摘要：

目的 探讨白癜风患者甲状腺球蛋白抗体（ATG）和甲状腺过氧化物酶抗体（ATPO）检测的临床意义。方法 采用化学发光法检测87例白癜风患者和年龄、性别相匹配的90例正常人对照组血清ATG、ATPO、游离T3、游离T4和促甲状腺激素（TSH）水平，并按年龄、性别分层进行比较。结果 白癜风组的血清ATG和ATPO阳性率以及TSH平均浓度显著高于正常人对照组，且ATG和ATPO阳性者均为寻常型白癜风。白癜风组11 ～ 20岁和21 ～ 40岁年龄段ATG和ATPO阳性率显著高于同年龄段的正常人对照组，且白癜风组女性ATG和ATPO阳性率均为34.1%，显著高于正常人对照组女性（8.5%和10.6%），χ2值分别为8.90和7.29，P值 < 0.01和0.05；在白癜风患者中，11 ～ 20岁年龄段ATG和ATPO阳性率最高，达53.3%，其次为21 ~ 40岁年龄段，为34.5%；20例ATG和ATPO阳性的白癜风患者中，14例（70%）随后诊断为自身免疫性甲状腺疾病, 显著高于ATG和ATPO阳性的正常人对照组发病率（16.7%），χ2 = 5.4，P < 0.05。结论 ATG和ATPO出现在青少年女性寻常型白癜风患者中，并与自身免疫性甲状腺疾病的发生相关。

Abstract:

Objective To investigate the clinical significance of thyroglobulin antibody （ATG） and thyroid peroxidase antibody （ATPO） in patients with vitiligo. Methods Venous blood samples were obtained from 87 patients with vitiligo and 90 age- and sex-matched normal human controls. Chemiluminescence was applied to measure the serum levels of ATG, ATPO, free triiodothyronine, free tetraiodothyronine and thyroid stimulating hormone （TSH）. Results There was a significant increase in the positivity rates of ATG （23.0% vs 6.7%, P < 0.01） and ATPO （24.1% vs 7.8%, P < 0.01） as well as the serum level of TSH （3.4 ± 2.4 vs 2.4 ± 1.2 pmol/L, P < 0.05） in the patients with vitiligo compared with the normal human controls. It is worth mentioning that all patients positive for ATG or ATPO were diagnosed with vitiligo vulgaris. The positivity rates of ATG and ATPO in patients with vitiligo aged from 11 to 20 years and 21 to 40 years were significantly higher than those in age-matched normal controls （all P < 0.05）. Also, female patients had a higher positivity rate of ATG and ATPO than female controls did （34.1% vs 8.5%, χ2 = 8.90, P < 0.01; 34.1% vs 10.6%, χ2 = 7.29, P < 0.05）. The highest positivity rates of both ATG and ATPO were 53.3%, which were observed in vitiligo patients aged from 11 to 20 years, followed by patients from 21 to 40 years （ATG 34.5%, ATPO 34.5%）. In patients with vitiligo positive for both ATG and ATPO, the occurrence of autoimmune thyroid disease was 70% （14/20）, significantly higher than that in ATG- and ATPO- positive healthy controls （16.7%, χ2 = 5.4, P < 0.05）. Conclusions ATG and ATPO were observed in young female patients with vitiligo vulgaris, and they may be associated with the development of autoimmune thyroid diseases.
