ABSTRACT

OBJECTIVE: This systematic review investigates the prevalence of erosive tooth wear (ETW) in individuals classified as risk groups (gastroesophageal reflux disease, eating disorders, special diets, acidic beverage, drugs and alcohol, legal drugs and medications, and occupational or sports). MATERIALS AND METHODS: The research was conducted in nine databases (PubMed/MEDLINE, Embase, Cochrane Library, LILACS/BVS, SciELO, Scopus, Science Direct, Open Grey, and Web of Science) up to April 2024 (PROSPERO CRD42021270150), along with a manual search of grey literature. Observational studies involving children and adults from these previously mentioned risk groups, which provided data on ETW prevalence, were included without date or language restrictions. The methodological quality of studies was evaluated using the Joanna Briggs Institute's Prevalence Data Critical Appraisal Tool. General and subgroup data were meta-analyzed using a random-effects model. RESULTS: Overall, 4403 studies were retrieved, out of which 148 met the inclusion criteria. Each risk group showed higher prevalences of ETW in these patients in general and subgroup analysis; although subgroup analysis was not possible for all risk groups due to the heterogeneity of the indices found. CONCLUSIONS: The Legal drugs and Medications risk group showed lower overall prevalence values (30%), while the Drugs and Alcohol risk group obtained higher values (67%). Prevalence rates for other groups were: Gastroesophageal reflux disease (54.1%), Eating Disorders (65%), Special Diets (65.9%), Acidic Beverages (40%), Occupational and Sports (51%). CLINICAL RELEVANCE: This systematic review highlights that risk groups are indeed at significant risk for the development of ETW and greater preventive care and dental monitoring are needed.

ABSTRACT

BACKGROUND: Oesophageal disorders and chronic liver disease are common worldwide and significantly impact quality of life. The intricate link between these conditions, including how oesophageal disorders like GERD, Barrett's oesophagus and oesophageal cancer affect and are affected by chronic liver disease, remains poorly understood. AIMS: To review the relationship between oesophageal disorders and chronic liver disease, evaluating epidemiology, pathophysiology and therapeutic factors. METHODS: We reviewed the literature on the relationship between oesophageal disorders and chronic liver disease, including cirrhosis, using the PubMed database RESULTS: Oesophageal disorders such as gastroesophageal reflux disease, Barrett's oesophagus, oesophageal cancer, oesophageal motor disorders and oesophageal candidiasis are prevalent among individuals with cirrhosis, exacerbating the burden of liver disease. These diseases have a multifaceted symptomatology and pathogenic basis, posing a significant challenge in cirrhotic patients that necessitates careful diagnosis and management. Additionally, therapies frequently used for these diseases, such as proton pump inhibitors, require careful consideration in cirrhotic patients due to potential adverse effects and altered pharmacokinetics. Managing oesophageal disorders in cirrhotic patients requires a cautious approach due to possible interactions with medications and the risk of adverse effects. Furthermore, symptoms associated with these conditions are often exacerbated by common interventions in patients with cirrhosis, such as band ligation for oesophageal varices. CONCLUSIONS: Oesophageal disorders are common in cirrhosis and increase the disease burden. These conditions require careful management due to complex symptoms and treatment risks. Proton pump inhibitors and other therapies must be used cautiously, as cirrhosis interventions can worsen symptoms.

