of acid-suppressive drugs before anti-reflux surgery. AIM: To determine the use of proton pump...... inhibitors and H2 -receptor antagonists in the year before anti-reflux surgery. METHODS: A nationwide retrospective study of all patients aged ≥18 undergoing first-time anti-reflux surgery in Denmark during 2000-2012 using data from three different sources: the Danish National Register of Patients......, the Danish National Prescription Register, and the Danish Person Register. RESULTS: The study population thus included 2922 patients (median age: 48 years, 55.7% male). The annual proportion of patients redeeming ≥180 DDD of acid-suppressive therapy increased from 17.0% 5 years before anti-reflux surgery...

Patients with refractory respiratory symptoms related to gastro-oesophageal reflux disease (GORD) such as asthma and cough are being referred for laparoscopic fundoplication (LFP), as recommended by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES). However there are limited data regarding symptomatic response to fundoplication in this group of patients. A 7 year retrospective review was performed to study the efficacy of LFP in the treatment of patients with respiratory manifestations of GORD. Patients were followed up from 4 to 6 weeks (short-term) to 6-12 months (long-term) post-operatively. Of 208 patients who underwent LFP, 73 (35%) patients were eligible for inclusion into the study. 55 (75%) patients had improved respiratory symptoms at short-term follow-up. At long-term follow-up, 7 of these patients had recurrence of respiratory symptoms, while 4 patients had improvement not initially apparent. No significant predictive factor for the success or failure of surgery was identified. 190 (91%) of 208 patients had symptomatic improvement in GORD at short-term follow-up. LFP is effective with the response rates over 75% in the control of respiratory manifestation of GORD, compared to over 91% response rate in the control GOR symptoms alone. More research is needed to identify factors to aid patient selection to improve response rate. Copyright © 2014 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

This 2015 study investigated whether Lebanese paediatricians diagnosed and managed gastro-oesophageal reflux disease (GERD) in infants and children in accordance with the 2009 guidelines from the North American and European Societies for Paediatric Gastroenterology, Hepatology and Nutrition. Paediatricians members of the Lebanese Order of Physicians with updated email addresses were invited to complete a web-based survey between September and November 2015, to assess their knowledge and management of GERD. Responses were received from 114 of the 543 paediatricians, and 96 were analysed. Only two respondents complied fully with the international guidelines. The majority diagnosed GERD in infants based solely on their medical history and examination. Moreover, nearly two-thirds of the respondents would start an empiric trial with acid suppression. Around half of the respondents considered proton pump inhibitors to be the mainstay of GERD treatment. This was the first Lebanese study that surveyed the management of paediatric GERD. Only 2.1% of the paediatricians followed the guidelines on the evidence-based management of GERD. This highlights the need for studies to assess barriers to guideline implementation and the development of new guidelines accounting for regional factors, mainly the cost of investigations and prevalence of medical insurance. ©2016 Foundation Acta Paediatrica.

Using scintigraphic techniques oesophageal transit was studied in 47 patients and gastro-oesophageal reflux was evaluated in 41 patients. The comparison of these investigations with oesophageal manometry, acid reflux test and endoscopy emphasized the value of the simple and noninvasive scintigraphic methods. Radionuclide oesophageal transit detected a higher incidence of esophageal motor abnormality than the other methods. Gastroesophageal (GE) scintiscanning detected GE reflux accurately, rapidly and with greater sensitivity than the other diagnostic techniques.

Itopride is a new prokinetic agent that combines antidopaminergic and cholinesterase inhibitory actions. Previous studies suggested that itopride improves heartburn in functional dyspepsia, and decreases oesophageal acid exposure in gastro-oesophageal reflux disease. It remains unclear whether this effect is due to effects of itopride on the lower oesophageal sphincter (LES). To study the effects of itopride on fasting and postprandial LES function in healthy subjects. Twelve healthy volunteers (five men; 32.6 ± 2.0 years) underwent three oesophageal sleeve manometry studies after 3 days premedication with itopride 50 mg, itopride 100 mg or placebo t.d.s. Drug was administered after 30 min and a standardized meal was administered after 90 min, with measurements continuing to 120 min postprandially. Throughout the study, 10 wet swallows were administered at 30-min intervals, and gastrointestinal symptoms were scored on 100 mm visual analogue scales at 15-min intervals. Lower oesophageal sphincter resting pressures, swallow-induced relaxations and the amplitude or duration of peristaltic contractions were not altered by both doses of itopride, at all time points. Itopride pre-treatment inhibited the meal-induced rise of transient LES relaxations (TLESRs). Itopride inhibits TLESRs without significantly affecting oesophageal peristaltic function or LES pressure. These observations support further studies with itopride in gastro-oesophageal reflux disease. © 2010 Blackwell Publishing Ltd.

Objective: To compare the sensitivity of gastro-oesophageal reflux (GOR) scintigraphy at 5-s and 60-s frame acquisition rates. Methods: GOR scintigraphy of 50 subjects (1 month–20 years old, mean 42 months) were analysed concurrently using 5-s and 60-s acquisition frames. Reflux episodes were graded as low if activity was detected in the distal half of the oesophagus and high if activity was detected in its upper half or in the oral cavity. For comparison purposes, detected GOR in any number of 5-s frames corresponding to one 60-s frame was counted as one episode. Results: A total of 679 episodes of GOR to the upper oesophagus were counted using a 5-s acquisition technique. Only 183 of such episodes were detected on 60-s acquisition images. To the lower oesophagus, a total of 1749 GOR episodes were detected using a 5-s acquisition technique and only 1045 episodes using 60-s acquisition frames (these also included the high-level GOR on 5-s frames counted as low level on 60-s acquisition frames). 10 patients had high-level GOR episodes that were detected only using a 5-s acquisition technique, leading to a different diagnosis in these patients. No correlation between the number of reflux episodes and the gastric emptying rates was noted. Conclusion: The 5-s frame acquisition technique is more sensitive than the 60-s frame acquisition technique for detecting both high- and low-level GOR. Advances in knowledge: Brief GOR episodes with a relatively low number of radioactive counts are frequently indistinguishable from intense background activity on 60-s acquisition frames.

Full Text Available Abstract Background Proton pump inhibitor (PPI medication and surgical fundoplication are used for the control of gastro-oesophageal reflux in patients with Barrett's oesophagus, but differ in their effectiveness for both acid and bile reflux. This might impact on the inflammatory processes that are associated with progression of Barrett's oesophagus to cancer, and this may be evident in the gene expression profile and microRNA expression pattern in Barrett's oesophagus mucosa. We hypothesised that two miRNAs with inflammatory and oncogenic roles, miR-101 and miR-196a, are differentially expressed in Barrett's oesophagus epithelium in patients with reflux treated medically vs. surgically. Findings Mucosal tissue was obtained at endoscopy from patients with Barrett's oesophagus whose reflux was controlled by proton pump inhibitor (PPI therapy (n = 20 or by fundoplication (n = 19. RNA was extracted and the expression of miR-101 and miR-196a was measured using real-time reverse transcription - polymerase chain reaction. There were no significant differences in miR-101 and miR-196a expression in Barrett's oesophagus epithelium in patients treated by PPI vs. fundoplication (p = 0.768 and 0.211 respectively. Secondary analysis showed a correlation between miR-196a expression and Barrett's oesophagus segment length (p = 0.014. Conclusion The method of reflux treatment did not influence the expression of miR-101 and miR-196a in Barrett's oesophagus. This data does not provide support to the hypothesis that surgical treatment of reflux better prevents cancer development in Barrett's oesophagus. The association between miR-196a expression and Barrett's oesophagus length is consistent with a tumour promoting role for miR-196a in Barrett's oesophagus.

Full Text Available Abstract Background Gastro-oesophageal reflux disease (GERD is a common disorder with consequences for the patient's health-related quality of life (HRQoL. In Germany, few data are available on the impact of GERD on work-related productivity. Aim To study the impact of GERD on work productivity despite proton pump inhibitor (PPI therapy and the association between productivity and symptom duration, severity, and HRQoL. Methods Retrospective data from randomly selected patients with chronic GERD symptoms, treated by office-based general practitioners or general internists with routine clinical care, were analyzed together with information from self-administered instruments assessing work productivity (WPAI-GERD, symptoms (RDQ, and HRQoL (QOLRAD. Results Reduced productivity was reported by 152 of 249 patients (61.0%, although 89.5% of them were treated with PPI. The reduction in work productivity was 18.5% in all patients and 30.3% in those with reduced productivity. Patients with impaired productivity showed a significantly lower HRQoL and more-severe symptoms of reflux disease. In all patients, the mean sick leave attributable to reflux symptoms was 0.6 hours in the previous seven days and 1.4 work days in the previous three months. Conclusion GERD has a substantial impact on work productivity in Germany, even in patients receiving routine clinical care and PPI therapy.

Pantoprazole magnesium (pantoprazole-Mg) may display extended inhibition of the proton pump with the potential for improved clinical efficacy in gastro-oesophageal reflux disease (GERD). To compare the efficacy of pantoprazole-Mg and esomeprazole in GERD. Gastro-oesophageal reflux disease (Los Angeles grades A-D) patients were randomised to 4 weeks of treatment with pantoprazole-Mg (n = 290) or esomeprazole (n = 288), both 40 mg once daily, in this multicentre (14 Brazilian sites in 9 cities), double-blind study, with an additional 4 weeks' treatment in nonresponding patients. Severity of oesophagitis (at endoscopy) and GERD-related symptoms (ReQuest-GI) were assessed. The primary end point was the proportion of patients in complete remission (ReQuest-GI score <1.73 plus endoscopic healing) at week 4. Complete remission occurred in 61% of patients in each treatment group at 4 weeks (primary endpoint) and in 81% and 79% of patients in the pantoprazole-Mg and esomeprazole groups at 8 weeks, with no significant differences. Mucosal healing rates were high and not significantly different. At 8 weeks, symptom relief with pantoprazole-Mg was significantly greater than that with esomeprazole (91.6% vs. 86.0%, P = 0.0370) because of continued improvement in symptoms with pantoprazole-Mg from week 4 to week 8 (P = 0.0206). Pantoprazole-Mg 40 mg was at least as effective as esomeprazole 40 mg for complete remission and the mucosal healing rate was high. Symptom relief with pantoprazole-Mg continued to improve from 4 to 8 weeks and was greater than that with esomeprazole at week 8, suggesting an extended period of treatment effect (ClinicalTrials.gov identifier: NCT01132638). © 2013 John Wiley & Sons Ltd.

Nighttime heartburn, common among patients with gastro-oesophageal reflux disease (GERD), is associated with substantial clinical effects. GERD-related sleep disturbances are underappreciated and undertreated. To evaluate the efficacy of esomeprazole on GERD-related nighttime heartburn and associated sleep disturbances. In this multicentre, randomized, double-blind, placebo-controlled study, patients with moderate-to-severe nighttime heartburn and GERD-related sleep disturbances (endoscopies not required) received esomeprazole 20 mg or placebo each morning for 4 weeks. Heartburn symptoms and GERD-related sleep disturbances were evaluated using the validated Pittsburgh Sleep Quality Index and validated Work Productivity and Activity Impairment Questionnaire. The analysis included 262 patients (esomeprazole, n = 137; placebo, n = 125). Significantly more patients receiving esomeprazole achieved nighttime heartburn relief (primary end point) than those receiving placebo (34.3% vs. 10.4%; P heartburn and GERD-related sleep disturbances, improving heartburn symptoms, sleep quality, work productivity and functionality.

The aim of this study was to analyse the impact of hiatal hernia repair (HHR) on gastro-oesophageal reflux disease (GERD) in morbidly obese patients with hiatus hernia undergoing laparoscopic sleeve gastrectomy (LSG). It is a retrospective study involving ten morbidly obese patients with large hiatus hernia diagnosed on pre-operative endoscopy who underwent LSG and simultaneous HHR. The patients were assessed for symptoms of GERD using a Severity symptom score (SS) questionnaire and anti-reflux medications. Of the ten patients, five patients had GERD preoperatively. At the mean follow-up of 11.70 ± 6.07 months after surgery, four patients (80%) showed complete resolution while one patient complained of persistence of symptoms. Endoscopy in this patient revealed resolution of esophagitis indicating that the persistent symptoms were not attributable to reflux. The other five patients without GERD remained free of any symptom attributable to GERD. Thus, in all ten patients, repair of hiatal hernia (HH) during LSG led to either resolution of GERD or prevented any new onset symptom related to GER. In morbidly obese patients with HH with or without GERD undergoing LSG, repair of the hiatus hernia helps in amelioration of GERD and prevents any new onset GER. Thus, the presence of HH should not be considered as a contraindication for LSG.

To determine factors, overall and by sex, associated with self-reported gastro-oesophageal reflux disease (GORD) in chronic obstructive pulmonary disease (COPD) patients, and to evaluate relationships between GORD, its modification by acid suppression medications (Proton Pump Inhibitors [PPI]/histamine-2 receptor antagonists [H2RA]) and exacerbations of COPD and mortality. Logistic regression was used to determine factors associated with GORD; Cox proportional hazards models were used to calculate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for GORD and risk of exacerbation and death. Among 2135 COPD patients from the ECLIPSE cohort, 547 patients self-reported GORD, with female preponderance; 237 were taking PPI/H2RA. Risk factors for GORD did not differ by sex. When compared to patients who did not report GORD or use of PPI/H2RA, patients with GORD and taking PPI/H2RA had a significantly increased risk of exacerbation (HR = 1.58, 95%CI = 1.35-1.86); risk was also increased for patients reporting GORD only or PPI/H2RA use only (HR = 1.21 [1.04-1.40] and 1.33 [1.08-1.65], respectively). Similar findings were observed for risk of hospitalised exacerbation. GORD was not associated with mortality. GORD in COPD patients is highly prevalent, and risk factors did not differ by sex. Use of PPI/H2RA and self-reported GORD were associated with increased risk of moderate-to-severe and hospitalised exacerbations. Copyright © 2015 Elsevier Ltd. All rights reserved.

Laparoscopic partial fundoplication for gastro-oesophageal reflux disease (GORD) is reported to have fewer side effects when compared to Nissen fundoplication, but doubts remain over its long term durability in controlling reflux. The aim of this study was to assess outcome of symptoms for all patients presenting with GORD undergoing routine laparoscopic subtotal Lind fundoplication. All patients undergoing laparoscopic fundoplication between August, 1999 and November, 2007 performed by a single surgeon were included in the study. The anti-reflux procedure studied was laparoscopic Lind (300°) fundoplication with crural repair in all cases. Patients completed pre and post-operative questionnaires containing validated scoring systems for heartburn, gas bloat, dysphagia and overall patient satisfaction. Over the 100-month period, 320 consecutive patients underwent laparoscopic subtotal Lind fundoplication. Of these, 256 (80%) replied to the questionnaire at a mean of 31 months (range 3-96 months) following surgery. 91.4% of respondents had an improvement in heartburn symptom score with a significant reduction in score from 7.74 preoperatively to 1.25 postoperatively (preflux control (heartburn and regurgitation) from 3.49 preoperatively to 1.48 after surgery (preflux symptoms with half of these reporting their recurrence within two years following surgery. Because of this all were tested with post-operative pH testing, yet only one had a 24-h pH time outside the normal range. Overall patient satisfaction was high with a visual analogue score of 9 and 88% of the patients claimed they would have the operation again. Laparoscopic Lind fundoplication demonstrates excellent reflux control when performed routinely for all patients presenting with GORD. This technique is both durable and efficacious in controlling reflux symptoms. Copyright © 2014 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

Don't eat tomatoes: patient's self-reported experiences of causes of symptoms in gastro-oesophageal reflux disease.

