background: helicobacter pylori (h. pylori), is a common infection in pregnant women accompanied by variations in the levels of the igm, iga and igg antibody isotypes. the variations of anti-h. pylori antibodies during and after pregnancy, and the extent of protection they provide to the mother and the fetus are not completely understood. objectives: to investigate the changes of the anti-h. py...

objective: helicobacter pylori is a widely distributed gram negative bacterium that infects the human stomach and duodenum. some antibiotic regimens are subjected to cure the infection but the cost of drugs, poor patient compliance and emerging of antibiotic-resistant strains are limiting the usefulness of these antibiotic therapies. therefore, interest in developing a h. pylori vaccine is grow...

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...

background: helicobacter pylori infection is one of the most common chronic bacterial infections. there is challenge on the real rate of prevalence of h. pylori in diabetic patients. this study was done to assess the prevalence of h. pylori infection in children suffering from type 1 insulin-dependent diabetes mellitus. methods: in this case-control study, 80 diabetic patients (as the target gr...

Objective(s):Helicobacter pylori infection occurs worldwide, but the prevalence of this infection varies greatly among different countries and population groups. The aim of this study was to determine the seroprevalence of anti-Helicobacter pylori and anti-cytotoxin-associated gene A (CagA) antibodies in asymptomatic healthy population in the center of Iran and to investigate the relation with ...

background helicobacter pylori is responsible for one of the most common human infections and is a major risk factor for stomach ulcer disease and gastric cancer. h. pylori infection has been reported to be associated with generation and development of coronary artery disease (cad). moreover, diabetic patients positive for h. pylori infection showed a higher prevalence of cad compared to h. pyl...

seroepidemiologic studies in developing countries show a high rate of helicobacter pylori (h. pylori) infections in children, in contrast to developed countries. the aim of this study was to evaluate the prevalence of h. pylori in children and teenagers in tabriz, northwest of iran. in this prospective study 44 children and teenagers were randomly selected to study serum igg against h. pylori u...

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 ulcers...

Background: H pylori is a human gastric pathogen. Chemotaxis is an essential factor in colonization of H pylori, but very little is known about its chemotactic responses at different pH conditions, especially in acidic environment of stomach as its natural habitant. Methods: We first determined survival of H pylori under various pH conditions in the presence and absence of urea.  Chemotaxis was...
