Duodenal microbiome in patients with or without Helicobacter pylori infection.

Background: Intestinal microbiota are recognized as an organ with important physiological functions whose alterations have been associated with common diseases including inflammatory intestinal conditions, malnutrition, type-2 diabetes, and cardiovascular diseases. The composition and function of the microbiota in the distal part of the intestine has been mainly described, while there is limited information on the small intestine microbiota. The objective of the present study was to describe the duodenal microbiome in individuals with dyspepsia in the presence or absence of Helicobacter pylori gastric infection.

Effect of Saccharomyces boulardii CNCM I-745 as complementary treatment of Helicobacter pylori infection on gut microbiome.

Conventional therapy for H. pylori infection includes the combination of antibiotics and a proton-pump inhibitor. Addition of probiotics as adjuvants for H.

RISK AND PROTECTIVE FACTORS FOR GASTRIC METAPLASIA AND CANCER: A HOSPITAL-BASED CASE-CONTROL STUDY IN ECUADOR.

Introduction: worldwide, stomach cancer is the fifth most frequent cancer, with 952 000 new cases diagnosed in 2012. Ecuador currently holds the 15th place of countries with the highest incidence of stomach cancer for both sexes.

Objectives: the objective of this study was to evaluate risk and protective factors for gastric cancer/metaplasia.

Improved method for extraction and detection of Helicobacter pylori DNA in formalin-fixed paraffin embedded gastric biopsies using laser micro-dissection.

To assess the molecular events exerted by Helicobacter pylori interacting directly with gastric epithelial cells, an improved procedure for microbial DNA isolation from stained hematoxilin-eosin gastric biopsies was developed based on laser micro-dissection (LM) [1]. Few articles have described the use of LM to select and detect H. pylori genome from formalin-fixed paraffin embedded gastric tissue [2].
