Brief Summary
This surveillance study will collect detailed clinical, laboratory, and radiographic data in coordination with biologic sampling of blood and respiratory secretions and viral shedding in nasal secretions in order to identify immunophenotypic and genomic features of COVID-19 -related susceptibility and/or progression. The aim: for the results obtained from this study to assist in generating hypotheses for effective host-directed therapeutic interventions, to help to prioritize proposals for such interventions, and/or optimize timing for administration of host-response directed therapeutics.

Outcome Measures
Primary Outcomes (7)
Mortality Rate Among COVID-19 Patients
The incidence of mortality in the first 28 days.
Day 1 to Day 28
Proportion of Patients with COVID-19 who Require Intensive Care Unit (ICU)-Level Care, Mechanical Ventilatory Support (MV), and/or Extracorporeal Membrane Oxygenation (ECMO) Over Time to Day 28
As a measure of disease acuity and severity.
Day 1 to Day 28
Proportion of Patients with COVID-19 who Develop Shock, Secondary Organ Failure, or Secondary Infection Over Time to Day 28
As a measure of disease acuity and severity.
Day 1 to Day 28
Mechanistic: Longitudinal Assessment of Viral Load by Semi-Quantitative Polymerase Chain Reaction (PCR) Over Time to Day 28
Ribonucleic acid (RNA) from the nasal swab will be used to assess SARS-CoV-2 viral load.
Day 1 to Day 28
Mechanistic: Antibody Isotype/Subclass Classification and Functionality Over Time through Day 28 and at follow-up through month 12
Focus on the immune response to SARS-CoV-2, seroconversion and immunoglobulin and transitions. Antibody isotypes present in a patient specimen(s) provide information about the timing of initial exposure and may provide insight on the progression of the disease and prognosis.
Up to 12 Months
Mechanistic: Longitudinal Assessment of Inflammatory Mediators as Collected Over Time to Day 28
Collected as part of clinical care.
Day 1 to Day 28
Mechanistic: Longitudinal Assessment of Markers of Myocardial Injury Over Time to Day 28
Collected as part of clinical care.
Day 1 to Day 28
Secondary Outcomes (9)
Duration of Mechanical Ventilation in Patients with COVID-19 Over Time to Day 28
Day 1 to Day 28
Proportion of Patients with COVID-19 with Requirement for New (Or Increased from Baseline if on Home Oxygen) Supplemental Oxygen Over Time to Day 28
Day 1 to Day 28
Requirement for Extracorporeal Membrane Oxygenation (ECMO) in COVID-19 Patients with COVID-19 Over Time to Day 28
Day 1 to Day 28
Mechanistic: Immune Cell Frequencies and Activation Status (CyTOF) in Blood and Endotracheal Aspirate over time Through Day 28 and In blood at Select Study Visits Through Month 12
Up to 12 Months
Mechanistic: Gene Expression (Transcriptomics) in Blood
Up to 12 Months
- +4 more secondary outcomes
Study Arms (1)
Surveillance cohort
Cohort descriptive data will include demographic variables (e.g. age, sex, race, ethnicity), clinical information on enrollment and key aspects of medical history (e.g. concomitant medications, for example). Patients will be longitudinally followed, up to 12 months.
Interventions
During patient hospitalization: Nasal secretion samples by nasal swabs (for non-intubated patients), whole blood (blood draw/phlebotomy) and sputum secretions by endotracheal aspiration (for intubated patients) will be obtained to proceed with immunologic analysis of samples. DNA will be collected from whole blood at enrollment for genetic analysis (e.g., genome-wide association study \[GWAS\]). After hospital discharge: Collection of biologic samples (involving nasal swabs and blood draw/phlebotomy) will occur up to 12 months.
Baseline data and assessments obtained as part of ongoing clinical care will be collected throughout hospitalization for COVID-19. After hospital discharge, clinical status and activity assessments will occur up to 12 months.
Eligibility Criteria
The study population consists of adult participants hospitalized with known or presumptive coronavirus disease 2019 (COVID-19), a human disease caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection.
You may qualify if:
- Individuals who meet all of the following criteria are eligible for enrollment as study participants:
- Participant and/or surrogate understands the data to be collected and the study procedures and is willing to participate in the surveillance cohort as described in the study information sheet;
- ≥ 18 years of age at the time of hospitalization; and
- Admitted to a hospital with presumptive or documented coronavirus disease 2019 (COVID-19), with confirmation of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) infection by Polymerase Chain Reaction (PCR).
You may not qualify if:
- Individuals who meet any of these criteria are not eligible for enrollment as study participants:
- Underlying medical problems which, in the opinion of the investigator may be associated with mortality unrelated to COVID-19 within 48 hours of hospitalization, or a decision by the patient or surrogate prior to hospitalization to limit care to comfort measures; or
- Medical problems or conditions such as pregnancy which might impact interpretation of the immunologic data obtained.
