中文摘要:
      目的 采用局部弥散一致性(LDH)探讨终末期肾病(ESRD)继发甲状旁腺功能亢进症(SHPT)患者脑白质改变。方法 选取50例接受血液透析的ESRD患者,根据是否伴有SHPT分为SHPT组(25例)与非SHPT组(25例),利用蒙特利尔认知评估(MoCA)量表评估认知功能,并进行MR平扫及DTI数据采集,对全脑白质纤维LDH值进行基于体素的组间比较。结果 相比非SHPT组,SHPT组出现双侧大脑半球弥漫性、对称分布的LDH减低区及右侧小脑半球局灶性LDH减低区(P均<0.01),LDH值升高区域集中在脑干及小脑(P均<0.01)。SHPT组MoCA总评分与全段甲状旁腺激素(iPTH)水平呈负相关(r=-0.525),与受教育水平呈正相关(r=0.413)、与左侧皮质脊髓束的LDH值呈正相关(r=0.500,P均<0.05);iPTH水平与差异脑区的LDH值均无明显相关(P均>0.05)。结论 LDH值可提供ESRD伴SHPT患者脑白质LDH信息:脑白质LDH改变与认知及临床指标具有相关性。
英文摘要:
      Objective To investigate the changes of white matter in patients of end-stage renal disease (ESRD) with secondary hyperparathyroidism (SHPT) by using local diffusion homogeneity (LDH). Methods Fifty patients diagnosed as ESRD and underwent hemodialysis were selected. According to whether with SHPT or not, the patients were divided into SHPT group and non-SHPT group (each n=25). The cognitive function was evaluated with Montreal cognitive assessment (MoCA). Then MR plain scan was performed. The LDH value of white matter fiber in the whole brain were compared between 2 groups based on voxel. Results Compared with non-SHPT group, SHPT group showed diffuse and symmetrical LDH decreased area in bilateral cerebral hemispheres, and in the focal right cerebellar hemispheres (all P<0.01). The areas with increased LDH value were mainly in brainstem and cerebellum (P<0.01). In SHPT group, the total score of MoCA was negatively correlated with the level of iPTH (r=-0.525), positively correlated with the level of education (r=0.413). The total score of MoCA was positively correlated with LDH value of left corticospinal tract (r=0.500, all P<0.05), while the level of iPTH was not correlated with the LDH value of different brain regions in SHPT group (all P>0.05). Conclusion LDH value can provide information of the white matter's LDH in ESRD patients with SHPT, and the changes are related to cognition and clinical indicators.
