Abnormal Glucose Metabolism

ObjectiveGestational diabetes mellitus (GDM) is a metabolic disorder of pregnancy that is increasingly prevalent among Chinese women. Few studies have examined whether the migration status of Chinese women contributes to the risks of developing GDM during pregnancy.Research design and methodsIn this observational, cross-sectional and hospital-based study, we examined the prevalence of GDM and glycemic levels at oral glucose tolerance test (OGTT) among 491 Australian Chinese migrants (n=491) and native Chinese (n=1000). We defined GDM using the International Association of Diabetes and Pregnancy Study Groups guidelines. We collected data on maternal age, body mass index (BMI) and gestational age (GA) at booking and GA at delivery from medical records. We used multiple logistic and linear regression models to calculate the OR of having GDM and mean differences in glycemic levels in Australian Chinese migrants, relative to native Chinese.ResultsAge-at-booking and BMI-at-booking adjusted GDM prevalence was significantly higher in Australian Chinese migrants than native Chinese (19.7% vs 14.6%; p=0.01). After adjusting for age, BMI at booking and GA at booking, fasting glucose levels were significantly lower (β −0.08 mmol/L; 95% CI −0.14 to 0.02), while 2-hour glucose levels were significantly higher (0.22 mmol/L; 0.02 to 0.43) in Australian Chinese immigrants than native Chinese.ConclusionsMigration status may be a marker for abnormal glucose metabolism during pregnancy among Australian Chinese migrants, possibly due to socio-economic disadvantages and lifestyle changes associated with migration.

Abnormal Glucose Metabolism

A prediabetic state is a major risk factor for the development of diabetes, and, because of an identical pathophysiological background of both conditions, their prevalence increases parallelly and equally fast. Long-term hyperglycemia is the main cause inducing chronic complications of diabetes, yet the range of glucose levels at which they start has not been yet unequivocally determined. The current data show that chronic microvascular complications of diabetes can be observed in patients with abnormal glucose metabolism in whom glycaemia is higher than optimal but below diagnostic criteria for diabetes. Prediabetes is a heterogenous nosological unit in which particular types are differently characterized and show different correlations with particular kinds of complications. Analysis of the latest research results shows the need to continue studies in a larger population and can imply the need to verify the currently employed criteria of diagnosing diabetes and chronic complications of diabetes in people with prediabetes.

<p>Individuals suffering from Type 2 diabetes develop prediabetes before progression of diabetes. In case of prediabetes people, the blood glucose levels are higher than normal but not sufficient to be diagnosed as diabetes. On the basis of existing reports on Sesame extract, SesaVita<sup>TM</sup> which is an herbal food supplement containing Sesame seeds (<em>Sesamum indicum</em> L.) extract may provide an option for management of prediabetes. The objective of this study was to determine the beneficial effects of SesaVita<sup>TM</sup> in prediabetes and mild to moderate hyperlipidemia subjects. This randomized, placebo-controlled, double-blind study comprised of 13 female and 07 male patients with prediabetes and mild to moderate hyperlipidemia, aged between 18 and 65 years. Twenty subjects were randomized to receive SesaVita<sup>TM</sup> (500 mg/day) or placebo along with therapeutic lifestyle changes for 6 weeks. The primary outcome was the measure of efficacy in terms of change in serum lipid profile and glycaemic levels on week 3 and 6. Secondary outcome measures include safety and tolerability evaluated by physical examination and clinical laboratory evaluations. Improvements in lipid profile and glycaemic levels were observed in SesaVita<sup>TM</sup> treated group when compared with placebo and baseline. A statistical significant reduction was observed in low density lipoprotein cholesterol (LDL-C), total cholesterol (TC), oral glucose tolerance test (OGTT) and fasting blood sugar (FBS) levels during week 3 and 6 when treated with SesaVita<sup>TM</sup> extract.<em> </em>No adverse events occurred and all safety parameters were within normal ranges during the study. This study revealed that the treatment with SesaVita<sup>TM</sup> was safe and well tolerated;<em> </em>may be beneficial in the management of prediabetes and mild-to-moderate hyperlipidemia.</p>

