[PMID: 38762675 PMCID: PMC11102370 DOI: 10.1007/s11306-024-02123-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 04/30/2024] [Indexed: 05/20/2024]
Abstract
INTRODUCTION Preeclampsia (PreE) remains a major source of maternal and newborn complications. Prenatal prediction of these complications could significantly improve pregnancy management. OBJECTIVES Using metabolomic analysis we investigated the prenatal prediction of maternal and newborn complications in early and late PreE and investigated the pathogenesis of such complications. METHODS Serum samples from 76 cases of PreE (36 early-onset and 40 late-onset), and 40 unaffected controls were collected. Direct Injection Liquid Chromatography-Mass Spectrometry combined with Nuclear Magnetic Resonance (NMR) spectroscopy was performed. Logistic regression analysis was used to generate models for prediction of adverse maternal and neonatal outcomes in patients with PreE. Metabolite set enrichment analysis (MSEA) was used to identify the most dysregulated metabolites and pathways in PreE. RESULTS Forty-three metabolites were significantly altered (p < 0.05) in PreE cases with maternal complications and 162 metabolites were altered in PreE cases with newborn adverse outcomes. The top metabolite prediction model achieved an area under the receiver operating characteristic curve (AUC) = 0.806 (0.660-0.952) for predicting adverse maternal outcomes in early-onset PreE, while the AUC for late-onset PreE was 0.843 (0.712-0.974). For the prediction of adverse newborn outcomes, regression models achieved an AUC = 0.828 (0.674-0.982) in early-onset PreE and 0.911 (0.828-0.994) in late-onset PreE. Profound alterations of lipid metabolism were associated with adverse outcomes. CONCLUSION Prenatal metabolomic markers achieved robust prediction, superior to conventional markers for the prediction of adverse maternal and newborn outcomes in patients with PreE. We report for the first-time the prediction and metabolomic basis of adverse maternal and newborn outcomes in patients with PreE.

Prenatal hypertension as the risk of eclampsia, HELLP syndrome, and critical obstetric hemorrhage. Hypertens Res 2024; 47:455-466. [PMID: 37993593 PMCID: PMC10838768 DOI: 10.1038/s41440-023-01511-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/29/2023] [Revised: 09/28/2023] [Accepted: 10/20/2023] [Indexed: 11/24/2023]
Abstract
Critical bleeding is a common cause of maternal mortality in obstetric patients. However, the non-obstetric factors underlying critical obstetric bleeding remain uncertain. Therefore, this study aimed to clarify the impact of chronic hypertension on obstetric hemorrhage by evaluating a nationwide administrative database in Japan. Women who gave birth between 2018 and 2022 were enrolled. The primary outcome was critical hemorrhage requiring massive red blood cell (RBC) transfusion during childbirth. In total, 354, 299 eligible women were selected from the database. The maternal mortality rate was >1.0% among those who received a massive RBC transfusion (≥4000 cc), and this amount was used as the cutoff of the outcome. Critical hemorrhage was less frequent with elective Caesarean section (CS) compared with vaginal childbirth or emergent CS (odds ratio [OR], 0.38; 95% confidence interval, 0.30-0.47). Multiple logistic regression analysis adjusting for these obstetric risks revealed that a higher maternal age (adjusted OR [aOR] per 1 year, 1.07 [1.05-1.09]); oral medications with prednisolone (aOR, 2.5 [1.4-4.4]), anti-coagulants (aOR, 10 [5.4-19]), and anti-platelets (aOR, 2.9 [1.3-6.4]); and a prenatal history of hypertension (aOR, 2.5 [1.5-4.4]) and hypoproteinemia (aOR, 5.8 [1.7-20]) are the risks underlying critical obstetric hemorrhage. Prenatal history of hypertension was significantly associated with obstetric disseminated intravascular coagulation (OR, 1.9 [1.5-2.4]); Hemolysis, Elevated Liver enzymes, and Low platelet count (HELLP) syndrome (OR, 3.3 [2.7-4.2]); and eclampsia (OR, 6.1 [4.6-8.1]). In conclusion, a maternal prenatal history of hypertension is associated with the development of HELLP syndrome, eclampsia, and resultant critical hemorrhage. The incidence of HELLP syndrome and eclampsia increased more than fivefold in the presence of prenatal hypertension. However, the likelihood of subsequently developing DIC or experiencing critical bleeding did not change by the presence of prenatal hypertension.

Abstract
Early pregnancy is a complex and well-orchestrated differentiation process that involves all the cellular elements of the fetal-maternal interface. Aberrant trophoblast-decidual interactions can lead to miscarriage and disorders that occur later in pregnancy, including preeclampsia, intrauterine fetal growth restriction, and preterm labor. A great deal of research on the regulation of implantation and placentation has been performed in a wide range of species. However, there is significant species variation regarding trophoblast differentiation as well as decidual-specific gene expression and regulation. Most of the relevant information has been obtained from studies using mouse models. A comprehensive understanding of the physiology and pathology of human implantation and placentation has only recently been obtained because of emerging advanced technologies. With the derivation of human trophoblast stem cells, 3D-organoid cultures, and single-cell analyses of differentiated cells, cell type-specific transcript profiles and functions were generated, and each exhibited a unique signature. Additionally, through integrative transcriptomic information, researchers can uncover the cellular dysfunction of embryonic and placental cells in peri-implantation embryos and the early pathological placenta. In fact, the clinical utility of fetal-maternal cellular trafficking has been applied for the noninvasive prenatal diagnosis of aneuploidies and the prediction of pregnancy complications. Furthermore, recent studies have proposed a viable path toward the development of therapeutic strategies targeting placenta-enriched molecules for placental dysfunction and diseases.

