Abstract
OBJECTIVES Among many risk factors for preeclampsia (PE), prepregnancy body mass index (BMI) is one of few controllable factors. However, there is a lack of stratified analysis based on the prepregnancy BMI. This study aimed to determine the influencing factors for PE and assess the impact of PE on obstetric outcomes in twin pregnancies by prepregnancy BMI. METHODS This was a retrospective cohort study between January 1, 2017, and December 31, 2022, in Southwest China. Impact factors and associations between PE and obstetric outcomes were analyzed separately for twin pregnancies with prepregnancy BMI < 24kg/m2 (non-overweight group) and BMI ≥ 24kg/m2 (overweight group). RESULTS In total, 3602 twin pregnancies were included, of which, 672 women were allocated into the overweight group and 11.8% of them reported with PE; 2930 women were allocated into the non-overweight group, with a PE incidence of 5.6%. PE had a negative effect on birthweight and increased the incidence of neonatal intensive care unit admission in both the overweight and non-overweight groups (43.0% vs. 28.0%, p = .008; 45.7% vs. 29.1%, p < .001). Among overweight women, PE increased the proportion of postpartum hemorrhage (15.2% vs. 4.4%, p < .001). After adjustments, multivariate regression analysis showed that excessive gestational weight gain (aOR = 1.103, 95% CI: 1.056-1.152; aOR = 1.094, 95% CI: 1.064-1.126) and hypoproteinemia (aOR = 2.828, 95% CI: 1.501-5.330; aOR = 6.932, 95% CI: 4.819-9.971) were the shared risk factors for PE in both overweight and non-overweight groups. In overweight group, in vitro fertilization was the other risk factor (aOR = 2.713, 95% CI: 1.183-6.878), whereas dichorionic fertilization (aOR = 0.435, 95% CI: 0.193-0.976) and aspirin use during pregnancy (aOR = 0.456, 95% CI: 0.246-0.844) were protective factors. Additionally, anemia during pregnancy (aOR = 1.542, 95% CI: 1.090-2.180) and growth discordance in twins (aOR = 2.451, 95% CI: 1.215-4.205) were connected with an increased risk of PE only in non-overweight twin pregnancies. CONCLUSIONS Both discrepancy and similarity of impact factors on developing PE were found between overweight and non-overweight twin pregnancies in this study. However, the dosage and initiation time of aspirin, as well as twin chorionicity on the occurrence of PE in two subgroups, are still debated.

Abstract
Ethiopia has made improvements in the reduction of maternal mortality; the high burden of preeclampsia remains a concern in the Sidama region. This study aimed to measure the effect of preeclampsia on adverse maternal outcomes and identify risk factors among women with preeclampsia in Sidama region. A prospective open cohort study was conducted from August 8, 2019, to October 1, 2020. We enrolled a total of 1015 the pregnant women who had preeclampsia and normotensive women at ≥ 20 weeks of gestation and followed them until 42 days after delivery. A log-binomial logistic regression model was used to estimate the incidence of adverse maternal outcomes and its risk factors. There were 276 adverse maternal outcomes observed in the preeclampsia group compared to 154 adverse maternal outcomes in the normotensive group (P < 0.001). Women with severe features of preeclampsia had a 43% (aRR = 1.43, 95% CI 1.3-1.58) higher risk for adverse maternal outcomes compared to women without severe features of preeclampsia. Women without severe features of preeclampsia had a 39% (aRR = 1.39, 95% CI 1.2-1.76) higher risk for adverse maternal outcomes compared to women in the normotensive group. More adverse maternal outcomes occurred among women with preeclampsia after controlling for confounders.

