Elite Hospitals Plunge Into Unproven Stem Cell Treatments

The on-line video appears to vow every part an arthritis affected person might need.

The six-minute phase mimics a morning discuss present, utilizing a cultured TV host to interview company round a espresso desk. Dr. Adam Pourcho extols the advantages of stem cells and “regenerative medicine” for therapeutic joints with out surgical procedure. Pourcho, a sports activities medication specialist, says he has used platelet injections to deal with his personal knee ache, in addition to a tendon harm in his elbow. Extending his arm, he says, “It’s completely healed.”

Brendan Hyland, a gymnasium trainer and monitor coach, describes withstanding intense heel ache for 18 months earlier than seeing Pourcho. Four months after the injections, he says, he was pain-free and has since gone on a 40-mile hike.

“I don’t have any pain that stops me from doing anything I want,” Hyland says.

The video’s cheerleading tone mimics the infomercials used to advertise stem cell clinics, a number of of which have not too long ago gotten into sizzling water with federal regulators, mentioned Dr. Paul Knoepfler, a professor of cell biology and human anatomy on the University of California-Davis School of Medicine. But the advertising and marketing video wasn’t filmed by a little-known operator.

It was sponsored by Swedish Medical Center, the biggest nonprofit well being supplier within the Seattle space.

Swedish is one in all a rising variety of respected hospitals and health systems — together with the Mayo Clinic, the Cleveland Clinic and the University of Miami — which have entered the profitable enterprise of stem cells and related therapies, together with platelet injections. Typical therapies contain injecting patients’ joints with their own fat or bone marrow cells, or with extracts of platelets, the cell fragments identified for his or her position in clotting blood. Many sufferers hunt down regenerative medication to stave off surgical procedure, regardless that the evidence supporting these experimental therapies is thin at best, Knoepfler mentioned.

Hospitals say they’re offering choices to sufferers who’ve exhausted customary therapies. But critics counsel the hospitals are exploiting determined sufferers and making the most of stylish but unproven therapies.

The Food and Drug Administration is making an attempt to close down clinics that hawk unapproved stem cell therapies, which have been linked to several cases of blindness and at least 12 serious infections. Although docs normally want preapproval to deal with sufferers with human cells, the FDA has carved out a handful of exceptions, so long as the cells meet sure standards, mentioned Barbara Binzak Blumenfeld, an legal professional who focuses on meals and drug legislation at Buchanan Ingersoll & Rooney in Washington.

Hospitals like Mayo are cautious to observe these standards, to keep away from operating afoul of the FDA, mentioned Dr. Shane Shapiro, program director for the Regenerative Medicine Therapeutics Suites at Mayo Clinic’s campus in Florida.

‘Expensive Placebos’

While hospital-based stem cell therapies could also be authorized, there’s no strong evidence they work, mentioned Leigh Turner, an affiliate professor on the University of Minnesota’s Center for Bioethics who has printed a sequence of articles describing the dimensions and dynamics of the stem cell market. 

“FDA approval isn’t needed and physicians can claim they aren’t violating federal regulations,” Turner mentioned. “But just because something is legal doesn’t make it ethical.”

For docs and hospitals, stem cells are straightforward cash, Turner mentioned. Patients sometimes pay more than $700 a therapy for platelets and as much as $5,000 for fats and bone marrow injections. As a bonus, docs don’t should wrangle with insurance coverage firms, which view the procedures as experimental and largely don’t cover them.

“It’s an out-of-pocket, cash-on-the-barrel economy,” Turner mentioned. Across the nation, “clinicians at elite medical services are lining their pockets by offering expensive placebos.”

Some affected person advocates fear that hospitals are extra fascinated with capturing a slice of the stem-cell market than in proving their therapies really work.

“It’s lucrative. It’s easy to do. All these reputable institutions, they don’t want to miss out on the business,” mentioned Dr. James Rickert, president of the Society for Patient Centered Orthopedics, which advocates for high-quality care. “It preys on people’s desperation.”

In a joint assertion, Pourcho and Swedish defended the web video.

“The terminology was kept simple and with analogies that the lay person would understand,” in keeping with the assertion. “As with any treatment that we provide, we encourage patients to research and consider all potential treatment options before deciding on what is best for them.”

But Knoepfler mentioned the company on the video make a number of “unbelievable” claims.

At one level, Dr. Pourcho says that platelets release growth factors that inform the mind which kinds of stem cells to ship to the location of an harm. According to Pourcho, these directions be sure that tissues are repaired with the suitable kind of cell, and “so you don’t get, say, eyeball in your hand.”

