摘要:

目的 探讨中性粒细胞/淋巴细胞比值(NLR)、C反应蛋白(CRP)、降钙素原(PCT)、D-二聚体(DD)、氨基末端B型钠尿肽原(NT-proBNP)对重症新型冠状病毒肺炎(COVID-19)的诊断价值。方法 选取105例COVID-19患者,根据COVID-19诊断标准将患者分成轻症组(83例)、重症组(22例)。以50名体检健康者作为健康对照组。比较3组之间的年龄、性别及白细胞(WBC)计数、中性粒细胞绝对数(NEUT#)、淋巴细胞绝对数(LYMPH#)、NLR、CRP、PCT、DD、NT-proBNP水平。结果 与健康对照组相比,轻症组、重症组年龄大,且以男性为主。与轻症组相比,重症组年龄更大(P<0.05)。与轻症组相比,重症组WBC计数、NEUT#、NLR、CRP、PCT、DD、NT-proBNP水平明显增高(P<0.05),LYMPH#水平明显降低(P<0.05);与健康对照组相比,轻症组NLR、CRP、DD、NT-proBNP水平较高(P<0.05),WBC计数、LYMPH#水平较低(P<0.05)。5种诊断指标中NT-proBNP对重症COVID-19的诊断价值较高,联合检测优于单项检测。NT-proBNP诊断COVID-19的敏感性为95.45%,特异性为93.98%,阳性预测值80.77%、阴性预测值98.73%。结论 NT-proBNP对重症COVID-19的诊断价值较高,当与NLR、CRP、PCT、DD时联合检测时对重症COVID-19的诊断价值更高。

Abstract:

Objective To investigate the diagnostic roles of neutrophil/lymphocyte ratio(NLR),C-reactive protein(CRP),procalcitonin(PCT),D-dimer(DD) and amino terminal B-type natriuretic peptide(NT-proBNP)in severe corona virus disease 2019(COVID-19). Methods A total of 105 COVID-19 patients were enrolled. According to COVID-19 diagnostic criteria,these patients were classified into general group(83 cases)and severe group(22 cases). Fifty healthy subjects were enrolled as control group. The age,sex,white blood cell(WBC)count,the absolute value of neutrophil(NEUT#),the absolute value of lymphocyte(LYMPH#),NLR,CRP,PCT,DD and NT-proBNP of the 3 groups were compared. Results The patients in general and severe groups were older than healthy subjectsand were predominantly male. The patients in severe group were significantly older than those in general group(P<0.05). Compared with general group,WBC count,NEUT#,NLR,CRP,PCT,DD and NT-proBNP were higher in severe group,and LYMPH# was lower(P<0.05). General group had higher levels of NLR,CRP,DD and NT-proBNP than healthy control group,while WBC count and LYMPH# were on the contrary(P<0.05). NT-proBNP had the highest diagnostic value for severe COVID-19,and the combined determination had better performance than single determination. The sensitivity,specificity,positive predictive value and negative predictive value of NT-proBNP were 95.45%,93.98%,80.77% and 98.73%,respectively. Conclusion NT-proBNP is of high diagnostic value for severe COVID-19. The combined determination of NT-proBNP,NLR,CRP,PCT and DD has higher value in the diagnosis of severe COVID-19.
