Full Text Available El virus de Epstein-Barr (VEB es un agente patógeno común para los humanos y su efecto en la infección vertical es poco estudiado. Durante el embarazo hay riesgo a contraer infecciones que afectan al feto. La infección adquirida antes del nacimiento ocasiona abortos, mortinatos, malformaciones, retraso en el crecimiento intrauterino, prematuridad y secuelas por infección postnatal crónica. Los efectos inmediatos o a largo plazo representan un problema a nivel mundial. Durante el embarazo se ha mostrado una prevalencia del 98% y aproximadamente el 40% de las embarazadas son susceptibles y transmitirán el virus al feto. Los actuales exámenes clínicos de rutina revelan pocos hallazgos específicos en la madre pues en su mayoría la infección por VEB tiene un curso asintomático. La poca efectividad en su tratamiento hace que la prevención y el diagnóstico sean de gran importancia. Se conoce que el VEB se mantiene latente en el 90% de los pacientes después de la infección primaria y que la infección puede ser reactivada debido a diversos factores como el estrés crónico, posiblemente debido a la disminución de la respuesta inmune celular. En la presente investigación se evaluó la prevalencia de la infección por VEB en mujeres gestantes y con aborto que se encontraban durante las primeras 15 semanas de embarazo. Las muestras de pacientes de la consulta de obstetricia en diferentes ambulatorios de los Municipios Libertador y Campo Elías del Estado Mérida y de mujeres en la sala de emergencia obstétrica del Instituto Autónomo Hospital Universitario de Los Andes (IAHULA que acudieron por aborto durante las primeras semanas, se analizaron con una prueba ELISA para la detecctar anticuerpos séricos de tipo IgG VCA-VEB que no discriminan entre una primoinfección y una infección pasada. El 35% de la población de estudio fueron 9 mujeres en gestación sin antecedente de aborto y el 65% corresponde a 17 mujeres que historia previa

Full Text Available Objetivo: Describir las experiencias vividas por las mujeres con una gestación por preeclampsia severa en el Hospital de San José de la ciudad de Bogotá, Colombia. Método: Estudio cualitativo fenomenológico. Participaron diez mujeres puérperas que presentaron preeclampsia severa y fueron atendidas en el Hospital de San José durante el año 2012. Las participantes fueron seleccionaron mediante un muestreo intencional. El tamaño de la muestra se determinó por el criterio de saturación de la información. La información se recolectó mediante de una entrevista a profundidad y los datos se analizaron mediante la propuesta de Colaizzi. Resultados: La vivencia de la enfermedad dio cuenta de tres grandes categorías. Dos de ellas, la vivencia de la mujer, y con su hijo prematuro, emergieron como travesías que narraron el duro camino recorrido por el binomio madre-hijo desde su hospitalización hasta la recuperación de los dos en el hogar y los diferentes soportes con los que contó. Estas trayectorias estuvieron marcadas por sentimientos de miedo, angustia, incertidumbre; el sufrimiento por los síntomas físicos y el sometimiento a dolorosos procedimientos médicos. La tercera categoría dio cuenta de la falta de preparación de las participantes para enfrentarse a la enfermedad y todo lo que conllevaba. Conclusiones: Es necesario el fortalecimiento de las redes de apoyo primario y el papel de Enfermería como soporte para las gestantes; así como la revisión de las condiciones de hospitalización. La preparación para el impacto emocional y las consecuencias de afrontar una preeclampsia es un aspecto que se pudiera abordar durante el control prenatal.

Disertación endocrina de la preeclampsia y propuesta de una hipótesis Endocrine dissertation on preeclampsia and proposal of a hypothesis

Se propone que la facies androgenizada en las embarazadas podría servir como elemento clínico para la búsqueda de la preeclampsia, con el fin de lograr un enfoque preventivo. El balance de las prostaglandinas vasodilatadoras y vasoconstrictoras es, en último término, responsable del control de la presión arterial en la gestante. Para ello se debe lograr un adecuado equilibrio en la producción de hormonas gestacionales; de ellas parece ser fundamental la dihidroprogesterona que se obtiene a través de la acción de la enzima 5-alfa reductasa. En el metabolismo de los andrógenos esta enzima cumple un papel único al transformar los andrógenos circulantes en la hormona trófica, la dihidrotestosterona. La hipótesis propone que la utilización androgénica de la enzima 5-alfa reductasa durante la gestación alteraría la producción de dihidroprogesterona con lo cual crearía un desequilibrio entre las diferentes hormonas y, finalmente, entre las prostaglandinas.

The hypothesis that an androgenized facies In a pregnant woman could serve as a clinical clue for the search of preeclampsia, making It possible to apply a preventive approach is proposed. The balance between dilator and constrictor prostaglandins controls blood pressure during pregnancy; to keep such a balance an adequate equilibrium in the production of hormones, particularly dihydroprogesterone (DHP, is necessary. DHP is obtained through the action of 5-alpha reductase, which in androgen metabolism has the unique role of transforming circulating androgens into the trophic hormone dihydrotestosterone. The hypothesis proposes that androgenic utilization of 5- alpha reductase during pregnancy could alter the production of DHP I generating a lack of equilibrium among the various hormones, prostaglandins included.

Full Text Available Introducción: la lactancia materna es la única forma natural de alimentar al bebé, y una forma inigualable de facilitar el alimento ideal para su crecimiento y desarrollo. Métodos: se realizó un estudio descriptivo, transversal, para evaluar deseos, aptitudes y conocimientos sobre lactancia materna en el tercer trimestre de 114 gestantes del Policlínico "Mártires del 9 de Abril", de San José de las Lajas. Entre marzo de 2010 y de 2011 se valoraron sus historias de salud individual y familiar, y se aplicó a tal efecto un cuestionario con 22 preguntas. Resultados: la información se incorporó a una base de datos y se utilizó para el análisis el estadígrafo chi cuadrado, que se consideró significativo con p< 0,05. La totalidad de las gestantes deseaban amamantar. Dos terceras partes se consideraron aptas o muy aptas para hacerlo, y que poseían los conocimientos necesarios para lograrlo, pero solo algo más de la quinta parte demostró que los poseía. La mayoría de las futuras madres se encontraban entre los 20 y 35 años, el nivel de escolaridad más frecuentemente alcanzado fue el técnico o preuniversitario (en 60 de ellas, para el 52,6 %, y el 46,5 % de las gestantes mantenían una unión consensuada, el 40,3 % eran casadas, y 15 solteras (13,2 %, aspectos que, indiscutiblemente influyen en los resultados. Conclusiones: además de otros resultados alcanzados, la investigación arrojó que aunque la totalidad de las gestantes en su tercer trimestre deseaban lactar a su futuro bebé y las dos terceras partes se consideraban aptas o muy aptas para hacerlo y con conocimientos suficientes al respecto, solo algo más de la quinta parte demostró efectivamente poseerlos.

Full Text Available JUSTIFICATIVA E OBJETIVOS: Está bem estabelecido que a técnica anestésica de escolha para cesariana eletiva é a anestesia regional. Porém, em gestantes com hipertensão intracraniana e infecção do sistema nervoso central esta técnica deve ser evitada. O objetivo deste artigo é relatar o manejo anestésico de uma gestante, com hipertensão intracraniana secundária à meningite tuberculosa, que foi submetida à cesariana eletiva. RELATO DO CASO: Paciente branca, 32 anos, 60 kg, 1,62 m de estatura, na 36ªsemana de idade gestacional, agendada para interrupção cirúrgica da gestação por apresentar-se tetraparética, com hidrocefalia decorrente de meningite tuberculosa. Escolheu-se a anestesia geral para a cesariana com indução em seqüência rápida e manobra de Sellick para a intubação traqueal. As drogas utilizadas foram tiopental (250 mg, rocurônio (50 mg, fentanil (100 µg e lidocaína (60 mg por via venosa. A indução anestésica foi suave e mantida com isoflurano até o início do fechamento da pele da paciente, com mínimas alterações de seus sinais vitais e do recém-nascido, que recebeu índice de Apgar 8 e 9, no 1º e 5º minutos, respectivamente. A paciente despertou precocemente, sem deficits neurológicos adicionais. CONCLUSÕES: A anestesia geral ainda é a técnica anestésica preferida para cesariana em gestantes com hipertensão intracraniana, utilizando-se drogas de meia-vida curta e que tenham mínima interferência na pressão intracraniana e no recém-nascido.JUSTIFICATIVA Y OBJETIVOS: Está bien establecido que la técnica anestésica de elección para cesárea electiva es la anestesia regional. Sin embargo, en gestantes con hipertensión intracraneal e infección del sistema nervioso central esta técnica debe ser evitada.

Prevalencia de anemia en gestantes, Hospital Regional de Pucallpa, Perú

Full Text Available Las encuestas demográficas de salud y población del Perú indican que las tasas globales de fecundidad, la proporción de adolescentes embarazadas y la mortalidad maternoinfantil son más altas en la selva que en otras zonas del país. Las parasitosis intestinales endémicas agravan el riesgo de anemia ya generalmente presente en las embarazadas por deficiencias de hierro, ácido fólico y otros nutrientes. En muchos países latinoamericanos, esa es la complicación más frecuente del embarazo y está asociada con partos pretérmino, bajo peso al nacer y mortalidad perinatal. Los estudios realizados sobre este tema en la selva peruana son escasos y no se dispone de estimaciones confiables de la prevalencia de anemia durante la gestación. Los autores se propusieron determinar la prevalencia de anemia en mujeres gestantes que acudían al Hospital Regional de Pucallpa, en la selva del Perú, entre enero de 1993 y junio de 1995. El estudio de corte transversal se basó en los registros de control prenatal y de parto de 1 015 embarazadas y permitió estudiar la asociación entre la prevalencia de anemia y variables como edad cronológica, escolaridad, número de gestaciones previas y peso de la madre al inicio del embarazo. También se compararon los valores de la hemoglobina materna con el peso de los recién nacidos. La prevalencia de anemia en la población de gestantes fue de 70,1%, valor que no se modificó por efecto de la edad materna, la escolaridad ni el intervalo intergenésico. La prevalencia de anemia se asoció directamente con el número de gestaciones e inversamente con la ganancia de peso durante el embarazo. La tasa de mortalidad perinatal fue de 37,7 por 1 000 nacidos. Ni esta tasa ni el peso de los recién nacidos resultaron asociados con el grado de anemia de la madre. El análisis de regresión multivariado muestra que el peso de la madre al inicio de la gestación (P = 0,0001, el peso ganado durante la gestación (P = 0

1998-10-01

Full Text Available Tres recientes estudios han confirmado que la aspirina no aporta ningún beneficio en la prevención de la pre-eclampsia o en reducir los efectos de esta en los recién nacidos. Sin embargo, y a pesar de la evidencia cada vez mayor de ineficacia, muchos continúan usándola de rutina con este fin. EI resultado de un primer ensayo clínico aleatorizado con 2.539 mujeres en alto riesgo para presentar pre-eclampsia, llevado a cabo en el National Institute of Child Health and Human Development en los Estados Unidos, demostró categóricamente que el tratamiento preventivo con aspirina no sirve; las diferencias halladas frente al placebo no fueron estadísticamente significativas, tomando para el estudio mujeres con diabetes previa, hipertensión arterial, o antecedentes de pre-eclampsia. Tampoco hubo ninguna diferencia en cuanto al número de partos pretérmino, bajo peso para la edad gestacional y mortalidad.

Full Text Available Objetivos. Determinar los niveles de plomo (Pb en gestantes y neonatos en la ciudad de La Oroya, Perú. Materiales y métodos. Se realizó un estudio transversal. La población estuvo conformada por gestantes residentes durante al menos dos años en la ciudad de La Oroya, cuando operaban normalmente las fundiciones de Pb, cobre y zinc. Se obtuvo muestras de sangre de la gestante antes del parto y luego del parto se tomaron muestras de placenta y sangre del cordón umbilical. El nivel de Pb de dichas muestras fue evaluado por espectrometría de absorción atómica con horno de grafito. Se determinaron regresiones cuadráticas y correlaciones de Pearson. Resultados. Se evaluó cuarenta partos normales. Los niveles promedio de Pb en la sangre materna, cordon umbilical y placenta fueron 27,4 ± 15,6 ug/dL; 19,0 ± 12,6 ug/dL y 319,0 ± 215,9 ug/100 g, respectivamente. El 67,5% de los neonatos tuvieron más de 10 ug/dL de Pb. El nivel de Pb de la sangre del cordón umbilical representó el 69,4% del nivel de Pb en sangre materna. Los coeficientes de correlación entre el Pb de la sangre materna y cordón umbilical, sangre materna y placenta, placenta y sangre del cordón umbilical fueron 0,36; 0,48 y 0,33, respectivamente. Conclusiones. Cuando funcionaba la fundición, las gestantes y recién nacidos tenían concentraciones elevadas de Pb en sangre. Las concentraciones de Pb en la placenta y cordón umbilical tuvieron una correlación moderada con el Pb de la sangre materna. El Pb de la sangre materna y cordón umbilical fue 1,5 veces más alto que los de zonas más alejadas

Full Text Available Preeclampsia is a common complication of pregnancy associated with high maternal morbidity and mortality and intrauterine fetal growth restriction. There is extensive evidence that the reduction of uteroplacental blood flow in this syndrome results from the toxic combination of hypoxia, imbalance of angiogenic and antiangiogenic factors, inflammation, and deranged immunity. Women treated for preeclampsia also have an increased risk for cardiovascular and renal disease. At present it is unclear if the increased cardiovascular and renal disease risks are due to residual and or progressive effects of endothelial damage from the preeclampsia or from shared risk factors between preeclampsia and cardiac disease. Moreover, it appears that endothelin-1 signaling may play a central role in the hypertension associated with preeclampsia. In this paper, we discuss emerging data on the pathogenesis of preeclampsia and review therapeutic options.

Full Text Available ResumenIntroducción y objetivos: La hipertensión inducida por el embarazo o preeclampsia presenta características fisiopatológicas similares a las de la aterosclerosis y las enfermedades cardiovasculares. El propósito del estudio fue identificar los factores de riesgo aterogénico y su relación en la preeclampsia. Método: Se realizó una investigación descriptiva de tipo transversal, con 50 pacientes en el tercer trimestre del embarazo. Mediante la entrevista se establecieron el peso y la talla, para calcular el índice de masa corporal. La tensión arterial > 140/90 mmHg acompañada de edema y proteinuria en el embarazo, se clasificó como hipertensión arterial. Se tomaron muestras de sangre para determinar los valores de colesterol sérico, triglicéridos y HDL. Las variables se expresaron en porcentajes. Resultados: En cada paciente se analizó el número de factores de riesgo y sus asociaciones. Los resultados más relevantes consistieron en que el 76 % presentó sobrepeso u obesidad. En cuanto al síndrome de preeclampsia, se mostró en el 30 % con un riesgo relativo de 3 veces más que las normolipídicas, y 30 % tuvo un índice aterogénico elevado. Conclusiones: La dislipidemia es un factor de riesgo aterogénico de importancia, y en conjunto constituyen un factor de riesgo para la preeclampsia. El incremento del índice aterogénico aumenta la susceptibilidad a la aterogénesis en la preeclampsia. La dislipidemia aparenta ser el punto de inicio de esta cadena de sucesos. El estudio del papel de la dislipidemia podría contribuir a la comprensión de los mecanismos de disfunción endotelial en la preeclampsia. / AbstractIntroduction and Objectives: Pregnancy−induced hypertension or preeclampsia presents pathophysiological features similar to atherosclerosis and cardiovascular disease.

Adenosine is an endogenous nucleoside with pleiotropic effects in different physiological processes including circulation, renal blood flow, immune function, or glucose homeostasis. Changes in adenosine membrane transporters, adenosine receptors, and corresponding intracellular signalling network associate with development of pathologies of pregnancy, including preeclampsia. Preeclampsia is a cause of maternal and perinatal morbidity and mortality affecting 3-5% of pregnancies. Since the proposed mechanisms of preeclampsia development include adenosine-dependent biological effects, adenosine membrane transporters and receptors, and the associated signalling mechanisms might play a role in the pathophysiology of preeclampsia. Preeclampsia associates with increased adenosine concentration in the maternal blood and placental tissue, likely due to local hypoxia and ischemia (although not directly demonstrated), microthrombosis, increased catecholamine release, and platelet activation. In addition, abnormal expression and function of equilibrative nucleoside transporters is described in foetoplacental tissues from preeclampsia; however, the role of adenosine receptors in the aetiology of this disease is not well understood. Adenosine receptors activation may be related to abnormal trophoblast invasion, angiogenesis, and ischemia/reperfusion mechanisms in the placenta from preeclampsia. These mechanisms may explain only a low fraction of the associated abnormal transformation of spiral arteries in preeclampsia, triggering cellular stress and inflammatory mediators release from the placenta to the maternal circulation. Although increased adenosine concentration in preeclampsia may be a compensatory or adaptive mechanism favouring placental angiogenesis, a poor angiogenic state is found in preeclampsia. Thus, preeclampsia-associated complications might affect the cell response to adenosine due to altered expression and activity of adenosine receptors, membrane transporters

Microvascular remodelling in preeclampsia: quantifying capillary rarefaction accurately and independently predicts preeclampsia.

Science.gov (United States)

Antonios, Tarek F T; Nama, Vivek; Wang, Duolao; Manyonda, Isaac T

2013-09-01

Preeclampsia is a major cause of maternal and neonatal mortality and morbidity. The incidence of preeclampsia seems to be rising because of increased prevalence of predisposing disorders, such as essential hypertension, diabetes, and obesity, and there is increasing evidence to suggest widespread microcirculatory abnormalities before the onset of preeclampsia. We hypothesized that quantifying capillary rarefaction could be helpful in the clinical prediction of preeclampsia. We measured skin capillary density according to a well-validated protocol at 5 consecutive predetermined visits in 322 consecutive white women, of whom 16 subjects developed preeclampsia. We found that structural capillary rarefaction at 20-24 weeks of gestation yielded a sensitivity of 0.87 with a specificity of 0.50 at the cutoff of 2 capillaries/field with the area under the curve of the receiver operating characteristic value of 0.70, whereas capillary rarefaction at 27-32 weeks of gestation yielded a sensitivity of 0.75 and a higher specificity of 0.77 at the cutoff of 8 capillaries/field with area under the curve of the receiver operating characteristic value of 0.82. Combining capillary rarefaction with uterine artery Doppler pulsatility index increased the sensitivity and specificity of the prediction. Multivariable analysis shows that the odds of preeclampsia are increased in women with previous history of preeclampsia or chronic hypertension and in those with increased uterine artery Doppler pulsatility index, but the most powerful and independent predictor of preeclampsia was capillary rarefaction at 27-32 weeks. Quantifying structural rarefaction of skin capillaries in pregnancy is a potentially useful clinical marker for the prediction of preeclampsia.

Preeclampsia encompasses multiple conditions of varying severity. We examined the recurrence and familial aggregation of preeclampsia by timing of onset, which is a marker for severity. We ascertained personal and family histories of preeclampsia for women who delivered live singletons in Denmark in 1978-2008 (almost 1.4 million pregnancies). Using log-linear binomial regression, we estimated risk ratios for the associations between personal and family histories of preeclampsia and the risk of early-onset (before 34 weeks of gestation, which is typically the most severe), intermediate-onset (at 34-36 weeks of gestation), and late-onset (after 36 weeks of gestation) preeclampsia. Previous early-, intermediate-, or late-onset preeclampsia increased the risk of recurrent preeclampsia with the same timing of onset 25.2 times (95% confidence interval (CI): 21.8, 29.1), 19.7 times (95% CI: 17.0, 22.8), and 10.3 times (95% CI: 9.85, 10.9), respectively, compared with having no such history. Preeclampsia in a woman's family was associated with a 24%-163% increase in preeclampsia risk, with the strongest associations for early- and intermediate-onset preeclampsia in female relatives. Preeclampsia in the man's family did not affect a woman's risk of early-onset preeclampsia and was only weakly associated with her risks of intermediate- and late-onset preeclampsia. Early-onset preeclampsia appears to have the largest genetic component, whereas environmental factors likely contribute most to late-onset preeclampsia. The role of paternal genes in the etiology of preeclampsia appears to be limited.

Apego materno fetal em gestantes que vivem com HIV/Aids

Full Text Available A gestação no contexto do HIV/Aids é geralmente acompanhada de intensa ansiedade devido à possível transmissão materno infantil do vírus. Este estudo investigou o apego materno fetal em gestantes que viviam com HIV (n = 88, em comparação a gestantes não portadoras do vírus (n = 79, através da Escala de Apego Materno fetal. Os resultados não revelaram diferenças entre as gestantes quanto ao escore total de apego materno fetal. Entretanto, os dados sugerem que o apego materno fetal pode se manifestar de maneira peculiar entre as gestantes que vivem com HIV/Aids: as interações mãe-bebê parecem focar o momento presente da gestação, e os cuidados de saúde com o bebê parecem atrelados àqueles voltados à saúde materna diante da infecção. É possível que a escala não seja suficientemente sensível para eventuais diferenças associadas ao contexto do HIV/Aids. Sugere-se que novos estudos revisem os itens da escala visando maior aproximação das particularidades suscitadas pela infecção quanto ao apego materno fetal.

Nutritional approach to preeclampsia prevention.

Achamrah, Najate; Ditisheim, Agnès

2018-05-01

Although not fully understood, the physiopathology of preeclampsia is thought to involve an abnormal placentation, diffuse endothelial cell dysfunction and increased systemic inflammation. As micronutrients play a key role in placental endothelial function, oxidative stress and expression of angiogenic factors, periconceptional micronutrient supplementation has been proposed to reduce the risk of preeclampsia. However, recent studies reported conflicting results. Calcium intake (>1 g/day) may reduce the risk of preeclampsia in women with low-calcium diet. Data from recently updated Cochrane reviews did not support routine supplementation of vitamins C, E or D for either the prevention or treatment of preeclampsia. Evidences are also poor to support zinc or folic acid supplementation for preeclampsia prevention. Dark chocolate, flavonoid-rich food, and long-chain polyunsaturated fatty acids might also be candidates for prevention of preeclampsia. Through antioxidant, anti-inflammatory or vasoactive proprieties, micronutrients are good candidates for preeclampsia prevention. Calcium supplementation is recommended to prevent preeclampsia in women with low-calcium intake. Despite positive clinical and in-vitro data, strong evidence to support periconceptional supplementation of other micronutrients for preeclampsia risk-reduction is still lacking. Further studies are also needed to evaluate the benefit of nutritional supplementation such as chocolate and long-chain polyunsaturated fatty acids.

To determine whether assisted reproductive technology (ART) cycles involving cryopreserved-warmed embryos are associated with the development of preeclampsia. Retrospective cohort study. IVF clinics and hospitals. A total of 15,937 births from ART: 9,417 singleton and 6,520 twin. We used linked ART surveillance, birth certificate, and maternal hospitalization discharge data, considering resident singleton and twin births from autologous or donor eggs from 2005-2010. We compared the frequency of preeclampsia diagnosis for cryopreserved-warmed versus fresh ET and used multivariable logistic regression to adjust for confounders. Among pregnancies conceived with autologous eggs resulting in singletons, preeclampsia was greater after cryopreserved-warmed versus fresh ET (7.51% vs. 4.29%, adjusted odds ratio = 2.17 [95% CI 1.67-2.82]). Preeclampsia without and with severe features, preeclampsia with preterm delivery, and chronic hypertension with superimposed preeclampsia were more frequent after cryopreserved-warmed versus fresh ET (3.99% vs. 2.55%; 2.95% vs. 1.41%; 2.76 vs. 1.48%; and 0.95% vs. 0.43%, respectively). Among pregnancies from autologous eggs resulting in twins, the frequency of preeclampsia with severe features (9.26% vs. 5.70%) and preeclampsia with preterm delivery (14.81% vs. 11.74%) was higher after cryopreserved versus fresh transfers. Among donor egg pregnancies, rates of preeclampsia did not differ significantly between cryopreserved-warmed and fresh ET (10.78% vs. 12.13% for singletons and 28.0% vs. 25.15% for twins). Among ART pregnancies conceived using autologous eggs resulting in live births, those involving transfer of cryopreserved-warmed embryos, as compared with fresh ETs, had increased risk for preeclampsia with severe features and preeclampsia with preterm delivery.

Preeclampsia is a multi-system disorder involved in pregnancy without an effective treatment except delivery. The precise pathogenesis of this complicated disorder is still not completely understood. The objective of this study is to evaluate the alterations of protein expression and phosphorylations that are important in regulating placental cell function in preterm and term preeclampsia. Using the Protein Pathway Array, 38 proteins in placental tissues were found to be differentially expressed between preterm preeclampsia and gestational age matched control, while 25 proteins were found to be expressed differentially between term preeclampsia and matched controls. Among these proteins, 16 proteins and their associated signaling pathways overlapped between preterm and term preeclampsia, suggesting the common pathogenesis of two subsets of disease. On the other hand, many proteins are uniquely altered in either preterm or term preeclampsia and correlated with severity of clinical symptoms and outcomes, therefore, providing molecular basis for these two subsets of preeclampsia. Furthermore, the expression levels of some of these proteins correlated with neonatal small for gestational age (PAI-1 and PAPP-A) and adverse outcomes (Flt-1) in women with preterm preeclampsia. These proteins could potentially be used as candidate biomarkers for predicting outcomes of preeclampsia.

Carl H. Backes

2011-01-01

Full Text Available Preeclampsia is a multiorgan, heterogeneous disorder of pregnancy associated with significant maternal and neonatal morbidity and mortality. Optimal strategies in the care of the women with preeclampsia have not been fully elucidated, leaving physicians with incomplete data to guide their clinical decision making. Because preeclampsia is a progressive disorder, in some circumstances, delivery is needed to halt the progression to the benefit of the mother and fetus. However, the need for premature delivery has adverse effects on important neonatal outcomes not limited to the most premature infants. Late-preterm infants account for approximately two thirds of all preterm deliveries and are at significant risk for morbidity and mortality. Reviewed is the current literature in the diagnosis and obstetrical management of preeclampsia, the outcomes of late-preterm infants, and potential strategies to optimize fetal outcomes in pregnancies complicated by preeclampsia.

Nora Alejandra Zuluaga

2004-06-01

Full Text Available La preeclampsia es considerada un problema de salud pública debido a su alta prevalencia. Muchas investigaciones coinciden en que su origen se relaciona con la interacción entre factores genéticos y ambientales. Por esta razón, múltiples estudios han explorado tales factores genéticos tratando de identificar regiones cromosómicas y genes candidatos cuyas variantes se relacionen con una mayor susceptibilidad a la enfermedad. Diversos estudios de asociación han identificado algunos genes de susceptibilidad a la preeclampsia, pero los resultados no se han replicado consistentemente en todas las poblaciones, quizá por su complejidad clínica y genética. El levantamiento de mapas de genes y regiones cromosómicas basado en análisis de ligamiento ha mostrado resultados interesantes con algunos marcadores en los cromosomas 2 y 4. En este sentido, hay muchas expectativas con respecto a los genes localizados en tales regiones candidatas, debido a que la identificación de los factores de riesgo genético podría ayudar al entendimiento de esta condición y en proveer claves para su prevención y tratamiento.

Full Text Available OBJECTIVE: To determine the prevalence of reagent serology for suspected acute toxoplasmosis in pregnant women and to describe clinical, laboratory and therapeutic profiles of mothers and their children. METHODS: A retrospective study was conducted with IgM-anti-Toxoplasma gondii-reagent pregnant women and their children who attended the public health system in the state of Paraná, Southern Brazil, from January 2001 to December 2003. Information were obtained from clinical, laboratory (ELISA IgM/IgG and ultrasonographic data and from interviews with the mothers. To test the homogeneity of the IgM indices in relation to the treatment used, the Pearson's Chi-square test was applied. Comparisons were considered significant at a 5% level. RESULTS: Two hundred and ninety (1.0% cases of suspected IgM-reagent infection were documented, with a prevalence of 10.7 IgM-reagent women per 1,000 births. Prenatal care started within the first 12 weeks for 214/290; 146/204 were asymptomatic. Frequent complaints included headaches, visual disturbance and myalgia. Ultrasonography revealed abnormalities in 13 of 204 pregnancies. Chemoprophylaxis was administered to 112/227; a single ELISA test supported most decisions to begin treatment. Pregnant women with IgM indices =2.000 tended to be treated more often. Among exposed children, 44/208 were serologically followed up and all were IgG-reagent, and three IgM-reagent cases showed clinical symptoms. CONCLUSIONS: The existence of pregnant women with laboratorially suspected acute toxoplasmosis who were not properly followed up, and of fetuses that were not adequately monitored, shows that basic aspects of the prenatal care are not being systematically observed. There is need of implementing a surveillance system of pregnant women and their children exposed to T. gondii.OBJETIVO: Determinar a prevalência de gestantes com sorologia reagente suspeita de toxoplasmose aguda e descrever as variáveis maternas e do

Role of fetal DNA in preeclampsia (review).

Preeclampsia is an autoimmune disorder characterized by hypertension. It begins with abnormal cytotrophoblast apoptosis, which leads to inflammation and an increase in the levels of anti-angiogenic factors followed by the disruption of the angiogenic status. Increased levels of fetal DNA and RNA coming from the placenta, one of the most commonly affected organs in pregnancies complicated by preeclampsia, have been found in pregnant women with the condition. However, it remains unknown as to whether this is a cause or a consequence of preeclampsia. Few studies have been carried out on preeclampsia in which an animal model of preeclampsia was induced by an injection of different types of DNA that are mimic fetal DNA and provoke inflammation through Toll-like receptor 9 (TLR9) or cyclic guanosine monophosphate-adenosine monophosphate (cGAMP). The specific mechanisms involved in the development of preeclampsia are not yet fully understood. It is hypothesized that the presence of different fragments of fetal DNA in maternal plasma may cause for the development of preeclampsia. The function of DNase during preeclampsia also remains unresolved. Studies have suggested that its activity is decreased or the DNA is protected against its effects. Further research is required to uncover the pathogenesis of preeclampsia and focus more on the condition of patients with the condition.

New-onset postpartum preeclampsia is a poorly defined condition that accounts for a significant percentage of eclampsia cases. It is unclear whether new-onset postpartum preeclampsia is a different disorder from or belongs to the same spectrum of classic antepartum preeclampsia. The objective of this study was to compare the clinical presentation and pregnancy outcomes of antepartum preeclampsia and new-onset postpartum preeclampsia. A retrospective study including 92 patients with antepartum preeclampsia and 92 patients with new-onset postpartum preeclampsia was performed. Clinical presentation and pregnancy outcomes were compared. Chi-square test was used to analyze categorical variables, and independent t -test and Mann-Whitney U -test for numerical variables. P -values of presentation, laboratory markers and pregnancy outcomes. New-onset postpartum preeclampsia has a distinct patient profile and clinical presentation than antepartum preeclampsia, suggesting they may represent different disorders. Characterization of a patient profile with increased risk of developing this condition will help clinicians to identify patients at risk and provide early and targeted interventions to decrease the morbidity associated with this condition.

Preeclampsia is a multisystemic disorder of unknown etiology. Recently,endothelial damage has been implicated in its cause. The objective of thisstudy was to determine the role of interleukins in the etiology ofpreeclampsia. 32 primigravidas with preeclampsia but without any clinicalevidence of infection and 32 age-matched primigravidas with uncomplicatednormal pregnancies were investigated. Phlebotomy was performed at 32 weeks ofgestation and blood collected for immunoassay of interleukin-2 (IL-2),interleukin-2 receptor (IL-2R), interleukin-6 (IL-6), interleukin-8 (IL-8)andvinterleukin-10 (IL-10), using commercially available immunoassay kits.Although the maternal plasma concentrations of IL-2 and IL-2R were slightlyhigher in normal pregnant women (76.3+-13.7 pg/mL and 526+-47.1pg/mL,respectively) than in women with preeclampsia (57.8+-1.08 pg/mL and476.9+-3.9pg/mL, respectively), the difference was not statistically significant(P>0.05). However, maternal plasma IL-6 and IL-8 concentrations weresignificantly higher (P<0.05) in normal pregnancy (158.0+-35.4 pg/mL and5163.6+- 800pg/mL, respectively) than in pregnancy complicated withpreeclampsia (60.0+-13.7 pg/mL and 2495.8+-729 pg/mL, respectively). On thepther hand, maternal plasma concentration of IL-10 was significantly higher(P<0.05) in preeclampsia (93.2+-24.1 pg/mL) than in normal pregnancy(31.0+-7.0 pg/mL). It is concluded that the elevated maternal plasma IL-10concentration in preeclampsia may be protective response to maternalimmunorejection. (author)

Preeclampsia is a pregnancy-specific disease characterized by new onset hypertension and proteinuria after 20 wk of gestation. It is a leading cause of maternal and fetal morbidity and mortality worldwide. Exciting discoveries in the last decade have contributed to a better understanding of the molecular basis of this disease. Epidemiological, experimental, and therapeutic studies from several laboratories have provided compelling evidence that an antiangiogenic state owing to alterations in circulating angiogenic factors leads to preeclampsia. In this review, we highlight the role of key circulating antiangiogenic factors as pathogenic biomarkers and in the development of novel therapies for preeclampsia. PMID:26292986

Full Text Available Preeclampsia is the main cause of maternal mortality and is associated with a five-fold increase in perinatal mortality in developing countries. In spite of this, the etiology of preeclampsia is unknown. The present article analyzes the contradictory results of the use of calcium supplementation in the prevention of preeclampsia, and tries to give an explanation of these results. The proposal of an integrative model to explain the clinical manifestations of preeclampsia is discussed. In this proposal we suggest that preeclampsia is caused by nutritional, environmental and genetic factors that lead to the creation of an imbalance between the free radicals nitric oxide, superoxide and peroxynitrate in the vascular endothelium. The adequate interpretation of this model would allow us to understand that the best way of preventing preeclampsia is the establishment of an adequate prenatal control system involving adequate antioxidant vitamin and mineral supplementation, adequate diagnosis and early treatment of asymptomatic urinary and vaginal infections. The role of infection in the genesis of preeclampsia needs to be studied in depth because it may involve a fundamental change in the prevention and treatment of preeclampsia.

