Oral glucose tolerance test for diabetes a two-hour, 75-gram oral glucose tolerance test (ogtt) is used to test for diabetes. a healthcare provider will take a fasting lab draw of blood to test. Results of the oral glucose tolerance test are given in milligrams per deciliter (mg/dl) or millimoles per liter (mmol/l). type 2 diabetes. if youre being tested for type 2 diabetes, two hours after drinking the glucose solution: a normal blood glucose level is lower than 140 mg/dl (7.8 mmol/l).. The oral glucose tolerance test (ogtt) was the gold standard for making the diagnosis of type 2 diabetes. it is still commonly used during pregnancy for diagnosing gestational diabetes. with an oral glucose tolerance test, the person fasts overnight (at least 8 hours, but not more than 16 hours)... An advantage of the oral glucose tolerance test or ogtt is that it is usually a more sensitive test than the fasting plasma glucose test and the hemoglobin a1c test. the test can also be adjusted depending on whether ...

Abnormal glucose regulation describes a condition with disturbed glucometabolic status. Patients with this abnormality have an increased risk of developing both micro- and macrovascular complications. Patients with abnormal glucose regulation composite a large percentage of patients undergoing coronary revascularization. These patients have a poorer prognosis following coronary revascularization compared to normoglycaemic patients. Thus, screening for undiagnosed diabetes mellitus is recommended in patients with established coronary artery disease. Currently there are three methods available to identify abnormal glucose regulation; fasting plasma glucose, an oral glucose tolerance test and glycated haemoglobin (HbA1c). The sensitivity of these methods in identifying abnormal glucose regulation in patients with concomitant coronary artery disease is essential. We therefore aimed to validate the diagnostic strength of in-hospital HbA1c in detection of abnormal glucose tolerance in patients ...

Introduction: Impaired glucose tolerance (IGT) as well as diabetes is associated with the development of cardiovascular disease. We tested the hypothesis that central hemodynamic responses to oral glucose loading were different according to the status of glucose tolerance.. Methods: This study enrolled 89 patients with known or suspected coronary artery disease who underwent 75g oral glucose tolerance test (OGTT). Augmentation index (AIx) and central systolic blood pressure (cSBP) were measured using radial applanation tonometry (Omron, HEM 9000-AI) at fasting, and 1, 2 hours after oral glucose loading.. Results: In overall patients, oral glucose loading increased pulse rate (60.0 ± 10.4 to 64.7 ± 11.9 bpm, p,0.001), and decreased AIx normalized to a heart rate of 75 bpm (AIx@75) (81.6 ± 13.9 to 74.5 ± 14.1 %, p,0.001) and cSBP (114.7 ± 22.2 to 108.6 ± 21.3 mmHg, p,0.001) at 2h. OGTT identified normal glucose tolerance (NGT) in 40 patients, IGT in 36 patients and diabetes in 13 patients. ...

BACKGROUND: Very few studies on glucose abnormalities in European overweight/obese children and adolescents are available, and scientific evidence on the value of standard oral glucose tolerance test (OGTT) in childhood is lacking. We therefore aimed to establish prevalence and features of impaired fasting glucose (IFG), impaired glucose tolerance (IGT) and type 2 diabetes (T2D) in a large cohort of Italian overweight/obese children and adolescents and to assess the validity of standard OGTT in the paediatric population. METHODS: This is a 1-year observational study conducted on 736 (535 overweight/obese and 201 normal weight) consecutive paediatric patients attending the outpatient clinic of Paediatric Endocrine Unit. Clinical and biochemical parameters were collected for all participants. All overweight/obese subjects underwent OGTT. RESULTS: We observed a high prevalence of IFG (7.66%), more than twice that observed in other European children, but a low prevalence of IGT (3.18%) and T2D ...

The glucose tolerance test is a medical test in which glucose is given and blood samples taken afterward to determine how quickly it is cleared from the blood. The test is usually used to test for diabetes, insulin resistance, impaired beta cell function, and sometimes reactive hypoglycemia and acromegaly, or rarer disorders of carbohydrate metabolism. In the most commonly performed version of the test, an oral glucose tolerance test (OGTT), a standard dose of glucose is ingested by mouth and blood levels are checked two hours later. Many variations of the GTT have been devised over the years for various purposes, with different standard doses of glucose, different routes of administration, different intervals and durations of sampling, and various substances measured in addition to blood glucose. The glucose tolerance test was first described in 1923 by Jerome W. Conn. The test was based on the previous work in 1913 by A. T. B. Jacobson in determining that carbohydrate ingestion results in ...

Background Impaired glucose regulation, measured with an oral glucose-tolerance test, has been associated with the risk of cancer. Here, we explored whether the response to an intravenous glucose-tolerance test (IVGTT) is associated with the risk of cancer. Methods A cohort of 945 healthy men, aged 40-59 years in 1972-75, was followed for 40 years. An IVGTT was performed at baseline. Blood samples for glucose determinations were drawn immediately before glucose injection and thereafter every 10 min for 1 h. Associations were assessed with incidence rate ratios (IRR) and Cox models. Findings Cancer incidence was higher among men with 10-min glucose levels below the median than in men with levels above the median (IRR: 1.5, 95% CI: 1.2-1.9). This association remained significant after adjusting for relevant confounders (HR: 1.6, 95% CI: 1.3-2.1) and when excluding the first 10 years of follow-up to minimize the possibility of reverse causality (HR: 1.5, 95% CI: 1.2-2.0). Interpretation Healthy ...

