Full Text Available OBJECTIVE: To assess the efficacy and safety of oral antidiabetic drugs (OADs in gestational diabetes mellitus (GDM in comparison to insulin. METHODS: A meta-analysis of randomized controlled trials was conducted. The efficacy and safety of OADs in comparison to insulin in GDM patients were explored. Studies were identified by conducting a literature search using the electronic databases of Medline, CENTRAL, CINAHL, LILACS, Scopus and Web of Science in addition to conducting hand search of relevant journals from inception until October 2013. RESULTS: Thirteen studies involving 2,151 patients met the inclusion criteria. These studies were randomized controlled trials of metformin and glyburide in comparison to insulin therapy. Our results indicated a significant increase in the risk for preterm births (RR, 1.51; 95% CI, 1.04-2.19, p = 0.03 with metformin compared to insulin. However, a significant decrease in the risk for gestational hypertension (RR, 0.54; 95% CI, 0.31-0.91, p = 0.02 was found. Postprandial glucose levels also decreased significantly in patients receiving metformin (MD, -2.47 mg/dL; 95% CI, -4.00, -0.94, p = 0.002. There was no significant difference between the two groups for the remaining outcomes. There were significant increases in the risks of macrosomia (RR, 2.34; 95% CI, 1.18-4.63, p = 0.03 and neonatal hypoglycemia (RR, 2.06; 95% CI, 1.27-3.34, p = 0.005 in the glyburide group compared to insulin whereas results for the other analyzed outcomes remained non-significant. CONCLUSION: The available evidence suggests favorable effects of metformin in treating GDM patients. Metformin seems to be an efficacious alternative to insulin and a better choice than glyburide especially those with mild form of disease.

The presence of injection related anxiety and phobia may influence compliance, glycaemic control and quality of life in patients with insulin-treated diabetes. Unselected consecutive, insulin-treated patients attending a diabetes clinic for follow-up, completed a standardised questionnaire providing an injection anxiety score (IAS) and general anxiety score (GAS). A total of 115 insulin-treated (80 Type 1 and 35 Type 2) diabetic patients completed the questionnaire. Injections had been avoided secondary to anxiety in 14% of cases and 42% expressed concern at having to inject more frequently. An IAS > or = 3 was seen in 28% of patients and of these, 66% injected insulin one to two times/day, 45% had avoided injections, and 70% would be bothered by more frequent injections. A significant correlation between IAS and GAS was seen (Kendall's tau-a 0.30, 95% CI 0.19-0.41, P < 0.001). GAS was significantly associated with both previous injection avoidance and expressed concern at increased injection frequency. No significant correlation was seen with HbA1c and injection or general anxiety scores. Symptoms relating to insulin injection anxiety and phobia have a high prevalence in an unselected group of diabetic patients requiring insulin injections and are associated with higher levels of general anxiety.

To determine if metformin monotherapy or metformin in combination with insulin is equally effective as insulin monotherapy at glycemic control in diabetes mellitus in pregnancy among Ghanaians. This was a study involving 104 pregnant women with type 2 diabetes mellitus (T2DM) or gestational diabetes mellitus (GDM) at 20-30 weeks gestation. Participants were randomized into metformin and insulin treatment groups. Starting dose of metformin was 500 mg once a day and increased gradually over two (2) weeks, to meet glycemic targets. Insulin was added if targets could not be reached on metformin alone at maximum doses. Total daily dose of premixed insulin at initiation was calculated as 0.3 IU/kg body weight and titrated upwards to achieve glycemic control. Glycemic profile monitoring was done every two weeks. The two hour post prandial blood glucose (2HPG) levels were significantly lower in the metformin group than the insulin group (p= 0.004). The findings of this study suggest that metformin monotherapy is effective in achieving glycemic targets in the management of diabetes in pregnancy. It is more effective than insulin in lowering the 2HPG level. Australian New Zealand Clinical Trials Registry (ANZCTR) ACTRN12614000942651.

The aim of the study is to compare the effects of metformin and insulin treatment for gestational diabetes mellitus (GDM) on vitamin B12 and homocysteine (Hcy) status. Women with GDM, who met criteria for insulin treatment, were randomly assigned to metformin (n = 89) or insulin (n = 91) in the Adelaide cohort of the metformin in gestational diabetes (MiG) trial. Fasting serum total vitamin B12 (TB12), holotranscobalamin (HoloTC), a marker of functional B12 status and plasma Hcy concentrations were measured at 20-34 weeks (at randomization) and 36 weeks gestation, then at 6-8 weeks postpartum. Circulating TB12, HoloTC and Hcy were similar in both treatment groups at each time point. Women who were taking dietary folate supplements at randomization had higher serum TB12 and HoloTC at randomization than those not taking folate. Overall, serum TB12 fell more between randomization and 36 weeks gestation in the metformin group than in the insulin group (metformin: -19.7 ± 4.7 pmol/l, insulin: -6.4 ± 3.6 pmol/l, p = 0.004). The decrease in serum TB12 during treatment was greater with increasing treatment duration in metformin-treated (p pregnancy to a greater extent in metformin-treated than in insulin-treated women with GDM, but neither analyte differed between groups at any stage. This adds further evidence supporting metformin as a safe alternative treatment to insulin in GDM. Further investigation is needed to evaluate whether women treated with metformin for longer periods in pregnancy require additional B12 or other supplementation. © 2013 Blackwell Publishing Ltd.

Full Text Available Metformin is increasingly being used a therapeutic option for the management of gestational diabetes mellitus (GDM. The aim of this study was to compare the maternal characteristics and perinatal outcomes of women with GDM treated with metformin (with or without supplemental insulin with those receiving other management approaches. A retrospective, case-control study was carried out and 83 women taking metformin were matched 1:1 with women receiving insulin or diet and lifestyle modification alone. Women managed with diet and lifestyle modification had a significantly lower fasting plasma glucose (p < 0.001 and HbA1c (p < 0.01 at diagnosis of GDM. Furthermore, women managed with metformin had a higher early pregnancy body mass index (BMI compared to those receiving insulin or diet and lifestyle modification (p < 0.001. There was no difference in mode of delivery, birth weight or incidence of large- or small-for-gestational-age neonates between groups. Women receiving glucose lowering therapies had a higher rate of neonatal hypoglycaemia (p < 0.05. The incidence of other adverse perinatal outcomes was similar between groups. Despite their greater BMI, women with metformin-treated GDM did not have an increased risk of adverse perinatal outcomes. Metformin is a useful alternative to insulin in the management of GDM.

2016-12-01

Gestational diabetes mellitus (GDM) has affected a great number of pregnant women worldwide. Artemisia extracts have been found to exhibit a potent antidiabetic effect in the treatment of type 2 diabetes mellitus. We aimed to examine the effects of Artemisia extract on insulin resistance and lipid profiles in pregnant GDM patients. Patients in their second trimester were randomly assigned to the Artemisia extract group (AE) or to a placebo group (PO). They were instructed to consume either AE or PO daily for a period of 10 weeks. Glucose and insulin profiles and adiponectin level were assessed at baseline (week 0) and after the treatment (week 10). Compared to the PO group, fasting plasma glucose, serum insulin levels, homeostasis model of assessment of insulin resistance (HOMA-IR), and β-cell function (HOMA-B) were significantly reduced in the AE group participants. Moreover, levels of circulating adiponectin were also significantly up-regulated in the AE group, which also positively contributed to improved insulin sensitivity. Daily administration of Artemisia extract improves insulin sensitivity by up-regulating adiponectin in women with gestational diabetes mellitus. © 2016, The American College of Clinical Pharmacology.

Amanda L. da Silva

Full Text Available Abstract: Objectives: To compare different neonatal outcomes according to the different types of treatments used in the management of gestational diabetes mellitus. Methods: This was a retrospective cohort study. The study population comprised pregnant women with gestational diabetes treated at a public maternity hospital from July 2010 to August 2014. The study included women aged at least 18 years, with a singleton pregnancy, who met the criteria for gestational diabetes mellitus. Blood glucose levels, fetal abdominal circumference, body mass index and gestational age were considered for treatment decision-making. The evaluated neonatal outcomes were: type of delivery, prematurity, weight in relation to gestational age, Apgar at 1 and 5 min, and need for intensive care unit admission. Results: The sample consisted of 705 pregnant women. The neonatal outcomes were analyzed based on the treatment received. Women treated with metformin were less likely to have children who were small for gestational age (95% CI: 0.09-0.66 and more likely to have a newborn adequate for gestational age (95% CI: 1.12-3.94. Those women treated with insulin had a lower chance of having a preterm child (95% CI: 0.02-0.78. The combined treatment with insulin and metformin resulted in higher chance for a neonate to be born large for gestational age (95% CI: 1.14-11.15 and lower chance to be born preterm (95% CI: 0.01-0.71. The type of treatment did not affect the mode of delivery, Apgar score, and intensive care unit admission. Conclusions: The pediatrician in the delivery room can expect different outcomes for diabetic mothers based on the treatment received.

The aim was to compare the insulin sensitivity and secretion index of pregnant Korean women with normal glucose tolerance (NGT), gestational impaired glucose tolerance (GIGT; only one abnormal value according to the Carpenter and Coustan criteria), and gestational diabetes mellitus (GDM). A cross-sectional study was performed with 1,163 pregnant women with positive (1-hour plasma glucose ≥ 7.2 mmol/L) in a 50-g oral glucose challenge test (OGCT). The 100-g oral glucose tolerance test (OGTT) was used to stratify the participants into three groups: NGT (n = 588), GIGT (n = 294), and GDM (n = 281). The GDM group had higher homeostasis model assessment of insulin resistance and lower insulin sensitivity index (ISOGTT), quantitative insulin sensitivity check index, homeostasis model assessment for estimation of index β-cell secretion (HOMA-B), first and second phase insulin secretion, and insulin secretion-sensitivity index (ISSI) than the NGT group (p ≤ 0.001 for all). Moreover, the GIGT group had lower ISOGTT, HOMA-B, first and second phase insulin secretion, and ISSI than the NGT group (p insulin secretion status than the 3-hour abnormal levels group. Korean women with GDM show impairments of both insulin secretion and insulin sensitivity. In addition, GIGT is associated with both β-cell dysfunction and insulin resistance.

2014-09-01

The effects of soybean oligosaccharides (SBOS) on antioxidant enzyme activities and insulin resistance in pregnant women with gestational diabetes mellitus (GDM) were investigated. Ninety-seven pregnant women with GDM were randomly divided into two groups, the control group (51 cases) and the SBOS group (46 cases). Before the group separation, the blood sugar level in patients was maintained stable by regular diet and insulin treatment. The control group was continued with the insulin treatment, while the SBOS group was treated with the combination of insulin and SBOS. Results showed that SBOS were able to reduce oxidative stress and alleviate insulin resistance in pregnant women with GDM, which indicates that SBOS may play an important role in the control of GDM complications.

Gestational diabetes mellitus (GDM) is one of the common complications that occur during pregnancy. Early intervention is essential to prevent the development of the disease in the non-pregnant state but also helpful in preventing the occurrence of GDM. The aim of the study was to assess the effect of aerobic exercises on insulin sensitivity and fasting plasma glucose level in pregnant women with risk for gestational diabetes mellitus. Forty multigravidae women between 20-24 weeks of gestation with risk for GDM were randomly selected (age range was 25-35 years), body mass index ranged from 30-35 kg/m 2 . Women were divided into two equal groups: intervention group (A), which followed an aerobic exercise program in the form of walking on treadmill, three times weekly until the end of 37 weeks of gestation in addition to diet control. Control group (B) which received diet control with usual care given by obstetricians and midwives. Evaluation of the women in both groups was carried out before and after treatment program through assessment of fasting blood glucose and insulin levels. There was a highly statistically significance decrease in fasting blood glucose level, fasting insulin level in both groups where the p value was 0.0001 favoring group (A). Moderate intensity of aerobic exercises were effective in reducing fasting blood glucose level and fasting insulin level in pregnant women with risk for gestational diabetes mellitus.

To evaluate the effectiveness of metformin compared with insulin in achieving glycemic control and investigate the maternal and neonatal outcomes in gestational diabetes mellitus. We searched four electronic databases from inception through December 2012. Terms for Gestational diabetes/gestational diabetes mellitus/diabetes pregnancy AND/OR Metformin/hypoglycemic drugs/Hypoglycemic Agents/Antidiabetic Medications were used in the search. Two investigators independently reviewed titles and abstracts, performed data abstraction on full articles, and assessed study quality. Meanwhile, manual search of other resources and the search on Google Scholar were also carried out to identify more related articles .Rev Man 5.0 was used to analyze the data. Six randomized clinical trials involving 1420 subjects were included. The current limited data suggested that using metformin in gestational diabetes subjects did not significantly increase adverse maternal outcomes and neonatal outcomes, also with less weight gain and neonatal hypoglycemia, but a higher incidence of premature birth. Metformin will not increase the incidence of adverse maternal outcomes and neonatal outcomes. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

We investigated the impact of pregestationally elevated insulin plasma levels on glycemic control in pregnant women with polycystic ovary disease (PCOD). Twelve patients with PCOD who became pregnant within six months following evaluation of their metabolic status were the study subjects. Four were obese and six (two obese) had a hyperinsulinemic response to the oral glucose tolerance test (OGTT). They were tested with the OGTT at 28-30 weeks of gestation. We also tested 12 normal patients and 10 consecutive patients with gestational diabetes; all were at the same gestational age. Plasma levels of insulin and glucose were determined in the samples collected for a period of four hours after glucose load (100 g). All PCOD patients significantly increased their insulin secretion in pregnancy. The hyperinsulinemic PCOD patients developed gestational diabetes (two patients) and impaired gestational glucose tolerance (three patients). The area under the insulin curve was greater in PCOD patients than in control and gestational diabetes patients (P PCOD may develop a derangement of glycemic control, probably related to their pregestational insulinemic status.

Gestational diabetes mellitus is a condition commonly encountered during mid to late pregnancy with pathologic manifestations including hyperglycemia, hyperinsulinemia, insulin resistance, and fetal maldevelopment. The cause of gestational diabetes mellitus can be attributed to both genetic and environmental factors, hence complicating its diagnosis and treatment. Pancreatic progenitors derived from human embryonic stem cells were shown to be able to effectively treat diabetes in mice. In this study, we have developed a system of treating diabetes using human embryonic stem cell-derived pancreatic endoderm in a mouse model of gestational diabetes mellitus. Human embryonic stem cells were differentiated in vitro into pancreatic endoderm, which were then transplanted into db/+ mice suffering from gestational diabetes mellitus. The transplant greatly improved glucose metabolism and reproductive outcome of the females compared with the control groups. Our findings support the feasibility of using differentiated human embryonic stem cells for treating gestational diabetes mellitus patients. Copyright © 2015 Elsevier Inc. All rights reserved.

Metformin vs insulin in the management of gestational diabetes: a meta-analysis.

Full Text Available BACKGROUND: Nowadays, there have been increasing studies comparing metformin with insulin. But the use of metformin in pregnant women is still controversial, therefore, we aim to examine the efficiency and safety of metformin by conducting a meta-analysis of randomized controlled trials (RCTs comparing the effects of metformin with insulin on glycemic control, maternal and neonatal outcomes in gestational diabetes mellitus (GDM. METHODS: We used the key words "gestational diabetes" in combination with "metformin" and searched the databases including Pubmed, the Cochrane Library, Web of knowledge, and Clinical Trial Registries. A random-effects model was used to compute the summary risk estimates. RESULTS: Meta-analysis of 5 RCTs involving 1270 participants detected that average weight gains after enrollment were much lower in the metformin group (n = 1006, P = 0.003, SMD = -0.47, 95%CI [-0.77 to -0.16]; average gestational ages at delivery were significantly lower in the metformin group (n = 1270, P = 0.02, SMD = -0.14, 95%CI [-0.25 to -0.03]; incidence of preterm birth was significantly more in metformin group (n = 1110, P = 0.01, OR = 1.74, 95%CI [1.13 to 2.68]; the incidence of pregnancy induced hypertension was significantly less in the metformin group (n = 1110, P = 0.02, OR = 0.52, 95%CI [0.30 to 0.90]. The fasting blood sugar levels of OGTT were significantly lower in the metformin only group than in the supplemental insulin group (n = 478, P = 0.0006, SMD = -0.83, 95%CI [-1.31 to -0.36]. CONCLUSIONS: Metformin is comparable with insulin in glycemic control and neonatal outcomes. It might be more suitable for women with mild GDM. This meta-analysis also provides some significant benefits and risks of the use of metformin in GDM and help to inform further development of management guidelines.

Factors associated with increasing maternal triglyceride concentrations in late pregnancy include gestational age, obesity, preeclampsia, and altered glucose metabolism. In a subgroup of women in the Metformin in Gestational Diabetes (MiG) trial, maternal plasma triglycerides increased more between enrollment (30 weeks) and 36 weeks in those treated with metformin compared with insulin. The aim of this study was to explain this finding by examining factors potentially related to triglycerides in these women. Of the 733 women randomized to metformin or insulin in the MiG trial, 432 (219 metformin and 213 insulin) had fasting plasma triglycerides measured at enrollment and at 36 weeks. Factors associated with maternal triglycerides were assessed using general linear modeling. Mean plasma triglyceride concentrations were 2.43 (95% CI 2.35-2.51) mmol/L at enrollment. Triglycerides were higher at 36 weeks in women randomized to metformin (2.94 [2.80-3.08] mmol/L; +23.13% [18.72-27.53%]) than insulin (2.65 [2.54-2.77] mmol/L, P = 0.002; +14.36% [10.91-17.82%], P = 0.002). At 36 weeks, triglycerides were associated with HbA1c (P = 0.03), ethnicity (P = 0.001), and treatment allocation (P = 0.005). In insulin-treated women, 36-week triglycerides were associated with 36-week HbA1c (P = 0.02), and in metformin-treated women, they were related to ethnicity. At 36 weeks, maternal triglycerides were related to glucose control in women treated with insulin and ethnicity in women treated with metformin. Whether there are ethnicity-related dietary changes or differences in metformin response that alter the relationship between glucose control and triglycerides requires further study.

Gestational diabetes mellitus (GDM) is a metabolic disorder characterized by insulin resistance (IR) and altered glucose-lipid metabolism. We propose that ectonucleotide pyrophosphate phosphodiesterase-1 (ENPP1), a protein known to induce adipocyte IR, is a determinant of GDM. Our objective was to study ENPP1 expression in adipose tissue (AT) of obese pregnant women with or without GDM, as well as glucose tolerance in pregnant transgenic (Tg) mice with AT-specific overexpression of human ENPP1. AT biopsies and blood were collected from body mass index-matched obese pregnant women non-GDM (n = 6), GDM (n = 7), and nonpregnant controls (n = 6) undergoing cesarian section or elective surgeries, respectively. We measured the following: (1) Expression of key molecules involved in insulin signaling and glucose-lipid metabolism in AT; (2) Plasma glucose and insulin levels and calculation of homeostasis model assessment of IR (HOMA-IR); (3) Intraperitoneal glucose tolerance test in AtENPP1 Tg pregnant mice. We found that: (1) Obese GDM patients have higher AT ENPP1 expression than obese non-GDM patients, or controls (P = 0.01-ANOVA). (2) ENPP1 expression level correlated negatively with glucose transporter 4 (GLUT4) and positively with insulin receptor substrate-1 (IRS-1) serine phosphorylation, and to other adipocyte functional proteins involved in glucose and lipid metabolism (P Pregnant AT ENPP1 Tg mice showed higher plasma glucose than wild type animals (P = 0.046-t test on area under curve [AUC] glucose ). Our results provide evidence of a causative link between ENPP1 and alterations in insulin signaling, glucose uptake, and lipid metabolism in subcutaneous abdominal AT of GDM, which may mediate IR and hyperglycemia in GDM.

To evaluate the effect of probiotic supplements on insulin resistance in pregnant women with diet-controlled gestational diabetes mellitus. A randomized, double-blind, placebo-controlled trial was conducted between June 2016 and February 2017. Pregnant women with diet-controlled gestational diabetes mellitus were enrolled in the study at 24-28 weeks of gestation and randomized to receive either probiotic supplements containing Bifidobacterium and Lactobacillus or placebo daily for four consecutive weeks. Primary outcomes were mean differences in insulin resistance (HOMA-IR), fasting insulin and fasting plasma glucose between the two groups. Secondary outcomes were changes in maternal weight after the intervention. Data from 28 patients in the probiotic group and 29 in the placebo group were analyzed. The changes in metabolic parameters after randomization indicated significant improvement in glucose metabolism in the probiotic group compared to the placebo group, including fasting plasma glucose (0.68 ± 5.88 vs. 4.620 ± 7.78 mg/dL, mean difference, MD, -3.94 mg/dL (95% CI -7.62, -0.27), p-value 0.034), fasting plasma insulin (1.11 ± 1.71 vs. 3.77 ± 1.70 mIU/L, MD -2.67 mIU/L (95%CI -3.57, -1.76), p-value 0.001) and HOMA-IR (0.25 ± 0.37 vs. 0.89 ± 0.46, MD -0.63 (95% CI -0.86, -0.41), p-value 0.001). Weight gain during randomization was similar between the two groups. Four weeks of probiotic supplements in women with diet-controlled gestational diabetes in the late second- and early third-trimester lowered fasting glucose and increased insulin sensitivity. Probiotic supplements may be considered as an adjunct treatment for glycemic control in these patients. This article is protected by copyright. All rights reserved.

A total of 100 healthy pregnant women and 185 patients with GDM were available for examination. 80 patients developedGDM during current pregnancy, in 105 it was diagnosed 4-19 years ago. 25 of the 105 GDM patients had a history of type 2 DM. The following parameterswere measured: beta-cell secretory activity (proinsulin, ITI, C-peptide, total cholesterol (CH, HDL and LDL CH, triglycerides, HbA1c,fasting glycemia. Molecular-genetic DNA testing using PCR included studies of KCNJ 11, TCF7L2, PPARG2, ADIPOQ, ADIPOR1, ADIPOR2gene polymorphism. These genes were chosen based on the published data associating them with disturbed insulin secretion and sensitivity in DM2patient. Results. Pregnant women with GDM and obesity showed elevated IRI and leptin levels compared with controls. This rise was accompanied bymarked insulin resistance in 75% of these patients. In 50% of the healthy women proinsulin and insulin secretion decreased. Obesity in pregnantpatients was associated with significant elevation of proinsulin, IRI, and C-peptyide levels and GDM with Lys/Lys genotype of polymorphous markerGlu23k of KCNJ11 gene, pro and ala allele of polymorphous marker A219T of ADIPOR2 gene. These associations suggest specific genetic featuresof GDM related to impaired insulin secretion and sensitivity. Conclusion. Studies of common genetic nature of GDM and DM2 permit to identify risk groups at the preclinical stage, plan prevention and treatmentof these disorders.

Gestational diabetes mellitus is a common medical problem associated with maternal and fetal complications. Good glycemic control is the cornerstone of treatment. Compare outcomes between four times (q.i.d) and twice daily (b.i.d) regimens. The morning dose of the b.i.d regimen contained two-thirds of the total insulin, comprising a third human regular insulin and two-thirds human intermediate insulin; equal amounts in the evening. 480 women at >30 weeks with gestational diabetes mellitus with failure to control blood glucose were randomly assigned to either regimen. Mean time to the control of blood glucose was significantly less and glycemic control significantly increased with the q.i.d regimen. Operative deliveries, extent of neonatal hypoglycemia, babies with low Agpar scores and those with hyperbilirubinemia were significantly higher with the b.i.d daily regimen. The q.i.d daily regime was associated with improved fetal and maternal outcomes. Consequently should increasingly be used in Pakistan, assisted by lower acquisition costs.

The aim of this study was to evaluate adipokines concentration and insulin resistance according to maternal age or obesity at pregnancy and weight change at diagnosed gestational diabetes mellitus (GDM) in pregnant women with GDM. This study included 57 pregnant women who were diagnosed with GDM at 24 to 28 weeks of gestation. The subjects were classified into two or three groups according to pre-pregnancy body mass index (BMI, insulin resistance (HOMA-IR), and HOMA2-%B were increased in the group with pre-pregnancy BMI ≥25 kg/m². Leptin and HOMA-IR were positively correlated with BMI both before pregnancy and at screening for GDM. There were no significant correlations between HOMA-IR and adipokines. HOMA-IR showed positive correlation with HOMA2-%B and negative correlation with HOMA2-%S. Leptin and HOMA-IR at diagnosed GDM were increased in the GDM patients with obesity before pregnancy. They were positively correlated with BMI both before pregnancy and at screening for GDM. The effect of maternal age at pregnancy and weight change during pregnancy at GDM screening on adipokines and insulin resistance might be less pronounced than the effect of maternal obesity.

Women with a history of gestational diabetes (p-GDM) are at increased risk of developing type 2 diabetes mellitus (DM2) later in life, and therefore at increased risk for future cardiovascular disease. Three months after delivery we investigated the plasma levels of plasminogen activator inhibitor type 1 (PAI-1), tissue plasminogen activator (t-PA), fibrinogen and von Willebrand factor (vWF) in 74 women with p-GDM and 20 healthy females with normal glucose tolerance during and after pregnancy, as well as the relation of fibrinolytic parameters to insulin resistance and glycaemic control. All women underwent an oral (OGTT) as well as an intravenous glucose tolerance test (FSIGT). Mathematical model analysis disclosed that 50% (n=37 each) of the p-GDM subjects had normal (NIS) or impaired (IIS) insulin sensitivity. Parameters of interest were determined using commercially available test systems. Women with p-GDM and IIS had significantly increased body fat mass (BFM) (Pwomen with p-GDM and NIS and controls, whereas the waist to hip ratio (WHR) was similar in both p-GDM groups but was higher compared with the controls (Pwomen with p-GDM and IIS compared with women with p-GDM and NIS and the controls (Pwomen with IIS had higher PAI-1 levels than lean women with IIS (Pwomen with IIS (Pwomen with IIS independently of their glucose tolerance status (Pwomen with IIS and depends on plasma proinsulin and abdominal obesity. An increase of the PAI-1/SI ratio further characterizes obese insulin-resistant p-GDM women who may be at risk for diabetes and angiopathy.

To assess changes in insulin resistance and β-cell function in a multiethnic cohort of women in Oslo, Norway, from early to 28 weeks' gestation and 3 months post partum and relate the findings to gestational diabetes mellitus (GDM). Population-based cohort study of 695 healthy pregnant women from Western Europe (41%), South Asia (25%), Middle East (15%), East Asia (6%) and elsewhere (13%). Blood samples and demographics were recorded at mean 15 (V1) and 28 (V2) weeks' gestation and 3 months post partum (V3). Universal screening was by 75 g oral glucose tolerance test at V2, GDM with modified IADPSG criteria (no 1-h measurement): fasting plasma glucose (PG) ≥5.1 or 2-h PG ≥8.5 mmol/l. Homeostatic model assessment (HOMA)-β (β-cell function) and HOMA-IR (insulin resistance) were calculated from fasting glucose and C-peptide. Characteristics were comparable across ethnic groups, except age (South Asians: younger, Pinsulin resistant than Western Europeans at V1. From V1 to V2, the increase in insulin resistance was similar across the ethnic groups, but the increase in β-cell function was significantly lower for the East and South Asians compared with Western Europeans. GDM women compared with non-GDM women were more insulin resistant at V1; from V1 to V2, their β-cell function increased significantly less and the percentage increase in β-cell function did not match the change in insulin resistance. Pregnant women from East Asia and South Asia were more insulin resistant and showed poorer HOMA-β-cell function than Western Europeans.

Maternal outcomes and follow-up after gestational diabetes mellitus

Science.gov (United States)

Kim, C.

2014-01-01

Gestational diabetes mellitus reflects impaired maternal insulin secretion relative to demand prior to pregnancy, as well as temporary metabolic stressors imposed by the placenta and fetus. Thus, after delivery, women with gestational diabetes have increased risk of diabetes and recurrent gestational diabetes because of their underlying impairment, which may be further exacerbated by fat accretion during pregnancy and post-partum deterioration in lifestyle behaviours. This hypothetical model is discussed in greater detail, particularly the uncertainty regarding pregnancy as an accelerator of β-cell decline and the role of gestational weight gain. This report also presents risk estimates for future glucose intolerance and diabetes and reviews modifiable risk factors, particularly body mass and lifestyle alterations, including weight loss and breastfeeding. Non-modifiable risk factors such as race/ethnicity and insulin use during pregnancy are also discussed. The review concludes with current literature on lifestyle modification, recommendations for post-partum glucose screening, and future directions for research to prevent maternal disease.

The aim of the present meta-analysis was to determine the efficacy and safety of metformin for the treatment of women with gestational diabetes mellitus (GDM). We searched databases, including PubMed, Embase and the Cochrane Central Register of Controlled Trials, for randomized controlled trials (RCTs) comparing metformin and insulin treatments in women with GDM. We carried out statistical analyses using RevMan 2011 and used the Grading of Recommendations, Assessment, Development, and Evaluations profiler to rate the quality of evidence of the primary outcomes. We analysed eight studies involving 1592 subjects. Meta-analysis of the RCTs showed that metformin had statistically significant effects on pregnancy-induced hypertension [PIH; risk ratio (RR) 0.54; 95% confidence interval (CI) 0.31, 0.91]. However, its effects on neonatal hypoglycaemia (RR 0.80; 95% CI 0.62, 1.02), rate of large-for-gestational age infants (RR 0.77; 95% CI 0.55, 1.08), respiratory distress syndrome (RR 1.26; 95% CI 0.67, 2.37), phototherapy (RR 0.94; 95% CI 0.67, 1.31) and perinatal death (RR 1.01; 95% CI 0.11, 9.53) were not significant. Our analyses suggest that there is no clinically relevant difference in efficacy or safety between metformin and insulin; however, metformin may be a good choice for GDM because of the lower risk of PIH. The advantages of metformin in terms of glycaemic control, PIH incidence and gestational age at birth are unclear, and should be verified in further trials. © 2015 The British Pharmacological Society.

Exercise and its role in gestational diabetes mellitus

Directory of Open Access Journals (Sweden)

Chen Wang

2016-12-01

Full Text Available Gestational diabetes mellitus (GDM refers to diabetes diagnosed in the second or third trimester of pregnancy that is not clearly either type 1 or type 2 diabetes. GDM is a common medical complication in pregnancy that has been rapidly increasing worldwide. GDM is associated with both short- and long-term health issues for both mothers and offspring. Consistent with type 2 diabetes, peripheral insulin resistance contributes to the hyperglycemia associated with GDM. Accordingly, it is important to identify strategies to reduce the insulin resistance associated with GDM. To date, observational studies have shown that exercise can be a non-invasive therapeutic option for preventing and managing GDM that can be readily applied to the antenatal population. However, the relevant mechanisms for these outcomes are yet to be fully elucidated. The present review aimed to explain the potential mechanisms of exercise from the perspective of reducing the insulin resistance, which is the root cause of GDM. Exercise recommendations and opinions of exercise during pregnancy are briefly summarized. Keywords: Exercise, Gestational diabetes mellitus, Insulin resistance, Pregnancy

Gestational diabetes mellitus is defined by new-onset glucose intolerance during pregnancy. About 2-5% of all pregnant women develop gestational diabetes during their pregnancies and the prevalence has increased considerably during the last decade. This metabolic condition is manifested when pancreatic β-cells lose their ability to compensate for increased insulin resistance during pregnancy, however, the pathogenesis of the disease remains largely unknown. Gestational diabetes is strongly associated with adverse pregnancy outcome as well as with long-term adverse effects on the offspring which likely occurs due to epigenetic modifications of the fetal genome. In the current review we address gestational diabetes and the short and long term complications for both mothers and offspring focusing on the importance of fetal programming in conferring risk of developing diseases in adulthood.

Metformin is widely used in treatment of type 2 diabetes. However, whether it is safe for use in pregnancy is controversial. A search for relevant studies were performed using PubMed (1948-2014), Embase (1974-2014), the Web of knowledge (1950-2014), and the Cochrane database, included all randomized control trials published in English. Eight RCTs (1712 patients with gestational diabetes mellitus) were retrieved; of those 853 patients were given metformin, and 859 patients were given insulin. Our results showed that metformin does not increase risk of prematurity (RR = 1.26; 95 % CI [0.89, 1.79], P = 0.19). In addition, metformin can either decrease the total weight gain [MD = -1.49, 95 % CI (-2.66, -0.31), P = 0.01] or weight gain after randomization [MD = -1.23, 95 % CI (-1.75, -0.71), P metformin also significantly decreased the risk of neonatal hypoglycemia [RR = 0.58, 95 % CI (0.43, 0.78), P = 0.0003] and admission rates to neonatal intensive care units [RR = 0.74, 95 % CI (0.61, 0.89), P = 0.002]. No other adverse effects were observed, such as hyperbilirubinaemia [RR = 0.83, 95 % CI (0.64, 1.08), P = 0.16], large for gestational age [RR = 0.85, 95 % CI (0.68, 1.05), P = 0.14], small for gestational age [RR = 0.92, 95 % CI (0.61, 1.39), P = 0.69], macrosomia [RR = 0.75, 95 % CI (0.54, 1.03), P = 0.07] or respiratory distress syndrome [RR = 0.88, 95 % CI (0.55, 1.41), P = 0.6]. Metformin may be beneficial in treating gestational diabetes. However, even more studies are needed to provide more evidence for the future use of metformin.

Hyperglycemia is an essential risk factor for mothers and fetuses in gestational diabetes. Clinical observation has indicated that the offspring of mothers with diabetes shows impaired somatosensory function and IQ. However, only a few studies have explored the effects of hyperglycemia on fetal brain development. Neurodevelopment is susceptible to environmental conditions. Thus, this study aims to investigate the effects of maternal hyperglycemia on fetal brain development and to evaluate insulin and insulin-like growth factor-I (IGF-I) signals in fetal brain under hyperglycemia or controlled hyperglycemia. At day 1 of pregnancy, gestational rats were intraperitoneally injected with streptozocin (60 mg/kg). Some of the hyperglycemic gestational rats were injected with insulin (20 IU, two times a day) to control hyperglycemia; the others were injected with saline of equal volume. The gestational rats were sacrificed at days 14, 16, and 18 of embryo development. The dendritic spines of subplate cortex neurons in the fetal brain were detected by Golgi-Cox staining. The mRNA levels of insulin receptors (IRs) and IGF-IR in the fetal brain were measured using qRT-PCR. The protein levels of synaptophysin, IR, and IGF-IR in the fetal brain were detected by western blot. No significant difference in fetal brain formation was observed between the maternal hyperglycemic group and insulin-treated group. By contrast, obvious retardation of dendritic development in the fetus was observed in the maternal hyperglycemic group. Similarly, synaptophysin expression was lower in the fetus of the maternal hyperglycemic group than in that of the insulin-treated group. The mRNA and protein expression levels of IRs in the fetal brain were higher in the hyperglycemic group than in the insulin-treated group. By contrast, the levels of IGF-IR in the brain were lower in the fetus of the maternal hyperglycemic group than in that of the insulin-treated group. These results suggested that

Intensive treatment regimens including early initiation of insulin treatment are important to prevent late complications in type 2 diabetes. The assumed risk of severe hypoglycemia (SH) is a major barrier to initiation of insulin treatment. To assess the relevance of this risk we evaluated...... the frequency of SH as reported in the literature. Using Medline and Embase search we identified 11 studies (5 retrospective and 6 prospective) including at least 50 patients with insulin-treated type 2 diabetes followed for at least 6 months in which frequency of SH was reported. The incidence of SH....... Only few studies looked into the impact of risk factors on the rate of SH. Impaired hypoglycemia awareness, high age, long duration of diabetes and insulin therapy increased the risk, while no association was found with HbA1c and insulin dose.

