红细胞免疫黏附功能在系膜增生性肾小球肾炎发病机制中的作用

Action of Erythrocytes Immuno - Adhering in Pathogenesis of Children with Mesangio - Proliferative Glomeru-lonephritis

目的从红细胞免疫角度探讨系膜增生性肾小球肾炎(MsPGN)患儿的免疫发病机制。方法检测31例非IgA肾病,24例IgA肾病(IgAN)的红细胞和白细胞免疫黏附功能,并进行比较研究。结果1.作为检测红细胞免疫黏附功能的红细胞C3b受体花环率(RCR)、肿瘤红细胞花环率(TRR)均较对照组明显降低,红细胞免疫复合物花环率(RICR)差异不显著;2.作为检测白细胞免疫黏附功能的肿瘤粒细胞花环率(TNR)、肿瘤淋巴细胞花环率(TLR)均较对照组降低;3红细胞和白细胞免疫黏附功能的下降程度呈显著正相关。结论红细胞和白细胞免疫黏附功能紊乱可能是MsPGN的发病机制之一,提高红细胞和白细胞免疫黏附功能,可能为临床治疗MsPGN提供新思路。RCR、RICR、TRR、TNR、TLR均可作为判断病情、疗效、预后的指标应用于临床。

Objective To determine the role of erythrocytes immunoadhering in the pathogenesis of the patients with mesangiopro-liferative glomerulonephntis (MsPGN). Methods The immunoadhering functions of erythroeytes and leukoeytcs were measured in 31 patients with no- IgAN,24 patients with IgAN and 30 normal children by rosette tests:RCR,RICR,TRR,TNR and TLR. Results 1. The immunoadhering functions of erythroeytes (RCR and TRR) of the patients with no- IgAN and IgAN were obviously decreased compared to those of control group,but RICR showed no significant difference;2. The immunoadhering functions of leukocytes (TNR and TLR ) of the patients with no- IgAN and IgAN were obviously decreased compared to those of control group;3 The degree of the decreased immunoadhering functions of erythroeytes was correlated respectively with that of the immunoadhering functions of leukoeytes. Conclusions The decrease of the function of erythroeyte and leukocyte immunoadhering plays an important role in the pathogenesis in patients with MsPGN. These rosette tests may be used in clinic.
