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 sleep", 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-gamma than those of control group [P<0.05], but their IL-2 and TNF-alpha 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-gamma indicated the occurrence of oxidative stress and systemic inflammatory status
