Abstract
Circulatory shock is defined syndromically as hypotension associated with tissue hypoperfusion and often subcategorized according to hemodynamic profile (e.g., distributive, cardiogenic, hypovolemic) and etiology (e.g., infection, myocardial infarction, trauma, among others). These shock subgroups are generally considered homogeneous entities in research and clinical practice. This current definition fails to consider the complex pathophysiology of shock and the influence of patient heterogeneity. Recent translational evidence highlights previously under-appreciated heterogeneity regarding the underlying pathways with distinct host-response patterns in circulatory shock syndromes. This heterogeneity may confound the interpretation of trial results as a given treatment may preferentially impact distinct subgroups. Re-analyzing results of major 'neutral' treatment trials from the perspective of biological mechanisms (i.e., host-response signatures) may reveal treatment effects in subgroups of patients that share treatable traits (i.e., specific biological signatures that portend a predictable response to a given treatment). In this review, we discuss the emerging literature suggesting the existence of distinct biomarker-based host-response patterns of circulatory shock syndrome independent of etiology or hemodynamic profile. We further review responses to newly prescribed treatments in the intensive care unit designed to personalize treatments (biomarker-driven or endotype-driven patient selection in support of future clinical trials).

Abstract
INTRODUCTION Acute traumatic coagulopathy (ATC) is an endogenous impairment in hemostasis that often contributes to early mortality after trauma. Endothelial glycocalyx damage is associated with trauma-induced coagulation abnormalities; however, the specific relationship between hyaluronan (HA), a key glycocalyx constituent, and ATC has not been evaluated. METHODS We performed a secondary analysis of prospectively collected data from a recent study in which trauma patients (>18 years) admitted to our Level I trauma center with an ABC Score≥2 were enrolled. Partial thromboplastin time (PTT), international normalized ratio (INR), and thromboelastography (TEG) parameters were recorded at arrival. Injury characteristics and clinical outcomes were obtained. Plasma HA levels were measured in healthy controls (HC) and in trauma subjects at arrival (t = 0 h) and 12, 24, and 48 h. ATC was defined as admission INR>1.2 or PTT≥36.5 s. Comparisons of HA levels were assessed, and Spearman's correlations were performed between 0 h and 24 h HA levels, coagulation measures and clinical outcomes. P values < 0.05 were considered significant. RESULTS Forty-eight trauma patients and 22 controls were enrolled for study. Sixteen trauma subjects were coagulopathic at admission. HA levels in subjects with ATC were higher than non-coagulopathic subjects at all time points and elevated above HC levels at 24 and 48 h. At arrival, HA levels correlated with TEG R-time, PTT, and INR. HA levels at 24 h correlated with increased transfusion requirements and intensive care unit and hospital lengths of stay. CONCLUSION Shed HA is associated with early coagulation abnormalities in trauma patients, which may contribute to worse outcomes. These findings highlight the need for additional studies to evaluate the mechanistic role of HA in ATC.
