Churg-Strauss vasculitis in a patient treated with omalizumab

Omalizumab is a new anti-IgE treatment for severe-persistent allergic asthma. In this case presentation, we report the clinical features of a patient with Churg-Strauss syndrome (CSS) diagnosed after five months of omalizumab treatment. Administration of anti-IgE quickly improved asthma symptoms and enabled the gradual reduction and suspension of systemic steroids. After the suspension of steroids, vasculitis became evident and CSS was diagnosed. Here, we report the clinical course of this patient to evaluate the efficacy of omalizumab in CSS
