RESUMO
BACKGROUND: Cardiovascular disease is the leading cause of mortality in women. Pregnancy is an ideal period to implement cardiovascular prevention strategies as women seek medical help. We aimed to develop a predictive model to identify women at increased risk for chronic hypertension (CH) based on information collected in the index pregnancy. METHODS: Cohort of 26â 511 women seen in 2 consecutive pregnancies. Included were women without CH, with information on maternal characteristics and blood pressure at 11 to 13 weeks' gestation, and the development of preeclampsia or gestational hypertension (GH) in the index pregnancy. Logistic regression models were fitted for the prediction of the development of future CH by the 20th week of the subsequent pregnancy. The performance of screening and risk calibration of the model were assessed. RESULTS: In this study 1560 (5.9%) women developed preeclampsia or GH (index pregnancy), and 215 (0.8%) developed future CH, with a median of 3.0 years later. Predictors of development of future CH were maternal age, weight, and blood pressure; Black and South Asian ethnicity; family history of preeclampsia; parity; and development of preeclampsia or GH. Preeclampsia or GH detected 52.1% (45.2%-58.9%) of future CH. At a screen-positive rate of 10%, a model including maternal characteristics, early pregnancy blood pressure, and development of preeclampsia or GH detected 73.5% (67.1-79.3) of future CH. CONCLUSIONS: Early pregnancy maternal characteristics, blood pressure, and development of preeclampsia or GH identify three-fourths of women at risk for future CH. Our results offer an important preventative strategy for identifying women at increased risk of future CH, which is applicable worldwide.

Background: This study aims to observe how auriculotherapy acts as a nonpharmacological treatment for pregnant women's gestational hypertension. Materials and Methods: This study was a randomized controlled trial. Eighty patients were with gestational hypertension recruited and divided into control (n = 40) and intervention (n = 40) groups. The control group just received the usual perinatal care. The intervention group received one month of auriculotherapy in addition to the usual care. Blood pressure was measured before and 15 minutes after rest in both groups twice a week. The data were analyzed using descriptive statistics and inferential tests. Results: The mean systolic blood pressure, based on the Mann-Whitney test, was not statistically significant between the two groups before the intervention and in the first two weeks after the intervention (p >0.05); however, after the third week of intervention, the mean systolic blood pressure in the intervention group was significantly lower than that in the control group (p <0.001). As per the Mann-Whitney test, the mean diastolic blood pressure was not statistically significant between the two groups before the intervention and the first week after the intervention (p <0.05). However, after the second week of intervention, the mean diastolic blood pressure in the intervention group was significantly lower than that in the control group, and this decrease was highest in the fourth week of the intervention (p <0.001). Conclusions: This study demonstrated that auriculotherapy would reduce blood pressure in pregnant women suffering from hypertension.
RESUMO
BACKGROUND: Although smoking cigarettes has been shown to have a protective effect on preeclampsia, quitting smoking also results in weight gain. Weight gain leading to an obese body mass index is a risk factor for hypertensive disorders of pregnancy (HDP). METHODS: The objective of this study was to explore the relationship between smoking status, body mass index, and gestational weight gain on the risk of HDP. A cross-sectional analysis was performed utilizing US birth certificate data. We examined HDP risks in relation to maternal smoking, body mass index, and gestational weight gain. Associations were expressed as rate ratios with 95% CIs and adjusted for potential confounders. Clinically important outcomes of smoking throughout pregnancy were also evaluated. RESULTS: Of the 22 191 568 women studied, HDP rates among nonsmokers, those who quit smoking, and persistent smokers were 6.8%, 8.6%, and 7.0%, respectively. The rate ratio of HDP was higher for women who quit smoking, especially evident among those with excessive gestational weight gain. Corrections for exposure misclassification and unmeasured confounding strengthened the associations among women who quit smoking. There was an almost 6-fold increase in the rate of stillbirth for persistent smokers (2.3%) compared with those who quit smoking (0.4%) and nonsmokers (0.4%). CONCLUSIONS: Women who quit smoking during pregnancy were more likely to gain excessive weight and develop HDP. Although quitting smoking during pregnancy may be associated with an increase in the risk of HDP, it is also associated with a reduced risk of stillbirth. Pregnant women counseled to quit smoking should also receive counseling on nutrition and exercise to prevent excessive gestational weight gain.

