Am J Obstet Gynecol MFM 2025; 7:101594. [PMID: 39755249 DOI: 10.1016/j.ajogmf.2024.101594] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2024] [Revised: 10/31/2024] [Accepted: 12/08/2024] [Indexed: 01/06/2025]
Abstract
BACKGROUND Chronic kidney disease is a significant cause of adverse obstetric outcomes. However, there are few studies assessing the risk of severe maternal morbidity and mortality among patients with chronic kidney disease and no studies assessing the association between individual indicators of severe maternal morbidity and chronic kidney disease. OBJECTIVE To evaluate the risk of severe maternal morbidity and mortality among pregnant patients with chronic kidney disease. STUDY DESIGN This was a population-based, retrospective cohort study including U.S. delivery hospitalizations from 2010-2020 utilizing the Healthcare Cost & Utilization Project National Inpatient Sample database. Patients were identified as having a delivery hospitalization, chronic kidney disease, and severe maternal morbidity using International Classification Diagnoses codes (9th and 10th edition). The primary outcomes were severe maternal morbidity and mortality, as defined according to the Centers for Disease Control and Prevention criteria. Multivariate logistic regression analyses were performed to estimate adjusted relative risk and 95% confidence intervals of severe maternal morbidity and mortality among patients with chronic kidney disease. Subgroup analyses were performed by chronic kidney disease etiology, stage, race and ethnicity, and individual indicators of severe maternal morbidity. RESULTS Among the 38,374,326 parturients in this study, 95,272 (0.2%) had chronic kidney disease. The risk of severe maternal morbidity was higher for those with chronic kidney disease (12.2% vs 0.7%, aRR 6.4, 95% CI 6.0-6.8) compared to those without. Among severe maternal morbidity indicators, those with chronic kidney disease were at highest risk for acute renal failure (aRR 21.7, 95% CI 19.8-23.7) and sepsis (aRR 9.0, 95% CI 7.6-10.5). Chronic kidney disease was also associated with an increased risk of maternal death (aRR 4.1, 95% CI 2.9-5.8). Black individuals had higher adjusted population attributable fraction (aPAF) between severe maternal morbidity and chronic kidney disease (aPAF 4.0%, 95% CI 3.6-4.3). Increased risk of severe maternal morbidity was associated with all chronic kidney disease subtypes, stages, and a history of renal transplant. Maternal death was significantly associated with diabetic nephropathy, renovascular, and obstructive or unspecified renal disease (aRR 7.3-14.1), as well as stages 3-5 of chronic kidney disease and a history of renal transplant (aRR 15.5-32.6). Risk of severe maternal morbidity and mortality were similar in those with a history of renal transplant and those with stage 1 chronic kidney disease. The number needed to treat with renal transplant to prevent 1 severe maternal morbidity event or maternal death in those with stages 3-5 chronic kidney disease was 2.6 (95% CI 2.4-2.9) and 45.0 (95% CI 31.0-82.0), respectively. CONCLUSION Chronic kidney disease in pregnancy was significantly associated with severe maternal morbidity, mortality, and other adverse perinatal outcomes, warranting close surveillance and multidisciplinary management throughout pregnancy.

Abstract
The growing incidence of obesity and the rising trend of increased age during pregnancy have led to a high number of pregnant women with chronic kidney disease (CKD). Chronic hypertension is commonly associated with CKD and is not only the result of renal damage but is also the cause of declining renal function. Pregnancy and its unique physiological adaptations are affected by a decrease in the filtration capacity of the kidneys. Preeclampsia is a disorder of the vascular endothelium and is exacerbated by endothelial dysfunction resulting from CKD. Blood pressure targets must be strictly maintained owing to overlapping disease pathogenesis and to minimize cardiovascular damage. Moreover, preexisting renal dysfunction poses a challenge in identifying superimposed preeclampsia, which alters the management strategies in pregnancy. Fetal outcomes in patients with CKD are considerably affected by the presence of hypertension. This review is expected to aid in developing a focused and individualized treatment plan for hypertension in pregnant women with CKD to improve pregnancy outcomes and preserve postpartum renal function.

Abstract
Chronic Kidney Disease (CKD) affects millions globally, with a notable impact on biological females of reproductive age. This population faces specific issues such as fertility concerns, complex contraceptive decisions, and complications related to pregnancy that can exacerbate CKD. Given the increasing prevalence of CKD among young men and women owing to rising rates of hypertension, obesity, and diabetes, there is a need for early and tailored interventions among women of childbearing age. Current Kidney Disease Improving Global Outcomes (KDIGO) guidelines suggest nephrology referral primarily for advanced CKD stages or significant proteinuria. However, women at any CKD stage may face complex pregnancy-related decisions and increased risks that are not adequately addressed by these guidelines, warranting early specialty care. This review explores the distinct needs of women of reproductive age with CKD, identifies gaps in the existing management framework, and advocates for earlier and more comprehensive nephrology involvement. By focusing on preconception planning, risk factor management, adverse pregnancy outcomes, and existing disparities in care, this review seeks to improve understanding of the needs of women of reproductive age with CKD and calls for a shift towards more proactive, nephrology-driven care.

