Abstract
BACKGROUND: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is the causative agent of coronavirus disease 2019 (COVID-19), which was declared a global pandemic by the World Health Organization on 11(th) March 2020. The treatment guidelines for COVID-19 vary between countries, yet there is no approved treatment to date. AIM: To report any evidence of therapeutics used for the management of patients with COVID-19 in clinical practice since emergence of the virus. METHODS: A systematic review protocol was developed based on the PRISMA statement. Articles for review were selected from Embase, Medline and Google Scholar. Readily accessible peer-reviewed, full articles in English published from 1(st) December 2019 to 26(th) March 2020 were included. The search terms included combinations of: COVID, SARS-COV-2, glucocorticoids, convalescent plasma, antiviral and antibacterial. There were no restrictions on the types of study eligible for inclusion. RESULTS: Four hundred and forty-nine articles were identified in the literature search; of these, 41 studies were included in this review. These were clinical trials (N=3), case reports (N=7), case series (N=10), and retrospective (N=11) and prospective (N=10) observational studies. Thirty-six studies were conducted in China (88%). Corticosteroid treatment was reported most frequently (N=25), followed by lopinavir (N=21) and oseltamivir (N=16). CONCLUSIONS: This is the first systematic review to date related to medication used to treat patients with COVID-19. Only 41 studies were eligible for inclusion, most of which were conducted in China. Corticosteroid treatment was reported most frequently in the literature.
