Objective: To study the epidemiological, clinical aspects and factors associated with typical GERD in the general population of Parakou in the Republic of Benin. Methods: This was a descriptive and analytical cross-sectional study with prospective data collection which took place from May 1, 2019 to June 30, 2019. The study population consisted of any subject aged at least 15 years and living in Parakou. Subjects aged at least 15 years, present on the day of the survey and having given their free and informed verbal consent were included. The Short form of QRS®(Reflux-Qual Short form) questionnaire and the “Hospital Anxiety and Depression” score were used to assess the quality of life and anxiety/depression, respectively. The sampling was probabilistic through a 2-stage cluster sampling. The variable of interest was the presence of GERD. Results: Out of 390 subjects surveyed, 28 had symptoms of typical GERD, representing a prevalence of 7.18%. The average age of these subjects was 27.11 ± 7.88 years. Fifteen subjects (53.57%) were male, giving a sex ratio of 1.15. Fourteen (50%) had a secondary level of education, 12 (42.86%) were pupils/students, 18 (64.29%) were single. The monthly income of 22 subjects (78.57%) was lower than the guaranteed interprofessional minimum wage (40,000 FCFA). The average duration of progression of symptoms was 15.89 ± 4.97 months. Symptoms occurred less than twice a week in 22 subjects (78.57%). The clinical manifestations were both diurnal and nocturnal in 12 subjects (42.86%). None of the 28 subjects with GERD had clinical warning signs. Asthma, diabetes, consumption of high fat or spice foods, carbonated drinks, non-steroidal anti-inflammatory drugs, alcoholic beverages and tobacco were statistically associated with the occurrence of GERD. Each of the 28 subjects had at least one associated factor. A significant impair in quality of life was observed in 27 patients (96.43%). Conclusion: Typical GERD is relatively common in the general population of Parakou in the Republic of Benin. It often affects young males. Among the risk factors identified, the most common are carbonated drinks, spicy meals and diabetes. GERD significantly impairs quality of life. Raising awareness about the disease and its associated factors is necessary among the general population.展开更多

Western medicine mainly uses drugs such as proton pump inhibitors to inhibit gastric acid secretion, but some patients are accompanied by symptoms such as non-acid reflux and gas reflux, which cannot effectively treat the disease. It is necessary to actively explore other treatment schemes. Traditional Chinese medicine (TCM) has a long history of research on gastroesophageal reflux disease, which emphasizes the treatment based on syndrome differentiation as a whole. Through the treatment of various and multi-component TCM prescriptions, the patient’s body condition can be adjusted, and the treatment effect on gastroesophageal reflux disease is reliable, which has obvious therapeutic advantages. To further clarify the treatment of gastroesophageal reflux disease, this study reviewed and analyzed the research progress of the treatment of liver disease with modified prescriptions, and the report is as follows.展开更多

The prevalence in China is increasing year by year, which can affect the quality of life of patients and also increase the economic burden on families and society. The pathogenesis of GERD is still unclear, and some studies suggest that intestinal microecology may be closely related to the development of GERD. Rifaximin is not readily absorbed orally and acts locally in the intestine, so it has mild adverse effects and good safety, and can be used to treat gastrointestinal diseases such as irritable bowel syndrome, traveler’s diarrhea, small intestinal bacterial overgrowth, diverticulosis, inflammatory bowel disease and hepatic encephalopathy. Therefore, this paper focuses on intestinal microecology as a possible pathogenesis of GERD and further explores the feasibility of rifaximin for the treatment of GERD.展开更多
文摘BACKGROUND Gastroesophageal reflux disease(GERD)is a common complication of esophageal cancer surgery that can affect quality of life and increase the risk of esophageal stricture and anastomotic leakage.Wendan Decoction(WDD)is a traditional Chinese herbal formula used to treat various gastrointestinal disorders,such as gastritis,functional dyspepsia,and irritable bowel syndrome.Mosapride,a prokinetic agent,functions as a selective 5-hydroxytryptamine 4 agonist,enhancing gastrointestinal motility.AIM To evaluate the therapeutic effects of WDD combined with mosapride on GERD after esophageal cancer surgery.METHODS Eighty patients with GERD were randomly divided into treatment(receiving WDD combined with mosapride)and control(receiving mosapride alone)groups.The treatment was conducted from January 2021 to January 2023.The primary outcome was improved GERD symptoms as measured using the reflux disease questionnaire(RDQ).The secondary outcomes were improved esophageal motility(measured using esophageal manometry),gastric emptying(measured using gastric scintigraphy),and quality of life[measured via the Short Form-36(SF-36)Health Survey].RESULTS The treatment group showed a notably reduced RDQ score and improved esophageal motility parameters,such as lower esophageal sphincter pressure,peristaltic amplitude,and peristaltic velocity compared to the control group.The treatment group showed significantly higher gastric emptying rates and SF-36 scores(in both physical and mental domains)compared to the control group.No serious adverse effects were observed in either group.CONCLUSION WDD combined with mosapride is an effective and safe therapy for GERD after esophageal cancer surgery.It can improve GERD symptoms,esophageal motility,gastric emptying,and the quality of life of patients.Further studies with larger sample sizes and longer follow-up periods are required to confirm these findings.
