The Changing Epidemiology of Gastroesophageal Reflux Disease: Are Patients Getting Younger?

Benefit of radiofrequency ablation after widespread endoscopic resection of neoplastic Barrett's esophagus in daily practice

Background

High-grade dysplasia (HGD) and intramucosal carcinoma (IMC) in Barrett’s esophagus (BE) are now well-established indications for endoscopic resection (ER). Radiofrequency ablation (RFA) can be combined with ER in case of flat or long-segment BE ablation. We report here our experience of complementary RFA after widespread ER of neoplastic BE in daily practice.

Method

We retrospectively reviewed data of 89 patients, treated between 2006 and 2013 by ER alone (group 1) or by ER combined with RFA (group 2).

Results

Fifty-five patients in group 1 (7F/48M, mean age 68 years) underwent widespread ER with eradication of residual non-dysplastic BE. Complete eradication of HGD/IMC and intestinal metaplasia (IM) was achieved in 32/32 (100%) and 48/55 (87.3%) patients, respectively. Thirty-four patients in group 2 (3F/31M, mean age 67 years) had a multimodal treatment strategy, with widespread ER followed by RFA. Mean Prague classification of BE in this group was significantly longer (C4.4M6.6 vs. C2.7M4.5, P<0.001). Complete eradication of HGD/IMC and non-dysplastic BE was confirmed in 26/27 (96.3%) and 20/34 (58.8%) patients, respectively. There was no significant difference between groups concerning adverse events (16.4% vs. 23.5%, P=0.58) or recurrence rate of HGD/IMC (9.1% vs. 14.7%, P=0.42). The mismatch rate between preoperative and final histological diagnosis was high in both groups, at 45.5% and 26.5%.

Conclusions

A combination of ER and RFA can treat significantly longer neoplastic BE than ER alone, with the same efficiency and safety. Widespread ER, in contrast, is the only method of obtaining a reliable histological diagnosis.

Epidemiological investigation, extraesophageal symptoms and risk factors of gastroesophageal reflux disease in Kashgar, Xinjiang, China

OBJECTIVE

To explore the incidence, distribution characteristics and related symptoms of gastroesophageal reflux disease (GERD) as well as its related risk factors in Kashgar, Xinjiang.

METHODS

From March 2020 to October 2020, a questionnaire survey was conducted among 5,080 permanent residents aged 18-80 years in Kashgar using cluster sampling and stratified sampling methods. The content included basic information, accompanying symptoms and diseases, living, customs and eating habits, and Gastroesophageal Reflux Disease Questionnaire score, etc. Results: The prevalence of GERD in Kashgar was 23.4% (1187/5080), and the proportions of patients with reflux symptoms lasting 1 day, 2-3 days and 4-7 days within a week were 12.5%, 6.4% and 4.4%, respectively. The proportion of patients showing symptoms in the GERD group was significantly higher than that in the non-GERD group (P<0.05). The proportion of people who are overweight or obese, take alcohol drink, eat, constipate, or take various chronic disease drugs in the GERD group is higher than that in the non-GERD group. The proportion of people in the GERD group who often eat sweet foods, pickled products, roasted products, spicy foods and meat, or drink coffee, acidic beverages, and cold drinks was higher than that in the non-GERD (P<0.05). The proportion of people in the GERD group who regularly consume fish, milk, eggs, vegetables, and fruits was significantly lower than that in non-GERD group (P<0.05). Logistic regression analysis found that Uyghur nationality (for the Han nationality), age (for the 30-39 years group), drinking, overeat, constipation, and frequent medication were risk factors (P<0.05, OR>1). Multivariate logistic regression analysis found that sweets, baked products, cold drinks, and spicy foods were independent risk factors (P<0.05, OR>1). Eggs and vegetables were protective factors (P<0.05, OR<1).

CONCLUSION

The high incidence of GRED in Kashgar, Xinjiang may be related to the local living environment, and life and eating habits.

Adverse events associated with transoral incisionless fundoplication (TIF) for chronic gastroesophageal reflux disease: a MAUDE database analysis

BACKGROUND

Transoral incisionless fundoplication (TIF) has been used for treating chronic gastroesophageal reflux disease (GERD) refractory to medical therapy. We aim to investigate the complications associated with TIF using a national database.

METHODS

We analyzed post-marketing surveillance data from the FDA Manufacturer and User Facility Device Experience (MAUDE) database from Jan 2011 through Jan 2021.

RESULTS

During the study period, approximately 95 event cases reported to the FDA. Approximately 131 patient complications were identified. The number of adverse events declined from 2011 to 2016 (R² = 0.96) but increased from 2016 to 2020 (R² = 0.99). The most common adverse event was perforation (19.8%), followed by laceration 17.6%, bleeding (9.2%), and pleural effusion (9.2%). The most common patient complications were treated using endoscopic clips (12.3%), chest tube or drain insertion (12.3%), use of endoscopic retriever device (11.1%), esophageal stent (8.6%), and emergent or open surgery (11.1%).

CONCLUSIONS

Adverse events from TIF range from mild to severe. Further research is needed to develop approaches aimed at reducing patient risks.

The Restoration of Severe Generalized Dental Erosive Wear using Direct Composite: A Case Report

Introduction:

This case report describes a conservative restorative approach in the management of severe generalized tooth wear.

