Abstract
Gestational diabetes mellitus (GDM) is well known to be associated with fetal overgrowth and short- or long-term adverse outcomes in singleton pregnancies; however, its relationship with twin pregnancies remains controversial, posing challenges for clinical management. Despite the heterogeneity in GDM diagnosis and racial differences among populations, two critical issues remain unaddressed. The first issue is methodological, specifically whether data on twins have been analyzed using appropriate approaches. The second issue is the underlying pathophysiology'. Given that both glucose demand and insulin resistance are elevated in twin pregnancies, the optimal level of maternal insulin secretion remains uncertain. In this paper, we summarize the current knowledge on GDM in the context of twin pregnancies, their perinatal outcomes, glucose control, and gestational weight gain management. We then propose methodological considerations for future improvements. Ultimately, we underscore the importance of delving into the glucose requirements of twin pregnancies to gain a profound understanding of their gestational glucose and insulin metabolism. All these questions are key issues in this area, and by answering them we will accelerate the development of high-quality, evidence-based clinical guidelines for GDM management in twin pregnancies.

Abstract
Diabetes and twin pregnancies are known risk factors for poor perinatal and neonatal outcomes. However, the effects of these two entities occurring together are still unclear. PubMed, Scopus and Google Scholar databases were searched in a systematic manner to identify observational studies among twin pregnancies, which documented the association of gestational diabetes with maternal and neonatal outcomes. All the analysis was done using STATA software. The meta-analysis included 21 studies, of which majority were retrospective data based. Mothers with gestational diabetes had higher risks of hypertensive disorder in pregnancy, caesarean section, large for gestational age baby, NICU admission and neonatal hypoglycaemia compared to mothers without gestational diabetes. Diabetic mothers were at reduced risk of small for gestational age baby and low APGAR score. No statistically significant differences in the risk of low birth weight, mean birth weight, prematurity and neonatal death were noted. This meta-analysis observed increased risks of detrimental maternal, neonatal and perinatal outcomes in twin pregnancies complicated by gestational diabetes, underscoring the need for the early detection and management of gestational diabetes.

Am J Obstet Gynecol 2021; 225:420.e1-420.e13. [PMID: 33872592 DOI: 10.1016/j.ajog.2021.04.225] [Citation(s) in RCA: 19] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Revised: 03/11/2021] [Accepted: 04/09/2021] [Indexed: 01/11/2023]
Abstract
BACKGROUND Gestational diabetes mellitus is associated with accelerated fetal growth in singleton pregnancies but may affect twin pregnancies differently because of the slower growth of twin fetuses during the third trimester of pregnancy and their greater predisposition to fetal growth restriction. OBJECTIVE This study aimed to evaluate the association of gestational diabetes mellitus with longitudinal fetal growth in twin pregnancies and to compare this association with that observed in singleton pregnancies. STUDY DESIGN This was a retrospective cohort study of all women with a singleton or twin pregnancy who were followed up at a single tertiary referral center between January 2011 and April 2020. Data on estimated fetal weight and individual fetal biometric indices were extracted from ultrasound examinations of eligible women. Generalized linear models were used to model and compare the change in fetal weight and individual biometric indices as a function of gestational age between women with and without gestational diabetes mellitus in twin pregnancies and between women with and without gestational diabetes mellitus in singleton pregnancies. The primary outcome was estimated fetal weight as a function of gestational age. The secondary outcomes were longitudinal growth of individual fetal biometric indices and the rate of small for gestational age and large for gestational age at birth. RESULTS A total of 26,651 women (94,437 ultrasound examinations) were included in the analysis: 1881 with a twin pregnancy and 24,770 with a singleton pregnancy. The rate of gestational diabetes mellitus in the twin and singleton groups was 9.6% (n=180) and 7.6% (n=1893), respectively. The estimated fetal weight in singleton pregnancies with gestational diabetes mellitus was significantly higher than that in pregnancies without gestational diabetes mellitus (P<.001) starting at approximately 30 weeks of gestation. The differences remained similar after adjusting for maternal age, chronic hypertension, nulliparity, and neonatal sex (P<.001). In twin pregnancies, fetal growth was similar between pregnancies with and without gestational diabetes mellitus (P=.105 and P=.483 for unadjusted and adjusted models, respectively). The findings were similar to the association of gestational diabetes mellitus with the risk of large for gestational fetuses and the growth of each biometric index. When stratified by type of gestational diabetes mellitus treatment, twin pregnancies with gestational diabetes mellitus was associated with accelerated fetal growth only in the subgroup of women with medically treated gestational diabetes mellitus (P<.001), which represented 12% (n=21) of the twin pregnancy group with gestational diabetes mellitus. CONCLUSION In contrast to singleton pregnancies, twin pregnancies with gestational diabetes mellitus is less likely to be associated with accelerated fetal growth. This finding has raised the question of whether the diagnostic criteria for gestational diabetes mellitus and the blood glucose targets in women diagnosed with gestational diabetes mellitus should be individualized for twin pregnancies.

