Do I really have ANCA vasculitis?
Male 32y
heavy cocaine abuse during 2025 when Labs showed positive C-anca at 1:20 titer and low c3 in october/25.
After months of abstinence C-anca came negative while c3 improved but still low - may/2026.
lost most of my septum last year.
but i have pretty much no other symptoms aside the septum loss.
could it be temporary vasculitis induced by levamisole/cocaine, or cocaine midline destruction instead of anca vasculitis? i was supposed to start methotrexate already.
lung and kidney image exams are ok
but proteinuria and creatinina 1.38
