Memon SI, Acharya NS. The Association Between Serum Homocysteine Levels and Placenta-Mediated Complications: A Narrative Review. Cureus 2022; 14:e31305.

Abstract
The most extremely unfavourable outcome of pregnancy is the death of the mother and newborn. Negative outcomes for mothers or babies can occur as a result of complications or issues during pregnancy, birth or the post-partum period. Early elevated maternal homocysteine (Hct) levels during pregnancy have been linked to altered placental development. There is evidence that suggests an elevated maternal blood Hct level is the new obstetrical risk factor, and the association between hyperhomocysteinemia (HHct) and numerous obstetrical problems was recently recognised. Hct is an essential amino acid, which contains sulphur and is formed from the metabolism of methionine. HHct has several known aetiologies, including genetic anomalies; a deficiency in folic acid, vitamin B6 and vitamin B12; hypothyroidism; old age; and renal illnesses. Vascular problems, coronary artery disease, atherosclerosis and embolic illnesses can all occur as a result of high blood levels of Hct. Hct levels are lower in normal pregnancies than it is in women who are not pregnant. Many pregnancy-related problems, including pre-eclampsia (PE), recurrent pregnancy loss (RPL), placental abruption, premature delivery and foetal growth restriction (FGR) have been connected to HHct in recent research. We looked for pertinent literature using a thorough and systematic search from PubMed, Medline, Embase, Cochrane Library, Google, etc., and articles that were published before August 2022 based on serum Hct levels and various placenta-mediated complications for this review. In this review, we described the synthesis and metabolism of Hct in humans, Hct levels at various phases of normal pregnancy and the association between Hct and placenta-mediated pregnancy complications. The outcomes discovered can help obstetricians increase the likelihood of a successful pregnancy in cases where placenta-mediated issues are present. Lowering Hct levels with a high dose of folic acid tablets during the subsequent pregnancy may be useful for women who experienced these difficulties in prior pregnancies as a result of HHct.

Bovee EM, Gulati M, Maas AH. Novel Cardiovascular Biomarkers Associated with Increased Cardiovascular Risk in Women With Prior Preeclampsia/HELLP Syndrome: A Narrative Review. Eur Cardiol 2021; 16:e36. [PMID: 34721670 PMCID: PMC8546910 DOI: 10.15420/ecr.2021.21] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2021] [Accepted: 08/11/2021] [Indexed: 12/11/2022] Open
Abstract
Evidence has shown that women with a history of preeclampsia or haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome have an increased risk of cardiovascular disease later in life. Recommendations for screening, prevention and management after such pregnancies are not yet defined. The identification of promising non-traditional cardiovascular biomarkers might be useful to predict which women are at greatest risk. Many studies are inconsistent and an overview of the most promising biomarkers is currently lacking. This narrative review provides an update of the current literature on circulating cardiovascular biomarkers that may be associated with an increased cardiovascular disease risk in women after previous preeclampsia/HELLP syndrome. Fifty-six studies on 53 biomarkers were included. From the summary of evidence, soluble fms-like tyrosine kinase-1, placental growth factor, interleukin (IL)-6, IL-6/IL-10 ratio, high-sensitivity cardiac troponin I, activin A, soluble human leukocyte antigen G, pregnancy-associated plasma protein A and norepinephrine show potential and are interesting candidate biomarkers to further explore. These biomarkers might be potentially eligible for cardiovascular risk stratification after preeclampsia/HELLP syndrome and may contribute to the development of adequate strategies for prevention of hypertension and adverse events in this population.

