Early diagnosis of preeclampsia is important to help patients with preeclampsia. However, 24-hour urine collection is the gold standard diagnostic method at present. Recently, the spot urinary protein-to-creatinine ratio (P/C ratio) has been used to detect suspected preeclampsia, because it can be used to estimate the amount of 24-hour urinary protein. The aim of this study is to investigate whether an increase in P/C ratio precedes emergence of hypertension among inpatients with preeclampsia. Method: The P/C ratio in normotensive (systolic blood pressure < 140 mm Hg and diastolic blood pressure < 90 mm Hg) pregnant women was measured during regular prenatal checkups and in inpatients with preeclampsia between April 1, 2013 and March 31, 2014. Results: We included in this study 4074 normotensive pregnant women. The 95th percentile values for the trimester of pregnancy were 0.100, 0.157, and 0.195, respectively. The 95th percentile value for each trimester of pregnancy and gestational age were determined as criterion (Y) and predictive variables (X), respectively. In a simple regression analysis, the regression line was calculated as Y = 0.0035X + 0.0849 (R2 = 0.9913). Twenty-one women were diagnosed with preeclampsia. In 14 patients with preeclampsia, the timing of the increase in P/C ratio to higher than the regression line preceded the emergence of hypertension. Six patients had no data on P/C ratio, and 1 patient had hypertension before the increase in P/C ratio. Conclusions: An increase in P/C ratio to higher than the 95th percentile value can be a useful predictor of preeclampsia.展开更多

Metabotropic glutamate receptor 1 participates in the onset of lipid metabolism disorder-induced preeclampsia. Pregnant rats were fed with a high-fat diet for 20 days. Thus, these pregnant rats experienced preeclampsia-like syndromes such as hyper-tension and proteinuria. Simultaneously, metabotropic glutamate receptor 1 mRNA and protein ex-pressions were upregulated in the rat hippocampus. These findings indicate that increased expres-sion of metabotropic glutamate receptor 1 promotes the occurrence of high-fat diet-induced pree-clampsia in pregnant rats.展开更多

The spectrum ranges from mild preeclampsia with no systemic involvement to multi-system involvement. The course is unpredictable and delivery is the only curative treatment. Elevated blood pressure(> 160/110 mm Hg) should be reduced gradually to a safe level(140/90) using antihypertensive drugs. Prophylaxis and treatment of convulsions using Mg SO4 is indicated for severe preeclampsia. Fluid therapy is controversial due to potential delicate balance between constricted plasma volume and risk of fluid overload and pulmonary oedema secondary to increased capillary permeability and reduced colloid osmotic pressure. Single shot spinal anaesthesia is the technique of choice for caesarean delivery unless contraindicated. General anaesthesia is indicated in patients with coagulopathy or eclampsia but is associated with risk of difficult airway and exaggerated sympathetic response during laryngoscopy. Epidural analgesia and anaesthesia is safe in absence of coagulopathy.展开更多

Here we present an atypical case of severe preeclampsia complicated by generalized convulsions (eclampsia) and hemolysis, elevated liver enzymes, and low platelet count syndrome in an 18 weeks pregnant patient with chronic hypertension. Occurrence of these complications was preceded by upper right quadrant abdominal pain and severe hypertension. In this case no evidence of autoimmunity disorders or molar pregnancy was found.展开更多

Objective: To determine if administering loading dose of MgSo4 on pregnant women with severe preeclampsia and eclampsia at primary care level would improve maternal and fetal outcomes. Method: Two sets of Primary Health Care (PHC) facilities were identified;one served as experimental one and the other as control. The community health extension workers (CHEWs) and the community health officers (CHOs) at the experimental PHCs were trained to administer the loading dose of MgSo4 for patients with SPE/E, in addition to other supportive treatments, before making a referral while the control PHCs did not give MgSo4, and neither administered diazepam as an alternative or no anti-convulsant at all, before making a referral to higher centers. Patients from the experimental and control facilities were prospectively monitored for fetal and maternal outcomes, namely maternal and fetal deaths, and for toxic effects of MgSo4 in the experimental arm. Results: Of the 150 patients recruited, 82 (55%) were in the experimental group and 68 (45%) were in the control group. 90% of the patients in the experimental group defaulted after receiving the loading dose of MgSo4 while the remaining 10% completed the referral process. 44% of those in the control group completed the referral process. There were 3 maternal and 3 perinatal deaths, all in the control group. No adverse outcome (maternal or fetal death) or toxic effect was recorded among the recipients of MgSo4. Conclusion: This study suggests that lower-cadre health care professionals at PHCs can administer the loading dose of MgSo4 to SPE/E patients to improve maternal and fetal survival in critical states, without significant risk of adverse effects. However, the lack of compliance with referral processes remains a huge challenge.展开更多

