[Evaluation of nuclear factor-KappaB and I Kappa B mRNA expression in determining the prognosis of multiple organ dysfunction syndrome].
OBJECTIVE
To observe the value of nuclear factor-KappaB(NF-KappaB) and I Kappa B mRNA expression estimation on determining the prognosis of patients with multiple organ dysfunction syndrome (MODS).


METHODS
Forty-three MODS patients were divided into two groups based on their prognosis: the survivor group (n =28) and the non-survivor group (n=15). Another group of 10 healthy persons served as normal control group. The expression of NF-Kappa B and I Kappa B-alpha mRNA levels in monocytes/neutrophils of patients and controls were detected by reverse transcription-polymerase reaction (RT-PCR), and the results were compared among groups.


RESULTS
The expression of NF-KappaB mRNA levels of MODS patients was higher than that of normal control group(1. 35+/-0.53 vs. 0.74+/-0.25, P<0.01),and the expression of I Kappa B-alpha mRNA levels were lower than those of the control group (1. 24+/-0.60 vs. 1. 97+/-0.71,P<0.01). There was no significant difference in NF-KappaB mRNA levels between the survivor group and the non-survivor group (1. 27+/-0.37 vs. 1.39+/-0.60,P>0.05), but the expression of I Kappa B-alpha mRNA levels in the non-survivor group was significantly lower than that of survivors(0.94+/-0.46 vs. 1. 40+/-0.61, P<0.05). The results suggested that there was a negative correlation between the expression of I Kappa B-alpha mRNA level and acute physiology and chronic health evaluation II (APACHE II)(r=-0.340, P<0.05). Moreover, when the cutoff value of the expression of I Kappa B-alpha mRNA level was 1. 34, the Youden index was 0.51, and it was the highest in all the cutoff values, and the specificity was 90.72%,the sensitivity was 60.75%.


CONCLUSIONS
The expression of I Kappa B-alpha mRNA level can be a useful guide for determining the prognosis of patients with MODS.
