Background: Asthma is a highly prevalent chronic respiratory disease in children. Moreover, the underlying causes of asthma exacerbation are important because they are effective in controlling and preventing asthma. The aim of this study was to evaluate the helicobacter pylori infection in controlled and uncontrolled asthmatic children compared to healthy children. Methods: This case- contro...

background: ( h.pylori ) infection is a common bacterial infection in humans. approximately half of the helicobacter pylori people throughout the world are infected by this gastric microbial pathogen. the outcome of h.pylori infection varies from gastritis to peptic ulcers, duodenal ulcers and gastric malignancies. this study aims to estimate the prevalence of h.pylori infection and iron defici...

conclusions there was a significant correlation between crs and presence of h. pylori in sinonasal mucosa. this relationship may reflect the role of h. pylori as one of the pathogenic factors in the development of crs. however, further studies are required to confirm this role. results nine patients (18%) with crs had h. pylori isolated from their samples whereas in the control group, h. pylori...

background: helicobacter pylori is the most common cause of chronic infection in the human stomach. the infection has universe prevalence in all age groups. probably, this bacterium is the cause of most common chronic bacterial infection in human beings and infects approximately half of the world population. h. pylori produces urease, an enzyme that degrades the urea in the stomach’s mucous to ...

background since the discovery of helicobacter pylori, several clinical reports have demonstrated that h. pylori infection has emerged as a new cause of refractory iron stores in children. we carried out a systematic literature review to primarily evaluate the existing evidence on the association between childhood h. pylori infection and iron deficiency anemia (ida) and secondly, to investigate...

background: infection with helicobacter pylori might be related to chronic gastritis, peptic ulcer and gastric adenocarcinoma. given the high prevalence of helicobacter infection in our region, this study was designed to determine the age trend of helicobacter pylori contamination in golestan province in 2008. materials andmethods: this cross-sectional descriptive study was carried out on 1028 ...

background and objective: long period risk of gastric carcinoma in people affected with chronic helicobacter pylori gastritis is 5 times more than normal people. perhaps histological changes due to helicobacter pylori infection could be used for screening people at risk of gastric carcinoma and peptic ulcer. materials and methods: this study has been carried out as a cross-sectional process and...

conclusions: about half the population in iran is infected with helicobacter pylori, the pollution in different areas and preventive strategies should be carried out to control this infection. the prevalence rate of helicobacter pylori infections in iran showed only little changes during the years 1994 to 2011. results: among the 30 studies evaluated, the prevalence rate of helicobacter pylori ...

The aim of this study was to explore the prevalence of Helicobacter pylori infection in different surgical diseases in patients with six different cancer types. We analyzed sixty consecutive patients with malignancy (gastric cancer, pancreatic cancer, hepatocellular cancer, intestinal cancer, colon cancer, rectal cancer). Detection of specific IgA and IgG antibodies to Helicobacter pylori in hu...
