简介：目的对2HRZE/4H3R3和2H3R3Z3E3／4H3R3治疗初治涂阳肺结核病患者社会效果评价，为结核病的社会控制提供依据。方法应用中国卫生部结核病控制项目2HRZE/4H3R3方案，治疗初治涂阳肺结核病人的监测资料和2003年对《中国结核病控制规划(2001—2010)))阶段评估，抽查“世界银行贷款+中国结核病控制项目”2H3R3Z3E3/4H3R3方案治疗初治涂阳肺结核病人治疗的资料进行分析。结果在落实较好的全程督导服药治疗下，两方案已达到国家规划目标。目前2H3R3Z3E3/4H3R3未能达到国家规划目标，治愈率明显较强化期每日服药方案低，而失败率、丢失率、副反应停药率明显较高。结论经费落实不到位导致患者全程督导服药治疗不能很好落实，是影响化疗效果的主要原因。由于全程督导服药治疗不能很好落实，致使全程隔日服药方案不能胜任规划目标的要求，提示结核病控制的方向。
简介：摘要目的探究2H3R3Z3E3/4H3R3化疗方案在肺结核治疗、预后方面的应用效果。方法选取我院2012年6月-2014年6月期间收治的肺结核患者90例，根据患者年龄随机分成三组，即青年组、中年组及老年组，分别为30例，三组患者均给予2H3R3Z3E3/4H3R3化疗方案，观察比较三组患者的痰转阴率、病灶吸收率及不良反应发生率。结果青年组和中年组患者的痰菌转阴率及空洞吸收率明显高于老年组（P＜0.05），但青年组和中年组比较无统计学意义(P＞0．05)；老年组患者的不良反应发生率明显高于青年组和中年组（P＜0.05），但青年组和中年组比较无统计学意义(P＞0．05)。结论对肺结核患者应用2H3R3Z3E3/4H3R3化疗方案治疗效果显著，安全性也较高，但对于老年患者应注意观察。
