The diagnosis of diabetes mellitus by the available criteria is controversial and relies heavily on fasting glucose results. This cross-sectional study in 2010-2011 aimed to measure the frequency of impaired glucose tolerance and diabetes mellitus in 127 subjects having fasting blood glucose < 7.0 mmol/L and to measure the agreement between different standard diagnostic criteria. Subjects presenting to a laboratory for analysis of fasting blood glucose for excluding diabetes mellitus underwent a 2-hour 75 g oral glucose challenge. A total of 40.6% of subjects with fasting blood glucose from 5.6-6.0 mmol/L had abnormal glucose regulation on the basis ofthe gold standard glucose challenge. Agreement between American Diabetes Association and World Health Organization diagnostic criteria was only fair (kappa = 0.32). Abnormalities of glucose metabolism including impaired glucose tolerance and diabetes mellitus can exist at fasting blood glucose results < 6.1 mmol/L (110 mg/dL).

To describe current practices for screening for gestational diabetes mellitus in the Cook Islands and consider the implications of alternative screening strategies. Eligible women had antenatal care from January 2009 to December 2012. A non-fasting 50 g glucose challenge between 24 and 28 weeks gestation (positive if 1-hour glucose greater than or equal to 7.8 mmol/L) was followed by a 75 g oral glucose tolerance test (gestational diabetes mellitus diagnosed if fasting glucose greater than or equal to 5.2 mmol/L or 2-hour glucose greater than or equal to 8.0 mmol/L; pregnancy impaired glucose tolerance if positive screen and negative diagnostic test). Uptake of the screening programme rose from 49.0% to 99.6% by the end of the study period. 646 women had a glucose challenge; for 186/646 (28.8%) the challenge was positive; 183 had an oral glucose tolerance test; 89/646 (13.8%) had pregnancy impaired glucose tolerance; 94/646 (13.9%) had gestational diabetes mellitus. Median maternal weight gain was 6 kg (gestational diabetes mellitus) and 10 kg (normal glucose tolerance); caesarean section rates were 25% and 11% respectively; baby birthweights were not significantly different. 59 women with gestational diabetes mellitus had a post-natal glucose tolerance test at their 6-week check and 21 (35.6%) had diabetes confirmed. The gestational diabetes mellitus screening programme has a high uptake and current management appears effective in reducing maternal and fetal weight gain. A proposed new screening programme is outlined.

Incidence of type 1 diabetes mellitus is increasing worldwide. Monitoring glycaemia is essential for control of diabetes mellitus. Conventional blood-based measurement of glucose requires venepuncture or needle prick, which is not free from pain and risk of infection. The non-invasiveness, ease and low-cost in collection made saliva an attractive alternative sample. The objective of this review was to systematically review the evidence on the relationship between salivary glucose level and blood glucose level in monitoring glycaemia in patients with type 1 diabetes mellitus. We searched studies which evaluate salivary glucose levels and serum glycaemia in type 1 diabetes mellitus in electronic databases of MEDLINE, EMBASE, Ovid and Google Scholar. We selected the eligible studies, following the inclusion criteria set for this review. Due to heterogeneity of studies, we conducted qualitative synthesis of studies. Ten observational studies were included in this review, including a total of 321 cases and 323 controls with ages between 3 and 61 years and the majority were males (62%). Two studies were done exclusively on children below 17 years old. The significant difference between salivary glucose levels in type 1 diabetes mellitus and controls were reported in 6 studies with 8 data sets. Five studies with 7 datasets reported the correlation coefficient between salivary glucose and blood glucose in patients with diabetes. Findings suggest that salivary glucose concentrations may be helpful in monitoring glycaemia in type 1 diabetes mellitus. However, the utility of using salivary glucose level to monitor glycaemia should be evaluated in future well designed, prospective studies with adequate number of participants with type 1 diabetes mellitus.

To explore the characteristics of diabetes mellitus in adults with Turner syndrome. Observational study consisting of a prospective phase after the access of adults with Turner syndrome to the Endocrinology Unit (median period of follow-up 15.6, interquartile range: 12.0-24.5 months) and a retrospective collection of data from the diagnosis of Turner syndrome until the time of access to the Endocrinology Unit. A total of 113 Italian Turner syndrome patients were included in the study. During the prospective phase of the study, each patient underwent physical examination, fasting blood sampling, and an oral glucose tolerance test on a yearly basis. Oral glucose tolerance test was used to perform the diagnosis of diabetes mellitus. Before access to the Endocrinology Unit, diabetes mellitus was diagnosed in two Turner syndrome patients. Another five cases of diabetes mellitus were diagnosed at the first access to the Endocrinology Unit, whereas seven new cases of diabetes mellitus were diagnosed during the prospective phase of the study. At the diagnosis of diabetes mellitus, only one patient had fasting glucose above 126 mg/dL, and only two had an HbA1c value >6.5% (48 mmol/mol). When compared to normo-glucose tolerant patients, the diabetic patients had a significantly lower insulin-to-glucose ratio at 30 and 60 min of the oral glucose tolerance test. In the regression analyses, only age was associated with the development of diabetes mellitus. This study confirms that diabetes mellitus is frequent in Turner syndrome and suggests that it is specific to the syndrome. In addition, this study demonstrates that oral glucose tolerance test is a more sensitive test than HbA1c for the diagnosis of diabetes mellitus in Turner syndrome.

Several techniques have been used to determine body composition during pregnancy. To determine the characteristics of body composition in women with gestational diabetes mellitus in comparison with women with normal glucose tolerance and pre-gestacional diabetes. Pregnant women with gestational diabetes mellitus, pre-gestacional diabetes, and normal glucose tolerance, between 24 to 32 weeks of single gestation, were enrolled in a cross-sectional study. Screening of DMG was carried out using 50 g of glucose load; diagnosis was confirmed by oral glucose tolerance test. Evaluation of body composition was carried out by bioelectrical impedance. The Kruskal Wallis test was used for statistical analysis. A total of 79 women were included; of these, diagnosis of gestational diabetes mellitus, pre-gestacional diabetes, and normal glucose tolerance was established in 14, 9, and 56 women, respectively. Pre-gestational body mass index was greater in women with diabetes (p < 0.01). Fat free mass and total body water were similar in the studied groups. Fat mass was greater in women with gestational diabetes mellitus (range 21.0-29.4 kg) and patients with pre-gestacional diabetes (range 26.4-32.7 kg) than in the women with normal glucose tolerance (range 150.8-25.9 kg), p < 0.01. The body composition of women, between 24 to 32 weeks of single gestation, is different in the women with gestational diabetes mellitus compared with women with normal glucose tolerance. Women with gestational diabetes mellitus show a significant increase in fat mass without significant changes in the fat free mass and total body water.

Diabetes mellitus is a group of diseases associated with various metabolic disorders, the main feature of which is chronic hyperglycemia due to insufficient insulin action. Its pathogenesis involves both genetic and environmental factors. The long-term persistence of metabolic disorders can cause susceptibility to specific complications and also foster arteriosclerosis. Diabetes mellitus is associated with a broad range of clinical presentations, from being asymptomatic to ketoacidosis or coma, depending on the degree of metabolic disorder. CLASSIFICATION TABLES 1 AND 2 AND FIGURE 1: [Table: see text] [Table: see text] Figure 1 A scheme of the relationship between etiology (mechanism) and patho-physiological stages (states) of diabetes mellitus. Arrows pointing right represent worsening of glucose metabolism disorders (including onset of diabetes mellitus). Among the arrow lines, indicates the condition classified as 'diabetes mellitus'. Arrows pointing left represent improvement in the glucose metabolism disorder. The broken lines indicate events of low frequency. For example, in type 2 diabetes mellitus, infection can lead to ketoacidosis and require temporary insulin treatment for survival. Also, once diabetes mellitus has developed, it is treated as diabetes mellitus regardless of improvement in glucose metabolism, therefore, the arrow lines pointing left are filled in black. In such cases, a broken line is used, because complete normalization of glucose metabolism is rare.imageThe classification of glucose metabolism disorders is principally derived from etiology, and includes staging of pathophysiology based on the degree of deficiency of insulin action. These disorders are classified into four groups: (i) type 1 diabetes mellitus; (ii) type 2 diabetes mellitus; (iii) diabetes mellitus due to other specific mechanisms or diseases; and (iv) gestational diabetes mellitus. Type 1 diabetes is characterized by destruction of pancreatic β-cells. Type 2 diabetes is characterized by combinations of decreased insulin secretion and decreased insulin sensitivity (insulin resistance). Glucose metabolism disorders in category (iii) are divided into two subgroups; subgroup A is diabetes in which a genetic abnormality has been identified, and subgroup B is diabetes associated with other pathologic disorders or clinical conditions. The staging of glucose metabolism includes normal, borderline and diabetic stages depending on the degree of hyperglycemia occurring as a result of the lack of insulin action or clinical condition. The diabetic stage is then subdivided into three substages: non-insulin- requiring, insulin-requiring for glycemic control, and insulin-dependent for survival. The two former conditions are called non-insulin-dependent diabetes and the latter is known as insulin-dependent diabetes. In each individual, these stages may vary according to the deterioration or the improvement of the metabolic state, either spontaneously or by treatment. DIAGNOSIS TABLES 3–7 AND FIGURE 2: [Table: see text] [Table: see text] [Table: see text] [Table: see text] [Table: see text] Figure 2 Flow chart outlining steps in the clinical diagnosis of diabetes mellitus. *The value for HbA1c (%) is indicated with 0.4% added to HbA1c (JDS) (%).imageCategories of the State of Glycemia: Confirmation of chronic hyperglycemia is essential for the diagnosis of diabetes mellitus. When plasma glucose levels are used to determine the categories of glycemia, patients are classified as having a diabetic type if they meet one of the following criteria: (i) fasting plasma glucose level of ≥126 mg/dL (≥7.0 mmol/L); (ii) 2-h value of ≥200 mg/dL (≥11.1 mmol/L) in 75 g oral glucose tolerance test (OGTT); or (iii) casual plasma glucose level of ≥200 mg/dL (≥11.1 mmol/L). Normal type is defined as fasting plasma glucose level of <110 mg/dL (<6.1 mmol/L) and 2-h value of <140 mg/dL (<7.8 mmol/L) in OGTT. Borderline type (neither diabetic nor normal type) is defined as falling between the diabetic and normal values. According to the current revision, in addition to the earlier listed plasma glucose values, hemoglobin A1c (HbA1c) has been given a more prominent position as one of the diagnostic criteria. That is, (iv) HbA1c≥6.5% is now also considered to indicate diabetic type. The value of HbA1c, which is equivalent to the internationally used HbA1c (%) (HbA1c [NGSP]) defined by the NGSP (National Glycohemoglobin Standardization Program), is expressed by adding 0.4% to the HbA1c (JDS) (%) defined by the Japan Diabetes Society (JDS). Subjects with borderline type have a high rate of developing diabetes mellitus, and correspond to the combination of impaired fasting glucose (IFG) and impaired glucose tolerance (IGT) noted by the American Diabetes Association (ADA) and WHO. Although borderline cases show few of the specific complications of diabetes mellitus, the risk of arteriosclerosis is higher than those of normal type. When HbA1c is 6.0-6.4%, suspected diabetes mellitus cannot be excluded, and when HbA1c of 5.6-5.9% is included, it forms a group with a high risk for developing diabetes mellitus in the future, even if they do not have it currently. Clinical Diagnosis: 1 If any of the criteria for diabetic type (i) through to (iv) is observed at the initial examination, the patient is judged to be 'diabetic type'. Re-examination is conducted on another day, and if 'diabetic type' is reconfirmed, diabetes mellitus is diagnosed. However, a diagnosis cannot be made only by the re-examination of HbA1c alone. Moreover, if the plasma glucose values (any of criteria [i], [ii], or [iii]) and the HbA1c (criterion [iv]) in the same blood sample both indicate diabetic type, diabetes mellitus is diagnosed based on the initial examination alone. If HbA1c is used, it is essential that the plasma glucose level (criteria [i], [ii] or [iii]) also indicates diabetic type for a diagnosis of diabetes mellitus. When diabetes mellitus is suspected, HbA1c should be measured at the same time as examination for plasma glucose.2 If the plasma glucose level indicates diabetic type (any of [i], [ii], or [iii]) and either of the following conditions exists, diabetes mellitus can be diagnosed immediately at the initial examination.• The presence of typical symptoms of diabetes mellitus (thirst, polydipsia, polyuria, weight loss)• The presence of definite diabetic retinopathy3 If it can be confirmed that the above conditions 1 or 2 existed in the past, diabetes mellitus can be diagnosed or suspected regardless of the current test results.4 If the diagnosis of diabetes cannot be established by these procedures, the patient is followed up and re-examined after an appropriate interval.5 The physician should assess not only the presence or absence of diabetes, but also its etiology and glycemic stage, and the presence and absence of diabetic complications or associated conditions. Epidemiological Study: For the purpose of estimating the frequency of diabetes mellitus, 'diabetes mellitus' can be substituted for the determination of 'diabetic type' from a single examination. In this case, HbA1c≥6.5% alone can be defined as 'diabetes mellitus'. Health Screening: It is important not to misdiagnose diabetes mellitus, and thus clinical information such as family history and obesity should be referred to at the time of screening in addition to an index for plasma glucose level. Gestational Diabetes Mellitus: There are two hyperglycemic disorders in pregnancy: (i) gestational diabetes mellitus (GDM); and (ii) diabetes mellitus. GDM is diagnosed if one or more of the following criteria is met in a 75 g OGTT during pregnancy: 1 Fasting plasma glucose level of ≥92 mg/dL (5.1 mmol/L)2 1-h value of ≥180 mg/dL (10.0 mmol/L)3 2-h value of ≥153 mg/dL (8.5 mmol/L) However, diabetes mellitus that is diagnosed by the clinical diagnosis of diabetes mellitus defined earlier is excluded from GDM.

Diabetes mellitus is one of the leading diseases in the developed world. In order to better regulate blood glucose in a diabetic patient, improved modelling of insulin-glucose dynamics is a key factor in the treatment of diabetes mellitus. In the current work, the insulin-glucose dynamics in type II diabetes mellitus can be modelled by using a stochastic nonlinear state-space model. Estimating the parameters of such a model is difficult as only a few blood glucose and insulin measurements per day are available in a non-clinical setting. Therefore, developing a predictive model of the blood glucose of a person with type II diabetes mellitus is important when the glucose and insulin concentrations are only available at irregular intervals. To overcome these difficulties, we resort to online sequential Monte Carlo (SMC) estimation of states and parameters of the state-space model for type II diabetic patients under various levels of randomly missing clinical data. Our results show that this method is efficient in monitoring and estimating the dynamics of the peripheral glucose, insulin and incretins concentration when 10, 25 and 50% of the simulated clinical data were randomly removed.

Type 2 diabetes mellitus in Navajo adolescents.
Kim, C; McHugh, C; Kwok, Y; Smith, A
1999-01-01
Diabetes mellitus afflicts over one-fifth of the Navajo population aged over 20 years, but the prevalence of diabetes in Navajo adolescents is unclear. We conducted voluntary testing for diabetes mellitus at two high schools on the Navajo reservation to clarify the prevalence as well as to assess the utility of a high-school based screening program. Body mass index measurements (BMI), oral glucose tolerance tests, and hemoglobin A1C measurements were obtained in consenting high school students. Of the 276 students that participated, 234 were Navajo. Only one Navajo student (0.4%) had diabetes mellitus, although eight (3%) had impaired glucose tolerance or impaired fasting glucose. Participant BMI did not differ significantly from nonparticipant BMI. No correlation existed between BMI or impaired glucose handling, and significant overlap existed between the hemoglobin A1C values of students with impaired glucose handling and students without impaired glucose handling. Increased participation in screening programs may reveal higher disease prevalence, but high school-based screening is not justified by this study, despite the high rates of diabetes mellitus in the Navajo population.

Diabetes in Patients With Acromegaly.
Hannon, A M; Thompson, C J; Sherlock, M
2017-02-01
Acromegaly is a clinical syndrome which results from growth hormone excess. Uncontrolled acromegaly is associated with cardiovascular mortality, due to an excess of risk factors including diabetes mellitus, hypertension and cardiomegaly. Diabetes mellitus is a frequent complication of acromegaly with a prevalence of 12-37%. This review will provide an overview of a number of aspects of diabetes mellitus and glucose intolerance in acromegaly including the following: 1. Epidemiology and pathophysiology of abnormalities of glucose homeostasis 2. The impact of different management options for acromegaly on glucose homeostasis 3. The management options for diabetes mellitus in patients with acromegaly RECENT FINDINGS: Growth hormone and IGF-1 have complex effects on glucose metabolism. Insulin resistance, hyperinsulinaemia and increased gluconeogenesis combine to produce a metabolic milieu which leads to the development of diabetes in acromegaly. Treatment of acromegaly should ameliorate abnormalities of glucose metabolism, due to reversal of insulin resistance and a reduction in gluconeogenesis. Recent advances in medical therapy of acromegaly have varying impacts on glucose homeostasis. These adverse effects influence management choices in patients with acromegaly who also have diabetes mellitus or glucose intolerance. The underlying mechanisms of disorders of glucose metabolism in patients with acromegaly are complex. The aim of treatment of acromegaly is normalisation of GH/IGF-1 with reduction of co-morbidities. The choice of therapy for acromegaly should consider the impact of therapy on several factors including glucose metabolism.

The aim of this study was to compare the ability of American Diabetes Association (ADA) diagnostic criteria to identify U.S. Hispanics/Latinos from diverse heritage groups with probable diabetes mellitus and assess cardiovascular risk factor correlates of those criteria. Cross-sectional analysis of data from 15,507 adults from 6 Hispanic/Latino heritage groups, enrolled in the Hispanic Community Health Study/Study of Latinos. The prevalence of probable diabetes mellitus was estimated using individual or combinations of ADA-defined cut points. The sensitivity and specificity of these criteria at identifying diabetes mellitus from ADA-defined prediabetes and normoglycemia were evaluated. Prevalence ratios of hypertension, abnormal lipids, and elevated urinary albumin-creatinine ratio for unrecognized diabetes mellitus-versus prediabetes and normoglycemia-were calculated. Among Hispanics/Latinos (mean age, 43 years) with diabetes mellitus, 39.4% met laboratory test criteria for probable diabetes, and the prevalence varied by heritage group. Using the oral glucose tolerance test as the gold standard, the sensitivity of fasting plasma glucose (FPG) and hemoglobin A1c-alone or in combination-was low (18, 23, and 33%, respectively) at identifying probable diabetes mellitus. Individuals who met any criterion for probable diabetes mellitus had significantly higher (P<.05) prevalence of most cardiovascular risk factors than those with normoglycemia or prediabetes, and this association was not modified by Hispanic/Latino heritage group. FPG and hemoglobin A1c are not sensitive (but are highly specific) at detecting probable diabetes mellitus among Hispanics/Latinos, independent of heritage group. Assessing cardiovascular risk factors at diagnosis might prompt multitarget interventions and reduce health complications in this young population. 2hPG = 2-hour post-glucose load plasma glucose ADA = American Diabetes Association BMI = body mass index CV = cardiovascular FPG = fasting plasma glucose HbA1c = hemoglobin A1c HCHS/SOL = Hispanic Community Health Study/Study of Latinos HDL-C = high-density-lipoprotein cholesterol NGT = normal glucose tolerance NHANES = National Health and Nutrition Examination Survey OGTT = oral glucose tolerance test TG = triglyceride UACR = urine albumin-creatinine ratio.

The mechanisms and therapeutic potential of SGLT2 inhibitors in diabetes mellitus.
Vallon, Volker
2015-01-01
The kidneys in normoglycemic humans filter 160-180 g of glucose per day (∼30% of daily calorie intake), which is reabsorbed and returned to the systemic circulation by the proximal tubule. Hyperglycemia increases the filtered and reabsorbed glucose up to two- to three-fold. The sodium glucose cotransporter SGLT2 in the early proximal tubule is the major pathway for renal glucose reabsorption. Inhibition of SGLT2 increases urinary glucose and calorie excretion, thereby reducing plasma glucose levels and body weight. The first SGLT2 inhibitors have been approved as a new class of antidiabetic drugs in type 2 diabetes mellitus, and studies are under way to investigate their use in type 1 diabetes mellitus. These compounds work independent of insulin, improve glycemic control in all stages of diabetes mellitus in the absence of clinically relevant hypoglycemia, and can be combined with other antidiabetic agents. By lowering blood pressure and diabetic glomerular hyperfiltration, SGLT2 inhibitors may induce protective effects on the kidney and cardiovascular system beyond blood glucose control.

Type 2 diabetes mellitus as a disorder of galanin resistance.
Fang, Penghua; Shi, Mingyi; Zhu, Yan; Bo, Ping; Zhang, Zhenwen
2016-01-01
The increasing prevalence of type 2 diabetes mellitus with its high morbidity and mortality becomes an important health problem. The multifactorial etiology of type 2 diabetes mellitus is relative to many gene and molecule alterations, and increased insulin resistance. Besides these, however, there are still other predisposing and risk factors accounting for type 2 diabetes mellitus not to be identified and recognized. Emerging evidence indicated that defects in galanin function played a crucial role in development of type 2 diabetes mellitus. Galanin homeostasis is tightly relative to insulin resistance and is regulated by blood glucose. Hyperglycemia, hyperinsulinism, enhanced plasma galanin levels and decreased galanin receptor activities are some of the characters of type 2 diabetes mellitus. The discrepancy between high insulin level and low glucose handling is named as insulin resistance. Similarly, the discrepancy between high galanin level and low glucose handling may be denominated as galanin resistance too. In this review, the characteristic milestones of type 2 diabetes mellitus were condensed as two analogical conceptual models, obesity-hyper-insulin-insulin resistance-type 2 diabetes mellitus and obesity-hyper-galanin-galanin resistance-type 2 diabetes mellitus. Both galanin resistance and insulin resistance are correlative with each other. Conceptualizing the etiology of type 2 diabetes mellitus as a disorder of galanin resistance may inspire a new concept to deepen our knowledge about pathogenesis of type 2 diabetes mellitus, eventually leading to novel preventive and therapeutic interventions for type 2 diabetes mellitus.

The study objective was to investigate the predictability and risk factors for the development of new-onset type 2 diabetes mellitus after transplant in the Saudi population. This was a retrospective observational cohort study in adult kidney transplant recipients who developed new-onset type 2 diabetes mellitus after transplant. Patients with and without new-onset type 2 diabetes mellitus after transplant were compared for demographic factors, blood glucose levels at 4-hour intervals for 24 hours after transplant, and serum creatinine levels at 6 and 12 months after transplant. Of 279 patients included in our study, 15.5% developed new-onset type 2 diabetes mellitus after a mean follow-up of 4.6 ± 2.1 years after transplant. Patients with new-onset type 2 diabetes mellitus after transplant were significant older (P = .001), had a higher body mass index (P = .001), and had higher fasting blood glucose levels 24 hours after transplant (P = .03). No significant differences were observed regarding sex, transplant type, or serum creatinine levels at 6 and 12 months. Risk factors for new-onset type 2 diabetes mellitus after transplant are body mass index (P = .001; relative risk of 1.26), fasting blood glucose at 24 hours (P = .001; relative risk of 1.3), age (P = .001; relative risk of 1.44), and family history of diabetes mellitus (P = .001; relative risk of 31.3). Risk factors for developing new-onset type 2 diabetes mellitus were age, heavier weight, body mass index, family history of diabetes mellitus, and having higher fasting blood glucose levels 24 hours after transplant, with family history of diabetes mellitus being an especially very high significant risk factor.

SERUM magnesium levels as an indicator of status of Diabetes Mellitus type 2.
Ramadass, S; Basu, Sharbari; Srinivasan, A R
2015-01-01
Magnesium deficiency is commonly associated with endocrine and metabolic disorders, especially with Diabetes Mellitus type 2 though the mechanism of hypomagnesemia in Diabetes Mellitus is not completely known. There is a close association between metabolic control of Diabetes Mellitus and impaired magnesium balance. To estimate the serum levels of magnesium in patients of with Diabetes Mellitus type 2 and to find a correlation if any, with the duration and control (by estimating HbA1c) of Diabetes Mellitus type 2. Fifty patients of Diabetes Mellitus type 2 were included in the study. Blood samples were analyzed for fasting and post prandial glucose, HbA1c and magnesium. The patients were grouped into three categories based upon their HbA1c levels into those with good control, need intervention and poor control. The three groups were compared with reference to their mean levels of blood glucose and magnesium. Association of serum magnesium levels with HbA1c, Fasting and postprandial blood glucose and duration of Diabetes Mellitus was also done. Serum magnesium levels were found to decline with rise in HbA1c levels and with duration of Diabetes Mellitus type 2. Hypomagnesemia is linked to poor control of Diabetes Mellitus type 2 and depletion of serum magnesium occurs exponentially with duration of disease. Copyright © 2014 Diabetes India.

Determination of insulin injection dose in diabetes mellitus treatment can be considered as an optimal control problem. This article is aimed to simulate optimal blood glucose control for patient with diabetes mellitus. The blood glucose regulation of diabetic patient is represented by Ackerman’s Linear Model. This problem is then solved using dynamic programming method. The desired blood glucose level is obtained by minimizing the performance index in Lagrange form. The results show that dynamic programming based on Ackerman’s Linear Model is quite good to solve the problem.

Our research is focused on the incidence of diabetes mellitus and glucose metabolic disorders among oral cancer patients and the frequency of different oral localizations of cancer. Diabetes mellitus affects 7% of the Hungarian population. This study uses data spanning 14 years, with 2 datasets of 1998-1999 and 2012-2013, collected first hand by the authors. These datasets have led us to examine the blood glucose level in 267 patients with histologically confirmed malignant tumours in the oral cavity. Diabetes mellitus was found in 59 of them (22.1%), The blood glucose was elevated in 32 cases (12%). The most frequent tumor locations among the diabetic patients: labial, lingual and gingival tumors gingivae. Comparative epidemiological study demonstrates that in 2012-2013 dataset there was an increased observed percentage of people with diabetes mellitus [17.6% to 22.1%]. The percentage of patients with IFG (impaired fasting glucose) also increased from 9.8% to 12%. Overall the number of patients with glucose metabolic disorders climbed from 27.4% to 34.1%, (p > 0.05). Our intention of this introductory analysis is to emphasize the close connection of these two very important disease groups, and the wider spread of diabetes mellitus.

D-Tagatose (D-tag), a hexose bulk sweetener, does not affect plasma glucose levels when orally administered to rodents. Additionally, D-tag attenuates the rise in plasma glucose after mice are administered oral sucrose. The current study was undertaken to investigate the acute glycaemic effects of oral D-tag alone or in combination with oral glucose in human subjects with and without type 2 diabetes mellitus. Glycaemic responses to D-tag also were investigated in subjects after oral sucrose to examine whether the glucose-lowering effects of D-tag in rodents may result from a direct inhibition of intestinal disaccharidases. Eight normal and eight subjects with diabetes mellitus were administered 75 g of glucose, 75 g of D-tag, or 75 g of D-tag 30 min prior to a 75 g oral glucose tolerance test (OGTT). Five patients with diabetes mellitus were challenged with a 75 g oral sucrose tolerance test (OSTT) with and without oral pre-treatment with 75 g of D-tag. Patients with diabetes mellitus also received separate 0, 10, 15, 20 and 30 g of D-tag 30 min prior to a 75 g OGTT. Oral loading with D-tag alone led to no changes in glucose or insulin levels in either normal patients or those with diabetes mellitus. Pre-OGTT treatment with 75 g D-tag, however, attenuated the rise in glucose levels in patients with diabetes mellitus (p < 0.02 at 60 and 180 min, and p < 0.01 at 120 min). The glucose area under the curve (AUC) was reduced significantly also by pre-treatment with D-tag in a dose-dependent manner in patients with diabetes mellitus (p < 0.05 for 10 g D-tag, p < 0.001 for 20 g D-tag, and p = 0.0001 for 30 g D-tag). In patients with diabetes mellitus 75 g D-tag similarly attenuated the rise in glucose following an OSTT (p < 0.01 at 30 min, and p < 0.02 at 60 min). Pre-treatment with 75 g D-tag also tended to blunt the rise in insulin following an OGTT in normal patients (p = 0.07 for insulin AUC) but not patients with diabetes mellitus (p = 0.66). Following 75 g of oral D-tag in four normal patients, plasma D-tag levels rose to a mean peak level of 3.6 mg/dl at 90 min. The administration of 75 g D-tag led to diarrhoea, nausea and/or flatulence in 100% of subjects. When D-tag was administered at lower doses ranging from 10 g to 30 g, only three of 10 patients with diabetes mellitus had gastrointestinal symptoms which were much more mild than those evoked by 75 g D-tag. These results show that oral D-tag significantly blunts the rise in plasma glucose seen after oral glucose in patients with diabetes mellitus in a dose-dependent manner without significantly affecting insulin levels. The minimal elevation of plasma D-tag levels in normal patients and the adverse gastrointestinal effects seen following larger doses of D-tag support poor absorption of this hexose and suggest that D-tag may act by attenuating glucose absorption in the intestine. D-tag may be a useful therapeutic adjunct in the management of type 2 diabetes mellitus.

Exercise training has potential benefits for patients with hyperlipidemia and/or non-insulin dependent diabetes mellitus. In nondiabetic, nonobese subjects with hypertriglyceridemia, exercise training alone increased insulin sensitivity, improved glucose tolerance, and lowered serum triglyceride and cholesterol levels. These improvements did not occur when exercise training alone was given to similar patients with impaired glucose tolerance. In severely obese (X = 125 kg) subjects without diabetes melitus, a 600 calorie diet alone decreased glucose and insulin concentrations and improved glucose tolerance but did not increase insulin sensitivity. The addition of exercise training improved insulin sensitivity. Obese, non-insulin dependent diabetes mellitus subjects on sulfonylurea therapy alone increased insulin levels but failed to improve insulin sensitivity or glucose levels. In contrast, the addition of exercise training to this medication resulted in improved insulin sensitivity and lowered glucose levels. We conclude that exercise training has major effects on lowering triglyceride levels in hyperlipidemic subjects and can potentiate the effect of diet or drug therapy on glucose metabolism in patients with non-insulin dependent diabetes mellitus.

Plasma glucose, insulin, and C peptide concentrations were determined after an oral glucose load in normal subjects and in a group of patients with non-insulin-dependent diabetes mellitus before and during a short course of treatment with chloroquine. In the control group there was a small but significant reduction in fasting blood glucose concentration but overall glucose tolerance and hormone concentrations were unaffected. In contrast, the patients with non-insulin-dependent diabetes mellitus showed a significant improvement in their glucose tolerance, which paralleled the severity of their diabetes. This response seems to reflect decreased degradation of insulin rather than increased pancreatic output. These observations suggest that treatment with chloroquine or suitable analogues may be a new approach to the management of diabetes. PMID:3103729

Metabolic diseases, especially diabetes mellitus, have become global health issues. The etiology of diabetes mellitus can be attributed to genetic and/or environmental factors. Current evidence suggests the association of gut microbiota with metabolic diseases. However, the effects of glucose-lowering agents on gut microbiota are poorly understood. Several studies revealed that these agents affect the composition and diversity of gut microbiota and consequently improve glucose metabolism and energy balance. Possible underlying mechanisms include affecting gene expression, lowering levels of inflammatory cytokines, and regulating the production of short-chain fatty acids. In addition, gut microbiota may alleviate adverse effects caused by glucose-lowering agents, and this can be especially beneficial in diabetic patients who experience severe gastrointestinal side effects and have to discontinue these agents. In conclusion, gut microbiota may provide a novel viewpoint for the treatment of patients with diabetes mellitus.

Considering traditional use of Tribulus terrestris in diabetes and proven antihyperglycemic and antihyperlipidemic effects of T terrestris in animal studies, we aimed to evaluate the efficacy of the hydroalcoholic extract of T terrestris on the serum glucose and lipid profile of women with non-insulin-dependent diabetes mellitus. Ninety-eight women with diabetes mellitus type 2 were randomly allocated to receive the T terrestris (1000 mg/d) or placebo for 3 months. The patients were evaluated in terms of the fasting blood glucose, 2-hour postprandial glucose, glycosylated hemoglobin, and lipid profile. Tribulus terrestris showed a significant blood glucose-lowering effect in diabetic women compared to placebo (P < .05). Also, the total cholesterol and low-density lipoprotein of T terrestris group was significantly reduced compared with placebo, while no significant effect was observed in the triglyceride and high-density lipoprotein levels. The study showed preliminary promising hypoglycemic effect of T terrestris in women with diabetes mellitus type 2. © The Author(s) 2016.

To evaluate the accuracy of random plasma glucose in outpatients with type 2 diabetes mellitus for assessing glycaemic control. This comparative, cross-sectional study was conducted at the chemical pathology department of PNS Shifa Hospital, Karachi, from August 2015 to March 2016, and comprised data of subjects with type 2 diabetes mellitus who reported for evaluation of glycaemic control in non-fasting state. All blood samples were analysed for random plasma glucose and glycated haemoglobin. Random plasma glucose was compared as an index test with glycated haemoglobin considering it as reference standard at a value of less than 7% for good glycaemic control. SPSS 20 was used for data analysis. Of the 222 subjects, 93(42%) had good glycaemic control. Random plasma glucose showed strong positive correlation with glycated haemoglobin (p=0.000).Area under curve for random plasma glucose as determined by plotting receiver operating characteristic curve against glycated haemoglobin value of 7% was 0.89 (95% confidence interval: 0.849-0.930). Random plasma glucose at cut-off value of 150 mg/dl was most efficient for ruling out poor glycaemic control among patients with type 2 diabetes mellitus with 90.7% sensitivity and69.9% specificity and Youden's index of 0.606. Random plasma glucose may be used to reflect glycaemic control in adults with type 2 diabetes mellitus in areas where glycated haemoglobin is not feasible.

Type 1 diabetes mellitus is a metabolic disease caused by insulin deficiency that results from destruction of β-cells in the pancreas. Based on American Diabetes Association, there are two types of type 1 diabetes mellitus: type 1A (autoimmune) and 1B (idiopathic). In this case, we are presenting a new archetype of type 1 diabetes named fulminant type 1 diabetes mellitus. This disease results from quick destruction of β-cells byanautoimmune mechanism. The manifestation of this disease consists of unspecific flu-like symptoms, abdominal symptoms, to specific hyperglycemia symptoms such as fatigue, malaise, change in mental status that are attributable to high blood glucose and ketosis. Laboratory examination reveals high blood glucose, normal glycosylated hemoglobin, ketosis or ketoacidosis, potassium depletion and elevation of liver function tests. Treatment consists of intravenous infusion followed by insulin injection for blood glucose control, followed by treatment of metabolic derangements such as acid-base and electrolyte disorder.

Gestational diabetes mellitus and pregestational diabetes mellitus constitute carbohydrate metabolism disorders, which, if not diagnosed and adequately treated, lead to serious and often life-threatening pregnancy complications. According to a recently formulated hypothesis, some diabetes-related complications, such as fetal macrosomia, may be the result of disturbances in the transplacental transport of nutrients-in particular, excessive maternal-fetal glucose transfer. Throughout pregnancy, glucose flux across the placenta is mediated by the group of facilitative glucose transporters (GLUT), the expression of which in different placental compartments is the precondition for effective glucose uptake from maternal blood and its subsequent transfer to the fetal circulation. In diabetes-complicated pregnancies, the location, expression and activity of glucose transporters are modified to an extent that results in alterations in the maternal-fetal glucose exchange, potentially leading to an excessive supply of energy substrates to the fetus. This paper reviews the literature on the expression and activity of glucose transporter proteins-GLUT-1, GLUT-3, GLUT-4, GLUT-8, GLUT-9 and GLUT-12-in the human placenta, with a special focus on diabetes-complicated pregnancy. The characteristics of transporters in conditions of maternal normoglycemia and modifications occurring in the diabetic placenta are summarized, and the factors responsible for the regulation of the expression of selected isoforms are described. Finally, the impact of alterations in the placental expression of the aforementioned members of the GLUT family on intrauterine fetal development in pregnancies complicated by diabetes mellitus is discussed.

Background Diabetes mellitus is a common metabolic disorder which shows an increasing incidence worldwide. Constant monitoring of blood glucose in diabetic patient is required which involves painful invasive techniques. Saliva is gaining acceptance as diagnostic tool for various systemic diseases which can be collected noninvasively and by individuals with limited training. Aim The aim of the present study was to analyse the possibility of using salivary glucose and glycogen content of buccal mucosal cells as a diagnostic marker in Type II Diabetes mellitus patients which can be considered as adjuvant diagnostic tool to the gold standards. Materials and Methods Sample consists of 30 study and 30 control groups. Saliva was collected by passive drool method.Intravenous blood samples were collected for glucose estimation. Exfoliated buccal mucosal cells were collected from apparently normal buccal mucosa, smeared on dry glass slide and stained with PAS. Blood and salivary glucose are estimated by Glucose Oxidase endpoint method. For Glycogen estimation, number of PAS positive cells in fifty unfolded cells was analysed. Results The results of the present study revealed a significant increase in the salivary glucose level and the number of PAS positive buccal mucosal cells in the diabetics than in the controls. The correlation between the fasting serum glucose and fasting salivary glucose and also that between fasting serum glucose and PAS positive cells was statistically significant. But the correlation between the staining intensity and fasting serum glucose was statistically insignificant. Conclusion With the results of the present study it is revealed that salivary glucose and PAS positive cells are increased in diabetics which can be considered as adjuvant diagnostic tool for Diabetes mellitus.

Women with a history of gestational diabetes mellitus are at risk of developing prediabetes. Using a cross-sectional analytic design, the factors related to prediabetes among Thai women (n = 210) with a history of gestational diabetes mellitus were investigated. The main outcomes measured were two-hour plasma glucose after taking a 75 g oral glucose tolerance test at a six week postpartum visit. Data were analyzed using descriptive statistics and Pearson's correlation. The study showed that the incidence of prediabetes among postpartum Thai women was 26.67%. Factors associated with prediabetes were: (i) being over 35 years of age; (ii) three or more pregnancies; (iii) recurrent gestational diabetes mellitus; (iv) high plasma glucose before taking a 100 g glucose tolerance test and high postprandial plasma glucose during pregnancy; and (v) being overweight or obese at six weeks' postpartum. The results showed that nursing interventions need to be implemented to reduce plasma glucose and body mass index in order to prevent or reverse prediabetes. © 2013 Wiley Publishing Asia Pty Ltd.

We performed exome-wide association studies to identify single nucleotide polymorphisms that either influence fasting plasma glucose level or blood hemoglobin A 1c content or confer susceptibility to type 2 diabetes mellitus in Japanese. Exome-wide association studies were performed with the use of Illumina Human Exome-12 DNA Analysis or Infinium Exome-24 BeadChip arrays and with 11,729 or 8635 subjects for fasting plasma glucose level or blood hemoglobin A 1c content, respectively, or with 14,023 subjects for type 2 diabetes mellitus (3573 cases, 10,450 controls). The relation of genotypes of 41,265 polymorphisms to fasting plasma glucose level or blood hemoglobin A 1c content was examined by linear regression analysis. After Bonferroni's correction, 41 and 17 polymorphisms were significantly ( P < 1.21 × 10 -6 ) associated with fasting plasma glucose level or blood hemoglobin A 1c content, respectively, with two polymorphisms (rs139421991, rs189305583) being associated with both. Examination of the relation of allele frequencies to type 2 diabetes mellitus with Fisher's exact test revealed that 87 polymorphisms were significantly ( P < 1.21 × 10 -6 ) associated with type 2 diabetes mellitus. Subsequent multivariable logistic regression analysis with adjustment for age and sex showed that four polymorphisms (rs138313632, rs76974938, rs139012426, rs147317864) were significantly ( P < 1.44 × 10 -4 ) associated with type 2 diabetes mellitus, with rs138313632 and rs139012426 also being associated with fasting plasma glucose and rs76974938 with blood hemoglobin A 1c . Five polymorphisms-rs139421991 of CAT , rs189305583 of PDCL2 , rs138313632 of RUFY1 , rs139012426 of LOC100505549 , and rs76974938 of C21orf59 -may be novel determinants of type 2 diabetes mellitus.

A prominent feature of diabetes mellitus is the inability of insulin to appropriately increase the transport of glucose into target tissues. The contributions of different glucose transport proteins to insulin resistance in rats with streptozotocin-induced diabetes was evaluated. A glucose transporter messenger RNA and its cognate protein that are exclusively expressed in muscle and adipose tissue were specifically depleted in diabetic animals, and these effects were reversed after insulin therapy; a different glucose transporter and its messenger RNA that exhibit a less restricted tissue distribution were not specifically modulated in this way. Depletion of the muscle- and adipose-specific glucose transporter species correlates with and may account for the major portion of cellular insulin resistance in diabetes in these animals.

Emerging evidence has suggested that the genetic background of gestational diabetes mellitus (GDM) was analogous to type 2 diabetes mellitus. In contrast to type 2 diabetes mellitus, the genetic studies for GDM were limited. Accordingly, the aim of the present study was to extensively explore the influence of micro-ribonucleic acid-binding single-nucleotide polymorphisms (SNPs) in type 2 diabetes mellitus candidate loci on GDM susceptibility in Chinese. A total of 839 GDM patients and 900 controls were enrolled. Six micro-ribonucleic acid-binding SNPs were selected from 30 type 2 diabetes mellitus susceptibility loci and genotyped using TaqMan allelic discrimination assays. The minor allele of three SNPs, PAX4 rs712699 (OR 1.366, 95% confidence interval 1.021-1.828, P = 0.036), KCNB1 rs1051295 (OR 1.579, 95% confidence interval 1.172-2.128, P = 0.003) and MFN2 rs1042842 (OR 1.398, 95% confidence interval 1.050-1.862, P = 0.022) were identified to significantly confer higher a risk of GDM in the additive model. The association between rs1051295 and increased fasting plasma glucose (b = 0.006, P = 0.008), 3-h oral glucose tolerance test plasma glucose (b = 0.058, P = 0.025) and homeostatic model assessment of insulin resistance (b = 0.065, P = 0.017) was also shown. Rs1042842 was correlated with higher 3-h oral glucose tolerance test plasma glucose (b = 0.056, P = 0.028). However, no significant correlation between the other included SNPs (LPIN1 rs1050800, VPS26A rs1802295 and NLRP3 rs10802502) and GDM susceptibility were observed. The present findings showed that micro-ribonucleic acid-binding SNPs in type 2 diabetes mellitus candidate loci were also associated with GDM susceptibility, which further highlighted the similar genetic basis underlying GDM and type 2 diabetes mellitus. © 2018 The Authors.

This paper examines the association between gestational diabetes mellitus and costs of care during pregnancy and 2-5 years post pregnancy. Healthcare utilization during pregnancy was measured for a sample of 658 women drawn from the Atlantic Diabetes in Pregnancy (ATLANTIC DIP) network. Healthcare utilization 2-5 years post pregnancy was assessed for a subsample of 348 women via a postal questionnaire. A vector of unit costs was applied to healthcare activity to calculate the costs of care at both time points. Differences in cost for women with gestational diabetes mellitus compared with those with normal glucose tolerance during the pregnancy were examined using univariate and multivariate regression analyses. Gestational diabetes mellitus was independently associated with an additional €817.60 during pregnancy (€1192.1 in the gestational diabetes mellitus group, €511.6 in the normal glucose tolerance group), in the form of additional delivery and neonatal care costs, and an additional €680.50 in annual healthcare costs 2-5 years after the index pregnancy (€6252.4 in the gestational diabetes mellitus group, €5434.8 in the normal glucose tolerance group). These results suggest that gestational diabetes mellitus is associated with increased costs of care during and post pregnancy. They provide indication of the associated cost that can be avoided or reduced by the screening, prevention and management of gestational diabetes mellitus in pregnancy. These estimates are useful for further studies that examine the cost and cost-effectiveness of such programmes. © 2014 The Authors. Diabetic Medicine © 2014 Diabetes UK.

To study the sensitivity and specificity of the 50-g, 1-hour gestational glucose challenge test performed 1 to 2 hours after a non-standardized home breakfast in urban Mexican women by using three different gestational diabetes mellitus diagnostic criteria. Four hundred and forty-five consecutive women of 24-28 weeks gestation were studied. The glucose challenge test was performed in the fed state and a week later a fasting 100-g, 3-hours oral glucose tolerance test was carried out in all of them. Duplicate serum glucose concentrations were determined by a glucose-oxidase method. Sensitivity and specificity were calculated using three different diagnostic criteria for gestational diabetes mellitus. The glucose challenge test performed as indicated, with a cutoff of 7.8 mmol/L, had 88-89% sensitivity and 85-87% specificity when using as diagnostic criteria those proposed by the National Diabetes Data Group and by Carpenter & Coustan; by using Sacks et al. criteria, the values were 82% and 88%, respectively. Considering only pregnant women > or = 25 years of age, the sensitivity increased to 92% with the National Diabetes Data Group criteria. Pregnant women < 25 years of age had significantly lower blood glucose values than those with age > or = 25 years during the glucose tolerance test. For the general group the sensitivity of the glucose challenge test performed 1 to 2 hours after breakfast was similar, based on the National Diabetes Data Group and the Carpenter & Coustan's diagnostic criteria for gestational diabetes mellitus. However, when pregnant women > or = 25 years of age were considered, the use of the former criteria yielded a slightly better sensitivity.

[Skin changes in diabetes mellitus].
Meurer, M; Stumvoll, M; Szeimies, R-M
2004-05-01
Diabetes mellitus is the most frequent metabolic disorder. Just under 5 million people suffer from this disease in Germany. Four types of diabetes mellitus are distinguished: type 1 diabetes, type 2 diabetes, other specific diabetes forms, and gestational diabetes. Many characteristics of diabetes mellitus including skin changes are already manifest in the "prediabetic" stage when glucose tolerance is limited so that every elevation of blood sugar levels must be considered pathological. Changes in skin due to diabetes mellitus can be categorized into four disease groups: skin infections, skin diseases found overly frequently in association with diabetes mellitus, skin alterations due to diabetic complications, and reactions to antidiabetic treatment.

To investigate the association between random measured glucose levels in middle and old age and dementia-related death. Population-based cohort study. Norwegian Counties Study (middle-aged individuals; 35-49) and Cohort of Norway participants (older individuals; 65-80). Individuals without (n=74,630) and with (n=3,095) known diabetes mellitus (N=77,725); 67,865 without and 2,341 with diabetes mellitus were included in the complete case analyses (nonmissing for all included covariates), of whom 1,580 without and 131 with diabetes mellitus died from dementia-related causes. Dementia-related death was ascertained according to the Norwegian Cause of Death Registry. Cox regression was used to assess the relationship between random glucose levels (nonfasting) in individuals without and with diabetes mellitus and dementia-related death. Education, smoking, cardiovascular disease, body mass index, cholesterol, blood pressure, and physical activity were adjusted for. Individuals without diabetes mellitus at midlife with glucose levels between 6.5 and 11.0 mmol/L had a significantly greater risk of dementia-related death than those with levels less than 5.1 mmol/L (hazard ratio=1.32, 95% confidence interval=1.04-1.67) in a fully adjusted model. A dose-response relationship (P=.02) was observed. No significant association between high glucose levels in individuals aged 65 to 80 and dementia-related death was detected. High random glucose levels measured in middle-aged but not older age persons without known diabetes mellitus were associated with greater risk of dementia-related death up to four decades later. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Gestational diabetes mellitus is associated with an increased risk of type 2 diabetes mellitus and hypertension. Additionally, gestational dysglycemia has been associated with an increased risk of type 2 diabetes mellitus but not yet associated with hypertension subsequent to pregnancy in long-term follow-up. Therefore, we set out to examine this relationship as well as the role of race/ethnicity in modifying this relationship. We analyzed a prospective observational cohort followed between 1998 and 2007. There were 17 655 women with self-reported race/ethnicity and full-term, live births. A 1-hour 50 g oral glucose-load test and a 3-hour 100 g oral glucose-tolerance test enabled third trimester stratification of women into 1 of 4 glucose-tolerance groups: (1) normal (n=15 056); (2) abnormal glucose-load test (n=1558); (3) abnormal glucose-load and -tolerance tests (n=520); and (4) gestational diabetes mellitus (n=521). Women were then followed for a mean±standard deviation of 4.1±2.9 years after delivery for the development of hypertension. Although gestational diabetes mellitus was associated with an increased risk of hypertension after pregnancy (odds ratio [95% confidence interval]: 1.58 [1.02, 2.45]; P=0.04), dysglycemia defined by an abnormal glucose-load test predicted hypertension only among black women (4.52 [1.24, 16.52]; P=0.02). The risk of hypertension after pregnancy among dysglycemia groups not meeting criteria for gestational diabetes mellitus varied based on the race/ethnicity of the population. Further research on the implications of the intersection of race/ethnicity and gestational dysglycemia on subsequent hypertension is warranted. © 2015 American Heart Association, Inc.

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.

There is limited information on the association between metabolic syndrome components including body mass index (BMI) and type 2 diabetes mellitus in elderly Chinese population. Therefore, we investigated whether components of metabolic syndrome are associated with type 2 diabetes mellitus in elderly. A total of 479 hospitalized patients (aged 65-95 years) with recently diagnosed type 2 diabetes mellitus were studied retrospectively in a cross-sectional study and compared with 183 subjects with prediabetes and 62 subjects without glucose metabolism abnormalities. BMI (24.69±3.59 versus 23.92±3.08 and 23.56±3.25 kg/m 2 ), blood pressure, cholesterol, triglyceride, liver enzymes and prevalence of fatty liver were higher in patients with type 2 diabetes mellitus as compared with elderly subjects with prediabetes or normal glucose metabolism separately (all P <0.05). Multivariable regression analysis showed that BMI was associated positively with insulin resistance and inversely with insulin sensitivity in type 2 diabetes mellitus group (all P <0.05). Higher BMI was associated with increased insulin resistance and decreased insulin sensitivity in elderly Asian population with type 2 diabetes mellitus.

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 < .05). Significantly increased GLUT-1 expression was observed only in placental specimens from patients with PGDM (p < .05). No statistically significant differences in GLUT expression were found between GDMG1 patients and healthy controls. The results of the study confirmed the presence of GLUT-1, GLUT-4 and GLUT-9 proteins in the trophoblast from both, uncomplicated and 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 find out if commercial capsules with dried nopal (prickle-pear cactus, Opuntia ficus indica may have a role in the management of diabetes mellitus, three experiments were performed: 30 capsules where given in fasting condition to 10 diabetic subjects and serum glucose was measured through out 3 hours; a control test was performed with 30 placebo capsules. OGTT with previous intake of 30 nopal or placebo capsules was performed in ten healthy individuals. In a crossover and single blinded study 14 diabetic patients withdrew the oral hypoglycemic treatment and received 10 nopal or placebo capsules t.i.d. during one week; serum glucose, cholesterol and tryglycerides levels were measured before and after each one-week period. Five healthy subjects were also studied in the same fashion. Opuntia capsules did not show acute hypoglycemic effect and did not influence OGTT. In diabetic patients serum glucose, cholesterol and tryglycerides levels did not change with Opuntia, but they increased with placebo (P < 0.01 glucose and cholesterol, P = NS triglycerides). In healthy individuals glycemia did not change with nopal, while cholesterol and triglycerides decreased (P < 0.01 vs. placebo). The intake of 30 Opuntia capsules daily in patients with diabetes mellitus had a discrete beneficial effect on glucose and cholesterol. However this dose is unpractical and at present it is not recommended in the management of diabetes mellitus.

In 2010, the American Diabetes Association (ADA) proposed that individuals with fasting glucose level of 100-125 mg/dL (5.6-6.9 mmol/L) or glucose level of 140-199 mg/dL (7.8-11.0 mmol/L) 2 hours after a 75-g oral glucose tolerance test or hemoglobin A(1c) 5.7%-6.4% be classified as prediabetic, indicating increased risk for the emergence of diabetes mellitus. At the same time, the ADA formulated guidelines for the use of metformin for the treatment of prediabetes. To determine the prevalence of prediabetes in a cohort of psychiatrically ill adults receiving antipsychotics and to compare the clinical and metabolic features of prediabetic patients with those of patients with normal glucose tolerance and those with diabetes mellitus. The 2010 ADA criteria were applied to a large, consecutive, single-site European cohort of 783 adult psychiatric inpatients (mean age: 37.6 years) without a history of diabetes who were receiving antipsychotics. All patients in this cross-sectional study underwent measurement of body mass index (BMI), waist circumference, oral glucose tolerance test, and fasting insulin and lipids from November 2003 through July 2007. 413 patients (52.8%) had normal glucose tolerance, 290 (37.0%) had prediabetes, and 80 (10.2%) had diabetes mellitus. The fasting glucose and/or hemoglobin A(1c) criteria were met by 89.7% of prediabetic patients. A statistically significant intergroup gradient from normal glucose tolerance to prediabetes and from prediabetes to diabetes mellitus was observed for waist circumference, triglycerides, fasting insulin levels, and frequency of metabolic syndrome (P = .02 to P < .0001). Only 19/290 prediabetic patients (6.6%) met the 2010 ADA criteria for treatment with metformin. Prediabetes is highly prevalent in adults treated with antipsychotic drugs and correlates with markers of increased intraabdominal adiposity, enhanced lipolysis, and insulin resistance. Criteria for using metformin to prevent the emergence of diabetes mellitus may need to be revised for this population. © Copyright 2012 Physicians Postgraduate Press, Inc.

While evaluating the toxicity of the tuberous root extracts of Hemidesmus indicus, a traditional medicinal plant, the glucose lowering property of the root was observed by the investigators. Therefore, it was thought of interest to isolate the anti-hyperglycemic principle from the root and determine its utility to develop an anti-diabetes mellitus medicine. The active principle was isolated from H. indicus root extract by anti-hyperglycemic activity guided chromatographic techniques. Glucose tolerance test in rats was used to evaluate the anti-hyperglycenic property. Anti-diabetes mellitus property was evaluated in alloxan-induced diabetic rats as well as streptozotocin-induced (type-2 model) diabetic rats. The active principle was isolated and identified with spectral data as β-amyrin palmitate. Although it is a known compound, its presence in H. indicus is not known previously. It was observed for the first time that β-amyrin palmitate has remarkable anti-hyperglycemic activity in orally glucose loaded rats. Further, interestingly, it exhibited excellent anti-diabetes mellitus activity in both alloxan-diabetic and streptozotocin-diabetic rats at a very low concentration (50µg/kg body weight). One of the mechanisms of action of β-amyrin palmitate appears to be blocking the entry of glucose from the intestine. β-Amyrin palmitate is very promising to develop a medicine for diabetes for combination therapy and/or mono-therapy.

Oral glucose tolerance test (OGTT) is a sensitive and reliable test for diabetes mellitus and impaired glucose tolerance (IGT). However, poor patient tolerance of glucose solutions is common. We aim to compare the diagnostic value of an ice cream test with a standard OGTT. A total of 104 healthy adults were randomly assigned to either 75-g OGTT or ice cream, followed by a crossover to the other test. Most patients were females (71%). Mean age was 37 ± 12 years, and body mass index was 24.2 ± 3.9kg/m 2 . Diabetes mellitus and IGT, as diagnosed by 75-g OGTT, were 4.8% and 6.7%, respectively. The 2-hour plasma glucose levels were 110 ± 55.5mg/dL with 75-g glucose and 97.52 ± 40.7mg/dL with ice cream. The correlation coefficient of 2-hour plasma glucose for the 2 tests was 0.82 (95% CI: 0.75-0.87; P < 0.001). Discordant diagnostic results, based on 2-hour plasma glucose levels, were 9.61%. By using a combination of fasting plasma glucose and 2-hour plasma glucose values, the ice cream test would have missed 5.76% of those at high risk for diabetes mellitus (impaired fasting glucose and IGT) or diabetes. An ice cream test may serve as an alternative to a 75-g OGTT. Before applying this test in clinical practice, it needs to be validated in a larger population.

The usefulness of urine tests for glucose was compared with that of blood sugar determinations in detecting diabetes mellitus in 2000 medical outpatients. Eighty-five patients proved to be diabetic, but 33 of these had no glycosuria on their first visit and would not have been detected by laboratory tests had the blood glucose levels not been measured. Exactly one-half of the new diabetics discovered would have been missed (15 of 30) had only urine tests been performed. The new diabetics who were aglycosuric at their initial examination had a mild form of the disease, were predominantly elderly, and were controlled, in nearly every case, by diet alone. Most of these patients had evidence of an elevated renal threshold for glucose. These results indicate that there is a large group of patients with mild, asymptomatic, diabetes mellitus who remain undetected unless blood tests are employed routinely. Because they have little or no glycosuria these patients do not have polydipsia, polyphagia, polyuria, or loss of weight. Automation in the medical laboratory has made routine blood tests for glucose feasible and rewarding in detecting diabetes mellitus. PMID:20327667

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.

Patients with diabetes mellitus need information about the effectiveness of innovations in insulin delivery and glucose monitoring. To review how intensive insulin therapy (multiple daily injections [MDI] vs. rapid-acting analogue-based continuous subcutaneous insulin infusion [CSII]) or method of monitoring (self-monitoring of blood glucose [SMBG] vs. real-time continuous glucose monitoring [rt-CGM]) affects outcomes in types 1 and 2 diabetes mellitus. MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials through February 2012 without language restrictions. 33 randomized, controlled trials in children or adults that compared CSII with MDI (n=19), rt-CGM with SMBG (n=10), or sensor-augmented insulin pump use with MDI and SMBG (n=4). 2 reviewers independently evaluated studies for eligibility and quality and serially abstracted data. In randomized, controlled trials, MDI and CSII showed similar effects on hemoglobin A1c (HbA1c) levels and severe hypoglycemia in children or adults with type 1 diabetes mellitus and adults with type 2 diabetes mellitus. In adults with type 1 diabetes mellitus, HbA1c levels decreased more with CSII than with MDI, but 1 study heavily influenced these results. Compared with SMBG, rt-CGM achieved a lower HbA1c level (between-group difference of change, 0.26% [95% CI, 0.33% to 0.19%]) without any difference in severe hypoglycemia. Sensor-augmented insulin pump use decreased HbA1c levels more than MDI and SMBG did in persons with type 1 diabetes mellitus (between-group difference of change, 0.68% [CI, 0.81% to 0.54%]). Little evidence was available on other outcomes. Many studies were small, of short duration, and limited to white persons with type 1 diabetes mellitus. Continuous subcutaneous insulin infusion and MDI have similar effects on glycemic control and hypoglycemia, except CSII has a favorable effect on glycemic control in adults with type 1 diabetes mellitus. For glycemic control, rt-CGM is superior to SMBG and sensor-augmented insulin pumps are superior to MDI and SMBG without increasing the risk for hypoglycemia.

Nonenzymatic glycation of peptides and proteins by d-glucose has important implications in the pathogenesis of diabetes mellitus, particularly in the development of diabetic complications. In this work, we report the first proteomics-based characterization of nonenzymatically glycated proteins in human plasma and erythrocyte membranes from individuals with normal glucose tolerance, impaired glucose tolerance, and type 2 diabetes mellitus. Phenylboronate affinity chromatography was used to enrich glycated proteins and glycated tryptic peptides from both human plasma and erythrocyte membranes. The enriched peptides were subsequently analyzed by liquid chromatography coupled with electron transfer dissociation-tandem mass spectrometry, resulting in the confident identification of 76 and 31 proteins from human plasma and erythrocyte membranes, respectively. Although most of the glycated proteins could be identified in samples from individuals with normal glucose tolerance, slightly higher numbers of glycated proteins and more glycation sites were identified in samples from individuals with impaired glucose tolerance and type 2 diabetes mellitus.

To review the incident status of childhood type 1 diabetes mellitus hospitalized in the Children's Hospital of Zhejiang University School of Medicine from 1999 to 2009 and to explore the clinical value of IL-10 in diabetic ketoacidosis. The clinical data of 263 children with type 1 diabetes mellitus hospitalized in the Children's Hospital of Zhejiang University School of Medicine from January 1999 to February 2009 were retrospectively reviewed. Serum lipid levels were measured in 48 children with type 1 diabetes mellitus and in 24 healthy children. The diabetic children were classified into two subgroups, with or without ketoacidosis. Serum lipid and cytokines levels were compared. Childhood type 1 diabetes mellitus was common in females (56.3%). The peak incident age of the disease was between 6 and 11.9 years. Diabetic ketoacidosis was as the presenting symptom for the first visit in 86 cases (32.7%). The levels of serum lipid, blood glucose and HbA1c in diabetic children with ketoacidosis were significantly higher than those without ketoacidosis (P<0.05). Logistic analysis demonstrated that the increased levels of blood glucose, serum lipid and HbA1c were risk factors for diabetic ketoacidosis. The level of serum IL-10 in diabetic children with ketoacidosis was significantly higher than that in patients without ketoacidosis (P<0.01), while there were no differences in serum levels IL-2, IL4, IL-6, TNF-α and IFN-γ between them. Serum levels IL-2, IL-4, IL-6, IL-10, TNF-α and IFN-γ in diabetic children were significantly higher than those in healthy children (P<0.01). Ketoacidosis is a common acute complication of type 1 diabetes mellitus. The disorders of glucose and lipid metabolism are the risk factors for ketoacidosis in diabetic children. IL-10 may be a sensitive index of diabetic ketoacidosis in children with type 1 diabetes mellitus.

To evaluate the effect of a high insoluble-fiber (HF) diet containing 12% cellulose in dry matter and a low insoluble-fiber (LF) diet on control of glycemia in dogs with naturally acquired insulin-dependent diabetes mellitus. Prospective randomized crossover controlled trial. 11 dogs with naturally acquired diabetes mellitus. Dogs were fed HF and LF diets for 8 months each in 1 of 2 randomly assigned diet sequences. Caloric intake and insulin treatment were adjusted as needed to maintain stable body weight and control of glycemia, respectively. After a 2-month adaptation period, control of glycemia was evaluated every 6 weeks for 6 months. Variables assessed included serum glucose concentration measured during the preprandial state, blood glycosylated hemoglobin concentration, serum glucose concentration measured every 2 hours for 24 hours beginning at the time of the morning insulin injection, 24-hour mean serum glucose concentration, mean serum glucose concentration fluctuation from the 24-hour mean serum glucose concentration, and 24-hour urinary excretion of glucose. Significant differences in mean daily caloric intake, body weight, or daily insulin dosage among dogs fed HF and LF diets were not found. Mean preprandial serum glucose concentration, most postprandial serum glucose concentrations, 24-hour mean serum glucose concentration, and 24-hour urinary excretion of glucose were significantly lower in dogs fed the HF diet, compared with the LF diet. Results of this study support feeding of commercially available insoluble fiber diets to dogs with naturally acquired diabetes mellitus.

To report a case of an adverse drug reaction (ADR) in a patient with type 2 diabetes mellitus taking prickly pear cactus (PPC), glipizide, and metformin. A 58-year-old Mexican male with type 2 diabetes mellitus being treated with metformin 1000 mg twice daily and extended-release glipizide 10 mg daily was referred to the pharmacist for medication education. He denied taking herbal supplements or experiencing hypoglycemia. Two hemoglobin A(1c) values (6.8% and 6.7%) obtained over the past year demonstrated glycemic control, which was supported by his reported fasting blood glucose readings of 113-132 mg/dL. One month later, the patient reported 4 hypoglycemic events with blood glucose readings of 49-68 mg/dL, which resulted in discontinuation of glipizide. One month later, the patient denied any further hypoglycemia. During medication reconciliation he reported consuming crude PPC pads daily for 2 months for glucose control. Literature suggests that PPC has an effect on lowering blood glucose levels in patients with type 2 diabetes mellitus, although few identified data describe ADRs from combining PPC with other agents used in treating type 2 diabetes mellitus. A literature search of MEDLINE (through December 2009) using the search terms diabetes mellitus, prickly pear cactus, nopal, opuntia, metformin, glipizide, glyburide, glimepiride, and sulfonylurea revealed no case reports of the described ADR. One case report describing the blood glucose-lowering effect of PPC in a patient concurrently taking oral antihyperglycemics documented an episode of hypoglycemia, although the Naranjo probability scale was not applied. One patient survey discovered the most common drug-herbal interaction in the given population to be between PPC and antihyperglycemic agents, resulting in hypoglycemia. In our case, use of the Naranjo probability scale suggests the ADR to be probable. The mechanism may be due to the additive glucose lowering of the 3 agents consumed concurrently by the patient. Patients with type 2 diabetes mellitus should be routinely counseled about the use of herbal products to minimize the risk of ADRs.

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.

Offspring of type 2 diabetics have an increased risk of dyslipidemia, glucose intolerance and obesity. The aim of this study was to assess the lipid levels in the offspring of diabetics with normal glucose tolerance and normal body weight. Normal weight offspring of patients with type 2 diabetes mellitus (DM) who had normal glucose tolerance, and healthy gender matched controls of comparable age without a family history of diabetes mellitus, were the subjects of this study. Lipid profiles were determined in cases and controls. The study included 114 subjects (64 males and 50 females) in each group, aged (mean ± SD) 24.0 ± 7.9 in cases and 24.1 ± 8.0 years in controls. The body mass index (BMI) was 20.8 ± 3.0 and 20.2 ± 3.1 kg/m2 in cases and controls, respectively. Serum total cholesterol, triglycerides, plasma glucose, fasting insulin, C-peptide and proinsulin levels were comparable in cases and controls. Serum high density lipoprotein (HDL) cholesterol was lower (p <0.001), whilst the serum triglyceride/HDL ratio, low density lipoprotein (LDL) cholesterol and area under the curve for insulin and proinsulin during an oral glucose tolerance test were higher in cases compared to controls. HDL cholesterol showed no significant correlation with plasma glucose, insulin or proinsulin. Plasma HDL cholesterol is low among normal weight, normoglycemic offspring of subjects with type 2 diabetes mellitus. The implications of this finding are not apparent.

The absence, destruction, or loss of β-cells of pancreas results in type 1 diabetes (insulin-dependent diabetes mellitus [IDDM]). Presently, diagnosis and periodic monitoring of diabetes is achieved by evaluating blood glucose levels as it is relatively invasive and dreaded by children. In the light of this, present study was planned to compare salivary glucose values with blood glucose values and the biochemical characteristics of saliva in IDDM children were evaluated and obtained results were compared with the salivary parameters of normal children. Thirty IDDM children and 30 healthy children were selected for the study. Fasting blood sample and unstimulated salivary sample were collected from all the subjects and were subjected for analysis. A weak positive correlation was noticed between fasting blood glucose and salivary glucose values in IDDM children. But a mean average of salivary glucose was high in IDDM children when compared with healthy children. The biochemical parameters like acid phosphatase, total protein count, and α-amylase were increased, whereas salivary urea did not show significant variation between the groups. With presently used diagnostic armamentarium, estimation of salivary glucose cannot replace the standard method of estimation of glucose in diabetic mellitus children. The established relationship was very weak with many variations.

The prevalence of diabetes mellitus and factors associated with it, nowadays, are increasing in alarming rates among different occupational groups. Of these occupational groups are Police officers that, often, are exposed to unique life styles and stressful situations which may lead to diabetes mellitus and other cardiovascular diseases. Due to this reason, the present study was conducted to assess the prevalence and factors associated with diabetes mellitus and impaired fasting glucose level among members of federal police commission residing in Addis Ababa, Ethiopia. A cross-sectional study design was conducted from April to May 2015. Multistage and systematic random sampling techniques were employed to select the study participants. The study population was federal police commission members living in Addis Ababa and served for at least a year. The data were collected using structured questionnaire, physical examinations and blood samples, based on the WHO stepwise approach. Data were entered in to SPSS version 20.0 and descriptive statistics and logistics regression were used for analysis. Out of the 1003 eligible subjects, 936 (93.3%) police officers have participated in this study. The prevalence of overall impaired glucose homeostasis (IGH) was 120 (13%) of which 47 (5%) were diabetes and 73 (8%) were impaired fasting glucose. Whereas police rank, history of first degree relative who suffered from diabetes, hypertension and waist hip ratio showed a statistical significance with prevalence of diabetes mellitus, age, family history, hypertension, BMI and waist hip ratio were found to be associated with impaired fasting glucose. The study identified a high prevalence of IGH among the police officers. A priority should be given on preventive strategies of diabetes mellitus, as that of communicable diseases, by Federal Police Commission Health Service Directorate, Federal Ministry of Health and other concerned partners.

Application of Semipermeable Membranes in Glucose Biosensing
Kulkarni, Tanmay; Slaughter, Gymama
2016-01-01
Glucose biosensors have received significant attention in recent years due to the escalating mortality rate of diabetes mellitus. Although there is currently no cure for diabetes mellitus, individuals living with diabetes can lead a normal life by maintaining tight control of their blood glucose levels using glucose biosensors (e.g., glucometers). Current research in the field is focused on the optimization and improvement in the performance of glucose biosensors by employing a variety of glucose selective enzymes, mediators and semipermeable membranes to improve the electron transfer between the active center of the enzyme and the electrode substrate. Herein, we summarize the different semipermeable membranes used in the fabrication of the glucose biosensor, that result in improved biosensor sensitivity, selectivity, dynamic range, response time and stability.

Elevated concentrations of liver enzymes have been associated with an increased risk of developing type 2 diabetes mellitus. However, it remains unclear to which specific aspects of diurnal glucose metabolism these associate most. We aimed to investigate the associations between liver enzyme concentrations and 24 h-glucose trajectories in individuals without diabetes mellitus from three independent cohorts. This cross-sectional study included 436 participants without diabetes mellitus from the Active and Healthy Aging Study, the Switchbox Study, and the Growing Old Together Study. Fasting blood samples were drawn to measure gamma-glutamyltransferase (GGT), alanine transaminase, and aspartate transaminase. Measures of glycemia (e.g., nocturnal and diurnal mean glucose levels) and glycemic variability (e.g., mean amplitude of glucose excursions) were derived from continuous glucose monitoring. Analyses were performed separately for the three cohorts; derived estimates were additionally meta-analyzed. After meta-analyses of the three cohorts, elevated liver enzyme concentrations, and specifically elevated GGT concentrations, were associated with higher glycemia. More specific, participants in the highest GGT tertile (GGT ≥37.9 U/L) had a 0.39 mmol/L (95% confidence interval: 0.23, 0.56) higher mean nocturnal glucose (3:00 to 6:00 a.m.) and a 0.23 mmol/L (0.10, 0.36) higher diurnal glucose (6:00 to 0:00 a.m.) than participants in the lowest GGT tertile (GGT <21.23 U/L). However, elevated liver enzyme concentrations were not associated with a higher glycemic variability. Though elevated liver enzyme concentrations did not associate with higher glycemic variability in participants without diabetes mellitus, specifically, elevated GGT concentrations associated with higher glycemia.

