Of 119 full-term pregnant subjects studied from October, 1995 to March, 1996, 79 hadpreeclampsia(severe; 43, mild; 36) and 40 were normotensive controls. The plasma fibronectinlevels of each subject were assayed by turbidometric immunoassy(Boehringer Mannheim).The objective of this study was to evaluate the relationship of plasma fibronectin withpreeclampsia as a marker for vascular injury.The results were as follows:1. There were significant differences of plasma fibronectin values among the normotensivepregnancy, mild preeclampsia and severe preeclampsia. Within each group of patients,plasm a fibronectin values were 101.7 +/- 59.4 ng/ml and 249.7 +/- 96.3 ng/ml and 329.2 +/- 169.5 ng/ml, respectively (p < 0.001).2. Plasma fibronectin values had positive correlations with severity of preeclampsia,proteinuria, diastlic blood pressure and systolic blood pressure, but negative correlationswith birth weight and platelet count(p < 0.001).3. When the severity of proteinuria on preeclampsia were +1, +2, and +3 or more,plasma fibr onectin values revealed 246.0 +/- 93.3 ng/ml, 342.3 +/- 185.1 ng/ml and 345.0 +/- 168.1ng/ml, respectively and there were significant differences among three groups.4. To verify the variables correlated with plasma fibronectin by using mutiple regressionanalysis, the only variable which was selected significantly was the severity of preeclampsia(r(2) : 0.529).5. With receiver operating characteristic(ROC) curve analysis of the relationship betweenplasma fibronectin values and preeclampsia, if cut off value was selected at the levelof 175ng/ml or more, the sensitivity for diagnosis of preeclampsia was 87.3%, specificity90.0%, positive predictive value 94.5%, and negative predictive value 78.3%, respectively.

Objective: To explore the associations between blood pressure trajectories during pregnancy and risk of future pre-eclampsia in a large cohort enrolling pregnant women at gestational age of ~12 weeks from community hospitals in Tianjin. Latent class growth modeling (LCGM) was used to model the blood pressure trajectories. Methods: This was a large prospective cohort study. The study enrolled pregnant women of ~12 weeks of gestation in 19 community hospitals in Tianjin from November 1, 2016 to May 30, 2018. We obtained related information during 5 antepartum examinations before gestational week 28, i.e., week 12, week 16, week 20, week 24 and week 28. LCGM was used to model longitudinal systolic (SBP) and diastolic blood pressure (DBP) trajectories. For the association study, the predictors were set as SBP and DBP trajectory membership (built separately), the outcome was defined as the occurrence of preeclampsia after 28 weeks of gestation. Results: A total of 5 809 cases with known pregnant outcomes were documented. After excluding 249 cases per exclusion criteria, 5 560 cases with singleton pregnancy were included for final analysis. There were 128 cases preeclampsia and 106 cases gestational hypertension in this cohort. Univariate logistic regression and multivariate logistic regression showed the higher baseline SBP level and DBP level were related with increased risk of preeclampsia. Four distinctive SBP trajectories and DBP trajectories from 12 weeks to 28 weeks of gestation were identified by LCGM. After controlling for potential confounders (baseline BMI, being primipara or not, white blood cell counts, hemoglobin level, platelet counts and alanine aminotransferase level), the OR for SBP latent classification trajectory_ 4 was 4.023 (95%CI: 2.368 to 6.835, P<0.001), and the OR for SBP latent classification trajectory_3 was 1.854 (95%CI: 1.223 to 2.811, P=0.004). Logistic regression showed that: using the DBP latent classification trajectory_1 as the reference group, the OR for DBP latent classification trajectory_4 was 4.100 (95%CI: 2.571 to 6.538, P<0.001), and 2.632 (95%CI: 1.570 to 4.414, P<0.001) for DBP latent classification trajectory_2. After controlling for potential confounders (baseline BMI, being primipara or not, white blood cell counts, hemoglobin level, platelet counts and alanine aminotransferase level), the OR for DBP_traj_4 was 2.527 (95%CI: 1.534 to 4.162, P<0.001), and the OR for DBP_traj_3 was 1.297 (95%CI: 0.790 to 2.128, P=0.303), and 2.238 (95%CI: 1.328 to 3.772, P=0.002) for DBP_traj_2. Therefore, BP trajectories from 12 weeks to 28 weeks identified by LCGM served as novel risk factors that independently associated with the occurrence of preeclampsia. Receiver operating characteristic (ROC) curve analysis showed incremental diagnostic performance by combing baseline blood pressure levels with blood pressure trajectories. Conclusion: By applying LCGM, we for the first time identified distinctive BP trajectories from gestational week 12 to 28, which can independently predict the development of preeclampsia after 28 weeks of gestation.