Case report:

The male, aged 57 years, was mainly concerned with the poor appearance of his teeth with short and discolored upper incisors. History revealed that he suffered from gastric reflux for 25 years, for which he was prescribed Ranitidine and was advised to self-medicate with cider vinegar. Furthermore, he divulged that he ground his teeth at night and during the day and had a high intake of carbonated cola drinks. On examination, dentine was exposed in several areas, and to a significant extent, on the incisal aspects of the lower incisors, the palatal surfaces of the upper incisors, and the occlusal surfaces of the molars. Mandibular tori were present.

The primary diagnosis was erosive tooth wear with elements of attrition and abrasion. The intervention included dietary advice and restoration with direct composite resin at an increased occlusal vertical dimension of 1.5mm on the retruded axis. The patient reported no functional problems and was pleased with the aesthetic result.

Conclusion:

Vinegar is promoted to have health benefits, especially with respect to glucose response, but the dental implications are overlooked. This paper reviews the literature on vinegar as a medicament and considers its role as a co-factor for erosion in this case. The clinical steps used to restore the eroded dentition by direct composite are described. The use of this approach is a safe, conservative and successful treatment option without recourse to complex and biologically costly conventional alternatives. The application of direct composite in tooth wear cases meets the European consensus requirements.

Gastroesophageal Reflux Disease-Associated Chronic Cough: A Population-Based Analysis of Patient Presentations in the United States

Gastroesophageal reflux disease is an extremely prevalent illness in the United States; however, clinicians report that its association with chronic cough is often overlooked and undiagnosed. We used the CERNER Health Facts® database to analyze the statistical prevalence. Our findings indicate that there is a minority of patients who are untreated for this common complaint. We propose considering this on the differential diagnosis and following current treatment guidelines with proton pump inhibitors to effectively treat this complaint.

Additional fundophrenicopexia, after Nissen fundoplication, reduces postoperative dysphagia and re-operation rate in the long-term follow up

Background

Various technical modifications of Nissen fundoplication (NF) that aim to improve patients’ outcomes have been discussed. This study aims to evaluate the effect of division of the short gastric vessels (SGV) and the addition of a standardized fundophrenicopexia on the postoperative outcome after NF.

Methods

283 consecutive patients with GERD treated with NF were divided into four groups following consecutive time periods: with division of the SGV and without fundophrenicopexia (group A), with division of the SGV and with fundophrenicopexia (group B), without division of the SGV and with fundophrenicopexia (group C) and without division of the SGV and without fundophrenicopexia (group D). Postoperative contrast swallow, dysphagia scoring, GEDR-HRQL and proton pump inhibitor intake were evaluated. A comparative analysis of patients with division of the SGV and those without (161 A + B vs. 122 C + D), and patients with fundophrenicopexia and those without (78 A vs. 83 B and 49 C vs. 73 D) was performed.

Results

Fundophrenicopexia reduced postoperative dysphagia rates (0 group C vs. 5 group D, p = 0.021) in patients where the SGV were preserved and reoperation rates (1 group B vs. 7 group A, p = 0.017) in patients where the SGV were divided. There was no significant difference in the postoperative rates of heartburn relief, dysphagia, gas bloating syndrome, interventions, re-fundoplication and the GERD-HRQL score between groups A + B and C + D, respectively.

Conclusion

Standardized additional fundophrenicopexia in patients undergoing Nissen fundoplication significantly reduces postoperative dysphagia in patients without division of the SGV and reoperation rates in patients with division of the SGV. Division of the SGV has no influence on the postoperative outcome of NF.

Impact of chronic constipation on health-related quality of life and work productivity in Japan

BACKGROUND AND AIM

The impact of chronic constipation on health-related quality of life (HRQoL), work productivity, and healthcare resource use in Japan is not well understood. This study aimed to evaluate and compare the humanistic burden of respondents with chronic constipation to respondents without chronic constipation and to respondents with type 2 diabetes mellitus (T2DM), irritable bowel syndrome (IBS), and gastroesophageal reflux disease (GERD), respectively.

METHODS

This cross-sectional study collected demographic and general health data and HRQoL data as measured by the Short Form 12-Item (Version 2) Health Survey and EuroQol 5-dimension health surveys. Health impacts on employment-related activities and indirect costs were measured using the Work Productivity and Activity Impairment questionnaire. Propensity score matching was used to identify a control group without chronic constipation. Multivariate generalized linear models were used to identify potential factors that may impact the outcomes of respondents.

RESULTS

A total of 30 001 individuals responded to the Japan National Health and Wellness Survey 2017, whereof 3373 (11.2%) reported having chronic constipation; 963 were physician diagnosed. Compared with matched controls, patients with physician-diagnosed chronic constipation had lower mean HRQoL scores and higher mean absenteeism, presenteeism, total Work Productivity and Activity Impairment, and indirect costs. Physician-diagnosed chronic constipation was associated with a higher health burden than T2DM, IBS, and GERD.

CONCLUSIONS

Chronic constipation is associated with a considerable health burden, which is higher compared with T2DM, IBS, and GERD. These results suggest an urgent need for effective treatment of Japanese patients with chronic constipation to improve their quality of life.

Do patients with gastroesophageal reflux disease exhibit compromised bone quality prior to proton pump inhibitor therapy?

