Mitochondria, autism and thimerosal

18 Apr

The whole mitochondria/autism thing is pretty fascinating. A Dr Shoffner presented the results of a study he conducted (‘Mitochondrial Dysfunction May Play a Role in Autism Spectrum Disorders Etiology‘ – its free registration at Medscape to read the whole thing) in which he noted:

a retrospective analysis of 41 children with ASD who were being evaluated for suspected mitochondrial disease showed that 32 (78%) had defects in skeletal muscle oxidative phosphorylation (OXPHOS) enzyme function and 29 of 39 (74%) harbored abnormalities in the OXPHOS proteins.

The numbers kind of leap out at you don’t they?

Except, we need to remember that this is a heavily skewed population. As SL has pointed out:

I can’t state it enough: this is NOT a random sample of autistic individuals. These are children who were already suspected of having a mitochondrial disorder.

Which is a bit like looking for wet kids at a swimming pool. It doesn’t really tell us anything about autism aetiology. It tells us that some kids who are autistic also have mitochondrial dysfunction. Reading anything concrete into that is just like reading anything concrete into the fact that autism symptoms become clear around the time vaccines are administered – correlation does not equal causation after all.

Dr Shoffner is unavailable right now but I have dropped an email off with him asking if he would be kind enough to make his presentation available. We’ll see.

In the meantime it should be noted that there are other highly respected mitochondrial researchers who are not pleased with the way that Dr’s Poling and Shoffner have conducted themselves. A researcher I am talking with commented:

….more harm than good has been done this time by Shoffner’s and Poling’s whipping up controversy but not providing the hard data that everyone needs….. Therefore, again, I ask that you serve the public good by not trying to ferret out partial data and incomplete statements from me or others, trust that nothing is being hidden by anyone, and wait for the full story to appear in a medical journal……offer assurance to your readers that the true story will be told and that misstatements of the legions of the uninformed and conspiracy mongers who are pursuing their own selfish aims will ultimately be revealed.

Strong words from someone who clearly feels that Shoffner and Poling are doing what they’re doing solely to be controversial.

So that seems to be the state of research regarding a mitochondrial aetiology for autism. Patchy and sensationalist with a clear agenda to serve personal interests.

However, as we all know, there are a group of people who want to take the autism/mito thing one step further and blame vaccines for triggering an occluded mitochondrial dysfunction which in turn causes autism. Its like a minor league domino effect with only three domino’s. Again, it reminds me very much of the early days of the thiomersal/MMR hypotheses – look for a direct cause and when one can’t be found, look for an indirect one and twist, twist, twist until you can argue for one.

Our old friend Ginger Taylor has, for example, been hopping from online newspaper to online newspaper saying in their comments section that:

The debate is over. Our highest health authorities have stated that vaccines are a cause of autism.

When in fact no such statement exists. Ginger is arguing that ‘features of autism’ is the same as a diagnosis of autism. Back in the real world of autism diagnostics, that is not the case.

So – what can we do to examine the hypothesis that thimerosal triggers mitochondrial dysfunction which in turn triggers autism? We could search for papers that mention thimerosal and mitochondria. When we do we get:

Of these, studies 4, 5 and 6 are not relevant – they’re talking about eyes. Its studies 1, 2 and 3 on this list that are articulatory relevant to us in our search for papers touching on vaccines>mito>autism. If anyone else finds any, please let me know in the comments section.

Now, these three studies are not supportive of the vaccines>mito connection. Why? They use frankly massive concentrations of thiomersal, way beyond whats contained in a vaccine. A quote from a scientist about these studies:

all of the studies used “non-physiological” concentrations of thimerosal – concentrations that would not be reached even by giving three or four (or even ten or twenty) high-thimerosal-containing vaccines to a low-weight and/or premature infant.

You can kill mitochondria with glutamate (an amino acid found in chicken soup, among other things), salt, oxygen, and a number of other things, if you use ENOUGH of it. The studies are not relevant…..because the concentrations used are so high – by a factor of at least 100.

So we seem to be back to square one. Whilst the evidence for a mitochondrial aetiology for autism is of mixed provenance and yet seems probable at some level, the evidence for thiomersal and autism-related mitochondrial dysfunction is not good.

Anti-vaccination and autism

16 Apr

I need to reproduce this comment from Amy Tuteur, MD on Autism News Beat. Its perfect.

“How does Dr. Tuteur explain parents who fully vaccinated and trusted the vaccination policy and then became disenchanted with it only after seeing their children seriously injured?”

Disenchantment is not the standard. The scientific evidence is the standard. It is not as though this hasn’t been studied. The purported link between vaccines and autism has been studied extensively and repeatedly. The scientific evidence indicates no difference in the incidence of autism between those who are vaccinated and those who are not. There is also no difference in the incidence of autism between those who received vaccines containing thimerosal and those who did not.

