Neurology:阵发性偏头痛新的生物标记物——神经酰胺

2015-09-10 MedSci MedSci原创

很多人备受阵发性偏头痛的困扰,但是大家对此知之甚少,近日,发表在Neurology的新进研究中,研究人员发现了阵发性偏头痛患者血液中的生物标志物,这可能会对阵发性偏头痛的诊断和治疗有所帮助,当然还需要进一步的研究进行深入调查。 约翰霍普金斯大学医学院B.Lee Peterlin博士说道:“虽然还需要更多的研究来证实这些初步的研究结果,但是发现这个新的生物标志物还是挺激动人心的”。阵发性偏头痛的患者

很多人备受阵发性偏头痛的困扰,但是大家对此知之甚少,近日,发表在Neurology的新进研究中,研究人员发现了阵发性偏头痛患者血液中的生物标志物,这可能会对阵发性偏头痛的诊断和治疗有所帮助,当然还需要进一步的研究进行深入调查。 


约翰霍普金斯大学医学院B.Lee Peterlin博士说道:“虽然还需要更多的研究来证实这些初步的研究结果,但是发现这个新的生物标志物还是挺激动人心的”。阵发性偏头痛的患者每月头痛时间少于15天,相比之下,慢性偏头痛患者头痛时长超过15天/月。 

偏头痛对公众的健康带来重大影响。因为偏头痛可能会导致他们出现抑郁、焦虑、睡眠障碍和疲劳等表现。除了治疗偏头痛的治疗费用,美国偏头痛委员会估计,美国偏头痛治疗间接消费超过200亿美元/年。 尽管研究人员尚不清楚偏头痛的发生机制,但是更进一步的研究有助于干预这种疾病的继续发展,并且有利于治疗疾病。 

在这项研究中,研究人员对52名诊断有偏头痛且的女性(平均每月疼痛5.6天)进行了神经系统检查,同时对36名未患偏头痛的女性进行了同样的检查,即为对照组。研究人员测量了每个参与者的BMI,并收集了他们的血液样本。通过对血液样本进行分析,研究人员发现了一种被称为神经酰胺的脂质,它的作用是调节大脑的炎症反应。 

研究人员发现,相比没有阵发性偏头痛的女性,患有阵发性性偏头痛的女性神经酰胺水平下降。平均而言,阵发性偏头痛患者血液中总神经酰胺含量约6000毫微克/毫升血,而对照组民众的含量为10500毫微克/毫升血。随着机体总神经酰胺水平的增加,民众患患偏头痛的风险降低。研究人员还发现,两种其他类型的脂质会增加患偏头痛的风险。这两种脂质属于鞘磷脂。 

为了检验实验结果,研究人员对14名参与人员的血液标本进行了检测,事实证明,他们可以准确地分辨出患有偏头痛和未患偏头痛的民众。

这项研究非常重要,它为今后探究偏头痛的发病机制和提供治疗方案并研发药物发挥着重要的作用。
