Clinical and Pathological Features, and the Mechanism of Development in Severe Alcoholic Hepatitis, Especially in Comparison with Acute Type Fulminant Hepatitis

Abstract

Among the patients with alcoholic hepatitis, the patients with severe alcoholic hepatitis (SAH) were distinguished by clinical course, laboratory data and histological findings. The aim of this study was to clarify the clinicopathological features, pathological condition and pathogenesis of SAH. Twenty-four SAH patients were compared with 55 patients with acute type fulminant hepatitis (FH) and the other types of alcoholic liver disease. SAH showed a very poor prognosis with a survival rate of 25% and was complicated by multiple organ failure earlier than FH. IgA class lipid A antibody, endotoxin (Et) and tumor necrosis factor-alpha (TNF-alpha) levels in the blood well reflected the pathological condition and severity of SAH. The white blood cell count in the peripheral blood was thought to be the simplest indicator for the prediction of the prognosis of SAH. In conclusion, SAH involves hyper-endotoxemia due to dysfunction of the reticuloendothelial system in the liver, and cytokines including TNF-alpha and neutrophils play an important role in the severity of liver injury.
