ABSTRACT
SUMMARY OBJECTIVE To investigate the relations of T lymphocytes, cytokines, immunoglobulin E, and nitric oxide with otitis media with effusion (OME) in children and their clinical significances. METHODS Fifty children with OME treated in our hospital were enrolled in the study (observation group). Fifty healthy children were selected as control. The percentages of CD4+ and CD8+ T lymphocyte and CD4+/CD8+ ratio in peripheral blood, and the levels of cytokine (IL)-2, IL-4, IL-6, immunoglobulin E (IgE) and nitric oxide (NO) in peripheral blood and middle ear effusion (MEE) in both groups were detected. The correlations of these indexes with OME were analyzed. RESULTS The percentage of peripheral blood CD4+ and CD8+ levels, CD4+/CD8 ratio, IgE, and NO levels in the observation group were significantly higher than those in the control group (P < 0.01). In the observation group, the IL-2 and IL-6 levels, and IgE and NO levels in the MEE were significantly higher than those in peripheral blood (P < 0.01). In addition, in the observation group, the MEE IL-2 and IL-6 levels were positively correlated with peripheral blood CD4+/CD8+ ratio, respectively r = 0.366, P = 0.009; r = 0.334, P = 0.018. CONCLUSIONS The levels of peripheral blood CD4+ and CD8+ lymphocytes and MEE IL-2, IL-6, IgE, and NO levels are increased in children with OME. These indexes have provided significant clues for the diagnosis of OME in children.
RESUMO
RESUMO OBJETIVO Investigar as relações entre linfócitos T, citocinas, imunoglobulina E e óxido nítrico e a otite média com efusão (OME) em crianças e sua significância clínica. MÉTODOS Cinquenta crianças com OME tratadas em nosso hospital foram incluídas no estudo (grupo de observação). Selecionamos também 50 crianças saudáveis como controle. As porcentagens de linfócitos T CD4 + e CD8 + e a razão CD4+/CD8+ no sangue periférico, além dos níveis das citocinas IL-2, IL-4, IL-6, imunoglobulina E (IgE) e óxido nítrico (NO) no sangue periférico e de efusão no ouvido médio (MEE) de ambos os grupos foram medidos. A correlação desses índices com a OME foi analisada. RESULTADOS A porcentagem dos níveis de CD4+ e CD8 +, da razão CD4+/CD8+, de IgE e NO no sangue periférico do grupo de observação foram significativamente maiores do que no grupo controle (P < 0,01). No grupo de observação, os níveis de IL-2 e IL-6, IgE e NO em MEE foram significativamente maiores do que no sangue periférico (P < 0,01). Além disso, no grupo de observação, foi encontrada uma correlação positiva entre os níveis de IL-2 e IL-6 em MEE e a razão de CD4+/CD8+no sangue periférico, respectivamente, r = 0,366, P = 0,009; r = 0,334, P = 0,018. CONCLUSÃO Os níveis de linfócitos CD4 + e CD8 + no sangue periférico e IL-2, IL-6, IgE e NO em MEE são mais altos em crianças com OME. Esses índices forneceram evidências valiosas para o diagnóstico de OME em crianças.