A Novel Review of Homocysteine and Pregnancy Complications. BIOMED RESEARCH INTERNATIONAL 2021; 2021:6652231. [PMID: 34036101 PMCID: PMC8121575 DOI: 10.1155/2021/6652231] [Citation(s) in RCA: 50] [Impact Index Per Article: 16.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/19/2020] [Accepted: 04/26/2021] [Indexed: 11/27/2022]
Abstract
Homocysteine (Hct) is a substance produced in the metabolism of methionine. It is an essential type of amino acid gained from the daily diet. Methylenetetrahydrofolate reductase (MTHFR) gene mutation is related to elevated total homocysteine (tHct) expressions, in particular, among women with low folate intake. Hyperhomocysteinemia (HHct) is caused by numerous factors, such as genetic defects, lack of folic acid, vitamin B6 and B12 deficiency, hypothyroidism, drugs, aging, and renal dysfunction. Increased Hct in peripheral blood may lead to vascular illnesses, coronary artery dysfunction, atherosclerotic changes, and embolic diseases. Compared to nonpregnant women, the Hct level is lower in normal pregnancies. Recent studies have reported that HHct was associated with numerous pregnancy complications, including recurrent pregnancy loss (RPL), preeclampsia (PE), preterm delivery, placental abruption, fetal growth restriction (FGR), and gestational diabetes mellitus (GDM). Besides, it was discovered that neonatal birth weight and maternal Hct levels were negatively correlated. However, a number of these findings lack consistency. In this review, we summarized the metabolic process of Hct in the human body, the levels of Hct in different stages of normal pregnancy reported in previous studies, and the relationship between Hct and pregnancy complications. The work done is helpful for obstetricians to improve the likelihood of a positive outcome during pregnancy complications. Reducing the Hct level with a high dosage of folic acid supplements during the next pregnancy could be helpful for females who have suffered pregnancy complications due to HHct.

Front Cardiovasc Med 2019; 6:160. [PMID: 31803757 PMCID: PMC6873287 DOI: 10.3389/fcvm.2019.00160] [Citation(s) in RCA: 35] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2019] [Accepted: 10/21/2019] [Indexed: 01/04/2023] Open
Abstract
Introduction: Hypertensive disorders (HDP) affect ~7% of pregnancies. Epidemiological evidence strongly suggests HDP independently increases that individual's risk of later cardiovascular disease (CVD). Focus on reduction or mitigation of this risk has been limited. This review seeks to identify trialed interventions to reduce cardiovascular risk after HDP. Methods: Online medical databases were searched to identify full-text published results of randomized controlled trials (RCT) in women <10 years postpartum after HDP that trialed interventions to reduce cardiovascular risk. Outcomes sought included cardiovascular disease events, chronic hypertension, and other measures of cardiovascular risk such as obesity, smoking status, diet, and physical activity. Publications from January 2008 to July 2019 were included. Results: Two RCTs were identified. One, a trial of calcium vs. placebo in 201 women with calcium commenced from the first follow-up visit outside of pregnancy and continued until 20 weeks' gestation if another pregnancy occurred. A non-significant trend toward decreased blood pressure was noted. The second RCT of 151 women tested an online education programme (vs. general information to control group) to increase awareness of risk factors and personalized phone-based lifestyle coaching in women who had a preeclampsia affected pregnancy in the 5 years preceding enrolment. Significant findings included increase in knowledge of CVD risk factors, reported healthy eating and decreased physical inactivity, however adoption of a promoted heart healthy diet and physical activity levels did not differ significantly between groups. Several observational studies after HDP, and one meta-analysis of studies of lifestyle interventions not performed specifically after HDP but used to extrapolate likely benefits of lifestyle interventions, were identified which supported the use of lifestyle interventions. Several ongoing RCTs were also noted. Discussion: There is a paucity of intervention trials in the early years after HDP to guide evidence-based cardiovascular risk reduction in affected women. Limited evidence suggests lifestyle intervention may be effective, however degree of any risk reduction remains uncertain. Conclusion: Sufficiently powered randomized controlled trials of appropriate interventions (e.g., lifestyle behavior change, pharmacological) are required to assess the best method of reducing the risk of cardiovascular disease in this at-risk population of women.