Abstract
Hypertensive disease of pregnancy (HDP) is one of the most important causes of increased maternal mortality and perinatal complications during pregnancy. We investigated the pregnancy outcomes of 156 HDP patients (65 gestational hypertension [GH], 13 chronic hypertension [CH], 74 preeclampsia-eclampsia [PE-EC], and 4 superimposed on PE [CH with PE]). In patients with different types of HDP, levels of soluble fms like tyrosine kinase-1 (sFlt-1), placental growth factor (PlGF)-1, and prokinin-1 (PROK1) were measured and compared. The predictive efficacy of these indicators was evaluated using receiving operating characteristics curves and area under the curve. Results showed that the PE cohort had a higher sFlt-1/PlGF ratio (46.12 [39.24, 68.85]) and PROK1 (498.84 [213.67, 678.30] pg/mL) level than the GH (sFlt-1/PlGF, 32.3 [21.98, 58.00], PROK1 300.77[250.0, 345.29]pg/mL) and CH cohort (sFlt-1/PlGF, 37.49 [32.68, 39.68], PROK1, 281.48 [229.25, 453.94]pg/mL). In the HDP cohort, 54 patients experienced adverse pregnancy events, and the sFlt-1/PlGF ratio, PROK1, and the combined indicators (sFlt-1/PlGF ratio and PROK1) were excellent predictors of adverse pregnancy events, especially for PE patients.

Abstract
BACKGROUND Chronic kidney disease (CKD) is associated with an increased risk of adverse pregnancy outcomes, but the risk at different stages of CKD (defined by estimated glomerular filtration rate, eGFR) compared with women without CKD has not been quantified in large cohorts. OBJECTIVES To quantify the association between CKD and adverse pregnancy outcomes according to CKD definition, CKD stage and presence or absence of diabetes. SEARCH STRATEGY A systematic search of EMBASE and MEDLINE from inception to 5 January 2023. SELECTION CRITERIA English-language randomised controlled trials as well as cohort and case-control studies investigating adverse pregnancy outcomes in pregnant women with CKD. DATA COLLECTION AND ANALYSIS Two reviewers conducted independent data extractions. A random-effects model was used to estimate risk. MAIN RESULTS We included 19 studies with 3 251 902 women. Defining CKD using eGFR or serum creatinine produced results with greater effect size but wider confidence intervals. Compared with CKD stages 1-2, women with CKD stages 3-5 have a greater risk, but also greater imprecision in the risk estimate, of the following outcomes: pre-eclampsia (OR 55.18, 95% CI 2.63-1157.68, vs OR 24.74, 95% CI 1.75-348.70), preterm birth (OR 20.24, 95% CI 2.85-143.75, vs OR 8.18, 95% CI 1.54-43.46) and neonatal intensive care unit admission (OR 19.32, 95% CI 3.07-121.68, vs OR 9.77, 95% CI 2.49-38.39). Women with diabetic kidney disease, compared with women without diabetic kidney disease, have higher risks of maternal mortality, small-for-gestational-age neonates, pre-eclampsia and gestational hypertension. CONCLUSIONS There is heterogeneity in the definition of CKD in pregnancy. Future studies should consider ways to standardise its definition and measurement in pregnancy.

Abstract
A 37-year-old woman with chronic kidney disease (CKD) stage G4 with membranoproliferative glomerulonephritis was hospitalized for nephrotic syndrome and hypertension due to superimposed preeclampsia at 27 weeks into her third pregnancy. Proteinuria did not worsen significantly after pulse steroid therapy. Delivery was induced at 30 weeks' gestation due to the maternal renal function and fetal growth. No obvious fetal complications other than preterm delivery were observed. In this case, we successfully managed a high-risk patient with membranoproliferative glomerulonephritis complicated by advanced CKD, nephrotic syndrome, and hypertension, which are independent risk factors for pregnancy complications.

