Abstract Objective To analyze the effects of calcium supplementation on markers of preeclampsia over time by comparing the use of high- and low-dose calcium in hypertensive pregnant women. Methods This is a randomized clinical trial, placebo controlled, with three parallel groups carried out at the reference outpatient clinic for high-risk prenatal care in the South Region of Brazil, with intention-to-treat analysis and follow-up after four and eight weeks. The intervention consisted of ingesting calcium 500mg/day, calcium 1500mg/day and placebo. Data were analyzed according to a generalized mixed equation estimation model adopting α 0.05. Results The effect of low- and high-dose calcium on evolution over time was maintained between groups, even after adjustment for confounding factors. There was a significant difference in the parameters analyzed in the time and group interaction (p <0.000) and a decrease in the means of 12.3 mmHg in SBP, 9.2 mmHg in DBP, 3.2 mg/dl creatinine and 7.2 mg/dl proteinuria for the 500mg calcium/day group. The results were similar for the maximal supplementation group. Conclusion Calcium improved vascular prognosis in hypertensive pregnant women by reducing blood pressure levels and markers of preeclampsia. Brazilian Registry of Clinical Trials: RBR-9ngb95

Uso de labetalol frente a nifedipino en la preeclampsia / Use of labetalol vs nifedipine in preeclampsia

Fundamento: La preeclampsia es un estado de vasoconstricción generalizado asociado a la disfunción del epitelio vascular en vez de vasodilatación propia del embarazo, caracterizada por la hipertensión proteinuria a partir de la semana 20, acompañada a veces de edemas; asimismo constituye un peligro de salud para la madre y el feto. El tratamiento clínico tradicional utiliza fármacos antihipertensivos por vía oral, entre los que se mencionan el labetalol y nifedipino de liberación prolongada. Objetivo: Analizar la efectividad del labetalol y del nifedipino como tratamiento antihipertensivo relacionado con preeclampsia. Metodología: Se recurrió a fuentes de consulta encontradas en Google Scholar, Science Direct, SciELO, Pubmed, Medes y Elsevier. De 211 fuentes se seleccionaron 31 de acuerdo con criterios de inclusión y exclusión. Conclusiones: Por consenso se ha determinado que en la mayor parte de fuentes de consulta el nifedipino por vía oral es más efectivo que el labetalol en el tratamiento de la preeclampsia.

Background: Pre-eclampsia is a generalized vasoconstriction state associated with vascular epithelial dysfunction rather than the vasodilation characteristic of pregnancy, characterized by proteinuric hypertension from the 20th week of pregnancy, sometimes associated with edema; it also causes health risks to the mother and fetus. Traditional clinical treatment uses oral antihypertensive drugs, among these labetalol and extended-release nifedipine are included. Objective: To analyze the efficacy of labetalol and nifedipine as an antihypertensive treatment in pre-eclampsia. Methodology: Reference sources found in Google Scholar, Science Direct, SciELO, Pubmed, Medes and Elsevier were used. Out of 211 sources, 31 were selected according to inclusion and exclusion criteria. Conclusions: It has been determined by majority consensus that oral nifedipine is more effective than labetalol in pre-eclampsia treatment.

Exposição ao cádmio e Síndromes Hipertensivas da Gestação: uma revisão sistemática / Cadmium exposure and Hypertensive Disorders of Pregnancy: a systematic review

RESUMO As Síndromes Hipertensivas da Gestação (SHG) são uma das principais causas de morbimortalidade materna. Evidências crescentes indicam a associação entre a exposição ao cádmio e a hipertensão arterial na população em geral, mas não as SHG. Afim de investigar esse tema, realizou-se uma revisão sistemática seguindo as diretrizes PRISMA, nas bases de dados BVS/Lilacs, PubMed/Medline e SciELO e no repositório da Universidade de São Paulo (USP) até agosto de 2021. A qualidade metodológica foi avaliada pelo checklist Downs and Black. Selecionaram-se dezenove artigos, sendo treze caso-controle, quatro coortes e dois seccionais. No total, 11.451 participantes foram avaliadas, sendo 1.445 (12,6%) com SHG e, destas, 1.071 (74,1%) com pré-eclâmpsia. Observou-se o ajuste inadequado para confundimento em onze estudos. Dos sete estudos considerados de boa qualidade metodológica, quatro relataram associação positiva e três não a observaram, enquanto somente um estudo observou diferença de média, que foi maior nas gestantes com SHG. Atribuiu-se a divergência dos resultados às diferenças metodológicas e ao ajuste inadequado para os fatores de confusão. Como o cádmio é um metal tóxico que pode levar ao aumento do estresse oxidativo, que desempenha papel importante na fisiopatologia das SHG, estudos adicionais são necessários para elucidar esta associação.

