The US President's Emergency Plan for AIDS Relief (PEPFAR) was launched to increase access to antiretroviral treatment (ART) among people living with HIV (PLHIV) and to prevent new HIV infections globally. As new infections have decreased in many PEPFAR-supported countries, PEPFAR is increasingly focusing on understanding and decreasing mortality among PLHIV, specifically by addressing advanced HIV disease (AHD) and its attendant opportunistic infections (OIs). Several developments in identifying AHD, in preventing, diagnosing, and treating selected OIs, and in PEPFAR's support for mortality surveillance make this an opportune moment for PEPFAR to address HIV-related mortality.
AHD upon diagnosis or re-engagement in HIV care is not uncommon, and it substantially increases risk of death from OIs. The World Health Organization provides evidence-based guidelines for a package of interventions for preventing, diagnosing, and treating common OIs, including tuberculosis (TB), cryptococcal meningitis, and severe bacterial infections. PEPFAR facilitates implementation of these guidelines. To identify PLHIV with low CD4, PEPFAR plans to support expanded access to CD4 testing, including a point-of-care assay that differentiates CD4 cell count as a binary of greater than or less than 200 cells/µL. To prevent AHD-related mortality, PEPFAR supports rapid ART initiation with integrase inhibitor-based regimens and implementation and documentation of TB preventive treatment. To diagnose selected OIs, PEPFAR is implementing urine lateral flow lipoarabinomannan use to identify TB among PLHIV who have a CD4 cell count < 200 cells/µL. To treat selected OIs, PEPFAR has focused on improving patient-centered care in TB/HIV co-infection services and scaling up implementation of new drug regimens for cryptococcal meningitis. To better understand mortality, PEPFAR has introduced an indicator, TX_ML, to routinely and systematically categorize outcomes, including deaths, among PLHIV on ART.
PEPFAR is increasing its efforts to identify AHD; to prevent, diagnose, and treat OIs; and to track mortality in its programs. These ongoing efforts, done in collaboration with other stakeholders, seek to decrease mortality among PLHIV.
美国总统艾滋病紧急救援计划(PEPFAR)旨在增加艾滋病毒感染者(PLHIV)获得抗逆转录病毒治疗(ART)的机会,并在全球预防新的艾滋病毒感染。随着许多受PEPFAR支持的国家新感染病例减少,PEPFAR越来越注重了解并降低PLHIV的死亡率,特别是通过应对晚期艾滋病毒疾病(AHD)及其随之而来的机会性感染(OIs)。在识别AHD、预防、诊断和治疗特定OIs以及PEPFAR对死亡率监测的支持方面的多项进展,使现在成为PEPFAR应对艾滋病毒相关死亡率的适当时机。
确诊或重新接受艾滋病毒治疗时出现AHD并不罕见,这会大幅增加因OIs导致死亡的风险。世界卫生组织为预防、诊断和治疗常见OIs(包括结核病(TB)、隐球菌性脑膜炎和严重细菌感染)的一系列干预措施提供了循证指南。PEPFAR促进这些指南的实施。为了识别CD4水平低的PLHIV,PEPFAR计划支持扩大CD4检测的可及性,包括一种即时检测方法,该方法可将CD4细胞计数区分为大于或小于200个细胞/微升的二元结果。为预防与AHD相关的死亡率,PEPFAR支持使用基于整合酶抑制剂的方案快速启动ART,并实施和记录结核病预防性治疗。为诊断特定的OIs,PEPFAR正在实施使用尿液侧向流动脂阿拉伯甘露聚糖检测法,以在CD4细胞计数<200个细胞/微升的PLHIV中识别结核病。为治疗特定的OIs,PEPFAR专注于改善结核病/艾滋病毒合并感染服务中以患者为中心的护理,并扩大隐球菌性脑膜炎新药方案的实施。为了更好地了解死亡率,PEPFAR引入了一个指标TX_ML,以便对接受ART的PLHIV的结局(包括死亡)进行常规和系统的分类。
PEPFAR正在加大力度识别AHD;预防、诊断和治疗OIs;并在其项目中跟踪死亡率。这些与其他利益相关者合作开展的持续努力旨在降低PLHIV的死亡率。
