感染性休克是ICU常见的重症综合征,病情重,进展迅速,为机体对感染反应失调所致的危及生命的多器官功能障碍综合征[1]。尽管现代医学治疗手段已有明显进步,感染性休克病人死亡率仍然很高,在ICU病房中死亡率超过40%[2],准确评估病情对救治及改善病人预后具有重要意义。感染性休克发病及病情进展机制复杂,目前认为其中免疫状态、炎症机制在疾病的发生发展过程中起了至关重要的作用[3-4]。所以病人免疫、炎症反应及器官功能状态是反映病人病情严重程度以及指导治疗的重要指标。本研究通过检测CD4+与CD8+比值(CD4+/CD8+)、N末端脑钠肽前体(NT-proBNP)及白细胞介素6(IL-6),分别从免疫状态、炎症反应、心功能等方面综合阐述其与感染性休克病人疾病严重程度及预后的关系。现作报道。

Abstract:ObjectiveTo investigate the value of the lymphocyte CD4+/CD8+ ratio, N-terminal brain natriuretic peptide precursor(NT-probNP) and interleukin 6(IL-6) in evaluating the prognosis of patients with septic shock. MethodsSeventy-seven patients with septic shock were selected for prospective study, and the CD4+/CD8+ ratio, NT-probNP, IL-6 and Maximun lactate (Lac) levels in all cases were detected in the first 24 h after septic shock.The gender, age, acute physiology and chronic health status scoring system Ⅱ(APACHE Ⅱ) score, combined with underlying diseases and other data were recorded.The independent risk factors of death in septic shock patients were analyzed by logistic regression analysis, and the CD4+/CD8+ ratio, NT-probNP and IL-6 were analyzed by linear correlation regression with APACHE Ⅱ score.The receiver operating characteristic(ROC) curve was drawn to analyze the value of CD4+/CD8+ ratio, NT-probNP and IL-6 in the evaluation of prognosis of patients with septic shock. ResultsThe levels of NT-probNP and IL-6 in septic shock death group were significantly higher than those in survival group(P < 0.05), and the CD4+/CD8+ ratio in septic shock death group was significantly lower than that in survival group.The results of logistic regression analysis showed that the age, APACHE Ⅱ score, underlying disease, Lac, NT-probNP and IL-6 were the independent risk factors of death in patients with septic shock, and the CD4+/CD8+ ratio was a protective factor.The IL-6 and NT-probNP had a good correlation with APACHE Ⅱ(P < 0.01), while the CD4+/CD8+ ratio had not significant correlation with APACHE Ⅱ(P>0.05).The ROC curve showed that the predictive efficacy of serum NT-probNP, IL-6 and blood CD4+/CD8+ ratio on the death of septic shock patients on day 1 were 0.793, 0.678 and 0.708, respectively(P < 0.05).The area under ROC curve was 0.840(P < 0.05). ConclusionsThe CD4+/CD8+ ratio, NT-proBNP and IL-6 are significantly correlated with the severity and prognosis of septic shock patients.The combination of these three factors has excellent predictive value for the prognosis of septic shock patients. -
