Abstract

Endotoxin levels were measured in the blood and cerebrospinal fluid (CSF) of control individuals and 2 groups of patients with African sleeping sickness. Endotoxin levels were markedly elevated in the blood (infected groups mean endotoxin values 40.2 pg/ml and 53.8 pg/ml, compared to control 11.6 pg/ml, P < 0.0001 for both increases) and CSF (infected groups mean endotoxin values 45.8 pg/ml and 50.1 pg/ml compared to control 6.3 pg/ml, P < 0.0001 for both increases) of the patients. The levels were reduced 6 weeks following different drug treatments in the 2 groups (blood levels to mean 33.8 pg/ml and 28.5 pg/ml; CSF levels to 37.4 pg/ml and 27.0 pg/ml). The blood endotoxin values correlated with the CSF values before treatment (r = 0.74 and 0.57 for the 2 groups; P < 0.0001 for both) and after treatment (r = 0.57 and 0.56 for the 2 groups; P < 0.0001 for both). It is concluded that raised endotoxin equilibrates in the blood and CSF compartments, and may contribute significantly to the pathology of sleeping sickness.
