Patients with primary immunodeficiency (PIDs) depend on the presence of a variety of antibody specificities in intravenous immunoglobulin (IVIG). Using the tick-borne encephalitis virus (TBEV), geographic variability in IVIG antibody content was shown. Care should therefore be exercised when treating PIDs in a given geography, as only locally sourced plasma contains the antibody specificities against the circulating pathogens in the given locality.
原发性免疫缺陷(PID)患者依赖静脉注射免疫球蛋白(IVIG)中多种抗体特异性的存在。利用蜱传脑炎病毒(TBEV),已显示出IVIG抗体含量存在地理差异。因此,在特定地区治疗PID时应谨慎,因为只有当地来源的血浆才含有针对该地区循环病原体的抗体特异性。