The objective of this study was to analyze and evaluate the available medications and techniques for the prevention and treatment of pre-eclampsia and eclampsia. The standard methodology of systematic review without meta-analysis was followed and only RCTs and systematic reviews were included in the review. Three electronic data sources (PubMed/Medline, CINAHL, and Cochrane) were searched for studies, published between 1986 and 2016 on the prevention and control of pre-eclampsia and eclampsia. 47 studies were finally included in the review, of which 18 were systematic reviews and 29 were RCTs. Technologies and techniques used in the included studies for the prevention and control of pre-eclampsia and eclampsia are Magnesium Sulphate, Aspirin, Antioxidant (Vitamin C, E and Lycopene), Calcium supplementation, Chinese Herbal Medicine, physical activities, Nitric Oxide, Marine Food Oils, Low Salt Diet, Garlic, Plasma Volume Expansion, Low-dose Dopamine, Progesterone, Smoking, and Diuretics. Magnesium sulfate appears to be the most effective treatment which reduces the risk of eclampsia by more than 50%. However, its best dose and route are still controversial and need further research. The knowledge and experience of nurses in properly using the protocols and evidence-based interventions are necessary for the wellbeing of pregnant women.展开更多

It is responsible for high maternal and perinatal morbidity and mortality. Accordingly, the objective of this work was to study the factors associated with the occurrence of maternal and perinatal complications of preeclampsia. Method: This was an analytical cross-sectional study with prospective and retrospective data collection including all patients, pregnant or postpartum, admitted for pre-eclampsia to the maternity ward of the Yaoundé Central Hospital. It took place over a period of seven (07) months. The data collected was analyzed using CS Pro 7.4, SPSS 20.0 and Microsoft Office Excel 2010 software. We compared the group with complications to the group without complications. We calculated the odds ratio to look for associations between variables and their 95% confidence intervals. The threshold for statistical significance was set at p Results: We recruited 214 cases of preeclampsia in our series. There were maternal complications in 44.4% of cases, dominated by eclampsia (31.8%). We recorded 07 maternal deaths, representing a maternal lethality of 3.3%. We had at least one perinatal complication in 105 cases (49.1%). The predominant perinatal complication was prematurity. We recorded 32 cases of intrauterine fetal demise and 13 cases of early neonatal death, giving a perinatal lethality of 21%. After logistic regression, the factors associated with maternal complications were residing in a rural area (OR = 2.217 [1.054 - 3.09];p < 0.036);a nurse-aid as prenatal consultation provider (PNC) (OR = 5.059 [2.175 - 36.162];p - 4.029]). Conclusion: Complications of preeclampsia are very common in our setting. Several identified factors are associated with the occurrence of these complications. We suggest building the capacity of providers of PNC and sensitization of women on the use of PNC services.展开更多

Good nursing management of pre-eclampsia could stabilize and limit possible maternal and fetal complication. Aim: This study aims to assess nurses’ knowledge of the management of pre-eclampsia. This is a descriptive prospective study conducted at the Van Norman Clinic over three-month period from November 1st, 2020 to January 31st, 2021 to assess the knowledge of nurses assigned to the Patient reception service, Emergency service, Gynecological-Obstetrics service and Community Medicine department on the management of pre-eclampsia. Data were treated using Microsoft Word and analyzed by Statistical Package for Social Scientists version 16 (SPSS). During the period of our study, we collected 40 nurses out of 44 nurses, which represents 90.9% (n = 40) of the nurses assigned to the Patient reception service, Emergency service, Gynecological-Obstetrics service and Community Medicine department. Among the 40 cases collected, 30% respondents did not give the true definition of pre-eclampsia. Our study also showed that 70% of nurses had not been trained on the management of pre-eclampsia and 90% had not used nursing theories in their practice while the Inquiry-Based Practice (IBP) and Evidence-Based Practice (EBP) applications were known in 7.5% of cases. With regard to the nursing management of pre-eclampsia, 62.5% of cases knew the first gestures of management while 90% of cases did not know the overall nursing management of pre-eclampsia. Last of continuing education, use of nursing theories and lack of resuscitation were the main obstacles observed in the nursing management of pre-eclampsia. For better nursing management of pre-eclampsia, emphasis should be placed on building staff capacity and executing the care plan by applying nursing theories.展开更多

In sub-Saharan Africa, Nigeria accounts for the highest maternal mortality ratio of 512 deaths per 100,000 live deliveries and the highest neonatal fatality of 67 per 1000 live births. Factors such young age, nulliparity, multifetal gestation, unbooked cases, preterm delivery (<32 weeks), lack of proper access to antenatal care, poor hospital care, financial constraints and inappropriate diagnosis, have all been identified as risk factors promoting eclampsia. Objectives: In this study, we investigated the prevalence of eclampsia in Rivers State, Nigeria and established the correlation between social demographic factors and the feto-maternal outcomes among the eclampsia patients. Methodology: A prospective observational study using a detailed data sheet was conducted on 1244 pregnant women admitted at the Obstetrics and Gynecology Department of University of Port Harcourt Teaching Hospital, for 1-year duration. Data analysis was conducted using statistical packages for social sciences (SPSS) version 22. Results: Demography showed that age range (20 - 24) occurred in 40.7%, nulliparous mothers were dominant with 40.7% while 70.1% of the study population had secondary level of education. 27 cases of eclampsia were diagnosed from the 1244 pregnant women, which signified 2.13% prevalence among the studied population. The feto-maternal outcome showed that out of the 27 mothers, 19 were alive (70.4%) while 8 died (29.6%), while fetal outcome showed that 16 were alive (59.3%) and 11 died (40.7%). Only parity and education showed significant correlation at 0.01 and 0.05 levels respectively with maternal outcome. Conclusion: The prevalence of eclampsia with associated poor feto-maternal outcome rates is high in this study. Its contribution to the maternal and perinatal morbidities and mortalities necessitates the narrative of eclampsia being a scourge, as hypertensive disease remains an obstetric dilemma in both developed and developing countries.展开更多

