Metabolic syndrome in normal and complicated pregnancies

Effects of dietary fiber on maternal health in pregnant women with metabolic syndrome risk: a randomized controlled trial

Metabolic Syndrome (MetS) during pregnancy can lead to complications such as gestational diabetes mellitus (GDM) and hypertensive disorders. In this study, we sought to examine the influence of dietary fiber, from both food sources and soluble fiber supplementation, on the metabolic health and overall pregnancy outcomes of women at high risk of MetS. We conducted a randomized controlled trial involving 376 women between 11 and 13 weeks of gestation. To evaluate dietary fiber intake, we performed an exhaustive dietary component analysis using a food frequency questionnaire. Additionally, the participants in the intervention group received daily soluble fiber supplements until delivery. All participants underwent nutritional consultations and metabolic health assessments at three distinct stages of pregnancy (GW 11-13, GW 24-26, and GW 32-34). Our findings revealed a significant correlation between insufficient dietary fiber intake and an increased risk of GDM, even after adjusting for variables such as maternal age and pre-pregnancy BMI. We also noted that a high total dietary fiber intake was associated with reduced changes in triglyceride levels. In addition, the intervention group showed lower need for constipation medication, and soluble fiber supplementation may offer potential benefits for GDM patients. Importantly, our study verified the safety of long-term soluble fiber supplementation during pregnancy. Our results underscore the importance of adequate fiber intake, particularly from dietary sources, for the metabolic health of pregnant women. Moreover, our findings suggest that early fiber supplementation may benefit pregnant women experiencing constipation or those diagnosed with GDM.

Early pregnancy metabolic syndrome and risk for adverse pregnancy outcomes: findings from Rajarata Pregnancy Cohort (RaPCo) in Sri Lanka

BACKGROUND

Despite the intergenerational effects of metabolic disorders, evidence is greatly lacking on early pregnancy metabolic syndrome (MetS) and its effects on pregnancy outcomes from low- and middle-income countries. Thus, this prospective cohort of South Asian pregnant women aimed to evaluate how early pregnancy MetS would affect pregnancy outcomes.

METHODS

A prospective cohort study was conducted among first-trimester (T1) pregnant women of Anuradhapura district, Sri Lanka recruited to the Rajarata Pregnancy Cohort in 2019. MetS was diagnosed by the Joint Interim Statement criteria before 13 weeks of gestational age (GA). Participants were followed up until their delivery, and the major outcomes measured were large for gestational age (LGA), small for gestational age (SGA), preterm birth (PTB) and miscarriage (MC). Gestational weight gain, gestational age at delivery and neonatal birth weight were used as measurements to define the outcomes. Additionally, outcome measures were re-assessed with adjusting fasting plasma glucose (FPG) thresholds of MetS to be compatible with hyperglycemia in pregnancy (Revised MetS).

RESULTS

2326 T1 pregnant women with a mean age of 28.1 years (SD-5.4), and a median GA of 8.0 weeks (IQR-2) were included. Baseline MetS prevalence was 5.9% (n = 137, 95%CI-5.0-6.9). Only 2027 (87.1%) women from baseline, had a live singleton birth, while 221(9.5%) had MC and 14(0.6%) had other pregnancy losses. Additionally, 64(2.8%) were lost to follow-up. A higher cumulative incidence of LGA, PTB, and MC was noted among the T1-MetS women. T1-MetS carried significant risk (RR-2.59, 95%CI-1.65-3.93) for LGA, but reduced the risk for SGA (RR-0.41, 95%CI-0.29-0.78). Revised MetS moderately increased the risk for PTB (RR-1.54, 95%CI-1.04-2.21). T1-MetS was not associated (p = 0.48) with MC. Lowered FPG thresholds were significantly associated with risk for all major pregnancy outcomes. After adjusting for sociodemographic and anthropometric confounders, revised MetS remained the only significant risk predictor for LGA.

CONCLUSION

Pregnant women with T1 MetS in this population are at an increased risk for LGA and PTB and a reduced risk for SGA. We observed that a revised MetS definition with lower threshold for FPG compatible with GDM would provide a better estimation of MetS in pregnancy in relation to predicting LGA.

First Trimester Evaluation of Maternal Visceral Fat and Its Relationship with Adverse Pregnancy Outcomes

Obese women are more likely to experience pregnancy complications. The distribution of fat, and more particularly the rise in visceral fat, is well established to be more closely linked to the onset of cardiovascular disease and metabolic syndrome than obesity itself. We aim to examine the relationship between maternal visceral fat assessment in the first trimester and the appearance of adverse pregnancy outcomes. A prospective cohort study including 416 pregnant women was conducted. During the first trimester scan (11-13 + 6 weeks), all individuals had their visceral fat and subcutaneous thicknesses measured by ultrasonography. Blood samples were obtained, and maternal demographics and clinical information were documented. After delivery, the obstetric outcomes were evaluated. We contrasted two groups: one with healthy pregnancies and the other with adverse pregnancy outcomes (APO), defined as the development of at least one of the following complications: gestational diabetes mellitus, hypertensive disorders of pregnancy, abnormal fetal growth, preterm delivery or preterm premature rupture of membranes. Median maternal age was 33 and 34 years old for the uncomplicated and adverse pregnancy outcomes groups, respectively. We found that women with adverse pregnancy outcomes had higher VFT (median 30 vs. 26.5 mm, p = 0.001) and SFT (median 18.9 vs. 17.1 mm, p = 0.03). However, the visceral/subcutaneous fat ratio was not statistically different between groups. Finally, we performed a subanalysis for metabolic and placental vascular dysfunction complications. After performing a multivariate logistic regression analysis adjusted for maternal age, smoking, and mean arterial pressure, both the VFT (aOR 1.03, p < 0.001) and the ratio of visceral/subcutaneous fat (aOR 1.37, p = 0.04) were significantly associated with the development of adverse pregnancy outcomes; however, the associations of VFT and the VFT-to-SFT ratio were higher for the occurrence of gestational diabetes (aOR 1.07, p < 0.001; aOR 2.09, p = 0.001; respectively) and showed no relationships with placental complications. When conducting a first-trimester ultrasound assessment, sonographers may measure VFT without additional time or cost involved. Identification of pregnant women with increased VFT (>37 mm) may benefit from a close follow-up, especially for the development of gestational diabetes, independent of BMI.

