本文对27例过敏性紫癜肾炎儿科病例在急性期作血清CH_(50)、C_3、IgA、IgG、IgM、CIC、LTC和EAC测定,结果CH_(50)、C_3低于正常值分别各占14.8％和7.4％提示本症少数患者有低补体血症,可能补体介于肾小球的损伤。CIC增高者4/22例(18.2％)巳知免疫复合物与肾脏损害有密切关系,本组81.2％CIC是在正常范围,可能在本病急性期CIC大多沉着于肾小球基底膜上以至使血循环中的免疫复合物很少,LTC和EAC低于正常值分别占76％、72％提示可能有细胞免疫功能低下。IgM、IgG、大多数正常,而IgA增高5/27例其中有消化道症状4例,无消化道症状1例,有报道IgA的增高与消化道的关系,但本组尚难得到证实,看来有必要对IgA的质进一步研究。
Serum levels of CH_ (50), C_3, IgA, IgG, IgM, CIC, LTC and EAC were measured in 27 cases of allergic purpura nephritis. Results CH_ (50) and C_3 were 14.8 % And 7.4% suggest that a small number of patients with hypo-dyslipidemia may complement the glomerular damage. CIC increased 4/22 cases (18.2%) known immune complex and kidney damage are closely related to this group of 81.2% CIC is in the normal range, probably in the acute stage of CIC most of the deposition in the glomerular basement membrane and even The immune complex in the circulation is low, with LTC and EAC accounting for 76% of normal, respectively, and 72% suggesting possible cellular immune dysfunction. IgM, IgG, most of the normal, and IgA increased 5/27 cases, including gastrointestinal symptoms in 4 cases, 1 case of gastrointestinal symptoms, there is reported a relationship between IgA and gastrointestinal increased, but this group is hard to be confirmed, look It is necessary to further investigate the quality of IgA.
