Abstract

Background: Helicobacter pylori persistence may develop atrophic gastritis, gastric ulcer or cancer.Objectives:To determine the association between the presence of autophagy related gene 16 like 1 and thrionin 300 alanine mutation and H. pylori infection among atrophic gastritis patients.Methods:Gastric biopsy was taken from eighty patients and tested for urease, and blood samples were taken for serum separation for detection of Anti-H. pylori IgG by ELISA and DNA extraction from whole blood were used for sequence specific primer – polymerase chain reaction for autophagy related gene 16 like 1 and thrionin 300 alanine mutation allelic discrimination.Results:Among 40 H. pylori positive cases, the carriers of mutated allele were 62.5% compared with 36.25% in H. pylori negative cases (p = < 0.001, OR = 1.72, CI = 1.23-2.42).Conclusions:Among Iraqi atrophic gastritis, there is an association between H. pylori infection and mutated autophagy related gene 16 like 1 and thrionin 300 alanine mutation allele. Thrionin 300 alanine may confer higher risk for infection with H. pylori.Key words: Autophagy, H. pylori, atrophic gastritis.

Abstract

Background: Helicobacter pylori (H. pylori) infection is associated with gastritis and may induce atrophic gastritis have specific circulating immunoglobulin G (IgG) antibodies.
Aim of the study: To confirm the correlation between Helicobacter pylori infection and gastric atrophy.
Patient and Method: A study was conducted in the period between December 2005 and March 2006 on 25 patients with atrophic gastritis attending Gastroenterology and Hepatology Teaching Hospital in Baghdad, and 25 healthy volunteers who agreed to donate blood. Sera were tested for H. pylori IgG Ab by ELISA test.
Results and Conclusions: detection of H. pylori IgG Ab were applied to each individual, showed that (92 %) of patients with atrophic gastritis had positive H. pylori IgG Ab were as only 4 (16 %) of normal healthy individuals had positive H. pylori IgG Ab.

Abstract

Summary:Background: Chronic atrophic gastritis is a precancerous lesion. A commonly used test for the diagnosis of chronic atrophic gastritis, gastric endoscopy with biopsy collection, and a good serological test would be best include low levels of pepsinogen I (PGI) or a low PGI/PGII ratio. Aim of the study: To confirm the use of serum pepsinogens as a screening marker in atrophic gastritis.Patients and Methods: A study was conducted in the period between December 2005 and March 2006 on 25 patients with atrophic gastritis attending Gastroenterology and Hepatology Teaching Hospital in Baghdad, and 25 healthy control subjects. Sera were tested for PGI and PGII by ELISA test.Results and Conclusions: the serum PGI were decreased significantly with atrophic gastritis and the PGI/PGII ratio were decreased in (78%) of patient group and not affected in healthy people.Key Words: PGI, PGII and Chronic atrophic gastritis.

Abstract

Background: Cytokines are the messengers of the immune system.They are mostly secreted by macrophages and lymphocytes and their production is induced in response to injury or infections.Objective: Biopsy speciemens from the middle body of the stomach were obtained from 18 patients with gastric carcinoma, 32 patients with atrophic gastritis, 50 patients with chronic gastritis and 20 healthy subjects and IL-8 and IL-1B levels were detrmined.Methods: Sandwich-type enzyme-linked immunosorbent assay kit was used to determine the IL-8 and IL-1B levels.Results: IL-8 and IL-1B levels were significantly higher in gastric carcinoma patients than patients with atrophic gastritis and both significantly higher than healthy subjects. Conclusions: IL-8 and IL-1B levels were recommended to be used in differentiation between gastric carcinoma and atrophic gastritis.

