The lungs of patients with coronavirus disease are still damaged at least 3 months after being discharged from the hospital.
This was revealed in a medical study in the United Kingdom.
The joint study by the University of Sheffield and Oxford University found that even after recovery, the damage to the lungs of coronavirus patients did not appear in normal CT scans and clinical tests.
These patients are simply told that their lungs are working normally.
Further preliminary research also found that coronavirus patients who did not have to be hospitalized but had difficulty breathing were more likely to have lung damage, but more research is needed.
In a study published in the medical journal Radiology, experts found hyperpolarized Shannon MRI (X-ray MRI) scans and negative lung changes in some patients with coronavirus after more than 3 months, in some cases leaving the hospital.
Even after 8 months, the patients’ lungs were being damaged.
The researchers said the MRI showed parts of the lungs where the ability to use oxygen had been affected by the effects of the COVID, although CT scans showed everything was fine.
“The imaging technology we have developed will be introduced in other clinical centers as well,” he said.
He said that many patients with coronavirus still have difficulty breathing several months after being discharged from the hospital, although CT scans show that the lungs are functioning normally.
He said that this damage to the lungs could not be detected by ordinary tests as it affected the process of oxygen delivery to the food.
According to the researchers, although these are preliminary findings, the lungs of 70% of patients with Long Covid may have suffered similar damage, but further research is needed to determine how common the problem is. And how long can the situation improve?
Earlier, in early May 2021, a study by the University of Southampton in the United Kingdom found that one-third of hospitals from COVID `19 had evidence of adverse effects on the lungs even after one year.
In a study published in the medical journal The Lancet Receptive Medicine, experts, along with experts from the Chinese city of Wuhan, examined patients with severe COVID 19 pneumonia and found out what their condition was a year later.
For this purpose, 83 patients were treated in the hospital who were suffering from severe severe pneumonia.
These patients were examined for 3, 6, 9, and 12 months, ie they were examined every 3 months.
During each examination, the lung function was examined along with the medical analysis, for which a CT scan was taken of the lungs and a walking test was also taken.
A year later, most of the patients appeared to have fully recovered, but 5% were still having difficulty breathing.
One-third of patients’ lung functions did not return to normal, especially the ability of the lungs to carry oxygen to the blood.
CT scans of a quarter of the patients revealed changes in some small parts of their lungs and this was common in people who had serious changes in their lungs while being treated in the hospital.
The researchers said that the majority of patients with severe coliform pneumonia seem to recover completely, but some patients take several months to recover.
“Women have a higher rate of lung function than men and more research is needed to find out,” she said.
“We still don’t know what happens to patients after 12 months, so it’s important to continue research,” he said.
The researchers acknowledged that the number of patients in the study was not high and that additional research needed to confirm the findings, but they did identify some important things.