文摘Achalasia can significantly impair the quality of life.The clinical presentation typically includes dysphagia to both solids and liquids,chest pain,and regurgitation.Diagnosis can be delayed in patients with atypical presentations,and they might receive a wrong diagnosis,such as gastroesophageal reflux disease(GERD),owing to overlapping symptoms of both disorders.Although the cause of achalasia is poorly understood,its impact on the motility of the esophagus and gastroesophageal junction is well established.Several treatment modalities have been utilized,with the most common being surgical Heller myotomy with concomitant fundoplication and pneumatic balloon dilatation.Recently,peroral endoscopic myotomy(POEM)has gained popularity as an effective treatment for achalasia,despite a relatively high incidence of GERD occurring after treatment compared to other modalities.The magnitude of post-POEM GERD depends on its definition and is influenced by patient and procedure-related factors.The longterm sequelae of post-POEM GERD are yet to be determined,but it appears to have a benign course and is usually manageable with clinically available modalities.Identifying risk factors for post-POEM GERD and modifying the POEM procedure in selected patients may improve the overall success of this technique.

文摘BACKGROUND Clinical studies have reported that patients with gastroesophageal reflux disease(GERD)have a higher prevalence of hypertension.AIM To performed a bidirectional Mendelian randomization(MR)analysis to investi-gate the causal link between GERD and essential hypertension.METHODS Eligible single nucleotide polymorphisms(SNPs)were selected,and weighted median,inverse variance weighted(IVW)as well as MR egger(MR-Egger)re-gression were used to examine the potential causal association between GERD and hypertension.The MR-Pleiotropy RESidual Sum and Outlier analysis was used to detect and attempt to reduce horizontal pleiotropy by removing outliers SNPs.The MR-Egger intercept test,Cochran’s Q test and“leave-one-out”sen-sitivity analysis were performed to evaluate the horizontal pleiotropy,heterogen-eities,and stability of single instrumental variable.RESULTS IVW analysis exhibited an increased risk of hypertension(OR=1.46,95%CI:1.33-1.59,P=2.14E-16)in GERD patients.And the same result was obtained in replication practice(OR=1.002,95%CI:1.0008-1.003,P=0.000498).Meanwhile,the IVW analysis showed an increased risk of systolic blood pressure(β=0.78,95%CI:0.11-1.44,P=0.021)and hypertensive heart disease(OR=1.68,95%CI:1.36-2.08,P=0.0000016)in GERD patients.Moreover,we found an decreased risk of Barrett's esophagus(OR=0.91,95%CI:0.83-0.99,P=0.043)in essential hypertension patients.CONCLUSION We found that GERD would increase the risk of essential hypertension,which provided a novel prevent and therapeutic perspectives of essential hypertension.