We investigated glucose tolerance and postprandial glucose fluxes immediately after a single bout of aerobic exercise in subjects representing the entire glucose tolerance continuum. Twenty-four men with normal glucose tolerance (NGT), impaired glucose tolerance (IGT), or type 2 diabetes (T2D; age: 56 ± 1 years; body mass index: 27.8 ± 0.7 kg/m(2), P , 0.05) underwent a 180-min oral glucose tolerance test (OGTT) combined with constant intravenous infusion of [6,6-(2)H2]glucose and ingestion of [U-(13)C]glucose, following 1 h of exercise (50% of peak aerobic power) or rest. In both trials, plasma glucose concentrations and kinetics, insulin, C-peptide, and glucagon were measured. Rates (mg kg(-1) min(-1)) of glucose appearance from endogenous (RaEndo) and exogenous (oral glucose; Ra OGTT) sources, and glucose disappearance (Rd) were determined. We found that exercise increased RaEndo, RaOGTT, and Rd (all P , 0.0001) in all groups with a tendency for a greater (~20%) peak RaOGTT value in NGT ...

The most common glucose tolerance test is the oral glucose tolerance test (OGTT). Before the test begins, a sample of blood will be taken. You will then be asked to drink a liquid containing a certain amount of glucose (usually 75 grams). Your blood will be taken again every 30 to 60 minutes after you drink the solution. The test may take up to 3 hours.. A similar test is the intravenous (IV) glucose tolerance test (IGTT). It is rarely used, and is never used to diagnose diabetes. With IGTT, glucose is injected into your vein for 3 minutes. Blood insulin levels are measured before the injection, and again at 1 and 3 minutes after the injection. The timing may vary.. ...

The quantity of deuterated glucose customarily given in labelled IVGTTs (intravenous glucose tolerance tests) changes the isotopic composition of the subjects body water enough to be detected by mass spectrometric techniques. Glucose undergoing direct glycogenesis does not contribute label to the body water pool, and isotope incorporated into it must have come from glucose that has either been oxidized or undergone indirect glycogenesis. By subtracting the amount of label found in body water from the total amount of glucose utilized, as calculated from the minimal model of glucose disappearance, it should be possible to study the partitioning of the dose given between direct glycogenesis in skeletal muscle and other metabolic pathways. To establish these principles, we used isotope ratio MS to determine body water composition in groups of healthy (n=7; mean weight, 76 kg; fasting plasma glucose and insulin, 5.1 mmol and 40 pmol respectively) and Type II diabetic (n=5; mean weight, 84 kg; ...

Background: The diagnosis of diabetes mellitus (DM) is based on either fasting plasma glucose levels or an oral glucose tolerance test (OGTT). Recently, an HbA1c value of ≥48 mmol/mol (6.5%) has been included as an additional test to diagnose DM. The purpose of this study was to validate HbA1c versus OGTT as a method to diagnose DM in vascular surgery patients.. Methods: The study population consisted of 345 patients admitted consecutively due to peripheral arterial disease. Sixty-seven patients were previously diagnosed with DM. Glucose levels of OGTT and HbA1c values were analyzed in 275 patients. The OGTT results were categorized into three groups according to the World Health Organization 1999 criteria: 1) DM defined as fasting plasma glucose (FPG) ≥ 7.0 mmol/L and/or two-hour value (2-h-value) ≥ 11.1 mmol/L; 2) intermediate hyperglycaemia, which consists of IGT (FPG , 7.0 mmol/L and a 2-h-value between 7.8 mmol/L and 11.1 mmol/L), and IFG (fasting glucose value between 6.1 mmol/L and ...

Introduction: Patients with cystic fibrosis (CF) and normal glucose tolerance (NGT) may exhibit diabetic glucose tolerance during pulmonary exacerbations [1].. Aims: We examined glucose tolerance during exacerbations in children with CF and compared continuous glucose monitoring (CGM) with the gold standard oral glucose tolerance test (OGTT).. Methods: Children with CF aged at least 10 years hospitalised with an exacerbation were recruited. Those with diabetes and those on corticosteroids were excluded. On admission, patients had an OGTT and were fitted with a CGM for 3 days. Six weeks post discharge both tests were repeated.. Results: Ten patients (3 males), mean age 13.9 years, have completed the study. Two patients had CGM alone, 4 patients had OGTT alone and 4 patients had both tests. By OGTT criteria, 3 were diabetic, 3 had NGT and 2 had impaired glucose tolerance (IGT) during exacerbations. Glucose tolerance status did not change between exacerbation and follow-up although mean 2-hour ...

