The Gluten Free and Casein Free (GFCF) Diet: A Double Blind, Placebo Controlled Challenge Study

19 May

This study has been a long time coming. I’ve been hearing about it for years: a study on the GFCF diet for autistics. The study, led by Dr. Susan Hyman of the University of Rochester, has been on clinicaltrials.gov since August 2004.

The concept was fairly simple: get children on a GFCF diet. Monitor their diet for proper nutrition. Once the child is on the diet, give the child small snacks, some with small amounts of gluten or casien or both and some without. Track behaviors. The parents and children and most of the researchers were “blind” to which snacks had the gluten and or casien.

The results, as Kev has already blogged, are finally in. The result: autistic children, in general, are not affected by gluten or casien. The “autism is just a leaky gut” theory was never very well supported.

Does this mean that no autistic children have sensitivities to gluten or casien? Hardly. Being autistic is not a shield against food sensitivities. What this does tell us is that autism is not caused by these nutrients.

The abstract is up on the IMFAR website:

Background: Approximately 1/3 of children with ASD receive dietary interventions. While families report dramatic clinical effects, two prior trials do not confirm these positive outcomes. Neither examined nutritional sufficiency or controlled for other interventions. This study was undertaken to examine the behavioral and physiologic effects of the GFCF diet and assess its nutritional adequacy.
Objectives: To evaluate the nutritional adequacy, physiological effects, and efficacy of the GFCF diet on symptoms of ASD using randomized double blind placebo controlled challenges in preschool children with ASD. Methods: ADI-R/ADOS positive children ages 30-54 months receiving at least 10 hours/week of early intensive behavioral intervention (EIBI) were recruited. They were screened for milk/wheat allergies, celiac disease, and anemia/iron status by RAST, TTG and CBC/ferritin respectively. After a strict GFCF diet for at least 4 weeks, they received weekly, grouped, randomized double blind challenges containing either 20 g wheat flour, 20 g evaporated milk, both, or neither on three separate occasions over 12 weeks . The challenges appeared identical and were similar in taste and texture. Laboratory monitoring and BMI recording occurred at baseline, 6,18,and 30 weeks. Behavioral data was collected at these times plus the day before then 2 and 24 hours after each challenge, Measures included: Bristol Stool Scale, Sleep Diaries, Actigraphy, Conners Abbreviated Rating Scale, and Target Symptoms Scale. Ritvo Freeman Real Life Rating Scales (RFRLRS) were recorded at 2 and 24 hours post challenge. Challenges occurred only if measures were at baseline levels. Data were analyzed by group and for individual children comparing baseline with 4 weeks on diet and then pre/post challenges.
Results: Twenty one children were recruited. Two were excluded for positive TTG, one for anemia. Four additional children were unable to establish the diet or left EIBI. Group data on the 14 successful participants (43.5 months, range 35-54 ; 12 males) demonstrated no statistical change in frequency or quality of stools, sleep, actigraphy for activity, or parent/teacher/observer scores of attention/activity for baseline/ diet or in pre/post challenge ratings. The group RFRLRS data 2 hours post challenge were higher after placebo than after challenges of casein (p=.013), gluten (p=0.024) or gluten + casein (p= 0.021). These differences were not present 24 hours post challenge. Single case analysis will be presented. All children were maintained within acceptable ranges for micro/macronutrients with intense weekly dietary monitoring.
Conclusions: This is the first study to examine the behavioral effects of a nutritionally monitored GFCF diet on attention, sleep, stool pattern, and core symptoms of ASD. While no favorable effects of the GFCF diet on attention, sleep and stool patterns were identified in group analyses, such effects may occur for individuals or for subgroups of children (e.g. with significant GI disease), providing the basis for positive anecdotal reports. Future studies need to address the potential effects of nutrition on behavior in children with ASD and be powered to evaluate subtle changes in core symptoms.

GFCF of no benefit

19 May

This post is from Eureka Alert

A popular belief that specific dietary changes can improve the symptoms of children with autism was not supported by a tightly controlled University of Rochester study, which found that eliminating gluten and casein from the diets of children with autism had no impact on their behavior, sleep or bowel patterns.

