Not Applicable
Conditions
Eosinophilic granulomatosis with polyangiitis
Registration Number
JPRN-UMIN000040163
Lead Sponsor
ational Hospital Organization Sagamihara National Hospital
Brief Summary

In active EGPA, 33 proteins, mainly related to eosinophils, type 2 inflammation, and cell adhesion factors, were elevated compared to asthma. In contrast, 12 proteins were decreased with steroid treatment. Fifty-nine proteins, including functional proteins involved in cell proliferation, angiogenesis, and type 3 inflammation as well as eosinophilic inflammation, were altered by the additional administration of mepolizumab. MicroRNA coverage analysis showed 8 significantly different between EGPA and asthma.
