TikTok: A Vector for Dangerous Misinformation

 In The Politics of Autism, I examine the role of social media in the development of the issue

Dexter McMillan at CBC Marketplace:
Marketplace journalists analyzed 100 videos discussing cancer treatments and another 100 for autism therapies. We found that at least 80 per cent of the remedies in the videos — totalling more than 75 million views — weren’t supported by scientific evidence.
...
Marketplace searched TikTok for cancer videos using the search terms "cancer cure" and "cancer treatment," and for autism videos using the terms "autism cure," "autism treatment" and "autism." Starting with the most viewed, we chose 100 each that featured a treatment or cure.
...
Marketplace journalists also found treatments our experts identified as dangerous among the 100 videos on autism.

One video with 760,000 views claimed that chelation therapy — typically used to treat heavy metal poisoning — can improve communication and behaviour in children with autism.

The medical procedure involves using an IV to administer chemicals that bind heavy metals in the body and eliminate them. The video claimed that removing these heavy metals improves autism symptoms.

In addition to this claim being unsupported by science, the treatment can be dangerous, said Dr. Melanie Penner, a pediatrician and autism researcher in Toronto.

...

Stem cell therapies for autism were featured in at least 14 videos reviewed by Marketplace, racking up 3.2 million views altogether. It involves infusing stem cells into the body using an IV.
...
Penner said the research doesn't support that. Meanwhile, these treatments can have serious complications.

The Cruelty of the Antivaxxers

In The Politics of Autism, I analyze the discredited notion that vaccines cause autism. This bogus idea can hurt people by allowing diseases to spread  And among those diseases could be COVID-19.

Antivaxxers are sometimes violent, often abusive, and always wrongA leading anti-vaxxer is presidential candidate Robert F. Kennedy, Jr.  He has repeatedly compared vaccine mandates to the Holocaust.  Rolling Stone and Salon retracted an RFK article linking vaccines to autism.


What many do not understand is that for a significant number parents of children with autism, anti-vaccination beliefs carry the pernicious and agonizing false hope of a cure. Blaming vaccines for a child’s autism is cruel and misleading, and preys on parents and families at their most vulnerable. Currently, there is no medical “cure” for the core symptoms of autism. Children with autism typically receive behavior and educational interventions for skill development.

...

Behind the vaccine-autism myth is a multimillion-dollar industry dedicated to reversing autism. The autism recovery industry is populated by a number of entrepreneurs and businesses, but most common are specialized laboratories, compounding pharmacies and purveyors of experimental treatments.

The majority of these experimental treatments lack scientific support and, in some cases, are incredibly harmful as well as wildly expensive. During my study, I observed parents of children with autism experimenting with parasite therapy to address inflammation, hormone therapy to delay puberty, and even stem cell therapies in Mexico and India.

...

We cannot afford to think of RFK Jr.’s campaign as just a possible election spoiler. Kennedy and Shanahan are sowers of misinformation and the lasting damage they may have on vaccine trust should not be underestimated. As a researcher and an educator, it is my hope that enhanced public scrutiny will help reveal how this movement is based on debunked research, lies and delusions.

Duke and Stem Cells

In The Politics of Autism, I write:

The conventional wisdom is that any kind of treatment is likely to be less effective as the child gets older, so parents of autistic children usually believe that they are working against the clock. They will not be satisfied with the ambiguities surrounding ABA, nor will they want to wait for some future research finding that might slightly increase its effectiveness. They want results now. Because there are no scientifically-validated drugs for the core symptoms of autism, they look outside the boundaries of mainstream medicine and FDA approval. Studies have found that anywhere from 28 to 54 percent of autistic children receive “complementary and alternative medicine” (CAM), and these numbers probably understate CAM usage.
For several years, parents of autistic children have paid between $10,000 and $15,000 to have their children undergo unproven stem cell and cord blood treatments at Duke University, through what’s called an expanded access program, or EAP. That practice has attracted criticism from observers and ethicists in the stem cell field, who have asked why Duke was charging money for a service when its own clinical trials have not been very promising. In recent months, Duke has sent letters informing parents that this program is no longer available to autistic children—raising new questions about what those parents, who’d been led to believe the treatment might be a panacea for their kids, will do instead.

One of the more urgent questions is whether parents who can’t access the treatment though Duke will instead go to a for-profit partner with ties to the school. That would be Cryo-Cell International, which previously announced that it had entered into a licensing agreement with Duke allowing it to offer the same stem cell infusions in private, for-profit clinics the company has said it plans to begin opening this year. (Duke previously told Motherboard that “the licensing agreement does not grant Cryo-Cell the use of Duke’s EAP for the treatment of patients at Cryo-Cell, but will allow Cryo-Cell to develop its own cell therapy program.”)

