SummaryNeopterin (serum. urine) and other markers of macrophage activation (lL-1 IL-6, TNF alpha) were compared in preeclamptic patients and healthy pregnant controls. The prepartal urine neopterin median in preeclampsia (337 μmol/mol creat.) was 33% higher than that of healthy pregnant controls (253 μmol/mol creat.). There was no statistically significant difference between the groups (p = 0.08). In plasma there were no statistically significant differences in cytokine concentrations between healthy pregnant and nonpregnant controls with the exception of neopterin. that showed higher values in pregnant women (p = O.OO4). Elevated levels of IL-6. TNF-alpha and neopterin were observed in hypertensive women. Differences to healthy pregnant controls were statistically significant for IL-6 (p = 0.008). TNF-alpha (p = 0.009) and neopterin (p=0.04) and were more pronounced in severe forms of the disease. These three parameters of monocytic origin showed positive significant correlations amongst each other. A participation of macrophages in the pathomechanism of hypertensive disorders of pregnancy can thus be assumed.

Background: A major challenge in obstetrics is early identification of hypertensive disorders of pregnancy (HDP). This study was performed to determine the association between elevated maternal serum β-hCG levels and HDP, the correlation between serum β-hCG level and severity of preeclampsia and to determine the value of serum β-hCG level as a diagnostic marker for early diagnosis of HDP.Methods: This was a hospital based observational study conducted in the department of obstetrics and gynecology, Rajendra Institute of Medical Sciences, Ranchi on 375 pregnant women with period of gestation more than 20 weeks, including 250 pregnant women with HDP as study group and 125 normotensive pregnant women as controls. Serum β-hCG concentration was measured and its level was compared between two groups.Results: The maternal mean serum β-hCG levels (51161.08±30038.21 IU/L) of study group of HDP were higher than the normotensive control group (17603.23±16748.21 IU/L). In non-severe preeclampsia, the mean serum levels were 36417.32±23876.74 IU/L while in severe preeclampsia, 60030.34±28771.31 IU/L. There was statistically significant difference (p<0.001) with higher levels in early onset preeclamptic mothers than late onset preeclampsia. The cut-off point of β-hCG for predicting HDP was 32077 IU/L with sensitivity of 65% and specificity of 86%.Conclusions: Serum β-hCG level is higher in HDP when compared to normotensive women. Higher levels of β-hCG are associated with increasing severity of hypertensive disorders of pregnancy. The utility of serum β-hCG as a diagnostic test is limited because of low sensitivity and difficulty in deciding the cut-off value.

Introduction: Hypertensive disorders of pregnancy (HDP) are the most common complications observed during pregnancy and are a leading cause of maternal and perinatal morbidity and mortality. Thyroid hormone abnormalities are prevalent in females of reproductive age group. However, the relation between thyroid hormones and hypertensive pregnant women remains unclear. This study aims to assess the status of thyroid hormone abnormalities in patients with HDP. Materials and Methods: This is a case-control study conducted for one year in Karnali Province Hospital and Deuti Hospital, Surkhet, Nepal. Thirty hypertensive patients with singleton pregnancies in the third trimester were taken as case and 30 healthy normotensive singleton pregnant women as control and their thyroid hormone parameters were compared. Statistical analysis was done using SPSS version 21. Results: The mean gestational age of recruited study subjects and control were 37.00 ± 3.04 weeks and 35.70±3.83 weeks (p>0.05). The mean value of TSH was significantly higher (p<0.05) in hypertensive subjects (4.19±2.95) μIU/L when compared with the control (2.67±1.71) μIU/L. There was no significant difference when the serum level of FT3 and FT4 were compared between hypertensive and normotensive pregnant women (p>0.05). Subclinical hypothyroidism was found in 16.66% of hypertensive subjects. Conclusions: HDP is associated with thyroid hormone abnormalities. An increase in TSH levels with normal FT3 and FT4 levels were found to be the most common form of thyroid dysfunction during pregnancy.

Hypertensive disorders of pregnancy are one of the leading causes of fetal and maternal mortality worldwide. Aside from the immediate risk they pose for the pregnant woman, there is significant evidence that women after such a pregnancy have a long-term risk for the development of cardiovascular diseases. On the other hand, Galectin-3 is a biomarker that has proven its role in cardiac remodeling, fibrosis, and heart failure. To determine the levels of Galectin-3 in women with gestational hypertension, preeclampsia, and in healthy pregnant women and test for association with premature birth. A prospective single-center clinical, epidemiological study was performed, and data were analyzed for 123 pregnant women-36 with gestational hypertension, 37 with preeclampsia, and 50 controls. ELISA method was used to determine the serum levels of Galectin-3. Mean Galectin-3 level was 6,53 ng/ml in the controls, 7.30 ng/ml in the gestational hypertension group, and 7,59 ng/ml in the preeclampsia group. There was a significant difference in the levels between the controls and each of the pathological groups (P<0,05), while the two pathological groups were not statistically different from each other. Additionally, higher Galectin-3 levels were associated with an OR~2.5 for even preterm birth after adjustment for the presence of the two hypertensive disorders of pregnancy. Gestational hypertension and preeclampsia were associated with significantly higher levels of Galectin-3, which could be indicative of cardiovascular dysfunction in those women, and were also related to premature birth.

