Abstract

OBJECTIVE

To evaluate the diagnostic value of provocative test by insulin combined with clonidine for growth hormone deficiency (GHD) during childhood.

METHODS

Eighty children underwent a provocative test with insulin(0.075U/Kg, intravenous) combined with clonidine (4μg/kg, orally). Among them, 40 children underwent clonidine provocative test, 40 children underwent insulin tolerance test (ITT) in another day.

FINDINGS

The specificity of ITT+clonidine test (74%, 88%) was remarkably higher than that of ITT (48%) or clonidine test (65%). ITT+clonidine test had a better accuracy (75%, 85%) than that of ITT (63%) or clonidine test (73%).

CONCLUSION

We conclude that the combined clonidine+insulin test is a feasible, reliable, convenient, time saving, and safe tool for evaluation of the growth hormone (GH) axes than the clonidine test or ITT.

摘要

目的

评估胰岛素联合可乐定激发试验对儿童生长激素缺乏症(GHD)的诊断价值。

方法

80名儿童接受了胰岛素(0.075U/Kg,静脉注射)联合可乐定(4μg/kg,口服)激发试验。其中,40名儿童接受可乐定激发试验,另外40名儿童在另一天接受胰岛素耐量试验(ITT)。

结果

ITT+可乐定试验的特异性(74%,88%)显著高于ITT(48%)或可乐定试验(65%)。ITT+可乐定试验的准确性(75%,85%)优于ITT(63%)或可乐定试验(73%)。

结论

我们得出结论,与可乐定试验或ITT相比,可乐定+胰岛素联合试验是一种评估生长激素(GH)轴的可行、可靠、方便、省时且安全的工具。
