BACKGROUND/AIMS There is no generally accepted model for Helicobacter pylori infection in humans. The aim of this study was to examine the natural history and effect of treatment in rhesus monkeys and sequentially define the immune response to H. pylori in relation to treatment. METHODS Infection and gastritis were graded blindly by histological analysis and culture of biopsy specimens harves...

conclusions: the result of our study showed that using clarithromycin, amoxicillin and omeprazole for treatment of h. pylori infection can be useful. it is concluded from lower levels of igg and caga in blood and h. pylori antigen in stool after treatment compared to the amount of these factors before therapy. considering all these data, it is obvious that there is an urgent need to found a bet...

In this cross-sectional study, we evaluated H. pylori seroprevalence and the relevant factors in 1518 people aged > or = 6 years from the general population of Nahavand, western Islamic Republic of Iran. Questionnaires covering sociodemographic variables were completed by interview. Blood samples were taken from each individual. Sera were tested for anti-H. pylori IgG using commercial enzyme im...

BACKGROUND Helicobacter pylori, an infective agent of more than 50% of the world population is prominent to be the main causative factor in the etiologies of chronic, active or type B gastritis, peptic and duodenal ulcer, gastric carcinoma, and mucosa-associated lymphoid tumors. A high prevalence of this bacterium in dental plaque is always reported. Pharmacological treatment of H. pylori infec...

objective: helicobacter pylori (h. pylori) is the most common pathogenic bacteria in the stomach. the aim of the current study was to explore the effect of oral garlic administration on bacterial urease activity inside the stomach and its contribution to the treatment of h. pylori infection.   materials and methods: in this clinical trial, 15 patients were studied quantitatively with urease bre...

AIMS To clarify the relation between the serum titre of anti-Helicobacter pylori (H pylori) antibody and the extent of intestinal metaplasia of the gastric mucosa. METHODS The serum anti-H pylori IgG titres of 95 asymptomatic individuals (mean age 65 years) undergoing an annual health examination were measured and compared with the extent of intestinal metaplasia (absent, moderate, or extensi...

Objective(s): Treatment of Helicobacter pylori infection by common drugs may be associated with several problems such as antimicrobial resistance to commonly used antibiotics and side effects of employed drugs. Therefore, exploration of non-chemical compounds which are safer than chemical ones is becoming important as an alternative therapy. The purpose of this study w...

the aim of this study was to evaluate an enzyme - linked immunosorbent assay (elisa) for the detection of anti - helicobacter pylori (h. pylori) specific igg antibodies in specimens of oral fluid. all subjects over the age 18 years undergoing endoscopy for any reason were asked to participate in the study. two groups of 44 patients in each were selected as hp+ and hp-. at the same time, 5 milli...
