Alternation of supragingival microbiome in patients with cirrhosis of different Child-Pugh scores.

Abstract

OBJECTIVES:

The aim of this study was to analyze the differences in the taxonomy and functions of oral microbiome between patients with and without cirrhosis.

MATERIALS AND METHODS:

In this study, V4-16S rDNA amplicon sequencing was used to compare the difference of supragingival microbiome in 42 patients and 12 healthy individuals.

RESULTS:

Overall, 3,223,529 clean reads were generated, with an average of 59,694 ± 1,548 clean reads per sample. A total of 30 phyla, 78 classes, 116 orders, 167 families, 228 genera, and 114 species were detected in the 54 samples. The differences were detected among groups at each taxonomical level. Functional prediction showed that patients with cirrhosis had a significant higher proportion of the genes associated with carbohydrate transport and metabolism, defense mechanisms, infectious diseases, membrane transport, etc. compared with healthy individuals (p < .05).

CONCLUSIONS:

In conclusion, significant differences were observed in compositions and predictive functions of the supragingival microbiome between patients with cirrhosis and that in healthy people. These findings will provide a new insight into the understanding of pathogenesis, diagnosis, prognosis, and therapy of cirrhosis.
