Meta-Analysis Review
BACKGROUND
Helicobacter pylori (H pylori) infection has been implicated in a number of malignancies and non-malignant conditions including peptic ulcers, non-ulcer dyspepsia, recurrent peptic ulcer bleeding, unexplained iron deficiency anaemia, idiopathic thrombocytopaenia purpura, and colorectal adenomas. The confirmatory diagnosis of H pylori is by endoscopic biopsy, followed by histopathological examination using haemotoxylin and eosin (H & E) stain or special stains such as Giemsa stain and Warthin-Starry stain. Special stains are more accurate than H & E stain. There is significant uncertainty about the diagnostic accuracy of non-invasive tests for diagnosis of H pylori.
OBJECTIVES
To compare the diagnostic accuracy of urea breath test, serology, and stool antigen test, used alone or in combination, for diagnosis of H pylori infection in symptomatic and asymptomatic people, so that eradication therapy for H pylori can be started.
SEARCH METHODS
We searched MEDLINE, Embase, the Science Citation Index and the National Institute for Health Research Health Technology Assessment Database on 4 March 2016. We screened references in the included studies to identify additional studies. We also conducted citation searches of relevant studies, most recently on 4 December 2016. We did not restrict studies by language or publication status, or whether data were collected prospectively or retrospectively.
SELECTION CRITERIA
We included diagnostic accuracy studies that evaluated at least one of the index tests (urea breath test using isotopes such as C or C, serology and stool antigen test) against the reference standard (histopathological examination using H & E stain, special stains or immunohistochemical stain) in people suspected of having H pylori infection.
DATA COLLECTION AND ANALYSIS
Two review authors independently screened the references to identify relevant studies and independently extracted data. We assessed the methodological quality of studies using the QUADAS-2 tool. We performed meta-analysis by using the hierarchical summary receiver operating characteristic (HSROC) model to estimate and compare SROC curves. Where appropriate, we used bivariate or univariate logistic regression models to estimate summary sensitivities and specificities.
MAIN RESULTS
We included 101 studies involving 11,003 participants, of which 5839 participants (53.1%) had H pylori infection. The prevalence of H pylori infection in the studies ranged from 15.2% to 94.7%, with a median prevalence of 53.7% (interquartile range 42.0% to 66.5%). Most of the studies (57%) included participants with dyspepsia and 53 studies excluded participants who recently had proton pump inhibitors or antibiotics.There was at least an unclear risk of bias or unclear applicability concern for each study.Of the 101 studies, 15 compared the accuracy of two index tests and two studies compared the accuracy of three index tests. Thirty-four studies (4242 participants) evaluated serology; 29 studies (2988 participants) evaluated stool antigen test; 34 studies (3139 participants) evaluated urea breath test-C; 21 studies (1810 participants) evaluated urea breath test-C; and two studies (127 participants) evaluated urea breath test but did not report the isotope used. The thresholds used to define test positivity and the staining techniques used for histopathological examination (reference standard) varied between studies. Due to sparse data for each threshold reported, it was not possible to identify the best threshold for each test.Using data from 99 studies in an indirect test comparison, there was statistical evidence of a difference in diagnostic accuracy between urea breath test-C, urea breath test-C, serology and stool antigen test (P = 0.024). The diagnostic odds ratios for urea breath test-C, urea breath test-C, serology, and stool antigen test were 153 (95% confidence interval (CI) 73.7 to 316), 105 (95% CI 74.0 to 150), 47.4 (95% CI 25.5 to 88.1) and 45.1 (95% CI 24.2 to 84.1). The sensitivity (95% CI) estimated at a fixed specificity of 0.90 (median from studies across the four tests), was 0.94 (95% CI 0.89 to 0.97) for urea breath test-C, 0.92 (95% CI 0.89 to 0.94) for urea breath test-C, 0.84 (95% CI 0.74 to 0.91) for serology, and 0.83 (95% CI 0.73 to 0.90) for stool antigen test. This implies that on average, given a specificity of 0.90 and prevalence of 53.7% (median specificity and prevalence in the studies), out of 1000 people tested for H pylori infection, there will be 46 false positives (people without H pylori infection who will be diagnosed as having H pylori infection). In this hypothetical cohort, urea breath test-C, urea breath test-C, serology, and stool antigen test will give 30 (95% CI 15 to 58), 42 (95% CI 30 to 58), 86 (95% CI 50 to 140), and 89 (95% CI 52 to 146) false negatives respectively (people with H pylori infection for whom the diagnosis of H pylori will be missed).Direct comparisons were based on few head-to-head studies. The ratios of diagnostic odds ratios (DORs) were 0.68 (95% CI 0.12 to 3.70; P = 0.56) for urea breath test-C versus serology (seven studies), and 0.88 (95% CI 0.14 to 5.56; P = 0.84) for urea breath test-C versus stool antigen test (seven studies). The 95% CIs of these estimates overlap with those of the ratios of DORs from the indirect comparison. Data were limited or unavailable for meta-analysis of other direct comparisons.
AUTHORS' CONCLUSIONS
In people without a history of gastrectomy and those who have not recently had antibiotics or proton ,pump inhibitors, urea breath tests had high diagnostic accuracy while serology and stool antigen tests were less accurate for diagnosis of Helicobacter pylori infection.This is based on an indirect test comparison (with potential for bias due to confounding), as evidence from direct comparisons was limited or unavailable. The thresholds used for these tests were highly variable and we were unable to identify specific thresholds that might be useful in clinical practice.We need further comparative studies of high methodological quality to obtain more reliable evidence of relative accuracy between the tests. Such studies should be conducted prospectively in a representative spectrum of participants and clearly reported to ensure low risk of bias. Most importantly, studies should prespecify and clearly report thresholds used, and should avoid inappropriate exclusions.