About 30-50% of patients with gastro-oesophageal reflux disease (GORD) experience refractory symptoms despite taking proton pump inhibitors regularly. Epidemiology studies suggest lifestyle risks, but these are under-represented in existing guidelines. The potential for changes to positively impact on symptoms may be underestimated. Lifestyle advice currently appears to be ineffective. To inform the future design of a behaviour change intervention aimed at improving symptoms for patients with GORD, by exploring patient understanding and experiences of lifestyle influences on GORD symptoms. We conducted semi-structured interviews with 23 patients (12 women and 11 men) aged 30-86 years, aiming to identify lifestyle influences perceived by patients to affect their symptoms. Patients reported a wide range of daily influences on their symptoms, including diet, drinking with a meal, body position, alcohol, gaining weight, stress and anxiety. Dietary influences included types of food eaten and eating pattern-including speed of eating and meal size. Many foods were identified as troublesome, but not all foods affected all patients. Eating late and daytime tiredness were not recognized as causes or consequences of night-time reflux. Patients stated that daily living patterns affected their reflux symptoms, but influences were highly variable between respondents. Lifestyle factors appear to combine in unique patterns for individuals, but GORD patients may not be able to identify potential triggers and make changes for themselves. A behaviour change intervention might prove beneficial to these patients.

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.

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

Upper gastrointestinal symptoms impose a substantial illness burden and management costs. Understanding perceptions and reasons for seeking healthcare is a prerequisite for meeting patients' needs effectively. To review systematically findings on consultation frequencies for gastro-oesophageal reflux disease (GERD) and dyspepsia and patients' reasons for consultation. Systematic literature searches. Reported consultation rates ranged from 5.4% to 56% for GERD and from 26% to 70% for dyspepsia. Consultation for GERD was associated with increased symptom severity and frequency, interference with social activities, sleep disturbance, lack of timetabled work, higher levels of comorbidity, depression, anxiety, phobia, somatization and obsessionality. Some consulted because of fears that their symptoms represented serious disease; others avoided consultation because of this. Inconsistent associations were seen with medication use. Patients were less likely to consult if they felt that their doctor would trivialize their symptoms. Few factors were consistently associated with dyspepsia consultation. However, lower socio-economic status and Helicobacter pylori infection were associated with increased consultation. Patients' perceptions of their condition, comorbid factors and external reasons such as work and social factors are related to consultation rates for GERD. Awareness of these factors can guide the clinician towards a more effective strategy than one based on drug therapy alone.

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.

Gastro-oesophageal reflux disease (GORD) is a common obesity-related co-morbidity that is assessed objectively by 24-h pH monitoring. Some concerns have been raised regarding the risk of de novo GORD or exacerbation of pre-existing GORD after laparoscopic sleeve gastrectomy. Here, 24-h pH monitoring was used to assess the influence of laparoscopic sleeve gastrectomy on postoperative GORD in obese patients with or without preoperative GORD. From July 2012 to September 2014, all patients scheduled for laparoscopic sleeve gastrectomy were invited to participate in a prospective follow-up. Patients who underwent preoperative 24-h pH monitoring were asked to repeat the examination 6 months after operation. GORD was defined as an oesophageal pH < 4 for at least 4·2 per cent of the total time recorded. Of 89 patients, 76 had preoperative pH monitoring for GORD evaluation and 50 had postoperative reassessment. Patients without (group 1, 29 patients) or with (group 2, 21 patients) preoperative GORD were similar regarding age, sex ratio and body mass index. In group 1, the median (i.q.r.) total time at pH < 4 was significantly higher after surgery than before: 5·6 (2·5-9·5) versus 1·6 (0·7-2·9) per cent (P < 0·001). Twenty of the 29 patients experienced de novo GORD as determined by 24-h pH monitoring (P < 0·001). In group 2, total time at pH < 4 after surgery was no different from the preoperative value: 5·9 (3·9-10·7) versus 7·7 (5·2-10·3) per cent (P = 0·296). Laparoscopic sleeve gastrectomy was associated with de novo GORD in over two-thirds of patients, but did not seem to exacerbate existing GORD. © 2016 BJS Society Ltd Published by John Wiley & Sons Ltd.

Twenty-one patients whose condition required mechanical ventilation with nasogastric intubation were investigated for oesophagitis before the 3rd day and on the 15th day of treatment, including endoscopy and biopsy. Lesions of oesophagitis were detected in 14 cases during the initial examination and in 19 cases on the second endoscopy. The course of the lesions varied from one patient to another and appeared to be unrelated to the course of the primary disease. Oesophagitis in these patients is probably due to frequent episodes of gastro-oesophageal reflux encouraged by cough, impaired consciousness and the presence of a tube. Reflux may also be the cause of inapparent and recurrent lung aspiration.

Helicobacter pylori is associated with gastritis, peptic ulcers and gastric malignancies. Little attention has been paid to the possibility that it may also have a role in the pathogenesis of reflux oesophagitis. This is especially true in elderly patients who have life-long infection and provide an ideal group to study the mucosal changes associated with the organism. The aim of this study was to determine if H pylori is associated with reflux oesophagitis in elderly patients. Consecutive gastroscopy patients were recruited. Multiple biopsies were taken from oesophagus, stomach, antrum and duodenum for histology and rapid urease tests. Patients also had IgG ELISA antibodies and 13C-urea breath tests performed. Patients with macroscopic or microscopic evidence of reflux oesophagitis were compared to patients with macroscopically normal upper gastrointestinal tracts and no microscopic evidence of reflux. A total of 114 patients were recruited, average age 78.9 years (+/- 5.4). There were 37 refluxers and 33 non-refluxers. We found no evidence for an association between the presence of H pylori and reflux oesophagitis in elderly patients. The high prevalence of H pylori in patients with reflux oesophagitis can be explained by the presence of incidental gastritis. PMID:8733530

Nocturnal gastro-oesophageal reflux (nGOR) is associated with asthma and obstructive sleep apnoea (OSA). Our aim was to investigate whether nGOR is a risk factor for onset of asthma and onset of respiratory and OSA symptoms in a prospective population-based study. We invited 2640 subjects from Iceland, Sweden and Belgium for two evaluations over a 9-year interval. They participated in structured interviews, answered questionnaires, and underwent spirometries and methacholine challenge testing. nGOR was defined by reported symptoms. Subjects with persistent nGOR (n=123) had an independent increased risk of new asthma at follow-up (OR 2.3, 95% CI 1.1-4.9). Persistent nGOR was independently related to onset of respiratory symptoms (OR 3.0, 95% CI 1.6-5.6). The risk of developing symptoms of OSA was increased in subjects with new and persistent nGOR (OR 2.2, 95% CI 1.3-1.6, and OR 2.0, 95% CI 1.0-3.7, respectively). No significant association was found between nGOR and lung function or bronchial responsiveness. Persistent symptoms of nGOR contribute to the development of asthma and respiratory symptoms. New onset of OSA symptoms is higher among subjects with symptoms of nGOR. These findings provide evidence that nGOR may play a role in the genesis of respiratory symptoms and diseases.

Gastro-oesophageal reflux disease (GORD) is suggested to cause or aggravate several respiratory conditions. Studies with proton pump inhibitors have resulted in only minor improvements in pulmonary outcomes in patients with GORD. It has been speculated that operative treatment of GORD might be more efficient as it also diminishes non-acidic reflux. To compare the effects of esomeprazole 40 mg bid and fundoplication on airway responsiveness, forced expiratory volume in 1 s (FEV1), exhaled nitric oxide (NO) and respiratory symptoms in patients with moderate-to-severe GORD. Sixty-nine GORD patients had methacholine inhalation challenge performed on them, and FEV1, exhaled NO and respiratory symptoms were measured at baseline, after a 3-month treatment with esomeprazole and 3 months after fundoplication. Primary outcome variable was dose-response slope (DRS), i.e. decline in FEV1 during methacholine challenge divided with the amount of methacholine administered (%/μmol). Pre-defined subgroup analysis was performed among those with concomitant asthma (n = 12). There was no improvement in DRS, FEV1 or exhaled NO after esomeprazole treatment or fundoplication. Cough and dyspnoea measured with visual analog scale improved with esomeprazole treatment (P < 0.001), and further after fundoplication (P < 0.001). Among those with concomitant asthma, significant improvements in St George Respiratory Questionnaire (SGRQ) scores could be seen after fundoplication. Neither esomeprazole treatment nor fundoplication diminishes airway responsiveness or exhaled NO, or improves FEV1 in patients with GORD. Improvements in respiratory symptoms and SGRQ scores after GORD treatments could be detected. However, as this was not a placebo-controlled study, the findings in these secondary endpoints should not be emphasised. ClinicalTrials.cov: NCT00994708. © 2012 John Wiley & Sons Ltd.

To investigate the potential association of increased blood progesterone (P4 ) concentrations and/or late pregnancy with the incidence of gastro-oesophageal reflux (GOR), in healthy bitches undergoing ovariohysterectomy under general anaesthesia during anoestrus or dioestrus or during the second half of pregnancy. Prospective observational study. Ninety-four healthy, female, dogs, aged 1-8 years presented for elective ovariohysterectomy. Non-pregnant animals were classified into group A (anoestrus) (n = 35) if blood P4 concentration was sufficiently low or group D (dioestrus) (n = 26) if blood P4 concentration was sufficiently high. All animals in the second half of pregnancy were classified into group P (n = 33). Acepromazine (0.05 mg kg(-1) ) was administered intramuscularly as preanaesthetic medication, and sodium thiopental (10 mg kg(-1) , with additional doses if needed) was administered intravenously (IV) for induction of anaesthesia. After endotracheal intubation, halothane (1.1-1.3% end-tidal concentration) in oxygen was used for maintenance of anaesthesia. Lower oesophageal pH was monitored continuously throughout surgery using a pH-measuring probe. Reflux was considered to have occurred whenever pH values of >7.5 (alkaline reflux) or reflux) were recorded. On completion of surgery, carprofen (4 mg kg(-1) ) was administered IV. Further administration of analgesics post-operatively was dictated by visual analogue scale pain scoring. Acid GOR was observed in five of 26 dogs in group D, six of 35 group A, and 12 of 33 group P (p = 0.152). The incidence of GOR in group P approached statistical significance and was higher than the incidence in the combined group A + D (one sided p = 0.044, two sided p = 0.077). In dogs undergoing ovariohysterectomy, GOR during anaesthesia occurs with a high incidence in dogs in the second half of pregnancy compared to non-pregnant animals during anoestrus or dioestrus. Measures could be taken in such cases

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.

AIM: To examine the efficiency of oesophageal flap valvuloplasty and wrapping suturing technique in decreasing the rate of postoperative gastrooesophageal reflux disease in a dog model. METHODS: We operated on 10 dogs in this study. First, we resected a 5-cm portion of the distal oesophagus and then restored the continuity of the oesophageal and gastric walls by end-to-end anastomosis. A group of five dogs was subjected to the oesophageal flap valvuloplasty and wrapping suturing technique, whereas another group (control) of five dogs was subjected to the stapling technique after oesophagectomy. The symptom of gastrooesophageal reflux was recorded by 24-h pH oesophageal monitoring. Endoscopy and barium swallow examination were performed on all dogs. Anastomotic leakage was observed by X-ray imaging, whereas benign anastomotic stricture and mucosal damage were observed by endoscopy. RESULTS: None of the 10 dogs experienced anastomotic leakage after oesophagectomy. Four dogs in the new technology group resumed regular feeding, whereas only two of the dogs in the control group tolerated solid food intake. pH monitoring demonstrated that 25% of the dogs in the experimental group exhibited reflux and that none had mucosal damage consistent with reflux. Conversely, both reflux and mucosal damage were observed in all dogs in the control group. CONCLUSION: The oesophageal flap valvuloplasty and wrapping suturing technique can improve the postoperative quality of life through the long-term elimination of reflux oesophagitis and decreased stricture formation after primary oesophageal anastomosis.

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 reflux groups. The correlation between IL-6 and MUC-3 was significant within the control and erosive reflux groups, and the correlation between MUC-1 and MUC-5AC was significant within the erosive reflux group. The results of this study suggest that the profile of mucin expression in the esophageal mucosa is influenced by the pH and composition of the gastro-esophageal reflux. Further work should explore the

Gastro-oesophageal reflux disease (GERD) is characterised by symptomatic heartburn and regurgitation. Treatment with proton pump inhibitors (PPI) effectively decreases heartburn symptoms, but their effects on symptomatic regurgitation are less clear. To determine the impact of PPI therapy on heartburn and regurgitation severity in patients with either non-erosive GERD (NERD) or erosive oesophagitis (EE). Endoscopically-confirmed NERD patients received dexlansoprazole 30 or 60 mg or placebo in a randomised, blinded, 4-week study. Endoscopically-confirmed EE patients received dexlansoprazole 60 mg or lansoprazole 30 mg in two 8-week, randomised, blinded healing studies. The Patient Assessment of Upper Gastrointestinal Symptom Severity questionnaire, which includes a heartburn/regurgitation subscale, was administered to assess symptom severity at baseline, and at weeks 2 and 4 of the NERD study and at weeks 4 and 8 during the EE trials. We defined separate subscales for heartburn and regurgitation for this post-hoc analysis. Among patients with both symptoms at baseline, improvements in individual heartburn and regurgitation subscales along with the original combined heartburn/regurgitation subscale were determined. In the NERD and EE studies, 661 and 1909 patients, respectively, had both heartburn and regurgitation at baseline. NERD patients receiving dexlansoprazole 30 and 60 mg experienced significantly greater improvements in symptom severity for both heartburn and regurgitation compared with placebo. EE patients receiving dexlansoprazole 60 mg had significantly greater improvements in heartburn/regurgitation and heartburn-only subscales at week 4 compared with those receiving lansoprazole. Dexlansoprazole appears to be effective in improving both heartburn and regurgitation, and this improvement is maintained for the duration of treatment. © 2013 John Wiley & Sons Ltd.

Update on the epidemiology of gastro-oesophageal reflux disease: a systematic review

2014-01-01

Objective To update the findings of the 2005 systematic review of population-based studies assessing the epidemiology of gastro-oesophageal reflux disease (GERD). Design PubMed and Embase were screened for new references using the original search strings. Studies were required to be population-based, to include ≥200 individuals, to have response rates ≥50% and recall periods <12 months. GERD was defined as heartburn and/or regurgitation on at least 1 day a week, or according to the Montreal definition, or diagnosed by a clinician. Temporal and geographic trends in disease prevalence were examined using a Poisson regression model. Results 16 studies of GERD epidemiology published since the original review were found to be suitable for inclusion (15 reporting prevalence and one reporting incidence), and were added to the 13 prevalence and two incidence studies found previously. The range of GERD prevalence estimates was 18.1%–27.8% in North America, 8.8%–25.9% in Europe, 2.5%–7.8% in East Asia, 8.7%–33.1% in the Middle East, 11.6% in Australia and 23.0% in South America. Incidence per 1000 person-years was approximately 5 in the overall UK and US populations, and 0.84 in paediatric patients aged 1– 17 years in the UK. Evidence suggests an increase in GERD prevalence since 1995 (p<0.0001), particularly in North America and East Asia. Conclusions GERD is prevalent worldwide, and disease burden may be increasing. Prevalence estimates show considerable geographic variation, but only East Asia shows estimates consistently lower than 10%. PMID:23853213

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.

In 2004, wide variation in the investigation and management of gastro-oesophageal reflux (GOR) of infants on UK major neonatal units was demonstrated. Our aim was to resurvey neonatal practitioners to determine current practice and whether it was now evidence based. A questionnaire was sent to all 207 UK neonatal units. Responses were obtained from 84% of units. The most frequent 'investigation' was a trial of therapy (83% of units); pH studies were used in 38%, upper GI contrast studies in 19% and multichannel intraluminal impedance (MII)/pH studies in 5%. Only six units suggested a threshold for an abnormal pH study and two units for an abnormal MII study. Infants were commenced on antireflux medication without investigation always in 32% of units, often in 29%, occasionally in 19% and only never in 1%. Gaviscon was used as first line treatment in 60% of units, and other medications included ranitidine in 53%, thickening agents in 27%, proton pump inhibitors in 23%, domperidone in 22% and erythromycin in 6%. There remains a wide variation in diagnostic and treatment strategies for infants with suspected GOR on neonatal intensive care units, emphasising the need for randomised trials to determine appropriate GOR management. ©2017 Foundation Acta Paediatrica.

