dc.descriptionIn 1982, Marshall and Warren discovered a bacterium that survives in acid and colonizes gastric mucosa called Helicobacter pylori, which is present in patients with gastritis and peptic ulcer. Its prevalence in adults in western countries is between 20 and 40%, and in developing countries approximately 80%. Knowledge of immunological, metabolic and pathogenic characteristics has facilitated progress in the diagnosis and prevention of gastroduode- nal diseases related with it. The infection has been associated with expression of specific alleles HLA-DR human gastrointestinal tract, suggesting a role in the development of chronic gastritis. Currently there are many tests for detection, highlighting the breath test, because the most sensitive and specific. The review aims to highlight the advances in immunogenetics and methods to diagnose this bacterium.en-US
dc.descriptionEn 1982, Marshall y Warren descubrieron una bacteria que sobrevive en medio ácido y coloniza la mucosa gás- trica, llamada Helicobacter pylori, presente en pacientes con gastritis y úlcera péptica; su prevalencia en adultos de países occidentales está entre 20 y 40% y en países en vías de desarrollo en aproximadamente 80%. El conoci- miento de sus características inmunológicas, metabólicas y patogénicas, ha facilitado avanzar en el diagnóstico y prevención de enfermedades gastroduodenales relacionadas con ella. La infección se ha asociado con expresión de alelos específicos HLA-DR del tracto gastrointestinal humano, sugiriendo un papel en el desarrollo de gastritis crónica. Actualmente existen muchas pruebas para su detección, destacándose el test del aliento, por ser la más sensible y específica. El objetivo de esta revisión es el de evidenciar los conocimientos en la inmunogenética de la bacteria y los avances en las metodologías para su diagnóstico.es-ES