Siddiqui, Khalid; George, Teena P

Diabetes is estimated to be one of the major causes of deaths in most countries due to its high prevalence rate, which was 8.8% in 2015. Hyperglycemia detected during pregnancy is known as gestational diabetes mellitus and it increases the potential risk of development of Type 2 diabetes in mothers with its varying prevalence rate of 1-14% in different populations. It also leads to the higher risk of developing abnormal glucose tolerance and obesity in their child at an early age. Recent studies show that potential mediators of insulin resistance such as adipokines - adiponectin, leptin and resistin are important for glucose and lipid metabolism. Adipokines are directly involved in the regulation of insulin secretion and insulin sensitivity in the liver, muscle and adipose tissue. It is also involved in inflammation, adipose tissue accumulation, adverse fat distribution and subsequently affects glucose metabolism. This review highlights the role of resistin (an adipokine) in the development of gestational diabetes mellitus.

Probiotic supplement might be beneficial for gestational diabetes mellitus. However, the results remained controversial. We conducted a systematic review and meta-analysis to explore the efficacy of probiotic supplement in gestational diabetes mellitus. PubMed, Embase, Web of science, EBSCO, and Cochrane Library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of probiotic supplement in gestational diabetes mellitus were included. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. The primary outcome were fasting serum insulin and fasting plasma glucose. Meta-analysis was performed using the fixed-effect or random-effect model. Six RCTs involving 830 patients were included in the meta-analysis. Overall, compared with control intervention in gestational diabetes mellitus, probiotic supplementation intervention was found to significantly reduce fasting serum insulin (Std. mean difference = -0.95; 95% CI = -1.73 to -0.17; p gestational age (Std. mean difference = 0.07; 95% CI = -0.20-0.34; p = .63), and gestational weight (Std. mean difference = -0.11; 95% CI = -0.38-0.16; p = .43). Compared with control intervention in gestational diabetes mellitus, probiotic supplementation was found to significantly reduce insulin resistance (HOMA-IR) and fasting serum insulin, but had no substantial influence on fasting plasma glucose, gestational age and gestational weight.

Gestational diabetes mellitus (GDM) is common and is accompanied with other comorbidities. Challenges to treatment exist at our institute as it serves women with low income. This study assessed the burden of comorbidities and the outcome of GDM. This was a prospective, observational study of women with gestational diabetes attending the obstetrics department from September 2012 to April 2014. GDM was diagnosed based on the International Association of Diabetes and Pregnancy Study Groups criteria. Medical comorbidities were noted, and lipid profile was done. All the women were followed up till delivery, and the complications were recorded. Age- and parity-matched pregnant women with normal oral glucose tolerance test were recruited as controls. One hundred and thirty-nine women were followed up till delivery. The average age was 28 years. Eighteen percent had bad obstetric history. The average body mass index was 28.8. Twenty-five percent had gestational hypertension (HTN), and 6.4% had chronic HTN. Thirty percent had hypothyroidism. 65% women received insulin. The glucose values were within the recommended range in 60% of the women. Maternal hypoglycemia occurred in 7 (5%) women. Forty-four percent of the women required cesarean section and 34% had complications either during pregnancy or labor. Three neonates had macrosomia. Twenty-six neonates (20%) required admission to the Neonatal Intensive Care Unit. Four neonates (3%) died. Newborns of mothers whose GDM optimally treated had less complications. Gestational diabetes is associated with HTN, hypothyroidism, obesity, and lipid abnormalities. The majority of women required insulin for treatment and optimal control of blood glucose resulted in lower neonatal complications.

Gestational diabetes is associated with risk for metabolic disease later in life. Using a cross-species approach in rat and humans, we examined the hypothesis that gestational diabetes during pregnancy triggers changes in the methylome of the offspring that might be mediating these risks. We show in a gestation diabetes rat model, the Cohen diabetic rat, that gestational diabetes triggers wide alterations in DNA methylation in the placenta in both candidate diabetes genes and genome-wide promoters, thus providing evidence for a causal relationship between diabetes during pregnancy and DNA methylation alterations. There is a significant overlap between differentially methylated genes in the placenta and the liver of the rat offspring. Several genes differentially methylated in rat placenta exposed to maternal diabetes are also differentially methylated in the human placenta of offspring exposed to gestational diabetes in utero. DNA methylation changes inversely correlate with changes in expression. The changes in DNA methylation affect known functional gene pathways involved in endocrine function, metabolism, and insulin responses. These data provide support to the hypothesis that early-life exposures and their effects on metabolic disease are mediated by DNA methylation changes. This has important diagnostic and therapeutic implications.

To evaluate the effect of metformin and insulin in glycemic control and compare pregnancy outcome in women with gestational diabetes mellitus (GDM). This randomized controlled trial was conducted in GDM women with singleton pregnancy and gestational age between 20 and 34 weeks who did not achieve glycemic control on diet were assigned randomly to receive either metformin (n=80) or insulin (n=80). The primary outcomes were maternal glycemic control and birth weight. The secondary outcomes were neonatal and obstetric complications. Two groups were comparable regarding the maternal characteristics. Two groups were similar in mean FBS (P=0.68) and postprandial measurements (P=0.87) throughout GDM treatment. The neonates of metformin group had less rate of birth weight centile >90 than insulin group (RR: 0.5, 95% CI: 0.3-0.9, P=0.012). Maternal weight gain was reduced in the metformin group (P0.05). In metformin group 14% of women needed to supplemental insulin to achieve euglycemia. Metformin is an effective and safe alternative treatment to insulin for women with GDM. This study does not show significant risk of maternal or neonatal adverse outcome with the use of metformin. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Gastric emptying of 99m Tc labelled liquid and solid meals were studied in 112 long-standing insulin insulin treated diabetics to evaluate the relationship of gastroparesis to patients age, sex, gastrointestinal symptoms, diabetic neuropathic complication and glycemic control, and to evaluate the influence of gastric emptying and timing of insulin injection as modifying factors for blood glucose control aiming at objective optimization of timing of insulin injection for every individual patient using the proposed equation: time of insulin injection=onset of insulin action -solid lag time. Patients were classified into three group: A) no neuropathy; B) peripheral neuropathy; and C) peripheral and autonomic neuropathy and compared to healthy volunteers as controls. Diabetics showed statistically significant prolonged gastric lag time and T1/2 for both liquid and solid meals compared to those of controls

To investigate the function of islet β cells in patients with gestational diabetes mellitus (GDM), serum insulin and C-peptide (C-P) excitatory test levels were measured dynamically by radioimmunoassay in 41 patients with GDM and 30 normal pregnant controls. The results showed that there were significant difference in insulin and C-peptide excitatory test levels between normal pregnancy for 32-40 weeks and patients with GDM (P < 0.001). The secretory peak of insulin occurred at 60 min in normal pregnancy, while at 120 min in patients with GDM, and the recovery postponed in patients with GDM. The peak time for C-P was just as same as that of insulin, but the peak error for C-P between normal pregnant controls and patients with GDM was more larger than that for insulin and it recovered more slowly. It suggested that majority of islet β cells in patients with GDM were good enough for response to islet resistance factors and big stress from pregnancy, and also suggested a relation between pregnancy and islet β cells function

In this experiment, we established an animal model of gestational diabetes mellitus rats using streptozotocin. Using the rat model of GDM, the pregnant rats in 1-19d were divided into three groups: (1) Zuogui Wan gestational diabetes mellitus group (group I, n = 12), (2) gestational diabetes mellitus rats as the control group (group II, n = 11), and (3) rats of normal pregnancy group (group III, n = 11). Compared with gestational diabetes mellitus rats as the control group, Zuogui Wan can change the indexes of fasting blood glucose, body weight, total cholesterol, insulin, and metabolism cage index significantly in Zuogui Wan gestational diabetes mellitus group. We can conclude that Zuogui Wan has the therapeutic effect on gestational diabetes mellitus. PMID:25136475

Background Nowadays, there have been increasing studies comparing metformin with insulin. But the use of metformin in pregnant women is still controversial, therefore, we aim to examine the efficiency and safety of metformin by conducting a meta-analysis of randomized controlled trials (RCTs) comparing the effects of metformin with insulin on glycemic control, maternal and neonatal outcomes in gestational diabetes mellitus (GDM). Methods We used the key words “gestational diabetes” in combination with “metformin” and searched the databases including Pubmed, the Cochrane Library, Web of knowledge, and Clinical Trial Registries. A random-effects model was used to compute the summary risk estimates. Results Meta-analysis of 5 RCTs involving 1270 participants detected that average weight gains after enrollment were much lower in the metformin group (n = 1006, P = 0.003, SMD = −0.47, 95%CI [−0.77 to −0.16]); average gestational ages at delivery were significantly lower in the metformin group (n = 1270, P = 0.02, SMD = −0.14, 95%CI [−0.25 to −0.03]); incidence of preterm birth was significantly more in metformin group (n = 1110, P = 0.01, OR = 1.74, 95%CI [1.13 to 2.68]); the incidence of pregnancy induced hypertension was significantly less in the metformin group (n = 1110, P = 0.02, OR = 0.52, 95%CI [0.30 to 0.90]). The fasting blood sugar levels of OGTT were significantly lower in the metformin only group than in the supplemental insulin group (n = 478, P = 0.0006, SMD = −0.83, 95%CI [−1.31 to −0.36]). Conclusions Metformin is comparable with insulin in glycemic control and neonatal outcomes. It might be more suitable for women with mild GDM. This meta-analysis also provides some significant benefits and risks of the use of metformin in GDM and help to inform further development of management guidelines. PMID:23724063

Metformin in gestational diabetes: An emerging contender

Full Text Available Gestational diabetes mellitus (GDM is defined as any degree of glucose intolerance occurring first time during pregnancy. Its prevalence is simultaneously increasing with the global rise of diabesity. GDM commonly develops, when maternal glucose metabolism is unable to compensate for the progressive development of insulin resistance, arising primarily from the consistently rising diabetogenic placental hormones. It classically develops during the second or third trimester. Theoretically, insulin sensitizers should have been the ideal agent in its treatment, given the insulin resistance, the major culprit in its pathogenesis. Fortunately, majority of women can be treated satisfactorily with lifestyle modification, and approximately 20% requires more intensive treatment. For several decades, insulin has been the most reliable treatment strategy and the gold standard in GDM. Metformin is effective insulin sensitizing agent and an established first line drug in type 2 diabetes currently. As it crosses the placenta, a safety issue remains an obstacle and, therefore, metformin is currently not recommended in the treatment of GDM. Nevertheless, given the emerging clinically equivalent safety and efficacy data of metformin compared to insulin, it appears that it may perhaps open a rather new door in managing GDM. The aim of this review is to critically analyze, the safety and efficacy data of metformin regarding its use in GDM and pregnant mothers with polycystic ovarian disease, which has emerged in past decades.

Gestational diabetes is considered a variant of diabetes mellitus as they share a common pathophysiological basis: insulin resistance in target and insufficient secretion of it by pancreatic p-cell bodies. Pregnancy is a unique physiological situation provides an opportunity to identify future risk of diabetes mellitus. To determine the long-term incidence of diabetes mellitus in women who have previously been diagnosed with gestational diabetes and identifying clinical risk factors for developing the same. nested case-control cohort study. 671 patients between 1996 and 2009 were diagnosed with gestational diabetes were selected. The incidence of diabetes mellitus was estimated and 2 subgroups were formed: Group A or cases: women who develop diabetes mellitus after diagnosis of gestational diabetes. Group B or control: random sample of 71 women with a history of gestational diabetes in the follow-up period remained normoglycemic. Both groups were studied up to 18 years postpartum. By studying Kaplan Meier survival of the influence of different gestational variables it was obtained in the later development of diabetes mellitus with time parameter and COX models for categorical variables were applied. Significant variables were studied by multivariate Cox analysis. In all analyzes the Hazard ratio was calculated with confidence intervals at 95%. The incidence of diabetes mellitus was 10.3% in patients with a history of gestational diabetes. They were identified as risk factors in the index pregnancy to later development of diabetes mellitus: greater than 35 and younger than 27 years maternal age, BMI greater than 30 kg/m2, hypertensive disorders of pregnancy, insulin therapy, poor metabolic control and more than a complicated pregnancy with gestational diabetes. Clinical factors have been identified in the pregnancy complicated by gestational diabetes that determine a higher probability of progression to diabetes mellitus in the medium and long term.

The aim of this study was to observe insulin resistance and β-cell function changes among women diagnosed with gestational impaired glucose tolerance or gestational diabetes mellitus (GDM) in mid-pregnancy. Sixty-four pregnant women receiving prenatal care underwent an oral glucose tolerance test at 20-24 weeks of gestation and an insulin release test. The GDM group included 34 pregnant women diagnosed with gestational impaired glucose tolerance or GDM, and the subjects with normal blood glucose were the control group. Insulin resistance and islet β-cell function changes were observed with the oral glucose tolerance test and insulin release test. The homeostatic model assessment-β levels in late pregnancy were higher than those in mid-pregnancy for both groups, and the primary time effect was statistically significant. The early insulin secretion index (ΔI(30)/ΔG(30)) values in mid- and late pregnancy were lower in the GDM group. The values of the area under the curve of blood glucose in mid- and late pregnancy were higher in the GDM group than those in the control group. Insulin resistance was higher in GDM patients than in normal pregnant women. Insulin resistance was aggravated, and β-cell's ability to compensate for the increased insulin resistance by modulating insulin secretion was aggravated, as gestational week increased in women with gestational diabetes and normal pregnant women. Insulin resistance in women with GDM is higher than in pregnant women with normal metabolism of glucose. © 2012 The Authors.

The aim of this study was to determine the effect of gestational diabetes mellitus (GDM) on fetal insulin resistance or β-cell function in Chinese pregnant women with GDM. Maternal fasting blood and venous cord blood samples (reflecting fetal condition) were collected in 65 well-controlled Chinese GDM mothers (only given dietary intervention) and 83 control subjects. The insulin, glucose and proinsulin concentrations of both maternal and cord blood samples were measured, and the homeostasis model assessment of insulin resistance (HOMA-IR) and the proinsulin-to-insulin ratios (an indicator of fetal β-cell function) were calculated in maternal and cord blood respectively. Both maternal and fetal levels of insulin, proinsulin and HOMA-IR but not proinsulin-to-insulin ratios were significantly higher in the GDM group than in the control group (maternal insulin, 24.8 vs. 15.4 µU/mL, P = 0.004, proinsulin, 23.3 vs. 16.2 pmol/L, P = 0.005, and HOMA-IR, 5.5 vs. 3.5, P = 0.041, respectively; fetal: insulin, 15.1 vs. 7.9 µU/mL, Pinsulin ratios was significantly correlated to maternal HOMA-IR (r = 0.307, P = 0.019), in the pregnant women with GDM. Fetal insulin resistance was higher in Chinese pregnant women with GDM than control subjects, and correlated with maternal insulin resistance.

Full Text Available BackgroundWe examined the change in the levels of incretin hormone and effects of glucose-dependent insulinotropic polypeptide (GIP and glucagon-like peptide 1 (GLP-1 on insulin secretion in women with previous gestational diabetes (pGDM.MethodsA 75-g oral glucose tolerance test (OGTT was conducted on 34 women with pGDM. In addition, 11 women with normal glucose tolerance, matched for age, height and weight, were also tested. The insulin, GIP, GLP-1, and glucagon concentrations were measured, and their anthropometric and biochemical markers were also measured.ResultsAmong 34 women with pGDM, 18 had normal glucose tolerance, 13 had impaired glucose tolerance (IGT and 1 had diabetes. No significant differences were found in GLP-1 concentration between the pGDM and control group. However, a significantly high level of glucagon was present in the pGDM group at 30 minutes into the OGTT. The GIP concentration was elevated at 30 minutes and 60 minutes in the pGDM group. With the exception of the 30-minute timepoint, women with IGT had significantly high blood glucose from 0 to 120 minutes. However, there was no significant difference in insulin or GLP-1 concentration. The GIP level was significantly high from 0 to 90 minutes in patients diagnosed with IGT.ConclusionGLP-1 secretion does not differ between pGDM patients and normal women. GIP was elevated, but that does not seem to induce in increase in insulin secretion. Therefore, we conclude that other factors such as heredity and environment play important roles in the development of type 2 diabetes.

Various studies in placental tissue suggest that diabetes mellitus alters the expression of glucose transporter (GLUT) proteins, with insulin therapy being a possible modulatory factor. The aim of the present study was quantitative evaluation of the expression of glucose transporters (GLUT-1, GLUT-4, GLUT-9) in the placenta of women in both, uncomplicated and diabetic pregnancy. Additionally, the effect of insulin therapy on the expression of selected glucose transporter isoforms was analyzed. Term placental samples were obtained from healthy control (n = 25) and diabetic pregnancies, including diet-controlled gestational diabetes mellitus (GDMG1) (n = 16), insulin-controlled gestational diabetes mellitus (GDMG2) (n = 6), and pre-gestational diabetes mellitus (PGDM) (n = 6). Computer-assisted quantitative morphometry of stained placental sections was performed to determine the expression of selected glucose transporter proteins. Morphometric analysis revealed a significant increase in the expression of GLUT-4 and GLUT-9 in insulin-dependent diabetic women (GDMG2 + PGDM) as compared to both, control and GDMG1 groups (p diabetic pregnancies. In addition, insulin therapy may increase placental expression of GLUT-4 and GLUT-9, and partially GLUT-1, in women with GDMG2/PGDM.

To investigate the relationship between mid-gestational serum uric acid and birth weight in diabetic pregnant women with or without insulin resistance. In a prospective cohort study, fasting uric acid, blood glucose, and serum insulin were measured in 247 pregnant women between 20-22 weeks of gestational period. Insulin resistance was estimated using the homeostasis model assessment-insulin resistance (HOMA-IR). Stratification analysis and independent t-test was used to assess the association between uric acid and birth weights regarding to insulin resistance. The means of the mid-gestational serum uric acid concentrations were not significantly different in women with and without insulin resistance. But stratification analysis showed that there was a significant difference between uric acid concentration and macrosomic birth in diabetic women without insulin resistance. Higher mid - gestation serum uric acid concentration, even if it does not exceed the normal range, is accompanied by lower birth weight only in non-insulin resistance women. Insulin resistance could have a negative confounding effect on hyperuriemia and birth weight.

Full Text Available OBJECTIVE: Recent studies suggested that secreted protein acidic and rich in cysteine (SPARC, a novel adipokine, is a key player in the pathology of obesity and type 2 diabetes. We aimed to determine whether concentrations of SPARC were altered in patients with gestational diabetes mellitus (GDM compared to normal glucose tolerance (NGT controls and to investigate the relationships between SPARC and metabolic parameters in pregnant women. DESIGN/METHODS: Cross-sectional study of 120 pregnant women with GDM and 60 controls with NGT, in a university hospital setting. Plasma levels of SPARC, adiponectin, fibroblast growth factor 21 (FGF21, insulin and proinsulin were determined by ELISA. RESULTS: GDM women had higher SPARC and lower adiponectin than NGT subjects; no difference was found in FGF21. SPARC levels were the lowest in subjects in the third tertile of insulin sensitivity index (ISIOGTT and correlated positively with pre-pregnant BMI, insulin and 3 h glucose during 100-g OGTT, HOMA-IR, fasting proinsulin, hsCRP and white blood cells count, and negatively with ISIOGTT, when adjusting for gestational age. Triglyceride (TG, Apolipoprotein A1, apolipoprotein B and lipoprotein (a correlated with SPARC in partial Pearson correlation. Correlations between SPARC with adiponectin, systolic blood pressure and TG were marginally significant in partial Spearman correlation analysis. In multivariate regression analysis, SPARC was an independent negative indicator of ISIOGTT. CONCLUSIONS: SPARC levels are correlated significantly with inflammation and may also be correlated with dyslipidemia and represent an independent determinant of insulin resistance in late pregnancy, indicating a potential role of SPARC in the pathophysiology of GDM.

Full Text Available Korean women with a history of gestational diabetes mellitus (GDM have a 3.5 times greater risk of developing postpartum diabetes than the general population. The incidence of type 2 diabetes mellitus in early postpartum is reported as 10-15% in Korean women. A prospective follow-up study on Korean women with GDM showed that approximately 40% of women with previous GDM were expected to develop diabetes within 5 years postpartum. Independent risk factors for the development of diabetes in Korean women with previous GDM are pre-pregnancy body weight, gestational age at diagnosis, antepartum hyperglycemia on oral glucose tolerance test, low insulin response to oral glucose load, and family history of diabetes. Women with postpartum diabetes have greater body mass indexes, body weight, and waist circumferences than women with normal glucose tolerance. Multiple logistic regression analysis has revealed that waist circumference is the strongest obesity index along with systolic blood pressure and that triglyceride levels are a major independent risk factor for developing diabetes. These results in Korean women with previous GDM underline the importance of postpartum testing in Korean women diagnosed with GDM, and demonstrate that impaired B-cell function, obesity, and especially visceral obesity, are associated with the development of diabetes.

We investigate the impact of genetic variants on transiently upregulated gestational insulin signaling. We recruited 1152 unrelated nondiabetic pregnant Han Chinese women (age 28.5 ± 4.1 years; body mass index [BMI] 21.4 ± 2.6 kg/m(2)) and gave them oral glucose tolerance tests. Matsuda index of insulin sensitivity, homeostatic model assessment of insulin resistance, indices of insulin disposition, early-phase insulin release, fasting state, and 0 to 120 minute's proinsulin to insulin conversion were used to dissect insulin physiological characterization. Several variants related to β-cell function were genotyped. The genetic impacts were analyzed using logistic regression under an additive model. By adjusting for maternal age, BMI, and the related interactions, the genetic variants in ABCC8, CDKAL1, CDKN2A, HNF1B, KCNJ11, and MTNR1B were detected to impact gestational insulin signaling through heterogeneous mechanisms; however, compared with that in nonpregnant metabolism, the genetic effects seem to be eminently and heavily influenced by maternal age and BMI, indicating possible particular mechanisms underlying gestational metabolism and diabetic pathogenesis. © The Author(s) 2015.

Retinol-binding protein 4 (RBP4) is a circulating retinol transporter that is strongly associated with insulin resistance. The aim of this study was to evaluate the RBP4 and retinol level in rat model of gestational diabetes mellitus and the relationship between retinol-free RBP4 (apo-RBP4), retinol-bound RBP4 (holo-RBP4) and insulin resistance. Pregnant rats were administered streptozotocin to induce diabetes. The RBP4 and retinol levels were evaluated in GDM and normal pregnant rats. After then, normal pregnant rats were divided into two groups to receive either apo-RBP4 or vehicle injection. The metabolic parameters and insulin signaling in adipose tissue, skeletal muscle and liver were determined in apo-RBP4 and control groups. Primary human adipocytes were cultured in vitro with different proportions of apo-RBP4 and holo-RBP4 for 24 h. The interaction between RBP4 and STRA6 was assessed by co-immunoprecipitation, and the expression of JAK-STAT pathway and insulin signaling were detected by Western blotting and immunofluorescence. We found increases in serum RBP4 levels and the RBP4:retinol ratio but not in the retinol levels in GDM rats. Exogenous apo-RBP4 injection attenuated insulin sensitivity in pregnant rats. In vitro, a prolonged interaction between RBP4 and STRA6 was observed when apo-RBP4 was present. In response to increased apo-RBP4 levels, cells showed elevated activation of the JAK2/STAT5 cascade and SOCS3 expression, decreased phosphorylation of IR and IRS1, and attenuated GLUT4 translocation and glucose uptake upon insulin stimulation. Apo-RBP4 is a ligand that activates the STRA6 signaling cascade, inducing insulin resistance in GDM.

This study evaluated mothers with diabetes to determine whether prepregnancy body mass index (BMI), BMI on delivery or gestational weight gain (GWG) had the greatest impact on maternal and neonatal outcomes. We retrospectively examined the medical charts of 634 full-term infants born to mothers with gestational diabetes mellitus not requiring insulin (n = 476), gestational diabetes mellitus requiring insulin (n = 140) and insulin-dependent diabetes mellitus (n = 18). Data regarding maternal BMI before pregnancy and on delivery were recorded, as well as maternal and neonatal complications. Infants born to women who gained more than the recommended weight during pregnancy had higher birthweights, higher rates of meconium-stained amniotic fluid and neonatal hypoglycaemia. Using logistic regression, Caesarean section delivery was predicted by gestational diabetes requiring insulin, with an odds ratio (OR) of 1.76, maternal hypertension (OR 2.4), infants born large for gestational age (OR 2.78) and maternal BMI ≥ 30 on delivery (OR 1.06). Neonatal complications were predicted by maternal insulin-dependent diabetes (OR 5.21), lower gestational age (OR 0.8) and GWG above the recommended amount (OR 1.56). Women with diabetes should be made aware that higher GWG can lead to Caesarean section delivery, infant macrosomia and other neonatal complications. ©2015 Foundation Acta Paediatrica.

Variation in TCF7L2 gene is associated with type 2 diabetes and with gestational diabetes mellitus in several populations, but there are no data in Mexican women with gestational diabetes mellitus. In this study, we examined metabolic and hormonal measurements as well as TCF7L2 genetic variants. We selected 108 pregnant women with normal glucose tolerance and 90 with gestational diabetes mellitus according to 2010 American Diabetes Association criteria matched for gestational week. We collected data on blood pressure, body mass index (BMI) and concentrations of blood glucose, HbA1c , lipids profile, insulin and glucagon-like peptide-1 (GLP-1). The genotyping of rs7903146 and rs12255372 polymorphisms were made with polymerase chain reaction-restriction fragment length polymorphism. Actual and pre-gestational BMI, fasting glucose and HbA1c were higher (p gestational diabetes mellitus women than euglycemic women. No significant differences were found for lipids, insulin and homeostasis model assessment-insulin resistance. Gestational diabetes mellitus women had high GLP-1 levels (32 vs 24, p gestational diabetes women was significantly higher than that in euglycemic women (χ²  = 8.96; p gestational diabetes mellitus (OR = 9.1, 95% CI 2.8-29, p gestational BMI and rs12255372 risk allele are independently associated with gestational diabetes. The elevated GLP-1 levels in gestational diabetes women suggested some abnormality in insulin secretion. The low β-cell function, high pre-gestational BMI and rs12255372 risk allele are risk factors independently associated with the development of gestational diabetes.

2017-07-01

Gestational diabetes mellitus (GDM) is defined as glucose intolerance with onset during pregnancy. During pregnancy, women with GDM develop insulin resistance, which results in altered glucose tolerance. As a result, there are frequent episodes of hyperglycemia and high levels of circulating amino acids, increasing the transfer of nutrients to the fetus. This article discusses the role of the mother-baby nursing in the care of neonates born to women with gestational diabetes.

Gestational diabetes is a risk factor for perinatal complications; include shoulder dystocia, birth injuries such as bone fractures and nerve palsies. It is associated with later development of type 2 diabetes, the risk of macrosomia and other long-term health effects of infants born to diabetic mothers. The study assesses placental peptides and maternal factors as potential predictors of gestational diabetes among pregnant women. A total of 200 pregnant women were recruited for the study, 150 pregnant women without pre gestational diabetes including 50 women with low risk factors of diabetes as controls and 50 other pregnant women with pregestational diabetes as control. Fasting blood glucose and the lipid profile were determined by enzymatic methods using Envoy® 500 reagents (Vital Diagnostics, USA). Glycated haemoglobin was assessed using the Cation Exchange resin method. Leptin and the Human Placenta Lactogen were assayed using the Sandwich-ELISA technique. Beta chorionic gonadotrophin, insulin, progesterone and estradiol were determined using chemilumiscence imunoassay technique on MAGLUMI 600 analyzer. Anthropometry, including BMI and blood pressure were also measured. Fasting plasma glucose (FBG), insulin, insulin resistance, glycated haemoglobin and Human Placenta Lactogen(HPL)were significantly (p0.05) in estradiol, insulin, insulin resistance and HPL between the pregnant women who developed gestational diabetes and those who did not. Leptin, progesterone and FBG were significantly increased in those who developed GDM. The risk of developing gestational diabetes increased with overweight (OR = 1.76, P = 0.370) and family history of diabetes (OR = 2.18, P = 0.282). Leptin, progesterone, estradiol estimated in this study were increased in the gestational diabetes mellitus women and fairly predicted gestational diabetes in the non-diabetics pregnant women. Obesity, aging and family history of diabetes were strongly predictive of gestational diabetes.

Objective: To explore the dynamic of tumor necrosis factor-alpha (TNF-α)and its correlation with insulin resistance (IR)during different stages of gestational diabetes mellitus (GDM). Methods: Thirty-two subjects with GDM and 31 cases of normal pregnant women nonnal glucose tolerance, NGT were enrolled in the study, serum TNF-α and insulin were determined by radioimmunoassay. The plasma glucose was measured by using glucose oxidase. Tests repeated for each group according different stages of prenatal 25-28 weeks, 29-32 weeks, 37-38 weeks and postpartum 6-8 weeks. IR was assessed by the homeostasis model of assessment for insulin resistance index (HOMA-IR). Results: (1)Serum TNF-α levels in CDM and NGT group rose with gestational age, and both significantly decreased at postpartum. (2) Serum TNF-α levels in GDM of above-mentioned four stages respectively were (7.05±0.67) ng/L, (7.11± 0.75) ng/L, (7.36±0.79) ng/L, (5.46±0.37) ng/L respectively. All significantly increased than those in the same stage group (t=7.81, 7.05, 7.15, P<0.01). (3) Maternal serum TNF-α levels were in positive correlation with HOMA-IR in GDM (r=0.571, P<0.05). Conclusions: Serum TNF-α levels in GDM rose with gestational age, but significantly decreased at postpartum. The dynamic changes of serum TNF-α contribute to occurrence of insulin resistance.

2016-05-01

Vascular dysfunction has been described in women with a history of gestational diabetes mellitus. Furthermore, previous gestational diabetes mellitus increases the risk of developing Type 2 diabetes mellitus, a risk factor for cardiovascular disease. Factors contributing to vascular changes remain uncertain. The aim of this review was to summarize vascular structure and function changes found to occur in women with previous gestational diabetes mellitus and to identify factors that contribute to vascular dysfunction. A systematic search of electronic databases yielded 15 publications from 1998 to March 2014 that met the inclusion criteria. Our review confirmed that previous gestational diabetes mellitus contributes to vascular dysfunction, and the most consistent risk factor associated with previous gestational diabetes mellitus and vascular dysfunction was elevated body mass index. Heterogeneity existed across studies in determining the relationship of glycaemic levels and insulin resistance to vascular dysfunction. © The Author(s) 2016.

Iron, Oxidative Stress and Gestational Diabetes

Full Text Available Both iron deficiency and hyperglycemia are highly prevalent globally for pregnant women. Iron supplementation is recommended during pregnancy to control iron deficiency. The purposes of the review are to assess the oxidative effects of iron supplementation and the potential relationship between iron nutrition and gestational diabetes. High doses of iron (~relative to 60 mg or more daily for adult humans can induce lipid peroxidation in vitro and in animal studies. Pharmaceutical doses of iron supplements (e.g., 10× RDA or more for oral supplements or direct iron supplementation via injection or addition to the cell culture medium for a short or long duration will induce DNA damage. Higher heme-iron intake or iron status measured by various biomarkers, especially serum ferritin, might contribute to greater risk of gestational diabetes, which may be mediated by iron oxidative stress though lipid oxidation and/or DNA damage. However, information is lacking about the effect of low dose iron supplementation (≤60 mg daily on lipid peroxidation, DNA damage and gestational diabetes. Randomized trials of low-dose iron supplementation (≤60 mg daily for pregnant women are warranted to test the relationship between iron oxidative stress and insulin resistance/gestational diabetes, especially for iron-replete women.

