2Is there an Autism Epidemic?
- Before 1985, the total incidence of Autism was
3-5 per 10,000 Births (12000-3000). Most cases
were from acute medical problems, present since
birth, and caused by known genetic disorders - By 1997, the rate of autism had increased to 30
per 10000 births (1333), with 80 regressive
type, after a period of normal development - In 2004, the AAP reported the incidence of ASD at
1166 - In 2007, the CDC has revised the incidence to
1150 - Many people refuse to call this an epidemic,
saying that this is just due to better diagnosis
and awareness - The DSM-IV criteria for Autism has NOT changed
since the early 1990s
3Autistic Spectrum Disorders
- ADHD Aspergers PDD Autism
- Syndrome
- In many of our patients, there are multiple
biological abnormalities
4Discover Magazine, 3/14/07
5Intestinal
- Abnormal flora (dysbiosis)
- Abnormal permeability (leaky gut)
- Illeal lymphoid hyperplasia
- Persistent Measles virus
6Immune System
- Th1 Th2 type of WBC
- Low TH1 can cause susceptibility to infections,
with potential increased exposure to antibiotics. - Related Yeast Overgrowth in Intestinal Tract as
well as Clostridia and Parasites - High TH2 can lead to inappropriate antibody
formation - Auto-antibodies
- Food antibodies
7Biochemical Abnormalities
- Low sulfur amino acids
- Low zinc levels
- Low selenium levels
- High copper to zinc ratios
- Low omega 3 fatty acids
- High ammonia levels
- Abnormal methylation metabolism
- High microbial metabolites
- Elemental Toxins Mercury, Lead, etc
8Robert Cade, MD, Professor, University of
Florida Medical School
- A gluten and casein free diet resulted in
significant improvement in 81 of children with
autism within three months.
9Rationale for Casein/Gluten Free Diet
- Gluten and casein have immune, as well as
neurotransmitter impacts. - Many ASD children have food hypersensitivities
- Improper digestion leads to buildup of
opiate-like peptides. These can be identified in
the urine of many children with ASD. - Dr Cade at UF recently injected rats with
casomorphin, causing the rats to develop
autistic-like behaviors
10DPP-IV
Dipeptidyl Peptidase IV, carboxypeptidase A, and
aminopeptidase are some of the main enzymes that
brake down the opiate peptides. Some of the
enzymes are zinc dependent, and its activity
can be inhibited by mercury, among other
things. A first generation enzyme containing
DPP-IV is available from Kirkman Labs. Although
for most children it can not serve as a sole
replacement for the C/G free diet, giving it with
these foods allow some children to take c/g foods
with out negative reactions, and it can be
administered in cases of accidental exposure
11Dr. Lewis book is the essential starting point
for a gluten and casein free diet.

to Children with Autism
February 28, 2007
16Abnormal Stool Urine Findings
- Best, and in some cases imperative to treat these
prior to starting more advanced therapies such as
chelation - Stool Yeast (Candida), Parasites (Giardia,
Dientameoba, and others), Malabsorption, Blood,
etc. - Urine Yeast and Bacterial metabolites, abnormal
Krebs cycle metabolites, oxalates, opiate
peptides, etc
17Treat Stool Urine Findings
- Yeast Killers Nystatin, Diflucan, Sporonox, Uva
Ursi, MCT, goldenseal, Garlic, Candex (digestive
enzyme) and others. - Clostridia Killers high dose lactobacillus,
Metronidazole (benzoate by compounding),
Vancomycin - Parasites the ones we see most often are also
sensitive to Metronidazole Benzoate, other
specific natural and pharmacological agents used
depending on the particular organism
18OAT test
19OAT After Culturelle and Nystatin
20Nicholas (8 y/o)After Culturelle and Nystatin(3
months later)
- Attention span has definitely improved since the
last visit. - getting very good reports fro the teachers
- more "with it", not spacey
- now will respond much faster when spoken to.
- Reading skills vastly improved, with good
comprehension skills. Reading instruction manuals
and understanding it. Wants to keep reading on
and on. - performing skills at school that he never did
before. Amazing memory for spelling. - Learned how to tell time.
- Can perform addition.
- less problems with interactions with his peers,
but he prefers solitary play when in his house.
When visiting others he will interact more. He
does much better in small and quiet groups - getting better balance of his body.
