Show Notes

Millions of Americans are in pain. Arthritic joints make exercise difficult, even though moving is one of the best things we can do for joint pain. Pinched nerves can cause excruciating, long-lasting pain. The usual treatments, such as NSAIDs, may help ease the pain momentarily, but do nothing to help heal the underlying condition. What do you know about the new science of regenerative therapies?

The New Science of Regenerative Therapies

What is the price of pain relief for aching, arthritic joints? We’re not talking about the drugstore sticker on a bottle of ibuprofen. Instead, we are referring to the potential negative consequences of utilizing such medicines for temporary symptomatic relief when the joint continues to hurt for weeks, months or years. Even more powerful treatments, such as corticosteroid injections into the sore joint, don’t heal the cartilage. In fact, they may contribute to further deterioration as they suppress the immune system. Our guest offers other ways to treat joint pain with regenerative therapies.

Immune Mechanisms That Resolve Inflammation

Dr. Tom Buchheit is a pain management specialist who has worked with elite athletes as well as seniors to get them moving well again after an injury. One of the reasons exercise can be so helpful is that the right kind and amount of movement creates good inflammation. Unlike chronic inflammation that causes further harm, good inflammation helps the immune system switch to a different phase, one in which destructive pathways are resolved. The three pillars of exercise are aerobic exercise, muscle building exercise and exercise to improve balance. Together, these types of exercise help recovery and healing and can even help heal damaged nerves. NSAIDs like naproxen, celecoxib or ibuprofen can interfere with the good inflammation exercise creates. Rather than taking such a pill before a game or workout, it makes sense to wait and take it afterwards if you need it.

Will Exercise Wear Out Your Joints?

Injury can damage the joints, but the idea of osteoarthritis as a consequence of wear and tear seems to be a medical myth. Instead, we might think of osteoarthritis as a chronic wound that may need regenerative therapies to heal properly. Immune system building blocks like omega-3 fats in the diet and a wide palette of colorful produce can help with the healing. Movement itself is part of the healing process.

What Are the Regenerative Therapies?

PRP

Some of the therapies we think of as “new” have actually been in use for several decades. One of these is platelet-rich plasma, which was initially developed to help wounds heal. In this treatment, the doctor uses the patient’s own blood. The plasma with as many platelets as possible concentrated in it is then carefully injected into the painful joint. The idea, again, is to cause “good inflammation,” alerting the immune system that healing is needed here and encouraging it to flip into inflammation resolution mode. Not all studies of platelet-rich plasma (PRP) have shown benefit, but some of that may be due to using plasma that is not truly rich in platelets. Properly prepared PRP works especially well for ligaments and tendons, according to Dr. Buchheit.

MSC

If you hear someone talk of getting a “stem cell” injection, they are talking about MSC. They were originally misnamed mesenchymal stem cells, but would be better termed medicinal signaling cells. They too are derived from the patient’s own body. Rather than rebuilding cartilage, they also signal the immune system to switch from long-term damaging inflammation to short-term healing inflammation. This is also the idea behind prolotherapy, in which the therapist injects sugar water into the joint. That may sound like a placebo, but it can be effective at easing pain and helping healing.

Autologous Conditioned Serum

Dr. Buchheit describes another of the regenerative therapies, autologous conditioned serum. Blood is drawn and encouraged to clot; then the serum is injected into the troublesome joint. Clotting helps create powerful signals that healing is needed. This therapy is not widely available, as only about ten places in the US have the dedicated laboratories required to prepare ACS properly.

Hydrodissection

Dr. Buchheit also describes how to use injections to free up trapped nerves in a process called “hydrodissection.” This is often very helpful in alleviating chronic neuropathy. We conclude the episode with a brief reminder of how to stay healthy once you get nerves and joints feeling good again.

I’m Joe Graedon.

Terry

00:01-00:05

And I’m Terry Graedon. Welcome to this podcast of the People’s Pharmacy.

