摘要 目的 :探讨过敏性胃肠病患儿血清维生素D水平及其与嗜酸性粒细胞和Ig E之间的相关性。方法 :以25例健康儿童为对照,酶联免疫法测定41例过敏性胃肠病患儿血清25羟维生素D3[25(OH)D3]水平,用化学荧光法和免疫印迹法分别测定总Ig E和过敏原特异性Ig E(s Ig E)。结果:过敏性胃肠病患儿外周血25(OH)D3水平与对照组无差别(P>0.05),但维生素D不足[(25(OH)D3<75 nmol/L]的比率高(P<0.05)。虽然维生素D不足和维生素D水平正常[25(OH)D3≥75 nmol/L]的患儿外周血嗜酸性粒细胞计数在过敏食物回避前无显著差别(P>0.05),维生素D正常患儿嗜酸性粒细胞比率和绝对计数在过敏食物回避1周后显著下降(P<0.05),而维生素D不足患儿过敏食物回避后嗜酸性粒细胞比率和绝对计数与回避前比较,差异无统计学意义(P>0.05)。并且维生素D不足患儿血清总Ig E水平、总Ig E>180 U/L比率和s Ig E阳性率均高于维生素D正常组。结论:维生素D水平状态与过敏性胃肠病患儿嗜酸性粒细胞和Ig E升高有关。
