Despite the availability of this workup in Benin Republic, there is a scarcity of data on chronic gastritis. Objective: This work aimed to study the epidemiological and histopathological aspects of chronic gastritis in the Departmental University Teaching Hospital of Borgou Alibori (CHUD-B/A) from 2011 to 2021. Method: This was a retrospective cross-sectional study with descriptive and analytical purposes, carried out from February 23, 2022 to May 23, 2022, among patients who had undergone gastric biopsy and/or gastrectomy from January 2011 to January 2022 (10 year), and whose specimens were sent into the histopathology section of the CHUD-B/A. Non-probability sampling was performed with exhaustive recruitment. A survey form has been used to collect data from patients’ medical records. Pearson’s chi-square and Fisher’s exact tests have been used as appropriate to determine correlations between variables. Result: A total of 310 cases of chronic gastritis were diagnosed in the histopathology section of the CHUD-B/A from 2011 to 2021. This represented a chronic gastritis frequency of 91.45% for all gastric lesions diagnosed throughout the study period. Erythematous gastropathy was the most frequent (70.35%). Helicobacter pylori was present in 36.77% and dysplasia was observed in 12.26% of cases. Erythematous gastropathy was a predictive factor for the absence of gastric dysplasia in histopathology check up (p-value = 0.042). In contrast, intestinal metaplasia was predictive of the presence of gastric dysplasia in histopathology check up (p-value < 0.001). Conclusion: Chronic gastritis is very common in our setting. Systematic biopsy performance in front of an evocative clinical situation followed by histopathological examination may be encouraged.展开更多

Shenling-bai-zhu san(SLBZS), a traditional Chinese medicine formula, is widely used for treating CG. Nevertheless, its effects are currently unclear.AIM To determine the clinical evidence and potential mechanisms of SLBZS for the treatment of CG.METHODS We systematically searched 3 English(PubMed, Embase, Medline) and 4 Chinese databases(Cochrane Library Central Register of Controlled Trials, China National Knowledge Infrastructure database, Wanfang Data Knowledge Service Platform,and the VIP information resource integration service platform) without language or publication bias restriction. Qualified studies were selected according to pre-set inclusion and exclusion criteria. RevMan 5.3 software was used for meta-analysis and literature quality assessment, Stata 14.0 software was used for sensitivity analysis, GRADE profiler 3.6 was used to evaluate the quality of evidence. And then, network pharmacology analysis was applied to primary research the mechanisms of action of SLBZS on CG.RESULTS Fourteen studies were finally included, covering 1335 participants. Meta-analysis indicated that:(1) SLBZS was superior to conventional therapies [risk ratio(RR):1.29, 95% confidence interval(CI): 1.21 to 1.37, P < 0.00001];(2) SLBZS was better than conventional therapies [RR: 0.24, 95% confidence interval(95%CI): 0.11 to 0.55, P = 0.0007] in terms of recurrence rate and reversal of Helicobacter pylori positivity(RR: 1.20, 95%CI: 1.11 to 1.30,P < 0.00001);and(3) The safety of SLBZS for CG remains unclear. According to the GRADE method, the quality of evidence was not high. Besides, SNZJS might treat CG by acting on related targets and pathways such as EGFR tyrosine kinase inhibitor resistance, the PI3K-Akt signaling pathway, and others.CONCLUSION SLBZS might be useful in treating CG, but long-term effects and specific clinical mechanisms of it maintain unclear. More samples and high-quality clinical experiments should be assessed and verified in the next step.展开更多

We hypothesize that IM is correlated with the intensity of H. pylori infection in a country with high endemicity, Ivory Coast. The objective of this study was to determine the prevalence of intestinal metaplasia in chronic H. pylori gastritis in Ivory Coast. Methods: This was a prospective, cross-sectional, multicenter study, carried out over a period of 5 months, in the reference hospital centers of Abidjan, specialized in Gastroenterology. All patients who had undergone Gastroscopy with biopsies according to the criteria of the Sydney System for the anatomopathological study, those with chronic gastritis and/or H. pylori intestinal metaplasia on histology and in whom all the parameters of the Sydney system classification had been well informed. The quantitative variables were expressed by their means accompanied by their standard deviations and the qualitative variables by their numbers and percentages. Chi-square and Fischer tests were used to look for associations between variables. The significance