Joe

00:06-00:27

You can find previous podcasts and more information on a range of health topics at peoplespharmacy.com.

Exercise is critical for good health, but when your joints or nerves hurt, it’s hard to keep moving. What can you do? This is the People’s Pharmacy with Terry and Joe Graedon.

Terry

00:34-00:49

Most people rely on non-steroidal anti-inflammatory drugs. Millions take over-the-counter ibuprofen or naproxen every day. Others rely on prescription medicines such as celecoxib or meloxicam. What are the downsides?

Joe

00:50-00:54

Our guest today is an expert in regenerative medicine.

Terry

00:55-01:00

What does that mean? And how does it differ from the usual way to manage pain and speed recovery?

Joe

01:01-01:06

Coming up on The People’s Pharmacy, the new science of regenerative therapies.

Terry

In The People’s Pharmacy Health Headlines: flu season is pretty much over, but every year it takes a toll, especially among frail elderly people in nursing homes.

A new study published in JAMA Internal Medicine asked whether using Tamiflu preventively could reduce hospitalizations and death. Researchers reviewed records covering 404 flu outbreaks in 318 nursing homes. More than 35,000 residents were covered by the study.

When Tamiflu was given to at least 70 percent of the residents within two days of the first flu cases, there were dramatically fewer hospitalizations needed within the next two weeks. That’s in comparison to situations where Tamiflu was not provided as a preventive medicine.

If you ask most cardiologists what causes heart disease, the answer is likely to be LDL cholesterol. They might also mention triglycerides, lipoprotein A, and high blood pressure.

They probably won’t consider lead, but a study of over 42,000 American adults who participated in the National Health and Nutrition Examination Survey tracked lead levels over many years. Those with the highest levels of lead in their bones were more likely to die from heart disease or stroke.

People born in the 1930s and 1940s, before lead was removed from gasoline and paint, have the highest lifetime lead exposures. Further reduction in lead exposure should lead to lower rates of cardiovascular mortality. An editorial in the journal suggests that coronary heart disease is in part attributable to lead and other environmental exposures.

What is the cause of memory loss as people age? A recent study of mice suggests it might begin in the gut. Specifically, the scientists tracked microbiome aging throughout the lifespan. They found that gut bacteria producing medium-chain fatty acids accumulate with aging and drive inflammation. This, in turn, weakens the signal from the vagus nerve to the brain, with the result that the hippocampus falters. The hippocampus is critical to memory.

In this study, the scientists introduced phage viruses to target the parabacteroides, gut microbes, causing the trouble. They suggest such interventions might counteract age-associated cognitive decline, although, of course, mice are different from humans. We look forward to research that might demonstrate its feasibility in people.

Fibromyalgia is a painful and chronic condition that affects soft tissue. It also causes fatigue, brain fog, and sleep problems. Millions of Americans are affected by this somewhat mysterious condition.

A study published in JAMA Network Open reports that the combination of physical therapy and transcutaneous electrical nerve stimulation, also known as TENS, can reduce pain. Over 380 patients participated in the trial. Volunteers were randomized to receive PT plus TENS or physical therapy alone. After two months, those getting physical therapy plus electrical stimulation reported significantly less pain than those in the PT-only group.

The authors note that the findings demonstrate effectiveness of this non-pharmacological intervention in reducing movement-evoked pain and suggest that the benefits of TENS are clinically meaningful in this population.

With warmer weather, tick season is right around the corner. In fact, it’s already here in many parts of the country. Most people have heard of Rocky Mountain spotted fever and Lyme disease, but ticks can transmit over a dozen different diseases, from anaplasmosis and babesiosis to ehrlichiosis and alpha-gal syndrome. It’s estimated that more than 500,000 people could be treated for Lyme disease between now and the first freeze this fall.

