Fasano’s Spectrum of Gluten-related disorders

March 11, 2012 Leave a comment

In February 2012, Alessio Fasano published a new study – Spectrum of gluten-related disorders: consensus on new nomenclature and classification – in it he and his team lay out the broad range of gluten related disorders, including Celiac(CD)/Autoimmune and Wheat Allergy (WA)/Allergic, but not autoimmune.  He also discusses at some length what he calls Gluten Sensitivity (GS) “The symptoms in GS may resemble those associated with CD but with a prevalence of extraintestinal symptoms, such as behavioral changes (depression, foggy-mind, headache), abdominal pain/diarrhea,  eczema, bone or joint pain, muscle cramps, leg numbness, weight loss, anemia and chronic fatigue.”

Conclusions
“It is now becoming apparent that reactions to gluten are not limited to CD, rather we now appreciate the existence of a spectrum of gluten-related disorders. The high frequency and wide range of adverse reactions to gluten raise the question as to why this dietary protein is toxic for so many individuals in the world. One possible explanation is that the selection of wheat varieties with higher gluten content has been a continuous process during the last 10,000 years, with changes dictated more by technological rather than nutritional reasons.
Wheat varieties grown for thousands of years and mostly used for human nutrition up to the Middle Ages contain less quantities of the highly toxic 33-mer gluten peptide. Apparently the human organism is still largely vulnerable to the toxic effects of this protein complex, particularly due to a lack of adequate adaptation of the gastrointestinal and immunological responses.
Additionally, gluten is one of the most abundant and diffusely spread dietary components for most populations, particularly those of European origin.  All individuals, even those with a low degree of risk, are therefore susceptible to some form of gluten reaction during their life span. Therefore, it is not surprising that during the past 50 years we have witnessed an ‘epidemic’ of CD and the surging of new gluten-related disorders, including the most recently described GS.”

The point is that gluten is toxic…even if you don’t have Celiac Disease.  Fasano notes that Gluten Sensitivity may be at play in a wide variety of disorders including: eczema, Autism & Autism Spectrum Disorders, Neuropsychiatric disorders/Schizophrenia, IBS, Diabetes, MS and Dimentia to name a few.

Glutens Impact Goes Beyond Celiac – An interview with Dr. Fasano

January 12, 2012 2 comments

Here is a blog post by Tender Foodie that includes a recent interview with Dr. Alessio Fasano and thought it was important enough to link to. I hope he doesn’t mind. What is critical here is that gluten has impacts on leaky-gut beyond celiac disease. If you have an autoimmune disease, grains are central to the problem.

How many forms of gluten reactions are there?
Dr. Fasano:  There are 3 forms.  Celiac Disease, and Gluten Sensitivity, and Gluten/Wheat Allergy – and there are four different types of wheat allergy that all behave differently.

What is behind all of these reactions?
Dr Fasano:  Gliadin.  Gliadin is one of the proteins found in gluten.  When someone has a reaction, it’s because gliadin cross talks with our cells, causes confusion, and as a result, causes the small intestine to leak.  Gliadin is a strange protein that our enzymes can’t break down from the amino acids (glutamine and proline) into elements small enough for us to digest.  Our enzymes can only break down the gliadin into peptides.  Peptides are too large to be absorbed properly through the small intestine.  Our intestinal walls or gates, then, have to separate in order to let the larger peptide through.  The immune system sees the peptide as an enemy and begins to attack.  The difference is that in a normal person, the intestinal walls close back up, the small intestine becomes normal again, and the peptides remain in the intestinal tract and are simply excreted before the immune system notices them.   In a person who reacts to  gluten, the walls stay open as long as you are consuming gluten.  How your body reacts (with a gluten sensitivity, wheat allergy or Celiac Disease) depends upon how long the gates stay open, the number of “enemies” let through and the number of soldiers that our immune system sends to defend our bodies.  For someone with Celiac Disease, the soldiers get confused and start shooting at the intestinal walls.

 That sounds like everyone is gluten intolerant in some way.  Is that true?  Everyone?
Dr Fasano: Yes.  No one can properly digest gluten.  We do not have the enzymes to break it down.  It all depends upon how well our intestinal walls close after we ingest it and how our immune system reacts to it.
