- 使用临床参数和固醇生物标志物,开发和评估COVID-19疾病严重性的预测模型.
主要方法:
- 在不同疾病阶段的164名住院COVID-19患者中比较了10种胆固醇生物合成中间体的度.
- 开发了机器学习模型,使用8个临床参数和一组固醇来预测疾病严重程度.
- 使用曲线下的面积 (AUC) 验证了模型性能,并将其与现有的临床风险得分 (如COVID-GRAM) 进行了比较.
主要成果:
- 在COVID-19患者中观察到齐莫斯特,24-脱罗拉托斯特,德斯莫斯特和齐莫斯坦水平的显著变化.
- 基于单独临床参数的机器学习模型在预测疾病严重程度方面取得了很好的准确性 (AUC = 0.96).
- 将固醇水平纳入模型进一步提高了与现有分数相比的预测性能.
结论:
- 这项研究是首次证明胆固醇生物合成途径与COVID-19严重程度之间的联系.
- 特定的固醇与COVID-19疾病严重程度有显著的关联,可以作为潜在的生物标志物.