Meta-Analysis Review
OBJECTIVE
The role of gastritis in dyspepsia remains controversial. We aimed to examine the efficacy of rebamipide, a gastric mucosal protective agent, in both organic and functional dyspepsia.
DESIGN
A systematic review and meta-analysis was performed. The following databases were searched using the keywords ("rebamipide" OR "gastroprotective agent*" OR "mucosta") AND ("dyspepsia" OR "indigestion" OR "gastrointestinal symptoms"): PubMed, Wed of Science, Embase, CINAHL, Cochrane Clinical Trials Register. The primary outcome was dyspepsia or upper GI symptom score improvement. Pooled analysis of the main outcome data were presented as risk ratio (RR) for dichotomous data and standardized mean difference (SMD) for continuous data.
RESULTS
From an initial 248 records, 17 randomised controlled trial (RCT) publications involving 2170 subjects (1224 rebamipide, 946 placebo/control) were included in the final analysis. Twelve RCTs were conducted in subjects with organic dyspepsia (peptic ulcer disease, reflux esophagitis or NSAID-induced gastropathy) and five RCTs were conducted in patients with functional dyspepsia (FD). Overall, dyspepsia symptom improvement was significantly better with rebamipide compared to placebo/control drug (RR 0.77, 95% CI = 0.64-0.93; SMD -0.46, 95% CI = -0.83 to -0.09). Significant symptom improvement was observed both in pooled RR and SMD in subjects with organic dyspepsia (RR 0.72, 95% CI = 0.61-0.86; SMD -0.23, 95% CI = -0.4 to -0.07), while symptom improvement in FD was observed in pooled SMD but not RR (SMD -0.62, 95% CI = -1.16 to -0.08; RR 1.01, 95% CI = 0.71-1.45).
CONCLUSION
Rebamipide is effective in organic dyspepsia and may improve symptoms in functional dyspepsia.