The prevalence of diabetes is rapidly rising all over the globe at an alarming rate. In India, more than 61.3 million people have been presently diagnosed with type 2 diabetes mellitus. It is possible to control the circulating blood glucose levels by reducing life style risk factors through physical activities comprising of muscle stretches, aerobic training, resistance exercises (REs), yoga, etc. The aim of this study is to identify and compare the immediate effect of passive static stretching (PSS) versus RE on blood glucose level in individuals with type 2 diabetes mellitus. The present study included 51 participants between the age of 40-65 years with type 2 diabetes mellitus, to study the immediate effect of 60-min PSS (n=25) and 60-min RE (n=26). The outcome measure was blood glucose level which was checked by glucometer (free-style neo). Blood sugar was assessed at 3 points of time that included fasting blood sugar level, 2 hr after the meal and immediately after the exercise regimen. Results of this study showed significant reduction in blood glucose level in subjects according to glucometer with PSS ( P =0.000) and RE ( P =0.00). However, both groups demonstrated equal effect in terms of lowering blood sugar level immediately after the exercise. The conclusion is both PSS and RE are effective in reducing postprandial blood glucose level in type 2 diabetes mellitus and must be prescribed for the patients who demonstrate difficulty in controlling post prandial spike.

Oxidative stress has a key role in the pathogenesis of diabetes. Propolis and its constituents have a wide range of medicinal properties against oxidative stress. In the present study, we evaluated the anti-oxidant effects of ethanolic extracts of propolis on kidneys in diabetes mellitus rats. A total of 40 male Wistar rats were randomly divided into the following five groups: control, diabetes mellitus, diabetes mellitus with vehicle treatment, diabetes mellitus with propolis treatment (100 mg/kg) and diabetes mellitus with propolis treatment (200 mg/kg). Diabetes mellitus in rats was induced by intraperitoneal injection of streptozotocin (60 mg/kg). Diabetic groups were treated with vehicle or ethanolic extracts of Iranian propolis for 6 weeks. Serum concentration of malondialdehyde, superoxide dismutase and glutathione peroxidase were measured. The results showed that Iranian propolis significantly inhibited bodyweight loss in diabetes mellitus rats. The propolis extracts significantly reduced serum glucose levels and kidney weight in diabetes mellitus rats (P < 0.001). Furthermore, propolis extracts significantly reduced the malondialdehyde content, and increased the activity of superoxide dismutase and glutathione peroxidase (P < 0.001) along with the total anti-oxidant activity in the kidney tissue of diabetes mellitus rats. In the kidneys of the diabetes mellitus and vehicle group, the glomerular basement membrane thickness and glomerular area were significantly increased. Treatment of diabetes mellitus rats with the propolis extract significantly reduced the glomerular basement membrane thickness and glomerular area. The present study results showed that the Iranian propolis extract could enhance the anti-oxidant levels and histopathological changes in the kidneys of rats. The final results showed that most of the favorable effects of propolis are mediated by a reduction of blood glucose levels in diabetic animals. © 2015 The Authors.

Diabetes mellitus in pregnancy has profound implications for the baby and mother and thus active screening for this is desirable. Fifty grams oral glucose challenge test was administered after obtaining consent to 222 women in good health with singleton pregnancies without diabetes mellitus at 24 to 28 weeks gestation after an overnight fast. Venous blood sample was obtained before and 1 hour after the glucose load. A diagnostic 3-hour 100 g oral glucose tolerance test was subsequently performed in all. Two hundred and ten women had a normal response to oral glucose tolerance test i.e. venous plasma glucose below these cut-off levels: fasting 95 mg/dl (5.3 mmol/l), 1 hour 180 mg/dl (10.0 mmol/l), 2 hours 155 mg/dl (8.6 mmol/l) and 3 hours 140 mg/dl (7.8 mmol/l), while 12 were found to have gestational diabetes mellitus and were subsequently excluded from the study. They were appropriately managed. The mean maternal age was 30.9 ± 4.1 years (range 19 to 45 years) and the mean parity was 1.2 ± 1.1 (range 0 to 5). The mean fasting plasma glucose was 74.5 ± 11.5 mg/dl (range 42 to 117 mg/dl), while the mean plasma glucose 1 hour after 50 g glucose challenge test was 115.3 ± 19.1 mg/dl (range 56 to 180 mg/dl). The mean fasting plasma glucose in normal pregnant Nigerians was 74.5 ± 11.5 mg/dl (range 42 to 117 mg/dl). There is a need to re-appraise and possibly review downwards the World Health Organization fasting plasma glucose diagnostic criteria in pregnant Nigerians for better detection of gestational diabetes mellitus. Pregnant women with venous plasma glucose greater than 153.5 mg/dl (8.5 mmol/l) 1 hour after 50 g glucose challenge test are strongly recommended for diagnostic test of gestational diabetes mellitus.

Resistin role in development of gestational diabetes mellitus.
Siddiqui, Khalid; George, Teena P
2017-07-01
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.

It has been known that chronic liver treatments interfere with blood glucose metabolism. It was recognized that diabetes mellitus among chronic hepatitis C was greater in other types of chronic liver diseases. Hepatitis C directly promotes insulin resistance through the proteosomal degradation of insulin resistance substrate. It suppressed hepatocyte glucose uptake through down-regulation of surface expression of glucose transporter. Long-term exposure to cytokine over expression seems to be cytotoxic to both beta cells of the pancreas and to hepatocytes. Elevated tumor necrosis factor-a, or its neutralization, increased insulin sensitivity. Interferon-a may also elevate the serum level of interleukin-1 which is cytotoxic to pancreatic islet cells. Both diabetes mellitus and resistance to interferon-a therapy are abnormally mediated by over-expression of suppressor of cytokine signaling-1 in hepatocytes of chronic hepatitis C patients. These data suggest that interferon-a therapy should be administered with caution in patients showing any predisposition to Diabetes mellitus. Anti inflammatory therapy is critically recommended as a protector against disease development due to cytokine mediated Diabetes mellitus during hepatitis C therapy, since inflammation seems to be a main candidate to interferon suspected diabetogenesis.

To determine an influence of alpha-lipoic acid to reduction of body weight and regulation of total cholesterol concentration, triglycerides and glucose serum levels in obese patients with diabetes mellitus type 2. A prospective study includes two groups of obese patients with diabetes mellitus and signs of peripheral polyneuropathia: examined group (30 patients; 15 females and 15 males), and control group (30 patients; 12 females and 18 males). All were treated with metformin (850-1700 mg/day). Examined patients were additionally treated with alpha-lipoic acid 600 mg/day during 20 weeks. Body mass index and concentrations of total cholesterol, triglycerides and glucose in serum were compared before and after the treatment. The group treated with 600 mg alpha-lipoic acid lost significantly more weight, and had lower triglyceride level than the control group. There were no significant differences in total cholesterol and glucose serum levels between the groups. Alpha-lipoic acid of 600 mg/day treatment have influenced weight and triglycerides loss in obese patients with diabetes mellitus type 2. It should be considered as an important additive therapy in obese patients with diabetes mellitus type 2. Copyright© by the Medical Assotiation of Zenica-Doboj Canton.

Obestatin and ghrelin are peptides encoded by the preproghrelin gene. Obestatin inhibits food intake, in addition to regulation of glucose and lipid metabolism. Here, we test the ability of obestatin at improving metabolic control and liver function in type 2 diabetic animals (type 2 diabetes mellitus). The effects of chronic obestatin treatment of mice with experimentally induced type 2 diabetes mellitus on serum levels of glucose and lipids, and insulin sensitivity are characterized. In addition, alterations of hepatic lipid and glycogen contents are evaluated. Obestatin reduced body weight and decreased serum glucose, fructosamine, and β-hydroxybutyrate levels, as well as total and low-density lipoprotein fractions of cholesterol. In addition, obestatin increased high-density lipoproteins cholesterol levels and enhanced insulin sensitivity in mice with type 2 diabetes mellitus. Moreover, obestatin diminished liver mass, hepatic triglycerides and cholesterol contents, while glycogen content was higher in livers of healthy and mice with type 2 diabetes mellitus treated with obestatin. These changes were accompanied by reduction of increased alanine aminotransferase, aspartate aminotransferase, and gamma glutamyl transpeptidase in T2DM mice with type 2 diabetes mellitus. Obestatin increased adiponectin levels and reduced leptin concentration. Obestatin influenced the expression of genes involved in lipid and carbohydrate metabolism by increasing Fabp5 and decreasing G6pc, Pepck, Fgf21 mRNA in the liver. Obestatin increased both, AKT and AMPK phosphorylation, and sirtuin 1 (SIRT1) protein levels as well as mRNA expression in the liver. Obestatin improves metabolic abnormalities in type 2 diabetes mellitus, restores hepatic lipid contents and decreases hepatic enzymes. Therefore, obestatin could potentially have a therapeutic relevance in treating of insulin resistance and metabolic dysfunctions in type 2 diabetes mellitus.

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

Optimizing postpartum care for the patient with gestational diabetes mellitus.
Martinez, Noelle G; Niznik, Charlotte M; Yee, Lynn M
2017-09-01
Gestational diabetes mellitus poses well-established risks to both the mother and infant. As >50% of women with gestational diabetes mellitus will develop type 2 diabetes mellitus in their lifetime, performing postpartum oral glucose tolerance testing is paramount to initiation of appropriate lifestyle interventions and pharmacologic therapy. Nonetheless, test completion among women with gestational diabetes mellitus is estimated to be <50%, with particularly low rates in Latina patients, as well as patients with public insurance, low education levels, and low health literacy. Data suggest our current health services infrastructure loses patients in the postpartum gap between pregnancy-focused care and primary care. Previous studies have suggested strategies to promote oral glucose tolerance testing completion to identify type 2 diabetes mellitus. Based on existing evidence, we propose best practices for the postpartum care of women with gestational diabetes mellitus: (1) enhanced patient support for identifying long-term health care providers, (2) patient-centered medical home utilization when possible, (3) patient and provider test reminders, and (4) formalized obstetrician-primary care provider hand offs using the Situation Background Assessment Recommendation (SBAR) mnemonic. These strategies deserve future investigation to solidify a multilevel approach for identifying and preventing the continuum of diabetes. Copyright © 2017 Elsevier Inc. All rights reserved.

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

Barengo, Noël Christopher; Tamayo, Diana Carolina; Tono, Teresa; Tuomilehto, Jaakko
2017-02-01
(i) To develop a diabetes mellitus risk score model for the Colombian population (ColDRISC); and (ii) to evaluate the accuracy of the ColDRISC unknown Type 2 diabetes mellitus METHODS: Cross-sectional screening study of the 18-74 years-old population of a health-care insurance company (n=2060) in northern Colombia. Lifestyle habits and risk factors for diabetes mellitus were assessed by an interview using a questionnaire consisting of information regarding sociodemographic factors, history of diabetes mellitus, tobacco consumption, hypertension, nutritional and physical activity habits. Anthropometric measurements and an oral glucose tolerance test were taken. The sensitivity and the specificity, receiver-operating characteristic (ROC) curves, were calculated for the ColDRISC and FINDRISC. The area under the ROC curve for unknown Type 2 diabetes mellitus was 0.74 (95% CI: 0.70-0.79) for the ColDRISC and 0.73 for the FINDRISC (95% confidence intervals [CI] 0.69-0.78). Using the risk score cutoff value of 4 in the ColDRISC to detect Type 2 diabetes mellitus resulted in a sensitivity of 73% and specificity of 67%. The characteristics of the ColDRISC show that it can be used as a simple, safe, and inexpensive test to identify people at high risk for Type 2 diabetes mellitus in Colombia.

2018-03-01
The purpose of this article is to simulate the glucose dynamic and the insulin kinetic of diabetic patient. The model used in this research is a non-linear Minimal Bergman model. Optimal control theory is then applied to formulate the problem in order to determine the optimal dose of insulin in the treatment of diabetes mellitus such that the glucose level is in the normal range for some specific time range. The optimization problem is solved using dynamic programming. The result shows that dynamic programming is quite reliable to represent the interaction between glucose and insulin levels in diabetes mellitus patient.

Increasing prevalence of diabetes mellitus in a developing country and its related factors.
Animaw, Worku; Seyoum, Yeshaneh
2017-01-01
All countries, irrespective of their developmental stage, face an increasing burden of non-communicable diseases including diabetes mellitus. There is substantial evidence of the existence of the gap in the level of diabetes mellitus and its complications prevention and control measures in developing countries. This study aimed to assess the prevalence of diabetes mellitus in urban and rural dwellers in a low-income country from both younger and older population and to identify factors related. This is a community based comparative cross-sectional study conducted in a low-income country, Ethiopia. The sample size was determined by EPI-Info for two populations; the WHO's STEP-wise approach for non-communicable diseases surveillance in developing countries was employed for sampling, study variable selection and data collection procedures. Fasting blood glucose levels were measured by finger pricking after overnight fasting. Data entry was done by EPI-data computer program version 3.1 and then processed by SPSS version 20. Bivariate and multivariate logistic regression tests were used to assess the associations between diabetes status of individuals and its potential predictor variables. P-value < 0.05 was considered as statistically significant level. The study was conducted on 1405 individuals with age range of 18-97 years old. The mean fasting blood glucose level for study participants was 91.16mg/dl; while it was 94.73mg/dl for urban and 87.71mg/dl for rural dwellers. The prevalence of diabetes mellitus was 3.3%; while it was 2.0% for rural and (4.6%) for urban dwellers. Both the mean blood glucose level and the prevalence of diabetes mellitus were significantly higher for urban residents than rural. More than three-fourths of diabetic cases were newly diagnosed by this study. Urban dwellers, centrally obese, overweight, and hypertensive individuals have higher odds of getting diabetes mellitus. High prevalence of diabetes mellitus involving both old and young population was documented. Most diabetic cases were suddenly diagnosed during this survey. The problem is noticeably alarming, attention should be given to the control and prevention of diabetes mellitus and related complications.

To determine the effects of protein alone (independent of fat and carbohydrate) on postprandial glycaemia in individuals with Type 1 diabetes mellitus using intensive insulin therapy. Participants with Type 1 diabetes mellitus aged 7-40 years consumed six 150 ml whey isolate protein drinks [0 g (control), 12.5, 25, 50, 75 and 100] and two 150 ml glucose drinks (10 and 20 g) without insulin, in randomized order over 8 days, 4 h after the evening meal. Continuous glucose monitoring was used to assess postprandial glycaemia. Data were collected from 27 participants. Protein loads of 12.5 and 50 g did not result in significant postprandial glycaemic excursions compared with control (water) throughout the 300 min study period (P > 0.05). Protein loads of 75 and 100 g resulted in lower glycaemic excursions than control in the 60-120 min postprandial interval, but higher excursions in the 180-300 min interval. In comparison with 20 g glucose, the large protein loads resulted in significantly delayed and sustained glucose excursions, commencing at 180 min and continuing to 5 h. Seventy-five grams or more of protein alone significantly increases postprandial glycaemia from 3 to 5 h in people with Type 1 diabetes mellitus using intensive insulin therapy. The glycaemic profiles resulting from high protein loads differ significantly from the excursion from glucose in terms of time to peak glucose and duration of the glycaemic excursion. This research supports recommendations for insulin dosing for large amounts of protein. © 2015 The Authors. Diabetic Medicine published by John Wiley & Sons Ltd on behalf of Diabetes UK.

Diabetes Mellitus is a metabolic disorder which is characterized by chronicle hypertensive glucose. Automatics detection of diabetes mellitus is still challenging. This study detected diabetes mellitus by using kernel k-Means algorithm. Kernel k-means is an algorithm which was developed from k-means algorithm. Kernel k-means used kernel learning that is able to handle non linear separable data; where it differs with a common k-means. The performance of kernel k-means in detecting diabetes mellitus is also compared with SOM algorithms. The experiment result shows that kernel k-means has good performance and a way much better than SOM.

Novel mathematical models with open and closed-loop control for type 1 or type 2 diabetes mellitus were developed to improve understanding of the glucose-insulin regulatory system. A hybrid impulsive glucose-insulin model with different frequencies of glucose infusions and insulin injections was analyzed, and the existence and uniqueness of the positive periodic solution for type 1 diabetes, which is globally asymptotically stable, was studied analytically. Moreover, permanence of the system for type 2 diabetes was demonstrated which showed that the glucose concentration level is uniformly bounded above and below. To investigate how to prevent hyperinsulinemia and hyperglycemia being caused by this system, we developed a model involving periodic intakes of glucose with insulin injections applied only when the blood glucose level reached a given critical glucose threshold. In addition, our numerical analysis revealed that the period, the frequency and the dose of glucose infusions and insulin injections are crucial for insulin therapies, and the results provide clinical strategies for insulin-administration practices.

General aspects of diabetes mellitus.
Alam, Uazman; Asghar, Omar; Azmi, Shazli; Malik, Rayaz A
2014-01-01
Diabetes mellitus is a heterogeneous group of disorders characterized by hyperglycemia due to an absolute or relative deficit in insulin production or action. The chronic hyperglycemia of diabetes mellitus is associated with end organ damage, dysfunction, and failure, including the retina, kidney, nervous system, heart, and blood vessels. The International Diabetes Federation (IDF) estimated an overall prevalence of diabetes mellitus to be 366 million in 2011, and predicted a rise to 552 million by 2030. The treatment of diabetes mellitus is determined by the etiopathology and is most commonly subdivided in type 1 and type 2 diabetes mellitus. There is a greater propensity towards hyperglycemia in individuals with coexisting genetic predisposition or concomitant drug therapy such as corticosteroids. The screening for diabetes mellitus may either be in the form of a 2hour oral glucose tolerance test, or via HbA1c testing, as recently recommended by the American Diabetes Association (ADA). Strong associations have been shown in observational studies suggesting poor clinical outcomes both with chronic hyperglycemia and acutely in intensive care settings. However, tight glycemic control in this setting is a contentious issue with an increased incidence of hypoglycemia and possible increase in morbidity and mortality. In a critically ill patient a glucose range of 140-180mg/dL (7.8-10.0mmol/L) should be maintained via continuous intravenous insulin infusion.

Diabetes Mellitus (DM) is reported with and associated to oral alterations, with conflicting results. The aim of this study was to identify the prevalence of oral soft tissue alterations in type 2 diabetes mellitus patients. Socioeconomic variables, gender, heredity, capillary glucose control and local factors (prosthesis, dry mouth sensation) were analyzed in 196 diabetic and non-diabetic patients enrolled in HIPERDIA, at 41 Health units of Natal, Brazil. A case study. The last blood glucose mean was 177.0 mg/dl for diabetics and 89.46 mg/dl for non-diabetics. Mean capillary blood glucose was elevated in diabetics (215.95 mg/dl); it was 102.31 mg/dl in non-diabetics. The family history confirmed the heredity nature of the disease in 68.8% of diabetic patients (n = 66) (p < 0.001); salivary flow was 49% (n = 47) in diabetics, and 34% (n = 34) in non-diabetics. Candidiasis was present in 30.5% of diabetic patients (n=29) and 36% of non-diabetics (n=36). Both groups had lesions in the palate - 81.4% (n = 35) in diabetics, and 71.1% in non-diabetics (n = 27) (p = 0.68). The alterations are not related to diabetes and are present independently of having or not type 2 Diabetes Mellitus.

Candidal colonization in complete denture wearers is a commonly encountered condition that worsens in the presence of untreated Diabetes Mellitus. The aim of this study was to evaluate the correlation between oral candidiasis in denture-bearing mucosa and elevated blood glucose levels in complete denture wearers and to evaluate the effect of oral hypoglycemic drug therapy in controlling oral candidal colonization in denture-bearing mucosa of complete denture wearers with Type II Diabetes Mellitus. This prospective observational study involved the participation of 15 complete denture wearers with Type II Diabetes Mellitus. The sample collection was made prior and after oral hypoglycaemic drug intervention, by swabbing the rugal surfaces of palatal mucosa, cultured and the density of the candidal colony formed was analyzed and interpreted as colony forming units (CFU) per mL. The candidal samples CFU and corresponding pre- and post-prandial blood glucose levels were estimated, analyzed and compared using Karl Pearson correlation analysis and paired t-test (α = 0.05). The Karl Pearson correlation analysis showed that there was a positive correlation between the blood glucose levels (PPS and FBS) and the candidal colonization (CFU) (P < 0.05). The mean values of all the variables were analyzed using the paired t-test. There was significant reduction in the mean values of blood glucose levels (P < 0.001) and the mean values of the CFU (P < 0.001) following oral hypoglycemic drug therapy. Positive correlation was observed between oral candidiasis in complete denture-bearing mucosa and elevated blood glucose levels and oral hypoglycemic drug therapy has a positive effect in controlling oral candidal colonization in complete denture wearers with Type II Diabetes Mellitus.

This review focuses on the pathophysiological and clinical aspects of diabetes mellitus occurring in patients with Cushing disease (CD). Insulin resistance and impairment in insulin secretion are both involved in the pathogenesis of glucocorticoid-induced diabetes. Correction of glucocorticoid excess does not always resolve abnormalities of glucose homeostasis, and correction of hyperglycaemia is specifically required. In fact, insulin resistance may persist even after correction of glucocorticoid excess and diabetes needs to be treated for long term. On the other hand, emerging drugs used in the treatment of CD, such as the novel somatostatin analog pasireotide, may have direct effects on glucose homeostasis regardless of control of cortisol excess. Diabetes mellitus is a frequent and early complication of CD with important diagnostic, prognostic and therapeutic implications. Specifically, diagnosis of CD in patients with diabetes may be difficult due to potential misinterpretation of markers of cortisol hypersecretion. Moreover, diabetes mellitus is often difficult to be controlled in CD requiring a careful and dedicated therapeutic approach. Finally, the coexistence of diabetes may influence the therapeutic decision making in CD, since drugs used in this setting may variably influence glucose homeostasis regardless of control of hypercortisolism.

Hypoglycaemia in diabetes mellitus: epidemiology and clinical implications.
Frier, Brian M
2014-12-01
Hypoglycaemia is a frequent adverse effect of treatment of diabetes mellitus with insulin and sulphonylureas. Fear of hypoglycaemia alters self-management of diabetes mellitus and prevents optimal glycaemic control. Mild (self-treated) and severe (requiring help) hypoglycaemia episodes are more common in type 1 diabetes mellitus but people with insulin-treated type 2 diabetes mellitus are also exposed to frequent hypoglycaemic events, many of which occur during sleep. Hypoglycaemia can disrupt many everyday activities such as driving, work performance and leisure pursuits. In addition to accidents and physical injury, the morbidity of hypoglycaemia involves the cardiovascular and central nervous systems. Whereas coma and seizures are well-recognized neurological sequelae of hypoglycaemia, much interest is currently focused on the potential for hypoglycaemia to cause dangerous and life-threatening cardiac complications, such as arrhythmias and myocardial ischaemia, and whether recurrent severe hypoglycaemia can cause permanent cognitive impairment or promote cognitive decline and accelerate the onset of dementia in middle-aged and elderly people with diabetes mellitus. Prevention of hypoglycaemia is an important part of diabetes mellitus management and strategies include patient education, glucose monitoring, appropriate adjustment of diet and medications in relation to everyday circumstances including physical exercise, and the application of new technologies such as real-time continuous glucose monitoring, modified insulin pumps and the artificial pancreas.

We measured the effects of a single bout of exercise on diurnal and nocturnal oxidative stress and glycaemic variability in obese subjects with type 2 diabetes mellitus or impaired glucose tolerance versus obese healthy controls. Subjects (in random order) performed either a single 30-min bout of moderate-intensity exercise or remained sedentary for 30 min at two separate visits. To quantify glycaemic variability, standard deviation of glucose (measured by continuous glucose monitoring system) and continuous overlapping net glycaemic action of 1-h intervals (CONGA-1) were calculated for three 12-h intervals during each visit. Oxidative stress was measured by 15-isoprostane F(2t) levels in urine collections for matching 12-h intervals. Exercise reduced daytime glycaemic variability (ΔCONGA-1 = -12.62 ± 5.31 mg/dL, p = 0.04) and urinary isoprostanes (ΔCONGA-1 = -0.26 ± 0.12 ng/mg, p = 0.04) in the type 2 diabetes mellitus/impaired glucose tolerance group. Daytime exercise-induced change in urinary 15-isoprostane F(2t) was significantly correlated with both daytime standard deviation (r = 0.68, p = 0.03) and with subsequent overnight standard deviation (r = 0.73, p = 0.027) in the type 2 diabetes mellitus/impaired glucose tolerance group. Exercise significantly impacts the relationship between diurnal oxidative stress and nocturnal glycaemic variability in individuals with type 2 diabetes mellitus/impaired glucose tolerance. © The Author(s) 2015.

To explore and describe lived experience of blood glucose self-monitoring among pregnant Thai women with gestational diabetes mellitus. Self-monitoring of blood glucose is an essential practice among pregnant women with diabetes to prevent complications in pregnancy and the newborn infant. Phenomenological research was employed to understand lived experiences in glycemic control. Thirty participants were approached and interviewed using a semistructured interview guides. Qualitative data were analysed following Colaizzi's method. The findings revealed three themes: being worried about diabetes and blood testing, trying to control it and being patient for the child. Their worry comprised three dimensions: (1) wondering about the impacts of diabetes on the child, (2) concern about maternal health and (3) being worried about doing blood test. Trying to control diabetes was composed of three dimensions: (1) learning to test blood glucose, (2) being afraid of elevated blood sugar and (3) being aware of what to eat. Being patient for the child was composed of three dimensions: (1) overcoming food desires, (2) tolerating the fingerprick pain and (3) satisfaction with the outcomes. Women with gestational diabetes experienced being worried and afraid regarding blood glucose self-monitoring; however, they could overcome and tolerate this with some difficulties. These findings can be used to guide nursing practice in assessment of perception and response towards blood glucose self-monitoring in order to improve achievement of a good glycaemic control among pregnant women with gestational diabetes mellitus. © 2016 John Wiley & Sons Ltd.

Considering the health benefits of sesame oil and rice bran oil, the study was conducted to determine the extent to which the daily use of this blend of oils controls hyperglycemia and improves the lipid profile. In this 8-week open-label randomized dietary intervention study, 300 type 2 diabetes mellitus patients and 100 normoglycemic subjects were grouped as 1) normoglycemic subjects (n = 100) treated with sesame oil blend Vivo (Adani Wilmar, Ahmedabad, Gujarat, India), 2) type 2 diabetes mellitus patients treated with sesame oil blend (n = 100), 3) type 2 diabetes mellitus patients treated with glibenclamide (n = 100; 5 mg/d), and 4) type 2 diabetes mellitus patients treated in combination of glibenclamide (5 mg/d) and sesame oil blend (n = 100). Twelve-hour fasting blood glucose, glycated hemoglobin (HbA1c), and lipid profile followed by postprandial blood glucose were measured at baseline. Sesame oil blend was supplied to the respective groups, who were instructed to use as cooking oil for 8 weeks. Fasting and postprandial blood glucose was measured at week 4 and week 8, while HbA1c and lipid profile were measured at week 8. At week 4 and week 8, type 2 diabetes mellitus patients treated with sesame oil blend or glibenclamide or combination of glibenclamide and sesame oil blend showed significant reduction of fasting and postprandial blood glucose (P <.001). HbA1c, total cholesterol, triglycerides, low-density lipoprotein cholesterol, and non-high-density lipoprotein cholesterol were significantly reduced (P <.001), while high-density lipoprotein cholesterol was significantly increased at week 8 (P <.001) in type 2 diabetes mellitus patients treated with the sesame oil blend or combination of glibenclamide and sesame oil blend; whereas glibenclamide-alone-treated type 2 diabetes mellitus patients showed a significant reduction of HbA1c (P <.001) only. A novel blend of 20% cold-pressed unrefined sesame oil and 80% physically refined rice bran oil as cooking oil, lowered hyperglycemia and improved the lipid profile in type 2 diabetes mellitus patients.

Rats with intrauterine growth retardation and catch-up growth (CG-IUGR) after birth show increased susceptibility to diabetes mellitus in adulthood. The expression of glucose transporter type 4 (GLUT4) decreases in female IUGR offspring rats with seminutrient restriction during pregnancy. However, the male CG-IUGR rats also display an increased susceptibility to diabetes mellitus in adulthood. Whether there is another factor, besides GLUT4, in male CG-IUGR rat that mediates their susceptibility to diabetes mellitus? The male IUGR rats with catch-up growth were selected as the research objects. CG-IUGR rats had an increased fasting blood glucose level, and increased serum total cholesterol, triglyceride and free fatty acid levels. Glucose tolerance test and insulin tolerance test showed higher glucose levels and much higher insulin levels after a glucose load in CG-IUGR. The mRNA and protein expressions of IRS-2 in liver tissue, and IRS-1 and GLUT4 in skeletal muscle in CG-IUGR rats were down-regulated, but only the GLUT4 down-regulation displayed strong negative correlations with the decreased glucose tolerance capability by Pearson's analysis. The methylation patterns of CpG islands in the promoter regions of IRS-1, IRS-2 and GLUT4 in CG-IUGR rats varied, which was not significantly correlated with their expressions. The male CG-IUGR rats showed decreased glucose tolerant capability, suggesting increased susceptibility to diabetes mellitus in adulthood. The GLUT4 down-regulation may play a vital role in the development of decreased glucose tolerance in male CG-IUGR rats. The methylation modification of the promoter region of GLUT4 does not appear to be involved in its expression. ©The Author 2016.

The aims of the present study were to investigate the performance of a novel sandwich enzyme-linked immunosorbent assay (ELISA) for measuring glucagon (1-29) with monoclonal antibodies against both the C- and N-terminal regions of glucagon (1-29), and to analyze the differences in plasma levels and responses of glucagon (1-29) to oral glucose loading in normal glucose tolerance (NGT) subjects and patients with type 2 diabetes mellitus. The cross-reactivity against proglucagon fragments using the ELISA kit and two types of conventional radioimmunoassay (RIA) kits was evaluated. A 75-g oral glucose tolerance test was carried out with NGT subjects and patients with type 2 diabetes mellitus, and the glucagon (1-29) concentration was measured using three types of kit. The ELISA kit clearly had the lowest cross-reactivity against miniglucagon (19-29) and glicentin (1-61). The oral glucose tolerance test was carried out with 30 NGT and 17 patients with type 2 diabetes mellitus. The glucagon (1-29) levels measured by the ELISA kit after glucose loading were significantly higher at all time-points in the type 2 diabetes mellitus group than in the NGT group. However, the glucagon (1-29) levels measured by one RIA kit were significantly higher in the NGT group, and those measured with the other RIA kit were approximately the same among the groups. The novel sandwich ELISA accurately determines plasma glucagon (1-29) concentrations with much less cross-reactivity against other proglucagon fragments than conventional RIA kits.

To assess the association between low serum creatinine levels and an increased risk of type 2 diabetes mellitus and dysglycemia. We conducted a retrospective cohort study of 3313 Japanese male workers aged 30-55 years, who underwent annual health check-ups during 2001-2008 and showed no type 2 diabetes mellitus, and underwent follow-up examinations until March 2013. Dysglycemia was defined as a fasting plasma glucose concentration of ≥ 110 mg/dL (6.1 mmol/L), or a non-fasting plasma glucose concentration of ≥ 140 mg/dL (7.8 mmol/L). A Cox proportional model was used to calculate HRs and 95% CIs for developing type 2 diabetes mellitus or dysglycemia. During the median 6.7-year follow-up, there were 207 cases of incident type 2 diabetes mellitus and 596 cases of incident dysglycemia, including 115 cases of type 2 diabetes mellitus among the subjects with normal glucose concentrations at baseline. After adjustment for age, body mass index and known diabetes risk factors, the multivariable HR of type 2 diabetes mellitus for the lowest category of serum creatinine (<0.7 mg/dL) vs the highest category (0.9-1.1 mg/dL) was 1.9 (95% CI 1.2 to 2.9; P for trend 0.03). The multivariable HRs of dysglycemia for the lowest category of serum creatinine versus the highest category was 1.5 (95% CI 1.1 to 1.9; P for trend 0.01). Low serum creatinine levels were associated with an increased risk of type 2 diabetes mellitus and dysglycemia. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Salivary flow and composition in diabetic and non-diabetic subjects.
Lasisi, T J; Fasanmade, A A
2012-06-07
The study investigated the effects of type 2 diabetes mellitus on salivary flow and composition in humans compared to healthy sex and age matched controls. Forty adult human subjects divided into 20 diabetic and 20 non-diabetic healthy subjects were included. Saliva samples were collected and analysed for glucose, total protein, calcium, sodium, potassium, chloride and bicarbonate. Salivary flow rate was also determined. The results showed that salivary glucose and potassium levels were significantly higher (p = 0.01 and 0.002 respectively) in diabetic patients compared with non-diabetic participants. It was also found that the diabetic patients had significant reduction in salivary flow rate when compared with non-diabetic individuals. In contrast, there was no significant difference in levels of total protein, Na+, Ca++, Cl- and HCO3- between the two groups. These results suggest that some oral diseases associated with diabetes mellitus may be due to altered levels of salivary glucose, potassium and flow.

Need for Better Diabetes Treatment: The Therapeutic Potential of NMDA Receptor Antagonists.
Welters, A; Lammert, E; Mayatepek, E; Meissner, T
2017-01-01
Diabetes mellitus is the most common metabolic disorder in children and adolescents. Optimal control of blood glucose concentration is essential to prevent acute and diabetic long-term complications. The options to treat diabetes have clearly improved over the last decades, however, to date neither type 1 diabetes nor type 2 diabetes mellitus can be cured. Therefore, diabetes research aims at developing β-cell protective agents that prevent or even reverse diabetes onset. N-methyl-D-aspartate receptors (NMDARs) are glutamate-gated ion channels that are widely expressed in the central nervous system (CNS) where they hold central roles in CNS function. NMDAR dysfunction is associated with several neurological and psychiatric disorders and therefore NMDAR modulators have several potential therapeutic indications. Only little is known about the role of pancreatic NMDA receptors. Our data provide evidence that inhibition of pancreatic NMDARs, either genetically or pharmacologically with the over-the-counter drug dextromethorphan, increases glucose-stimulated insulin secretion from mouse and human pancreatic islets, improves glucose tolerance in mice and individuals with diabetes and promotes islet cell survival under diabetogenic conditions. Thus, our data indicate for the first time that NMDAR antagonists could serve as adjunct treatment for diabetes mellitus. The development of a safe, blood glucose lowering and particularly β-cell protective medication would significantly enhance current diabetes treatment. © Georg Thieme Verlag KG Stuttgart · New York.

This study aimed to investigate the prevalence of glucosuria and the characteristics of diabetes in schoolchildren as detected by a school urine glucose screening program implemented from 2010 to 2013 in the Jeonbuk province area of Korea. A total of 110 children without known diabetes were analyzed. They were checked with an oral glucose tolerance test (OGTT) with other laboratory tests and their clinical data were collected. A total of 707,238 schoolchildren from a school population of 1,064,999 were screened for glucosuria. In total, over a 4-year period, 545 schoolchildren (0.077%) were positive for glucosuria on the second urine test. The prevalence of glucosuria was more common among middle and high schoolchildren than among elementary schoolchildren. Among 110 students who completed the OGTT to confirm diabetes, 40 were diagnosed with diabetes mellitus (DM); 39 children, type 2 diabetes mellitus (T2DM) and 1 child, slowly progressive insulin dependent diabetes mellitus (SPIDDM). The mean annual incidence of diabetes was 5.6 per 100,000 schoolchildren and adolescents. The subjects with diabetes diagnosed through the urine screening test showed minimal or no symptoms of diabetes. The students with diabetes were more likely to be woman and obese, and they have a higher body mass index, higher cholesterol, triglyceride, insulin, C-peptide, and fasting glucosuria values than the students with normal glucose tolerance. We identified 40 new cases of diabetes in the Korean schoolchildren with asymptomatic glucosuria on urine glucose screening. This finding shows that school urine glucose screening is a feasible and simple method for early detection of asymptomatic T2DM. © 2017 The Korean Academy of Medical Sciences.

Diabetes is known to influence salivary composition and function, eventually affecting the oral cavity. We thus evaluated saliva samples for levels of glucose, amylase and total protein, and assessed salivary flow rate in diabetics and healthy non-diabetics. We also analyzed these parameters with regard to duration and type of diabetes mellitus and gender, and aimed to assess the interrelationships among the variables included in the study. A total of 120 age- and sex-matched participants were divided into 3 groups of 40 each; the uncontrolled diabetic group, the controlled diabetic group and the healthy non-diabetic group. Salivary investigations were performed using unstimulated whole saliva. Mean salivary glucose levels were found to be significantly elevated in both uncontrolled and controlled diabetics, as compared to healthy non-diabetics. There were significant decreases in mean salivary amylase levels in controlled diabetics when compared to healthy non-diabetics. Other than salivary glucose, no other parameters were found to be markedly affected in diabetes mellitus. Further research is needed to explore the clinical implications of these study results.

Considering folkloric use of Tribulus terrestris (T. terrestris) in diabetes and proven anti-hyperglycemic and anti-hyperlipidemic effects of T. terrestris in animal studies, we aimed to evaluate the efficacy of the hydro alcoholic extract of T. terrestris on the serum glucose and lipid profile of women with diabetes mellitus. Ninety-eight diabetic women were randomly allocated to receive the T. terrestris (1000 mg/day) or placebo for three months. The patients were evaluated in terms of the fasting blood glucose, 2-hour postprandial glucose, glycosylated hemoglobin and lipid profile. T. terrestris showed a significant blood glucose lowering effect in diabetic women compared to placebo (P<0.05). Also, the total cholesterol and low-density lipoprotein of the T. terrestris group was significantly reduced compared with placebo, while no significant effect was observed in the triglyceride and high-density lipoprotein levels. This study showed preliminary promising hypoglycemic effect of T. terrestris in diabetic women.

Myostatin and irisin are two myokines related to energy metabolism, acting on skeletal muscle and recently suggested on adipose tissue in mice. However, the exact role of these myokines in humans has not been fully established. Our aim was to evaluate the relationship between serum levels of myostatin and irisin in type 2 diabetes mellitus patients and non-diabetic controls and to explore its links with metabolic parameters. Case-control study including 73 type 2 diabetes mellitus patients and 55 non-diabetic subjects as control group. Circulating myostatin and irisin levels were measured by enzyme-linked immunosorbent assays. Type 2 diabetes mellitus patients showed significantly lower myostatin levels (p = 0.001) and higher irisin levels (p = 0.036) than controls. An inverse relationship was observed between myostatin and irisin levels (p = 0.002). Moreover, in type 2 diabetes mellitus patients, after adjusting by confounder factors, myostatin was negatively related to fasting plasma glucose (p = 0.005) and to triglyceride levels (p = 0.028) while irisin showed a positive association with these variables (p = 0.017 and p = 0.006 respectively). A linear regression analysis showed that irisin and fasting plasma glucose levels were independently associated to myostatin levels and that myostatin and triglyceride levels were independently associated to irisin concentrations in type 2 diabetes mellitus patients. Our results suggest that serum levels of myostatin and irisin are related in patients with type 2 diabetes. Triglyceride and glucose levels could modulate myostatin and irisin concentrations as a compensatory mechanism to improve the metabolic state in these patients although further studies are needed to elucidate whether the action of these myokines represents an adaptative response.

Women with a history of gestational diabetes mellitus and preeclampsia are at increased risk of cardiovascular disease later in life, but the mechanism remains unclear. The aim of the study was to evaluate the association between CXC chemokine ligand 16 and indices of glucose metabolism, dyslipidemia and systemic inflammation in gestational diabetes mellitus and preeclampsia. This sub-study of the population-based prospective cohort included 310 women. Oral glucose tolerance test was performed during pregnancy and 5 years later along with lipid analysis. CXC chemokine ligand 16 was measured in plasma (protein) and peripheral blood mononuclear cells (messenger RNA) during pregnancy and at follow-up. Circulating CXC chemokine ligand 16 was higher in gestational diabetes mellitus women early in pregnancy and at follow-up, while higher in preeclampsia women late in pregnancy compared to control women. Messenger RNA of CXC chemokine ligand 16 in peripheral blood mononuclear cells were lower in gestational diabetes mellitus and preeclampsia women compared to control women. Increased circulating CXC chemokine ligand 16 level was associated with a higher apolipoprotein B and low-density lipoprotein cholesterol in gestational diabetes mellitus women but not in normal pregnancy at follow-up. Our study shows that women with gestational diabetes mellitus and preeclampsia had a dysregulated CXC chemokine ligand 16 during pregnancy, and in gestational diabetes mellitus, the increase in CXC chemokine ligand 16 early in pregnancy and after 5 years was strongly associated with their lipid profile.

The role of brain-derived neurotrophic factor (BDNF) variants on diabetes prevalence, basal adipokine levels, body weight, and cardiovascular risk factors remains unclear in obese patients. This study is aimed at analyzing the effects of rs10767664 BDNF gene polymorphism on diabetes mellitus prevalence, body weight, cardiovascular risk factors, and serum adipokine levels in obese female patients. A total of 507 obese women were enrolled in a prospective way. Biochemical evaluation and anthropometric measures were recorded. The frequency of diabetes mellitus in the group of patients with non-T allele was 20.1 and 28.3% in T-allele carriers. Logistic regression showed a risk of diabetes mellitus of 1.33 (95% CI 1.17-2.08) in subjects with T allele adjusted by age and body mass index (BMI). T-allele carriers with diabetes mellitus have a higher weight, BMI, waist circumference, blood pressure, glucose, homeostasis model assessment insulin resistance (HOMA-IR), insulin, and C-reactive protein (CRP) levels than non-T-allele carriers. rs10767664 polymorphism of BDNF gene is associated with prevalence of diabetes mellitus in obese female patients. T-allele carriers with diabetes mellitus have a higher weight, fat mass, blood pressure, level of insulin, glucose, HOMA-IR, and CRP than non-T-allele carriers. © 2017 S. Karger AG, Basel.

We report the case of a patient with relapsed classical Hodgkin lymphoma who developed fulminant type I diabetes mellitus as a severe adverse event of treatment with the anti-programmed cell death-1 (PD-1) antibody, nivolumab. On the first day of the sixth cycle, the blood glucose level was markedly elevated (375 mg/dL). Although neither ketoacidosis nor ketonuria was detected, the markedly acute onset of the hyperglycemia was consistent with the typical clinical course of fulminant type I diabetes mellitus, and this diagnosis was supported by clinical data. All autoantibodies associated with type I diabetes mellitus were negative. The endogenous insulin secretion ceased completely within 2 weeks. After the blood glucose level was brought under control, nivolumab was resumed and continued without other major adverse events. Human leukocyte antigen (HLA) analysis revealed that the patient carried the HLA-B*4002 haplotype, a susceptibility allele for this type of diabetes mellitus. This case suggests that fulminant type I diabetes mellitus may be triggered by nivolumab in patients with a genetic background associated with the condition, warranting careful future consideration of this particular adverse event.

[Diabetes mellitus secondary to an endocrine pathology : when to think about it ?
Rouiller, Nathalie; Jornayvaz, François R
2017-05-31
An endocrine disease can be associated with glucose intolerance or diabetes mellitus, and the latter can falsely be considered as type 2 diabetes. Glycemic imbalance can be a direct or indirect consequence of excessive hormone production. Endocrine diseases such as acromegaly, Cushing's syndrome and pheochromocytoma can increase glucose production and cause insulin resistance. Hyperthyroidism, hyperaldosteronism, glucagonoma and somatostatinoma lead to hyperglycemia by other physiopathological mechanisms detailed in this article. When a clinical picture suggests an endocrine disease, several analyses need to be done in order to avoid treatment escalation of diabetes.

Self blood glucose monitoring is an important context of self care in the management of diabetes mellitus. All the guidelines must be followed while performing self blood glucose monitoring and tracking of values is essential to facilitate the physician while titrating the drugs and /or doses of anti diabetes medication. Self titration by patients following self monitoring must be discouraged. To assess the knowledge and practice of self blood glucose monitoring among diabetes patients and extent of self titration of anti diabetes medicines among diabetes patients based on self blood glucose monitoring. This pilot, cross-sectional, observational study was conducted using a validated questionnaire among adult male and female diabetes patients performing self blood glucose monitoring at home. Diabetes patients with complications and juvenile diabetes patients were excluded. Out of 153 patients surveyed, only 37 (24.1%) (20 males, 17 females) patients were aware and have been following self blood glucose monitoring appropriately. About 116 (75.8%) (64 males, 52 females) of patients were devoid of adequate knowledge and did not practice self blood glucose monitoring in a proper way. Ninety eight (64.05%) accepted that they self titrate their anti diabetic medicines based on self monitoring. Self monitoring of blood glucose should be encouraged and patients should be taught importance of following correct steps and tracking of self monitoring by physician or diabetes educator.

The potential detrimental effect of diabetes mellitus and admission glucose level (AGL) on outcomes after stroke thrombolysis is unclear. We evaluated outcomes of patients treated by intravenous and/or intra-arterial therapy, according to diabetes mellitus and AGL. We analyzed data from a patient registry (n=704) and conducted a systematic review of previous observational studies. The primary study outcome was the percentage of patients who achieved a favorable outcome (modified Rankin score ≤2 at 3 months). We identified 54 previous reports that evaluated the effect of diabetes mellitus or AGL on outcomes after thrombolysis. In an unadjusted meta-analysis that included our registry data and previous available observational data, diabetes mellitus was associated with less favorable outcome (odds ratio [OR], 0.76; 95% confidence interval [CI], 0.73-0.79) and more symptomatic intracranial hemorrhage (OR, 1.38; 95% CI, 1.21-1.56). However, in multivariable analysis, diabetes mellitus remained associated with less favorable outcome (OR, 0.77; 95% CI, 0.69-0.87) but not with symptomatic intracranial hemorrhage (OR, 1.11; 95% CI, 0.83-1.48). In unadjusted and in adjusted meta-analysis, higher AGL was associated with less favorable outcome and more symptomatic intracranial hemorrhage; the adjusted OR (95% CI) per 1 mmol/L increase in AGL was 0.92 (0.90-0.94) for favorable outcome, and 1.09 (1.04-1.14) for symptomatic intracranial hemorrhage. These results confirm that AGL and history of diabetes mellitus are associated with poor clinical outcome after thrombolysis. AGL may be a surrogate marker of brain infarction severity rather than a causal factor. However, randomized controlled evidences are needed to address the significance of a tight glucose control during thrombolysis on clinical outcome.

This study was designed to evaluate the metabolic response to Corinthian raisins in healthy and in patients with type 2 diabetes mellitus. Healthy subjects (n = 15) and diabetic patients (n = 15) received 74 g raisins or 50 g glucose as reference food. Blood samples were collected at time 0 (before the consumption) and 30, 60, 90, 120, 150 and 180 min after raisin or glucose consumption. There was no significant difference in baseline glucose and insulin between raisins and reference in both groups. The difference at glucose peaks between raisins and reference was significant in healthy and in diabetics. Glycemic and insulinemic responses were decreased after raisin consumption compared to reference. An estimate of the glycemic index would be 66.3 ± 3.4.

[Lifestyle of elderly patients with diabetes mellitus].
Fukuoka, Yuki; Yamada, Yuichiro
2013-11-01
In elderly people, glucose tolerance is deteriorated and the incidence of diabetes mellitus is increased, due to decreased muscle mass and physical activity, declining pancreatic beta cell function, and other factors. Diabetes mellitus is an important risk factor for arteriosclerosis development in the elderly. Precise diagnosis and adequate treatment are necessary to prevent cerebrovascular and ischemic heart diseases. Elderly patients with diabetes mellitus are characteristically afflicted with more complications, impaired activities of daily living, cognitive function decline, and family environment problems, as compared with young and middle-aged diabetics. Therefore, tailor-made rather than uniform therapy becomes important. Lifestyle modification is the basis of diabetes treatment. Herein, we describe "prevention and management" of diabetes mellitus, focusing on the lifestyles of elderly diabetics.

Diabetes and glucose intolerance are common complications of chronic pancreatitis, yet clinical guidance on their detection, classification, and management is lacking. A working group reviewed the medical problems, diagnostic methods, and treatment options for chronic pancreatitis-associated diabetes for a consensus meeting at PancreasFest 2012. Guidance Statement 1.1: Diabetes mellitus is common in chronic pancreatitis. While any patient with chronic pancreatitis should be monitored for development of diabetes, those with long-standing duration of disease, prior partial pancreatectomy, and early onset of calcific disease may be at higher risk. Those patients developing diabetes mellitus are likely to have co-existing pancreatic exocrine insufficiency. Guidance Statement 1.2: Diabetes occurring secondary to chronic pancreatitis should be recognized as pancreatogenic diabetes (type 3c diabetes). Guidance Statement 2.1: The initial evaluation should include fasting glucose and HbA1c. These tests should be repeated annually. Impairment in either fasting glucose or HbA1c requires further evaluation. Guidance Statement 2.2: Impairment in either fasting glucose or HbA1c should be further evaluated by a standard 75 g oral glucose tolerance test. Guidance Statement 2.3: An absent pancreatic polypeptide response to mixed-nutrient ingestion is a specific indicator of type 3c diabetes. Guidance Statement 2.4: Assessment of pancreatic endocrine reserve, and importantly that of functional beta-cell mass, should be performed as part of the evaluation and follow-up for total pancreatectomy with islet autotransplantation (TPIAT). Guidance Statement 3: Patients with pancreatic diabetes shall be treated with specifically tailored medical nutrition and pharmacologic therapies. Physicians should evaluate and treat glucose intolerance in patients with pancreatitis. Copyright © 2013 IAP and EPC. All rights reserved.

Diabetes Mellitus is a metabolic disorder characterized by abnormal lipid and glucose metabolism. Various modes of adjuvant therapy have been advocated to ameliorate insulin resistance. This study was intended to assess the effects of antioxidants; alpha lipoic acid (ALA), omega 3 fatty acid and vitamin E on parameters of insulin sensitivity (blood glucose and HbA1c) in patients of type 2 diabetes mellitus with documented insulin resistance. It was a prospective, randomized, double blind, placebo controlled, single centered study. 104 patients with type 2 diabetes mellitus with insulin resistance were recruited. They were given ALA, omega 3 fatty acid, vitamin E or placebo. Fasting blood glucose and HbA1c were measured at first visit (V1) and after 90 days (V2). Statistical analysis was carried out by paired t-test by using SPSS software version 11 (SPSS, Chicago, USA). Analysis of baseline (V1) vs. end of treatment period (V2) parameters, showed significant decrease in HbA1c in the three treatment group. We also observed decrease in fasting blood glucose in the three treatment group but it was not statistically significant (Gr. I = 0.51, Gr. II = 0.05, Gr. III = 0.22, Gr. IV = 0.88). ALA, Omega 3 fatty acid and vitamin E can be used as add on therapy in patients with type 2 diabetes mellitus to improve insulin sensitivity and lipid metabolism.

Gestational diabetes mellitus, defined as any carbohydrate intolerance first diagnosed during pregnancy, is associated with a variety of adverse outcomes, both for the mother and her child. To investigate the impact of a structured exercise programme which consisted of aerobic and resistance exercises on the parameters of glycaemic control and other health-related outcomes in pregnant women diagnosed with gestational diabetes mellitus. Thirty-eight pregnant women diagnosed with gestational diabetes mellitus were randomised to two groups. Experimental group was treated with standard antenatal care for gestational diabetes mellitus, and regular supervised exercise programme plus daily brisk walks of at least 30min. Control group received only standard antenatal care for gestational diabetes mellitus. The exercise programme was started from the time of diagnosis of diabetes until birth. It was performed two times per week and sessions lasted 50-55min. The experimental group had lower postprandial glucose levels at the end of pregnancy (P<0.001). There was no significant difference between groups in the level of fasting glucose at the end of pregnancy. Also, there were no significant differences in the rate of complications during pregnancy and birth, need for pharmacological therapy, maternal body mass and body fat percentage gains during pregnancy, and neonatal Apgar scores, body mass and ponderal index. Neonatal body mass index was higher in the experimental group (P=0.035). The structured exercise programme had a beneficial effect on postprandial glucose levels at the end of pregnancy.

Metabolic disorders are a group of disorders, due to the disruption of the normal metabolic process at a cellular level. Diabetes Mellitus and Tyrosinaemia are the majorly reported metabolic disorders. Among them, Diabetes Mellitus is a one of the leading metabolic syndrome, affecting 5 to 7 % of the population worldwide and mainly characterised by elevated levels of glucose and is associated with two types of physiological event disturbances such as impaired insulin secretion and insulin resistance. Up to now, various treatment strategies are like insulin, alphaglucosidase inhibitors, biguanides, incretins were being followed. Concurrently, various novel therapeutic strategies are required to advance the therapy of Diabetes mellitus. For the last few decades, there has been an extensive research in understanding the metabolic pathways involved in Diabetes Mellitus at the cellular level and having the profound knowledge on cell-growth, cell-cycle, and apoptosis at a molecular level provides new targets for the treatment of Diabetes Mellitus. Receptor signalling has been involved in these mechanisms, to translate the information coming from outside. To understand the various receptors involved in these pathways, we must have a sound knowledge on receptors and ligands involved in it. This review mainly summarises the receptors and ligands which are involved the Diabetes Mellitus. Finally, researchers have to develop the alternative chemical moieties that retain their affinity to receptors and efficacy. Diabetes Mellitus being a metabolic disorder due to the glucose surfeit, demands the need for regular exercise along with dietary changes.

To investigate whether serum levels of butyrylcho-linesterase activity, cystatin C, and pre-albumin has the potential value as γ-glutamyl transferase in reflecting gestational diabetes mellitus and its fetal outcome. Seventy-six gestational diabetes mellitus women and 76 pregnancies with normal glucose tolerance in the second trimester were enrolled. Maternal serum parameters of butyrylcholinesterase activity, γ-glutamyl transferase, cystatin C, and pre-albumin were detected and evaluated. The pregnant complications and fetal outcome were also evaluated. Levels of butyrylcholinesterase activity, γ-glutamyl transferase, cystatin C, pre-albumin and glycemic variables were higher in the gestational diabetes mellitus patients than in the controls. Levels of butyrylcholinesterase activity were significantly correlated to the levels of fasting plasma glucose, cystatin C, and γ- glutamyl transferase (p < 0.05) in the gestational diabetes mellitus group. There were statistical differences in cases of preterm delivery, preeclampsia and postpartum hemorrhage. Higher levels of γ-glutamyl transferase and pre-albumin were risk markers for gestational diabetes mellitus (p < 0.05). The diagnosis curve demonstrated that γ-glutamyl transferase had a significant advantage over other markers (p < 0.001) but no significance compared with pre-albumin (p = 0.096). None of the detected markers showed predictive value for fetal outcome. Serum levels of butyrylcholinesterase activity, γ-glutamyl transferase, cystatin C and pre-albumin were correlated with gestational diabetes mellitus status but not with the fetal outcome. Pre-albumin can be equivalent as γ-glutamyl transferase in reflecting the presence of gestational diabetes mellitus.

Diabetes mellitus is associated with left ventricular hypertrophy and dysfunction. Parallel studies have also reported associations between diabetes mellitus and right ventricular dysfunction and reduced survival in patients with pulmonary arterial hypertension. However, the impact of diabetes mellitus on the pulmonary vasculature has not been well characterized. We hypothesized that diabetes mellitus and hyperglycemia could specifically influence right ventricular afterload and remodeling in patients with Group I pulmonary arterial hypertension, providing a link to their known susceptibility to right ventricular dysfunction. Using an adjusted model for age, sex, pulmonary vascular resistance, and medication use, associations of fasting blood glucose, glycated hemoglobin, and the presence of diabetes mellitus were evaluated with markers of disease severity in 162 patients with pulmonary arterial hypertension. A surrogate measure of increased pulmonary artery stiffness, elevated pulmonary arterial elastance (P = .012), along with reduced log(pulmonary artery capacitance) (P = .006) were significantly associated with the presence of diabetes mellitus in patients with pulmonary arterial hypertension in a fully adjusted model. Similar associations between pulmonary arterial elastance and capacitance were noted with both fasting blood glucose and glycated hemoglobin. Furthermore, right ventricular wall thickness on echocardiography was greater in pulmonary arterial hypertension patients with diabetes, supporting the link between right ventricular remodeling and diabetes. Cumulatively, these data demonstrate that an increase in right ventricular afterload, beyond pulmonary vascular resistance alone, may influence right ventricular remodeling and provide a mechanistic link between the susceptibility to right ventricular dysfunction in patients with both diabetes mellitus and pulmonary arterial hypertension.

Background: Idiopathic frozen shoulder (nontraumatic) is commonly encountered in patients between the ages of 35 and 60 years in general orthopaedic practice. While the prevalence of frozen shoulder among the general population is estimated to be between 2% and 4%, a significantly higher prevalence of 10% to 22% has been reported in patients with diabetes mellitus. Since diabetic patients are more prone to develop frozen shoulder than nondiabetics, the question arises as to whether patients diagnosed as having idiopathic frozen shoulder are at greater risk to develop diabetes mellitus and should be routinely screened for this condition. Purpose: To compare the prevalence of diabetes mellitus and prediabetes among patients diagnosed with idiopathic frozen shoulder who are not known to have either diabetes mellitus or prediabetic conditions with that of an age-matched group from the general population. Study Design: Case series; Level of evidence, 4. Methods: Patients at a shoulder clinic with a diagnosis of idiopathic frozen shoulder were asked to participate in the study if they were aged between 35 to 60 years and had no known previous diagnosis of diabetes mellitus or prediabetic conditions. These patients underwent a 2-hour oral glucose tolerance test. According to their fasting and 2-hour plasma glucose levels, patients were diagnosed as normal glucose tolerance, prediabetic, or diabetic. Findings were matched with the prevalence in an age-matched general population. Results: Fifty patients completed the test. Four patients with idiopathic frozen shoulder (8%) were found to be prediabetic. No patient was found to be diabetic. All 4 patients reported a history of diabetes in their parents or siblings. Conclusion: Patients diagnosed with idiopathic frozen shoulder who are 60 years or younger and are not known diabetics have a similar probability of having diabetes or prediabetes to an age-matched population. No routine diabetic workup is warranted specifically for these patients. PMID:28812038

To evaluate effects of dietary insoluble fiber on control of glycemia in cats with naturally acquired diabetes mellitus. Randomized controlled crossover trial. 16 cats with naturally acquired diabetes mellitus. Cats were fed a diet high in insoluble fiber (HF) containing 12% cellulose (dry-matter basis) or a diet low in insoluble fiber (LF) for 24 weeks; they were fed the other diet for the subsequent 24 weeks. Caloric intake and insulin treatment were adjusted to maintain stable body weight and control of glycemia, respectively. Cats were allowed an adaptation period of 6 weeks after initiation of a diet, after which control of glycemia was evaluated at 6-week intervals for 18 weeks. Variables assessed included serum glucose concentration measured during the preprandial state, blood glycated hemoglobin concentration, serum glucose concentration measured at 2-hour intervals for 12 hours beginning at the time of the morning insulin injection, 12-hour mean serum glucose concentration, and mean fluctuation in serum glucose concentration from the 12-hour mean serum glucose concentration. Mean daily caloric intake, body weight, or daily insulin dosage did not differ significantly between cats when fed HF and LF diets. Mean preprandial serum glucose concentration, most post-prandial serum glucose concentrations, and the 12-hour mean serum glucose concentration were significantly lower when cats consumed the HF diet, compared with values when cats consumed the LF diet. These results support feeding a commercially available diet containing approximately 12% insoluble fiber (dry-matter basis) to cats with naturally acquired diabetes mellitus.

To clarify the association of the hypertriglyceridemic waist phenotype and type 2 diabetes mellitus among adults in China. In the present case-control study, we included 1,685 patients with type 2 diabetes mellitus and 7,141 normal glucose-tolerant controls from the Henan Province of China in 2011. Elevated waist circumference (GW) was defined as ≥90 cm for men and ≥80 cm for women. Hypertriglyceridemia (HT) was defined as >1.7 m mol/L triglycerides (TG) level. The association of hypertriglyceridemic waist phenotype and type 2 diabetes mellitus was investigated by sex, body mass index, physical activity, and family history of diabetes. Cases and controls differed in age, waist circumference (WC), weight, TG level, fasting glucose, body mass index, smoking status, diabetic family history, physical activity and hypertriglyceridemic waist phenotype (P < 0.05), but not alcohol drinking (P = 0.63). In the overall sample, as compared with the phenotype of normal TG level and normal WC (NTNW), normal TG level/enlarged WC (NTGW), elevated TG level/normal WC (HTNW) and elevated TG level/enlarged WC (HTGW) were associated with type 2 diabetes mellitus (odds ratio 4.14, 2.42 and 6.23, respectively). Only HTGW was consistently associated with risk of type 2 diabetes mellitus, with or without adjustment. The strongest relationship between HTGW and type 2 diabetes mellitus was for subjects with body mass index <24.0 kg/m(2) (odds ratio 6.54, 95% confidence interval 4.22-10.14) after adjustment for cofounding variables. HTGW was stably and significantly associated with risk of type 2 diabetes mellitus in adult Chinese. © 2016 The Authors.

A cross sectional survey was carried out among a multiracial workforce of 5677 staff aged 40 to 64 years at worksites in Auckland and Tokoroa to determine the prevalence of diabetes mellitus and impaired glucose tolerance (IGT). The prevalences of diabetes mellitus and IGT were both similar for men and women, but increased with age. The relative risks for diabetes mellitus and for IGT were both inversely associated with gross annual household income, independent of age and ethnicity, being 1.61 (95% Cl = 1.10, 2.37) and 1.80 (95% Cl = 1.21, 2.67) respectively, in the lowest income group (less than $30,000) compared with the highest (greater than $40,000). Compared with Europeans, the relative risk of diabetes mellitus was significantly increased among Maori (3.63; 95% Cl = 2.48, 5.32), Pacific Islanders (2.34; 95% Cl = 1.50, 3.66) and Asians (5.97; 95% Cl = 2.61, 13.65), after controlling for age, income and body mass index. The increased prevalence of diabetes mellitus among Maori and Pacific Islanders, but not in Asians, could be partly attributed to their increased levels of obesity compared with Europeans. However, other factors, in addition to obesity, explain the increased diabetes prevalence in nonEuropean groups.

A low glycemic index (GI) diet is beneficial for glucose control in patients with diabetes mellitus. This study aimed to investigate the influence of a low-GI diet on postprandial glucose levels in women with gestational diabetes mellitus (GDM). Pregnant women with GDM were randomized to receive a normal diabetic control diet or a low-GI staple diet for 5 days. A low-GI staple food was used to replace rice in lunch and dinner for the low-GI staple diet group, whereas the total energy and carbohydrate levels remained equal in both groups. Fasting and postprandial glucose levels were determined daily. A total of 140 pregnant women with GDM were included in the study, including 66 in the low-GI staple diet group and 74 in the normal diabetic diet control group. No differences existed in baseline characteristics between the 2 groups (all P > 0.05). After dietary intervention, glucose levels were significantly reduced in the low-GI staple diet group (all P < 0.01) and the control group (all P < 0.008). Postintervention glucose values after breakfast, lunch, and dinner were significantly reduced in the treatment group compared with those in the control group (all P < 0.05). The percentage changes from baseline of all glucose values were significantly greater in the treatment group than in the control group (all P < 0.05). A low-GI staple diet significantly reduces postprandial glucose levels in women with GDM.

A 5.5-y-old intact male cynomolgus macaque (Macaca fasicularis) presented with inappetence and weight loss 57 d after heterotopic heart and thymus transplantation while receiving an immunosuppressant regimen consisting of tacrolimus, mycophenolate mofetil, and methylprednisolone to prevent graft rejection. A serum chemistry panel, a glycated hemoglobin test, and urinalysis performed at presentation revealed elevated blood glucose and glycated hemoglobin (HbA1c) levels (727 mg/dL and 10.1%, respectively), glucosuria, and ketonuria. Diabetes mellitus was diagnosed, and insulin therapy was initiated immediately. The macaque was weaned off the immunosuppressive therapy as his clinical condition improved and stabilized. Approximately 74 d after discontinuation of the immunosuppressants, the blood glucose normalized, and the insulin therapy was stopped. The animal's blood glucose and HbA1c values have remained within normal limits since this time. We suspect that our macaque experienced new-onset diabetes mellitus after transplantation, a condition that is commonly observed in human transplant patients but not well described in NHP. To our knowledge, this report represents the first documented case of new-onset diabetes mellitus after transplantation in a cynomolgus macaque.

Background Recent studies have suggested that mast-cell activation and inflammation are important in obesity and diabetes. Plasma levels of mast cell proteases and the mast cell activator immunoglobulin E (IgE) may serve as novel inflammatory markers that associate with the risk of pre-diabetes and diabetes mellitus. Methods and Results A total of 340 subjects 55 to 75 years of age were grouped according to the American Diabetes Association 2003 criteria of normal glucose tolerance, pre-diabetes, and diabetes mellitus. The Kruskal-Wallis test demonstrated significant differences in plasma IgE levels (P = 0.008) among groups with different glucose tolerance status. Linear regression analysis revealed significant correlations between plasma levels of chymase (P = 0.030) or IgE (P = 0.022) and diabetes mellitus. Ordinal logistic regression analysis showed that IgE was a significant risk factor of pre-diabetes and diabetes mellitus (odds ratio [OR]: 1.674, P = 0.034). After adjustment for common diabetes risk factors, including age, sex, hypertension, body-mass index, cholesterol, homeostatic model assessment (HOMA) index, high-sensitivity C-reactive protein (hs-CRP), and mast cell chymase and tryptase, IgE remained a significant risk factor (OR: 1.866, P = 0.015). Two-variable ordinal logistic analysis indicated that interactions between hs-CRP and IgE, or between IgE and chymase, increased further the risks of developing pre-diabetes and diabetes mellitus before (OR: 2.204, P = 0.044; OR: 2.479, P = 0.033) and after (OR: 2.251, P = 0.040; OR: 2.594, P = 0.026) adjustment for common diabetes risk factors. Conclusions Both IgE and chymase associate with diabetes status. While IgE and hs-CRP are individual risk factors of pre-diabetes and diabetes mellitus, interactions of IgE with hs-CRP or with chymase further increased the risk of pre-diabetes and diabetes mellitus.

Prevention of type 2 diabetes mellitus in women with previous gestational diabetes mellitus
Moon, Joon Ho; Kwak, Soo Heon; Jang, Hak C.

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.

Given the growing rate of patients with type 2 diabetes mellitus, uncovering the effects of gene polymorphism on diabetes pathogenesis has attracted a lot of attention. Because glucose transporter 1 is involved in glucose uptake, the polymorphism of this gene may be an important risk factor in type 2 diabetes mellitus or in the progression of diabetes complications such as diabetic nephropathy. As far as the authors are concerned, this study is the first one aiming at evaluating the probable effects of solute carrier family 2 facilitated glucose transporter member 1 (SLC2A1) HaeIII polymorphism on clinical and laboratory outcomes of Kurdish patients with type 2 diabetes mellitus. This study was conducted involving 126 diabetic nephropathy patients and 150 diabetic patients without renal involvement. Serum levels of Cystatin C, fasting blood glucose, creatinine and urinary albumin; levels of glycated hemoglobin and estimated glomerular filtration rate were measured. Moreover, the Hae III polymorphism of SLC2A1 gene was determined by PCR-restriction fragment length polymorphism (RFLP). The rate of CC genotype was higher (37%) in patients with diabetic nephropathy compared with controls. There were a significant correlation between the CC genotype and risk of diabetic nephropathy. There were significant correlations between genotypes, serum Cystatin C and estimated glomerular filtration rate in patients with diabetic nephropathy. The results demonstrated the high frequency of C allele of SLC2A1 HaeIII in Kurdish patients with diabetic nephropathy. It was also found that this polymorphism is a significant risk factor for diabetic nephropathy. The effect of this polymorphism on clinical and laboratory characteristics of diabetic nephropathy patients was significant. © The Author 2015.

This study was designed to assess the reliability of blood glucose level estimation in gingival crevicular blood(GCB) for screening diabetes mellitus. 70 patients were included in study. A randomized, double-blind clinical trial was performed. Among these, 39 patients were diabetic (including 4 patients who were diagnosed during the study) and rest 31 patients were non-diabetic. GCB obtained during routine periodontal examination was analyzed by glucometer to know blood glucose level. The same patient underwent for finger stick blood (FSB) glucose level estimation with glucometer and venous blood (VB) glucose level with standardized laboratory method as per American Diabetes Association Guidelines. 1 All the three blood glucose levels were compared. Periodontal parameters were also recorded including gingival index (GI) and probing pocket depth (PPD). A strong positive correlation ( r ) was observed between glucose levels of GCB with FSB and VB with the values of 0.986 and 0.972 in diabetic group and 0.820 and 0.721 in non-diabetic group. As well, the mean values of GI and PPD were more in diabetic group than non-diabetic group with the statistically significant difference ( p < 0.005). GCB can be reliably used to measure the blood glucose level as the values were closest to glucose levels estimated by VB. The technique is safe, easy to perform and non-invasive to the patient and can increase the frequency of diagnosing diabetes during routine periodontal therapy.

Why control blood glucose levels?
Rossini, A A
1976-03-01
The controversy as to the relationship between the degree of control of diabetes and the progression of the complications of the disease has not been solved. However, in this review, various studies suggesting a relationship between the metabolic abnormality and the diabetic complications are examined. The disadvantages of the uncontrolled diabetes mellitus can be divided into two major categories-short-term and long-term. The short-term disadvantages of controlled diabetes mellitus include the following: (1) ketoacidosis and hyperosmolar coma; (2) intracellular dehydration; (3) electrolyte imbalance; (4) decreased phagocytosis; (5) immunologic and lymphocyte activity; (6) impairment of wound healing; and (7) abnormality of lipids. The long-term disadvantages of uncontrolled diabetes melitus include the following: (1) nephropathy; (2) neuropathy; (3) retinopathy; (4) cataract formation; (5) effect on perinatal mortality; (6) complications of vascular disease; and (7) the evaluation of various clinical studies suggesting the relationship of elevated blood glucose levels and complications of diabetes mellitus. It is suggested that until the question of control can absolutely be resolved, the recommendation is that the blood glucose levels should be controlled as close to the normal as possible.

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 < 0.001), and high-density lipoprotein cholesterol was lower (p < 0.02) in 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 < 0.004) and decreased β-cell function (266 vs 438, p < 0.001). The frequency of rs12255372 risk allele in gestational diabetes women was significantly higher than that in euglycemic women (χ² = 8.96; p < 0.003) and confers a risk for gestational diabetes mellitus (OR = 9.1, 95% CI 2.8-29, p < 0.0002; and OR = 4.3, 95% CI 1.6-11.4, p < 0.003 based on dominant and co-dominant model, respectively). The generalized linear model showed that low beta function, high pre-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.

