    Husen R, Pihie AH, Nallappan M
    J Ethnopharmacol, 2004 Dec;95(2-3):205-8.
    PMID: 15507337 DOI: 10.1016/j.jep.2004.07.004
    Screening of aqueous extract of Phyllantus niruri (PL), Zingiber zerumbet (ZG), Eurycoma longifolia (TA-a and TA-b) and Andrographis paniculata (AP) to determine their blood glucose lowering effect were conducted in normoglycaemic and Streptozotocin-induced hyperglycaemic rats. Significant reduction in blood glucose level at 52.90% was shown when hyperglycaemic rats were treated with 50 mg/kg body weight (BW) aqueous extract of AP. This effect is enhanced when freeze-dried material was used, where 6.25 mg/kg BW gave 61.81% reduction in blood glucose level. In the administration of TA-a and TA-b, positive results in hyperglyacaemic rats were only obtained when 150 mg/kg BW of the aqueous extract was used. No significant reduction in blood glucose level were shown in hyperglycaemic rats treated with PL and ZG at all concentrations used (50, 100 and 150 mg/kg BW). In normoglycaemic rats, no significant reduction was noted when all the same extracts were used.

    Prim Care Diabetes, 2015 Aug;9(4):275-82.
    PMID: 25457621 DOI: 10.1016/j.pcd.2014.10.002
    AIMS: The aim of this study was to evaluate attitude and treatment satisfaction of women suffering from GDM and their association with glycaemic level.
    METHODS: A cross sectional study was conducted in antenatal clinic of Hospital Pulau Pinang, Malaysia from June to December 2013 on the sample of 175 patients. Data was collected through modified version of Diabetes Integration Scale (ATT-19) and Diabetes Treatment Satisfaction Questionnaires (DSTQs). Glycaemic level was evaluated in terms of Fasting Plasma Glucose (FPG). Three most recent values of FPG (mmol/l) were taken from patients medical profiles and their mean was calculated. Descriptive and inferential statistics were used for data analysis.
    RESULTS: A total of 166 patients were included in final analysis. Only 35 (21.1%) patients had positive attitude and 122 (73.5%) of patients had adequate treatment satisfaction. There was no significant association of total mean ATT-19 score with age, ethnicity, educational level, occupational status, family history and type of therapy. For treatment satisfaction statistically significant association was present only between total mean treatment satisfaction score and educational level. Patients with negative attitude and inadequate treatment satisfaction had higher mean glycaemic level.
    CONCLUSIONS: It is concluded that more than two folds of patients were satisfied with their ongoing treatment but majority of the patients were feeling difficulty in active coping measures for the management of GDM.

    Hussein Z, Lim-Abrahan MA, Jain AB, Goh SY, Soewondo P
    Diabetes Res Clin Pract, 2013 Apr;100 Suppl 1:S24-9.
    PMID: 23647714 DOI: 10.1016/S0168-8227(13)70006-8
    Aim: To evaluate the safety and effectiveness of biphasic insulin aspart 30 (BIAsp 30) in ASEAN type 2 diabetes (T2D) patients switched from biphasic human insulin (BHI) in the non-interventional 24-week A₁chieve study.

    Methods: Indonesian, Malaysian, Filipino and Singaporean patients switched from BHI to BIAsp 30 at their physicians' discretion were included. The incidence of serious adverse drug reactions (SADRs), including major hypoglycaemia was the primary endpoint. Changes in hypoglycaemia, glycated haemoglobin A1c (HbA1c), fasting plasma glucose (FPG), postprandial plasma glucose (PPPG), lipids, body weight and systolic blood pressure were also evaluated. Quality of life (QoL) was measured using the EQ-5D questionnaire.

    Results: For the 465 patients included (mean ± SD age: 56 ± 10.3 years, diabetes duration: 9.7 ± 7.1 years, baseline HbA1c: 9.4 ± 1.8%), the mean pre-study BHI dose was 0.62 ± 0.28 IU/kg and 63.4% were dosing BHI twice daily (bid). The mean baseline BIAsp 30 dose was 0.65 ± 0.27 U/kg, titrated up to 0.71 ± 0.28 U/kg over 24 weeks, and most patients continued bid dosing. No SADRs or major hypoglycaemic episodes were reported. The proportion of patients reporting overall hypoglycaemia decreased significantly from 10.8% at baseline to 3.4% at Week 24 (p < 0.0001). Significant improvements in glycaemic control were noted (HbA1c: -1.4 ± 1.7%, FPG: -56.7 ± 72.5 mg/dL, post-breakfast PPPG: -84.8 ± 82.8 mg/dL, p < 0.001). Mean QoL improved by +6.6 ± 14.6 points (p < 0.001).

