Background and Aim. It is difficult to master the skill of discriminating gastric adenoma from early gastric cancer by conventional endoscopy or magnifying endoscopy combined with narrow-band imaging, because the colors and morphologies of these neoplasms are occasionally similar. We focused on the surrounding gastric mucosa findings in order to determine how to discriminate between early gastr...
BACKGROUND HIV and Helicobacter pylori are common chronic infections in sub-Saharan Africa. Both conditions can predispose to gastric hypochlorhydria that may be a risk factor for enteric infections and reduced drug absorption. We have investigated to what extent HIV and H. pylori infections are associated with hypochlorhydria in a Malawian cohort of patients undergoing endoscopy. METHODS 104...
Direct diagnosis of gastric cancer with a single laboratory test is impossible. Gastric biomarkers assayed from a blood sample provide, however, a tool to diagnose patients at particularly high risk for gastric malignancy. This possibility is commonly neglected although the biomarkers provide a handy and inexpensive way to rationalize the clinical practices, and to identify the subjects most li...
Background: Infesting nearly half of the world's population, Helicobacter pylori is thought to cause peptic ulcers and gastric adenocarcinoma. Several studies have examined association between H. socioeconomic, clinical, histological factors in pediatric populations. Similarly, this study aimed describe characteristics infection Moroccan children. Methods: Patients aged 1-17 years who underwent...
Higher prevalence of helminth infections in Helicobacter pylori infected children was suggested to potentially lower the life-time risk for gastric adenocarcinoma. In rodent models, helminth co-infection does not reduce Helicobacter-induced inflammation but delays progression of pre-malignant gastric lesions. Because gastric cancer in INS-GAS mice is promoted by intestinal microflora, the impac...
BACKGROUND The best sites for biopsy-based tests to evaluate H. pylori infection in gastritis with atrophy are not well known. This study aimed to evaluate the site and sensitivity of biopsy-based tests in terms of degree of gastritis with atrophy. METHODS One hundred and sixty-four (164) uninvestigated dyspepsia patients were enrolled. Biopsy-based tests (i.e., culture, histology Giemsa stai...
fumonisins, a family of mycotoxins, are mainly toxic and carcinogenic. the present study was carried out to evaluate fumonisin b1 (fb1) effects on the production of inflammatory cytokines by gastric and colon cell lines. the study was performed on two cell lines under in vitro condition, including gastric epithelial cell line (ags) and human colon adenocarcinoma cell line (sw742). lipopolysacch...