Abstract
PURPOSE OF REVIEW Hypertensive disorders of pregnancy remain a highly morbid condition that affects both the mother and fetus, complicate approximately 10% of pregnancies worldwide, and contribute to immediate and long-term cardiovascular outcomes. There is still much to learn regarding pathogenesis and treatment goals. RECENT FINDINGS There is updated information on the pathogenesis of preeclampsia and treatment thresholds for HTN in pregnancy. l-Kynurenine, a metabolite of the essential amino acid l-tryptophan, has been implicated in preeclampsia as decreased levels were found in a uninephrectomized pregnant mouse model of preeclampsia, where replacement of l-kynurenine rescued the preeclamptic state. Further, data from CHIPS (The Control of HTN in Pregnancy Study) and CHAP (Chronic HTN and Pregnancy) trials demonstrate not only the safety of lowering blood pressure to either a diastolic goal of 85 mmHg (CHIPS) or less than 160/105 mmHg (CHAP) without detriment to the fetus but the CHAPS trial has also shown a decrease in the rate of preeclampsia in the treatment group. SUMMARY We will summarize the different types of hypertensive disorders in pregnancy, updates on the pathogenesis of preeclampsia, and appropriate HTN management based on the latest evidence in order to better care for mother and child.

Abstract
Preeclampsia is characterized by maternal hypertension and multi-organ injury. Elongation factor Tu GTP binding domain containing 2 (EFTUD 2) and the Pregnancy Zone Protein (PZP) seem to be important immunomodulatory factors in early gestation. Little is known about the role of EFTUD2 and PZP in disorders of late pregnancy like preeclampsia, HELLP syndrome and intrauterine growth restriction (IUGR). PZP, EFTUD2 and hCG expression was investigated by immunohistochemistry in the placenta of healthy pregnancies (n = 13), preeclampsia (n = 11), HELLP syndrome (n = 12) and IUGR (n = 8). Correlation analysis of protein expression was performed via Spearman correlation coefficient. The characterization of EFTUD2 and PZP expressing cells was evaluated by double-immunofluorescence. After cultivation of the chorion carcinoma cell line BeWo with hCG the expression of PZP and EFTUD2 was investigated by immunocytochemistry. PZP expression was significantly downregulated in the syncytiotrophoblast (ST) and extravillous trophoblast (EVT) of preeclampsia (ST: p 0.001, EVT:p = 0.019) and HELLP syndrome (ST: p = 0.004, EVT: p = 0.035). The expression of EFTUD2 was significantly lower in preeclampsia (ST: p = 0.003, EVT: p 0.001), HELLP syndrome (ST: p = 0.021, EVT: = 0.001, EVT: p = 0.001). EVTs were identified as EFTUD2 and PZP expressing cells by double-immunofluorescence. Stimulation of BeWo chorion carcinoma cells with hCG 1000 IU/mL for 48 h resulted in a significant upregulation of PZP expression (p = 0.027). Our results indicate that PZP and EFTUD2 might be involved in the development of placental dysfunction in preeclampsia and HELLP syndrome.

Abstract
INTRODUCTION Preeclampsia is associated with adverse maternal and neonatal outcomes. It is unclear whether multivitamin use reduces the risk of preeclampsia. This systematic review and meta-analysis aimed to evaluate the association between multivitamin use and the risk of preeclampsia. MATERIAL AND METHODS We searched PubMed, Embase and the Cochrane Library from database inception to July 2021. Randomized controlled trials (RCTs), case-control and cohort studies assessing the association between multivitamin use and risk of preeclampsia were eligible. Studies of treatment with a single micronutrient were excluded. Relative risks and 95% confidence intervals (95% CI) were calculated using random-effects models. RoB2, the Newcastle Ottawa Scale and GRADE were used to assess risk of bias and quality of evidence. The protocol was registered in PROSPERO (no. CRD42021214153). RESULTS Six studies were included (33 356 women). Only two RCTs were found, both showing a significantly decreased risk of preeclampsia in multivitamin users. These studies were not compatible for meta-analysis due to clinical heterogeneity. A meta-analysis of observational studies using a random-effects model showed an unchanged risk of preeclampsia following multivitamin use (relative risk 0.85, 95% CI 0.69-1.03). The quality of evidence according to GRADE was very low. CONCLUSIONS Very weak evidence suggests that multivitamin use might reduce the risk of preeclampsia; however, more research is needed. Large RCTs should be prioritized. The results of this review do not allow any final conclusions to be drawn regarding a preventive effect of multivitamin use in relation to preeclampsia.

Abstract
Eclampsia is a common complication of preeclampsia patients and can be life-threatening for both the mother and the fetus. Hence, timely intervention and appropriate management of this detrimental condition are extremely crucial. Eclampsia is described as the occurrence of generalized convulsions in patients with preeclampsia. Magnesium sulfate (MgSO4) is the drug of choice for treating and preventing eclampsia. This review aims to study and analyze the available literature on the pathogenesis of eclampsia, the pharmacology of MgSO4, and its effectiveness in the management of eclampsia. Other proposed treatments and their comparative study with MgSO4 are also discussed. Additionally, we examine the data regarding the impact of eclampsia, its public health burden, and the cost-effectiveness of MgSO4. One of the major drawbacks associated with the use of MgSO4 in low-income countries has been the cost of treatment and the lack of resources. We have analyzed the trials that have proposed alternate treatment regimens which could shape new guidelines to resolve these issues. For this review, we extensively studied abstract and full-text articles from multiple databases. This article discusses the pathophysiology of eclampsia, the pharmacology of MgSO4, the issues surrounding eclampsia management, and how MgSO4 benefits these patients.

Abstract
Preeclampsia is a multifactorial condition associated with significant morbidity and mortality. Fluid therapy in these patients is challenging since volume expansion may precipitate pulmonary edema, and fluid restriction may worsen renal function. Furthermore, cardiac impairment may introduce an additional component to the hemodynamic management. This article reviews the repercussions of preeclampsia on renal and cardiovascular systems and the development of pulmonary edema, as well as to discuss fluid management, focusing on the mitigation of adverse outcomes and monitoring alternatives. The literature review was carried out using PubMed, Embase, and Google Scholar databases from May 2019 to March 2020. Papers addressing the subjects of interest were included regardless of the publication language. There is a current trend towards restricting the administration of fluids in women with non-complicated preeclampsia. However, patients with preeclampsia may experience hemorrhagic shock, requiring volume resuscitation. In this case, hemodynamic monitoring is recommended to guide fluid therapy while avoiding complications.