ABSTRACT

INTRODUCTION: Esophageal pH-impedance monitoring is a tool for diagnosing gastroesophageal reflux in children. The position of the pH catheter is essential for a reliable reading and the current formulas for calculating catheter insertion length are not completely accurate. The aim of the present study was to develop a new formula for adequate insertion of the pH catheter. MATERIAL AND METHODS: A cross-sectional study was conducted on children that underwent pH-impedance monitoring and later radiographic control, to calculate the correct catheter insertion length. The documented variables were age, sex, weight, height, naris to tragus distance, tragus to sternal notch distance, sternal notch to xiphoid process distance, and initial insertion length determined by the Strobel and height interval formulas. A multivariate regression analysis was carried out to predict the final insertion length. Regression ANOVA and Pearson's adjusted R-squared tests were performed. RESULTS: Forty-five pH-impedance studies were carried out, 53% of which were in males. The age and weight variables were not normally distributed. In the initial regression model, the variables that did not significantly correlate with the final insertion length were: sex (P 0.124), length determined by the Strobel or height interval formulas (P 0.078), naris to tragus distance (P 0.905), and tragus to sternal notch distance (P 0.404). The final equation: 5.6 + (height in cm * 0.12) + (sternal notch to xiphoid process distance * 0.57) produced an R2 of 0.93 (P 0.000). CONCLUSIONS: This formula can be considered a valid option for placement of the pH-impedance monitoring catheter in pediatrics.

ABSTRACT

OBJECTIVE: To examine the biomarkers of pharyngoesophageal swallowing during oral feeding sessions in infants undergoing pH-impedance testing and determine whether swallow frequencies are distinct between oral-fed and partially oral-fed infants. STUDY DESIGN: One oral feeding session was performed in 40 infants during pH-impedance studies and measurements included swallowing frequency, multiple swallow rate, air and liquid swallow rates, esophageal swallow clearance time, and gastroesophageal reflux (GER) characteristics. Linear and mixed statistical models were applied to examine the swallowing markers and outcomes. RESULTS: Infants (30.2 ± 4.4 weeks' birth gestation) were evaluated at 41.2 ± 0.4 weeks' postmenstrual age. Overall, 10 675 swallows were analyzed during the oral feeding sessions (19.3 ± 5.4 minutes per infant) and GER events were noted (2.5 ± 0.3 per study). Twenty-four-hour acid reflux index (ARI) was 9.5 ± 2.0%. Differences were noted in oral-fed and partially oral-fed infants for volume consumption (P < .01), consumption rate (P < .01), and length of hospital stay in days (P < .01). Infants with ARI >7% had greater frequency of swallows (P = .01). The oral-fed group had greater ARI (12.7 ± 3.3%, P = .05). CONCLUSIONS: Oropharyngeal swallowing regulatory characteristics decrease over the feeding duration and were different between ARI >7% vs ≤7%. Although GER is less in infants who are partially oral-fed, the neonates with increased acid exposure achieved greater oral intakes and shorter hospitalizations, despite the presence of comorbidities. Pharyngoesophageal stimulation as during consistent feeding or GER events can activate peristaltic responses and rhythms, which may be contributory to the findings.

ABSTRACT

The objective of this work was to estimate the prevalence and severity of erosive tooth wear (ETW), and to identify risk indicators of deciduous dentition of a group of schoolchildren from public schools in Tlalnepantla de Baz, State of Mexico. A cross-sectional study was carried out in 352 schoolchildren from 5 to 7 years old. The severity of the ETW was evaluated using the Basic Erosive Wear Examination (BEWE). Risk indicators were evaluated through a survey which included food and beverage consumption, consumption habits, vitamin C consumption, gastroesophageal reflux, heartburn, belching, xerostomia, vomiting and teeth grinding. Multinomial logistic regression models were fitted. The prevalence of ETW was 99.7% (n = 351). Regarding severity, 46.6% were at a null/mild level, 27.3% moderate, and 26.1% severe. Males were more likely to present severe ETW (odds ratio (OR) = 2.23, 95% confidence interval (CI), 1.27-3.93; p = 0.005). The risk indicators for the severity of ETW were the frequent consumption of citrus fruits (OR = 2.09, 95% CI, 1.12-3.89; p = 0.021), fruit juice (OR = 1.99, 95% CI, 1.06-3.75; p = 0.033), processed beverages (OR = 2.15, 95% CI, 1.23-3.78; p = 0.008) and hot sauce (OR = 1.82, 95% CI, 1.03-3.20; p = 0.036). The prevalence of ETW in the deciduous dentition was very high (99.7%) and ~1/3 for severe ETW. The dietary factors associated with severe ETW are part of the regular consumption of Mexican school-age children, which impact their oral health condition. It is important to establish intervention strategies from the infant stage, focused on both children and their caregivers.

