The importance of Bone Mineral Density Exams (DXA scans)


The Importance of Bone Mineral Density Exams (DXA scans)

A dual-energy absorptiometry (DXA) scan can provide a snapshot of your bone
health. This test determines bone mineral density (BMD) and helps in establishing
fracture risk, and, with serial testing, is a way to measure response to osteoporosis
treatment. The most widely recognized test for determining BMD is the central DXA
scan. It is painless - similar to having an x-ray but much less radiation. The scan
measures bone density at your hip and spine. (Often, a scan of the forearm will also
be performed during central DXA testing.) Peripheral bone density testing measures
density at the wrist, finger, or heel and are typically used for screening purposes only.

DXA scans measure your bone mineral density and compares it to that of an 
established norm or standard to give you a score. Although no bone density test
is 100-percent accurate, the central DXA can be an important predictor of 
whether a person will have a fracture in the future. Most commonly, DXA results
are compared to the ideal or peak bone mineral density of a healthy young adult,
and given a T score. A score of 0 means your BMD is equal to the norm for a
healthy young adult. Differences between your BMD and that of a healthy young
adult norm are measured in units called standard deviations (SDs). The more 
standard deviations below 0, indicated as negative numbers, the lower your BMD 
and the higher your risk of fracture.

The National Osteoporosis Foundation (NOF) and the U.S. Preventative Services Task
Force (USPSTF) recommended osteoporosis screening with DXA for women 65 years
and older, and for men over 70. Earlier screening is recommended for both groups if risk
factors are present. (Risk factors are such things as family history of osteoporosis, 
weight under 127 pounds, history of smoking or excessive alcohol consumption, poor
diet, etc.)

A recent review published in the Journal of General Internal Medicine determined that
too few women are getting bone density scans. Researchers examined the medical 
records of 51,000 women aged 40 to 85 living in California and determined that only
57.8% of women aged 65 - 74 and 42.7% of women over age 75 received DXA
screenings. Even with women age 60 to 64 with at least one risk factor, only 58.8%
had a DXA. The researchers concluded that DXA screening is being underutilized.

DX Severe Osteoporosis: Part XII - Could TOO Much Exercise Cause Osteoporosis?



This is Part XII in a multi-part essay chronicling my personal experience with osteoporosis. In this series I have been taking readers through the diagnostic and treatment phases of my care that began over 18 years ago when I was diagnosed with severe osteoporosis. Over the years, the combination of experiencing multiple fragility fractures along with an intense immersion into the study of bone pathophysiology has given me a unique understanding of this disease. If you are just joining the series, I encourage you to skim through the previous DX Severe Osteoporosis essays on my blog (at: www.osteonaturals.com as they provide background to each new installment. It is my hope that this series will provide you with a better understanding of osteoporosis in general, plus a few "pearls" that you may be able to incorporate into your own quest for better bone health. If you have been reading the essays all along...welcome back.    Dr.M


Osteoblasts and osteoclasts have a give-and-take relationship, and their activities are linked. As with any couple, their interactions must stay in balance for marital happiness to be maintained; the harmony of bone depends upon a similar balance. The tricky thing is that resorption, like any form of demolition, is faster than re-building. To offset this, bones produce larger numbers of osteoblasts, and these plentiful cells control the overall activity of osteoclasts.

If the coupling mechanism that balances the activities of osteoblasts and osteoclasts gets out of sync, osteoclasts may begin to resorb more bone than the osteoblasts can replace. Low bone density, and eventually osteoporosis, is the result. On rare occasions it is the osteoclasts that are underactive, resulting in too much bone, a condition called osteopetrosis. It is the balance, and the communication aspects, between the processes that is crucial, as with any relationship.

The communication system between bone cells is a series of linked stimuli and responses. Problems arise when signals are either blocked or amplified. If signals are muffled, the music that coordinates the cells' activities becomes too slow; if they are inappropriately amplified, the notes become distorted and the tempo too fast. In either case the dance between the bone remodeling partners, the osteoblasts and osteoclasts, gets out of step and bone density is lost. The molecules that conduct the music are cytokines, growth factors, and glycoproteins--all of which are woven throughout the bones' collagen foundation to orchestrate the periods of active remodeling.

At the cellular level, the current of our aliveness is carried by metabolic cascades linked through a series of biochemical interactions which adjust the body's state of being to demands being made of it. Cytokines are proteins that are involved in a host of different functions throughout the body, and which can stimulate or inhibit these cascades. They can even direct cells to live or die. It was the cytokines' involvement in mounting the body's immune defenses that caught my interest. Inflammation, as you will remember, is the immune system's response to injury. Whether the injury is the result of chemical, microbial, or physical assault, the body reacts with an increase in blood flow and the release of disease-fighting white blood cells to the area. Heat, redness, pain and swelling are the noticeable consequences of this swift and potent defense.

