Diabetes:纵向结果支持糖化血红蛋白6.5的诊断阈值

2012-08-21 高晓方 医学论坛网

  美日学者的一项研究表明,纵向研究结果支持糖化血红蛋白(HbA1c)阈值≥6.5%诊断糖尿病的有效性。论文于2012年8月13日在线发表于《糖尿病》(Diabetes)杂志。    HbA1c阈值基于横断面研究证据而制定,尚无纵向研究支持其有效性。此项研究共纳入19897例日本成人受试者,并对其进行了为期3年的随访。利用Logistic回归模型和限制性立方样条模型评估基线HbA1c水平与视网膜

  美日学者的一项研究表明,纵向研究结果支持糖化血红蛋白(HbA1c)阈值≥6.5%诊断糖尿病的有效性。论文于2012年8月13日在线发表于《糖尿病》(Diabetes)杂志。

   HbA1c阈值基于横断面研究证据而制定,尚无纵向研究支持其有效性。此项研究共纳入19897例日本成人受试者,并对其进行了为期3年的随访。利用Logistic回归模型和限制性立方样条模型评估基线HbA1c水平与视网膜病变患病率与3年发病率的相关性。

  结果显示,限制性立方样条模型提示偶发性视网膜病变风险的可能阈值为HbA1c 6.0%~7.0%。Logistic回归分析显示,与HbA1c 5.0%~5.4%相比,HbA1c 6.5%~6.9%的受试者罹患视网膜病变的风险显著升高。HbA1c 5.5%~6.4%的受试者无风险升高证据。

2型糖尿病致老年骨形成降低

  近日,苏州大学附属第二医院内分泌代谢病科的庞东岳、史蕾、张弘弘等共同发表论文,旨在通过测定男性2型糖尿病(T2DM)患者及健康人群的骨代谢及相关指标,探讨T2DM对骨代谢的影响及其相关因素。研究指出,与正常对照组相比,T2DM患者的骨形成降低,而骨吸收增加。随着病程增加,T2DM患者骨质形成速率进一步减慢,而骨吸收无明显增加。血糖控制不佳可致骨形成减缓、骨质吸收增加而影响骨代谢。该论文发表于2