ABSTRACT

The endoscopic treatment of gastroesophageal reflux disease (GERD) has evolved significantly in the past 20 years. Current practices include devices specifically designed for GERD. Newer techniques aim to use less extra equipment, to be less costly, and to use accessories readily available in endoscopy units, as well as using standard endoscopes to apply such techniques. It is of utmost importance to properly select the patients for endoscopic therapy, and it should be done in a multidisciplinary approach.


El tratamiento endoscópico de la enfermedad por reflujo gastroesofágico (ERGE) ha evolucionado significativamente en los últimos 20 años. Las prácticas actuales incluyen dispositivos diseñados específicamente para la ERGE. Las técnicas más nuevas tienen como objetivo utilizar menos equipos adicionales, ser menos costosos y utilizar accesorios fácilmente disponibles en las unidades de endoscopia, así como utilizar endoscopios estándar para aplicar dichas técnicas. Es de suma importancia seleccionar adecuadamente a los pacientes para la terapia endoscópica, y debe hacerse en un enfoque multidisciplinario.

ABSTRACT

Hiatal hernia (HH) is a common disease in the general population. It is often asymptomatic, but if it does present clinical manifestations, these are usually gastrointestinal. Gastroesophageal reflux is the main symptom that accompanies it. Depending on the severity of the hernia, it is classified into several subtypes from I-IV. Especially, IV type (giant HH) can lead to various cardiopulmonary symptoms with several degrees of severity. It is necessary to keep this possibility in mind among the various differential diagnoses that may occur in this clinical setting. The current paper aims to review the literature on classic and novel information on the HH - cardiovascular system relationship. Epidemiological data, physiological aspects of the heart compressed by HH, cardiovascular symptoms, electrocardiographic changes, echocardiographic alterations and clinical implications are discussed.


Normally, the stomach and the heart are not in direct contact because they are in different cavities, the thorax and the abdomen, respectively. When part of the stomach moves toward the chest through the diaphragm, we say there is a hiatal hernia (HH). Most of the time the HH symptoms are mild and clearly digestive. In severe cases, surgical repair of the HH is required. Even in these circumstances, digestive symptoms continue to be the most frequent. However, some patients present cardiovascular symptoms and few or no digestive symptoms. This easily creates diagnostic confusion, which leads to incorrect treatments and unnecessary expenses. In extreme cases, as seen in giant HH, the degree of cardiovascular involvement is very serious. There are documented cases that have suffered cardiac arrest, arrhythmias of different types and symptoms like classic acute myocardial infarction. It is required that clinical doctors and surgeons are aware that this complication exists. Only with this in mind can a timely diagnosis be achieved. Some emergency measures have been saving, gastric decompression with a tube being the most important. The main mechanism that explains the serious cardiovascular consequences of giant HH is cardiac compression. The dissemination of this knowledge can help save lives.

ABSTRACT

Asthma and obstructive sleep apnea (OSA) are common respiratory disorders. They share characteristics such as airway obstruction, poor sleep quality, and low quality of life. They are often present as comorbidities, along with obesity, gastroesophageal reflux disease (GERD), and allergic rhinitis (AR), which impacts the disease's control. In recent years, there has been discussion about the association between these conditions and their pathophysiological and clinical consequences, resulting in worse health outcomes, increased healthcare resource consumption, prolonged hospital stays, and increased morbidity and mortality. Some studies demonstrate that treatment with continuous positive airway pressure (CPAP) can have a beneficial effect on both pathologies. This review summarizes the existing evidence of the association between asthma and OSA at their pathophysiological, epidemiological, clinical, and therapeutic levels. It intends to raise awareness among healthcare professionals about these conditions and the need for further research.

