Plasma exchange in anti-glomerular basement membrane disease

Anti-glomerular basement membrane (GBM) disease is a rare autoimmune vasculitis characterised by antibodies directed against the non collagenous (NC1) domain of the α3 chain of type 4 collagen (α3(IV)NC1). Clinical features are typically of a rapidly progressive glomerulonephritis (RPGN) with or without pulmonary haemorrhage. Treatment aims to rapidly remove circulating autoantibodies with plasma exchange and prevent further antibody production...
