    Abstract:
    Alpha-1-antitrypsin deficiency is an inborn metabolism error which can cause emphysema and liver disease. As regards the pathophysiology of liver disease, this deficiency is poorly understood, and it is also not known why only a small proportion of Pi ZZ individuals progress towards cirrhosis and liver failure. Since there is no specific therapy for end-stage liver disease associated with alpha-1-antitrypsin deficiency, patients are considered candidates for liver transplantation. In this paper, the natural history of 16 children who underwent liver transplantation is reviewed. Fourteen patients had neonatal cholestasis as a first symptom of the disease and hepatosplenomegaly was present in all children by the age of 12 months. In 11 children, jaundice recurred, always with liver function deterioration. Two patients had a histological paucity of interlobular bile ducts and required early transplantation due to rapid progression of liver failure. At the time of pretransplant assessment, all the patients in this study had portal hypertension and seven of them had experienced at least one episode of gastrointestinal bleeding. One child had moderate intrapulmonary shunts with hypoxemia, but the others had normal spirometry and blood gases. There was no other extrahepatic complication of alpha-1-antitrypsin deficiency. Eighteen orthotopic liver transplantations were performed in 16 patients. One patient died 8 days after retransplantation due to graft necrosis. Fifteen patients (94%) were alive after a median follow-up of 22 months with an excellent quality of life, normal serum alpha-1-antitrypsin levels and without evidence of liver disease recurrence or pulmonary complications.(ABSTRACT TRUNCATED AT 250 WORDS)
