摘要
通过测定甲状腺吸 13 1I率鉴别诊断甲亢 13 1I治疗后早发甲低的类型。 63例甲亢 131I治疗后早发甲低的患者 (一过性甲低组 33例 ,永久性甲低组 30例 ) ,在甲状腺素替代治疗前、后 6个月测定甲状腺 3h吸 131I率和血清 TT3、TT4 、TSH浓度。结果表明 :治疗前一过性与永久性甲低组间吸 13 1I率有明显差异 ,TT3、TT4 、TSH浓度无明显差异 ;与对照组相比 ,一过性甲低组治疗前吸 131I率无差异 ,TT3、TT4 和 TSH浓度有明显差异 ,治疗后均无差异 ;永久性甲低组吸 131I率治疗前、后均明显降低。因此早发甲低的患者 ,仅靠 TT3、TT4 、TSH水平难以鉴别甲低类型 ;但根据吸 131I率可准确判断 ,即甲状腺 3h吸 131I率正常 ,可以判断为一过性甲低 ,反之则为永久性甲低。
The 3 h thyroid 131 I uptake rate and the content of serum TT 3,TT 4,TSH are measured in 63 patients of premature hypothyroidism (consiting of 33 provisional pypothyroids and 30 perpetual hypothyroidism) before and after thyroxine substitutes treatment for six moths. The results show that there is obvious difference in 131 I uptake rate compared provisional hypothyroidism with perpetual hypothyroidism, and no difference in the content of serum TT 3,TT 4,TSH before the treatment. Compared with normal conditions, there is no difference in 131 I uptake rate of provisional hypothyroidism, but the 131 I uptake rate of perpetual hypothyroidism has obvious decrease before and after the treatment. Therefore the type of patients who suffer from premature hypothyroidism can be distinguished according to the 131 I uptake rate:if the 3 h thyroid 131 I uptake rate is normal,it is provisional hypothyroidism;if not,it is perpetual hypothyroidism.
