Children with neurological and behavioral problems are commonly given the diagnosis of Autistic Spectrum Disorders
(ASD), which is a highly heterogeneous group of patients manifesting autistic-like behaviors. A vast majority but not all ASD
children have classic or typical autism. In that regard, we recently identified an autoimmune subset of autism and referred to it as
?Autoimmune Autistic Disorder (AAD).? In this report, we describe laboratory studies for the identification and characterization
Subjects in the study were autistic children and normal healthy children. Blood samples of these children and cerebrospinal
fluid (CSF) sample of some children were analyzed. These specimens were analyzed autoimmune markers that included
brain autoantibodies, pro-inflammatory cytokines and virus/vaccine serology. Laboratory methods included enzyme-linked
immunosobent assay (ELISA) and protein immunoblotting assay.
We found experimental evidence for the presence of autoimmune markers in children with autism but not in healthy children.
First, autistic children harbored brain-specific autoantibodies [e.g. antibodies to myelin basic protein (anti-MBP) and antibodies
to caudate nucleus (anti-CN)]. Secondly, autistic children had elevated levels of pro-inflammatory cytokines (e.g. interferongamma
and interleukin-12), acute-phase protein (e.g. C-reactive protein) and S-100 protein. Thirdly, autistic children harbored
elevated levels of antibodies to measles virus (but not CMV, EBV, HHV-6, mumps or rubella virus) and measles/mumps/rubella
(MMR) vaccine (but not Hepatitis B, DT or DPT). CSF samples of some autistic children were also positive for antibodies to
brain antigens and measles virus. Of clinical importance to autoimmune pathogenesis, we found a positive correlation between
brain autoantibodies (anti-MBP) and virus serology (anti-measles virus). Collectively, these laboratory findings provide scientific
evidence in support of an autoimmune mechanism of pathogenesis of autism. This mechanism was found in a vast majority
of children with autism - an autoimmune subset - henceforth referred to as ?Autoimmune Autistic Disorder (AAD)?. Since
health conditions involving autoimmunity are commonly regarded as autoimmune diseases and treated medically, we suggest
that autism or AAD be considered as a medical condition and be treated with immune modulation therapy.
