Study IDST003189
Study TitleUntargeted Metabolomic Profile of Septic Shock in the Emergency Department
Study SummarySeptic shock is a life-threatening condition that arises from a dysregulated host response to infection, resulting in the failure of multiple organ systems and the rapid decline of the patient’s health status. As a medical emergency, early recognition and timely interventions are crucial for improving patient outcomes, particularly in the emergency department setting where septic patients are initially treated. Despite the importance of early identification, current diagnostic tools remain challenges in predicting septic shock at the time of admission. To address these limitations, this study aimed to develop a highly sensitive and specific platform for predicting septic shock in the emergency department. By implementing a supervised algorithm to the metabolic profile, a model based on a 22-metabolite panel was developed to accurately predict septic shock. This approach has the potential to optimize the clinical management of septic shock in the emergency department.

Collection:

Collection ID:CO003301
Collection Summary:Adult patients who visited the emergency department of Taipei Veterans General Hospital between Nov. 2018 and Feb. 2019 were prospectively enrolled with approval from the Institutional Review Board. Blood samples were obtained during routine clinical testing upon admission before initial treatment. These samples were collected in serum separator tubes, left to clot at room temperature for 1 h, and then centrifuged at 3000 rpm at 4 °C for 20 min. The resulting supernatant sera were promptly stored at -80°C before subsequent analysis.
Sample Type:Blood (serum)

Treatment:

Treatment ID:TR003317
Treatment Summary:The samples detailed in this study did not undergo any treatment.

Sample Preparation:
