We aimed to study the correlation of adiponectin level with insulin resistance (IR), carotid intima-media thickness (cIMT), and various obesity indices especially visceral adipose tissue (VAT) thickness, and visceral adiposity index (VAI), in patients with NAFLD ( = 41), T2D ( = 22), NAFLD + T2D ( = 41), and healthy subjects ( = 20). Results showed the median level of adiponectin in patients with NAFLD (2.97 μg/mL) and ones with NAFLD + T2D (3.21 μg/mL) is significantly lower rather than in controls (4.39 μg/mL). Moreover, VAI is the only predictor for adiponectin concentration in the combination of patient groups and also in all participants independent of IR and other obesity indices. Adiponectin level had also a positive correlation with cIMT and IR in NAFLD patients. Interestingly, lower level of adiponectin was associated with the presence of T2D, NAFLD, and NAFLD + T2D independent of IR and obesity indices. Collectively, it seems that VAI reflecting visceral adipose tissue function is a possible predictor of adiponectin level.
我们旨在研究脂联素水平与胰岛素抵抗(IR)、颈动脉内膜中层厚度(cIMT)以及各种肥胖指数(尤其是内脏脂肪组织[VAT]厚度和内脏脂肪指数[VAI])在非酒精性脂肪性肝病(NAFLD)患者( = 41)、2 型糖尿病(T2D)患者( = 22)、NAFLD + T2D 患者( = 41)和健康受试者( = 20)中的相关性。结果显示,NAFLD 患者(2.97μg/mL)和 NAFLD + T2D 患者(3.21μg/mL)的脂联素中位数水平明显低于对照组(4.39μg/mL)。此外,VAI 是患者组和所有参与者中除 IR 和其他肥胖指数外,唯一预测脂联素浓度的因素。脂联素水平与 NAFLD 患者的 cIMT 和 IR 呈正相关。有趣的是,较低的脂联素水平与 T2D、NAFLD 和 NAFLD + T2D 的存在独立于 IR 和肥胖指数相关。总的来说,反映内脏脂肪组织功能的 VAI 似乎是脂联素水平的一个可能预测因素。
