Abstract
Proton pump inhibitors (PPIs) have been available for over three decades and are among the most commonly prescribed medications. They are effective in treating a variety of gastric acid-related disorders. They are freely available and based on current evidence, use of PPIs for inappropriate indications and duration appears to be common. Over the years, concerns have been raised on the safety of PPIs as they have been associated with several adverse effects. Hence, there is a need for PPI stewardship to promote the use of PPIs for appropriate indication and duration. With this objective, the Indian Society of Gastroenterology has formulated guidelines on the rational use of PPIs. The guidelines were developed using a modified Delphi process. This paper presents these guidelines in detail, including the statements, review of literature, level of evidence and recommendations. This would help the clinicians in optimizing the use of PPIs in their practice and promote PPI stewardship.

Abstract
Sleeve gastrectomy (SG) is the most frequently performed bariatric surgical intervention worldwide. Gastroesophageal reflux disease (GERD) is frequently observed after SG and is a relevant clinical problem. This prospective study investigated the gastroesophageal junction (GEJ) and pyloric sphincter by impedance planimetry (EndoFlipTM) and their association with GERD at a tertiary university hospital center. Between January and December 2018, patients undergoing routine laparoscopic SG had pre-, intra-, and postoperative assessments of the GEJ and pyloric sphincter by EndoFlipTM. The distensibility index (DI) was measured at different volumes and correlated with GERD (in accordance with the Lyon consensus guidelines). Nine patients were included (median age 48 years, preoperative BMI 45.1 kg/m2, 55.6% female). GERD (de novo or stable) was observed in 44.4% of patients one year postoperatively. At a 40-ml filling volume, DI increased significantly pre- vs. post-SG of the GEJ (1.4 mm2/mmHg [IQR 1.1-2.6] vs. 2.9 mm2/mmHg [2.6-5.3], p VALUE=0.046) and of the pylorus (6.0 mm2/mmHg [4.1-10.7] vs. 13.1 mm2/mmHg [7.6-19.2], p VALUE=0.046). Patients with postoperative de novo or stable GERD had a significantly increased preoperative DI at 40 ml of the GEJ (2.6 mm2/mmHg [1.9-3.5] vs. 0.5 mm2/mmHg [0.5-1.1], p VALUE=0.031). There was no significant difference in DI at 40 mL filling in the preoperative pylorus and postoperative GEJ or pylorus. In this prospective study, the DI of the GEJ and the pylorus significantly increased after SG. Postoperative GERD was associated with a significantly higher preoperative DI of the GEJ but not of the pylorus.

Nocturnal acid breakthrough and esophageal acidification during treatment with dexlansoprazole as compared to omeprazole in patients with gastroesophageal reflux disease. Indian J Gastroenterol 2022; 41:405-414. [PMID: 35771390 DOI: 10.1007/s12664-022-01270-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/14/2022] [Accepted: 06/02/2022] [Indexed: 02/04/2023]
Abstract
BACKGROUND Nocturnal acid breakthrough (NAB) may differ based on duration of proton pump inhibitor (PPI) action and Helicobacter pylori (H. pylori) infection; NAB may influence esophageal acidification (EA) and mucosal damage. Dexlansoprazole, a long-acting PPI, was not compared with omeprazole for NAB, gastric acid suppression, and EA in relation to H. pylori infection. METHODS In this prospective open-label comparative observational study, gastroesophageal reflux disease (GERD) patients were evaluated using 24-h dual-channel pH-impedance monitoring while on dexlansoprazole (60 mg, n = 39) and omeprazole (20 mg, n = 41) to study the degree of gastric acid suppression, esophageal acid exposure, and NAB (primary outcome measures). H. pylori was detected by rapid urease test and histology. RESULTS NAB tended to be frequent with omeprazole than dexlansoprazole (33/41 [80.5%] vs. 23/39 [59%]; p = 0.06). Though nocturnal mean esophageal pH was comparable between the dexlansoprazole and omeprazole groups, its duration was less with the former (181.5 [15.2-334.2] vs. 283 [158-366] min, p = 0.03). NAB was as frequent in the H. pylori-infected than the non-infected group (11/19 [57.9%] vs. 45/61 [73.8%]; p = 0.1). The nocturnal gastric and esophageal pH in the H. pylori-infected group was higher than in the non-infected group (4.6 ± 1.7 vs. 4 ± 1.6, p = 0.157; 6.1 ± 0.6 vs. 5.8 ± 0.6, p = 0.128). Dexlansoprazole tended to increase 24-h and nocturnal mean gastric pH among H. pylori-infected more than omeprazole (5.9 ± 1.1 vs. 4.2 ± 1.7, p = 0.023; 5.7 ± 1.2 vs. 3.8 ± 1.5, p = 0.006). CONCLUSION Dexlansoprazole is more effective than omeprazole in suppressing gastric acid secretion, resulting in lesser EA and NAB, particularly in the presence of H. pylori.

