In 2018, WHO issued guidelines for the diagnosis, prevention, and management of HIV-related cryptococcal disease. Two strategies are recommended to reduce the high mortality associated with HIV-related cryptococcal meningitis in low-income and middle-income countries (LMICs): optimised combination therapies for confirmed meningitis cases and cryptococcal antigen screening programmes for ambulatory people living with HIV who access care. WHO's preferred therapy for the treatment of HIV-related cryptococcal meningitis in LMICs is 1 week of amphotericin B plus flucytosine, and the alternative therapy is 2 weeks of fluconazole plus flucytosine. In the ACTA trial, 1-week (short course) amphotericin B plus flucytosine resulted in a 10-week mortality of 24% (95% CI -16 to 32) and 2 weeks of fluconazole and flucytosine resulted in a 10-week mortality of 35% (95% CI -29 to 41). However, with widely used fluconazole monotherapy, mortality because of HIV-related cryptococcal meningitis is approximately 70% in many African LMIC settings. Therefore, the potential to transform the management of HIV-related cryptococcal meningitis in resource-limited settings is substantial. Sustainable access to essential medicines, including flucytosine and amphotericin B, in LMICs is paramount and the focus of this Personal View.
2018 年,世卫组织发布了与 HIV 相关隐球菌病的诊断、预防和管理指南。为了降低低收入和中等收入国家(LMICs)中与 HIV 相关隐球菌性脑膜炎相关的高死亡率,推荐了两种策略:对确诊的脑膜炎病例采用优化联合疗法,对接受治疗的门诊 HIV 感染者采用隐球菌抗原筛查方案。世卫组织在 LMICs 中治疗 HIV 相关隐球菌性脑膜炎的首选疗法是 1 周两性霉素 B 加氟胞嘧啶,替代疗法是 2 周氟康唑加氟胞嘧啶。在 ACTA 试验中,1 周(短疗程)两性霉素 B 加氟胞嘧啶导致 10 周死亡率为 24%(95%CI -16 至 32),2 周氟康唑和氟胞嘧啶导致 10 周死亡率为 35%(95%CI -29 至 41)。然而,在许多非洲 LMIC 环境中,由于广泛使用氟康唑单药治疗,HIV 相关隐球菌性脑膜炎的死亡率约为 70%。因此,在资源有限的情况下,改变 HIV 相关隐球菌性脑膜炎的管理模式具有巨大潜力。在 LMICs 中可持续获得包括氟胞嘧啶和两性霉素 B 在内的基本药物至关重要,这也是本文的重点。
