SAP患者GLI与外周血各指标变化的临床意义

Clinical significance of changes in GLI and peripheral blood indicators in SAP patients

目的探究血糖不稳定指数(GLI)联合外周血CD4^(+)/CD8^(+)、中性粒细胞与淋巴细胞比值(NLR)、红细胞分布宽度(RDW)、中性粒细胞明胶酶相关脂质运载蛋白(NGAL)与卒中相关性肺炎(SAP)的发生、发展及预后的关系。方法550例急性脑梗死患者据发病7 d内SAP发生情况分为研究组(发生SAP)129例和对照组(未发生SAP)421例;测定GLI、外周血CD4^(+)/CD8^(+)、NLR、RDW、NGAL水平,对比研究组与对照组及不同病情、不同预后SAP患者上述指标差异,分析指标与SAP的发生、发展及预后的关系及指标对SAP预后的预测价值。结果研究组、中高危组、预后不良组GLI、NLR、RDW、NGAL水平分别高于相应的对照组、低危组、预后良好组,CD4^(+)/CD8^(+)水平分别低于相对应组(P<0.05)。多因素Logistic回归分析示,较高水平的GLI、NLR是急性脑梗死并发SAP的独立危险因素,较高水平的GLI、NLR、RDW、NGAL是SAP患者中高危病情的独立危险因素,较高水平的CD4^(+)/CD8^(+)是并发SAP、SAP患者中高危病情的保护因素(P<0.05);较高水平的GLI、NLR、RDW是SAP患者预后不良的独立危险因素(P<0.05)。受试者工作特征(ROC)曲线分析示,GLI、NLR、RDW联合诊断SAP预后不良的曲线下面积(AUC)优于GLI、RDW单一指标诊断。结论GLI、CD4^(+)/CD8^(+)、NLR水平变化是SAP发生的影响因素,GLI、CD4^(+)/CD8^(+)、NLR、RDW、NGAL是SAP患者病情严重程度的影响因素;GLI、NLR、RDW与SAP患者预后不良有关,三者在预测SAP患者预后方面具有一定预测效能,NLR的预测效能最高。

Objective To explore the relationship between glycemic instability index(GLI),peripheral blood CD4^(+)/CD8^(+),neutrophil-to-lymphocyte ratio(NLR),red blood cell distribution width(RDW),neutrophil gelatinase-associated lipocalin(NGAL),and the occurrence,condition and prognosis of stroke-associated pneumonia(SAP).Methods According to the occurrence of SAP within 7 d after onset,550 patients with acute cerebral infarction were divided into the study group(129 cases with SAP)and the control group(421 cases without SAP).GLI,peripheral blood CD4^(+)/CD8^(+),NLR,RDW and NGAL levels were measured.The differences in the above indicators were compared between the study group and the control group,as well as SAP patients with different conditions and prognoses.The relationship between above indicators and the occurrence,condition and prognosis of SAP was discussed.The prognostic values of each indicator and combination of indicators were analyzed.Results GLI,NLR,RDW and NGAL levels were higher in the study group,the medium to high risk group and the poor prognosis group than those in the control group,the low-risk group and the good prognosis group.CD4^(+)/CD8^(+)was lower than that in the corresponding group(P<0.05).Multivariate Logistic regression analysis showed that higher GLI and NLR were independent risk factors for acute cerebral infarction complicated with SAP,and higher GLI,NLR,RDW and NGAL were independent risk factors for the medium to high risk conditions in SAP patients,while higher levels of CD4^(+)/CD8^(+)were protective factor for high-risk diseases in patients with concurrent SAP and SAP(P<0.05).Higher GLI,NLR and RDW were independent risk factors for poor prognosis in patients with SAP(P<0.05).ROC curves indicated that the AUC of the combination of GLI,NLR and RDW for evaluating poor prognosis in patients with SAP was better than that of GLI or RDW.Conclusion Changes in GLI,CD4^(+)/CD8^(+)and NLR are influencing factors for the occurrence of SAP.GLI,CD4^(+)/CD8^(+),NLR,RDW and NGAL are influencing factors for the severity of SAP patients.GLI,NLR and RDW are associated with poor prognosis in SAP patients,and all three have certain predictive effective in predicting the prognosis of SAP patients,and NLR has the highest predictive efficacy.