An athlete's life such as mine is characterized by intense engagements of body and will: inflammation is the mark left by the fires of this passionate encounter. Left to smolder, those hotbeds cause long-term damage to tendons, joints, and even bone. No matter where the inflammation originates—autoimmune problems, toxic gut, glucose imbalances, oxidative stress—the immune system's response will be to flood the body with a deluge of pro-inflammatory cytokines.

Because some of the same cytokines that are active in immune reactions are involved in bone resorption, I looked further into this important link between the inflamed tissues of my hip and the scorching erosion of the bone. One of these cytokines, interleukin-1 (IL-1) stimulates the production of PGE2, a powerful prostaglandin involved in the inflammatory process. Il-1 also happens to be one of the most powerful stimulators of bone resorption.


Another cytokine, interleukin-6 (Il-6), not only stimulates the production of the bone-eating osteoclasts, but it can also increase their destructive potential by extending their normal lifespan. Levels of this cytokine are also high in the inflamed tissues of an injured joint. The link between bone resorption and inflammation was becoming clearer.

And there was more: when Il-6 is elevated it can decrease the synthesis of cartilage proteoglycans, the water-loving molecules in joints whose synthesis depends on glutamine—the same glutamine which is depleted by both Gilbert's syndrome and intense exercise. Combining Gilbert's with elevated Il-6 could severely limit the production of proteoglycans, taking the bounce right out of joint cartilage, and stripping its ability to absorb the compressive forces of exercise. Take the resilience out of cartilage and even low-level activity can be destructive to joints and the surrounding bone.

One of the pro-inflammatory cytokines, tumor necrosis factor (TNF), is from a family of molecules that help regulate bone cell activity. Another important member of that family is receptor activator nuclear kappa-B ligand, or RANKL for short. (I talk A LOT about this molecule in my book, The Whole-Body Approach to Osteoporosis.) A ligand is a communication molecule. This particular communication molecule, RANKL, is released by the osteoblasts and attaches to a special membrane receptor that goes by the acronym RANK, on an osteoclast precursor cell. The
precursor cell of an osteoclast is a type of white blood cell (thus the link to the immune system and bone). By activating this receptor, RANKL has keyed the precursor cell to develop into an osteoclast. So it is through the cytokine RANKL that osteoblasts control osteoclastic activity.

The key, at least for me, is that RANKL-induced aggressive bone resorptin can be stimulated by the over-production of pro-inflammatory cytokines and these same cytokines are capable of blocking osteoprotegerin (OPG). OPG is a "safety net" molecule released by osteoblasts that can prevent excess RANKL from over stimulating osteoclastic activity. With my N-TX (bone resorption marker) spiked so high, excessive osteoclastic activity in my bones was obvious. the linkage between stress, over-production of inflammatory cytokines, and the resulting over stimulation of the RANKL/RANK system suggested a trail to follow—a trail that might reveal the destructive pattern whose effects were showing up in symptoms and lab tests.

The athlete may not always be able to see it but high level competition is stressful. When I was training hard, I didn't think of it as stress, it was just what I did...who I was. But with pro-inflammatory cytokines making a clear link between bone loss and inflammatory states, I began to see my sports life in a different light. Could all of those miles that I ran, biked, and swam actually have contributed to the bone loss instead of stimulating its formation as we generally assume? The impact of healthy amounts of weight-bearing exercise is significantly different than flogging your body for hours upon hours, year upon year—especially if there is insufficient awareness of nutritional needs and an another underlying metabolic disorder (in my case Gilbert's).

Now the words of the acupuncturist began to make more sense. "A constitution dominated by the fire element, and the smell of being scorched." Had I done more than just bruise my wings? maybe I had been literally "scorched" by an unrelenting inflammatory cascade within me. An inability to limit the activity of the pro-inflammatory cytokines would  continually fuel smoldering fires and steadily sap the bones' strength. Now I saw that I had never given the time or the extra nutrients necessary for my body to recover between the intensity of workouts. When the heat is kept up non-stop and the furnace is never allowed to cool between engagements, the walls can crack...and the bones will break.

DX Severe Osteoporosis: Part VIII - Implicate Medicine



This is Part VIII of a multi-part essay about my own personal experience with osteoporosis. I will be taking you through the diagnostic and treatment phases of my care in hopes that it provides you a better understanding of osteoporosis in general, and pearls that you can use to better your own bone health.


                              "So the relationship of each moment in the whole of all the
                              others is implied by its total content: the way in which it "holds"
                              all the others enfolded within it."
                                               David Bohm, Wholeness and the Implicate Order



My constitution was fire, according to the acupuncturist. Looking back over my life and the intensity with which I approached things...well, I could relate to that assessment. But the smell of being "scorched"...that was just embarrassing...

