Abstract
OBJECTIVES: We evaluated serum levels of CXCL12 in patients with severe sepsis/septic shock and controls.
METHODS: We enrolled 27 patients admitted to our emergency department with severe sepsis/septic shock and 20 healthy controls. Complete blood count, serum levels of CXCL12, C-reactive protein, lactate, Charlson comorbidity index, sequential organ failure score on hospital admission, and inhospital mortality were evaluated at baseline (T0) and after 24 hours (T24).
RESULTS: Mean serum levels of CXCL12 were higher in patients with severe sepsis/septic shock than in healthy subjects (3121 vs 1991 pg/mL; P < .001). We also found that patient who survived had lower serum levels of CXCL12 than those who died (2630 vs 3957 pg/mL; P < .001) but still higher than controls (2630 vs 1991 pg/mL; P = .001) on admission. CXCL12 serum levels were higher in patients with serum lactate greater than 4 mmol/L.
CONCLUSIONS: Our data suggest a possible role for CXCL12 as a prognostic marker in severe sepsis/septic shock and give background evidence for larger trials to evaluate the pathophysiologic and clinical role of CXCL12 in sepsis, with respect to other markers of inflammation and hypoxia.