We’ve looked and the link simply isn’t there. That’s not surprising when you consider that the classic descriptions of the onset of autism, elucidated long before the use of multiple vaccines, is exactly the same as the onset of autism today. Vaccines do not increase the incidence of autism. Thimerosal does not increase the incidence of autism. The natural history of autism has not changed since the introduction of vaccines. It cannot be any clearer than that.

The conspiracy theories are a bunch of baloney. In order for there to be a conspiracy, someone must be hiding information. Doctors are vaccinating their children. Vaccine manufacturers are vaccinating their children. Immunologists are vaccinating their children. Who, precisely, is conspiring to keep information from the public and are we really supposed to believe that they would sacrifice their own children just to preserve the conspiracy?

Moreover, it isn’t as though doctors, immunologist and vaccine manufacturers are denying that vaccines have risks. It is well known that vaccines can and will cause small numbers of deaths and cases of brain damage. We have set up a compensation system precisely because we know about and acknowledge these risks. If doctors, immunologists and vaccine manufacturers are forthcoming about the risk of DEATH, isn’t it a bit absurd to suggest that they would hide the risk of autism?

One thing is certain, vaccine rejectionists do not understand immunology. Immunology is extremely complicated, so it’s not surprising that many people don’t understand it. However, the fact that they don’t understand it tells us nothing about immunology or vaccines, just like the fact that most people do not understand Einstein’s theories of general and special relativity tell us nothing about whether they are true.

Autism is a very serious problem. To the extent that we waste time, money, attention and effort on something that is not causing autism, we are diverting time, money, attention and effort from finding the real cause for autism. That is the saddest aspect of this incredibly sad situation.

I also recently read ‘Trusting blindly can be the biggest risk of all’: organised resistance to childhood vaccination in the UK which has some fascinating things to say on the anti-vaccine movement and their history. Consider this:

There is a small but fascinating social history literature which looks at the birth of resistance during this period in the form of groups like the Leicester Anti-Vaccination League and critical publications like the Vaccination Inquirer . Several of the accounts demonstrate the successes of organised campaigns which inspired marches of up to 100,000 people, riots, public burning of effigies of Edward Jenner, and the celebration of martyrs (Beck 1960, Porter and Porter 1988, Durbach 2000)…..Other accounts of this period stress the impressive ability of the anti-vaccinators to harness the power of the press (Howard 2003) and the important role of key individuals in pushing forward the movement.

Sounds familiar huh?

An Open Letter To The Poling’s

12 Apr

Dear Poling family,

Let me first start by saying that your little girl is beautiful. I am father to two girls (as well as one boy, young man now actually) so I know how great it is to have such wonderful little people around.

I read Jon Poling’s commentary in the AJC and I have to say that I was very disappointed by the level of accuracy in the piece. For example, he says:

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…

Now I have taken a keen interest in your families case since it became clear what the situation was. I _think_ I have read most of the newspaper reports available online as well as (more importantly) the HHS document itself and (even more importantly) the case study co-authored by Andrew Zimmerman and Jon Poling.

Nowhere, I repeat, nowhere, have I seen anyone from either the HHS, CDC, US Government, or even the Zimmerman/Poling case study say that ‘Hannah’s autism was triggered by nine childhood vaccinations’.

I have seen David Kirby refer to this several times. I have heard lots of people refer to these statements as if they are true and now I hear you doing it too.

But where is this concession?

In what legal, scientific or medical document does it state unequivocally that ‘Hannah’s autism was triggered by nine childhood vaccinations’?

You are a family on the cusp of storm. You need to take more care with your statements. People all over the world are listening. The *fact* as of right now is that no one has conceded ‘Hannah’s autism was triggered by nine childhood vaccinations’. Simply stating it as if it were true does not make it true.

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.

Now this confuses me on two levels. Firstly, Special Masters have already said that:

….in the case that is the subject of the media reports, if the parties who supplied documents and information in the case provide their written consent, we may then be able to appropriately disclose documents in the case.

It sounds to me like Dr Poling is trying to turn something around onto the HHS without justification. Maybe your legal team haven’t told you about this news. I understand they’re very busy of late.

The second part of Dr Poling’s statement that confuses me is the allusion to the records being released ‘to those representing the almost 5, 000 other autistic children’.

I thought that you wanted your documents to be made entirely public? Are you now saying you only want the legal teams of the other omnibus lawyers to have access to them?

I would also like to draw your attention to the email I sent to Terry Poling on March 5th asking why the Poling family had not cleared Dr Andrew Zimmerman from speaking publicly about the case. Does the Poling fmaily have any intention of lifting that embargo any time soon?

Dr Poling goes on:

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.

