生命早期适应性细胞因子产生能差异性预测5岁内总IgE水平和哮喘发生
2011/08/31
摘要
背景:虽然研究已经证实,过敏性疾病与Th2细胞增加有关,但IgE水平和哮喘与生命早期细胞因子产生之间的关系是否一致尚不清楚。
目的:该项非选择性出生队列研究评价了1岁内适应性免疫细胞因子产生水平与5岁内哮喘和总IgE水平之间的关系。
方法:检测出生时、3个月时和12个月时脐血单核细胞和PBMC在有丝分裂原(刀豆素A/佛波醇-12 -肉豆蔻-13-醋酸)刺激后产生的IL-4、IL-5、IL-13和IFN-γ水平。在第1、2、3和5岁时,评价总血清IgE水平和医生诊断的活动性哮喘。经Th1和Th2细胞因子产量校正后的纵向模型被用于检测哮喘转归间的相关性。
结果:细胞因子与总IgE水平和哮喘之间的关系存在显著不同。5岁内,经IFN-γ水平校正后,总IgE水平与12个月时的IL-4 (P <0.001)、IL-5(P <0.001)和IL-13 (P =0.02)水平成正相关,经IL-4水平校正后,与12个月IFN-γ水平成负相关(P =0.01)。5岁内,经IFN-γ水平校正后,活动性哮喘与3个月时的IL-13水平成正相关(优势比:2.6; P <0.001),经IL-13校正后,与3个月时的IFN-γ水平成负相关(优势比:0.5; P =0.001)。这些相关性在非特应性哮喘患者中更为显著。
结论:5岁内,总IgE水平和哮喘的发生与生命早期适应性细胞因子产生相关,但该相关性存在差异,而且各细胞因子的重要性尚不清楚。

Abstract
BACKGROUND: Although it has been postulated that allergic disease is associated with a predominance of T(H)2 cells, whether IgE levels and asthma might differ in their relation to early-life cytokine production is not known.
OBJECTIVE: We sought to assess the relationship between first-year adaptive immune cytokine production with asthma and total IgE levels through age 5 years in a nonselected birth cohort.
METHODS: Mitogen (concanavalin A/phorbol 12-myristate 13-acetate)-stimulated IL-4, IL-5, IL-13, and IFN-γ levels were measured in supernatants from cord blood mononuclear cells and PBMCs at birth, 3 months, and 12 months. Total serum IgE levels and physician-diagnosed active asthma were assessed at 1, 2, 3, and 5 years. Longitudinal models that adjust for both T(H)1 and T(H)2 cytokine production were used to determine relations of outcomes.
RESULTS: Relations of cytokines to total IgE levels and asthma were strikingly different. Total IgE levels through age 5 years were positively associated with 12-month IL-4 (P < .001), IL-5 (P < .001), and IL-13 (P = .02) levels when adjusted for IFN-γ levels and inversely associated with 12-month IFN-γ levels after IL-4 adjustment (P = .01). Active asthma through age 5 years was positively associated with 3-month IL-13 levels adjusted for IFN-γ (odds ratio, 2.6; P < .001) and inversely associated with 3-month IFN-γ levels adjusted for IL-13 (odds ratio, 0.5; P = .001). These relations were strongest for nonatopic asthma.
CONCLUSION: Total IgE levels and active asthma through age 5 years are associated with adaptive cytokine production in early life, although relations vary temporally and with regard to the relative importance of individual cytokines.