Abstract
Heartburn and acid regurgitation are the typical symptoms of gastroesophageal reflux. Despite the availability of several treatment options, antacids remain the mainstay treatment for gastroesophageal reflux-related symptoms based on their efficacy, safety, and over-the-counter availability. Antacids are generally recommended for adults and children at least 12 years old, and the FDA recommends antacids as the first-line treatment for heartburn in pregnancy. This narrative review summarizes the mechanism, features, and limitations related to different antacid ingredients and techniques available to study the acid neutralization and buffering capacity of antacid formulations. Using supporting clinical evidence for different antacid ingredients, it also discusses the importance of antacids as OTC medicines and first-line therapies for heartburn, particularly in the era of the COVID-19 pandemic, in which reliance on self-care has increased. The review will also assist pharmacists and other healthcare professionals in helping individuals with heartburn to make informed self-care decisions and educating them to ensure that antacids are used in an optimal, safe, and effective manner.

Abstract
AbstractBarrett's esophagus (BE) denotes the replacement of stratified squamous epithelium of esophagus by columnar epithelium. It is associated with a significantly increased risk of esophageal adenocarcinoma and hence patients with BE are advised endoscopic surveillance for early detection of dysplastic and neoplastic lesions. Esophageal cancer is the sixth most common cancer in terms of incidence and mortality in India. Around 15 to 25% of esophageal cancers are adenocarcinoma. BE is likely to be an important precursor of esophageal adenocarcinoma and we may be missing patients with BE in our busy endoscopy practice. The detection of BE may be improved by identifying high-risk groups, performing thorough endoscopic examination, and applying newer imaging techniques. The high-risk group includes patients with chronic gastroesophageal reflux disease, obesity, smoking, etc. During endoscopic examination, a careful assessment of the gastroesophageal junction and identification of important landmarks such as gastroesophageal junction and Z line are essential to detect BE. Management of BE depends on the detection of dysplasia and for this four quadrant mucosal biopsy is recommended every 1 to 2 cm. However, random biopsy samples only a small area of mucosa and advanced technologies for real-time detection of dysplasia and neoplasia may overcome this limitation. In this review, we discuss the current scenario of BE in India and ways to improve the detection of BE including dysplastic lesions.

Abstract
BACKGROUND Acute liver failure caused by the ingestion of yellow phosphorus-containing rodenticide has been increasing in incidence over the last decade and is a common indication for emergency liver transplantation in Southern and Western India and other countries. Clear guidelines for its management are necessary, given its unpredictable course, potential for rapid deterioration and variation in clinical practice. METHODS A modified Delphi approach was used for developing consensus guidelines under the aegis of the Liver Transplantation Society of India. A detailed review of the published literature was performed. Recommendations for three areas of clinical practice, assessment and initial management, intensive care unit (ICU) management and liver transplantation, were developed. RESULTS The expert panel consisted of 16 clinicians, 3 nonclinical specialists and 5 senior advisory members from 11 centres. Thirty-one recommendations with regard to criteria for hospital admission and discharge, role of medical therapies, ICU management, evidence for extracorporeal therapies such as renal replacement therapy and therapeutic plasma exchange, early predictors of need for liver transplantation and perioperative care were developed based on published evidence and combined clinical experience. CONCLUSION Development of these guidelines should help standardise care for patients with yellow phosphorus poisoning and identify areas for collaborative research.

