Assistance with Potential misdiagnosis.

Hi All,

I was unsure where to turn and you guys are my last hope!

In July 2020 I was diagnosed with MS ( Multiple Sclerosis ) due to having some numbness and tingling in legs and foot and cognitive problems ( forgetful and thinking issues ) and extreme fatigue.

I then had an MRI which revealed lesions on the brain (5 white matter lesions).

Blood test results show my B12 is low/normal but folate low, High Homocysteine levels and Methylmalonic acid levels normal (212) but also Positive for Anti Gastric Parietal cell antibody and negative intrinsic factor antibody.

I have also been having Ectopic beats for a few months now regularily.

Have been told since then that we have Pernicious Anemia in the family and all of my family members have this with similar symptoms.

Could this be Pernicious Anemia and not MS? ( my neurologist constantly says no ) but i feel like everything is far too coincidental... If anyone has any knowledge on this I would really appreciate the help.

Well I have heard of cases of P.A. being mis-diagnosed as MS . It is not all that rare to hear this . The symptoms that you describe are just like I had. I had palpitations for several years , Sometimes I fainted , but still my doctor told me to ignore them . Tingling in my feet eventually turned to numbness . Exhaustion , breathlessness , confusion also .set in High homocysteine as well I got a private IFAB test , which was positive. So P.A. was proven .

But if you read the posts on this forum , you will know that this test shows up negative in about 50% of P.A. patients . Also you can have a normal B12 level and still have P.A. — The medical profession is so very ignorant on the subject of P.A.

I don’t want to give you false hope , but reading that P.A. is in your family , it’s quite possible that you have P.A. B12 injections would help you enormously if this is so So talk your doctor into you having them . First loading doses of 6 over 2 weeks and then every other day until no improvement . B12 is harmless even if you do have MS . You cannot overdose on it . Also very cheap ( I have to self-inject as I need more than G.P. will allow me . Cost is about £1.50 for an injection -everything included .) Very best wishes .

Hi, thank you so much for your reply and advise it means a lot!

My neurologist is kinda making me feel like I'm crazy but I just have a HUGE feeling it's all PA and not MS but no one seems to understand so on here I thought everyone might!

I am going to try and get them to get me some injections some how!

in reply to smileysammi

Hi smileysammi,

Having had multiple tests like you, M.S. was ruled out

In my case, as I only had demyelination in the legs,

But my Niece unfortunately has M.S. along with P.A. as confirmed when the MRI scan showed lesions.

She has to have regular B12 Injections.

You say your B12 is low/normal and folate low, you should be treated correctly for both.

Please consider writing to your GP. If you have PA in the family all the more reason why you should have injections.

There is a lot of information which sleepybunny has put onto many posts, regarding getting the right treatment and writing letters.

I am really surprised that your neurologist hasen't put injections/folate implementation request to you gp.

IF you do not convince your gp, you could ask for a second opinion, write to the neurologist, do all that you or family can .

Hi Sallyannl,

Thanks so much - yes I think perhaps I should write a letter as emailing and calling seems to not be going well.

I was prescribed b12 and folate tablets but the problem is I feel like I am not absorbing any of it and should look into injections I think...

in reply to smileysammi

You have P.A. you are not going to absorb tablets,You need injections.

When writing to your G.P. keep copies,

Hi,

I hope you find support and useful info here.

Do you mind me asking which country you are in?

The reason I am asking is that the way B12 deficiency is treated varies from country to country and also the type of b12 commonly used can vary.

I'm in UK so some info I post maybe specific to UK.

I am not medically trained.

PAS (Pernicious Anaemia Society)

Based in Wales, UK. Has some members in other countries.

There is a helpline number that PAS members can ring.

I would get a second opinion.I had 2 brain Mri scans.

Ms was ruled out.

I however had white lrsions and t2 flares??

A few more anomalies that terrified me but apparently can be seen at 'my age !

I have see 3 neurologists with different theories looking at my scans

They said B12 definitely can mimic Ms .

So if you are in any doubt get another opinion from a different neurologist.

I echo what gers have said about getting treated with B12 ax symptoms k realise can overlap bug very familiar.

May add more later to this reply.

On NICE website

It states ...do not diagnose MS on the basis of MRI findings alone.

Also... do not treat tiredness in MS with b12 injections

I cant go any further on website

It's just a lot... they contradict themselves and are not even open to the idea of exploring... and as he said based on my MRI. But honestly I have been having thinking problems and fatigue since i was around 16 and I doubt MS would develop from that stage...

in reply to smileysammi

I guess your best bet is to get b12 injections, that way you will benefit regardless. Maybe your g.p. will be open to giving you at least one (cant do any harm) that way you would be confident in knowing you dont get a reaction and confidently go forward in injecting yourself.

(Proof is in the pudding as they say !)

NICE guidelines for MS (UK document)

nice.org.uk/guidance/cg186

It could be both.

B12 deficiency affects the myelin and leaves nerve ending exposed. Especially the smaller fibres and sensory nerves.

MS does the same but is not reversible in the way b12 has the potential to be.

A recent report, however, showed MS is caused by a virus.

technologynetworks.com/immu...

Neurologists know very little about B12. And they know very little about MS, since they thought it was an autoimmune condition but evidence shows it to be caused by a virus.

Push push push your GP for blood tests and injections. Your neurologist has already moved onto the next patient.

Thanks Firefly, I am trying... If not I have a new plan to try and take B12 sublingually and see if this makes a difference.

Hello! Just because you have low normal B 12 levels it does not mean you do not have PA. That was the reason so many doctors missed my diagnosis. I had a low normal B12 result, in the 300’s then 400’s after taking B12 pills but my neurological symptoms were extreme tingling burning etc, To the point of actually barely being able to walk. Since B12 deficiency affects everyone differently and your symptoms are common to PA I would definitely not rule it out. Best thing if the doctor does not diagnose you with PA is to try and self inject B12. You cannot overdose on the B12. I am blessed to have a doctor that works with me, I take 2x B12 1000ml a day. Most people don’t need so much. Also I’m in the USA. I hope you really find the treatment you need. It’s so hard to be sick and not being treated properly. Hugs to you!

Thank you so much; seriously you have set my mind at ease a little! I just need to be more forceful with the doctor i think!

Positive Anti-gastric parietal cell antibodies WITH low b12 deficiency is considered indicative of PA. APC test doesn’t have the same specificity as intrinsic factor testing so I think clinicians look to see low b12 in conjunction with being positive for anti Gastric parietal cells as enough for PA diagnosis, provided that thyroid conditions, diabetes or Addison’s disease are not present (these can be other causes of positive APC results). I’m APC positive and was really b12 deficient and clinicians seem happy to classify this as PA, whilst repeatedly testing as intrinsic factor negative.

Thanks so much for the information! Wish my GP and/or neurologist would feel the same way... maybe I need to go directly to the hematologist.
