Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Activation of markers of the innate immune system (in oropharyngeal scraping: relative concentration of dendritic cells; phenotypic analysis of leukocyte cells; transcriptional analysis of elements of molecules related to the immune response with expression at the level of epithelium and infiltrating leukocytes; quantification by ELISA of cytokines related to systemic inflammation such as IL-6, TNF alpha, IFN alpha and gamma, among other mediators of systemic inflammation, etc.). Measurement time: at baseline and, on days 4 and 8 post-treatment.

Key secondary outcomes:

Percentage of patients with appearance of the SARS-CoV-2 virus (by PCR-RT). Measurement time: Sometime during the 14-day follow-up. Percentage of patients with changes in the immune response: 1) Serum cytokine pattern (variable to verify aggravation); 2) Proportion of dendritic cells of the total (Cytology, FACs); 3) Ratio of activation of dendritic cells, NK and monocytes / macrophages by cytometry (activation markers, HLA DR and costimulatory factors by RT PCR); 4) Gene expression of TLR agonists in whole blood by RT-PCR; 5) Characterization of cellular subpopulations and senescence markers. Measurement time: bat baseline and, on days 4 and 8 post-treatment. Clinical Adverse Events (AE). They will be measured as: -AE occurrence (Yes, No), -AE description (name of the event), -AE intensity (mild, moderate, severe), -Causal relationship (unrelated, doubtful, possible, probable, Definitive), -Measures taken (None, Administration of any pharmacological therapy, Addition of a non-pharmacological therapy, Exit of the study, Hospitalization / prolongation of hospitalization), -Result (Fully resolved, Resolved with sequelae, Conditions in improvement, Present condition and unchanged, worsening, death caused by this event). Measurement time: daily throughout the follow-up of the subjects. Laboratory (numerical values of Blood chemistry test: hemogram, hematocrit, leukogram with differential, platelet count, prothrombin time, C-reactive protein, ALAT, ASAT, glycemia, creatinine, cholesterol, triglycerides, albumin and bilirubin). Measurement time: at baseline and, on days 4 and 8 post-treatment.
