Faecal bacterial microbiota in patients with cirrhosis and the effect of lactulose administration.

ABSTRACT:

Background

Gut microbiota may be altered in patients with cirrhosis, and may further change after administration of lactulose. We studied the composition of gut microbiota in patients with cirrhosis and assessed the effect on it of lactulose administration.

Methods

Stool specimens were collected from 35 patients with cirrhosis (male 26; median [range] age: 42 [29-65] years) and 18 healthy controls (male 14; 44.5 [24-67] years); 21 patients provided another specimen after lactulose administration for 55 [42-77] days. For each, a DNA library of V3 region of bacterial 16S ribosomal RNA was subjected to paired-end Illumina sequencing. Inter-specimen relationship was studied using principal co-ordinate analysis. Abundances of various bacterial taxa, and indices of alpha and beta
