Characteristics of intestinal microflora in patients with vitiligo / 中华医学美学美容杂志

ABSTRACT

Objective:To study the characteristics of intestinal microflora in patients with vitiligo, and to analyze the relationship between the changes of intestinal microflora and the incidence of vitiligo, so as to provide new ideas for clinical treatment.Methods:Fecal specimens from 30 patients with vitiligo and 30 healthy adults were collected and analyzed qualitatively by Roche/45 high-throughput sequencing platform. At the same time, macrogenomics was used to analyze the feces of 5 patients with vitiligo and 5 healthy adults to identify the potential regulatory pathways.Results:The bacterial species in the feces of patients with vitiligo were similar to those of healthy people, but the intestinal microbial diversity of patients with vitiligo was significantly reduced ( P<0.01); the abundance of Proteus and Clostridium was significantly reduced at phylum level; at genus level, 7 of them were Bacteroides, Escherichia coli Shigella, Rochella, Bacillus anthracis, Clostridium clostridium, Jordani bacteria. The abundance of RF9 and Prunella-7 decreased significantly ( P<0.01), while the abundance of 4 genera (Rumen Coccus-1, Rumen Coccus UCG, Trichomonas and Streptococcus) increased significantly ( P<0.01). The expression of Streptococcus and Phase Anthraceae in vitiligo patients was significantly different the former increased by 10.8 times, the latter decreased by 6.517 times, and an intestinal microorganism based on 11 vitiligo-related genera was constructed. The random forest model of bacterial flora showed that AUC of the discriminant model was 0.89 in ROC, and macrogenomic analysis showed that the disorders of vitiligo-related bacterial flora were mainly related to immune-related pathways (such as WNT pathway, Notch pathway), energy metabolism, mitochondrial function and amino acid metabolism (such as phenylalanine metabolism). Conclusions:The diversity of bacterial community in intestinal microecological environment of vitiligo patients is significantly different from those in normal people. The imbalance of bacterial community may be involved in the pathogenesis and development of vitiligo. Supplementation of probiotics may be beneficial to the treatment of vitiligo.
