Clinical, histological (including electron-microscopic), immunohistochemical and genetic studies were performed on two infants with alpha1-antitrypsin deficiency. The clinical picture was one of neonatal biliary stasis. Liver biopsies revealed multiple cytoplasmic acidophilic bodies within many cells of the liver parenchyma which were strongly periodic acid-Schiff-positive, diastase-resistant and stained selectively with fluorescein-labelled rabbit antihuman alpha1-antitrypsin. Ultrastructurally, the bodies were situated within enlarged cisterns of the endoplasmatic reticulum. Both infants were of the protease inhibitor (Pi) phenotype ZZ, having inherited on PiZ gene from each parent. Results of Pi typing of both families were consistent with an autosomal co-dominant inheritance. Both infants are clinically well except for slight hepatomegaly at one year of age. But transaminase and gamma-glutamyl transpeptidase activities have remained elevated.

UI MeSH Term Description Entries
D007120 Immunochemistry Field of chemistry that pertains to immunological phenomena and the study of chemical reactions related to antigen stimulation of tissues. It includes physicochemical interactions between antigens and antibodies.
D007136 Immunoglobulins Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.

D007223 Infant A child between 1 and 23 months of age. Infants
D007931 Leucyl Aminopeptidase A zinc containing enzyme of the hydrolase class that catalyzes the removal of the N-terminal amino acid from most L-peptides, particularly those with N-terminal leucine residues but not those with N-terminal lysine or arginine residues. This occurs in tissue cell cytosol, with high activity in the duodenum, liver, and kidney. The activity of this enzyme is commonly assayed using a leucine arylamide chromogenic substrate such as leucyl beta-naphthylamide.