ABSTRACT Hypertensive Disorders of Pregnancy (HDP) are one of the main causes of maternal morbimortality. Strong evidence point to an association between cadmium and hypertension in the general population, but not HDP. A systematic review was carried out to investigate this potential relationship, following PRISMA guidelines, in the BVS/LILACS, PubMed/MEDLINE, and SciELO databases and a repository (University of São Paulo - USP) until August 2021. The methodological quality was assessed using the Downs and Black checklist. Nineteen articles were selected, thirteen of which were case-control, four were cohorts, and two were cross-sectional. A total of 11.451 participants were evaluated, 1.445 (12.6%) with HDP, and of these 1.071 (74.1%) with preeclampsia. The inadequate adjustment for confounding was observed in eleven studies. Out of the seven studies considered good methodological quality, four reported a positive association, and three did not observe it. In contrast, only one observed a mean difference, which was higher in HDP. The inconsistency of the results was attributed to the methodological differences and inadequate adjustment for confounding. As cadmium is a toxic metal that can induce an increase in oxidative stress, which plays an essential role in the pathophysiology of HDP, additional studies are needed to elucidate this association.

Maternal-fetal outcomes of women with hypertensive disorders of pregnancy

SUMMARY OBJECTIVE: The objective of this study was to determine adverse maternal and perinatal outcomes in pregnant women with hypertensive disorders of pregnancy. METHODS: An analytical cross-sectional study was conducted on women admitted with hypertensive disorders of pregnancies to a university maternity hospital from August 2020 to August 2022. Data were collected using a pretested structured questionnaire. Variables associated with adverse maternal and perinatal outcomes were compared using multivariable binomial regression. RESULTS: Of 501 women with pregnancies, 2, 35, 14, and 49% had eclampsia, preeclampsia, chronic hypertension, and gestational hypertension, respectively. Women with preeclampsia/eclampsia had significantly higher risks of cesarean section (79.4 vs. 65%; adjusted RR, 2,139; 95%CI, 1,386-3,302; p=0.001) and preterm delivery at <34 weeks' gestation (20.5 vs. 6%; adjusted RR, 2.5; 95%CI, 1.19-5.25; p=0.01) than those of women with chronic/gestational hypertension. Risks of prolonged maternal hospitalization (43.9 vs. 27.1%), neonatal intensive care unit admission (30.7 vs. 19.8%), and perinatal mortality (23.5 vs. 11.2%) were higher among women with preeclampsia/eclampsia. CONCLUSIONS: Women with preeclampsia/eclampsia had a higher risk of adverse maternal and neonatal outcomes than those with chronic or gestational hypertension. This major maternity care center requires strategies for preventing and managing preeclampsia/eclampsia to improve pregnancy outcomes.

Risk factors for hypertensive disorders in pregnancy in women residing in high altitude areas and their impacts on maternal and infant outcomes / 中华围产医学杂志

