Oropharyngeal Immunoprophylaxis With High Polyphenolic Olive Oil as Clinical Spectrum Mitigating Factor in COVID-19.

Hospital General Nuestra Señora del Prado88 enrolled

Overview

Immunomodulation of local immune response at the oropharyngeal mucosa can hypothetically activate mucosal immunity, which can difficult SARS-CoV-2 main immune evasion mechanisms in early stages of the disease and send an effective warning to the adaptive immune system. There are previous studies on immunotherapeutic management of upper respiratory tract infections with olive polyphenols. The investigators would like to study if participants following oromucosal immunomodulation with tiny quantities of high polyphenolic olive oil (early harvest olive oil) could have more possibilities to have less severe symptoms and a better outcome after SARS-CoV-2 infection.

Interventions

High polyphenolic olive oil is normal olive oil obtained from early harvest olives, this early harvest olive oil has been widely used for culinary purposes for centuries. The investigators wanted to study if oromucosal immunoprophylaxis with small quantities of high polyphenolic olive oil (2 mL of olive oil equivalent to 5 mg of polyphenols) adiministered twice a day could have clinical mitigating effects on the disease caused by SARS-CoV-2 infection.The primary outcome was to determine the effect of high polyphenolic olive oil on Coronavirus disease incidence, duration and severity.
