Autism Gastro Problems May Be Linked to Gut Bacteria

TUESDAY, Jan. 10 (HealthDay News) — Children with autism have
bacteria in their gut that is different from the bacteria seen in kids who
do not have the disorder, researchers have found.

In their report, published Jan. 10 in the online journal mBio,
researchers from the Mailman School of Public Health at Columbia
University in New York City suggested that this finding could help explain
the link between autism and gastrointestinal problems, such as
inflammation.

The study authors added, however, it is still unclear if these
differences are a cause of autism or a result of the condition.

“The relationship between different microorganisms and the host and the
outcomes for disease and development is an exciting issue,” the study’s
editor, Christine Biron, a professor of medical science at Brown
University, said in an American Society for Microbiology news release.
“This paper is important because it starts to advance the question of how
the resident microbes interact with a disorder that is poorly
understood.”

The researchers found a relatively large amount of Sutterella
bacteria in 12 out of 23 tissue samples taken from the guts of children
with autism. In contrast, they did not find this type of bacteria in any
samples taken from children without autism who were studied for
comparison.

Sutterella has been associated with gastrointestinal diseases
below the diaphragm, and whether it’s a pathogen or not is still not
clear,” explained a reviewer of the research, Jorge Benach, chairman of
the microbiology department at Stony Brook University. “It is not a very
well-known bacterium,” he pointed out in the news release.

The findings are significant because digestive complications can be
very serious in kids with autism, contributing to their behavioral
problems, the study authors noted.

The study results are also more definitive than previous studies that
used stool samples, because tissue samples surgically removed from the gut
are more reflective of the bacteria found in the children’s intestinal
walls.

While the study uncovered an association between the bacteria and
autism, it did not prove a cause-and-effect relationship, so more research
is needed to explore the link between Sutterella and
gastrointestinal problems in autism, the researchers said.
