  • Cognitive impairment and dementia: a new emerging complication of type 2
           diabetes—The diabetologist’s perspective
    • Authors: Rafael Simó; Andreea Ciudin; Olga Simó-Servat; Cristina Hernández
      Pages: 417 - 424
      Abstract: Abstract Type 2 diabetes mellitus (T2D) and Alzheimer’s disease (AD) are two of the most common diseases of aging around the world. Given the frequency with which T2D and AD occur, the notion that people with T2D may be at increased risk for AD has large societal consequences, and understanding the mechanistic links between these diseases is imperative for the development of effective AD prevention and treatment strategies. Apart from being an accelerator of AD, T2D is associated with a progressive cognitive decline. Impaired insulin signaling, inflammation, the accumulation of advanced glycation end-products and oxidative stress all play an essential role in the pathogenesis of both AD and diabetic complications. Therefore, it is reasonable to postulate that these pathways are involved in the increased risk of dementia that occurs in the T2D population. The early diagnosis of cognitive impairment and the identification of the subset of patients at a higher risk of developing AD is a challenge for healthcare providers, and meeting it will permit us to implement a personalized medicine, which is an essential issue in diabetes care with significant therapeutic implications. The main gaps that should be filled to achieve this objective are examined.

  • Serum 1,5-anhydroglucitol level as a screening tool for diabetes mellitus
           in a community-based population at high risk of diabetes
    • Authors: Yao Wang; Yuexing Yuan; Yanli Zhang; Chenghao Lei; Yi Zhou; Jiajia He; Zilin Sun
      Pages: 425 - 431
      Abstract: Aims Early diagnosis of diabetes yields significant clinical benefits; however, currently available diagnostic tools for community-based population are limited. This study aimed to assess the value of serum 1,5-anhydroglucitol (1,5-AG) for the diagnosis and screening of diabetes mellitus in a community-based population at high risk of diabetes. Methods In this diagnostic test, 1170 participants underwent a 75-g oral glucose tolerance test. Venous blood samples were collected for fasting blood glucose (FBG), 2-h postprandial blood glucose (PBG), and glycosylated hemoglobin A1c (HbA1c) measurements. Serum 1,5-AG levels were detected by the GlycoMark assay, and a receiver operating characteristic (ROC) curve was generated to assess their diagnostic value for diabetes. Results A total of 298 adults were diagnosed with diabetes, indicating a prevalence of 25.47%. Partial Pearson correlation analysis adjusted for age and body mass index showed that serum 1,5-AG level was negatively correlated with FBG, PBG, and HbA1c (all P < 0.01). Areas under the curves (AUCs) for serum 1,5-AG, FBG, PBG, and HbA1c in identifying diabetes were 0.920, 0.874, 0.933, and 0.887, respectively. According to the ROC curve, the optimal cutoff value of serum 1,5-AG for diagnosing diabetes was 11.18 μg/ml, which yielded a sensitivity of 92.6% and a specificity of 82.3%, respectively. Comparisons between 1,5-AG and HbA1c showed that both the AUC and sensitivity of 1,5-AG were higher than those of HbA1c (both P < 0.01). Conclusions Serum 1,5-AG is a simple and effective marker with high sensitivity and specificity for identifying diabetes in populations at high risk of diabetes.

      Abstract: Aims Type 1 diabetes mellitus (T1DM) is characterized by severe autoimmune destruction of pancreatic beta-cells. The triggering of autoimmunity against beta-cells is probably caused by a combination of environmental and genetic risk factors. Even though much is known about the genetic of T1DM, more information is needed to completely unravel this tangled disease. MicroRNAs (miRNAs) are a class of small noncoding RNAs molecules that negatively regulate gene expression by inducing target mRNA cleavage or by inhibiting protein translation. Abnormal miRNA expressions have been described in autoimmune diseases and T1DM. Polymorphisms in genes codifying miRNAs may alter the expression of the corresponding miRNA and, thus, confer susceptibility for a given disease. Therefore, the aim of this study was to investigate whether polymorphisms in genes encoding miR-155, miR-146a, and miR-375 are associated with T1DM. Methods Frequencies of the miRNA-146a rs2910164, miRNA-155 rs767649 and miRNA-375 rs6715345 polymorphisms were analyzed in 490 T1DM patients and in 469 nondiabetic subjects. Results The miR-146a rs2910164 and miR-155 rs767649 polymorphisms were associated with protection for T1DM, and the strongest association was observed for the dominant model [odds ratio (OR) = 0.557 95% CI 0.355–0.874 and OR = 0.508, 95% CI 0.265–0.973, respectively, after adjustment for age, ethnicity, and risk HLA loci]. However, miR-375 rs6715345 frequencies did not differ between cases and controls. Conclusion MiR-146a rs2910164 and miR-155 rs767649 polymorphisms were associated with protection for T1DM.