文摘Achalasia cardia,the most prevalent primary esophageal motility disorder,is predominantly characterized by symptoms of dysphagia and regurgitation.The principal therapeutic approaches for achalasia encompass pneumatic dilatation(PD),Heller's myotomy,and the more recent per-oral endoscopic myotomy(POEM).POEM has been substantiated as a safe and efficacious modality for the management of achalasia.Although POEM demonstrates superior efficacy compared to PD and an efficacy parallel to Heller's myotomy,the incidence of gastroesophageal reflux disease(GERD)following POEM is notably higher than with the aforementioned techniques.While symptomatic reflux post-POEM is relatively infrequent,the significant occurrence of erosive esophagitis and heightened esophageal acid exposure necessitates vigilant monitoring to preclude long-term GERD-related complications.Contemporary advancements in the field have enhanced our comprehension of the risk factors,diagnostic methodologies,preventative strategies,and therapeutic management of GERD subsequent to POEM.This review focuses on the limitations inherent in the 24-h pH study for evaluating post-POEM reflux,potential modifications in the POEM technique to mitigate GERD risk,and the strategies for managing reflux following POEM.

文摘Laryngopharyngeal reflux disease(LPRD)is an inflammatory condition in the laryngopharynx and upper aerodigestive tract mucosa caused by reflux of stomach contents beyond the esophagus.LPRD commonly presents with symptoms such as hoarseness,cough,sore throat,a feeling of throat obstruction,excessive throat mucus.This complex condition is thought to involve both reflux and reflex mechanisms,but a clear understanding of its molecular mechanisms is still lacking.Currently,there is no standardized diagnosis or treatment protocol.Therapeutic strategies for LPRD mainly include lifestyle modifications,proton pump inhibitors and endoscopic surgery.This paper seeks to provide a comprehensive overview of the existing literature regarding the mechanisms,pathophysiology and treatment of LPRD.We also provide an in-depth exploration of the association between LPRD and gastroesophageal reflux disease.
文摘Background:Lifestyle plays an important role in preventing and managing gastroesophageal reflux disease(GERD).In response to the conflicting results in previous studies,we performed a systematic review and meta-analysis to investigate this association.Methods:Relevant studies published until January 2023 were retrieved from 6 databases,and the prevalence of symptomatic gastroesophageal reflux(GER)or GERD was determined from the original studies.A random effects model was employed to meta-analyze the association by computing the pooled relative risk(RR)with 95%confidence intervals(95%CIs).Furthermore,subgroup and dose-response analyses were performed to explore subgroup differences and the association between cumulative physical activity(PA)time and GERD.Results:This meta-analysis included 33 studies comprising 242,850 participants.A significant negative association was observed between PA and the prevalence of symptomatic GER(RR=0.74,95%CI:0.66-0.83;p<0.01)or GERD(RR=0.80,95%CI:0.76-0.84;p<0.01),suggesting that engaging in PA might confer a protective benefit against GERD.Subgroup analyses consistently indicated the presence of this association across nearly all subgroups,particularly among the older individuals(RR_(<40 years):RR_(≥40 years)=0.85:0.69,p<0.01)and smokers(RR_(smoker):RR_(non-smoker)=0.67:0.82,p=0.03).Furthermore,a dose-response analysis revealed that individuals who engaged in 150 min of PA per week had a 72.09%lower risk of developing GERD.Conclusion:Maintaining high levels of PA decreased the risk of GERD,particularly among older adults and smokers.Meeting the recommended PA level of 150 min per week may significantly decrease the prevalence of GERD.
文摘Gastroesophageal reflux disease(GERD)is a prevalent global health concern with a rising incidence.Various risk factors,including obesity,hiatal hernia,and smo-king,contribute to its development.Recent research suggests associations bet-ween GERD and metabolic syndrome,cardiac diseases,and hypertension(HTN).Mechanisms linking GERD to HTN involve autonomic dysfunction,inflammatory states,and endothelial dysfunction.Furthermore,GERD medications such as pro-ton-pump inhibitors may impact blood pressure regulation.Conversely,antihy-pertensive medications like beta-blockers and calcium channel blockers can exacerbate GERD symptoms.While bidirectional causality exists between GERD and HTN,longitudinal studies are warranted to elucidate the precise relationship.Treatment of GERD,including anti-reflux surgery,may positively influence HTN control.However,the interplay of lifestyle factors,comorbidities,and medications necessitates further investigation to comprehensively understand this relation-ship.In this editorial,we comment on the article published by Wei et al in the recent issue of the World Journal of Clinical Cases.We evaluate their claims on the causal association between GERD and HTN.
