新的生物标志物CCL8和CXCL9在区分活跃结核病 (ATB) 和潜伏感染 (LTBI) 方面表现有前途. 这些化学物质可以改善结核病诊断,有助于区分疾病阶段,以便更好地管理患者.
科学领域:
- 免疫学 免疫学 免疫学
- 传染性疾病 传染性疾病
- 生物标志物发现发现
背景情况:
- 干扰素γ释放试验 (IGRA) 是结核病 (TB) 诊断的标准,但难以区分潜伏结核病感染 (LTBI) 和活跃结核病 (ATB).
- 对于有效的治疗策略,迫切需要可靠的生物标志物来区分LTBI和ATB.
研究的目的:
- 识别和验证能够区分LTBI和ATB病例的新型抗原特异性生物标志物.
- 评估化学因子在区分结核病感染状态中的诊断潜力.
主要方法:
- 招募了208名参与者 (健康对照,LTBI和ATB) 的队列.
- 在Luminex测试中,在发现队列中测量了40种化学基因,以确定潜在的生物标志物.
- 候选生物标志物在一个单独的验证队列中使用ELISA进行了验证.
主要成果:
- CCL8和CXCL9表现出显著的能力,在LTBI和ATB之间进行歧视.
- 对CCL8和CXCL9的综合分析产生了最高的诊断准确性 (AUC=0.929).
- 在鉴定ATB的验证队列中,CCL8显示出高灵敏度 (90.79%) 和特异性 (100.00%).
结论:
- 结核病特异性化学因子,特别是CCL8和CXCL9,显示出作为活性结核病的诊断生物标志物的潜力.
- 需要进一步的研究来证实CCL8在区分ATB和LTBI方面的有用性,特别是在细菌学上未经证实的病例中.

Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...
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.
