BACKGROUND: A systemic inflammatory response is observed after cardiopulmonary resuscitation. We investigated two novel inflammatory markers, pentraxin 3 (PTX3) and soluble suppression of tumorigenicity 2 (sST2), in comparison with the classic high-sensitivity C-reactive protein (hsCRP), for prediction of early multiple organ dysfunction syndrome (MODS), early death, and long-term outcome after out-of-hospital cardiac arrest. METHODS: PTX3, sST2, and hsCRP were assayed at ICU admission and 48 h later in 278 patients. MODS was defined as the 24 h non-neurological Sequential Organ Failure Assessment (SOFA) score ≥12. Intensive care unit (ICU) death and 12-month Cerebral Performance Category (CPC) were evaluated. RESULTS: In total, 82% of patients survived to ICU discharge and 48% had favorable neurological outcome at 1 year (CPC 1 or 2). At ICU admission, median plasma levels of hsCRP (2.8 mg/L) were normal, while levels of PTX3 (19.1 ng/mL) and sST2 (117 ng/mL) were markedly elevated. PTX3 and sST2 were higher in patients who developed MODS (p<0.0001). Admission levels of PTX3 and sST2 were also higher in patients who died in ICU and in those with an unfavorable 12-month neurological outcome (p<0.01). Admission levels of PTX3 and sST2 were independently associated with subsequent MODS [OR: 1.717 (1.221-2.414) and 1.340, (1.001-1.792), respectively] and with ICU death [OR: 1.536 (1.078-2.187) and 1.452 (1.064-1.981), respectively]. At 48 h, only sST2 and hsCRP were independently associated with ICU death. CONCLUSIONS: Higher plasma levels of PTX3 and sST2, but not of hsCRP, at ICU admission were associated with higher risk of MODS and early death.

Abstract

BACKGROUND: A systemic inflammatory response is observed after cardiopulmonary resuscitation. We investigated two novel inflammatory markers, pentraxin 3 (PTX3) and soluble suppression of tumorigenicity 2 (sST2), in comparison with the classic high-sensitivity C-reactive protein (hsCRP), for prediction of early multiple organ dysfunction syndrome (MODS), early death, and long-term outcome after out-of-hospital cardiac arrest. METHODS: PTX3, sST2, and hsCRP were assayed at ICU admission and 48 h later in 278 patients. MODS was defined as the 24 h non-neurological Sequential Organ Failure Assessment (SOFA) score ≥12. Intensive care unit (ICU) death and 12-month Cerebral Performance Category (CPC) were evaluated. RESULTS: In total, 82% of patients survived to ICU discharge and 48% had favorable neurological outcome at 1 year (CPC 1 or 2). At ICU admission, median plasma levels of hsCRP (2.8 mg/L) were normal, while levels of PTX3 (19.1 ng/mL) and sST2 (117 ng/mL) were markedly elevated. PTX3 and sST2 were higher in patients who developed MODS (p<0.0001). Admission levels of PTX3 and sST2 were also higher in patients who died in ICU and in those with an unfavorable 12-month neurological outcome (p<0.01). Admission levels of PTX3 and sST2 were independently associated with subsequent MODS [OR: 1.717 (1.221-2.414) and 1.340, (1.001-1.792), respectively] and with ICU death [OR: 1.536 (1.078-2.187) and 1.452 (1.064-1.981), respectively]. At 48 h, only sST2 and hsCRP were independently associated with ICU death. CONCLUSIONS: Higher plasma levels of PTX3 and sST2, but not of hsCRP, at ICU admission were associated with higher risk of MODS and early death.
