THE APPLIANCE OF SCIENCE

Kev has just blogged about a piece of research that examines the effects of Rhesus immune globulin (RhIg) on mothers of autistic children. RhIg is routinely given to pregnant women who are Rhesus negative to stop their immune systems from attacking their unborn babies. Because RhIg used to contain thimerosal, anti vaccine pressure groups who blame thimerosal for causing autism, have tried to implicate RhIg as well. A recent attempt to link an RhIg called Rhogam and Autism collapsed when the judge decided that the expert witnesses in the case were not up to the required standard. Kev blogged this as did Autism Diva, Orac, and Prometheus while Kathleen provided a HTML version of the decision on neurodiversity.com

According to a press release issued by the University of Missouri-Columbia

The results showed that in children with autism, Rh negative status was no higher in their mothers than in the general population, that exposure to RhIg (preserved with thimerosal) before birth was no higher and that pregnancies were not more likely to be Rh incompatible.

The press release quotes researcher, Judith Miles as saying,

We hope this report of no association between autism, Rh negativity and thimerosal exposure during pregnancy will offset some of the decreased compliance with immunization recommendations which is known to increase morbidity and mortality from childhood infectious diseases.

KNEE JERK REACTION AND FOOT IN MOUTH

This has produced a predictable response from Safe Minds spokesman, Mark Blaxhill, which Kev has demolished. But others are even more intemperate. Take Michael Wagnitz, for example. Writing online for the American Chronicle, in the space of 500 words he manages to imply that:

  • The researchers have been bought off by Johnson and Johnson to fabricate results that will aid them in vaccine damage litigation. Specifically he accuses them of suppressing data.
    • Originally, it was stated that the study contained 47 mothers with more than one child with autism. The published study lists only 16 such cases. Where did the other 31 cases go? Did they just disappear because they did not support her conclusion? Is this proper scientific ethics? This “data adjusting” is becoming quite common by mainstream autism researchers
  • They are deliberately sacrificing the interests of autistic children to promote their careers.
    • As a major player in the autism is a psychiatric condition caused by some unknown gene, the author knows that billions of dollars in research money is out there to be had. What will become of these “mercury apologists” if these kids ever receive proper treatment for what is causing their illness? Their multi-million dollars of funding will dry up. Their arrogant, controlling power trips will be over. They will become irrelevant.
  • A previous paper was “solicited” by Pediatrics and contained serious factual errors 
    • One paper cited, Nelson and Bauman 2003, was a paper solicited by Pediatrics to say that thimerosal does not cause autism. This paper was received and published on the same day. Did this paper even go through the peer review process? This paper is infamous for stating that ethyl mercury does not enter the brain.

Wagnitz is either ignorant or a liar. Here is a quote from the original paper.

 The passage of methyl mercury across the blood-brain barrier is facilitated by an active transport mechanism, whereas the passage of ethyl mercury into the brain does not have such a transport system and is further hindered by its larger molecular size and faster decomposition.32 At equivalent doses, higher levels of mercury have been found in the blood and less in brain following administration of ethyl mercury than methyl mercury.33 These findings support the observation that the risk of toxicity from ethyl mercury is overestimated by comparison with the risk of intoxication from methyl mercury.34 Ethyl mercury exposure has been reported to be more likely than methyl mercury to produce lesions of the spinal cord, skeletal muscle, and myocardium.8

In other words, Nelson and Bauman were arguing that exposure to ethyl mercury delivers less mercury to the brain than methyl mercury, not no mercury. Now, according to his byline on the American Chronicle, Michael Wagnitz has over 20 years experience evaluating materials for toxic metals. He currently works as a chemist in the toxicology section of a public health lab evaluating biological samples for lead and mercury. So I assume he knows how to read a journal article. Perhaps he was distracted by thoughts of his own vaccine damage case on behalf of his autistic child. This is a potential conflict of interest that he fails to mention in any of his articles about mercury and autism.

THE CURIOUS CASE OF …

Now, it is a curious fact that, while the mercury malicia automatically cast doubt on the credibility of any scientist whose work contradicts their case on the grounds that all scientists have sold their souls to big pharma and big government, if on the other hand a scientist can be persuaded to support their case, his or her scientific credentials are trumpeted to the heavens as incontrovertible proof of their reliability, impartiality and all round good guy credibility. Thuswise is Michael Wagnitz elevated to stardom by Ginger Taylor who gushes over the fact that Michael Wagnitz is an actual chemist who understands mercury.

AND FINALLY

Science operates via peer review. Someone or somebody’s research team suggests a hypothesis. Someone else comes up with an idea to test it. Somebody does the test and presents their work for publication. Fellow professional do the peer review. They look at the work and decide if it is worth publishing. It is. LUCKY YOU!

Peer review does not operate via bullying, lying, smear tactics or any other strawman or ad hominen attacks. This is in stark contrast to most of the outpourings of the litiginous mercury malicia. They are distorting science with their unreal and unscientific demand for certainty. They demand answers. Mostly all we have at present are questions.
