摘要 目的探讨维生素D对慢性阻塞性肺疾病(COPD)患者急性加重率及病死率的影响。方法以随机区组法将150例COPD稳定期合并维生素D缺乏患者分为常规剂量组、大剂量组及安慰剂组,各50例,分别给予安慰剂,阿法骨化醇400 U/d口服及1 000 U/d口服。比较患者治疗前后肺通气功能指标水平、急性加重率及病死率等。结果常规剂量组和大剂量组患者治疗后肺功指标水平均优于治疗前(均<0.05),大剂量组优于常规剂量组(<0.05),安慰剂组治疗前后肺功能指标差异无统计学意义(>0.05);大剂量组与安慰剂组患者急性加重率低于安慰剂组(均<0.05),而大剂量组低于常规剂量组(<0.05);3组患者病死率差异无统计学意义(>0.05)。结论补充维生素可使COPD患者获得明显临床收益,且大剂量应用更有助于改善肺部通气功能,避免COPD急性加重发生。
