  • Influence of Immunoglobulin on Cellular Immune Function of Postoperative Infants with Cyanotic Congenital Heart Disease

    ObjectiveTo investigate the influence of immunoglobulin (Ig)on celluar immune function of postoperative infants with cyanotic congenital heart disease (CCHD). MethodsForty infants who underwent surgical repair of CCHD in Department of Cardiac Surgery, Children's Hospital of Hebei Province from March to December 2012 were enrolled in this study. All the patients were randomly divided into 2 groups. Patients in Ig group received intravenous Ig treatment at the dosage of 1g/ (kg·day)for 2 days postoperatively in addition to routine therapy. Patients in the control group only received routine therapy without Ig treatment. Five ml venous blood samples of all the patients were taken preoperatively, 0.5 hour and 2 days postoperatively to examine serum levels of interferon gamma (IFN-γ)and interleukin-4 (IL-4)with double-antibody sandwich enzyme-linked immunosorbent assay (ELISA), which were compared between the 2 groups. ResultsThere was no statistical difference in serum levels of IL-4 or IFN-γ preoperatively and at 0.5 hour postoperatively between the 2 groups (P > 0.05). Serum levels of IL-4 and IFN-γ at 0.5 hour postoperatively were significantly higher than preoperative levels in the 2 groups respectively (P=0.000). Serum IL-4 level of Ig group 2 days postoperatively was not statistically different from preoperative level (P=0.362), while serum IL-4 level of the control group 2 days postoperatively was significantly higher than preoperative level (P=0.006). Two days after the operation, serum levels of IL-4 and IFN-γ of Ig group were significantly lower than those of the control group respectively (P=0.039 and 0.007 respectively). Compared with serum levels at 0.5 hour postoperatively in the control group, serum IL-4 level at 2 days postoperatively decreased by 20.08% (P=0.001), and serum IFN-γ increased by 17.80% (P=0.001). Compared with serum levels at 0.5 hour postoperatively in Ig group, serum IL-4 level at 2 days postoperatively decreased by 35.38% (P=0.000), and serum IFN-γ only increased by 7.60% (P=0.143). ConclusionCellular immune function disorder caused by the operation and cardiopulmonary bypass can be effectively improved by postoperative intravenous Ig administration, which may help to reduce postoperative complications.
