CLIN CHEM LAB MED:间接法检测地中海成人血清促甲状腺素(TSH)的参考区间及其与年龄和性别的关系

2019-11-17 MedSci MedSci原创

血清促甲状腺激素(TSH)浓度是诊断算法中的一线检测指标。估计TSH参考区间(RIs)目前仍有争议,因为亚临床疾病的高发病率使难以界定真正健康的受试者。本研究的目的是估计健康受试者的TSH RIs,并评估年龄和性别对TSH浓度的影响。

血清促甲状腺激素(TSH)浓度是诊断算法中的一线检测指标。估计TSH参考区间(RIs)目前仍有争议,因为亚临床疾病的高发病率使难以界定真正健康的受试者。本研究的目的是估计健康受试者的TSH RIs,并评估年龄和性别对TSH浓度的影响。

20127月至20184月期间,巴勒莫大学-医院检验医学部收集了大量的TSH数据。排除15岁以下的个体、重复TSH检测的受试者以及游离甲状腺素(fT4)、游离三碘甲状腺氨酸(fT3)或抗甲状腺过氧化物酶抗体异常的受试者后,用Arzideh间接法估计常见和性别特异性RIs。评价年龄和性别对TSH值的综合影响。

在被选择的个体(n = 22602)RIs分别为0.18-3.54 mIU/L(一般)0.19-3.23 mIU/L(男性)0.18-3.94 mIU/L(女性)。女性TSH中位数明显高于男性(1.461.39 mIU/L;p < 0.0001)。无论男性还是女性,TSH中值均随年龄下降;然而,尽管在60岁之前男性和女性都表现出相似的趋势,但之后女性的TSH持续高于男性。因此,统计分析显示性别与年龄之间存在显著的交互作用(p = 0.001),提示年龄对TSH的影响在性别间存在差异。研究表明,间接方法,并结合适当的数据过滤,可能会有益于定义TSH RIs
