ABSTRACT
The emerging novel coronavirus disease 2019 has caused a global outbreak and significant public health concern. The World Health Organization (WHO) has announced a coronavirus disease outbreak a pandemic with a global public health emergency of international concern. As of now, 12th April 2020 almost 18,37,404 cases have been confirmed globally (in 209 countries) with almost 1,13,274 fatalities. This increasing number has created anxiety throughout the world, which has severely affected the whole world's culture, societies, behavioral patterns, peace and economics. At present, research on novel coronavirus is in the preliminary stage. There is no vaccine or specific antiviral to treat coronavirus disease. Also, very few case studies are available;hence it has become difficult to treat and to control this pandemic situation. In view of this, the present systematic review is done to highlight clinical epidemiology features, radiographic characteristics, and potential drugs based on available clinical case reports. Biomarkers for early diagnosis and impact of age, sex, pre-existing comorbidity on COVID-19 is also discussed. Further, this paper also outlines various possible antiviral chemical drug agents that can be potential and promising to treat this coronavirus disease in 2019. This review may be helpful for the medical practitioner, public health workers and government authorities to manage and deal with novel coronavirus disease 2019.Copyright © 2021 Bentham Science Publishers.
ABSTRACT
Hydroxychloroquine (HCQ) as a drug grabbed serious attention of whole world in dealing with COVID-19 pandemic. Recently some in-vitro and in-vivo study showing possible inhibition of SARS-CoV-2 by use of HCQ. However at the same time, some case studies showing NO clinical benefit/poor clinical outcome with substantial detrimental adverse effects by use of HCQ in treatment of coronavirus disease-2019. Thus, the HCQ use (in COVID-19 treatment) is of current international interest, although a consensus has not yet been reached. More evidences are still required to prove efficacy of HCQ against COVID-19. In view of this, the present review highlights the current ongoing research related to use of HCQ in treatment coronavirus disease-2019. The present review will discuss the possible anti-viral mechanism of HCQ, prophylaxis strategy and effect of HCQ against SARS-CoV-2 virus in-vitro study. Further this review also summarizes and debates all available clinical trials/case studies of HCQ use against COVID-19 (with clinical outcome). Finally possible detrimental adverse effects are also discussed considering the public health and pharmacovigilance concern.