We compared, in 733 women with gestational diabetes mellitus treated with metformin and/or insulin, rates of neonatal hypoglycaemia in those who had received a dextrose/insulin infusion during labour and prior to delivery (n = 132) with those who did not (n = 601). Women who had infusions were more likely to have been treated with insulin (87.1% vs 70.4%, P < 0.01) and have higher mean capillary glucose values (measured four times daily) in the two weeks prior to delivery (P < 0.01). They had lower mean (SD) glucose values in the 12 h prior to delivery (5.1 (1.1) mmol/L vs 5.4 (0.9) mmol/L, P < 0.01). There was no difference between the groups in rates of neonatal hypoglycaemia (glucose <2.6 mmol/L on two or more occasions), 15.9% versus 17.8%, P = 0.78, or of severe neonatal hypoglycaemia (one or more glucose <1.6 mmol/L), 8.3% versus 5.2%, P = 0.15. In the absence of randomised data comparing use of infusions with no infusions, these data are reassuring for clinicians who do not routinely use infusions. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Potential Mechanisms of Exercise in Gestational Diabetes

Science.gov (United States)

Golbidi, Saeid; Laher, Ismail

2013-01-01

Gestational diabetes mellitus (GDM) is defined as glucose intolerance first diagnosed during pregnancy. This condition shares same array of underlying abnormalities as occurs in diabetes outside of pregnancy, for example, genetic and environmental causes. However, the role of a sedentary lifestyle and/or excess energy intake is more prominent in GDM. Physically active women are less likely to develop GDM and other pregnancy-related diseases. Weight gain in pregnancy causes increased release of adipokines from adipose tissue; many adipokines increase oxidative stress and insulin resistance. Increased intramyocellular lipids also increase cellular oxidative stress with subsequent generation of reactive oxygen species. A well-planned program of exercise is an important component of a healthy lifestyle and, in spite of old myths, is also recommended during pregnancy. This paper briefly reviews the role of adipokines in gestational diabetes and attempts to shed some light on the mechanisms by which exercise can be beneficial as an adjuvant therapy in GDM. In this regard, we discuss the mechanisms by which exercise increases insulin sensitivity, changes adipokine profile levels, and boosts antioxidant mechanisms. PMID:23691290

To investigate the role of visfatin in the pathogenesis of gestational diabetes mellitus (GDM) and its correlation with insulin resistance. The study recruited 58 pregnant women of 24 to 28 gestational weeks in People's Hospital of Hebei Province from January to June 2013. Among them, 30 were patients with GDM (GDM group), 28 had normal oral glucose tolerance test and was referred as healthy pregnancy group (NGT group). Fourteen age-matched female who were first-degree relatives (FDR1) of type 2 diabetes mellitus patients, and 27 healthy nonpregnant women with normal oral glucose tolerance test were referred as high-risk group and normal controls (NC), respectively. The fasting plasma glucose (FPG), 1 hour and 2 hours postprandial glucose levels were measured by glucose oxidase method. The fasting insulin (FIN) levels were measured by radioimmunoassay and the homeostatic model assessment-insulin resistance index (HOMA- IR) was calculated. The levels of total cholesterol (TC), triglycerdes (TG), high density lipoprotein cholesterol (HDL) and low density lipoprotein cholesterol (LDL) were determined. The visfatin levels were measured by ELISA. (1)The levels of FPG were significantly higher in GDM, FDR1 and NC group [(5.5 ± 0.7), (5.1 ±0.6), (5.2 ± 0.4)mmol/L] than that in NGT group [(4.5 ± 0.3) mmol/L], respectively (P 0.05). (5)The visfatin levels in NGT group were negatively correlated to the levels of FPG, HOMA-IR and TC (r = -0.38, -0.44, -0.47, respectively, P 0.05). While in NC group, the levels of visfatin were negatively correlated with FPG and 2 hours postprandial glucose(r = -0.48, -0.42, respectively, P insulin resistance.

The aim of this observational cohort study was to explore concerns, mood state, quality of life (QoL) and treatment satisfaction of women treated for gestational diabetes (GDM). Twenty-seven diet-treated and 18 insulin-treated women participated in a semi-structured interview and completed a series of three different questionnaires. Qualitative analysis identified "the baby's health" as dominant concern, but also as main motivational treatment factor. Treatment satisfaction was generally high and further increased, whereas QoL and mood state significantly dropped over time. Acknowledgment of women's concerns and precise information may improve treatment compliance and outcome.

Full Text Available OBJECTIVE: The aim of this study was to determine the effect of gestational diabetes mellitus (GDM on fetal insulin resistance or β-cell function in Chinese pregnant women with GDM. MEASUREMENTS: Maternal fasting blood and venous cord blood samples (reflecting fetal condition were collected in 65 well-controlled Chinese GDM mothers (only given dietary intervention and 83 control subjects. The insulin, glucose and proinsulin concentrations of both maternal and cord blood samples were measured, and the homeostasis model assessment of insulin resistance (HOMA-IR and the proinsulin-to-insulin ratios (an indicator of fetal β-cell function were calculated in maternal and cord blood respectively. RESULTS: Both maternal and fetal levels of insulin, proinsulin and HOMA-IR but not proinsulin-to-insulin ratios were significantly higher in the GDM group than in the control group (maternal insulin, 24.8 vs. 15.4 µU/mL, P = 0.004, proinsulin, 23.3 vs. 16.2 pmol/L, P = 0.005, and HOMA-IR, 5.5 vs. 3.5, P = 0.041, respectively; fetal: insulin, 15.1 vs. 7.9 µU/mL, P<0.001, proinsulin, 25.8 vs. 15.1 pmol/L, P = 0.015, and HOMA-IR, 2.8 vs. 1.4, P = 0.017, respectively. Fetal HOMA-IR but not proinsulin-to-insulin ratios was significantly correlated to maternal HOMA-IR (r = 0.307, P = 0.019, in the pregnant women with GDM. CONCLUSIONS: Fetal insulin resistance was higher in Chinese pregnant women with GDM than control subjects, and correlated with maternal insulin resistance.

Type 1 diabetes mellitus and oral health are strictly related on a reciprocal basis, and an increased susceptibility to a wide variety of oral diseases is recognised in these patients. The aim of the present study was to establish a relationship between the prevalence of dental caries in Type 1 diabetic patients treated with insulin pump and that of non-diabetic patients. An observational clinical study of analytical and cross-sectional nature was conducted. The sample consisted of 30 adults with diabetes mellitus treated with insulin pump (selected from the Coimbra Hospital and Universitary Centre) and 30 nondiabetic adults (selected from the ones accompanying the diabetic patients). One dentist evaluated all of the patients between January and May of 2015 in the Faculty of Medicine of the University of Coimbra. During the clinical evaluation a case report form adapted to the objectives of the investigation was completed. Data analysis was performed and the significance level was set at 5%. Diabetic patients showed similar levels on the caries and plaque index to non-diabetic patients. There were no statistically significant differences between the two groups as regards oral hygiene habits and frequency of visits to the dentist. Discussão: Although diabetics' diet is less abundant in carbohydrates, which provides a smaller exposure to cariogenic food, the regularity of meals can increase the risk of caries since the critical pH for demineralization is reached frequently throughout the day. However, the existence of a chronic condition may determine a high concern for general preventive care, resulting in an overall improvement of their oral health, which could justify the results. Type 1 diabetic patients treated with insulin pump don't have a higher prevalence of dental caries.

2014-01-01

Oral hypoglycemic agents such as glyburide (second generation sulfonylurea) and metformin (biguanide) are attractive alternatives to insulin due to lower cost, ease of administration, and better patient adherence. The majority of evidence from retrospective and prospective studies suggests comparable efficacy and safety of oral hypoglycemic agents such as glyburide and metformin as compared to insulin when used in the treatment of women with gestational diabetes mellitus (GDM). Glyburide and metformin have altered pharmacokinetics during pregnancy and both agents cross the placenta. In this article, we review the efficacy, safety and dosage of oral hypoglycemic agents for the treatment of gestational diabetes mellitus. Additional research is needed to evaluate optimal dosage for glyburide and metformin during pregnancy. Comparative studies evaluating the effects of glyburide and metformin on long-term maternal and fetal outcomes are also needed. PMID:25315294

The aim of this study was to investigate the relationship between plasma fatty acid binding protein 4 (FABP4), phosphatase and tensin homolog (PTEN), and insulin resistance in patients with gestational diabetes mellitus (GDM). Plasma FABP4 and PTEN were determined by ELISA in GDM patients (GDM group, n=30) and in euglycemic pregnant women (control group, n=30). The clinical features, body mass index (BMI), homeostasis model assessment of insulin resistance (HOMA-IR), and lipid profiles were compared between the 2 groups. The influence of risk factors on insulin resistance, including BMI, lipid profiles, FABP4, and PTEN, were further investigated by multiple-factor stepwise regression analysis. Higher levels of BMI, ΔBMI, triglyceride (TG), fasting plasma glucose (FPG), 2-hour plasma glucose (2hPG), fasting insulin, HOMA-IR, FABP4, PTEN, and lower level of high-density lipoprotein cholesterol (HDL-C) were found in the GDM patients than in the controls (all Pinsulin resistance. GDM patients have more severe insulin resistance compared to euglycemic pregnant women. Higher levels of plasma FABP4 and PTEN are associated with increased insulin resistance and may participate in the pathogenesis of insulin resistance during gestation.

To compare the effects of metformin with insulin on maternal and neonatal outcomes in gestational diabetes mellitus (GDM). A literature search in PUBMED, EMBASE, Science Direct, Springer link, and Cochrane library was conducted using the following search terms: "Gestational Diabetes" or "GDM", and "insulin" and "metformin". Quality assessment of included studies was determined with Quality Assessment of Diagnostic Accuracy Studies. Review Manger 5.2 was used to analyze mean difference (MD)/risk ratio (RR) and 95 % confidence interval (CI) in random-effects model or fixed-effects model depending on the level of heterogeneity. A total of 11 studies were identified. There was no significant difference of the effect on maternal outcomes between the two treatments in glycohemoglobin A1c levels (P = 0.37), fasting blood glucose (P = 0.66), and the incidence of preeclampsia (P = 0.26); whereas, significantly reduced results were found in the metformin group in pregnancy-induced hypertension (PIH) rate (RR = 0.53, 95 % CI 0.31-0.90, P = 0.02), average weight gains after enrollment (MD = -1.28, 95 % CI -1.54 to -1.01, P metformin presented significantly lower average birth weights (MD = -44.35, 95 % CI -85.79 to -2.90, P = 0.04), incidence of hypoglycemia (RR = 0.69, 95 % CI 0.55-0.87, P = 0.001) and neonatal intensive care unit (NICU) (RR = 0.82, 95 % CI 0.67-0.99, P = 0.04). Metformin can significantly reduce several adverse maternal and neonatal outcomes including PIH rate, incidence of hypoglycemia and NICU, thus it may be an effective and safe alternative or additional treatment to insulin for GDM women.

Full Text Available The aim of the present study was to evaluate the levels of pro-insulin and pro-insulin/ insulin ratio (PIR in pregnant with normal glucose tolerance (NGT, pregnant with gestational diabetes mellitus (GDM and women after delivery with GDM history. Normal pregnancy is characterized by progressive insulin resistance, which is physiologically compensated by an increase in insulin secretion. The higher secretion of the insulin precursor pro-insulin has been associated with β-cell dysfunction. A total of 102 pregnant women between 24-28 gestational weeks (53 GDM pregnant, 49 with NGT and 22 postpartum with GDM history, as assessed by a 2h oral glucose tolerance test, were included in the study. Fasting plasma insulin and pro-insulin (PI concentrations at the basal state were measured in all women. The ratio pro-insulin/insulin was calculated. BMI was significantly higher in GDM pregnant compared to NGT weight-matched group (30.56 ± 6.9 vs. 30.56 ± 6.9; p < 0, 011 and compared to the levels after delivery (30.56 ± 6.9vs. 27.9 ± 6, 27; p < 0, 001. Significant differences in the levels of PI between NGT and GDM pregnant (3.94 ± 2.78 vs. 7.59 ± 5.27; p = 0.006, between GDM and postpartum women (7.59 ± 5.27 vs. 4.46 ± 1.14; p = 0.022 were established. No signifi cant difference in the level of PIR between two pregnant groups was observed. Separately NGT and GDM showed signifi cant difference compared to young mothers (0.41 ± 0.14 vs. 0.148 ± 0.031, p < 0.02; 0.46 ± 0.16 vs. 0.148 ± 0.031, p = 0.009.

2018-04-01

Full Text Available We report a case of a woman with diabetes mellitus caused by a genetic defect in ABCC8-coding sulfonylurea receptor 1 (SUR1, a subunit of the ATP-sensitive potassium (KATP channel protein. She was diagnosed with diabetes at 7 days after birth. After intravenous insulin drip for 1 month, her hyperglycaemia remitted. At the age of 13 years, her diabetes relapsed, and after that she had been treated by intensive insulin therapy for 25 years with relatively poor glycaemic control. She was switched to oral sulfonylurea therapy and attained euglycaemia. In addition, her insulin secretory capacity was ameliorated gradually.

Full Text Available Introduction and objective. Gestational diabetes mellitus (GDM is a pregnancy complication which increases the risk for maternal and foetal complications during pregnancy, and also significantly increases the cardiovascular risk for women’s health in the postpartum. Current literature provides contradictory information on the role of adiponectin (AdipoQ in the course of GDM. The aim of the study was to measure AdipoQ concentration in blood of women with GDM and to find correlations between this adipokine and clinical and biochemical parameters of the atherogenic risk. Material and methods. The GDM group included 50 women diagnosed with GDM between 24 – 28 weeks of gestation who underwent routine prenatal tests for GDM in compliance with the guidelines of the Polish Diabetes Association. All patients underwent clinical and laboratory evaluation at GDM diagnosis. Laboratory tests included serum AdipoQ concentration, fasting glucose and insulin, OGTT, lipid parameters, C-reactive protein and fibrinogen in serum. Results. The GDM group showed significantly elevated fasting glucose, insulin, HOMA-IR values, total cholesterol, LDLcholesterol and triglicerydes as compared with the control group (p<0.05. The atherogenic index, CRP, fibrinogen in women with GDM were significantly higher than in the control group (p<0.05. AdipoQ concentrations did not differ significantly between the groups during gestation (p=0.7054. No correlations, except with the neonatal weight (r= – 0.29, p<0.05, were found between AdipoQ and the studied parameters. Conclusions. Based on the conducted studies, it may be conclude that women with early diagnosed and promptly treated GDM have a normal adiponectin level, although insulin resistant changes and increased cardiovascular risk in basic metabolic parameters are observed. Moreover, adiponectin does not reflect the atherogenic risk in pregnant women with GDM.

To examine whether the reduced incidence of preeclampsia in non-diabetic obese pregnant women treated with metformin is mediated by changes in insulin resistance. This was a secondary analysis of obese pregnant women in a randomised trial (MOP trial). Fasting plasma glucose and insulin were measured in 384 of the 400 women who participated in the MOP trial. Homeostasis model assessment of insulin resistance (HOMA-IR) was compared in the metformin and placebo groups and in those that developed preeclampsia versus those that did not develop preeclampsia. At 28 weeks, median HOMA-IR was significantly lower in the metformin group. Logistic regression analysis demonstrated that there was a significant contribution in the prediction of preeclampsia from maternal history of chronic hypertension and gestational weight gain, but not HOMA-IR either at randomisation ( p  = 0.514) or at 28 weeks ( p  = 0.643). Reduced incidence of preeclampsia in non-diabetic obese pregnant women treated with metformin is unlikely to be due to changes in insulin resistance.

Women with gestational diabetes mellitus (GDM) are at an increased risk for developing metabolic syndrome, type 2 diabetes mellitus (T2DM), and cardiovascular disease. In this review, we will discuss postpartum cardiovascular and diabetes risk in women with a history of GDM and different ways to improve postpartum screening. This review involves a comprehensive literature review on gestational diabetes and postpartum risk for cardiovascular disease and diabetes mellitus as well as post-partum screening methods. Cardiovascular risk post-partum is potentiated by increased inflammatory markers leading to worsening atherosclerosis and cardiovascular events downstream. Decreased insulin sensitivity and β cell compensation, recurrent GDM, maternal factors such as pre and post-partum weight gain and lactation may contribute to T2DM risk. Postpartum glucose testing is essential in screening women as hyperglycemia in pregnancy has long term effects on both cardiovascular disease and diabetes risk on the mother. Long and short term improvement to post-partum glucose testing is essential to decreasing cardiometabolic and diabetes risk in women with gestational diabetes mellitus.

Gestational diabetes mellitus (GDM) is associated with high birth weight in the offspring. This may lead to overweight and insulin resistance during childhood. The aim of the study was to assess the impact of GDM on overweight risk and insulin resistance in offspring. BMI measurements were collected at age 2, 8, and 11 years from 232 offspring of mothers with GDM (OGDM) and compared with those from 757 offspring of mothers with type 1 diabetes (OT1D) and 431 offspring of nondiabetic mothers (ONDM) born between 1989 and 2000. Insulin resistance (homeostasis model assessment of insulin resistance [HOMA-IR]) was determined at age 8 and 11 years in 751 children (74 OGDM). Overweight was defined as BMI percentile >or=90; insulin resistance was defined by HOMA-IR. Overweight prevalence was increased in OGDM compared with OT1D and to ONDM throughout childhood (age 11 years 31.1, 15.8, and 15.5%; P = 0.005). Maternal obesity was an important predictor of overweight risk in children (age 11 years odds ratio 7.0 [95% CI 1.8-27.7]; P = 0.006); birth size and maternal smoking during pregnancy were inconsistently associated with and treatment of GDM during pregnancy did not affect overweight risk. HOMA-IR was increased in OGDM compared with offspring of ONDM mothers (P = 0.01, adjusted for sex and age) and was associated with the child's BMI (P = 0.004). Overweight and insulin resistance in children is increased in OGDM compared with OT1D or ONDM. The finding that overweight risk is associated mainly with maternal obesity suggests that familial predisposition contributes to childhood growth in these offspring.

Gestational diabetes mellitus (GDM) has a higher incidence of neonatal respiratory distress syndrome, and lipogenesis is required for the synthesis of pulmonary surfactants. The aim of this study was to determine the effect of insulin treatment in GDM on the production of lipids in the lungs of fetal rats. GDM was induced by streptozotocin, and insulin was used to manage diabetes. Type II alveolar epithelial cells (AEC II), bronchoalveolar lavage fluid (BALF), and lung tissues of the neonatal rats were sampled for analyses. Insulin treatment could not decrease plasma glucose to normal level at a later gestational stage. Lipids/phospholipids in AEC II, BALF, and lung tissues decreased in GDM, and insulin treatment could not increase the levels; quantitative PCR and western blotting demonstrated a lower level of sterol regulator element-binding protein 1 (SREBP-1), SREBP cleavage-activating protein (SCAP), and insulin-induced gene 1 (INSIG-1) in GDM, but insulin treatment upregulated only SREBP-1. Nuclear translocation of the SREBP-1 protein in AEC II was impaired in GDM, which could not be ameliorated by insulin treatment. These findings indicated that insulin treatment in GDM cannot promote lipogenesis in the fetal lung because of failure to redress the imbalance among SREBP-1, SCAP, and INSIG-1.

Gestational diabetes mellitus (GDM) is a metabolically complex disease with major genetic determinants. GDM has been associated with insulin resistance and dysfunction of pancreatic beta cells, so the GDM candidate genes are those that encode proteins modulating the function and secretion of insulin, such as that for calpain 10 (CAPN10). This study aimed to assess whether single nucleotide polymorphism (SNP)-43, SNP-44, SNP-63, and the indel-19 variant, and specific haplotypes of the CAPN10 gene were associated with gestational diabetes mellitus. We studied 116 patients with gestational diabetes mellitus and 83 women with normal glucose tolerance. Measurements of anthropometric and biochemical parameters were performed. SNP-43, SNP-44, and SNP-63 were identified by polymerase chain reaction (PCR)-restriction fragment length polymorphisms, while the indel-19 variant was detected by TaqMan qPCR assays.  The allele, genotype, and haplotype frequencies of the four variants did not differ significantly between women with gestational diabetes mellitus and controls. However, in women with gestational diabetes mellitus, glucose levels were significantly higher bearing the 3R/3R genotype than in carriers of the 3R/2R genotype of the indel-19 variant (p = 0.006). In conclusion, the 3R/3R genotype of the indel-19 variant of the CAPN-10 gene influenced increased glucose levels in these Mexican women with gestational diabetes mellitus.

Type 1 diabetes mellitus is an autoimmune disease resulting from the destruction of pancreatic β cells. Current treatments for patients with type 1 diabetes mellitus include daily insulin injections or whole pancreas transplant, each of which are associated with profound drawbacks. Insulin gene therapy, which has shown great efficacy in correcting hyperglycemia in animal models, holds great promise as an alternative strategy to treat type 1 diabetes mellitus in humans. Insulin gene therapy refers to the targeted expression of insulin in non-β cells, with hepatocytes emerging as the primary therapeutic target. In this review, we present an overview of the current state of insulin gene therapy to treat type 1 diabetes mellitus, including the need for an alternative therapy, important features dictating the success of the therapy, and current obstacles preventing the translation of this treatment option to a clinical setting. In so doing, we hope to shed light on insulin gene therapy as a viable option to treat type 1 diabetes mellitus.

Full Text Available Gestational diabetes mellitus (GDM is a common complication of pregnancy, and it is mostly associated with postpartum diabetes, insulin resistance, and dyslipidemia. Fish oil (omega-3 supplementation has been shown to reduce the risk of different chronic diseases such as cardiovascular disease, type 2 diabetes, and cancers, though the evidence of its impact on gestational diabetes is scarce. Our goal in this study was to determine the effect of fish oil administration on gene expression related to insulin action, blood lipids, and inflammation in women with GDM. Participants with GDM (n = 40, aged 18–40 years, were randomized to take either 1000 mg fish oil capsules, containing 180 mg eicosapentaenoic acid and 120 mg docosahexaenoic acid (n = 20, or placebo (n = 20 twice a day for 6 weeks. Gene expression related to insulin, lipids, and inflammation was quantified in peripheral blood mononuclear cells (PBMCs of GDM women using Reverse Transcription Polymerase Chain Reaction (RT-PCR method. Results of RT-PCR indicated that omega-3 supplementation upregulated gene expression of peroxisome proliferator-activated receptor gamma (PPAR-γ (P = 0.04 in PBMCs of patients with GDM, compared with the placebo. In addition, gene expression of the low-density lipoprotein receptor (LDLR (P < 0.001, interleukin-1 (IL-1 (P = 0.007, and tumor necrosis factor alpha (TNF-α (P = 0.01 was downregulated in PBMCs of women with GDM, following omega-3 supplementation. No significant effect of omega-3 supplementation was indicated on gene expression of IL-8 in PBMCs of patients with GDM. Overall, fish oil supplementation for 6 weeks in women with GDM significantly improved gene expression of PPAR-γ, IL-1, and TNF-α, but not gene expression of IL-8.

We examined the association between socio-demographic marginalization and plasma glucose levels at diagnosis of gestational diabetes in a multi-ethnic and socio-economically diverse patient group. Medical charts at a Toronto gestational diabetes clinic were reviewed for women with a recorded pregnancy between 1 March 2006 and 26 April 2011. One-hour 50-g glucose challenge test values and postal code data were abstracted. Postal codes were merged with 2006 Canadian census data to compute neighbourhood-level ethnic concentration (% recent immigrants, % visible minorities) and material deprivation (% low education, % low income, single-parent households). We compared women in the highest neighbourhood quintiles for both ethnic concentration and material deprivation with all other women to explore an association between marginalization and diagnostic glucose levels. Multivariate regression models of glucose challenge test values and insulin prescription were adjusted for age, prior gestational diabetes, parity and diabetes family history. Among 531 patients with complete glucose challenge test data (mean 11.94 mmol/l, sd 1.83), those in the most marginalized neighbourhoods had 0.43 mmol/l higher glucose challenge test values (95% CI 0.08-0.78) compared with the rest of the study population. Other factors associated with higher glucose challenge test values were prior gestational diabetes (0.59 mmol/l increment, 95% CI 0.19-0.99) and diabetes family history (0.32 mmol/l increment, 95% CI -0.01 to 0.66). Each additional 1 mmol/l glucose challenge test result was associated with an increased likelihood of being prescribed insulin (odds ratio 1.33, 95% CI 1.17-1.51). Women living in the most materially deprived and ethnically concentrated neighbourhoods have higher glucose levels at diagnosis of gestational diabetes. They may need close monitoring for timely initiation of insulin. © 2014 The Authors. Diabetic Medicine © 2014 Diabetes UK.

Recent data indicate that serum Hsp70 (HSPA1A) levels are increased in type 1 and 2 diabetes mellitus. However, there is no report in the literature on circulating Hsp70 levels in gestational diabetes mellitus. In this pilot study, we measured serum Hsp70 levels in 11 pregnant women with pregestational diabetes, 38 women with gestational diabetes, and 40 healthy pregnant women with ELISA. Plasma glucose levels, serum insulin concentrations, HbA1c values, and the Homeostatic Model Assessment-Insulin Resistance (HOMA-IR) index were also determined. According to our results, serum Hsp70 concentrations were significantly higher in women with pregestational and gestational diabetes mellitus than in healthy pregnant women. In addition, pregestational diabetic women had significantly higher Hsp70 levels than those with gestational diabetes. Furthermore, in the group of women with gestational diabetes mellitus, serum Hsp70 levels showed a significant positive correlation with HbA1c values. However, there was no other relationship between clinical features and metabolic parameters of the study subjects and their serum Hsp70 levels in either study group. In conclusion, we demonstrated for the first time in the literature that serum Hsp70 levels are increased and correlate with HbA1c values in women with gestational diabetes mellitus. Nevertheless, further studies are needed to determine whether circulating Hsp70 plays a causative role in the pathogenesis of gestational diabetes or elevated serum Hsp70 levels are only consequences of the disease.

Gestational diabetes mellitus: the effects of diagnosis time and implementation of diabetic care on management of glycemia

Directory of Open Access Journals (Sweden)

2014-06-01

Full Text Available Introduction : Pregnancy is considered diabetogenic condition related to increased requirements for insulin, its increased secretion and ongoing insulin resistance. In pregnancy increased insulin secretion cannot compensate increased requirements which leads to gestational diabetes mellitus (GDM. If diagnosed too late or ill-treated diabetes can cause serious complications in the course of pregnancy and delivery as well as late complications in neonate. Aim of the research: To assess if time of diagnosis of gestational diabetes mellitus and implementation of diabetic care influence glycemia management and clinical condition of neonate after birth. Material and methods: The survey was carried out in the group of 300 pregnant women with GDM. The patients were divided into 3 groups: group A – patients with GDM diagnosed between 10–12 week hbd, group B – patients who had GDM diagnosed between 24–28 week hbd and group C – GDM diagnosed between 29 week hbd and delivery. Results: The analysis revealed correlation between the frequency of GDM and patient’s age and body mass index. Time of GDM diagnosis and following recommendations for GDM management depend on patient’s place of living and socio-economic status. Neonate’s condition is affected by proper glycemia management. Conclusions: There is a correlation between place of living, poor socio-economic status and managing glycemia, which should contribute to developing effective methods of care for women living in those areas. Patients’ body mass index significantly correlated with fetus macrosomy, which significantly affected the way pregnancy was terminated and neonate’s condition after birth. Time of GDM diagnosis has a big influence on glycemia management which is essential for mother’s and neonate’s health.

Gestational diabetes mellitus (GDM) is a condition that affects increasing number of pregnant women worldwide. Sitagliptin was reported to alleviate symptoms of type 2 diabetes mellitus by reducing serum levels of retinol-binding protein 4 (RBP-4). We investigated the effectiveness of sitagliptin on insulin sensitivity parameters in GDM patients. Pregnant GDM women in the 2nd trimester were recruited for this study. Participants were then assigned randomly to sitagliptin treatment group or placebo treatment group, and administered sitagliptin or placebo daily for 16 weeks. Glucose and insulin profiles, as well as serum RBP-4 level, were measured at both baseline and end of the study. After 16 weeks of treatment, participants in the STL group exhibited significantly improved levels of fasting plasma glucose and serum insulin, homeostasis model of assessment of β cell function (HOMA-β) and insulin resistance (HOMA-IR), compared with those in the placebo group. Serum levels of RBP-4 were also markedly decreased in the sitagliptin treatment group, and more importantly it was positively correlated with improved insulin resistance parameters. Our study supports a potentially promising role of sitagliptin in improving insulin resistance by decreasing RBP-4 in GDM-affected women.

Per Glud Ovesen

2018-01-01

Full Text Available Background. The prevalence of gestational diabetes (GDM is increasing worldwide. The most important risk of GDM in pregnancy is excessive fetal growth, increasing the risk of complications during delivery as well as long-term complications like obesity and diabetes in both the mother and the offspring. Method. All women with GDM who delivered a singleton between 2004 and 2016 were included. The treatment of GDM patients sought to achieve normal blood glucose levels, primarily by diet and exercise. If the glycemic targets were not reached, insulin therapy was initiated. Birth weight and birth weight Z-score was calculated corrected for gender and gestational age at delivery. Results. The study included 1910 women. The number of GDM women increased significantly each year over the course of the study, as did the proportion requiring insulin therapy. Birth weight and birth weight Z-score fell significantly over the years largely due to a decrease in large for gestational age frequency from 29% to around 19%. Conclusion. During the last 13 years, the number of women diagnosed with GDM has increased. Furthermore, the proportion of GDM women receiving insulin treatment has increased. The birth weight in diet-treated women has been virtually normal for the last 5 years of the reported period.

We aimed to compare changes in insulin levels during an oral glucose tolerance test (OGTT) between women with normal glucose tolerance (NGT) during pregnancy and those with gestational diabetes mellitus (GDM). Overall, 105 pregnant women between 24 and 28 weeks' gestation, 50 with NGT and 55 with GDM according to NDDG standard, were enrolled into the study. The levels of fasting blood glucose, insulin, triglyceride (TG) and total cholesterol (TC) and the insulin levels, blood glucose levels at 1, 2 and 3 hours post oral glucose administration during an OGTT (5.8, 10.6, 9.2 and 8.1 mmol/L, respectively) were measured. Then, insulin resistance (IR) index was calculated. There was no significant difference in fasting, 3-h insulin levels and 3-h blood glucose levels between those with NGT and those with GDM (P > 0.05). However, 1-h and 2-h insulin levels, fasting and 1-h and 2-h blood glucose levels in women with GDM were significantly higher than those in the NGT group (P < 0.05). Fasting TC and TG levels in the GDM group were significantly higher than those with NGT (P = 0.031 and P = 0.025, respectively). Correlation analysis showed that TG and TC levels were positively correlated with homoeostasis model assessment-IR (HOMA-IR) (r = 0.67 and r = 0.78, respectively; P < 0.05). Our findings suggest that insulin sensitivity in women with GDM was significantly lower than that observed in those with NGT. Reducing IR and blood lipids in women with GDM could potentially improve maternal and foetal outcomes.

Gestational diabetes mellitus, most of which progress to type-2 diabetes mellitus is increasing worldwide. Identification of gestational diabetes and control of glucose can reduce such complications and improve maternal and neonatal health. A hospital based cross sectional study was conducted to find out maternal and fetal outcome of gestational diabetes from January to July 2011. Data were collected from 109 gestational diabetes mothers attending Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders (BIRDEM) hospital for delivery. Study revealed that gestational diabetes was more common among mothers aged >25 years old and multiparaous women. Mean gestational age of diagnosis was 16.82±9.54 weeks. Sixty eight (68%) mothers were diagnosed before 20 weeks of gestation and more than 90% mothers with gestational diabetes delivered by caesarean section. Mean pregnancy weight gain was 6.8±1.18kg. Adverse maternal outcome observed in 24% cases and adverse fetal outcome was present in 34% cases. In univariate analysis weeks of delivery and fasting blood sugar were statistically significantly associated with adverse pregnancy outcome. Babies born to mothers with only diet restriction had less birth weight than mothers with insulin therapy. Pregnancy thought to be the most vulnerable stage of women's life and protecting her health along with her fetus during this period yields a positive impact on the health of future generation. Particular attention should be given during antenatal period to initiate screening programme and treatment protocol for gestational diabetic mothers.

To determine what proportion of women with gestational diabetes underestimate their diabetes risk and identify factors associated with low diabetes risk perception. Participants included pregnant adult women with gestational diabetes between 2009 and 2012 across seven diabetes clinics in Ontario, Canada. Data were collected through chart review and a survey that included a diabetes risk perception question. Of the 614 of 902 women (68% response rate) with gestational diabetes, 89% correctly responded that gestational diabetes increases the risk for developing diabetes. However, 47.1% of women perceived themselves to be at low risk for developing diabetes within 10 years. On multivariable analysis, BMI gestational diabetes history, absent diabetes family history and absent insulin use were appropriately associated with low diabetes risk perception. However, compared with Caucasian ethnicity, high-risk ethnicity (Aboriginal, Latin American, West Indian, South Asian, Middle Eastern, Filipino, Black, Pacific Islander) [odds ratio (OR) 2.07; 95% CI 1.30-3.31] and East and South East Asian ethnicity (OR 2.01; 1.10-3.67) were associated with low diabetes risk perception. After further adjustment for immigration, only high-risk ethnicity remained a predictor of low diabetes risk perception (OR 1.86; 1.09-3.19), whereas East and South East Asian ethnicity did not (OR 1.67; 0.86-3.22). Although the majority of women recognized gestational diabetes as a risk factor for diabetes, almost half underestimated their personal high diabetes risk despite prenatal care. Furthermore, women from high-risk ethnic groups were more likely to underestimate their risk, even after adjusting for immigration. Interventions tailored to these groups are necessary to enhance perceived diabetes risk. © 2015 Diabetes UK.

Fifty-six pregnant women with gestational diabetes mellitus (GDM) and 42 normal glucose tolerant (NGT) pregnant women between 26 and 36 gestational weeks were included in the study prospectively. The body fat percentage (BFP) was calculated using the Siri formula from skinfold thickness (SFT) measurements. Both groups were comparable for gestational age, height, weight, and body mass index (P>.05). Insulin resistance assessed by homeostasis model assessment for insulin resistance (HOMA-IR) method was significantly higher in GDM patients compared to their NGT weight-matched control group. In contrast, the insulin sensitivity calculated from quantitative insulin sensitivity check index (QUICKI-IS) equation was significantly lower in GDM group. Calculated lean body mass was found to be similar in between both groups. Body fat percentage derived from SFT parameters was significantly higher in women with GDM. Women with GDM had significantly higher levels of serum insulin and leptin concentrations when compared with the NGT group. All SFT measurements were higher in GDM group when compared to those in NGT women. We did not find any correlation between leptin levels and insulin resistance; we found negative correlation between leptin levels and insulin sensitivity. Thus, we observed that leptin may contribute development of GDM by decreasing insulin sensitivity but not increasing insulin resistance. Also, we observed that the BFP estimated by the Siri formula from SFT measurements correlated significantly with HOMA-IR and QUICKI-IS and leptin concentrations in pregnant women. We suggest that by simply evaluating SFT, we may hold a view about BFP and leptin concentrations and insulin sensitivity in pregnant women.

