Meta-Analysis Review
Helicobacter pylori (H. pylori) infection is a major cause of duodenal ulcers, gastric ulcers, and gastric cancer. However, the optimal duration for H. pylori eradication therapy remains controversial. Most studies have mainly focused on triple therapy, and there is insufficient research on bismuth-containing quadruple therapy. The aim of this study was to compare the clinical effect of the 10-day bismuth-containing quadruple treatment regimen with the 14-day regime in eradicating H. pylori. We searched PubMed, Embase, Web of Science, and the Cochrane Library for randomized controlled trials published in English until May 2022 according to the eligibility criteria. Summary risk ratios (RRs) and 95% confidence intervals (CIs) for eradication rates, adverse effects, and compliance were calculated for included studies. Four studies, involving 1173 patients, were eligible for inclusion. The eradication rate was similar in the 10-day treatment group and the 14-day treatment group in the intention-to-treat analysis (RR 0.97, 95% CI 0.93 to 1.01). Meanwhile, the incidence of adverse effects was lower in patients who received 10 days of treatment than in those who received 14 days of treatment and patients' compliance was almost the same between two groups. Compared to the 14-day bismuth-containing quadruple regimens, 10-day regimens had similar efficacy and lower incidence of adverse effects. Therefore, the 10-day regimen is safe and well-tolerated and should be recommended for H. pylori infection.

Meta-Analysis Review
BACKGROUND
Pharmacovigilance risk signals have proposed a relationship between the use of acid-suppressive medications and the development of certain autoimmune and immune-mediated inflammatory diseases.
OBJECTIVE
A systematic review and a meta-analysis was performed.
METHODS
We reviewed MEDLINE (Ovid) and Scopus for comparative observational studies between these diseases and previous exposure to proton-pump inhibitors (PPI), H2-receptor antagonists (H2RA), and antacids. The protocol was registered on the PROSPERO database (CRD42020192715).
RESULTS
From 3,191 citations, 25 articles were eligible and covered 16 diseases. Microscopic colitis (MC) was studied the most (7 studies). In a random-effects meta-analysis, there was low certainty evidence (GRADE approach) of a non-significant relationship between exposure to any PPIs and MC (meta-OR 3.28, 95% CI 0.98-11.0, I2 98.2%, six studies, 4,436 PPI-exposed MC patients). Moderate certainty evidence pointed towards large odds of collagenous colitis after exposure to lansoprazole (meta-OR 14.5, 95% CI 9.37-22.3, I2 10.2%, three studies, 1,725 lansoprazole-exposed patients). After PPI exposure, the risk of rheumatoid arthritis was slightly increased based on low certainty evidence from two cohort studies totaling 475 diagnoses (meta-RR 1.62, 95% CI 1.12-2.34, I2 34.5%).
CONCLUSIONS
In patients with MC, it would be reasonable to carefully review the indication of PPI, especially in CC patients using lansoprazole.

Review
BACKGROUND
To systematically evaluate the quality of the guidelines for the diagnosis and treatment of Helicobacter pylori infection and to analyze the differences and reasons for the key recommendations in the guidelines.
METHODS
Databases and websites were systematically searched to obtain guidelines for the diagnosis and treatment of Helicobacter pylori infection. Four independent reviewers used the Guideline Evaluation Tool (AGREE II) to evaluate the included guidelines. The intraclass correlation coefficient (ICC) and Fleiss' kappa coefficient were used to measure the consistency of evaluation guidelines between guide reviewers. Differences between guidelines and the reasons for the differences were analyzed by comparing the recommendations of different guidelines and the evidence supporting the recommendations.
RESULTS
A total of 17 guidelines for Helicobacter pylori infection were included in this study. The AGREE II scores of these guidelines were low overall, with 4 of them had a score of over 60%, which indicates that the guidelines are recommended, and 13 of them having a score ranging from 30 to 60%, which indicates that the guidelines are recommended but need to be revised, while no guideline had a score of 30% or less, which indicates that they were not recommended. The analysis of these guidelines found that there were some differences in the main recommendations. Not all guidelines recommend sequential therapy as the recommended therapy. Whether bismuth quadruple therapy should be used as the recommended first-line therapy is unclear. The antibiotic resistance rate is different in different regions. Combined with the local antibiotic sensitivity test, the eradication rate of Helicobacter pylori can be improved.
CONCLUSION
There are significant differences in the quality of Helicobacter pylori infection guidelines and the key recommendations. Improving the deficiencies of existing guidelines is an effective way to develop high-quality guidelines and make reasonable recommendations for the treatment of Helicobacter pylori infection in the future.

