The treatment efficacy of adding prokinetics to PPIs for gastroesophageal reflux disease: a meta-analysis

Gastroesophageal reflux disease as a risk factor of dental hard tissues erosions

Gastroesophageal reflux disease (GERD) is a common chronic disease leading to a spontaneous and regular retrograde flow of gastric and/or duodenal contents into the esophagus. Reflux of the gastric contents into the oral cavity refers to the extraesophageal presentation of the disease, which, in the absence of timely treatment, can result in erosion of dental hard tissue (EDHT) through repeated exposure of the dental tissue to acidic contents. EDHT are non-carious lesions of the dental hard tissues (mainly enamel, and in some cases dentin), induced by a chemical reaction involving acids, which results in demineralization processes. The incidence rates of EDHT in adult patients with GERD are 32.5–51.5%. The EDHT in GERD develops in stages. Initially, the gradual degradation of tooth pelicula happens when it gradually becomes decayed by repeated acidic attacks. The loss of the pelicula results in direct contact of hydrochloric acid refluxate with the enamel surface and initiation of its demineralization at pH < 5.5 with dissolution of hydroxyapatite crystals. Given the high prevalence of GERD in the population, it seems important to update an integrated approach to the treatment of such patients, which involves pharmacotherapy provided by the gastroenterologist, as well as prevention and minimally invasive treatment of presentations in the oral cavity by the dentist. Patients with EDHT due to GERD need to maintain individual oral hygiene (use mouth washes with a neutral pH level, avoid abrasive toothpastes), use remineralization therapy at home applying remogels (Tooth Mousse), and also be observed by a dentist as part of the follow-up care. Minimally invasive treatment by the dentist involves restorations using composite tooth filling materials and ceramic veneers. It is reasonable to empirically use proton pump inhibitors twice a day for 3 months for the direct treatment of GERD in patients with EDHT.

Chinese expert consensus on diagnosis and management of gastroesophageal reflux disease in the elderly (2023)

Gastroesophageal reflux disease (GERD) in the elderly is characterized by atypical symptoms, relatively severe esophageal injury, and more complications, and when GERD is treated, it is also necessary to fully consider the general health condition of the elderly patients. This consensus summarized the epidemiology, pathogenesis, clinical manifestations, and diagnosis and treatment characteristics of GERD in the elderly, and provided relevant recommendations, providing guidance for medical personnel to correctly understand and standardize the diagnosis and treatment of GERD in the elderly.

Innovative therapeutic strategies in the treatment of gastroesophageal reflux disease (GERD): A review of progress and perspectives

Gastroesophageal Reflux Disease (GERD) is a commonly occurring condition that can significantly impact quality of life. Often considered a lifestyle disease. Traditional treatment methods focus on pharmacotherapy, lifestyle modifications, and in extreme cases, surgical interventions. This article discusses current and novel approaches to managing gastroesophageal reflux disease. The foundation of this work was medical articles and research gathered from the PubMed database. Keywords such as "esophageal reflux treatment", "new technologies in GERD treatment", "innovative reflux treatment methods", were used to facilitate the literature search. In managing gastroesophageal reflux disease, the application of appropriate pharmacological therapy and lifestyle changes for the patient remains key. However, new technologies and treatment methods, such as advanced endoscopic repair procedures, innovative medications, and personalized approaches, are gaining importance. These new strategies can significantly improve patients' quality of life, reduce symptoms, and minimize the need for surgical interventions.

[Current status and prospects of using the prokinetic acotiamide in gastroenterology: A review]

Acotiamide is a prokinetic with a novel mechanism of action - an antagonist of muscarinic M1 and M2 receptors and an acetylcholinesterase inhibitor. Acetylcholine is the central mediator of the tone of the muscular components of the gastrointestinal tract, increasing its motor activity. Blockade of presynaptic M1 and M2 receptors neutralizes the inhibitory effect of the feedback mechanism on the acetylcholine synthesis, while inhibition of acetylcholinesterase in the synaptic cleft reduces the acetylcholine degradation. Currently, the clinical efficacy of acotiamide in the population of patients with functional dyspepsia is demonstrated in more than 10 clinical studies in different regions of the world, demonstrating a reduction of the symptoms of the disease during treatment with this agent and an improvement in the quality of life of patients. In addition, the combination of acotiamide with proton pump inhibitors optimizes the management of patients with gastroesophageal reflux disease.

Guidelines on optimizing the use of proton pump inhibitors: PPI stewardship

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.

