Description of intervention(s) / exposure
The study is a multi-centred prospective observational study involving a cohort of 30 adults who are at least 30 days and no more than 45 days post COVID-19 pneumonia diagnosis. Recruited patients will have an 18F-FDG PET/CT scan which will be assessed for persistent areas of increased inflammation in their lung tissue and for inflammation of blood vessels, indicated by measuring the amount of FDG seen in the aorta. The scan will be performed no less than 30 and no more than 45 days from the date of the COVID-19 diagnosis.

Outcomes
Primary outcome [1] 324294 0
18FDG uptake in the lung tissue will be assessed both visually to determine characteristic uptake patterns and quantitatively by measuring the mean standard uptake values of FDG in the lungs.
Timepoint [1] 324294 0
The PET/CT scan will be performed at minimum of 30 days and no more than 45 days post COVID-19 pneumonia diagnosis. The visual and quantitative assessments of the scan will be done within 6 months of the PET/CT scan.
Secondary outcome [1] 384265 0
Aortic inflammation will be quantitatively assessed by measuring the mean standard uptake values of FDG in the aorta.
Timepoint [1] 384265 0
The PET/CT scan will be performed at minimum of 30 days and no more than 45 days post COVID-19 pneumonia diagnosis. The visual and quantitative assessments of the scan will be done within 6 months of the PET/CT scan.

Statistical methods / analysis
Sample size will be 30 for this research study. In our previous study of 22 CAP patients
69% of the participants showed persistence or worsening of 18FDG uptake at the 30-day scan. The proposed study of 30 participants would give adequate power as COVID-19 pneumonia is a more severe form of pneumonia compared to CAP caused by other pathogens.
In the unlikely event that there may be some attrition from consent to the PET imaging process, additional participants may be recruited into the study to ensure a total of 30 participants complete the required PET scans.

Summary
Brief summary
COVID-19 is associated with a high rate of lung infection (pneumonia), and it is uncertain for how long the inflammatory changes of pneumonia remain in the lungs once people have recovered from their symptoms and whether this is associated with adverse long-term outcomes. This study aims to determine if there are persistent areas of inflammation in the lungs in people who have recovered clinically from COVID-19 pneumonia, and also to assess whether there is evidence of increased blood vessel inflammatory activity in these people. As inflammation has an important role in the development and progression of cardiovascular disease, the persistence of inflammation may be a predictor of increased risk for future heart disease. 18FDG-PET/CT is an imaging test which is very sensitive to detection of inflammation.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
There is only a small cohort of patients in this study thus it would be impossible to guarantee their anonymity should their data be made available.
