DDW 2013:咖啡可防硬化性胆管炎

2013-05-24 佚名 EGMN

  在消化疾病周(DDW)之前公布的一项纳入超过1,300例受试者的病例对照研究显示,饮用咖啡可预防原发性硬化性胆管炎(PSC),但不能预防原发性胆汁性肝硬化(PBC)。   这项研究由罗切斯特市梅奥医院的Craig Lammert博士及其同事进行,受试者是2002~2013年间的348例PSC患者、530例PBC患者和456名健康对照者。所有受试者完成有关咖啡饮用情况的问卷。   PSC患者

  在消化疾病周(DDW)之前公布的一项纳入超过1,300例受试者的病例对照研究显示,饮用咖啡可预防原发性硬化性胆管炎(PSC),但不能预防原发性胆汁性肝硬化(PBC)。

  这项研究由罗切斯特市梅奥医院的Craig Lammert博士及其同事进行,受试者是2002~2013年间的348例PSC患者、530例PBC患者和456名健康对照者。所有受试者完成有关咖啡饮用情况的问卷。

  PSC患者组和健康对照组在性别构成和年龄(两组的平均年龄分别为57岁和66岁)方面均存在显著差异。此外,PSC组和健康对照组从未饮用咖啡者的比例分别为21%和13%,目前饮用咖啡者的比例分别为67%和78%。在校正年龄和性别后,这些差异仍较为显著。PSC患者组每月人均饮用50杯咖啡,平均有50%的生命时间在经常饮用咖啡。健康对照组每月人均饮用78杯咖啡,平均有67%的生命时间在经常饮用咖啡。

  PBC患者和健康对照者的性别构成存在差异(两组的女性比例分别为89%和74%),但年龄相似(两组的平均年龄均为66岁)。两组目前饮用咖啡者和从未饮用咖啡者的比例无差异。两组在开始饮用咖啡的平均年龄、每月估计咖啡饮用杯数和经常饮用咖啡的生命时间比例方面均无显著差异。

  Lammert博士指出,上述结果提示,PSC和PBC之间存在环境效应差异,这点颇为有趣,因为既往认为咖啡对晚期肝病患者有保护作用。有待回答的关键问题是,PBC为何不受影响?他补充道,PBC并不遵循迄今报告的模型或模式。预期上述结果将促使研究者对与复杂肝病相关的环境因素进行新的研究。在被问到是否应鼓励PSC患者饮用咖啡时,Lammert博士表示现有数据尚不足以支持具体建议,但也不会阻止PSC患者饮用咖啡。

Coffee protects against primary sclerosing cholangitis
Coffee consumption appears to protect against the development of primary sclerosing cholangitis, but not against the development of primary biliary cirrhosis, according to findings from a case-control study involving more than 1,300 subjects.
Average coffee consumption was 50 cups per month among 348 study subjects with primary sclerosing cholangitis (PSC), and those subjects spent an average of 50% of their life actively drinking coffee. Average coffee consumption among 456 healthy controls was 78 cups per month, and those subjects spent an average of 67% of their life actively drinking coffee, Dr. Craig Lammert reported during a press briefing held prior to the annual Digestive Disease Week where the findings will be presented...
