Recombinant endotoxin-binding protein (rBPI23) attenuates endotoxin-induced circulatory changes in humans.

| Abstract |
In the present study the protective effect of a recombinant endotoxin-binding protein rBPI23 on the circulatory changes in experimental endotoxemia in humans was investigated. In a controlled, blinded crossover study, eight volunteers were challenged twice with an intravenous bolus injection of endotoxin (40 EU/kg body weight), and concurrently received either rBPI23 (1 mg/kg) or placebo (human serum albumin, 0.2 mg/kg). Hemodynamic parameters were obtained non-invasively by means of M-mode, two-dimensional, and Doppler echocardiography. rBPI23 significantly reduced indices of the endotoxin-induced hyperdynamic circulation. rBPI23 treatment significantly reduced increase in cardiac index (P = 0.0156). rBPI23 treatment diminished the endotoxin-induced decrease in systemic vascular resistance index (P = 0.0304). rBPI23 did not prevent the endotoxin-induced rise in body temperature and systolic, diastolic and mean arterial pressure were not significantly different in the rBPI23- and placebo-treatment arm. Both treatment periods showed a small reduction in end diastolic and end systolic volumes. rBPI23 treatment slightly reduced the increase in M-mode ejection fraction and fractional shortening. These results indicate that rBPI23 is capable of attenuating the potentially deleterious circulatory effects of endotoxin in humans.
