Objective:
The CC chemokines monocyte chemoattractant protein-1 (MCP-1) and macrophage inflammatory protein-3 alpha (MIP3-alpha) may be involved in the pathogenesis of acute liver failure (ALF) and acute-on-chronic liver failure (ACLF). In ALF and ACLF, the molecular adsorbent recirculating system (MARS) has been used to support liver function. Enhancement of MCP-1, as seen in other extracorporeal support systems such as haemodialysis, might thus have mitigated the beneficial effects of the MARS system in acute hepatic failure.
Material And Methods:
Serum concentrations of MCP-1 and MIP3-alpha were measured in 10 patients with ALF or ACLF treated with MARS. Thirteen patients suffering from chronic hepatic failure (CHF) and 15 healthy individuals served as controls.
Results:
Baseline MCP-1 serum concentrations were significantly increased in ALF and ACLF patients as compared to patients with CHF (p=0.0027 and p=0.0046, respectively) and controls (p=0.0006 and p=0.0012, respectively). MIP3-alpha serum concentrations were also significantly enhanced in the ALF and ACLF groups as compared with those in CHF patients (p=0.0002 and p=0.0003, respectively) and controls (p<0.0001 and p<0.0001, respectively). Moreover, MIP3-alpha levels were significantly increased in CHF patients as compared to controls (p=0.0002). MCP-1 and MIP3-alpha concentrations did not change significantly during MARS treatment in ALF and ACLF patients.
Conclusions:
The CC chemokines MCP-1 and MIP3-alpha are increased in ALF and ACLF patients. MARS had no effect on MCP-1 and MIP3-alpha serum concentrations in patients with ALF and ACLF, and yielded no evidence of any harmful effects of the increase of these potentially hepatocidal chemokines.