Knoepfler, who has studied stem cell biology for twenty years, mentioned he has by no means heard of “any possibility of growing eyeball or other random tissues in your hand.” Knoepfler, who wrote concerning the video in February on his weblog, The Niche, mentioned, “There’s no way that the adult brain could send that kind of stem cells anywhere in the body.”

The advertising and marketing video debuted in July on KING-TV, a Seattle station, as a part of an area existence present known as “New Day Northwest.” Although a lot of the present is produced by the KING 5 information workforce, some segments — like Pourcho’s interview — are sponsored by native advertisers, mentioned Jim Rose, president and normal supervisor of KING 5 Media Group.

After being contacted by KHN, Rose requested Swedish to take away the video from YouTube as a result of it wasn’t labeled as sponsored content material. Omitting that label might permit the video to be confused with information programming. The video now seems solely on the KING-TV web site, the place Swedish is labeled because the sponsor.

“The goal is to clearly inform viewers of paid content so they can distinguish editorial and news content from paid material,” Rose mentioned. “We value the public’s trust.”

Increasing Scrutiny

Federal authorities have not too long ago begun cracking down on docs who make unproven claims or promote unapproved stem cell merchandise.

In October, the Federal Trade Commission fined stem cell clinics thousands and thousands of for misleading promoting, noting that the businesses claimed to have the ability to deal with or remedy autism, Parkinson’s illness and different critical ailments.

In a latest interview Scott Gottlieb, the FDA commissioner, mentioned the company will proceed to go after what he known as “bad actors.”

With more than 700 stem cell clinics in operation, the FDA is first focusing on these posing the largest risk, resembling docs who inject stem cells instantly into the attention or mind.

“There are clearly bad actors who are well over the line and who are creating significant risks for patients,” Gottlieb mentioned.

Gottlieb, set to depart workplace April 5, mentioned he’s additionally involved concerning the monetary exploitation of sufferers in ache.

“There’s economic harm here, where products are being promoted that aren’t providing any proven benefits and where patients are paying out-of-pocket,” Gottlieb mentioned.

Dr. Peter Marks, director of the FDA’s Center for Biologics Evaluation and Research, mentioned there’s a broad “spectrum” of stem cell suppliers, starting from college scientists main rigorous scientific trials to docs who promise stem cells are “for just about anything.” Hospitals function someplace within the center, Marks mentioned.

“The good news is that they’re somewhat closer to the most rigorous academics,” he mentioned.

The Mayo Clinic’s regenerative medication program, for instance, focuses situations resembling arthritis, the place injections pose few critical dangers, even when that’s not but the usual of care, Shapiro mentioned.

Rickert mentioned it’s straightforward to see why hospitals are desirous to get within the sport.

The marketplace for arthritis therapy is big and rising. At least 30 million Americans have the most typical type of arthritis, with diagnoses anticipated to soar because the inhabitants ages. Platelet injections for arthritis generated more than $93 million in income in 2015, in keeping with an article final 12 months in The Journal of Knee Surgery.

“We have patients in our offices demanding these treatments,” Shapiro mentioned. “If they don’t get them from us, they will get them somewhere else.”

Doctors on the Mayo Clinic attempt to present stem cell therapies and related therapies responsibly, Shapiro mentioned. In a paper published this year, Shapiro described the hospital’s session service, through which docs clarify sufferers’ choices and clear up misconceptions about what stem cells and different injections can do. Doctors can refer sufferers to therapy or scientific trials.

“Most of the patients do not get a regenerative [stem cell] procedure,” Shapiro mentioned. “They don’t get it because after we have a frank conversation, they decide, ‘Maybe it’s not for me.’”

Lots Of Hype, Little Proof

Although some hospitals boast of excessive success charges for his or her stem cell procedures, published research typically paints a unique story.

The Mayo Clinic website says that 40 to 70% of sufferers “find some level of pain relief.” Atlanta-based Emory Healthcare claims that 75 to 80% of sufferers “have had significant pain relief and improved function.” In the Swedish video, Pourcho claims “we can treat really any tendon or any joint” with PRP.

The strongest proof for PRP is in ache aid for arthritic knees and tennis elbow, the place it seems to be protected and maybe useful, mentioned Dr. Nicolas Piuzzi, an orthopedic surgeon on the Cleveland Clinic.

But PRP hasn’t been confirmed to assist each a part of the physique, he mentioned.

