The Translational Genomics Research Institute (TGen), in collaboration with
the Southwest Autism Research and Resource Center, has launched one of the
largest and most comprehensive molecular and genetic studies ever conducted on
children with autism.
TGen's president, Dr Jeffrey Trent, served as the scientific director of the
National Human Genome Research Institute, which mapped the 3 billion-letter
blueprint of life. Approximately 50,000 genes reside within this blueprint, and
the complex interplay between all of those genes is what allows us to grow,
develop and function.
TGen and SARRC's collaborative approach to understanding and treating autism
is multi-faceted and takes advantage of the latest genome-scale technology.
While many human diseases are caused by a single defective gene, autism is a
complex genetic disorder, meaning that a series of genes, which are slightly
aberrant, come together and cause autism or a predisposition for an individual
to contract the disorder.
Our goal is to advance discoveries toward finding a cure for this insidious
neurobiological disorder and provide effective approaches to diagnoses and
therapies within the next five years," said Dr Trent.
"Our study is possible today only because of the mapping of the human genome,
which was achieved just two years ago this month. By identifying the biomarkers
associated with autism, we hope someday soon to provide for early diagnosis and
detection, and be able to suggest possible dietary and exposure modifications."
The study may ultimately involve samples and data from as many as 1,000
children with autism and 1,000 "typical" children who serve as control subjects.
TGen scientists and SARRC researchers will essentially be sifting through
almost every molecule of a group of children with autism and comparing findings
with data from children without the disorder.
"Technology exists today that allows us to obtain a simultaneous readout of
how all 50,000 genes are turned on and off within an autistic individual's
genome," said Dr Trent. "Additionally, all of the billions of data points that
are generated in our studies will be made publicly available on TGen's Web
servers so scientists worldwide can assist in interpreting the results. The
elegance of this approach is that we can use the expertise of the world's
collection of scientists to assist in curing autism and other disorders."
TGen's neurogenomics laboratory is the hub of a national consortium of genome
centres that provide state-of-the-art technology to roughly 3,000 investigators
who are all studying diseases of the brain.
"At TGen, our expertise and technology, combined with a passionate sense of
urgency for understanding disorders such as autism, have culminated in one of
the most powerful discovery engines in the world," said Dr Trent. "To provide
therapeutic options to children with autism and other disorders once we
understand the genetic underpinnings, we have solidified relationships with many
of the largest pharmaceutical companies to provide us with state-of-the-art
smart drugs, which will be effective against the disease process we identify.
"This initiative with SARRC represents a model for collaboration as TGen's
genomics expertise, latest genome-scale tools and sophisticated computer
hardware, bioinfomatics and resources complement SARRC's extensive knowledge of
autism and the organisation's many strengths in the areas of clinical research,
subject recruitment and enrollment and community-based support.
"Our hope is that the by-product of these two non-profit organisations will
soon: yield a highly regarded visible research study that is doing something
incredibly important for children and families; elevate Arizona's position as a
site for large-scale research studies and clinical trials; attract out-of-state
research funding from government grants, private industry and foundations and
discover the genetic underpinnings of autism, which ultimately will lead to a
cure."
Dr Trent added: "It is difficult to predict when we will have a cure for
autism, but the next five years will shed light on the underlying biological
processes that give rise to this tragic, complex disorder."
More than 10 families contact the Phoenix-based South-west Autism Research
and Resource Center every week after hearing their child's diagnosis of autism.
As well as the promising research under way in Arizona through SARRC's
collaboration with the Translational Genomics Research Institute, there is also
is an innovative community resource being developed in Phoenix that soon will
serve as a model for other research- and resource-based organisations across the
United States.
This model is called the Campus for Exceptional Children, and it is being
developed by SARRC together with families, generous community leaders,
compassionate businesses and countless other organisations committed to caring
for children.
The 18,000-square-foot facility will help SARRC to accelerate its research
into the causes of autism and the most promising intervention therapies;
effectively to respond to the needs of affected families; and facilitate
systemic changes in our community, from health care and service delivery systems
to classroom instruction, vocational skill development and long-term care.
