摘要
目的检测健康人及变应性鼻炎（AR）患者治疗前后外周血嗜酸粒细胞（eosinophils，EOS）-骨髓干细胞通路相关指标CD34^＋、白细胞介素5（IL-5）、EOS，探讨外周血-骨髓通路在变应性鼻炎发病机制中的作用以及糖皮质激素对此通路的影响。方法实验分2组：①试验组：常年性持续性变应性鼻炎患者44例，男24例，女20例，年龄7～68岁；给予糖皮质激素治疗4周；②健康对照组：健康体检者30例。分别检测试验组治疗前后和对照组外周血EOS计数，血清IL-5水平及CD34^＋细胞数，并分析各指标间的相关性。结果试验组治疗前血清IL-5含量、CD34^＋数分别为（88．25±33．47）ng／L、（9．24±2．15）个／10^5，显著高于治疗后[（44．34±16．32）ng／L、（6．31±1．83）个／10^5]及健康对照组[（31．24±8．43）ng／L、（3．47±1．32）个／10^5]。试验组治疗前后血清IL-5水平与其CD34^＋数呈显著正相关（r值分别为0．64、0．61，P值均〈0．01）。患者血清IL-5水平与其EOS数呈显著正相关（r=0．64，P〈0．01）。结论外周血EOS、IL-5及CD34^＋细胞参与AR发病过程，提示AR患者病变局部组织和骨髓造血之间有相关通路存在。通过检测外周血IL-5及CD34^＋可评价治疗效果。
Objective By means of the detection of the numbers of CD34 cells and eosinophils （EOS） , and the level of IL-5 in peripheral blood from normal controls and patients with allergic rhinitis pre- or post-treatment, the role of EOS-stem cells paths for treatment effect in allergic rhinitis （ AR ） was studied so as to find the convenient and quick indicators which could be used to evaluate the clinical therapeutic effect and adjust the methods of the hormone therapy. Methods There were 2 groups. （ 1 ） experimental group： 44 patients, including 24 males and 20 females with a age range of 7 to 68 years old, The patients received the treatment of fluticasone spurt for four weeks. （ 2 ） Control group ： 30 cases, from normal health examination. The EOS numbers, CD34^＋ cell numbers and the IL-5 level were examined in control group as well as before and after therapy in experimental group . Results The IL-5 level and CD34^＋ numbers before tbearpy in experimental group were （ 88. 25 ± 33.47 ） ng/L, （ 9. 24 ± 2. 15 ） /10^5, significantly higher than that after thearpy and experimental group which were （44. 34 ± 16. 32 ） ng,/L, （6. 31 ±1.83）/10^5 and （31.24 ± 8.43 ） ng/L, （ 3, 47 ± 1.32）/10^5 respectively. The IL-5 level was positively correlated with the CD34^＋ number pre-and post treatment in experimental group （ r = 0. 64, P 〈 0. 01 ; （ r = 0. 61 ,P 〈 0. 01 ）. The EOS number was positively correlated with the level of IL-5 （ r = 0. 64, P 〈 0. 01 ）. Conclusions IL-5 and CD34^＋ cells can be regarded as indicators to evaluate the therapeutic effect, The EOS,CD34^＋ cells and the level of IL-5 in the peripheral blood are correlated with the pathogenesis of AR, suggesting that there is a related path between the local nasal tissue of AR patients and the marrow.
