Laboratory tests revealed peripheral eosinophilia and anti\u2010myeloperoxidase anti\u2010neutrophil cytoplasmic antibody (MPO\u2010ANCA) negativity. Chest computed tomography revealed diffuse ground\u2010glass opacities, interlobular septal, and bronchial wall thickening, suggesting eosinophilic pulmonary infiltration. Based on this clinical presentation and the ACR\/EULAR 2022 classification criteria, as well as the Japanese Ministry of Health, Labour and Welfare criteria, eosinophilic granulomatosis with polyangiitis (EGPA) was diagnosed. However, the patient declined treatment with glucocorticoids owing to concurrent diabetes mellitus; therefore, subcutaneous low\u2010dose (100\u2009mg\/month) mepolizumab monotherapy was initiated as an alternative strategy, with the lower dose specifically selected to alleviate the patient's financial burden. Notably, a rapid decrease in eosinophil counts was observed within just 4\u2009days of administration, and remission was achieved and maintained for 2\u2009years. In conclusion, this case suggests that mepolizumab monotherapy may be a viable option for certain patients with non\u2010severe, MPO\u2010ANCA\u2013negative EGPA who cannot tolerate standard high\u2010dose glucocorticoid therapy or have financial constraints.<\/jats:p>","DOI":"10.1002\/ccr3.72480","type":"journal-article","created":{"date-parts":[[2026,4,16]],"date-time":"2026-04-16T05:10:40Z","timestamp":1776316240000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Steroid\u2010Free