文摘In this editorial,we respond to a review article by Nabi et al,in which the authors discussed gastroesophageal reflux(GER)following peroral endoscopic myotomy(POEM).POEM is presently the primary therapeutic option for achalasia,which is both safe and effective.A few adverse effects were documented after POEM,including GER.The diagnostic criteria were not clear enough because approximately 60%of patients have a long acid exposure time,while only 10%experience reflux symptoms.Multiple predictors of high disease incidence have been identified,including old age,female sex,obesity,and a baseline lower esophageal sphincter pressure of less than 45 mmHg.Some technical steps during the procedure,such as a lengthy or full-thickness myotomy,may further enhance the risk.Proton pump inhibitors are currently the first line of treatment.Emerging voices are increasingly advocating for the routine combining of POEM with an endoscopic fundoplication method,such as peroral endoscopic fundoplication or transoral incisionless fundoplication.However,more research is necessary to determine the safety and effectiveness of these procedures in the long term for patients who have undergone them.
文摘Introduction: Gastroesophageal reflux disease (GERD) is a benign and chronic disease that can impair the quality of life. Objective: To study the epidemiological, clinical aspects and factors associated with typical GERD in the general population of Parakou in the Republic of Benin. Methods: This was a descriptive and analytical cross-sectional study with prospective data collection which took place from May 1, 2019 to June 30, 2019. The study population consisted of any subject aged at least 15 years and living in Parakou. Subjects aged at least 15 years, present on the day of the survey and having given their free and informed verbal consent were included. The Short form of QRS®(Reflux-Qual Short form) questionnaire and the “Hospital Anxiety and Depression” score were used to assess the quality of life and anxiety/depression, respectively. The sampling was probabilistic through a 2-stage cluster sampling. The variable of interest was the presence of GERD. Results: Out of 390 subjects surveyed, 28 had symptoms of typical GERD, representing a prevalence of 7.18%. The average age of these subjects was 27.11 ± 7.88 years. Fifteen subjects (53.57%) were male, giving a sex ratio of 1.15. Fourteen (50%) had a secondary level of education, 12 (42.86%) were pupils/students, 18 (64.29%) were single. The monthly income of 22 subjects (78.57%) was lower than the guaranteed interprofessional minimum wage (40,000 FCFA). The average duration of progression of symptoms was 15.89 ± 4.97 months. Symptoms occurred less than twice a week in 22 subjects (78.57%). The clinical manifestations were both diurnal and nocturnal in 12 subjects (42.86%). None of the 28 subjects with GERD had clinical warning signs. Asthma, diabetes, consumption of high fat or spice foods, carbonated drinks, non-steroidal anti-inflammatory drugs, alcoholic beverages and tobacco were statistically associated with the occurrence of GERD. Each of the 28 subjects had at least one associated factor. A significant impair in quality of life was observed in 27 patients (96.43%). Conclusion: Typical GERD is relatively common in the general population of Parakou in the Republic of Benin. It often affects young males. Among the risk factors identified, the most common are carbonated drinks, spicy meals and diabetes. GERD significantly impairs quality of life. Raising awareness about the disease and its associated factors is necessary among the general population.
文摘Heartburn is a common symptom shared by both gastroesophageal reflux disease(GERD)and functional heartburn(FHB),which can make it challenging to differentiate between the two conditions.However,examining oral manifestations of GERD can be a cost-effective and readily available method to aid in this differentiation process.It may serve as a valuable tool in distinguishing GERD from FHB.