Late last year, officials from the National Institutes of Health convened the
first-ever National Autism Summit in Washington, DC, to outline a long-term
inter-agency plan to deal with the increased diagnoses of autism.
SARRC's strategic plan falls into line with many of the challenging goals set
forth at the summit, including developing teaching methods which will enable the
majority of children with autism to speak; identifying genetic and non-genetic
causes of the disorder; and providing adequate services and resources to all
afflicted children and their families.

A syndrome of motoric and neuropsychiatric symptoms comprising various
elements, including chorea, hyperactivity, tics, emotional lability, and
obsessive-compulsive symptoms, can occur in association with group
-hemolytic streptococcal (GABHS) infection.
We tested the hypothesis that an immune response toGABHScan result in
behavioral abnormalities. Female SJL/J mice were immunized and boosted with a
GABHS homogenate in Freunds adjuvant, whereas controls received Freunds
adjuvant alone.
When sera from GABHSimmunized mice were tested for immunoreactivity to mouse
brain, a subset was found to be immunoreactive to several brain regions,
including deep cerebellar nuclei (DCN), globus pallidus, and thalamus. GABHS-immunized
mice having serum immunoreactivity toDCN also had increased IgG deposits in DCN
and exhibited increased rearing behavior in open-field and hole-board tests
compared with controls and with GABHS-immunized mice lacking serum anti-DCN
antibodies. Rearing and ambulatory behavior were correlated with IgG deposits in
the DCN and with serum immunoreactivity to GABHS proteins in Western blot.
In addition, serum from a GABHS mouse reacted with normal mouse cerebellum in
nondenaturing Western blots and immunoprecipitated C4 complement protein and -2-
macroglobulin.
These results are consistent with the hypothesis that immune response to
GABHS can result in motoric and behavioral disturbances and suggest that anti-GABHS
antibodies cross-reactive with brain components may play a role in their
pathophysiology.

Chromosome 2 Deletion Encompassing The MAP2 Gene In A Patient With Autism And
Rett-Like Features.
Pescucci C, Meloni I, Bruttini M, Ariani F, Longo I, Mari F, Canitano R,
Hayek G, Zappella M, Renieri A. Medical Genetics, Department of Molecular
Biology, University of Siena, Siena, Italy.
We present here a unique case of a 14-year-old female with autism and some
features similar to Rett syndrome (RTT). Genetic analysis demonstrated a large
deletion of chromosome 2q instead of a MECP2 mutation. Like a Rett patient, she
is dyspraxic and shows frequent hand-washing stereotypic activities, hyperpnea,
and bruxism. Like a preserved speech variant (PSV) of RTT, she is obese, able to
speak in second and third persons, frequently echolalic, and has final normal
head circumference and autistic behavior.
In addition, she has dysmorphic features such as down-slanting palpebral
fissures, low set ears without lobuli, bilateral flat feet, and bilateral
syndactyly of the second and third toes, which do not belong to the Rett
spectrum. She has a de novo chromosomal deletion in 2q34 of paternal origin.
Gene content analysis of the deleted region showed the presence of 47 genes
(14 putative and 33 known genes). This region contains some interesting genes
such as ADAM23/MDC3, CREB1, KLF7, and MAP2. Because alteration of neuronal
maturation, dendritic anomalies, and a decrease in MAP2 immunoreactivity in
white matter neurons are well documented in RTT patients, we propose MAP2 gene
as a good candidate for the generation of PSV phenotype in this case.

Social Withdrawal, Neophobia, And Stereotyped Behavior In Developing Rats
Exposed To Neonatal Asphyxia
Section of Behavioral Pathophysiology, Lab Fisiopatologia OS, Dipartimento
Biologia Cellulare e Neuroscienze, Istituto Superiore di Sanita', viale Regina
Elena 299, 00161, Roma, Italy.
