Vascular endothelial growth factor B improves impaired glucose tolerance through insulin-mediated inhibition of glucagon secretion

BACKGROUND Impaired glucose tolerance(IGT)is a homeostatic state between euglycemia and hyperglycemia and is considered an early high-risk state of diabetes.When IGT occurs,insulin sensitivity decreases,causing a reduction in insulin secretion and an increase in glucagon secretion.Recently,vascular endothelial growth factor B(VEGFB)has been demonstrated to play a positive role in improving glucose metabolism and insulin sensitivity.Therefore,we constructed a mouse model of IGT through high-fat diet feeding and speculated that VEGFB can regulate hyperglycemia in IGT by influencing insulin-mediated glucagon secretion,thus contributing to the prevention and cure of prediabetes.AIM To explore the potential molecular mechanism and regulatory effects of VEGFB on insulin-mediated glucagon in mice with IGT.METHODS We conducted in vivo experiments through systematic VEGFB knockout and pancreatic-specific VEGFB overexpression.Insulin and glucagon secretions were detected via enzyme-linked immunosorbent assay,and the protein expression of phosphoinositide 3-kinase(PI3K)/protein kinase B(AKT)was determined using western blot.Further,mRNA expression of forkhead box protein O1,phosphoenolpyruvate carboxykinase,and glucose-6 phosphatase was detected via quantitative polymerase chain reaction,and the correlation between the expression of proteins was analyzed via bioinformatics.RESULTS In mice with IGT and VEGFB knockout,glucagon secretion increased,and the protein expression of PI3K/AKT decreased dramatically.Further,in mice with VEGFB overexpression,glucagon levels declined,with the activation of the PI3K/AKT signaling pathway.CONCLUSION VEGFB/vascular endothelial growth factor receptor 1 can promote insulin-mediated glucagon secretion by activating the PI3K/AKT signaling pathway to regulate glucose metabolism disorders in mice with IGT.

Effects of Chinese Patent Drug Zishen Pills in Treatment of Elderly Patients with Impaired Glucose Tolerance(IGT)

[Objectives]To evaluate the efficacy of Zishen Pills(ZSP),a Chinese patent drug,in the treatment of elderly patients with impaired glucose tolerance(IGT)and its effects on the prevention of diabetes mellitus(DM).[Methods]Thirty-five IGT patients were randomized to receive 10 g of ZSP three times daily(ZSP group,n=24)or no drug intervention(control group,n=11)for 12 weeks.Oral glucose tolerance test,glycated hemoglobin A1c(HbA1c),body mass index,blood lipids levels,fasting insulin,and insulin resistance calculated using homeostatic model assessment(HOMA-IR)of all the patients were observed and compared before and after the treatment.[Results]Thirty participants completed the trial(20 in ZSP group and 10 in the control group).There were statistically significant decreases in plasma triglycerides(TG),fasting blood-glucose(FBG),2-h plasma glucose(2-h PG),HbA1c,and HOMA-IR in ZSP group compared with the control group after 12 weeks of treatment(P<0.05 or P<0.01).After 12 weeks of treatment,2(20.0%)patients returned to normal blood glucose,and 2(20.0%)patients turned into DM in control group,while in the ZSP group,9(45.0%)patients returned to normal blood glucose and 1(5.0%)patient turned into DM.[Conclusions]ZSP effectively improved glucose control,increased the conversion of IGT to normal glucose,and improved the insulin resistance in elderly patients with IGT.This Chinese patent drug may have a clinical value for IGT.

Risk factors for impaired glucose tolerance in obese children and adolescents

AIM:To investigate which obese children have an increased risk for impaired glucose tolerance(IGT),a risk factor for later diabetes.METHODS:We studied 169 European untreated obese children and adolescents with normal glucose tolerance at baseline.Waist circumference,fasting glucose,lipids,blood pressure,pubertal stage,2 h glucose in oral glucose tolerance test(oGTT),and HbA1c were deter mined at baseline and 1 year later.RESULTS:One year after baseline,19(11.2) children demonstrated IGT,4(2.4) children had impaired fas ting glucose,no(0) child suffered from diabetes,and 146(86) children still showed normal glucose tolerance.At baseline,the children with IGT and with normal glucose tolerance in a one-year follow-up did not differ significantly in respect of any analyzed parameter,apart from pubertal stage.The children developing IGT entered puberty significantly more frequently(37 vs 3,P < 0.001).One year after baseline,the childr en with IGT demonstrated significantly increased waist circumference,blood pressure values,insulin and triglyceride concentrations,and insulin resistance index HOMA.The children remaining in the normal glucose tolerance status 1 year after baseline did not demonstrate any significant changes.CONCLUSION:During the study period of 1 year,more than 10 of the obese children with normal glucose tolerance converted to IGT.Repeated screening with oGTT seems meaningful in obese children entering puberty or demonstrating increased insulin resistance,waist circumference,blood pressure,or triglyceride concen trations.