21Sulfation
- Sulfur is an element critical to the structure
and functioning of body mechanisms. - Dr. Rosemary Waring reports that most autistic
children show a deficiency of sulfates in their
plasma. Of the autistic children she tested, 92
had sulfate levels that were only 12 of normal - Low sulfates can lead to a leaky gut, as well as
a weakness in the phenolsulfotransferase (PST)
system. - the PST pathway is important in removing toxins
- A weakness in the PST system is often
characterized by night sweats, red face and ears,
allergies, and keratosis pilaris (red bumps on
back of arms) - Tx Epsom Salt by bath or transdermal
application, or oral sulfates such as glucosamine
sulfate and MSM
22 23After Epsom Salt Baths
24Erics (6 y/o) Response to Epson Salt Baths
- Making new statements. Becoming more creative
with language. Responding to answers
appropriately - still needs help focusing for long periods of
time, but paying more attention - echolalia is gone
- showed much more interest in presents that he
received for the holidays. - getting more involved with his brother, they are
fighting a bit now.
25Ammonia
- Ammonia is a known toxin to the brain.
- High enough levels can cause can cause
neurological symptoms, even coma. This is usually
associated with liver disease - About 5-10 of ASD patients we check have mild to
moderate elevations in Ammonia levels (in the
presence of normal liver tests) - Proposed mechanism Proteins gtgt Amino Acids
gtgtAmmonia gtgtliver fuses 2 ammonia molecules to
form urea gtgt excreted in urine. Gut pathogens
gtgt leaky gut. Urease enzyme made by certain gut
pathogens gtgt Urease enters the bloodstream gtgt
splits urea back to ammonia at a pace faster then
urea can be formed.
26Connors original Ammonia level
27Connors ammonia after 2 capsules of alpha
ketoglutaric acid
- Increased speech, repeating everything
- socializing better, especially with sister
- Separation still a problem when school starts
- When peer tantrums, Conor gets upset. He did
approach a crying child instead of running away,
and when sister was crying he sought help instead
of withdrawing
28Connor After 4 capsules of Alpha Ketoglutaric
Acid
- No more episodes of the rapid eye blinking or
enlarged pupils - interacting better with sister
- less melt-downs when others tantrum
- speech improving on a weekly basis
- sound sensitivities seem to no longer be a problem

35Immunity is complex and impacts every system in
the body. It isnt surprising that it effects
child behavior and development.
36Immune System
- TH1 TH2 type of WBC
- Viral Stimulation
- Inappropriate antibody formation
- Auto-antibodies
- Food antibodies
- Frequent Infections - Especially Ear
- Related Yeast Overgrowth in Intestinal Tract w/
Clostridia and Parasites
37PPARS (Peroxisome Proliferator-Activated
Receptors)
- Used in DM type II to increase insulin
responsiveness - 2 effect decreases Th0 moving towards Th1 and
away from Th2. - Boris et al at NYU studied 350 ASD children
using ACTOS, showing significant increases in
cognition, calmness, verbal skills and
socialization, with decreases in aggression and
diarrhea. 22 of these kids had hyperactivity, 9
had periorbital edema, 34 had weight gain, 0 had
hyperglycemia or hyperinsulinism - Cytokines pre and post treatment have been
measured, improvements in MBP autoantibodies and
thyroid autoantibodies have been documented.
38IMMUNIZATIONS
- I am not suggesting that we abandon our
vaccination policy - I am concerned about the growing number of
chronically ill children - There are more children with learning
disabilities and autoimmune disorders then there
has ever been in the history of medicine.
39Concerns about Vaccines
- Are we unnaturally stressing underdeveloped
immune systems beyond their capabilities in our
effort to keep the children from becoming ill? - There are inadequate safety studies for the
vaccines that are currently on the market - Are we giving too many vaccines over a short time
span? - We do not have a clear understanding of the
effects of some of the vaccine components such as
thimerosal, aluminum, formaldehyde, and human
fetal tissue.
40Whats Going On?
- Social deficits, shyness, social withdrawal
- Repetitive, perseverative, stereotypic behaviors
obsessive-compulsive tendencies - Irritability, aggression, temper tantrums
- Lacks eye contact impaired visual fixation
- Loss of speech, delayed language, failure to
develop speech - Speech comprehension deficits
- Sound sensitivity mild to profound hearing loss
- Abnormal touch sensations touch aversion
- Flapping, myoclonal jerks, choreiform movements,
circling, rocking, toe walking, unusual postures - Poor concentration, attention, response
inhibition - Self injurious behavior, e.g. head banging
- ADHD traits
- Sleep difficulties
- Diarrhea abdominal pain/discomfort, constipation
- ALL SIGNS AND SYMPTOMS OF
- MERCURY TOXICITY
41MERCURY
StatementPediatrics 2001 Jul, American Academy
of Pediatrics Committee on Environmental Health.
The developing fetus and young children are
thought to be disproportionately affected by
mercury exposure, because many aspects of
development, particularly brain maturation, can
be disturbed by the presence of mercury.
