Emergency Suspension of Stem Cell Clinic Doc Kenneth Welker

The Oregon State Medical Board took emergency action to suspend the medical license of Dr. Kenneth Welker of Eugene, Oregon on Thursday.

Update: Unfortunately, the Associate Press (AP) story on this topic (discussed more below) contains numerous important mistakes including thoroughly mixing up embryonic, adult, and induced pluripotent stem cells (iPSC). Keep that in mind. Also, sadly another update this time in 2020, finds few actions still by state medical boards on stem cell clinics.

The emergency suspension was due in part to his injections of unapproved stem cell therapies into patients, some of whom had adverse side effects. The board viewed his practice to be a serious danger to patients. According to Nigel Duara of the AP:

“The board considers Dr. Kenneth Welker’s medical practice an immediate danger to the public.”

The Board has issued past recent orders on Welker. For example, in a September 20, 2013 action, the Board ordered Welker to stop doing stem cell interventions (order here).

Welker worked out of Oregon Optimal Health clinic, whose website is at this time unavailable, perhaps due to the suspension. The AP says “Welker is a trained surgeon who quit his practice to pursue alternative medicine in 2007.”

This Oregon clinic offered a variety of alternative treatments.

Oddly enough, Welker reportedly told patients that iPS cells (IPSCs) were the key to improving their health:

“In Welker’s case, according to the board complaint, he went much further, telling his patients that iPSC was the fix to their varied ailments: their arthritis, their patellar tears, their vertigo.”

However, it is not at all clear that he used iPS cell procedures. My guess is that iPS cells had nothing to do with what the doctor actually did.

He isolated fat and processed it from the patients before returning it to the patients, which doesn’t sound like an iPS cell procedure but more akin to SVF. However, details remain absent at this time as to how he processed the fat tissue/cells. It is unclear, for example, if Welker’s processing of the tissue constituted more than minimal manipulation, which could bring the FDA into the picture.

On the Oregon Optimal Health Facebook page, claims are made about how fabulous stem cell infusions are (see image above).

The AP reported on some of the problems that patients experienced. For example, Welker apparently injected “stem cells” into Patient J’s spine:

Welker used liposuction to remove fluid and fat from Patient J’s abdomen, processed it, then injected some of the processed solution into her spine and administered the rest intravenously.

“Within 5 minutes, Patient J complained of tingling in her body and both legs,” according to the order. “(Welker) noted that she had a high respiratory rate and elevated blood pressure with a lot of perspiration that lasted 45 minutes.”

Welker was surprised, and could not explain the reaction. He didn’t report Patient J’s reaction to the FDA.

It will be important to follow this story as it develops, but one lesson here is how risky unregulated stem cell clinics can be more generally.

There are probably more than 100 clinics similar to Oregon Optimal Health across just the US and many are run by doctors lacking thorough training in stem cells, transplantation, bioethics, and other important areas.

This case, the deaths of two patients of Dr. Zannos Grekos, a Florida “stem cell” doctor who had his license suspended, and other cases of harm outside the US including deaths at stem cell clinics, strongly support the need for appropriate regulatory oversight of US stem cell clinics to promote patient safety even as some paradoxically argue for less regulation.

  1. Contrary to your “unregulated” claim, it seems to me that the doctor and his practice were subject to licensing rules, as is made evident by the practice being monitored and suspended by a medical board.

    Perhaps, elsewhere you have explained (or will in future explain) what the rules for the practice of medicine are and why you see them as being deficient?

    I’d also be interested to hear the opinion of doctors regarding the licensing of scientists…

  2. Paul – Let’s put this into perspective. The Oregon state board and other state medical boards are a great way to protect patients. Why single this doctor out? You can learn of actions against doctors in the U.S. by visiting the state websites. Here is the one for Oregon – http://cms.oregon.egov.com/omb/board/Pages/Board-Actions.aspx

    Why aren’t you reporting on every doctor in every state that has had his or her license suspended? Why not report on the number of deaths each day due to FDA approved medications? This is one doctor, one bad apple. I can count on one hand the number of similar incidents that involve stem cell therapy. Compare that to the overall death rate from medications, surgeries, hospital error, etc. and it is not even a drop in the bucket.

    Would you suggest that the FDA step in and start regulating all medical practice? Should Congress pass a law to allow them to do so? How can you single out this doctor and not bring all the other doctors in the U.S.who have had license suspensions into the discussion? There are always going to be a few bad eggs and that is why state boards are so important to patients.

    It’s disingenuous to suggest that “unregulated stem cell clinics” (whatever those are since we do have regulations on stem cell treatment in the U.S.) are a major risk factor for patients in this country.

    1. At what point will a doctor’s actions with stem cells concern you? How disastrous does it have to be for you to care? Do many people have to be severely injured or die before you’ll get concerned?

      You yourself said to the Washington Post a few years back that a stem cell treatment made you so sick you thought you were going to die ( http://www.washingtonpost.com/wp-dyn/content/article/2008/08/29/AR2008082902517.html).

      Why now are you so seemingly tolerant of dangerous stem cell clinics lately? It seems really strange. I don’t get it.