Patients with gastroesophageal reflux disease (GERD) are routinely treated with proton pump inhibitors (PPIs), despite many reports of increased fracture risk associated with PPI use. Notably, the skeletal properties in patients with GERD prior to PPI therapy have not been addressed. We hypothesized that PPI-naïve GERD patients have bone impairment, and that short-term treatment with PPI has minimal skeletal effects. To test this, 17 (12 men/5 women) GERD patients age 32–73 years, not previously exposed to PPI, and 17 age- and sex-matched controls were enrolled from September 2010 to December 2012. Bone mineral density (BMD) at lumbar spine, femoral neck, total hip, and trabecular bone score (TBS) at the lumbar spine, a marker of bone microarchitecture, were measured by dual X-ray absorptiometry. Markers of bone turnover and calcium homeostasis, and gastric hormones were analyzed. The same parameters were measured after three months of treatment with the PPI pantoprazole. The GERD patients displayed a significantly lower TBS at baseline than controls (1.31 ± 0.11 vs. 1.43 ± 0.07, p = 0.0006). Total hip and femoral neck BMD were lower in patients compared to controls, however, not significantly (p = 0.09 and 0.12, respectively). CTX was non-significantly higher in GERD patients at baseline (p = 0.11). After three months, changes in BMD, TBS and CTX did not differ between the groups. In conclusion, this is the first report demonstrating compromised bone quality and inferior BMD in PPI-naïve GERD patients. Treatment with pantoprazole did not influence bone parameters, indicating that short-term use with this PPI is safe for the skeleton.

•

Previous studies have reported an increased fracture risk in PPI users.

•

Patients with GERD had compromised bone quality before starting PPI.

•

Three months treatment with pantoprazole did not influence bone parameters.

Prevalence and risk factors for gastroesophageal reflux disease in the Indian population: A meta-analysis and meta-regression study

BACKGROUND

Indian population-based studies on the prevalence and risk factors for gastroesophageal reflux disease (GERD) are scanty, and a meta-analysis and a meta-regression of prevalence and risk factors based on the existing data have not yet been reported.

METHODS

A systematic review of all the available publications from India reporting data regarding prevalence and risk factors of GERD was performed. Heterogeneity was assessed using I² statistics. The meta-analysis was undertaken to measure the average proportion reported in the existing studies, and meta-regression models were used to explore the risk factors for it.

RESULTS

The nine studies included 20,614 subjects; the prevalence of GERD ranged from 5% to 28.5%. The summary effect size (weighted average proportion) estimated by meta-analytic model was 0.1415 (95% confidence interval [CI] 0.099 to 0.197). The results for the test of heterogeneity that included tau² (0.37, 95% CI 0.21 to 1.80), I² (98.9%, 95% CI 98.01 to 99.77), and the Q-statistic (707.670; p < 0.0001) suggested high heterogeneity in the effect sizes. The pooled proportion of GERD (random-effects model) was 15.573 (95% CI 11.046 to 20.714). In the meta-regression model, sample size (p = 0.005) explained about 50% of the heterogeneity.

CONCLUSION

The pooled prevalence of GERD in the Indian population is 15.6 (95% CI 11.046 to 20.714). The risk factors were age, body mass index (BMI), non-vegetarian diet, tea/coffee intake, tobacco, and alcohol consumption. However, there was significant heterogeneity in the studies.

Manifestations of ENT Caused By Gastroesophageal Reflux Disease

Introduction. The presence of gastric reflux in the pharynx and larynx causes reflux laryngopharyngitis. The incidence of laryngopharyngeal reflux has increased dramatically in recent years, but with the introduction of flexible fiber optic esophagoscopy, evidence-based research on gastroesophageal reflux disease has evolved greatly. Laryngoscopy is the main investigation to be performed to establish the diagnosis of reflux.

Material and methods. This study is both retrospective and prospective, the first being performed on a group of 175 patients, who presented in the ENT outpatient clinic, within the County Emergency Clinical Hospital “St. Andrew the Apostle” Constanta.

The aim of this paper is to evaluate and compare the manifestations of ENT caused by reflux disease but also to establish the correct therapeutic conduct.

Prevalence and risk factors of gastroesophageal reflux disease in a rural Indian population

BACKGROUND

Studies on frequency and risk factors of gastroesophageal reflux disease (GERD) in the rural Indian population are scanty.

METHODS

This household survey was undertaken by the trained interviewers in the adult population (≥ 18 years) in four villages in northern India using translated-validated Enhanced Asian Rome III and hospital anxiety and depression questionnaires.

RESULTS

Of 2774 subjects, 2019 (72.8%) had no heartburn. Heartburn frequency was as follows: 314 (11.3%) once/week, 143 (5.2%) twice/week, 85 (3.1%) thrice/week, 69 (2.5%) four times/week, 48 (1.7%) five times/week, 18 (0.6%) six times/week, 41 (1.5%) daily, 37 (1.4%) > once daily. A total of 298 (10.7%) had GERD (definition: heartburn > twice/week). Older age (36.5 vs. 35 years), non-Hindu religion (7, 2.4% vs. 30, 1.2%), lower education (127, 42.6% vs. 789, 31.9%), lower socioeconomic class (94, 31.5% vs. 517, 20.9%) and income (below Indian National Rupees [INR] 458; 105, 35.2% vs. 599, 24.2%), non-vegetarian diet (15, 5% vs. 105, 4.2%), intake of tea/coffee (260, 87.2% vs. 1687, 68.1%), carbonated soft drinks (216, 72.5% vs. 1234, 49.8%), and alcohol (48, 16.1% vs. 313, 12.6%), tobacco chewing (116, 38.9% vs. 681, 27.5%), and smoking (105, 35.2% vs. 672, 27.1%) were associated with GERD on univariate analysis. On multivariate analysis, body mass index > 25 kg/m² (odds ratio [OR] 1.23; 95% CI 0.88-1.71), predominant rice eating (1.13; 0.74-1.74), tobacco chewing and smoking (1.68; 1.24-2.30 and 1.36; 0.99-1.88), and alcohol (1.2; 0.78-1.83) and carbonated soft drinks (2.48; 1.79-3.44) intake were associated with GERD. A total of 122 (41%) had associated functional dyspepsia. Psychological comorbidities were commoner among those with than without GERD.