Abstract Background This study aims to explore whether plasma endocrine gland-derived vascular endothelial growth factor (EG-VEGF) in the first trimester can be used as a predictor of hypertensive disorders of pregnancy (HDP), and compare it with placental growth factor (PlGF) and soluble fms-like tyrosine kinase-1 (sFlt-1) to evaluate its prediction of HDP value. Methods This is a prospective cohort study that records the medical history of the pregnant women included in the study at 11–13 weeks’ gestation, and analyzes serum biochemical markers including EG-VEGF, PIGF, sFlt-1 and sFlt-1/PIGF. The predictive values of these tests were determined. We used the receiver operating characteristic (ROC) curve to find the optimal cut-off value for each biomarker and compare the operating characteristics (sensitivity, specificity). Logistic regression analysis was used to create a prediction model for HDP based on maternal characteristics and maternal biochemistry. Results Data were obtained from 205 pregnant women. 17 cases were diagnosed with HDP, the incidence rate was 8.2% (17/205). Women who developed HDP had a significantly higher body mass index (BMI) and mean arterial pressure (MAP). Serum EG-VEGF levels in the first trimester are significantly higher in pregnant women with HDP. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value(NPV) of serum EG-VEGF levels more than 227.83 pg/ml for predicting HDP were 43%, 93%, 86% and 62%, respectively. We established a prediction model in the first trimester include maternal BMI, MAP, and EG-VEGF, with an AUC of 0.8861 (95%CI: 0.7905–0.9818), which is better than using EG-VEGF alone (AUC: 0.66). Conclusion This study demonstrated that serum EG-VEGF is a promising biomarker for predicting HDP in the first trimester. It has better predictive performance compared with the currently used biomarkers like PIGF and sFlt-1. Combining maternal clinical characteristics and biochemical tests at 11–13 weeks can effectively identify women at high risk of HDP.

Background: Cardiovascular functions and hemodynamics dramatically change during pregnancy such as cardiac output, expanded blood volume, reduced systematic vascular resistance, and heart chamber enlargement. Hypertensive disorders of pregnancy (HDP) may affect the cardiac load during pregnancy; however, the data about plasma concentration of cardiac troponin in pregnant women with HDP is very limited. Methods: We prospectively collected data of 751 pregnant women between 2012 and 2013 in Japanese general hospital. We analyzed laboratory data and echocardiographic findings after delivery. The elevated cTnI was defined as >0.015 ng/mL because the normal population have serum cTnI of less than 0.015 ng/mL in this assay. Results: The HDP were observed in 32 patients; the elevated cTnI was observed 40 patients. The age of patients with HDP (33.7 ±4.3 years) was not different from that of those without HDP (33.3 ± 5.0 years). The brain natriuretic peptides levels were not different between those with and without HDP. The proportion of elevated cTnI was higher in those with HDP (21.8%) than those without (3.6%, P<0.0001). After adjusting for confounders, the risk of elevated cTnI in those with HDP relative to those without HDP remained significant (odds ratio 4.52, 95% confidence interval 1.45-14.5). There were no women with reduced left ventricular ejection fraction. Conclusions: HDP was associated with elevated cTni, suggesting myocardial microinjury might occur more frequently in those with HDP.

Purpose of the Review: The main objective of this study is to investigate mechanisms associated with gestational diabetes mellitus (GDM) and hypertensive disorders of pregnancy (HDP) in HIV infected pregnant women by looking how placental hormones such as (progesterone and prolactin) and basic haemostatic parameters are regulated in HIV infected pregnancies.Recent Findings: HIV/AIDS are a major global obstetric health burden that lead to increased rate of morbidity and mortality. HIV/AIDS has been associated with the pathophysiology of GDM and HDP. Increased risk of GDM due to highly active antiretroviral therapy (HAART) usage has been reported in HIV infected pregnancies, which causes insulin resistance in both pregnant and non-pregnant individuals. HAART is a medication used for lowering maternal antepartum viral load and pre-exposure and post-exposure prophylaxis of the infant. In pregnant women, HAART induces diabetogenic effect by causing dysregulation of placental hormones such as (progesterone and prolactin) and predispose HIV infected women to GDM. In addition to HIV/AIDS and GDM, Studies have indicated that HIV infection causes haemostatic abnormalities such as hematological disorder, deregulated haematopoiesis process and the coagulation process which results in HDP.Summary: This study will help on improving therapeutic management and understanding of the pathophysiology of GDM and HDP in the absence as well as in the presence of HIV infection by reviewing studies reporting on these mechanism.