This study was a comparative cross-sectional study conducted in some selected hospitals in Kaduna State, between April 2014 and November 2015. Subjects and Methods: Blood (3 mls) was collected into an ethylenediaminetetraaccetic acid (EDTA) vacutainer tube from third trimester women diagnosed with eclampsia (EC;n = 38) and healthy pregnant controls (PC;n = 38)—age and parity matched and healthy non-pregnant controls (NPC;n = 38)—age matched. T Cell subpopulations and Complete Blood Count levels were measured by Sysmex, Auto blood analyzer and flow cytometry respectively. Participants with smear positive malaria, seropositive for human immunodeficiency virus (HIV), any other clinical infection or refused consent were excluded from this study. Data obtained were analyzed using analysis of variance (ANOVA) and Post Hoc test. A p-value of less than 0.05 was considered to be significant. Result: Overall, results showed a depressed (mean ± Standard deviation (SD): CD3+ T cell (65.6 ± 15.5%;1225.5 ± 401.5 cell/μL), CD4+ T cell (36.1 ± 8.7%;657.1 ± 189.9 cell/μL), and a low CD4/CD8 value in women with EC (1.4 ± 0.5) and PC (1.5 ± 0.3) compared to NPC (1.9 ± 0.6) control (p < 05), while the total white blood cell count, and differential percentage neutrophils count were noted to be elevated among the eclamptic women (9.8 ± 4.9 × 109/L;70.3 ± 12.0%) compared to PC (6.9 ± 3.6 × 109/L;64.6 ± 8.1%) and NPC (5.6 ± 2.0 × 109/L;48.5 ± 10.7%), p < 0.05. Conclusion: Eclampsia was associated with significantly depressed CD3+ and CD4+ T lymphocyte, and increased percentage differential neutrophil counts.展开更多

Objective: The objective of our study was to investigate the association between placental malaria lesions and severe pre-eclampsia. Methodology: We conducted a prospective analytical cross-sectional study in two University Hospitals in the city of Yaounde (Yaounde Central Hospital and the Gynaecological Obstetrics and Paediatrics Hospital), and in the laboratory of the Centre Pasteur in Yaounde over an eight-month period (1st January 2021 – 1st September 2021). All patients with pre-eclampsia diagnosed according to the criteria of the International Society for the Study of Hypertension (ISSHP) and free of chronic metabolic or infectious pathology were included in this study. The patients were divided into two groups: group 1 (mild pre-eclampsia) and group 2: severe pre-eclampsia. Socio-demographic, clinical and histopathological characteristics specific to pre-eclampsia and placental malaria were investigated. Statistical analysis was performed with SPSS 23.0 software, Chi 2 was used to compare categorical variables, Student t-test was used to compare means, and logistic regression was used to assess the association between placental malaria lesions and PES. Results: The mean age of our study population was 29.93 ± 7.36 years versus 28.28 ± 7.18 years in patients with mild and severe pre-eclampsia respectively. Pre-eclampsia placental lesions (accelerated villous maturation, infarction) were significantly greater in patients with severe pre-eclampsia (p Conclusion: Placental malaria lesions were significantly associated with severe pre-eclampsia and increased the risk of developing severe pre-eclampsia placental lesions by a factor of 10.展开更多

The NOSTR1N rnRNA in umbilical tissues was determined by RT-PCR. The eNOS activity in umbilical vessels was spectrophotometrically detected. NO2 /NO3, the stable metabolic end products of NO, was measured by using nitrate reductase. RT-PCR showed that the expression level of NOSTRIN was significantly higher in women with PE than in the normal group （P〈0.01）. The activity of eNOS was significantly decreased in PE group [（12.83±3.61） U/mg] than in normal group [（21.72±3.83） U/mg] （P〈0.01）. The level of NO2-/NO3- in PE patients （27.53±7.48） pmol/mg was significantly lower than that of normal group （54.27±9.53） μmol/mg （P〈0.01）. The significant negative correlation existed between the expression of NOSTRIN and the activity of eNOS in umbilical vessels of women with PE （r=-0.58, P〈0.01）. It was concluded that the level of NOSTR1N expression was increased in umbilical vessel of women with PE, indicating that it may be involved in the pathogenesis of PE.展开更多