Bone has three main functions: it supports the frame, protects organs from hard knocks, and acts as a reservoir for energy (fat) and minerals. I had a hunch that it was the last that would hold the most clues to the cause of my osteoporosis, especially since the biopsy showed that my bones were gaunt, with thin, disconnected trabeculae. They looked totally spent—scorched from years of, well, that was the question. Years of what? Malabsorption of nutrients? But the doctor had said I didn't have any absorption issues. Could it have been all those years of training in athletics? With my eyes focused on making the US Olympic Team since I was 13 years old, I had certainly stressed my body to the core. Had it been all those years of stressing my adrenal glands, stressing the overall functions of my body, that had sucked the energy out of me. Could those years have sucked the reserve function right out of my bones? There are lots of athletes who train hard for years and years and don't end up with osteoporosis. So that, at least by itself, wouldn't make sense either. But there was no denying, from the biopsy, it certainly looked like my bones had given just about all that they could give. And now, at the age of 45, all that was left was just empty chambers. And it looked as if they had been running on empty for quite some time.

The endocrinologist had ordered over 30 lab tests but everything was coming up normal, or at least that was his interpretation. At first I just went along with what he said; after all, his expertise on the subject was obviously considerably greater than mine. But, by a year into this mess (of being diagnosed with osteoporosis) my understanding of the technical aspects of bone loss improved and I began to look back over the lab tests more closely. While they were mostly pretty good, I noticed that some of the results were just a little off, just a little out of the normal reference range. I began to wonder, could these have meaning, as they relate to osteoporosis, that the doctor may not have understood?

Doctors focus on body parts and body fluids to help them understand a disease. But it's really impossible to understand everything...every slight variance in lab test and every "minor" symptom a patient presents with. And even if a doctor did understand these variances, would they try to put all those bits of information together, like pieces of a puzzle, in an effort to understand the patient as a "whole?" For example, I had told my endocrinologist that my skin was sometimes extremely sensitive, at times I was irritable (for me that was really unusual), and my stomach often hurt after long intense runs. I had also told him that I sometimes felt a slight overall body weakness. I couldn't really describe some of these feelings very well and I guess my ability to compete on a high level in road races and triathlons put him at ease that these vague symptoms weren't from something terrible brewing. In fact, he didn't seem to be interested in any of these symptoms, and as for the slightly-off lab work, that was quickly tossed aside.

After my biopsy, several months passed when I thought things might be better, but then I sustained several more rib fractures from very minor traumas. I was getting frustrated. I didn't see any progress in the investigation and now I was breaking again. We didn't seem to be any closer to finding answers to why I had osteoporosis than we were at the beginning. With each visit to UConn there was just a repeat of all the lab tests that had already be done...nothing new and no focus on what lead to follow next. In fact, there just didn't seem to be any leads at all. The only thing that was happening was just a reiteration that I needed to take a bisphosphonate medication which I did not want to do.

With my greater understanding of osteoporosis and my closer look at the lab work (especially those results that were just outside of the normal reference range), I noticed some interesting connections. The "normal" comprehensive metabolic profile (CMP) for example, showed an elevated level of bilirubin, a breakdown product of red blood cells.

My hunch was that each of my symptoms and the "slightly off" lab tests could have some significance. Each of these might hold clues to understanding the "whole" of me, or at least to the source of my severe bone loss. I felt that implicate* within each symptom, within each slightly-off lab test, there could be some view of the whole answer. Like cells that each hold the same DNA map of the complete organism within them, my symptoms had implicate within them the wholeness of my body's dysfunction. In other words, the biology of each symptom was part of the biology of the disease, which was part of the biology of my whole body's functioning. Each symptom was significant to some extent or another. But like DNA, which is nothing without the cell that cradles it, each symptom and slightly off lab test by itself had no meaning. Even the low bone density (bone quantity) meant little without a vision of the whole structure: what my risks for fractures were, what my bone quality was, what my muscle strength was, and how my organs were functioning. Everything had to be, or at least should be, looked at together.

In addition to the high calcium in my urine and the elevated N-telopeptide indicating a high rate of bone loss, I was now aware of this elevated level of bilirubin in my blood. Could this have meaning? When I thought back to the first weeks after my diagnosis, I now remembered that the endocrinologist had said that I had a mild disorder called Gilbert's Syndrome. In retrospect I saw that he was referring to this elevated bilirubin. But I also remembered that he said it didn't have any bearing on my osteoporosis and we had both quickly dismissed it.

Now, a year later, the elevated bilirubin** and my renewed interest in a possible malabsorption issue prompted me to run some lab tests on my own. One of these tests was for fatty acids and the results were startling. I was extremely low in polyunsaturated fatty acids. I didn't understand it, how could I be deficient in these? My diet included oils such as corn and safflower; I ate peanuts and fish and lots of other foods that contain high amounts of essential fatty acids. They were in my diet...but maybe I wasn't absorbing them? The endocrinologist said there was no connection in this either. But I started to think that maybe the fatty acid deficiency was somehow keeping the inflammation going on in my hip. After-all the hip was still hurting, a year now since the hip pain first began and since I had initially been diagnosed with osteoporosis.