Minimizing mercury exposure is, therefore,
essential to optimal child health..Mercury in
all of its forms is toxic to the fetus and
children, and efforts should be made to reduce
exposure to the extent possible to pregnant women
and children as well as the general
population. ______________________________________
_________________________ Vaccine inserts would
typically say 0.01 thimerosal as a
preservative, which to anyone would sound like
an extremely small amount. When called to testify
in front of the Institute of Medicine, an
independent group formed by our government to
monitor safety issues, Dr. Neil Halsey of Johns
Hopkins University, and head of the vaccine
recommendation committee that reports to the CDC,
went on record as saying No one ever did the
math. No one knows what dose of mercury, if any,
from vaccines is safe. We can say there is no
evidence of harm but the truth is no one has
looked
42Mercury/Thimerosal
- Thimerosal is Ethylmercury, a neurotoxin
- Mercury was found in the blood of newborns even
before Hepatitis B shot, and higher levels after
the shot. - Journal of Pediatrics, May 2000
- In some pre-term infants, mercury levels were 10
times that of term infants - Pre-term babies are vaccinated according to
chronological age, not gestational age.
43Mercury/Thimerosal
- Intrauterine sources may include
- maternal fish consumption
- mercury amalgam fillings
- Rhogam (given to Rh (-) mothers, no longer
present) - Influenza vaccine (still present)
44Mercury/Thimerosal
- Hepatitis B vaccine was introduced in 1991- with
most newborns getting the first dose before
leaving the hospital - Hep B vaccine had contained 12.5 mcg of
thimerosal 6.25mcg mercury - EPA established the safe limit at 0.1
mcg/kg/day, approximately 0.4 mcg/day for an 8
pound newborn
45Mercury/Thimerosal
- Typical Thimerosal Exposure for 2 month old
infant - Hep B 12.5 mcg
- DTaP 25 mcg
- Hib 25 mcg
- Total 62.5 mcg
- of which 50 is ethylmercury 31.25mcg
- Total safe dose for 10 pound (2 month old) baby
by EPA standards 0.5 mcg. The average 2 month
old received 60x the EPA limit
46Mercury/Thimerosal
- By 6 months of age, a fully vaccinated infant
would have received - 3 DTP 75 mcg thimerosal
- 3 Hib 75 mcg thimerosal
- 3 Hep B 37.5 mcg thimerosal
- Total 187.5 mcg thimerosal
- 93.75 mcg mercury
-
- 1999 FDA Center for Biologics Evaluation and
Research
47Mercury/Thimerosal
- Thimerosal was used as a preservative in all
multiple dose vaccines (10 doses/vial) - Shaken vs. Stirred
- The 10th child may receive 125-250 mcg per dose
if the mercury has settled - In 1999, the CDC called for Thimerosal to be
removed from all vaccines. - Physicians were told it is OK to use up the
vaccines that they already have
48Heavy Metal Exposures
- After exposure to mercury, the length of time to
be eliminated varies for different organs - Blood and Hair 4-6 months
- Non CNS organs several years
- Brain 20 years
- (Boyd Haley, PhD, University of Kentucky, Dept of
Chemistry) - Lead typically deposits into brain and bone.
After exposure to lead, within several months the
blood and urine levels will be normal even if the
lead is still in the bone and brain (Clarkson,
2002)
49Whos looking into all of this?!?!?!
Mark R. Geier, MD, Ph.D. (Submitted to the
Institute of Medicine, of the US National Academy
of Sciences, January 2004
- There was a 6-fold statistically significantly (p
lt 0.05) increased incidence rate of autism
reported to VAERS following thimerosal-
containing DTaP vaccines in comparison to
thimerosal-free DTaP vaccines. (analyzing data
comparing thimerosal vs. thim-free DTaP) - In analyzing the Vaccine Safety Datalink In the
group receiving a minimum of three doses of
thimerosal-containing DTaP vaccine only in
comparison to our group receiving a minimum of
three doses of thimerosal-free DTaP vaccine only,
that there was statistically significantly
increased risk for autism (relative risk 27.6,
attributable risk 3.81 per 10,000 children, p lt
0.0001). - What does the AAP conclude about Geiers
research? - Study Fails to Show a Connection Between
Thimerosal and Autism from the AAP webpage,
Posted May 16, 2003
50Whos looking into all of this?
- Boyd Haley, PhD, Department of Chemistry
Chairman, University of Kentucky. Dr Haley is
considered one of the leading researchers in
America on Heavy Metal toxicity - He reports that exposing neurons to thimerosal
rapidly results in the stripping of tubuluin
from the nerve axon, and also reduces the
viability of actin. Actin and tubulin are
proteins that are critically important for the
growth of dendrites and to maintain the structure
of the axon. - On exposing neurons grown in culture for 24
hours, then exposed to vaccines with thimerosal
and thimerosal-free vaccines. There was
significantly more cell death in those exposed to
thimerosal vaccines. The most concerning part
about this was that there was an extremely low
amount of thimerosal used in the study, 10K less
then the concentration found in most vaccines
51Whos looking into all of this?!?!?!
