Role of Bacterial Infection in the Development of Acute Liver Failure in Patients with Decompensated Alcoholic Liver Cirrhosis.

We examined 74 patients with acute decompensation of alcoholic liver cirrhosis: 34 (45.9%) with bacterial infection (group 1) and 40 (54.1%) without bacterial infection (group 2). The degree and index of acute-on-chronic liver failure (ACLF) were determined using an on-line CLIF-C ACLF Calculator and the levels of cytokeratin-18 fragments, TNFα, IL-1β, IL-4, IL-6, and IL-8. In group 1, AST, cytokeratin-18, TNFα, IL-1β, IL-6, degree and score of ACLF were significantly higher than in group 2. ACLF developed in 18 (52.9%) patients in group 1 and in 11 (27.5%) (p<0.05) patients in group 2. Within 1 month, 10 (29.4%) patients of group 1 and 2 (5%) patients of group 2 died (p<0.05). Patients with bacterial infection showed a more severe course of alcoholic liver cirrhosis and ACLF than those without bacterial infection.
