UNLABELLED The aim of the study was to evaluate the expression of EGFR and Bcl-2 proteins as inhibitory markers of apoptosis in surface epithelial cells and gland cells of antral gastric mucosa in children infected with Helicobacter pylori according to the severity and activity of antral gastritis and to assess the correlation between the number of cells expressing EGFR and the number of cells ...

The seroprevalence and incidence of Helicobacter pylori infection were determined among 312 North American missionaries who were serving in developing countries between 1967 and 1984. The majority (81%) resided in sub-Saharan Africa. When initially evaluated, the missionaries had a mean age of 40 years, 65% were female, and all were of white race/ethnicity. An ELISA showed that the initial prev...

OBJECTIVE Although the diagnostic utility of serum IgG antibodies to Helicobacter pylori (H. pylori) is well established, the usefulness of IgA-based tests is less well documented. The aim of this study was to evaluate two commercially available ELISAs, both for IgG and IgA. PATIENTS AND METHODS Rapid urease test and histology analysis were performed in 183 patients. A patient was considered ...

This work aimed to determine whether seropositivity to Helicobacter pylori infection was an independent risk factor for hyperhomocysteinemia patients with cardiovascular disease. The H. pylori IgG, IgA and homocystein levels in 96 patients with cardiovascular disease and 64 participants free of cardiovascular disease as control subjects were determined by ELISA assay. The results showed that se...

Background: Helicobacter pylori is the most common chronic bacterial infection, and a significant etiological factor in acid peptic diseases and gastric cancer. Dyspepsia is a common gastrointestinal disorder, and the most common indication for gastroscopy. Detection of H. pylori during endoscopy has become standard clinical practice. Elevated levels of inflammatory markers such as C-reactive p...

Background: Helicobacter pylori infection is one of the most common gastrointestinal infections worldwide. Predominant T-helper 1 (Th1) responses with increased gamma interferon (IFN- γ) levels have been proposed to play an important role in H. pylori-induced peptic ulcer. However, bacterial factors contributing to the initiation of Th1 polarization of H. pylori-specific immune responses have n...

background helicobacter pylori infection is a common infection that affects human beings. this infection also affects children. different diagnostic methods such as serology, stool antigen detection, rapid urease test and histology are used to detect this microorganism. objectives the aim of this study was to determine the correlation between serology and histology/rapid urease test. patients a...

Helicobacter pylori is thought to be related to atherosclerosis and aneurysm development. We aimed to detect virulance factors of H. pylori and examine the potential etiopathogenetic relationship between aortic aneurysm and H. pylori, 58 abdominal aortic aneurysm (AAA) and 38 ascending aortic aneurysm (AsAA) cases and 57 Healty control group (HCG) were included. We investigated H. pylori IgG by...

background: the optimal treatment is not possible yet for chronic prostatitis due to the unknown etiology of the diseases. we aimed to investigate the association of helicobacter pylori infection with chronic prostatitis. methods: in this prospective case-control study that conducted in imam hospital complex affiliated to tehran university of medical sciences in tehran, iran from 2014 to 2015, ...
