儿童HIV感染多于围产期,1岁以后发生获得性免疫缺陷征群(AIDS),HIV导致肺部感染最常见的临床表现为细菌或病毒的重复感染及条件致病菌感染,最终发展为慢性呼吸功能不全,大多死于反复感染。HIV感染肺部最为常见的病理改变是慢性淋巴样增生。作者回顾分析了250多例AIDS儿童,将其肺活检病理改变与肺部X线表现进行对照,以阐明肺部特征性X线表现的病理基础。 儿童免疫疾病种类繁多,病理上形成系列的肺部慢性淋巴样浸润,其中主要是肺淋巴样增生 HIV infection in children is more than perinatal, acquired immunodeficiency syndrome (AIDS) after 1 year of age, the most common clinical manifestation of HIV-induced pulmonary infection is repeated bacterial or viral infection and opportunistic pathogen infection, eventually developing into Chronic respiratory insufficiency, mostly died of recurrent infections. The most common pathological change in HIV-infected lungs is chronic lymphoid hyperplasia. The authors retrospectively analyzed more than 250 AIDS children and compared their lung biopsy pathology with lung X-ray findings to elucidate the pathological basis of characteristic lung manifestations. A wide range of childhood immune diseases, the pathological formation of a series of chronic pulmonary lymphoid infiltration, which is mainly pulmonary lymphoid hyperplasia
