Alcoholic Liver Disease: Pathogenesis and Current Management

The 'Alcohol Accelerates Hepatic Lipogenesis' section reports that ethanol consumption increases lipolysis in adipose tissue and that the released free fatty acids are taken up by the liver. It does not identify acetaldehyde in particular as the cause of that lipolysis; the section on acetaldehyde instead discusses impaired fatty-acid oxidation. (LLM, conf=0.88)

The Abstract says steatosis can progress to steatohepatitis, and Modifiers of ALD Risk links long-term alcohol intake to more severe disease, including steatohepatitis. Spectrum of ALD describes ballooning hepatocytes and neutrophilic infiltration. The paper does not establish that heavy drinking accelerates the rate of transition from fatty liver to hepatitis, and it does not explicitly describe hepatitis as occurring with or without fibrosis. (LLM, conf=0.83)

The “Mechanisms Involved in Alcoholic Hepatitis” section says LPS activates Kupffer cells, promoting free-radical formation and chemokine release that attracts circulating immune cells. It also identifies Kupffer cells as a source of ROS and describes recruitment of macrophages and neutrophils. It does not say acetaldehyde itself activates Kupffer cells—only that acetaldehyde-containing adducts promote their inflammatory response—or establish the claimed origins of the recruited neutrophils and monocytes. (LLM, conf=0.86)

The “Mechanisms Involved in Fibrosis/Cirrhosis” section says HSCs activate after hepatic injury and become the principal source of extracellular-matrix deposition in fibrosis. The “Spectrum of ALD” section likewise identifies activated HSCs as the principal source of excess matrix proteins. The copy does not specifically establish this in patients with alcoholic steatohepatitis or name collagen and fibronectin as examples. (LLM, conf=0.85)
