Early mepolizumab treatment in EGPA, guided by biomarkers, led to steroid-free MPO-ANCA seroconversion. This suggests a potential steroid-sparing approach for ANCA-positive EGPA patients.
Area of Science:
- Rheumatology
- Immunology
- Clinical Medicine
Background:
- Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare autoimmune vasculitis.
- Management often involves corticosteroids, leading to potential long-term side effects.
- MPO-ANCA is a key biomarker in certain vasculitides.