The Relationship between Angiogenic Factors and Energy Metabolism in Preeclampsia

Antiangiogenic factors are currently used for the prediction of preeclampsia. The present study aimed to evaluate the relationship between antiangiogenic factors and lipid and carbohydrate metabolism in maternal plasma and placenta. We analyzed 56 pregnant women, 30 healthy and 26 with preeclampsia (including early and late onset). We compared antiangiogenic factors soluble Fms-like Tyrosine Kinase-1 (sfLt-1), placental growth factor (PlGF), and soluble endoglin (sEng)), lipid and carbohydrate metabolism in maternal plasma, and lipid metabolism in the placenta from assays of fatty acid oxidation, fatty acid esterification, and triglyceride levels in all groups. Antiangiogenic factors sFlt-1, sFlt-1/PlGF ratio, and sEng showed a positive correlation with triglyceride, free fatty acid, and C-peptide maternal serum levels. However, there was no relationship between angiogenic factors and placental lipid metabolism parameters. Free fatty acids were predictive of elevated sFlt-1 and sEng, while C-peptide was predictive of an elevated sFlt1/PlGF ratio. The findings in this study generate a model to predict elevated antiangiogenic factor values and the relationship between them with different products of lipid and carbohydrate metabolism in maternal serum and placenta in preeclampsia.

High total cholesterol and triglycerides levels increase arginases metabolism, impairing nitric oxide signaling and worsening fetoplacental endothelial dysfunction in gestational diabetes mellitus pregnancies

During human pregnancy, maternal physiological dyslipidemia (MPD) supports fetal development. However, some women develop maternal supraphysiological dyslipidemia (MSPD: increased total cholesterol (TC) and triglycerides (TG) levels). MSPD is present in normal and pregnancies with gestational diabetes mellitus (GDM). Both pathologies associate with fetoplacental endothelial dysfunction, producing alterations in nitric oxide (NO)-L-arginine/arginase metabolism. Nevertheless, the effect of MSPD on GDM, and how this synergy alters fetoplacental endothelial function is unknown, which is the aim of this study. 123 women at term of pregnancy were classified as MPD (n=40), MSPD (n=35), GDM with normal lipids (GDM- MPD, n=23) and with increased lipids (GDM-MSPD, n=25). TC ≥291 mg/dL and TG ≥275 mg/dL were considered as MSPD. Endothelial NO synthase (eNOS), human cationic amino acid transporter 1 (hCat1), and arginase II protein abundance and activity, were assayed in umbilical vein endothelial cells. In MSPD and MSPD-GDM, TC and TG increased respect to MPD and MPD-GDM. eNOS activity was reduced in MSPD and MSPD-GDM, but increased in MPD-GDM compared with MPD. No changes were observed in eNOS protein. However, decreased tetrahydrobiopterin levels were observed in all groups compared with MPD. Increased hCat1 protein and L-arginine transport were observed in both GDM groups compared with MPD. However, the transport was higher in GDM-MSPD compared to GDM-MPD. Higher Arginase II protein and activity were observed in MSPD-GDM compared with MPD. Thus, MSPD in GDM pregnancies alters fetal endothelial function associated with NO metabolism.

The relationship between hypertriglyceridemic waist circumference phenotype and gestational diabetes mellitus

AIMS

To investigate the correlation between hypertriglyceridemic waist circumference (HTWC) phenotype and gestational diabetes mellitus (GDM).

METHODS

A total of 1083 patients with gestational age ≤8 weeks were divided into four groups: normal triglyceride and waist circumference group (group A, n = 575), simple abdominal obesity group (group B, n = 317), simple high triglyceride group (group C, n = 125), and HTWC group (group D, n = 66). General information and serum biochemical indicators were measured and recorded. Analysis of variance (ANOVA) and logistic regression analysis were used to evaluate the relationship between HTWC with GDM.

RESULTS

The prevalence of GDM in the HTWC group was significantly greater than in the other three groups. After adjustment by multivariate logistic regression analysis, the proportion of GDM in the HTWC group was 1.753 times higher than in group A.

CONCLUSION

These findings suggest that there is a significant correlation between HTWC phenotype and GDM, indicating that the HTWC phenotype could be applied as a simple marker for identifying GDM risk factors.

Metabolic profile during pregnancy in BRISA birth cohorts of Ribeirão Preto and São Luís, Brazil

During pregnancy, metabolic changes that develop in women may increase the risk of diseases and conditions that may also harm the life of the growing fetus. The aim of the present study was to identify and compare the metabolic profile (MP) during pregnancy in two birth cohorts in 2010 in the cities of Ribeirão Preto (RP) and São Luís (SL), Brazil. Pregnant women (1393 in RP and 1413 in SL) were studied; information was obtained through questionnaires in addition to anthropometric, biochemical, and blood pressure measurements. Data are presented as means and proportions. To compare the characteristics of pregnant women in both cities, chi-squared and Student's t-tests were applied, with 5% significance level. Ribeirão Preto presented higher mean values than SL for pre-gestational body mass index (24.5 vs 23 kg/m², P<0.001), systolic (108.4 vs 102.8 mmHg, P<0.001) and diastolic (65.9 vs 61.8 mmHg, P<0.001) blood pressure, total cholesterol (226.3 vs 213.7 mg/dL, P<0.001) and fractions, and glycemia (84.5 vs 80.2 mg/dL, P<0.001), except for triglycerides (P=0.135). Women from RP also showed higher rates of pre-gestational overweight and obesity compared with SL (40.1 vs 25.8%). In the present study, pregnant women in RP had a worse gestational metabolic profile than those in SL, with higher pre-gestational excess weight, indicating that nutritional transition was more advanced in the more developed city.

Metabolic syndrome markers and risk of hyperglycemia in pregnancy: a cross-sectional cohort study

The aim was to assess the role of Metabolic Syndrome (MetS) diagnostic markers, recommended by three different guidelines, in the prediction of hyperglycemia in pregnancy. This cross-sectional cohort study included 506 non-diabetic women, with a singleton pregnancy, who underwent a diagnostic test for hyperglycemia at 24-28 weeks. Clinical, anthropometric, and laboratory data were obtained. The relationship between MetS markers and the risk of hyperglycemia was evaluated by backward stepwise logistic regression analysis (OR, 95% CI). The limit of statistical significance was 95% (p < 0.05). Triglycerides (TG) ≥ 150 mg/dL, blood pressure (BP) ≥ 130/85 mmHg, fasting glucose (FG) ≥ 100 mg/dL, and waist circumference (WC) > 88 cm were identified as independent risk factors for hyperglycemia in pregnancy. These results might help the selective screening of hyperglycemia in pregnancy.

The effect of caring intervention (physical activity, diet and counseling) on gestational diabetes for pregnant women with metabolic syndrome

OBJECTIVE

Metabolic syndrome and its indexes is one of the critical health problems during pregnancy. This study aimed to examine the effects of a care intervention program on pregnancy outcome in pregnant women with Metabolic Syndrome during 2017-2018.