Diabetes mellitus (DM) was a chronic metabolic disease characterized by higher than normal blood glucose level (normal blood glucose level = = 80 -120 mg/dl). In this study, type 2 DM which mostly caused by unhealthy eating habits would be investigated. Related to eating habit, DM patients needed dietary menu planning with an extracare regarding their nutrients intake (energy, protein, fat and carbohydrate). Therefore, the measures taken were by organizing nutritious dietary menu for diabetes mellitus patients. Dietary menu with appropriate amount of nutrients was organized by considering the amount of calories, proteins, fats and carbohydrates. In this study, Goal Programming model was employed to determine optimal dietary menu variations for diabetes mellitus patients by paying attention to optimal expenses. According to the data obtained from hospitals in Yogyakarta, optimal menu variations would be analyzed by using Goal Programming model and would be completed by using LINGO computer program.

Advanced type 2 diabetes mellitus (T2DM) needing insulin therapy is common. Most conventional anti-hyperglycemic drugs have limited efficacies and significant side effects, so that better anti-hyperglycemic agents are needed. Urtica dioica L. (nettle) leaves have insulin secretagogue, PPARgamma agonistic, and alpha-glucosidase inhibitory effects. Moreover, nettle leaves are used in traditional medicine as an anti-hyperglycemic agent to treat diabetes mellitus. Thus, efficacy and safety of nettle in the treatment of patients with advanced type 2 diabetes mellitus needing insulin were studied. In this randomized double-blind placebo-controlled clinical trial, we evaluated the effects of taking nettle leaf extract (one 500 mg capsule every 8 hours for 3 months) combined with the conventional oral anti-hyperglycemic drugs on the blood levels of fasting glucose, postprandial glucose, glycosylated hemoglobin (HbA1c), creatinine and liver enzymes SGOT and SGPT, and systolic and diastolic blood pressures in 46 patients and compared with the placebo group (n = 46). At the endpoint, the extract lowered the blood levels of fasting glucose, 2 hours postprandial glucose, and HbA1c significantly (p < 0.001, p = 0.009, and p = 0.006, respectively) without any significant effects on the other parameters (p > 0.05) compared with placebo. Nettle may safely improve glycemic control in type 2 diabetic patients needing insulin therapy.

To investigate whether 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitor (statin) use is associated with an increased risk of diabetes mellitus and hyperglycemia, we performed a nested case-control study using a postmarketing surveillance database in Japan. The database cohort included 26,849 cases of statin use and 5308 cases of other lipid-lowering drug use in patients with hyperlipidemia. Participants received at least 1 type of statin, had a clear medication history of statin use, and had no complications of diabetes mellitus. Cases were defined as onset of diabetes mellitus or hyperglycemia during statin intake. For each case, 20 controls were randomly selected and matched by time point. The factors associated with an increased risk of diabetes mellitus and hyperglycemia during statin intake examined included sex, age, body mass index, statin use duration, complications, concomitant medication, and clinical laboratory tests. Statin-associated diabetes mellitus or hyperglycemia was identified based on abnormal elevation of blood glucose concentrations beyond the reference range. A total of 19,868 patients met the inclusion criteria, of whom 24 were patients in the case group. Two complicating factors, fatty liver (adjusted odds ratio 16.10) and hyperuricemia (adjusted odds ratio 28.96), were extracted for onset of diabetes mellitus or hyperglycemia. Nonalcoholic fatty liver was associated with diabetes mellitus, obesity, and insulin resistance, and hyperuricemia was associated with lifestyle. This study suggested that the onset of diabetes mellitus or hyperglycemia might be increased with statin use in patients with complications of fatty liver and hyperuricemia. © 2018, The American College of Clinical Pharmacology.

Previous epidemiologic studies have demonstrated a positive association between serum C-reactive protein (CRP) level and diabetes mellitus. However among US race-ethnicities, the putative association between CRP and diabetes mellitus in non-Hispanic Blacks is not clear. We specifically examined the association between high-sensitivity CRP level and diabetes mellitus in a representative sample of US non-Hispanic blacks. Cross-sectional study among 1,479 National Health and Nutrition Examination Survey 1999-2002 non-Hispanic black participants aged > or = 20 years. Main outcome-of-interest was the presence of diabetes mellitus (fasting plasma glucose > or = 126 mg/dL, non-fasting plasma glucose > or = 200 mg/dL, or self-reported current use of oral hypoglycemic medication or insulin) (n=204). Higher CRP levels were positively associated with diabetes mellitus, independent of smoking, waist circumference, hypertension, and other confounders. Multivariable odds ratio (OR) [95% confidence intervals (CI)] comparing elevated CRP level (>3 mg/L) to low CRP level (<1 mg/L) was 3.12 (1.77-5.48), p-trend<0.0001. This association persisted in separate analysis among men and women. The results were consistent in subgroup analyses by categories of age, smoking, body mass index, and hypertension status. In nonparametric models, the positive association between serum CRP and diabetes mellitus appeared to be present across the full range of CRP, without any threshold effect. Higher serum high-sensitivity CRP levels are positively associated with diabetes mellitus in a sample of US non-Hispanic blacks. Inflammatory processes previously shown to be related to diabetes mellitus in other race-ethnicities may be involved in non-Hispanic blacks also.

Background and objectives Diabetic retinopathy is the main microvascular complication in diabetes mellitus and needs to be diagnosed early to prevent severe sight-threatening retinopathy. The purpose of this study was to quantify the retinal microvasculature pattern and analyze the influence of blood glucose level and the duration of diabetes mellitus on the retinal microvasculature. Methods Two groups were analyzed: patients with diabetes (N=26) and patients without diabetes, ie, controls (N=26). A quantitative semiautomated method analyzed retinal microvasculature. The diameters of arterioles and venules were measured. The total numbers of arterioles and venules were counted. The ratio of arteriole diameter to venule diameter was calculated. The retinal microvasculature pattern was related to clinical and biochemical parameters. Results Patients with diabetes exhibited larger venule diameters in the upper temporal quadrant of the retina compared to the lower temporal quadrant (124.85±38.03 µm vs 102.92±15.69 µm; P<0.01). Patients with diabetes for 5 or more years had larger venule diameters in the upper temporal quadrant than patients without diabetes (141.62±44.44 vs 112.58±32.11 µm; P<0.05). The degree of venodilation in the upper temporal quadrant was positively correlated with blood glucose level and the estimated duration of diabetes mellitus. Interpretation and conclusion The employed quantitative method demonstrated that patients with diabetes exhibited venule dilation in the upper temporal quadrant, and the duration of diabetes mellitus was positively correlated with blood glucose level. Therefore, the early assessment of retinal microvascular changes is possible prior to the onset of diabetic retinopathy. PMID:26345217

Objectives To determine the prevalence of type 2 diabetes mellitus, in three groups of Peruvian adults, using fasting glucose and glycosylated hemoglobin (A1C). Methodology/Principal Findings This study included adults from the PERU MIGRANT Study who had fasted ≥8 h. Fasting glucose ≥126 mg/dL and A1C≥6.5% were used, separately, to define diabetes. Subjects with a current diagnosis of diabetes were excluded. 964 of 988 subjects were included in this analysis. Overall, 0.9% (95%CI 0.3–1.5) and 3.5% (95%CI 2.4–4.7) had diabetes using fasting glucose and A1C criteria, respectively. Compared to those classified as having diabetes using fasting glucose, newly classified subjects with diabetes using A1C (n = 25), were older, poorer, thinner and more likely to come from rural areas. Of these, 40% (10/25) had impaired fasting glucose (IFG). Conclusions This study shows that the use of A1C as diagnostic criteria for type 2 diabetes mellitus identifies people of different characteristics than fasting glucose. In the PERU MIGRANT population using A1C to define diabetes tripled the prevalence; the increase was more marked among poorer and rural populations. More than half the newly diagnosed people with diabetes using A1C had normal fasting glucose. PMID:21464957

To investigate the effects of semiconductor laser acupoint irradiation on blood glucose, glycosylated hemoglobin and physical fitness in type 2 diabetes mellitus, 44 cases of type 2 diabetic patients were randomly divided into a control group and a treatment group. All patients in both groups were given a drug treatment. The Hegu, Quchi and Zusanli acupoints of patients in the treatment group were then irradiated daily for 15 d with a 10 MW semiconductor laser. Before and after treatment, patients in both groups underwent a variety of tests and measurements: a two-hour postprandial blood glucose test; a glycosylated hemoglobin test and body mass index (BMI), waist-to-hip ratio (WHR) and body fat percentage (BFP) measurements. The data detected after treatment greatly decreased in the treatment group and was significantly different from that in the control group. It is shown that the acupoint irradiation with a semiconductor laser can improve two-hour postprandial blood glucose, glycosylated hemoglobin and some physical fitness measurements in type 2 diabetes mellitus patients.

Diabetes mellitus is known to adversely affect the immune system. Immune dysfunction is also associated with the etiology of diabetes mellitus. Immune dysfunction is associated with diminished chemotactic, phagocytic and monocyte activity. There is also increased T-cell activity. All these are associated with acute hyperglycemia. We investigated the cellular arm of the immune system of patients with diabetes mellitus using intradermal reactions (IDR) to purified protein derivative (PPD). Both groups high blood glucose [HBG] vs. low blood glucose [LBG]) were homogeneous in terms of size and sex and average age (24. vs. 22.; 21 F vs 25 M; 56.5yrs. vs. 54.5 yrs.). The LBG had a greater average duration of diabetes (13.6 yrs vs. 9.3 yrs), which suggests an increased tendency to complications of diabetes mellitus. The results showed an average blood glucose and IDR (HBG vs. LBG) of 235.8 +/- 46.5 mg/dl vs. 144.3 +/- 26.7 mg/dl and 18.5 +/- 8.5 mm vs. 12.2 +/- 7.0 mm respectively. These results showed that IDR is significantly affected by hyperglycemia. This increased IDR may be a consequence of the synergy between interferon-gamma and tumor necrosis factor alpha which is a significant factor in diabetes. Also, there is an accentuation of this synergy following injection of PPD. It appears to be clear that IDR to PPD may be influenced by the diabetic state, especially acute hyperglycemia. However, it also appears that IDR to PPD may not be an adequate method for assessing cutaneous cell-mediated immunity.

Administration of antisomatotropin serum in diabetes mellitus.
Góth, M; Szabolcs, I
1981-03-01
The effect of antisomatotropin serum (ASS), raised in horse against human growth hormone, on the carbohydrate metabolism of diabetics has been investigated. Among the eight diabetic patients treated so far two had GH secreting pituitary adenoma, two insulin-dependent, and four others adult onset diabetes mellitus. The glucose tolerance curve improved in all but one patient. The effect lasted for two--four weeks. Because of this short time of efficiency, the place of ASS in the definite treatment of diabetes mellitus cannot been judged so far, however, its administration in diabetic retinopathy seems to be advantageous.

A murine model of type 2 diabetes mellitus was used to compare the antidiabetic effects of the dipeptidyl peptidase-4 (DPP4) inhibitor vildagliptin and biguanide, metformin. Swiss albino mice (n=20 males; n=25 females) were given high fat diet (HFD) ad libitum for 3weeks followed by low dose (40mgkg -1 body weight, bw daily) of streptozotocin (STZ) intraperitoneally five times from the 22nd day of treatment onwards, with HFD continued up to 26th day. Controls (n=15 males; n=15 females) were fed normal balanced diet without administration of STZ. Successful induction of diabetes mellitus was confirmed by testing for fasting blood glucose, intraperitoneal glucose tolerance and intraperitoneal insulin sensitivity. Diabetic mice were administered vildagliptin (10mgkg -1 bw daily) and metformin (50mgkg -1 bw daily) orally for 4weeks. Control, diabetic, vildagliptin and metformin-treated diabetic mice were evaluated for alterations in lipid profile using blood serum and histopathology and oxidative stress using tissues including liver, kidney and heart. Diabetic mice showed significant alterations in lipid profile, tissue histopathology, impaired glucose tolerance, lower insulin sensitivity and elevated lipid peroxidation and protein carbonylation, with depressed catalase activity, when compared to age and gender-matched controls. Metformin and vildagliptin ameliorated the abovementioned diabetic conditions, with vildagliptin found to be more effective. A murine model developed by the combination of HFD and multiple low dose of STZ mimics the metabolic characteristics of type 2 diabetes mellitus in humans, and may be useful for antidiabetic drug screening.

[Risk factors for changes in glucose metabolism in pregnancy].
Esparza, L; Tavano, L; Breña, H; Avila, H; Karchmer, S
1989-02-01
Eighty women were studied having between 20-25 weeks of gestation at the National Institute of Perinatology. Weight and height were taken, and they were questioned about the risk factors (positive family history of diabetes mellitus, age, overweight and number of gestations). Two hours postprandial glucose tests were carried out using 100 g glucose load. Plasma glucose values were determinated according to the glucose-oxidase technique. Results showed that 36% of the population had at least glucose metabolism alteration (GMA) (glucose value 120 mg/dL). No significant difference was found for the weeks of gestation, nor number of gestations to define any cut point. On the other hand, significant values were found for the other risk factors, such as being 35 years or older, having 119% and 103% or more of pregestational and gestational weight for height respectively and having positive maternal family history of diabetes mellitus. The risk factor that is more capable to identify the subjects with an GMA is age 35 years followed by positive maternal family history of diabetes mellitus; when the combination of 4 risk factors is observed (gestas factor is excluded because it is a confusion element), the pregestational and pregestational and gestational weights work more like secondary supplementary risk factors than like determinants of the metabolic process. In view of these facts, it was found that positive maternal history of diabetes mellitus and the age less than or equal to 35 years individually and the presence of 3-4 risk factors can be considered high risk characteristics to develop GMA.

Diabetes mellitus is becoming a big public health challenge, particularly in developing countries like Ethiopia. It is a manageable disease if early screening and follow up is made. However, as studies in Ethiopia are limited and unorganized, determining the magnitude of prediabetes and diabetes and identifying associated risk factors is quite essential. A community-based, cross-sectional study was conducted from February to April 2015 among adults (aged ≥20 years) in a rural Koladiba town. A multistage sampling technique was used to select a total of 392 study participants. Data were collected after a fully informed written consent was obtained from each participant. Demographic, behavioral, and clinical data were collected using a well-structured questionnaire. Multivariable logistic regression models were fitted to control the effect of confounders. Adjusted odds ratios (AOR) with their 95% confidence intervals (95% CI) were computed to measure associations. A p value of <0.05 was considered as statistically significant. The prevalence of impaired fasting glucose and undiagnosed diabetes mellitus were 12% (95% CI 9-16) and 2.3% (95% CI 1.1-4), respectively, in Koladiba. Overweight (AOR: 4.257, 95% CI 1.345-13.476), obesity (AOR: 5.26, 95% CI 1.138-24.316), hypertriglyceridemia (AOR: 2.83, 95% CI 1.451-5.521), and systolic hypertension (AOR: 3.858, 95% CI 1.62-9.189) were found to be independently associated with impaired fasting glucose. Positive family history of diabetes also showed a marginal association with impaired fasting glucose (p = 0.057). Male sex (p = 0.012) and hypertriglyceridemia (p = 0.030) were associated with undiagnosed diabetes mellitus. The prevalence of impaired fasting glucose and undiagnosed diabetes mellitus are found to be significant. Obesity, hypertriglyceridemia, and systolic hypertension are independently associated with impaired fasting glucose among adults. We recommend that the community be aware of healthy life style, early screening, and maintain continuous follow up.

This preliminary RCT investigated whether an integrated lifestyle modification program that focuses on reducing postprandial blood glucose through replacing high with low glycemic load foods and increasing routine physical activities guided by systematic self-monitoring of blood glucose (GEM) could improve metabolic control of adults with type 2 diabetes mellitus, without compromising other physiological parameters. Forty-seven adults (mean age 55.3 years) who were diagnosed with type 2 diabetes mellitus for less than 5 years (mean 2.1 years), had HbA1c ≥ 7% (mean 8.4%) and were not taking blood glucose lowering medications, were randomized to routine care or five 1-h instructional sessions of GEM. Assessments at baseline and 6 months included a physical exam, metabolic and lipid panels, and psychological questionnaires. The GEM intervention led to significant improvements in HbA1c (decreasing from 8.4 to 7.4% [69-57 mmol/mol] compared with 8.3 to 8.3% [68-68 mmol/mol] for routine care; Interaction p<.01) and psychological functioning without compromising other physiological parameters. Consistent with a patient-centered approach, GEM appears to be an effective lifestyle modification option for adults recently diagnosed with type 2 diabetes mellitus.

Continuous glucose monitoring (CGM) parameters, self-monitored blood glucose (SMBG), HbA1c and oral glucose tolerance test (OGTT) were studied during preclinical type 1 diabetes mellitus. Ten asymptomatic children with multiple (⩾2) islet autoantibodies (cases) and 10 age and sex-matched autoantibody-negative controls from the Type 1 Diabetes Prediction and Prevention (DIPP) Study were invited to 7-day CGM with Dexcom G4 Platinum Sensor. HbA1c and two daily SMBG values (morning and evening) were analyzed. Five-point OGTTs were performed and carbohydrate intake was assessed by food records. The matched pairs were compared with the paired sample t-test. The cases showed higher mean values and higher variation in glucose levels during CGM compared to the controls. The time spent ⩾7.8mmol/l was 5.8% in the cases compared to 0.4% in the controls (p=0.040). Postprandial CGM values were similar except after the dinner (6.6mmol/l in cases vs. 6.1mmol/l in controls; p=0.023). When analyzing the SMBG values higher mean level, higher evening levels, as well as higher variation were observed in the cases when compared to the controls. HbA1c was significantly higher in the cases [5.7% (39mmol/mol) vs. 5.3% (34mmol/mol); p=0.045]. No differences were observed in glucose or C-peptide levels during OGTT. Daily carbohydrate intake was slightly higher in the cases (254.2g vs. 217.7g; p=0.034). Glucose levels measured by CGM and SMBG are useful indicators of dysglycemia during preclinical type 1 diabetes mellitus. Increased evening glucose values seem to be common in children with preclinical type 1 diabetes mellitus. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

Glucose homeostasis is a vital and complex process, and its disruption can cause hyperglycaemia and type II diabetes mellitus. Glucokinase (GK), a key enzyme that regulates glucose homeostasis, converts glucose to glucose-6-phosphate in pancreatic β-cells, liver hepatocytes, specific hypothalamic neurons, and gut enterocytes. In hepatocytes, GK regulates glucose uptake and glycogen synthesis, suppresses glucose production, and is subject to the endogenous inhibitor GK regulatory protein (GKRP). During fasting, GKRP binds, inactivates and sequesters GK in the nucleus, which removes GK from the gluconeogenic process and prevents a futile cycle of glucose phosphorylation. Compounds that directly hyperactivate GK (GK activators) lower blood glucose levels and are being evaluated clinically as potential therapeutics for the treatment of type II diabetes mellitus. However, initial reports indicate that an increased risk of hypoglycaemia is associated with some GK activators. To mitigate the risk of hypoglycaemia, we sought to increase GK activity by blocking GKRP. Here we describe the identification of two potent small-molecule GK-GKRP disruptors (AMG-1694 and AMG-3969) that normalized blood glucose levels in several rodent models of diabetes. These compounds potently reversed the inhibitory effect of GKRP on GK activity and promoted GK translocation both in vitro (isolated hepatocytes) and in vivo (liver). A co-crystal structure of full-length human GKRP in complex with AMG-1694 revealed a previously unknown binding pocket in GKRP distinct from that of the phosphofructose-binding site. Furthermore, with AMG-1694 and AMG-3969 (but not GK activators), blood glucose lowering was restricted to diabetic and not normoglycaemic animals. These findings exploit a new cellular mechanism for lowering blood glucose levels with reduced potential for hypoglycaemic risk in patients with type II diabetes mellitus.

Diabetes mellitus is a chronic metabolic disease, characterized by high blood glucose levels, affecting millions of people around the world. Currently, the main treatment for diabetes requires multiple daily injections of insulin and self-monitoring of blood glucose levels, which markedly affect patients' quality of life. In this study we present a novel strategy for controlled and prolonged glucose regulation, based on the administration of insulin-coated gold nanoparticles (INS-GNPs). We show that both intravenous and subcutaneous injection of INS-GNPs into a mouse model of type 1 diabetes decreases blood glucose levels for periods over 3 times longer than free insulin. We further showed that conjugation of insulin to GNPs prevented its rapid degradation by the insulin-degrading-enzyme, and thus allows controlled and adjustable bio-activity. Moreover, we assessed different sizes and concentrations of INS-GNPs, and found that both parameters have a critical effect in vivo, enabling specific adjustment of blood glucose levels. These findings have the potential to improve patient compliance in diabetes mellitus.

[Islet transplantation in type II diabetes mellitus--model of the spontaneous diabetic Cohen rat].
Wiegand, S; Bretzel, R G; Cohen, A M; Federlin, K
1989-01-01
The spontaneous diabetic Cohen-rat is one of the few animal models of the diabetes mellitus Type II (NIDDM). A spontaneous diabetic animal line and a diabetes-resistant line originated from a parental lineage by genetic selection with regard to the glucose tolerance on condition of feeding of a saccharose-rich and copper-poor diet. In each case 1000 islets of the diabetes-resistant line were transplanted in 28 animals of the diabetic line. Body weight, blood-sugar concentration, glucosuria, glucose tolerance, and the HbA1 were normalized after the transplantation. The serum levels of insulin and glucagon increased. These results emphasize etiopathogenetic importance of the islets of Langerhans in this animal model.

The Danish National Birth Cohort (DNBC) contains comprehensive information on diet, lifestyle, constitutional and other major characteristics of women during pregnancy. It provides a unique source for studies on health consequences of gestational diabetes mellitus. Our aim was to identify and validate the gestational diabetes mellitus cases in the cohort. We extracted clinical information from hospital records for 1609 pregnancies included in the Danish National Birth Cohort with a diagnosis of diabetes during or before pregnancy registered in the Danish National Patient Register and/or from a Danish National Birth Cohort interview during pregnancy. We further validated the diagnosis of gestational diabetes mellitus in 2126 randomly selected pregnancies from the entire Danish National Birth Cohort. From the individual hospital records, an expert panel evaluated gestational diabetes mellitus status based on results from oral glucose tolerance tests, fasting blood glucose and Hb1c values, as well as diagnoses made by local obstetricians. The audit categorized 783 pregnancies as gestational diabetes mellitus, corresponding to 0.89% of the 87 792 pregnancies for which a pregnancy interview for self-reported diabetes in pregnancy was available. From the randomly selected group the combined information from register and interviews could correctly identify 96% (95% CI 80-99.9%) of all cases in the entire Danish National Birth Cohort population. Positive predictive value, however, was only 59% (56-61%). The combined use of data from register and interview provided a high sensitivity for gestational diabetes mellitus diagnosis. The low positive predictive value, however, suggests that systematic validation by hospital record review is essential not to underestimate the health consequences of gestational diabetes mellitus in future studies. © 2016 Nordic Federation of Societies of Obstetrics and Gynecology.

2015-01-01
Diabetes mellitus is a complex metabolic disorder that involves the small blood vessels, often causing widespread damage to tissues, including the eyes' optic refractive error. In patients with newly diagnosed diabetes mellitus who have unstable blood glucose levels, refraction may be incorrect. We aimed to investigate refraction in patients who were recently diagnosed with diabetes and treated at our centre. This prospective study was performed from February 2013 to January 2014. Patients were diagnosed with diabetes mellitus using laboratory biochemical tests and clinical examination. Venous fasting plasma glucose (fpg) levels were measured along with refractive errors. Two measurements were taken: initially and after four weeks. The last difference between the initial and end refractive measurements were evaluated. Our patients were 100 males and 30 females who had been newly diagnosed with type II DM. The refractive and fpg levels were measured twice in all patients. The average values of the initial measurements were as follows: fpg level, 415 mg/dl; average refractive value, +2.5 D (Dioptres). The average end of period measurements were fpg, 203 mg/dl; average refractive value, +0.75 D. There is a statistically significant difference between after four weeks measurements with initially measurements of fasting plasma glucose (fpg) levels (p<0.05) and there is a statistically significant relationship between changes in fpg changes with glasses ID (p<0.05) and the disappearance of blurred vision (to be greater than 50% success rate) were statistically significant (p<0.05). Also, were detected upon all these results the absence of any age and sex effects (p>0.05). Refractive error is affected in patients with newly diagnosed diabetes mellitus; therefore, plasma glucose levels should be considered in the selection of glasses.

Background and aims. The aim of this study was to establish a relationship between salivary glucose levels and Candida carriage rate in type 2 diabetes mellitus patients and assess the growth characteristics and acid production of Candida in glucose-supplemented saliva. Materials and methods . A total of 90 subjects, 30 with controlled type 2 diabetes, 30 with uncontrolled type 2 diabetes and 30 without diabetes (control subjects), aged 30‒60 years, participated in the study. Unstimulated saliva was collected and investigated for glucose levels (GOD-POD method), colony-forming units (CFU) of Candida and salivary pH, using Indikrom paper strips). Analysis of statistical significance of salivary glucose and PH levels was carried out using post hoc Tukey HSD test. Correlation of Candida carriage rate with salivary glucose and salivary PH in the study groups and control group was made using Pearson's correlation. Results. Candida CFUs were significantly higher in diabetic subjects, with a significant and positive correlation with salivary glucose levels. There was a negative correlation between salivary PH levels and Candida carriage rate. Conclusion. Increased salivary glucose was associated with increased prevalence of oral Candida in diabetic subjects. The growth of Candida in saliva was accompanied by a rapid decline in PH, which in turn favored their growth.

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.

Diabetes mellitus in a patient with glycogen storage disease type Ia: a case report.
Cohn, Aviva; Ohri, Anupam
2017-11-12
Glycogen storage disease type Ia is a genetic disorder that is associated with persistent fasting hypoglycemia and the inability to produce endogenous glucose. The development of diabetes with glycogen storage disease is exceedingly rare. The underlying pathogenesis for developing diabetes in these patients is unclear, and there are no guidelines for treatment. We describe a case of a 34-year-old woman of South Asian descent with glycogen storage disease type Ia, who developed uncontrolled diabetes mellitus as a young adult. Hyperglycemia was noted after childbirth, and worsened years later. Treatment for diabetes was difficult due to risks of hypoglycemia from her underlying glycogen storage disease. With minimal hypoglycemic events, the patient's blood glucose improved with exercise in combination with a sodium-glucose co-transporter 2 inhibitor and an alpha glucosidase inhibitor. We report a rare case of diabetes in the setting of glycogen storage disease-Ia. Based on the literature, there appears to be a relationship between glycogen storage disease and metabolic syndrome, which likely plays a role in the pathogenesis. The management of glycemic control remains a clinical challenge, requiring management of both fasting hypoglycemia from glycogen storage disease, as well as post-prandial hyperglycemia from diabetes mellitus.

Lipid Composition of Cell Membranes and Its Relevance in Type 2 Diabetes Mellitus
Weijers, Rob N.M.
2012-01-01
Identifying the causative relationship between the fatty acid composition of cell membranes and type 2 diabetes mellitus fundamentally contributes to the understanding of the basic pathophysiological mechanisms of the disease. Important outcomes of the reviewed studies appear to support the hypotheses that the flexibility of a membrane determined by the ratio of (poly)unsaturated to saturated fatty acyl chains of its phospholipids influences the effectiveness of glucose transport by insulin-independent glucose transporters (GLUTs) and the insulin-dependent GLUT4, and from the prediabetic stage on a shift from unsaturated towards saturated fatty acyl chains of membrane phospholipids directly induces a decrease in glucose effectiveness and insulin sensitivity. In addition, it has become evident that a concomitant increase in stiffness of both plasma and erythrocyte membranes may decrease the microcirculatory flow, leading ultimately to tissue hypoxia, insufficient tissue nutrition, and diabetes-specific microvascular pathology. As to the etiology of type 2 diabetes mellitus, a revised hypothesis that attempts to accommodate the reviewed findings is presented. PMID:22698081

This study was designed to investigate the clinical predictors of abnormal glucose tolerance 5-7 weeks after delivery. Subjects were 155 women diagnosed with gestational diabetes mellitus (GDM) between October 2005 and September 2013 whose pregnancy and delivery were managed at our center. Subjects were divided into a normal glucose tolerance group (NGT; n = 113), or abnormal glucose tolerance group (AGT; n = 42) with borderline or overt diabetes mellitus, based on 75-g oral glucose tolerance test (75 gOGTT) results 5-7 weeks after delivery. We extracted profiles by which abnormal glucose tolerance levels 5-7 weeks after delivery were predicted using a classification and regression tree (CART) from parameters measured at the time of GDM diagnosis. Logistic regression analysis was used to determine prediction accuracy. Subjects with fasting plasma glucose (FPG) ≥92 mg/dL and immuno-reactive insulin level <100 μU/mL 60 min after load (IRI60min) at time of diagnosis showed a significantly higher risk of developing abnormal glucose tolerance 5-7 weeks after delivery than subjects with FPG <92 mg/dL (p < 0.0001). Subjects with FPG ≥92 mg/dL and IRI60min ≥ 100 μU/mL had the same risk as those with FPG of <92 mg/dL. Patients with gestational diabetes who met the criteria specified above at diagnosis were at a higher risk of developing diabetes mellitus in the future. By explaining this issue to patients, we expect to improve the rate of postpartum follow-up. This should facilitate early detection of diabetes, and help prevent associated complications.

It is shown that glucocorticoids have discordant effects on plasma glucose concentration through their effects on hepatic glycogen deposition, gluconeogenesis and peripheral insulin resistance. Cushing's syndrome caused by cortisol overproduction is frequently accompanied with diabetes mellitus, but fasting plasma glucose (FPG) and post-glucose load plasma glucose levels are not examined in patients with Cushing's syndrome. The aim of this study was to investigate FPG, HbA1c and oral glucose tolerance test (OGTT) 2-h PG and their relationship in patients with Cushing's syndrome, in comparison with control subjects. Sixteen patients with Cushing's syndrome (ACTH-dependent 31%, ACTH-independent 69% and diabetes mellitus 50%) and 64 controls (32 patients with type 2 diabetes mellitus and 32 non-diabetic subjects matched for age, sex and BMI) were enrolled in this study. HbA1c and FPG in the patients with Cushing's syndrome were not different from the controls, whereas the FPG/HbA1c ratio was significantly lower in the patients with Cushing's syndrome than the controls. OGTT 2-h PG was significantly higher in the non-diabetic patients with Cushing's syndrome than the non-diabetic controls, while HbA1c was not different between both groups and FPG was significantly lower in the patients with Cushing's syndrome than the controls. HOMA-β but not HOMA-R was significantly higher in the patients with Cushing's syndrome than the controls. In conclusion, FPG was rather lower in the patients with Cushing's syndrome than the controls. Postprandial PG or post-glucose loaded PG, but not FPG, is useful to evaluate the abnormality of glucose metabolism in patients with Cushing's syndrome.

Elevated 2-h plasma glucose concentration (2 h-PG) during a 75 g OGTT predict the development of type 2 diabetes mellitus. However, 1-h plasma glucose concentration (1 h-PG) is associated with insulin secretion and may be a better predictor of type 2 diabetes. We aimed to investigate the association between 1 h-PG and 2 h-PG using gold standard methods for measuring insulin secretion and action. We also compared 1 h-PG and 2 h-PG as predictors of type 2 diabetes mellitus. This analysis included adult volunteers without diabetes, predominantly Native Americans of Southwestern heritage, who were involved in a longitudinal epidemiological study from 1965 to 2007, with a baseline OGTT that included measurement of 1 h-PG. Group 1 (n = 716) underwent an IVGTT and hyperinsulinaemic-euglycaemic clamp for measurement of acute insulin response (AIR) and insulin-stimulated glucose disposal (M), respectively. Some members of Group 1 (n = 490 of 716) and members of a second, larger, group (Group 2; n = 1946) were followed-up to assess the development of type 2 diabetes (median 9.0 and 12.8 years follow-up, respectively). Compared with 2 h-PG (r = -0.281), 1 h-PG (r = -0.384) was more closely associated with AIR, whereas, compared with 1 h-PG (r = -0.340), 2 h-PG (r = -0.408) was more closely associated with M. Measures of 1 h-PG and 2 h-PG had similar abilities to predict type 2 diabetes, which did not change when both were included in the model. A 1 h-PG cut-off of 9.3 mmol/l provided similar levels of sensitivity and specificity as a 2 h-PG cut-off of 7.8 mmol/l; the latter is used to define impaired glucose tolerance, a recognised predictor of type 2 diabetes mellitus. The 1 h-PG was associated with important physiological predictors of type 2 diabetes and was as effective as 2 h-PG for predicting type 2 diabetes mellitus. The 1 h-PG is, therefore, an alternative method of identifying individuals with an elevated risk of type 2 diabetes mellitus.

About 30-50% of the world human population are infected with the protozoan parasite Toxoplasma gondii (Nicolle et Manceaux, 1908). Latent toxoplasmosis has many specific behavioural and physiological effects on the human body and influences the course of pregnancy, including secondary sex ratio of children of infected mothers. It was suggested that an increased concentration of glucose could be the proximate cause of increased sex ratio. There are some indirect indications of possible association between toxoplasmosis and certain forms of diabetes. Here we searched for a possible link between latent toxoplasmosis and the level of glucose in the blood. In a cross-sectional study, we found that pregnant women with latent toxoplasmosis had significantly higher blood glucose levels during the oral glucose tolerance test (n = 191, p = 0.010; the level of fasting plasma glucose: mean = 5.04 mmol/l vs mean = 4.88 mmol/l; blood glucose level at 1 hour mean = 7.73 mmol/l vs mean = 6.89 mmol/l and blood glucose level at two hours mean = 6.43 mmol/l vs mean = 5.74 mmol/l) and higher prevalence (19.5 %) of gestational diabetes mellitus (n = 532, p = 0.033, odds ratio = 1.78) in the 24-28th gestational weeks than T. gondii-free women (12.0 %). Increased level of glucose and increased incidence of gestational diabetes mellitus could have considerable clinical impact as contributors to the development of the metabolic syndrome and type 2 diabetes in T. gondii-infected women. Our results also brought the first empirical support for the hypothesis that the glucose concentration may play a role in T. gondii-associated offspring sex ratio shifts.

Diabetes mellitus in a toco toucan.
Douglass, E M
1981-04-01
Diabetes mellitus is rarely diagnosed in avian species. The majority of reported cases have occurred in small birds, such as the parakeet and canary. A major complicating factor in the diagnosis of diabetes in birds is the lack of accepted normal blood glucose values, which can be highly variable among avian species. In the case to be reported here a Toco Toucan (Ramphastos toco) was affected. The diagnosis of diabetes mellitus in this instance was based on the history, clinical signs, and response to therapy.

Oxidative stress is manifested in embryos exposed to maternal diabetes mellitus, yet specific mechanisms for diabetes mellitus-induced heart defects are not defined. Gene deletion of intermediates of Wingless-related integration (Wnt) signaling causes heart defects similar to those observed in embryos from diabetic pregnancies. We tested the hypothesis that diabetes mellitus-induced oxidative stress impairs Wnt signaling, thereby causing heart defects, and that these defects can be rescued by transgenic overexpression of the reactive oxygen species scavenger superoxide dismutase 1 (SOD1). Wild-type (WT) and SOD1-overexpressing embryos from nondiabetic WT control dams and nondiabetic/diabetic WT female mice mated with SOD1 transgenic male mice were analyzed. No heart defects were observed in WT and SOD1 embryos under nondiabetic conditions. WT embryos of diabetic dams had a 26% incidence of cardiac outlet defects that were suppressed by SOD1 overexpression. Insulin treatment reduced blood glucose levels and heart defects. Diabetes mellitus increased superoxide production, canonical Wnt antagonist expression, caspase activation, and apoptosis and suppressed cell proliferation. Diabetes mellitus suppressed Wnt signaling intermediates and Wnt target gene expression in the embryonic heart, each of which were reversed by SOD1 overexpression. Hydrogen peroxide and peroxynitrite mimicked the inhibitory effect of high glucose on Wnt signaling, which was abolished by the SOD1 mimetic, tempol. The oxidative stress of diabetes mellitus impairs Wnt signaling and causes cardiac outlet defects that are rescued by SOD1 overexpression. This suggests that targeting of components of the Wnt5a signaling pathway may be a viable strategy for suppression of congenital heart defects in fetuses of diabetic pregnancies. © 2015 American Heart Association, Inc.

Diabetes mellitus and hypertension: a dual threat.
Oktay, Ahmet Afşin; Akturk, Halis Kaan; Jahangir, Eiman
2016-07-01
The following is a review of the current concepts on the relationship between hypertension (HTN) and diabetes mellitus with a focus on the epidemiology and cardiovascular prognostic implications of coexistent HTN and diabetes mellitus, shared mechanisms underlying both conditions and pathophysiology of increased risk of cardiovascular disease, treatment of HTN in individuals with diabetes mellitus, and effects of anti-diabetic medications on blood pressure (BP). Diabetes mellitus and HTN often coexist in the same individual. They share numerous risk factors and underlying pathophysiologic mechanisms, most important of which are insulin resistance and inappropriate activation of the rennin-angiotensin-aldosterone system. Recently updated guidelines recommend a BP goal of 140/90 mmHg in most individuals with diabetes mellitus. A new class of anti-diabetic medications, sodium-glucose co-transporter 2 inhibitors, has shown favorable effects on BP. HTN affects the majority of individuals with diabetes mellitus. Coexistence of diabetes mellitus and HTN, especially if BP is not well controlled, dramatically increases the risk of morbidity and mortality from cardiovascular disease. BP control is an essential part of management of patients with diabetes mellitus, because it is one of the most effective ways to prevent vascular complications and death.

Non-alcoholic fatty liver disease (NAFLD) is a form of clinical syndrome characterized by the fatty degeneration in liver histology and should be further investigated. The aim of the study was to investigate the effects of blood glucose, serum chemerin and insulin resistance on non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes mellitus to provide a basis for the prevention and treatment thereof. In total, 300 patients with type 2 diabetes mellitus treated and admitted into the Endocrinology Department of our hospital from June 2015 to June 2017 were enrolled and divided into the simple type 2 diabetes mellitus (group A) and concurrent NAFLD (group B) groups. The sex, age, body mass index (BMI), blood pressure, blood biochemical indexes and chemerin level were compared between the two groups. The patients in group B were further divided into the mild fatty liver (group B1), moderate fatty liver (group B2) and severe fatty liver (group B3) groups. The sex, age, BMI blood pressure, blood biochemical indexes and chemerin level were also compared among the three groups. Finally, the risk factors of type 2 diabetes mellitus complicated by NAFLD were analyzed via logistic regression. The BMI, fasting plasma glucose (FPG), 2 h post-prandial plasma glucose (2hPG), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-c), alanine aminotransferase (ALT), fasting insulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR) and HOMA-β indexes and serum chemerin level in group B were significantly higher than those in group A (P<0.05 or P<0.01). Notably, the aggravation of NAFLD, the aforementioned indexes were obviously increased (P<0.05 or P<0.01). The regression analysis revealed that BMI, FPG, TC, LDL-c, FINS, HOMA-IR and chemerin were risk factors of concurrent NAFLD. Thus, type 2 diabetes mellitus complicated by NAFLD is closely associated with severe glucose-lipid metabolism disorder and insulin resistance, and BMI, FPG, TC, LDL-c, FINS, HOMA-IR and chemerin constitute risk factors of concurrent NAFLD.

Saliva is a unique fluid, which is important for normal functioning of the oral cavity. Diabetes mellitus (DM) is a disease of absolute or relative insulin deficiency characterized by insufficient secretion of insulin by pancreatic beta-cells. The diagnosis of diabetes through blood is difficult in children, older adults, debilitated and chronically ill patients, so diagnosis by analysis of saliva can be potentially valuable as collection of saliva is noninvasive, easier and technically insensitive, unlike blood. The aim of the study was to correlate blood glucose level (BGL) and salivary glucose level (SGL) in DM patients. A cross-sectional study was conducted in 120 patients, who were categorized as 40 controlled diabetics, 40 uncontrolled diabetics and 40 healthy, age- and sex-matched individuals constituted the controls. The blood and unstimulated saliva samples were collected from the patients at the different intervals for fasting, random and postprandial levels. These samples were then subjected for analysis of glucose in blood and saliva using glucose oxidase/peroxidase reagent in HITACHI 902 (R) Automatic analyzer, and the results were recorded. The mean SGLs were higher in uncontrolled and controlled diabetic groups than in nondiabetic group. A highly statistically significant correlation was found between fasting saliva glucose and fasting blood glucose in all the groups. With increase in BGL, increase in SGL was observed in patients with diabetes suggesting that SGL can be used for monitoring glycemic level in DM.

This study was carried to ascertain whether stress responses are associated with abnormalities in glucose tolerance, insulin sensitivity and pancreatic beta cell function and risk of type 2 Diabetes Mellitus. Salivary cortisol, a marker of hypothalamic-pituitary-adrenal (HPA) axis and salivary α-amylase, a marker of sympathetic nervous system (SNS) were compared in 125 subjects of newly detected diabetes mellitus (NDDM) and normal glucose tolerance (NGT) subjects who were diagnosed on the basis of oral glucose tolerance test (OGTT). Assessment of stress in them was done through stress scales - presumptive stressful life events scale (PSLES), perceived stress scale (PSS) and sense of coherence (SOC) and correlated with these and other stress response markers. Significantly higher 10 pm salivary cortisol and post dexamethasone salivary cortisol were found in NDDM subjects as compared to NGT. 10 pm salivary cortisol correlated significantly with fasting plasma glucose (FPG), 2 h plasma glucose (2h PG) and glycated hemoglobin (HbA1c) while post dex salivary cortisol correlated with 2h PG, HbA1c and salivary α-amylase with 2h PG. Stepwise logistic regression analysis showed that body mass index (OR: 1.840), SOC (OR: 0.688) and 10 pm salivary cortisol (OR: 1.427) were the strongest predictors of NDDM. The results of the present study indicate that NDDM subjects display significantly higher chronic stress and stress responses when compared to subjects with NGT. Chronic stress and endocrine stress responses are significantly associated with glucose intolerance, insulin resistance and diabetes mellitus.

The implications of using Hemoglobin A1C for diagnosing Diabetes Mellitus
Malkani, Samir; Mordes, John P
2011-01-01
Until 2010 the diagnosis of diabetes mellitus was based solely on glucose concentration, but American Diabetes Association (ADA) recommendations now include a new criterion: hemoglobin A1C ≥6.5%. Because this change may have significant implications for diabetes diagnosis, we conducted a comprehensive literature review including peer-reviewed articles not referenced in the ADA report. We conclude that A1C and plasma glucose tests are frequently discordant for diagnosing diabetes. A1C ≥6.5% identifies fewer individuals as having diabetes than glucose-based criteria. Convenience of A1C test might increase the number of patients diagnosed, but this is unproven. Diagnostic cut-points for both glucose and A1C are based on consensus judgments regarding optimal sensitivity and specificity for the complications of hyperglycemia. A1C may not accurately reflect levels of glycemia in some situations, but in comparison with glucose measurements, it has greater analytic stability and less temporal variability. When choosing a diagnostic test for diabetes, the limitations of each choice must be understood. Clinical judgment and consideration of patient preference are required to appropriately select among the diagnostic alternatives. PMID:21531226

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 understand the situation and efficacy of community-based management programs on hypertension and type 2 diabetes mellitus patients in primary health service centers. In eight provinces being selected, a stratified multistage random sampling method was used to survey 5 116 cases of hypertension patients and 3 586 cases of type 2 diabetes mellitus patients aged over 35 years who had been under the management program for over 1 year. Face-to-face questionnaire interview and physical and biochemical examination were applied to collect related information, blood pressure and situation of glucose control. The rates of management on hypertension patients and type 2 diabetes mellitus patients were 23.6% (urban:17.1%, rural:28.1%, χ² = 27 195.33, P < 0.001)and 19.1% (urban:14.1%, rural:23.8%, χ² = 7 423.67, P < 0.001)while the standardized management rates were 61.1% (urban:63.3%, rural:58.6%, χ² = 11.82, P < 0.001)and 59.0% (urban:61.5%, rural:55.6%, χ² = 12.66, P < 0.001), respectively. Rate on blood pressure control among hypertension patients and the rate on fasting glucose control on type 2 diabetes mellitus patients were 50.3% (urban:62.0%, rural:36.6%, χ² = 329.31, P < 0.001)and 53.9% (urban:60.8%, rural:44.7%, χ² = 90.53, P < 0.001), respectively. Satisfaction rates for the management service of the hypertension patients and type 2 diabetes mellitus patients were 83.0% (urban:84.7% , rural: 80.7% , χ² = 13.42, P < 0.001) and 84.5% (urban:88.0% , rural:79.5% , χ² = 43.90, P < 0.001), respectively. Efficiency was achieved to some extent in managing hypertension and type 2 diabetes mellitus patients in primary health service centers. Further improvement was expected on rates regarding management, standardized management and control on both blood pressure and glucose.

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 <1.1. Decision-curve analysis showed that combining insulinogenic index/fasting immunoreactive insulin <1.1 with basic clinical information resulted in superior net benefits for prediction of postpartum glucose 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. © 2018 Diabetes UK.

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 < .00001) and HOMA-IR (Std. mean difference = -1.12; 95% CI = -2.05 to -0.18; p = .02), but showed no substantial impact on fasting plasma glucose (Std. mean difference = -0.49; 95% CI = -1.05-0.08; p = .09), 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 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.

Focusing on cardiovascular disease in type 2 diabetes mellitus: an introduction to bromocriptine QR.
Bell, David S
2012-09-01
Cardiovascular risk reduction is a key priority in patients with diabetes. The relationship between glycemic control and macrovascular outcomes, such as the benefit of intensive glucose control and the importance of postprandial or fasting blood glucose, is still under debate. A number of pharmacologic options are available to treat type 2 diabetes mellitus and these options have differing evidence for their cardiovascular safety. In this article, the novel agent bromocriptine quick release is discussed. Recently approved, this once-daily treatment provides glycemic control as monotherapy or in combination with other antihyperglycemic medications and has been shown in a prospective phase 3 safety study to not increase cardiovascular risk. Therefore, bromocriptine quick release increases the range of options available to treat patients with type 2 diabetes mellitus without increasing cardiovascular risk.

The role of long non-coding RNA in diabetic retinopathy, a serious complication of diabetes mellitus, has attracted increasing attention in recent years. The purpose of this study was to explore whether long non-coding RNA nuclear paraspeckle assembly transcript 1 was involved in the context of diabetic retinopathy and its underlying mechanisms. Our results revealed that nuclear paraspeckle assembly transcript 1 was significantly downregulated in the retina of diabetes mellitus rats. Meanwhile, miR-497 was significantly increased in diabetes mellitus rats' retina and high glucose-treated Müller cells, but brain-derived neurotrophic factor was increased. We also found that high glucose-induced apoptosis of Müller cells was accompanied by the significant downregulation of nuclear paraspeckle assembly transcript 1 in vitro. Further study demonstrated that high glucose-promoted Müller cells apoptosis through downregulating nuclear paraspeckle assembly transcript 1 and downregulated nuclear paraspeckle assembly transcript 1 mediated this effect via negative regulating miR-497. Moreover, brain-derived neurotrophic factor was negatively regulated by miR-497 and associated with the apoptosis of Müller cells under high glucose. Our results suggested that under diabetic conditions, downregulated nuclear paraspeckle assembly transcript 1 decreased the expression of brain-derived neurotrophic factor through elevating miR-497, thereby promoting Müller cells apoptosis and aggravating diabetic retinopathy.

Insulin analogues in type 1 diabetes mellitus: getting better all the time.
Mathieu, Chantal; Gillard, Pieter; Benhalima, Katrien
2017-07-01
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.

Improved cerebral energetics and ketone body metabolism in db/db mice
Andersen, Jens V; Christensen, Sofie K; Nissen, Jakob D
2016-01-01
It is becoming evident that type 2 diabetes mellitus is affecting brain energy metabolism. The importance of alternative substrates for the brain in type 2 diabetes mellitus is poorly understood. The aim of this study was to investigate whether ketone bodies are relevant candidates to compensate for cerebral glucose hypometabolism and unravel the functionality of cerebral mitochondria in type 2 diabetes mellitus. Acutely isolated cerebral cortical and hippocampal slices of db/db mice were incubated in media containing [U-13C]glucose, [1,2-13C]acetate or [U-13C]β-hydroxybutyrate and tissue extracts were analysed by mass spectrometry. Oxygen consumption and ATP synthesis of brain mitochondria of db/db mice were assessed by Seahorse XFe96 and luciferin-luciferase assay, respectively. Glucose hypometabolism was observed for both cerebral cortical and hippocampal slices of db/db mice. Significant increased metabolism of [1,2-13C]acetate and [U-13C]β-hydroxybutyrate was observed for hippocampal slices of db/db mice. Furthermore, brain mitochondria of db/db mice exhibited elevated oxygen consumption and ATP synthesis rate. This study provides evidence of several changes in brain energy metabolism in type 2 diabetes mellitus. The increased hippocampal ketone body utilization and improved mitochondrial function in db/db mice, may act as adaptive mechanisms in order to maintain cerebral energetics during hampered glucose metabolism.

Our study was a case-control cross-sectional study that was conducted on 20 children and adolescents suffering from type 1 diabetes mellitus and ten healthy non-diabetic children and adolescents serving as controls. The mean age of patients was 10.95 years. Oral sugar tolerance tests using glucose, sucrose and honey and measurement of fasting and postprandial serum C-peptide levels were done for all subjects in three separate sittings. The glycemic index (GI) and the peak incremental index (PII) were then calculated for each subject. Honey, compared to sucrose, had lower GI and PII in both patients (P < 0.001) and control (P < 0.05) groups. In the patients group, the increase in the level of C-peptide after using honey was not significant when compared with using either glucose or sucrose. However, in the control group, honey produced a significant higher C-peptide level, when compared with either glucose or sucrose. In conclusion, honey, because of its lower GI and PII when compared with sucrose, may be used as a sugar substitute in patients with type 1 diabetes mellitus.

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. All studies reported that complications or other adverse events were either similar or reduced with exercise. Aerobic or resistance exercise, performed at a moderate intensity at least three times per week, safely helps to control postprandial blood glucose levels and other measures of glycaemic control in women diagnosed with gestational diabetes mellitus.

Glucose-6-phosphatase is a key enzyme of glucose metabolic pathways. Deficiency of this enzyme leads to glycogen storage disease. This enzyme also plays a negative role in diabetes mellitus disorder in which the catalytic activity of this enzyme increases. Thus there is need for activators to enhance the activity of glucose-6-phosphatase in glycogen storage disease of type 1b while in diabetes mellitus repressors are needed to reduce its activity. Crude extracts of apricot, fig, mulberry and apple fruits were investigated for their repressive/enhancive effects on glucose-6-phosphatase in vivo. Albino mice were used as experimental animal. All the selected extracts showed depressive effects on glucose-6-phosphatase, which shows that all these extracts can be used as antidiabetic supplement of food. The inhibitory pattern was competitive one, which was evident from the effect of increasing dose from 1g/Kg body weight to 3g/Kg body weight for all the selected fruit extracts. However fig and apple fruit extracts showed high repressive effects for high doses as compared to apricot and mulberry fruit extracts. None of these selected fruit extracts showed enhancive effect on glucose-6-phosphatase activity. All these fruits or their extracts can be used as antidiabetic dietary supplement for diabetes mellitus.

SGLT2 inhibitors to control glycemia in type 2 diabetes mellitus: a new approach to an old problem.
Jabbour, Serge A
2014-01-01
Sodium-glucose cotransporter 2 (SGLT2) inhibitors are a new class of antidiabetic agents with a novel insulin-independent mechanism of action. The SGLT2 is a transporter found in the proximal tubule of the kidney and is responsible for approximately 90% of renal glucose reabsorption. The SGLT2 inhibitors reduce reabsorption of glucose in the kidney, resulting in glucose excretion in the urine (50-90 g of ~180 g filtered by the kidneys daily), which in turn lowers plasma glucose levels in people with diabetes. The insulin-independent mechanism of action of SGLT2 inhibitors dictates that they are associated with a very low risk of hypoglycemia and can be used in patients with any degree of β-cell function or insulin sensitivity. Clinical trials have shown that SGLT2 inhibitors are effective at reducing blood glucose levels, body weight, and blood pressure when used as monotherapy or in combination with other antidiabetic agents in patients with type 2 diabetes mellitus. Treatment with SGLT2 inhibitors is generally well tolerated, although these agents have been associated with an increased incidence of genital infections. The SGLT2 inhibitors have become a valuable addition to the armory of drugs used to treat patients with type 2 diabetes mellitus, and several agents within the class are currently under investigation in phase III clinical trials.

Diabetes Mellitus Associated with Epidemic of Infectious Hepatitis in Nigeria
Adi, F. C.
1974-01-01
This report concerns nine cases of diabetes mellitus associated with infectious hepatitis, an epidemic of which swept through eastern Nigeria between 1970 and 1972. All the patients showed the classical symptoms and signs of diabetes. They quickly responded to treatment, and after a few months the diabetes completely disappeared. Corticosteroid-glucose tolerance tests in four patients 12 to 30 months after the remission of their diabetes were normal. Contact with the remaining five patients had been lost a few months after clinical remission of their diabetes. The infectious hepatitis virus may have damaged pancreatic islet cells to cause an acute remittant form of diabetes mellitus. PMID:4811847

Metrics for glycaemic control - from HbA1c to continuous glucose monitoring.
Kovatchev, Boris P
2017-07-01
As intensive treatment to lower levels of HbA 1c characteristically results in an increased risk of hypoglycaemia, patients with diabetes mellitus face a life-long optimization problem to reduce average levels of glycaemia and postprandial hyperglycaemia while simultaneously avoiding hypoglycaemia. This optimization can only be achieved in the context of lowering glucose variability. In this Review, I discuss topics that are related to the assessment, quantification and optimal control of glucose fluctuations in diabetes mellitus. I focus on markers of average glycaemia and the utility and/or shortcomings of HbA 1c as a 'gold-standard' metric of glycaemic control; the notion that glucose variability is characterized by two principal dimensions, amplitude and time; measures of glucose variability that are based on either self-monitoring of blood glucose data or continuous glucose monitoring (CGM); and the control of average glycaemia and glucose variability through the use of pharmacological agents or closed-loop control systems commonly referred to as the 'artificial pancreas'. I conclude that HbA 1c and the various available metrics of glucose variability reflect the management of diabetes mellitus on different timescales, ranging from months (for HbA 1c ) to minutes (for CGM). Comprehensive assessment of the dynamics of glycaemic fluctuations is therefore crucial for providing accurate and complete information to the patient, physician, automated decision-support or artificial-pancreas system.

Previous data suggest that apelin and visfatin play a role in metabolism and glucose homeostasis. The aim of the present study was to determine differences in plasma apelin and visfatin concentrations between healthy subjects and patients with type 1 diabetes mellitus and to study the effect of hyperglycemia and insulin administration on their levels in patients with type 1 diabetes mellitus. One hundred patients with T1DM and 52 healthy subjects were examined. Nine patients with type 1 diabetes and 9 controls participated in a further study. In the main study, blood samples were taken after a 12-hour fast. In a further study, an oral glucose tolerance test was performed on two occasions. In session A, at baseline, insulin lispro (7 units) was administered subcutaneously to the type 1 diabetic patients, while a placebo injection was administered to controls. In session B, no insulin or placebo was administered. Apelin, visfatin, insulin and glucose levels were measured at baseline and 10, 20, 30, 60, 90, 120, 150 and 180 min after glucose consumption. Fasting plasma apelin concentrations were higher (p<0.001), while fasting visfatin levels tended to be lower (p=0.06) in patients with type 1 diabetes in comparison to healthy subjects. In the diabetes group, fasting apelin (but not visfatin) correlated with HDL-C (p=0.001). Apelin and visfatin did not change significantly during the oral glucose tolerance test in either group with or without exogenous insulin administration.

To test whether average long-term glucose exposure is associated with cognitive and physical function in middle-aged and younger-old adults with type 2 diabetes mellitus. Prospective cohort study. Data obtained as part of the Action for Health in Diabetes (Look AHEAD) trial (NCT00017953) and Look AHEAD Movement and Memory ancillary study (NCT01410097). Overweight and obese individuals with type 2 diabetes mellitus aged 45 to 76 at baseline (N = 879). Glycosylated hemoglobin (HbA1c) was measured at regular intervals over 7 years, and objective measures of cognitive function (Trail-Making Test, Modified Stroop Color-Word Test, Digit Symbol-Coding, Rey Auditory Verbal Learning Test, Modified Mini-Mental State Examination) and physical function (Short Physical Performance Battery, expanded Physical Performance Battery, 400-m and 20-m gait speed) and strength (grip and knee extensor strength) were assessed at the Year 8 or 9 follow-up examination. Average HbA1c exposure was 7.0 ± 1.1% (53 ± 11.6 mmol/mol), with 57% of participants classified as having HbA1c levels of less than 7% (<53 mmol/mol), 27% having levels of 7% to 8% (53-64 mmol/mol), and 16% having levels of greater than 8% (>64 mmol/mol). After adjustment for age, sex, race, education, smoking status, alcohol intake, knee pain, physical fitness, body mass index, diabetes mellitus medication and statin use, ancillary year visit, and study arm and site, higher HbA1c was associated with worse physical but not cognitive function. Further adjustment for prevalent diabetes mellitus-related comorbidities made all associations nonsignificant. Results did not differ when stratified according to participant baseline age (<60 vs ≥ 60). Results presented here suggest that, in the absence of diabetes mellitus-related complications, longitudinal glucose exposure is not associated with future cognitive and physical function. Optimal management of diabetes mellitus-related comorbidities may prevent or reduce the burden of disability associated with type 2 diabetes mellitus. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

It is unknown to what extent diabetes mellitus modifies the long-term risk of aseptic loosening in total hip arthroplasty (THA) and total knee arthroplasty (TKA). We examined the association between diabetes mellitus, perioperative hyperglycemia, and the likelihood of revisions for aseptic loosening. We studied 16,085 primary THA and TKA procedures performed at a large tertiary care hospital between 2002 and 2009. All blood glucose values around the time of surgery (within 1 week) were retrieved. Subsequent revision surgeries and the reasons for revision were ascertained through the institutional joint registry. Multivariate Cox models were used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) for aseptic loosening associated with diabetes mellitus and hyperglycemia adjusting for age, gender, body mass index, and surgery type. A total of 2911 (18%) surgeries had a diagnosis of diabetes mellitus at the time of surgery. Glucose testing was performed at least once in 7055 (44%) procedures within ±1 week of surgery. Although diabetic patients did not experience a higher risk of revision for aseptic loosening (HR, 0.87; 95% CI, 0.55-1.38), higher preoperative glucose values on the day before surgery were significantly associated with both the overall risk of revisions (HR, 2.80; 95% CI, 1.00-7.85) and revisions for aseptic loosening (HR, 4.95; 95% CI, 1.26-19.54). High preoperative hyperglycemia is a potential risk factor for aseptic loosening in THA and TKA. Copyright © 2017 Elsevier Inc. All rights reserved.

The purpose of this research was to evaluate the efficacy of a combination herbal product that is traditionally used for managing diabetes mellitus. Herbal drug contains Curcuma longa and Eugenia jambolanain the ratio of 1:1. It was orally administered at the dose of 1082 mg/70 kg twice a day for a period of 6 weeks to alloxan induced diabetic rats and compared with glibenclamide (standard). The effects of drug were observed at intervals, with respect to random and fasting glucose levels. HbA1C was also monitored after the drug treatment to monitor the overall diabetic effect. Results revealed that the combination of two herbs significantly reduced fasting and random glucose levels with HbA1C of less than 6% (p<0.001) in comparison to diabetic control. The control of fasting blood glucose levels by herbal combination is similar to the standard drug, glibenclamide (p<0.05). Random glucose levels by herbal combination is better than standard drug after one week and six weeks of treatment (p<0.01 and p<0.001 respectively) and similar after third week of treatment (p<0.05). Also, herbal drug combination showed HbA1C closer to the standard drug. It shows that this herbal combination can be of potential benefit in managing diabetes mellitus in future.

[Surgery for diabetes type 2?].
Müller, Markus K; Nocito, A; Schiesser, M
2010-02-17
Diabetes mellitus type 2 is a chronic disease with increasing prevalence in western society. Obesity represents a well established risk factor for the development of diabetes mellitus type 2. Several studies on surgical procedures for the treatment of obesity have shown a postoperative reduction of obesity-related co-morbidities. Thus, diabetes mellitus type 2 was shown to resolve or improve in more than 75% of morbidly obese patients (BMI >35) after bariatric surgery. These insights paved the way for the advent of metabolic surgery - a novel field with the goal to improve glucose metabolism in patients with a BMI of less than 35. Encouraging results from mostly observational studies have sparked the interest in the surgical management of diabetes mellitus type 2.

Introduction The prevalence, disease progression, and treatment outcomes for patients with type 2 diabetes vary significantly between ethnic groups. The Bihari community constitutes one of the most vulnerable populations in Bangladesh on the basis of access to health services and other fundamental rights. Our study aimed at finding out the prevalence and risk factors of type 2 diabetes among the Bihari adults in Dhaka city. Methods This cross-sectional community-based study was carried out among stranded Pakistanis (known as Bihari) living in camps in the Mirpur area from July 2014 to June 2015. Laboratory-based oral glucose tolerance test (OGTT) was the basis for the diagnosis of type 2 diabetes mellitus (DM). Anthropometric measurements, blood pressure, biochemical tests, family history, and socioeconomic information were obtained to determine the risk factors. Results The prevalence of diabetes mellitus (DM), impaired glucose tolerance (IGT), and impaired fasting glucose (IFG) were estimated at 10.11%, 8.74%, and 4.55%, respectively. Increased diastolic blood pressure, serum triglyceride, and cholesterol level were observed to be significantly (p < 0.05) associated with diabetes. Also, the presence of diabetes, high blood pressure, and obesity among relatives significantly increased the probability of diabetes. Conclusions To the best of our knowledge, this is the first study on diabetes prevalence among the Bihari community in Bangladesh. The prevalence of type 2 diabetes mellitus was found to be higher among the Bihari community compared to the general population in Bangladesh. Health planners and policymakers should realize the alarming situation and identified risk factors and consider the minor ethnic groups during decision-making regarding prevention and control of diabetes and other noncommunicable diseases.

There are many causes of impaired glucose tolerance in pregnant women. It is unclear whether genetic etiologies are a source of impaired glucose tolerance in pregnant women. To prospectively determine the prevalence of maturity onset diabetes of the young (MODY) due to glucokinase (GCK) mutations in an American population of women with recent onset diabetes mellitus and gestational diabetes. We hypothesized that based on America's higher prevalence of gestational diabetes mellitus (GDM) and Type 2 diabetes, there may be an increased prevalence of GK mutations in our population than in previously reported studies from European studies. Over a three-year period, 72 pregnant women with recently diagnosed diabetes mellitus were prospectively assessed for presence of the most common pathogenic GCK mutations. This study was performed in a gestational diabetes clinic in Urban America and a high-risk pregnancy clinic that served the military and their families on an American military base in Germany. Seventy-two women; 65 with diagnosis of diabetes mellitus in this pregnancy (GDM/overt diabetes) and 7 with diagnosis in the last nine years prior to pregnancy were recruited during pregnancy and blood samples were obtained. None. Each study participant's blood sample was analyzed with restriction fragment length polymorphism to assess for mutations in the GCK gene. There were 38 female and 34 male neonates born at 38 weeks gestation ± 1.2 weeks. Mean birth weight was 3351 g ± 450 g. There were no patients with GCK mutations found in our population 0/72. This prevalence is not greater than that seen in previous a similar study in European women with gestational diabetes, but in fact significantly less (p = 0.03). American women with recently diagnosed diabetes mellitus likely have no higher prevalence of MODY than in previously studied European women with diabetes mellitus and may have a lower prevalence.

Diabetes mellitus (DM) and related complications may increase clinical fracture risk in older adults. Our objectives were to determine if type 2 diabetes mellitus or impaired fasting glucose was associated with higher fracture rates in older adults and to evaluate how diabetic individuals with fractures differed from those without fractures. The Health, Aging, and Body Composition Study participants were well-functioning, community-dwelling men and women aged 70 to 79 years (N = 2979; 42% black), of whom 19% had DM and 6% had impaired fasting glucose at baseline. Incident nontraumatic clinical fractures were verified by radiology reports for a mean +/- SD of 4.5 +/- 1.1 years. Cox proportional hazards regression models determined how DM and impaired fasting glucose affected subsequent risk of fracture. Diabetes mellitus was associated with elevated fracture risk (relative risk, 1.64; 95% confidence interval, 1.07-2.51) after adjustment for a hip bone mineral density (BMD) and fracture risk factors. Impaired fasting glucose was not significantly associated with fractures (relative risk, 1.34; 95% confidence interval, 0.67-2.67). Diabetic participants with fractures had lower hip BMD (0.818 g/cm(2) vs 0.967 g/cm(2); P<.001) and lean mass (44.3 kg vs 51.7 kg) and were more likely to have reduced peripheral sensation (35% vs 14%), transient ischemic attack/stroke (20% vs 8%), a lower physical performance battery score (5.0 vs 7.0), and falls (37% vs 21%) compared with diabetic participants without fractures (P<.05). These results indicate that older white and black adults with DM are at higher fracture risk compared with nondiabetic adults with a similar BMD since a higher risk of nontraumatic fractures was found after adjustment for hip BMD. Fracture prevention needs to target specific risk factors found in older adults with DM.

Diabetes mellitus is a complicated metabolic disease with symptoms of hyperglycemia, insulin resistance, chronic damage and dysfunction of tissues, and metabolic syndrome for insufficient insulin production. Evidence has indicated that exercise treatments are essential in the progression of type‑ІІ diabetes mellitus, and affect insulin resistance and activity of islet β‑cells. In the present study, the efficacy and signaling mechanism of aerobic exercise on blood lipids and insulin resistance were investigated in the progression of type‑ІІ diabetes mellitus. Body weight, glucose metabolism and insulin serum levels were investigated in mouse models of type‑ІІ diabetes mellitus following experienced aerobic exercise. Expression levels of inflammatory factors, interleukin (IL)‑6, high‑sensitivity C‑reactive protein, tumor necrosis factor‑α and leucocyte differentiation antigens, soluble CD40 ligand in the serum were analyzed in the experimental mice. In addition, expression levels of toll‑like receptor 4 (TLR‑4) were analyzed in the liver cells of experimental mice. Changes of oxidative stress indicators, including reactive oxygen species, superoxide dismutase, glutathione and catalase were examined in the liver cells of experimental mice treated by aerobic exercise. Expression levels and activity of extracellular signal‑regulated kinases (ERK) and AMP‑activated protein kinase (AMPK) signaling pathways were investigated in the liver cells of mouse models of type‑ІІ diabetes mellitus after undergoing aerobic exercise. Aerobic exercise decreased the expression levels of inflammatory factors in the serum of mouse models of type‑ІІ diabetes mellitus. The results indicated that aerobic exercise downregulated oxidative stress indicators in liver cells from mouse models of type‑ІІ diabetes mellitus. In addition, the ERK and AMPK signaling pathways were inactivated by aerobic exercise in liver cells in mouse models of type‑ІІ diabetes mellitus. The activity of ERK and AMPK, and the function of islet β‑cells were observed to be improved in experimental mice treated with aerobic exercise. Furthermore, blood lipid metabolism and insulin resistance were improved by treatment with aerobic exercise. Body weight and glucose concentration of serology was markedly improved in mouse models of type‑ІІ diabetes mellitus. Furthermore, TLR‑4 inhibition markedly promoted ERK and AMPK expression levels and activity. Thus, these results indicate that aerobic exercise may improve blood lipid metabolism, insulin resistance and glucose plasma concentration in mouse models of type‑ІІ diabetes mellitus. Thus indicating aerobic exercise is beneficial for improvement of blood lipid and insulin resistance via the TLR‑4‑mediated ERK/AMPK signaling pathway in the progression of type‑ІІ diabetes mellitus.

Parenterally administered steroids have been shown to affect the metabolism of glucose and to cause abnormal blood glucose levels in diabetic patients. These abnormal blood glucose levels in diabetic patients raise concerns that intra-articular steroid injections also may affect blood glucose levels. We performed a systematic review of studies examining the effect of intra-articular steroid injections on blood glucose levels in patients with diabetes mellitus. A literature search of the PubMed, EMBASE, AMED, and CINAHL databases using all relevant keywords and phrases revealed 532 manuscripts. After the application of inclusion criteria, seven studies with a total of seventy-two patients were analyzed. All studies showed a rise in blood glucose levels following intra-articular steroid injection. Four of the seven studies showed a substantial increase in blood glucose. Peak values reached as high as 500 mg/dL. The peak increase in blood glucose did not occur immediately following intra-articular steroid injection, and in some cases it took several days to occur. In many patients, post-injection hyperglycemia occurred within twenty-four to seventy-two hours. Intra-articular steroid injections may cause hyperglycemia in patients with diabetes mellitus, and patients should be warned of this complication. Diabetic patients should be advised to regularly monitor their blood glucose levels for up to a week after injection and should seek medical advice if safe thresholds are breached. Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Dapagliflozin (Forxiga) for type 2 diabetes?
2013-09-01
In the UK, diabetes mellitus affects around 3 million people, of whom over 90% have type 2 diabetes. Aims of treatment include minimising long-term complications (e.g. cardiovascular disease, blindness, chronic kidney disease, premature mortality) and avoiding unwanted effects of treatment (e.g. severe hypoglycaemia, weight gain). Management of diabetes includes patient support and education; addressing symptoms; lifestyle modification; targeting associated risk factors for cardiovascular disease; and surveillance for, and management of, complications including treatment-related hypoglycaemia. Dapagliflozin (Forxiga) belongs to a new class of oral glucose-lowering drugs that inhibit renal glucose reabsorption and promote glycosuria. It is licensed in the UK in adults with type 2 diabetes as monotherapy when diet and exercise alone do not provide adequate glycaemic control and who are unable to tolerate metformin; or, as add-on therapy, with other glucose-lowering agents including insulin, when these, with diet and exercise, do not provide adequate glycaemic control. The company's advertising materials claim that dapagliflozin provides a "novel method of controlling excess glucose" with "secondary benefit of weight loss". Here, we review the evidence for the use of dapagliflozin in the management of type 2 diabetes mellitus.

