Abstract:
Objective To explore the impact of levels of serum IL-17,Leukotriene B4 and IgE on pathogenesis of childhood asthma.Methods Totally 60 children with asthma acute exacerbation ( 29 children with mild asthma,31 children with moderate-severe asthma) were selected as study group,24 healthy children were selected as control group.Serum IL-17 and LTB4 were measured with euryzemLinked immunosorbent assay,serum IgE was determined with enzyme-linked fluoroimmuneassay by pharmacia CAP Sytem,PMN was determined with automatic blood analyser,pulmonary function was measured in the study group.Results ( 1 ) The level of serum IL-17 ( 1.15 ± 0.10 μg/L,2.80 ± 2.30 μg/L,0.83 ± 0.10 μg/L),LTB4 (2.22 ± 1.01 μg/L,8.79 ± 9.36 μg/L,1.94 ± 1.13 μg/L) and IgE( 123.70 ±86.94 μg/L,322.27 ±332.28 μg/L,24.27 ±7.64 μg/L) were significantly different among mild asthma group,moderate-severe asthma group and control group( P ＜ 0.001 ).( 2 )The N％ of mild asthma group,moderate-severe asthma group and study group were( 55.06 ± 1 1.15 ) ％,( 64.44± 11.87)％,(47.96 ± 13.52)％,L％ were(42.20 ± 11.04)％,(33.93 ± 10.02)％,(49.65 ± 13.02)％,and there were significant differences in N％ and L％ between study group and control group( P ＜ 0.05 ).( 3 ) There were significant positive correlations between the serum IL-17 levels and IgE,LTB4 and IgE,IL-17 and LTB4 in asthmatic children( P ＜0.05).(4) There were significant negative correlcations between the level of serum IL-17,LTB4 and FEVI,PEF( P ＜0.001 ).There were significant positive correlations between serum IL-17,LTB4 and N％ (P ＜0.001 ).(5)There were not correlations between the level of serum IgE and FEV1,PEF and N％in asthmatic children( P ＞0.05 ).Conclusion The levels of serum IL-17,LTB4 and IgE participated in pathogenesis on asthmatic children patients.