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.展开更多

Methods: Doppler measurements were taken in fetal descending aorta and umbilical arteries of 53 patients with pre-eclampsia, 10 of whom had HELLP syndrome using fetometry (ACUSON 128XP/10, 3.5 MHz probe). These values were compared with those of 44 appropriate-for-gestational age singleton pregnancies (AGA). Doppler Indices (Resistance Index (RI), Systolic/Diastolic (S/D) ratio) and end-diastolic flows were related to fetal heart rate (FHR) during contraction stress test, to cord blood parameters (pH, Base Excess) and to Apgar Scores. Results: In contrast to AGA fetuses, IUGR fetuses had decreased end-diastolic flow and an increase of Doppler Indices significantly earlier in the descending aorta (p < 0.05), compared to umbilical artery. Increased RI’s, S/D ratios and a decrease of end-diastolic flow in fetal aorta were significantly correlated to frequency of FHR decelerations during contraction stress tests, pH, Base Excess (p < 0.01) and Apgar Scores in IUGR fetuses. Conclusion: A decrease in end-diastolic flow paralleled with an increase in Doppler indices in fetal descending aorta reflect oxygen deprivation in IUGR fetuses during pre-eclamptic pregnancies with or without HELLP syndrome. While ductus venosus and umbilical artery are more frequently used nowadays to determine fetal oxygen deprivation, Doppler measurements in fetal descending aorta provide additional information for early detection of fetuses at risk for IUGR in pregnancies complicated with pre-eclampsia and/or HELLP展开更多

Aim of the Work: To identify different factors predicting transformation of non-severe pre-eclampsia in to pre-eclampsia with severe features. Patients and Methods: This prospective cohort study was conducted at tertiary care hospital at Ain Shams University hospitals from June 2021 till January 2022 and performed on total of 100 patients who diagnosed as non-severe pre-eclampsia after exclusion of severity features. Results: The current study revealed that transformation to severe pre-eclampsia occurred in 33% of the studied cases. Body mass index (BMI), past and family histories of preeclampsia statistically were significantly higher in cases transformed into preeclampsia with severe features. Admission blood pressure, albumin dipstick, Oligohydramnios and IUGR statistically were significantly higher in cases with transformation from non-severe pre-eclampsia into pre-eclampsia with severe features. Platelet count statistically was significantly lower in cases with transformation from non-severe pre-eclampsia into pre-eclampsia with severe features Conclusion: Our study results identified the most important clinical risk factors for transformation to severe features of pre-eclampsia from non-severe features and provided new information on the level of risk associated with specific combinations of risk factors (BMI ≥ 35.4, admission systolic blood pressure, admission diastolic blood pressure, albumin dipstick 4+ and platelets count) with low significant diagnostic performance in predicting transformation from non-severe pre-eclampsia into pre-eclampsia with severe features.展开更多

The expression of neutrophil CD11b was significantly elevated in women with pre eclampsia as compared with that of normal pregnant women at third trimester. The mean fluorescence index of CD11b was 438.38±179.91 and 326.97±170.14 respectively ( P < 0.05). The plasma ET 1 level and serum NO 2 concentration in pre eclampsic women (63.69±48.33 pg/ml and 20.03±4.77 μmol/L, respectively) were both significantly increased as compared with those in the normal pregnancy women (29.98±20.25 pg/ml and 15.47±5.47 μmol/L, respectively, P <0.01). The neutrophil CD11b expression was significantly elevated in pre eclampsia. The increased neutrophil activation may cause the damage of vascular endothelium and result in NO release compensatory increase in endothelial cells, suggesting that the neutrophil activation may play a key role in pathogenesis of pre eclampsia.展开更多

文摘Objectives: Preeclampsia is a major cause of maternal and perinatal morbidity and mortality. Early diagnosis of preeclampsia is important to help patients with preeclampsia. However, 24-hour urine collection is the gold standard diagnostic method at present. Recently, the spot urinary protein-to-creatinine ratio (P/C ratio) has been used to detect suspected preeclampsia, because it can be used to estimate the amount of 24-hour urinary protein. The aim of this study is to investigate whether an increase in P/C ratio precedes emergence of hypertension among inpatients with preeclampsia. Method: The P/C ratio in normotensive (systolic blood pressure < 140 mm Hg and diastolic blood pressure < 90 mm Hg) pregnant women was measured during regular prenatal checkups and in inpatients with preeclampsia between April 1, 2013 and March 31, 2014. Results: We included in this study 4074 normotensive pregnant women. The 95th percentile values for the trimester of pregnancy were 0.100, 0.157, and 0.195, respectively. The 95th percentile value for each trimester of pregnancy and gestational age were determined as criterion (Y) and predictive variables (X), respectively. In a simple regression analysis, the regression line was calculated as Y = 0.0035X + 0.0849 (R2 = 0.9913). Twenty-one women were diagnosed with preeclampsia. In 14 patients with preeclampsia, the timing of the increase in P/C ratio to higher than the regression line preceded the emergence of hypertension. Six patients had no data on P/C ratio, and 1 patient had hypertension before the increase in P/C ratio. Conclusions: An increase in P/C ratio to higher than the 95th percentile value can be a useful predictor of preeclampsia.