Perinatal asphyxia is a concern for public health and may promote subtle
neuropsychiatric disorders. Anoxic insults to neonatal rats cause long-lasting
neurobehavioral deficits. In the present study, we focussed on changes in
emotional behaviors as a consequence of neonatal asphyxia in Wistar rats.
Newborn pups (24 h after birth) underwent a single 30-min exposure to a 100%
N(2) atmosphere (or air).
The offspring was tested for a) locomotor and exploratory activity with or
without a d-amphetamine challenge (0, 1, or 2 mg/kg) on postnatal day (pnd) 15;
b) social interactions and novelty seeking during adolescence;
c) levels of the brain-derived neurotrophic factor (BDNF).
In the open-field test (pnd 15), N(2)-exposed pups injected with the high (2
mg/kg) amphetamine dose exhibited reduced levels of locomotor hyperactivity, and
a more marked involvement in stereotyped behaviors. Individual differences
emerged in the locomotor response to the novelty-seeking test: two subgroups of
rats (separated on the basis of the median value) showed either
arousal/attraction or avoidance/inhibition in response to free-choice novelty.
The N(2)-exposed group showed a more marked novelty-induced avoidance and
inhibition. Time devoted to allogrooming and play-soliciting behaviors was
reduced, whereas object exploration was increased. Levels of BDNF were reduced
in the striatum of N(2)-exposed rats, suggesting poorer synaptic performance of
dopamine pathways.
In conclusion, these findings suggest an increased risk of developing social
withdrawal, neophobia and behavioral stereotypies (common symptoms found in
schizophrenia and autism) as a consequence of neonatal asphyxia in preterm
humans.

PUBLIC HEALTH
MMR Scientist Did Not Hide Link With Legal Case, Letter Reveals
Andrew Wakefield, the researcher who sparked the MMR scare with a paper in
The Lancet six years ago, did not cover up his links with the Legal Aid Board,
it emerged yesterday.
Dr Wakefield was accused at the weekend of failing to disclose the conflict
of interest over his research at the Royal Free Hospital in London, suggesting a
possible link between the MMR vaccination and bowel disease and autism, which
has led tens of thousands of parents to boycott the triple vaccination.
But he did reveal his links with the Legal Aid Board in a letter published in
The Lancet on 2 May 1998, less than three months after his original research
paper.
Responding to critics of his study who suggested it was suffering from
"litigation bias", he admitted that he had been asked to "evaluate a small
number of children by the Legal Aid Board". But he insisted that the children
had been referred to him through normal channels and there had been no bias in
the way they were selected.
The disclosure raises questions about why The Lancet did not repudiate the
study at the time on the grounds that Dr Wakefield's involvement with the Legal
Aid Board represented a conflict of interest. It only did so when the same
allegations were put to it last week by The Sunday Times, almost six years
later.
A four-month investigation by the newspaper revealed that Dr Wakefield had
received £55,000 from the Legal Aid Board while working on the Lancet study in
preparation for a possible claim against the vaccine manufacturers. At least
four of the 12 children in the Lancet study were also included in the study for
the Legal Aid Board. The money was paid into his research fund.
Richard Horton, editor of The Lancet, said at the weekend that Dr Wakefield's
failure to disclose the conflict of interest left his research paper "fatally
flawed". But the letter published in The Lancet in May 1998 made Dr Wakefield's
links with the Legal Aid Board clear. In the letter, responding to critics of
his paper published three months earlier, he wrote: "Only one author (AJW) has
agreed to help evaluate a small number of these children on behalf of the Legal
Aid Board." AJW are Dr Wakefield's initials.
The Lancet declined to comment on the letter yesterday but a spokesman for a
medical publisher suggested it did not amount to a full disclosure because it
came three months after publication of the paper, made an indirect reference to
the legal aid study and did not mention any payment.
Andrew Wakefield, the doctor who first raised fears of a link between autism
and the MMR vaccine, has hired a libel lawyer to demand an apology from The
Lancet after claiming that the medical journal has cast doubt on his honesty.