Meta-Analysis
BACKGROUND
Since the previous network meta-analysis assessing the efficacy of prokinetics for functional dyspepsia (FD), there have been a number of new studies and cinitapride is a new prokinetic agent for FD. This updated meta-analysis aimed to explore the efficacy and safety of prokinetics for FD.
METHODS
An updated study search in Pubmed, EMBASE, Cochrane Library and Web of Science was conducted in literatures published from July 2015 to March 2023. Randomized controlled trials investigating the use of prokinetics in adult FD patients were included. The primary outcome was the total efficacy rate and the secondary outcome was adverse events. A Bayesian network meta-analysis was performed using R software.
RESULTS
A total of 28 studies were included. Network meta-analysis showed that metoclopramide had a higher total efficacy rate than mosapride (OR: 3.53, 95%CI: 1.70-7.47), domperidone (OR: 2.29, 95%CI: 1.16-4.63), itopride(OR: 2.77, 95%CI: 1.41-5.59), acotiamide(OR: 2.63, OR: 1.33-5.36), and placebo(OR: 5.68, 95%CI: 2.98-11.10), however similar to cinitapride (OR: 1.62, 95%CI: 0.75-3.53). Cinitapride had a higher total efficacy rate than mosapride (OR: 2.18, 95%CI: 1.16-4.14) and placebo (OR: 3.52, 95%CI: 2.01-6.24). Cinitapride had lower risk of total adverse events than domperidone. There was no difference in the risk of drug-related adverse events between the prokinetics.
CONCLUSIONS
Metoclopramide and cinitapride may have a better efficacy than other prokinetics in the treatment of FD, and cinitapride may have a lower risk of total adverse events. Further studies using uniform definitions or validated tools to measure the total efficacy rate are needed.

Meta-Analysis Review
OBJECTIVES
The use of acupuncture treatment (AT) for functional dyspepsia is increasing, particularly in Asia. However, the efficacy of AT and its side effects have not been assessed. We performed a systematic review and meta-analysis of studies related to the effectiveness of AT for functional dyspepsia.
DESIGN
This study is a systemic review and meta-analysis. Seven electronic databases, including those in the English and Chinese languages, were systematically searched for randomized controlled trials of AT for functional dyspepsia through November 2012. There were no language restrictions.
SETTING
Randomized controlled trials (RCT) AT compared with placebo control or a comparative intervention were considered. The methodological qualities of the studies were evaluated using the risk of bias (ROB). Subgroups were analyzed according to the kinds of controls.
MAIN OUTCOME MEASURES
The primary outcomes were symptom scores. These included visual analogue scale (VAS) and Nepean Dyspepsia Index (NDI). Secondary outcomes were the total effective rate and adverse effects.
RESULTS
Twenty studies, including 1423 individual cases, were systematically reviewed. The risk of bias was high. Compared to sham AT, AT was associated with a significant positive effect in patients with functional dyspepsia (2.66, 95% CI 1.85-3.82). AT also improved symptoms for functional dyspepsia (1.18, 95% CI 1.01-2.60) compared to GI tract regulators on total effective rate. In addition, two articles produced a scale in favor of AT compared to medication (0.54, 95% CI 0.18-0.90). Two RCTs reported minimal AT-related adverse events.
CONCLUSIONS
The evidence suggests that AT is effective for functional dyspepsia. However, well-planned, long-term studies are necessary to evaluate the efficacy of AT for functional dyspepsia.

Review
Functional dyspepsia (FD) is a common chronic gastrointestinal disorder with a complex, undefined mechanism. Clustering of patients with FD in families highlights the role of genetic factors in the pathogenesis of FD. We performed a systematic review and meta-analysis to clarify the associations between specific gene polymorphisms and FD susceptibility. PubMed, EMBASE, the Cochrane Library, and HuGE database were searched. An additive model was adopted to determine whether previous studied genes are associated with FD susceptibility. Carriers of minor allele in GNB3 825C>T (OR = 1.15, 95% CI 0.99-1.34, = 0.07), SCL6A4 5HTTLPR (OR = 0.92, 95% CI 0.75-1.12, = 0.40), and CCK-1R 779T>C (OR = 0.86, 95% CI 0.72-1.03, = 0.09) genes failed to demonstrate susceptibility to FD. In a subgroup analysis, only minor allele (T) in GNB3 825C>T was associated with an increased susceptibility to the epigastric pain syndrome subtype (OR = 1.34, 95% CI 1.10-1.63, = 0.003). Our meta-analysis based on available studies using an additive model failed to show that GNB3, SCL6A4, and CCK-1R polymorphisms are associated with FD susceptibility.

