dc.description.abstractBackground: IgG subclass deficiency is a laboratory diagnosis and becomes important with recurrent infections. This study aimed to examine the demographic, clinical, and laboratory results of pediatric cases with IgG subclass deficiency and to improve the understanding of the clinical significance of IgG subclass deficiency. Methods: In this study, the clinical and laboratory features of 111 pediatric patients, with at least one whose serum IgG subclasses was measured as lower than 2 standard deviation of healthy aged-matched control values, were evaluated. The clinical and laboratory features of the cases with isolated IgG subclass deficiency (Group 1) and those with low serum levels of any of IgG, IgA, and IgM in addition to the IgG subclass deficiency (Group 2) were compared. Results: A total of 55 (49.54%) and 56 (50.45 %) patients were included in Groups 1 and 2, respectively. Among our studied cases, 20 (18. 1%) had a history of hospitalization in the neonatal period, 61 (54.95 %) had at least one hospitalization due to infection, and 55 (49.54%) had a history of recurrent infection. The frequencies of these three conditions were statistically significantly higher in Group 2 (p < 0.05). The frequencies of infections in the last year in Groups 1 and 2 were 4.4 +/- 1.2 and 5.4 +/- 1.9, respectively (p < 0.05). As a result of recurrent infections, 43.24% (n = 48) of our patients received antibiotic prophylaxis, and 21.62% (n = 24) had immunoglobulin replacement therapy. Furthermore, the numbers of pa-tients who needed these treatments were higher in Group 2 (p < 0.05).Conclusion: In cases with IgG subclass deficiencies, concomitant main-group immunoglobulin deficiencies may increase the number and severity of infections, leading to hospitalizations, antibiotic prophylaxis, and immunoglobulin therapy. More attention should be paid to cases of immunoglobulin main-group deficiencies in the follow-up of these cases.Copyright (c) 2022, Taiwan Pediatric Association. Published by Elsevier Taiwan LLC.