Laparoscopic 180° anterior fundoplication has been shown to achieve similar reflux control to Nissen fundoplication, with fewer side-effects, up to 5 years. However, there is a paucity of long-term follow-up data on this technique and antireflux surgery in general. This study reports 12-year outcomes of a double-blind RCT comparing laparoscopic Nissen versus 180° laparoscopic anterior fundoplication for gastro-oesophageal reflux disease (GORD). Patients with proven GORD were randomized to laparoscopic Nissen or 180° anterior fundoplication. The 12-year outcome measures included reflux control, dysphagia, gas-related symptoms and patient satisfaction. Measures included scores on a visual analogue scale, a validated Dakkak score for dysphagia and Visick scores. Of the initial 163 patients randomized (Nissen 84, anterior 79), 90 (55·2 per cent) completed 12-year follow-up (Nissen 52, anterior 38). There were no differences in heartburn, dysphagia, gas-related symptoms, patient satisfaction or surgical reintervention rate. Use of acid-suppressing drugs was less common after Nissen than after 180° anterior fundoplication: four of 52 (8 per cent) and 11 of 38 (29 per cent) respectively (P = 0·008). The proportion of patients with absent or only mild symptoms was slightly higher after Nissen fundoplication: 45 of 50 (90 per cent) versus 28 of 38 (74 per cent) (P = 0·044). The two surgical procedures provided similar control of heartburn and post-fundoplication symptoms, with similar patient satisfaction and reoperation rates on long-term follow-up. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

Gastro-Esophageal Reflux in Children

Full Text Available 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.

Gastro-oesophageal reflux disease is generally considered to be one of the commonest causes of chronic cough, however randomised controlled trials of proton pump inhibitors have often failed to support this notion. This article reviews the most recent studies investigating the mechanisms thought to link reflux and cough, namely laryngo-pharyngeal reflux, micro-aspiration and neuronal cross-organ sensitisation. How recent evidence might shed light on the failure of acid suppressing therapies and suggest new approaches to treating reflux related cough are also discussed. PMID:23590893

Guidelines recommend that patients with gastro-oesophageal reflux disease are adequately treated with acid-suppressive therapy before undergoing anti-reflux surgery. Little is known of the use of acid-suppressive drugs before anti-reflux surgery. To determine the use of proton pump inhibitors and H2 -receptor antagonists in the year before anti-reflux surgery. A nationwide retrospective study of all patients aged ≥18 undergoing first-time anti-reflux surgery in Denmark during 2000-2012 using data from three different sources: the Danish National Register of Patients, the Danish National Prescription Register, and the Danish Person Register. The study population thus included 2922 patients (median age: 48 years, 55.7% male). The annual proportion of patients redeeming ≥180 DDD of acid-suppressive therapy increased from 17.0% 5 years before anti-reflux surgery to 64.9% 1 year before.

Full Text Available Abstract Background In a cross-sectional community based study, as part of a randomised controlled trial of eradication of Helicobacter pylori infection, the association between blood pressure and symptoms of gastro-oesophageal reflux was examined. Methods Linear regression was used to examine the association between systolic and diastolic blood pressure and the frequency of heartburn and acid regurgitation in 4,902 of 10,537 participants aged 20–59 years. Results In multivariable analyses, adjusted mean systolic blood pressure was 4.2 (95% confidence interval 1.5 to 7.0 mm Hg lower in participants with daily acid regurgitation compared to those with less frequent symptoms. Similarly, for diastolic blood pressure, a reduction of 2.1 (0.0 to 4.3 mm Hg wasobserved. Conclusion People who experience daily symptoms of gastro-oesophageal reflux have lower blood pressure than people with less frequent or no symptoms. It is possible that factors influencing nitric oxide concentrations both at the lower oesophageal sphincter and within the vasculature may be involved. This hypothesis requires confirmation.

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.

Gastro-oesophageal reflux disease (GORD) is a common condition with 3% to 33% of people from different parts of the world suffering from GORD. There is considerable uncertainty about whether people with GORD should receive an operation or medical treatment for controlling the condition. To assess the benefits and harms of laparoscopic fundoplication versus medical treatment for people with gastro-oesophageal reflux disease. We searched the Cochrane Upper Gastrointestinal and Pancreatic Diseases Group (UGPD) Trials Register (June 2015), Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library Issue 6, 2015), Ovid MEDLINE (1966 to June 2015), and EMBASE (1980 to June 2015) to identify randomised controlled trials. We also searched the references of included trials to identify further trials. We considered only randomised controlled trials (RCT) comparing laparoscopic fundoplication with medical treatment in people with GORD irrespective of language, blinding, or publication status for inclusion in the review. Two review authors independently identified trials and independently extracted data. We calculated the risk ratio (RR) or standardised mean difference (SMD) with 95% confidence intervals (CI) using both fixed-effect and random-effects models with RevMan 5 based on available case analysis. Four studies met the inclusion criteria for the review, and provided information on one or more outcomes for the review. A total of 1160 participants in the four RCTs were either randomly assigned to laparoscopic fundoplication (589 participants) or medical treatment with proton pump inhibitors (571 participants). All the trials included participants who had had reflux symptoms for at least six months and had received long-term acid suppressive therapy. All the trials included only participants who could undergo surgery if randomised to the surgery arm. All of the trials were at high risk of bias. The overall quality of evidence was low or very low. None

Objectives To determine the long term clinical effectiveness of laparoscopic fundoplication as an alternative to drug treatment for chronic gastro-oesophageal reflux disease (GORD). Design Five year follow-up of multicentre, pragmatic randomised trial (with parallel non-randomised preference groups). Setting Initial recruitment in 21 UK hospitals. Participants Responders to annual questionnaires among 810 original participants. At entry, all had had GORD for >12 months. Intervention The surgeon chose the type of fundoplication. Medical therapy was reviewed and optimised by a specialist. Subsequent management was at the discretion of the clinician responsible for care, usually in primary care. Main outcome measures Primary outcome measure was self reported quality of life score on disease-specific REFLUX questionnaire. Other measures were health status (with SF-36 and EuroQol EQ-5D questionnaires), use of antireflux medication, and complications. Results By five years, 63% (112/178) of patients randomised to surgery and 13% (24/179) of those randomised to medical management had received a fundoplication (plus 85% (222/261) and 3% (6/192) of those who expressed a preference for surgery and for medical management). Among responders at 5 years, 44% (56/127) of those randomised to surgery were taking antireflux medication versus 82% (98/119) of those randomised to medical management. Differences in the REFLUX score significantly favoured the randomised surgery group (mean difference 8.5 (95% CI 3.9 to 13.1), Preflux-related operations—most often revision of the wrap. Long term rates of dysphagia, flatulence, and inability to vomit were similar in the two randomised groups. Conclusions After five years, laparoscopic fundoplication continued to provide better relief of GORD symptoms than medical management. Adverse effects of surgery were uncommon and generally observed soon after surgery. A small proportion had re-operations. There was no evidence of long term adverse

110 patients with suspected oesophageal symptoms were investigated by means of oesophageal endoscopy (OE), 24-h pH- metry, and oesophageal scintigraphy (ES). When 24-h pH-metry formed the basis for diagnosis of gastrooesophageal reflux disease (GERD), the sensitivity for ES at abdominal compression was 64%, but no statistically significant differences were found among erect refluxers, supine refluxers, and comibined refluxers. Only 4% of the GERD patients had pathologic oesophageal clearing at ES. The more severe the macroscopic oesophagitis found by OE, the more pronounced were the abnormal findings at 24-h pH-metry and at ES with abdominal compression. Increased postprandial reflux was associated with gastro-oesophageal reflux and hiatal hernia at ES with abdominal compression and the most severe form of oesophagitis, respectively. It is concluded that ES has too low sensitivity to be recommended as a screening test for GERD. Nevertheless, the specificity of 76% can to some extent help us to rule out GERD in patients. 19 refs., 7 tabs.

Novel therapeutics for gastro-esophageal reflux symptoms.

Science.gov (United States)

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.

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.

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

Science.gov (United States)

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.

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.

Helicobacter pylori eradication and reflux disease onset: did gastric acid get "crazy"?

Science.gov (United States)

Zullo, Angelo; Hassan, Cesare; Repici, Alessandro; Bruzzese, Vincenzo

2013-02-14

Gastroesophageal reflux disease (GORD) is highly prevalent in the general population. In the last decade, a potential relationship between Helicobacter pylori (H. pylori) eradication and GORD onset has been claimed. The main putative mechanism is the gastric acid hypersecretion that develops after bacterial cure in those patients with corpus-predominant gastritis. We performed a critical reappraisal of the intricate pathogenesis and clinical data available in this field. Oesophagitis onset after H. pylori eradication in duodenal ulcer patients has been ascribed to a gastric acid hypersecretion, which could develop following body gastritis healing. However, the absence of an acid hypersecretive status in these patients is documented by both pathophysiology and clinical studies. Indeed, duodenal ulcer recurrence is virtually abolished following H. pylori eradication. In addition, intra-oesophageal pH recording studies failed to demonstrated increased acid reflux following bacterial eradication. Moreover, oesophageal manometric studies suggest that H. pylori eradication would reduce--rather than favor--acid reflux into the oesophagus. Finally, data of clinical studies would suggest that H. pylori eradication is not significantly associated with either reflux symptoms or erosive oesophagitis onset, some data suggesting also an advantage in curing the infection when oesophagitis is already present. Therefore, the legend of "crazy acid" remains--as all the others--a fascinating, but imaginary tale.

To report the prevalence of abnormal fluoroscopic findings in brachycephalic dogs that were presented to a referral hospital for obstructive airway syndrome. Hospital records between May 2013 and November 2015 identified 36 brachycephalic dogs investigated for obstructive airway disease: 21 French bulldogs, six bulldogs, four Boston terriers, two pugs, two boxers and one shih-tzu. The presence or absence of hiatal hernia, delayed oesophageal transit, gastro-oesophageal reflux and redundant oesophagus were recorded. Of the 36 dogs, 16 had hiatal hernia, all of which were French bulldogs; 31 dogs had delayed oesophageal transit time, 27 had gastro-oesophageal reflux, and four had redundant oesophagus. Clinical Significance: The prevalence of hiatal hernia is higher than expected in the French bulldog, and there was a high prevalence of oesophageal disease in this group in general. These results suggest a need to investigate similar cases for evidence of gastrointestinal disease that may also require attention. © 2017 British Small Animal Veterinary Association.

Gastro-oesophageal reflux (GOR) is common in infants. When the condition causes pathological symptoms and/or complications it is considered gastro-oesophageal reflux disease (GORD). It appears to be increasingly diagnosed and causes great distress in the first year of infancy. In New South Wales (NSW), residential parenting services support families with early parenting difficulties. These services report a large number of babies admitted with a label of GOR/GORD. The aim of this study was to explore the maternal and infant characteristics, obstetric interventions, and reasons for clinical reporting of GOR/GORD in NSW in the first 12 months following birth (2000-2011). A three phase, mixed method sequential design was used. Phase 1 included a linked data population based study (n = 869,188 admitted babies). Phase 2 included a random audit of 326 medical records from admissions to residential parenting centres in NSW (2013). Phase 3 included eight focus groups undertaken with 45 nurses and doctors working in residential parenting centres in NSW. There were a total of 1,156,020 admissions recorded of babies in the first year following birth, with 11,513 containing a diagnostic code for GOR/GORD (1% of infants admitted to hospitals in the first 12 months following birth). Babies with GOR/GORD were also more likely to be admitted with other disorders such as feeding difficulties, sleep problems, and excessive crying. The mothers of babies admitted with a diagnostic code of GOR/GORD were more likely to be primiparous, Australian born, give birth in a private hospital and have: a psychiatric condition; a preterm or early term infant (37-or-38 weeks); a caesarean section; an admission of the baby to SCN/NICU; and a male infant. Thirty six percent of infants admitted to residential parenting centres in NSW had been given a diagnosis of GOR/GORD. Focus group data revealed two themes: "It is over diagnosed" and "A medical label is a quick fix, but what else could be

Autosomal dominant hereditary sensory neuropathy (HSN I) is a clinically and genetically heterogeneous group of disorders, and in some families it is due to mutations in the serine palmitoyltransferase (SPTLC1) gene. We have characterized two families with HSN I associated with cough and gastro-oesophageal reflux (GOR). From a large Australian family, 27 individuals and from a smaller family, 11 individuals provided clinical information and blood for genetic analysis. Affected individuals had an adult onset of paroxysmal cough, GOR and distal sensory loss. Cough could be triggered by noxious odours or by pressure in the external auditory canal (Arnold's ear-cough reflex). Other features included throat clearing, hoarse voice, cough syncope and sensorineural hearing loss. Neurophysiological and pathological studies demonstrated a sensory axonal neuropathy. Gastric emptying studies were normal, and autonomic function and sweat tests were either normal or showed distal hypohidrosis. Cough was likely to be due to a combination of denervation hypersensitivity of the upper airways and oesophagus, and prominent GOR. Most affected individuals were shown on 24 h ambulatory oesophageal pH monitoring to have multiple episodes of GOR, closely temporally associated with coughing. Hoarse voice was probably attributable to acid-induced laryngeal damage, and there was no evidence of vocal cord palsy. No other cause for cough was found on most respiratory or otorhinological studies. Linkage to chromosome 3p22-p24 has been found in both families, with no evidence of linkage to loci for known HSN I, autosomal dominant hereditary motor and sensory neuropathy, hereditary GOR or triple A syndrome. These families represent a genetically novel variant of HSN I, with a distinctive cough owing to involvement of the upper aerodigestive tract.

A gastro-oesophageal intussusception in a female, six-week-old German shepherd dog was treated surgically with success. The dog was presented with acute dyspnoea and signs of shock. After laparotomy, the herniated organs were reduced from the lumen of the oesophagus into the abdomen and an imbrication of the oesophageal hiatus, an appositional fundoplication and a left-sided incisional fundopexy were performed. The dog made an uneventful recovery. Eighteen months after surgery the dog is still alive, with no clinical signs despite the persistent presence of megaoesophagus

50 children with a strong clinical suspicion of gastroesophageal reflux and 10 control patients were evaluated with gastroesophageal scintiscans. 500 μCi a 1 mCi of Tc sulfur colloid mixed the patients' routine milk or formula feeding was administred and serial images of the abdomen and thorax were obtained. A positive scintiscan was found in 35 patients (sensitivity 70%) and none of the controls (specificity 100%). A comparison of findings in 34 patients refered for both radiographic and radionucleide studies showed that barium studies were positive in 38% and radionucleide in 64.7%. We found this examination to be more sensitive that the standard barium radiography particularly in patients with respiratory symptoms. We concluded that the GE scintiscan is complementary to barium studies in the diagnosis of GE reflux. Pulmonary aspiration of gastric contents was detected in only a case of the 35 patients with documented GE reflux. A T1/2 emptying gastric longer than 90 minutes (linear calculation) or 105 minutes (exponential calculation) is an indirect GE reflux test. This procedure is simple, safe more physiologic than other available examinations

Available evidence showed inconsistent results between laparoscopic Nissen's fundoplication (LNF) and open Nissen's fundoplication (ONF) for children with gastro-oesophageal reflux disease (GERD), so this study aimed to evaluate the efficacy and safety between LNF and ONF. Systematic, comprehensive literature searches were conducted to include randomized controlled trials (RCTs) that compared LNF and ONF for GERD. Two reviewers independently selected studies, abstracted data and assessed the methodological quality and evidence level. Data was analyzed by Review Manager Version 5.0. Risk ratio (RR) was used for dichotomous outcomes, and mean difference (MD) was used for continuous scales. Heterogeneity was estimated with the I 2 statistic, fixed-effect model was used if I 2 <50%, and otherwise random-effects model was used. Three RCTs (171 children) were included. There was not a statistical difference in mortality (RR 1.12, 95%CI 0.50 2.48), or postoperative complications (RR 0.87, 95%CI 0.61 1.25), readmission (RR 1.53, 95%CI 0.67 3.51), or hospital stay (MD 0.85, 95%CI -0.06 1.75) between LNF and ONF. But LNF was associated with more incidence of recurrence (RR 3.32, 95%CI 1.40 7.84), longer surgery duration (MD 76.33, 95%CI 69.37 83.28), but fewer retching (RR 0.11, 95%CI 0.02 0.58) than ONF. LNF might be as effective and safe as ONF in the short and long term, but both were associated with high risk of recurrence and mortality, especially for those children with neurological impairment, before the age of 18 months and female gender. This required a comprehensive evaluation of children before surgery. Copyright © 2016 IJS Publishing Group Ltd. Published by Elsevier Ltd. All rights reserved.