Could the low blood polyunsaturated fatty acids and the Gilbert's Syndrome have something to do with the lingering hip pain—or the osteoporosis—or both! Maybe, I was beginning to see what could be the head of a faint trail. All of a sudden it felt as though I had stepped into nature's complex biochemical laboratory where life's continual transformations are fueled and formed. I began to understand chains of biochemical interactions that I never knew existed, and these chains, like strands in a spider web, were being woven by all the biochemical influences of every organ system in the body. The biochemical trails through this web were confusing and seemed infinite.

In an effort to uncover more strands to this yet completed web, I began to think back to the days in high school and college where I had so much abdominal pain after runs that I had to curl up on the floor and wait for the pain to go away. And then I remembered that this pain, although not as frequent or intense, but there none-the-less, sometimes occurred into my 30s...and, into my 40s. Not all the time, but just after hard runs I would sometimes have intense abdominal pains. It had actually just become part of me and I really didn't think about it any more. But now, reading about Gilbert's—nausea, abdominal pain, weakness—especially after the stress of intense exercise and dehydration...well, now things were starting to make sense. The web was starting to take shape.


                              There are things we can only learn about an organism by taking
                              it apart—but to understand that organism we must fully engage
                              with it as a dynamic, interconnected whole. It is no wonder that
                              different parts of the body—the skin, joints, spine, organs—may
                              all be affected by a disease process even when they have no 
                              obvious or direct physical, chemical, or neurological 
                              connection with each other or the process itself.



* "Implicate" (order) is a term developed by David Bohm, a theoretical physicist, who developed a mathematical and physical theory that explored the concept that everything is connected.

DX Severe Osteoporosis: Part VII -- In Search of the Whole Skeleton



This is Part VII of a multi-part essay about my own personal experience with osteoporosis. I will be taking you through the diagnostic and treatment phases of my care in hopes that it provides you a better understanding of osteoporosis in general, and pearls that you can use to better your own bone health. 


The universe is made up of individual particles that "flow within a continuous energy field encompassing a wholeness much greater than the thought processes which attempt to break the particles from their sea of wholeness."
                                                                                 David Bohm


When I first opened the door into the world of osteoporosis research, it was like walking into an anatomy classroom filled with lots of skeletons. Half of them were broken, missing parts and scattered about, and there was no teacher, just a huge pile of books dumped in a corner. About the only thing I knew was that you were supposed to take calcium supplements and eat lots of dairy. But
it didn't take long, the first book or two on the pile, to make me see that popular ideas about osteoporosis were far from accurate. I had a long way to go and I knew it.

Conventional Western medicine looks for certain signs and symptoms in a patient to match with what are considered the characteristic signs and symptoms of a particular disease entity. The doctor can't consider every physical manifestation that could be a clue to what is really going on because there just isn't time. Where do they draw the line? What physical, mental, or emotional conditions in a patient are significant, and which are not? Western medicine tends to select a small number of symptoms to consider. For each general complaint--headache, back pain, insomnia--there is a brief checklist of questions and a list of diseases to match with the symptoms. In my case, the initial list at the endocrinologist's office was twenty in length. The doctor's objective was not to discover my individual pattern, but to figure out which of a few disease-categories my bones might be dropped into. Having a specific diagnosis, even if it is just called "idiopathic" (meaning "we don't have a clue as to what the cause is...") or "primary," gives us the satisfaction of labeling--satisfaction that the ills are now neatly categorized, ready to be boxed and shipped out for treatment. To categorize is simply a way to feel in control.

The problem is that once we diagnose, it's easy to stop thinking, stop observing. We stop looking for other answers, other possibilities and connections. The pressure is off; the diagnosis is there. But are we really under control...? With a diagnosis, the physician has a ticket to enter the medical superhighway with its trailer-loads of information, and thousands of other physicians and researchers traveling in the same direction. The superhighway feels safe, it's familiar and well marked; but there's lots of country that it passes right by.

I'm not saying we shouldn't diagnose. But there are shortcomings in our way of doing it. Other healing practices approach the analysis of symptoms quite differently. In traditional acupuncture, as in my own chiropractic practice, listening to the patient is extremely important. The acupuncturist relies on the patient's description of the problem that brought them in and on observing the patient--noticing how they move, how they hold themselves, the feel of their skin, their smell, their affect, their energy, even the tone of their voice. As the patient describes symptoms, they are encouraged to mention anything that strikes them as characteristic of their normal pattern, and everything they associate with their current problem.

