Children with croup appearing in the presence of acute viral respiratory diseases (AVRD) show an increase in the IgM content in their blood sera during the first days of the disease followed by a decrease, and an increase in the IgG and IgE levels during the convalescence period. No essential shifts in the content of IgA have been observed. The total content of the immunoglobulins in children with croup, was lowered as compared to that in AVPD patients having no croup which is, probably, of a certain pathogenic importance. The increased content of IgE revealed in the blood sera of children with croup indicates the presence of an allergic component in this disease.
患有哮吼且伴有急性病毒性呼吸道疾病（AVRD）的儿童，在疾病初期血清中IgM含量升高，随后下降，恢复期IgG和IgE水平升高。未观察到IgA含量有显著变化。与无哮吼的AVPD患者相比，哮吼患儿的免疫球蛋白总含量降低，这可能具有一定的致病重要性。哮吼患儿血清中IgE含量增加表明该疾病存在过敏成分。