Abstract
Growing evidence has reported that a history of preeclampsia (PE) increases the risk of developing cardiovascular disease (CVD). Arterial stiffness plays a predictive role in CVD. Previous studies have demonstrated the close association between homocysteine (Hcy) level and arterial stiffness in community-based populations. This study was to assess whether Hcy level was independently associated with arterial stiffness in 168 women with a PE history who were analyzed at a 5-year follow-up. Brachial-ankle pulse wave velocity (baPWV) was measured by an automatic pulse-wave analyzer and a value >1,400 cm/s was defined as high arterial stiffness. Biochemical parameters were recorded and an Hcy value >10 μmol/L was defined as having hyperhomocysteine (H-Hcy). Variables that were significantly associated with baPWV were tested for independence by multivariate logistic regression analysis. We found that body mass index (OR 1.017, 95% CI 1.008-1.029), systolic blood pressure (OR 1.048, 95% CI 1.019-1.072), total cholesterol (OR 1.059, 95% CI 1.007-1.086), and Hcy level (OR 1.021, 95% CI 1.010-1.037) were independent determinants of baPWV in women with previous PE. Our findings indicate that Hcy pathway might be involved in arterial stiffness in women with a PE history. Whether Hcy would be a promising biomarker for serial stratified CVD risk management in these women deserves further evaluation on a large scale.

Abstract
Background and Objective: Evidence indicates that genetic factors may be involved in the risk of ischemic stroke (IS). The aim of this study was to assess the effect of genetic polymorphisms located in exons or untranslated regions of MTHFR as well as FV genes on ischemic stroke. Materials and Methods: In this case-control study, 106 patients with IS and 157 healthy volunteers (age <50 years) were genotyped for MTHFR C677T, A1298C, C2572A and C4869G, FVL, and prothrombin G20210A polymorphisms. Results: The MTHFR 677CT genotype was more frequent in patients and increased risk of IS with Odds Ratio = 1.9. The MTHFR A1298C and C2572A polymorphisms were not associated with IS in dominant and recessive models. Our findings showed a significant decrease in the MTHFR4869CG genotype in IS patients, and this variant was associated with a decreased risk of IS in the dominant model. The CAAT haplotype was associated with increased risk, and the GAAC haplotype was associated with decreased risk of IS compared to other haplotypes. There was no relation between FVL G1691A polymorphism and IS risk. Conclusions: The present study showed that the MTHFR 677CT genotype was more frequent and the MTHFR 4869CG genotype was less frequent in young IS patients.

Abstract
Although hyperhomocysteinemia (HHcy) is known to promote downstream pro-inflammatory cytokine elevation, the precise mechanism is still unknown. One of the possible receptors that could have significant attention in the field of hypertension is toll-like receptor 4 (TLR-4). TLR-4 is a cellular membrane protein that is ubiquitously expressed in all cell types of the vasculature. Its mutation can attenuate the effects of HHcy-mediated vascular inflammation and mitochondria- dependent cell death that suppresses hypertension. In this review, we observed that HHcy induces vascular remodeling through immunological adaptation, promoting inflammatory cytokine up-regulation (IL-1β, IL-6, TNF-α) and initiation of mitochondrial dysfunction leading to cell death and chronic vascular inflammation. The literature suggests that HHcy promotes TLR-4-driven chronic vascular inflammation and mitochondria-mediated cell death inducing peripheral vascular remodeling. In the previous studies, we have characterized the role of TLR-4 mutation in attenuating vascular remodeling in hyperhomocysteinemia. This review includes, but is not limited to, the physiological synergistic aspects of the downstream elevation of cytokines found within the vascular inflammatory cascade. These events subsequently induce mitochondrial dysfunction defined by excessive mitochondrial fission and mitochondrial apoptosis contributing to vascular remodeling followed by hypertension.

