Changes in the severity of gastric mucosal inflammation associated with Helicobacter pylori in humans coinfected with intestinal helminths.

Background: Though a few studies in animal models suggest that intestinal helminths (IH) favorably affect evolution of gastritis associated with Helicobacter pylori (H. pylori) the studies supporting this concept in humans are only a few and are based on serological data.

Methods: To evaluate the possible influence of IH on the human gastric mucosa, three groups of Venezuelan adults with gastropathy (endoscopically diagnosed) were studied: H.

Association between Helicobacter pylori and intestinal parasites in an Añu indigenous community of Venezuela.

Background: Helicobacter pylori (Hp) and enteroparasite infections are highly prevalent in populations with poor living conditions, like the Amerindian communities. Identifying associations between both types of infectious agents could help to detect shared risk factors or transmission routes in these minority ethnic groups. Therefore, the prevalence and association between Hp and enteroparasites were investigated in an indigenous community whose living conditions favor such infectious diseases.
