Conclusion We present clear evidence for the benefit of probiotics and synbiotics supplementation  for liver steatosis , liver enzymes , lipid profiles and liver stiffness in patients with NAFLD
Background and Aim Extensive epidemiological evidence suggests that nonalcoholic fatty liver disease ( NAFLD ) is the primary chronic liver disease worldwide .
However , some studies have showed conflicting results on the effects of probiotics and synbiotics supplementation .
Therefore , we conducted a systematic review and meta- analysis to investigate the effectiveness of the supplementation in subjects with NAFLD .
[Efficacy of probiotics on the treatment of non-alcoholic fatty liver disease].
Objective : To study the clinical effect of probiotics in the treatment of non-alcoholic fatty liver disease ( NAFLD ) . Methods : A total of 200 patients with NAFLD were r and omly divided into 4 groups : control group ( routine treatment group ) and combined treatment group A , B and C. Each group had equal patients . The control group received orally polyene phosphatidylcholine capsules ; whereas combined group A , B and C were given orally the live " combined Bifidobacterium Lactobacillus and Enterococcus powder " , " two live combined Bacillus subtilis and Enterococcus " , and the both probiotics respectively . The duration of treatment was 1 month . Laboratory parameters were evaluated before treatment and thirtieth day after treatment , including cholesterol ( TC ) , triglyceride ( TG ) , high density lipoprotein cholesterol ( HDL-C ) , low density lipoprotein cholesterol(LDL-C ) , alanine aminotransferase(ALT ) , aspartate aminotransferase ( AST ) , fasting blood glucose ( FPG ) , serum high molecular weight adiponectin ( HMW-APN ) and serum TNFα . Meanwhile the faece sample was collected for routine test and bacterial culture . Liver ultrasound scan was done in all patients . Results : In terms of blood lipids and blood glucose , each group improved after treatment with significant differences ( P<0.05 ) except for HDL-C. As for liver function , serum ALT and AST decreased after treatment in each group ; especially in combined group C which were lower than those of control group [ ( 33.7±7.6 ) U/L vs. ( 45.0±8.5 ) U/L ; ( 22.0±1.6 ) U/L vs. ( 29.4±3.7 ) U/L ; P<0.05 ] . TNFα levels decreased after treatment in each group , in addition the values in combined group C was significantly lower than that of control group[(0.51±0.27 ) µg/L vs. ( 0.82±0.28 ) µg/L , P<0.05 ] . Serum HMW-APN increased after treatment in each group , and the HMW-APN in combined C group was significantly higher than that of control group[(9.28±3.72 ) µg/L vs. (7.87±3.96)µg/L , P<0.05 ] . ( 5 ) After treatment , all groups showed improvement of fatty liver by ultrasound , but the difference between groups was not statistically significant . ( 6 ) Compared with before treatment , fecal flora in combined groups was all reduced ( P<0.01 ) , but it was comparable before and after treatment in control group . Conclusions : Probiotics improve intestinal microecological system in NAFLD patients via inhibiting TNFα and enhancing adiponectin , possibly result ing in regulating blood glucose , lipid metabolism , and protecting liver injury from NAFLD