This is very disingenuous Dr Poling. I am not sure if you are purposefully distorting the truth or simply not as knowledgeable as you think. In point of fact the figure of 7.2% is from a 2005 study ‘Mitochondrial dysfunction in autism spectrum disorders: a population-based study‘. This is _not_ (as you state) ‘the only population-based study of its kind’. It was in fact a precursor to a _second_ follow up study by the same lead researcher correcting his own data.

This second study (published October 2007) is called ‘Epidemiology of autism spectrum disorder in Portugal: prevalence, clinical characterization, and medical conditions’.

This study declares a 4.1% figure. It is disingenuous in the extreme to refer to old science when newer, more accurate science exists on the subject (and by the same author no less!).

Further, as far as I can tell, the figure of 20% has but one source – a non published summary for attendees of a 2003 LADDERS conference in Boston, USA. Therefore it has not been subject to any kind of peer review. That’s not to say the figure is wrong, merely that it hasn’t been verified or undergone any kind of the usual scientific checks and balances a published piece of work must undertake to ensure quality. This is not ’emerging science’ Dr Poling. Its a set of program notes.

Further, as I understand it from talking to people involved in all three of these different items, the percentages you talk about are expressed percentages _of regressive autism only_ . Now I might have that wrong but I’m pretty sure that’s what was communicated to me.

Taking this into account, when Dr Poling states that:

In fact, mitochondrial dysfunction may be the most common medical condition associated with autism..

and he goes on to suggest population numbers between 10,000 (1%) , 72,000 (7.2%) and 200,000 (20%) of the autistic population he estimates at one million in the US, he is incorrect.

However, if I have understood what is said to me then we need to look at regressive autism numbers only, which are estimated to account for 25%-30% of autistic people. Therefore we are looking at not 7.2% or 20% (one is incorrect, one is not scientifically justified) of one million. We are actually looking at 4.1% (the only scientifically valid number) of between 25 – 30% of one million. Lets take the upper figure of 30%. This gives us a population of 300,000 for regressive autism. Applying the 4.1% estimate we can see that – at best and only if this data is all correct – mitochondrial autism may affect about 13,000 autistic people – 1.3%. If we took the lower range of 25% for regressive autism, we barely get over 1% (10,250).

Secondly, it should be noted that approximately 40% of autism can be accounted for genetically. This already makes it the single largest established cause(s).

Dr Poling goes on to say:

Today there is no doubt that mitochondrial dysfunction represents a distinct autism subpopulation biological marker.

This is true. However, prefacing this sentence with the word ‘today’ gives the highly misleading impression that autism has been associated with mitochondrial disorders and/or dysfunctions only since Hannah Poling came into out collective conciousness. This is far from the case. I can find instances in the scientific literature going back to 1986, over 20 years ago discussing mitochondria and autism and a PubMed search for ‘mitochondrial autism’ yields 34 quality papers published over a 20 year period. This is hardly a new thing Dr 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).

I fear that this is projection. You are very close to pushing an anti-vaccine agenda Dr Poling and indeed Terry Poling was active an the Yahoo Group ‘Recovered Kids’ from at least Summer 2001 where she says things like:

Really, the only way to obliterate a disease is to vaccinate everybody – or at least so “they” say

Sept 2001.

Had I told the hospital staff she was autistic they would not have believed me. The same held true for a (sic) educational consultant who came to evaluate hannah the day before the fever started. She said in her report she saw absolutely no autistic behaviors.

Nov 2001.

She has mitochondrial disease which causes her autism.

March 2004.

I do know docs that speak for drug companies but they cover all the meds for a particular disease in their talks with other docs. If they do not agree that the drug is best for certain conditions on the whole they say so.

Feb 2003.

…it [autism] is a DSM set of symptoms. When the symptoms disappear you cannot say the child still has autism…..

Oct 2001.

So Dr Poling when you try to lay the blame for vaccine preventable injuries increasing at the foot of those agencies assigned to try and stop them reappearing I think that is farcical. To me it is clear that the main responsibility lies with those who shun what are by and large safe safe vaccines on the strength of a hypothesis that is nowhere _close_ to scientific truth. I urge you to read this article and the comments left by readers. Its clear who they see as responsible. For example:

Don’t want to vaccinate your kids? Fine with me. Just don’t send them to school where they then put my kids at risk because of your decision.

You are deluding yourself if you think you can turn responsibility for shunning vaccines back on health agencies Dr Poling.

All in all Dr and nurse Poling I think that your public use of misinformation and erroneous science to make your point will serve you no good in the long run. I also continue to be puzzled by your refusal to ‘ungag’ Andrew Zimmerman. I hope you can start to realise that what has ‘happened’ to Hannah is far from remarkable. Best wishes from one autism parent to another.

Meet the new boss, same as the old boss

8 Apr

I got email from Ginger Taylor today. She’d read one of my posts on the ongoing Poling/HHS scenario.

I wanted to make sure you had see this from the VICP table.

