Establishment of a Cohort of Patients With Sepsis-associated Encephalopathy (SAE)

We conducted a prospective observational cohort study of critically ill patients admitted to Emergency Department at a tertiary care hospital. This clinical study was approved by the Ethics Institutional Review Board of Peking Union Medical College Hospital. We identified the sepsis patients according to the Sepsis 3.0 criteria. The SAE was defined as the Glasgow Coma Scale (GCS) score of less than 15 and the Non-SAE group GCS = 15. The control group was the non-infectious patients with acute disease strikes and the healthy control. We are collecting the samples of the included participants, including whole blood, plasma, serum, cerebrospinal fluid, stool and rectal swabs. The total RNA was extracted from the whole blood by PAXgene Blood RNA MDx kit (PreAnalytiX) for RNA sequence. We used the Ultra-high performance liquid chromatography-MS/MS (UHPLC-MS/MS) analysis for detected metabolites. We used the Bio-Plex 200 system (Luminex Corporation, Austin, TX, USA) and Simoa HD-X AnalyzerTM (Quanterix) platform to detect cytokines.