Results of a radioisotope method of the gastro-esophageal reflux are presented in patients with achalasia cardiae after different types of surgical treatment. Both Belsey-Mark and modified Nissen techniques are effective in preventing spontaneous gastroesophageal reflux, however 2 patients after Nissen fundoplication demonstrated gastro-esophageal reflux provoked by abdominal compression. This simple, noninvasive and physiologic method is an appropriate diagnostic tool for evaluating the efficiency of different anti reflux surgical techniques and is recommended for follow-up studies of patients after gastro-esophageal surgical intervention.

2001-01-01

BACKGROUND—Patients with gastro-oesophageal reflux disease (GORD) frequently report that meals high in fat worsen heartburn. Nevertheless, studies to determine whether high fat meals promote gastro-oesophageal reflux have produced conflicting and equivocal conclusions.
PATIENTS AND METHODS—To determine, alternatively, whether fat in the small intestinal lumen intensifies the perception of heartburn, we studied 11 patients with typical heartburn from GORD. After being placed on omeprazole to suppress endogenous acid, these fasting subjects underwent oesophageal perfusions with graded doses of HCl at pH values of 1.0, 1.5, 2.0, and 2.5. Oesophageal perfusions were conducted while the duodenum was perfused with saline (control) and again with fat at 8 g/h.
RESULTS—Time to onset, intensity, and severity of heartburn varied with dose of oesophageal acid (pheartburn significantly (pheartburn.

A positive scintiscan was found in 35 patients (sensitivity 70%) and none of the controls (specificity 100%). A comparison of findings in 34 patients refered for both radiographic and radionucleide studies showed that barium studies were positive in 38% and radionucleide in 64.7%. We found this examination to be more sensitive that the standard barium radiography particularly in patients with respiratory symptoms. We concluded that the GE scintiscan is complementary to barium studies in the diagnosis of GE reflux. Pulmonary aspiration of gastric contents was detected in only a case of the 35 patients with documented GE reflux. A T1/2 emptying gastric longer than 90 minutes (linear calculation) or 105 minutes (exponential calculation) is an indirect GE reflux test. This procedure is simple, safe more physiologic than other available examinations.

Twice-daily dosing of proton pump inhibitor (PPI), the standard therapy for gastro-oesophageal reflux disease (GERD), is an effective therapy for GERD in SSc. The aim of this study was to compare the efficacy of omeprazole in combination with domperidone vs in combination with algycon in reducing the severity and frequency of reflux symptoms of PPI partial response (PPI-PR) GERD in SSc. Adult SSc patients having PPI-PR GERD were randomly assigned to receive domperidone plus algycon placebo or algycon plus domperidone placebo in a 1:1 ratio plus omeprazole for 4 weeks. The assessment included severity of symptom grading by visual analogue scale, frequency of symptoms by frequency scale for symptoms of GERD and quality of life (QoL) by EuroQol five-dimensions questionnaire scoring. One hundred and forty-eight SSc-GERD patients were enrolled, of whom 88 had PPI-PR. Eighty cases were randomized for either domperidone (n = 38) or algycon (n = 37) therapy. The majority in both groups had the diffuse SSc subset. At the end of the study, no significant difference in symptom grading was found between groups. After treatment and compared with baseline, the severity of symptoms, frequency scale for symptoms of GERD and QoL significantly improved in both groups. Five (13.2%) and 8 (21.6%) respective cases in the domperidone and algycon groups did not respond. The prevalence of PPI-PR GERD is common. Domperidone and algycon are equally effective treatments in combination with omeprazole. However, ∼17% of patients were non-responsive, so the effectiveness of domperidone, algycon and PPI combination therapy should be further investigated. https://clinicaltrials.gov (NCT01878526). © The Author 2016.

Full Text Available Congenital trcheo-oesophageal fistula (TOF without oesophageal atresia is usually diagnosed and managed in the neonatal period. Its presentation in adulthood is a rarity. Traditional treatment of a TOF in adults involves its repair via a thoracotomy. We report the case of a 23-year-old man diagnosed with an H-type TOF during workup undertaken for his symptoms of gastro-oesophageal reflux. This fistula located at the level of third thoracic vertebra was repaired successfully using a thoracoscopic approach.

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

Drug histories were obtained from 76 patients at the time of initial Eder-Puestow dilatation for benign oesophageal stricture. Six patients had consumed drugs known to cause oesophageal ulceration (emepronium bromide and potassium preparations). Of the remaining 70 patients, 22 had regularly taken a non-steroidal anti-inflammatory drug before the onset of dysphagia compared with 10 patients in a control group matched for age and sex; this difference was significant (p less than 0.02). Non-steroidal anti-inflammatory drugs may have a causative role in the formation of oesophageal stricture in patients with gastro-oesophageal reflux, in whom they should be prescribed with caution.

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.

Thioredoxin interacting protein and its association with clinical outcome in gastro-oesophageal adenocarcinoma

Full Text Available The overall prognosis for operable gastro-oesophageal adenocarcinoma remains poor and therefore neoadjuvant chemotherapy has become the standard of care, in addition to radical surgery. Certain anticancer agents (e.g. anthracyclines and cisplatin generate damaging reactive oxygen species as by-products of their mechanism of action. Drug effectiveness can therefore depend upon the presence of cellular redox buffering systems that are often deregulated in cancer. The expression of the redox protein, thioredoxin interacting protein, was assessed in gastro-oesophageal adenocarcinomas. Thioredoxin interacting protein expression was assessed using conventional immunohistochemistry on a tissue microarray of 140 adenocarcinoma patients treated by primary surgery alone and 88 operable cases treated with neoadjuvant chemotherapy. In the primary surgery cases, high thioredoxin interacting protein expression associated with a lack of lymph node involvement (p=0.005, no perineural invasion (p=0.030 and well/moderate tumour differentiation (p=0.033. In the neoadjuvant tumours, high thioredoxin interacting protein expression was an independent marker for improved disease specific survival (p=0.002 especially in cases with anthracycline-based regimes (p=0.008. This study highlights the potential of thioredoxin interacting protein as a biomarker for response in neoadjuvant treated gastro-oesophageal adenocarcinoma and may represent a useful therapeutic target due to its association with tumour progression.

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.

Ability to predict freedom from heartburn relapse during maintenance therapy for healed reflux oesophagitis may facilitate optimal treatment choices for individual patients. To determine factors predicting freedom from heartburn relapse during maintenance proton pump inhibitor therapy in patients with healed reflux oesophagitis. This post-hoc analysis used data from the maintenance phase of the EXPO study (AstraZeneca study code: SH-NEG-0008); 2766 patients with healed reflux oesophagitis and resolved heartburn received once-daily esomeprazole 20 mg or pantoprazole 20 mg for 6 months. Multiple logistic regression analysis determined factors associated with freedom from heartburn relapse. Heartburn relapse rates were lower with esomeprazole than pantoprazole in all subgroups analysed. Esomeprazole treatment was the factor most strongly associated with freedom from heartburn relapse (odds ratio 2.08; P heartburn relapse were Helicobacter pylori infection, greater age, non-obesity, absence of epigastric pain at baseline, pre-treatment nonsevere heartburn and GERD symptom duration heartburn relapse during maintenance proton pump inhibitor therapy for healed reflux oesophagitis, the strongest being choice of proton pump inhibitor. These findings outline the importance of optimizing acid control and identifying predictors of relapse for effective long-term symptom management in reflux oesophagitis patients.

Gastro-oesophageal reflux disease (GORD) and dental erosions (DE) have an established association. We assessed whether GORD is associated with DE controlling for acidified food intake and their relationships with quality of life (QOL). In this cross-sectional study, 419 adult patients who sought dentistry consultation were considered eligible. Patients responded to questionnaires for GORD symptoms, acidified food ingestion and World Health Organization quality of life (WHOQOL Bref), followed by an oral examination, in which DE were characterized according to the Smith & Knight criteria. A total of 417 patients were included (43.8±13.7 years; 68.8% women). There were 143 patients with GORD (34.3%) and 274 controls without GORD. The prevalence of DE was higher in GORD patients compared with the controls (25.9 vs. 17.2%; P=0.041). GORD was associated with DE after adjusting for acidified food intake (P=0.035), with a prevalence ratio of 1.52 (0.95 confidence interval 1.03-2.22). The WHOQOL Bref score was significantly lower in the presence of GORD [median 17.2 (GORD-DE-) vs. 15.4 (GORD+DE+); P<0.01], irrespective of DE. In adults examined in a referential dentistry centre in South America, DE were prevalent and significantly associated with GORD. This association was independent of the intake of acidified food in our study. Impairment in QOL was observed in GORD patients irrespective of the presence of DE.

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. 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. 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. 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.

During a reflux event the oesophagus is exposed to a heterogeneous mixture of gastric juice components. The role of non-acid components of the refluxate in causing damage to the oesophagus is now well established but no therapeutic option exists to address this. The role of Gaviscon Advance (GA), a raft-forming alginate suspension, in protecting the oesophagus from damage by pepsin and bile acids (aggressors) was investigated using a series of in-vitro models. GA was able to dose-dependently inhibit pepsin activity over and above the neutralisation effect of the formulation. This was evident against both protein and collagen substrates using two distinct colorimetric assays. GA was able to retard the diffusion of pepsin and multiple bile acids using a Franz cell model. Using the raft-forming mode of action GA was able to remove both pepsin and multiple bile acids from a simulated reflux event. There was capacity in the GA raft to accommodate aggressors from multiple reflux events. GA can specifically remove both pepsin and bile acids from the refluxate, limit their diffusion and affect enzymatic activity of pepsin. There is a role for GA to reduce the damaging potential of the refluxate and thus protect the oesophagus.

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.

Exercise and the Prevention of Oesophageal Cancer (EPOC study protocol: a randomized controlled trial of exercise versus stretching in males with Barrett's oesophagus

Full Text Available Abstract Background Chronic gastro-oesophageal reflux disease and excessive body fat are considered principal causes of Barrett's oesophagus (a metaplastic change in the cells lining the oesophagus and its neoplastic progression, oesophageal adenocarcinoma. Metabolic disturbances including altered levels of obesity-related cytokines, chronic inflammation and insulin resistance have also been associated with oesophageal cancer development, especially in males. Physical activity may have the potential to abrogate metabolic disturbances in males with Barrett's oesophagus and elicit beneficial reductions in body fat and gastro-oesophageal reflux symptoms. Thus, exercise may be an effective intervention in reducing oesophageal adenocarcinoma risk. However, to date this hypothesis remains untested. The 'Exercise and the Prevention of Oesophageal Cancer Study' will determine whether 24 weeks of exercise training will lead to alterations in risk factors or biomarkers for oesophageal adenocarcinoma in males with Barrett's oesophagus. Our primary outcomes are serum concentrations of leptin, adiponectin, tumour necrosis factor-alpha, C-reactive protein and interleukin-6 as well as insulin resistance. Body composition, gastro-oesophageal reflux disease symptoms, cardiovascular fitness and muscular strength will also be assessed as secondary outcomes. Methods/Design A randomized controlled trial of 80 overweight or obese, inactive males with Barrett's oesophagus will be conducted in Brisbane, Australia. Participants will be randomized to an intervention arm (60 minutes of moderate-intensity aerobic and resistance training, five days per week or a control arm (45 minutes of stretching, five days per week for 24 weeks. Primary and secondary endpoints will be measured at baseline (week 0, midpoint (week 12 and at the end of the intervention (week 24.

1989-03-01

The oesophageal transit time of half a marshmallow was measured radiologically in 17 controls, 28 patients with gastro-oesophageal reflux pre-operatively, 36 patients soon after implantation of the Angelchik prosthesis (2-9 weeks) and in 23 patients later postoperatively (9-48 months). Sixteen postoperative patients also underwent oesophageal manometry. All control and pre-operative patients had a marshmallow transit time of less than 1 min; 67 per cent of the early postoperative patients had prolonged transit and 70 per cent of the late tests were similarly abnormal. Prolonged oesophageal transit as measured by marshmallow swallow correlated well with symptoms of solid food dysphagia. Most, but not all, patients with an abnormal marshmallow swallow had abnormal manometric findings. The oesophageal transit of solid food is significantly slowed after the Angelchik procedure and this is not a transient postoperative phenomenon.

2014-03-01

Recent interest has focused on the role of perioperative epidural analgesia in improving cancer outcomes. The heterogeneity of studies (tumour type, stage and outcome endpoints) has produced inconsistent results. Clinical practice also highlights the variability in epidural effectiveness. We considered the novel hypothesis that effective epidural analgesia improves cancer outcomes following gastro-oesophageal cancer surgery in patients with grouped pathological staging. Following institutional approval, a database analysis identified 140 patients, with 2-year minimum follow-up after gastro-oesophageal cancer surgery. All patients were operated on by a single surgeon (2005-2010). Information pertaining to cancer and survival outcomes was extracted. Univariate analysis demonstrated a 1-year 14% vs. 33% (P = 0.01) and 2-year 27% vs. 40% [hazard ratio (HR)=0.59; 95% CI, 0.32-1.09, P = 0.087] incidence of cancer recurrence in patients with (vs. without) effective (> 36 h duration) epidural analgesia, respectively. Multivariate analysis demonstrated increased time to cancer recurrence (HR = 0.33; 95% CI: 0.17-0.63, P benefit (HR = 0.42; 95% CI: 0.21-0.83, P benefit in patients with oesophageal cancer (HR = 0.34; 95% CI: 0.16-0.75, P = 0.005) and in patients with tumour lymphovascular space infiltration (LVSI), (HR = 0.49; 95% CI: 0.26-0.94, P = 0.03). Effective epidural analgesia improved estimated median time to death (2.9 vs. 1.8 years, P = 0.029) in patients with tumour LVSI. This study found an association between effective post-operative epidural analgesia and medium-term benefit on cancer recurrence and survival following oesophageal surgery. A prospective study that controls for disease type, stage and epidural effectiveness is warranted. © 2014 The Acta Anaesthesiologica Scandinavica Foundation. Published by John Wiley & Sons Ltd.

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 (p3000Ohm), CAAG (>2000Ohm) and NERD (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.

