免疫组织化学及PCR技术在淋巴结结核病理诊断中的应用价值
Clinical application of immunohistochemistry and PCR technique in pathological diagnosis of tuberculous lymphadenitis
摘要
Abstract
Objective To evaluate the clinical value of immunohistochemistry (IHC) and polymerase chain reaction (PCR) methods in pathological diagnosis of tuberculous lymphadenitis. Methods Paraffin-embedded tissue specimens from 48 patients with tuberculous lymphadenitis who had undergone radical resection (the tuberculosis (TB) group) and 21 cases with other diseases in lymph node (the non-TB group) were collected during Jan 2012 to Jul 2013 in Beijing Chest Hospital, Capital Medical University. One-step IHC using antibody targeting Ag85B,Taqman fluorescent quantitative PCR and acid-fast staining were conducted. Their diagnostic efficiency were analyzed, taking the clinical final diagnosis as golden standard. Results The IHC and PCR showed significantly higher sensitivity than that of acid-fast staining (χ2 =6.27,P=0.012; χ2 =10.84,P=0.001,respectively),by the results of 52.1% (25/48) and 60.4% (29/48) versus 27.1% (13/48). However, there was no significant difference in sensitivity between IHC and PCR (χ2 =0.68,P=0.411). The detection results of IHC,PCR and acid-fast staining in non-TB group were all negative,with a specificity of 100% (21/21) for each test. The IHC and PCR had higher negative predictive value and accordance rate than acid-fast staining (47.7% (21/44),52.5% (21/40),37.5% (21/56), respectively; 66.7% (46/69), 72.5% (50/69),49.3% (34/69), respectively). Conclusion IHC and PCR methods are simple and have higher sensitivity compared to acid-fast staining method. IHC and PCR showed good clinical application value in pathological diagnosis of tuberculous lymphadenitis.关键词
