We reported a unique case with the coexistence of classic and cutaneous polyarteritis nodosa (PAN), and microscopic polyangiitis (MPA) in hepatitis virus-associated vasculitis. A 77-year-old Asian man presented with extremity weakness and weight loss found to have bilateral foot drop and rash on his hands and legs. Labs reveal positive for hepatitis B core antibody and perinuclear-antineutrophil cytoplasmic antibody (p-ANCA), decreased C3 and C4 levels. Skin biopsy of rash shows medium vessel vasculitis suggesting PAN. Interestingly, renal biopsy showed features of necrotising medium-sized arteritis consistent with PAN and focal crescentic glomerulonephritis consistent with MPA. The patient was treated with 1 g of solumedrol daily for 3 days, followed by oral steroids and cyclophosphamide treatment for vasculitis, and entecavir for chronic hepatitis B infection, resulting in resolution of symptoms. The patient has not had a relapse at 6 months.
我们报告了一例伴有经典型和皮肤型结节性多动脉炎(PAN)以及乙型肝炎病毒相关性血管炎中小血管显微镜下多血管炎(MPA)共存的特殊病例。一名 77 岁亚裔男性因四肢无力和体重减轻就诊,发现双侧足下垂和手部及腿部皮疹。实验室检查示乙型肝炎核心抗体和核周型抗中性粒细胞胞质抗体(p-ANCA)阳性,C3 和 C4 水平降低。皮疹皮肤活检显示中等血管血管炎,提示为 PAN。有趣的是,肾活检显示为坏死性中等大小动脉炎,符合 PAN,以及局灶性新月体性肾小球肾炎,符合 MPA。患者接受了 1g 甲泼尼龙静脉滴注 3 天,随后接受口服类固醇和环磷酰胺治疗血管炎,以及恩替卡韦治疗慢性乙型肝炎感染,症状得到缓解。患者在 6 个月时未复发。
