摘要:

目的 探讨 CD4+T 细胞计数及单核细胞人类白细胞抗原⁃DR 表达率在预测老年脓毒症患者 预后的价值。方法 109 例老年脓毒症患者,分为死亡组(33 例)、存活组(76 例),比较两组免疫功能指 标,如 CD3+T 细胞计数、CD4+T 细胞计数、CD4+ /CD8+T 细胞比值及单核细胞人白细胞 DR 抗原表达率的差异并进行影响 90 d 内死亡因素的 logistic 回归及 ROC 曲线分析潜在指标预测 90 d 内死亡结局的准确性。 结果 死亡组治疗第 1 天及第 7 CD3+T 细胞计数、CD4+T 细胞计数、单核细胞人白细胞 DR 抗原表达率均 显著低于存活组(P < 0.05)。入院后第 1 CD4+T 细胞计数及单核细胞人类白细胞抗原⁃DR 表达率并不是 脓毒症 90 d 死亡的独立危险因素,而治疗第 7 天时 CD4+T 细胞计数及单核细胞人类白细胞抗原⁃DR 表达 率是 90 d 死亡的独立危险因素并能够有效预测 90 d 死亡风险。CD4+T 细胞计数(AUC = 0.847,95%CI 0.774 ~ 0.920)的预测最佳截断值为 197.0 cells/μL,单核细胞人类白细胞抗原⁃DR 表达率(AUC = 0.898 95%CI:0.829 ~ 0.966)预测最佳截断值为 40.5%。单核细胞人类白细胞抗原⁃DR 表达率的准确性高于 CD4+ T 细胞计数,CD4 +T 细胞计数联合单核细胞人类白细胞抗原⁃DR 表达率(AUC = 0.928,95%CI:0.883 ~ 0.974)预测特异性高于单个参数。结论 老年脓毒症患者治疗第 7 天时 CD4+T 细胞计数及单核细胞人类 白细胞抗原⁃DR 表达率是 90 d 死亡的独立危险因素,两者均为 90 d 死亡的有效预测指标,CD4+T 细胞计数 及单核细胞人类白细胞抗原⁃DR 表达率可以作为改善脓毒症预后的早期干预靶标。

Abstract:

Objective To explore the value of CD4+ T cell count and the expression rate of mHLA⁃DR in predicting the prognosis of elderly patients with sepsis. Methods One hundred and nine elderly patients with sepsis were divided into death group(= 33)and survival group(= 76). The change of immunologic function indexes such as CD3+ T cell count and CD4+ T cell count and the ratio of CD4+ /CD8+ T cell count and the expression rate of monocyte HLA ⁃DR were compared and analyzed. Multivariate logistic regression was used to analyze the influencing factors affecting the 90⁃day mortality and ROC curve to analyze the potential indicators in predicting the accuracy of the 90⁃day mortality. Results CD3+ T cell count,CD4+ T cell count and the expression rate of mono⁃ cyte HLA⁃DR in death group at the 1st and the 7th day of treatment were significantly lower than those in survival group(< 0.05). CD4+ T cell count and the expression rate of monocyte HLA⁃DR at the 1st day of treatment were not independent risk factors for the 90⁃day mortality in sepsis. CD4+ T cell count(AUC = 0.847,95% CI:0.774 ~ 0.920)and the expression rate of monocyte HLA ⁃DR(AUC = 0.898,95% CI:0.829 ~ 0.966)at the 7th day of treatment were independent risk factors for the 90⁃day mortality and they effectively predicted the risk of death. The predicted best cut⁃off value for CD4+ T cell count was 197.0 cells/μL and that for the expression rates of monocyte HLA⁃DR 40.5%. The accuracy of the expression rate of monocyte HLA⁃DR in predicting the 90⁃day mortality was higher than that of CD4 + T cell count. The prediction specificity of the expression rate of monocyte HLA ⁃DR combined with CD4 + T cell count(AUC 0.928,95%CI 0.883 ~ 0.974)was higher than that of the single parameter. Conclusion The expression rate of monocyte HLA⁃DR and CD4+ T cell count on the 7th day of treatment areindependent risk factors and effective predictors of the 90⁃day mortality in elderly patients with sepsis and they can be targets for early intervention to improve the prognosis of sepsis.
