摘要:

目的 探讨血清淀粉样蛋白A(SAA)联合血常规、C反应蛋白(CRP)检测在新型冠状病毒肺炎(COVID-19)诊断中的价值。方法 选取襄阳市中心医院30例COVID-19住院患者(COVID-19组),以33名体检健康者作为对照组,收集并分析所有研究对象的血常规、CRP、SAA检测数据以及临床资料。结果 与对照组比较,COVID-19组体温、中性粒细胞百分比(NEUT%)、CRP、SAA显著升高,淋巴细胞百分比(LYMPH%)显著降低(P<0.01),但白细胞(WBC)计数差异无统计学意义(P>0.05)。COVID-19组5个血液学指标中SAA的阳性率最高(93.3%)。受试者工作特征(ROC)曲线分析结果显示,SAA诊断COVID-19的曲线下面积(AUC)为0.994,最佳临界值为6.43 mg/L,敏感性和特异性分别为100%和91.9%。不同电子计算机断层扫描(CT)分期患者比较,SAA的差异有统计学意义(P<0.01),SAA判断CT分期的AUC为0.851,敏感性和特异性分别为82.4%和76.9%。结论 血液学指标,尤其是SAA,可快速、准确地辅助诊断COVID-19,为临床及时诊治提供参考。

Abstract:

Objective To investigate the roles of serum amyloid A(SAA)combined determination with C-reactive protein(CRP) and blood routine test in the diagnosis of corona virus disease 2019(COVID-19). Methods Totally,30 patients with COVID-19 in Xiangyang Central Hospital were enrolled as COVID-19 group,and 33 healthy subjects were enrolled as control group. The results of blood routine test and CRP and SAA determinations and their clinical data were collected and analyzed between the 2 groups. Results Compared with control group,body temperature,the percentage of neutrophil(NEUT%),CRP and SAA in COVID-19 group were increased,and the percentage of lymphocyte(LYMPH%) was decreased(P<0.01),but white blood cell(WBC) count had no statistical significance(P>0.05). The positive rate of SAA in the diagnosis of COVID-19 was 93.3%. When the opitmal cut-off value of SAA was 6.43 mg/L,the sensitivity was 100%,and the specificity was 91.9%. The area under receiver operating characteristic(ROC) curve(AUC) was 0.994. The AUC,sensitivity and specificity of SAA for different computed tomography(CT) stages were 0.851,82.4% and 76.9%,respectively,and SAA in different CT stages had statistical significance(P<0.01). Conclusions Hematological indexes,especially SAA,can diagnose COVID-19 rapidly and accurately,which can provide a reference for clinical treatment.