Abstract
INTRODUCTION In singleton pregnancies, maternal complications, such as preeclampsia and thyroid dysfunction are associated with small for gestational age (SGA). However, data on the association between SGA and maternal complications in twin pregnancies are limited and conflicting. Small sample size and the application of singleton birth weight reference (SBWR) to define SGA in twins may be reasons for the inconsistent conclusions. Purpose of this study was to define SGA in dichorionic diamniotic (DCDA) and monochorionic diamniotic (MCDA) twin pregnancies using both SBWR and twin birth weight reference (TBWR) and to determine whether certain maternal complications are associated with SGA in twin pregnancies. MATERIALS AND METHODS This retrospective cohort study included all twins delivered in a single tertiary center between 2013 and 2018. SGA was defined as a twin with birth weight <10th centile for gestational age using either SBWR or TBWR. The association between SGA and maternal complications was analyzed separately for DCDA and MCDA twin pregnancies, expressed as odds ratio (OR) and adjusted odds ratio (aOR) with 95% confidence interval (95%-CI). RESULTS A total of 2005 DCDA and 467 MCDA twin pregnancies were enrolled. In DCDA pregnancies, SGA was significantly associated with PE according to TBWR (22.73 vs. 14.56%, aOR 1.823, 95%-CI 1.137-2.922). This association was even more pronounced between SGA and severe PE (9.09 vs. 4.54%, aOR 2.234, 95%-CI 1.115-4.479). In turn, PE was associated with higher risk of SGA defined according to TBWR (8.31 vs. 4.99%, aOR 1.825, 95%-CI 1.139-2.925). No association was detected between SGA and other maternal complications. Using SBWR, no association was found between preeclampsia and SGA. In MCDA pregnancies, according to TBWR, SGA was associated only with severe PE (12.5 vs. 4.06%, aOR 3.470, 95%-CI 1.256-9.587) and lower risk of PROM (aOR 0.067, 95%-CI 0.014-0.322). CONCLUSION PE was associated with SGA in DCDA pregnancies only when TBWR was used, suggesting that DCDA pregnancies complicated with PE should be closely monitored for signs of SGA and vice versa. In MCDA pregnancies, SGA defined according to TBWR was associated with only severe PE (but not with all PE) and lower risk of PROM. More basic experiments are needed to investigate the mechanisms underlying PE and SGA in DCDA and MCDA twin pregnancies respectively.

Abstract
AIMS/INTRODUCTION The association between gestational diabetes mellitus (GDM) and adverse maternal and perinatal outcomes in twin pregnancies remains unclear. This study was undertaken to highlight risk factors for GDM in women with dichorionic (DC) twins, and to determine the association between GDM DC twins and adverse maternal and perinatal outcomes in a large homogeneous Taiwanese population. MATERIALS AND METHODS A retrospective cross-sectional study was carried out on 645 women with DC twins, excluding pregnancies complicated by one or both fetuses with demise (n = 22) or congenital anomalies (n = 9), who gave birth after 28 complete gestational weeks between 1 January 2001 and 31 December 2018. Univariable and multiple logistic regression analyses were carried out. RESULTS Maternal age >34 years (adjusted odds ratio 2.52; 95% confidence interval 1.25-5.07) and pre-pregnancy body mass index >24.9 kg/m2 (adjusted odds ratio 2.83, 95% confidence interval 1.47-5.46) were independent risk factors for GDM in women with DC twins. Newborns from women with GDM DC twins were more likely to be admitted to the neonatal intensive care unit (adjusted odds ratio 1.70, 95% confidence interval 1.06-2.72) than newborns from women with non-GDM DC twins. Other pregnancy and neonatal outcomes were similar between the two groups. CONCLUSIONS Advanced maternal age and pre-pregnancy overweight or obesity are risk factors for GDM in women with DC twins. Except for a nearly twofold increased risk of neonatal intensive care unit admission of newborns, the pregnancy and neonatal outcomes for women with GDM DC twins are similar to those for women with non-GDM DC twins.