But there is potentially good news on the horizon. Pfizer is teaming up with a French company to produce a vaccine against Lyme disease. It triggers your body to make antibodies to a protein on the surface of the Borrelia bacterium. These antibodies keep the Lyme-causing bacteria from infecting you and causing disease.

And that’s the health news from the People’s Pharmacy this week.

Welcome to the People’s Pharmacy. I’m Terry Graedon.

Joe

06:17-06:27

And I’m Joe Graedon. You’ve heard us praise the power of exercise for good health. But it can be hard to keep moving when your joints hurt.

Terry

06:27-06:44

The usual approach is to take a non-steroidal anti-inflammatory drug, such as ibuprofen or naproxen. That is a short-term solution, and it comes with a handful of side effects. What else could we do to alleviate joint pain?

Joe

06:44-07:11

To help us understand some new options, we are talking with Dr. Tom Buchheit. He’s done research on immune mechanisms that resolve inflammation and pain. He serves as an adjunct associate professor at Duke University and collaborates with colleagues at the Center for Translational Pain Medicine.

His new book is “Healing Joints and Nerves: Immune Stimulation and the New Science of Regenerative Therapies.”

Terry

07:13-07:16

Welcome to the People’s Pharmacy, Dr. Tom Buchheit.

Dr. Tom Buchheit

07:17-07:27

Thank you, Terry, Joe. It’s wonderful to be here.

I have to say, I’ve been listening to your show since 1998 when my wife and I moved to North Carolina, and it’s just a delight to be here. So thank you.

Joe

07:27-08:36

Well, thank you so much for joining us. You know, Dr. Buchheit, I’d have to say that if people ask us, and they occasionally do, what’s the one most important thing we should do for good health?

The answer is simple. We say exercise. Exercise is absolutely critical. Move your body. Even if it’s just for a walk every day, if you can. And if you can do more, so much the better. Terry is a black belt in karate. I love to play tennis. We love to move our bodies.

There’s only one problem. What interferes with exercise? Pain. Injuries. You know, when you exercise a lot, you sometimes hurt yourself, and then you have to take a break. And for people who really enjoy exercising and want to do it, that can be both psychologically and physically very challenging.

So help us understand your field and how to help people get back moving again once they hurt themselves.

Dr. Tom Buchheit

08:37-10:02

Well, Joe, you brought up a really good point. Exercise plays a very important part of health for all of us. And I think we increasingly know the reasons why. One of the core topics that I talk about and like to focus on is the importance of healing and our body’s innate ability to heal. We turn those healing mechanisms on by stimulating certain immune cells, and one of the most powerful ways of doing so is exercise.

Exercise does it. Good inflammation does it. Some other regenerative therapies do it. And these are all bound together by the same healing mechanisms. But you’re right, exercise is core to that.

The challenge a lot of people run into is that they have an injury. They have arthritis, a problem in a joint. They’re unable to do that. And their question is, how do they get back to that activity? What I use, I use the phrase orthopedic limbo. That individual is in orthopedic limbo. They have an issue that prevents them from pursuing their tennis or their karate or just walking the dog or spending time with friends. And they’re trying to figure out how to get beyond that and move again, but they’re not necessarily a surgical candidate.

So what can they do? And that’s one of the reasons I like to focus on these things that stimulate a healing response and stimulate recovery to function.

Joe

10:02-10:11

And we’ll talk a little bit more about some of those strategies because they’re really intriguing. But first, why is exercise so important?

Dr. Tom Buchheit

10:13-10:16

Exercise is important because it produces good inflammation.

Terry

10:18-10:21

Whoa, whoa, whoa, wait. Inflammation is good?

Dr. Tom Buchheit

10:23-11:23

That’s an important topic, right? I think a lot of people hear inflammation, they think immediately inflammation is always bad. We have to get rid of it. We have to suppress it. We have to drive it down.

And there are, and I think you’ve talked about this in your show before as well, but there are good components of inflammation. We have to be careful we don’t throw the wheat out with the chaff with that. So chronic inflammation is always bad, right? It damages tissues. It drives arthritis. It drives chronic pain.