Abstract
INTRODUCTION Functional dyspepsia (FD), although commoner than organic dyspepsia (OD) in-hospital studies, community data, particularly from rural areas, are lacking. We performed a rural community study in Bangladesh with the primary aims to evaluate (i) the prevalence of uninvestigated dyspepsia (UD), FD, and OD and (ii) the risk factors for UD. METHODS This house-to-house survey was performed using a translated-validated enhanced Asian Rome III questionnaire and endoscopy with Helicobacter pylori tests, including genotyping. RESULTS Of 3,351/3,559 responders ([94.15%], age 40.41 ± 16.05 years, female 1924 [57.4%]), 547 (16.3%) had UD (female 346 [18%] vs male 201 [14%]; P = 0.002); 201 (6%), 88 (2.6%), and 258 (7.7%) had postprandial distress (PDS), epigastric pain syndromes (EPS) and PDS-EPS overlap, respectively. On multivariate analysis, age >50 years (adjusted odds ratio [AOR] 1.34 [1.07-1.68]), female sex (AOR 1.42 [1.17-1.74]), being married (AOR 1.57 [1.21-2.07]), lower family income (AOR 1.79 [1.43-2.26]), nonsteroidal anti-inflammatory drug use (AOR 7.05 [2.11-23.55]), previous acute gastroenteritis (AOR 5.42 [1.83-16]), and psychological distress (AOR 5.02 [2.87-8.76]) were risk factors for UD. Of 346/547 (63.25%) undergoing endoscopy, 232 (67.05%) and 114 (32.95%) had FD and OD (peptic ulcers [PU] 99 [28.61%] and erosive esophagitis 13 [3.76%]). About 53% of FD subjects had EPS-PDS overlap, 32% had PDS, and only 15% had EPS. H. pylori was detected in 266/342 (78%) dyspeptics (FD 173/230 [75.2%], vs OD 92/114 [82.1%], P = 0.169). DISCUSSION Sixteen percent, 11% and 5% of rural Bangladeshi Asian adults had UD, FD, and PU, respectively. One-third of UD subjects had OD, mostly PU.JOURNAL/cltg/04.03/01720094-202104000-00016/inline-graphic1/v/2021-04-15T161418Z/r/image-tiff.

Abstract
BACKGROUND Esophageal acid exposure time (AET) during 24 h pH monitoring is reproducible and predictive outcomes of treatment for gastroesophageal reflux disease. Several small Asian studies have investigated the normal range of the AET; the range may be different from that in Western populations. We evaluated its normal range in healthy Asian compared to Western subjects. METHODS We searched PubMed, Embase, Cochrane Library, and KoreaMed for studies that reported pH monitoring parameters in healthy subjects. Studies that reported the AET values of healthy subjects were eligible for the analyses. The upper limit of normal of the AET was obtained from the 95th percentile of the available raw data or calculated as the mean value +2 standard deviations. KEY RESULTS Nineteen Asian and 49 Western studies were assessed. The estimated AET values were analyzed using a bootstrapping technique, weighted according to the sample size. The mean AET was 1.1% and 2.9% in the Asian and Western populations, respectively. The upper limit of the reference range was 3.2% (95% confidence interval [CI], 2.7-3.9%) and 8.2 (95% CI, 6.7-9.9) in the Asian and Western populations, respectively. The normal AET differed between the Asian and Western populations because the CI of the two groups did not overlap. CONCLUSIONS & INFERENCES The upper limit of normal of the AET in healthy Asian subjects was 3.2% (95% CI, 2.7-3.9%), which was lower than that of healthy Western subjects.

