COVID-19 and Preeclampsia: A Systematic Review of Pathophysiological Interactions / COVID-19 e pré-eclâmpsia: uma revisão sistemática de interações fisiopatológicas

Abstract Objective: To review the literature and synthesize evidence on pathophysiological interactions attributed to the simultaneous occurrence of COVID-19 and preeclampsia. Methods: A systematic review was conducted from November (2021) to January (2022) to retrieve observational studies published on the PubMed, LILACS, SciELO Brazil and Google Scholar databases. The search was based on the descriptors [(eclampsia OR preeclampsia) AND (COVID-19)]. Quantitative studies that pointed to pathophysiological interactions were included. Literature reviews, studies with HIV participants, or with clinical approach only were excluded. The selection of studies was standardized and the evaluation was performed by pairs of researchers. Results: In this review, 155 publications were retrieved; 16 met the inclusion criteria. In summary, the physiological expression of angiotensin-converting enzyme-2 (ACE-2) receptors is physiologically increased in pregnant women, especially at the placental site. Studies suggest that the coronavirus binds to ACE-2 to enter the human cell, causing deregulation of the renin-angiotensin-aldosterone system and in the ratio between angiotensin-II and angiotensin-1-7, inducing manifestations suggestive of preeclampsia. Furthermore, the cytokine storm leads to endothelial dysfunction, vasculopathy and thrombus formation, also present in preeclampsia. Conclusion: The studies retrieved in this review suggest that there is a possible overlap of pathophysiological interactions between COVID-19 and preeclampsia, which mainly involve ACE-2 and endothelial dysfunction. Given that preeclampsia courses with progressive clinical and laboratory alterations, a highly quality prenatal care may be able to detect specific clinical and laboratory parameters to differentiate a true preeclampsia superimposed by covid-19, as well as cases with hypertensive manifestations resulting from viral infection.

Resumo Objetivo: Revisar a literatura e sintetizar evidências sobre interações fisiopatológicas atribuídas à ocorrência simultânea de COVID-19 e pré-eclâmpsia. Métodos: Uma revisão sistemática foi conduzida entre novembro (2021) a janeiro (2022) para recuperar estudos observacionais publicados no PubMed, LILACS, SciELO Brasil e Google scholar. A busca foi baseada nos descritores [(eclâmpsia OR pré-eclâmpsia) AND (COVID-19)]. Estudos quantitativos que apontaram interações fisiopatológicas foram incluídos. Estudos de revisão, com participante HIV e apenas com enfoque clínico foram excluídos. A seleção dos estudos foi padronizada com avaliação por duplas de pesquisadores. Resultados: Nesta revisão, 155 publicações foram recuperadas; 16 preencheram os critérios de inclusão. Em síntese, a expressão fisiológica de receptores da enzima conversora da angiotensina-2 (ECA-2) é fisiologicamente potencializada em gestantes, especialmente no sítio placentário. Os estudos sugerem que o coronavírus se liga à ECA-2 para entrar na célula humana, ocasionando desregulação do sistema renina-angiotensina-aldosterona e da razão entre angiotensina-II e angiotensina-1-7, induzindo manifestações sugestivas de pré-eclâmpsia. Ademais, a tempestade de citocinas conduz à disfunção endotelial, vasculopatia e formação de trombos, também presentes na pré-eclâmpsia. Conclusão: Os estudos recuperados nesta revisão sugerem que a superposição de alterações fisiopatológicas entre a COVID-19 e a pré-eclâmpsia envolve, principalmente, a ECA-2 e disfunção endotelial. Tendo em vista que a pré-eclâmpsia cursa com alterações clínicas e laboratoriais progressivas, a atenção pré-natal de qualidade pode ser capaz de detectar parâmetros clínicos e laboratoriais importantes para diferenciar a pré-eclâmpsia verdadeira sobreposta por COVID-19, bem como os casos que mimetizam a doença hipertensiva consequente à infecção viral.

Esta tiene la capacidad de generar múltiples complicaciones en la gestante y el feto. Su diagnóstico oportuno y la toma de medidas preventivas ante sus factores de riesgo tienen la potencialidad para reducir la morbimortalidad por esta causa.