But short-term, brief, and fairly strong inflammation is how we heal. If I had an ankle sprain and I bled into that ankle sprain, that injury, that inflammation is what heals that ligament eventually. You bleed, you release growth factors, you turn on these immune systems.

Exercise does that same thing, but it’s good inflammation. So I think of good inflammation as short, reasonably strong, and able to flip an immune switch that begins a healing cascade.

Terry

11:24-11:33

Dr. Buchheit, in “Healing Joints and Nerves,” you talk about the three pillars of exercise. What are the three pillars and why do we need three of them?

Dr. Tom Buchheit

11:35-12:23

Well, great question. There are certain tremendous advantages of aerobic exercise. We know that people who have a high aerobic capacity and who can exercise at high levels, it doesn’t matter if it’s running, swimming, playing tennis, that’s linked to longevity. We also know that muscle mass, and increasingly people talk about muscle mass being very important and strength being very important to strengthen joints. And we see this with studies of even arthritis patients who have less joint pain if they can strengthen the support structures of that joint.

And then, of course, balance is such a wonderful thing, whether it’s through balance exercises or yoga or tai chi, just such wonderful exercises that brings all this together of strength, stability, and the ability to stay on two feet without falling down.

Joe

12:24-12:52

I want to know how exercise helps recovery, because that’s, you know, we often hear, “Oh, ice and rest and, you know, just don’t do anything for a week or two,” because a lot of tennis players, they want to get back on the court as fast as possible, and they’re told, “No, no, no, no, no, no, you got to rest those joints, that you pulled a muscle, you better let it rest.” And you’re suggesting that exercise actually helps with healing.

Dr. Tom Buchheit

12:53-13:52

It absolutely does. And it helps with healing because it flips that immune switch and turns on this healing cascade. There was a study that I think showed this well. It was patients who had ankle injuries and they were immobilized in crutches after an ankle injury and they measured the cartilage in their knees as a marker after immobilization.

And they found out that those who were in crutches for long enough actually had less cartilage in their knees. Their knees were never injured, but it was the lack of exercise that decreased the health of their joint cartilage. So our bodies need this. They need intermittent stress.

And I think this… we have kind of fallen into this trap where we think all inflammation is bad. I would push back on that. I think we need to stress ourselves, whether it’s studying for an exam, whether it is playing a tennis match, whether it’s going for a brisk walk. Our bodies use stress and use these intermittent bouts of exercise to strengthen.

Terry

13:54-13:57

I’m assuming we stress ourselves appropriately.

Dr. Tom Buchheit

13:57-14:30

Exactly. And that’s the Goldilocks phenomenon, right? If you want enough stress. So to look at it kind of biochemically, if you look, there are a lot of inflammatory proteins that a muscle will release if it’s been exercised.

Matter of fact, some of those will go up a hundred fold and they cause some of the aches that we’re familiar with after a strong workout. But those same inflammatory proteins will then flip and help our bodies to produce some of the anabolic proteins and things that rebuild tissues and strengthen tissues.

Terry

14:31-14:35

How does exercise help nerves regrow? You’ve said it does.

Dr. Tom Buchheit

14:35-16:00

That’s a great question. And that came as a bit of a surprise to me when I started doing research on this a bunch of years ago. We all thought of, and I think a lot of the medical profession thinks of, well, once you have neuropathy, it’s just a done deal. You’re never going to recover from it. Your nerves are gone. And neuropathy is nerve pain. Right, nerve pain and nerve dysfunction from the nerve pain.

And it can be different kinds. There can be sciatica somebody experiences after a disc herniation in the spine. There can be dying back of the nerves somebody experiences because of diabetes or they’ve had chemotherapy in the past. Those nerves can recover. And exercise is actually one of the important tools to help those nerves recover.

