The COVID-19 pandemic has been characterized by high morbidity and mortality, especially in certain subgroups of patients. To date, no treatment has been shown to be effective in controlling this disease in hospitalized patients with moderate and / or severe cases of this disease. Hydroxychloroquine and lopinavir / ritonavir have been shown to inhibit SARS-CoV viral replication in experimental severe acute respiratory symptoms models and have similar activity against SARS-CoV2. Although widely used in studies of critically ill patients, to date, no study has demonstrated its role on the treatment of high-risk, newly diagnosed patients with COVID-19 and mild symptoms.
In December 2019 a series of viral pneumonia cases were reported in the city of Wuhan, China. A new subtype of coronavirus has been identified as the causative agent of this condition. On February 11, 43,103 cases had already been described and on this day the World Health Organization (WHO) named this disease as COVID-19. With. The disease had spread out to several countries on different continents and on March 11, WHO declared a state of worldwide pandemic. Today (April 25, 2020) there are 2,719,897 cases and 187,705 deaths documented, with a global case-fatality ratio of 6.9%. To date, no treatment has been identified as effective in combating this disease which has been identified as with high mortality, therefore there are no specific therapeutic options. So far, efforts have been focused on the treatment of patients hospitalized with dyspnea and, although several promising drugs are being evaluated, none has demonstrated effectiveness in reducing morbidity and mortality at this stage of the disease, suggesting that perhaps the best time to use medications either before the onset of severe symptoms of respiratory distress. Thus, we propose the use of two drugs which experimentally have shown activity against SARS-CoV2 and being used in severely ill patients with COVID-19. Our hypothesis is that perhaps using such drugs before onset of complications will allow better outcomes on this patient population.