AIMS: Children with type 1 diabetes (T1D) risk and islet autoantibodies are recruited to a secondary prevention study. The aims were to determine metabolic control in relation to human leukocyte antigen (HLA) genetic risk and islet autoantibodies in prepubertal children.. METHODS: In 47 healthy children with GADA and at least one additional islet autoantibody, intravenous glucose tolerance test (IvGTT) and oral glucose tolerance test (OGTT) were performed 8-65 d apart. Hemoglobin A1c, plasma glucose as well as serum insulin and C-peptide were determined at fasting and during IvGTT and OGTT.. RESULTS: All children aged median 5.1 (4.0-9.2) yr had autoantibodies to two to six of the beta-cell antigens GAD65, insulin, IA-2, and the three amino acid position 325 variants of the ZnT8 transporter. In total, 20/47 children showed impaired glucose metabolism. Decreased (≤ 30 μU/mL insulin) first-phase insulin response (FPIR) was found in 14/20 children while 11/20 had impaired glucose tolerance in ...

Antiretroviral therapy dramatically reduced HIV-related morbidity and mortality, prolonging the lifespan of HIV-infected patients. Greater duration of infection and exposure to antiretroviral therapy makes these patients susceptible to traditional cardio-metabolic risk factors and pathologies. The optimal diagnostic protocol for Diabetes Mellitus in these patients is still controversial. Haemoglobin A1c (HbA1c) has been shown to underestimate glycaemia levels and the oral glucose tolerance test (OGTT) has been shown to reveal cases of glucose metabolism disturbances in patients with normal fasting glucose. Thus, this study aimed to determine the prevalence of prediabetes and diabetes in a population of HIV-infected patients undergoing combined antiretroviral therapy, using three different diagnostic methods (fasting glucose, OGTT and HbA1c), to determine the agreement between the different methods and the characteristics associated with each one. This study analyzed 220 HIV-infected patients on

Growth hormone (GH) and Insulin-like growth factor-I (IGF-I) secretion are altered in acromegaly and type 2 Diabetes Mellitis (DM). The secretion of GH is mediated by central hypothalamic hormones (GH Releasing Hormone and somatostatin) as well as peripheral factors providing feedback inhibition (IGF-I and glucose, among others). The purpose of this study is to compare growth hormone suppression after an oral glucose tolerance test (OGTT) to growth hormone suppression after recombinant human IGF-I (rhIGF-I) administration. This study will recruit participants with active acromegaly, type 2 diabetes mellitus, and healthy control subjects. Each participant will undergo a screening evaluation, and three subsequent visits. Each participant will receive a placebo subcutaneous injection, OGTT, and administration of rhIGF-I, on separate visit days. Glucose, insulin, GH, bioactive IGF-I and IGF-I binding proteins will be measured after each intervention. Results will be compared between the three ...

Of the 146 CNMs who provided postpartum care and responded to the survey (62.2% response rate), 50.4% reported screening women with GDM-affected pregnancies for abnormal glucose tolerance at the postpartum visit. Of CNMs who screened postpartum, only 48.4% used fasting blood sugar or the 2-hour oral glucose tolerance test. Although 86.2% of all responding CNMs reported that they inform women with recent histories of GDM of their increased risk for type 2 diabetes mellitus, only 63.1% counseled these women to exercise regularly and 23.3% reported referring overweight/obese women to a diet support group or other nutrition counseling. CNMs reported that identification of community resources for lifestyle interventions and additional training in postpartum screening guidelines may help to improve postpartum care ...

OBJECTIVE. The aim of this study was to investigate the effect of catch-up growth occurring at different stages of childhood on glucose levels and β-cell function at 7 years of age.. METHODS. Oral glucose tolerance tests were performed on 152 7-year-old children. Anthropometric data were available from birth to 7 years of age. Children were split into catch-up, catch-down, and normal-growth groups on the basis of growth rates between birth and 1 year, birth and 5 years, and birth and 7 years. Fasting and 30- and 120-minute blood samples collected during the oral glucose tolerance tests were assayed for glucose, insulin, proinsulin, and des-31,32-proinsulin levels, and area-under-the-curve values were calculated.. RESULTS. Children with catch-up growth between birth and 5 years or birth and 7 years had greater area-under-the-curve insulin levels than the children with catch-down growth. Children with catch-up growth only between birth and 7 years exhibited higher proinsulin levels and a greater ...

We examined antepartum clinical characteristics along with measures of glucose tolerance, insulin sensitivity, pancreatic β-cell function, and body composition in Latino women with gestational diabetes mellitus (GDM) for their ability to predict type 2 diabetes or impaired glucose tolerance (IGT) within 6 months after delivery. A total of 122 islet cell antibody-negative women underwent oral and intravenous glucose tolerance tests (OGTT; IVGTT), hyperinsulinemic-euglycemic clamps, and measurement of body fat between 29 and 36 weeks gestation and returned between 1 and 6 months postpartum for a 75-g OGTT. Logistic regression analysis was used to examine the relationship between antepartum variables and glucose tolerance status postpartum. At postpartum testing, 40% of the cohort had normal glucose tolerance, 50% had IGT, and 10% had diabetes by American Diabetes Association criteria. Independent antepartum predictors of postpartum diabetes were the 30-min incremental insulin:glucose ratio ...