Abstract
Hypertensive disorders are a leading cause of maternal morbidity and mortality worldwide. Despite advances in prevention and clinical management, women in low-resource countries continue to bear the burden of the sequelae of severe pre-eclampsia-eclampsia. Sustainable strategies to improve the care of women with hypertensive disease, to identify those at risk for hypertensive disease, and to reduce the risk of eclampsia will require partnerships between clinicians and health policy makers. Resources are needed to scale up healthcare access and infrastructure, establish evidence-based protocols for care, and ensure an adequate supply of equipment and drugs. Additionally, efforts for a sustained workforce of perinatal clinicians and staff trained in the assessment and management of hypertensive disease are needed. Effective postpartum care and monitoring are essential to prevent morbidity and mortality due to cardiovascular disease. Culturally appropriate strategies are needed to educate women and their families on the symptoms of pre-eclampsia to address delays in seeking care during pregnancy and postpartum. With targeted, sustained efforts and resources, eclampsia and its associated co-morbidities can be preventable.

Abstract
Purpose Pre-eclampsia (PE) is a serious complication of pregnancy characterized by high blood pressure, proteinuria, compromised fetal blood supply, and potential organ damage. The superficial location of the eye makes it an ideal target for characterization hemodynamics. Our aim was to discern the impact of PE on ocular blood flow. Methods 18 MHz plane-wave ophthalmic ultrasound scanning was performed on subjects with PE (n = 26), chronic or gestational hypertension (n = 8), and normal controls (n = 19) within 72 hours of delivery. Duplicate three-second long scans of the posterior pole including the optic nerve were acquired at 6000 images/sec for evaluation of the central retinal artery and vein and the short posterior ciliary arteries. The choroid was scanned at 1000 images/sec. Doppler analysis provided values of pulsatile flow velocity and resistance indexes. Results End diastolic velocity was higher, and pulsatility and resistive indexes were significantly lower in the choroid, central retinal artery and short posterior ciliary arteries in PE than in controls. Blood pressure was elevated in PE with respect to controls and was negatively correlated with resistance. Conclusions Although vasoconstriction is considered characteristic of PE, we found reduced resistance in the orbital vessels and choroidal arterioles, implying vasodilation at this level. Future studies incorporating optical coherence tomography angiography for characterization of the retina and choriocapillaris in conjunction with plane-wave ultrasound scanning, particularly in late pregnancy, might address this conundrum. Translational Relevance Use of plane-wave ultrasound scanning for evaluation ocular blood flow in women at risk for PE may offer an avenue towards early detection and clinical intervention.

Abstract
Background Pre-eclampsia (PE) can be divided into 2 sub-groups: early-onset and late-onset PE. Although these sub-groups show overlapping molecular and cellular mechanisms and similar clinical manifestations, they are regarded as 2 different phenotypes with heterogeneous manifestations. The pathophysiological mechanisms underlying early-onset and late-onset PE still remain unclear. Therefore, the present study aimed to identify the key genes and pathways related to early-onset and late-onset PE, and to investigate the molecular mechanisms that are involved in gene regulation. Material/Methods Our analysis involved the Gene Expression Series (GSE) 74341 and GSE22526 from the National Center of Biotechnology Information (NCBI) Gene Expression Omnibus Database. These 2 microarray datasets included 15 patients with early-onset PE and 15 patients with late-onset PE. Results Our analyses identified 15 differentially expressed genes (DEGs), including CGA, EGR1, HBB, HBA2, LEP, and LHB. Gene Ontology (GO) functional annotation showed that the biological functions of these DEGs were mainly associated with steroid biosynthetic, oxidative stress, angiogenesis, and sex differentiation. Signaling pathway analyses showed that these DEGs were mainly involved in the prolactin signaling pathway, hormone metabolism, the AMPK signaling pathway, and the FoxO signaling pathway. Protein-protein interaction (PPI) network analysis identified 4 genes with the highest degree of interaction. The hub genes for this selection of DEGS were EGR1, LEP, and HBB. Conclusions Integrated bioinformatic analyses provide us with a new approach to further understand the pathophysiology and molecular mechanisms underlying early-onset and late-onset PE. The DEGs identified in this study represent potential biomarkers for the early diagnosis of PE and may provide significant options the treatment of these 2 subtypes of PE.

Abstract
BACKGROUND Magnesium sulfate is the ideal drug for the prevention and treatment of eclampsia. Nevertheless, the best regimen for protection against eclampsia with minimal side effects remains to be established. This study aimed to compare serum magnesium levels during intravenous infusion of magnesium sulfate at 1 gram/hour versus 2 grams/hour as a maintenance dose to prevent eclampsia in pregnant and postpartum women with severe preeclampsia. METHODS A randomized, triple-blind clinical trial was conducted, comparing serum magnesium levels during the intravenous infusion of magnesium sulfate at 1 gram/hour versus 2 grams/hour as a maintenance dose for the prevention of eclampsia in 62 pregnant and postpartum women with severe preeclampsia, 31 in each group. An intravenous loading dose of 6 grams of magnesium sulfate was administered over 30 minutes in both groups. The patients were then randomized to receive a maintenance dose of either 1 or 2 grams/hour for 24 hours. Primary outcomes consisted of serum magnesium levels at the following time points: baseline, 30 minutes, every 2 hours until the end of the first 6 hours, and every 6 hours thereafter until the termination of magnesium sulfate infusion. Side effects, maternal complications, and neonatal outcomes were the secondary outcomes. RESULTS Serum magnesium levels were higher in the 2-gram/hour group, with a statistically significant difference from 2 hours after the beginning of the magnesium sulfate infusion (P <.05). Oliguria was the most common complication recorded in both groups, with no significant difference between the 2 regimens (RR 0.88; 95% CI: 0.49-1.56; P = .65). No cases of eclampsia occurred. Side effects were more common in the 2-gram/hour group (RR 1.89; 95% CI: 1.04-3.41; P = .02); however, all were mild. There were no differences between the 2 groups regarding neonatal outcomes, except for admission to neonatal intensive care, which was more frequent in the 1-gram/hour group (25% vs 6.3%; P = .04). CONCLUSION Magnesium sulfate therapy at the maintenance dose of 1 gram/hour was just as effective as the 2-gram maintenance dose, with fewer side effects.