It does a few… through a few things. Some of the growth factors I talked about that exercise releases. It also does it through these very small immune particles called exosomes that we researched in lab that I’ve researched and looked at for a long time now. And they also help nerves recover.

[If] we think about it, nerves are energy hogs. And anything we can do to improve their energy supply through mitochondria, mitochondrial function, is going to help the nerve to recover. And so exercise and some of these other therapies can improve nerve function. They may not help a nerve regrow from the back all the way down to the foot, but they can take the nerves that are already there and help them work better and help people function better.

Joe

16:00-16:36

One of the things that most physicians, not all, but most physicians, especially the orthopedists like to prescribe are the non-steroidal anti-inflammatory drugs. So if you sprain your ankle, if you hurt your shoulder, if your back is giving you trouble, out come the NSAIDs. And of course, they’re also available over the counter, Aleve, naproxen, ibuprofen, Advil. And so people have come to just love non-steroidal anti-inflammatory drugs. You’ve suggested that they might be counterproductive in some ways.

Dr. Tom Buchheit

16:37-17:20

Well, they can be. And anti-inflammatory medications, what we call NSAIDs, they can, in fact, impair the strengthening our body’s experience with a workout. And this has been looked at in patients, this has been looked at in laboratory studies of laboratory animal models, that if you slow down or stop the inflammatory response to exercise, you also impair the muscle building and the strengthening you get from that workout. So NSAIDs, sometimes we may need to take them for a severe headache or a pain that’s keeping us from moving.

But if we take them chronically, they impair the very healing mechanisms that our bodies need to stay healthy and recover.

Terry

17:20-17:26

Now, if you were to take an NSAID for a workout, when should you take it and why?

Dr. Tom Buchheit

17:26-17:30

That’s a great question. So I think the clear answer is after the workout, not before.

Joe

17:32-17:42

A lot of my tennis buddies call it vitamin “I” and they take it religiously before they go out on the courts. So you’re suggesting maybe not such a good plan.

Dr. Tom Buchheit

17:42-18:06

I think if one can hold off until after the workout and wait as long as you can, it’s better off than before. I think it’s probably better for our joints and our bodies to have a shorter workout without an anti-inflammatory than a longer workout with.

Now, that’s never been studied in a randomized controlled trial, but I think it’s a good idea to avoid taking it before whenever possible.

Terry

18:07-18:15

You’re listening to Dr. Tom Buchheit, an expert in pain management and founder of the Triangle Regen Medicine and Biologic Center.

Joe

18:15-18:28

After the break, we’ll learn about steroid shots in joints. What might work to ease osteoarthritis pain? You may have heard of PRP and stem cells. We’ll get the details.

Terry

18:39-18:42

You’re listening to The People’s Pharmacy with Joe and Terry Graedon.

Joe

20:18-20:21

Welcome back to The People’s Pharmacy. I’m Joe Graedon.

Terry

20:21-20:39

And I’m Terry Graedon.

Joe

20:39-20:48

Today on The People’s Pharmacy, our topic is healing joints and nerves. What are regenerative therapies and how do they work?

Terry

20:48-21:14

Our guest is Dr. Tom Buchheit, founder of Triangle Regen Medicine and Biologic Center. Dr. Buchheit was chief of pain medicine at Duke University from 2013 to 2019 and is an adjunct associate professor there. His new book is “Healing Joints and Nerves: Immune Stimulation and the New Science of Regenerative Therapies.”

Joe

21:15-21:50

Dr. Buchheit, corticosteroids, very popular on the tennis court. You know, “Oh, my shoulder hurts. I need a steroid shot. Oh, my back aches.” Another steroid shot. “Oh, my knee is giving me trouble.” Another steroid shot. Doctors love them because people feel better oftentimes immediately after or within a few days and it lasts sometimes a couple weeks for some people maybe as long as a couple of months, but there’s a downside. What is it?