    Conclusion: BIAsp 30 was well-tolerated and significantly increased glycaemic control in this ASEAN subgroup poorly controlled on BHI.

    Ibrahim MF, Abd-Aziz S, Razak MN, Phang LY, Hassan MA
    Appl Biochem Biotechnol, 2012 Apr;166(7):1615-25.
    PMID: 22391689 DOI: 10.1007/s12010-012-9538-6
    Acetone-butanol-ethanol (ABE) production from renewable resources has been widely reported. In this study, Clostridium butyricum EB6 was employed for ABE fermentation using fermentable sugar derived from treated oil palm empty fruit bunch (OPEFB). A higher amount of ABE (2.61 g/l) was produced in a fermentation using treated OPEFB as the substrate when compared to a glucose based medium that produced 0.24 g/l at pH 5.5. ABE production was increased to 3.47 g/l with a yield of 0.24 g/g at pH 6.0. The fermentation using limited nitrogen concentration of 3 g/l improved the ABE yield by 64%. The study showed that OPEFB has the potential to be applied for renewable ABE production by C. butyricum EB6.

    White rice (WR) is a major staple food for people in developing countries and it may be responsible for the growing incidence of type 2 diabetes. Nonpregnant Female Sprague Dawley rats fed with WR or brown rice (BR) for 8 weeks were mated with age-matched male rats maintained on normal pellet over the same period. Offsprings were fed normal pellet after weaning until 8 weeks postdelivery. Rats fed with WR and their offsprings showed worsened oral glucose tolerance test, lower serum adiponectin levels, and higher weights, homeostatic model assessment of insulin resistance, serum retinol binding protein-4 levels, and leptin levels, compared with the normal and BR groups, suggesting an increased risk of insulin resistance. Furthermore, transcriptional levels of genes involved in insulin signaling showed different expression patterns in the liver, muscle, and adipose tissues of mothers and offsprings in both WR and BR groups. The results propose that the cycle of WR-induced insulin resistance in offsprings due to prenatal exposure, followed by their consumption of WR later in life may contribute to diabetes incidents. These findings are worth studying further.

  6. Molecular process of glucose uptake and glycogen storage due to hamamelitannin via insulin signalling cascade in glucose metabolism
    Issac PK, Guru A, Chandrakumar SS, Lite C, Saraswathi NT, Arasu MV, et al.
    Mol Biol Rep, 2020 Sep;47(9):6727-6740.

    Understanding the mechanism by which the exogenous biomolecule modulates the GLUT-4 signalling cascade along with the information on glucose metabolism is essential for finding solutions to increasing cases of diabetes and metabolic disease. This study aimed at investigating the effect of hamamelitannin on glycogen synthesis in an insulin resistance model using L6 myotubes. Glucose uptake was determined using 2-deoxy-D-[1-3H] glucose and glycogen synthesis were also estimated in L6 myotubes. The expression levels of key genes and proteins involved in the insulin-signaling pathway were determined using real-time PCR and western blot techniques. The cells treated with various concentrations of hamamelitannin (20 µM to 100 µM) for 24 h showed that, the exposure of hamamelitannin was not cytotoxic to L6 myotubes. Further the 2-deoxy-D-[1-3H] glucose uptake assay was carried out in the presence of wortmannin and Genistein inhibitor for studying the GLUT-4 dependent cell surface recruitment. Hamamelitannin exhibited anti-diabetic activity by displaying a significant increase in glucose uptake (125.1%) and glycogen storage (8.7 mM) in a dose-dependent manner. The optimum concentration evincing maximum activity was found to be 100 µm. In addition, the expression of key genes and proteins involved in the insulin signaling pathway was studied to be upregulated by hamamelitannin treatment. Western blot analysis confirmed the translocation of GLUT-4 protein from an intracellular pool to the plasma membrane. Therefore, it can be conceived that hamamelitannin exhibited an insulinomimetic effect by enhancing the glucose uptake and its further conversion into glycogen by regulating glucose metabolism.

