尿路感染(UTI)是临床中常见的问题。呋喃妥因用于预防UTI已经有60余年,其有效性和安全性如何呢?2017年6月,发表在《Clin Microbiol Infect.》的一项系统评价和荟萃分析对此进行调查。

目的:呋喃妥因用于预防UTI已经有60余年。研究者开展了一项系统评价和荟萃分析,以评价其预防UTI的有效性和安全性。

方法:研究者对发表于1946年至2015年,评价呋喃妥因预防人UTI的对照试验开展了一项系统评价。研究者进一步评价了评价呋喃妥因毒性的基于人群层面的队列研究。

结果:涉及3052例患者的26项对照试验符合有效性和毒性相关系统评价和荟萃分析的纳入标准,确定了16项基于人群层面的队列研究用于毒性评价。总体质量较差,所有研究的各类偏倚风险增加。与不预防比较,呋喃妥因可以有效预防UTI(支持呋喃妥因的风险比,0.38,95% CI 0.30~0.48)。呋喃妥因的有效性优于马尿酸乌洛托品,与其他抗菌药相当。与使用其他抗菌药的患者相比,使用呋喃妥因的患者的非严重不良影响风险增加2.24(95% CI 1.77~2.83)。在所有对照试验中,仅有1例患者经历严重不良影响(间质性肺炎)。队列研究报告严重不良影响的频率为0.02~1.5每1000例呋喃妥因使用者。

结论:呋喃妥因可以有效预防UTI。其使用或与非严重不良影响增加相关;严重不良影响发生不频繁。严重毒性风险似乎随着呋喃妥因预防疗程的增加而增加。
