Abstract:
Objective To explore the interleukin (IL)-6,IL-10 and T cell subsets levels in bronchoalveolar lavage fluid(BALF) of children with refractory mycoplasma pneumonia.Methods A total of 53 children with refractory mycoplasma pneumonia were selected as the observation group,30 children with bronchial foreign body in our hospital were chosen as controls during the same period.ABC-double antibody sandwich ELISA method was used to detect IL-6,IL-10 levels and the CD3 +,CD4 + and CD8 + T levels were measured by means of flow cytometry in BALF.Results The IL-6 and IL-10 levels in BALF of children in the observation group were (63.25 ± 18.61) ng/ml,(31.83 ± 8.33) ng/ml respectively,and they were significantly higher than those of the controls[(30.51 ± 1.34) ng/ml,(11.01 ± 2.91) ng/ml] (P ＜ 0.05,respectively).The percentage of CD3 +,CD4 +,CD8 + T cells and the ratio of CD4 +/CD8 + T cells in BALF of the observation group were (48.47 ± 2.88)％,(21.16 ± 6.29)％,(23.04 ± 4.63)％,0.94 ± 0.33,respectively,and they were significantly lower than those of the controls [(64.24 ± 3.06) ％,(34.34 ± 7.59) ％,(26.71 ±5.29)％,1.56-±0.67] (P＜0.05,respectively).Conclusion The IL-6,IL-10 levels in BALF of children with refractory mycoplasma pneumonia significantly increased,suggesting that cell-mediated immunity play an important role in the pathogenesis of refractory mycoplasma pneumonia.