Effects of Metformin and Pioglitazone on impaired glucose tolerance patients—An open level prospective study

Introduction: impaired glucose tolerance (IGT) often leads to type 2 diabetes (T2DM) and macro vascular disease;and usually associated with insulin resistance. Pioglitazone and metformin are commonly used insulin sensitizers (IS);and can prevent or delay the development T2DM and macro vascular disease. This study was deployed to search the better IS between these two in relation to plasma glucose and lipid control;and physical parameter altering effect. Materials and methods: 100 IGT patients selected randomly from outpatients department following prefixed inclusion and exclusion criteria. Pioglitazone and metformin were administered sequentially. Washout period was 2 weeks. Total follow up period was 24 weeks. Results: 70 IGT patients had completed the study. Metformin had reduced plasma glucose (fasting & postprandial), lipids and physical parameters significantly (p < 0.05) more than Pioglitazone. Discussion: Metformin, a hepatic insulin sensitizer, is more effective than PPAR-□ agonist Pioglitazone in the treatment of IGT;and this is due to the expression of PPAR-□ is more in adipose tissue but postprandial utilization of plasma glucose is more in muscle tissue.

Scleredema Diabeticorum in a Patient with the Normal Range of the Hemoglobin A1c Level and Impaired Glucose Tolerance

Scleredema diabeticorum is an uncommon skin disorder showing a diffuse, symmetrical, and non-pitting persistent in-duration developing initially on the nape. It usually occurs in patients with poorly controlled or insulin-resistant diabetes mellitus. We present a 57-year-old woman with scleredema diabeticorum with hemoglobin A1c 6.1% (normal, 4.7% - 6.2%) and impaired glucose tolerance. Alcian blue staining at pH 7.0 illustrated deposits of acid mucopolysaccharides between the collagen bundles in the reticular dermis, but the staining at pH 1.5 did not show the deposits. This case indicates that scleredema diabeticorum may be an early indicator of undiagnosed diabetes mellitus in some cases, and that impaired glucose tolerance test should be performed for individuals with scleredema even though the hemoglobin A1c level is within the normal range.

Effect of Jiangtang Bushen Recipe (降糖补肾方) in Intervention Treatment of Patients with Impaired Glucose Tolerance

Objective:To evaluate the intervention effect of diet, exercise and Jiangtang Bushen Recipe (JBR, 降糖补肾方), a Chinese herbal recipe, in preventing the progress of patients with impaired glucose tolerance ( IGT ) to diabetes mellitus (DM) type 2. Methods: Fifty-one IGT patients with their diagnosis conformed to the diagnosis standard of WHO, 1999, were randomly divided into the control group (n = 26) and the TCM group (n=25). Patients in the control group attended to the educational course for DM and received dietotherapy and kinetotherapy, and to those in the TCM group, under these treatments, JBR was given additionally. Oral glucose tolerance test (OGTT), body weight index (BWI), levels of blood lipids and fasting insulin of all the patients were examined after 3 months, 6 months and 12 months of treatment. The total observation time was 1 year. Results:Except the 6 cases out of the 51 patients (11.7%), on whom the observa-tion discontinued, in the control group, as compared with before treatment, levels of fasting insulin and fasting blood glucose after treatment were not changed significantly ( P > 0. 05 ) , also insignificant difference was shown in levels of total cholesterol (TC) and triglyceride (TG), thoughthe two indexes lowered slightly after treatment (P>0. 05), but significant difference was shown in comparison of OGTT/2h, blood glucose and BWI (P<0. 05). While in the TCM group, fasting blood glucose was changed insignificantly (P> 0. 05) , but there was significant difference in comparison of fasting insulin, TC, BWI, OGTT/2h and plasma glucose levels (P<0. 01) respectively before and after treatment. At the end of the stud-y, the cumulative cases with conversion to diabetes were 3 (13. 6%) in the control group, and 1 (4. 3%) in the TCM group, x2 test showed insignificant difference in comparison of diabetes conversion rate between the two groups (P>0. 05), however, the TCM group showed a better year conversion rate of normal glucose tolerance than that in the control group (x2 = 8. 31, P<0. 01). Conclusion: TCM intervention is possibly effective in delaying the conversion of IGT to DM type 2, and plays integrative effeciency in impelling IGT patients to health. The favorable education and treatment of DM controlling, including dieto- and kineto-therapy may also be advantageous in IGT intervention, but could not be effective in blocking the advance of IGT.Original article on CJITWM (Chin) 2004 ;24 (4): 317

Microbiome and metabolome dysbiosis analysis in impaired glucose tolerance for the prediction of progression to diabetes mellitus

Gut microbiota and circulating metabolite dysbiosis predate important pathological changes in glucose metabolic disorders;however,comprehensive studies on impaired glucose tolerance(IGT),a diabetes mellitus(DM)precursor,are lacking.Here,we perform metagenomic sequencing and metabolomics on 47 pairs of individuals with IGT and newly diagnosed DM and 46 controls with normal glucose tolerance(NGT);patients with IGT are followed up after 4 years for progression to DM.Analysis of baseline data reveals significant differences in gut microbiota and serum metabolites among the IGT,DM,and NGT groups.In addition,13 types of gut microbiota and 17 types of circulating metabolites showed significant differences at baseline before IGT progressed to DM,including higher levels of Eggerthella unclassified,Coprobacillus unclassified,Clostridium ramosum,L-valine,L-norleucine,and L-isoleucine,and lower levels of Eubacterium eligens,Bacteroides faecis,Lachnospiraceae bacterium 3_1_46FAA,Alistipes senegalensis,Megaspaera elsdenii,Clostridium perfringens,α-linolenic acid,10E,12Z-octadecadienoic acid,and dodecanoic acid.A random forest model based on differential intestinal microbiota and circulating metabolites can predict the progression from IGT to DM(AUC=0.87).These results suggest that microbiome and metabolome dysbiosis occur in individuals with IGT and have important predictive values and potential for intervention in preventing IGT from progressing to DM.

