| خلاصه مقاله | Background: Fatty liver disease (FLD) is characterized by the accumulation of fat in the liver, often leading to inflammation and oxidative stress, which contributes to disease progression. Saffron extract, derived from Crocus sativus, is known for its potent antioxidant properties. This systematic review aims to evaluate the effect of saffron extract on oxidative stress markers in patients with fatty liver disease.
Methods: A comprehensive search was conducted across PubMed, Scopus, and Web of Science for studies published between 2000 and 2024. Studies included were randomized controlled trials, clinical trials, and cohort studies that assessed the impact of saffron extract on oxidative stress markers (e.g., malondialdehyde, glutathione, superoxide dismutase) in patients with fatty liver disease. Inclusion criteria were studies with appropriate control groups and baseline measures of oxidative stress.
Results: A total of 12 studies met the inclusion criteria. Analysis of pooled data demonstrated that saffron extract supplementation significantly reduced oxidative stress markers in patients with fatty liver disease. Specifically, saffron extract led to a significant reduction in malondialdehyde (MDA), a marker of lipid peroxidation, and an increase in antioxidant enzymes such as superoxide dismutase (SOD) and glutathione peroxidase (GPx). These changes were associated with improvements in liver function indicators, including alanine aminotransferase (ALT) and aspartate aminotransferase (AST), suggesting a potential protective effect against liver damage. The doses of saffron extract used in the studies ranged from 20 mg to 200 mg per day, with the most significant effects observed at higher doses and longer intervention periods (≥8 weeks).
Conclusion: Saffron extract appears to have a beneficial effect on reducing oxidative stress markers in patients with fatty liver disease, potentially offering a therapeutic option for mitigating liver damage associated with this condition. Further large-scale, long-term studies are needed to confirm these findings and determine the optimal dosage and duration of saffron extract supplementation for managing oxidative stress in fatty liver disease. |
