Scientists Uncover Biological Signatures of the Worst Covid-19 Cases - The New York Times
That is rather interesting. So, essentially, the worst hit cases have bacterial and parasite immune responses that never shut off because COVID-19 is neither, and its continued existence continues to push stronger responses.
And, I well set off another screaming match... but this would also explain why Hydrochloroquine could be effective since its primary purpose is to fight the deadly symptoms of Malaria, a parasitic infection. So hydrocholoroquine would be effective if the patient's immune response is incorrectly responding to parasitic infection, rather than viral infection.
"Although the delineations aren’t always clear-cut, the immune system’s responses to pathogens can be roughly grouped into three categories: type 1, which is directed against viruses and certain bacteria that infiltrate our cells; type 2, which fights parasites like worms that don’t invade cells; and type 3, which goes after fungi and bacteria that can survive outside of cells. Each branch uses different cytokines to rouse different subsets of molecular fighters.
People with moderate cases of Covid-19 take what seems like the most sensible approach, concentrating on type 1 responses, Dr. Iwasaki’s team found. Patients struggling to recover, on the other hand, seem to be pouring an unusual number of resources into type 2 and type 3 responses, which is kind of “wacky,” Dr. Iwasaki said. “As far as we know, there is no parasite involved.”
It’s almost as if the immune system is struggling to “pick a lane,” Dr. Wherry said.
This disorientation also seems to extend into the realm of B cells and T cells — two types of immune fighters that usually need to stay in conversation to coordinate their attacks. Certain types of T cells, for instance, are crucial for coaxing B cells into manufacturing disease-fighting antibodies."
