To investigate the course of biomarkers on admission and follow-up in order to identify early predictors for poor outcome in COVID-19 patients.
In this study, 132 COVID-19 patients were classified as good outcome (n=62) and poor outcome (n=70) groups. Laboratory parameters were evaluated on admission and within 5-7 days after hospitalization.
Baseline levels of neutrophil-lymphocyte ratio, CRP, procalcitonin, ferritin, D-dimer and LDH were higher (<0.01); lymphocyte count was lower in the poor outcome patients. During follow-up there was a larger decrease in lymphocyte count and more prominent increases in other biomarkers (<0.001). In ROC analysis, the AUCs strongly indicated the poor outcome on days 5-7 of the hospitalization.
This study suggests that the follow-up measurements of the biomarkers better predict the poor outcome in COVID-19 pneumonia.
研究入院时及随访期间生物标志物的变化过程，以确定新冠病毒疾病（COVID-19）患者不良预后的早期预测指标。
在本研究中，132例COVID-19患者被分为预后良好组（n = 62）和预后不良组（n = 70）。在入院时及住院后5 - 7天评估实验室参数。
预后不良患者的中性粒细胞与淋巴细胞比值、CRP、降钙素原、铁蛋白、D - 二聚体和乳酸脱氢酶的基线水平较高（<0.01）；淋巴细胞计数较低。在随访期间，淋巴细胞计数下降幅度更大，其他生物标志物升高更显著（<0.001）。在ROC分析中，曲线下面积（AUC）强烈表明在住院第5 - 7天时预后不良。
本研究表明，对生物标志物进行随访测量能更好地预测COVID-19肺炎的不良预后。