METHODS

This randomized clinical trial study was conducted in 120 singleton pregnant women with metabolic syndrome. The participants were selected using purposive sampling method from pregnant women referred to two health centers of Babol. They were randomly divided in two control and intervention groups (60 samples in each group). Intervention group received one motivational interview session for 120 min, two consultation sessions with expert for nutritional recommendations based on Nutrition Guidelines of Ministry of Health for Pregnant Women. They were also theoretically and practically provided by three training sessions for physical activity and pregnancy exercises combining pelvic floor muscles, bodybuilding, muscle strengthening, stretching, and relaxation and walking activities. To follow up on the intervention, the researcher made a phone call with the participants in intervention group every 10 days to two weeks. Pregnancy outcomes were assessed using SPSS software.

RESULTS

The obtained results showed that there was a significant difference between the two groups in maternal complications including gestational diabetes, hospitalization due to gestational diabetes, nutritional diet for gestational diabetes, pregnancy weight gain and 2-hour post-prandial blood glucose test (p ≤ .01). There was no significant difference in terms of demographic, midwifery and metabolic syndrome indices between the intervention and control groups.

CONCLUSION

The results of the study indicated that intervention program improved the maternal pregnancy outcome such as gestational diabetes and weight gain during the pregnancy in the intervention group. This program had no adverse effects for the mother who is consistent with pregnancy health objectives.

Are maternal metabolic syndrome and lipid profile associated with preterm delivery and preterm premature rupture of membranes?

AIM

We aimed to evaluate the association of metabolic syndrome (MetS), its components and lipid profile in mid-pregnancy with preterm delivery and preterm premature rupture of membranes (PPROM).

METHODS

This prospective cohort study was conducted on 203 pregnant women between 24 and 28 weeks of gestation, undergoing gestational diabetes screening test with 50 g glucose challenge test (GCT). Fasting serum total cholesterol, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and triglyceride (TG) levels were measured during the week after GCT assessment. Information on the participants' pre-pregnancy weight, demographic/reproductive characteristics, and height and blood pressure (BP) measurements were documented at baseline entry into the study. Metabolic syndrome was defined as the co-existence of 3 or more of the following criteria: Body mass index (BMI) before pregnancy ≥ 30 kg/m², BP ≥ 130/85 mmHg, GCT ≥ 140 mg/dl, TG ≥ 150 mg/dl, and HDL-C ≤ 50 mg/dl. All participants were followed through routine prenatal care, up to delivery. Any deliveries or rupture of membranes of less than 37 weeks of pregnancy were considered preterm delivery and PPROM, respectively. Statistical analysis was performed by SPSS V.20, and p value of less than 0.05 was considered significant.

FINDINGS

MetS was detected in 10 (4.9%) of participants. Logistic regression analysis showed HDL-C levels, and hypertension were associated with spontaneous preterm delivery [(OR 0.952, 95% CI 0.910-0.995), (OR 1.629, 95% CI 1.554-1.709) respectively], but no statistically significant results were found for PPROM.

CONCLUSIONS

Low HDL-C levels and hypertension in mid-pregnancy are associated with the occurrence of spontaneous preterm deliveries, indicating that MetS and its components should be monitored more closely in pregnancy.

Postpartum metabolic syndrome after gestational hypertension and preeclampsia, a prospective cohort study

OBJECTIVE

We evaluated the 6-month postpartum risk of metabolic syndrome (MetS), a marker of future cardiovascular disease (CVD) risk, comparing women whose most recent pregnancies were complicated with gestational hypertension (GH) or preeclampsia (PE) versus those who had normotensive pregnancies.

STUDY DESIGN

This was a prospective cohort study in which women with GH or PE and normotensive women were actively enrolled during the first 12 weeks after delivery in Nairobi, Kenya. Participants were interviewed, blood pressures and anthropometric measurements including waist circumference obtained at enrollment and 6 months postpartum. Fasting lipid profile and plasma glucose were measured at 6 months postpartum. A generalized linear regression model with Poisson distribution was used to estimate crude relative risk (RR) of 6-month postpartum MetS and adjusted RR (ARR) after adjusting for apriori potential confounders.

RESULTS

Among 194 postpartum women, 63 (32%) had experienced GH or PE. Prevalence of MetS at 6 months postpartum was higher among women whose pregnancies were complicated with GH or PE (34.9%) compared to those who were normotensive (11.5%). GH and PE were associated with a 3-fold or greater risk of MetS (ARR) 3.01; 95% Confidence interval [CI] 1.58, 5.71; p < 0.001) overall and three of the five components, namely hypertension (ARR 3.35 [2.04, 5.51], p < 0.001), hypertriglyceridemia (ARR 3.25 [1.16-9.10], p = 0.01), and fasting hyperglycemia (ARR 6.20 [1.07-35.76], p = 0.03), compared to having normal blood pressures during pregnancy.

CONCLUSION

At 6  months postpartum, GH and PE were associated with three-fold or higher risk of MetS and especially hypertension, fasting hypertriglyceridemia, and fasting hyperglycemia.

Skin disease related to metabolic syndrome in women

Sex hormones are involved in pathways of metabolic syndrome (MetS), an observation supported by animal studies. The relationships of sex hormones with components of MetS, such as insulin resistance and dyslipidemia, have been studied in pre- and postmenopausal women. High testosterone, low sex hormone-binding globulin, and low estrogen levels increase the risks of MetS and type 2 diabetes in women. Cutaneous diseases that are sex hormone mediated, such as polycystic ovary syndrome, acanthosis nigricans, acne vulgaris, and pattern alopecia, have been associated with insulin resistance and increased risk for MetS. Furthermore, inflammatory skin conditions, such as hidradenitis suppurativa and psoriasis, increase the risk for MetS. Patients with such skin conditions should be followed for metabolic complications, and early lifestyle interventions toward these populations may be warranted.

Skeletal muscle as a protagonist in the pregnancy metabolic syndrome

The pregnant woman normally shows clinical manifestations similar to a metabolic syndrome (MS), due to her metabolic and hemodynamic adaptations in order to share nutrients with the child. If those adjustments are surpassed, a kind of pregnancy MS (PregMS) could appear, characterized by excessive insulin resistance and vascular maladaptation. Skeletal muscle (SKM) must be a protagonist in the PregMS: SKM strength and mass have been associated inversely with MS incidence in non-pregnant patients, and in pregnant women muscular activity modulates metabolic and vascular adaptations that favor better outcomes. Of note, a sedentary lifestyle affects exactly in the other way. Those effects may be explained not only by the old paradigm of SKM being a great energy consumer and store, but because it is an endocrine organ whose chronic activity or deconditioning correspondingly releases myokines modulating insulin sensitivity and cardiovascular adaptation, by direct or indirect mechanisms not well understood. In this document, we present evidence to support the concept of a PregMS and hypothesize on the role of the SKM mass, fiber types composition and myokines in its pathophysiology. Also, we discuss some exercise interventions in pregnancy as a way to test our hypotheses.

