About a week ago I saw a story on CNN about some researchers
who made a connection between glutathione and susceptibility to
illness in aids patients. They said that if their correlation
was correct then some help for aids patients might be available
as it was possible to use external means to increase the body’s
store of glutathione. Unfortunately the story stopped there.
What I want to know is what method do these researchers have in
mind to significantly increase the body’s supply of glutathione?
I’m under the impression that taking it orally does little good
as the digestive system will tear most or all of it apart before
it can be absorbed into the body. What did they have in mind?
Injections? Enteric coated tablets? Or perhaps some method of
getting the body to produce more on its own without an added
external supply?
Information would be appreciated. If information is lacking,
I’d be happy to get an e-mail address where I can contact CNN
and see if they can give me some more information.
Thanks,
Kevin

NAC supplementation has been considered by the Stanford team
and (apparently) been found effective at elevating glutathione levels
back toward a normal level. This team of researchers seem to be
associating such supplementation with a more positive outcome
although I still have to hear them say that this is statistically
significant. NAC supplementation had been considered before
with mixed findings. It’s now certainly sounding like a good idea.
I’ve also attached a reminder that there is a timed release version
of NAC available (apparently the standard capsules have a very
short half-life of 1-1.5hrs) and a copy of the latest press release.

Glutathione Helps AIDS Survival, Reuters – Tuesday March 4 1:35 PM EST
NEW YORK – Maintaining healthy levels of a peptide
called glutathione may play a "pivotal" role in slowing the
progression of AIDS, researchers say.
"People with HIV who have lower glutathione levels (also) have
a much lower probability of surviving over the course of three
years than do people with normal glutathione levels," concludes
Stanford University School of Medicine geneticist Dr. Leonard
Herzenberg.
Glutathione (GSH) is a molecule involved in a range of normal
cell activities, including cell division and the clean-up of
intracellular toxins. But a low glutathione level effectively
"decreases cell survival, alters (immune system) T cell
functions, and increases HIV replication" in HIV-infected
cells, researchers say.
They add that GSH-level measurements may be an accurate marker
of AIDS progression. Traditionally, physicians have assessed
the condition of HIV-infected patients by measuring levels of
CD4 cells, part of the immune-system. CD4 counts of 1,000 cells
per milliliter (ml) of blood are normal in healthy, uninfected
individuals. These numbers drop precipitously in those infected
with HIV. CD4 levels under 200 cells/ml are thought to leave
AIDS patients vulnerable to a number of life-threatening
opportunistic infections.
But CD4 counts may not tell the whole story, according to the
study.
Herzenberg’s team divided 204 HIV-positive, (but
AIDS-asymptomatic), patients into two groups. They gave one
group a GSH-boosting drug called N-acetylcysteine (NAC), and
the other group a placebo.
Ninety-nine of the 204 Stanford study subjects had initial CD4
counts of under 200 cells/ml. Most of the 99 who received
placebo (and thus maintained low glutathione levels) died
within the three-year study period.
"In contrast," said Herzenberg, "of the 28 people who started
the study with low CD4 counts but maintained normal glutathione
levels, 23 survived. In other words, about 80% of these people
survived, even though their CD4 cell counts indicated their
survival was unlikely."
Herzenberg believes "glutathione levels matter to patient
survival," and the study says clinical measurements of those
levels "emerges as a powerful yardstick for predicting survival
in HIV infection."
And Herzenberg believes that boosting GSH levels can keep AIDS
patients healthier longer. "We know that NAC will raise
glutathione levels in patients. Therefore, it’s logical to
suggest that NAC will help HIV patients live longer," he says.
NAC, a drug the study calls "inexpensive (and) nontoxic," works
by supplying the amino acids crucial to the replenishment of
cellular GSH.
However, other factors deplete the body’s GSH. Ultraviolet
radiation (usually from sunlight), drinking, and the
consumption of acetaminophen-containing drugs (like Tylenol)
can actually lower GSH levels, the researchers warn. Avoiding
those factors would "minimize GSH deficiency in HIV-infected
individuals," they say.
The study "provides the first clear indication that GSH
deficiency plays a pivotal role in determining how quickly the
final stages of HIV disease progress." Herzenberg says clinical
trials assessing impact of NAC administration on long-term HIV
patient survival is the next logical step in research on the
subject. SOURCE: Proceedings of the National Academy of
