Lung Structure-Function In Survivors of Mild and Severe COVID-19 Infection — LIVECOVIDFREE  

Covid19 Clinical Trial

Official title: Lung Structure-Function In SurVivors of Mild and SEvere COVID-19 Infection: 129Xe MRI and CT For Rapid Evaluations and NExt-wave Healthcare Planning

Status Active, not recruiting

Clinical Trial Summary

This is a longitudinal study of the long-term impact of COVID-19 on the lungs. Participants will be followed over a period of up to 4 years and impacts of COVID-19 on the lungs will be measured with magnetic resonance imaging (MRI) using hyperpolarized xenon-129, pulmonary function tests, exercise capacity, computed tomography imaging and questionnaires.

Clinical Trial Description

This is a multisite longitudinal study of the long-term lung health impact of COVID-19 using hyperpolarized xenon-129 (129Xe) magnetic resonance imaging (MRI) over a period of up to 4 years.

In total 200 participants age ≥ 18 and <80 years who experienced a documented case of COVID-19 (documented by positive COVID-19 test and/or clinical history) will be screened and recruited if they meet all inclusion criteria at the 5 participating sites. Participants will be grouped in mild or severe COVID-19 infection (100 in each group) including 50 with symptoms and at least 50 participants who were hospitalized with COVID-19 infection, all of whom are within 3 months post recovery and non-infectious. Participants will attend up to 5 study visits over the 4 year period. (Visit 1 within 3 months post-COVID-19 recovery, Visit 2 at 24 ± 4 weeks, Visit 3 at 48 ± 4 weeks, Visit 4 at 78 ± 4 weeks, Visit 5 at 200 ± 16 weeks)

At all visits, participants will complete 129Xe MRI, questionnaires (St. George's Respiratory Questionnaire, COPD Assessment Test, Modified Medical Research Council Dyspnea Scale, Modified Borg Scale Breathlessness and Fatigue Questionnaire, Baseline Dyspnea Index Questionnaire and International Physical Activity Questionnaire), pulmonary function tests (Spirometry, Plethysmography, Forced Oscillation Technique, Fractional Exhaled Nitric Oxide, and Multiple Breath Nitrogen Washout), blood and sputum analysis, exercise testing (six-minute walk test). At Visit 1, participants will also complete computed tomography imaging at University Hospital, London Health Sciences Centre. Visits 2 and 4 have the option of being completed over the phone, in which case only questionnaires will be completed. Visit 5 is an optional 4-year follow-up. ;
