Among 424 children with liver disease, 20 had alpha1-antitrypsin deficiency associated with protease inhibitor ZZ phenotype. This disorder manifested itself as cholestasis in early infancy in 19 children. Jaundice and pruritus cleared in 16 of these by 7 months of age, but hepatomegaly and laboratory evidence of mild hepatic dysfunction persisted in all. Biliary cirrhosis and portal hypertension eventually developed or was suspected in eight, and hypoplasia of intraheptic bile ducts was demonstrated in another four. Routine screening revealed intermediate alpha1-antitrypsin deficiency in 16 other children with various types of liver disease. The phenotype in these patients was MZ, MS, or SZ. PAS-positive granules were present in liver of all patients with the ZZ phenotype and in none with other phenotypes. The findings indicate that manifestations and prognosis of this inherited liver disease are extremely variable.

In the last decade, the primary, biliary liver cirrhosis was diagnosed in 17 female patients aged between 33 and 72 years. The most frequent complaint were itching and jaundice. Hepatomegaly and itching predominated in the clinical signs Laboratory tests have shown and increase in alkaline phosphatase activity, gamma-glutamyltranspeptidase, and alanine-aminotransferase activities, accelerated ESR and decrease in blood serum albumins. Immunological abnormalities were found in 15 patients, including 12 with antimitochondrial antibodies. Liver biopsy was carried out in all patients enabling to diagnose the primary cirrhosis in 14 of them. Duration of the disease was between 1 and 9 years. Immunosuppressive treatment was carried out in 10 patients, and symptomatic treatment in the remaining 7 patients. No difference in the effect of therapy on actual health state of patients was seen.

We report on 56 children with sclerosing cholangitis (SC) seen between 1972 and 1992. The first symptoms occurred at a mean age of 3.7 years; 15 infants had neonatal cholestatic jaundice. At diagnosis, cholestatic jaundice was present in 25 children, hepatomegaly in 54, splenomegaly in 41, and ascites in 12. Serum alkaline phosphatase activity was increased in 49 patients and gamma-glutamyltransferase activity in all patients tested. Most often the histopathologic findings were extensive portal fibrosis and neoductular proliferation. Cholangiography showed abnormal intrahepatic bile ducts in all children and abnormal extrahepatic bile ducts in 35 (63%). The children were separated into three groups: (1) those with SC of neonatal onset (27%); (2) those with SC of postneonatal onset associated with another disease (55%)--histiocytosis X in 14 children, immunodeficiency syndromes in 8, chronic inflammatory bowel disease or autoimmune hepatitis in 8, and congenital psoriasis in 1; and (3) those with SC of postneonatal onset without an associated disease (18%). Biliary cirrhosis was present in all but three children after 6 months to 19.3 years of follow-up. Eleven children died of portal hypertension or liver failure, and six died of a complication related to the associated disease. Fifteen children had liver transplantation; 11 of these are alive 6 months to 6 1/2 years later without recurrence of SC. The overall estimated median survival time of children with SC was 10 years from clinical onset. These results indicate that SC should be suspected in all children with a chronic cholestatic disease and increased serum gamma-glutamyl transferase activity, especially when diseases known to be associated with SC are present. The prognosis is poor, but liver transplantation should be considered except in those with severe immunodeficiency syndromes.