ABSTRACT

Gastroesophageal reflux (GER) is a frequent normal phenomenon in children of any age. It is more common in infants, in whom the majority of episodes are short-lived and cause no other symptoms or complications, differentiating it from gastroesophageal reflux disease (GERD). The diagnosis and management of GER and GERD continue to be a challenge for the physician. Therefore, the aim of the Asociación Mexicana de Gastroenterología was to adapt international documents to facilitate their adoption by primary care physicians, with the goal of standardizing quality of care and reducing the number of diagnostic tests performed and inappropriate medication use. The ADAPTE methodology was followed, and the recommendations were approved utilizing the Delphi strategy. The executive committee carried out the review of the guidelines, position papers, and international reviews that met the a priori quality criteria and possible applicability in a local context. The recommendations were taken from those sources and adapted, after which they were approved by the working group. The consensus consists of 25 statements and their supporting information on the diagnosis and treatment of GER and GERD in infants. The adapted document is the first systematic effort to provide an adequate consensus for use in Mexico, proposing a practical approach to and management of GER and GERD for healthcare providers.

ABSTRACT

OBJECTIVE: To determine associations between presenting symptoms and oropharyngeal dysphagia diagnoses, gastroesophageal reflux disease (GERD) diagnoses, and treatment with acid suppression medication in infants with brief resolved unexplained event (BRUE). STUDY DESIGN: We performed a prospective cohort study of infants with BRUE to review presenting symptoms and their potential impact on testing and treatment. Videofluoroscopic swallow study (VFSS) results and explanatory diagnoses were obtained from medical record review; acid suppression use was determined by parental survey. Binary and multivariable logistic regression models were used to evaluate associations between presenting symptoms and obtaining VFSS, VFSS results, GERD diagnoses, and acid suppression medication. RESULTS: Presenting symptoms were varied in 157 subjects enrolled at 51.0 ± 5.3 days of age, with many symptoms that may be related to GERD or dysphagia. Of these, 28% underwent VFSS with 71% abnormal. Overall, 42% had their BRUE attributed to GERD, and 33% were treated with acid suppression during follow-up. Presenting symptoms were significantly associated with the decision to obtain VFSS but not with abnormal VFSS results. Presenting symptoms were also associated with provision of GERD explanatory diagnoses. Both presenting symptoms and GERD explanatory diagnoses were associated with acid suppression use (aOR 2.3, 95% CI 1.03-5.3, P = .04). CONCLUSIONS: Presenting symptoms may play a role in clinicians' decisions on which BRUE patients undergo VFSS but are unreliable to make a diagnosis of oropharyngeal dysphagia. Presenting symptoms may also influence assignment of GERD explanatory diagnoses that is associated with increased acid suppression medication use.

ABSTRACT

INTRODUCTION: Gastroesophageal reflux disease (GERD) is very prevalent in the general population, with a broad spectrum of clinical manifestations, requiring accurate diagnosis and treatment. AIM: The aim of this expert review is to establish good clinical practice recommendations for the diagnosis and personalized treatment of GERD. METHODS: The good clinical practice recommendations were produced by a group of experts in GERD, members of the Asociación Mexicana de Gastroenterología (AMG), after carrying out an extensive review of the published literature and discussing each recommendation at a face-to-face meeting. This document does not aim to be a clinical practice guideline with the methodology such a document requires. RESULTS: Fifteen experts on GERD formulated 27 good clinical practice recommendations for recognizing the symptoms and complications of GERD, the rational use of diagnostic tests and medical treatment, the identification and management of refractory GERD, the overlap with functional disorders, endoscopic and surgical treatment, and GERD in the pregnant woman, older adult, and the obese patient. CONCLUSIONS: An accurate diagnosis of GERD is currently possible, enabling the prescription of a personalized treatment in patients with this condition. The goal of the good clinical practice recommendations by the group of experts from the AMG presented in this document is to aid both the general practitioner and specialist in the process of accurate diagnosis and treatment, in the patient with GERD.