Thrombotic thrombocytopenic purpura (TTP) is quiet rare, with 1 of 25,000 delivery and complicating pregnancy is associated with high maternal mortality and long-term morbidity. Unfortunately the clinical appearance of thrombotic thrombocytopenic purpura is similar with the syndrome of hemolysis, elevated liver enzyme, and low platelet (HELLP), but the treatment of this differs from that of the HELLP syndrome or acute fatty liver of pregnancy, therefore accurate diagnosis is essential for optimal therapy. The survival of this disorder has been improved due to aggressive treatment with plasma transfusion or plasmapheresis. We have experienced a case of thrombotic thrombocytopenic purpura confused with HELLP syndrome of preeclampsia, so we report it with a brief review of literature.

Objectives: To determine whether the clinical aspect of aplastic anemia is influenced by pregnancy. METHODS: We reviewed 37 cases of pregnant aplastic anemia patients during Jan. 1989 to Dec. 1998, and examined age, parity, progress of pregnancy, termination methods, obstetrics & neonatal complications, hematologic change, and treatment modality by medical records. RESULTS: According to onset of disease, patients were divided into pre-pregnant diagnosed group(n=12) and during-pregnancy diagnosed group(n=25). Mean age of diagnosis was 29.4yr, 89.2% were nulliparous, and 51.4% were severe aplastic anemic patients. All patients underwent 50 pregnancy. Mean gestational period was 37wks, birth weight was 2569gram, and, except in 7 cases of abortion, 43 cases were delivered transvaginally or transabdominally(51.2% vs. 48.8%). Preeclampsia, eclampsia, preterm labor, restricted growth, and distress were complicated and decreased hemoglobin, hematocrit, reticulocyte, platelet were reversed after termination in pregnancy associated group. Treatment modality during pregnancy included transfusion, steroid, anti-lymphocytic globulin, anti-thymocytic globulin and IVGV, and remission rate was 45.5% in pregnancy associated group. CONCLUSION: We concluded that pregnancy is associated with aplastic anemia as a high risk factor, and intensive treatment is needed.

OBJECTIVETo investigate the expression of placenta-derived RASSF1A gene in maternal plasma during first and second trimesters, and to explore its value for the prediction of pre-eclampsia.

METHODSFor 325 pregnant women of the first trimester, free DNA of plasma samples was extracted at 7-12, 13-18, and 19-24 gestational weeks, respectively. Methylation-sensitive restriction enzyme digestion followed by fluorescence quantitative PCR (MSRE+ PCR) was employed for analyzing the concentrations of hypermethylated RASSF1A gene. Blood pressure, proteinuria and clinical feature were monitored at the same time. Those who had subsequently developed pre-eclampsia were selected as the pre-eclamptic group, 30 normal pregnant women were selected as the control group. Hypermethylated RASSF1A gene in maternal plasma was retrospectively analyzed. The relationship between clinical classification, type of pre-eclampsia and concentrations of the gene were further analyzed.

RESULTSTwenty-six out of the 325 pregnant women developed pre-eclampsia as their only complication. At 13-18 gestational weeks, the mean concentrations of fetus-specific RASSF1A sequences were 141.62 copies/mL in maternal plasma of pre-eclamptic pregnancies, which was significantly greater than that of the controls (98.90 copies/mL). Fetus-derived RASSF1A levels were 2.03 fold higher in pre-eclamptic subjects than controls at 19-24 gestational weeks. There was a significant difference in the level of hypermethylated RASSF1A gene between the mild and severe pre-clamptic subjects at 13-24 gestational weeks (P< 0.05). The concentrations of the sequences were significantly higher in early-onset severe pre-eclampsia than late-onset severe pre-eclampsia at 19-24 gestational weeks (P< 0.05).

CONCLUSIONAltered expression of hypermethylated RASSF1A gene may be detected in maternal plasma during second trimester, which has important significance for early prediction of pre-eclampsia.

Paraganglioma in pregnancy is an extremely rare condition and its diagnosis is often delayed because the clinical symptoms can mimic those of preeclampsia or gestational hypertension. Here, we report the case of a 32-year-old, gravida 2, para 1 woman who presented with severe headache, palpitation, and sweating at 37 weeks' gestation. Although emergent cesarean section was performed on the assumption of severe preeclampsia, blood pressure fluctuated and heart rate remained tachycardiac. We suspected that she might have thromboembolic lesion in the chest or pheochromocytoma. Chest and abdominal computed tomography revealed a 4 cm mass in the left para-aortic space. Serum and urinary catecholamine levels were found to be significantly increased. She underwent laparoscopic mass removal and the pathology confirmed paraganglioma. When typical paroxysmal hypertension is accompanied by headache, palpitation, and sweating during pregnancy, adrenal tumors should be considered.

