Anti-alpha 3(IV) collagen autoantibodies have been implicated in the pathogenesis of Goodpasture syndrome, an autoimmune disorder causing glomerulonephritis and pulmonary hemorrhage. Currently treatment involves removal of the entire IgG fraction of plasma by plasmapheresis or adsorption to protein A. The present study shows that the anti-alpha 3(IV)NC1 autoantibodies can be removed from plasma specifically and quantitatively by affinity chromatography utilizing either alpha 3 NC1 domain of bovine type IV collagen or recombinant alpha 3 NC1 domain of human type IV collagen immobilized to agarose beads. This study shows the feasibility of using affinity chromatography, as an alternative to plasmapheresis, to exclusively remove the pathogenic autoantibodies from the plasma of patients with Goodpasture syndrome.
