Background:  There are also reports from other parts of the world indicating the presence of significant association of H. pylori infection and hyperemesis gravidarum, a bothersome condition that affects pregnant women.  Objective: To test the hypothesis that whether H. pylori infection is associated with hyperemesis gravidarum among Iranian H.P carriers. Methods: From November 1999 to February...

Although Helicobacter pylori has a significant impact on the occurrence of severe clinical syndromes, its exact ways of transmission and origin have not been identified. According to the results of some previously published articles, foods with animal origins play a substantial role in the transmission of H. pylori to humans. The present investigation was carried out to study the vacuolating cy...

BACKGROUND/AIMS The role of H. pylori in the pathogenesis of ulcer disease in cirrhotic patients is poorly defined. Therefore, we sought to investigate the prevalence of H. pylori infection and the occurrence of gastroduode-nal lesions in patients with liver cirrhosis. METHODS AND PATIENTS Seroprevalence of H. pylori was tested in 110 patients with liver cirrhosis and 44 asymptomatic patients...

BACKGROUND & AIM The role that H. pylori infection plays in the development of and Barrett's esophagus (BE) is uncertain. We tested the hypothesis that infection with cagA+ Helicobacter pylori strains protects against the development of BE. METHODS We studied 104 consecutive patients, residents in an area with a high prevalence of H. pylori infection, with BE and 213 sex- and age-matched cont...

The prevalence of Helicobacter pylori infection varies between different geographic locations. The objectives of this study were to determine the prevalence of H. pylori infection in patients with gastrointestinal (GI) symptoms and to describe the association of H. pylori infection with demographic data, clinical diagnosis, and previous histories of patients. The study was carried out at the ga...

Background: Rosacea is a chronic skin disease with an unknown etiology. Some reports have suggested an increased prevalence of Helicobacter pylori infection in rosacea patients, but it is controversial. This study was designed to compare the prevalence of H. pylori and serological cag A+ species between the rosacea patients and the healthy control group. Methods: This case-control study was per...

background: blood group antigen binding adhesin ( baba2 ) , is essential for attachment of helicobacter pylori (h. pylori) to the epithelial cell layer and is the most important adhesin of h. pylori . the prevalence rate of the baba2 gene varies in different geographic areas. the aim of this study is to determine the frequency of the baba2 gene in patients with different clinical outcomes. mate...

background: helicobacter pylori infection is the most common gastrointestinal bacterial disease worldwide. although using culture is considered as the golden standard method for diagnosis of h. pylori infection, urea breath test is a notable alternative method because it is an easy, quick, and non-invasive approach. the aim of this study was to estimate the prevalence of h. pylori infection in ...

background : data concerning the information on the prevalence and association of the helicobacter pylori cytotoxinassociated gene a (caga) with disease is still controversial. the aim of this study was to isolate and identify h. pylori by culture methode from biopsy specimens and its relationship with associated diseases by molecular techniques (pcr). materials and methods: gastric biopsy spec...

The facts that H pylori infection is commoner in duodenal ulcer (DU) patients than in the normal population, and that eradication results in most cases being cured, have led to the belief that it causes DU. However, early cases of DU are less likely than established ones to be infected. H pylori-negative cases are usually ascribed to specific associated factors such as non-steroidal anti-inflam...
