Randomised clinical trial: comparison of tegoprazan and placebo in non-erosive reflux disease. Aliment Pharmacol Ther 2021; 54:402-411. [PMID: 34227708 PMCID: PMC8361733 DOI: 10.1111/apt.16477] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2021] [Revised: 02/23/2021] [Accepted: 05/20/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND Tegoprazan is a novel, fast- and long-acting potassium-competitive acid blocker that suppresses gastric acid secretion, which could benefit patients with non-erosive reflux disease (NERD), a type of gastroesophageal reflux disease. AIM To evaluate the efficacy and safety profiles of tegoprazan compared with those of a placebo in Korean patients with NERD. METHODS In this phase 3, double-blind, placebo-controlled, multicentre study, 324 Korean patients with NERD were randomised into three treatment groups: tegoprazan 50 mg, tegoprazan 100 mg and placebo. These drugs were provided once daily for 4 weeks. The primary endpoint was the proportion of patients with complete resolution of major symptoms (both heartburn and regurgitation) for the last 7 days of the 4-week treatment period. Other outcomes related to efficacy, safety and tolerability were also evaluated. RESULTS Among all, 42.5% (45/106), 48.5% (48/99) and 24.2% (24/99) of patients showed complete resolution of major symptoms at week 4 after receiving tegoprazan 50 mg, tegoprazan 100 mg, and placebo, respectively. Both doses of tegoprazan showed superior efficacy than the placebo (P = 0.0058 and P = 0.0004, respectively). The complete resolution rates of heartburn and proportions of heartburn-free days (as other efficacy outcomes) were significantly higher in both tegoprazan groups than in the placebo group (P < 0.05 for all). No significant difference in the incidence of treatment-emergent adverse events were noted. CONCLUSIONS Tegoprazan 50 and 100 mg showed superior therapeutic efficacy compared with the placebo, as well as a favourable safety profile in patients with NERD. Registration number: ClinicalTrials.gov identifier NCT02556021.

Abstract
BACKGROUND No detailed quantitative global, regional, or national estimates of the disability-adjusted life years (DALYs) of type 2 diabetes mellitus (T2DM) are available. METHODS We used data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2017 to estimate the global, regional, and national incidence rates and DALYs of T2DM, as well as the associated risk factors, in all 194 countries and territories by age, sex, and sociodemographic status during the period from 2007 to 2017. RESULTS Globally, the age-standardized incidence and DALY rates increased by 3.23% and 5.07% during 2007 to 2017, respectively. The age-standardized incidence and DALY rates in 2017 and the corresponding percentage changes during 2007 to 2017 were highest in the low-middle sociodemographic index (SDI) quintile. Regionally, the highest 2017 age-standardized incidence and DALY rates were observed in Oceania, whereas the largest percentage increases in both rates during 2007 to 2017 were observed in Southeast Asia. Nationally, Iran, the United Kingdom, and Indonesia reported the largest percentage increases in the age-standardized incidence rates, whereas Georgia, Czech Republic, and Iran showed the largest percentage increases in the age-standardized DALY rates. Globally, the largest percentage increases in risk-attributable DALYs were associated with a high body mass index, low physical activity level, high fasting plasma glucose level, and high sugar-sweetened beverage and red meat consumption. CONCLUSIONS The global T2DM age-standardized incidence and DALY rates increased globally between 2007 and 2017, especially in the low-middle SDI quintile, Southeast Asia.

