Adolescents with alpha1-antitrypsin deficiency have high alpha2-macroglobulin and low neutrophil lipocalin and elastase levels in plasma
Eighteen-year-old adolescents with alpha1-antitrypsin (alpha1AT) deficiency have mostly normal lung function tests. We hypothesized that compensatory increases in other protease inhibitors and/or a decreased leukocyte activity might favorably affect the protease/protease-inhibitor balance in alpha1AT-deficient adolescents. At the age of 18 y 46 PiZZ (severe deficiency), 22 PiSZ (moderate deficienc
