摘要
目的探讨甲状腺激素替代治疗对老年原发性亚临床型甲状腺功能减退症(SCH)患者认知功能的影响。方法选择临床确诊的老年SCH患者120例,采用左旋甲状腺素替代治疗6个月,对治疗前、后的甲状腺功能及认知功能损伤进行评估。结果SCH患者激素替代治疗6个月后,促甲状腺激素(TSH)水平明显下降,与治疗前比较差异有统计学意义[(15.21±1.78)mU/L和(3.46±0.37)mU/L,t=6.417,P=0.0083];甲状腺激素替代治疗6个月后,SCH患者在神经心理学实验中的画钟表试验、图像记忆、摆积木、复杂图形复制、复杂图形回忆及图形延迟回忆、词表延迟回忆、连线A、词表学习第1次、词表延迟回忆、词语再认、数字顺背、数字倒背、词语流畅性、数字符号实验均较治疗前有明显提高[(8.74±1.08)和(9.63±1.32),(6.14±1.03)和(8.47±1.38),(30.36±7.27)和(36.42±8.54),(13.71±1.05)和(14.87±1.38),(11.21±1.13)和(13.56±1.34),(11.36±1.27)和(13.06±1.47),(5.27±0.84)和(6.54±1.03),(63.13±12.09)和(54.63±10.07),(3.64±1.07)和(4.91±1.32),(5.27±0.84)和(6.54±1.03),(8.52±1.16)和(9.83±0.96),(8.01±0.83)和(8.94±1.08),(4.04±0.57)和(5.37±0.75),(11.21±1.03)和(13.43±1.23),(33.46±8.72)和(38.06±9.58);t值分别为13.907、11.027、12.093、16.374、10.361、11.536、8.794、—10.617、9.601、8.794、17,814、7.913、12.415、13.992、10.128,P值分别为0.028、0.039、0.036、0.029、0.042、0.040、0.048、0.042、0.045、0.048、0.027、0.048、0.038、0.032、0.041]。结论甲状腺素替代治疗可以改善老年SCH患者的轻度认知功能损伤。
Objective To investigate the effect of levothyrocine-thyroxine 4 (L-T4) replacement therapy on cognitive status in elderly patients with subclinical hypothyroidism (SCH). Methods One hundred and twenty elderly patients with SCH were selected and treated with thyroid hormone replacement therapy for 6 months. The thyroid functions and cognitive impairments were tested for all the subjects before and after the therapy. Results After 6 months of thyroid hormone replacement therapy, the level of thyrotropic hormone was significantly lower than that of before herapy( ( 15.21 ± 1.78) mU/L vs. (3.46 ± 0. 37) mU/L, t = 6. 417, P = 0. 0083));The neuropsychological test performance in patients with hypothyroidism showed statistically significant improvements in clock drawing test, iconic memory, block design, complex graphics recall and delayed recall,trail making A, word list learningl, recall and recognize, forward and backward digital span, verbal fluency, and digital symbol from WAIS-RC ( ( 8.74 ± 1.08 ) vs. ( 9. 63 ±1.32 ), ( 6. 14 ± 1.03 ) vs. ( 8.47 ±1.38),(30.36 ± 7.27) vs. (36.42 ± 8.54), (13.71 ±1.05) vs. (14.87 ± 1.38), (11.21 ± 1.13) vs. (13.56 ±1.34),(11.36 ±1.27)vs. (13.06 ±1.47), (5.27 ±0.84) vs. (6.54 ±1.03), (63. 13 ±2.09) vs. (54. 63 ±10. 07), (3.64 ± 1.07) vs. (4. 91 ±1.32), (5.27 ±0. 84)vs. (6. 54 ±1.03 ), (8.52 ±1.16) vs. (9.83 ±0.96),(8.01 ±0. 83) vs. (8.94 ± 1.08), (4.04 ±0.57) vs. (5.37 ±0.75), (11.21 ±1.03) vs. ( 13.43 ±1.23 ), ( 33.46 ±8.72) vs. ( 38.06 ±9. 58 ), t = 13. 907,11. 027,12. 093,16. 374,10. 361,11. 536, 8.794, - 10. 617,9. 601,8. 794, 17. 814, 7. 913, 12. 415, 13. 992, 10. 128 respectively, P = 0. 028,0. 039, 0. 036,0. 029,0. 042,0. 040,0. 048,0. 042,0. 045,0. 048,0. 027,0. 048,0. 038,0. 032,0. 041 respectively).
