Preterm delivery, which is associated with infections during pregnancy, is common in sub-Saharan Africa. We enrolled 1,320 pregnant women into a randomized, controlled trial in Malawi to study whether preterm delivery and low birth weight (LBW) incidence can be reduced by intermittent preventive treatment of maternal malaria and reproductive tract infections. The participants received either sulfadoxine-pyrimethamine (SP) twice (controls), monthly SP, or monthly SP and two doses of azithromycin (AZI-SP). The incidence of preterm delivery was 17.9% in controls, 15.4% in the monthly SP group (P = 0.32), and 11.8% in AZI-SP group (risk ratio = 0.66, P = 0.01). Compared with controls, those in AZI-SP group had a risk ratio of 0.61 (P = 0.02) for LBW. Incidence of serious adverse events was low in all groups. In conclusion, the incidence of preterm delivery and LBW can in some conditions be reduced by treating pregnant women with monthly SP and two azithromycin doses.
早产与怀孕期间的感染有关,在撒哈拉以南非洲很常见。我们在马拉维招募了 1320 名孕妇参加一项随机对照试验,以研究间歇性预防母亲疟疾和生殖道感染是否可以降低早产和低出生体重(LBW)的发生率。参与者接受了磺胺多辛-乙胺嘧啶(SP)两次(对照组)、每月 SP 或每月 SP 和两剂阿奇霉素(AZI-SP)。对照组早产发生率为 17.9%,每月 SP 组为 15.4%(P=0.32),AZI-SP 组为 11.8%(风险比=0.66,P=0.01)。与对照组相比,AZI-SP 组的 LBW 风险比为 0.61(P=0.02)。所有组的严重不良事件发生率均较低。总之,在某些情况下,每月 SP 和两剂阿奇霉素治疗孕妇可以降低早产和 LBW 的发生率。