Preeclampsia/eclampsia is a manifestation of a hypertensive disease that can occur after the 20th week of pregnancy by generating multiple complications in the pregnant woman and the fetus. Its timely diagnosis and the taking of preventive measures against its risk factors can reduce morbidity and mortality.

Association between coagulation function indicators and placental abruption among preeclampsia-eclampsia pregnant women / 中华预防医学杂志

Objective: To explore the association between coagulation function indicators and placental abruption (PA) in different trimesters of pregnancy among preeclampsia-eclampsia pregnant women. Methods: From February 2018 to December 2020, pregnant women who participated in the China birth cohort study and were diagnosed with preeclampsia, eclampsia and chronic hypertension with superimposed preeclampsia in Beijing Obstetrics and Gynecology Hospital were enrolled in this study. The baseline and follow-up information were collected by questionnaire survey, and the coagulation function indicators in the first and third trimesters were obtained through medical records. The Cox proportional hazards model was used to analyze the association between the coagulation function indicators and PA. A restrictive cubic spline curve was used to draw the dose-response curve between the relevant coagulation function indicators and PA. Results: A total of 1 340 participants were included in this study. The age was (32.50±4.24) and the incidence of PA was 4.4% (59/1 340). After adjusting for relevant factors, Cox proportional hazards model showed that compared with the high-level classification of fibrinogen (FIB), participants within the middle-(HR=3.28, 95%CI: 1.27-8.48) and low-level (HR=3.84, 95%CI: 1.40-10.53) classification during the first trimester and within the low-level classification (HR=4.18, 95%CI: 1.68-10.39) during the third trimester were more likely to experience PA. Compared with the middle-level classification of pro-thrombin time (PT), the risk of PA in the participants within the low-level classification (HR=2.67, 95%CI: 1.48-4.82) was significantly higher in the third trimester. The restrictive cubic spline analysis showed a linear negative association between FIB and PA in the first and third trimesters, while PT and PA showed an approximately L-shaped association . Conclusion: Among pregnant women diagnosed with preeclampsia-eclampsia, the middle-and low-level classification of FIB in the first and third trimesters and the low-level classification of PT in the third trimester could increase the risk of PA.

Analysis of incidence and associated factors of preterm birth based on pre-pregnancy body mass index stratification / 中华预防医学杂志

Objective: To analyze the incidence of preterm birth based on pre-pregnancy body mass index (BMI) stratification and explore the associated factors of preterm birth among pregnant women at different BMI stratifications. Methods: From February 2018 to December 2020, pregnant women who participated in China Birth Cohort Study (CBCS) and gave birth at Beijing Obstetrics and Gynecology Hospital were enrolled as the study subjects. Electronic Data Capture System and standard structured questionnaires were used to collect data related to pre-pregnancy, pregnancy, and delivery for pregnant women. Pregnant women were divided into the low-weight group, normal-weight group and overweight group based on their pre-pregnancy BMI. A Cox proportional hazards model was used to analyze the associated factors of preterm birth among pregnant women with different BMI before pregnancy. Results: A total of 27 195 singleton pregnant women were included, with a preterm birth rate of 5.08% (1 381/27 195). The preterm birth rates in the low-weight group, normal-weight group and overweight group were 4.29% (138/3 219), 4.63% (852/18 390) and 7.00% (391/5 586) respectively (P<0.001). After adjusting for relevant factors, the Cox proportional hazards model showed that the risk of preterm birth in the overweight group was 1.457 times higher than that in the normal-weight group (95%CI: 1.292-1.643). Preeclampsia-eclampsia (HR=2.701, 95%CI: 1.318-5.537) was the associated factor for preterm birth in the low-weight group. Advanced maternal age (HR=1.232, 95%CI: 1.054-1.441), history of preterm birth (HR=4.647, 95%CI: 3.314-6.515), vaginal bleeding in early pregnancy (HR=1.613, 95%CI: 1.380-1.884), and preeclampsia-eclampsia (HR=3.553, 95%CI: 2.866-4.404) were associated factors for preterm birth in the normal-weight group. Advanced maternal age (HR=1.473, 95%CI: 1.193-1.818), history of preterm birth (HR=3.209, 95%CI: 1.960-5.253), vaginal bleeding in early pregnancy (HR=1.636, 95%CI: 1.301-2.058), preeclampsia-eclampsia (HR=2.873, 95%CI:2.265-3.643), and pre-gestational diabetes mellitus (HR=1.867, 95%CI: 1.283-2.717) were associated factors for preterm birth in the overweight group. Conclusion: Pre-pregnancy overweight is an associated factor for preterm birth, and there are significant differences in the associated factors of preterm birth among pregnant women with different BMI before pregnancy.

