Abstract:

Objective To investigate the correlation of the kinds of gut common bacteria and serum inflammatory cytokines [tumor necrosis factor alpha(TNF-α),interleukin(IL)-12,IL-6,IL-10,IL-1β and IL-23] in chronic hepatic encephalopathy(HE) patients,and to evaluate the roles of intestinal microecology and serum inflammatory cytokines in chronic HE. Methods Among chronic hepatitis B liver cirrhosis patients with decompensation,120 cases with HE were enrolled as HE group,and 100 cases without HE were enrolled as control group. Liver function indices [albumin(Alb),alanine aminotransferase(ALT),aspartate aminotransferase(AST),total bilirubin(TB) and prothrombin time(PT)] and the Child classification of liver function were recorded. A total of 12 gut common bacteria were determined by fluorescence quantitative polymerase chain reaction(PCR),and serum levels of 6 inflammatory cytokines were determined by enzyme-linked immunosorbent assay(ELISA). Results Alb,ALT,AST,TB and the Child classification of liver function in HE group were higher than that in control group(P<0.05),and there was no statistical significance for PT between the 2 groups(P>0.05). Compared with control group,gut common bacteria with increased proliferation in HE group included pathogenic Escherichia coli,Pseudomonadaceae,Enterococcus,Prevotella,Staphylococcus,Fusobacterium and Candida albicansP<0.05),while gut common bacteria with decreased included Bifidobacterium,Lactobacillus and RuminococcusP<0.05). Serum TNF-α,IL-12,IL-6,IL-10,IL-1β and IL-23 levels in HE group were higher than those in control group(P<0.001). The correlations of gut common bacteria with liver function indices and with serum inflammatory cytokines in HE group were higher than those in control group. Conclusions Gut dysbacteriosis in intestinal microecology might collaboratively contribute to the development mechanism of chronic HE,through regulating the production and secretion of a variety of inflammatory cytokines.