文摘BACKGROUND In observational studies,dietary intakes are associated with gastroesophageal re-flux disease(GERD).AIM To conduct a two-sample mendelian randomization(MR)analysis to determine whether those associations are causal.METHODS To explore the relationship between dietary intake and the risk of GERD,we extracted appropriate single nucleotide polymorphisms from genome-wide asso-ciation study data on 24 dietary intakes.Three methods were adopted for data analysis:Inverse variance weighting,weighted median methods,and MR-Egger's method.The odds ratio(OR)and 95%confidence interval(CI)were used to eva-luate the causal association between dietary intake and GERD.RESULTS Our univariate Mendelian randomization(UVMR)results showed significant evidence that pork intake(OR,2.83;95%CI:1.76-4.55;P=1.84×10–5),beer intake(OR,2.70,95%CI:2.00-3.64;P=6.54×10–11),non-oily fish intake(OR,2.41;95%CI:1.49-3.91;P=3.59×10–4)have a protective effect on GERD.In addition,dried fruit intake(OR,0.37;95%CI:0.27-0.50;6.27×10–11),red wine intake(OR,0.34;95%CI:0.25-0.47;P=1.90×10-11),cheese intake(OR,0.46;95%CI:0.39-0.55;P=3.73×10-19),bread intake(OR,0.72;95%CI:0.56-0.92;P=0.0009)and cereal intake(OR,0.45;95%CI:0.36-0.57;P=2.07×10-11)were negatively associated with the risk of GERD.There was a suggestive asso-ciation for genetically predicted coffee intake(OR per one SD increase,1.22,95%CI:1.03-1.44;P=0.019).Multi-variate Mendelian randomization further confirmed that dried fruit intake,red wine intake,cheese intake,and cereal intake directly affected GERD.In contrast,the impact of pork intake,beer intake,non-oily fish intake,and bread intake on GERD was partly driven by the common risk factors for GERD.However,after adjusting for all four elements,there was no longer a suggestive association between coffee intake and GERD.CONCLUSION This study provides MR evidence to support the causal relationship between a broad range of dietary intake and GERD,providing new insights for the treatment and prevention of GERD.

文摘BACKGROUND Previous observational studies have shown that the prevalence of gastroesophageal reflux disease(GERD)and Barrett’s esophagus(BE)is associated with socioeconomic status.However,due to the methodological limitations of traditional observational studies,it is challenging to definitively establish causality.AIM To explore the causal relationship between the prevalence of these conditions and socioeconomic status using Mendelian randomization(MR).METHODS We initially screened single nucleotide polymorphisms(SNPs)to serve as proxies for eight socioeconomic status phenotypes for univariate MR analysis.The inverse variance weighted(IVW)method was used as the primary analytical method to estimate the causal relationship between the eight socioeconomic status phenotypes and the risk of GERD and BE.We then collected combinations of SNPs as composite proxies for the eight socioeconomic phenotypes to perform multivariate MR(MVMR)analyses based on the IVW MVMR model.Furthermore,a two-step MR mediation analysis was used to examine the potential mediation of the associations by body mass index,major depressive disorder(MDD),smoking,alcohol consumption,and sleep duration.RESULTS The study identified three socioeconomic statuses that had a significant impact on GERD.These included household income[odds ratio(OR):0.46;95% confidence interval(95%CI):0.31-0.70],education attainment(OR:0.23;95%CI:0.18-0.29),and the Townsend Deprivation Index at recruitment(OR:1.57;95%CI:1.04-2.37).These factors were found to independently and predominantly influence the genetic causal effect of GERD.Furthermore,the mediating effect of educational attainment on GERD was found to be mediated by MDD(proportion mediated:10.83%).Similarly,the effect of educational attainment on BE was mediated by MDD(proportion mediated:10.58%)and the number of cigarettes smoked per day(proportion mediated:3.50%).Additionally,the mediating effect of household income on GERD was observed to be mediated by sleep duration(proportion mediated:9.75%)CONCLUSION This MR study shed light on the link between socioeconomic status and GERD or BE,providing insights for the prevention of esophageal cancer and precancerous lesions.
