Hi, I'm Ian. Sorry for this long post. Just found out today after a 7+ yr journey of trying to figure out what is wrong with me that I have markers for Myositis ok my blood work. I started with very low key fatigue almost 10 years ago, with brain fog calling around 7 years ago (trip to the memory service and all was clear).

After that was diagnosed with Sleep Apnoea, which I'm treated for and hoped this would solve the issues. Nope I use my machine and there is less sleepiness but the fatigue got worse, slowly but surely.

Then I started to experience some mild balance issues with some coordination problems. Still not too bad but my grip got weaker with pain in my forearms.

Checked with a private Neurologist and it was suggested that it might be Carpal Tunnel or Spinal Stenosis. Nope it was neither.

About 3 years ago the gradual muscle fatigue and weakness started, it's not clinical, I can operate but have no stamina and reduced strength.

Got no where with Endocrinology, other than low testosterone, treated and no difference.

Most recently I've developed some Atrophy in my left calf (dominant leg) and fasciculations (tiny muscle twitches).

I walk like an old man, in fact often I'm passed by many silver haired folk.

So it looks like that today, I finally have the start of an answer and it appears I am showing markers for Myositis. As much as I don't want it, it does feel good to see something tangible that might be causing the above and it may also be treatable, possibly.

So my GP has asked Rheumatology for advice and guidance. What should I expect next in terms of getting a diagnosis? I'm East Lancashire.

I'm on the list for Neurology which may still be needed, for some of my symptoms which may not be typical.

Just thought I would say hello and see what you all have to say.

Cheers, Ian.

Hello Eogz

Yes, diagnosis can take for ever! Once clinicians believe myositis is a serious possibility, a typical route is to do a full blood profile for markers (as you have found, there are a host of antibodies that can suggest different variants). You may then get a MRI, but the definitive test is usually a muscle biopsy. Some clinicians seem to favour a relatively modest "punch" biopsy, others a bigger sample. This is done with local anaesthetic but by a surgeon, with proper operating theatre protocols. The results should be pretty definitive, and treatment options will follow this. Two major variations would be PM (polymyositis) and IBM (Inclusion Body Myosistis) The first is an autoimmune inflammatory condition usually treated with steroids and immune suppressants; the latter is not. Both are typified by muscle weakness and fatigue.

If you haven't already, you might want to join The Myositis Community of Great Britain and Ireland on Facebook. It's a very active group - much more so than this - and has 3k members, so there's always someone who will help on there.

Hope that's useful x

Thanks, I've applied to join the group. Many thanks for your reply.

My understanding is that most physician now consider the blood test the 'definitive' test for inflammatory myositis (those caused by auto antibodies, and generally showing muscle inflammation) and that muscle biopsies are only really run when the blood test shows no markers (a rarer case where the blood test can be negative but myositis still present). The normal tests used are an EMG (check electrical signals for both nerves and muscles and minimally invasive), MRi (with contrast to visualize on a large scale the state of the muscles checking for wastage, edema and inflammation), blood test for myositis antibodies and (sometimes) a muscle biopsy. Please note there are other forms of myositis which show similar symptoms but have different causes (for example chemical, which can be caused by steroids, genetic forms, myofibrillar myositis is an example, this can look like the necrotizing form of inflammatory myositis). I know this as I am both positive for anti-SRP immune mediated necrotizing myositis (NAM) and myofibrillar myositis type 4 (MFM4, five genetic defect leading to this are known), both confirmed by the antibody test, MRi, EMG, biopsy and genetic testing (very, very rare combination as they are completely independent of each other and both are rare). My diagnosis was also confirmed by world experts in myositis. I was given a biopsy only because my symptoms are atypical - both proximal and distal muscles impacted (NAM proximal, MFM4 distal, slow moving (NAM is general fast moving, biopsy show signs of both).

