Maternal hemoglobin A1c and left ventricular hypertrophy in infants of mothers with pre-gestational diabetes. J Matern Fetal Neonatal Med 2024; 37:2407038. [PMID: 39322428 DOI: 10.1080/14767058.2024.2407038] [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: 01/23/2024] [Revised: 09/04/2024] [Accepted: 09/16/2024] [Indexed: 09/27/2024]
Abstract
OBJECTIVE Maternal hemoglobin A1c (HbA1c) has been suggested to be a predictor of left ventricular hypertrophy (LVH) in the offspring of mothers with pre-gestational diabetes mellitus, although there is little data supporting this contention. We aimed to assess the relationship between maternal HbA1c and postnatal LVH. METHODS We performed a retrospective cohort study of infants born to mothers with pre-gestational diabetes mellitus from 2015 to 2021 at our institution. The primary predictor was maternal HbA1c; neonatal left ventricular mass (LVM) z-score was the primary outcome; LVM z-score was considered as both a continuous variable and a binary variable by dichotomizing at 4 to define LVH. Additionally, we used linear regression to determine the relationship between maternal HbA1c and LVM z-score. RESULTS There were 116 infants who met inclusion (50% female). Mean maternal HbA1c was generally higher in infants with LVH compared to those without LVH (8.2% with LVH vs. 7.2% without LVH [p = 0.009] in the second trimester, and 7.8% vs. 7.0% [p = 0.025] in the third trimester; no significant difference for first trimester). A greater percentage of infants with LVH were intubated (36% vs. 6%, p < 0.001) and had longer average days of hospitalization (9 vs. 5, p = 0.044). Second and third trimester HbA1c was weakly associated with LVM z-score (R2 = 0.063, p < 0.001 and R2 = 0.068, p < 0.001, respectively); first trimester HbA1c was not significantly predictive of LVM z-score. CONCLUSION Second and third trimester HbA1c is modestly predictive of LVH in infants born to mothers with pre-gestational diabetes mellitus.

Abstract
Introduction Diabetes in pregnancy is associated with impaired offspring cardiac function. The objective of this systematic review was to determine the effect of diabetes in pregnancy on cardiac function in the offspring measured by echocardiography. Methods PubMed, Embase, Cochrane CENTRAL and Web of Science databases were searched from 1992 to June 27, 2023. Studies reporting offspring (age < 18 years) cardiac function by echocardiography compared between any type of diabetes in pregnancy and healthy control pregnancies were included. Study selection, quality assessment and risk of bias was independently performed by two reviewers. Meta-analyses was performed where possible. Results Thirty-one observational studies were included 1,679 cases and 2,694 controls. In the first week of life (23 studies, n = 2,663), intraventricular septum diastolic diameter (hypertrophy) was increased, while myocardial performance index (global function) and LV E/A-ratio (diastolic function) were decreased. No difference was found for left ventricular ejection fraction (systolic function). At 1-6 months (4 studies, n = 454) studies found hypertrophy, and decreased global function, but no difference in systolic or diastolic function. At 1-8 years (7 studies, n = 1,609) no difference was found. The available data did not allow for sub-analysis based on the type of diabetes, treatment, or glycemic control. Conclusions Diabetes in pregnancy is associated with cardiac hypertrophy and impaired global cardiac function in infants up to six months old. The few studies reporting on older children found no difference in the parameters investigated. Longitudinal studies employing more advanced echocardiographic measures or MRI are needed to evaluate consequences for long-term cardiac health.

Abstract
Gestational diabetes mellitus (GDM) and maternal obesity (MO) increase the risk of adverse fetal outcomes, and the incidence of cardiovascular disease later in life. Extensive research has been conducted to elucidate the underlying mechanisms by which GDM and MO program the offspring to disease. This review focuses on the role of fetoplacental endothelial dysfunction in programming the offspring for cardiovascular disease in GDM and MO pregnancies. We discuss how pre-existing maternal health conditions can lead to vascular dysfunction in the fetoplacental unit and the fetus. We also examine the role of fetoplacental endothelial dysfunction in impairing fetal cardiovascular system development and the involvement of nitric oxide and hydrogen sulfide in mediating fetoplacental vascular dysfunction. Furthermore, we suggest that the L-Arginine-Nitric Oxide and the Adenosine-L-Arginine-Nitric Oxide (ALANO) signaling pathways are pertinent targets for research. Despite significant progress in this area, there are still knowledge gaps that need to be addressed in future research.

