Autistic children with gastrointestinal symptoms have an imbalance in their immune response that affects behavior and quality of life.
Differential immune responses and microbiota profiles in children with autism spectrum disorders and co-morbid gastrointestinal symptoms
Rose DR, Yang H, Serena G, Sturgeon C, Ma B, Careaga M, Hughes HK, Angkustsiri K, Rose M, Hertz-Picciotto I, Van de Water J, Hansen RL, Ravel J, Fasano A, Ashwood P. Brain, Behavior, and Immunity. 2018;70:354-368.
Children with autism spectrum disorder (ASD) and concurrent gastrointestinal (GI) symptoms have a more imbalanced immune response, a more disturbed gut microbiome and worse behavioral outcomes (such as irritability, agitation, social withdrawal, lethargy, hyperactivity and noncompliance) than ASD children without GI symptoms. The study additionally looked at typically developing children with and without GI symptoms and found that ASD+GI children stood out compared to those two groups as well. Children with ASD plus GI symptoms may have a “propensity” toward leaky gut that contributes to their other symptoms and clinical outcomes.
Israeli and Italian researchers demonstrate that exposure to aluminum in vaccines can lead to autoimmune and brain dysfunction.
Autoimmune/inflammatory syndrome induced by adjuvants (ASIA) 2013: Unveiling the pathogenic, clinical and diagnostic aspects
Perricone C, Colafrancesco S, Mazor RD, Soriano A, Agmon-Levin N, Shoenfeld Y. Journal of Autoimmunity. 2013;47:1-16.
Environmental factors play a critical role in the induction of autoimmunity, with an interplay between genetic susceptibility and environment. Several neurologic demyelinating diseases have been reported following vaccination, notably Guillain-Barre syndrome (GBS) and acute disseminated encephalomyelitis (ADEM) (an inflammatory disease of the central nervous system). A number of the most common vaccines appear to have some involvement with autoimmunity.
