Jon Poling: Mitochondrial Dysfunction Not Rare In Autism

Posted Aug 24 2008 7:08pm
Dr. Poling suggesting medically defining "Mitochondrial Autism". I have been calling it "Poling Syndrome".



No matter what it is called, "what Hannah has" has been determined by HHS to be a vaccine injury. It is time for the medical community to define it, find what the percentage of kids with it are, screen for it and catch it before it descends into the "symptoms of Autism".



And if the medical authorities won't hear it from me, hear it from Jon Poling:



"As a neurologist, I have cared for those afflicted with SSPE (a rare but dreaded neurological complication of measles), paralytic polio and tetanus. If these serious vaccine-preventable diseases again become commonplace, the fault will rest solely on the shoulders of public health leaders and policymakers who have failed to heed the writing on the wall (scribbled by my 9-year old daughter)."



Reform the vaccine schedule before everyone abandons it.



Father: Child's case shifts autism debate

By Jon S. Poling

For the Journal-Constitution

Published on: 04/11/08



Autism in the U.S. has reached epidemic levels, at 1 in 150 children. Dr. Julie Gerberding, director of the Centers for Disease Control and Prevention, has recently upgraded autism to "an urgent health threat." The most contentious issue of the autism debate is the link to routine childhood vaccines. My daughter's case, Hannah Poling v. U.S. Department of Health and Human Services, has changed this debate forever. Hannah has pointed us in a new and promising direction —- the mitochondria.



On Nov. 9, 2007, HHS medical experts conceded through the Department of Justice that Hannah's autism was triggered by nine childhood vaccinations administered when she was 19 months of age. This concession was granted without any courtroom proceedings or expert testimony, effectively preventing any public hearing discussing what happened to Hannah and why. Contrary to some reports, the Special Masters, "judges" who preside over the "vaccine court," did not issue a decision.



Four months later, on March 6, with trepidation my wife, Terry, and I stepped forward to announce this news —- providing hope and awareness to other families. The HHS expert documents that led to this concession and accompanying court documents remain sealed, though our family has already permitted release of Hannah's records to those representing the almost 5, 000 other autistic children awaiting their day in vaccine court.



Mitochondria key



To understand Hannah's case, it is important to understand mitochondria, which act like batteries in our cells to produce energy critical for normal function. Because the government's concession hinged on the presence of Hannah's underlying medical condition, mitochondrial dysfunction, some claim the decision is relevant to very few other children with autism. As a neurologist, scientist and father, I disagree.



Emerging evidence suggests that mitochondrial dysfunction may not be rare at all among children with autism. In the only population-based study of its kind, Portuguese researchers confirmed that at least 7.2 percent, and perhaps as many as 20 percent, of autistic children exhibit mitochondrial dysfunction. While we do not yet know a precise U.S. rate, 7.2 percent to 20 percent of children does not qualify as "rare." In fact, mitochondrial dysfunction may be the most common medical condition associated with autism .



Biological markers



Although unlikely, if the Portuguese studies are incorrect and mitochondrial dysfunction were found to be a rarity occurring in less than 1 percent of all autism, it would still impact up to 10,000 children (250,000 worldwide), based on current estimates that 1 million people in the U.S. (25 million worldwide) have autism. If, on the other hand, the research showing that 7.2 percent to 20 percent of children with autism have mitochondrial dysfunction is correct, then the implications are both staggering and urgent.



Autism researchers do not currently understand whether mitochondrial dysfunction causes autism or is simply a secondary biological marker. Autism clearly has many different causes, and should really be separated into multiple autism(s). I propose that we clearly identify and research the subpopulation term of "mitochondrial autism," which is distinguished by its unique biological, but not genetic, markers.



Based on what we know now, it is time to follow the prestigious Institute of Medicine 2004 report regarding autism and vaccines:



"Determining a specific cause (for autism) in the individual is impossible unless the etiology is known and there is a biological marker. Determining causality with population-based methods requires either a well-defined at-risk population or a large effect in the general population."



A paradigm shift



When the IOM report was published, mitochondrial dysfunction defining an autistic subpopulation was not firmly established. Today there is no doubt that mitochondrial dysfunction represents a distinct autism subpopulation biological marker. I urge health officials and the IOM to embrace their own report and pursue this breakthrough in the science of autism. National public health leaders, including those at CDC, must now recognize the paradigm shift caused by this biological marker with regard to their current position of dispelling a vaccine-autism link.



In light of the Hannah Poling concession, science must determine more precisely how large the mitochondrial autism subpopulation is: 1 percent, 7.2 percent, 20 percent?




Based on the 2004 IOM analysis, if the mitochondrial autism subpopulation is found to be relatively uncommon, then all conclusions from prior epidemiological studies refuting an autism-vaccination link must be discarded. New studies then need to be performed exclusively with the mitochondrial subpopulation. If mitochondrial autism turns out to be common, then we could re-analyze the data from prior studies to determine if these studies were powered sufficiently based on a predicted effect size. If not powered appropriately, the conclusion refuting an autism-vaccine link would again have to be rejected. These statistical concepts are basic.



The current vaccine schedule, co-sponsored by the CDC and the American Academy of Pediatrics, injures a small but significant minority of children, my daughter unfortunately being one of those victims. Every day, more parents and some pediatricians reject the current vaccine schedule. In an abundance of caution, meaningful reform must be performed urgently to prevent the re-emergence of serious diseases like polio or measles.



Need for research



As a neurologist, I have cared for those afflicted with SSPE (a rare but dreaded neurological complication of measles), paralytic polio and tetanus. If these serious vaccine-preventable diseases again become commonplace, the fault will rest solely on the shoulders of public health leaders and policymakers who have failed to heed the writing on the wall (scribbled by my 9-year old daughter).



The mitochondrial autism scenario that my daughter has so eloquently painted has the CDC and public health experts logically cornered. Denial and fear tactics won't close Pandora's Box. Whether we find that mitochondrial autism is rare or common, there is urgent research left to be done to fully understand the interrelationship of vaccines, autism and mitochondria.



Reform of the vaccine schedule will be an important part of the solution, whether vaccines play a major or minor role in autism. Our public health agencies and programs need a reconstruction plan. Day one of the reconstruction hopefully starts at the Vaccine Safety Advisory Committee's Working Group, to be held at HHS headquarters today in Washington.