Pattern of liver enzymes and maternal outcome in eclamptic patients admitted to the Intensive Care Unit, University College Hospital, Nigeria

Introduction: Eclampsia, a hypertensive disorder, is one of the leading causes of maternal mortality in developing countries like Nigeria. We evaluated the relationship between the pattern of liver enzymes and maternal mortality in eclamptic women. Method: A retrospective study of 55 eclamptic women admitted to the Intensive Care Unit (ICU), University College Hospital, Nigeria, was conducted. Data were obtained on their demographic, obstetric, and clinical characteristics, liver enzyme patterns, and maternal outcome. Analysis was by descriptive statistics, univariate analysis, and non-parametric tests with level of significance set at p<0.05. Results: Maternal deaths occurred in 27.3% and elevation of liver enzymes was observed more among the dead patients compared with those who survived. Alanine aminotransferase (ALT) was the most commonly elevated liver enzyme, occurring in almost all (90.9%) the patients. Maternal mortality was significantly associated with age (p=0.001), saturated oxygen levels (p=0.007), elevated alkaline phosphatase (p=0.008), alanine aminotransferase (p=0.013), aspartate aminotransferase (p=0.016), and total bilirubin (p<0.001). Conclusion: Maternal mortality due to eclampsia was clinically associated with age, elevated liver enzymes and a lower serum level of total bilirubin. Liver transaminases are therefore important prognostic indicators associated with eclampsia.

Aspects cliniques et évolutifs de la pré-éclampsie sévère traitée à la maternité Befelatanana, Madagascar / Clinical aspects and outcome of severe pre-eclampsia treated at the Befelatanana maternity hospital, Madagascar

Pre-eclampsia is a major public health problem and is one of the main causes of maternal-fetal morbidity. The main objective of this study is to describe the clinical and evolutionary aspects of severe pre-eclampsia. Methods: This was a retrospective, monocentric, descriptive, observational and cross-sectional study of 6 months, from January 01, 2019 to June 30, 2019, conducted at the level of the resuscitation service of the university hospital of gynecology obstetrics Befelatanana (CHU GOB). Results: Three hundred and fourteen (5.10%) cases out of 6153 admissions of severe pre-eclampsia were collected in the study; the average age was 27.29 ±7.47 years. Eclampsia (30.25%, n= 95), retroplacental hematoma (13.38%, n= 42) and acute renal failure (7.96%, n= 25) were the most frequent maternal complications. Maternal prognosis was favorable in 92.36% of cases (n= 290). Maternal death represented 3.18% (n= 10). Prematurity (44.82%, n= 95), fetal hypotrophy (37.26%, n= 79) and fetal asphyxia (14.15%, n= 30) were the most common fetal complications. Fetal death was 26.47% (n= 81). Conclusion: It is necessary to reinforce the information and education of parturients on the first signs for an early detection, diagnosis and management

Les facteurs associés aux morbi-mortalités maternelles de l'éclampsie à la maternité de Befelatanana / Factors associated with maternal eclampsia morbidity and mortality at the maternity hospital of Befelatanana

L'éclampsie est une complication neurologique majeure de la pré-éclampsie sévère, responsable d'une lourde morbidité et mortalité maternelle. L'objectif de cette étude était de déterminer les facteurs associés aux morbimortalités maternelles de l'éclampsie. Patients et Méthodes : Il s'agissait d'une étude rétrospective, transversale, descriptive et analytique ; sur une période de 36 mois, allant de Janvier 2019 à Décembre 2021, réalisée à la maternité de Befelatanana.