Appropriate Interventions for Pregnant Women with Indicators of Metabolic Syndrome on Pregnancy Outcomes: A Systematic Review

Metabolic syndrome (MetS), a series of symptoms, including abdominal obesity, impaired glucose tolerance and insulin metabolism, hypertension, and dyslipidemia, is considered as the risk of developing cardiovascular disease and diabetes that can predispose a pregnant women to serious health problem, women in the developed as well as the developing countries. This study was aimed to investigate the effects of appropriate interventions on pregnant women with indicators of MetS to further improve the outcome of pregnancy. This systematic review was performed to extract articles of randomized controlled trials (RCT) on pregnant women with indicators of (MetS) and focusing on physical activity, dietary or lifestyle interventions on maternal health or perinatal outcomes, with searching in the Web of Science, PubMed, CDSR, Scopus, and Google Scholar were investigated. Two researchers independently evaluated the quality of the studies, being presented in all the articles and ranked the studies as high/low quality; the level of evidence was based on the number of high-quality studies and the coordination of the obtained results. Then, 17 articles, which met the inclusion criteria, were selected; among these, 7 articles studied the physical activity, 3 articles reviewed diets, 6 probed the lifestyle interventions, and 1 article was on counseling. In general, evidence suggested how the physical activity and proper diet impacts on proper weight gain during pregnancy, prevents maternal complications, and improves the outcome of pregnancy. According to the results of this systematic review, proper interventions during pregnancy can have a positive effect on maternal weight gain and the general health condition of pregnant women with indicators of MetS.

Maternal serum lipid levels, oxidative stress and antioxidant activity in pre-eclampsia patients from Southwest India

OBJECTIVE

A study was carried out to evaluate the effects of metabolic syndrome components and oxidative stress factors among preeclamptic women from South West India.

STUDY DESIGN

A case-control study was carried out by enrolling fifty pre-eclampsia cases and hundred low-risk pregnant women within the age group of 18-40 years, at 28-34 weeks of pregnancy. The fasting glucose level, fasting insulin level, insulin resistance, total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), malondialdehyde, the ferric reducing ability of plasma (FRAP assay), cardiac output and aortic wall distensibility were measured.

MAIN OUTCOME MEASURES

There was a significant rise in the fasting blood glucose, fasting insulin, insulin resistance levels, total cholesterol, triglycerides, LDL, and antioxidant levels in pre-eclamptic women (p < 0.001). The cardiac output and aortic wall distensibility were observed to be low in the cases.

CONCLUSION

We conclude that abnormal lipid metabolism and high lipid peroxide concentrations observed in pre-eclampsia may result in oxidative stress and vascular dysfunction.

Effects of Selenium Supplementation on Gene Expression Levels of Inflammatory Cytokines and Vascular Endothelial Growth Factor in Patients with Gestational Diabetes

Selenium is known to exert multiple beneficial effects including anti-inflammatory actions. The aim of the study was to evaluate the effects of selenium supplementation on gene expression levels of inflammatory cytokines and vascular endothelial growth factor (VEGF) in women with gestational diabetes (GDM). This randomized double-blind, placebo-controlled trial was carried out among 40 subjects diagnosed with GDM aged 18-40 years old. Subjects were randomly allocated into two groups to receive either 200 μg/day selenium supplements (n = 20) or placebo (n = 20) for 6 weeks. Gene expression of inflammatory cytokines and VEGF were assessed in lymphocytes of GDM women with RT-PCR method. Results of RT-PCR indicated that after the 6-week intervention, compared with the placebo, selenium supplementation downregulated gene expression of tumor necrosis factor alpha (TNF-α) (P = 0.02) and transforming growth factor beta (TGF-β) (P = 0.01), and upregulated gene expression of VEGF (P = 0.03) in lymphocytes of patients with GDM. There was no statistically significant change following supplementation with selenium on gene expression of interleukin (IL)-1β and IL-8 in lymphocytes of subjects with GDM. Selenium supplementation for 6 weeks in women with GDM significantly decreased gene expression of TNF-α and TGF-β, and significantly increased gene expression of VEGF, but did not affect gene expression of IL-1β and IL-8.

Combined Metabolomic Analysis of Plasma and Urine Reveals AHBA, Tryptophan and Serotonin Metabolism as Potential Risk Factors in Gestational Diabetes Mellitus (GDM)

Gestational diabetes mellitus during pregnancy has severe implications for the health of the mother and the fetus. Therefore, early prediction and an understanding of the physiology are an important part of prenatal care. Metabolite profiling is a long established method for the analysis and prediction of metabolic diseases. Here, we applied untargeted and targeted metabolomic protocols to analyze plasma and urine samples of pregnant women with and without GDM. Univariate and multivariate statistical analyses of metabolomic profiles revealed markers such as 2-hydroxybutanoic acid (AHBA), 3-hydroxybutanoic acid (BHBA), amino acids valine and alanine, the glucose-alanine-cycle, but also plant-derived compounds like sitosterin as different between control and GDM patients. PLS-DA and VIP analysis revealed tryptophan as a strong variable separating control and GDM. As tryptophan is biotransformed to serotonin we hypothesized whether serotonin metabolism might also be altered in GDM. To test this hypothesis we applied a method for the analysis of serotonin, metabolic intermediates and dopamine in urine by stable isotope dilution direct infusion electrospray ionization mass spectrometry (SID-MS). Indeed, serotonin and related metabolites differ significantly between control and GDM patients confirming the involvement of serotonin metabolism in GDM. Clustered correlation coefficient visualization of metabolite correlation networks revealed the different metabolic signatures between control and GDM patients. Eventually, the combination of selected blood plasma and urine sample metabolites improved the AUC prediction accuracy to 0.99. The detected GDM candidate biomarkers and the related systemic metabolic signatures are discussed in their pathophysiological context. Further studies with larger cohorts are necessary to underpin these observations.