Objective:To investigate the incidence and risk factors of hypertensive disorders in pregnancy (HDP) in high altitude areas and their influence on maternal and infant outcomes.Methods:This was a retrospective case-control study. A total of 220 newborns were selected as the high altitude group, who were born to 216 mothers with HDP and admitted to the Neonatal Intensive Care Unit of the Lhasa People's Hospital from June 1, 2018, to June 1, 2020. The low altitude group consisted of 235 newborns born to 231 mothers with HDP and admitted to the Department of Neonatology of the Children's Hospital Affiliated to Beijing Capital Institute of Pediatrics from January 1, 2018, to December 31, 2021. Differences in the types of HDP between the two groups and the risk factors for the high incidence of preeclampsia-eclampsia and early-onset preeclampsia in high altitude area were analyzed. The influences of HDP in high and low altitude areas on maternal and infant outcomes were compared. Statistical analysis was performed using t-test, Mann-Whitney U test, Pearson Chi-square test, or continuous correction Chi-square test, and univariate and multivariate logistic regression analysis. Results:Maternal age and the proportions of primiparae and women of advanced age or having irregular prenatal examination were greater in the high altitude group than those in the low altitude group (all P<0.05). Besides, the incidence of early-onset preeclampsia, eclampsia, preeclampsia-eclampsia, and chronic hypertension complicated by preeclampsia were also higher in the high altitude group (all P<0.05). Multivariate logistic regression analysis showed that high altitude was a risk factor for the development of preeclampsia-eclampsia ( OR=4.437, 95% CI:2.582-7.626). Adverse pregnancy history ( OR=2.576, 95% CI:1.217-5.452) and irregular prenatal examination ( OR=2.862, 95% CI:1.412-5.800) were independent risk factors for early-onset preeclampsia in pregnant women in high altitude areas. Twin-pregnancy was a protective factor for early-onset preeclampsia in pregnant women in high altitude areas ( OR=0.183, 95% CI: 0.054-0.623). The incidence of maternal heart failure [7.9% (17/216) vs 0.4% (1/231), χ2=15.98], placental abruption [7.9% (17/216) vs 3.5% (8/231), χ2=4.11], hemolysis, elevated liver function and low platelet count syndrome [14.4% (31/216) vs 1.7% (4/231), χ2=24.64], premature delivery [86.1% (118/216) vs 73.6% (170/231), χ2=10.79], fetal growth restriction [52.3% (115/220) vs 18.7% (44/235), χ2=56.26], fetal distress [18.2% (40/220) vs 8.1% (19/235), χ2=10.26], neonatal asphyxia [29.5% (65/220) vs 11.1% (26/235), χ2=24.26], severe asphyxia [8.6% (19/220) vs 2.6% (6/235), χ2=8.10] and the proportion of neonates requiring mechanical ventilation within 24 h after birth [69.5% (153/220) vs 42.6% (100/235), χ2=33.54] as well as neonatal death within 7 d after birth [5.5% (12/220) vs 1.3% (3/235), χ2=6.22] in the high altitude group were significantly higher than those in the low altitude group (all P<0.05). Conclusion:High altitude is a risk factor for preeclampsia-eclampsia, and the adverse effects of HDP on mothers and infants are more severe in high altitude areas.

Immature Platelet Fraction and Thrombin Generation: Preeclampsia Biomarkers / Fração de plaquetas imaturas e geração de trombina: Biomarcadores da pré-eclâmpsia

Abstract Preeclampsia, a human pregnancy syndrome, is characterized by elevated blood pressure and proteinuria after the 20th week of gestation. Its etiology remains unknown, and its pathophysiological mechanisms are related to placental hypoperfusion, endothelial dysfunction, inflammation, and coagulation cascade activation. Recently, the role of the complement system has been considered. This syndrome is one of the main causes of maternal and fetal mortality and morbidity. This article discusses the hypothesis of preeclampsia being triggered by the occurrence of inadequate implantation of the syncytiotrophoblast, associated with bleeding during the first stage of pregnancy and with augmented thrombin generation. Thrombin activates platelets, increasing the release of antiangiogenic factors and activating the complement system, inducing the membrane attack complex (C5b9). Immature platelet fraction and thrombin generation may be possible blood biomarkers to help the early diagnosis of preeclampsia.

Resumo A pré-eclâmpsia, uma síndrome da gestação humana, é caracterizada por elevação da pressão arterial e proteinúria patológica após a 20ª semana de gestação. Sua etiologia permanece desconhecida, e seus mecanismos fisiopatológicos estão relacionados à hipoperfusão placentária, disfunção endotelial, inflamação, e ativação da cascata de coagulação. Recentemente, o papel do sistema do complemento foi considerado. Essa síndrome é uma das principais causas de morbidade e mortalidade materna e fetal. Este artigo discute a hipótese de a pré-eclâmpsia ser desencadeada pela ocorrência da implantação inadequada do sinciciotrofoblasto, associada ao sangramento durante o primeiro trimestre da gravidez com aumento da geração de trombina. A trombina ativa plaquetas, aumentando a liberação de fatores antiangiogênicos na circulação e ativando o sistema do complemento, especialmente o complexo de ataque de membrana (C5b9). Portanto, a fração de plaquetas imaturas e a geração de trombina podem ser possíveis biomarcadores sanguíneos para auxílio no diagnóstico precoce da pré-eclâmpsia.

