[Study of serum levels of alpha 1-antitrypsin and alpha macroglobulins in children with glomerulonephritis].

To define the clinico-pathogenetic importance of alpha 1-inhibitor of proteinases and alpha 2-macroglobulin of the blood in children with glomerulonephritis, a study was made of the phenotype of alpha 1-inhibitor of proteinases and its concentration in the blood serum of 156 patients with different clinical forms of glomerulonephritis. Overall 1290 practically healthy children were examined as control. The patients suffering from glomerulonephritis did not demonstrate phenotypes responsible for acute deficiency of alpha 1-inhibitor of proteinases (PISS, PISZ).