Dr. Tom Buchheit

21:50-23:48

Well, there is a downside, and it is true that a steroid injection can produce rapid pain relief, and can be helpful in some people to get them back to the gym, get them back to the workout.

My concern with steroid injections or corticosteroid injections is the repeated use of them. There was a study done now almost 10 years ago, and it was a randomized control trial looking at individuals who had osteoarthritis of both knees, and one group had saline injections into the knees. The other group had corticosteroid injections. And at the end of two years, there was no difference in the pain, which didn’t really surprise a lot of people because we know steroid injections tend to be shorter lived.

But the individuals that had repeat steroid injections actually had less cartilage in their knees than the ones that had saline. And I feel like that study was a bit of a wake-up call to all of us. And I did a lot of steroid injections at the time as well because patients seemed to do well with it. But it made me start rethinking how I was approaching this concept of how do you treat someone with joint pain, some arthritis, they don’t need surgery, again, the patient [in] orthopedic limbo.

We’ve relied on corticosteroid injections as a bit of a crutch, and I think we need to flip this paradigm and think about how do you improve cartilage health, how do you improve tissue health? This year is the 75th anniversary of the first corticosteroid injections that were done for arthritis pain. And it was a remarkable event.

But interestingly, I’ve gone back and I’ve read a lot of the historic literature on corticosteroids and their use in arthritis. And the physician who published the paper noted that 37 of 38 of his patients did extremely well after the steroid injections. But what he didn’t emphasize is some of the patients required up to 17 injections per year to maintain that.

Terry

23:48-23:49

Oh, my.

Dr. Tom Buchheit

23:49-24:00

And I think that’s the part that we’ve been missing within the medical world, is that a steroid injection can be an important tool, but I would argue it’s an overused tool in a lot of settings.

Terry

24:01-24:15

Well, 17 injections a year definitely sounds like it’s being overused. And one of the things that steroids do is they suppress the immune system. What’s the impact of long-term immune system suppression?

Dr. Tom Buchheit

24:17-25:22

Well, gosh, there’s a lot of things that [it] would do. Obviously, we could go into, you know, bone health and bone density. We could go to the endocrine system and looking at, you know, someone who is borderline diabetic who becomes frankly diabetic after repeated steroid injections.

We can look at tissue healing as well. But if I kind of focus on the cycle, I think we need to think of our bodies as cycles, right? We cycle day and night. We sleep. We wake up. And exercise and this immune stimulation that keeps our joints healthy is also a cycle. It’s a cycle of exercise and recovery.

And anyone who’s trained knows this inherently. You have hard workout days. You have recovery days. And I think if we use tools like steroids or anti-inflammatories continuously, we remove those necessary cycles of stress and recovery, stress and strengthening. And steroids, I think, act in some ways have similar effects as the anti-inflammatories do. And I can quote, we can talk about a study as well that dives into that.

Joe

25:23-25:52

Well, I’d like to talk about one of the reasons that a lot of people get steroid injections and one of the reasons why they take a lot of the anti-inflammatory drugs, and that’s osteoarthritis. And it can affect your fingers. It can affect your shoulders. It can affect your knees. It can affect your hips. It can affect just about every joint in your body. And I remember someone saying a long time ago, well, exercise is going to make it worse.

Dr. Tom Buchheit

25:53-27:48

Right, that’s the old wear and tear hypothesis and that was the hypothesis about osteoarthritis for years which is that well you just you’re just wearing your joints too much and they’re just wearing down.

That ignores the fact though that exercise restores cartilage health, and you know some people talk about well someone loses weight and they have less joint pain and it must be less weight on their joints and less wear and tear. But the hand arthritis also gets better if you lose weight.

And so I think it’s an issue of a systemic chronic inflammatory problem that’s improving with weight loss. We’ve then moved from the wear and tear hypothesis to the inflammatory hypothesis of arthritis. And it made sense. We can see inflammation on ultrasound if we do an ultrasound exam of a joint. You can pull out fluid, and it looks inflammatory if you look at it under biochemical analysis. The patients feel the inflammation, but if you treat the inflammation, it doesn’t improve the disease state. And that’s been shown so many times.

