objective(s) due to increasing emergence of drug-resistance in helicobacter pylori isolates, traditional plants are potentially valuable sources of novel anti-h. pylori agents. in this research, anti-h. pylori activity of the organic extracts of twenty native iranian plants was determined against ten clinical isolates of h. pylori. materials and methods disc diffusion was used to determine the ...

H. pylori infection is usually acquired in early childhood. Its role in gastrointestinal and extra intestinal complaints and serious consequences in adulthood make it as challenging issues. Despite different clinical presentations, in most children, the presence of H. pylori infection does not lead to clinically apparent disease, even when it causes chronic active gastritis. Some of most import...

Fifteen patients with type B gastritis caused by Helicobacter pylori infection were treated with 'triple' therapy consisting of colloidal bismuth subcitrate, amoxycillin, and metronidazole. All were followed up as outpatients every three months for at least one year. After 'triple' therapy a significant (p less than 0.01) and persistent reduction in IgA and IgG antibody levels against H pylori ...

BACKGROUND & AIMS Helicobacter pylori infection was recently associated with iron-deficiency anemia. The aim of this study was to examine the relationship between H. pylori infection, hemoglobin, and iron status using serum ferritin as a marker for total body iron. METHODS Serum ferritin, hemoglobin, and immunoglobulin G (IgG) antibodies against H. pylori were assessed in 2794 Danish adults w...

Considering the role of lectin-carbohydrate interactions between Helicobacter pylori bacteria and the host cells we addressed the question on how mannose binding lectin - MBL, present in human plasma, may influence the phagocytosis of H. pylori by peripheral blood granulocytes. For phagocytosis assay the granulocytes separated from peripheral blood of healthy H. pylori-seronegative donors were ...

Multiple invasive and noninvasive tests for detecting Helicobacter pylori infection are available. The current "gold standard" for the diagnosis of H. pylori infection requires histology and the rapid urease test. Our aim was to test the performance of immunoglobulin A (IgA) and IgG immunoblot assays in comparison with that of the gold standard tests for the diagnosis of H. pylori infection. Ni...

BACKGROUND Helicobacter pylori infection is a major cause of gastric diseases. The clinical implications of H. pylori infection in various diseases outside the gastrointestinal system have also been reported, including in some respiratory disorders. In this study, we investigated the seroprevalence of H. pylori in patients with mild to moderate COPD in an Asian country with a high prevalence of...

Serological testing for immunoglobulin G (IgG) antibodies to Helicobacter pylori has proven useful in supporting the diagnosis of infection with this organism, but the clinical value of IgA antibodies in H. pylori-related gastritis remains controversial. The purpose of our study was to determine the frequency of IgA-positive IgG-negative patients with symptoms of gastrointestinal (GI) disorders...