level was set at 5%. Results: 152 patients were retained. The mean age was 44.9 ± 12.9 years. The prevalence of intestinal metaplasia was 11.8%. In univariate analysis, no significant association was found between clinical and pathological sociodemographic factors (age, sex, ethnicity, educational level, profession) and intestinal metaplasia in chronic Helicobacter pylori gastric cases. In multivariate analysis we found that prolonged use of Proton Pump Inhibitors (PPIs) and a history of Gastroesophageal Reflux Disease (GERD) were significantly associated with the absence of IM. Conclusion: Chronic H. pylori gastritis is the main risk factor for intestinal metaplasia. Prolonged use of PPIs and a history of GERD were significantly identified as factors that would protect against intestinal metaplasia.展开更多

A commonly-seen disease in clinical practice, it is found in about 80%-90% of patients undergoing gastroscopic examination. The prevalence rate in the general population remains unclear. It is generally considered that its incidence rate accords with Helicobacter. pylori infection rate and the prevalence of CG is 30%-80% in China. Possible etiological factors include H. pylori infection, smoking, drinking alcohol, food allergies, duodenal juice reflux, drug-induced injuries, heredity, immunity, and radiation.^[1-8].展开更多

This suggests that ICAM-1 is related to the local immunological tolerence of gastriccarcinoma.展开更多

文摘BACKGROUND Helicobacter pylori(H.pylori)infection is a major risk factor for chronic gastritis,affecting approximately half of the global population.H.pylori eradication is a popular treatment method for H.pylori-positive chronic gastritis,but its mecha-nism remains unclear.Urinary metabolomics has been used to elucidate the mechanisms of gastric disease treatment.However,no clinical study has been conducted on urinary metabolomics of chronic gastritis.AIM To elucidate the urinary metabolic profiles during H.pylori eradication in patients with chronic gastritis.METHODS We applied LC–MS-based metabolomics and network pharmacology to in-vestigate the relationships between urinary metabolites and H.pylori-positive chronic gastritis via a clinical follow-up study.RESULTS Our study revealed the different urinary metabolic profiles of H.pylori-positive chronic gastritis before and after H.pylori eradication.The metabolites regulated by H.pylori eradication therapy include cis-aconitic acid,isocitric acid,citric acid,L-tyrosine,L-phenylalanine,L-tryptophan,and hippuric acid,which were involved in four metabolic pathways:(1)Phenylalanine metabolism;(2)phenylalanine,tyrosine,and tryptophan biosynthesis;(3)citrate cycle;and(4)glyoxylate and dicarboxylate metabolism.Integrated metabolomics and network pharmacology revealed that MPO,COMT,TPO,TH,EPX,CMA1,DDC,TPH1,and LPO were the key proteins involved in the biological progress of H.pylori eradication in chronic gastritis.CONCLUSION Our research provides a new perspective for exploring the significance of urinary metabolites in evaluating the treatment and prognosis of H.pylori-positive chronic gastritis patients.
文摘Currently,the diagnostic strategy for chronic gastritis(CG)is aimed not just at fixing the presence of gastric mucosal inflammation,but also at gastric cancer(GC)risk stratification in a particular patient.Modern classification approach with the definition of the stage of gastritis determines the need,activities and frequency of dynamic monitoring of a patient.However,this attitude to the patient suffering from CG was far from always.The present publication is a literature review describing the key milestones in the history of CG research,from the description of the first observations of inflammation of the gastric mucosa,assessment of gastritis as a predominantly functional disease,to the advent of endoscopy of the upper digestive tract and diagnostic gastric biopsy,assessment of the role of Helicobacter pylori infection in progression of inflammatory changes to atrophy,intestinal metaplasia,dysplasia and GC.
文摘Chronic gastritis is the persistent and insidious inflammation of the gastric lining.Helicobacter pylori(H.pylori)has been identified as the most common cause of chronic gastritis and consequently elimination of H.pylori can lead to its cure.This editorial explores the use of urinary metabolic profiles before and after eradication to identify biomarkers that can aid in prognosis and treatment.Despite providing promising insights,there are limitations such as a small sample size(17 patients),a narrow treatment period of 2 wk,and treatment heterogeneity,which raise concerns.Nevertheless,these findings have opened a gateway to enhancing the treatment and prognosis of chronic gastritis through urinary metabolomics.