Efficacy and Safety of Domperidone in Combination with Proton Pump Inhibitors in Gastroesophageal Reflux Disease: A Systematic Review and Meta-Analysis of Randomised Controlled Trials

The aims of gastroesophageal reflux disease (GERD) treatment are symptom relief and healing of oesophagitis. Besides proton pump inhibitors (PPIs), prokinetic agents are also commonly prescribed to treat GERD. Domperidone, a well-known antiemetic, is an example of a prokinetic agent. It is a dopaminergic blocker that increases lower oesophagus sphincter pressure and activates gastric motility. We carried out a systematic review and meta-analysis to explore the benefits of domperidone in addition to PPI therapy for GERD. We searched for publications comparing PPI plus domperidone to PPI monotherapy in terms of symptom improvement in GERD (until 21 April 2022) on PubMed, Scopus, Google Scholar, Web of Science, Cochrane Library, WHO’s International Clinical Studies Registry Platform, and ClinicalTrials.gov without restricting date, language, or study design. The protocol was registered in PROSPERO (CRD42021242076). This meta-analysis incorporated 11 studies with a total of 841 participants (419 in the PPI plus domperidone group and 422 in the PPI monotherapy group). The combination of a PPI and domperidone resulted in a significant reduction in global GERD symptoms. Adverse events associated with PPI plus domperidone treatment were similar to those associated with PPI monotherapy. In conclusion, the combination of domperidone and a PPI is generally safe and effective in treating GERD as compared with that of PPI alone.

Gastroesophageal reflux disease: When East meets West

Gastroesophageal reflux disease (GERD) is common worldwide and poses a huge challenge to health. Consensuses and guidelines on the diagnosis and management of GERD in China and the USA have recently been updated. The divergence between these guidelines indicates the differences in the conception of this disease by experts in different countries, and is influenced by available medications and interventional procedures. Prompt endoscopy has been advocated in China due to a high prevalence of upper gastrointestinal (GI) cancer, while endoscopy has been reserved for those who are at a risk of malignancy or who are reisitant to proton pump inhibitors (PPIs) in the USA. A potassium channel acid-blocker is widely used in Asian countries and has proven efficacy. Moreover, it has been recommended, together with PPIs, as a primary therapy for GERD in China; while PPI alone is recommended as a first-line treatment in the USA. Although more prokinetics are available in China than in the USA and can alleviate GERD symptoms when combined with PPI, the choice of prokinetics is limited in the USA, leading to completely opposite attitudes to prokinetics in the two countries. Novel anti-reflux procedures have been introduced in both countries. Transoral incisionless fundoplication (TIF) is recommended as an endoscopic anti-reflux procedure, and magnetic sphincter augmentation (MSA) is recognized as equivocal to conventional laparoscopic fundoplication in the USA. However, radiofrequency ablation is more popular in China, and clinical trials on TIF and MSA are not complete, which results in diverse opinions about suitable anti-reflux procedures in China. A comparison of the guidelines may therefore shed light on the multiple dimensions of GERD and thus deepen our understanding of the disease.

Gastroesophageal reflux disease: new approaches to optimizing pharmacotherapy

Proton pump inhibitors (PPIs) are baseline drugs for induction and maintenance of remission in gastroesophageal reflux disease (GERD). PPIs have proven to be highly effective in healing esophageal mucosal lesions and relieving the symptoms of the disease in most cases. However, according to the literature data, the incidence rate of clinical ineffectiveness of PPIs in the form of partial or complete persistence of current symptoms during administration of standard doses of PPIs ranges from 10 to 40%. Optimization of GERD therapy in PPI refractory patients is a significant challenge. In most cases, experts advise to increase a dose / dosage frequency of PPIs, switch to CYP2C19-independent PPIs (rabeprazole, esomeprazole, dexlansoprazole), add an esophagoprotective or promotility agents to therapy. At the same time, these recommendations have a limited effect in some patients, which opens up opportunities for looking for new solutions related to the optimization of GERD therapy. Today there is growing evidence of the relevance of the role of disruption of the cytoprotective and barrier properties of the esophageal mucosa in the genesis of GERD and the formation of refractoriness. Intercellular contacts ensure the integrity of the barrier function of the esophageal mucosa to protect it from various exogenous intraluminal substances with detergent properties. Acid-peptic attack in patients with GERD leads to alteration of the expression of some tight junction proteins in epithelial cells of the esophageal mucosa. The latter leads to increased mucosal permeability, which facilitates the penetration of hydrogen ions and other substances into the submucosal layer, where they stimulate the terminals of nerve fibers playing a role in the induction and persistence of the symptoms of the disease. The above evidence brought up to date the effectiveness study of the cytoprotective drugs with tropism to the gastrointestinal tract, as part of the combination therapy of GERD.