Abstract

Chronic Atrophic gastritis (CAG) is a histopathological entity characterized by chronic inflammation of the gastric mucosa with loss of gastric glandular cells and replacement by intestinal-type epithelium and fibrous tissue. Atrophy of the gastric mucosa is the endpoint of chronic processes, such as chronic gastritis associated with Helicobacter pylori infection. This study designed to determine the molecular role of NFkB signaling on Fas receptor mediated apoptosis in H.pylori associated CAG cases. Forty five patients suffering from CAG that proved via endoscopical and histopathological examination were eligible for this study. Males represent (73.33%) and the rest (26.67%) were females with a mean age of 39.26 years .twenty apparently healthy volunteers (10 male and 10 female) with the mean age 38 years and age range (23-58) years were enrolled as control group. Multiple mucosal biopsy specimens were taken from the inflamed area of gastric mucosa for rapid urease test other biopsy specimens were fixed with 10% buffered formalin for preparation of paraffin embedded tissue blocks to prepare slides for histological examination using haematoxylin-eosin stain to evaluate the grades of Polymorphonuclear leukocytes(PMNs) and lymphocytes infiltration . Insitu hybridization technique (ISH) using biotinylated long DNA probe for human NF-KB Gene and for human FAS gene as well as H.pylori Cag A gene were used for detection of NF-KB and Fas mRNA and Cag A mRNA expression in tissue infiltrated lymphocytes and neutrophils as well as gastric epithelial cells and for detection of H.pylori Cag A. This study explained that there was a statistical significant positive linear relationship between lymphocytes grade and Fas mRNA expression in PMNs and gastric epithelial cells. PMN grade has significant positive linear relationship with each of the following markers: Tissue Fas mRNA expression. Tissue NFkB mRNA expression, lymphocytes NFkB mRNA expression, PMN NFkB mRNA expression, Cag A mRNA expression. Lymphocytes Fas mRNA expression has significant positive linear relationship with PMN Fas mRNA expression and Cag A mRNA expression .PMN Fas mRNA expression has significant positive linear relationship with Cag A mRNA expression and negative linear relationship with tissue NFkB mRNA expression . Tissue Fas mRNA expression has significant positive linear relationship with tissue NFkB mRNA expression ; lymphocytes NFkB mRNA expression ; PMN NFkB mRNA expression ;Cag A mRNA expression . Tissue NFKB mRNA expression has significant positive linear relationship with lymphocytes NFkB mRNA expression; PMN NFkB mRNA expression. Lymphocytes NFkB mRNA expression has significant positive linear relationship with PMN NFkB mRNA expression. This study conclude that NFkB play a vital role in determination of immunopathological and inflammatory events of gastritis that leads finally to development of atrophic changes

Abstract

Background/ aim: Chronic atrophic gastritis (CAG) characterized by chronic in-flammation of gastric mucosa with loss of gastric glandular cells and replacement by intestinal-type epithelium and fibrous tissue. CAG may be associated with Helicobacter pylori infection. This study was designed to determine the role of NFkB signaling on Fas receptor mediated apoptosis in H.pylori Cag A+ associated CAG. Methods: According to exclusion criteria (45) CAG patients and (20) control were chosen. Multiple gastric mucosal biopsies were taken for rapid urease test and preparation of slides from paraffin blocks. Slides stained with haematoxylin-eosin for histopathology and grading of PMNs and lymphocytes. Biotinylated DNA probe for human NF-KB and FAS genes were used for detection of their expression in tissue lymphocytes, PMNs and gastric epithelial cells using ISH technique. Biotinylated DNA probe for H.pylori Cag A gene was used for detection of its expression in gastric epithelial cells. Results: lymphocytes grade has positive correlation with Fas mRNA expression in PMN and gastric epithelial cells. PMN grade has positive correlation with tissue Fas mRNA; tissue NFkB mRNA; Cag A mRNA; lymphocytes and PMN NFkB mRNA expression. Lymphocytes Fas mRNA has positive correlation with PMN Fas mRNA and Cag A mRNA expression .Tissue Fas mRNA has positive correlation with tissue NFkB mRNA; Cag A mRNA ,lymphocytes and PMN NFkB mRNA expression. Tissue NFKB mRNA has positive correlation with lymphocytes and PMN NFkB mRNA expression. Conclusion: NFkB play vital role in Immunopathology of H.pylori Cag A+ associated gastritis that leads finally to atrophic changes.
