白癜风患者血清甲状腺自身抗体水平研究(2)
本研究共收集了白癜风患者40例,对照组38例。白癜风患者TPOAb阳性率为25.00%,高于对照组的2.63%(P<0.05)。白癜风患者TGAb阳性率为22.50%,高于对照组的5.26%(P<0.05)。本研究白癜风患者TPOAb和TGAb阳性率低于Kasumagic-Halilovic等[10]报道的结果。女性白癜风患者TPOAb和TGAb阳性率均为20%,明显高于男性(P<0.05)。杨一芬等[11]报道女性白癜风患者血清TPOAb和TGAb血清阳性率均为34.1%,比本研究结果较高。本研究21~30岁年龄段白癜风患者TPOAb和TGAb阳性率高于其他年龄段白癜风患者(P<0.05)。而杨一芬等[11]报道白癜风组11~20岁和21~40岁年龄段高于其他年龄段。Iacovelli等[7]报道白癜风患者中女性伴有自身免疫性甲状腺疾病的概率显著高于男性,本研究与之符合。本研究中,白癜风患者TPOAb和TGAb的阳性率在不同的临床分型、分期中无统计学差异(P>0.05)。
甲状腺自身抗体是甲状腺损害后的继发性免疫反应标志物。本研究追踪报道其中2例白癜风患者确诊为甲状腺功能亢进症,且彩超均示甲状腺体积增大、弥漫性回声改变伴血流丰富,1例白癜风患者确诊为甲状腺功能减退,1例白癜风患者确诊为桥本甲状腺炎,1例患Graves病,且5例患者均为青年女性,年龄在21~30岁。HLA、CTLA-4、PTPN22基因有可能是白癜风和自身免疫性甲状腺疾病共同基因。Buc等[12]研究发现,白癜风与HLA-DRB1、HLA-DQB1、HLA-DPB1位点密切相关,15例HLA-DRB1*0701阳性白癜风患者中有8例伴发桥本甲状腺炎等自身免疫性疾病。Kemp等[13]研究3例白癜风患者TRP-2抗体阳性,均伴发自身免疫性疾病,其中2例患自身免疫性甲状腺功能减退症,1例患Graves病。
国内外大量研究表明白癜风与自身免疫性甲状腺疾病密切相关,本研究进一步验证了两者的相关性。临床医生应该意识到白癜风伴发自身免疫性甲状腺疾病的风险,并留意白癜风患者是否存在甲状腺疾病的症状,便于疾病的早期发现、早期治疗。未来的白癜风诊断治疗中,在白癜风患者中筛查自身免疫性甲状腺疾病,形成一套标准化检测,是非常有必要的。而白癜风与自身免疫性甲状腺疾病的明确相关因素仍需要较大样本量进一步研究。
