Prediction of the severity of COVID-19 at its onset is important for providing adequate and timely management to reduce mortality.
To study the prognostic value of damage parameters and cytokines as predictors of severity of COVID-19 using an extensive immunologic profiling and unbiased artificial intelligence methods.
Sixty hospitalized COVID-19 patients (30 moderate and 30 severe) and 17 healthy controls were included in the study. The damage indicators high mobility group box 1 (HMGB1), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), alanine aminotransferase (ALT), extensive biochemical analyses, a panel of 47 cytokines and chemokines were analyzed at weeks 1, 2 and 7 along with clinical complaints and CT scans of the lungs. Unbiased artificial intelligence (AI) methods (logistic regression and Support Vector Machine and Random Forest algorithms) were applied to investigate the contribution of each parameter to prediction of the severity of the disease.
On admission, the severely ill patients had significantly higher levels of LDH, IL-6, monokine induced by gamma interferon (MIG), D-dimer, fibrinogen, glucose than the patients with moderate disease. The levels of macrophage derived cytokine (MDC) were lower in severely ill patients. Based on artificial intelligence analysis, eight parameters (creatinine, glucose, monocyte number, fibrinogen, MDC, MIG, C-reactive protein (CRP) and IL-6 have been identified that could predict with an accuracy of 83-87% whether the patient will develop severe disease.
This study identifies the prognostic factors and provides a methodology for making prediction for COVID-19 patients based on widely accepted biomarkers that can be measured in most conventional clinical laboratories worldwide.
在疾病发作时预测 COVID-19 的严重程度对于提供充分和及时的治疗以降低死亡率非常重要。
使用广泛的免疫分析和无偏人工智能方法研究损伤参数和细胞因子作为 COVID-19 严重程度预测指标的预后价值。
研究纳入了 60 例住院 COVID-19 患者(30 例中度和 30 例重度)和 17 名健康对照者。在第 1、2 和 7 周,分析了损伤标志物高迁移率族蛋白 B1(HMGB1)、乳酸脱氢酶(LDH)、天门冬氨酸氨基转移酶(AST)、丙氨酸氨基转移酶(ALT)、广泛的生化分析、47 种细胞因子和趋化因子的面板以及肺部 CT 扫描,并结合临床症状。应用无偏人工智能(AI)方法(逻辑回归、支持向量机和随机森林算法)研究每个参数对疾病严重程度预测的贡献。
入院时,重症患者的 LDH、IL-6、γ干扰素诱导的单核细胞因子(MIG)、D-二聚体、纤维蛋白原、血糖水平明显高于中度疾病患者。重症患者的巨噬细胞来源细胞因子(MDC)水平较低。基于人工智能分析,确定了 8 个参数(肌酐、血糖、单核细胞数、纤维蛋白原、MDC、MIG、C 反应蛋白(CRP)和 IL-6),这些参数可以以 83%-87%的准确率预测患者是否会发展为重症。
本研究确定了预后因素,并提供了一种基于广泛认可的生物标志物的 COVID-19 患者预测方法,这些标志物可在全球大多数常规临床实验室进行测量。