There have been at least four studies of strong inflammation suppressors in the rheumatoid arthritis drugs that have been looked at for osteoarthritis. They did not work. There have been studies of corticosteroid injections. Again, they tend to worsen the problem, not make it better.

The concept that I think we need to focus on is osteoarthritis is a chronic wound. And we need to think about how to heal the wound. If you heal the wound, the chronic inflammation also improves as well. And that explains, I think, the chronic wound concept explains why studies have failed in the past and why some of the therapies we do now, such as some of the regenerative therapies, can actually have a role.

Terry

27:49-28:09

Well, maybe you could tell us a little bit about what could work for osteoarthritis, because so far, we’ve talked about things that are less than ideal. The steroid injections, the NSAIDs, those are the most common. And there have to be things, maybe even a lot of things, that can be useful.

Joe

28:09-28:22

Well, first, what the heck is regenerative therapy? And second, why would exercise, because you’ve sort of alluded to that, be helpful for osteoarthritis? So give us the one-two punch.

Dr. Tom Buchheit

28:23-28:36

I always think of it as we start with a healthy diet, healthy fruits, vegetables, healthy fats, and exercise to that. And that is the core, I think, of keeping joints and nerves healthy.

Terry

28:36-28:37

And the rest of us.

Dr. Tom Buchheit

And the rest of the body as well, right? What’s good for your heart tends to be good for your joints as well, right? It’s enough for a lot of people, but it’s not enough for everybody. And it’s not enough for people who have had injuries in the past. It’s not enough people who have a systemic inflammatory issue going on.

And that’s when I think about layering on what some people call regenerative therapy. Some people may call it an ortho-biologic. These are ways of stimulating those immune cells I talked about and pushing them into a state where they are resolving and building tissues again, where they’ve been suppressed in the past and they’re kind of low level. They’re chronically inflamed. They’re not behaving well.

You need to push them into a new state, this resolving state. And I think of it not as suppressing inflammation but resolving it. And it might sound like a little bit like splitting hairs a bit. But if I think of suppressing inflammation or fighting inflammation, I think of you’re putting a drug on it to tone it down temporarily.

When I think of resolving inflammation, I think of our body’s natural processes that resolve it. There are some wonderful fats that do this. They’re called SPMs. They’re derivatives of omega-3 fatty acids. Our bodies use those and other compounds to naturally resolve inflammation. Matter of fact, in the lab, some of those compounds are more powerful than morphine in animal models of nerve pain to resolve inflammatory pain in models.

Joe

30:04-30:07

Wow, that’s amazing. Tell us, how do you do that?

Dr. Tom Buchheit

30:08-30:10

Well, our bodies make these compounds.

Terry

30:10-30:22

And you say they make them from omega-3 fats like fish oil or walnut oil or the fats that we get in very small quantities from dark green leafy vegetables.

Dr. Tom Buchheit

30:23-30:53

Precisely. If we eat a diet rich in healthy fats, as you pointed out, from walnuts, nuts, cold water fishes like salmon and anchovies and tuna, as long as it’s not too high in mercury, our bodies take those fats and they make other compounds from them. And those other compounds will resolve inflammation.

They work with the leafy green vegetables and all the colorful vegetables that you all have talked about that are so important to overall health.

Terry

30:53-30:55

We love talking about colorful vegetables.

Dr. Tom Buchheit

30:56-31:13

But that all works together. And that, to me, is the foundation of really regenerative medicine is what our bodies are already doing and how can we promote those activities themselves. A lot of people focus on a procedure and injection, and they can be helpful, but we have to start with our own bodies.

Joe

31:13-31:43

So it sounds like diet is critical and the healthy fats, the omega-3s are especially beneficial. So your body can do this resolving stuff. And exercise is also important, presumably if it’s, you know, mild exercise, if you’ve injured yourself so that you don’t re-injure yourself.

