Background: Gut microbiota dysregulation is increasingly recognized as a key contributor to the progression of liver cirrhosis and its complications, particularly hepatic encephalopathy. Fecal microbiota transplantation (FMT) has emerged as a novel therapeutic strategy aimed at restoring intestinal microbial homeostasis and modulating systemic inflammation. Methods: This prospective, single-center clinical trial evaluated the short-term safety and efficacy of FMT in patients with alcohol-related liver cirrhosis. Clinical assessment, liver stiffness (via elastography), steatosis (controlled attenuation parameter), inflammatory biomarkers, and extended biochemical panels were analyzed at baseline, one week and one month post-FMT. A control group receiving standard medical therapy was used for comparison. Results: FMT was associated with a significant reduction in hepatic encephalopathy severity (p = 0.014), sustained improvements in liver stiffness (p = 0.027) and decreased steatosis (p = 0.025). At one month, C-reactive protein and neutrophil-to-lymphocyte ratio both declined significantly (p = 0.043), indicating a measurable anti-inflammatory effect. No serious adverse events were recorded. In comparison with controls, FMT recipients showed lower systemic inflammation and improved neuropsychiatric status. Conclusions: FMT demonstrated a favorable safety profile and yielded early clinical and biochemical benefits in patients with cirrhosis. These preliminary findings support the potential utility of microbiota-based interventions in chronic liver disease and warrant validation in larger, multicenter trials.
