Helicobacter pylori (HP) is the most widely chronic human infection around the world, and the main risk factor for the development of gastric cancer. Our country has high rates of this neoplasia and a high prevalence of HP infection. Even both have fallen in the last year, is a major concern to diagnose the population infected with HP in early stages, before the development of premalignant lesions and properly eradicate this infection. In this review, we discussed the different methods for the diagnosis of HP and factors that change positivity as the use of proton pump inhibitors. Also, we discussed the factors to be considered in the choice of the treatment, like local resistance to antibiotics, specially clarithromycin. In the last years has been documented in Chile a significant increase in resistance to clarithromycin, from 20 to 46%, which predicts inadequate effectiveness for the classic triple therapy. As the result of the previous analysis we discussed new possible therapies, including bismuth quadruple therapy and concomitant therapy. (AU)