Abstract
BACKGROUND Pre-existing health conditions increase the risk of obstetric complications during pregnancy and birth. However, the prevalence and recent changes in the frequency of pre-existing health conditions in the childbearing population remain unknown. OBJECTIVES To estimate the temporal changes in the prevalence of pre-existing health conditions among pregnant women in British Columbia, Canada. METHODS We carried out a population-based cross-sectional study of 825,203 deliveries in BC between 2000 and 2019 and examined 17 categories of physical and psychiatric health conditions recorded within 5 years before childbirth. We also undertook age-period-cohort analyses to evaluate temporal changes in pre-existing health conditions. RESULTS The prevalence of any pre-existing health condition was 26.2% (n = 216,214) with overall trends remaining stable during the study period. Between 2000 and 2019, the prevalence rates of anxiety (5.6%-9.6%), bipolar (1.6%-3.4%), psychosis (0.7%-0.8%), and eating disorders (0.2%-0.3%) increased. The prevalence of hypertension increased sharply from 0.06% in 2000 to 0.3% in 2019. Diabetes mellitus and stroke rates increased, as did the prevalence of systemic lupus, multiple sclerosis, and chronic kidney disease. Advanced maternal age was strongly associated with both psychiatric and circulatory/metabolic conditions. A strong birth cohort effect was evident, with rates of psychiatric conditions increasing among women born after 1985. CONCLUSIONS In British Columbia, Canada, 1 in 4 mothers had a pre-existing health condition 5 years prior to pregnancy. These findings underscore the need for multi-disciplinary care for women with pre-existing health conditions to improve maternal, foetal, and infant health.

Hypertens Res 2024; 47:1842-1851.

Abstract
Limited research exists on identifying risk factors for preeclampsia (PE) in the chronic kidney disease (CKD) population, especially across different patient sources. This study aimed to address this gap by analyzing clinical data from CKD pregnant women admitted to Peking University Third Hospital from January 2012 to December 2022. Logistic regression analysis identified independent risk factors for PE in the CKD population and assessed variations among patients from different sources. Additionally, a predictive model for PE was established using data from the registered group. The study included 524 CKD patients. Hypertension, proteinuria, fibrinogen >4 g/L, serum albumin ≤30 g/L, and uric acid >260 μmol/L were independent risk factors for PE in the overall CKD population. Subgroup analysis revealed that hypertension, serum albumin ≤30 g/L, and uric acid >260 μmol/L were independent risk factors in the referred group, while hypertension, uric acid >260 μmol/L, and fibrinogen >4 g/L were independent risk factors in the registered group. The prediction model based on registered group risk factors showed good predictive efficiency, with the area under the curve of 0.774 in the training set and 0.714 in the validation set. In conclusion, this study revealed that hypertension and elevated uric acid are independent risk factors for PE in CKD patients regardless of patient source, while serum albumin and fibrinogen levels are associated with PE risk in specific patient subgroups. Our predictive model enables clinicians to quickly identify the risk of PE in CKD patients, and early intervention treatment to improve pregnancy outcomes.

Abstract
Individualized pre-pregnancy counseling and antenatal care for women with chronic kidney disease (CKD) require disease-specific data. Here, we investigated pregnancy outcomes and long-term kidney function in women with COL4A3-5 related disease (Alport Syndrome, (AS)) in a large multicenter cohort. The ALPART-network (mAternaL and fetal PregnAncy outcomes of women with AlpoRT syndrome), an international collaboration of 17 centers, retrospectively investigated COL4A3-5 related disease pregnancies after the 20th week. Outcomes were stratified per inheritance pattern (X-Linked AS (XLAS)), Autosomal Dominant AS (ADAS), or Autosomal Recessive AS (ARAS)). The influence of pregnancy on estimated glomerular filtration rate (eGFR)-slope was assessed in 192 pregnancies encompassing 116 women (121 with XLAS, 47 with ADAS, and 12 with ARAS). Median eGFR pre-pregnancy was over 90ml/min/1.73m2. Neonatal outcomes were favorable: 100% live births, median gestational age 39.0 weeks and mean birth weight 3135 grams. Gestational hypertension occurred during 23% of pregnancies (reference: 'general' CKD G1-G2 pregnancies incidence is 4-20%) and preeclampsia in 20%. The mean eGFR declined after pregnancy but remained within normal range (over 90ml/min/1.73m2). Pregnancy did not significantly affect eGFR-slope (pre-pregnancy β=-1.030, post-pregnancy β=-1.349). ARAS-pregnancies demonstrated less favorable outcomes (early preterm birth incidence 3/11 (27%)). ARAS was a significant independent predictor for lower birth weight and shorter duration of pregnancy, next to the classic predictors (pre-pregnancy kidney function, proteinuria, and chronic hypertension) though missing proteinuria values and the small ARAS-sample hindered analysis. This is the largest study to date on AS and pregnancy with reassuring results for mild AS, though inheritance patterns could be considered in counseling next to classic risk factors. Thus, our findings support personalized reproductive care and highlight the importance of investigating kidney disease-specific pregnancy outcomes.