      Abstract: Aims Lipoprotein (a) (Lp(a)), a well-established risk factor for coronary artery diseases (CAD), would also be anticipated to be associated in a similar manner with risk of type 2 diabetes mellitus (T2DM) based on the common soil hypothesis of etiology of T2DM and CAD. Unfortunately, there remains considerable uncertainty regarding the association of Lp(a) with the risk of T2DM. We aimed to examine the association of Lp(a) with T2DM. Methods Cross-sectional study of 1604 cases and 7983 controls was performed for identifying the association of Lp(a) with T2DM, its possible interactions with risk factors and threshold effects on T2DM. The association of Lp(a) with CAD was also examined and compared within the same study. Results On a continuous scale, 10 mg/L higher Lp(a) levels were insignificantly associated with a fully adjusted OR of 1.011, 95% CI 0.961–1.063 for T2DM. On a categorical scale, the fully adjusted ORs for T2DM were 0.733 (0.526–1.022), 0.554 (0.387–0.793), 0.848 (0.612–1.176), 0.727 (0.515–1.026), 0.692 (0.488–0.981), 0.696 (0.492–0.985), 0.719 (0.509–1.016), 0.74 (0.523–1.045), 0.809 (0.571–1.146), and 0.99 (0.962–1.019) for decile 2–10 in reference to decile 1. The magnitude of association did not increase with increasing decile (P for trend test = 0.990). In contrast, higher Lp(a) levels were significantly associated with prevalent CAD on a continuous or categorical scale in a fully adjusted model. No threshold effects were observed in terms of association of Lp(a) with T2DM or with CAD in Lp(a) <50 mg/dL. Conclusions The current study suggested that there was a lack of association of Lp(a) levels with prevalent T2DM. In contrast, Lp(a) levels were significantly associated with CAD in a dose-responding manner. Our findings provided evidence for differential approaches to higher Lp(a) levels in patients with T2DM or with CAD.

      Abstract: Aims Evidence of a role for type 2 diabetes in overall cancer risk and risk for specific types of cancer is limited in ethnic Chinese populations. We therefore investigated whether there is an association between diabetes and cancer incidence in Taiwan. Methods This study recruited a total of 3602 adults aged 35 years or over (average 54.9 ± 12.3 years, 52.8% women). Participants with fasting glucose ≥126 mg/dL, or taking hypoglycemic medications, were classed as having type 2 diabetes. Cancer incidence was established through regular follow-up interviews and medical records. Cox proportional hazard regression models were used to examine associations for diabetes with risk of all-cause and site-specific cancers. Results During a median of follow-up of 10.5 years, 275 individuals developed cancer, including 157 digestive cancers and 31 urinary cancers. Younger participants (aged < 55 years) with diabetes had a greater risk of all cancers [adjusted relative risk (RR) 3.42; 95% confidence interval (CI), 1.78–6.57], digestive cancers (adjusted RR 2.88; 95% CI 1.15–6.94) and urinary cancers (adjusted RR 13.4; 95% CI 2.70–66.3) compared with individuals in the same age group without diabetes. Conclusions Our results clearly demonstrate that middle-aged individuals of Chinese ethnicity with diabetes have a greater risk of all-cause cancer and specific subtypes of cancer.

  • Serum 1,5-anhydroglucitol levels slightly increase rather than decrease
           after a glucose load in subjects with different glucose tolerance status
    • Authors: Hang Su; Xiaojing Ma; Jun Yin; Yufei Wang; Xingxing He; Yuqian Bao; Jian Zhou; Weiping Jia
      Pages: 463 - 470
      Abstract: Aims Previous studies showed that serum 1,5-anhydroglucitol (1,5-AG) levels are significantly reduced in patients with diabetes mellitus (DM). However, it remains unclear how 1,5-AG levels acutely change in response to a glucose load. This study explored acute changes in 1,5-AG levels after a glucose load and the related influencing factors in individuals with differing degrees of glucose tolerance. Methods A total of 681 participants (353 without DM and 328 with DM) without a prior history of DM were enrolled. All participants underwent an oral glucose tolerance test. Fasting and postload (30, 60, 120, and 180 min) levels of plasma glucose, serum 1,5-AG, and insulin were measured. Results In all participant groups, serum 1,5-AG levels were slightly elevated after a glucose load and reached peak values at 120 min after loading (all P < 0.05). Regression analysis showed that body weight was negatively associated with the difference between peak and baseline 1,5-AG levels (Δ1,5-AG, standardized β = −0.119, P < 0.01). A strong and positive association between 1,5-AG0 and Δ1,5-AG was also found independent of other confounding factors (standardized β = 0.376, P < 0.01). The ratio of the Δ1,5-AG to the 1,5-AG0 was higher in DM patients (7.3% [3.4–11.5%]) than in those without DM (6.2% [3.6–9.2%]). Conclusions In contrast to the established decline in 1,5-AG levels with long-term hyperglycemia, the present study showed that serum 1,5-AG levels slightly increased by 6–7% after a glucose load. Further studies in different 1,5-AG transport models are needed to investigate the relevant metabolic pathways.