I didn't feel we were ready to label my loss of bone density with a diagnosis yet. I had no idea what the cause of the bone loss was, but I did know that there was an imbalance spurred by something... somewhere. One of the first tests the Dr. from UConn and I had ordered was the bone resorption marker N-telopeptide (NTX) and the results had come back abnormally high. A reading of 123 nmol/BCE/mmol creatinine with a reference range of 4 to 64* showed that I was loosing bone rapidly. What could cause the osteoclasts, the cells that break down bone, to be so aggressive? Was it diet, stress, over-training, or was it hormonal? Was it toxicity from chemicals or heavy metals? After all, the bone biopsy had shown that strange "zebra striping" appearance that the pathologist had said looked similar to cases of heavy metal toxicity that he had observed before. My biopsy slides hadn't stained positive for iron, and blood and hair analysis' didn't show heavy metals...but tests can be wrong. Or, could it be that my kidneys or my intestinal tract were not functioning properly. I felt TOTALLY fine...I did not FEEL sick. How could my bones be crumbling? How could they be loosing so much density so rapidly and I not feel ANYTHING? Had my genetic makeup just written it that way?

The possibilities seemed endless. The endocrinologists wanted to stick my symptoms in the box labeled "idiopathic" with alendronate as the treatment of choice. But I didn't understand. What did they expect me to do?...take a bisphosphonate drug for the next 45 years? I was only 46 years old, and I might live to be 90 (give or take a few). That just seemed ludicrous!

I wanted a doctor who could look at me as a whole, look at both my inner and outer self as one, not just a case of low bone density. It seemed that an acupuncturist trained in the Chinese healing tradition would be a good person to start with. When I asked the acupuncturist what she thought after her initial examination, she said that of the five elements that make up the body--water, wood, fire, earth, and metal--my constitution type was "fire" and that my smell was that of being "scorched." I wasn't quite sure what to make of this information, I didn't know if it was significant in terms of my efforts to track down the cause of my disease and to make a treatment plan, but I added this information to what I had already found out. At this point in the process, it was just another clue as to how the different systems of my body were working...or, more accurately, not working.


          "The whole may actually organize the parts."
                                                                  David Bohm


* With almost 20 years now of observing the bone resorption markers of hundreds of patients, it is my opinion that this reference range is totally useless. A better reference range for NTX (urine) would be 20 to 45. If a person's NTX gets below 20, osteoclastic activity is probably too low to keep bone quality in the healthy range with minimal microfracture accumulation. If NTX gets over 45 then we run the risk of excess bone resorption and a net loss of bone density.

DX Severe Osteoporosis: Part I -- The Day That Changed My Life Forever



"Glimmering on the edge of death, sweeping in to overwhelm us, is the larger sense of who we are."

   Paul Rezendes
   author of The Wild Within


This is Part I of a multi-part essay telling you about my own personal experience with osteoporosis. I'll try not to be too windy but I will take you through some of the diagnostic and treatment phases of my care. I will offer LOTS of information to help you gain a better understanding of osteoporosis in general, and hopefully even some specifics into your own bone health. 


Part I :  The Day that Changed My Life Forever


I remember the day like it was yesterday...

The doctor put the x-ray up on the view-box...the bones were not white: they were gray--like ashes.

The x-ray of my pelvis didn't light up with the brightness of hard, opaque tissue characteristic of healthy bone. It was dull, and the light that filtered through it, drained the room of substance. There had been barely enough room for an exam table and an old chair, and now it felt claustrophobic. I stood wedged between the two orthopedic surgeons, faces pale and gray in the dim, florescent, hospital light as we stared at the film showing the first hard evidence that something was seriously wrong. "The hip joint itself looks good," the senior orthopedist said, "but the bone looks rare--not much density."

It had been the pain that finally forced me to the doctor's office; the pain that had stopped my running. As an athlete who had trained intensely for over 25 years, running road races, and competing in the sports of modern pentathlon and triathlon, I was used to discomfort and nagging injuries. But this time the pain persisted in a way it never had before. It was in my hip, and at first I thought it was just another over-use injury from running.

But the severity of this injury was more than I could figure out myself...I needed some help.

One look at the x-ray showed an obvious lack of overall bone density. Where there should have been the whiteness of bone, there were the dark grays typical of softer, less-dense tissues. Later an MRI, bone scan, and two bone density exams revealed capsular synovitis with micro-fracturing of the femoral head, and severe osteoporosis of the spine and both hips. Like a ton of bricks, I was totally floored as the bone density technician unprofessionally blurted out, "you have worse bone density than a 100-year-old woman!"

How could I have osteoporosis? I was a 46-year-old man, I had been active all my life, and I had always tried to live a healthy life-style. It seemed to me that nothing I had done had invited this disease, and that I had done a lot that should have prevented it. But here it was. It was too late to shut the door in its face. It had already moved in and was making itself at home. Now I had to figure out how to live with it, how to limit the damage, and how to stop it if I could. And I had to figure it out fast--before it ate away my bones.