Meta-Analysis Review
BACKGROUND & AIMS
Dyspepsia and irritable bowel syndrome (IBS) are common conditions that can coexist in patients. We performed a systematic review and meta-analysis to estimate prevalence of IBS in dyspepsia.
METHODS
Relevant articles published through August 2008 were identified from MEDLINE and EMBASE literature searches (23,457 citations). Eligible studies included adults recruited from the community, the workplace, blood donation or screening clinics, and family physician offices or internal medicine clinics. Selected studies reported prevalence of dyspepsia and IBS within the same population. The prevalence of IBS in subjects with and without dyspepsia was pooled for all studies and compared. Odds ratios (OR) and confidence intervals (CI) were calculated. The degree of overlap between dyspepsia and IBS was determined.
RESULTS
Of 239 papers evaluated, 150 reported prevalence of dyspepsia and 19 (involving 18,173 subjects) reported the proportion of subjects with IBS within the same population. The prevalence of dyspepsia was 27% (95% CI, 23%-31%). The prevalence of IBS in subjects with dyspepsia was 37% (95% CI, 30%-45%) compared with 7% (95% CI, 5%-10%) in those without. The pooled OR for IBS in subjects with dyspepsia was 8 (95% CI, 5.74-11.16). The degree of overlap between the 2 conditions varied from 15% to 42%, depending on diagnostic criteria used for each.
CONCLUSIONS
Individuals with dyspepsia have an 8-fold increase in prevalence of IBS compared with the population. The strength of the association suggests common pathogenic mechanisms. Dyspeptic patients should be assessed routinely for IBS.

Review
This systematic review and meta-analysis determine how frequently and how seriously gastrointestinal manifestations affect people with type 2 diabetes mellitus on tirzepatide. Tirzepatide is a recently developed drug that attempts to enhance type 2 diabetics' ability to regulate their blood sugar levels and promote weight reduction. Despite its potential benefits, clinical trials have revealed that the medication may lead to gastrointestinal side effects, including nausea, vomiting, decreased appetite, dyspepsia, constipation, and diarrhea. These side effects may negatively affect the drug's efficacy and patient tolerance. A comprehensive search of electronic databases such as PubMed, Web of Science, and Cochrane Library, was conducted to find pertinent studies reporting on the frequency and severity of gastrointestinal symptoms in type 2 diabetes patients receiving tirzepatide. This systematic review follows the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Study selection, data extraction, and quality assessment were performed. Six randomized controlled trials with a total of 4,586 patients were included. Most patients received tirzepatide to regulate their blood sugar levels and promote weight reduction, and the comparators were placebo, glucagon-like peptide one receptor agonists drugs, and insulin degludec. The dose of tirzepatide was 5mg, 10mg, and 15mg weekly. The incidence rate of nausea in patients who receive tirzepatide was 20.43%, while the incidence rate in the comparators was 10.47%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 2.90; 95% CI, 1.89 to 4.44; P ≤ 0.00001). The incidence rate of vomiting in patients who receive tirzepatide was 9.05%, while the rate in the comparators was 4.86%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 2.69; 95% CI, 1.67 to 4.36; P ≤ 0.0001). The incidence rate of constipation in patients who receive tirzepatide was 2.54%, while the rate in the comparators was 0.856%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 3.08; 95% CI, 1.83 to 5.20; P ≤ 0.0001). The incidence rate of decreased appetite in patients who receive tirzepatide was 9.64%, while the rate in the comparators was 2.88%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 5.04; 95% CI, 3.01 to 8.45; P ≤ 0.00001). The incidence rate of diarrhea in patients who receive tirzepatide was 16.24%, while the rate in the comparators was 8.63%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 2.07; 95% CI, 1.60 to 2.68; P ≤ 0.00001). The incidence rate of dyspepsia in patients who receive tirzepatide was 7.13%, while the rate in the comparators was 3.31%, and it was significantly higher in the tirzepatide arm than in the comparators (RR, 2.52; 95% CI, 1.58 to 4.01; P ≤ 0.0001). Tirzepatide usage is linked to a significant prevalence of gastrointestinal symptoms, including nausea, constipation, decreased appetite, dyspepsia, diarrhea, and vomiting, in people with type 2 diabetes. These findings may influence clinical decision-making and patient counseling on the use of tirzepatide and have significant implications for the medication's tolerance and efficacy. To find ways to reduce these negative effects and improve therapy for type 2 diabetes patients, more research is required.