Full Text Available Background The main causes of maternal mortality in Indonesia are pre-eclampsia, hemorrhage, and infection. Oxidative stress has a primary role in pre-eclampsia and one of its parameters is 8-isoprostane serum level. The objective of this study is to measure 8-isoprostane and to analyze the relationship between 8-isoprostane level and birth weight in pre-eclampsia. Methods A cross-sectional study involving 23 pre-eclampsia and 29 normotensive pregnant women with normal or cesarean delivery at Dr. Kariadi Hospital Semarang from January to May 2011. Collected maternal blood samples were assessed for 8-Isoprostane levels by means of a specific ELISA kit. Neonatal birth weight was measured immediately after delivery by means of calibrated baby scales. Differences in 8-isoprostane levels between pre-eclampsia and normotensive women were assessed using independent t-test for normal distributed data, and the Mann-Whitney test for non-normally distributed data. Results Mean 8-isoprostane level was significantly higher in women with pre-eclampsia than in normotensive women (62.52 ± 12.19 pg/mL vs 28.64 ± 8.81 pg/mL (p<0.05. Low birth weight was twice as frequent in pre-eclampsia than in normotensives. There was no correlation between 8-isoprostane serum level and neonatal birth weight in pre-eclampsia. Conclusion The level of 8-isoprostane was higher in pre-eclampsia than in normotensives. It is recommended to conduct further studies to determine whether 8-isoprostane may be used as a predictive marker of pre-eclampsia.

Forty-four pregnant patients (gestional age, 20-42 weeks; 18 CAH, 17 PE, 9 N were evaluated for calciuria, proteinuria, plasma uric acid and blood pressure. Patients with PE (82 ± 15.1 mg/24 h showed significantly lower calciuria (P<0.05 than the group with CAH (147 ± 24.9 mg/24 h and the N group (317 ± 86.0 mg/24 h (P<0.05, Student t-test. Plasma uric acid was significantly higher in the PE group (6.1 ± 0.38 mg/dl than the CAH group (5.0 ± 0.33 mg/dl; P<0.05, which also presented higher proteinuria levels, although the difference was not statistically significant. Diastolic and systolic blood pressure did not differ between the PE (164 ± 105 mmHg and CAH (164 ± 107 mmHg groups. Calciuria was significantly lower in the group with preeclampsia than in the group with chronic arterial hypertension. We conclude that calciuria can be a further factor for identifying preeclampsia

The Aspirin for Evidence-Based Preeclampsia Prevention trial was a multicenter study in women with singleton pregnancies. Screening was carried out at 11-13 weeks' gestation with an algorithm that combines maternal factors and biomarkers (mean arterial pressure, uterine artery pulsatility index, and maternal serum pregnancy-associated plasma protein A and placental growth factor). Those with an estimated risk for preterm preeclampsia of >1 in 100 were invited to participate in a double-blind trial of aspirin (150 mg/d) vs placebo from 11-14 until 36 weeks' gestation. Preterm preeclampsia with delivery at preeclampsia in the Aspirin for Evidence-Based Preeclampsia Prevention trial. This was a secondary analysis of data from the trial. The proportion of prescribed tablets taken was used as an overall measure of compliance. Logistic regression analysis was used to estimate the effect of aspirin on the incidence of preterm preeclampsia according to compliance of preeclampsia at screening and the participating center. The choice of cut-off of 90% was based on an exploratory analysis of the treatment effect. Logistic regression analysis was used to investigate predictors of compliance ≥90% among maternal characteristics and medical history. Preterm preeclampsia occurred in 5/555 (0.9%) participants in the aspirin group with compliance ≥90%, in 8/243 (3.3%) of participants in the aspirin group with compliance preeclampsia was 0.24 (95% confidence interval, 0.09-0.65) for compliance ≥90% and 0.59 (95% confidence interval, 0.23-1.53) for compliance preeclampsia and negatively associated with smoking, maternal age preeclampsia in a previous pregnancy. The beneficial effect of aspirin in the prevention of preterm preeclampsia appears to depend on compliance. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available Introduction: Preeclampsia is a common disorder that is a leading cause of perinatal and maternal morbidity and mortality; however its specific etiology has still remained obscure.The first step in preventing preeclampsia is early detection of women at risk. Since there is no valid and reliable screening test, appropriate diagnostic and screening tests are necessary, which are inexpensive, non-invasive and beneficial for pregnant women. Therefore, regarding the role of selenium as an antioxidant in the prevention preeclampsia, this study was designed which aimed to determine the prognostic value of plasma selenium levels in the diagnosis of preeclampsia in primigravida women Methods: In a nested case control design, a sample of 650 normal primigravida women of 24-28 weeks participated in the study. Subjects who involved the case group were followed up for 3 months and 38 were affected by preeclampsia. Blood samples were obtained from these 38patients as well as from 38 subjects as their matched controls. Moreover, the amount of selenium was measured by atomic absorption spectrometry. Results: The mean level of selenium in blood plasma of the cases was significantly lower than in their matched controls. The present study findings revealed that pregnant women with serum Se < 66.1 μg/L had a significantly increased risk of preeclampsia. Conclusion: Lower plasma selenium level in women destines to suffering from preeclampsia which confirms the destructive effect of selenium deficiency as an antioxidant in etiopathology of preeclampsia. Measurement of plasma selenium can improve the prediction of preeclampsia; thus, it seems that plasma selenium level test owns an acceptable sensitivity and specificity for predicting preeclampsia.

Genetic Aspects of Preeclampsia and the HELLP Syndrome

Mortensen, Jan Helge; Nagy, Bálint

Both preeclampsia and the HELLP syndrome have their origin in the placenta. The aim of this study is to review genetic factors involved in development of preeclampsia and the HELLP syndrome using literature search in PubMed. A familial cohort links chromosomes 2q, 5q, and 13q to preeclampsia. The chromosome 12q is coupled with the HELLP syndrome. The STOX1 gene, the ERAP1 and 2 genes, the syncytin envelope gene, and the −670 Fas receptor polymorphisms are involved in the development of preeclampsia. The ACVR2A gene on chromosome 2q22 is also implicated. The toll-like receptor-4 (TLR-4) and factor V Leiden mutation participate both in development of preeclampsia and the HELLP syndrome. Carriers of the TT and the CC genotype of the MTHFR C677T polymorphism seem to have an increased risk of the HELLP syndrome. The placental levels of VEGF mRNA are reduced both in women with preeclampsia and in women with the HELLP syndrome. The BclI polymorphism is engaged in development of the HELLP syndrome but not in development of severe preeclampsia. The ACE I/D polymorphism affects uteroplacental and umbilical artery blood flows in women with preeclampsia. In women with preeclampsia and the HELLP syndrome several genes in the placenta are deregulated. Preeclampsia and the HELLP syndrome are multiplex genetic diseases. PMID:24991435

Vascular dysfunction in preeclampsia.

Science.gov (United States)

Brennan, Lesley J; Morton, Jude S; Davidge, Sandra T

2014-01-01

Preeclampsia is a complex disorder which affects an estimated 5% of all pregnancies worldwide. It is diagnosed by hypertension in the presence of proteinuria after the 20th week of pregnancy and is a prominent cause of maternal morbidity and mortality. As delivery is currently the only known treatment, preeclampsia is also a leading cause of preterm delivery. Preeclampsia is associated with maternal vascular dysfunction, leading to serious cardiovascular risk both during and following pregnancy. Endothelial dysfunction, resulting in increased peripheral resistance, is an integral part of the maternal syndrome. While the cause of preeclampsia remains unknown, placental ischemia resulting from aberrant placentation is a fundamental characteristic of the disorder. Poor placentation is believed to stimulate the release of a number of factors including pro- and antiangiogenic factors and inflammatory activators into the maternal systemic circulation. These factors are critical mediators of vascular function and impact the endothelium in distinctive ways, including enhanced endothelial oxidative stress. The mechanisms of action and the consequences on the maternal vasculature will be discussed in this review. © 2013 John Wiley & Sons Ltd.

Animal models of preeclampsia; uses and limitations.

McCarthy, F P

2012-01-31

Preeclampsia remains a leading cause of maternal and fetal morbidity and mortality and has an unknown etiology. The limited progress made regarding new treatments to reduce the incidence and severity of preeclampsia has been attributed to the difficulties faced in the development of suitable animal models for the mechanistic research of this disease. In addition, animal models need hypotheses on which to be based and the slow development of testable hypotheses has also contributed to this poor progress. The past decade has seen significant advances in our understanding of preeclampsia and the development of viable reproducible animal models has contributed significantly to these advances. Although many of these models have features of preeclampsia, they are still poor overall models of the human disease and limited due to lack of reproducibility and because they do not include the complete spectrum of pathophysiological changes associated with preeclampsia. This review aims to provide a succinct and comprehensive assessment of current animal models of preeclampsia, their uses and limitations with particular attention paid to the best validated and most comprehensive models, in addition to those models which have been utilized to investigate potential therapeutic interventions for the treatment or prevention of preeclampsia.

Incomplete spiral artery remodelling is the first of two stages of pre-eclampsia, typically of early onset. The second stage comprises dysregulated uteroplacental perfusion and placental oxidative stress. Oxidatively stressed syncytiotrophoblast (STB) over-secretes proteins that perturb maternal angiogenic balance and are considered to be pre-eclampsia biomarkers. We propose that, in addition and more fundamentally, these STB-derived proteins are biomarkers of a cellular (STB) stress response, which typically involves up-regulation of some proteins and down-regulation of others (positive and negative stress proteins respectively). Soluble vascular growth factor receptor-1 (sVEGFR-1) and reduced growth factor (PlGF) then exemplify positive and negative STB stress response proteins in the maternal circulation. Uncomplicated term pregnancy is associated with increasing sVEGFR-1 and decreasing PlGF, which can be interpreted as evidence of increasing STB stress. STB pathology, at or after term (for example focal STB necrosis) demonstrates this stress, with or without pre-eclampsia. We review the evidence that when placental growth reaches its limits at term, terminal villi become over-crowded with diminished intervillous pore size impeding intervillous perfusion with increasing intervillous hypoxia and STB stress. This type of STB stress has no antecedent pathology, so the fetuses are well-grown, as typifies late onset pre-eclampsia, and prediction is less effective than for the early onset syndrome because STB stress is a late event. In summary, abnormal placental perfusion and STB stress contribute to the pathogenesis of early and late onset pre-eclampsia. But the former has an extrinsic cause - poor placentation, whereas the latter has an intrinsic cause, 'microvillous overcrowding', as placental growth reaches its functional limits. This model explains important features of late pre-eclampsia and raises questions of how antecedent medical risk factors such as

Full Text Available Findings have shown that low serum 25-hydroxy vitamin D level is a possible risk factor for incidence of preeclampsia during pregnancy. Vitamin D has important effects on multiple biological pathways, including angiogenesis. Some studies have shown that vitamin D deficiency is highly prevalent among women suffering from preeclampsia, influencing immune modulation and vascular function. Evidence has shown that an imbalance of pro-antigenic and anti-angiogenic proteins can be considered as a possible etiological factor in the development of preeclampsia. Besides, there is a series of studies linking the renin–angiotensin aldosterone system (RAAS with preeclampsia. In this article, we review the current studies evaluating the association between maternal vitamin D status and vascular health, metabolism, placental immune function and the risk of preeclampsia. We provided evidence of the different factor involved in the metabolism of vitamin D and vitamin D receptor (VDR expression, gene regulations, immune function, and chronic disease when vitamin D is used optimally.

To clarify the alterations in serum adropin and preptin concentrations in preeclampsia, we determined serum adropin and preptin levels in 29 women with normal pregnancy and 32 women with preeclampsia. We found that maternal age, body mass index and fetal gender were not significantly different between two groups; however, blood pressure, gestational age and neonatal birth weight were significantly different. Serum adropin levels were significantly increased in women with preeclampsia compared with those with normal pregnancy but there were no significant differences in preptin levels. An increase in maternal serum adropin level was found in preeclampsia, and this may be a compensation for pregnancy complicated with preeclampsia.

Full Text Available Abstract    INTRODUCTION: Preeclampsia affects about 5-10% of all pregnancies and is a major cause of maternal, fetal and neonatal mortality and morbidity. The cardiovascular system undergoes a host of changes in association with development of preeclampsia. LDH is a useful biochemical marker that reflects the severity of the occurrence of preeclampsia.    METHOD AND MATERIALS: One hundred pregnant women were selected for this study, 50 normal pregnant women as controls and 50 preeclamptic women as the study group.  Cardiac enzymes (serum LDH, serum AST, serum CK and serum CKMB of these women were analyzed.    RESULTS: Mean Serum LDH and mean serum AST concentrations were significantly higher in preeclamptic patients compared to normal pregnant women (348.34 ± 59.17 vs. 255.92 ± 43.26, P < 0.01 and (34.32 ± 10.37 vs. 22.06 ± 5.10, P < 0.01 respectively.     CONCLUSION: LDH and AST may be increased due to liver damage. This endothelial vascular damage is the main cause in the occurrence of preeclampsia. Higher levels of LDH and AST are very useful markers to identify the occurrence of preeclampsia.      Keywords: LDH, Preeclampsia, AST, Cardiac Enzymes.

Preeclampsia complicates 2-8% of all pregnancies. Studies on the association of preeclampsia with thrombophilia are conflicting. Clinical heterogeneity of the disease may be one of the explanations. The present study addresses the question whether different phenotypes of preeclampsia are associated with thrombophilia factors. Study design We planned a retrospective cohort study. From 1985 until 2010 women with preeclampsia were offered postpartum screening for the following thrombophilia factors: anti-phospholipid antibodies, APC-resistance, protein C deficiency and protein S deficiency, hyperhomocysteineamia, factor V Leiden and Prothrombin gene mutation. Hospital records were used to obtain information on phenotypes of the preeclampsia and placental histology. We identified 844 women with singleton pregnancies who were screened for thrombophilia factors. HELLP complicated 49% of pregnancies; Fetal growth restriction complicated 61% of pregnancies. Early delivery (preeclampsia was associated with protein S deficiency (p=0.01). Fetal growth restriction was associated with anti-phospholipid antibodies (ppreeclampsia was associated with anti-phospholipid antibodies (p=0.01). Extensive placental infarction (>10%) was associated with anti-phospholipid antibodies (ppreeclampsia, especially if complicated by fetal growth restriction, are associated with anti-phospholipid antibodies. Other phenotypes of preeclampsia, especially HELLP syndrome, were not associated with thrombophilia. We advise only to test for anti-phospholipid antibodies after early onset preeclampsia, especially if complicated by fetal growth restriction. We suggest enough evidence is presented to justify no further studies are needed. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Andrea Brazdova

2014-10-01

Full Text Available Pre-eclampsia is a serious pathological state affecting 5-10% of pregnant women. Currently, it is diagnosed in the second half of pregnancy, particularly after the 20th week. Symptoms mostly correspond to the changes of blood vessels and kidneys. The severity of pre-eclampsia is proportional to symptomatic manifestations, thus the more symptoms present, the higher is of pre-eclampsia development. Although there are several studies dealing with pre-eclampsia pathology, the complete etiology is still unknown. In this review paper, several theories are presented and discussed.

Risk factors for preeclampsia are well established, whereas, the triggers associated with timing of preeclampsia onset are not. The aim of this study was to establish whether recent infection or other triggers were associated with timing of preeclampsia onset. We used a case-crossover design with preeclampsia cases serving as their own controls. Women with singleton pregnancies of ≥20 weeks gestation presenting at three hospitals were eligible for inclusion. Exposures to potential triggers were identified via guided questionnaire. Infective episodes included symptoms lasting >24 h. Preeclampsia was defined as hypertension (BP ≥140 mmHg and/or ≥90 mmHg) and proteinuria (protein/creatinine ratio ≥30 mg/mmol). Conditional logistic regression was used to compare the odds of exposure to potential triggers in the case windows (1-7 days preceding diagnosis of preeclampsia) and control windows (8-14 days prior to diagnosis); unadjusted odds ratios (ORs) are reported. Among 286 recruited women, 25 (8.7%) reported a new infection in the 7 days prior to preeclampsia onset and 21 (7.3%) in the 8-14 days prior. There was no significant association between onset of infection in the 7 days prior and preeclampsia diagnosis (OR 1.24, 95% CI 0.65, 2.34). Consumption of caffeine (OR 0.51, 95% CI 0.33, 0.77), spicy food (OR 0.49, 95% CI 0.30, 0.81), and alcohol (OR 0.26, 95% CI 0.10, 0.71) were strongly inversely associated with preeclampsia onset. Recent infection does not appear to trigger preeclampsia. Decreased consumption of caffeine, spicy food, and alcohol may be prodromal markers. Such behaviours may be early markers of imminent preeclampsia. © 2016 John Wiley & Sons Ltd.

Environmental noise exposure is associated with a greater risk of hypertension, but the link with preeclampsia, a hypertensive disorder of pregnancy, is unclear. We sought to determine the relationship between environmental noise pollution and risk of preeclampsia during pregnancy. We analyzed a population-based cohort comprising 269,263 deliveries on the island of Montreal, Canada between 2000 and 2013. We obtained total environmental noise pollution measurements (LA eq24 , L den , L night ) from land use regression models, and assigned noise levels to each woman based on the residential postal code. We computed odds ratios (OR) and 95% confidence intervals (CI) for the association of noise with preeclampsia in mixed logistic regression models with participants as a random effect, and adjusted for air pollution, neighbourhood walkability, maternal age, parity, multiple pregnancy, comorbidity, socioeconomic deprivation, and year of delivery. We assessed whether noise exposure was more strongly associated with severe or early onset preeclampsia than mild or late onset preeclampsia. Prevalence of preeclampsia was higher for women exposed to elevated environmental noise pollution levels (LA eq24h  ≥ 65 dB(A) = 37.9 per 1000 vs. <50 dB(A) = 27.9 per 1000). Compared with 50 dB(A), an LA eq24h of 65.0 dB(A) was not significantly associated the risk of preeclampsia (OR 1.09, 95% CI 0.99-1.20). Associations were however present with severe (OR 1.29, 95% CI 1.09-1.54) and early onset (OR 1.71, 95% CI 1.20-2.43) preeclampsia, with results consistent across all noise indicators. The associations were much weaker or absent for mild and late preeclampsia. Environmental noise pollution may be a novel risk factor for pregnancy-related hypertension, particularly more severe variants of preeclampsia. Copyright © 2018 Elsevier Ltd. All rights reserved.

Objectives Preeclampsia is divided into early-onset (delivery before 34 weeks of gestation) and late-onset (delivery at or after 34 weeks) subtypes, which may rise from different etiopathogenic backgrounds. Early-onset disease is associated with placental dysfunction. Late-onset disease develops predominantly due to metabolic disturbances, obesity, diabetes, lipid dysfunction, and inflammation, which affect endothelial function. Our aim was to use cluster analysis to investigate clinical factors predicting the onset and severity of preeclampsia in a cohort of women with known clinical risk factors. Methods We recruited 903 pregnant women with risk factors for preeclampsia at gestational weeks 12+0–13+6. Each individual outcome diagnosis was independently verified from medical records. We applied a Bayesian clustering algorithm to classify the study participants to clusters based on their particular risk factor combination. For each cluster, we computed the risk ratio of each disease outcome, relative to the risk in the general population. Results The risk of preeclampsia increased exponentially with respect to the number of risk factors. Our analysis revealed 25 number of clusters. Preeclampsia in a previous pregnancy (n = 138) increased the risk of preeclampsia 8.1 fold (95% confidence interval (CI) 5.7–11.2) compared to a general population of pregnant women. Having a small for gestational age infant (n = 57) in a previous pregnancy increased the risk of early-onset preeclampsia 17.5 fold (95%CI 2.1–60.5). Cluster of those two risk factors together (n = 21) increased the risk of severe preeclampsia to 23.8-fold (95%CI 5.1–60.6), intermediate onset (delivery between 34+0–36+6 weeks of gestation) to 25.1-fold (95%CI 3.1–79.9) and preterm preeclampsia (delivery before 37+0 weeks of gestation) to 16.4-fold (95%CI 2.0–52.4). Body mass index over 30 kg/m2 (n = 228) as a sole risk factor increased the risk of preeclampsia to 2.1-fold (95%CI 1.1–3

Preeclampsia is associated with profound vasoconstriction in most organ systems and reduced plasma volume. Because water immersion produces a marked central redistribution of blood volume and suppresses the renin-angiotensin system response and sympathetic activity, we hypothesized that water immersion might be useful in the treatment of preeclampsia. The effects of thermoneutral water immersion for 3 hours on central and peripheral hemodynamics were evaluated in 7 preeclamptic patients, 7 normal pregnant control patients, and 7 nonpregnant women. Finger plethysmography was used to determine hemodynamic measurements (cardiac output and total peripheral resistance), and forearm blood flow was measured by strain gauge plethysmography. Postischemic hyperemia was used to determine endothelium-dependent vasodilation. Analysis was by analysis of variance for repeated measurements. During water immersion cardiac output increased while diastolic blood pressure and heart rate decreased, although systolic blood pressure remained unchanged in each group. Forearm blood flow increased significantly in the normal pregnant and preeclamptic subjects. Total peripheral resistance decreased in all groups, but values in preeclamptic patients remained above those of normotensive pregnant women. Water immersion had no effect on endothelium-dependent vasodilation in the preeclamptic group, and most hemodynamic changes that were observed reversed to baseline within 2 hours of completion of the procedure. Although water immersion results in hemodynamic alterations in a manner that is theoretically therapeutic for women with preeclampsia, the effect was limited and short-lived. In addition water immersion had no effect on endothelium-dependent vasodilation in women with preeclampsia. The therapeutic potential for water immersion in preeclampsia appears to be limited.

Preeclampsia is a hypertensive disorder that complicates 3-7% of pregnancies. The development of preeclampsia has not been completely elucidated and current therapies are not broadly efficacious. The apelinergic system appears to be involved in hypertensive disorders and experimental studies indicate a role of this system in preeclampsia. Thus, an epidemiological evaluation of apelin protein concentration in plasma was conducted in case-control study of pregnant women. Data and maternal plasma samples were collected from pregnant women with confirmed preeclampsia (n = 76) or normotensive controls (n = 79). Concentrations of apelin peptides were blindly measured using enzyme-linked immunosorbent assay. Data were subjected to statistical analyses. Plasma apelin concentrations, measured at delivery, were lower in preeclampsia cases compared with controls (mean ± standard deviation: 0.66 ± 0.29 vs. 0.78 ± 0.31 ng/mL, p = 0.02). After controlling for confounding by maternal age, smoking status, and pre-pregnancy body mass index, odds of preeclampsia were 48% lower for women with high versus low plasma apelin (≥0.73 vs. preclampsia and other hypertensive maternal disorders.

BACKGROUND: In parous women preeclampsia has been associated with reduced risk of developing breast cancer. Characteristics of births following preeclamptic pregnancies may help understand mechanisms involved in the breast cancer risk reduction inferred by preeclampsia. METHODS: We conducted...... a register-based cohort study of all Danish women giving birth during 1978-2010 (n = 778,701). The association between preeclampsia and breast cancer was evaluated overall and according to birth characteristics by means of incidence rate ratios (IRR) estimated in Poisson regression models. RESULTS: Compared...... with women with non-preeclamptic pregnancies only, women with one or more preeclamptic pregnancies were 19% significantly less likely to develop breast cancer (IRR = 0.81 [95% CI 0.72-0.93]). We found some indication of greater risk reduction in women with term births, one or more previous births...

2014-10-01

Background: Preeclampsia contributes significantly to pregnancy-associated morbidity and mortality as well as future risk of cardiovascular disease in mother and offspring, and preeclampsia in offspring. The lack of reliable methods for early detection limits the opportunities for prevention, diagnosis, and timely treatment. Purpose: The purpose of this study was to explore distinct DNA methylation patterns associated with preeclampsia in both maternal cells and fetal-derived tissue that represent potential biomarkers to predict future preeclampsia and inheritance in children. Method: A convenience sample of nulliparous women (N = 55) in the first trimester of pregnancy was recruited for this prospective study. Genome-wide DNA methylation was quantified in first-trimester maternal peripheral white blood cells and placental chorionic tissue from normotensive women and those with preeclampsia (n = 6/group). Results: Late-onset preeclampsia developed in 12.7% of women. Significant differences in DNA methylation were identified in 207 individual linked cytosine and guanine (CpG) sites in maternal white blood cells collected in the first trimester (132 sites with gain and 75 sites with loss of methylation), which were common to approximately 75% of the differentially methylated CpG sites identified in chorionic tissue of fetal origin. Conclusion: This study is the first to identify maternal epigenetic targets and common targets in fetal-derived tissue that represent putative biomarkers for early detection and heritable risk of preeclampsia. Findings may pave the way for diagnosis of preeclampsia prior to its clinical presentation and acute damaging effects, and the potential for prevention of the detrimental long-term sequelae.

Preeclampsia, a disorder with prominent cardiovascular manifestations, is a cause of maternal, fetal, and infant morbidity and mortality. Chocolate contains compounds that may promote cardiovascular health. A recent study found chocolate consumption during pregnancy, and, particularly, increasing cord serum concentration of theobromine (the primary methylxanthine alkaloid in chocolate), to be associated with reduced occurrence of preeclampsia. We studied 2769 women who comprised the control group from a case-control study of caffeine metabolites and spontaneous abortion nested within the Collaborative Perinatal Project. These women were pregnant between 1959 and 1966, with liveborn infants of at least 28 weeks' gestation. Serum was drawn at 26 weeks' gestation, and assayed for theobromine by high-performance liquid chromatography. Odds ratios (ORs) for preeclampsia were estimated using logistic regression, and adjusted for age, education, prepregnant weight, race, parity, smoking, and gestation at blood draw. Preeclampsia occurred in 68 (2.9%) of 2105 eligible women. Adjusted ORs for preeclampsia were near unity across most third-trimester theobromine concentrations. Adjusted ORs for preeclampsia according to theobromine concentration in serum at theobromine and preeclampsia.

Endothelial dysfunction has been described as the final common pathophysiological pathway in the development of preeclampsia. Since it has been suggested that homocyst(e)ine damages endothelial cells, we measured serum homocyst(e)ine levels in women with preeclampsia and in healthy pregnant women in order to find a new prognostic parameter for women with preeclampsia. Forty-five women with preeclampsia and 45 healthy women with uncomplicated pregnancies, matched for age and parity, were entered into the study. Serum homocyst(e)ine levels were measured by gas chromatography-mass spectrometry analysis and correlated to clinical data. Logistic regression models were used to analyse the influence of serum homocyst(e)ine levels on the presence of preeclampsia versus healthy pregnant women and on the risk of premature termination of pregnancy due to preeclampsia. Median serum homocyst(e)ine levels in women with preeclampsia and healthy pregnant women were 14.2 (range 5.7-38.1) mumol/L and 15.1 (range 5.2-23.1) mumol/L, respectively (Mann-Whitney U-test, p = 0.8). In univariate logistic regression models, serum homocyst(e)ine levels had no significant influence on the odds of presenting with preeclampsia versus healthy pregnant women (univariate logistic regression model, p = 0.8) and on the odds of premature termination of pregnancy due to preeclampsia (univariate logistic regression model, p = 0.3). Serum homocyst(e)ine levels are not elevated in women with preeclampsia and are not associated with clinical outcome in women with preeclampsia.

Large epidemiologic studies support the role of dyslipidemia in preeclampsia; however, the etiology of preeclampsia or whether dyslipidemia plays a causal role remains unclear. We examined the association between the genetic predisposition to dyslipidemia and risk of preeclampsia using validated genetic markers of dyslipidemia. Preeclampsia cases (n = 164) and normotensive controls (n = 110) were selected from live birth certificates to nulliparous Iowa women during the period August 2002 to May 2005. Disease status was verified by medical chart review. Genetic predisposition to dyslipidemia was estimated by 4 genetic risk scores (GRS) (total cholesterol (TC), LDL cholesterol (LDL-C), HDL cholesterol (HDL-C), and triglycerides) on the basis of established loci for blood lipids. Logistic regression analyses were used to evaluate the relationships between each of the 4 genotype scores and preeclampsia. Replication analyses were performed in an independent, US population of preeclampsia cases (n = 516) and controls (n = 1,097) of European ancestry. The GRS related to higher levels of TC, LDL-C, and triglycerides demonstrated no association with the risk of preeclampsia in either the Iowa or replication population. The GRS related to lower HDL-C was marginally associated with an increased risk for preeclampsia (odds ratio (OR) = 1.03, 95% confidence interval (CI) = 0.99-1.07; P = 0.10). In the independent replication population, the association with the HDL-C GRS was also marginally significant (OR = 1.03, 95% CI: 1.00-1.06; P = 0.04). Our data suggest a potential effect between the genetic predisposition to dyslipidemic levels of HDL-C and an increased risk of preeclampsia, and, as such, suggest that dyslipidemia may be a component along the causal pathway to preeclampsia. © American Journal of Hypertension, Ltd 2014.

2011-07-01

Full Text Available Background: Preeclampsia is the most common and major medical complication of pregnancy with a high incidence of maternal and foetal morbidity and mortality. During pregnancy abnormally increased lipid peroxidation and free radical formation as well as significantly decreased antioxidants production in maternal blood may lead to pathogenesis of preeclampsia. So, we designed this study as little information is known about lipid peroxidation and antioxidant level in preeclampsia. Objectives: To assess the serum malondialdehyde (MDA level as a lipid peroxidation product and vitamin E (antioxidant level in women with preeclampsia as well as in normal pregnancy and to compare the values. Materials and Methods: The study was conducted on 60 women aged from 25 to 35 years in the department of Biochemistry, Budi Kemuliaan Maternity Hospital (BKMH in Jakarta during the period April to July 2004. Twenty were normal pregnant women and 20 were preeclamptic patients. For comparison age matched 20 apparently healthy nonpregnant women were included in the study. The study subjects were selected from outpatient department (OPD of Obstetrics and Gynaecology of BKMH in Jakarta. Serum MDA (lipid peroxidation product level was measured by thiobarbituric acid reactive substances assay (TBRAS method and vitamin E was estimated spectroflurometrically. Data were analyzed by unpaired Student’s t test between the groups by using SPSS version 12. Results: The mean serum MDA levels were significantly higher in normal pregnancy and also in preeclampsia than that of nonpregnant control group women (p<0.001. Again the serum MDA levels were significantly higher in preeclampsia than that of normal pregnant women (p<0.001. The serum vitamin E levels were significantly lower in preeclampsia and also in normal pregnancy than that of nonpregnant control women (p<0.001. Moreover, the serum vitamin E levels were significantly lower in preeclampsia compared to that of normal

Hee Jin Park

2015-08-01

Full Text Available Although the precise pathophysiology of pre-eclampsia remains unknown, this condition continues to be a major cause of maternal and fetal mortality. Early prediction of pre-eclampsia would allow for timely initiation of preventive therapy. A combination of biophysical and biochemical markers are superior to other tests for early prediction of the development of pre-eclampsia. Apart from the use of parameters in first-trimester aneuploidy screening, cell-free fetal DNA quantification is emerging as a promising marker for prediction of pre-eclampsia. This article reviews the current research of the most important strategies for prediction of pre-eclampsia, including the use of maternal risk factors, mean maternal arterial pressure, ultrasound parameters, and biomarkers.

Serum lipid levels in pregnancies complicated by preeclampsia

Directory of Open Access Journals (Sweden)

Valmir Jose de Lima

Full Text Available CONTEXT AND OBJECTIVE: Pre-eclampsia is a disorder that occurs only during pregnancy. Postpartum changes relating to lipid metabolism may contribute towards the endothelial lesions observed in preeclampsia. Thus, the aim of the present study was to evaluate the lipid profile among patients who present preeclampsia and correlate these parameters with 24-hour proteinuria. DESIGN AND SETTING: Cross-sectional analytical study including 77 pregnant patients seen at Hospital Dório Silva. METHODS: This study involved 42 women with preeclampsia and 35 healthy pregnant women in the third trimester of pregnancy as controls. Blood samples were obtained from all the patients, and the serum levels of triglycerides, total cholesterol, low-density lipoproteins (LDL, high-density lipoproteins (HDL and very low density lipoproteins (VLDL were determined. Cases and controls were matched for maternal age, gestational week and body mass index. RESULTS: The VLDL and triglyceride values from the women with preeclampsia were significantly higher than those of the healthy women. There was a positive correlation between increased proteinuria and higher VLDL and triglyceride levels in patients with preeclampsia. CONCLUSION: Among the patients with preeclampsia, higher VLDL and triglyceride levels were positively correlated with proteinuria. These observations indicate that the pregnant women who presented elevated lipid levels were more susceptible to cardiovascular disorders and, consequently, pre-eclampsia.

MONOCYTES AND MACROPHAGES IN PREGNANCY AND PREECLAMPSIA

Full Text Available Preeclampsia is an important complication in pregnancy, characterized byhypertension and proteinuria in the second half of pregnancy. Generalizedactivation of the inflammatory response is thought to play a role in thepathogenesis of preeclampsia. Monocytes may play a central role in thisinflammatory response. Monocytes are short lived cells, that mature in thecirculation and invade into tissues upon an inflammatory stimulus anddevelop into macrophages. Macrophages are abundantly present in theendometrium and play a role in implantation and placentation in normalpregnancy. In preeclampsia, these macrophages appear to be present in largernumbers and are also activated. In the present review we focused on the roleof monocytes and macrophages in the pathophysiology of preeclampsia.

