Method for extracorporeal removal of pathogenic microbe, an inflammatory cell or an inflammatory protein from blood
First Claim
1. A method for treating a subject in need thereof, by extracorporeal removal of a bacterium or pro-inflammatory cytokine, said method comprising:
- a) contacting said subject'"'"'s whole blood with heparin immobilized on a solid substrate, said heparin having a terminal residue, wherein heparin immobilization consists of a single covalent link of said terminal residue to said solid substrate by covalent end-point attachment, under conditions allowing binding of said bacterium or pro-inflammatory cytokine in said subject'"'"'s whole blood sample to the heparin;
b) separating the whole blood from the solid substrate;
c) recovering said whole blood containing a reduced amount of said bacterium or pro-inflammatory cytokine; and
d) reintroducing into said subject said whole blood containing a reduced amount of said a bacterium or pro-inflammatory cytokine.

Abstract
The present invention relates to a method for extracorporeal removal of a pathogenic microbe, an inflammatory cell or an inflammatory protein from mammalian blood/use of a device comprising a carbohydrate immobilized on a solid substrate, said carbohydrate having a binding affinity for a pathogenic microbe, an inflammatory cell or an inflammatory protein, for extracorporeal removal of said pathogenic microbe, inflammatory cell or inflammatory protein from mammalian blood/use of a carbohydrate having a binding affinity for a pathogenic microbe, an inflammatory cell or an inflammatory protein, wherein said carbohydrate is immobilized on a solid substrate, in the preparation of a device for treatment of a condition caused or aggravated by said pathogenic microbe, inflammatory cell or inflammatory protein and a method for treatment of a mammalian subject suffering from a condition caused or aggravated by a pathogenic microbe, an inflammatory cell or an inflammatory protein.
