We read with interest the article by Costa et al.[1], investigating the efficacy and tolerability of the culture-guided method detecting the Helicobacter pylori (H. pylori) infection. Apart from the very interesting sort of findings reported by the authors, there are some comments improving the current idea in the treatment of H. pylori in the third-line treatment. In this study, E-test was the susceptibility test used to determine resistant strains. However, relatively high rates of antibiotic resistance to metronidazole and clarithromycin and extremely low rate of resistance to amoxicillin are the point of our discussions. Broadly defined, the E-test is less laborious to conduct than the agar dilution method, but the current findings for those antibiotics must be re-evaluated with a standard method such as agar dilution. As standardization is an inevitable part of designing a useful guideline in the therapy of H. pylori, current results by Costa et al.[1] need to be confirmed by gold standard method [2]. Moreover, the problem is worse about metronidazole as the reliable method is validated to determine the susceptibility of H. pylori isolates to this antibiotic. So far, any therapeutic recommendation that includes metronidazole should be cautiously stated. Antibiotic resistance is not an emerging problem for gastroenterologists anymore as we are facing the dilemma and have no other effective antibiotics on the table. Frequently reported failures in the first and second line therapies of H. pylori are increasing and urgent attention to refining current concept of resistance and therapeutic strategies are required [3]. Clinicians are forced to use ineffective antibiotics, although no susceptibility profile is suggested. Newer formulations in recent guidelines are not well-effective, therefore, new approaches in clinical settings are highly needed [4]. For example, molecular detection is a novel candidate to facilitate detection process. Also, feces sample seems better than biopsy as it is an easy laborious preparation and a noninvasive method and preferable for patients. Last but not least, using developed genetic tools with better proteomics data can help us to design virulent H. pylori strains that are problematic and new therapeutic regimens should only target those strains.
