I've been on arvs since 2002, but got sick with ME in 2012, so find it very unlikely ME is RV
Although it has to be said that only tenofovir, raltegravir and elvitegravir have been shown to inhibit gamma-retroviruses, so if there were a gamma-retrovirus in ME/CFS, I am not sure if antiretrovirals other than those three would be able to inhibit it.
By the way, I've been learning a bit about pharmacokinetics recently (the study of how drugs are absorbed and distributed in the body), and from what I can work out, the
in vivo anti-cytomegalovirus effect of raltegravir when you take this drug orally is very weak, almost non-existent (even though raltegravir has potent anti-cytomegalovirus effects in vitro).
So I don't think raltegravir would help combat any chronic cytomegalovirus infections a ME/CFS patient might have (even though I suggested earlier in this thread that raltegravir may inhibit herpesviruses).
There is not any data for the in vitro potency of raltegravir against EBV and HHV-6, so I cannot give any estimates on those; but if these two viruses are similar to cytomegalovirus, then we might assume that raltegravir may not have any in vivo potency against them either. So this suggests that the benefits raltegravir may have for ME/CFS are probably not a result of its anti-herpesvirus effects.
Pharmacokinetics is a useful thing to learn about, as it allows your to convert
in vitro antiviral study data into estimates for the
in vivo potency of that antiviral in the body.