  7. Functional characterisation and product specificity of Endo-β-1,3-glucanase from alkalophilic bacterium, Bacillus lehensis G1
    Jaafar NR, Khoiri NM, Ismail NF, Mahmood NAN, Abdul Murad AM, Abu Bakar FD, et al.
    Enzyme Microb Technol, 2020 Oct;140:109625.

    Endo-β-1,3-glucanase from alkalophilic bacterium, Bacillus lehensis G1 (Blg32) composed of 284 amino acids with a predicted molecular mass of 31.6 kDa is expressed in Escherichia coli and purified to homogeneity. Herein, Blg32 characteristics, substrates and product specificity as well as structural traits that might be involved in the production of sugar molecules are analysed. This enzyme functions optimally at the temperature of 70 °C, pH value of 8.0 with its catalytic activity strongly enhanced by Mn2+. Remarkably, the purified enzyme is highly stable in high temperature and alkaline conditions. It exhibits the highest activity on laminarin (376.73 U/mg) followed by curdlan and yeast β-glucan. Blg32 activity increased by 62% towards soluble substrate (laminarin) compared to insoluble substrate (curdlan). Hydrolytic products of laminarin were oligosaccharides with degree of polymerisation (DP) of 1 to 5 with the main product being laminaritriose (DP3). This suggests that the active site of Blg32 could recognise up to five glucose units. High concentration of Blg32 mainly produces glucose whilst low concentration of Blg32 yields oligosaccharides with different DP (predominantly DP3). A theoretical structural model of Blg32 was constructed and structural analysis revealed that Trp156 is involved in multiple hydrophobic stacking interactions. The amino acid was predicted to participate in substrate recognition and binding. It was also exhibited that catalytic groove of Blg32 has a narrow angle, thus limiting the substrate binding reaction. All these properties and knowledge of the subsites are suggested to be related to the possible mode of action of how Blg32 produces glucooligosaccharides.

    J Agric Food Chem, 2008 Sep 10;56(17):7877-84.
    PMID: 18702467 DOI: 10.1021/jf8015915
    In this present study, we investigated the effects of cocoa extract containing polyphenols and methylxanthines prepared from cocoa powder on the biochemical parameters of obese-diabetic (Ob-db) rats. Obese-diabetic (Ob-db) rats were developed using a high-fat diet (49% fat, 32% carbohydrate, and 19% protein from total energy, kcal) for 3 months, followed by a low dose (35 mg/kg body weight) streptozotocin (STZ) injection. Cocoa extract (600 mg/kg body weight/day) was given to the rats for 4 weeks. The results indicated that there were no significant differences in fasting plasma glucose and insulin level after 4 weeks of cocoa extract administration. Oral glucose tolerance test revealed that cocoa supplementation in Ob-db rats significantly (p < 0.05) reduced plasma glucose at 60 and 90 min compared to unsupplemented Ob-db rats. Plasma free fatty acid and oxidative stress biomarker (8-isoprostane) were significantly (p < 0.05) reduced after cocoa supplementation. Superoxide dismutase activity was enhanced in Ob-db compared to that in nonsupplemented rats. However, no change was observed in catalase activity. The results showed that cocoa supplementation had an effect on postprandial glucose control but not for long term (4 weeks). Moreover, cocoa supplementation could reduce circulating plasma free fatty acid and 8-isoprostane and may enhance the antioxidant defense system.

    Metabolic syndrome has been associated with an increased risk of cardiovascular disease and diabetes mellitus. The objective of this study was to determine gender differences in the prevalence and factors associated with metabolic syndrome in a rural Malay population. This cross-sectional study, conducted in Bachok, Kelantan, involved 306 respondents aged 18 to 70 years. The survey used a structured questionnaire to collect information on demographics, lifestyle, and medical history. Anthropometric measurements, such as weight, height, body mass index, waist and hip circumference, and blood pressure were measured. Venous blood samples were taken by a doctor or nurses and analyzed for lipid profile and fasting glucose. The overall prevalence of metabolic syndrome was 37.5% and was higher among females (42.9%). Being unemployed or a housewife and being of older age were independently associated with metabolic syndrome in a multivariate analysis. Weight management and preventive community-based programs involving housewives, the unemployed, and adults of poor education must be reinforced to prevent and manage metabolic syndrome effectively in adults.

