Interferon beta (IFN-) therapy is one of the most commonly prescribed immunomodulatory therapies in relapsing-remitting multiple sclerosis (RRMS). A reversible cerebral vasoconstriction syndrome (RCVS), associated with IFN- use, has been recently described. For this reason, we tested the effect of once a week intramuscular administration of IFN--1A on the function of cerebral vessels in a cohort of RRMS patients. Using transcranial Doppler (TCD) ultrasound, we measured the mean blood flow velocity (MFV) in intracranial vessels 10 h after IFN- administration. Measurements showed a significant increase in MFV compared to the baseline values in some vessels.
干扰素β(IFN-β)治疗是复发缓解型多发性硬化症(RRMS)中最常开的免疫调节治疗之一。最近描述了一种与 IFN-β 使用相关的可逆性脑动脉收缩综合征(RCVS)。因此,我们在一组 RRMS 患者中测试了每周一次肌肉注射 IFN-β1A 对脑血管功能的影响。我们使用经颅多普勒(TCD)超声在 IFN-β 给药后 10 小时测量颅内血管的平均血流速度(MFV)。测量结果显示,与基线值相比,一些血管的 MFV 显著增加。