BACKGROUND: Hypertensive disorders of pregnancy (HDP) are associated with subsequent adverse cardiac remodeling and cardiovascular disease. The role of myocardial microvascular disease among individuals with HDP and left ventricular (LV) remodeling as a potential link to cardiovascular disease is unknown. We aimed to determine whether individuals with HDP history have coronary microvascular dysfunction measured by coronary flow reserve 8 to 10 years after delivery and whether microvascular dysfunction correlates with LV remodeling. METHODS: Individuals with pregnancies delivered from 2008 to 2010 underwent burst-replenishment myocardial contrast echocardiography (2017-2020) to quantify myocardial perfusion at rest and during dobutamine stress. Video intensity versus time data were used to derive ß, the rate of rise of video intensity, a correlate for myocardial blood flow. Coronary flow reserve was calculated as the ratio of ß at peak stress to ß at rest, averaged across LV myocardial regions of interest. RESULTS: We studied 91 individuals (aged 38±6 and 9.1±0.9 years postdelivery) and 19 with a history of HDP. Individuals with coronary microvascular dysfunction (coronary flow reserve <2.0; n=13) had a higher proportion of HDP (46.2% versus 16.7%; P=0.026) and higher prepregnancy body mass index, baseline heart rate, and hemoglobin A1c compared with those without microvascular dysfunction. The association of coronary flow reserve and HDP was attenuated after adjusting for cardiometabolic factors (P=0.133). In exploratory subgroup analyses, individuals with both LV remodeling (relative wall thickness >0.42) and HDP (n=12) had the highest proportion of microvascular dysfunction (41.7% versus +HDP-LV remodeling [n=7] 14.3%; -HDP+LV remodeling [n=26] 7.7%; P=0.0498). CONCLUSIONS: In this small study, HDP history is associated with coronary microvascular dysfunction 1 decade after delivery, findings that may, in part, be driven by metabolic factors including obesity and diabetes. Microvascular dysfunction may contribute to cardiovascular disease among individuals with a history of HDP.

BACKGROUND: To understand the role of hypertensive disorders of pregnancy (HDP), including preeclampsia and gestational hypertension (GH), in brain health earlier in life, we investigated the association of HDP with midlife cognition and brain health. METHODS: We studied a prospective cohort of women, baseline age 18 to 30 years, who were assessed at study years 25 and 30 with a cognitive battery and a subset with brain magnetic resonance imaging. A history of HDP was defined based on self-report. We conducted linear regression to assess the association of a history of preeclampsia, GH, or no HDP with cognition and brain magnetic resonance imaging white matter hyperintensities. RESULTS: Among 1441 women (mean age, 55.2±3.6 years), 202 reported preeclampsia and 112 reported GH. GH was associated with worse cognitive performance: global cognition (mean score, 23.2 versus 24.0; P=0.018), processing speed (67.5 versus 71.3; P=0.01), verbal fluency (29.5 versus 31.1; P=0.033), and a trend for executive function (24.3 versus 22.6; P=0.09), after multivariable adjustment. GH was associated with a greater 5-year decline in processing speed (mean change, -4.9 versus -2.7; P=0.049) and executive function (-1.7 versus 0.3; P=0.047); preeclampsia was associated with a greater 5-year decline on delayed verbal memory (-0.3 versus 0.1; P=0.041). GH and preeclampsia were associated with greater white matter hyperintensities in the parietal and frontal lobes, respectively. CONCLUSIONS: GH and preeclampsia are associated with cognition and white matter hyperintensities during midlife, with differences in cognitive domains and brain lobes. Women with HDP may need to be closely monitored for adverse brain outcomes starting in midlife.
RESUMO
Background: Whether remote blood pressure (BP) monitoring can decrease racial disparities in BP measurement during pregnancy and the postpartum period remains unclear. This study evaluated whether Black and White patients enrolled in the Connected Maternity Online Monitoring (CMOM) program showed improvements in BP ascertainment and interval. Methods: A retrospective cohort of 3,976 pregnant patients enrolled in CMOM were compared to matched usual care patients between January 2016 and September 2022 using electronic health record data. The primary outcomes were BP ascertainment (number of BP measurements) and BP interval (time between BP measurements) during pregnancy and the postpartum period. The proportion of patients with a hypertensive disorder of pregnancy who checked their BP within 7 days of discharge following delivery was also assessed. Results: Enrollment in CMOM was lower among Black patients than White patients (42.1% vs 54.7%, P<0.0001). Patients in the CMOM group had more BP measurements than patients in the usual care group during pregnancy (rate ratio=1.78, 95% CI 1.74-1.82) and the postpartum period (rate ratio=1.30, 95% CI 1.23-1.37), with significant improvements for both Black and White patients enrolled in CMOM compared to patients in usual care. The CMOM intervention did not result in an improvement in 7-day postpartum adherence to checking BP for Black patients (risk ratio=1.03, 95% CI 0.94-1.11) as it did for White patients (risk ratio=1.09, 95% CI 1.01-1.17). Conclusion: Remote BP monitoring programs are a helpful tool to improve the frequency of BP measurements and shorten intervals between measurements during the prenatal and postpartum periods for all patients. Future evaluation is needed to determine the barriers to offering the program to and enrolling Black patients.