OBJECTIVES: To identify, map, clone, and functionally validate a novel mouse model for impaired glucose tolerance and insulin secretion. RESEARCH DESIGN AND METHODS: Haploinsufficiency of the insulin receptor and associated mild insulin resistance has been used to sensitize an N-ethyl-N-nitrosourea (ENU) screen to identify novel mutations resulting in impaired glucose tolerance and diabetes. The new impaired glucose tolerance 4 (IGT4) model was selected using an intraperitoneal glucose tolerance test and inheritance of the phenotype confirmed by generation of backcross progeny. Segregation of the phenotype was correlated with genotype information to map the location of the gene and candidates sequenced for mutations. The function of the SRY-related high mobility group (HMG)-box 4 (Sox4) gene in insulin secretion was tested using another ENU allele and by small interfering RNA silencing in insulinoma cells. RESULTS: We describe two allelic autosomal dominant mutations in the highly conserved HMG box of

SUMMARY. Abnormal glucose tolerance tests and blunted plasma insulin responses returned to normal in three patients and improved in a fourth after removal of a pheochromocytoma. In two subjects phentolamine restored intravenous glucose tolerance curves to normal and improved the insulin secretion response to glucose. These findings suggest that alpha-receptor stimulation by catecholamines is important in causing glucose intolerance and blunted insulin secretion in patients with pheochromocytoma. Tumor removal was more effective than phentolamine in restoring plasma glucose and insulin levels to normal after glucose administration, suggesting that the inhibitory effects of phenochromocytoma on insulin secretion may not be mediated entirely through catecholamine stimulation of alpha-adrenergic receptors. ...

Author(s): Hivert, Marie-France; Cardenas, Andres; Allard, Catherine; Doyon, Myriam; Powe, Camille E; Catalano, Patrick M; Perron, Patrice; Bouchard, Luigi | Abstract: The placenta participates in maternal insulin sensitivity changes during pregnancy; however, mechanisms remain unclear. We investigated associations between maternal insulin sensitivity and placental DNA methylation markers across the genome. We analyzed data from 430 mother-offspring dyads in the Gen3G cohort. All women underwent 75-g oral glucose tolerance tests at ∼26 weeks of gestation; we used glucose and insulin measures to estimate insulin sensitivity (Matsuda index). At delivery, we collected samples from placenta (fetal side) and measured DNA methylation using Illumina EPIC arrays. Using linear regression models to quantify associations at 720,077 cytosine-guanine dinucleotides (CpGs), with adjustment for maternal age, gravidity, smoking, BMI, child sex, and gestational age at delivery, we identified 188 CpG sites where

BACKGROUND: Recent epidemiological and experimental data suggest a negative influence of shortened or disturbed night sleep on glucose tolerance. Due to the high prevalence of sleep disorders this might be a major health issue. However, no comparative studies of carbohydrate metabolism have been conducted in clinical sleep disorders. METHODOLOGY/PRINCIPAL FINDINGS: We performed oral glucose tolerance tests (OGTT) and assessed additional parameters of carbohydrate metabolism in patients suffering from obstructive sleep apnea syndrome (OSAS, N = 25), restless legs syndrome (RLS, N = 18) or primary insomnia (N = 21), and in healthy controls (N = 33). Compared to controls, increased rates of impaired glucose tolerance were found in OSAS (OR: 4.9) and RLS (OR: 4.7) patients, but not in primary insomnia patients (OR: 1.6). In addition, HbA1c values were significantly increased in the same two patient groups. Significant positive correlations were found between 2-h plasma glucose values measured during ...

How much does IFG, IGT, or the combination of both conditions increase the risk for subsequent development of diabetes? Does IFG and/or IGT increase the development of cardiovascular disease? If so, are the effects of IFG and/or IGT independent of associated known cardiovascular risk factors including the subsequent development of diabetes?. IFG and IGT represent intermediate states of abnormal glucose regulation that exist between normal glucose homeostasis and diabetes. IFG is now defined by an elevated fasting plasma glucose (FPG) concentration (≥100 and ,126 mg/dl) (29). IGT is defined by an elevated 2-h plasma glucose concentration (≥140 and ,200 mg/dl) after a 75-g glucose load on the oral glucose tolerance test (OGTT) in the presence of an FPG concentration ,126 mg/dl (29,30).. With the definitions above, there is overlap between the two groups.

AU - Kuo, Shi Wen. AU - Hsieh, Chang Hsun. AU - Lian, Wei Chen. AU - Lee, Chien Hsing. AU - Kao, Mei Teng. AU - Pei, Dee. PY - 2007/7/27. Y1 - 2007/7/27. N2 - Both impaired glucose tolerance (IGT) and impaired fasting glucose (IFG) are pre-diabetic states. IGT was defined as having normal fasting plasma glucose (,6.1 mmol/1) and abnormal 2-hr post-challenge plasma glucose. IFG was defined as having abnormal fasting plasma and normal 2-hr post-challenge plasma glucose (,7.8 mmol/1). To explore whether these two abnormalities share similar underlying pathophysiologies, we evaluated risk factors of IGT and IFT using the models of factor analysis. The present study included 107 subjects with IGT and 52 with IFG. An oral glucose tolerance test and insulin suppression test, which could quantify insulin ...

