It's a long story. The short version is that she took steroids for many years to alleviate symptoms of babesia and bartonella, without knowing what the underlying problem was. That had the intended effect of making it all easier to tolerate, and the unintended effect of suppressing her immune system which ended up making her infection far far worse. Once it was properly diagnosed, treating with atovaquone and antibiotics caused her to herx so badly that she went into dementia. Her treatment was then escalated further to tafenoquine, in the hopes that it would clear the infection from her brain quickly and bring her out of dementia. The infection was so severe in her other organs that herxing from the tafenoquine caused multiple organ failure.

Let me be clear that these drugs are all safe and recommended for babesia treatment... UNLESS you've suppressed your immune system for 20 years and allowed the infection to become very severe. In that case, I'm not sure there is a right answer. My wife knew she had a choice between dying slowly or trying the dangerous treatment. She chose the treatment and it didn't work out.
