A website for five affiliated , hails a breakthrough for Parkinsons disease:Stem Cells Replace Damaged Nerves, Reverse Symptoms.
For those of you whose lives or whose loved ones lives have been upended by chronic or incurable conditions such as Parkinsons, thats just the kind of breakthrough youve been waiting for.
But today, Im going to pass along some advice about these and other for-profit stem cell treatments that you probably dont want to hear:Steer clear of them. Theyre probably taking advantage of you and its probably unproven, says Lawrence Goldstein, director of the atUC San Diego Health.
Stem cell science is a relatively new field. Stem cells hold for medicine because of their ability to develop into different types of cells in the body, and to repair and renew tissue.
But so far, the only stem cell treatments approved for wide use in the U.S. involve stem cell transplants from bone marrow or blood for patients with certain cancers and other disorders, says Sidney Golub, director of the Sue and Bill Gross at the University of California, Irvine.
Meanwhile, dozens of experimental stem cell treatments are being tested across the country in clinical trials on human subjects.
There are some really exciting developments showing great promise, but they are unproven at present, Golub says.
If most stem cell therapies are unproven, how is it that offer costly stem cell treatments for both cosmetic and medical purposes, ranging from spinal cord injuries to ?
California has 113 of these clinics, more than any other state, according to stem cell researchers of the University of Minnesota and of the University of California, Davis. Florida comes in second with 71, followed by Texas with 37.
Ask EmilyMany of these clinics say they use stem cells derived from patients own fat and, for related reasons, argue that their treatments are exempt from the U.S. Food and Drug Administrations rigorous approval process.
Their websites show heart-wrenching from patients who have undergone treatments and believe they have benefitted. The treatments can cost $15,000, $25,000 or more, and generally arent covered by health insurance.
If youre swayed by the testimonials, if youve tried every other treatment, and even if you have the money to burn, you should still steer clear, according to nearly every expert I consulted.
If somebody is telling you something thats too good to be true, its too good to be true, Golub says.
In addition to spending thousands of dollars on a therapy that may not help, you could experience undesirable medical side effects, they warn.
The risk is far greater than the potential benefit, says Mary Bass, director of public policy at , a patient advocacy group that supports stem cell research for chronic diseases and injuries.
There are really no shortcuts in the scientific discovery process. Shortcuts come at grave cost to patients health, now or down the line, Bass says.
The FDA, too, says in a statement for consumers that it is that patients may be vulnerable to unscrupulous providers of stem cell treatments that are illegal and potentially harmful.
Kevin McCormack, director of patient advocate outreach for the (CIRM), the states stem cell agency, acknowledges that patients dont want to hear this kind of advice.
Theyve often explored every other option and dont have anything left, McCormack says.
But there may be something you can do, he says: Search for a scientifically sound clinical trial that is testing a stem cell therapy for your condition.
One trustworthy place to look, McCormack says, is the three clinics in Southern California specializing in stem cell clinical trials that are funded by CIRM. They have more than for conditions ranging from HIV to ovarian cancer, he says.
If theres something at one of those clinics, you know its legitimate and as safe as can be, McCormack says.
To find other stem cell clinical trials, start with the government-run database.
But be cautious. Some for-profit stem cell clinics post on that site, and patients who want to participate in their studies for the cost of the treatment.
If you identify a trial that might fit your situation, do some digging, says Cathy Danielson, based in Oregon.
Start asking questions, start posting on online forums, she says. Ask who funded it. Follow the money.
Goldstein urges patients to look for trials that are conducted by academic medical centers or non-profit medical institutions, and to ask study sponsors if they have received FDA approval for their trials.
Patients will recognize legitimate clinical trials because, in general, they wont be charged for the cost of the treatment, he says.
Finally, if you find a trial, theres no guarantee youll receive the experimental stem cell treatment. Thats because in most trials, some participants chosen randomly will receive either a placebo or the current standard of care, while others will get the experimental treatment.
In other words, there are obstacles to obtaining stem cell therapy at this point.
But things are hopeful, Bass says.
Were really on the verge of . The hard part is remembering to have the patience and understanding about the scientific discovery process.