Autism Hype

In The Politics of Autism, I discuss various ideas about what causes the condition and how to treat it.  I also write:  "If the science were not confusing enough, its coverage in the mass media has added another layer of murk.  News reports hype tentative findings and weak correlations as “breakthroughs” in the quest for autism answers. 

In the worst scenarios, families inspired by media coverage may pursue treatments that are both ineffective and unsafe. This has been the case with MDMA, or 3,4-methyldioxymethamphetamine, otherwise known as ecstasy, to treat social anxiety in autistic adults. Much media coverage of this experimental treatment failed to report that the drug is neurotoxic in animal models and humans, and that a “safe” dose has not been established. As a result, the public received complete misinformation via mainstream media outlets. The false hope of MDMA might have led some in the autism community to pursue an illegal—and, more importantly, potentially lethal—intervention.
...
. In another case, the headline “Stem Cells Offer Hope for Autism” might have encouraged families to travel to international sites with unregulated medical practices to obtain this therapy, which is still unproven. Conversely, the media is largely missing the mark on the potential of medical marijuana, confusing different cannabinoids and mixing up indications in their headlines. This type of misinformation will only serve to stifle badly needed research into phytocannabinoids in marijuana that do, in fact, show promise for treating epilepsy, which commonly co-occurs in children with autism.

FTC Cracks Down on Quack Stem Cell Treatment

In The Politics of Autism, I write:
The conventional wisdom is that any kind of treatment is likely to be less effective as the child gets older, so parents of autistic children usually believe that they are working against the clock. They will not be satisfied with the ambiguities surrounding ABA, nor will they want to wait for some future research finding that might slightly increase its effectiveness. They want results now.

Studies have found that anywhere from 28 to 54 percent of autistic children receive “complementary and alternative medicine” (CAM), and these numbers probably understate CAM usage.
A release from FTC:
A California-based physician and the two companies he controls have settled charges of deceptively advertising that “amniotic stem cell therapy” can treat serious diseases, including Parkinson’s disease, autism, macular degeneration, cerebral palsy, multiple sclerosis, and heart attacks.
The settlement prohibits the defendants from making these and other health claims in the future unless the claims are true and supported by competent and reliable scientific evidence. The settlement also imposes a partially suspended $3.31 million judgment and requires the defendants to notify current and former patients about the order within 30 days.
...
According to the Commission’s complaint, Dr. Bryn Jarald Henderson, D.O. and the two companies he owns and operates, Regenerative Medical Group and Telehealth Medical Group, earned at least $3.31 million offering stem cell therapy between 2014 and 2017. Initial stem cell therapy injections ranged from $9,500 to $15,000, with patients encouraged to undergo multiple treatments. Follow-up “booster” treatments cost between $5,000 and $8,000 each.
...
Advertising on the website stemcell.life, the defendants even claimed that the therapy could restore the vision of blind patients, citing the case of a “101 year old Lady once blind for 7 years” who, thanks to stem cell therapy, could see again. The website’s homepage boasted that the therapy could “reverse autism symptoms.”

The proposed order settling the FTC’s charges prohibits the defendants from misrepresenting that any product or service: 1) cures, mitigates, or treats any disease or health condition, including Parkinson’s disease, autism, multiple sclerosis, cerebral palsy, traumatic brain injury, heart disease, macular degeneration, chronic kidney disease, osteoarthritis, and stroke; or 2) is comparable, or better than, conventional medical treatments in treating any health condition, unless such claims are true and can be supported by competent and reliable scientific evidence.

Stem Cell Research in the Media

 In The Politics of Autism, I write:  "If the science were not confusing enough, its coverage in the mass media has added another layer of murk.  News reports hype tentative findings and weak correlations as “breakthroughs” in the quest for autism answers."

