摘要:

目的 探讨慢性阻塞性肺疾病(COPD)合并感染患者甲状腺激素水平的变化及其与低T3综合征的关系。方法 选取 COPD合并感染患者58例(COPD合并感染组)、体检健康者40名(正常对照组),检测所有患者感染控制前后和正常对照者的血清甲状腺激素[促甲状腺激素(TSH)、总三碘甲状腺原氨酸(TT3)、游离三碘甲状腺原氨酸(FT3)、总甲状腺素(TT4)、游离甲状腺素(FT4)]水平,基于参考区间和参考变化值(RCV)评估COPD合并感染患者的低T3综合征发病率。结果 COPD合并感染组抗感染治疗前TT3、FT3水平显著低于正常对照组(P<0.05);治疗后TT3、TSH 水平显著高于治疗前(P<0.05),但TT3仍低于正常对照组(P<0.05);TT4、FT4各组间差异均无统计学意义(P>0.05)。基于参考区间进行判定,58例COPD合并感染患者感染控制前有29例(50.0%)存在低T3综合征,感染控制后有21例(36.2%)存在低T3综合征。基于RCV进行判定,58例患者中有12例(20.8%)存在低T3综合征。基于RCV判定的低T3综合征发病率显著低于基于参考区间判定的发病率(P<0.05)。结论 COPD合并感染患者中低T3综合征的发病率较高,临床应监测甲状腺激素水平,同时重视应用RCV进行检测结果的解读。

Abstract:

Objective To investigate the changes of thyroid hormones in patients with chronic obstructive pulmonary disease(COPD) and infection and the correlation with low triiodothyronine(T3) syndrome. Methods Totally,58 patients with COPD and infection were enrolled. The results of thyroid hormones,including thyroid-stimulating hormone(TSH),total triiodothyronine(TT3),free triiodothyronine(FT3),total thyroxine(TT4) and free thyroxine(FT4),were collected. The rate of low T3 syndrome in patients with COPD and infection was evaluated based on the reference change value(RCV) and reference intervals. Results Compared with control group,COPD patients with infection showed lower TT3 and FT3 levels(P<0.05). TT3 and TSH after treatment were higher than those before treatment(P<0.05),which TT3 was still lower than that in control group(P<0.05). There was no statistical significance for TT4 and FT4 among the groups(P>0.05). Based on the reference intervals,29 of 58 COPD patients with infection were diagnosed as low T3 syndrome before infection (50.0%). After infection control,21 cases had low T3 syndrome (36.2%). Based on the RCV,12 of 58 patients had low T3 syndrome (20.8%). The incidence rate of low T3 syndrome based on the RCV was lower than that based on the reference intervals (P<0.05). Conclusions The patients with COPD and infection has high low T3 syndrome rate ,and the levels of thyroid hormones should be monitored. The results based on the RCV should be good choice for clinicians to recognize low T3 syndrome cases.