文摘Changes in neurotransmitter levels in the brain play an important role in epilepsy-like attacks after pregnancy-induced preeclampsia-eclampsia. Metabotropic glutamate receptor 1 participates in the onset of lipid metabolism disorder-induced preeclampsia. Pregnant rats were fed with a high-fat diet for 20 days. Thus, these pregnant rats experienced preeclampsia-like syndromes such as hyper-tension and proteinuria. Simultaneously, metabotropic glutamate receptor 1 mRNA and protein ex-pressions were upregulated in the rat hippocampus. These findings indicate that increased expres-sion of metabotropic glutamate receptor 1 promotes the occurrence of high-fat diet-induced pree-clampsia in pregnant rats.
文摘Preeclampsia is a pregnancy specific syndrome of elusive etiology, developing in 2nd trimester and associated with high maternal and perinatal morbidity and mortality. The spectrum ranges from mild preeclampsia with no systemic involvement to multi-system involvement. The course is unpredictable and delivery is the only curative treatment. Elevated blood pressure(> 160/110 mm Hg) should be reduced gradually to a safe level(140/90) using antihypertensive drugs. Prophylaxis and treatment of convulsions using Mg SO4 is indicated for severe preeclampsia. Fluid therapy is controversial due to potential delicate balance between constricted plasma volume and risk of fluid overload and pulmonary oedema secondary to increased capillary permeability and reduced colloid osmotic pressure. Single shot spinal anaesthesia is the technique of choice for caesarean delivery unless contraindicated. General anaesthesia is indicated in patients with coagulopathy or eclampsia but is associated with risk of difficult airway and exaggerated sympathetic response during laryngoscopy. Epidural analgesia and anaesthesia is safe in absence of coagulopathy.
文摘Preeclampsia is a pregnancy specific disease characterized by hypertension and proteinuria, by definition, developing after 20 weeks of pregnancy. Here we present an atypical case of severe preeclampsia complicated by generalized convulsions (eclampsia) and hemolysis, elevated liver enzymes, and low platelet count syndrome in an 18 weeks pregnant patient with chronic hypertension. Occurrence of these complications was preceded by upper right quadrant abdominal pain and severe hypertension. In this case no evidence of autoimmunity disorders or molar pregnancy was found.
文摘Background: Evidence has shown that Magnesium Sulphate (MgSo4) is the gold standard for treating severe pre-eclampsia and eclampsia (SPE/E), and calls for its widespread use at all levels of health service delivery, including the primary care level. Objective: To determine if administering loading dose of MgSo4 on pregnant women with severe preeclampsia and eclampsia at primary care level would improve maternal and fetal outcomes. Method: Two sets of Primary Health Care (PHC) facilities were identified;one served as experimental one and the other as control. The community health extension workers (CHEWs) and the community health officers (CHOs) at the experimental PHCs were trained to administer the loading dose of MgSo4 for patients with SPE/E, in addition to other supportive treatments, before making a referral while the control PHCs did not give MgSo4, and neither administered diazepam as an alternative or no anti-convulsant at all, before making a referral to higher centers. Patients from the experimental and control facilities were prospectively monitored for fetal and maternal outcomes, namely maternal and fetal deaths, and for toxic effects of MgSo4 in the experimental arm. Results: Of the 150 patients recruited, 82 (55%) were in the experimental group and 68 (45%) were in the control group. 90% of the patients in the experimental group defaulted after receiving the loading dose of MgSo4 while the remaining 10% completed the referral process. 44% of those in the control group completed the referral process. There were 3 maternal and 3 perinatal deaths, all in the control group. No adverse outcome (maternal or fetal death) or toxic effect was recorded among the recipients of MgSo4. Conclusion: This study suggests that lower-cadre health care professionals at PHCs can administer the loading dose of MgSo4 to SPE/E patients to improve maternal and fetal survival in critical states, without significant risk of adverse effects. However, the lack of compliance with referral processes remains a huge challenge.
文摘Every pregnant woman needs continuous, timely and supportive care throughout during pregnancy for safe motherhood. The objective of this study was to analyze and evaluate the available medications and techniques for the prevention and treatment of pre-eclampsia and eclampsia. The standard methodology of systematic review without meta-analysis was followed and only RCTs and systematic reviews were included in the review. Three electronic data sources (PubMed/Medline, CINAHL, and Cochrane) were searched for studies, published between 1986 and 2016 on the prevention and control of pre-eclampsia and eclampsia. 47 studies were finally included in the review, of which 18 were systematic reviews and 29 were RCTs. Technologies and techniques used in the included studies for the prevention and control of pre-eclampsia and eclampsia are Magnesium Sulphate, Aspirin, Antioxidant (Vitamin C, E and Lycopene), Calcium supplementation, Chinese Herbal Medicine, physical activities, Nitric Oxide, Marine Food Oils, Low Salt Diet, Garlic, Plasma Volume Expansion, Low-dose Dopamine, Progesterone, Smoking, and Diuretics. Magnesium sulfate appears to be the most effective treatment which reduces the risk of eclampsia by more than 50%. However, its best dose and route are still controversial and need further research. The knowledge and experience of nurses in properly using the protocols and evidence-based interventions are necessary for the wellbeing of pregnant women.
文摘Introduction: Pre-eclampsia (PE) is a public health problem especially in developing countries due to its incidence and severity. It is responsible for high maternal and perinatal morbidity and mortality. Accordingly, the objective of this work was to study the factors associated with the occurrence of maternal and perinatal complications of preeclampsia. Method: This was an analytical cross-sectional study with prospective and retrospective data collection including all patients, pregnant or postpartum, admitted for pre-eclampsia to the maternity ward of the Yaoundé Central Hospital. It took place over a period of seven (07) months. The data collected was analyzed using CS Pro 7.4, SPSS 20.0 and Microsoft Office Excel 2010 software. We compared the group with complications to the group without complications. We calculated the odds ratio to look for associations between variables and their 95% confidence intervals. The threshold for statistical significance was set at p Results: We recruited 214 cases of preeclampsia in our series. There were maternal complications in 44.4% of cases, dominated by eclampsia (31.8%). We recorded 07 maternal deaths, representing a maternal lethality of 3.3%. We had at least one perinatal complication in 105 cases (49.1%). The predominant perinatal complication was prematurity. We recorded 32 cases of intrauterine fetal demise and 13 cases of early neonatal death, giving a perinatal lethality of 21%. After logistic regression, the factors associated with maternal complications were residing in a rural area (OR = 2.217 [1.054 - 3.09];p < 0.036);a nurse-aid as prenatal consultation provider (PNC) (OR = 5.059 [2.175 - 36.162];p - 4.029]). Conclusion: Complications of preeclampsia are very common in our setting. Several identified factors are associated with the occurrence of these complications. We suggest building the capacity of providers of PNC and sensitization of women on the use of PNC services.