Diabetes mellitus is a disease that affects millions of people worldwide and its prevalence is estimated to rise in the future. Billions of dollars are spent each year around the world in health expenditure related to diabetes. There are several anti-diabetic drugs in the market for the treatment of non-insulin dependent diabetes mellitus. In this article, we will be talking about a relatively new class of anti-diabetic drugs called sodium glucose co-transporter 2 (SGLT2) inhibitors. This class of drugs has a unique mechanism of action focusing on inhibition of glucose reabsorption that separates it from other classes. This article covers the mechanism of glucose reabsorption in the kidneys, the mechanism of action of SGLT2 inhibitors, several SGLT2 inhibitors currently available in the market as well as those in various phases of development, their individual pharmacokinetics as well as the discussion about the future role of SGLT2 inhibitors, not only for the treatment of diabetes, but also for various other diseases like obesity, hepatic steatosis, and cardiovascular disorders.

The objective of this study was to examine the associations among race, education, income, and health-related quality of life (HRQoL) in self-care of type 2 diabetes mellitus among adults in North Carolina. A secondary analysis was conducted using data from the 2009 Behavioral Risk Factor Surveillance Survey (BRFSS), a large population-based survey (N = 432,607) conducted in the United States. The data were analyzed to account for the weighted complex multistage sampling design of the Behavioral Risk Factor Surveillance Survey. Parametric testing using univariate/bivariate/multivariate analysis was performed. The majority of participants reported taking a class/course on diabetes mellitus management and having checked their blood glucose levels at least once per day. The majority (61.26%) of the participants did not have good self-management skills, based on the education and blood glucose-monitoring criteria established for this study. Participants with poor HRQoL had significantly increased odds of good diabetes mellitus self-care practices. Individuals with poor HRQoL had significantly increased odds of good diabetes mellitus self-care practices. Although findings on race, education, and income were not statistically significant, they were consistent with previous research. In the future, individuals who are nonwhite, have less than a high school level of education, and have no health insurance should be targeted to improve diabetes mellitus self-care practices through educational and informational materials. Further investigation using more comprehensive measures of diabetes mellitus self-care is warranted.

To determine whether stabilizing serum glucose, via introduction of an insulin pump, improves classroom attention among children with type-1 diabetes mellitus. Four boys having type-1 diabetes mellitus with unstable serum glucose were observed in their classroom for 10 baseline days. An insulin pump was placed and serum glucose stabilized, and they were then observed again for 10 days. A modified multiple baseline design was used to determine if improved on-task and off-task behavior was associated with better glycemic control. Rating scales and a laboratory measure of attention, measures of secondary interest, were also administered before and after pump introduction, and potential improvement in individuals' scores was evaluated. All boys had apparent improvement in on-task and off-task behavior as observed in their classrooms. Improvements were substantial, averaging 20% in on-task behavior and 34% in off-task behavior. However, no changes were detected on rating scales or laboratory measures. This study offers preliminary evidence that stabilizing serum glucose improves classroom attention, although the effect was detected only by observation of classroom behavior using highly structured techniques. Consequently, use of direct observation techniques may be important in studying the effects of chronic illness on classroom functioning.

Diabetes mellitus is a chronic heterogenous disease in which there is dysregulation of carbohydrates, protein and lipid metabolism; leading to elevated blood glucose levels. The present study was conducted to evaluate the correlation between blood glucose and salivary glucose levels in known diabetic patients and control group and also to evaluate salivary glucose level as a diagnostic tool in diabetic patients. A total number of 250 patients were studied, out of which 212 formed the study group and 38 formed the control group. Among 250 patients, correlation was evaluated between blood glucose and salivary glucose values which on analysis revealed Pearson correlation of 0.073. The p-value was 0.247, which was statistically non significant. Salivary glucose values cannot be considered as a diagnostic tool for diabetic individuals.

Diabetes Mellitus: Screening and Diagnosis.
Pippitt, Karly; Li, Marlana; Gurgle, Holly E
2016-01-15
Diabetes mellitus is one of the most common diagnoses made by family physicians. Uncontrolled diabetes can lead to blindness, limb amputation, kidney failure, and vascular and heart disease. Screening patients before signs and symptoms develop leads to earlier diagnosis and treatment, but may not reduce rates of end-organ damage. Randomized trials show that screening for type 2 diabetes does not reduce mortality after 10 years, although some data suggest mortality benefits after 23 to 30 years. Lifestyle and pharmacologic interventions decrease progression to diabetes in patients with impaired fasting glucose or impaired glucose tolerance. Screening for type 1 diabetes is not recommended. The U.S. Preventive Services Task Force recommends screening for abnormal blood glucose and type 2 diabetes in adults 40 to 70 years of age who are overweight or obese, and repeating testing every three years if results are normal. Individuals at higher risk should be considered for earlier and more frequent screening. The American Diabetes Association recommends screening for type 2 diabetes annually in patients 45 years and older, or in patients younger than 45 years with major risk factors. The diagnosis can be made with a fasting plasma glucose level of 126 mg per dL or greater; an A1C level of 6.5% or greater; a random plasma glucose level of 200 mg per dL or greater; or a 75-g two-hour oral glucose tolerance test with a plasma glucose level of 200 mg per dL or greater. Results should be confirmed with repeat testing on a subsequent day; however, a single random plasma glucose level of 200 mg per dL or greater with typical signs and symptoms of hyperglycemia likely indicates diabetes. Additional testing to determine the etiology of diabetes is not routinely recommended.

Background: Saliva is a unique fluid, which is important for normal functioning of the oral cavity. Diabetes mellitus (DM) is a disease of absolute or relative insulin deficiency characterized by insufficient secretion of insulin by pancreatic beta-cells. The diagnosis of diabetes through blood is difficult in children, older adults, debilitated and chronically ill patients, so diagnosis by analysis of saliva can be potentially valuable as collection of saliva is noninvasive, easier and technically insensitive, unlike blood. The aim of the study was to correlate blood glucose level (BGL) and salivary glucose level (SGL) in DM patients. Methodology: A cross-sectional study was conducted in 120 patients, who were categorized as 40 controlled diabetics, 40 uncontrolled diabetics and 40 healthy, age- and sex-matched individuals constituted the controls. The blood and unstimulated saliva samples were collected from the patients at the different intervals for fasting, random and postprandial levels. These samples were then subjected for analysis of glucose in blood and saliva using glucose oxidase/peroxidase reagent in HITACHI 902(R) Automatic analyzer, and the results were recorded. Results: The mean SGLs were higher in uncontrolled and controlled diabetic groups than in nondiabetic group. A highly statistically significant correlation was found between fasting saliva glucose and fasting blood glucose in all the groups. Conclusion: With increase in BGL, increase in SGL was observed in patients with diabetes suggesting that SGL can be used for monitoring glycemic level in DM. PMID:29391704

[Suitability of screening for diabetes mellitus in women with a history of gestational diabetes].
Álvarez-Silvares, E; Domínguez-Vigo, P; Domínguez-Sánchez, J; González-González, A
To assess long-term suitability of screening for type 2 diabetes mellitus in women with a previous diagnosis of gestational diabetes in Primary Care. The secondary objectives were to determine if there were clinical factors that modified the usefulness of the screening. An observational cohort type study was performed, which included all patients with the diagnosis of gestational diabetes during the years 2000 to 2009 (n=470) in the University Hospital Complex of Ourense. The electronic medical records were reviewed to assess the existence of gestational diabetes and the year of the last fasting blood glucose. The mean follow-up time was 12.9 years. The screening for evidence of a fasting blood glucose in the last 3 years was considered adequate. The following variables were analysed: adequacy of screening for type 2 diabetes mellitus, age, body mass index, gestational diabetes in more than one gestation, and rural/urban environment. A descriptive analysis of the data was performed, using Chi2 and Student's t-test to determine differences between subgroups. Statistical significance was considered as P<.05 RESULTS: The long-term monitoring of these patients was very irregular. Only 67.08% of the study group underwent diabetes mellitus type 2 screening. The level of follow-up was not associated with age, BMI, the place of residence, or the year of diagnosis. In patients with more than one episode of gestational diabetes, subsequent blood glucose control was achieved in 94.1%. The adequacy of the screening in our area is very irregular and highly improvable. Copyright © 2017 SECA. Publicado por Elsevier España, S.L.U. All rights reserved.

Redox imbalance stress in diabetes mellitus: Role of the polyol pathway.
Yan, Liang-Jun
2018-03-01
In diabetes mellitus, the polyol pathway is highly active and consumes approximately 30% glucose in the body. This pathway contains 2 reactions catalyzed by aldose reductase (AR) and sorbitol dehydrogenase, respectively. AR reduces glucose to sorbitol at the expense of NADPH, while sorbitol dehydrogenase converts sorbitol to fructose at the expense of NAD + , leading to NADH production. Consumption of NADPH, accumulation of sorbitol, and generation of fructose and NADH have all been implicated in the pathogenesis of diabetes and its complications. In this review, the roles of this pathway in NADH/NAD + redox imbalance stress and oxidative stress in diabetes are highlighted. A potential intervention using nicotinamide riboside to restore redox balance as an approach to fighting diabetes is also discussed.

Dogs do not appear to progress from obesity-induced insulin resistance to type 2 diabetes mellitus. Both postprandial hyperglycemia and postprandial hypertriglyceridemia have been proposed to cause or maintain beta cell failure and progression to type 2 diabetes mellitus in other species. Postprandial glucose, triglyceride, and insulin concentrations have not been compared in lean and obese dogs. We measured serum glucose, triglyceride, and insulin concentrations in nine naturally occurring obese and nine age- and gender-matched lean dogs. After a 24-h fast, dogs were fed half their calculated daily energy requirement of a standardized diet that provided 37% and 40% of metabolizable energy as carbohydrate and fat, respectively. Fasting and postprandial glucose and triglyceride concentrations were greater in the obese dogs (P < 0.001), although the mean insulin concentration for this group was five times greater than that of the lean group (P < 0.001). Most of the 0.6 mM (11 mg/dL) difference in mean postprandial glucose concentrations between lean and obese dogs was attributable to a subset of persistently hyperglycemic obese dogs with mean postprandial glucose concentrations 1.0 mM (18 mg/dL) greater than that in lean dogs. Persistently hyperglycemic obese dogs had lower triglyceride (P = 0.02 to 0.04) and insulin (P < 0.02) concentrations than other obese dogs. None of the dogs developed clinical signs of diabetes mellitus during follow-up for a median of 2.6 yr. We conclude that pancreatic beta cells in dogs are either not sensitive to toxicity because of mild hyperglycemia or lack another component of the pathophysiology of beta cell failure in type 2 diabetes mellitus.

To determine whether changes in insulin-like growth factor (IGF) protein levels are greater in participants with type 2 diabetes mellitus or worsening glycemia than in normoglycemic individuals over a 9-year follow-up period. Retrospective analysis of a cohort study. Participants were recruited from North Carolina, California, Maryland, and Pennsylvania. Cardiovascular Health Study All Stars participants, a cohort study of community-dwelling adults aged 65 and older (N=897). Plasma IGF-I, IGF binding protein (IGFBP)-1, and IGFBP-3 levels were assessed and American Diabetes Association cut-points for impaired glucose tolerance (IGT), impaired fasting glucose (IFG), and diabetes mellitus were used to classify participants at baseline (1996-97) and follow-up (2005-06). At baseline, mean age was 76.3±3.6, and 18.5% had diabetes mellitus. Participants with IFG alone and IGT plus IFG had higher IGF-I levels and lower IGFBP-1 levels than those with normoglycemia or diabetes mellitus. The greatest percentage change in IGF levels occurred in those who had diabetes mellitus at baseline (9-year changes: -9.3% for IGF-I, 59.7% for IGFBP-1, -13.4% for IGFBP-3), the smallest in individuals who remained normoglycemic at follow-up (9-year changes: -3.7% for IGF-I, 25.6% for IGFBP-1, -6.4% for IGFBP-3), and intermediate in those who were normoglycemic but developed IFG at follow-up. Degrees of glycemic impairment are associated with varying degrees of change in IGF protein levels. The changes observed in the diabetes mellitus group have been previously shown to be associated with heart failure, cancer, and noncancer mortality. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

Activation of inflammatory pathways is involved in the pathogenesis of type 2 diabetes mellitus. On the basis of its role in vascular inflammation and in metabolic disorders, we hypothesised that the TNF superfamily (TNFSF) member 14 (LIGHT/TNFSF14) could be involved in the pathogenesis of type 2 diabetes mellitus. Plasma levels of LIGHT were measured in two cohorts of type 2 diabetes mellitus patients (191 Italian and 40 Norwegian). Human pancreatic islet cells and arterial endothelial cells were used to explore regulation and relevant effects of LIGHT in vitro. Our major findings were: (1) in both diabetic cohorts, plasma levels of LIGHT were significantly raised compared with sex- and age-matched healthy controls (n = 32); (2) enhanced release from activated platelets seems to be an important contributor to the raised LIGHT levels in type 2 diabetes mellitus; (3) in human pancreatic islet cells, inflammatory cytokines increased the release of LIGHT and upregulated mRNA and protein levels of the LIGHT receptors lymphotoxin β receptor (LTβR) and TNF receptor superfamily member 14 (HVEM/TNFRSF14); (4) in these cells, LIGHT attenuated the insulin release in response to high glucose at least partly via pro-apoptotic effects; and (5) in human arterial endothelial cells, glucose boosted inflammatory response to LIGHT, accompanied by an upregulation of mRNA levels of HVEM (also known as TNFRSF14) and LTβR (also known as LTBR). Our findings show that patients with type 2 diabetes mellitus are characterised by increased plasma LIGHT levels. Our in vitro findings suggest that LIGHT may contribute to the progression of type 2 diabetes mellitus by attenuating insulin secretion in pancreatic islet cells and by contributing to vascular inflammation.

Continuous glucose monitoring (CGM), which enables real-time glucose display and trend information as well as real-time alarms, can improve glycemic control and quality of life in patients with diabetes mellitus. Previous reports have described strategies to extend the useable lifetime of a single sensor from 1-2 weeks to 28 days. The present multisite study describes the characterization of a sensing platform achieving 90 days of continuous use for a single, fully implanted sensor. The Senseonics CGM system is composed of a long-term implantable glucose sensor and a wearable smart transmitter. Study subjects underwent subcutaneous implantation of sensors in the upper arm. Eight-hour clinic sessions were performed every 14 days, during which sensor glucose values were compared against venous blood lab reference measurements collected every 15 minutes using mean absolute relative differences (MARDs). All subjects (mean ± standard deviation age: 43.5 ± 11.0 years; with 10 sensors inserted in men and 14 in women) had type 1 diabetes mellitus. Most (22 of 24) sensors reported glucose values for the entire 90 days. The MARD value was 11.4 ± 2.7% (range, 8.1-19.5%) for reference glucose values between 40-400 mg/dl. There was no significant difference in MARD throughout the 90-day study (P = .31). No serious adverse events were noted. The Senseonics CGM, composed of an implantable sensor, external smart transmitter, and smartphone app, is the first system that uses a single sensor for continuous display of accurate glucose values for 3 months. © 2015 Diabetes Technology Society.

Combined pegylated interferon (PEG-IFN)+ribavirin (RBV) therapy has been used as a primary treatment for chronic hepatitis C. However, IFN-induced autoimmune disease, including type 1 diabetes mellitus, has been highlighted as one of the problems with this therapy. Here we report the case of a patient who developed type 1 diabetes mellitus during combined PEG-IFN+RBV therapy for hepatitis C but who showed no exacerbation of diabetes despite continued use of IFN. A 63-year-old man with chronic hepatitis C and a nonresponder to previous IFNα treatments, was admitted to our hospital because of excessive thirst, polydipsia, and polyuria 24 weeks after the start of PEG-IFNα+RBV therapy. High levels of blood glucose and glycosylated hemoglobin and low levels of C-peptide and immunoreactive insulin were observed. The serum antiglutamic acid decarboxylase antibody titer was 27,700 U/mL. We diagnosed IFN-induced type 1 diabetes mellitus; however PEG-IFNα+RBV therapy was continued for 48 weeks. Serum HCV remains negative five years after this treatment. Intensive insulin therapy was started immediately after the diagnosis of type 1 diabetes. Although the patient initially required 22 U/day of insulin, the dosage could be gradually reduced after completion of PEG-IFNα+RBV therapy and blood glucose remained well controlled. Prediction of onset of type 1 diabetes mellitus on the basis of baseline measurement of pancreas-associated autoantibodies is difficult. Therefore, it would be advisable to consider the possibility of onset of type 1 diabetes mellitus in all patients receiving IFN+RBV therapy.

Type 2 diabetes mellitus is a heterogeneous disease of polygenic origin and involves both defective insulin secretion and peripheral insulin resistance. Studies have shown that post-meal hyperglycemic spikes are associated with increased cardiovascular mortality in type 2 diabetes. Over the past decade, a major interest in control of postprandial glucose excursion has emerged and a plethora of new medications that specifically target postprandial hyperglycemia were discovered. Despite the availability of new agents for treatment of type 2 diabetes mellitus, oral sulfonylureas remain a cornerstone of therapy, because they are relatively inexpensive and are well tolerated. However, hypoglycemia is a major safety concern with sulfonylureas and it is one major risk factor requiring hospitalization. Glipizide is a potent, rapid-acting with short duration of action and well tolerated second-generation sulfonylurea effective in reducing postprandial glucose levels. However, risk of postprandial hypoglycemia and post-meal glucose excursions, if dose missed before meal; are always associated with the use of glipizide for treatment of type 2 diabetes mellitus. Since, the site of absorption of glipizide is from stomach thus dosage forms that are retained in stomach by mucoadhesion; would increase absorption, improve drug efficiency and decrease dose requirements. Microsphere carrier systems made by using polymer galactomannan having strong mucoadhesive properties and easily biodegradable could be an attractive strategy to formulate. The purpose of this research work is to formulate galactomannan coated mucoadhesive microspheres of glipizide and systematically evaluate its in vitro characteristics and in vivo performance for sustained glucose lowering effect and improvement in diabetic condition as compared to immediate release of glipizide.

Hyperglycaemia that is induced short-term slows gastric emptying in healthy subjects and patients with diabetes mellitus. Little information is available on the impact of longer-lasting, naturally occurring blood glucose increases and their reduction to euglycaemic values. We studied the relation between gastric emptying and pre-prandial and postprandial blood glucose concentrations in patients with Type II (non-insulin-dependent) diabetes mellitus and secondary failure to respond to oral hypoglycaemic treatment (a) before readjusting hypoglycaemic therapy and (b) 1 week thereafter. We studied 9 female and 1 male patient (age 60-78 years, BMI 21.9-32.5 kg/m2, diabetes duration 3-33 years, HbA1c 8.8-13.2%). Gastric emptying of a radiolabelled semisolid 1168 kJ meal was recorded scintigraphically. Blood glucose concentration pre-prandial and postprandial was considerably lower subsequent to than before therapy readjustment in all patients (fasting, 7.9 mmol/l+/-1.5 SD vs 11.7+/-1.7 mmol/l; 60 min postprandial, 11.7+/-2.0 vs 15.4+/-2.2 mmol/l). By contrast, gastric emptying was unchanged (residual radioactivity in stomach 50 min postprandial 65.7+/-14.1% vs 66.5+/-12.9%). There was no relation between emptying and either fasting blood glucose concentration or its postprandial increase. The data do not support a major impact of actual, longer-lasting, naturally occurring blood glucose concentrations upon the rate of gastric emptying in patients with Type II diabetes.

According to previous studies, cinnamon may have a positive effect on the glycaemic control and the lipid profile in patients with diabetes mellitus type 2. The aim of this trial was to determine whether an aqueous cinnamon purified extract improves glycated haemoglobin A1c (HbA1c), fasting plasma glucose, total cholesterol, low-density lipoprotein (LDL), high-density lipoprotein (HDL) and triacylglycerol concentrations in patients with type 2 diabetes. A total of 79 patients with diagnosed diabetes mellitus type 2 not on insulin therapy but treated with oral antidiabetics or diet were randomly assigned to take either a cinnamon extract or a placebo capsule three times a day for 4 months in a double-blind study. The amount of aqueous cinnamon extract corresponded to 3 g of cinnamon powder per day. The mean absolute and percentage differences between the pre- and post-intervention fasting plasma glucose level of the cinnamon and placebo groups were significantly different. There was a significantly higher reduction in the cinnamon group (10.3%) than in the placebo group (3.4%). No significant intragroup or intergroup differences were observed regarding HbA1c, lipid profiles or differences between the pre- and postintervention levels of these variables. The decrease in plasma glucose correlated significantly with the baseline concentrations, indicating that subjects with a higher initial plasma glucose level may benefit more from cinnamon intake. No adverse effects were observed. The cinnamon extract seems to have a moderate effect in reducing fasting plasma glucose concentrations in diabetic patients with poor glycaemic control.

Patients with diabetes mellitus have an increased risk of suffering atherothrombotic syndromes and are prone to clustering cardiovascular risk factors. However, despite their dysregulated glucose metabolism, intensive glycemic control has proven insufficient to reduce thrombotic complications. Therefore, we aimed to elucidate the determinants of thrombosis in a model of type 2 diabetes mellitus with cardiovascular risk factors clustering. Intravital microscopy was used to analyze thrombosis in vivo in Zucker diabetic fatty rats (ZD) and lean normoglycemic controls. Bone marrow (BM) transplants were performed to test the contribution of each compartment (blood or vessel wall) to thrombogenicity. ZD showed significantly increased thrombosis compared with lean normoglycemic controls. BM transplants demonstrated the key contribution of the hematopoietic compartment to increased thrombogenicity. Indeed, lean normoglycemic controls transplanted with ZD-BM showed increased thrombosis with normal glucose levels, whereas ZD transplanted with lean normoglycemic controls-BM showed reduced thrombosis despite presenting hyperglycemia. Significant alterations in megakaryopoiesis and platelet-endoplasmic reticulum stress proteins, protein disulfide isomerase and 78-kDa glucose-regulated protein, were detected in ZD, and increased tissue factor procoagulant activity was detected in plasma and whole blood of ZD. Our results indicate that diabetes mellitus with cardiovascular risk factor clustering favors BM production of hyperreactive platelets with altered protein disulfide isomerase and 78-kDa glucose-regulated protein expression that can contribute to increase thrombotic risk independently of blood glucose levels.

Objective: To analyze the rates on prevalence, awareness, status on treatment and control of type 2 diabetes mellitus among Chinese premenopausal women aged 18-49, in 2013. Methods: Data on China Chronic and Non-Communicable Disease Surveillance in year 2013 was used for analysis. Source of data covered 302 surveillance points which were selected by Multi-stage cluster random sampling method that including 176 534 adults over 18 years of age, with 46 674 premenopausal women aged 18-49. Plasma glucose and hemoglobin A1c levels were determined after a 10-hour overnight fast for all the participants, before a 2-hour oral glucose tolerance test was conducted among participants without a self-reported history of diagnosed diabetes. Diabetes was defined according to the 1999 WHO diagnostic criteria-fasting blood glucose level as ≥7.0 mmol/L and/or 2 hours oral glucose tolerance test (OGTT-2 h) level as ≥11.1 mmol/L. After being weighed, according to complex sampling scheme and post-stratification, the sample was used to estimate the rates of prevalence, awareness, treatment and control of type 2 diabetes mellitus by age, education, urban and rural areas, and geographic locations. Results: The overall prevalence of type 2 diabetes mellitus was 5.6% among the Chinese premenopausal women aged 18-49. No statistical difference on the prevalence rates (5.7% and 5.4%, respectively) was seen, between participants from the rural or the urban areas. Prevalence rates in the eastern, central or western geographic areas were 5.8%, 6.2% and 4.4% respectively. The rates of awareness, treatment and control of diabetes appeared as 29.3%, 27.9% and 29.4% in childbearing women aged 18-49. The rate of treatment was 95.4% among those who knew their diabetic situation in childbearing women aged 18-49 years. The control rate of diabetes was 38.9% among those who had taken measures to control glucose, in 18-49-year-old childbearing women. The rate of awareness on diabetes in childbearing women aged 18-49 years in urban areas was higher than that in the rural areas. There were significantly statistical differences on the treatment rates among groups of different education levels but not in the trend test. Conclusion: The prevalence of type 2 diabetes mellitus in childbearing women aged 18-49 appeared high, but with low rates on awareness, treatment and control. However, statistical difference was seen on awareness, between urban and rural areas.

Antipsychotic Therapy-Induced New Onset Diabetic Ketoacidosis.
Agrawal, Yashwant; Lingala, Kiran; Tokala, Hemasri; Kalavakunta, Jagadeesh K
Atypical antipsychotics are very widely used for various psychiatric ailments because of their less extrapyramidal side effects. Various reports of disturbances in glucose metabolism in the form of new onset diabetes mellitus, exacerbation of preexisting diabetes mellitus, diabetic ketoacidosis, hyperosmolar nonketotic coma, acute pancreatitis, and increased adiposity have been reported. We present a case of new onset diabetic ketoacidosis in a patient without a history of glucose intolerance who was being treated with olanzapine for bipolar disorder. He presented in hyperglycemic, hyperosmolar, hyperketotic state with hyperkalemia, and peaked T waves on electrocardiogram. He was treated with vigorous intravenous hydration, insulin, and kaexylate which stabilized his metabolic profile. He was discontinued off of his olanzapine and started on resperidol for his bipolar disorder. Over the course of 6 months, the patient was discontinued off of his insulin and has been doing well on his follow-up appointments. This case highlights the necessity of close blood glucose monitoring of patient on atypical antipsychotic medications irrespective of their diabetic status.

To explore the protective effect of the drug Semecarpus anacardium (S. anacardium)on altered glucose metabolism in diabetic rats. Type 2 diabetes mellitus was induced by feeding rats with high fat diet followed by single intraperitoneal injection of streptozotocin (STZ) (35 mg/kg b.w.). Seven days after STZ induction, diabetic rats received nut milk extract of S. anacardium Linn. nut milk extract orally at a dosage of 200 mg/kg daily for 4 weeks. The effect of nut milk extract of S. anacardium on blood glucose, plasma insulin, glucose metabolising enzymes and GSK were studied. Treatment with SA extract showed a significant reduction in blood glucose levels and increase in plasma insulin levels and also increase in HOMA - β and decrease in HOMA -IR. The drug significantly increased the activity of glycolytic enzymes and glucose-6-phosphate dehydrogenase activity and increased the glycogen content in liver of diabetic rats while reducing the activities of gluconeogenic enzymes. The drug also effectively ameliorated the alterations in GSK-3 mRNA expression. Overall, the present study demonstrates the possible mechanism of glucose regulation of S. anacardium suggestive of its therapeutic potential for the management of diabetes mellitus.

The antihyperglycemic effect of syringaldehyde (1), purified from the stems of Hibiscus taiwanensis, was investigated in streptozotocin-induced diabetic rats (STZ-diabetic rats) showing type-1 like diabetes mellitus. Bolus intravenous injection of 1 showed antihyperglycemic activity in a dose-dependent manner in STZ-diabetic rats. An effective dose of 7.2 mg/kg of 1 attenuated significantly the increase of plasma glucose induced by an intravenous glucose challenge test in normal rats. A glucose uptake test showed that 1 exhibits an increase of glucose uptake activity in a concentration-related manner. Moreover, an effect by 1 was shown for insulin sensitivity in STZ-diabetic rats. The compound was found to increase insulin sensitivity in STZ-diabetic rats. These results suggest that syringaldehyde (1) can increase glucose utilization and insulin sensitivity to lower plasma glucose in diabetic rats.

Rosa canina fruits have been used traditionally for the treatment of diabetes mellitus and its complications. The aim of current study was to evaluate the in vitro mechanism of action of R canina in managing diabetes mellitus. Cell proliferation and cytotoxicity assay were performed on pancreatic β-cells, βTC6. The protective activity of the extract on streptozotocin-induced death in βTC6 cells was studied. The effect of R canina on the metabolism of glucose in HepG2, a hepatocellular carcinoma cell line, was evaluated. The effect of the extract on glucose diffusion across the dialysis membrane, which is a comfortable model for assessing cellular glucose absorption, was evaluated. The results obtained from current study confirmed that R canina extract can act as a growth factor for pancreatic β-cell line providing a novel mechanism for the observed antidiabetic effect of this natural agent. Further preclinical studies are necessary to evaluate the perfect mechanism of action of R canina in diabetes mellitus. PMID:27352916

Type 2 diabetes mellitus is a progressive disease with multiple underlying pathophysiologic defects. Monotherapy alone cannot maintain glycemic control and leads to treatment failure. Ideally, a combination of glucose-lowering agents should have complementary mechanisms of action that address multiple pathophysiologic pathways, can be used at all stages of the disease, and be generally well tolerated with no increased risk of hypoglycemia, cardiovascular events, or weight gain. The combination should also provide conveniences for patients, such as oral dosing, single-pill formulations, and once-daily administration, potentially translating to improved adherence. Two classes of glucose-lowering agents that meet these criteria are the sodium glucose cotransporter-2 (SGLT2) inhibitors and dipeptidyl peptidase-4 (DPP-4) inhibitors. This article reviews the rationale for combination therapy with these agents, and evidence from clinical trials with empagliflozin and linagliptin or dapagliflozin and saxagliptin in the management of type 2 diabetes mellitus. Both combinations have been approved as single-pill formulations.

Diabetes mellitus is a chronic physiological glucose metabolic disorder. Its high prevalence globally has a significant impact on the quality of life. The management of diabetes includes non-pharmacological and glucose lowering agents. Although these methods are effective, they have drawbacks. This has led to a search for alternative therapy in macro and micro-minerals from dietary foods and plants. There is therefore a need to review, identify and classify their modes of action in diabetes mellitus therapy. This review was carried out using comprehensive literature reports on the use of mineral elements in the management of diabetes. Empirical online searches were conducted for different elements that have been studied for their anti-diabetic potentials both in vivo and in vitro. The University of Fort Hare's online database was also used. The results indicate that magnesium, molybdenum, zinc, vanadium and manganese facilitate glucose catabolism. Chromium, vanadium, zinc, molybdenum and magnesium can enhance insulin activity while molybdenum, manganese and zinc stimulate lipogenesis. Zinc and iron can modulate glucose, metabolizing enzymes in the gastrointestinal tract and limit oxidative stress, respectively. These agents have similar mechanisms to conventional drugs in ameliorating diabetic status and other associated complications. The mechanisms of these elements are well known, however, the synergetic effects of their combinations are still obscure. Literature on their safe dose(s) is still scanty. Evaluation of other useful macro and micro-minerals should also be undertaken. It is envisaged that the use of mineral supplements will promote good health in diabetics.

Thyroid disease and diabetes mellitus, the most common disorders in endocrine practice, are not infrequently associated in the same subject. An altered thyroid function may affect glucose tolerance and worsen metabolic control in patients with diabetes. Thyrotoxicosis increases the risk of hyperglycemic emergencies, while a clinically relevant hypothyroidism may have a detrimental effect on glycemic control in diabetic patients. The association of alterations in thyroid function with diabetes mellitus may adversely affect the risk of cardiovascular and microvascular complications resulting from diabetes. Moreover, the treatments used for both diabetes and thyroid disease, respectively, can impact one other. Finally, multinodular goiter, but not thyroid carcinoma, was shown to be more prevalent in type 2 diabetes mellitus. Aim of the present Position Statement is to focus on the evidence concerning the association of thyroid disease and diabetes mellitus and to provide some practical suggestions for an updated clinical management.

A history of continuous glucose monitors (CGMs) in self-monitoring of diabetes mellitus.
Olczuk, David; Priefer, Ronny
Self-monitoring of glucose for individuals afflicted with diabetes mellitus has allowed patients to take control of their disease and thus directly affect the outcomes related to it. It has been almost a century since the first test to monitor one's sugar was developed; that being a urine test. The most well-known and prominent medical device for monitor blood glucose for individuals with diabetes are the finger-prick devices. This itself is an approximately 50year old technology. More recently has been the introduction of continuous glucose monitors (CGMs) which entered the market place in the last year of the 20th century. As this technology has been further refined and improved, limitations associated with it have decreased. The scope of this review is to present a brief history of CGMs, both with the development of these medical devices and the challenges/limitations that they have shown.

Efficacy of high-fiber diets in the management of type 2 diabetes mellitus.
Wolfram, Taylor; Ismail-Beigi, Faramarz
2011-01-01
To review outcomes of randomized controlled clinical trials exploring the efficacy of different types of diets containing various amounts of fiber in the management of type 2 diabetes mellitus. We searched PubMed, Medline, and Google Scholar for published data from the past decade (through December 2009) on dietary patterns and risk of type 2 diabetes mellitus. Only randomized controlled trials investigating the effect of whole grains, fiber, or vegetarian diets on type 2 diabetes were included. Search criteria included whole grain, fruit, vegetable, fiber, and meat intake regarding insulin sensitivity and glycemic responses in healthy, prediabetic, and diabetic persons. A total of 14 randomized clinical trials were included. Addition of insoluble or soluble fiber to meals, increased consumption of diets rich in whole grains and vegetables, and vegan diets improve glucose metabolism and increase insulin sensitivity. The greatest improvement in blood lipids, body weight, and hemoglobin A(1c) level occurred in participants following low-fat, plant-based diets. Increased consumption of vegetables, whole grains, and soluble and insoluble fiber is associated with improved glucose metabolism in both diabetic and nondiabetic individuals. Improvements in insulin sensitivity and glucose homeostasis were more evident in participants following a plant-based diet compared with other commonly used diets.

Kanadys, W M; Oleszczuk, J
1999-10-01
This study was undertaken to determine the incidence of gestational diabetes mellitus. This study involved analysis of data collected prospectively from a cohort of women who received prenatal care from Outpatient Department for Women, from 1994 to 1998. The population consisted of 1017 pregnant women. It is a group of patients living mainly in geographical area, including Czechów district in Lublin. Therefore, it represents quantitative relations characteristics in natural conditions of the place of residence of a larger group of municipality population. Glucose challenge test (GCT) according to indications of Experts Team of Polish Diabetologic Society in early diagnostics of gestational diabetes melitus--a 50-g loading dose of glucose and 1-h test was considered abnormal if value was 140 mg/dl (7.8 mmol/L). Patients with abnormal GCT underwent an oral glucose tolerance test (GTT) according to criteria the World Health Organization, e.g., venous plasma glucose 2 h after 75 g oral glucose load > 140 mg/dl (7.8 mmol/L). From patients screened for GDM between 24 and 28 wk gestation, 59 (5.8%) showed an abnormal GCT and from these 18 (1.8%) had an abnormal GTT. The testing sequence was repeated in 32 wk gestation among patients with normal GTT after an abnormal GCT and 1 had abnormal GTT. Incidence of gestational diabetes mellitus is shown to be 1.9%.

Diabetes mellitus is a major global health problem. Needling at CV-12 has reduced blood glucose level in diabetic rats. The aim of this study was to evaluate the effect of needling at CV-12 (Zhongwan) on blood glucose level in patients with type 2 diabetes mellitus (T2DM). Forty T2DM patients were recruited and randomized into either the acupuncture group or placebo control group. The participants in the acupuncture group were needled at CV-12 (4 cun above the center of the umbilicus), and those in the placebo control group were needled at a placebo point on the right side of the abdomen (1 cun beside the CV-12). For both groups, the needle was retained for 30 minutes. Assessments were performed prior to and after the intervention. Statistical analysis was performed using SPSS version 16. There was a significant reduction in random blood glucose level in the acupuncture group compared to baseline. No such significant change was observed in the placebo control group. The result of this study suggests that 30 minutes of needling at CV-12 might be useful in reducing blood glucose level in patients with T2DM. Copyright © 2017. Published by Elsevier B.V.

Appropriate glycemic control without hypoglycemia is important in patients with type 2 diabetes on hemodialysis. Teneligliptin, a novel dipeptidyl peptidase-4 inhibitor, can be used without dose adjustment for these patients. Using continuous glucose monitoring (CGM), we evaluated the efficacy and safety of adding teneligliptin to insulin therapy. Twenty-one type 2 diabetes mellitus patients on hemodialysis treated with insulin were enrolled. After the adjustment of insulin dose, their blood glucose level was monitored by CGM. Insulin dose was reduced after teneligliptin administration. The median total daily insulin dose significantly reduced from 18 (9-24)U to 6 (0-14)U (p<0.0001). Maximum, mean, and standard deviation of blood glucose level on the hemodialysis and non-hemodialysis days did not change after teneligliptin administration. However, minimum blood glucose level was significantly elevated on the hemodialysis day after teneligliptin administration (from 3.9±1.0mmol/L to 4.4±0.9mmol/L, p=0.040). The incidence of asymptomatic hypoglycemia on the hemodialysis day detected by CGM significantly decreased from 38.1% to 19.0% (p=0.049). Teneligliptin may contribute toward reducing the total daily insulin dose and preventing hypoglycemic events on the hemodialysis day in type 2 diabetes mellitus patients.

Diabetes Mellitus (DM) is one of the non-communicable diseases and public health problems facing the worldwide population that includes Malaysia. Hitherto, the prevalence of DM becomes worsening with an estimated of 3.4 million Malaysians are diabetes sufferers and expectedly increasing year by year. Thus, this study is of great importance by regressing the medical factors that affect the blood glucose level using structural equation modelling (SEM). The SEM with partial least squares (PLS) estimation was applied to a secondary data of 644 respondents, aged ≥ 18 years in Malaysia. The data were collected in 2011 by Ministry of Health Malaysia (MOH). The variables under study are blood glucose level, cholesterol level (CL), systolic blood pressure (SBP), diastolic blood pressure (DBP), waist circumference (WC) and body mass index (BMI). From the modelling analysis, it showed that the cholesterol level (CL), systolic blood pressure (SBP) and waist circumference (WC) showed a positive significant relationship p < 0.01 (one-tailed) in influencing the blood sugar level. Whereas, diastolic blood pressure (DBP) is positively significant at p < 0.05 (one-tailed) and body mass index (BMI) is significant at p < 0.10 (one-tailed) towards blood glucose level. In conclusions, the findings from this study revealed the most salient predictors for blood glucose level which are CL, SBP and WC for diabetes mellitus among adults.

Obesity and metabolic surgery in type 1 diabetes mellitus.
Raab, Heike; Weiner, R A; Frenken, M; Rett, K; Weiner, S
2013-03-01
Obesity surgery is an effective method for treating obesity and diabetes mellitus type 2. This type of diabetes can be completely resolved in 78.1% of diabetic patients and can be improved or resolved in 86.6% of diabetic patients. But little is known about bariatric surgery in type 1 diabetes mellitus. We report of 6 female obese patients with diabetes mellitus type 1 who had bariatric surgery. Two of them underwent Roux-en Y gastric bypass (RNYGB), one of them had sleeve gastrectomy and the remaining three had biliopancreatic diversion with duodenal-switch (BPD-DS). Our results showed a remarkable weight reduction as well as an improvement in their blood glucose control and the insulin requirement in the followup years after surgery. Pre-surgery the BMI of our 6 patients ranged between 37.3-46.0 kg/m2 and improved to 25.8-29.0 kg/m2 one year after surgery. HbA1c decreased from 6.7-9.8% pre-surgery to 5.7-8.5% after one year post-surgery. The total amount of daily insulin requirement was reduced from 62-150 IU/day pre-surgery to 15- 54 IU/day after one year. The results are impressive and show an improvement in insulin sensitivity following obesity surgery. However, an optimal blood glucose control still remains very important in the therapy of diabetes mellitus type 1 to avoid long-term-complications. Copyright © AULA MEDICA EDICIONES 2013.

An increase in gestational diabetes mellitus (GDM) prevalence has been demonstrated across many countries with adoption of the International Association of the Diabetes and Pregnancy Study Groups (IADPSG) diagnostic criteria. Here, we determine the cumulative incidence of abnormal glucose tolerance among women with previous GDM, and identify clinical risk factors predicting this. Two hundred and seventy women with previous IADPSG-defined GDM were prospectively followed up for 5years (mean 2.6) post-index pregnancy, and compared with 388 women with normal glucose tolerance (NGT) in pregnancy. Cumulative incidence of abnormal glucose tolerance (using American Diabetes Association criteria for impaired fasting glucose, impaired glucose tolerance and diabetes) was determined using the Kaplan-Meier method of survival analysis. Cox regression models were constructed to test for factors predicting abnormal glucose tolerance. Twenty-six percent of women with previous GDM had abnormal glucose tolerance vs 4% with NGT, with the log-rank test demonstrating significantly different survival curves (P<0.001). Women meeting IADPSG, but not the World Health Organization (WHO) 1999 criteria, had a lower cumulative incidence than women meeting both sets of criteria, both in the early post-partum period (4.2% vs 21.7%, P<0.001) and at longer-term follow-up (13.7% vs 32.6%, P<0.001). Predictive factors were glucose levels on the pregnancy oral glucose tolerance test, family history of diabetes, gestational week at testing, and BMI at follow-up. The proportion of women developing abnormal glucose tolerance remains high among those with IADPSG-defined GDM. This demonstrates the need for continued close follow-up, although the optimal frequency and method needs further study. © 2016 European Society of Endocrinology.

2015-07-01
To investigate the effects of insulin detemir in dogs with diabetes mellitus. Prospective, uncontrolled clinical trial. 10 client-owned dogs with naturally occurring diabetes mellitus. Dogs were treated with insulin detemir SC every 12 hours for 6 months. Follow-up evaluations were done at 1, 2, 4, 12, and 24 weeks and included evaluation of clinical signs and measurement of blood glucose concentration curves and serum fructosamine concentrations. Insulin detemir administration resulted in a significant decrease in blood glucose and serum fructosamine concentrations at 6 months, compared with pretreatment values. Median insulin dosage at the end of the study was 0.12 U/kg (0.055 U/lb; range, 0.05 to 0.34 U/kg [0.023 to 0.155 U/lb], SC, q 12 h). Hypoglycemia was identified in 22% (10/45) of the blood glucose concentration curves, and 6 episodes of clinical hypoglycemia in 4 dogs were recorded. A subjective improvement in clinical signs was observed in all dogs during the 6-month study period. On the basis of clinical signs and blood glucose concentration curves, efficacy of insulin detemir at the end of the study was considered good in 5 dogs, moderate in 3, and poor in 2. Results suggested that SC injection of insulin detemir every 12 hours may be a viable treatment for diabetes mellitus in dogs. Insulin detemir dosages were lower than reported dosages of other insulin types needed to maintain glycemic control, suggesting that insulin detemir should be used with caution, especially in small dogs.

Individuals with impaired fasting glucose (IFG) or impaired glucose tolerance (IGT) have an increased risk of progression to Type 2 diabetes mellitus. The objective of this review was to quantify the effectiveness of lifestyle, pharmacological and surgical interventions in reducing the progression to Type 2 diabetes mellitus in people with IFG or IGT. A systematic review was carried out. A network meta-analysis (NMA) of log-hazard ratios was performed. Results are presented as hazard ratios and the probabilities of treatment rankings. 30 studies were included in the NMA. There was a reduced hazard of progression to Type 2 diabetes mellitus associated with all interventions versus standard lifestyle advice; glipizide, diet plus pioglitazone, diet plus exercise plus metformin plus rosiglitazone, diet plus exercise plus orlistat, diet plus exercise plus pedometer, rosiglitazone, orlistat and diet plus exercise plus voglibose produced the greatest effects. Lifestyle and some pharmacological interventions are beneficial in reducing the risk of progression to Type 2 diabetes mellitus. Lifestyle interventions require significant behaviour changes that may be achieved through incentives such as the use of pedometers. Adverse events and cost of pharmacological interventions should be taken into account when considering potential risks and benefits. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

The aim of this study was to investigate potential hypoglycaemic and hypolipidemic effects of Plantago ovata husk included in the diet, in healthy and diabetic rabbits. We also examined the effects of this fiber in other biochemical parameters. Two groups of 18 rabbits were used. The first group was fed with standard chow and the second with chow supplemented with Plantago ovata husk (3.5 mg/kg/day). On day 14 diabetes mellitus was induced by the intravenous administration of alloxan (80 mg/kg). After an oral glucose load (3 g), glucose, insulin, and other biochemical parameters were determined on day 14 (healthy rabbits) and on day 28 (diabetic rabbits). In healthy rabbits, fiber did not modify glucose or insulin levels but decreased significantly total cholesterol, LDL-cholesterol, atherogenic index, and glycosylated hemoglobin. In diabetic rabbits, fiber was more beneficial in mild diabetics than in severe diabetics with significant decreases in glucose levels and increases in insulin concentrations. In these animals fiber caused an important reduction in cholesterol, indicating a beneficial effect of Plantago ovata husk in diabetic rabbits. Although further studies in patients are necessary, we think that Plantago ovata husk offers interesting perspectives to be administered to patients with diabetes mellitus. PMID:23762869

Canagliflozin (CFZ) is a member of new class of glucose lowering agents, sodium-glucose co-transporter (SGLT) inhibitors, which got approval by food and drug administration. It has insulin independent action by blocking the transporter protein SGLT2 in the kidneys, resulting in urinary glucose excretion and reduction in blood glucose levels. In clinical trials, CFZ significantly decreased HbA1c level when administered either as monotherapy or as combined therapy with other anti-diabetic drugs. Intriguingly, it showed additional benefits like weight reduction and lowering of blood pressure. The commonly observed side effects were urinary and genital infections. It has exhibited favorable pharmacokinetic and pharmacodynamic profiles even in patients with renal and hepatic damage. Hence, this review purports to outline CFZ as a newer beneficial drug for type 2 diabetes mellitus. PMID:24936262

We determined, in Iranian patients with diabetes mellitus, the prevalence of inadequate glycemic control and its predictors. The data from a national population-based survey that included a random sample of 89 404 Iranian individuals in 2005 were analyzed. In that sample, 2923 diabetic subjects (age range, 25-64 years) were identified. We linked the results of their fasting plasma glucose levels with demographic and behavioral variables to determine predictors of poor glycemic control. About 57% of the subjects had a fasting plasma glucose level of > or =130 mg/dL. That percentage was comparable in male and female subjects and in literate and illiterate subjects. However, inhabitants in rural areas controlled their fasting plasma glucose level about 11% better than did subjects who lived in an urban area. We also found that control of the fasting plasma glucose level was much better in relatively younger diabetic patients. Diabetic subjects with a family history of type 2 diabetes mellitus exhibited a higher uncontrolled fasting plasma glucose level than those without positive family history of diabetes. The percentage of uncontrolled type 2 diabetes found in our study suggests that the Iranian healthcare system should devote more attention to that disorder, particularly in elderly individuals, who are more vulnerable to the complications of diabetes and control their disorder less well than do younger diabetic patients. The recent integration of diabetic care in primary healthcare systems in Iranian rural areas was found to have a promising effect on community health.

Gestational diabetes is commonly linked to development of type 2 diabetes mellitus (T2DM). There is a need to characterize metabolic changes associated with gestational diabetes in order to find novel biomarkers for T2DM. To find potential pathophysiological mechanisms and markers for progression from gestational diabetes mellitus to T2DM by studying the metabolic transition from pregnancy to postpartum. The metabolic transition profile from pregnancy to postpartum was characterized in 56 women by mass spectrometry-based metabolomics; 11 women had gestational diabetes mellitus, 24 had normal glucose tolerance, and 21 were normoglycaemic but at increased risk for gestational diabetes mellitus. Fasting serum samples collected during trimester 3 (gestational week 32±0.6) and postpartum (10.5±0.4months) were compared in diagnosis-specific multivariate models (orthogonal partial least squares analysis). Clinical measurements (e.g., insulin, glucose, lipid levels) were compared and models of insulin sensitivity and resistance were calculated for the same time period. Women with gestational diabetes had significantly increased postpartum levels of the branched-chain amino acids (BCAAs) leucine, isoleucine, and valine, and their circulating lipids did not return to normal levels after pregnancy. The increase in BCAAs occurred postpartum since the BCAAs did not differ during pregnancy, as compared to normoglycemic women. Postpartum levels of specific BCAAs, notably valine, are related to gestational diabetes during pregnancy. Copyright © 2017 Elsevier Inc. All rights reserved.

Non-enzymatic glycation of peptides and proteins by D-glucose has important implications in the pathogenesis of diabetes mellitus, particularly in the development of diabetic complications. In this report, a thorough proteomic profiling of glycated proteins was attempted by using phenylboronate affinity chromatography to enrich glycated proteins and glycated, tryptic peptides from human plasma and erythrocyte membranes. Enriched peptides were subsequently analyzed by liquid chromatography coupled with electron transfer dissociation tandem mass spectrometry, and 76 and 31 proteins were confidently identified as glycated from human plasma and erythrocyte membrane, respectively. It was observed that most of the glycated proteins can be identifiedmore » in samples from individuals with normal glucose tolerance, although samples from individuals with impaired glucose tolerance and type 2 diabetes mellitus have slightly higher numbers of glycated proteins and more glycation sites identified.« less

Nutrition and exercise in individuals with diabetes.
Zinker, B A
1999-07-01
Individuals with type 1 (insulin-dependent diabetes mellitus [IDDM]) and type 2 (non-insulin-dependent diabetes mellitus [NIDDM]) diabetes should be encouraged to exercise. Although there is an absence of consistent evidence that adaptations to routine exercise improve glucose control in type 1 diabetes, there is evidence that shows improved glucose control in individuals with type 2 diabetes. Although both groups benefit from exercise, the merit and suitability of routine exercise is measured by the extent to which the advantageous adaptive effects of regular exercise surpass the risks of a sole bout of exercise. In addition, when considering acute versus routine exercise, special considerations must be given to children with diabetes and older adults at risk for insulin resistance. Finally, a greater research focus is needed on engaging in competitive and recreational sports so that children and adults with diabetes may participate safely in activities such as baseball, swimming, basketball, soccer, and hockey.

Blood glucose may condition factor VII levels in diabetic and normal subjects.
Ceriello, A; Giugliano, D; Quatraro, A; Dello Russo, P; Torella, R
1988-12-01
Increased factor VII levels have been reported in Type 1 (insulin-dependent) diabetic subjects. A direct correlation between fasting plasma glucose and factor VII level was found to exist in both diabetic and normal subjects. Induced-hyperglycaemia was able to increase factor VII levels in both diabetic patients and normal control subjects while, when euglycaemia was achieved in diabetic patients, factor VII values returned to normal range. This study shows that the level of factor VII may be directly conditioned by circulating blood glucose and, therefore, stresses the role of hyperglycaemia in conditioning coagulation abnormalities in diabetes mellitus.

To investigate whether diabetes mellitus is associated with Parkinson-like pathology in people without Parkinson disease and to evaluate the effect of diabetes mellitus on markers of Parkinson pathology and clinical progression in drug-naive patients with early-stage Parkinson disease. We compared 25 patients with Parkinson disease and diabetes mellitus to 25 without diabetes mellitus, and 14 patients with diabetes mellitus and no Parkinson disease to 14 healthy controls (people with no diabetes mellitus or Parkinson disease). The clinical diagnosis of diabetes mellitus was confirmed by 2 consecutive fasting measurements of serum glucose levels >126 mL/dL. Over a 36-month follow-up period, we then investigated in the population with Parkinson disease whether the presence of diabetes mellitus was associated with faster motor progression or cognitive decline. The presence of diabetes mellitus was associated with higher motor scores ( p < 0.01), lower striatal dopamine transporter binding ( p < 0.05), and higher tau CSF levels ( p < 0.05) in patients with Parkinson disease. In patients with diabetes but without Parkinson disease, the presence of diabetes mellitus was associated with lower striatal dopamine transporter binding ( p < 0.05) and higher tau ( p < 0.05) and α-synuclein ( p < 0.05) CSF levels compared to healthy controls. At the Cox survival analysis in the population of patients with Parkinson disease, the presence of diabetes mellitus was associated with faster motor progression (hazard ratio = 4.521, 95% confidence interval = 1.468-13.926; p < 0.01) and cognitive decline (hazard ratio = 9.314, 95% confidence interval = 1.164-74.519; p < 0.05). Diabetes mellitus may predispose toward a Parkinson-like pathology, and when present in patients with Parkinson disease, can induce a more aggressive phenotype. © 2018 American Academy of Neurology.

Targeting hepatic glucose output in the treatment of type 2 diabetes
Rines, Amy K.; Sharabi, Kfir; Tavares, Clint D. J.; Puigserver, Pere
2017-01-01
Type 2 diabetes mellitus is characterized by the dysregulation of glucose homeostasis resulting in hyperglycemia. Although current diabetes treatments have exhibited some success in lowering blood glucose, their effect is not always sustained and their use may be associated with undesirable side effects, such as hypoglycemia. Novel diabetic drugs, which may be used in combination with existing therapies, are therefore needed. The potential of specifically targeting the liver in order to normalize blood glucose levels has not been fully exploited. Here, we review the molecular mechanisms controlling hepatic gluconeogenesis and glycogen storage, and assess the prospect of therapeutically targeting associated pathways to treat type 2 diabetes.

The mechanisms underlying the progression of diabetes mellitus and heart failure are closely intertwined, such that worsening of one condition is frequently accompanied by worsening of the other; the degree of clinical acceleration is marked when the 2 coexist. Activation of the sodium-hydrogen exchanger in the heart and vasculature (NHE1 isoform) and the kidneys (NHE3 isoform) may serve as a common mechanism that links both disorders and may underlie their interplay. Insulin insensitivity and adipokine abnormalities (the hallmarks of type 2 diabetes mellitus) are characteristic features of heart failure; conversely, neurohormonal systems activated in heart failure (norepinephrine, angiotensin II, aldosterone, and neprilysin) impair insulin sensitivity and contribute to microvascular disease in diabetes mellitus. Each of these neurohormonal derangements may act through increased activity of both NHE1 and NHE3. Drugs used to treat diabetes mellitus may favorably affect the pathophysiological mechanisms of heart failure by inhibiting either or both NHE isoforms, and drugs used to treat heart failure may have beneficial effects on glucose tolerance and the complications of diabetes mellitus by interfering with the actions of NHE1 and NHE3. The efficacy of NHE inhibitors on the risk of cardiovascular events may be enhanced when heart failure and glucose intolerance coexist and may be attenuated when drugs with NHE inhibitory actions are given concomitantly. Therefore, the sodium-hydrogen exchanger may play a central role in the interplay of diabetes mellitus and heart failure, contribute to the physiological and clinical progression of both diseases, and explain certain drug-drug and drug-disease interactions that have been reported in large-scale randomized clinical trials. © 2017 American Heart Association, Inc.

Exercise showed some potential in preventing gestational diabetes mellitus. However, the results remained controversial. We conducted a systematic review and meta-analysis to evaluate the impact of exercise during pregnancy on gestational diabetes mellitus. PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the influence of exercise during pregnancy on gestational diabetes mellitus were included. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. The primary outcome was the incidence of gestational diabetes mellitus. Meta-analysis was performed using random-effect model. Six RCTs involving 2164 patients were included in the meta-analysis. Compared with control intervention, exercise intervention was associated with significantly decreased incidence of gestational diabetes mellitus (Std. mean difference = 0.59; 95%CI = 0.39-.88; p = .01), but had no effect on gestational age at birth (Std. mean difference = -0.03; 95%CI = -0.12 to 0.07; p = .60), the number of preterm birth (OR = 0.85; 95%CI = 0.43-1.66; p = .63), glucose 2-h post-OGTT (Std. mean difference = -1.02; 95%CI = -2.75 to 0.71; p = .25), birth weight (Std. mean difference = -0.13; 95%CI = -0.26 to 0.01; p = .06), and Apgar score less than 7 (OR = .78; 95%CI = 0.21-2.91; p = .71). Compared to control intervention, exercise intervention could significantly decrease the risk of gestational diabetes mellitus, but showed no impact on gestational age at birth, preterm birth, glucose 2-h post-OGTT, birth weight, and Apgar score less than 7.

Proprotein convertase 1/3 (PC1/3) deficiency is a very rare disease characterized by severe intractable diarrhea in the first years of life, followed by obesity and several hormonal deficiencies later. Diabetes mellitus requiring insulin treatment and diabetic ketoacidosis have not been reported in this disorder. We herein present a girl with PC1/3 deficiency who has been followed from birth to 17 years of age. She developed deficiencies of all pituitary hormones over time as well as diabetes mellitus while receiving growth hormone (GH) therapy. She was complicated with diabetic ketoacidosis during dietary management of diabetes mellitus, thus insulin treatment was initiated. Insulin requirement to regulate hyperglycemia was short-lived. Repeat oral glucose tolerance test five years later was normal. The findings of this patient show that diabetes mellitus can develop at any time during follow-up of cases with proportein convertase 1/3 deficiency especially under GH therapy. PMID:28588004

Type 2 diabetes mellitus is a complex metabolic disorder resulting from the action and interaction of many genetic and environmental factors. It has been reported that polymorphisms in genes involved in the metabolism of glucose are associated with the susceptibility to develop type 2 diabetes mellitus. Although the risk of developing type 2 diabetes mellitus increases with age, as well as with obesity and hypertension, its prevalence and incidence are different among geographical regions and ethnic groups. In Mexico, a higher prevalence and incidence has been described in the south of the country, and differences between urban and rural communities have been observed. We studied 73 individuals from Santiago Jamiltepec, a small indigenous community from Oaxaca State, Mexico. This population has shown a high prevalence of type 2 diabetes mellitus, and the aim of this study was to analyze the relationship between the Pst I (insulin gene), Nsi I (insulin receptor gene) and Gly972Arg (insulin receptor substrate 1 gene) polymorphisms and type 2 diabetes mellitus, obesity and hypertension in this population. Clinical evaluation consisted of BMI and blood pressure measurements, and biochemical assays consisted of determination of fasting plasma insulin and glucose levels. PCR and restriction enzyme digestion analysis were applied to genomic DNA to identify the three polymorphisms. From statistical analysis carried out here, individually, the Pst I, Nsi I and Gly972Arg polymorphisms were not associated with the type 2 diabetes, obese or hypertensive phenotypes in this population. Nevertheless, there was an association between the Nsi I and Pst I polymorphisms and increased serum insulin levels.

World Health Organization has predicted a worldwide rise in the prevalence of diabetes mellitus. Cote d'Ivoire is not exempted as evidenced by such factors as obesity and sedentary life style amongst others. The objective of the study was to determine the prevalence of diabetes mellitus (DM) among children and adolescents in the district of Abidjan in Cote d'Ivoire. A cross-sectional descriptive survey using a multi-stage sampling approach was conducted from March to April 2013. 1572 children and adolescents aged 02-19 years were surveyed in 687 randomly selected households in three municipalities. Capillary fasting glucose was performed in all subjects, and when abnormal was followed by an Oral Glucose Tolerance Test (OGTT). Definitions of Impaired Fasting Glucose (IFG) and DM (Diabetes Mellitus) were according to International Society for Paediatric and Adolescent Diabetes (ISPAD) Guidelines. The prevalence of DM and IFG were 0.4 % and 14.5 % respectively. There was no significant differences between patients with different glycemic status in terms of ethnicity/nationality (p = 0.98) or gender (0.079). In the rural areas, 565 (81.1 %) subjects were normoglycaemic and 132 (18.9 %) subjects hyperglycaemic while there were 773 (88.3 %) normoglycaemic subjects and 102 (11.7 %) hyperglycaemic subjects respectively from the urban areas of residence and this difference was statistically significant (p = 0.000). The prevalence of diabetes mellitus was identical (0.4 %) in the two age groups (2-9 years and 10-19 years). Seventy-seven (4.9 %) children who participated in the study had at least one diabetic parent. The proportion of participants with a diabetic father (59, 3.8. %) was twice the proportion with a diabetic mother (30,1.9 %) and this was statistically significant (p = 0.002). Only 10 out of 228 patients with IFG reported for the follow up OGTT and no impaired glucose tolerance was identified in these patients. The prevalence rate of DM among children and adolescents was 0.4 %. Nationwide awareness campaigns and prevention programmes about diabetes in childhood should be instituted and existing ones strengthened. Adequate commitment from the relevant stakeholders especially the country's ministry of health is also advocated to stem this looming epidemic.

Pancreatic β-cells secrete insulin when blood glucose levels become high; however, when β-cells are chronically exposed to hyperglycemia, β-cell function gradually deteriorates, which is known as β-cell glucose toxicity. In the diabetic state, nuclear expression of the pancreatic transcription factors pancreatic and duodenal homeobox 1 (PDX-1) and v-Maf musculoaponeurotic fibrosarcoma oncogene family, protein A (MafA) is decreased. In addition, incretin receptor expression in β-cells is decreased, which is likely involved in the impairment of incretin effects in diabetes. Clinically, it is important to select appropriate therapy for type 2 diabetes mellitus (T2DM) so that β-cell function can be preserved. In addition, when appropriate pharmacological interventions against β-cell glucose toxicity are started at the early stages of diabetes, β-cell function is substantially restored, which is not observed if treatment is started at advanced stages. These observations indicate that it is likely that downregulation of pancreatic transcription factors and/or incretin receptors is involved in β-cell dysfunction observed in T2DM and it is very important to start appropriate pharmacological intervention against β-cell glucose toxicity in the early stages of diabetes. © 2015 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

Aims and Objectives: The purpose of this study was to estimate and assess any correlation between random capillary blood glucose (RCBG) and unstimulated whole salivary glucose (UWSG), as well as to estimate various salivary parameters, such as flow rate, pH, buffering capacity, and the influence of these factors on the oral health status in type 2 diabetes mellitus (DM). Materials and Methods: Sixty individuals suffering from type 2 DM and 40 healthy individuals in the age group of 30–60 years were included in the study. RCBG was estimated using glucometer and UWSG was estimated using photocolorimeter. Salivary parameters such as flow rate, pH, and buffering capacity were assessed using GC® Saliva kit. Oral health status was recorded using the Russell's periodontal index (RPI) and the Decayed Missing Filled Teeth (DMFT) index. The Statistical Package for the Social Sciences version 16 was used for statistical analysis. Results: Type 2 diabetics had higher mean values for RCBG levels and UWSG. Type 2 diabetics had low mean salivary flow rate, pH, and buffering capacity. Type 2 diabetics had higher mean values for RPI. Conclusion: Among the salivary factors studied, salivary glucose significantly influenced the periodontal status in Type 2 diabetics. PMID:28316946

Diabetes mellitus complicates 3-5% of all pregnancies and is a major cause of perinatal morbidity and mortality. The diet and insulin have revolutionized the care related with pregnancy complicated by diabetes mellitus. To report the management experience in patients with diabetes and pregnancy at the Instituto Materno Infantil, Estado de Mexico. A descriptive, retrospective, observational and cross-sectional study of pregnant women with diabetes and pregnancy was conducted from 2003 to 2004. We included 55 pregnant women who had: gestational diabetes 30 (54.4%), pregestational diabetes 24 (43.6%), and carbohydrate intolerance 1 (1.8%); every one of them were controlled either with diet, insulin or both. The mean age was 30.6, 80% with family history of type 2 diabetes mellitus, 9% gestational diabetes. Gestational diabetes was diagnosed in 33.3% by abnormal 50 g glucose screening and 46.6% with oral glucose tolerance test (OGTT). The main complications among the patients were urinary disease (61.3%) and the major fetal malformation were those related with cardiovascular disease (9.09%). The most frequent mode of delivery was cesarean section (58%) and birth weight was of 3,146 g. The main risk factors identified among women in the study group were as follow: More than 25 years of age and family history of diabetes mellitus. We observed a progressive increase in the insulin dosage. The most consistent complications among the patients were urinary infection and the major fetal malformation was cardiovascular disease.

Elevated urinary albumin excretion (UAE) is more frequent in patients with the metabolic syndrome or insulin resistance. Whether UAE predicts the development of diabetes mellitus, independently of the presence or the development of the metabolic syndrome, is unclear, in particular, in women. We prospectively assessed the association between baseline UAE and subsequent diabetes mellitus in participants selected from the general population. Four thousand and seventy-four nondiabetic patients (aged 30-64 years) included in the Data from an Epidemiological Study on the Insulin Resistance syndrome Study had a baseline UAE. Among them, 3851 patients had complete data regarding diabetes mellitus. Diabetes mellitus occurred in 171 out of 3851 patients during the 9-year follow-up (132/2056 men and 39/1795 women). UAE was associated with diabetes mellitus in a dose-dependent manner in men [as compared to men with UAE<9 mg/l, hazard ratios were 1.81 (P=0.0160), 1.83 (P=0.0134), 2.31 (P=0.0008) and 4.43 (P=0.0005) for men with UAE: 9-12 mg/l, 12-19 mg/l, 20-200 mg/l and >200 mg/l, respectively] but not in women; the association was more marked after exclusion of men with baseline impaired fasting glucose [hazard ratios were 3.28 (P=0.0007), 3.08 (P=0.0012), 3.27 (P=0.0022), 9.23 (P<0.0001), respectively]. The association remained significant after adjustments on BMI, sporting activity, diet, smoking, waist circumference, insulin and homeostasis model assessment of insulin resistance, lipids, C-reactive protein and family of history of diabetes mellitus. Adjustment on the first 3-year change in weight, glucose, insulin and homeostasis model assessment of insulin resistance did not modify the results. Elevated UAE predicts the 9-year risk of diabetes mellitus in men, independent of baseline or early development of metabolic abnormalities or insulin resistance.

Although the prevalence rates of hypertension (HTN) and diabetes mellitus are slowing in some high-income countries, HTN and diabetes mellitus remain as the two major risk factors for atherosclerotic cardiovascular disease (CVD), the leading cause of death in the United States and worldwide. We aimed to observe the association of HTN and diabetes mellitus with all-cause and CVD mortality in older white adults. All community-dwelling Rancho Bernardo Study participants who were at least 55 years old and had carefully measured blood pressure and plasma glucose from 75-g oral glucose tolerance test at the baseline visit (1984-1987, n = 2186) were followed up until death or the last clinic visit in 2013 (median 14.3 years, interquartile range 8.4-21.3). In unadjusted analyses, diabetes mellitus was associated with all-cause mortality [hazard ratio 1.40, 95% confidence interval (CI) 1.23-1.60] and CVD mortality (hazard ratio 1.67, 95% CI 1.39-2.00); HTN with all-cause mortality [hazard ratio 1.93 (1.73-2.15)] and CVD mortality [hazard ratio 2.45 (2.10-2.93)]. After adjustment for cardiovascular risk factors, including age, BMI, triglycerides, HDL-cholesterol, smoking, exercise, and alcohol consumption, diabetes mellitus was associated with CVD mortality only (hazard ratio 1.25, P = 0.0213). Conversely, HTN was associated with both all-cause (hazard ratio 1.34, P < 0.0001) and CVD mortality (hazard ratio 1.40, P = 0.0003). Having both diabetes mellitus and HTN was associated with all-cause (hazard ratio 1.38, P = 0.0002) and CVD mortality (hazard ratio 1.70, P < 0.0001). We report the novel finding that HTN is more strongly associated with all-cause and CVD mortality than diabetes mellitus. Having both confers a modest increase in the hazards for these types of mortality.

[Pentosidine: a new biomarker in diabetes mellitus complications].
Morales, Sonia; García-Salcedo, José A; Muñoz-Torres, Manuel
2011-03-19
Diabetes mellitus causes an increase of morbidity and mortality. Advanced glycosilation end products (AGE) are formed by non-enzymatic glycation between proteins and reducing sugars as glucose. Oxidative reactions (glycoxidations) are essential for the formation of some AGE, for example pentosidine. Increased concentrations of pentosidine can be found in pathological conditions associated with hyperglycaemia and also related to increased oxidative stress. In individuals with diabetes mellitus, pentosidine formation and accumulation is developed at an accelerated rate in cells without insulin control for glucose uptake. Pentosidine has a pivotal role in diabetic complications, probably as a consequence of the diverse properties of this compound, which alters the structure and function of molecules in biological systems. The following review discusses the alterations in the concentration of pentosidine in the body, particularly in relation to changes occurring in diabetes and its complications such as vascular and bone disease, nephropathy, neuropathy and retinopathy. Novel therapeutic approaches which can prevent or ameliorate the toxic effects of AGE in the initiation and progression of diabetic complications are reviewed. Copyright © 2009 Elsevier España, S.L.

Although several data suggest that serum uric acid (SUA) predicts future development of metabolic abnormalities, the evidence is not conclusive in Mediterranean populations. A total of 3200 individuals were randomly selected from the residents of Monza (North Italy) to be representative of its general population for sex and age (25-74 years). The participation rate was 64%. At baseline and 10 years later, we measured waist circumference, office blood pressure, fasting blood glucose, serum triglycerides, serum HDL cholesterol and SUA. The analysis was carried out in individuals without metabolic syndrome at baseline (N = 1192) when looking for incidence of metabolic syndrome, without impaired fasting glucose (IFG) at baseline (N = 1320) when looking for incidence of IFG and without diabetes mellitus at baseline (N = 1352) when looking for incidence of diabetes mellitus. Adjusting for confounders, a 1-SD increase of baseline SUA was not associated with and increased risk of new-onset metabolic syndrome, but with new-onset IFG [relative risk (RR) = 1.26, confidence interval (CI) 1.06-1.5, P = 0.01]. It was associated with a 29% increased risk of new-onset diabetes mellitus, that was more than twice in the highest as compared with the lowest quartile of baseline SUA (RR = 1.29, CI 0.98-1.7, P = 0.07, and RR = 2.16, CI 0.95-4.88, P = 0.07). Focusing the analysis on the individuals with age above the median value, SUA increase was significantly associated with an increased risk of new-onset metabolic syndrome, IFG and diabetes mellitus. SUA increase is associated with an increased risk of developing IFG and, in the population fraction with age above the median value, also metabolic syndrome and diabetes mellitus.

The main manifestation of hyperglycaemia during pregnancy is gestational diabetes mellitus. It can herald diabetes mellitus type 2 and its deleterious long-term effects, such as hypertension and cardiovascular disease. The aim of this study was to assess diastolic function in women with gestational diabetes mellitus, one of the first signs of future cardiovascular disease. A total of 21 women with gestational diabetes mellitus and 23 healthy pregnant women (control group) between 34 and 37 weeks of gestation underwent echocardiographic assessment. The diagnosis of gestational diabetes mellitus was made in agreement with the American Diabetes Association criteria. Echocardiographic images obtained were analysed according to the criteria of the American Society of Echocardiography. Data were analysed using Pearson correlation coefficient, analysis of variance and Student's t-test. Women with gestational diabetes mellitus had higher posterior wall and interventricular septum thickness, increased left ventricular mass and left ventricular mass index, lower early diastolic annular velocity and early diastolic annular velocity/late diastolic annular velocity ratio. There was a positive correlation between left ventricular mass index and fasting glucose and pregnancy body mass index. Patients with gestational diabetes mellitus seem to have a different diastolic profile as well as a mildly dysfunctional pattern on echocardiogram, which may show a need for greater glycaemic control. © The Author(s) 2015.