- When cultures of the same were then co-exposed to
thimerosal and aluminum, and those cells died
much faster then those with thimerosal alone - The same neurons were then taken and half
received thimerosal and estrogen, and half
received thimerosal and testosterone. Those with
estrogen co-administered were protected against
thimerosal-induced neuron death. Those
co-administered with testosterone had a very
large increase in neuron death. This may explain
the 51 ratio of boysgirls. - His conclusion, as presented to the Institute of
Medicine Immunization Safety Review committee
To date the data has been very consistent the
toxicity of the vaccines is primarily dependent
on the presence of thimerosal, and in my opinion,
thimerosal containing vaccines would be
classified as severely toxic to numerous brain
proteins
52Whos looking into this (cont)
- The following are excerpts from posters presented
at the November 2002 International Meeting for
Autism Research - Hornig et al, Center for Immunopathogenesis and
Infectious Diseases, Mailman School of Public
Health, Columbia University, demonstrated that
early postnatal administration of thimerosal
using doses and timing that mimic the childhood
immunization schedule induces mouse
strain-specific effects on weight gain, locomotor
and exploratory activity, stereotypic behaviors,
and size of certain regions of hippocampus. SJL/J
mice, a strain with heightened sensitivity to
autoimmune disease, show the most prominent
behavioral and neuropathological effects. In this
strain, male gender is associated with a more
severe outcome. (This associates a potential
genetic predisposition may give way to a subset
of subjects that are biologically susceptible to
toxic effects on the brain.)
53Whos looking into this (cont)
- Holloway et al, Arizona StateOral antibiotics
have been shown in rats to increase the half-life
for excretion of mercury from 10 days to over 100
days. (Doctors have been told it is OK to
vaccinate children as long as they are not
seriously sick, with high fevers, and there is no
recommendations not to vaccinate children on
antibiotics) - Holloway et all, Arizona State 2002 carried out a
DMSA challenge study involving 15 children with
autism and 15 typical children. The children
received a single dose of meso-2,3-dimercaptosucci
nic acid (DMSA), at a dose of 10 mg/kg, followed
by a 10-hour urine collection. The DMSA resulted
in a much greater increase in heavy metal
excretion in the children with autism compared to
the controls. Many of the children with autism
excreted high levels of one or more heavy metals,
although there was wide variation in the amount
and type of metal excreted. (The data suggests
that many children with autism have a greatly
diminished ability to excrete heavy metals, and
thus would be unusually vulnerable to exposures
to those metals)
54Mercury Testing
- As there is a relative short half life of mercury
in serum, blood and urine testing will often be
negative if more then 6 months have passed
between exposure and testing - Hair tests can be falsely positive if there are
metals in shampoos, conditioners, or water. Also,
there is evidence that mercury levels in the hair
of autistic children is less than in controls
(Cave and Holmes) - For me, the best test is an oral chelation
challenge, extracting the heavy metal and
excreting it in the urine. This can document that
the metal is present, it is not being excreted
under normal circumstances, AND that the
chelation agent and the route of administration
given works for the individual
55Mercury Removal Chelation
- Agents
- EDTA, Dimercaprol (BAL), DMSA, DMPS, and DMPA
all have heavy metal binding activity - Marked specificity for heavy metals, but also can
cause decreases in trace elements and
micronutrients (and these should be tested for
periodically) - Mercury is essentially irreversibly bound to
DMSA, so mercury is not deposited in other
tissues, even the kidney. - DMSA/DMPS works through increasing urinary
excretion. - DMSA/DMPS does not cross the blood-brain barrier,
so no risk of delivering bound mercury to the
brain - Very low toxicity. Side effects may include
anorexia, nausea, vomiting, diarrhea, rash and a
transient increase in liver enzymes. - There are no known adverse drug interactions with
DMSA/DMPS. - EDTA disodium vs Calcium disodium. Disodium EDTA
given rapidly by IV can suddenly drop serum
calcium levels. Only should use CaNa2 EDTA
56Mercury Removal Chelation
- oral (DMPS and DMSA)
- IV (DMPS and CaNa2 EDTA)
- Rectal (DMPS, DMSA, CaNa2 EDTA detoxamin).