Meta-Analysis
The influence of antacids use on immune checkpoint inhibitor (ICI) efficacy remains unclear. A systematic review and meta-analysis was performed to evaluate the effect of proton pump inhibitors (PPIs) and histamine-2-receptor antagonists (H2RAs) on ICI efficacy in advanced solid cancer patients. A systematic literature search in PubMed, EMBASE, and Web of Science was performed to retrieve studies investigating the effect of antacid use on ICI efficacy. Overall survival (OS), progression-free survival (PFS), objective response rate (ORR), and immune-related adverse events were measured using hazard ratios (HRs) or odds ratios (ORs). Thirty studies enrolling 16,147 advanced cancer patients receiving ICI treatment were included. The pooled analysis indicated that PPI use was associated with shorter OS (HR=1.40, 95% CI, 1.25-1.57) and PFS (HR=1.34, 95% CI, 1.19-1.52) in advanced cancer patients treated with ICIs. PPI use did not show effect on ORR or immune-related adverse event of advanced cancer patients receiving ICI treatment. OS, PFS, and ORR did not differ between H2RA users and non-H2RA users. In subgroup analyses, PPI use was associated with shorter OS and PFS in NSCLC and urothelial carcinoma patients and in patients treated with anti-programmed cell death 1 or anti-programmed cell death ligand 1 monotherapy. In addition, ICI efficacy was different in the antacid exposure time frame subgroups. In conclusion, PPI use has a negative effect on OS and PFS among advanced cancer patients receiving ICI treatment. PPIs should be cautiously administered among advanced cancer patients treated with ICI. The safety of H2RAs and the influence of H2RAs on ICI efficacy need further investigation.

Meta-Analysis Review
BACKGROUND & AIMS
Antibiotic resistance of Helicobacter pylori (H. pylori) is increasing worldwide, and bismuth quadruple therapy has been recommended as a first-line regimen in many areas. This study aimed to investigate whether bismuth would improve the eradication rate (ER) of clarithromycin-/metronidazole-/levofloxacin-resistant H. pylori strains and how much additional efficacy bismuth could achieve.
METHODS
PubMed, EMBASE, Web of Science, and Cochrane Central databases for randomized controlled trials were systematically searched by two independent reviewers until 15 January 2022. Pooled ERs of clarithromycin-/metronidazole-/levofloxacin-resistant H. pylori strains were compared between bismuth-containing and non-bismuth therapies. Pooled risk ratios (RRs) with 95% confidence intervals (CIs) were calculated using a random-effects model.
RESULTS
Eight studies enrolling 340 individuals were included. The RRs of pooled ERs compared between bismuth-containing and non-bismuth therapies were 1.83 for clarithromycin-resistant strains (95% CI 1.16-2.89, pooled ER: 76.9% vs. 36.6%, p = .009, I = 0%), 1.39 for metronidazole-resistant strains (95% CI 1.09-1.78, pooled ER: 86.8% vs. 60.9%, p = .008, I = 37%), 2.75 for dual clarithromycin/metronidazole-resistant strains (95% CI 1.01-7.52, pooled ER: 76.9% vs. 18.2%, p = .05, I = 0%), and 1.04 for levofloxacin-resistant strains (95% CI 0.56-1.93, pooled ER: 63.4% vs. 54.3%, p = .90; I = 60%). Bismuth significantly increased the ERs of clarithromycin-, metronidazole-, and dual-resistant strains by 40%, 26%, and 59%, respectively. Subgroup analysis of treatment duration showed that the significantly higher eradication rate for antibiotic-resistant strains in bismuth-containing therapy than non-bismuth therapy was only observed in 14-day treatment regimens and not in 7-day regimens (p = .02 and .17, respectively).
CONCLUSIONS
Bismuth was most effective in improving the ERs of dual-resistant H. pylori strains, followed by clarithromycin- and metronidazole-resistant strains. Prolonged treatment duration might effectively improve the efficacy of bismuth in overcoming antibiotic resistance.

