[Liver disease in homozygous alpha1-antitrypsin deficiency (author's transl)].

: Among twelve patients with homozygous alpha1-antitrypsin deficiency (Pi-type Z), five cases of infantile liver disease were diagnosed. The course of the disease was extremely variable; only one patient died of liver cirrhosis at the age of fourteen. In four cases the clinical, biochemical and histological (2 cases) findings became normal over a follow-up period of one to fifteen years. The results of these observations demonstrate that in alpha1-antitrypsin deficiency even when associated with proven liver disease the prognosis need not be unfavorable.
