Background & Aims:
Acute-on-chronic liver failure (ACLF) is characterized by high short-term mortality and systemic inflammation (SI). Recently, different cardiodynamic states were shown as independent predictors of outcomes in cirrhosis. The relationship between cardiodynamic states, SI and portal hypertension and their impact on ACLF development have not been fully studied. The aim of the present study was therefore to evaluate the interplay of cardiodynamic state, fatal ACLF development and SI in liver cirrhosis.
Approach & Results:
At inclusion, haemodynamic measures including the cardiac index (CI) and hepatic venous pressure gradient (HVPG) of 208 cirrhotic patients were measured. Patients were followed prospectively for fatal ACLF (primary endpoint). SI was assessed measuring the levels of proinflammatory interleukins (ILs) 6 and 8 and IL-33 receptor – soluble ST2.
Patients were divided according to CI (< 3.2; 3.2 – 4.2; > 4.2 L/min/m2) in hypo- (n = 84), normo- (n = 69) and hyperdynamic group (n = 55). After a median follow up of 3 years, the highest risk of fatal ACLF was seen in hyperdynamic (35%) and hypodynamic patients (25%) compared to normodynamic (14%) (p = 0.011). Hyperdynamic state showed highest rate of SI. The detectable level of IL-6 was an independent predictor of fatal ACLF development.
Conclusions:
Cirrhotic patients with hyperdynamic and hypodynamic circulation, have a higher risk of fatal ACLF. Hyperdynamic state is strongly associated with elevated markers of systemic inflammation, which independently predict fatal ACLF development.
