ABSTRACT

Several studies examined the perinatal outcome after PPROM in twin compared with singleton gestations. Mercer et al.1 found no significant differences in infectious morbidity in terms of chorioamnionitis and postpartum fever between twin and singleton gestations despite the presence of an intact amniotic sac in the second twin. In contrast, Myles et al.2 observed a somewhat higher incidence of chorioamnionitis in singleton pregnancies and explained this finding by the longer latency period among singletons – as was also observed by Bianco et al.3 and Mizrahi et al.4 The latter group compared perinatal outcomes in spontaneously conceived 435 sets of twins and 4754 singletons born preterm. Twin gestation had significantly lower rates of PPROM and clinical chorioamnionitis (12.2% vs.17.3%, and 1.8% vs. 5.2%, respectively).