The study is the most controlled diet research in autism to date. The researchers took on the difficult yet crucial task of ensuring participants received needed nutrients, as children on gluten-free, casein-free diets may eat inadequate amounts of vitamin D, calcium, iron and high quality protein. Unlike previous studies, they also controlled for other interventions, such as what type of behavioral treatments children received, to ensure all observed changes were due to dietary alterations. Past studies did not control for such factors. And although no improvements were demonstrated, the researchers acknowledged that some subgroups of children, particularly those with significant gastrointestinal (GI) symptoms, might receive some benefit from dietary changes.

“It would have been wonderful for children with autism and their families if we found that the GFCF diet could really help, but this small study didn’t show significant benefits,” said Susan Hyman, M.D., associate professor of Pediatrics at Golisano Children’s Hospital at the University of Rochester Medical Center (URMC) and principal investigator of the study which will be presented Saturday (May 22) at the International Meeting for Autism Research in Philadelphia. “However, the study didn’t include children with significant gastrointestinal disease. It’s possible those children and other specific groups might see a benefit.”

In response to widespread parent-reported benefits, URMC initiated the trial in 2003 to scientifically evaluate the effects of the gluten-free and casein-free diet, which eliminates wheat, rye, barley and milk proteins. Parent observation has played an important role in earlier treatment discoveries in children with autism, such as melatonin’s benefits for sleep.

Hyman’s study enrolled 22 children between 2 ½- and 5 ½-years-old. Fourteen children completed the intervention, which was planned for 18 weeks for each family. The families had to strictly adhere to a gluten-free and casein-free diet and participate in early intensive behavioral intervention throughout the study. Children were screened for iron and vitamin D deficiency, milk and wheat allergies and celiac disease. One child was excluded because of a positive test for celiac disease and one was excluded for iron deficiency. Other volunteers who were excluded were unable to adhere to the study requirements. The children’s diets were carefully monitored throughout the study to make sure they were getting enough vitamin D, iron, calcium, protein and other nutrients.

After at least four weeks on the strict diet, the children were challenged with either gluten, casein, both or placebo in randomized order. They were given a snack once weekly with either 20 grams of wheat flour, 23 grams of non fat dried milk, both, or neither until every child received each snack three times. The type of snack was given in randomized order and presented so that no one observing – including the family, child, research staff and therapy team – knew what it contained. The snacks were carefully engineered to look, taste and feel the same, which was an exercise in innovative cooking. In addition, the nutrition staff worked closely with the families to make a snack that met their child’s preferences. Casein was disguised in pudding, yogurt or smoothies and gluten in banana bread, brownies, or cookies depending on the child’s food preferences.

Parents, teachers and a research assistant filled out standardized surveys about the child’s behavior the day before they received the snack, at two and 24 hours after the snack. (If the child’s behavior wasn’t usual at the scheduled snack time, the snack would be postponed until the child was back to baseline.) In addition, the parents kept a standard diary of food intake, sleep and bowel habits. Social interaction and language were evaluated through videotaped scoring of a standardized play session with a research assistant.

Following the gluten and casein snacks, study participants had no change in attention, activity, sleep or frequency or quality of bowel habits. Children demonstrated a small increase in social language and interest in interaction after the challenges with gluten or casein on the Ritvo Freeman Real Life Rating Scale; however, it did not reach statistical significance. That means because of the small difference and the small number of participants in the study, the finding may be due to chance alone.

The investigators note that this study was not designed to look at more restrictive diets or the effect of nutritional supplements on behavior. This study was designed to look at the effects of the removal of gluten and casein from the diet of children with autism (without celiac disease) and subsequent effect of challenges with these substances in a group of children getting early intensive behavioral intervention.

Hyman said, “This is really just the tip of the iceberg. There are many possible effects of diet including over- and under-nutrition, on behavior in children with ASD that need to be scientifically investigated so families can make informed decisions about the therapies they choose for their children.”

Prevalence Rates of Autism Spectrum Disorders Among the Old Order Amish

17 May

One of the topics that comes up over and over online is “The Amish don’t vaccinate” and “the Amish don’t have autism”. Both statements are incorrect. The Amish have no religious prohibition against vaccination and they do have autism.

