Abstract
in English, Spanish

Introduction: Recently, researchers from China and France reported on the effectiveness of chloroquine and hydroxychloroquine for the 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: To map published studies until March 25, 2020, on the use of chloroquine and its derivates in patients with COVID-19. Materials and methods: We searched on PubMed, Embase, Lilacs, and 15 registries from the World Health Organization’s International Clinical Trials Registry Platform for theoretical and empirical research in English, Spanish, Italian, French, or Portuguese until March 25, 2020, and made 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 hydroxychloroquine. The records are comments (n=9), in vitro studies (n=3), narrative reviews (n=2), clinical guidelines (n=2), as well as a systematic review, an expert consensus, and a clinical trial. Conclusions: One small (n=26), non-randomized, and flawed clinical trial 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 la eficacia de la cloroquina y la 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 la seguridad de estos medicamentos en la COVID-19. Objetivo. Describir el estado actual de la literatura científica publicada hasta el 25 de marzo de 2020 sobre el uso de la cloroquina o sus derivados en el manejo de pacientes con COVID-19. Materiales y métodos. Se hizo una revisión sistemática exploratoria en PubMed, Embase, Lilacs y 15 bases de datos de la Plataforma de Registros Internacionales de Ensayos Clínicos de la Organización Mundial de la Salud (OMS). Se incluyeron publicaciones empíricas y teóricas en inglés, español, italiano, francés o portugués, y se hizo una síntesis narrativa de los resultados. Resultados. Se incluyeron 19 documentos y 24 registros de ensayos clínicos (n=43) de 18.059 pacientes. El 66 % (16/24) de los ensayos están registrados en China. Nueve ensayos evalúan la cloroquina exclusivamente y ocho, la hidroxicloroquina. Los documentos son comentarios (n=9), estudios in vitro (n=3), revisiones narrativas (n=2), guías de práctica clínica (n=2), así como una revisión sistemática, un consenso de expertos y un ensayo controlado. Conclusiones. Un ensayo clínico pequeño (n=26), no aleatorizado y defectuoso, respalda el uso de la hidroxicloroquina en pacientes con COVID-19. Se requiere de manera urgente tener acceso a los resultados de otros ensayos clínicos para determinar la efectividad y la seguridad de la cloroquina y sus derivados en pacientes con COVID-19.