Abstract
BACKGROUND Hypertensive pregnancy disorders have been associated with subjective cognitive complaints or brain white-matter lesions 5 to 10 years after the hypertensive pregnancy. The long-term effects of hypertensive pregnancies on brain structure and cognitive function remain unknown. METHODS AND RESULTS This study included 1279 women who participated in the Family Blood Pressure Project Genetic Epidemiology Network of Arteriopathy (GENOA) study. As part of the ancillary Genetics of Microangiopathic Brain Injury (GMBI) study, a neurocognitive battery was administered; 1075 also had a brain magnetic resonance imaging. A history of a hypertensive pregnancy disorder was obtained by a self-report using a validated questionnaire. Linear models fit with generalized estimating equations were used to assess the association between hypertensive pregnancy disorders and cognition, adjusting for age, race, education, body mass index, smoking, current hypertension, hypertension duration, and family history of hypertension. Regression models for the brain magnetic resonance imaging outcomes also were adjusted for total intracranial volume. Women with histories of hypertensive pregnancy disorders performed worse on all measures of processing speed (Digital Symbol Substitution Test [mean score, 41.2 versus 43.4; P=0.005], Trail Making Test Part A [mean seconds, 45.1 versus 42.2; P=0.035], and Stroop [mean score, 173.9 versus 181.0; P=0.002]) and had smaller brain volumes compared with women with histories of normotensive pregnancies (286 versus 297; P=0.023). CONCLUSIONS Hypertensive pregnancy disorders are associated with worse performance on tests of processing speed and smaller brain volumes decades later. Population-based studies are needed to provide critical insight as to the contribution of hypertensive pregnancies to risk of cognitive decline and dementia.

A history of preeclampsia is associated with a risk for coronary artery calcification 3 decades later. Am J Obstet Gynecol 2016; 214:519.e1-519.e8. [PMID: 26874301 DOI: 10.1016/j.ajog.2016.02.003] [Citation(s) in RCA: 69] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2015] [Revised: 01/22/2016] [Accepted: 02/04/2016] [Indexed: 11/20/2022]
Abstract
BACKGROUND A history of preeclampsia is an independent risk factor for cardiac events and stroke. Changes in vasculature structure that contribute to these associations are not well understood. OBJECTIVE The aim of this study was to quantify coronary artery calcification (CAC), a known risk factor for cardiac events, in a prospective cohort of women with and without histories of preeclampsia. STUDY DESIGN Women without prior cardiovascular events (40 with and 40 without histories of preeclampsia, matched for parity and age at index birth) were recruited from a large population-based cohort of women who were residents of Olmsted County, Minnesota, and who delivered from 1976 through 1982. Computed tomography was performed to measure CAC in Agatston units. All pregnancy histories and covariates were confirmed by review of the medical records. Current clinical variables were assessed at the time of imaging. Differences between women with and without histories of preeclampsia were examined using χ(2) tests and tests; CAC, in particular, was compared as a categorical and ordinal variable, with a χ(2) test and with Wilcoxon 2-sample tests and ordinal logistic regression, as appropriate. RESULTS Mean age (SD) at imaging was 59.5 (±4.6) years. Systolic and diastolic blood pressures, hyperlipidemia, and current diabetes status did not differ between women with and without histories of preeclampsia. However, the frequencies of having a current clinical diagnosis of hypertension (60% vs 20%, P < .001) and higher body mass index in kg/m(2) (expressed as median [25th-75th percentile], 29.8 [25.9-33.7] vs 25.3 [23.1-32.0], P = .023) were both greater in the women with histories of preeclampsia compared to those without. The frequency of a CAC score >50 Agatston units was also greater in the preeclampsia group (23% vs 0%, P = .001). Compared to women without preeclampsia, the odds of having a higher CAC score was 3.54 (confidence interval [CI], 1.39-9.02) times greater in women with prior preeclampsia without adjustment, and 2.61 (CI, 0.95-7.14) times greater after adjustment for current hypertension. After adjustment for body mass index alone, the odds of having a higher CAC based on a history of preeclampsia remained significant at 3.20 (CI, 1.21-8.49). CONCLUSION In this first prospective cohort study with confirmation of preeclampsia by medical record review, a history of preeclampsia is associated with an increased risk of CAC >30 years after affected pregnancies, even after controlling individually for traditional risk factors. A history of preeclampsia should be considered in risk assessment when initiating primary prevention strategies to reduce cardiovascular disease in women. Among women with histories of preeclampsia, the presence of CAC may be able to identify those at a particularly high cardiovascular risk, and should be the subject of future studies.

