PLoS ONE:关节炎药物或可用于治疗血液癌症

2015-07-07 佚名 生物谷

近期,谢菲尔德大学的科学家们发现一种既可以治疗关节炎也可以帮助治疗血液癌症的药物。每年在英国大约有3300名患者被诊断为骨髓增生性肿瘤(MPN),该病可引起血细胞过度增长,对生活质量产生重大影响。该病导致人体会产生盗汗、瘙痒和疲劳等症状。MPN通常发生在50岁至60岁左右的人之间,目前治疗方法仅限于阿司匹林,它用来去除多余的血液。最近,药物Ruxolitinib已经被开发并用来缓解病情,但每人每年

近期,谢菲尔德大学的科学家们发现一种既可以治疗关节炎也可以帮助治疗血液癌症的药物。

每年在英国大约有3300名患者被诊断为骨髓增生性肿瘤(MPN),该病可引起血细胞过度增长,对生活质量产生重大影响。该病导致人体会产生盗汗、瘙痒和疲劳等症状。

MPN通常发生在50岁至60岁左右的人之间,目前治疗方法仅限于阿司匹林,它用来去除多余的血液。最近,药物Ruxolitinib已经被开发并用来缓解病情,但每人每年40000英镑的巨额成本尚未经过国家健康和卓越护理研究所(NICE)批准。

Martin Zeidler 博士发现,甲氨蝶呤(MTX)与药物Ruxolitinib以同样的方式运作。他说:“考虑到低剂量甲氨蝶呤一年只花费30英镑左右,MTX可能会提供给成千上万患者治疗的一种选择,该药也成为卫生保健系统的巨大储蓄资源。”

“因为MTX是世界卫生组织的“基本药物”,这也意味着该药物可以广泛用于发展中国家。”

低剂量MTX通常用于治疗炎症性疾病包括类风湿性关节炎、克罗恩氏病和牛皮癣,而且几乎没有副作用。较高剂量的甲氨蝶呤用于治疗某些癌症,产生的副作用和某些化疗副作用类似。

Zeidler博士现在正在进行临床试验研究利用低剂量MTX来治疗骨髓增生性肿瘤。“我们有可能彻底改变慢性疾病的治疗方法,该方法对患者和资金消耗都能平衡,是最终的一种新的治疗选择。”他补充道。

Nell Barrie说:“发现现有药物的新用途是一个用来加速改善治疗的伟大方法,这些药物以前已经安全通过测试。甲氨蝶呤作为化疗药物已经用于几种类型的癌症,早期的研究表明,低剂量的甲氨蝶呤具有治疗某些血液疾病的潜力。”