Diabetes results in a rise in blood glucose above normal physiological levels; if untreated this may cause damage to many systems including the cardiovascular and renal systems. Pregnancy increases resistance to insulin action; for those women who have pre-gestational diabetes, this results in an increasing insulin requirement. There are several methods of administering insulin. Conventionally, insulin has been administered subcutaneously, formally referred to as intensive conventional treatment, but now more usually referred to as multiple daily injections (MDI). An alternative method of insulin administration is the continuous subcutaneous insulin infusion pump (CSII). To compare CSII with MDI of insulin for pregnant women with pre-existing and gestational diabetes. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 March 2016) and reference lists of retrieved studies. Randomised trials comparing CSII with MDI for pregnant women with diabetes. Three review authors independently assessed studies and two review authors extracted data. Disagreements were resolved through discussion with the third author. We assessed the quality of the evidence using the GRADE approach. We included five single-centre trials (undertaken in Italy) with 153 women and 154 pregnancies in this review.There were no clear differences in the primary outcomes reported between CSII and MDI in the included trials: caesarean section (risk ratio (RR) 1.09, 95% confidence interval (CI) 0.66 to 1.77; three trials, 71 women, evidence graded very low), large-for-gestational age (RR 4.15, 95% CI 0.49 to 34.95; three trials, 73 infants; evidence graded very low), and perinatal mortality (RR 2.33, 95% CI 0.38 to 14.32; four trials, 83 infants, evidence graded very low). Other primary outcomes were not reported in these trials (hypertensive disorders of pregnancy, development of type 2 diabetes, composite outcome of serious neonatal outcomes, and neurosensory disability

This study assessed whether myoinositol might be a first-line medical treatment for gestational diabetes mellitus (GDM). For 12 months, women with GDM not controlled by diet (n=32) were prospectively treated with myoinositol 1200mg and folic acid 400μg/day, while consecutive women (n=28) with insulin-requiring GDM treated during the previous year at our centre constituted the control group. Baseline characteristics and care were similar in both groups. Insulin was required in eight women (25%) in the myoinositol group who, compared with the 24 who did not need insulin, were older (37±5 vs. 32±5 years, respectively; P=0.018) and had a larger percentage of high self-monitored glucose values (45±8% vs. 32±14%; P<0.0001) during the week prior to the introduction of myoinositol treatment. All of the women had similar pregnancy outcomes regardless of their GDM management, although less labour induction was required in the myoinositol group (OR: 0.22 [0.07-0.65]), which had no side effects. This pilot study suggests that myoinositol may be a safe first-line medical treatment for uncontrolled GDM. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

To evaluate glycemic control among women with gestational diabetes mellitus (GDM) under insulin versus metformin (with or without insulin supplementation), and to identify metformin poor responders requiring supplemental insulin. In Ain Shams University Hospital, mothers with 26-32-week GDM pregnancies, failing diet control, were randomized to receive metformin (n = 47) or insulin (n = 48). The primary outcome was glycemic control. Secondary outcomes included maternal weight, parameters predicting successful metformin monotherapy, neonatal hypoglycemia, and birthweight. Women using metformin (23.4% needing supplemental insulin) gained less weight (P metformin group was related to initial body mass index, HbA1c, oral glucose tolerance test (GTT), and first week mean glucose level. The 1-h glucose level during initial GTT (Hr1-GTT) and the mean fasting glucose level during the first week of therapy (Wk1-mFG) were the two independent parameters associated with requiring supplemental insulin. Women with Hr1-GTT >212 mg/dL and Wk1-mFG >95 mg/dL had a risk ratio of 58.6 (95%CI: 3.68-933.35, P = 0.004) and 11.5 (95%CI: 2.77-47.34,= 0.0008), respectively for needing supplemental insulin during the course of the study compared with women without. Metformin is an effective and safe alternative to insulin in GDM. Women using metformin (± supplemental insulin) had similar glycemic control, less weight gain, and similar rates of side-effects as those on insulin monotherapy. Insulin supplementation to metformin therapy was more likely with elevated Hr1-GTT and Wk1-mFG. © 2016 Japan Society of Obstetrics and Gynecology.

Full Text Available Objective: Women with insulin-requiring gestational diabetes mellitus (GDM are at high risk of developing diabetes within a few years postpartum. We implemented this phase II study to test the hypothesis that vildagliptin, a dipeptidyl peptidase-4 inhibitor, is superior to placebo in terms of reducing the risk of postpartum diabetes. Methods: Women with insulin-requiring GDM were randomized to either placebo or 50 mg vildagliptin twice daily for 24 months followed by a 12-month observation period (EudraCT: 2007-000634-39. Both groups received lifestyle counseling. The primary efficacy outcomes were the diagnosis of diabetes (American Diabetes Association (ADA criteria or impaired fasting glucose (IFG/impaired glucose tolerance (IGT. Results: Between 2008 and 2015, 113 patients (58 vildagliptin, 55 placebo were randomized within 2.2–10.4 (median 8.6 months after delivery. At the interim analysis, nine diabetic events and 28 IFG/IGT events had occurred. Fifty-two women withdrew before completing the treatment phase. Because of the low diabetes rate, the study was terminated. Lifestyle adherence was similar in both groups. At 24 months, the cumulative probability of postpartum diabetes was 3% and 5% (hazard ratio: 1.03; 95% confidence interval: 0.15–7.36 and IFG/IGT was 43% and 22% (hazard ratio: 0.55; 95% confidence interval: 0.26–1.19 in the placebo and vildagliptin groups, respectively. Vildagliptin was well tolerated with no unexpected adverse events. Conclusions: The study did not show significant superiority of vildagliptin over placebo in terms of reducing the risk of postpartum diabetes. However, treatment was safe and suggested some improvements in glycemic control, insulin resistance, and β-cell function. The study identified critical issues in performing clinical trials in the early postpartum period in women with GDM hampering efficacy assessments. With this knowledge, we have set a basis for which properly powered trials could

Full Text Available Gestational diabetes mellitus (GDM is common in pregnancy. Epidemiological studies have described the prevalence of GDM in the antenatal period, but do not assess the number of women who require pharmacological therapy at term. This information is important for obstetric care providers and health planners. We reviewed indoor charts of all women admitted for delivery at a maternity center in Karnal, Haryana, India. Of the 569 participants, 0.87% had preexisting diabetes, while 1.93% were being treated with drugs for GDM (0.70% insulin, 1.23% metformin. The overall prevalence of diabetes needing drug therapy at time of delivery in pregnant women was 2.81%.

Postprandial plasma glucose excursions and plasma levels of free insulin after subcutaneous bolus injection of a rapidly absorbed monomeric insulin analogue (B9AspB27Glu) or soluble human insulin ('Actrapid HM' U100) were studied in six insulin-treated diabetic subjects. 10 U actrapid or an equimolar amount of the analogue were injected, in random order with an interval of 1 week, immediately before a 500 kcal test meal. Basal insulin levels were similar on the 2 study days (mean 74.1 [SE 5.1] pmol/l, actrapid; 79.7 [13.0] pmol/l, analogue). After injection of actrapid plasma free insulin levels rose slowly, reaching a plateau by 105 min at 222 (19) pmol/l. Injection of the analogue resulted in a rapid early peak at 30 min (798 [112] pmol/l), and levels were significantly higher than those after actrapid between 15 and 210 min. The more physiological plasma insulin levels achieved with the analogue were accompanied by a substantial reduction in postprandial plasma glucose excursions; the integrated area under the incremental plasma glucose curve was 45% lower after the analogue than after actrapid.

Various plant species have long been used in traditional medicine worldwide to treat diabetes. Among the plant-based compounds with hypoglycemic properties, studies on insulin-like proteins isolated from leaves, fruits and seeds are rarely reported in the relevant literature. Our research group has been investigating the presence of insulin-like proteins in Moringa oleifera, a plant species native to India, and we have obtained a leaf protein isolate and semi-purified derived fractions, as well as a seed coat protein fraction (Mo-SC), with hypoglycemic activity in chemically induced diabetic mice that have increased tolerance to orally administered glucose. Equally importantly, Mo-SC possesses insulin-like antigenic epitopes. In this context, the present review aims to highlight that prospection of insulin-like proteins in plants is of the utmost importance both for finding new drugs for the treatment of diabetes and for shedding light on the mechanisms involved in diabetes.

Gestational diabetes mellitus is one of the most common complications of pregnancy. Women with Gestational diabetes are at increased risk of serious health outcomes, such as pre-eclampsia, obstructed labor, and the development of Type 2 diabetes later in life. Chinese migrants, the third largest cultural group in Australia, are more likely to develop Gestational diabetes than Australian-born women. However, to date, Gestational diabetes self-management has not been investigated in this population. To explore the understanding and self-management experiences of Gestational diabetes among Chinese migrants. Data were collected through individual semi-structured face-to-face interviews. Participants were recruited from the antenatal clinic at the Royal Prince Alfred Hospital. Interviews were audio-recorded, transcribed verbatim and thematically analyzed. Although the majority of participants demonstrated a good understanding of Gestational diabetes, some did not understand the principles behind healthcare advice and faced challenges in self-management. Confusion about self-monitoring of blood glucose and fear of insulin were also evident. Participants relied on both formal and informal sources of information. Some had difficulty obtaining adequate support. Cultural influences on self-management included meeting family needs, Chinese diet and use of Chinese medicines. To assist Chinese women with Gestational diabetes to better self-manage their condition, there is a need for clinicians to: (1) provide more effective diabetes education to ensure clear understanding of self-management principles; (2) actively elicit and respond to women's confusion and concerns; (3) provide women with adequate practical support; and (4) develop greater cultural awareness.

To evaluate whether treatment of mild gestational diabetes mellitus (GDM) confers sustained offspring health benefits, including a lower frequency of obesity. Follow-up study of children (ages 5-10) of women enrolled in a multicenter trial of treatment versus no treatment of mild GDM. Height, weight, blood pressure, waist circumference, fasting glucose, fasting insulin, triglycerides, and HDL cholesterol were measured. Five hundred of 905 eligible offspring (55%) were enrolled. Maternal baseline characteristics were similar between the follow-up treated and untreated groups. The frequencies of BMI ≥95th (20.8% and 22.9%) and 85th (32.6% and 38.6%) percentiles were not significantly different in treated versus untreated offspring (P = 0.69 and P = 0.26). No associations were observed for BMI z score, log waist circumference, log triglycerides, HDL cholesterol, blood pressure, or log HOMA-estimated insulin resistance (HOMA-IR). The effect of treatment was different by sex for fasting glucose and log HOMA-IR (P for interaction = 0.002 and 0.02, respectively) but not by age-group (5-6 and 7-10 years) for any outcomes. Female offspring of treated women had significantly lower fasting glucose levels. Although treatment for mild GDM has been associated with neonatal benefits, no reduction in childhood obesity or metabolic dysfunction in the offspring of treated women was found. However, only female offspring of women treated for mild GDM had lower fasting glucose. © 2015 by the American Diabetes Association.

The relationship between tyrosine phosphorylation (TP) and protein expression of insulin receptor (InsR) and insulin resistance (IR) in patients with gestational diabetes mellitus (GDM) was investigated. The InsR expression and TP in skeleton muscle tissue were determined by Western blotting and immunoprecipitation in women with GDM (GDM group, n=22), normal pregnant women (normal pregnancy group, n=22) and normal non-pregnant women (normal non-pregnant group, n=13). Fasting plasma glucose (FPG) and fasting insulin (FINS) were measured by oxidase assay and immunoradioassay. The results showed that the levels of FPG (5.61±0.78 mmol/L), FINS (15.42±5.13 mU/L) and Homeostasis model assessment-IR (HOMA-IR) (1.21±0.52) in GDM group were significantly higher than those in normal pregnancy group (4.43±0.46 mmol/L, 10.56±3.07 mU/L and 0.80±0.31 respectively) (Ppregnant group (7.56±2.31 mU/L and 0.47±0.26 respectively) (P0.05). TP of InsR with insulin stimulation was significantly decreased in GDM group (0.20±0.05) as compared with normal pregnancy group (0.26±0.06) (Pinsulin stimulation in normal pregnancy group was lower than that in normal non-pregnant group (0.31±0.06) (Pinsulin stimulation was negatively related with HOMA-IR in GDM group (r=-0.525, P0.05). It was suggested that there is no significant correlation between the protein expression of InsR in skeletal muscle and IR in GDM, but changes in TP of InsR are associated with IR in GDM.

Women who suffered from impaired carbohydrate metabolism during pregnancy are more likely to develop different types of diabetes later in their lives. The aim of this paper was to study the risk factors for the development of diabetes in group of women with gestational diabetes mellitus (GDM) in anamnesis. 200 women took part in this study, who had gestational diabetes diagnosed between 1980-1998. All women were divided into 4 groups depending on the type of disorders occurring at the moment of examination: DM1 - women diagnosed with type I diabetes, DM2 - women diagnosed with type 2 diabetes, IGT-women with glucose levels in OGTT, which applied to impaired glucose tolerance (acc. to WHO criteria), NDM - women with no clinical signs of diabetes, with normal result of OGTT. The risk of diabetes development is significantly higher (independently of the clinical type) in women who had had GDM include: high glucose levels at the time of GDM diagnosis, early onset of symptoms - related to weeks of gestation, and the insulin treatment during pregnancy. However multifactor analysis indicates that the only significant risk factors for DM 1 are early onset of diabetes during pregnancy and high glucose levels 2 hours after OGTT during pregnancy (p women who suffered from diabetes during pregnancy.

correlated to HOMA-IR, Visfatin and TNF-α. Conclusion: Vitamin D levels in patients with gestational diabetes mellitus decreased more significantly compared with that in healthy pregnant women. And the patients with vitamin D deficiency have higher risk to get GDM. Vitamin D can treat GDM by regulating the degree of insulin resistance and the level of adipokines. And it has clinical value in the treatment of GDM.

Metformin - a potentially effective drug for gestational diabetes mellitus: a systematic review and meta-analysis.

Metformin has been gradually used in the management of gestational diabetes mellitus (GDM). In order to prove the safety and efficacy of metformin used in pregnancy, we searched several databases for the reports of randomized trials comparing insulin and metformin used in GDM and conducted a meta-analysis. Data showed the rates of neonatal large for gestational age, cesarean section, neonatal respiratory distress and preterm birth were similar in both groups. Maternal glycated hemoglobin-% at gestational week 36-37 was significantly lower in metformin group, indicating good glycemic control of metformin. Maternal weight gain since enrollment to gestational week 36-37 was also lower in metformin group, making metformin worth using even when metformin is insufficient and supplementary insulin is needed. Data also showed that metformin significantly reduced the gestational hypertension complications in GDM patients, probably by reducing the endothelial activation and maternal inflammatory response of insulin resistance. Although metformin can cross the placenta, it is less likely to cause severe neonatal hypoglycemia compared with insulin since it neither stimulates pancreatic insulin release nor increases circulating insulin levels. According to most maternal and neonatal outcomes, metformin is an effective and safe alternative to insulin for GDM patients.

The Usage of Oral Anti Hyperglycemic Agent in Gestational Diabetes: Pros and Cons

Directory of Open Access Journals (Sweden)

Bram Pradipta

2014-06-01

Full Text Available The prevalence of gestational diabetes mellitus (GDM  is increasing as the pregnant population becomes older and more obese. Fifteen percent of GDM patients require medical intervention. Insulin is still the drug of choice because it has not been implicated as a teratogen in human pregnancies.Insulin has its disadvantages such as the need for injections, the risk of hypoglycaemia, excessive weight gain and the costs. The use of oral anti hyperglicemic agent (OAHA, traditionally contraindicated, now can be considered as an alternative for insulin which can be beneficial in developing countries. From four groups of OAHA, sulfonylurea and biguanides can be used during pregnancy. Studies and randomized controlled trial (RCT have been done and most summarized that it does not increase any maternal and perinatal morbidity. Most data also show that thereare also no differences in glycemic control or pregnancy outcomes compared with insulin. There are conflicting data shows metformin increase prevalence of preeclampsia patient and perinatal morbidity. OAHA usage, although not yet recommended internationally, can be considered in GDMpatients with uncontrolled blood sugar levels that require medical intervention but can not use insulin. Wellconducted, prospective, controlled studies regarding itsfeasibility in pregnant women with diabetes are still needed.Keywords:oral antihyperglycemic agent, gestational, diabetes

Objective: To explore the dynamic of high-sensitivity C-reactive protein (hs-CRP) and its correlation with insulin resistance (IR) during different stages of gestational diabetes mellitus (GDM). Methods: Thirty-two subjects with GDM and thirty-one cases of normal glucose tolerance (NGT) pregnant women were enrolled in the study, fasting insulin (FINS) were determined by radioimmunoassay, the fasting blood glucose (FBG) was measured by using glucose oxidase, immunoturbidimetry performed to evaluate serum hs-CRP levels. Tests repeated for each group according different stages of prenatal 25-28 weeks, 29- 32 weeks, 37-38 weeks and postpartum 6-8 weeks. IR was assessed by the homeostasis model assessment insulin resistance index (HOMA-IR). Results: (1)Serum hs-CRP levels in NGT and GDM had few change with gestational age, but both significantly decreased at postpartum. (2)Serum hs-CRP levels in GDM significantly increased than NGT in the same stage (t was 7.31, 7.78, 6.33, respectively, P<0.01 ). (3) HOMA-IR in GDM significantly increased than NGT in the same gestational stage (t was 31.18, 31.10, 28.39, respectively, P<0.01). (4)Pearson correlation analysis showed that FBG, FINS and hs-CRP had significant association with HOMA-IR (regression coefficient of 0.478, 0.902, 0.293, respectively, P<0.01). Multiple regression analysis identified FINS, FBG and hs-CRP as the factors significantly affecting HOMA-IR (regression coefficient of 0.441, 0.876, 0.261, respectively, P<0.01). Conclusion: Serum hs-CRP levels in GDM had few change with gestational age, but all significantly increased than NGT in the same stage, and which were the most significant factors affecting HOMA-IR.

Specific circulating metabolites have emerged as important risk factors for the development of diabetes. The acylcarnitines (acylCs) are a family of metabolites known to be elevated in type 2 diabetes (T2D) and linked to peripheral insulin resistance. However, the effect of acylCs on pancreatic β-cell function is not well understood. Here, we profiled circulating acylCs in two diabetes cohorts: 1 ) women with gestational diabetes mellitus (GDM) and 2 ) women with recent GDM who later developed impaired glucose tolerance (IGT), new-onset T2D, or returned to normoglycemia within a 2-year follow-up period. We observed a specific elevation in serum medium-chain (M)-acylCs, particularly hexanoyl- and octanoylcarnitine, among women with GDM and individuals with T2D without alteration in long-chain acylCs. Mice treated with M-acylCs exhibited glucose intolerance, attributed to impaired insulin secretion. Murine and human islets exposed to elevated levels of M-acylCs developed defects in glucose-stimulated insulin secretion and this was directly linked to reduced mitochondrial respiratory capacity and subsequent ability to couple glucose metabolism to insulin secretion. In conclusion, our study reveals that an elevation in circulating M-acylCs is associated with GDM and early stages of T2D onset and that this elevation directly impairs β-cell function. © 2018 by the American Diabetes Association.

Several studies have shown that women with pre-existing diabetes mellitus have significantly lower pregnancy-associated plasma protein-A levels than those without. This study aimed to evaluate whether first-trimester pregnancy-associated plasma protein-A multiple of median is associated with gestational diabetes mellitus in Chinese pregnant women. This prospectively collected case series was conducted in a regional hospital in Hong Kong. All consecutive Chinese women with a singleton pregnancy who attended the hospital for their first antenatal visit (before 14 weeks' gestation) from April to July 2014 were included. Pregnancy-associated plasma protein-A multiple of median was compared between the gestational diabetic (especially for early-onset gestational diabetes) and non-diabetic groups. The correlation between pregnancy-associated plasma protein-A level and glycosylated haemoglobin level in women with gestational diabetes was also examined. Of the 520 women recruited, gestational diabetes was diagnosed in 169 (32.5%). Among them, 43 (25.4%) had an early diagnosis, and 167 (98.8%) with the disease were managed by diet alone. The gestational diabetic group did not differ significantly to the non-diabetic group in pregnancy-associated plasma protein-A (0.97 vs 0.99, P=0.40) or free β-human chorionic gonadotrophin multiple of median (1.05 vs 1.02, P=0.29). Compared with the non-gestational diabetic group, women with early diagnosis of gestational diabetes had a non-significant reduction in pregnancy-associated plasma protein-A multiple of median (median, interquartile range: 0.86, 0.57-1.23 vs 0.99, 0.67-1.44; P=0.11). Pregnancy-associated plasma protein-A and glycosylated haemoglobin levels were not correlated in women with gestational diabetes (r=0.027; P=0.74). Chinese women with non-insulin-dependent gestational diabetes did not exhibit significant changes to pregnancy-associated plasma protein-A multiple of median nor a correlation between pregnancy

Full Text Available Background &Objective: Resistin is an important adipokin, secreted from adipocytes and causes insulin resistance. Gestational diabetes (GDM is characterized by insulin resistance in insulin target tissues. The goal of this research was to investigate whether there is a relationship among resistin and various clinical and metabolic parameters in GDM.Materials & Methods: 76 pregnant women who got the diagnosis of GDM were enrolled as the study group. 70 gestational age-matched pregnant women with normal glucose tolerance were recruited as the control group of the study. Serum resistin concentration, in addition to various metabolic and biochemical parameters, were measured in two groups.Results: Plasma resistin was not significantly different in GDM patients and subjects with normal glucose tolerance. Correlation analysis revealed that LDL cholesterol, total cholesterol and triglyceride were positively correlated with plasma resistin (P < 0.004, 0.01, and 0.02, respectively.Conclusion: Plasma resistin is correlated with insulin resistance, high serum LDL cholesterol, total cholesterol and TG in the Iranian GDM patients.

The VNTR polymorphism in the promoter region of the insulin gene (INS-VNTR) affects transcription rate and has been associated with insulin resistance and DM2. Gestational diabetes mellitus (GDM) is a multifactorial disorder, where both impaired insulin secretion and action may be involved. The aim of the study was to examine the distribution of the INS-VNTRs in women with GDM and to investigate possible associations with features of beta cell function and glycaemic control in this population. One hundred and sixty-one women with GDM and 111 normal pregnant women (n) were genotyped for INS-VNTR during the 24th-32nd pregnancy week. Glucose and insulin levels were determined during the diagnostic OGTT. The majority of the previous GDM women were also examined at 3-6 months post-partum. VNTR class III/III genotype was significantly more frequent in the GDM group 8.7% versus 2.7%, p=0.02 giving an OR of 3.97 (1.1-14.29). An increased frequency of the VNTR class III allele was found in those GDM women who required insulin for treatment compared to those controlled with diet alone (12.4% versus 4%, pwomen homozygous for the class III allele without reaching statistical significance (p=0.09). The INS-VNTR class III is more frequent in women who develop GDM, and may be associated with decreased ability of the beta cell to meet the increased insulin requirements as reflected by the need for insulin supplementation for adequate glycaemic control.

Adipocytes treated with neuraminidase show markedly reduced responsiveness to insulin without any alteration in insulin binding. In addition, several studies have separately demonstrated both insulin resistance and decreases in membrane sialic acid content and associated biosynthetic enzymes in diabetes mellitus. In the present study, the authors investigated the role that sialic acid residues may play in insulin action and in the hepatic insulin resistance associated with nonketotic diabetes. Primary cultures of hepatocytes from normal rats treated with neuraminidase demonstrated a dose-dependent decrease in insulin-stimulated lipogenesis. At a concentration of neuraminidase that decreases insulin action by 50%, 23% of total cellular sialic acid content was released. Neuraminidase-releasable sialic acid was significantly decreased in hepatocytes from diabetic rats and this was associated with significant insulin resistance. Treatment of hepatocytes from diabetic rats with cytidine 5'-monophospho-N-acetylneuraminic acid (CMP-NANA) enhanced insulin responsiveness 39%. The enhanced insulin responsiveness induced by CMP-NANA was blocked by cytidine 5'-monophosphate (CMP) suggesting that the CMP-NANA effect was catalyzed by a cell surface sialyl-transferase. CMP reduced neuraminidase-releasable [ 14 C]sialic acid incorporation into hepatocytes by 43%. The data demonstrate a role for cell surface sialic acid residues in hepatic insulin action and support a role for decreased cell surface sialic acid residues in the insulin resistance of diabetes mellitus

The relative roles(s) of impaired insulin secretion vs. insulin resistance in the development of gestational diabetes mellitus depend upon multiple risk factors and diagnostic criteria. Here, we explored their relative contribution to gestational diabetes as defined by the WHO 1999 (GDM1999) and adapted WHO 2013 (GDM2013) criteria, excluding the 1-h glucose value, in a high-risk Indian population from Punjab. Insulin secretion (HOMA2-B) and insulin action (HOMA2-IR) were assessed in 4665 Indian women with or without gestational diabetes defined by the GDM1999 or adapted GDM2013 criteria. Gestational diabetes defined using both criteria was associated with decreased insulin secretion compared with pregnant women with normal glucose tolerance. Women with gestational diabetes defined by the adapted GDM2013, but not GDM1999 criteria, were more insulin resistant than pregnant women with normal glucose tolerance, and furthermore displayed lower insulin secretion than GDM1999 women. Urban habitat, illiteracy, high age and low BMI were independently associated with reduced insulin secretion, whereas Sikh religion, increasing age and BMI, as well as a family history of diabetes were independently associated with increased insulin resistance. Gestational diabetes risk factors influence insulin secretion and action in North Indian women in a differential manner. Gestational diabetes classified using the adapted GDM2013 compared with GDM1999 criteria is associated with more severe impairments of insulin secretion and action. © 2017 Diabetes UK.

Full Text Available Abstract Background The aim was to evaluate the metabolic profile in conjunction with vascular function using the ambulatory arterial stiffness index (AASI in women with uncomplicated pregnancies and in women with gestational diabetes mellitus (GDM. Methods Plasma glucose, lipids, HOMA –IR (homeostasis model assessment of insulin resistance and AASI, as obtained from 24-hour ambulatory blood pressure monitoring in third trimester pregnancy and at three months postpartum, were measured in three groups of women: controls (N = 32, women with GDM on diet (N = 42 and women with GDM requiring insulin treatment (N = 10. Results Women with GDM had poorer glycemic control and higher HOMA-IR during and after pregnancy and their total and LDL (low density lipoprotein cholesterol levels were significantly higher after pregnancy than in the controls. After delivery, there was an improvement in AASI from 0.26 ± 0.10 to 0.17 ± 0.09 (P = 0.002 in women with GDM on diet, but not in women with GDM receiving insulin whose AASI tended to worsen after delivery from 0.30 ± 0.23 to 0.33 ± 0.09 (NS, then being significantly higher than in the other groups (P = 0.001-0.047. Conclusions Women with GDM had more unfavorable lipid profile and higher blood glucose values at three months after delivery, the metabolic profile being worst in women requiring insulin. Interestingly, the metabolic disturbances at three months postpartum were accompanied by a tendency towards arterial stiffness to increase in women requiring insulin.

CTX (crosslaps rather than osteopontin is associated with disturbed glucose metabolism in gestational diabetes.

Full Text Available OBJECTIVE: Reciprocal interaction between bone and glucose metabolism might play a pivotal role in the development of type 2 diabetes. We recently demonstrated that osteocalcin is increased in women with gestational diabetes (GDM compared to healthy pregnant women and related to enhanced insulin secretion. Here, we aimed to investigate the role of the bone resorption marker CTX and osteopontin (OPN, a key molecule in subclinical inflammation underlying insulin resistance, in gestational diabetes. METHODS: Insulin sensitivity and secretion (derived from OGTT as well as CTX and osteopontin were investigated in 26 GDM and 52 women with normal glucose tolerance during pregnancy [CON] between 24th and 28th gestational weeks; 24 women also underwent postpartum examination. RESULTS: CTX was significantly higher in GDM compared to CON (0.44±0.20 vs.0.28±0.12 ng/ml, p<.0001 and positively correlated with osteocalcin (R = 0.64, p<.0001 and parameters of insulin secretion. Osteopontin plasma concentrations were decreased in GDM compared to CON (28.81±22.12 vs.37.68±19.63 ng/ml, p = 0.04, and did not show any relation to insulin secretion or sensitivity, but were significantly correlated with CRP (R = 0.3, p<0.007 and liver enzymes. Twelve weeks after delivery CTX and OPN were increased compared to pregnancy (both p<.0001 and did not differ between GDM and CON. CONCLUSION: Our findings support the idea of a tight regulation between bone and glucose metabolism, and suggest, that less curbed CTX during pregnancy might be involved in osteocalcin-mediated amelioration of insulin secretion in GDM. On the other hand, osteopontin was unrelated to insulin resistance in GDM, but associated with inflammatory markers and liver enzymes in all women.

between hPGH and IGF-I in type 1 diabetes mellitus has not been investigated thoroughly. Furthermore, hPGH may be involved in the development of insulin resistance during pregnancy. In this prospective, longitudinal study, 51 type 1 diabetic subjects were followed with repeated blood sampling during......PGH was not correlated to the increase in insulin requirements, nor was any consistent relationship revealed during each gestational period. In conclusion, our study suggests a role for hPGH in the regulation of both IGFs and fetal growth in type 1 diabetes. In contrast, the increase in insulin requirements during...... pregnancy in type 1 diabetic subjects could not be related to hPGH levels....

This study compared plasma concentrations of amino acids in pregnant women with and without gestational diabetes mellitus (GDM) and identified the association between plasma amino acid levels and GDM, insulin resistance, and insulin secretion at 24-28 weeks of pregnancy. Circulating amino acid levels were evaluated using high-performance liquid chromatography at 24-28 weeks of pregnancy in 25 non-GDM and 64 GDM women after adjusting for covariates such as maternal age, body mass index (BMI) before pregnancy, BMI and gestational age at screening GDM, and daily caloric intake. Backward stepwise logistic regression analysis was used to identify the predictors of developing GDM, and homeostatic model assessments for insulin resistance (HOMA-IR) and β-cell function (HOMA-B). Circulating levels of amino acids except threonine and tyrosine were significantly higher in GDM women than non-GDM women. Along with the intakes of energy, protein, and fat from animal sources, the intakes of each amino acid were significantly higher in the GDM group without a direct correlation to plasma amino acid levels. The variation in GDM development was explained by maternal age, diastolic blood pressure, and plasma lysine levels (R(2)=0.691). Height, BMI before pregnancy, systolic blood pressure, and plasma tyrosine and valine levels accounted for the variation in HOMA-IR (R(2)=0.589). The 53.3% variation of HOMA-B was explained by maternal age, BMI at GDM screening, plasma insulin level at 1 h during the oral glucose tolerance test (OGTT), and plasma valine level. Circulating concentrations of lysine, tyrosine, and valine were independently and positively associated with GDM through modifying insulin resistance and secretion.

Polycystic ovary syndrome (PCOS) and gestational diabetes mellitus (GDM) are both characterized by an increase in insulin resistance. Our goal in the present study was to measure insulin resistance (as estimated by homeostasis model assessment, sex hormone-binding globulin (SHBG) and adiponectin concentrations) and parameters of low-grade inflammation in non-diabetic, non-hyperandrogenic ovulatory women with previous GDM (pGDM) and in non-diabetic women with classic PCOS, characterized by hyperandrogenism and oligo/anovulation. We evaluated 20 women with PCOS, 18 women with pGDM and 19 controls, all matched according to body mass index (BMI). Fasting blood samples were drawn in all women 3-6 days after spontaneous or dydrogesterone-induced withdrawal bleeding. Body fat distribution was assessed using dual-energy X-ray absorptiometry in all women. After adjusting for age and percent body fat, measures of insulin resistance such as SHBG and adiponectin concentrations were decreased and central obesity was increased in women with PCOS and pGDM compared with controls (all p PCOS compared with BMI-matched controls (all p insulin resistance are increased in both women with PCOS and women with pGDM, while low-grade inflammation is increased only in PCOS. PCOS and GDM might represent specific phenotypes of one disease entity with an increased risk of cardiovascular disease, whereby women with PCOS demonstrate an augmented cardiovascular risk profile.

Type II diabetes originates from various genetic and environmental factors. Recent studies showed that an adverse uterine environment such as that caused by a gestational low-protein (LP) diet can cause insulin resistance in adult offspring. The mechanism of insulin resistance induced by gestational protein restriction is not clearly understood. Our aim was to investigate the role of insulin signaling molecules in gastrocnemius muscles of gestational LP diet–exposed male offspring to understand their role in LP-induced insulin resistance. Pregnant Wistar rats were fed a control (20% protein) or isocaloric LP (6%) diet from gestational day 4 until delivery and a normal diet after weaning. Only male offspring were used in this study. Glucose and insulin responses were assessed after a glucose tolerance test. mRNA and protein levels of molecules involved in insulin signaling were assessed at 4 months in gastrocnemius muscles. Muscles were incubated ex vivo with insulin to evaluate insulin-induced phosphorylation of insulin receptor (IR), Insulin receptor substrate-1, Akt, and AS160. LP diet-fed rats gained less weight than controls during pregnancy. Male pups from LP diet–fed mothers were smaller but exhibited catch-up growth. Plasma glucose and insulin levels were elevated in LP offspring when subjected to a glucose tolerance test; however, fasting levels were comparable. LP offspring showed increased expression of IR and AS160 in gastrocnemius muscles. Ex vivo treatment of muscles with insulin showed increased phosphorylation of IR (Tyr972) in controls, but LP rats showed higher basal phosphorylation. Phosphorylation of Insulin receptor substrate-1 (Tyr608, Tyr895, Ser307, and Ser318) and AS160 (Thr642) were defective in LP offspring. Further, glucose transporter type 4 translocation in LP offspring was also impaired. A gestational LP diet leads to insulin resistance in adult offspring by a mechanism involving inefficient insulin-induced IR, Insulin receptor

To identify factors predicting early postpartum glucose intolerance in Japanese women with gestational diabetes mellitus, using decision-curve analysis. A retrospective cohort study was performed. The participants were 123 Japanese women with gestational diabetes who underwent 75-g oral glucose tolerance tests at 8-12 weeks after delivery. They were divided into a glucose intolerance and a normal glucose tolerance group based on postpartum oral glucose tolerance test results. Analysis of the pregnancy oral glucose tolerance test results showed predictive factors for postpartum glucose intolerance. We also evaluated the clinical usefulness of the prediction model based on decision-curve analysis. Of 123 women, 78 (63.4%) had normoglycaemia and 45 (36.6%) had glucose intolerance. Multivariable logistic regression analysis showed insulinogenic index/fasting immunoreactive insulin and summation of glucose levels, assessed during pregnancy oral glucose tolerance tests (total glucose), to be independent risk factors for postpartum glucose intolerance. Evaluating the regression models, the best discrimination (area under the curve 0.725) was obtained using the basic model (i.e. age, family history of diabetes, BMI ≥25 kg/m 2 and use of insulin during pregnancy) plus insulinogenic index/fasting immunoreactive insulin intolerance. Insulinogenic index/fasting immunoreactive insulin calculated using oral glucose tolerance test results during pregnancy is potentially useful for predicting early postpartum glucose intolerance in Japanese women with gestational diabetes.