Alginates form a raft above the gastric contents, which may suppress gastro-oesophageal reflux; however, inconsistent effects have been reported in mechanistic and clinical studies. To visualise reflux suppression by an alginate-antacid [Gaviscon Advance (GA), Reckitt Benckiser, UK] compared with a nonraft-forming antacid using magnetic resonance imaging (MRI), and to determine the feasibility of pH-impedance monitoring for assessment of reflux suppression by alginates. Two studies were performed: (i) GA and antacid (Alucol, Wander Ltd, Switzerland) were visualised in the stomach after ingestion in 12 healthy volunteers over 30 min after a meal by MRI, with reflux events documented by manometry. (ii) A randomised controlled, double-blind cross-over trial of post-prandial reflux suppression documented by pH-impedance in 20 patients randomised to GA or antacid (Milk of Magnesia; Boots, UK) after two meals taken 24 h apart. MRI visualized a "mass" of GA form at the oesophago-gastric junction (OGJ); simple antacid sank to the distal stomach. The number of post-prandial common cavity reflux events was less with GA than antacid [median 2 (0-5) vs. 5 (1-11); P < 0.035]. Distal reflux events and acid exposure measured by pH-impedance were similar after GA and antacid. There was a trend to reduced proximal reflux events with GA compared with antacid [10.5 (8.9) vs. 13.9 (8.3); P = 0.070]. Gaviscon Advance forms a 'mass' close to the OGJ and significantly suppresses reflux compared with a nonraft-forming antacid. Standard pH-impedance monitoring is suitable for clinical studies of GA in gastro-oesophageal reflux disease patients where proximal reflux is the primary outcome. © 2013 Blackwell Publishing Ltd.

Chronic gastro-oesophageal reflux disease and excessive body fat are considered principal causes of Barrett's oesophagus (a metaplastic change in the cells lining the oesophagus) and its neoplastic progression, oesophageal adenocarcinoma. Metabolic disturbances including altered levels of obesity-related cytokines, chronic inflammation and insulin resistance have also been associated with oesophageal cancer development, especially in males. Physical activity may have the potential to abrogate metabolic disturbances in males with Barrett's oesophagus and elicit beneficial reductions in body fat and gastro-oesophageal reflux symptoms. Thus, exercise may be an effective intervention in reducing oesophageal adenocarcinoma risk. However, to date this hypothesis remains untested. The 'Exercise and the Prevention of Oesophageal Cancer Study' will determine whether 24 weeks of exercise training will lead to alterations in risk factors or biomarkers for oesophageal adenocarcinoma in males with Barrett's oesophagus. Our primary outcomes are serum concentrations of leptin, adiponectin, tumour necrosis factor-alpha, C-reactive protein and interleukin-6 as well as insulin resistance. Body composition, gastro-oesophageal reflux disease symptoms, cardiovascular fitness and muscular strength will also be assessed as secondary outcomes. A randomized controlled trial of 80 overweight or obese, inactive males with Barrett's oesophagus will be conducted in Brisbane, Australia. Participants will be randomized to an intervention arm (60 minutes of moderate-intensity aerobic and resistance training, five days per week) or a control arm (45 minutes of stretching, five days per week) for 24 weeks. Primary and secondary endpoints will be measured at baseline (week 0), midpoint (week 12) and at the end of the intervention (week 24). Due to the increasing incidence and very high mortality associated with oesophageal adenocarcinoma, interventions effective in

Full Text Available Introduction: Both inflammation and mitochondrial DNA (mtDNA mutation are thought to play a role in the many human cancers. The aim of this study was to evaluate the relationship between inflammation and accumulation of mitochondrial DNA (mtDNA mutations in the D-loop region in carcinogenesis of gastro-oesophageal adenocarcinomas. Materials and Methods: Blood samples of 20 patients with gastro-oesophageal adenocarcinoma were taken for measurement of serum C-reactive protein (CRP concentration. Direct sequencing of mtDNA in the D-loop region was done in the 20 adenocarcinoma samples and their corresponding surrounding non-cancerous tissue. Sequences were compared with existing mtDNA databases to identify mutations. Results: mtDNA mutations in the D-loop region occur commonly with almost identical frequency in both non-cancerous tissue (3.0 ΁ 1.6 and adenocarcinoma (3.1 ΁ 1.9 (P = 0.916, paired t-test. CRP levels are not predictive of the number of D-loop mutations in both adenocarcinoma (β: -0.131; 95% CI: -2.354-1.364; P = 0.583 and non-cancerous tissue samples (β: 0.130; 95% CI: -1.125-1.933; P = 0.586. Five new mutations were identified that were not recorded previously in mtDNA databases. Conclusion: D-loop mtDNA mutations are common in both gastro-oesophageal adenocarcinoma and surrounding non-cancerous tissue. However, the accumulation of such mutations appears to occur independent of systemic inflammation. The frequency of D-loop mutations is likely not useful as a marker for carcinogenesis in gastro-oesophageal adenocarcinoma.

To determine the outcome of clinically suspected gastro esophageal reflux in neonates and infants. To find a protocol for evaluation of these patients in order to reduce unnecessary radiation to neonates and infants. Fifty three neonates and infants of up to 1 year of age with clinical suspicion of gastro esophageal reflux (GER) were referred for Upper gastro intestinal barium studies. This retrospective descriptive case study was carried out over a period of one year starting from October, 2006 to September, 2007. Positive cases were followed for another one year to see the final outcome. The neonate and infants of upto one year of age, referred from Neonatal intensive care unit (NICU), Paediatric ward and Out Patient Department (OPD) were included in this study. Out of 53 cases 32 were positive for G.E.R and no reflux could be identified in rest of the patients. Out of these positive cases only 4 had massive or severe G.E.R. These patients were prescribed conservative and medical treatment and were advised to follow up in the O.P.D where on subsequent follow ups the medical treatment was stopped as there were no further complaints .These patients showed normal weight gain on subsequent O.P.D visits. Other positive cases only had mild to moderate G.E.R and they were managed conservatively. These patients showed normal weight gain on subsequent O.P.D visits with complete resolution of symptoms. Regurgitation or gastro esophageal reflux is a common finding in the first 3 months of life (especially in preterm infants) and usually resolves by 6-12 months of age and should not be over investigated.

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.

In order to assess the outlook for patients with peptic oesophageal strictures treated by Eder Puestow dilatation at fibreoptic endoscopy, 50 patients were followed up for periods ranging from nine months to four years. Twenty patients (40%) required only a single dilatation, and the remaining 30 (60%) required multiple dilatations. The frequency of dilatation tended to decrease with time. There was one death attributable to the procedure. Two patients developed an adenocarcinoma at the site of the stricture. We conclude that conservative management of peptic oesophageal stricture combining the use of dilatation at fibreoptic endoscopy with medical measures to control gastro-oesophageal reflux offers a relatively safe means of providing symptomatic relief, maintaining nutrition, and allowing the patient an acceptable quality of life.

Diagnosis of gastro esophageal reflux disease (GERD) in children is challenging. 24-h-pH-multichannel-intraluminal-impedance measurement (pH-MII) is the best diagnostic tool to display gastro esophageal reflux whereas esophageal endoscopy indicates mucosal lesions. The aim of this study was to compare esophageal endoscopy results with reflux parameters such as acid exposure time (reflux index RI), bolus exposure time (bolus index BI), baseline impedance level (BIL) detected by pH-MII in children with suspected GERD. Analysis of data from 285 children (38 infants) referred to our hospital with suspected GERD. Division into three 'reflux esophagitis' (RE)-stages depending on the severity of endoscopic and histological findings and comparison with reflux parameters in these stages. Further categorization into four groups based on the pH-MII-results. Children with high-grade esophagitis had a significantly lower BIL; otherwise there was no significant association between elevated reflux parameters and esophagitis. Pathological pH-MII results (RI and BI) were associated with lower BIL in the distal impedance channel. The BIL was significantly lower in infants compared to children >1 year regardless of the RI or BI. The main difference between these groups regarding reflux parameters was a longer BI and a higher number of retrograde bolus movements. Pathologic pH-MII results are not predictive for an erosive esophagitis and vice versa. Therefore, these two procedures cannot replace each other. A lower BIL is associated with esophagitis ≥ LA-grade B and may be caused by longer acid but also by longer bolus exposure and thus may be another useful parameter in GERD monitoring.

Objective: This study was carried out to evaluate the frequency, types and complications of Barrett's esophagus in symptomatic gastro-esophageal reflux patients. Subjects: A total of 100 patients of gastro-esophageal reflux were studied to evaluate the frequency, types and complications of Barrett's esophagus. Endoscopic biopsies were taken and examined with H and E and various special stains like PAS, Alcian blue/PAS, high iron diamine/ Alcian blue and Giemsa stains. Results: Of 100 cases studied, 32 were found to have Barrett's esophagus on microscopy. The remaining 68 cases showed low and high grade changes of gastro-esophageal reflux. Conclusion: In comparison with studies from western countries, Barrett's esophagus was found to be relatively more common in our population. However, the frequency of complications like ulcer, stricture, dysplasia and adenocarcinoma was lesser. (author)

Chemoradiotherapy in tumours of the oesophagus and gastro-oesophageal junction.

Hulshof, M C C M; van Laarhoven, H W M

2016-08-01

Oesophageal cancer remains a malignancy with a poor prognosis. However, in the recent 10-15 years relevant progress has been made by the introduction of chemoradiotherapy (CRT) for tumours of the oesophagus or gastro-oesophageal junction. The addition of neo-adjuvant CRT to surgery has significantly improved survival and locoregional control, for both adenocarcinoma and squamous cell carcinoma. For irresectable or medically inoperable patients, definitive CRT has changed the treatment intent from palliative to curative. Definitive CRT is a good alternative for radical surgery in responding patients with squamous cell carcinoma and those running a high risk of surgical morbidity and mortality. For patients with an out-of-field solitary locoregional recurrence after primary curative treatment, definitive CRT can lead to long term survival. Copyright © 2016. Published by Elsevier Ltd.

Although obesity rates are higher in African-American than European-American women, gastro-oesophageal reflux disease (GERD) and its comorbidities are more prevalent in European-American women. A common denominator for increased adiposity, and consequent insulin resistance, is excess dietary macronutrient intake - which may promote greater prevalence and severity of GERD in women. To investigate whether GERD is more robustly associated with dietary carbohydrate intake, particularly dietary simple carbohydrate intake, and insulin resistance in European-American women. About 144 obese women were assessed at baseline and 16 weeks after consuming a high-fat/low-carbohydrate diet. GERD diagnosis and medication usage was confirmed in medical records with symptoms and medications assessed weekly. About 33.3% (N = 33) of European-American and 20.0% (N = 9) of African-American women had GERD at baseline. Total carbohydrate (r = 0.34, P < 0.001), sugars (r = 0.30, P = 0.005), glycaemic load (r = 0.34, P = 0.001) and HOMA IR (r = 0.30, P = 0.004) were associated with GERD, but only in European-American women. In response to high-fat/low-carbohydrate diet, reduced intake of sugars was associated with reduced insulin resistance. By the end of diet week 10, all GERD symptoms and medication usage had resolved in all women. GERD symptoms and medication usage was more prevalent in European-American women, for whom the relationships between dietary carbohydrate intake, insulin resistance and GERD were most significant. Nevertheless, high-fat/low-carbohydrate diet benefited all women with regard to reducing GERD symptoms and frequency of medication use. © 2016 John Wiley & Sons Ltd.

Gastro-oesophageal reflux disease (GORD) is a common comorbidity among patients with rheumatoid arthritis (RA). While GORD has been attributed to the antirheumatic medications, no studies of human cohorts have investigated a link between GORD and RA. This study investigates whether GORD is associated with a subsequent RA diagnosis over a 5-year follow-up using a population-based dataset. Taiwan PARTICIPANTS: We used data from the Taiwan Longitudinal Health Insurance Database. The study group consisted of 13 645 patients with an ambulatory claim showing a GORD diagnosis. We used propensity score matching to select 13 645 comparison patients (one per study patient with GORD). We tracked each patient's claims over a 5-year period to identify those who subsequently received a diagnosis of RA. Cox proportional hazard (PH) regression modelling was used for analysis. Over 5-year follow-up, RA incidence rate per 1000 person-years was 2.81 among patients with GORD and 0.84 among the comparison group. Cox PH modelling showed that GORD was independently associated with a 2.84-fold increased risk of RA (95% CI 2.09 to 3.85) over 5-year follow-up, after adjusting for the number of ambulatory care visits within the year following the index date (to mitigate surveillance bias). We observed that GORD might associate with subsequent RA occurrence. Because current treatment guidelines for RA emphasise early diagnosis and prompt treatment, the observed association between GORD and RA may help acquaint clinicians to patients with GORD with higher RA risk and facilitate early diagnosis and treatment. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

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 reflux and also for following children post-treatment.

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.

Full Text Available Eosinophilic esophagitis (EoE and gastro-esophageal reflux disease are among the major causes of isolated esophageal eosinophilia. Isolated esophageal eosinophilia meeting criteria for EoE may respond to proton pump inhibitor (PPI treatment. This entity is termed proton pumps inhibitor responsive esophageal eosinophilia (PPI-REE. Gastro-esophageal reflux is thought to comprise a subgroup of patients with PPI-REE. According to the latest guidelines, PPI responsiveness distinguishes people with PPI-REE from patients having EoE (non-responders. In this report, two unusual cases with findings belonging to both EoE and PPI-REE are discussed with known and unknown facts.

Airway Reflux, Cough and Respiratory Disease

It is increasingly accepted that the effects of gastro-oesophageal reflux are not limited to the gastrointestinal tract. The adjacent respiratory structures are also at risk from material ejected from the proximal oesophagus as a result of the failure of anatomical and physiological barriers. There is evidence of the influence of reflux on several respiratory and otorhinological conditions and although in many cases the precise mechanism has yet to be elucidated, the association alone opens potential novel avenues of therapy to clinicians struggling to treat patients with apparently intractable respiratory complaints. This review provides a description of the airway reflux syndrome, its effects on the lung and current and future therapeutic options. PMID:23251752

Laryngopharyngeal reflux (LPR) and biliary duodenogastric reflux can cause damage to the laryngeal mucosa and voice disorders. The aim of this study was to find out whether levels of pepsin and bile acids in the saliva can serve as diagnostic markers of LPR. A prospective comparative study. Twenty-eight patients with LPR proven via high-resolution manometry and combined multichannel intraluminal impedance and 24-h pH monitoring and 48 healthy controls without symptoms of LPR were included in the study. In the patients with LPR symptoms, oesophagogastroscopy with oesophageal biopsy was performed. The levels of total pepsin, active pepsin, bile acids and the pH of the saliva were determined in all participants and compared between the groups. Reflux symptom index (RSI) and reflux finding score (RFS) were also obtained and compared. The groups differed significantly in RSI (P = 0.00), RFS (P = 0.00), the levels of bile acids (P = 0.005) and total pepsin in saliva (P = 0.023). The levels of total pepsin and bile acids were about three times higher in the patients with LPR than in the healthy controls. There was a significant correlation between the RSI and RFS score and the level of total pepsin and bile acids in the saliva. Histopathological examination of the oesophageal biopsy taken 5 cm above the lower oesophageal sphincter confirmed reflux in almost 93% of patients with symptoms. The study results show that the levels of total pepsin and bile acids in saliva are significantly higher in patients with LPR than in the controls, thus suggesting this as a useful tool in the diagnosis of LPR and particularly biliary LPR. © 2014 John Wiley & Sons Ltd.

Histologic definition of gastro-esophageal reflux disease.

Science.gov (United States)

Chandrasoma, Parakrama T

2013-07-01

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.

Non-specific esophageal dysmotility with impaired clearance is often present in patients with gastro-esophageal reflux disease (GERD), especially those with erosive disease; however the physio-mechanic basis of esophageal dysfunction is not well defined. Retrospective assessment of patients with erosive reflux disease (ERD; n=20) and endoscopy negative reflux disease (ENRD; n=20) with pathologic acid exposure on pH studies (>4.2% time/24 h) and also healthy controls (n=20) studied by high resolution manometry. Esophageal motility in response to liquid and solid bolus swallows and multiple water swallows (MWS) was analyzed. Peristaltic dysfunction was defined as failed peristalsis, spasm, weak or poorly coordinated esophageal contraction (>3cm break in 30 mmHg isocontour). Peristaltic dysfunction was present in 33% of water swallows in controls, 56% ENRD and 76% ERD respectively (Preflux events and increase exposure to gastric refluxate. © 2011 Blackwell Publishing Ltd.

