NCT04510012

Brief Summary

The Investigators plan to study the innate and adaptive immune response, the inflammatory response, and associated complications such as complement activation and neurological damage in SARS-Cov-2 infected individuals. Patients with mild, moderate and severe COVID-19 disease will be enrolled.

Study Arms (3)

Mild COVID-19

SARS-Cov-2 infected individuals with mild symptoms (WHO Ordinal Scale for Clinical Improvement in COVID-19: scores 1-2)

Other: Analysis of cytokine response, innate and adaptive immune response, complement activation, and serum neurofilaments as a marker of neurological damage.

Moderate COVID-19

SARS-Cov-2 infected individuals with moderate symptoms (WHO Ordinal Scale for Clinical Improvement in COVID-19: scores 3-4)

Other: Analysis of cytokine response, innate and adaptive immune response, complement activation, and serum neurofilaments as a marker of neurological damage.

Severe COVID-19

SARS-Cov-2 infected individuals with severe symptoms (WHO Ordinal Scale for Clinical Improvement in COVID-19: scores 5-8)

Other: Analysis of cytokine response, innate and adaptive immune response, complement activation, and serum neurofilaments as a marker of neurological damage.

Interventions
