摘要:

目的 探讨早期实验室指标在新型冠状病毒肺炎(COVID-19)病情严重度判断中的作用。方法 回顾性分析85例COVID-19患者入院时外周血各项实验室检查结果,包括血常规、肝功能、肾功能、凝血功能、白介素-6(IL-6)、铁蛋白、C反应蛋白(CRP)、红细胞沉降率(ESR)、降钙素原(PCT)、肌红蛋白、肌钙蛋白、淀粉样蛋白A,并对普通型和重症型患者各项数据进行分析比较。结果 重症型COVID-19患者白细胞(WBC)计数、中性粒细胞绝对数(NEUT#)、中性粒细胞/淋巴细胞比值(NLR)、乳酸脱氢酶(LDH)、CRP、D-二聚体(DD)、铁蛋白和肌酐较普通型患者明显升高(P<0.05)。早期WBC计数、NEUT#、NLR、LDH、肌红蛋白、CRP、铁蛋白升高是COVID-19患者重症化风险预测指标。NLR作为独立风险因子,临界值为5.61时,诊断重症化的敏感性为68.75%,特异性为78.38%。结论 COVID-19患者早期WBC计数、NEUT#、NLR、LDH、肌红蛋白、CRP和铁蛋白水平明显升高,提示存在重症化风险,其中NLR是COVID-19重症化的独立预警指标。

Abstract:

Objective To evaluate the predictive role of early laboratory indicators in the severity of corona virus disease 2019(COVID-19). Methods Retrospective analysis was used to analyze the laboratory results in 85 patients with COVID-19 at the time of admission,and the results included blood routine test,liver function,kidney function,blood coagulation function,interleukin 6(IL-6),ferritin,C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),procalcitonin(PCT),myoglobin,troponin and amyloid A. Results In severe group,the levels of white blood cell(WBC) count,the absolute value of neutrophil(NEUT#),neutrophil-lymphocyte ratio(NLR),lactate dehydrogenase(LDH),CRP,D-dimer(DD),ferritin and creatinine were higher than those in mild group(P<0.05). WBC count,NEUT#,NLR,LDH,myoglobin,CRP and ferritin were predictive risk factors of COVID-19. NLR was an independent predictor for the severity of COVID-19. When the cut-off value of NLR was 5.61,the sensitivity and specificity were 68.75% and 78.38%,respectively. Conclusions The increasing of WBC count,NEUT#,NLR,LDH,myoglobin,CRP and ferritin suggests the risk of severity,and NLR is an independent prediction for the severity of COVID-19.
