title: Alpha-1-antitrypsin deficiency in early childhood.
abstract: Alpha-1-antitrypsin deficiency (AATD), which predisposes liver disease in children, is often undiagnosed. Isoelectric focusing in 161 infants with liver dysfunction revealed 14.7% severe and 12.2% moderate AATD. Positive PAS-D and immunohistochemical staining was found in 60% of severe AATD, but in moderate AATD, only immunohistochemistry was positive in 100%. Bilirubinostasis, hepatomegaly, splenomegaly, cholestasis, hepatomegaly associated with cholestasis, acholia, high transaminases, and low birthweight were significantly more frequent in severe than in moderate AATD. Both AATDs showed significant portal inflammation, hepatic fibrosis, and viral infection. Early screening in children with liver dysfunction can contribute to the successful detection of AATD.