Resultados de un registro prospectivo de pacientes con desórdenes hipertensivos del embarazo en un centro de la Ciudad de Buenos Aires / Results of a Prospective Registry of Patients with Hypertensive Disorders of Pregnancy in a Center of the City of Buenos Aires

RESUMEN Introducción: Los desórdenes hipertensivos del embarazo (DHE) complican el 10% de los embarazos. Son la principal causa de mortalidad materna, y requieren un equipo multidisciplinario para su abordaje. Objetivos: Cuantificar prevalencia y definir características y evolución de los DHE en un centro con un programa dedicado para su abordaje. Material y métodos: Registro continuo y prospectivo desde noviembre 2019 hasta julio 2021 que incluyó todas las pacientes con DHE (Hipertensión arterial crónica - HTAC, hipertensión gestacional - HTg, preeclampsia precoz - PEp, preeclampsia tardía - PEt, preeclampsia sobreimpuesta - PESI, y eclampsia) y que cumplieran los criterios de inclusión. Se excluyeron las pacientes sin cobertura médica que impidiera su seguimiento ambulatorio a largo plazo en la institución. Se evaluaron características basales y evolución, tratamiento y persistencia de HTA luego del puerperio. Se analizó la incidencia de retardo en el crecimiento intrauterino (RCIU), parto pretérmino, mortalidad materna y muerte neonatal dentro de los primeros 28 días de vida. Resultados: Se realizaron 5825 partos/cesáreas y se incluyeron 152 pacientes que cumplieron criterios de inclusión, con HTg (37,5%), PEp (19,7%), PEt (38,8%), PESI (3,3%)), eclampsia (0,6%). Edad media 36,4 ± 5,6 años. El 38,1% recibió aspirina. Los antihipertensivos más utilizados fueron labetalol (65,8%) y enalapril (44,1 %) en el embarazo y el puerperio respectivamente. No hubo mortalidad materna, y la neonatal fue 3,6%. La persistencia de HTA fue del 20,0% Conclusión: La preeclampsia tardía fue el DHE más frecuente en la población analizada. Más de la mitad de las pacientes que desarrollaron DHE no recibían tratamiento preventivo con aspirina, evidenciándose un déficit en la identificación de la población de riesgo. Una de cada 5 pacientes con DHE quedó con hipertensión arterial crónica luego del puerperio.

ABSTRACT Background: Hypertensive disorders of pregnancy (HDP) complicate 10% of pregnancies. They are the main cause of maternal mortality and require a multidisciplinary team to address them. Objectives: The aim of this study was to quantify the prevalence and define the characteristics and outcome of HDP in a center with a program focused on its management. Methods: This was a continuous and prospective registry from November 2019 to July 2021 that included all patients with HDP [chronic hypertension (CHT), gestational hypertension (GHT), early-onset preeclampsia (EPE), late preeclampsia (LPE), superimposed preeclampsia (SIPE) and eclampsia] who met the inclusion criteria. Patients without medical coverage that prevented long-term outpatient follow-up at the institution were excluded. Baseline characteristics and evolution, treatment and persistent HT after puerperium were evaluated. The incidence of intrauterine growth retardation (IUGR), preterm delivery, maternal mortality and neonatal death within the first 28 days of life was analyzed. Results: Among a total f 5825 deliveries/caesarean sections, 152 patients with GHT (37.5%), EPE (19.7%), LPE (38.8%), SIPE (3.3%), and eclampsia (0.6%) who met the inclusion criteria were included in the study. Mean age was 36.4±5.6 years. Aspirin was administered to 38.1% of patients. The most commonly used antihypertensive drugs were labetalol (65.8%) and enalapril (44.1%) during pregnancy and puerperium, respectively. There was no maternal mortality, and neonatal mortality was 3.6%. Persistent HT was 20.0%. Conclusion: Late preeclampsia was the most frequent HDP in the population analyzed. More than half of the patients who developed HDP did not receive preventive treatment with aspirin, showing a deficit in the identification of the population at risk. One in 5 HDP patients remained with CHTN after puerperium.