Dr Wakefield's decision to enlist the support of Carter-Ruck, the London law
firm that specialises in defamation suits, follows the denunciation of his work
last week by The Lancet.
Dr Richard Horton, the editor of The Lancet, who published Dr Wakefield's
findings in February 1998, said that he would not have printed the research if
he had known that Dr Wakefield was being paid £55,000 as part of a legal action
against the MMR vaccine's manufacturers. Dr Horton said that as a result of this
"conflict of interest", Dr Wakefield's research was "fatally flawed".
In a letter sent on Friday to Dr Horton, Dr Wakefield's lawyers have,
however, rejected the claims against him and demanded a full apology. It
said: "Our client entirely rejects your assertion that his work for the Legal
Aid Board gave rise to a conflict of interest in relation to the paper published
in The Lancet.
Four leading Midland doctors who deemed the controversial MMR vaccine safe
have links to the drug giants who make or supply the jab.
Campaigners have called for the General Medical Council to investigate the
senior Government advisors, who all hold scientific posts in the Midlands and
sat on key committees which declared the vaccine safe.
Professor James Chipman from Birmingham University, a member of the Committee
on Safety of Medicines, received research funding from GlaxoSmithKline,
suppliers of the MMR vaccine Priorix.
Consultant cardiologist Dr Colin Forfar from John Radcliffe Hospital in
Oxford, a shareholder in GlaxoSmithKline, is also a member of the influential
committee.
Professor Terence Stephenson, from the Queens Medical Centre in Nottingham,
sits on the same committee but his travel expenses are paid by the same drugs
giant.
Professor Michael Langman from Birmingham University is the Chairman of the
Joint Committee on Vaccination and Immunisation.
His team received research support from Merck Sharp and Dohme, which
manufactures MMR vaccine.
Now Jonathan Harris, West Midlands campaigner for vaccination awareness group
JABS (Justice Awareness and Basic Support) is calling for the GMC to investigate
the work of the medics.
Only two of Mr Harriss six children had the MMR vaccine and both of them are
autistic.
"A total of 19 Government experts are connected to the drugs industries that
deal with the MMR vaccines," he said. "Shouldnt this be considered a conflict
of interests? "These experts are advising the Government about the safety of the
MMR vaccine at the same time as receiving payments or holding shares in the
companies selling the jab.
"The Government requested that the GMC investigate the work of Dr Andrew
Wakefield, who first proposed the link between MMR and autism.
"They declared it was a matter of urgency when it emerged that he had
received funding from lawyers representing parents of children who felt they had
been damaged by the vaccine.
"So why shouldnt they investigate these doctors who have links to the drugs
industry while they are at it?"
The doctors watchdog GMC agreed to consider a full investigation into the
work of Dr Wakefield last week at the request of the Health Minister John Reid.
The medical researcher provoked a furore when he first proposed a link
between MMR and autism in a paper published in The Lancet magazine in 1998. In a
press conference later he also recommended parents opt for single jabs.
The editor of The Lancet has since said that he would not have printed the
study if he had known Dr Wakefield had received funding for it from the Legal
Aid Board. It emerged that Dr Wakefield received £55,000 from the Board to
investigate claims by parents that their children had been damaged by the
measles, mumps and rubella jab.
And the GMC has agreed to consider a full inquiry into the study following a
request from the Secretary of Health John Reid stating that it "was a matter of
urgency".
A spokesman for the GMC confirmed that the four Midland medics were
registered with them but declined to say whether it would consider opening an
investigation into their work and links with the drugs firms.
None of the doctors were available for comment last night. Their personal and
non-personal interests have all been openly declared to the independent advisory
committees on which they sit.
-- > ANOTHER THING YOU CAN DO ABOUT AUTISM NOW < --
Scores of parents whose children have autism gathered at the State Capitol
Thursday to send state officials a message about their loved ones
care: Treat now or else pay later.
