BACKGROUND: Data on the presentation and management of patients with eosinophilic granulomatosis with polyangiitis (EGPA) in private practice are limited.
OBJECTIVE: We sought to characterize the profiles and disease burden of patients with EGPA in a real-world private practice setting.
METHODS: This was a retrospective, noninterventional, longitudinal study (GSK ID: 217426) of US Allergy Partners network data. For patients with a diagnosis of EGPA, confirmed by 2 or more EGPA clinical features, index was defined as their first visit with an Allergy Partners physician (January 2007-June 2021); postindex lasted until loss of follow-up or study end (December 2021). Patient characteristics at index, physician characteristics at any time, symptoms, treatment characteristics, and clinical outcomes postindex were assessed.
RESULTS: Of 52 patients (median follow-up, 3.7 years), 75% were diagnosed with EGPA outside the Allergy Partners network. Each patient received care from a median (Q1-Q3) of 4.0 (3.0-5.0) physician specialties. Most had asthma (92%), rhinitis (75%), and sinusitis (62%) and experienced a mean ± SD of 18.1 ± 4.3 distinct self-reported symptoms. Most (85%) used oral corticosteroids, with 73% (32 of 44) on daily doses of more than 12 mg; 60% used mepolizumab. Overall, 75% of patients (39 of 52) achieved a response (improved/controlled symptoms); 46% (24 of 52) achieved controlled status after worsened, unchanged, or active symptoms, and of these 38% (9 of 24) relapsed.
CONCLUSIONS: The complex private practice presentation of EGPA, with heterogeneous patient response to standard treatments, highlights a significant disease burden and continued need for optimized treatment strategies within a multidisciplinary team approach.
