Liver pathology in alpha1-antitrypsin deficiency. A review.
Alpha1-antitrypsin deficiency (AATD), in addition to its association with chronic pulmonary disease, is reported with liver disease. Twenty per cent of Pi-type ZZ AATD infants present with a cholestatic type of neonatal hepatitis and develop a slowly progressive cirrhosis, and most die before adult life. Ten per cent of Pi-type ZZ adults develop cirrhosis. They have an increased frequency of primary liver carcinoma. In Z homozygotes and heterozygotes specific globules, due to accumulation of a type of alpha1-antitrypsin, are seen in liver cells. They are thought not to be hepatotoxic but to render the liver cell more susceptible to damage by an additional factor.
