Hi Marburg
Sorry for the delay in posting - I am in UK so in a different time zone!
It seems to me that the tests rule out viral things like Hep b or C but could indicate an autoimmune liver disease. In addition you say you have been told you have fatty liver disease.
On fatty liver disease, as your hep has probably explained, the most common type causes some liver function tests to increase but can respond to weight loss etc. In a very very small number of people it is a different type that can lead eventually to cirrhosis and possible transplant. Only a biopsy can tell which it is - so my guess is that is why your hep mentioned a biopsy.
The fact that your liver function test are normal is good. That means there is little or no active inflammation going on. So you should be pleased at that.
The antibody tests suggests there may be an autoimmune process going on in your liver but there is no definitive test for these so diagnosis depends on an experienced hep piecing together lots of different results and symptoms etc to arrive at a diagnosis. Again a biopsy may be suggested as that will provide some of that information. Is your diabetes type 1? Having another autoimmune disease or having a relative with one is another piece of information that feeds into the diagnosis.
There are basically 3 different types of autoimmune liver disease depending on whether the autoimmune process is attacking the liver, the large bile duct or the small bile ducts. The 3 different diseases are autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC). But to complicate matters further there are big overlaps between the diseases and someone with AIH may have some results more common in PBC or PSC and so on. Again that is why an experienced hep is needed to try and unravel it all.
The good news is that they can all be controlled with medication - AIH more so than the others - but there is no reason why any should cause big issues long term.
I confess I have never seen a smooth muscle antibody result expressed like that - normally I have seen it shown as a ratio. When it is shown as a ratio then below 1:20 is normal, above 1:160 is very suggestive of AIH and in between sort of points to AIH but not as strongly. But as your results state it is indicative of AIH then I guess it is. Dany may know more - sometimes different countries show results in different ways. The mitochondrial antibody suggests there may be a PBC element or overlap I think. Again Dany may know more.
With AIH the normal treatment is steroids and then immunosuppressants so the steroids can be reduced. But with normal liver function tests many doctors would delay treatment until they are sure of a diagnosis - and even then a policy of watchful waiting may be best.
People with AIH do very well - even if there is cirrhosis - which is what I have. Medication can halt the progression, you are monitored for complications and there is no reason why it should ever get worse. If it is either of the other 2 types of autoimmune liver disease then the usual treatment is a bile salt called ursodeoxycholic acid - usually shortened to urso which really helps with symptoms. If there is an overlap of two different diseases then the doc may decide to treat just the main one or both. There is usually limited impact on normal activities although sometimes it can be hard to get the balance of meds right initially.
So my advice would be to listen to what your doc says and not to be surprised if he suggests more tests including a biopsy. He is just collecting the information he needs to decide what the most likely diagnosis is and the best way forward. He may decide to just monitor you further for now. If he does suggest steroid treatment now then do ask about
the possibility of having budesonide rather than prednisolone. It is a steroid that is absorbed by the liver and small intestine so there is much less getting out into the rest of your system -and so side effects are generally much reduced.
I realise that I have thrown a lot of information at you and you are pretty worried anyway. Please take comfort from your normal liver function tests and the fact that autoimmune liver diseases are controllable.
