Efficacy and Safety of Mepolizumab in Patients With Eosinophilic Granulomatosis With Polyangiitis: A Single-Center Experience

Year: 2024

Type: article

Abstract: Eosinophilic granulomatosis with polyangiitis (EGPA), previously known as Churg-Strauss syndrome, is a systemic vasculitis characterized by eosinophil-rich, necrotizing granulomatous inflammation primarily affecting the respiratory tract with necrotizing vasculitis of small- to medium-sized arteries. In this case series, we retrospectively evaluated the efficacy and safety of mepolizumab in seven patients diagnosed with EGPA who presented to the Department of Allergy and Clinical Immunology at Cleveland Clinic Abu Dhabi. The variables assessed before and after mepolizumab treatment included Birmingham Vasculitis Activity Score (BVAS), prednisolone dose, Asthma Control Test (ACT) score, and blood eosinophil count (BEC). We found a significant reduction in BVAS and prednisolone dosage with clinical improvements in asthma symptoms after treatment with mepolizumab. Our case series, the first from the Middle East on the use of mepolizumab in EGPA, demonstrates that mepolizumab is a safe and effective treatment for patients with EGPA.