文摘BACKGROUND Chronic gastritis(CG)is a common gastrointestinal disorder characterized by inflammation of the stomach lining.Liver-stomach disharmony(LSD)syndrome is believed to contribute to CG symptoms.AIM To evaluate the efficacy and safety of microcosmic syndrome differentiation and Chinese herbal medicine(CHM)treatment in patients with CG and LSD syndrome.METHODS Sixty-four patients with CG and LSD syndrome were randomly divided into two groups:The treatment group received CHM based on microcosmic syndrome differentiation and the control group received conventional Western medicine.The treatment course lasted 12 wk.The primary outcome was improvement in dyspeptic symptoms,measured using the Nepean Dyspepsia Index.The secondary outcomes included the improvement rate of endoscopic findings,histopathological findings,and microcosmic syndrome scores and the incidence of adverse events.RESULTS After 12 wk of treatment,the treatment group showed significantly greater improvement in dyspeptic symptoms than the control group(93.75%vs 65.63%,P<0.01).The treatment group also showed a significantly higher improvement rate in endoscopic findings than the control group(81.25%vs 53.13%,P<0.05).The improvement rates of histopathological findings and microcosmic syndrome scores were not significantly different between the two groups(P>0.05).No serious adverse events were observed in either group.CONCLUSION Microcosmic syndrome differentiation and CHM treatment can effectively improve dyspeptic symptoms and endoscopic findings in patients with CG and LSD syndrome and have a good safety profile.Further studies with larger sample sizes and longer follow-up periods are required to confirm the long-term efficacy and mechanism of action of this treatment.
文摘Background: Gastritis is better evaluated nowadays since the advent of upper gastrointestinal endoscopy. Despite the availability of this workup in Benin Republic, there is a scarcity of data on chronic gastritis. Objective: This work aimed to study the epidemiological and histopathological aspects of chronic gastritis in the Departmental University Teaching Hospital of Borgou Alibori (CHUD-B/A) from 2011 to 2021. Method: This was a retrospective cross-sectional study with descriptive and analytical purposes, carried out from February 23, 2022 to May 23, 2022, among patients who had undergone gastric biopsy and/or gastrectomy from January 2011 to January 2022 (10 year), and whose specimens were sent into the histopathology section of the CHUD-B/A. Non-probability sampling was performed with exhaustive recruitment. A survey form has been used to collect data from patients’ medical records. Pearson’s chi-square and Fisher’s exact tests have been used as appropriate to determine correlations between variables. Result: A total of 310 cases of chronic gastritis were diagnosed in the histopathology section of the CHUD-B/A from 2011 to 2021. This represented a chronic gastritis frequency of 91.45% for all gastric lesions diagnosed throughout the study period. Erythematous gastropathy was the most frequent (70.35%). Helicobacter pylori was present in 36.77% and dysplasia was observed in 12.26% of cases. Erythematous gastropathy was a predictive factor for the absence of gastric dysplasia in histopathology check up (p-value = 0.042). In contrast, intestinal metaplasia was predictive of the presence of gastric dysplasia in histopathology check up (p-value < 0.001). Conclusion: Chronic gastritis is very common in our setting. Systematic biopsy performance in front of an evocative clinical situation followed by histopathological examination may be encouraged.
文摘BACKGROUND Chronic gastritis(CG) is an inflammatory disease of the gastric mucosa. Shenling-bai-zhu san(SLBZS), a traditional Chinese medicine formula, is widely used for treating CG. Nevertheless, its effects are currently unclear.AIM To determine the clinical evidence and potential mechanisms of SLBZS for the treatment of CG.METHODS We systematically searched 3 English(PubMed, Embase, Medline) and 4 Chinese databases(Cochrane Library Central Register of Controlled Trials, China National Knowledge Infrastructure database, Wanfang Data Knowledge Service Platform,and the VIP information resource integration service platform) without language or publication bias restriction. Qualified studies were selected according to pre-set inclusion and exclusion criteria. RevMan 5.3 software was used for meta-analysis and literature quality assessment, Stata 14.0 software was used for sensitivity analysis, GRADE profiler 3.6 was used to evaluate the quality of evidence. And then, network pharmacology analysis was applied to primary research the mechanisms of action of SLBZS on CG.RESULTS Fourteen studies were finally included, covering 1335 participants. Meta-analysis indicated that:(1) SLBZS was superior to conventional therapies [risk ratio(RR):1.29, 95% confidence interval(CI): 1.21 to 1.37, P < 0.00001];(2) SLBZS was better than conventional therapies [RR: 0.24, 95% confidence interval(95%CI): 0.11 to 0.55, P = 0.0007] in terms of recurrence rate and reversal of Helicobacter pylori positivity(RR: 1.20, 95%CI: 1.11 to 1.30,P < 0.00001);and(3) The safety of SLBZS for CG remains unclear. According to the GRADE method, the quality of evidence was not high. Besides, SNZJS might treat CG by acting on related targets and pathways such as EGFR tyrosine kinase inhibitor resistance, the PI3K-Akt signaling pathway, and others.CONCLUSION SLBZS might be useful in treating CG, but long-term effects and specific clinical mechanisms of it maintain unclear. More samples and high-quality clinical experiments should be assessed and verified in the next step.

