Positive Ama M2, all blood work for liver gallbladder normal, suspected other autoimmune disease

[Elineea]

Hello everyone. I did some autoimmune tests, AMA M2 was found positive.Have been to doctors rheumatologist and gastro, did all liver blood tests in a 2 months period, all were normal, .Bilirubin, alkaline phosphatase, all of them were ok. I do not understand, the doctor said it can be a cross-reaction for other autoimmune disorder.Indeed i have signs of other disease, joint pain and some other issues, also thyroid issues.So I don't understand.And another doctor said to repeat and have a quantitative blood test of AMA m2, because if it was with other antibodies and it was just positive but maybe 2 points elevated than normal or something like that, it is not accurate as a blood test.So it was not like- from 0 to 160. It was. just positive.Can someone help me please?

Hi Elineea

I cannot answer your question but I notice that no one has dropped in to say hello. Welcome to the group.

It would seem that once we have one auto immune disorder there is a strong chance that another will come along.

It may be worth sending an email to the PBC Foundation or if you are in the UK telephone them as they have a help line.

I think a hepatologist is better placed than a gastrologist to give us the answers we need, is there one in your area?

I am sorry not to be of more help but hopefully someone will come along soon who can give you a better understanding from their experience.

best wishes

Hi Eileenea, what 'other' auto immune issue do you have? for your thyroid issue do you have hoshimoto or hypothyroidism or thyroiditis?

I am in a similar situation as you. My doctor has not formally diagnose me with PBC yet. Just monitoring by taking blood test every 3 month.

Not much of help but at least you know you are not alone. Let me know what your doctor say.

Thanks,

Hello. They are not sure what other autoimmune disease

You also had positivie Ama m2? You did a positive/negative test or a quantitative one like 1:150 ?

My gastro said that if all liver blood work is ok It must have been a wrong test. He wanted me to do a quantitative one.

I will take that this month.

Elineea, sorry about the delayed response. I was tested positive on AMA M2 3 years ago. It was 23.0 and now 30.1 My liver enzyme and bilirubin fluctuates between high normal or slightly elevated. No medicine given for it yet.

I never done a quantitative test. Not sure what it it.

I would appreciate if you let me know what's your result.

Best wishes,

Jane