Gastro-esophageal reflux disease (GERD)-related chronic cough (CC) may have multifactorial causes. To clarify the characteristics of esophagopharyngeal reflux (EPR) events in CC patients whose cough was apparently influenced by gastro-esophageal reflux (GER), we studied patients with CC clearly responding to full-dose proton pump inhibitor (PPI) therapy (CC patients). Ten CC patients, 10 GERD patients, and 10 healthy controls underwent 24-h ambulatory pharyngo-esophageal impedance and pH monitoring. Weakly acidic reflux was defined as a decrease of pH by >1 unit with a nadir pH >4. In six CC patients, monitoring was repeated after 8 weeks of PPI therapy. The number of each EPR event and the symptom association probability (SAP) were calculated. Symptoms were evaluated by a validated GERD symptom questionnaire. Weakly acidic gas EPR and swallowing-induced acidic/weakly acidic EPR only occurred in CC patients, and the numbers of such events was significantly higher in the CC group than in the other two groups (P pump inhibitor therapy abolished swallowing-induced acidic/weakly acidic EPR, reduced weakly acidic gas EPR, and improved symptoms (all P gas EPR and swallowing-induced acidic/weakly acidic EPR. A direct effect of acidic mist or liquid refluxing into the pharynx may contribute to chronic cough, while cough may also arise indirectly from reflux via a vago-vagal reflex in some patients. © 2011 Blackwell Publishing Ltd.

Eight thousand COGS were performed, searching for, quantifying and visualizing GOR, and possibly associated oesophageal dismotility or gastric emptying disorders in neonates (15 %), infants (33 %), children 1-4 (20%), 4-8 (20%) and 8-16 years old (14%). Indications were medical or surgical, to diagnoses, assess or follow up GOR with or without treatment. GOR was discovered in 65 % of the cases. A respiratory contamination by GOR aspiration was visualized in 4 % of patients with recurrent respiratory diseases, or near miss from sudden infant death syndrome (SIDS). Pathological patterns of gastric emptying in SIDS are emphasized. Oesophageal motility dysfunctions, primary or related to oesophagitis, are visualized and quantified by scintigraphic imaging. PH-metry and scintigraphy accuracies and their relative positions are discussed. (authors). 117 refs., 8 figs., 5 tabs.

The Pain System in Oesophageal Disorders: Mechanisms, Clinical Characteristics, and Treatment

Directory of Open Access Journals (Sweden)

Christian Lottrup

2011-01-01

Full Text Available Pain is common in gastroenterology. This review aims at giving an overview of pain mechanisms, clinical features, and treatment options in oesophageal disorders. The oesophagus has sensory receptors specific for different stimuli. Painful stimuli are encoded by nociceptors and communicated via afferent nerves to the central nervous system. The pain stimulus is further processed and modulated in specific pain centres in the brain, which may undergo plastic alterations. Hence, tissue inflammation and long-term exposure to pain can cause sensitisation and hypersensitivity. Oesophageal sensitivity can be evaluated ,for example, with the oesophageal multimodal probe. Treatment should target the cause of the patient's symptoms. In gastro-oesophageal reflux diseases, proton pump inhibitors are the primary treatment option, surgery being reserved for patients with severe disease resistant to drug therapy. Functional oesophageal disorders are treated with analgesics, antidepressants, and psychological therapy. Lifestyle changes are another option with less documentation.

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.

Full Text Available 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.

A 6-month-old domestic shorthair female cat was presented with suspected diaphragmatic hernia (DH) that was later confirmed by thoracic radiography. The cat underwent exploratory celiotomy with a diaphragmatic rupture (DR) repair and recovered. Six days later, it was represented with vomiting and anorexia. Megaoesophagus (MO) and gastric dilatation were diagnosed by contrast radiography. A second celiotomy revealed no abnormalities and gastropexy was performed. Endoscopy demonstrated MO, oesophagitis and gastro-oesophageal reflux. MO persisted for several weeks and was an unexpected complication as no association between DR (or DH) and MO has never been described in the veterinary literature. The cat was treated medically with aggressive prokinetic and antacid therapy along with prolonged temporary oesophageal diversion (percutaneous endoscopic gastrostomy tube) with an excellent outcome.

The most important novel findings presented on oesophageal disease in DDW 2015 were the following: 1) GERD: a) hypervigilance seems to be a key pathogenic factor in reflux symptoms refractory to PPI; b) post-reflux swallowing-induced peristaltic waves could be an excellent diagnostic criterion for GERD; c) laryngeal pH-metry is not useful in the diagnosis of extra-oesophageal symptoms; d) the recommendation of weight loss adequately recorded in the clinical reports of patients with GERD and obesity or overweight is an excellent quality indicator and is associated with better outcomes. 2) Barrett's oesophagus: a) persistent low-grade dysplasia in more than one endoscopy and a diagnosis of "indefinite for dysplasia" are associated with a high risk of neoplastic progression; b) narrow-band imaging allows areas of dysplasia on Barrett's oesophagus to be identified with high sensitivity and specificity; c) initial endoscopy fails to identify a high percentage of advanced neoplasms in Barrett's oesophagus. Early re-endoscopy should be considered; d) endoscopists specialized in Barret's oesophagus obtain a much higher yield in the diagnosis of advanced lesions. Patients at high risk-men, older patients, smokers and those with long-segment Barrett's oesophagus-could benefit from follow-up in a referral center. 3) Achalasia: POEM seems safe and effective, independently from patient characteristics (age, comorbidity) and the technical variations used. 4) Eosinophilic esophagitis: topical budesonide and exclusion diets are reasonably effective in PPI non-responders.

The pathogenesis of gastro-oesophageal reflux disease includes increased acid reflux, reduced salivation and impaired peristalsis. This may depend upon the height of acid wave and magnitude of oesophageal mucosal exposure. Interestingly, the effect of site of acid infusion upon salivary secretion and heartburn has not been examined in any detail. To examine whether acid infusion in the upper oesophagus may cause increased salivation and heartburn as compared with acid infusion in the lower oesophagus. Twelve healthy male subjects (mean age 30) received infusions of HCl, citric acid and acetic acid at 10 and 20 cm above the lower oesophageal sphincter (LES) for fixed time periods. Parotid saliva collected periodically and heartburn severity scored using standardized scale. Standard statistical methods (paired t-tests, analysis of variance) were used to determine the significance of results. Acid infusion in the upper oesophagus increased parotid flow rate as compared with that in the lower oesophagus (P heartburn score at 20 cm as well as 10 cm above LES (P heartburn in response to acid infusion in the upper vs. lower part of the oesophagus. 2010 Blackwell Publishing Ltd.

Oesophageal hypervigilance and anxiety can drive symptom experience in chronic oesophageal conditions, including gastro-oesophageal reflux disease, achalasia and functional oesophageal disorders. To date, no validated self-report measure exists to evaluate oesophageal hypervigilance and anxiety. This study aims to develop a brief and reliable questionnaire assessing these constructs, the oesophageal hypervigilance and anxiety scale (EHAS). Questions for the EHAS were drawn from 4 existing validated measures that assessed hypervigilance and anxiety adapted for the oesophagus. Patients who previously underwent high-resolution manometry testing at a university-based oesophageal motility clinic were retrospectively identified. Patients were included in the analysis if they completed the EHAS as well as questionnaires assessing symptom severity and health-related quality of life at the time of the high-resolution manometry. Nine hundred and eighty-two patients aged 18-85 completed the study. The EHAS demonstrates excellent internal consistency (α = 0.93) and split-half reliability (Guttman = 0.87). Inter-item correlations indicated multicollinearity was not achieved; thus, no items were removed from the original 15-item scale. Principal components factor analysis revealed two subscales measuring symptom-specific anxiety and symptom-specific hypervigilance. Construct validity for total and subscale scores was supported by positive correlations with symptom severity and negative correlations with health-related quality of life. The EHAS is a 15-item scale assessing oesophageal hypervigilance and symptom-specfic anxiety. The EHAS could be useful in evaluating the role of these constructs in several oesophageal conditions in which hypersensitivity, hypervigilance and anxiety may contribute to symptoms and impact treatment outcomes. © 2018 John Wiley & Sons Ltd.

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 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 lower oesophageal sphincter (LOS) is a specialized region of the oesophageal circular smooth muscle that allows the passage of a swallowed bolus to the stomach and prevents the reflux of gastric contents into the oesophagus. The anatomical arrangement of the LOS includes semicircular clasp fibres adjacent to the lesser gastric curvature and sling fibres following the greater gastric curvature. Such anatomical arrangement together with an asymmetric intrinsic innervation and distinct proportion of neurotransmitters in both regions produces an asymmetric pressure profile. The LOS tone is myogenic in origin and depends on smooth muscle properties that lead to opening of L-type Ca(2+) channels; however it can be modulated by enteric motor neurons, the parasympathetic and sympathetic extrinsic nervous system and several neurohumoral substances. Nitric oxide synthesized by neuronal NOS is the main inhibitory neurotransmitter involved in LOS relaxation. Different putative neurotransmitters have been proposed to play a role together with NO. So far, only ATP or related purines have shown to be co-transmitters with NO. Acetylcholine and tachykinins are involved in the LOS contraction acting through acetylcholine M(3) and tachykinin NK(2) receptors. Nitric oxide can also be involved in the regulation of LOS contraction. The understanding of the mechanisms that originate and modulate LOS tone, relaxation and contraction and the characterization of neurotransmitters and receptors involved in LOS function are important to develop new pharmacological tools to treat primary oesophageal motor disorders and gastro-oesophageal reflux disease.

Certain foods and drinks such as alcohol, heavily spiced or fatty meals are known to provoke gastro-oesophageal reflux (GOR). This may give rise to symptoms of heartburn, epigastric pain and occasionally oral regurgitation of the gastric contents. Oral regurgitation of gastric juice is important in dentistry because of its association with dental erosion. This study measured oesophageal and oral reflux in 12 healthy subjects after a curry meal taken with alcohol 2 h before sleep. Each subject repeated the test with a bland non-reflux provoking control meal. GOR was measured by recording distal and proximal oesophageal pH on a dual channel, portable pH monitor. Oral pH was measured with a pH sensitive radio-telemetry capsule (RTC) held on the palate in a vacuum formed splint. Signals from the RTC were received by an aerial worn around the head. The pH change produced by GOR was estimated as the percentage time that pH (PTpH) was less than 4 in the distal oesophagus. Similarly, the PTpH was estimated reflux in only two subjects. In one of these subjects the bland meal provoked oral regurgitation with a PTpH < 5.5 of 13.5%. In the remaining subjects little oral regurgitation occurred.

Despite promising evidence that laparoscopic fundoplication provides better short-term relief of gastro-oesophageal reflux disease (GORD) than continued medical management, uncertainty remains about whether benefits are sustained and outweigh risks. To evaluate the long-term clinical effectiveness, cost-effectiveness and safety of laparoscopic surgery among people with GORD requiring long-term medication and suitable for both surgical and medical management. Five-year follow-up of a randomised trial (with parallel non-randomised preference groups) comparing a laparoscopic surgery-based policy with a continued medical management policy. Cost-effectiveness was assessed alongside the trial using a NHS perspective for costs and expressing health outcomes in terms of quality-adjusted life-years (QALYs). Follow-up was by annual postal questionnaire and selective hospital case notes review; initial recruitment in 21 UK hospitals. Questionnaire responders among the 810 original participants. At entry, all had documented evidence of GORD and symptoms for > 12 months. Questionnaire response rates (years 1-5) were from 89.5% to 68.9%. Three hundred and fifty-seven participants were recruited to the randomised comparison (178 randomised to surgical management and 179 randomised to continued medical management) and 453 to the preference groups (261 surgical management and 192 medical management). The surgeon chose the type of fundoplication. Primary: disease-specific outcome measure (the REFLUX questionnaire); secondary: Short Form questionnaire-36 items (SF-36), European Quality of Life-5 Dimensions (EQ-5D), NHS resource use, reflux medication, complications. The randomised groups were well balanced. By 5 years, 63% in the randomised surgical group and 13% in the randomised medical management group had received a total or partial wrap fundoplication (85% and 3% in the preference groups), with few perioperative complications and no associated deaths.

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.

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-99m 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

The development of gastro-oesophageal reflux disease (GORD) is known to be a causative risk factor in the evolution of adenocarcinoma of the oesophagus. The major component of this reflux is gastric acid. However, the impact of low pH on gene expression has not been extensively studied in oesophageal cells. This study utilizes a transcriptomic and bioinformatic approach to assess regulation of gene expression in response to low pH. In more detail, oesophageal adenocarcinoma cell lines were exposed to a range of pH environments. Affymetrix microarrays were used for gene-expression analysis and results were validated using cycle limitation and real-time RT-PCR analysis, as well as northern and western blotting. Comparative promoter transcription factor binding site (TFBS) analysis (MatInspector) of hierarchically clustered gene-expression data was employed to identify the elements which may co-ordinately regulate individual gene clusters. Initial experiments demonstrated maximal induction of EGR1 gene expression at pH 6.5. Subsequent array experimentation revealed significant induction of gene expression from such functional categories as DNA damage response (EGR1-4, ATF3) and cell-cycle control (GADD34, GADD45, p57). Changes in expression of EGR1, EGR3, ATF3, MKP-1, FOSB, CTGF and CYR61 were verified in separate experiments and in a variety of oesophageal cell lines. TFBS analysis of promoters identified transcription factors that may co-ordinately regulate gene-expression clusters, Cluster 1: Oct-1, AP4R; Cluster 2: NF-kB, EGRF; Cluster 3: IKRS, AP-1F. Low pH has the ability to induce genes and pathways which can provide an environment suitable for the progression of malignancy. Further functional analysis of the genes and clusters identified in this low pH study is likely to lead to new insights into the pathogenesis and therapeutics of GORD and oesophageal cancer.

Proton pump inhibitor (PPI)-refractory heartburn may be due to persistent gastro-oesophageal reflux, oesophageal hypersensitivity or functional heartburn (FH). The differentiation between non-erosive reflux disease (NERD) and FH may be very difficult. However, this differentiation is important for appropriate therapeutic management. Dilated intercellular spaces (DIS), papillary elongation (PE) and basal cell hyperplasia (BCH) can be all assessed by light microscopy. Whether these mucosal abnormalities allow the differentiation of NERD from FH in PPI-refractory patients is uncertain. To assess histopathological findings by light microscopy in patients with refractory heartburn to differentiate NERD from FH. Sixty-two patients with PPI-refractory symptoms underwent EGD and MII-pH after pausing PPI medication for 2 weeks before investigation. Twenty-five subjects without upper gastrointestinal symptoms were included as controls. Symptom assessment was based on the reflux disease questionnaire (RDQ). Biopsies were taken 3-5 cm above the gastro-oesophageal junction. DIS, PE, BCH and infiltration of immune cells were evaluated and a sum score was calculated. Based on endoscopy and MII-pH, GERD was diagnosed in 43 patients (NERD: 20; ERD: 23) and FH in 19 patients. There was no difference in symptoms between the groups. Each individual histopathological item was different between the groups (P < 0.0001). Between NERD and FH, the most significant difference was found for DIS and the histopathological sum score (P < 0.001). These findings suggest that oesophageal biopsies are useful to differentiate NERD from FH. Increased DIS and a histological sum score are the most significant histopathological abnormalities in NERD as compared with FH. © 2013 John Wiley & Sons Ltd.

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

Science.gov (United States)

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.

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.

The study and clinical assessment of enterogastric bile reflux has been restricted for want of a simple non-invasive test for its detection and quantification. This paper describes such a test in which biliary excretion scintigraphy has been combined with a milk meal provocation. Two of 10 healthy volunteers studied showed probable reflux of approximately 5 per cent of total initial abdominal field activity. Among 73 patients studied, 37 patients showed definite reflux of up to 47 per cent. Reflux occurred in 19 of 22 post-gastric surgery patients and in 7 of 22 patients with peptic ulcer disease, gastritis or gastro-oesophageal reflux. None of 7 patients with 'non-specific' abdominal pain showed any reflux, but 11 of 22 patients with gallstone disease or previous cholecystectomy showed reflux of up to 35 per cent, including 9 of 11 patients with loss of gallbladder reservoir function.