ABSTRACT

BACKGROUND: Magnetic ring (MSA) implantation in the esophagus is an alternative surgical procedure to fundoplication for the treatment of gastroesophageal reflux disease. AIMS: The aim of this study was to analyse the effectiveness and safety of magnetic sphincter augmentation (MSA) in patients with gastroesophageal reflux disease (GERD). METHODS: A systematic literature review of articles on MSA was performed using the Medical Literature Analysis and Retrieval System Online (Medline) database between 2008 and 2021, following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A random-effect model was used to generate a pooled proportion with 95% confidence interval (CI) across all studies. RESULTS: A total of 22 studies comprising 4,663 patients with MSA were analysed. Mean follow-up was 27.3 (7-108) months. The weighted pooled proportion of symptom improvement and patient satisfaction were 93% (95%CI 83-98%) and 85% (95%CI 78-90%), respectively. The mean DeMeester score (pre-MSA: 34.6 vs. post-MSA: 8.9, p=0.03) and GERD-HRQL score (pre-MSA: 25.8 vs. post-MSA: 4.4, p<0.0001) improved significantly after MSA. The proportion of patients taking proton pump inhibitor (PPIs) decreased from 92.8 to 12.4% (p<0.0001). The weighted pooled proportions of dysphagia, endoscopic dilatation and gas-related symptoms were 18, 13, and 3%, respectively. Esophageal erosion occurred in 1% of patients, but its risk significantly increased for every year of MSA use (odds ratio - OR 1.40, 95%CI 1.11-1.77, p=0.004). Device removal was needed in 4% of patients. CONCLUSIONS: Although MSA is a very effective treatment modality for GERD, postoperative dysphagia is common and the risk of esophageal erosion increases over time. Further studies are needed to determine the long-term safety of MSA placement in patients with GERD.

ABSTRACT

BACKGROUND: Gastroesophageal Reflux Disease (GERD) is a prevalent condition in Brazil, affecting 12% to 20% of the urban population, with significant implications for patient quality of life and potential for complications. OBJECTIVE: This paper focuses on the recent update of the Brazilian guidelines for GERD, a necessary revision due to advancements in knowledge and practice since the last publication over a decade ago. The update pays particular attention to the role and safety of proton pump inhibitors (PPIs), acknowledging the growing concerns about their long-term use, adverse events, and overprescription. METHODS: The methodology of the guideline update involved an extensive literature review in multiple languages (English, French, Italian, Spanish, and Portuguese), drawing from major databases such as Medline, Embase, and SciELO-Lilacs. RESULTS: This comprehensive approach resulted in a carefully curated selection of studies, systematic reviews, and meta-analyses, specifically focusing on PPIs and other therapeutic strategies for GERD. The updated guidelines are presented in a user-friendly question-and-answer format, adhering to the PICO system (Population, Intervention, Comparison, Outcomes) for clarity and ease of interpretation. The recommendations are supported by robust scientific evidence and expert opinions, enhancing their practical applicability in clinical settings. To ensure the reliability and clarity of the recommendations, the GRADE system (Grading of Recommendations Assessment, Development, and Evaluation) was employed. This system categorizes the strength of recommendations as strong, weak, or conditional and classifies evidence quality as high, moderate, low, or very low. These classifications provide insight into the confidence level of each recommendation and the likelihood of future research impacting these guidelines. CONCLUSION: The primary aim of these updated guidelines is to offer practical, evidence-based advice for the management of GERD in Brazil, ensuring that healthcare professionals are equipped with the latest knowledge and tools to deliver optimal patient care. BACKGROUND: •Gastrointestinal specialists rely heavily on guidelines to manage digestive pathologies effectively. The Brazilian clinical guideline for therapeutic management of gastroesophageal reflux disease (GERD) is an invaluable tool for these specialists. BACKGROUND: •It critically analyzes practical aspects of therapy through 12 questions covering a wide range of topics, from behavioral measures to surgical and endoscopic indications. BACKGROUND: •The recommendations in this guideline are justified using the GRADE system (Grading of Recommendations Assessment, Development, and Evaluation), and experienced experts provide comments and suggestions at the end of each question.

