Interleukin-8 and granulocyte-macrophage colony-stimulating factor secretion in hepatocellular carcinoma and viral chronic active hepatitis.
Interleukin-8 (IL-8) and granulocyte-macrophage colony-stimulating factor (GM-CSF) are important mediators of inflammation and immune response in human disease. To demonstrate their importance in pathophysiological processes in liver disease, we measured the circulating levels of IL-8 and GM-CSF in patients with hepatocellular carcinoma (HCC) and chronic active hepatitis (CAH). IL-8 and GM-CSF levels in serum samples were determined with highly specific and sensitive enzyme-linked immunosorbent assays. IL-8 levels were more elevated in serum samples of patients with HCC and CAH associated with hepatitis C virus infection than HCC and CAH associated with hepatitis B virus infection. However, in all patients with autoimmune CAH and in some patients with HCC and CAH, GM-CSF levels were elevated over the baseline levels measured in all of the normals, but this difference was not statistically significant for any group. We conclude that IL-8 and GM-CSF are increased in some patients with liver diseases, and as such they may play a significant role in host defense and disease.
