Resumo: Background Helicobacter pylori has a worldwide distribution and is associated with the pathogenesis of various diseases of the digestive system. Treatment to eradicate this microorganism involves the use of a combination of antimicrobials, such as amoxicillin, metronidazole, clarithromycin, and levofloxacin, combined with proton pump inhibitors. Although the current therapy is effective, a high rate of treatment failure has been observed, mainly because of the acquisition of point mutations, one of the major resistance mechanisms developed by H. pylori. This phenomenon is related to frequent and/or inappropriate use of antibiotics. Conclusion This review reported an overview of the resistance to the main drugs used in the treatment of H. pylori, confirming the hypothesis that antibacterial resistance is a highly local phenomenon and genetic characteristics of a given population can influence which therapy is the most appropriate.

O tratamento para a erradicação deste microrganismo envolve a utilização de uma combinação de agentes antimicrobianos, tais como amoxicilina, metronidazol, claritromicina e levofloxacino, combinados com inibidores da bomba de prótons. Embora a terapia atual seja eficaz, uma elevada taxa de fracasso de tratamento tem sido observada, principalmente devido à aquisição de mutações pontuais, um dos principais mecanismos de resistência desenvolvida por H. pylori, relacionado com o uso frequente e/ou inadequado dos antibióticos. Conclusão Esta revisão abordou uma visão geral da resistência às principais drogas utilizadas no tratamento de H. pylori, confirmando a hipótese de que a resistência bacteriana é um fenômeno altamente local e as características genéticas de uma dada população podem influenciar qual terapia é a mais apropriada.2017-03-14T20:50:19Z2017-03-14T20:50:19Z2016info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfVIANNA, Júlia Silveira et al.