    PMID: 749278
    One hundred and thirty-two newly diagnosed Asian diabetic patients (39 Malay, 30 Chinese and 63 Indians) have been studied in Kuala Lumpur. The highest proportion of diabetic patients were Indian and the lowest were Chinese. Vascular complications were equally common in Asian diabetic patients as in Europeans; coronary heart disease was relatively more common in Indians and cerebral vascular disease in Chinese. Twenty percent of all Asian diabetic patients requiring admission to hospital also had coronary heart disease, 9% had cerebral vascular disease and 8% had gangrene or ulceration of the feet. In Kuala Lumpur, diabetes is a very important risk factor for coronary heart disease: 17% of all patients admitted to the General Hospital with coronary heart disease were already diabetic.

  11. Fulltext Type 2 diabetes mellitus patients with poor glycaemic control have lower quality of life scores as measured by the Short Form-36
    Kamarul Imran M, Ismail AA, Naing L, Wan Mohamad WB
    Singapore Med J, 2010 Feb;51(2):157-62.
    PMID: 20358156
    INTRODUCTION: This study aimed to compare the quality of life based on the Short Form-36 (SF-36) between two different groups of type 2 diabetes mellitus patients with glycaemic control: those with a glycosylated haemoglobin (HbA1c) level at or below 7.5 percent and those above 7.5 percent.
    METHODS: In this cross-sectional study, a generic SF-36 questionnaire was self-administered to patients with type 2 diabetes mellitus. Based on the HbA1c level, the mean SF-36 scale scores were compared. The analysis of covariance was used to obtain the adjusted mean scores of the SF-36 scales while controlling for age and duration of type 2 diabetes mellitus.
    RESULTS: 150 patients with type 2 diabetes mellitus were analysed. There were 63 (42 percent) women and 87 (58 percent) men, and their mean HbA1c level was 8.9 percent (SD 2.4 percent). When comparing the two groups of patients with different HbA1c levels, the adjusted means of four scales: physical health functioning, general health, social functioning and mental health, differed significantly between the two. The SF-36 scale scores in type 2 diabetes mellitus patients were also lower than those of the SF-36 norms for the Malaysian population.
    CONCLUSION: Type 2 diabetes mellitus patients with poor glycaemic control had lower mean SF-36 scores in physical functioning, general health, social functioning and mental health, and the SF-36 scores in these patients were also lower than the SF-36 norms of the Malaysian population.

  12. Fulltext Glucan-rich polysaccharides from Pleurotus sajor-caju (Fr.) Singer prevents glucose intolerance, insulin resistance and inflammation in C57BL/6J mice fed a high-fat diet
    Kanagasabapathy G, Kuppusamy UR, Abd Malek SN, Abdulla MA, Chua KH, Sabaratnam V
    BMC Complement Altern Med, 2012;12:261.
    PMID: 23259700 DOI: 10.1186/1472-6882-12-261
    BACKGROUND: Pleurotus sajor-caju (P. sajor-caju) has been extremely useful in the prevention of diabetes mellitus due to its low fat and high soluble fiber content for thousands of years. Insulin resistance is a key component in the development of diabetes mellitus which is caused by inflammation. In this study, we aimed to investigate the in vivo efficacy of glucan-rich polysaccharide of P. sajor-caju (GE) against diabetes mellitus and inflammation in C57BL/6J mice fed a high-fat diet.
    METHODS: Diabetes was induced in C57BL/6J mice by feeding a high-fat diet. The mice were randomly assigned to 7 groups (n=6 per group). The control groups in this study were ND (for normal diet) and HFD (for high-fat diet). The treated groups were ND240 (for normal diet) (240 mg/kg b.w) and HFD60, HFD120 and HFD240 (for high-fat), where the mice were administrated with three dosages of GE (60, 120, 240 mg GE/kg b.w respectively). Metformin (2 mg/kg b.w) served as positive control. The glucose tolerance test, glucose and insulin levels were measured at the end of 16 weeks. Expressions of genes for inflammatory markers, GLUT-4 and adiponectin in the adipose tissue of the mice were assessed. One-way ANOVA and Duncan's multiple range tests (DMRT) were used to determine the significant differences between groups.
    RESULTS: GE treated groups improved the glucose tolerance, attenuated hyperglycemia and hyperinsulinemia in the mice by up-regulating the adiponectin and GLUT-4 gene expressions. The mice in GE treated groups did not develop insulin resistance. GE also down-regulated the expression of inflammatory markers (IL-6, TNF-α, SAA2, CRP and MCP-1) via attenuation of nuclear transcription factors (NF-κB).
    CONCLUSION: Glucan-rich polysaccharide of P. sajor-caju can serve as a potential agent for prevention of glucose intolerance, insulin resistance and inflammation.