The question of autism amongst the Amish has been studied and is being presented at the IMFAR autism conference this week. The paper,
Prevalence Rates of Autism Spectrum Disorders Among the Old Order Amish, demonstrates a preliminary prevalence of 1 in 271 as the prevalence of autism amongst Amish children in two Amish communities: Holmes County, Ohio and Elkhart-Lagrange County, Indiana.

J. Haines , Center for Human Genetics Research, Vanderbilt University, Nashville, TN
M. Pericak-Vance , Hussman Institute for Human Genomics, University of Miami Miller School of Medicine, Miami, FL
Background:

The prevalence rate of Autism Spectrum Disorders (ASD) appears to be steadily increasing. The latest report from the Center for Disease Control estimates the rate of ASD is 1 in 91 children (Kogan, 2009), up from 1 in 150 in 2007. Understanding the seeming changes in ASD prevalence require careful exploration of genetic and environmental factors. A method that has proven useful in dissecting the etiology of complex diseases is the study of isolated populations. One population isolate that has been studied extensively is the Amish, with well over 250 genetic studies. Expanding studies of autism to the Amish may provide important information about etiology. A crucial first step in this process is a feasibility study to determine ASD prevalence rates in this population.

Objectives:

This study presents preliminary data on the estimated prevalence of ASD among the Amish in two Amish dominant counties as part of a larger epidemiological study. All children between ages 3 to 21 in those counties will be screened for the presence of an ASD.

Methods:

Screening occurred in, two of the largest Amish communities in the United States. Trained clinicians ascertained door to door using a published Amish Directory as a guide. Families were approached and asked to participate in a brief interview regarding their children. Two primary screening instruments were used: the Social Communication Questionnaire (SCQ) and the DSM-IV-TR Checklist (a tool created by the authors). A Vaccination History and a brief family history including questions specific to the ASD phenotype were also taken. Children screening positive on either the SCQ or DSM-IV-TR Checklist were seen for a more comprehensive clinical evaluation by two licensed psychologists. This evaluation included the Autism Diagnostic Observational Schedule (ADOS) and Autism Diagnostic Interview (ADI).

Results:

From September 2008 to October 2009, 1899 Amish children were screened in the two Amish communities. A total of 25 children screened positive for ASD on either the SCQ or the DSM-IV-TR checklist. A total of 14 screened positive for ASD on both screeners. Of those 25 children, 14 were evaluated and seven children were confirmed as having a diagnosis of ASD using the ADI and/or ADOS, and clinical judgment. Interestingly, four of the seven only met ASD criteria on the ADOS but not the ADI. Three of the four who were not diagnosed by the ADI only missed criteria on the Behavioral Domain, which may be attributable to the reporting style of Amish caregivers.

Conclusions:

Preliminary data have identified the presence of ASD in the Amish community at a rate of approximately 1 in 271 children using standard ASD screening and diagnostic tools although some modifications may be in order. Further studies are underway to address the cultural norms and customs that may be playing a role in the reporting style of caregivers, as observed by the ADI. Accurate determination of the ASD phenotype in the Amish is a first step in the design of genetic studies of ASD in this population.

Storm in a teacup

15 May

A piece from the Philadelphia Inquirer demonstrates how various vaccine scares begin.

Using powerful new DNA technology, Delwart’s San Francisco team detected fragments of a pig virus in GlaxoSmithKline’s Rotarix, which protects babies from a diarrhea-causing infection. The pig virus is common in pork products and is not known to cause disease in animals or humans.

…

We expected to reassure; we ended up not reassuring,” Delwart, a virologist with the Blood Systems Research Institute, said this week. “We ended up creating quite a bit of a storm.

Yet of course the usual suspects used this total non-entity of a story to further their own anti-vaccine agenda:

This “is an important wake-up call for industry and government,” said Barbara Loe Fisher, president of the National Vaccine Information Center.

How exactly isn’t explained. This is after all a story where a vaccine carries a component that *is not known to cause disease* . Neither the FDA or the European Health Agency said the vaccines containing the component shouldn’t be used. As Paul Offit said:

“You could apply this new technology to things gummed by a 6-month-old – a Cheeto, a piece of apple – and find much worse” microbes than the pig virus, Offit said. “How does it help to find things that are not known to be harmful? It’s like taking thimerosal out of vaccines. Has that made vaccines safer? No.”

