JCEM:血液中胰多肽的浓度能够预测内脏及肝脏的脂肪含量

一项来自英国的研究表明血液中的胰多肽浓度能够预测内脏和肝脏的脂肪含量,能够作为一种新型的指标,对于心血管疾病的风险分级以及脂肪异位沉积患者的而治疗来说都具有潜在价值。
预测内脏和肝脏脂肪含量的可靠生物指标迄今尚未被明确,这两种脂肪含量均是心血管疾病的危险因素。迷走神经兴奋被认为能够影响局部脂肪的分布,胰多肽是在迷走神经的调控下由胰腺分泌的。我们研究胰多肽在预测内脏和肝脏脂肪中的作用。

研究纳入了104名超重和肥胖患者(46名男性和58名女性),并测量他们空腹血浆中的胰多肽浓度。同样地,通过全身的磁共振成像(MRI)对他们的总脂肪和局部脂肪含量进行了了测量,包括总内脏脂肪组织(VAT))及总皮下脂肪组织(TSAT)。肝细胞内的脂肪含量(IHCL)通过质子磁共振波谱分析来确定。

血浆中胰多肽的浓度与内脏脂肪组织(VAT))(r=0.57, p<0.001)及肝细胞内的脂肪含量(IHCL)((r=0.51, p <0.001))成正相关,但与总的皮下脂肪组织(TSAT) (r=0.02, p=0.88)无关。在对患者的年龄和性别进行校正后,空腹血浆中的胰多肽浓度能够独立预测VAT。在对患者的年龄、性别、BMI、WHR、HOMA2-IR及血浆中甘油三酯、总胆固醇及丙氨酸转氨酶进行校正后,空腹血浆中的胰多肽浓度能够独立预测IHCL。空腹血浆胰多肽浓度与血浆中丙氨酸转氨酶、总胆固醇、甘油三酯、低密度脂蛋白和高密度脂蛋白及血压有关(p<0.05)。这种关联式有IHCL和/或VAT介导的。空腹血浆的胰多肽和HOMA2-IR分别与肝脏的脂肪变相关(p<0.01)。

胰多肽是一种新型的预测内脏和肝脏脂肪含量的指标,因此对于心血管疾病的风险分级以及脂肪异位沉积患者的而治疗来说都是一个具有潜在价值的生物指标。
