Heart:别嘌呤醇或可降非致命性心梗风险

2015-01-07 小田 译 医学论坛网

西班牙学者们在别嘌呤醇应用者中评估了其非致命性心肌梗死(AMI)风险,结果表明,别嘌呤醇与非致命性AMI风险减少有关,这种相关性似乎呈剂量依赖性和持续时间依赖性。论文1月5日在线发表于《心脏》(Heart)杂志。 该基于人群的病例对照研究纳入了年龄40至90岁的受试者。在主要分析中,研究者排除了既往用过别嘌呤醇或有AMI病史的患者。利用无条件逻辑回归模型校正混淆因素,通过OR值来评估

西班牙学者们在别嘌呤醇应用者中评估了其非致命性心肌梗死(AMI)风险,结果表明,别嘌呤醇与非致命性AMI风险减少有关,这种相关性似乎呈剂量依赖性和持续时间依赖性。论文1月5日在线发表于《心脏》(Heart)杂志。

该基于人群的病例对照研究纳入了年龄40至90岁的受试者。在主要分析中,研究者排除了既往用过别嘌呤醇或有AMI病史的患者。利用无条件逻辑回归模型校正混淆因素,通过OR值来评估别嘌呤醇和非致命性AMI的相关性。

结果显示,研究者确定的非致命性AMI和对照组例数分别为3171例和18525例。与对照组(1.03%)相比,非致命性AMI患者的别嘌呤醇当前应用率较低,为0.82%,OR值为0.52。风险减少来自于男性,即男性OR值为0.44,女性为0.90。不同年龄段的患者风险无差异。

这种效应仅在剂量更大(≥300 mg 的OR=0.30,<300 mg的OR=0.67)和应用时间延长者(<31 天,OR=1.12;31–180天,OR=0.61;>180天,OR=0.21;P趋势=0.001)中可观察得到。

在既往有AMI的患者中,别嘌呤醇应用也可显著减少复发的分险(OR=0.16)。

BCX4208结合别嘌呤醇共同治疗痛风2b阶段取得可喜成果

BioCryst 医药公司公布了,BCX4208结合别嘌呤醇2b阶段随机研究的可喜成果。BCX4208是一种新型日服的口服酶抑制剂,被当做黄嘌呤氧化酶的补充治疗,来满足痛风患者的需要。 此次研究评估了那些接受小于6mg/dl别嘌呤醇单一治疗,但是没有达到血清尿酸治疗效果的痛风患者。 为期24周的2b阶段研究显示BCX4208有很好的安全性和耐受性,能够持续控制血清尿酸的含量保持在正常水平,
