Maternal serum CA 125 is of prognostic value in patients with uterine bleeding in the detection of small-for-gestational-age neonates.

OBJECTIVE: The purpose of this study was to investigate whether maternal serum CA 125 determination in women with uterine bleeding has a prognostic value in the detection of women at risk for delivering a small-for-gestational-age neonate. STUDY DESIGN: The patients population consisted of women with uterine bleeding at a gestational age greater than 20 weeks. Patients with abruptio placentae, placenta previa, fetal distress and history of coagulopathy were excluded. Maternal serum CA 125 was measured at admission. Receiver operating characteristics curve analysis and logistic regression were used for statistical purposes. RESULTS: Fifty-nine women were enrolled into the study. Six of these had a small-for-gestational-age neonate, 8 had premature rupture of membranes and 33 delivered preterm. No relationship was found between maternal serum CA 125 concentrations and preterm delivery or PROM. Women who delivered a small-for-gestational-age infant (10.1%) had lower maternal serum CA 125 levels than those who delivered an appropriate-for-gestational-age infant (P < 0.02). Patients with uterine bleeding and serum CA 125 < or = 10 U/ml had a twofold risk to deliver a small-for-gestational-age neonate. Sensitivity, specificity, positive and negative predictive values were 66.6%, 79.2%, 26.6% and 95.4%, respectively. CONCLUSION: Our results show that a decreased maternal serum CA 125 concentration in women with uterine bleeding during the second half of pregnancy is of prognostic value in identifying those who will deliver a small-for-gestational-age infant.

Intraamniotic infection in patients with preterm labor and twin pregnancies.

BACKGROUND: Microbial invasion of the amniotic cavity plays a major role in the pathogenesis of preterm labor and delivery in singleton pregnancy. Nevertheless, this association is not well established among patients with multiple gestations. The purpose of our study was to explore the role of intraamniotic infection in the setting of twin pregnancies. METHODS: Consecutive women with twin gestations, intact membranes and preterm labor who underwent transabdominal amniocentesis under sonographic guidance. Amniotic fluid (AF) was retrieved from both sacs and cultured for aerobic and anaerobic microorganisms as well as for Mycoplasma species. Intraamniotic infection was defined as a positive AF culture for microorganisms. Mann Whitney U test or Student t-test or Fisher's exact test were utilized for analysis. RESULTS: Amniotic fluid was obtained from 74 patients. Sixty-eight women delivered prematurely (91.9%). Amniotic fluid culture results were positive for microorganisms in nine cases and all women with intraamniotic infection delivered prematurely as well as 59 (90.7%) patients with negative culture. Among the nine patients with intraamniotic infection, microorganisms were isolated from the presenting sac in five cases (55.6%), from both sacs in three patients (33.3%) and from the upper sac in the remaining case (11.1%). Patients with a positive AF culture had a more advanced cervical dilatation, a shorter interval amniocentesis-to-delivery and a higher incidence of clinical chorioamnionitis than those with a negative AF culture. CONCLUSIONS: The prevalence of intraamniotic infection and clinical and histological chorioamnionitis in twin pregnancies and preterm labor is similar to singleton pregnancies and preterm labor. Therefore, women with multiple gestations and preterm labor should be managed as singleton pregnancies.

Hyperemesis gravidarum: epidemiologic features, complications and outcome.

During the period of 4 years between 1985 and 1988, 190 patients suffering from hyperemesis gravidarum (HG) were hospitalized at the Soroka Medical Center. From the 190 patients, 164 were followed up throughout their pregnancies and delivered at our Medical Center. The epidemiology of HG as well as the incidence of maternal complications and pregnancy outcome were analyzed and compared with 209 controls. The incidence of HG in our patient population was 6.3/1000 live births. The patients in the study group had fewer pregnancies and deliveries and more spontaneous abortions in the past than in the control population. Premature contractions and vaginal bleeding during the first trimester were more common among women with HG. Other complications of pregnancy were no more common than among controls. Women with HG in their current pregnancy had a lower incidence of spontaneous abortions (3.1%) as compared with previously reported rates in the general population (15%). Perinatal outcome was no different in women with HG than in the controls. Women with severe HG did not have statistically significant differences in the incidence of pregnancy complications and their pregnancy outcome was the same as in those without severe HG.

[C-reactive protein as a marker of infection in women with preterm delivery].

There is a strong association between systemic and intrauterine infection and preterm delivery. C-reactive protein (CRP) is considered a nonspecific marker for intrauterine inflammation. We determined its blood level in 100 women who presented with preterm labor and intact membranes and delivered prematurely. CRP levels were used as a noninvasive marker for infection to compare clinical characteristics between women who delivered prematurely at 31-36 and 24-30 weeks of gestation. Women who delivered earlier than the 24th week of gestation had a higher rate of positive CRP levels than those who delivered later, 54% vs 24%, respectively (p < 0.0001). Moreover, women from the lower gestational age group with positive CRP levels had significantly different clinical characteristics than those in the same group but with negative CRP levels. There was a significant difference between Jewish and Bedouin women in cervical dilatation and time interval from hospitalization to delivery between those with positive CRP and those with negative CRP levels. We conclude that patients who delivered prematurely at 24-30 weeks had higher rates of an inflammatory etiology than women who also delivered prematurely, but at a more advanced gestational age.

Listeria monocytogenes. The role of transabdominal amniocentesis in febrile patients with preterm labor.

Two women with preterm labor and intraamniotic infection with Listeria Monocytogenes are presented. In both patients, the prenatal diagnosis of Listeriosis was made by transabdominal amniocentesis. The immediate prominent observation was meconium staining of the amniotic fluid. We propose that an amniocentesis should be performed in women with premature labor and fever. If the amniotic fluid is meconium stained and the Gram stain examination reveals Gram positive rods, Listeria Monocytogenes should be suspected and the patient should be treated accordingly until the culture results are obtained.

Changes in amniotic fluid concentrations of prostaglandins E2 and F2 alpha in women with preterm labor.

There is a paucity of data regarding the concentration of prostaglandins (PGs) in the amniotic fluid of women with preterm labor. The purpose of this study was to determine if preterm labor is associated with changes in amniotic fluid concentration of prostaglandins E2 and F2 alpha. Amniotic fluid was retrieved by transabdominal amniocentesis from women with preterm labor and intact membranes. Patients were classified into three groups according to the response to tocolysis and the presence or absence of intra-amniotic infection. PGE2 and PGF2 alpha were measured using specific and sensitive RIA kits. Amniotic fluid concentrations of PGE2 and PGF2 alpha were significantly higher in women with preterm labor and intra-amniotic infection than in women without infection, regardless of the response to tocolysis. These data suggest that both PGs are involved in the mechanism of preterm labor and may have prognostic value.