Meta-Analysis
BACKGROUND
This study aimed to evaluate the efficacy and safety of high-dose dual therapy for Helicobacter pylori (H. pylori) eradication compared to bismuth-containing quadruple therapy.
METHODS
The electronic database of PubMed, Embase, and Cochrane Library were searched from inception to March 18, 2021. Randomized, controlled trials that evaluated high-dose dual therapy versus bismuth-containing quadruple therapy for H. pylori infection were included.
RESULTS
We included 6 studies containing 1677 patients with H. pylori infection. This meta-analysis demonstrated that high-dose dual therapy achieved similar eradication rate compared with bismuth-containing quadruple therapy (intention-to-treat: 84.6% vs 83.7%, relative risk (RR) = 1.01, 95% CI: 0.97-1.06, P = .49; per-protocol = 88.4% vs 89.0%, RR = 1.00, 95% CI: 0.97-1.04, P = .99). However, highdose dual therapy showed fewer side effects (13.1% vs 32.0%, RR = 0.51, 95% CI: 0.34-0.78, P = .002) and better compliance (96.1% vs 93.3%, RR = 1.03, 95% CI: 1.00-1.05, P = .03) compared to bismuth-containing quadruple therapy.
CONCLUSION
This meta-analysis demonstrated that high-dose dual therapy is equally effective with bismuth-containing quadruple therapy in eradicating H. pylori, with fewer side effects and better compliance.

BACKGROUND
Curing H. pylori infection remains challenging, and the use of most effective first-line therapy represents a therapeutic cornerstone. To monitor the efficacy of first-line therapies in Italy, we designed a systematic review with pooled- data analysis of data published in the last 15 years.
METHODS
The search was focused on standard regimens and adult patients. Studies that included modified therapy regimens, pediatric patients, case series with less than 5 patients, and those in language other than English were excluded.
RESULTS
A total of 40 studies, with 74 therapeutic arms and 13,539 patients were evaluated. Among the 14-day triple therapies, the combination with proton pump inhibitor (PPI), clarithromycin and amoxicillin achieved the highest (77.9%) success rate, whilst the lowest success rate (62.7%) was observed following the 14-day PPI, clarithromycin and tinidazole regimen. The overall efficacy of triple therapies significantly decreased from 75.7% to 72.1% in the last decade. Sequential (88.3% on 3431 patients), concomitant (88.8% on 376 patients), and the bismuth-based quadruple therapy with three-in-one capsule, containing bismuth subcitrate potassium (140 mg), metronidazole (125 mg), tetracycline (125 mg) (90.4% on 999 patients) achieved similarly high eradication rates, but data on concomitant are still limited. The bismuth-based was associated with the higher (38.7%) incidence of side-effects.
CONCLUSIONS
Data found that all triple therapies, irrespective of drug combination and therapy duration, should be abandoned in Italy due to their unacceptable low success rates. Monitoring the efficacy of standard first-line therapies in other countries could be clinically useful for both patients and clinicians.

Meta-Analysis
Idiopathic pulmonary fibrosis (IPF) is a fibrosing interstitial pneumonia with impaired survival. Previous guidelines recommend antacid medication to improve respiratory outcomes in patients with IPF. This systematic review was undertaken during the development of an American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Asociación Latinoamericana del Tórax guideline. The clinical question was, "Should patients with IPF who have documented abnormal gastroesophageal reflux (GER) with or without symptoms of GER disease ) be treated with antacid medication or ) undergo antireflux surgery to improve respiratory outcomes?" Medline, Embase, the Cochrane Central Register of Controlled Trials, and the gray literature were searched through June 30, 2020. Studies that enrolled patients with IPF and ) compared antacid medication to placebo or no medication or ) compared antireflux surgery to no surgery were selected. Meta-analyses were performed when possible. Outcomes included disease progression, mortality, exacerbations, hospitalizations, lung function, respiratory symptoms, GER severity, and adverse effects/complications. For antacid medication, when two studies were aggregated, there was no statistically significant effect on disease progression, defined as a 10% or more decline in FVC, more than 50-m decline in 6-minute walking distance, or death (risk ratio [RR], 0.88; 95% confidence interval [CI], 0.76-1.03). A separate study that could not be included in the meta-analysis found no statistically significant effect on disease progression when defined as a 5% or more decline in FVC or death (RR, 1.10; 95% CI, 1.00-1.21) and an increase in disease progression when defined as a 10% or more decline in FVC or death (RR, 1.28; 95% CI, 1.08-1.51). For antireflux surgery, there was also no statistically significant effect on disease progression (RR, 0.29; 95% CI, 0.06-1.26). Neither antacid medications nor antireflux surgery was associated with improvements in the other outcomes. There is insufficient evidence to conclude that antacid medication or antireflux surgery improves respiratory outcomes in patients with IPF, most of whom had not had abnormal GER confirmed. Well-designed and adequately powered prospective studies with objective evaluation for GER are critical to elucidate the role of antacid medication and antireflux surgery for respiratory outcomes in patients with IPF.

