慢性荨麻疹患者甲状腺自身抗体检测及自体血清皮肤试验的意义

摘要

Objective To investigate the level of thyroid autoantibodies and autologous serum skin test in patients with chronic urticaria (CU). Methods The subjects were divided into four groups including 100 CU patients, 68 CU combining hyperthyroidism patients, 60 hyperthyroidism patients and 60 controlling cases. By measuring the items such as free thyroxine three and four (FT3,FT4), thyrotropin(TSH), thyroid autoantibodies and autologous serum skin test (ASST), the differences of four groups were compared. Results There were significant differences about positive ratio of thyroid autoantibodies and ASST between CU and controlling group and CU combining hyperthyroidism. Positive ratio of TRAb and ASST in CU combining hyperthyroidism group were higher than those of hyperthyroidism group.The level of sTSH in CU group were lower than controlling group. Conclusion Thyroid autoantibodies may play possible role in pathogenesis of chronic urticaria.%目的 通过检测指标分析慢性荨麻疹和甲状腺功能亢进的关系,探讨甲状腺自身抗体在慢性荨麻疹发病中的作用和自体皮肤血清试验的意义.方法 研究对象分为100例慢性荨麻疹患者组,68例甲亢合并慢性荨麻疹患者组,单纯甲状腺功能亢进患者组和对照组各60例,记录分析四组人群的临床资料,检测游离甲状腺素(FT3、FT4)、高敏促甲状腺素(TSH)、甲状腺自身抗体(TGAb、TPOAb、TRAb),并进行自体血清皮肤试验(ASST),比较各组指标间的差异性.结果 慢性荨麻疹组TGAb、TPOAb、TRAb和ASST阳性率均显著高于对照组；甲亢合并慢性荨麻疹组TGAb、TPOAb、TRAb阳性率均显著高于慢性荨麻疹组,两组ASST阳性率差异有统计学意义；单纯甲亢组TGAb、TPOAb阳性率和甲亢合并慢性荨麻疹组差异无统计学意义,TRAb和ASST阳性率差异有统计学意义；慢性荨麻疹组sTSH水平和对照组差异有统计学意义.结论 甲状腺自身抗体在慢性荨麻疹发病中可能起一定的作用,ASST在甲亢合并慢性荨麻疹患者中阳性率更高.
