维生素D辅助治疗儿童肺炎疗效的Meta分析

目的 系统评价维生素D辅助治疗儿童肺炎的疗效及安全性。方法 检索Cochrane Library、PubMed、EMbase、中国知网数据库、万方数据库及维普数据库建库至2019年8月的文献，收集关于维生素D辅助治疗儿童肺炎的随机对照试验。根据纳入与排除标准进行文献筛选、质量评价及资料提取，应用Revman 5.3软件对结局指标进行Meta分析。结果 最终纳入7篇文献，包括1 527例患儿，其中维生素D辅助治疗组762例，对照组765例。Meta分析结果显示维生素D辅助治疗不会影响儿童肺炎的疾病恢复时间（P=0.67）、住院时间（P=0.73）及退烧时间（P=0.43），也不会减少儿童肺炎的复发率（P=0.14）、不良反应率（P=0.20）及病死率（P=0.98）。结论 现有证据表明，辅以维生素D治疗儿童肺炎无明显效果。

Efficacy and safety of vitamin D as adjuvant therapy for childhood pneumonia: a Meta analysis

Objective To study the efficacy and safety of vitamin D as an adjuvant therapy for childhood pneumonia through a systematic review. Methods Cochrane Library, PubMed, EMbase, CNKI, Wanfang Data, and Weipu Data were searched for randomized controlled trials (RCTs) of vitamin D as the adjuvant therapy for childhood pneumonia published up to August 2019. Literature screening, quality assessment, and data extraction were performed based on inclusion and exclusion criteria. Revman 5.3 was used to perform the Meta analysis of outcome indicators. Results A total of 7 RCTs with 1 527 children were included, with 762 children in the vitamin D adjuvant therapy group and 765 children in the control group. The results of the Meta analysis showed that vitamin D adjuvant therapy had no effect on recovery time (P=0.67), length of hospital stay (P=0.73), and time to relief of fever (P=0.43). Furthermore, it did not reduce the recurrence rate (P=0.14), rate of adverse events (P=0.20), and mortality rate (P=0.98) of childhood pneumonia. Conclusions Current evidence shows that vitamin D adjuvant therapy has no marked efficacy in the treatment of childhood pneumonia.