Bestman PL, Kolleh EM, Moeng E, Brhane T, Nget M, Luo J. Association between multimorbidity of pregnancy and adverse birth outcomes: A systemic review and meta-analysis. Prev Med 2024; 180:107872. [PMID: 38272269 DOI: 10.1016/j.ypmed.2024.107872] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/18/2023] [Revised: 12/18/2023] [Accepted: 01/18/2024] [Indexed: 01/27/2024]
Abstract
Multimorbidity (≥2 co-existing conditions) in pregnancy is a significant public health issue with a rising prevalence worldwide. However, the association between pregnancy multimorbidity and adverse birth outcomes is unclear. So, this review assessed the association between pregnancy-multimorbidity and adverse birth outcomes (preterm birth, abnormal birth weight, neonatal mortality, and stillbirth). Relevant peer-reviewed papers in PubMed, Web of Science, Elsevier/ScienceDirect, and Google Scholar were systematically search from January 1990 to March 2023. We used the random-effects model to calculate the multimorbidity pooled odds ratio, quantified heterogeneity using I2 statistics, and performed subgroup and sensitivity analyses in Stata version 17. The review protocol is registered with PROSPERO (CRD42023421336). The meta-analysis included 21 observational studies involving 6,523,741 pregnant women. The overall pooled odds of pregnancy multimorbidity associated with adverse birth outcomes were 3.11(2.14-4.09), 3.76(2.56-4.96) in Europe, 3.38(1.18-5.58) in North America, and 2.94(0.78-5.09) in Asia. Pregnant women with psychological and physical multimorbidity had increased odds of 5.65(1.71-9.59) and 2.75(1.71-9.58), respectively, for adverse birth outcomes. Pregnancy multimorbidity was associated with preterm birth 4.28(2.23-6.34), large gestational age (>90 percentile) 3.33(1.50-5.17), macrosomia (≥4000 g) 2.16(0.34-3.98), and small gestational age (<10th percentile) 3.52(1.54-5.51). There is substantial variance in the odds of pregnancy multimorbidity by type of comorbidity and type of adverse birth outcome, attributed to differences in the healthcare system by geographical location. Therefore, prioritizing pregnant women with multimorbidity is crucial for effective and integrative interventions.

Abstract
Hypertension is the leading cause of cardiovascular disease in women, and sub-Saharan African (SSA) countries have some of the highest rates of hypertension in the world. Expanding knowledge of causes, management, and awareness of hypertension and its co-morbidities worldwide is an effective strategy to mitigate its harms, decrease morbidities and mortality, and improve individual quality of life. Hypertensive disorders of pregnancy (HDPs) are a particularly important subset of hypertension, as pregnancy is a major stress test of the cardiovascular system and can be the first instance in which cardiovascular disease is clinically apparent. In SSA, women experience a higher incidence of HDP compared with other African regions. However, the region has yet to adopt treatment and preventative strategies for HDP. This delay stems from insufficient awareness, lack of clinical screening for hypertension, and lack of prevention programs. In this brief literature review, we will address the long-term consequences of hypertension and HDP in women. We evaluate the effects of uncontrolled hypertension in SSA by including research on heart disease, stroke, kidney disease, peripheral arterial disease, and HDP. Limitations exist in the number of studies from SSA; therefore, we will use data from countries across the globe, comparing and contrasting approaches in similar and dissimilar populations. Our review highlights an urgent need to prioritize public health, clinical, and bench research to discover cost-effective preventative and treatment strategies that will improve the lives of women living with hypertension in SSA.

Abstract
BACKGROUND The prevalence of chronic hypertension in women of reproductive age is on the rise mainly due to delayed childbearing. Maternal chronic hypertension, prevailing prior to conception or manifesting within the early gestational period, poses a substantial risk for the development of preeclampsia with adverse maternal and fetal outcomes, specifically as a result of placental dysfunction. We aimed to investigate whether chronic hypertension is associated with placenta-mediated complications regardless of the development of preeclampsia in pregnancy. METHODS This was a population-based, retrospective cohort study from 'Soroka' university medical center (SUMC) in Israel, of women who gave birth between 1991 and 2021, comparing placenta-mediated complications (including fetal growth restriction (FGR), placental abruption, preterm delivery, and perinatal mortality) in women with and without chronic hypertension. Generalized estimating equation (GEE) models were used for each outcome to control for possible confounding factors. RESULTS A total of 356,356 deliveries met the study's inclusion criteria. Of them, 3949 (1.1%) deliveries were of mothers with chronic hypertension. Women with chronic hypertension had significantly higher rates of all placenta-mediated complications investigated in this study. The GEE models adjusting for preeclampsia and other confounding factors affirmed that chronic hypertension is independently associated with all the studied placental complications except placental abruption. CONCLUSIONS Chronic hypertension in pregnancy is associated with placenta-mediated complications, regardless of preeclampsia. Therefore, early diagnosis of chronic hypertension is warranted in order to provide adequate pregnancy follow-up and close monitoring for placental complications, especially in an era of advanced maternal age.

