[摘要]目的探讨131I治疗Graves’病后突眼的转归与TRAb及TGA、TMA的关系,为临床治疗Graves’病后突眼提供理论参考。方法选择伴有突眼的Graves’病患者78例进行131I治疗,在治疗后第3、6、12个月进行随访,检测其TRAb及TGA、TMA浓度。结果治疗前TRAb及TGA、TMA水平高者,治疗后眼病获得改善的可能性较大;而治疗前TRAb及TGA、TMA水平低者,治疗后其活性变化不大,眼病的改善也不明显,差异有显著性。结论TRAb及TGA、TMA水平与突眼的发生和转归关系密切。

Abstract: Objective To discuss the prognosis of goggledgeye caused by Graves' disease after treated with 131I and its association with the levels of TRAb, TGA and TMA in blood. Methods A total of 78 cases of Graves' disease characterized by goggledgeye were treated with 131I, and visited at 3rd, 6th and 12th month after treatment. The blood levels of TRAb, TGA and TMA were tested before treatment and during followgup. Results The patients with high blood levels of TRAb, TGA and TMA before 131I treatment had a higher opportunity to get their eye symptoms improved, vice versa. There was a significant difference between the two kinds of patients. Conclusion The occurrence of goggledgeye and its turnover is closely related to the levels of TRAb, TGA and TMA. Keywords: Graves’ disease; goggledeye; TRAb; TGA; TMA Graves’眼病是一种与自身免疫性甲状腺疾病密切相关的器官特异性自身免疫性疾病,又称甲状腺相关性眼病或自身免疫性甲状腺眼病、浸润性突眼等。本病可严重损害视力和外貌,目前尚无理想的治疗方法,常选用免疫调节治疗、球后放射照射、眼眶减压手术等疗法[1]。本文通过检测2000年1月至2005年6月伴有突眼的Graves’病患者131I治疗前后促甲状腺素受体抗体(TRAb)及甲状腺球蛋白抗体、甲状腺微粒体抗体(TGA、TMA)水平,探讨131I治疗后突眼的转归与这三种抗体水平的关系。
1 资料与方法
1.1 临床资料 本组患者78例,其中男24,女55例,年龄23~56岁,平均35.6岁。所有病例在131I治疗甲状腺功能均有改善或治愈,均未对眼病进行干预治疗。治疗后眼病有好转的为A组,无改变的为B组,恶化的为C组。
1.2方法 所有病例131I治疗前及治疗后3、6、12个月各空腹采血测定TRAb及TGA、TMA。TRAb及TGA、TMA试剂盒由天津协和科技医药有限公司提供。
1.3 结果判断 TRAb值以>12 U/L为阳性, TGA>30%、TMA>20%为阳性,TGA、TMA两项指标中其中一项阳性为TGA、TMA阳性组。突眼的判断采用目前被国际甲状腺协会承认的根据NOSPECS标准演化的眼病指数量化指标。
1.4 统计学处理 检测数据以±s表示,检测结果采用SPSS10.0统计软件包进行t检验、χ2检验。
