Age-specific immune response to HspA in Helicobacter pylori-positive persons in Mexico

Clin Diagn Lab Immunol. 2004 Sep;11(5):983-5. doi: 10.1128/CDLI.11.5.983-985.2004.

Abstract

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 countries (G. I. Pérez-Pérez, J. M. Thiberge, A. Labigne, and M. J. Blaser, J. Infect. Dis. 174:1046-1050, 1996). As determined by using a specific enzyme-linked immunosorbent assay, HspA seropositivity among 592 individuals in Mexico was <10% in children and increased to >40% in adults.
