POZ - Treatment News : Crystal Meth Accelerates HIV Reproduction

Crystal methamphetamine (crystal meth) speeds up HIV replication in both test tube studies and in specially bred HIV-infected mice, according to a study published in AIDS Research and Human Retroviruses.

The connection between crystal meth use and HIV transmission has been well established by researchers—people using the drug are more likely to become infected with the virus, or transmit it onward. Studies have also documented more substantial brain damage and cognitive impairment among HIV-positive meth users, compared with people living with HIV not using the drug.

Whether crystal meth speeds up HIV replication—higher viral loads and more rapid CD4 cell loss—in people infected with the virus has not been determined, though some test tube data suggest that it might.

To look at crystal meth’s potential to accelerate HIV disease progression, Aviva Joseph, PhD, at the Albert Einstein College of Medicine, in Bronx, New York, and her colleagues looked at HIV reproduction both in a test tube model and in mice bred to carry human immune systems that can be infected with HIV.

In the test tube studies, Joseph’s team found that adding crystal meth to immune cells significantly increased HIV replication, particularly in CD4 cells and in a type of cell known as a monocyte. These findings are synonymous with those of other research teams.

Joseph and her colleagues also saw increased HIV replication in the mouse model. Specifically, when crystal meth was given to HIV-infected mice, it activated a portion of the HIV genetic code known as the long terminal repeat (LPR), which prompted the cells to release a protein that can stimulate tumor necrosis factor alpha, a protein tied to more rapid HIV disease progression.

The authors concede that further studies are necessary. However, they also conclude that these data support the theory that regular crystal meth use might hasten the progression of HIV disease.

Obviously that poster was looking to cause an "uproar" and is attention seeking. Meth., even if not HIV poz, destroys the body inside out...lets add the addiction issue and resorting to all kinds of activities - illegal - to score the next hit so it also becomes a community/social problem.

You've got to be kidding me, right? You think meth is a part of a "holistic" lifestyle? Either you're a writer for The Onion or in serious need of a mirror to understand what denialism is. Idiot.

Omg my gosh! I can't believe AIDSMEDS supports DENIALIST research. This is obviously lies funded by DENIALISTS. I do meth all the time, so long as I take my meds there is no problem. I consider meth to part of a holistic lifestyle. Diet, exercise, ARVs, and meth.