CONCLUSION

In this rural Indian population, 10.7% had GERD and predominant rice eating, tobacco chewing, and carbonated soft drink intake were the risk factors. Psychological comorbidities were common.

Epidemiology and Outcomes of Young-Onset Esophageal Adenocarcinoma: An Analysis from a Population-Based Database

BACKGROUND

Esophageal adenocarcinoma is a lethal cancer with rising incidence. There are limited data in younger (<50 years) patients with esophageal adenocarcinoma. We aimed to assess time trends in the incidence and outcomes of "young-onset" esophageal adenocarcinoma using a population-based database.

METHODS

We queried the Surveillance, Epidemiology, and End Results 9 database to identify patients with esophageal adenocarcinoma between 1975 and 2015. Patients were stratified into three age strata: <50, 50 to 69, and ≥70 years. Staging was stratified as localized, regional, and distant. Trends in incidence, disease stage, and survival were assessed in three periods (1975-89, 1990-99, and 2000-2015). Univariate and multivariate models were created to identify predictors of mortality.

RESULTS

Esophageal adenocarcinoma incidence has increased in patients <50 years of age, with an annual percentage change of 2.9% (95% confidence interval, 1.4%-4.4%) from 1975 to 2015. Young-onset esophageal adenocarcinoma presented at more advanced stages (regional + distant) compared with older patients (84.9% vs. 67.3%; P < 0.01), with increasing proportion of advanced stages over the study period. These patients also experienced poorer 5-year esophageal adenocarcinoma-free survival compared with older patients (22.9%% vs. 29.6%; P < 0.01), although this finding was attenuated on stage-stratified analysis.

CONCLUSIONS

Young-onset esophageal adenocarcinoma, while uncommon, is rising in incidence. Concerningly, the proportion of advanced disease continues to increase. Young-onset esophageal adenocarcinoma also presents at more advanced stages, resulting in poorer esophageal adenocarcinoma-free survival.

IMPACT

Patients with esophageal adenocarcinoma younger than 50 years present at more advanced stages with higher esophageal adenocarcinoma-specific mortality compared with older peers. Current diagnostic and management strategies for young-onset esophageal adenocarcinoma may need to be reevaluated.

The Natural Course of Gastroesophageal Reflux Disease: A Critical Appraisal of the Literature

Interpreting natural course studies have been very difficult due to their retrospective design, lack of standardization, reliability of reported mucosal findings, liberal use of antireflux medications and accuracy of chart documentation. Studies provided a wide range of progression rates of patients from nonerosive reflux disease (NERD) to erosive esophagitis (EE). However, direct progression from NERD to Barrett's esophagus appears to be an uncommon phenomenon. Importantly, progression of NERD patients was commonly reported to low grades of EE, which are currently considered inconclusive of gastroesophageal reflux disease. Reports of progression rates from low grades to high grades EE also vary considerably. Progression of patients with EE, without metaplastic epithelium underneath the inflammation, to Barrett's esophagus is relatively uncommon. Recently, it was also recognized that regression from high grades to low grades EE and from EE to NERD is a common phenomenon affecting up to 25% of the patients from each group.

Findings from a novel scintigraphic gastroesophageal reflux study in asymptomatic volunteers

Gastroesophageal reflux disease (GERD) is a common and growing problem in most western countries. It may present with the typical symptoms of heartburn and regurgitation or with the effects of extra-esophageal disease. We have developed and validated a scintigraphic test that evaluates reflux at both sites in patients at high risk of laryngopharyngeal reflux and lung aspiration. We hypothesized that the test may be able to separate physiologic reflux from pathological reflux and examined this possibility in normal asymptomatic volunteers. Asymptomatic volunteers were screened with the Belafsky reflux symptom index (RSI) and entered into the trial if scores were less than 13. ^99mTc Phytate was ingested orally and dynamic studies from the pharynx to the stomach were obtained while upright and supine. A delayed study of the thorax was also obtained for lung aspiration of refluxate. Studies were semi-quantitated graphically as time-activity curves. A total of 25 volunteers were studied (13 M, 12 F) with a mean age of 57.5 yr (Range 40-85 yr). None gave a history of heartburn or regurgitation. Mean RSI was 4.1 (range 0-10). Testing showed upright gastroesophageal reflux to the mid-upper esophagus without pharyngeal contamination in 32%. None of the subjects showed supine reflux or lung aspiration. This result corresponds well with intraluminal impedance/pH monitoring in normal volunteers. The scintigraphic reflux test gives similar results to standard intraluminal impedance/pH studies in normal volunteers. A significant proportion of asymptomatic volunteers demonstrate upright reflux only.

A transformational change in scintigraphic gastroesophageal reflux studies: A comparison with historic techniques

BACKGROUND

The inclusion of scintigraphy in the diagnostic algorithm for gastroesophageal reflux is controversial due to variability in methodology and reporting. A novel scintigraphic reflux study has been developed and validated against the current standards for the diagnosis of gastroesophageal reflux disease (GORD).

OBJECTIVE

To compare a new scintigraphic reflux test against historic techniques and standardised diagnostic reference tests for gastroesophageal reflux disease.

