Description

Autism Physiology A Different Perspective Eugene S. Justus, D.O. Speedway Family Physician 1011 Main Street, Suite 110 Speedway, IN 46224

Indiana Osteopathic Association Convention, May 3, 2013

Objectives • Understand that Autism is epidemic • Support the perspective that Autism is a whole body disease. • Introduce the role of toxic injury, oxidative stress, and immune abnormalities in Autism Spectrum Disorders (ASD). • Support the concept that Autism is a dynamic encephalopathy as opposed to a fixed encephalopathy. 2

Conflict of Interest • Dr. Justus provides consultative services for children and families affected by Autism Spectrum Disorders at Speedway Family Physicians, Community Westview Physicians • Dr. Justus has a son with the diagnosis of Autism

3

Disclaimer • Any discussion of the treatment for Autism is “offlabel” except for the use of Risperidone and Aripiprazole for the treatment of irritability. • Irritability is not a core defect of Autism Spectrum Disorders (ASD).

Genetics

• Over 100 genetic abnormalities associated with ASD • 18 of 23 Chromosomes associated with ASD

California Autism Twin Study Conclusion Susceptibility to ASD has moderate genetic heritability and a substantial shared twin environmental component.

Better Counting? • UC Davis M.I.N.D. Institute study shows California's autism increase not due to better counting, diagnosis (2009) • “Autism incidence in California shows no sign yet of plateauing,” Hertz-Picciotto and Delwiche said in their study •

Better Counting? We investigated if shifts in the coding of qualifying conditions in the California Department of Developmental Services (DDS) have contributed to the increase in California children with autism observed in recent years. Qualifying condition codes for mental retardation (MR) and autism in DDS electronic files were compared to hard-copy records for samples of children

Contrary to expectations, we did not find evidence of a coding shift from "MR only" to "both MR and autism" or an increase in the proportion of children with born 1987, 1990, 1994, and 1997.

coded autism who lacked supportive diagnostic documentation in records (possible "misclassifications "). These results indicate that changes in DDS coding practices are unlikely to explain the increase in DDS clients with autism.

Toxic Injury A study by researchers at The University of Texas Health Science Center at San Antonio reveals a multiple-digits increase in the rate of autism for every 1,000 pounds of mercury released environmentally in Texas counties. The study does not prove causation of autism by mercury, researchers are quick to point out. The study compared mercury totals reported for 2001 in the 254 Texas counties to the rate of autism and special education services in nearly 1,200 Texas school districts. The districts, which range from urban to small metro to rural, enroll 4 million Texas children.

“The main finding is that for every 1,000 pounds of environmentally released mercury, we saw a 17 percent increase in autism rates,” said lead author Raymond F. Palmer, Ph.D., associate professor in the Health Science Center’s department of family and community medicine. Health & Place 12 (2006) 203–209

Toxic Injury and Genetic Predisposition Paraoxonase protects against organophosphates There is a gene PON 1 that codes for paroxonase.

Certain single nucleotide polymorphisms (SNP’s) can account for a 40 fold variability in activity PON1 purpose in Redox regulation and preventing oxidation of lipoproteins Chambers jJE. Proc Nat Acad. Sci. Sept 2nd 2008 105 (35) 12639-12640

Toxic Injury and Genetic Predisposition Paraoxonase gene variants are associated with autism in North America, but not Italy: possible regional specificity in gene-environment interactins • •

Immune Abnormalities • There is extensive cross talk between the immune system and then nervous system. • Neurotransmitters can modulate the immune responses. • The immune system can directly alter neurologic pathways which can affect mood and behaviors • Altered immune function has been associated with ASD for nearly 40 years. •

Immune Abnormalities

Immune Abnormalities Identification of Unique Gene Expression Profile in Children with Regressive Autism Spectrum Disorder (ASD) and Ileocolitis Authors demonstrated a profile for ASD that was different from Crohns Disease and Ulcerative Colitis, but with some overlap with both.

Oxidative Stress

Oxidative Stress An Open Label Trial of Methylcobalamin and Folinic Acid in Autistic children • Supplementation of methylcobalamin (Me-B12) and folinic acid for 3 months • Improved glutathione and precursors • Improved Vineland Behavioral Adaptive Behavioral Scales

Oxidative Stress Mitochondrial dysfunction in austism spectrum disorders: a systematic review and meta-analysis • Findings suggest children with ASD have a variety of mitochondrial dysfunctions (MD) • The prevalence of developmental regression, seizures, motor delay were higher with ASD/MD vs the general ASD population • The over all evidence supports MD is associated with ASD •

25

A Chronic Dynamic Encephalopathy • Case #1 in the 1943 Kanner paper. • Diagnosed with J.R.A. and treated with gold • Experienced remission of arthritis and autism symptoms • Earned a BS degree and lives independentaly.

26

A Chronic Dynamic Encephalopathy • The DSM IV criteria does preclude improvement • Transient improvement with fever and antibiotics

• Researchers have produced outcome studies and the notion of recovery • Reversal of abnormal behavior have been demonstrated in animal models •

Herbert, Autism , Oxidative Stress, Inflammation, and Immune Abnormalities. Ed by Chauhan, Chauhan, Brown. 27

Summary • Autism is epidemic • Autism is the result of the interaction of genetic predisposition, toxic injury, immune abnormalities and oxidative stress

• Autism is not a static, but dynamic encephalopathy subject whole body pathophysiology

So What??? You will see more and more of these individuals in your practices, even if you don’t do pediatrics. You can have a positive impact on their quality of life treating them osteopathicly . That is think about there underlying pathophysiology and address it.
