Stopping propylthiouracil and starting strong immune-suppressing drugs and blood-filtering treatments can quickly reverse severe organ damage caused by this rare immune reaction.

What Would Prove This
Per GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this claim, ordered from strongest to weakest.
Whether combination therapy (steroids + cyclophosphamide + plasmapheresis) improves renal and systemic outcomes faster than steroids alone in PTU-induced ANCA vasculitis.
A multicenter RCT of 60 patients with confirmed PTU-induced PR3-ANCA vasculitis and acute kidney injury (creatinine >300 μmol/L), randomized to steroids + cyclophosphamide + plasmapheresis vs. steroids + cyclophosphamide alone, with primary outcome of renal recovery at 4 weeks.
The rate of renal recovery and survival in patients with PTU-induced vasculitis treated with immunosuppression and plasmapheresis compared to supportive care alone.
A prospective cohort of 100 patients with PTU-induced ANCA vasculitis and organ failure, stratified by treatment received (plasmapheresis vs. no plasmapheresis), with 6-month follow-up for renal recovery, relapse, and mortality.
That immunosuppression and plasmapheresis lead to improvement in multiple cases of PTU-induced vasculitis with organ failure.
A case series of 10 patients with PTU-induced ANCA vasculitis and multi-organ failure treated with steroid, cyclophosphamide, and plasmapheresis, documenting time to improvement in creatinine, CRP, and hemoglobin.
