Effect of pidotimod combined with azithromycin on children with mycoplasma pneumonia and the expression levels of IL-10 and G-CSF in serum

This study explored the effect of pidotimod combined with azithromycin on children with mycoplasma pneumonia and the expression of interleukin-10 (IL-10) and granulocyte colony-stimulating factor (G-CSF) in serum. The clinical data of 149 children with mycoplasma pneumonia from May 2014 to May 2018 in Zhangqiu District Maternal and Child Health Care Hospital were collected. Among them, 70 children treated with azithromycin sequential therapy were the control group, and 79 children treated with the combination of pidotimod and azithromycin were the observation group. Double antibody sandwich enzyme-linked immunosorbent assay (ELISA) was used to determine the expression levels of IL-10 and G-CSF in serum before and after treatment. Pearson's correlation coefficient was used to analyze the correlation between IL-10 and G-CSF in serum. The total effective rate in the observation group (94.94%) was significantly higher than that in the control group (81.43%) (P<0.05). There was no significant difference in the expression levels of IL-10 and G-CSF between the two groups before treatment (P>0.05). The expression levels of IL-10 and G-CSF in the two groups after treatment were significantly lower than those before treatment (P<0.05). After treatment, the expression levels of IL-10 and G-CSF in serum in the observation group were significantly lower than those in the control group. There was a significant positive correlation between the expression levels of IL-10 and G-CSF before and after treatment in the observation group (P<0.05), and a significant positive correlation between the expression levels of IL-10 and G-CSF before and after treatment in the control group (P<0.05). Compared with sequential treatment with azithromycin alone, pidotimod combined with azithromycin significantly reduced the expression levels of IL-10 and G-CSF in serum of children with mycoplasma pneumonia, improved the curative effect and reduced the occurrence of adverse reactions, which has high application value in clinic.
