Abstract
Background-aim
Non-alcoholic fatty liver disease (NAFLD1) is the most frequent chronic liver disorder worldwide. Currently, no pharmacological treatment has been approved for NAFLD. Probiotics have been suggested as a potential therapy for NAFLD. The aim of this systematic review and meta-analysis was to assess the impact of probiotic intake on liver tests, lipids, glycemic parameters and inflammatory markers in NAFLD patients.
Methods
We searched electronic databases using related terms. Meta-analysis was performed using random-effects models. Clinical outcomes were presented as standard mean difference (SMD2) with a 95 % confidence interval (CI3). Publication bias and heterogeneity were evaluated in eligible studies.
Results
Fifteen randomized clinical trials comprising 899 participants were included in our meta-analysis. Probiotic supplementation improved alanine transaminase [SMD -0.796; 95 % CI (−1.419, −0.172); p = 0.012], Homeostatic Model Assessment for Insulin Resistance (HOMA-IR4) [SMD -0.596; 95 % CI (−1.071, −0.121); p = 0.01] and insulin levels [SMD -1.10; 95 % CI (−2.121, −0.087); p = 0.03]. No significant effects were observed on fasting glucose, hemoglobin A1c, aspartate transaminase, lipid profile, interleukin-6 and tumor necrosis factor-α.
Conclusions
Probiotic intake may improve insulin sensitivity and alanine transaminase in NAFLD patients.
期刊介绍：
Journal of Diabetes and Its Complications (JDC) is a journal for health care practitioners and researchers, that publishes original research about the pathogenesis, diagnosis and management of diabetes mellitus and its complications. JDC also publishes articles on physiological and molecular aspects of glucose homeostasis.
The primary purpose of JDC is to act as a source of information usable by diabetes practitioners and researchers to increase their knowledge about mechanisms of diabetes and complications development, and promote better management of people with diabetes who are at risk for those complications.
Manuscripts submitted to JDC can report any aspect of basic, translational or clinical research as well as epidemiology. Topics can range broadly from early prediabetes to late-stage complicated diabetes. Topics relevant to basic/translational reports include pancreatic islet dysfunction and insulin resistance, altered adipose tissue function in diabetes, altered neuronal control of glucose homeostasis and mechanisms of drug action. Topics relevant to diabetic complications include diabetic retinopathy, neuropathy and nephropathy; peripheral vascular disease and coronary heart disease; gastrointestinal disorders, renal failure and impotence; and hypertension and hyperlipidemia.
