Eight cases of liver disease associated with alpha-1-antitrypsin deficiency are described. Six of the cases, including the only childhood case, showed no evidence of lung disease. An occult but variable clinical course is defined in this disorder. A spectrum in the severity of tissue change was noted, and in some instances, extensive liver disease was correlated with relatively minor derangement in liver function. While this form of liver disease is uncommon, it should be included in the differential diagnosis of adult liver disease. Screening for alpha-1-antitrypsin globules in periodic acid-Schiff stained liver tissue sections should be considered in certain cases of cryptogenic liver disease in adults, particularly when advanced disease presents suddenly, where micronodular (portal) cirrhosis is unrelated to excessive alcohol use, or where tissue changes exceed those anticipated from serum biochemical abnormalities. In most of these cases, tissue findings from liver biopsy or autopsy, rather than clinical suspicion, led to the diagnosis. The availability of a simple and reliable immunoperoxidase technique, applicable to routinely processed tissue samples, allowed for rapid and specific diagnosis in all cases. This immunocytochemical method has proven its usefulness in the prospective and retrospective tissue diagnosis of alpha-1-antitrypsin deficiency and associated liver disease.
