OBJECTIVE: To examine the relationship of the amniotic, and maternal infiammatory responses and decreased amniotic fluid in patients with preterm PROM. METHODS: Fifty three patients with preterm PROM in singleton pregnancy who delivered preterm neonates (gestational age<35 weeks) within 3 days of amniocentesis were included. Amniotic fluid index(AFI) was measured by transabdominal ultrasonography at amniocentesis. Amniotic fluid was cultured far aerobic and anaerobic bacteria and mycoplasma. The intensity of the inflammatory response was evaluated by clinical and histologic chorioamnionitis. The intensity of fetal hypoxia was evaluated by 1 min Apgar score, 5 min Apgar score, and pH of cord blood at birth. RESULTS: The prevalence of oligohydramnios, which was defined when measured AFI was equal or less than 5.0, was 34% (18/53). The prevalence of positive amniotic fluid culture was 45% (24/53) and that of patients with was significantly higher than that of patients without oligohydramnios (78% [14/l8] vs 29% [10/35], p<0.01). Intrauterine inflammatory response was significantly stronger in patients with oligohydratnnios than in patients with adequate amniotic fluid (pathologic chorioamnionitis 100% [l6/16] vs 63% [19/30], clinical chorioamnionitis 39% [7/18] vs 6% [2/35]; p<0.01 for each). However, no significant difference was found in the intensity of fetal hypoxia (I min Apgar score <7 67% [12/18] vs 66% [23/35], 5 min Apgar score <7 39% [7/l8] vs 26% [9/35], pH of cord artery blood at birth 7.27+0.13 vs 7.22+0.13; p>O.I, for each). CONCLUSION: Oligohydramnios in patients with preterm PROM is strongly pedictive for positive amniotic fluid culture, and is associated with a robust host response in amniotic, and maternal cornpartments, but not with fetal hypoxia.

OBJECTIVE: To evaluate the maternal complications and perinatal outcomes in twin pre-gnancies with one fetal demise PATIENTS: From January 1990 to December 1996, 20 twin pregnancies with single fetal death were observed in Seoul National University Hospital : in 6 cases(group 1) between 20 ~26 weeks and in 14 cases(group 2) after 26 weeks gestation by gestational age of fetal death ; in 7 cases of monochorionic and in 13 cases of dichorionic placentation. RESULTS: The incidence of one fetal death was 5.4% in twin pregnancy. Diagnosis-to- delivery interval of group 1 was longer than group 2(61.0 days : 8.9 days). So it was thou- ght that the gestational age of delivery in group 1 was not always earlier than in group 2. And other parameters(chorionicity, preterm delivery, cesarean section, coagulopathy, IUGR, perinatal mortality, neurologic sequelae, IVH) didn't show the statistical differences between group 1 and group 2. According to chorionicity, it seemed that the perinatal mortality rate of monochorionic group was higher than dichorionic(86% : 62%) and that cesarean section rate was higher in dichorionic group(54% : 14%). But there were no statistical significances between two gruops. All other parameters also didn't show differences statistically. CONCLUSION: We fail to demonstrate that monochorionic placentation is associated with increased risks for the survivor in twin pregnancies of single fetal demise. It may be part- ially explained due to small numbers of cases in this study.

OBJECTIVE: To evaluate the relationship between amniotic fluid interleukin-8 and the presence, severity and pattern of acute inflammatory lesions in the placenta delivered after preterm labor with intact membranes. METHODS: The relationship between placental histologic finding and amniotic fluid interleukin-8 was examined in 46 consecutive patients who were admitted with the diagnosis of preterm labor with intact membranes and who delivered singleton gestations within 5 days. RESULTS: The prevalence of acute histologic chorioamnionitis was 63.0%(29/46) and that of positive amniotic fluid culture was 17.4%(8/46). The most frequent site of histologic inflammation was chorion-decidua(56.5%, 26/46). The median amniotic fluid interleukin-8 increased significantly according to the presence and higher severity of inflammation in each type of placental section (p<0.05 for each). Three patterns of inflammation were identified in chorion-decidua: non-marginating, marginating, and mixed. Median amniotic fluid interleukin-8 and the rate of severe histologic chorioamnionitis (grade> or = 4) increased significantly in the order of non-marginating, marginating, and mixed (p<0.05 for each). CONCLUSION: Both the presence and greater severity of acute histologic chorioamnionitis are associated with an elevated amniotic fluid interleukin-8. A marginating and mixed pattern of inflammation are associated with a higher amniotic fluid interleukin-8. Amniotic fluid interleukin-8 is a reliable prenatal marker of histologic chorioamnionitis.
