To ascertain whether the protective effect of smoking during preeclampsia (PE) can be visualized in the placenta.
The study cohort consisted of placentas (n = 523) from pregnancies complicated by PE, delivered at Karolinska University Hospital in Stockholm during the period 2000-2009. Of the women included in the study, 488 were non-smokers and 35 were smokers at first visit to maternity care. Outcome variables were placental infarctions and decidual arteriopathy.
Infarctions (affecting ≥5% of the placental tissue) were found in 15.6% of the placentas from non-smokers and in 25.7% of the placentas from smokers (OR 1.88: CI 0.84-4.16, p = 0.12). Decidual arteriopathy was found in 27.5% of the placentas from non-smokers and in 40.0% of the placentas from smokers (1.76: CI 0.87-3.56, p = 0.12). When diagnosed histopathologically, placental abruption was found in 15.4% among non-smokers and in 17.1% among smokers (1.14: CI 0.46-2.84, p = 0.98). Those differences did not show any statistical significance.
No significant differences concerning placental infarctions, decidual arteriopathy or abruption were found between preeclamptic placentas from non-smokers compared to smokers.
确定子痫前期(PE)期间吸烟的保护作用是否能在胎盘中显现出来。
研究队列包括2000年至2009年期间在斯德哥尔摩卡罗林斯卡大学医院分娩的、合并PE的妊娠胎盘(n = 523)。在纳入研究的女性中,488名在首次就诊于产科护理时为非吸烟者,35名是吸烟者。结局变量为胎盘梗死和蜕膜动脉病。
非吸烟者胎盘中有15.6%发现梗死(影响≥5%的胎盘组织),吸烟者胎盘中这一比例为25.7%(比值比1.88:可信区间0.84 - 4.16,p = 0.12)。非吸烟者胎盘中有27.5%发现蜕膜动脉病,吸烟者胎盘中这一比例为40.0%(1.76:可信区间0.87 - 3.56,p = 0.12)。经组织病理学诊断,非吸烟者中胎盘早剥的发生率为15.4%,吸烟者中为17.1%(1.14:可信区间0.46 - 2.84,p = 0.98)。这些差异均无统计学意义。
与吸烟者相比,非吸烟者的子痫前期胎盘在胎盘梗死、蜕膜动脉病或胎盘早剥方面未发现显著差异。