Diabetes mellitus diagnosed during the first 2 years of life differs from the disease in older children regarding its causes, clinical characteristics, treatment options and needs in terms of education and psychosocial support. Over the past decade, new genetic causes of neonatal diabetes mellitus have been elucidated, including monogenic β-cell defects and chromosome 6q24 abnormalities. In patients with KCNJ11 or ABCC8 mutations and diabetes mellitus, oral sulfonylurea offers an easy and effective treatment option. Type 1 diabetes mellitus in infants is characterized by a more rapid disease onset, poorer residual β-cell function and lower rate of partial remission than in older children. Insulin therapy in infants with type 1 diabetes mellitus or other monogenic causes of diabetes mellitus is a challenge, and novel data highlight the value of continuous subcutaneous insulin infusion in this very young patient population. Infants are entirely dependent on caregivers for insulin therapy, nutrition and glucose monitoring, which emphasizes the need for appropriate education and psychosocial support of parents. To achieve optimal long-term metabolic control with low rates of acute and chronic complications, continuous and structured diabetes care should be provided by a multidisciplinary health-care team.

This paper aims to investigate whether intraepidermal nerve-fibre density (IENFD) may be used as a marker of the course of neuropathy in patients with Type 2 diabetes mellitus. Skin biopsies from the distal leg were serially evaluated in a group of 30 patients with Type 2 diabetes mellitus (median age 60 years, 17 men) with a short duration of diabetes (< 3 years) and good glucose control, and in 23 age- and sex-matched controls. The time intervals between biopsies were > 2 years (median 33.8 months). Eighteen patients with Type 2 diabetes mellitus had symptoms or signs of distal symmetrical diabetic polyneuropathy, 12 had no neuropathy. At first skin biopsy, IENFD was normal in all controls and in patients without neuropathy (mean 9.5 and 7.9 fibres/mm, respectively) compared with abnormal IENFD in 77.8% in patients with polyneuropathy (mean 3.4 fibres/mm). The annual rate of intraepidermal nerve-fibre (IENF) loss expressed as a percentage of the first IENFD value in patients with diabetic polyneuropathy was significantly higher [mean (se), 11.95 (3.82)%] compared with controls [1.92 (1.81)%, P < 0.001] and similar to patients without polyneuropathy [12.16 (4.38)%]. The rate of IENF loss did not correlate with degree of glucose control. The annual rate of IENF loss in patients with Type 2 diabetes mellitus was several times higher than that of healthy participants, irrespective of the presence of signs or symptoms of diabetic polyneuropathy at initial evaluation. The change in IENFD is not linear and should be expressed as a proportion of initial IENFD to serve as a marker of the course of diabetic neuropathy. © 2015 Diabetes UK.

This study evaluated the effects of aerobic exercise performed both previously and after the induction of diabetes mellitus on changes of renal function and structure in streptozotocin-induced diabetic rats. Female wistar rats were divided into five groups: sedentary control (C + Se); trained control (C + Ex); sedentary diabetic (D + Se); trained diabetic (D + Ex) and previously trained diabetic (D + PEx). The previous exercise consisted of treadmill running for four weeks before the induction of diabetes mellitus. After induction of diabetes mellitus with streptozotocin, the D + PEx, D + Ex and C + Ex groups were submitted to eight weeks of aerobic exercise. At the end of the training protocol, we evaluate the serum glucose, insulin and 17β-estradiol levels, renal function and structure, proteinuria, and fibronectin, collagen IV and transforming growth factor beta 1 (TGF-β1) renal expressions. Induction of diabetes mellitus reduced the insulin and did not alter 17β-estradiol levels, and exercise did not affect any of these parameters. Previous exercise training attenuated the loss of body weight, the blood glucose, the increase of glomerular filtration rate and prevented the proteinuria in the D + PEx group compared to D + Se group. Previous exercise also reduced glomerular hypertrophy, tubular and glomerular injury, as well as the expressions of fibronectin and collagen IV. These expressions were associated with reduced expression of TGF-β1. In conclusion, our study shows that regular aerobic exercise especially performed previously to induction of diabetes mellitus improved metabolic control and has renoprotective action on the diabetic kidney.

Glucose transport across the enterocyte brush border membrane by sodium/glucose cotransporter-1 (SGLT1, coded by Slc5a1) is the rate-limiting step for intestinal glucose transport. The relevance of SGLT1 expression in predisposition to diabetes mellitus and to obesity was investigated in dogs. Cultured Caco-2/TC7 cells were shown to express SGLT1 in vitro. A 2-kbp fragment of the Slc5a1 5' flanking region was cloned from canine genomic DNA, ligated into reporter gene plasmids, and shown to drive reporter gene expression in these cells above control (P < 0.001). To determine the effect of the 3 known SNPs in this region on promoter function, new promoter/reporter constructs (all permutations of these 3 SNPs) were created by site-directed mutagenesis. No significant differences in promoter function were seen, suggesting that these SNPs do not have a significant effect on the constitutive transcription of SGLT1 mRNA in dogs. A search for novel SNPs in this region in dogs was made in 2 breeds predisposed to diabetes mellitus (Samoyed and cairn terrier), 2 breeds that rarely develop diabetes (boxer and German shepherd), and 2 breeds predisposed to obesity (Labrador retriever and cocker spaniel). The Slc5a1 5' flanking region was amplified from 10 healthy individuals of each of these breeds by high-fidelity PCR with the use of breed-labeled primers and sequenced by pyrosequencing. The sequence of the Slc5a1 5' flanking region in all individuals of all breeds tested was identical. On this evidence, variations in Slc5a1 promoter sequence between dogs do not influence the pathogenesis of diabetes mellitus or obesity in these breeds. Copyright © 2013 Elsevier Inc.

Clinical studies have revealed that testosterone supplementation had a positive effect on glucose homeostasis in type 2 diabetes mellitus (T2DM), but did not address how testosterone supplementation affected insulin responsiveness in the liver, a key glucose homeostatic organ. In this study, we aimed to study the effect of testosterone supplementation on hepatic insulin responsiveness and glucose homeostasis through liver in male high-fat diet-induced T2DM mice. Testosterone treatment to T2DM animals showed reduced hepatic glucose output. Testosterone inhibited the insulin signaling in liver, thus increased insulin resistance. However, testosterone treatment inactivated GSK3α independent of PI3K/AKT pathway and inhibited FOXO1 By interaction of androgen receptor to FOXO1 and downregulated PEPCK, causing repression of gluconeogenic pathway, which is otherwise upregulated in T2DM, resulted in better glucose homeostasis.

Malnutrition has been shown to impair insulin sensitivity, but it is not known whether this effect has any impact on coexisting diabetes. Insulin sensitivity was therefore studied using the glucose clamp technique in rats with chronic nutritional deprivation superimposed on mild streptozocin (STZ) diabetes mellitus. In pair-feeding experiments, 4-week-old littermate rats were either allowed ad libitum access to food or restricted to 50% of ad libitum intake for 8 weeks, and were injected with STZ 40 mg/kg intraperitoneally halfway through the experiment. Fasting plasma glucose (FPG) was similar in both groups of rats, but fasting plasma insulin (FPI) was lower in the undernourished group (P = .016). Undernourished rats were significantly more insulin resistant during euglycemic hyperinsulinemia of the same degree, with glucose disposal rate being impaired by 50% as compared with that in ad libitum-fed diabetic littermates (24.4 +/- 2.8 v 51.5 +/- 4.4 mumol/kg/min, P = .0008). The insulin sensitivity index was significantly lower in the undernourished group (3.03 +/- 0.32 v 5.67 +/- 0.6, P = .0057). The results show that chronic undernutrition markedly reduces insulin sensitivity in rats with mild STZ diabetes. This is further evidence that chronic undernutrition is a deleterious modifying influence on coexisting diabetes mellitus. It suggests that the insulin resistance of malnutrition-related diabetes mellitus (MRDM) could potentially be an acquired defect mediated by the coexistent undernutrition, rather than a "distinctive" feature that is intrinsically unique to this diabetic syndrome.

To explore the clinical profile and laboratory changes in three patients with diabetes mellitus treated with recombinant human growth hormone (rhGH). Results showed that the patient in the first case was diagnosed as T1DM according to the classical course of disease, weight loss, polyuria, polydispsia, polyphagia, and positive GAD-Ab. The second patient’s plasma glucose and urine glucose were at a high level, then stored immediately with the negative OGTT. But, the level of insulin increased significantly suggesting there is insulin resistance. In the last case, fasting plasma glucose level was higher than 7.0 mmol/l several times. The level of HbA1c increased. In an oral glucose tolerance test (OGTT), fasting glucose > 7.0 mmol/l, plasma glucose < 7.8 mmol/l two hours after a 75 g oral glucose load. We postulate that the higher than expected incidence of type 2 diabetes mellitus with GH treatment may be an acceleration of the disorder in predisposed individuals. The rhGH therapy may eventually induce transitory glucose metabolic disorder in a very small proportion of patients, which was restored gradually after the discontinuance of rhGH. PMID:26221404

To investigate the effects of daily chromium picolinate supplementation on serum measures of glucose tolerance and insulin sensitivity in patients at high risk for type 2 diabetes mellitus. We conducted a randomized, double-blind, placebo-controlled, modified cross-over clinical trial with 6-month sequences of intervention and placebo followed by a 6-month postintervention assessment. Adult patients with impaired fasting glucose, impaired glucose tolerance, or metabolic syndrome were enrolled. Participants received 6-month sequences of chromium picolinate or placebo at 1 of 2 dosages (500 or 1000 mcg daily). Primary outcome measures were change in fasting plasma glucose, 2-hour plasma glucose during oral glucose tolerance testing, fasting and 2-hour insulin, and homeostasis model assessment of insulin resistance (HOMA-IR). Secondary outcomes included anthropometric measures, blood pressure, endothelial function, hemoglobin A1c, lipids, and urinary microalbumin. Fifty-nine participants were enrolled. No changes were seen in glucose level, insulin level, or HOMA-IR (all P>.05) after 6 months of chromium at either dosage level (500 mcg or 1000 mcg daily) when compared with placebo. None of the secondary outcomes improved with either chromium dosage compared with placebo (P>.05). Chromium supplementation does not appear to ameliorate insulin resistance or impaired glucose metabolism in patients at risk for type 2 diabetes and thus is unlikely to attenuate diabetes risk.

The therapeutic armamentarium for the treatment of hyperglycemia in type 2 diabetes mellitus is still inadequate. We are currently witnessing the introduction of a new mode of hypoglycemic treatment through induction of glycosuria to decrease the availability of the metabolic substrate, i.e. glucose. Clinical trials have shown that sodium-glucose co-transporter-2 (SGLT2) inhibitors are as efficacious as other oral hypoglycemic drugs. This article discusses the basic features of this new treatment concept and the efficacy and safety of this new drug group. Copyright © 2013 Elsevier España, S.L. All rights reserved.

Type 2 diabetes has a long pre clinical asymptomatic phase. Early detection may delay or arrest disease progression. The Diabetes Mellitus and Vascular health initiative (DMVhi) was initiated as a prospective longitudinal cohort study on the prevalence of undiagnosed Type 2 diabetes and prediabetes, diabetes risk and cardiovascular risk in a cohort of Irish adults aged 45-75 years. Members of the largest Irish private health insurance provider aged 45 to 75 years were invited to participate in the study. already diagnosed with diabetes or taking oral hypoglycaemic agents. Participants completed a detailed medical questionnaire, had weight, height, waist and hip circumference and blood pressure measured. Fasting blood samples were taken for fasting plasma glucose (FPG). Those with FPG in the impaired fasting glucose (IFG) range had a 75gm oral glucose tolerance test performed. 122,531 subjects were invited to participate. 29,144 (24%) completed the study. The prevalence of undiagnosed diabetes was 1.8%, of impaired fasting glucose (IFG) was 7.1% and of impaired glucose tolerance (IGT) was 2.9%. Dysglycaemia increased among those aged 45-54, 55-64 and 65-75 years in both males (10.6%, 18.5%, 21.7% respectively) and females (4.3%, 8.6%, 10.9% respectively). Undiagnosed T2D, IFG and IGT were all associated with gender, age, blood pressure, BMI, abdominal obesity, family history of diabetes and triglyceride levels. Using FPG as initial screening may underestimate the prevalence of T2D in the study population. This study is the largest screening study for diabetes and prediabetes in the Irish population. Follow up of this cohort will provide data on progression to diabetes and on cardiovascular outcomes.

Chronic exposure to arsenic has been associated with the development of diabetes mellitus (DM), a disease characterized by hyperglycemia resulting from dysregulation of glucose homeostasis. This review summarizes four major mechanisms by which arsenic induces diabetes, namely inhibition of insulin-dependent glucose uptake, pancreatic β-cell damage, pancreatic β-cell dysfunction and stimulation of liver gluconeogenesis that are supported by both in vivo and in vitro studies. Additionally, the role of polymorphic variants associated with arsenic toxicity and disease susceptibility, as well as epigenetic modifications associated with arsenic exposure, are considered in the context of arsenic-associated DM. Taken together, in vitro, in vivo and human genetic/epigenetic studies support that arsenic has the potential to induce DM phenotypes and impair key pathways involved in the regulation of glucose homeostasis.

Previous studies suggested that reduced muscular strength was one of the potential predictor of prevalence of diabetes mellitus. The purpose of this study was to investigate the association between toe flexor strength (TFS) and handgrip strength (HGS) and the prevalence of diabetes mellitus. Cross-sectional analysis was conducted using data from 1,390 Japanese males (35-59 years). TFS and HGS were measured and medical examinations undertaken. The prevalence of diabetes mellitus was defined as fasting blood glucose ≥126 mg/dL, glycated hemoglobin ≥6.5% (48 mmol/mol), and/or current use of anti-diabetes mellitus drugs. A total of 114 participants had diabetes mellitus. TFS in participants with diabetes mellitus was significantly lower than that in persons not suffering from diabetes mellitus but HGS was not. Odds ratio (OR) and 95% confidence interval (CI) per 1-standard deviation-increase in muscular strength measurements for the prevalence of diabetes mellitus were obtained using a multiple logistic regression model. Prevalence of diabetes mellitus was inversely related to TFS (OR 0.769, 95% CI 0.614-0.963), TFS/body mass (BM) (0.696, 0.545-0.889) and TFS/body mass index (BMI) (0.690, 0.539-0.882) after adjustment of covariates. Such associations were not observed in HGS (OR 0.976, 95% CI 0.773-1.232), HGS/BM (0.868, 0.666-1.133) or HGS/BMI (0.826, 0.642-1.062). These results suggested that poor TFS was associated with an increased prevalence of diabetes mellitus independent of visceral fat accumulation, but HGS was not, in middle-aged males. TFS may be a better marker for the prevalence of diabetes mellitus than HGS.

The aim of the study was to analyze the correlations between the expression of glucose transporters GLUT-1, GLUT-4, and GLUT-9 in human term placenta and selected maternal and fetal parameters in pregnancies complicated by diabetes mellitus (DM). 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 pregestational DM (PGDM) (n = 6). Computer-assisted quantitative morphometry of stained placental sections was performed to determine the expression of selected glucose transporter proteins. For the purposes of correlation analysis, the following parameters were selected: type of diabetes, gestational age, maternal prepregnancy body mass index (BMI), gestational weight gain, third trimester glycated hemoglobin concentration, placental weight, fetal birth weight (FBW) as well as ultrasonographic indicators of fetal adiposity, including subscapular (SSFM), abdominal (AFM), and midthigh (MTFM) fat mass measurements. In the PGDM group, the analysis demonstrated positive correlations between the placental expression of GLUT-1, GLUT-4, and GLUT-9 and FBW, AFM, and SSFM measurements (p < .05). Similarly in the GDMG2 patients positive correlations between GLUT-4 expression, FBW and SSFM were observed (p < .05). In the multivariate regression analysis, only the type of diabetes and FBW were significantly associated with GLUTs expression (p < .001). In addition, maternal prepregnancy BMI significantly contributed to GLUT-1 expression (p < .001). The study results revealed that placental expression of GLUT-1, GLUT-4, and GLUT-9 may be involved in the intensification of the fetal growth in pregnancies complicated by GDM/PGDM.

Blood glucose variability is common in healthcare and it is not related or influenced by diabetes mellitus. To minimise the risk of high blood glucose in critically ill patients, Stochastic Targeted Blood Glucose Control Protocol is used in intensive care unit at hospitals worldwide. Thus, this study focuses on the performance of stochastic modelling protocol in comparison to the current blood glucose management protocols in the Malaysian intensive care unit. Also, this study is to assess the effectiveness of Stochastic Targeted Blood Glucose Control Protocol when it is applied to a cohort of diabetic patients. Retrospective data from 210 patients were obtained from a general hospital in Malaysia from May 2014 until June 2015, where 123 patients were having comorbid diabetes mellitus. The comparison of blood glucose control protocol performance between both protocol simulations was conducted through blood glucose fitted with physiological modelling on top of virtual trial simulations, mean calculation of simulation error and several graphical comparisons using stochastic modelling. Stochastic Targeted Blood Glucose Control Protocol reduces hyperglycaemia by 16% in diabetic and 9% in nondiabetic cohorts. The protocol helps to control blood glucose level in the targeted range of 4.0-10.0 mmol/L for 71.8% in diabetic and 82.7% in nondiabetic cohorts, besides minimising the treatment hour up to 71 h for 123 diabetic patients and 39 h for 87 nondiabetic patients. It is concluded that Stochastic Targeted Blood Glucose Control Protocol is good in reducing hyperglycaemia as compared to the current blood glucose management protocol in the Malaysian intensive care unit. Hence, the current Malaysian intensive care unit protocols need to be modified to enhance their performance, especially in the integration of insulin and nutrition intervention in decreasing the hyperglycaemia incidences. Improvement in Stochastic Targeted Blood Glucose Control Protocol in terms of u en model is also a must to adapt with the diabetic cohort. Copyright © 2018 Elsevier B.V. All rights reserved.

ABSTRACT Type 2 diabetes mellitus is a complex metabolic disease and its pathogenesis involves abnormalities in both peripheral insulin action and insulin secretion. Previous in vitro data showed that insulin receptor isoform A, but not B, favours basal glucose uptake through its specific association with endogenous GLUT1/2 in murine hepatocytes and beta cells. With this background, we hypothesized that hepatic expression of insulin receptor isoform A in a mouse model of type 2 diabetes could potentially increase the glucose uptake of these cells, decreasing the hyperglycaemia and therefore ameliorating the diabetic phenotype. To assure this hypothesis, we have developed recombinant adeno-associated viral vectors expressing insulin receptor isoform A (IRA) or isoform B (IRB) under the control of a hepatocyte-specific promoter. Our results demonstrate that in the long term, hepatic expression of IRA in diabetic mice is more efficient than IRB in ameliorating glucose intolerance. Consequently, it impairs the induction of compensatory mechanisms through beta cell hyperplasia and/or hypertrophy that finally lead to beta cell failure, reverting the diabetic phenotype in about 8 weeks. Our data suggest that long-term hepatic expression of IRA could be a promising therapeutic approach for the treatment of type 2 diabetes mellitus. PMID:27562101

Glycated keratin allows the monitoring of average tissue glucose exposure over previous weeks. In the present study, we wanted to explore if near-infrared (NIR) spectroscopy could be used as a non-invasive diagnostic tool for assessing glycation in diabetes mellitus. A total of 52 patients with diabetes mellitus and 107 healthy subjects were enrolled in this study. A limited number (n=21) of nails of healthy subjects were glycated in vitro with 0.278 mol/L, 0.556 mol/L and 0.833 mol/L glucose solution to study the effect of glucose on the nail spectrum. Consequently, the nail clippings of the patients were analyzed using a Thermo Fisher Antaris II Near-IR Analyzer Spectrometer and near infrared (NIR) chemical imaging. Spectral classification (patients with diabetes mellitus vs. healthy subjects) was performed using partial least square discriminant analysis (PLS-DA). In vitro glycation resulted in peak sharpening between 4300 and 4400 cm-1 and spectral variations at 5270 cm-1 and between 6600 and 7500 cm-1. Similar regions encountered spectral deviations during analysis of the patients' nails. Optimization of the spectral collection parameters was necessary in order to distinguish a large dataset. Spectra had to be collected at 16 cm-1, 128 scans, region 4000-7500 cm-1. Using standard normal variate, Savitsky-Golay smoothing (7 points) and first derivative preprocessing allowed for the prediction of the test set with 100% correct assignments utilizing a PLS-DA model. Analysis of protein glycation in human fingernail clippings with NIR spectroscopy could be an alternative affordable technique for the diagnosis of diabetes mellitus.

Diabetes Mellitus is now a prevalent disease in both developed and developing countries. Overweight/obesity and hypertension are potential modifiable risk factors for diabetes mellitus and persist during the course of the disease. This study was aimed at reporting the prevalence of overweight/obesity and systemic hypertension and their association to blood glucose levels in persons with diabetes mellitus attending a diabetic clinic in Ghanaian Teaching Hospital. This cross-sectional study was conducted among 100 previously diagnosed diabetes mellitus patients attending a diabetic clinic at the Tamale Teaching Hospital, Ghana. Anthropometric variables of age, weight and height were measured with appropriate instruments, computed into BMI and classified according to WHO classifications. Systolic and diastolic blood pressures were measured by an appropriate instrument and classified by WHO standards. Fasting plasma glucose levels of the study participants were recorded from their personal health folder. All data was analysed by GraphPad prism version 5. In general, 7.0% of the participants were underweight and 32.0% were overweight or obese. The mean±SD weight, height and BMI of the participants were 67.53±13.32, 1.68±0.12 and 24.18±5.32. Twenty-one percent of the studied participants were hypertensive. Mean±SD fasting plasma glucose of 7.94±2.82 was observed among the diabetic patients. As the prevalence of hyperglycaemia was higher among patients aged ≤40 years (88.9% vs. 75.8%), normoglycaemia (11.1% vs. 24.2%) was higher among those over 40 years. The differences were not significant. The prevalence of hyperglycaemia was significantly higher in participants with overweight/obese (0.0% vs. 41.6%, p<0.0001) than those with underweight (26.1% vs. 1.3%, p=0.0005) and normal weight (73.9% vs. 57.1%, p=0.2228). A high prevalence of overweight/obesity and systemic hypertension was found. Hyperglycaemia was more prevalent among overweight/obese participants. Copyright © 2014 Diabetes India.

This study evaluated the protective effect of Lentinus edodes in rats with streptozotocin-induced gestational diabetes mellitus (STZ-GDM) when administered orally. The rats received from the 1st to the 19th day of gestation daily doses of 100 or 200 mg/kg of lyophilized and reconstituted L. edodes; the animals in the saline control group and diabetic control group received a saline solution (DS). Gestational diabetes mellitus was induced by streptozotocin (80 mg/kg, administered intraperitoneally) on the fourth day of pregnancy; blood glucose > 180 mg/dL was considered to indicate STZ-GDM. L. edodes reduced catalase in plasma. We also observed reduced glucose in plasma, urea, triglycerides, and aspartate aminotransferase. There was a decrease in preimplantation loss when compared with the DS group. The doses of L. edodes used here had a protective effect on the preimplantation parameters in STZGDM. However, the mushroom was not able to reverse the deleterious effects caused by streptozotocin throughout the evolution of pregnancy.

Rate of postpartum screening and progression to glucose intolerance (diabetes and/or pre-diabetes) in Asian women with prior GDM and risk factors of diversion to abnormal glucose tolerance were reviewed. We searched Pub Med, Cochrane Library, Web of Science, EMBASE, and Ovid data base. About 1300 studies were screened and 27 articles were selected. Meta-analysis using Comprehensive Meta -Analysis software was conducted. All results were reported at the pooled ORs and 95% CI. Quantitative heterogeneity (I 2 ) was assessed. To estimate the variances between studies, the statistical method "tau-squared" was applied. Statistical models like fixed effect or Mantel-Haenszel, and random effect (REM) or Dersimonian-laird were used for the analysis and integration of results. Rate of glucose testing ranged from 13.1% to 81.9%. Prevalence of pre-diabetes was 3.9%-50.9%. Diabetes was reported in 2.8%-58% of women with history of gestational diabetes based on length of follow-up. Factor associated with postpartum diabetes mellitus included family History of diabetes mellitus, gestational age at diagnosis of GDM, insulin use during pregnancy and pre-pregnancy BMI. Rate of postpartum screening in most of the Asian countries population is sub-optimal, in spite of high rate of glucose intolerance in this high risk group of women. Risk factors of progression to pre-diabetes and diabetes are similar to previous reported in developed countries. Copyright © 2017 Diabetes India. All rights reserved.

Glucose control is the cornerstone of Diabetes Mellitus (DM) treatment. Although self-regulation using capillary glycemia (SRCG) still remains the best procedure in clinical practice, continuous glucose monitoring systems (CGM) offer the possibility of continuous and dynamic assessment of interstitial glucose concentration. CGM systems have the potential to improve glycemic control while decreasing the incidence of hypoglycemia but the efficiency, compared with SRCG, is still debated. CGM systems have the greatest potential value in patients with hypoglycemic unawareness and in controlling daily fluctuations in blood glucose. The implementation of continuous monitoring in the standard clinical setting has not yet been established but a new generation of open and close loop subcutaneous insulin infusion devices are emerging making insulin treatment and glycemic control more reliable.

Therapeutic Lifestyle Changes for Diabetes Mellitus.
Levesque, Celia
2017-12-01
Diabetes mellitus is a common chronic disease affecting approximately 9% of the United States population. Successful management of diabetes demands constant self-management on the part of the patient. The patient has to balance diabetes medications, blood glucose monitoring, food intake, physical activity, and management of diabetes-related acute and chronic complications. The patient is often bombarded with misinformation from friends, relatives, and such sources as the Internet and social media. This article discusses the current recommendations for diabetes self-management education and skills including medical nutrition therapy, physical activity, smoking cessation, and assessment for diabetes distress.

Recent studies have reported an increase in the prevalence of obesity and metabolic syndrome in children and adolescents. However, few have focused how diabetes mellitus and metabolic syndrome together in parents can influence on obesity and metabolic disturbances in offspring. To know the risk obesity and metabolic disturbance in children, adolescents, and young adults whose parents have diabetes mellitus and metabolic syndrome. A comparative survey was made in healthy children of parents with diabetes mellitus and metabolic syndrome compared with offspring of healthy parents. We performed anthropometry and evaluated blood pressure, glucose, total cholesterol, HDL cholesterol, and triglycerides levels in plasma. We registered parent antecedents to diabetes mellitus and metabolic syndrome and investigated the prevalence of overweight, obesity, and metabolic disturbances in offspring. We studied 259 subjects of 7 to 20 years of age. The prevalence of overweight and obesity was 27% and 37%, respectively. The highest proportion of BMI >95th of the entire group was found in offspring with both diabetic parents. Glucose and total cholesterol levels were lower in the group with healthy parents compared with the group with diabetic mother and metabolic syndrome but with healthy father. HDL cholesterol was higher in the group with both healthy parents than in the group with diabetic mother and metabolic syndrome but healthy father. The offspring of parents with diabetes plus metabolic syndrome showed higher proportion of variables related to metabolic syndrome compared with healthy parents.

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.

To investigate the prevalence rates of diabetes mellitus and its associated risk factors in children with Han, Uygur and Kazak ethnicities in Xinjiang. A cross-sectional random samples involving aged 0 - 17 years were carried out to analyze the prevalence rates and associated risk factors of diabetes mellitus in children of Han, Uigur and Kazak ethnicities from 3 prefectures (Hetian, Kashi and Fuhai) in Xinjiang Autonomous Regions. Diabetes mellitus and impaired fasting glucose (IFG) were defined by the China Diabetes Prevention and Control Standard set in 2007. Data was collected through filling in the questionnaires and results from physical examination and laboratory tests. The total prevalence rates of IFG and diabetes mellitus were 0.68% and 0.09%, respectively. Data from logistic regression analysis suggested that overweight and obesity were risk factors for diabetes mellitus in children from Xinjiang, with odds ratio values as 2.844 and 3.963, respectively. Children with Han, Uygur and Kazak ethnicities in Xinjiang had an overall standardized prevalence rates of diabetes mellitus. IFG were 0.57% and 1.35% lower than the 2004 data from children at same age groups in Beijing and the whole nation, also 0.19% lower then the national rate of 5 - 17 years-old children juvenile diabetes.

To reveal the effect of hyperuricaemia on endothelial function in normoglycaemic first-degree relatives of type 2 diabetes mellitus. In all, 40 first-degree relatives of type 2 diabetes mellitus with hyperuricaemia, 40 first-degree relatives of type 2 diabetes mellitus with normouricaemia and 35 healthy subjects without diabetic family history were recruited in this study. Anthropometric parameters as well as blood pressure, blood lipids, fasting blood glucose, fasting insulin, C-reactive protein, tumour necrosis factor-α and interleukin-6 were measured. Insulin resistance was assessed with homoeostasis model assessment index-insulin resistance index. To assess endothelial function, high-resolution ultrasonography was used for measuring flow- and nitroglycerine-mediated brachial artery vasodilation. When compared with control, flow-mediated dilation was lower in first-degree relatives with or without hyperuricaemia (both p < 0.001). When compared with first-degree relative subjects with normouricaemia, there were lower flow-mediated dilation ( p < 0.001) and higher levels of uric acid ( p < 0.001), fasting blood glucose ( p < 0.001), C-reactive protein ( p = 0.001), tumour necrosis factor-α ( p < 0.001) and interleukin-6 ( p < 0.001) in first-degree relative subjects with hyperuricaemia. Flow-mediated dilation was found to be negatively related to uric acid ( r = -0.597, p < 0.001). Stepwise multiple regressions demonstrated that uric acid was a significant determinant of flow-mediated dilation independent of other variables in first-degree relatives of type 2 diabetes mellitus (β = -0.677, p < 0.001; confidence interval: -0.010 to -0.006). Further endothelial dysfunction is found in normoglycaemic first-degree relatives of type 2 diabetes mellitus complicated with hyperuricaemia.

We studied the possible relationship between nitric oxide (NO) production and insulin resistance in patients with type 2 diabetes mellitus. Urine NO metabolites (NOx) were measured as an index for NO production by HPLC combined with a Cd column, Griess reaction and a spectrophotometer in 403 healthy control subjects and 102 hospitalized patients with type 2 diabetes. Glucose infusion rate (GIR) was measured as a reverse index for insulin resistance by euglycemic glucose clamp study using an artificial pancreas in 20 of 102 diabetic patients. Urine NOx was lower in the patients with type 2 diabetes than in healthy control subjects (mean+/-SE: 3.18 +/-0.02 versus 3.25 +/-0.01 log[-micromol/gCr], p<0.01). Urine NOx was correlated with body mass index (BMI) in 102 diabetic patients (r= -0.372, p<0.001), but not related to either age, sex, fasting plasma glucose, HbA1c or blood pressure. Urine NOx was correlated with GIR independent of BMI in 20 diabetic patients (r=0.774, P<0.0001). These findings suggest that NO production is closely related with insulin resistance in patients with type 2 diabetes.

For Ramadan fasting, observing Muslims do not eat or drink between sunrise and sunset during Ramadan, Islam's holy month of the year according to the lunar calendar. In 2011, fasting patients with diabetes fasted for an average of 16.5 hours per day, having 2 meals between sunset and sunrise for a month. We aimed to evaluate the impact of extended fasting on glucose regulation and observe possible complications of extended fasting in type 2 diabetes mellitus patients. We conducted a randomized, retrospective, observational study. Patients who presented at the Diabetes Clinic during the 15 days before and after Ramadan in August 2011 Istanbul, whose hemoglobin A1c, fasting plasma glucose, postprandial plasma glucose, weight and height value examinations and follow-up were completed were included in the study. Seventy-six diabetes patients who fasted during Ramadan (fasting group) and 71 patients with diabetes who did not fast (non-fasting group) were included in the study. These two groups with similar demographic characteristics were compared before and after Ramadan. HbA1c, fasting and postprandial plasma glucose, body mass index, weight and adverse events were evaluated. No statistically significant difference was observed among the fasting and the non-fasting groups. There was no difference between the pre and post-Ramadan values of the fasting group. We could not find any negative effects of extended fasting on glucose regulation of patients with diabetes who are using certain medications. No serious adverse event was observed. We failed to demonstrate benefits of increasing the number of meals in patients with diabetes.

Diabetes and impaired fasting glucose, as well as cognitive impairment, are common in the elderly. Although several cross-sectional studies have demonstrated the influence of diabetes on cognitive impairment, only a few longitudinal studies have assessed the relationship between diabetes, impaired fasting glucose and cognitive decline in non-demented elderly community dwellers, by means of extensive neuropsychological batteries. The present study assesses the relationship between baseline diabetes, impaired fasting glucose (IFG) and 2- year evolution of memory, attention and executive performance in a sample of non-demented elderly subjects. Population-based cohort study [(PROgnostic indicator OF cardiovascular and cerebrovascular events (PROOF)]. One hundred and sixty-three community dwellers aged 65 years without dementia at recruitment. Memory, attention and executive performance. A significant association was observed between baseline diabetes mellitus and a higher 2-year decline in the Trial Making Test B and Stroop test exploring attention and executive function. This effect remained significant after adjusting for age, gender, education, anxiety and depressive symptoms, as well as other cardiovascular risk factors (F=2.41; p=0.007). Instead, no relationship was observed between IFG and cognitive decline. Our study showed that, in a sample of elderly non-demented community dwellers, diabetes mellitus (but not IFG) is associated with a higher decline in selective attention and executive functioning. These results emphasize the importance of detecting and man- aging diabetes and impaired fasting glucose, in order to prevent cognitive impairment and dementia.

Magnesium ion, as important cation in the human body, involved in various enzymatic reactions, glucose transport and insulin release. Now diabetes mellitus and diabetic complications have become important public health problems around the world. This paper explores the association between concentration levels of serum magnesium and common complications and comorbidities of diabetes mellitus and other biochemical indexes. There are 1217 eligible patients selected from 14,317 cases of diabetic hospitalization patients from January 2010 to December 2011. Random forest algorithm was applied to assess the importance of various biochemical indexes and to perform diabetic complications prediction. The research results showed that low concentration of serum magnesium and four common diabetic complications - diabetic retinopathy, diabetic nephropathy, diabetic neuropathy and diabetic macroangiopathy - exists association, but no obvious correlation with other comorbidities like hypertension. The specific factors of four common diabetic complications were selected from the biochemical indexes to provide a reference direction for further research.

Mouse Models of Type 2 Diabetes Mellitus in Drug Discovery.
Baribault, Helene
2016-01-01
Type 2 diabetes is a fast-growing epidemic in industrialized countries, associated with obesity, lack of physical exercise, aging, family history, and ethnic background. Diagnostic criteria are elevated fasting or postprandial blood glucose levels, a consequence of insulin resistance. Early intervention can help patients to revert the progression of the disease together with lifestyle changes or monotherapy. Systemic glucose toxicity can have devastating effects leading to pancreatic beta cell failure, blindness, nephropathy, and neuropathy, progressing to limb ulceration or even amputation. Existing treatments have numerous side effects and demonstrate variability in individual patient responsiveness. However, several emerging areas of discovery research are showing promises with the development of novel classes of antidiabetic drugs.The mouse has proven to be a reliable model for discovering and validating new treatments for type 2 diabetes mellitus. We review here commonly used methods to measure endpoints relevant to glucose metabolism which show good translatability to the diagnostic of type 2 diabetes in humans: baseline fasting glucose and insulin, glucose tolerance test, insulin sensitivity index, and body type composition. Improvements on these clinical values are essential for the progression of a novel potential therapeutic molecule through a preclinical and clinical pipeline.

In addition to macro and microvascular complications that are associated with the disease, hyperglycaemia is also a risk factor for several oral complications. The aim of this study is to establish a relationship between dental caries in patients with type 1 diabetes mellitus treated with multiple insulin injections and that of individuals without diabetes. It is also an aim to characterize the oral hygiene habits of this population. An observational clinical study of analytical and cross-sectional nature was conducted. Thirty patients with type 1 diabetes mellitus and 30 individuals without diabetes were observed and questioned about information regarding their medical history. Oral examination was conducted according to the standards of the World Health Organization and ICDAS was used for caries detection. Statistical analysis was performed and the significance level was set at 5%. Patients with diabetes mellitus showed similar caries levels to that of individuals without diabetes. Patients with diabetes mellitus had a higher dental plaque index. Only 10% of the patients having episodes of nocturnal hypoglycaemia brush their teeth after glucose intake. Although there's some controversy in the literature regarding the prevalence of caries in patients with diabetes mellitus, the results are in agreement with a great number of studies. However, patients with diabetes mellitus have a higher plaque index which can be associated with a higher risk for developing certain oral pathologies. No statistically significant association was found between type 1 diabetes mellitus and dental caries.

The prevalence of diabetes is increasing worldwide, and most of the cases are type 2 diabetes mellitus. The relationship between type 2 diabetes mellitus and obesity is well established, and surgical treatment is widely used for obese patients with type 2 diabetes mellitus. The aim was to present current knowledge about the possible mechanisms responsible for glucose control after surgical procedures and to review the surgical treatment results. Medical literature was searched for the articles presenting the impact of surgical treatment on glycemic control, long-term results, and possible mechanisms of action among obese individuals with type 2 diabetes mellitus. Remission of type 2 diabetes mellitus after bariatric surgery depends on the definition of the remission used. Complete remission rate after surgery with the new criteria is lower than was considered before. Randomized controlled studies demonstrate that surgery is superior to best medical treatment for the patients with type 2 diabetes mellitus. The recurrence of type 2 diabetes mellitus after bariatric surgery is observed in up to 40% of cases with ≥ 5 years of follow-up. Despite the recurrence of type 2 diabetes mellitus in this group, better glycemic control and lower risk of macrovascular complications are present. Incretin effects on glycemic control after bariatric surgery are well described, but the role of other possible mechanisms (bile acids, microbiota, intestinal gluconeogenesis) in humans is unclear. Surgery is an effective treatment of type 2 diabetes mellitus in obese patients. The most optimal surgical procedure for the treatment of obese patients with type 2 diabetes mellitus is still to be established. More research is needed to explore the mechanisms of glycemic control after bariatric surgery. © The Finnish Surgical Society 2015.

Background Women with gestational diabetes mellitus (GDM) are at high risk for type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD); continuous life-style intervention, especially diet, is central to managing T2DM and CVD. However, little is known about the dietary patterns of women with GDM after delivery. The goal of this study was to compare the eating habits and food intakes of women diagnosed with GDM during the early postpartum period. Methods We performed a 75 g oral glucose tolerance test (OGTT) in 184 women with GDM between 6 and 12 weeks after delivery. Based on the results of the OGTT, the subjects were divided into three groups according to the American Diabetes Association criteria; normal glucose tolerance (NGT) (n=100), pre-diabetes (n=73), and diabetes mellitus (DM) (n=11). Eating habits and usual food intake after delivery were investigated using a questionnaire, based on 24 hour-recall, which was administered by a trained dietitian. The daily intake data were analyzed using CAN Pro 3.0. Blood tests were performed pre- and post-delivery. Results Eating habits were not significantly different among the three groups. However, animal fat consumption was significantly different among the three groups. The intake ratio of fat calories to total calories was also significantly higher in the pre-diabetes and DM groups. Conclusion Although diet in the period 6 to 12 weeks postpartum did not influence glucose level, it may be important to educate women with GDM about the risks of excessive animal fat intake during pregnancy and the postpartum period in order to prevent later onset of T2DM.

The prevalence of type 2 diabetes mellitus in developing countries like Ghana continues to rise. This study seeks to assess the risk factors of type 2 diabetes mellitus in a Ghanaian setting. An unmatched case-control study among patients receiving care at the out-patient departments of the two major hospitals in the Ho Municipality. Patients diagnosed with type 2 diabetes mellitus were recruited. Appropriate controls with similar ages who were also patients receiving care at the out-patient department of these hospitals were recruited. Both cases and controls were administered a questionnaire that comprises of standardized and validated tools. These tools include WHO STEPs instrument, general practice physical activity questionnaire and rapid eating and activity assessment for patients. Additionally, the research participants were made to undergo physical examinations for weight, height, waist circumference and laboratory testing of fasting venous blood to assess the biochemical factors of interest namely fasting blood glucose and fasting lipids. Analysis of data was done using STATA version 11. A total of 136 (48 cases and 88 controls) participants of which 95 [39 (81.25%) cases and 56 (63.64%) controls] respondents underwent laboratory testing for fasting blood glucose and fasting blood lipid (total cholesterol, HDL cholesterol and triglycerides). Participants were aged between 35 and 62 years. This study reveals a number of risk factors for type 2 diabetes mellitus. Individuals in the middle socio-economic class have a greater risk of developing type 2 diabetes mellitus with an OR of 5.03 (p < 0.003; 95% CI 1.71-14.74). Eating large quantities/servings of fruits per seating provides protection against development of type 2 diabetes mellitus. A low physical activity level is a valid determinant of type 2 diabetes mellitus irrespective of body mass index, socio-economic level or place of residence. Individuals within the middle socio-economic level, who are physically inactive and do not consume large amounts of fruit are at greatest risk of developing type 2 diabetes mellitus. Living in a rural setting is attendant with high levels of physical activity this tends to protect rural residents from type 2 diabetes mellitus. Physical activity level confounds the relationship between place of residence and development of type 2 diabetes mellitus. Local policies should be realigned to attract individual of the middle socio-economic level to live in rural areas where they are more likely to be both physically active and consume more fruits thus averting the risks of developing T2DM.

The very presence of an implanted sensor (a foreign body) causes changes in the adjacent tissue that may alter the analytes being sensed. The objective of this study was to investigate changes in glucose availability and local tissue metabolism at the sensor-tissue interface in patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM). Microdialysis was used to model implanted sensors. Capillary glucose and subcutaneous (sc) microdialysate analytes were monitored in five T1DM and five T2DM patients. Analytes included glucose, glycolysis metabolites (lactate, pyruvate), a lipolysis metabolite (glycerol), and a protein degradation byproduct (urea). On eight consecutive days, four measurements were taken during a period of steady state blood glucose. Microdialysate glucose and microdialysate-to-blood-glucose ratio increased over the first several days in all patients. Although glucose recovery eventually stabilized, the lactate levels continued to rise. These trends were explained by local inflammatory and microvascular changes observed in histological analysis of biopsy samples. Urea concentrations mirrored glucose trends. Urea is neither produced nor consumed in sc tissue, and so the initially increasing urea trend is explained by increased local capillary presence during the inflammatory process. Pyruvate in T2DM microdialysate was significantly higher than in T1DM, an observation that is possibly explained by mitochondrial dysfunction in T2DM. Glycerol in T2DM microdialysate (but not in T1DM) was higher than in healthy volunteers, which is likely explained by sc insulin resistance (insulin is a potent antilipolytic hormone). Urea was also higher in microdialysate of patients with diabetes mellitus compared to healthy volunteers. Urea is a byproduct of protein degradation, which is known to be inhibited by insulin. Therefore, insulin deficiency or resistance may explain the higher urea levels. To our knowledge, this is the first histological evaluation of a human tissue biopsy containing an implanted glucose monitoring device. Monitoring metabolic changes at a material-tissue interface combined with biopsy histology helped to formulate an understanding of physiological changes adjacent to implanted glucose sensors. Microdialysate glucose trends were similar over 1-week in T1DM and T2DM; however, differences in other analytes indicated wound healing and metabolic activities in the two patient groups differ. We propose explanations for the specific observed differences based on differential insulin insufficiency/resistance and mitochondrial dysfunction in T1DM versus T2DM. © 2010 Diabetes Technology Society.

Objectives To study if there is any relationship about higher cutoff values for 100 g oral glucose tolerance test and the need for insulin in women diagnosed with gestational diabetes. Materials and Methods This is a retrospective population-based study of 201 women diagnosed with Gestational Diabetes Mellitus (GDM) between January 2012 and June 2014 in the area of Oviedo, Asturias, Spain. According to diagnostic criteria recommended by GEDE, NDDG, gestational diabetes is diagnosed if two or more plasma glucose levels meet or exceed the following threshold: fasting glucose of 105 mg/dl, 1-h 190 mg/dl, 2-h 165 mg/dl, or 3-h 145 mg/dl. We aim to know if there is any relationship between higher cutoffs and insulin requirement. Results 36 out of 201 patients (17.91%) needed insulin to achieve the targets of blood glucose control. There were no differences in mean maternal age and birthweights. Fasting blood glucose levels were significantly higher in women with further need for insulin than those who only needed diet and exercise (p < 0.001). Also, blood glucose levels 2 h after the oral glucose intake were statistically different between the two groups (p 0.032). AUC for fasting glucose value was the highest according to ROC curve. Conclusions Fasting cutoff vales for 100 g oral glucose tolerance test are consistently higher in women diagnosed with Gestational Diabetes that further needed insulin to achieve adequate blood glucose control. The positive predictive value of fasting glucose value 105 mg/dl on OGTT was 81.1%, whereas for the cut-off 95 mg/dl it was 54.0%.

The aim of this study was to analyse possible associations between caries increments and selected caries determinants in children with type 1 diabetes mellitus and their age- and sex-matched non-diabetic controls, over 2 years. A total of 63 (10-15 years old) diabetic and non-diabetic pairs were examined for dental caries, oral hygiene and salivary factors. Salivary flow rates, buffer effect, concentrations of mutans streptococci, lactobacilli, yeasts, total IgA and IgG, protein, albumin, amylase and glucose were analysed. Means of 2-year decayed/missing/filled surface (DMFS) increments were similar in diabetics and their controls. Over the study period, both unstimulated and stimulated salivary flow rates remained significantly lower in diabetic children compared to controls. No differences were observed in the counts of lactobacilli, mutans streptococci or yeast growth during follow-up, whereas salivary IgA, protein and glucose concentrations were higher in diabetics than in controls throughout the 2-year period. Multivariable linear regression analysis showed that children with higher 2-year DMFS increments were older at baseline and had higher salivary glucose concentrations than children with lower 2-year DMFS increments. Likewise, higher 2-year DMFS increments in diabetics versus controls were associated with greater increments in salivary glucose concentrations in diabetics. Higher increments in active caries lesions in diabetics versus controls were associated with greater increments of dental plaque and greater increments of salivary albumin. Our results suggest that, in addition to dental plaque as a common caries risk factor, diabetes-induced changes in salivary glucose and albumin concentrations are indicative of caries development among diabetics.

This study was a case control cross sectional study that was conducted on 50 patients with type 1 diabetes mellitus and 30 controls without diabetes. The mean age of patients was 10.02 years. Oral sugar tolerance tests using glucose, sucrose and honey and measurement of fasting and postprandial serum C-peptide levels were done for all subjects in three separate sittings. The glycemic index (GI) and the peak incremental index (PII) were then calculated for each subject. Honey, compared to sucrose, had lower GI and PII in both patients and controls (P < 0.01). In both patients and controls, the increase in the level of C-peptide after honey was significant when compared with either glucose or sucrose (P < 0.01). Because of its possible stimulatory effect on diseased beta cells, honey might be considered in future therapeutic trials targeting beta cells of pancreas. Copyright © 2012 Elsevier Ltd.

Maternal outcomes and follow-up after gestational diabetes mellitus.
Kim, C
2014-03-01
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. © 2013 The Author.

Nursing management of the person with diabetes mellitus. Part 2.
Nair, Muralitharan
Diabetes mellitus (DM) is a syndrome of a relative or absolute lack of insulin resulting in hyperglycaemia. Patients with type 1 diabetes need insulin to regulate their blood glucose levels, while for patients with type 2 diabetes, weight loss and dietary management may be sufficient in controlling blood glucose levels (Porth, 2005). People from black and ethnic minority groups are six time more likely to develop the condition than their white counterparts (Department of Health, 2005a). Department of Health guidelines (2005a) give clear guidelines for healthcare workers in caring for patients with diabetes. There is no known cure for diabetes, however management of patients with diabetes include dietary management, physical activity, oral antidiabetic agents and insulin regimen. Care can also be complex as some of the patients may suffer from other long-term conditions, such as coronary artery disease. Part 2 of this article discusses the nurse's need to adhere to the National Institute for Clinical Excellence guidelines (2002a, 2004) in the management for type 1 and type 2 diabetes.

Ensete superbum ameliorates renal dysfunction in experimental diabetes mellitus.
Sreekutty, M S; Mini, S
2016-01-01
Hyperglycemia mediated oxidative stress plays a key role in the pathogenesis of diabetic complications like nephropathy. In the present study, we evaluated the effect of ethanolic extract of Ensete superbum seeds (ESSE) on renal dysfunction and oxidative stress in streptozotocin-induced diabetic rats. Glucose, HbA1c, total protein, albumin, renal function markers (urea, uric acid and creatinine), and lipid peroxidation levels were evaluated. Renal enzymatic and non-enzymatic antioxidants were examined along with renal histopathological study. ESSE (400 mg/kg BW t) administration reduced glucose and HbA1c, and improved serum total protein and albumin in diabetic rats. ESSE in diabetic rats recorded decrement in renal function markers and renal lipid peroxidation products along with significant increment in enzymatic and non-enzymatic antioxidants. Renal morphological abnormalities of diabetic rats were markedly ameliorated by E. superbum. These results suggest that the antioxidant effect of E. superbum could ameliorate oxidative stress and delay/prevent the progress of diabetic nephropathy in diabetes mellitus.

Gestational diabetes mellitus: Screening with fasting plasma glucose.
Agarwal, Mukesh M
2016-07-25
Fasting plasma glucose (FPG) as a screening test for gestational diabetes mellitus (GDM) has had a checkered history. During the last three decades, a few initial anecdotal reports have given way to the recent well-conducted studies. This review: (1) traces the history; (2) weighs the advantages and disadvantages; (3) addresses the significance in early pregnancy; (4) underscores the benefits after delivery; and (5) emphasizes the cost savings of using the FPG in the screening of GDM. It also highlights the utility of fasting capillary glucose and stresses the value of the FPG in circumventing the cumbersome oral glucose tolerance test. An understanding of all the caveats is crucial to be able to use the FPG for investigating glucose intolerance in pregnancy. Thus, all health professionals can use the patient-friendly FPG to simplify the onerous algorithms available for the screening and diagnosis of GDM - thereby helping each and every pregnant woman.

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.

Regulation of hepatic glucose metabolism in health and disease
Petersen, Max C.; Vatner, Daniel F.; Shulman, Gerald I.
2017-01-01
The liver is crucial for the maintenance of normal glucose homeostasis — it produces glucose during fasting and stores glucose postprandially. However, these hepatic processes are dysregulated in type 1 and type 2 diabetes mellitus, and this imbalance contributes to hyperglycaemia in the fasted and postprandial states. Net hepatic glucose production is the summation of glucose fluxes from gluconeogenesis, glycogenolysis, glycogen synthesis, glycolysis and other pathways. In this Review, we discuss the in vivo regulation of these hepatic glucose fluxes. In particular, we highlight the importance of indirect (extrahepatic) control of hepatic gluconeogenesis and direct (hepatic) control of hepatic glycogen metabolism. We also propose a mechanism for the progression of subclinical hepatic insulin resistance to overt fasting hyperglycaemia in type 2 diabetes mellitus. Insights into the control of hepatic gluconeogenesis by metformin and insulin and into the role of lipid-induced hepatic insulin resistance in modifying gluconeogenic and net hepatic glycogen synthetic flux are also discussed. Finally, we consider the therapeutic potential of strategies that target hepatosteatosis, hyperglucagonaemia and adipose lipolysis. PMID:28731034

Gestational diabetes mellitus is one of the most common complications of pregnancy. Physical activity is associated with a lower risk of type 2 diabetes mellitus. A recent meta-analysis study suggested that more research is needed to investigate the type, duration and intensity of physical activity that can help to reduce the risk of gestational diabetes mellitus. The present study aimed to understand the association between physical activity and gestational diabetes mellitus through comparing the type and intensity of physical activity performed by pregnant females with gestational diabetes and healthy pregnant females in the first 20 weeks of their pregnancy. In the current case-control study, 100 pregnant females with gestational diabetes mellitus as the case group and 100 pregnant females as the non-diabetic control group were recruited. The age range of the participants was 18 - 40 years with the gestation of 20 - 28 weeks. To diagnose gestational diabetes mellitus using the criteria introduced by carpenter and coustan females with abnormal glucose challenge test (> 140 mg/dL) were asked to perform the three-hour 100 g oral glucose tolerance test. The details of physical activity were collected by a modified version of the pregnancy physical activity questionnaire. Anthropometric and relevant data were recorded for all of the participants. Data were analyzed by SPSS version 21. Risk estimates were obtained by logistic regression and adjusted for confounders. Females who had low total physical activity according to the pregnancy physical activity questionnaire during early pregnancy were at a significantly higher risk of developing gestational diabetes mellitus (OR = 4.12, 95% CI (2.28 - 7.43), P = 0.001) compared to the ones who reported higher levels of physical activity. Moreover, after adjusting for age, body mass index (BMI), gravidity and a family history of diabetes, females with low physical activity in the domain of transportation activity during 20 weeks of pregnancy were at a significantly higher risk of developing gestational diabetes mellitus. The statistical findings indicate that females with the low intensity of sedentary, light and moderate physical activity are at a higher risk of developing gestational diabetes mellitus (OR 2.32; 95% CI 1.21-4.43, P = 0.010, OR 6.26; 95% CI 2.95 - 13.30, P = 0.001 and OR 6.73; 95% CI 3.15 - 14.38, P = 0.001) compared to females with a higher intensity of sedentary, light and moderate physical activity. The amount and intensity of physical activity during pregnancy is associated with a lower risk of gestational diabetes mellitus. As a result, the pregnant Iranian females have to be encouraged to do regular daily physical activity during pregnancy, if there is no specific contraindication to it.

Ping, Zhang; Aiqun, Ma; Jiwu, Li; Liang, Shao
2017-04-06
Inflammation plays an important role in heart failure and diabetes mellitus. Traditional serum markers have limited predictive value in heart failure and diabetes. TNFR1 and TNFR2 (TNFR1/2) have been proven to be strongly associated with heart failure and diabetes complications. This study aimed to assess the association of sTNFR1 and sTNFR2 levels and incidental HF risk in diabetes patients.We detected the mRNA, protein, and serum expression of TNFR1/2, their downstream signaling pathway protein NF-kB, and JNK expression and some traditional serum inflammatory markers in a heart failure group without diabetes mellitus or abnormal glucose tolerance (n = 84), a diabetes mellitus group without heart failure (n = 86), and a heart failure with diabetes mellitus group (n = 86).TNFR1/2 were significantly higher in patients with heart failure and diabetes mellitus based on mRNA expression to protein expression and serum expression. However, there were no differences in mRNA, protein, and serum levels of TNFR1/2 between the HF group and DM group. Furthermore, there were no differences between the groups in some traditional serum inflammatory markers.This study demonstrated higher expressions of TNFR, NF-kB, and JNK in patients with heart failure and diabetes mellitus. Compared with traditional serum markers, TNFR1 and TNFR2 are associated with heart failure risk in type 2 diabetes mellitus patients.

To compare the blood glucose-lowering effect of a highly viscous fiber blend (VFB) added to a starchy snack on postprandial glycemia between healthy participants and participants with diabetes mellitus. Ten healthy participants (4 men and 6 women, aged 28+/-2.6 years, body mass index [BMI], 24.3+/-0.8 kg/m(2)) and 9 participants with diabetes mellitus type 2 (3 men and 6 women, aged 68+/-3.8 years, BMI 28.8+/-1.2 kg/m(2)) on four separate occasions took either 50 g available carbohydrates as control biscuits, biscuits with 10 g of highly viscous fiber blend, white bread with 12 g of margarine, or white bread alone. Postprandial blood glucose response, glycemic index (GI), and palatability were determined. Mean (95% confidence interval) GI values of the viscous fiber blend biscuits were 26 (16-36) and 37 (27-47) GI units for healthy participants and participants with diabetes mellitus, respectively. These values were significantly lower than those of white bread, white bread with 12 g of margarine, and control biscuits (P<0.001, paired t test) both in healthy participants (GI 100, 108 [57-159], and 101 [44-158], respectively) and participants with diabetes mellitus (GI 100, 103 [79-127], and 94 [78-110], respectively). Viscous fiber blend significantly reduced the glycemic index by 74% (7.4 GI units/g of fiber) in healthy participants and by 63% (6.3 GI units/g of fiber) in participants with diabetes. The GI did not differ between control meals in both healthy participants and participants with diabetes. There were no significant differences in palatability among the types of meals, although participants with diabetes found the viscous fiber blend biscuits more palatable (P=0.002, t test). Viscous fiber blend is a very potent and palatable soluble fiber addition to a starchy snack, which is able to reduce the glycemic response to a similar extent in both healthy participants and individuals with diabetes mellitus. Biscuits with low GI, and possibly other viscous fiber blend fortified starchy foods, may potentially be a useful replacement of high GI snack foods in the diet.

Diabetes mellitus is characterized by chronically elevated blood glucose levels accelerated by a progressive decline of insulin-producing β-cells in the pancreatic islets. Although medications are available to transiently adjust blood glucose to normal levels, the effects of current drugs are limited when it comes to preservation of a critical mass of functional β-cells to sustainably maintain normoglycemia. In this review, we recapitulate recent evidence on the role of pancreatic N-methyl-D-aspartate receptors (NMDARs) in β-cell physiology, and summarize effects of morphinan-based NMDAR antagonists that are beneficial for insulin secretion, glucose tolerance and islet cell survival. We further discuss NMDAR-mediated molecular pathways relevant for neuronal cell survival, which may also be important for the preservation of β-cell function and mass. Finally, we summarize the literature for evidence on the role of NMDARs in the development of diabetic long-term complications, and highlight beneficial pharmacologic aspects of NMDAR antagonists in diabetic nephropathy, retinopathy as well as neuropathy. © 2017 John Wiley & Sons Ltd.

Modulation of Glucose Transporter Protein by Dietary Flavonoids in Type 2 Diabetes Mellitus
Hajiaghaalipour, Fatemeh; Khalilpourfarshbafi, Manizheh; Arya, Aditya
2015-01-01
Diabetes mellitus (DM) is a metabolic diseases characterized by hyperglycemia due to insufficient or inefficient insulin secretory response. This chronic disease is a global problem and there is a need for greater emphasis on therapeutic strategies in the health system. Phytochemicals such as flavonoids have recently attracted attention as source materials for the development of new antidiabetic drugs or alternative therapy for the management of diabetes and its related complications. The antidiabetic potential of flavonoids are mainly through their modulatory effects on glucose transporter by enhancing GLUT-2 expression in pancreatic β cells and increasing expression and promoting translocation of GLUT-4 via PI3K/AKT, CAP/Cb1/TC10 and AMPK pathways. This review highlights the recent findings on beneficial effects of flavonoids in the management of diabetes with particular emphasis on the investigations that explore the role of these compounds in modulating glucose transporter proteins at cellular and molecular level.

Patient compliance and tight glycemic control have been demonstrated to improve outcome in pregnancies complicated by gestational diabetes mellitus. The use of advanced technological tools, including smartphone-based platforms, to improve medical care and outcomes has been demonstrated in various fields of medicine, but only a few small studies were performed with gestational diabetes mellitus patients. We aimed to study the impact of introducing a smartphone-based daily feedback and communication platform between gestational diabetes mellitus patients and their physicians, on patient compliance, glycemic control, pregnancy outcome, and patient satisfaction. This is a prospective, single-center, randomized controlled trial. Newly diagnosed gestational diabetes mellitus patients presenting to our multidisciplinary diabetes-in-pregnancy clinic were randomized to: (1) routine biweekly prenatal clinic care (control group); or (2) additional daily detailed feedback on their compliance and glycemic control from the clinic team via an application installed on their smartphone (smartphone group). The primary outcome was patient compliance defined as the actual blood glucose measurements/instructed measurements ×100. The secondary outcomes included diabetes-control parameters, pregnancy, and neonatal outcomes. The study was adequately powered to detect a 20% difference in patient compliance, based on a preliminary phase that demonstrated 70% baseline compliance to glucose measurements. A total of 120 newly diagnosed gestational diabetes mellitus patients were analyzed. The 2 groups did not differ in terms of age, parity, education, body mass index, family history, maternal comorbidities, oral glucose tolerance test values, and hemoglobin A1C at randomization. The smartphone group demonstrated higher level of compliance (84 ± 0.16% vs 66 ± 0.28%, P < .001); lower mean blood glucose (105.1 ± 8.6 mg/dL vs 112.6 ± 7.4 mg/dL, P < .001); lower rates of off-target measurements both fasting (4.7 ± 0.4% vs 8.4 ± 0.6%, P < .001) and 1-hour postprandial (7.7 ± 0.8% vs 14.3 ± 0.8%, P < .001); and a lower rate of pregnancies requiring insulin treatment (13.3% vs 30.0%, P = .044). The rates of macrosomia, neonatal hypoglycemia, shoulder dystocia, and other delivery and neonatal complications did not differ between the groups. Patients in the smartphone group reported excellent satisfaction from the use of the application and from their overall prenatal care. Introduction of a smartphone-based daily feedback and communication platform between gestational diabetes mellitus patients and the multidisciplinary diabetes-in-pregnancy clinic team improved patient compliance and glycemic control, and lowered the rate of insulin treatment.

To examine the validity of International Classification of Disease, version 10 (ICD-10) codes for gestational diabetes mellitus in administrative databases (outpatient and inpatient), and in a clinical perinatal database (Alberta Perinatal Health Program), using laboratory data as the 'gold standard'. Women aged 12-54 years with in-hospital, singleton deliveries between 1 October 2008 and 31 March 2010 in Alberta, Canada were included in the study. A gestational diabetes diagnosis was defined in the laboratory data as ≥2 abnormal values on a 75-g oral glucose tolerance test or a 50-g glucose screen ≥10.3 mmol/l. Of 58 338 pregnancies, 2085 (3.6%) met gestational diabetes criteria based on laboratory data. The gestational diabetes rates in outpatient only, inpatient only, outpatient or inpatient combined, and Alberta Perinatal Health Program databases were 5.2% (3051), 4.8% (2791), 5.8% (3367) and 4.8% (2825), respectively. Although the outpatient or inpatient combined data achieved the highest sensitivity (92%) and specificity (97%), it was associated with a positive predictive value of only 57%. The majority of the false-positives (78%), however, had one abnormal value on oral glucose tolerance test, corresponding to a diagnosis of impaired glucose tolerance in pregnancy. The ICD-10 codes for gestational diabetes in administrative databases, especially when outpatient and inpatient databases are combined, can be used to reliably estimate the burden of the disease at the population level. Because impaired glucose tolerance in pregnancy and gestational diabetes may be managed similarly in clinical practice, impaired glucose tolerance in pregnancy is often coded as gestational diabetes. © 2016 Diabetes UK.

SGLT2 inhibitors: a promising new therapeutic option for treatment of type 2 diabetes mellitus.
Misra, Monika
2013-03-01
Hyperglycemia is an important pathogenic component in the development of microvascular and macrovascular complications in type 2 diabetes mellitus. Inhibition of renal tubular glucose reabsorption that leads to glycosuria has been proposed as a new mechanism to attain normoglycemia and thus prevent and diminish these complications. Sodium glucose cotransporter 2 (SGLT2) has a key role in reabsorption of glucose in kidney. Competitive inhibitors of SGLT2 have been discovered and a few of them have also been advanced in clinical trials for the treatment of diabetes. To discuss the therapeutic potential of SGLT2 inhibitors currently in clinical development. A number of preclinical and clinical studies of SGLT2 inhibitors have demonstrated a good safety profile and beneficial effects in lowering plasma glucose levels, diminishing glucotoxicity, improving glycemic control and reducing weight in diabetes. Of all the SGLT2 inhibitors, dapagliflozin is a relatively advanced compound with regards to clinical development. SGLT2 inhibitors are emerging as a promising therapeutic option for the treatment of diabetes. Their unique mechanism of action offers them the potential to be used in combination with other oral anti-diabetic drugs as well as with insulin. © 2012 The Author.

To study the prevalence of diabetes mellitus and islet autoantibodies in an adult population from Southern Spain. A cross-sectional study in Southern Spain of 1226 people, age 18-65 years. Clinical data were obtained and a blood sample taken to measure autoantibodies (glutamic acid decarboxylase antibodies (GADAb), tyrosine phosphatase antibodies (IA2Ab), and insulin antibodies (IAA)). An oral glucose tolerance test (OGTT) was also given to 982 of the subjects. The overall prevalence of diabetes mellitus according to the WHO 1979 criteria was 10.9% and according to the ADA 1997 criteria it was 14.7% (8.8% were unaware of their diabetes). The prevalence of impaired fasting glucose (IFG) was 12.4% and of impaired glucose tolerance (IGT) 11.5%. The prevalence of GADAb+ in the general population was 0.9% and in the diabetic population 3.7%. There were no significant differences between groups in the prevalence of IA2Ab or IAA (both were 0.8% in the general population). Of the three autoantibodies studied, only GADAb were significantly different in the diabetic population (P=0.0006). The prevalence of Type 2 diabetes and LADA are high in the south of Spain.

There is increasing epidemiological evidence in humans which associates low birthweight with later metabolic disorders, including insulin resistance and glucose intolerance. There is evidence that nutritional and hormonal factors (e.g. maternal protein restriction, exposure to excess maternal glucocorticoids) markedly influence intra-uterine growth and development. A picture is also emerging of the biochemical and physiological mechanisms that may underlie these effects. This review focuses on recent research directed towards understanding the molecular basis of the relationship between indices of poor early growth and the subsequent development of glucose intolerance and Type 2 diabetes mellitus using animal models that attempt to recreate the process of programming via an adverse intra-uterine or neonatal environment. Emphasis is on the chain of events and potential mechanisms by which adverse adaptations affect pancreatic-beta-cell insulin secretion and the sensitivity to insulin of key metabolic processes, including hepatic glucose production, skeletal-muscle glucose disposal and adipose-tissue lipolysis. Unravelling the molecular details involved in metabolic programming may provide new insights into the pathogenesis of impaired glucoregulation and Type 2 diabetes. PMID:10903125

An increasing prevalence of diabetes is known as a main risk for human health in the last future worldwide. There is limited evidence on the potential management of type 2 diabetes mellitus using bioactive peptides from marine organisms, besides from milk and beans. We summarized here recent advances in our understanding of the regulation of glucose metabolism using bioactive peptides from natural proteins, including regulation of insulin-regulated glucose metabolism, such as protection and reparation of pancreatic β-cells, enhancing glucose-stimulated insulin secretion and influencing the sensitivity of insulin and the signaling pathways, and inhibition of bioactive peptides to dipeptidyl peptidase IV, α-amylase and α-glucosidase activities. The present paper tried to understand the underlying mechanism involved and the structure characteristics of bioactive peptides responsible for its antidiabetic activities to prospect the utilization of rich marine organism proteins.

2014-01-01
Prediabetes is a condition with blood glucose levels higher than normal but not high enough to be diagnosed as diabetes. Most people with prediabetes are asymptomatic but are considered to be at a high risk of developing heart disease and stroke. 140 students of both sexes between ages 14-18 years were given a predesigned questionnaire to obtain information on socio-economic status and family history of Diabetes mellitus. A fasting plasma glucose level was measured and 6.8% of students were in the prediabetic range (> 100 mg/dl). No significant correlation was found between fasting plasma glucose and Body Mass Index or waist to hip ratio. 41.5% of the boys and 10.3% of the girls had a family history of DM but were in euglycemic range. It is beneficial to identify people with prediabetes so that appropriate lifestyle modification may be done to prevent or postpone onset of Diabetes mellitus.

Antioxidant Role of Vitamin D in mice with Alloxan-Induced Diabetes.
Iqbal, Sarah; Khan, Saman; Naseem, Imrana
2017-12-04
The discovery of vitamin D receptors has revolutionized the understanding of vitamin D biology, which is now thought to influence a wide array of cell pathways. The antihyperglycemic actions of vitamin D involving calcium metabolism have been widely discussed, but studies are now suggesting a possibility of vitamin D-induced amelioration of oxidative stress. Despite its significance in disease pathogenesis, oxidative status remains poorly investigated with respect to vitamin D treatment in the biology of diabetes mellitus. The present study was aimed at assessing the antioxidant therapeutic potential of vitamin D in diabetes mellitus. Balb/c mice were induced to experimental diabetes with a single dose of alloxan. Following a 15-day treatment period, various parameters pertaining to glucose metabolism, oxidative stress, zinc concentration and DNA damage were analyzed. With the exception of superoxide dismutase and catalase, the antioxidant enzyme activities were slightly altered in various groups. However, improved glucose homeostasis and zinc concentration and reduced DNA damage were observed in the group treated with vitamin D. The present work accounts for the ubiquitous roles of vitamin D in various diseases and highlights its role as a therapeutic intervention in diabetes mellitus. Copyright © 2017 Diabetes Canada.

With the marked increase in the prevalence of diabetes mellitus, it was the purpose of our study to assess a potential association of time-cumulated exposure to systolic (CumSBP) and of diastolic blood pressure (CumDBP) with onset of impaired glucose tolerance and diabetes mellitus. The prospective investigation included participants of the longitudinal Kailuan Study with three baseline examinations in 2006-2007, 2008-2009 and 2010-2011, re-examination in 2012-2013, and no diabetes mellitus at baseline. Cumulative blood pressure (BP) was calculated as cumBP = [(BP 1 + BP 2 )/2 × time 1-2 ] + [(BP 2 + BP 3 )/2 × time 2-3 ]. Based on cumSBP, the study population was stratified into four groups (cumSBP < 480mmHgxyear;n = 15,339; 480mmHgxyear ≤ cumSBP < 520mmHgxyear;n = 7214; 520mmHgxyears ≤ cumSBP < 560mmHgxyears;n = 5675; and cumSBP ≥ 560mmHgxyears;n = 10,576). After adjusting for demographic, anthropomorphic, biochemical, socioeconomic and lifestyle parameters and as compared with the first group, the second, third and fourth group showed a significantly higher incidence of diabetes (P-trend < 0.001;hazard ratio (HR);95% confidence interval (CI):1.28(1.08,1.51),1.54(1.29,1.84), and 2.33(1.98,2.73), respectively), higher incidence of impairment of glucose tolerance (P-trend < 0.001;HR;95% CI1.17(1.02,1.33), 1.43(1.25,1.64), and 2.09(1.85,2.37), respectively), and higher incidence of diabetes developing out of an impairment of glucose tolerance (P-trend < 0.001;HR;95% CI:1.22(0.97,1.54),1.47(1.16,1.86), and 2.01(1.62,2.50), respectively). An increase in cumSBP by 10 mmHg/year or an increase in cumDBP by 5 mmHg/year was associated with a hazard ratio of incident diabetes of 1.04 (95% CI:1.03,1.04) and 1.02(1.02,1.03), respectively, with a hazard ratio of incident impairment of glucose tolerance of 1.04(95% CI:1.03,1.04) and 1.03(95% CI:1.02,1.03), respectively, and with a hazard ratio of incident diabetes developing from impairment of glucose tolerance of 1.04(95% CI:1.03,1.04) and 1.03(95% CI:1.02,1.03), respectively. Time-cumulated exposure to elevated blood pressure was significantly associated with an elevated incidence of impaired glucose tolerance and diabetes.