RESUMEN Objetivos: Proveer recomendaciones clínicas basadas en evidencia para la prevención y el manejo de la enfermedad hipertensiva del embarazo (EHE) en el Seguro Social de Salud (EsSalud) del Perú. Materiales y métodos: se conformó un grupo elaborador de la guía (GEG) que incluyó médicos especialistas y metodólogos. El GEG formuló ocho preguntas clínicas para ser respondidas por la presente Guía de Práctica Clínica (GPC). Se realizaron búsquedas sistemáticas de revisiones sistemáticas y, cuando se consideró pertinente, estudios primarios en PubMed y Central durante 2021. Se seleccionó la evidencia para responder cada una de las preguntas clínicas planteadas . En reuniones de trabajo periódicas, el GEG usó la metodología Grading of Recommendations Assessment, Development, and Evaluation (GRADE) para calificar la evidencia y formular las recomendaciones. Además se resentan los puntos de buenas prácticas clínicas (BPC) y los flujogramas de prevención, manejo y seguimiento. Finalmente, la GPC fue aprobada por Resolución 112-IETSI-ESSALUD-2021. Resultados: En la presente GPC se formularon 11 recomendaciones (6 fuertes y 5 condicionales) que respondieron las preguntas clínicas definidas en el alcance de la GPC, acompañadas de 32 puntos de BPC y 3 flujogramas que abordan temas de prevención, tratamiento y seguimiento de la EHE. Conclusiones: Como recomendaciones centrales de la guía se dan el uso de sulfato de magnesio para el tratamiento de la preeclampsia severa y la eclampsia. La guía deberá ser actualizada en tres años.

ABSTRACT Objectives: To provide clinical recommendations based on evidence for the prevention and management of Hypertensive disorders of pregnancy (HDP) in the Social Health Insurance (EsSalud) of Peru. Materials and methods: A CPG for the the prevention and management of HDP in EsSalud was developed. To this end, a guideline development group (local GDG) was established, including medical specialists and methodologists. The local GDG formulated 8 clinical questions to be answered by this CPG. Systematic searches of systematic reviews and -when it was considered pertinent- primary studies were searched in PubMed y Central during 2021. The evidence to answer each of the posed clinical questions was selected. The quality of the evidence was evaluated using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. In periodic work meetings, the local GDG used the GRADE methodology to review the evidence and formulate the recommendations, the points of good clinical practice and flowcharts for the prevention, management and follow-up. Finally, the CPG was approved with Resolution 112-IETSI-ESSALUD-2021. Results: This CPG addressed 8 clinical questions, divided into three topics: prevention, management and follow-up of the HDP. Based on these questions, 11 recommendations (6 strong recommendations and 5 weak recommendations), 32 points of good clinical practice, and 3 flowcharts were formulated. Conclusions: The main recommendations in the guideline are the use of magnesium sulfate for the treatment of severe pre-eclampsia and eclampsia. The guideline must be updated in three years' time.

ABSTRACT Objective. To estimate the point prevalence and likely ranges of pregnancy-induced hypertension, pre-eclampsia, gestational diabetes, low birth weight and preterm delivery in Latin America and the Caribbean, and evaluate the heterogeneity of the estimates. Methods. We conducted a systematic review and meta-analysis of observational studies reporting the prevalence of maternal and perinatal adverse outcomes in populations in Latin American and the Caribbean published between 2000 and 2019 in English, Spanish, or Portuguese. We searched PubMed, Embase, and LILACS. We estimated the point prevalence and evaluated overall heterogeneity and, in sub-group analyses, heterogeneity by study design and level of bias. Results. Of 1087 records retrieved, 50 articles were included in the review: two on hypertensive disorders of pregnancy, 14 on pre-eclampsia, six on gestational diabetes, nine on low birth weight and 19 on preterm birth. No meta-analysis for hypertensive disorders of pregnancy could be done because of the small number of studies. Point prevalence estimates and 95% confidence intervals (CIs) for pre-eclampsia, gestational diabetes, low birth weight, and preterm birth were: 6.6% (95% CI: 4.9%, 8.6%), 8.5% (95% CI: 3.9%, 14.7%), 8.5% (95% CI: 7.2%, 9.8%), and 10.0% (95% CI: 8.0%, 12.0%), respectively. We observed substantial heterogeneity overall and by study design. No major differences in estimates were observed by level of bias. Conclusions. The results of this study provide updated estimates of some of the most prevalent adverse pregnancy and perinatal outcomes in Latin America and the Caribbean. They highlight that important heterogeneity exists in prevalence estimates, which may reflect the diversity of populations in the region.