But what are some of these other agents, this regenerative process that you’re talking about that you practice when you see patients who have had injuries?

Dr. Tom Buchheit

31:43-33:05

Yeah, great question. I would put them in three different categories, things like platelet-rich plasma, which we’ll talk about, stem cells, or something called autologous conditioned serum. Some people know it as the Regenokine program. PRP or platelet-rich plasma is probably the one I’d start with because it directly activates our own healing cascade.

Interestingly, back to my analogy of the wound in a joint, PRP was first used to treat wounds. It was first used by a wound surgeon published in 1986. It’s been around for a while. Then it was used in the oral surgery field to heal non-healing wounds. And then it kind of leapt into the world of arthritis and nerve issues and things like that. But what it is, is if you take blood and you spin it down and you collect the platelets and the white blood cells there, they can act with the growth factors and act in a way to flip that immune switch I was talking about to start to rebuild tissues.

So it’s a way to almost use that, almost like exercise. It’s almost like exercise in a tube in a way. You take that blood product and you inject it onto a knee or a shoulder or hip, and it further turns on those healing mechanisms that our body can have, but aren’t always strong enough by themselves.

Joe

33:05-33:17

Now, let’s make it very clear. We’re not talking about someone else’s blood. We’re talking about our own blood is being removed. And I assume it’s not gallons. It’s just a little bit. How much?

Dr. Tom Buchheit

33:18-33:30

Well, actually, that’s a very good point. You need a fair amount. You need a fair amount because you have to make sure the PRP dose is right. So how much is 60 to 120 milliliters?

Joe

33:31-33:33

So for people who are not metric.

Terry

33:34-33:40

So a cup is roughly 250 milliliters. So we’re talking less than a cup.

Joe

33:40-33:44

Less than a cup. Right. So it’s not gallons. It’s a little bit of blood.

Terry

33:44-33:46

Maybe a half a cup, more or less. Half a cup, a cup.

Joe

33:47-33:57

And you’re removing that blood, and then you’re spinning it down, and you’re extracting the platelet-rich plasma.

Dr. Tom Buchheit

33:57-33:59

Exactly. Now…

Joe

33:59-34:00

And re-injecting it.

Dr. Tom Buchheit

34:00-34:20

And re-injecting it. PRP has become quite controversial. One of the reasons is because there have been a couple of very large trials that have shown it hasn’t worked.

But if you go back and analyze the studies, which I’ve done with some colleagues, it turns out that if the plasma isn’t rich in platelets, it doesn’t work. And it sounds a bit, you know, axiomatic.

Terry

34:21-34:26

Right. So you have to have the right stuff in order for it to work the way it’s intended.

Dr. Tom Buchheit

34:26-34:26

Exactly.

Joe

34:27-34:31

So is it a little less controversial now? Are there studies demonstrating benefit?

Dr. Tom Buchheit

34:32-34:44

There are with high doses, and I think that’s the key. If the dose isn’t right, it just doesn’t work. And that’s why it’s important. And one of the things that I do is I measure the doses of every PRP to make sure that dose is correct.

Joe

34:45-35:03

So our listeners and a lot of your colleagues learn from stories. Can you share a story with us about somebody who came to your practice in pain and maybe not able to exercise, and that person benefited from PRP?

Dr. Tom Buchheit

35:05-35:24

I think it’s a common scenario. I would use the scenario of someone who’s had a prior ACL tear or a lot of knee ligament tear. Especially young women athletes seem to have this quite commonly. The problem with these tears is that it sets them up for early arthritis.

Joe

35:25-35:28

And we know the surgery itself has some issues.

Dr. Tom Buchheit

35:29-36:15

Right. Well, joint replacement surgery can be very successful, but you also don’t want to do that when you’re 45 years old and still active because you may wear out your joint. You might wear out the replacement.