    PMID: 28077198 DOI: 10.1017/S136898001600344X
    OBJECTIVE: To determine the relationship between BMI and risk of CVD mortality and all-cause mortality among Malaysian adults.

    DESIGN: Population-based, retrospective cohort study. Participants were followed up for 5 years from 2006 to 2010. Mortality data were obtained via record linkages with the Malaysian National Registration Department. Multiple Cox regression was applied to compare risk of CVD and all-cause mortality between BMI categories adjusting for age, gender and ethnicity. Models were generated for all participants, all participants the first 2 years of follow-up, healthy participants, healthy never smokers, never smokers, current smokers and former smokers.

    SETTING: All fourteen states in Malaysia.

    SUBJECTS: Malaysian adults (n 32 839) aged 18 years or above from the third National Health and Morbidity Survey.

    RESULTS: Total follow-up time was 153 814 person-years with 1035 deaths from all causes and 225 deaths from CVD. Underweight (BMI<18·5 kg/m2) was associated with a significantly increased risk of all-cause mortality, while obesity (BMI ≥30·0 kg/m2) was associated with a heightened risk of CVD mortality. Overweight (BMI=25·0-29·9 kg/m2) was inversely associated with risk of all-cause mortality. Underweight was significantly associated with all-cause mortality in all models except for current smokers. Overweight was inversely associated with all-cause mortality in all participants. Although a positive trend was observed between BMI and CVD mortality in all participants, a significant association was observed only for severe obesity (BMI≥35·0 kg/m2).

    CONCLUSIONS: Underweight was associated with increased risk of all-cause mortality and obesity with increased risk of CVD mortality. Therefore, maintaining a normal BMI through leading an active lifestyle and healthy dietary habits should continue to be promoted.

  14. Fulltext Prevention and management of new-onset diabetes mellitus in kidney transplantation
    Khong MJ, Chong CP
    Neth J Med, 2014 Apr;72(3):127-34.
    PMID: 24846925
    New-onset diabetes mellitus after transplantation (NODAT) is one of the complications that is increasingly occurring among kidney transplanted patients. It is associated with the risk of cardiovascular disease, graft failure and mortality. The risk of NODAT development increases with time from transplantation. Therefore, early detection and prompt action are essential in reducing the risk of NODAT and its complications. This paper aims to review the screening parameters, prevention and management strategies for NODAT in both pre- and post-transplantation conditions. The pre-transplant patient should be screened for diabetes and cardiometabolic risk factors. Blood glucose evaluation for the pre-transplantation period is important for early detection of impaired glucose tolerance (IGT) and impaired fasting glucose (IFG), which are highly associated with the incidence of NODAT. Post-kidney transplant patients should have periodical blood glucose monitoring with more frequent assessment in the initial phase. As early hyperglycaemia development is a strong predictor for NODAT, prompt intervention is needed. When NODAT develops, monitoring and control of blood glucose profile, lipid profile, microalbuminuria, diabetic complications and comorbid conditions is recommended. Immunosuppressive regimen modification may be considered as suggested by the Kidney Disease: Improving Global Outcomes (KDIGO) guideline to reverse or to improve the diabetes after weighing the risk of rejection and other potential adverse effects. Strategies for modifying immunosuppressive agents include dose reduction, discontinuation, and selection of calcineurin inhibitor (CNI), anti-metabolite agents, mammalian target of rapamycin inhibitors (mTORi), belatacept and corticosteroids. Lifestyle modification and a conventional anti-diabetic approach, as in the type 2 diabetes mellitus guidelines, are also recommended in NODAT management.

    PMID: 26264387 DOI: 10.1007/s00394-015-1007-x
    PURPOSE: To compare the effects of a high-calcium vitamin D-fortified milk with added FOS-inulin versus regular milk on serum parathyroid hormone, and bone turnover markers in premenopausal (Pre-M) and postmenopausal (PM) women over 12 weeks.

