【摘要】 目的:探讨肝硬化对血清甲状腺激素水平的影响及其临床意义。方法:用CLIA检测66例肝硬化患者TT3、TT4、rT3、FT3、FT4、TSH的含量,并与对照组40例上述指标对照,肝硬化患者按Child—Pugh方法分级为A、B、C三级,各级之间进行对比。结果:肝硬化组患者入院时TT3、FT3、TT4降低,rT3明显升高,对照组TT3、FT3、TT4、rT3正常,2组比较差异具有统计学意义(P<0.01),肝硬化组Child—Pugh分级A、B、C三级血清甲状腺激素水平相互比较亦有显著差异(P<0.05)。结论:测定甲状腺激素水平可以作为评估肝硬化的严重程度及预后等具有重要的参考价值。

Abstract Objective:To probe into the influence of cirrhosis on the thyroid hormone in serum and its clinical significance.Methods:With the method of radioimmunoassay,66 cirrhosis cases’contents in serum of triiodothyronine(TT3),thyroid hormone(TT4),rT3,free triiodothyronine(FT3),free thyroid hormone(FT4) and thyrotropin hormone(TSH) were checked,then compared with the contents of 40 cases in the controls.The cirrhosis patients were divided into A,B,C grade according to the method of Child-Pugh,the level of thyroid hormone in serum of the grades were compared.Results:The cirrhosis patients’TT3、FT3、TT4 decreased while rT3 obviously rised when admitting to hospital,in the controls,TT3、FT3、TT4、rT3 were normal.The differences between the two groups were significant(P<0.01).In cirrhosis cases’,the difference of thyroid hormone level in serum among different grades had significance,too.Conclusion:The thyroid hormone level can be an index of cirrhosis patient’s severity and prognosis.

肝脏是甲状腺激素储存和代谢主要场所之一,是总甲状腺素(TT4)脱碘形成总三碘甲腺原氨酸(TT3)的主要部位,TT 4主要在肝脏蓄积,并被激活或灭活。肝硬化常有甲状腺激素代谢紊乱,血清中TT3、TT4、游离三碘甲腺原氨酸T3(FT3)、游离甲状腺素T4(FT4)、反三碘甲腺原氨酸T3(rT3)、促甲状腺激素(TSH)的浓度随肝硬化的类型及严重程度而增高或降低。本文通过对66例肝硬化患者血清甲状腺激素的放免检测,探讨了TT3、TT4、FT3、FT4、rT3、TSH水平的变化。
资料与方法
2004年12月~2009年6月收治肝硬化患者66例(肝硬化组),其中男47例,女19例,年龄26~72岁,平均54.2岁。诊断均符合2000年9月西安学术会议讨论修订的诊断标准[1],肝硬化组按Child-Pugh分级[2],其中A级11例,B级18例,C级37例,本组患者均排除垂体、甲状腺、恶性肿瘤、糖尿病、肾病综合征等影响甲状腺激素代谢的疾病,未服影响甲状腺素代谢的药物。对照组40例,男23例,女l