It is part of the description of what vaccine induced encephalopathy is:

(1) A significant change in mental status that is not medication related; specifically a confusional state, or a delirium, or a psychosis;
(2) A significantly decreased level of consciousness, which is independent of a seizure and cannot be attributed to the effects of medication; and
(3) A seizure associated with loss of consciousness.

(D) A “significantly decreased level of consciousness” is indicated by the presence of at least one of the following clinical signs for at least 24 hours or greater (see paragraphs (2)(I)(A) and (2)(I)(B) of this section for applicable timeframes):

(1) Decreased or absent response to environment (responds, if at all, only to loud voice or painful stimuli);
(2) Decreased or absent eye contact (does not fix gaze upon family members or other individuals); or
(3) Inconsistent or absent responses to external stimuli (does not recognize familiar people or things).

As a matter of fact, I _had_ seen the table. Why Ginger wanted me to read it again I’m not sure. It doesn’t add anything new to the list of symptoms that both the HHS document and the Case Report document and thus we’re still no nearer a diagnosis of autism.

Anyway, after that she carried on:

That is an exact description of what most of us observed in our children when they regressed. When I went into my peds office with my son hanging limp in my arms and not responding to external stimuli, with absent eye contact, and dramatic change in mental status and a very marked decreased level of consciousness, and told him it all started after his vaccines, he should have diagnosed him with encephalopathy. A medical condition, that my medical doctor was charged with diagnosing.

But pediatricians are not taught to look for vaccine injury. Only autism. Because no one is responsible for autism. So instead he sent him to a speech therapist and a psychologist that diagnosed him under a DSM IV code of autism. He passed the buck because if he had done his diagnostic job correctly, he would have indited himself and the vaccine program.

And my doctor was a good doctor. He was not a shlub.

He would’ve indicted the vaccine program for what? Indicating a known vaccine injury was present? Huh?

This to me is the crux of the title of my post – meet the old boss, same as the old boss. People such as Ginger are not interested in _autism_ . They are not interested in being advocates for _autism_ . What they want is either a recognition that their docs screwed up and diagnosed their kids with the wrong thing (this is fine by me. The sooner these people are off the autism communities back the better) or for autism itself to be redefined to meet their own children’s symptoms. This is not fine with me.

This is nothing new. Way back in 2001, Bernard et al published Autism: A Novel Form of Mercury Poisoning which attempted the same ‘trick’ as is being attempted here – redefine autism to meet your own beliefs rather than see if what you believe fits the already established facts. As we have all been witness to, time has not been kind to the thiomersal hypotheses. Neither has it been kind to the MMR hypotheses.

Anyway, Ginger carried on:

Things are changing VERY quickly Kevin. The atmosphere here is much different than from what i understand is happening in the UK. Major networks are not ready to report on it yet, but they are listening to us now. Calling and asking questions even. Main stream docs were talking to me about integrating DAN methods into their practices before the AAP’s announcement last week. All of the sudden parents are getting their phone calls returned very quickly from sources that have blown them off for a long time. And I can’t keep up with my email.

I thought this would be a decade or more of fighting all this, but it looks to be more like the cascade of events when the Soviet Union fell. It is gaining speed. The Polings were the first major crack in the dam and now huge chunks are coming out faster and faster.

Kirby was right, the debate is over.

I had a quick grin at the sheer arrogance of comparing the autism/vaccine hypotheses to the collapse of communism in the old Soviet block but really, this again is nothing new. If I had a pound for every time someone had posted on here that ‘this is it, its all over’ I’d be richer by a fair few pounds. Of course, they always come to nothing.

The devil is in the details. And in the science. Mito connections to autism are nothing new. Attempts to ‘talk up’ and muddy the wide picture whilst failing to look at the details are nothing new. The media talking to people is hardly anything new (I had an interview myself recently and have had several in the past). Attempting to twist autism away from what is already known about it into something new to make it fit into yet another set of beliefs is not new.

I’ll say it again as I have before. Its a very exciting time for the media and bloggers as we have lots of cool stuff to talk about. However, none of that stuff is new science. And when it comes to vaccines causing autism that’s what is needed. Science.

The Next Big Autism Bomb?

28 Mar

Over on the Huffington Post, David Kirby has posted about The Next Big Autism Bomb. Its a very long post so take a sammich.

The gist (with apologies to Mr Kirby) of it is that there was a conference call to discuss the autism/mito issues:

On Tuesday, March 11, a conference call was held between vaccine safety officials at the US Centers for Disease Control and Prevention, several leading experts in vaccine safety research, and executives from America’s Health Insurance Plans, (the HMO trade association) to discuss childhood mitochondrial dysfunction and its potential link to autism and vaccines.

The purpose of the call was:

“We need to find out if there is credible evidence, theoretically, to support the idea that childhood mitochondrial dysfunction might regress into autism,” one of the callers reportedly told participants.

