OBJECTIVE Brain iron deposition in hemodialysis (HD) patients increases over time. Iron deficiency in gray matter nuclei has been reported to lead to idiopathic restless legs syndrome (RLS) symptoms. Regardless of unpleasant RLS sensations, the patterns of iron deposition between hemodialysis patients with RLS (HD-RLS) and hemodialysis patients without RLS (HD-nRLS) are still unclear. To evaluate the differences in iron deposition patterns between HD-RLS and HD-nRLS patients, we utilized quantitative susceptibility mapping (QSM). METHODS In sum, 24 HD-RLS patients, 25 HD-nRLS patients and 30 age- and sex-matched healthy controls (HCs) were enrolled. The QSM was used to assess susceptibility values of the regions of interest (ROIs), including the caudate nucleus (CN), putamen (PUT), globus pallidus (GP), thalamus (THA), substantia nigra (SN), red nucleus (RN) and dentate nucleus (DN). RESULTS HD duration was significantly longer in HD-RLS patients than in HD-nRLS patients (P < 0.05). The susceptibility of HD-RLS and HD-nRLS patients in PUT was higher than that in HCs (P < 0.05), illustrating elevated iron content in the nucleus. Compared with HD-nRLS patients, HD-RLS patients demonstrated reduced susceptibility in CN and PUT (both P < 0.05). Compared with HCs, HD-RLS patients displayed decreased susceptibility in DN (P < 0.05). CONCLUSIONS Different iron deposition patterns between HD-RLS and HD-nRLS patients in PUT and DN, which further support disturbed sensory processing in RLS, may be involved in RLS pathogenesis in HD patients.

有和没有腿不安定综合征的血液透析患者中​​不同的铁沉积模式:定量药敏图研究。

目的血液透析(HD)患者的脑铁沉积随时间增加。据报道,灰质核铁缺乏症会导致特发性躁动腿综合征(RLS)症状。不管令人不愉快的RLS感觉如何,尚不清楚带有RLS的血液透析患者(HD-RLS)和不带有RLS的血液透析患者(HD-nRLS)之间的铁沉积模式。为了评估HD-RLS和HD-nRLS患者之间铁沉积模式的差异,我们利用了定量磁化图(QSM)。方法总共纳入了24例HD-RLS患者,25例HD-nRLS患者以及30例年龄和性别匹配的健康对照(HCs)。QSM用于评估感兴趣区域(ROI)的敏感性值,包括尾状核(CN),壳壳(PUT),苍白球(GP),丘脑(THA),黑质(SN),红色核(RN)和齿状核(DN)。结果HD-RLS患者的HD持续时间明显长于HD-nRLS患者(P <0.05)。HD-RLS和HD-nRLS患者在PUT中的敏感性高于HCs(P <0.05),这说明细胞核中铁含量升高。与HD-nRLS患者相比,HD-RLS患者对CN和PUT的敏感性降低(均P <0.05)。与HCs相比,HD-RLS患者的DN易感性降低(P <0.05)。结论HD-RLS和HD-nRLS患者在PUT和DN中存在不同的铁沉积模式,这进一步支持了RLS的感觉处理紊乱,可能与HD患者的RLS发病有关。HD-RLS和HD-nRLS患者在PUT中的敏感性高于HCs(P <0.05),这说明细胞核中铁含量升高。与HD-nRLS患者相比,HD-RLS患者对CN和PUT的敏感性降低(均P <0.05)。与HCs相比,HD-RLS患者的DN易感性降低(P <0.05)。结论HD-RLS和HD-nRLS患者在PUT和DN中存在不同的铁沉积模式,这进一步支持了RLS的感觉处理紊乱,可能与HD患者的RLS发病有关。HD-RLS和HD-nRLS患者在PUT中的敏感性高于HCs(P <0.05),这说明细胞核中铁含量升高。与HD-nRLS患者相比,HD-RLS患者对CN和PUT的敏感性降低(均P <0.05)。与HCs相比,HD-RLS患者的DN易感性降低(P <0.05)。结论HD-RLS和HD-nRLS患者在PUT和DN中存在不同的铁沉积模式,这进一步支持了RLS的感觉处理紊乱,可能与HD患者的RLS发病有关。HD-RLS患者的DN敏感性降低(P <0.05)。结论HD-RLS和HD-nRLS患者在PUT和DN中存在不同的铁沉积模式,这进一步支持了RLS的感觉处理紊乱,可能与HD患者的RLS发病有关。HD-RLS患者的DN敏感性降低(P <0.05)。结论HD-RLS和HD-nRLS患者在PUT和DN中存在不同的铁沉积模式,这进一步支持了RLS的感觉处理紊乱,可能与HD患者的RLS发病有关。
