This is a
protocol that appears to actually cure HIV.
It depends of introducing the genes of a door who is naturally immune,
but as this case shows, it eliminates the disease or we think so. HIV hides and reemerges when opportunity
arises. Yet this is a pretty good start.
The current
protocols call for driving the HIV out of the blood stream back into its hidey
holes and largely keeping them there.
Not perfect, but certainly good enough to allow the victim to die of old
age.
I presume
that in the test case they have suspended the cocktail and HIV has failed to
reemerge. That sure looks like a cure
and they are justified saying so. We may
have this in some form of general usage pretty quick
It is worth
recalling that HIV victims are now surviving and all sure would love to see
this horror off. This happens to be the
first believable solution.
Patient
reportedly cured of HIV infection after stem cell transplant

An
HIV-infected man who received stem cell treatment for leukemia from a donor
with natural resistance to HIV infection appears to have been cured of HIV,
according to a report on the NAM aidsmap website. The
treatment, which was carried out in 2007, opens the possibility of a cure for
HIV infection through the use of genetically engineered stem cells.
The
donor who provided the bone marrow for the transplant had a natural resistance
to HIV infection due to the absence of the CCR5 co-receptor from his cells. HIV
most commonly uses CCR5 as a “docking station” to enter its target CD4 cells
and carriers of a genetic mutation of a portion of the CCR5 gene called
CCR5-delta 32 homozygosity have a reduced risk of becoming infected with HIV.
For a
period of 38 months after the stem cell transplant the patient continued to
receive immunosuppressive treatment to prevent rejection of the stem cells.
During this time the donor CD4 cells repopulated the mucosal immune system of
the patient’s gut, accompanied by the complete disappearance of host CD4 cells.
After two years the patient had the CD4 count of a healthy adult of the same
age but no detectable HIV infection.
The case
was first reported at the 2008 Conference on Retroviruses and Opportunistic
Infections in Boston .
Berlin doctors also published a detailed case history in the New England Journal of Medicine in
February 2009 and have now published a follow-up report in the journal Blood saying, “It is reasonable
to conclude that cure of HIV infection has been achieved in this patient.”
The
success of the treatment could pave the way for the development of a cure for
HIV infection through the use of genetically engineered stem cells. Due to the
success of the treatment, scientists have been trying to coordinate efforts to
identify CCR5-delta 32 homozygosity donors to expand the supply of stem cells
carrying the genetic mutation, while several U.S. research groups have also
received funding to investigate techniques for engineering and introducing
these types of stem cells.
The road
to a cure hasn’t been easy for the patient, Timothy Ray Brown, a U.S. citizen who lives in Berlin . While dealing with the lengthy and
grueling treatment for leukemia he suffered two relapses and underwent two stem
transplants. He them developed a serious neurological disorder that led to a
bout of temporary blindness and memory problems. He is still undergoing
physiotherapy and speech therapy but now appears to be on the road to recovery.
However,
in an interview with German news magazine Stern this week when asked if it would have been better to
live with HIV than to have beaten it in this way he said, “Perhaps. Perhaps it
would have been better, but I don’t ask those sorts of questions anymore.”
