Abstract

AIM: To investigate the clinical utility of interleukin-6 (IL-6), procalcitonin (PCT), and C-reactive protein (CRP) as predictive markers in consideration of the time-course changes in critically ill patients with organ dysfunction.

METHODS: Serum levels of IL-6, PCT, CRP, and Sequential Organ Failure Assessment (SOFA) scores were measured sequentially in 92 patients during their initial 5 days following admission to the intensive care unit. Maximum values were analyzed. Patients were assigned to a low ( ≤ 8), intermediate ( > 8 and ≤ 16), or high ( > 16 and ≤ 24) SOFA score group.

RESULTS: There were significant differences in the maximum serum levels of IL-6 and PCT among the three SOFA score groups (IL-6,

CONCLUSION: Serum levels of IL-6 reflected the severity of organ dysfunction in critically ill patients most accurately compared to PCT and CRP. Interleukin-6 elevated soonest from the insult and reached its peak earlier than SOFA score.
