Abstract
We studied blood MIP-1α and IL-8 in 38 septic patients and 5 healthy volunteers. Both chemokines were undetectable in the healthy volunteers. In sepsis, serum MIP-1α was detected in 45% of the patients and IL-8 in 84%. The levels of MIP-1α, but not of IL-8, correlated with CRP, IL-6 and TNFα levels. Complication, including various organ failures and mortality, showed no correlation with serum MIP-1α levels. In contrast, we found increased levels of serum IL-8 in septic patients with disseminated intravascular coagulation, central nervous system (CNS) dysfunction or renal failure, and the mortality rate was higher in the IL-8-detectable group than in the IL-8 undetectable group (50% vs 0%,p<0.05). In conclusion, the production of both MIP-1α and IL-8 was increased and initially detectable levels of circulating IL-8 predicted high mortality in sepsis.
Objective
To determine the significance of the C-C chemokine MIP-1α and the C-X-C chemokine IL-8 in sepsis.
Design
Prospective study.
Setting
Clinical investigation, emergency department and general intensive care unit of university hospital.
Patients and participants
38 septic patients and 5 healthy volunteers were studied. Sepsis was diagnosed following the criteria formulated by ACCP/SCCM.
Interventions
10–20 ml of blood was drawn from each patient at the time of initial diagnosis of sepsis.
Measurements and results
MIP-1α and IL-8 were determined by sand-wich ELISA. Both chemokines were undetectable in the healthy volunteers. In sepsis, serum MIP-1α was detected in 45% of the patients and IL-8 was detected in 84%. The levels of MIP-1α, but not of IL-8, correlated with CRP, IL-6 and TNFα levels. Complications, including various organ failures and mortality, showed no correlation with serum MIP-1α levels. In contrast, we found increased levels of serum IL-8 in patients with disseminated intravascular coagulation (DIC) (p<0.05), central nervous system (CNS) dysfunction (p<0.05), renal failure (p<0.01) and the mortality rates were higher in the IL-8 detectable group than in the IL-8 undetectable group (50% vs 0%,p<0.05).
Conclusions
The production of MIP-1α and IL-8 was increased in sepsis. Furthermore, an initially detectable level of circulating IL-8, but not MIP-1α, predicted a high mortality in sepsis diagnosed according to the ACCP/SCCM criteria.