Although the exact pathophysiology of preeclampsia is not completely understood, the utility of different platelets indices can be utilized to predict preeclampsia. To compare platelet indices, namely platelet count (PC), mean platelet volume (MPV), platelet distribution width (PDW), and PC to MPV ratio in women with preeclampsia compared with healthy controls. Qassim Hospital, Kingdom of Saudi Arabia. A case-control study. Sixty preeclamptic women were the cases and an equal number of healthy pregnant women were the controls. There was no significant difference in age, parity, and body mass index between the study groups. Sixteen and 44 of the cases were severe and mild preeclampsia, respectively. There was no significant difference in PDW and MPV between the preeclamptic and control women. Both PC and PC to MPV ratios were significantly lower in the women with preeclampsia compared with the controls. There was no significant difference in the PC, PDW, MPV, and PC to MPV ratio when women with mild and severe preeclampsia were compared. Using receiver operating characteristic (ROC) curves, the PC cutoff was 248.0×10 3 /µL for diagnosis of pre-eclampsia ( P =0.019; the area under the ROC curve was 62.4%). Binary regression suggests that women with PC preeclampsia (odds ratio =2.2, 95% confidence interval =1.08-4.6, P =0.03). The PC/MPV cutoff was 31.2 for diagnosis of preeclampsia ( P =0.035, the area under the ROC curve was 62.2%). PC preeclampsia.

2013-07-01

Full Text Available Background and Aim: Preeclampsia is a considerable problem of pregnancy. Endothelial dysfunction and placental hypoxia are the current hypothesis of preeclampsia. Chronic inflammation, including periodontitis may provoke systemic maternal and placental pro-inflammatory endothelial dysfunction, which represent a significant risk factor for diseases of vascular origin. So this study was carried out to evaluate the possible relationship between periodontitis and preeclampsia. Methods: A total of 360 pregnant women were included, corresponding to 180 pregnant women with mild or sever periodotitis in one group and 180 pregnant women with periodontal health in the other group. Periodontitis was determined by the sum of all pockets with pocket probing depth (PPD ≥4mm and bleeding on probing. periodontal health was defined as the absence of PPD≥ 4mm. Then two groups evaluated to determine the presence of preeclampsia. After delivery, Child weight at birth and gestational age was also evaluated. Chi square and t test analysis were used to analyze the data. Results: There was statistically significant difference between two groups in presence of preeclampsia (p=0.003. Women who had a worse periodontal condition were at higher risk for preeclampsia. In addition, birth weight and gestational age was statistically lower in the case group than the control group (p < 0.001. Conclusion: The results indicate that the presence and severity of peridontitis increase the risk for occurrence of preeclampsia and adverse pregnancy outcomes.

Naljayan, Mihran V.; Karumanchi, S. Ananth

2013-01-01

Preeclampsia affecting 3-5% of all pregnancies is a major cause of maternal and perinatal morbidity and mortality worldwide. This disorder is characterized by a constellation of signs and symptoms, most notably new onset hypertension and proteinuria during the last trimester of pregnancy. In this review, the molecular mechanisms of preeclampsia with an emphasis on the role of circulating anti-angiogenic proteins in the pathogenesis of preeclampsia and its complications will be discussed.

Low-Dose Aspirin for the Prevention of Preeclampsia.

Preeclampsia is a hypertensive disorder specific to pregnancy that remains a significant cause of maternal and neonatal morbidity and mortality. Identification of women who are most at risk for preeclampsia is imprecise. Because of the potential negative health consequences of preeclampsia for women and newborns and the lack of effective screening mechanisms preventing preeclampsia is an important component of prenatal care. Researchers have documented that low-dose aspirin, taken daily after the first trimester, can decrease the development of preeclampsia and reduce the incidence of preterm birth and birth of small-for-gestational-age infants. This column includes an overview of low-dose aspirin in pregnancy and a review of current recommendations from leading national organizations. © 2018 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

Low vitamin D status in pregnancy was proposed as a risk factor of preeclampsia. We assessed the effect of vitamin D supplementation (4,400 vs. 400 IU/day), initiated early in pregnancy (10-18 weeks), on the development of preeclampsia. The effects of serum vitamin D (25-hydroxyvitamin D [25OHD]) levels on preeclampsia incidence at trial entry and in the third trimester (32-38 weeks) were studied. We also conducted a nested case-control study of 157 women to investigate peripheral blood vitamin D-associated gene expression profiles at 10 to 18 weeks in 47 participants who developed preeclampsia. Of 881 women randomized, outcome data were available for 816, with 67 (8.2%) developing preeclampsia. There was no significant difference between treatment (N = 408) or control (N = 408) groups in the incidence of preeclampsia (8.08% vs. 8.33%, respectively; relative risk: 0.97; 95% CI, 0.61-1.53). However, in a cohort analysis and after adjustment for confounders, a significant effect of sufficient vitamin D status (25OHD ≥30 ng/ml) was observed in both early and late pregnancy compared with insufficient levels (25OHD preeclampsia (FDR preeclampsia incidence in the intention-to-treat paradigm. However, vitamin D levels of 30 ng/ml or higher at trial entry and in late pregnancy were associated with a lower risk of preeclampsia. Differentially expressed vitamin D-associated transcriptomes implicated the emergence of an early pregnancy, distinctive immune response in women who went on to develop preeclampsia.

Preeclampsia is a pregnancy-specific syndrome characterized by placental dysfunction and an angiogenic imbalance. Systemically, levels of thrombomodulin, an endothelium- and syncytiotrophoblast-bound protein that regulates coagulation, inflammation, apoptosis, and tissue remodeling, are increased. We aimed to investigate placental thrombomodulin dysregulation and consequent downstream effects in the pathogenesis of preeclampsia. Placentas from 28 preeclampsia pregnancies, 30 uncomplicated pregnancies, and 21 pregnancies complicated by growth restriction as extra controls were included. Immunohistochemical staining of thrombomodulin, caspase-3, and fibrin was performed. Placental mRNA expression of thrombomodulin, inflammatory markers, matrix metalloproteinases 2 and 9, and soluble Flt-1 were measured with quantitative polymerase chain reaction. Thrombomodulin mRNA expression was determined in vascular endothelial growth factor-transfected trophoblast cell lines. Thrombomodulin protein and mRNA expression were decreased in preeclampsia as compared with both control groups (P=0.001). Thrombomodulin mRNA expression correlated with maternal body mass index (Ppreeclampsia. An increase in placental apoptotic cells was associated with preeclampsia (Ppreeclampsia, but not with fibrin deposits or inflammatory markers. Placental soluble Flt-1 expression correlated with decreased thrombomodulin expression. Vascular endothelial growth factor induced upregulation of thrombomodulin expression in trophoblast cells. Decreased thrombomodulin expression in preeclampsia may play a role in placental dysfunction in preeclampsia and is possibly caused by an angiogenic imbalance. Hypertension and obesity are associated with thrombomodulin downregulation. These results set the stage for further basic and clinical research on thrombomodulin in the pathogenesis of preeclampsia and other syndromes characterized by endothelial dysfunction. © 2016 American Heart Association, Inc.

Haptoglobin phenotype, preeclampsia risk and the efficacy of vitamin C and E supplementation to prevent preeclampsia in a racially diverse population.

Full Text Available Haptoglobin's (Hp antioxidant and pro-angiogenic properties differ between the 1-1, 2-1, and 2-2 phenotypes. Hp phenotype affects cardiovascular disease risk and treatment response to antioxidant vitamins in some non-pregnant populations. We previously demonstrated that preeclampsia risk was doubled in white Hp 2-1 women, compared to Hp 1-1 women. Our objectives were to determine whether we could reproduce this finding in a larger cohort, and to determine whether Hp phenotype influences lack of efficacy of antioxidant vitamins in preventing preeclampsia and serious complications of pregnancy-associated hypertension (PAH. This is a secondary analysis of a randomized controlled trial in which 10,154 low-risk women received daily vitamin C and E, or placebo, from 9-16 weeks gestation until delivery. Hp phenotype was determined in the study prediction cohort (n = 2,393 and a case-control cohort (703 cases, 1,406 controls. The primary outcome was severe PAH, or mild or severe PAH with elevated liver enzymes, elevated serum creatinine, thrombocytopenia, eclampsia, fetal growth restriction, medically indicated preterm birth or perinatal death. Preeclampsia was a secondary outcome. Odds ratios were estimated by logistic regression. Sampling weights were used to reduce bias from an overrepresentation of women with preeclampsia or the primary outcome. There was no relationship between Hp phenotype and the primary outcome or preeclampsia in Hispanic, white/other or black women. Vitamin supplementation did not reduce the risk of the primary outcome or preeclampsia in women of any phenotype. Supplementation increased preeclampsia risk (odds ratio 3.30; 95% confidence interval 1.61-6.82, p<0.01 in Hispanic Hp 2-2 women. Hp phenotype does not influence preeclampsia risk, or identify a subset of women who may benefit from vitamin C and E supplementation to prevent preeclampsia.

Why preeclampsia still exists?

Preeclampsia (PE) is a deadly gestational disease affecting up to 10% of women and specific of the human species. Preeclampsia is clearly multifactorial, but the existence of a genetic basis for this disease is now clearly established by the existence of familial cases, epidemiological studies and known predisposing gene polymorphisms. PE is very common despite the fact that Darwinian pressure should have rapidly eliminated or strongly minimized the frequency of predisposing alleles. Consecutive pregnancies with the same partner decrease the risk and severity of PE. Here, we show that, due to this peculiar feature, preeclampsia predisposing-alleles can be differentially maintained according to the familial structure. Thus, we suggest that an optimal frequency of PE-predisposing alleles in human populations can be achieved as a result of a trade-off between benefits of exogamy, importance for maintaining genetic diversity and increase of the fitness owing to a stable paternal investment.

BACKGROUND: Endometrial cancer is mainly dependent on oestrogen exposure. Preeclampsia has shown to reduce oestrogen levels hence preeclampsia may affect later endometrial cancer risk. METHODS: We conducted a case-control study of 523 Danish women with endometrial cancer and 52 299controls during...... 1978-2010. The association between preeclampsia and later endometrial cancer was evaluated overall and according to preeclampsia onset and type of endometrial cancer in conditional logistic regression models. RESULTS: We observed no overall association between preeclampsia and endometrial cancer risk...... (OR=1.11 (95% CI 0.68-1.81)). This was true for all endometrial cancer subtypes. In an analysis of preeclampsia onset, however, we report a markedly increased risk of endometrial cancer following early-onset preeclampsia (OR=2.64 (95% CI 1.29-5.38)). CONCLUSIONS: Although we report no obvious...

Introducción. Cada vez son más los hallazgos sobre la relación entre las concentraciones de vitamina D en el ser humano y diversas condiciones clínicas. Hay una gran cantidad de estudios que informan sobre dicha asociación, especialmente con complicaciones obstétricas, incluidas la preeclampsia y la diabetes mellitus de la gestación, entre otras, pero sus resultados todavía no son definitivos, por lo que se requieren estudios de intervención de calidad que confirmen la relación de la vitamina D con dichos resultados.Objetivo. Revisar la información plasmada en estudios en torno al papel de la vitamina D materna y el desarrollo de la preeclampsia.Materiales y métodos. La metodología usada siguió las recomendaciones de la guía Cochrane para la elaboración de revisiones sistemáticas y de la guía del grupo Meta-analysis of Observational Studies in Epidemiology (MOOSE) para los metaanálisis. La búsqueda incluyó estudios observacionales y ensayos clínicos controlados.Resultados. Los niveles bajos de vitamina D, medida con el examen de 25-hidroxivitamina D, son comunes en el embarazo. Los resultados de esta revisión sistemática y del metaanálisis sugieren una asociación inversa entre los niveles de vitamina D y el desarrollo de preeclampsia. Hubo heterogeneidad en los estudios en cuanto a su diseño, población y ubicación geográfica, así como a las definiciones de exposición y resultado. Los ensayos clínicos controlados aleatorizados se excluyeron del metaanálisis.Conclusión. Se encontró una asociación inversa que sugiere que, a mayores concentraciones de vitamina D, menor es la probabilidad de desarrollar preclampsia, a pesar de la heterogeneidad de la medida global en este tipo de análisis.

Preeclampsia is becoming an increasingly common diagnosis in the developed world and remains a high cause of maternal and fetal morbidity and mortality in the developing world. Delay in childbearing in the developed world feeds into the risk factors associated with preeclampsia, which include older maternal age, obesity, and/or vascular diseases. Inadequate prenatal care partially explains the persistent high prevalence in the developing world. In this review, we begin by presenting the most recent concepts in the pathogenesis of preeclampsia. Upstream triggers of the well described angiogenic pathways, such as the heme oxygenase and hydrogen sulfide pathways, as well as the roles of autoantibodies, misfolded proteins, nitric oxide, and oxidative stress will be described. We also detail updated definitions, classification schema, and treatment targets of hypertensive disorders of pregnancy put forth by obstetric and hypertensive societies throughout the world. The shift has been made to view preeclampsia as a systemic disease with widespread endothelial damage and the potential to affect future cardiovascular diseases rather than a self-limited occurrence. At the very least, we now know that preeclampsia does not end with delivery of the placenta. We conclude by summarizing the latest strategies for prevention and treatment of preeclampsia. A better understanding of this entity will help in the care of at-risk women before delivery and for decades after. Copyright © 2016 by the American Society of Nephrology.

Metabolites were then quantified and compared between groups.Urine and serum samples revealed clear differences between women with preeclampsia and both control groups (normal pregnant and non-pregnant women. Nine urine metabolites were significantly different between preeclampsia and the normal pregnant group. Urine samples from women with early onset preeclampsia clustered together in the multivariate analysis. The preeclampsia serum spectra showed higher levels of low and very-low density lipoproteins and lower levels of high-density lipoproteins when compared to both non-pregnant and normal pregnant women.The MR determined metabolic profiles in urine and serum from women with preeclampsia are clearly different from normal pregnant women. The observed differences represent a potential to examine mechanisms underlying different preeclampsia phenotypes in urine and serum samples in larger studies. In addition, similarities between preeclampsia and cardiovascular disease in metabolomics are demonstrated.

Immunology and Genetic of Preeclampsia

Full Text Available Preeclampsia is a disease characterized by hypertension and proteinuria in the third trimester of pregnancy. Preeclampsia is a major cause of maternal mortality, and fetal death, especially in developing countries, but its aetiology remains unclear. Key findings support a causal role of superficial placentation driven by immune mal maladaptation, which then lead to reduced concentrations of angiogenic growth factors and to an increase in placental debris in the maternal circulation resulting in a maternal inflammatory response. Epidemiological research has consistently demonstrated a substantial familial predisposition to preeclampsia. Unfortunately, the conquest of the genes explaining such a individual susceptibility has been proved to be a hard task. However, genetics will also inform us about causality of environmental factors, and then serve as a tool to prioritize therapeutic targets for preventive strategies.

11β-Hydroxysteroid Dehydrogenase 2 in Preeclampsia

Directory of Open Access Journals (Sweden)

Katarzyna Kosicka

2016-01-01

Full Text Available Preeclampsia is a serious medical problem affecting the mother and her child and influences their health not only during the pregnancy, but also many years after. Although preeclampsia is a subject of many research projects, the etiology of the condition remains unclear. One of the hypotheses related to the etiology of preeclampsia is the deficiency in placental 11β-hydroxysteroid dehydrogenase 2 (11β-HSD2, the enzyme which in normal pregnancy protects the fetus from the excess of maternal cortisol. The reduced activity of the enzyme was observed in placentas from pregnancies complicated with preeclampsia. That suggests the overexposure of the developing child to maternal cortisol, which in high levels exerts proapoptotic effects and reduces fetal growth. The fetal growth restriction due to the diminished placental 11β-HSD2 function may be supported by the fact that preeclampsia is often accompanied with fetal hypotrophy. The causes of the reduced function of 11β-HSD2 in placental tissue are still discussed. This paper summarizes the phenomena that may affect the activity of the enzyme at various steps on the way from the gene to the protein.

Objective. To investigate the efficacy of antioxidants for preventing preeclampsia and other maternal and fetal complications among pregnant women with low, moderate, or high risk of preeclampsia. Methods. We searched MEDLINE, Embase, CENTRAL, mRCT, and other databases, with no language or publication restrictions. Two independent reviewers selected randomized controlled trials that evaluated the use of antioxidants versus placebo and extracted the relevant data. Relative risks (RRs) and 95% confidence intervals (95% CIs) were calculated. The data were compiled through the random effects model. Main Results. Fifteen studies were included (21,012 women and 21,647 fetuses). No statistically significant difference was found between women who received antioxidant treatment and women who received placebo for preeclampsia (RR  = 0.92; 95% CI: 0.82–1.04), severe preeclampsia (RR  = 1.03; 95% CI: 0.87–1.22), preterm birth (RR  = 1.03; 95% CI: 0.94–1.14), and small for gestational age antioxidants group compared to placebo, but without significant statistical difference (RR  = 1.24; 95% CI: 0.85–1.80). Conclusions. The available evidence reviewed does not support the use of antioxidants during pregnancy for the prevention of preeclampsia and other outcomes. PMID:22593668

Preeclampsia is characterized by an increase in high blood pressure and decrease in GFR and proteinuria, however, the underlying mechanisms are still unclear. Renalase is a recently discovered protein implicated in regulation of blood pressure in humans. Plasma concentrations of serum renalase were measured in healthy controls, healthy pregnant and pregnant with preeclampsia matched for age, gestational age, in the third trimester of pregnancy. Serum renalase levels were compared in pregnant with and without preeclampsia and non-pregnant controls. Factors associated with serum renalase levels in pregnancies were also evaluated. In healthy pregnant serum renalase levels were significantly higher than in controls. However, pregnant with preeclampsia had lower renalase levels than healthy controls. Serum renalase levels were inversely associated with blood pressure levels and positively correlated with glomerular filtration rate. The results indicated that the development of preeclampsia in pregnant is accompanied by altered serum renalase levels. High blood pressure and kidney damage that characterize this disorder are mediated at least in part by low renalase levels.

Evidence-Based Revised View of the Pathophysiology of Preeclampsia.

Preeclampsia is a life-threatening vascular disorder of pregnancy due to a failing stressed placenta. Millions of women risk death to give birth each year and globally each year, almost 300,000 lose their life in this process and over 500,000 babies die as a consequence of preeclampsia. Despite decades of research, we lack pharmacological agents to treat it. Maternal endothelial oxidative stress is a central phenomenon responsible for the preeclampsia phenotype of high maternal blood pressure and proteinuria. In 1997, it was proposed that preeclampsia arises due to the loss of VEGF activity, possibly due to elevation in anti-angiogenic factor, soluble Flt-1 (sFlt-1). Researchers showed that high sFlt-1 and soluble endoglin (sEng) elicit the severe preeclampsia phenotype in pregnant rodents. We demonstrated that heme oxygenase-1 (HO-1)/carbon monoxide (CO) pathway prevents placental stress and suppresses sFlt-1 and sEng release. Likewise, hydrogen sulphide (H 2 S)/cystathionine-γ-lyase (Cth) systems limit sFlt-1 and sEng and protect against the preeclampsia phenotype in mice. Importantly, H 2 S restores placental vasculature, and in doing so improves lagging fetal growth. These molecules act as the inhibitor systems in pregnancy and when they fail, preeclampsia is triggered. In this review, we discuss what are the hypotheses and models for the pathophysiology of preeclampsia on the basis of Bradford Hill causation criteria for disease causation and how further in vivo experimentation is needed to establish 'proof of principle'. Hypotheses that fail to meet the Bradford Hill causation criteria include abnormal spiral artery remodelling and inflammation and should be considered associated or consequential to the disorder. In contrast, the protection against cellular stress hypothesis that states that the protective pathways mitigate cellular stress by limiting elevation of anti-angiogenic factors or oxidative stress and the subsequent clinical signs of preeclampsia

Preeclampsia reflects an unusual increase in systemic inflammation during pregnancy. We studied associations between preeclampsia and asthma, allergy, and eczema in Copenhagen Prospective Studies on Asthma in Childhood 2000 (COPSAC 2000 ) and in national registries. COPSAC 2000 is a high-risk birth cohort of 411 Danish children. Asthma, allergy, and eczema were diagnosed prospectively, and lung function measured at age 1 month and 7 years. Sensitization was evaluated at age 6 months, 18 months, 4 years, and 6 years by skin prick tests and IgE measurements. The register-based cohort included 1.7 million children from Danish national registries in the 35-year period 1977-2012. Children born to mothers with preeclampsia were analyzed regarding risk of asthma, allergy, and eczema. In the COPSAC 2000 cohort, 5.6% (n = 23) were diagnosed with preeclampsia. Preeclampsia was associated with increased risk of treatment with inhaled corticosteroids at age 7 years (adjusted odds ratio, 4.01 [95% confidence interval (CI), 1.11-14.43]; P = 0.0337), increased bronchial responsiveness to methacholine (adjusted β-coefficient log-μmol, -0.80 [95% CI, -1.55 to -0.06]; P = 0.0348), and allergic rhinitis (adjusted odds ratio, 4.83 [95% CI, 1.58-14.78]; P = 0.0057) in the 7-year-old children. Furthermore, the children had an increased risk of sensitization to both aeroallergens and food allergens, and increased amount of total IgE during childhood. In the registry-based cohort, 3.7% (n = 62,728) were born to mothers with preeclampsia. Preeclampsia was associated with increased risk of asthma, eczema, and aeroallergen and food allergy, especially pronounced after a duration of preeclampsia of 14 days or more. Maternal asthma increased the risk of preeclampsia. Preeclampsia is a shared prenatal risk factor for asthma, eczema, and allergy in childhood pointing toward in utero immune programming of the child.

This review evaluates the possible relationship between periodontal disease and pre-eclampsia, a major pregnancy complication. A generalized inflammatory response plays an important role in the pathogenesis of pre-eclampsia. Because periodontal disease is a low-grade inflammatory state, periodontal disease might contribute to the pathogenesis of pre-eclampsia. A literature search of PubMed, EMBASE and CINAHL until August 2010 revealed 12 eligible observational studies and three randomized-controlled trials (RCTs). It appeared difficult to compare these studies, due to variations in definitions of periodontal disease and pre-eclampsia, timing of periodontal examination and inadequate control for confounding factors. Eight observational studies reported a positive association, while four studies found no association. None of the RTCs reported reductions in pre-eclamptic rate after periodontal therapy during pregnancy. Therefore, it is questionable whether periodontal disease plays a causal role in the pathogenesis of pre-eclampsia. The observed association in eight observational studies might be the result of induction of periodontal disease due to the pre-eclamptic state or it may be an epiphenomenon of an exaggerated inflammatory response to pregnancy. Larger RCTs with pre-eclampsia as the primary outcome and pathophysiological studies are required to explore causality and to dissect biological mechanisms involved. © 2010 John Wiley & Sons A/S.

Objective: To determine the frequency and factors leading to recurrent preeclampsia. Methods: The cross-sectional study was conducted at the Jinnah Post Graduate Medical Centre, Karachi, from January 2011 to February 2012, and comprised parous subjects <40 years of age with history of preeclampsia in previous pregnancy/pregnancies with singleton pregnancy and gestational age of >20 weeks. Gestational age was determined by early scan with preeclampsia in index pregnancy. Data was collected through a specialised questionnaire and analysed using SPSS 16. Results: Of the 479 patients seen with preeclampsia, 121(25.26 percent) were of recurrent preeclampsia. The mean age of such patients was 29.7±4.9 years (range: 20-39 years). Further, 84(69.42 percent) patients were multipara and 40(33.05 percent) were grand multipara. Mean body mass index was 29.97±6.2 (range: 18-54). Besides, 28(23.14 percent) patients had gestational diabetes; 7(5.78 percent) were known diabetics; 24(19.83 percent) had chronic hypertension; 2(1.7 percent) patients had chronic renal disease; and 1(0.8 percent) had connective tissue disorder. Conclusion: Being over-weight, having gestational diabetes and chronic hypertension were main risk factors leading to recurrent preeclampsia. (author)

Preeclampsia is a prevalent hypertensive disorder of pregnancy and a leading cause of maternal and neonatal morbidity and mortality worldwide. This pathogenic condition is speculated to be caused by placental abnormalities that contribute to the maternal syndrome. However, the specific factors and signaling pathways that lead to impaired placentas and maternal disease development remain elusive. Using 2 independent animal models of preeclampsia (genetically engineered pregnant mice with elevated adenosine exclusively in placentas and a pathogenic autoantibody-induced preeclampsia mouse model), we demonstrated that chronically elevated placental adenosine was sufficient to induce hallmark features of preeclampsia, including hypertension, proteinuria, small fetuses, and impaired placental vasculature. Genetic and pharmacological approaches revealed that elevated placental adenosine coupled with excessive A₂B adenosine receptor (ADORA2B) signaling contributed to the development of these features of preeclampsia. Mechanistically, we provided both human and mouse evidence that elevated placental CD73 is a key enzyme causing increased placental adenosine, thereby contributing to preeclampsia. We determined that elevated placental adenosine signaling is a previously unrecognized pathogenic factor for preeclampsia. Moreover, our findings revealed the molecular basis underlying the elevation of placental adenosine and the detrimental role of excess placental adenosine in the pathophysiology of preeclampsia, and thereby, we highlight novel therapeutic targets. © 2014 American Heart Association, Inc.

Preeclampsia is a major pregnancy complication without curative treatment available. A Norwegian Preeclampsia Family Cohort was established to provide a new resource for genetic and molecular studies aiming to improve the understanding of the complex pathophysiology of preeclampsia. Participants were recruited from five Norwegian hospitals after diagnoses of preeclampsia registered in the Medical birth registry of Norway were verified according to the study's inclusion criteria. Detailed obstetric information and information on personal and family disease history focusing on cardiovascular health was collected. At attendance anthropometric measurements were registered and blood samples were drawn. The software package SPSS 19.0 for Windows was used to compute descriptive statistics such as mean and SD. P-values were computed based on t-test statistics for normally distributed variables. Nonparametrical methods (chi square) were used for categorical variables. A cohort consisting of 496 participants (355 females and 141 males) representing 137 families with increased occurrence of preeclampsia has been established, and blood samples are available for 477 participants. Descriptive analyses showed that about 60% of the index women's pregnancies with birth data registered were preeclamptic according to modern diagnosis criteria. We also found that about 41% of the index women experienced more than one preeclamptic pregnancy. In addition, the descriptive analyses confirmed that preeclamptic pregnancies are more often accompanied with delivery complications. The data and biological samples collected in this Norwegian Preeclampsia Family Cohort will provide an important basis for future research. Identification of preeclampsia susceptibility genes and new biomarkers may contribute to more efficient strategies to identify mothers "at risk" and contribute to development of novel preventative therapies.

Preeclampsia is a common pregnancy specific disease, that presents with hypertension and a variety of organ failures, including malfunction of kidneys, liver and lungs. At present, the only definitive treatment of preeclampsia is end the pregnancy and deliver the neonate and placenta. For women with mild preeclampsia in the preterm phase of pregnancy, expectant management is generally indicated to improve fetal maturity, often requiring maternal medical treatment. Last decades, more evidence is available that the underlying mechanism of preeclampsia, endothelial disease, is not limited to pregnancy but increases cardiovascular risk in later life. In this review, we present the most recent insight in preeclampsia with focus on impact on the fetus, short and long-term outcome of offspring's, and long-term outcome of women with a history of preeclampsia.

The etiology of preeclampsia is unknown. Tall women have been found to have lower incidence of preeclampsia. This points to a possible biological causal effect but may be because of socioeconomic confounding. We used paternal height as an unexposed control to examine confounding. The MoBa (Norwegian Mother and Child Cohort Study) was used to extract data on parental heights, maternal prepregnancy weight, other background factors, and pregnancy outcomes for 99 968 singleton births. Multiple logistic regression was used to estimate odds ratios for preeclampsia according to parental height. The adjusted odds ratio for preeclampsia was 0.74 (95% CI, 0.66-0.82) for women >172 cm as compared with women 186 cm was 1.03 (95% CI, 0.93-1.15) compared with men <178 cm. The association between maternal height and preeclampsia is unlikely to be because of confounding by familial, socioeconomic factors or by fetal genes related to height. The observed association between maternal height and preeclampsia merits further investigation. © 2018 American Heart Association, Inc.

Preeclampsia presents serious risk of both maternal and fetal morbidity and mortality. Biomarkers for the detection of preeclampsia are critical for risk assessment and targeted intervention. The goal of this study is to screen potential biomarkers for the diagnosis of preeclampsia and to illuminate the pathogenesis of preeclampsia development based on the differential expression network. Two groups of subjects, including healthy pregnant women, subjects with preeclampsia, were recruited for this study. The metabolic profiles of all of the subjects' serum were obtained by liquid chromatography quadruple time-of-flight mass spectrometry. Correlation between metabolites was analyzed by bioinformatics technique. Results showed that the PC(14:0/00), proline betaine and proline were potential sensitive and specific biomarkers for preeclampsia diagnosis and prognosis. Perturbation of corresponding biological pathways, such as iNOS signaling, nitric oxide signaling in the cardiovascular system, mitochondrial dysfunction were responsible for the pathogenesis of preeclampsia. This study indicated that the metabolic profiling had a good clinical significance in the diagnosis of preeclampsia as well as in the study of its pathogenesis. Copyright © 2017 Elsevier Inc.

Rayer, description of proteinuria in eclampsia, 2) 1897 Vaquez, discovery of gestational hypertension in eclamptic women, 3) In the 1970's, description of the "double" trophoblastic invasion existing only in humans (Brosens & Pijnenborg,), 4) between the 1970's and the 1990's, description of preeclampsia being a couple disease. The "paternity problem" (and therefore irruption of immunology), 5) at the end of the 1980's, a major step forward: Preeclampsia being a global endothelial cell disease (glomeruloendotheliosis, hepatic or cerebral endotheliosis, HELLP, eclampsia), inflammation (J.Roberts.C Redman, R Taylor), 6) End of the 1990's: Consensus for a distinction between early onset preeclampsia EOP and late onset LOP (34 weeks gestation), EOP being rather a problem of implantation of the trophoblast (and the placenta), LOP being rather a pre-existing maternal problem (obesity, diabetes, coagulopathies etc…). LOP is predominant everywhere on this planet, but enormously predominant in developed countries: 90% of cases. This feature is very different in countries where women have their first child very young (88% of world births), where the fatal EOP (early onset) occurs in more than 30% of cases. 7) What could be the common factor which could explain the maternal global endotheliosis in EOP and LOP?

Preeclampsia may present at any gestation but is more commonly encountered in the third trimester. Multiple risk factors have been documented, including: family history, nulliparity, egg donation, diabetes, and obesity. Significant progress has been made in developing tests to predict risk of preeclampsia in pregnancy, but these remain confined to clinical trial settings and center around measuring angiogenic profiles, including placental growth factor or newer tests involving metabolomics. Less progress has been made in developing new treatments and therapeutic targets, and aspirin remains one of the few agents shown to consistently reduce the risk of developing preeclampsia. This review serves to discuss recent advances in risk factor identification, prediction techniques, and management of preeclampsia in antenatal, intrapartum, and postnatal patients.

To determine if mid-pregnancy circulating immune biomarkers are associated with preeclampsia. Nested case-control study of 410 preeclamptic women and 297 normotensive controls with primiparous singleton pregnancies enrolled in the Danish National Birth Cohort. The mean gestational age in our cohort is 16 weeks (range 9-26). Preeclampsia was defined by blood pressure ⩾140/90 mmHg and proteinuria ⩾3 g/24 h. Serum immune biomarkers included interleukin (IL)-6, IL-6 receptor, IL-4, IL-4 receptor, IL-5, IL-12, IL-2, TNF-α, TNF-β, TNF-receptor, IL-1β, IL-1α, IL-8, IL-10, IFN-γ, IL-18, macrophage migration inhibitory factor, macrophage inflammatory protein, transforming growth factor-beta (TGF-β), and RANTES. Associations with preeclampsia, term preeclampsia and preterm preeclampsia were determined using two logistic regression models; (1) biomarkers were dichotomized by the limit of detection (LOD); (2) on the continuous scale, non-detectable values were imputed by LOD/2 and transformed (base 2). All models were adjusted for body mass index and smoking. IL1β was significantly associated with a decrease in the log odds of preeclampsia (p=0.0065), term preeclampsia (p=0.0230) and preterm preeclampsia (p=0.0068). Results were similar for IL4r and preeclampsia (p=0.0383). In the dichotomized models, detectable TNF-β was significantly associated with preeclampsia (ORadj 1.6, 95% CI 1.1-2.3) and term preeclampsia (OR 1.7, 95% CI 1.1-2.5) but not preterm preeclampsia. Detectable IL6 was significantly with term preeclampsia only (OR 1.5, 95% CI 1.1-2.2). Mid-pregnancy circulating IL1β, IL4r, IL6, and TNFβ were associated with preeclampsia. However, results were not consistent across statistical models. As the relationship is complex, future studies should explore cytokine clusters in preeclampsia risk.

Preeclampsia is a major pregnancy complication with cardiovascular manifestations. Recent studies suggest that chocolate consumption may benefit cardiovascular health. We studied the association of chocolate consumption with risk of preeclampsia in a prospective cohort study of 2291 pregnant women who delivered a singleton livebirth between September 1996 and January 2000. Chocolate consumption was measured by self report in the first and third trimesters, and by umbilical cord serum concentrations of theobromine, the major methylxanthine component of chocolate. Preeclampsia was assessed by detailed medical record review for 1943 of the women. We derived adjusted odds ratios (aOR) and 95% confidence intervals (CIs) from logistic regression models controlling for potential confounders. Preeclampsia developed in 3.7% (n = 63) of 1681 women. Cord serum theobromine concentrations were negatively associated with preeclampsia (aOR = 0.31; CI = 0.11-0.87 for highest compared with lowest quartile). Self-reported chocolate consumption estimates also were inversely associated with preeclampsia. Compared with women consuming under 1 serving of chocolate weekly, women consuming 5+ servings per week had decreased risk: aOR = 0.81 with consumption in the first 3 months of pregnancy (CI = 0.37-1.79) and 0.60 in the last 3 months (0.30-1.24). Our results suggest that chocolate consumption during pregnancy may lower risk of preeclampsia. However, reverse causality may also contribute to these findings.

