[Immune response Th1/Th2 to Helicobacter pylori and Helminths in co-infected patients].

Introduction: Inflammation associated with Helicobacter pylori (H. pylori) infection is linked to the development of a gastric precancerous lesion. Helminth infections could influence the pro-inflam matory response to such infection from LTCD4+ Th1 to a less harmful LTCD4+ Th2 response.

Contrasting serum biomarker profiles in two Colombian populations with different risks for progression of premalignant gastric lesions during chronic Helicobacter pylori infection.

Background: Colombians in coastal Tumaco have a lower incidence of Helicobacter pylori-associated gastric cancer compared to individuals from Tuquerres in the high Andes. This is despite nearly universal prevalence of H. pylori infection and chronic gastritis.