Abstract
BACKGROUND Hypertensive disorders during pregnancy continue to increase in prevalence and are associated with several adverse outcomes and future cardiovascular risk for mothers. This study evaluated the association of hypertensive disorders compared to no hypertension during pregnancy with neonatal and maternal outcomes. We then evaluated risk factors associated with progression from a less to more severe hypertensive disorder during pregnancy. METHODS We conducted a propensity-matched retrospective cohort study utilizing Medicaid claims data from a national insurer. The study population consisted of mothers with and without hypertensive disorders who delivered between 7/1/2016-12/31/2018 and their infants. Hypertensive disorders included gestational hypertension, chronic hypertension, preeclampsia, and superimposed preeclampsia. Propensity score matching was used to match mothers without to those with hypertensive disorders. Regression models were used to compare maternal and neonatal outcomes. Stepwise logistic regression was used to determine characteristics associated with the progression of gestational hypertension to preeclampsia or chronic hypertension to superimposed preeclampsia. RESULTS We observed the highest risk of cesarean delivery (odds ratio [OR]:1.61 and 1.99) in mothers and preterm delivery (OR:2.22 and 5.37), respiratory distress syndrome (OR:2.39 and 4.19), and low birthweight (OR:3.64 and 9.61) in babies born to mothers with preeclampsia or superimposed preeclampsia compared to no hypertension, respectively (p < 0.05 for all outcomes). These outcomes were slightly higher among chronic or gestational hypertension compared to no hypertension, however, most were not statistically significant. Risk of neonatal intensive care unit utilization was higher among more severe hypertensive disorders (OR:2.41 for preeclampsia, OR:4.87 for superimposed preeclampsia). Obesity/overweight and having a history of preeclampsia during a prior pregnancy were most likely to predict progression from gestational/chronic hypertension to preeclampsia/superimposed preeclampsia. CONCLUSION Mothers and neonates born to mothers with preeclampsia or superimposed preeclampsia experienced more adverse outcomes compared to those without hypertension. Mothers and neonates born to mothers with gestational hypertension had outcomes similar to those without hypertension. Outcomes for those with chronic hypertension fell in between gestational hypertension and preeclampsia. Obesity/overweight and having a history of preeclampsia during a prior pregnancy were strong risk factors for hypertension progression.

Abstract
Background Previous studies have identified a series of specific adverse pregnancy outcomes (APOs) linked with temperature extremes. Most of them focus on preterm birth, low birth weight, and stillbirth. Other possible adverse outcomes were under-researched. This study aimed to investigate the impact of ambient temperature on maternal complications, white blood cell count (WBC), newborn hearing, and neonatal jaundice. Methods A total of 418 participants were recruited from Fuzhou Maternity & Child Healthcare Hospital in 2016. Participants were invited to fill out a structured questionnaire. The gridded near-surface air temperatures at a resolution of 0.1°* 0.1° for Fuzhou were extracted from a published dataset. Meteorological data and PM2.5 were extracted based on participants' residential addresses using R packages "ncdf4" and "raster." Multivariate logistic regression models were used to quantify the effects of ambient temperature on APOs after controlling for confounders. Results Overall, there were 107 APOs, accounting for 25.6% of all participants. Every 1°C increase in mean temperature was associated with a 10.0% increase in APOs (aOR = 1.100, 95%CI 1.006-1.203) during the period of early pregnancy. However, negative associations were observed in the middle pregnancy period, and a 1°C increase in mean temperature was associated 8.8% decrease in APOs (aOR = 0.912, 95%CI 0.846-0.982). Diurnal temperature variation had a significant impact on APOs in the third trimester. Infant jaundice was negatively associated with temperature exposure in the middle and late pregnancy periods. The risk of neonatal jaundice increased at lag weeks 2-9 in the first trimester, with the greatest lagged effect (aOR = 1.201, 95%CI 1.020-1.413) observed at lag week 3. A 1°C increase in mean temperature led to a 29.6% (aOR = 1.296, 95%CI 1.019-1.649) increase in high WBC. A 1°C increase in temperature variation was associated with more than two times (aOR = 2.469, 95%CI 1.001-6.089) increase of high WBC in the first trimester and about five times (aOR = 4.724, 95%CI 1.548-14.409) increase in the third trimester. Conclusion Ambient temperature affects neonatal jaundice, newborn hearing loss, and infections during pregnancy. In addition to the identified epidemiologic link and susceptible exposure windows, there is a need to understand the underlying biological mechanisms for better recommendations for climate change adaptation policies.

