【摘要】 目的　了解产生复治后耐多药肺结核病的有关因素及临床特点。方法　对 1992— 2 0 0 2年10年间收治的复治后耐多药肺结核病人 (MDR PTB)共 6 2 5例进行分析。结果　 6 2 5例复治后MDR PTB病人占同期收治的复治菌 (阳 )病人的 30 .8% ,青壮年男性占大多数。药敏监测提示耐H、R 7例(1.1% ) ;耐 3种药 12 5例 (2 0 .0 % ) ;耐 4种药 4 93例 (78.9% )。初始耐药 19.4 % ,获得性耐药 80 .6 %。农村及城镇病人比例高 ,但有效率低于城市病人。结论　复治后MDR PTB较普通MDR PTB更难处理 ,除经济、文化、地区等因素外 ,医源性因素也是其发病率增高的重要原因。本组初始耐药感染高于全国平均水平。不同地区治疗有效率差异与缺乏专业人员的正规治疗及管理有关。个体化治疗、尤其联合手术治疗能达到较好的效果更多还原

【Abstract】 Objective To determine the occurrence mechanism clinical characteristics multidrug resistant pulmonary tuberculosis (MDR PTB) who received treatment before.Methods The clinical data of 625 cases with MDR PTB received treatment before in Guiyang pulmonary Hospital from 1992 to 2002 was analyzed.Results 625 cases with MDR PTB received treatment before occupied 30.8% in patients of retreatment bacteriological positive PTB.Young and middle age females occupied majority.The results of susceptibility test wereas follows:7 cases with drug resistance results to H.R.
