RESUMEN

La infección por Helicobacter pylori se constituye como la infección crónica más frecuente en la especie humana. Esta infección se asocia con la patogénesis de enfermedades del estómago como la gastritis, la úlcera péptica duodenal, la úlcera péptica gástrica, el cáncer gástrico y los linfomas tipo MALT del estómago, y una gran variedad de enfermedades extradigestivas incluyendo enfermedades he matológicas, dermatológicas, cardiovasculares y autoinmunes. El diagnóstico de la infección por Helicobacter pylori se puede establecer por métodos invasivos, dependientes de la endoscopia digestiva alta, y por métodos no-invasivos, que no requieren endoscopia, como son la serología, la prueba de aliento con urea marcada con 13C y la detección de antígenos de Helicobacter pylori en materia fecal. En este módulo se analizará la utilización de las pruebas no-invasivas en el diagnóstico y manejo de la infección por Helicobacter pylori, de tal manera que el médico esté en condiciones de solicitar e interpretar adecuadamente las pruebas disponibles en el medio.
