As More People Crowdfund Medical Bills, Beware of Dubious Campaigns
Individuals seeking funding for experimental therapies may enroll in legitimate clinical trials -- or fall prey to snake oil.
Nearly a decade ago, Jamie Anderson hit his highest weight ever: 618 pounds. Depression drove him to eat and eat. He tried all kinds of diets, losing and regaining weight again and again. Then, four years ago, a friend nudged him to join a gym, and with a trainer's guidance, he embarked on a life-altering path.
Ethicists become particularly alarmed when medical crowdfunding appeals are for scientifically unfounded and potentially harmful interventions.
"The big catalyst for all of this is, I was diagnosed as a diabetic," says Anderson, a 46-year-old sales associate in the auto care department at Walmart. Within three years, he was down to 276 pounds but left with excess skin, which sagged from his belly to his mid-thighs.
Plastic surgery would cost $4,000 more than the sum his health insurance approved. That's when Anderson, who lives in Cabot, Arkansas, a suburb outside of Little Rock, turned to online crowdfunding to raise money. In a few months last year, current and former co-workers and friends of friends came up with that amount, covering the remaining expenses for the tummy tuck and overnight hospital stay.
The crowdfunding site that he used, CoFund Health, aimed to give his donors some peace of mind about where their money was going. Unlike GoFundMe and other platforms that don't restrict how donations are spent, Anderson's funds were loaded on a debit card that only worked at health care providers, so the donors "were assured that it was for medical bills only," he says.
CoFund Health was started in January 2019 in response to concerns about the legitimacy of many medical crowdfunding campaigns. As crowdfunding for health-related expenses has gained more traction on social media sites, with countless campaigns seeking to subsidize the high costs of care, it has given rise to some questionable transactions and legitimate ethical concerns.
Common examples of alleged fraud have involved misusing the donations for nonmedical purposes, feigning or embellishing the story of one's own unfortunate plight or that of another person, or impersonating someone else with an illness. Ethicists become particularly alarmed when medical crowdfunding appeals are for scientifically unfounded and potentially harmful interventions.
About 20 percent of American adults reported giving to a crowdfunding campaign for medical bills or treatments, according to a survey by AmeriSpeak Spotlight on Health from NORC, formerly called the National Opinion Research Center, a non-partisan research institution at the University of Chicago. The self-funded poll, conducted in November 2019, included 1,020 interviews with a representative sample of U.S. households. Researchers cited a 2019 City University of New York-Harvard study, which noted that medical bills are the most common basis for declaring personal bankruptcy.
Some experts contend that crowdfunding platforms should serve as gatekeepers in prohibiting campaigns for unproven treatments. Facing a dire diagnosis, individuals may go out on a limb to try anything and everything to prolong and improve the quality of their lives.
They may enroll in well-designed clinical trials, or they could fall prey "to snake oil being sold by people out there just making a buck," says Jeremy Snyder, a health sciences professor at Simon Fraser University in British Columbia, Canada, and the lead author of a December 2019 article in The Hastings Report about crowdfunding for dubious treatments.
For instance, crowdfunding campaigns have sought donations for homeopathic healing for cancer, unapproved stem cell therapy for central nervous system injury, and extended antibiotic use for chronic Lyme disease, according to an October 2018 report in the Journal of the American Medical Association.
Ford Vox, the lead author and an Atlanta-based physician specializing in brain injury, maintains that a repository should exist to monitor the outcomes of experimental treatments. "At the very least, there ought to be some tracking of what happens to the people the funds are being raised for," he says. "It would be great for an independent organization to do so."
"Even if it appears like a good cause, consumers should still do some research before donating to a crowdfunding campaign."
The Federal Trade Commission, the national consumer watchdog, cautions online that "it might be impossible for you to know if the cause is real and if the money actually gets to the intended recipient." Another caveat: Donors can't deduct contributions to individuals on tax returns.
"Even if it appears like a good cause, consumers should still do some research before donating to a crowdfunding campaign," says Malini Mithal, associate director of financial practices at the FTC. "Don't assume all medical treatments are tested and safe."
