Immunosorbent therapy is the mainstream treatment modality in the clinic, which is a mixture of protein and agar to make an adsorption column for clinical adsorption therapy. Compared with hemoperfusion and hemadsorption, immunosorbent therapy has the advantage of being more selective, and the treatment can significantly and effectively adsorb inflammatory cytokines, immune substances, etc. It is common to treat renal diseases (such as glomerulonephritis), neurological diseases (such as Grinbarr’s syndrome), hematologic diseases (such as hemolytic uremic syndrome), and other diseases, and the treatment effect is more obvious.