Tendência da mortalidade materna (2022-2030): uma análise baseada em séries temporais / Maternal mortality trend (2022-2030): an analysis based on time series

A morte materna é definida como aquela que ocorre, por qualquer causa na gravidez, parto ou puerpério (até 42 dias após o parto), ou até 1 ano, por causas obstétricas. A maioria destes óbitos poderiam ser evitadas com estratégias de cuidado voltadas para as principais causas de óbitos. Sendo assim, este Relatório de Tendência de Indicadores Estratégicos analisa a série histórica de RMM (Razão da Mortalidade Materna) com a finalidade de traçar sua tendência até 2030 para o nível estadual, identificar os principais grupos de morbidades que provocam os óbitos maternos na série histórica 2011-2021 e avaliar o impacto dos óbitos que tiveram a COVID-19 como informação da causa da morte entre os óbitos ocorridos nos anos de 2020 e 2021

Maternal death is defined as that which occurs, from any cause during pregnancy, childbirth or the postpartum period (up to 42 days after birth), or up to 1 year, due to obstetric causes. The majority of these deaths could be avoided with care strategies aimed at the main causes of death. Therefore, this Strategic Indicator Trend Report analyzes the historical series of MMR (Maternal Mortality Ratio) with the purpose of tracing its trend until 2030 at the state level; identify the main groups of morbidities that cause maternal deaths in the 2011-2021 historical series and assess the impact of deaths caused by COVID-19 as information on the cause of death among deaths occurring in the years 2020 and 2021

Prevalence of Preeclampsia in Brazil: An Integrative Review / Prevalência de pré-eclâmpsia no Brasil: Uma revisão integrativa

Abstract Objective To review literature and estimate the occurrence of preeclampsia and its complications in Brazil. Methods We performed an integrative review of the literature, and included observational studies published until August 2021 on the SciELO and PubMed databases that evaluated preeclampsia among pregnant women in Brazil. Other variables of interests were maternal death, neonatal death, hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome, and eclampsia. Three independent reviewers evaluated all retrieved studies and selected those that met inclusion criteria. A metanalysis of the prevalence of preeclampsia and eclampsia was also performed, to estimate a pooled frequency of those conditions among the studies included. Results We retrieved 304 studies after the initial search; of those, 10 were included in the final analysis, with a total of 52,986 women considered. The pooled prevalence of preeclampsia was of 6.7%, with a total of 2,988 cases reported. The frequency of eclampsia ranged from 1.7% to 6.2%, while the occurrence of HELLP syndrome was underreported. Prematurity associated to hypertensive disorders ranged from 0.5% to 1.72%. Conclusion The frequency of preeclampsia was similar to that reported in other international studies, and it is increasing in Brazil, probably due to the adoption of new diagnostic criteria. The development of a national surveillance network would be essential to understand the problem of hypertensive disorders of pregnancy in Brazil.

Resumo Objetivo Revisar a literatura e estimar a ocorrência de pré-eclâmpsia e suas complicações no Brasil. Métodos Foi realizada uma revisão integrativa da literatura, com a inclusão de estudos observacionais publicados até agosto de 2021, nas bases de dados PubMed e SciELO, que avaliavam pré-eclâmpsia em mulheres brasileiras. Outras variáveis de interesse foram morte materna, morte neonatal, síndrome de hemólise, enzimas hepáticas elevadas e plaquetopenia (hemolysis, elevated liver enzymes, and low platelet count, HELLP, em inglês) e eclâmpsia. Três revisores independentes avaliaram os estudos identificados e selecionaram aqueles que preenchiam os critérios de inclusão. Foi realizada uma meta-análise da prevalência de pré-eclâmpsia e eclâmpsia, para estimar sua frequência acumulada com relação aos estudos incluídos. Resultados Foram identificados 304 estudos, 10 dos quais foram incluídos na análise final, num total de 52.986 mulheres. A frequência acumulada de pré-eclâmpsia foi de 6,7%, com um total de 2.988 casos. A frequência de eclâmpsia variou de 1,7% a 6,2%, ao passo que a ocorrência de síndrome de HELLP foi pouco relatada. A prematuridade associada a hipertensão foi de 0,5% a 1,7%. Conclusão A frequência de pré-eclâmpsia foi similar à de estudos internacionais; no entanto, ao longo dos últimos anos, ela vem aumentando no Brasil, possivelmente como reflexo da adoção de novos critérios diagnósticos. A criação de uma rede nacional de vigilância seria fundamental para entender o problema da hipertensão na gestação no país.