Or more dangerous.

We *have* to start getting over our collective heebie-jeebies every time something perfectly safe is found in a vaccine and start realising that the people who are advocating that we _do_ have an attack of the heebie-jeebies are those who have a single item agenda – promoting anti-vaccineism.

Mirror Neurons theory of autism refuted by fMRI study

14 May

Mirror neurons come up a lot in autism research. Perhaps the mirror neuron theory is, as one researcher put it, exaggerated with little evidence to support it.

This is discussed in the Simons Foundation sfari blog. Also, the authors have made a video to discuss the mirror neuron theory and their recent experiment (again, I found this on the sfari blog). I apologize that it is not closed captioned.

I don’t want to just rephrase what has been said in these two presentations, so I will refer you to the sfari blog and the video from the researchers.

International Meeting for Autism Research abstracts are online

14 May

INSAR, the International Society for Autism Research, hosts a conference each year. IMFAR, the International Meeting for Autism Research is the largest autism conference held.

IMFAR is being held in Philadelphia, Pennsylvania (US) this year, May 20 to May 22nd. The conference abstracts give you an idea for the latest research trends.

You can search the program online. Alternatively, you can download the program or the abstracts as pdf’s.

Autistic researcher Michelle Dawson is listed as the anchor author on a study, Perception in Autism, 2006 – 2009: Updating the Enhanced Perceptual Functioning Model.

Dr. Lisa Croen from Kaiser Permanente has a paper on whether maternal infections are linked to autism. Maternal Infection During Pregnancy and Risk of Autism Spectrum Disorders. They find an increased risk due to bacterial infections in the second half , similar to results from a recent paper from Denmark.

Dr. Gail Windham’s group has a study, Autism and Distribution of Hazardous Air Pollutants at Birth in Southern California. This is a follow on to their study of Hazardous Air Pollutants in Northern California (Autism Spectrum Disorders in Relation to Distribution of Hazardous Air Pollutants in the San Francisco Bay Area) which is often cited in support for the mercury-causation hypothesis. The conclusion to the news study states: ” Examining HAPs in another region of California with higher concentrations and larger numbers did not replicate the original results. Metals as a group were not associated, but instead aromatic solvents yielded the highest risks”

Prof. David Mandell of the University of Pennsylvania has large number of papers. I follow his work since one of his areas involves under-represented groups such as minorities and adults. For example, one of his papers is Services Utilized by Adults with Autism Spectrum Disorders.

There are a number of papers discussing regression. For example, about 33% of autistic children underwent some form of regression in this study. Dr. Swedo’s team at NIMH looked closer at regression in autistic children in Regression Histories in Young Children with Autism: Timing and Associations Out of 185 children whose parents were interviewed:

Among the 80 cases with significant regression, parents of 26 children indicated physical illness/medical issues may have been related to loss of skills, and 21 responses indicated an associated psychosocial stressor (in 7 of these cases, both illness and psychosocial stressors were reported). However, only 8 reports clearly indicated a sudden loss of skills. Five of the 8 cases with sudden loss included both loss of language loss and social engagement/responsiveness. Two of the sudden loss cases were reported to be associated with a physical illness/medical issue and 3 were reported to be associated with a psychosocial stressor (with 1 reported to have both).

Obviously, there is more. Much more. I’m still working my way through the program book. D’oC will be attending IMFAR and blogging here at LeftBrainRightBrain with support from the Autism Science Foundation.

Trends in US autism research funding: more money going to clinical and translational research

11 May

Where money is being spent on autism research is changing. Basic science, which still gets most of the money, is decreasing and clinical and translational research is increasing.

If you are like me, you have to look up “translational research”. From the link above, “To improve human health, scientific discoveries must be translated into practical applications.” I.e. this is research to “translate” basic findings into practical applications.

This was analyzed in a paper published last year by a team at Stanford University in California:

Trends in US autism research funding.

Singh J, Illes J, Lazzeroni L, Hallmayer J.