METHODS

Paired scintigraphic studies were conducted in seventeen patients. All patients underwent at least one other standardised diagnostic reflux test such as 24- hour oesophageal impedance/ pH, and oesophageal manometry, barium swallow, gastroscopy or the Peptest. Patients inadvertently presented at sites B for scintigraphic reflux testing rather than at Site A which was part of an approved study. The findings from sites B did not correlate with clinical symptoms and other diagnostic reference tests from GORD. These studies were then repeated at Site A with approval from the patients. A second reflux study was performed at site A, utilising a novel technique with the capability of assessing oesophageal and extra-oesophageal disease.

RESULTS

The Site A technique shows good concordance with the reference diagnostic tests with an accuracy of 82.4% and kappa of 0.64 (SE: 0.16, p = 0.00). Site B had an overall accuracy of 47.1% and kappa of 0.066 (SE: 0.068, p = 0.45).

CONCLUSION

The Site A technique shows higher accuracy than either site B or the historic reflux techniques. It has characteristics that make it an effective screening tool for assessment of local oesophageal disease and its extraoesophageal manifestations.

Advances in the diagnosis and management of gastroesophageal reflux disease

Gastroesophageal reflux disease (GERD) is a multifaceted disorder encompassing a family of syndromes attributable to, or exacerbated by, gastroesophageal reflux that impart morbidity, mainly through troublesome symptoms. Major GERD phenotypes are non-erosive reflux disease, GERD hypersensitivity, low or high grade esophagitis, Barrett's esophagus, reflux chest pain, laryngopharyngeal reflux, and regurgitation dominant reflux. GERD is common throughout the world, and its epidemiology is linked to the Western lifestyle, obesity, and the demise of Helicobacter pylori. Because of its prevalence and chronicity, GERD is a substantial economic burden measured in physician visits, diagnostics, cancer surveillance protocols, and therapeutics. An individual with typical symptoms has a fivefold risk of developing esophageal adenocarcinoma, but mortality from GERD is otherwise rare. The principles of management are to provide symptomatic relief and to minimize potential health risks through some combination of lifestyle modifications, diagnostic testing, pharmaceuticals (mainly to suppress or counteract gastric acid secretion), and surgery. However, it is usually a chronic recurring condition and management needs to be personalized to each case. While escalating proton pump inhibitor therapy may be pertinent to healing high grade esophagitis, its applicability to other GERD phenotypes wherein the modulating effects of anxiety, motility, hypersensitivity, and non-esophageal factors may dominate is highly questionable.

Treatment of Dyspepsia, Heartburn, and Related Symptoms with Gastricumeel Compared to Proton Pump Inhibitors: A Prospective Reference-Controlled Observational Study

BACKGROUND

Dyspepsia and heartburn are extremely common conditions, thus a search for safe and effective treatment alternatives is justified.

OBJECTIVES

To demonstrate the noninferiority of Gastricumeel (Ga6) in terms of effectiveness and safety to proton pump inhibitors (PPIs) in the treatment of patients with dyspepsia and/or heartburn.

METHODS

Prospective, comparative, observational cohort study. Patients with dyspepsia or heartburn were treated either with Ga6 or with PPIs as monotherapy during approximately 6 weeks. The intensity of eight symptoms was assessed as well as overall condition, treatment compliance and tolerability, and any adverse drug reactions. Adjustment for covariates was done via the calculation of propensity scores in logistic regression.

RESULTS

A total of 640 patients (447 Ga6, 193 PPIs) from 48 German general practices participated. More than half the patients had suspected acute gastritis and around 40% of patients had heartburn. Adjusted between-treatment difference scores of changes in the intensity of the eight assessed symptoms were within the bounds for noninferiority of Ga6 compared to PPIs. Effectiveness ratings were comparable; compliance and tolerability were rated better in the Ga6 group.

CONCLUSION

It is worth considering Ga6 as a safe and effective treatment option in the management of dyspepsia and heartburn.

[Food patterns in Russian patients with gastroesophageal reflux disease: the results of pilot comparative study]

AIM

To evaluate nutritional patterns in patients with gastroesophageal reflux disease (GERD) compared to the control group without GERD.

MATERIALS AND METHODS

The data of complex examination of patients referred to perform esophageal pH-impedance recording and who gave written informed consent to participate in the study served as a source data. All the participants underwent complex examination, including clinical data (presence of heartburn and acid regurgitation), symptom evaluation (GERD-Q questionnaire), esophagogastroscopy, esophageal pH-impedance recordings and food frequency questionnaire. Diagnosis of GERD was based on GERD-Q score 8, acid exposure time 6%, number of gastroesophageal refluxes 80/day by 24-hrs esophageal pH-impedance recordings. Nutritional patterns were assessed with the use of healthy eating pyramid principles.

RESULTS

Overall 165 patients were enrolled and the data of 150 of them (34 with confirmed GERD and 116 of the control group) were available for the final analysis. The patients of the both groups consumed lower compared to the recommended amounts of dairy and higher amounts of meat. Those with GERD consumed larger amounts of fruits (0.910.68 compared to the values of healthy eating pyramid vs 0.520.57 in the control group, p=0.001), and fats (0.690.55 vs 0.490.55, p=0.001). Compared to the controls, patients with GERD consumed lower amounts of vegetables (0.860.46 of the healthy eating pyramid vs 0.940.63 in the control group, р=0.004) and sugars confectionaries (0.380.39 vs 1.930.98, p=0.0001).

