Clinical Trial Summary

The physiological derangements in subjects suffering from long-term symptoms following a Covid-19 infection (Post-COVID-19 Syndrome) are poorly understood and evaluated. This study will recruit subjects with a clinical diagnosis of Post-Covid-19-syndrome) who are scheduled for either of lung function testing, cardiopulmonary exercise testing or cardiac ultrasound. Patients' symptoms will be correlated to physiological measures and compared to predicted values. In addition, in 20 patients, symptoms and physiological measures will be correlated to epigenetical alterations, or DNA-methylation patterns. In addition, a subset of patients will be examined a year after the baseline testing in order to follow the progress of the disease.

Description:

The physiological derangements in subjects suffering from long-term symptoms following a Covid-19 infection (Post-COVID-19 Syndrome) are poorly understood and evaluated. For example, the extent to which subjective symptoms correlate with physiological impairments are not known.

This study will recruit subjects with a clinical diagnosis of Post-Covid-19-syndrome) who are scheduled for either of lung function testing, cardiopulmonary exercise testing or cardiac ultrasound. Patients' symptoms will be correlated to physiological measures and compared to predicted values.

In addition, in 20 patients, symptoms and physiological measures will be correlated to epigenetical alterations, or DNA-methylation patterns. In addition, a subset of patients will be examined a year after the baseline testing in order to follow the progress of the disease.
