Lancet glob health:妊娠期患疟疾与死产的定量关联。

2017-09-27 qinqiyun MedSci原创

全球每年有260万例死产。而妊娠时患疟疾与死产的关联尚未完全量化。现Kerryn A Moore等人致力于量化这一关联,并评估疟疾的地方性对这一关联的影响。

全球每年有260万例死产。而妊娠时患疟疾与死产的关联尚未完全量化。现Kerryn A Moore等人致力于量化这一关联,并评估疟疾的疫情严重程度对这一关联的影响。

研究人员对已确诊的孕期疟疾和死产之间的联系进行系统性回顾。检索2017年2月28日前发表的以人口为基础的横断面、队列或病例对照研究(涉及死产或围产儿死亡的病例),以及研究孕期疟疾干预的随机对照试验。排除不是通过PCR、光学显微镜、快速诊断测试或组织学确诊的孕期疟疾。主要节点是死产。用Meta分析汇总孕期疟疾和死产的联系。用Meta回归评估疫情程度的影响。

本研究共纳入59个研究,995项纪录,包含141 415位女性和2287例死产。在分娩时外周血样中检测到恶性疟原虫会增加死产的概率(优势比[0R]1.81[95% CI 1.42-2.30];I2=26.1%;),在胎盘中检测到恶性疟原虫同样如此(OR 1.95[1.48-2.57];I2=33.6%)。在孕期检测到恶性疟疾并治疗也会增加死产的概率,但相对影响小一点(OR 1.47[95% CI 1.13-1.92])。分娩时检测到间日疟原虫也会增加死产的概率(2.81[0.77-10.22]),但妊娠期检测到并予以治疗,基本不影响死产的概率(1.09[0.76-1.57])。在低到中度疫情地区孕期疟疾和死产的关联性比高疫情的地区高两倍(OR的比1.96[95% CI 1.34-2.89])。假设所有患有疟疾的女性在分娩时仍然有寄生虫,那在撒哈拉以南非洲地区的1 059 700死产中,估计有20%是由于孕期的患恶性疟疾导致;若所有患疟疾的女性在孕期均得到治疗,那人口归因比例可下降至12%。

妊娠期患恶性疟和间日疟均会增加死产的风险。疟疾导致死产的风险随着疫情严重程度的减弱而增高。
