TUESDAY, Jan. 12, 2021 (HealthDay Information) — Not like common pneumonia, COVID-19 pneumonia spreads like many “wildfires” all through the lungs, researchers say.
This may increasingly clarify why COVID-19 pneumonia lasts longer and causes extra hurt than typical pneumonia, based on the researchers at Northwestern Drugs in Chicago.
The analysis staff stated that their goal is to make COVID-19 extra like a foul chilly.
For the examine, the staff analyzed immune cells from the lungs of COVID-19 pneumonia sufferers and in contrast them to cells from sufferers with pneumonia attributable to different viruses or micro organism.
Whereas different types of pneumonia quickly infect giant areas of the lungs, COVID-19 begins in quite a few small areas of the lungs. It then makes use of the lungs’ personal immune cells to unfold throughout the lungs over many days and even weeks. That is much like how a number of wildfires unfold by a forest, the examine authors defined.
As COVID-19 pneumonia slowly strikes by the lungs, it leaves broken lung tissue in its wake and contributes to the fever, low blood pressure and organ injury frequent in COVID-19 sufferers, the staff stated.
The lengthy length of COVID-19 pneumonia, moderately than larger severity, could also be why it causes extra critical issues than different forms of pneumonia, based on the examine authors. The report was revealed on-line Jan. 11 within the journal Nature.
The researchers additionally recognized immune cells — macrophages and T cells — that might be necessary targets when treating extreme COVID-19 pneumonia. Macrophages sometimes shield the lungs, however could be contaminated by the new coronavirus and assist unfold the an infection by the lungs, the staff famous in a Northwestern information launch.
In a medical trial early this 12 months, the investigators plan to check an experimental drug that targets these immune cells in COVID-19 pneumonia sufferers. The drug reduces the inflammatory response of those immune cells.
“Our purpose is to make COVID-19 gentle as an alternative of extreme, making it corresponding to a foul chilly,” examine co-author Dr. Scott Budinger stated within the information launch. He’s chief of pulmonary and demanding care drugs at Northwestern College Feinberg College of Drugs.
Research co-author Dr. Richard Wunderink, professor of pulmonary and demanding care drugs at Feinberg and medical director of Northwestern Drugs’s ICU, added that “this effort actually represents a ‘moonshot’ in COVID-19 analysis.”
The U.S. Facilities for Illness Management and Prevention has extra on COVID-19.
