这项研究确定了用于结核病 (TB) 查的宿主血液蛋白生物标志物. C-反应蛋白 (CRP) 显示出希望,特别是在艾滋病毒感染者中,但需要更多的研究.
科学领域:
- 医学诊断 医学诊断 医学诊断
- 生物标志物发现发现
- 传染病研究 传染病研究
背景情况:
- 结核病 (TB) 诊断需要改进的非唾液测试,以满足世界卫生组织 (WHO) 针对医疗点 (POC) 查的目标产品概况 (TPP).
- 目前的诊断缺口需要识别具有高灵敏度和特异性的宿主血液蛋白生物标志物.
研究的目的:
- 系统地审查和识别结核病 (TB) 的宿主血液蛋白生物标志物,这些生物标志物符合世卫组织TPP对POC查测试的标准.
- 使用元分析评估已识别的生物标志物的诊断准确性.
主要方法:
- 根据PRISMA指导方针进行了系统性审查,包括65项研究的数据提取和质量评估 (QUADAS-2),共1610名参与者.
- 对至少四项具有相似截止值的研究报告的生物标志物进行了元分析,评估了异质性.
- 评估了156种宿主蛋白质,重点是成人肺结核,肺外结核和儿科结核.
主要成果:
- 对于成年肺结核,C反应蛋白 (CRP),干扰素-诱导蛋白10 (IP-10),神经细胞粘附分子1 (NCAM-1) 和血清粉样蛋白A (SAA) 在高质量的研究中满足了TPP标准.
- 在10 mg/L的切割值中,CRP在10项研究中显示了86%的综合灵敏度和67%的特异性.
- 在艾滋病毒感染者中,CRP在六项研究中表现出93%的综合灵敏度和59%的特异性.
结论:
- 主体血液中的CRP,IP-10,NCAM-1和SAA等蛋白质显示出结核病查的潜在生物标志物,特别是HIV感染者的CRP.
- 尽管有前途的发现,但研究设计和生物标志物切线存在显著的异质性,限制了目前的适用性.
- 跨多种子组的前性研究中的标准化验证对于开发可靠的POC结核病诊断试验至关重要.

Pulmonary Tuberculosis V
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the...
Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