BMC Pregnancy Childbirth 2022; 22:830. [PMID: 36357833 PMCID: PMC9650878 DOI: 10.1186/s12884-022-05184-y] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Accepted: 11/05/2022] [Indexed: 11/12/2022] Open
Abstract
Background Both in vitro fertilization (IVF) and preeclampsia (PE) were associated with placental dysfunction. Although IVF can increase the incidence of PE, the pregnancy outcomes and risk factors for preeclampsia in dichorionic twin pregnancies conceived via IVF remain unclear. This study aimed to investigate the pregnancy outcomes and the risk factors for preeclampsia in dichorionic twin pregnancies conceived through IVF compared to those conceived after natural conception (NC). Methods This retrospective observational study enrolled 181 dichorionic twin pregnancy women with preeclampsia from 2016 to 2020. According to the mode of conception, they were allocated into IVF (n = 117) and NC groups (n = 64). The clinical characteristics of preeclampsia and pregnancy outcomes between the two groups were compared by using Student’s t test, chi-square test, and Fisher’s exact test, and logistic regression models were used to obtain adjusted odds ratios (aOR) with 95% confidence intervals (CI) for risk factors of early-onset preeclampsia. Results The incidence of early-onset PE and growth discordance in dichorionic twin pregnancies with PE is significantly higher in IVF-PE group than in NC group (78.60% vs 43.80%, P < 0.001, 11.10% vs 25.00%, P = 0.015). We found that IVF (aOR = 4.635, 95% CI: 2.130–10.084, P < 0.001) and growth discordance (aOR = 3.288; 95% CI: 1.090–9.749, P < 0.05) increased the incidence of early-onset PE. Conclusions In preeclamptic dichorionic twin pregnancies, IVF and growth discordance were associated with the increased incidence of early-onset PE. The underlying mechanism for the relationship between IVF and early-onset PE or growth discordance may be placental dysfunction.

Abstract
Despite immense global effort, the maternal mortality rate in low-resource settings remains unacceptably high. Globally, this reflects the grave inequalities in access to health and reproductive services. Pregnancy-associated acute kidney injury (PRAKI) is an independent risk factor for mortality. The reported incidence of PRAKI in low- and middle-income countries is higher than that of high-income countries (4%-26% versus 1%-2.8%, respectively). Hypertensive disorders are now the leading cause of PRAKI in many regions, followed by hemorrhage and sepsis. PRAKI in low-resource settings carries a high mortality for both mother and child. Outcome studies suggest that PRAKI is associated with residual kidney dysfunction and may lead to dialysis dependence. This can be a death sentence in many regions with limited kidney replacement therapy. This review will summarize data on PRAKI on the African, Latin American, and Asian continents over the past decade. It will include the progress in published data, mortality, and treatment interventions and provide recommendations for the next decade.

Development and external validation of a model for predicting adverse outcomes in women with preeclampsia: A retrospective study from two trans-regional centers in China. Pregnancy Hypertens 2021; 26:133-140. [PMID: 34794010 DOI: 10.1016/j.preghy.2021.10.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2021] [Revised: 08/12/2021] [Accepted: 10/22/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVES Preeclampsia is a common complication of pregnancy that causes health problems for both the mother and her fetus. This study aimed to develop and externally validate a model to predict adverse outcomes in preeclampsia in a trans-regional two-center retrospective cohort of Chinese women. STUDY DESIGN To generate a model for the risk of women with adverse outcomes, we incorporated candidate variables in the development set in univariate, least absolute shrinkage and selection operator analysis and multivariable logistic regression. The performance of the model was evaluated for the receiver operating characteristic (ROC) curve, calibration and decision curve analysis. Further, we externally validated the model in an independent dataset. MAIN OUTCOME MEASURES Composite adverse outcomes within 48 h of admission. RESULTS There were 1 783 and 116 preeclampsia women in the development and validation set, respectively. The model included 10 predictors: gestational age at admission, irregular prenatal care, number of symptoms, mean arterial pressure, hematocrit, platelet count, fibrinogen, albumin, total bilirubin, and serum urea. The area under the ROC curve of the model was 0.867 in the development set and 0.841 in the external validation set. The calibration plots for the probability of adverse outcomes demonstrated a good correlation. Decision curve analysis further showed that our model had clinical application value. The nomogram and a software-based calculator (https://sdfyyfck.shinyapps.io/preeclampsia/) were constructed for convenient clinical use. CONCLUSIONS Such a model could be used as a useful tool for the assessment of hypertensive-related complications in Chinese preeclampsia patients.

