Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to understand why some people experience long term effects, such as shortness of breath and fatigue, after a severe COVID-19 infection

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Each participant will be in the study for approximately 12 months and will be required to come to Mayo Clinic for 3 visits. These visits will take place approximately 2-3 months after confirmed COVID-19 diagnosis (visit 1), 6 months after diagnosis (visit 2), and 12 months after diagnosis (visit 3).

Comprehensive clinical evaluation and symptom characterization, quantitative lung CT image analysis and pulmonary function testing, and quality of life questionnaires will be obtained at each visit. Bronchoscopy with BAL (collected at visits 1 and 3 only) and blood samples (collected at all visits) will dissect the dynamic immunological and molecular signatures in the respiratory tract and in the circulation longitudinally. We will also perform highly sensitive viral reservoir or remnant assays to address the potential contribution of viral factors in regulating chronic lung conditions post-acute COVID-19.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Sequelae group

COVID-19 convalescents that recover from prior severe acute diseases requiring hospitalization and who will be at high risk of chronic lung sequelae (with an estimate of \>50% having moderate to severe sequelae based on current literature)

Bronchoscopies and Bronchoalveolar Lavages (BALs)

Intervention Type PROCEDURE

Bronchoscopies use a thin, lighted tube, which enters through the mouth or nose and moves down the throat to the airways to look at the lungs. BALs are done during bronchoscopies to collect samples from the lungs for testing. During this procedure, a saline solution is put through the tube to wash the airways and collect a fluid sample.

Chest Tomography (CT)

Intervention Type DIAGNOSTIC_TEST

X-ray to create images of the bones and internal organs of the body

Electrocardiogram (ECG)

Intervention Type DIAGNOSTIC_TEST

Measures the electrical activity of the heart by using sticky pads that are placed on your chest and limbs.

Pulmonary function tests (PFTs)

Intervention Type DIAGNOSTIC_TEST

Testing to measure how well lungs are working

6 minute walk test (6MWT)

Intervention Type DIAGNOSTIC_TEST

Walking test to see how well the lungs function with exercise over 6 minutes

Recovery group

Age and gender matched individuals who had mild SARS-CoV-2 infection and experienced complete resolution of symptoms

Bronchoscopies and Bronchoalveolar Lavages (BALs)

Intervention Type PROCEDURE

Bronchoscopies use a thin, lighted tube, which enters through the mouth or nose and moves down the throat to the airways to look at the lungs. BALs are done during bronchoscopies to collect samples from the lungs for testing. During this procedure, a saline solution is put through the tube to wash the airways and collect a fluid sample.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

For the Sequelae Group

* Age ≥18 years at screening, PCR confirmed COVID19 illness (+PCR defines day 0 of illness), hospitalization for COVID-19, absence of pre-existing history of interstitial lung disease, or significant other lung disease.
* Severity of illness will be categorized as moderate disease (supplemental oxygen need 1-8L at any time during hospitalization), severe disease (need for high flow oxygen delivery ≥8L at any time during hospitalization) and critical illness (need for ICU admission or mechanical ventilation).

Control Recovery Group

* Age ≥18 years at screening
* PCR confirmed COVID-19 cases who had nonsymptomatic or mild acute infection that do not require hospitalization 7,48,49
* Absence of pre-existing history of interstitial lung disease, or significant other lung disease, absence of any ongoing respiratory and systemic symptoms.

Exclusion Criteria

* Inability to provide informed consent, evidence of pre-existing interstitial lung disease or chronic lung disease;
* Active cigarette smoking, vaping or other inhalation use.
* Immunocompromised host status due to ongoing therapy with methotrexate, CellCept, azathioprine, rituximab, cyclophosphamide or other biologic agents;
* \> 20 pack year smoking history.
