目的探讨胸腔积液中结核杆菌DNA(Tb-DNA)检测对结核性胸膜炎的诊断价值。方法采用PCR方法检测68例胸腔积液患者胸水TB-DNA含量,与胸水涂片找抗酸杆菌比较其诊断结核性胸膜炎的敏感性、特异性。结果 Tb-DNA检测与涂片找抗酸杆菌诊断结核性胸膜炎的敏感性为42.5%、0%,特异性为92.9%、100.0%,P<0.05。结论胸腔积液Tb-DNA检测适用于结核性胸腔积液的早期诊断。
Objective To investigate the diagnostic value of Tb-DNA in pleural effusion for tuberculous pleurisy. Methods The PCR method was used to detect the content of TB-DNA in pleural effusion of 68 patients with pleural effusion. The sensitivity and specificity of TB-DNA in diagnosing tuberculous pleurisy were compared with pleuropneumonia smear. Results The sensitivity and specificity of Tb-DNA detection and smear-finding acid-fast bacilli in diagnosis of tuberculous pleurisy were 42.5%, 0%, specificity of 92.9%, 100.0%, P <0.05. Conclusion Pleural effusion Tb-DNA test is suitable for the early diagnosis of tuberculous pleural effusion.
