In the present study, some of the “classic” cytokine genes like IL1B, IL6, IL8, IL10, and TNF showed a very rapid transcription onset with, except for IL8, a peak up-regulation coinciding with early clinical symptoms such as tachycardia, severely decreased borborygmus, and profound leukopenia. This evidence concerns the gene CXCL8 and Decreased total leukocyte count.
