结核病 (TB) 的C-反应蛋白 (CRP) 测试在一项多国研究中没有达到准确性目标. 性能因地区和患者因素而异,表明作为通用结核病查工具的效用有限.
科学领域:
- 全球健康 全球健康
- 传染性疾病 传染性疾病
- 诊断的准确性 诊断的准确性
背景情况:
- 推使用C反应蛋白 (CRP) 进行艾滋病毒感染者的结核病 (TB) 查.
- 它在非艾滋病毒患者群体和不同地理环境中的诊断性能在很大程度上是未知的.
研究的目的:
- 评估CRP是否符合结核病查的最低准确性目标 (灵敏度≥90%,特异性≥70%).
- 评估不同国家,性别和艾滋病毒/糖尿病状况的CRP表现.
主要方法:
- 一项涉及非洲和亚洲结核病流行地区长期咳的2904名门诊患者的多国研究.
- 进行了临床CRP检测,艾滋病毒/糖尿病查和唾液分析 (Xpert MTB/RIF Ultra,培养).
- 多变量接收器操作曲线回归确定了影响CRP性能的因素.
主要成果:
- 整体CRP敏感度为84%,特异性为61%,低于目标值.
- 性能因国家而异:非洲 (≥91%) 与亚洲 (64-82%) 的敏感性更高.
- 在男性中,敏感性更高;在艾滋病毒感染者中,特异性更低.
结论:
- 目前,C-反应蛋白 (CRP) 测试尚未达到广泛的结核病查所需的准确性.
- 地理变化和人口因素,可能与真菌细菌负载有关,影响CRP的诊断效用.
- 需要进行进一步的研究,以了解和潜在地改善不同结核病受影响人群的CRP性能.
