Arterial Hypertension and Pregnancy about 72 Cases

Background: Hypertension is the leading cause of cardiovascular disease worldwide. Hypertensive disorders in pregnancy also constitute a major global health threat. There are different types of hypertension that can occur during pregnancy;with different mechanisms and consequences for mother and fetus. Objectives: To determine the frequency of hypertension (hypertension) during pregnancy. Document the risk factors for pregnancy-related hypertension. Review the material and fetal complications which determine the prognosis. Methods and Patients: This was a retrospective cross-sectional study from January 1 to June 30, 2022 in the Obstetrics and Gynecology Department of the Brazzaville Hospital and University Center. We noted 72 cases of hypertension among 1188 births admitted during the reference period. Hypertension was defined as blood pressure 40/90mmHg. Results: Hypertension was observed in 6% of those giving birth. The average age of the patients was 28 ± 8 years (range 15 to 39 years). The age group of 15 to 34 years was the most affected, 56 cases (778%). The risk factors were young age (15 - 34 years), late transfer of women in labor, 49 cases (68%). Primiparity, 33 cases (45.8%), absence of prenatal consultation, 7 cases (9.7%), hypertension, 8 cases (11%), twinning, 4 cases (5%), fetal macrosomia, one case (1.3%). Maternal complications recorded were: 21 cases of eclampsia (29%), 6 cases of left ventricular failure (8.3%), 5 cases of anemia (6.9%), 2 cases of retroplacental hematoma (2.8%), 1 case of HELLP syndrome, as much renal failure. Fetal and neonatal complications were 23 cases of prematurity (32%), 10 cases of acute fetal distress (14%), 4 cases of hypotrophy (5.6%). Eleven cases of death (15.3%) were: 3 in utero. B in the neonatal period.

Serum Magnesium Levels in Second and Third Trimesters of Pregnancy in Patients That Developed Pre-Eclampsia and Feto-Maternal Outcome

Introduction: Pregnancy is a physiological process that may be complicated by a number of clinical conditions. Gestational diabetes and pre-eclampsia are known complications in pregnancy. Pre-eclampsia is a disease of hypothesis in which the pathogenesis is yet to be fully explained. The role of magnesium in the pathogenesis of pre-eclampsia has been suggested by studies and it is being investigated all over the world. The study aimed to compare serum magnesium levels in pre-eclampsia and control groups from second trimester of pregnancy and assessed maternofetal outcome. Materials and Methods: This was a nested case control study in which consenting three hundred and sixty (360) normal pregnant women were enrolled. These women were recruited in their second trimester of pregnancy. Blood samples for serum magnesium estimation were obtained from subjects and controls at recruitment and after development of pre-eclampsia. Results: Thirty seven pregnant women that developed pre-eclampsia were nested as cases and were matched with 37 controls (apparently healthy pregnant women). The mean serum magnesium at recruitment was 0.75 ± 0.028 mmol/l (cases) and 0.76 ± 0.036 mmol/l (controls) (P = 0.123);this became significant when diagnosis of pre-eclampsia were made with mean of 0.53 ± 0.06 mmol/l (cases) and 0.69 ± 0.08 mmol/l (controls), (P 0.001). There was significant statistical relationship between preterm delivery, low birth weight and need for special care baby unit (SCBU) admission in newborn of mothers with low serum magnesium level (P = 0.001, 0.002 and 0.035 respectively). Conclusion: Findings from this study revealed that hypomagnesaemia appears to be a complication of pre-eclampsia. Serum levels of magnesium were normal until the development of the disease. Serum level of this biomarker affects maternofetal outcome significantly.

Pre-eclampsia with new-onset systemic lupus erythematosus during pregnancy: A case report

