Researchers have found a vaccine that may help autistic children.
A first-ever vaccine created by University of Guelph researchers for gut bacteria common in autistic children may also help control some autism symptoms.
They developed a carbohydrate-based vaccine against the gut bugClostridium bolteae.
C. bolteae is known to play a role in gastrointestinal disorders, and it often shows up in higher numbers in the GI tracts of autistic children than in those of healthy kids.
More than 90 per cent of children with autism spectrum disorders suffer from chronic, severe gastrointestinal symptoms. Of those, about 75 per cent suffer from diarrhea, according to current literature.
“Little is known about the factors that predispose autistic children to C. bolteae,” said Monteiro. Although most infections are handled by some antibiotics, he said, a vaccine would improve current treatment.
“This is the first vaccine designed to control constipation and diarrhea caused by C. bolteae and perhaps control autism-related symptoms associated with this microbe,” he said.
Autism cases have increased almost sixfold over the past 20 years, and scientists don’t know why. Although many experts point to environmental factors, others have focused on the human gut.
