Vet Develops Fibromyalgia Blood Test?

Yes there is a reason why there is a Question Mark within the title, Blood Tests for Fibromyalgia have form! (See “Fibromyalgia Blood Test, The Bigger Picture” on 19th April 2003 & “Blood Test for Fibromyalgia Available?” on 12th March 2003)

Here a Vet claims to have developed a blood test that can detect a “fingerprint” caused by Fibromyalgia. It is totally different to the method used in the commercial test by EpicGenetics, Inc. in the USA too. There are a few important highlights that stand out for me. Firstly, is a test group size of only 14 Fibromyalgia Patients, 15 patients with rheumatoid arthritis, and 12 with osteoarthritis. They claim it was 100% accurate on that group, but that is no where near the scale of testing that would deem this as a breakthrough. I don’t know if the advent of social media brings these stories into the public domain far sooner than in the past, but I can’t help but thinking stories like these are very premature. From this group you can quickly see that there was no control that eliminated the variables of Fibromyalgia or Arthritis. This means the test, at present, has no diagnostic value. All this test has achieved is to correctly categorise Arthritis against Fibromyalgia in a group of 41 people where each has either condition. This of course can be done already with different blood tests and potentially with just a physical examination (by an experienced Rheumatologist to detect inflammation in joints and similar problems.) In fact the blood test could just as easily be detecting arthritis instead of Fibromyalgia.

The Vet behind this is Professor Tony Buffington, (DVM, MS, PhD Diplomate ACVN) of Ohio State University and I first saw the articleBlood Test Could Lead to Early Diagnosis of Fibromyalgia” published on the 24th July 2013 on the National Pain Report.com Website.

At this stage I would not even refer to this as either “interesting” or “promising” and I would be very disappointed to see this test being offered commercially any time soon. It seems there is much commercial interest in developing a diagnostic test for Fibromyalgia however we do not seem to be gaining any understanding about the condition or the science behind it. I feel without a leap in our understanding about Fibromyalgia any diagnostic test will just be measuring a coincidence at best and does not show an advance for patients in any way. We already have a diagnostic criteria widely accepted for Fibromyalgia and I would rather see progress in understanding or treatment first.

Fibromyalgia Blood Test, The Bigger Picture

On 11th March I posted about there being a Blood Test available in the USA that claims to diagnose Fibromyalgia. I hope that one of the things that came across in that post was my level of “healthy scepticism” and although I am not medically qualified I could see a few warning signs that the Blood Test might not be all it claims to be. Since I have been able to research this story more (as I am sure many of you have done) I soon found evidence that backed up my scepticism.

The background to this story first appeared in a study titled “Unique immunologic patterns in fibromyalgia” published on BMC Clinical Pathology (A publisher of peer-reviewed Science, Technology and Medicine journals) website by Dr. Bruce Gillis. The study claimed that “the cytokine responses to mitogenic activators of PBMC isolated from patients with FM were significantly lower than those of healthy individuals, implying that cell-mediated immunity is impaired in FM patients. This novel cytokine assay reveals unique and valuable immunologic traits, which, when combined with clinical patterns, can offer a diagnostic methodology in FM.”

So it appears the study suggests that “cytokine” levels could be tested and that this test could offer a method of diagnosing Fibromyalgia. Following this many people expected that this could kick start research into “cytokine” and that it may offer a glimmer of hope for Fibromyalgia patients in years to come. But what happened only a few months later was that a company called EpicGenetics in the United States started to offer a commercially available Diagnostic blood test for Fibromyalgia. The test was called the FM/a® test for a fee of $744.

Now going back it appears as though the author of the Study published by BMC Dr. Bruce Gillis is also the founder of the company EpicGenetics according to this article entitled Questions arise over new diagnostic test for fibromyalgia by Fox News and also shown on a company biography here. So here we have a potential commercial motive here for this study and diagnostic test although it is worth saying that this is common practice and isn’t in itself evidence of something more sinister. This said a diagnostic test for Fibromyalgia could be very profitable for a company given the fact diagnosis is currently one of exclusion in that a patient presenting with symptoms will receive various tests for other medical problems and when they all come back negative a diagnosis of Fibromyalgia is then considered. Also patients diagnosed with Fibromyalgia quickly learn that some people do not believe in the condition itself and with a lack of physically visible symptoms they find their condition hard to prove to anyone, friends, family, employers and even medical professionals alike. So it is no surprise to find that in the first month EpicGenetics took three quarters of a million dollars ($750,000) in payment for tests in their first month giving the lab approximately 1,000 tests to process.