Abstract The elucidation of dynamic metabolomic changes during gestation is particularly important for the development of methods to evaluate pregnancy status or achieve earlier detection of pregnancy-related complications. Some studies have constructed models to evaluate pregnancy status and predict gestational age using omics data from blood biospecimens; however, less invasive methods are desired. Here we propose a model to predict gestational age, using urinary metabolite information. In our prospective cohort study, we collected 2,741 urine samples from 187 healthy pregnant women, 23 patients with hypertensive disorders of pregnancy, and 14 patients with spontaneous preterm birth. Using gas chromatography-tandem mass spectrometry, we identified 184 urinary metabolites that showed dynamic systematic changes in healthy pregnant women according to gestational age. A model to predict gestational age during normal pregnancy progression was constructed; the correlation coefficient between actual and predicted weeks of gestation was 0.86. The predicted gestational ages of cases with hypertensive disorders of pregnancy exhibited significant progression, compared with actual gestational ages. This is the first study to predict gestational age in normal and complicated pregnancies by using urinary metabolite information. Minimally invasive urinary metabolomics might facilitate changes in the prediction of gestational age in various clinical settings.

Hypertensive disorders are the most common medical complications of pregnancy and a major cause of maternal and perinatal morbidity and death. The detection of elevated blood pressure during pregnancy is one of the cardinal aspects of optimal antenatal care. With the outbreak of novel coronavirus disease 2019 (COVID-19) and the risk for person-to-person spread of the virus, there is a desire to minimize unnecessary visits to health care facilities. Women should be classified as low risk or high risk for hypertensive disorders of pregnancy and adjustments can be accordingly made in the frequency of maternal and fetal surveillance. During this pandemic, all pregnant women should be encouraged to obtain a sphygmomanometer. Patients monitored for hypertension as an outpatient should receive written instructions on the important signs and symptoms of disease progression and provided contact information to report the development of any concern for change in status. As the clinical management of gestational hypertension and preeclampsia is the same, assessment of urinary protein is unnecessary in the management once a diagnosis of a hypertensive disorder of pregnancy is made. Pregnant women with suspected hypertensive disorders of pregnancy and signs and symptoms associated with the severe end of the disease spectrum (e.g., headaches, visual symptoms, epigastric pain, and pulmonary edema) should have an evaluation including complete blood count, serum creatinine level, and liver transaminases (aspartate aminotransferase and alanine aminotransferase). Further, if there is any evidence of disease progression or if acute severe hypertension develops, prompt hospitalization is suggested. Current guidelines from the American College of Obstetricians and Gynecologists (ACOG) and The Society for Maternal-Fetal Medicine (SMFM) for management of preeclampsia with severe features suggest delivery after 34 0/7 weeks of gestation. With the outbreak of COVID-19, however, adjustments to this algorithm should be considered including delivery by 30 0/7 weeks of gestation in the setting of preeclampsia with severe features.

Abstract Background Hypertensive disorders of pregnancy complicate around 6% of pregnancies and accounts for 19% of maternal death in Ethiopia. The current review aimed to assess maternal and perinatal outcomes of pregnancies complicated by hypertension in Ethiopia. Methods A systematic review and meta-analysis was done on the outcome of hypertensive disorder among pregnant women in Ethiopia. Literature search was made in five databases and Statistical analyses were carried out by using Stata 14 software. The pooled prevalence of maternal death, HELLP syndrome, perinatal death, and low birth weight was calculated using a random-effects model. Egger’s test and funnel plot were used to evaluate publication bias. The Cochran Q test and I2 test statistics were used to test the heterogeneity of studies. Result Thirteen studies included in the review, with an overall sample size of 5894 women diagnosed to have hypertensive disorder of pregnancy. The pooled prevalence of maternal death was estimated to be 4% (95% CI: 2, 6%). The pooled prevalence of HELLP syndrome was 13% (95% CI: 10, 16%). Other complications such as pulmonary edema, kidney injury, hepatic injury, placental abruption, and aspiration pneumonia were also reported. Perinatal death was observed in one-fourth of women with HDP 25% (95% CI: 18, 32%). The pooled prevalence of low birth weight neonate in a woman with HDP is 37% (95% CI, 27, 48%). Conclusions In Ethiopia, the prevalence of perinatal and maternal mortality among pregnant women with one of the hypertensive disorders were found to be higher than rates reported from high income as well as most of the low and middle income countries. For instance, one in four of pregnancies complicated by hypertensive disorder end up in perinatal death in Ethiopia. HELLP syndrome, placental abruption, pulmonary edema, renal damage, prematurity, perinatal asphyxia, and low birth weight were also commonly reported. To improve the health outcomes of hypertensive disorders of pregnancy, it is recommended to improve utilization of maternal health service; early detection and early referral of pregnant women with hypertensive disorder; advocating policies and strategies that improves the quality of health care that a pregnant woman and her newborn receive.