Objective:To evaluate factors associated with Pregnancy-related KidneyInjury(PRAKI) inwomen admitted to high dependency care unit at Women and Newborn Hospital in Lusaka, ZambiaMethodology:This was an unmatched case-control study conducted in the high-dependency care unit at Women and Newborn Hospital in Lusaka. Study participantswererecruitedconsecutivelybyconveniencesampling.Participants'medicalrecords were reviewed to capture serum creatinine levels;whileastructuredquestionnairewasadministeredto eligible andconsentedstudy participants to capture data on sociodemographic, obstetric, and medical factors. Serum creatinine levels above 84µmol/l were used as criteria for classifying PRAKI. Excel was used for data cleaningandStatav13usedforanalysis.Descriptive statistics were done for all variables followed by univariate and multivariable logistic regression to determine association. 95% CI was usedand p value of<0.05 was consideredsignificant.Results:Thestudy comprised of185 study participants, split into 85 women with PRAKI (cases) and 100 women without PRAKI (controls). The median age was 29 years with 11years interquartile range. 75.3%of the study participants wereinmarriagerelationships.Pre-existinghypertension was the most prevalent medical condition in both the cases (51.8%) and the controls (38%). Sickle celldisease was much less common at 1.2% in cases and 8% in controls. Among the obstetric conditions, preeclampsia was the most common condition at 77.6% and 60% in cases and controls respectively. Eclampsia was found in 38.8% of cases and 11% of controls. Sepsis was least common at 4.7% of cases. This study found that obstetricfactorssuch as eclampsia (AOR = 5.12, 95% CI [2.14 ­ 12.23]; p≤0.0001), preeclampsia (AOR = 2.46, 95% CI [1.12 ­ 5.39]; p = 0.025), and postpartum haemorrhage were associated with the development of PRAKI. Medical conditions were not associated with PRAKI.

A propósito de un caso de desprendimiento seroso de retina en una paciente con preeclampsia severa / Apropos of a case of serous retinal detachment in a patient with severe preeclampsia

Objetivo: Presentar las características clínicas y las secuelas de un caso de desprendimiento de retina (DR) seroso en preeclampsia. Diseño del estudio: Observacional. Material y métodos: Mujer de 17 años, embarazada de 36 semanas, presentó tres días previos a la visita oftalmológica disminución de la agudeza visual de ambos ojos, así como dolor abdominal. A su llegada se diagnosticó preeclampsia con datos de gravedad, por lo que se decidió interrumpir el embarazo. Su agudeza visual de ambos ojos fue contar los dedos a 50 centímetros. El examen de fondo de ojo derecho reveló un DR inferior y temporal, también líquido que se extendía hacia la mácula. El ojo izquierdo se observa con DR superior, nasal y temporal. Se decide iniciar tratamiento con esteroides, presentando mejoría visual y anatómica al tercer día. Conclusiones: El diagnóstico oportuno y seguimiento son el pilar para tener un buen pronóstico visual en pacientes con preeclampsia.

