A systematic review and meta-analysis of the role of Helicobacter pylori eradication in preventing gastric cancer
Background Increasing evidence has suggested that Helicobacter pylori (H. pylori) eradication might prevent the development of gastric cancer (GC). Th is systematic review and meta-analysis aimed to better explore the role of H. pylori eradication in preventing GC, with particular reference to patients with precancerous lesions at baseline histology. Methods Searches for human studies were performed through October 2016 and risk ratios (RRs), were obtained. Heterogeneity between studies was estimated using the Cochran Q test and I 2 values, whereas the possibility of publication bias was estimated with funnel plots. Additionally, we performed subgroup and sensitivity analyses. Conclusion H. pylori eradication is associated with a signifi cantly lower risk of GC; this fi nding has signifi cant implications for the prevention of this cancer. Th e benefi t is maximized when H. pylori eradication is applied at early stages of the infection
Helicobacter pylori Diagnostic Tests Used in Europe : Results of over 34,000 Patients from the European Registry on Helicobacter pylori Management
Funding Information: This study was funded by Richen; however, clinical data were not accessible and the company was not involved in any stage of the Hp-EuReg study (design, data collection, statistical analysis, or manuscript writing). We want to thank Richen for their support. This project was promoted and funded by the European Helicobacter and Microbiota Study Group (EHMSG), the Spanish Association of Gastroenterology (AEG) and the Centro de InvestigaciĂłn BiomĂ©dica en Red de Enfermedades HepĂĄticas y Digestivas (CIBERehd).

A systematic review and meta-analysis of the role of Helicobacter pylori eradication in preventing gastric cancer
Helicobacter pylori and Non-malignant Diseases
In recent years, the focus of Helicobacter pylori clinical research has been mainly on gastric malignancy. However, the role of H. pylori in non-malignant diseases, such as peptic ulcer, gastroesophageal reflux disease (GERD) and non-ulcer dyspepsia, as well as non-steroidal anti-inflammatory drug consumption, is still of great interest. A 1- to 2-week course of H. pylori eradication therapy is an effective treatment for H. pylori-positive peptic ulcer disease and a positive CagA status is a predictor for successful eradication of H. pylori. Antral prostaglandin-E2-basal levels appear to be critical for the development of aspirin-induced gastric damage in subjects without H. pylori infection. In clinical practice, among patients treated with proton-pump inhibitors, H. pylori status has no effect on the speed or degree of GERD symptom relief. For the management of dyspepsia in primary care, antisecretory therapy confers a small insignificant benefit compared to strategies based on H. pylori testing while these latter strategies may be cost-effective. H. pylori eradication therapy has a small but statistically significant effect on H. pylori-positive non-ulcer dyspepsia. An economic model suggests that this modest benefit may still be cost-effective but more research is needed

Eradication rates in italian subjects heterogeneously managed for Helicobacter pylori infection. Time to abandon empiric treatments in Southern Europe
Background & Aims: H. pylori eradication is strongly affected by various factors, including the ongoing antibiotic resistance. We describe a Ăąreal lifeĂą scenario in patients managed for H. pylori-related conditions, living in a southern Italian region (Apulia), an area with clarithromycin resistance >15%. Methods: 2,224 subjects were studied in two tertiary referral centers in Apulia. Analyses included: reason for referral, H. pylori infection rates (13C-urea breath test Ăą UBT or upper endoscopy), and eradication rates following distinct regimens previously prescribed or prospectively prescribed (such as the bismuth-based quadruple therapy PyleraĂÂź, recently marketed in Italy). Results. Over 80% of the patients were referred by family physicians (60% naĂÂŻve subjects). The overall infection rate was 32.5% and it was similar in asymptomatic patients (31.1%) or with H. pylori-related symptoms/clinical conditions (34.3%). In the 987 H. pylori+ve patients receiving therapy, the overall eradication rate was 80.2% (ITT). Observed eradication rate varied greatly across different regimens: 57.1% (2nd line levofloxacin), 59.6% (unconventional), 70.7% (7-day triple), 73.2% (7-day undefined), 89% (10-day sequential) and 96.9% (ITT, 10 day PyleraĂÂź, 1stto 5thline regimens given to 227 patients). Conclusions. A heterogeneous Ăąreal lifeĂą scenario in Southern Europe shows that H. pylori+ve patients are put at risk of poor outcomes and points to the need of a susceptibility-based therapy according to guidelines and local microbial resistance. In the present setting (i.e. high clarithromycin resistance), despite the high observed eradication rate, sequential therapy should not be recommended (absent in guidelines, unneeded antibiotic). Bismuth-based quadruple treatment (1st, 2ndor subsequent lines) yields the highest eradication rates
