An 11 year old girl with retarded growth, recurrent infections, bronchiectasis, and normal serum immunoglobulin concentrations had a combined deficit of the IgG2 subclass and IgG and IgM specific antibodies. Immunoglobulin replacement was followed by clinical improvement. The importance of determining both IgG subclasses and antibody activity in patients with recurrent infections and normal serum immunoglobulin values is emphasised.
一名11岁女孩生长发育迟缓、反复感染、患有支气管扩张症,血清免疫球蛋白浓度正常,但存在IgG2亚类以及IgG和IgM特异性抗体的联合缺陷。进行免疫球蛋白替代治疗后临床症状改善。强调了对于反复感染且血清免疫球蛋白值正常的患者,测定IgG亚类和抗体活性的重要性。