ABSTRACT Objective This study aimed to evaluate the prevalence of hypertensive disorders during pregnancy among Brazilian women with preterm births and to compare the epidemiological characteristics and perinatal outcomes among preterm births of women with and without hypertension. Methods This was a secondary cross-sectional analysis of the Brazilian Multicenter Study on Preterm Birth. During the study period, all women with preterm births were included and further split into two groups according to the occurrence of any hypertensive disorder during pregnancy. Prevalence ratios were calculated for each variable. Maternal characteristics, prenatal care, and gestational and perinatal outcomes were compared between the two groups using χ2 and t-tests. Results A total of 4,150 women with preterm births were included, and 1,169 (28.2%) were identified as having hypertensive disorders. Advanced maternal age (prevalence ratio (PR) 2.49) and obesity (PR= 2.64) were more common in the hypertensive group. The gestational outcomes were worse in women with hypertension. Early preterm births were also more frequent in women with hypertension. Conclusion Hypertensive disorders of pregnancy were frequent among women with preterm births, and provider-initiated preterm births were the leading causes of premature births in this group. The factors significantly associated with hypertensive disorders among women with preterm births were obesity, excessive weight gain, and higher maternal age.

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

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.
RESUMO
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.
RESUMO
Resumen OBJETIVO: Describir y comparar las características obstétricas de pacientes puérperas, con anemia, con finalización del embarazo por parto o cesárea. MATERIALES Y METODOS: Estudio retrospectivo, observacional, descriptivo y comparativo de pacientes con anemia en el puerperio de parto y de cesárea atendidas en el Hospital de Lircay de Huancavelica en el año 2020. Se aplicó la técnica del análisis documental y el instrumento fue una ficha de recolección de datos. RESULTADOS: Se analizaron 162 partos y 46 cesáreas. En las características patológicas se encontró una diferencia significativa: anemia en el embarazo (112 de 162; 69.1% posparto y 23 de 46 [50% de poscesárea]), trastornos hipertensivos (4 de 162; 2.5% postparto y 8 de 46 [7.4% de poscesárea]), hemorragias de la segunda mitad del embarazo (2 de 162 [1.2% de postparto] y 4 de 46 [8.7% poscesárea]). En cuanto al grado de anemia se encontró diferencia significativa en ambos grupos en relación con el grado moderado (89 de 162 [54.9%] postparto y 33 de 46 [71.7%] en poscesárea). CONCLUSIONES: En la frecuencia de anemia puerperal se encontró una diferencia conforme al tipo de finalización del embarazo. La edad, grado de escolaridad, anemia gestacional, trastorno hipertensivo, hemorragia de la segunda mitad de embarazo y la placenta previa se identificaron como factores con diferencias significativas en la anemia, según el tipo de finalización del embarazo.
Abstract OBJECTIVE: To describe and compare the obstetric characteristics of postpartum patients with anemia, with termination of pregnancy by delivery or cesarean section. MATERIALS AND METHODS: Retrospective, observational, descriptive and comparative study of patients with anemia in the postpartum period after childbirth and cesarean section attended at the Lircay Hospital in Huancavelica in 2020. The documentary analysis technique was applied and the instrument was a data collection form. RESULTS: A total of 162 deliveries and 46 cesarean sections were analyzed. In the pathological characteristics a significant difference was found: anemia in pregnancy (112 of 162; 69.1% postpartum and 23 of 46 [50% post cesarean]), hypertensive disorders (4 of 162; 2.5% postpartum and 8 of 46 [7.4% post cesarean]), hemorrhages in the second half of pregnancy (2 of 162 [1.2% postpartum] and 4 of 46 [8.7% post cesarean]). Regarding the degree of anemia, a significant difference was found in both groups in relation to moderate degree (89 of 162 [54.9%] postpartum and 33 of 46 [71.7%] postcesarean section). CONCLUSIONS: In the frequency of puerperal anemia, a difference was found according to the type of termination of pregnancy. Age, level of education, gestational anemia, hypertensive disorder, hemorrhage in the second half of pregnancy and placenta previa were identified as factors with significant differences in anemia, according to the type of termination of pregnancy.
RESUMO
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.

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 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.