Abstract
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.

Abstract
OBJECTIVE The use of antisecretory drugs can provide symptomatic relief in 70-80% of patients suffering from gastro-oesophageal reflux disease (GORD), although this benefit is reduced by 20-30% in the case of nonerosive reflux disease (NERD). The current study evaluates the efficacy and safety of a patented oral formulation (liquid sachets containing hyaluronic acid, a mixture of amino acids including proline, hydroxyl-proline and glutamine, and rice extract dispersed in a bioadhesive polymer matrix) for relieving the symptoms of NERD. METHODS A single-centre, randomized, double-blind, parallel group, placebo-controlled clinical study was performed. Patients who experienced at least three episodes of moderate-severity heartburn during the 7-day run-in period were included and treated with three liquid sachets per day for 14 days. The primary objective was to evaluate the proportion of patients with at least a three-point reduction in the total symptom score (TSS). RESULTS Overall, 20 patients were randomized to receive the investigational product and 20 to receive the placebo. At the end of treatment, a three-point reduction in the TSS was achieved by 95% of patients treated with the investigational product and by 20% of patients treated with placebo (P < 0.0001). No adverse events were reported. CONCLUSION The investigational product showed a statistically significant superiority to the placebo in relieving common symptoms in patients with NERD. Future studies will be aimed at clarifying the hypothesis that this symptomatic benefit is related to the strengthening of the oesophageal barrier against the damage induced by gastric contents.

Prevalence and risk factors of gastroesophageal reflux disease in a rural Indian population. Indian J Gastroenterol 2021; 40:56-64. [PMID: 33443640 DOI: 10.1007/s12664-020-01135-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2020] [Accepted: 12/01/2020] [Indexed: 02/04/2023]
Abstract
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.

Prevalence, risk factors, and healthcare-seeking among subjects with esophageal symptoms: A community-based study in a rural Bangladeshi population. JGH Open 2020; 4:1167-1175. [PMID: 33319052 PMCID: PMC7731836 DOI: 10.1002/jgh3.12417] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2020] [Revised: 08/27/2020] [Accepted: 09/05/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND AND AIM As there is a scarcity of data on overall prevalence, risk factors, and health-care utilization of esophageal symptoms using the Rome criteria in the rural population in Asia, we undertook a study with the aims to evaluate: (i) the prevalence of heartburn, chest pain, globus, and dysphagia of presumed esophageal origin; (ii) the prevalence of functional esophageal disorders by Rome III criteria; (iii) the risk factors for esophageal symptoms; and (iv) the health-care utilization. METHODS This door-to-door survey was conducted in three villages (Charcharia, Churain of Dhaka district, and Kharrah of Munshiganj district of Bangladesh) among the adult population (≥18 years) using the translated and validated Enhanced Asian Rome III questionnaire. RESULTS Of 3559 individuals, 3351 (94.15%) responded (mean age 40.41 ± 16.04 years, female, 1924 [57.4%]). Heartburn was the most common symptom, 863 (25.8%), followed by chest pain, 367 (11%); globus, 285 (8.5%); and dysphagia, 146 (4.4%). At least one symptom was present in 1108 (33.1%) respondents. Based on Rome III criteria, 428 (12.8%), 41 (1.2%), 49 (1.5%), 26 (0.8%), and 524 (15.6%) had heartburn, chest pain, globus, dysphagia, and at least one functional esophageal disorder, respectively. Female gender, lower family income, presence of functional dyspepsia-irritable bowel syndrome (FD-IBS) overlap, FD only, and psychological distress were found to be risk factors for esophageal symptoms on multivariate analysis. Among the subjects with any esophageal disorders, 156 (14.1%) consulted any health-care provider, and 517 (46.6%) took antisecretory medications. CONCLUSION Esophageal symptoms are common in the rural community of Bangladesh and are associated with substantial health resource utilization.

