A case of cardiac arrest and spontaneous renal hemorrhage in a male patient with persistent eosinophilia: highlighting the importance of early diagnosis of eosinophilic granulomatosis with polyangiitis

Abstract: Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare multi-system disease that presents significant diagnostic challenges due to its complexity and low incidence (White and Dubey, 2023). It affects males and females equally, though males may exhibit more active disease at diagnosis and often require more aggressive treatment (Liu et al., 2023). The hallmark features of EGPA include delayed-onset asthma, eosinophilia in tissues and blood, and vasculitis affecting small to medium-sized arteries (White and Dubey, 2023). EGPA falls under the category of antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV), whereas only about half of EGPA patients test positive for ANCA (Khoury et al., 2023).

Key words: Eosinophilic granulomatosis with polyangiitis (EGPA); Idiopathic hypereosinophilic syndrome (I-HES); Cardiac arrest; Spontaneous renal hemorrhage

摘要:嗜酸性肉芽肿性多血管炎(EGPA)是一种罕见的多系统性疾病,其诊断充满挑战,尤其是在病情复杂且发病率低的情况下。本文报告了一例58岁男性患者,既往有10年哮喘病史和1年特发性嗜酸性粒细胞增多症(I-HES)病史。患者因持续性嗜酸性粒细胞增多并伴随心脏骤停和自发性肾出血(SRH)而住院治疗。经心肺复苏后,患者因肾破裂出血接受了右肾切除术,肾脏活检结果显示血管闭塞及嗜酸性粒细胞浸润,最终确诊为EGPA。患者在糖皮质激素和免疫抑制剂联合治疗后取得显著疗效。本文强调了早期识别和及时干预在EGPA管理中的重要性。
