Lipopolysaccharide (LPS, endotoxin) was quantified in plasma and cerebrospinal fluid (CSF) collected simultaneously from patients with systemic meningococcal disease. High levels (median, 3800 ng/L; range, 750-14,000) were present in plasma and low levels (median, 40 ng/L; range, less than 25-165) in CSF of patients with fulminant septicemia. Conversely, high levels (median, 2500 ng/L; range, less than 25-500,000) in CSF and low or undetectable levels (median, less than 25 ng/L; range, less than 25-210) in plasma were associated with meningitis without septic shock. Levels of LPS were significantly correlated with protein levels in CSF (r = .50, P = .01) and inversely correlated with the ratio of glucose in CSF to that in blood (r = -.62, P = .0005). LPS level in CSF greater than 800 ng/L was significantly associated with greater than or equal to 10(9) leukocytes/L, protein levels greater than 0.5 g/L, and a glucose ratio less than 0.5. Thus, quantification of LPS levels in the plasma and CSF in systemic meningococcal disease is a better predictor of pathophysiologic events than is demonstrating the presence of live bacteria as in conventional culture.