Before making any donation, it would be wise to check whether a crowdfunding site offers some sort of guarantee if a campaign ends up being fraudulent, says Kristin Judge, chief executive and founder of the Cybercrime Support Network, a Michigan-based nonprofit that serves victims before, during, and after an incident. They should know how the campaign organizer is related to the intended recipient and note whether any direct family members and friends have given funds and left supportive comments.
Donating to vetted charities offers more assurance than crowdfunding that the money will be channeled toward helping someone in need, says Daniel Billingsley, vice president of external affairs for the Oklahoma Center of Nonprofits. "Otherwise, you could be putting money into all sorts of scams." There is "zero accountability" for the crowdfunding site or the recipient to provide proof that the dollars were indeed funneled into health-related expenses.
Even if donors may have limited recourse against scammers, the "platforms have an ethical obligation to protect the people using their site from fraud," says Bryanna Moore, a postdoctoral fellow at Baylor College of Medicine's Center for Medical Ethics and Health Policy. "It's easy to take advantage of people who want to be charitable."
There are "different layers of deception" on a broad spectrum of fraud, ranging from "outright lying for a self-serving reason" to publicizing an imaginary illness to collect money genuinely needed for basic living expenses. With medical campaigns being a top category among crowdfunding appeals, it's "a lot of money that's exchanging hands," Moore says.
The advent of crowdfunding "reveals and, in some ways, reinforces a health care system that is totally broken," says Jessica Pierce, a faculty affiliate in the Center for Bioethics and Humanities at the University of Colorado Anschutz Medical Campus in Denver. "The fact that people have to scrounge for money to get life-saving treatment is unethical."
Crowdfunding also highlights socioeconomic and racial disparities by giving an unfair advantage to those who are social-media savvy and capable of crafting a compelling narrative that attracts donors. Privacy issues enter into the picture as well, because telling that narrative entails revealing personal details, Pierce says, particularly when it comes to children, "who may not be able to consent at a really informed level."
CoFund Health, the crowdfunding site on which Anderson raised the money for his plastic surgery, offers to help people write their campaigns and copy edit for proper language, says Matthew Martin, co-founder and chief executive officer. Like other crowdfunding sites, it retains a few percent of the donations for each campaign. Martin is the husband of Anderson's acquaintance from high school.
So far, the site, which is based in Raleigh, North Carolina, has hosted about 600 crowdfunding campaigns, some completed and some still in progress. Campaigns have raised as little as $300 to cover immediate dental expenses and as much as $12,000 for cancer treatments, Martin says, but most have set a goal between $5,000 and $10,000.
Whether or not someone's campaign is based on fact or fiction remains for prospective donors to decide.
The services could be cosmetic—for example, a breast enhancement or reduction, laser procedures for the eyes or skin, and chiropractic care. A number of campaigns have sought funding for transgender surgeries, which many insurers consider optional, he says.
In July 2019, a second site was hatched out of pet owners' requests for assistance with their dogs' and cats' medical expenses. Money raised on CoFund My Pet can only be used at veterinary clinics. Martin says the debit card would be declined at other merchants, just as its CoFund Health counterpart for humans will be rejected at places other than health care facilities, dental and vision providers, and pharmacies.
Whether or not someone's campaign is based on fact or fiction remains for prospective donors to decide. If a donor were to regret a transaction, he says the site would reach out to the campaign's owner but ultimately couldn't force a refund, Martin explains, because "it's hard to chase down fraud without having access to people's health records."
In some crowdfunding campaigns, the individual needs some or all the donated resources to pay for travel and lodging at faraway destinations to receive care, says Snyder, the health sciences professor and crowdfunding report author. He suggests people only give to recipients they know personally.
"That may change the calculus a little bit," tipping the decision in favor of donating, he says. As long as the treatment isn't harmful, the funds are a small gesture of support. "There's some value in that for preserving hope or just showing them that you care."
Regenerative medicine has come a long way, baby
After a cloned baby sheep, what started as one of the most controversial areas in medicine is now promising to transform it.
The field of regenerative medicine had a shaky start. In 2002, when news spread about the first cloned animal, Dolly the sheep, a raucous debate ensued. Scary headlines and organized opposition groups put pressure on government leaders, who responded by tightening restrictions on this type of research.