Undercarboxylated osteocalcin (ucOC) is reported to function as an endocrine hormone, affecting glucose metabolism in mice (1,2). Vitamin K, which converts ucOC to carboxylated osteocalcin (cOC), has been suggested to regulate glucose metabolism by modulating osteocalcin and/or proinflammatory pathway (3-5).. We studied whether modulation of ucOC via vitamin K2 supplementation for 4 weeks affects β-cell function and/or insulin sensitivity in healthy young male subjects. Forty-two healthy young male volunteers received vitamin K2 (menatetrenone; 30 mg; Eisai Co., Japan) or placebo t.i.d. for 4 weeks. Frequently sampled intravenous glucose tolerance test was performed to determine insulin sensitivity index (Si), acute insulin response to glucose (AIRg), and disposition index (DI) before and after treatment. Adiponectin, interleukin (IL)-6, C-reactive protein (CRP), ucOC, and cOC were measured before and after treatment.. After excluding frequently sampled intravenous glucose tolerance test ...

Objective: Hot environments are associated with impaired glucose metabolism at rest in healthy humans. The purpose of this study was to explore the contribution of key glucoregulatory hormones and biomarkers to this altered glucose tolerance. Methods: The effects of ambient temperature on glucose tolerance and its determinants were assessed with a 3-hr oral glucose tolerance test (OGTT) administered to 19 healthy young men and women at 22 °C and 31 °C. Results: The glucose response amplitude was greater in warm environment (AUC 904 ± 151 vs. 721 ± 89 mmol/l·180 min at 31 °C and 22 °C, respectively, p | .001). There was no significant effect of environmental temperature on insulin, growth hormone or pancreatic polypeptide concentrations (all p | .17). The cortisol response to the glucose load was reduced 30, 60, 90 and 120 minutes postload at 31 °C compared with 22 °C (p = .001). The interleukin-6 concentration was also lower in the session at 31 °C (p = .043). Conclusion: We conclude that

Introduction: Diabetes is a debilitating disease characterized by elevated blood glucose levels, which is rapidly r eaching endemic proportions throughout the world including Bangladesh. We had previously evaluated the antihyperglycemic potential of methanolic extract of aerial parts of Spilanthes calva and tubers of Colocasia esculenta. The objective of this study was to determine whether there is any synergistic antihyperglycemic activity between the methanolic extracts of the plant parts of the two plants.. Methods: Antihyperglycemic activity and synergistic potential were determined through oral glucose tolerance tests (OGTT) in mice.. Result: Administration of methanolic extract of aerial parts of S. calva (MESC) at a dose of 400 mg per kg body weight led to lowering of blood glucose levels in glucose-loaded mice in OGTT by 41.6%. At the same dose, methanolic extract of tubers of C. esculenta (MECE) lowered blood glucose levels by 25.1%. At doses of 100, 200 and 400 mg each of (MESC + ...

Diabetic ketoacidosis (DKA) during pregnancy is a serious complication in both mother and fetus. Most incidences occur during late pregnancy in women with type 1 diabetes mellitus. We report the rare case of a woman with type 1 diabetes mellitus who had normal glucose tolerance during the first trimester but developed DKA during late pregnancy. Although she had initially tested positive for screening of gestational diabetes mellitus during the first trimester, subsequent diagnostic 75-g oral glucose tolerance tests showed normal glucose tolerance. She developed DKA with severe general fatigue in late pregnancy. The patients general condition improved after treatment for ketoacidosis, and she vaginally delivered a healthy infant at term. The presence of DKA caused by the onset of diabetes should be considered, even if the patient shows normal glucose tolerance during the first trimester. ...

The aim of this study was to investigate the association between fasting duration before screening with 50g glucose challenge test (GCT) and the test outcome. For this cross-sectional study, we enrolled 508 low-risk pregnant women who underwent 50g GCT between the 24 and 28 weeks of gestation. We excluded women with pregestational diabetes, multiple gestations or a history of gestational diabetes mellitus (GDM), and macrosomia. We evaluated fasting durations, GCT results, and demographic features. A significant positive correlation was found between fasting duration and 50g GCT values (r=0.122; p=0.006), and the best cut-off value was found to be 6.5h, with 85.85% sensitivity and 38.61% specificity (relative risk, 2.73; 95% CI, 1.893-3.936; ...

We tested 32 routine clinical parameters for their ability to discriminate between a high risk and a low risk of non-insulin-dependent diabetes mellitus (NIDDM) within 5-7 years after pregnancies complicated by gestational diabetes mellitus (GDM). Latino women (n = 671) with GDM who did not have diabetes 4-16 weeks after delivery returned for at least one 75-g oral glucose tolerance test (OGTT) within 7.5 years. Multivariate analysis was used to identify parameters ascertained during or immediately after the index pregnancy that were independently associated with the development of diabetes during follow-up. Life table analysis revealed a 47% cumulative incidence rate of NIDDM 5 years after delivery for this cohort of patients who did not have diabetes at the initial postpartum examination. Four variables were identified as independent predictors of NIDDM: the area under the OGTT glucose curve at 4-16 weeks postpartum, the gestational age at the time of diagnosis of GDM, the area under the OGTT ...

