Evaluation of a Multivalent Transcriptomic Metric for Diagnosing Surgical Sepsis and Estimating Mortality Among Critically Ill Patients

Abstract: Key Points Question Can a whole-blood RNA transcriptomic metric (IMX) obtained in the first 12 hours after intensive care unit (ICU) admission accurately measure the presence of bacterial infection and risk for sepsis mortality? Findings In this diagnostic and prognostic study including 200 patients with critical illness enrolled from a surgical ICU, the IMX transcriptomic metric was equivalent to or significantly better than the sequential organ failure as… Show more

“…Study Designs: This study performed transcriptomic analyses on samples from two single-site, prospective, observational cohorts that enrolled a total of 522 patients admitted to non-cardiac, surgical ICUs and were classi ed as either (1) critically ill patients with a diagnosis of sepsis (Septic), or (2) non-septic critically-ill patients, at high risk for subsequently developing sepsis (At-Risk or Non-Septic; Fig. 1) [25,26].…”

“…The second prospective diagnostic and prognostic study (INF-06) was conducted between July 2020 and July 2021 [25] and enrolled two cohorts of critically ill patients at the time of surgical ICU admission (NCT04414189). One cohort included patients with a suspected diagnosis of sepsis admitted to the ICU for protocolized sepsis management, as in previously described study.…”

“…A combination of three non-overlapping signatures identified from a multi-cohort analysis (Sweeney et al, 2015;Sweeney et al, 2018b) has led to TriVerity (formerly known as InSepTM HostDxTMSepsis and Inflammatix) (Mayhew et al, 2020). This 29-gene expression-based test with a turnaround time Frontiers in Genetics frontiersin.org 10 less than 30 min is expected to identify the presence, type (bacterial or viral) and risk of mortality of infection (Mayhew et al, 2020;Bauer et al, 2021;Safarika et al, 2021;Brakenridge et al, 2022;Galtung et al, 2022). A Point-of-Care Test claiming to distinguish bacterial from viral infections in children is in its infancy (Pennisi et al, 2021).…”

“…Identification of sepsis remains a major challenge to implement prompt treatment in surgical patients suffering from this condition. Correct and quick discrimination between sepsis and surgical related inflammation allows to early implement measures aimed to control the infection source with surgery or antibiotics (1,2). Biomarkers are a potential useful tool to improve sepsis detection, complementary to clinical information and to image and/or microbiological tests, but the information regarding biomarkers must be provided in minutes in order to be useful (3,4) .…”