文摘BACKGROUND Most endoscopic anti-reflux interventions for gastroesophageal reflux disease(GERD)management are technically challenging to practice with inadequate data to support it utility.Therefore,this study was carried to evaluate the effectiveness and safety newer endoscopic full-thickness fundoplication(EFTP)device along with Argon Plasma Coagulation to treat individuals with GERD.AIM To evaluate the effectiveness and safety newer EFTP device along with Argon Plasma Coagulation to treat individuals with GERD.METHODS This study was a single-center comparative analysis conducted on patients treated at a Noble Institute of Gastroenterology,Ahmedabad,hospital between 2020 and 2022.The research aimed to retrospectively analyze patient data on GERD symptoms and proton pump inhibitor(PPI)dependence who underwent EFTP using the GERD-X system along with argon plasma coagulation(APC).The primary endpoint was the mean change in the total gastroesophageal reflux disease health-related quality of life(GERD-HRQL)score compared to the baseline measurement at the 3-month follow-up.Secondary endpoints encompassed enhancements in the overall GERD-HRQL score,improvements in GERD symptom scores at the 3 and changes in PPI usage at the 3 and 12-month time points.RESULTS In this study,patients most were in Hill Class II,and over half had ineffective esophageal motility.Following the EFTP procedure,there were significant improvements in heartburn and regurgitation scores,as well as GERDHRQL scores(P<0.001).PPI use significantly decreased,with 82.6%not needing PPIs or prokinetics at end of 1 year.No significant adverse events related to the procedures were observed in either group.CONCLUSION The EFTP along with APC procedure shows promise in addressing GERD symptoms and improving patients'quality of life,particularly for suitable candidates.Moreover,the application of a lone clip with APC yielded superior outcomes and exhibited greater cost-effectiveness.
文摘Gastroesophageal reflux disease (GERD) is a high-incidence digestive system disease. Western medicine mainly uses drugs such as proton pump inhibitors to inhibit gastric acid secretion, but some patients are accompanied by symptoms such as non-acid reflux and gas reflux, which cannot effectively treat the disease. It is necessary to actively explore other treatment schemes. Traditional Chinese medicine (TCM) has a long history of research on gastroesophageal reflux disease, which emphasizes the treatment based on syndrome differentiation as a whole. Through the treatment of various and multi-component TCM prescriptions, the patient’s body condition can be adjusted, and the treatment effect on gastroesophageal reflux disease is reliable, which has obvious therapeutic advantages. To further clarify the treatment of gastroesophageal reflux disease, this study reviewed and analyzed the research progress of the treatment of liver disease with modified prescriptions, and the report is as follows.

文摘BACKGROUND Currently,the primary treatment for gastroesophageal reflux is acid suppression with proton pump inhibitors,but they are not a cure,and some patients don’t respond well or refuse long-term use.Therefore,alternative therapies are needed to understand the disease and develop better treatments.Laparoscopic anti-reflux surgery(LARS)can resolve symptoms of these patients and plays a significant role in evaluating esophageal healing after preventing harmful effects.Successful LARS improves typical gastroesophageal reflux symptoms in most patients,main-ly by reducing the exposure time to gastric contents in the esophagus.Amelio-ration of the inflammatory response and a recovery response in the esophageal epithelium is expected following the cessation of the noxious attack.AIM To explore the role of inflammatory biomolecules in LARS and assess the time required for esophageal epithelial recovery.METHODS Of 22 patients with LARS(pre-and post/5.8±3.8 months after LARS)and 25 healthy controls(HCs)were included.All subjects underwent 24-h multichannel intraluminal impedance-pH monitoring and upper gastrointestinal endoscopy,during which esophageal biopsy samples were collected using endoscopic tech-niques.Inflammatory molecules in esophageal biopsies were investigated by reverse transcription-polymerase chain reaction and multiplex-enzyme-linked immunosorbent assay.RESULTS Post-LARS samples showed significant increases in proinflammatory cytokines[interleukin(IL)-1β,interferon-γ,C-X-C chemokine ligand 2(CXCL2)],anti-inflammatory cytokines[CC chemokine ligand(CCL)11,CCL13,CCL17,CCL26,CCL1,CCL7,CCL8,CCL24,IL-4,IL-10],and homeostatic cytokines(CCL27,CCL20,CCL19,CCL23,C-CL25,CXCL12,migration inhibitory factor)compared to both HCs and pre-LARS samples.CCL17 and CCL21 levels were higher in pre-LARS than in HCs(P<0.05).The mRNA expression levels of AKT1,fibroblast growth factor 2,HRAS,and mitogen-activated protein kinase 4 were significantly decreased post-LARS vs pre-LARS.CCL2 and epidermal growth factor gene levels were significantly increased in the pre-LARS compared to the HCs(P<0.05).CONCLUSION The presence of proinflammatory proteins post-LARS suggests ongoing inflammation in the epithelium.Elevated homeostatic cytokine levels indicate cell balance is maintained for about 6 months after LARS.The anti-inflam-matory response post-LARS shows suppression of inflammatory damage and ongoing postoperative recovery.