Abstract
INTRODUCTION Women with Chronic Kidney Disease (CKD) are at increased risk of adverse pregnancy and renal outcomes. It is unknown how women with CKD understand their pregnancy risk. This nine-centre, cross-sectional study aimed to explore how women with CKD perceive their pregnancy risk and its impact on pregnancy intention, and identify associations between biopsychosocial factors and perception of pregnancy risk and intention. METHODS Women with CKD in the UK completed an online survey measuring their pregnancy preferences; perceived CKD severity; perception of pregnancy risk; pregnancy intention; distress; social support; illness perceptions and quality of life. Clinical data were extracted from local databases. Multivariable regression analyses were performed. Trial registration: NCT04370769. RESULTS Three hundred fifteen women participated, with a median estimated glomerular filtration rate (eGFR) of 64 ml/min/1.73m2 (IQR 56). Pregnancy was important or very important in 234 (74%) women. Only 108 (34%) had attended pre-pregnancy counselling. After adjustment, there was no association between clinical characteristics and women's perceived pregnancy risk nor pregnancy intention. Women's perceived severity of their CKD and attending pre-pregnancy counselling were independent predictors of perceived pregnancy risk. Importance of pregnancy was an independent predictor of pregnancy intention but there was no correlation between perceived pregnancy risk and pregnancy intention (r = - 0.002, 95% CI - 0.12 to 0.11). DISCUSSION Known clinical predictors of pregnancy risk for women with CKD were not associated with women's perceived pregnancy risk nor pregnancy intention. Importance of pregnancy in women with CKD is high, and influences pregnancy intention, whereas perception of pregnancy risk does not.

Abstract
OBJECTIVES Multimorbidity is defined as the coexistence of two or more chronic physical or psychological conditions within an individual. The association between maternal multimorbidity and adverse perinatal outcomes such as preterm delivery and low birth weight has not been well studied. Therefore, this study aimed to investigate this association. METHODS We conducted a prospective cohort study using data from the Japan Environment and Children's Study of pregnant women between 2011 and 2014. Those with data on chronic maternal conditions were included in the study and categorised as having no chronic condition, one chronic condition or multimorbidities. The primary outcomes were the incidence of preterm birth (PTB), low birth weight (LBW) and small for gestational age (SGA). Adjusted logistic regression was performed to estimate ORs (aORs) and 95% CIs. RESULTS Of the 104 062 fetal records, 86 885 singleton pregnant women were analysed. The median maternal age and body mass index were 31 years and 20.5 kg/m2, respectively. The prevalence of pregnant women with one or more chronic conditions was 40.2%. The prevalence of maternal multimorbidity was 6.3%, and that of PTB, LBW, and SGA were 4.6%, 8.1%, and 7.5%, respectively. Pre-pregnancy underweight women were the most common, observed in 15.6% of multimorbidity cases, followed by domestic violence from intimate partner in 13.0%. Maternal multimorbidity was significantly associated with PTB (aOR 1.50; 95% CI 1.33-1.69), LBW (aOR 1.49; 95% CI 1.35-1.63) and SGA (aOR 1.33; 95% CI 1.20-1.46). CONCLUSION Maternal multimorbidity was associated with adverse perinatal outcomes, including PTB, LBW and SGA. The risk of adverse perinatal outcomes tends to increase with a rise in the number of chronic maternal conditions. Multimorbidity becomes more prevalent among pregnant women, making our findings important for preconception counselling.

Abstract
Background It has been suggested that chronic hypertension is a risk factor for negative maternal and fetal outcomes during pregnancy and postpartum. We aimed to estimate the association of chronic hypertension on adverse maternal and infant outcomes and assess the impact of antihypertensive treatment and these outcomes. Methods and Results Using data from the French national health data system, we identified and included in the CONCEPTION cohort all women in France who delivered their first child between 2010 and 2018. Chronic hypertension before pregnancy was identified through antihypertensive medication purchases and by diagnosis during hospitalization. We assessed the incidence risk ratios (IRRs) of maternofetal outcomes using Poisson models. A total of 2 822 616 women were included, and 42 349 (1.5%) had chronic hypertension and 22 816 were treated during pregnancy. In Poisson models, the adjusted IRR (95% CI) of maternofetal outcomes for women with hypertension were as follows: 1.76 (1.54-2.01) for infant death, 1.73 (1.60-1.87) for small gestational age, 2.14 (1.89-2.43) for preterm birth, 4.58 (4.41-4.75) for preeclampsia, 1.33 (1.27-1.39) for cesarean delivery, 1.84 (1.47-2.31) for venous thromboembolism, 2.62 (1.71-4.01) for stroke or acute coronary syndrome, and 3.54 (2.11-5.93) for maternal death postpartum. In women with chronic hypertension, being treated with an antihypertensive drug during pregnancy was associated with a significantly lower risk of obstetric hemorrhage, stroke, and acute coronary syndrome during pregnancy and postpartum. Conclusions Chronic hypertension is a major risk factor of infant and maternal negative outcomes. In women with chronic hypertension, the risk of pregnancy and postpartum cardiovascular events may be decreased by antihypertensive treatment during pregnancy.

