Increased levels of circulating interleukin 6 in burn patients.
The serum levels of interleukin 6 (IL-6) were determined in a population of burn patients. In all patients, IL-6 levels were increased over a 3-week interval with peak concentrations reached during the first week after injury. Patients receiving intravenous polymyxin B therapy according to a regimen designed to reduce endotoxemia manifested greatly reduced levels of both circulating endotoxins and IL-6. Certain patients not treated with polymyxin B showed extraordinarily large increases in IL-6 which were associated with lethal or life-threatening clinical complications. Increased IL-6 levels were also associated with decreased percentage of circulating T cells and corresponding increases in B cells. However, IL-6 did not produce any direct inhibitory effects in vitro on T cell representation or function.
