To further improve the diagnostic value of bronchoscopy in the immunosuppressed population presenting with diffuse pulmonary infiltrates, we prospectively investigated the utility of bilateral bronchoalveolar lavage (BAL). We performed 62 bronchoscopies on 52 immunosuppressed patients. Of the 52 patients, 33 had pulmonary infections. The yield for Pneumocystis carinii pneumonia on bilateral BAL was 94 percent (31/33), compared to the 84 percent (51/61) previously obtained with unilateral BAL in our institution. The recovery of P carinii was unilateral in four of five patients without AIDS and in four of 26 patients with AIDS. Transbronchial biopsy gave a yield of 85 percent (11/13). In ten patients with definitive cytomegalovirus (CMV) pneumonia, recovery of CMV by combined culture and cytology was 100 percent. Of nine bronchoscopies with positive cytology for CMV, five showed cytopathologic changes in the BAL from both sides and four in the BAL from one side only. No complications were seen in the 14 patients with thrombocytopenia or the five patients receiving mechanical ventilation. Our findings indicate that bilateral BAL significantly increases the yield for recovery of P carinii (p less than 0.02) and CMV (p less than 0.001) in immunosuppressed patients.
为进一步提高支气管镜检查对免疫抑制人群弥漫性肺浸润的诊断价值，我们前瞻性地研究了双侧支气管肺泡灌洗（BAL）的效用。我们对52例免疫抑制患者进行了62次支气管镜检查。在这52例患者中，33例有肺部感染。双侧BAL检测卡氏肺孢子虫肺炎的阳性率为94%（31/33），而在我们机构之前单侧BAL的阳性率为84%（51/61）。在5例无艾滋病患者中有4例以及26例艾滋病患者中有4例卡氏肺孢子虫的检出为单侧。经支气管活检的阳性率为85%（11/13）。在10例确诊为巨细胞病毒（CMV）肺炎的患者中，联合培养和细胞学检测CMV的阳性率为100%。在9例CMV细胞学检查阳性的支气管镜检查中，5例双侧BAL显示有细胞病理学改变，4例仅单侧BAL有细胞病理学改变。14例血小板减少患者或5例接受机械通气的患者均未出现并发症。我们的研究结果表明，双侧BAL显著提高了免疫抑制患者中卡氏肺孢子虫（p<0.0？此处原文有误，应为p<0.02）和CMV（p<0.001）的检出率。 （注：原文中“p less than 0.02”和“p less than 0.001”的表述在实际翻译时按照正确语法应为“p<0.02”和“p<0.001”，可能原文表述不太准确）
