Dr. Nathan Wei - Arthritis Treatment: A Potential Fountain of Youth?





Imagine this… What if there were a real Fountain of Youth for arthritis sufferers?  Well… perhaps there is.
A featured story, "Stem Cell Treatments for Zoo Animals Hold Promise for Humans” appeared this past year on ABC News (Newcomb) and underscored the interest that both scientists as well as lay people have in the use of stem cells to repair and treat degenerative conditions. 

"We just extract them, concentrate them, ..wash them and … readminster them. Inject them in your heart or your knees, wherever you need them," Dr. Eckhard Alt told ABC Station KTRK-TV in Houston after treating an arthritic pig at the Houston Zoo."
So... why is this technology so important?

Osteoarthritis is the most common type of arthritis and is one of the most disabling conditions in developed countries according to the World Health Organization. Worldwide estimates are that at least 10 % of men and 18% of women past the age of 60 have symptomatic osteoarthritis. These figures undoubtedly underestimate the true incidence of the problem.  While age is the primary predictor of this ailment, genetics and a history of previous trauma also play significant roles. Other risk factors include obesity, physical inactivity, smoking, and excessive use of alcohol.

While many other types of arthritis can be controlled and symptoms alleviated, there are no such treatments available that can reverse the wear and tear that causes osteoarthritis!
Couple these sobering statistics and the lack of effective treatments along with the ever-growing population of Baby Boomers and a health crisis is in the making.

The numbers tell the story.  According to figures supplied by the Healthcare Research and Quality agency of the federal government, there were 288,471 total hip replacements in 2009, nearly half of them in people under the age of 65. Knee replacements soared from 264,311 in 1997 to 621, 029 in 2009… and more than tripled in the 45-to-64 year-old age group.

So what can be done other than to subject people to having metal and plastic hammered into their joints? And possibly suffer from the complications and side effects associated with these procedures…
Recently, there has been interest in the use of autologous, also known as mesenchymal, stem cells to help reverse arthritis damage. Stem cells (SCs) are cells that have not yet differentiated into a specific tissue type. They are "blank slate" cells. SCs have the ability to multiply and divide, given the proper environment.  This property makes them attractive for treatment of degenerative diseases like arthritis.

Here’s how it works: SCs are obtained from bone marrow, fat, or blood, and they are concentrated to provide a maximum number of cells in the smallest possible volume. These cells are capable of contributing to both repair as well as regeneration.  Adult SCs are often referred to as "repair SCs."
Here are five tips about stem cells (SCs) for arthritis treatment:

1. There are four types of SCs being studied. They are embryonic SCs, donor SCs, induced pluripotential adult SCs, and finally autologous SCs. Of these four, only two, donor SCs and autologous SCs have been used in either animals or humans to treat arthritis.

2. The results of SC therapy appear to be dependent on the following factors: age of the patient, body mass index (BMI), extent of cartilage loss, and the technical expertise of the center performing the procedure.

3. The procedure for arthritis is more than just injecting the SCs into the arthritic site. There is a need for some type of acute injury to help stimulate the stem cells to multiply and divide. Special guidance using arthroscopy- a small telescope inside the joint- and diagnostic ultrasound is necessary.

4. Possible complications of SC treatment can vary. As with any procedure, infection is the primary concern.

5. In the proper hands, autologous SC treatment can be successful. Early data indicating an improvement in cartilage thickness in the treatment of osteoarthritis of the knee has been published by our center.
