摘  要:目的探讨Graves病(GD)、GD合并桥本甲状腺炎(GH)及桥本甲状腺毒症(HT)患者血清中甲状腺球蛋白抗体(瞻Ab)和甲状腺过氧化物酶抗体(TPOAb)IgG亚型的分布及意义。方法收集2010年1月至2013年5月在北京大学第一医院、北京市海淀医院、中日友好医院和民航总医院内分泌科通过甲状腺细针穿刺细胞病理学诊断的GD(33例)、GH(31例)及HT(18例)患者的血清,采用ELISA法检测TgAb、TPOAb总lgG和各IgG亚型的百分结合率,比较各亚型的阳性率及阳性亚型的相对含量。结果TRAb的水平在GD、GH、HT组依次为21.80(7.53,40.00)U/L、7.30(3.10,25.40)U/L、4.90(1.69,16.43)U/L,GD组明显高于GH组(P=0.000)和FIT组(P=0.003),差异均有统计学意义,但三组的TRAb水平有重叠。三组间TgAb和TPOAb总IgG的水平差异均无统计学意义。TgAbIgG3亚型在HT组的阳性率(66.7%)有高于GH组(35.5%)和GD组(36.4%)的趋势(P=0.066)。GD、GH、HT组TgAbIgG2阳性患者的相对含量分别为0.59(0.34,0.94)、0.31(0.23,0.34)、0.32(0.24,0.83),GD组高于GH组(P=0.009),差异有统计学意义,GD组高于HT组(P:0.167),差异无统计学意义。GD、GH、HT组TgAblgG4阳性患者的相对含量分别为0.57(0.28,0.97)、0.26(0.09,0.48)、0.33(0.10,0.65),GD组高于GH组和HT组(P=0.005、0.041),差异均有统计学意义。TPOAb各IgG亚型的阳性率在三组间差异无统计学意义。GD、GH、HT组TPOAbIgG2阳性患者的相对含量分别为0.39±0.04、0.29±0.13、0.26±0.02,GD组高于HT组(P=0.002),差异有统计学意义,GD组高于GH组(P=0.104),差异无统计学意义。结论血清中TgAb和TPOAbIgG2或TgAblgG4亚型相对含量高提示Graves病的可能性大,利用TgAb和TPOAbIgG亚型相对含量的差异可能为临�Objective To evaluate the distribution of IgG subclasses of TgAb and TPOAb in sera from patients with Graves' disease (GD), Graves' disease plus Hashimoto's thyroiditis (GH) and Hashimoto's thyrotoxicosis. Methods Patients with GD ( n = 33 ), GH ( n = 31 ) or Hashimoto' s thyrotoxicosis (n = 18 )diagnosed by fine needle aspiration cytology at Department of Endocrinology of Peking University First Hospital, Beijing Haidian Hospital, China-Japan Friendship Hospital and Civil Aviation General Hospital during the period from January 2010 to May 2013 were enrolled. All of them had TgAb and TPOAb. The total serum IgG and IgG subclasses of TgAb and TPOAb were detected by antigen-specific enzyme-linked immunosorbent assay (ELISA). The prevalence and relative amount of lgG subclasses were calculated and compared among three groups. Results The levels of TRAb in GD group (21.80 (7.53, 40) U/L) were significantly higher than those in GH ( 7.30 ( 3. 10, 25.40 ) U/L) ( P = 0. 000 ) and Hashimoto's thyrotoxicosis groups ( 4. 90 ( 1.69, 16. 43 ) U/L) ( P = 0. 003 ). And no significant differences were found in the levels of TgAb and TPOAb. The prevalence of TgAb IgG3 subclass in Hashimoto's thyrotoxieosis group ( 66.7% ) was higher than GD group ( 35.5% ) and GH group ( 36.4% ) and the difference was close to significance ( P = 0. 066). There were significant differences of relative amount of TgAb IgG2 and TgAb IgG4 among three groups ( P = 0.039 and O. 013 ) , and GD patients had higher relative amounts of TgAb IgG2 ( 0. 59 ( 0. 34, 0. 94 ) ) and TgAb IgC,4 ( 0. 57 ( 0. 28, 0. 97 ) ) than GH patients (TgAb IgG2, 0. 31(0. 23, 0. 34); TgAb IgG4, 0.26(0.09, 0.48)) or patients with Hashimoto's thyrotoxicosis (TgAb IgG2, 0. 32(0. 24, 0. 83) ; TgAb IgG4, 0. 33(0. 10, 0. 65) ) (for TgAb IgG2, P = 0. 009 and 0. 167; for TgAb IgG4, P =0. 005 and 0. 041 respectively). No significant difference was found