Thanks for your reply. Looking at Dermatomyositis it doesn't seem to cover all the symptoms and I do have distal atrophy of the left calf with fasciculations in both calves.

Also some balance and coordination issues (which may in fairness be due to the severity of the fatigue).

I'm hoping an EMG will come about as this will establish to some degree what is happening.

All of this only happened due to the atrophy and fasciculations starting (Jan this year).

So I'm grateful to be getting somewhere, it's been limbo land for the last 7+ years with no specific symptoms and my own self reporting which to a medic (GP) might as well be lies.

I'm not blaming anyone but there isn't much follow in on reports of fatigue and not obvious clinical weakness.

I'm a big strong fella, so it was always going to take time to show weakness.

Thanks again for the info, I'm very much at the start of this new chapter, but so much closer to answers, which is such a relief.

[Eogz in reply to SoonToBe]

Thanks again, that was really helpful.

Is there any skin component? Dermatomyositis normally includes skin involvement (as well as muscle involvement). It would help if you knew exactly which antibodies were detected in the blood test. You can find out a lot of information on these links: understandingmyositis.org/ or myositis.org/ (these are US link but with the larger population much more information is available)

An EMG would be good but bare in mind it is not a definitive test - it can only tell if a nerve or muscle issue is present (it can suggest which form of muscle issues are present but).

[Eogz in reply to SoonToBe]

I had a positive on MI-2 Beta, during the ANA screening along with a whole host of other tests. Creatine Kinase was normal. Some slight elevation in white blood cells and irregularity with red. But nothing to write home about.

It took 6 weeks for the ANA results to come back.

Yes, I don't have rashes or anything like that. It's purely muscular, fatigue etc.

So the GP has asked for advice and guidance from Rheumatology and I have a referral in for Neurology due to some more Neuro symptoms, also the calf atrophy and fasciculations are a worry. An EMG would rule out more worrying conditions like MND (of which there are several types).

I did read that you can have a non dermal version of Dermatomyositis but I'm not fixed that this is the answer.

It's more that it hopefully gets me in a better direction for diagnosis.

Thanks for the links I'll check them out.

Thank you for the understanding myositis link - really helpful - especially link to Dr. Bhai - just the medical approach I was hoping for.

[SoonToBe]

I agree an EMG would isolate whether muscle or nerve related. MI-2 has only been seen in a low percentage of DM case - around 11% of a 357 cases in a paper published in European Journal of Dermatology (Apr 2020). Of these nearly 80% showed some form of skin impact. So it is possible but at a low percentage risk. I maybe you have such but a skin biopsy is better to assess for this in particular. Polymyositis is just as likely as it sounds as if they ran ANA (this checks more for other autoimmune conditions like RA). I'd ask for a myositis panel to be run - that will tell better if you have any of the known myositis antibodies. Low CK does not always indicate that myositis is present (mine has never been above 600). This is a good reference for dermatomyositis so check for the other skin effects other than a rash - myositis.org/about-myositis... PS. My genetic tests took 9 months to come back and my myositis panels (had a few) generally take up to 6 weeks.

I was diagnosed with IBM this April after 12 plus years of symptoms you describe only to be sent for blood tests G.p's beyondpathetic. Long story short I forced a referral to a Geriatric consultant (I knew no other way) I then had Muscle density tests I was then referred to a Neurologist who suggested (I insisted) on having a Muscle Biopsy, as far as I know that is the only definitive way forward to a diagnosis which I had in March to get Diagnoses of IBM in April. Hope this helps. BTW tests were done in Walton Centre Liverpool.

[Eogz in reply to DixieBlue]

Also really helpful thanks very much. As regards the ANA testing it was helpful as it identified an issue.

Which is the furthest I've been in over 5 years.

I'm glad, which sounds really odd to be where I am.

The limbo experience isn't nice and opens you to much gaslighting from the medical and bureaucratic disability (DWP) people.

So either way, I have a distance to go but it's in the right direction.
