Abstract
The serum levels of soluble TNF receptors I (sTNFR I) and sTNFR II were measured frequently in 14 patients with sepsis to evaluate the pattern of these TNF antagonists in relation to TNF alpha, Soluble TNFR I and II could be detected in all samples with significantly higher levels (p < 0.001) compared to healthy controls. The concentration of sTNFR I as well as sTNFR II was significantly higher in nonsurvivors compared to survivors during the first 36 h of sepsis (p < 0.001). Levels remained elevated throughout the evaluation with maximal values in patients who died. A positive correlation exists between both receptors and between soluble receptors and simultaneously obtained sepsis score (p < 0.01) while TNF immunoreactivity detected in 80% of all samples did not correlate to soluble receptor levels or sepsis score. Soluble receptors were constantly found in the circulation representing the inflammatory state throughout the evaluation even when TNF activity was undetectable.