To evaluate changes of pancreatic size with aging in control subjects and in non-insulin- dependent diabetic patients. Two groups of non-insulin-dependent diabetic patients were examined; one had been treated with an oral hypoglycemic agent(n=59), and the other with insulin(n=56). The CT findings of 175 patients without clinical evidence of pancreatic disease were included as a normal control. In control subjects, pancreatic size and age correlated. The pancreas was smaller in non-insulin-dependent diabetics than in control subjects and smaller in insulin- treated non-insulin-dependent diabetics than in non-insulin treated patients. The pancreas was smaller in non-insulin-dependent diabetic patients than in control subjects within the same age range

To determine efficacy of metformin in maintaining euglycemia in patients with GDM among women presenting in our institution. Methodology: It was a prospective study conducted at the department of Obstetrics and Gynecology Railway teaching Hospital IIMCT, Rawalpindi from October 2014 to April 2015 and included 60 patients of 18-45 years of age at 10-32 weeks gestation in singleton pregnancy with fasting blood glucose levels > 6.1 mmol /L and 2 hours Post Prandial levels > 7.8 mml/L Metformin is started at a dose of 500 mg daily and increased up to 2500 mg daily. Aim was to keep fasting sugar level between 3.5 - 5.9 mmol/L and 2 hours post prandial < 7.8 mmol/L. Results: The median daily dose of metformin was 1500 mg. The mean gestational age at delivery was 38.1 weeks. Neonatal hypoglycemia (glucose level < 1.6mmol/L ) was less common. The only adverse effects of metformin was GI upset (13.1 %) The results of postpartum questionnaire assessing acceptability of treatment among women treated with metformin alone, 65.6 % said they would chose metformin in subsequent pregnancy. The efficacy of metformin alone was 85.7%. Conclusion: In women with gestational diabetes mellitus, metformin (alone or with supplemental insulin) is not associated with increased prenatal complications. The women preferred metformin to insulin treatment. (author)

Gestational Diabetes Mellitus: Risks and Management during and after Pregnancy

Buchanan, Thomas A.; Xiang, Anny H.; Page, Kathleen A.

2015-01-01

Gestational diabetes mellitus (GDM) represents glucose levels in the high end of the population distribution during pregnancy. GDM carries a small but potentially important risk of adverse perinatal outcomes and a longer-term risk of obesity and glucose intolerance in offspring. Mothers with GDM have an excess of hypertensive disorders during pregnancy and a high risk of diabetes mellitus thereafter. Diagnosing and treating GDM can reduce perinatal complications, but only a small fraction of pregnancies benefit. Nutritional management is the cornerstone of treatment; insulin, glyburide and metformin can be used to intensify treatment. Fetal measurements compliment maternal glucose measurements in identifying pregnancies that need such intensification. Glucose testing shortly after pregnancy can stratify the near-term diabetes risk in mothers, Thereafter, annual glucose and HbA1C testing can detect deteriorating glycaemic control, a harbinger of future diabetes, usually type 2. Interventions that mitigate obesity or its metabolic effects are most potent in preventing or delaying diabetes. Lifestyle modification is the primary approach; use of medications for diabetes prevention after GDM remains controversial. Family planning allows optimization of health in subsequent pregnancies. Breastfeeding may reduce obesity in children and is recommended. Families should be encouraged to help children adopt lifestyles that reduce the risk of obesity. PMID:22751341

To verify the usefulness of the World Health Organization criteria for the diagnosis of gestational diabetes mellitus in pregnant women and its effectiveness in the prevention of maternal and neonatal adverse results in women younger than 35 years without apparent risk factors for gestational diabetes mellitus. This is a retrospective study based on population involving 1360 pregnant women who delivered and who were followed-up in a university hospital in Istanbul. All women underwent the 75-g oral glucose tolerance test screening, usually in between the 24(th)-28(th) weeks of pregnancy. In all cases, the identification of gestational diabetes mellitus was determined in accordance with the World Health Organization criteria. Approximately 28% of the pregnant women aged younger than 35 years with no risk factors for gestational diabetes mellitus were diagnosed with the oral glucose tolerance test in this study. In the gestational diabetes mellitus group, the primary cesarean section rate was importantly higher than that in the non-gestational diabetes mellitus group. Preterm delivery was also associated with gestational diabetes mellitus. The diagnosis of gestational diabetes mellitus was strongly associated with admittance to the neonatal intensive care unit. Neonatal respiratory problems didn't showed any significant deviation between the groups. There was a moderate association between gestational diabetes mellitus and metabolic complications. Pregnant women with no obvious risk factors were diagnosed with gestational diabetes mellitus using the World Health Organization criteria. The treatment of these women potentially reduced their risk of adverse maternal and neonatal hyperglycemia-related events, such as cesarean section, polyhydramnios, preterm delivery, admission to neonatal intensive care unit, large for gestational age, and higher neonatal weight.

The role of sleep duration and sleep disordered breathing in gestational diabetes mellitus

2018-01-01

Full Text Available Many women experience sleep problems during pregnancy. This includes difficulty initiating and maintaining sleep due to physiologic changes that occur as pregnancy progresses, as well as increased symptoms of sleep-disordered breathing (SDB. Growing evidence indicates that sleep deficiency alters glucose metabolism and increases risk of diabetes. Poor sleep may exacerbate the progressive increase in insulin resistance that normally occurs during pregnancy, thus contributing to the development of maternal hyperglycemia. Here, we critically review evidence that exposure to short sleep duration or SDB during pregnancy is associated with gestational diabetes mellitus (GDM. Several studies have found that the frequency of GDM is higher in women exposed to short sleep compared with longer sleep durations. Despite mixed evidence regarding whether symptoms of SDB (e.g., frequent snoring are associated with GDM after adjusting for BMI or obesity, it has been shown that clinically-diagnosed SDB is prospectively associated with GDM. There are multiple mechanisms that may link sleep deprivation and SDB with insulin resistance, including increased levels of oxidative stress, inflammation, sympathetic activity, and cortisol. Despite emerging evidence that sleep deficiency and SDB are associated with increased risk of GDM, it has yet to be demonstrated that improving sleep in pregnant women (e.g., by extending sleep duration or treating SDB protects against the development of hyperglycemia. If a causal relationship can be established, behavioral therapies for improving sleep can potentially be used to reduce the risk and burden of GDM.

This work reports the experience with use of continuous subcutaneous insulin infusion (CSII) in 112 type 1 diabetic patients followed up for 7 years and previously treated with multiple daily insulin injections (MDII). A retrospective, observational study in 112 patients with diabetes mellitus treated with CSII from 2005 to 2012, previously treated with MDII and receiving individualized diabetic education with a specific protocol. Variables analyzed included: prevalence of the different indications of pump treatment; mean annual HbA1c and fructosamine values before and after CSII treatment; and hypoglycemia frequency and symptoms. The most common reason for pump treatment was brittle diabetes (74.1%), followed by frequent or severe hypoglycemia or hypoglycemia unawareness (44.6%). Other indications were irregular food intake times for professional reasons (20.2%), dawn phenomenon (15.7%), pregnancy (12.3%), requirement of very low insulin doses (8.9%), and gestational diabetes (0.9%). HbA1c decreased by between 0.6% and 0.9%, and fructosamine by between 5.1% and 12.26%. Nine percent of patients experienced hypoglycemia weekly, 24% every two weeks, and 48% monthly. No hypoglycemia occurred in 19% of patients. Only 10% had neuroglycopenic symptoms. Hypoglycemia unawareness was found in 21%. Hypoglycemia was more common at treatment start, and its frequency rapidly decreased thereafter. CSII therapy provides a better glycemic control than MDII treatment. Specific patient training and fine adjustment of insulin infusion doses are required to prevent hypoglycemic episodes, which are the most common complications, mainly at the start of treatment.

Full Text Available The GLUT4 transporter plays a key role in insulin-induced glucose uptake, which is impaired in insulin resistance. The objective of the present study was to investigate the tissue content and the subcellular distribution of GLUT4 protein in 4- to 12-year-old control, obese and insulin-treated diabetic mongrel female dogs (4 animals per group. The parametrial white adipose tissue was sampled and processed to obtain both plasma membrane and microsome subcellular fractions for GLUT4 analysis by Western blotting. There was no significant difference in glycemia and insulinemia between control and obese animals. Diabetic dogs showed hyperglycemia (369.9 ± 89.9 mg/dl. Compared to control, the plasma membrane GLUT4, reported per g tissue, was reduced by 55% (P < 0.01 in obese dogs, and increased by 30% (P < 0.05 in diabetic dogs, and the microsomal GLUT4 was increased by ~45% (P < 0.001 in both obese and diabetic animals. Considering the sum of GLUT4 measured in plasma membrane and microsome as total cellular GLUT4, percent GLUT4 present in plasma membrane was reduced by ~65% (P < 0.001 in obese compared to control and diabetic animals. Since insulin stimulates GLUT4 translocation to the plasma membrane, percent GLUT4 in plasma membrane was divided by the insulinemia at the time of tissue removal and was found to be reduced by 75% (P < 0.01 in obese compared to control dogs. We conclude that the insulin-stimulated translocation of GLUT4 to the cell surface is reduced in obese female dogs. This probably contributes to insulin resistance, which plays an important role in glucose homeostasis in dogs.

To evaluate the associations between adiponectin levels and 1) the risk of developing gestational diabetes mellitus (GDM), and 2) insulin resistance/sensitivity, β-cell function, and compensation indices in a prospective cohort representative of the general population of pregnant women. We performed anthropometric measurements and collected blood samples at 1st (6-13 weeks) and 2nd (24-28 weeks) trimesters. Diagnosis of GDM was made at 2nd trimester based on a 75-g oral glucose tolerance test (International Association of the Diabetes and Pregnancy Study Groups criteria). Insulin was measured (ELISA; Luminex) to estimate homeostasis model assessment of insulin resistance (HOMA-IR), β-cell function (HOMA-B), insulin sensitivity (Matsuda index), insulin secretion (AUC(insulin/glucose)), and β-cell compensation (insulin secretion sensitivity index-2). Adiponectin was measured by radioimmunoassay. Among the 445 participants included in this study, 38 women developed GDM. Women who developed GDM had lower 1st-trimester adiponectin levels (9.67 ± 3.84 vs. 11.92 ± 4.59 µg/mL in women with normal glucose tolerance). Lower adiponectin levels were associated with higher risk of developing GDM (OR, 1.12 per 1 µg/mL decrease of adiponectin levels; P = 0.02, adjusted for BMI and HbA1c at 1st trimester). Adiponectin levels at 1st and 2nd trimesters were associated with HOMA-IR (both: r = -0.22, P insulin/glucose). Pregnant women with lower adiponectin levels at 1st trimester have higher levels of insulin resistance and are more likely to develop GDM independently of adiposity or glycemic measurements.

Full Text Available Background &Objective: Adiponectin is an adipose tissue adipokin that may contribute to obesity and insulin resistantance. The aim of this study was to evaluate the associations between serum concentrations of adiponectin and insulin resistance in gestational diabetes (GDM.Materials & Methods: Serum adiponectin levels, fasting blood sugar (FBS, glycated hemoglobin (HbA1C, insulin levels and blood lipids were measured in 66 women with GDM and 70 pregnant women without GDM. The associations between serum concentrations of adiponectin and insulin resistance were evaluated using the homeostasis model assessment of insulin resistance (HOMA–IR and quantitative insulin sensitivity check index (QUICKI.Results: There were statistically significant between-group differences in FBS, HbA1C and HOMA–IR. Adiponectin concentrations were not significantly different in GDM women in comparison with the control group. However, GDM women above the age of 30 have significantly lower adiponectin concentrations than those without GDM. Adiponectin was positively associated with QUICKI (r = 0.268, P < 0.03 and inversely related to HOMA–IR (r = 0.238, P < 0.05.Conclusion: Adiponectin is significantly decreased in older women with GDM. Deficiency of adiponectin may correlate with insulin resistance in GDM.

The aim of the present study is to assess the impact of adding oral metformin to insulin therapy in pregnant women with insulin-resistant diabetes mellitus. The current non-inferiority randomized controlled trial was conducted at Ain Shams University Maternity Hospital. The study included pregnant women with gestational or pre-existing diabetes mellitus at gestations between 20 and 34 weeks, who showed insulin resistance (defined as poor glycemic control at a daily dose of ≥1.12 units/kg). Recruited women were randomized into one of two groups: group I, including women who received oral metformin without increasing the insulin dose; and group II, including women who had their insulin dose increased. The primary outcome was maternal glycemic control. Secondary outcomes included maternal bouts of hypoglycemia, need for another hospital admission for uncontrolled diabetes during pregnancy, gestational age at delivery, mode of delivery, birth weight, birth trauma, congenital anomalies, 1- and 5-min Apgar score, neonatal hypoglycemia, need for neonatal intensive care unit (NICU) admission and adverse neonatal outcomes. A total number of 154 women with diabetes mellitus with pregnancy were approached; of them 90 women were eligible and were randomly allocated and included in the final analysis. The recruited 90 women were randomized into one of two groups: group I (metformin group) (n = 46), including women who received oral metformin in addition to the same initial insulin dose; and group II (control group) (n = 44), including women who had their insulin dose increased according to the standard protocol. The mean age of included women was 29.84 ± 5.37 years (range 20-42 years). The mean gestational age at recruitment was 28.7 ± 3.71 weeks (range 21-34 weeks). Among the 46 women of group I, 17 (36.9 %) women reached proper glycemic control at a daily metformin dose of 1,500 mg, 18 (39.2 %) at a daily dose of 2,000 mg, while 11 (23.9 %) received metformin at a daily

Studies in rodents suggest that metformin treatment during pregnancy may have harmful effects on testicular development in offspring. Our aim was to determine whether metformin treatment of gestational diabetes mellitus (GDM) affects testicular size in male offspring. We compared the testicular size in prepubertal boys born to mothers who participated in a randomized controlled trial (RCT) comparing metformin with insulin in the treatment of GDM. Twenty-five (42.4% of invited) and 27 (52.9% of invited) boys whose mothers had been treated with metformin or insulin, respectively, participated in the study. Testicular size was measured by a ruler, an orchidometer, and by ultrasonography at the age of 33 to 85 months. The mean age of the boys was 60 months at the time of examination, and did not differ between the metformin and insulin group (p = 0.88). There was no difference in testicular size between the boys in the two groups (p always ≥ 0.40), and there were no significant differences in height, weight, BMI, BMI z-score, or waist-to-hip ratio (WHR) between the boys in the groups. Prepubertal testicular size did not differ between offspring born to metformin-treated mothers and those born to insulin-treated mothers.

Full Text Available The article reviews the available data on investigations in the field of electrolyte (calcium, magnesium, hormonal (insulin, leptin and hemostasis disturbances in term newborns from women with gestational diabetes; possible mechanisms of their development are also highlighted. The review describes changes in blood glucose concentration in term newborns from women with gestational diabetes, and their impact on the child's condition. In addition to already known factors causing macrosomia and other metabolic disorders in term neonates, the role of leptin (peptide hormone that regulates energy metabolism is quite discussable. Low leptin levels lead to the development of obesity. It is also confirmed, that leptin influences brain development of the newborn, leading to later cognitive deficits in children from women with GDM. The aim of the review is to summarize the available data on investigations in the field of electrolyte (calcium, magnesium, hormonal (insulin, leptin and hemostasis disturbances in term newborns from women with gestational diabetes.

A review of current treatment strategies for gestational diabetes mellitus

Kristi W Kelley

2015-07-01

Full Text Available Approximately 90% of diabetes cases in pregnant women are considered gestational diabetes mellitus (GDM. It is well known that uncontrolled glucose results in poor pregnancy outcomes in both the mother and fetus. Worldwide there are many guidelines with recommendations for appropriate management strategies for GDM once lifestyle modifications have been instituted and failed to achieve control. The efficacy and particularly the safety of other treatment modalities for GDM has been the source of much debate in recent years. Studies that have demonstrated the safety and efficacy of both glyburide and metformin in the management of patients with GDM will be reviewed. There is a lack of evidence with other oral and injectable non-insulin agents to control blood glucose in GDM. The role of insulin will be discussed, with emphasis on insulin analogs. Ideal patient characteristics for each treatment modality will be reviewed. In addition, recommendations for postpartum screening of patients will be described as well as recommendations for use of agents to manage subsequent type 2 diabetes in patients who are breastfeeding.

Full Text Available Abstract Background Diabetes is known to be associated with cancer of the pancreas, though there is some debate as to whether it is a cause or a consequence of the disease. We investigated the incidence of pancreatic cancer in a cohort of 37926 Israeli women followed for 28–40 years for whom information on diabetes had been collected at the time they gave birth, in 1964–1976, in Jerusalem. There were 54 cases of pancreatic cancer ascertained from the Israel Cancer Registry during follow-up. Methods We used Cox proportional hazards models to adjust for age at baseline and explore effects of other risk factors, including ethnic groups, preeclampsia, birth order and birth weight of offspring. Results We observed no cases of pancreatic cancer in the women with insulin dependent diabetes; however, there were five cases in the women with gestational diabetes. The interval between the record of diabetes in pregnancy and the diagnosis of pancreatic cancer ranged from 14–35 years. Women with a history of gestational diabetes showed a relative risk of pancreatic cancer of 7.1 (95% confidence interval, 2.8–18.0. Conclusion We conclude that gestational diabetes is strongly related to the risk of cancer of the pancreas in women in this population, and that gestational diabetes can precede cancer diagnosis by many years.

The pathophysiology of gestational diabetes itself causes hyperstimulation of adipose tissue and of the placenta cells increasing the production of inflammatory cytokines, which cause changes in the tissues exposed such as the placenta and foetus. Therefore, the objective of this study was to compare metabolic markers and endothelial dysfunction in umbilical cord blood, as well as to determine the presence of atherosclerosis in the placentas of newborn infants of patients with gestational diabetes and in patients with normally progressing pregnancies. An analytical cross-sectional study was carried out in 84 patients, obtaining data such as age, smoking and weight gain in pregnancy; the gestational age of the newborns was determined by Capurro, and their weight and destination subsequent to birth, the placentas were also collected in order to look for atherosclerosis through histological studies and glucose, insulin, VLDL-C, HDL-C, triglycerides, cholesterol, fibrinogen, PCR and markers of endothelial dysfunction (adiponectin, VCAM-1, ICAM-1 and IL-6) were determined in blood samples obtained from the umbilical cord. Placental atherosclerosis presented in 28.94% of the group with gestational diabetes compared to 10.52% of the group with normally progressing pregnancies (P=.044); differences were found in glucose, cholesterol, triglycerides, fibrinogen, HOMA-IR, PCR-us, HDL-C, not in VLDL-C. Twenty-one point five percent of the newborns of the gestational diabetes patients required hospitalization, against 5.2% in the control group, Pregnancies that involve diabetes have higher proportion of atherosclerosis, hospitalization of the newborn, insulin resistance, as well as elevation of markers associated with inflammation and endothelial dysfunction in umbilical cord blood.

Controversies in gestational diabetes.

Nolan, Christopher J

Gestational diabetes mellitus (GDM) and controversy are old friends. However, several major studies in the field have clarified some of the main issues. There is now no doubt that hyperglycaemia, at levels less than those that occur in overt diabetes, is associated with adverse pregnancy outcomes, such as large-for-gestational age infants, neonatal hyperinsulinism, neonatal hypoglycaemia and pre-eclampsia. We also have evidence now that a standard approach to GDM with diagnosis at 24-28 weeks, dietary advice, self-monitoring of blood glucose and insulin therapy as needed reduces these adverse perinatal outcomes. Unknown, however, is if this same approach is effective at reducing long-term risks of metabolic syndrome, type 2 diabetes and cardiovascular disease in both the mothers and babies. For example, could our management strategies miss critical time points of fuel-mediated injury to the foetus important for the baby's long-term metabolic health? The implications of a recent international consensus statement on new diagnostic criteria for GDM are discussed, as well as issues relating to the timing of diagnosis. The potential place for a risk calculator for adverse outcomes in GDM pregnancy that takes into account glycaemic and non-glycaemic risk factors is considered. Such a tool could help stratify GDM women to different levels of care. Ongoing issues relating to maternal glycaemic and foetal growth targets, and the use of oral hypoglycaemic agents in GDM are discussed. To resolve some of the remaining controversies, further carefully designed randomised controlled trials in GDM with long-term follow-up of both mothers and babies are necessary.

The aim of this study in patients with gestational diabetes mellitus (GDM) was to evaluate the relationship of insulin resistance and secretion to area-under-the-sensor glucose concentration-time curve from before to 120 min postmeal (CGM-AUC(0-120 min)) as determined with continuous glucose monitoring (CGM). Immunoreactive insulin and HbA1c were determined in 22 Japanese patients with GDM undergoing a 75 g oral glucose tolerance test. Patients underwent CGM within 3 weeks of receiving a diagnosis of GDM. HbA1c (NGSP) was 5.5 ± 0.4%, BMI was 24.8 ± 5.3 kg/m(2), mean sensor glucose by CGM was 94.2 ± 10.3 mg/dL, standard deviation was 17.5 ± 4.4 mg/dL, and CGM-AUC(0-120 min) was 204.2 ± 23.8 h mg/dL. The insulin resistance indices the homeostasis model assessment ratio (HOMA-R), quantitative insulin sensitivity check index (QUICKI), and the Matsuda Index were correlated with CGM-AUC(0-120 min). The disposition index (DI), which was used to evaluate insulin secretion, was negatively correlated with CGM-AUC(0-120 min). Not only insulin resistance but also beta cell dysfunction contributes to postprandial hyperglycemia in Japanese patients with GDM.

Women with gestational diabetes are at high risk of developing type 2 diabetes, which could be prevented or delayed by lifestyle modification. Lifestyle interventions need to take into account the specific situation of women with gestational diabetes. We aimed to gain a deeper understanding of women's experiences of gestational diabetes, their diabetes risk perceptions, and their views on type 2 diabetes prevention, to inform future lifestyle interventions. We conducted a metasynthesis that included 16 qualitative studies and identified 11 themes. Factors that require consideration when developing a type 2 diabetes prevention intervention in this population include addressing the emotional impact of gestational diabetes; providing women with clear and timely information about future diabetes risk; and offering an intervention that fits with women's multiple roles as caregivers, workers, and patients, and focuses on the health of the whole family.

Rats were made hypothyroid by treating with a single dose of 800 μCi of 131 I and hyperthyroid condition was created by administering 90 μg of thyroxine daily for 2 weeks. Diabetes was produced by administering single dose of alloxan monohydrate. Hypothyroid rats showed significant increase in 125 I-insulin binding with its liver plasma membrane receptors with respect to normal rats. In the case of hypothyroid diabetic rats such binding was greater as compared to hypothyroid rats without diabetes. Hyperthyroid rats with respect to normal control rats showed a decrease in 125 I-insulin binding to its liver plasma membrane receptors. When hyperthyroid rats were made diabetic, 125 I-insulin binding to its receptors was further decreased. The study infers that hyper-thyrodism further decreases insulin binding to its receptors which has already been decreased in diabetes. Hypothyroidism, on the other hand, improves upon the decreased insulin binding to its receptors in diabetes. (author). 16 refs., 6 figs., 2 tabs

Full Text Available Aim. Determine the metabolic profile and identify risk factors of women transitioning from gestational diabetes mellitus (GDM to type 2 diabetes mellitus (T2DM. Methods. 237 women diagnosed with GDM underwent an oral glucose tolerance test (OGTT, anthropometrics assessment, and completed lifestyle questionnaires six years after pregnancy. Blood was analysed for clinical variables (e.g., insulin, glucose, HbA1c, adiponectin, leptin, and lipid levels and NMR metabolomics. Based on the OGTT, women were divided into three groups: normal glucose tolerance (NGT, impaired glucose tolerance (IGT, and T2DM. Results. Six years after GDM, 19% of subjects had T2DM and 19% IGT. After BMI adjustment, the IGT group had lower HDL, higher leptin, and higher free fatty acid (FFA levels, and the T2DM group higher triglyceride, FFA, and C-reactive protein levels than the NGT group. IGT and T2DM groups reported lower physical activity. NMR measurements revealed that levels of branched-chain amino acids (BCAAs and the valine metabolite 3-hydroxyisobyturate were higher in T2DM and IGT groups and correlated with measures of insulin resistance and lipid metabolism. Conclusion. In addition to well-known clinical risk factors, BCAAs and 3-hydroxyisobyturate are potential markers to be evaluated as predictors of metabolic risk after pregnancy complicated by GDM.

Gestational diabetes mellitus (GDM), defined as any degree of glucose intolerance with onset or first recognition during pregnancy, is characterized by underlying maternal defects in the β-cell response to insulin during pregnancy. Women with a previous history of GDM have a greater than 7-fold higher risk of developing postpartum diabetes compared with women without GDM. Various risk factors for postpartum diabetes have been identified, including maternal age, glucose levels in pregnancy, family history of diabetes, pre-pregnancy and postpartum body mass index, dietary patterns, physical activity, and breastfeeding. Genetic studies revealed that GDM shares common genetic variants with type 2 diabetes. A number of lifestyle interventional trials that aimed to ameliorate modifiable risk factors, including diet, exercise, and breastfeeding, succeeded in reducing the incidence of postpartum diabetes, weight retention, and other obesity-related morbidities. The present review summarizes the findings of previous studies on the incidence and risk factors of postpartum diabetes and discusses recent lifestyle interventional trials that attempted to prevent postpartum diabetes.

Eekhoff Elisabeth MW

2009-01-01

Full Text Available Abstract Background Pregnancy is a period in the life of women that is often associated with decreased daily physical activity and/or exercise. However, maintaining adequate levels of daily physical activity during pregnancy is important for mother and child. Studies suggest that moderate daily physical activity and exercise during pregnancy are associated with reductions in the risk of gestational diabetes mellitus (GDM. However, at present, physical activity is not routinely advised to pregnant women at risk for gestational diabetes in the Netherlands. In FitFor2-study we aim to assess whether an exercise program can improve insulin sensitivity and fasting plasma glucose levels of women at high risk for gestational diabetes, assuming that this will lower their risk of gestational diabetes. Methods The FitFor2-study is a randomised controlled trial. Women who visit one of the participating hospitals or midwifery practices and who are at risk for gestational diabetes are eligible to participate. After baseline measurement they are randomly allocated to in the intervention or control group. The intervention group receives an exercise program twice a week in addition to usual care. The exercise program consist of aerobic and strength exercises and takes place under close supervision of a physiotherapist. Data are collected at 15, 24 and 32 weeks of pregnancy and 12 weeks after delivery. Primary maternal outcome measures are fasting plasma glucose and relative increase in insulin resistance. Primary neonatal outcome is birth weight. Secondary outcome measures are: maternal serum triglycerides, HDL, cholesterol, HbA1c, maternal weight gain during pregnancy, maternal physical activity level, foetal growth. Discussion If the FitFor2 intervention program proves to be effective, obstetricians and midwives should refer women at risk for GDM to a special exercise program. Exercise programs for pregnant women under supervision of an experienced trainer are

Perceived psychosocial stress and gestational weight gain among women with gestational diabetes.

Full Text Available Growing evidence links perceived stress-a potentially modifiable psychosocial risk factor-with health behaviors and obesity. Yet little is known about the relationship between stress during pregnancy and gestational weight gain, particularly among women with pregnancy complications. We conducted a cross-sectional analysis to examine associations between psychosocial stress during pregnancy and gestational weight gain among women with gestational diabetes. We used baseline data from the Gestational Diabetes's Effects on Moms (GEM study: 1,353 women with gestational diabetes who delivered a term singleton within Kaiser Permanente Northern California were included. Perceived stress near the time of gestational diabetes diagnosis was measured using the validated Perceived Stress Scale (PSS10. Gestational weight gain was categorized according to the 2009 Institute of Medicine recommendations. Binomial regression analyses adjusted for gestational age and maternal age at the time of gestational diabetes diagnosis, and race/ethnicity and estimated rate ratios (RR and their 95% confidence interval (CI. Among women with a normal pregravid Body Mass Index (BMI 18.5-24.9 kg/m2, there was a significant association between high (Q4 PSS score and risk of both exceeding and gaining below the Institute of Medicine recommendations compared to those with lower stress (Q1 [adjusted RR = 2.16 95% CI 1.45-3.21; RR = 1.39 95% CI 1.01-1.91, respectively.] Among women with pregravid overweight/obesity (BMI≥25 kg/m2, there was no association. Although the temporal relationship could not be established from this study, there may be a complex interplay between psychosocial stress and gestational weight gain among women with gestational diabetes. Further studies examining stress earlier in pregnancy, risk of developing gestational diabetes and excess/inadequate gestational weight gain are warranted to clarify these complex relationships.

2016-09-07

Gestational diabetes mellitus (GDM) is any degree of glucose intolerance that first presents and is recognised during pregnancy and usually resolves after the birth of the baby. GDM is associated with increased short- and long-term morbidity for the mother and her baby. Treatment usually includes lifestyle modification and/or pharmacological therapy (oral antidiabetic agents or insulin) with the aim to maintain treatment targets for blood glucose concentrations. Finding novel treatment agents which are effective, acceptable and safe for the mother and her baby are important. One such emerging potential intervention is myo-inositol which is an isomer of inositol and occurs endogenously and is found in natural dietary sources such as fruits, vegetables, nuts and cereals. To assess if dietary supplementation with myo-inositol during pregnancy is safe and effective, for the mother and fetus, in treating gestational diabetes. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 April 2016), ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (7 April 2016), and reference lists of retrieved studies. All published and unpublished randomised controlled trials or cluster-randomised controlled trials reporting on the use of myo-inositol compared with placebo, no treatment or another intervention for the treatment of women with gestational diabetes. Quasi-randomised and cross-over studies are not eligible for inclusion. Women with pre-existing diabetes were excluded. Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. For key outcomes (where data were available), we assessed the quality of the evidence using the GRADE approach.

Rafael Paschoal ESTEVES LIMA

Full Text Available Abstract Periodontitis can contribute to the development of insulin resistance. Gestational diabetes is a risk factor for type 2 diabetes. Therefore, periodontitis, when associated with gestational diabetes, could increase the risk for the development of type 2 diabetes after pregnancy. Objective The aim of this study was to verify the incidence on the development of type 2 diabetes in women with previous gestational diabetes with and without periodontitis after a three-year time interval. Material and Methods Initial sample of this follow-up study consisted of 90 women diagnosed with gestational diabetes who underwent periodontal examination. After three years, 49 women were subjected to new periodontal examination and biological, behavioral, and social data of interest were collected. Additionally, the quantification of the C-reactive protein in blood samples was performed. Fasting glucose and glycated hemoglobin levels were requested. Saliva samples were collected for quantification of interleukin 6 and 10, tumor necrosis factor α, matrix metalloproteinase 2 and 9. Results The incidence of type 2 diabetes mellitus was 18.4% and of periodontitis was 10.2%. There was no significant difference in the incidence of type 2 diabetes mellitus among women with and without periodontitis. It was observed impact of C-reactive protein in the development of type 2 diabetes mellitus. However, it was not observed impact of periodontitis on the development of type 2 diabetes mellitus among women with previous gestational diabetes. Conclusions It was not observed impact of periodontitis on the development of type 2 diabetes among women with previous gestational diabetes. The impact of C-reactive protein in the development of type 2 diabetes mellitus highlights the importance of an inflammatory process in the diabetes pathogenesis.

To determine whether a hypocaloric diet alone (WL) or with exercise training (AEX + WL) is effective in improving body composition, fitness, glucose utilization and CVD risk factors in sedentary women with a history of gestational diabetes (GDM) and with type 2 diabetes (T2DM). Longitudinal clinical investigation of 25 overweight/obese (BMI: 32 ± 1 kg/m(2)) women (59 ± 1 yrs) with a GDM history (n = 20) or T2DM (n = 5). Women completed 6 months WL (n = 10) or AEX+WL (n = 15) with VO2max, body composition, and glucose tolerance testing. Insulin sensitivity was measured during the last 30 min of 2 h hyperinsulinemic-euglycemic clamps (40 mU·m(-2.)min(-1)) before and after interventions. Body weight decreased ~7% after WL and AEX+WL (p exercise program combined with moderate weight loss reduces body weight, visceral and subcutaneous abdominal fat, and improves insulin sensitivity in older women who had previously been diagnosed with GDM and those with T2DM. These findings should encourage women with a history of GDM to engage in an active lifestyle and reduce caloric intake to lower the risk for the development of T2DM.

Women with insulin-requiring gestational diabetes mellitus (GDM) are at high risk of developing diabetes within a few years postpartum. We implemented this phase II study to test the hypothesis that vildagliptin, a dipeptidyl peptidase-4 inhibitor, is superior to placebo in terms of reducing the risk of postpartum diabetes. Women with insulin-requiring GDM were randomized to either placebo or 50 mg vildagliptin twice daily for 24 months followed by a 12-month observation period (EudraCT: 2007-000634-39). Both groups received lifestyle counseling. The primary efficacy outcomes were the diagnosis of diabetes (American Diabetes Association (ADA) criteria) or impaired fasting glucose (IFG)/impaired glucose tolerance (IGT). Between 2008 and 2015, 113 patients (58 vildagliptin, 55 placebo) were randomized within 2.2-10.4 (median 8.6) months after delivery. At the interim analysis, nine diabetic events and 28 IFG/IGT events had occurred. Fifty-two women withdrew before completing the treatment phase. Because of the low diabetes rate, the study was terminated. Lifestyle adherence was similar in both groups. At 24 months, the cumulative probability of postpartum diabetes was 3% and 5% (hazard ratio: 1.03; 95% confidence interval: 0.15-7.36) and IFG/IGT was 43% and 22% (hazard ratio: 0.55; 95% confidence interval: 0.26-1.19) in the placebo and vildagliptin groups, respectively. Vildagliptin was well tolerated with no unexpected adverse events. The study did not show significant superiority of vildagliptin over placebo in terms of reducing the risk of postpartum diabetes. However, treatment was safe and suggested some improvements in glycemic control, insulin resistance, and β-cell function. The study identified critical issues in performing clinical trials in the early postpartum period in women with GDM hampering efficacy assessments. With this knowledge, we have set a basis for which properly powered trials could be performed in women with recent GDM. TRIAL REGISTRATION

Gestational diabetes mellitus is a growing public health concern due to its large disease burden; however, the underlying pathophysiology remains unclear. Therefore, we examined the relationship between 107 single-nucleotide polymorphisms in insulin signalling pathway genes and gestational diabetes mellitus risk using a nested case-control study. The SOS1 rs7598922 GA and AA genotype were statistically significantly associated with reduced gestational diabetes mellitus risk ( p trend  = 0.0006) compared with GG genotype. At the gene level, SOS1 was statistically significantly associated with gestational diabetes mellitus risk after adjusting for multiple comparisons. Moreover, AGGA and GGGG haplotypes in SOS1 gene were associated with reduced risk of gestational diabetes mellitus. Our study provides evidence for an association between the SOS1 gene and risk of gestational diabetes mellitus; however, its role in the pathogenesis of gestational diabetes mellitus will need to be verified by further studies.