    METHODS: Premenopausal women (n = 136, mean age 41 (±5) years) and postmenopausal women [n = 121, mean age 59 (±4) years] were recruited, and each age group randomised into two groups to take two glasses per day of control = regular milk (500 mg calcium per day) or intervention (Int) = fortified milk (1000 mg calcium for pre-M women and 1200 mg calcium for PM women, 96 mg magnesium, 2.4 mg zinc, 15 µg vitamin D, 4 g FOS-inulin per day). At baseline, week 4 and week 12 serum minerals and bone biochemical markers were measured and bone density was measured at baseline.

    RESULTS: Mean 25-hydroxyvitamin D [25(OH) vitamin D3] levels among groups were between 49 and 65 nmol/L at baseline, and over the 12 weeks of supplementation, the fortified milk improved vitamin D status in both Int groups. CTx-1 and PINP reduced significantly in both Pre-M and PM groups over the 12 weeks, with the changes in CTx-1 being significantly different (P

    ScientificWorldJournal, 2014;2014:737263.
    PMID: 25180205 DOI: 10.1155/2014/737263
    Leucaena leucocephala had been traditionally used to treat diabetes. The present study was designed to evaluate in vitro "insulin-like" activities of Leucaena leucocephala (Lam.) deWit. aqueous fruit extract on lipid and glucose metabolisms. The ability of the extract to stimulate adipogenesis, inhibit lipolysis, and activate radio-labeled glucose uptake was assessed using primary rat adipocytes. Quantitative Real-Time RT-PCR was performed to investigate effects of the extract on expression levels of genes (protein kinases B, AKT; glucose transporter 4, GLUT4; hormone sensitive lipase, HSL; phosphatidylinositol-3-kinases, PI3KA; sterol regulatory element binding factor 1, Srebp1) involved in insulin-induced signaling pathways. L. leucocephala aqueous fruit extract stimulated moderate adipogenesis and glucose uptake into adipocytes when compared to insulin. Generally, the extract exerted a considerable level of lipolytic effect at lower concentration but decreased gradually at higher concentration. The findings concurred with RT-PCR analysis. The expressions of GLUT4 and HSL genes were upregulated by twofold and onefold, respectively, whereas AKT, PI3KA, and Srebp1 genes were downregulated. The L. leucocephala aqueous fruit extract may be potentially used as an adjuvant in the treatment of Type 2 diabetes mellitus and weight management due to its enhanced glucose uptake and balanced adipogenesis and lipolysis properties.

    PMID: 30684076 DOI: 10.1007/s10620-019-5477-1
    BACKGROUND AND AIMS: Sodium-glucose cotransporter-2 (SGLT2) inhibitors are a novel class of drugs that lower glucose by inducing renal glycosuria. We aimed to explore whether SGLT2 inhibitor added to the usual care for patients with type 2 diabetes mellitus (T2DM) and biopsy-proven nonalcoholic steatohepatitis (NASH) will benefit NASH histology.

    METHODS: In this investigator-initiated, single-arm, open-label, pilot study, nine biopsy-proven NASH patients with T2DM were given empagliflozin 25 mg daily for 24 weeks. Liver biopsy was repeated at the end of treatment. The histological outcomes were compared with the placebo group of a previous 48-week clinical trial.

    RESULTS: There was a significant reduction in body mass index (median change, Δ = -0.7 kg per m2, p = 0.011), waist circumference (Δ = -3 cm, p = 0.033), systolic blood pressure (Δ = -9 mmHg, p = 0.024), diastolic blood pressure (Δ = -6 mmHg, p = 0.033), fasting blood glucose (Δ = -1.7 mmol/L, p = 0.008), total cholesterol (Δ = -0.5 mmol/L, p = 0.011), gamma glutamyl transpeptidase (Δ = -19 U/L, p = 0.013), volumetric liver fat fraction (Δ = -7.8%, p = 0.017), steatosis (Δ = -1, p = 0.014), ballooning (Δ = -1, p = 0.034), and fibrosis (Δ = 0, p = 0.046). All histological components either remained unchanged or improved, except in one patient who had worsening ballooning. Empagliflozin resulted in significantly greater improvements in steatosis (67% vs. 26%, p = 0.025), ballooning (78% vs. 34%, p = 0.024), and fibrosis (44% vs. 6%, p = 0.008) compared with historical placebo.

    CONCLUSION: This pilot study provides primary histological evidence that empagliflozin may be useful for the treatment of NASH. This preliminary finding should prompt larger clinical trials to assess the effectiveness of empagliflozin and other SGLT2 inhibitors for the treatment of NASH in T2DM patients.

