概括
在住院COVID-19患者中,可溶性瘤发生性抑制剂2 (sST2) 和核细胞的较高水平预测了更长的住院时间. 高的sST2特别表明预后较差,恢复速度较慢,表明其作为治疗点的潜力.
科学领域:
- 生物标志物 生物标志物
- COVID-19的病理生理学
- 临床结果 临床结果
背景情况:
- 住院COVID-19患者表现出复杂的病理生理学,包括内皮病变,血栓炎症和纤维化.
- 预测COVID-19的临床结果对于患者管理和资源分配至关重要.
研究的目的:
- 研究住院COVID-19患者的基线生物标志物水平和临床结果之间的关联.
- 确定特定的生物标志物,预测出院时间和临床恶化.
主要方法:
- 从DisCoVeRy试验中对454名住院COVID-19患者的21个基线生物标志物的分析.
- 使用了根据临床严重程度,D-二次体和治疗方案进行调整的多变量模型.
- 使用确认队列 (SARCODO研究) 来验证可溶性瘤发生性抑制剂2 (sST2) 的发现.
主要成果:
- 瘤发生性2 (sST2) 溶性抑制剂和核细胞的基线水平升高与29日前出院的可能性降低有关.
- 较高的基线sST2水平与NEWS-2得分在第15天的改善较小相关.
- 在SARCODO队列中,高的sST2独立预测了更低的放电率和更好的模型性能 (AUC92%).
结论:
- 可溶性瘤性抑制剂2 (sST2) 是住院COVID-19患者不良临床结果的独立预测剂.
- sST2可能在COVID-19疾病进展中发挥重要作用.
- 对sST2的作用和治疗潜力的进一步研究是有必要的.

15.1K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Diagnosing acute coronary syndrome or ACS begins with a thorough patient history. Notable symptoms include central, crushing chest pain radiating to the left arm, neck, jaw, or back, along with shortness of breath, sweating (diaphoresis), nausea, vomiting, dizziness, and palpitations.It is crucial to note any history of cardiac illnesses and assess risk factors, including age, gender, smoking, hypertension, diabetes, hyperlipidemia, and a sedentary lifestyle.During physical examination, vital...