Abstract Background: Obesity-induced elevated serum free fatty acids (FFAs) levels result in the occurrence of type 2 diabetes mellitus (T2DM). However, the molecular mechanism remains largely enigmatic. This study was to explore the effect and mechanism of KLF15 on FFAs-induced abnormal glucose metabolism. Methods: Levels of TG, TC, HDL-C, LDL-C, and glucose were measured by different assay kits. qRT-PCR and Western Blot were used to detect the levels of GPR120, GPR40, phosphorylation of p38 MAPK, KLF15, and downstream factors. Results: KLF15 was decreased in visceral adipose tissue of obesity subjects and high-fat diet (HFD) mice. In HFD mice, GPR120 antagonist significantly promoted KLF15 protein expression level and phosphorylation of p38 MAPK, meanwhile reduced the blood glucose levels. While, blocking GPR40 inhibited the KLF15 expression. In 3T3-L1 adipocytes, 1500 μM PA inhibited KLF15 through a GPR120/P-p38 MAPK signal pathway, and 750 μM OA inhibited KLF15 mainly through GPR120 while not dependent on P-p38 MAPK, ultimately resulting in abnormal glucose metabolism. Unfortunately, GPR40 didn’t contribute to PA or OA-induced KLF15 reduction. Conclusions: Both PA and OA inhibit KLF15 expression through GPR120, leading to abnormal glucose metabolism in adipocytes. Notably, the inhibition of KLF15 expression by PA depends on phosphorylation of p38 MAPK.

Aim. To estimate the parameters of glucose metabolism and to assess the secretion of incretins in patients after biliopancreatic diversion (BPD) for morbid obesity (MO) in the early and late postoperative periods. Subjects and methods. The prospective part of the investigation included 22 patients with a body mass index of 35.8 to 68.4 kg/m2 and type 2 diabetes mellitus (T2DM). All the patients were examined before, 3 weeks and 3 months after BPD. The retrospective part covered 23 patients who were examined after BPD for MO; the postoperative period was 4.7 [2.3; 7.2] years. A control group consisted of 22 healthy, normal weight volunteers. A 75-g oral glucose tolerance test was carried out in all the groups to study the levels of glucose, immunoreactive insulin (IRI), glucagon-like peptide-1 (GLP-1), glucose-dependent insulinotropic polypeptide (GIP) and glucagon at 0, 30, 60, and 120 min. Results. T2DM patients showed improvement in glucose metabolism just 3 weeks after BPD; following 3 months, they had normalized fasting blood glucose levels (5.6 [5.0; 6.0] mmol/l). During 3 months, glycated hemoglobin decreased from 7.5 [6.6; 8.5] to 5.7 [5.3; 5.9]%. In the early period following BPD, there was an increase in basal and postprandial GLP-1 levels associated with the peak IRI concentration. In the late period after BPD, the enhanced secretion of IRI and GLP-1 persisted, which was followed by a reduction in postprandial glucose levels in 4 of the 23 patients. Conclusion. T2DM remission does not depend on weight loss in the early period after BPD. In this period, the significant improvement of glucose metabolic parameters in patients with obesity and T2DM is associated with elevated GLP-1 levels. The altered incretin response is a stable effect of BPD and remains in its late period.

Abnormal Glucose Metabolism

Objective: Polycystic ovary syndrome (PCOS) is a risk factor for type 2 diabetes mellitus and screening for abnormal glucose metabolism has been recommended by an oral glucose tolerance test (OGTT). This procedure is time-consuming and inconvenient, limiting its general use. Therefore, an easy method is wanted to separate PCOS women with normal from those with potentially abnormal glucose metabolism. Design: Simple parameters obtained from 101 consecutive PCOS patients were assessed by receiver operating curve analysis for their ability to predict abnormal glucose metabolism. Results: Comparing discriminating parameters at defined sensitivities revealed that, assessed by homeostasis model assessment (HOMA), insulin resistance (HOMA%S) had the highest specificitiy. At a cut-off point of 73.1%, HOMA%S had a sensitivity of 95.5% and a specificity of 51.9%. Applying this cut-off separated 59 women who had a high probability of abnormal glucose metabolism from 42 women who were at low risk (less than 2.5%). Fasting insulin was the second-best parameter and had a similar specificity. A screening strategy which applies HOMA%S or fasting insulin could almost halve the number of OGTTs by directing them to those PCOS women most likely to be suffering from abnormal glucose metabolism. The negative predictive value of this strategy was 97%. The strategy was tested and confirmed in a second and independent cohort of 264 PCOS women. Conclusions: HOMA%S, or to a lesser extent fasting insulin, appears to allow for stratified metabolic screening of PCOS women with OGTT.

