In contrast, treatment selection may be challenging in women wishing to preserve fertility because cyclophosphamide carries a risk of gonadal toxicity. We report a 40-year-old woman with a history of asthma, eosinophilic chronic rhinosinusitis, and eosinophilic otitis media who developed postpartum-onset EGPA and presented with neurological and cutaneous manifestations. Elevated cardiac troponin I levels and newly developed electrocardiographic abnormalities suggested subclinical myocardial injury despite the absence of cardiac symptoms. Intravenous methylprednisolone pulse therapy was initiated immediately. Because cardiac troponin I levels showed no early decline after glucocorticoid initiation, and glucocorticoid monotherapy was considered potentially insufficient to control eosinophil-mediated myocardial injury, additional eosinophil-targeted therapy was selected after shared decision-making that balanced fertility preservation with the need for prompt disease control. Benralizumab was chosen because of its potent eosinophil-depleting effect. Peripheral eosinophils rapidly decreased to zero, troponin I normalized by Day 26, and glucocorticoids were successfully discontinued within 5 months. To our knowledge, this is the first report of benralizumab used as part of a fertility-preserving remission-induction strategy to avoid cyclophosphamide in a woman with EGPA and cardiac involvement. This approach may represent an individualized therapeutic option for carefully selected patients in whom fertility preservation is an important treatment consideration.</p>","PeriodicalId":94146,"journal":{"name":"Modern rheumatology case reports","volume":" ","pages":""},"PeriodicalIF":0.9,"publicationDate":"2026-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148868514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
