Blood group lewis phenotype on erythrocytes and in saliva in alcoholic pancreatitis and chronic liver disease.

The distributions of ABO, rhesus, and Lewis blood group antigens were studied in patients with alcoholic cirrhosis, alcoholic pancreatitis, chronic active hepatitis, and primary biliary cirrhosis. There were no differences in frequencies of ABO and rhesus blood group antigens between the groups or in comparison with a control group of blood donors. Lewis phenotype Le (a- b-), however, was more common on erythrocytes than in saliva in patients with alcoholic cirrhosis, alcoholic pancreatitis, and severe renal disease but equally common in saliva and on red blood cells in patients with non-alcoholic liver disease. It is suggested that Lewis typing should be performed on saliva because blood typing may give misleading results in some patients.
