1. Comparative proteomics analysis of chronic atrophic gastritis: changes of protein expression in chronic atrophic gastritis without Helicobacter pylori infection
Chronic atrophic gastritis (CAG) is a very common gastritis and one of the major precursor lesions of gastric cancer, one of the most common cancers worldwide. The molecular mechanism underlying CAG is unclear, but its elucidation is essential for the prevention and early detection of gastric cancer and appropriate intervention. A combination of two-dimensio

2. Endoscopic and histopathologic evaluation of the excluded stomach after bariatric surgery / Avaliação endoscópica e histopatológica do estômago excluso após cirurgia bariátrica
The surgical treatment for morbid obesity is the only modality that in the long term obtains the supported loss of weight and maintenance. Vertical banded Roux-en-Y gastric bypass is the most used technique worldwide and in Brazil. Through this technique, the stomach is divided in two assimetrical pouchs, one vertical and tubular with about 5 cm of extension

3. Tumor carcinóide de estômago tipo 1
Gastric carcinoid occurs in less than 1% of gastric neoplasias and around 2% of carcinoids tumors. They are classified into three forms: type 1, associated with atrophic gastritis, type 2, associated with multiple endocrine neoplasia 1 and Zollinger Ellison syndrome, and type 3, a sporadic tumor. This study report a case of gastric carcinoid type 1, which ma

4. Gastric precancerous lesions and Helicobacter pylori infection in relatives of gastric cancer / PrevalÃncia de lesÃes precursoras do cÃncer gÃstrico e do Helicobacter pylori em familiares de pacientes com cÃncer gÃstrico
Infection by Helicobacter pylori, a bacterial species classified by WHO as being carcinogenic (group I) affects more than half the world population. First-degree relatives to patients with gastric cancer are at increased risk of developing gastric cancer. The present study evaluated the prevalence of precursor lesions of gastric cancer and infection by Helic

6. Absence of pepsinogen A3 gene expression in the gastric mucosa of patients with gastric cancer.
AIMS--To investigate the expression of pepsinogen A3 (Pg3) encoding genes in the gastric mucosa of normal controls and subjects with atrophic gastritis and gastric cancer. METHODS--One hundred and fifty nine patients underwent upper gastrointestinal endoscopy with sampling of gastric biopsy specimens and serum. Pg3 isoproteins were determined by electrophore

7. Types of atrophic gastritis in patients with primary Sjögren's syndrome.
Histological examination of the gastric mucosa was performed in 44 patients with primary Sjögren's syndrome with extraglandular symptoms (mean age 51.9, range 22-76). Biopsy specimens were taken from each of three separate regions: the antrum, the corpus, and the transitional zone between the antrum and the corpus. The incidence of chronic atrophic gastriti

8. Positive Result by Serology Indicates Active Helicobacter pylori Infection in Patients with Atrophic Gastritis
Patients with atrophic corpus gastritis and elevated Helicobacter pylori antibody titers but 13C-urea breath test (13C-UBT) and histology results negative for H. pylori were randomized into eradication therapy or follow-up only. Antibody levels decreased significantly in six out of seven patients in the eradication group, while in the follow-up group, the ti

9. The endotoxin of Helicobacter pylori is a modulator of host-dependent gastritis.
Atrophic gastritis caused by Helicobacter pylori is the precursor lesion in the development of intestinal-type gastric adenocarcinoma. In animal models, atrophic gastritis induced by Helicobacter felis has been shown to be host dependent, developing in some mouse strains and not in others. The lipopolysaccharide (LPS) of H. pylori has been suggested to play

10. Age-Dependent Accuracy of Helicobacter pylori Antibody Assays for Adults, with Special Emphasis on Atrophic Gastritis
The accuracy of Helicobacter pylori antibody assays for 561 consecutive adult outpatients who had undergone gastroscopy was studied. The sensitivity of an immunoglobulin G test was 99 to 100% for all age groups, but the specificity declined by age group, from 99% for those aged 15 to 49 years to 75% for those aged ≥65 years. The exclusion of false-positive

11. Five year follow-up study of gastritis.
This paper describes a five year follow-up study of the incidence and course of gastritis affecting the antrum and body of the stomach of 50 patients, most of whom presented with non-ulcer dyspepsia and a few with peptic ulceration. We have shown that antral gastritis, like gastritis affecting the fundus, becomes more severe in a proportion of patients as ti

12. Risk of gastric carcinoma in patients with mucosal dysplasia associated with atrophic gastritis: a follow up study.
AIMS: To assess the risk of gastric carcinoma in patients with histologically verified dysplasia and atrophic gastritis of the stomach. METHODS: One hundred and one patients with mild (n = 84), moderate (n = 14), or severe (n = 3) dysplasia among 359 elderly men who smoked underwent gastroscopy because of low serum pepsinogen. Patients with dysplasia were pr
