A Study Found That Children Diagnosed With ASD Had A Food Allergy

"We don't know which comes first, food allergy or ASD," said Bao

Children with autism spectrum disorder (ASD) are more than twice as likely to suffer from a food allergy than children who do not have ASD, a new study suggests.

The study found that, among the participants, 11.25 per cent of children reportedly diagnosed with ASD had a food allergy, significantly higher than the 4.25 per cent of children who were not diagnosed with ASD and had a food allergy.

“It is possible that the immunologic disruptions may have processes beginning early in life, which then influence brain development and social functioning, leading to the development of ASD,” said co-author Wei Bao, Assistant Professor at the University of Iowa, in the US.

The finding, published in the journal JAMA Network Open, adds to a growing body of research that suggests immunological dysfunction as a possible risk factor for the development of ASD.

For the study, the researchers analysed the health information of nearly 200,000 children in the US. They were aged between three to 17 and the data were gathered between 1997 and 2016.

The study also found that 18.73 per cent of children with ASD suffered from respiratory allergies, while 12.08 per cent of children without ASD had such allergies; and 16.81 per cent of children with ASD had skin allergies, well above the 9.84 per cent of children without ASD.

“This indicates there could be a shared mechanism linking different types of allergic conditions to ASD,” Bao noted.

The researcher said that the study could not determine the causality of this relationship given its observational nature.

But previous studies have suggested possible links — increased production of antibodies, immune system overreactions causing impaired brain function, neurodevelopmental abnormalities, and alterations in the gut biome, the researchers said.

“We don’t know which comes first, food allergy or ASD,” said Bao, adding that another longitudinal follow-up study of children since birth would be needed to establish temporality. (IANS)

Two-Wave U.S. Flu Season is Now the Longest in Ten Years

Still, this flu season is not nearly as bad as last winter's 19-week season, the deadliest in at least four decades. An estimated 80,000 Americans died of flu and its complications last season.

Three months ago, this flu season was shaping up to be short and mild in the U.S. But a surprising second viral wave has made it the longest in 10 years.

This flu season has been officially going for 21 weeks, according to reports collected through last week and released Friday by the Centers for Disease Control and Prevention. That makes it among the longest seen since the government started tracking flu season duration more than 20 years ago.

Some experts likened the unusual double waves to having two different flu seasons compressed, back-to-back, into one.

“I don’t remember a season like this,” said Dr. Arnold Monto, a University of Michigan researcher who had been studying respiratory illnesses for more than 50 years.

The previous longest recent flu season was 20 weeks, which occurred in 2014-2015.

Flu can cause a miserable, relatively mild illness in many people and a more severe illness in others. Young children and the elderly are at greatest risk from flu and its complications. Flu vaccinations are recommended annually for all but the very young.

The current season began the week of Thanksgiving, a typical start time. At the beginning, most illnesses were caused by a flu strain that tends not to cause as many hospitalizations and which is more easily controlled by vaccines.

But in mid-February, a nastier strain started causing more illnesses and driving up hospitalizations.

Not helping matters: The harsher bug is not well matched to the vaccine, said the CDC’s Lynnette Brammer, who oversees flu tracking.

The CDC is estimating that flu-related deaths this season in the range of 35,000 to 55,000.

More good news: Brammer said that although the virus is notoriously unpredictable, signs suggest this flu season should be over soon.

“It’s on the verge” of being over, she said. “If nothing changes.” (VOA)
