Abstract (original English)
Nonalcoholic fatty liver disease (NAFLD) represents a growing cause of chronic liver injury, especially in western countries, where it is becoming the most frequent indication for liver transplantation. Nonalcoholic fatty liver disease encompasses a spectrum of diseases that from simple steatosis (pure NAFLD) can progress to nonalcoholic steatohepatitis (NASH), cirrhosis and hepatocellular carcinoma. The pathogenesis of NAFLD and the mechanisms behind its progression to NASH have been extensively studied. However, although the processes that determine fat accumulation are mostly clear, the mechanisms associated with the progression of the disease are not fully characterized. In predisposed patients, lipid accumulation can promote lipotoxicity and mitochondrial dysfunction, thus triggering hepatocyte death, inflammation and fibrosis. The specific role of different lipids has been identified and free fatty acids as well as free cholesterol have been identified as toxic species. To make the picture more complex, the pathogenesis of NAFLD involves pathological connections between several organs, including the adipose tissue and the gut, with the liver. The "inflamed" adipose tissue plays a key role in the release of toxic lipids, whereas alterations in the gut-liver axis have been associated with the progression from NAFLD to NASH mediated by dysbiosis, alteration of intestinal bar
What this study does not prove
- • This study does not prove SVF is an approved treatment or a replacement for standard care.
- • This is a narrative review: it collects no new patient data and does not systematically appraise evidence quality.