Meta-Analysis
OBJECTIVE
To assess the benefit and harm of Chinese medicine Xianling Gubao (XLGB) capsule compared to conventional medication or placebo to inform clinical practice.
METHODS
We included randomized controlled trials (RCTs) with Jadad score ≥3 of XLGB capsule compared to pharmaceutical medication, placebo, or no treatment for primary osteoporosis. We conducted searches in EMBASE, Cochrane CENTRAL, MEDLINE, China National Knowledge Infrastructure, VIP, Wanfang, and Chinese Biomedical Literature Database (Sino-Med) from their inception till November 13, 2021. Study selection and data extraction were done by two authors independently. The methodological quality of the RCTs was assessed using Cochrane's risk of bias tool. The effect size was presented as risk ratio (RR) or mean difference (MD) with their 95% confidence interval (CI).
RESULTS
Our searches identified 2292 records and after exclusions, eight trials involving 846 participants were included. There was no statistically significant difference between conventional medications with or without XLGB on new fracture (RR: 0.50, 95% CI: [0.13, 1.87]). Quality of life by SF-36 questionnaire of XLGB plus calcium carbonate, vitamin D, and calcitriol was improved than that of without XLGB (MD: 6.72 scores, 95% CI: [2.82, 10.62]). XLGB increased bone mineral density similarly as calcium carbonate plus vitamin D (MD: 0.21, 95% CI: [-0.16, 0.58]) or as alendronate sodium, calcium carbonate plus vitamin D (MD: 0.00, 95% CI: [-0.10, 0.10]), but it had no additional effect as an add-on treatment to conventional medications (MD: 0.13, 95% CI: [-0.12, 0.37]). XLGB relieved pain visual analog scale more effectively when combined with medications (MD: -1.55 score, 95% CI: [-2.47, -0.63]). XLGB as monotherapy did not increase adverse events (RR: 0.63, 95% CI: [0.28, 1.41]), or as an add-on treatment (RR: 0.25, 95% CI: [0.03, 2.16]).
CONCLUSION
This systematic review shows that XLGB capsule appears to be safe and has a beneficial effect on the quality of life and pain relief when used alone or in combination with conventional medications in osteoporosis patients. Further large, rigorous trials are warranted to test its long-term benefit.

Review
(1) Background: In recent years, immunotherapy has revolutionized the treatment landscape of non-small cell lung cancer (NSCLC), representing a therapeutic breakthrough in this field. Antacid agents such as proton pump inhibitors (PPIs) and histamine-2-receptor antagonists (H2RAs) are commonly prescribed for extended periods in NSCLC patients, and these drugs have the potential to modify the efficacy of immune checkpoint inhibitors (ICIs). (2) Materials and Methods: Herein, we conducted a systematic review and meta-analysis to investigate the impact of PPIs and H2RAs on progression-free survival (PFS) and overall survival (OS) among patients receiving immunotherapy for metastatic NSCLC. Effect measures for OS were Hazard Ratios (HRs) and 95% Confidence Intervals (CIs), which were extracted from available studies. Forest plots were used to assess HRs to describe the relationship between treatment and OS in the specified cohorts of patients. (3) Results: Six studies were included in the analysis, involving 2267 patients. The pooled HRs for OS and PFS were 1.4 (95% CI, 1.25-1.58) and 1.29 (95% CI, 1.17-1.43), respectively, suggesting that PPIs and H2RAs administration was negatively associated with PFS and OS. (4) Conclusion: Concomitant antacid use could modify the activity of ICIs in NSCLC patients.
