摘要:
摘 要 目的:探讨Gene Xpert MTB/RIF对肺泡灌洗液中结核分枝杆菌及利福平耐药的早期诊断价值。方法:选取891例确诊肺结核患者为观察组,109例排除结核病患者为对照组,取肺泡灌洗液行浓缩集菌涂片抗酸染色、分枝杆菌液体培养及Gene Xpert MTB/RIF检测,比较两组患者Gene Xpert MTB/RIF检测阳性率及观察组三种检测方法的阳性率;分析观察组Gene Xpert MTB/RIF法对涂阳及涂阴标本中结核分枝杆菌的检测效能;并以分枝杆菌液体培养药敏试验结果为金标准,对Gene Xpert MTB/RIF法检测利福平耐药性的效能进行评价。结果:肺泡灌洗液Gene Xpert MTB/RIF法检测观察组阳性率为712%>对照组18%(P<005)。观察组肺泡灌洗液三种检测方法阳性率比较:Gene Xpert MTB/RIF检测法(712%)>分枝杆菌液体培养法(367%)>浓缩集菌涂片抗酸染色(212%),经两两比较,三者结果差异均有统计学意义(P<005)。对观察组中涂阳标本的检测,分枝杆菌液体培养阳性率为894%、Gene Xpert MTB/RIF法的阳性率为931%,两种检测方法结果比较差异无统计学意义(P>005);对涂阴标本的检测,分枝杆菌液体培养的阳性率为225%、Gene Xpert MTB/RIF法的阳性率为652%,两种检测方法结果比较差异有统计学意义(P <005)。Gene Xpert MTB/RIF检测利福平耐药灵敏度为1000%、特异度为990%,两种方法一致性较高。结论:Gene Xpert MTB/RIF检测法能够快速、特异地同时检测肺泡灌洗液中结核分枝杆菌及利福平耐药性,尤其适用于对临床上涂阴肺结核患者的早期诊断。
Abstract:
Abstract Objective:To investigate the value of Gene Xpert MTB/RIF detection in bronchoalveolar lavage fluid (BALF) for the early diagnosis of pulmonary tuberculosis Methods: The BALF samples were obtained from 891 cases of pulmonary tuberculosis (study group) and 109 nonpulmonary tuberculosis patients (control group) The concentrated smear antiacid staining, mycobacterium liquid culture and Gene Xpert MTB/RIF detection in BALF were performed in two groups The results were compared and analyzed Results: The Gene Xpert MTB/RIF positive rate in BALF of study group was higher than that of control group (712% vs18%,P<005) In study group, the positive rates of concentrated smear antiacid staining, mycobacterium liquid culture and Gene Xpert MTB/RIF were 212%,367% and 712%, respectively, the differences were significant after twotwo comparison (P<005) For the smearpositive specimens in study group, no significant difference was found between the positive rate of mycobacterium liquid culture and that of Gene Xpert MTB/RIF (894% vs931%,P>005 ) For the smearnegative specimens in study group, the positive rate of Gene Xpert MTB/RIF was higher than that of mycobacterium liquid culture (652% vs 225%,P<005) With the mycobacterium liquid culture drug sensitivity test as the gold standard, the sensitivity and specificity of Gene Xpert MTB/RIF for detection of rifampicinresistant were 1000% and 990%, respectively Conclusion:Gene Xpert MTB/RIF is a rapid and specific method to detect〖LM〗 MTB and RIF resistance in BALF, especially for smearnegative patients It exhibits a significant role in value for the early diagnosis of pulmonary tuberculosis
