The Gluten File

Dietary intervention has proven effective for many children with Autism, in both gastrointestinal and behavioral symptoms. Although not all children will show improvement, the reports of thousands of children who have improved remarkably can no longer be ignored by mainstream medicine.

There may be two different problems at work when it comes to autism and gluten or casein: the autoimmune problem and the gluten/casein peptide problem.  There does seem to be some increase or overlap in those families with history of celiac disease or other autoimmune disease.

Immune system of a subgroup of ASDs is triggered by gluten and casein; this could be related either to AGA, DPG, and Casein IgG elevated production or to impaired intestinal barrier function.

CONCLUSIONS AND RELEVANCE Although this study found no association between CD or inflammation and earlier ASDs, there was a markedly increased risk of ASDs in individuals with normal mucosa but a positive CD serologic test result.

A subset of children with autism displays increased immune reactivity to gluten, the mechanism of which appears to be distinct from that in celiac disease. The increased anti-gliadin antibody response and its association with GI symptoms points to a potential mechanism involving immunologic and/or intestinal permeability abnormalities in affected children.

RESULTS:: A high percentage of abnormal IPT values were found among patients with autism (36.7%) and their relatives (21.2%) compared with normal subjects (4.8%). Patients with autism on a reported gluten-casein-free diet had significantly lower IPT values compared with those who were on an unrestricted diet and controls. Gastrointestinal symptoms were present in 46.7% of children with autism: constipation (45.5%), diarrhoea (34.1%), and others (alternating diarrhoea/constipation, abdominal pain, etc: 15.9%). FC was elevated in 24.4% of patients with autism and in 11.6% of their relatives; it was not, however, correlated with abnormal IPT values. CONCLUSIONS:: The results obtained support the leaky gut hypothesis and indicate that measuring IPT could help to identify a subgroup of patients with autism who could benefit from a gluten-free diet. The IPT alterations found in first-degree relatives suggest the presence of an intestinal (tight-junction linked) hereditary factor in the families of subjects with autism.

Gastrointestinal symptoms are described in 9-54% of autistic children, among which most common are: constipation, diarrhea and abdominal distension. The gastro-intestinal abnormalities reported in autism include: inflammation (esophagitis, gastritis, duodenitis, enterocolitis) with or without autoimmunity, lymphoid nodular hyperplasia, increased intestinal permeability, low activities of disaccharidase enzymes, impairment of detoxification (e.g. defective sulfation of ingested phenolic amines), dysbiosis with bacterial overgrowth, food intolerance or exorphin intoxication (by opioid derived from casein and gluten). A beneficial effect of dietary intervention on behavior and cognition of some autistic children indicates a functional relationship between the alimentary tract and the central nervous system.

"However this is of particular interest given the recent publication by Eaton and colleagues in the July 6 online edition of Pediatrics demonstrating a greater than 3-fold risk of autism in children born to mothers diagnosed with celiac disease. This brings some credibility to the anecdotal reports of gastrointestinal and behavioral improvements in children with autism spectrum disorders and/or verbal apraxia when eliminating gluten from their diets."

Conclusions: Associations regarding family history of type 1 diabetes and infantile autism and maternal history of rheumatoid arthritis and ASDs were confirmed from previous studies. A significant association between maternal history of celiac disease and ASDs was observed for the first time. The observed associations between familial autoimmunity and ASDs/infantile autism are probably attributable to a combination of a common genetic background and a possible prenatal antibody exposure or alteration in fetal environment during pregnancy.

A case is presented of a 5-year-old boy diagnosed with severe autism at a specialty clinic for autistic spectrum disorders. After initial investigation suggested underlying celiac disease and varied nutrient deficiencies, a gluten-free diet was instituted along with dietary and supplemental measures to secure nutritional sufficiency. The patient's gastrointestinal symptoms rapidly resolved, and signs and symptoms suggestive of autism progressively abated. This case is an example of a common malabsorption syndrome associated with central nervous system dysfunction and suggests that in some contexts, nutritional deficiency may be a determinant of developmental delay. It is recommended that all children with neurodevelopmental problems be assessed for nutritional deficiency and malabsorption syndromes.

Growing evidence suggests that autoantibodies to neuronal or endothelial targets in psychiatric disorders exist and may be pathogenic. This review describes and discusses the possible role of autoantibodies related to the psychiatric manifestations in autoimmune diseases, autoantibodies related to the psychiatric disorders present in post-streptococcal diseases, celiac disease, chronic fatigue syndrome and substance abuse, and autoantibodies related to schizophrenia and autism, disorders now considered of autoimmune origin.

We conclude that a subgroup of patients with autism produce antibodies against Purkinje cells and gliadin peptides, which may be responsible for some of the neurological symptoms in autism.
