Supplementary Material for: Gastrointestinal involvement of Eosinophilic Granulomatosis with Polyangiitis with histological evidence of treatment response

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis of small to medium vessels. Gastrointestinal involvement is uncommon and is associated with higher mortality. Treatment is based on empiric evidence. In this article, we report a case EGPA related pancolitis and stricturing small bowel disease managed with a combination of mepolizumab and surgical resection.