Abstract
Importance Fetuses in women with gestational diabetes (GD) compared with those without GD show evidence of subclinical cardiac functional and morphological changes. However, it is uncertain whether glycemia or the adverse maternal underlying risk factor profile is the main driver for fetal cardiac remodeling. Objective To assess cardiac morphology and function at midgestation in fetuses of mothers prior to development of GD and compare them with those of unaffected controls. Design, Setting, and Participants During this prospective nonintervention screening study at 19 to 23 weeks' gestation, fetal cardiac morphology and function were assessed in all participants. Pregnancy complications were obtained from the medical records of the women. Fetal cardiac morphology and function were assessed in all participants at Harris Birthright Research Institute at King's College Hospital, London, United Kingdom. Participants included pregnant women with singleton pregnancy who attended their routine fetal ultrasound examination at midgestation and agreed to participate in the Advanced Cardiovascular Imaging Study in pregnancy. Main Outcome and Measures Comparison of fetal cardiac morphology and function between mothers who subsequently developed GD and those who did not develop GD. Methods This was a prospective nonintervention screening study of 5620 women with singleton pregnancies at 19 to 23 weeks' gestation. Conventional and more advanced echocardiographic modalities, such as speckle tracking, were used to assess fetal cardiac function in the right and left ventricle. The morphology of the fetal heart was assessed by calculating the right and left sphericity index. Results The 5620 included patients had a mean age of 33.6 years. In 470 cases, the women were diagnosed with GD after the midgestation echocardiographic assessment (8.4%). Women with GD, compared with the non-GD group, were older, had higher BMI, higher prevalence of family history of diabetes, non-White ethnicity, chronic hypertension, and GD in a previous pregnancy. In fetuses of the GD group compared with the non-GD group, there was mild increase in interventricular millimeter thickness (0.04; 95% CI, 0.03-0.06 mm) and left atrial area (0.04; 95% CI, 0.04-0.05), whereas left and right functional indices were comparable between groups with the exception of left ventricular ejection fraction, which was marginally improved in the GD group (0.02; 95% CI, 0.03-0.03). Conclusions and Relevance This study demonstrates that prior to development of GD, there was mild alteration in fetal cardiac morphology without affecting cardiac function. This suggests that the adverse maternal risk factor profile and not only the glycemia might contribute to cardiac remodeling noted in fetuses of women with GD.

Abstract
Pregnancy involves a range of metabolic adaptations to supply adequate energy for fetal growth and development. Gestational diabetes (GDM) is defined as hyperglycemia with first onset during pregnancy. GDM is a recognized risk factor for both pregnancy complications and long-term maternal and offspring risk of cardiometabolic disease development. While pregnancy changes maternal metabolism, GDM can be viewed as a maladaptation by maternal systems to pregnancy, which may include mechanisms such as insufficient insulin secretion, dysregulated hepatic glucose output, mitochondrial dysfunction and lipotoxicity. Adiponectin is an adipose-tissue-derived adipokine that circulates in the body and regulates a diverse range of physiologic mechanisms including energy metabolism and insulin sensitivity. In pregnant women, circulating adiponectin levels decrease correspondingly with insulin sensitivity, and adiponectin levels are low in GDM. In this review, we summarize the current state of knowledge about metabolic adaptations to pregnancy and the role of adiponectin in these processes, with a focus on GDM. Recent studies from rodent model systems have clarified that adiponectin deficiency during pregnancy contributes to GDM development. The upregulation of adiponectin alleviates hyperglycemia in pregnant mice, although much remains to be understood for adiponectin to be utilized clinically for GDM.

Abstract
BACKGROUND AND AIMS Certain exposures and risk factors during the first 1,000 days of life are known to influence future cardiovascular disease (CVD) risk. Pulse wave velocity (PWV) is a measure of arterial stiffness and a recognised surrogate marker of CVD. We performed a systematic review and meta-analyses to investigate whether early life exposures were associated with increased PWV compared with controls in youth. METHODS Databases AMED, MEDLINE, EMBASE, CINAHL and Scopus were searched from inception until February 2022. ELIGIBILITY CRITERIA observational controlled studies in youth aged <20 years with risk factors/exposure during the first 1,000 days and PWV measurement. This review is registered with PROSPERO (CRD42019137559). Outcome data were pooled using random-effects meta-analysis. Meta-regression was used to investigate potential confounders. RESULTS We identified 24 eligible studies. Age of participants ranged from 1-day to 19-years at time of PWV assessment. Exposures included pre-term birth, small for gestational age (SGA), maternal diabetes and assisted reproductive technologies, none of which were significantly associated with PWV in meta-analysis. Sub-group analysis by age demonstrated increased PWV in childhood and adolescence in those exposed to maternal diabetes or born SGA. In meta-regression of pre-term studies, higher prevalence of SGA was associated with increased PWV compared with controls (p = 0.034, R2 = 1). CONCLUSIONS We found limited evidence that youth exposed to maternal diabetes or born SGA have increased PWV, consistent with increased future CVD risk. These changes in PWV appear to manifest in later childhood and adolescence. Further research is required to better understand the observed relationships.

