Indocyanine green clearance was measured in 23 symptomatic patients with primary biliary cirrhosis who were followed up for 6 months. Ten patients either died (n = 4) from their primary biliary cirrhosis or underwent liver transplantation (n = 6) during the follow-up period. Indocyanine green clearance and other liver function test results were compared between the survivors (n = 13) and those who had died or undergone transplantation (n = 10). Indocyanine green clearance, bilirubin, bile acids, albumin, and prothrombin ratio differed significantly between the two groups, whereas age, alkaline phosphatase, globulin, and aspartate aminotransferase did not. Indocyanine green clearance gave better discrimination between the two groups than the other liver function tests, including bilirubin. There was a close correlation between indocyanine green clearance and bilirubin in patients who died or were transplanted. Further studies are necessary to define whether indocyanine green clearance is clinically useful in selecting patients for transplantation and in the timing of intervention.
