Immune status of children with obstructive sleep apnea/hypopnea syndrome
Abstract
Objective: We aimed to evaluate the immune status of children with obstructive sleep apnea/hypopnea syndrome (OSAHS).
Methods: Fifty children with OSAHS having the symptoms of “snoring, mouth breathing and suffocating during sleepâ€, who were admitted in our hospital from May 2014 to May 2016, were randomly selected. Another 52 healthy, age- and gender-matched children were enrolled as control subjects after taking informed consent. After admission, the peripheral venous blood was collected. T cell subsets and cytokines were analyzed by flow cytometry. Immunoglobulin and complement levels were detected by immunoassay analyzer.
Results: The percentage of CD8+ T lymphocytes in children with OSAHS was (26.47 ± 1.52)% which was significantly higher than that of control group ((21.94 ± 1.92)%) (P<0.05). OSAHS group had a significantly lower CD4+/CD8+ ratio (1.24 ± 0.12) than that of control group (1.45 ± 0.11) (P<0.05). The two groups had similar percentages of CD3+ and CD4+ T lymphocytes (P>0.05). OSAHS group had significantly higher serum levels of IL-4, IL-6, IL-10 and IFN-γ than those of control group (P<0.05), but their IL-2 and TNF-α levels were similar (P>0.05). The serum IgA and C3 levels of OSAHS group significantly exceeded those of control group (P<0.05), but their IgG, IgM and C4 levels were similar (P>0.05).
Conclusion: Children with OSAHS had increased percentage of CD8+ T lymphocytes and decreased CD4+/CD8+ ratio, suggesting this group had poor immune function. Increase in humoral immune-related indices IL-4, IL-6, IL-10 and IFN-γ indicated the occurrence of oxidative stress and systemic inflammatory status.