To that end, Mr Kirby mentions four studies throughout the rest of his piece. Three are accessible but the fourth is a total mystery. This is unfortunate as it is this fourth one which the majority of his blog post relies upon for its conclusions.

The first three are discussing what the prevalence of mito _within_ autism might be. Kirby states:

CDC officials were made aware of a Portuguese study, published last October, which reported that 7.2% of children with autism had confirmed mitochondrial disorders. The authors also noted that, “a diversity of associated medical conditions was documented in 20%, with an unexpectedly high rate of mitochondrial respiratory chain disorders.”

There is a slight point of confusion to clear up here. The figure of 7.2% is from a 2005 study ‘Mitochondrial dysfunction in autism spectrum disorders: a population-based study‘.

The study (by the same author) that Kirby mentions as being published last October is ‘Epidemiology of autism spectrum disorder in Portugal: prevalence, clinical
characterization, and medical conditions‘ declares a 4.1% figure.

The reason for this is that the lead author re-examined his data from the 2005 study and adjusted it downwards in the 2007 study. So Kirby is not correct to state that the authors believe that the rate is 7.2%. The latest figure from these authors is 4.1%.

The third study that discusses prevalence is referenced by Kirby as:

They also know that some reports estimate the rate of mitochondrial dysfunction in autism to be 20% or more. And the rate among children with the regressive sub-type of autism is likely higher still.

Kirby links to a web page that is the web interface to a mail list.

Upon searching for this paper I couldn’t find it anywhere. It is not in PubMed or Google Scholar and in fact I can only find three references to it online at all.

It since transpires that this paper is not in fact a paper at all and has not been published anywhere. It is in fact a summary for attendees of a 2003 LADDERS conference in Boston, USA. Therefore it has not been subject to any kind of peer review. That’s not to say the figure is wrong, merely that it hasn’t been verified or undergone any kind of the usual scientific checks and balances a published piece of work must undertake to ensure quality.

Its also been explained to me that the percentage of “mitochondrial autism” reported by any group will vary with the percentage of regressive autism in their ASD population. So it is not true that the summary states a differential between autism and regressive autism. Rather that “mitochondrial autism” exists _within_ regressive autism.

And so we move on to the fourth study.

One doctor reported his findings from a five-year study of children with autism, who also showed clinical markers for impaired cellular energy, due to mild dysfunction of their mitochondria.

The biochemistry of 30 children was studied intensively, and in each case, the results showed the same abnormalities as those found in Hannah Poling, participants said. Each child had moderate elevations or imbalances in the exact same amino acids and liver enzymes as Hannah Poling.

All thirty children also displayed normal, healthy development until about 18-24 months of age, when they quickly regressed into clinically diagnosed autism (and not merely “features of autism”), following some type of unusual trigger, or stress, placed on their immune system.

……….

But what causes the stress? That is a very big question.

Apparently, in only two of the 30 cases, or 6%, could the regression be traced directly and temporally to immunizations, and one of them was Hannah Poling. In the other cases, there was reportedly some type of documented, fever-inducing viral infection that occurred within seven days of the onset of brain injury symptoms.

Mr Kirby makes this study the raison d’etre of the rest of his post.

I have some major concerns about this. Who is this doctor? What is this study? Where is it published? Where can we _read for ourselves_ what this study says? Without wishing to question the honesty with which Mr Kirby is posting, its obvious that – even in this post as I discuss above – errors and misinterpretations have crept in.

Lets be honest here. These are some *major* claims being made. Firstly that all 30 kids in the study regressed into clinically diagnosed autism as opposed to features of autism. All 30? That’s incredible.

Secondly that 6% of the regressions into clinically diagnosed autism are traced directly from immunisations. That’s big. That is about as big as it gets. I would really like to see this study.

I have asked (twice) in the comments section of Mr Kirby’s post to be pointed to this study. So far, no answer has been forthcoming from anybody.

However. I note that Mr Kirby states that one of the 6% is Hannah Poling. If this is so then it is not true to say that:

the…[autistic]…regression…[can]… be traced directly and temporally to immunizations

(insertions mine for clarity).

As I’ve discussed before, none of the listed symptoms attributed to immunisations can accumulate to a diagnosis of autism. So unless we can actually see this study, know who the author, see what checks and balances this paper has undergone, we’re in a bit of a limbo.

Dear CDC

26 Mar

I read with interest Dr Schuchat’s opinion piece in the AJC today.

Whilst it is gratifying to see someone of Dr Schuchat’s calibre responding to previous claims regarding vaccines in autism I would like to make a few points to Dr Schuchat and the CDC in general.

