JAMA:亚临床甲状腺功能减退症 全新Meta分析不支持常规使用甲状腺激素

2018-11-28 吴星 环球医学

亚临床甲状腺功能减退症患者使用甲状腺激素治疗的获益未知。近期大型随机临床试验的新证据需要更新之前的Meta分析。2018年10月,发表在《JAMA》的一项Meta分析调查了,亚临床甲状腺功能减退症患者甲状腺激素治疗与生活质量和甲状腺相关症状的相关性。

临床甲状腺功能减退症患者使用甲状腺激素治疗的获益未知。近期大型随机临床试验的新证据需要更新之前的Meta分析。2018年10月,发表在《JAMA》的一项Meta分析调查了,亚临床甲状腺功能减退症患者甲状腺激素治疗与生活质量和甲状腺相关症状的相关性。

目的:旨在进行一项Meta分析,确定甲状腺激素治疗与亚临床甲状腺功能减退症成年患者生活质量和甲状腺相关症状的相关性。

数据来源:Pubmed、Embase、ClinicalTrials.gov、科学网、Cochrane图书馆、CENTRAL、Emcare、Academic Search Premier数据库,从建库到2018年7月4日。

研究选择:比较亚临床甲状腺功能减退症非妊娠期成年患者甲状腺激素治疗vs安慰剂或不治疗的随机临床试验。两名审查者基于检索出的所有研究的标题和摘要独立评估了入组标准。两名审查者在评估全文后,对第一阶段未排除的研究独立评估了入组标准。

数据采集和分析:两名独立审查者提取了数据,评估了偏倚风险(Cochrane偏倚风险工具)和证据质量(GRADE工具)。对于数据合并,临床评分的差异(如生活质量)转化为标准均数差(SMD;阳性值表明甲状腺激素治疗具有获益;0.2、0.5和0.8分别对应于小、中和大效应)。应用随机效应模型进行Meta分析。

主要结局和测量:最短随访3个月后的综合生活质量和甲状腺相关症状。

结果:总体来说,21/3088篇初始鉴别出来的文献满足入组标准,总共包含随机分组的2192名患者。治疗后(范围,3~18个月),与安慰剂相比,甲状腺激素治疗与促甲状腺激素平均值降至正常参考范围内相关(范围,0.5~3.7 mIU/L vs 4.6~14.7 mIU/L),但是与综合生活质量(796人;SMD,-0.11;95% CI,-0.25~0.03;I2=66.7%)或甲状腺相关症状(858人;SMD,0.01;95% CI,-0.12~0.14;I2=0.0%)的获益不相关。总体来说,偏倚风险为低风险,GRADE工具评估出的证据质量为中等至高。

结论和意义:亚临床甲状腺功能减退症非妊娠期成年患者中,甲状腺激素治疗与综合生活质量或甲状腺相关症状的改善不相关。这些结果不支持亚临床甲状腺功能减退症成年患者常规使用甲状腺激素治疗。
