Assessment

Primary outcomes

Analysis of intestinal bacterial flora

Regarding intestinal flora, the base sequence (read data) of 16S rRNA gene derived from intestinal bacteria obtained by analysis with NGS is grouped (OTU classification) according to the similarity (96 to 97%) , A relative proportion of the microflora composition of each specimen is calculated by performing phylogenetic identification for each OTU. A comparison is made between the groups on this microflora configuration. As a comparison method, the similarity of each flora is examined by comparing beta-diversity (UniFrac analysis and HeatMap cluster analysis) and alfa-diversity comparison (OTU number, chao 1, PD whole tree, Shannon index). In addition, we compare the ratio of the bacterial group constituting the flora and the average number / median value.

Key secondary outcomes

Compare the presence and absence of side reactions and the extent of side reactions between the groups in the group treated with H. pylori eradication therapist combined with or without biofermin R combination.

Interventions/Control_1

H. pylori infected individuals are randomly divided into two groups, one treated with H. pylori by disinfectant plus Biofermin R (biofermin R combination group), while the other one is H. pylori excluded only by bacteriocide treatment (biofermin R non-combined group). In both groups, each stool is collected before sterilization treatment, from day 7 to day 8 of eradication treatment, and before decontamination judgment, flora analysis is performed using next generation sequencer (NGS).

Interventions/Control_2

In both groups, the appearance and alleviation effect of side reactions associated with eradication treatment are judged.