Abstract
Background/Aims Esophageal high-resolution manometry (HRM) enables the comprehensive evaluation of the esophageal motor function. However, protocols are not uniform and clinical practices vary widely among institutions. This study aims to understand the current HRM practice in Korea. Methods The survey was sent via email through the Korean Society of Neurogastroenterology and Motility. The questions covered descriptive information, preparation, techniques, analysis, and reporting of esophageal HRM. Results The survey was completed in 32 (74.4%) out of 43 centers, including 24 tertiary and 8 secondary referral centers. Of the 32 centers, 25 (78.1%) performed HRM in a sitting position, while 7 centers (21.9%) reported performing HRM in a supine position. All the centers utilized single wet swallows as a standard, but the volume, frequency, and interval between swallows varied widely. Sixteen centers (50.0%) applied adjunctive tests, including multiple rapid swallows (n = 16) and rapid drink challenges (n = 9). Parameters assessed and documented in the report were similar. In addition to the assessment of the esophagogastric junction and esophageal body, 27 centers (84.8%) and 18 centers (56.3%) included measurements for the upper esophageal sphincter and the pharynx, respectively, in the HRM protocol. Conclusions We found a variation in the available HRM practice among centers, even though they broadly agreed in the data analysis. Efforts are needed to develop a standardized protocol for HRM measurement.

Abstract
OBJECTIVE This study aims to investigate the detection rates, common symptoms and risk factors of gastroesophageal reflux disease (GERD), and laryngopharyngeal reflux disease (LPRD) at the digestive endoscopy center. METHODS A multicenter cross-sectional survey conducted at three hospitals and a total of 565 eligible participants were enrolled. All the patients completed routine ENT examination, gastroscopy, gastroesophageal reflux questionnaire (GerdQ), reflux symptom index (RSI) and a self-designed 25-item symptoms table survey. RESULTS Among the 565 eligible participants, the detection rates of GERD and LPRD were 18.41% (104/565) and 9.91% (56/565), respectively. The detection rate of GERD combined with LPRD was 3.19% (18/565). Among GERD and LPRD patients, males (vs. females), middle-aged and elderly patients (vs. young people), BMI ≥ 24.0 kg/m2 (vs. BMI < 24.0 kg/m2), with current smoking history (vs. no smoking), and current drinking history (vs. no drinking), lying down immediately after meal (vs. no lying down immediately after meal) were significantly higher (all p < 0.05). The most common extraesophageal symptoms in patients with GERD were dry mouth (66.35%), globus sensation (56.73%), dry throat and pharyngeal itching (55.77%). The most common extraesophageal symptoms in patients with LPRD were globus sensation (91.07%), dry throat and pharyngeal itching (83.93%), and dry mouth (82.14%). CONCLUSION GERD and LPRD had a high detection rate at the digestive endoscopy center in Guangzhou, China. Older age, BMI ≥ 24.0 kg/m2, smoking and drinking history were risk factors for both GERD and LPRD. Neither GerdQ nor RSI scores included common extraesophageal symptoms.

Abstract
Liver fibrosis is a leading cause of death worldwide, accounting for approximately 2 million deaths annually. Despite its wide prevalence, there are currently no pharmacological therapies that directly reverse the fibrotic process in patients. Studies over the last decade have revealed that liver fibrosis is reversible in patients and in animal models. Further, studies aimed at elucidating the mechanism of fibrosis reversal have revealed that macrophages are central to this process. During resolution of fibrosis, proinflammatory macrophages shift phenotype to pro-resolution macrophages which produce matrix degrading enzymes and mediators that inactivate hepatic stellate cells, the cell type principally involved in matrix production during fibrosis development. Since fibrosis reversal begins when disease-causing macrophages transition to disease-reversing macrophages, studies have focused on identifying pharmacological agents that stimulate this process to occur. If successful, these "drugs" would constitute a first-in-class, macrophage-targeted therapeutic approach to reverse liver fibrosis. In the following review, we summarize the current approaches under investigation to modify macrophage phenotype for liver disease treatment. Further we discuss the potential of other approaches to identify novel macrophage-targeted drugs that modify the phenotype of these cells.