On management of mild hypertension during pregnancy / 中华围产医学杂志

It has been accepted that pregnant women should receive antihypertensive therapy when the blood pressure is ≥160/110 mmHg (1 mmHg=0.133 kPa). However, a consensus is yet to be reached worldwide regarding whether lowering blood pressure is required for pregnant women with mild hypertension (blood pressure <160/110 mmHg). Diagnosis and treatment of hypertension and pre-eclampsia in pregnancy: a clinical practice guideline in China (2020) recommends that pregnant women whose blood pressure are ≥140/90 mmHg should be treated with antihypertensive therapy. A recent study has shown that antihypertensive therapy for pregnant women with blood pressure over 140/90 mmHg could improve the pregnancy outcomes, providing further evidence for the recommendation in the 2020 guideline in China. Current studies have shown that the risk of adverse pregnancy outcomes increases in pregnant women with normal high blood pressure (130-139/80-89 mmHg), which indicates that effective management measures such as close monitoring should be conducted for this population, in order to reduce the adverse pregnancy outcomes.

Adverse outcomes of hypertensive disorders of pregnancy: development and validation of a predictive model / 中华围产医学杂志

Objective:To develop and validate a predictive model for adverse outcomes in women with hypertensive disorders of pregnancy (HDP).Methods:We retrospectively analyzed the clinical data of patients diagnosed with HDP and delivered at the First Affiliated Hospital of Soochow University or Sichuan Provincial Maternity and Child Health Care Hospital between May 1, 2011, and April 30, 2019. These patients were categorized as the adverse outcome group or the control group with adverse outcomes within 48 h after admission. Univariate analysis, least absolute shrinkage, selection operator (LASSO), and multivariable logistic regression were employed to analyze factors influencing the adverse outcomes and develop a predictive model. The receiver operating characteristic (ROC) curve and calibration plot was used to assess the predictive performance. Bootstrapping was used for the internal validation and the retrospective dataset of patients with HDP from the First Affiliated Hospital of Soochow University from May 1, 2019, to April 30, 2020, for the external validation. A graphic nomogram was created through R software based on the model.Results:(1) Of the 2 978 HDP patients who were included in the development set, 356 were in the adverse outcome group, accounting for 12.0%; of the 233 patients who were included in the external validation set, 40 presented with adverse outcomes within 48 h after admission, accounting for 17.2%. (2) Nine optimal predictors were identified based on the LASSO regression analysis and multivariable logistic regression, consisting of gestational age on admission, routine prenatal care, number of symptoms, mean arterial pressure, platelet count, fibrinogen, albumin, serum urea, and serum creatinine, based on which the logistic predictive model was established. (3) The ROC curve for this predictive model achieved an area under the curve (AUC) of 0.878 (95% CI: 0.858-0.897), and the ideal cut-off value for predicted probability was 0.136, with a sensitivity of 0.778 (95% CI: 0.731-0.820) and specificity of 0.848(95% CI: 0.834-0.862). The model was well-calibrated as the Hosmer-Lemeshow test showed that P>0.05. The calibration plot of the model had a slope of 1 and an intercept of 0. (4) The model showed good consistency in the internal validation and had an AUC of 0.872 (95% CI: 0.807-0.937) in the external validation. The Hosmer-Lemeshow test showed that the P value was >0.05, and the calibration slope was 1.001. (5) A nomogram was constructed for convenient clinical use. Conclusion:A relatively accurate prediction model for adverse outcomes in HDP patients was established, which could be used as a valuable quantitative tool for assessing HDP-related complications.

