摘要: 采用吉氏染色法检查艾滋病患者有耶氏肺孢子虫(菌)肺炎临床表现者痰液和支气管肺泡灌洗液(BALF)中的耶氏肺孢子虫(菌)。抽取部分留痰患者(500例)血液,检测CD4+淋巴细胞。结果显示,痰液标本耶氏肺孢子虫(菌)的阳性率(46.8%, 845/1 806)显著低于BALF标本(55.8%, 106/190)(P<0.05)。耶氏肺孢子虫(菌)阳性患者有临床症状的比例(96.6%, 816/845)显著高于阴性者(64.0%, 615/961)(P<0.05)。患者血液中CD4+淋巴细胞数量越少,耶氏肺孢子虫(菌)阳性率越高,CD4+细胞数量>200×106/L组、200×106/L~100×106/L组和<100×106/L组的耶氏肺孢子虫(菌)阳性率分别为12.0%(6/50)、 39.0%(39/100)和54.6%(191/350)(P<0.05)。吉氏染色法是较好的检查耶氏肺孢子虫(菌)的方法,简单易行,容易推广,但需积累经验。

Abstract: Pneumocystis jirovecii was detected in sputum samples and bronchoalveolar lavage fluid (BALF) obtained from HIV/AIDS patients complicated with Pneumocystis jirovecii poneumonia by Giemsa staining. CD4+ T lymphocytes of 500 patients were counted by flow cytometer. P. jirovecii positive rate in sputum samples (46.8%, 845/1 806) was significantly lower than that of BALF (55.8%, 106/190)(P<0.05). The proportion of patients developing clinical symptoms in P. jirovecii positive cases (96.6%, 816/845) was higher than that of P. jirovecii negative cases (64.0%, 615/961)(P<0.05). P. jirovecii positive rate increased with the decrease of CD4+ T lymphocyte number. P. jirovecii positive rates in cases with CD4+ >200×106/L, CD4+ 200×106/L-100×106/L, and CD4+<100×106/L were 12.0%(6/50), 39.0%(39/100), and 54.6% (191/350), respectively (P<0.05). Giemsa staining is an efficient, simple and feasible method for P. jirovecii detection, relying on the experience and skill of the operator.