Fast forward to today, and regenerative medicine, which focuses on making unhealthy tissues and organs healthy again, is rewriting the code to healing many disorders, though it’s still young enough to be considered nascent. What started as one of the most controversial areas in medicine is now promising to transform it.
Progress in the lab has addressed previous concerns. Back in the early 2000s, some of the most fervent controversy centered around somatic cell nuclear transfer (SCNT), the process used by scientists to produce Dolly. There was fear that this technique could be used in humans, with possibly adverse effects, considering the many medical problems of the animals who had been cloned.
But today, scientists have discovered better approaches with fewer risks. Pioneers in the field are embracing new possibilities for cellular reprogramming, 3D organ printing, AI collaboration, and even growing organs in space. It could bring a new era of personalized medicine for longer, healthier lives - while potentially sparking new controversies.
Engineering tissues from amniotic fluids
Work in regenerative medicine seeks to reverse damage to organs and tissues by culling, modifying and replacing cells in the human body. Scientists in this field reach deep into the mechanisms of diseases and the breakdowns of cells, the little workhorses that perform all life-giving processes. If cells can’t do their jobs, they take whole organs and systems down with them. Regenerative medicine seeks to harness the power of healthy cells derived from stem cells to do the work that can literally restore patients to a state of health—by giving them healthy, functioning tissues and organs.
Modern-day regenerative medicine takes its origin from the 1998 isolation of human embryonic stem cells, first achieved by John Gearhart at Johns Hopkins University. Gearhart isolated the pluripotent cells that can differentiate into virtually every kind of cell in the human body. There was a raging controversy about the use of these cells in research because at that time they came exclusively from early-stage embryos or fetal tissue.
Back then, the highly controversial SCNT cells were the only way to produce genetically matched stem cells to treat patients. Since then, the picture has changed radically because other sources of highly versatile stem cells have been developed. Today, scientists can derive stem cells from amniotic fluid or reprogram patients’ skin cells back to an immature state, so they can differentiate into whatever types of cells the patient needs.
In the context of medical history, the field of regenerative medicine is progressing at a dizzying speed. But for those living with aggressive or chronic illnesses, it can seem that the wheels of medical progress grind slowly.
The ethical debate has been dialed back and, in the last few decades, the field has produced important innovations, spurring the development of whole new FDA processes and categories, says Anthony Atala, a bioengineer and director of the Wake Forest Institute for Regenerative Medicine. Atala and a large team of researchers have pioneered many of the first applications of 3D printed tissues and organs using cells developed from patients or those obtained from amniotic fluid or placentas.
His lab, considered to be the largest devoted to translational regenerative medicine, is currently working with 40 different engineered human tissues. Sixteen of them have been transplanted into patients. That includes skin, bladders, urethras, muscles, kidneys and vaginal organs, to name just a few.
These achievements are made possible by converging disciplines and technologies, such as cell therapies, bioengineering, gene editing, nanotechnology and 3D printing, to create living tissues and organs for human transplants. Atala is currently overseeing clinical trials to test the safety of tissues and organs engineered in the Wake Forest lab, a significant step toward FDA approval.
In the context of medical history, the field of regenerative medicine is progressing at a dizzying speed. But for those living with aggressive or chronic illnesses, it can seem that the wheels of medical progress grind slowly.
“It’s never fast enough,” Atala says. “We want to get new treatments into the clinic faster, but the reality is that you have to dot all your i’s and cross all your t’s—and rightly so, for the sake of patient safety. People want predictions, but you can never predict how much work it will take to go from conceptualization to utilization.”
As a surgeon, he also treats patients and is able to follow transplant recipients. “At the end of the day, the goal is to get these technologies into patients, and working with the patients is a very rewarding experience,” he says. Will the 3D printed organs ever outrun the shortage of donated organs? “That’s the hope,” Atala says, “but this technology won’t eliminate the need for them in our lifetime.”
