Description Introduction: Recently, researchers from China and France reported on chloroquine and hydroxychloroquine's effectiveness for inhibition of SARS-CoV-2 viral replication in vitro. Timely dissemination of scientific information is key in times of pandemic. A systematic review of the effect and safety of these drugs on COVID-19 is urgently needed.
Objective: Map published knowledge until March 25, 2020, on the use of chloroquine and its derivates in patients with COVID-19.
Materials and methods: a scoping review searched PubMed, Embase, Lilacs, and 15 registries from the WHO’s International Clinical Trials Registry Platform for theoretical and empirical research in English, Spanish, Italian, French, or Portuguese, until March 25, 2020. We conducted a narrative synthesis of the results.
Results: we included 19 records and 24 trial registries, (n=43) including 18,059 patients. China registered 66% (16/24) of the trials. Nine trials evaluate chloroquine exclusively and eight trials evaluate hydroxychloroquine exclusively. The records are comments (n=9), in vitro studies (n=3), narrative reviews (n=2), clinical guidelines (n=2), and a systematic review, an expert consensus, and a clinical trial.
Conclusions: One small, non-randomised, and flawed clinical trial (n=26) supports hydroxychloroquine use in patients with COVID-19. There is an urgent need for more clinical trial results to determine the effect and safety of chloroquine and hydroxychloroquine on COVID-19.
Introducción. Recientemente, investigadores chinos y franceses reportaron eficacia de la cloroquina e hidroxicloroquina para inhibir la replicación in vitro del virus SARS-CoV-2. La diseminación oportuna de la información científica es clave en tiempos de pandemia. Es urgente contar con una revisión sistemática sobre el efecto y seguridad de estos medicamentos en el COVID-19.
Objetivo. Describir el estado actual de la literatura científica publicada hasta marzo 25 de 2020, sobre el uso de la cloroquina o sus derivados en el manejo de pacientes con COVID-19.
Material y métodos. Revisión sistemática exploratoria que incluyó PubMed, Embase, Lilacs y 15 bases de datos de Plataforma de Registros Internacionales de Ensayos Clínicos de la OMS. Incluimos publicaciones empíricas y teóricas en inglés, español, italiano, francés, o portugués. Realizamos una síntesis narrativa de los resultados.
Resultados. Se incluyeron 19 documentos y 24 registros de ensayos clínicos, (n=43) sumando 18,059 pacientes. 66% (16/24) de los ensayos están registrados en China. Nueve ensayos evaluarán la cloroquina exclusivamente, y ocho la hidroxicloroquina exclusivamente. Los documentos son comentarios (n=9), estudios in vitro (n=3), revisiones narrativas (n=2), guías de práctica clínica (n=2), y revisión sistemática, consenso de expertos y ensayo controlado (n=1, respectivamente).
Conclusiones. Un ensayo clínico pequeño (n=26) no aleatorizado y con fallos, soporta el uso de hidroxicloroquina en pacientes con COVID-19. Se requiere de manera urgente tener acceso a resultados de ensayos clínicos adicionales para determinar la efectividad y seguridad de la cloroquina y sus derivados en pacientes con COVID-19.