Abstract
AbstractIt has been suggested that the risk of adverse perinatal outcomes in twin pregnancies is exacerbated by concomitant gestational diabetes mellitus (GDM). This study aimed to assess the risk incurred by twin pregnancy and by a diagnosis of GDM, separately, on the development of poor perinatal outcomes. A retrospective cohort study was conducted on all pregnant women at a tertiary center between 2016 and 2017. The impact of GDM and twin pregnancies on perinatal outcomes — birth weight above the 90th centile for gestational age, cesarean delivery, clinical neonatal hypoglycemia, and premature delivery (before 37 weeks’ gestation) — was assessed using univariate and multivariate analyses. Overall, 13,527 women were eligible for the study; 11,915 were uncomplicated singleton pregnancies; 1379 of these had GDM; 194 were twin pregnancies, and 39 of these had GDM. Univariate analyses showed that twin pregnancies were associated with a higher risk of all perinatal outcomes except macrosomia. In the multivariate analyses, twin pregnancy was a much higher predictor of cesarean delivery (OR 8.40, 95% CI [6.25, 11.49], p < .0001) and preterm birth (OR 58.82, 95% CI [31.25, 125], p < .0001) compared to GDM but GDM was a higher predictor of neonatal hypoglycemia (OR 4.87, 95% CI [3.74, 6.29], p < .0001). Twin pregnancy is more strongly associated with all adverse perinatal outcomes except macrosomia. GDM does not increase risk of adverse perinatal outcomes except for neonatal hypoglycemia.

Abstract
OBJECTIVE Gestational diabetes mellitus (GDM) in singleton pregnancy is associated with large for gestational age neonates and adverse perinatal outcomes; however, the impact of GDM in twin pregnancy is unclear. Thus, the aim of this study is to assess the perinatal outcomes of twin pregnancies complicated by GDM by performing a meta-analysis of observational studies. STUDY DESIGN Studies investigating GDM in twin pregnancy were identified through an online search of three databases: Medline, Embase and Web of Science. Selection criteria comprised full paper observational studies (retrospective or prospective) published in English that examined GDM in twin pregnancy compared with non-GDM twin pregnancy and reported on birth weight and/or adverse perinatal outcomes. Random-effects models with inverse-variance weighting were used to calculate standardized mean differences and unadjusted odds ratios. Sensitivity analyses were carried out to determine the impact of possible maternal confounders (body mass index and age) and GDM diagnostic criteria on perinatal outcomes. RESULTS Thirteen observational studies were included. GDM twins were born at the same gestation as non-GDM twins, with marginally lower birth weight. There was no difference in the incidence of large or small for gestational age neonates. Although there was no correlation between GDM in twin pregnancy and respiratory distress, neonatal hypoglycemic or low Apgar score, GDM twins had a higher rate of neonatal intensive care unit admission (OR 1.49; 95% confidence interval: 1.10, 2.02; P<0.01). CONCLUSION Identification and subsequent treatment of GDM in twin pregnancy demonstrates a similar risk of adverse perinatal outcomes compared with non-GDM twin pregnancies.

