As far as I could tell,the article didn’t say how old this woman was. The fact that she had lupus may have made her more vulnerable to the virus. But who knows. Like Trump said “What have you got to lose?”
I would expect that having lupus would be a major co-morbidity factor, even if the drug she takes the lupus is the same one that helps with COVID-19.
I would think the negative of lupus would far outweigh the positive of having a body load of the drug that is supposed to help with COVID-19.
I don’t know that for sure, but that seems logical to me.
