To evaluate pregnancy outcome and thrombophilia frequency in women with recurrent
fetal death.
Evaluation of obstetric outcomes in a retrospective cohort of pregnant women with
recurrent stillbirth after the 20th week, from 2001 to 2013.
Antithrombin activity, protein C and S activity, factor V Leiden, prothrombin gene
mutation and antiphospholipid syndrome were analyzed.
We included 20 patients who had recurrent fetal death. Thrombophilia were found
in 11 of them, 7 diagnosed with antiphospholipid syndrome, 3 with protein S
deficiency and 1 with prothrombin gene mutation. All of them were treated with
subcutaneous heparin (unfractionated heparin or enoxaparina) and 14 of them with
acetylsalicylic acid (AAS) during pregnancy. Obstetric complications occurred in
15 patients and included: intrauterine fetal growth restriction (25%), placenta
previa (15%), reduced amniotic fluid index (25%), severe preeclampsia (10%), fetal
distress (5%), and stillbirth (5%). The mean gestational age at delivery was
35.8±3.7 weeks and newborn weight averaged 2,417.3±666.2 g.
Thrombophilia screening should be performed in all pregnant women with recurrent
fetal death after the 20th week as a way to identify possible causal
factors suitable for treatment.

PURPOSE: To analyze the results of assessment of fetal well-being in pregnancies complicated by moderate or severe maternal thrombocytopenia. METHODS: Data from April 2001 to July 2011 of 96 women with a diagnosis of thrombocytopenia in pregnancy were retrospectively analyzed. We analyzed the following tests performed during the antepartum period for fetal assessment: cardiotocography, fetal biophysical profile, amniotic fluid index and umbilical artery Doppler velocimetry. RESULTS: A total of 96 pregnancies with the following diagnoses were analyzed: gestational thrombocytopenia (n=37, 38.5%) hypersplenism (n=32, 33.3%), immune thrombocytopenic purpura (ITP, n=14, 14.6%), secondary immune thrombocytopenia (n=6, 6.3%), bone marrow aplasia (n=3, 3.1%), and others (n=4, 4.1%). Cardiotocography showed normal results in 94% of cases, a fetal biophysical profile with an index of 8 or 10 in 96.9% and an amniotic fluid index >5.0 cm in 89.6%. Doppler umbilical artery velocimetry showed normal results in 96.9% of cases. In the analysis of the major groups of thrombocytopenia, the diagnosis of oligohydramnios was found to be significantly more frequent in the group with ITP (28.6%) compared to the other groups (gestational thrombocytopenia: 5.4% and hypersplenism: 9.4%, p=0.04). CONCLUSIONS: This study indicates that in pregnancies complicated by moderate or severe maternal thrombocytopenia, even though the fetal well-being remains preserved in most cases, fetal surveillance is important in pregnant women with ITP, with emphasis on amniotic fluid volume evaluation due to its association with oligohydramnios.

PURPOSE: To describe the maternal and perinatal outcomes of pregnant women diagnosed with leukemia who were followed up for prenatal care and delivery at a university hospital. METHODS: A retrospective study of the period from 2001 to 2011, which included 16 pregnant women with a diagnosis of leukemia followed by antenatal care specialists in hematological diseases and pregnancy. For acute leukemia diagnosed after the first trimester, the recommendation was to perform chemotherapy despite the current pregnancy. For chronic leukemia, patients who were controlled in hematological terms were maintained without medication during pregnancy, or chemotherapy was introduced after the first trimester. We analyzed the maternal and perinatal outcome. RESULTS: Acute lymphoblastic leukemia (ALL) was diagnosed in five cases (31.3%), acute myeloid leukemia (AML) in two cases (12.5%) and chronic myeloid leukemia (CML) in nine cases (56.3%). Of the cases of acute leukemia, two (28.6%) were diagnosed in the first trimester, two (28.6%) in the second and three (42.9%) in the third. Two patients with ALL diagnosed in the first trimester opted for therapeutic abortion. Four patients with acute leukemia received chemotherapy during pregnancy, with a diagnosis established after the 20th week. In one case of ALL with a late diagnosis (30 weeks), chemotherapy was started after delivery. All pregnant women with acute leukemia developed anemia and thrombocytopenia, and four (57.1%) developed febrile neutropenia. Of nine pregnant women with CML, four were treated with imatinib mesylate when they became pregnant, with treatment being interrupted in the first trimester in three of them and in the second trimester in one. During pregnancy, three patients (33.3%) required no chemotherapy after discontinuation of imatinib, and six (66.7%) were treated with the following drugs: interferon (n=5) and/or hydroxyurea (n=3 ). In the group of pregnant women with CML, anemia occurred in four (44.4%) cases and thrombocytopenia in one (11.1%). The perinatal outcomes of pregnancies complicated by acute leukemia were as follows: mean gestational age at delivery was 32 weeks (standard deviation - SD=4.4) and the mean birth weight was 1476 g (SD=657 g), there were 2 (40.0%) perinatal deaths (a fetal one and a neonatal one). In pregnancies complicated by CML, the mean gestational age at delivery was 37.6 weeks (SD=1.1) and the mean birth weight was 2870 g (SD=516 g). There was no perinatal death and no fetal abnormality was detected. CONCLUSIONS: Maternal and fetal morbidity is high in pregnancies complicated by acute leukemia. Whereas, in pregnancies complicated by CML, the maternal and fetal prognosis appears to be more favorable, with greater ease in management of complications.