文摘Background: Pre-eclampsia is one of the pathologies of pregnancy that causes serious maternal and fetal complications. Good nursing management of pre-eclampsia could stabilize and limit possible maternal and fetal complication. Aim: This study aims to assess nurses’ knowledge of the management of pre-eclampsia. This is a descriptive prospective study conducted at the Van Norman Clinic over three-month period from November 1st, 2020 to January 31st, 2021 to assess the knowledge of nurses assigned to the Patient reception service, Emergency service, Gynecological-Obstetrics service and Community Medicine department on the management of pre-eclampsia. Data were treated using Microsoft Word and analyzed by Statistical Package for Social Scientists version 16 (SPSS). During the period of our study, we collected 40 nurses out of 44 nurses, which represents 90.9% (n = 40) of the nurses assigned to the Patient reception service, Emergency service, Gynecological-Obstetrics service and Community Medicine department. Among the 40 cases collected, 30% respondents did not give the true definition of pre-eclampsia. Our study also showed that 70% of nurses had not been trained on the management of pre-eclampsia and 90% had not used nursing theories in their practice while the Inquiry-Based Practice (IBP) and Evidence-Based Practice (EBP) applications were known in 7.5% of cases. With regard to the nursing management of pre-eclampsia, 62.5% of cases knew the first gestures of management while 90% of cases did not know the overall nursing management of pre-eclampsia. Last of continuing education, use of nursing theories and lack of resuscitation were the main obstacles observed in the nursing management of pre-eclampsia. For better nursing management of pre-eclampsia, emphasis should be placed on building staff capacity and executing the care plan by applying nursing theories.
文摘Background: Eclampsia is responsible for over 50,000 maternal deaths with incidence of 1 death in about 100 - 1500 deliveries in developing nations. In sub-Saharan Africa, Nigeria accounts for the highest maternal mortality ratio of 512 deaths per 100,000 live deliveries and the highest neonatal fatality of 67 per 1000 live births. Factors such young age, nulliparity, multifetal gestation, unbooked cases, preterm delivery (<32 weeks), lack of proper access to antenatal care, poor hospital care, financial constraints and inappropriate diagnosis, have all been identified as risk factors promoting eclampsia. Objectives: In this study, we investigated the prevalence of eclampsia in Rivers State, Nigeria and established the correlation between social demographic factors and the feto-maternal outcomes among the eclampsia patients. Methodology: A prospective observational study using a detailed data sheet was conducted on 1244 pregnant women admitted at the Obstetrics and Gynecology Department of University of Port Harcourt Teaching Hospital, for 1-year duration. Data analysis was conducted using statistical packages for social sciences (SPSS) version 22. Results: Demography showed that age range (20 - 24) occurred in 40.7%, nulliparous mothers were dominant with 40.7% while 70.1% of the study population had secondary level of education. 27 cases of eclampsia were diagnosed from the 1244 pregnant women, which signified 2.13% prevalence among the studied population. The feto-maternal outcome showed that out of the 27 mothers, 19 were alive (70.4%) while 8 died (29.6%), while fetal outcome showed that 16 were alive (59.3%) and 11 died (40.7%). Only parity and education showed significant correlation at 0.01 and 0.05 levels respectively with maternal outcome. Conclusion: The prevalence of eclampsia with associated poor feto-maternal outcome rates is high in this study. Its contribution to the maternal and perinatal morbidities and mortalities necessitates the narrative of eclampsia being a scourge, as hypertensive disease remains an obstetric dilemma in both developed and developing countries.
文摘Background: Eclampsia, the occurrence of generalized convulsion(s) in association with signs of preeclampsia [PE] (hypertension and proteinuria) in pregnancy has remained a significant public threat in Nigeria, contributing to maternal and perinatal morbidity and mortality. This study was a comparative cross-sectional study conducted in some selected hospitals in Kaduna State, between April 2014 and November 2015. Subjects and Methods: Blood (3 mls) was collected into an ethylenediaminetetraaccetic acid (EDTA) vacutainer tube from third trimester women diagnosed with eclampsia (EC;n = 38) and healthy pregnant controls (PC;n = 38)—age and parity matched and healthy non-pregnant controls (NPC;n = 38)—age matched. T Cell subpopulations and Complete Blood Count levels were measured by Sysmex, Auto blood analyzer and flow cytometry respectively. Participants with smear positive malaria, seropositive for human immunodeficiency virus (HIV), any other clinical infection or refused consent were excluded from this study. Data obtained were analyzed using analysis