New methods are out of this world
Jeanne Loring, another pioneer in the field and director of the Center for Regenerative Medicine at Scripps Research Institute in San Diego, says that investment in regenerative medicine is not only paying off, but is leading to truly personalized medicine, one of the holy grails of modern science.
This is because a patient’s own skin cells can be reprogrammed to become replacements for various malfunctioning cells causing incurable diseases, such as diabetes, heart disease, macular degeneration and Parkinson’s. If the cells are obtained from a source other than the patient, they can be rejected by the immune system. This means that patients need lifelong immunosuppression, which isn’t ideal. “With Covid,” says Loring, “I became acutely aware of the dangers of immunosuppression.” Using the patient’s own cells eliminates that problem.
Microgravity conditions make it easier for the cells to form three-dimensional structures, which could more easily lead to the growing of whole organs. In fact, Loring's own cells have been sent to the ISS for study.
Loring has a special interest in neurons, or brain cells that can be developed by manipulating cells found in the skin. She is looking to eventually treat Parkinson’s disease using them. The manipulated cells produce dopamine, the critical hormone or neurotransmitter lacking in the brains of patients. A company she founded plans to start a Phase I clinical trial using cell therapies for Parkinson’s soon, she says.
This is the culmination of many years of basic research on her part, some of it on her own cells. In 2007, Loring had her own cells reprogrammed, so there’s a cell line that carries her DNA. “They’re just like embryonic stem cells, but personal,” she said.
Loring has another special interest—sending immature cells into space to be studied at the International Space Station. There, microgravity conditions make it easier for the cells to form three-dimensional structures, which could more easily lead to the growing of whole organs. In fact, her own cells have been sent to the ISS for study. “My colleagues and I have completed four missions at the space station,” she says. “The last cells came down last August. They were my own cells reprogrammed into pluripotent cells in 2009. No one else can say that,” she adds.
Future controversies and tipping points
Although the original SCNT debate has calmed down, more controversies may arise, Loring thinks.
One of them could concern growing synthetic embryos. The embryos are ultimately derived from embryonic stem cells, and it’s not clear to what stage these embryos can or will be grown in an artificial uterus—another recent invention. The science, so far done only in animals, is still new and has not been widely publicized but, eventually, “People will notice the production of synthetic embryos and growing them in an artificial uterus,” Loring says. It’s likely to incite many of the same reactions as the use of embryonic stem cells.
Bernard Siegel, the founder and director of the Regenerative Medicine Foundation and executive director of the newly formed Healthspan Action Coalition (HSAC), believes that stem cell science is rapidly approaching tipping point and changing all of medical science. (For disclosure, I do consulting work for HSAC). Siegel says that regenerative medicine has become a new pillar of medicine that has recently been fast-tracked by new technology.
Artificial intelligence is speeding up discoveries and the convergence of key disciplines, as demonstrated in Atala’s lab, which is creating complex new medical products that replace the body’s natural parts. Just as importantly, those parts are genetically matched and pose no risk of rejection.
These new technologies must be regulated, which can be a challenge, Siegel notes. “Cell therapies represent a challenge to the existing regulatory structure, including payment, reimbursement and infrastructure issues that 20 years ago, didn’t exist.” Now the FDA and other agencies are faced with this revolution, and they’re just beginning to adapt.
Siegel cited the 2021 FDA Modernization Act as a major step. The Act allows drug developers to use alternatives to animal testing in investigating the safety and efficacy of new compounds, loosening the agency’s requirement for extensive animal testing before a new drug can move into clinical trials. The Act is a recognition of the profound effect that cultured human cells are having on research. Being able to test drugs using actual human cells promises to be far safer and more accurate in predicting how they will act in the human body, and could accelerate drug development.
Siegel, a longtime veteran and founding father of several health advocacy organizations, believes this work helped bring cell therapies to people sooner rather than later. His new focus, through the HSAC, is to leverage regenerative medicine into extending not just the lifespan but the worldwide human healthspan, the period of life lived with health and vigor. “When you look at the HSAC as a tree,” asks Siegel, “what are the roots of that tree? Stem cell science and the huge ecosystem it has created.” The study of human aging is another root to the tree that has potential to lengthen healthspans.
