摘要
目的探讨25.羟维生素D[25(OH)D]水平对自身免疫性甲状腺疾病(AITD)患者甲状腺激素及自身抗体的影响。方法AITD患者48例.其中Graves病17例(GD组),桥本甲状腺炎(HT)31例(HT组)。另选择健康者19例为对照组。检测血清25(OH)D、游离三碘甲状腺原氨酸(FT3)、游离甲状腺素(FT4)、总三碘甲状腺原氨酸(TT3)、总甲状腺素(TT4)、促甲状腺激素(TSH)、甲状腺过氧化物酶抗体(TPOAb)及促甲状腺素受体抗体(TRAb)水平。分析AITD患者25(OH)D水平与FT3、FT4、TT3、TT4、TSH、TPOAb、TRAb水平的相关性。结果与对照组比较,GD组、HT组患者25(OH)D水平明显降低,差异有统计学意义(P〈0.05)。GD组血清中25(OH)D水平与TPOAb(r=-0.9261,P〈0.01)水平呈显著负相关,与FT3、FT4、TT3、TT4、TSH、TRAb水平无明显相关性。HT组血清中25(OH)D水平与FT4(r=-0.8632,P〈0.01)、TPOAb(r=-0.4222,P〈0.05)、TRAb(r=.0.9561,P〈0.01)水平呈显著负相关,与FT3、TT3、TT4、TSH水平无明显相关性。结论AITD患者25(OH)D水平不足,其可能在甲状腺自身免疫反应的发生发展中起着重要作用。
Objective To explore the effect of serum 25-hydroxyvitamin D[ 25 ( OH ) D ] level on thyroid hormones and its auto-antibody in patients with autoimmune thyroid disease ( AITD ) and study the correlation among them.Methods 48 cases AITD outpatients ( GD group and HT group ) and 19 cases healthy subjects ( control group ) were selected from Aug. 2011 to Feb 2013. The levels of serum 25 ( OH ) D, free triiodothyronine ( FT3 ) , free thyroxine ( FT4 ) , total triiodothyronine ( TT3 ) , total thyroxine ( TT4 ) , thyroid-stimulating hormone ( TSH ) , thyroid peroxidase antibody ( TPOAb ) , thyrotrophin receptor antibody ( TRAb ) were detected in GD group and HT group as well as control group.The correlation between serum 25 ( OH ) D levels and the levels of FT3, FT4, TT3, TT4, TSH, TPOAb, TRAb were analyzed.Results Compared with the control group, the levels of 25 ( OH ) D in GD group and HT group were decreased, there were statistically significant difference ( P〈0.05 ) . In GD group, the levels of 25 ( OH ) D and TPOAb ( r=--0.9261, P〈0.01 ) were negatively related, but the levels of 25 ( OH ) D and FT3, FT4, TT3, TT4, TSH, TRAb had no obvious relation. In HT group, the levels of 25 ( OH ) D and FT4 ( r=-0.8632, P〈0.01 ) , TPOAb ( r=-0.4222, P〈0.05 ) , TRAb ( r=--0.9561, P〈0.01 ) were negatively related, and the levels of 25 ( OH ) D and FT3, TT3, TT4, TSI-I had no obvious relation. Conclusion Vitamin D deficiency universally exists in AITD patients, and it may play an important role in the pathogenesis of AITD.