We assessed the effect of the vasodilating calcium channel blocker nitrendipine on glucose tolerance in young spontaneously hypertensive rats (SHR) (n = 15). The nitrendipine group received 1 g/kg chow for 3 weeks. Untreated SHR (n = 14) served as controls. At 3 weeks body weight was comparable, whereas systolic blood pressure was 157 +/- 9 mm Hg in nitrendipine-treated rats versus 191 +/- 10 mm Hg in controls (mean +/- SD, P , .00001). Fasting glucose was 6.8 +/- 2.7 mmol/L in nitrendipine-treated versus 8.9 +/- 1.5 mmol/L in control rats (P , .03). An intravenous glucose tolerance test (300 mg/kg) showed plasma glucose levels at 2, 5, 15, and 30 minutes to be significantly lower in the nitrendipine-treated group versus controls (two-way ANOVA, P , .03). Glucose utilization was estimated by the uptake of [3H]deoxyglucose after its intravenous administration (2 microCi/100 g body wt) to instrumented awake animals. Heart and striated muscle uptake was, respectively, 7983 +/- 5812 and 951 +/- 731 ...

CONTEXT: The sexual dimorphism of the somatotroph axis has been documented, but whether the acromegaly-related metabolic alterations are gender-dependent has never been investigated. OBJECTIVE: The aim of the study was to evaluate the impact of gender on the metabolic parameters in acromegaly. DESIGN: We conducted a retrospective, comparative, multicenter study. PATIENTS: The 307 newly diagnosed acromegalic patients included in the study were grouped by gender: 157 men (aged 48.01 ± 14.28 yr), and 150 women (aged 48.67 ± 14.95 yr; of which 77 were premenopausal and 73 postmenopausal). OUTCOME MEASUREMENTS: We measured each component of the metabolic syndrome (MS), hemoglobin A1c, the areas under the curve (AUCs) of glucose and insulin during 2-h oral glucose tolerance test, basal insulin resistance using the homeostasis model assessment of the insulin resistance index, stimulated insulin sensitivity using the insulin sensitivity index, early insulin-secretion rate using the insulinogenic ...

OBJECTIVE: To assess the influence of strict metabolic control in women with insulin-treated gestational diabetes on the risk of large-for-gestational-age (LGA) newborns, the frequency of obstetrical complications and fetal outcome.. METHODS: In this prospective cohort study, 875 women were screened for gestational diabetes mellitus with a 75 g oral glucose tolerance test (OGTT) between weeks 24 and 28 of gestation. The study group (n = 162) consisted of women with insulin-treated gestational diabetes mellitus (GDM) and the control group (n = 713) of women with normal glucose tolerance (NGT). In the women with diabetes, strict adjustments of fasting glucose levels to 90 mg/dl and 130 mg/dl postprandially were achieved with insulin administration.. RESULTS: No increased risk for LGA newborns was observed in women with GDM and good metabolic control (16.7% vs. 12.3%; p = 0.1). In women with NGT, maternal prepregnancy BMI was significantly higher in those who delivered LGA newborns than in those ...

A progressive decline in circulating androgens was observed with advancing age. Patients 21-30 years old had lower plasma glucose and insulin levels, lower area under the oral glucose tolerance test curve and lower homeostasis model assessment of insulin resistance index, and higher glucose/insulin and quantitative insulin sensitivity check index than patients 31-39 years old. The prevalence of PCOS phenotypes changed with age. More specifically, the distribution of the phenotypes did not differ substantially between patients ≤20 years old and patients 21-30 years old. However, a decline in the prevalence of phenotype 1 (characterized by anovulation, hyperandrogenemia, and polycystic ovaries) and an increase in the prevalence of phenotype 4 (characterized by anovulation and polycystic ovaries without hyperandrogenemia) were observed in patients 31-39 years old.. Conclusion(s): ...

You have to remember though that these symptoms could also be found in other diseases. To confirm if you or someone in your family has diabetes, tests must be done. Currently, there are three lab tests used to establish a diagnosis of diabetes, namely, fasting plasma glucose test, oral glucose tolerance test, and random plasma glucose test. A random test displaying blood glucose level of 200 mg/dl or higher, plus the presence of the three symptoms, can indicate that a person has diabetes. Among the three, the Fasting Plasma Glucose test is the suggested test because it is most hassle-free and inexpensive. This will entail a blood extraction after a number of hours of not eating or drinking anything. But, Oral glucose tolerance test, though cumbersome given that it entails fasting and taking glucose orally, is more sensitive than the other tests for finding out if one has pre-diabetes. Diabetes is a major disease, and it can greatly affect ones quality of life if left unmanaged ...

Xanthosoma violaceum is commonly observed in fallow areas of Bangladesh but almost no scientific studies exist on this plant. Rural people consume the plant on a frequent basis. The objective of this study was to scientifically analyze the antinociceptive property of methanol extract of aerial parts of the plant along with antihyperglycemic activity. Antihyperglycemic activity was measured by oral glucose tolerance test (OGTT). Antinociceptive activity was determined by observed decreases in abdominal constrictions in intraperitoneally administered acetic acid-induced pain model in mice. Administration of methanol extract of aerial parts led to dose-dependent and significant reductions in blood glucose levels in glucose-loaded mice. At doses of 50, 100, 200 and 400 mg per kg body weight, the extract reduced blood sugar levels by 19.3, 23.2, 31.8, and 47.1%, respectively compared to control animals. By comparison, a standard antihyperglycemic drug, glibenclamide, when administered at a dose of 10 mg per

To identify distinct biological pathways of glucose metabolism, we conducted a systematic evaluation of biochemical changes after an oral glucose tolerance test (OGTT) in a community-based population. Metabolic profiling was performed on 377 nondiabetic Framingham Offspring cohort participants (mean age 57 years, 42% women, BMI 30 kg/m2) before and after OGTT. Changes in metabolite levels were evaluated with paired Student t tests, cluster-based analyses, and multivariable linear regression to examine differences associated with insulin resistance. Of 110 metabolites tested, 91 significantly changed with OGTT (P ≤ 0.0005 for all). Amino acids, β-hydroxybutyrate, and tricarboxylic acid cycle intermediates decreased after OGTT, and glycolysis products increased, consistent with physiological insulin actions. Other pathways affected by OGTT included decreases in serotonin derivatives, urea cycle metabolites, and B vitamins. We also observed an increase in conjugated, and a decrease in ...

