Abstract

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare but devastating vasculitis characterised by perivascular eosinophilic inflammation, severe asthma, peripheral eosinophilia and sinonasal disease, frequently complicated by cardiac, neurological or renal involvement [1, 2]. The mainstay of therapy for EGPA is use of systemic corticosteroids (OCS), with or without concomitant immunosuppression with methotrexate, azathioprine, cyclophosphamide or rituximab [3, 4]. The long-term use of these agents is associated with significant drug-related morbidity and the risk of relapse in EGPA patients remains significant despite treatment [1, 5]. Interleukin (IL)-5 is a critical cytokine regulating eosinophil development, migration and activation [2]. In EGPA, high doses of the IL-5 neutralising antibody mepolizumab lead to improved disease control and reduced requirement for OCS therapy, with an excellent safety profile [6, 7]. Reslizumab is another IL-5 neutralising antibody currently licensed for the treatment of severe eosinophilic asthma [8]; however, there are – to our knowledge – no published data exploring the utility of reslizumab in the management of EGPA. Here, we report clinical and patient-reported outcomes in a cohort of treatment-refractory, OCS-dependent EGPA patients with severe asthma commenced on reslizumab. Blockade of interleukin-5 with reslizumab appears to have significant oral corticosteroid sparing effects in patients with eosinophilic granulomatosis with polyangiitis and severe eosinophilic asthma http://bit.ly/2D2yYSK