At Stem Cell Reviews and Reports, Kimberly Sharpe, Nina Di Pietro and Judy Illes have an article titled "In the Know and in the News: How Science and the Media Communicate About Stem Cells, Autism and Cerebral Palsy."  The abstract:
Stem cell research has generated considerable attention for its potential to remediate many disorders of the central nervous system including neurodevelopmental disorders such as autism spectrum disorder (ASD) and cerebral palsy (CP) that place a high burden on individual children, families and society. Here we characterized messaging about the use of stem cells for ASD and CP in news media articles and concurrent dissemination of discoveries through conventional science discourse. We searched LexisNexis and Canadian Newsstand for news articles from the US, UK, Canada and Australia in the period between 2000 and 2014, and PubMed for peer reviewed articles for the same 10 years. Using in-depth content analysis methods, we found less cautionary messaging about stem cells for ASD and CP in the resulting sample of 73 media articles than in the sample of 87 science papers, and a privileging of benefits over risk. News media also present stem cells as ready for clinical application to treat these neurodevelopmental disorders, even while the science literature calls for further research. Investigative news reports that explicitly quote researchers, however, provide the most accurate information to actual science news. The hope, hype, and promise of stem cell interventions for neurodevelopmental disorders, combined with the extreme vulnerability of these children and their families, creates a perfect storm in which journalists and stem cell scientists must commit to a continued, if not even more robust, partnership to promote balanced and accurate messaging.

Stem Cell Trial

From SFARI:
A team at Duke University in Durham, North Carolina, is set to launch a $40 million clinical trial to explore stem cells from umbilical cord blood as a treatment for autism. But experts caution that the trial is premature.
A $15 million grant from the Marcus Foundation, a philanthropic funding organization based in Atlanta, will bankroll the first two years of the five-year trial, which also plans to test stem cell therapy for stroke and cerebral palsy. The autism arm of the trial aims to enroll 390 children and adults.
Joanne Kurtzberg, the trial’s lead investigator, has extensive experience studying the effectiveness of cord blood transplants for treating various disorders, such as leukemia and sickle cell anemia1. Most recently, she showed that cord blood transplants can improve the odds of survival for babies deprived of oxygen at birth. A randomized trial of the approach for this condition is underway2.
“To really sort out if [stem] cells can treat these children, we need to do randomized, controlled trials that are well designed and well controlled, and that’s what we intend to do,” says Kurtzberg, professor of pediatrics and pathology at Duke. “We firmly believe we should be moving ahead in the clinic.”

Early animal studies have shown that stem cells isolated from umbilical cord blood can stimulate cells in the spinal cord to regrow their myelin layers, and in doing so help restore connections with surrounding cells3. Autism is thought to result from impaired connectivity in the brain. Because of this, some groups of children with the disorder may benefit from a stem cell transplant, Kurtzberg says.
But others are skeptical of the approach. Autism is a complex disorder with many possible causes. Also, it’s unclear how stem cells derived from cord blood can improve connections in the brain. Given these important caveats, it’s too soon to conduct a test of this scale and investment, some experts say.
“It’s probably premature to run large trials without evidence that they have a therapeutic effect that [we] understand,” cautions Arnold Kriegstein, director of the Broad Center of Regenerative Medicine and Stem Cell Research at the University of California, San Francisco.

Looking for a Cure

The Staten Island Advance reports on Eileen Phoenix, a local woman with an ASD daughter:
Like a growing number of people today, Ms. Phoenix has taken a total natural healing approach toward treating her child: A gluten-free diet. Supplements. Sensory integration. Auditory integration.

After Kasey seemed to have favorable results with craniosacral therapy, a form of massage, Ms. Phoenix went to school to be trained in this technique. What originally began as an effort to save money turned into a career as an acupuncturist with her own practice, Clear Light Acupuncture, in her home.

The mother also tried experimental treatments, many of which are not approved by the United States and cost thousands of dollars.

“I’ve walked into bars at midnight with a coffee can and her picture to try to raise money for her,” she said, noting other people, such as Ms. [Nicole] McDowell, also have helped her stage fund-raisers to pay for these costly procedures.
According to Ms. McDowell, a principal at You and Me School for Children with Autism in Edison, N.J., many parents of autistic kids turn to experimental treatments, “desperate to find anything that might improve their child in the slightest.”

While the Eltingville resident says she “can understand how these families feel about their children and how they’re willing to do almost anything,” as a BCBA, she counsels them against such therapies. Not only are they expensive, she said, but there also is no empirical evidence proving their effectiveness — though, it seems, Kasey did improve after two particular procedures.

Ms. McDowell explains that at age 4 Kasey had plateaued in identifying colors and only was able to determine the difference between red and blue after going to auditory integration therapy.

The second major advance happened when Ms. McDowell accompanied the family on a trip to the Bahamas, where Kasey, then 8, was injected with embryonic stem cells.

After that, she had a giant leap, from speaking one sentence to about 50, and being able to identify kids at her school, which she couldn’t do before.

While Ms. McDowell said she “cannot say the improvement was a direct result” of these therapies, the records she keeps on Kasey do show the girl had a boost in learning afterward.

