High interleukin-6 serum levels and increased production by leucocytes in alcoholic liver cirrhosis. Correlation with IgA serum levels and lymphokines production.
Hypergammaglobulinaemia and enhanced serum IgA levels are common in alcoholic liver cirrhosis. Interleukin-6 (IL-6), which is identical to B cell differentiation factor BSF2 and is implicated in various autoimmune diseases, has been studied in patients with alcoholic liver cirrhosis. Increased serum levels and spontaneous or induced production of IL-6 by peripheral blood monoclonal cells have been found. IL-6 production correlates closely with IgA serum levels and negatively with impaired interleukin-2 and interferon gamma production. This abnormality could be related to overproduction of immunoglobulins and immune disturbances observed in this disease.