文摘BACKGROUND Innate immunity was found to be associated with both persistence of Helicobacter pylori(H.pylori)infection and increased risk of gastric cancer.AIM To identify the risk factors associated with H.pylori infection and to establish the role of TLR9 rs352140 in suppressing or promoting inflammation related to this infection in children.METHODS We performed a study of 155 children with digestive symptoms,who were divided into two groups according to the histopathological exam:Group 1–48 children with H.pylori-induced chronic gastritis,and Group 2–control group.RESULTS Rural area and poor living conditions were significantly associated with H.pylori chronic gastritis(P=0.0042/P<0.0001).Both positive immunoglobulin A anti H.pylori and the rapid urease test were significantly associated with H.pylori infection(P<0.0001).Significantly higher values of leukocytes and neutrophils within the peripheral blood were found in children with H.pylori chronic gastritis(P=0.111/P=0.284).We found a significant positive correlation between the variant TT genotype of TLR9 rs352140 polymorphism and both leucocytes and neutrophils(P=0.0225/P=0.0292).CONCLUSION Variant TT genotype carriers of the TLR9 rs352140 gene polymorphism might have a more severe degree of inflammation.
文摘AIM:To evaluate fecal calprotectin concentrations(FCCs) in subjects with chronic gastritis and the correlation between FCCs and gastritis activity score.METHODS:FCCs were measured in 61 patients with histological diagnosis of gastritis and in 74 healthy volunteers.Histological grading of gastritis was performed according to the updated Sydney gastritis classification.Patients were subdivided into 2 groups according to the presence/absence of an active gastritis.Patients with chronic active gastritis were divided into 3 subgroups on the basis of the activity score(mild,moderate,marked).FFCs in relation to Helicobacter pylori(H.pylori) infection and proton pump inhibitor(PPI) use were also evaluated.RESULTS:FCCs in patients with chronic active gastritis were not significantly different to FCCs either in subjects with non active gastritis or in healthy controls.Among patients with chronic active gastritis(even marked),FCCs did not significantly differ according to activity score.No significant differences in FCCs were found when considering H.pylori,as well as when considering PPI chronic use.CONCLUSION:FCCs were not significantly increased in subjects with chronic gastritis,even in those patients with a marked neutrophil infiltration.

文摘BACKGROUND Although chronic erosive gastritis(CEG)is common,its clinical characteristics have not been fully elucidated.The lack of consensus regarding its treatment has resulted in varied treatment regimens.AIM To explore the clinical characteristics,treatment patterns,and short-term outcomes in CEG patients in China.METHODS We recruited patients with chronic non-atrophic or mild-to-moderate atrophic gastritis with erosion based on endoscopy and pathology.Patients and treating physicians completed a questionnaire regarding history,endoscopic findings,and treatment plans as well as a follow-up questionnaire to investigate changes in symptoms after 4 wk of treatment.RESULTS Three thousand five hundred sixty-three patients from 42 centers across 24 cities in China were included.Epigastric pain(68.0%),abdominal distension(62.6%),and postprandial fullness(47.5%)were the most common presenting symptoms.Gastritis was classified as chronic non-atrophic in 69.9%of patients.Among those with erosive lesions,72.1%of patients had lesions in the antrum,51.0%had multiple lesions,and 67.3%had superficial flat lesions.In patients with epigastric pain,the combination of a mucosal protective agent(MPA)and proton pump inhibitor was more effective.For those with postprandial fullness,acid regurgitation,early satiety,or nausea,a MPA appeared more promising.CONCLUSION CEG is a multifactorial disease which is common in Asian patients and has non-specific symptoms.Gastroscopy may play a major role in its detection and diagnosis.Treatment should be individualized based on symptom profile.