Abstract
BACKGROUND Women with twin pregnancies are at increased risk for fetal growth restriction, which might be attributed to the limited maternal resources that are being shared by >1 fetus. Based on that, it may be hypothesized that the fetal effects of gestational diabetes mellitus (GDM) with respect to accelerated fetal growth may be less pronounced in twin gestations or alternatively may even have a beneficial role in decreasing the risk of fetal growth restriction in these pregnancies. However, available data are conflicting and are limited by the fact that many of the complications associated with GDM are less relevant for twin gestations, and that all women with GDM included in previous studies were monitored and treated to control maternal blood glucose levels. OBJECTIVE We sought to assess the impact of GDM and milder degrees of glucose intolerance on fetal growth and pregnancy outcome in twin pregnancies. STUDY DESIGN This was a retrospective cohort study of all women with twin pregnancies who underwent screening for GDM in a single tertiary referral center from October 2003 through December 2014. The diagnosis of GDM during the study period was based on the 2008 Canadian Diabetes Association (CDA) guidelines, which involve universal screening with a 50-g glucose challenge test (GCT) followed by a diagnostic 2-hour 75-g oral glucose tolerance test (OGTT). Fetal growth and pregnancy outcome were compared among 4 groups of women with increasing degree of glucose intolerance: (1) GCT-NEGATIVE, negative 50-g GCT; (2) OGTT-NEGATIVE, positive 50-g GCT followed by a negative 75-g OGTT; (3) GDM-IADPSG, positive 50-g GCT followed by a positive 75-g OGTT according to the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) criteria but not the 2008 CDA criteria-because these women were not considered to have GDM during the study period they were not subjected to any form of treatment; and (4) GDM-CDA, positive 50-g GCT followed by a positive 75-g OGTT according to the 2008 CDA criteria. RESULTS Overall 1393 women were eligible for the study: 1021 (73.3%) in the GCT-NEGATIVE group, 184 (13.2%) in the OGTT-NEGATIVE group, 99 (7.1%) in the GDM-IADPSG group, and 89 (6.4%) in the GDM-CDA group. There was a continuous relationship between the degree of glucose intolerance and fetal growth as reflected by a right shift of the distribution curve of birthweight percentiles and a greater likelihood of high birthweight percentile: OGTT-NEGATIVE = odds ratio (OR), 1.5; 95% confidence interval (CI), 1.07-2.2; GDM-IADPSG = OR, 1.7; 95% CI, 1.1-2.6; and GDM-CDA = OR, 1.9, 95% CI, 1.3-3.1 (using the GCT-NEGATIVE group as reference). Fetuses of women with glucose intolerance were more likely to experience asymmetric growth as reflected by an elevated abdominal circumference to head circumference ratio. CONCLUSION GDM and milder degrees of glucose intolerance in twin pregnancies are associated with an increased risk of asymmetric overgrowth in a manner that is related to the degree of glucose intolerance.

Abstract
AIMS To evaluate the influence of gestational diabetes mellitus on neonatal birthweight, macrosomia and weight discrepancy in twin neonates. METHODS An observational retrospective study was performed. One hundred and six women with gestational diabetes and twin pregnancy and 166 twin controls who delivered viable fetuses > 24 weeks were included. Impact of maternal pre-pregnancy BMI, smoking habit, method of conception, chorionicity, gestational age at delivery, mode of delivery and hypertensive complications were also analysed. The effect of maternal hyperglycaemia and metabolic control in gestational diabetes pregnancies was assessed. RESULTS Gestational hypertension and pre-eclampsia were significantly higher in the group with gestational diabetes (21.5% vs. 6.3%, P = 0.007 and 6.2% vs. 0%, P = 0.025). There were no differences in the incidence of macrosomia (5.7% vs. 7.2%, P = 0.803), large for gestational age (10.3% vs. 13.2%, P = 0.570), small for gestational age (10.3% vs. 12.0%, P = 0.701), severely small for gestational age (6.6% vs. 7.8%, P = 0.814) or weight discrepancy (20.6% vs. 15.2%, P = 0.320) in the group with gestational diabetes compared with twin pregnancies without diabetes. There were no differences when comparing insulin-requiring gestational diabetes pregnancies and twins without diabetes for any of the neonatal weight outcomes. There was no relationship between third trimester HbA1c and neonatal birthweight or infant birthweight ratio. CONCLUSION Gestational diabetes did not increase the risk of macrosomia or weight discrepancy of twin newborns. Furthermore, glycaemic control did not influence the rate of any of the weight outcomes in our study population. In twin pregnancies, gestational diabetes was associated with a higher risk of gestational hypertension and pre-eclampsia.

Abstract
OBJECTIVE To compare outcomes of twin pregnancies with and without gestational diabetes mellitus (GDM). STUDY DESIGN We compared 105 twin pregnancies with GDM (7.8% of all twin pregnancies) to 315 controls without GDM, matched for gestational age, chorionicity and year of birth. RESULTS Pre-gravid obesity appears to predispose women to GDM during twin pregnancy [odds ratio (OR) 3.5; 95% confidence interval (CI) 1.7, 7.0]. Overweight and obese women that subsequently developed GDM during their twin gestation were less likely to conceive spontaneously (OR 0.4; 95% CI 0.3, 0.7). Twins from the GDM group had more respiratory distress syndrome (RDS, OR 2.2; 95% CI 1.3, 3.7) and had a three-fold, but not significantly increased perinatal mortality rate. Birth weight characteristics were similar in both groups. CONCLUSION Twin pregnancies complicated by GDM might be associated with pre-pregnancy maternal obesity and are at increased risk of RDS and non-significant increased risk of perinatal death.