One of the most vocal criticisms comes from Professor Fred Wolfe (Director of National Databank for Rheumatic Disease in the USA) in his blog post entitled “Junk Science – Junk Ethics.” He states that “Cytokine levels are abnormal in many physical and mental conditions” and concludes in saying “that they (EpicGenetics and Dr. Gillis) were trying to fool people into buying the scientifically unproven $744 test.” This criticism has been quoted in several articles written on the Internet and quite frankly plenty of criticism is available if you start looking into the test online. That said people rarely research these things and often assume that if a medical company offers a test it must have had all the appropriate testing needed and that it is backed up with sound medical science.

So it appears as though this test might not be as great as it appears to be. It seems to have come about from a single medical study conducted by the people profiting from the money the test makes and there are many questions about it that remain unanswered. The study fails to address some rather big issues like;

What other conditions display the same result?
What exactly is the mechanism behind these cytokine levels?
As test patients had a diagnosis of Fibromyalgia for over a year how do cytokine levels change in early and late stage patients?
How many independent Studdies should there before a diagnostic test is marketed?
Is there anyone responsible for regulating this area of medicine and diagnostic tests offered by companies to the public?

So I’m afraid it isn’t all its cracked up to be. Personally I would advise against the $744 fee for a very questionable diagnosis and before you do, consult your doctor or specialist first. It is hard to believe a diagnostic test can be offered as a result of a study performed on 201 patients funded by the company payment for a test goes to. It reminds me of the small print on television shampoo adverts when they say “90%” of people loved this shampoo but on the bottom of the screen in very small writing you read “out of 10 people asked.” But the shocking thing is the Shampoo industry may be better regulated.

What do they want? Blood?

Well actually yes! But just to test low serum testosterone and Vitamin D.

So blood is what they got today. It has been requested by my Pain Management Consultant to check pituitary gland function due to the amount of morphine I use. I am due to see the Specialist Pharmacist next week who will review the results with a view to getting me off the morphine. It’s Typical that my shoulder would flare up a week before as that’s the exact thing the morphine was intended for in the first place as it is probably my most serious form of breakthrough pain. It’s only been mismanagement and crazy ideas of treating breakthrough and chronic pain all with morphine that got me dependant in the first place.

My unique problem with Blood Tests

On a side note extreme pain when having blood tests was the first manifestation of the super sensitive over-reaction my body seems to be all about and if you monitor my blog regularly you will know I consider this sensitivity and over-reaction to be the underlying cause of all my problems. Having blood taken is the most painful experience I have ever had, yet I live with chronic pain, have broken bones and suffered various far more serious pain manifestations but nothing compares to a blood test. No person has ever offered me an explanation as to why, medical professionals don’t seem to understand it, realise how significant it is and some may even not believe it. Way into adult life blood tests continued to be just as painful and ten to fifteen minutes afterwards I would go white, then green and pass out, every time without fail and no-one could understand it let alone stop it, I’ve even panicked a GP into thinking he had killed me during one of these episodes. This is how stupid my body seems to be! As a child, well teenager, I explored this problem with a psychologist as it seemed to be the best theory but even he concluded it was not a psychological response but a physical one for unknown reason.

However, with the help of a friendly nurse a few years ago we finally cracked it. I now use EMLA cream (Lidocane) at least an hour before on the skin over the best vein and dress it with a Tegaderm Film dressing. I then have it taken in a private room and I remain in there for about half an hour to ensure no collapsing occurs. When this has been done I feel absolutely no pain! So this is the solution, and although it’s a pain to arrange its worth it as I can now have pain free blood tests, which was probably my number 1 life wish!

I would be very very interested to hear from anyone with a similar pain response to blood tests or indeed the same delayed collapse afterwards. I really do believe it is an example of the mechanism in my body that is behind all my chronic pain issues yet I have never met anyone with the same problem or any medical professionals that understand it. I can’t help thinking I could solve most of my problems if this mechanism could be understood, so if you can help me you MUST let me know!