Abstract
OBJECTIVE To investigate the change of level of serum homocysteine (Hcy), endothelin-1 (ET-1) and nitric oxide (NO) and clinical significance in patients with HDCP. METHODS Two hundred and thirty nine patients with HDCP (137 patients with mild preeclampsia, 102 patients with severe preeclampsia) who were hospitalized between June 2012 and June 2015 and 200 normal pregnancy women in outpatient department were enrolled in our study were divided into HDCP group and control group. Serum Hcy concentration was measured by enzymatic cycling assay. ET-1 concentration was measured by enzyme linked immunosorbent assay. And no concentration was measured by nitrate reductase assay. RESULTS Serum Hcy and ET-1 in HDCP group were significantly higher as compared to control group (P<0.05). Level of serum NO in HDCP group was significantly lower than in the control group (P<0.05). Level of serum Hcy and ET-1 in mild and severe preeclampsia group were significantly higher as compared to control group, respectively (P<0.05). Level of serum NO in mild and severe preeclampsia group were significantly lower than in the control group' respectively (P<0.05). Level of serum Hcy and ET-1 in severe preeclampsia group were significantly higher as compared to mild preclampsia group (P<0.05). Level of serum NO in severe preeclampsia group were significantly lower than in mild preeclampsia group (P<0.05). Spearman rank correlation analysis showed that level of serum Hcy and ET-1 was positively correlated with severity of diseases (r=0.689, 0.718, P<0.05). Level of serum NO was negatively correlated with severity of diseases (r=-0.702, P<0.05). CONCLUSION Serum Hcy, ET-1 and NO were associated with pathogenesis of HDCP. Comprehensively measurement of them could effectively evaluate the incidence and progress of HDCP.

Abstract
PURPOSE OF REVIEW Cardiovascular disease (CVD) remains the major killer of women around the globe. Complications during pregnancy, including hypertensive disorders of pregnancy and gestational diabetes mellitus, are now recognized as risk factors for future CVD. RECENT FINDINGS Studies of diverse populations demonstrate the links between these complications of pregnancy and a woman's future risk of CVD including atherosclerosis, hypertension, stroke, coronary artery disease, and heart failure. Markers that persist in these women following pregnancy continue to be identified and include microalbuminuria, proteinuria, elevated homocysteine levels, C-reactive protein, and salt sensitivity. Efforts are now being placed on establishing specialized clinics to monitor women beyond pregnancy to help reduce the burden of future disease. SUMMARY Pregnancy offers a unique window through which women at risk of future CVD may be identified. Clinicians have an opportunity to implement health monitoring, lifestyle modifications, and other interventions during this period, and beyond, that will help reduce the burden of CVD. Research should continue to focus on identifying and understanding the mechanisms that lead to future CVD in these women; deciphering whether pregnancy unmasks an existing predisposition to disease, compounds the risk of future disease, or is the direct cause of future disease.

Abstract
Over the last few decades, there has been increasing emphasis on cardiovascular disease in women and study of female-specific cardiovascular risk factors. Hypertension in pregnancy, and specifically preeclampsia, has been identified as one such risk factor. In this review, we explore the epidemiological evidence for preeclampsia as a risk factor for cardiovascular disease. We propose reasons for this association, giving evidence for potential pathways linking preeclampsia with future cardiovascular disease.