BACKGROUND New-onset systemic lupus erythematosus(SLE)during pregnancy and in the postpartum period is rare,especially when complicated with pre-eclampsia,which is difficult to diagnose accurately.Here,we report a patient with newonset SLE and antiphospholipid syndrome during pregnancy,which presented as pre-eclampsia at admission.CASE SUMMARY A 28-year-old primigravid woman was admitted to our hospital in the 27th wk of gestation with the primary diagnosis of severe pre-eclampsia.Although spasmolysis and antihypertensive therapy were administered since admission,the 24-h proteinuria of the 2nd day after admission reached 10311.0 mg.In the 47th h of admission,immunologic examinations revealed increased levels of antidouble stranded DNA antibody,anti-nuclear antibody,anti-cardiolipin antibody,anti-Sj?gren’s syndrome-related antigen A antibody and anti-nucleosome antibody and decreased levels of complement C3 and C4.One hour later,ultrasonography of the lower limbs showed thrombus of the bilateral popliteal veins.The diagnosis of SLE and antiphospholipid syndrome was indicated.In the 54th h,the patient manifested with convulsion,dyspnea and blurred vision.Ten hours later,intrauterine death was revealed by ultrasonography.Emergent surgery consisting of inferior vena cava filter implantation and subsequent cesarean section was performed.Following glucocorticoid and anticoagulation therapy after delivery,the patient had an optimal response with improvements in symptoms and immunological markers.CONCLUSION Obstetricians should be aware of the symptoms and immunological examination results to distinguish pre-eclampsia and underlying SLE for optimal pregnancy outcomes.

Association between Pre-pregnancy Body Mass Index and Offspring Neuropsychological Development from 1 to 24 Months of Age: A Birth Cohort Study in China

Objective To explore the interactions between pre-pregnancy body mass index(BMI) and age on offspring neuropsychological development from 1 to 24 months in China.Methods In this birth cohort study, a total of 2,253 mother-child pairs were enrolled in Tianjin, China,between July 2015 and May 2018. The China Developmental Scale for Children was used to assess developmental quotient(DQ) of children aged from 1 to 24 months.Results Mixed-models analysis revealed significant age × pre-pregnancy BMI interactions for total DQ and five neurobehavioral domains(gross motor, fine motor, adaptive, language, and social;P < 0.001).Age × pre-pregnancy BMI ≥ 25 kg/m^2 was associated with a negative effect on total DQ and five neurobehavioral domains, as compared to pre-pregnancy BMI < 25 kg/m^2(P < 0.01). Multiple comparisons showed pre-pregnancy BMI ≥ 25 kg/m^2 of mothers had a positive effect on child total DQ at the age of 1 month but a negative effect at 24 months(P < 0.05).Conclusions This study supported the age × pre-pregnancy BMI interaction on offspring neuropsychological development. It also revealed a short-term positive impact of high pre-pregnancy BMI on neuropsychological development at 1 month of age, but a long-term negative effect(from 1 to24 months).

Association between eNOS gene promoter polymorphism (-786T>C) and idiopathic recurrent pregnancy loss in Iranian women

Objective:To investigate the frequency of-786T>C variant in endothelial nitric oxide synthase(eNOS)gene promoter in Iranian women with recurrent pregnancy loss.Methods:Blood samples were obtained from 100 unrelated women affected by recurrent pregnancy loss and 100 unaffected women as the controls.Genomic DNA was extracted and-786T>C polymorphism in eNOS gene promoter was investigated by PCR-RFLP method.Statistical analyses and Hardy-Weinberg equilibrium in the groups of patients and controls were performed by Chi-square test and SPSS standard software(Version 21).Results:The frequency of homozygous TT was 40%in cases and 46%in the control group;the frequency of CC was 7%in cases and 5%in the control group;frequency heterozygote TC was 53%in cases and 49%in the control group.Genotype frequencies between the two groups showed no significant differences(P>0.05).Conclusions:The-786T>C polymorphism is not more frequent in recurrent pregnancy loss in this population.

Adverse pregnancy outcomes in women with high pre-pregnancy body mass index

Background/Aims: Obesity along with high prepregnancy body mass index (PP-BMI) is known to cause many adverse pregnancy outcomes. In Thailand, there is not much study showing both the prevalence and complications of these conditions. The objectives of this study were to estimate the prevalence of prepregnancy overweight and obesity and their impacts on adverse pregnancy outcomes. Methods: This study was a cross sectional study. Data were collected retrospectively from hospital electronic database along with manual retrieval from medical charts and labor records. Data of all delivery women from 1st February 2011 to 31st August 2012 were collected. When excluded cases with incomplete data and those without PP-BMI, 5420 cases were into analysis. Descriptive and inferential data analyses were used with both univariate and multivariate methods. Results: The proportion of pregnant women with overweight and obesity were 11.1% and 3.9%. After multiple logistic regression analysis was done, women in obesity group were correlated with having 1, 2 and 3 complications. They were also correlated with preeclampsia, gestational diabetes, cesarean section, higher birth weight group and long neonatal length. Conclusions: This Thai prevalence of obesity in pregnancyshould alarm health care providers to be more prepared, for a future health problem of the country. Many complications that come with obese pregnant women that were reported in western countries also happen in Thai population. Decreasing body weight before conception, giving correct health education, well planned pregnancy;antenatal lifestyle intervention and even gestational weight gain restricttion could help avoiding these uneventful morbidities.

