狼疮性肾炎并肺人巨细胞病毒感染1例及文献复习

人巨细胞病毒感染常见于免疫功能受损的免疫宿主，狼疮性肾炎患者以应用激素及免疫抑制剂治疗为主，可导致其成为人巨细胞病毒感染的免疫宿主。人巨细胞病毒性感染是以受感染细胞形成巨大的A型嗜酸性核内及胞质内包涵体为特征。大多数是无症状隐性感染，在免疫功能低下和婴儿中可引起严重的肺部感染而导致死亡。免疫功能低下患者中症状轻、影像学表现重的人巨细胞病毒性肺炎少见，极易被误诊。本文报道1例狼疮性肾炎并症状轻、影像学表现重的人巨细胞病毒肺炎患者，并复习了国内外相关文献。 

Lupus nephritis complicated with pulmonary human cytomegalovirus infection: A case report and literature review

Human cytomegalovirus infection is common in immunocompromised hosts. Lupus nephritis patients are treated mainly with steroids and immunosuppressive agents, which render the patents more susceptible to human cytomegalovirus infection. Human cytomegalovirus infection is characterized by the formation of large type A eosinophilic intranuclear and cytoplasmic inclusions in infected cells. Most infections are asymptomatic. In immunocompromised patients and babies, this virus can cause severe lung infection and even death. In immunocompromised patients, human cytomegalovirus pneumonia with mild symptoms and severe imaging abnormalities is rare and is easy to be misdiagnosed. Here, we report case of patients with lupus nephritis complicated with human cytomegalovirus pneumonia that have mild symptoms and severe imaging abnormalities, and related literature are reviewed.