Bone Density Loss is Associated with Blood Cell Counts


For over 10 years now, I have been using laboratory biomarkers as therapeutic targets to lower fracture risk for people with osteoporosis. As I explain in my book, The Whole-Body Approach to Osteoporosis, a snapshot of your health record, including results from your bone density (DXA) examinations and special laboratory tests are useful in diagnosing the cause(s) of bone loss and ruling out other disease processes. Some of these tests, can then be repeated to help monitor effectiveness of treatment. Any abnormal test results provide therapeutic targets for improvement. On subsequent testing, positive changes will indicate that the therapies you and your doctor have initiated are making an impact - and that your health, and that of your bones, is improving.

Convincing others to treat osteoporosis using a whole-body approach can be difficult at times, however. One example: 
About five years ago, I was out on a bike ride and came upon an acquaintance, Dr. R, a medical doctor at the local university. I slowed down and rode with him for a while since I had done a hard workout the day before and this was an "easy" ride day. We got on to what I was doing in my practice and I explained my approach in detail. As an allopathic physician with no experience in functional medicine or nutrition, Dr. R just COULD NOT accept what I was saying. When I explained that I regularly see lab tests change due to diet and nutritional intervention he just kept saying..."no you didn't, there is NO way you can change lab results with just nutrition." Dr. R just could not accept these concepts that were so foreign to his allopathic training.

Despite some continued naysayers, I'm buoyed by ongoing research exploring more integrated approaches - addressing not just symptoms, but the real causes of illness. Such an article (1) appeared in the February 2017 Journal of Bone and Mineral Research. Valderrabano et al. takes an expanded look at some of the blood biomarkers that we can look at when evaluating patients with osteoporosis. Instead of simply relying on bone density exams (DXAs) to determine efficacy of treatment, it is possible to look at changes in laboratory test results as surrogate indicators of improved bone health.

Clinical and molecular research shows us that what goes on in a person's bone marrow strongly
affects his or her bone quantity and quality. By observing a person's changes in red and white blood cell counts over time we can see how this correlates to their improving or loss of bone density. [In my practice, two of the markers I use with almost every person with osteoporosis are the red blood cell and the lymphocyte counts.] Oxygen carrying red blood cells are often low because the cells that form them (hematopoietic stem cells) are being crowded out by a buildup of bone marrow fat. Chronic systemic inflammation contributes to this build-up of marrow fat. A decline in lymphocytes (the white blood cells responsible for the adaptive immune response) and a rise in neutrophil counts, are also seen in people with osteoporosis. The reason is the same, chronic inflammation.

What was particularly important about this research by Valderrabano et al. was their insight into the association of these biomarkers not just to bone density but to the "rate" of bone loss. Anemia (low red blood cell count) plus low lymphocytes and high neutrophils can be indicators of higher bone loss rates. By addressing factors to help reduce systemic inflammation, we can see early changes in these surrogate biomarkers (and others) of bone health. This is so much more efficient than waiting two years for the next DXA scan.

When I meet with a person in my office in Massachusetts or I work with someone from another state or country via a telephone consult, my method is the same; gather as much information as possible including laboratory tests and identify "therapeutic targets" to monitor and guide therapy. The focus of treatment for individuals with bone loss should be to reduce fracture risk. This is most effectively achieved by taking a comprehensive approach that includes diet and lifestyle changes, exercise, nutritional supplements, and, when necessary, pharmaceutical intervention. Using this personalized method, patients can be helped to find their own individual path to the management of osteoporosis.

Early Detection and Intervention are Crucial to Stop the Progression of Bone Loss - How Biomarkers Can be Used to Improve Treatment of Osteoporosis

As you know from my book The Whole-Body Approach to Osteoporosis,(1) I am a strong advocate for working closely with your health care provider and using specific laboratory tests to gather critical information about your bone health.

Both men and women begin to lose a small amount of bone mineral density in their mid-thirties. A “healthy” person may lose 0.7% to 1.0% per year after they reach their 40s but this loss is slow and typically has a minimal detrimental effect on their over-all health longevity, especially if they had normal bone accrual as a young adult. But for women, the sharp loss of estrogen at menopause can precipitate a dramatic loss of bone density, up to 3 or 4% per year. A rapid decline in bone mineral density leads to unwanted changes within the microarchictecture of bone, such as cortical thinning and a loss of trabeculae – the microscopic support beams within bone. These changes cause a loss in bone quality. Together, when both bone quantity and quality are lost, there is a sharp decline in bone strength and an increased risk for fractures. Identifying women at greater risk for developing osteoporosis, and especially those who are loosing bone rapidly during transmenopause,* is of key importance. The earlier the detection the better!

