JCEM:爱迪生氏病患者应注意心血管疾病风险

2017-09-30 MedSci MedSci原创

爱迪生氏病(Addison's disease)又名阿狄森氏病、Addison病,即原发性肾上腺功能不足 (primary adrenal insufficiency),是肾上腺无法分泌足够的皮质醇所引发的疾病。由于血中低浓度的皮质醇引发负回馈,使得促皮质醇激素(ACTH)分泌增加而呈现典型上升情形。

背景:爱迪生氏病(Addison's disease)又名阿狄森氏病、Addison病,即原发性肾上腺功能不足 (primary adrenal insufficiency),是肾上腺无法分泌足够的皮质醇所引发的疾病。由于血中低浓度的皮质醇引发负回馈,使得促皮质醇激素(ACTH)分泌增加而呈现典型上升情形。

目前爱迪生氏病(AD)患者的心血管死亡率在增加。

目的:本研究旨在研究AD患者的内脏脂肪及常规和探索性心血管危险因素。

设计:这是一个横断面、单中心、病例对照研究。研究纳入了76名(其中51名为女性)AD患者和76名性别、年龄、体重指数(BMI)和吸烟习惯相匹配的健康对照者。主要观察指标包括:主要结果变量为腹部脂肪组织(VAT)。次要结果变量是代谢综合征的患病率和心血管疾病的92个生物标志物。

结果:患者组和对照组的平均年龄(± SD)为53±14岁,平均体重指数为25±4kg/m2,平均AD病程为17±12年。每日氢化可的松剂量的中位数(范围)为30毫克(10-50毫克)。与对照组相比,患者组的24小时尿游离皮质醇排泄的中位数(四分位距)有所增加(患者组:359[193-601]nmol/L vs 对照组:175[140-244]nmol/L;P<0.001)。VAT在两组间没有不同(76[39-132]cm2 vs 71[43-135]cm2;P = 0.7)。

校正多个测试后,92个研究的生物标记物中有17个在患者和对照组之间表现出了显著差异。炎症、促炎性和促动脉粥样硬化的风险生物标志物水平在患者组增加(差异倍数:FC>1),而舒张血管的保护标志水平出现了下降(FC<1)。

患者组有26例(34%)vs 对照组有12例(16%)符合代谢综合征的诊断标准(P=0.01)。

结论:尽管皮质醇暴露较高,但AD患者的VAT并没有增加。然而,AD患者的代谢综合征患病率增加,且心血管疾病的一些生物标记物受到不利影响。