“But again,” she stressed, “this is not supported by research at all.”
The Sacramento Bee reports on the mother of one boy with ASD and another with epilepsy. She heard about stem cell therapy in Panama:
At one such facility, the Stem Cell Institute in Panama, stem cells from human umbilical cords collected from donors are used to treat autism.

The website promises: Stem cells are capable of regeneration and differentiation, once injected, they can "follow inflammatory signals from damaged tissues and have multiple ways of repairing those damaged areas."

My calls and emails to the institute went unanswered.

There are many unknowns when it comes to stem cell-based therapy and its potential to treat autism, said Dr. Michael Chez, director of Pediatric Neurology at the Sutter Neuroscience Institute in Sacramento.

Stem cell-based therapy is steeped in mystery for the average person, and they tend to think of it as a cure-all, said Chez, who also is Dylan and Devon Le's physician.

"Everybody has stem cells in their body, and as we age, they may be more and more difficult to access," he said.

Stem cells can't just be inserted into the body and magically evolve into a spare part or the thing you need it to become, he said.

"Many things have to happen first before they become able to change," he said.

...

"A lot of people who are desperate might seek this out in other countries because they're not as regulated as this country is," Chez said.

He anticipates leading a controlled study involving cord blood and autism by the end of the year.

"A controlled study needs to be done looking at patients given essentially a placebo vs. the cord blood, and we are designing such a study," he said. "If anybody were to have done this anywhere, it would add validity to this type of treatment."

In the meantime, parents should be very cautious of offers of autism "cures" that proliferate on the Internet.

"There have always been people trying to offer false hope to people with autism," Chez said. "Unless it's being done in the U.S. or in a medical center in a controlled study or in some type of valid research study, be careful. Going anywhere outside of those environments probably means you're giving your money away without any kind of guaranteed success.

"I understand the desperation, but the Internet is not policed with scientific information."

Autism and Stem Cells

As an earlier post explained, there is legitimate research into stem cells and autism. But it will be many years before this research actually does something for people on the spectrum. Meanwhile, as Time reports some are still trying to make a buck:

Stem cell research is on the tip of everyone's tongue and regularly in the news, but a panel of British health officials warns that a global crop of unlicensed clinics is taking advantage of all the publicity.

Clinics in places as varied as Mexico, Thailand, Germany, Russia and China offer stem cell therapies with high price tags and little clinical evidence to back them up. Because such clinics are not illegal, experts in the emerging field of regenerative medicine are combating the misinformation with a guide to good quality treatment.

If you are thinking about trying stem cell therapy for anything from autism to diabetes to lupus, it might be worth your while to peruse the Task Force on Unproven Stem Cell Treatments' website, part of The International Society for Stem Cell Research.

"I've made some very strong comments which could potentially land me in court, but people still go to these clinics," said Professor Peter Coffey, director of the London Project to Cure Blindness at University College London. There are now several hundred clinics around the world which claim to have turned the potential of stem cells into effective treatments. They lure those suffering from diabetes, multiple sclerosis, heart failure, Parkinson's disease, autism, HIV, eye problems, spinal cord injuries and much else besides.

Several thousand people from around the world so far are estimated to have spent up to £20,000 or more in such places. Yet while stem cells could transform medicine, there is as yet scant actual proof of their efficacy. But still the tourists come.

The fact that scientists believe it is likely to be 15 to 20 years before the continuing worldwide flurry of trials and tests results in reliable treatments has not stopped clinics from offering exactly that already. Strong regulation means there are no such places in the UK or America. But the experts did single out the XCell Centre in Düsseldorf, Germany, and Beike Technology, which runs one in Shenzhen in China.

Stem Cells, Lawyers, and Autism

The San Jose Mercury News reports:

When a child dies of brain disease at Children's Hospital of Orange County, Philip H. Schwartz meets with the parents, explains his research and asks them to donate their child's brain to his quest for a cure.

"These are not easy conversations to have," he said. "There are expectations by parents that if they allow us to do that to their child, it will serve a useful purpose."

But for three years, the cells derived from many of those children's brains have been suspended in limbo, frozen in Thermos bottles. The nonprofit Southern California hospital has shut down the research, intimidated by a patent claim from the Palo Alto biotech company StemCells. The company's co-founder is esteemed Stanford stem cell scientist Dr. Irving Weissman, one of the world's most passionate advocates for giving scientists access to a field entangled by politics, ethics — and now money.

...

"You can create the battle in a culture dish," said Schwartz, saying it could also benefit research into diseases like Alzheimer's and Parkinson's. "Autism — we don't even have a blood test. We don't understand what it is. In metabolic diseases that affect the brain, what is the sequence of events? What kills them?

"These cells can be used to help us get an idea."