Dynamic evaluation of left ventricular systolic function in patients with pregnancy-induced hypertension by three-dimensional speckle tracking imaging / 中国基层医药

Objective:To investigate the clinical efficacy of three-dimensional speckle tracking imaging in the dynamic evaluation of left ventricular systolic function in patients with pregnancy-induced hypertension.Methods:50 patients with pregnancy-induced hypertension, who received prenatal examination in Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from July 2019 to June 2020 and finally gave birth, were included in the observation group. An additional 50 healthy pregnant women who concurrently received prenatal examination were included as controls. All participants underwent routine echocardiography and three-dimensional speckle tracking imaging examinations. Parameters related to left ventricular systolic function were recorded. Routine echocardiography parameters and three-dimensional speckle tracking imaging parameters were compared between the observation and control groups.Results:There were no significant differences in routine echocardiography parameters (including heart rate, left ventricular end-diastolic diameter, interventricular septum thickness in end-diastole, left ventricular posterior wall thickness in diastole, and left ventricular ejection fraction) between before treatment, after treatment, and 3 months after delivery in the observation group, and between observation and control groups before treatment (all P > 0.05). The absolute values of left ventricular global longitudinal strain (LVGLS) [(-18.41 ± 2.23)% vs. (-26.03 ± 2.79)%], left ventricular global circumferential strain (LVGCS) [(31.29 ± 3.09)% vs. (37.45 ± 3.68)%], left ventricular global radial strain (LVGRS) [(-19.37 ± 2.19)% vs. (-24.59 ± 2.74)%], and left ventricular global area peak systolic strain (LVGAS) [(-26.61 ± 3.18)% vs. (-39.23 ± 3.96)%] measured before treatment were significantly lower in the observation group than in the control group ( t = 6.31 -14.87, all P < 0.05). The absolute values of LVGLS, LVGCS, LVGRS, and LVGAS in the observation group were significantly higher after treatment [(-24.79 ± 2.68)%, (35.94 ± 3.25)%, (-22.48 ± 2.41)%, (-37.54 ± 3.38)%] and 3 months after delivery [(-25.64 ± 2.72)%, (36.63 ± 3.47)%, (-23.91 ± 2.69)%, (-38.49 ± 3.64)%] than before treatment ( t = 4.08 - 10.59, P < 0.05). There were no significant differences in LVGLS, LVGCS, LVGRS, and LVGAS between observation group and control groups at each time point studied ( t = 0.47 - 1.19, P = 0.182 - 0.652 > 0.05). The absolute svalues of LVGLS, LVGCS, LVGRS and LVGAS in patients with pregnancy-induced hypertension were positively correlated with left ventricular ejection fraction values ( r = 0.638 - 0.775, P = 0.009 - 0.041 < 0.05). Conclusion:Three-dimensional speckle tracking imaging can be used to dynamically evaluate the impairment of left ventricular systolic function in patients with pregnancy-induced hypertension. This technique helps guide early intervention and prognosis evaluation and has a high clinical application value.

Correlation analysis between phonographic cardiac function and uterine artery resistance index in pregnant women with hypertension of different conditions during pregnancy / 中国医师进修杂志