ABSTRACT

OBJECTIVES: Angico gum (AG) (Anadenanthera colubrina var. Cebil [Griseb.] Altschul) is utilized by some Brazilian communities to alleviate symptoms from gastroesophageal reflux disease. Here, we aimed to investigate the "in vitro" topical protective capacity of AG on human esophageal mucosa. METHODS: Biopsies of the distal esophageal mucosa were collected from 35 patients with heartburn (24 non-erosive and 11 with erosive oesophagitis (EE)) and mounted in Üssing chambers. AG was applied topically, followed by exposure with acid solution (pH 2.0 or pH 1.0), where transepithelial electrical resistance (TER) and The transepithelial permeability for fluorescein was assessed. The incubation of the AG labeled with FITC in the esophageal mucosa was localized by fluorescence microscopy. KEY FINDINGS: Pretreatment with AG prevented the drop in TER induced by acid solution, as well as significantly decreases the fluorescein permeability in non-erosive patients. The protective effect of AG was sustained for up to 120 min both in biopsies of non-erosive and erosive esophagitis. Confocal microscope images showed mucosal luminal adherence of FITC-labeled AG. CONCLUSION: AG had a prolonged topical protective effect against acid solution in mucosal biopsies of patients with non-erosive and erosive esophagitis.

ABSTRACT

Large hiatal hernias, besides being more prevalent in the elderly, have a different clinical presentation: less reflux, more mechanical symptoms, and a greater possibility of acute, life-threatening complications such as gastric volvulus, ischemia, and visceral mediastinal perforation. Thus, surgical indications are distinct from gastroesophageal reflux disease-related sliding hiatal hernias. Heartburn tends to be less intense, while symptoms of chest pain, cough, discomfort, and tiredness are reported more frequently. Complaints of vomiting and dysphagia may suggest the presence of associated gastric volvulus. Signs of iron deficiency and anemia are found. Surgical indication is still controversial and was previously based on high mortality reported in emergency surgeries for gastric volvulus. Postoperative mortality is especially related to three factors: body mass index above 35, age over 70 years, and the presence of comorbidities. Minimally invasive elective surgery should be offered to symptomatic individuals with good or reasonable performance status, regardless of age group. In asymptomatic and oligosymptomatic patients, besides obviously identifying the patient's desire, a case-by-case analysis of surgical risk factors such as age, obesity, and comorbidities should be taken into consideration. Attention should also be paid to situations with greater technical difficulty and risks of acute migration due to increased abdominal pressure (abdominoplasty, manual labor, spastic diseases). Technical alternatives such as partial fundoplication and anterior gastropexy can be considered. We emphasize the importance of performing surgical procedures in cases of large hiatal hernias in high-volume centers, with experienced surgeons.

ABSTRACT

Gastro-oesophageal reflux disease (GERD) is a common gastrointestinal disorder in which retrograde flow of gastric content into the oesophagus causes uncomfortable symptoms and/or complications. It has a multifactorial and partially understood pathophysiology. GERD starts in the stomach, where the refluxate material is produced. Following the trajectory of reflux, the failure of the antireflux barrier, primarily the lower oesophageal sphincter and the crural diaphragm, enables the refluxate to reach the oesophageal lumen, triggering oesophageal or extra-oesophageal symptoms. Reflux clearance mechanisms such as primary and secondary peristalsis and the arrival of bicarbonate-rich saliva are critical to prevent mucosal damage. Alterations of the oesophageal mucosal integrity, such as macroscopic oesophagitis or microscopic changes, determine the perception of symptoms. The intensity of the symptoms is affected by peripheral and central neural and psychological mechanisms. In this Review, we describe an updated understanding of the complex and multifactorial pathophysiology of GERD. It is now recognized that different GERD phenotypes have different degrees of reflux, severity of mucosal integrity damage and type, and severity of symptoms. These variations are probably due to the occurrence of a predominant pathophysiological mechanism in each patient. We also describe the main pathophysiological mechanisms of GERD and their implications for personalized diagnosis and management.