of variance (ANOVA) and Post Hoc test. A p-value of less than 0.05 was considered to be significant. Result: Overall, results showed a depressed (mean ± Standard deviation (SD): CD3+ T cell (65.6 ± 15.5%;1225.5 ± 401.5 cell/μL), CD4+ T cell (36.1 ± 8.7%;657.1 ± 189.9 cell/μL), and a low CD4/CD8 value in women with EC (1.4 ± 0.5) and PC (1.5 ± 0.3) compared to NPC (1.9 ± 0.6) control (p < 05), while the total white blood cell count, and differential percentage neutrophils count were noted to be elevated among the eclamptic women (9.8 ± 4.9 × 109/L;70.3 ± 12.0%) compared to PC (6.9 ± 3.6 × 109/L;64.6 ± 8.1%) and NPC (5.6 ± 2.0 × 109/L;48.5 ± 10.7%), p < 0.05. Conclusion: Eclampsia was associated with significantly depressed CD3+ and CD4+ T lymphocyte, and increased percentage differential neutrophil counts.
文摘BACKGROUND Eclampsia is a generalized tonic-clonic seizure induced by pregnancy.It contributes to a high rate of maternal and neonatal morbidity and mortality worldwide.Eclampsia is characterised by classic signs such as elevated blood pressure,proteinuria,and seizures.However,it may occur in the absence of hypertension and/or proteinuria.The uncommon appearance of eclampsia makes it difficult to immediately assess and treat it.In addition,the occurrence of this case in a remote area makes it more challenging to handle.The objective of this case report is to increase awareness of uncommon manifestations of eclampsia,particularly in limited-resource settings.CASE SUMMARY A young primigravida experienced a generalised seizure without hypertension and/or proteinuria.Sudden hearing loss,blurred vision,and vomiting were complained about before the seizure attack.The patient was diagnosed with eclampsia.A loading dose of magnesium sulphate was administered immediately.The patient was referred from community healthcare to a hospital and discharged without any complications.CONCLUSION Atypical eclampsia may be a diagnostic challenge.However,other symptoms may be beneficial,such as awareness of eclampsia signs.
文摘Context: Pre-eclampsia and placental malaria, are two diseases that share pathophysiological similarities, such as placental ischemia, endothelial dysfunction and production of pro-inflammatory cytokines. Objective: The objective of our study was to investigate the association between placental malaria lesions and severe pre-eclampsia. Methodology: We conducted a prospective analytical cross-sectional study in two University Hospitals in the city of Yaounde (Yaounde Central Hospital and the Gynaecological Obstetrics and Paediatrics Hospital), and in the laboratory of the Centre Pasteur in Yaounde over an eight-month period (1st January 2021 – 1st September 2021). All patients with pre-eclampsia diagnosed according to the criteria of the International Society for the Study of Hypertension (ISSHP) and free of chronic metabolic or infectious pathology were included in this study. The patients were divided into two groups: group 1 (mild pre-eclampsia) and group 2: severe pre-eclampsia. Socio-demographic, clinical and histopathological characteristics specific to pre-eclampsia and placental malaria were investigated. Statistical analysis was performed with SPSS 23.0 software, Chi 2 was used to compare categorical variables, Student t-test was used to compare means, and logistic regression was used to assess the association between placental malaria lesions and PES. Results: The mean age of our study population was 29.93 ± 7.36 years versus 28.28 ± 7.18 years in patients with mild and severe pre-eclampsia respectively. Pre-eclampsia placental lesions (accelerated villous maturation, infarction) were significantly greater in patients with severe pre-eclampsia (p Conclusion: Placental malaria lesions were significantly associated with severe pre-eclampsia and increased the risk of developing severe pre-eclampsia placental lesions by a factor of 10.
文摘The expression of endothelial nitric oxide synthase traffic inducer （NOSTRIN） was examined in the umbilical vessels of the patients with pre-eclampsia （PE） to explore its possible role in the pathogenesis of PE. The NOSTR1N rnRNA in umbilical tissues was determined by RT-PCR. The eNOS activity in umbilical vessels was spectrophotometrically detected. NO2 /NO3, the stable metabolic end products of NO, was measured by using nitrate reductase. RT-PCR showed that the expression level of NOSTRIN was significantly higher in women with PE than in the normal group （P〈0.01）. The activity of eNOS was significantly decreased in PE group [（12.83±3.61） U/mg] than in normal group [（21.72±3.83） U/mg] （P〈0.01）. The level of NO2-/NO3- in PE patients （27.53±7.48） pmol/mg was significantly lower than that of normal group （54.27±9.53） μmol/mg （P〈0.01）. The significant negative correlation existed between the expression of NOSTRIN and the activity of eNOS in umbilical vessels of women with PE （r=-0.58, P〈0.01）. It was concluded that the level of NOSTR1N expression was increased in umbilical vessel of women with PE, indicating that it may be involved in the pathogenesis of PE.

