J Allergy Clin Immunol:补充维生素D可治疗非特异性哮喘患者的嗜酸性气道炎症

2015-05-28 徐媛媛译 MedSci原创

低水平的维生素D与哮喘严重程度相关,气道重塑并且恶化率增加,尤其是在非特异性哮喘。减少类固醇响应或抗菌防御受损可能是潜在机制。在本项研究中,研究人员评估了补充维生素D对特异性哮喘患者嗜酸性粒细胞和嗜中性粒细胞气道炎症的影响。 在这项双盲、随机、安慰剂对照试验中,研究人员调查了维生素D3对嗜中性粒细胞(≥53%)和/或嗜酸性粒细胞(≥3%)气道炎症的特异性哮喘患者。在基线和9周后进行痰诱导。其它评

低水平的维生素D与哮喘严重程度相关,气道重塑并且恶化率增加,尤其是在非特异性哮喘。减少类固醇响应或抗菌防御受损可能是潜在机制。在本项研究中,研究人员评估了补充维生素D对特异性哮喘患者嗜酸性粒细胞和嗜中性粒细胞气道炎症的影响。

在这项双盲、随机、安慰剂对照试验中,研究人员调查了维生素D3对嗜中性粒细胞(≥53%)和/或嗜酸性粒细胞(≥3%)气道炎症的特异性哮喘患者。在基线和9周后进行痰诱导。其它评估手段包括问卷调查,血液样本和肺功能检测。

与安慰剂组相比,在所有组别中维生素D治疗对痰液中的嗜中性粒细胞或嗜酸性粒细胞无明显影响。对于痰液中的嗜酸性粒细胞,维生素D的作用似乎主要依赖于基线处的嗜酸性粒细胞水平(P=0.015)。对嗜酸性粒细胞水平≥26.2%或者更高(痰中嗜酸粒细胞中值>3%)的患者来说,使用维生素D治疗后,嗜酸性粒细胞的中值从41.0%降到11.8%,而安慰剂组患者嗜酸性粒细胞的中值从51.8%增加到63.6%(P=0.034)。维生素D治疗也可轻微改善哮喘控制问卷评分(P=0.08)。

补充维生素D可治疗非特异性哮喘患者的嗜酸性气道炎症,但对痰液中的嗜中性粒细胞没有影响。当然,对哮喘的控制影响较小。