CONCLUSION

Nutritional patterns of patients with gastroesophageal reflux disease significantly differ compared to the control group. The obtained data may be used for diet modification in patients with arterial hypertension.

Magnetic sphincter augmentation versus fundoplication for gastroesophageal reflux disease: pros and cons

PURPOSE OF REVIEW

The purpose of this magnetic sphincter augmentation (MSA) year in review article is to provide a clear understanding for the current state of MSA literature in 2019, and contrast MSA outcomes with traditional fundoplication.

RECENT FINDINGS

Continued work was performed in 2019 to expand patient populations eligible for MSA including those with hiatal hernia, post-bariatric patients, patients necessitating a thoracic approach, and patients with esophageal intestinal metaplasia. Additionally, a large systematic review reinforced earlier findings comparing laparoscopic fundoplication to MSA. This study demonstrated equivalency over many different operative outcomes, with MSA patients having less bloating while also retaining the ability to belch and vomit. Furthermore, independent research teams found a modest cost savings for MSA over laparoscopic fundoplication with budget analysis.

SUMMARY

MSA is a safe and efficacious procedure originally approved for patients with medically refractory, uncomplicated gastroesophageal reflux disease. The accumulating body of evidence suggests patients with intestinal metaplasia or hiatal hernias can safely and effectively undergo MSA, whereas further research will be required before MSA is widely used for post-bariatric patients or for patients requiring a transthoracic surgical approach. MSA is equivalent or superior to laparoscopic fundoplication in all surgical outcomes measured thus far.

Sugar Codes Conjugated Alginate: An Innovative Platform to Make a Strategic Breakthrough in Simultaneous Prophylaxis of GERD and Helicobacter pylori Infection

INTRODUCTION

Currently, gastroesophageal reflux disease (GERD) is one of the most ubiquitous problems in clinical practice. An antacid-alginate combination (under the trade name Gaviscon) is a natural-based product that effectively suppresses GERD. This product acts via the formation of viscous gel that floats on the top of the gastric content. On the other hand, efficient management of Helicobacter pylori infection with minimal side effects is an important goal for gastroenterologists. Furthermore, some H. pylori-positive patients suffer from GERD.

METHODS

Here, we present the results of investigations on alginate conjugated to sugar codes in order to find initial clues regarding the potential ability of this conjugate in the simultaneous prophylaxis of GERD and H. pylori infection in an in vitro assay.

RESULTS

It is noteworthy that our results reveal that sugar codes conjugated alginate considerably decrease (approximately 74%) the adhesion of H. pylori to gastric epithelial cells in vitro. Moreover, surprisingly after conjugation of sugar codes, alginate can maintain its ability to create gel. Our results demonstrate that alginate conjugated to sugar codes is not cytotoxic.

CONCLUSION

The preparation of these conjugates can be regarded as the first step to establish a new roadmap for the simultaneous prevention of GERD and H. pylori infection in future studies on in vivo models.

Physicians' adherence to management guidelines for H. pylori infection and gastroesophageal reflux disease: a cross-sectional study

BACKGROUND

Primary care physicians (PCPs) play a pivotal role in the management of illnesses of the digestive tract. The study aim was to assess the adherence of PCPs to the guidelines on the management of Helicobacter pylori (H. pylori) infection and gastroesophageal reflux disease (GERD) in adults.

METHODS

We conducted a cross-sectional study during March-July 2017 using the survey platform of Maccabi Healthcare Services in Israel. The study questionnaire assessed adherence to the Maastricht/Florence guidelines on H. pylori infection and the American College of Gastroenterology guidelines on the management of GERD. We sent the study questionnaires to a random sample of 610 PCPs via electronic mails. We contacted those who did not respond by telephone; eventually 180 physicians completed the survey.

RESULTS

Ninety (50%) and 60 (36%) of the responders reported using professional guidelines for the diagnosis and management of H. pylori infection and GERD, respectively. Of the 180 participants, 153 (85%) reported referring patients with suspected peptic ulcer disease to H. pylori testing, 109 (61%) reported referring patients with unexplained iron deficiency anemia and 83 (46%) refer relatives of gastric cancer patients. In caring for young patients who have dyspepsia without alarm symptoms, 127 (74%) reported referral to a urea breath test for the diagnosis of H. pylori infection, and 136 (81%) referral to a specialist in gastroenterology if alarm symptoms present. Triple therapy with proton pump inhibitors/clarithromycin/amoxicillin or metronidazole was reported as first-line therapy by 141 (83%) participants. For GERD, 94-98% of the participants followed the appropriate recommendations.

CONCLUSIONS

We identified gaps between the practices of PCPs and the guidelines on H. pylori infection management, while guidelines on GERD management are well adopted. Simplification of the guidelines and exploring barriers towards their implementation by PCPs is warranted.

Gastroesophageal reflux disease in a typical African population: a symptom-based multicenter study

BACKGROUND

The prevalence of gastroesophageal reflux disease (GERD) in Africa is not known but is believed to be increasing because of demographic and epidemiologic transition. The main objectives of this study were to determine the prevalence and risk factors of GERD, and its degree of overlap with dyspepsia and irritable bowel syndrome (IBS) in Nigeria, a typical African population.

METHODS

This was an observational, cross-sectional and descriptive study of adult Nigerians. Diagnosis of GERD was by means of the gastroesophageal reflux disease questionnaire (GERDQ) while the diagnosis of dyspepsia and IBS was based on the Rome III criteria for the diagnosis of functional gastrointestinal disorders. The GERDQ and Rome III questionnaires for dyspepsia and IBS were merged into a composite questionnaire and administered to the study participants who were recruited with a multi-stage sampling technique.