Gynecologic and andrologic dermatology and the metabolic syndrome

The relationship of sex hormones to obesity and inflammation has been extensively studied. Research on endogenous and exogenous sex steroids, including studies on animal models of metabolic syndrome (MetS), has indicated that sex hormones are involved in metabolic pathways relevant to MetS. Lower testosterone levels in men and higher levels in women increase risks of MetS and type 2 diabetes mellitus (T2DM). Lower levels of sex hormone-binding globulin increase risks of MetS and T2DM in both sexes. Skin diseases that are sex hormone mediated, such as polycystic ovary syndrome, acanthosis nigricans, acne vulgaris, and pattern alopecia, have been associated with insulin resistance. Insulin resistance increases the risk for metabolic and potentially cardiovascular complications, and patients with such skin diseases should be followed for a prolonged time to determine whether they develop these complications. Early intervention may help delay or prevent the onset of T2DM and decrease cardiovascular risks.

Associations of lipid levels during gestation with hypertensive disorders of pregnancy and gestational diabetes mellitus: a prospective longitudinal cohort study

OBJECTIVE

To assess associations of elevated lipid levels during gestation with hypertensive disorders of pregnancy (HDP) and gestational diabetes mellitus (GDM).

METHODS

This prospective cohort study was conducted in a tertiary maternal hospital in Shanghai, China from February to November 2014. Lipid constituents, including triglycerides (TGs), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c) and high-density lipoprotein cholesterol (HDL-c) of 1310 eligible women were assessed in the first (10-13+ weeks), second (22-28 weeks) and third (30-35 weeks) trimesters consecutively. Associations of lipid profiles with HDP and/or GDM outcomes were assessed.

RESULTS

Compared with the normal group, maternal TG concentrations were higher in the HDP/GDM groups across the three trimesters (p<0.001); TC and LDL-c amounts were only higher in the first trimester for the HDP and GDM groups (p<0.05). HDL-c levels were similar in the three groups. Compared with intermediate TG levels (25-75th centile), higher TG amounts (>75th centile) were associated with increased risk of HDP/GDM in each trimester with aORs (95% CI) of 2.04 (1.41 to 2.95), 1.81 (1.25 to 2.63) and 1.78 (1.24 to 2.54), respectively. High TG elevation from the first to third trimesters (>75th centile) was associated with increased risk of HDP, with an aOR of 2.09 (1.16 to 3.78). High TG elevation before 28 weeks was associated with increased risk of GDM, with an aOR of 1.67 (1.10 to 2.54). TG elevation was positively correlated with weight gain during gestation (R=0.089, p=0.005).

CONCLUSIONS

Controlling weight gain during pregnancy could decrease TG elevation and reduce the risk of HDP/GDM. TGs could be used as follow-up parameters during complicated pregnancy, while other lipids are meaningful only in the first trimester.

Remodeling of the gut microbiota and structural shifts in Preeclampsia patients in South China

Preeclampsia (PE) is one of the pregnancy metabolic diseases. Since Gut microbiota play important roles in the hosts' metabolism, it is necessary to investigate the gut microbiota in PE patients, so that some intestinal dysbiosis might be detected as a biomarker for PE early diagnosis or as a target for intervention. One hundred subjects were categorized into four groups: 26 PE patients in late pregnancy, healthy individuals in early, middle, and late pregnancy (26/24/24 women). Gut microbiota were analyzed by sequencing the V4 region of the 16S rDNA gene using Illuminal MiSeq. Data were analyzed by multivariate statistics. Bacteroidetes was the dominant bacterium (47.57-52.35%) in the pregnant women in South China. Tenericutes increased while Verrucomicrobia almost disappeared in late pregnancy. In the PE patients, there was an overall increase in pathogenic bacteria, Clostridium perfringens (p = 0.03) and Bulleidia moorei (p = 0.00) but a reduction in probiotic bacteria Coprococcus catus (p = 0.03). Our research suggests that there is a significant structural shift of the gut microbiota in PE patients, which might be associated with the occurrence and development of the disease. However, further studies are required to understand the underlying mechanisms.

Clustering of metabolic risk factors and adverse pregnancy outcomes: a prospective cohort study

BACKGROUND

The relative contributions of a cluster of metabolic risk factors to pregnancy complications are not fully understood. We investigated the correlation between clustering of metabolic risk factors and adverse pregnancy outcomes.

METHODS

This prospective cohort study was performed on pregnant women who sought health care during their whole gestation in a women's and children's hospital. The pregnancy outcomes were also followed. Pre-pregnancy overweight/obesity, as well as pregnancy high triglycerides, low high-density lipoprotein-cholesterol, hyperglycemia and raised blood pressure were defined as metabolic risk factors. Adverse pregnancy outcomes included preterm delivery, small/large for gestational age, preeclampsia, gestational diabetes mellitus, neonatal asphyxia and foetal demise. Stratified analyses were conducted on a total of 5535 women according to classification in each metabolic risk factor. The adjusted odds ratio (OR) for adverse pregnancy outcomes according to the number of clustering metabolic factors was calculated using the logistic regression analysis.

RESULTS

The number of metabolic risk factors and adverse pregnancy outcomes were positively correlated (P_trend  < 0.001). Compared with women without a metabolic risk factor, women with one metabolic risk factor had a risk (OR = 1.67 95%CI 1.42-1.96) of adverse pregnancy outcomes. Women with a cluster of two metabolic risk factors tended to develop more adverse pregnancy outcomes (OR = 3.32 95% CI 2.69-4.10), and the risk was much higher in women with a cluster of three or more metabolic risk factors (OR = 10.40 95%CI 7.37-14.69).

CONCLUSIONS

Pregnant women with a cluster of metabolic risk factors are more likely to have adverse pregnancy outcomes. Copyright © 2016 John Wiley & Sons, Ltd.

A 'High Risk' Lifestyle Pattern Is Associated with Metabolic Syndrome among Qatari Women of Reproductive Age: A Cross-Sectional National Study

This study investigated the effect of lifestyle patterns, as a combination of diet, physical activity and smoking, on Metabolic Syndrome (MetS) among Qatari women of childbearing age (n = 418), a population group particularly vulnerable to the health sequela of this syndrome. Using data from the National WHO STEPwise survey conducted in Qatar in 2012, Principal Component Factor Analysis was performed to derive lifestyle patterns with survey variables related to the frequency of consumption of 13 foods/food groups, physical activity levels, and smoking status. MetS was diagnosed using ATPIII criteria. Three lifestyle patterns were identified: 'High Risk' pattern, characterized by intakes of fast foods, sweets and sugar sweetened beverages, in addition to lower levels of physical activity and higher smoking prevalence; 'Prudent' pattern, driven mainly by higher intakes of fruits, vegetables, fish, and whole grains; and 'Traditional' pattern which included beans, meat, dairy products, and a low prevalence of smoking. Among these three lifestyle patterns, only the 'High Risk' was associated with MetS, whereby subjects belonging to the third tertile of this pattern's score had 2.5 times the odds of MetS compared to those belonging to the first tertile. The findings of this study demonstrated the synergy among high risk behaviors among Qatari women in increasing the odds of MetS; the latter being a major risk factor for cardiovascular diseases.

