Proton pump inhibitors (PPIs) are widely used to treat gastro-esophageal reflux and prevent gastric ulcers, and have been considered as low risk. However, recent studies have identified possible associations between PPI use and gut microbiota, suggesting that PPIs use increases the risk of enteric infections, including Clostridium difficile infection. To investigate gut microbiota in Japanese PPIs users, we conducted 16S metagenomics analysis of fecal samples collected from PPI users and healthy adults. In total, 36 PPI users and 36 PPI non-users (as control subjects) matched by age and sex were recruited and fecal samples were obtained to analyze the gut microbiome using 16S rRNA gene sequencing. There were significant differences in the microbial structure between PPI non-users and PPI users. In contrast, the analysis of α-diversity revealed no significant differences between PPI non-users and PPI users. When comparing in genus level between these two groups, the genera Streptococcus was significantly abundant and the genera Faecalibacterium was significantly decreased in PPI users. Our findings indicate a probable association between PPI use and the alternation of microbiota. These alterations might provide a mechanism by which PPIs predispose enteric infection such as Clostridium difficile infection.

The eradication rate of Helicobacter pylori (H. pylori) with proton pump inhibitors, amoxicillin, and clarithromycin has reportedly decreased. Some studies have found probiotics to be useful in eradicating H. pylori, but these effects have not been sufficiently investigated. We aimed to elucidate the role of probiotics in eradicating H. pylori infection. Patients in our hospital with H. pylori infection that received standard treatment from January 2015 to December 2016 were retrospectively evaluated (n = 468). They were divided into three groups based on their treatment regime, being either proton pump inhibitors, amoxicillin, or clarithromycin (PPI group), vonoprazan, amoxicillin, or clarithromycin (VPZ group), and proton pump inhibitors, amoxicillin, or clarithromycin/probiotics (Miya-BM®) (PPI + MBM group). We retrospectively evaluated the H. pylori eradication rate and reported side effects. According to intention-to-treat analyses, the eradication rate of H. pylori was significantly higher in the PPI + MBM group (87.1%) than in the PPI group (70.1%). There was no difference in side effects between any of the three groups. In conclusion, Miya-BM® may have an additive effect when included with eradication therapies for H. pylori.

We present the case of a patient who was referred to our hospital after she reported having passed a long, whitish object per rectum. Accordingly, capsule endoscopy was performed using the PillCam® SB video capsule. A tapeworm of the species Diphyllobothrium nihonkaiense was detected; it appeared to be freely floating and unfolded in the jejunum and sometimes tangled or irregularly folded in the ileum. The stretching of the strobila by strong peristalsis in the ileum may have resulted in the separation of the caudal portion of the strobila, which descended into the colon and was eventually passed per rectum.