Bai, Litao; Gao, Jialiang; Wei, Fan; Zhao, Jing; Wang, Danwei; Wei, Junping
2018-01-01
Ginseng, one of the oldest traditional Chinese medicinal herbs, has been used widely in China and Asia for thousands of years. Ginsenosides extracted from ginseng, which is derived from the roots and rhizomes of Panax ginseng C. A. Meyer, have been used in China as an adjuvant in the treatment of diabetes mellitus. Owing to the technical complexity of ginsenoside production, the total ginsenosides are generally extracted. Accumulating evidence has shown that ginsenosides exert antidiabetic effects. In vivo and in vitro tests revealed the potential of ginsenoside Rg1, Rg3, Rg5, Rb1, Rb2, Rb3, compound K, Rk1, Re, ginseng total saponins, malonyl ginsenosides, Rd, Rh2, F2, protopanaxadiol (PPD) and protopanaxatriol (PPT)-type saponins to treat diabetes and its complications, including type 1 diabetes mellitus, type 2 diabetes mellitus, diabetic nephropathy, diabetic cognitive dysfunction, type 2 diabetes mellitus with fatty liver disease, diabetic cerebral infarction, diabetic cardiomyopathy, and diabetic erectile dysfunction. Many effects are attributed to ginsenosides, including gluconeogenesis reduction, improvement of insulin resistance, glucose transport, insulinotropic action, islet cell protection, hepatoprotective activity, anti-inflammatory effect, myocardial protection, lipid regulation, improvement of glucose tolerance, antioxidation, improvement of erectile dysfunction, regulation of gut flora metabolism, neuroprotection, anti-angiopathy, anti-neurotoxic effects, immunosuppression, and renoprotection effect. The molecular targets of these effects mainly contains GLUTs, SGLT1, GLP-1, FoxO1, TNF-α, IL-6, caspase-3, bcl-2, MDA, SOD, STAT5-PPAR gamma pathway, PI3K/Akt pathway, AMPK-JNK pathway, NF-κB pathway, and endoplasmic reticulum stress. Rg1, Rg3, Rb1, and compound K demonstrated the most promising therapeutic prospects as potential adjuvant medicines for the treatment of diabetes. This paper highlights the underlying pharmacological mechanisms of the anti-diabetic effects of ginsenosides. PMID:29765322

Diabetes mellitus and depression are the common comorbid disorders affecting humans worldwide. There is an unmet need to develop therapeutic strategies to treat both diabetes mellitus and comorbid depression. The present study evaluated the effectiveness of metformin and ascorbic acid against type 2 diabetes mellitus and comorbid depression in rats. Four groups of diabetic rats were orally administered with vehicle (1mL/kg), metformin (25mg/kg), ascorbic acid (25mg/kg), or combination of metformin (25mg/kg) and ascorbic acid (25mg/kg) for 11 consecutive days. Diabetes was induced by single-dose administration of streptozotocin (65mg/kg, i.p.) with nicotinamide (120mg/kg, i.p.). Comorbid depression was induced by five inescapable foot-shocks (2mA, 2ms duration) at 10s intervals on days 1, 5, 7, and 10. One group of healthy rats received only vehicles to serve as nondiabetic control group. On day 11, animals were sacrificed, and blood and brain samples were collected from each rat following forced swim test. Plasma glucose, insulin, and corticosterone levels were estimated in plasma. The levels of monoamines, proinflammatory cytokines, and oxidative stress were measured in prefrontal cortex. The combination therapy significantly reduced immobility period, glucose, and corticosterone levels relative to diabetes with comorbid depression group. Furthermore, the combination therapy increased the levels of insulin and monoamines, and caused a significant reductions in oxidative stress and proinflammatory cytokines. In conclusion, the present study revealed that metformin and ascorbic acid combination therapy could be a potential strategy to treat type 2 diabetes mellitus and comorbid depression.

Bilirubin concentrations have been recently reported to be negatively associated with type 2 diabetes mellitus. We examined the association between bilirubin concentrations and gestational diabetes mellitus. In a prospective cohort study, 2969 pregnant women were recruited prior to 16 weeks of gestation and were followed up until delivery. The value of bilirubin was tested and oral glucose tolerance test was conducted to screen gestational diabetes mellitus. The relationship between serum bilirubin concentration and gestational weeks was studied by two-piecewise linear regression. A subsample of 1135 participants with serum bilirubin test during 16-18 weeks gestation was conducted to research the association between serum bilirubin levels and risk of gestational diabetes mellitus by logistic regression. Gestational diabetes mellitus developed in 8.5 % of the participants (223 of 2969). Two-piecewise linear regression analyses demonstrated that the levels of bilirubin decreased with gestational week up to the turning point 23 and after that point, levels of bilirubin were increased slightly. In multiple logistic regression analysis, the relative risk of developing gestational diabetes mellitus was lower in the highest tertile of direct bilirubin than that in the lowest tertile (RR 0.60; 95 % CI, 0.35-0.89). The results suggested that women with higher serum direct bilirubin levels during the second trimester of pregnancy have lower risk for development of gestational diabetes mellitus.

2017-09-01
Cardiovascular disease and diabetes mellitus are prominent features of glucose and lipid metabolism disorders. Adiponectin is a key adipokine that is largely involved in glucose and lipid metabolism processes. A growing body of evidence suggests that chronic exposure to inorganic arsenic is associated with cardiovascular disease and diabetes mellitus. We hypothesized that arsenic exposure may increase the risk of cardiovascular disease and diabetes mellitus by affecting the level of adiponectin. In this study, we examined serum adiponectin levels, as well as serum levels of metabolic measures (including fasting blood glucose, insulin, total cholesterol, triglyceride, and high-density lipoprotein (HDL)-cholesterol) in C57BL/6 mice exposed to inorganic arsenic in drinking water (5 and 50 ppm NaAsO 2 ) for 18 weeks. Body mass and adiposity were monitored throughout the study. We found no significant changes in serum insulin and glucose levels in mice treated with arsenic for 18 weeks. However, arsenic exposure decreased serum levels of adiponectin, triglyceride, and HDL-cholesterol. Further, an inverse relationship was observed between urinary concentrations of total arsenic and serum levels of adiponectin. This study suggests that arsenic exposure could disturb the metabolism of lipids and increase the risk of cardiovascular disease by reducing the level of adiponectin.

In 1674 Thomas Willis reported that the presence of urine 'as sweet as honey' was the pathognomonic sign of diabetes mellitus. In the 19th Century several reactions for the detection of glucose in urine were proposed and glucose measurement became common in the laboratories that were being set up in Europe. A case of diabetes mellitus, diagnosed by Namias, the head of the Women's Section of the Medicine Department of Venice Hospital, was reported in 1863 in the 'Giornale Veneto di Scienze Mediche' which contains clinical and laboratory information. A 34-year-old woman was admitted to the hospital for polydypsia, polyuria, bulimia and fatigue. Urine was weighed for 2 months (2-10 kgday(-1)) and the relative density ranged from 1.045 to 1.038. Glucose was measured in the urine using Moore, Trommer and Fehling reagents. A few days after admission a urine sample showed 7.69 parts/100 parts of urine and a blood sample showed 547 mg of glucose/100 g of serum. The assays were carried out in the Clinical Laboratory of Venice Hospital, founded in 1863, directed by Giovanni Bizio, one of the first chemists who graduated at Padua University. In 1863 chemical analyses were commonly carried out in Venice as in the other parts of Habsburg empire.

Exercise intervention might be a promising approach to prevent gestational diabetes mellitus. However, the results remained controversial. We conducted a systematic review and meta-analysis to explore the effect of exercise intervention on gestational diabetes mellitus. PubMed, EMbase, Web of science, EBSCO, and Cochrane library databases were systematically searched. Randomized controlled trials (RCTs) assessing the effect of exercise intervention on gestational diabetes mellitus were included. Two investigators independently searched articles, extracted data, and assessed the quality of included studies. The primary outcome was the incidence of gestational diabetes mellitus, preterm birth, and gestational age at birth. Meta-analysis was performed using random-effect model. Five RCTs involving 1872 patients were included in the meta-analysis. Overall, compared with control intervention, exercise intervention was found to significantly reduce the risk of gestational diabetes mellitus (std. mean difference 0.62; 95% CI 0.43-0.89; P = 0.01), but demonstrated no influence on preterm birth (OR 0.93; 95% CI 0.44-1.99; P = 0.86), gestational age at birth (std. mean difference -0.03; 95% CI -0.12 to 0.07; P = 0.60), glucose 2-h post-OGTT (std. mean difference -1.02; 95% CI -2.75 to 0.71; P = 0.25), birth weight (std. mean difference -0.10; 95% CI -0.25 to 0.04; P = 0.16), Apgar score less than 7 (OR 0.78; 95% CI 0.21-2.91; P = 0.71), and preeclampsia (OR 1.05; 95% CI 0.53-2.07; P = 0.88). Compared to control intervention, exercise intervention was found to significantly reduce the incidence of gestational diabetes mellitus, but had no significant influence on preterm birth, gestational age at birth, glucose 2-h post-OGTT, birth weight, Apgar score less than 7, and preeclampsia.

It is said that black tea is effective against type 2 diabetes mellitus because it can help modulate postprandial hyperglycemia. However, the mechanism underlying its therapeutic and preventive effects on type 2 diabetes mellitus is unclear. In this study, we focused on the effect of black tea on the carbohydrate digestion and absorption process in the gastrointestinal tract. We examined whether black tea can modulate postprandial hyperglycemia. The freeze-dried powder of the aqueous extract of black tea leaves (JAT) was used for in vitro studies of α-amylase activity, α-glucosidase activity, and glucose uptake by glucose transporters in Caco-2 cells; ex vivo studies of small intestinal α-glucosidase activity; and in vivo studies of oral sugar tolerance in GK rats, an animal model of nonobese type 2 diabetes mellitus. Half maximal inhibitory concentration values indicated that JAT significantly reduced α-glucosidase activity, but weakly reduced α-amylase activity. Kinetic studies of rat small intestinal α-glucosidase activity revealed that the combination of JAT and the α-glucosidase inhibitor, acarbose, showed a mixed-type inhibition. JAT had no effect on the uptake of 2'-deoxy-d-glucose by glucose transporter 2 (GLUT2) and the uptake of α-methyl-d-glucose by sodium-dependent glucose transporter 1 (SGLT1). In the oral sucrose tolerance test in GK rats, JAT reduced plasma glucose levels in a dose-dependent manner compared with the control group. The hypoglycemic action of JAT was also confirmed: JAT, in combination with acarbose, produced a synergistic inhibitory effect on plasma glucose levels in vivo. In contrast to the oral sucrose tolerance test, JAT showed no effect in the oral glucose tolerance test. JAT was demonstrated to inhibit the degradation of disaccharides into monosaccharides by α-glucosidase in the small intestine. Thereby indirectly preventing the absorption of the dietary source of glucose mediated by SGLT1 and GLUT2 transporters localized at the apical side of enterocytes in the small intestine. The results indicate that black tea could be useful as a functional food in the dietary therapy for borderline type 2 diabetes mellitus that could modulate postprandial hyperglycemia.

Through a retrospective database analysis, this study seeks to provide an understanding of the utilization of SMBG by insulin therapy and diabetes type and to estimate healthcare costs of blood glucose monitoring in the UK diabetes population. Data were obtained from the IMS LifeLink Electronic Medical Record-Europe (EMR-EU) Database, a longitudinal database containing anonymized patient records from physician-practice data systems of office-based physicians in the UK. Depending on the insulin types used for type 1 and type 2 diabetes, patients were sub-categorized into one of four insulin regimen groups (basal, bolus, pre-mixed, or basal-bolus). Frequency of blood glucose testing was assessed descriptively throughout the 12-month post-index period, and generalized linear models were used to evaluate the effect of baseline characteristics, including insulin type, on the likelihood of blood glucose test utilization. Healthcare resource utilization and costs for all-cause services were assessed by insulin type. This study identified 8322 type 1 and type 2 diabetes patients with two insulin pharmacy records between January 1, 2009 and December 31, 2010. After applying study inclusion and exclusion criteria, a total of 2676 (32.2%) insulin-treated diabetes mellitus patients in the UK were identified, with the number of pharmacy blood glucose test strips averaging 771.1 (median 600). The glucose testing frequency was lowest among basal-only insulin patients and pre-mixed insulin patients (mean=576.2 [median=450] and mean=599.5 [median=500], respectively; non-significantly different) compared to other insulin types. Although the data did not capture the glucose frequency comprehensively, it varied significantly by insulin types, and was higher than what is recommended in the guidelines for patients with type 2 diabetes.

Folk medicine stories accredited the aptitude of camel milk (CMK) as a hypoglycemic agent and recent studies have confirmed this in the diabetic patients and experimental animals. However, the mechanism(s) by which CMK influences glucose homeostasis is yet unclear. The current study investigated the changes in the glucose homeostatic parameters, the incretin hormones, and the inflammatory cytokines in the CMK-treated diabetic animals. A model of type 2 diabetes mellitus was induced in rats by intraperitoneal injection of streptozotocin 40 mg/kg/day for 4 repeated doses. Camel milk treatment was administered for 8 weeks. The changes in glucagon like peptide-1 (GLP-1), glucose dependent insulinotropic peptide (GIP), glucose tolerance, fasting and glucose-stimulated insulin secretion, insulin resistance (IR), TNF-α, TGF-β1, lipid profile, atherogenic index (AI), and body weight were investigated. The untreated diabetic animals showed hyperglycemia, increased HOMA-IR, hyperlipidemia, elevated AI, high serum incretins [GLP-1 and GIP], TNF-α, and TGF-β1 levels and weight loss as compared with the control group. Camel milk treatment to the diabetic animals resulted in significant lowered fasting glucose level, hypolipidemia, decreased HOMA-IR, recovery of insulin secretion, weight gain, and no mortality during the study. Additionally, CMK inhibits the diabetes-induced elevation in incretin hormones, TNF-α and TGF-β1 levels. The increase in glucose-stimulated insulin secretion, decreased HOMA-IR, modulation of the secretion and/or the action of incretins, and the anti-inflammatory effect are anticipated mechanisms to the antidiabetic effect of CMK and suggest it as a valuable adjuvant antidiabetic therapy. © Georg Thieme Verlag KG Stuttgart · New York.

Insulin is currently the drug of choice in treating patients with gestational diabetes mellitus but insulin is expensive, inconvenient to store and use and probably associated with more risks of asymptomatic hypoglycemia in comparison with some oral agents. This randomized clinical trial was conducted to evaluate the efficacy and safety of glyburide in patients with gestational diabetes mellitus in comparison with insulin therapy. Pregnant women aged between 18-45 years with singleton pregnancies and in their 24-36 weeks of gestation were assessed for eligibility. Women with gestational diabetes mellitus were randomly allocated to two insulin and glyburide groups and compared with maternal and neonatal outcome. Ninety-six women with gestational diabetes mellitus enrolled in the study. At screen and treated fasting and post-prandial blood glucose levels were similar in both groups. Time for beginning the treatment to control the glycemic index was 28.30 (±20.60) days in the insulin group and 22.56 (±18.86) in the glyburide group. There was no statistically significant difference in time-to-control the blood glucose level in two studied group. Time, between beginning the treatment of GDM and delivery, was 53.22 (±28.96) days in the insulin group and 56.67 (±30.47) in the glyburide group. There was no statistically significant difference between the times of treatment-to-delivery in two studied groups. There were no statistically significant differences between maternal and neonatal outcomes in two studied groups. Glyburide can effectively and safely control the glycemic index in women with gestational diabetes mellitus in comparison with insulin.

Oxidative stress, insulin resistance, dyslipidemia and type 2 diabetes mellitus
Tangvarasittichai, Surapon
2015-01-01
Oxidative stress is increased in metabolic syndrome and type 2 diabetes mellitus (T2DM) and this appears to underlie the development of cardiovascular disease, T2DM and diabetic complications. Increased oxidative stress appears to be a deleterious factor leading to insulin resistance, dyslipidemia, β-cell dysfunction, impaired glucose tolerance and ultimately leading to T2DM. Chronic oxidative stress, hyperglycemia and dyslipidemia are particularly dangerous for β-cells from lowest levels of antioxidant, have high oxidative energy requirements, decrease the gene expression of key β-cell genes and induce cell death. If β-cell functioning is impaired, it results in an under production of insulin, impairs glucose stimulated insulin secretion, fasting hyperglycemia and eventually the development of T2DM.

Rosiglitazone, a thiazolidinedion antidiabetic agent, improves insulin resistance in patients with type 2 diabetes mellitus. Rosiglitazone binds to PPAR-gamma with high affinity and the in vivo antidiabetic potency of rosiglitazone is correlated with its high biding affinity. In animal models of insulin resistence, rosiglitazone decreased plasma glucose, triglyceride and insulin levels and also prevented diabetic nephropathy and pancreatic islet cell degeneration. In clinical trials in patients with type 2 diabetes mellitus, rosiglitazone, 2 to 12 mg/day (as a single daily dose or 2 divided daily doses), improved glycemic control as demonstrated, by decreases in fasting plasma glucose and HbA1C levels. Rosiglitazone did not appear to increase the risk of hypoglycemia and there was no evidence of hepatotoxicity in pre-clinical trials.

OBJECTIVE The aim of this study is to establish a causal relationship between excess body weight and the onset of diabetes in a retrospective cohort study. METHODS This 10-year observational cohort study investigated 969 men and 585 women (23 to 80 years of age), who underwent voluntary complete medical check-ups and an annual 75-g oral glucose tolerance test (75g-OGTT). Participants with fasting plasma glucose ≥ 126 mg/dl, 2-h glucose level in a 75g-OGTT ≥ 200 mg/dl and/or received medical treatment for type 2 diabetes during the previous year were counted as new-onset diabetics. We assessed the independent contribution of increased BMI to the risk of developing type 2 diabetes with Cox proportional hazard model. RESULT During the follow-up period, we diagnosed 86 men and 49 women with new-onset type 2 diabetes. In the Cox proportional hazards model, the risk of diabetes mellitus increased with increasing BMI, even after adjusting for age, sex, blood pressure, metabolic profiles, and insulin resistance. In the final model, setting BMI less than 25 as a reference group, the Hazard ratios for diabetes mellitus was 3.12 for those with a BMI of 25–27.4 and increased to 3.80 for participants with a BMI of 27.5 or higher. CONCLUSION Overweight/obesity (high BMI) is an independent and dose-dependent risk factor for type 2 diabetes in overweight Japanese patients. Our results confirmed the usefulness of BMI as a classic parameter, and the importance of lifestyle modification and better management among people with overweight/obesity for prevention of type 2 diabetes mellitus PMID:22821094

Metabolic disorders in vertigo, tinnitus, and hearing loss.
Kaźmierczak, H; Doroszewska, G
2001-01-01
Vertigo, tinnitus, and hearing loss are common complaints among populations of industrial countries, especially in persons older than 40 years. Numerous agents are known to incite vertigo, tinnitus, and hearing loss, among them hyperinsulinemia, diabetes mellitus, and hyperlipidemia. In this study, we proposed to assess the occurrence of hyperinsulinemia, diabetes mellitus, and hyperlipidemia in patients suffering from vertigo, tinnitus, or hearing loss of unknown origin. Results of various tests in 48 patients were compared to those in 31 control subjects. Assessments of body mass index, blood pressure, and laryngological, audiometric, and electronystagmographic parameters were performed in all study participants. An oral glucose tolerance test was used to evaluate insulin levels, and lipoprotein phenotyping served to determine cholesterol, triglyceride, and lipoprotein levels. Patients were found to be significantly more overweight (on the basis of body mass index) than were the control subjects. Hypertension was more common among patients than controls, but the difference was significant only between the men in the two groups. Disturbances of glucose metabolism were found in 27.1% of patients but in only 9.7% of controls. Diabetes mellitus was not present in any controls but was identified in four patients. Hyperinsulinemia was almost twice as common in patients as in controls. Only the occurrence of hyperlipoproteinemia seemed not to differ between patients and control subjects. We conclude that such disturbances of glucose metabolism as diabetes mellitus and hyperinsulinemia may be responsible for inner ear diseases, whereas the role of disturbances of lipid metabolism remains vague.

To evaluate the effects of diets differing in type and quantity of fiber on glycemic control in dogs with naturally occurring insulin-dependent diabetes mellitus. Prospective randomized crossover controlled trial. 7 dogs with well-regulated naturally occurring insulin-dependent diabetes mellitus. Dogs were fed 1 of 3 diets for 1 month each in 1 of 6 randomized diet sequences. Diets included a low-fiber diet (LF) and 2 high-fiber diets; 1 contained only insoluble fiber (HIF), and 1 contained soluble fiber in addition to insoluble fiber (HSF). Caloric intake was unchanged throughout the study. Glycemic control was assessed after each feeding trial by measuring serum fructosamine concentration and performing 5 serial measurements of blood glucose concentration every 2 hours after the morning feeding and insulin injection. Significant differences were not detected in body weight, required insulin dosage, or albumin concentration among dogs fed the HIF, HSF, and LF diets. Mean and maximum blood glucose concentrations and area under the blood glucose curve were significantly lower in dogs fed the HIF diet, compared with values in the same dogs fed the HSF or LF diet. Fructosamine concentration was significantly lower in dogs fed the HIF or HSF diet, compared with values in the same dogs fed the LF diet. In dogs with naturally occurring insulin-dependent diabetes mellitus, a dry, high insoluble-fiber diet may aid in glycemic control.

To present recommendations for the certified athletic trainer in the management of type 1 diabetes in the athlete. In managing diabetes, the most important goal is to keep blood glucose levels at or as close to normal levels as possible without causing hypoglycemia. This goal requires the maintenance of a delicate balance among hypoglycemia, euglycemia, and hyperglycemia, which is often more challenging in the athlete due to the demands of physical activity and competition. However, effectively managing blood glucose, lipid, and blood pressure levels is necessary to ensuring the long-term health and well-being of the athlete with diabetes. These recommendations are intended to provide the certified athletic trainer participating in the management of an athlete with type 1 diabetes mellitus with the specific knowledge and problem-solving skills needed. Athletic trainers have more contact with the athlete with diabetes than most members of the diabetes management team do and so must be prepared to assist the athlete as required.

To determine the prevalence of both prediabetes and type 2 diabetes mellitus (T2DM) by postpartum oral glucose tolerance test (ppOGTT) in Italian women diagnosed with gestational diabetes mellitus (GDM), and identify antepartum predictors of glucose intolerance. Retrospective study of 454 Caucasian women that underwent a 75g OGTT between 6 and 12 weeks postpartum in Calabria (Southern Italy) between 2004 and 2012. Prediabetes and T2DM were diagnosed according to the American Diabetes Association (ADA) criteria. Data were examined by univariate analysis and multiple regression analysis. 290 women (63.9%) were normal, 146 (32.1%) had prediabetes (85 impaired fasting glycemia; 61 impaired glucose tolerance), and 18 (4.0%) had T2DM. Of the continuous variables, pre-pregnancy body mass index (BMI), age at pregnancy, fasting plasma glucose (FPG) at gravid OGTT, and week at diagnosis of GDM were associated with prediabetes and T2DM, whereas the parity was associated with T2DM only. For categorical traits, pre-pregnancy BMI ≥ 25 and previous diagnosis of polycystic ovary syndrome (PCOS) emerged as the strongest predictors of prediabetes whereas the strongest predictors of T2DM were FPG ≥ 100 mg/dl (5.6 mmol/l) at GDM diagnosis and pre-pregnancy BMI ≥ 25. Moreover, FPG at GDM screening was a good predictor of T2DM after receiver-operating-characteristic analysis. Our findings confirm the high prevalence of glucose intolerance in the early postpartum period in women with previous GDM. PCOS emerges as a new strong antepartum predictor of prediabetes.

The role of salt restriction in patients with impaired glucose tolerance and diabetes mellitus is controversial, with a lack of well controlled, longer term, modest salt reduction trials in this group of patients, in spite of the marked increase in cardiovascular risk. We carried out a 12-week randomized double-blind, crossover trial of salt restriction with salt or placebo tablets, each for 6 weeks, in 46 individuals with diet-controlled type 2 diabetes mellitus or impaired glucose tolerance and untreated normal or high normal blood pressure (BP). From salt to placebo, 24-hour urinary sodium was reduced by 49±9 mmol (2.9 g salt). This reduction in salt intake led to fall in clinic BP from 136/81±2/1 mm Hg to 131/80±2/1 mm Hg, (systolic BP; P<0.01). Mean ambulatory 24-hour BP was reduced by 3/2±1/1 mm Hg (systolic BP, P<0.01 and diastolic BP, P<0.05), and albumin/creatinine ratio was reduced from 0.73 mg/mmol (0.5-1.5) to 0.64 mg/mmol (0.3-1.1; P<0.05). There was no significant change in fasting glucose, hemoglobin A1c, or insulin sensitivity. These results demonstrate that a modest reduction in salt intake, to approximately the amount recommended in public health guidelines, leads to significant and clinically relevant falls in BP in individuals who are early on in the progression of diabetes mellitus with normal or mildly raised BP. The reduction in urinary albumin excretion may carry additional benefits in reducing cardiovascular disease above the effects on BP. © 2016 American Heart Association, Inc.

Type 2 diabetes mellitus and hypertension overlap in the population. In many subjects, development of diabetes mellitus is characterized by a relatively rapid increase in plasma glucose values. Whether a similar phenomenon occurs during the development of hypertension is not known. We analyzed the pattern of blood pressure (BP) changes during the development of hypertension in patients with or without diabetes mellitus using data from the MCDS (Mexico City Diabetes Study; a population-based study of diabetes mellitus in Hispanic whites) and in the FOS (Framingham Offspring Study, a community-based study in non-Hispanic whites) during a 7-year follow-up. Diabetes mellitus at baseline was a significant predictor of incident hypertension (in FOS, odds ratio, 3.14; 95% confidence interval, 2.17-4.54) independently of sex, age, body mass index, and familial diabetes mellitus. Conversely, hypertension at baseline was an independent predictor of incident diabetes mellitus (in FOS, odds ratio, 3.33; 95% CI, 2.50-4.44). In >60% of the converters, progression from normotension to hypertension was characterized by a steep increase in BP values, averaging 20 mm Hg for systolic BP within 3.5 years (in MCDS). In comparison with the nonconverters group, hypertension and diabetes mellitus converters shared a metabolic syndrome phenotype (hyperinsulinemia, higher body mass index, waist girth, BP, heart rate and pulse pressure, and dyslipidemia). Overall, results were similar in the 2 ethnic groups. We conclude that (1) development of hypertension and diabetes mellitus track each other over time, (2) transition from normotension to hypertension is characterized by a sharp increase in BP values, and (3) insulin resistance is one common feature of both prediabetes and prehypertension and an antecedent of progression to 2 respective disease states. © 2018 American Heart Association, Inc.

Previous studies of Citrus spp. peel have shown hypoglycemic and antioxidant activities. Citrus limetta has been studied for its therapeutic properties. Diabetes mellitus (DM) is a health problem in Mexico and worldwide, that takes a vital importance due to its high incidence. Recently, scientists have searched natural sources to control the disease. In this study, we evaluated the in vitro hypoglycemic activity and in vivo postprandial glycemic effect of C. limetta peel flour by glucose adsorption and retardation assays as well as postprandial serum glucose levels using a group of female Balb-c mice, respectively. C. limetta peel flour showed a glucose adsorption capacity of 16.58 mM, having a similar effect regarding the positive control. The glucose diffusion in the dialysate was elevated, with a glucose dialysis retardation index of 33.79% in a period of 3 h, showing similar results to positive control. Postprandial serum glucose levels in the animal group treated with C. limetta peel flour showed a glucose level of 41.4 mg/dL, being this value significantly lower than negative control group and similar to positive control. Toxicity tests showed good tolerance to the dose of 2000 mg/kg. C. limetta peel flour could act as a source of functional compounds for the control of DM. Citrus limetta peel flour showed a glucose adsorption capacity similar to the positive controlThe glucose diffusion in the dialysate was elevated, showing similar results to positive controlPostprandial serum glucose levels in the animal group treated with C. limetta peel flour showed a glucose level significantly lower than negative control group and similar to positive controlToxicity tests showed good tolerance C. limetta peel flour could act as a source of functional compounds for the control of diabetes mellitus.

This study evaluated the impact of patient education on adherence to a diabetes care plan (e.g., anthropometric, lipidemic, and glycemic parameters) among adults with type II diabetes mellitus without adequate glycemic control. A total of 61 ambulatory adults with type II diabetes mellitus (mean age: 53.6 ± 8.2 years, 70.5% female) were evaluated for anthropometrics, duration of diabetes mellitus, type of anti-diabetic treatment, blood biochemistry, and glycemic parameters in this 3-month prospective observational single-center study. During the course of the study, participants demonstrated a significant decrease in body weight and fat percentage and HbA1c (p < .001 for each). None of the factors evaluated was a significant determinant for glycemic parameters. These findings revealed that adults with type II diabetes mellitus who received education on adherence to routine self-monitoring of blood glucose, standard diabetic diet, and an exercise program delivered by certified diabetes educators had better glycemic control and significant decrease in body weight and fat percentage over a 3-month monitoring period.

Type 2 diabetes mellitus is characterized by shorter leukocyte telomere length, but the relationship between leukocyte telomere length and type 2 diabetes mellitus development is rather questioned. Fasting and post-load glycaemia associated with different types of insulin resistance and their relation with leukocyte telomere length remains unknown. We compared leukocyte telomere length and fasting or post-load glucose levels in persons who do not receive glucose lowering treatment. For 82 randomly selected rural residents of Ukraine, aged 45+, not previously diagnosed with type 2 diabetes mellitus, the WHO oral glucose tolerance test and anthropometric measurements were performed. Leukocyte telomere length was measured by standardized method of quantitative monochrome multiplex polymerase chain reaction in real time. Spearman's or Pearson's rank correlation was used for correlation analysis between fasting plasma glucose or 2-h post-load plasma glucose levels and leukocyte telomere length. Logistical regression models were used to evaluate risks of finding short or long telomeres associated with fasting plasma glucose or 2-h post-load plasma glucose levels. No association of fasting plasma glucose and leukocyte telomere length was revealed, whereas 2-h post-load plasma glucose levels demonstrated a negative correlation ( P < 0.01) with leukocyte telomere length. Waist circumference and systolic blood pressure were negatively related ( P = 0.03) with leukocyte telomere length in men. Oral glucose tolerance test result-based glycemic categories did not show differences between mean leukocyte telomere length in categories of normal fasting plasma glucose and 2-h post-load plasma glucose (NGT, n = 33); diabetes mellitus (DM), n = 18 and impaired fasting glucose/tolerance (IFG/IGT, n = 31) levels. A correlation relationship between leukocyte telomere length and 2-h post-load plasma glucose level in NGT; IFG/IGT and DM groups ( P = 0.027; 0.029 and 0.049, respectively) was revealed; the association between leukocyte telomere length and fasting plasma glucose was confirmed in DM group only ( P = 0.009). Increase of 2-h post-load plasma glucose (but not fasting plasma glucose) level improves the chances of revealing short telomeres: OR 1.52 (95% CI 1.04-2.22), P = 0.03. After the adjustment for age, gender, waist circumference, systolic blood pressure, and fasting plasma glucose, these phenomena remain significant. We conclude that 2-h post-load plasma glucose but not fasting plasma glucose is inversely associated with leukocyte telomere length. Impact statement • Contradictory epidemiologic data have been obtained about the link between the leucocyte telomere length (LTL) and diabetes. Type 2 diabetes (T2D) is likely to be pathophysiologically heterogeneous, but comparison of the association of LTL separately with fasting plasma glucose (FPG) and 2-h post-load plasma glucose (2hPG) levels has not been done before. Thus, the study of LTL changes associated with different types of hyperglycaemia, that largely determine the heterogenity of T2D is important. • In a population-based study of rural Ukrainians, we were the first to demonstrate that the increase of 2hPG (but not FPG) level increases the chances of revealing short telomeres. • The obtained data can help to clarify the relationship between the LTL shortening and different conditions of the insulin resistance (mainly liver resistance in high FPG and mostly muscle and adipose tissue resistance in high 2hPG).

Treatment of type 2 diabetes mellitus by viral eradication in chronic hepatitis C: Myth or reality?
Vanni, Ester; Bugianesi, Elisabetta; Saracco, Giorgio
2016-02-01
Chronic hepatitis C is a systemic disease inducing metabolic alterations leading to extrahepatic consequences. In particular, hepatitis C virus (HCV) infection seems to increase the risk of incident type 2 diabetes mellitus in predisposed individuals, independently of liver disease stage. The mechanisms through which hepatitis C induces T2DM involve direct viral effects, insulin resistance, pro-inflammatory cytokines and other immune-mediated processes. Many studies have reported the clinical consequences of type 2 diabetes mellitus on hepatitis C outcome, but very few studies have addressed the issue of microangiopathic complications among patients with hepatitis C only, who develop type 2 diabetes mellitus. Moreover, clinical trials in HCV-positive patients have reported improvement in glucose metabolism after antiviral treatment; recent studies have suggested that this metabolic amelioration might have a clinical impact on type 2 diabetes mellitus-related complications. These observations raise the question as to whether the HCV eradication may also have an impact on the future morbidity and mortality due to type 2 diabetes mellitus. The scope of this review is to summarise the current evidence linking successful antiviral treatment and the prevention of type 2 diabetes mellitus and its complications in hepatitis C-infected patients.

A previous genome-wide association study showed that a genetic variant of sortilin was associated with the risk of coronary artery disease (CAD). However, the role of circulating sortilin is still unknown. We investigated the potential role of plasma sortilin as a biomarker for CAD and diabetes mellitus. We enrolled statin-naïve subjects with CAD (n = 31) who underwent coronary artery bypass surgery and control subjects (n = 116) who were free from CAD as evaluated by coronary CT angiography. The presence of diabetes mellitus was evaluated and plasma sortilin levels were measured with a commercial ELISA kit. Plasma sortilin levels were higher in subjects with CAD and subjects with diabetes mellitus than in those without CAD or diabetes mellitus. Subjects in the highest sortilin tertile group were older and had higher glucose and HbA1c levels, but lipid profiles in the three tertile groups were comparable. Multivariable logistic regression analysis revealed that sortilin levels were independently associated with CAD. In addition, the receiver operating characteristic curve analysis showed that plasma sortilin levels could identify the presence of CAD or diabetes mellitus. Elevated circulating sortilin levels are associated with CAD and diabetes mellitus and can be used as a biomarker of both diseases in statin-naïve subjects.

Exercise-related hypoglycemia in diabetes mellitus
Younk, Lisa M; Mikeladze, Maia; Tate, Donna; Davis, Stephen N
2011-01-01
Current recommendations are that people with Type 1 and Type 2 diabetes mellitus exercise regularly. However, in cases in which insulin or insulin secretagogues are used to manage diabetes, patients have an increased risk of developing hypoglycemia, which is amplified during and after exercise. Repeated episodes of hypoglycemia blunt autonomic nervous system, neuroendocrine and metabolic defenses (counter-regulatory responses) against subsequent episodes of falling blood glucose levels during exercise. Likewise, antecedent exercise blunts counter-regulatory responses to subsequent hypoglycemia. This can lead to a vicious cycle, by which each episode of either exercise or hypoglycemia further blunts counter-regulatory responses. Although contemporary insulin therapies cannot fully mimic physiologic changes in insulin secretion, people with diabetes have several management options to avoid hypoglycemia during and after exercise, including regularly monitoring blood glucose, reducing basal and/or bolus insulin, and consuming supplemental carbohydrates.

To develop and validate a simplified screening test for undiagnosed Type 2 diabetes mellitus and impaired fasting glucose for the Slovenian population (SloRisk) to be used in the general population. Data on 11 391 people were collected from the electronic health records of comprehensive medical examinations in five Slovenian healthcare centres. Fasting plasma glucose as well as information related to the Finnish Diabetes Risk Score questionnaire, FINDRISC, were collected for 2073 people to build predictive models. Bootstrapping-based evaluation was used to estimate the area under the receiver-operating characteristic curve performance metric of two proposed logistic regression models as well as the Finnish Diabetes Risk Score model both at recommended and at alternative cut-off values. The final model contained five questions for undiagnosed Type 2 diabetes prediction and achieved an area under the receiver-operating characteristic curve of 0.851 (95% CI 0.850-0.853). The impaired fasting glucose prediction model included six questions and achieved an area under the receiver-operating characteristic curve of 0.840 (95% CI 0.839-0.840). There were four questions that were included in both models (age, sex, waist circumference and blood sugar history), with physical activity selected only for undiagnosed Type 2 diabetes and questions on family history and hypertension drug use selected only for the impaired fasting glucose prediction model. This study proposes two simplified models based on FINDRISC questions for screening of undiagnosed Type 2 diabetes and impaired fasting glucose in the Slovenian population. A significant improvement in performance was achieved compared with the original FINDRISC questionnaire. Both models include waist circumference instead of BMI. © 2018 Diabetes UK.

2018-01-01
As the first cardiovascular (CV) outcome trial of a glucose-lowering agent to demonstrate a reduction in the risk of CV events in patients with type 2 diabetes mellitus (T2DM), the EMPAgliflozin Removal of Excess Glucose: Cardiovascular OUTCOME Event Trial in Type 2 Diabetes Mellitus Patients (EMPA-REG OUTCOME®) trial, which investigated the sodium glucose cotransporter 2 (SGLT2) inhibitor empagliflozin, has generated great interest among health care professionals. CV outcomes data for another SGLT2 inhibitor, canagliflozin, have been published recently in the CANagliflozin CardioVascular Assessment Study (CANVAS) Program, as have CV data from the retrospective real-world study Comparative Effectiveness of Cardiovascular Outcomes in New Users of Sodium-Glucose Cotransporter-2 Inhibitors (CVD-REAL), which compared SGLT2 inhibitors with other classes of glucose-lowering drugs. This review discusses the results of these three studies and, with a focus on EMPA-REG OUTCOME, examines the possible mechanisms by which SGLT2 inhibitors may reduce CV risk in patients with T2DM.

Adipocytokines and insulin resistance across various degrees of glucose tolerance in pregnancy.
Skvarca, A; Tomazic, M; Krhin, B; Blagus, R; Janez, A

Gestational diabetes mellitus is characterized by progressive insulin resistance. Adipocytokines are thought to be associated with insulin resistance. This cross-sectional study evaluated the associations between serum concentrations of several adipocytokines and insulin resistance at different stages of glucose tolerance in pregnancy, using the homeostasis model assessment of insulin resistance (HOMA-IR) as a reference. According to oral glucose tolerance test results, 74 pregnant women were divided into three groups: normal glucose tolerance (n = 25); intermediate glucose tolerance (n = 19); gestational diabetes mellitus (n = 30). Adiponectin, leptin, resistin, visfatin and retinol-binding protein 4 (RBP4) concentrations were measured using enzyme-linked immuno sorbent assays. Groups were comparable regarding age, week of gestation and body mass index before gestation. There were statistically significant between-group differences in HOMA-IR, but no significant differences regarding serum adipocytokine concentrations. Adipo nectin, leptin, resistin, visfatin and RBP4 were not associated with the degree of glucose tolerance in pregnancy. Concentrations of these adipocytokines are not sufficiently sensitive to replace HOMA- IR in pregnancy.

The Infant Born to a Woman with Gestational Diabetes.
Povinelli, Theresa; Lim, Caitlin; Raines, Deborah A
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 mellitus (GDM) is associated with life-long increased risk of type 2 diabetes: affected women are advised to undergo oral glucose tolerance testing (OGTT) at 6-12 weeks postpartum, then glucose screening every 1-3 years. We investigated whether in women with GDM, antenatal clinical factors predicted postpartum abnormal glucose tolerance and compliance with screening. In women with GDM delivering 2007 to mid-2009 in a single hospital, antenatal/obstetric data and glucose tests at 6-12 weeks postpartum and during 5.5 years post-pregnancy were retrospectively collected. Predictors of return for testing and abnormal glucose tolerance were identified using multivariate analysis. Of 165 women, 117 (70.9%) returned for 6-12 week postpartum OGTT: 23 (19.6%) were abnormal. Smoking and parity, independent of socioeconomic status, were associated with non-return for testing. Fasting glucose ≥5.4 mmol/L on pregnancy OGTT predicted both non-return for testing and abnormal OGTT. During 5.5 years post-pregnancy, 148 (89.7%) women accessed glucose screening: nine (6.1%) developed diabetes, 33 (22.3%) had impaired fasting glucose / impaired glucose tolerance. Predictors of abnormal glucose tolerance were fasting glucose ≥5.4 mmol/L and 2-h glucose ≥9.3 mmol/L on pregnancy OGTT (~2.5-fold increased risk), and polycystic ovary syndrome (~3.4 fold increased risk). Risk score calculation, based on combined antenatal factors, did not improve predictions. Antenatal clinical factors were modestly predictive of return for testing and abnormal glucose tolerance post-pregnancy in women with GDM. Risk score calculations were ineffective in predicting outcomes: risk scores developed in other populations require validation. Ongoing glucose screening is indicated for all women with GDM. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

A large neck circumference might be an indicator of metabolic syndrome and its components, and for certain patients is more practical as an index than waist circumference. The demarcation value for neck circumference that suggests metabolic syndrome appears to vary by ethnic group. Gestational diabetes mellitus is considered a component of metabolic syndrome in pregnant women. We investigated whether neck circumference in Han Chinese women is associated with gestational diabetes mellitus in early pregnancy, and determined a predictive demarcation value. A nested case-control study was carried out with 255 women aged 18-35 years. Gestational diabetes mellitus was diagnosed according to the criteria of the American Diabetes Association through a 2-h, 75-g oral glucose tolerance test. Of the total population, 41 (16%) women developed gestational diabetes mellitus by 24-28 weeks of gestation. Neck circumference at gestational week 16 positively correlated with pre-pregnancy waist circumference, bodyweight and body mass index, and maternal age (P = 0.029) and hemoglobin A1c at gestational week 24 (P ≤ 0.001). By binary logistic regression, neck circumference was an independent predictor of gestational diabetes mellitus (odds ratio 1.840, 95% confidence interval 1.040-3.254; P = 0.036). According to the receiver operating characteristic curve, for predicting gestational diabetes mellitus the optimal demarcation for neck circumference at gestational week 16 was 35.15 cm. Neck circumference is a viable tool to screen for gestational diabetes mellitus. In this population of pregnant Han Chinese women, a neck circumference of ≥35.15 cm was a predictor of gestational diabetes mellitus. © 2016 The Authors.

Diabetes mellitus is a group of diseases characterized by chronic hyperglycemia. Women who develops hyperglycemia for the first time during pregnancy receive the diagnosis gestational diabetes mellitus (GDM). Presently, there is no consensus about the diagnostic criteria for GDM. A majority of these women subsequently develop postpartum overt diabetes making it important to identify these patients as early as possible. In this study we investigated if plasma levels of the interleukin-1 receptor antagonist (IL-1Ra), an endogenous inhibitor of IL-1 signaling, can be used as a complementary biomarker for diagnosing GDM and predicting postpartum development of overt diabetes mellitus. Patients participating in this study (n = 227) were diagnosed with their first GDM 2004-2013 at Lund University Hospital, Lund, Sweden. Healthy pregnant volunteers (n = 156) were recruited from women's welfare centers in the same region 2014-2015. Levels of IL-1Ra and C-peptide were analyzed in ethylenediaminetetraacetic acid (EDTA)-plasma or serum using enzyme linked immunosorbent assay (ELISA). GDM patients had significantly lower levels of IL-1Ra than the control group (p = 0.012). In addition, GDM patients that had developed impaired glucose tolerance (IGT) or type 2 diabetes mellitus postpartum had significantly lower levels of IL-1Ra, and significantly higher levels of C-peptide than GDM patients that had not developed diabetes mellitus postpartum (p = 0.023) and (p = 0.0011) respectively. An inverse correlation was found between IL-1Ra and serum C-peptide levels in the control group (rs = -0.31 p = 0.0001). Our results show that IL-1Ra might be included in a future panel of biomarkers, both for diagnosing GDM to complement blood glucose, and also identifying GDM patients that are at risk of developing type 2 diabetes mellitus postpartum. However, the ROC curve analysis provided a sensitivity of 52.2% and specificity of 67.1%, which nonetheless may not be sufficient enough to use IL-1Ra as a sole biomarker.

The aim of the present research was to study the ghrelin level, executive function and their possible association in patients with type 2 diabetes mellitus. A total of 370 people were recruited between March 2015 and March 2016 in this study. Among them, 212 participants were patients with type 2 diabetes mellitus and 158 participants were included as the control group. Their blood sample was analyzed for the level of ghrelin and other clinical indexes. Cognitive function was measured by the Montreal Cognitive Assessment, and executive function was evaluated by the Wisconsin Card Sorting Test. In the type 2 diabetes mellitus group, age, years of education, duration of diabetes, fasting blood glucose, glycated hemoglobin, hypertension and waist-to-hip ratio were correlated with total Montreal Cognitive Assessment scores. No association was found between ghrelin level and total Montreal Cognitive Assessment score in patients with type 2 diabetes mellitus. However, ghrelin was found to be a significant predictor for executive function impairment measured by the Wisconsin Card Sorting Test in patients with type 2 diabetes mellitus. The level of serum ghrelin might be a biomarker of executive function and become a strong predictor of executive function impairment in patients with type 2 diabetes mellitus. Ghrelin might have a potential protective effect against cognitive function impairment in type 2 diabetes patients. © 2016 The Authors.

OBJECTIVES—To determine if the recovery of nerve function after ischaemic block is impaired in patients with diabetes mellitus relative to healthy controls. METHODS—Median nerve impulse conduction and vibratory thresholds in the same innervation territory were studied in patients with diabetes mellitus (n = 16) and age matched controls (n = 10) during and after 30 minutes of cuffing of the forearm. RESULTS—Cuffing caused a 50% reduction of the compound nerve action potential (CNAP) after 21.9 (SEM 1.6) minutes in patients with diabetes mellitus and after 10.6 (0.7) minutes in controls. After release of the cuff the half life for CNAP recovery was 5.13 (0.45) minutes in patients with diabetes mellitus and <1 minute in controls. At seven minutes after release of the cuff CNAP was fully restored in the controls whereas in patients with diabetes mellitus CNAP had only reached 75.1 (4.1)% of its original amplitude. After onset of ischaemia it took 14.6 (1.9) minutes in patients with diabetes mellitus before the vibratory threshold was doubled, whereas this took 5.8 (0.8) minutes in controls. After release of the cuff half time for recovery of vibratory threshold was 8.8 (1.0) minutes in patients with diabetes mellitus and 2.6 (0.3) minutes in controls. Ten minutes after the cuff was released the threshold was still raised (2.0 (0.3)-fold) in the diabetes mellitus group, whereas it was normalised in controls. Among patients with diabetes mellitus the impaired recovery correlated with older age, higher HbA1c, and signs of neuropathy, but not with blood glucose. CONCLUSION—After ischaemia there is a delayed recovery of nerve conduction and the vibratory sensibility in patients with diabetes mellitus. Impaired recovery after ischaemic insults may contribute to the high frequency of entrapment neuropathy in patients with diabetes mellitus. PMID:9328252

This work aimed to study the effect of swimming exercise on serum vitamin D level and tissue vitamin D receptors in experimentally induced type 2 Diabetes Mellitus. Sixty adult male rats were divided into control and diabetic groups. Each was further subdivided into sedentary and exercised subgroups. Diabetes Mellitus was induced by a single intraperitoneal dose of streptozotocin (50 mg/kg) dissolved in cold 0.01 M citrate buffer (pH 4.5). The exercised subgroups underwent swimming for 60 min, 5 times a week for 4 weeks. Serum glucose, insulin, homeostasis model assessment of insulin resistance (HOMA-IR), lipids, vitamin D and tissue Vitamin D receptors (VDR) were evaluated. Significant increase in serum glucose, insulin, HOMA-IR, cholesterol, triglycerides, and low density lipoprotein (LDL) levels in sedentary diabetic rats was detected. On the other hand, high density lipoprotein (HDL), free fatty acids, serum vitamin D and pancreatic, adipose, and muscular VDR showed a significant decrease in the same group. It is evident that all these parameters were reversed by swimming exercise indicating its beneficial role in type 2 Diabetes. In diabetic groups; serum vitamin D was found to be correlated negatively with serum glucose, insulin, HOMA, cholesterol, triglycerides, and LDL and positively correlated with HDL and tissue VDR. In conclusion, Disturbed vitamin D is associated with metabolic impairments in sedentary diabetic rats. Moderate swimming exercise is beneficial in improving these consequences through modulation of vitamin D status. Future studies could be designed to investigate the effect of the combination of vitamin D intake with exercise in diabetic patients.

Type 2 diabetic patients are known to have a tendency to develop cardiovascular (CV) disease (CVD), and related unfavourable outcomes such as heart failure, myocardial infarction (MI), cerebrovascular events (e.g. stroke), and related mortality. Long- term clinical trials have revealed contradictory findings regarding the relationship between glycemic control and CV benefits due to variations in the key characteristics of the study population. During the last decade, number of pharmacological agents used for glucose- lowering in the treatment of type 2 diabetes mellitus (T2DM) has increased owing to the introduction of dipeptidyl peptidase- IV (DPP- IV) inhibitors, glucagon- like peptide- 1 (GLP- 1) receptor agonists, and sodium-glucose co-transporter 2 (SGLT- 2) inhibitors. This review aims to focus on the mechanisms of action of these drugs in the cardiovascular system and the trials evaluating their impact on CVD. Furthermore, trials in the last decade evaluating the impact of traditional glucose- lowering drugs on CVD are included. For this purpose, we searched PubMed for articles in English using the search terms "type 2 diabetes mellitus, glucose- lowering drugs, antidiabetic medications, cardiovascular, cardiovascular disease, cardiovascular system" between inception to September 2016. We also searched separately for each medication in addition to the keyword "cardiovascular disease" on PubMed. To identify further articles, we hand searched related citations in review articles and commentaries. Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.org.

Compounds other than macronutrients have been shown to influence blood glucose concentrations and insulin sensitivity in people with diabetes, with caffeine being one such substance. The present study systematically reviewed the evidence of the effects of caffeine on blood glucose concentrations and/or insulin sensitivity in people with diabetes. Four databases, including MEDLINE and EMBASE, were searched up to 1 February 2012. Randomised controlled trials (RCTs) investigating the effects of caffeine on blood glucose and/or insulin sensitivity in humans, diagnosed with type I, type II or gestational diabetes mellitus (GDM), were included. Quality assessment and data extraction were conducted and agreed by both authors. Of 253 articles retrieved, nine trials (134 participants) were identified. Trials in people with type II diabetes demonstrated that the ingestion of caffeine (approximately 200-500 mg) significantly increased blood glucose concentrations by 16-28% of the area under the curve (AUC) and insulin concentrations by 19-48% of the AUC when taken prior to a glucose load, at the same time as decreasing insulin sensitivity by 14-37%. In type I diabetes, trials indicated enhanced recognition and a reduced duration of hypoglycaemic episodes following ingestion of 400-500 mg caffeine, without altering glycated haemoglobin. In GDM, a single trial demonstrated that approximately 200 mg of caffeine induced a decrease in insulin sensitivity by 18% and a subsequent increase in blood glucose concentrations by 19% of the AUC. Evidence indicates a negative effect of caffeine intake on blood glucose control in individuals with type II diabetes, as replicated in a single trial in GDM. Larger-scale RCTs of longer duration are needed to determine the effects of timing and dose. Early indications of a reduced duration and an improved awareness of hypoglycaemia in type I diabetes require further confirmation. © 2013 The Authors Journal of Human Nutrition and Dietetics © 2013 The British Dietetic Association Ltd.

The present study was aimed at characterizing the effects of beta-endorphin on plasma glucose, insulin and glucagon plasma levels in subjects with type-2 diabetes mellitus. Infusion of 0.5 mg/h human beta-endorphin produced significant and simultaneous increments in both insulin and glucagon concentrations and decreased plasma glucose levels (-18 +/- 4 mg/dl, 60 min level, p less than 0.01). When the same diabetics were rendered euglycemic by an insulin infusion (1 mU/kg/min), beta-endorphin did not produce the expected decrease in plasma glucose concentrations nor raise plasma insulin levels; only the response of glucagon was preserved. Normal subjects were rendered hyperglycemic by an intravenous glucose infusion to match the plasma glucose levels of diabetic subjects. In this condition, beta-endorphin produced a significant increase of insulin concentrations, whereas glucagon remained suppressed. The intravenous administration of the long-acting met-enkephalin analogue DAMME (0.25 mg) blunted the hormonal responses to the subsequent beta-endorphin infusion in diabetic patients, although the inhibition was short-lived (30-40 min). Naloxone (5 mg), an opiate antagonist, did not produce any significant change in the insulin and glucagon responses to beta-endorphin, while somatostatin (0.25 mg/h) completely abolished the hormonal responses to the opioid.(ABSTRACT TRUNCATED AT 250 WORDS)

Type 2 diabetes mellitus is a polygenic metabolic disorder resulting from oxidative stress, the root cause of insulin resistance, β-cell dysfunction and impaired glucose tolerance. The aim of this study was to investigate the role of oxidative stress-related genes ALOX5, ALOX5AP, GPX1, GPX3 and MPO in type 2 diabetes mellitus susceptibility in the Chinese Han population. A total of 396 type 2 diabetes mellitus patients and 678 controls were recruited. The ALOX5 rs10900213, ALOX5AP rs4293222, GPX1 rs1050450, GPX3 rs3828599 and MPO rs2107545 gene polymorphisms were genotyped. We found one single-nucleotide polymorphism in the MPO gene was associated with type 2 diabetes mellitus susceptibility [rs2107545: odds ratio = 1.563 (1.166-2.096); p = 0.003], after adjusting for covariates. Furthermore, we also considered the likely complexity of effects of genetic and conventional risk factors in type 2 diabetes mellitus-related vascular complications, such as carotid plaques. Our analysis revealed that the GPX1 rs1050450 and MPO rs2107545 were significantly associated with increased risk of carotid plaques in type 2 diabetes mellitus patients. Our study presents novel evidence for main effects of MPO gene on type 2 diabetes mellitus susceptibility. Furthermore, our study supported the association between variants of oxidative stress-related genes ( GPX1 and MPO) and carotid plaques in type 2 diabetes mellitus patients, which indicated a modulation of type 2 diabetes mellitus-related vascular complication susceptibility by genetic predisposition.

Metabolic complications, including type 2 diabetes mellitus and metabolic syndrome, are increasingly recognized among HIV-infected individuals. Low vitamin D levels increase the risk of type 2 diabetes mellitus, and vitamin D supplementation has been shown to decrease the risk of type 2 diabetes mellitus in patients without HIV infection. The primary objective was to determine whether vitamin D deficiency (serum 25-hyrdoxyvitamin D <20 ng/ml) was associated with type 2 diabetes mellitus among HIV-infected patients. Our secondary objective was to determine whether vitamin D deficiency was associated with metabolic syndrome in HIV. We conducted a cross-sectional study among participants enrolled in the prospective Modena (Italy) HIV Metabolic Clinic Cohort. Clinical and laboratory data, including history of type 2 diabetes mellitus, fasting blood glucose, components of metabolic syndrome, and 25-hydroxyvitamin D levels, were obtained for all participants. After adjusting for vitamin D supplementation, sex, age, body mass index, and hepatitis C virus co-infection, vitamin D deficiency was associated with type 2 diabetes mellitus [adjusted odds ratio (OR) 1.85; 95% confidence interval (CI) 1.03-3.32; P = 0.038]. The association between vitamin D deficiency and metabolic syndrome was not significant after adjusting for vitamin D supplementation, sex, age and body mass index (adjusted OR 1.32; 95% CI 1.00-1.75; P = 0.053). Our study demonstrates an association between vitamin D deficiency and type 2 diabetes mellitus. Clinical trials are needed to better characterize the association between vitamin D deficiency and type 2 diabetes mellitus in HIV infection and to evaluate whether vitamin D is able to prevent or delay the onset of type 2 diabetes mellitus.

The purpose of this study was to examine self-care behaviors of adults with type 2 diabetes mellitus living in the Metropolitan Area of Thessaloniki in Northern Greece. The Summary of Diabetes Self-Care behaviors measurement was administered to 215 patients, out of which 177 were eligible to participate (87 males). Patients, aged 30 years or more, were recruited through a university hospital day-clinic. Older patients (>65 years), as well as those with "higher educational level" did not distribute their daily carbohydrate intake equally. Nevertheless, they were more likely to adapt to their physician's recommendations regarding medication and to regularly perform suggested blood glucose checking. Exercise patterns were more often found for higher educated, earlier diagnosed males. Younger patients were less likely to follow their healthcare professional's recommendations, regarding diet, medication intake, blood glucose checking, foot care and exercise compared to older patients. These results pose a higher risk for complications and morbidity in younger patients with type 2 diabetes mellitus, who most possibly will require intensive treatment in the future.

Evidence to support the use of vildagliptin monotherapy in the treatment of type 2 diabetes mellitus
Dejager, Sylvie; Schweizer, Anja; Foley, James E
2012-01-01
The efficacy and safety of the dipeptidyl peptidase-4 inhibitor, vildagliptin, as monotherapy have been widely confirmed in a large body of clinical studies of up to 2 years’ duration in various populations with type 2 diabetes mellitus. This paper reviews the data supporting the use of vildagliptin in monotherapy. Consideration based on baseline glycated hemoglobin levels and age is given to patient segments where metformin is not appropriate. In addition, although prediabetes is not an indication, this manuscript briefly reviews some of the existing data showing that the mechanisms at work in diabetic populations are active in patients currently classified as prediabetic, with impaired glucose tolerance or impaired fasting glucose. Finally, the rationale for vildagliptin dosing frequency in monotherapy is discussed. In summary, this review aims to define where in community practice the use of vildagliptin as monotherapy is most desirable, focusing on segments of the population with type 2 diabetes mellitus that might receive the greatest benefit from vildagliptin in the management of their disease.

RNCR3: A regulator of diabetes mellitus-related retinal microvascular dysfunction
DOE Office of Scientific and Technical Information (OSTI.GOV)
Shan, Kun; Shanghai Key Laboratory of Visual Impairment and Restoration, Shanghai; The Fourth School of Clinical Medicine, Nanjing Medical University, Nanjing
Retinal microvascular abnormality is an important pathological feature of diabetic retinopathy. Herein, we report the role of lncRNA-RNCR3 in diabetes mellitus-induced retinal microvascular abnormalities. We show that RNCR3 is significantly up-regulated upon high glucose stress in vivo and in vitro. RNCR3 knockdown alleviates retinal vascular dysfunction in vivo, as shown by decreased acellular capillaries, decreased vascular leakage, and reduced inflammatory response. RNCR3 knockdown decreases retinal endothelial cell proliferation, and reduces cell migration and tube formation in vitro. RNCR3 regulates endothelial cell function through RNCR3/KLF2/miR-185-5p regulatory network. RNCR3 inhibition may be a treatment option for the prevention of diabetes mellitus-induced retinal microvascular abnormalities. - Highlights:more » • RNCR3 expression is significantly up-regulated upon high glucose stress. • RNCR3 knockdown alleviates retinal vascular dysfunction in vivo. • RNCR3 regulates retinal endothelial cell function in vitro. • RNCR3 regulates retinal endothelial cell function via RNCR3/KLF2/miR-185-5p pathway.« less

Women with previous gestational diabetes mellitus (pGDM) are at increased risk of developing type 2 diabetes later in life. The aim of this study was to determine if circulating levels of metabolic hormones 12 weeks following a GDM pregnancy are associated with an increased risk of type 2 diabetes 8-10 years later. Fasting plasma concentrations of glucose, insulin, C-peptide, ghrelin, GIP, GLP-1, glucagon, leptin, PAI-1, resistin and visfatin were measured in 98 normal glucose tolerant women, 12 weeks following an index GDM pregnancy. Women were assessed every 2 years for up to 10 years for development of overt type 2 diabetes. After a median follow-up period of 8.7 years, 22.5% of women with a pGDM pregnancy developed type 2 diabetes. Significant risk factors for the development of type 2 diabetes were fasting plasma glucose levels >5 mmol/L during pregnancy and at 12 weeks post-pregnancy. In addition, higher C-peptide levels and lower ghrelin levels at 12 weeks post-pregnancy were also significant risk factors for the development of type 2 diabetes. Fasting plasma glucose during pregnancy and post-partum, and post-partum C-peptide and ghrelin levels were significant risk factors for the development of type 2 diabetes in women with pGDM. This is the first report that identifies C-peptide and ghrelin as potential biomarkers for the prediction of type 2 diabetes in women with a history of GDM. © 2014 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

To explore the impact of perioperative average blood-glucose level on the prognosis of patients with hip fracture and diabetes mellitus. A retrospective analysis was made on the clinical data of 244 patients with hip fracture and diabetes mellitus who accorded with the inclusion criteria between September 2009 and September 2012. Of 244 patients, 125 patients with poorly controlled fasting blood-glucose (average fasting blood-glucose level > 7.8 mmol/L) were assigned in group A, and 119 patients with well controlled fasting blood-glucose (average fasting blood-glucose level ≤ 7.8 mmol/L) were assigned in group B according to "China guideline for type 2 diabetes" criteria. There was no significant difference in gender, age, disease duration of diabetes mellitus, serum albumin, fracture type and disease duration, surgical procedure, anaesthesia, and complications between 2 groups (P > 0.05). Group A had a higher hemoglobin level and fewer patients who can do some outdoor activities than group B (t = -2.353, P = 0.020; χ2 = 4.333, P = 0.037). The hospitalization time, days to await surgery, stitch removal time, the postoperative complication rate, the mortality at 1 month and 1 year after operation, and ambulatory ability at 1 year after operation were compared between the 2 groups. A total of 223 patients (114 in group A and 109 in group B) were followed up 12-15 months (mean, 13.5 months). The days to await surgery of group A were significantly more than those of group B (t = -2.743, P=0.007), but no significant difference was found in hospitalization time and stitch removal time between 2 groups (P > 0.05). The postoperative complication rate of group A (19.2%, 24/125) was significantly higher than that of group B (8.4%, 10/119) (χ2 =5.926, P = 0.015). Group A had a higher mortality at 1 month after operation than group B (6.1% vs. 0) (χ2 = 5.038, P = 0.025), but no significant difference was shown at 1 year after operation between groups A and B (8.8% vs. 4.6%) (χ2 = 1.555, P = 0.212). At 1 year after operation in patients who can do some outdoor activities, the proportions of patients who turned to do some indoor activities was 19.2% (15/78) in the group A and 13.5% (12/89) in group B, showing no significant difference (χ2 = l.013, P = 0.314). Poorly controlled perioperative fasting blood-glucose may lead undesirable influence on the prognosis of patients with hip fracture and diabetes mellitus. In order to reduce the complication rate and other accidents, the fasting blood-glucose level should be controlled to 7.8 mmol/L or less.

The treatment of type 1 diabetes mellitus with agents approved for type 2 diabetes mellitus.
Munir, Kashif M; Davis, Stephen N
2015-01-01
The management of type 1 diabetes remains a challenge for clinicians. Current practice is to administer insulin analogues to best mimic normal physiological insulin profiles. However, despite our best efforts the majority of individuals with type 1 diabetes continue to suffer from suboptimal glucose control, significant hypoglycemia and microvascular tissue complications of the disease. There is thus a significant unmet need in the treatment of T1DM to obtain better glycemic control. We discuss the use of α-glucosidase inhibitors, dipeptidyl-peptidase inhibitors, glucagon-like peptide 1 agonists, biguanides, thiazolidinediones and sodium glucose co-transporter 2 inhibitors in individuals with T1DM. Non-insulin therapies present a unique and exciting adjunctive treatment for individuals with type 1 diabetes. Although data are scarce, the classes of medications discussed help to lower glucose, decrease glycemic excursions and in some cases improve body weight, along with allowing dose reductions in total daily insulin. Glucagon-like peptide 1 agonists and sodium glucose co-transporter 2 inhibitors, in particular, have been demonstrated to provide clinical improvements in individuals with T1DM and we feel their use can be explored in obese, insulin-resistant patients with T1DM, those with frequent and significant glycemic excursions or individuals with persistently elevated hemoglobin A1c.

Recently, it has become clear that mild abnormal glucose tolerance increases the incidence of perinatal maternal-infant complications, and so the definition and diagnostic criteria of gestational diabetes mellitus (GDM) have been changed. Therefore, in patients with GDM and pregnant women with diabetes mellitus, even stricter glycemic control than before is required to reduce the incidence of perinatal maternal-infant complications. Strict glycemic control cannot be attained without an indicator of glycemic control; this review proposes a reliable indicator. The gold standard indicator of glycemic control in patients with diabetes mellitus is hemoglobin A1c (HbA1c); however, we have demonstrated that HbA1c does not reflect glycemic control accurately during pregnancy because of iron deficiency. It has also become clear that glycated albumin, another indicator of glycemic control, is not influenced by iron deficiency and therefore might be a better indicator of glycemic control in patients with GDM and pregnant women with diabetes mellitus. However, large-population epidemiological studies are necessary in order to confirm our proposal. Here, we outline the most recent findings about the indicators of glycemic control during pregnancy including fructosamine and 1,5-anhydroglucitol. PMID:26240701

Diabetes and renal tubular cell apoptosis
Habib, Samy L
2013-01-01
Apoptosis contributes to the development of diabetic nephropathy, but the mechanism by which high glucose induces apoptosis is not fully understood. Apoptosis of tubular epithelial cells is a major feature of diabetic kidney disease, and hyperglycemia triggers the generation of free radicals and oxidant stress in tubular cells. Hyperglycemia and high glucose in vitro also lead to apoptosis, a form of programmed cell death. High glucose similar to those seen with hyperglycemia in people with diabetes mellitus, lead to accelerated apoptosis, a form of programmed cell death characterized by cell shrinkage, chromatin condensation and DNA fragmentation, in variety of cell types, including renal proximal tubular epithelial cells.

Diabetes mellitus (DM) is a major metabolic disorder currently affecting over 200 million people worldwide. Approximately 90% of all diabetic patients suffer from Type 2 diabetes mellitus (T2DM). The world's economy coughs out billions of dollars annually to diagnose, treat and manage patients with diabetes. It has been shown that the naturally occurring gut hormones incretins, glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) can preserve the morphology and function of pancreatic beta cell. In addition, GIP and GLP-1 act on insulin receptors to facilitate insulin-receptor binding, resulting in optimal glucose metabolism. This review examines the medicinal chemistry and roles of incretins, specifically, GLP-1 and drugs which can mimic its actions and prevent its enzymatic degradation. The review discussed GLP-1 agonists such as exenatide, liraglutide, taspoglutide and albiglutide. The paper also identified and reviewed a number of inhibitors, which can block dipeptidyl peptidase 4 (DPP-4), the enzyme responsible for the rapid degradation of GLP-1. These DPP-4 inhibitors include sitagliptin, saxagliptin, vildagliptin and many others which are still in the experimental phase. PMID:21966329

Pupillary reactions and hemodynamic parameters in the ophthalmic and central retinal arteries were studied in patients with types 1 and 2 diabetes mellitus. The pupillary dilatation test in the dark and 2.5% irifrin and 1% mydriacyl tests revealed a reduction in the papillary dilatation amplitude in hyperglycemia in patients with diabetic retinopathy. The amplitude of pupillary dilatation did not change during all pupil reactions in patients without diabetic retinopathy with a glycemic gradient. Pupillary dysfunction was detected in patients with diabetic retinopathy, which is a poor predictor for microangiopathy. Color Doppler mapping is a technique for studying blood flow, which is widely used in most of research institutions now. The procedure for studying the ocular microcirculatory bed in relation to blood glucose levels is an innovation in examining eye hemodynamics in patients with diabetes mellitus.

Maternal outcomes and follow-up after gestational diabetes mellitus
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.

Self testing for diabetes mellitus.
Davies, M; Alban-Davies, H; Cook, C; Day, J
1991-01-01
OBJECTIVE--To develop a simple, economically viable, and effective means of population screening for diabetes mellitus. DESIGN--A postal request system for self testing for glycosuria with foil wrapped dipsticks. Preprandial and postprandial tests were compared with a single postprandial test. The subjects were instructed how to test, and a result card was supplied on which to record and return the result. All those recording a positive test result and 50 people recording a negative result were invited for an oral glucose tolerance test. SETTING--General practice in east Suffolk, list size 11534. PATIENTS--All subjects aged 45-70 years registered with the practice were identified by Suffolk Family Health Services Authority (n = 3057). The 73 subjects known to have diabetes from the practice's register were excluded, leaving 2984 subjects, 2363 (79.2%) of whom responded. 1167 subjects completed the single test and 1196 the two tests. MAIN OUTCOME MEASURES--Response rate and number of patients with glycosuria. Sensitivity, specificity, and positive predictive value of a single postprandial test and preprandial and postprandial tests. Number of new cases of diabetes identified and cost of screening. RESULTS--Of the patients completing the single postprandial test, 29 had a positive result, an oral glucose tolerance test showed that eight (28%) had diabetes, six (21%) impaired glucose tolerance, and 14 (48%) normal glucose tolerance. 44 of the group who tested before and after eating had a positive result; nine (20%) had diabetes, five (11%) impaired tolerance, and 26 (11%) normal tolerance. Screening cost 59p per subject and 81 pounds per case detected. Of the 17 people with previously undiagnosed diabetes, eight were asymptomatic and 11 had not visited their general practitioner in the past three months. CONCLUSIONS--A postal request system for self testing for postprandial glycosuria in people aged 45-70 is a simple and effective method of population screening for diabetes mellitus. PMID:1912918

An 8-yr-old male golden lion tamarin ( Leontopithecus rosalia ) was diagnosed with diabetes mellitus based on hyperglycemia and persistent glycosuria. Initial treatment consisted of the oral antihyperglycemic medications glipizide and metformin that resulted in decreased blood glucose concentrations; however, marked glycosuria persisted. Insufficient improvement on oral antihyperglycemic therapy and poor feasibility of daily subcutaneous insulin therapy led to an investigation into an alternative therapy with extended-release exenatide, a glucagon-like peptide-1 (GLP-1) mimetic, at a dosage of 0.13 mg/kg subcutaneously once per month. Following treatment with exenatide, the persistent glycosuria resolved, the animal maintained normal blood glucose concentrations, and had lower serum fructosamine concentrations compared to pretreatment levels. Based on these findings, extended-release exenatide could be considered as a therapeutic option in nonhuman primates with diabetes mellitus that do not respond to oral antihyperglycemics and in which daily subcutaneous insulin is not feasible.

