ELABELA（ELA）: We Collected Blood Samples From Septic Shock Patients and Measured ELABELA, Creatinine, and NGAL Levels. Survival After 7 Days Was Recorded and Analyzed to Evaluate the Potential of Serum ELABELA as an Early Diagnostic Marker for Sepsis-associated Acute Kidney Injury.
Study Details
Study Description
Brief Summary
The investigators selected patients diagnosed with sepsis who were admitted to the Intensive Care Unit (ICU) of Huai'an First People's Hospital between June 2022 and December 2023, as well as healthy individuals with normal kidney function during the same period, for the research. The investigators collected blood samples from patients with septic shock or sepsis at 6 hours, 12 hours, 24 hours, 48 hours, 3 days, 5 days, and 7 days after diagnosis， and also collected blood samples from the healthy individuals. The blood samples were stored in gel separation vacuum tubes containing heparin as an anticoagulant. The supernatant was removed and stored at -80°C, and the levels of plasma ELA (enzyme-linked immunosorbent assay) were measured using a standardized ELA kit. Additionally, serum NGAL (neutrophil gelatinase-associated lipocalin) and creatinine levels were measured simultaneously. The subjects were divided into three groups based on the KDIGO diagnostic criteria: sepsis-associated acute kidney injury (S-AKI) group, sepsis non-AKI group, and normal control group. Finally, the data were analyzed to determine the early diagnostic value of ELA for S-AKI. Approximately 70 specimens were collected in total.
