摘要
目的:研究肿瘤坏死因子α基因多态性与吉兰-巴雷综合征( GBS)的两种主要亚型-急性炎性脱髓鞘性多发神经根神经病(AIDP)和急性运动轴索型神经病(AMAN)的易感性和预后的关系。方法对我院在4 年内收治的吉兰-巴雷综合征患者进行电生理标准分组,在疾病高峰期和发病1 年后随访时进行Hughes神经功能评分;采用聚合酶链式反应-限制性片段长度多态性(PCR-RFLP)技术对41 例AIDP 患者、52 例AMAN 患者和98 例健康人进行TNFα基因多态性分析。结果 AIDP 组基因型分布和等位基因频率与对照组相比,没有显著差别;AMAN 组TNFα基因型分布与对照组有差别,TNFα2 等位基因频率(17.3%)明显高于对照组(5.1%); GBS 重症型患者(Hughes 评分4~6)基因型分布与对照组有差别,TNFα2 等位基因频率明显高于对照组(16.4% vs.5.1%); GBS 预后较差患者(Hughes 评分>2)TNFα2 等位基因频率明显高于对照组(17.5% vs.5.1%)。结论 TNFα2 等位基因与AMAN 的易患性有关,携带有TNFα2 等位基因患者更倾向有较严重的疾病病程且预后较差。
Objective To study the relations between the susceptibility to AIDP and AMAN , two subsets of GBS, and the frequencies of TNFαgene polymorpsim .Methods The patients with GBS were recruited between 2008 and 2011 and retrospectively reviewed .The gene polymorphism of TNFαwas detected by means of polymerase chain reaction ( PCR) with restriction fragment length polymorphisms ( RFLP ) techniques .Results TNFα2 frequency increase significantly in AMAN group,severe group and poor outcome group than controls (17.3%,16.4%,17.5%vs. 5.1%). Conclusion AMAN and AIDP is the main subtype of GBS in northeastern China .AMAN susceptibility is associated with TNFα2, and patients with the genetype of TNFα2 likely have more severe pathogenesis and poor outcomes .
