COVID may cause long-term lung damage: UK Study

Researchers at Sheffield and Oxford in United Kingdom, during a study, have identified persistent damage to lungs in COVID-19 patients at least three months after they were discharged from the hospital, and in some cases even longer. For the study, the researchers used a cutting-edge method if imaging. 

The researchers said the damage was not detected by routine CT scans and clinical tests, and the patients would consequently normally be told their lungs are normal. The study, which has been published in the journal Radiology – the world’s leading radiology journal, patients who have not been hospitalised with COVID-19 but who are experiencing long-term breathlessness may have similar damage in their lungs, and a larger study is needed to confirm this.

Researchers noted during the study that hyperpolarised xenon MRI (XeMRI) scans had found abnormalities in the lungs of some COVID-19 patients more than three months ? and in some cases, nine months – after leaving hospital, when other clinical measurements were normal.

Jim Wild, Lead author of the study and Head of Imaging and NIHR Research Professor of Magnetic Resonance at the University of Sheffield, said that “the findings of the study are very interesting.”

The 129Xe MRI is pinpointing the parts of the lung where the physiology of oxygen uptake is impaired due to long standing effects of COVID-19 on the lungs, even though they often look normal on CT scans.

A press release quoted Wild as saying: “It is great to see the imaging technology we have developed rolled out in other clinical centres, working with our collaborators in Oxford on such a timely and clinically important study sets a real precedent for multi-centre research and NHS diagnostic scanning with 129Xe MRI in the UK.”

The study’s Principal Investigator Professor Fergus Gleeson, Professor of Radiology at the University of Oxford and Consultant Radiologist at Oxford University Hospitals (OUH) NHS Foundation Trust, said: Many COVID-19 patients are still experiencing breathlessness several months after being discharged from hospital, despite their CT scans indicating that their lungs are functioning normally.”

Gleeson added: “Our follow-up scans using hyperpolarised xenon MRI have found that abnormalities not normally visible on regular scans are indeed present, and these abnormalities are preventing oxygen getting into the bloodstream as it should in all parts of the lungs.”

The study, which is supported by the NIHR Oxford Biomedical Research Centre (BRC), has now begun testing patients who were not hospitalised with COVID-19 but who have been attending long COVID clinics.

Gleeson said: “Although we are currently only talking about early findings, the XeMRI scans of non-hospitalised patients who are breathless – and 70 per cent of our local patients with Long COVID do experience breathlessness ? may have similar abnormalities in their lungs. We need a larger study to identify how common this is and how long it will take to get better.”

“We have some way to go before fully comprehending the nature of the lung impairment that follows a COVID-19 infection. But these findings, which are the product of a clinical-academic collaboration between Oxford and Sheffield, are an important step on the path to understanding the biological basis of long COVID and that in turn will help us to develop more effective therapies,” Gleeson added.
