COLUMBUS, OH--(Marketwire -04/23/12)- With recent research finding that autism spectrum disorder (ASD) affects one in 88 children in the U.S., Battelle scientists have identified a low-cost urine test that potentially predicts the presence of this complex developmental disorder at an early age.
ASD, which is defined by behavioral characteristics, has been difficult for physicians to diagnose at an early age before these behaviors become more apparent (usually about two years of age or older).
The Battelle team of Drs. Nicholas Heyer and Diana Echeverria joined with Professor James Woods at the University of Washington's School of Public Health to evaluate the levels of porphyrins in the urine of children with ASD to determine if certain levels of specific porphyrins could predict ASD.
Identifying this link may have important clinical implications for diagnosis and treatment. The ability to detect porphyrins, a group of naturally occurring organic compounds, in a simple urine test allows for a rapid, low-cost and widely used screening test for identifying young children at a high risk for ASD.
Woods is a world expert in porphyrins. He collected urine samples from a study group of children with ASD and age-matched controls. Woods published his initial results indicating higher levels of porphyrins in children with ASD.
Subsequently, Heyer, a senior health research scientist in epidemiology at Battelle, led the analyses evaluating porphyrins as a potential biomarker of autism. His analyses indicated that levels of specific porphyrins were strong predictors of ASD and could distinguish up to one-third of the children with ASD without identifying any of the control children.
"This is significant because it means children may be diagnosed with ASD at an earlier age and can thus receive treatment sooner. Early treatment can lead to a better quality of life for children with ASD," Heyer said.
The findings were published in this month's edition of Autism Research, and coincide with Autism Awareness Month. The full article can be found http://onlinelibrary.wiley.com/doi/10.1002/aur.236/full.
"The world-class work performed by Drs. Heyer and Echeverria in collaboration with Professor Woods represent Battelle's capacity and resolve to advance the diagnosis and treatment of health threats worldwide," said Barbara Kunz, president of Battelle Health and Life Sciences. "Their innovative contributions reflect Battelle's expertise in child and maternal health, as well as our proficiency in solving global health challenges."
