"Immune system, blood altered in autism"

"Immune system, blood altered in autism" dated 7 May 2006 from the Pak
Tribune at http://paktribune.com/news/index.php?id=142921

"Children with autism show different immune system responses from children
without the condition, and these might be measured in the blood for a
possible screening test, U.S. researchers reported on Thursday. Two studies
presented to a conference on autism help support other research that
suggests subtle differences in the immune function of children with autism.
Autism is a brain disorder usually seen as children become toddlers.
Affecting an estimated two to five out of every 1,000 children, autism has a
spectrum of symptoms that include difficulty with social interaction and
repetitive behaviors. No one knows what causes autism, although experts
have largely rejected purported links with childhood vaccines. Scientists
at the 4th International Meeting for Autism Research in Boston presented
studies looking at the blood of children with autism. Judy Van de Water of
the University of California, Davis, and colleagues separated immune cells
from 30 children with autism and 26 non-autistic children aged 2 to 5. They
mixed in toxins and bacteria. In response to bacteria, the researchers saw
lower levels of immune signaling proteins called cytokines in the group with
autism. These children also had irregular responses to a plant protein, but
not to other toxins or to a measles, mumps and rubella vaccine.
"Understanding the biology of autism is crucial to developing better ways to
diagnose and treat it," Van de Water said in a statement. A second team at
the same center took blood samples from 70 children aged 4 to 6 with autism
and from 35 other children. The children with autism had 20 percent more
immune system cells called B cells and 40 percent more natural killer cells.
There also seemed to be differences in other proteins in the blood, although
the researchers are still sifting through the data. "From these results we
think it is highly likely that there are differences we can detect in blood
samples that will be predictive of the disorder, though we are still some
years away from having an actual diagnostic blood test for autism," said
researcher David Amaral, who led the study. ..."

Looks like they are a little behind the times in Pakistan . Not that there's anything wrong with the research, but it's from last year's IMFAR conference on May 5, 2005.

The study mentioned is on page 50 of this pdf file.

What does this mean, exactly? Is this why my son almost never gets sick? :?

Didn't realize it was so old, the date on my email was May 7, 2006. That same date is a the top of the article. Hmmm. Strange.
