With great interest, I read a research article by Le Thi et al.[1], suggesting that a 2-week standard triple therapy with a proton-pump inhibitor (PPI), amoxicillin (AMPC), clarithromycin (CAM) or metronidazole (MTZ) tailored to microbial sensitivity tests can achieve a primary Helicobacter pylori (H. pylori) eradication success rate of≥ 90%, and higher failure rates in single-resistant strains despite tailored treatment indicate overlooking a mixed infection of a CAM-susceptible and a CAM-resistant H. pylori strain due to a sampling error. Guidelines in each country for H. pylori eradication therapy [2] recommend a success rate of≥ 90%. Therefore, it is important to implement microbial sensitivity tests. The Maastricht V guidelines recommend that clarithromycinbased triple therapy without prior microbial sensitivity tests should be abandoned when the regional CAM resistance rate is> 15%[3]. In recent guidelines, nonbismuth quadruple therapy, sequential or concomitant treatment, or bismuth quadruple therapy is recommended as the first-line therapy in regions where CAM-resistance is> 15%[3, 4]. However, inappropriate use of antibiotics leads to resistance acquisition to H. pylori and microbial sensitivity tests are highly important from the viewpoint of appropriate use of antibiotics. Here, I want to present one concern regarding microbial sensitivity tests and one data regarding CAM-susceptible and a CAM-resistant H. pylori strain coinfection. First, I have a concern about microbial sensitivity tests for H. pylori. Le Thi et al. reported that microbial sensitivity tests are widely available in Europe; however, I believe that they are not readily available worldwide. Culture-based microbial sensitivity tests using epsilometer tests or disk diffusion are time-consuming and limited in facilities where they can be performed. Additionally, the fact that it takes several days to receive the results makes it impossible to start eradication treatment promptly, which is a burden for medical physicians and patients. In Japan, microbial sensitivity test cultures for H. pylori are not covered by public health insurance in some areas. In children, esophagogastroduodenoscopy is used to collect specimens, which is highly invasive and may be technically limiting in facilities where it can be performed. To measure microbial sensitivity tests for H. pylori, molecular detection requires large and expensive dedicated equipment and specialized skills. I fear that the difficulty in conducting microbial sensitivity tests is a major limitation with respect to their conclusions. It is essential to further develop and expand simple and economical methods that can test the microbial sensitivity tests for H. pylori to expand tailored therapies for H. pylori eradication. Second, missed coinfection detection of a CAM-susceptible and a CAM-resistant H. pylori strain led to standard triple-therapy failure, including CAM. However, there is limited information about its existence. In our study, in which 120 third-year junior high school students infected with H. pylori were evaluated for CAM resistance via PCR sequencing using stool, 12 (10%; 12/120) were mixed infected [5](Table 1). Mixed infection rates were similar to those reported by Le Thi et al.[1]. The 12 students with mixed infections were treated with vonoprazan, AMPC, and CAM, and eight students (66.7%; 8/12) reported successful eradication. In this study, the eradication success rate was 94.3%(33/35) in the non CAM-resistant group and 72.9%(35/48) in the CAM-resistant group with vonoprazan, AMPC, and CAM. In our study, CAM-based therapy in mixed infections showed a lower eradication success rate than the non CAM-resistant groups. It was suggested that misjudging mixed …
