About Eosinophilic Granulomatosis with Polyangiitis
Eosinophilic granulomatosis with polyangiitis is a form of vasculitis (inflammatory vessel disease) that affects blood flow to your lungs and gastrointestinal tract. The heart and kidneys can also be affected, but this is less common. As a result of this disrupted blood flow, these tissues can develop regions of inflammations comprised of white blood cells. These masses are called granulomas and they impair organ function. Patients with EGPA have a higher number of white blood cells called eosinophils that are associated with allergies.
Along with microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA), EGPA is an anti-neutrophil cytoplasmic autoantibody (ANCA)-associated vasculitis. In these diseases, vascular inflammation is caused by antibodies called ANCAs.