The revolutionary science underlying the extension of the healthspan needs to be available to the whole world, Siegel says. “We need to take all these roots and come up with a way to improve the life of all mankind,” he says. “Everyone should be able to take advantage of this promising new world.”
Joy Milne's unusual sense of smell led Dr. Tilo Kunath, a neurobiologist at the Centre for Regenerative Medicine at the University of Edinburgh, and a host of other scientists, to develop a new diagnostic test for Parkinson's.
Forty years ago, Joy Milne, a nurse from Perth, Scotland, noticed a musky odor coming from her husband, Les. At first, Milne thought the smell was a result of bad hygiene and badgered her husband to take longer showers. But when the smell persisted, Milne learned to live with it, not wanting to hurt her husband's feelings.
Twelve years after she first noticed the "woodsy" smell, Les was diagnosed at the age of 44 with Parkinson's Disease, a neurodegenerative condition characterized by lack of dopamine production and loss of movement. Parkinson's Disease currently affects more than 10 million people worldwide.
Milne spent the next several years believing the strange smell was exclusive to her husband. But to her surprise, at a local support group meeting in 2012, she caught the familiar scent once again, hanging over the group like a cloud. Stunned, Milne started to wonder if the smell was the result of Parkinson's Disease itself.
Milne's discovery led her to Dr. Tilo Kunath, a neurobiologist at the Centre for Regenerative Medicine at the University of Edinburgh. Together, Milne, Kunath, and a host of other scientists would use Milne's unusual sense of smell to develop a new diagnostic test, now in development and poised to revolutionize the treatment of Parkinson's Disease.
"Joy was in the audience during a talk I was giving on my work, which has to do with Parkinson's and stem cell biology," Kunath says. "During the patient engagement portion of the talk, she asked me if Parkinson's had a smell to it." Confused, Kunath said he had never heard of this – but for months after his talk he continued to turn the question over in his mind.
Kunath knew from his research that the skin's microbiome changes during different disease processes, releasing metabolites that can give off odors. In the medical literature, diseases like melanoma and Type 2 diabetes have been known to carry a specific scent – but no such connection had been made with Parkinson's. If people could smell Parkinson's, he thought, then it stood to reason that those metabolites could be isolated, identified, and used to potentially diagnose Parkinson's by their presence alone.
First, Kunath and his colleagues decided to test Milne's sense of smell. "I got in touch with Joy again and we designed a protocol to test her sense of smell without her having to be around patients," says Kunath, which could have affected the validity of the test. In his spare time, Kunath collected t-shirt samples from people diagnosed with Parkinson's and from others without the diagnosis and gave them to Milne to smell. In 100 percent of the samples, Milne was able to detect whether a person had Parkinson's based on smell alone. Amazingly, Milne was even able to detect the "Parkinson's scent" in a shirt from the control group – someone who did not have a Parkinson's diagnosis, but would go on to be diagnosed nine months later.
From the initial study, the team discovered that Parkinson's did have a smell, that Milne – inexplicably – could detect it, and that she could detect it long before diagnosis like she had with her husband, Les. But the experiments revealed other things that the team hadn't been expecting.
"One surprising thing we learned from that experiment was that the odor was always located in the back of the shirt – never in the armpit, where we expected the smell to be," Kunath says. "I had a chance meeting with a dermatologist and he said the smell was due to the patient's sebum, which are greasy secretions that are really dense on your upper back. We have sweat glands, instead of sebum, in our armpits." Patients with Parkinson's are also known to have increased sebum production.
With the knowledge that a patient's sebum was the source of the unusual smell, researchers could go on to investigate exactly what metabolites were in the sebum and in what amounts. Kunath, along with his associate, Dr. Perdita Barran, collected and analyzed sebum samples from 64 participants across the United Kingdom. Once the samples were collected, Barran and others analyzed it using a method called gas chromatography mass spectrometry, or GS-MC, which separated, weighed and helped identify the individual compounds present in each sebum sample.
Barran's team can now correctly identify Parkinson's in nine out of 10 patients – a much quicker and more accurate way to diagnose than what clinicians do now.