Meta-Analysis
Functional dyspepsia (FD) is a gastrointestinal disorder of unknown etiology. Although micro-inflammation appears to be important in the pathogenesis, studies evaluating immune activation in FD have been inconsistent. A systematic review of literature and meta-analysis was performed to compare immunologic cell counts and cytokine levels in the mucosa and peripheral blood of individuals with FD and healthy controls. PubMed, Embase, and the Cochrane library were searched. Data on immunologic cell counts and cytokines levels among individuals with FD and control groups were extracted and compared by calculating standard mean differences (SMD). Thirty-seven studies met the inclusion criteria. Mast cell (SMD = 0.94, 95%CI 0.26-1.62, P = .007) and eosinophil counts (SMD = 0.36, 95%CI 0.06-0.68, P = .03) in the stomach were increased, among individuals with FD compared to controls. Similarly, mast cell (SMD = 0.66, 95%CI 0.20-1.13, P = 0.005) and eosinophil (SMD = 0.95, 95%CI 0.66-1.24; P < .001) counts in the duodenum were also increased in those with FD compared to controls. In a subgroup analysis, elevated eosinophil counts in the duodenum were observed in both post-prandial distress syndrome (SMD = 0.97, 95%CI 0.46-1.47, P = .0002) and epigastric pain syndrome subtypes (SMD = 1.16, 95%CI 0.48-1.83, P = .0008). No differences in mucosal intraepithelial lymphocyte, enterochromaffin cell, and neutrophil counts, as well as, peripheral interlukin-6 (IL-6) and IL-10 levels were observed among individuals with FD and controls. Micro-inflammation in the form of local immune cell infiltration, particularly eosinophils and mast cells, characterizes the pathogenesis of FD.

Meta-Analysis
Cholecystolithiasis and functional gastrointestinal disorders are both highly prevalent in the industrialized world and may exist concomitantly. The presence of both conditions impedes identification of the source of symptoms, leading to a risk of ineffective cholecystectomies with lack of symptom resolution. We carried out a systematic review and meta-analysis to determine the prevalence of dyspepsia in patients with uncomplicated cholecystolithiasis. The electronic databases Medline, Embase, and Web of Science were searched for articles reporting the prevalence of dyspepsia in adults (≥18 years) with uncomplicated cholecystolithiasis. Pooled prevalence and 95% confidence interval were calculated. I statistics were used to determine heterogeneity and the Methodological Evaluation of Observational Research criteria were applied for quality assessment. The study was reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Of the 1696 studies evaluated, 13 reported the prevalence of dyspepsia in a total of 1227 cholecystolithiasis patients seeking medical care. The pooled prevalence of dyspepsia in patients with cholecystolithiasis was 65.7% (95% confidence interval: 51-79%). However, heterogeneity was large across studies. Overall, three studies used validated diagnostic criteria. Variation in diagnostic measures significantly influenced the prevalence of dyspepsia. In conclusion, symptoms similar to those of functional gastrointestinal disorders are common in patients with cholecystolithiasis, obscuring the source of abdominal complaints. Tools to select patients who will benefit from cholecystectomy are paramount to prevent ineffective surgery.

Review
Objective Functional dyspepsia (FD) is defined as persistent or recurrent pain or discomfort centered in the upper abdomen without organic disease. Psychosocial factors have been proposed as an important element in the pathophysiology of FD. Therefore, psychotropic agents having antianxiety or antidepressive action are expected to alleviate FD. We previously reported on the treatment of FD using such agents in a systematic review, wherein the effectiveness of the agents on FD was suggested, although there were several limitations. We searched for articles on this subject after our systematic review and re-reviewed them systematically. Methods Articles were searched for in MEDLINE from 2003 to 2014 using terms related to antianxiety or antidepressive agents. Clinical studies in which the effectiveness of such agents was clearly stated were selected from the retrieved articles. The newly selected and previously selected studies were combined, and statistical analyses were carried out. Results Nine studies were selected. Five of the studies indicated a significant symptomatic improvement using psychotropic drugs. A statistical analysis suggested a significant treatment effect of psychotropic agents having antianxiety or antidepressive action [pooled relative risk (PRR), 0.72; 95% confidence interval (95% CI), 0.52-0.99; p=0.0406] but did not show a significant benefit of treatment with agents having an antidepressive action alone (PRR, 0.63; 95% CI, 0.38-1.03; p=0.0665). Conclusion Our systematic review suggested that psychotropic drugs having antianxiety and antidepressive actions as a whole might be effective in alleviating FD symptoms, whereas those having only antidepressive action were not effective.
