The liver status was described by the Child-Pugh, MELD & GAHS -scores. In the cirrhosis patients we conducted liver vein catheterisations with measurement of the hepatic venous pressure gradient (HVPG) and at the same time measured blood concentrations of sCD206, sCD163. Short term survival data (84-days) was collected for AH patients and long term Navitoclax nmr (4 years) for AC patients. The Kaplan Meier method was used for survival analysis. Results: The sCD206 concentration was markedly increased in ALD (AH 1.32, AC 0.44, HC 0.20 mg/L; p<0.002). sCD206 increased in a stepwise manner with the CP-score (p<0.001). sCD206 correlated positively with sCD163 in both cirrhosis (p>0.0001, r=0.6) and

AH patients (p>0.0001, r=0.6). In AC, Receiver Operator Characteristics (ROC) analysis showed sCD206 were able to predict portal hypertension Ivacaftor cost (HVPG > 10 mmHg) with an area under the ROC curve of 0.87. In AC, patients with a high level of sCD206 (>0.43 mg/l) had a higher mortality rate than patients with a low level of sCD206 (p=0.02). Conclusion: The soluble mannose receptor sCD206 is highly elevated in alcoholic liver disease, especially in patients with alcoholic hepatitis, and correlates strongly with the macrophage activation marker sCD163. sCD206 predicts portal hypertension and long term mortality in cirrhosis patients but not short term AH mortality.

Vilstrup Background & Aim: Growing clinical and experimental evidence suggests that sterile inflammation contributes to alcoholic liver disease. High-mobility group box-1 (HMGB1) is highly induced during liver injury; yet, a link between this alarmin and alcoholic liver disease has not been established. Thus, the aim of this work was to determine whether HMGB1 contributes to the pathogenesis of alcoholic liver disease. Results: Liver biopsies from patients with alcoholic liver disease showed a robust increase in HMGB1 expression and translocation, which correlated with disease stage, compared to healthy explants. Similar findings were observed in three mouse models of alcoholic liver disease. Using primary cell culture, we validated the ability of hepatocytes from ethanol-fed mice or of hepatocytes treated with ethanol to secrete a large amount of HMGB1. Secretion was time- and dose-dependent under etha-nol treatment and responsive to prooxidants and antioxidants.