Full Text Available Introduction & Objective: High levels of homocystein are a risk factor for insulin resistance, diabetes mellitus and cardio-vascular complications. This study was done to assess serum homocystein and folic acid levels and their relationship in women with gestational diabetes and compare them with normal pregnant women. Materials & Methods: This analytic epidemiologic case-control study was performed in Qazvin Kosar hospital in 2013-2015. 120 singleton pregnant women with 24-28 weeks of gestation according to 2-hour 75g oral glucose tolerance test were assigned to two groups; gestational diabetes (n=60, and normal pregnancy (n=60. Serum homocystein and folic acid levels were measured in two groups. Data were analyzed with statistical t-test and correlation method. Results: In gestational diabetes serum homocystein level was significantly higher (P<0.001 and folic acid was significantly lower (P<0.001 than normal pregnancy group .No relation-ship was observed between serum homocystein and serum folate. In both groups, serum folic acid was significantly related to fasting blood sugar. This relationship was inverse in gesta-tional diabetes group (P<0.001, r = - 0.512 and direct in normal pregnancy group (P=0.001 r =0.417. Conclusion: It seems folic acid has a role in regulation of serum homocystein level and blood sugar.(Sci J Hamadan Univ Med Sci 2015; 22 (2: 93-98

Full Text Available Arachidonic acid (AA; C20∶4 n-6 and docosahexaenoic acid (DHA; C22∶6 n-3 are important long-chain polyunsaturated fatty acids (LC-PUFA in maintaining pancreatic beta-cell structure and function. Newborns of gestational diabetic mothers are more susceptible to the development of type 2 diabetes in adulthood. It is not known whether low circulating AA or DHA is involved in perinatally "programming" this susceptibility. This study aimed to assess whether circulating concentrations of AA, DHA and other fatty acids are associated with fetal insulin sensitivity or beta-cell function, and whether low circulating concentrations of AA or DHA are involved in compromised fetal insulin sensitivity in gestational diabetic pregnancies.In a prospective singleton pregnancy cohort, maternal (32-35 weeks gestation and cord plasma fatty acids were assessed in relation to surrogate indicators of fetal insulin sensitivity (cord plasma glucose-to-insulin ratio, proinsulin concentration and beta-cell function (proinsulin-to-insulin ratio in 108 mother-newborn pairs. Cord plasma DHA levels (in percentage of total fatty acids were lower comparing newborns of gestational diabetic (n = 24 vs. non-diabetic pregnancies (2.9% vs. 3.5%, P = 0.01. Adjusting for gestational age at blood sampling, lower cord plasma DHA levels were associated with lower fetal insulin sensitivity (lower glucose-to-insulin ratio, r = 0.20, P = 0.036; higher proinsulin concentration, r = -0.37, P <0.0001. The associations remained after adjustment for maternal and newborn characteristics. Cord plasma saturated fatty acids C18∶0 and C20∶0 were negatively correlated with fetal insulin sensitivity, but their levels were not different between gestational diabetic and non-diabetic pregnancies. Cord plasma AA levels were not correlated with fetal insulin sensitivity.Low circulating DHA levels are associated with compromised fetal insulin sensitivity, and may be involved in

Several commercial insulin preparations were found to contain significant quantities of pancreatic glucagon, pancreatic polypeptide (P.P.), vasoactive intestinal peptide (V.I.P.), and somatostatin, though these substances were effectively absent from the new highly purified or monocomponent insulins. Of 448 insulin-dependent diabetics receiving conventional insulins, 63% had circulating antibodies to human P.P., 6% antibodies to V.I.P., 6% to glucagon, and 0.5% to somatostatin. The antibodies were of high affinity and were commonest in the younger diabetics. No antibodies were detected in 167 maturity-onset diabetics, in 125 healthy controls, or in 22 patients treated only with monocomponent insulin. Immuno-cytochemical testing showed that antibody-positive diabetic plasmas reacted specifically against the corresponding hormone-producing pancreatic endocrine cells, against enteroglucagon and somatostatin cells outside the pancreas, and against V.I.P.-containing autonomic nerves throughout the body. The finding of iatrogenic autoimmunity to naturally occurring hormones in large numbers of insulin-dependent diabetics raises important questions about long-term treatment. (author)

Full Text Available The effects of pregestational and gestational low-to-moderate physical training on insulin secretion in undernourished mothers were evaluated. Virgin female Wistar rats were divided into four groups as follows: control (C, n=5; trained (T, n=5; low-protein diet (LP, n=5; trained with a low-protein diet (T + LP, n=5. Trained rats ran on a treadmill over a period of 4 weeks before mate (5 days week−1 and 60 min day−1, at 65% of VO2max. At pregnancy, the intensity and duration of the exercise were reduced. Low-protein groups were provided with an 8% casein diet, and controls were provided with a 17% casein diet. At third day after delivery, mothers and pups were killed and islets were isolated by collagenase digestion of pancreas and incubated for a further 1 h with medium containing 5.6 or 16.7 mM glucose. T mothers showed increased insulin secretion by isolated islets incubated with 16.7 mM glucose, whereas LP group showed reduced secretion of insulin by isolated islets when compared with both C and LP + T groups. Physical training before and during pregnancy attenuated the effects of a low-protein diet on the secretion of insulin, suggesting a potential role for compensation of insulin resistance and preventing gestational diabetes mellitus.

To investigate the association between chemerin level in the first trimester of pregnancy and the risk of gestational diabetes mellitus. The blood samples of 212 women at 8-12 weeks of gestation were collected. After screening for gestational diabetes mellitus (GDM), 19 women with GDM and 20 women randomly selected from 144 women with normal glucose tolerance (NGT) were included in the study. Blood samples were collected from these women. Triglycerides, glucose, total cholesterol, and HDL cholesterol, LDL cholesterol, insulin and chemerin were measured. Gestational weight gain and body mass index was assessed. Serum levels of chemerin were significantly elevated during late gestation, and the risk of GDM was positively associated with maternal serum chemerin in the first trimester. Serum chemerin level during the first trimester of pregnancy has the potential to predict risk of GDM.

Gestational diabetes mellitus (GDM), defined as any degree of glucose intolerance with onset or first recognition during pregnancy, is characterized by underlying maternal defects in the β-cell response to insulin during pregnancy. Women with a previous history of GDM have a greater than 7-fold higher risk of developing postpartum diabetes compared with women without GDM. Various risk factors for postpartum diabetes have been identified, including maternal age, glucose levels in pregnancy, family history of diabetes, pre-pregnancy and postpartum body mass index, dietary patterns, physical activity, and breastfeeding. Genetic studies revealed that GDM shares common genetic variants with type 2 diabetes. A number of lifestyle interventional trials that aimed to ameliorate modifiable risk factors, including diet, exercise, and breastfeeding, succeeded in reducing the incidence of postpartum diabetes, weight retention, and other obesity-related morbidities. The present review summarizes the findings of previous studies on the incidence and risk factors of postpartum diabetes and discusses recent lifestyle interventional trials that attempted to prevent postpartum diabetes.

To investigate whether baseline triglyceride levels are associated with early glucose dysregulation and/or cardiovascular risk in women with a previous history of gestational diabetes. Prospective postpregnancy cohort study. Polish university hospitals. Participants included 125 women with previous gestational diabetes and 40 women with normal glucose regulation during pregnancy. All women were studied 2-24 months (mean 12 ± 10 months) after the index pregnancy. Women with previous gestational diabetes were divided into tertiles in accordance with baseline triglyceride levels. We assessed glucose regulation (oral glucose tolerance test), insulin resistance (homeostasis model assessment), markers of endothelial dysfunction (soluble: intercellular adhesion molecule-1, vascular cell adhesion molecule-1, E-selectin, tissue plasminogen activator antigen, von Willebrand factor antigen), fibrinolysis (plasminogen activator inhibitor antigen), inflammation (high-sensitivity C-reactive protein) and lipid levels. Women with previous gestational diabetes (78% normal glucose regulation, 22% impaired glucose tolerance) had a high cardiometabolic risk profile compared with control women (100% normal glucose regulation). Baseline triglycerides >0.83 mmol/l were associated with a higher prevalence of impaired glucose tolerance, higher high-sensitivity C-reactive protein and triglyceride/high-density lipoprotein-cholesterol ratio. Triglycerides >1.22 mmol/l were associated with higher body fat indexes, higher insulin resistance, higher levels of endothelial dysfunction biomarkers, higher plasminogen activator inhibitor antigen and dyslipidemia. Only E-selectin was independently associated with triglyceride levels. Baseline triglyceride levels are a cardiovascular risk marker as well as a pathophysiological parameter independently associated with endothelial dysfunction in nondiabetic women with previous gestational diabetes at 2-24 months after an index pregnancy.

To determine the perception of insulin therapy by patients with uncontrolled type2 diabetes mellitus, who have been treated with oral hypoglycaemic agents or insulin. Prospective comparative cross-sectional study. Family Medicine Unit No. 53 León, Guanajuato of Mexican Institute of Social Security. Patients between 40 and 80years old with uncontrolled type2 mellitus diabetes, treated with insulin or oral hypoglycaemic agents. Perception was assessed using the insulin treatment appraisal scale (ITAS). The rating of the survey is from 20 to 100 points, as such that when score increases the greater is the negative opinion. A sample of 459 diabetes patients were interviewed and split into 2 groups of patients according to their treatment. The OH group were patients treated with oral hypoglycaemic drugs only (56.9%), and the IN group were patients treated with insulin alone or combined with an oral hypoglycaemic (43.1%). Perception score was significantly higher in OH group (56.95±7.78 versus 49.55±8.89 points) than in the IN group (P1). The perception of insulin therapy was worse in patients treated with only oral hypoglycaemic agents than in patients using insulin. Copyright © 2016 Elsevier España, S.L.U. All rights reserved.

Full Text Available Diabetes mellitus (DM is one of the most prevalent metabolic disorders which can affect the quality of life severely. Injectable insulin is currently being used to treat DM which is mainly associated with patient inconvenience. Small molecules that can act as insulin receptor (IR agonist would be better alternatives to insulin injection. Herein, ten bioactive small compounds derived from Gymnema sylvestre (G. sylvestre were chosen to determine their IR binding affinity and ADMET properties using a combined approach of molecular docking study and computational pharmacokinetic elucidation. Designing structural analogues were also performed for the compounds associated with toxicity and less IR affinity. Among the ten parent compounds, six were found to have significant pharmacokinetic properties with considerable binding affinity towards IR while four compounds were associated with toxicity and less IR affinity. Among the forty structural analogues, four compounds demonstrated considerably increased binding affinity towards IR and less toxicity compared with parent compounds. Finally, molecular interaction analysis revealed that six parent compounds and four analogues interact with the active site amino acids of IR. So this study would be a way to identify new therapeutics and alternatives to insulin for diabetic patients.

GDM is associated with various challenges in terms of care and public health. The present study aimed to investigate the effects of health education and behavioral interventions on the quality of life in the patients diagnosed with gestational diabetes mellitus (GDM. Methods: This randomized controlled trial was conducted on 149 eligible participants, who were randomly assigned to the intervention and control group with the allocation ratio of 1:1. Participants were divided into four groups, including nutrition therapy with and without education and insulin therapy with and without education. Follow-up of the patients was performed during 12 weeks (January 2014-April 2015. The educational intervention consisted of various aspects, including diet, exercise, glycemic control, postpartum diabetes control and recommendations for delivery. Primary and secondary outcomes were the effects of the educational intervention on the metabolic control and quality of life, respectively. All the women completed the Iranian version of the Diabetes Quality of Life Brief Clinical Inventory (IDQL-BCI prior to and after the educational intervention. Data analysis was performed using variance, covariance and Chi-square in SPSS version 15, at the significance level of 0.05. Results: No significant difference was observed between the four groups in terms of the quality of life score in the DQOL-BCL before the educational program. However, this score increased in all study groups, especially in the insulin therapy group (mean difference=16.43. Conclusion: According to the results, health education program could be effective in enhancing health-related quality of life in the women with GDM.

Diabetic peripheral neuropathy is a common and debilitating complication of diabetes mellitus. Although strict glycaemic control may reduce the risk of developing diabetic peripheral neuropathy, the neurological benefits of different insulin regimens remain relatively unknown. In the present study, 55 consecutive patients with type 1 diabetes mellitus underwent clinical neurological assessment. Subsequently, 41 non-neuropathic patients, 24 of whom were receiving multiple daily insulin injections (MDII) and 17 receiving continuous subcutaneous insulin infusion (CSII), underwent nerve excitability testing, a technique that assesses axonal ion channel function and membrane potential in human nerves. Treatment groups were matched for glycaemic control, body mass index, disease duration and gender. Neurophysiological parameters were compared between treatment groups and those taken from age and sex-matched normal controls. Prominent differences in axonal function were noted between MDII-treated and CSII-treated patients. Specifically, MDII patients manifested prominent abnormalities when compared with normal controls in threshold electrotonus (TE) parameters including depolarizing TE(10-20ms), undershoot and hyperpolarizing TE (90-100 ms) (P type 1 diabetes is maintained within normal limits in patients treated with continuous subcutaneous insulin infusion and not with multiple daily insulin injections. This raises the possibility that CSII therapy may have neuroprotective potential in patients with type 1 diabetes. Copyright © 2014 John Wiley & Sons, Ltd.

Does exercise improve postprandial glycaemic control in women diagnosed with gestational diabetes mellitus? A systematic review of randomised trials. Pregnant women diagnosed with gestational diabetes mellitus. Exercise, performed more than once a week, sufficient to achieve an aerobic effect or changes in muscle metabolism. Postprandial blood glucose, fasting blood glucose, glycated haemoglobin, requirement for insulin, adverse events and adherence. This systematic review identified eight randomised, controlled trials involving 588 participants; seven trials (544 participants) had data that were suitable for meta-analysis. Five trials scored ≥ 6 on the PEDro scale, indicating a relatively low risk of bias. Meta-analysis showed that exercise, as an adjunct to standard care, significantly improved postprandial glycaemic control (MD -0.33mmol/L, 95% CI -0.49 to -0.17) and lowered fasting blood glucose (MD -0.31 mmol/L, 95% CI -0.56 to -0.05) when compared with standard care alone, with no increase in adverse events. Effects of similar magnitude were found for aerobic and resistance exercise programs, if performed at a moderate intensity or greater, for 20 to 30minutes, three to four times per week. Meta-analysis did not show that exercise significantly reduced the requirement for insulin.

We investigated the insulin-receptor-binding effect of Scoparia dulcis plant extract in streptozotocin (STZ)-induced male Wistar rats, using circulating erythrocytes (ER) as a model system. An aqueous extract of S dulcis plant (SPEt) (200 mg/kg body weight) was administered orally. We measured blood levels of glucose and plasma insulin and the binding of insulin to cell-membrane ER receptors. Glibenclamide was used as standard reference drug. The mean specific binding of insulin to ER was significantly lower in diabetic control rats (DC) (55.0 +/- 2.8%) than in SPEt-treated (70.0 +/- 3.5%)- and glibenclamide-treated (65.0 +/- 3.3%) diabetic rats, resulting in a significant decrease in plasma insulin. Scatchard plot analysis demonstrated that the decrease in insulin binding was accounted for by a lower number of insulin receptor sites per cell in DC rats when compared with SPEt- and glibenclamide-treated rats. High-affinity (Kd1), low-affinity (Kd2), and kinetic analysis revealed an increase in the average receptor affinity in ER from SPEt and glibenclamide treated diabetic rats having 2.5 +/- 0.15 x 10(10) M(-1) (Kd1); 17.0 +/- 1.0 x 10(-8) M(-1) (Kd2), and 2.0 +/- 0.1 x 10(-10) M(-1) (Kd1); 12.3 +/- 0.9 x 10(-8) M(-1) (Kd2) compared with 1.0 +/- 0.08 x 10(-10) M(-1) (Kd1); 2.7 +/- 0.25 x 10(-8) M(-1) (Kd2) in DC rats. The results suggest an acute alteration in the number of insulin receptors on ER membranes in STZ-induced diabetic rats. Treatment with SPEt and glibenclamide significantly improved specific insulin binding, with receptor number and affinity binding (p < 0.001) reaching almost normal non-diabetic levels. The data presented here show that SPEt and glibenclamide increase total ER membrane insulin binding sites with a concomitant significant increase in plasma insulin.

To investigate whether the presence of glutamic acid decarboxylase (GAD) autoantibodies post-partum in women with prior gestational diabetes mellitus was associated with changes in metabolic characteristics, including β-cell function and insulin sensitivity. During 1997-2010, 407 women with gestational diabetes mellitus were offered a 3-month post-partum follow-up including anthropometrics, serum lipid profile, HbA1c and GAD autoantibodies, as well as a 2-h oral glucose tolerance test (OGTT) with blood glucose, serum insulin and C-peptide at 0, 30 and 120 min. Indices of insulin sensitivity and insulin secretion were estimated to assess insulin secretion adjusted for insulin sensitivity, disposition index (DI). Twenty-two (5.4%) women were positive for GAD autoantibodies (GAD+ve) and the remainder (94.6%) were negative for GAD autoantibodies (GAD-ve). The two groups had similar age and prevalence of diabetes mellitus. Women who were GAD+ve had significantly higher 2-h OGTT glucose concentrations during their index-pregnancy (10.5 vs. 9.8 mmol/l, P = 0.001), higher fasting glucose (5.2 vs. 5.0 mmol/l, P = 0.02) and higher 2-h glucose (7.8 vs. 7.1 mmol/l, P = 0.05) post-partum. Fasting levels of C-peptide and insulin were lower in GAD+ve women compared with GAD-ve women (520 vs. 761 pmol/l, P = 0.02 and 33 vs. 53 pmol/l, P = 0.05) Indices of insulin sensitivity were similar in GAD+ve and GAD-ve women, whereas all estimates of DI were significantly reduced in GAD+ve women. GAD+ve women had higher glucose levels and impaired insulin secretion adjusted for insulin sensitivity (DI) compared with GAD-ve women. The combination of OGTT and GAD autoantibodies post-partum identify women with impaired β-cell function. These women should be followed with special focus on development of Type 1 diabetes. © 2014 The Authors. Diabetic Medicine © 2014 Diabetes UK.

Gestational diabetes mellitus (GDM) has become a serious health risk among pregnant women throughout the world. Phytosterol-enriched margarines are capable of lowering total cholesterol (TC) and low-density lipoprotein (LDL), but little is known about its effects on GDM. We aimed to examine the effects of daily consumption of a phytosterol-enriched spread on insulin resistance and lipid profile in pregnant GDM women. Pregnant women suffering from GDM in their second trimester were recruited and randomly assigned to consume a margarine spread either with or without phytosterols daily for 16 weeks. Serum lipid profile and glucose and insulin metabolisms were assessed at week 0 (baseline) and week 16 (end of trial). After 16 weeks, levels of triacylglycerol, TC, and LDL were significantly decreased, while high-density lipoprotein was significantly increased, compared with the baseline in the phytosterol group. In addition, in the same treatment group, glucose metabolic parameters, including fasting plasma glucose, serum insulin levels, the quantitative insulin check index, homeostasis model of assessment of insulin resistance, and β-cell function, were also significantly improved. Daily consumption of a phytosterol-enriched spread improved insulin resistance and lipid profile in women with GDM.

Full Text Available Objective The aim of the present study was to determine differences between male and female type 2 diabetic patients concerning body weight, metabolic control, insulin requirement and prevalence of vascular diseases during the first year insulin therapy. Patients and Methods We investigated 102 newly insulin-treated type 2 diabetic patients (60 female with secondary sulfonylurea failure. Observation period was the first year insulin therapy. We compared BMI, HbA1c, lipids and insulin requirement at the begin and after one year, C-peptide and prevalence of vascular diseases at the start of insulin therapy. Results At the start of insulin substitution, omen had a higher BMI (27 + 3 versus 25 + 3; p < 0.05. Women also required a higher insulin dose than did men (28 + 6 versus 24 + 6 IU/day Mean HbA1c and cholesterol levels were similar in both groups whereas triglycerides were higher in women (244 + 88 versus 203 + 76 mg/dl; p < 0.05. Both groups achieved a similar gain in body weight after one year (+2.5% versus +2.6%; NS. HbA1c decreased from 9.2 + 1.1 to 7.4% + 0.9% (–19% in women and from 9.4 + 1.1 to 7.5% + 1.0% (–20% in men. The prevalence of vascular diseases was not significantly different in both groups. Conclusions At the start of insulin therapy female type 2 diabetic patients showed a significant higher BMI and a higher insulin requirement than male patients. The metabolic control was similar in men and women, only the triglycerides were higher in the female patients. Weight gain and increase of needed insulin as well as prevalence of macroangiopathy were the same in both groups.

Full Text Available Introduction: Gestational diabetes mellitus (GDM is defined as any degree of glucose intolerance with onset or first recognition during pregnancy.[1] Pregnancy is a unique situation in which there is a physiological temporary increase in insulin resistance (IR. The mechanisms responsible for the gestational-induced IR are not completely understood. The current study was undertaken to compare adiponectin levels during 24–28 weeks period of gestation in drug-naive newly diagnosed GDM women with a cohort of normoglycemic pregnant women. Subjects and Methods: A total of 47 pregnant women in the age group of 18–40 years were included in this cross-sectional study, of which 13 were GDM cases and 34 were normoglycemic controls. Serum adiponectin level was analyzed by enzyme-linked immunosorbent assay. Results: The mean adiponectin level was 16.92 ng/ml (standard deviation [SD] = 2.78 and 19.38 ng/ml (SD = 2.71 in case and control groups, respectively, and the difference was found to be statistically significant (P = 0.008. Conclusion: Our study demonstrated decreased serum adiponectin levels in women with GDM when compared with age- and body mass index-matched euglycemic pregnant women.

Full Text Available The blood serum lipid profile of women with Gestational Diabetes Mellitus (GDM is still under study. There are no data on the serum lipid profile of GDM patients with more severe (insulin treated compared to milder forms (diet treated GDM. The aim of our study was to analyze the blood serum lipid profile of patients with milder versus more severe forms of GDM and to compare these findings with those of healthy pregnant women. This cross-sectional analytical study included 30 insulin-treated GDM, 30 diet-only GDM and 30 healthy pregnant women. Serum lipid was extracted from the 90 participants and their lipid profiles were analyzed by lipid fingerprinting using liquid-chromatography-mass spectrometry. A total of 143 parent ions were differentially represented in each of the three groups, belonging to the following classes: Glycerophospholipids, Sterol Lipids, Sphingolipids, Prenol Lipids, Fatty Acyls and Glycerolipids. There were significant differences in the lipid profiles of healthy pregnant women compared to GDM patients and also between milder versus more severe forms of GDM. There are marked differences in lipid fingerprinting between healthy pregnant women compared to those with GDM in the third trimester. Moreover, the lipid profile of women with more severe forms of GDM differs considerably from that of women with milder forms of GDM. These findings may be useful to help clarify the pathogenesis of milder and more severe forms of GDM.

INTRODUCTION: Pregnancy is associated with decreased insulin sensitivity, which is usually overcome by a compensatory increase in insulin secretion. Some pregnant women are not able to increase their insulin secretion sufficiently, and consequently develop gestational diabetes mellitus (GDM......). The disease normally disappears after delivery. Nevertheless, women with previous GDM have a high risk of developing type 2 diabetes (T2D) later in life. We aim to investigate the early development of T2D in women with previous GDM and to evaluate whether treatment with the glucagon-like peptide-1 receptor...

The timely onset of stage II lactogenesis (OL) is important for successful breastfeeding and newborn health. Several risk factors for delayed OL are common in women with a history of gestational diabetes mellitus (GDM), which may affect their chances for successful breastfeeding outcomes. We investigated the prevalence and risk factors associated with delayed OL in a racially and ethnically diverse cohort of postpartum women with recent GDM. We analyzed data collected in the Study of Women, Infant Feeding and Type 2 Diabetes After GDM Pregnancy (SWIFT), which is a prospective cohort of women diagnosed with GDM who delivered at Kaiser Permanente Northern California hospitals from 2008 to 2011. At 6-9 wk postpartum, delayed OL was assessed by maternal report of breast fullness and defined as occurring after 72 h postpartum. We obtained data on prenatal course and postdelivery infant feeding practices from electronic medical records and in-person surveys. We used multivariable logistic regression models to estimate associations of delayed OL with prenatal, delivery, and postnatal characteristics. The analysis included 883 SWIFT participants who initiated breastfeeding and did not have diabetes at 6-9 wk postpartum. Delayed OL was reported by 33% of women and was associated with prepregnancy obesity (OR: 1.56; 95% CI: 1.07, 2.29), older maternal age (OR: 1.05; 95% CI: 1.01, 1.08), insulin GDM treatment (OR: 3.11; 95% CI: 1.37, 7.05), and suboptimal in-hospital breastfeeding (OR: 1.65; 95% CI: 1.20, 2.26). A higher gestational age was associated with decreased odds of delayed OL but only in multiparous mothers (OR: 0.79; 95% CI: 0.67, 0.94). One-third of women with recent GDM experienced delayed OL. Maternal obesity, insulin treatment, and suboptimal in-hospital breastfeeding were key risk factors for delayed OL. Early breastfeeding support for GDM women with these risk factors may be needed to ensure successful lactation. This trial was registered at clinicaltrials

Full Text Available There is no doubt that behavioral intervention is crucial for type 2 diabetes mellitus (T2DM prevention and management. We aimed to estimate dietary habits and diet-oriented knowledge as well as the level of physical activity in 2500 insulin-treated Polish type 2 diabetes mellitus (T2DM patients (55.4% women. The mean age of the study participants was 64.9 ± 9.3 years, mean BMI was 31.4 kg/m2 ± 4.5, mean diabetes duration was 12.4 ± 6.9 years, and mean baseline HbA1c was 8.5%  ± 1.2. At the study onset, all the patients completed a questionnaire concerning health-oriented behavior. Results showed a significant lack of diet-related knowledge. For example, only 37.5% recognized that buckwheat contains carbohydrates; the percentage of correct answers in questions about fruit drinks and pasta was 56.4% and 61.2%, respectively. As for the physical activity, only 57.4% of examined T2DM patients declared any form of deliberate physical activity. To conclude, the cohort of poorly controlled insulin-treated T2DM patients studied by us is characterized by insufficient diet-related knowledge and by a very low level of physical activity. Further studies on other populations of insulin-treated T2DM patients are required to confirm these findings.

Diabetes is one of the most common metabolic disorders that may cause pathological pregnancy. Treating diabetes recognized during pregnancy results in lowering maternal and fetal complications. These patients present higher risk for excessive weight gain, preeclampsia, delivery with cesarean sections, high risk of developing type 2 diabetes and cardiovascular disease in the future. Fetuses of mothers with gestational diabetes are at higher risk for macrosomia and birth trauma, after delivery they present higher risk of developing neonatal hypoglycemia, hyperbilirubinemia, and respiratory distress syndrome. There is still no consensus in the recommendations for the diagnosis of gestational diabetes mellitus by expert committees. Orv. Hetil., 2017, 158(8), 283-290.

Dyslipidemia, a major risk factor for cardiovascular disease is a common finding in patients with type 2 diabetes and among women with gestational diabetes. Elevated levels of lipoprotein(a) [Lp(a)] are linked to increased risk of cardiovascular disease. However, its relationship with insulin resistance, type 2 diabetes and gestational diabetes is controversial and unproven. Here we aimed to clarify whether Lp(a) levels are associated with insulin sensitivity in pregnancy. Sixty-four women with gestational diabetes and 165 with normal glucose tolerance were enrolled in the study. Fasting Lp(a) serum levels were measured in all women at 24-28 weeks of gestation. In pregnancy, there was no significant difference in serum Lp(a) concentrations between the two groups. Its level did not correlate with markers of insulin resistance (HOMA-IR), insulin sensitivity (HOMA-S%), pancreatic beta-cell function (HOMA-B%) and insulin sensitivity in dynamic conditions (OGIS). In addition, fasting glucose and insulin levels and those throughout an oral glucose tolerance test were independent of Lp(a) concentrations in our study group. Lp(a) levels in pregnant women do not differ with respect to the presence or absence of gestational diabetes. Although influenced by some components of the lipid profile, such as triglycerides and HDL-C, insulin resistance in pregnancy is not affected by Lp(a).

Full Text Available "nBackground: Maternal zinc deficiency during pregnancy has been related to adverse pregnancy outcomes. Most studies in which pregnant women have been supplemented with zinc to examine its effects on the outcome of the pregnancy have been carried out in industrialized countries and the results have been inconclusive. It has been shown that women with gestational diabetes (GDM have lower serum zinc levels than healthy pregnant women, and higher rates of macrosomia. Zinc is required for normal glucose metabolism, and strengthens the insulin-induced transportation of glucose into cells by its effect on the insulin signaling pathway. The purpose of this study was to assess the serum zinc levels of GDM patients and evaluate the effect of zinc supplementation. "nMethods: In the first stage of this prospective controlled study, we enrolled 70 women who were 24-28 weeks pregnant at the Prenatal Care Center of Mirza Kochak Khan Hospital, Tehran, Iran. The serum zinc level of each subject was determined. In the second stage, among these 70 subjects, the diabetics receiving insulin were divided into two groups, only one of which received a zinc supplement and the other group was the control group. Birth weight of neonates and insulin dosages were recorded. "nResults: The mean serum zinc level in the GDM group was lower than that of the control group (94.83 vs. 103.49mg/dl, respectively and the mean birth weight of neonates from the GDM women who received the zinc supplement was lower than that of the control group (3849g vs. 4136g. The rate of macrosomia was lower in the zinc supplemented group (20% vs. 53%. The mean of increase of insulin after receiving the zinc supplement was lower (8.4u vs. 13.53. "nConclusion: Maternal insulin resistance is associated with the accumulation of maternal fat tissue during early stages of pregnancy and greater fetoplacental nutrient availability in later stages, when 70% of fetal growth occurs, resulting in macrosomia.

Ten dogs with naturally occurring diabetes mellitus were injected with a highly purified porcine insulin zinc suspension at a dose according to their expected requirement. Plasma insulin and glucose concentrations were measured at two-hourly intervals over 24 hours following injection. There were either one or two peaks in plasma insulin concentration: one at about four hours (mean 4.3 +/- 1.3 [SD]) and another at about 11 hours (mean 11 +/- 1.85) after the injection. The second insulin peak was seen in only eight dogs. Persistence of elevated plasma insulin concentrations ranged from 14 to 24 hours (mean 17.4 +/- 3.65). These results compare favourably with those published for other intermediate-acting insulin preparations used to treat canine diabetes mellitus and suggest that this preparation has useful properties for the successful management of many canine diabetics.

Gestational diabetes mellitus (GDM) predisposes women to future development of Type 2 diabetes mellitus (DM2) and the two conditions share similar metabolic alterations. Recent observations suggest that a defective glucose stimulated insulin secretion by glucagon-like peptide-1 (GLP- 1) plays a role in the pathogenesis of DM2. Whether such a defect is impaired in GDM remains to be ascertained. We have determined GLP-1 secretion in response to oral glucose tolerance test (OGTT) in GDM and normal glucose tolerance (NGT) during and after pregnancy. 100-g-3h OGTT was performed in 12 GDM and 16 NGT women at 27.3 ± 4.1 weeks of gestation, for determination of plasma GLP-1, glucose, insulin, and C-peptide. Insulin sensitivity (ISI) and insulin secretion (first and second phase); as well as ISI-secretion index (ISSI) were also derived. NGT and GDM women were comparable for age pre-pregnancy body mass index (BMI) and weight gain. GDM had higher glucose area under the curve (AUC): 27,575.5 ± 3448 vs 20,685.88 ± 2715 mg/dl min (pwomen (2542 ± 273 vs 10,092 ± 7367 pmol·l-1·min-1, pwomen is inadequate for the prevailing glycemic levels both in pregnancy and post partum. Moreover, we cannot exclude that other important aspects of the incretin effect may be involved in GDM development.

Full Text Available Objective This study aims to investigate predictive risk factors in the treatment of gestational diabetes mellitus (GDM. Patients and Methods A total of 256 pregnant women who underwent 75 g oral glucose tolerance test (OGTT during 24–28 weeks of pregnancy were included according to the World Health Organization criteria. Demographic characteristics of the patients, including age, parity, family history of diabetes, body weight before pregnancy, and body weight at the diagnosis of GDM, were recorded. Fasting insulin and hemoglobin A1c (HbA1c values at the time of diagnosis were evaluated. The patients were divided into two groups: those requiring insulin treatment (insulin group, n = 89 and those receiving diet therapy (diet group, n = 167 during pregnancy according to the American Diabetes Association recommendations. Results A total of 34.76% of the pregnant women with GDM required insulin treatment. The mean age of these patients was significantly higher compared to the diet group (34.9 ± 0.6 years vs. 31.9 ± 0.6 years; P = 0.004. Body mass index before pregnancy was also significantly higher in the insulin group than that in the diet group (32 ± 0.9 kg/m 2 vs. 29 ± 0.7 kg/m 2 ; P = 0.004.

Insulin therapies with prandial injections offer the possibility to skip snacks or omit meals. It is unclear how many people with insulin-treated diabetes mellitus eat snacks and whether they snack for their own comfort or only on the recommendation of healthcare professionals. In 2004, 163 consecutive people with insulin-treated diabetes seen in a university outpatient department were interviewed regarding their diet and degree of satisfaction with their meals. Fifty-five had Type 1 diabetes [age 47 years; diabetes duration 18 years; BMI 27 kg/m(2) ; HbA1c 62 mmol/mol (7.8%)], 53 had Type 2 diabetes with biphasic insulin therapy [age 68 years; diabetes duration 17 years; BMI 31 kg/m(2) ; HbA1c 60 mmol/mol (7.6%)] and 55 had Type 2 diabetes with prandial insulin therapy [age 60 years; diabetes duration 16 years; BMI 33 kg/m(2) ; HbA1c 59 mmol/mol (7.6%)]. Eighty per cent of those with Type 1 diabetes ate snacks, together with 77% of the Type 2 diabetes/biphasic group and 62% of the Type 2 diabetes/prandial group. Most participants (91% Type 1 diabetes, 88% Type 2 diabetes/biphasic group, 82% Type 2 diabetes/prandial group) liked to have snacks. The time at which they ate snacks was the same for both diabetes types. There were no differences between participants with Type 1 diabetes who snacked and those who did not in terms of age (P = 0.350), BMI (P = 0.368), HbA1c (P = 0.257) and time since diagnosis (P = 0.846). Participants with Type 2 diabetes who ate snacks were older than those who did not (biphasic: P = 0.006; prandial: P = 0.008). There were no differences in terms of BMI (biphasic: P = 0.731; prandial: P = 0.393), HbA1c (biphasic: P = 0.747; prandial: P = 0.616) and time since diagnosis (biphasic: P = 0.06; prandial: P = 0.620). Most people with insulin-treated diabetes eat snacks voluntarily and not because of physicians' instructions. There were no correlations between the use of snacks and HbA1c , BMI and

Omental adipose tissue plays a central role in insulin resistance in gestational diabetes mellitus (GDM), and the molecular mechanisms leading to GDM remains vague. Evidence demonstrates that maternal hormones, such as estradiol, contribute to insulin resistance in GDM. In this study we determined the differential expression patterns of microRNAs (miRNAs) in omental adipose tissues from GDM patients and pregnant women with normal glucose tolerance using AFFX miRNA expression chips. MiR-222, 1 of 17 identified differentially expressed miRNAs, was found to be significantly up-regulated in GDM by quantitative real-time PCR (P insulin-sensitive membrane transporter glucose transporter 4 (GLUT4) protein (P insulin-stimulated translocation of GLUT4 from the cytoplasm to the cell membrane and glucose uptake in mature adipocytes were dramatically increased (P insulin resistance in GDM and might be a candidate biomarker and therapeutic target for GDM.

