background: glaucoma is a progressive optic neuropathy and is one of the leading causes of blindness worldwide. different factors have been contributed in the pathogenesis of glaucoma including h. pylori infection. objective: to determine the levels of anti-h. pylori igg antibody in the aqueous humor of patients with pseudoexfoliation and primary open angle glaucoma, in comparison with age and ...

background: helicobacter pylori (h. pylori) infection is thought to play an etiologic role in several gastroduodenal diseases including gastric ulcer, duodenal ulcer, gastric malt lymphoma, and distal gastric cancer. several studies have suggested that h. pylori which express cytotoxin-associated gene a (caga) may be more virulent than those that do not, but limited populations have been studie...

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 (H. pylori) is causally related to chronic active gastritis, peptic ulcer disease, primary low-grade B-cell gastric lymphoma, and is also a risk factor for gastric cancer. In addition, a high seroprevalence of H. pylori has been found in many extragastrointestinal disorders, including active bronchiectasis and chronic obstructive pulmonary disease (COPD). It appears that H. ...

BACKGROUND Higher serological prevalence rates of helicobacter pylori (H. pylori) infection have been reported in patients with type 1 diabetes (T1DM) and autoimmune thyroiditis (AT). Patients with T1DM are at increased risk for developing other autoimmune diseases, most commonly AT. It is unknown whether H. pylori infection could explain the high prevalence of thyroid autoantibodies and AT in ...

background: infections attributed to helicobacter pylori ( h. pylori ) involve almost half of the world's population. one of the effects is auto-antibody induction and cross-reaction with numerous proteins in the body. as a result of its widespread prevalence and importance, this study evaluates the associations between h. pylori and thyroid auto-antibodies. materials and methods: this study en...

We tested correlations between anti-Helicobacter pylori IgG and IgA levels and the urease test, anti-CagA protein antibody, degree of gastritis, and age. In total, 509 children (0-15 years) were enrolled. Subjects were stratified as 0-4 years (n = 132), 5-9 years (n = 274), and 10-15 years (n = 103) and subjected to the urease test, histopathology, ELISA, and western blot using whole-cell lysat...

PURPOSE A prospective, nonrandomized, comparative study was carried out to investigate levels of anti-Helicobacter pylori-specific IgG antibodies in the aqueous humor and serum of patients with primary open angle glaucoma (POAG), exfoliation syndrome [pseudo-exfoliation glaucoma (PXFG)], and with normotensive cataract patients, who served as controls. METHODS Aqueous humor was aspirated at th...

It has been also reported that that H. pylori infection may be responsible for some endocrine disorders, such as autoimmune thyroid diseases, diabetes mellitus and primary hyperparathyroidism. H. pylori which express cytotoxin-associated gene A (CagA) may be more virulent than those that do not. The aim was to evaluate the seroprevalence of anti-H. pylori IgG and anti-CagA  antibodies in patien...

OBJECTIVES Helicobacter pylori infection occurs worldwide, but the prevalence of this infection varies greatly among different countries and population groups. The aim of this study was to determine the seroprevalence of anti-Helicobacter pylori and anti-cytotoxin-associated gene A (CagA) antibodies in asymptomatic healthy population in the center of Iran and to investigate the relation with di...
