Abstract Helicobacter pylori is a widespread disease causing most of the peptic ulcer diseases and low-grade mucosa-associated lymphoreticular tissue (MALT) lymphoma. Moreover, H. pylori is a proven environmental risk factor for gastric carcinoma and it has been recognized as a type 1 carcinogen factor.

Abstract

Abstract Helicobacter pylori is a widespread disease causing most of the peptic ulcer diseases and low-grade mucosa-associated lymphoreticular tissue (MALT) lymphoma. Moreover, H. pylori is a proven environmental risk factor for gastric carcinoma and it has been recognized as a type 1 carcinogen factor. A combination of drugs has been proposed, using a proton pump inhibitor (PPI), amoxicillin, clarithromycin, metronidazole and tetracycline to treat the infection. Since 1996, according to the European guidelines, the first-line approach using PPI, amoxicillin and clarithromycin or metronidazole has been suggested. Seven days of quadruple therapy with PPI (or ranitidine), tetracycline, bismuth salts and metronidazole has been reserved as second-line treatment. To improve the eradication rate of the triple therapy, a different combination of the available antibiotics has been proposed, consisting of a 10-day sequential regimen. A second-line levofloxacin- amoxicillin-based triple therapy given for 10 days has been proposed, obtaining a high eradication rate, suggesting this regimen to be a suitable retreatment option in eradication failure. A third-line treatment with rifabutinbased regimen has been proposed