文摘Gastric cystica profunda(GCP)is an uncommon but underestimated gastric lesion.Its precancerous potential determines its significance.In addition to previous mucosa injury due to operations,biopsy or polypectomy,chronic active and atrophic gastritis may also lead to the development of GCPs.By carefully examining the stomach and taking biopsy samples from the susceptible regions,the stage of atrophy can be determined.Chronic atrophic gastritis is a risk factor for cancer evolvement and it can also contribute to GCPs formation.GCPs frequently occur close to early gastric cancers(EGCs)or EGC can arise from the cystic glands.Endoscopic resection is an effective and minimally invasive treat-ment in GCP.

文摘BACKGROUND The Correa sequence,initiated by Helicobacter pylori(H.pylori),commonly progresses to gastric cancer through the stage of chronic atrophic gastritis(CAG).Although eradication of H.pylori only reduces the risk of gastric cancer,it does not eliminate the risk for neoplastic progression.Yiwei Xiaoyu granules(YWXY)are a commonly used composite preparation in Chinese clinics.However,the pursuit of excellence in clinical trials and the establishment of standardized animal experiments are still needed to contribute to full understanding and application of traditional Chinese medicine in the treatment of CAG.AIM To demonstrate the effectiveness of YWXY in patients with CAG and spleenstomach deficiency syndrome(DSSS),by alleviating histological scores,improving response rates for pathological lesions,and achieving clinical efficacy in relieving DSSS symptoms.METHODS We designed a double-blind,randomized,controlled trial.The study enrolled seventy-two H.pylori-negative patients(mean age,52.3 years;38 men)who were randomly allocated to either the treatment group or control group in a 1:1 ratio,and treated with 15 g YWXY or 0.36 g Weifuchun(WFC)tablet combined with the respective dummy for 24 wk.The pre-randomization phase resulted in the exclusion of 72 patients:50 participants did not meet the inclusion criteria,12 participants declined to participate,and 10 participants were excluded for various other reasons.Seven visits were conducted during the study,and histopathological examination with target endoscopic biopsy of narrow-band imaging was requested before the first and seventh visits.We also evaluated endoscopic performance scores,total symptom scores,serum pepsinogen and gastrin-17.RESULTS Six patients did not complete the trial procedures.Treatment with YWXY improved the Operative Link on Gastric Intestinal Metaplasia Assessment(OLGIM)stage,compared with WFC(P<0.05).YWXY provided better relief from symptoms of DSSS and better improvement in serum gastric function,compared with WFC(P<0.05).CONCLUSION YWXY compared with WFC significantly reduced the risk of mild or moderate atrophic disease,according to OLGIM stage,significantly relieved symptoms of DSSS,and improved serum gastric function.

