The relationship between fluctuating cytokine concentrations in
plasma and the outcome of sepsis is complex. We postulated that early
measurement of the activation of nuclear factor

Predictive Value of Nuclear Factor
B Activity
and Plasma Cytokine Levels in Patients with Sepsis
B (NF-
B), a
transcriptional regulatory protein involved in proinflammatory cytokine
expression, may help to predict the outcome of sepsis. We determined
NF-
B activation in peripheral blood mononuclear cells of 34 patients
with severe sepsis (23 survivors and 11 nonsurvivors) and serial
concentrations of inflammatory cytokines (interleukin-6, interleukin-1,
and tumor necrosis factor) and various endogenous antagonists in
plasma. NF-
B activity was significantly higher in nonsurvivors and
correlated strongly with the severity of illness (APACHE II score),
although neither was related to the cytokine levels. Apart from NF-
B
activity, the interleukin-1 receptor antagonist was the only cytokine
tested whose level in plasma was of value in predicting mortality by
logistic regression analysis. These results underscore the prognostic
value of early measurement of NF-
B activity in patients with severe sepsis.