An update on sodium-glucose co-transporter-2 inhibitors for the treatment of diabetes mellitus.
Hsia, Daniel S; Grove, Owen; Cefalu, William T
2017-02-01
Sodium-glucose co-transporter-2 (SGLT2) inhibitors are the newest class of oral antihyperglycemic agents that have been approved for the treatment of diabetes mellitus. Over the past year, there have been significant developments in both the safety and efficacy of this class of medications that are presented in this review. Apart from data on the glucose-lowering effect of SGLT2 inhibitors, other metabolic benefits have been demonstrated for this class of medications. Moreover, there have been three Food and Drug Administration Drug Safety Communications issued in 2015 that have led to additional drug labeling. The basic mechanism of action, indications, glucose-lowering benefits, other metabolic benefits, and adverse side-effects of SGLT2 inhibitors are presented in this review. SGLT2 inhibitors are medications that have a unique mechanism of action and that lower glucose independent of insulin. Given the recent findings on efficacy and benefits, these agents are rapidly establishing their role in the treatment of diabetes. Especially in patients with type 2 diabetes not willing or not ready to start insulin, SGLT2 inhibitors may be another option in those patients requiring additional glucose lowering and in those with acceptable risk factor profiles. Although there appears to be some positive benefits in cardiovascular endpoints, more research on the long-term outcomes in people taking SGLT2 inhibitors is warranted.

Sodium glucose cotransporter SGLT1 as a therapeutic target in diabetes mellitus
Song, Panai; Onishi, Akira; Koepsell, Hermann; Vallon, Volker
2016-01-01
Introduction Glycemic control is important in diabetes mellitus to minimize the progression of the disease and the risk of potentially devastating complications. Inhibition of the sodium–glucose cotransporter SGLT2 induces glucosuria and has been established as a new anti-hyperglycemic strategy. SGLT1 plays a distinct and complementing role to SGLT2 in glucose homeostasis and, therefore, SGLT1 inhibition may also have therapeutic potential. Areas covered This review focuses on the physiology of SGLT1 in the small intestine and kidney and its pathophysiological role in diabetes. The therapeutic potential of SGLT1 inhibition, alone as well as in combination with SGLT2 inhibition, for anti-hyperglycemic therapy are discussed. Additionally, this review considers the effects on other SGLT1-expressing organs like the heart. Expert opinion SGLT1 inhibition improves glucose homeostasis by reducing dietary glucose absorption in the intestine and by increasing the release of gastrointestinal incretins like glucagon-like peptide-1. SGLT1 inhibition has a small glucosuric effect in the normal kidney and this effect is increased in diabetes and during inhibition of SGLT2, which deliver more glucose to SGLT1 in late proximal tubule. In short-term studies, inhibition of SGLT1 and combined SGLT1/SGLT2 inhibition appeared to be safe. More data is needed on long-term safety and cardiovascular consequences of SGLT1 inhibition.

Diabetes mellitus is one of the most common non-communicable diseases globally. This study seeks to estimate the prevalence of impaired fasting glycemia and type 2 diabetes mellitus in genetically isolated populations in Jordan: the Circassians and Chechans. Data were analyzed from a cross-sectional study that included a random sample of adult Circassians and Chechans. A subject was defined as affected by diabetes mellitus if diagnosis was known to patient or, according to the American Diabetes Association definition. Impaired fasting glucose was defined as a fasting serum glucose level of ≥6.1 mmol/L (100 mg/dl) but <7 mmol/L. HbA(1c) >7% was defined as 'unsatisfactory' metabolic control. The prevalence of impaired fasting glycemia was 18.5% for Circassians and 14.6% for Chechans. Prevalence of diabetes was 9.6% for Circassians and 10.1% for Chechans. The prevalence of impaired fasting glycemia and diabetes were significantly higher in men, older age groups, married, subjects of lower educational level, past smokers, and subjects with obesity. Low high-density lipoprotein cholesterol was the most common abnormality in the two populations. The homogenous, genetically isolated Circassian and Chechan populations sharing the same environmental influences suggest a role for genetic risk factors for diabetes. Thus these two populations are suitable for additional genetics studies that may lead to the identification of novel risk factors for type 2 diabetes. In addition, more than half of patients with diabetes were with unsatisfactory control. Therefore, they are likely to benefit from programs encouraging healthy weight and physical activity.

Gestational diabetes mellitus (GDM) is a risk factor for perinatal complications. In several countries, the criteria for the diagnosis of GDM have been in flux, the American Diabetes Association (ADA) thresholds recommended in 2000 being lower than those of the National Diabetes Data Group (NDDG) that have been in use since 1979. We sought to determine the extent to which infants of women meeting only the ADA criteria for GDM are at increased risk of neonatal complications. In a multiethnic cohort of 45,245 women who did not meet the NDDG criteria and were not treated for GDM, we conducted nested case-control studies of three complications of GDM that occurred in their infants: macrosomia (birthweight >4,500 g, n = 494); hypoglycaemia (plasma glucose <2.2 mmo/l, n = 488); and hyperbilirubinaemia (serum bilirubin > or =342 micromol/l (20 mg/dl), n = 578). We compared prenatal glucose levels of the mothers of these infants and mothers of 884 control infants. Women with GDM by ADA criteria only (two or more glucose values exceeding the threshold) had an increased risk of having an infant with macrosomia (odds ratio OR = 3.40, 95% CI = 1.55-7.43), hypoglycaemia (OR = 2.61, 95% CI = 0.99-6.92) or hyperbilirubinaemia (OR = 2.22, 95% CI = 0.98-5.04). Glucose levels 1 h after the 100-g glucose challenge that exceeded the ADA threshold were particularly strongly associated with each complication. These results lend support to the ADA recommendations and highlight the importance of the 1-h glucose measurement in a diagnostic test for GDM.

To achieve good metabolic control in diabetes and maintain it in the long term, a combination of changes in lifestyle and pharmacological treatment is necessary. The need for insulin depends upon the balance between insulin secretion and insulin resistance. Insulin is considered the most effective glucose-lowering therapy available and is required by people with type 1 diabetes mellitus to control their blood glucose levels; yet, many people with type 2 diabetes mellitus will also eventually require insulin therapy, due to the progressive nature of the disease. A variety of long-acting insulins is currently used for basal insulin therapy (such as insulin glargine, degludec, and detemir), each having sufficient pharmacodynamic and pharmacokinetic profiles to afford lower intrapatient variability and an extended duration of action. The new glargine-300 formulation was developed to have a flatter and more extended time-action profile than the original glargine-100, and these characteristics may translate into more stable and sustained glycemic control over a 24 h dosing interval. The objective of this comprehensive review was to summarize the available evidence on the clinical efficacy and safety of glargine-300 versus glargine-100 from the EDITION clinical trial program, in patients with type 1 and type 2 diabetes mellitus.

Adiponectin complexes composition in Japanese-Brazilians regarding their glucose tolerance status.
Crispim, Felipe; Vendramini, Marcio F; Moisés, Regina S
2013-04-09
Adiponectin circulates in different multimer complexes comprised of low molecular weight trimeric form (LMW), hexamer of middle molecular weight (MMW) and high molecular weight multimers (HMW). In Japanese-Brazilians, a population with high prevalence of glucose metabolism disturbances, we examined the associations of total adiponectin and its multimers with diabetes mellitus. Two study groups were examined: 26 patients with diabetes mellitus (DM,14 women and 12 men, aged 55.3 ± 8.6 years) and 27 age-matched control subjects with normal glucose tolerance (NGT,12 women and 15 men, aged 54.0 ± 9.2 years). We found no significant differences in total [NGT: 6.90 ug/ml (4.38-13.43); DM: 5.38 ug/ml (3.76-8.56), p = 0.35], MMW [NGT:2.34 ug/ml (1.38-3.25); DM: 1.80 ug/ml (1.18-2.84), p = 0.48] or LMW adiponectin [NGT: 2.07 ug/ml (1.45-3.48), DM: 2.93 ug/ml (1.78-3.99), p = 0.32] between groups. In contrast, HMW adiponectin levels were significantly lower in patients with DM [TGN: 2.39 ug/ml (1.20-4.75); DM: 1.04 ug/ml (0.42-1.60), p = 0.001]. A logistic regression analysis was done to identify independent associations with diabetes mellitus. The results showed that HOMA-IR and HMW adiponectin in women were independently associated with diabetes mellitus. The current investigation demonstrates that in Japanese-Brazilians HMW adiponectin is selectively reduced in individuals with type 2 diabetes, while no differences were found in MMW and LMW adiponectin isoforms.

Renal glucose reabsorption was measured with the stepped hyperglycemic clamp in 15 subjects with type 2 diabetes mellitus (T2DM) and 15 without diabetes after 2 days and after more chronic (14 days) treatment with empagliflozin. Patients with T2DM had significantly greater maximal renal glucose transport (Tm G ) compared with subjects without diabetes at baseline (459 ± 53 vs. 337 ± 25 mg/min; P < 0.05). Empagliflozin treatment for 48 h reduced the Tm G in both individuals with and without diabetes by 44 ± 7 and 53 ± 6%, respectively (both P < 0.001). Tm G was further reduced by empagliflozin in both groups on day 14 (by 65 ± 5 and 75 ± 3%, respectively). Empagliflozin reduced the plasma glucose concentration threshold for glucose spillage in the urine similarly in individuals with T2DM and without diabetes to <40 mg/dL, which is well below the normal fasting plasma glucose concentration. In summary, sodium-glucose transporter-2 inhibition with empagliflozin reduces both Tm G and threshold for glucose spillage in the urine in patients with T2DM and those without diabetes. © 2017 by the American Diabetes Association.

Antipsychotic metabolic effects: weight gain, diabetes mellitus, and lipid abnormalities.
McIntyre, R S; McCann, S M; Kennedy, S H
2001-04-01
To review published and nonpublished literature describing changes in weight, glucose homeostasis, and lipid milieu with antipsychotics. A Medline search was completed using the words weight gain, diabetes mellitus, cholesterol, triglycerides, risperidone, clozapine, olanzapine, quetiapine, ziprasidone, predictors, prolactin, obesity, and conventional antipsychotics. Publications, including original articles, review articles, letters to the editor, abstracts or posters presented at professional meetings in the last 4 years, and references from published articles, were collected. Manufacturers, including Eli Lilly Canada Inc, JanssenOrtho Inc, Pfizer Canada Inc, AstraZeneca Inc, and Novartis Pharmaceuticals, were contacted to retrieve additional medical information. The topic of antipsychotic-induced weight gain is understudied, and there are relatively few well-controlled studies. Weight gain as a side effect has been described with both conventional and atypical antipsychotics. Moreover, some atypical antipsychotics are associated with de novo diabetes mellitus and increased serum triglyceride levels. Predictors of weight gain may be age, baseline body mass index, appetite stimulation, previous antipsychotic exposure, and antipsychotic treatment duration. Significant weight gain is reported with the existing atypical antipsychotics. The weight gain described is highly distressing to patients, may reduce treatment adherence, and may increase the relative risk for diabetes mellitus and hypertriglyceridemia. Physicians employing these agents should routinely monitor weight, fasting blood glucose, and lipid profiles.

CKD in diabetes: diabetic kidney disease versus nondiabetic kidney disease.
Anders, Hans-Joachim; Huber, Tobias B; Isermann, Berend; Schiffer, Mario
2018-06-01
The increasing global prevalence of type 2 diabetes mellitus (T2DM) and chronic kidney disease (CKD) has prompted research efforts to tackle the growing epidemic of diabetic kidney disease (DKD; also known as diabetic nephropathy). The limited success of much of this research might in part be due to the fact that not all patients diagnosed with DKD have renal dysfunction as a consequence of their diabetes mellitus. Patients who present with CKD and diabetes mellitus (type 1 or type 2) can have true DKD (wherein CKD is a direct consequence of their diabetes status), nondiabetic kidney disease (NDKD) coincident with diabetes mellitus, or a combination of both DKD and NDKD. Preclinical studies using models that more accurately mimic these three entities might improve the ability of animal models to predict clinical trial outcomes. Moreover, improved insights into the pathomechanisms that are shared by these entities - including sodium-glucose cotransporter 2 (SGLT2) and renin-angiotensin system-driven glomerular hyperfiltration and tubular hyper-reabsorption - as well as those that are unique to individual entities might lead to the identification of new treatment targets. Acknowledging that the clinical entity of CKD plus diabetes mellitus encompasses NDKD as well as DKD could help solve some of the urgent unmet medical needs of patients affected by these conditions.

Medical management for children with type 1 diabetes mellitus, including insulin administration to control high blood glucose levels (BGL), is crucial. However, a child-controlled behavioural strategy, like physical activity, to maintain target BGL may be warranted. To demonstrate, pre- and post-activity BGL were collected for 73 children aged 8- to 14-years attending a diabetes camp. Change in BGL across one session of a free-play swimming activity was analysed. Average BGL was significantly reduced from 197.18 mg/dl to 177.78 mg/dl across one 45 min session, and male gender predicted larger reductions. With safety precautions and within the context of appropriate medical management, free-play activity could be used as a strategy for maintaining target BGL.

Glycated albumin (GA) is an indicator of glycemic control, which has some specific characters in comparison with HbA1c. Since glucocorticoids (GC) promote protein catabolism including serum albumin, GC excess state would influence GA levels. We therefore investigated GA levels in patients with Cushing's syndrome. We studied 16 patients with Cushing's syndrome (8 patients had diabetes mellitus and the remaining 8 patients were non-diabetic). Thirty-two patients with type 2 diabetes mellitus and 32 non-diabetic subjects matched for age, sex and BMI were used as controls. In the patients with Cushing's syndrome, GA was significantly correlated with HbA1c, but the regression line shifted downwards as compared with the controls. The GA/HbA1c ratio in the patients with Cushing's syndrome was also significantly lower than the controls. HbA1c in the non-diabetic patients with Cushing's syndrome was not different from the non-diabetic controls, whereas GA was significantly lower. In 7 patients with Cushing's syndrome who performed self-monitoring of blood glucose, the measured HbA1c was matched with HbA1c estimated from mean blood glucose, whereas the measured GA was significantly lower than the estimated GA. We clarified that GA is set lower in relation to plasma glucose levels in patients with Cushing's syndrome. Copyright © 2013 Elsevier B.V. All rights reserved.

Background Early screening of type 2 diabetes mellitus (DM) is essential for improved prognosis and effective delay of clinical complications. However, testing for high glycemia often requires invasive and painful blood testing, limiting its large-scale applicability. We have combined new, unpublished data with published data comparing salivary glucose levels in type 2 DM patients and controls and/or looked at the correlation between salivary glucose and glycemia/HbA1c to systematically review the effectiveness of salivary glucose to estimate glycemia and HbA1c. We further discuss salivary glucose as a biomarker for large-scale screening of diabetes or developing type 2 DM. Methods and Findings We conducted a meta-analysis of peer-reviewed published articles that reported data regarding mean salivary glucose levels and/or correlation between salivary glucose levels and glycemia or HbA1c for type 2 DM and non-diabetic individuals and combined them with our own unpublished results. Our global meta-analysis of standardized mean differences on salivary glucose levels shows an overall large positive effect of type 2 DM over salivary glucose (Hedge's g = 1.37). The global correlation coefficient (r) between salivary glucose and glycemia was large (r = 0.49), with subgroups ranging from medium (r = 0.30 in non-diabetics) to very large (r = 0.67 in diabetics). Meta-analysis of the global correlation between salivary glucose and HbA1c showed an overall association of medium strength (r = 0.37). Conclusions Our systematic review reports an overall meaningful salivary glucose concentration increase in type 2 DM and a significant overall relationship between salivary glucose concentration and associated glycemia/HbA1c values, with the strength of the correlation increasing for higher glycemia/HbA1c values. These results support the potential of salivary glucose levels as a biomarker for type 2 DM, providing a less painful/invasive method for screening type 2 DM, as well as for monitoring blood glucose levels in large cohorts of DM patients.

The aim of the present study was to compare correlation coefficients between anthropometric indices and blood glucose level, and to determine optimal cutoff points of obesity indices in a Chinese population. 2419 males and 5140 females participated in this study in Changchun city. Weight, height, WC (waist circumference) and hip circumference were measured; and BMI (body mass index), WHtR (waist height ratio), WHR (waist hip ratio) and BAI (body adiposity index) were calculated by formulas. FPG (fasting plasma glucose), PPG (post-load plasma glucose), HbA1c (glycosylated hemoglobin) and FSI (fasting serum insulin) were measured. WHtR had the highest partial correlation coefficients with blood glucose and HbA1c in both males and females; however, BAI had the lowest coefficients. AUC (area under receiver operating characteristic curves) for WHtR in screening type 2 diabetes mellitus were higher than other indices. We confirmed that the optimal cutoff points of obesity for WHtR, WHR, WC, BMI and BAI were 0.55, 0.92, 88.1, 25.9 and 28.1 in males, and 0.52, 0.85, 81.6, 24.6 and 31.0 in females, respectively. Central obesity correlates more closely to glucose metabolism in Chinese population than general obesity. WHtR is the best index to predict type 2 diabetes mellitus in Chinese adults. © 2014 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Wiley Publishing Asia Pty Ltd.

Metformin is recommended as the first-line treatment of type 2 diabetes mellitus. Despite its common use, few studies have been conducted to precisely measure the efficacy of metformin versus placebo as a first-line treatment. This study aims to assess the precise effects of metformin monotherapy on glycemic control and weight in drug-naive patients with type 2 diabetes mellitus. Medline ® and Cochrane databases were searched until March 19, 2016 to perform a systematic review and meta-analysis of placebo-controlled randomized trials evaluating metformin monotherapy in drug-naive patients with type 2 diabetes mellitus. Assessed outcomes include glycemic control (fasting plasma glucose, glycosated hemoglobin) and weight. Overall, 16 studies (1140 patients) were selected. Compared to placebo, metformin monotherapy was associated with decreased glycosated hemoglobin by 0.95% at 3 months (95% CI: 0.50 to 1.39, I 2 =87%) and 1.32% at 6 months (95% CI: 1.01 to 1.62, I 2 =71%), and decreased fasting plasma glucose by 1.92mmol/L at 1 month (95% CI: 0.11 to 3.74, I 2 =88%), 1.79mmol/L at 3 months (95% CI: 0.92 to 2.66, I 2 =88%) and 2.14mmol/L at 6 months (95% CI: 1.17 to 3.12, I 2 =82%). No significant difference was demonstrated for the comparisons of weight due to relatively small number of studies retrieved from the literature resulting in insufficient statistical power. This study provides the precise effects of metformin monotherapy regarding the decreases in fasting plasma glucose and glycosated hemoglobin that physician can expected in drug-naive patients with type 2 diabetes mellitus. No evidence was found for the effects on weight. Copyright © 2018 Société française de pharmacologie et de thérapeutique. Published by Elsevier Masson SAS. All rights reserved.

There is an increasing belief that organophosphorus compounds (OPCs) impair glucose homeostasis and cause hyperglycemia and diabetes mellitus. The present study was undertaken to investigate the putative diabetogenic effect of sub-lethal and sub-chronic exposure to paraoxon (POX), an extremely hazardous OPC used in pesticides. The effect of paraoxon on streptozotocin-induced diabetic rats was also examined. Each rat was injected with 100 nmol of POX 5 days per week for 6 weeks. Blood glucose levels and red blood cell acetylcholinesterase activity were measured weekly. Biochemical analysis and morphological studies were performed at the end of the experiment. The results revealed that POX neither induces nor exacerbates diabetes mellitus in experimental rats. Liver and kidney/body weight ratios revealed statistically insignificant differences when compared with controls. Biochemical analysis of urine samples showed a small but not significant increase in protein level in all groups. Urine bilirubin was significantly higher in the diabetes + POX group when compared with the control group. The number of blood cells in urine was significantly higher in the POX-treated group compared with the control group. Hyperglycemia was noted in the diabetes and diabetes + POX groups, but neither in the saline control nor in POX-treated normal rats. Electron microscopy of POX-treated pancreas did not show any morphological changes in beta cells. These results suggest that POX does not cause diabetes mellitus at sub-lethal sub-chronic exposure.

In view of the pathologic basis for the treatment of diabetic neuropathy, it is important to enhance nerve regeneration as well as prevent nerve degeneration. So, in the present study, we have investigated the effect of S-Methylisothiourea Sulfate (selective iNOS inhibitor) and Citicoline, alone and in combination, on Type II diabetes mellitus induced neuropathic pain in wistar rats. Type II diabetes was induced by providing high fat diet and low dose of Streptozotocin for 35 days in rats. Type II diabetes mellitus was assessed in terms of increased glucose, triglycerides, cholesterol, LDL levels, glucose tolerance and decrease in HDL levels. Neuropathy as the complication of type II diabetes was assessed in terms of decreased nerve conduction velocity, mechanical and thermal hyperalgesia and cold allodynia. Oxidative stress was assessed in sciatic nerve and showed increase in LPO and nitrite levels whereas decrease was shown in GSH and catalase activity. Axonal degeneration marked by nerve fibre dearrangement and demyelination was observed in histopathological studies. SMT (iNOS inhibitor), Citicoline and low dose combination of both drugs significantly attenuates the diabetic neuropathic pain assessed in terms of parameters employed. Thus, it may be concluded that simultaneous administration of SMT and Citicoline may provide potential therapeutics for diabetic neuropathic pain. Copyright © 2017 Elsevier B.V. All rights reserved.

Healthy Babies Need Healthy Moms (HBNHM) is an innovative education program that combines the recommended 2-hour postpartum oral glucose tolerance test (OGTT) with diabetes prevention education for women who had gestational diabetes mellitus. During the class, the 2-hour OGTT is performed, and in the time between venipunctures, the women participate in group education focused on evidence-based diabetes prevention strategies that promote healthy family nutrition and lifestyle behavior, importance of preconception care for subsequent pregnancies, and the need for follow-up care for women who screen positive for abnormal glucose levels. The purpose of this article is to describe this model to encourage replication in other diabetes programs. The HBNHM program is a low-budget education program that provides postpartum OGTT screening for women who had gestational diabetes mellitus during their pregnancies while simultaneously offering education designed to improve future outcomes. For those women whose screening is positive for overt diabetes or prediabetes, the educational strategies are directed at encouraging follow-up care. For those patients who have normal screening results, the program is designed to help the patient prevent the future development of type 2 diabetes. Preconception counseling is included in an effort to improve outcomes in future pregnancies and provide patients with the tools needed to help enhance the health of their families.

The rate of type 2 diabetes mellitus among Inuit is 12·2 % in individuals over 50 years of age, similar to the Canadian prevalence. Given marked dietary transitions in the Arctic, we evaluated the dietary and other correlates of not previously diagnosed glucose intolerance, defined as type 2 diabetes mellitus, impaired fasting glucose or impaired glucose tolerance. Cross-sectional analyses were limited to adults with a completed 2 h oral glucose tolerance test and without pre-existing diabetes. Anthropometric assessments, health and medication usage questionnaires and a 24 h dietary recall were administered. Canadian International Polar Year Inuit Health Survey (2007-2008). Inuit adults (n 777). Glucose intolerance was associated with older age and adiposity. Percentage of energy from protein above the Acceptable Macronutrient Distribution Range of 35 %, compared with intake within the range, was associated with increased odds of glucose intolerance (OR=1·98; 95 % CI 1·09, 3·61) in multivariable analyses. Further, cholesterol intake in the highest three quartiles combined (median exposures of 207, 416 and 778 mg/d, respectively) compared with the lowest quartile (median intake of 81 mg/d) was associated with glucose intolerance (OR=2·15; 95 % CI 1·23, 3·78) in multivariable analyses. Past-day traditional food consumption was borderline protective of glucose intolerance (P=0·054) and high fibre intake was not significantly protective (P=0·08). The results contribute to the existing literature on high protein and cholesterol intakes as they may relate to diabetes risk.

Metformin, vildagliptin and their combination are widely used for the treatment of diabetes, but little is known about the metabolic responses to these treatments. In the present study, NMR-based metabolomics was applied to detect changes in the urinary metabolomic profile of a mouse model of diet-induced obesity in response to these treatments. Additionally, standard biochemical parameters and the expression of enzymes involved in glucose and fat metabolism were monitored. Significant correlations were observed between several metabolites (e.g., N-carbamoyl-β-alanine, N1-methyl-4-pyridone-3-carboxamide, N1-methyl-2-pyridone-5-carboxamide, glucose, 3-indoxyl sulfate, dimethylglycine and several acylglycines) and the area under the curve of glucose concentrations during the oral glucose tolerance test. The present study is the first to present N-carbamoyl-β-alanine as a potential marker of type 2 diabetes mellitus and consequently to demonstrate the efficacies of the applied antidiabetic interventions. Moreover, the elevated acetate level observed after vildagliptin administration might reflect increased fatty acid oxidation. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

To identify published studies evaluating the effects of cinnamon on glycaemic control. Literature search. The Medline database was searched using all possible combinations of the words and medical subject headings (MeSH) 'cinnamon', 'diabetes mellitus', 'HbA1C' and 'glucose'. All human or animal studies in which cinnamon was administered as intervention were included. Several animal studies and 5 randomized placebo-controlled trials in humans were found. Most of the animal studies described beneficial effects of cinnamon on glycaemic control. One placebo-controlled trial in patients with type 2 diabetes found that cinnamon intake was associated with favourable effects on fasting plasma glucose. None of the studies reported an improvement in HbA1C. A study in patients with type 1 diabetes found that cinnamon had no effect. Based on the currently available evidence, cinnamon should not be recommended for the improvement ofglycaemic control.

Objective The very presence of an implanted sensor (a foreign body) causes changes in the adjacent tissue that may alter the analytes being sensed. The objective of this study was to investigate changes in glucose availability and local tissue metabolism at the sensor–tissue interface in patients with type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM). Method Microdialysis was used to model implanted sensors. Capillary glucose and subcutaneous (sc) microdialysate analytes were monitored in five T1DM and five T2DM patients. Analytes included glucose, glycolysis metabolites (lactate, pyruvate), a lipolysis metabolite (glycerol), and a protein degradation byproduct (urea). On eight consecutive days, four measurements were taken during a period of steady state blood glucose. Results Microdialysate glucose and microdialysate-to-blood-glucose ratio increased over the first several days in all patients. Although glucose recovery eventually stabilized, the lactate levels continued to rise. These trends were explained by local inflammatory and microvascular changes observed in histological analysis of biopsy samples. Urea concentrations mirrored glucose trends. Urea is neither produced nor consumed in sc tissue, and so the initially increasing urea trend is explained by increased local capillary presence during the inflammatory process. Pyruvate in T2DM microdialysate was significantly higher than in T1DM, an observation that is possibly explained by mitochondrial dysfunction in T2DM. Glycerol in T2DM microdialysate (but not in T1DM) was higher than in healthy volunteers, which is likely explained by sc insulin resistance (insulin is a potent antilipolytic hormone). Urea was also higher in microdialysate of patients with diabetes mellitus compared to healthy volunteers. Urea is a byproduct of protein degradation, which is known to be inhibited by insulin. Therefore, insulin deficiency or resistance may explain the higher urea levels. To our knowledge, this is the first histological evaluation of a human tissue biopsy containing an implanted glucose monitoring device. Conclusions Monitoring metabolic changes at a material–tissue interface combined with biopsy histology helped to formulate an understanding of physiological changes adjacent to implanted glucose sensors. Microdialysate glucose trends were similar over 1-week in T1DM and T2DM; however, differences in other analytes indicated wound healing and metabolic activities in the two patient groups differ. We propose explanations for the specific observed differences based on differential insulin insufficiency/resistance and mitochondrial dysfunction in T1DM versus T2DM. PMID:20920426

The aim was to investigate the association between the CAPN10 gene single nucleotide polymorphisms (SNPs) -44 (rs2975760), -43 (rs3792267), -19 (rs3842570), and -63 (rs5030952) and type 2 diabetes mellitus in an Asian Indian population in Southern India. A total of 1443 subjects, 794 normal glucose tolerant (NGT) and 649 type 2 diabetes mellitus subjects, were randomly selected from the Chennai Urban Rural Epidemiology Study. These subjects were genotyped for the 4 CAPN10 SNPs using polymerase chain reaction-restriction fragment length polymorphism and validated by direct sequencing. None of the 4 SNPs showed any significant differences in the genotypic distribution among the NGT and type 2 diabetes mellitus subjects (P = .20, .86, .34, and .39 for SNPs -44, -43, -19, and -63, respectively). The NGT subjects with the 11 genotype of the SNP -63 had significantly higher 2-hour postload plasma glucose (mean ± SD, 5.66 ± 1.05 mmol/L) levels compared with the combined 12 and 22 genotype group (5.33 ± 1.11 mmol/L, P = .004). The P value remained significant even after adjusting for age, sex, body mass index, smoking, and alcohol consumption (nominal P = .008). No significant difference in the biochemical parameters was observed when the subjects were stratified according to the other SNPs. The 2111 haplotype corresponding to SNPs -44, -43, -19, and -63 showed a significant difference in the proportion among NGT (0.18) and type 2 diabetes mellitus subjects (0.22, nominal P = .014). Although the Bonferroni correction based on the asymptotic test does not preserve this significance, the test based on the empirical distribution remained significant. In conclusion, our study raises the possibility that the 2111 haplotype of SNPs -44, -43, -19, and -63 may be associated with type 2 diabetes mellitus, although none of these SNPs may be individually associated with diabetes.

Prevention of type 2 Diabetes Mellitus: Potential of pharmacological agents.
Samson, Susan L; Garber, Alan J
2016-06-01
People with impaired glucose tolerance or impaired fasting glucose, or "pre-diabetes", are at high risk for progression to type 2 diabetes, as are those with metabolic syndrome or a history of gestational diabetes. Both glucose-lowering and anti-obesity pharmacotherapies have been studied to determine if the onset of type 2 diabetes can be delayed or prevented. Here we review the available data in the field. The most common theme is the reduction in insulin resistance, such as with weight loss, decreasing demands on the beta cell to improve insulin secretion and prolong its function. Overall, therapies which decrease diabetes incidence in high-risk populations delay the onset of diabetes but do not correct the underlying beta cell defect. Copyright © 2016 Elsevier Ltd.

New-onset diabetes mellitus after transplantation (NODAT) is a serious complication following renal transplantation. The aim of this study was to identify the risk factors for the development of NODAT in Korean transplant patients. Recipients who underwent living donor kidney transplantation between January 2009 and April 2012 at Asan Medical Center were reviewed. Diagnosis of NODAT was defined according to the American Diabetes Association criteria. A total of 418 patients were enrolled. NODAT was diagnosed in 85 (20.4 %) patients within 1 year. By multivariate analysis, old age (odds ratio [OR], 1.05; 95 % Confidence interval [CI]: 1.01-1.08), family history of diabetes mellitus (OR, 2.48; 95 % CI: 1.04-5.94), pre-transplant high serum glucose level (OR, 1.04; 95 % CI: 1.01-1.08), and obesity (OR, 3.46; 95 % CI: 1.55-7.73) were independent risk factors for NODAT. Old age, family history of diabetes, pre-transplant high plasma glucose level, and obesity are independent factors associated with the development of diabetes after renal transplantation. In contrast, serum magnesium levels and the use of tacrolimus are not associated with the development of NODAT.

To study the sensitivity and specificity of the modified 100-g oral glucose tolerance test for diagnosis of gestational diabetes mellitus (GDM). Medical records of pregnant women attending the antenatal clinic of King Chulalongkorn Memorial Hospital, Thailand, who underwent a 100-g oral glucose tolerance test (OGTT) during March 2004 to September 2009, were retrospectively reviewed. Three modified criteria were proposed for diagnosis of GDM. The screening efficacy of the modified criteria were assessed, using the National Diabetes Data Group (NDDG) criterion as gold standard. A total of 729 records were reviewed, 511 were included for analysis. Using the NDDG criterion as the gold standard, the modified II criterion has the highest sensitivity of 96.8%, and the highest accuracy of 90.8%. The modified II criterion can detect the same proportion of maternal and neonatal complications, compared to the NDDG criterion. The modified II criterion, using the fasting plasma glucose and 2-hour plasma glucose measurements, showed high sensitivity and accuracy, with moderate specificity for diagnosis of GDM. Its potential use as an alternative to standard 100-g OGTT should be evaluated in the prospective study.

Background: Gynecomastia during adolescence is common though etiology is not clear. We studied the clinical and hormonal profile of adolescent patients with gynecomastia. Methodology: Patients who had onset of breast development between age 10 and 20 years were included in this study. Their clinical profile, biochemical, and hormonal parameters were studied. Results: Of 94 patients with gynecomastia, 4 had hypogonadotropic hypogonadism, 4 had hypergonadotropic hypogonadism, and 1 had fibroadenosis, but in majority (90.4%), no apparent cause for breast enlargement was evident. In the idiopathic group, majority were obese (63%). Fourteen (16%) patients had impaired fasting glucose or impaired glucose tolerance. Another twenty patients had subtle abnormalities (high 1 h glucose or glucose peak at 2 h). Twenty-nine percent of lean and 38% of obese patients had mild abnormalities in glucose profile. Sixty percent of patients had family background of diabetes. Obese patients had lower testosterone as compared to lean patients; however, estradiol, luteinizing hormone, and follicle-stimulating hormone levels were similar in the two groups. Conclusion: Gynecomastia during adolescence is associated with obesity, dysglycemia, and family background of diabetes mellitus. PMID:28217517

Women with prior gestational diabetes mellitus (GDM) have a high risk of developing type 2 diabetes mellitus (DM2) in later life. The study aim was to evaluate the efficacy of a lifestyle intervention for the prevention of glucose disorders (impaired fasting glucose, impaired glucose tolerance or DM2) in women with prior GDM. A total of 260 women with prior GDM who presented with normal fasting plasma glucose at six to twelve weeks postpartum were randomized into two groups: a Mediterranean lifestyle intervention group (n = 130) who underwent an educational program on nutrition and a monitored physical activity program and a control group (n = 130) with a conventional follow-up. A total of 237 women completed the three-year follow-up (126 in the intervention group and 111 in the control group). Their glucose disorders rates, clinical and metabolic changes and rates of adherence to the Mediterranean lifestyle were analyzed. Less women in the intervention group (42.8%) developed glucose disorders at the end of the three-year follow-up period compared with the control group (56.75%), p < 0.05. The multivariate analysis indicated a reduction in the rate of glucose disorders with a BMI of less than 27 kg/m(2) (OR 0.28; 0.12-0.65; p < 0.003), low fat intake pattern (OR 0.30; 0.13-0.70; p < 0.005), low saturated fat pattern (OR 0.30; 0.13-0.69; p < 0.005) and healthy fat pattern (OR 0.34; 0.12-0.94; p < 0.04). Lifestyle intervention was effective for the prevention of glucose disorders in women with prior GDM. Body weight gain and an unhealthy fat intake pattern were found to be the most predictive factors for the development of glucose disorders.

Aims/Introduction Dipeptidyl peptidase-4 inhibitors and glinides are effective in reducing postprandial hyperglycemia. However, little information is available on the comparative effects of the two drugs on the levels of postprandial glucose. The aim of the present study was to compare the effects of sitagliptin and nateglinide on meal tolerance tests in drug-naïve patients with type 2 diabetes mellitus. Materials and Methods The study participants were 19 patients with type 2 diabetes mellitus, which was inadequately controlled by diet and exercise. An open-label, prospective, cross-over trial was carried out to compare the effects of single-dose sitagliptin and nateglinide on the postprandial glucose level and its related hormones during meal tests. Results The change in area under the curve (AUC) of glucose from 0 to 180 min (AUC0–180 min) during the meal test by nateglinide was similar to that by sitagliptin. As expected, the change in active glucagon like peptide-1 was significantly higher after a single-dose of sitagliptin than nateglinide. Then, insulin secretion relative to glucose elevation (ISG) (ΔISG0–180 min: ΔAUC0–180 min insulin/AUC0–180 min glucose) was significantly enhanced by nateglinide compared with sitagliptin. Conversely, glucagon level (ΔAUC0–180 min glucagon) was increased by administration of nateglinide, whereas the glucagon level was reduced by administration of sitagliptin. Conclusions The effects of sitagliptin on postprandial glucose levels were similar to those of nateglinide in drug-naïve type 2 diabetes patients. However, the induced changes in insulin, active glucagon-like peptide-1 and glucagon during meal loading suggest that reduction of postprandial hyperglycemia was achieved by the unique effect of each drug.

Although high-dose glucocorticoids have been reported to cause new-onset diabetes mellitus (glucocorticoid-induced diabetes mellitus), its risk factors have remained to be determined. We investigated the risk factors related to glucocorticoid-induced diabetes mellitus diagnosed within 2 months after the high-dose treatment (newly treated with an initial high dose of > 20 mg prednisolone (PSL) equivalent per day for at least more than 6 months) in collagen vascular diseases. A total of 2,631 patients with collagen vascular diseases was registered between 1986 and 2006 in the Chiba-Shimoshizu Rheumatic Cohort. We analyzed 681 patients newly treated with high-dose glucocorticoid who did not have diabetes mellitus and/or its previous diagnosis (age: 46.3 ± 16.7 years, PSL dose: 40.0 ± 14.1 mg/day). Glucocorticoid-induced diabetes mellitus was diagnosed by two or more glucose measurements in patients with fasting glycaemia ≥ 7 mmol/L and 120 minutes post-load glycaemia ≥ 11.1 mmol/L. Glucocorticoid-induced diabetes mellitus was observed in 26.3% of patients, and the glucocorticoid-induced diabetes mellitus group had higher age, higher BMI, lower rates of females and systemic lupus erythematosus, higher rates of smoking, alcohol use, and microscopic polyangiitis. Multivariate logistic regression analysis demonstrated that the risk of glucocorticoid-induced diabetes mellitus was independently higher in every 10-year increment of initial age with adjusted odds ratio (OR) 1.556 (95% confidence interval: 1.359 - 1.783), in every 1 kg/m2 increment of BMI with OR 1.062 (1.002 - 1.124), in current smoking with OR 1.664 (1.057 - 2.622), and in every 10 mg increment of initial dose of prednisolone with OR 1.250 (1.074 - 1.454). High-dose glucocorticoids caused diabetes mellitus with high prevalence within a short period, and current smokers should be considered at higher risk of glucocorticoidinduced diabetes mellitus in addition to age, BMI, and initial dose.

The combination of continuous glucose monitoring (CGM) and continuous subcutaneous insulin infusion can be used to improve the treatment of patients with diabetes. The aim of this study was to advance an existing preclinical single-port system for clinical application by integrating the sensors of a phosphorescence based CGM system into a standard insulin infusion set. The extracorporeal optical phase fluorimeter was miniaturised and is now comparable with commercial CGM systems regarding size, weight and wear comfort. Sensor chemistry was adapted to improve the adhesion of the sensor elements on the insulin infusion set. In-vitro tests showed a linear correlation of R 2 =0.998 between sensor values and reference glucose values in the range of 0-300mg/dl. Electrical and cytotoxicity tests showed no negative impact on human health. Two single-port devices were tested in each of 12 patients with type 1 diabetes mellitus in a clinical set-up for 12h. Without additional data processing, the overall median absolute relative difference (median ARD) was 22.5%. For some of the used devices the median ARD was even well below 10%. The present results show that individual glucose sensors performance of the single-port system is comparable with commercial CGM systems but further improvements are needed. The new system offers a high extent of safety and usability by combining insulin infusion and continuous glucose measurement in a single-port system which could become a central element in an artificial pancreas for an improved treatment of patients with type 1 diabetes mellitus.

Gestational diabetes mellitus (GDM) is a serious pregnancy disorder, which is linked to stillbirth, birth damage and later development of type 2 diabetes. Rates of GDM have increased dramatically in the past 20 years, related to obesity, sedentary lifestyles and ethnicity. The aim of this integrative review was to identify and to critically review existing self-management programmes for GDM. A search for studies published between 2000 and 2013 was conducted on: PubMed, CINAHL, Medline, OvidSP, ProQuest, SCOPUS and Wiley online library. GDM search terms included gestational diabetes mellitus; GDM, pregnancy diabetes. Search terms for self-management programmes, included educational programmes; lifestyle intervention; exercise, diet, weight management in pregnancy; life-style interventions. Fifty papers were located in the search, and 12 were included in the review. Interventions fell into three main groups: (1) dietary and exercise interventions; (2) self-monitoring of blood glucose levels; and (3) counselling/behavioural interventions. This review found that although interventions varied in approach, most were successful in reducing insulin requirements; in reducing rates of macrosomia and hypertensive disorders, and in improving levels of knowledge and pregnancy outcomes. Only one study found that the intervention did not contribute some positive outcome. Interventions that include adopting a low glycemic index diet and increasing levels of activity appear to be successful at reducing maternal blood glucose levels and reducing insulin requirements during pregnancy. Reducing maternal blood glucose levels, in turn, is associated with a reduction of macrosomia and maternal weight gain.

Diabetes mellitus and hypertension are major risk factors for chronic kidney injury, together accounting for >70% of end-stage renal disease. In this study, we assessed interactions of hypertension and diabetes mellitus in causing kidney dysfunction and injury and the role of endoplasmic reticulum (ER) stress. Hypertension was induced by aorta constriction (AC) between the renal arteries in 6-month-old male Goto-Kakizaki (GK) type 2 diabetic and control Wistar rats. Fasting plasma glucose averaged 162±11 and 87±2 mg/dL in GK and Wistar rats, respectively. AC produced hypertension in the right kidney (above AC) and near normal blood pressure in the left kidney (below AC), with both kidneys exposed to the same levels of glucose, circulating hormones, and neural influences. After 8 weeks of AC, blood pressure above the AC (and in the right kidney) increased from 109±1 to 152±5 mm Hg in GK rats and from 106±4 to 141±5 mm Hg in Wistar rats. The diabetic-hypertensive right kidneys in GK-AC rats had much greater increases in albumin excretion and histological injury compared with left kidneys (diabetes mellitus only) of GK rats or right kidneys (hypertension only) of Wistar-AC rats. Marked increases in ER stress and oxidative stress indicators were observed in diabetic-hypertensive kidneys of GK-AC rats. Inhibition of ER stress with tauroursodeoxycholic acid for 6 weeks reduced blood pressure (135±4 versus 151±4 mm Hg), albumin excretion, ER and oxidative stress, and glomerular injury, while increasing glomerular filtration rate in hypertensive-diabetic kidneys. These results suggest that diabetes mellitus and hypertension interact synergistically to promote kidney dysfunction and injury via ER stress. © 2017 American Heart Association, Inc.

Over 70% of women with gestational diabetes mellitus (GDM) will develop diabetes mellitus (DM), but only 30% follow through with the recommended postpartum oral glucose tolerance testing (OGTT). HbA1c is approved to diagnose DM, and combined with a fasting plasma glucose it can identify 93% of patients with dysglycemia. We tested the hypothesis that a single blood draw to assess for dysglycemia at the postpartum visit could improve testing rates compared with those required to obtain an OGTT at an outside laboratory. Prospective cohort study of all women with GDM who delivered between July 2010 and December 2011. When insurance status required testing at an outside laboratory an OGTT was ordered, when insurance allowed testing at our center a random sugar and HbA1c were drawn at the postpartum visit (SUGAR Protocol). Of the 40 women, 36 attended a postpartum visit. In the SUGAR arm, 19 of 19 (100%) were tested versus 9 of 17 (53%) in the OGTT arm; relative risk of testing was 1.9 (95% confidence interval, 1.2-3.0). 36% were glucose intolerant. This pilot study found that an in-office testing model doubled the rate of postpartum testing in this clinic population, and was reasonably sensitive at detecting dysglycemia.

Glycemic control indicators in patients with neonatal diabetes mellitus
Suzuki, Shigeru; Koga, Masafumi
2014-01-01
Neonatal diabetes mellitus (NDM) is a type of diabetes mellitus caused by genetic abnormality which develops in insulin dependent state within 6 mo after birth. HbA1c is widely used in clinical practice for diabetes mellitus as the gold standard glycemic control indicator; however, fetal hemoglobin (HbF) is the main hemoglobin in neonates and so HbA1c cannot be used as a glycemic control indicator in NDM. Glycated albumin (GA), another glycemic control indicator, is not affected by HbF. We reported that GA can be used as a glycemic control indicator in NDM. However, it was later found that because of increased metabolism of albumin, GA shows an apparently lower level in relation to plasma glucose in NDM; measures to solve this problem were needed. In this review, we outlined the most recent findings concerning glycemic control indicators in neonates or NDM. PMID:24748932

The study included patients with type 2 diabetes mellitus and impaired carbohydrate tolerance associated with arterial hypertension, patients with arterial hypertension, and healthy volunteers. We evaluated the levels of matrix metalloproteinases 2 and 9 (MMP-2, MMP-9), tissue inhibitor of metalloproteinase type 1 (TIMP-1), glucose, insulin, C-peptide, glycated hemoglobin, and spontaneous and mitogen-activated cytokine secretion (IL-2, IL4, IL-6, IL-10, IL-17, TNF-α, and IFN-γ). Patients with type 2 diabetes mellitus in combination with arterial hypertension exhibited maximum TIMP-1 levels and TIMP-1/MMP-2, TIMP-1/ MMP-9 ratios as well as enhanced secretion of TNF-α, IL-6, IL-17 and reduced secretion of IL-10 in comparison with healthy individuals. The observed shifts are probably determined the development of systemic hyperinsulinemia in patients suffering from type 2 diabetes mellitus coupled with arterial hypertension.

Impaired glucose tolerance and overt diabetes mellitus are frequently associated with acro-megaly. The aim of this study was to find out whether these alterations could be reversed after transsphenoidal surgery. Two hundred and thirty-nine acromegalic patients were studied before and 6-12 months after transsphenoidal surgery. Diagnosis of active acromegaly was established on the basis of widely recognized criteria. In each patient, glucose and insulin concentrations were assessed during the 75 γ oral glucose tolerance test (OGTT). To estimate insulin resistance, we used homeostasis model assessment (HOMA-IR) and the quantitative insulin sensitivity check index (QUICKI). At the moment of diagnosis, diabetes mellitus was present in 25% of the acromegalic patients. After surgery, the pre-valence of diabetes mellitus normalized to the level present in the general Polish population. We found a statistically significant reduction after surgery in plasma glucose levels both fasting (89.45 ± 13.92 mg/dL vs. 99.12 ± 17.33 mg/dL, p < 0.001) and during OGTT. Similarly, a prominent reduction in insulin secretion was found after surgery compared to the moment of diagnosis (15.44 ± 8.80 mIU/mL vs. 23.40 ± 10.24 mIU/mL, p < 0.001). After transsphenoidal surgery, there was a significant reduction in HOMA-IR (3.08 vs. 6.76, p < 0.0001) and a significant increase in QUICKI (0.32 vs. 0.29, p < 0.001). There were no statistically significant differences after surgery in fasting glucose and insulin levels between patients with controlled and in-adequately controlled disease. We conclude that in acromegalic patients glucose homeostasis alterations and insulin sensitivity can be normalized after transsphenoidal surgery, even if strict biochemical cure criteria are not fulfilled.

Visual Evoked Potential to Assess Retinopathy in Gestational Diabetes Mellitus.
Hari Kumar, K V S; Ahmad, F M H; Sood, Sandeep; Mansingh, Sudhir
2016-04-01
We evaluated for early retinopathy using the visual evoked potential (VEP) in patients with gestational diabetes mellitus (GDM) and type 2 diabetes mellitus during pregnancy. All patients with GDM and type 2 diabetes seen between June and October of 2014 were included in this cross-sectional, observational study. Patients with secondary diabetes, ocular or major illness were excluded from the study. VEP was recorded in both eyes to derive prominent positive peak latency (P100), amplitude and initial negative deflection (N75) latency. The data were compared with 10 gestational age-matched controls with normal glucose tolerance. Appropriate statistical methods were used for comparison among the 3 groups. The study participants (40 with GDM, 10 with type 2 diabetes, 10 with normal glucose tolerance) had a median (25th to 75th interquartile range) age of 26 (24.3, 30) years, a gestational age of 24.5 (21, 27) weeks and weights of 66.8 (63.4, 71.5) kg. The P100 latencies were comparable among the 3 groups (p=0.0577). However, patients with any diabetes (GDM and type 2 diabetes) had prolonged P100 latencies (p=0.0139) and low P100 amplitudes (p=0.0391) in comparison to controls. P100 latency showed a direct correlation with hyperglycemia (p=0.0118). Our data showed that VEP abnormalities are detectable even in the short-term hyperglycemia of GDM and type 2 diabetes.

This study evaluated the glycemic, insulinemic, and glucagon-like peptide-1 (GLP-1) responses of subjects with type 2 diabetes mellitus to consumption of two diabetes-specific tube-feeding formulas (slowly digested carbohydrate formula [SDC] and diabetes-specific formula [DSF]) and one formula intended for individuals without diabetes (standard formula [STND]). Forty-eight subjects controlled with diet and/or oral antihyperglycemic medications received the SDC, DSF, and STND. Postprandial glucose, insulin, and GLP-1 were measured on three occasions after an overnight fast in a double-blinded, randomized, three-treatment, crossover design. The positive area under the curve for glucose and insulin with the STND was higher (P < 0.001) compared with the SDC and DSF. The adjusted GLP-1 concentration at 60 min was higher for the SDC compared with the DSF and STND (P < 0.05). Both lower-carbohydrate diabetes-specific formulas resulted in a lower postprandial blood glucose response compared with the STND. The formula also rich in slowly digested carbohydrate and monounsaturated and omega-3 fatty acids (SDC) produced significantly lower blood glucose and insulin responses and higher levels of GLP-1 in the presence of significantly lower insulin concentrations. These results support the view that the quantity and quality of carbohydrate and fat may play important roles in the management of patients with type 2 diabetes mellitus and could result in improved beta-cell function over the long term.

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.

Medicinal plants are effective in controlling plasma glucose level with minimal side effects and are commonly used in developing countries as an alternative therapy for the treatment of type 1 diabetes mellitus. The aim of this study is to evaluate the potential antidiabetic and antioxidant impacts of Balanites aegyptiaca and Petroselinum sativum extracts on streptozotocin-induced diabetic and normal rats. The influences of these extracts on body weight, plasma glucose, insulin, total antioxidant capacity (TAC), malondialdehyde (MDA) levels, and liver-pyruvate kinase (L-PK) levels were assessed. Furthermore, the weight and histomorphological changes of the pancreas were studied in the different experimental groups. The herbal preparations significantly reduced the mean plasma glucose and MDA levels and significantly increased the mean plasma insulin, L-PK, and TAC levels in the treated diabetic groups compared to the diabetic control group. An obvious increase in the weight of the pancreas and the size of the islets of Langerhans and improvement in the histoarchitecture were evident in the treated groups compared to untreated ones. In conclusion, the present study provides a scientific evidence for the traditional use of these extracts as antidiabetic and antioxidant agents in type 1 diabetes mellitus.

To describe the state of glycemic control in noncritically ill diabetic patients admitted to the Puerto Rico University Hospital and adherence to current standard of care guidelines for the treatment of diabetes. This was a retrospective study of patients admitted to a general medicine ward with diabetes mellitus as a secondary diagnosis. Clinical data for the first 5 days and the last 24 hours of hospitalization were analyzed. A total of 147 noncritically ill diabetic patients were evaluated. The rates of hyperglycemia (blood glucose ≥180 mg/dL) and hypoglycemia (blood glucose <70 mg/dL) were 56.7 and 2.8%, respectively. Nearly 60% of patients were hyperglycemic during the first 24 hours of hospitalization (mean random blood glucose, 226.5 mg/dL), and 54.2% were hyperglycemic during the last 24 hours of hospitalization (mean random blood glucose, 196.51 mg/dL). The mean random last glucose value before discharge was 189.6 mg/dL. Most patients were treated with subcutaneous insulin, with basal insulin alone (60%) used as the most common regimen. The proportion of patients classified as uncontrolled receiving basal-bolus therapy increased from 54.3% on day 1 to 60% on day 5, with 40% continuing to receive only basal insulin. Most of the uncontrolled patients had their insulin dose increased (70.1%); however, a substantial proportion had no change (23.7%) or even a decrease (6.2%) in their insulin dose. The management of hospitalized diabetic patients is suboptimal, probably due to clinical inertia, manifested by absence of appropriate modification of insulin regimen and intensification of dose in uncontrolled diabetic patients. A comprehensive educational diabetes management program, along with standardized insulin orders, should be implemented to improve the care of these patients.

Omentin is a new adipokine secreted mainly from visceral adipose tissue. Serum omentin is found to be reduced in patients with impaired glucose tolerance, type 2 diabetes mellitus, obesity and insulin resistant states. Despite the fact that pregnancy is also characterized with hyperinsulinemia, literature is lacking about data of omentin levels and its association with insulin resistance in pregnant women. We aimed to evaluate the association of omentin levels and insulin resistance in pregnant women and to compare these levels with those of non-pregnant, non-diabetic women. Uncomplicated pregnant women who admit to our outpatient clinics for routine follow-up were included in the study group. Non-pregnant women without diabetes mellitus were served as control group. Fasting glucose, insulin, omentin levels and HOMA IR were recorded. SPSS 15.0 for Windows was used for statistical analysis. There were 36 pregnant women in the study group and 37 healthy, non-pregnant women in the control group. Serum omentin and fasting glucose levels were significantly decreased and fasting insulin was significantly increased in the study group compared to control group. Omentin might be an indicator of insulin resistance in pregnant women. Larger prospective studies are needed to claim whether omentin can have a clinical use for diagnosis of gestational diabetes mellitus. © J. A.

Low birth weight (BW) and low ponderal index (PI) are associated with increased risk of type 2 diabetes mellitus. This study has two purposes: first to investigate the influence of PI on the risk of gestational diabetes mellitus (GDM); second, to study the association between glucose metabolism and BW in women with previous GDM. GDM cohort: 185 women with GDM in 1978-1996, attending a follow-up study in 2000-2002. Control cohort: 1137 women from a population-based diabetes screening study (Inter99) in a neighbouring county in 1999-2001. BW and birth length were collected from the original midwifery records. BW and PI were stratified into tertiles for analysis. PI in the lower tertiles was associated with an increased risk of GDM [odds ratio 1.59 (95% confidence interval 1.07-2.36, p = 0.021)]. Among women with previous GDM, the area under the curve (AUC) for plasma levels of glucose and insulin during an OGTT was highest for the lower tertiles of BW (for AUCglucose p = 0.048, for AUCinsulin p = 0.047 adjusted for age and BMI). Lower PI is associated with increased risk of GDM. In women with previous GDM, lower BW is associated with a more severe impairment of glucose metabolism one to two decades after the pregnancy complicated by GDM.

To evaluate effect of acarbose on control of glycemia in dogs with diabetes mellitus. Prospective randomized crossover controlled trial. 5 dogs with naturally acquired diabetes mellitus. Dogs were treated with acarbose and placebo for 2 months each: in 1 of 2 randomly assigned treatment sequences. Dogs that weighed < or = 10 kg (22 lb; n = 3) or > 10 kg (2) were given 25 or 50 mg of acarbose, respectively, at each meal for 2 weeks, then 50 or 100 mg of acarbose, respectively, at each meal for 6 weeks, with a 1-month interval between treatments. Caloric intake, type of insulin, and frequency of insulin administration were kept constant, and insulin dosage was adjusted as needed to maintain control of glycemia. Serum glucose concentrations, blood glycosylated hemoglobin concentration, and serum fructosamine concentration were determined. Significant differences in mean body weight and daily insulin dosage among dogs treated with acarbose and placebo were not found. Mean preprandial serum glucose concentration, 8-hour mean serum glucose concentration, and blood glycosylated hemoglobin concentration were significantly lower in dogs treated with insulin and acarbose, compared with insulin and placebo. Semisoft to watery feces developed in 3 dogs treated with acarbose. Acarbose may be useful as an adjunctive treatment in diabetic dogs in which cause for poor glycemic control cannot be identified, and insulin treatment alone is ineffective.

Diabetes Mellitus is a common chronic disease that has become a public health issue. Continuous glucose monitoring improves patient health by stabilizing the glucose levels. Optical methods are one of the painless and promising methods that can be used for blood glucose predictions. However, having accuracies lower than what is acceptable clinically has been a major concern. Using lasers along with multivariate techniques such as Partial Least Square (PLS) can improve glucose predictions. This research involves investigations for developing a novel optical system for accurate glucose predictions, which leads to the development of a small, low power, implantable optical sensor for diabetes patients.

Authors would like to demonstrate the beneficial effect of myo-inositol supplementation in a pregnant woman with insulin-dependent type 2 diabetes mellitus and polycystic ovary syndrome. Insulin and metformin treatment could not achieve normalization of glucose homeostasis for 3 years, and hypoglycemic episodes were frequent. Myo-inositol and folic acid supplementation added to the basic treatment resulted in improved glucose levels in 2 months. At this time she became pregnant. During pregnancy serum glucose levels still improved in the next 2 months. The amniotic membrane ruptured at the 19th gestational week, and pregnancy had to be finished. Developmental disturbances were excluded by the pathologist. She became pregnant again and gave birth to a premature male neonate at the 29th gestational week. The aim of the report was to demonstrate that myo-inositol supplementation may improve the efficacy of the therapy in type 2 diabetes mellitus. Orv. Hetil., 2017, 158(14), 541-545.

To evaluate gamma-glutamyltransferase (GGT), alanine transaminases (ALT) and aspartate transaminases (AST) levels and prevalent gestational diabetes mellitus (GDM). Random plasma glucose, GGT, ALT and AST and the 50-g glucose challenge test were done on antenatal women followed by diagnostic 3-point 75-g oral glucose tolerance test within two weeks. GDM was diagnosed by ADA (2011) criteria. The GDM rate was 12.2% (319/2610). Mean GGT level was higher in GDM women, 18 ± 12 vs. 16 ± 11 IU/L; P=0.03. The risk for GDM was higher for women in the highest GGT quartile band compared to the lowest: RR 1.35 95%CI 1.0-1.8; P=0.04. However, after adjustment for confounders, GGT was no longer associated with GDM. There was no correlation between ALT and AST levels and GDM.

A meta-analysis was carried out to evaluate the efficacy of yoga in adults with type 2 diabetes mellitus. The PubMed, EMBASE and Cochrane databases were searched to obtain eligible randomized controlled trials. The primary outcome was fasting blood glucose, and the secondary outcomes included glycosylated hemoglobin A1c, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglyceride and postprandial blood glucose. Weighted mean differences and 95% confidence intervals (CIs) were calculated. The I 2 statistic represented heterogeneity. A total of 12 randomized controlled trials with a total of 864 patients met the inclusion criteria. The pooled weighted mean differences were -23.72 mg/dL (95% CI -37.78 to -9.65; P = 0.001; I 2 = 82%) for fasting blood glucose and -0.47% (95% CI -0.87 to -0.07; P = 0.02; I 2 = 82%) for hemoglobin A1c. The weighted mean differences were -17.38 mg/dL (95% CI -27.88 to -6.89; P = 0.001; I 2 = 0%) for postprandial blood glucose, -18.50 mg/dL (95% CI -29.88 to -7.11; P = 0.001; I 2 = 75%) for total cholesterol, 4.30 mg/dL (95% CI 3.25 to 5.36; P < 0.00001; I 2 = 10%) for high-density lipoprotein cholesterol, -12.95 mg/dL (95% CI -18.84 to -7.06; P < 0.0001; I 2 = 37%) for low-density lipoprotein cholesterol and -12.57 mg/dL (95% CI -29.91 to 4.76; P = 0.16; I 2 = 48%) for triglycerides. The available evidence suggests that yoga benefits adult patients with type 2 diabetes mellitus. However, considering the limited methodology and the potential heterogeneity, further studies are necessary to support our findings and investigate the long-term effects of yoga in type 2 diabetes mellitus patients. © 2016 The Authors.

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.

Repaglinide: a review of its therapeutic use in type 2 diabetes mellitus.
Culy, C R; Jarvis, B
2001-01-01
Repaglinide, a carbamoylmethyl benzoic acid derivative, is the first of a new class of oral antidiabetic agents designed to normalise postprandial glucose excursions in patients with type 2 diabetes mellitus. Like the sulphonylureas, repaglinide reduces blood glucose by stimulating insulin release from pancreatic beta-cells, but differs from these and other antidiabetic agents in its structure, binding profile, duration of action and mode of excretion. In clinical trials of up to 1-year's duration, repaglinide maintained or improved glycaemic control in patients with type 2 diabetes mellitus. In comparative, 1-year, double-blind, randomised trials (n = 256 to 544), patients receiving repaglinide (0.5 to 4mg before 3 daily meals) achieved similar glycaemic control to that in patients receiving glibenclamide (glyburide) < or = 15 mg/day and greater control than patients receiving glipizide < or = 15 mg/day. Changes from baseline in glycosylated haemoglobin and fasting blood glucose levels were similar between patients receiving repaglinide and glibenclamide in all studies; however, repaglinide was slightly better than glibenclamide in reducing postprandial blood glucose in I short term study (n = 192). Patients can vary their meal timetable with repaglinide: the glucose-lowering efficacy of repaglinide was similar for patients consuming 2, 3 or 4 meals a day. Repaglinide showed additive effects when used in combination with other oral antidiabetic agents including metformin, troglitazone, rosiglitazone and pioglitazone, and intermediate-acting insulin (NPH) given at bedtime. In 1-year trials, the most common adverse events reported in repaglinide recipients (n = 1,228) were hypoglycaemia (16%), upper respiratory tract infection (10%), rhinitis (7%), bronchitis (6%) and headache (9%). The overall incidence of hypoglycaemia was similar to that recorded in patients receiving glibenclamide, glipizide or gliclazide (n = 597) [18%]; however, the incidence of serious hypoglycaemia appears to be slightly higher in sulphonylurea recipients. Unlike glibenclamide, the risk of hypoglycaemia in patients receiving repaglinide was not increased when a meal was missed in 1 trial. In conclusion, repaglinide is a useful addition to the other currently available treatments for type 2 diabetes mellitus. Preprandial repaglinide has displayed antihyperglycaemic efficacy at least equal to that of various sulphonylureas and is associated with a reduced risk of serious hypoglycaemia. It is well tolerated in a wide range of patients, including the elderly, even if a meal is missed. Furthermore, glycaemic control is improved when repaglinide is used in combination with metformin. Thus, repaglinide should be considered for use in any patient with type 2 diabetes mellitus whose blood glucose cannot be controlled by diet or exercise alone, or as an adjunct in patients whose glucose levels are inadequately controlled on metformin alone.

An association between diabetes mellitus and alterations in the oral cavity has been noted. In this study, we evaluated differences between salivary IgA, glucose and flow rate in diabetic patients compared with healthy controls. Forty patients with type 1 diabetes, 40 patients with type 2 diabetes and 40 healthy controls were selected. Whole unstimulated saliva samples were collected by the standard method and the salivary flow rate was determined. Nephelometric and Pars method were used to measure salivary IgA and salivary glucose concentrations, respectively. Statistical analysis was performed by Chi-square and t test. There were no significant differences in salivary IgA and glucose concentrations between type 1 and type 2 diabetic patients and their matched control subjects (P>0.05). Salivary flow rate was significantly lower in diabetic patients (P<0.05). In addition, DMFT was higher in diabetic patients than the controls. Determination of salivary constituents may be useful in the description and management of oral findings in diabetic patients.

Dental caries-associated risk factors and type 1 diabetes mellitus.
Sampaio, Norma; Mello, Sandra; Alves, Cresio
2011-01-01
Type 1 diabetes mellitus (T1DM) is associated with various oral complications. However there is no consensus regarding the association of T1DM and caries. Critical revision of dental caries-associated risk factors and type 1 diabetes mellitus. Search of the MEDLINE and LILACS databases from 2000 to 2010, using, in different combination, the key words "dental caries", "diabetes mellitus" and "type 1 diabetes mellitus". The association between T1DM and dental caries remains controversial. Although some studies demonstrate a higher prevalence of caries due to the increased concentration of salivary glucose, acidity of the oral cavity, salivary viscosity, reduced salivary flow rate, and salivary gland dysfunction; other studies report a reduction of caries levels, probably caused by decreased ucrose ingestion. Although patients with uncontrolled T1DM and poor oral hygiene may present increased prevalence of dental caries, the literature does not describe a consistent relationship between T1DM and dental caries. Further investigations are warranted. If a true association is substantiated, intervention studies to prevent or reduce the occurrence of caries in this population should follow.

Translational Implications of the β Cell Epigenome in Diabetes Mellitus
Johnson, Justin S.; Evans-Molina, Carmella
2014-01-01
Diabetes mellitus is a disorder of glucose homeostasis that affects over 24 million Americans and 382 million individuals worldwide. Dysregulated insulin secretion from the pancreatic β cells plays a central role in the pathophysiology of all forms of diabetes mellitus. Therefore an enhanced understanding of the pathways that contribute to β cell failure is imperative. Epigenetics refers to heritable changes in DNA transcription that occur in the absence of changes to the linear DNA nucleotide sequence. Recent evidence suggests an expanding role of the β cell epigenome in the regulation of metabolic health. The goal of this review is to discuss maladaptive changes in β cell DNA methylation patterns and chromatin architecture and their contribution to diabetes pathophysiology. Efforts to modulate the β cell epigenome as a means to prevent, diagnose, and treat diabetes will also be discussed. PMID:24686035

Control of glucose homeostasis and insulin sensitivity by the Let-7 family of microRNAs
Frost, Robert J. A.; Olson, Eric N.
2011-01-01
Diabetes mellitus is the most common metabolic disorder worldwide and a major risk factor for cardiovascular disease. MicroRNAs are negative regulators of gene expression that have been implicated in many biological processes, including metabolism. Here we show that the Let-7 family of microRNAs regulates glucose metabolism in multiple organs. Global and pancreas-specific overexpression of Let-7 in mice resulted in impaired glucose tolerance and reduced glucose-induced pancreatic insulin secretion. Mice overexpressing Let-7 also had decreased fat mass and body weight, as well as reduced body size. Global knockdown of the Let-7 family with an antimiR was sufficient to prevent and treat impaired glucose tolerance in mice with diet-induced obesity, at least in part by improving insulin sensitivity in liver and muscle. AntimiR treatment of mice on a high-fat diet also resulted in increased lean and muscle mass, but not increased fat mass, and prevented ectopic fat deposition in the liver. These findings demonstrate that Let-7 regulates multiple aspects of glucose metabolism and suggest antimiR-induced Let-7 knockdown as a potential treatment for type 2 diabetes mellitus. Furthermore, our Cre-inducible Let-7-transgenic mice provide a unique model for studying tissue-specific aspects of body growth and type 2 diabetes. PMID:22160727

Diabetes mellitus presents a significant public health burden based on its increased morbidity, mortality, and economic cost. The high comorbidity and prevalence of concomitant diseases like hypertension and dyslipidemia in diabetic patients cause the high risk in developing secondary, cost intensive, and for the patient often disastrous late complications (nephropathy, retinopathy, neuropathy, and cardiovascular disease). Therefore, patients with diabetes mellitus need a global risk management that takes the various individual clinical problems into account. The current global standards of therapy in patients with diabetes mellitus are focused on the control of glycemia, blood pressure, and lipid levels, as well as aspirin therapy and avoiding of smoking. There are a number of guidelines and recommendations to manage these global issues. Our review will summarize current recommendations and consolidate therapeutic goals and treatments that are of vital importance in the global risk management in diabetic patients.

To investigate the prevalence of impaired fasting glucose (IFG) and total diabetes mellitus (DM) including known diabetes and newly diagnosed diabetes in working age men of North China. A cross-section study was conducted at health medical center of Ansteel Group Hospital in Anshan city of China. 37,345 males between 20-60 years of age were recruited in this study. Age-standardized prevalence of IFG and total DM in these working age men were 25.3% and 8.4%, respectively. The prevalence of IFG and total DM increased, as the age progressed. After multinomial logit analysis, age, systolic blood pressure, drinking, smoking, overweight and obesity, total cholesterol, triglycerides, serum creatinine and blood urea nitrogen were independent risk factors for both IFG and DM. The prevalence rate of IFG in Anshan male workers was higher compared with mainland China overall. Diabetes-related education and popularization of DM prevention programs should be actively carried out with age increasing.

The purpose of this study was to use a low-cost method of estimating prevalence of diabetes mellitus for a small island population receiving medical care from a single facility. A suitable sample of 692 (16.4%) from a total of 4,223 medical records of Ebeye Island Marshallese adult outpatients 30 or more years of age was reviewed in July and August 2000 for evidence of diabetes mellitus. Diagnosed diabetes was defined as having a diagnosis of diabetes noted in the chart. In patients without a diagnosis of diabetes, undiagnosed diabetes was defined as one fasting whole blood glucose > or = 70 mmol/l (126 mg/dl) or one random whole blood glucose > or = 11.1 mmol/l (200 mg/dl). Impaired fasting glucose was defined as one fasting whole blood glucose 6.1-7.0 mmol/l (110-125 mg/dl). For this population of adults 30 or more years in age, the crude prevalence of diabetes [diagnosed cases 13% (confidence interval, CI = 10-15%) and undiagnosed cases 6.9% (CI = 5.0-8.8%)] was 20% (CI = 17-23%). As the population of Ebeye is younger than the world population, adjustment to a standard world population gives an age-adjusted prevalence of diabetes in adults 30 or more years of age of 27%, and an age-adjusted prevalence in adults 20 or more years of age of 20%. In comparison, the crude prevalence of diagnosed and undiagnosed diabetes in the U.S. in adults 20 or more years of age is 8.3%, and the worldwide prevalence in adults 20 or more years of age is 4.0%. Limitations of our methodology include lack of randomization, lack of access to proper laboratory equipment, and passive case-finding, necessitating revision of standard diagnostic criteria. Prevalence rates of diabetes in Marshallese outpatients are thus significantly higher than US or worldwide rates. In addition, there are many cases of undiagnosed diabetes in the RMI. Recommended are a cross-sectional serosurvey of a large age- and gender-stratified population, increased resources to care for people with diabetes, and public health interventions to improve nutrition and facilitate physical activity in order to lower the prevalence of diabetes. The large-scale social forces that lead to diabetes need to be addressed accordingly.

