h. pylori infection is usually acquired in early childhood. its role in gastrointestinal and extra intestinal complaints and serious consequences in adulthood make it as challenging issues. despite different clinical presentations, in most children, the presence of h. pylori infection does not lead to clinically apparent disease, even when it causes chronic active gastritis. some of most import...

Background: Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune demyelinating disease in the central nervous system. Association between NMOSD and Helicobacter pylori (H. pylori) infection has been investigated, but few studies have assessed the relationship between H. pylori and seronegative AQP4-Ab NMOSD. Objectives: This study aimed to survey the association between H. pylori...

Introduction: Recent studies have shown a relationship between H. pylori and chronic idiopathic thrombocytopenic purpura (CITP). Objective: The present study was performed to evaluate this relationship in Iranian patients. Methods:  The antibody (IgG) against H. pylori was studied in sixty-two patients with CITP, comprising 25 males and  37 females (mean age: 30.38±12.23 yrs ) The patients posi...

Background: Helicobacter pylori, which is associated with many upper gastrointestinal diseases, is found in half of the population of the world. Several special stains and immunohistochemistry stain for H. pylori are available. The need for and usefulness of immunohistochemical (IHC) technique has been debated for years. Toluidine blue is a simple stain for microbiological studies and is easily...

The aims of this study were to detect Helicobacter pylori (H. pylori) by culture, polymerase chain reaction (PCR) and histopathological methods, to determine the prevalence of active H. pylori infection in Elazig Province, East of Turkey and to evaluate the relationship between H. pylori infection and sex. Antrum and corpus samples of 184 Turkish patients (85 male and 99 female, age range 17 to...

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...

Helicobacter pylori is the causative agent of gastritis and peptic ulcer disease. Eradication of H. pylori is hard to achieve and often require multiple antibiotics regimens. These regimens are quite expensive and have substantial side effects. Licorice is a traditional drug which is frequently used for gastric discomforts in Iran. The susceptibility of H. pylori to the extract of licorice has ...

Background: It is not yet known which types of Toll-like receptors (TLRs) are most effective in Helicobacter pylori (H. pylori) recognition. It is also not known which gastric zones have the most prominent roles in TLR-mediated bacterial recognition. The aim of this work was to analyze the expression of TLR2 and TLR4 in biopsy specimens from H. pylori-infected patients. Methods: Thirty-eight...

introduction and aims: omeprazole is a gastric parietal cells proton pump inhibitor that is also active against h. pylori in vitro. this study was designed to examine the neutralization of h. pylori cytotoxicity on vero cells by omeprazole micronized in strains isolated from gastritis, ulcer, cancer and barrett's ulcer, to determine whether omeprazole can inhibit vacuolation of the vero cells i...