文摘BACKGROUND Gastroesophageal reflux disease(GERD)affects approximately 13% of the global population.However,the pathogenesis of GERD has not been fully elucidated.The development of metabolomics as a branch of systems biology in recent years has opened up new avenues for the investigation of disease processes.As a powerful statistical tool,Mendelian randomization(MR)is widely used to explore the causal relationship between exposure and outcome.AIM To analyze of the relationship between 486 blood metabolites and GERD.METHODS Two-sample MR analysis was used to assess the causal relationship between blood metabolites and GERD.A genome-wide association study(GWAS)of 486 metabolites was the exposure,and two different GWAS datasets of GERD were used as endpoints for the base analysis and replication and meta-analysis.Bonferroni correction is used to determine causal correlation features(P<1.03×10^(-4)).The results were subjected to sensitivity analysis to assess heterogeneity and pleiotropy.Using the MR Steiger filtration method to detect whether there is a reverse causal relationship between metabolites and GERD.In addition,metabolic pathway analysis was conducted using the online database based MetaboAnalyst 5.0 software.RESULTS In MR analysis,four blood metabolites are negatively correlated with GERD:Levulinate(4-oxovalerate),stearate(18:0),adrenate(22:4n6)and p-acetamidophenylglucuronide.However,we also found a positive correlation between four blood metabolites and GERD:Kynurenine,1-linoleoylglycerophosphoethanolamine,butyrylcarnitine and guanosine.And bonferroni correction showed that butyrylcarnitine(odd ratio 1.10,95% confidence interval:1.05-1.16,P=7.71×10^(-5))was the most reliable causal metabolite.In addition,one significant pathways,the"glycerophospholipid metabolism"pathway,can be involved in the pathogenesis of GERD.CONCLUSION Our study found through the integration of genomics and metabolomics that butyrylcarnitine may be a potential biomarker for GERD,which will help further elucidate the pathogenesis of GERD and better guide its treatment.At the same time,this also contributes to early screening and prevention of GERD.However,the results of this study require further confirmation from both basic and clinical real-world studies.

文摘Gastroesophageal reflux(GER)in children is very common and refers to the involuntary passage of gastric contents into the esophagus.This is often physiological and managed conservatively.In contrast,GER disease(GERD)is a less common pathologic process causing troublesome symptoms,which may need medical management.Apart from abnormal transient relaxations of the lower esophageal sphincter,other factors that play a role in the pathogenesis of GERD include defects in esophageal mucosal defense,impaired esophageal and gastric motility and clearance,as well as anatomical defects of the lower esophageal reflux barrier such as hiatal hernia.The clinical manifestations of GERD in young children are varied and nonspecific prompting the necessity for careful diagnostic evaluation.Management should be targeted to the underlying aetiopathogenesis and to limit complications of GERD.The following review focuses on up-to-date information regarding of the pathogenesis,diagnostic evaluation and management of GERD in children.