Firstly, this level of response is around eight years too late. What have you been doing on the media/PR front over the last eight years? I’ll tell you what your ‘opponents’ have been doing – they’ve been conducting protests outside your offices, outside the offices of the AAP etc. They’ve been setting up and organising vaccine/autism groups and heavily marketing them via the use of organic and paid for web based advertising.

The only people who have made any kind of attempt to counter these groups and the misinformation (deliberate or not) they publish is people like myself. I am not attempting to aggrandise myself at all. I am attempting to convey to you how one sided the ‘battle’ has been over the last few years.

Where were you? You were needed. You could’ve helped. Instead you sat back and hoped this would all go away. It didn’t. It won’t.

Secondly, the level of Dr Schuchat’s response is very close to condescending. Simply stating that:

Kirby’s column included many inaccuracies related to childhood vaccines. As such, it illustrates that when it comes to immunizations, child development and specific medical conditions, the best source of guidance is the child’s health care provider.

is patronising in the extreme. The level and quality of the debate has moved on in the last eight years. Bland assurances won’t cut it. You need to be specific and offer evidence. Autistic people, parents of autistic people and interested professionals are smart enough to know and understand a certain level of science these days.

Don’t be shy about providing people with science. You have some truly excellent science on ‘your side’ as I and others have attempted to blog about in the last five years to no small effect. For example, Googling mmr autism displays, amongst others, the blog of a friend of mine – also the parent of an autistic child and also convinced of the need to blog about the bad science surrounding the various vaccine/autism hypotheses. Googling thiomersal autism brings up _this_ blog. We’re doing your job for you!

You’re being left behind in this debate. Its time you caught up.

Autism vs features of autism

14 Mar

In sum, DVIC has concluded that the facts of this case meet the statutory criteria for demonstrating that the vaccinations CHILD received on July 19, 2000, significantly aggravated an underlying mitochondrial disorder, which predisposed her to deficits in cellular energy metabolism, and manifested as a regressive encephalopathy with features of autism spectrum disorder.

– HHS

If one has the right set of “features” of autism, one has autism……Hannah Poling has autism — as defined in every book, in every library, in every university in the world. Dr. Parikh’s insistence otherwise is perplexing.

– David Kirby, to EoH group in response to Dr. Parikh’s article in Salon.

Its a massively ambiguous point. Do ‘features of autism’ equate to a _diagnosis_ of autism? David Kirby and some commenter’s to this site say ‘yes’. I personally think ‘no’.

But I think we need to be clear here. In this particular case, Hannah Poling can still be autistic but the HHS are arguing (in my opinion) that the features listed as those being aggravated/caused by vaccines do not add up to enough by themselves to give a diagnosis of autism.

To illustrate this idea, I went through the symptoms given by Dr Zimmerman that he put forward as being vaccine aggravated in a previous post (green = hit with DSM (IV), red = miss):

1) Loss of previously acquired language
2) Eye Contact
3) Relatedness
4) disruption in CHILD’s sleep patterns,
5) Persistent screaming
6) Arching
7) the development of pica to foreign objects,
8) loose stools
9) CHILD watched the fluorescent lights repeatedly during the examination

So, three of the symptoms given by Dr Zimmerman as being vaccine aggravated can be matched with the DSM (IV). This is way below what is needed for a diagnosis of autism.

But, we cannot discount the idea that she _could be_ autistic. To me, it seems likely that here is an autistic child who has her vaccines and who presents with nine symptoms following those vaccines, three of which tally with DSM (IV) criteria.

This presents two questions. First, is there a difference made by autism diagnosticians about autistic features vs a diagnosis of autism?

The best way to answer this is to ask autism diagnosticians. I wrote to some autism diagnosticians. They asked to remain anonymous, which I have to respect. The email I sent in essence asked them if they thought that:

a) ‘with features of autism spectrum disorder’ is directly equivalent to a diagnosis of autism?
b) ‘with features of autism spectrum disorder’ means that some elements of the DSM (IV) are present but not enough to diagnose autism?
c) ‘with features of autism spectrum disorder’ means that some elements of the DSM (IV) are present but not enough to diagnose ASD?
d) ‘with features of autism spectrum disorder’ means something else entirely?

The responses I got back stated that b) was most likely, maybe c) .

So according to these autism diagnosticians, some elements of the DSM (IV) are present but not enough to diagnose autism, or possibly ASD. This tallies with my own personal opinion.

The second question is; did Hannah Poling present with any diagnosable symptoms of autism _before_ her vaccines? Sadly, it seems we will never accurately know the answer to this question. The Poling’s will say no of course. David Kirby et al will say no of course.

I will remember the Cedillo’s however, who testified that their daughter (who they claimed was made autistic by vaccines) showed no symptoms of autism before her vaccines were administered. However, when home movies of their daughter taken before her vaccines were shown to several diagnosticians, they testified that she was indeed exhibiting symptoms of autism prior to vaccine administration. The Cedillo’s didn’t lie. Its simply not possible to remain clinically objective about one’s own child. Even for an employee of Johns Hopkins, it is not possible to remain objective about one’s own child.