Prevalence of metabolic syndrome in non-diabetic, pregnant Angolan women according to four diagnostic criteria and its effects on adverse perinatal outcomes

BACKGROUND

Metabolic syndrome (MetS) is a cluster of risk factors for type 2 diabetes (Type2 DM) and cardiovascular diseases (CVD), and its prevalence varies based on region, population, and sex. Newborns of women with MetS have a greater risk of adverse perinatal outcomes. This study explores the prevalence of metabolic syndrome in non-diabetic, pregnant Angolan women and the adverse perinatal outcomes associated with it.

METHODS

This cross-sectional study collected the demographic, anthropometric and clinical data of 675 pregnant women in the maternity ward of General Hospital in Huambo, Angola. Metabolic syndrome was defined using four criteria: the third report of the National Cholesterol Education Program Adult Treatment Panel (ATPIII), the Joint Interim Statement (JIS), and definitions by both Bartha et al. and Chatzi et al.

RESULTS

The crude prevalence of metabolic syndrome was 36.6 % based on the JIS definition, 29.2 % based on NCEP ATPIII, 12.6 % based on Chatzi et al. and 1.8 % based on Bartha et al. In general, the prevalence of adverse perinatal outcomes was 14.1 %.

CONCLUSIONS

There was a high prevalence of metabolic syndrome, depending on the criteria used, and thus a great need to harmonize the criteria and cutoff points. Perinatal adverse outcomes were higher in pregnant women with metabolic syndrome.

Maternal lipid levels during pregnancy and gestational diabetes: a systematic review and meta-analysis

BACKGROUND

Lipid levels during pregnancy in women with gestational diabetes mellitus (GDM) have been extensively studied; however, it remains unclear whether dyslipidaemia is a potential marker of preexisting insulin resistance.

OBJECTIVE

To evaluate the relationship between lipid measures throughout pregnancy and GDM.

SEARCH STRATEGY

We searched PubMed-MedLine and SCOPUS (inception until January 2014) and reference lists of relevant studies.

SELECTION CRITERIA

Publications describing original data with at least one raw lipid (total cholesterol, high-density lipoprotein cholesterol [HDL-C], low-density lipoprotein cholesterol [LDL-C], or triglyceride) measurement during pregnancy in women with GDM and healthy pregnant controls were retained.

DATA COLLECTION AND ANALYSIS

Data extracted from 60 studies were pooled and weighted mean difference (WMD) in lipid levels was calculated using random effects models. Meta-regression was also performed to identify sources of heterogeneity.

MAIN RESULTS

Triglyceride levels were significantly elevated in women with GDM compared with those without GDM (WMD 30.9, 95% confidence interval [95% CI] 25.4-36.4). This finding was consistent in the first, second and third trimesters of pregnancy. HDL-C levels were significantly lower in women with GDM compared with those without GDM in the second (WMD -4.6, 95% CI -6.2 to -3.1) and third (WMD -4.1, 95% CI -6.5 to -1.7) trimesters of pregnancy. There were no differences in aggregate total cholesterol or LDL-C levels between women with GDM and those without insulin resistance.

AUTHOR'S CONCLUSIONS

Our meta-analysis shows that triglycerides are significantly elevated among women with GDM compared with women without insulin resistance and this finding persists across all three trimesters of pregnancy.

Preconception metabolic indicators predict gestational diabetes and offspring birthweight

Pregnancy conditions such as gestational diabetes (GDM) and macrosomia lead to an increased risk of diabetes and cardiovascular disease in the offspring, perpetuating a cycle of poor health. We hypothesized that (1) pre-pregnancy indicators of metabolism would be associated with GDM and birthweight; and (2) the lipid accumulation product (LAP; incorporating waist circumference and triglycerides) and visceral adiposity index (VAI; incorporating waist circumference, triglycerides, and HDL-c) would be better predictors of GDM and birthweight than other indicators. Data from the Cardiovascular Risk in Young Finns Study were linked to the Finnish birth registry for 349 women. BMI, triglycerides, waist circumference, insulin, HOMA-IR, LAP, and VAI at the visit prior to the pregnancy were examined as predictors of GDM and large-for-gestational-age (LGA) using logistic regression with adjustment for age, parity, and smoking. Waist circumference was the strongest predictor of GDM (adjusted odds ratio [aOR] 1.66, 95% confidence interval 1.16-2.38) and LGA (aOR 1.41, 1.00-1.99). For GDM, all markers had similar discrimination; for LGA, the area under the receiver operating curve for waist circumference was significantly higher than for BMI (p < 0.01). This analysis suggests that pregnancy and even offspring health is affected by risk factors outside the immediate time period of pregnancy.

Oxidative stress and antioxidant status in patients with late-onset gestational diabetes mellitus

The relationship between late-onset gestational diabetes mellitus [GDM] and oxidative stress is not well known, and the importance of the oxidant/antioxidant equilibrium in the clinical evolution and its complications require elucidation. The aim of the study was to evaluate the relationships between maternal levels of markers of oxidative stress in women with late-onset GDM that, potentially, may have considerable clinical implications in the pathogenesis and/or the evolution of GDM. Pregnant women (n = 78; 53 with GDM, 25 controls), between the 24th and 29th week of gestation, were enrolled. Both groups were analysed for demographic data, perinatal and obstetrics outcomes together with the levels of the marker's oxidative stress and antioxidant status. Control versus patient results in the univariate analysis were the following: pre-gestational body mass index [BMI] 23.31 ± 4.2 vs. 27.13 ± 4.6 kg/m(2) (P = 0.001); weeks at delivery 39.2 ± 3.05 vs. 38.9 ± 1.8 (P = 0.09); Caesarean delivery 12.5 vs. 43% (P = 0.004); macrosomia 4 vs. 9.4% (P = 0.6); lipoperoxides [LPO] 2.06 ± 1.00 vs. 3.14 ± 1.55 μmol/mg (P = 0.001); catalase 3.23 ± 1.41 vs. 2.52 ± 1.3 nmol/min/ml (P = 0.03); superoxide dismutase [SOD] 0.11 ± 0.04 vs. 0.08 ± 0.01 U/ml (P = 0.0003); glutathione peroxidase [GPX] 0.03 ± 0.006 vs. 0.025 ± 0.006 nmol/min/ml (P = 0.01); glutathione reductase [GSH] 0.004 ± 0.002 vs. 0.004 ± 0.004 nmol/min/ml (P = 0.9)]; and glutathione transferase [GST] 0.0025 ± 0.0012 vs. 0.0027 ± 0.00017 nmol/min/ml (P = 0.7). Multivariate analysis showed catalase might have a protective effect against GDM development and LPO seems to be a risk factor for the disease. These data suggest an increase in oxidative stress and a decrease in antioxidative defence in women with late-onset GDM and, as such, may have considerable clinical implications in the pathogenesis and/or the course of the pregnancy in these patients.

