摘要
目的采用氢质子磁共振波谱成像研究月经相关性偏头痛(MRM)不同状态下脑代谢情况,并探讨其与临床特征及雌激素孕激素的相关性。资料与方法招募2019年4月—2022年8月河南科技大学第一附属医院神经内科门诊确诊的MRM患者36例,同时招募年龄和受教育程度相匹配的正常女性29例。采用氢质子磁共振波谱成像分别于发作间期(卵泡后期)、发作期(围月经期)检测内侧前额叶皮层(mPFC)和丘脑的主要代谢物N-乙酰天门冬氨酸、γ-氨基丁酸(GABA)、谷氨酸复合物(Glx)和胆碱(Cho)与肌酸(Cr)的比值。每次MRI成像当天同时采集静脉血检测雌激素孕激素水平。比较发作间期、发作期各脑区两组间代谢物比值及激素水平、围月经期激素下降率的差异,同时观察MRM组从发作间期到发作期脑代谢的变化。结果MRM患者较正常人卵泡后期、围月经期雌激素孕激素水平及围月经期雌激素孕激素下降率均无显著差异(P>0.05)。在发作间期,MRM组左侧mPFC Cho/Cr较对照组降低(U=-2.957,P=0.003),且与发作频率呈负相关(r=-0.398,P=0.018)。在发作期,MRM组左侧mPFC GABA/Cr较对照组降低(U=-2.015,P=0.044),左侧丘脑Glx/Cr较对照组升高(t=2.213,P=0.033),上述结果与临床特点均无显著相关性(P>0.05)。MRM患者从发作间期到发作期GABA/Cr未发生显著变化(P>0.05),而右侧丘脑Glx/Cr显著升高(t=-2.181,P=0.038),右侧丘脑Cho/Cr显著升高(Z=-2.414,P=0.016)。结论MRM患者存在与正常人不同的脑代谢情况,且伴随头痛发作存在脑代谢的变化,但本研究未发现与月经周期相关雌激素孕激素的差别,其神经机制仍需进一步研究。
Purpose Hydrogen proton magnetic resonance imaging was used to study the brain metabolism of menstrual-related migraine(MRM)in different states,and to investigate its correlation with clinical features and estrogen and progesterone.Materials and Methods We recruited 36 patients with MRM diagnosed by neurology outpatient experts of the First Affiliated Hospital of Henan University of Science and Technology from April 2019 to August 2022,and also recruited 29 normal women with age-and education-matched.Proton magnetic resonance spectroscopy was used to assess neurochemical brain changes during interictal period(late follicular phase)and ictal period(perimenstrual phase)in them.The point resolved spectroscopic sequence was used to focus on the bilateral medial prefrontal cortex(mPFC)and bilateral thalamus.Sex hormone levels were collected on the same day of MRI acquisition.The ratios of NAA/Cr,GABA/Cr,Glx/Cr and Cho/Cr were observed.Metabolite changes and hormone levels were investigated among two groups.Furthermore,metabolite changes were investigated in a longitudinal design during the interictal period and ictal period.Results There were no significant differences in the levels of estrogen and progesterone both in the late follicular and perimenstrual periods.There were no significant differences in decline rate of them in perimenstrual periods between patients and normal people(P>0.05).During interictal period,the ratio of Cho/Cr in the region of left mPFC was lower significantly in the MRM group than that of control group(U=-2.957,P=0.003)and showed a significant negative correlation with attack frequency(r=-0.398,P=0.018).During ictal period,the women with MRM had significantly lower the ratio of GABA/Cr in the left mPFC and higher the ratio of Glx/Cr in the left thalamus compared to those of controls(U=-2.015,P=0.044;t=2.213,P=0.033).We found no significant correlations between these results and magraine characteristics(P>0.05).In addition,we found the ratio of GABA/Cr did not change(P>0.05),the ratio of Glx/Cr and Cho/Cr in right thalamus increased from interictal towards the ictal state for MRM patients(t=-2.181,P=0.038;Z=-2.414,P=0.016).Conclusion The present study suggests the existence of distinct cerebral metabolism states between MRM and control,and there are dynamic changes in cerebral metabolism with headache attacks.However,there is no significant difference in estrogen and progesterone from normal women,and its neural mechanism still needs to be further studied.
