Purpose: We aimed to conduct an updated systematic review and network meta-analysis (NMA) to estimate the efficacy of Helicobacter pylori (H. pylori) treatment strategies in Arab countries. Methods: We systematically searched PubMed, Scopus, Web of Science (WOS), EBSCO, and EMBASE from inception to July 18, 2020, using boolean operators. Retrieved articles were screened, and relevant data were extracted. We used R programming software to analyze extracted data. Results: Fifty-four articles (n= 7829 patients) were included in the NMA. Pooled overall analysis demonstrated that adjuvant therapy (standard triple or sequential therapy plus another adjuvant drug) was the best treatment with higher odds of eradication rate [OR= 6.42, 95% CI (1.37: 30.05), P-score= 0.21]. Moreover, Seqential therapy (SQT) and Quinolone based therapy (QBT) were associated with higher eradication rate compared to other regimens [OR= 4.83, 95% CI (1.49: 15.64), P-score= 0.30] and [OR= 4.32, 95% CI (1.15: 16.16), P-score= 0.36], respectively. In adults, the efficacy of QBT was higher than other stratigies in terms of H. pylori eradication [OR= 2.00, 95% CI (1.09, 3.69), P score= 0.19]. In naïve population, QBT and SQT were associated with substantial eradication rate [OR= 1.94, 95% CI (1.19: 3.16), P score=0.19] and [OR= 1.66, 95% CI (1.10: 2.50), P score=0.33], respectively. Conclusion: Our findings suggest that standard triple or sequential therapy plus another adjuvant drug, QBT and SQT therapies were the most effective regimens for eradicating H.pylori in Arab countries.

AbstractObjectiveTo investigate the impact of patient and public involvement (PPI) on rates of enrolment and retention in clinical trials and explore how this varies with the context and nature of PPI.DesignSystematic review and meta-analysis.Data sourcesTen electronic databases, including Medline, INVOLVE Evidence Library, and clinical trial registries.Eligibility criteriaExperimental and observational studies quantitatively evaluating the impact of a PPI intervention, compared with no intervention or non-PPI intervention(s), on participant enrolment and/or retention rates in a clinical trial or trials. PPI interventions could include additional non-PPI components inseparable from the PPI (for example, other stakeholder involvement).Data extraction and analysisTwo independent reviewers extracted data on enrolment and retention rates, as well as on the context and characteristics of PPI intervention, and assessed risk of bias. Random effects meta-analyses were used to determine the average effect of PPI interventions on enrolment and retention in clinical trials: main analysis including randomised studies only, secondary analysis adding non-randomised studies, and several exploratory subgroup and sensitivity analyses.Results26 studies were included in the review; 19 were eligible for enrolment meta-analysis and five for retention meta-analysis. Various PPI interventions were identified with different degrees of involvement, different numbers and types of people involved, and input at different stages of the trial process. On average, PPI interventions modestly but significantly increased the odds of participant enrolment in the main analysis (odds ratio 1.16, 95% confidence interval and prediction interval 1.01 to 1.34). Non-PPI components of interventions may have contributed to this effect. In exploratory subgroup analyses, the involvement of people with lived experience of the condition under study was significantly associated with improved enrolment (odds ratio 3.14v1.07; P=0.02). The findings for retention were inconclusive owing to the paucity of eligible studies (odds ratio 1.16, 95% confidence interval 0.33 to 4.14), for main analysis).ConclusionsThese findings add weight to the case for PPI in clinical trials by indicating that it is likely to improve enrolment of participants, especially if it includes people with lived experience of the health condition under study. Further research is needed to assess which types of PPI work best in particular contexts, the cost effectiveness of PPI, the impact of PPI at earlier stages of trial design, and the impact of PPI interventions specifically targeting retention.Systematic review registrationPROSPERO CRD42016043808.

Aim: Helicobacter pylori (H. pylori) infection and periodontitis have considerable worldwide prevalence once they both present systemic alterations with a possible association between them. Therefore, we have performed this meta-analysis to assess the possible association between H. pylori infection and periodontitis. Material and Methods: A systematic search in the literature was performed for studies published before December 2, 2019 in diverse scientific and educational databases. The data was extracted by two investigators and the statistical analysis was performed by Review Manager statistical program with heterogeneity and Odds Ratio (OR) with 95% of Confidence Intervals (CI) calculations as well as a sensitive analysis to assess the accuracy of the results. The value of P<0.05 was considered as significant. In addition, we performed the analysis of the quality of included studies as well as the evaluation for risk of bias. Results: In overall analysis, H. pylori infection was associated with the risk of periodontitis development (OR = 1.72, CI: 1.47, 2.02, P<0.00001) and the periodontitis was considered as a risk factor for H. pylori infection (OR = 3.21, CI: 2.31, 4.47, P<0.00001). Moreover, the evaluation of dental plaque from patients with periodontitis reveled increased risk of H. pylori infection (OR = 3.46, CI: 2.39, 5.01, P<0.00001). Conclusions: This current systematic review and meta-analysis composed by 12 studies in 7,059 participants showed that H. pylori infection increased significantly the risk of the development of periodontitis and the periodontitis may be a risk for this bacterial infection.

Abstract Background Conflicting results of recent studies on the association between Helicobacter pylori (H. pylori) infection and the risk of insulin resistance and metabolic syndrome explored the need for updated meta-analysis on this issue. Therefore, this systematic review aimed to estimate the pooled effect of H. pylori infection on the risk of insulin resistance and metabolic syndrome. Methods To identify case-control studies and cohort studies evaluating the association of H. pylori infection with insulin resistance and metabolic syndrome, a comprehensive literature search was performed from international databases including Medline (PubMed), Web of Sciences, Scopus, EMBASE, and CINHAL from January 1990 until January 2021. We used odds ratio with its 95% confidence interval (95%CI) to quantify the effect of case-control studies and risk ratio with its 95%CI for the effect of cohort studies. Results 22 studies with 206911 participants were included for meta-analysis. The pooled estimate of odds ratio between H. pylori infection and metabolic syndrome in case-control studies was 1.19 (95%CI: 1.05, 1.35; I2 = 0%), and in cohort studies, the pooled risk ratio was 1.31 (95%CI: 1.13, 1.51; I2 = 0%). Besides, case-control studies showed the pooled odds ratio of 1.54 (95%CI: 1.19, 1.98; I2 = 6.88%) for the association between H. pylori infection and insulin resistance. Conclusion A positive association was found between H. pylori infection and insulin resistance as well as metabolic syndrome, so planning to eliminate or eradicate H. pylori infection could be an effective solution to improve metabolic syndrome or insulin resistance, and vice versa.