Oral metformin treatment prevents enhanced insulin demand and placental dysfunction in the pregnant rat fed a fructose-rich diet

The intake of a fructose-rich diet (FRD) in the normal female rat induces features similar to those observed in the human metabolic syndrome phenotype. We studied the impact of FRD administration to mothers on pregnancy outcome. On gestational day (Gd) zero rats were assigned to either group: ad libitum drinking tap water alone (normal diet, ND) or containing fructose (10% w/vol; FRD) through pregnancy; all rats were fed a Purina chow diet ad libitum ND and FRD rats were daily cotreated or not with metformin (60 mg/Kg/day oral; ND + MF and FRD + MF) and submitted to a high glucose load test on Gd 14. Additionally, placentas from different groups were studied on Gd 20. Data indicated that: (1) although FRD rats well tolerated glucose overload, their circulating levels of insulin were significantly higher than in ND rats; (2) the mesometrial triangle blood vessel area was significantly lower in placentas from FRD than ND dams; (3) the detrimental effects of FRD administration to mothers were ameliorated by metformin cotreatment. Our study suggests that excessive intake of fructose during pregnancy enhanced the risk for developing gestational diabetes and subsequent preeclampsia, and that metformin prevented the poor pregnancy outcome induced by FRD.

Inflammation and cardiovascular risk in women with preterm labor

BACKGROUND

Women with a history of preterm delivery have about twice the normal risk of cardiovascular disease (CVD). Mechanisms underlying this association are not well understood. The aim of the present study was to evaluate the relationships between selected metabolic CVD risk factors and markers of both systemic inflammation and endothelial dysfunction in women with spontaneous preterm labor (sPL).

METHODS

This was a case-control study in a university tertiary referral center. Forty pregnant women with sPL were compared to 50 controls during gestation. Maternal serum triglycerides, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), total cholesterol, glycemia, insulinemia, homeostasis model assessment (HOMA), leptin, tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), soluble vascular cell adhesion molecule (sVCAM), soluble intercellular adhesion molecule (sICAM), selectin, and myeloperoxidase (MPO) were measured.

RESULTS

Gestational age at study was similar in both groups (31.56±3.14 weeks of gestation vs. 31.27±2.14 weeks of gestation, p=0.62, for the control and the sPL groups, respectively). Body mass index (BMI) (21.72±2.99 vs. 23.56±3.80, p=0.01), all cholesterol fractions (HDL-C 53.44±18.22 vs. 68.32±18.38, p=0.0003; LDL-C 125.71±35.56 vs. 142.15±36.07, p=0.03, and total cholesterol 219.55±32.29 vs. 240.38±40.01, p=0.009) and MPO (3.07±0.63 vs. 3.48±0.32, p=0.0009) were significantly lower in women with sPL. Serum levels of IL-6 (0.61±0.46 vs. 0.33±0.46, p=0.007) and the ratio of total cholesterol/HDL-C (4.52±1.48 vs. 3.77±1.37, p=0.01) were significantly increased and correlated each other (r=0.21, p=0.04). Logistic regression showed that the best predictive model for sPL (R(2)=0.36, p=0.001) included BMI and total cholesterol.

CONCLUSIONS

A combination of low maternal BMI, low cholesterol levels, and high total cholesterol/HDL-C ratio is present in women with sPL and is related to inflammation.

Molecular and vascular targets in the pathogenesis and management of the hypertension associated with preeclampsia

Normal pregnancy is associated with significant hemodynamic changes and vasodilation of the uterine and systemic circulation in order to meet the metabolic demands of the mother and developing fetus. Preeclampsia (PE) is one of the foremost complications of pregnancy and a major cause of maternal and fetal mortality. The pathophysiological mechanisms of PE have been elusive, but some parts of the puzzle have begun to unravel. Genetic factors such as leptin gene polymorphism, environmental and dietary factors such as Ca(2+) and vitamin D deficiency, and co-morbidities such as obesity and diabetes may increase the susceptibility of pregnant women to develop PE. An altered maternal immune response may also play a role in the development of PE. Although the pathophysiology of PE is unclear, most studies have implicated inadequate invasion of cytotrophoblasts into the uterine artery, leading to reduced uteroplacental perfusion pressure (RUPP) and placental ischemia/hypoxia. Placental ischemia induces the release of biologically active factors such as growth factor inhibitors, anti-angiogenic factors, inflammatory cytokines, reactive oxygen species, hypoxia-inducible factors, and antibodies to vascular angiotensin II (AngII) receptor. These bioactive factors could cause vascular endotheliosis and consequent increase in vascular resistance and blood pressure, as well as glomerular endotheliosis with consequent proteinuria. The PE-associated vascular endotheliosis could be manifested as decreased vasodilator mediators such as nitric oxide, prostacyclin and hyperpolarizing factor and increased vasoconstrictor mediators such as endothelin-1, AngII and thromboxane A₂. PE could also involve enhanced mechanisms of vascular smooth muscle contraction including intracellular Ca(2+), and Ca(2+) sensitization pathways such as protein kinase C and Rho-kinase. PE-associated changes in the extracellular matrix composition and matrix metalloproteinases activity also promote vascular remodeling and further vasoconstriction in the uterine and systemic circulation. Some of these biologically active factors and vascular mediators have been proposed as biomarkers for early prediction or diagnosis of PE, and as potential targets for prevention or treatment of the disease.

Are insulin resistance index, IGF-1 and metabolic syndrome components correlates with severe preeclampsia?

OBJECTIVE

Analyse the relation between insulin resistance and severe preeclampsia (SPE).

METHODS

Case control study paired by body mass index and gestational age; including 16 patients with severe SPE and 16 normotensive controls. Insulin resistance was assessed through the HOMA-IR and QUICKI-IS indexes.

RESULTS

There was no significant difference between the groups regarding the HOMA-IR and QUICKI-IS indexes and HDL cholesterol. Triglyceride levels were higher and the IGF-1 was lower in the SPE group than in the control group.

CONCLUSIONS

There were no differences in the insulin resitance indexes between the group with SPE and normal controls.