ABSTRACT

BACKGROUND: Diagnosing gastroesophageal reflux disease (GERD) can be challenging given varying symptom presentations, and complex multifactorial pathophysiology. The gold standard for GERD diagnosis is esophageal acid exposure time (AET) measured by pH-metry. A variety of additional diagnostic tools are available. The goal of this consensus was to assess the individual merits of GERD diagnostic tools based on current evidence, and provide consensus recommendations following discussion and voting by experts. METHODS: This consensus was developed by 15 experts from nine countries, based on a systematic search of the literature, using GRADE (grading of recommendations, assessment, development and evaluation) methodology to assess the quality and strength of the evidence, and provide recommendations regarding the diagnostic utility of different GERD diagnosis tools, using AET as the reference standard. KEY RESULTS: A proton pump inhibitor (PPI) trial is appropriate for patients with heartburn and no alarm symptoms, but nor for patients with regurgitation, chest pain, or extraesophageal presentations. Severe erosive esophagitis and abnormal reflux monitoring off PPI are clearly indicative of GERD. Esophagram, esophageal biopsies, laryngoscopy, and pharyngeal pH monitoring are not recommended to diagnose GERD. Patients with PPI-refractory symptoms and normal endoscopy require reflux monitoring by pH or pH-impedance to confirm or exclude GERD, and identify treatment failure mechanisms. GERD confounders need to be considered in some patients, pH-impedance can identify supragrastric belching, impedance-manometry can diagnose rumination. CONCLUSIONS: Erosive esophagitis on endoscopy and abnormal pH or pH-impedance monitoring are the most appropriate methods to establish a diagnosis of GERD. Other tools may add useful complementary information.

ABSTRACT

OBJECTIVE: This study aimed to evaluate the role of pepsin inhibitors in the inflammatory response and their effects on laryngeal mucosal integrity during gastroesophageal reflux (GERD) under in vivo conditions. METHODS: A surgical model of GERD was used, in which mice were treated with pepstatin (0.3 mg/kg) or darunavir (8.6 mg/kg) for 3 days. On the third day after the experimental protocol, the laryngeal samples were collected to assess the severity of inflammation (wet weight and myeloperoxidase activity) and mucosal integrity (transepithelial electrical resistance and paracellular epithelial permeability to fluorescein). RESULTS: The surgical GERD model was reproduced. It showed features of inflammation and loss of barrier function in the laryngeal mucosa. Pepstatin and darunavir administration suppressed laryngeal inflammation and preserved laryngeal mucosal integrity. CONCLUSION: Pepsin inhibition by the administration of pepstatin and darunavir improved inflammation and protected the laryngeal mucosa in a mouse experimental model of GERD.

ABSTRACT

This systematic review and meta-analysis evaluated the efficacy of dexlansoprazole (a proton pump inhibitor-PPI) in resolving heartburn, reflux, and other symptoms and complications resulting from gastroesophageal reflux disease (GERD). The study followed PRISMA 2020 and was registered in PROSPERO (CRD42020206513). The search strategy used MeSH and free terms appropriately adapted for each database. Only randomized clinical trials (RCTs) were included. The Cochrane tool (RoB 2.0) was used to assess the risk of bias, and the certainty of evidence was rated using GRADE. Ten RCTs were included. Dexlansoprazole outperformed the placebo and other PPIs in the resolution of heartburn and reflux symptoms in patients with GERD, with benefits during and after treatment, especially in those with moderate and severe symptoms. The meta-analyses indicated that dexlansoprazole at doses of 30 and 60 mg had more 24 h heartburn-free days and nights compared to the placebo medications; no difference was reported between dexlansoprazole at doses of 30 and 60 mg in heartburn-free nights. A low bias risk and a moderate certainty of evidence were observed. This review confirms the therapeutic effect of dexlansoprazole (placebo-controlled) and its improvements in GERD symptoms compared to another PPI. However, the interpretation of the results should be carried out cautiously due to the small number of included studies and other reported limitations.