Abstract
The underlying causes of heartburn, characteristic symptom of gastroesophageal reflux disease (GERD), remain incompletely understood. Superficial afferent innervation of the esophageal mucosa in nonerosive reflux disease (NERD) may drive nociceptive reflux perception, but its acid-sensing role has not yet been established. Transient receptor potential vanilloid subfamily member-1 (TRPV1), transient receptor potential melastatin 8 (TRPM8), and acid-sensing ion channel 3 (ASIC3) are regulators of sensory nerve activity and could be important reflux-sensing receptors within the esophageal mucosa. We characterized TRPV1, TRPM8, and ASIC3 expression in esophageal mucosa of patients with GERD. We studied 10 patients with NERD, 10 with erosive reflux disease (ERD), 7 with functional heartburn (FH), and 8 with Barrett's esophagus (BE). Biopsies obtained from the distal esophageal mucosa were costained with TRPV1, TRPM8, or ASIC3, and CGRP, CD45, or E-cadherin. RNA expression of TRPV1, TRPM8, and ASIC3 was assessed using qPCR. Patients with NERD had significantly increased expression of TRPV1 on superficial sensory nerves compared with ERD (P = 0.028) or BE (P = 0.017). Deep intrapapillary nerve endings did not express TRPV1 in all phenotypes studied. ASIC3 was exclusively expressed on epithelial cells most significantly in patients with NERD and ERD (P ≤0.0001). TRPM8 was expressed on submucosal CD45+ leukocytes. Superficial localization of TRPV1-immunoreactive nerves in NERD, and increased ASIC3 coexpression on epithelial cells in NERD and ERD, suggests a mechanism for heartburn sensation. Esophageal epithelial cells may play a sensory role in acid reflux perception and act interdependently with TRPV1-expressing mucosal nerves to augment hypersensitivity in patients with NERD, raising the enticing possibility of topical antagonists for these ion channels as a therapeutic option.NEW & NOTEWORTHY We demonstrate for the first time that increased pain perception in patients with nonerosive reflux disease likely results from expression of acid-sensitive channels on superficial mucosal afferents and esophageal epithelial cells, raising the potential for topical therapy.

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
Background and Aim The risk factors associated with the increase in prevalence of gastroesophageal reflux disease (GERD) are not consistent across countries and there have been few studies in Asia in the past 10 years. This study was conducted to assess the features and risk factors of GERD in Vietnamese patients. Methods A cross-sectional study was conducted on 1947 out-patients ≥18 years of age who were presented with upper gastrointestinal symptoms and underwent esophagogastroduodenoscopy. Reflux esophagitis was graded according to the Los Angeles classification. Endoscopically suspected Barrett's esophagus (BE) was recorded according to the Prague C and M criteria and biopsy was taken for histologic examination. Results There were 511 (26.2%) patients with GERD, 242 (47.4%) with nonerosive reflux disease, and 269 (52.6%) with reflux esophagitis and/or BE. Epigastric pain, regurgitation, and heartburn were the chief complaints in 36.8%, 27.0%, and 9.2% of patients, respectively. Most of the patients with mucosal injury had reflux esophagitis in mild grade and BE in the form of C0M ≤2 (99.6%, 231/232 and 97.8%, 46/47, respectively). In multivariate analysis, hiatal hernia, male gender, waist-to-hip ratio (independent from general obesity), and smoking were risk factors for GERD while Helicobacter pylori infection was negatively associated with GERD. Conclusions The majority of GERD patients had none or mild mucosal injury. Typical reflux symptoms, however, may not be the chief complaints. Central obesity would be more important than general obesity as a risk factor, while H. pylori infection was a "protective" factor for GERD in Vietnamese patients.

Abstract
A primary care management strategy of gastroesophageal reflux disease (GERD) should pay attention to the epidemiology, prevalence, and distribution of reflux-like symptoms in the community and to the special characteristics of patients presenting for the first time with reflux symptoms in primary care. General practitioners (GPs) encounter daily challenges to make cost-effective differential diagnostic and therapeutic decisions, avoiding needless and costly investigation or referral. They should provide long-term effective control of symptoms and esophageal healing in a personalized, symptom-based, patient-centered, and evidence-based manner. GPs should use a practical system of triage in order to distinguish the high majority of patients with self-limiting conditions from the minority with alarm symptoms with potentially severe disorder. They should also discriminate between troublesome and nontroublesome reflux symptoms. Most GERD is uncomplicated and can be treated using management algorithms that make the best use of resources. Some strategies such as "step-down," "intermittent," or "on-demand" therapy can cost-effectively improve the long-term management and quality of life of patients with recurrent GERD. The accurate interpretation of "step-down" therapeutic strategy and a careful interpretation of proton pump inhibitor refractoriness are also essential.

