Gluten-sensitivity in Autism Different than Celiac Disease

Celiac.com 07/24/2013 - Gastrointestinal symptoms are a common feature in children with autism, drawing attention to a potential association with celiac disease or gluten sensitivity.

Photo: CC--Bryce EdwardsSo far, studies of the immune response to gluten in autistic individuals, along with its association with celiac disease have produced inconsistent data.

A team of researchers recently set out to assess immune reactivity to gluten in children diagnosed with autism according to strict criteria, and to evaluate the potential link between autism and celiac disease.

The research team included Nga M. Lau, Peter H. R. Green, Annette K. Taylor, Dan Hellberg, Mary Ajamian, Caroline Z. Tan, Barry E. Kosofsky, Joseph J. Higgins, Anjali M. Rajadhyaksha, and Armin Alaedini.

For their study, the team assessed 37 children (with or without gastrointestinal symptoms) diagnosed with autism according to both the Autism Diagnostic Observation Schedule (ADOS) and the Autism Diagnostic Interview, Revised (ADI-R), 27 unaffected siblings, and 76 age-matched healthy controls.

They then tested blood specimens for antibodies to native gliadin, deamidated gliadin, and transglutaminase 2 (TG2). They then genotyped all children with positive antibody tests for celiac disease associated HLA-DQ2 and -DQ8 alleles.

The team found that children with autism had substantially higher levels of IgG antibodies compared with unrelated healthy controls (p<0.01). The IgG levels were also higher compared to the unaffected siblings, but were not statistically significant. Autistic children with gastrointestinal symptoms showed significantly greater IgG anti-gliadin antibody response, compared to those without them (p<0.01). All groups showed similar IgA response to gliadin across groups.

Both study subjects and control subjects ahd similar levels of celiac disease-specific serologic markers, i.e., antibodies to deamidated gliadin and TG2. The researchers found no association between increased anti-gliadin antibody and presence of HLA-DQ2 and/or -DQ8.

Some children with autism do show a type of increased immune reactivity to gluten which appears to be different from celiac disease.

The increased anti-gliadin antibody response and its association with GI symptoms suggests that these children may suffer from immunologic and/or intestinal permeability abnormalities.

It is heartening to know that research like this is occurring. I believe that autism is also about peptides released from gluten and casein. These can be measured in urine samples.

MelissaNZ, Has your daughter been checked for vitamin deficiencies??? Vitamin D deficiency symptoms include urinary incontinence, oral candidiasis (thrush), skin rashes, bumps on the backs of arms, joint pain, distended stomach and short stature. Bones can't grow much without vitamin D. Vitamin D deficiency causes delayed gastric emptying (food doesn't move through the gastrointestinal tract at a normal speed and the intestines bloat) which explains your daughter's delayed reaction to the cake. Vitamin A deficiency is also a cause of bumps on the back of the arms. Vitamin A deficiency causes vision problems. Vitamin A and D are both fat soluble vitamins. Absorption of fats is a problem for Celiacs. So is absorption of B vitamins and important minerals. B Complex vitamins are water soluble and must be replenished every day. Skin rashes are associated with several B vitamins like niacin (B3), B12, and thiamine (B1). I went through a period of severe malnutrition prior to diagnosis. It was not a pleasant experience. I had symptoms similar to your daughter's, including the incontinence, which resolved on vitamin D supplementation. Please, please have your daughter tested for vitamin D deficiency. And have her B vitamins checked as well. Celiac Disease causes malabsorption. Malabsorption causes deficiency diseases. Newly diagnosed Celiacs need to be checked for deficiencies. I hope this helps.

I will try to make my long story short, I have been searching my whole life for a diagnosis, I have seen pretty much every doctor possible I even went through a spinal tap recently because they thought I had multiple sclerosis, when I was younger I was always throwing up and having stomach problems, a couple hospital visits they thought I had appendicitis, I started having a neurological symptoms as well as anxiety and depression, The fatigue was just over bearing, I was having numbness and tingling and muscle spasms all the time eventually started having seizures, which kind of cycled through and stop happening after a couple months, and then it dawned upon me my brother has celiac pretty severely, my grandmother also has celiac, my dad does as well, I don't know why I never thought that it could be my issue, for the last week I have Been gluten-free and steering clear of cross-contamination, my dizziness is improved my fatigue is improved as well as rashes I was getting on my arms and sides, I have no more muscle jerks or spasms, The problem is I have horrible insurance and I cannot afford testing, so I am at least trying to do it an home blood test, I know it's not very accurate on telling me if I have celiac or not, But the thought I may never know for sure if I have it is very daunting. My family keeps telling me you don't need to spend thousands of dollars to have a doctor tell you you can't eat something you already know you can't. Just was wondering if anybody else has been in my position and seeing if anybody has a vi just was wondering if anybody else has been in my position and seeing if anybody has advice, I don't want to be known as one of those people who believe they have something and people with the disease frown upon them it's a very scary thing to think about.

...ON a side note this is quite easy, you can make your own out of any gluten-free Bread mix, I recently started using a coconut flour blend for this.......Most often people associate caraway with Rye Bread so you just add caraway seeds to the dough and a bit more vinegar to sour it a tad and BAM gluten-free Rye Bread knock off. I think Authentic Foods even has a additive to put in bread mixes to make it taste like Rye Bread....Or you can buy it preamade, I have issues with all the other ingredients but as for one of the best gluten-free Breads out the Canyon House makes a Rye like bread https://canyonglutenfree.com/buy-gluten-free-bread-products/Gluten-Free-Rye-Deli-Sandwich-Bread.html

Took me less than a minute, although why did they need our addy and phone?

As mentioned before you said she had rashes, have they checked if that is DH? That is a positive sign of celiac and those with the DH manifestation can have problems getting a postive with the gut biopsy. Here are some links. https://celiac.org/celiac-disease/understanding-celiac-disease-2/dermatitis-herpetiformis/ https://www.gluten.org/resources/getting-started/dermatitus-herpetiformis/ Please read up on this. She can get the rash tested for the disease if it is DH.