Stanford Center for Biomedical Ethics, Center for Integration of Research on Genetics and Ethics, Stanford University, Palo Alto, CA, USA.
Abstract

This study shows that the number of autism research grants funded in the US from 1997 to 2006 significantly increased 15% per year. Although the majority of projects were concentrated in basic science (65%) compared to clinical (15%) and translational research (20%), there is a significant decrease in the proportion of basic research grants per year and a significant increase in the proportion of translational projects per year. The number of translational projects funded by the National Alliance for Autism Research and Cure Autism Now increased significantly, whereas the number of clinical projects significantly increased for the National Institutes of Health. In conclusion, this study demonstrates the shifting landscape of autism research from basic science to clinical and translational research.

The study analyzed grants up to 2006. This is before the increase in funding through the Combating Autism Act. The current budget for IACC proposes projects is about $220,000,000 per year, with a total for all years of over one billion dollars. Over $230 million are dedicated to “Which treatments and interventions will help?”

As noted here on LeftBrainRightBrain, funding levels for areas such as environmental causation have increased, overtaking genetic only causation research in funding levels.

No Link Between Childhood Infections, Autism

10 May

One of the theories posited about autism causation is that childhood infections can result in autism. A recent study from the Arhus, Denmark, explores this by checking how often children are admitted to the hospital for infectious diseases. Given that maternal infections do appear to be associated with a greater risk of autism, the idea of childhood infections is worth considering. I would add that the attention to mitochondrial disorders and autism that was high in the past couple of years would also suggest this is a valuable area to consider.

Here is the abstract:

OBJECTIVE: To investigate the association between hospitalization for infection in the perinatal/neonatal period or childhood and the diagnosis of autism spectrum disorders (ASDs). DESIGN: A population-based cohort study. SETTING: Denmark. PARTICIPANTS: All children born in Denmark from January 1, 1980, through December 31, 2002, comprising a total of 1 418 152 children. EXPOSURE: Infection requiring hospitalization. MAIN OUTCOME MEASURE: The adjusted hazard ratio (HR) for ASDs among children hospitalized for infection compared with other children. RESULTS: A total of 7379 children were diagnosed as having ASDs. Children admitted to the hospital for any infectious disease displayed an increased rate of ASD diagnoses (HR, 1.38 [95% confidence interval, 1.31-1.45]). This association was found to be similar for infectious diseases of bacterial and viral origin. Furthermore, children admitted to the hospital for noninfectious disease also displayed an increased rate of ASD diagnoses (HR, 1.76 [95% confidence interval, 1.68-1.86]), and admissions for infection increased the rate of mental retardation (2.18 [2.06-2.31]). CONCLUSIONS: The association between hospitalization for infection and ASDs observed in this study does not suggest causality because a general association is observed across different infection groups. Also, the association is not specific for infection or for ASDs. We discuss a number of noncausal explanatory models.

Autistic children *are* admitted to the hospital for infectious diseases more often than the rest of the population. But, in general autistic children are admitted to the hospital more often than the rest of the population.

Bloomberg Businessweek discussed this paper in No Link Between Childhood Infections, Autism. They interviewed Dr. Andrew Zimmerman of the Kennedy Krieger Institute. Dr. Zimmerman concurred with the conclusions of the paper:

“Yes, there is an increased rate of hospitalization preceding the diagnosis of autism, but it doesn’t support a causal relationship between autism and infections,” Zimmerman said.

This is significant, in my view. Dr. Zimmerman is one of the doctors who treated Hannah Poling (the young girl whose case was conceded by the Department of Health and Human Resources in the vaccine court, sparking the public interest in the subject).

It is also worth noting that the study considered specific infections. From the Bloomberg/Newsweek story:

And the researchers could point to no particular infection that upped the risk.

They therefore conclude that childhood infections cannot be considered a cause of autism.

“We find the same relationship between hospitalization due to many different infections and autism,” noted lead study author Dr. Hjordis Osk Atladottir, of the departments of epidemiology and biostatistics at the Institute of Public Health, University of Aarhus in Denmark. “If there were a causal relationship, it should be present for specific infections and not provide such an overall pattern of association.”

Maternal Infection Requiring Hospitalization During Pregnancy and Autism Spectrum Disorders

4 May

One known possible environmental cause of autism is rubella infections in the mother during a pregnancy. This can lead to a condition called “Congenital Rubella Syndrome”. Many with CRS have very significant disabilities, including intellectual disablity and autism.

