    • Immune thrombocytopenic purpura is treated by removal of IgG and circulating immune complexes from the patient's blood. Removal is accomplished by exposing the blood or blood plasma to an immunoadsorbent capable of removing IgG and its complexes. The immunoadsorbent comprises a suitable solid phase coupled to a receptor capable of binding IgG and its complexes, such as protein A. The IgG and its complexes are then removed by the extracorporeal exposure of the patient's blood to the immunoadsorbent, either in a continuous or discontinuous process. In the continuous process, the blood is removed in a steady flow from the patient, separated into its plasma and cellular components, the plasma treated, and the combined cellular components and treated plasma reinfused to the patient. In the discontinuous method, a small volume of blood is removed from the patient, the entire volume separated into plasma and cellular components, the plasma treated, and the entire volume of treated plasma returned to the patient, usually after the cellular components have been returned.
    • 免疫血小板减少性紫癜通过从患者血液中除去IgG和循环免疫复合物来治疗。 通过将血液或血浆暴露于能够除去IgG及其复合物的免疫吸附剂来实现去除。 免疫吸附剂包含与能够结合IgG及其复合物(例如蛋白A)的受体偶联的合适的固相。然后通过体外暴露患者的血液免疫IgG或其复合物,以免疫吸附剂将其连续或不连续 处理。 在连续过程中,以来自患者的稳定流动除去血液,分离成其等离子体和细胞组分,将血浆处理,并将组合的细胞组分和治疗的血浆重新灌注给患者。 在不连续的方法中,从患者体内除去少量的血液,整个体积分离成等离子体和细胞组分,血浆处理,经处理的血浆的总体积返回到病人,通常在细胞组分被返回后 。

    • Patients suffering from HIV-1 infection, including both those who have and those who have not developed acquired immunodeficiency syndrome, are treated by extracorporeal removal of IgG and immune complexes. An immunoadsorbent material for removing IgG and IgG-complexes from biological fluids is prepared by covalently binding protein A to a solid-phase silica matrix. It has been found that particularly stable, high-capacity immunoadsorbents are obtained by derivatizing the silica with amino and/or carboxyl groups, and reacting the protein A with a carbodiimide at a pH in a range from 3.5 to 4.5. Binding through free hydroxyl groups may be achieved with cyanogen halides at a pH in the range from 11.0 to 11.5. After acid washing (pH 2.0-2.5) to remove non-covalently bound protein A, the immunoadsorbent may be employed in a column for therapeutic treatment of various cancers and autoimmune disorders where IgG-complexes are implicated as suppressing factors in inhibiting a normal immune response.
    • 患有HIV-1感染的患者,包括那些患有和未发展成熟的免疫缺陷综合征的患者,通过体外去除IgG和免疫复合物进行治疗。 通过将蛋白A与固相二氧化硅基质共价结合来制备用于从生物流体中除去IgG和IgG-复合物的免疫吸附材料。 已经发现,特别稳定的高容量免疫吸附剂通过用氨基和/或羧基衍生二氧化硅获得,并且使蛋白A与碳二亚胺在3.5至4.5的pH范围内反应。 通过游离羟基的结合可以在pH为11.0至11.5范围内的氰卤化物达到。 在酸洗(pH2.0-2.5)以除去非共价结合的蛋白A后,免疫吸附剂可用于治疗各种癌症和自身免疫疾病的柱,其中IgG-复合物被认为是抑制正常免疫应答的抑制因子 。