Peripheral Anti-Angiogenic Imbalance during Pregnancy Impairs Myogenic Tone and Increases Cerebral Edema in a Rodent Model of HELLP Syndrome. Brain Sci 2018; 8:brainsci8120216. [PMID: 30563221 PMCID: PMC6316026 DOI: 10.3390/brainsci8120216] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2018] [Revised: 12/04/2018] [Accepted: 12/04/2018] [Indexed: 01/14/2023] Open
Abstract
Using an animal model of hemolysis elevated liver enzymes low platelets (HELLP) that has systemic inflammation and neuroinflammation we wanted to determine if blood brain barrier (BBB) permeability, cerebral edema, vascular tone, and occludin expression were altered in pregnant rats. Anti-angiogenic proteins sFlt-1 and sEng (4.7 and 7 µg/kg/day, respectively) were chronically infused into normal pregnant (NP) rats beginning on gestational day 12 via a mini-osmotic pump. On gestational day 19, blood pressure was measured via a carotid catheter and brains were collected. BBB permeability was assessed in select brain regions from rats infused with 0.5 mg/mL Texas Red Dextran and phenylephrine. Occludin, sFlt-1, and sEng were analyzed via western blot or ELISA. Infusion of sFlt-1 and sEng into NP rats increased hemolysis and liver enzymes, and decreased platelets and led to hypertension. HELLP rats had significant impairment in the myogenic response and increased BBB permeability in the posterior cortex and brainstem. Brain water content in the posterior cortex was increased and sEng protein expression in the brainstem was significantly increased in HELLP rats. The results from this study suggest that a peripheral anti-angiogenic imbalance during pregnancy is associated with decreased myogenic tone, vasogenic edema, and an increase in BBB permeability, but not anti-angiogenic imbalance in the brain.

Abstract
BACKGROUND Hepatic rupture is a complication during pregnancy that, although rare, accounts for high morbidity and mortality rates. It is mainly associated with severe preeclampsia and HELLP syndrome. Incidence is estimated to be at one per 67,000 births or one per 2000 patients with preeclampsia/eclampsia/HELLP, mainly in multiparous women; women in their 40s; after 32 weeks of gestation; and during the first 15 h postpartum. CASES This article exposes the institutional experience at Fundación Valle del Lili in Cali, Colombia, in managing and treating hepatic rupture associated with severe preeclampsia and HELLP syndrome in three patients in the 30th, the 26th, and the 27th week of gestation, not resulting in maternal death. DISCUSSION A search in Pubmed, Embase, and Ovid from 2000 to 2017 resulted in 35 cases reported in either pregnant or puerperal women. Hepatic rupture is a rare complication in pregnancy associated with preeclampsia and HELLP syndrome. Its pathophysiology is attributed to the presence of vasospasm due to an increase in concentration and sensitivity to circulating vasopressors during pregnancy. There is no standard management, but surgery reduces mortality significantly. It includes endovascular management, partial hepatectomy, or transplant (only one patient required a liver transplant in our search). The most used techniques have been ligation of the hepatic artery, embolization of the hepatic artery, and examination, packing, and drainage of hepatic lesion for bleeding control (27 cases were treated with laparotomy with evacuation of hematoma and hemostasis and four cases were treated with embolization of the hepatic artery). Hepatic artery occlusion both by surgery ligation and by embolization through interventional radiology has reported successful and failing results during pregnancy Conclusion: Management of pathologies as hepatic rupture associated with severe preeclampsia and HELLP syndrome has to be clearly protocolized for prompt diagnosis and early management. Furthermore, it has to be carried out through multidisciplinary teams in high-complexity obstetrics scenarios.

Abstract
Introduction: Eclampsia is one of the most dreaded causes of adverse outcomes of pregnancy worldwide. It is one of the greatest causes of maternal and perinatal morbidity and mortality world over. We do not know the prevalence, management outcome, and the devastation caused by this dreaded disease in our center hence the need for this work. Materials and Methods: This is a 7-year retrospective review of all cases of eclampsia managed in Mater Misericordiae Hospital Afikpo, a rural secondary cum referral Catholic Mission Hospital in Afikpo, Ebonyi State in Southeastern Nigeria. Results: The prevalence of eclampsia in our center is 1.12% or one case of eclampsia for every 89 women that delivered in our facility. The majority of the women that had eclampsia in our center 56 (71.8%) were primigravidae. Seventeen women (21.8%) had various antenatal complications with 4 or 23.6% presenting with intrauterine fetal deaths and two (11.8%) each with intrauterine growth restriction, and domestic violence, respectively. Thirty-five or 44.9% of the women were delivered by emergency lower segment cesarean section. Fifteen or 17.9% babies were dead giving a perinatal mortality rate of 174 per 1,000After delivery, and 3 (3.8%) of the women had postpartum hemorrhage. Two women (2.6%) died giving a maternal mortality ratio of 2564 per 100,000 deliveries. Conclusion: Eclampsia is a dreaded obstetric disease with adverse fetal and maternal consequences that are not mitigating, and no effort should be spared in managing it effectively including public enlightenment.