    Epidemiological evidence shows that diabetic patients are susceptible to high temperature weather, and brown adipose tissue (BAT) activity is closely related to type 2 diabetes (T2DM). Activation of BAT under cold stress helps improve T2DM. However, the impact of high temperature on the activity of BAT is still unclear. The study aimed to investigate the impact of heat stress on glucose and lipid metabolism in T2DM mice by influencing BAT activity. High-fat feeding and injecting streptozotocin (STZ) induced model of T2DM mice. All mice were randomly divided into three groups: a normal(N) group, a diabetes (DM) group and a heat stress diabetes (DMHS) group. The DMHS group received heat stress intervention for 3 days. Fasting blood glucose, fasting serum insulin and blood lipids were measured in all three groups. The activity of BAT was assessed by using quantitative real-time PCR (qRT-PCR), electron microscopy, and PET CT. Furthermore, the UHPLC-Q-TOF MS technique was employed to perform metabolomics analysis of BAT on both DM group and DMHS group. The results of this study indicated that heat stress aggravated the dysregulation of glucose and lipid metabolism, exacerbated mitochondrial dysfunction in BAT and reduced the activity of BAT in T2DM mice. This may be related to the abnormal accumulation of branched-chain amino acids (BCAAs) in the mitochondria of BAT.

  19. Fulltext Novel adiponectin-resistin (AR) and insulin resistance (IRAR) indexes are useful integrated diagnostic biomarkers for insulin resistance, type 2 diabetes and metabolic syndrome: a case control study

    Adiponectin and resistin are adipokines which modulate insulin action, energy, glucose and lipid homeostasis. Meta-analyses showed that hypoadiponectinemia and hyperresistinemia are strongly associated with increased risk of insulin resistance, type 2 diabetes (T2DM), metabolic syndrome (MS) and cardiovascular disease. The aim of this study was to propose a novel adiponectin-resistin (AR) index by taking into account both adiponectin and resistin levels to provide a better indicator of the metabolic homeostasis and metabolic disorders. In addition, a novel insulin resistance (IRAR) index was proposed by integration of the AR index into an existing insulin resistance index to provide an improved diagnostic biomarker of insulin sensitivity.

  20. Translating HbA1c measurements into estimated average glucose values in pregnant women with diabetes
    Law GR, Gilthorpe MS, Secher AL, Temple R, Bilous R, Mathiesen ER, et al.
    Diabetologia, 2017 04;60(4):618-624.
    PMID: 28105519 DOI: 10.1007/s00125-017-4205-7
    AIMS/HYPOTHESIS: This study aimed to examine the relationship between average glucose levels, assessed by continuous glucose monitoring (CGM), and HbA1clevels in pregnant women with diabetes to determine whether calculations of standard estimated average glucose (eAG) levels from HbA1c measurements are applicable to pregnant women with diabetes.
    METHODS: CGM data from 117 pregnant women (89 women with type 1 diabetes; 28 women with type 2 diabetes) were analysed. Average glucose levels were calculated from 5-7 day CGM profiles (mean 1275 glucose values per profile) and paired with a corresponding (±1 week) HbA1c measure. In total, 688 average glucose-HbA1c pairs were obtained across pregnancy (mean six pairs per participant). Average glucose level was used as the dependent variable in a regression model. Covariates were gestational week, study centre and HbA1c.
    RESULTS: There was a strong association between HbA1c and average glucose values in pregnancy (coefficient 0.67 [95% CI 0.57, 0.78]), i.e. a 1% (11 mmol/mol) difference in HbA1c corresponded to a 0.67 mmol/l difference in average glucose. The random effects model that included gestational week as a curvilinear (quadratic) covariate fitted best, allowing calculation of a pregnancy-specific eAG (PeAG). This showed that an HbA1c of 8.0% (64 mmol/mol) gave a PeAG of 7.4-7.7 mmol/l (depending on gestational week), compared with a standard eAG of 10.2 mmol/l. The PeAG associated with maintaining an HbA1c level of 6.0% (42 mmol/mol) during pregnancy was between 6.4 and 6.7 mmol/l, depending on gestational week.
    CONCLUSIONS/INTERPRETATION: The HbA1c-average glucose relationship is altered by pregnancy. Routinely generated standard eAG values do not account for this difference between pregnant and non-pregnant individuals and, thus, should not be used during pregnancy. Instead, the PeAG values deduced in the current study are recommended for antenatal clinical care.
