Sept. 25, 2023 — As we proceed to reside with COVID-19, sufferers and medical doctors will be taught extra in regards to the causes infections can vary from asymptomatic to very critical.

New analysis from Northwestern College and the College of Wisconsin, nonetheless, is pointing to bacterial pneumonia because the trigger of many extreme COVID deaths. Deceased COVID sufferers studied weren’t proven to have skilled irritation in any respect. As a substitute, the researchers, utilizing machine studying to investigate information, discovered that half of the severely unwell COVID sufferers who required a ventilator had bacterial pneumonia as a secondary an infection. They didn’t discover proof of a cytokine storm in these sufferers; as a substitute of dying from organ harm or failure as a result of COVID, they died of pneumonia.
“Critically unwell sufferers who recovered from pneumonia have been extra prone to reside,” stated Benjamin D. Singer, MD, senior creator of the examine, professor of pulmonary medication, and a Northwestern Medication pulmonary and important care physician in Chicago.

In COVID-19, cytokines have been thought to launch irritation that may flow into by way of the physique and trigger demise.
A brand new examine from CSIR-Institute of Microbial Expertise in Chandigarh, India, and M. M. Engineering Faculty in Ambala, India, for instance, discovered that controlling this inflammatory issue is important with a purpose to deal with COVID. Italian researchers additional discover that hyperinflammation performs a particular position in extreme sickness in COVID sufferers.
Further new analysis does present that particular micro organism may cause unfavorable outcomes for COVID sufferers. A examine from the New York College Grossman Faculty of Medication discovered that micro organism from the intestine could transfer into the blood of sufferers with extreme COVID. “Micro organism circulating within the blood can speed up problems in these COVID sufferers,” stated examine co-author Jonas Schluter, PhD of the Institute for Programs Genetics and assistant professor of microbiology at NYU Grossman in New York Metropolis.
Can these findings have an effect on any affected person who’s identified with COVID-19 and could also be at excessive danger for problems? Doubtlessly, sure.