The Families for Effective Autism Treatment rally was designed to raise
awareness that intensive in-home treatment isnt nearly what it was since the
state implemented changes as part of the 2003-05 state budget.
Bellevue mom Candee Eckberg said the changes mean about 10 fewer hours of
therapy a week and even fewer in about eight months for her son, Joshua, 4.
Eckberg said the one-on-one therapy has helped Joshua greatly over the past
two years, but she fears the changes will curb his progress.
"Hes come so far, but his help will be gone," said Eckberg, who had Joshuas
picture and placards that read "No child left behind" and "treat now or pay
later."
Eckberg joined the dozens of Wisconsin parents wearing yellow T-shirts and
toting their children or pictures of them as they gathered to hear speeches from
rally organizers and autism experts.
Their voices apparently have been heard: Gov. Jim Doyle said he would convene
a task force to seek solutions to the problem.
"The governor has been meeting with parents and providers, and he wants to
address the issues that have been brought to his attention and work with parents
and providers whove been active on this issue," Doyle spokesman Dan Leistikow
said. "He is in the process of forming a task force to address some of the
issues theyve raised."
Facing the loss of federal money as well as a $3.2 billion state deficit,
Doyle last year proposed ending the $30 million-a-year program, which covered
about 1,000 children a year with as much as 35 hours a week of in-home autism
therapy. He reconsidered following an outcry by parents that the program helped
their children.
The state restored some of the funding but had to make changes in order to
cover costs.
Many parents said that not only are their children now receiving less
therapy, but much of the reduced funding is tied up in administrative expenses
and not being used for direct services.
Ken and Janice Becker of Bellevue said their son, Justin, 13, went from 30 to
35 hours a week of therapy to seven. He actually only receives therapy about
four or five hours a week because of the administrative fees, they said.
The knives are out for Andrew Wakefield, the doctor who linked autism to the
MMR vaccine. Over the last few weeks, various reports have indicated serious
flaws in his research. News has also emerged that he received (but did not
disclose) £55,000 from a legal aid project set up to look for links between the
vaccine and the disorder. Richard Horton, editor of The Lancet, admitted that
his journal would not have published Wakefields paper in February 1998 had it
known about his conflict of interest. Stated simply, for the last six years
parents have been tortured by a myth.
With Wakefield discredited, the government now hopes that a line can be drawn
under this sorry episode. But I suspect that we have not seen its end. Wakefield
will emerge as a martyred hero, a brave and lonely warrior waging battle against
the conspiratorial medical profession. The pain he has inflicted on parents of
autistic children will continue.
In contrast to Wakefield, I intend to declare an interest at the outset. My
son Josh is autistic. Like most children, he was given the MMR vaccine at around
18 months. Shortly afterwards, he began exhibiting the first signs of what we
now identify as autistic behaviour. The link between these two events is
tempting, but, for reasons of sanity, I have resisted it.
In the vast majority of cases, autism manifests itself at around two years,
or, in other words, just after the MMR is administered. This coincidence
inspired Wakefields study. In 1998, his team reviewed reports of children with
bowel disease and autistic symptoms. Their research led them to conclude that
the MMR shot caused developmental regression, in some cases within 24 hours of
vaccination.
Needless to say, these findings sent shock waves through the medical
profession and, at a stroke, undermined the vaccination programme followed by
most countries. Worried parents withdrew their children from the MMR regime. In
this country, 91% of children received the vaccination before Wakefields
report. Coverage now stands at 79%, leading to fears that epidemics of measles,
mumps and rubella will result.
The flaws in Wakefields research are huge. His sample consisted of just 12
children, all of whom displayed autistic symptoms. In other words, there was no
control group of healthy children for comparison. The way the children were
selected also seems suspicious. In nine cases, the parents or paediatrician
speculated that the MMR vaccine had contributed to behavioural problems. So they
were already disposed to the idea of a connection. These children were referred
to Wakefield, rather than being a random sample of autistic children.
Furthermore, in four cases, the symptoms of autism pre-dated the administration
of the vaccine.
