The use of Hydroxychloroquine during the COVID-19 pandemic: a literature review study




COVID-19; SARS-CoV-2; Hydroxychloroquine.


COVID-19 is an infectious disease caused by SARS-CoV-2, has a high transmission rate and has resulted in thousands of registered deaths worldwide. Currently, there are no clinical studies proving the effectiveness of specific drugs against SARS-Cov-2. However, previous experiences with similar viruses indicated potential effectiveness for certain drugs, including the use of Hydroxychloroquine (HCQ). At the beginning of the COVID-19 pandemic, the World Health Organization and the Ministry of Health of Brazil guided the use of HCQ as a therapeutic option. However, its role in viral infection by SARS-CoV-2, in addition to its real benefits in vivo, was unknown. Therefore, the aim of this study was to conduct a literature review on the use of HCQ in cases of COVID-19, and to discuss the results found in studies that performed in vitro and in vivo tests, in order to investigate its therapeutic efficacy. The review was carried out using descriptors in a computerized database. The antiviral efficacy of HCQ against SARS-CoV-2 in vitro has been described by several authors, inhibiting virus replication and mediating cytokine storm through its immunomodulatory effects. However, in vivo analyzes in complex organisms showed no effect on reducing viral load, as well as no clinical benefit to the patient. Thus, although preliminary in vitro results have shown to be positive and promising, evidence from randomized clinical trials indicated that HCQ did not cause the same effects in vivo against COVID-19.