"The compounds we've identified in the sebum are not unique to people with Parkinson's, but they are differently expressed," says Barran, a professor of mass spectrometry at the University of Manchester. "So this test we're developing now is not a black-and-white, do-you-have-something kind of test, but rather how much of these compounds do you have compared to other people and other compounds." The team identified over a dozen compounds that were present in the sebum of Parkinson's patients in much larger amounts than the control group.
Using only the GC-MS and a sebum swab test, Barran's team can now correctly identify Parkinson's in nine out of 10 patients – a much quicker and more accurate way to diagnose than what clinicians do now.
"At the moment, a clinical diagnosis is based on the patient's physical symptoms," Barran says, and determining whether a patient has Parkinson's is often a long and drawn-out process of elimination. "Doctors might say that a group of symptoms looks like Parkinson's, but there are other reasons people might have those symptoms, and it might take another year before they're certain," Barran says. "Some of those symptoms are just signs of aging, and other symptoms like tremor are present in recovering alcoholics or people with other kinds of dementia." People under the age of 40 with Parkinson's symptoms, who present with stiff arms, are often misdiagnosed with carpal tunnel syndrome, she adds.
Additionally, by the time physical symptoms are present, Parkinson's patients have already lost a substantial amount of dopamine receptors – about sixty percent -- in the brain's basal ganglia. Getting a diagnosis before physical symptoms appear would mean earlier interventions that could prevent dopamine loss and preserve regular movement, Barran says.
"Early diagnosis is good if it means there's a chance of early intervention," says Barran. "It stops the process of dopamine loss, which means that motor symptoms potentially will not happen, or the onset of symptoms will be substantially delayed." Barran's team is in the processing of streamlining the sebum test so that definitive results will be ready in just two minutes.
"What we're doing right now will be a very inexpensive test, a rapid-screen test, and that will encourage people to self-sample and test at home," says Barran. In addition to diagnosing Parkinson's, she says, this test could also be potentially useful to determine if medications were at a therapeutic dose in people who have the disease, since the odor is strongest in people whose symptoms are least controlled by medication.
"When symptoms are under control, the odor is lower," Barran says. "Potentially this would allow patients and clinicians to see whether their symptoms are being managed properly with medication, or perhaps if they're being overmedicated." Hypothetically, patients could also use the test to determine if interventions like diet and exercise are effective at keeping Parkinson's controlled.
"We hope within the next two to five years we will have a test available."
Barran is now running another clinical trial – one that determines whether they can diagnose at an earlier stage and whether they can identify a difference in sebum samples between different forms of Parkinson's or diseases that have Parkinson's-like symptoms, such as Lewy Body Dementia.
"Within the next one to two years, we hope to be running a trial in the Manchester area for those people who do not have motor symptoms but are at risk for developing dementia due to symptoms like loss of smell and sleep difficulty," Barran had said in 2019. "If we can establish that, we can roll out a test that determines if you have Parkinson's or not with those first pre-motor symptoms, and then at what stage. We hope within the next two to five years we will have a test available."
In a 2022 study, published in the American Chemical Society, researchers used mass spectrometry to analyze sebum from skin swabs for the presence of the specific molecules. They found that some specific molecules are present only in people who have Parkinson’s. Now they hope that the same method can be used in regular diagnostic labs. The test, many years in the making, is inching its way to the clinic.
"We would likely first give this test to people who are at risk due to a genetic predisposition, or who are at risk based on prodomal symptoms, like people who suffer from a REM sleep disorder who have a 50 to 70 percent chance of developing Parkinson's within a ten year period," Barran says. "Those would be people who would benefit from early therapeutic intervention. For the normal population, it isn't beneficial at the moment to know until we have therapeutic interventions that can be useful."
Milne's husband, Les, passed away from complications of Parkinson's Disease in 2015. But thanks to him and the dedication of his wife, Joy, science may have found a way to someday prolong the lives of others with this devastating disease. Sometimes she can smell people who have Parkinson’s while in the supermarket or walking down the street but has been told by medical ethicists she cannot tell them, Milne said in an interview with the Guardian. But once the test becomes available in the clinics, it will do the job for her.