PURPOSE: the aim of this study was to describe perinatal and maternal outcomes of pregnancies complicated by sickle cell disease (SCD), comparing to pregnancies of women with sickle cell trait (SCT). METHODS: this was a retrospective cohort study, covering the period from March 2001 to April 2008, which included all pregnant women with SCD (n=42) followed up at a university hospital in the Southeast region of Brazil. The maternal and perinatal outcomes were compared to those of pregnant women with SCT (n=56) who were followed up at the same service. RESULTS:SCD-SS was diagnosed in 42 (82.4%) pregnant women and SC in 9 (17.6%). Mean (±SD) maternal age was significantly lower in the SCD group (26.0 years) compared to SCT women (28.7±7.1 years; p=0.018). The following maternal complications were more common among women with SCD in comparison to SCT: urinary tract infection (25.5 versus 8.9%; p=0.04), pneumonia (23.5 versus 1.8%; p=0.002), pulmonary hypertension (15.7 versus 0%; p=0.002), and blood transfusion during delivery or postpartum (33.3 versus 5.4%; p=0.001). Adverse perinatal outcome was more frequent in the SCD group compared to the SCT group: prematurity (49 versus 25%, p=0.01); mean gestational age at delivery (35.2 versus 37.9 weeks, p<0.001); fetal distress (56.9 versus 28.6%, p=0.006); birth weight <2,500 g (62.7 versus 17.9%, p<0.001); mean birth weight (2,183 versus 2,923 g, p<0.001), and small for gestational age infants (29.4 versus 10.7%, p=0.029). Two maternal deaths (3.9%) occurred in the group with SCD. CONCLUSION: Pregnant women with SCD are at greater risk for maternal morbidity and for adverse perinatal outcomes than women with SCT.

PURPOSES: to evaluate the influence of maternal hemoglobin (Hb) levels in the patterns of fetal heart rate (FHR) and in the fetal biophysical profile (FBP) in term gestations. METHODS: pregnant women with anemia (Hb<11.0 g/dL) were prospectively evaluated between the 36th and the 40th week of gestation, from January 2008 to March 2009. The Control Group was composed of term and healthy pregnant women, with normal values of hemoglobin (Hb>11,0 g/dL). Cases of anomalies or fetal growing restrictions were excluded. The FHR evaluation was performed by computerized cardiotocography (8002 System-Sonicaid), and by record analysis during 30 minutes of exam. The FBP was done in all the patients. Student's, χ2 and Fisher's exact tests were used, with 0.05 significance level. RESULTS: The average of maternal Hb in the group with anemia (n=18) was 9.4 g/dL (DP=1.4 g/dL), and in the control group, 12.4g/dL (DP=1.3 g/dL). There has been no significant mean differences between groups concerning the cardiotocography parameters, respectively: basal FHR(131.3 versus 133.7 bpm, p=0.5), FHR accelerations > 10b pm (7.9 versus 8.2, p=0.866), FHR accelerations > 15 bpm (5.2 versus. 5.4, p=0.9), episodes of high variation of the FHR (17.1 versus 15.5 min, p=0,5), episodes of variation of the FHR (4.4 versus 3.6 min, p=06), and short term variation (10.5 versus 10.9 ms, p=0.5). In both groups, all patients presented normal FBP. CONCLUSIONS: this study suggests that light or moderate maternal anemia, without other maternal or fetal comorbidity, is not associated with abnormalities in the parameters of fetal biophysical profile and of the FHR analyzed by computerized cardiotocography.