文摘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.
文摘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.
文摘Objective: To determine diagnostic utility of Doppler measurements in fetal descending aorta and umbilical arteries in predicting intrauterine growth retarded (IUGR) fetuses at risk in pregnancies complicated by preeclampsia and/or HELLP syndrome. Methods: Doppler measurements were taken in fetal descending aorta and umbilical arteries of 53 patients with pre-eclampsia, 10 of whom had HELLP syndrome using fetometry (ACUSON 128XP/10, 3.5 MHz probe). These values were compared with those of 44 appropriate-for-gestational age singleton pregnancies (AGA). Doppler Indices (Resistance Index (RI), Systolic/Diastolic (S/D) ratio) and end-diastolic flows were related to fetal heart rate (FHR) during contraction stress test, to cord blood parameters (pH, Base Excess) and to Apgar Scores. Results: In contrast to AGA fetuses, IUGR fetuses had decreased end-diastolic flow and an increase of Doppler Indices significantly earlier in the descending aorta (p < 0.05), compared to umbilical artery. Increased RI’s, S/D ratios and a decrease of end-diastolic flow in fetal aorta were significantly correlated to frequency of FHR decelerations during contraction stress tests, pH, Base Excess (p < 0.01) and Apgar Scores in IUGR fetuses. Conclusion: A decrease in end-diastolic flow paralleled with an increase in Doppler indices in fetal descending aorta reflect oxygen deprivation in IUGR fetuses during pre-eclamptic pregnancies with or without HELLP syndrome. While ductus venosus and umbilical artery are more frequently used nowadays to determine fetal oxygen deprivation, Doppler measurements in fetal descending aorta provide additional information for early detection of fetuses at risk for IUGR in pregnancies complicated with pre-eclampsia and/or HELLP
文摘Background: Pre-eclampsia (PE), a complex, multisystem, pregnancy-associated hypertensive disorder, typically developing after the 20<sup>th</sup> week of gestation, that complicates 2% - 8% of pregnancies, is a leading cause of neonatal and maternal mortality and morbidity. Aim of the Work: To identify different factors predicting transformation of non-severe pre-eclampsia in to pre-eclampsia with severe features. Patients and Methods: This prospective cohort study was conducted at tertiary care hospital at Ain Shams University hospitals from June 2021 till January 2022 and performed on total of 100 patients who diagnosed as non-severe pre-eclampsia after exclusion of severity features. Results: The current study revealed that transformation to severe pre-eclampsia occurred in 33% of the studied cases. Body mass index (BMI), past and family histories of preeclampsia statistically were significantly higher in cases transformed into preeclampsia with severe features. Admission blood pressure, albumin dipstick, Oligohydramnios and IUGR statistically were significantly higher in cases with transformation from non-severe pre-eclampsia into pre-eclampsia with severe features. Platelet count statistically was significantly lower in cases with transformation from non-severe pre-eclampsia into pre-eclampsia with severe features Conclusion: Our study results identified the most important clinical risk factors for transformation to severe features of pre-eclampsia from non-severe features and provided new information on the level of risk associated with specific combinations of risk factors (BMI ≥ 35.4, admission systolic blood pressure, admission diastolic blood pressure, albumin dipstick 4+ and platelets count) with low significant diagnostic performance in predicting transformation from non-severe pre-eclampsia into pre-eclampsia with severe features.
文摘To investigate the effect of neutrophil activation on pathogenesis of pre eclampsia, neutrophil activation was examined by using flow cytometry to assess the CD11b expression and the levels of plasma endothelin 1 (ET 1) and serum NO - 2 were also measured by using non equilibrium radioimmunoassay and by Griess assay in 29 pregnant women with pre eclampsia and 31 normal pregnant women at third trimester. The expression of neutrophil CD11b was significantly elevated in women with pre eclampsia as compared with that of normal pregnant women at third trimester. The mean fluorescence index of CD11b was 438.38±179.91 and 326.97±170.14 respectively ( P < 0.05). The plasma ET 1 level and serum NO 2 concentration in pre eclampsic women (63.69±48.33 pg/ml and 20.03±4.77 μmol/L, respectively) were both significantly increased as compared with those in the normal pregnancy women (29.98±20.25 pg/ml and 15.47±5.47 μmol/L, respectively, P <0.01). The neutrophil CD11b expression was significantly elevated in pre eclampsia. The increased neutrophil activation may cause the damage of vascular endothelium and result in NO release compensatory increase in endothelial cells, suggesting that the neutrophil activation may play a key role in pathogenesis of pre eclampsia.
文摘Serous retinal detachment is a rare complication occurring in less than 1% of patients with eclampsia. We here report such a case. We strongly recommend the need for an eye check up in all patients of pregnancy induced hypertension especially in community based setup.
