34 Male, Diagnosed with Ulcerative Colitis 1 year back noticed ANA IF positive (1:100) "anti-jo-1 positive" (1 positive) while testing for ENA profile. Where as all other Auto ANTIBODIES remains negative.
This was strange finding as i am not with symptoms for muscles pain/weekness or such.
Doctor also performed creatine kinase [Creatine Phosphokinase (CPK)] and lungs xray, both come Normal.
Any idea why this particular antibody shows positive.? Does it have any relation with UC ?
