Cytokines in Detoxified Patients with Chronic Alcoholism Without Liver Disease: Increased Monocytic Cytokine Production

Background: The aim of the present study was to examine the production of interferon-gamma, tumor necrosis factor-alpha (TNF-alpha), granulocyte-macrophage colony stimulating factor (GM-CSF), interleukin-6 (IL-6), IL-10, IL-4, IL-5, IL-1 receptor antagonist (IL-1RA), and prostaglandin E2 in relation to the number of leukocytes in the blood of detoxified, chronic alcoholic patients without apparent liver disease (AWLD).

Methods: Phytohemagglutinin + lipopolysaccharide-induced production of the above variables as well as the number of white blood cells and differentials were determined in detoxified AWLD patients and normal volunteers.

Results: Detoxified AWLD patients have a significantly higher production of IL-6, IL-10, TNF-alpha, GM-CSF, and IL-1RA and significantly increased numbers of leukocytes and neutrophils compared to normal volunteers.

Conclusions: Detoxified AWLD patients show an increased production of proinflammatory cytokines, i.e., IL-6, TNF-alpha, and GM-CSF, as well as negative immunoregulatory proteins, such as IL-10 and IL-1RA.