Oral glucose tolerance test in diabetes,the old method revisited

The oral glucose tolerance test(OGTT)has been widely used both in clinics and in basic research for a long time.It is applied to diagnose impaired glucose tolerance and/or type 2 diabetes mellitus in individuals.Additionally,it has been employed in research to investigate glucose utilization and insulin sensitivity in animals.The main aim of each was quite different,and the details are also somewhat varied.However,the time or duration of the OGTT was the same,using the 2-h post-glucose load glycemia in both,following the suggestions of the American Diabetes Association.Recently,the use of 30-min or 1-h post-glucose load glycemia in clinical practice has been recommended by several studies.In this review article,we describe this new view and suggest perspectives for the OGTT.Additionally,quantification of the glucose curve in basic research is also discussed.Unlike in clinical practice,the incremental area under the curve is not suitable for use in the studies involving animals receiving repeated treatments or chronic treatment.We discuss the potential mechanisms in detail.Moreover,variations between bench and bedside in the application of the OGTT are introduced.Finally,the newly identified method for the OGTT must achieve a recommendation from the American Diabetes Association or another official unit soon.In conclusion,we summarize the recent reports regarding the OGTT and add some of our own perspectives,including machine learning and others.

Repetitiveness of the oral glucose tolerance test in children and adolescents

BACKGROUND Data regarding the most suitable diagnostic method for the diagnosis of glucose impairment in asymptomatic children and adolescents are inconclusive.Furthermore,limited data are available on the reproducibility of the oral glucose tolerance test(OGTT)in children and adolescents who are obese(OB).AIM To investigate the usefulness of the OGTT as a screening method for glucose dysregulation in children and adolescents.METHODS Eighty-one children and adolescents,41 females,either overweight(OW),OB or normal weight(NW)but with a strong positive family history of type 2 diabetes mellitus(T2DM),were enrolled in the present observational study from the Outpatient Clinic of Paediatric Endocrinology of the University Hospital of Patras in Greece.One or two 3-h OGTTs were performed and glucose,insulin and Cpeptide concentrations were measured at several time points(t=0 min,t=15 min,t=30 min,t=60 min,t=90 min,t=120 min,t=180 min).RESULTS Good repetitiveness was observed in the OGTT response with regard to T2DM,while low repetitiveness was noted in the OGTT response with regard to impaired glucose tolerance(IGT)and no repetitiveness with regard to impaired fasting glucose(IFG).In addition,no concordance was observed between IFG and IGT.During the 1st and 2nd OGTTs,no significant difference was found in the glucose concentrations between NW,OW and OB patients,whereas insulin and C-peptide concentrations were higher in OW and OB compared to NW patients at several time points during the OGTTs.Also,OW and OB patients showed a worsening insulin and C-peptide response during the 2nd OGTT as compared to the 1st OGTT.CONCLUSION In mild or moderate disorders of glucose metabolism,such as IFG and IGT,a diagnosis may not be reached using only one OGTT,and a second test or additional investigations may be needed.When glucose metabolism is profoundly impaired,as in T2DM,one OGTT is probably more reliable and adequate for establishing the diagnosis.Excessive weight and/or a positive family history of T2DM possibly affect the insulin and C-peptide response in the OGTT from a young age.

二甲双胍对IGT的干预治疗疗效观察

近年来糖尿病（ＤＭ）和糖耐量减低（ＩＧＴ）患病率有逐年增高的趋势，研究发现几乎所有的ＤＭ患者在发生ＤＭ之前，均经过ＩＧＴ阶段。本文通过对３２例ＩＧＴ者随机分为二甲双胍治疗组及非药物干预治疗组比较分析，结果提示，二甲双胍治疗组比非药物干预治疗组ＤＭ发生率明显减少，而ＩＧＴ向糖耐量正常（ＮＧＴ）人转化者则明显增多，这可能是二甲双胍具有不刺激胰岛β细胞分泌胰岛素，且能预防和减轻胰岛素抵抗，减轻高胰岛素血症之特点，进而能针对ＩＧＴ的基本缺陷——胰岛素抵抗和胰岛素分泌异常进行干预治疗，结果可纠正ＩＧＴ患者的糖代谢紊乱，防止ＩＧＴ向ＤＭ转化，同时又能使ＩＧＴ向糖耐量正常（ＮＧＴ）人转化。因此，用二甲双胍对ＩＧＴ的干预治疗对提高ＩＧＴ人群的生活质量，减少ＤＭ的发病率具有重要的意义。