That doesn’t mean Hannah Poling _did_ exhibit symptoms of autism prior to vaccines of course. It simply means that we need to be skeptical of the claim that she didn’t.

Is Hannah Poling autistic? Could be. Seems likely.

Did the vaccines cause the nine symptoms Dr Zimmerman found? HHS ‘concede’ they did.

Do the fact that three of those nine symptoms tally with the DSM (IV) mean that the vaccines are the cause of her autism? No, thats not logical.

Vaccines, Autism and the Concession

1 Mar

1) Concession Report (This document has been removed due to the possibility of it being illegally obtained). If people really wish to read the document for themselves it can be founf here, at the Huffington post
2) Zimmerman Case Study

When David Kirby wrote his piece in the Huffington Post, I’ll admit I read it with my jaw on my chest. Here was evidence I was wrong. I emailed David Kirby to get the whole report from him and he was kind enough to provide not only a PDF version but a plain text version as well.

This enabled me to contact a few people that I know are medical people and/or scientists and/or closely connected to this case. For example I contacted Dr Zimmerman and learned that it was not possible for him to offer any sort of opinion on this case due to the fact that his patients parents had not allowed him to discuss his thoughts and opinions with anyone except the court. I was told however that ‘the comments on your site with questions raised and loopholes pointed out about the way others are interpreting the facts of the situation, are right on track.’

It is clear to me then that there is some wordsmithing going on – either deliberately or unintentionally. What we need to do is look closely at the wording of two documents. The concession report and the case study performed by Dr Zimmerman.

The claim by David Kirby et al is, in essence, that the US Government have conceded that vaccines cause autism in this one case. Lets look at the so-called concession report in relation to what it says about autism.

Dr. Andrew Zimmerman, a pediatric neurologist, evaluated CHILD……on February 8, 2001. Dr. Zimmerman reported that after CHILD’s immunizations of July 19, 2000, an “encephalopathy progressed to persistent loss of previously acquired language, eye contact, and relatedness.” He noted a disruption in CHILD’s sleep patterns, persistent screaming and arching, the development of pica to foreign objects, and loose stools. Id. Dr. Zimmerman observed that CHILD watched the fluorescent lights repeatedly during the examination and would not make eye contact. He diagnosed CHILD with “regressive encephalopathy with features consistent with an autistic spectrum disorder, following normal development.”

Features consistent with. He did not diagnose her with autism. What were these features?

1) encephalopathy progressed to persistent loss of previously acquired language,
2) eye contact,
3) relatedness
4) disruption in CHILD’s sleep patterns,
5) persistent screaming
6) arching,
7) the development of pica to foreign objects,
8) loose stools
9) CHILD watched the fluorescent lights repeatedly during the examination
10) would not make eye contact

Of these ten, one is repeated (eye contact issues) so I make nine clear separate symptoms there. Which of these appear in the DSM (IV)? Green equal matches, red equal misses.

1) Loss of previously acquired language
2) Eye Contact
3) Relatedness
4) disruption in CHILD’s sleep patterns,
5) Persistent screaming
6) Arching
7) the development of pica to foreign objects,
8) loose stools
9) CHILD watched the fluorescent lights repeatedly during the examination

To meet the DSM(IV) criteria a person must meet no less than 6 of the criteria. So, as described perfectly exactly by the Dr Zimmerman in the concession report, this child has features consistent with an ASD. But its clear she does not meet the criteria for autism.

Later on,

CHILD was evaluated by Alice Kau and Kelley Duff, on May 16, 2001, at CARDS. The clinicians concluded that CHILD was developmentally delayed and demonstrated features of autistic disorder.

Almost the exact same phrasing. Consistent with. But no one has said thus far that the child has been diagnosed with an ASD.

The concession report concludes with:

the vaccinations CHILD received on July 19, 2000, significantly aggravated an underlying mitochondrial disorder, which predisposed her to deficits in cellular energy metabolism, and manifested as a regressive encephalopathy with features of autism spectrum disorder….

This is the phrasing that caused the uproar. But when looked at in light of the previous, it is clear that far from suggesting that vaccines cause autism via a mitochondrial disorder, the vaccines worsened an occluded or underlying mitochondrial disorder which took on a few of the symptoms of autism _but was never actually diagnosed as autism at all_ . Because it wasn’t autism.

Before we switch to Dr Zimmerman’s Case Study, lets clear up a few things.

No one, I repeat, no one is saying this child wasn’t autistic. She may well have been. What we are doing is looking at the science reported in the concession report and Zimmerman’s paper and seeing if what the _science_ says in these two papers means that it was the vaccines that caused any autism. The concession report clearly says that no it wasn’t. Thats why this case was uncontested. She was affected by her vaccines but autism was not the result.

