Helicobacter pylori associated gastric diseases and lymphoid tissue hyperplasia in gastric antral mucosa.
AIM To investigate the relation between Helicobacter pylori associated gastroduodenal diseases and lymphoid tissue hyperplasia in the antral mucosa and to pursue its evolution after eradication of H pylori. METHODS Gastric antral biopsy specimens were obtained from 438 patients with H pylori positive gastroduodenal diseases (185 chronic gastritis, 69 gastric ulcer, and 184 duodenal ulcer) and...
متن کاملExperimental Helicobacter pylori infection induces antral gastritis and gastric mucosa-associated lymphoid tissue in guinea pigs.
Humans infected with Helicobacter pylori have abnormally low levels of the antioxidant vitamin C, which protects against the formation of carcinogenic nitrosamines, in gastric juice. Guinea pigs, like humans and nonhuman primates, have a dietary requirement for vitamin C. As such, these species have gastrointestinal vitamin C transport systems not found in other animals. We have developed and c...
متن کامل[Prognostic impact of Helicobacter pylori infection and eradication therapy in gastric mucosa-associated lymphoid tissue lymphoma].
BACKGROUND Gastric mucosa-associated lymphoid tissue (MALT) lymphoma is associated with Helicobacter pylori infection and H. pylori eradication is used as its first-line therapy. However, controversies exist about the prognostic value of H. pylori infection in these patients. We evaluated the prognostic impact of H. pylori infection and eradication therapy in gastric MALT lymphoma. METHODS A ...
متن کاملResistance of t(11;18) positive gastric mucosa-associated lymphoid tissue lymphoma to Helicobacter pylori eradication therapy.
20-30% of gastric mucosa-associated lymphoid tissue (MALT) lymphoma associated with Helicobacter pylori do not regress after antibiotic therapy. Regression can be assessed only by extended follow-up. To assess whether t(11;18, q21;q21), which results in a chimeric transcript between the AP12 and MLT genes, predicts lymphoma resistance to antibiotic therapy, we screened for the fusion transcript...
متن کاملGenome Sequences of Three Helicobacter pylori Strains from Patients with Gastric Mucosa-Associated Lymphoid Tissue Lymphoma
Most of the published complete genome sequences of Helicobacter pylori strains are limited to clinical isolates associated with gastritis, peptic ulcers, or gastric cancer. The genome sequences of three H. pylori strains isolated from patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma are presented here to facilitate studies of H. pylori-associated MALT lymphomagenesis.
