Fibromyalgia and, perhaps, What Happened to the Missing Females with Autism
When you look at all the proposed drugs and supplements, there is a 90% overlap between the two conditions, even things like low dose naltrexone and flavonoids, like quercetin, crop up.
As we have seen earlier in this blog, autism is a disease related to the auto-immune system and inflammatory pathways. There are many other diseases with similar origins, one example being arthritis. Fibromyalgia tends to get lumped together with arthritis. Families with autism present tend to have higher levels of arthritis and there are even some overlapping therapies, such as vagus nerve stimulation.
Fibromyalgia caught my attention, because it seems to be uncannily closely related to autism, but there are some distinct differences. Classic “full-on” fibromyalgia is a disease about pain, whereas in autism people tend to have a high pain threshold. Nonetheless, if you Google “Fibromyalgia with Autism” you will find no shortage of people suffering from both and pondering a connection.
Comorbidities are interesting, because they can indicate possible new therapies. The people researching fibromyalgia are not generally the same people as the autism researchers. The underlying pathologies though are very likely overlapping, even though neither is fully understood.
Fibromyalgia is neither degenerative nor curable, but it is treatable.Here is a link to an article by a US doctor who came to the same conclusion. (The article itself is not great)
Symptoms of Fibromyalgia
We can split these into two categories, pain-related and pain-unrelated. In the case of autism we should look at pain-unrelated, but in the case of relatives we should look at both. You will probably be able to diagnose a non-autistic family member with symptoms of this syndrome.
Pain-related:-
· Widespread muscle pain and joint pain, the effects of these symptoms varies from person to person and from day to day. Many people have flare-ups. There are specific pain areas, and these are shown below:
· Long-term studies suggest that it is not progressive, it does not cause permanent damage to your muscles, bones, joints or organs.
Pain-unrelated:-
This is a long list and typically only some will apply to any one person:-
· Cognitive dysfunction, such as:
o Difficulty following directions when driving
o Losing your train of thought in the middle of a sentence
o Difficulty paying attention
o Memory problems
o Difficulty expressing ideas in words
· Depression, anxiety, irritability, overreaction, anger outbursts, unpredictable mood swings, phobias and personality changes
· Difficulty swallowing
· Headaches
· Restless leg syndrome
· Sensitivity to the cold, and/or having cold hands and feet
· Palpitations
· Chest pain and costochondritis
· Sensitivity to light and noise intolerance.
· Clumsy walking, dropping things
· Hair loss
Fibromyalgia vs autism
There are some other similarities/differences with autism.· It often takes years to get a diagnosis and some doctors do not believe the condition exists
· There is a specialist doctor that should know about it – the Rheumatologist, although Neurologists sometimes get involved
· It is not curable, but it is treatable
· It is usually diagnosed on very subjective measures
· A blood test does now exist in the US - the FM/a test
The firm with the blood test is called, interestingly, “Epigenetics”. If you make a blood test for Fibromyalgia, there is a good chance that the same researchers could develop one for autism. They are measuring the level of pro-inflammatory cytokines.
The test is expensive, about $750. Who knows how accurate the result is; they claim 99%.In the UK, the National Health Service maintains that no test for Fibromyalgia exists.
A Neuro-immuno-endocrine disorder
Evidence exists that fibromyalgia is a neuro-immuno-endocrine disorder. Elevations in substance P, IL-6and IL-8as well as corticotropin-releasing hormonehave been found in the cerebral spinal fluid of fibromyalgia suffering individuals. Increased numbers of mast cellnumbers have been found in skin biopsies of some individuals with fibromyalgia. Theoharides, who I have quoted extensively in early post on mast cells and autism, appears here too:-
Fibromyalgia--new concepts of pathogenesis and treatment.
Abstract
Fibromyalgia (FMS) is a debilitating disorder characterized by chronic diffuse muscle pain, fatigue, sleep disturbance, depression and skin sensitivity. There are no genetic or biochemical markers and patients often present with other comorbid diseases, such as migraines, interstitial cystitis and irritable bowel syndrome. Diagnosis includes the presence of 11/18 trigger points, but many patients with early symptoms might not fit this definition. Pathogenesis is still unknown, but there has been evidence of increased corticotropin-releasing hormone (CRH) and substance P (SP) in the CSF of FMS patients, as well as increased SP, IL-6 and IL-8 in their serum. Increased numbers of activated mast cells were also noted in skin biopsies. The hypothesis is put forward that FMS is a neuro-immunoendocrine disorder where increased release of CRH and SP from neurons in specific muscle sites triggers local mast cells to release proinflammatory and neurosensitizing molecules. There is no curative treatment although low doses of tricyclic antidepressants and the serotonin-3 receptor antagonist tropisetron, are helpful. Recent nutraceutical formulations containing the natural anti-inflammatory and mast cell inhibitory flavonoid quercetin hold promise since they can be used together with other treatment modalities.
Treatment
Classic treatment involves tricyclic antidepressants, which are actually very closely related to the early antihistamine drugs. Even though low brain serotonin is a feature of the disease, counter-intuitively, it has been found that serotonin-3 receptor antagonists are effective; this is the opposite of what was expected. Tropisetron is a favoured antagonist, but there are several others. Tropisetron is also a α7-nicotinic receptor agonist, which you may recall, I highlighted as interesting in posts on the cholinergic system and autism.
This blog is about autism, so let us go back to a previous paper I looked at.
In that paper tropisetron is put forward as a potential autism treatment.