Abstract
Spontaneous hepatic rupture is a rare complication of preeclampsia and HELLP syndrome. It carries a high maternal and perinatal mortality. Multidisciplinary management is key to optimal outcomes. Usual management includes perihepatic packing or angioembolization but formal lobectomy may be required in special cases.
Introduction Spontaneous hepatic rupture associated with preecalmpsia or HELLP syndrome is a rare and life threatining event, only 200 cases have been reported in the literature. Presentation of case We present a case of a 31 year old female with 28 weeks of gestation that presented with acute abdominal pain, elevated blood pressure and altered liver enzymes an abdominal ultrasound that showed a subcapsular hematoma occupying the whole right lobe and free abdominal fluid, she required emergent laparotomy, C-section, hepatic packing, followed by angioembolization and finally right hepatectomy. Discussion and conslusion Spontaneous hepatic rupture due to preeclampsia or HELLP syndrome is a medical emergency, it requires a prompt and decisive treatment. Multiple treatment modalities are available, from simple hepatic packing to endovascular embolization, but in extreme situations a formal hepatectomy might be required.

Abstract
Objective To characterise the current clinical practice patterns regarding the use of magnesium sulphate (MgSO4) for eclampsia prevention and treatment in a multi‐country network of health facilities and compare with international recommendations. Design Cross‐sectional survey. Setting A total of 147 health facilities in 15 countries across Africa, Latin America and Asia. Population Heads of obstetric departments or maternity units. Methods Anonymous online and paper‐based survey conducted in 2015. Main outcome measures Availability and use of MgSO4; availability of a formal clinical protocol for MgSO4 administration; and MgSO4 dosing regimens for eclampsia prevention and treatment. Results Magnesium sulphate and a formal protocol for its administration were reported to be always available in 87.4% and 86.4% of all facilities, respectively. MgSO4 was used for the treatment of mild pre‐eclampsia, severe pre‐eclampsia and eclampsia in 24.3%, 93.5% and 96.4% of all facilities, respectively. Regarding the treatment of severe pre‐eclampsia, 26.4% and 7.0% of all facilities reported using dosing regimens that were consistent with Zuspan and Pritchard regimens, respectively. Across regions, intramuscular maintenance regimens were more commonly used in the African region (45.7%) than in the Latin American (3.0%) and Asian (22.9%) regions, whereas intravenous maintenance regimens were more often used in the Latin American (94.0%) and Asian (60.0%) regions than in the African region (21.7%). Similar patterns were found for the treatment of eclampsia across regions. Conclusions The reported clinical use of MgSO4 for eclampsia prevention and treatment varied widely, and was largely inconsistent with current international recommendations. Tweetable abstract MgSO4 regimens for eclampsia prevention and treatment in many hospitals are inconsistent with international recommendations. MgSO4 regimens for eclampsia prevention and treatment in many hospitals are inconsistent with international recommendations.

Abstract
Retinal detachment is a rare, but well-known cause of visual impairment in patients with hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome. With supportive care, patients usually improve, with complete recovery of vision. Bedside ultrasonography of the orbit can be helpful for early detection of retinal detachment in these patients. Here, we present a case of HELLP syndrome presenting with severe visual symptoms. Retinal detachment was detected with point-of-care ocular sonography, which was confirmed with ophthalmoscopic examination. The patient was reassured of the favorable prognosis. Early initiation of aggressive supportive care was followed by progressive improvement of vision, which correlated with sonographic evidence of resolution of detachment. Her vision recovered completely in 2 weeks.

Abstract
Background There is a large body of literature which assessed the incidence and risk factors of eclampsia, but little was done in assessing the association of clinical features and biological markers with prepartum and postpartum eclampsia. Methods A total of 361 eclamptic women admitted to three teaching hospitals between 2008 and 2013 were included in this analysis. A comparative analysis was done for several clinical and biological variables to assess their association with prepartum and postpartum eclampsia. Results The overall incidence of eclampsia was 1.2% (prepartum 71% and postpartum 29%). The majority of women with prepartum eclampsia were young, primigravida, more hypertensive, symptomatic and proteinuric. Conversely, the majoritys of the women with post-partum eclampsia were adult, multiparous, carrying pregnancy to term, anemic, thrombocytopenic, and with hepatic dysfunction. The commonest severity symptom (headache) was less common in postpartum eclamptic women. Conclusion The incidence of eclampsia was among the highest in the world. And, the analysis has shown that the clinical and biochemical spectrum of prepartum and postpartum eclampsia were apparently different. The majority of the women who developed postpartum eclampsia were multiparous and adult. Derangement of biomarkers was also more common in women with postpartum eclampsia.

Abstract
Preeclampsia (PE) is a complex, hypertensive disorder of pregnancy, demonstrating considerable variability in maternal symptoms and fetal outcomes. Unfortunately, prior research has not accounted for this variability, resulting in a lack of robust biomarkers and effective treatments for PE. Here, we created a large (N=330) clinically relevant human placental microarray data set, consisting of 7 previously published studies and 157 highly annotated new samples from a single BioBank. Applying unsupervised clustering to this combined data set identified 3 clinically significant probable etiologies of PE: "maternal", with healthy placentas and term deliveries; "canonical", exhibiting expected clinical, ontological, and histopathologic features of PE; and "immunologic" with severe fetal growth restriction and evidence of maternal antifetal rejection. Moreover, these groups could be distinguished using a small quantitative polymerase chain reaction panel and demonstrated varying influence of maternal factors on PE development. An additional subclass of PE placentas was also revealed to form because of chromosomal abnormalities in these samples, supported by array-based comparative genomic hybridization analysis. Overall, our findings represent a new paradigm in our understanding of the origins and maternal-placental contributions to the pathology of PE. The study of PE represents a unique opportunity to access human tissue associated with a complex hypertensive disorder, and our novel approach could be applied to other hypertensive and heterogeneous human diseases.

Abstract
Hypertensive disorders complicate 5%-10% of pregnancies with increasing incidence mainly due to upward trends in obesity globally. In the last century, several terminologies have been introduced to describe the spectrum of this disease. The current and widely used classification of hypertensive pregnancy disorders was introduced in 1972 and in 1982, but has not been free of controversy and confusion. Unlike other diseases, the existing terminology combines signs and symptoms, but does not describe the underlying pathology of the disease itself. In this commentary, a detailed account is given to vascular disorder of pregnancy (VDP) as an inclusive terminology taking into account the underlying pathology of the disease on affected organs and systems. A simple and uniform classification scheme for VDP is proposed.