The insulin tolerance test or ITT is a laboratory diagnostic test in which the individual receives insulin through an IV to check to see if the pituitary gland and the adrenal glands are functioning properly. Insulin tolerance tests are generally done by endocrinologists who are specialists in diabetes and other endocrine disorders.. The idea behind giving insulin injections is to allow the person to become extremely hypoglycemic (levels lower than 40 mg/dL or 2.2 mmol/l). Under normal conditions, the individual will release adrenocorticotropic hormone (ACTH) from the pituitary gland as well as growth hormone.. Elevated levels of ACTH and growth hormone trigger the adrenal glands to begin the stress response, which allows for the release of cortisol from the adrenal cortex. In normal people, cortisol and growth hormone counteract insulin and will raise the blood glucose level.. The insulin tolerance test is believed to be one of the best ways of telling whether the hypothalamic-pituitary-adrenal ...

Background: Adiponectin is an adipokine with beneficial effect on vascular function. Although adiponectin levels are decreased in patients with diabetes mellitus (DM), it is unclear whether impaired glucose tolerance (IGT) affects adiponectins release, or whether glucose intake modifies its release from adipocytes. We examined the effect of glucose on serum adiponectin/insulin and endothelial function, in subjects with IGT, patients with DM and healthy individuals.. Methods: The study population consisted of 113 subjects: 19 with IGT, 78 with DM and 16 controls. All subjects underwent glucose loading (75g oral glucose), and blood samples were obtained at baseline and after 3 hours. Endothelial function was evaluated by gauge-strain plethysmography at baseline and every 1h, and endothelium-dependent dilation (EDD) was determined. Adiponectin and insulin were measured at baseline and at 3h.. Results: Glucose loading increased adiponectin levels in healthy (70.1±8.5 to 80.8±11.4 ng/ml, p,0.05) ...

Various methods, including OGTT, have been used at different cystic fibrosis centres for the screening and diagnosis of CFRD. At the authors unit patients with cystic fibrosis have been screened for diabetes at least annually using RBG and HbA1c for some years. In this study we found that an abnormal RBG (,11.0 mmol/l), when used alone, has a poor sensitivity in the diagnosis of CFRD. In common with the study by Lanng and colleagues,5 we also found that an abnormal FBG and the presence of symptoms of hyperglycaemia when used alone have poor sensitivity in the diagnosis of CFRD. Lanng and colleagues reported that only 16% of their patients with OGTT defined diabetes had abnormal HbA1c. This is in contrast to 83% (95% CI 62 to 100) of our diabetic patients with abnormal HbA1c values. In the Danish study, ion exchange chromatography was used to measure HbA1c and a higher reference range was used (upper limit 6.4%). These differences are insufficient to explain the large differences in the ...

Aim To characterize lipid profiles in women with different gestational diabetes mellitus (GDM) physiologic subtypes. Methods We measured seven lipid markers (total cholesterol, LDL, HDL, triglycerides, non-esterified fatty acids (NEFA), ApoA, ApoB) in fasting plasma collected in a prospective cohort of 805 pregnant women during second trimester. We estimated insulin sensitivity and secretion using oral glucose tolerance test-based validated indices. We categorized GDM physiologic subtypes by insulin sensitivity and secretion defects defined as values below the 25th percentile among women with normal glucose tolerance (NGT), as previously established. We compared lipid markers across NGT and GDM subtypes. We explored associations between lipid markers and newborn anthropometry in the overall group and stratified by glucose tolerance status. Results Among 805 women, 67 (8.3%) developed GDM. Women with GDM had higher body mass index (BMI; 29.3 vs. 26.6 kg/m2), while ethnicity (97.3% vs. 97.0% ...

Antagonism of the glucagon receptor (GCGR) is associated with increased circulating levels of glucagon-like peptide-1 (GLP-1). To investigate the contribution of GLP-1 to the antidiabetic actions of GCGR antagonism, we administered an anti-GCGR monoclonal antibody (mAb B) to wild-type mice and GLP-1 receptor knockout (GLP-1R KO) mice. Treatment of wild-type mice with mAb B lowered fasting blood glucose, improved glucose tolerance, and enhanced glucose-stimulated insulin secretion during an intraperitoneal glucose tolerance test (ipGTT). In contrast, treatment of GLP-1R KO mice with mAb B had little efficacy during an ipGTT. Furthermore, pretreatment with the GLP-1R antagonist exendin-(9-39) diminished the antihyperglycemic effects of mAb B in wild-type mice. To determine the mechanism whereby mAb B improves glucose tolerance, we generated a monoclonal antibody that specifically antagonizes the human GLP-1R. Using a human islet transplanted mouse model, we demonstrated that pancreatic islet ...