文摘BACKGROUND Gastroesophageal reflux is associated with poorer outcomes after lung transplant,likely through recurrent aspiration and allograft injury.Although prior studies have demonstrated a relationship between impedance-pH results and transplant outcomes,the role of esophageal manometry in the assessment of lung transplant patients remains debated,and the impact of esophageal dysmotility on transplant outcomes is unclear.Of particular interest is ineffective esophageal motility(IEM)and its associated impact on esophageal clearance.AIM To assess the relationship between pre-transplant IEM diagnosis and acute rejection after lung transplantation.METHODS This was a retrospective cohort study of lung transplant recipients at a tertiary care center between 2007 and 2018.Patients with pre-transplant anti-reflux surgery were excluded.Manometric and reflux diagnoses were recorded from pre-transplant esophageal function testing.Time-to-event analysis using Cox proportional hazards model was applied to evaluate outcome of first episode of acute cellular rejection,defined histologically per International Society of Heart and Lung Transplantation guidelines.Subjects not meeting this endpoint were censored at time of post-transplant anti-reflux surgery,last clinic visit,or death.Fisher’s exact test for binary variables and student’s t-test for continuous variables were performed to assess for differences between groups.RESULTS Of 184 subjects(54%men,mean age:58,follow-up:443 person-years)met criteria for inclusion.Interstitial pulmonary fibrosis represented the predominant pulmonary diagnosis(41%).During the follow-up period,60 subjects(33.5%)developed acute rejection.The all-cause mortality was 16.3%.Time-to-event univariate analyses demonstrated significant association between IEM and acute rejection[hazard ratio(HR):1.984,95%CI:1.03-3.30,P=0.04],confirmed on Kaplan-Meier curve.On multivariable analysis,IEM remained independently associated with acute rejection,even after controlling for potential confounders such as the presence of acid and nonacid reflux(HR:2.20,95%CI:1.18-4.11,P=0.01).Nonacid reflux was also independently associated with acute rejection on both univariate(HR:2.16,95%CI:1.26-3.72,P=0.005)and multivariable analyses(HR:2.10,95%CI:1.21-3.64,P=0.009),adjusting for the presence of IEM.CONCLUSION Pre-transplant IEM was associated with acute rejection after transplantation,even after controlling for acid and nonacid reflux.Esophageal motility testing may be considered in lung transplant to predict outcomes.

文摘BACKGROUND Heartburn is identically the key symptom of both,gastroesophageal reflux disease(GERD)and functional heartburn(FHB),making the differential diagnosis resource-intensive.Oral manifestations of GERD can be easily examined;therefore,their exploration might be a cheap,widely available,and useful tool in the differentiation of GERD and FHB.AIM To evaluate the prevalence of dental erosions(DE)and periodontal diseases(PD)in patients with heartburn and their association with GERD and FHB.METHODS A total of 116[M/F:51/65,mean age:54(17-80)years]consecutive patients with heartburn were enrolled for detailed esophageal function and orodental examinations.RESULTS Dental disorders were detected in 89%(103/116).Patients with PD+DE had significantly more often pathologic reflux(90.0%vs 27.8%;P<0.05),higher esophagitis scores(1.8 vs 0.9;P<0.05),and a significantly different mean impedance curve(P=0.04)than those without any dental diseases.The opposite approach established that patients with GERD had significantly higher prevalence of DE and PD,especially if both were present(28.9%vs 2.0%;P<0.01),more severe PD(1.5 vs 1.0;P<0.01),and longer history of heartburn(15 years vs 9 years;P<0.01)than those with FHB.CONCLUSION The dental evaluation of patients with heartburn seems to be useful in the differential diagnosis of GERD and FHB.Among the studied parameters,the co-appearance of DE and PD seems to be the best predictor of GERD,whereas the absence of dental disorders was mostly observed in FHB.
文摘Rifaximin in the Treatment of Gastroesophageal Reflux Disease (GERD) is a common clinical disorder, the most common symptom of which is a burning sensation behind the breastbone (heartburn) or reflux of stomach contents into the upper pharynx (acid reflux). The prevalence in China is increasing year by year, which can affect the quality of life of patients and also increase the economic burden on families and society. The pathogenesis of GERD is still unclear, and some studies suggest that intestinal microecology may be closely related to the development of GERD. Rifaximin is not readily absorbed orally and acts locally in the intestine, so it has mild adverse effects and good safety, and can be used to treat gastrointestinal diseases such as irritable bowel syndrome, traveler’s diarrhea, small intestinal bacterial overgrowth, diverticulosis, inflammatory bowel disease and hepatic encephalopathy. Therefore, this paper focuses on intestinal microecology as a possible pathogenesis of GERD and further explores the feasibility of rifaximin for the treatment of GERD.