Abstract
About 3% of pregnant women suffer from chronic kidney disease (CKD). This article reviews the literature on the outcomes of neonates born to mothers with CKD (including those undergoing dialysis and kidney transplantation), and the results show that CKD during pregnancy may increase the risk of preterm birth, low birth weight, and small for gestational age infant, but it does not increase the risk of congenital anomalies. As for long-term outcomes, CKD during pregnancy has no significant impact on offspring's physical development and immune function. Neurodevelopmental outcome of offspring is associated with preterm birth and low birth weight, rather than intrauterine drug exposure. However, further research and follow-up are needed to investigate the outcome of neonates born to mothers with CKD.

Abstract
BACKGROUND Chronic hypertension (CH) adversely impacts pregnancy. It remains unclear whether antihypertensive treatment alters these risks. We examined the role of antihypertensive treatment in the association between CH and adverse pregnancy outcomes. METHODS Electronic health records from the UK Caliber and Clinical Practice Research Datalink were used to define a cohort of women delivering between 1997 and 2016. Primary outcomes were preeclampsia, preterm birth (PTB), and fetal growth restriction (FGR). We used multivariable logistic regression to compare outcomes in women with CH to women without CH and propensity score matching to compare antihypertensive agents. RESULTS The study cohort consisted of 1 304 679 women and 1 894 184 births. 14 595 (0.77%) had CH, and 6786 (0.36%) were prescribed antihypertensive medications in pregnancy. Overall, women with CH (versus no CH), had higher odds of preeclampsia (adjusted odds ratio [aOR], 5.74 [95% CI, 5.44-6.07]); PTB (aOR, 2.53 [2.39-2.67]); and FGR (aOR, 2.51 [2.31-2.72]). Women with CH prescribed treatment (versus untreated women) had higher odds of preeclampsia (aOR, 1.17 [1.05-1.30]), PTB (1.25 [1.12-1.39]), and FGR (1.80 [1.51-2.14]). Women prescribed methyldopa (versus β-blockers) had higher odds of preeclampsia (aOR, 1.43 [1.19-1.73]); PTB (1.59 [1.30-1.93]), but lower odds of FGR (aOR, 0.66 [0.48-0.90]). Odds of adverse outcomes were similar in relation to calcium channel blockers (versus β-blockers) except for PTB (aOR, 1.94 [1.15-3.27]). Among women prescribed treatment, lower average blood pressure (<135/85 mm Hg) was associated with better pregnancy outcomes. CONCLUSIONS Treatment with antihypertensive agents and control of hypertension ameliorates some effects but higher risks of adverse outcomes persist. β-Blockers versus methyldopa may be associated with better pregnancy outcomes except for FGR. Powered trials are needed to inform optimal treatment of CH during pregnancy.

Abstract
Pregnancy-induced hypertension syndrome (PIH) is a common pregnancy syndrome that could cause varying degrees of maternal and fetal organic damage and even endanger their lives. This study aimed to investigate ultrasound of fetal cardiac function changes in PIH. Totally 40 cases of gestational hypertension admitted to Cangzhou Central Hospital between October 2018 and September 2019 were enrolled in the hypertension group, and 40 women with healthy pregnancies during the same period were assigned to the normal group. Ultrasound results showed that PIH was associated with a significantly higher fetal cardiac septal thickness, fetal left ventricular end-diastolic area and end-systolic area, fetal right ventricular end-diastolic area and end-systolic area, fetal left ventricular systolic fraction 1 (VSF1), fetal left ventricular systolic fraction 2 (VSF2), fetal right VSF1, and fetal right VSF2 versus healthy pregnancy. The PIH fetuses had significantly lower neonatal weights versus healthy fetuses. Newborns of hypertensive pregnancies have larger hearts, faster heart rates, increased cardiac contractility, and lower weights versus newborns of healthy pregnancies.

