Guest guest Posted April 13, 2005 Report Share Posted April 13, 2005 http://tinyurl.com/6lnev April 12, 2005 WASHINGTON (Reuters) - Antibodies that attack the protein believed responsible for Alzheimer's disease may offer a new way to treat the brain-destroying illness, U.S. researchers reported on Tuesday. The infusion of antibodies seemed to be safe and may have delayed or even halted progression of the fatal disease in Alzheimer patients, the researchers said. But the trial of immunoglobulin, or IVIg, therapy was done in just eight patients and it is too early to know much about its promise, the team at New York-Presbyterian Hospital/Weill Cornell Medical Center cautioned. " If these results are confirmed in larger, controlled trials, we might have a safe Alzheimer's treatment capable of clearing the amyloid protein away, " Dr. Marc Weksler, who helped lead the study, said in a statement. In the Phase I safety trial, eight Alzheimer's patients were treated with IVIg for six months and then tested for decline in their mental function. Cognitive function stopped worsening in seven patients tested so far and has improved in six, the researchers told a meeting of the American Academy of Neurology in Miami. The antibodies target beta-amyloid, a protein that is a key feature of the brain-clogging plaques and tangles that characterize Alzheimer's. It seems to kill nearby brain cells, robbing patients of memories and eventually of all ability to function and care for themselves. Previous studies had shown that antibodies, which are immune system proteins that recognize and latch onto germs and abnormal cells, can also pull beta-amyloid out of the nervous system. Using infusions of antibodies from blood is called passive immunization and has been used to fight diseases such as hepatitis. " Immune therapy for Alzheimer's disease has shown tremendous promise in the laboratory but has been difficult to translate into clinical practice, " said Dr. Norman Relkin of Weill Cornell Medical College. Other efforts to make a vaccine against Alzheimer's have been troubled by complications -- one vaccine caused fatal encephalitis, a swelling of the brain, for instance. But IVIg has been approved for decades for use in treating immune disorders. It turns out it contains elements specific for beta- amyloid.

Guest guest Posted April 13, 2005 Report Share Posted April 13, 2005 These are designer IgGs- specifically targeted, and somehow the population's controlled - much more so than the last Alzheimer clinical trial where the IgG attacked the amyloid so fiercely that 2 died from brain swelling - I hate those general terms - brain swelling - what the heck does that mean-? (herx?) I must be missing something... So do they know for sure there isn't bacteria inside those plaques? Did they even LOOK?

Guest guest Posted April 14, 2005 Report Share Posted April 14, 2005 Thank you so much for this information. I have severely deficient IgG and am waiting for a script of gamma globulin this week. I had to change doctors as the duc I was seeing and the one monitoring my IgG promised to prescribe it once he saw how low my blood levels went during the period that he wihtheld my IVIG. I'm so tired of these doctors who always won't beleive recent but other ordered blood tests and want to see it for themselves just HOW LOW CAN HER IgG GO DOWN !!!! It is just the pits to have three rare diseases becuase if I get a handle on one, then another will flare. I say , But hey, duc, they are all connected. like the thigh bone connected to the knee bone. But they shake their head and say " Oh, no " they are completely separarte and you have to see another specialist for that problem. I am no longer a person but modern medicine has divided me into eight or so equal body parts. Its funny though, just before I sat down at the computer I was reading the physicians desk reference on intramuscular gamma and having a slight panic moment on just this issue. Can't worry, but wondering if any of these other diseases I'm now saddled with came from some latent but infected gamma?

Guest guest Posted April 14, 2005 Report Share Posted April 14, 2005 Peg, I've used IVIG for over two yrs now, and I can safely say it has given me my life back--gainfully employed again, working out at the gym, ect. Orginal dx was borrelia infection, other TBD's, mycoplasmas, viruses, ect. Savy doctor checked immune status, and my total IgG was 18!!!!! I also pursued testing with an Immuniologist--which turned up that this was much more than just immune supression from chronic infections. Barb Peck, the " Brain Herx " that you mentioned is called " Aseptic Meningitis " , and it is very surprising that they(in the mentioned study) did not use precautionary measures to protect the participates from having these problems Also, no one must have checked IgA status, since many who are absent, or near absent with regards to production of IgA---can go into anaphylatic shock when recieving IVIG with high levels of IgA There are brands available with low levels of IgA Best,CELIENE - In infections , " Peg " <lanelle@h...> wrote: > > Thank you so much for this information.
