Brief Summary

The newly recognised disease COVID-19 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which by early December 2019 had spread from China to the rest of the world, especially Europe, the United States, Latin America, and India, with over 86 million confirmed cases and over 1.870.000 deaths (5th January, 2021). The clinical spectrum of SARSCoV- 2 infection is wide, encompassing asymptomatic infection, mild upper respiratory tract illness, and severe viral pneumonia with respiratory failure and even death.

According to retrospective data from China regarding 1099 patients with laboratory-confirmed COVID-19, at the time of admission to hospital, the most common symptoms were cough (67.8%), fever (43%), and fatigue (38.1%), and less frequently myalgia/arthralgia (14.9%), a sore throat (13.9%) and headache (13.6), while nausea or vomiting (5.0%) and diarrhoea (3.8%) were uncommon. Similar clinical characteristics are also encountered in European and US COVID-19 patients.

Given the rising global death toll associated with the pandemic, in the past few months we have witnessed a race to find drug/biological treatments to save the lives of hospitalized, severely ill patients, as well as to develop vaccines. To this end, randomized clinical trials are underway to test experimental drug candidates, or repurposed medicines. At this time, it is crucial to focus on primary care physicians and initial mild symptoms at home in COVID-19 patients.

Recently recommendations have been produced to treat this illness at home based on the pathophysiologic and the pharmacologic rationale and the available clinical evidence of efficacy in COVID-19 patients, including results of published clinical trials, for each of the recommended class of drugs. These recommendations have taken advantage from the long term experience of an infection disease specialist and other clinicians of Bergamo Hospital, who used their know-how and sound judgment to treat COVID-19 patients at home.

Because the common early mild symptoms of COVID-19 highlight a systemic inflammatory process, there is the recommendation of using anti-inflammatory agents to limit excessive host inflammatory responses to the viral infection, including non-steroidal anti-inflammatory drugs and corticosteroids.

Moreover, COVID-19 is a particularly debilitating illness, and, apart from causing patients to be bedridden, there is evidence that in SARS-CoV-2 infection, dysregulation of the coagulation cascade and fibrinolytic system occur. Therefore, COVID-19 patients are exposed to the risk of thromboembolic events, independently of age, and anticoagulant prophylaxis is recommended, unless contraindicated.

Comparative analysis of patient cohorts with long-enough follow-up in everyday clinical practice may offer a good alternative to randomized clinical trials to evaluate effectiveness of novel therapies. Thus, we will use this approach in an observational retrospective matched-cohort study to compare a cohort of COVID-19 patients treated at home by their family phisicians according to the proposed recommendations with another cohort of similar patients treated with other therapeutic regimens.

Our working hypothesis is that following the recommendations the inflammatory processes and thus symptoms resolve faster than with other therapeutic approaches, while safe achieving similar rates of complete remission of the illness.
