Personalized Long-term Human Albumin Treatment in Patients With Decompensated Cirrhosis and Ascites

The goal of this clinical biomarker validation trial is to test the effect of a predictive biomarker panel to human albumin infusions in patients with liver cirrhosis and ascites. The main questions it aims to answer are: * If the predictive biomarker panel can identify patients who are likely to benefit from regular human albumin infusions * If the predictive biomarker panel can lower the number-needed-to-treat of regular human albumin infusions in patients with liver cirrhosis and ascites The predictive biomarker panel will stratify patients into either a high- or low-expected effect of human albumin infusions. Hereafter are participants randomized into treatment arms. Participants in the active treatment arm will receive regular human albumin infusions during a course of 6 months. Infusions will occur every 10th day for the duration of the study. Researchers will compare 20% human albumin infusions with regular 0.9% sodium chloride to identify the effects on the number of liver-related events.