To examine the differential effects of insulin sensitivity and secretion on hemoglobin A1c (HbA1c) and glycated albumin (GA) at 24-32weeks of pregnancy in women with gestational diabetes mellitus (GDM). A cross-sectional, sequential case series study was performed in pregnant women with an abnormal 50-g oral glucose-screening test. Hemoglobin A1c and GA measurements were taken during oral glucose tolerance test (OGTT). The homeostasis model assessment of insulin resistance (HOMA-IR) and beta-cell function (HOMA-%β), insulin sensitivity index (ISOGTT), and modified insulinogenic index were calculated to assess insulin sensitivity and secretory function. A total of 713 pregnant women were enrolled. The GDM group had lower ISOGTT and insulinogenic index scores, and a higher HOMA-IR score. Hemoglobin A1c was positively correlated with HOMA-IR. Glycated albumin was negatively correlated with insulinogenic index and HOMA-%β. Multiple regression analysis revealed that HbA1c was independently associated with diastolic pressure, 0- and 120-minute glucose, and HOMA-IR; GA was independently associated with 0- and 120-minute glucose. Compared with HbA1c, GA is more closely correlated with fasting and postprandial glucose, regardless of insulin resistance and blood pressure, and might be a better monitoring index in women with GDM.

The aim of this study was to investigate the correlations and interactions between the polymorphisms of insulin resistance-related genes (ADIPOQ rs2241766), inflammation factors (TNF-α rs1800629, IL-6 rs1800795), obesity-related genes (GNB3 rs5443, ADRB rs1042714), and risk factors for gestational diabetes mellitus (GDM) such as diet structure in the development of GDM. This research was conducted among women who visited the third-affiliate hospital of Zhengzhou University for pregnancy checkups from 1 June 2014 to 30 December 2014. Based on the results of a 75-g glucose tolerance test (OGTT), 140 pregnant women with GDM were randomly selected as a part of the GDM group and140 healthy, pregnant women as part of the control group. Relevant clinical and laboratory data for the child and the mother including her pregnancy outcomes and the delivery mode were collected for the epidemiological survey. The results showed that risk factors for GDM are advanced age, the hepatitis B virus, family history of diabetes, high body mass index before pregnancy, and weight gain of ≥10 kg before 24-week gestation. We found that diet structures were severely unbalanced. The polymorphisms rs2241766 and rs5443 were found to potentially be associated with GDM; moreover, a positive interaction was demonstrated between rs2241766 and age, and a negative interaction was demonstrated with weight gain of ≥10 kg before 24-week gestation. Our findings demonstrate that both environmental risk factors and genetic background contribute to the development of GDM.

Women with a history of gestational diabetes are at high risk for developing type 2 diabetes mellitus. In studies with long periods of follow-up, diabetes incidence of up to 70% has been reported. The appropriate follow-up of women following a pregnancy complicated by gestational diabetes has not been studied. Published guidelines recommend that obstetrician/gynaecologists, who are often the de facto primary care physicians for these otherwise healthy young women, incorporate glucose monitoring in the post-partum period into their annual examinations. In reality, reported rates of screening have been low. There is also no clear evidence for any beneficial interventions to prevent diabetes in patients with prior history of gestational diabetes. Lifestyle intervention programmes for diabetes prevention among these patients yielded disappointing results. Metformin, pioglitazone, liraglutide, and bariatric surgery are possible options but based on inadequate data. There remains a need for randomized, placebo-controlled studies to evaluate various pharmacologic treatments, with and without lifestyle interventions, to prevent type 2 diabetes mellitus in women with a history of gestational diabetes.

There is scarcity of available information on the possible significant risk factors related to diabetes mellitus (DM) prediction among expectant Saudi mothers with gestational diabetes mellitus (GDM). The present study is the first to identify such risk factors in the Arab cohort. A total of 300 pregnant subjects (mean age 33.45 ± 6.5 years) were randomly selected from all the deliveries registered at the Obstetrics Department of King Fahad Medical City, Riyadh Saudi Arabia from April 2011 to March 2013. Demographic and baseline glycemic information were collected. A total of 7 highly significant and independent risk factors were identified: age, obesity, and family history of DM, GDM < 20 weeks, macrosomia, insulin therapy and recurrent GDM. Among these factors, subjects who had insulin therapy use are 5 times more likely to develop DMT2 (p-value 3.94 × 10(-14)) followed by recurrent GDM [odds-ratio 4.69 (Confidence Interval 2.34-4.84); P = 1.24 × 10(-13)). The identification of the risk factors mentioned with their respective predictive powers in the detection of DMT2 needs to be taken seriously in the post-partum assessment of Saudi pregnant patients at highest risk.

Short-term effect of red wine (consumed during meals) on insulin requirement and glucose tolerance in diabetic patients.

To determine the effect of wine on insulin requirement or glucose tolerance. Five men with insulin-treated diabetes and 10 men with non-insulin-treated diabetes ate the same lunch with the same volume of either water or red wine (2 glasses). Insulin requirement was determined with an artificial pancreas (Biostator). Glucose tolerance was evaluated from the postprandial glycemic level. There was no significant difference in insulin requirement determined with an artificial pancreas in the insulin-treated patients after the two meals (31.5 +/- 4.21 U with water and 31.8 +/- 4.3 U with wine). Glucose tolerance in the non-insulin-treated patients was lower after the meal with wine. Moderate prandial wine consumption has no adverse effect on the glycemic control of diabetic patients. Thus, it appears unnecessary to proscribe the consumption of red wine in moderation with meals to diabetic patients. Wine contains tannins and phytates that can explain its action.

During a pregnancy complicated by diabetes, the placenta undergoes a number of functional and structural pathologic changes. However, differences across studies may reflect pathophysiologic differences of diabetes types under investigation. We examined placental pathology from women ages 18-40 years with self-identified race/ethnicity; singleton, live births; and type 1 (T1DM; n = 36), type 2 (T2DM; n = 37), or gestational diabetes mellitus (GDM; n = 126). Clinical data were abstracted from medical records. Placental diagnoses were independently re-reviewed by a perinatal pathologist. Multivariable analyses adjusting for race, gestational weight gain, gestational age, and systolic blood pressure were conducted. Women with T1DM compared with either T2DM or GDM had higher gestational weight gain (mean ± SD, T1DM vs. T2DM: 28.5 ± 12.4 vs. 20.5 ± 13.4 kg, p = 0.03; or GDM: 21.3 ± 12.7 kg, p = 0.009) and insulin use (T2DM: 100.0% vs. 85.3%, p = 0.02; or GDM: 4.0%, p diabetes type, potentially reflecting underlying pathophysiologic mechanisms. Further research on placental pathology and metabolic derangements is warranted. Copyright © 2015 Elsevier Ltd. All rights reserved.

Changes in erythrocyte insulin receptors in normal dogs and keeshond dogs with inheritable, early onset, insulin dependent diabetes mellitus

International Nuclear Information System (INIS)

Klaassen, J.K.

1986-01-01

Validation of a procedure to evaluate insulin receptors on erythrocytes (RBC-IR) in dogs is described. The specific binding of ( 125 I)iodoinsulin to RBC-IR of normal dogs is significantly greater than binding in keeshonds with an inheritable form of early onset diabetes mellitus. This decreased binding was due to a significant decrease in RBC-IR affinity in the diabetic keeshonds. To determine the effect on RBC-IR, normal dogs were treated with either dexamethasone (0.1 mg/kg) or prednisone (0.3 mg/kg) for 10 days: concentrations of plasma cortisol, glucose, and insulin, plus binding characteristics of RBC-IR were determined. In the dexamethasone treated group, plasma glucose concentrations were elevated significantly by day 6 and continued through day 10. Insulin concentrations were elevated significantly by day 3 and remained elevated through day 10. In the prednisone treated group, glucose concentrations were elevated significantly by day 3, while insulin concentrations were elevated significantly by day 8. Maximum binding of RBC-IR was unaffected by prednisone and neither affinities nor receptor numbers were significantly different from day 1. No changes in plasma cortisol concentration were seen. Diabetic keeshonds on daily insulin treatment were removed from exogenous insulin therapy for 48 hours. Significant increases in glucose concentrations were observed, but no significant changes in cortisol, insulin, average receptor binding affinity, or RBC-IR number per cell occurred

Full Text Available Objective: Recently, we have shown that Bezafibrate (BEZ, the pan-PPAR (peroxisome proliferator-activated receptor activator, ameliorated diabetes in insulin deficient streptozotocin treated diabetic mice. In order to study whether BEZ can also improve glucose metabolism in a mouse model for fatty liver and type 2 diabetes, the drug was applied to TallyHo mice. Methods: TallyHo mice were divided into an early (ED and late (LD diabetes progression group and both groups were treated with 0.5% BEZ (BEZ group or standard diet (SD group for 8 weeks. We analyzed plasma parameters, pancreatic beta-cell morphology, and mass as well as glucose metabolism of the BEZ-treated and control mice. Furthermore, liver fat content and composition as well as hepatic gluconeogenesis and mitochondrial mass were determined. Results: Plasma lipid and glucose levels were markedly reduced upon BEZ treatment, which was accompanied by elevated insulin sensitivity index as well as glucose tolerance, respectively. BEZ increased islet area in the pancreas. Furthermore, BEZ treatment improved energy expenditure and metabolic flexibility. In the liver, BEZ ameliorated steatosis, modified lipid composition and increased mitochondrial mass, which was accompanied by reduced hepatic gluconeogenesis. Conclusions: Our data showed that BEZ ameliorates diabetes probably via reduced steatosis, enhanced hepatic mitochondrial mass, improved metabolic flexibility and elevated hepatic insulin sensitivity in TallyHo mice, suggesting that BEZ treatment could be beneficial for patients with NAFLD and impaired glucose metabolism.

Women with gestational diabetes mellitus (GDM) have an increased risk of diabetes postpartum. We developed a score to predict the long-term risk of postpartum diabetes using clinical and anamnestic variables recorded during or shortly after delivery. Data from 257 GDM women who were prospectively followed for diabetes outcome over 20 years of follow-up were used to develop and validate the risk score. Participants were divided into training and test sets. The risk score was calculated using Lasso Cox regression and divided into four risk categories, and its prediction performance was assessed in the test set. Postpartum diabetes developed in 110 women. The computed training set risk score of 5 × body mass index in early pregnancy (per kg/m(2)) + 132 if GDM was treated with insulin (otherwise 0) + 44 if the woman had a family history of diabetes (otherwise 0) - 35 if the woman lactated (otherwise 0) had R (2) values of 0.23, 0.25, and 0.33 at 5, 10, and 15 years postpartum, respectively, and a C-Index of 0.75. Application of the risk score in the test set resulted in observed risk of postpartum diabetes at 5 years of 11 % for low risk scores ≤140, 29 % for scores 141-220, 64 % for scores 221-300, and 80 % for scores >300. The derived risk score is easy to calculate, allows accurate prediction of GDM-related postpartum diabetes, and may thus be a useful prediction tool for clinicians and general practitioners.

Clinical diagnosis of gestational diabetes.

Science.gov (United States)

Ryan, Edmond A

2013-12-01

Gestational diabetes mellitus (GDM) diagnosis remains controversial. ACOG criteria are based on the long-term risk of maternal diabetes. ADA recently suggested diagnosing GDM with 1 elevated value on an oral glucose tolerance test based on a 1.75-fold risk of large-for-gestational age infants resulting in a 17.8% rate of GDM. Given the lack of neonatal-based outcomes for the traditional position and problems of reproducibility and benefit/harm balance of the ADA approach, an alternative is presented herein based on a 2-fold risk of a large-for-gestational age baby, requiring 2 separate abnormalities to reduce false positives giving a more balanced benefit/harm ratio (10% GDM rate).

Glycemic Status During Pregnancy in Gestational Diabetic & Non-Gestational Diabetic Women & its Effect on Maternal & Fetal Outcome

Full Text Available Aims & Objectives: 1.To study the time course of plasma glucose, in gestational diabetic and normal pregnant women. 2.To compare maternal outcome and fetal outcome in gestational diabetic and normal pregnant women. Materials and Methods: Five hundred pregnant individuals visiting the Antenatal Clinic of Rural Medical College, Loni in either half of the gestation were screened and gestational diabetes mellitus was diagnosed according to the WHO criteria. Results: The scope of diabetes and pregnancy encompasses not only diabetics marching through pregnancy but also, any form of abnormal glucose tolerance developing during gestation, termed as gestational diabetes, abnormal glucose tolerance of any etiology recognized or unrecognized starting before pregnancy or revealed during pregnancy, is associated with a high risk of a poor maternal and fetal outcomes. In our study we found a significantly higher incidence of caesarean section in-patients with GDM when compared with the normal group (67% versus 25%, P <0.001. In GDM cases, we observed fetal macrosomia, high birth weight etc. Naturally these are the factors, which add to the pre-existing unfavourable maternal factors affecting the process of labour adversely. We observed a significant difference in the incidence of preterm labour in between the GDM and non-GDM groups (22% Vs 13%, p<0.05. These individuals underwent a process of preterm labour at a gestational age of 32+3 weeks. Hyperglycemia and polyhydramnios are held responsible for preterm labour. The incidence rate of PIH was more in subjects with GDM as compared to the other group. However this difference failed to prove statistically significant at 5% level of significance. Though we did not get a significant difference in occurrence of PIH in between the GDM and non-GDM groups, we do agree with the comment that hyperglycemia earlier in the pregnancy is associated with greater incidence of PIH as three of the four cases who were diagnosed

The role of gut microbiota in the management of diabetes is shown. In this randomized clinical trial we assessed the effects of synbiotic supplementation on insulin, lipid profile and antioxidative status among women with gestational diabetes mellitus (GDM). Ninety pregnant women with GDM were randomly assigned into two groups to receive either a daily synbiotic capsule - consisting of L. acidophilus, L. plantarum, L. fermentum, L. gasseri (1.5-7.0 × 10 9-10  CFU/g) - with fructooligosaccharide (38.5 mg), or placebo for 6 weeks. Fasting plasma glucose (FPG), insulin, homeostasis model assessment-insulin resistance (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), high- and low density lipoprotein cholesterol (HDL-C, LDL-C), total cholesterol (TC), triglycerides (TG), total antioxidant capacity (TAC), and systolic and diastolic blood pressure (SBP, DSP) were assessed before and after the intervention. No significant changes in FPG, insulin resistance/sensitivity, lipid profile and TAC indices were seen in synbiotic group compared to the placebo one (p > 0.05). Significant within group increases for HDL-C and TAC levels in synbiotic group were observed (p insulin resistance/sensitivity indices. Lipid profile and TAC status may be affected by synbiotic supplementation. Synbiotic is effective in reducing of blood pressure in women with GDM. Copyright © 2018 Elsevier B.V. All rights reserved.

2015-11-01

Gestational diabetes mellitus (GDM) is characterised by hyperglycaemia during pregnancy. The clinical circumstances involved in the development of GDM leaves the patient at a high risk of the subsequent development of type 2 diabetes. Plasma levels of the inflammation marker YKL-40 are elevated in type 2 diabetes and correlate with fasting plasma glucose levels and insulin resistance in patients with type 2 diabetes. With the present study we aimed to determine if pregnancy (and associated insulin resistance) with or without GDM affects plasma YKL-40 levels. Plasma from women diagnosed with GDM and healthy normal glucose-tolerant pregnant women (non-GDM) was obtained at the third trimester of pregnancy and again 3-4 months following delivery, and levels of YKL-40 and interleukin 6 (IL-6; known to regulate YKL-40) were measured. Plasma YKL-40 levels were similarly low during pregnancy in both groups and increased significantly after delivery, but remained lower in the GDM group compared with the non-GDM group postpartum. In contrast, plasma IL-6 levels were not affected by pregnancy or diagnosis of GDM, Nevertheless, YKL-40 levels were associated with IL-6 levels in the non-GDM group (but not in the GDM group). Pregnancy seems to be associated with a temporary reduction in circulating YKL-40, which increases after delivery, but to a much lesser extent in women with GDM than in non-GDM women.

The metabolic and hormonal adaptations to single exercise sessions and to exercise training in normal man and in patients with insulin-dependent as well as non-insulin-dependent diabetes mellitus are reviewed. In insulin-dependent (type I) diabetes good metabolic control is best obtained...... by a regular pattern of life which will lead to a fairly constant demand for insulin from day to day. Exercise is by nature a perturbation that makes treatment of diabetes difficult: Muscle contractions per se tend to decrease the plasma glucose concentration whereas the exercise-induced response of the so......-called counter-regulatory hormones tend to increase plasma glucose by increasing hepatic glucose production and adipose tissue lipolysis.

This study aimed to examine the attitudes and beliefs towards gestational diabetes of a multiethnic sample of pregnant women with gestational diabetes. Women from non-Caucasian background are disproportionately represented in gestational diabetes statistics. This is of particular importance in multicultural Australia, where increasing numbers of non-Caucasian women give birth. Cross-sectional survey. The Diabetes Attitude Scale, version 3 was administered to 200 women with gestational diabetes from Vietnamese, Indian, Filipino and Caucasian backgrounds. A total of 143 questionnaires were returned indicating a response rate of 71·5%. There were significant between group differences in terms of educational level (p = 0·001) and English fluency (p = 0·001). Lower educational level, though not English language fluency, was associated with poorer appreciation of gestational diabetes as a serious condition and also with a lower valuing of tight glucose control. This effect was seen irrespective of ethnic group. Indian and Vietnamese women indicated a lower valuing of patient autonomy and also reported less negative psychological effects than Caucasian and Filipino women. Women from non-Caucasian ethnicities may be at risk of poorer self-management of gestational diabetes related to lower education, lower health literacy and a lower appreciation of gestational diabetes as a serious condition. Nurses and midwives provide information and advice to women with gestational diabetes. Knowledge about factors that impact on attitude towards gestational diabetes among multiethnic populations is important for developing educational programmes to address their needs. © 2010 Blackwell Publishing Ltd.

2015-01-01

Gestational diabetes mellitus (GDM) is characterised by maternal glucose intolerance and insulin resistance during pregnancy. Myostatin, initially identified as a negative regulator of muscle development may also function in the regulation of placental development and glucose uptake. Myostatin expression in placentae of GDM complicated pregnancies is unknown. However, higher myostatin levels occur in placentae of pregnancies complicated with preeclampsia. We hypothesise that myostatin will be differentially expressed in GDM complicated pregnancies. Myostatin concentrations (ELISA) were evaluated in plasma of presymptomatic women who later developed GDM and compared to plasma of normal glucose tolerant (NGT) women. Furthermore, myostatin protein expression (Western blot) was studied in placentae of pregnant women with GDM (treated with diet or insulin) compared to placentae of NGT women. No significant difference in myostatin concentration was seen in plasma of pre-symptomatic GDM women compared to NGT women. In placenta significant differences in myostatin protein expressions (higher precursor; p myostatin dimer expression (p Myostatin expression in placental tissue is altered under stress conditions (e.g. obesity and abnormal glucose metabolism) found in pregnancies complicated with GDM. We hypothesise that myostatin is active in these placentae and could affect glucose homoeostasis and/or cytokine production thereby altering the function of the placenta.

Gestational diabetes mellitus (GDM) is a metabolic disease diagnosed in 1.7% up to 11.6% pregnancies. The prevalence of adverse pregnancy outcome is significantly higher in the case of early onset of diabetes mellitus. Adropin is a hormone promoting carbohydrate oxidation over fat oxidation, and influence nitric oxide synthase. Copeptin is a cleavage product of the vasopressin precursor recently correlated with diabetes mellitus. The aim of the study was to determine maternal serum adropin and copeptin concentrations in women with early and late manifestation of GDM and to discuss their potential role as biochemical markers of insulin resistance. Case-control study on 58 pregnant Caucasian women. Serum levels of adropin and copeptin were assessed in patients with early onset (GDM1) and classical gestational diabetes mellitus (GDM2). Complications such as macrosomia and hypotrophy were evaluated. There was no significant difference between the study and the control group (age, BMI, parity). Fetal growth disturbance rate was 37.5% in GDM1, 11% in GDM2 and 6% in controls. Adropin concentration in GDM patients was significantly higher than in control group (p gestational diabetes mellitus.

To evaluate glycemic control and pregnancy outcomes among pregnant women with severe insulin resistance treated with 500 units/mL concentrated insulin. Retrospective analysis of gravid women with severe insulin resistance (need for greater than 100 units of insulin per injection or greater than 200 units/d) treated with either 500 units/mL concentrated insulin or conventional insulin therapy. We performed a two-part analysis: 1) between gravid women treated with and without 500 units/mL concentrated insulin; and 2) among gravid women treated with 500 units/mL concentrated insulin, comparing glycemic control before and after its initiation. Seventy-three pregnant women with severe insulin resistance were treated with 500 units/mL concentrated insulin and 78 with conventional insulin regimens. Patients treated with 500 units/mL concentrated insulin were older and more likely to have type 2 diabetes mellitus. Average body mass index was comparable between both groups (38.6 compared with 40.4, P=.11) as were obstetric and perinatal outcomes and glycemic control during the last week of gestation. Within the 500 units/mL concentrated insulin cohort, after initiation of this medication, fasting and postprandial blood glucose concentrations improved. However, the rates of blood glucose values less than 60 mg/dL and less than 50 mg/dL were higher in the 500 units/mL concentrated insulin group after initiation than before, 4.8% compared with 2.0% (Pinsulin in severely obese insulin-resistant pregnant women confers similar glycemic control compared with traditional insulin regimens but may increase the risk of hypoglycemia.

Certain phthalates and bisphenol A (BPA) have been associated with insulin resistance and type 2 diabetes in non-pregnant adults, but studies of gestational diabetes mellitus (GDM) have reported conflicting results for phthalates and no associations with BPA. Our aim was to investigate...... levels were positively associated with 120-min plasma glucose (adjusted β 0.268 and 0.183, p = 0.0002 and 0.010, respectively) in mid-pregnancy. No other monotonic associations were detected between phthalate or phenol levels and fasting or stimulated plasma glucose, β-cell function, insulin resistance......, or 60-min disposition index. Our results support a glycaemia-raising effect of phthalates during pregnancy, consistent with findings in non-pregnant populations and suggest a possible protective effect of exposure to TCS against GDM....

Gupta, Deepali; Kurhe, Yeshwant; Radhakrishnan, Mahesh

2014-04-22

Diabetes is a persistent metabolic disorder, which often leads to depression as a result of the impaired neurotransmitter function. Insulin is believed to have antidepressant effects in depression associated with diabetes; however, the mechanism underlying the postulated effect is poorly understood. In the present study, it is hypothesized that insulin mediates an antidepressant effect in streptozotocin (STZ) induced diabetes in mice through modulation of the serotonin system in the brain. Therefore, the current study investigated the antidepressant effect of insulin in STZ induced diabetes in mice and insulin mediated modulation in the brain serotonin system. In addition, the possible pathways that lead to altered serotonin levels as a result of insulin administration were examined. Experimentally, Swiss albino mice of either sex were rendered diabetic by a single intraperitoneal (i.p.) injection of STZ. After one week, diabetic mice received a single dose of either insulin or saline or escitalopram for 14days. Thereafter, behavioral studies were conducted to test the behavioral despair effects using forced swim test (FST) and tail suspension test (TST), followed by biochemical estimations of serotonin concentrations and monoamine oxidase (MAO) activity in the whole brain content. The results demonstrated that, STZ treated diabetic mice exhibited an increased duration of immobility in FST and TST as compared to non-diabetic mice, while insulin treatment significantly reversed the effect. Biochemical assays revealed that administration of insulin attenuated STZ treated diabetes induced neurochemical alterations as indicated by elevated serotonin levels and decreased MAO-A and MAO-B activities in the brain. Collectively, the data indicate that insulin exhibits antidepressant effects in depression associated with STZ induced diabetes in mice through the elevation of the brain serotonin levels.

Insulin resistance and endogenous hyperinsulinemia are associated with blood hypertension. The aim of this analysis is to estimate the prevalence of blood hypertension one year after insulin treatment in type 2 diabetic patients. and methods: This is a retrospective clinical study of 178 type 2 diabetic patients (57 men and 121 women) insulin treated since at least one year. Mean age is 62 +/- 10 years and mean duration of diabetes is ten years. All patients had a clinical and biological control before treatment with insulin and at least three controls during the first year of insulin treatment (anthropometric measurements, blood pressure, fasting plasma glucose, HbA1C). WHO definition of hypertension is used (blood pressure >or=140 / 90 mmHg). At baseline, 48% of patients have hypertension. After insulin treatment, the prevalence of hypertension significantly increase to 53% (94 / 178) three months later (p=0.008), to 54.5% (98 / 178) six months later (p=0.001) and to 55.6% (99 / 178) twelve months later. This increase in hypertension frequency is associated with a significant weight gain and a better blood glucose control. Insulin therapy may contribute to the development of blood hypertension. It promotes renal sodium retention and increases sympathetic nervous system activity. In the UKPDS intensive blood glucose control with insulin is not associated with an increase of macro vascular complications. These observational data suggest the need for further study of the relationship between exogenous insulin and hypertension.

Recommendations in Switzerland on screening for gestational diabetes endorse the International Association of Diabetes in Pregnancy Study Group consensus. As universal testing is time consuming and glucose loading is unpleasant, the recommendations include a simplification, not performing the glucose loading in women with fasting glycaemia fasting glycaemia was fasting glycaemia. The prevalence of gestational diabetes was 10.9% in our population. Among 251 women with gestational diabetes, fasting glycaemia was ≥5.1 mmol/l in 119 women (47.4%), between 4.4 and fasting glycaemia between 4.4 and fasting glycaemia is an attractive alternative to universal screening with the complete 75-g glucose tolerance test. This strategy is, however, slightly less sensitive than previously reported in higher-risk populations. Fasting glycaemia can be considered as an alternative to the complete test for gestational diabetes screening. © 2016 Royal College of Obstetricians and Gynaecologists.

We aimed to assess the use of metformin (MTF) in the prevention of gestational diabetes mellitus (GDM) in patients with pregestational insulin resistance (PIR). A double blind, multicenter, randomized trial was carried out in patients with a history of PIR and pregestational MTF treatment. Groups were allocated either to MTF 1700 mg/day or placebo. Patients were recruited between 12 +0 and 15 +6  gestational weeks, and treatment was extended until week 36. A multiple logistic regression analysis was applied to determine the relation between the use of metformin and the development of GDM. One hundred and forty one patients were randomized (68 patients in the MTF group and 73 in the placebo group). A total of 30 patients withdrew from the study during follow-up. Administration of MTF was not associated with a decrease in the incidence of GDM as compared to placebo (37.5% vs 25.4%, respectively; P = 0.2). Moreover, MTF administration was associated with a significant increase in drug intolerance as compared to placebo (14.3% vs 1.8%, respectively; P = 0.02). The use of MTF is not effective in prevention of GDM in populations with PIR. The use of MTF shows a significantly higher frequency of drug intolerance than placebo. © 2017 Japan Society of Obstetrics and Gynecology.

Gestational diabetes insipidus is a rare, transient complication of pregnancy typically characterized by polyuria and polydipsia that may lead to mild electrolyte abnormalities. More severe sequelae of gestational diabetes insipidus are uncommon. We present a case of a 25-year-old woman at 23 weeks of gestation in a dichorionic-diamniotic twin pregnancy who developed severe symptomatic gestational diabetes insipidus complicated by rhabdomyolysis and death of both fetuses. Maternal rhabdomyolysis caused by gestational diabetes insipidus is extremely rare. Early recognition and treatment of gestational diabetes insipidus is necessary to prevent maternal and fetal morbidity and mortality.

Renalase is considered as a novel candidate gene for type 2 diabetes. In this study, we aimed to investigate the relationship of serum renalase and two single nucleotide polymorphisms with gestational diabetes mellitus. One hundred and ninety-eight normotensive pregnant females (n = 99 gestational diabetes mellitus; n = 99 euglycemic pregnant controls) were classified according to the International Association of the Diabetes and Pregnancy Study criteria. Fasting and 2-h post glucose load blood levels and anthropometric assessment was performed. Serum renalase was measured using enzyme-linked immunosorbent assay, whereas DNA samples were genotyped for renalase single nucleotide polymorphisms rs2576178 and rs10887800 using Polymerase chain reaction-Restriction fragment length polymorphism method. In an age-matched case control study, no difference was observed in the serum levels of renalase (p > 0.05). The variant rs10887800 showed an association with gestational diabetes mellitus and remained significant after multiple adjustments (p gestational diabetes. Although gestational diabetes mellitus is self-reversible, yet presence of this minor G allele might predispose to metabolic syndrome phenotypes in near the future.

Full Text Available BACKGROUND: Fibroblast growth factor 19 (FGF19 and FGF21 are considered to be novel adipokines that improve glucose tolerance and insulin sensitivity. In the current study, we investigated serum FGF19 and FGF21 levels in patients with gestational diabetes mellitus (GDM and explored their relationships with anthropometric and endocrine parameters. METHOD: Serum FGF19 and FGF21 levels were determined by enzyme-linked immunosorbent assay (ELISA in patients with GDM (n = 30 and healthy pregnant controls (n = 60 matched for maternal and gestational age. Serum FGF19 and FGF21 levels were correlated with anthropometric, metabolic, and endocrine parameters. RESULTS: Circulating levels of FGF19 were significantly reduced in patients with GDM relative to healthy pregnant subjects, whereas FGF21 levels were increased in GDM patients. Serum FGF19 levels independently and inversely correlated with insulin resistance (increased homeostasis model assessment of insulin resistance, HOMA-IR and were positively related to serum adiponectin in both groups. In contrast, serum FGF21 levels independently and positively correlated with insulin resistance and serum triglycerides and were inversely related to serum adiponectin. In addition, in the combined population of both groups, those women with preconception polycystic ovary syndrome (PCOS history had the lowest levels of FGF19, which were significantly lower than those in GDM patients without PCOS history and those in controls without PCOS history. CONCLUSIONS: Circulating FGF19 levels are reduced in GDM patients, in contrast with FGF21 levels. Both serum FGF19 and FGF21 levels are strongly related to insulin resistance and serum levels of adiponectin. Considering the different situation between FGF19 and FGF21, we suggest that reduced serum FGF19 levels could be involved in the pathophysiology of GDM, while increased serum FGF21 levels could be in a compensatory response to this disease.

Full Text Available Maintenance of gestation implicates complex function of multiple endocrine mechanisms, and disruptions of the global metabolic environment prompt profound consequences on fetomaternal well-being during pregnancy and postpartum. Polycystic Ovary Syndrome (PCOS and gestational diabetes mellitus (GDM are very frequent conditions which increase risk for pregnancy complications, including early pregnancy loss, pregnancy-induced hypertensive disorders, and preterm labor, among many others. Insulin resistance (IR plays a pivotal role in the pathogenesis of both PCOS and GDM, representing an important therapeutic target, with metformin being the most widely prescribed insulin-sensitizing antidiabetic drug. Although traditional views neglect use of oral antidiabetic agents during pregnancy, increasing evidence of safety during gestation has led to metformin now being recognized as a valuable tool in prevention of IR-related pregnancy complications and management of GDM. Metformin has been demonstrated to reduce rates of early pregnancy loss and onset of GDM in women with PCOS, and it appears to offer better metabolic control than insulin and other oral antidiabetic drugs during pregnancy. This review aims to summarize key aspects of current evidence concerning molecular and epidemiological knowledge on metformin use during pregnancy in the setting of PCOS and GDM.

We investigated whether a reduced incretin effect, as observed in patients with type 2 diabetes, can be detected in high-risk individuals, such as women with prior gestational diabetes mellitus (pGDM). In this cross-sectional study, 102 women without diabetes with pGDM and 15 control participants without pGDM and with normal glucose tolerance (NGT) underwent a 4 h 75 g OGTT and an isoglycaemic i.v. glucose infusion (IIGI). Women with pGDM were classified as having NGT or prediabetes (impaired fasting glucose and/or impaired glucose tolerance). Insulin sensitivity was assessed using the Matsuda index and HOMA2-IR and the incretin effect was calculated from insulin responses during the study (100% × [AUC insulin,OGTT  - AUC insulin,IIGI ]/AUC insulin,OGTT ). Sixty-three of the 102 women with pGDM (62%) had prediabetes (median [interquartile range]: age, 38.3 [6.5] years; BMI, 32.1 [5.8] kg/m 2 ) and 39 women (38%) had NGT (age, 39.5 [5.6] years; BMI, 31.0 [6.7] kg/m 2 ). Control participants (n = 15) were not significantly different from the pGDM group with regards to age (39.2 [7.4] years) and BMI (28.8 [9.2] kg/m 2 ). Compared with women with NGT and control participants, women with prediabetes had lower insulin sensitivity, as measured by the Matsuda index (3.0 [2.4] vs 5.0 [2.6] vs 1.5 [1.8], respectively; p diabetes. clinicaltrialsregister.eu 2012-001371-37-DK.

Gestational diabetes (GDM) is defined as glucose intolerance first diagnosed with a 75 gram oral glucose tolerance test based on IADPSG criteria which had been recently adopted by WHO. In industrial countries GDM is one of the most frequent pregnancy complications. In 2012, in Germany GDM had been diagnosed in 4,3 % of all births, overall 27,700 cases. GDM has to be considered as a preliminary stage of type 2 diabetes with insulin resistance and inadequate β-cell-compensation. Additionally, adverse metabolic profile, associations with inflammatory parameters, with D vitamin metabolism, and insufficient decline of renal threshold for glucose had been identified in women with GDM. Within 10 years after GDM roughly 50 % of the women convert to overt diabetes, mostly type 2. GDM and type 2 diabetes share potential candidate genes. In about 1 % of GDM in Caucasian women a mutation in glucokinase gene had been found (GCK-MODY). Predisposition to GDM is predominantly characterized by family history of diabetes, previous GDM in pregnancies, factors of metabolic syndrome, and unfavorable life style. The probability for GDM rises with increasing mother's age and preconceptional BMI. Via fetal programming GDM dispones to offspring obesity as early as school entry. Prevention of GDM focus on regular physical exercise, normalizing body weight before conception, reducing excess intake of animal protein and soft drinks, planning of pregnancy in younger ages, and avoiding pollutant exposition as well as smoking cessation. © Georg Thieme Verlag KG Stuttgart · New York.

