Clinical Insights: Transitioning from Misdiagnosis to Effective Management of ANCA-Negative Severe EGPA with Mepolizumab—Lessons in Eosinophil-Directed Therapy
To present the diagnostic and treatment journey of a patient with ANCA-negative eosinophilic granulomatosis with polyangiitis (EGPA) and evaluate the effectiveness of mepolizumab.
Approach:
Case Report: A 33-year-old female patient with a history of asthma and chronic rhinosinusitis was diagnosed with severe EGPA after experiencing multi-organ involvement. Treatment with mepolizumab was initiated after discontinuation of omalizumab.
Key Findings:
Mepolizumab (300 mg every 4 weeks) led to symptom resolution and allowed for glucocorticoid tapering.
The patient was diagnosed with severe EGPA after a complex clinical course, including myocarditis and eosinophilia.
Mepolizumab dosing interval was successfully extended to 8 weeks while maintaining remission.
Interpretation:
Limitations:
The application experience of mepolizumab in ANCA-negative severe EGPA remains limited.
The case report is based on a single patient, limiting generalizability.
Conclusion:
The case highlights the importance of careful evaluation for EGPA in patients with asthma before initiating biologic therapy.
Achievable goals, activity tracking, and social support are among the strategies JAMA researchers recommend for patients with chronic medical conditions.
