The New Antiendotoxin Strategies
抗内毒素治疗的新策略

Lipopolysaccharide(LPS)is important in the pathogenesis of sepsis infected by gram\|negative bacteria in humans,and part or all of this pathophysiology is mediated by a complex secondary inflammatory response.Administration of purified LPS or a variety of LPS\|free recombinant mediators can reproduce much of the pathophysiology of gram\|negative sepsis.There has been an explosion of new information over the last several years regarding the interactions of LPS with proteins and cells.Blocking sepsis at the bacterial toxin level is appealing because it is upstream,so that the secondary pathologic inflammatory cascade may be limited or prevented.A variety of antiendotoxin strategies have been proposed.Therapies under investigation include agents that bind and neutralize LPS,agents or systems that enhance LPS clearance,and agents that inhibit LPS interaction with serum elements or cellular receptors.
