"..COVID-19 damages the hemoglobin, impairing the ability of red blood cells to transport oxygen throughout the body, compromising the lungs and resulting in Acute Respiratory Distress Syndrome (ARDS), Italian pharmacology scholar Annalisa Chiusolo explained to The Jerusalem Post.

If her thesis is correct, it would resolve many outstanding questions about the novel coronavirus, such as the greater vulnerability of men – specifically male diabetics – to become seriously ill from the virus, as well as the lower rate at which pregnant women and children contract COVID-19…"

"…As a pharmacist, Chiusolo next evaluated the use of hydroxychloroquine to treat SARS-CoV-2, which in some cases has been found to reduce hospitalizations from the virus. Hydroxychloroquine is currently in use for the treatment of autoimmune diseases worldwide, such as lupus and rheumatoid arthritis, and has been used for years to treat malaria.

She said that in addition to the drug’s antiviral and immunomodulatory effect, it binds to the ferriprotoporphyrin of the ecgonine methyl ester (EME), blocking the key enzyme of malaria. “So, I thought this same mechanism could be used against SARS-CoV-2… Indeed, a study by a Chinese university shows that SARS-CoV-2 binds to the beta chain of hemoglobin, inhibiting EME metabolism.”

Ferriprotoporphyrin is the group responsible for the oxygen binding of hemoglobin…"
