摘要
Patients with prolonged febrile neutropenia are at high risk of invasive fungal infection, so it has been standard practice to initiate empirical antifungal therapy in these cases. However, this strategy is associated with important toxicity, so diagnostic test-guided preemptive antifungal therapy has been proposed as an alternative. Searching in Epistemonikos database, which is maintained by screening 30 databases, we identified three systematic reviews including twelve studies overall. Four randomized controlled trials addressed the question of this article. We combined the evidence using meta-analysis and generated a summary of findings following the GRADE approach. We concluded it is not clear whether preemptive strategy affects mortality because the certainty of the evidence is very low, but it might slightly decrease the use of antifungal agents in patients with prolonged febrile neutropenia. ; La neutropenia febril prolongada conlleva un alto riesgo de desarrollar infecciones fúngicas invasoras, por lo que habitualmente se administra terapia antifúngica empírica en estos casos. Sin embargo, esta se asocia a importantes efectos adversos, por lo que se ha propuesto como alternativa la estrategia "preemptive" o anticipada, es decir, la indicación de antifúngicos sólo ante la evidencia indirecta de infección fúngica invasora. Utilizando la base de datos Epistemonikos, la cual es mantenida mediante búsquedas en 30 bases de datos, identificamos tres revisiones sistemáticas que en conjunto incluyen doce estudios. Cuatro estudios aleatorizados evaluaron la pregunta abordada en este artículo. Realizamos un metanálisis y tablas de resumen de los resultados utilizando el método GRADE. Concluimos que no está claro si la estrategia "preemptive" tiene algún efecto sobre la mortalidad porque la certeza de la evidencia es muy baja, pero podría disminuir levemente el uso de antifúngicos en pacientes con neutropenia febril prolongada.