- best to have stool passage before insertion
- CaNa2 EDTA seems to cause less yeast exacerbation
- TD emu oil seems the best vehicle
- seen very little benefit/movement with DMPS
- seen some positive excretions with DMSA
- CaNa2 very difficult to keep in suspension
without precipitation
57Single dose chelation challenge
- baseline urine taken before dose given
- 8 hour urine collection regardless of type/route
- empty bladder before giving dose
- DMSA (oral or rectal 25mg/kg)
- DMPS (3mg/kg for IV, 10mg/kg for rectal,
5-10mg/kg oral) - CaNA2 EDTA (25-50mg/kg regardless of rout,
maximum of 1500mg) - May need to do more than 1 challenge with
different agents/routes - (DAN! 2005 Consensus Paper)
58Antonio (7 y/o) on first chelation challenge with
DMSA

60Antonio, after 8 cycles of DMSA
61Antonio After Chelation with DMSA Has bad gas
during the DMSA days, and is moody, then this
goes away when the DMSA is finished. Doing
better and better in speech therapy If he does
not want to do things he cries. Teachers are
reporting improvements seen on a month-to-month
basis More hand gesturing In a more advanced
class. The mimicry behavior has stopped. At this
point language is the major barrier, behaviors
and stemming are under control

68Urine Porphyrins
- Porphyrins represent a group of uniquely
structured compounds that can surround different
types of ions/metals. Each has a specific
biological function - Hemoglobin
- Myoglobin
- Chlorophyll

Enzymes the keys to life A B 0
C 0 D A B are substrates, the
ingredients being mixed together 0 is the
enzyme, the catalyst that makes the reaction
proceed. C D are products made by the
reaction, which can then go on to be substrates
(ingredients) in other reactions Some enzyme
reactions can go both directions
70Biochemistry 101
A B 0 C 0 D
What can cause an enzyme not to work?
- Not enough or particular substrate
- The genes that code for the enzyme are abnormal,
creating a damaged or inefficient enzyme - Something poisons the enzyme so it wont work
- Too much of a product (D) drives the reaction in
the other direction
71Urine Porphyrins
- Certain toxins, such as heavy metals and
pesticides can inhibit certain enzymes in the
heme porphyrin pathway, leading to specific
porphyrin profiles being excreted into the urine.
If an enzyme is inhibited, the substrate
upstream can build up. - Aluminum and dioxin inhibit uropophyrin
decaboxylase. - Mercury inhibits coproporphyrinogen oxidase.
- Lead inhibits coproporphyrinogen oxidase and
aminolevulinic acid dehydratase. - (Woods, 1996)
- Second urine void of the day is the best
collection, as supplements that cause oxidation
if mixed with the porphyrins overnight in the
bladder can change the structure of the porphyrin
lead to false values (Martin, 1996)
72Urine Porphyrins
- Coproporphyrin (copro) is a general marker for
overall toxic metal burden. It is seen elevated
in the presence of mercury, lead and arsenic - Precoproporphyrin (preco) an atypical porphyrin
that only appears in the presence of mercury - Heptacarboxyporhyrin and uroporphyrin is high on
exposure to pesticides, PCBs, arsenic and
aluminum - (Woods, 2005)
73Urine Porphyrins
- Children with autism have significantly higher
levels of copro and preco porphyrins compared to
controls (Nataf, 2006 Geier, 2006) - Nataf also found that the severity of autistic
symptoms correlated with the copro level, and
that children with autism and seizures had the
highest copro levels. - Urine porphyrin levels decrease with chelation
(Pingree, 2001)
74(No Transcript)
75Urine Porphyrins(how/when I use the test)
- I only send to Dr Natafs lab in France. They are
the only commercial lab that has ranges for
children and that autistic children has been
studied at. The large US labs are not calibrated
to test for levels under that which is seen in
genetic porphyrin diseases which produce much
higher porphyrin levels - I prefer using the chelation challenge test, as
it also tells me if the chelation agent/route of
administration is working, not just if the metals
are present. - I order this test for
- families who do not wish to expose their
children to a chelation agent unless there is
proof of metals. - If chelation challenge tests are negative but we
still suspect metals are present - Once chelation challenge tests are negative after
cycles of chelation, if we still suspect metals
are present

84Neurotoxicity of Thimerosal in Human Brain
Cells is Associated with Glutathione Depletion
Protective Effect of Cysteine or Glutathione
Supplementation
- WORKING HYPOTHESIS
-
- Ethyl mercury in Thimerosal binds to cysteine
thiol (SH) groups on intracellular proteins and
inactivates function. - The cysteine-rich antioxidant, glutathione,
binds mercury and protects essential proteins
from functional inactivation. - The neurotoxicity of Thimerosal is associated
with depletion of glutathione, the major
intracellular antioxidant.

92So, Why is this happening?