Research on the association between maternal periodontal disease and the risk of preeclampsia has generated inconsistent results. This meta-analysis was conducted to evaluate the association between maternal periodontal disease and the risk of preeclampsia. A literature search of PubMed and Embase was performed to identify relevant papers published before March 2013. Only observational studies that assessed maternal periodontal disease and the risk of preeclampsia were selected. Patients' periodontal status was examined at different time points during pregnancy or after delivery (at 14-32 weeks of gestation, within 48 h prior to or within 5 days after delivery). Pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated for cases and controls. Cases were defined as women with concurrent hypertension and proteinuria after 20 weeks of gestation. Eleven studies involving 1118 women with preeclampsia and 2798 women without preeclampsia were identified and analyzed. Women with periodontal disease before 32 weeks of gestation had a 3.69-fold higher risk of developing preeclampsia than their counterparts without periodontal disease (OR=3.69; 95% CI=2.58-5.27). Periodontal disease within 48 h prior to delivery was associated with a 2.68-fold higher risk of preeclampsia (OR=2.68; 95% CI=1.39-5.18). Pregnant women with periodontal disease within 5 days after delivery had a 2.22-fold higher risk of preeclampsia than women without periodontal disease (OR=2.22; 95% CI=1.16-4.27). In conclusion, this meta-analysis suggests that maternal periodontal disease is an independent predictor of preeclampsia.

Preeclampsia is a hypertensive complication of pregnancy characterized by novel onset of hypertension after 20 weeks gestation, accompanied by proteinuria. Epidemiological evidence suggests that genetic susceptibility exists for preeclampsia; however, whether preeclampsia is the result of underlying genetic risk for essential hypertension has yet to be investigated. Based on the hypertensive state that is characteristic of preeclampsia, we aimed to determine if established genetic risk scores (GRSs) for hypertension and blood pressure are associated with preeclampsia. Subjects consisted of 162 preeclamptic cases and 108 normotensive pregnant controls, all of Iowa residence. Subjects' DNA was extracted from buccal swab samples and genotyped on the Affymetrix Genome-wide Human SNP Array 6.0 (Affymetrix, Santa Clara, CA). Missing genotypes were imputed using MaCH and Minimac software. GRSs were calculated for hypertension, systolic blood pressure (SBP), diastolic blood pressure (DBP), and mean arterial pressure (MAP) using established genetic risk loci for each outcome. Regression analyses were performed to determine the association between GRS and risk of preeclampsia. These analyses were replicated in an independent US population of 516 cases and 1,097 controls of European ancestry. GRSs for hypertension, SBP, DBP, and MAP were not significantly associated with risk for preeclampsia (P > 0.189). The results of the replication analysis also yielded nonsignificant associations. GRSs for hypertension and blood pressure are not associated with preeclampsia, suggesting that an underlying predisposition to essential hypertension is not on the causal pathway of preeclampsia. © American Journal of Hypertension, Ltd 2015.

Dois grupos não gestantes (NGC e NGP foram formados a fim de separarmos os efeitos da gestação. O grupo zero (GO foi sacrificado no 1º dia e aos demais aos 21 dias de experimentação. Pelos resultados concluímos que: a gestação conduziu a uma maior percentagem de gordura na carcaça de GCes e GPces, em relação à NG. Ambas proteínas ensaiadas não conduziram a variações quanto à concentração de nitrogênio nas gestantes. O conteúdo total de nitrogênio foi menor nas gestantes, em relação aos seus pares NG. A mobilização do nitrogênio foi maior na carcaça das gestantes; a gestação propiciou menor retenção na quantidade de nitrogênio, sendo que as proteínas ensaiadas não diferiam entre si. A proteína do pescado propiciou adequada mobilização do nitrogênio com a finalidade de garantir o desenvolvimento fetal.

Preeclampsia continues to afflict 5% to 8% of all pregnancies throughout the world and is associated with significant morbidity and mortality to the mother and the fetus. Although the pathogenesis of the disorder has not yet been fully elucidated, current evidence suggests that imbalance in angiogenic factors is responsible for the clinical manifestations of the disorder, and may explain why certain populations are risk. In this review, we begin by demonstrating the roles that angiogenic factors play in pathogenesis of preeclampsia and its complications in the mother and the fetus. We then continue to report on the use of angiogenic markers as biomarkers to predict and risk-stratify disease. Strategies to treat preeclampsia by correcting the angiogenic balance, either by promoting proangiogenic factors or by removing antiangiogenic factors in both animal and human studies, are discussed. We end the review by summarizing status of the current preventive strategies and the long-term cardiovascular outcomes of women afflicted with preeclampsia. Copyright © 2017 Elsevier Inc.

Preeclampsia remains a leading cause of maternal and fetal mortality, due to ineffective treatment and diagnostic strategies, compounded by the lack of clarity on the etiology of the disorder. Although several clinical and biological markers of preeclampsia have been evaluated, they have proven to be ineffective in providing a definitive diagnosis during the various stages of the disorder. Exosomes have emerged as ideal biomarkers of pathological states, such as cancer, and have more recently gained interest in pregnancy-related complications, due to their role in cellular communication in normal and complicated pregnancies. This occurs as a result of the specific placenta-derived exosomal molecular cargo, which may be involved in normal pregnancy-associated immunological events, such as the maintenance of maternal-fetal tolerance. This review provides perspectives on placenta-derived exosomes as possible biomarkers for the diagnosis/prognosis of preeclampsia. Using keywords, online databases were searched to identify relevant publications to review the potential use of placenta-derived exosomes as biomarkers of preeclampsia.

Full Text Available Children born after preeclampsia may have a dominant androgen profile in puberty compared with other children. Circulating androgen concentrations at 11-12 years of age were compared between offspring born after preeclampsia, and children whose mothers did not have preeclampsia.A total of 611 mother-offspring pairs were followed up 11 (daughters or 12 (sons years after birth: 218 pairs in the preeclampsia group, and 383 pairs without preeclampsia. Circulating total testosterone, androstenedione, dehydroepiandrosterone sulfate (DHEAS, and insulin-like growth factor I (IGF-I were measured in the children. In boys, testicular volume was also measured.Among girls born after preeclampsia, DHEAS concentrations were higher than in unexposed girls (p<0.001, however, girls born after preeclampsia with severe features had the lowest DHEAS levels. In contrast, testosterone concentrations were highest in girls born after preeclampsia with severe features, both compared to other girls in the preeclampsia group, and compared to unexposed girls (p<0.001. For boys, testosterone concentrations were higher in the preeclampsia group compared with unexposed boys (p<0.001, and boys born after preeclampsia with severe features had the lowest concentrations of DHEAS. Compared with unexposed boys, testicular volume (p = 0.015 and IGF-I (p = 0.004 were higher for boys in the preeclampsia group, except for boys in the clinically severe preeclampsia group.In utero exposure to preeclampsia is associated with androgen hormonal patterns in early puberty that depend on clinical severity of preeclampsia and sex of the offspring. The hormonal differences may reflect different timing of pubertal development, and may have consequences for future health of the offspring.

Full Text Available Preeclampsia is a multisystem disorder unique to human pregnancy and is its most common glomerular complication. It occurs in 2% to 8% of pregnancies and is a major contributor to maternal mortality worldwide. Although the pathophysiology of this syndrome is not fully understood, many pathogenetic mechanisms are involved in this disorder. The role of the placenta is crucial in the development of this disorder. Some pathogenetic mechanisms involved in this disease comprise defective deep placentation, autoantibodies to type-1 angiotensin II receptor, endothelial dysfunction, oxidative stress, platelet and thrombin activation, intravascular inflammation, and the imbalance between angiogenic and antiangiogenic factors which is thought to be one of the most crucial mechanisms. Further understanding of the full picture could enhance our current knowledge of the pathogenesis of preeclampsia and improve its treatment. Thus, based on specific biomarkers the diagnosis and subclassification of preeclampsia might be more accurate in identifying patients at risk, monitoring disease progression and providing effective interventions

Introduction. The experience of normal pregnancy is often disrupted for women with preeclampsia (PE). Materials and Methods. Postal survey of the 112 members of the consumer group, Australian Action on Pre-Eclampsia (AAPEC). Results. Surveys were returned by 68 women (61% response rate) and from 64 (57%) partners, close relatives or friends. Respondents reported experiencing pre-eclampsia (n = 53), eclampsia (n = 5), and/or Hemolysis, Elevated Liver enzymes, and Low Platelets (HELLP syndrome) (n = 26). Many women had no knowledge of PE prior to diagnosis (77%) and, once diagnosed, did not appreciate how serious or life threatening it was (50%). Women wanted access to information about PE. Their experience contributed substantial anxiety towards future pregnancies. Partners/friends/relatives expressed fear for the woman and/or her baby and had no prior understanding of PE. Conclusions. The PE experience had a substantial effect on women, their confidants, and their babies and affected their approach to future pregnancies. Access to information about PE was viewed as very important.

To determine if preeclampsia is an independent predictor of diastolic dysfunction and what factors among patients with preeclampsia are associated with diastolic dysfunction. This is a retrospective cohort study of patients who delivered between 2008 and 2013 at a single institution who had a maternal echocardiogram during their pregnancy or within 5months of delivery. Patients with structural heart disease, ejection fraction less than 45%, pulmonary embolus, or age over 45years were excluded. Medical records were reviewed for medical and obstetric complications and echocardiogram findings. Demographic characteristics and rate of diastolic dysfunction were compared between patients with preeclampsia and without preeclampsia. Multivariate logistic regression was performed controlling for age, ethnicity, gestational age at delivery, diabetes, preeclampsia, intrauterine growth restriction (IUGR), antihypertensive use and magnesium sulfate administration. Sixty-six patients were identified, of which 39 (59%) had preeclampsia. Past history of preeclampsia, IUGR in the current pregnancy, antihypertensive use and magnesium sulfate use were higher in the preeclampsia group. Fifteen patients (39%) in the preeclampsia group were African-American compared to 2 (3%) in the control group (ppreeclampsia were found to have diastolic dysfunction compared to 3 (11%) controls (OR=6.18, 95% CI 1.59,24.02; p=0.006). Logistic regression analysis did not reveal other independent predictors of diastolic dysfunction. In the patients with preeclampsia, history of preeclampsia with severe features and IUGR were not associated with diastolic dysfunction. Our study supports previous findings that preeclampsia is associated with diastolic dysfunction. Copyright © 2015 International Society for the Study of Hypertension in Pregnancy.

Full Text Available Infection with Group B Streptococcus (GBS is considered an important public health problem. It is associated with: Neonatal sepsis, meningitis, pneumonia, neonatal death, septic abortion, chorioamnionitis, endometritis and other perinatal infections. The aim of this study was to determine the best screening strategy for GBS in pregnant women. For this a systematic review and meta-analysis were carried out in the Nursing Department of the Federal University of São Paulo, Cochrane Center, Brazil. Sources used were, EMBASE, LILACS, Medline, list of references, personal communication and the Cochrane library. The criterion for the selection of the studies was; studies which analyze some type of screening for GBS in pregnant women. Independent of the comparator, all analyses were in favor of a universal screening program for reducing the incidence of neonatal sepsis. The evidence obtained in this study suggests that the strategy of universal screening of pregnant women associated with the use of prophylactic antibiotics is safe and effective.La infección por Streptococcus del grupo B (GBS es considerada un importante problema de salud pública.

Full Text Available Objective. To investigate the efficacy of antioxidants for preventing preeclampsia and other maternal and fetal complications among pregnant women with low, moderate, or high risk of preeclampsia. Methods. We searched MEDLINE, Embase, CENTRAL, mRCT, and other databases, with no language or publication restrictions. Two independent reviewers selected randomized controlled trials that evaluated the use of antioxidants versus placebo and extracted the relevant data. Relative risks (RRs and 95% confidence intervals (95% CIs were calculated. The data were compiled through the random effects model. Main Results. Fifteen studies were included (21,012 women and 21,647 fetuses. No statistically significant difference was found between women who received antioxidant treatment and women who received placebo for preeclampsia (RR =0.92; 95% CI: 0.82–1.04, severe preeclampsia (RR =1.03; 95% CI: 0.87–1.22, preterm birth (RR =1.03; 95% CI: 0.94–1.14, and small for gestational age <10th centile (RR =0.92; 95% CI: 0.80–1.05. Side effects were numerically more frequent in the antioxidants group compared to placebo, but without significant statistical difference (RR =1.24; 95% CI: 0.85–1.80. Conclusions. The available evidence reviewed does not support the use of antioxidants during pregnancy for the prevention of preeclampsia and other outcomes.

Full Text Available Resumo A imagem corporal de gestantes deve ser alvo de atenção por parte dos profissionais, tendo em vista a promoção da saúde materna infantil. O objetivo da presente revisão integrativa foi analisar a literatura sobre imagem e insatisfação corporal em gestantes. Foram buscados artigos nas bases de dados Scopus, PubMed, BVS e PsycINFO utilizando o cruzamento de “pregnancy” com as palavras-chave: “body image” e “body dissatisfaction”. Após a adoção dos critérios de inclusão e exclusão foram analisados 40 estudos. Estes apontam dados inconclusivos quanto à insatisfação corporal durante a gestação. Presença de sintomas depressivos, baixa autoestima, atitude alimentar inadequada e ganho de peso fora dos limites recomendados têm sido associados a uma imagem corporal negativa. Contradições nos achados podem estar relacionados às diferenças nos instrumentos utilizados para mensurar a imagem corporal. Pelo possível impacto de uma imagem corporal negativa durante a gestação na saúde materna e infantil, são recomendadas novas investigações, em especial o desenvolvimento de um instrumento avaliativo de imagem corporal específico para gestantes.

The relationship between gestational hypertension, preeclampsia, and the risk of retinopathy of prematurity (ROP) remains unclear. Thus, we used a large cohort database to study the influence of maternal gestational hypertension and preeclampsia on the occurrence of ROP in preterm infants. We used data from a previous retrospective cohort study that includes 25,473 eligible preterm neonates. We examined the association between gestational hypertension, preeclampsia, and ROP while controlling for potential confounders by multiple logistic regression analysis. Of the 8758 early preterm infants (gestational age <34 weeks), 1024 (11.69%) had ROP, while of the 16,715 late preterm infants, only 29 (0.17%) had ROP. After adjusting for confounders, preeclampsia was associated with a significantly reduced risk of ROP (adjusted odds ratio [aOR], 0.65; 95% confidence interval [CI], 0.49-0.86 for early preterm birth; aOR, 0.10; 95% CI, 0.01-0.93 for late preterm birth; aOR, 0.66; 95% CI, 0.50-0.87 for all preterm births). Gestational hypertension was not significantly associated with ROP at early or late preterm births. Preeclampsia, but not gestational hypertension, was associated with a reduced risk of ROP in preterm births.

Full Text Available Pre-eclampsia is a condition affecting the feto-placental unit and the mother. Three to five percent of pregnancies are complicated by pre-eclampsia, a multisystem disorder characterized by hypertension and proteinuria that occurs after 20 weeks of pregnancy. Pre-eclampsia is associated with substantial risks. For the fetus, these include intrauterine growth restriction, death, and prematurity with attendant complications, whereas the mother is at risk for complications of widespread alterations in endothelial function such as seizures (eclampsia, renal failure, pulmonary edema, stroke, and death. The establishment of pathological uterine perfusion raises the problem of stage two. The problem at stage three describes pre-eclampsia as a syndrome with the global maternal endothelial damage as the central pathophysiological feature.\tIt has been suggested that the pathophysiology of pre-eclampsia can be thought of as a ‘three-stage problem’, where each stage generates one, so far unsolved problem. An impaired trophoblast invasion is thought to be the central factor (first step regarding the etiology of pre-eclampsia. An increased uterine artery Doppler findings (PI, RI, lower maternal serum PAPP-A and free ßhCG levels, ischaemia modified albumin (IMA may be associated with pre-eclampsia.

Preeclampsia is an important pregnancy-specific multisystem disorder characterized by the onset of hypertension and proteinuria. It is of unknown etiology and involves serious risks for the pregnant women and fetus. One of the main factors involved in the pathophysiology of preeclampsia is oxidative stress, where excess free radicals produce harmful effects, including damage to macromolecules such as lipids, proteins and DNA. In addition, the sulfhydryl delta-aminolevulinate dehydratase enzyme (δ-ALA-D) that is part of the heme biosynthetic pathway in pro-oxidant conditions can be inhibited, which may result in the accumulation of 5-aminolevulinic acid (ALA), associated with the overproduction of free radicals, suggesting it to be an indirect marker of oxidative stress. As hypertensive pregnancy complications are a major cause of morbidity and mortality maternal and fetal where oxidative stress appears to be an important factor involved in preeclampsia, the aim of this study was to evaluate the activity of δ-ALA-D and classic oxidative stress markers in the blood of pregnant women with mild and severe preeclampsia. The analysis and quantification of the following oxidative stress markers were performed: thiobarbituric acid-reactive species (TBARS); presence of protein and non-protein thiol group; quantification of vitamin C; Catalase and δ-ALA--D activities in samples of blood of pregnant women with mild preeclampsia (n=25), with severe preeclampsia (n=30) and in a control group of healthy pregnant women (n=30). TBARS was significantly higher in women with preeclampsia, while the presence of thiol groups, levels of vitamin C, catalase and δ-ALA-D activity were significantly lower in groups of pregnant women with preeclampsia compared with healthy women. In addition, the results showed no significant difference between groups of pregnant women with mild and severe preeclampsia. The data suggest a state of increased oxidative stress in pregnant women with

2017-04-01

To assess the magnitude of familial risk of preeclampsia and gestational hypertension in women born of a preeclamptic pregnancy and those born of pregnancy complicated by gestational hypertension while accounting for other risk factors. An intergenerational dataset was extracted from the Aberdeen Maternity and Neonatal Databank (AMND) which records all pregnancy and delivery details occurring in Aberdeen, Scotland since 1950. The analysis included all nulliparous women whose mothers' records at their births are also recorded in the AMND. Multinomial logistic regression was used to assess the risk of having preeclampsia or gestational hypertension based on maternal history of preeclampsia or gestational hypertension. There were 17302 nulliparous women included, of whom 1057(6.1%) had preeclampsia while 4098(23.7%) had gestational hypertension. Furthermore, 424(2.5%) and 2940(17.0%) had maternal history of preeclampsia and gestational hypertension respectively. The risk of preeclampsia was higher in women who were born of pregnancies complicated by preeclampsia (adjusted RRR 2.55 95% CI 1.87-3.47). This was higher than the risk observed in women whose mothers had gestational hypertension (adjusted RRR 1.44 95% CI 1.23-1.69). Conversely, the risk of gestational hypertension was similar in those who were born of preeclamptic pregnancies (adjusted RRR 1.37 95% CI 1.09-1.71) and those whose mothers had gestational hypertension (adjusted RRR 1.36 95% CI 1.24-1.49). There was a dose response effect in the inheritance pattern of preeclampsia with the highest risk in women born of preeclamptic pregnancies. Gestational hypertension showed similar increased risk with maternal gestational hypertension and preeclampsia. Copyright © 2017 International Society for the Study of Hypertension in Pregnancy.

2013-09-01

Secondary hyperparathyroidism, which is defined by a high concentration of intact parathyroid hormone when circulating 25-hydroxyvitamin D [25(OH)D] is low, is a functional indicator of vitamin D insufficiency and a sign of impaired calcium metabolism. Two large randomized controlled trials examined effects of calcium supplementation on preeclampsia but did not consider the vitamin D status of mothers. We examined the association of secondary hyperparathyroidism with risk of preeclampsia. Circulating maternal 25-hydroxyvitamin D [25(OH)D] and intact parathyroid hormone were measured at entry to care (mean ± SD: 13.7 ± 5.7 wk) using prospective data from a cohort of 1141 low-income and minority gravidae. Secondary hyperparathyroidism occurred in 6.3% of the cohort and 18.4% of women whose 25(OH)D concentrations were 20 ng/mL were not at increased risk. Intact parathyroid hormone was related to higher systolic and diastolic blood pressures and arterial pressure at week 20 before clinical recognition of preeclampsia. Energy-adjusted intakes of total calcium and lactose and circulating 25(OH)D were correlated inversely with systolic blood pressure or arterial pressure and with parathyroid hormone. Some women who are vitamin D insufficient develop secondary hyperparathyroidism, which is associated with increased risk of preeclampsia.

Full Text Available Desconocemos aún la etiología de la preeclampsia, pero ahora sabemos que no es sólo una hipertensión inducida por el embarazo, sino que existe interacción entre una perfusión placentaria disminuida y la alteración en la función endotelial materna, probablemente por razones inmunológicas de rechazo parcial a la placentación normal. La contribución materna es de factores que anteceden al embarazo, influenciados por las adaptaciones metabólicas usuales. No existe un gen único que pueda explicar la preeclampsia, pero conocer la predisposición materna permite prevenir la preeclampsia en un grupo de mujeres.

Impaired placento-fetal communication is a coherent symptom of exaggerated pre-eclampsia. The impact of the cellular expression of different glycosaminoglycans (GAGs) in this event on the placenta in pre-eclampsia is still obscure. This is the first study aimed at discovering the relationship between structural alterations of different sulfated GAGs at the molecular level and the development of pre-eclampsia in inflicted placenta. Sulfated GAGs were isolated and purified from control and pre-...

Full Text Available The review presents the results of an analysis of the data available in the Russian and foreign literature, which show that severe gestosis (preeclampsia is a main cause of perinatal morbidity and mortality. Severe gestosis leads to impaired fetal growth and development, premature births, the development of perinatal hypoxic lesions of the central nervous, cardiovascular, endocrine, immune, respiratory, and other systems, which adversely affects the health status of children in their later life. Women with a history of preeclampsia or eclampsia are further at increased risk for cardiovascular (atherosclerosis, coronary heart disease, peripheral arterial diseases, and hypertension, cerebrovascular diseases, abnormalities of the kidney and organs of vision, diabetes, and memory impairments.

Preeclampsia affects 3% to 8% of pregnancies and increases risk of pregnancy-associated stroke (PAS). Data are limited on which women with preeclampsia are at highest risk for PAS. Using billing data from the 2003 to 2012 New York State Department of Health inpatient database, we matched women with preeclampsia and PAS 1:3 to preeclamptic controls based on age and race/ethnicity. Pre-defined PAS risk factors included pregnancy complications, infection present on admission, vascular risk factors, prothrombotic states, and coagulopathies. We constructed multivariable conditional logistic regression models to calculate the odds ratios (ORs) and 95% confidence intervals (95% CIs) for independent risk factors for PAS. Among women aged 12 to 55 years admitted to New York State hospitals for any reason during the study period (n=3 373 114), 88 857 had preeclampsia, and 197 of whom (0.2%) had PAS. In multivariable analysis, women with preeclampsia and stroke were more likely than controls to have severe preeclampsia or eclampsia (OR, 7.2; 95% confidence interval [CI], 4.6-11.3), infections present on admission (OR, 3.0; 95% CI, 1.6-5.8), prothrombotic states (OR, 3.5; 95% CI, 1.3-9.2), coagulopathies (OR, 3.1; 95% CI, 1.3-7.1), or chronic hypertension (OR, 3.2; 95% CI, 1.8-5.5). Additional analyses matched and stratified by severity of preeclampsia confirmed these results. Infections, chronic hypertension, coagulopathies, and underlying prothrombotic conditions increase PAS risk in women with preeclampsia. These women may warrant closer monitoring. © 2017 American Heart Association, Inc.

Preeclampsia is a common and heterogeneous vascular syndrome of pregnancy. Its genetic risk profile is yet unknown and may vary between individuals and populations. The rs4606 3' UTR polymorphism of the Regulator of G-protein signaling 2 gene (RGS2) in the mother has been implicated in preeclampsia as well as in the development of chronic hypertension after preeclampsia. The RGS2 protein acts as an inhibitor of physiological vasoconstrictive pathways, and a low RGS2 level is associated with hypertension and obesity, two conditions that predispose to preeclampsia. We genotyped the rs4606 polymorphism in 1339 preeclamptic patients and in 697 controls from the Finnish Genetics of Preeclampsia Consortium (FINNPEC) cohort to study the association of the variant with preeclampsia. No association between rs4606 and preeclampsia was detected in the analysis including all women. However, the polymorphism was associated with preeclampsia in a subgroup of overweight women (body mass index ≥ 25 kg/m(2), and preeclampsia particularly in overweight women and contribute to their increased risk for hypertension and other types of cardiovascular disease later in life.

Association of intake of trans fatty acids in the 2nd trimester of pregnancy with risk of preeclampsia was studied by following 67 186 pregnancies of women participating in the Danish National Birth Cohort between 1998 and 2003. Diet was assessed with a food frequency questionnaire at gestation wk...... 25; preeclampsia diagnosis was obtained by linkage with the Danish National Patient Registry. 1804 cases of preeclampsia and 402 cases of severe preeclampsia were identified in the cohort. Intake of trans fats decreased during the study period as a consequence of reduction in industrial trans fat...... intake. Intake of trans fats in the 2nd trimester was unrelated to risk of preeclampsia or severe preeclampsia. Relative risk (95% confidence interval; P, trend) of preeclampsia and severe preeclampsia comparing top to bottom quintiles of trans fat intake were 0.95 (0.81; 1.11, 0.33) and 1.07 (0.78; 1...

Preeclampsia is a multisystem disorder whose etiology remains unclear. It is already known that circulation of soluble fms-like tyrosine kinase-1 (sFlt-1) is directly involved in pre-eclampsia development. However, the molecular mechanisms involved with sFlt-1 shedding are still unidentified. We identified, quantified glycosaminoglycans and determined the enzymatic activity of heparanase in placentas of women with preeclampsia, in order to possibly explain if these compounds could be related to cellular processes involved with preeclampsia. A total of 45 samples collected from placentas, 15 samples from placentas of preeclampsia women and 30 samples from non-affected women. Heparan sulfate and dermatan sulfate were identified and quantified by agarose gel electrophoresis, whilst hyaluronic acid was quantified by an ELISA like assay. Heparanase activity was determined using biotynilated heparan sulfate as substrate. The results showed that dermatan sulfate (P=0.019), heparan sulfate levels (P=0.015) and heparanase activity (P=0.006) in preeclampsia were significantly higher than in the control group. There was no significant difference between the groups for hyaluronic acid expression in placentas (P=0.110). The present study is the first to demonstrate directly the increase of heparan sulfate in human placentas from patients with preeclampsia, suggesting that endogenous heparan sulfate could be involved in the release of sFlt-1 from placenta, increasing the level of circulating sFlt-1. Alterations of extracellular matrix components in placentas with preeclampsia raise the possibility that heparan sulfate released by heparanase is involved in mechanisms of preeclampsia development.

Soma-Pillay, P; Louw, M C; Adeyemo, A O; Makin, J; Pattinson, R C

Pre-eclampsia is associated with significant changes to the cardiovascular system during pregnancy. Eccentric and concentric remodelling of the left ventricle occurs, resulting in impaired contractility and diastolic dysfunction. It is unclear whether these structural and functional changes resolve completely after delivery. The objective of the study was to determine cardiac diastolic function at delivery and one year post-partum in women with severe pre-eclampsia, and to determine possible future cardiovascular risk. This was a descriptive study performed at Steve Biko Academic Hospital, a tertiary referral hospital in Pretoria, South Africa. Ninety-six women with severe preeclampsia and 45 normotensive women with uncomplicated pregnancies were recruited during the delivery admission. Seventy-four (77.1%) women in the pre-eclamptic group were classified as a maternal near miss. Transthoracic Doppler echocardiography was performed at delivery and one year post-partum. At one year post-partum, women with pre-eclampsia had a higher diastolic blood pressure (p = 0.001) and body mass index (p = 0.02) than women in the normotensive control group. Women with early onset pre-eclampsia requiring delivery prior to 34 weeks' gestation had an increased risk of diastolic dysfunction at one year post-partum (RR 3.41, 95% CI: 1.11-10.5, p = 0.04) and this was irrespective of whether the patient had chronic hypertension or not. Women who develop early-onset pre-eclampsia requiring delivery before 34 weeks are at a significant risk of developing cardiac diastolic dysfunction one year after delivery compared to normotensive women with a history of a low-risk pregnancy.

Preeclampsia is clinically divided into early onset and late onset preeclampsia based on the gestational age at delivery. Although the diagnostic criteria are the same in each subgroup of preeclampsia, it has been suggested that the maternal and perinatal mortalities of early onset and late onset preeclampsia are different. However, studies that compare clinical parameters or laboratory biomarkers between early onset and late onset preeclampsia are limited. Data on 177 women with early or late preeclampsia with severe hypertension were collected from a University Teaching Hospital from January 2010 to January 2011 and analysed. Data included all the clinical parameters and laboratory biomarkers of liver and renal function. 63 women and 114 women were diagnosed with early and late preeclampsia with severe hypertension, respectively. There was no difference in the maternal age and the incidence of clinical symptoms including edema, vision disturbance, severe headache and stillbirth between two groups. There was a decrease in alkaline phosphatase levels in early preeclampsia with severe hypertension but other markers of liver function were not altered. However, renal function including blood urea nitrogen, creatinine and uric acid were significantly higher in early preeclampsia with severe hypertension. Umbilical artery systolic velocity/diastolic velocity ratio was significantly higher in early preeclampsia with severe hypertension. Our data demonstrates that the laboratory biomarkers of renal function differ between early and late preeclampsia with severe hypertension. The severity of renal dysfunction correlated with the time of delivery in preeclampsia with severe hypertension. Copyright © 2015 International Society for the Study of Hypertension in Pregnancy.

Preeclampsia is characterized by generalized endothelial dysfunction and impaired maternal tissue perfusion, and insulin resistance is a prominent feature of this disease. The aim of this study was to test the hypothesis that insulin resistance in preeclampsia is related to the reduced resting tissue blood flow. We used venous occlusion plethysmography to compare the resting calf muscle blood flow (measured as QaU) in 20 nulliparous women with preeclampsia and 20 normal pregnant controls matched for maternal age, gestational age, parity and BMI during the third trimester. Fasting blood samples were obtained to measure the plasma concentrations of insulin and glucose, and to calculate the fasting insulin resistance index (FIRI), a measure of insulin resistance in both groups of women. Calf blood flow was significantly reduced in the preeclampsia group (1.93 ± 0.86 QaU), compared with normal pregnant controls (3.94 ± 1.1 QaU, P insulin concentrations and Insulin Resistance Index were significantly higher in preeclampsia compared with normal pregnancy (P insulin concentrations (r = -0.57, P = 0.008) and FIRI (r = -0.59, P = 0.006) in preeclampsia, but not in normal pregnancy. These findings support our hypothesis and raise the possibility that reduced tissue blood flow may a play a role in the increased insulin resistance seen in preeclampsia.

The objective of this study is to determine the differences in histopathological features of basal decidua and placenta in cases of preeclampsia with or without fetal intrauterine growth restriction (IUGR). A prospective case-control study included a study group consisting of 30 pregnant women with preeclampsia completed by cesarean section (CS), in 19 of whom preeclampsia was associated with IUGR, and in 11 it was not. The control group consisted of 20 healthy pregnant women delivered by elective CS. Placentas and samples of placental bed obtained during CS were histopathologically (HP) analyzed after hematoxylin-eosin staining and immunohistochemical labeling of Cytokeratin 7 (CK7) trophoblastic cells in decidua. Regarding the HP changes in the spiral arteries in preeclampsia, the most frequent features were inadequate transformation of spiral arteries with poor trophoblastic invasion (70.0%) and fibrinoid necrosis of the media (66.7%), and rarely acute atherosis (33.3%) and thrombosis (30.0%). Villous hypermaturity was more frequently found in placentas of patients with preeclampsia with IUGR (p preeclampsia with and without IUGR regarding some of HP alterations of placental bed. Alterations of the placental bed in terms of decidual vasculopathy are more the characteristics of the preeclampsia itself than IUGR, while changes in placental villi primarily follow the presence of IUGR, which could indicate that preeclampsia with and without IUGR are two pathogenetically different entities.

Probiotics have been suggested to modify placental trophoblast inflammation, systemic inflammation, and blood pressure, all potentially interesting aspects of preeclampsia. The authors examined the association between consumption of milk-based probiotic products in pregnancy and development of preeclampsia and its subtypes. The study was performed in the Norwegian Mother and Child Cohort Study by using a prospective design in 33,399 primiparous women in the years 2002–2008. The intake of milk-based products containing probiotic lactobacilli was estimated from a self-reported food frequency questionnaire. Preeclampsia diagnoses were obtained from the Norwegian Medical Birth Registry. Intake of probiotic milk products was associated with reduced risk of preeclampsia. The association was most prominent in severe preeclampsia (adjusted odds ratio (OR) = 0.79, 95% confidence interval (CI): 0.66, 0.96). With probiotic intakes divided into categories representing no, monthly, weekly, or daily intake, a lower risk for preeclampsia (all subtypes) was observed for daily probiotic intake (OR = 0.80, 95% CI: 0.66, 0.96). Lower risks for severe preeclampsia were observed for weekly (OR = 0.75, 95% CI: 0.57, 0.98) and daily (OR = 0.61, 95% CI: 0.43, 0.89) intakes. These results suggest that regular consumption of milk-based probiotics could be associated with lower risk of preeclampsia in primiparous women. PMID:21821542

OBJECTIVE: Clinical observations suggest a role for the fetus in the maternal manifestations of preeclampsia, but the possible signaling mechanisms remain unclear. This study compares the fetal plasma concentrations of adenosine from normal pregnancies with those from preeclampsia. STUDY DESIGN: This secondary data analysis included normal pregnancies (n = 27) and patients with preeclampsia (n = 39). Patients with preeclampsia were subclassified into patients with (n = 25) and without (n = 14) abnormal uterine artery Doppler velocimetry (UADV). RESULTS: Fetal plasma concentrations of adenosine were significantly higher in patients with preeclampsia (1.35 +\\/- 0.09 mumol\\/L) than in normal pregnancies (0.52 +\\/- 0.06 mumol\\/L; P < .0001).

Cell-free fetal DNA in maternal plasma is associated with complications of pregnancy, including preeclampsia. Determination of levels is affected by fetal gender and genetic polymorphisms. Unmethylated maspin (u-maspin) is present in the placenta, and is placental-specific. The purpose of this study was to determine whether u-maspin DNA in maternal blood could serve as a marker of preeclampsia by measuring levels in different trimesters of normal pregnancies and in those complicated by preeclampsia. This case-control study was set in a tertiary care hospital. The population consisted of 45 women with normal pregnancies (15 in the 1st trimester, 15 in the 2nd trimester, 15 in the 3rd trimester), 20 women with mild preeclampsia, 25 women with severe preeclampsia, and six women with gestational trophoblastic disease. Peripheral blood was collected and methylation-specific PCR and fluorescence quantitative PCR were performed to measure the content of u-maspin DNA in maternal blood. U-maspin DNA was 5.5-fold higher in women with severe preeclampsia than in those with a normal 3rd trimester pregnancy (p preeclampsia. © 2015 Nordic Federation of Societies of Obstetrics and Gynecology.

