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 .
Effect of a probiotic on liver aminotransferases in nonalcoholic fatty liver disease patients: a double blind randomized clinical trial.
OBJECTIVE The present pilot trial was carried out to evaluate the effects of an acute treatment with a mixture containing 500 million of Lactobacillus bulgaricus and Streptococcus thermophilus per day in patients with non alcoholic fatty liver disease ( NAFLD ) . RESEARCH METHODS A sample of 30 patients with NAFLD ( diagnosed by liver biopsy ) was enrolled and 28 patients were analyzed in a double blind r and omized clinical trial . Patients were r and omized to one of the following treatments during 3 months : group I , treated with one tablet per day with 500 million of Lactobacillus bulgaricus and Streptococcus thermophilus and group II , treated with one placebo tablet ( 120 mg of starch ) . RESULTS In group I , alanine amino transferase ( ALT : 67.7 + /- 25.1 vs. 60.4 + /- 30.4 UI/L ; p < 0.05 ) , aspartate aminotransferase activity ( AST : 41.3 + /- 15.5 vs. 35.6 + /- 10.4 UI/L ; p < 0.05 ) and gammaglutamine transferase levels ( gammaGT : 118.2 + /- 63.1 vs. 107.7 + /- 60.8 UI/L ; p < 0.05 ) decreased . In group II , all liver function parameters remained unchanged ( ALT : 60.7 + /- 32.1 vs. 64.8 + /- 35.5 UI/L ; p < 0.05 ) , aspartate aminotransferase activity ( AST : 31.7 + /- 13.1 vs. 36.4 + /- 13.8 UI/L ; ns ) and gammaglutamine transferase levels ( gammaGT : 82.1 + /- 55.1 vs. 83.6 + /- 65.3 UI/L ; ns ) . Anthropometric parameters and cardiovascular risk factors remained unchanged after treatment in both groups . CONCLUSION A tablet of 500 million of Lactobacillus bulgaricus and Streptococcus thermophilus , with a r and omized clinical design , improved liver aminotransferases levels in patients with NAFLD
