Diagnostic Criteria: EGPA Criteria Used in Phase 3 Trials!
Asthma plus eosinophilia (>1.0 x 109L and/or >10% of leukocytes)
plus at least 2 of the following
+ Abiopsy showing histopathological + Sino-nasal abnormality
evidence of eosinophilic vasculitis, + Cardiomyopathy (established by
or perivascular eosinophilic echocardiography or MRI)
infiltration, or eosinophil-rich = Glomerdionenhritis Thematuri
granulomatous inflammation omerlonep its ( ematurla,
red cell casts, proteinuria)
+ Alveolar hemorrhage
(by bronchoalveolar lavage)
+ Palpable purpura
+ Positive test for ANCA (MPO or PR3)
+ Neuropathy, mono or poly
(motor deficit or
nerve conduction abnormality)

+ These classification criteria should be applied to classify a patient as having eosinophilic granulomatosis with
polyangiitis when a diagnosis of small- or medium-vessel vasculitis has been made
«Alternate diagnoses mimicking vasculitis should be excluded prior to applying the criteria

Despite the rarity of EGPA, the range of organ systems involved
and its relapsing-remitting nature exert a large burden on patients
and healthcare systems, including
+ Substantial levels of OCS use
+ Asthma exacerbations

There are not enough doctors aware or educated in the disease making it extremely
difficult to find care. Insurance companies make it difficult for sick patients to get the
medicine they need, especially biologic medicines and steroid inhalers.

Addition of Azathioprine to Glucocorticoids for Nonsevere
EGPA Does Not Improve Remission Rates!
+ In a randomized controlled trial,47.8% of patients receiving azathioprine vs 49% of patients
on placebo had remission induction failures or relapses
+ Azathioprine also did not improve relapse risk, was not steroid sparing, and did not diminish
the EGPA asthma/rhinosinusitis exacerbation rate in 95 patients with nonsevere systemic
necrotizing vasculitides (51 with EGPA) m