Zimmerman’s case study is entitled ‘Developmental Regression and Mitochondrial Dysfunction in a Child With Autism’ – this is further evidence against the case presented that it was the vaccines that caused the autism. This child is reported as being one with autism. Not one who develops autism as a result of vaccines.

However, it is clear that this child _does_ develop autism:

We describe a female patient in whom developmental regression and autism followed normal development…..Evaluation at 23 months showed …..[t]he Childhood Autism Rating Scale (CARS) score was 33 (mild autism range), and she also met Diagnostic and Statistical Manual for
Mental Disorders-IV criteria for autism

and yet this autism was so mild that at that exact same period (23 months):

the patient began speaking again at 23 months old

which means that expressive language was lost for a sum total of one month (it is reported being lost at 22 months). It should also be noted that CARS is _not_ designed for diagnosis but is an indicator only. Overall, we get a picture of a child who had an underlying mitochondrial dysfunction exposed by the illnesses following her vaccinations which caused developmental regression. This developmental regression presented with some features of autism.

Did the vaccinations cause her developmental regression? Seems likely. It is an undisputed fact that vaccines do cause injury, that is why after all there is a compensation program to claim from in the US and the UK.

Was her developmental regression autism? No. At no point in either the concession report is it claimed that the developmental regression the child went through _was_ autism. However, in the same way that Leukemia (weakness, paleness; fever and flu-like symptoms) can have the same symptoms as flu (weakness, paleness; fever and flu-like symptoms) but be totally different, this child’s developmental regression shared certain features of autism.

So was this child autistic. She might well have been. However, her autism was not caused by a vaccine.

Update

This column was forwarded to me by a friend. Thanks to him.

The practice of calling certain things near-autism, or even autism itself is not new. Here’s a quote from a Science article regarding HIV in 1989:

The signs of AIDS dementia in children are clear and, Pizzo says, “very painful to watch. Very young children lose words.” Words like “mommy” and “daddy” and “bear” are too hard to remember as the AIDS virus multiplies in the young child’s body and penetrates the central nervous
system.

An 8-year-old boy, once normal, was rendered practically autistic by HIV, Pizzo said. He stopped speaking. Asked to trace a simple
outline of an elephant, the boy could not. Painfully, he knew what a simple task it was, and he knew he was failing it. But he could not cry even though his doctors could see tears welling up in his eyes.

Pizzo has seen children lose IQ points one boy lost as many as 28-as AIDS ravages their brains. “Kids who used to do well in school really deteriorate,” says Pizzo who has “before and after” IQ data from school-age children.

But in a series of remarkable studies, Pizzo has seen AZT (azidothymidine) reverse these symptoms. The child who lost words like “mommy” and “daddy” “got them back,” Pizzo says. The boy who lost IQ points is restored to his former capacity.

The 8 year old cries. After just a couple of weeks of continuous AZT therapy, the boy who could not trace an elephant is successful at tracing a horse.

Now, we all know that ‘tracing an elephant’ and losing IQ points are not symptoms of autism but it is intriguing to see a doctor describe a regression as ‘practically autistic’. Note also, just like in this case, in Zimmermans case study, the child quickly loses, then very quickly regains aspects of their former regression. But HIV didn’t cause autism any more than vaccines did.

US government concededs vaccine/autism case

26 Feb

As per this story from David Kirby in the HuffPo.

I have some doubts about it but lets see. I’ve emailed David Kirby to ask him to provide me with a full copy of the concession. His willingness to provide this information as well as the information itself should tell us more about what this concession report contains.

Ya ken that hidden horde, aye?

24 Feb

So – the ‘Hidden Horde’ – the term that anti-vaccinationists like to smirk about as evidence of an autism epidemic. The logic goes like this: if there’s no autism epidemic then where are all the [insert age here] year old autistic adults? I’ve heard people asking for evidence of 75 year old autistics (conveniently forgetting that the average mortality age in the US and UK is around 70), 50 year olds – even 30 year olds.

Never mind that there’s been plenty of evidence for adult autistics. Thats not convenient for the anti-vaccinationist agenda so it gets ignored.

Anyway, todays Sunday Herald carries another story about adult autistics in Scotland called ‘Revealed: ‘invisible’ adults living with autism’.

According to the National Autistic Society (NAS) Scotland report, due to be launched this week, 52% of adults have not had an assessment of their needs since the age of 18…..It is estimated that more than 35,000 adults in Scotland have the condition, but campaigners said they were “invisible” to local authorities, who are failing to record the number of people with autism in their area.

The population of Scotland is 5,062,011. The latest prevalence estimates for the UK are 1 in 100. This means that 50,620 people are autistic. If 35,000 adults in Scotland are autistic then 69% of autistic people in Scotland are adults.

Hidden horde aye?
