Background: Gut dysbiosis is common in cirrhosis.

Aim: To study the influence of gut dysbiosis on prognosis in cirrhosis.

Methods: The case-control study included 48 in-patients with cirrhosis and 21 healthy controls. Stool microbiome was assessed using 16S ribosomal ribonucleic acid gene sequencing. We used modified dysbiosis ratio (MDR): [ (%) + (%)]/[ (%) + (%)]. Patients with MDR more the median made up the group with severe dysbiosis, others did the group with non-severe dysbiosis. The follow-up period was 4 years.

Results: The mortality rate of patients with severe dysbiosis was significantly higher than that of patients with non-severe dysbiosis (54.2% 12.5%; = 0.001). The presence of severe dysbiosis was independent risk factors for death [hazard ratio = 8.6 × (1.9-38.0); = 0.005]. The abundance of ( = 0.002), ( = 0.002), and ( = 0.025) was increased and the abundance of ( = 0.025) and ( = 0.045) was decreased in the deceased patients compared with the survivors. The deceased patients had a higher MDR value than the survivors [0.131 × (0.069-0.234) 0.034 × (0.009-0.096); = 0.004]. If we applied an MDR value of 0.14 as the cutoff point, then it predicted patient death within the next year with a sensitivity of 71.4% and a specificity of 82.9% [area under the curve = 0.767 × (0.559-0.974)]. MDR was higher in patients with cirrhosis than in health controls [0.064 × (0.017-0.131) 0.005 × (0.002-0.007); < 0.001], and in patients with decompensated cirrhosis than in patients with compensated cirrhosis [0.106 × (0.023-0.211) 0.033 × (0.012-0.074); = 0.031]. MDR correlated negatively with prothrombin ( = -0.295; = 0.042), cholinesterase ( = -0.466; = 0.014) and serum albumin ( = -0.449; = 0.001) level and positively with Child-Turcotte-Pugh scale value ( = 0.360; = 0.012).

Conclusion: Gut dysbiosis is associated with a poorer long-term prognosis in cirrhosis.