PRP has been linked to critical issues when injected to deal with patellar tendinitis, an harm to the tendon connecting the kneecap to the shinbone. In a 2013 paper, researchers described the circumstances of three sufferers whose ache acquired dramatically worse after PRP injections. One affected person misplaced bone and underwent surgical procedure to restore the injury.

“People will say, ‘If you inject PRP, you will return to sports faster,’” mentioned Dr. Freddie Fu, chairman of orthopedic surgical procedure on the University of Pittsburgh Medical Center. “But that hasn’t been proven.”

A 2017 study of PRP discovered it relieved knee ache barely higher than injections of hyaluronic acid. But that’s nothing to brag about, Rickert mentioned, on condition that hyaluronic acid therapy doesn’t work, either. While some PRP research have proven extra positive results, Rickert notes that almost all have been so small or poorly designed that their results aren’t reliable.

In its 2013 tips for knee arthritis, the American Academy of Orthopaedic Surgeons mentioned it’s “unable to recommend for or against” PRP.

“PRP is sort of a ‘buyer beware’ situation,” mentioned Dr. William Li, president and CEO of the Angiogenesis Foundation, whose analysis focuses on blood vessel formation. “It’s the poor man’s approach to biotechnology.”

Tests of different stem cell injections even have didn’t dwell as much as expectations.

Shapiro printed a rigorously designed research final 12 months in Cartilage, a medical journal, that discovered bone marrow injections have been no higher at relieving knee ache than saltwater injections. Rickert famous that sufferers who’re in ache typically get aid from placebos. The extra invasive the process, the stronger the placebo impact, he mentioned, maybe as a result of sufferers grow to be invested in the concept that an intervention will actually assist. Even saltwater injections assist 70% of sufferers, Fu mentioned.

A 2016 overview within the Journal of Bone and Joint Surgery concluded that “the value and effective use of cell therapy in orthopaedics remain unclear.” The following 12 months, a overview within the British Journal of Sports Medicine concluded, “We do not recommend stem cell therapy” for knee arthritis.

Shapiro mentioned hospitals and well being plans are proper to be cautious.

“The insurance companies don’t pay for fat grafting or bone-marrow aspiration, and rightly so,” Shapiro mentioned. “That’s because we don’t have enough evidence.”

Rickert, an orthopedist in Bedford, Ind., mentioned fats, bone marrow and platelet injections needs to be provided solely by means of scientific trials, which rigorously consider experimental therapies. Patients shouldn’t be charged for these companies till they’ve been examined and proven to work.

Orthopedists — surgeons who focus on bones and muscle mass — have a historical past of performing unproven procedures, together with spinal fusion, surgical procedure for rotator cuff disease and arthroscopy for worn-out knees, Turner mentioned. Recently, research have proven them to be no simpler than placebos.

Misleading Marketing

Some argue that joint injections shouldn’t be marketed as stem cell therapies in any respect.

Piuzzi mentioned he prefers to name the injections “orthobiologics,”noting that platelets will not be even cells, not to mention stem cells. The variety of stem cells in fats and bone marrow injections is extraordinarily small, he mentioned. In fats tissue, solely about 1 in 2,000 cells is a stem cell, in keeping with a March paper in The Bone & Joint Journal. Stem cells are even rarer in bone marrow, the place 1 in 10,000 to 20,000 cells is a stem cell.

Patients are interested in regenerative medication as a result of they assume it’s going to regrow their misplaced cartilage, Piuzzi mentioned. There’s no stable proof that the industrial injections used as we speak spur tissue progress, Piuzzi mentioned. Although docs hope that platelets will launch anti-inflammatory substances, which might theoretically assist calm an infected joint, they don’t know why some sufferers who obtain platelet injections really feel higher, however others don’t.

So, it comes as no shock that many sufferers have bother sorting by means of the hype.

Florida resident Kathy Walsh, 61, mentioned she wasted practically $10,000 on stem cell and platelet injections at a Miami clinic, hoping to keep away from knee alternative surgical procedure.

When Walsh heard about a health care provider in Miami claiming to regenerate knee cartilage with stem cells, “it seemed like an answer to a prayer,” mentioned Walsh, of Stuart, Fla. “You’re so much in pain and so frustrated that you cling to every bit of hope you can get, even if it does cost you a lot of money.”

The injections eased her ache for only some months. Eventually, she had each knees changed. She has been practically pain-free ever since. “My only regret,” she mentioned, “is that I wasted so much time and money.”