The metabolic syndrome and the risks of unfavourable outcome of pregnancy

A metabolikus szindróma jellemzői a hasi elhízás, a magas vérnyomás, az éhhomi glükóz és dyslipidaemia együttes előfordulása. A vizsgálat célja, hogy feltárja a metabolikus anyagcserezavar és egyes terhességi szövődmények kapcsolatát. Anyag és módszer: A releváns kódok alapján retrospektíve leválogatott digitális adatbázisból a 2005–2008 közötti vizsgált időszakban (4 év) a kórházi dokumentációkban 5869 várandós anya gondozási adataival rendelkeztek. Százhetvenkettő anya (2,9%) esetében a várandósságuk első harmadában a metabolikus tünetegyüttes jellemzői szerepeltek. Ezen betegek adatait részletesen megvizsgálták, feldolgozták és releváns adataikat a többi várandós hasonló dokumentációival összehasonlították. Eredmények: A metabolikus tünetegyüttes tüneteit mutató csoportban a koraszülési arány 15,1% (26/172) volt, míg a metabolikus szindrómától mentes esetekben az idő előtti születés csupán 11,7% volt [OR: 1,52 (95%-os CI: 0,996–2,33) p=0,051]. Az anyagcserezavarban érintettek csoportjában 32 anyánál intrauterin növekedési zavart észleltek, míg ezen tünetegyüttes nélküli esetekben ez csupán 3,6%-ban (205/5697) fordult elő [OR: 6,38 (95%-os CI: 4,24–9,61) p<0,001)]. A vizsgált csoportban 47 praeeclampsiával szövődött várandósságot észleltek (27,3%), szemben a beteganyaguk további részével, ahol a terhességi mérgezés előfordulása 4,7% volt [OR: 7,93 (95%-os CI: 5,54–11,33) p<0,001]. A metabolikus tünetegyüttesben szenvedők körében 67 (38,2%) olyan beteg volt, aki több mint egy, a betegségre jellemző szülészeti szövődményben szenvedett. A kontrollcsoportban ugyanez az arány 17,0%-nak adódott [OR: 3,11 (2,27–4,26) p<0,001]. A metabolikus szindróma által érintett csoportban csupán 47 (27,3%) olyan esetet találtak, akik várandósságuk és szülésük alatt tünetmentesek voltak, míg az 5697 anyából, akiknél az első terhességi harmadban a metabolikus tünetegyüttes jeleit nem észlelték, szignifikánsan kedvezőbb arányban (74,1%, 4220 várandós) voltak olyan anyák, akik minden szövődmény nélkül viselték várandósságukat [OR: 0,132 (0,09–0,18) p<0,001]. Következtetések: A metabolikus szindróma irodalmi adatok alapján és saját megfigyeléseik szerint is jelentős szerepet játszik a szövődményes várandósságok kialakulásában, elsősorban a gyulladásos faktorok és a fokozott trombóziskészség provokálásával. Számos irodalmi adat utal arra, hogy a metabolikus tünetegyüttes esetén a már a koncepció idején alkalmazott heparinkezelés eredményes lehet. 2007-ben prospektív vizsgálatot indítottak azzal a céllal, hogy megismerjék, vajon az alacsony molekulatömegű heparin megelőző célú kezelés, segít-e elkerülni ennek az anyagcserezavarnak a kedvezőtlen következményeit? Reményeik szerint a 2010-es évektől a heparinkezelés eredményeiről adatokkal rendelkeznek.

Association of Remote Hypertension in Pregnancy With Coronary Artery Disease

Because hypertensive pregnancies have been associated with increased cardiovascular disease, we aimed to identify whether angiographically characterized coronary artery disease differed in women with previous normotensive pregnancies or hypertensive pregnancies (HPs). The study group included 217 parous women, aged 60.9±9.2 (SD) years, who required coronary angiography between January 2006 and December 2007, 36.8±9.9 and 28.8±10.5 years after their first and last pregnancy, respectively; 146 had normotensive pregnancies and 71 had ≥1 HP, according to a questionnaire including reproductive history and cardiovascular risks. Body mass index, smoking, and frequency of diabetes were similar in both groups. Chronic hypertension (93% versus 78%; P =0.007), hyperlipidemia (82% versus 69%; P =0.049), and premature familial cardiovascular disease (42% versus 20%; P =0.001) prevailed in HPs. Participants with HPs were younger (58.9±8.3 versus 61.9±9.6 years; P =0.025) than participants with normotensive pregnancies. Although 49% of all participants had hemodynamically significant coronary artery disease (≥70% stenosis), no differences were observed between groups in the number of stenotic arteries; however, their number increased by 28% and 22% over a 10-year period in HPs and normotensive pregnancies, respectively ( P =0.034). Multivariate analysis showed that HPs had a nonsignificant risk of having coronary artery disease (odds ratio: 1.21; 95% CI: 0.64 to 2.28), and being a current smoker (odds ratio: 4.13; 95% CI: 1.85 to 9.25), a diabetic (odds ratio: 2.29; 95% CI: 1.85 to 9.25), or having a family history of premature cardiovascular disease (odds ratio: 2.34; 95% CI: 1.17 to 2.39) significantly increased the risk of coronary artery disease. This study demonstrates that women with HPs have earlier coronary disease, probably related to intermediate cardiovascular risks that have a gestational expression.

A new metabolic scoring system for analyzing the risk of hypertensive disorders of pregnancy

OBJECTIVE

The aim of this study was to investigate the relationship between some components of metabolic syndrome (MS) and pregnancy induced hypertension (PIH).

STUDY DESIGN

Forty-one patients with PIH (gestational hypertension or preeclampsia) after 32 weeks of gestation were compared with 97 normotensive pregnant women. Metabolic scores (0-4) were created using standard deviations in normotensive cases: mean level + 1SD for BMI (>31 kg/m(2)), mean level + 1SD for triglyceride (>287 mg/dl), mean level + 1SD for fasting serum glucose (>90 mg/dl)) and mean level - 1SD for HDL (<48 mg/dl).

RESULTS

The mean values for BMI (31.6 +/- 5.7 vs. 27.7 +/- 3.6; P < 0.0001), fasting triglyceride (341 +/- 129 vs. 220.7 +/- 67; P < 0.0001) and glucose (87.5 +/- 17.1 vs. 79.6 +/- 10.4; P = 0.0009) were higher in hypertensive group. The proportions of the women with a positive result for each of the components were significantly higher in the group of PIH. The percentage of the cases having 2 (35.2 vs. 8.2%; P = 0.0002) and 3 or more (27 vs. 4.1%; P = 0.0003) components of MS was higher in the hypertensive group and the percentage of the cases with none of these factors was high in the normotensive group (10.8 vs. 56.7%; P < 0.0001).

CONCLUSION

The presence of multiple components of MS may be a risk factor in the development of PIH. New scoring systems according to the gestational age might be useful in analyzing the risk of PIH.