The epidemiological team at Aarhus, Denmark, has taken this one step further and looked at maternal infections in general. What they found was that viral infections in the first trimester and bacterial infections in the second trimester are associated with a roughly 3 times greater risk of autism for the child. The infections noted were severe enough to warrant hospitalization.

Maternal Infection Requiring Hospitalization During Pregnancy and Autism Spectrum Disorders.
Atladóttir HO, Thorsen P, Ostergaard L, Schendel DE, Lemcke S, Abdallah M, Parner ET.

Exposure to prenatal infection has been suggested to cause deficiencies in fetal neurodevelopment. In this study we included all children born in Denmark from 1980, through 2005. Diagnoses of autism spectrum disorders (ASDs) and maternal infection were obtained through nationwide registers. Data was analyzed using Cox proportional hazards regression. No association was found between any maternal infection and diagnosis of ASDs in the child when looking at the total period of pregnancy: adjusted hazard ratio = 1.14 (CI: 0.96-1.34). However, admission to hospital due to maternal viral infection in the first trimester and maternal bacterial infection in the second trimester were found to be associated with diagnosis of ASDs in the offspring, adjusted hazard ratio = 2.98 (CI: 1.29-7.15) and adjusted hazard ratio = 1.42 (CI: 1.08-1.87), respectively. Our results support prior hypotheses concerning early prenatal viral infection increasing the risk of ASDs.

Transcripts of the Rashid Buttar hearings–a peek at how alternative medicine treats autistic children

4 May

Dr. Rashid Buttar was recently reprimanded by the North Carolina Medical Board. The reprimand was basically a slap on the wrist. A weak one at that.

The inquiry into Dr. Buttar discussed a number of his patients. One, patient E, was autistic. Dr. Buttar has allowed us to read about his practice by posting the testimony from the hearings.

This, from the opening statements for Dr. Buttar’s hearing:

Patient E is a pattern-in-practice patient. Patient E is an eight-year-old school girl who is severely autistic. Her mother contacted the Board after receiving a solicitation from Dr. Buttar to support him in this matter.
Like the ?- like the cancer patients, Patient E’s mother came across information that Dr. Buttar could help her child’s autism. And without ever seeing the doctor, without ever traveling to North Carolina, Patient E was sent a kit to ?- to basically self-administer a chelation therapy on her own daughter.
And when things started going ?- deteriorating for Patient E, Patient E’s only interaction with Dr. Buttar was through his nurse practitioner or other staff members in his office.
And the nurse practitioner who essentially, from the medical records, as you will see, made all decisions about the treatment and diagnosis of this child’s autism across state lines without personally seeing the patient, has no formal training in autism or oncology, much like Dr. Buttar who does not have any formal training in oncology or autism.
Yet, nonetheless, they convinced Patient E’s mother to take the child off of her medication so that he can apply a transdermal chelation cream on the child. A cream, not so coincidentally, that is developed and invented and sold directly by Dr. Buttar to his patients.
The mother did as instructed and took her daughter off her medication and applied Dr. Buttar’s transdermal chelation cream. Her daughter began to deteriorate. The child began to have violent tantrums. She couldn’t leave the house or attend school. During the weeks and months as the child deteriorated, Dr. Buttar never followed the child.
And when the mother did not get a satisfactory responses to her concerns, she called the office, made an appointment to see Dr. Buttar and drove her family to North Carolina. However, when she got to North Carolina, she did not see Dr. Buttar, only the nurse practitioner.
And the result of that meeting was that the nurse practitioner attempted to convince the patient ?- the patient’s mother that the child needed to be converted to a more aggressive intravenous form of chelation therapy.
The evidence will show that Patient E’s situation mirrors that of the other patients. Little or no physician involvement with the patient. Patients are seen primarily, if not exclusively, by the nurse practitioner. The patients have serious illnesses and Dr. Buttar and his nurse practitioner have no formal training in those illnesses.
The patients are prescribed expensive treatments that come straight out of their pocket because insurance does not pay for the treatments. The treatments are arbitrary, one size fits all. They have no basis or evidence of science. The therapies are ineffective and not been subjected to clinical trials and are potentially unsafe.