Abstract
OBJECTIVE Limited evidence exists on the role that the cause of chronic kidney disease plays in determining pregnancy outcomes. The aim of this systematic review and meta-analysis was to examine the association between chronic kidney disease and adverse pregnancy outcomes by the cause and severity of chronic kidney disease where reported. The protocol was registered under the International Prospective Register of Systematic Reviews (CRD42020211925). DATA SOURCES PubMed, Embase, and Web of Science were searched until May 24, 2021, supplemented with reference list checking. STUDY ELIGIBILITY CRITERIA Studies that compared the pregnancy outcomes in women with or without chronic kidney disease were included. Two reviewers independently screened titles, abstracts, and full-text articles according to a priori defined inclusion criteria. METHODS Data extraction and quality appraisal were performed independently by 3 reviewers. The grading of recommendations, assessment, development, and evaluation approach was used to assess the overall certainty of the evidence. Random-effects meta-analyses were used to calculate the pooled estimates using the generic inverse variance method. The primary outcomes included preeclampsia, cesarean delivery, preterm birth (<37 weeks' gestation), and small for gestational age babies. RESULTS Of 4076 citations, 31 studies were included. Prepregnancy chronic kidney disease was significantly associated with a higher odds of preeclampsia (pooled crude odds ratio, 8.13; [95% confidence interval, 4.41-15], and adjusted odds ratio, 2.58; [1.33-5.01]), cesarean delivery (adjusted odds ratio, 1.65; [1.21-2.25]), preterm birth (adjusted odds ratio, 1.73; [1.31-2.27]), and small for gestational age babies (adjusted odds ratio, 1.93; [1.06-3.52]). The association with stillbirth was not statistically significant (adjusted odds ratio, 1.67; [0.96-2.92]). Subgroup analyses indicated that different causes of chronic kidney disease might confer different risks and that the severity of chronic kidney disease is associated with a risk of adverse pregnancy outcomes, as pregnancies with later stages of chronic kidney disease had higher odds of preeclampsia, preterm birth, and small for gestational age babies than those at earlier stages. The grading of recommendations, assessment, development, and evaluation certainty of the evidence overall was "very low". CONCLUSION This meta-analysis quantified the associations between prepregnancy chronic kidney disease and adverse pregnancy outcomes, both overall and according to the cause and severity of the disease. These findings might support the clinicians aiming to counsel women having chronic kidney disease by allowing them to tailor their advice according to cause and severity of the chronic kidney disease. We identified the gaps in the literature, and further studies examining the effect of specific kidney diseases and other clinical characteristics (eg, proteinuria, hypertension) on adverse pregnancy outcomes are warranted.

Abstract
Preterm labor (before 37 weeks' gestation) is the leading cause of neonatal mortality and morbidity, which can be divided into iatrogenic preterm labor, infectious preterm labor, and spontaneous preterm labor (sPTL). Up to now, there continue to be great difficulties in prediction and prevention of sPTL, owing to multiple risk factors, pathogenesis, and pathologic processes contributing to the event, which have not been fully clarified. Pregnancy maintenance and parturition is a complicated process with continuous maternal-fetal dialogue, in which both maternal and fetal factors participate and affect the outcome of pregnancy, including sPTL. Besides, external factors can also participate in sPTL, individually or through the interaction with internal factors. In this article, we summarize recent studies regarding sPTL from our and other groups, and discuss the risk factors and pathogenesis of preterm birth from both external and internal (maternal and fetal) aspects, so as to provide theoretical evidences for the diagnosis, prevention, and treatment of sPTL in the future.

Effect of Oral Prophylactic Measures on the Occurrence of Pre-Eclampsia (OP-PE) in High-Risk Pregnant Women: A Cluster Randomized Controlled Trial. Methods Protoc 2021; 4:mps4030061. [PMID: 34564307 PMCID: PMC8482225 DOI: 10.3390/mps4030061] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2021] [Revised: 08/25/2021] [Accepted: 09/02/2021] [Indexed: 11/16/2022] Open
Abstract
Pre-eclampsia (PE), a pregnancy-specific hypertensive disorder, characterized by the development of placental endothelial dysfunction, remains a major source of maternal and perinatal morbidity and mortality, especially in low- and middle-income settings. Periodontal disorders during pregnancy, and particularly periodontal pathogens, may be related to the risk of PE. Standard oral hygiene methods, based mainly on the joint use of toothbrushes and interdental brushes, reduce periodontal inflammatory risk and modulate the dysbiosis of the oral microbiome. The aim of this trial is to compare the PE outcomes in high-risk pregnant women receiving oral prophylactic measures to a control group. This trial is designed as a two-arm, parallel, cluster randomized controlled trial with the antenatal obstetric clinic as the unit of randomization and an allocation ratio of 1:1. The pregnant women will be included at 3 months of pregnancy and will be followed throughout the pregnancy. The primary outcome measure will be the incidence of PE from a baseline during the pregnancy. Secondary outcomes measures will include changes from the baseline in quantification of the pathogenic bacterial load of the interdental microbiota, the severity scores of periodontal indicators, and the incidence of adverse perinatal outcomes. This trial should demonstrate that the implementation of daily oral hygiene reduces oral dysbiosis, the incidence of periodontal disease, and the risk of PE.