文摘BACKGROUND The Chinese medicine Yangyin Huowei mixture(YYHWM)exhibits good clinical efficacy in the treatment of chronic atrophic gastritis(CAG),but the mechanisms underlying its activity remain unclear.AIM To investigate the therapeutic effects of YYHWM and its underlying mechanisms in a CAG rat model.METHODS Sprague-Dawley rats were allocated into control,model,vitacoenzyme,and low,medium,and high-dose YYHWM groups.CAG was induced in rats using Nmethyl-N′-nitro-N-nitrosoguanidine,ranitidine hydrochloride,hunger and satiety perturbation,and ethanol gavage.Following an 8-wk intervention period,stomach samples were taken,stained,and examined for histopathological changes.ELISA was utilized to quantify serum levels of PG-I,PG-II,G-17,IL-1β,IL-6,and TNF-α.Western blot analysis was performed to evaluate protein expression of IL-10,JAK1,and STAT3.RESULTS The model group showed gastric mucosal layer disruption and inflammatory cell infiltration.Compared with the blank control group,serum levels of PGI,PGII,and G-17 in the model group were significantly reduced(82.41±3.53 vs 38.52±1.71,23.06±0.96 vs 11.06±0.70,and 493.09±12.17 vs 225.52±17.44,P<0.01 for all),whereas those of IL-1β,IL-6,and TNF-αwere significantly increased(30.15±3.07 vs 80.98±4.47,69.05±12.72 vs 110.85±6.68,and 209.24±11.62 vs 313.37±36.77,P<0.01 for all),and the protein levels of IL-10,JAK1,and STAT3 were higher in gastric mucosal tissues(0.47±0.10 vs 1.11±0.09,0.49±0.05 vs 0.99±0.07,and 0.24±0.05 vs 1.04±0.14,P<0.01 for all).Compared with the model group,high-dose YYHWM treatment significantly improved the gastric mucosal tissue damage,increased the levels of PGI,PGII,and G-17(38.52±1.71 vs 50.41±3.53,11.06±0.70 vs 15.33±1.24,and 225.52±17.44 vs 329.22±29.11,P<0.01 for all),decreased the levels of IL-1β,IL-6,and TNF-α(80.98±4.47 vs 61.56±4.02,110.85±6.68 vs 89.20±8.48,and 313.37±36.77 vs 267.30±9.31,P<0.01 for all),and evidently decreased the protein levels of IL-10 and STAT3 in gastric mucosal tissues(1.11±0.09 vs 0.19±0.07 and 1.04±0.14 vs 0.55±0.09,P<0.01 for both).CONCLUSION YYHWM reduces the release of inflammatory factors by inhibiting the IL-10/JAK1/STAT3 pathway,alleviating gastric mucosal damage,and enhancing gastric secretory function,thereby ameliorating CAG development and cancer transformation.
文摘Context/Objective: Few studies have been carried out in a country with high endemicity for Helicobacter pylori (H. pylori) infection in Sub-Saharan Africa looking for the association of intestinal metaplasia (IM) with chronic gastritis. We hypothesize that IM is correlated with the intensity of H. pylori infection in a country with high endemicity, Ivory Coast. The objective of this study was to determine the prevalence of intestinal metaplasia in chronic H. pylori gastritis in Ivory Coast. Methods: This was a prospective, cross-sectional, multicenter study, carried out over a period of 5 months, in the reference hospital centers of Abidjan, specialized in Gastroenterology. All patients who had undergone Gastroscopy with biopsies according to the criteria of the Sydney System for the anatomopathological study, those with chronic gastritis and/or H. pylori intestinal metaplasia on histology and in whom all the parameters of the Sydney system classification had been well informed. The quantitative variables were expressed by their means accompanied by their standard deviations and the qualitative variables by their numbers and percentages. Chi-square and Fischer tests were used to look for associations between variables. The significance level was set at 5%. Results: 152 patients were retained. The mean age was 44.9 ± 12.9 years. The prevalence of intestinal metaplasia was 11.8%. In univariate analysis, no significant association was found between clinical and pathological sociodemographic factors (age, sex, ethnicity, educational level, profession) and intestinal metaplasia in chronic Helicobacter pylori gastric cases. In multivariate analysis we found that prolonged use of Proton Pump Inhibitors (PPIs) and a history of Gastroesophageal Reflux Disease (GERD) were significantly associated with the absence of IM. Conclusion: Chronic H. pylori gastritis is the main risk factor for intestinal metaplasia. Prolonged use of PPIs and a history of GERD were significantly identified as factors that would protect against intestinal metaplasia.
文摘BACKGROUND Autoimmune gastritis(AIG)is a progressive,chronic,immune-mediated inflammatory disease characterized by the destruction of gastric parietal cells leading to hypo/anacidity and loss of intrinsic factor.Gastrointestinal symptoms such as dyspepsia and early satiety are very common,being second in terms of frequency only to anemia,which is the most typical feature of AIG.AIM To address both well-established and more innovative information and knowledge about this challenging disorder.METHODS An extensive bibliographical search was performed in PubMed to identify guidelines and primary literature(retrospective and prospective studies,systematic reviews,case series)published in the last 10 years.RESULTS A total of 125 records were reviewed and 80 were defined as fulfilling the criteria.CONCLUSION AIG can cause a range of clinical manifestations,including dyspepsia.The pathophysiology of dyspepsia in AIG is complex and involves changes in acid secretion,gastric motility,hormone signaling,and gut microbiota,among other factors.Managing dyspeptic symptoms of AIG is challenging and there are no specific therapies targeting dyspepsia in AIG.While proton pump inhibitors are commonly used to treat dyspepsia and gastroesophageal reflux disease,they may not be appropriate for AIG.Prokinetic agents,antidepressant drugs,and non-pharmacological treatments may be of help,even if not adequately evidence-based supported.A multidisciplinary approach for the management of dyspepsia in AIG is recommended,and further research is needed to develop and validate more effective therapies for dyspepsia.