Preeclampsia is defined by the American College of Obstetrics and Gynecology (ACOG) as "the occurrence of new onset hypertension plus new-onset proteinuria" [1]. Up-to-Date elaborates a little further on this by defining preeclampsia as "the new onset of hypertension and proteinuria, or hypertension and end-organ dysfunction with or without proteinuria, after 20 weeks of gestation in a previously normotensive woman. It may also develop postpartum. Severe hypertension or signs/symptoms of end-organ injury represent the severe end of the disease spectrum" [2] In 2013, the American College of Obstetricians and Gynecologists removed proteinuria as a key component in the diagnosis of preeclampsia. They also removed massive proteinuria (previously, 5 g/24 hours) and fetal growth restriction as possible features of severe disease. They found that were was a poor correlation in many outcomes between massive proteinuria and fetal growth restriction when managed similarly, with or without preeclampsia as a diagnosis. Oliguria was also removed as a characteristic of severe disease. [3] There have been several cases reported in the literature as well as by Obstetricians citing the incidence of preeclampsia occurring upwards of 6 to even 12 weeks postpartum. We hope to demonstrate what we believe to be a case of postpartum preeclampsia at 89 days postpartum. Published by Elsevier Inc.

Preeclampsia is a complication affecting pregnant women worldwide, which leads to maternal and fetal morbidity and mortality. In this study, we evaluated the efficacy of ferulic acid (FA) on an N ω -nitro-L-arginine methyl ester hydrochloride (L-NAME) induced rat model of preeclampsia. L-NAME was administered to pregnant rats to induce preeclampsia. 48 rats were divided into three experimental groups (n=16 each): control group, preeclampsia group and preeclampsia with FA treatment (preeclampsia+FA). Physiological characteristics such as urine volume, total urine protein and blood pressure were assessed. Expressions levels of urinary nephrin and podocin mRNAs were analyzed by RT-PCR. Levels of renal vascular endothelial growth factor (VEGF), renal soluble fms-like tyrosine kinase-1 (sFlt-1) and serum placenta growth factor (PlGF) were also examined. Urine volume, total urine protein and blood pressure were markedly increased in preeclampsia group rats compared to control (Ppreeclampsia+FA group (Ppreeclampsia+FA group compared to preeclampsia rats (Ppreeclampsia symptoms in a rat preeclampsia model, supporting its potential value in treating preeclampsia. © 2017 John Wiley & Sons Australia, Ltd.

Massive vulvar edema in a woman with preeclampsia preceded the development of massive ascites and impending eclampsia. A 17-year-old preeclamptic, primiparous woman was admitted with preeclampsia and massive vulvar edema. Other causes were excluded. The vulvar edema increased as the blood pressure and ascites increased, and a severe headache developed. Cesarean section for increasing preclampsia was performed. In the puerperium, the blood pressure improved and vulvar edema resolved. The clinical picture of the vulvar edema correlated with the severity of the preeclampsia. The presence of vulvar edema in women with preeclampsia should indicate immediate admission to the hospital. These patients must be considered as at high risk, and close monitoring must be instituted. In our case, vulvar edema preceded massive ascites development. We assume a common development mechanism for these signs in preeclampsia, due mainly to increased capillary permeability and hypoalbuminemia. The attending physician must be prepared for immediate delivery and possible preeclampsia complications in these patients.

Preeclampsia is a leading cause of maternal morbidity. The clinical challenge lies in predicting which women with preeclampsia will suffer adverse outcomes and would benefit from treatment, while minimizing potentially harmful interventions. Our aim was to determine the ability of maternal symptoms (i.e., severe nausea or vomiting, headache, visual disturbance, right upper quadrant pain or epigastric pain, abdominal pain or vaginal bleeding, and chest pain or dyspnea) to predict adverse maternal or perinatal outcomes. We used data from the PIERS (Pre-eclampsia Integrated Estimate of RiSk) study, a multicentre, prospective cohort study designed to investigate the maternal risks associated with preeclampsia. Relative risks and receiver operating characteristic (ROC) curves were assessed for each preeclampsia symptom and outcome pair. Of 2023 women who underwent assessment, 52% experienced at least one preeclampsia symptom, with 5.2% and 5.3% respectively experiencing an adverse maternal or perinatal outcome. No symptom and outcome pair, in either of the maternal or perinatal groups, achieved an area under the ROC curve value > 0.7, which would be necessary to demonstrate a discriminatory predictive value. Maternal symptoms of preeclampsia are not independently valid predictors of maternal adverse outcome. Caution should be used when making clinical decisions on the basis of symptoms alone in the preeclamptic patient.

The purpose of this study was to develop a model for preeclampsia based on maternal demographic characteristics and medical history. This was a screening study of 120,492 singleton pregnancies at 11-13 weeks' gestation, including 2704 pregnancies (2.2%) that experienced preeclampsia. A survival-time model for the gestational age at delivery with preeclampsia was developed from variables of maternal characteristics and history. This approach assumes that, if the pregnancy was to continue indefinitely, all women would experience preeclampsia and that whether they do so or not before a specified gestational age depends on competition between delivery before or after development of preeclampsia. A 5-fold cross validation study was conducted to compare the performance of the new model with the National Institute for Health and Clinical Excellence (NICE) guidelines. In the new model, increased risk for preeclampsia, with a consequent shift in the Gaussian distribution of the gestational age at delivery with preeclampsia to the left, is provided by advancing maternal age, increasing weight, Afro-Caribbean and South Asian racial origin, medical history of chronic hypertension, diabetes mellitus and systemic lupus erythematosus or antiphospholipid syndrome, family history and personal history of preeclampsia, and conception by in vitro fertilization. The risk for preeclampsia decreases with increasing maternal height and in parous women with no previous preeclampsia; in the latter, the protective effect, which is related inversely to the interpregnancy interval, persists beyond 15 years. At a screen-positive rate of 11%, as defined by NICE, the new model predicted 40%, 48%, and 54% of cases of total preeclampsia and preeclampsia requiring delivery at preeclampsia. Such estimation of the a priori risk for preeclampsia is an essential first step in the use of Bayes theorem to combine maternal factors with biomarkers for the continuing development of more effective methods of

Preeclampsia and intrauterine growth restriction are two separate disease entities that, according to numerous reports, share the same pathogenesis. In both, angiogenesis disorders and generalized inflammation are the dominant symptoms. In this study, we hypothesized that both diseases demonstrate the same profile in early preeclampsia, late preeclampsia, and intrauterine growth restriction patients, with the only difference being the degree of exacerbation of lesions. One hundred sixty-seven patients were enrolled in the study and divided into four groups: early preeclampsia, late preeclampsia, and intrauterine growth restriction groups, and one control group. Concentrations of the angiogenesis and inflammatory markers soluble fms-like tyrosine kinase receptor 1, placental growth factor, high-sensitivity C-reactive protein, and interleukin-6 were determined, and the behavior of these markers and correlations among them were studied. Higher concentrations of soluble fms-like tyrosine kinase receptor 1, high-sensitivity C-reactive protein, and interleukin-6 and a lower concentration of placental growth factor were observed in the study groups compared with the control group. No differences in concentrations of the studied markers were found among the study groups but significant correlations were observed. The higher values for the angiogenesis and inflammatory markers both in preeclampsia patients and patients with intrauterine growth restriction of placental origin compared with the control group suggest the existence of the same underlying disorders in the development of these pathologies. The observed mutual correlations for disordered angiogenesis and inflammatory markers are suggestive of a mutual relationship between these processes in the development of pathologies evolving secondary to placental ischemia. The same lesion profile was observed for both preeclampsia and 'placental' intrauterine growth restriction patients, which could be used in developing

The potential impact of employment on maternal health, particularly in relation to gestational hypertension and pre-eclampsia, has been subject to research. However, there is limited evidence on associations between shift work and long working hours on the incidence of these conditions. To evaluate potential associations between maternal shift work and long working hours during pregnancy and gestational hypertension or pre-eclampsia. Multistage stratified systematic sampling was used to recruit 24 200 post-partum women from the Taiwan national birth registration database in 2005. Subjects underwent home interview 6 months after their deliveries by structured questionnaire to obtain characteristics of maternal employment and potential confounders. Diagnosis of gestational hypertension and pre-eclampsia was obtained from the birth registration. There was no association between employment status and gestational hypertension or pre-eclampsia. Also, no significant association between gestational hypertension or pre-eclampsia and maternal shift work or long working hours during pregnancy was found in all or primiparous women. There was no convincing evidence that maternal shift work or long working hours had a higher risk of gestational hypertension or pre-eclampsia. However, further research is warranted to confirm these negative findings.

Full Text Available Introduction: Preeclampsia is an exacerbation of a generalized inflammatory response, physiologically present in the third trimester of pregnancy.Aim: The aim of the study consists in the evaluation of proinflammatory cytokine TNF-α in the context of preeclampsia. Material and Method: A transversal study was performed in three groups of patients: non-pregnant patients, patients with normal pregnancies in the third trimester, patients with preeclampsia. Serum TNF-α levels were determined using the immunometric sandwich EIA method.Results: The results obtained confirm a significant increase (p<0.01 in circulating TNF-α levels in the last trimester of pregnancy, compared to the non-pregnant status. Significantly increased serum TNF-α concentrations (p<0.001 were also found in pregnant patients with preeclampsia, compared to normotensive pregnant women. Conclusion: This proinflammatory cytokine can be a potential marker of the severity of the preeclamptic syndrome, without being an indicator of the fetal status at birth.

Full Text Available BACKGROUND: Preeclampsia, characterized by hypertension and proteinuria, is a multifactorial disease caused by complex interactions between environmental and genetic factors. A recent genome-wide association study of blood pressure reported an association between hypertension and rs11646213. This study evaluated the association between preeclampsia and rs11646213. METHODS: A total of 454 cases and 460 controls were recruited to participate in this study. The single nucleotide polymorphism (SNP rs11646213 was genotyped by polymerase chain reaction (PCR and direct sequencing. RESULTS: The allele frequency of rs11646213 was significantly different between the preeclampsia and control groups (P = 0.017, OR = 1.36, 95% CI = 1.06-1.76. Differences were particularly significant in the severe preeclampsia subgroup (P = 0.002, OR = 1.54, 95% CI = 1.17-2.03 and the early-onset preeclampsia subgroup (P = 0.004, OR = 1.57, 95% CI = 1.16-2.13. Genotyping analysis showed that the T allele of rs11646213 could confer a risk for preeclampsia, severe preeclampsia and early-onset preeclampsia. CONCLUSIONS: Rs11646213 upstream of the CDH13 gene is associated with preeclampsia in Han Chinese women.

Bell palsy is a facial nerve neuropathy that is a rare disorder but occurs at higher frequency in pregnancy. Almost 30% of cases are associated with preeclampsia or gestational hypertension. Bilateral Bell palsy occurs in only 0.3%-2.0% of cases of facial paralysis, has a poorer prognosis for recovery, and may be associated with a systemic disorder. We describe a case of a 24-year-old primigravid woman with a twin gestation at 35 weeks diagnosed initially with bilateral facial palsy and subsequently with preeclampsia. She then developed partial hemolysis, elevated liver enzymes, and low platelet count syndrome, prompting the diagnosis of severe preeclampsia, and was delivered. Bilateral facial palsy is a rare entity in pregnancy that may be the first sign of preeclampsia and suggests increased severity of disease, warranting close monitoring.

Although several clinical and biological markers of preeclampsia have been evaluated, they have proven to be ineffective in providing a definitive diagnosis during the various stages of the disorder. Exosomes have emerged as ideal biomarkers of pathological states, such as cancer, and have more recently gained interest in pregnancy-related complications, due to their role in cellular communication in normal and complicated pregnancies. This occurs as a result of the specific placenta-derived exosomal molecular cargo, which may be involved in normal pregnancy-associated immunological events, such as the maintenance of maternal–fetal tolerance. This review provides perspectives on placenta-derived exosomes as possible biomarkers for the diagnosis/prognosis of preeclampsia. Using keywords, online databases were searched to identify relevant publications to review the potential use of placenta-derived exosomes as biomarkers of preeclampsia.

Preeclampsia is a risk factor for the development of peripartum cardiomyopathy (PPCM), but it is unknown whether preeclampsia impacts clinical or left ventricular (LV) functional outcomes. This study sought to assess clinical and functional outcomes in women with PPCM complicated by preeclampsia. This retrospective cohort study included women diagnosed with PPCM delivering at Barnes-Jewish Hospital between 2004 to 2014. The primary outcome was one-year event-free survival rate for the combined end point of death and hospital readmission. The secondary outcome was recovery of LV ejection fraction. Seventeen of 39 women (44%) with PPCM had preeclampsia. The groups had similar mean LV ejection fraction at diagnosis (29.6 with versus 27.3 without preeclampsia; P =0.5). Women with preeclampsia had smaller mean LV end-diastolic diameters (5.2 versus 6.0 cm; P =0.001), greater relative wall thickness (0.41 versus 0.35 mm Hg; P =0.009), and lower incidence of eccentric remodeling (12% versus 48%; P =0.03). Clinical follow-up was available for 32 women; 5 died of cardiovascular complications within 1 year of diagnosis (4/15 with versus 1/17 without preeclampsia; P =0.16). In time to event analysis, patients with preeclampsia had worse event-free survival during 1-year follow-up ( P =0.047). Echocardiographic follow-up was available in 10 survivors with and 16 without preeclampsia. LV ejection fraction recovered in 80% of survivors with versus 25% without preeclampsia ( P =0.014). PPCM with concomitant preeclampsia is associated with increased morbidity and mortality and different patterns of LV remodeling and recovery of LV function when compared with patients with PPCM that is not complicated by preeclampsia. © 2017 American Heart Association, Inc.

There are analyzed some of the main aspects related to the causality of preeclampsia, privileging two types of models: the clinic model and the epidemiologic model, first one represented by the hypothesis of the reduced placental perfusion and the second one considering the epidemiologic findings related to the high levels of psychosocial stress and its association with preeclampsia. It is reasoned out the relevance of raising the causality of the disease from an interdisciplinary perspective, integrating the valuable information generated from both types, clinical and epidemiologic, and finally a tentative explanatory model of preeclampsia is proposed, the subclinical and sociocultural aspects that predispose and trigger the disease are emphasized making aspects to stand out: the importance of reduced placental perfusion as an indicator of individual risk, and the high levels of physiological stress, as a result of the unfavorable conditions of the psychosocial surroundings (indicator of population risk) of the pregnant women.

Ghrelin, an endogenous for the growth hormone secretagogue receptor, has been shown to participate in blood pressure regulation. Obestatin, encoded by the same gene as ghrelin, is described as a physiological opponent of ghrelin. We hypothesized that ghrelin/obestatin imbalance played a role in the pathogenesis. This study was designed to determine the alterations of ghrelin and obestatin concentrations and ghrelin/obestatin ratio in maternal serum in preeclampsia. This retrospective case-control study included 31 preeclampsia and 31 gestational week-matched normal pregnancies. Ghrelin and obestatin concentrations in maternal serum were determined by radioimmunoassay, and the ghrelin/obestatin ratio was calculated. The ghrelin concentration and ghrelin/obestatin ratio in maternal serum were significantly lower in preeclampsia than in normal pregnancies (214.34±14.27pg/mL vs 251.49±16.15pg/mL, P=0.041, 1.07±0.09 vs 0.82±0.08, P=0.023). The obestatin concentration in maternal serum was significantly higher in preeclampsia than in normal pregnancies (276.35±15.38pg/mL vs 223.53±18.61pg/mL, P=0.019). The systolic blood pressure in preeclampsia was negatively correlated with ghrelin concentration and ghrelin/obestatin ratio (r=-0.549, P=0.003; r=-0.491, P=0.004) and was positively correlated with obestatin concentrations in preeclampsia (r=0.388, P=0.013). The findings of this study suggested disturbance of ghrelin and obestatin in maternal serum in preeclampsia, and ghrelin/obestatin imbalance might play a role in the pathogenesis of preeclampsia.

A growing body of evidence suggests that complement dysregulation plays a role in the pathogenesis of preeclampsia. The kidney is one of the major organs affected in preeclampsia. Because the kidney is highly susceptible to complement activation, we hypothesized that preeclampsia is associated with renal complement activation. We performed a nationwide search for renal autopsy material in the Netherlands using a computerized database (PALGA). Renal tissue was obtained from 11 women with preeclampsia, 25 pregnant controls, and 14 nonpregnant controls with hypertension. The samples were immunostained for C4d, C1q, mannose-binding lectin, properdin, C3d, C5b-9, IgA, IgG, and IgM. Preeclampsia was significantly associated with renal C4d-a stable marker of complement activation-and the classical pathway marker C1q. In addition, the prevalence of IgM was significantly higher in the kidneys of the preeclamptic women. No other complement markers studied differed between the groups. Our findings in human samples were validated using a soluble fms-like tyrosine kinase 1 mouse model of preeclampsia. The kidneys in the soluble fms-like tyrosine kinase 1-injected mice had significantly more C4 deposits than the control mice. The association between preeclampsia and renal C4d, C1q, and IgM levels suggests that the classical complement pathway is involved in the renal injury in preeclampsia. Moreover, our finding that soluble fms-like tyrosine kinase 1-injected mice develop excess C4 deposits indicates that angiogenic dysregulation may play a role in complement activation within the kidney. We suggest that inhibiting complement activation may be beneficial for preventing the renal manifestations of preeclampsia. © 2015 American Heart Association, Inc.

Therapeutically targeting mitochondrial redox signalling alleviates endothelial dysfunction in preeclampsia.

Science.gov (United States)

McCarthy, Cathal; Kenny, Louise C

2016-09-08

Aberrant placentation generating placental oxidative stress is proposed to play a critical role in the pathophysiology of preeclampsia. Unfortunately, therapeutic trials of antioxidants have been uniformly disappointing. There is provisional evidence implicating mitochondrial dysfunction as a source of oxidative stress in preeclampsia. Here we provide evidence that mitochondrial reactive oxygen species mediates endothelial dysfunction and establish that directly targeting mitochondrial scavenging may provide a protective role. Human umbilical vein endothelial cells exposed to 3% plasma from women with pregnancies complicated by preeclampsia resulted in a significant decrease in mitochondrial function with a subsequent significant increase in mitochondrial superoxide generation compared to cells exposed to plasma from women with uncomplicated pregnancies. Real-time PCR analysis showed increased expression of inflammatory markers TNF-α, TLR-9 and ICAM-1 respectively in endothelial cells treated with preeclampsia plasma. MitoTempo is a mitochondrial-targeted antioxidant, pre-treatment of cells with MitoTempo protected against hydrogen peroxide-induced cell death. Furthermore MitoTempo significantly reduced mitochondrial superoxide production in cells exposed to preeclampsia plasma by normalising mitochondrial metabolism. MitoTempo significantly altered the inflammatory profile of plasma treated cells. These novel data support a functional role for mitochondrial redox signaling in modulating the pathogenesis of preeclampsia and identifies mitochondrial-targeted antioxidants as potential therapeutic candidates.

Records were searched for indicators of pre-eclampsia. Of those who experienced pre-eclampsia and of a random sample of 150 women who did not, the following information on cardiovascular risk factor management after pregnancy was extracted from the records: frequency and timing of blood pressure, cholesterol and glucose measurements - and vascular diagnoses. Additionally the sensitivity and specificity of ICPC coding for pre-eclampsia were determined. Results 35 women experienced pre-eclampsia. Blood pressure was more often checked after pregnancy in these women than in controls (57.1% vs. 12.0%, p Conclusion Despite the evidence of increased risk of future cardiovascular disease in women with a history of pre-eclampsia, follow-up of these women is insufficient and undeveloped in primary care in the Netherlands.

Pre-eclampsia is a pregnancy complication affecting both mother and fetus. Although there is no proven effective method to prevent pre-eclampsia, early identification of women at risk of pre-eclampsia could enhance appropriate application of antenatal care, management and treatment. Very little is known about the cost effectiveness of these and other tests for pre-eclampsia, mainly because there is no clear treatment path. The aim of this study was to provide a comprehensive overview of the existing evidence on the health economics of screening, diagnosis and treatment options in pre-eclampsia. We searched three electronic databases (PubMed, EMBASE and the Cochrane Library) for studies on screening, diagnosis, treatment or prevention of pre-eclampsia, published between 1994 and 2014. Only full papers written in English containing complete economic assessments in pre-eclampsia were included. From an initial total of 138 references, six papers fulfilled the inclusion criteria. Three studies were on the cost effectiveness of treatment of pre-eclampsia, two of which evaluated magnesium sulphate for prevention of seizures and the third evaluated the cost effectiveness of induction of labour versus expectant monitoring. The other three studies were aimed at screening and diagnosis, in combination with subsequent preventive measures. The two studies on magnesium sulphate were equivocal on the cost effectiveness in non-severe cases, and the other study suggested that induction of labour in term pre-eclampsia was more cost effective than expectant monitoring. The screening studies were quite diverse in their objectives as well as in their conclusions. One study concluded that screening is probably not worthwhile, while two other studies stated that in certain scenarios it may be cost effective to screen all pregnant women and prophylactically treat those who are found to be at high risk of developing pre-eclampsia. This study is the first to provide a comprehensive overview

The US Preventive Services Task Force recommends low-dose aspirin for the prevention of preeclampsia among women at high risk for primary occurrence or recurrence of disease. Recommendations for the use of aspirin for preeclampsia prevention were issued by the US Preventive Services Task Force in September 2014. The objective of the study was to evaluate the incidence of recurrent preeclampsia in our cohort before and after the US Preventive Services Task Force recommendation for aspirin for preeclampsia prevention. This was a retrospective cohort study designed to evaluate the rates of recurrent preeclampsia among women with a history of preeclampsia. We utilized a 2-hospital, single academic institution database from August 2011 through June 2016. We excluded multiple gestations and included only the first delivery for women with multiple deliveries during the study period. The cohort of women with a history of preeclampsia were divided into 2 groups, before and after the release of the US Preventive Services Task Force 2014 recommendations. Potential confounders were accounted for in multivariate analyses, and relative risk and adjusted relative risk were calculated. A total of 17,256 deliveries occurred during the study period. A total of 417 women had a documented history of prior preeclampsia: 284 women before and 133 women after the US Preventive Services Task Force recommendation. Comparing the before and after groups, the proportion of Hispanic women in the after group was lower and the method of payment differed between the groups (P .05]). Risk factors for recurrent preeclampsia included maternal age >35 years (relative risk, 1.83; 95% confidence interval, 1.34-2.48), Medicaid insurance (relative risk, 2.08; 95% confidence interval, 1.15-3.78), type 2 diabetes (relative risk, 2.13; 95% confidence interval, 1.37-3.33), and chronic hypertension (relative risk, 1.96; 95% confidence interval, 1.44-2.66). The risk of recurrent preeclampsia was decreased by

Full Text Available Background: Circulating endothelial cells (CECs and E-selectin are known as sensitive and specific markers of en-dothelial dysfunction. This study investigated whether CECs and E-selectin are surrogate biomarkers of preeclampsia and if measurement of CECs and E-selectin, early in the third trimester, could be a means of predicting preeclampsia. Methods: In this prospective, descriptive-analytic study, rollover test was performed on 523 pregnant women during 28-30 weeks of gestation. CECs were measured by anti-CD 146-driven immunomagnetic isolation in women with posi-tive rollover test. They were followed up prospectively until delivery without any active intervention. Women with and without preeclampsia were determined. The number of CECs and level of E-selectin were compared in the two studied groups. Results: From the 47 pregnant women with positive rollover test who were selected and followed up, 22 individuals were diagnosed with preeclampsia while the remainder were normotensive. Mean CEC numbers was significantly high-er in preeclamptic women than normal pregnancies (24.7 cells/mL vs. 13 cells/mL. The best cut-off point for CEC numbers was 6.5 with a sensitivity of 78.9% and a specificity of 69.1%. The level of E-selectin was significantly higher in mothers with preeclampsia (p < 0.05. Conclusions: Higher levels of CECs and E-selectin in women with positive rollover test who developed preeclampsia prior to onset of the complication were predictive of preeclampsia. However, larger studies are needed to confirm these findings.

To assess the association of pre-eclampsia with later cardiovascular death in mothers according to their lifetime number of pregnancies, and particularly after only one child. Prospective, population based cohort study. Medical Birth Registry of Norway. We followed 836,147 Norwegian women with a first singleton birth between 1967 and 2002 for cardiovascular mortality through linkage to the national Cause of Death Registry. About 23,000 women died by 2009, of whom 3891 died from cardiovascular causes. Associations between pre-eclampsia and cardiovascular death were assessed by hazard ratios, estimated by Cox regression analyses. Hazard ratios were adjusted for maternal education (three categories), maternal age at first birth, and year of first birth The rate of cardiovascular mortality among women with preterm pre-eclampsia was 9.2% after having only one child, falling to 1.1% for those with two or more children. With term pre-eclampsia, the rates were 2.8% and 1.1%, respectively. Women with pre-eclampsia in their first pregnancy had higher rates of cardiovascular death than those who did not have the condition at first birth (adjusted hazard ratio 1.6 (95% confidence interval 1.4 to 2.0) after term pre-eclampsia; 3.7 (2.7 to 4.8) after preterm pre-eclampsia). Among women with only one lifetime pregnancy, the increase in risk of cardiovascular death was higher than for those with two or more children (3.4 (2.6 to 4.6) after term pre-eclampsia; 9.4 (6.5 to 13.7) after preterm pre-eclampsia). The risk of cardiovascular death was only moderately elevated among women with pre-eclamptic first pregnancies who went on to have additional children (1.5 (1.2 to 2.0) after term pre-eclampsia; 2.4 (1.5 to 3.9) after preterm pre-eclampsia). There was little evidence of additional risk after recurrent pre-eclampsia. All cause mortality for women with two or more lifetime births, who had pre-eclampsia in first pregnancy, was not elevated, even with preterm pre-eclampsia in first

Full Text Available BACKGROUND Pre-Eclampsia and Eclampsia are the leading causes of maternal and perinatal morbidity and mortality worldwide. In developed countries, much lower incidences have been achieved through aggressive screening and management of Pre-Eclampsia. In developing countries like India, there is a wide gap in quality of health care in cities and rural area. The present study was done to evaluate the incidence of hypertensive disorders and maternal and fetal outcome in a tertiary care centre catering to poor people of Bihar, Bengal and neighboring country, Nepal. MATERIALS AND METHODS This is an observational descriptive study. After obtaining institutional ethical committee approval and informed consent from patients, all the patients presenting to our institution for delivery with Pre-Eclampsia and Eclampsia were included in the study. Socio-economic status, frequency of ANC, age, parity and period of gestation were recorded. Investigations included complete blood count, urinary protein, coagulation profile, liver function tests and kidney function tests. Mode of conduct of delivery and maternal and fetal outcome were thoroughly recorded and described. Data was presented in the form of n (%. RESULTS 64.28% cases with Pre-Eclampsia and 95.12% cases with Eclampsia were from low socio-economic status. 95.12% cases with Eclampsia and 67.5% cases with Pre-Eclampsia had no ANC throughout the pregnancy. Most of the patients were in the age group of 20-25 years. 86.11% cases with Eclampsia and 66.68% with Pre-Eclampsia were primigravida. Most of the patients presented with 37 weeks of gestation. 54.76% Pre-Eclampsia cases and 58.94% Eclampsia delivered by L.S.C.S. Pulmonary edema and acute renal failure were the most common complications. Maternal mortality was 25.60% in Eclampsia cases. The most common cause of maternal mortality was pulmonary edema. Incidence of IUD+ stillbirth was 16.66% in Pre-Eclampsia cases and 34.14% in Eclampsia cases. Overall

Cases were women presented with preeclampsia and healthy pregnant women were the controls. Studied groups were matched for important determinants of HRV. Natural logarithm (Ln of total power (TP, high frequency (HF, low frequency (LF and very low frequency (VLF were used to determine HRV. Normalized low and high frequencies (LF Norm and HF Norm were used to evaluate sympathetic and parasympathetic autonomic modulations respectively.Patients with preeclampsia achieved significantly higher LF Norm [49.80 (16.25 vs. 44.55 (19.15, P = 0.044] and LnLF/HF [0.04 (0.68 vs. -0.28 (0.91, P = 0.023] readings, but lower HF Norm [49.08 (15.29 vs. 55.87 (19.56, P = 0.012], compared with healthy pregnant women. Although all other HRV measurements were higher in the patients with preeclampsia compared with the controls, only LnVLF [4.50 (1.19 vs. 4.01 (1.06, P = 0.017] and LnLF [4.01 (1.58 vs. 3.49 (1.23, P = 0.040] reached statistical significance.The study adds further evidence for the dominant cardiac sympathetic modulations on patients with preeclampsia, probably secondary to parasympathetic withdrawal in this group. However, the higher LnVLF and LnLF readings achieved by preeclamptic women compared with the controls are unexpected in the view that augmented sympathetic modulations usually depresses all HRV parameters including these two measures.

Full Text Available Introduction: Preeclampsia is a pregnancy-specific condition characterized by hypertension and proteinuria. Preeclampsia remains a disease of theories as its real etiology has remained elusive. Endothelial cell dysfunction may play a role in the pathobiology of preeclampsia. There is some evidence to suggest that endothelial cell damage result from oxidative stress. The aim of the study was to measure oxidative stress markers in preeclampsia. Material and Methods: Total antioxidant capacity (TAC, lipid peroxidation (LPO and thiol groups was measured in 20 women with preeclampsia, 20 normal pregnant women and 20 nonpregnant women. All three women groups were matched with respect to age, BMI, parity and gestational age. Oxidative stress markers were measured by spectrophotometer methods. Results: Serum concentration of LPO was significantly higher in preeclampsia (17.7 + 3.8 nmol/ml as compared with nonpregnant women (10.4 + 0.48 nmol/ml, p< 0.0001. TAC in preeclamptic women was lower than those in normal pregnant and non-pregnant women, but not statistically significantly. There was no significant difference between the mean concentrations of thiol groups in the women groups. Conclusion: Increased levels of LPO products may cause peroxidative damage of vascular endothelium and result in clinical symptoms of preeclampsia. However, further experimental and clinical studies are necessary to clarify the pathogenesis of preeclampsia.

Systemic vasoconstriction in preeclamptic patients increases vascular resistance, and is manifested by increased arterial blood flow velocity. The aim of the study is to evaluate if there is a change of Doppler indices in maternal medial cerbral artery (MCA) in severe preeclampsia due to: 1) severity of clinical symptoms, 2) the begining of eclamptic attack and 3) the application of anticonvulsive therapy. A prospective clinical study included 92 pregnant women, gestational age 28-36 weeks. They were divided into three groups: normotensive (n=30), mild preeclampsia (n=33), and severe preeclampsia (n=29). We investigated maternal cerebral circulation by assessing the MCA. We registrated: pulsatility index (Pi), resistance index (Ri), systolic/diastolic ratio (S/D), and the maximum systolic, end diastolic and medium velocity. Patients with severe preeclampsia were divided into two subgroups. subgroup 1 included patients without symptoms of threatening eclampsia (n=18; 62.06%); while subgroup 2 included those with symptoms of preeclampsia (n=11; 37.94%). All patients with severe preeclampsia were treated with magnesium sulfate (MgSO4), and cerebral blood flow was measured before and after the treatment. Statistical analysis was done by oneway ANOVA, Student t-test and t-paired sample test. The difference was considered to be significant if ppreclampsia we found increased velocity values, Pi and Ri, especially in patients with signs of threatened eclampsia, suggesting that blood vessels changes are most prominent in severe preeclampsia. Cerebral blood flow meassurements can be used as a clinical test for the prediction of eclampsia. Magnesium-sulfate (MgSO4) has a signifficant role in prophylaxis and treatment of eclampsia, and, therefore, positive influence on reduction of cerebral ishemic lesions can be expected. We can conclude that changes of the cerebral blood flow can be evaluated by evaluating blood flow velocities in the medial cerebral artery. Velocities tend

To identify if there is a relationship between the deiodinase D2-Thr92Ala genetic variant, thyroid hormone levels and biochemical hypothyroidism in preeclampsia. We genotyped 125 women with preeclampsia and 131 normal pregnant women using PCR-RFLP. Serum thyroid hormone levels were determined using ELISA. Our study showed higher TSH and FT4 levels and lower FT3 levels in women with preeclampsia compared to normal pregnant women, with statistical significance for women with mild and severe preeclampsia. The risk to develop pregnancy-induced hypertension (PIH), mild or severe preeclampsia was increased in carriers of at least one D2-Ala92 allele. TSH and FT4 levels were significantly higher and FT3 levels were significantly lower in preeclamptic women with severe preeclampsia if they carried the D2-Ala92 allele compared to non-carriers. Pregnant women with PIH and mild preeclampsia, carriers of at least one D2-Ala92 allele, delivered at lower gestational age neonates with a lower birth weight compared to non-carriers, but the results were statistically significant only in severe preeclampsia. The D2-Thr92Ala genetic variant is associated with the severity and the obstetric outcome of preeclampsia, and it also influences thyroid hormone levels. The study demonstrates non-thyroidal biochemical hypothyroidism - as a result of deiodination effects due to D2 genotypes.

Several studies point to the placenta as the primary cause of pre-eclampsia. Our objective was to identify placental genes that may contribute to the development of pre-eclampsia. RNA was purified from tissue biopsies from eleven pre-eclamptic placentas and eighteen normal controls. Messenger RNA...... expression from pooled samples was analysed by microarrays. Verification of the expression of selected genes was performed using real-time PCR. A surprisingly low number of genes (21 out of 15,000) were identified as differentially expressed. Among these were genes not previously associated with pre-eclampsia...... as bradykinin B1 receptor and a 14-3-3 protein, but also genes that have already been connected with pre-eclampsia, for example, inhibin beta A subunit and leptin. A low number of genes were repeatedly identified as differentially expressed, because they may represent the endpoint of a cascade of events...

