在尼日利亚监狱使用GeneXpert测试积极寻找病例,显著增加了结核病 (TB) 检测率. 这种系统的方法发现了比被动方法更多的结核病例,突出了结核病对惩戒设施公共卫生的重要性.
科学领域:
- 公共卫生 公共卫生
- 传染病流行病学 传染病流行病学
- 临床诊断 临床诊断 临床诊断
背景情况:
- 结核病 (TB) 在尼日利亚惩戒设施中构成重大健康威胁,其患病率高达普通人口的十倍.
- 传统的被动结核病例检测方法往往无法识别无症状感染,需要改进查策略.
研究的目的:
- 评估一个系统的活跃病例发现 (ACF) 策略,使用基于症状的查和GeneXpert MTB/RIF测试在尼日利亚两个惩戒设施.
- 为了确定ACF在提高结核病诊断的有效性,在一个高患病率的校正设置.
主要方法:
- 在2021年4月至9月期间,共有2,244名囚犯接受了结核病症状查.
- 假定结核病例为GeneXpert分析提供了唾液,干预措施包括外展查,细胞对细胞搜索和接触者追踪.
- 分析了数据,以计算每10万囚犯的检测率和整体阳性收益率.
主要成果:
- 该研究确定了45例确诊的结核病例,估计患病率为0.5% (每10万囚犯中有489人),是全国平均水平的两倍多.
- 假定囚犯中的整体结核病阳性率为7%,拉各斯州和奥贡州的点患病率分别为500和458/100,000.
- 所有检测到的结核病例都对利法素敏感,没有发现耐药菌株.
结论:
- 基于症状的GeneXpert查是一种有效的方法,用于在惩戒设施中积极寻找病例,大大提高了被动检测率.
- 系统的ACF,包括普遍的入口查和定期的全设施检查,对于高风险环境中早期结核病诊断和治疗启动至关重要.
- 建议包括制度化常规ACF,整合快速分子测试,并考虑数字放射学,以加强结核病控制在惩戒设置.
