Meta-Analysis
The effects of proton pump inhibitors (PPI) depend on metabolic enzyme that has different activity due to gene polymorphism. The purpose of this meta-analysis is to determine the potential effects of polymorphism on the efficiency of PPI-based treatment. The PubMed, EMBASE, Cochrane Library, etc. were searched for relevant articles published in English or Chinese from inception to 31 May 2020. Finally, 26 randomized controlled trials and 15 cohort studies met the inclusion criteria and used for the meta-analysis via STATA version 15. Poor metabolizer (PM) genotype eradication rates were highest for Asian individuals receiving triple or quadruple first-line therapy based on PPIs (p < 0.05). polymorphism could influence eradication rate only in Mainland China and Japan (p < 0.05). PM genotype facilitates the elimination of in Asian populations. Rabeprazole-, esomeprazole- and pantoprazole-based eradication program was less affected by the polymorphism.

BACKGROUND
Spontaneous bacterial peritonitis (SBP) is one of the most common infectious diseases in patients with cirrhosis and is associated with serious prognosis. A prevailing dogma posits that SBP is exacerbated by the frequent use of proton pump inhibitors (PPIs).
AIMS
To re-assess the association between PPIs use and SBP incidence with larger and better-quality data.
METHOD
The studies were identified by searching Proquest, Medline, and Embase for English language articles published between January 2008 and March 2020 using the following keywords alone or in combination: anti-ulcer agent, antacid, proton pump inhibitor, proton pumps, PPI, omeprazole, rabeprazole, lansoprazole, pantoprazole, esomeprazole, peritonitis, spontaneous bacterial peritonitis, SBP, ascites, cirrhosis, ascitic and cirrhotic. Three authors critically reviewed all of the studies retrieved and selected those judged to be the most relevant. Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was followed. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Sub-group analyses were done to decrease the heterogeneity.
RESULTS
A total of twenty-three studies: seven case-control, and sixteen cohorts, involving 10,386 patients were analyzed. The overall results showed a statistically significant association between SBP and PPIs use (pooled odds ratio (OR): 1.80, 95% CI of 1.41 to 2.31). Substantial heterogeneity was observed. On subgroup analysis involving cohort studies, the association was weaker (OR: 1.55 with 95% CI of 1.16 to 2.06 p < 0.00001) but still statistically significant and with high heterogeneity (Chip = 57.68; I = 74%). For case-control studies, the OR was 2.62 with a 95% CI of 1.94 to 3.54. The funnel plot was asymmetric and Egger's test confirmed asymmetry suggesting publication bias (intercept = - 0.05, SE = 0.27, P = 0.850 two-tailed).
CONCLUSION
This meta-analysis sheds light on the conflicting results raised by previous studies regarding the association of SBP with PPIs use. Our meta-analysis showed that there is a weak association, although statistically significant, between SBP and PPIs use. However, the magnitude of the possible association diminished when analysis focused on higher quality data that were more robust. Thus, this updated meta-analysis suggests judicious use of PPIs among cirrhotic patients with ascites.

BACKGROUNG
For a long time, laryngopharyngeal reflux disease (LPRD) has been treated by proton pump inhibitors (PPIs) with an uncertain success rate.
AIM
To shed light the current therapeutic strategies used for LPRD in order to analysis the rationale in the LPRD treatment.
METHODS
Three authors conducted a PubMed search to identify papers published between January 1990 and February 2019 about the treatment of LPRD. Clinical prospective or retrospective studies had to explore the impact of medical treatment(s) on the clinical presentation of suspected or confirmed LPRD. The criteria for considering studies for the review were based on the population, intervention, comparison, and outcome framework.
RESULTS
The search identified 1355 relevant papers, of which 76 studies met the inclusion criteria, accounting for 6457 patients. A total of 64 studies consisted of empirical therapeutic trials and 12 were studies where authors formally identified LPRD with pH-monitoring or multichannel intraluminal impedance-pH monitoring (MII-pH). The main therapeutic scheme consisted of once or twice daily PPIs for a duration ranged from 4 to 24 wk. The most used PPIs were omeprazole, esomeprazole, rabeprazole, lansoprazole and pantoprazole with a success rate ranging from 18% to 87%. Other composite treatments have been prescribed including PPIs, alginate, prokinetics, and H Receptor antagonists.
CONCLUSION
Regarding the development of MII-pH and the identification of LPRD subtypes (acid, nonacid, mixed), future studies are needed to improve the LPRD treatment considering all subtypes of reflux.

A comprehensive systematic review on whether proton pump inhibitors (PPIs) are associated with tuberculosis (TB) incidence is lacking. To conduct a systematic review to elucidate if there is an association between PPI use and TB risk. We searched the MEDLINE, EMBASE, and Cochrane Library databases from their inception through 14 February 2018. Risk of Bias Assessment tool for Non-randomised Studies (ROBANS) was used to estimate the quality of each study. We could not undertake a meta-analysis because of the small number of studies and the diversity of outcome measures. All results of included studies are described narratively. Five studies were identified. In three case-control studies, compared with non-PPI use, PPI use was associated significantly with TB incidence, a 1.2-to-1.7-fold increased risk (adjusted OR 1.29; 95%CI 1.29-1.30, OR 1.31; 95%CI 1.22-1.41, adjusted hazard ratio 1.71; 95%CI 1.17-2.50). A cohort study reported that ≥3 months of PPI treatment was not associated significantly with TB incidence compared PPI treatment of <3 months. One cohort study reported that lansoprazole use decreased TB development significantly when compared with omeprazole/pantoprazole use. Compared with non-PPI use, PPI use was associated significantly with TB risk but the studies were heterogeneous.
