Article Serum Immunoglobulins and Immunoglobulin G Subclasses With Recurrent Wheezing(The Indian Journal of Pediatrics, 2000) Öner, A.F.; Çaksen, H.; Çelik, A.; Cesur, Y.; Üner, A.; Arslan, S.In this study serum immunoglobulins (Ig) and IgG subclasses were measured in 42 patients (ranging 9 month-6 year) with recurrent wheezing and in 37 healthy children determined the relationship between serum Igs and recurrent wheezing. Patients were divided into two groups according to the age [9 month-2 year (n: 15), and 2-6 year (n: 27)]. In the patients placed in 9-24 month age group, serum IgG4 level was found to be lower than controls (p<0.05). But there was not a significant difference in mean serum concentrations of total IgG, IgA, IgM, IgE, IgG1, IgG2 and IgG3 subclasses between the groups (P>0.05). In the 25 month-6 year age group the mean IgE level was increased compared to the control while IgG3 and IgG4 levels were decreased (p<0.05). On the other hand, in the 9-24 month age group there was no significant difference between the patients and controls for IgG subclasses deficiency (P>0.05). However, significant difference in IgG subclasses deficiency was present between the patients and controls in the 25 month-6 year group (P<0.001). In conclusion, our findings suggest that wheezing in childhood may be associated with low IgG3 and/or IgG4, and in older children high IgE level may be a part of pathogenetic mechanism in patients with recurrent wheezing.
