摘要:

目的 探讨老年脓毒症相关性脑病(SAE)患者血清神经纤维丝轻链(NFL)、神经球蛋白(NGB)的动态变化及其诊断价值。方法 纳入128例老年脓毒症患者并根据是否发生SAE分为SAE组(53例)和非SAE组(75例)。收集患者临床资料,采用酶联免疫吸附试验检测患者不同时间点(确诊后0~6 h、24 h、48 h)血清NFL、NGB水平。通过多因素Logistic回归分析0~6 h血清NFL、NGB水平与SAE的关系,并据此构建概率风险模型。受试者工作特征(ROC)曲线分析NFL、NGB水平及序贯器官衰竭评估(SOFA)、急性生理和慢性健康评估Ⅱ(APACHEⅡ)评分对SAE的诊断价值。结果 SAE组0~6 h、24 h、48 h血清NFL、NGB水平均高于非SAE组(P<0.05)。多因素Logistic回归分析显示,0~6 h血清NFL、NGB及SOFA评分、APACHEⅡ评分升高为SAE的独立危险因素(P<0.05)。ROC曲线分析显示,0~6 h血清NFL水平、NGB水平、SOFA评分、APACHEⅡ评分单独及四者联合诊断SAE的ROC曲线下面积(AUC)分别为0.723(95%CI:0.695~0.854)、0.769(95%CI:0.607~0.836)、0.677(95%CI:0.568~0.774)、0.700(95%CI:0.588~0.787)、0.894(95%CI:0.805~0.952),四因子联合应用优于各自单独诊断价值(P<0.05)。结论 老年脓毒症患者0~6 h血清NFL、NGB与相关评分联合对SAE具有较高的诊断价值。

Abstract:

Objective To investigate the dynamic changes of serum neurofilament light chain (NFL) and neuroglobin (NGB) in elderly patients with sepsis-associated encephalopathy (SAE) and their diagnostic value. Methods A total of 128 elderly sepsis patients were divided into the SAE group (53 cases) and the non-SAE group (75 cases) based on the occurrence of SAE. Clinical data were collected. Serum NFL and NGB levels were measured using enzyme-linked immunosorbent assay at different time points (0-6 h, 24 h and 48 h after diagnosis). Multivariate Logistic regression was used to analyze the relationship between serum NFL and NGB levels at 0-6 h and SAE, and a probability risk model was constructed accordingly. Receiver operating characteristic (ROC) curve analysis was performed to evaluate the auxiliary diagnostic value of NFL, NGB levels, sequential organ failure assessment (SOFA) score and acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score for SAE. Results Serum NFL and NGB levels at 0-6 h, 24 h and 48 h were higher in the SAE group compared to those of the non-SAE group (P<0.05). Multivariate Logistic regression analysis showed that elevated serum NFL and NGB levels at 0-6 h, as well as higher SOFA and APACHE Ⅱ scores, were independent risk factors for SAE (P<0.05). ROC curve analysis showed that the area under the curve (AUC) for diagnosing SAE was 0.723 (95%CI: 0.695-0.854) for serum NFL at 0-6 h, 0.769 (95%CI: 0.607-0.836) for NGB at 0-6 h, 0.677 (95%CI: 0.568-0.774) for SOFA score, 0.700 (95%CI: 0.588-0.787) for APACHE Ⅱ score, and 0.894 (95%CI: 0.805-0.952) for the combination of all four factors. The combined application of the four factors was superior to their individual diagnostic values (P<0.05). Conclusion The combination of serum NFL and NGB and related scores within 0 to 6 hours has relatively high diagnostic value for SAE in elderly sepsis patients.
