Plasma levels of granulocyte elastase during hemodialysis: effects of different dialyzer membranes

Abstract

Plasma levels of granulocyte elastase in complex with alpha 1-proteinase inhibitor during hemodialysis were investigated in 15 patients (37.4 +/- 3.2 years) undergoing maintenance hemodialysis (47.0 +/- 12.9 months) with dialyzers made from cellulose hydrate, cuprophan, polymethylmethacrylate, ethylene-vinyl alcohol copolymer, and polyacrylonitrile. Cellulose hydrate membrane caused a maximal increase of the plasma levels of granulocyte elastase in complex with alpha 1-proteinase inhibitor (E-alpha 1PI: 1,659.0 +/- 256.8 ng/ml). Patients dialyzed with polyacrylonitrile dialyzers failed to exhibit comparable plasma levels of granulocyte elastase (E-alpha 1PI: 237.8 +/- 22.9 ng/ml). During hemodialysis plasma E-alpha 1PI values rose to a peak 643.0 +/- 174.7 ng/ml in patients on polymethylmethacrylate dialyzers, to 557.5 +/- 120.0 ng/ml on cuprophan dialyzers, but to only 381.9 +/- 54.0 ng/ml on ethylene-vinyl alcohol copolymer dialyzers. Plasma lysozyme levels decreased significantly in the presence of polyacrylonitrile and polymethylmethacrylate membranes. We conclude that the degree of PMNs stimulation depends on the nature of the dialyzer membrane material. The following membranes induce a reaction of increasing intensity: po...Continue Reading

Bacterial cell walls are made of peptidoglycan (also called murein), which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids. Here is the latest research on bacterial cell wall structures.
