New finding could yield urine test for autism
(AFP)  1 day ago

PARIS  A newly discovered chemical fingerprint could yield a simple
urine test to determine if a child has autism, according to a study
released on Thursday.

Autism and related disorders affect up to six or seven out of every
1,000 individuals.

Symptoms are life-long and can vary widely, but often include impaired
social skills, repetitive behaviours, difficulty in expressing one's
emotions, and an aversion to physical intimacy. There is no known

The factors leading to autism are generally present at birth, but the
disorder is difficult to diagnose as it can be confused with other
behaviour-related problems.

At present, children are assessed through a lengthy process that tests
social interaction, communication and imaginative skills.

A confirmed diagnosis is rare before the age of 18 months, and most
often occurs much later.

A chemical marker would allow early diagnosis and could prove hugely
helpful in getting a head start on treatment, the researchers said.

"Giving therapy to children with autism when they are very young can
make a huge difference to their progress," said lead researcher Jeremy
Nicholson, a professor at Imperial College London.

"A urine test might enable professionals to quickly identify children
with autism to help them early on," he said in a statement.

Such a test, he cautioned, would probably take several years to

Surprisingly, the key to the chemical fingerprint is found in the
digestive tract.

People with autism typically suffer from gastrointestinal problems
stemming from a different bacterial makeup in the gut.

The study, published in the Journal of Proteome Research, found that
the way in which the body metabolises these unique intestinal flora
creates a chemical signature in urine.