- Certain toxins such as mercury can inhibit the
enzymes of this pathway. - Dr James has looked at the DNA sequences that
code for the proteins that make up these enzymes
and has found that autistic children have up to 3
times as many single DNA mutations
(polymorphisms, SNPs) as do children without
autism - We have identified these SNPs in children with
other neurodevelopmental disorders

- All reported side effects faded upon stopping
therapy - Most parents chose to resume therapy b/c
benefits outweighed the side-effects
97Oxalates
- Oxalates are small carbon and oxygen containing
molecules that are found in certain types of
fruits and vegetables. Also most nuts and seeds
have oxalates. - For most people, oxalates in the diet are not
absorbed in great amounts into the bloodstream.
They are usually metabolized by intestinal flora
and excreted in the feces. - In the presence of intestinal inflammation and
leaky gut, larger amounts of oxalates can get
into the bloodstream and be transported to
tissues - Under certain conditions they can crystallize and
become deposited in tissues. The crystals can
grow and become stones (kidney stones are calcium
oxalate) - When lodged in tissues, these crystals can
produce irritation and pain.
98Oxalates
- Oxalates seem to accumulate more in conditions of
glutathione deficiency and oxidative stress. - Vitamin B6 (pyridoxine) is a necessary cofactor
for enzymes that help prevent the formation of
oxalates - When sulfur is deficient, it becomes extremely
difficult to keep the body from making excess
oxalates. - High oxalates are associated with certain
conditions like vulvodynia, prostatitis,
irritable bowel syndrome, fibromyalgia,
interstitial cystitis, and skin sensitivity. Some
people may get a sense of urinary urgency and
frequent urination, and sometimes the patient
would have trouble urinating (Solomon, VP
Foundation) - High oxalates are often seen in patients with
recurrent/resistant yeast infections and glycine
intolerance.
99Testing for High Oxalates
- There is no perfect test right now.
- Urine testing is most often used. If high values
are seen then this is a strong indicator, but
people secrete oxalates in their urine at
different times of the day (it may be most
accurate to collect multiple urine specimens
during the day), and relative to food intake so
there can be false negatives. - Great Plains Lab full organic acid test reports a
spot oxalic acid value. They also report other
substances that are high when there are oxalate
issues glyceric and glycolic acid - Quest Labs has both random and 24 hour urine
oxalate tests, both as an individual value as
well as relative to oxalate. I usually get 24
hour collection with oxalate.
100Treating High Oxalates
- The low oxalate diet. Full information can be
found at several sources - Yahoo Group Trying_Low_Oxalates
-
101Treating High Oxalates
- The Low Oxalate Cookbook is published by the
Vulvar Pain Foundation, contains over 250
recipes. - The book has lists of foods with actual amount of
oxate per serving of a food. - Aim to keep oxalate intake down to under 40-60mg
oxalate a day. - Food Lists and summary can be found on Medical
Topics section of my webpage - Probiotics VSL3 1/2 to 1 capsule daily or ¼
to ½ packet of the unflavored powder daily - Reduce vitamin C to 250mg or less a day,
including foods (oxalates can be converted to
vitamin C) - Calcium citrate supplementation - given with
meals to help bind and excrete the oxalates.
102Elevated Male Hormones/Androgens
- Several studies have demonstrated that children
with Autism Spectrum Disorders have elevated
androgens, including testosterone,
dihydrotestosterone, androstendione and DHEA
(Torjman, 1997 Knickmeyer, 2005 Geier,2006) - Although not exclusive, increased androgens have
been associated with increased masturbation and
genital rubbing, aggressiveness, hyperactivity,
self-stimming, and increased body hair (legs and
back), - Elevations have been seen in male and female
patients - I use LabCorp for my testing. They have the most
specific reference ranges for both sex and age of
patient.
103Elevated Male Hormones/Androgens
The enzyme that converts DHEA to DHEA-S (storage
hormone) is sulfotransferase, which is
glutathione dependant. When this enzyme is not
working, there is a build up of DHEA which then
gets sent to androstenedione and then testosterone
104Treating elevated Androgens
- Geier Lupron.
- belongs to a class of drugs called
gonadotropin-releasing hormone (GnRH) agonists. - It is used to decrease the bodys production of
specific hormones, natural chemicals that
influence the behavior of certain cells. Because
Lupron Depot can reduce the production of both
male and female hormones, it is used to treat
specific conditions in men, women, and children
(www.lupron.com) - Bradstreet Spironolactone,
- a potassium sparing diuretic, also has action of
blocking the receptor for dihydrotestosterone. - Androgen levels should not go down with this
treatment, but the effects of the hormone are
blocked.