Prevelance of Pregnancy Complications among Women Aged 15 - 49 in Oğuzeli, Turkey

As maternal deaths have decreased worldwide, increasing attention has been placed on the study of severe obstetric complications, such as hemorrhage, eclampsia, and obstructed labor, to identify where improvements can be made in maternal health. The objective of this study was to determine pregnancy complications and prenatal care among women aged 15 - 49 in O&#287;uzeli, Turkey, and to provide data for prevention in the field. This descriptive, cross-sectional study was conducted between February and May 2013 in O&#287;uzeli distinct, Turkey. The total women registered to family doctors in O&#287;uzeli was listed and, 470 women were selected using a stratified and simple random sampling technique. Pregnancy complications were asked for the last pregnancy of each women. Of the women, 23.9% (n = 109) declared that they experienced pregnancy complications during their pregnancies. The most frequent problems were anemia (11.1%) hypertension (3.7%) and diabetes mellitus (2.4%) respectively. Women having chronic diseases before their pregnancy were more likely to have pregnancy complications compared to healthy women (p = 0.005). The mean number of prenatal care among women having pregnancy complications was 5.47 ± 3.57, while it was 3.84 ± 3.00 among healthy women (p = 0.000). Women having chronic diseases should be handled carefully and, pregnancy should be delayed until the chronic disease’s remission. Family planning in primary care is the key measure to archive this. Early diagnosis of hypertension among young women is highly important for the women’s and infants’s health during pregnancy, and for the women’s future heath. During prenatal care, women should be trained about correct eating habits and activity.

Hot topics in lupus pregnancy

Systemic lupus erythematosus(SLE) typically affects women in their childbearing age, who have the same fertility rates as the healthy population. The effect of pregnancy on the disease and the effect of SLE on pregnancy and the fetus are highly important issues for the attending physician. Whether lupus flares are more frequent during pregnancy remains controversial. Among the possible effects of SLE on pregnancy are a greater number of abortions, fetal loss, pre-term deliveries and perinatal mortality. The newborn may be affected by the onset of neonatal lupus erythematosus(neonatal LE), either as a skin or blood disease, or by the presence of congenital heart block. The frequent association between SLE and antiphospholipid syndrome represents another risk situation for the mother and the product of conception. Multiples drugs used in SLE patients should be evaluated. Those with teratogenic potential should be withdrawn before pregnancy, and when necessary, appropriate medications should be indicated to treat the mother without compromising the safety of the baby. In conclusion, pregnancies in lupus patients represent a challenge for the physician and must be closely followed up and treated if necessary, during all trimesters and in the puerperium period, to improve outcome.

目的探讨妊娠合并慢性乙型肝炎患者乙肝标志物与HBV-DNA载量的相关性。方法选择收治的120例妊娠合并慢性乙型肝炎患者,采用酶联免疫吸附法检测乙肝五项(HBV-M)和乙肝前S1抗原(Pre-S1),采用荧光定量聚合酶链反应法(PCR)检测HBV-DNA,对结果行相关性分析。结果HBsAg、HBeAg、HBcAb阳性模式下HBV-DNA阳性率为80.49%,Pre-S1阳性率为75.61%,组间差异无统计学意义(P>0.05);HBsAg、HBeAb、HBcAb阳性模式下HBV-DNA阳性率为42.50%,Pre-S1阳性率为35.00%,组间差异无统计学意义(P>0.05);Pre-S1阳性检出率在HBsAg、HBsAb、HBeAg、HBeAb、HBcAb阳性和阴性标本中差异均有统计学意义(P<0.05)。经Pearson相关性分析,HBeAg、HBsAg与Pre-S1呈正相关关系;HBeAb与Pre-S1呈负相关关系;HBV-DNA与Pre-S1为正相关关系。结论妊娠合并慢性乙肝患者HBV-M、Pre-S1与HBV-DNA相关性高,对慢性乙肝的预测具有一定意义。
