药敏试验指导下脊柱结核个体化药物治疗

目的 实施结核分枝杆菌药敏试验指导下脊柱结核个体化化疗,探讨其有效性及安全性.方法 46例脊柱结核患者接受手术治疗,术中收集脓液、干酪样组织,常规处理后接种液体培养基,使用BACT/ALERT 3D系统进行结核分枝杆菌快速培养,培养阳性者接种至改良罗氏培养基,按绝对浓度法进行11种药物药敏试验.根据药敏试验结果制定4-5药联合抗结核药物治疗方案.定期(1、3、6、9、12个月,以后每6个月1次)随访,观察血沉、平片、CT三维重建,评估结核活动、骨块融合和畸彤矫正情况.结果 培养阳性率41.3%(19/46),全程平均耗时42 d(30～58 d).耐药率21.7%,其中异烟肼耐药10.8%,利福平和乙胺丁醇耐药2.1%,链霉素耐药6.52%,力克肺疾耐药4.34%,左氧氟沙星耐药17.39%.除4例明显胃肠道反应、1例药物型肝炎患者完成12个月疗程,其余18个月.随访18～44个月,平均25个月,切口均2周内愈合.椎间植骨均获Ⅰ级骨性融合,融合时间9～12个月.结论 根据药敏试验结果组成脊柱结核12～18个月个体化联合化疗方案具有较好的有效性和安全性.

Drug susceptibility-guided individual anti-tuberculous chemotherapy for spinal tuberculosis: report of 46 cases

Objective To investigate the efficacy and safety of individual anti-tuberculous chemotherapy guided by drug susceptibility testing for spinal tuberculosis by analyzing the post-operative follow-up outcomes. Methods In this series,the diagnoses of spinal tuberculosis were established based on clinical,radiological and histological arguments in 46 patients who were admitted from August 2005 to March 2009. Their specimens ( pus or caseous tissue) were collected during surgery. After processed in a routine myco...