105Treating elevated Androgens
- Berger (VERY NEW)
- Glycyrrhizin the active ingredient in licorice
root - decreases testosterone level by inhibiting the
enzyme which converts of 17-OH progesterone to
DHEA (Armanini, 1999) - Inhibits the enzyme that converts Androstendiaone
to Testosterone (Fukui, 2003). - High doses can affect blood pressure and fluid
retention, but doses lt 0.2mg/kg/d should not
cause these side effects (van Gelderen, 2000). - Current trials underway.
- In addition to monitoring the androgens, also
monitoring cortisol, ACTH and blood pressure

107Risperdal
- 1st medicine specifically approved for Autism
- For use in children with aggressiveness, extreme
hyperactivity - Specific weight dosing is known
- Effects are immediate, often seen the first day
- Pretty easy to titrate for affective dose
- Pretty easy to get kids off of once the
underlying reason is uncovered - Fewer incidences of side effects compared to
other psychotropic drugs
108Vaccine Update(time permitting)
109Varicella / Chicken Pox Vaccine
- Brand Name Varivax
- my initial concerns over long term protection
- when first released, one of the main talking
points was that each shot saved the system 42
. - now we are seeing failures
- Either it didn't take in the first place
- or long term protection was not conferred
- now 2nd dose is being recommended between 4-6
years old - My recommendation as morbidity increases with
age, if not with vaccine or definitive disease by
age 11, get titer to see if immune and if not,
consider the vaccine
110Influenza Vaccine
- No guarantee that the strain of flu one is
exposed to is 1 of the 3 that are in the vaccine - Thimerosal-free shot now available but not
guaranteed. Must view package insert - Nasal spray
- now available for children 5 and older
- is mercury-free
- is a live virus
- makes some sense, as it uses the natural lines of
defense to convey immunity - Contraindicated for those who likely could
benefit from it the most.those with asthma and
immunodeficiency - Article at www.wholisticpeds.com
111HPV/Cervical Cancer/Genital Warts
- Brand Name Gardasil
- Not contagious disease, except for sexual
contact. Raises ethical questions. - Not protecting against all strains of HPV
- protects against 70 of strains causing cervical
cancer - protects against 90 of strains causing cervical
warts - being recommended for females 11-26 y/o, but can
be given as early as 9 y/o - for me, it is to early to assess safety, as often
less common side effects are not seen until large
groups of people are vaccinated such as was seen
with..
112Rotavirus
- 1st vaccine, called RotaShield was made available
in the late 1990s deemed safe in pre market
studies - Then within the first year of widespread use
there were at least 100 cases of intussusception,
an acute form of bowel obstruction - The vaccine was pulled in 1999
- 2006, a new, safer vaccine was introduced,
called RotaTeq. - So far, 28 cases reported so far, about half of
them occurred within 21 days of vaccination and
16 of the infants had to have surgery. - Lactobacillus has been demonstrated to
significantly shorten the length of time with
diarrhea (Shornikova, 1997) and frequency of
stools (Van Neil, 2002)
113Hyperbaric Oxygen Therapy
- Definition A therapeutic modality that employs
the application of pressures greater than ambient
atmospheric pressure, at oxygen levels greater
than atmospheric oxygen (gt21) - Traditional HBOT a hard walled chamber that
exposes the patient to a maximum of 3ATA
(monoplace-1 patient) or 6ATA (multiplace - gt1
patient) at 100 oxygen - Mild HBOT (mHBOT) - a soft walled chamber that
exposes the patient to a maximum of 1.3ATA and
lt100 oxygen
114Hyperbaric Oxygen TherapyLaws of Physics
- Henrys Law - the amount of a gas absorbed by a
liquid is in proportion to the pressure of the
gas above the liquid, provided that no chemical
action occurs. - Boyles Law - at a constant temperature, the
volume and the pressure of a gas are inversely
proportional. In other words, a gas will compress
proportionately to the amount of pressure exerted
on it. - Examples of these laws
- a bottle of soda
- A scuba diver
115Hyperbaric Oxygen TherapyHistory
- In 1662, British Physician Dr. Henshaw first used
compressed air in an attempt to treat pulmonary
disease. His first chamber was called the
Domicilium. Chamber pressure was either raised
or lowered with organ bellows - In 1879, French surgeon Fontaine created a mobile
chamber. He was able to increase the amount of
oxygen carried in the blood during the
administration of nitrous oxide anesthesia. This
prevented blood oxygen levels from decreasing,
which typically happened from surgical
anesthesia - In 1921 Cunningham constructed a 20 meter round
ball that was the largest Hyperbaric Chamber ever
built. It contained a smoking lounge, dining
facilities, rich carpeting, and private quarters.
116Hyperbaric Oxygen TherapyCunninghams Sanitarium
-1921
- Later it was scraped for metal during World War
II.