As far as Im concerned, these flaws are sufficient to reject Wakefield and
to conclude that I did not endanger my sons well-being by agreeing to the MMR.
Some parents, however, feel that the slightest indication of a link is
sufficient to decline the vaccination, even at the risk of exposure to measles,
mumps or rubella, which have potentially more catastrophic consequences than
autism.
To maintain suspicion requires not only ignoring the flaws in Wakefields
research, but also turning a blind eye to the large number of studies which show
no causal link. The conclusions of these studies are remarkably similar: all
show that, during the period under investigation, the incidence of autism has
increased dramatically, while the level of MMR vaccination has remained
virtually constant. If there were a link, one would expect the shape of the MMR
level of immunisation curve to be very similar to the autism case numbers, which
it is not. In the most comprehensive research, all children born in Denmark
between January 1991 and December 1998 were studied. Of 537,303 children,
440,655 received the MMR shot, while 96,648 did not. Researchers found no
difference in the incidence of autism between the two groups.
Some parents are nevertheless inclined to trust Wakefields skewed sample of
12 rather than the conclusions drawn from studying hundreds of thousands of
children around the world. The stubborn persistence of the MMR myth implies a
belief that the medical profession is riddled with corruption and that doctors
in many different countries have conspired in the forced administration of a
vaccine which is dangerous. Organising a conspiracy of such proportion seems
mind-boggling, especially since the precise purpose of doing so is unclear. As
far as I can tell, doctors have nothing to gain from administering the MMR,
other than the noble one of protecting the population from dreadful diseases.
The MMR myth is, I think, a symptom of our compensation culture. There was a
time when we accepted that some ailments had neither cause nor cure. We labelled
them acts of God. These mysterious diseases were part of life s lottery. But,
over the last century, the advancement of medicine has meant that many medical
conundrums have been solved. This advancement has, in one way, been to the
detriment of the medical profession. People nowadays believe that all ailments
should have explanation and cure. When they do not, the doctors are blamed, and
compensation is sought.
"Some autistic kids wander off or are drawn to water"
[By Michelle Ruby for the Espositor, Ontario. Available online for a fee at
below address. Thanks to Dennis Debbaudt.] http://www.infomart.ca
Many parents live with constant fear for the safety of their autistic
children.
Some youngsters with autism spectrum disorder seem to have a Houdini-like
ability to escape even the most secure rooms, homes, and yards. Caregivers need
only look away for a second for a child to slip out of view.
Sharon Allison was frantic when her four-year-old autistic son, Erik Vivian,
walked out the door of their Ontario Street home last summer. Erik, who speaks
very little, is unable to recite his name and address.
After a short search of the busy neighbourhood, Allison found her son, who
had been picked up by a concerned woman who called the police.
"He had almost been hit by a car."
Erik may have been the first autistic child the officer who responded to that
incident had met. But as the number of people being diagnosed with autism and
its related disorders increases, more contact with police is inevitable.
In fact, Dennis Debbaudt, who has made educating police officers about autism
his life's work, says people with the disorder and other developmental
disabilities are estimated to have up to seven times more contact with law
enforcement agencies during their lifetimes.
A private investigator based in Florida, Debbaudt has a 20-year-old son with
autism. Although his son is reasononably independent, Debbaudt worries that some
of his unusual mannerisms and speech patterns could be misinterpreted.
"Police could make errors in what they see and hear from him and think he's
high or drunk. Parents are afraid their autistic kids will scare others or say
or do something inappropriate."
Wandering, or elopement, is also common among those with autism spectrum
disorders. They may run on to busy streets or into a neighbour's home or
unlocked vehicle. Tragically, Debbaudt says, some of these so-called runners are
often attracted to water, and without real fear of danger, they will jump into
pools, ponds, and lakes without knowing how to swim.
Debbaudt said many police services are establishing registries for autistic
people, similar to those used to identify wandering Alzheimer's sufferers. Those
registries typically include the person's name, address, date of birth,
emergency contact information, medical concerns and a photo.