文摘BACKGROUND Chronic atrophic gastritis is a persistent disorder of the digestive system where the gastric mucosa epithelium and glands undergo atrophy,leading to a decrease in their number and thinning of the gastric mucosa.It is worth noting that the prevalence of chronic atrophic gastritis is higher in China compared to the global average,and it is also considered a precancerous condition for gastric cancer.AIM To evaluate the efficacy of Huangqi Jianzhong decoction in treating chronic atrophic gastritis.Chronic atrophic gastritis is a persistent illness characterized by the progressive disappearance of healthy gastric glands due to repeated injury.Huangqi Jianzhong decoctions are widely used in China to treat chronic atrophic gastritis.However,there is limited scientific evidence regarding their efficacy in treating this illness.METHODS The present meta-analysis adhered to the PRISMA guidelines and used the Cochrane Collaboration methodology.We performed a comprehensive search for clinical trials investigating the use of Huangqi Jianzhong decoction in treating chronic atrophic gastritis published until January 2023.The risk of bias and the quality of the included studies were evaluated using the Cochrane Handbook guidelines.Finally,a meta-analysis was conducted using the RevMan 5.4 softRESULTS This study included a total of 13 articles,comprising 1269 samples.The meta-analysis was conducted on these 13 articles,yielding the following results:I2=0%,P=0.60,[RR=1.24,95%CI:1.18 to 1.30,P<0.00001].The forest plot analysis of the Helicobacter pylori clearance rate revealed I2=0%,P=0.36,[RR=1.20,95%CI:1.05 to 1.38,P=0.009].The forest plot of PG-I level showed I2=99%,P<0.00001,[MD=4.99,95%CI:-1.59 to 11.58,P=0.14].The forest plot of stomach pain demonstrated I2=54%,P=0.04,[MD=-0.63,95%CI:-0.68 to-0.58,P<0.00001].The forest plot of reflux indicated I2=82%,P=0.0009,[MD=-0.48,95%CI:-0.63 to-0.33,P<0.00001].The forest plot of recurrence rate exhibited I2=0%,P=0.92,[RR=0.15,95%CI:0.04 to 0.66,P=0.01].The forest plot of adverse reactions showed no heterogeneity in outcome data,[RR=1.07,95%CI:0.53 to 2.17,P=0.86].CONCLUSION This study demonstrated that Huangqi Jianzhong decoction improved various factors in adults with chronic atrophic gastritis.These factors included the total effective rate,Helicobacter pylori clearance rate,symptoms such as stomachache and acid reflux alleviation,and recurrence rates.

文摘Chronic gastritis (CG) is an inflammatory condition of the gastric mucosa, induced by various causes. A commonly-seen disease in clinical practice, it is found in about 80%-90% of patients undergoing gastroscopic examination. The prevalence rate in the general population remains unclear. It is generally considered that its incidence rate accords with Helicobacter. pylori infection rate and the prevalence of CG is 30%-80% in China. Possible etiological factors include H. pylori infection, smoking, drinking alcohol, food allergies, duodenal juice reflux, drug-induced injuries, heredity, immunity, and radiation.^[1-8].
文摘A lot of attention has been given to the effects of cell adhesion molecules(cAM).In thispaper,the immunohistochemistry method was used to compare and investigate in situ expression of intercellular adhesion molecule-1(ICAM-1,CD54)in gastric carcinoma and chronic gastritis.The result showed that,by comparison with normal mucosa of stomach,there were a great number Of ICAM-1+cells infiltrating.the numbers of the cells were paralleled to the degree of the pathologicchanges.Meanwhile,there were muck fewer ICAM-1+cells in gastric carcinoma tissue.More thanthat,the fewer ICAM-1+cells were seen in the lower differentiated tumors than those in higher differentiated ones. This suggests that ICAM-1 is related to the local immunological tolerence of gastriccarcinoma.