Objective: To present clinical characteristics and the sequelae of a case of serous retinal detachment in preeclampsia. Study design: Observational. Material and methods: We presented a 17-year old, 36-weeks pregnant, female without other ocular history, who reported 3 days previous of the ophthalmologic visit a reduction in visual acuity of both eyes, as well as abdominal pain. Upon arrival, preeclampsia was diagnosed with severity data, so was decided to terminate the pregnancy by cesarean. On examination, her visual acuity of both eyes was counting fingers at 50 centimeters. Fundus examination of the right eye revealed an inferior and temporal retinal detachment, also fluid extending into the macula. The left eye was observed with a superior, nasal and temporal detachment. It was decided to start steroid treatment, presenting visual and anatomical improvement. Conclusions: Timely diagnosis and follow-up are the pillar to have a good visual prognosis in preeclampsia

Risk factors for preeclampsia and eclampsia in Sidama region, southern Ethiopia: a nested case-control study

Introduction: though Ethiopia has made a significant improvement in the reduction of maternal mortality, the high burden of preeclampsia remains a concern in the Sidama region of southern Ethiopia. This study aimed to determine the risk factors for preeclampsia and eclampsia in the Sidama region of southern Ethiopia. Methods: a nested case-control study was conducted from August 8, 2019, to October 1, 2020 in the Sidama region. Two-stage sampling techniques were used to recruit study participants. First, seven of the 13 public hospitals were selected using a random sampling technique. Second, cases and controls were selected from a cohort of pregnant women enrolled at ≥20 weeks of gestation up until the 37th week. Data were collected in a face-to-face interview using a locally translated and validated tool. Binary logistic regression analysis was used to identify risk factors for preeclampsia and eclampsia Results: of the planned sample size of 816 women, we enrolled 808 (404 cases and 404 controls). Of the 404 cases, (59.40%, 240/404) had preeclampsia without severity features, (30.94%, 125/404) had preeclampsia with severity features, and (9.65%, 39/404) had convulsions. After controlling for confounders, women having a low wealth status were 98% [AOR: 1.98, 95%CI: 1.34-2.92] at higher risk for preeclampsia and eclampsia compared to women having a high wealth status. Women who had early neonatal deaths were 5 times more likely to be developed preeclampsia and eclampsia than women who did not have early neonatal deaths [AOR: 5.09, 95%CI: 1.69-9.36]. Women who did not attend school were three times more likely to develop preeclampsia and eclampsia [AOR: 3.00, 95% CI: 1.10-8.19] compared to women who attended college/university. Conclusion: in this study, a higher risk for preeclampsia and eclampsia was observed among women with low wealth status, women who had early neonatal deaths and women who did not attend school. Some of these factors could be positively influenced by educational interventions. Maternal and child health providers should screen pregnant women at risk for preeclampsia and eclampsia using these factors. Findings of this study will provide epidemiological evidence for policy makers and implementers to reduce the occurrence of preeclampsia and eclampsia.

Retinal changes among pre-eclamptic patients in University of Benin Teaching Hospital, Benin, Nigeria

Background: Preeclampsia is one of the hypertensive disorders in pregnancy that contributes significantly to maternal and fetal morbidity and mortality, with the impact felt more in developing countries. It is characterized by endothelial dysfunction and vasospasm of vessels which can be observed by an ocular fundal examination. The aim of this study was to determine the ocular fundus findings of women with preeclampsia. Methods: This was a cross-sectional study, carried out at the University of Benin Teaching Hospital involving a total of 220 pregnant women. The women were divided into two groups of 110 pregnant women (A&B).Their Age and Gestational age was cross-matched and retinopathy graded according to Keith and Wagner classification. Group A was made up of Preeclamptic women and Group B was made up of healthy pregnant women. Visual acuity was measured using Snellens' chart, and the fundus was examined with direct ophthalmoscope. Results: This showed that the retinal changes observed in the preeclamptic women were associated with their age (P = 0.009), gestational age (P = 0.044), blood pressure (P = 0.001), Proteinuria (P = 0.001), Severity of the disease (P = 0.001), visual acuity (P = 0.035) as well as with the visual symptoms (P = 0.001) but not statistically significant with the gravida (P = 0.799). Conclusion: Our study highlights the importance of timely ophthalmoscopy which helps to assess severity of disease (pre-eclampsia) which affects the decision of induction of delivery to predict and prevent possible complications which in turn immensely helps in judicious management of disease. Also, the study revealed that preeclamptic women who are multigravida are more likely to have retinopathy than primigravid

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.