Insp. John Bates of the Brantford police said the department has been using
an Alzheimer's registry for many years to track wandering people who are
"usually located in a short period of time."
Bates said city police have not been contacted about developing a similar
registry for those with autism but said they are "always trying to further
integrate themselves with the community."
Clifford Gowan, president of the Brantford chapter of Autism Society Ontario,
also sees a registry as a possible life-saver for autistic people inside their
own homes.
"I'd like to have a registry with police and the fire department so those
people know what they're walking into in an emergency situation," said Gowan.
"There should be information in a database so that when a call came in they
would know that the second bedroom on the right belongs to the child with
autism."
Executive director Margaret Spoelstra said Autism Society Ontario has looked
at a variety of ways to identify autistic children who go missing. She said that
although several police services have expressed interest, some methods involve
confidentiality issues and can be costly to implement.
In the meantime, the autism society is doing what it can to help train police
officers to recognize the signs of autism and offer advice about how to approach
someone found wandering.
The group has purchased 300 copies of Debbaudt's autism awareness video for
law enforcement and distributed it across the province.
Police chiefs form all over Ontario attended a presentation made by Debbaudt
last summer and he plans to be in New Brunswick spreading his message later this
year.

AWARENESS
Parents: Autism Curable
"The San Mateo-Foster City School District is up to its neck in autistic
kids." -Dr. Jeff Bradstreet
These days, 8-year-old Sophie Horn is singing songs with a little more
melody. Its a nice change of tune for a child who was diagnosed with autism
when she was 2.
For decades, it was commonly thought that autism was an incurable state. Now
a growing legion of parents nationwide say their children are making complete
recoveries and San Mateo resident Elizabeth Horn Sophies mother is
documenting them in a new film.
Its a topic loaded with controversy, with no definitive findings about why
the number of autism cases has exploded in recent years. Between 1997 and 2002,
the number of autism cases jumped 87 percent around the state a trend thats
being echoed around the world. Doctors and special education officials cant
agree on the causes for the sudden spike, however, let alone whether its
possible to "cure" an autistic child.
In fact, some say these recovered children may never have been autistic in
the first place. Jim Cox, special education director in the San Mateo-Foster
City School District, said many of these children have other disorders that led
to "autistic-like conditions." Although children with autism can be taught, Cox
said it is essentially an "existential state" meaning thats just the way kids
are glued together from birth.
San Mateo [sic] doctor Jeff Bradstreet, who works closely with Horn, said
autism is curable, however. The condition is linked to the growing amount of
toxins children have been getting in recent years, he said, mainly through
vaccines.
Bradstreet maintains a Web site called the "Good News Doctors Foundation."
According to the Web site, the foundation is "a Christian ministry that provides
hope and information on how to eat better, feel better, and minister more
effectively as a result of a biblically-based, healthy lifestyle."
However, doctors at the Mind Institute, a leading research institution on
autism, say there is little to no evidence linking autism to vaccines.
A holistic cure
Autistic children get an onslaught of intervention in the San Mateo-Foster
City School District. Occupational, behavioral and speech and language therapy
are just some of the ways the district intervenes to help children become
functioning adults.
To truly recover, however, Horn said its critical to treat the child
holistically meaning parents should look at the biological and chemical
conditions that might be playing into the condition.
"Is there yeast in the gut? A gastrointestinal problem?" she said.
For example, theres a particular neural pathway that commonly shows
aberrations in autistic children. When that pathway is treated with Vitamin B12,
Horn said it can kick start a recovery. Since her daughter started getting the
treatment three weeks ago, Horn said shes seen significant improvements in
Sophies attention, language and behavior.
Other completely nonverbal children start talking in full sentences the day
after getting the treatment, she said. Thats just one of the treatments that
can lead to recovery.
"Every kid is different," she said. "Theres nothing definitive out there, so
parents have to be really motivated to find a cure they have to be self
starters."
Horn is encouraging doctors nationwide to create a database of children who
have recovered from autism. Once recovered, Horn said the parents often dont
want anyone to know their children were autistic.
