ABSTRACT
Objective:To observe the results of 16S rDNA high-throughput sequencing analysis of intestinal flora in patients with depression before and after antidepressant treatment.Methods:94 patients with major depression treated in the First Hospital of Shanxi Medical University from January 2020 to December 2020 were selected as the research objects. All patients were treated with paroxetine hydrochloride for 12 weeks. Fecal samples were collected before and after treatment. The patients were divided into effective group and ineffective group according to the treatment effect. 16S rDNA high-throughput sequencing was used to detect the changes of flora before and after treatment.Results:There was significant difference in age and gender between the two groups (all P<0.05). There was no significant difference in α diversity index such as Chao1, PD and Shannon index between effective group and ineffective group before and after treatment (all P>0.05). β diversity analysis showed that there was a graphical difference between the effective group and the ineffective group at baseline, but it did not show statistical significance after adjusting for age and gender (Adonis, P=0.078). Compared with the ineffective group, the effective group had fecal bacilli enrichment at baseline. β-diversity analysis showed that there was no clear pattern of microbiota changes in the effective group ( P=0.142) and ineffective group ( P=0.127) from baseline to post-treatment. After treatment, the abundance of Roche bacteria in the effective group increased significantly ( P=0.013, Cohen′s d=1.90), while the abundance of Flavonifractor decreased significantly ( P=0.01, Cohen′s=5.84). Before and after treatment, the samples of the ineffective group did not identify the genus with diversity through DESeq2. The logarithm ratio of the top ranked genera (top 12%) to the bottom ranked genera (bottom 12%) in the ineffective group increased significantly ( P=0.027, Cohen′s=1.1). Conclusions:The baseline fecal microbiota status may have an impact on the treatment outcome of depression, and improving the intestinal microbiota status may contribute to the remission of depression.
