BACKGROUND
Hematological indices can predict disease severity, progression, and death in patients with coronavirus disease-19 (COVID-19).
OBJECTIVES
To study the predictive value of the dynamic changes (first 48 h after ICU admission) of the following ratios: neutrophil-to-lymphocyte (NLR), platelet-to-lymphocyte (PLR), monocyte-to-lymphocyte (MLR), systemic inflammation index (SII), and derived neutrophil-to-lymphocyte (dNLR) for invasive mechanical ventilation (IMV) need and death in critically ill COVID-19 patients.
METHODS
Observational, retrospective, and multicentric analysis on 272 patients with severe or critical COVID-19 from two tertiary centers. Hematological indices were adjusted for confounders through multivariate analysis using Cox regression.
RESULTS
Patients comprised 186 males and 86 females with no difference across groups ( > 0.05). ΔNLR > 2 had the best independent predictive value for IMV need (HR = 5.05 (95% CI, 3.06-8.33, < 0.0001)), followed by ΔSII > 340 (HR = 3.56, 95% CI 2.21-5.74, < 0.0001) and ΔdNLR > 1 (HR = 2.61, 95% CI 1.7-4.01, < 0.0001). Death was also best predicted by an NLR > 11 (HR = 2.25, 95% CI: 1.31-3.86, = 0.003) followed by dNLR > 6.93 (HR = 1.89, 95% CI: 1.2-2.98, = 0.005) and SII > 3700 (HR = 1.68, 95% CI: 1.13-2.49, = 0.01).
CONCLUSIONS
Dynamic changes of NLR, SII, and dNLR independently predict IMV need and death in critically ill COVID-19 patients.
背景
血液学指标可预测冠状病毒病19（COVID-19）患者的疾病严重程度、进展及死亡情况。
目的
研究以下比值（入住重症监护病房后最初48小时内）的动态变化：中性粒细胞与淋巴细胞比值（NLR）、血小板与淋巴细胞比值（PLR）、单核细胞与淋巴细胞比值（MLR）、全身炎症指数（SII）以及衍生中性粒细胞与淋巴细胞比值（dNLR）对重症COVID-19患者有创机械通气（IMV）需求及死亡的预测价值。
方法
对来自两个三级中心的272例重症或危重症COVID-19患者进行观察性、回顾性多中心分析。通过使用Cox回归的多变量分析对血液学指标的混杂因素进行校正。
结果
患者包括186例男性和86例女性，各组间无差异（>0.05）。ΔNLR>2对IMV需求具有最佳的独立预测价值（HR = 5.05（95%CI，3.06 - 8.33，<0.0001）），其次是ΔSII>340（HR = 3.56，95%CI 2.21 - 5.74，<0.0001）和ΔdNLR>1（HR = 2.61，95%CI 1.7 - 4.01，<0.0001）。NLR>11对死亡的预测也最佳（HR = 2.25，95%CI：1.31 - 3.86，=0.003），其次是dNLR>6.93（HR = 1.89，95%CI：1.2 - 2.98，=0.005）和SII>3700（HR = 1.68，95%CI：1.13 - 2.49，=0.01）。
结论
NLR、SII和dNLR的动态变化可独立预测重症COVID-19患者的IMV需求及死亡情况。