Abstract
Thrombotic microangiopathy (TMA) is a life-threatening condition that affects some, but not all, recipients of vascular endothelial growth factor (VEGF) inhibitors given as part of chemotherapy. TMA is also a complication of preeclampsia, a disease characterized by excess production of the VEGF-scavenging soluble VEGF receptor 1 (soluble fms-like tyrosine kinase 1; sFlt-1). Risk factors for VEGF inhibitor-related TMA remain unknown. We hypothesized that deficiency of the VWF-cleaving ADAMTS13 endopeptidase contributes to the development of VEGF inhibitor-related TMA. ADAMTS13(-/-) mice overexpressing sFlt-1 presented all hallmarks of TMA, including thrombocytopenia, schistocytosis, anemia, and VWF-positive microthrombi in multiple organs. Similar to VEGF inhibitor-related TMA in humans, these mice exhibited severely impaired kidney function and hypertension. In contrast, wild-type mice overexpressing sFlt-1 developed modest hypertension but no other features of TMA. Recombinant ADAMTS13 therapy ameliorated all symptoms of TMA in ADAMTS13(-/-) mice overexpressing sFlt-1 and normalized BP in wild-type mice. ADAMTS13 activity may thus be a critical determinant for the development of TMA secondary to VEGF inhibition. Administration of recombinant ADAMTS13 may serve as a therapeutic approach to treat or prevent thrombotic complications of VEGF inhibition.

Abstract
Background Preeclampsia (PE) is a life-threatening hypertensive pathology of pregnancy affecting 3–5% of all pregnancies. To date, PE has no cure, early detection markers, or effective treatments short of the removal of what is thought to be the causative organ, the placenta, which may necessitate a preterm delivery. Additionally, numerous small placental microarray studies attempting to identify “PE-specific” genes have yielded inconsistent results. We therefore hypothesize that preeclampsia is a multifactorial disease encompassing several pathology subclasses, and that large cohort placental gene expression analysis will reveal these groups. Results To address our hypothesis, we utilized known bioinformatic methods to aggregate 7 microarray data sets across multiple platforms in order to generate a large data set of 173 patient samples, including 77 with preeclampsia. Unsupervised clustering of these patient samples revealed three distinct molecular subclasses of PE. This included a “canonical” PE subclass demonstrating elevated expression of known PE markers and genes associated with poor oxygenation and increased secretion, as well as two other subclasses potentially representing a poor maternal response to pregnancy and an immunological presentation of preeclampsia. Conclusion Our analysis sheds new light on the heterogeneity of PE patients, and offers up additional avenues for future investigation. Hopefully, our subclassification of preeclampsia based on molecular diversity will finally lead to the development of robust diagnostics and patient-based treatments for this disorder.

Abstract
OBJECTIVE To describe the maternal outcome among women with eclampsia with and without HELLP syndrome (hemolysis, elevated liver enzymes, and low platelet count). METHODS A cross-sectional study of women with eclampsia was undertaken in 14 maternity units in Latin America between January 1 and December 31, 2012. Outcomes were compared between women with and without concomitant HELLP syndrome. Logistic regression analysis was performed to identify independent risk factors of maternal mortality. RESULTS There were 196 eclampsia cases among 115 038 deliveries; 142 (72.4%) women had eclampsia alone and 54 (27.6%) women had concomitant HELLP syndrome. Severe systolic hypertension (≥160 mm Hg), severe diastolic hypertension (≥110 mm Hg), and hypertensive encephalopathy were significantly more common among women with HELLP than among those with eclampsia alone (P=0.01 for all). There were 8 (4.1%) maternal deaths, all in the group with HELLP syndrome, and 18 (9.1%) perinatal deaths. In a multivariate regression model, maternal mortality was significantly associated with low platelet count and severe systolic hypertension (P<0.05). CONCLUSION Eclampsia with HELLP syndrome is a dangerous complication associated with pregnancy. Low platelet count secondary to HELLP syndrome and severe systolic hypertension were independently associated with maternal mortality from eclampsia.

Abstract
The aim of this study was to evaluate the morphometric and immunohistochemistry in umbilical cords from patients with severe pre-eclampsia with and without haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome. The patient and control groups were similar according to baseline obstetric characteristics. White blood cell count in patients with HELLP syndrome and the control group was significantly increased among patients with HELLP syndrome (p < 0.001). Morphometric examination and endothelial core length were significantly different between the groups. In the umbilical cord cross-section of the HELLP group, endothelial cell degeneration in the vessel wall and basement membrane thickening were observed. In the muscle layer of blood vessels, the following disorders were found: increased collagen fibres in the muscle cell, hyperplasia and separation of muscle fibres as well as edema in the intermediate connective tissue. Immunohistochemical analysis showed that endothelial cells, basal membrane and fibroblast cells in the HELLP group expressed high levels of CD44. Vessel wall and amniotic epithelial basement membrane thickening were observed in the HELLP group. Matrix metalloproteinase 9 (MMP9) was expressed. Fibroblast and smooth muscle cells were fusiform and showed a positive reaction to immunohistochemical staining of α-actin smooth muscle.

Abstract
A careful management of hepatic capsular rupture, with massive hemoperitoneum which occurred 14 hours after an emergency cesarean section at 36 weeks of gestation, is meticulously reported. The grade of hepatic involvement varies from minor capsular laceration to extensive parenchymal rupture. Our management involved a combination of surgical interventions and aggressive supportive care. The patient was discharged after 53 days and 4 laparotomies and an unsuccessful attempt of superselective artery embolization. Ultrasound after 40 days from the last surgery showed uniform hepatic parenchyma free of focal lesions. Due to the rarity and the unpredictability nature of this devastating event we believe necessary to report our experience, reinforcing the importance of the postsurgery management.

