[Show abstract][Hide abstract] ABSTRACT: Infections remain the leading cause of death in burn patients. Immune responses play an important role in patient's defense mechanism against infection and decreasing morbidity and mortality associated with burn. Our goal was to determine serum immunoglobulin levels in pediatric burn patients in order to understand role of humoral immune defense in these patients. During this analytic cross sectional study from January 2011 to February 2012, all patients with burn and younger than 6 years old that were referred to Shahid Motahari burn and reconstruction center were enrolled. Patients had no inhalation injury or sepsis. Immunoglobulin levels were measured once on 3–5 days after burn. The burn size in 12 patients (24%) was less than 30%, in 30 patients (60%) were between 30% and 50% and in the remained 8 patients (16%) were more than 50%. In 45 patients (90%) depth and severity of burn were 2nd degree (superficial and deep) and in the remaining 5 patients (10%), it was 3rd or 4th degree. In 28 (56%), 1 (2%), 3 (6%), 35 (70%), 48 (96%), 19 (38%) and 6 (12%) patients IgG, IgM, IgA, IgG1, IgG2, IgG3 and IgG4 were lower than normal values, respectively. No significant correlation was seen between burn size (TBSA) and value of immunoglobulin (P > 0.05). Although the drop in the serum concentration of immunoglobulins is irrespective to the burn size, more severe burn is associated with more decrease in the serum levels of IgA, IgM, IgG and its subclasses. However, further studies are needed to provide complementary data on this issue.