When bone densitometry (a DXA exam) is used to determine bone loss, the doctor must compare two consecutive exams over a two-year period to assess the speed in which a person is loosing bone. The larger the loss in bone density, the more rapid is the bone loss and the greater is their risk of breaking a bone. Having to wait two years before identifying those at greater risk can, and often does, result in catastrophic results such as sustaining a hip fracture or spinal compression fracture. Once bone is lost it is very difficult to regain, placing these women at a much higher risk for fracture. With earlier
identification of those at high risk for rapid-bone loss…by eliminating this 2-year period of time…we can intervene with appropriate therapy and reduce the incidence of subsequent fractures.

The GOOD NEWS: Natural therapeutic methods to improve skeletal health works! Changing a person’s diet, taking quality supplements such as the OsteoNaturals line and engaging in bone-healthy exercise work to improve skeletal health by “gently nudging” bone cells into a new and healthier course of being. When working with nutrition, we aren’t just sprinkling more calcium into bones, we are changing the "habits" of cell metabolism. While we can't alter our genetic code - our DNA, we can improve the way a person's genes "express" themselves - the epigenetics of cells. It is through changes in a person's epigenetics that we can put a stop to rapid bone loss and move out of the "high risk for rapid-bone loss" osteoporosis category.

The “NOT SO GOOD NEWS”: Natural therapeutic methods to change skeletal health can take time to “engage”. If a person has had a poor diet for the past 20 years, is in a nutritionally sub-optimal state, and has low-level chronic systemic inflammation, simply improving his or her diet will NOT result in instant success. The sooner we can identify the heightened level of bone cell activity, the quicker we can start “encouraging” bone destroying cells to calm down and reduce their excessive level of bone resorption. Think of osteoclasts (the cells that break down bone) as a gang of wild maniacs on the loose. If you just tell them to stop their wild behavior they probably won’t just “normalize”….on the other hand, put them into a quality therapeutic counseling program, change their eating habits and destructive lifestyle habits and, over a period of years, they may be able to re-enter society as constructive members. The earlier a person is tapped into therapy, the better the results. Changing the way cells “behave” can take several years, several generations of cellular division, even after being immersed into a new, healthier environment.

Back to the GOOD NEWS: With the science of current biomarkers constantly improving and new, even more sophisticated biomarkers being developed, we have come a long way in our understanding of osteoporosis and ways to treat it effectively. Most recently, in a study published in the Journal of Bone and Mineral Research,(2) Shieh, et al. assessed the clinical utility of measuring N-telopeptide (a bone resorption laboratory marker) during the menopause transition as a way of identifying women at high risk for developing osteoporosis. The study included 604 women. The authors concluded that higher levels of N-telopeptide during the early postmenopausal period were most strongly associated with a higher rate of bone loss during transmenopause. This correlation, elevations in N-telopeptide to the rate of bone loss, was most pronounced in the lumbar spine but also in the hip. More studies like this are needed to ensure individuals at highest risk for rapid bone loss are identified as quickly as possible.

I have been using biomarkers such as N-telopeptide (and the other bone resorption markers C-TX and DPD) for over fifteen years to assess and monitor patients with bone loss. I have seen the benefits of early detection of those at great risk of developing osteoporosis and those who have rapid bone loss and thus even a higher risk for fracture. Please help pass the word to everyone you know – especially women approaching transmenopause – about the importance of specific laboratory tests to gather critical information about their bone health. Armed with this information, they can work with their health care provider to customize a plan to address the underlying causes of their bone loss, ultimately enabling them to improve bone health, reduce the risk of fracture, and enjoy a more active lifestyle.

* Transmenopause or menopause transition refers to the period of greatest estrogen loss. Rapid bone loss often begins 1 year prior to a woman's final menstrual period and lasts for 2 to 3 (or more) years after their last period. After this 3 to 5 year (up to 10 years in some cases) period, the rapidity of bone loss normalizes to prior menopause levels.

Osteoporosis: Bone Mineral Density (DXA) Exam vs Risk Factors

Clinical risk factors* for osteopenia and osteoporosis include:

   - Loss of height
   - Low body weight
   - Advanced age
   - Late age at menarche
   - Menopausal
   - Time since menopause
   - Smoking
   - Calcium intake
   - Alcohol intake
   - Medications
   - Inflammatory conditions
   - Prior fragility fracture

But: Risk factor assessment is NOT a substitute for having a bone mineral density examination (DXA). Research shows that 50% of patients with osteoporosis do not have risk factors and 50% of patients with risk factors do not have osteoporosis as per a DXA exam** (T score of -2.5 or worse).

So: Make sure you get a bone density examination (DXA)! Please do not rely on risk factors because they DO NOT predict your chances of having osteoporosis.

