Cryptococcal meningitis causes morbidity and mortality worldwide. The burden of disease is greatest in middle- and low-income countries with a high incidence of human immunodeficiency virus (HIV) infection. Patients taking immunosuppressive drugs and some immunocompetent hosts are also at risk. Treatment of cryptococcal meningitis consists of three phases: induction, consolidation, and maintenance. Effective induction therapy requires potent fungicidal drugs (amphotericin B and flucytosine), which are often unavailable in low-resource, high-endemicity settings. As a consequence, mortality is unacceptably high. Wider access to effective treatment is urgently required to improve outcomes. For human immunodeficiency virus-infected patients, judicious management of asymptomatic cryptococcal antigenemia and appropriately timed introduction of antiretroviral therapy are important.
隐球菌性脑膜炎在全球范围内都会导致发病和死亡。在人类免疫缺陷病毒(HIV)感染高发的中低收入国家,疾病负担最为沉重。服用免疫抑制药物的患者以及一些免疫功能正常的宿主也有感染风险。隐球菌性脑膜炎的治疗包括三个阶段:诱导治疗、巩固治疗和维持治疗。有效的诱导治疗需要强效的杀真菌药物(两性霉素B和氟胞嘧啶),而在资源匮乏、疾病高流行地区这些药物往往难以获得。因此,死亡率高得令人无法接受。迫切需要更广泛地提供有效治疗以改善治疗效果。对于感染人类免疫缺陷病毒的患者,明智地管理无症状隐球菌抗原血症并适时引入抗逆转录病毒疗法非常重要。
