Abstract: The effects of intravenous immunoglobulin G (ivIG) on the hepatic microvascular inflammatory response to sepsis were studied in rats by in vivo microscopy. High doses of ivIG (300 mg/kg bw) (Sandoglobulin or rat IgG) significantly improved the 48 h survival of septic rats from 25-66% when ivIG was given before or immediately after cecal ligation and puncture. Circulating endotoxin also was significantly reduced. Eight hours after inducing sepsis, the average number of leukocytes adhering to the sinusoidal endothelium increased 15-fold and the average decrease in the number of perfused sinusoids was 22%. IvIG administration minimized these responses. In both septic and nonseptic animals, ivIG also reduced the phagocytic activity of Kupffer cells. The results suggest that high doses of ivIG not only reduce lethality but also limit hepatic microcirculatory dysfunction during sepsis by minimizing leukocyte-endothelial interactions that may be a result of reducing circulating endotoxin and modifying Kupffer cell function.