Conventional 24-h pH monitoring is the gold standard for the diagnosis of non-erosive, non-acidic gastro-esophageal reflux disease. Multichannel Intraluminal Impedance (MII) analysis markedly improves diagnostic accuracy of non-erosive, non-acidic gastro-esophageal reflux disease. However, MII catheters are more expensive than standard catheters. This study aimed to determine the rates of acid or non-acid reflux and by making a retrospective projection, to predict the costs of two algorithms. We retrospectively reviewed the medical data of 102 patients who presented to our hospital with suspected non-erosive GERD and underwent 24 h impedance/pH-monitoring. Demographic characteristics, Demeester scores, number of reflux episodes, and results of impedance analysis were recorded. According to these data, cost was calculated either for the scenario in which impedance measurement was performed solely or following a negative conventional pH monitoring. Thirty-seven of all 102 patients (36.3 %) had a Demeester score greater than 14.7. These patients were assigned as group 1 (acid reflux). The impedance analysis of the remaining 65 patients detected 34 patients (33.3 %) to have more than 50 reflux episodes over a period of 24 h and assigned as Group 2, and 31 patients (30.4 %) had no reflux (group 3). The cost of the single- step algorithm using MII catheter was calculated as $15,300, while the total cost of two-step scenario would have been predicted as $16,890. Our study showed that an initial conventional pH monitoring can make the diagnosis of GERD in only one third of the patients with suspected non-erosive GERD. In nearly two-thirds of patients, however, repeated procedures and use of impedance catheters are needed. It is clear that this algorithm has certain drawbacks with regard to cost, patient comfort, and workforce loss.

The fundamental mechanisms underlying erosive oesophagitis and subsequent development of Barrett's oesophagus (BO) are poorly understood. Here, we investigated the contribution of specific components of the gastric refluxate on adhesion molecules involved in epithelial barrier maintenance. Cell line models of squamous epithelium (HET-1A) and BO (QH) were used to examine the effects of bile acids on cell adhesion to extracellular matrix proteins (Collagen, laminin, vitronectin, fibronectin) and expression of integrin ligands (α 3 , α 4, α 5 , α 6 and α ν ). Experimental findings were validated in human explant oesophageal biopsies, a rat model of gastroesophageal reflux disease (GORD) and in patient tissue microarrays. The bile acid deoxycholic acid (DCA) specifically reduced adhesion of HET-1A cells to vitronectin and reduced cell-surface expression of integrin-α ν via effects on endocytic recycling processes. Increased expression of integrin-α v was observed in ulcerated tissue in a rat model of GORD and in oesophagitis and Barrett's intestinal metaplasia patient tissue compared to normal squamous epithelium. Increased expression of integrin-α ν was observed in QH BO cells compared to HET-1A cells. QH cells were resistant to DCA-mediated loss of adhesion and reduction in cell-surface expression of integrin-α ν . We demonstrated that a specific component of the gastric refluxate, DCA, affects the epithelial barrier through modulation of integrin α ν expression, providing a novel mechanism for bile acid-mediated erosion of oesophageal squamous epithelium and promotion of BO. Strategies aimed at preventing bile acid-mediated erosion should be considered in the clinical management of patients with GORD. © 2017 The Authors.

Using dynamic, gradient echo sequences (B-FFE) in the coronal, sagittal and axial planes, the bolus passages of buttermilk spiked with gadolinium chelate were tracked. MRI, pH-metry and manometry were performed within 31 days and results were compared. MRI results were concordant with pH-metry in 82% (23/28) of patients diagnosed with abnormal oesophageal acid exposure by pH-metry. Five patients demonstrated typical symptoms of GERD and had positive findings with pH monitoring, but false negative results with MRI. In four of six patients (67%), there was a correct diagnosis of oesophageal motility disorder, according to manometric criteria, on dynamic MRI. The overall accuracy of MRI diagnoses was 79% (27/34). A statistically significant difference was found between the size of hiatal hernia, grade of reflux in MRI, and abnormal acid exposure on pH-monitoring. MR fluoroscopy may be a promising radiation-free tool in assessing the functionality and morphology of the GE junction. (orig.)

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.

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 99m Tc 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. (author)

Full Text Available Abstract Background Gastroesophageal reflux disease (GORD can cause respiratory disease in children from recurrent aspiration of gastric contents. GORD can be defined in several ways and one of the most common method is presence of reflux oesophagitis. In children with GORD and respiratory disease, airway neutrophilia has been described. However, there are no prospective studies that have examined airway cellularity in children with GORD but without respiratory disease. The aims of the study were to compare (1 BAL cellularity and lipid laden macrophage index (LLMI and, (2 microbiology of BAL and gastric juices of children with GORD (G+ to those without (G-. Methods In 150 children aged Results BAL neutrophil% in G- group (n = 63 was marginally but significantly higher than that in the G+ group (n = 77, (median of 7.5 and 5 respectively, p = 0.002. Lipid laden macrophage index (LLMI, BAL percentages of lymphocyte, eosinophil and macrophage were similar between groups. Viral studies were negative in all, bacterial cultures positive in 20.7% of BALs and in 5.3% of gastric aspirates. BAL cultures did not reflect gastric aspirate cultures in all but one child. Conclusion In children without respiratory disease, GORD defined by presence of reflux oesophagitis, is not associated with BAL cellular profile or LLMI abnormality. Abnormal microbiology of the airways, when present, is not related to reflux oesophagitis and does not reflect that of gastric juices.

Both open and laparoscopic myotomies have been used in the treatment of achalasia. Postoperative gastro-oesophageal reflux is among the commonly reported side effects of myotomy. The addition of an antireflux procedure to the standard surgical approach has given rise to controversy. The objective of our study was to determine whether or not an antireflux procedure should be used in addition to Heller myotomy. Over the period from 1980 to 1990, 94 patients (mean age: 47.9 years) with achalasia underwent Heller myotomy calibrated by intraoperative oesophageal manometry without fundoplication. In 1999-2000, all patients filled in a clinical questionnaire: all underwent radiographic oesophageal imaging, oesophageal manometry, ambulatory 24-h oesophageal pH monitoring, and oesophagogastroduodenoscopy, when necessary. Ten healthy age-matched subjects were compared in the manometric and radiological studies. Myotomy improved the clinical profiles and instrumental data results in all patients. Gastro-oesophageal reflux was present in 10 patients (10.6%); none of these 10 subjects presented oesophagitis. Heller open myotomy yields good long-term results. Intraoperative manometric calibration reduces the side effects of myotomy, such as gastro-oesophageal reflux. The addition of fundoplication is not justified in all patients.

Acid pockets at the gastro-oesophageal junction escape buffering from meals in the stomach. Combining high-dose antacid with alginate may therefore be of benefit in gastro-oesophageal reflux disease. To characterize the antacid and raft-forming properties of Rennie alginate suspension (containing high-dose antacid and alginate; Bayer Consumer Care, Bladel, the Netherlands). The in vitro acid-neutralizing capacity of Rennie algniate was compared with Gaviscon (Reckitt Benckiser, Slough, UK) by pH-recorded HCl titration. Alginate raft weight formed in vitro at different pH was used to evaluate the pH dependency of raft formation with each product. A double-blind, placebo-controlled, randomized crossover study also compared the antacid activity of Rennie alginate vs. placebo in vivo using continuous intragastric pH monitoring in 12 healthy fasting volunteers. Compared with Gaviscon, Rennie alginate had a higher acid-neutralizing capacity, greater maximum pH and longer duration of antacid activity in vitro. However, the two products produced comparable alginate rafts at each pH evaluated. In vivo, Rennie alginate provided rapid, effective and long-lasting acid neutralization, with an onset of action of <5 min, and duration of action of almost 90 min. The dual mode of action of Rennie alginate offers an effective treatment option for mild symptomatic gastro-oesophageal reflux disease particularly considering recent findings regarding 'acid pockets'.

Oesophageal elongation with traction sutures (FOKER procedure in a newborn baby with long-gap oesophageal atresia (LGEA: Maybe too early, maybe too dangerous?

2013-01-01

Full Text Available In children with long gap oesophageal atresia (LGEA, the FOKER technique (oesophageal elongation with traction sutures has been criticized for its high complication rate. We advocate analysing such problems to increase the safety in the future. The present case report will focus on timing. A female newborn (3000 g with LGEA (gap of 5 cm was delivered in an outward hospital. On day two of life, she received traction sutures on both pouches. By day five, all sutures had torn out, and a primary anastomosis was attempted. However, it leaked severely. Thus, on day ten, the oesophagus was approached from the neck converting the proximal end into a spit fistula and closing the distal end blindly. Furthermore, the gastro-oesophageal (GE- junction was wrapped with a Teflon sling. When the baby arrived in our institution, she suffered from cavernous oesophageal masses extending from the thoracic inlet down to the diaphragm and fistulas draining them into the neck as well as into the right lung. Moreover, the Teflon sling had dislodged allowing for GE-reflux. In several stages, the oesophageal remnants were resected without any complications. Finally, Prof. Alaa Hamza performed a colonic interposition, which is working well today. In conclusion, the present case aims to caution paediatric surgeons to apply traction sutures for oesophageal elongation in newborns with LGEA.

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

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.

Christiansen, T.; Thommesen, P.

An investigation for biliary tract calculi and food-stimulated gastro-oesophageal reflux was carried out in 37 patients with duodenal diverticula demonstrated by barium examination. Sixty per cent of the diverticula were located in the descending part of the duodenum. Biliary tract calculi were demonstrated in 38 per cent and food-stimulated gastro-oesophageal reflux in 81 per cent of the patients. The detection of a duodenal diverticulum should result in a supplementary investigation for gallstones and gastrooesophageal reflux and its sequelae.

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.

The gastro-esophageal reflux barrier: biophysical analysis on 3D models of anatomy from magnetic resonance imaging.

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.

To compare chemotherapy first (group 1) versus self-expanding metal stent first (group 2) for the management of malignant dysphagia in unresectable oesophageal or gastro-oesophageal junction cancer. Patients from two university hospitals with severe malignant dysphagia (dysphagia score ≥ 2) uneligible for surgery or radiochemotherapy were evaluated retrospectively. Forty-two patients were included in group 1, and 29 in group 2. After 4 weeks, dysphagia scores improved by at least 1 point in 67% of patients in group 1 versus 93% in group 2 (p=0.01); 48% of patients in group 1 were able to eat solid food versus 68% in group 2 (p=0.054). In group 1, a self-expanding metal stent was secondarily placed in 18 patients (42.9%), whereas in group 2 dysphagia required a second self-expanding metal stent placement in 33.3% of patients. Chemotherapy as the first treatment may be a valid option, avoiding self-expanding metal stent insertion in half of the patients. Copyright © 2013 Editrice Gastroenterologica Italiana S.r.l.

Functional dyspepsia (FD) and non-erosive reflux disease (NERD): overlapping or discrete entities?

LENUS (Irish Health Repository)

Quigley, Eamonn M M

2012-02-03

As the incidence of both gastric cancer and peptic ulcer disease have declined, that of gastro-oesophageal reflux disease (GORD) and non-ulcer, or functional dyspepsia (FD) have reached virtually epidemic proportions. As we come to appreciate the expression of these disorders in the community, the real spectrum of each disease has become evident. FD and non-erosive reflux disease (NERD), the most prevalent manifestation of GORD, frequently overlap. Where then does GORD end and FD begin? Is it realistic, or even clinically relevant, to attempt a clear separation between these entities? These are more than issues of mere semantics; therapeutic options may be dictated by the classification of the patient as one or the other. Recent work indicates clearly that NERD is a heterogeneous disorder incorporating some patients who may well harbour subtle manifestations of oesophagitis and others who have entirely normal 24-hour pH studies. These differences may be crucial to the concept of NERD\\/FD overlap. While evidence in support of this concept is far from complete, it would appear that this overlap is most relevant to those NERD patients who do not exhibit abnormal esophageal acid exposure. These patients truly belong in the spectrum of functional gastrointestinal disorders rather than in GORD; attempts to shoe-horn these individuals into the spectrum of GORD will result in therapeutic disappointment and surgical disaster.

To assess the accuracy of a new ingestion protocol for capsule endoscopy (CE) in evaluating patients with gastro-oesophageal reflux disease (GORD). Oesophago-gastroduodenoscopy (OGD) was performed 1 week prior to CE. The first 28 subjects swallowed the capsule following the original ingestion protocol (OIP) and the subsequent 30 subjects following a simplified ingestion protocol (SIP). CE videos were reviewed by two independent investigators who were blinded to the OGD findings. Of 48 patients included, 24 were diagnosed with reflux oesophagitis (67% male, mean age 49.5+/-13 years) and 24 with Barrett oesophagus (BO) (88% male, 55.6+/-10 years) by OGD. In addition, 10 asymptomatic healthy controls (50% male, 45.8+/-7.1 years) were included. Oesophageal transit time was faster in patients using the SIP compared to the OIP (126+/-26 s versus 214+/-33; p=0.04). Complete evaluation of the Z-line was possible in 19/28 (68%) of the OIPs compared to 28/30 (93%) of the SIPs (p=0.04). Sensitivity for detecting any oesophageal abnormality was higher in the SIP group than in the OIP group (97% versus 89%; p=0.11). Overall, CE detected oesophagitis in 22/24 patients (sensitivity, 92%; specificity, 88%) and BO in 23/24 patients (sensitivity, 96%; specificity, 91%). Furthermore, 41/44 (93%) preferred CE over OGD and experienced less discomfort and pain during CE. CE is an accurate method for detecting mucosal oesophageal abnormalities. The new ingestion protocol improves the visualization of the Z-line, which is likely to increase the diagnostic yield of CE.

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.

Treatment of gastro esophageal reflux disease (GERD) is becoming a challenge for medical profession. Proton pump inhibitors (PPIs) are commonly recommended but many disadvantages of these drugs are being reported, particularly when used for long term. Transient lower esophageal sphincter relaxations (TLESRs) are important cause of acid reflux. Gastric distention in upper stomach is the strongest stimulus for generation of TLESRs and is aggravated by intake of food in between meals. In an earlier cases report, two meals a day with intake of only fluids in between was suggested as a remedy for GERD. Present pilot study was conducted on 20 patients with endoscopically proven reflux esophagitis (Los Angles Grade a, b or c), who followed our advice to take meal twice a day with consumption of only soft drinks (fruit juices, tea, coffee, water, etc) in between and no medication for two weeks. On 14th day 15 patients (75%) were free of reflux symptoms, 2 (10%) had partial improvement and 3 (15%) reported no difference. It is concluded that two meals a day with intake of only fluids in between, whenever the patient feels hungry or thirsty, is a useful dietary regimen for the management of GERD. Further investigations are needed to confirm the benefits of this physiological lifestyle change.

Non-erosive reflux disease (NERD) patients are more sensitive than erosive esophagitis patients to weakly acidic reflux and to the presence of gas in the refluxate. Intra-esophageal acid perfusion sensitizes esophageal receptors to mechanical and chemical stimuli. To establish whether acid sensitization plays a role in the perception of weakly acidic and mixed reflux episodes, 29 NERD patients, responders and 14 non-responders to proton pump inhibitors (PPIs), underwent pH-impedance monitoring. Non-responders repeated the study while on PPIs. To assess the effect of acid exposure on symptom perception, the time period with pH below 4 was measured in 15- and 30-minute time-windows preceding the onset of each reflux episode. Considering weakly acidic and mixed refluxes, both in responder and non-responder patients (off PPIs), the symptomatic refluxes were preceded by a significantly higher cumulative acid exposure than the asymptomatic refluxes. In all patients, following acid reflux, the percentage of symptomatic weakly acidic reflux episodes was significantly higher than that of asymptomatic refluxes. Non-responder patients, off-treatment, were characterized by a lower proportion of weakly acidic reflux and mixed reflux episodes. In the non-responder patients on PPI, only mixed and weakly symptomatic reflux episodes were preceded by a higher cumulative acid exposure. In NERD patients, spontaneous acid reflux enhances subsequent reflux perception, regardless of acidity or liquid/mixed composition of episodes; in non-responder patients on PPIs, only the perception of mixed and weakly acidic reflux episodes seems to be mediated by a preceding acid exposure. © 2013 John Wiley & Sons Ltd.

