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.嗜酸性肉芽肿性多血管炎（Eosinophilic granulomatosis with polyangiitis, EGPA）是一种罕见的累及中小血管的系统性血管炎。胃肠道受累较为少见，且与更高的死亡率相关。其治疗方案以经验性证据为依据。本文报告1例EGPA相关全结肠炎合并狭窄性小肠病变的病例，该患者采用美泊利单抗联合手术切除的方案进行治疗。
