Impact of a Multi-strain Probiotic Supplementation With Lifestyle Modification on Liver Steatosis, Fibrosis, and Metabolic Health in Patients With Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD)

Обзор

Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is the new clinical term introduced in 2023 to redefine what was formerly known as Non-Alcoholic Fatty Liver Disease (NAFLD). It is defined as fatty liver confirmed by imaging or biopsy, accompanied by at least one cardiometabolic risk factor (e.g., hyperglycemia, dyslipidemia, hypertension, or obesity). Its pathological progression ranges from simple steatosis to steatohepatitis, primarily driven by excessive energy intake, hepatic lipid accumulation, and insulin resistance. MASLD is currently the most prevalent chronic liver disease globally, with a prevalence rate of approximately 30-40%. However, there is no satisfactory pharmacological treatment, leaving lifestyle modification as the primary therapeutic approach. Many patients struggle to effectively adjust their habits, leading to persistent hepatic inflammation and damage, which may eventually progress to end-stage diseases such as cirrhosis and hepatocellular carcinoma. In many developed countries, MASLD has become the leading indication for liver transplantation, imposing a heavy burden on healthcare systems. Gut dysbiosis is closely linked to MASLD. An imbalance in the gut microbiota disrupts the gut-liver axis, leading to impaired intestinal mucosal barrier function. This allows bacterial components to enter the circulation, further triggering hepatic inflammation and abnormal lipid metabolism. Consequently, modulating the gut microbiota is considered a potential therapeutic strategy. Over the past decade, probiotics, prebiotics, and synbiotics have been extensively studied as non-pharmacological treatments for NAFLD. Multiple studies indicate that these products can reduce liver enzymes (AST, ALT), insulin resistance (HOMA-IR), and inflammatory markers (hs-CRP, TNF-α). The most effective combinations typically involve Lactobacillus, Bifidobacterium, and Streptococcus, with a recommended duration of approximately 12 weeks. However, the impact of these products on liver fibrosis, hepatic fat accumulation, and cardiometabolic risk factors remains inconclusive. The probiotic product to be tested consists of Lactobacillus salivarius AP-32, Lactobacillus rhamnosus bv-77, Bifidobacterium animalis CP-9, and Lactobacillus reuteri GL-104. This formulation complies with food safety regulations. In clinical studies, it had been proven as an effective adjuvant method that increased beneficial gut bacteria such as Akkermansia muciniphila and improved the control of blood glucose, lipids, and inflammatory markers. Study Objectives This study aims to investigate the efficacy of this probiotic product as an adjuvant therapy alongside lifestyle modifications in adult patients with MASLD. We will evaluate its impact on: 1. The degree of liver fibrosis and steatosis 2. Cardiometabolic risk factors (BMI, waist circumference, blood lipids, and blood glucose). 3. Inflammatory markers. 4. Gut microbiota composition.