The maternal signs of preeclampsia, which include the new onset of high blood pressure, can occur because of faulty placentation. We theorized that transcriptomic analyses of trophoblast subpopulations in situ would lend new insights into the role of these cells in preeclampsia pathogenesis. Our goal was to enrich syncytiotrophoblasts, invasive cytotrophoblasts, or endovascular cytotrophoblasts from the placentas of severe preeclampsia cases. Total RNA was subjected to global transcriptional profiling to identify RNAs that were misexpressed compared with controls. This was a cross-sectional analysis of placentas from women who had been diagnosed with severe preeclampsia. Gestational age-matched controls were placentas from women who had a preterm birth with no signs of infection. Laser microdissection enabled enrichment of syncytiotrophoblasts, invasive cytotrophoblasts, or endovascular cytotrophoblasts. After RNA isolation, a microarray approach was used for global transcriptional profiling. Immunolocalization identified changes in messenger RNA expression that carried over to the protein level. Differential expression of non-protein-coding RNAs was confirmed by in situ hybridization. A 2-way analysis of variance of non-coding RNA expression identified particular classes that distinguished trophoblasts in cases vs controls. Cajal body foci were visualized by coilin immunolocalization. Comparison of the trophoblast subtype data within each group (severe preeclampsia or noninfected preterm birth) identified many highly differentially expressed genes. They included molecules that are known to be expressed by each subpopulation, which is evidence that the method worked. Genes that were expressed differentially between the 2 groups, in a cell-type-specific manner, encoded a combination of molecules that previous studies associated with severe preeclampsia and those that were not known to be dysregulated in this pregnancy complication.

Full Text Available Objective: The goal of this study was to assess the utility of serum uric acid in preeclampsia diagnosis and its correlation with some maternal and fetal outcomes.Materials and methods: A case-control study was performed on 26 term pregnant women with preeclampsia and 52 normal pregnant women. Serum uric acid, platelet count, hematocrit, gestational age, and birth weight of all patients were measured. Data distribution was assessed with the one sample Kolmogorov-Smirnov test. Mann-Whitney U test was used to assess differences between groups. Correlations between plasma uric acid and other parameters were evaluated with the Spearman’s Rho or Pearson correlation test, where appropriated. Receiver-operating characteristics (ROC curves were used to assess the ability of plasma uric acid to distinguish the preeclampsia from normal subjects. Significance was set at P< 0.05.Results: The mean level of plasma uric acid was 5.8 (+2 mg/dl in cases and 4.9 mg/dl in controls (P=0.04. ROC curve analysis demonstrates the absence of obvious cut off point for plasma uric acid to distinguish preeclampsia. Sensitivity and specificity for uric acid level of 5.5 mg/dl were 61.5% and 78.8%, respectively. There was no significant linear correlation between the plasma uric acid level and other measured parameters in each group.Conclusion: On the basis of our data, the clinical utility of measuring serum uric acid levels in diagnosing preeclampsia is limited.

Comprehensive analysis of preeclampsia-associated DNA methylation in the placenta.

Directory of Open Access Journals (Sweden)

Tianjiao Chu

Full Text Available A small number of recent reports have suggested that altered placental DNA methylation may be associated with early onset preeclampsia. It is important that further studies be undertaken to confirm and develop these findings. We therefore undertook a systematic analysis of DNA methylation patterns in placental tissue from 24 women with preeclampsia and 24 with uncomplicated pregnancy outcome.We analyzed the DNA methylation status of approximately 27,000 CpG sites in placental tissues in a massively parallel fashion using an oligonucleotide microarray. Follow up analysis of DNA methylation at specific CpG loci was performed using the Epityper MassArray approach and high-throughput bisulfite sequencing.Preeclampsia-specific DNA methylation changes were identified in placental tissue samples irrespective of gestational age of delivery. In addition, we identified a group of CpG sites within specific gene sequences that were only altered in early onset-preeclampsia (EOPET although these DNA methylation changes did not correlate with altered mRNA transcription. We found evidence that fetal gender influences DNA methylation at autosomal loci but could find no clear association between DNA methylation and gestational age.Preeclampsia is associated with altered placental DNA methylation. Fetal gender should be carefully considered during the design of future studies in which placental DNA is analyzed at the level of DNA methylation. Further large-scale analyses of preeclampsia-associated DNA methylation are necessary.

Preeclampsia: Reflections on How to Counsel About Preventing Recurrence.

Science.gov (United States)

Costa, Maria Laura

2015-10-01

Preeclampsia is one of the most challenging diseases of pregnancy, with unclear etiology, no specific marker for prediction, and no precise treatment besides delivery of the placenta. Many risk factors have been identified, and diagnostic and management tools have improved in recent years. However, this disease remains one of the leading causes of maternal morbidity and mortality worldwide, especially in under-resourced settings. A history of previous preeclampsia is a known risk factor for a new event in a future pregnancy, with recurrence rates varying from less than 10% to 65%, depending on the population or methodology considered. A recent review that performed an individual participant data meta-analysis on the recurrence of hypertensive disorders of pregnancy in over 99 000 women showed an overall recurrence rate of 20.7%; when specifically considering preeclampsia, it was 13.8%, with milder disease upon recurrence. Prevention of recurrent preeclampsia has been attempted by changes in lifestyle, dietary supplementation, antihypertensive drugs, antithrombotic agents, and others, with much uncertainty about benefit. It is always challenging to treat and counsel a woman with a previous history of preeclampsia; this review will be based on hypothetical clinical cases, using common scenarios in obstetrical practice to consider the available evidence on how to counsel each woman during pre-conception and prenatal consultations.

Full Text Available A partir de la teoría de las representaciones sociales, se realizó una investigación cualitativa con el propósito de comprender las representaciones sociales del proceso salud-enfermedad bucal en madres gestantes de una población urbana. Se entrevistaron 28 mujeres adultas asistentes al programa prenatal en una institución de salud de la ciudad de Medellín. Las entrevistas fueron grabadas y transcritas y se analizaron mediante codificación abierta, axial y selectiva, de acuerdo con la teoría fundada. Los hallazgos revelaron que si bien para las madres gestantes la boca del hijo no ocupa un lugar preponderante al inicio del ciclo vital, gana importancia con el proceso de crecimiento y desarrollo del niño, cuando además de su papel en la masticación y alimentación, adquiere una carga social relevante. El análisis dio cuenta de cómo confluyen en las madres de una población urbana representaciones arraigadas en la tradición, con nuevas visiones en cuya construcción hay elementos de los discursos profesionales y de los medios de comunicación; entre ellas, la estrecha relación salud bucal-dientes, la salud atada a prácticas saludables y a la utilización de servicios de salud y salud bucal como ventaja social, relacionada con la estética.Based on the theory of social representations, a qualitative investigation was conducted in order to assess social representations in oral heath in pregnant mothers living in an urban environment. Twenty-eight pregnant adult women attending a prenatal program at a health institution in the city of Medellín, Colombia, were interviewed. The interviews were recorded and transcribed; analysis was performed through open, axial and selective coding, in line with grounded theory. Findings revealed that although pregnant mothers are not greatly concerned about oral health after birth and in early childhood, it increases in importance during growth and development of the child when, besides chewing and

Full Text Available Introduction: Early diagnosis and prediction of preeclampsia needs appropriate obstetric care. Preeclampsia predicting methods are important. This study was designed to determine the correlation between preeclampsia and quadruple screening test in the nulliparous. Materials and Methods:  This case - control study was conducted on 54 pregnant women with preeclampsia (case group and 108 healthy pregnant women (control group who referred to health centers in Sanandaj, Iran. Ultrasonography was performed to determine the gestational age by a radiologist. Maternal serum levels of alpha fetoprotein (AFP, human chorionic gonadotropin (hCG, unconjugated estriol (uE3, and inhibin-A were measured in the second trimester of pregnancy. Data were analyzed using SPSS statistical software and Chi-square test, T-test, sensitivity, specificity, positive and negative predictive values. Results: The results showed that the sensitivity and specificity for the diagnosis of preeclampsia in pregnant women for hCG were 35.2% and 79.6 respectively. These findings for estriol were 20.4% and 88.9%, for inhibin-A were 38.8% and 88% and for alpha fetoprotein were 38.8% and 74.1%. The positive predictive value for hCG, estriol, inhibin-A and alpha fetoprotein were 46.3%, 47.8%, 61.8% and 42.9% respectively. The negative predictive value for hCG, estriol, inhibin-A and alpha fetoprotein were also 71%, 69.1%, 74.2% and 70.8% respectively. Conclusion: There was a relationship between preeclampsia and high levels of inhibin-A and hCG. Further studies on these markers and evaluating their usefulness in the diagnosis and management of preeclampsia are recommended.

Oocyte donation (OD) is a specific method of artificial reproductive technology that is accompanied by a higher risk of preeclampsia during pregnancy. The pathophysiological mechanism underlying preeclampsia in OD pregnancies is thought to differ from preeclampsia in autologous pregnancies. As preeclampsia in autologous pregnancies is suggested to be associated with complement activation, we studied C4d deposition, circulating complement components and placental complement regulatory proteins in preeclamptic OD pregnancies. Women with uncomplicated and preeclamptic pregnancies after OD or spontaneous conception were selected. We stained the placentas for C4d, marker for complement activation, measured complement factors C1q, C3 and C4 in maternal sera and quantified the placental mRNA expression of complement regulatory proteins CD46, CD55 and CD59. A significantly (p preeclampsia compared with uncomplicated pregnancies, both OD and autologous. The level of complement factors in serum did not differ between the groups. Children born in the autologous preeclampsia group were significantly lower in birth weight (p preeclampsia pregnancies, there is excessive activation of complement in preeclamptic OD pregnancies. However, in contrast to autologous pregnancies this is not associated with counterbalancing upregulation of complement regulatory proteins. Furthermore, C4d deposition in OD pregnancies is not related to the severity of preeclampsia, suggesting another trigger or regulatory mechanism of placental C4d deposition in preeclamptic OD pregnancies.

Soluble Fms-like tyrosine kinase 1 (sFlt-1) is an anti-angiogenic factor released in higher amounts in preeclampsia and implicated in endothelial dysfunction. sFlt-1/PlGF ratio is used in the prediction of preeclampsia. An sFlt-1/PlGF ratio inferior to 38 predicts the short-term absence of preeclampsia. A ratio ? 85 (early-onset PE) or ? 110 (late-onset of PE) could diagnose preeclampsia. In this study, sFlt-1/PlGF ratio has been measured in 183 patients. Sixty-seven preeclampsia have been diagnosed preeclamptic at delivery. The median sFlt-1/PlGF ratio was 100.3. The median ratio among women with preeclampsia (N=67) versus no preeclampsia (N=116) was 212.7 versus 35.4. In accordance with this analysis, an sFlt-1/PlGF ratio ? 38 has a sensibility of 95,5 % and a specificity of 73.3 %. The positive predictive value and the negative predictive value were 67.4 % and 96.6 %, respectively. These results suggest that sFlt-1/PlGF ratio is helpful in the diagnosis of preeclampsia.

Placental dysfunction and oxidative stress contribute to the pathogenesis of preeclampsia, which is a pregnancy-specific disorder. It has been suggested that the incidence of preeclampsia has a seasonal variation. Melatonin, as a seasonal factor, has been suggested to be involved in a successful pregnancy. In this study, we investigated the association of circulating levels of melatonin with preeclampsia. Serum was collected from women with preeclampsia (n=113) and gestation-matched healthy pregnant women, and the levels of melatonin were measured. In addition, the expression of melatonin receptors was examined in preeclamptic placentae (n=27). The association of the incidence of preeclampsia and seasonal variation was also analysed from 1491 women with preeclampsia within 77 745 healthy pregnancies. The serum levels of melatonin were significantly reduced in women with preeclampsia at presentation and these reduced serum levels of melatonin were not associated with the severity or time onset of preeclampsia nor with seasonal variation. The expression of melatonin receptor, MT1 was reduced in preeclamptic placentae. The incidence of preeclampsia was did exhibit seasonal variation, but this was largely due to the increase in the incidence of mild or late-onset preeclampsia. Our results demonstrate that reduced melatonin levels are associated with the development of preeclampsia but that the circulating levels of melatonin do not appear to be subject to seasonal variation during pregnancy.

Full Text Available BACKGROUND: Many epidemiological studies have found a positive association between periodontal disease (PD and the risk of preeclampsia, but the magnitude of this association varies and independent studies have reported conflicting findings. We performed a meta-analysis to ascertain the relationship between PD and preeclampsia. METHODS: The PubMed database was searched up to January 12, 2013, for relevant observational studies on an association between PD and the risk of preeclampsia. Data were extracted and analyzed independently by two authors. The meta-analysis was performed using comprehensive meta-analysis software. RESULTS: Thirteen observational case-control studies and two cohort studies, involving 1089 preeclampsia patients, were identified. Based on a random-effects meta-analysis, a significant association between PD and preeclampsia was identified (odds ratio = 2.79, 95% confidence interval CI, 2.01-3.01, P<0.0001. CONCLUSIONS: Although the causality remains unclear, the association between PD and preeclampsia may reflect the induction of PD by the preeclamptic state, or it may be part of an overall exaggerated inflammatory response to pregnancy. Larger randomized controlled trials with preeclampsia as the primary outcome and pathophysiological studies are required to explore causality and to dissect the biological mechanisms involved.

Full Text Available Urinary podocyte (podocyturia has been studied as a diagnostic marker for preeclampsia. We sought to validate its use in preeclampsia and in differentiating it from other high risk pregnancy states. We studied an obstetric population at high risk to develop preeclampsia (study group and uncomplicated pregnancies (control group by analyzing their urine sediment for podocytes within 24 hours of delivery. Podocytes were identified by immunohistochemistry using the podocyte-specific protein synaptopodin. Of the 56 patients who were enrolled, 29 patients were diagnosed with preeclampsia, 9 patients had hypertensive conditions such as chronic and gestational hypertension, 6 patients had Type I/II and gestational diabetes mellitus, 3 patients were classified as others, and 9 patients exhibited uncomplicated pregnancies. Podocyturia was identified in 11 out of 29 (38% of patients with preeclampsia/eclampsia, 3 out of 9 (33% with gestational and chronic hypertension, and 3 out of 6 (50% with Type I/II and gestational diabetes mellitus. None of the 9 patients (0% with uncomplicated pregnancies demonstrated podocyturia. The sensitivity and specificity of podocyturia for preeclampsia were found to be 38% and 70%. Our study showed that podocyturia does not appear to be a sensitive nor a specific marker to diagnose preeclampsia.

Full Text Available The precise etiology of preeclampsia is unknown. Family studies indicate that both genetic and environmental factors influence its development. One of these factors is NFkB, whose activation depends on NEMO (NFkB essential modulator. This is the first study to investigate the association between the existence of single nucleotide variant of the NEMO gene and the appearance of preeclampsia. A total of 151 women (72 preeclamptic women and 79 controls and their children were examined. Sanger sequencing was performed to identify variants in the NEMO gene in the preeclamptic mothers. The maternal identified variants were then sought in the studied groups of children, and in the maternal and child controls, using RFLP-PCR. Real-time RT-PCR was performed to assess NEMO gene expression in maternal blood, umbilical cord blood and placentas. The sequencing process indicated the existence of two different variants in the 3'UTR region of the NEMO gene of preeclamptic women (IKBKG:c.*368C>A and IKBKG:c.*402C>T. The simultaneous occurrence of the TT genotype in the mother and the TT genotype in the daughter or a T allele in the son increased the risk of preeclampsia development 2.59 fold. Additionally, we found that the configuration of maternal/fetal genotypes (maternal TT/ daughter TT or maternal TT/son T of IKBKG:c.*402C/T variant is associated with the level of NEMO gene expression. Our results showed that, the simultaneous occurrence of the maternal TT genotype (IKBKG:c.*402C>T variants and TT genotype in the daughter or T allele in the son correlates with the level of NEMO gene expression and increases the risk of preeclampsia development. Our observations may offer a new insight into the genetic etiology and pathogenesis of preeclampsia.

Full Text Available Aim: The purpose of this study was to investigate the association between maternal-fetal outcomes and the severity of preeclampsia. Material and Method: A total of 528 singleton pregnancies diagnosed with preeclampsia, severe preeclampsia or HELLP syndrome with pregnancies >24 weeks of gestation were retrospectively evaluated. For each patient, maternal age, gravidity, previous obstetric history, family history, gestational age at the time of hospitalization, systolic and diastolic blood pressures, presence of severe preeclampsia symptoms, laboratory values, dexamethasone use for the treatment of thrombocytopenia, route of delivery, maternal and perinatal outcomes were recorded. Results: Within the study period, the occurences of preeclampsia, HELLP syndrome and severe preeclampsia were 1.4%, 0.12% and 0.57%, respectively. In patients with HELLP syndrome, cesarean delivery rate, blood product transfusion, acute renal failure, liver function tests, D-dimer levels, neonatal respiratory distress syndrome (RDS, necrotizing enterocolitis (NEC, preterm retinopathy, pulmonary hemorrhage and sepsis occurrences, were significantly higher than in patients with mild and severe preeclampsia. On the contrary, platelet counts were significantly lower . In patients with mild preeclampsia, gestational age at the time of delivery, vaginal delivery rate, 1 and 5 minute APGAR score and newborn birthweight were significantly higher when compared to patients with severe preeclampsia or HELLP syndrome. In contrast, systolic and diastolic blood pressures, neonatal intensive care unit admission rate, hospital stay, protein levels in 24 hr urine, and maternal hemoglobin levels were significantly lower in this group. Discussion: In the present study, it was found that HELLP syndrome was more frequently associated with maternal complications and neonatal morbidities. For the prevention of morbidities due to these unpredictable syndromes with unclear etiologies

A case-control study was conducted at Omdurman Maternity Tertiary Hospital, Sudan, during the period from May to August 2014 to investigate AMH level in women with preeclampsia compared to healthy controls. The cases were women with preeclampsia and healthy pregnant women were the controls. The obstetrics and medical history was gathered using a questionnaire. AMH level was measured using ELISA. There was no significant difference between the two groups (40 in each arm of the study) in the age, parity and gestational age. Thirty-three of the 40 cases were patients with severe preeclampsia. There was no significant difference in median inter-quartile of the AMH level between the women with preeclampsia and the controls [0.700 (0.225-1.500) vs. 0.700 (0.400-1.275) ng/ml, P = 0.967]. In a linear regression model there was no association between the log of AMH and age, parity, gestational age, BMI, hemoglobin level and preeclampsia.

Defective nitric oxide synthesis and nitric oxide-mediated vasodilatation is widely documented in the pathophysiology of preeclampsia, a leading cause of maternal and perinatal morbidity and mortality worldwide. Several studies demonstrated the beneficial role of nitric oxide agents, especially glyceryl trinitrate and L-arginine in reducing the blood pressure and improving the uteroplacental blood flow velocities. However, there is insufficient evidence on the efficacy and safety of these agents in the prevention of preeclampsia and its complications, as there are very few randomized controlled trials with small number of women. The aim of this review is to summarize and evaluate the role of nitrates in the prevention of preeclampsia based on the available evidence in the literature till date and suggestions for future research. Supplementation with L-arginine and antioxidant vitamins reduced the incidence of preeclampsia in women at high risk of preeclampsia [P nitrates are needed in high-risk women to validate these findings.

Preeclampsia is a relatively common complication of pregnancy and considered to be associated with different degrees of coagulation dysfunction. This study was developed to evaluate the potential value of coagulation parameters for suggesting preeclampsia during the third trimester of pregnancy. Data from 188 healthy pregnant women, 125 patients with preeclampsia in the third trimester and 120 age-matched nonpregnant women were analyzed. Prothrombin time, prothrombin activity, activated partial thromboplastin time, fibrinogen (Fg), antithrombin, platelet count, mean platelet volume, platelet distribution width and plateletcrit were tested. All parameters, excluding prothrombin time, platelet distribution width and plateletcrit, differed significantly between healthy pregnant women and those with preeclampsia. Platelet count, antithrombin and Fg were significantly lower and mean platelet volume and prothrombin activity were significantly higher in patients with preeclampsia (P preeclampsia was 0.872 for Fg with an optimal cutoff value of ≤2.87g/L (sensitivity = 0.68 and specificity = 0.98). For severe preeclampsia, the area under the curve for Fg reached up to 0.922 with the same optimal cutoff value (sensitivity = 0.84, specificity = 0.98, positive predictive value = 0.96 and negative predictive value = 0.93). Fg is a biomarker suggestive of preeclampsia in the third trimester of pregnancy, and our data provide a potential cutoff value of Fg ≤ 2.87g/L for screening preeclampsia, especially severe preeclampsia.

Preeclampsia is a pregnancy-specific disorder resulting in hypertension and multiorgan dysfunction. There is growing evidence that these effects persist after pregnancy. We aimed to systematically evaluate and quantify the evidence on the relationship between preeclampsia and the future risk of cardiovascular diseases. We studied the future risk of heart failure, coronary heart disease, composite cardiovascular disease, death because of coronary heart or cardiovascular disease, stroke, and stroke death after preeclampsia. A systematic search of MEDLINE and EMBASE was performed to identify relevant studies. We used random-effects meta-analysis to determine the risk. Twenty-two studies were identified with >6.4 million women including >258 000 women with preeclampsia. Meta-analysis of studies that adjusted for potential confounders demonstrated that preeclampsia was independently associated with an increased risk of future heart failure (risk ratio [RR], 4.19; 95% confidence interval [CI], 2.09-8.38), coronary heart disease (RR, 2.50; 95% CI, 1.43-4.37), cardiovascular disease death (RR, 2.21; 95% CI, 1.83-2.66), and stroke (RR, 1.81; 95% CI, 1.29-2.55). Sensitivity analyses showed that preeclampsia continued to be associated with an increased risk of future coronary heart disease, heart failure, and stroke after adjusting for age (RR, 3.89; 95% CI, 1.83-8.26), body mass index (RR, 3.16; 95% CI, 1.41-7.07), and diabetes mellitus (RR, 4.19; 95% CI, 2.09-8.38). Preeclampsia is associated with a 4-fold increase in future incident heart failure and a 2-fold increased risk in coronary heart disease, stroke, and death because of coronary heart or cardiovascular disease. Our study highlights the importance of lifelong monitoring of cardiovascular risk factors in women with a history of preeclampsia. © 2017 American Heart Association, Inc.

The impact of ambient air pollution on pregnant women is a concern in China. However, little is known about the association between air pollution and preeclampsia and the potential modifying effects of meteorological conditions have not been assessed. This study aimed to assess the effects of prenatal exposure to air pollution on preeclampsia, and to explore whether temperature and humidity modify the effects. We performed a retrospective cohort study based on 1.21 million singleton births from the birth registration system in Shenzhen, China, between 2005 and 2012. Daily average measurements of particulate matter air temperature (T), and dew point (T d ) were collected. Logistic regression models were performed to estimate associations between air pollution and preeclampsia during the first and second trimesters, and during the entire pregnancy. In each time window, we observed a positive gradient of increasing preeclampsia risk with increasing quartiles of PM 10 and SO 2 exposure. When stratified by T and T d in three categories (95th percentile), we found a significant interaction between PM 10 and T d on preeclampsia; the adverse effects of PM 10 increased with T d . During the entire pregnancy, there was a null association between PM 10 and preeclampsia under T d   95th percentile. We also found that air pollution effects on preeclampsia in autumn/winter seasons were stronger than those in the spring/summer. This is the first study to address modifying effects of meteorological factors on the association between air pollution and preeclampsia. Findings indicate that prenatal exposure to PM 10 and SO 2 increase preeclampsia risk in Shenzhen, China, and the effects could be modified by humidity. Pregnant women should limit air pollution exposure, particularly during humid periods. Copyright © 2018 Elsevier Ltd. All rights reserved.

Preeclampsia is a major cause of perinatal morbidity and mortality. First-trimester screening has been shown to be effective in selecting patients at an increased risk for preeclampsia in some studies. We sought to evaluate the feasibility of screening for preeclampsia in the first trimester based on maternal characteristics, medical history, biomarkers, and placental volume. This is a prospective observational nonintervention cohort study in an unselected US population. Patients who presented for an ultrasound examination between 11-13+6 weeks' gestation were included. The following parameters were assessed and were used to calculate the risk of preeclampsia: maternal characteristics (demographic, anthropometric, and medical history), maternal biomarkers (mean arterial pressure, uterine artery pulsatility index, placental growth factor, pregnancy-associated plasma protein A, and maternal serum alpha-fetoprotein), and estimated placental volume. After delivery, medical records were searched for the diagnosis of preeclampsia. Detection rates for early-onset preeclampsia (preeclampsia (≥34 weeks' gestation) for 5% and 10% false-positive rates using various combinations of markers were calculated. We screened 1288 patients of whom 1068 (82.99%) were available for analysis. In all, 46 (4.3%) developed preeclampsia, with 13 (1.22%) having early-onset preeclampsia and 33 (3.09%) having late-onset preeclampsia. Using maternal characteristics, serum biomarkers, and uterine artery pulsatility index, the detection rate of early-onset preeclampsia for either 5% or 10% false-positive rate was 85%. With the same protocol, the detection rates for preeclampsia with delivery preeclampsia were 15% and 48% for 5% and 10%, while for preeclampsia at ≥37 weeks' gestation the detection rates were 24% and 43%, respectively. The detection rates for late-onset preeclampsia and preeclampsia with delivery at >37 weeks' gestation were not improved by the addition of biomarkers. Screening

Conservative treatment in severe preeclampsia has been documented by several authors citing significant improvement in neonatal outcome lacking a significant increase in maternal complications. Our objective was to inform of our preliminary results using protocolized conservative management in women with preeclampsia-eclampsia, favoring better neonate conditions. We included 34 patients with average age of 28.2 years with documented severe preeclampsia-eclampsia complicating a 36-weeks or less pregnancy, admitted in the obstetric intensive care unit (OICU) between October 2001 and February 2002. Patients received protocolized management consisting of intravascular colume expansion, anti-hypertensive control, target organ protection, monitoring, and clinical observation. We considered conservative management as a 24 or more period offered to patients with satisfactory response to medical treatment and no evidence of binomial compromise. Of our group, 85% corresponded to severe preeclampsia, 9% to eclampsia, 3% to imminence of eclampsia, and 3% to HELLP syndrome. Average stay in OICU was 5.5 days with 3.5 days average management before pregnancy was interrupted. These patients presented mean gestational age of 32.8 weeks during which we observed anemia, low platelets, D dimmer increments, MAP average of 112.8, PCOc 18.6, and BI 0.15. We obtained 36 live newborns of whom 12% four died, two were extremely immatures (510 g and 600 g, respectively); one 980-g newborn presented intraventricular hemorrhage, and a 1,450-g newborn had multiple organ failure. Conservative treatment in patients with severe preeclampsia-eclampsia is a feasible alternative in hospitals with an ICU. Conservative management can improve neonatal survival and prognosis in preterm newborns.

To study whether human chorionic gonadotropin concentrations during pregnancy or combinations of human chorionic gonadotropin and other angiogenic factors, soluble fms-like tyrosine kinase 1 and placental growth factor (PlGF), are associated with preeclampsia risk. Nested case-control study. Population cohort of pregnant women. A total of 121 cases of preterm (cases of term preeclampsia (≥37 weeks of gestation) and 356 women without preeclampsia (controls). Women with preeclampsia were identified by linkage to the Medical Birth Registry of Norway. Concentrations of human chorionic gonadotropin, soluble fms-like tyrosine kinase 1 and PlGF were measured in maternal serum samples collected in each trimester of pregnancy. Odds ratios of preterm and term preeclampsia. High human chorionic gonadotropin concentrations (highest quartile) in the first trimester were associated with reduced risk for preterm preeclampsia (OR 0.3, 95% CI 0.1-0.9), compared with low human chorionic gonadotropin (lowest quartile), whereas high human chorionic gonadotropin concentrations in the second trimester were associated with increased risk for preterm preeclampsia (OR 4.0, 95% CI 1.8-8.9). High human chorionic gonadotropin concentrations in the third trimester were associated with increased risk for term preeclampsia (OR 4.8, 95% CI 1.8-13.3). Concentrations of human chorionic gonadotropin above the median value combined with PlGF below the median in the second trimester were associated with very high risk for preterm preeclampsia (OR 36.9, 95% CI 8.2-165.8). The results suggest an important role of human chorionic gonadotropin in the pathophysiological processes that lead to preeclampsia. The combined association of human chorionic gonadotropin and PlGF indicates a possible synergism between underlying biological pathways. © 2014 Nordic Federation of Societies of Obstetrics and Gynecology.

Patients with preeclampsia have higher circulating asymmetric dimethylarginine (ADMA). However, whether circulating ADMA is elevated before the diagnosis of preeclampsia has not been determined. A meta-analysis of observational studies that reported circulating ADMA level before the onset of preeclampsia was performed. Pubmed and Embase were searched. Standardized mean differences (SMD) with 95% confidence intervals (CI) were used to estimate the differences in circulating ADMA. A random effect model or a fixed effect model was applied depending on the heterogeneity. The predictive efficacy of circulating ADMA for the incidence of preeclampsia was also explored. Eleven comparisons with 1338 pregnant women were included. The pooled results showed that the circulating ADMA was significantly higher in women who subsequently developed preeclampsia as compared with those did not (SMD: 0.71, p preeclampsia, and retrieved moderate predictive efficacy. Circulating ADMA is elevated before the development of preeclampsia. Studies are needed to evaluate the predictive efficacy of ADMA for the incidence of preeclampsia.

Parece existir uma relação positiva entre o peso pré-gestacional, o ganho de peso da gestante durante a gravidez, e o peso ao nascer do concepto, bem como a idade gestacior.al. Observou-se ainda que houve uma diferença de 296,7 gramas a mais no peso dos recém-nascidos de gestante com peso pré-gestacional adequado, que no grupo de gestante com peso pré-gestacional insuficiente. Em trabalhos anteriores descreveu-se a necessidade de se utilizar curvas ponderais para o diagnóstico do estado nutricional materno: a curva que ora se apresenta é mais simples que outras já descritas anteriormente. No momento está sendo testada para se avaliar a sua eficácia.The authors studied the influence of maternal nutrition on birth weight using anthropometric techniques because these methods are of low cost, and do not need specialized manpower for their application. In the 460 pregnant women attended at a prenatal care service, there was a positive relationship between pre-gestational weight gain during pregnancy, birth weight and gestational age. Babies born from mothers with adequate pre-gestational weight were 296.7 grammes heavier than those of women with insufficient weight. Anthropometric curves for the measurement of maternal weight have been simplified and now this new curve is being tested.

Full Text Available Background: Preeclampsia is a common disorder of pregnancy. Current study was conducted to determine the association of polymorphism in gene of pregnancy-associated plasma protein A (PAPPA and preeclampsia. Methods: In this prospective cohort study, 134 pregnant women were consecutively enrolled and the blood sampling was performed for genetic analysis in a single lab. Then the subjects were followed-up for preeclampsia and it was seen that 34 women developed preeclampsia and the polymorphism of PAPPA gene was compared between those with and without preeclampsia. Results: The results demonstrated that despite twice higher proportion of CC condition of PAPPA in those with preeclampsia in comparison with those with normal pregnancy, there was no significant difference between two groups (P > 0.05. Conclusions: Totally, according to the obtained results, it may be concluded that polymorphism of pregnancy-associated plasma protein A is not related to occurrence of preeclampsia in pregnant women.

Maternal periodontal disease diagnosed by a detailed oral health examination is associated with preeclampsia. Our objective was to measure the association between maternal self-report of oral symptoms/problems, oral hygiene practices, and/or dental service use before or during pregnancy and severe preeclampsia. A written questionnaire was administered to pregnant females at the time of prenatal ultrasound and outcomes were ascertained by chart abstraction. The χ(2) test compared maternal oral symptoms/problems, hygiene practices, and dental service use between females with severe preeclampsia versus normotensive females. Multivariable logistic regression was used to calculate adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for severe preeclampsia. A total of 48 (10%) of 470 females reported ≥2 oral symptoms/problems in the 6 months before pregnancy and 77 (16%) since pregnancy. Fifty-one (11%) reported previous periodontal treatment. Twenty-eight (6%) of 470 developed severe preeclampsia. Females with a history of periodontal treatment were more likely to develop severe preeclampsia (aOR = 3.71; 95% CI = 1.40 to 9.83) than females without a history of periodontal treatment. Self-reported oral health symptoms/problems, oral hygiene practices, or dental service use before or during pregnancy were not associated with severe preeclampsia when considered in the context of other maternal risk factors. Maternal self-report of previous periodontal treatment before pregnancy is associated with severe preeclampsia.

Magnesium sulfate (MgSO4) is used as a prophylaxis for eclamptic seizures. The exact mechanism of action is not fully established. We used phosphorus magnetic resonance spectroscopy (31P-MRS) to investigate if cerebral magnesium (Mg2+) levels differ between women with preeclampsia, normal pregnant, and nonpregnant women. This cross-sectional study comprised 28 women with preeclampsia, 30 women with normal pregnancies in corresponding gestational week (range: 23-41 weeks) and 11 nonpregnant healthy controls. All women underwent 31P-MRS from the parieto-occipital region of the brain and were interviewed about cerebral symptoms. Differences between groups were assessed by analysis of variance and Tukey's post-hoc test. Correlations between Mg2+ levels and specific neurological symptoms were estimated with Spearman's rank test. Mean maternal cerebral Mg2+ levels were lower in women with preeclampsia (0.12 mM ± 0.02) compared to normal pregnant controls (0.14 mM ± 0.03) (P = 0.04). Nonpregnant and normal pregnant women did not differ in Mg2+ levels. Among women with preeclampsia, lower Mg2+ levels correlated with presence of visual disturbances (P = 0.04). Plasma levels of Mg2+ did not differ between preeclampsia and normal pregnancy. Women with preeclampsia have reduced cerebral Mg2+ levels, which could explain the potent antiseizure prophylactic properties of MgSO4. Within the preeclampsia group, women with visual disturbances have lower levels of Mg2+ than those without such symptoms. © American Journal of Hypertension, Ltd 2017. All rights reserved.

