Unfortunately I do have some experience with vasculitis and immune disorders. According to A's Rheumo (and GI agrees) her Differential Diagnoses are - IBD, Primary Immunodeficiency with Autoimmunity, and Systemic Vasculitis (PAN). Apparently IBD would be the more common and easiest to diagnose of the 3 but we're still in the process of waiting and testing.
A has had an MRA (which I would suggest doing at the time of your MRI if doc will agree) which showed some benign defects. An MRA will only detect large vessel vasculitis so A will possibly have a CTA in the future. We've put that off for now due to the risks involved.
As far as immune testing, we started with basic immunoglobulin labs and antibody testing. It looks as if she may have issues with sustaining protection from vaccines but we will retest in early July to see if this is the case. We are waiting on prior auth to have more extensive testing done - B Cell panel, CD45RA/RO, FoxP3, and Toll-like Receptor Function assay. The immune system is such a complicated system and unfortunately testing is a time-consuming (and expensive) process.