RESULTS

Out of 3520 subjects who participated in the study across the country, 269 (7.6%) satisfied the diagnostic criteria for GERD, while 107 (3.0%) had GERD associated with significant impairment of quality of life. Risk factors of GERD (represented by odds ratios) were age 1.014(95% CI: 1.006-1.022), use of analgesics 1.461 (95% CI: 1.060-2.025), and use of herbs 1.318 (95% CI: 1.020-1.704). Overlap of GERD with dyspepsia and/or IBS was observed in over 50% of cases.

CONCLUSIONS

The prevalence of GERD in this study is 7.6%. Age, use of analgesics and use of herbs increase the risk, albeit minimally. A high degree of overlap with dyspepsia and IBS exists in Nigerian patients with GERD.

Treatment of Refractory Gastroesophageal Reflux Disease

Gastroesophageal reflux disease (GERD) is a common disorder that is treated with lifestyle modification, weight loss, and medications, such as proton pump inhibitors (PPIs). An empiric course of PPI therapy is an effective and cost-effective strategy for the management of GERD. However, in some patients, PPI therapy and lifestyle changes are inadequate to control symptoms. When there is persistence of symptoms despite empiric therapy, patients are labeled as having refractory GERD. This label underestimates the wide differential diagnosis of foregut pathology that can mimic symptoms of GERD. A careful history of symptoms, response to PPI therapy, adherence, compliance, and timing helps elucidate if medication has been helping. When patients are refractory, alternative etiologies of GERD must be considered. Many of these alternatives can be determined on an upper endoscopy or with complementary testing, such as high-resolution esophageal manometry or gastric emptying testing as symptoms dictate. When an alternative cause is not found and index endoscopy is normal, additional testing with either traditional pH or impedance testing can be completed based on prior examination results and response to therapy. Further therapy, including medical, endoscopic, or surgical, can then be targeted at the etiology.

Magnetic Sphincter Augmentation for Gastroesophageal Reflux Disease

Magnetic sphincter augmentation is an effective and safe surgical method for the treatment of gastroesophageal reflux disease (GERD). The device has been compared with twice-daily proton pump inhibitor therapy and laparoscopic fundoplication (in randomized trials and prospective cohort studies, respectively). Magnetic sphincter augmentation was superior to medical therapy and equivalent to surgery for the relief of GERD symptoms. Recent research focuses on implanting the device into more complex patients, such as those with larger hiatal hernias or those with Barrett's esophagus. Additional novel research topics include cost analysis and predicting and minimizing postoperative dysphagia.

Application of mineral waters in the complex treatment of patients with gastroesophageal reflux disease

BACKGROUND

Gastroesophageal reflux disease (GERD) is one of the most common gastric pathologies. Recently, there has been a growing interest in the healing effects of mineral waters (MW).

METHODS

Ninety patients with GERD were under observation. The study used the following methods: anamnestic, clinical, studies of biochemical blood parameters, ultrasonographic studies of the digestive system, fibroesophagogastroduodenoscopy with intragastric pH-metric. After preliminary research, all patients were randomly divided into three groups of 30 people. The control group (group 1) who were prescribed a basic treatment complex-dietary and proton pump inhibitor group drugs. Patients of group 2 in addition to the standard course of treatment received boric highly mineralized bicarbonate sodium water. Patients of group 3 in addition to the basic therapy were prescribed an internal course treatment of highly mineralized sulfate-bicarbonate sodium-magnesium water.

RESULTS

The use of the basic complex of treatment for a month in control group did not lead to a significant leveling of signs of dyspeptic and asthenic syndromes. The use of boron highly mineralized sodium bicarbonate water led to a significant leveling of signs of abdominal pain and dyspeptic syndromes, improvement of acid-forming function of the stomach, but no reliable dynamics were observed in eliminating signs of cytolytic, mesenchymal inflammatory and cholestatic syndromes. Application of highly mineralized sulfate-hydrocarbonate sodium magnesium water improves the elimination of dyspepsia and pain syndromes, normalization of the functional state of the liver.

CONCLUSIONS

The obtained data confirm the prospects of using highly mineralized mineral waters in the complex treatment of GERD patients.

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

OBJECTIVE

Heartburn and regurgitation are the most common gastroesophageal reflux symptoms, and dysphagia could be a possible symptom. This investigation aimed to evaluate the prevalence of non-obstructive dysphagia in patients with heartburn and regurgitation.

METHODS

A total of 147 patients (age, 20-70 years; women, 72%) complaining of heartburn and regurgitation, without esophageal stricture, previous esophageal surgery, or other diseases, were evaluated. Twenty-seven patients had esophagitis. The Eating Assessment Tool (EAT-10) was employed to screen for dysphagia; EAT-10 is composed of 10 items, and the patients rate each item from 0 to 4 (0, no problems; 4, most severe symptom). Results of the 147 patients were compared with those of 417 healthy volunteers (women, 62%; control group) aged 20-68 years.

RESULTS

In the control group, only two (0.5%) had an EAT-10 score ≥5, which was chosen as the threshold to define dysphagia. EAT-10 scores ≥5 were found in 71 (48.3%) patients and in 55% of the patients with esophagitis and 47% of the patients without esophagitis. This finding indicates a relatively higher prevalence of perceived dysphagia in patients with heartburn and regurgitation and in patients with esophagitis. We also found a positive correlation between EAT-10 scores and the severity of gastroesophageal reflux symptoms based on the Velanovich scale.

