Failure of neutrophil chemotactic function in septic patients*

Septic patients present suppressed neutrophil chemotactic responses to FMLP and leukotriene B4 stimuli compared with healthy controls. This is accompanied by increased serum concentrations of nitrate. The impairment of neutrophil chemotaxis was observed mainly in the cells obtained from nonsurvivor patients and may thus be an additional factor contributing to disease outcome.
