摘要
目的探讨皮质醇增多症患者甲状腺功能的临床特征。方法回顾性分析2009年1月至2014年12月于中国医科大学附属第一医院就诊的54例皮质醇增多症患者的临床资料,其中27例接受手术治疗。检测所有患者治疗前的游离三碘甲状腺原氨酸(FT3)、游离甲状腺素(FT4)、促甲状腺激素(TSH)水平并分析甲状腺功能改变的特点。经手术治疗的27例患者中,有14例在术后随访中复查早晨8点的血皮质醇、促肾上腺皮质激素(ACTH)、FT3、FT4、TSH,分析血皮质醇水平对甲状腺功能的影响。结果54例皮质醇增多症患者中,甲状腺功能异常者占37.0%(20/54),FT3、FT4、TSH降低者分别占16.7%(9/54)、13.0%(7/54)、24.1%(13/54),均低于正常值下限。14例经手术治疗的皮质醇增多症患者,术后血皮质醇及ACTH水平下降,得到有效控制,与术前比较差异均有统计学意义[59.8(34.9,163.0)nmol/L比776.2(532.2,1030.2)nmol/L,1.8(1.0,24.3)ng/L比50.4(1.0,78.6)ng/L](P〈0.05);术后FT3、FT4、TSH水平升高(均低于正常值上限),FT3及FT4与术前比较差异有统计学意义[(4.2±1.1)pmol/L比(3.2±0.7)pmol/L,(15.4±2.4)pmo]/L比(11.6±2.7)pmol/L](P〈0.05)。结论皮质醇增多症患者血皮质醇水平升高使下丘脑-垂体-甲状腺轴的调节机制减弱,甲状腺功能受损,出现甲状腺激素水平和TSH水平同时减低,在手术治疗后甲状腺功能得到不同程度的改善。
Objective To analyze the clinical characteristics of thyroid function in patients with hypercor- tisolism. Methods Clinical data of 54 patients with hypercortisolism from January 2009 to December 2014 in The First Affiliated Hospital of China Medical University were retrospectively analyzed. Operations were performed in 27 patients. Serum levels of free triiodothyronine( FT3 ), free thyroxine( FT4 ), thyroid stimulating hormone(TSH) were analyzed. Fasting cortisol, adrenocorticotropic hormone (ACTH), FT3, FT4 and TSH were tested in 14 patients who had operationto analyze the effect of cortisol variation on thyroid function. Results In 54 cases of hypercortisolism, abnormal thyroid function accounted for 37.0% (20/54) ; reduction of FT3 , FT4 , TSH accoun- ted for 16. 7% (9/54), 13.0% (7/54), 24. 1% ( 13/54), respectively. Levels of cortisol and ACTH decreased in 14 cases after operation and the differences were significant compared to those before operation [ 59. 8 ( 34. 9, 163.0) nmol/L vs 776. 2 ( 532. 2, 1 030. 2 ) nmol/L, 1.8 ( 1.0, 24. 3 ) ng/L vs 50.4 ( 1.0, 78. 6 ) ng/L] ( P 〈 0. 05 ) ; levels of FT3 , FT4 and TSH increased in 14 cases after operation ; the differences of FT3 and FT4 were sta- tistically significantly compared to those before operation [ (4. 2 ± 1.1 ) pmol/L vs ( 3.2 ± 0. 7 ) pmol/L, ( 15.4 ± 2. 4) pmol/L vs ( 11.6 ± 2. 7 ) pmol/L ]( P 〈 0. 05 ). Conclusion Elevated cortisol weakens the regulation function of hypothalamic-pituitary-thyroid axis, which cause thyroid function impariment with decrease of thyroid hormone and TSH in hypercortisolism patients ; thyroid function can be improved in different degree after operation.