Abstract Diabetes mellitus (DM) and abnormal glucose metabolism are associated with cardiovascular (CV) disease. We investigated the prevalence and prognostic importance of dysglycaemia in patients with acute coronary syndromes (ACS) in the PLATelet inhibition and patient Outcomes (PLATO) trial. Diabetes was defined as known diabetes or HbA1c ≥ 6.5% or non-fasting glucose ≥ 11.1 mmol/L on admission, prediabetes as HbA1c ≥ 5.7% but < 6.5%, and no diabetes as HbA1c < 5.7%. The primary endpoint was the composite of CV death, spontaneous myocardial infarction type 1 (sMI) or stroke at 12 months. Multivariable Cox regression models, adjusting for baseline characteristics, and biomarkers NT-proBNP and troponin I, were used to explore the association between glycaemia and outcome. On admission, 16,007 (86.1%) patients had HbA1c and/or glucose levels available and were subdivided into DM 38.5% (6160) (1501 patients had no previous DM diagnosis), prediabetes 38.8% (6210), and no DM 22.7% (3637). Kaplan Meier event rates at 12 months for CV death, sMI or stroke per subgroups were 14.5% (832), 9.0% (522), and 8.5% (293), respectively with multivariable adjusted HRs, versus no diabetes, for diabetes: 1.71 (1.50–1.95) and for prediabetes 1.03 (0.90–1.19). Corresponding event rates for CV death were 6.9% (391), 3.4% (195) and 3.0% (102), respectively, with adjusted HRs for patients with DM of: 1.92 (1.42–2.60) and for prediabetes 1.02 (0.79–1.32). Abnormal glucose metabolism is common in ACS patients, but only patients with definite DM have an increased CV risk, indicating that prediabetes is not immediately associated with worse CV outcomes.

Abstract Objectives The association between plasma irisin and glucose levels in general population was controversial and few researches longitudinally explored this correlation. We aimed to examine whether mid-pregnancy irisin was associated with postpartum glucose among Chinese women and explore the potential modifiable factors. Methods We conducted a prospective cohort study in Guangzhou, China during 2017–2018 and 453 pregnant women (20–28 weeks) were enrolled. At 6–8 weeks after birth, 94 women with gestational diabetes mellitus (GDM) underwent a 75 g oral glucose tolerance test, and the other 359 women had a fasting blood glucose (FBG) test. Multivariable linear regression, quantile regression, and logistic regression analysis were conducted. Results Mean baseline plasma irisin was 13.73 ng/ml. The prevalence of postpartum impaired fasting glucose (IFG) was 14.35% in all participants. Among women with previous GDM, 23 (24.47%) had impaired glucose tolerance (IGT). We found a significantly negative association between mid-pregnancy irisin and postpartum FBG (β: −0.056 ± 0.024). While quantile regression showed the associations were only significant in high percentiles of FBG (P50 to P95), and the magnitude displayed an increasing trend. In addition, higher baseline irisin was associated with lower risk of postpartum IFG (RR, 0.563; CI, 0.384–0.825). Furthermore, we detected significant interactions between irisin and breastfeeding on FBG and IFG (both Pinteraction &lt; 0.05). But baseline irisin was not significantly associated with postpartum postprandial glucose levels or the risk of IGT in women with GDM. Conclusions Plasma irisin levels during mid-pregnancy were negatively associated with FBG and IFG at 6–8 weeks postpartum among Chinese women, and stronger associations in women with higher FBG values were observed. Moreover, breastfeeding may modify this relationship.

Abstract Background:Polycystic ovary syndrome (PCOS) is one of the common endocrine disorders affecting young women and has been associated with an increased risk of impaired glucose tolerance and type 2 diabetes mellitus. However, there are very few studies on glucose abnormalities in Indian adolescent girls with PCOS. This study was conducted to determine the prevalence of abnormal glucose metabolism in this patient population. Method: Study group comprised of 106 young females aged 13–18 years. None of them were on metformin at the time of initial visit. Clinical examination along with Anthropometric evaluation was done and along with routine hormonal assessment they underwent a standard 75-g oral glucose tolerance test (OGTT). American Diabetes Association (ADA) criteria were used for diagnosis of diabetes (2 hr value&gt;200mg/dl), Impaired glucose tolerance (2 hour value &gt; 140 -199 mg/dl) and Impaired fasting glucose (blood glucose level of 100–125 mg/dl) Results:Out of 106 girls with PCOS diagnosis;1 girl met criteria for diagnosis of type 2 diabetes mellitus (0.9%).15 had impaired glucose tolerance (14.1%). In addition, 2 girls with impaired glucose tolerance were also noted to have impaired fasting glucose (1.9%).Abnormalities of glucose metabolism had significant correlation with BMI(p-0.02),Waist circumference (p-0.01) and testosterone levels (p-0.02). Conclusions:In our series of adolescent PCOS subjects, we report the prevalence of abnormal glucose metabolism to be 14.1% which is quite significant. Based on our results, we recommend that all adolescent girls with a diagnosis of PCOS should undergo formal oral glucose tolerance testing. Further studies are necessary in this field, so as to make guidelines regarding the timing and frequency of this testing, as well as its utility in the clinical management of these girls.
