Abstract

Interstitial pneumonitis without evidence of Pneumocystis jiroveci infection has been described in the patients infected with immunodeficiency virus (HIV). Nonspecific interstitial pneumonitis (NSIP) is the most commonly observed pathologic diagnosis.

The etiology of NSIP in HIV infected patients is unknown. We retrospectively studied 6 cases of NSIP that were diagnosed with transbronchial biopsies. The etiologic causes of NSIP were evaluated retrospectively by reviewing the inpatient and outpatient charts. The medical records from other institutions were also reviewed when available. We concluded that cocaine abuse, disseminated Mycobacterium avium complex infection, cytomegalovirus (CMV) pneumonitis, and immune reconstitution syndrome were the potential causes of NSIP in our patients with HIV infection.

获得性免疫缺陷综合征非特异性间质性肺炎的病因学
在感染免疫缺陷病毒(HIV)的患者中,曾报道过没有肺囊虫感染的间质性肺炎。非特异性间质性肺炎(NSIP)是最常见的病理诊断。HIV感染患者NSIP的病因尚不清楚。我们回顾性研究了6例经支气管活检诊断为NSIP的病例。通过回顾住院和门诊病历,对NSIP的病因进行回顾性评价。如果有其他机构的医疗记录,也进行了审查。我们认为,可卡因滥用、播散性鸟分枝杆菌复合感染、巨细胞病毒(CMV)肺炎和免疫重建综合征是HIV感染患者NSIP的潜在原因。
