Zusammenfassung: | Sepsis remains one of the main causes of death in intensive care unit (ICU) worldwide, despite all technological and scientific advances. Microvesicles (MV) have become promising biomarkers for quick and accurate monitoring of several illnesses. The aim of this pilot study was to characterize and evaluate the performance of MV as biomarker of clinical outcome in septic and trauma patients. For this purpose, 39 subjects, both genders, aging from 18 to 85 years were included in three groups referred as Sepsis, Trauma and Healthy Control. Kinetic analysis of MV was carried out at four consecutive time points: admission (baseline)/T1, 24 h/T2, 72 h/T3 and outcome/T4 of discharge or death. At admission, an overall increase in total MV (Annexin V+) was observed in Sepsis.MV CD14+ (monocytes) was a putative biomarker to identify trauma patients, while MV CD3+ (T-cells) and CD41+ (platelets) were qualified to discriminated Trauma from Sepsis. Sepsis (Death) presented an increase in MV Annexin V+, CD45+, CD16+, CD14+, and CD41+ in comparison to Sepsis (Discharge). Moreover, Trauma (Death) presented an increase of MV CD3+ and CD235+ as compared to Trauma (Discharge). Analysing the ROC curve of specific MV evaluated according to performance, an accuracy of 100% was found to segregate the outcome in sepsis, and 95% in trauma. Our findings suggest that MV might be useful as a potential role in discriminating outcome in patients with sepsis/septic shock and trauma with high accuracy. However, further studies with a larger number of participants will be necessary to validate our findings.

•Biomarker identification can be useful in clinical and evolutionary management of septic patients.•The kinetics of microvesicles (MV) may represent a group of biomarkers capable of assessing the profile of septic patients.•MV can be accurate biomarkers to accurately monitor sepsis and trauma clinical outcome.•Total MV, neutrophils and monocytes derived MV are useful parameters to discriminate clinical outcome in sepsis. |