Skeletal muscle, hepatic insulin resistance, and beta cell dysfunction are the characteristic pathophysiological features of type 2 diabetes mellitus. GABA has an important role in pancreatic islet cells. The present study attempted to clarify the possible mechanism of GABA to improve glucose tolerance in a model of type 2 diabetes mellitus in rats. Fifty Wistar rats were divided into five groups: NDC that was fed the normal diet, CD which received a high-fat diet with streptozotocin, CD-GABA animals that received GABA via intraperitoneal injection, plus CD-Ins1 and CD-Ins2 groups which were treated with low and high doses of insulin, respectively. Body weight and blood glucose were measured weekly. Intraperitoneal glucose tolerance test (IPGTT), insulin tolerance test (ITT), urine volume, amount of water drinking, and food intake assessments were performed monthly. The hyperinsulinemic euglycemic clamp was done for assessing insulin resistance. Plasma insulin and glucagon were measured. Abdominal fat was measured. Glucagon receptor, Glucose 6 phosphatase, Phosphoenolpyruvate carboxykinase genes expression were evaluated in liver and Glucose transporter 4 (GLUT4) genes expression and protein translocation were evaluated in the muscle. GABA or insulin therapy improved blood glucose, insulin level, IPGTT, ITT, gluconeogenesis pathway, Glucagon receptor, body weight and body fat in diabetic rats. GLUT4 gene and protein expression increased. GABA whose beneficial effect was comparable to that of insulin, also increased glucose infusion rate during an euglycemic clamp. GABA could improve insulin resistance via rising GLUT4 and also decreasing the gluconeogenesis pathway and Glucagon receptor gene expression. Copyright © 2018. Published by Elsevier B.V.

Vitamins and Type 2 Diabetes Mellitus
Valdés-Ramos, Roxana; Ana Laura, Guadarrama-López; Elina, Martínez-Carrillo Beatriz; Donají, Benítez-Arciniega Alejandra
2015-01-01
The present review evaluates the relationship between type 2 diabetes mellitus and individual or combined vitamins. Antioxidant vitamins A, C and E are found decreased in diabetic subjects, possibly due to an increased need to control the excessive oxidative stress produced by abnormalities in glucose metabolism. On the other hand, retinol binding protein exerts a modulating effect, as it has adipokine functions. With respect to the B group vitamins, thiamin, pyridoxine and biotin have been found decreased but the mechanisms are not clear, however supplementation has shown some improvement of the metabolic control in diabetic patients. The absorption of folic acid and vitamin B12 is importantly decreased by the prolongued use of metformin, which is the first choice drug in uncomplicated diabetes, thus these two nutrients have been found deficient in the disease and most probably need to be supplemented regularly. On the other hand, vitamin D is considered a risk factor for the development of diabetes as well as its complications, particularly cardiovascular ones. Although some studies have found an association of vitamin K intake with glucose metabolism further research is needed. Studies on the use of multivitamin supplements have shown unconclusive results. After reviewing the evidence, no real recommendation on the use of vitamin supplements in type 2 diabetes mellitus can be issued, however patients using metformin during prolongued periods may need folic acid and vitamin B12.

This study was conducted to determine self-care practices and diabetes related emotional distress among people with Type 2 diabetes mellitus in Dar es Salaam, Tanzania. A cross sectional survey-involving 121 Types 2 diabetics was conducted in 4 diabetic clinics located in Dar es Salaam. Anthropometric and biomedical measurements namely weight, height, waist, hip, mid-upper arm circumference, blood pressure and fasting blood glucose were measured. Self-care practices and diabetic related emotion distress were evaluated by using validated instruments. Results revealed that, the average fasting plasma glucose was 11.2 ± 5.5 mmol/l, blood pressure was 134.7/86.1 mm/Hg and the mean BMI for males and females were 25.0 ± 4.3 and 27.0 ± 5.1 kg/m(2), respectively. Subject's self-care score for general diet, specific diet, physical exercise, foot-care and medication were 4.6 ± 2.4, 3.7 ± 1.5, 3.4 ± 1.8, 3.6 ± 2.8 and 5.5 ± 2.8 days per week, respectively. Self-monitoring of blood glucose was irregular and only 46.3% of the subjects tested their levels of blood glucose at least once in between the appointments (90 days). Low income was the major limitation for complying with the self-care practices related to diet, blood glucose testing and medication. It is recommended that, the Government of Tanzania should in the short run subsidize the prices of diabetes drugs, remove all taxes on the glucose test kits and establish a national diabetes program that would coordinate and oversee provision of the basic services such as screening, glucose testing, medication, counseling and management of the condition. In the long run, the government should establish a preventive public health program in order to curtail the escalation of diabetes. Further research should be conducted to determine how factors such as socio-cultural and demographic, self-care, and psychosocial distress interact to determine biomedical outcomes such as blood pressure, blood glucose and body mass index.

We retrospectively investigated the effect of adding dipeptidyl peptidase-4 (DPP-4) inhibitor and tapering sulfonylurea on blood glucose fluctuation in Asian patients with type 2 diabetes mellitus under basal-supported oral therapy (BOT). We recruited twenty-two consecutive Japanese patients with type 2 diabetes mellitus who had blood glucose fluctuation under the combination therapy of insulin glargine and glimepiride and had sitagliptin initiated with glimepiride tapared. Their hemoglobin A1c levels and mean blood glucose profiles of seven points in self-monitoring blood glucose (SMBG) were 7.4 ± 0.6% and 8.6 ± 2.0 mmol/L, respectively. Sitagliptin was initiated with the dose of 50 mg per day and titrated up to 100 mg per day when necessary. Glimepiride was withdrawn if possible. Blood glucose fluctuation was evaluated with SMBG by calculating M-value, its range (the difference of maximum and minimum blood glucose levels), and its coefficient of variation (CV). Two months after sitagliptin add-on, M-value was decreased from 19 ± 13 to 13 ± 8 (p = 0.04). Blood glucose range and CV were also improved from 9.6 ± 2.9 mmol/L to 7.9 ± 2.6 mmol/L (p = 0.01), and from 33 ± 8% to 29 ± 8% (p < 0.01), respectively. Hemoglobin A1c levels and mean blood glucose profiles were unchanged (p = 0.93 and 0.47). In conclusion, blood glucose fluctuation was significantly improved two months after adding sitagliptin and tapering glimepiride in type 2 diabetic Japanese patients who were treated by BOT with insulin glargine and glimepiride.

To determine whether hyperglycemia in IDDM (insulin-dependent diabetes mellitus) could interfere with salivary secretion rates, salivary glucose levels, and salivary microbial counts, we studied salivary factors in two groups of children and adolescents with IDDM. One study group included 14 children with newly diagnosed IDDM )mean age 11 years, SD +/- 2.4 years). Samples of saliva were collected on admission to hospital and after 2 weeks on insulin treatment. The other study group were 50 IDDM children (mean age 14.4 years, SD +/- 1.7 years, mean duration of diabetes 6.2 years, SD +/- 1.4 years) visiting the outpatient diabetic clinic. Samples of saliva were collected during two visits, approximately 3 months apart. In the newly diagnosed IDDM cases, mean salivary glucose level decreased from 54.1 +/- 31.7 mg/l to 35.2 +/- 29.5 mg/l (P = 0.096) after beginning insulin treatment. During hyperglycemia, salivary glucose levels correlated with mean blood glucose levels for the day concerned (r = 0.65, P < 0.05). The results suggest that high blood glucose levels can increase salivary glucose levels. Stimulated saliva secretion increased significantly from 5.4 +/- 3.3 ml/5 min to 7.3 +/- 2.6 ml/5 min (P < 0.01) while glucose balance improved. In the long-term IDDM cases, salivary flow rates and salivary glucose levels were not significantly related to the glycosylated hemoglobin (HbA1) values. Salivary glucose levels and salivary secretion rates were inversely correlated (P < 0.05). In conclusion, hyperglycemia was observed to be associated with decreased salivary secretion and high salivary glucose levels. As a consequence, salivary lactobacilli and yeast counts tended to increase.

Population surveys of Type 2 diabetes mellitus and obesity conducted in Samoa over three decades have used varying methodologies and definitions. This study standardizes measures, and trends of Type 2 diabetes mellitus and obesity for 1978-2013 are projected to 2020 for adults aged 25-64 years. Unit records from eight surveys (n = 12 516) were adjusted to the previous census for Division of residence, sex and age to improve national representativeness. Type 2 diabetes mellitus is defined as a fasting plasma glucose ≥ 7.0 mmol/l and/or on medication. Obesity is defined as BMI ≥ 30 kg/m 2 . Random effects meta-regression was employed to assess time trends following logit transformation. Poisson regression from strata was used to assess the effects of mean BMI changes on Type 2 diabetes mellitus period trends. Over 1978-2013, Type 2 diabetes mellitus prevalence increased from 1.2% to 19.6% in men (2.3% per 5 years), and from 2.2% to 19.5% in women (2.2% per 5 years). Obesity prevalence increased from 27.7% to 53.1% in men (3.6% per 5 years) and from 44.4% to 76.7% (4.5% per 5 years) in women. Type 2 diabetes mellitus and obesity prevalences increased in all age groups. From period trends, Type 2 diabetes mellitus prevalence in 2020 is projected to be 26% in men and women. Projected obesity prevalence is projected to be 59% in men and 81% in women. Type 2 diabetes mellitus period trends attributable to BMI increase are estimated as 31% (men) and 16% (women), after adjusting for age. This is the first study to produce trends of Type 2 diabetes mellitus and obesity in Samoa based on standardized data from population surveys. Type 2 diabetes mellitus is equally prevalent in both sexes, and obesity is widespread. Type 2 diabetes mellitus prevalence in Samoa is likely to continue to increase in the near future. © 2016 The Authors. Diabetic Medicine published by John Wiley & Sons Ltd on behalf of Diabetes UK.

The extraskeletal effects of vitamin D have attracted considerable interest. Vitamin D deficiency appears to be related to the development of diabetes mellitus type 2 and the metabolic syndrome. Vitamin D may affect glucose homeostasis, vitamin D levels having been found to be inversely related to glycosylated hemoglobin levels in gestational diabetes mellitus. In addition, vitamin D appears to protect from the development of gestational diabetes mellitus. The aim was to study levels of 25-hydroxy vitamin D3 [25(OH)D3] and the relationship between 25(OH)D3 levels and glycemic control in patients with diabetes mellitus type 2. Glycosylated hemoglobin (HbA1c) and 25(OH)D3 levels were measured in a group of 120 diabetes mellitus type 2 patients. The same measurements were performed in a group of 120 control subjects of the same age and sex. 25(OH)D3 was measured by radioimmunoassay and glycosylated hemoglobin (HbA1c) was measured by high-performance liquid chromatography. 25(OH)D3 levels were lower in the diabetes mellitus type 2 patients than in the control group, being 19.26 ± 0.95 ng/ml and 25.49 ± 1.02 ng/ml, in the patient and control groups, respectively (p < 0.001, Student's t-test). 25(OH)D3 levels were found to be inversely associated with HbA1c levels in the diabetic patients (p = 0.008, r (2) = 0.058, linear regression). 25(OH)D3 levels were found to be inversely associated with HbA1c when the patient and control groups were analysed together (p < 0.001, r (2) = 0.086). Vitamin D levels appeared to be lower in diabetes mellitus type 2 patients than in the control group, vitamin D levels being related to glycemic control in diabetes mellitus type 2. These findings may have therapeutic implications as cautious vitamin D supplementation may improve glycemic control in diabetes mellitus type 2.

Previous studies have demonstrated that elevated admission and fasting glucose (FG) is associated with worse outcomes in patients with acute myocardial infarction (AMI). However, the quantitative relationship between FG levels and in-hospital mortality in patients with AMI remains unknown. The aim of the study is to assess the prevalence of elevated FG levels in hospitalized Chinese patients with AMI and diabetes mellitus and to determine the quantitative relationship between FG levels and the in-hospital mortality as well as the optimal level of FG in patients with AMI and diabetes mellitus. A retrospective study was carried out in 1856 consecutive patients admitted for AMI and diabetes mellitus from 2002 to 2013. Clinical variables of baseline characteristics, in-hospital management and in-hospital adverse outcomes were recorded and compared among patients with different FG levels. Among all patients recruited, 993 patients (53.5 %) were found to have FG ≥100 mg/dL who exhibited a higher in-hospital mortality than those with FG < 100 mg/dL (P < 0.001). Although there was a high correlation between FG levels and in-hospital mortality in all patients (r = 0.830, P < 0.001), the relationship showed a J-curve configuration with an elevated mortality when FG was less than 80 mg/dL. Using multivariate logistic regression models, we identified that age, FG levels and Killip class of cardiac function were independent predictors of in-hospital mortality in AMI patients with diabetes mellitus. More than half of patients with AMI and diabetes mellitus have FG ≥100 mg/dL and the relationship between in-hospital mortality and FG level was a J-curve configuration. Both FG ≥ 100 mg/dL and FG <80 mg/dL were identified to be independent predictors of in-hospital mortality and thus the optimal FG level in AMI patients with diabetes mellitus appears to be 80-100 mg/dL.

To determine the effectiveness of an electronic messaging support service for management of cardiovascular risk factors in patients with diabetes. Microletter and short message service are widely used, but their health education benefit for people with type 2 diabetes mellitus has not been investigated. Convenience sample study with randomised group assignment. Participants completed survey questionnaires, physical and laboratory evaluations between May 2015 and May 2016 and were then randomly assigned to two groups for receipt of a microletter + short message or a phone call (control). Appointment reminders and health information were sent to the intervention patients by microletter + short message. Every three months, intervention patients and control patients were followed up by telephone. After 12 months, changes in cardiovascular risk factors in each group were evaluated and compared. There were no statistically significant changes or between-group differences in daily smoking and drinking. There were statistically significant between-group differences in glycated haemoglobin (p = .034), postprandial plasma glucose (p = .001), postprandial insulin (p = .005), total cholesterol (p = .038) and low-density lipoprotein (p < .001). Levels of glycated haemoglobin (p = .011), fasting plasma glucose (p = .007), postprandial plasma glucose (p < .001), fasting insulin (p = 0.004), postprandial insulin (p < .001), total cholesterol (p < .001) and low-density lipoprotein (p < .001) were found to be decreased significantly in intervention patients. Systolic blood pressure decreased significantly in patients only followed by telephone (p = .014). The microletter + short message intervention was an effective means of reducing cardiovascular risk in patients with type 2 diabetes mellitus. Regular smartphone communication had a favourable impact on cardiovascular risk factors in patients with type 2 diabetes mellitus.

Diabetes mellitus is a debilitating hormonal disorder in which strict glycemic control and prevention of associated complications are of crucial importance. This study was designed to evaluate the hypoglycemic effect of methanolic extract of mature, green fruits of Musa paradisiaca (MEMP) in normal (normoglycemic) and streptozotocin (STZ)-treated, diabetic (hyperglycemic) mice, using chlorpropamide as the reference antidiabetic agent. MEMP (100-800 mg/kg p.o.) induced significant, dose-related (p < 0.05-0.001) reductions in the blood glucose concentrations of both normal and diabetic mice. Chlorpropamide (250 mg/kg p.o.) also produced significant (p < 0.01-0.001) reductions in the blood glucose concentrations of normal and diabetic mice. The results of this experimental study indicate that, in the mammalian model used, MEMP possesses hypoglycemic activity. Although the precise mechanism of the hypoglycemic action of MEMP is still unclear and will have to await further studies, it could be due, at least in part, to stimulation of insulin production and subsequent glucose utilization. Nevertheless, the findings of this experimental animal study indicate that MEMP possesses hypoglycemic activity, and thus lends credence to the suggested folkloric use of the plant in the management and/or control of adult-onset, type-2 diabetic mellitus among the Yoruba-speaking people of South-Western Nigeria.

Due to substantial morbidity and high complications, diabetes mellitus is considered as the third “killer” in the world. A search for alternative antidiabetic drugs from herbs or fungi is highly demanded. Our present study aims to investigate the antidiabetic activities of Cordyceps militaris on diet-streptozotocin-induced type 2 diabetes mellitus in rats. Diabetic rats were orally administered with water extract or alcohol extract at 0.05 g/kg and 2 g/kg for 3 weeks, and then, the factors levels related to blood glucose, lipid, free radicals, and even nephropathy were determined. Pathological alterations on liver and kidney were examined. Data showed that, similar to metformin, Cordyceps militaris extracts displayed a significant reduction in blood glucose levels by promoting glucose metabolism and strongly suppressed total cholesterol and triglycerides concentration in serum. Cordyceps militaris extracts exhibit antioxidative effects indicated by normalized superoxide dismutase and glutathione peroxidase levels. The inhibitory effects on blood urea nitrogen, creatinine, uric acid, and protein revealed the protection of Cordyceps militaris extracts against diabetic nephropathy, which was confirmed by pathological morphology reversion. Collectively, Cordyceps militaris extract, a safe pharmaceutical agent, presents excellent antidiabetic and antinephropathic activities and thus has great potential as a new source for diabetes treatment.

Diabetes mellitus is a complex metabolic disorder characterized by chronic hyperglycemia, and associated with long-term damage and dysfunction of various organs. Management of diabetes is therefore vital and involves maintaining euglycemia as much as possible by reducing blood glucose and by increasing insulin sensitivity and peripheral glucose uptake. Ayurveda has promoted the management of diabetes by regulating carbohydrate metabolism using several medicinal herbs, one of which is Gymnema sylvestre (GS). GS has been used in parts of India as a hypoglycemic agent and the results have been encouraging. Accordingly, we planned a quasi-experimental study to investigate the efficacy of the herb among type 2 diabetics. Patients enrolled from free-living population were purposively assigned to experimental or control groups, based on their willingness to participate in the study. The experimental group was supplemented with 500 mg of the herb per day for a period of 3 months, and the efficacy of the herb was assessed through a battery of clinical and biochemical tests. Supplementation of the diet with GS reduced polyphagia, fatigue, blood glucose (fasting and post-prandial), and glycated hemoglobin and there was a favorable shift in lipid profiles and in other clinico-biochemical tests. These findings suggest a beneficial effect of GS in the management of diabetes mellitus.

The function of endothelial progenitor cells (EPCs), which are key cells in vascular repair, is impaired in diabetes mellitus. Nitric oxide (NO) and reactive oxygen species can regulate EPC functions. EPCs tolerate oxidative stress by upregulating superoxide dismutase (SOD), the enzyme that neutralizes superoxide anion (O2-). Therefore, we investigated the roles of NO and SOD in glucose-stressed EPCs. The functions of circulating EPCs from patients with type 2 diabetes were compared to those from healthy individuals. Healthy EPCs were glucose-stressed, and then treated with insulin and/or SOD. We assessed O2- generation, NO production, SOD activity, and their ability to form colonies. EPCs from diabetic patients generated more O2-, had higher NAD(P)H oxidase and SOD activity, but lower NO bioavailability, and expressed higher mRNA and protein levels of p22-phox, and manganese SOD and copper/zinc SOD than those from the healthy individuals. Plasma glucose and HbA1c levels in the diabetic patients were correlated negatively with the NO production from their EPCs. SOD treatment of glucose-stressed EPCs attenuated O2- generation, restored NO production, and partially restored their ability to form colonies. Insulin treatment of glucose-stressed EPCs increased NO production, but did not change O2- generation and their ability to form colonies. However, their ability to produce NO and to form colonies was fully restored after combined SOD and insulin treatment. Our data provide evidence that SOD may play an essential role in EPCs, and emphasize the important role of antioxidant therapy in type 2 diabetic patients.

An increase in macular thickness due to fluid accumulation in the macula in patients with diabetes mellitus. Optical coherence tomography (OCT) has been shown to be highly reproducible in measuring macular thickness in normal individuals and diabetic patients. OCT can detect subtle changes of macular thickness. The aim of this study is to compare central macular thickness (CMT) of diabetic patients with type 2 diabetes without clinical retinopathy and normal controls, in order to assess possible increased macular thickness associated with diabetes mellitus. Optical coherence tomography (OCT) measurements were performed in 124 eyes of 62 subjects with diabetes mellitus without clinically retinopathy (study group: 39 female, 23 male, mean age: 55.06 ± 9.77 years) and in 120 eyes of 60 healthy subjects (control group: 35 female, 25 male, mean age: 55.78 ± 10.34 years). Blood biochemistry parameters were analyzed in all cases. The data for central macular thickness (at 1 mm) and the levels of the fasting plasma glucose and glycosylated hemoglobin (HbA1c) were compared in both groups. The mean central macular thickness was 232.12 ±24.41 μm in the study group and 227.19 ± 29.94 μm in the control group.The mean HbA1c level was 8.92 ± 2.58% in the study group and 5.07 ± 0.70% in the control group (p=0.001). No statistically significant relationship was found between CMT, HbA1c, and fasting plasma glucose level in either group (p=0.05). Central macular thickness was not significantly thicker in patients with type 2 diabetes without clinical retinopathy than in healthy subjects.

Latent autoimmune diabetes in adults (LADA) represents a subgroup of diabetes mellitus. LADA is characterised by adult-onset diabetes and circulating autoimmune antibodies. LADA patients may need a different therapeutic approach than the usual type 2 diabetes mellitus. When LADA is inadequately diagnosed as type 2 diabetes mellitus, LADA patients will mistakenly be exposed to a high dose of oral glucose lowering drugs and their possible side effects. To assess which clinical features predict the presence or absence of LADA in patients older than 25 years presenting with hyperglycemia. A structured Medline and Embase search was conducted. Titles and abstracts were screened using predetermined selection criteria. Critical appraisal was based on standardized validity criteria for diagnostic research. One-hundred and eighty-four papers were retrieved of which after assessment of relevance and validity 2 studies remained for further analysis. One study reported a probability of LADA of 0.99 with one or two out of the following five clinical features: age at onset <50 years; acute symptoms; BMI<25 kg/m(2); a history of autoimmune disease; a family history positive for diabetes mellitus. The other study reported a probability of LADA of zero with none of the following clinical features and of 0.32 with one out of three: fasting blood glucose> or =15 mmol/l and/or HbA(1c)> or =10%; 10% reduction in body weight in the previous 3 months; BMI<25 kg/m(2). Further testing for LADA by measurement of autoimmune antibodies appears to be unnecessary in the absence of a specific set of clinical features. Before initiating therapy applying the above criteria may help to separate LADA from usual type 2 diabetes.

Various strategies have been adopted to combat complications caused by Type 2 diabetes mellitus and controlled diet is one of them. Monoterpenes, major constituents of essential oils, are synthesized and widely used as artificial food flavors. A series of twelve monoterpenes were assessed in the present study. Monoterpenes, exhibited low 2,2-diphenyl-2-picrylhydrazyl hydrate (DPPH) and 2,2'-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical scavenging activity even at high concentrations. Some monoterpenes inhibited α-amylase and α-glucosidase activity and stimulated glucose uptake and lipolysis. Monoterpenes such as (R)-(+)-limonene stimulated both glucose uptake (17.4%) and lipolysis (17.7%); the mRNA expression of glucose transporter 1 (GLUT1) was upregulated but glucose transporter 4 (GLUT4) was unaffected, and adipose triglyceride lipase (ATGL) was suppressed. Taken together, the selected monoterpenes may not confer strong protection against free radicals but nevertheless, their positive influence on lipid and glucose metabolism may have potential in the control of obesity and Type 2 diabetes mellitus.

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 < 0.05), whereas rs2576178 showed weak association (p = 0.030) that was lost after multiple adjustments (p = 0.09). We inferred a modest association of the rs10887800 polymorphism with 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.

Trelagliptin, a novel once-weekly oral dipeptidyl peptidase-4 (DPP-4) inhibitor, has shown favorable efficacy and safety in type 2 diabetes mellitus patients. Trelagliptin was launched in Japan, and is expected to be initially used for switchover from a daily DPP-4 inhibitor in the clinical setting. Thus, the present study was carried out to explore the efficacy and safety of trelagliptin after a daily DPP-4 inhibitor was switched to it. This was an open-label, phase 3 exploratory study to evaluate the efficacy and safety of trelagliptin in Japanese type 2 diabetes mellitus patients who had stable glycemic control on once-daily sitagliptin therapy. Eligible patients received trelagliptin 100 mg orally before breakfast once a week for 12 weeks. The primary end-point was blood glucose by the meal tolerance test, and additional end-points were glycemic control (efficacy) and safety. Altogether, 14 patients received the study drug. The blood glucose did not markedly change from baseline at major assessment points in the meal tolerance test, and a decrease in blood glucose was observed at several other assessment points. Adverse events were reported in 42.9% (6/14) of patients, but all adverse events were mild or moderate in severity, and most were not related to the study drug. No cases of death, serious adverse events or hypoglycemia were reported. It is considered possible to switch a once-daily DPP-4 inhibitor to trelagliptin in type 2 diabetes mellitus patients with stable glycemic control in combination with diet and exercise therapy without any major influences on glycemic control or safety. © 2017 The Authors.

Diabetes mellitus (DM) can present complications of neuropathy and peripheral arterial disease with high risk for developing foot ulcers and consequent amputations. To identify the association between peripheral vascular disease, and neuropathy in type 2 Diabetes mellitus patients from the Hospital General de Zona No. 1 IMSS in Colima, Mexico. Cross-sectional study of 80 patients with diabetes mellitus evaluated by means of the Edinburgh Claudication Questionnaire, Michigan Neuropathy Screening Instrument, ankle-arm index, Motor Nerve Conduction Velocity and H-reflex. 51 women and 29 men were studied. Mean age was 53.9 +/- 9.6 years, mean diabetes mellitus progression was 8 +/- 6.6 years and mean glucose level was 283 +/- 110 mg/mL. Neuropathy presented in 65 patients (81.2%). Ankle/arm index revealed 19% of patients presented with moderate peripheral vascular insufficiency. Motor Nerve Conduction Velocity was abnormal in 40% of patients and H-reflex was absent in 70%. Grade 2 motor-sensitive polyneuropathy was found in 70-80% of patients and moderate peripheral vascular insufficiency in 19%. It can thus be inferred that the complication of diabetic neuropathy appears before that of peripheral vessel damage.

The objective of this study was to determine whether improvements in the level of diabetic control in a group of subjects with poorly controlled non-insulin-dependent diabetes mellitus influence salivary output and composition. Repeated whole unstimulated and stimulated parotid saliva samples were collected from diabetic patients attending an outpatient diabetes education program and a matched nondiabetic control group. Saliva was analyzed for flow rates, parotid protein concentration and composition, and amylase activity. Subjective responses to questions about salivary hypofunction were tested. There were no significant differences in whole unstimulated and stimulated parotid flow rates or stimulated parotid protein concentration and composition between diabetics and the control group. Amylase activity was higher in diabetics and decreased with improved glycemic control. Subjects reporting taste alterations had higher mean blood glucose levels than subjects with normal taste sensation. Poorly controlled non-insulin-dependent diabetes mellitus has no influence on saliva output, although amylase activity may be elevated, and there may be taste alterations.

Background: Previous studies of Citrus spp. peel have shown hypoglycemic and antioxidant activities. Citrus limetta has been studied for its therapeutic properties. Diabetes mellitus (DM) is a health problem in Mexico and worldwide, that takes a vital importance due to its high incidence. Recently, scientists have searched natural sources to control the disease. Materials and Methods: In this study, we evaluated the in vitro hypoglycemic activity and in vivo postprandial glycemic effect of C. limetta peel flour by glucose adsorption and retardation assays as well as postprandial serum glucose levels using a group of female Balb-c mice, respectively. Results: C. limetta peel flour showed a glucose adsorption capacity of 16.58 mM, having a similar effect regarding the positive control. The glucose diffusion in the dialysate was elevated, with a glucose dialysis retardation index of 33.79% in a period of 3 h, showing similar results to positive control. Postprandial serum glucose levels in the animal group treated with C. limetta peel flour showed a glucose level of 41.4 mg/dL, being this value significantly lower than negative control group and similar to positive control. Toxicity tests showed good tolerance to the dose of 2000 mg/kg. Conclusion: C. limetta peel flour could act as a source of functional compounds for the control of DM. SUMMARY Citrus limetta peel flour showed a glucose adsorption capacity similar to the positive controlThe glucose diffusion in the dialysate was elevated, showing similar results to positive controlPostprandial serum glucose levels in the animal group treated with C. limetta peel flour showed a glucose level significantly lower than negative control group and similar to positive controlToxicity tests showed good toleranceC. limetta peel flour could act as a source of functional compounds for the control of diabetes mellitus.

Background A study with the yellow passion fruit peel flour showed positive action in blood glucose control as therapies’ adjuvant in patients with type 2 diabetes mellitus. Therefore, we evaluated its effect on insulin sensitivity since there is a quest for studies that focus at better understanding of insulin resistance aspects in diabetic patients. Furthermore its relationship with chronic complications can also give good prospects for alternative treatments. Methods A total of 43 type 2 diabetes volunteers (28 females and 15 males) ingested 30 g/day of the yellow passion fruit peel flour for two months. The levels of blood glucose and fasting insulin, HOMA index and glycated hemoglobin were measured for each patient before and after dietary supplementation. Results There was a significant difference in the fasting blood glucose values (P = 0.000) and glycated hemoglobin (P = 0.032) after supplementation. It was also seen a reduction in HOMA IR (P = 0.005) in the supplemented group, however it was not observed changes in insulin values for females. HOMA beta (P = 0.000) showed significant increase in its values for the studied group. Conclusions The supplementation used decreased insulin resistance in type 2 diabetic patients, suggesting a positive action in blood glucose control as adjuvant therapy in conventional treatments.

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. 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. 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. 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.

Impaired regulation of blood glucose levels in diabetes mellitus (DM) patients and the associated elevation of blood glucose levels are known to increase the risk of diabetic cardiomyopathy (DC). In the present study, a probiotic bacterium, Lactobacillus reuteri GMN-32, was evaluated for its potential to reduce blood glucose levels and to provide protection against DC risks in streptozotocin (STZ)-induced DM rats. The blood glucose levels of the STZ-induced DM rats when treated with L. reuteri GMN-32 decreased from 4480 to 3620 mg/l (with 10⁷ colony-forming units (cfu)/d) and 3040 mg/l (with 10⁹ cfu/d). Probiotic treatment also reduced the changes in the heart caused by the effects of DM. Furthermore, the Fas/Fas-associated protein with death domain pathway-induced caspase 8-mediated apoptosis that was observed in the cardiomyocytes of the STZ-induced DM rats was also found to be controlled in the probiotic-treated rats. The results highlight that L. reuteri GMN-32 treatment reduces blood glucose levels, inhibits caspase 8-mediated apoptosis and promotes cardiac function in DM rats as observed from their ejection fraction and fractional shortening values. In conclusion, the administration of L. reuteri GMN-32 probiotics can regulate blood glucose levels, protect cardiomyocytes and prevent DC in DM rats.

The islets of Langerhans are scattered throughout the pancreas and play a major role in the control of metabolic fuel homeostasis. To get a better understanding of the mechanisms underlying type 1 diabetes mellitus, we have generated a mouse model by injections of multiple low-dose streptozotocin. The islets in the mouse pancreas were handpicked and proteins from the islets were then isolated and separated by two-dimensional gel electrophoresis. Seven proteins were found to be altered significantly at expression level. Among the seven proteins, four were up-regulated and three were down-regulated in diabetic mice as compared with controls. These proteins were successfully identified by matrix-assisted laser desorption/ionization-time of flight mass spectrometry and the changes of selected protein expression were further validated by quantitative real time PCR and Western blotting. Voltage-dependent anion-selective channel protein 1 and peroxiredoxin-4 were found for the first time to be associated with type 1 diabetes mellitus in mouse islets in the current study. These results suggest that glucose transport, beta cell proliferation/death, and oxidative stress play important roles in maintaining the balance of glucose level. Our study also provides novel insight into the mechanism of type 1 diabetes mellitus.

The objective of the study was to compare the modification of fasting blood glucose in adults with diabetes mellitus type 2 after intake of regular soda and diet soda. We conducted a randomized clinical trial in clinics of Instituto Mexicano del Seguro Social in Querétaro, México. We included 80 patients with diabetes (mean weight 74.2 +/- 13.66, BMI 30.5 +/- 4.305, waist 98.2 +/- 12.9 and time evolution of diabetes 3.8 +/- 3.009) who were asked to come with fasting for 8 hours and without taking any medicine before testing. They were divided into two groups of 40 subjects, to whom was measured fasting blood glucose after the ingestion of 200 ml of diet soda (with aspartame and acesulfame potassium) or regular soda (without sweetener) we measure glucose at 10, 15 and 30 minutes. For statistical analysis performed we used Student's t-test for dependent and independent samples, and paired t-test, and chi square test (chi2). Capillary glucose levels at 10 minutes were -34.52 and -25.41%, at 15 minutes -48.8 and -36.2% and at 30 minutes 57.75 and 43.6% of absolute and relative differences, with p = 0.000. In conclusion, according to the observations, diet soda doesn't increased blood glucose levels, with a significant difference in fasting decreased at 30 minutes.

Self-monitoring of blood glucose is the standard of care in management of hyperglycemia among patients with diabetes mellitus. To increase the sensitivity and specificity of current devices, a novel method of detecting glucose using electrochemical impedance spectroscopy (EIS) technology is explored. The enzyme glucose oxidase (GOx) was fixed to gold electrodes and a sine wave of sweeping frequencies was induced using a wide range of concentrations of glucose. Each frequency in the impedance sweep was analyzed for the highest response and R-squared value. The frequency with both factors optimized is specific for the glucose-GOx binding interaction and was determined to be 1.17 kHz in purified solutions in both higher and lower ranges of glucose. The correlation between the impedance response and concentration at the low range of detection (0-100 mg dL(-1) of glucose) was determined to be 3.53 ohm/ln (mg dL(-1)) with an R-squared value of 0.90 with a 39 mg dL(-1) lower limit of detection. The same frequency of 1.17 kHz was verified in whole blood under the same glucose range. The above data confirm that EIS offers a new method of glucose detection as an alternative to current technology in use by patients. Additionally, the unique frequency response of individual markers allows for modulation of signals so that several other markers important in the management of diabetes could be measured with a single sensor.

To investigate dynamic changes in plantar pressure in Chinese diabetes mellitus patients and to provide a basis for further preventing diabetic foot. This is a cross-sectional investigation including 649 Chinese diabetes mellitus patients (diabetes group) and 808 "normal" Chinese persons (nondiabetes group) with normal blood glucose levels. All the subjects provided a complete medical history and underwent a physical examination and a 75-g oral glucose tolerance test. All subjects walked barefoot with their usual gait, and their dynamic plantar forces were measured using the one-step method with a plantar pressure measurement instrument; 5 measurements were performed for each foot. No significant differences were found in age, height, body weight, or body mass index between the two groups. The fasting blood glucose levels, plantar contact time, maximum force, pressure-time integrals and force-time integrals in the diabetes group were significantly higher than those in the nondiabetes group (p < 0.05). However, the maximum pressure was significantly higher in the nondiabetes group than in the diabetes group (p < 0.05). No difference was found in the contact areas between the two groups (p > 0.05). The maximum plantar force distributions were essentially the same, with the highest force found for the medial heel, followed by the medial forefoot and the first toe. The peak plantar pressure was located at the medial forefoot for the nondiabetes group and at the hallucis for the diabetes group. In the diabetes group, the momentum in each plantar region was higher than that in the nondiabetes group; this difference was especially apparent in the heel, the lateral forefoot and the hallucis. The dynamic plantar pressures in diabetic patients differ from those in nondiabetic people with increased maximum force and pressure, a different distribution pattern and significantly increased momentum, which may lead to the formation of foot ulcers. © 2015 by the Wound Healing Society.

Gestational diabetes mellitus (GDM) occurs in 5-15% of pregnancies, and lower maternal educational attainment has been associated with higher risk of GDM. We aimed to determine if maternal education level is associated with persistent post-partum glucose metabolism disorders in women with GDM. Retrospective cohort study of women with GDM followed in 25 Portuguese health institutions between 2008 and 2012. Educational attainment was categorised into four levels. Prevalence of post-partum glucose metabolism disorders (type 2 diabetes mellitus, increased fasting plasma glucose or impaired glucose tolerance) was compared and adjusted odds ratios calculated controlling for confounders using logistic regression. We included 4490 women diagnosed with GDM. Educational level ranged as follows: 6.8% (n = 307) were at level 1 (≤ 6th grade), 34.6% (n = 1554) at level 2 (6-9th grade), 30.4% (n = 1364) at level 3 (10-12th grade) and 28.2% (n = 1265) at level 4 (≥ university degree). At 6 weeks post-partum re-evaluation, 10.9% (n = 491) had persistent glucose metabolism disorders. Educational levels 1 and 2 had a higher probability of persistent post-partum glucose metabolism disorders when compared to level 4 (OR = 2.37 [1.69;3.32], p < 0.001 and OR = 1.39 [1.09;1.76], p = 0.008, for level 1 and 2, respectively), an association that persisted in multivariable logistic regression adjusting for confounders (level 1 OR = 2.25 [1.53;3.33], p < 0.001; level 2 OR = 1.43 [1.09;1.89], p = 0.01). Persistent post-partum glucose metabolism disorders are frequent in women with GDM and associated with lower maternal educational level. Interventions aimed at this risk group may contribute towards a decrease in prevalence of post-partum glucose metabolism disorders.

Bank voles (Clethrionomys glareolus) kept in captivity develop diabetes mellitus to a significant extent. Also in wild bank voles, elevated blood glucose has been observed. A newly isolated picornavirus named Ljungan virus (LV) has been found in the pancreas of these bank voles. Moreover, LV infection in combination with environmental factors may cause glucose intolerance/diabetes (GINT/D) in normal mice. The aim of the present study was to investigate the functional characteristics of pancreatic islets, isolated from bank voles, bred in the laboratory but considered LV infected. About 20% of all males and females were classified as GINT/D following a glucose tolerance test. Of these animals the majority had become diabetic by 20 weeks of age, with a tendency towards an earlier onset in the males. GINT/D animals had increased serum insulin levels. Islets were tested on the day of isolation (day 0) and after 1 week of culture for their insulin content and their capacity to synthesize (pro)insulin, secrete insulin and metabolize glucose. Functional differences could be observed between normal and GINT/D animals as well as between genders. An elevated basal insulin secretion was observed on day 0 indicating beta-cell dysfunction among islets isolated from diabetic males. In vitro culture could reverse some functional changes. The increased serum insulin level and the increased basal islet insulin secretion may suggest that the animals had developed a type 2 diabetes-like condition. It is likely that the putative stress imposed in the laboratory, maybe in combination with LV infection, can lead to an increased functional demand on the beta-cells.

Abnormalities in glucose homeostasis have been described in patients with primary aldosteronism (PA) but most studies show inconsistent results. Therefore, we aimed to compare the prevalence of type 2 diabetes mellitus and metabolic syndrome (MetS) in newly diagnosed PA patients to a matched control cohort of the background population. In total, 305 PA patients of the prospective German Conn's Registry were compared to the population-based Study of Health In Pomerania (SHIP1; n=2454). A 1:1 match regarding sex, age, and BMI resulted in 269 matched pairs regarding type 2 diabetes and 183 matched pairs regarding MetS. Of the total, 153 PA patients underwent oral glucose tolerance testing (OGTT) at diagnosis and 38 PA patients were reevaluated at follow-up. Type 2 diabetes and MetS were significantly more frequent in PA patients than in the control population (17.2% vs 10.4%, P=0.03; 56.8% vs 44.8%, P=0.02 respectively). Also, HbA1c levels were higher in PA patients than in controls (P<0.01). Of the total, 35.3% of non-diabetic PA patients showed an abnormal OGTT (¼ newly diagnosed type 2 diabetes and ¾ impaired glucose tolerance). PA patients with an abnormal OGTT at baseline presented with significantly improved 2 h OGTT glucose (P=0.01) at follow-up. We detected a negative correlation between 2 h OGTT glucose levels and serum potassium (P<0.01). Type 2 diabetes and MetS are more prevalent in patients with PA than in controls matched for sex, age, BMI, and blood pressure. This may explain in part the increased cardiovascular disease morbidity and mortality in PA patients. © 2015 European Society of Endocrinology.

We analysed fasting blood glucose (FBG) and other data collected as part of a population-based nationwide non-communicable disease risk factor survey, to estimate the prevalence of impaired fasting glycaemia (IFG) and diabetes mellitus and to identify associated factors in Uganda. The nationwide cross-sectional survey was conducted between April and July 2014. Participants were adults aged 18-69 years. A multistage stratified sample design was used to produce a national representative sample. Fasting capillary glucose was measured to estimate glycaemia. Data were managed with WHO e-STEPs software and Epi Info. Stata(®) survey procedures were used to account for the sampling design, and sampling weights were used to account for differential probability of selection between strata. Of the 3689 participants, 1467 (39.8%) were males, and 2713 (73.5%) resided in the rural areas. The mean age was 35.1 years (standard deviation = 12.6) for males and 35.8 years (13.2) for females. The overall prevalence of IFG was 2.0% (95% confidence interval (CI) = 1.5-2.5%), whereas that of diabetes mellitus was 1.4% (95% CI 0.9-1.9%). The prevalence of IFG was 2.1% (95% CI 1.3-2.9%) among males and 1.9% (95% CI 1.3-2.6%) among females, whereas that of diabetes mellitus was 1.6% (95% CI 0.8-2.6%) and 1.1% (95% CI 0.6-1.7%), respectively. The prevalence of IFG was 2.6% (95% CI 1.4-3.8%) among urban and 1.9% (95% CI 1.3-2.4%) among rural residents, whereas that of diabetes mellitus was 2.7% (95% CI 1.4-4.1) and 1.0% (95% 0.5-1.6%), respectively. The majority of participants identified with hyperglycaemia (90.5% IFG and 48.9% diabetes) were not aware of their hyperglycaemic status. Factors associated with IFG were region of residence, body mass index and total cholesterol; factors associated with diabetes mellitus were age, sex, household floor finish and abdominal obesity. The prevalence of IFG and of diabetes mellitus is low in the Ugandan population, providing an opportunity for the prevention of diabetes. The majority of persons with hyperglycaemia were not aware of their hyperglycaemic status, which implies a likelihood of presenting late with complications. © 2016 John Wiley & Sons Ltd.

The aim of the present paper was to investigate the effects and possible mechanisms of the total saponins from Dioscorea nipponica Makino (TSDN) against type 2 diabetes mellitus. Streptozotocin (STZ) with high-fat diet induced type 2 diabetes mellitus (T2DM) rats were treated with TSDN. Some biochemical parameters, target proteins and genes were investigated. The results showed that TSDN decreased the levels of food/water intake, fasting blood glucose and serum lipid parameters, ameliorated oral glucose and insulin tolerance test levels, markedly increased body weight and serum insulin, reduced excess free radicals and affected ossification and renal protection. Histopathological examination indicated that TSDN increased liver glycogen, decreased the production of lipid vacuoles and lightened liver damage. Further investigation showed that TSDN down-regulated the protein expressions of NF-κB, GRP78, ATF6, eIF2 and the levels of MAPK phosphorylation and up-regulated the protein expressions of IRS-1, GLUT-4, p-Akt and p-AMPK. In addition, TSDN obviously decreased the gene expressions of TNF-a, IL-6, PEPCK, G6Pase, GSK-3β and GSK-3β activity, and increased the gene expressions of PFK, PK and GK activity. These findings show the anti-diabetic activity of total saponins from D. nipponica Makino, which should be developed as a new potent drug for treatment of diabetes mellitus in future.

Diabetes mellitus (DM) is a group of metabolic disorders of carbohydrate metabolism in which glucose is underutilized, resulting in hyperglycemia. Reproductive impairment in poorly controlled diabetes mellitus type 1 (T1DM) results from a combined effect of insulin deficiency and hyperglycemia that disrupt the functioning of metabolic signals participating in the regulation of the reproductive system. Good metabolic control as a result of intensive insulin therapy has a great impact on the fertility and childbearing possibilities in the T1DM females. Advanced glycation end products (AGEs) are formed by nonenzymatic modification of proteins, lipids, and nucleic acids by glucose. The formation and accumulation of AGEs are known to progress at an accelerated rate in diabetes. AGEs either act on the pro-inflammatory cell surface receptors called RAGE or bind to the circulating anti-inflammatory sRAGE that prevents activation of cell-surface RAGE by AGEs and other proinflammatory ligands. Pregnancy has been found to induce a significant increase in RAGE protein levels in both myometrium and omental vasculature. This review will focus on the role of AGEs and RAGE in pregnancy complicated by DM type 1 as well as ways to reduce the rate of congenital malformations in the offspring of diabetic type 1 women.

Background Gestational diabetes mellitus (GDM) is a form of diabetes that occurs in pregnancy. Although GDM usually resolves following birth, it is associated with significant morbidities for mother and baby both perinatally and in the long term. There is strong evidence to support treatment for GDM. However, there is little consensus on whether or not screening for GDM will improve maternal and infant health and if so, the most appropriate protocol to follow. Objectives To assess the effects of different methods of screening for gestational diabetes mellitus and maternal and infant outcomes. Search methods We searched the Cochrane Pregnancy and Childbirth Group’s Trials Register (April 2010). Selection criteria Randomised and quasi-randomised trials evaluating the effects of different methods of screening for gestational diabetes mellitus. Data collection and analysis Two review authors independently conducted data extraction and quality assessment. We resolved disagreements through discussion or through a third author. Main results We included four trials involving 3972 women were included in the review. One quasi-randomised trial compared risk factor screening with universal or routine screening by 50 g oral glucose challenge testing. Women in the universal screening group were more likely to be diagnosed with GDM (one trial, 3152 women, risk ratio (RR) 0.44 95% confidence interval (CI) 0.26 to 0.75). Infants of mothers in the risk factor screening group were born marginally earlier than infants of mothers in the routine screening group (one trial, 3152 women, mean difference −0.15 weeks, 95% CI −0.27 to −0.53). The remaining three trials evaluated different methods of administering a 50 g glucose load. Two small trials compared glucose monomer with glucose polymer testing, with one of these trials including a candy bar group. One trial compared a glucose solution with food. No differences in diagnosis of GDM were found between each comparison. Overall, women drinking the glucose monomer experienced fewer side effects from testing than women drinking the glucose polymer (two trials, 151 women, RR 2.80, 95% CI 1.10 to 7.13). However, we observed high heterogeneity between the trials for this result (I2 = 61%). Authors’ conclusions There was insufficient evidence to determine if screening for gestational diabetes, or what types of screening, can improve maternal and infant health outcomes. PMID:20614455

Childhood obesity is associated with abnormal glucose metabolism and type 2 diabetes mellitus (T2DM). This study evaluated the prevalence of abnormal glucose metabolism in asymptomatic obese children and adolescents, and determined the percentage of T2DM development after 3-6 years of follow-up. During 2007-2013, 177 obese children and adolescents who had normal fasting plasma glucose (FPG<100 mg/dL) were given an oral glucose tolerance test (OGTT). The participants were classified into four groups: normal glucose tolerance (NGT), NGT-hyperinsulinemia (NGT-HI), impaired glucose tolerance (IGT), and diabetes mellitus (DM). Blood chemistries, including FPG, glycated hemoglobin, and lipid profiles, and liver function test were performed every 6-12 months or when the patient developed any symptom or sign indicative of diabetes. Glucose metabolism alterations were detected in 81.4% of the participants: 63.8% with NGT-HI, 15.3% with IGT, and 2.3% with T2DM. The median levels of homeostasis model assessment-insulin resistance (HOMA-IR) in patients with IGT (8.63) were significantly greater than those in the patients with NGT (4.04) (p<0.01). During the follow-up, 22 patients (14.4%) developed T2DM significantly more from the IGT group (nine of 33 cases, 27.3%) than the NGT-HI group (12 of 108 cases, 11.1%) (p=0.022). The predicting parameters for T2DM conversion were weight status, body mass index (BMI), FBG, fasting insulin, alanine transaminase (ALT) levels, and HOMA-IR. Glucose metabolism alteration was commonly found among obese adolescents. Factors associated with T2DM development were greater weight status and the severity of insulin resistance as shown by higher HOMA-IR levels.

The renal sodium-glucose cotransporter 2 (SGLT2) plays an important role in the reuptake of filtered glucose in the proximal tubule and therefore may be an attractive target for the treatment of diabetes mellitus. This study characterizes the pharmacological profile of TS-071 ((1S)-1,5-anhydro-1-[5-(4-ethoxybenzyl)-2-methoxy-4-methylphenyl]-1-thio-D-glucitol hydrate), a novel SGLT2 inhibitor in vitro and in vivo. Inhibition of glucose uptake by TS-071 was studied in CHO-K1 cells stably expressing either human SGLT1 or SGLT2. Single oral dosing studies were performed in rats, mice and dogs to assess the abilities of TS-071 to increase urinary glucose excretion and to lower plasma glucose levels. TS-071 inhibited SGLT2 activity in a concentration-dependent manner and was a potent and highly selective inhibitor of SGLT2. Orally administered TS-071 increased urinary glucose excretion in Zucker fatty rats and beagle dogs at doses of 0.3 and 0.03 mg·kg(-1) respectively. TS-071 improved glucose tolerance in Zucker fatty rats without stimulating insulin secretion and reduced hyperglycaemia in streptozotocin (STZ)-induced diabetic rats and db/db mice at a dose of 0.3 mg·kg(-1). These data indicate that TS-071 is a potent and selective SGLT2 inhibitor that improves glucose levels in rodent models of type 1 and 2 diabetes and may be useful for the treatment for diabetes mellitus. © 2011 The Authors.

To compare the effects of three ready-to-eat mixed meals, with a high fiber content and low glycemic index, on postprandial glycemic and insulinemic response in patients with Type 2 diabetes mellitus (T2DM). The current study followed a prospective, three-way, cross-over design. Twenty-four patients with T2DM consumed three ready-to-eat mixed meals, i.e., "wild greens pie" (meal 1), "chicken burgers with boiled vegetables" (meal 2) and "vegetable moussaka" (meal 3) and an oral glucose load, all providing 50 g of carbohydrates. Venous blood was collected at 0, 30, 60, 90 and 120 min postprandial. Statistical analyses included repeated measures analysis of variance and calculations of the area under the glucose and insulin curves (AUC) for each one of the test meals and the oral glucose load. Patients consuming each one of the three mixed meals showed better postprandial glycemic responses compared to the oral glucose load (P < 0.001). Furthermore, patients consuming meal 3 showed a better insulinemic response compared to the oral glucose load and meal 1, after 60 and 120 min postprandial, respectively (P < 0.05). In addition, the increase observed in HOMA-IR values from T0 to T120 was significantly lower for meal 3, compared to the oral glucose load (P < 0.001). The three ready-to-eat mixed meals examined in the present study were found to elicit significantly lower glycemic responses compared to the oral glucose load in diabetic patients. The mixed meals examined in the present study could be proposed as effective, palatable and practical solutions for diabetics for glucose control.

Diabetes mellitus in newborns and infants.
Menon, P S; Khatwa, U A
2000-06-01
Diabetes mellitus is uncommon in infancy and newborn period. The two common forms seen are the transient and permanent forms of diabetes mellitus of the newborn. They have to be differentiated from the transient hyperglycemic states (Blood sugar > 125 mg/dl) seen in newborns who receive parenteral glucose infusions and in those with septicemia and CNS disorders. Transient diabetes mellitus of the newborn (TDNB) is defined as hyperglycemia occurring within the first month of life lasting at least 2 weeks and requiring insulin therapy. Most of these cases resolve spontaneously by 4 months. It has a reported incidence of 1 in 45,000 to 60,000 live births. The most likely etiology is a maturational delay of cAMP mediated insulin release. The clinical features include small for datedness, proneness for birth asphyxia, open-eye alert facies, dehydration, emaciation, polyuria and poydipsia. These children are prone to septicemia and urinary tract infections. They have hyperglycemia, glucosuria, absent or mild ketonuria, low basal insulin, C-peptide and IGF-1 levels. Treatment consists of hydration and judicious administration of insulin with close monitoring. Thirty percent of these children are likely to develop permanent neonatal diabetes. Compared to transient form, permanent diabetes mellitus is uncommon. It is usually due to pancreatic dysgenesis often associated with other malformations and rarely due to type 1 diabetes mellitus. The diagnosis is based on the demonstration of both exocrine and endocrine pancreatic dysfunction. These children are managed as type 1 diabetes mellitus. They are prone to develop the vascular complications of diabetes at an earlier date.

The awareness, treatment and control of diabetes mellitus (DM) can effectively reflect on the social status of diabetes conditions. Although several researchers have investigated the awareness, treatment and control rates of diabetes mellitus in China, little is known about their association with risk factors. This study aims to examine the relationship between risk factors and awareness, treatment and control of diabetes mellitus in northeast China. A cross-sectional survey was conducted in 2012. Multistage stratified random cluster sampling design was used to select participants aged 18 to 79 years old. The analysis was based on a representative sample of 1,854 adult subjects. Multivariable logistic regression analysis was used to examine socio-demographic factors associated with the levels of awareness, treatment and control of diabetes mellitus. The awareness, treatment, and control rates of diabetes mellitus were 64.1%, 52.9% and 44.2%, respectively. In the multivariable logistic regression analysis, family history of diabetes was significantly positively associated with awareness (OR, 2.145; 95% CI, 1.600-2.875) and treatment (OR, 2.021; 95% CI, 1.559-2.619) of diabetes mellitus, while negatively associated with control (OR, 0.671; 95% CI, 0.529-0.951). Cigarette smokers and alcohol drinkers were less likely than non-smokers and non-drinkers to be aware of their blood glucose levels (OR, 0.895, 0.614; 95% CI, 0.659-1.216, 0.446-0.844, respectively). Participants who frequently exercise were more likely to be aware of their diabetic conditions than people who never or rarely exercise (OR, 2.003; 95% CI, 1.513-2.651). We found that the awareness and treatment of diabetes mellitus were positively associated with age and were high in participants with a family history of diabetes and those who exercise frequently, but low for cigarette smokers and alcohol drinkers. Participants with a family history of diabetes had their diabetic condition poorly controlled.

Background— Maternal diabetes mellitus is associated with an increased risk of offspring congenital heart defects (CHD); however, the causal mechanism is poorly understood. We further investigated this association in a Danish nationwide cohort. Methods and Results— In a national cohort study, we identified 2 025 727 persons born from 1978 to 2011; among them were 7296 (0.36%) persons exposed to maternal pregestational diabetes mellitus. Pregestational diabetes mellitus was identified by using the National Patient Register and individual-level information on all prescriptions filled in Danish pharmacies. Persons with CHD (n=16 325) were assigned to embryologically related cardiac phenotypes. The CHD prevalence in the offspring of mothers with pregestational diabetes mellitus was 318 per 10 000 live births (n=232) in comparison with a baseline risk of 80 per 10 000; the adjusted relative risk for CHD was 4.00 (95% confidence interval, 3.51–4.53). The association was not modified by year of birth, maternal age at diabetes onset, or diabetes duration, and CHD risks associated with type 1 (insulin-dependent) and type 2 (insulin-independent) diabetes mellitus did not differ significantly. Persons born to women with previous acute diabetes complications had a higher CHD risk than those exposed to maternal diabetes mellitus without complications (relative risk, 7.62; 95% confidence interval, 5.23–10.6, and relative risk, 3.49; 95% confidence interval, 2.91–4.13, respectively; P=0.0004). All specific CHD phenotypes were associated with maternal pregestational diabetes mellitus (relative risk range, 2.74–13.8). Conclusions— The profoundly increased CHD risk conferred by maternal pregestational diabetes mellitus neither changed over time nor differed by diabetes subtype. The association with acute pregestational diabetes complications was particularly strong, suggesting a role for glucose in the causal pathway. PMID:27166384

Pituitary gigantism causing diabetic ketoacidosis.
Alvi, N S; Kirk, J M
1999-01-01
Although growth hormone excess (acromegaly) in association with glucose intolerance and diabetes mellitus is well documented in adult medicine, it is much less common in the paediatric age group. We report the case of a 13 year-old boy who presented with tall stature secondary to a large growth hormone secreting adenoma of the pituitary gland. Random growth hormone was 630 mIU/l and did not suppress during an oral glucose tolerance test. Following debulking of the tumour, he developed diabetic ketoacidosis requiring insulin treatment, but after further surgery glucose handling returned to normal. He has been started on testosterone to arrest further increase in height.

Acid-base and hormonal abnormalities in dogs with naturally occurring diabetes mellitus.
Durocher, Lawren L; Hinchcliff, Kenneth W; DiBartola, Stephen P; Johnson, Susan E

To examine acid-base and hormonal abnormalities in dogs with diabetes mellitus. Cross-sectional study. 48 dogs with diabetes mellitus and 17 healthy dogs. Blood was collected and serum ketone, glucose, lactate, electrolytes, insulin, glucagon, cortisol, epinephrine, norepinephrine, nonesterified fatty acid, and triglyceride concentrations were measured. Indicators of acid-base status were calculated and compared between groups. Serum ketone and glucose concentrations were significantly higher in diabetic than in healthy dogs, but there was no difference in venous blood pH or base excess between groups. Anion gap and strong ion difference were significantly higher and strong ion gap and serum bicarbonate concentration were significantly lower in the diabetic dogs. There were significant linear relationships between measures of acid-base status and serum ketone concentration, but not between measures of acid-base status and serum lactate concentration. Serum insulin concentration did not differ significantly between groups, but diabetic dogs had a wider range of values. All diabetic dogs with a serum ketone concentration > 1,000 micromol/L had a serum insulin concentration < 5 microU/mL. There were strong relationships between serum ketone concentration and serum glucagon-insulin ratio, serum cortisol concentration, and plasma norepinephrine concentration. Serum beta-hydroxybutyrate concentration, expressed as a percentage of serum ketone concentration, decreased as serum ketone concentration increased. Results suggested that ketosis in diabetic dogs was related to the glucagon-insulin ratio with only low concentrations of insulin required to prevent ketosis. Acidosis in ketotic dogs was attributable largely to high serum ketone concentrations.

Preventing progression from gestational diabetes mellitus to diabetes: A thought-filled review.
Kasher-Meron, Michal; Grajower, Martin M
2017-10-01
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.

2017-01-01
Diabetic retinopathy is one of most common diabetic microvascular complications. In recent years the incidence of the disease has increased, hence early diagnosis and treatment are of great importance. In order to find reliable biological indexes to diagnose and treat type-two diabetes mellitus promptly, this study focused on the correlation between Cystatin C (Cys C) and retinopathy of type-two diabetes mellitus patients. One hundred and eighty type-two diabetes mellitus patients and one hundred healthy controls (the control group) were chosen in this study. Of the patients ninety-eight patients had typetwo diabetes mellitus without retinopathy (non-diabetic retinopathy group) and eighty-two had typetwo diabetes mellitus with retinopathy (diabetic retinopathy group). Correlation of Cys C and typetwo diabetic retinopathy was analyzed by examining the waist-hip ratio, fasting blood glucose (FBG), total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), glycosylated hemoglobin (HbA1c), and Cys C of both groups. The results showed that FBG, TC, TG, LDL-C, HbA1c, Cys C in the type-two diabetes mellitus patients group were higher than those of the control group (P less than 0.05). Age, course of diabetes, FBG, HbA1c, and Cys C levels were statistically significant in both the DR group and NDR group (P less than 0.05). The result of logistic regression analysis indicates that there was a positive correlation between type-two diabetic retinopathy development and age, course of diabetes, and Cys C level (P less than 0.05). Thus, it can be seen that changes of Cys C levels can assist early diagnosis and treatment of diabetic retinopathy to some extent. The patients with high Cys C level, long course of diabetes, and old age are more likely to have diabetic retinopathy.

Platelets from patients with diabetes mellitus are hyperactive. Hyperactivated platelets may contribute to cardiovascular complications and inadequate responses to antiplatelet agents in the setting of diabetes mellitus. However, the underlying mechanism of hyperactivated platelets is not completely understood. We measured P2Y 12 expression on platelets from patients with type 2 diabetes mellitus and on platelets from rats with diabetes mellitus. We also assayed platelet P2Y 12 activation by measuring cAMP and VASP phosphorylation. The antiplatelet and antithrombotic effects of AR-C78511 and cangrelor were compared in rats. Finally, we explored the role of the nuclear factor-κB pathway in regulating P2Y 12 receptor expression in megakaryocytes. Platelet P2Y 12 levels are 4-fold higher in patients with type 2 diabetes mellitus compared with healthy subjects. P2Y 12 expression correlates with ADP-induced platelet aggregation (r=0.89, P <0.01). P2Y 12 in platelets from patients with diabetes mellitus is constitutively activated. Although both AR-C78511, a potent P2Y 12 inverse agonist, and cangrelor have similar antiplatelet efficacy on platelets from healthy subjects, AR-C78511 exhibits more powerful antiplatelet effects on diabetic platelets than cangrelor (aggregation ratio 36±3% versus 49±5%, respectively, P <0.05). Using a FeCl 3 -injury mesenteric arteriole thrombosis model in rats and an arteriovenous shunt thrombosis model in rats, we found that the inverse agonist AR-C78511 has greater antithrombotic effects on GK rats with diabetes mellitus than cangrelor (thrombus weight 4.9±0.3 mg versus 8.3±0.4 mg, respectively, P <0.01). We also found that a pathway involving high glucose-reactive oxygen species-nuclear factor-κB increases platelet P2Y 12 receptor expression in diabetes mellitus. Platelet P2Y 12 receptor expression is significantly increased and the receptor is constitutively activated in patients with type 2 diabetes mellitus, which contributes to platelet hyperactivity and limits antiplatelet drug efficacy in type 2 diabetes mellitus. © 2017 American Heart Association, Inc.

Objectives To study the role of nursing home (NH) admission and dementia status on the provision of five procedures related to diabetes mellitus. Design Retrospective cohort study using data from a large prospective study in which an expert panel determined the prevalence of dementia. Setting Fifty-nine Maryland NHs. Participants Three hundred ninety-nine new admission NH patients with diabetes mellitus. Measurements Medicare administrative claims records matched to the NH medical record data were used to measure procedures related to diabetes mellitus received in the year before NH admission and up to a year after admission (and before discharge). Procedures included glycosylated hemoglobin, fasting blood glucose, dilated eye examination, lipid profile, and serum creatinine. Results For all but dilated eye examinations, higher rates of procedures related to diabetes mellitus were seen in the year after NH admission than in the year before. Residents without dementia received more procedures than those with dementia, although this was somewhat attenuated after controlling for demographic, health, and healthcare utilization variables. Persons without dementia experience greater increases in procedure rates after admission than those with dementia. Conclusion The structured environment of care provided by the NH may positively affect monitoring procedures provided to elderly persons with diabetes mellitus, especially those without dementia. Medical decisions related to the risks and benefits of intensive treatment for diabetes mellitus to patients of varying frailty and expected longevity may lead to lower rates of procedures for residents with dementia.

Diabetes mellitus is a serious health problem in both dogs and humans. Certain dog breeds show high prevalence of the disease, whereas other breeds are at low risk. Fructosamine and glycated haemoglobin (HbA1c) are two major biomarkers of glycaemia, where serum concentrations reflect glucose turnover over the past few weeks to months. In this study, we searched for genetic factors influencing variation in serum fructosamine concentration in healthy dogs using data from nine dog breeds. Considering all breeds together, we did not find any genome-wide significant associations to fructosamine serum concentration. However, by performing breed-specific analyses we revealed an association on chromosome 3 (pcorrected ≈ 1:68 × 10-6) in Belgian shepherd dogs of the Malinois subtype. The associated region and its close neighbourhood harbours interesting candidate genes such as LETM1 and GAPDH that are important in glucose metabolism and have previously been implicated in the aetiology of diabetes mellitus. To further explore the genetics of this breed specificity, we screened the genome for reduced heterozygosity stretches private to the Belgian shepherd breed. This revealed a region with reduced heterozygosity that shows a statistically significant interaction (p = 0.025) with the association region on chromosome 3. This region also harbours some interesting candidate genes and regulatory regions but the exact mechanisms underlying the interaction are still unknown. Nevertheless, this finding provides a plausible explanation for breed-specific genetic effects for complex traits in dogs. Shepherd breeds are at low risk of developing diabetes mellitus. The findings in Belgian shepherds could be connected to a protective mechanism against the disease. Further insight into the regulation of glucose metabolism could improve diagnostic and therapeutic methods for diabetes mellitus.

Approximately 7% of pregnant women develop gestational diabetes mellitus (GDM), a usually transient form of diabetes mellitus, because of the production of some placental and maternal adipose tissue elaborated hormones that alter glucose metabolism. In most women the disorder resolves at delivery, but within 10 years 50% to 70% of these women go on to develop type 2 diabetes. The identification of women with past medical histories of GDM is a clinically useful marker for alerting the dentist to patients at heightened risk of occult type 2 diabetes, with a possible greater risk of developing periodontal disease and dental caries. Screening these patients for diabetes and establishing a preventative dental regimen may result in reducing the number of women with undiagnosed diabetes and diabetes-associated dental and cardiovascular diseases.

Diabetes mellitus is a dangerous disease worldwide. Indonesia has 10 million diabetic and 17.9 million prediabetic citizens. Unfortunately, less than half of these diabetic individuals are aware of their conditions and less than 1% of those receiving medical treatment achieve their healing targets. Because acupressure is believed to be an effective treatment without the use of drugs, in this study we investigated acupressure as a comfortable and effective way of treating patients with diabetes mellitus. This pilot study involved 30 participants who were split into two groups: 15 each in the experimental and the control groups. The experimental group underwent acupressure at the Zusanli (ST-36) acupoint for 30 minutes per visit for 11 weeks, whereas the control group continued their regular treatment; participants in both groups had their blood glucose randomly checked weekly. Data were analyzed using the Generalized Estimating Equation model; the result showed that the two groups were significantly different (p=0.331 > α=0.05; mean difference=99.14; Bonferroni sig. p=0.000 < α=0.05) and that acupressure at ST-36 was effective in reducing blood sugar. This research showed that acupressure was an effective method for reducing blood glucose and was helpful for reducing complications due to diabetes.

Treatment of Diabetes Mellitus Using iPS Cells and Spice Polyphenols
Chen, Liang
2017-01-01
Diabetes mellitus is a chronic disease that threatens human health. The disease is caused by a metabolic disorder of the endocrine system, and long-term illness can lead to tissue and organ damage to the cardiovascular, endocrine, nervous, and urinary systems. Currently, the disease prevalence is 11.4%, the treatment rate is 48.2%, and the mortality rate is 2.7% worldwide. Comprehensive and effective control of diabetes, as well as the use of insulin, requires further study to develop additional treatment options. Here, we reviewed the current reprogramming of somatic cells using specific factors to induced pluripotent stem (iPS) cells capable of repairing islet β cell damage in diabetes patients to treat patients with type 1 diabetes mellitus. We also discuss the shortcomings associated with clinical use of iPS cells. Additionally, certain polyphenols found in spices might improve glucose homeostasis and insulin resistance in diabetes patients, thereby constituting promising options for the treatment of type 2 diabetes.

Physical activity improves well-being and reduces the risk of heart disease, cancer and type 2 diabetes mellitus in the general population. In individuals with established type 2 diabetes, physical activity improves glucose and lipid levels, reduces weight and improves insulin resistance. In type 1 diabetes mellitus, however, the benefits of physical activity are less clear. There is poor evidence for a beneficial effect of physical activity on glycaemic control and microvascular complications, and significant risk of harm through hypoglycaemia. Here we review the literature relating to physical activity and health in type 1 diabetes. We examine its effect on a number of outcomes, including glycaemic control, lipids, blood pressure, diabetic complications, well-being and overall mortality. We conclude that whilst there is sufficient evidence to recommend physical activity in the management of type 1 diabetes, it is still unclear as to what form, duration and intensity should be recommended and whether there is benefit for many of the outcomes examined.

We studied 101 growth-retarded children from the population of Ancona (Italy). Plasma growth hormone (GH) levels at the end of insulin and clonidine tests were considered for classification of children into 3 categories according to severity of GH deficit: total deficit of GH (TD), partial deficit (PD, and familiar short stature (FSS; no deficit of GH). The BGLIIA*2/BGLIIB*1 haplotype of GH cluster that was previously found to be negatively associated with severe glucose intolerance in non-insulin-dependent diabetes mellitus (NIDDM) is negatively associated with GH deficit in growth-retarded children. The hypothesis that intrauterine growth retardation and glucose intolerance in adult life could be phenotypes of the same underlying genotype has been recently put forward. The present observation suggests that genes influencing both growth and glucose tolerance are encoded in the GH cluster. Copyright 2002 by W.B. Saunders Company

Dynamics of insulin and glucagon secretion were investigated by using a new model of spontaneous diabetes rats produced by the repetition of selective breeding in our laboratories. The perfusion experiments of the pancreas showed that the early phase of insulin secretion to continuous stimulation with glucose was specifically impaired, although the response of the early phase to arginine was preserved. The glucose-induced insulin secretion in the nineth generation (F8) which had a more remarkably impaired glucose tolerance was more reduced than in the sixth generation (F5). No significant difference of glucagon secretion in response to arginine or norepinephrine was noted between the diabetes rats and control ones. The present data indicate that the defective insulin secretion is a primary derangement in a diabetic state of the spontaneous diabetes rat. This defect in the early phase of glucose-induced insulin secretion suggests the specific impairment of the recognition of glucose by the pancreatic beta-cells. The spontaneous diabetes rats are very useful as a model of disease for investigating pathophysiology of non-insulin dependent diabetes mellitus.

We examined the association of serum ferritin levels with metabolic syndrome (MS) and diabetes mellitus in a representative sample of the adult South Korean population using data from the 2008 Korean National Health and Nutrition Examination Survey. We conducted a cross-sectional study of 6311 adults older than 20 years who participated in the 2008 Korean National Health and Nutrition Examination Survey. Metabolic syndrome was defined as the presence of at least 3 of the following: elevated blood pressure, low high-density lipoprotein cholesterol, elevated serum triglycerides, elevated plasma glucose, and abdominal obesity. Diabetes mellitus was defined as fasting glucose of at least 126 mg/dL. Insulin resistance was determined using the homeostasis model assessment estimate of insulin resistance. In a representative sample of the adult Korean population, MS was more prevalent in the highest quartile compared with the lowest quartile of serum ferritin concentrations in women following adjustments for age, education, smoking, alcohol intake, body mass index, aspartate aminotransferase, and alanine aminotransferase. Diabetes mellitus was more prevalent in the highest quartile compared with the lowest quartile of serum ferritin concentrations in premenopausal women and men. The geometric means of fasting insulin and insulin resistance determined using the homeostasis model assessment of insulin resistance in the fourth serum ferritin quartiles of postmenopausal women and men were significantly higher compared with those in the first quartile of the respective groups. The present study demonstrates that elevated serum ferritin concentrations are associated with an increased risk of MS and diabetes mellitus in a representative sample of the adult South Korean population.
