Objective. Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease in the world. The pathogenesis of NAFLD is complex and multifactorial. Clinical studies have shown that alterations in the gut microbiota play a key role in NAFLD. The purpose of this study was to analyze the effect of probiotic supplementation on the treatment of NAFLD patients based on various indicators. Methods. We conducted a meta-analysis investigating the relationship between NAFLD and probiotic supplementation. Embase, PubMed, and Web of Science databases were searched by computer, and then, eligible studies were identified. Finally, a total of high-quality randomized controlled trials were selected involving 1403 participants. Meta-analysis was performed using the RevMan 5.3 software which was systematically searched for works published through Dec. 1, 2021, in the present study. Results. The meta-analysis results showed that the probiotics supplementation improved hepatocyte injury and significantly reduced the level of ALT ( P = 0.00001 ), AST ( P = 0.0009 ), GGT ( P = 0.04 ), TG ( P = 0.01 ), LDL-C ( P = 0.0005 ), HDL-C ( P = 0.0002 ), insulin ( P = 0.003 ), IR ( P = 0.03 ), BMI ( P = 0.03 ), TNF-α ( P = 0.03 ), and CRP ( P = 0.02 ), respectively, in NAFLD patients. Conclusion. The present study suggests that probiotics therapy may improve liver enzyme levels, regulated lipid metabolism, reduced insulin resistance, and improved inflammation in NAFLD patients. It supports the potential role of probiotics supplementation in the treatment of NAFLD.