Abstract
BACKGROUND AND OBJECTIVE Preeclampsia is a multiple organ dysfunction syndrome (MODS) for its typical and atypical manifestations including hypertension, proteinuria, HELLP syndrome, hypertensive encephalopathy and coagulopathy. Optimal management for such patients is determined from an assessment of the balance between benefits and risks of anesthetic and obstetric therapeutic strategies. CASE REPORT A 35-year-old pregnant woman, with one past uncomplicated pregnancy presented at 29 weeks to our medical institute as an emergency with dizziness, chest distress, palpitation, blurred vision and vaginal bleeding. After physical examination and laboratory tests, the patient was diagnosed with severe preeclampsia, HELLP syndrome, placental abruption, and MODS. The patient also presented spinal and pelvic deformity, fixation of articulus mandibularis, and tracheal displacement because of a traffic accident 11 years ago. Therefore, urgent cesarean section was performed under general anesthesia with nasal tracheal intubation using a guide wire. The patient was discharged directly home from the obstetric intensive care unit on the 7(th) postoperative day with normal blood pressure and full recovery of organic function. CONCLUSIONS This case merits further discussion on the anesthesia considerations concerning how to make a clinical decision when treating such a patient. Neuraxial block is the first choice for preeclampsia patients undergoing cesarean section when a moderate but not progressive thrombocytopenia exists. When general anesthesia is decided, adequate sedation and analgesia is needed to better control the stress response to intubation especially in patients with neurological signs, and to prevent major cerebral complications.

Abstract
Background Preferred anticonvulsant used to treat and prevent fits in eclampsia currently is magnesium
sulphate. Clinical monitoring of tendon reflexes, respiration rate and measuring hourly urine output
should be done to ensures safe administration of magnesium sulphate Objective This study was conducted to evaluate maternal outcomes of magnesium sulphate and diazepam use in
the management of severe pre-eclampsia and eclampsia in Jimma University Specialized Hospital. Methods A retrospective hospital based cross-sectional comparative study was conducted using data
collection format. Data was collected from the hospital delivery care register and patient chart
records of all pregnant women who presented with the diagnosis of severe pre-eclampsia and eclampsia
in two years and three months period from January, 2010 to April, 2012. Data analysis was done by
SPSS version 16.0. A P-value of <0.05 was considered statistically significant in all
tests. Results A total of 357 patient charts, 217 from magnesium sulphate and 140 from diazepam treated pregnant
women group, were reviewed and analyzed. Three pregnant women from the magnesium sulphate treated
group and eleven pregnant women from diazepam treated group had at least one convulsion after taking
the drug. Greater proportion of patients in the magnesium sulphate treated group had less than four
days postpartum stay as compared to the diazepam treated patients (82.3% versus
66.2%). Seizure occurrence, duration of postpartum hospital stays and birth outcome had a
statistically significant association with the type of anticonvulsant used. Conclusions Magnesium sulphate is more effective than diazepam in the management of severe pre-eclamptic and
eclamptic pregnant women in terms of seizure prevention, shortening postpartum hospital stay and
reducing maternal morbidities.

An integrative review of the side effects related to the use of magnesium sulfate for pre-eclampsia and eclampsia management. BMC Pregnancy Childbirth 2013; 13:34. [PMID: 23383864 PMCID: PMC3570392 DOI: 10.1186/1471-2393-13-34] [Citation(s) in RCA: 44] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2012] [Accepted: 01/29/2013] [Indexed: 11/30/2022] Open
Abstract
Background Pre-eclampsia/eclampsia is one of the most common causes of maternal and perinatal morbidity and mortality in low and middle income countries. Magnesium sulfate is the drug of choice for prevention of seizures as part of comprehensive management of the disease. Despite the compelling evidence for the effectiveness of magnesium sulfate, concern has been expressed about its safety and potential for toxicity, particularly among providers in low- and middle-income countries. The purpose of this review was to determine whether the literature published in these global settings supports the concerns about the safety of use of magnesium sulfate. Methods An integrative review of the literature was conducted to document the known incidences of severe adverse reactions to magnesium sulphate, and specific outcomes of interest related to its use. All types of prospective clinical studies were included if magnesium sulfate was used to manage pre-eclampsia or eclampsia, the study was conducted in a low- or middle-income country, and the study included the recording of the incidence of any adverse side effect resulting from magnesium sulfate use. Results A total of 24 studies that compared a magnesium sulfate regimen against other drug regimens and examined side effects among 34 subject groups were included. The overall rate of absent patellar reflex among all 9556 aggregated women was 1.6%, with a range of 0-57%. The overall rate of respiratory depression in 25 subject groups in which this outcome was reported was 1.3%, with a range of 0–8.2%. Delay in repeat administration of magnesium sulfate occurred in 3.6% of cases, with a range of 0-65%. Calcium gluconate was administered at an overall rate of less than 0.2%. There was only one maternal death that was attributed by the study authors to the use of magnesium sulfate among the 9556 women in the 24 studies. Conclusion Concerns about safety and toxicity from the use of magnesium sulfate should be mitigated by findings from this integrative review, which indicates a low incidence of the most severe side effects, documented in studies that used a wide variety of standard and modified drug regimens. Adverse effects of concern to providers occur infrequently, and when they occurred, a delay of repeat administration was generally sufficient to mitigate the effect. Early screening and diagnosis of the disease, appropriate treatment with proven drugs, and reasonable vigilance for women under treatment should be adopted as global policy and practice.