Oxidative stress causes biochemical changes in lipids and proteins; these changes can induce damage to the vascular endothelium and create maternal complications that are characteristic of preeclampsia. In this study, we evaluated the oxidative profile of lipoproteins isolated from women with preeclampsia. Thirty women diagnosed with preeclampsia and thirty women without preeclampsia were included in the study. Lipid-damage biomarkers, including conjugated dienes, lipohydroperoxides and malondialdehyde, were measured. The reduction of nitroblue tetrazolium, the formation of dityrosines, and the carbonylation of proteins were assessed as indicators of protein damage. The protective activity of HDL-c was evaluated by the paraoxonase-I activity present on the HDL-c particles. Serum lipid profiles were also quantified in both groups. Data were analysed using Student's t test and the Pearson correlation coefficient. Our results demonstrated in PE women evident oxidative changes in the lipids and proteins in HDL-c and LDL-c particles and the activity of the antioxidant enzyme PON-I decreased 59.9%. HDL-c exhibited self-defence, as demonstrated by the negative correlation between paraoxonase-I activity and the formation of lipohydroperoxides in HDL-c (r = -0.3755, p preeclampsia show oxidative damage to lipids and proteins. We propose an oxidative profile based on the oxidation levels indicated by each of the markers used. We also found that paraoxonase-I is inactivated in the presence of lipohydroperoxides. Antioxidant support might be helpful to reduce oxidative stress in patients with preeclampsia. Further investigations are necessary to define the association between antioxidant activities and preeclampsia.

Multiple cross-sectional studies suggest that there is an association between blood lead and preeclampsia. We performed a systematic review and meta-analysis to summarize information on the association between preeclampsia and lead poisoning. Searches of Medline, Web of Science, Scopus, Pubmed, Science Direct and ProQuest (dissertations and theses) identified 2089 reports, 46 of which were downloaded after reviewing the abstracts, and 11 studies were evaluated as meeting the selection criteria. Evaluation using the ROBINS-I template (Sterne, et al., 2016), indicated moderate risk of bias in all studies. We found that blood lead concentrations were significantly and substantially associated with preeclampsia (k = 12; N = 6069; Cohen's d = 1.26; odds ratio = 9.81; odds ratio LCL = 8.01; odds ratio UCL = 12.02; p = 0.005). Eliminating one study produced a homogeneous meta-analysis and stronger estimates, despite the remaining studies coming from eight separate countries and having countervailing risks of bias. Blood lead concentrations in pregnant women are a major risk factor for preeclampsia, with an increase of 1μg/dL associated with a 1.6% increase in likelihood of preeclampsia, which appears to be the strongest risk factor for preeclampsia yet reported. Pregnant women with historical lead exposure should routinely have blood lead concentrations tested, especially after mid-term. Women with concentrations higher than 5μg/dL should be actively monitored for preeclampsia and be advised to take prophylactic calcium supplementation. All pregnant women should be advised to actively avoid lead exposure. Copyright © 2017 Elsevier Inc. All rights reserved.

Full Text Available As síndromes hipertensivas na gestação merecem especial destaque no cenário da saúde pública mundial. Atualmente, respondem como terceira causa de mortalidade materna no mundo e primeira no Brasil. Do ponto de vista prático, a pré-eclâmpsia continua sendo uma síndrome que leva a graves repercussões maternas e fetais, conhecendo-se ainda pouco sobre sua etiologia. Atualmente, tem-se discutido a melhor terapêutica para os quadros de pré-eclâmpsia em diversos momentos do ciclo gravídico-puerperal, visando sempre à redução de altos índices de morbimortalidade materna e fetal. O parto, considerando-se a fisiopatologia do evento, representa a melhor forma de tratamento. O uso de sulfato de magnésio é recomendado em todos os casos de pré-eclâmpsia grave e eclâmpsia para prevenção e tratamento das crises convulsivas. Da mesma forma, o tratamento dos picos hipertensivos é recomendado. Hidralazina, nifedipina e labetalol têm sido as drogas mais utilizadas com essa finalidade, mas seu uso dependente da familiaridade do médico assistente. A corticoterapia antenatal está indicada sempre que existe risco iminente de prematuridade entre a 24º e 34º semana. Em contrapartida, não há evidências suficientes para recomendar repouso e administração de expansores plasmáticos de rotina, assim como há necessidade urgente de ensaios clínicos randomizados para determinar se o tratamento anti-hipertensivo de manutenção nas gestantes apresenta benefícios ou riscos para mães e fetos, em todas as formas clínicas da doença, em particular nos casos de pré-eclâmpsia pura.Hypertensive disorders in pregnancy deserve special attention in the setting of global public health.

Preeclampsia is a prevalent pregnancy hypertensive disease with both maternal and fetal morbidity and mortality. Emerging evidence indicates that global placental DNA hypomethylation is observed in patients with preeclampsia and is linked to altered gene expression and disease development. However, the molecular basis underlying placental epigenetic changes in preeclampsia remains unclear. Using 2 independent experimental models of preeclampsia, adenosine deaminase-deficient mice and a pathogenic autoantibody-induced mouse model of preeclampsia, we demonstrate that elevated placental adenosine not only induces hallmark features of preeclampsia but also causes placental DNA hypomethylation. The use of genetic approaches to express an adenosine deaminase minigene specifically in placentas, or adenosine deaminase enzyme replacement therapy, restored placental adenosine to normal levels, attenuated preeclampsia features, and abolished placental DNA hypomethylation in adenosine deaminase-deficient mice. Genetic deletion of CD73 (an ectonucleotidase that converts AMP to adenosine) prevented the elevation of placental adenosine in the autoantibody-induced preeclampsia mouse model and ameliorated preeclampsia features and placental DNA hypomethylation. Immunohistochemical studies revealed that elevated placental adenosine-mediated DNA hypomethylation predominantly occurs in spongiotrophoblasts and labyrinthine trophoblasts and that this effect is independent of A2B adenosine receptor activation in both preeclampsia models. Extending our mouse findings to humans, we used cultured human trophoblasts to demonstrate that adenosine functions intracellularly and induces DNA hypomethylation without A2B adenosine receptor activation. Altogether, both mouse and human studies reveal novel mechanisms underlying placental DNA hypomethylation and potential therapeutic approaches for preeclampsia. © 2017 American Heart Association, Inc.

Preeclampsia is a severe pregnancy complication globally, characterized by poor placentation triggering vascular dysfunction. Matrix metalloproteinases (MMPs) exhibit proteolytic activity implicated in the efficiency of trophoblast invasion to the uterine wall, and a dysregulation of these enzymes has been linked to preeclampsia. A decrease in MMP-2 and MMP-9 interferes with the normal remodeling of spiral arteries at early pregnancy stages, leading to the initial pathophysiological changes observed in preeclampsia. Later in pregnancy, an elevation in MMP-2 and MMP-9 induces abnormal release of vasoactive factors conditioning hypertension. Although these two enzymes lead the scene, other MMPs like MMP-1 and MMP-14 seem to have a role in this pathology. This review gathers published recent evidence about the implications of different MMPs in preeclampsia, and the potential use of these enzymes as emergent biomarkers and biological therapeutic targets, focusing on studies involving human subjects.

Objective: To evaluate the hemodynamic changes in mild-moderate preeclampsia using ophthalmic artery Doppler ultrasonography technique. Methods: Ophthalmic artery pulsatility and resistivity indices were calculated in 30 mild-moderate preeclamptic women and 30 normotensive gravid women of matched gestational age. Student's t-test was performed to test the significance of difference. Results: Both indices of peripheral resistance were found to be significantly lower in the ophthalmic arteries of mild-moderately preeclamptic women than those measured in normotensive gravid women at similar stage of pregnancy. In a small number patients whose disease progressed to severe preeclampsia, both indices increased. Conclusion: In patients with mild-moderate preeclampsia, ophthalmic artery color Doppler ultrasonography detects hemodynamic changes that are not present in normotensive gravid women. Reversal of Doppler patterns in a small number of patients with progressive disease supports the hypotheses suggesting the presence of early vasodilation and late vasospasm in the etiology of preeclampsia

Full Text Available BACKGROUND Preeclampsia is a pregnancy specific disorder commonly defined as de novo hypertension and proteinuria after 20 weeks of gestational age. It occurs in 3-5% of pregnancies and is still a major cause of both foetal and maternal morbidity and mortality worldwide. One of the most serious and dreaded complication of preeclampsia is abruptio placentae. Placental separation from its implantation site before delivery of the foetus has been called abruption placentae or accidental haemorrhage. Various studies have shown that there is 2-2.5 fold increase in incidence of abruption in hypertensive disorder of pregnancy. The aim of the study is to study the incidence of abruptio placentae in women with preeclampsia. MATERIALS AND METHODS 100 pregnant women with preeclampsia attending the antenatal OPD as well as admitted to the antenatal ward and labour room fulfilling the inclusion criteria were enrolled in the study. The incidence of abruption placenta among these 100 women was studied. RESULTS Among the 100 women with preeclampsia enrolled in the study, abruptio placentae was noted in 14 women (14%. Maternal complications were seen in the form of anaemia (78.57%, need for blood transfusion (57.14%, shock (28.57%, postpartum haemorrhage (14.28% and puerperal sepsis (7.14%. Perinatal complications were seen in the form of low birth weight (57.14%, prematurity (35.71%, NICU admission (71.43% and intrauterine death (28.57%. CONCLUSION Abruptio placentae affects approximately 1% of all deliveries. However, the incidence significantly increases in cases of preeclampsia and other hypertensive disorders of pregnancy. Association of abruptio placentae in cases of preeclampsia varies from 10-50%. In our study, incidence of abruption placenta in preeclampsia is 14%.

Elevations in circulatory DNA, as measured by real-time PCR, have been observed in pregnancies with manifest preeclampsia. Recent reports have indicated that circulatory nucleosome levels are elevated in the periphery of cancer patients. We have now examined whether circulatory nucleosome levels are similarly elevated in cases with preeclampsia. Maternal plasma samples were prepared from 17 cases with early onset preeclampsia (34 weeks gestation) with 10 matched normotensive controls. Levels of circulatory nucleosomes were quantified by commercial ELISA (enzyme-linked immunosorbant assay). The level of circulatory nucleosomes was significantly elevated in both study preeclampsia groups, compared to the matched normotensive control group (p = 0.000 and p = 0.001, respectively). Our data suggests that preeclampsia is associated with the elevated presence of circulatory nucleosomes, and that this phenomenon occurs in both early- and late-onset forms of the disorder.

Preeclampsia is a pregnancy-specific syndrome that causes substantial maternal and fetal morbidity and mortality. The etiology is incompletely understood, and there is no clinically useful screening test. Current metabolomic technologies have allowed the establishment of metabolic signatures of preeclampsia in early pregnancy. Here, a 2-phase discovery\\/validation metabolic profiling study was performed. In the discovery phase, a nested case-control study was designed, using samples obtained at 15+\\/-1 weeks\\' gestation from 60 women who subsequently developed preeclampsia and 60 controls taking part in the prospective Screening for Pregnancy Endpoints cohort study. Controls were proportionally population matched for age, ethnicity, and body mass index at booking. Plasma samples were analyzed using ultra performance liquid chromatography-mass spectrometry. A multivariate predictive model combining 14 metabolites gave an odds ratio for developing preeclampsia of 36 (95% CI: 12 to 108), with an area under the receiver operator characteristic curve of 0.94. These findings were then validated using an independent case-control study on plasma obtained at 15+\\/-1 weeks from 39 women who subsequently developed preeclampsia and 40 similarly matched controls from a participating center in a different country. The same 14 metabolites produced an odds ratio of 23 (95% CI: 7 to 73) with an area under receiver operator characteristic curve of 0.92. The finding of a consistent discriminatory metabolite signature in early pregnancy plasma preceding the onset of preeclampsia offers insight into disease pathogenesis and offers the tantalizing promise of a robust presymptomatic screening test.

Full Text Available Anatomic and physiological alterations during pregnancy predispose pregnant women to urinary tract infections (UTI. This study aimed to identify the accuracy of the simple urine test for UTI diagnosis in low-risk pregnant women. Diagnostic test performance was conducted in Botucatu, SP, involving 230 pregnant women, between 2006 and 2008. Results showed 10% UTI prevalence. Sensitivity, specificity and accuracy of the simple urine test were 95.6%, 63.3% and 66.5%, respectively, in relation to UTI diagnoses. The analysis of positive (PPV and negative (NPV predictive values showed that, when a regular simple urine test was performed, the chance of UTI occurrence was small (NPV 99.2%. In view of an altered result for such a test, the possibility of UTI existence was small (PPV 22.4%. It was concluded that the accuracy of the simple urine test as a diagnostic means for UTI was low, and that performing a urine culture is essential for appropriate diagnosis.Las alteraciones anatómicas y fisiológicas de la gravidez predisponen a las gestantes a infecciones del tracto urinario (ITU.

Pre-eclampsia (PE) is multisystem and multifactorial complication of pregnancy. The precise cause of pre-eclampsia has not been determined but mal adoption of the rennin and angiotensinogen (AGT) system may play a role. The products of genes involving the components of this system may be potential candidates for pre-eclampsia and hypertension related to pregnancy. This study was designed to determine whether the M235T variants of AGT gene were associated with the prevalence of pre-eclampsia and also to evaluate the role of plasma AGT in the development of the disease. Hence, developed, rapid and reliable PCR based assay was used to screen individuals for the M235T alleles. This assay was also used to genotype prospectively both recruited pregnant women with pre-eclampsia (n=24) and controls (n=11). Plasma AGT was determined by radioimmunoassay (RIA). The results of the PCR based assay revealed a significant association of 235T allele with the prevalence of all pre-eclamptic patients, Chi-square (x2) = 3.714, P 0.05). Also, pre-eclamptic women exhibited significant higher levels of plasma AGT (52.15 ± 1.63) versus controls (44.76 ± 4.6) with P value < 0.001. This gave clear evidence that T235T allele and plasma AGT contributed to the development of pre-eclampsia with pregnancy and correlated with severity of the disease

The aim of this study was to determine the predictive value of the combination of serum angiopoietin-2 (Ang-2) levels and uterine artery Doppler for the detection of preeclampsia in women at 16-18 weeks of gestation and to identify other pregnancy complications that could be predicted with these combined tests. Maternal serum Ang-2 levels were measured, and uterine artery Doppler was performed in 400 pregnant women. The main outcome was preeclampsia. The predictive values of this combination were calculated. Twenty-five women (6.3%) developed preeclampsia. The sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of uterine artery Doppler combined with serum Ang-2 levels for the prediction of preeclampsia were 24.0%, 94.4%, 22.2% and 94.9%, respectively. For the prediction of early-onset preeclampsia, the sensitivity, specificity, PPV and NPV were 57.1%, 94.1%, 14.8% and 99.2%, respectively. Patients with abnormal uterine artery Doppler and abnormal serum Ang-2 levels (above 19.5 ng ml(-1)) were at higher risk for preterm delivery (relative risk=2.7, 95% confidence interval 1.2-5.8). Our findings revealed that the combination of uterine artery Doppler and serum Ang-2 levels at 16-18 weeks of gestation can be used to predict early-onset preeclampsia but not overall preeclampsia. Thus, this combination may be a useful early second trimester screening test for the prediction of early-onset preeclampsia.

Leptin, an adipocyte-derived hormone, plays an important role in reproduction and angiogenesis. Studies examining leptin in preeclampsia are inconsistent, possibly because of small sample sizes and variability in sampling and outcome. We conducted a nested case-control study to examine associations...... between serum leptin (measured: 9-26 weeks gestation) and preeclampsia among 430 primiparous preeclamptic women and 316 primiparous normotensive controls from the Danish National Birth Cohort.

No hubo alteraciones conjuntivales en la segunda muestra (la gestante que presentó anomalías citológicas conjuntivales en la primera muestra, consumía limitadamente alimentos ricos en vitamina A, fue suplementada con el neovitamín II, cuando se tomó la segunda muestra ya había recobrado el patrón normal, lo que demuestra que no existe déficit de vitamina A como problema nutricional en las gestantes de nuestra área de salud en el grupo evaluado. Los resultados del estudio indican que aunque en las encuestas dietéticas se registran moderadas frecuencias de consumo de alimentos ricos en vitamina A, no se detectan deficiencias a nivel de órgano efector, ello posiblemente se deba a que la suma de los aportes alimentarios, más las dosificaciones que tienen los suplementos vitamínicos, satisfacen el nivel de seguridad de mantenimiento de reservas hepáticas, y por lo tanto, proveen la vitamina A más allá del umbral donde aparecen los signos de carencias.A descriptive study of longitudinal prospective character was carried out aimed at establishing the vitamin A status of pregnant women at the "Dr. Joaquín Albarrán" Polyclinic by means of a dietetic survey and a conjunctival impression cytology.

Objective: To evaluate the hemodynamic changes in mild-moderate preeclampsia using ophthalmic artery Doppler ultrasonography technique. Methods: Ophthalmic artery pulsatility and resistivity indices were calculated in 30 mild-moderate preeclamptic women and 30 normotensive gravid women of matched gestational age. Student's t-test was performed to test the significance of difference. Results: Both indices of peripheral resistance were found to be significantly lower in the ophthalmic arteries of mild-moderately preeclamptic women than those measured in normotensive gravid women at similar stage of pregnancy. In a small number patients whose disease progressed to severe preeclampsia, both indices increased. Conclusion: In patients with mild-moderate preeclampsia, ophthalmic artery color Doppler ultrasonography detects hemodynamic changes that are not present in normotensive gravid women. Reversal of Doppler patterns in a small number of patients with progressive disease supports the hypotheses suggesting the presence of early vasodilation and late vasospasm in the etiology of preeclampsia.

Full Text Available Introduction & Objective: Preeclampsia is a disease with worldwide importance to mothers and infants, where it accounts for 20–80% of the strikingly increased maternal mortality. The lack of enzymes added to the homocysteine metabolism or the cofactors necessary for its metabolism (folate, B6 vitamin, B12 vitamin cause hyperhomocysteinemia. Abnormal serum lipid profiles such as cholesterol, LDL, HDL and triglyceride are associated with endothelial dysfunction. Recently high levels of B-HCG have been identified as a potential marker for developing preeclampsia. The purpose of this study was to identify the possible association of homocysteine, vitamin and some serum factors levels with preeclampsia in pregnant women. Materials and Methods: A case control study was performed prospectively on normotensive healthy pregnant women (80 and pregnant women diagnosed with preeclampsia (80 referring to Imam Sadjad hospital in Yasuj, between September 2004 to August 2005. In addition to the obstetric evaluation and laboratory examination in the 3rd trimester of gestation, blood samples were taken from all cases for homocysteine and vitamin B12, folic acid, triglyceride, cholesterol, LDL, HDL, B-HCG analysis. The samples were evaluated by Immunoassay (ELISA. Univariant and logistic regression analyses were used to identify predictors of outcomes. Results: The mean plasma level of total homocysteine was significantly higher in preeclamptic women compared with normal pregnancy(p0.05. Triglyceride and cholesterol levels were significantly higher in preeclamptic women compared with normal pregnant women(p<0/05. LDL and HDL levels were not correlated with preeclampsia. There was no significant association between preeclampsia and B-HCG levels. Conclusion: Homocysteine, triglyceride and cholesterol concentrations increase in preeclampsia but decrease of vitamin B12 and folic acid levels was not observed in preeclampsia. LDL, HDL and B-HCG levels were not

Preeclampsia has been associated with several risk factors and events. However, it still deserves further investigation, considering the multitude of related factors that affect different populations. To evaluate the maternal factors and adverse perinatal outcomes in a cohort of pregnant women with preeclampsia receiving care in the public health network of the city of Maceió. Prospective cohort study carried out in 2014 in the public health network of the city with a sample of pregnant women calculated based on a prevalence of preeclampsia of 17%, confidence level of 90%, power of 80%, and ratio of 1:1. We applied a questionnaire to collect socioeconomic, personal, and anthropometric data, and retrieved perinatal variables from medical records and certificates of live birth. The analysis was performed with Poisson regression and chi-square test considering p values preeclampsia (PWP) and 90 pregnant women without preeclampsia (PWoP). A previous history of preeclampsia (prevalence ratio [PR] = 1.57, 95% confidence interval [95% CI] 1.47 - 1.67, p = 0.000) and black skin color (PR = 1.15, 95% CI 1.00 - 1.33, p = 0.040) were associated with the occurrence of preeclampsia. Among the newborns of PWP and PWoP, respectively, 12.5% and 13.1% (p = 0.907) were small for gestational age and 25.0% and 23.2% (p = 0.994) were large for gestational age. There was a predominance of cesarean delivery. Personal history of preeclampsia and black skin color were associated with the occurrence of preeclampsia. There was a high frequency of birth weight deviations and cesarean deliveries.

Liver X receptor alpha (LXRα) and endoglin have been postulated to play roles in trophoblast invasion and lipid metabolic disturbances. However, the relationship between LXRα and endoglin levels in serum and placenta of patients with preeclampsia remains poorly understood. The objective of this study was to identify correlations between LXRα, endoglin and preeclampsia and provide new feasible methods of clinical prediction and treatment for preeclampsia. We enrolled 45 patients with preeclampsia (24 with moderate preeclampsia and 21 with severe preeclampsia) and 15 normal pregnant women (control group) who were admitted to the Department of Obstetrics of the General Hospital of Beijing Command between October 2012 and July 2013 in this study. Serum and placental LXRα and endoglin levels were analyzed by enzyme-linked immunosorbent assay, real-time quantitative PCR, tissue microarray and immunohistochemistry. Serum and placental LXRα and endoglin levels were significantly higher in patients with preeclampsia than those in control group (Ppreeclampsia displayed significantly higher LXRα and endoglin levels than those with moderate preeclampsia (Ppreeclampsia were positively correlated (serum: r = 0.486, Ppreeclampsia pathogenesis and development and could be used as potential predictors for this disorder.

Full Text Available CONTEXT AND OBJECTIVE Sodium excretion abnormalities in preeclampsia have been studied in relation to several factors. The objective of this study was to compare natriuria (mEq/24 h and calciuria levels (mg/24 h in preeclamptic patients. DESIGN AND SETTING An analytical cross-sectional study with a control group was conducted in the obstetric center and the high-risk pregnancy outpatient clinic at a university hospital in southern Brazil, and in a primary healthcare unit in the same city, including pregnant women with mild preeclampsia, severe preeclampsia or chronic hypertension, and women with normal pregnancies (14 patients in each group. METHOD Natriuria was measured using an ion-selective electrode in an automated clinical chemistry analyzer (Hitache 917, Roche. All the patients collected 24-hour urine, at home or at the hospital, for analysis of proteins, creatinine, calcium, sodium and uric acid. Quantitative variables with asymmetrical distribution were described using the median, minimum and maximum, and were compared using the Kruskal-Wallis test. The results were logarithmically transformed, with one-way analysis of variance (ANOVA by ranks and then the post-hoc Tukey test, and were analyzed by means of the Spearman correlation and receiver operating characteristic (ROC curve. The significance level used was 0.05. RESULTS There were significant differences between the groups in comparing severe preeclampsia with chronic hypertension and severe preeclampsia with controls (P < 0.0001 for both measurements. CONCLUSION Natriuria levels may be lower in preeclampsia when associated with calciuria. Natriuria assessment is an additional test for differential diagnosis of hypertensive diseases in pregnancy, but is a poor predictor when used alone.

Objective: To find the accuracy of uterine artery diastolic notching during the second trimester of pregnancy in predicting pre-eclampsia in primigravida patients. Study Design: Descriptive cross sectional study. Place and Duration of Study: Armed Forces Institute of Radiology and Imaging (AFIRI) Rawalpindi; six months duration from 30 Nov 2012 to 31 May 2013. Material and Methods: This study included 199 primigravida women with singleton pregnancy having diastolic notch in uterine arteries between 20 to 23 weeks of gestation. All patients were examined by both grey scale and doppler ultrasonography. Uterine arteries were evaluated with doppler near the point where they crossed the external iliac arteries. The patient was included in study if the presence of diastolic notch was demonstrated. Clinical follow up in gynae and obs department continued throughout the pregnancy to see if they developed preeclampsia. The data were recorded on a previously prepared proforma and analyzed with SPSS 21. Results: The accuracy of uterine artery doppler ultrasound in identifying women who later developed preeclampsia was 48.24 percent. The frequency of pre-eclampsia with bilateral notch was significantly high in the primigravid of younger age as compare to the primigravid of the older group (p=0.001). The difference in frequency of developing pre-eclampsia with bilateral notch when compared among 20 to 21 week gestational age and 22 to 23 weeks gestational age was statistically insignificant. Conclusion: Uterine artery diastolic notching between 20 and 23 weeks of gestation is an important risk factor for developing pre-eclampsia. This doppler parameter should, therefore, be included in the risk evaluation for gestational hypertension. (author)

Endothelial dysfunction is believed to play a critical role in preeclampsia, however it is unclear whether this dysfunction precedes the pregnancy or is caused by early pathophysiological events. It is also unclear for how long vascular dysfunction may persist post-partum, and whether it represents a mechanism linking preeclampsia with future cardiovascular disease. Our objective was to determine whether women with preeclampsia have worse vascular function compared to women who did not have preeclampsia by performing systematic review and meta-analysis of studies that examined endothelial dysfunction using flow-mediated dilation (FMD). We included studies published before May 29, 2015 that examined FMD before, during and after preeclampsia. Differences in FMD between study groups were evaluated by standardized mean differences. Out of 610 abstracts identified through PubMED, EMBASE and Web of Science, 37 studies were eligible for the meta-analysis. When compared to women who did not have preeclampsia, women who had preeclampsia had lower FMD prior to the development of preeclampsia (~20–29 weeks gestation), at the time of preeclampsia, and for three years post-partum, with the estimated magnitude of the effect ranging between 0.5 and 3 standard deviations. Similar effects were observed when the analysis was limited to studies that excluded women with chronic hypertension, smokers, or both. Vascular dysfunction predates preeclampsia and may contribute to its pathogenesis. Future studies should address whether vascular changes that persist after preeclamptic pregnancies may represent a mechanistic link with the increased risk for future cardiovascular disease.

Full Text Available Pre-eclampsia is a pregnancy disorder of unknown origin. In Norway, pre-eclampsia is reported in 3 to 4 per cent of registered births. At present, November 2014, a series of investigations into the etiology of preeclampsia have been published internationally from the Norwegian Mother and Child Cohort Study (MoBa, and several studies are ongoing. The intention of this paper is to give a short summary of what has been accomplished, and to discuss future avenues of research concerning causes, mechanisms and consequences of pre-eclampsia. The papers that have been published up to now include seven that concern life-styles (physical activity, tobacco and diet, six that include prior pregnancies, infection, gestational weight gain, toxicants and tryptophan metabolism, and two studies concerning issues of selection and validity. Major findings are that tobacco smoking is only associated with reduced risk of pre-eclampsia when it occurs in the last trimester; that processed food and sugar-sweetened beverages are associated with increased risk while vegetables, vitamin D and probiotics are associated with reduced risk; and that prior induced abortions have the same risk-reducing effect as a prior pregnancy. For future studies, we suggest that better use should be made of the family structure built into MoBa. This includes better use of the discordant pregnancy design. A series of ongoing genetic studies, partly in international consortia, will hopefully open new etiological insights. The indications that pre-eclampsia is related to cardiovascular disease and other complex disorders should be further investigated through systematic follow-up of pre-eclamptic women and controls. Finally, MoBa is eminently suited to study the influences that pre-eclampsia can have on the growing child.

Abstract Background Although recent studies have indicated the potential adverse effects of maternal bisphenol A (BPA) exposure on pregnancy such as increasing the risk of pre-eclampsia, epidemiological evidence is limited. We aimed to evaluate the relationship between maternal BPA exposure and the risk of pre-eclampsia. Methods We conducted a nested case–control study among 173 women (74 cases of pre-eclampsia and 99 controls). BPA concentrations were measured using liquid chromatography-mass spectrometry in the maternal serum samples collected during 16–20 gestational weeks. Multivariate logistic models were used to examine the relationship between maternal serum BPA concentrations and the risk of pre-eclampsia. Results BPA was detectable (>0.1 µg/l) in 78.6% of the maternal serum samples at three levels: low (4.44 µg/l). BPA concentrations were significantly higher in the serum samples collected from the pre-eclampsia cases than those from controls (median: 3.40 vs. 1.50 µg/l, P < 0.01). With adjustment for maternal age, primiparous and BMI, the odds of developing pre-eclampsia were significantly elevated in subjects with high serum BPA levels compared with those with low levels (adjusted OR = 16.46, 95%CI = 5.42–49.85) regardless of subcategories of pre-eclampsia including severity and onset time. Among the pre-eclampsia subjects, the maternal serum concentration of BPA was not different between the early- and late-onset subjects (median: 3.09 vs. 3.50 µg/l, P = 0.57), but surprisingly higher in mild pre-eclampsia subjects compared with severe pre-eclampsia subjects (median: 5.20 vs. 1.80 µg/l, P < 0.01). Conclusions These results demonstrated that maternal exposure to high level of BPA could be associated with an increased risk of pre-eclampsia. PMID:29186464

The relationship between urinary tract infection during pregnancy and preeclampsia: causal, confounded or spurious?

Science.gov (United States)

Karmon, Anatte; Sheiner, Eyal

2008-06-01

Preeclampsia is a major cause of maternal morbidity, although its precise etiology remains elusive. A number of studies suggest that urinary tract infection (UTI) during the course of gestation is associated with elevated risk for preeclampsia, while others have failed to prove such an association. In our medical center, pregnant women who were exposed to at least one UTI episode during pregnancy were 1.3 times more likely to have mild preeclampsia and 1.8 times more likely to have severe preeclampsia as compared to unexposed women. Our results are based on univariate analyses and are not adjusted for potential confounders. This editorial aims to discuss the relationship between urinary tract infection and preeclampsia, as well as examine the current problems regarding the interpretation of this association. Although the relationship between UTI and preeclampsia has been demonstrated in studies with various designs, carried-out in a variety of settings, the nature of this association is unclear. By taking into account timeline, dose-response effects, treatment influences, and potential confounders, as well as by neutralizing potential biases, future studies may be able to clarify the relationship between UTI and preeclampsia by determining if it is causal, confounded, or spurious.

Preeclampsia is a leading cause of maternal morbidity and mortality and adverse neonatal outcomes. Little is known about the extent of the health and cost burden of preeclampsia in the United States. This study sought to quantify the annual epidemiological and health care cost burden of preeclampsia to both mothers and infants in the United States in 2012. We used epidemiological and econometric methods to assess the annual cost of preeclampsia in the United States using a combination of population-based and administrative data sets: the National Center for Health Statistics Vital Statistics on Births, the California Perinatal Quality Care Collaborative Databases, the US Health Care Cost and Utilization Project database, and a commercial claims data set. Preeclampsia increased the probability of an adverse event from 4.6% to 10.1% for mothers and from 7.8% to 15.4% for infants while lowering gestational age by 1.7 weeks (P preeclampsia during the first 12 months after birth was $1.03 billion for mothers and $1.15 billion for infants. The cost burden per infant is dependent on gestational age, ranging from $150,000 at 26 weeks gestational age to $1311 at 36 weeks gestational age. In 2012, the cost of preeclampsia within the first 12 months of delivery was $2.18 billion in the United States ($1.03 billion for mothers and $1.15 billion for infants), and was disproportionately borne by births of low gestational age.

The aim of this study was to evaluate the risk of preeclampsia in women of advanced age who conceived through donated oocytes as compared with natural conceptions. A historical prospective study of singleton live births of parturients ≥ 45 years of age at four university hospitals was conducted. For the purpose of the study, the population was divided by the mode of conception into two groups: oocyte donation and natural conception. The main outcome variable in this study was preeclampsia. Secondary outcomes included pregnancy-induced hypertension and Small for Gestational Age. Two hundred and seventy pregnancies were achieved naturally and 135 women conceived by oocyte donation. Mean age at delivery for the natural conception and oocyte donation groups was 45.7 and 47.8, respectively. Preeclampsia complicated 3 out of 270 (1.1%) natural conception pregnancies and 17 out of 135 (12.6%) oocyte donation conceptions. After adjusting for confounders, oocyte donation pregnancies were found to be associated with a 12-fold increased risk for preeclampsia (P = 0.001). Among oocyte donation pregnancies, the risk of preeclampsia was not affected by parity or age. A substantially increased risk for preeclampsia was found in oocyte donation pregnancies, suggesting that the foreign oocyte may play a specific biologic role in the development of preeclampsia after the age of 45.

The aim of present study was to determine the role of matrix metalloproteinase-8 (MMP-8) C-799T (rs11225395) and C+17 (rs2155052) polymorphisms in susceptibility to preeclampsia. In a case-control study, 256 pregnant women including 152 women with preeclampsia (86 women with mild preeclampsia and 66 women with severe preeclampsia) and 104 women with normal pregnancy from Western Iran with Kurdish ethnic background were investigated for MMP-8 C-799T and C + 17G polymorphisms using polymerase chain reaction-restriction fragment length polymorphism method. Comparing the MMP-8 TT genotype with the combined genotype of CC+CT (recessive model) indicated a significantly higher frequency of the MMP-8 TT genotype (47%) in severe preeclamptic patients than that in healthy pregnant women (30.8%) that was associated with 1.99-fold increased risk of severe preeclampsia (95% CI = 1.05-3.77, p = 0.034). The frequency of MMP-8 G allele was 27.3% in all preeclamptic patients compared to 30.2% in controls (p = 0.56). Also, no significant difference was detected comparing the frequency of G allele in mild (26.6%, p = 0.46) and severe preeclamptic patients (28.4%, p = 0.75) with controls (30.2%). Our study demonstrated that the MMP-8 C-799T is associated with the risk of developing severe preeclampsia during pregnancy. However, the MMP-8 C + 17G polymorphism might not be a risk factor for susceptibility to preeclampsia.