10.1.2 ᾳ7 nAChRs
It is possible to use ᾳ7 nAChR agonists to treat neuroinflammation in ASD. There is strong evidence that activation of the ᾳ7 nAChR expressed on monocytes and macrophage, by inhibiting NF-kappaB nuclear translocation, suppresses cytokine release by them, and that this cholinergic anti-inflammatory pathway that provides a bidirectional link between the nervous and immune system, inhibits the innate immune response. Hence, a reasonable case can be made for the use of ᾳ7 nAChR agonists to treat neuroinflammation in ASD.
A second candidate drug, Tropisetron is a partial agonist of the ᾳ7 nAChR. Auditory sensory gating P50 deficits are correlated with neuropsychological deficits in attention, one of the principal cognitive disturbances in schizophrenia. In a clinical trial with 33 schizophrenic patients administration of tropisetron, without placebo, significantly improved auditory sensory gating P50 deficits in non-smoking patients with schizophrenia. In mice, the early postnatal period represents a critical time window essential for brain development. The administration of tropisetron from postnatal days 2-12
(P2-P12) in mice did not induce significant cognitive, schizophrenia-like or emotional alterations in tropisetron-treated animals as compared to controls, when tested in multiple behavioral assays.
It is the non-conventional treatments that overlap with autism, things like GH, IGF-1 and low dose naltrexone etc. The interesting therapies relate to treating the non-pain symptoms. There are many such therapies and some have been used for decades, one or two may be interesting for autism; they may indeed be more effective in autism that in fibromyalgia. There is even an overlap with therapies I am already investigating.
Hi.. Andersen Tawil Syndrome gal here.. almost everyone I have met diagnosed with or suspected to have andersen Tawil Syndrome (potassium ion channelopathy) has been at one time or another been diagnosed with fibromyalgia... and or conversion disorder..
ReplyDeleteA quick google will show you that Periodic Paralysis is one of the most often misdiagnosed as conversion disorder.. Every one of the symptoms listed under fibromyalgia above is a symptom we deal with but perhaps ten fold.. with many starting in our childhood.. Three days on a low carb low sodium high protein diet and almost every one of the symptoms was gone.. (i also supplemented with 3000 milligrams of potassium daily while on this diet and while taking quinapril I was so sure this diagnosis was the correct one for me.that i was will to take the risk of coupling quinapril with high dosage of potassium.. In the five years since my diagnosis my physician concurred and now orders my medications.. Dr Frank Lehman Horn also concurs through sharing of family history and my treatment and results.. Dr Lehman Horn and associates of the university of Ulm in Germany continue to search for unknown mutations for many of us.with an Andersen Tawil like disorder.
Many of us have spent upwards of thirty years carrying this misdiagnosis.. many of us believe many diagnosed with fibromyalgia, conversion disorder crps and even mitochondrial disorder (of unknown etiology) may actually suffer from this disorder..
That being said exercise is a trigger for us and actually causes damage. So perhaps those with fibromyalgia that also do not improve with exercise may be our sisters and brothers..
All very interesting. I came across an interesting American doctor, Jay Goldstein, now retired, who had some very interesting ideas on strange neurological conditions like chronic fatigue syndrome, fibromyalgia etc. Nobody really knows what is behind these conditions. A quick chat with doctors in my family, revealed that if you do not know what is causing the patient's strange "imaginary" shoulder pains, you tell them it is Fibromyalgia and it has no cure.
DeleteWell Goldstein did try and cure it. I just bought his book "Betrayal by the Brain"; many of his drugs are the very same drugs now trialled in Autism (Baclofen, Spironalactone etc)
The problem with diagnosing with fibro instead of the appropriate diagnosis such as Andersen Tawil Syndrome as in my case which can result in sudden cardiac death, many in a given family will continue to die well before there time.. which has happened so many times in my family.. the irony being simple supplementation with potassium and an appropriate diet low in sodium low in carbs plenty of good fats and quality proteins may indeed save your life.. I have been tracking through the symptoms of my disorder along with the facial features that occur with it and have been able to track it back over 2000 years or approximately 70 generations.. the most fascinating thing I have discovered is it follows my royal lines.. and may indeed be a large portion of the maladies that affected the royals of Europe.. if this is the case these disorders are much more common and are often labeled crps fibromyalgia chronic fatigue etc... Everyone in my family has royal dopplegangers and many have more than one.. the habsburg lip and chin is very common in my family Both the retrognathic and prognathic jaws.. A few questions a dr. could ask a patient that seems more complicated are these. Did you fail your physical fitness evaluations in elementery school? Do you ever get muscle twitches or growing pains growing up? Do early deaths occur in your family tree.. what is your ancestry.. Do you feel bad or exhausted after eating a meal in a restaraunt.. sodium is a big trigger for my particular form of periodic paralysis. Sensory overload issues much.. dentist visits cause you anxiety or are very painful because lidocaine or novacaine doesnt work.. If drs. did this and explored Ion channelopathies as a possible diagnosis many of these lazy diagnosis could be done away with. I believe I may have shared with you previously that certain facial features accompany andersen tawil syndrome.. a high forehead small or prognathic lower jaw.. webbed or curvy toes and also clinodactyly crooked pinky.. I didn't realize what I was experiencing was a genetic disorder until I put together my symptoms with the problems my children were dealing with and came up with Dr Michael Segals Article on sensory overload issues and connections with the ion channelopathies.. three days on the proper diet with an extra 2500 mgs of potassium a day I woke up pain free and able to touch the floor for the first time in over 25 years.. Germanicus may not have died from poison he may have died from an attack of hypo or normo kalemic periodic paralysis causing an arrythmia as a result of long qt.. Karen
