在HIV血清阳性病例中肺部感染是发病和死亡的重要原因。仅靠普通痰液检查诊断肺部感染,特别是诊断卡氏肺囊虫肺炎(PCP),有一定困难。作者用纤维支气管镜(FB)作支气管肺泡灌洗(BAL)及活检,将获得的灌洗液及病理标本进行多种微生物学检查。研究对象符合下列标准:(1)ELISA和Western印迹试验证实有HIV感染,(2)有肺部感染症状,(3)胸部X线或CT检查异常。受试者共90例,76例为
Pulmonary infection is an important cause of morbidity and mortality in HIV seropositive cases. It is somewhat difficult to diagnose lung infections only by ordinary sputum examination, especially for diagnosis of Pneumocystis carinii pneumonia (PCP). The authors used fiberoptic bronchoscopy (FB) for bronchoalveolar lavage (BAL) and biopsy, the obtained lavage fluid and pathological specimens for a variety of microbiological examination. The subjects met the following criteria: (1) HIV and HIV infection was confirmed by ELISA and Western blotting; (2) symptoms of pulmonary infection; (3) chest X-ray or CT abnormalities. A total of 90 subjects, 76 patients were