Marques de Sá I, Pereira AD, Sharma P, Dinis-Ribeiro M. Systematic review of the published guidelines on Barrett's esophagus: should we stress the consensus or the differences? Dis Esophagus 2020:doaa115. [PMID: 33249488 DOI: 10.1093/dote/doaa115] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/14/2020] [Revised: 09/30/2020] [Accepted: 10/04/2020] [Indexed: 12/11/2022]
Abstract
Multiple guidelines on Barrett's esophagus (BE) have being published in order to standardize and improve clinical practice. However, studies have shown poor adherence to them. Our aim was to synthetize, compare, and assess the quality of recommendations from recently published guidelines, stressing similarities and differences. We conducted a search in Pubmed and Scopus. When different guidelines from the same society were identified, the most recent one was considered. We used the GRADE system to assess the quality of evidence. We included 24 guidelines and position/consensus statements from the European Society of Gastrointestinal Endoscopy, British Society of Gastroenterology, American Society for Gastrointestinal Endoscopy, American Gastroenterological Association, American College of Gastroenterology, Australian guidelines, and Asia-Pacific consensus. All guidelines defend that BE should be diagnosed when there is an extension of columnar epithelium into the distal esophagus. However, there is still some controversy regarding length and histology criteria for BE diagnosis. All guidelines recommend expert pathologist review for dysplasia diagnosis. All guidelines recommend surveillance for non-dysplastic BE, and some recommend surveillance for indefinite dysplasia. While the majority of guidelines recommend ablation therapy for low-grade dysplasia without visible lesion, others recommend ablation therapy or endoscopic surveillance. However, controversy exists regarding surveillance intervals and biopsy protocols. All guidelines recommend endoscopic resection followed by ablation therapy for neoplastic visible lesion. Several guidelines use the GRADE system, but the majority of recommendations are based on low and moderate quality of evidence. Although there is considerable consensus among guidelines, there are some discrepancies resulting from low-quality evidence. The lack of high-quality evidence for the majority of recommendations highlights the importance of continued well-conducted research in this field.

Abstract
BACKGROUND A proportion of patients with gastroesophageal reflux disease (GERD) do not respond to proton pump inhibitor (PPI) therapy. AIM OF THE STUDY To determine the findings on high-resolution esophageal manometry (HREM) and 24-h pH recording in patients with typical GERD symptoms, refractory to PPI treatment. METHODS Retrospective analysis of prospectively maintained database of patients referred for HREM and 24-h pH recording was done. We selected patients who were referred for evaluation of refractory GERD symptoms despite > 8 weeks of at least once-daily PPI treatment. Details noted were demographic profile, upper gastrointestinal endoscopy report, HREM findings and 24-h pH findings. RESULTS Ninety-six patients had symptoms of GERD that were refractory to PPI therapy. Seven patients (7.1%) were diagnosed having diseases mimicking GERD: eosinophilic esophagitis (n=2), supragastric belching (n=4) and rumination (n=1). After excluding these patients and those with insufficient data, the final study cohort included 82 cases. Fifty patients (61%) had normal motility. Major motility disorders were detected in 8 (9.75%) patients: achalasia cardia (6) and distal esophageal spasm (2). Ineffective esophageal motility was noted in 24 patients. A total of 74 patients underwent 24-h pH testing. Significant acid reflux with good symptom correlation was noted in 56 patients. Eighteen patients did not have significant acid reflux (Johnson-DeMeester score < 14.7): hypersensitive esophagus (12) and functional heartburn (6). CONCLUSION Fifty-six patients (68.3%) had definite diagnosis of GERD and 31.7% (26) had non-GERD conditions like motility disorders, functional heartburn and hypersensitive esophagus.