"Theres this whole underground of parents out there who are just starting to
come out with their stories," Horn said.
Vaccines
Many parents swear their children were fine before receiving vaccines.
"Thousands of parents will show you videotapes of normal kids. Then they get
the MMR shot and theyre gone," Horn said. "When you have number of kids who get
very ill after getting a shot, its difficult to say the shot had nothing to do
with it."
Parents often assume vaccines are causing autism because the shots are
typically given when children first start showing signs of the condition, said
Cox.
"No, its not good to give mercury to kids, but that doesnt necessarily
suggest causation," he said. "Theres little accepted evidence to show it."
Cox said autism is a neurological condition that comes about when the neural
tube is being formed between the 17th and 25th days of gestation. Thats when
the fetus is most sensitive to alcohol, cocaine and other substances that cause
neural tube defects, he said.
Sally J. Rogers, a senior scientist at the Mind Institute, said there is no
evidence of a link between vaccines and autism.
"There have been a number of studies on the issue, but nothing showing
theres an empirical linkage. Theres just no evidence that vaccines have a
role," Rogers said.
That doesnt mean vaccines cant trigger an autistic condition for some
children, however, she said. Primarily, she said autism is the result of an
interplay of genes. Scientists are now researching how environmental conditions
could affect existing genetic conditions to spike the number of autism cases,
she said.
Although theres no definitive understanding about the explosion of autism
cases, some theories are more popular than others.
One of the leading and most controversial ideas is that a mercury
preservative in many vaccines, thimiserol, can have detrimental effects on
children who have genetic conditions that make them susceptible to mercury. The
U.S. government began phasing out the preservative a few years ago, but it
remains in some vaccines.
Its not a single shot that parents are blaming, however. When Horn was a
child, she said she only got about eight vaccines. These days, she said kids are
subjected to dozens.
"Over the past 20 years, the number of immunizations rose so dramatically,"
Horn said. "We never actually calculated how many micrograms of mercury kids are
taking."
Whether the increased number of vaccines are to blame, one thing is clear in
the foggy world of autism.
"The San Mateo-Foster City School District is up to its neck in autistic
kids," Bradstreet said.
It seems a scientist, such as Dr Andrew Wakefield (News and Leader, last
week), who uncovers genuine concerns about the safety of a vaccine has to be
'squeaky clean'.
In contrast, scientists who are vocal in support of the vaccine, and are
responsible for checking its safety, are allowed to receive research funding
from the company that produces it and to hold shares in the company, or act as
consultants.
These people will doubtless claim that they have declared a conflict of
interest. However, the declaration of a conflict of interest does not mean that
such a conflict does not exist. Which 'MMR scandal' is the Health Minister
proposing to set up an enquiry to investigate?

The furore over Dr Andrew Wakefield's 1998 Lancet paper is a storm in a
teacup. Your assertions that 'colossal damage has been done' are misleading
hyperbole. There is no evidence that the decision of many parents to shun the
MMR in favour of single vaccines is damaging.
Who has been damaged? Not the children. There were more than three times as
many notified cases of measles in the five years preceding Wakefield's paper
(1993-1997) as there were in the five years following it (1998-2002). More
people died from measles in the period 1993-7 than in the subsequent five years.
In fact no child under five (the age group the MMR is designed primarily to
protect) has died from measles since 1992. Experts have been predicting measles
epidemics for years.
'We could be on the verge of a public health disaster', proclaims your
editorial. Yet the real health disaster is the epidemic of autism. The numbers
of autistic children have risen 10-fold since the introduction of the MMR in
1988. Your leader is also incorrect to state that 'his fellow authors have
disowned the paper'.
The only way to discover the true impact of the MMR vaccine on the incidence
of autism in this country is to conduct a prospective study following children
up for many years. If that had been instigated by the Department of Health when
Dr Wakefield first shared his concerns in confidence with them in 1997 we would
by now have the answer.
