helicobacter pylori infections are accompanied with the release of some antigenic material into the stool. outer membranes proteins (omp) are among the major antigens of bacteria, which in comparison with other bacterial constituents have less cross-reactivity. in this study, omp of h. pylori were isolated from 11 clinical isolates and rabbit antiserum against them was used to detect possible a...

The aetiology of dyspepsia is unknown in the majority of patients. Helicobacter pylori (H pylori) is the cause in a subset of patients. A non invasive test to assess the presence of H pylori is recommended in the management of patients under the age of 50 presenting to a family practitioner with dyspepsia. A urea breath test or a stool antigen test are the most reliable non invasive tests. Erad...

The [(13)C]urea breath test ((13)C-UBT) and Helicobacter pylori stool antigen test (HpSA) for the diagnosis of H. pylori infection in children were validated. The sensitivity, specificity, and positive and negative predictive values were 93.8, 99.1, 97.8, and 98.0%, respectively, for the (13)C-UBT and 96.9, 100, 100, and 98.0%, respectively, for HpSA. Both tests are appropriate for diagnosing H...

Introduction: Helicobacter pylori (H. pylori) is an important bacterial pathogen, predominantly in undeveloped countries and regions. We conducted this study to investigate the presence of H. pylori antigen in the stool specimens of children, in Tekirdag, Turkey. Material and Methods: Stool specimens of 1441 children aging between 0 month to 15 years, with the complaints of abdominal pain, anem...

background helicobacter pylori (h. pylori) infection usually occurs during childhood, especially in developing countries. the aim of this study was to evaluate the prevalence of h. pylori infection among children in primary schools of rasht, a northern iranian city. methods this cross-sectional study was conducted among 961 primary school students in rasht. samples were randomly selected and st...

Background. Idiopathic thrombocytopenic purpura (ITP) is a bleeding disorder in which the immune system destroys native platelets. In this condition an autoantibody is generated against a platelet antigen. ITP affects women more often than men and is more common in children than adults. Objective. To assess the effect of Helicobacter pylori eradication therapy (HPET) on platelet count in Helico...

Helicobacter pylori infection is one of the most frequent causes of dyspepsia in the general population. As gastrointestinal symptoms are a common complaint among HIV-positive persons, the purpose of the present study is to assess the role of Helicobacter pylori infection in this category of patients. We performed a retrospective, case-control study on two groups of HIV-infected patients admitt...

background: helicobacter pylori is a common cause of chronic infection in human beings. the infection has universal prevalence and contracts all age groups. probably, these bacteria are the cause of the most common chronic bacterial infection in man and have infected approximately half of the world population. the urease of these bacteria degrades the urea in stomach’s mucosa to ammoniac which ...

alkylhydroperoxide reductase (ahpc, the 26 kda antigen) is one of the abundant antioxidant enzymes in helicobacter pylori and seems to have a good potential for use in development of immunoassays to detect h. pylori infection in clinical specimens. this study aimed to investigate some properties of this antigen by the produced monoclonal antibodies. five established hybridoma cell lines secreti...