Abstract
Background Preeclampsia and eclampsia are common complications of pregnancy globally, including sub-Saharan African (SSA) countries. Although it has a high burden on maternal and neonatal mortality and morbidity, evidence on the risk of the problem is limited. Therefore, the aim of this review was to examine the factors associated with preeclampsia and eclampsia among mothers in SSA countries. Methods We searched article from SSA countries using electronic database MEDLINE, EMBASE, PubMed, CINAHL published in English from January 2000 to May 2020. Two reviewers independently screened, extracted and assessed the quality of the articles. Both random and fixed effect model were used for analysis. Heterogeneity of the studies and publication bias were checked. STATA 16 used for analysis. Results Fifty-one studies met the inclusion criteria and included in this review. The following factors were identified through meta-analysis: being primiparous (OR: 2.52; 95% CI:1.19, 3.86), previous history of maternal preeclampsia/eclampsia (OR:5.6; 95% CI:1.82, 9.28), family history of preeclampsia/eclampsia (OR:1.68; 95% CI:1.26, 2.11), high maternal body mass index (OR: 1.69; 95% CI:1.17, 2.21), chronic hypertension (OR: 2.52; 95% CI:1.29, 3.74), anaemia during pregnancy (OR: 3.22; 95% CI:2.70, 3.75) and lack of antenatal care visits (OR: 2.71; 95% CI:1.45, 3.96). There was inconclusive evidence for a relationship with a number of other factors, such as nutrition and related factors, antenatal care visits, birth spacing, and other factors due to few studies found in our review. Conclusions The risk of preeclampsia and eclampsia is worse among women who have a history of preeclampsia/eclampsia (either themselves or family members), primiparous, obesity and overweight, living with chronic disease, having anaemia during pregnancy and absence from ANC visits. Therefore, investment must be made in women’s health needs to reduce the problem and health service providers need to give due attention to high-risk women.

Early- and Late-Onset Preeclampsia: A Comprehensive Cohort Study of Laboratory and Clinical Findings according to the New ISHHP Criteria. Int J Hypertens 2019; 2019:4108271. [PMID: 31637053 PMCID: PMC6766116 DOI: 10.1155/2019/4108271] [Citation(s) in RCA: 58] [Impact Index Per Article: 11.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2018] [Revised: 07/05/2019] [Accepted: 08/21/2019] [Indexed: 12/22/2022] Open
Abstract
Recently, the diagnostic criteria of preeclampsia have been changed. No studies are available in the literature that analyzed in detail the differences between early-onset preeclampsia (EOP) and late-onset preeclampsia (LOP), taking into account the International Society for the Study of Hypertension in Pregnancy (ISSHP) criteria. Thus, we sought to retrospectively investigate in detail the differences in clinical and laboratory outcomes between EOP and LOP diagnosed according to the ISSHP criteria. A retrospective cohort study was conducted in 214 women with singleton pregnancies and preeclampsia admitted to the Department of Obstetrics and Perinatology of the University Hospital in Kraków, Poland, from 2013 to 2017 (113 (52.8%) women with EOP and 101 (47.2%) women with LOP). Electronic medical records were reviewed for demographics and medical history, laboratory tests, and delivery and neonatal data. Patients with preeclampsia accounted for 1.7% of the women who delivered during the study period. The EOP and LOP groups did not differ in the distribution of risk factors for preeclampsia. The most common risk factor was primiparity, which was observed in 72.0% of cases. Regarding the ISSHP diagnostic criteria, the two groups differed in the incidence of fetal growth restriction (p=0.0009), hemolysis (p=0.0416), and neurological complications (p=00342), which were found more often in the EOP group. In addition, the EOP group had more frequent occurrence of severe cardiorespiratory (p < 0.0001) and hematological (p=0.0127) complications, adverse fetoplacental conditions (p < 0.0001), and severe fetoplacental complications (p=0.0003). Children born to women with EOP had lower Apgar scores (p < 0.001) and higher rates of intraventricular hemorrhage (p < 0.0001), respiratory disorders requiring mechanical ventilation (p < 0.0001), and early (p=0.0004) and late sepsis (p=0.002). EOP differed from LOP in terms of maternal and perinatal adverse outcomes. The observed higher rates of fetoplacental adverse conditions and severe complications indicate a significant contribution of impaired placentation to the etiopathogenesis of EOP.
