Chromogenic endotoxin determination in blood — clinical relevance

Summary In a pilot study in 400 patients LPS-quantification in blood using chromogenic substrates, bacterial cultures and bacterial quantification were performed. Decreased plasma levels of antithrombin III and plasminogen were early predictors of gram-negative septicemia, which already were apparant 3 days prior to the first positive LPS-test. It is concluded that daily determinations of LPS may reduce the delay in proper antibiotic therapy.