High Iron Levels Associated With Accelerated Bone Loss and Fracture Risk

Iron is an essential nutrient and one that is vital for the oxygen-carrying capacity of red blood cells. It is not only important for blood formation, but it is also necessary for optimal bone health. Iron helps convert vitamin D into its active form and therefore is involved in calcium absorption. Iron is also important for normal osteoblastic activity and the formation of strong collagen fibers, the foundation of bone.

Low hemoglobin and iron-deficiency anemia can result from inadequate iron intake; poor absorption due to celiac disease and other GI disorders; or chronic bleeding from excessive menses, ulcers, bleeding hemorrhoids, or cancer. Without iron, or even in low iron anemic states, bone mineral density suffers and fracture risk increases.

On the other end of the spectrum, iron overload can be just as detrimental to a person's health. The two most common causes of iron overload are excessive iron intake (usually from over-supplementing) and hemochromotosis (a hereditary condition where the body absorbs too much iron). Excess iron can deposit within the tissues and organs of the body leading to liver disease, diabetes, heart disease, arthritis, and other maladies. It is also toxic to bone health.

We have known for years that excessive iron loads can have damaging effects to the bone metabolism of animals. But there were no clinical studies to show this effect in humans. Now, for the first time, we have clinical evidence that excessive iron levels can reduce bone density and bone strength in women. In a study by Kim et al. (2013) published in Osteoporosis International, women over the age of 45 with elevated serum ferritin (a blood test for iron levels) were associated with lower bone mineral density and greater risk for fracture. While iron is important for osteoblast function, excessive amounts can be toxic to osteoblasts, reducing their ability to form bone.

It is not unusual for me to see patients with osteoporosis who are consuming excessive amounts of iron. Red meat, liver, fortified cereals, and molasses are all sources high in iron. Take this into consideration if your supplements include iron. Also, while menstruating women may need to supplement with iron to avoid becoming anemic, most postmenopausal women should avoid iron-containing vitamin/mineral supplements.

To avoid inadvertently ingesting too little or too much iron, make sure you are reading labels.

C-Reactive Protein: A Measure Of Oxidative Stress

Your body constantly reacts with oxygen as you breathe and your cells produce energy. As a consequence of this activity, highly reactive molecules are produced within our cells known as free radicals. If your body is unable to stop the spiraling free radical chain reaction (a molecule stealing an electron from another molecule, causing that molecule to steal an electron from another molecule, causing that molecule to steal an electron, etc...) this can cause oxidative damage to proteins, membranes and genes.

Bombardment of cells by free radicals.
When oxidation is excessive and the body is unable to neutralize high levels of free radicals with enough antioxidants, we refer to this as oxidative stress. The deeper the body goes into oxidative stress the more extensive will be the cellular damage that will then trigger an inflammatory response. Free radical damage, oxidative stress and systemic inflammation are all implicated in a number of chronic degenerative disease states and premature aging.

If oxidative stress continues for days, weeks or months, the body can go into a condition called chronic systemic low-grade inflammation. This type of inflammation can stimulate aggressive osteoclastic bone resorption and lead to osteoporosis.

Unfortunately, there is no one test that will tell us if a person has this type of inflammation. But there are tests for general inflammation and others for oxidative stress which, when reviewed in conjunction with the person's signs and symptoms, can give us a good indication of whether that individual has chronic systemic inflammation.

A recent paper by Park et al. in Clinical Endocrinolgy shows that C-reactive protein (CRP), a protein in the blood that rises in response to inflammation, is also a measurement of oxidative stress. The study involved 1821 nondiabetic postmenopausal women with elevated CRP (≤ 10 mg/l) levels. The researchers used an oxidized low-density lipoprotein, a known marker of oxidative stress, to compare with CRP. The authors concluded that CRP is strongly associated with oxidative stress.

Oxidative stress and its impacts can be alleviated with early detection. Having lab markers such as C-reactive protein to provide important clues to the causes of bone loss is of great benefit to a clinician designing a diet/nutrition therapeutic protocol for chronic disease conditions such as osteoporosis.

Jumping Power: A Better Test For Sarcopenia Than Muscle Strength

In a study from the Department of Health and Exercise Science at the University of Oklahoma, Singh et al. examined the relationship between jumping power, muscle strength and sarcopenia (the loss of muscle mass seen with aging and illness). Sarcopenia is often seen with osteoporosis and leads to weakness with an increased risk for falls and fractures.

This study is fascinating because it showed that individuals with
sarcopenia had significantly lower jumping power but not necessarily lower muscle strength when compared to individuals without sarcopenia. "Based on our findings, JPow [jumping power] may be useful for sarcopenia screening in the middle-aged and older adults; however, more research is needed to determine the utility of this method in clinical populations." [No...their method did not include having men and women 55 to 75 years of age jump over cows.]
