摘要 隐球菌病和肺结核是慢性阻塞性肺疾病患者的主要死亡原因 撒哈拉以南地区的艾滋病毒/艾滋病，包括开始抗逆转录病毒疗法(ART)的患者。 尽管有越来越多的努力促进患者早期诊断结核病 启动ART，只有几个项目将注意力集中在早期 诊断和治疗隐球菌病以减少隐球菌病的发生 发病率和死亡率。 通过对患者进行有效的筛查，可以实现对隐球菌病的早期诊断 在抗逆转录病毒治疗开始之前，有低的CD4计数(&lt；100cell/mm3)。最近的 开发侧向流动法(LFA)，这是一种低成本的护理点测试，不 需要昂贵的设备或高技能的实验室技术人员提供 在资源有限的情况下提供早期诊断隐球菌病的机会。 我们建议在以下地点评估隐球菌病筛查计划的实施情况 津巴布韦哈拉雷的一个大型公共艾滋病毒/抗逆转录病毒治疗中心。主要目标是 通过减少与启动抗逆转录病毒治疗相关的发病率和死亡率 隐球菌病的发病率和死亡率。我们将测试LFA的性能 对照金标准(隐球菌抗原乳胶凝集试验、血液和脑脊液 培养)，并测定其在全血(指棒)和 尿液。我们还建议开发一种脑膜炎风险评分，可以远程使用 在LFA检测呈阳性的患者中识别哪些患者病情最严重的设施 隐球菌性脑膜炎的风险，需要转移到资源更充足的脊椎设施 水龙头和静脉抗真菌治疗。 通过使用低成本成功实施这一筛查计划 干预措施有可能减少ART治疗中隐球菌病的发生率 撒哈拉以南非洲的项目。

ABSTRACT Cryptococcosis and tuberculosis are the leading causes of death in patients with HIV/AIDS in sub-Saharan, including patients initiating antiretroviral therapy (ART). Although there are increasing efforts to facilitate early diagnosis of TB in patients initiating ART, there are only a few programs that have focused attention on the early diagnosis and treatment of cryptococcal disease to decrease cryptococcosis associated morbidity and mortality. Early diagnosis of cryptococcal disease can be achieved by effectively screening patients with low CD4 counts (<100cells/mm3) prior to the initiation of ART. The recent development of the lateral flow assay (LFA), a low cost point of care test that does not require expensive equipment or a highly skilled laboratory technician provides an opportunity for early diagnosis of cryptococcal disease in resource limited settings. We propose to evaluate the implementation of a screening program for cryptococcosis at a large public HIV/ART treatment centre in Harare, Zimbabwe. The primary objective is to decrease morbidity and mortality associated with the initiation of ART by decreasing morbidity and mortality due to cryptococcosis. We will test the performance of the LFA against gold standards (cryptococcal antigen latex agglutination assays, blood and CSF cultures) and determine its sensitivity and specificity in whole blood (finger stick) and urine. We also propose to develop a meningitis risk score that can be used by remote facilities to identify among patients with a positive LFA test which patients are at greatest risk of cryptococcal meningitis and require transfer to better resourced facilities for spinal taps and intravenous antifungal therapy. The successful implementation of this screening program through the use of low cost interventions has the potential to decrease incident cryptococcosis in ART treatment programs in sub-Saharan Africa.
