Re: Nitazoxanide is showing cures for HCV, immunal compromised, and HIV

uh, what exactly are you referring to in saying that nitazoxanide is a cure for "immune compromised" and HIV?
There's no evidence of such a thing. It has sometimes been used successfully to treat certain opportunistic infections that PWAs get (diarrheal infections like crypto), but there is no evidence I know of showing that it can reverse or halt the immune decline that is the hallmark of AIDS. There are many treatments for opportunistic infections (e.g. Bactrim for PCP) - none of these treat the underlying immune dysfunction.
Moreover, people with HIV respond less well to nitazoxanide than the immunocompetent. See, e.g.

(randomized clinical trial; nitazoxanide didn't help the people with HIV)
There will data on HCV soon enough.