OBJECTIVE: Gestational diabetes mellitus is defined as carbohydrate intolerance of variable severity first diagnosed during pregnancy. It is associated with adverse outcomes of pregnancy including obstetrical complications such as increased rate of cesarean sections, preeclampsia, and birth trauma, and perinatal morbidities, such as macrosomia, hypoglycemia, hypocalcemia, and hyperbilirubinemia. Therefore, screening for gestational diabetes mellitus and early diagnosis of this condition allows intervention to be carried out, thereby, the reduction of the untoward effects mentioned above can be minimized. METHODS: Screening for abnormal glucose metabolism was carried out in 489 pregnant women. A 50-g oral glucose load without regard to time of day or last meal, and a 1-hour plasma glucose determination with a threshold of 140mg/dl were used as a glucose screening test(GST). Patients with an abnormal GST underwent an oral glucose tolerance test(GTT). RESULTS: The overall incidence of gestational diabetes was 2.7%. The occurrence of this disorder was significantly related to the age of pregnant women, parity, or the presence of risk factors for gestational diabetes and obesity(Body Mass Index> or =26kg/m2). CONCLUSION: This study suggests that Korean pregnant women should be screened for gestational diabetes.

Intracerebral hemorrhage (ICH) is one of very dangerous complications of preeclampsia/eclampsia. We experienced postoperative ICH in a 39-year-old woman with preeclampsia and HELLP syndrome. The paturient complained severe headache and upper abdominal pain with nausea and vomiting. Her initial blood pressure was 190/120 mmHg and her heart rate was 80 beat/min. The diagnosis of preeclampsia with HELLP syndrome was confirmed by the severe hypertension and the laboratory findings. She was drowsy at the emergency room but she lost consciousness when transferring to the operation room. Caesarean section was done under general anesthesia. After the operation she could not recover self-respiration and consciousness. Her brain CT showed ICH in the basal ganglia with intraventricular hemorrhage and severe brain edema. She expired one the 5 th post operative day due to brain death and multiple organ failure. Early diagnosis is the key to treating ICH.

Hypertensive encephalopathy is usually defined as malignant hypertension associated with central nervous system abnormalities such as headache, seizure, hypertension, altered consciousness, increased intracranial pressure, and retinopathy. The pathogenesis of hypertensive encephalopathy is uncompletely understood, although it seems to be related to hypertensive cerebrovascular endothelial dysfunction, disruption of the blood-brain barrier with increased permeability, cerebral edema, and microhemorrhage formation. Magnetic resonance imaging shows a characteristic posterior leukoencephalopathy that predominantly affects the white matter of the parieto-occipital regions. Hypertensive encephalopathy is a rare manifestation of hypertensive emergency that requires proper diagnosis and management to avoid a irreversible brain damage. We report a patient who developed hypertensive encephalopathy after cesarean section without preeclampsia or chronic hypertension and a case presented with a brief review of the literatures.

Diabetes in pregnancy is associated with higher rates of miscarriage, pre-eclampsia, preterm labor, and fetal malformation. To prevent these obstetric and perinatal complications, women with diabetes have to control levels of blood sugar, both prior to and during pregnancy. Thus, individualized medical nutrition therapy for each stage of pregnancy is essential. We provided in-depth medical nutrition therapy to a 38-year-old pregnant woman with diabetes at all stages of pregnancy up to delivery. She underwent radiation therapy after surgery for breast cancer and was diagnosed with diabetes. At the time of diagnosis, her glycated hemoglobin level was 8.3% and she was planning her pregnancy. She started taking an oral hypoglycemic agent and received education regarding the management of diabetes and preconception care. She became pregnant while maintaining a glycated hemoglobin level of less than 6%. We provided education program for diabetes management during the pregnancy, together with insulin therapy. She experienced weight loss and ketones were detected; furthermore, she was taking in less than the recommended amount of foods for the regulation of blood sugar levels. By giving emotional support, we continued the counseling and achieved not only glycemic control but also instilled an appreciation of the importance of appropriate weight gain and coping with difficulties. Through careful diabetes management, the woman had a successful outcome for her pregnancy, other than entering preterm labor at 34 weeks. This study implicated that the important things in medical nutrition therapy for pregnant women with diabetes are frequent follow-up care and emotional approach through the pregnancy process.
