Convalescent Plasma (PC) and Human Intravenous Anti-COVID-19 Immunoglobulin (IV Anti COVID-19 IgG) in Patients Hospitalized for COVID-19.

The study population will be patients (≥18 years) hospitalized by COVID-19 but still with an early form of the disease (in states 1-3 of the ordinal scale) who do not require mechanical ventilation (invasive or non-invasive) and who can give their consent informed. All the participants will receive non-specific supportive treatment for COVID-19 such as oxygen, IV liquid or corticosteroids. Additionally, they will be randomized to one of the following arms: Experimental arm 1: Plasma with inactivation/reduction of pathogens from convalescent patients with COVID-19 and who at the same time receive support therapy, in the 200 - 250 mL scheme, on days 1 and 3 of the intervention. Experimental arm: Anti-COVID-19 human immunoglobulin produced by Lifefactors Zona Franca S.A.S, intravenous at a dose of immunoglobulin 10% IgG solution (10% mL vial) for: Patient of 50 Kg or more, a dose of 50 mL will be applied on days 1 and 3 of treatment. Patients of less than 50 Kg, the dose will be 1 mL / Kg, will be applied on days 1 and 3 of treatment. This arm will be included once available. The supply of anti-COVID-19 human immunoglobulin produced by LifeFactors will be carried out once the national regulatory agency (Invima) grants authorization and/or the regulatory requirements for the production of medications are met. Control arm: Standard (specific) therapy for COVID-19 according to the suggested pharmacological recommendations of the Colombian Association of Infectious Diseases - ACIN. This therapy is subject to changes that are determined by the Colombian Health Regulatory Authorities.