CONCLUSION

In patients with heartburn and regurgitation symptoms, the prevalence of dysphagia was at least 48%, and has a positive correlation with the overall symptoms of gastroesophageal reflux.

Risks of Sulpiride-Induced Parkinsonism in Peptic Ulcer and Gastroesophageal Reflux Disease Patients in Taiwan: A Nationwide Population-Based Study

BACKGROUND

Sulpiride is a highly selective dopamine D2 receptor antagonist and is commonly used in psychiatric disorders, Tourette syndrome, peptic ulcer disease (PUD), and gastroesophageal reflux disease (GERD). However, sulpiride has been recognized as a potential cause of drug-induced parkinsonism (DIP) for a long time. In this study, we aimed to focus on analysis of sulpiride-induced parkinsonism (SIP) in PUD and GERD patients based on a nationwide population.

METHODS

Data were obtained from the Taiwan's National Health Insurance Research Database. The study enrolled 5,275 PUD or GERD patients, of whom were divided into two groups, based on their exposure (1,055 cases) or non-exposure (4,220 cases) to sulpiride.

RESULTS

During the study period (2000-2012), the incidence rate of parkinsonism was 261.5 and 762.2 per 100,000 person-years in the control and sulpiride-treated groups, respectively. For patients with at least 14 days of prescription for sulpiride, the adjusted hazard ratio (aHR) was 2.89, 95% confidence interval (CI): 2.04-4.11. Patients with age more than 65 years (aHR = 4.99, 95% CI = 2.58-9.65), hypertension (aHR = 2.39, 95% CI = 1.49-3.82), depression (aHR = 2.00, 95% CI = 1.38-2.91), and anxiety (aHR = 1.45, 95% CI = 1.01-2.09) had significant higher risk of developing parkinsonism. An average annual cumulative sulpiride dose > 1,103 mg was accompanied by the greatest risk of SIP; sulpiride use for ≥ 9 days is a cut-off point for predicting future SIP.

CONCLUSION

At the population level, sulpiride may be frequently prescribed and apparently effective for PUD and GERD. SIP is associated with older age, hypertension, depression or anxiety comorbidities. Physicians should be aware of the neurogenic adverse effects, even when the drug is only used in low-dose or a short duration.

Intra-Esophageal pH Monitoring on Two Consecutive Days in Patients With Gastroesophageal Reflux Symptoms

Background

The best method to measure the frequency and duration of gastroesophageal reflux is 24-h pH or 24-h pH/impedance monitoring. However, the detection of reflux can vary when measured on different days. Our aim was to evaluate the possibility that the severity of gastroesophageal reflux is different even under similar conditions on two consecutive days.

Methods

We performed a 48-h pH monitoring in 12 subjects, aged 25 - 63 years, who complaint of heartburn and regurgitation, ten with esophagitis and two with non-erosive disease. The pH measurement was conducted at 5 cm from the lower esophageal sphincter. The patients stayed at the Clinical Investigation Ward of the hospital for 48 h. On each day, they consumed a 2,000 calorie diet. The results obtained on the first day were compared with those on the second day.

Results

Mean reflux index in the upright position was different between the two days. Results of the pH-monitoring within the 2 h after the meal revealed differences in the number of acidic reflux and reflux index episodes. Three patients had abnormal DeMeester score on one day and normal score on the other day. Considering the upper limit of 6.0% of the test duration with esophageal pH < 4 as indicative of gastroesophageal reflux disease, two patients showed abnormal results on one day and normal results on the other day.

Conclusions

The 24-h pH monitoring, performed on two consecutive days under similar conditions, can lead to different diagnosis of gastroesophageal reflux disease in symptomatic patients.

Impact of Chronic Statins Use on the Development of Esophagitis in Patients with Gastroesophageal Reflux Disease

BACKGROUND AND AIMS

We aimed to assess whether chronic statins used (> 6 months) were protective of the development of esophagitis in patients with gastroesophageal reflux disease. In the presence of esophagitis, complications such as strictures, Barrett's esophagus, and adenocarcinoma were the most common. Statins, lipid lowering drugs with a pleiotropic effect, are recently implicated in various pathologies. Nevertheless, the possible impact of statins in esophagitis development has never been assessed.

METHODS

We performed a retrospective, cross-sectional, single center study that included 4148 gastroesophageal reflux disease patients from 2014 and 2018 at EMMS Nazareth Hospital. We divided the patients into 5 groups. The groups were split into positive control group, which was the nonesophagitis group, and the other 4 groups were A-D (as per Los Angeles classification).

RESULTS

Overall, out of the 4148 patients included, 48% were males and 2840 patients were in the control group. In groups A, B, C, and D there were 818, 402, 72, and 16 patients, respectively. Logistic regression analysis revealed that chronic statins usage is protective by preventing development esophagitis (OR 0.463 [95%CI 0.370-0.579], p < 0.0001). NSAIDS use, Hiatus hernia, and H. pylori were promoting factors (OR, 1.362, 1.779, and 1.811; 95% CI, 1.183-1.569, 1.551-2.040, and 1.428-2.298; P<0.0001, P<0.0001, and P<0.0001, respectively).

CONCLUSION

Using chronic statins was protective to the development of esophagitis among GERD patients. Our findings of potential clinical application mandate further randomized controlled trials to better assess the impact of statins on esophagitis.