Sorbitol accumulation is postulated to play a role in skeletal muscle dysfunction associated with diabetes. The purpose of this study was to determine the effects of insulin and of endurance exercise on skeletal muscle sorbitol levels in streptozotocin-induced diabetic rats. Rats were assigned to one experimental group (control sedentary, control exercise, diabetic sedentary, diabetic exercise, diabetic sedentary no-insulin). Diabetic rats received daily subcutaneous insulin. The exercise-trained rats ran on a treadmill (1 hour, 5X/wk, for 12 weeks). Skeletal muscle sorbitol levels were the highest in the diabetic sedentary no-insulin group. Diabetic sedentary rats receiving insulin had similar sorbitol levels to control sedentary rats. Endurance exercise did not significantly affect sorbitol levels. These results indicate that insulin treatment lowers sorbitol in skeletal muscle; therefore sorbitol accumulation is probably not related to muscle dysfunction in insulin-treated diabetic individuals. Endurance exercise did not influence intramuscular sorbitol values as strongly as insulin. PMID:20016800

To evaluate the effect of leptin administration on some biochemical parameters of bone turnover in diabetic rats using either leptin alone or a combination of leptin and insulin. The study was carried out on 32 female Wistar rats supplied by Medical College animal house at King Khalid Hospital, Kingdom of Saudi Arabia during the period from March to December 2006. Rats were divided into 4 groups (8 rats each), controls, non-treated diabetic, leptin-treated diabetic and leptin plus insulin-treated diabetic rats. After induction of diabetes by 6 weeks, treatment with leptin either alone or combined with insulin was continued for 2 weeks more. At the end of treatment, serum samples were taken to measure levels of bone alkaline phosphate (BAP), alkaline phosphates, osteocalcin, insulin like growth factor-1 (IGF-1), parathyroid hormone (PTH), glucose, creatinine, calcium, calcium ions (Ca2+), and phosphorous using enzyme-linked immunoassay (ELISA) and spectrophotometric methods. Body weight and urinary calcium excretion were also measured. Combined leptin and insulin treatment produced a significant increase of serum BAP and a decrease of urinary calcium and serum glucose as compared to rats treated by leptin only, and a significant increase of BAP, alkaline phosphates, IGF-1, and glucose and a decrease in osteocalcin as compared to control rats. Positive correlations were detected between serum IGF-1 levels and each of BAP, alkaline phosphatase and osteocalcin in diabetic rats treated by leptin, and those with leptin plus insulin. Combined leptin plus insulin treatment can offer extra gain of bone formation over leptin treatment alone. Confirmation of these preliminary observations must await careful long-term studies of bone turnover experimental diabetes. (author)

Improvement of glycaemic control and elevation of C-peptide following a diet free of dairy products in an insulin-treated, patient with type 2 diabetes with ulcerative colitis.

Tandeter, Howard

2009-01-01

An insulin-treated patient with type 2 diabetes mellitus started a diet free of dairy products. Unexpectedly, she developed episodes of hypoglycaemia, without any change in her usual medication (insulin NPH at bedtime and Metformin). Laboratory tests showed an improvement of endogenous insulin secretion as demonstrated by the induction of hypoglycaemia and the elevation to normalisation of C-peptide levels. The patient was rechallenged with dairy products, leading to the lowering of the C-peptide levels back to abnormal levels, and an increase in HBA1C levels. The findings in our patient contrast with the insulinotropic effect of milk in healthy subjects described in the literature. The two main "milk debates" on the relation between milk (or its components) and diabetes are presented. Further observations will be needed to clarify the question of whether a diet free of dairy products can improve glycaemic control in other insulin-treated patients with type 2 diabetes.

Little is known about the impact of sleep duration and late-night snacking on glycemic control in patients with type 1 diabetes using insulin pumps. The aim of the present study was to examine whether late-night eating habits and short sleep duration are associated with glycemic control in continuous subcutaneous insulin infusion-treated type 1 diabetic patients. We included 148 consecutive adult type 1 diabetic subjects using an insulin pump (100 women and 48 men). Participants completed a questionnaire regarding sleep duration (classified as short if ≤6 h) and late-night snacking. Other sources of information included medical records and data from blood glucose meters. Glycemic control was assessed by glycated hemoglobin (HbA1c) levels and mean self-monitoring of blood glucose (SMBG) readings. The mean age of patients was 26 years, mean type 1 diabetes duration was 13.4 years and mean HbA1c level was 7.2%. In a univariate regression analysis, sleep duration was a predictor of both HbA1c (β = 0.51, P = 0.01) and SMBG levels (β = 11.4, P = 0.02). Additionally, an association was found between frequent late-night snacking and higher SMBG readings (often snacking β = 18.1, P = 0.05), but not with increased HbA1c levels. In the multivariate linear regression, independent predictors for HbA1c and SMBG were sleep duration and patient age. In a univariate logistic regression, sleep duration and frequency of late-night snacking were not predictors of whether HbA1c target levels were achieved. Short sleep duration, but not late-night snacking, seems to be associated with poorer glycemic control in type 1 diabetic patients treated with continuous subcutaneous insulin infusion.

The benefit of Self-monitoring of Blood Glucose (SMBG) in people with non-insulin treated type 2 diabetes remains unclear with inconsistent evidence from randomised controlled trials fuelling the continued debate. Lack of a consistent finding has been attributed to variations in study population and design, including the SMBG intervention. There is a growing consensus that structured SMBG, whereby the person with diabetes and health care provider are educated to detect patterns of glycaemic abnormality and take appropriate action according to the blood glucose profiles, can prove beneficial in terms of lowering HbA1c and improving overall well-being. Despite this, many national health agencies continue to issue guidelines restricting the use of SMBG in non-insulin treated type 2 diabetes. The SMBG Study is a 12 month, multi-centre, randomised controlled trial in people with type 2 diabetes not on insulin therapy who have poor glycaemic control (HbA1c ≥58 mmol/mol / 7.5%). The participants will be randomised into three comparative groups: Group 1 will act as a control group and receive their usual diabetes care; Group 2 will undertake structured SMBG with clinical review every 3 months; Group 3 will undertake structured SMBG with additional monthly telecare support from a trained study nurse. A total of 450 participants will be recruited from 16 primary and secondary care sites across Wales and England. The primary outcome measure will be HbA1c at 12 months with secondary measures to include weight, BMI, total cholesterol and HbA1c levels at 3, 6, 9 and 12 months. Participant well-being and attitude towards SMBG will be monitored throughout the course of the study. Recruitment began in December 2012 with the last participant visit due in September 2016. This study will attempt to answer the question of whether structured SMBG provides any benefits to people with poorly controlled type 2 diabetes who are not being treated with insulin. The data will also

The treatment of type 1 diabetes mellitus consists of external replacement of the functions of β cells in an attempt to achieve blood levels of glucose as close to the normal range as possible. This approach means that glucose sensing needs to be replaced and levels of insulin need to mimic physiological insulin-action profiles, including basal coverage and changes around meals. Training and educating patients are crucial for the achievement of good glycaemic control, but having insulin preparations with action profiles that provide stable basal insulin coverage and appropriate mealtime insulin peaks helps people with type 1 diabetes mellitus to live active lives without sacrificing tight glycaemic control. Insulin analogues enable patients to achieve this goal, as some have fast action profiles, and some have very slow action profiles, which gives people with type 1 diabetes mellitus the tools to achieve dynamic insulin-action profiles that enable tight glycaemic control with a risk of hypoglycaemia that is lower than that with human short-acting and long-acting insulins. This Review discusses the established and novel insulin analogues that are used to treat patients with type 1 diabetes mellitus and provides insights into the future development of insulin analogues.

Full Text Available Background: Diabetes mellitus is one of the most important diseases in all over the world. Insulin and its receptor are found in specific area of CNS with a variety of regions-specific functions different from its role in direct glucose regulation in the periphery. The hippocampus and cerebral cortex distributed insulin and insulin receptor has been shown to be involved in brain cognitive functions. Previous studies about the effect of insulin on memory in diabetes are controversial and further investigation is necessary.Methods: Seventy male NMRI rats (250-300 g were randomly divided into control, diabetic, saline-saline, saline-insulin (12, 18 or 24 mU, diabetic-saline, diabetic-insulin (12, 18 or 24 mU groups. Diabetes was induced by streptozotocin (65 mg/kg, ip. Saline or insulin were injected bilaterally (1 µl/rat into CA1 region of hippocampus during 1 min. Thirty minutes later, water maze training was performed.Results: Insulin had a dose dependent effect. The spatial learning and memory were impaired with diabetes, and improved by insulin. Escape latency and swimming distance in a water maze in insulin treated animals were significantly lower (P<0.05 than control and diabetic groups. Percentage of time spent by animals in a target quarter in probe trial session showed a significant difference among groups. This difference was significant between insulin treated and the other groups (P<0.05.Conclusions: Our findings suggest that injection of insulin into hippocampal CA1 area may have a dose-dependent effect on spatial learning and memory in diabetic rats.

Aims To test whether the TCF7L2 gene was associated with gestational diabetes, whether the association between TCF7L2 and gestational diabetes was independent of HLA-DQB1*0602 and islet cell autoantibodies, as well as maternal age, number of pregnancies, family history of diabetes and the HLA-DQB1 genotypes, and to test whether the distribution of HLA-DQB1 alleles was affected by country of birth. Methods We genotyped the rs7903146, rs12255372 and rs7901695 single nucleotide polymorphisms of the TCF7L2 gene in 826 mothers with gestational diabetes and in 1185 healthy control subjects in the Diabetes Prediction in Skåne Study. The mothers were also typed for HLA-DQB1 genotypes and tested for islet cell autoantibodies against GAD65, insulinoma-associated antigen-2 and insulin. Results The heterozygous genotypes CT, GT and TC of the rs7903146 (T is risk for Type 2 diabetes), rs12255372 (T is risk for Type 2 diabetes) and rs7901695 (C is risk for Type 2 diabetes), respectively, as well as the homozygous genotypes TT, TT and CC of the rs7903146, rs12255372 and rs7901695, respectively, were strongly associated with gestational diabetes (P gestational diabetes in mothers born in Sweden (P = 0.010). Conclusions The TCF7L2 was associated with susceptibility for gestational diabetes independently of the presence of HLA-DQB1*0602 and islet cell autoantibodies and other factors such as maternal age, number of pregnancies, family history of diabetes and other HLA-DQ genotypes. The HLA-DQB1*0602 was negatively associated with gestational diabetes in mothers born in Sweden. PMID:21672010

Diabetic complications such as cardiovascular disease and osteoarthritis (OA) are among the common public health problems. The effect of insulin on OA secondary to diabetes has not been investigated before in animal models. Therefore, we sought to determine whether insulin and the insulin-mimicking agent, vanadium can protect from developing OA in diabetic rats. Type 1 diabetes mellitus (T1DM) was induced in Sprague-Dawley rats and treated with insulin and/or vanadium. Tissues harvested from the articular cartilage of the knee joint were examined by scanning electron microscopy, and blood samples were assayed for oxidative stress and inflammatory biomarkers. Eight weeks following the induction of diabetes, a profound damage to the knee joint compared to the control non-diabetic group was observed. Treatment of diabetic rats with insulin and/or vanadium differentially protected from diabetes-induced cartilage damage and deteriorated fibrils of collagen fibers. The relative biological potencies were insulin + vanadium > insulin > vanadium. Furthermore, there was about 2- to 5-fold increase in TNF-α (from 31.02 ± 1.92 to 60.5 ± 1.18 pg/ml, p 1) and IL-6 (from 64.67 ± 8.16 to 338.0 ± 38.9 pg/ml, p 1) cytokines and free radicals measured as TBARS (from 3.21 ± 0.37 to 11.48 ± 1.5 µM, p 1) in the diabetic group, which was significantly reduced with insulin and or vanadium. Meanwhile, SOD decreased (from 17.79 ± 8.9 to 8.250.29, p 1) and was increased with insulin and vanadium. The relative potencies of the treating agents on inflammatory and oxidative stress biomarkers were insulin + vanadium > insulin > vanadium. The present study demonstrates that co-administration of insulin and vanadium to T1DM rats protect against diabetes-induced OA possibly by lowering biomarkers of inflammation and oxidative stress.

Aim Exposing a fetus to hyperglycemia can increase the risk for later-life metabolic disorders. Betatrophin has been proposed as a key regulator of pancreatic beta cell proliferation and lipid regulation. Highly responsive to nutritional signals, serum betatrophin concentrations have been found to be altered by various physiological and pathological conditions. We hypothesized that betatrophin levels are increased in the cord blood in offspring exposed to intrauterine hyperglycemia. Methods This was a cross-sectional study including 54 mothers who underwent uncomplicated Cesarean delivery in a university hospital. Maternal gestational glucose concentration was determined at 24–48 weeks gestation after a 75-g OGTT. Cord blood and placental tissue was collected immediately post delivery. Metabolic parameters were determined in the Clinical Laboratory. Cord blood betatrophin levels were assayed using a commercially available ELISA kit. Placental mitochondrial content was determined by real-time PCR. Results Cord blood betatrophin levels were increased in the gestational diabetes mellitus (GDM) group compared with the normoglycemic group. Furthermore, betatrophin levels were positively correlated with maternal gestational 2h post-OGTT glucose, cord blood insulin, HOMA-IR, and inversely correlated with placental mitochondrial content. Conclusions Cord blood betatrophin may function as a potential biomarker of maternal intrauterine hyperglycemia and fetal insulin resistance, which may presage for long-term metabolic impact of GDM on offspring.

Our purpose was to determine whether a history of irregular menses predicts gestational diabetes mellitus independently of traditional risk factors. We analyzed demographic characteristics, body mass index, and menstrual history of 85 pregnant women with gestational diabetes mellitus and compared them with 85 systematically selected control subjects who were matched for age, race, and delivery year. Subjects with pregestational diabetes mellitus, previous gestational diabetes mellitus, family history of diabetes mellitus, weight >200 pounds, previous macrosomic infants, or previous stillbirth were excluded. Demographic characteristics between case and control groups were similar. Mean body mass index was higher among cases (26.5 kg/m(2)) versus control subjects (24.5 kg/m(2), P =.004). Irregular cycles were more prevalent in the cases (24% vs 7%, P =.006). With the use of body mass index as a stratification factor, menstrual irregularity maintained a strong association with gestational diabetes mellitus (P =.014). A history of irregular menstrual cycles was a significant independent predictor of gestational diabetes mellitus. If selective screening is implemented for gestational diabetes mellitus, such history should be considered in the decision of whom to test.

Full Text Available OBJECTIVE: To assess the efficacy and safety of treating pregnant women with gestational diabetes mellitus in comparison to usual antenatal care. METHODS: A systematic review and meta-analysis was conducted by including randomized controlled trials comparing any form of therapeutic intervention in comparison to usual antenatal care. A literature search was conducted using electronic databases together with a hand search of relevant journals and conference proceedings. RESULTS: Ten studies involving 3,881 patients contributed to meta-analysis. Our results indicated that gestational diabetes mellitus treatment significantly reduced the risk for macrosomia (RR, 0.47; 95% CI, 0.38-0.57, large for gestational age births (RR, 0.55; 95% CI, 0.45-0.67, shoulder dystocia (RR, 0.42; 95% CI, 0.23-0.77 and gestational hypertension (RR, 0.68; 95% CI, 0.53-0.87 without causing any significant increase in the risk for small for gestational age babies. However, no significant difference was observed between the two groups regarding perinatal/neonatal mortality, neonatal hypoglycemia, birth trauma, preterm births, pre-eclampsia, caesarean section and labor induction. CONCLUSION: Treating GDM reduces risk for many important adverse pregnancy outcomes and its association with any harm seems unlikely.

In this study, we aimed to evaluate the postnatal problems of infants of mothers with pregestational and gestational diabetes and the clinical properties of infants who were found to have congenital cardiac disease. We retrospectively examined the records of 337 newborns who were followed up with a diagnosis of infant of diabetic mother between January 2010 and January 2012 in our Neonatology Unit. The demographic data of the diabetic mothers and their babies, the postnatal problems of the babies of diabetic mothers and congenital heart diseases found on transthoracic echocardiography were examined. The patients were classified as group A, B and C in accordance with the recommendations of The American Congress of Obstetricians and Gynecologists (ACOG) according to the type of diabetes. The most common postnatal problems included hyperbilirubinemia, respiratory distress, hypoglycemia and hypocalcemia. The rate of congenital heart disease was found be 17.3% in group A, 50% in group B and 9% in group C. No correlation was found between congenital heart disease and gender, multiple pregnancy, diabetes type, diet treatment, use of oral antidiabetic drugs and drug usage. A positive significant correlation was found between congenital heart disease and genetic disease, murmur, cyanosis and presence of gestational hypertension. It was shown that use of insulin, genetic disease and presence of gestational diabetes increased the risk of congenital heart disease. In our study, the overall incidence of congenital heart disease was found to be 24% in infants of diabetic mothers. It should be kept in mind that it is important to investigate the infants of mothers with pregestational and gestational diabetes in terms of the risk of congenital heart disease.

Despite decades of speculation that inhibiting endogenous insulin degradation might treat type-2 diabetes, and the identification of IDE (insulin-degrading enzyme) as a diabetes susceptibility gene, the relationship between the activity of the zinc metalloprotein IDE and glucose homeostasis remains unclear. Although Ide(-/-) mice have elevated insulin levels, they exhibit impaired, rather than improved, glucose tolerance that may arise from compensatory insulin signalling dysfunction. IDE inhibitors that are active in vivo are therefore needed to elucidate IDE's physiological roles and to determine its potential to serve as a target for the treatment of diabetes. Here we report the discovery of a physiologically active IDE inhibitor identified from a DNA-templated macrocycle library. An X-ray structure of the macrocycle bound to IDE reveals that it engages a binding pocket away from the catalytic site, which explains its remarkable selectivity. Treatment of lean and obese mice with this inhibitor shows that IDE regulates the abundance and signalling of glucagon and amylin, in addition to that of insulin. Under physiological conditions that augment insulin and amylin levels, such as oral glucose administration, acute IDE inhibition leads to substantially improved glucose tolerance and slower gastric emptying. These findings demonstrate the feasibility of modulating IDE activity as a new therapeutic strategy to treat type-2 diabetes and expand our understanding of the roles of IDE in glucose and hormone regulation.

The aim of the present study was to evaluate the cost effectiveness of rapid-acting analog insulin relative to regular human insulin in adults with type 1 diabetes mellitus in Germany. The PRIME Diabetes Model, a patient-level, discrete event simulation model, was used to project long-term clinical and cost outcomes for patients with type 1 diabetes from the perspective of a German healthcare payer. Simulated patients had a mean age of 21.5 years, duration of diabetes of 8.6 years, and baseline glycosylated hemoglobin of 7.39%. Regular human insulin and rapid-acting analog insulin regimens reduced glycosylated hemoglobin by 0.312 and 0.402%, respectively. Compared with human insulin, hypoglycemia rate ratios with rapid-acting analog insulin were 0.51 (non-severe nocturnal) and 0.80 (severe). No differences in non-severe diurnal hypoglycemia were modeled. Discount rates of 3% were applied to future costs and clinical benefits accrued over the 50-year time horizon. In the base-case analysis, rapid-acting analog insulin was associated with an improvement in quality-adjusted life expectancy of 1.01 quality-adjusted life-years per patient (12.54 vs. 11.53 quality-adjusted life-years). Rapid-acting analog insulin was also associated with an increase in direct costs of €4490, resulting in an incremental cost-effectiveness ratio of €4427 per quality-adjusted life-year gained vs. human insulin. Sensitivity analyses showed that the base case was driven predominantly by differences in hypoglycemia; abolishing these differences reduced incremental quality-adjusted life expectancy to 0.07 quality-adjusted life-years, yielding an incremental cost-effectiveness ratio of €74,622 per quality-adjusted life-year gained. Rapid-acting analog insulin is associated with beneficial outcomes in patients with type 1 diabetes and is likely to be considered cost effective in the German setting vs. regular human insulin.

Telomeres undergo shortening with cell division, accelerated by increased oxidative stress. We aimed to demonstrate shortened telomeres in the offspring of mothers who have diabetes as a consequence of exposure to increased oxidative stress during intrauterine development. We examined the level of glycaemia (glucose, HbA1c, fructosamine), oxidative stress (lipid peroxidation) and the levels of antioxidant enzymes (Superoxide dismutase (SOD) and Selenium dependent glutathione peroxidase) and correlate these findings with mean telomere length (TL) in maternal and foetal blood in groups of pregnant women with pre-gestational diabetes (PGD), gestational diabetes (GD) and a euglycaemic control group. Foetal and maternal glucose, maternal HbA1c, and foetal insulin and C-peptide were higher in the PGD group with the GD group being intermediate. Markers of oxidative stress did not vary between groups with the exception of foetal SOD activity that was highest in the GD group. There were no detectable differences in maternal or foetal TL between study groups. An exploratory analysis looking at correlations between glycaemic and oxidative stress parameters and TL revealed a negative correlation between maternal and foetal glucose and TL across the whole study population. This relationship held for the short-term marker of glycaemic control, fructosamine. We were unable to show significant telomere shortening in the offspring of mothers with PGD or GD. Exploratory analysis revealed a relationship between foetal TL and short-term glycaemia particularly in PGD. It is possible that increased telomerase activity can compensate for long-term increased oxidative stress but not for short-term dysglycaemia.

To investigate whether polycystic ovary syndrome further increases postpartum diabetes risk in women with gestational diabetes mellitus and to explore relationships between polycystic ovary syndrome and incident diabetes in women who do not develop gestational diabetes. This retrospective cohort study (Quebec Physician Services Claims; Hospitalization Discharge Databases; Birth and Death registries) included 34 686 women with gestational diabetes during pregnancy (live birth), matched 1:1 to women without gestational diabetes by age group, year of delivery and health region. Diagnostic codes were used to define polycystic ovary syndrome and incident diabetes. Cox regression models were used to examine associations between polycystic ovary syndrome and incident diabetes. Polycystic ovary syndrome was present in 1.5% of women with gestational diabetes and 1.2% of women without gestational diabetes. There were more younger mothers and mothers who were not of white European ancestry among those with polycystic ovary syndrome. Those with polycystic ovary syndrome more often had a comorbidity and a lower proportion had a previous pregnancy. Polycystic ovary syndrome was associated with incident diabetes (hazard ratio 1.52; 95% CI 1.27, 1.82) among women with gestational diabetes. No conclusive associations between polycystic ovary syndrome and diabetes were identified (hazard ratio 0.94; 95% CI 0.39, 2.27) in women without gestational diabetes. In women with gestational diabetes, polycystic ovary syndrome confers additional risk for incident diabetes postpartum. In women without gestational diabetes, an association between PCOS and incident diabetes was not observed. Given the already elevated risk of diabetes in women with a history of gestational diabetes, a history of both polycystic ovary syndrome and gestational diabetes signal a critical need for diabetes surveillance and prevention. © 2017 Diabetes UK.

Adiponectin, Leptin, and Leptin Receptor in Obese Patients with Type 2 Diabetes Treated with Insulin Detemir

Directory of Open Access Journals (Sweden)

Paweł Olczyk

2017-07-01

Full Text Available The aim of the present study is to quantitatively assess the expression of selected regulatory molecules, such as leptin, leptin receptor, and adiponectin in the blood of obese patients with type 2 diabetes both before treatment and after six months of pharmacological therapy with the long-lasting insulin analogue, insulin detemir. A significant decrease in the analysed regulatory molecules, i.e., leptin receptor and adiponectin, was found in blood plasma of the patients with untreated type 2 diabetes. These changes were accompanied by an increase in plasma leptin concentrations. Insulin treatment resulted in the normalization of plasma leptin receptor and adiponectin concentrations. The circulating leptin level did not change following anti-diabetic therapy with insulin detemir. Gender was a significant factor modifying the circulating level of all the analysed regulatory active compounds. Bioinformatic analysis was performed using Matlab with the Signal Processing Toolbox. The conducted discriminant analysis revealed that the leptin receptor, Δw(19, and adiponectin, Δw(21, were the parameters undergoing the most significant quantitative changes during the six-month therapy with insulin detemir. The conducted examinations indicated the contribution of adipocytokines—the biologically-active mediators of systemic metabolism, such as leptin and adiponectin in the pathomechanism of disorders being the basis for obesity which leads to development of insulin resistance, which, in turn, results in the occurrence of type 2 diabetes.

Trace Elements and Vitamin D in Gestational Diabetes

Directory of Open Access Journals (Sweden)

Genova Mariana

2018-03-01

Full Text Available Gestational diabetes mellitus (GDM, one of the most common pregnancy complications, is defined as glucose intolerance with onset or first recognition during pregnancy. Its prevalence varies worldwide in dependence on characteristics of the underlying population and applied diagnostic criteria. The etiology is multifactorial and not sufficiently elucidated. Available evidence suggests that the base of pathogenesis is relatively diminished insulin secretion coupled with pregnancy-induced insulin resistance. Modifiable and non-modifiable risk factors for development have been identified. Trace elements and vitamin D could be contributed to modifiable factors for prediction the risk in a large population. Essential trace elements in pregnancy are necessary to overcome systemic oxidative, metabolic and inflammatory stress. Evidence, still inconclusive, has been accumulated about the relation between higher incidence of vitamin D failure/deficiency during pregnancy and GDM. The lower level of 25-OH vitamin D could be associated with increased risk for anemia development, also including pregnant women. This review intends to provide an overview of the possible link between both vitamin D and trace elements as risk factors for GDM development.

This retrospective cohort study was performed to examine the relationship between maternal hepatitis B virus infection, as indicated by the surface antigen status, with the development of gestational diabetes mellitus in a normal-risk Chinese obstetric population. Maternal demographics, risk factors, and pregnancy outcome of 13,683 singleton pregnancies delivering in 1998-2001 were analysed according to maternal hepatitis B surface antigen status, which was routinely screened. Multiple logistic regression analysis was performed to examine the role of hepatitis B infection in the development of gestational diabetes mellitus. The 1138 women (8.3%) with hepatitis B infection had lower mean weight and body mass index, similar prevalence of chronic medical diseases and smokers, but increased prevalence of gestational diabetes mellitus, which remained significant (odds ratio 1.24, 95% confidence interval 1.01-1.51) after adjustment for confounding variables. However, there was no difference in pregnancy outcome. Our results confirmed the independent association between hepatitis B infection with gestational diabetes mellitus. The magnitude of chronic hepatitis B infection in the developing world and certain ethnic groups could have contributed to the high prevalence of gestational and possibly type 2 diabetes in these populations. Further studies on the long-term implications of our finding are warranted.

To investigate the clinical feature, treatment and prognosis of both the mother and the fetus with gestational diabetes insipidus. A total of 7 cases of gestational diabetes insipidus collected in the First Affiliated Hospital of Wenzhou Medical College, Wenzhou Combination of Traditional Chinese Medicine with Western Medicine Hospital, and Zhejiang Taizhou Hospital from June 1993 to June 2006 were analyzed retrospectively. Seven cases symptoms all characterized by excessive thirst polydipsia and polyuria. The average 24 h urinary output was between 11 L to 13 L and manifested of hypobaricuria. After effective treatment (three cases were treated with 1-deamino-8-D-arginine vasopressin, another three patients were managed with hydrochlorothiazide, and the last one was cured with antisterone), seven patients with gestational diabetes insipidus did not have any severe consequences. Their symptoms of excessive thirst, polyuria, and polydypsia disappeared from 7 days to 3 months after parturition. Urinary volume returned to normal standard of 1000-2000 ml during 24 hours. Specific gravity of urine recovered normally between a range 1.015-1.025 and serum sodium recovered between 135-147 mmol/L. The average duration of illness was 52 days. Eight newborn infants survived. Two of them were sent to neonatal intensive care unit for treatment. One was because of premature delivery caused by antepartum eclampsia, and the other case was one of the twins who had hydronephrosis. The baby of the first case left hospital after 3 weeks' treatment. The latter one's symptom disappeared 2 weeks after delivery. No obvious symptom was discovered among all the babies through follow-up telephone calls 42 days after childbirth. Gestational diabetes insipidus is a rare endocrinopathy complicating pregnancy. This disorder is characterized by excessive thirst, polydypsia, polyuria, hypobaric urine and electrolyte disturbances usually manifesting in the third trimester of pregnancy or puerperium

Full Text Available Background: diabetic ketoacidosis and hyperglycemic hyperosmolar nonketotic state are two of the most serious metabolic emergencies in diabetic patients. Objective: to identify the type of metabolic complications (diabetic ketoacidosis and hyperglycemic hyperosmolar nonketotic state in order to analyze the patients’ outcome considering the plasma pH levels, as well as the mode of insulin administration. Method: a cross-sectional descriptive study was conducted in 52 patients admitted to the intensive care unit of the Enrique Cabrera Hospital from 2000 to 2007. The variables analyzed included: type of diabetes mellitus, type of acute complication, mode of insulin administration, blood gas analysis and outcome. Results: diabetic ketoacidosis occurred in 57.5 % of the type 1 diabetic patients and in the 42.5 % of the type 2 diabetics. None of the type 1 diabetics developed hyperglycemic hyperosmolar nonketotic state and this complication was observed in 23.0 % of the patients with diabetes type 2. Microdosing was the mode of insulin administration that predominated in both ketoacidosis and hyperglycemic state cases. Mortality was higher in the hyperglycemic state (67 % and using microdoses in the insulin therapy. Conclusions: diabetic ketoacidosis was the major complication. Mortality from diabetic ketoacidosis and hyperglycemic hyperosmolar nonketotic state was high and the mode of insulin administration was inadequate in some patients.

To evaluate the prognoses associated with psychosocial deprivation in women with gestational diabetes mellitus (GDM). Observational study considering the 1498 multiethnic women with GDM who gave birth between January 2009 and February 2012. Four largest maternity units in the northeastern suburban area of Paris. The 994 women who completed the Evaluation of Precarity and Inequalities in Health Examination Centers (EPICES) questionnaire. Main complications of GDM (large infant for gestational age (LGA), shoulder dystocia, caesarean section, pre-eclampsia). Psychosocial deprivation (EPICES score ≥30.17) affected 577 women (56%) and was positively associated with overweight/obesity, parity and non-European origin, and negatively associated with family history of diabetes, fruit and vegetable consumption and working status. The psychosocially deprived women were diagnosed with GDM earlier, received insulin treatment during pregnancy more often and were more likely to have LGA infants (15.1% vs 10.6%, OR=1.5 (95% CI 1.02 to 2.2), p<0.05) and shoulder dystocia (3.1% vs 1.2%, OR=2.7 (0.97 to 7.2), p<0.05). In addition to psychosocial deprivation, LGA was associated with greater parity, obesity, history of GDM, ethnicity, excessive gestational weight gain and insulin therapy. A multivariate analysis using these covariates revealed that the EPICES score was independently associated with LGA infants (per 10 units, OR=1.12 (1.03 to 1.20), p<0.01). In our area, psychosocial deprivation is common in women with GDM and is associated with earlier GDM diagnoses and greater insulin treatment, an increased likelihood of shoulder dystocia and, independently of obesity, gestational weight gain and other confounders with LGA infants.

The advantages of continuous subcutaneous insulin infusion (CSII) or insulin glargine have been demonstrated both in adult and paediatric diabetic patients; however, as no data comparing these two approaches during childhood are available, we have examined the efficacy of these two intensive approaches. We retrospectively evaluated data from 36 diabetic children, who had changed their previous insulin regimen [with isophane insulin (NPH) at bedtime] because of HbA1c levels >8.0%. Twenty patients underwent CSII, while the other 16 (significantly younger for age) started insulin glargine at bedtime. At 6 and 12 months, CSII-treated patients showed a significant reduction in HbA1c values from 8.5 +/- 1.8 to 7.4 +/- 1.1% and to 7.6 +/- 1.2%, respectively. The insulin requirement significantly decreased from 0.93 +/- 0.2 IU/kg to 0.73 +/- 0.2 IU/kg of body weight and to 0.74 +/- 0.15 IU/kg of body weight, respectively, while no significant differences were observed for BMI SDS, fructosamine and severe hypoglycaemic events. The patients treated with glargine showed a small decline in HbA1c values from 8.9 +/- 1.7 to 8.3 +/- 0.9% (not significant) in the first 6 months of treatment and to 8.2 +/- 0.9% after 12 months. The basal insulin supplementation can be supplied effectively in children with type 1 diabetes by either CSII or insulin glargine. As previously reported for adults, it is confirmed that CSII is the best current intensive approach aimed to the improvement of glycaemic control.

Full Text Available Nazia Raja-Khan, Sarah S Warehime, Robert A GabbayDivision of Endocrinology, Diabetes, and Metabolism, Penn State Institute for Diabetes and Obesity, Pennsylvania State University College of Medicine, Hershey, Pennsylvania, USABackground: Insulin is an effective treatment for achieving glycemic control and preventing complications in patients with diabetes. In order to make insulin therapy more acceptable to patients, newer formulations of insulin have been developed, such as biphasic insulins. Biphasic insulins conveniently provide both prandial and basal insulin in a single injection. One of the most well-studied biphasic insulins is biphasic insulin aspart 70/30.Objective: Our goal was to review the current literature on the safety and efficacy of biphasic insulin aspart in type 1 and type 2 diabetes.Methods: A MEDLINE search was conducted using the terms “biphasic insulin aspart” to identify clinical studies and reviews.Results: Biphasic insulin aspart more effectively reduces post-prandial glucose compared to other biphasic insulins and basal insulins. Compared to biphasic insulin aspart, fasting glucose levels are lower with NPH, similar with glargine, and similar or lower with biphasic human insulin. Treat-to-target trials have shown that a goal HbA1c below 6.5 or 7% can be achieved with biphasic insulin aspart. The risk of hypoglycemia is similar to or less than that seen with other biphasic insulins or NPH insulin.Conclusion: Biphasic insulin aspart 70/30 is a safe and effective treatment option for patients with diabetes.Keywords: biphasic insulin aspart, insulin, diabetes
