2017年9月,发表在《Chest》的一项由卡塔尔和美国科学家进行的研究比较了快速和维持维生素D补充预防维生素D不足的哮喘儿童患者哮喘发作的效果。

背景:维生素D是否减少儿童哮喘的临床重要发作仍不清楚。研究者通过分析基线维生素D水平,比较了快速与维持维生素D补充。

方法:对与因中至重度哮喘发作前往急诊(ED),且维生素D水平≤25 ng/mL的儿童进行设盲随机,并开放给药:IM+口服(后者每天给药)疗法或每天仅口服给药,随访12个月。主要结局为患者由于哮喘发作而进行的非计划就医,通过两种方式进行考察:发作的累积比例,以及平均发作频率。作为营养研究,研究者通过基线维生素D水平的四分位间距,分析了治疗组,收集入组后3、6、9和12个月时的重复水平和临床观察。

结果:IM+口服队列116例患者vs仅口服队列115例患者的平均(SD)基线水平相似:15.1(5.4)vs 15.8(5.2)ng/mL(范围,3~25 ng/mL)。整个12个月的观察期间,主要结局没有差异。然而,在最初3个月,快速IM+口服补充显着降低了基线水平在3~11 ng/mL的儿童因哮喘发作而进行的无计划就医:与仅口服相比,3个月IM+口服队列的相对发作率为0.48(95% CI,0.28~0.89;P=0.008);分析每例儿童的平均发作频率,相对率为0.36(95% CI,0.13~0.87;P=0.017)。此外,两组无显着差异。

结论:与维持维生素D补充相比,维生素D水平最低的儿童快速补充维生素D可以降低短期而非长期哮喘发作。