Abstract
OBJECTIVE To assess the association between hypertrophic cardiomyopathy (HCM) and mortality among infants of diabetic mothers (IDMs). METHODS We performed a retrospective cohort study of hospitalized IDMs admitted at ≤14-days-old in the Pediatric Health Information System (years 2004 - 2019). Multivariable logistic regression was used to evaluate the association between HCM and mortality; covariates in the model were prematurity, sex, and congenital malformations of the cardiovascular, nervous, urinary and musculoskeletal systems. RESULTS Among 32,993 IDMs, there were 203 (0.6%) with HCM. Black and Hispanic children were disproportionately represented among children with HCM compared to those without HCM (23.2 vs. 14.9%, p = .001 for Black, and 30.0 vs. 22.1%, p = .007 for Hispanic). IDMs with HCM were also larger at birth (median birth weight 4120 g [interquartile range 3600-4703] vs. 3270 g [interquartile range 2535-3910]; p < .001). In-hospital mortality in patients with HCM was greater than in those without HCM (4.9 vs. 1.3%, p < 0.001), and odds of mortality were greater among those with HCM (adjusted odds ratio 2.10, 95% confidence interval: 1.04-4.25; p = .038). CONCLUSION We identify HCM as a contributor to in-hospital mortality. These data reinforce the need for more specific diagnostic criteria, better prevention of maternal diabetes, and effective therapies for HCM in IDMs.

Abstract
Globally, cardiovascular disease remains the leading cause of death. Most concerning is the rise in cardiovascular risk factors including obesity, diabetes and hypertension among youth, which increases the likelihood of the development of earlier and more severe cardiovascular disease. While lifestyle factors are involved in these trends, an increasing body of evidence implicates environmental exposures in early life on health outcomes in adulthood. Maternal obesity and diabetes during pregnancy, which have increased dramatically in recent years, also have profound effects on fetal growth and development. Mounting evidence is emerging that maternal obesity and diabetes during pregnancy have lifelong effects on cardiovascular risk factors and heart disease development. However, the mechanisms responsible for these observations are unknown. In this review, we summarize the findings of recent experimental studies, showing that maternal obesity and diabetes during pregnancy affect energy metabolism and heart disease development in the offspring, with a focus on the mechanisms involved. We also evaluate early proof-of-concept studies for interventions that could mitigate maternal obesity and gestational diabetes-induced cardiovascular disease risk in the offspring.

Abstract
Maternal diabetes is a prevalent pathology that increases the risk of cardiovascular diseases in the offspring, the heart being one of the main target organs affected from the fetal stage until the adult life. Metabolic, pro-oxidant, and proinflammatory alterations in the fetal heart constitute the first steps in the adverse fetal programming of cardiovascular disease in the context of maternal diabetes. This review discusses both human and experimental studies addressing putative mechanisms involved in this fetal programming of heart damage in maternal diabetes. These include cardiac epigenetic changes, alterations in cardiac carbohydrate and lipid metabolism, damaging effects caused by a pro-oxidant and proinflammatory environment, alterations in the cardiac extracellular matrix remodeling, and specific signaling pathways. Putative actions to prevent cardiovascular impairments in the offspring of mothers with diabetes are also discussed.

Abstract
Survivors of extremely preterm birth (gestational age < 27 weeks) have been reported to exhibit an altered cardiovascular phenotype in childhood. The mechanisms are unknown. We investigated associations between postnatal nutritional intakes and hyperglycemia, and left heart and aortic dimensions in children born extremely preterm. Postnatal nutritional data and echocardiographic dimensions at 6.5 years of age were extracted from a sub-cohort of the Extremely Preterm Infants in Sweden Study (EXPRESS; children born extremely preterm between 2004-2007, n = 171, mean (SD) birth weight = 784 (165) grams). Associations between macronutrient intakes or number of days with hyperglycemia (blood glucose > 8 mmol/L) in the neonatal period (exposure) and left heart and aortic dimensions at follow-up (outcome) were investigated. Neonatal protein intake was not associated with the outcomes, whereas higher lipid intake was significantly associated with larger aortic root diameter (B = 0.040, p = 0.009). Higher neonatal carbohydrate intake was associated with smaller aorta annulus diameter (B = -0.016, p = 0.008). Longer exposure to neonatal hyperglycemia was associated with increased thickness of the left ventricular posterior wall (B = 0.004, p = 0.008) and interventricular septum (B = 0.004, p = 0.010). The findings in this study indicate that postnatal nutrition and hyperglycemia may play a role in some but not all long-lasting developmental adaptations of the cardiovascular system in children born extremely preterm.
