J Clin Endo&Met:Tg可作为成人体内碘营养状态的血液学标志

2016-02-23 MedSci MedSci原创

评估碘营养状况,尿碘浓度提高与血Tg浓度降低相关,表明血Tg浓度可作为成人体内碘营养状况评估的有用的生物标志物。

研究目标

已有研究发现儿童体内甲状腺球蛋白(Tgthyroglobulin)和尿碘浓度(UICurinary iodine concentration )之间呈负相关关系,Tg可作为儿童体内碘状态的可靠血液学标志。但是目前Tg是否可以作为成人体内碘状态的血液学标志仍不清楚。基于此,本研究重点探讨Tg对成人体内碘状态的效能。

研究设计

选取新西兰Dunedin的112例年龄在18-40岁的轻度缺碘成人为参与者,采用随机、双盲、安慰剂对照的临床试验。参与者每天服用含150μg碘的碘酸钾口服液或安慰剂,持续24周。在基线和24周时检查参与者尿碘浓度、血清TSHFT4。在基线和81624周检查参与者Tg浓度。

结果

在基线,参与者尿碘浓度总体中位数是65μg/L ,表明大部分参与者处于轻度碘缺乏状态(尿碘浓度范围 5099 μ g/L)。基线检测,参与者Tg总体中位数是16.6 μg/L,第24周时,补充碘组与安慰剂组参与者之间Tg浓度存在差异。TSGFT4处于正常范围。第24周,补充碘组(168 μg/L)与安慰剂组(79μg/L)中位尿碘浓度存在显著差异(P<0.001)。与安慰剂组相比,补充碘组参与者在第8(P=0.045) 、第16(P<0.001) 和第24(P<0.001) Tg浓度分别降低了12% 20%27% 。两组间TSHFT4浓度没有显著差异。

结论

评估碘营养状况,尿碘浓度提高与血Tg浓度降低相关,表明血Tg浓度可作为成人体内碘营养状况评估的有用生物标志物。