117Hyperbaric Oxygen TherapyHistory
- In 1934, US Naval Submarine Officer, Dr. Behnke
proposed using oxygen plus recompression for
Decompression Sickness (the bends). This
information was ignored until 1967 - In 1955, Dutch thoracic surgeon, Dr. Boerma
removed the red blood cells from pigs and found
they could survive with oxygen dissolved in
plasma by use of hyperbaric Oxygen. - In 1961 Danish Dr. Brummelkamp, Published on the
ability of HBOT to inhibit the growth of
anaerobic bacteria - organisms that live where
there is low or no oxygen, such as gangrene or
tetanus. - In June 2006 Tampa Pediatrician David Berger
obtained his first mHBOT chamber, getting a
second one the month later. The world has never
been the same since.

120Hyperbaric Oxygen TherapyProposed Mechanisms of
ActionRossignol DA, Hyperbaric oxygen therapy
might improve certain pathophysiological findings
in autism. Med Hypotheses (2006)
- Differing levels of pressure and oxygen were used
in the various studies that are discussed - Some may be at pressures that are not being
recommended for children with Neurodevelomental
disorders
121Hyperbaric Oxygen TherapyProposed Mechanisms of
Action
- Cerebral Hypoperfusion and Hypoxia in Autism
- Multiple studies have shown hypoperfusion to
areas of the brain of children with autism,
especially the temporal lobes. (Rye, 1999
Zilbovicius, 2000 Ohnishi, 2000) - The low blood flow was more profound the older a
child is. (Wilcox, 2002) - Autistic children often do not increase their
cerebral blood flow when doing tasks and when
listening and trying to speak, as seen in
neurotypical children. (Critchley 2000, Allen
2003). - Decreased blood flow to the thalamus as seen on
SPECT scans has been associated with repetitive
and self-stimming behaviors (Starkstein, 2000) - Decreased blood flow to Wernickes and Brodmanns
areas (speech areas of the brain) has been
associated with decreased auditory processing
(Bodaert, 2002) and language development
(Wilcox, 2002)
122Hyperbaric Oxygen TherapyProposed Mechanisms of
Action
- Treating Hypoperfusion with HBOT
- HBOT may overcome the effects of the
hypoperfusion by providing the brain with more
oxygen (Sheffield, 1976 Neubauer, 1998) - HBOT may increase new blood vessel growth
(Al-Waili, 2006) - Hypoperfusion may be due to inflammation.
Inflamed vascular cells can lead to diminished
blood flow, and inflammation in tissue prevents
maximal uptake of oxygen by cells - HBOT can increase the distance that Oxygen can
travel between cells (Williams, 1997) - Increased blood flow to the brain also means
increased blood flow from the brain, potentially
increasing the flow of toxins away from the
brain. This could bring a synergistic effect with
chelation.

125Hyperbaric Oxygen TherapyProposed Mechanisms of
Action
- Neuroinflammation and Autism
- Of recent, several studies have demonstrated
evidence that children with autism have increased
neuroinflammation. - Increased inflammatory cells and pro-
inflammatory chemical mediators (cytokines) have
been found in the CSF of Autistic Children
(Weizman, 1982 Vargas, 2005). - Increased brain auto-antibodies have been
demonstrated in children with Autism (Connolly,
1999 Singh, 1997 Vojdani, 2002 Singer, 2006)
126Hyperbaric Oxygen TherapyProposed Mechanisms of
Action
- Gastrointestinal Inflammation and Autism
- A subset of children with Autism have
demonstratable inflammation of their stomach,
small intestine and colon (Furlano, 2001
Uhlmann, 2002 Balzola, 2005 Wakefield, 2005) - Both inflammatory cell and cytokines (TNF-?,
IL-1?, IL-6) have been seen in increased amounts
in the gastrointestinal lining in some children
with Autism (Jyonouchi, 2001 Ashwood, 2003
2004) - Many children with autism have increased serum
antibodies directed against casein and gluten
based peptides (Vojdani, 2003 2004)
127Hyperbaric Oxygen TherapyProposed Mechanisms of
Action
- Treating Inflammation with HBOT
- HBOT had been demonstrated to have
anti-inflammatory affects on tissues (Al-Waili,
2006) - HBOT can decrease the production of the
cyctokines that are pro-inflammatory such as IL-6
and IL-1(Weisz, 1997) and TNF-?, (Yang, 2006) - HBOT can increase the production of cytokines
that decrease inflammation such as IL-10 (Buras,
2006) - HBOT has been shown in animal studies to reduce
symptoms and inflammation of arthritis (Warren,
1979) and peritonitis (Tokar, 2003) - There is evidence that HBOT can facilitate
remission for non-responsive Crohns Disease
(Brady, 1989 Columbel, 1995) and Ulcerative
Colitis (Buchman, 2001 Gurbuz, 2003)
