Key points • We performed a systematic literature review and meta-analysis of real-world, observational studies describing the incidence, prevalence, and disease burden associated with eosinophilic granulomatosis with polyangiitis (EGPA). • Based on meta-analysis data from 35 eligible studies reporting incidence and prevalence, the incidence and prevalence of EGPA were low (globally 1.22 cases per million person-years and 15.27 cases per million individuals, respectively). • Among the 49 studies with morbidity and/or healthcare resource data, most reported a large proportion of patients with EGPA relapses and comorbidities of nasal polyps and severe asthma. • Healthcare resource use was also high among patients with EGPA in these studies, with inpatient admissions and emergency department visits reported for 17–42% and 25–42% of patients, respectively. Taken together, these data indicate the substantial disease burden associated with EGPA. |
