In the group of AIH patients, we observed an association between the serum concentration of MCP-1 and alkaline phosphatase levels—R = 0.25, p = 0.030, and also noted a weak correlation between the serum concentration of MCP-1 and liver fibrosis—R = 0.29, p = 0.02. The gene discussed is CCL2; the disease is Hepatic fibrosis.
