What Causes Long-Term COVID?

Well is appears that Canadian researchers may have the answer why its so hard to recover from long-term COVID

CelebnHealth247.com has learned via an article from Globalnews that it appears that COVID is attacking the Red Blood Cells, the ones that carry oxygen to all parts of the body.

Olympic gold medalist Alex Kopacz may be used to being out of breath when pushing a bobsled, but last year after he was hospitalized for COVID-19, he experienced a very different kind of breathlessness.

He was put on oxygen for two months and experienced a number of other health setbacks in the months following his COVID-19 infection, including blood clots in his lungs and throughout his body.

Kopacz said:

It was hard to breathe and pretty much it was just going to be a matter of time to see if my body was going to heal from it.

It took him almost four months before he was back on his feet and breathing normally again. But without even an official diagnosis of so-called long COVID, the then-31-year-old didn’t have answers about what was happening to him.

That’s how he became involved in a new Canadian research trial looking at patients suffering from post-COVID syndrome — a study that has identified a potential key culprit causing some people to continue experiencing breathing issues months after contracting COVID-19.

A team of researchers based at five centers across Ontario have zeroed in on a microscopic abnormality in the way oxygen moves from the lungs and into the blood vessels of long COVID patients in their trial.

This abnormality could explain why these patients feel breathless and are unable to perform strenuous activities, says lead researcher Grace Parraga, Tier 1 Canada research chair in lung imaging at Western University’s Schulich School of Medicine & Dentistry.

She said:

Those feelings of breathlessness are completely consistent with our finding that we’re not moving the oxygen as efficiently as we should.

Many long COVID sufferers have been stumping doctors as to what’s wrong with them, because routine clinical tests and chest exams come back with normal readings.

The study, which was funded by the Ontario COVID-19 Rapid Research Fund, looked at 34 patients — 12 who had been hospitalized with COVID-19 and 22 others who had not been hospitalized.

Using an MRI technique developed by Western University that is five times as sensitive and has five times the spatial resolution of a CT scan, the researchers were able to see how tiny branches of air tubes in the lungs were moving oxygen into the red blood cells of their patients.

What Causes Long-term COVID:

Red blood cells are responsible for transporting oxygen from the lungs to the rest of the body. Any disruption in the flow of this oxygen to red blood cells will trigger the brain to say, ‘breathe more’ — resulting in a feeling of breathlessness, Parraga explained.

All 34 of the patients who participated in the study were experiencing problems in the level of oxygen being absorbed by their red blood cells.

And they all had the same result, regardless of the severity of their symptoms or whether they had been hospitalized for COVID-19 — another key find, Parraga said.

“All these patients had this abnormality. They all had really serious symptoms, so their exercise scores were low, they were breathless when they exercised and when we measured the oxygen levels in their blood in the tips of their fingers after exercise, that was also low.”

And these external measurements corresponded to the abnormality the researchers found in their MRI measurement of the lungs, she said.

“The takeaway is that now we know what’s wrong.”
