Abstract

To evaluate if the assessment of coagulation abnormalities at ED admission could improve prognostic assessment of septic patients. This report utilizes a portion of the data collected in a prospective study, with the aim to identify reliable biomarkers for an early sepsis diagnosis. In the period November 2011-December 2016, we enrolled 268 patients, admitted to our High-Dependency Unit with a diagnosis severe sepsis/septic shock. Study-related blood samplings were performed at ED-HDU admission (T0), after 6 h (T6) and 24 h (T24): D-dimer, thrombin-antithrombin complex (TAT) and prothrombin fragment F1 + 2 levels were analyzed. The primary end-points were day-7 and in-hospital mortality. Day-7 mortality rate was 16%. D-dimer (T0: 4661 ± 4562 µg/ml vs 3190 ± 7188 µg/ml; T6: 4498 ± 4931 µg/ml vs 2822 ± 5623 µg/ml; T24 2905 ± 2823 µg/ml vs 2465 ± 4988 µg/ml, all p < 0.05) and TAT levels (T0 29 ± 45 vs 22 ± 83; T6 21 ± 22 vs 15 ± 35; T24 16 ± 19 vs 13 ± 30, all p < 0.05) were higher among non-survivors compared to survivors. We defined an abnormal coagulation activation (COAG+) as D-dimer > 500 µg/ml and TAT > 8 ng/ml (for both, twice the upper normal value). Compared to COAG-, COAG+ patients showed higher lactate levels at the earliest evaluations (T0: 3.3 ± 2.7 vs 2.5 ± 2.3, p = 0.041; T6: 2.8 ± 3.4 vs 1.8 ± 1.6, p = 0.015); SOFA score was higher after 24 h (T24: 6.7 ± 3.1 vs 5.4 ± 2.9, p = 0.008). At T0, COAG+ patients showed a higher day-7 mortality rate (HR 2.64; 95% CI 1.14-6.11, p = 0.023), after adjustment for SOFA score and lactate level. Presence of abnormal coagulation at ED admission shows an independent association with an increased short-term mortality rate.