Dr. Buttar did not see the patient. She was in a different state, after all. But, her mother drove her to North Carolina to see Dr. Buttar and he still didn’t see her?

Without seeing her, he took her off her other medications and gave her his own–and she became worse.

Here are sections from the actual testimony.

Q And your daughter never made a personal visit to Dr. Buttar’s office prior to these treatments?
A That’s right.
Q When you had these telephone consultations with Dr. Buttar’s office, did ?- was it with Dr. Buttar?
A No.
Q Who was it with?
A With Jane Garcia.
Q And who is Ms. Garcia?
A I understand her to be his nurse.

Dr. Buttar was not in contact with the family. His nurse practitioner was handling the case. Remotely. Without seeing the patient.

Q Okay. Did Ms. Garcia ever make any recommendations about what to do with your child’s medication she was presently on?
A Yes. She insisted that we remove my daughter from the medication or they would not pursue the treatment.
Q What medication was your daughter on?
A Lexapro for anxiety ?-
Q And ?- and how long did ?- how long had your daughter been on Lexapro?
A About a period of a year.
Q And who prescribed that Lexapro?
A Her local pediatrician.
Q Did Dr. Buttar’s office consult with your local pediatrician when they recommended that she be taken off Lexapro?
A No, they did not.
Q And at some point what happened to your daughter after she started ?- after you started self-administering this chelation cream?
A Initially, it was uneventful, but she began to deteriorate, regress is how it’s referred to, and the regression was extremely significant. We were unable to even get her to come out of the home when she had previously been very social and happy. She wouldn’t wear clothes. She was no longer sleeping through the night. She wasn’t eating properly and she was extremely restless.
Q Okay. And did you consult Dr. Buttar’s office about these issues?
A Absolutely.
Q And what was the response?
A That we just needed to continue because this was to be expected, that she was moving metal and that we just needed to keep doing what we were doing.
Q Okay. And ?- and did you continue to do that?
A Yes.
Q And at some ?- and how did your daughter respond even after you continued the ?- the treatments?
A She just continued to get worse.
Q And at some point did ?- what did you do after that?
A Well, we had made an appointment to come to the office in person and we had hoped at that point, with an in-person physical examination by the doctor, we would get some remedy and advice for the significant amount of deterioration we were experiencing.

Dr. Buttar’s office pulled the young girl off of her anxiety medication. They had the family apply a trans-dermal chelation cream. The girl started to “deteriorate”

Q And I’ll read to you a note and ask you to comment. It says: Discussed plan with Jane, concur on issue regarding Lexapro, reassess patient that worsening is to be expected due to Herxheimer’s response and due to mobilization. Due to age consider IV challenge for best metal yield.
Is that when you talked ?- is that when you and Dr. Buttar’s office began talking about ?-
A I’m sorry, can you repeat that? My phone calling interrupted.
Q I’m sorry. It says: Discussed plan with Jane, concur on issue regarding Lexapro. Is that when you had a conversation about taking your child off Lexapro?
A Yes, but I hope that’s not referring to me concurring.
Q Okay. And above that there’s a typed note that says: Plan to wean off Lexapro, discussed with Dr. Buttar.
But is ?- were you having conversations with Ms. Garcia to take your child off Lexapro and then start this chelation therapy for your child’s autism?

Dr. Buttar suggested a “challenge” chelation test. Here is what the Americal College of Medical Toxicologists has to say about “challenge” testing:

It is, therefore, the position of the American College of Medical Toxicology that post-challenge urinary metal testing has not been scientifically validated, has no demonstrated benefit, and may be harmful when applied in the assessment and treatment of patients in whom there is concern for metal poisoning.

I guess I am curious as to why Dr. Buttar thought an IV chelation was needed for the challenge. If his trans-dermal cream chelates, shouldn’t that be sufficient?

Q I’m sorry. It says: Discussed plan with Jane, concur on issue regarding Lexapro. Is that when you had a conversation about taking your child off Lexapro?
A Yes, but I hope that’s not referring to me concurring.
Q Okay. And above that there’s a typed note that says: Plan to wean off Lexapro, discussed with Dr. Buttar.