Abstract
Hiatal hernia results from the translocation of intra-abdominal contents from their usual position into the thorax. They can be categorized into type I-IV which implies varying gradations of herniation. The symptomatology can range from just chest pain in the less severe types to respiratory and hemodynamic compromise resulting from strangulation in the advanced hernias. Our patient was an 81-year-old female with a past medical history of gastroesophageal reflux disease (GERD), deep venous thrombosis (DVT), hypertension, hyperlipidemia, coronary artery disease (CAD), and cerebrovascular accident (CVA), who presented to the emergency department (ED) with the chief complaint of chest pain. Assessment of the vitals in the ED revealed a temperature of 37.2 °C, respiratory rate of 18 breaths/minute with an oxygen saturation of 100% on room air, heart rate of 95 beats/min, and blood pressure reading of 132/110 mmHg. Due to significant concern of a possible coronary pathology leading to chest pain, the patient was given 325 mg of aspirin and one tablet of sublingual nitroglycerin. Her electrocardiogram (EKG) was unremarkable but the chest X-ray revealed a large retrocardiac hernia. The finding was corroborated after a review of the computerized tomography (CT) scan performed at the outlying facility. She was treated with omeprazole, a gastroenterologist was consulted, and an esophagogastroduodenoscopy (EGD) performed which revealed significant erosions in the distal esophagus and gastric antrum. She was deemed a high-risk surgical candidate for any intervention and thus managed conservatively with proton pump inhibitor (PPI) therapy. The case highlights the pertinent facts about hiatal hernia. Although the diagnosis of chest pain with the aforementioned comorbidities could be skewed towards coronary pathology, keeping a wide differential is important so that the right diagnosis can be made in a timely fashion and complications avoided.

Abstract
Summary
Background
Electrical stimulation therapy (EST) of the lower esophageal sphincter (LES) for gastro esophageal reflux disease (GERD) treatment increases LES pressure through chronic stimulation, with a low risk for gastrointestinal side effects and preservation of hiatal anatomy. The aim of this study was to evaluate the efficacy and safety of this novel technique in a high-output specialized reflux center.
Methods
This is a prospective single-center study including GERD patients indicated for anti-reflux therapy who consented to undergo LES-EST. Patients underwent prospective scheduled follow-up visits including interrogation of the stimulation device, clinical examination, and assessment of health-related quality of life (HRQL).
Results
Within a 4-year period, 37 LES-EST implantations were performed. The majority of patients were male (54.1%), mean BMI was 25.8 (SD 4.4), and mean age was 54.0 (SD 15.8). The median GERD HRQL composite score was 41 (IQR 21–49). Median total % of pH <4 was 10.1 (IQR 4.4–17.3). Six (16.2%) individuals underwent explantation of the entire system (IPG and leads) due to technical defect (n = 4) or failure of therapy (n = 2). HRQL score improved from 41 (IQR 21–49) to 8.50 (IQR 4.25–20.5, p < 0.001) and 9 (23.7%) patients were on at least occasional PPI treatment.
Conclusion
Due to the low rate of GI side effects and its minimal invasive character preserving the hiatal anatomy, this novel technique might find its place in anti-reflux surgery. However, the considerably high rate of device dysfunction needs further investigation.

Abstract
The two main drugs used in the treatment of gastro-oesophageal reflux disease are proton pump inhibitors and histamine-2 receptor antagonists and both these agents have been implicated in a number of adverse effects, leading to considerable controversies related to their long-term use. This paper is aimed at a critical review of the published literature and the clinical significance of these reported side effects, most of which are associations rather than causal.
