  Background and objective: Alpha-1-antitrypsin deficiency presenting as neonatal cholestasis occurs in a small percentage of affected individuals. The prognosis is variable, from “healing” to liver cirrhosis and/or severe hepatocellular failure, requiring liver transplantation. We researched for predictors of outcome, including the effect of ursodeoxycholic acid. Methods: Retrospective cohort study of 27 cases of neonatal cholestasis due to alpha-1-antitrypsin deficiency, in the period between 1985 and 2013. Inclusion criteria: patients with neonatal cholestasis and ZZ phenotype. Exclusion criteria: presence of other diagnosis or known risk factors for developing neonatal cholestasis. We analyzed several clinical, biochemical, histological and therapeutic variables. Patients were categorized into two groups: favorable outcome (n=18), unfavorable outcome (n=9). We also divid..
