糖尿病肾病患者血清AT1受体和β1受体自身抗体与血清半胱氨酸蛋白酶抑素C的关系
Relationship of positive rate of β1-adrenergic and AT1 receptor autoantibodies with serum cystatin C concentration in the patients with diabetic nephropathy
观察371例糖尿病肾病患者、107例2型糖尿病患者和47名对照者血清β1肾上腺素能(β1)和血管紧张素Ⅱ1型( AT1)受体自身抗体阳性率与血清半胱氨酸蛋白酶抑素C(Cys-C)的关系.结果显示糖尿病肾病患者β1和AT1受体自身抗体阳性率明显高于2型糖尿病患者,糖尿病肾病患者中Cys-C异常者β1和AT1受体抗体阳性率明显高于Cys-C正常者.提示Cys-C异常与肾损害有关,更进一步表明糖尿病肾病与AT1和β1受体自身抗体有关.
更多To observe the relationship between positive rate of β1-adrenergic and AT1 receptors autoantibodies with serum concentration of cystatin C in 371 patients with diabetic nephropathy patients,107 patients with type 2 diabetes,and 47 subjects as healthy control.In patients with diabetic nephropathy,the positive rates of the β1 and AT1 receptors autoantibodies were significantly higher than those in patients with type 2 diabetes and normal controls.The titers of β1 and AT1 receptors autoantibodies in diabetic nephropathy patients with abnormal cystatin C were significantly higher than those with normal cystatin C concentration.These findings suggested that β1 and AT1 receptors autoantibodie may play important roles in the pathogenesis of diabetic nephropathy.
