简要总结
This study was conducted to explore the association between ulinastatin treatment and the incidence of sepsis-associated encephalopathy (SAE) in patients with sepsis. The study was divided into two phases: first, a multicenter retrospective observational cohort: to evaluate the correlation between ulinastatin treatment and the risk of SAE; second, a single center prospective observational cohort: to further explore the association between ulinastatin treatment and SAE.
详细描述
This study consisted of two parts: a retrospective, multicenter observational derivation cohort and a prospective, single-center observational validation cohort. Both parts of the study included adult patients admitted to the intensive care unit of Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology. The first part of the study, being retrospective in nature, was exempted from obtaining informed consent. However, all participants in the second part of the study signed a written informed consent form. The first part of the study retrospectively collected adult patients with sepsis according to the inclusion and exclusion criteria, explored the factors related to sepsis-related encephalopathy, and analyzed the correlation between the use of ulinastatin treatment and the occurrence of SAE. The second part of the study was a prospective study. After signing the informed consent form, eligible patients were included. After collecting blood routine or arterial blood gas analysis, the remaining blood was centrifuged and the plasma was frozen at -80°C for subsequent detection of nitric oxide.
The primary exposure variable was the administration of ulinastatin in patients with sepsis. Demographic data, including age and gender, were collected at ICU admission. Additional exposure variables included blood biochemical markers and infection-related indicators. Clinical comorbidities were recorded based on established diagnoses documented in the medical record, including hypertension, coronary artery disease, atrial fibrillation, diabetes, respiratory diseases (chronic obstructive pulmonary disease, asthma, chronic bronchitis, and bronchiectasis), renal dysfunction, history of tumor, history of stroke, and liver cirrhosis.
The primary outcome was the occurrence of SAE within 3 days of enrollment. Secondary outcomes in the prospective cohort included the fasting blood glucose/ high density lipoprotein cholesterol (FBG/HDL-C), in-hospital mortality, 28-day survival rate, and 28-day survival time.

研究组 & 干预措施
Ulinastatin Group
Patients diagnosed with sepsis who received ulinastatin as part of routine clinical care. The use of ulinastatin was not assigned by study protocol but determined by treating physicians. Clinical outcomes, including the incidence of SAE, were assessed.
干预措施: ulinastatin (Drug)
结局指标
主要结局
The incidence of sepsis-associated encephalopathy (SAE)
时间窗: 3 days
Glasgow Coma Scale (GCS) score of less than 15 or the presence of delirium symptoms confirmed by the Confusion Assessment Method for the ICU (CAM-ICU)
次要结局
- Survival time(28 days)
- FBG/HDL-C ratio (fasting blood glucose to high-density lipoprotein cholesterol ratio)(3rd day)
- In-hospital mortality(From hospital admission until discharge or in-hospital death, whichever occurred first, assessed up to 90 days.)