The mechanisms that cause acid reflux in patients with non-erosive reflux disease (NERD), including those that determine how acid extends proximally, are not yet clear. Concurrent esophageal manometry and pH monitoring were performed for 3 h after a meal in 13 patients with NERD, 12 with mild reflux esophagitis (RE), and 13 healthy subjects (HS). Transient lower esophageal sphincter (LES) relaxation (TLESR) was the major mechanism of acid reflux in all three groups. LES pressure did not differ between the groups. At 2 cm above the LES, there were no differences between the three groups in the number of TLESR-related acid reflux episodes, rate of TLESRs and rate of acid reflux during TLESR. However, at 7 cm above the LES, the rate of acid reflux during TLESRs was significantly higher in patients with NERD (mean ± SEM 42.3 ± 4.8) than in those with mild RE (28.0 ± 3.8) and HS (10.8 ± 2.5). TLESRs are the sole motor events underlying acid reflux episodes in patients with NERD. Acid extends proximally more readily in patients with NERD than in HS and those with mild RE.

The objective of this study was to formulate and evaluate the lansoprazole (LPZ)-loaded microparticles to prevent nocturnal acid breakthrough in the case of gastro-esophageal reflux disease (GERD). The microparticulate delivery system was prepared by solvent evaporation method using Eudragit RS100 as a matrix polymer followed by enteric coated with Eudragit S100 and hydroxypropyl methylcellulose phthalate HP55 using spray drying method. The enteric coated microparticles were stable in gastric pH condition. In vivo pharmacokinetic and pharmacodynamic studies in male Wistar rats demonstrated that enteric coated microparticles sustained release of LPZ and promoted ulcer healing activity. In other words, the microparticulate dosage form provided effective drug concentration for a longer period as compared to conventional extended release dosage form, and showed sufficient anti-acid secretion activity to treat acid related disorders including the enrichment of nocturnal acid breakthrough event based on a once daily administration.

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.

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 [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.

There is no data on the prevalence and the association of gastro esophageal reflux disease (GERD) with toxic fume inhalation. Therefore, we aimed to evaluate the frequency distribution of GERD symptoms among the individuals with mild respiratory disorder due to the past history of toxic fume exposure to sulfur mustard (SM). In a historical cohort study, subjects were randomly selected from 7000 patients in a database of all those who had a history of previous exposure to a single high dose of SM gas during war. The control group was randomly selected from adjacent neighbors of the patients, and two healthy male subjects were chosen per patient. In this study, we used the validated Persian translation of Mayo Gastroesophageal Reflux Questionnaire to assess the frequency distribution of reflux disease. Relative frequency of GERD symptoms, was found to be significantly higher in the inhalation injury patients with an odds ratio of 8.30 (95% confidence interval [CI]: 4.73-14.55), and after adjustment for cigarette smoking, tea consumption, age, and body mass index, aspirin and chronic cough the odds ratio was found to be 4.41 (95% CI: 1.61-12.07). The most important finding of our study was the major GERD symptoms (heartburn and/or acid regurgitation once or more per week) among the individuals with the past history of exposure to SM toxic gas is substantially higher (4.4-fold) than normal populations.

Esophageal Dysmotility, Gastro-esophageal Reflux Disease, and Lung Transplantation: What Is the Evidence?

Lung transplantation is an effective and life-prolonging therapy for patients with advanced lung disease (ALD). However, long-term patient survival following lung transplantation is primarily limited by development of an inflammatory and fibrotic process involving the lung allograft known as bronchiolitis obliterans syndrome (BOS). Although the precise cause of BOS remains uncertain and is likely multifactorial, chronic aspiration of gastro-duodenal contents is one possible contributing factor. Multiple small, cross-sectional studies performed over the past two decades have reported a high prevalence of gastro-esophageal reflux disease (GERD) and esophageal dysmotility in the ALD population and several investigations suggest the prevalence may increase following lung transplantation. More recent studies evaluating the direct effect of gastro-duodenal contents on airways have demonstrated a possible biologic link between GERD and BOS. Despite the recent advances in our understanding of BOS, further investigations are needed to establish GERD as a causative factor in its development. This review will discuss the existing literature that has identified an association of GERD with ALD and post-transplant populations, with a focus on recent advances in the field.

BACKGROUND AND PURPOSE Gastro-oesophageal reflux is predominantly caused by transient lower oesophageal sphincter relaxation (TLOSR) and GABAB receptor stimulation inhibits TLOSR. Lesogaberan produces fewer CNS side effects than baclofen, which has been attributed to its affinity for the GABA transporter (GAT), the action of which limits stimulation of central GABAB receptors. To understand the structure–activity relationship for analogues of lesogaberan (3-aminopropylphosphinic acids), and corresponding 3-aminopropyl(methyl)phosphinic acids, we have compared representatives of these classes in different in vitro and in vivo models. EXPERIMENTAL APPROACH The compounds were characterized in terms of GABAB agonism in vitro. Binding to GATs and cellular uptake was done using rat brain membranes and slices respectively. TLOSR was measured in dogs, and CNS side effects were evaluated as hypothermia in mice and rats. KEY RESULTS 3-Aminopropylphosphinic acids inhibited TLOSR with a superior therapeutic index compared to 3-aminopropyl(methyl)phosphinic acids. This difference was most likely due to differential GAT-mediated uptake into brain cells of the former but not latter. In agreement, 3-aminopropyl(methyl)phosphinic acids were much more potent in producing hypothermia in rats even when administered i.c.v. CONCLUSIONS AND IMPLICATIONS An enhanced therapeutic window for 3-aminopropylphosphinic acids compared with 3-aminopropyl(methyl)phosphinic acids with respect to inhibition of TLOSR was observed and is probably mechanistically linked to neural cell uptake of the former but not latter group of compounds. These findings offer a platform for discovery of new GABAB receptor agonists for the treatment of reflux disease and other conditions where selective peripheral GABAB receptor agonism may afford therapeutic effects.

Eosinophilic oesophagitis is characterised by age-dependent symptoms mimicking gastrooesophageal reflux disease, a distinct endoscopic appearance and a histological picture with extensive infiltration of eosinophils in the oesophageal mucosa. Eosinophilic oesophagitis is more frequently seen...... in males, and patients often belong to the paediatric or adolescence age groups. The exact prevalence of eosinophilic oesophagitis is unknown, but it has been suggested that the United States has a higher prevalence than Europe. Several treatment algorithms have been suggested, including elemental diets......, oral steroids, inhaled (swallowed) steroids, and leucotriene receptor antagonists. Detailed information on the eosinophilic inflammatory processes in the oesophageal mucosa was initially obtained from animal models, in particular with regard to the role of interleukin-5 and the chemokine eotaxin-1...

The use of biologics targeted to the human epidermal growth factor receptor 2 (HER2) protein is the latest addition to the armamentarium used to fight advanced gastric or gastro-oesophageal junction adenocarcinoma. The decision to treat with the biologic trastuzumab is completely dependent on HER2 testing of tumour tissue. In 2017, the College of American Pathologists, American Society for Clinical Pathology and the American Society of Clinical Oncology jointly published guidelines for HER2 testing and clinical decision making in gastro-oesophageal adenocarcinoma. The Association of Clinical Pathologists Molecular Pathology and Diagnostics Committee has issued the following document as a commentary of these guidelines and, in parallel, to provide guidance on HER2 testing in National Health Service pathology departments within the UK. This guidance covers issues related to case selection, preanalytical aspects, analysis and interpretation of such HER2 testing. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The cause of idiopathic pulmonary fibrosis (IPF) remains unknown, yet gastro-esophageal reflux disease (GERD) is highly prevalent in this population. GERD prevalence was studied, and esophageal function tests (EFT) were assessed in Chinese IPF patients. We prospectively studied 69 IPF patients who undertook both stationary High Resolution esophageal Manometry/Impedance (HRiM) and 24-hour esophageal Multi-Channel Intraluminal Impedance with pH Recordings (MII/pH). Patients were divided into GERD+ and GERD- groups according to pH results. Controls were HRiM treated healthy volunteers, and patients without IPF received HRiM and MII/pH diagnosed with GERD. 69 IPF patients, 62 healthy volunteers, and 88 IPF negative GERD patients were selected. GERD prevalence in IPF was 43/69 (62.3%), and 58.1% of patients presented with at least one typical symptom. Symptoms had a sensitivity of 58.1%, a specificity of 61.6%, a positive predictive value of 71.4% and a negative predictive of 47.1%. Compared with healthy volunteers, IPF patients had significantly decreased lower esophageal sphincter pressure (LESP), upper esophageal sphincter pressure (UESP) and complete bolus transit rate (CBTR). By contrast, IPF patients had increased total bolus transit time and prevalence of weak peristalsis. MII/pH showed that one third of IPF patients had abnormal distal and proximal reflux, especially non-acid reflux. Compared with GERD patients without IPF, GERD patients with IPF had significantly decreased CBTR and UESP with increased bolus exposure time. GERD prevalence in IPF was high, but symptoms alone were an unreliable predictor of reflux. IPF patients had lower LESP and UESP, impaired esophageal peristalsis and bolus clearance function with more proximal reflux events.

Gastro-esophageal reflux (GOR) may contribute to lung disease in children with cystic fibrosis (CF). There is conflicting evidence regarding the effect of chest physiotherapy (CPT) in the head-down position on GOR. Furthermore, there is currently no evidence on the impact of physiotherapy on GOR as assessed by pH-multichannel intraluminal impedance (pH-MII). (1) To characterize GOR in young children with CF. (2) To determine whether the head-down position during physiotherapy exacerbates GOR. Children were studied using pH-MII monitoring over 24-hr, during which they received two 20-min sessions of CPT. One session was performed in "modified" drainage positions with no head-down tilt and the alternate session in "gravity-assisted" drainage positions, which included 20° head-down tilt. Twenty children with CF (8 males), median age 12 months (range 8-34) were recruited. A total of 1,374 reflux episodes were detected in all children, of which 869 (63%) were acid and 505 (37%) were non-acid. Seventy-two percent of the episodes migrated proximally. During CPT, there was no significant difference between total number of reflux episodes in the modified or gravity-assisted positions, median [inter-quartile range (IQR)] 1 (0-2.5) compared to 1 (0.75-3) episode, respectively, P = 0.63. There was also no significant difference between the number of reflux episodes which migrated proximally, median (IQR) 1 (0-2) compared to 0 (0-2) episodes, respectively, P = 0.75. In young children with CF, GOR is primarily acidic and proximal migration is common. Physiotherapy in the head-down position does not appear to exacerbate GOR. The impact of GOR on lung disease remains to be elucidated. Copyright © 2011 Wiley Periodicals, Inc.

Calcium chloride is an essential calcium channel agonist which plays an important role in the contraction of muscles by triggering calcium channel. First time hypothesized about its role in the treatment of GER (gastro-esophageal reflux) and vomiting disorder due to its local action. There are two objectives covered in this study as first, the development and optimization of floating formulation of calcium chloride and another objective was to evaluate optimized formulation through gamma scintigraphy in human subjects. Gastro retentive formulation of calcium chloride was prepared by direct compression method. Thirteen tablet formulations were designed with the help of sodium chloride, HPMC-K4M, and carbopol-934 along with effervescing agent sodium bicarbonate and citric acid. Formulation (F8) fitted best for Korsmeyer-Peppas equation with an R 2 value of 0.993. The optimized formulation was radiolabelled with 99m Tc-99 m pertechnetate for its evaluation by gamma scintigraphy. Gastric retention (6 h) was evaluated by gamma scintigraphy in healthy human subjects and efficacy of present formulation confirmed in GER positive human subjects. Gamma scintigraphy results indicated its usefulness in order to manage GERD. Stability studies of the developed formulation were carried out as per ICH guidelines for region IV and found out to be stable for 24 months.

Patients with chronic autoimmune atrophic gastritis (CAAG) often refer digestive symptoms and are prescribed antisecretory medications. Aims were to investigate: (i) gastro-esophageal reflux (GER), (ii) psychopathological profile, (iii) frequency of use and clinical benefit of antisecretory drugs. Prospective observational study on 41 CAAG patients who underwent: 24 h multichannel intra-luminal impedance-pH (MII-pH) monitoring off-therapy, standardized medical interview and psychological questionnaire (i.e., SCL-90R). The medical interview was repeated at least 1 month after MII-pH in patients who were using antisecretory drugs. Statistical analysis was performed calculating median (10th-90th percentiles) and risk ratios (RR) with 95% confidence interval. Median intra-gastric pH was 6.2 (4.6-7.0). One patient had acid reflux (AC) associated with symptoms, five had increased total reflux number and four had symptoms associated to non-acid reflux (NA) (patients referred as 'GER positive'). Using patients 'GER negative' with normal SCL-90R as reference, the RR of being symptomatic in patients GER positive was 2.1 (1.1-4.1) if SCL-90R was normal and 0.9 (0.5-1.7) if it was altered (difference in RR significant being p = 0.04). Seventeen/28 (61%) symptomatic patients were on antisecretory drugs, which were stopped in 16 of them according to results of MII-pH and clinical evaluation after 574 days (48-796) showed that symptoms were unchanged. In patients with CAAG (i) AC reflux rarely occurred whereas increased NA reflux was not infrequent both being related to symptoms in some patients, (ii) psychopathological profile has a role in symptoms' occurrence, (iii) antisecretory drugs were generally inappropriately used and clinically ineffective. © 2015 John Wiley & Sons Ltd.

Non-erosive reflux disease (NERD) is the most common presentation of gastroesophageal reflux disease. Although acid reflux is the most important cause of symptom generation in NERD patients, non-acid reflux is also associated with reflux symptoms. The temporal relation between symptoms and reflux episodes is of importance in evaluating the results of combined pH-impedance monitoring in NERD patients. Mucosal hypersensitivity and mechanical stimulation due to great volume of non-acid reflux ar...

To assess the impact of sarcopenia and alterations in body composition parameters (BCPs) on survival after surgery for oesophageal and gastro-oesophageal junction cancer (OC). 200 consecutive patients who underwent resection for OC between 2006 and 2013 were selected. Preoperative CTs were used to assess markers of sarcopenia and body composition (total muscle area [TMA], fat-free mass index [FFMi], fat mass index [FMi], subcutaneous, visceral and retrorenal fat [RRF], muscle attenuation). Cox regression was used to assess the primary outcome parameter of overall survival (OS) after surgery. 130 patients (65 %) had sarcopenia based on preoperative CT examinations. Sarcopenic patients showed impaired survival compared to non-sarcopenic individuals (hazard ratio [HR] 1.87, 95 % confidence interval [CI] 1.15-3.03, p = 0.011). Furthermore, low skeletal muscle attenuation (HR 1.91, 95 % CI 1.12-3.28, p = 0.019) and increased FMi (HR 3.47, 95 % CI 1.27-9.50, p = 0.016) were associated with impaired outcome. In the multivariate analysis, including a composite score (CSS) of those three parameters and clinical variables, only CSS, T-stage and surgical resection margin remained significant predictors of OS. Patients who show signs of sarcopenia and alterations in BCPs on preoperative CT images have impaired long-term outcome after surgery for OC. (orig.)
