Relation between Helicobacter pylori cagA Status and Risk of Peptic Ulcer Disease (2002)
Nomura, Abraham M. Y., Pérez-Pérez, Guillermo I., Lee, James, Stemmermann, Grant, Blaser, Martin J.
Although colonization with any Helicobacter pylori strain is associated with peptic ulcer, it is uncertain whether the risk is greater with cagA+ or cagA− strains, which differ in their...
Helicobacter pylori and Atrophic Gastritis: Importance of the cagA Status (1995)
Kuipers, Ernst J., Pérez-Pérez, Guillermo I., Meuwissen, Stephan G. M., Blaser, Martin J.
Background: Infection with Helicobacter pylori is a major risk factor for the development of atrophic gastritis and gastric cancer. H. pylori strains can differ with respect to the presence of cagA...
Helicobacter pylori Heat Shock Protein A: Serologic Responses and Genetic Diversity
Ng, Enders K. W., Thompson, Stuart A., Pérez-Pérez, Guillermo I., Kansau, Imad, Van Der Ende, Arie, Labigne, Agnès, ...
Helicobacter pylori synthesizes an unusual GroES homolog, heat shock protein A (HspA). The present study was aimed at an assessment of the serological response to HspA in a group of Chinese patients...
Romero-Gallo, Judith, Pérez-Pérez, Guillermo I., Novick, Richard P., Kamath, Patrick, Norbu, Tsering, Blaser, Martin J.
Although Helicobacter pylori is a cosmopolitan colonizer of the human stomach, the responses among persons in remote populations from whom H. pylori was cultured have not been studied. We report on...
Transient and Persistent Helicobacter pylori Colonization in Native American Children
Pérez-Pérez, Guillermo I., Sack, R. Bradley, Reid, Raymond, Santosham, Mathuram, Croll, Janne, Blaser, Martin J.
Helicobacter pylori is chiefly acquired in childhood, but the exact timing of acquisition is not well understood. The main goal of this study was to assess H. pylori acquisition in a pediatric...
Age-Specific Immune Response to HspA in Helicobacter pylori-Positive Persons in Mexico
Eamranond, Peter P., Torres, Javier, Muñoz, Onofre, Pérez-Pérez, Guillermo I.
The immune response to heat shock protein A (HspA) in Helicobacter pylori-positive adults increases with age in developed countries. This response has not been studied with children or in developing...
