Effect of pidotimod combined with Yanhuning on children with refractory Mycoplasma pneumonia clinical symptoms and immune function / 中国生化药物杂志

Objective To investigate the the curative effect of pidotimod combined with Yanhuning for children with refractory mycoplasma pneumonia(RMPP).Methods90 patients with RMPP from January 2013 to January 2015in shengzhou maternal and child health care hospital were divided into 3 groups, including Yanhuning group(A group), azithromycin combined with Yanhuning group(B group)and pidotimod combined with Yanhuning group(C group).And the total effective rate, the clinical symptoms, immune function parameters were analyzed.ResultsThe regulation of immune function in C group was more significant than that in A group and B group, the prognosis was better, and the repeated times and continuous time were decreased (P<0.05).ConclusionPidotimod combined with Yanhuning treatment of RMPP can regulate the immune function of children, improve clinical symptoms, it is worthy of popularization.

Effect and safety of gamma globulin combined with glucocorticoid pulse therapy on serum CRP in children with refractory mycoplasma pneumonia / 中国生化药物杂志

Objective To investigate the effect of gamma globulin combined with glucocorticoid pulse therapy in the treatment of children with refractory mycoplasma pneumonia in CRP and safety.Methods 46 cases of children with refractory mycoplasma pneumonia from February 2012 to February 2016 were selected and randomly divided into the control group and experimental group,23 cases in each group.On the basis of the regular treatment,the control group was given azithromycin,10mg/kg,qd,intravenous drip,on the basis of the control group treatment,the experimental group was treated with methylprednisolone 2mg/kg+human immunoglobulin 400mg/kg,qd,intravenous drip.The levels of serum C-reactive protein(CRP),white blood cell count(WBC),lymphocyte count(LC),therapeutic efficiency and safety were measured before and after treatment.Results After treatment,compared with the control group,the serum levels of CRP、WBC、LC were lower in the experimental group,the difference was statistically significant(P<0.05).The treatment efficiency of the experimental group(91.31％)was significantly higher than that of the control group(65.22％),the difference was statistically significant(P<0.05).There was no significant difference in the incidence of adverse reactions between the two groups.Conclusion The gamma globulin combined with glucocorticoid pulse therapy can significantly reduce the serum levels of CRP,WBC and LC in children with refractory mycoplasma pneumonia,improve clinical efficacy and the safety were good.

Levels of interleukin-6,interleukin-10 and T cell subsets in bronchoalveolar lavage fluid of children with refractory mycoplasma pneumonia / 中国小儿急救医学

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.
