TUESDAY, Jan. 12, 2021 (HealthDay Information) — In contrast to 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, in line with the researchers at Northwestern Medication in Chicago.
The analysis workforce stated that their intention is to make COVID-19 extra like a nasty chilly.
For the examine, the workforce 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 forms of pneumonia quickly infect massive 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 via a forest, the examine authors defined.
As COVID-19 pneumonia slowly strikes via the lungs, it leaves broken lung tissue in its wake and contributes to the fever, low blood strain and organ harm widespread in COVID-19 sufferers, the workforce stated.
The lengthy length of COVID-19 pneumonia, quite than higher severity, could also be why it causes extra critical issues than different forms of pneumonia, in line with the examine authors. The report was printed on-line Jan. 11 within the journal Nature.
The researchers additionally recognized immune cells — macrophages and T cells — that may very well be vital targets when treating extreme COVID-19 pneumonia. Macrophages sometimes shield the lungs, however might be contaminated by the brand new coronavirus and assist unfold the an infection via the lungs, the workforce 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 objective is to make COVID-19 gentle as a substitute of extreme, making it corresponding to a nasty chilly,” examine co-author Dr. Scott Budinger stated within the information launch. He’s chief of pulmonary and important care drugs at Northwestern College Feinberg Faculty of Medication.
Research co-author Dr. Richard Wunderink, professor of pulmonary and important care drugs at Feinberg and medical director of Northwestern Medication’s ICU, added that “this effort really represents a ‘moonshot’ in COVID-19 analysis.”
The U.S. Facilities for Illness Management and Prevention has extra on COVID-19.
