Abstract

Leucocyte-mediated phagocytosis and antibody-dependent cellular cytotoxicity (ADCC) were tested in 48 children with type-1 diabetes and in 22 healthy children. Both phagocytosis and ADCC for opsonized 51Cr-erythrocytes significantly decreased in the diabetics. Phagocytosis decreased in well and in poorly balanced diabetics, but the latter, having type-1 diabetes for less than 5 years, exhibited a lower phagocytic capacity than the patients with a longer duration of disease. The decrease of ADCC in poorly balanced patients was greater than in the well balanced ones as compared to the controls. The duration of diabetes was without influence on their leucocytes' ADCC.

1型糖尿病患者吞噬功能和抗体依赖性细胞毒性(ADCC)降低。
在48例1型糖尿病儿童和22例健康儿童中检测了白细胞介导的吞噬和抗体依赖性细胞毒性(ADCC)。糖尿病患者51cr -红细胞的吞噬和ADCC均显著降低。在平衡良好和平衡不良的糖尿病患者中,吞噬能力下降,但后者,患有1型糖尿病少于5年,表现出较低的吞噬能力,比病程较长的患者。与对照组相比,平衡不良的患者ADCC的下降幅度大于平衡良好的患者。糖尿病病程对白细胞ADCC无影响。