BACKGROUND: The expression of interleukin-1-receptor antagonist is reduced in pancreatic islets of patients with type 2 diabetes mellitus, and high glucose concentrations induce the production of interleukin-1beta in human pancreatic beta cells, leading to impaired insulin secretion, decreased cell proliferation, and apoptosis. METHODS: In this double-blind, parallel-group trial involving 70 patients with type 2 diabetes, we randomly assigned 34 patients to receive 100 mg of anakinra (a recombinant human interleukin-1-receptor antagonist) subcutaneously once daily for 13 weeks and 36 patients to receive placebo. At baseline and at 13 weeks, all patients underwent an oral glucose-tolerance test, followed by an intravenous bolus of 0.3 g of glucose per kilogram of body weight, 0.5 mg of glucagon, and 5 g of arginine. In addition, 35 patients underwent a hyperinsulinemic-euglycemic clamp study. The primary end point was a change in the level of glycated hemoglobin, and secondary end points were ...

Institutions: Diabetes QTL and Modifier Loci Group, Medical Research Council Our aim is to identify novel genes that contribute to glucose regulation and its pathologies including impaired glucose tolerance and type 2 diabetes in humans and other mammals. Our approach uses a whole genome mapping approach to identify mouse loci that cosegregate with and by implication determine two biochemical phenotypes (plasma glucose and plasma insulin levels) that are perturbed in diabetes. We surveyed 4 inbred mouse strains (C57BL/6J, C3H, DBA/2 and BALB/C) for variation in glucose tolerance during an intraperitoneal glucose tolerance test. We observed larger strain differences in male than female mice. Male C57BL/6J mice were significantly less glucose tolerant than other strains (N=20, ...

Although subclinical inflammation and oxidative stress are implicated in the aetiology of diabetes, there are hardly any studies in prediabetes. Therefore, we made an attempt to study the gene expression pattern of certain inflammatory/oxidative genes using lymphocytes from Type 2 diabetic patients, impaired glucose tolerance (IGT), and normal glucose tolerance (NGT) subjects. Compared to NGT group, interleukin-6, tumor necrosis factor-α (TNF-α), p22Phox NADPH oxidase, and thioredoxin interacting protein (TXNIP) mRNA levels were higher and suppressor of cytokine signaling (SOCS-3) mRNA was lower in subjects with IGT and diabetes. The mean (±SE) levels of thiobarbituric acid reactive substances and protein carbonyl content were also elevated in glucose intolerant subjects. In multiple linear regression analysis, TXNIP and TNF-α showed a significant association with HbA1c even after adjusting for TBARS and PCO (TXNIP: β = 1.70, P , 0.01; TNF-α: β = 1.86, P , 0.01). Increased subclinical ...

AIMS: Women who had gestational diabetes mellitus (GDM) have a high risk of type 2 diabetes mellitus (T2DM) in the years following pregnancy. Most follow-up screening studies have been conducted in limited geographical areas leading to large variability in the results. The aim of our investigation was to measure how the publication of guidelines affected early screening for T2DM after a pregnancy with GDM during the period 2007-2013, in France. METHODS: We conducted a retrospective cohort study in a representative sample of 1/97th of the French population using data from the National Health Insurance Inter-Regime Information System, which collects individual hospital and non-hospital data for healthcare consumption. RESULTS: The sample included 49,080 women who gave birth in 2007-2013. In the following 3 months, only 18.49% of women with GDM had an oral glucose tolerance test or a blood glucose test in 2007. This rate had not significantly increased in 2013 (p = 0.18). The proportion of

Hemoglobin A1C is an indicator of average blood glucose control over two to three months and is correlated to an individuals risk of developing diabetic complications such as diseases of the eye, kidney and nerves.. In a pilot study, twenty adults with diabetes who were taking oral diabetes medications were randomly assigned to receive either Diabetinol or a placebo twice per day for three months. Each subject had mildly to moderately elevated cholesterol levels at the start of the study as well.. After 84 days, the group receiving Diabetinol showed a significant 19 percent reduction in glucose intolerance measured as peak changes in blood glucose over the four hours of a standard oral glucose challenge. The placebo group showed no significant improvements in glucose intolerance. A standard glucose challenge involves ingesting 100 grams of glucose and having blood glucose measurements after 30 minutes and hourly for four hours. Neither the investigators nor the volunteers knew who was receiving ...

Recent data suggest that the gut microbiota plays a significant role in fat accumulation. However, it is not clear whether gut microbiota is involved in the pathophysiology of type 2 diabetes. To assess this issue, we modulated gut microbiota via antibiotics administration in two different mouse models with insulin resistance. Results from dose-determination studies showed that a combination of norfloxacin and ampicillin, at a dose of 1 g/L, maximally suppressed the numbers of cecal aerobic and anaerobic bacteria in ob/ob mice. After a 2-wk intervention with the antibiotic combination, both ob/ob and diet-induced obese and insulin-resistant mice showed a significant improvement in fasting glycemia and oral glucose tolerance. The improved glycemic control was independent of food intake or adiposity because pair-fed ob/ob mice were as glucose intolerant as the control ob/ob mice. Reduced liver triglycerides and increased liver glycogen correlated with improved glucose tolerance in the treated mice.