Abstract
OBJECTIVE To review case reports of hepatic hematoma/rupture in women with pre-eclampsia/eclampsia. METHODS MEDLINE, SciELO, and LILACS databases were searched for case reports of pre-eclampsia/eclampsia with hepatic hematoma/rupture. Only articles written in English, Spanish, French, or Portuguese and published between 1990 and 2010 were reviewed. RESULTS In total, 180 cases of hepatic hematoma or rupture were identified: 18 (10.0%) with subcapsular hematoma without hepatic rupture; and 162 (90.0%) with capsule rupture. Twelve (6.7%) cases were associated with eclampsia plus hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome. Average age was 30.9 ± 5.0 years, 74/129 (57.4%) women were parous, and cesarean delivery was performed in 132/162 (81.5%) cases. The right lobule was the most frequently affected 77/100 (77.0%). The total maternal mortality rate was 22.2% during the 21 years; however, it decreased to 16.4% in the last decade studied. The perinatal mortality rate was 30.7% and was very similar during the 2 decades. CONCLUSION HELLP syndrome is a frequent diagnosis (92.8%) in hepatic hemorrhage/rupture. The major reduction in maternal mortality rate was probably associated with advances in resuscitation, intensive-care medicine, and surgical intervention, including liver transplantation and arterial embolization.

Abstract
OBJECTIVE To evaluate women with hypertensive disorder admitted to critical care unit. METHODS This study was carried out in Cartagena, Colombia, between January 2006 and December 2009. Patients were divided into 4 groups; severe pre-eclampsia, eclampsia, HELLP syndrome and HELLP with eclampsia (HEEH). RESULT A total of 217 cases were admitted. The admitting diagnoses were severe pre-eclampsia without HELLP syndrome (39.2%), HELLP syndrome without eclampsia (33.6%), eclampsia without HELLP syndrome (20.3%) and Eclampsia with HELLP syndrome or HEEH (6.9%). Groups were similar with respect to parity (p = 0.25), gestational age (p = 0.11), cesarean section (p = 0.58), mechanical ventilation (p = 0.54), level of systolic (p = 0.48) and diastolic blood pressure (p = 0.15) and inotropic support (p = 0.32). Average total duration of hospitalization was significantly different among groups, more time in women with HEEH (p = 0.001). Multiple organ dysfunctions was diagnosed > 70% of all women admitted to intensive care, but was significantly more frequent in patients with HELLP syndrome and HEEH (p = 0.001). There were 5 maternal deaths (2.3%). Causes of maternal death were intracranial hemorrhage (3), intra-abdominal bleeding (1) and pulmonary complications (1). CONCLUSION Women with HELLP syndrome with or without eclampsia are associated with major morbidity and mortality. Therefore, the maternal outcome in eclampsia is influenced for HELLP syndrome.

Abstract
OBJECTIVE To review case reports of retinal detachment in women with pre-eclampsia/eclampsia. METHODS Medline was searched for case reports of retinal detachment associated with pre-eclampsia/eclampsia. Articles written in English, Spanish, or Portuguese and published between 1990 and 2010 were reviewed. RESULTS A total of 28 cases of retinal detachment were identified; 15 were associated with severe pre-eclampsia (3 of these probably had hemolysis, elevated liver enzymes, and low platelets [HELLP] syndrome), 9 with HELLP syndrome, 2 with eclampsia, and 2 with both HELLP syndrome and eclampsia. The majority (60%) of women were nulliparous, 4 had abruptio placentae, and cesarean delivery was performed in 76%. Retinal detachment was bilateral in 89% and associated with delivery of the fetus in 96%; 69% were diagnosed postpartum. Within 2-12 weeks postpartum, all patients had complete recovery of vision with clinical management. CONCLUSION Retinal detachment in pre-eclampsia/eclampsia might be associated with HELLP syndrome, indicating that microangiophatic hemolysis might have a role in the pathophysiology of retinal detachment. Its occurrence might not be correlated with the severity of pre-eclampsia because pre-eclampsia is a constellation of signs and symptoms (persistent vasospasms with hemolysis and hypoalbuminemia) rather than simply being hypertension.

Abstract
Physiological alterations occur in many organ systems during pregnancy. These changes are necessary for the adaptation to pregnancy-specific physiological processes in mother and fetus, and the placenta plays a critical role in the maintenance of homeostasis in pregnancy. Dysregulation of these functional feto-maternal interactions leads to severe complications. There have been many attempts to create animal models that mimic the hypertensive disorders of pregnancy, especially pre-eclampsia. In this review, we summarize the physiology of pregnancy and placental function, and discuss the placental gene expression in normal pregnancy. In addition, we assess a number of established animal models focusing on a specific pathogenic mechanism of pre-eclampsia, including genetically modified mouse models involving the renin-angiotensin system. Validation of these animal models would contribute significantly to understanding the basic principles of pregnancy-associated homeostasis and the pathogenesis of pre-eclampsia.

Abstract
PURPOSE To evaluate the maternal and fetal outcome in 44 pregnancies complicated with HELLP syndrome and to investigate the role of platelet counts in its prognosis. METHODS A retrospective analysis of the medical records of 44 patients with the diagnosis of hemolysis elevated liver enzymes and low platelet count between June 1997 and January 2009 was performed. The patients were divided into two groups according to blood platelet count: platelet count <50,000 mm(3) formed Group I and platelet count 50,000-100,000 mm(3) formed Group II. Clinical findings and laboratory characteristics, maternal complications, perinatal outcomes and comparison of maternal and fetal morbidity according to platelet counts were analyzed. RESULTS During the period of 12 years, 44 (0.54%) of 8,132 deliveries had HELLP syndrome. Among 44 patients, the most common complications were disseminated intravascular coagulopathy (18.2%), acute renal failure (15.9%), abruptio placentae (11.4%), and cerebral hemorrhage/infarction (11.4%). Maternal and perinatal mortality rates in HELLP syndrome were 9.1 and 40.9%, respectively. Aspartate aminotransferase levels were found to be statistically significantly higher in Group I (p = 0.04). While disseminated intravascular coagulopathy and acute renal failure were statistically significantly higher in Group I (p = 0.01; p = 0.03 respectively), fetal growth restriction was statistically significantly higher in Group II (p = 0.04). CONCLUSIONS HELLP syndrome is associated with high incidences of maternal and fetal morbidity and mortality and patients with low platelet counts might have a much increased risk.