Objective:To analyze the correlation between phonographic cardiac function and uterine artery resistance index (RI) in pregnant women with hypertension of different conditions during pregnancy by color Doppler ultrasonically.Methods:A total of 100 pregnant women with gestational hypertension admitted to Lishui People′s Hospital from January 2020 to February 2021 were selected and divided into gestational hypertension group (40 cases), mild pre-eclampsia group (30 cases) and severe pre-eclampsia group (30 cases) according to the severity of their disease. Another 30 normal pregnant women who underwent physical examination during the same period were selected as the control group. The left ventricular function parameters isovolumetric relaxation time (IVRT), left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume (LVEDV), left ventricular end-systolic volume(LVESV), left atrial volume index (LAVI) and uterine arter RI in 4 groups were quantitatively analyzed by ultrasound during 28 to 38 weeks of gestation. The correlation between cardiac ultrasound parameters and of pregnant women RI were analyzed.Results:As the severity of the disease, the levels of IVRT, LVEDV, LVESV, LAVI were gradually rised, and the level of LVEF was gradually decreased, there were significant differences among the 4 groups ( P<0.05). The uterine arter RI in the control group, gestational hypertension group, mild pre-eclampsia group and severe pre-eclampsia group was 0.42 ± 0.04, 0.50 ± 0.05, 0.54 ± 0.11, 0.58 ± 0.06, there was significant difference ( F = 34.11, P<0.001), and as the severity of the disease , the level of uterine arter RI was gradually rised, there were significant differences among the 4 groups ( P<0.05). Pearson correlation analysis showed that IVRT had certain correlation with RI in the 4 groups ( r = 0.331, 0.450, 0.531, 0.582; P<0.05). In mild and severe pre-eclampsia group, there were a certain correlation between LVEDV, LVESV and RI (in mild pre-eclampsia group: r = 0.360 and 0.411, P<0.05; in severe pre-eclampsia group: r = 0.383 and 0.451, P<0.05). Conclusions:The left heart function of pregnant women with different conditions evaluated by ultrasound showed a downward trend, and the uterine artery RI increased gradually in pregnant women with severe pre-eclampsia, and RI was closely related to the cardiac ultrasound parameter IVRT.

Tratamiento de la eclampsia y miastenia gravis: reporte de un caso y revisión de la literatura / Eclampsia treatment and myasthenia gravis: case report and review of literature

OBJETIVO: Reportar el caso de una gestante con miastenia grave (MG) más preeclampsia-eclampsia y crisis miasténica en el puerperio mediato, y realizar una revisión de la literatura sobre el manejo farmacológico. MÉTODO: Se presenta el caso de una mujer de 26 años con MG, primigesta de 36 semanas de gestación, quien cursó con eclampsia y recibió fenitoína por 24 horas. Tuvo parto espontáneo sin complicaciones y crisis miasténica al día 11 del puerperio asociada a infección de vías urinarias y sepsis. Se realiza revisión de la literatura en PubMed, Cochrane, Embase, LILACS y Scopus, empleando los términos "Hypertension, Pregnancy-Induced", "Preeclampsia" y "Eclampsia", combinados con "Myasthenia Gravis", durante el periodo de publicación de 1960 a junio 2020, en inglés y español. RESULTADOS: Se encontraron 12 reportes de caso, dos con eclampsia y MG; el caso aquí reportado es el número 13. Ocho pacientes no recibieron medicamentos profilácticos de eclampsia y tres de ellas convulsionaron. En las que se usó sulfato de magnesio, todas cursaron con crisis miasténica. CONCLUSIONES: La evidencia actual en cuanto a la profilaxis y el tratamiento de la eclampsia y la MG corresponde a reportes de casos. El uso de sulfato de magnesio está contraindicado en pacientes con MG, por lo que se han utilizado fenitoína y levetiracetam.

OBJECTIVE: To report a case of pregnant women with myasthenia gravis (MG), plus preeclampsia-eclampsia and myasthenic crisis in the mediate puerperium; to conduct a literature review regarding its pharmacological management. METHOD: 26-year-old primigravida with 36 weeks of gestation and previous history of MG, who developed eclampsia and was treated with phenytoin for 24 hours, with later spontaneous delivery without any complications nor new seizures; and myasthenic crisis on day 11 of the puerperium associated with urinary tract infection and sepsis. A literature review was conducted in PubMed, Cochrane, Embase, LILACS and Scopus, using the controlled vocabulary "Hypertension, Pregnancy-Induced", "Preeclampsia" and "Eclampsia", combined with "Myasthenia Gravis", between 1960 and June 2020, in English and Spanish. RESULTS: 12 case reports were found, two of these with eclampsia and MG, the case reported here was number 13. In eight cases patients did not receive any prophylactic drugs for eclampsia and three of them had convulsions. In the cases where magnesium sulfate was used, all developed myasthenic crisis. CONCLUSIONS: The current evidence regarding prophylactic management and treatment corresponds to case reports. The use of magnesium sulfate is contraindicated in patients with MG, therefore phenytoin and levetiracetam have been used.
