Fecal microbiota transplantation (FMT) is a method to directly change the recipient's gut microbiota to normalize the composition and gain a therapeutic benefit. The history of FMT has been traced back to the 4th century and has been highly regarded since 2013, when the United States Food and Drug Administration approved FMT for treating recurrent and refractory Clostridium difficile infection. Since then, the range of FMT applications extended rapidly and broadly not only in gastrointestinal disorders, but also in extra-gastrointestinal diseases. Donor selection with questionnaire, interview, blood tests, and stool examinations should be strictly performed before FMT to reduce and prevent occurrence of any adverse events. Step-by-step cautious fecal and recipient preparation along with adequately choosing delivery methods based on individual clinical situations are key points of the FMT process. Although current evidence deems FMT as a generally safe therapeutic method with few adverse effects, the long-term outcomes of FMT have not been completely elucidated. Therefore, establishing periodicity and length of regular follow-up after FMT to monitor the clinical efficacy and long-term adverse events are other essential issues. In the future, we will look forward to personalized FMT for different patients and conditions according to varied hosts and diseases.

Background & Aims-Sequential therapy with a proton pump inhibitor (PPI) and amoxicillin followed by a PPI, clarithromycin, and an imidazole agent reportedly have a better rate of curing Helicobacter pylori infection than PPI, amoxicillin, clarithromycin triple therapy. The concomitant administration of these 4 drugs (concomitant therapy) is also an effective treatment strategy. We compared the efficacies of sequential and concomitant therapy and analyzed the effects of antibiotic resistance in patients with H. pylori infection.

Background Ten day sequential therapy with a proton pump inhibitor (PPI) and amoxicillin followed by a PPI, clarithromycin, and an imidazole typically achieves Helicobacter pylori eradication rates of 90 to 94% (Grade B success). Aims We tested whether prolonging treatment and continuing amoxicillin throughout the 14-day treatment period would produce a ≥95% result. Methods This was a multi-center pilot study in which H pylori infected patients received a 14-day sequential-concomitant hybrid therapy (esomeprazole and amoxicillin for 7 days followed by esomeprazole, amoxicillin clarithromycin, and metronidazole for 7 days). H pylori status was examined 8 weeks after therapy. Success was defined as achieving ≥95% eradication by per-protocol analysis. Results 117 subjects received hybrid therapy. The eradication rate was 99.1% (95% CI, 97.3%–100.0%) by per-protocol analysis and 97.4% by intention-to-treat analysis (95% CI, 94.5–100.0%). Adverse events were seen in 14.5%; drug compliance was 94.9%. Conclusions 14-day hybrid sequential-concomitant therapy achieved greater than 95% H. pylori eradication (Grade A result). Further studies are needed (i) in regions with different patterns and frequencies of resistance to confirm these findings and (ii) to examine whether Grade A success is maintained with hybrid therapy shorter than 14 days.
