Pi phenotypes of alpha-1-protease inhibitor were determined by isoelectric focusing and print immunofixation in 96 English children suffering from juvenile chronic polyarthritis. A significantly increased frequency of the MZ phenotype (10.41%) was found in comparison with a geographically matched control population (1.6%). The results of this study suggest that the possession of a Z-deficient allele of alpha-1-protease inhibitor could be a predisposing, aggravating, or perpetuating factor in the articular damage occurring in juvenile chronic polyarthritis.
采用等电聚焦和印迹免疫固定法,对96名患幼年型慢性关节炎的英国儿童测定了α1-蛋白酶抑制剂的Pi表型。与地理位置匹配的对照人群(1.6%)相比,发现MZ表型的频率显著增加(10.41%)。本研究结果提示,α1-蛋白酶抑制剂的Z缺陷等位基因的存在可能是幼年型慢性关节炎关节损伤的一个易感、加重或持续因素。
