Peripheral blood lymphocyte populations in chronic liver disease

Mature T lymphocyte concentrations are reduced, null cell concentrations are increased, and Fc receptor bearing (B and K) lymphocyte concentrations are normal, in the peripheral blood of patients with chronic hepatocellular or cholestatic liver disease. Some null cells can be stimulated by either thymosin or levamisole to form rosettes with sheep erythrocytes. These changes are present in viral, alcohol associated and 'autoimmune' liver disease and are therefore probably secondary phenomena relating to liver damage.