Full Text Available Objective: To study the vitamin E levels in preeclampsia placenta tissue and its correlation with oxidative stress injury and apoptosis. Methods: A total of 60 pregnant women with preeclampsia who received treatment and gave birth in our hospital between July 2012 and January 2016 were collected and divided into mild preeclampsia group (n=41 and severe preeclampsia group (n=19 according to the disease severity; 38 normal pregnant women who received pregnancy test and gave birth in our hospital during the same period were selected as healthy control group. The placental tissue samples of three groups of research subjects were retained, high performance liquid chromatograph-mass spectrometry was used to detect VitE levels in tissue grinding fluid, automatic biochemical analyzer was used to detect the levels of oxidative stress injury indexes, and fluorescence quantitative PCR method was used to detect the mRNA expression of apoptosis molecules. Results: VitE, SOD and CAT levels in grinding fluid of severe preeclampsia group were lower than those of mild preeclampsia group and healthy control group while ROS and AOPP levels were higher than those of mild preeclampsia group and healthy control group; Fas, caspase and Apaf-1 mRNA expression were higher than those of mild preeclampsia group and healthy control group while anti-apoptotic molecules Bcl-2, Bcl-xl, Mcl-2 and p57kip2 mRNA expression were lower than those of mild preeclampsia group and healthy control group. Spearman correlation analysis showed that VitE level in the preeclampsia placenta tissue was directly correlated with oxidative stress injury and cell apoptosis. Conclusion: VitE deficiency is the direct factor that results in oxidative stress and cell apoptosis in patients with preeclampsia, and the VitE supplementation in time is expected to become the auxiliary treatment means for patients with preeclampsia.

Full Text Available Abstract Background: Preeclampsia has been associated with several risk factors and events. However, it still deserves further investigation, considering the multitude of related factors that affect different populations. Objective: To evaluate the maternal factors and adverse perinatal outcomes in a cohort of pregnant women with preeclampsia receiving care in the public health network of the city of Maceió. Methods: Prospective cohort study carried out in 2014 in the public health network of the city with a sample of pregnant women calculated based on a prevalence of preeclampsia of 17%, confidence level of 90%, power of 80%, and ratio of 1:1. We applied a questionnaire to collect socioeconomic, personal, and anthropometric data, and retrieved perinatal variables from medical records and certificates of live birth. The analysis was performed with Poisson regression and chi-square test considering p values < 0.05 as significant. Results: We evaluated 90 pregnant women with preeclampsia (PWP and 90 pregnant women without preeclampsia (PWoP.

Gestational diabetes, pre-eclampsia as well as intra-uterine infection during pregnancy affects the function of the endothelium both in the mother and the fetus leading to endothelial dysfunction. Gestational diabetes is also associated with an increased incidence of pre-eclampsia and it is likely that both the hyperglycemia as well as the release of cytokines especially TNFα during hyperglycemia may play an important role in the pathogenesis of endothelial dysfunction leading to preeclampsia. Similarly, some but not all studies have suggested that infection of the mother under certain circumstances can also lead to preeclampsia as women with either a bacterial or viral infection were at a higher risk of developing preeclampsia, compared to women without infection and infection also leads to a release in TNFα. Endothelial cells exposed to either high glucose or TNFα leads to an increase in the production of H2O2 and to a decrease in endothelial cell proliferation. The cellular and molecular mechanisms involved in this phenomenon are discussed.Gestational diabetes, pre-eclampsia as well as intra-uterine infection during pregnancy has profound effects on the fetus and long term effects on the neonate. All three conditions affect the function of the endothelium both in the mother and the fetus leading to endothelial dysfunction. Gestational diabetes is also associated with an increased incidence of pre-eclampsia and it is likely that both the hyperglycemia as well as the release of cytokines especially TNFα during hyperglycemia may play an important role in the pathogenesis of endothelial dysfunction leading to preeclampsia. It has also been suggested although not universally accepted that under certain circumstances maternal infection may also predispose to pre-eclampsia. Pre-eclampsia is also associated with the release of TNFα and endothelial dysfunction. However, the cellular and molecular mechanism(s) leading to the endothelial dysfunction by either

Preeclampsia is a leading cause of maternal and perinatal morbidity and mortality globally and proteinuria can be one of the cardinal features of this disease. However, studies about the association of the amount of proteinuria and the severity of preeclampsia, and perinatal outcomes are limited. Data on 239 women with preeclampsia were retrospectively collected from a university teaching hospital from September 2011 to June 2013 and analysed. Data included all clinical parameters and proteinuria in a 24h urine collection. In cases of severe preeclampsia, significantly fewer patients had proteinuria levels 0.3g/L, but there was no difference in cases of severe preeclampsia when proteinuria levels were >0.3g/L. Furthermore, when proteinuria levels were >0.3g/L, the frequency of severe preeclampsia in each group was significantly higher than the frequency of mild pre-eclampsia cases. Time of onset was significantly earlier in patients with proteinuria >3g/L in a 24h urine collection, but time between the onset of preeclampsia and delivery was not correlated with the amount of proteinuria. The birth weight was significantly lower in patients with proteinuria >3g/L. The incidence of fetal growth restriction or stillbirth was significantly higher in patients with proteinuria >5g/L. Our data demonstrate that the amount of proteinuria is not associated with the severe of preeclampsia, once proteinuria is detected, but is related to the severity of preeclampsia. The adverse fetal outcomes appear to be the function of prematurity rather than proteinuria itself. Copyright © 2017 International Society for the Study of Hypertension in Pregnancy.

Antenatal clinics and wards at St. Thomas' Hospital (London, UK). Forty-five pregnant women including 15 with pre-eclampsia. Nine sequential same arm blood pressure (BP) measurements were taken from each woman by trained observers, alternating between mercury sphygmomanometry and the test device. Grading criteria of the BHS protocol (A/B grade=pass; C/D=fail). The Omron MIT Elite achieved a grade A/A in both pregnancy and pre-eclampsia. The mean difference (SD) between the mercury standard and the device in pregnancy was -1.1 (5.2)mmHg and 1.5 (4.8)mmHg for systolic and diastolic BP respectively compared to 0.2 (5.3)mmHg and 2.2 (5.5)mmHg in pre-eclampsia. The Omron MIT Elite can be recommended for use in pregnancy and pre-eclampsia according to the BHS protocol. To date, this is the most accurate automated BP device validated in pre-eclampsia.

Preeclampsia is a human pregnancy-specific disorder characterized by a placental pro-inflammatory response in combination with an imbalance of angiogenic factors and clinical symptoms, including hypertension and proteinuria. Insufficient uteroplacental oxygenation in preeclampsia due to impaired trophoblast invasion during placentation is believed to be responsible for many of the molecular events leading to the clinical manifestations of this disease. We investigated the use of hypoxic treatment of the dual placental perfusion system as a model for preeclampsia. A modified perfusion technique allowed us to achieve a mean soluble oxygen tension within the intervillous space (IVS) of 5-7% for normoxia and preeclampsia). We assayed for the levels of different inflammatory cytokines, oxidative stress markers, as well as other factors, such as endothelin (ET)-1 that are known to be implicated as part of the inflammatory response in preeclampsia. Our results show a significant increase under hypoxia in the levels of different inflammatory cytokines, including IL-6 (P=0.002), IL-8 (Ppreeclampsia. This would therefore provide a powerful tool for studying and further delineating the molecular mechanisms involved in the underlying pathophysiology of preeclampsia.

Full Text Available Introducción: son universalmente reconocidas las virtudes de la lactancia materna -y es obvio que la mujer está dotada fisiológicamente para el amamantamiento y en un gran número de organizaciones internacionales de salud de diferentes países se han diseñado políticas con el objetivo de promover adecuadamente esta inigualable práctica- pero aún son múltiples los obstáculos que se presentan a su establecimiento exitoso, y los resultados, a largo plazo, no son satisfactorios. Objetivo: evaluar la información que, sobre lactancia materna, poseen las gestantes en el tercer trimestre de su embarazo, que pertenecen al Policlínico "Mártires del 9 de Abril", del municipio San José de las Lajas. Métodos: se realizó un estudio descriptivo, transversal, para conocer el nivel de información sobre lactancia materna, en el tercer trimestre, de 114 gestantes del Policlínico "Mártires del 9 de Abril", de San José de las Lajas. Se valoraron sus historias de salud individual y familiar, y se les aplicó un cuestionario con 22 preguntas que se evaluó cualitativa y cuantitativamente. Resultados: solo la quinta parte de las gestantes poseía la información suficiente sobre lactancia materna, aunque la mayoría había asumido que sí los tenía. Más de la mitad de los 17 aspectos explorados, eran deficientes en más del 50 % de las encuestadas. Los errores más frecuentes fueron: momento de dar agua al niño con lactancia materna exclusiva, cuándo brindar otro alimento, hasta cuándo mantener la lactancia materna, cómo debe ser la dieta de la madre, el alternamiento y el aseo de los pechos, y los impedimentos de la madre para la lactancia. Conclusiones: gran número de gestantes evidencian desconocimientos o actitudes equivocadas de diversa índole en relación con la lactancia materna exclusiva, aunque creen tener dominio del tema. Se deben explorar otros aspectos, además de los conocimientos sobre la lactancia, que, sin duda, atentan

Full Text Available Myasthenia gravis (MG is a rare autoimmune disease that leads to progressive muscle weakness and is common during female reproductive years. The myasthenic mother and her newborn must be observed carefully, as complications during all stages of pregnancy and the puerperium may arise suddenly. Preeclampsia is a common obstetrical condition for which magnesium sulfate is used for seizure prophylaxis. However, magnesium sulfate is strongly contraindicated in MG as it impairs already slowed nerve-muscle connections. Similarly, many first-line antihypertensive medications, including calcium channels blockers and β-blockers, may lead to MG exacerbation. This case describes the effective obstetrical management of a patient with MG who developed severe preeclampsia. The effective use of levetiracetam and various antihypertensive medications including intravenous labetalol is described. A review of the ten reported cases of MG complicated by preeclampsia is examined to aggregate observations of clinical care, with focus on delivery methods, anticonvulsants, and antihypertensive medications.

Full Text Available Background : Low-dose aspirin (LDA is widely used for prevention of preeclampsia. However, conflicting results have been obtained from various studies. Aim: The aim of our study was to evaluate the effect of LDA in prevention of preeclampsia in high-risk and low-risk women. Materials and Methods : A total of 19 randomized control trials were identified using PUBMED search engine and Cochrane Clinical Trial register. The study population was divided into high-risk and low-risk groups. The effect measured was incidence of preeclampsia in women taking either LDA or placebo where the relative risk (RR and the 95% confidence interval (CI were calculated for both groups. Results : A total of 28237 women were studied, out of which 16550 were in the low-risk group while 11687 were in the high-risk group. The overall incidence of preeclampsia was 7.4%. With the aspirin group it was 6.9% while in the placebo group it was 7.8%. In the high-risk group there was 21% reduction in the risk of preeclampsia associated with the use of aspirin (RR 0.79, 95% CI 0.65-0.97. However, LDA is not effective in reducing the risk in low-risk population (RR 0.86, 95% CI 0.64-1.17. Conclusion: LDA has a small effect in the prevention of preeclampsia in women considered to be at high risk for the disease. However, it is not effective in reducing the risk in the low-risk group.

Background Although the exact pathophysiology of preeclampsia is not fully understood, several elemental micronutrient abnormalities have been suggested to play a contributory role in preeclampsia. Aims To investigate the levels of calcium, magnesium, zinc and copper in women with preeclampsia. Subjects and Methods A case—control study was conducted in Omdurman Maternity Hospital, Sudan, during the period of September through December 2014. The cases were women with preeclampsia while healthy pregnant women were the controls. The medical and obstetrics history was gathered using questionnaires. The serum levels of calcium, magnesium, zinc and copper were measured using atomic absorption spectrophotometer. Results There was no significant difference between the two groups in their age, gestational age, parity and body mass index. Zinc and copper levels were not significantly different between the two groups. In comparison with the controls, women with preeclampsia had a significantly lower median (inter-quartile) serum calcium [7.6 (4.0─9.6) vs. 8.1 (10.6─14.2), mg/dl, P = 0.032] and higher levels of magnesium [1.9 (1.4─2.5) vs. 1.4 (1.0─1.9) mg/dl; P = 0.003]. In binary logistic regression, lower calcium (OR = 0.73, 95% CI = 0.56 ─ 0.95, P = 0.021) and higher magnesium (OR = 5.724, 95% CI = 1.23 ─ 26.50, P = 0.026) levels were associated with preeclampsia. There were no significant correlations between levels of hemoglobin and these trace elements. Conclusion The current study showed significant associations between preeclampsia and serum levels of calcium and magnesium. PMID:27911936

Full Text Available Background Pre-eclampsia is a serious hypertensive condition of pregnancy associated with high maternal and fetal morbidity and mortality. Women who have had pre-eclampsia have a greater risk of developing hypertension, stroke and ischemic heart disease in later life. The etiology of pre-eclampsia remains unclear. Placental insufficiency plays a key role in the progression of this disease. The aim of this study was to determine membrane potential, serum calcium and serum selenium levels in preeclampsia subjects in Owerri.   Methods A case control study involving 200 primigravida (100 preeclamptic and 100 apparently healthy between the ages of 20 and 32 years attending General Hospital Owerri. Fasting venous blood was collected for the determination of serum selenium and serum calcium while membrane potential was calculated using the Nernst equation. The serum calcium was estimated using Randox Kit and serum selenium by atomic absorption spectrophotometry. The Independent Student t test was used for statistical analysis.   Results The results revealed that membrane potential and serum selenium as well as serum calcium were significantly decreased in preeclampsia when compared with the controls, at p<0.05.   Conclusion Our study demonstrated that the decrease in membrane potential, serum calcium and serum selenium levels may play a critical role in the pathogenesis of pre-eclampsia. There may be a need for increasing the dietary intake of these essential trace metals during pregnancy to prevent pre-eclampsia in Owerri.

Preeclampsia often complicates pregnancies after maternal kidney transplantation. We aimed to assess whether preeclampsia is associated with kidney function decline either during the pregnancy or in the long term. We performed an international multicenter retrospective cohort study. Renal function at conception, pregnancy outcomes, and short- and long-term graft outcomes were collected for women who were pregnant after renal transplantation and had transplant and obstetric care at the participating centers. In women who had multiple pregnancies during the study period, only the last pregnancy was included. Univariate and multivariable analyses were performed. We retrieved pregnancy outcomes and long-term renal outcomes for 52 women. Chronic hypertension was present at baseline in 27%. Mean estimated glomerular filtration rate (GFR) at start of pregnancy was 52.4±17.5 mL/min/1.73 m. Mean estimated GFR at delivery was 47.6±21.6 mL/min/1.73 m, which was significantly lower than at conception (P=.03). Twenty women (38%) developed preeclampsia. In multivariable analysis, women who developed preeclampsia had a 10.7-mL/min/1.73 m higher drop in estimated GFR between conception and delivery than women who did not develop preeclampsia (P=.02). Long-term estimated GFR follow-up was obtained at a median of 5.8 years (range 1.3-27.5 years). Mean estimated GFR at last follow-up was 38±23 mL/kg/1.73 m. Seventeen women (33%) experienced graft loss over the follow-up period. Incidence of graft loss was similar in women with and without preeclampsia in their last pregnancy (30% and 34%, respectively; P=.99). In multivariable analysis, the decrease in estimated GFR between conception and last follow-up was similar in women who experienced preeclampsia during pregnancy and those who did not (difference -2.69 mL/min/1.73 m, P=.65). Preeclampsia commonly complicates pregnancies after renal transplantation but is not associated with long-term renal dysfunction or graft loss.

The Combined Multimarker Screening and Randomized Patient Treatment with Aspirin for Evidence-Based Preeclampsia Prevention trial demonstrated that in women who were at high risk for preterm preeclampsia with delivery at aspirin administration from 11 to 14 until 36 weeks' gestation was associated with a significant reduction in the incidence of preterm preeclampsia (odds ratio 0.38; 95% confidence interval, 0.20 to 0.74; P=0.004). We sought to examine whether there are differences in the effect of aspirin on the incidence of preterm preeclampsia in the Aspirin for Evidence-Based Preeclampsia Prevention trial in subgroups defined according to maternal characteristics and medical and obstetrical history. This was a secondary analysis of data from the Aspirin for Evidence-Based Preeclampsia Prevention trial. Subgroup analysis was performed to assess evidence of differences in the effect of aspirin on incidence of preterm preeclampsia in subgroups defined by maternal age (aspirin effect in subgroups defined according to maternal characteristics and obstetrical history. In participants with chronic hypertension preterm preeclampsia occurred in 10.2% (5/49) in the aspirin group and 8.2% (5/61) in the placebo group (adjusted odds ratio, 1.29; 95% confidence interval, 0.33-5.12). The respective values in those without chronic hypertension were 1.1% (8/749) in the aspirin group and 3.9% (30/761) in the placebo group (adjusted odds ratio, 0.27; 95% confidence interval, 0.12-0.60). In all participants with adherence of ≥90% the adjusted odds ratio in the aspirin group was 0.24 (95% confidence interval, 0.09-0.65); in the subgroup with chronic hypertension it was 2.06 (95% confidence interval, 0.40-10.71); and in those without chronic hypertension it was 0.05 (95% confidence interval, 0.01-0.41). For the complete data set the test of interaction was not significant at the 5% level (P = .055), but in those with adherence ≥90%, after adjustment for multiple comparisons

Preeclampsia is a hypertensive disorder of pregnancy and is one of the most common causes of poor perinatal outcomes. Preeclampsia increases the risk of hypertension in the future. Variants of WNK1 (lysine deficient protein kinase 1), ADRB2 (β2 adrenergic receptor), NEDD4L (ubiquitin-protein ligase NEDD4-like), KLK1 (kallikrein 1) contribute to hypertension, and AKR1C3 (aldo-keto reductase family1 member C3), is associated with preeclampsia. The association of single nucleotide polymorphisms (SNPs) in these five candidate preeclampsia susceptibility genes and the related traits in Chinese individuals were investigated. In this study, 13 SNPs of the five genes were genotyped in 276 preeclampsia patients and 229 age- and area-matched normal pregnancies in women of Chinese Northern Han origin. The 95% confidence interval (CI) and odds ratio (OR) were estimated by binary logistic regression. No obvious linkage disequilibrium or haplotypes were observed among these SNPs. Those with GG genotype and allele G of AKR1C3 (rs10508293) had a decreased risk of preeclampsia (adjusted OR = 3.011, 95% CI = 1.758-5.159, and adjusted OR = 1.745, 95% CI = 1.349-2.257, respectively). The AA genotype and allele A of WNK1 (rs1468326) were significantly associated with an increased risk in preeclampsia (adjusted OR = 2.307, 95% CI = 1.206-3.443, and adjusted OR = 1.663, 95% CI = 1.283-2.157, respectively). The findings indicate that the GG genotype of AKR1C3 rs10508293 is associated with decreased risk for preeclampsia and the AA genotype of WNK1 rs1468326 are related with an increased risk for preeclampsia.

The objective of this study was to characterize morbidity, acuity, and maternal risks associated with preeclampsia across hospitals with varying obstetric volumes. This retrospective cohort analysis used a large administrative data source, the Perspective database, to characterize the risk for preeclampsia from 2006 to 2015. Hospitals were classified as having either low (≤1000), moderate (1001-2000), or high (≥2000) delivery volume. The primary outcomes included preeclampsia, antihypertensive administration, comorbidity, and related severe maternal morbidity. Severe maternal morbidity was estimated using criteria from the Centers for Disease Control and Prevention. Comorbidity was estimated using an obstetric comorbidity index. Univariable comparisons were made with Chi-squared test. Adjusted log linear regression models were fit to assess factors associated with severe morbidity with risk ratios with 95% confidence intervals as the measures of effect. Population weights were applied to create national estimates. Of 36,985,729 deliveries included, 1,414,484 (3.8%) had a diagnosis of preeclampsia. Of these, 779,511 (2.1%) had mild, 171,109 (0.5%) superimposed, and 463,864 (1.3%) severe preeclampsia. The prevalence of mild, superimposed, and severe preeclampsia each increased over the study period with severe and superimposed preeclampsia as opposed to mild preeclampsia increasing the most proportionately (53.2 and 102.5 versus 10.8%, respectively). The use of antihypertensives used to treat severe range hypertension increased with use of intravenous labetalol increasing 31.5%, 43.2%, and 36.1% at low-, medium-, and high-volume hospitals. Comorbid risk also increased across hospital volume settings as did risk for severe maternal morbidity. Preeclampsia is increasing across obstetric care settings with preeclamptic patients demonstrating increasing comorbid risk, increased risk for severe morbidity, and more frequent need for treatment of acute hypertension.

Preeclampsia - will orphan drug status facilitate innovative biological therapies?

Science.gov (United States)

Hahn, Sinuhe

2015-01-01

It is generally accepted that the development of novel therapies to treat pregnancy-related disorders, such as preeclampsia, is hampered by the paucity of research funding. Hence, it is with great interest to become aware of at least three novel therapeutic approaches for the treatment of this disorder: exploiting either the anticoagulant activity of antithrombin, the free radical scavenging activity of alpha-1-microglobulin, or the regenerative capacity of placenta-derived mesenchymal stem cells. As these projects are being carried out by small biotech enterprises, the question arises of how they are able to fund such undertakings. A novel strategy adopted by two of these companies is that they successfully petitioned US and EU agencies in order that preeclampsia is accepted in the register of rare or orphan diseases. This provides a number of benefits including market exclusivity, assistance with clinical trials, and dedicated funding schemes. Other strategies to supplement meager research funds, especially to test novel approaches, could be crowdfunding, a venture that relies on intimate interaction with advocacy groups. In other words, preeclampsia meets Facebook. Perhaps similar strategies can be adopted to examine novel therapies targeting either the imbalance in pro- or anti-angiogenic growth factors, complement activation, reduced levels of placenta protein 13, or excessive neutrophil activation evident in preeclampsia.

Full Text Available Background: Preeclampsia and eclampsia during pregnancy contribute to maternal and fetal morbidity as well as mortality. The identification of the role of maternal nutrition during pregnancy will help in reducing morbidity and mortality. Aims & Objective: The objective of this study is to find out the role of nutrition, in the form of total calorie, protein, fruits, iron, folic acid and calcium intake in the development of preeclampsia and eclampsia among pregnant women in a tertiary level hospital. Material Methods: After ethical approval and informed consent, 122 women who delivered beyond 22 weeks of gestation and diagnosed as preeclampsia or eclampsia were selected. Simultaneously, 122 controls with no diagnosis of preeclampsia or eclampsia were selected from the post natal ward. Cases and controls were administered the same pre-tested questionnaire containing questions related to food and micronutrient intake by cases and control. Results: Logistic regression was applied in the statistical analysis. The factors that were found to be significant predictors of risk for development of preeclampsia and eclampsia were higher calorie intake (adjusted Odds Ratio (OR 14.12 [6.41-43.23] P < 0.001, less protein intake (adjusted OR 3.87 [1.97-8.01] P < 0.001 during pregnancy. Fruits intake in both cases and controls were similar. 77.9% of cases and 84.4% of controls had taken iron tablets during their antenatal period. 75.4% of cases and 82.8% of controls had taken calcium tablets during their antenatal period. Iron and calcium intake is not significantly associated with development of preeclampsia and eclampsia. Conclusion: Higher calorie intake and less protein intake during pregnancy were associated with development of preeclampsia and eclampsia. Fruits intake, iron and calcium intake were not associated with development of preeclampsia and eclampsia

Preeclampsia, a multisystem hypertensive disorder of pregnancy, is associated with increased systemic vascular resistance. Placentae from patients with preeclampsia have reduced levels of endothelial nitric oxide synthase (eNOS) and, thus, less nitric oxide (NO). Syncytiotrophoblast extracellular vesicles (STBEV), comprising microvesicles (STBMV) and exosomes, carry signals from the syncytiotrophoblast to the mother. We hypothesized that STBEV-bound eNOS (STBEV-eNOS), capable of producing NO, are released into the maternal circulation. Dual-lobe ex vivo placental perfusion and differential centrifugation was used to isolate STBEV from preeclampsia (n=8) and normal pregnancies (NP; n=11). Plasma samples of gestational age-matched preeclampsia and NP (n=6) were used to isolate circulating STBMV. STBEV expressed placental alkaline phosphatase, confirming placental origin. STBEV coexpressed eNOS, but not inducible nitric oxide synthase, confirmed using Western blot, flow cytometry, and immunodepletion. STBEV-eNOS produced NO, which was significantly inhibited by N   G -nitro-l-arginine methyl ester (eNOS inhibitor; P preeclampsia-perfused placentae had lower levels of STBEV-eNOS (STBMV; P preeclampsia women had lower STBEV-eNOS expression compared with that from NP women ( P preeclampsia placentae, as well as in plasma. The lower STBEV-eNOS NO production seen in preeclampsia may contribute to the decreased NO bioavailability in this disease. © 2017 The Authors.

Full Text Available Objectives. The pathophysiology of preeclampsia is characterized by abnormal placentation, an exaggerated inflammatory response, and generalized dysfunction of the maternal endothelium. We investigated the effects of preeclampsia serum on the expression of inflammation-related genes by adipose tissue. Materials and Methods. Visceral adipose tissue was obtained from the omentum of patients with early ovarian cancer without metastasis. Adipose tissue was incubated with sera obtained from either five women affected with severe preeclampsia or five women from control pregnant women at 37°C in a humidified incubator at 5% CO2 for 24 hours. 370 genes in total mRNA were analyzed with quantitative RT-PCR (Inflammatory Response & Autoimmunity gene set. Results. Gene expression analysis revealed changes in the expression levels of 30 genes in adipose tissue treated with preeclampsia sera. Some genes are related to immune response, oxidative stress, insulin resistance, and adipogenesis, which plays a central role in excessive systemic inflammatory response of preeclampsia. In contrast, other genes have shown beneficial effects in the regulation of Th2 predominance, antioxidative stress, and insulin sensitivity. Conclusion. In conclusion, visceral adipose tissue offers protection against inflammation, oxidative insults, and other forms of cellular stress that are central to the pathogenesis of preeclampsia.

Métodos: Estudo descritivo de prontuários de gestantes maiores de 15 anos, residentes em municípios de alto risco na Amazônia Legal. Antimaláricos caracterizados segundo frequência de prescrição, tipo de plasmódio e de unidade de saúde de atendimento, e de possíveis eventos adversos. Para comparação das variáveis estudas utilizou-se o teste do qui-quadrado de Pearson. Resultados: Foram avaliados 262 prontuários de gestantes. A maioria das gestantes pesquisadas recebeu diagnóstico de infecção por P. vivax (71,2%. Cloroquina foi o fármaco mais prescrito (65,6%. Fármacos não recomendados foram encontrados em 9,0% e 16,2% das prescrições para P. vivax e P. falciparum , respectivamente. Prescrições para P. falciparum , em proporção significativamente maior, contiveram esquemas e posologia e/ou duração do tratamento não adequados ao protocolo oficial (p = 0,001, bem como sem especificação da posologia (p = 0,004. Não houve diferenças significativas entre hospitais de referência e unidades básicas de saúde quanto aos esquemas de tratamento, proporções de prescrições contendo esquemas de tratamento não adequados e sem especificação da posologia. Cloroquina foi o fármaco mais envolvido em ocorrências de eventos adversos. Conclusões: Os resultados mostraram deficiências na prescrição de antimaláricos para gestantes, especialmente quanto à adequação ao protocolo oficial.

Full Text Available A pesquisa de natureza quantitativa de tipo exploratório teve como objetivo geral discutir os motivos/fatores que levam as gestantes a consumirem bebidas alcoólicas. O cenário foi o ambulatório de pré-natal de um hospital universitário do Estado do Rio de Janeiro. Fizeram parte do estudo 40 gestantes, tendo como instrumento de coleta de dados dois formulários com perguntas fechadas. A análise dos dados evidenciou que 10% das gestantes possuíam o hábito de consumir bebidas alcoólicas moderadamente, sendo o principal fator motivacional a presença em festas e comemorações, além de se sentirem felizes e descontraídas no momento do consumo. Quanto ao conhecimento sobre a teratogenia do álcool, constatou-se que apenas metade das gestantes que consumiram bebidas alcoólicas acreditava que esta prática poderia afetar seu filho. O estudo revelou que dados como o estilo de vida devem ser valorizados em assistência pré-natal pela enfermeira, direcionando ações educativas que visem à qualidade de vida do núcleo familiar.The research of quantitative and explorer nature had the general objective to argue the reasons/factors that take the pregnant women to consume alcoholic beverage. The scene was the Prenatal clinic of the Hospital Antonio Pedro, Niterói. Forty future mothers had been part of the study, having as instrument of collection of data two forms with closed questions. The analysis of the data evidenced that 10% of the pregnant women had the habit to consume moderately alcoholic beverage, being the main reason the presence in parties and commemorations beyond felt happy and relaxed at the moment of consumption. About the knowledge on the teratogen of the alcohol, it was evidenced that only half of the pregnant women that had consumed alcoholic beverage believed that this practical could affect its son. The study disclosed that data as the life style must be valued in Prenatal assistance being able to direct educative actions

Pre-eclampsia is one of the most commonly encountered hypertensive disorders of pregnancy that accounts for 20-80% of maternal mortality in developing countries, including Ethiopia. For many years, diet has been suggested to play a role in pre-eclampsia. However, the hypotheses have been diverse with inconsistent results across studies, and this has not been studied in Ethiopia. The objective of this study was to determine the effect of dietary habits on the incidence of pre-eclampsia in Bahir Dar, Ethiopia A prospective multicentre unmatched case-control study was conducted among 453 (151 cases and 302 controls) pregnant women attending antepartum or intrapartum care in public health facilities of Bahir Dar City from June to September 2014. The interviewer conducted a face-to-face interview, measured the mid-upper arm circumference (MUAC) and collected the mid-pregnancy haemoglobin level from clinical notes using a standardized and pretested questionnaire. Epi Info 3.5.3 was used for data entry and cleaning, while IBM SPSS Statistics 20 was used for data analysis. Backward stepwise unconditional logistic regression analysis was employed to determine the strength of association of predictive variables with the outcome variable and to control for the effect of confounding variables. A P-value ≤0.05 was considered statistically significant. For every 1-cm increase of MUAC, there was an increase in the incidence rate of pre-eclampsia by a factor of 1.35 (adjusted odds ratio (AOR)=1.35, 95% confidence interval (CI): 1.21, 1.51). A higher incidence of pre-eclampsia was found in women who reported to have consumed coffee daily during pregnancy (AOR=1.78, 95% CI: 1.20, 3.05). Similarly, for women who had anaemia during the first trimester, the incidence of pre-eclampsia was 2.5 times higher than their counterparts (AOR=2.47, 95% CI: 1.12, 7.61). This study also revealed consumption of fruit or vegetables at least three times a week during pregnancy to be protective

Maternal asthma and air pollutants have been independently associated with preeclampsia but rarely studied together. Our objective was to comprehensively evaluate preeclampsia risk based on the interaction of maternal asthma and air pollutants. Preeclampsia and asthma diagnoses, demographic and clinical data came from electronic medical records for 210,508 singleton deliveries. Modified Community Multiscale Air Quality models estimated preconception, first and second trimester and whole pregnancy exposure to: particulate matter (PM)<2.5 and <10 µm, ozone, nitrogen oxides (NO{sub x}), sulfur dioxide (SO{sub 2}) and carbon monoxide (CO); PM{sub 2.5} constituents; volatile organic compounds (VOCs) and polycyclic aromatic hydrocarbons (PAHs). Asthma-pollutant interaction adjusted relative risks (RR) and 95% confidence intervals (CI) for preeclampsia were calculated by interquartile range for criteria pollutants and high exposure (≥75th percentile) for PAHs and VOCs. Asthmatics had higher risk associated with first trimester NO{sub x} and SO{sub 2} and whole pregnancy elemental carbon (EC) exposure than non-asthmatics, but only EC significantly increased risk (RR=1.11, CI:1.03–1.21). Asthmatics also had a 10% increased risk associated with second trimester CO. Significant interactions were observed for nearly all VOCs and asthmatics had higher risk during all time windows for benzene, ethylbenzene, m-xylene, o-xylene, p-xylene and toluene while most PAHs did not increase risk. - Highlights: • Asthma is common in pregnancy and asthmatic women have increased preeclampsia risk. • Air pollution could differentially increase preeclampsia risk for asthmatic women. • Preeclampsia risk was higher for asthmatics than non-asthmatics after VOC exposure. • Asthmatics also had higher risk after whole pregnancy exposure to elemental carbon. • Pregnant women with asthma appear to be particularly vulnerable to air pollutants.

Cerebrovascular reactivity (CVR) is reduced in patients with cognitive decline. Women with a history of preeclampsia are at increased risk for cognitive decline. This study examined an association between pregnancy history and CVR using a subgroup of 40 age- and parity-matched pairs of women having histories of preeclampsia (n=27) or normotensive pregnancy (n=29) and the association of activated blood elements with CVR. Middle cerebral artery velocity was measured by Doppler ultrasound before and during hypercapnia to assess CVR. Thirty-eight parameters of blood cellular elements, microvesicles, and cell-cell interactions measured in venous blood were assessed for association with CVR using principal component analysis. Middle cerebral artery velocity was lower in the preeclampsia compared with the normotensive group at baseline (63±4 versus 73±3 cm/s; P =0.047) and during hypercapnia ( P =0.013-0.056). CVR was significantly lower in the preeclampsia compared with the normotensive group (2.1±1.3 versus 2.9±1.1 cm·s·mm Hg; P =0.009). Globally, the association of the 7 identified principal components with preeclampsia ( P =0.107) and with baseline middle cerebral artery velocity ( P =0.067) did not reach statistical significance. The interaction between pregnancy history and principal components with respect to CVR ( P =0.084) was driven by a nominally significant interaction between preeclampsia and the individual principal component defined by blood elements, platelet aggregation, and interactions of platelets with monocytes and granulocytes ( P =0.008). These results suggest that having a history of preeclampsia negatively affects the cerebral circulation years beyond the pregnancy and that this effect was associated with activated blood elements. © 2017 American Heart Association, Inc.