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.
RESUMEN Objetivo. Estimar la prevalencia puntual y los rangos probables de hipertensión provocada por embarazo, preeclampsia, diabetes gestacional, peso bajo al nacer y parto prematuro en América Latina y el Caribe, y evaluar la heterogeneidad de las estimaciones. Métodos. Se llevó a cabo una revisión sistemática y metanálisis de los estudios de observación que notificaron la prevalencia de resultados adversos perinatales y maternos en poblaciones de América Latina y el Caribe, publicados entre los años 2000 y 2019 en inglés, español o portugués. Se realizaron búsquedas en PubMed, Embase y LILACS. Se estimó la prevalencia puntual y se evaluó la heterogeneidad general y, en los análisis de subgrupos, la heterogeneidad según el diseño del estudio y nivel de sesgo. Resultados. De 1 087 registros recuperados, se incluyeron 50 artículos en la revisión: 2 sobre los trastornos hipertensivos en el embarazo, 14 sobre preeclampsia, 6 sobre la diabetes gestacional, 9 sobre peso bajo al nacer y 19 sobre parto prematuro. No se pudo realizar ningún metanálisis de los trastornos hipertensivos del embarazo debido al número reducido de estudios. Las estimaciones de prevalencia puntual y los intervalos de confianza (IC) del 95% para la preeclampsia, la diabetes gestacional, el peso bajo al nacer y el parto prematuro fueron: 6,6% (IC de 95%: 4,9%, 8,6%), 8,5% (IC de 95%: 3,9%, 14,7%), 8,5% (IC de 95%: 7,2%, 9,8%) y 10,0% (IC de 95%: 8,0%, 12,0%), respectivamente. Se observó una heterogeneidad significativa en general, así como según el diseño del estudio. No se advirtieron grandes diferencias en las estimaciones según el nivel del sesgo. Conclusiones. Los resultados de este estudio ofrecen cálculos actualizados de algunos de los resultados adversos perinatales y del embarazo con mayor prevalencia en América Latina y el Caribe. Estos resultados ponen de manifiesto que existe una gran heterogeneidad en las estimaciones de prevalencia, que podría reflejar la diversidad de la población de la región.
RESUMO Objetivo. Estimar a prevalência pontual e os intervalos prováveis de hipertensão induzida pela gravidez, pré-eclâmpsia, diabetes gestacional, baixo peso ao nascer e parto prematuro na América Latina e no Caribe e avaliar a heterogeneidade das estimativas. Métodos. Realizou-se uma revisão sistemática com metanálise de estudos observacionais que relatam a prevalência de desfechos maternos e perinatais adversos em populações da América Latina e do Caribe, publicados entre 2000 e 2019 em inglês, espanhol ou português. Os bancos de dados PubMed, Embase e LILACS foram pesquisados. Estimou-se a prevalência pontual e avaliou-se a heterogeneidade geral, bem como, em análises de subgrupo, a heterogeneidade por delineamento do estudo e o nível de viés. Resultados. De 1 087 registros encontrados, 50 artigos foram incluídos na revisão: dois sobre distúrbios hipertensivos da gravidez, 14 sobre pré-eclâmpsia, seis sobre diabetes gestacional, nove sobre baixo peso ao nascer e 19 sobre parto prematuro. Não foi possível realizar metanálise para distúrbios hipertensivos da gravidez devido ao pequeno número de estudos. As estimativas de prevalência pontual e intervalos de confiança de 95% (IC) para pré-eclâmpsia, diabetes gestacional, baixo peso ao nascer e parto prematuro foram: 6,6%; (IC 95%: 4,9-8,6%), 8,5% (IC 95%: 3,9-14,7%), 8,5% (IC 95%: 7,2-9,8%) e 10,0% (IC 95%: 8,0-12,0%), respectivamente. Observou-se heterogeneidade considerável, tanto em geral como por delineamento de estudo. Não foram observadas diferenças importantes nas estimativas por nível de viés. Conclusões. Os resultados deste estudo fornecem estimativas atualizadas de alguns dos desfechos gestacionais e perinatais adversos mais prevalentes na América Latina e no Caribe. Destacam a existência de uma importante heterogeneidade nas estimativas de prevalência, o que pode refletir a diversidade das populações da região.
RESUMO
Introdução: A hipertensão arterial na gestação preditor de baixo peso ao nascer. Objetivo: Investigar a associação entre hipertensão arterial materna e o peso ao nascer inferior a 3.000g, entre indivíduos a termo. Método: Estudo tipo casocontrole, realizado em Juazeiro Bahia e Petrolina Pernambuco, entre 2009 e 2011. Calculouse Odds Ratio e intervalos de confiança de 95% na análise de dados. Resultados: Gestantes com hipertensão tiveram 49% de chance a mais de ter filhos com peso inferior a 3.000g, quando comparadas às sem hipertensão arterial. Conclusão: A identificação precoce da hipertensão arterial na gestação evita danos desse agravo, especialmente baixo peso ao nascer.
