OBJECTIVES To review some aspects of the etiopathogenesis of peptic ulcerous disease especially on the basis of studies on its correlation with Helicobacter pylori (H. pylori). METHODS A search was made in the data bases MEDLINE, LILACS and PubMed, and in Brazilian and foreign books, referring to the incidence and prevalence of infection by H. pylori and of peptic ulcerous disease in various ...

conclusions findings of this study demonstrate no significant difference between levels of h. pylori specific antibodies of iga, igg, anti-caga and the presence of pcos disorders, and also indicate that serologic testing is a sensitive method for the detection of h. pylori antibodies. the high prevalence of h. pylori positive antibody levels in both pcos and non-pcos patients can be probably as...

background: non-steroidal anti-inflammatory drug (nsaid) use and h pylori infection are two major causes of peptic ulcers. this study investigates the effect of h pylori infection and nsaids on gastroduodenal damages and bleeding (gib).   methods: 104 patients with acute gastrointestinal bleeding (gib) and 102 patients with dyspepsia without bleeding were studied. duodenal (du) and gastric ulce...

objective(s) resistance to antimicrobial agents, particularly metronidazole and clarithromycin, is frequently observed in helicobacter pylori and may be associated with treatment failure. this resistance rate varies according to the population studied. the aim of this study was to assess the pattern of antimicrobial resistance of h. pylori isolates from dyspeptic patients in isfahan. materials ...

The role of environmental reservoirs in H. pylori transmission remains uncertain due to technical difficulties in detecting living organisms in sources outside the stomach. Residents of some Canadian Arctic communities worry that contamination of the natural environment is responsible for the high prevalence of H. pylori infection in the region. This analysis aims to estimate associations betwe...

background: helicobacter pylori (h. pylori) infection is thought to play an etiologic role in several gastroduodenal diseases including gastric ulcer, duodenal ulcer, gastric malt lymphoma, and distal gastric cancer. several studies have suggested that h. pylori which express cytotoxin-associated gene a (caga) may be more virulent than those that do not, but limited populations have been studie...

Helicobacter pylori (H. pylori) is one of the most common human infections worldwide particularly in the developing countries. It has been established as etiology of chronic gastritis and peptic ulcer disease, gastric adenocarcinoma and mucosal associated lymphoid tissue lymphoma (MALT). During this decade, there have been some reports showing a decline in global prevalence of H. pylori infecti...

background: otitis media with effusion (ome) is a common disease in children. viral or bacterial infections, allergy, adenoids, functional abnormalities of the eustachian tube, and gastroesophageal reflux might have a possible role in the pathogenesis of ome. however, the exact pathogenesis of ome is still unsettled. objectives: the purpose of this study was to compare helicobacter pylori preva...
