Over a 6 month period, in 192 patients admitted to the intensive care unit (ICU), a longitudinal analysis of whole blood lipopolysaccharide (LPS)-induced ex vivo cytokine production was performed on a daily basis until discharge from the ICU or death. Twenty-one patients with proven infections were in septic shock for the first time and for at least 3 days' duration. Ex vivo LPS-inducible release of granulocyte colony-stimulating factor (G-CSF) was upregulated and that of TNF-α was downregulated in patients with septic shock, regardless whether they survived or died. In conclusion, LPS-induced ex vivo TNF-α and G-CSF cytokine release by monocytes is regulated differentially in patients with septic shock. Since upregulation of LPS-induced production of G-CSF occurred earlier in survivors than in non-survivors, rapidly elevated and sustained G-CSF responsiveness may contribute to survival in septic shock.
