[Specificity and serum concentrations of tumor necrosis factor in septic shock].
Several lines of evidence implicate tumor necrosis factor (TNF), a cytokine produced by monocytes-macrophages, in the systemic manifestations of shock induced by Gram-negative bacteria. Whether the increase of circulating TNF levels is specific to septic shock as compared to sepsis without shock or to non-septic shock is still unclear. Since TNF values recorded at the time of admission to the hospital vary widely, statistical analysis has not been possible. ⋯ Repeated measurements were made during the first 3 days of septic shock in 10 patients. The circulating TNF level, determined upon admission, appears to be neither specific nor predictive of the outcome of septic shock. In contrast, persistently high levels of circulating TNF seem to be well correlated with a poor prognosis, since 5 out of 6 patients with elevated TNF values died of septic shock.
