- Gastric MALT lymphomas: The value of biopsy performed routinely during endoscopic evaluation. Dore, M.P.; Pironti, A.; Marras, L.; Maragkoudakis, E.; Manca, A.; Massarelli, G.; Realdi, G. // Gut;Sep2002 Supplement 2, Vol. 51, pA106
Background: The discovery of a relation between gastric MALT lymphomas and infection caused by H. pylori has profoundly influenced our approach to their management. The clinical manifestations of MALT lymphomas are not specific and their endoscopic appearance range from normal gastric mucosa to...
- Tejido linfoide y linfomas gÃ¡stricos. López, Rocío del Pilar P.; Andrade, Rafael Enrique P. // Revista Colombiana de GastroenterologÃa;Oct2010, Vol. 25 Issue 4, p409
In this review we describe various aspects of the primary gastric lymphomas, the classification, and the most important clinico-pathological aspects, with emphasis in mucosa associated lymphoma (MALT) and the Helicobacter pylori infection.
- Cure of Helicobacter pylori infection and duration of remission of low-grade gastric mucosa-... Neubauer, Andreas; Thiede, Christian // JNCI: Journal of the National Cancer Institute;09/17/97, Vol. 89 Issue 18, p1350
Studies the links between the cure of Helicobacter pylori infection and duration of remission of low-grade gastric mucosa-associated lymphoid tissue lymphoma. Determination of whether patients in complete remission displayed evidence of residual monoclonal B cells.

- The occupational risk of Helicobacter pylori infection among gastroenterologists and their assistants. Peters, Claudia; Schablon, Anja; Harling, Melanie; Wohlert, Claudia; Costa, José Torres; Nienhaus, Albert // BMC Infectious Diseases;2011, Vol. 11 Issue 1, p154
Background: Helicobacter pylori is a widely spread bacterium that mainly inhabits the gastric mucosa and can lead to serious illnesses such as peptic ulcer disease, gastric carcinoma and gastric MALT lymphoma. The oral-oral route seems to be the main transmission route. The fact that endoscopes...
- Helicobacter pylori and hetertopic gastric mucosa in the upper esophagus (the inlet patch). Gutierrez, Oscar; Akamatsu, Taiji; Cardona, Hector; Graham, David Y.; El-Zimaity, Hala M.T. // American Journal of Gastroenterology;Jun2003, Vol. 98 Issue 6, p1266
: ObjectivesHelicobacter pylori (H. pylori) may colonize gastric mucosa wherever it is found in the GI tract. Heterotopic gastric mucosa in the upper esophagus (inlet patch) is a potential site for H. pylori infection and may provide a reservoir for oral-oral transmission or a niche where...
- Expression of Interleukin-18, a Th1 Cytokine, in Human Gastric Mucosa Is Increased in Heliobacter pylori Infection. Tomita, Toshihiko; Hida, Nobuyuki; Robinson, Philip A.; Crabtree, Jean E.; Jackson, Andrew M.; Hayat, Mumtaz; Dixon, Michael F.; Shimoyama, Takashi; Axon, Anthony T. R. // Journal of Infectious Diseases;2/15/2001, Vol. 183 Issue 4, p620
Features a study on the effect of Helicobacter pylori infection on gastric mucosal interleukin-18 (IL-18) and caspase-1. Details on IL-18; Patients and methods; Expression of caspase-1 protein in gastric mucosa; Discussion.
- Long-term effects of Helicobacter pylori eradication in Mongolian gerbils. Hirayama, Fumihiro; Takagi, Shiro; Yokoyama, Yoshito; Yamamoto, Katsuhiro; Iwao, Eiji; Haga, Keiichiro // Journal of Gastroenterology;2002, Vol. 37 Issue 10, p779
Background. In this study, to clarify whether Helicobacter pylori eradication alters the course of the development of gastric mucosal changes in the stomach, we examined the long-term effects of H. pylori eradication on H. pylori-inoculated gerbils. Methods. A total of 40 H. pylori-inoculated...
- Association between infection with Helicobacter pylori and risk of gastric cancer: evidence from a prospective investigation. Forman, D.; Newell, D.G.; Fullerton, F.; Yarnell, J.W.G.; Stacey, A.R.; Wald, N.; Sitas, F. // BMJ: British Medical Journal (International Edition);6/1/91, Vol. 302 Issue 6788, p1302
Investigates the association between gastric cancer and prior infection with Helicobacter pylori in Great Britain. Examination of gastric biopsy specimens; Presence of concentrations of IgG antibodies; Influence of social class on H. pylori infection.