  • Diabetes-related burden and distress in people with diabetes mellitus at
           primary care level in Germany
    • Authors: N. Kuniss; T. Rechtacek; C. Kloos; U. A. Müller; J. Roth; K. Burghardt; G. Kramer
      Pages: 471 - 478
      Abstract: Aims The importance of diabetes-related distress for the treatment of diabetes is emphasised in national and international guidelines recommending routinely screening for psychosocial problems. Data of investigations regarding diabetes-related distress on primary care are rare in Germany though most people with diabetes are treated without insulin therapy at primary care level. Methods Three hundred and forty-five people with diabetes mellitus type 2 (DM2, n = 336, 229 without and 107 with insulin therapy) and type 1 (DM1, n = 9) were interviewed with the PAID questionnaire in the period from 1 October 2015 to 31 December 2015 in a general practice. A PAID score ≥40 (range 0–100) was considered as high diabetes-related distress. Results The mean PAID score of all participants was 3.9 ± 7.0 (DM2 without insulin 2.7 ± 6.3, DM2 with insulin therapy 6.0 ± 8.0, DM1 6.8 ± 4.9) and far below the threshold of 40 points. Only 1.2% of all responders showed high diabetes-related distress (score ≥40). People on insulin therapy with HbA1c >7.5% and with diagnosed depression prior to the study scored significantly higher. Furthermore, there are weak correlations between the PAID score and HbA1c (r = 0.253, p < 0.001), duration of diabetes (r = 0.169, p = 0.002), insulin dosage (r = 0.283, p < 0.001) and age (r = −0.129, p = 0.016). Conclusions Only 1.2% of our outpatients with diabetes on primary care level showed high diabetes-related distress. Higher rates in the current literature are probably due to not investigating on primary care level. Guidelines should consider this.

      Abstract: Aims Few data regarding prevalence of and risk factors for poor bone health in aging individuals with long-standing T1D are available. In this study, we aim to describe the prevalence of bone fragility and to identify factors associated with low bone density in individuals with long-term T1D. Methods We examined the prevalence of non-vertebral fractures in 985 subjects enrolled in the Joslin 50-Year Medalist Study and measured bone mineral density (BMD) by dual-energy X-ray absorptiometry at the femoral neck, lumbar spine and radius in a subset (65 subjects, mean age 62.6 years, duration 52.5 years, HbA1c 7.1%) with no significant clinical or demographic differences from the rest of the cohort. Results Medalists have low prevalence of fractures (0.20% hip and 0.91% wrist) and normal Z-score values (spine +1.15, total hip +0.23, femoral neck −0.01, radius +0.26; p > 0.05 for differences vs. 0 at all sites). A significant relationship was found between lower BMD and higher total cholesterol, triglycerides and LDL levels, but not HbA1c. Low BMD at the femoral neck was associated with cardiovascular disease after adjustment for confounding factors: prevalence risk ratio of CVD [95% CI] 4.6 [1.2–18.1], p = 0.03. No other diabetic vascular complication was found to be associated with low BMD. Conclusions These are the first data regarding bone health in aging individuals who have had diabetes for 50 or more years. The low rates of non-vertebral fractures and the normal Z-score suggest the long T1D diabetes duration did not increase the risk of bone fractures in Medalists compared to non-diabetic peers. Additionally, the association with cardiovascular disease demonstrates the BMD differences in groups are likely not due to glycemic control alone.

  • Retinal neurodegeneration in patients with type 1 diabetes mellitus: the
           role of glycemic variability

      Abstract: Aims Recent studies have identified neuroretinal abnormalities in persons affected by diabetes mellitus, before the onset of microvascular alterations. However, the role of glycemic variability (GV) on early retinal neurodegeneration is still not clarified. Methods To explore the relationship between glycemic control and neuroretinal characteristics, 37 persons with Type 1 diabetes mellitus (Type 1 DM) divided into two groups with no signs (noRD) and with mild non-proliferative diabetic retinopathy (NPDR) compared to 13 healthy control participants (C) were recruited. All persons underwent an optical coherence tomography with automatic segmentation of all neuroretinal layers. Measurements of mean of nasal (N)/temporal (T)/superior (S)/inferior (I) macular quadrants for individual layer were also calculated. Metabolic control was evaluated by glycated hemoglobin (HbA1c), and indexes of GV were calculated from continuous glucose monitoring. Results The difference among the three groups in terms of RNFL thickness was significantly dependent on quadrant (F(6;132) = 2.315; p = 0.037). This interaction was due to a specific difference in RNFL-N thickness, where both Type 1 DM groups showed a similar reduction versus C (−3.9 for noDR and −4.9 for NPDR), without any relevant difference between them (−1.0). Inner nuclear layer (INL) was increased in all quadrants in the two Type 1 DM groups compared to C (mean difference = 7.73; 95% CI: 0.32–15.14, p = 0.043; mean difference = 7.74; 95% CI: 0.33–15.15, p = 0.043, respectively). A negative correlation between RNFL-N and low blood glucose index (r = −0.382, p = 0.034) and positive correlation between INL and continuous overall net glycemic action −1, −2, −4 h (r = 0.40, p = 0.025; r = 0.39, p = 0.031; r = 0.41, p = 0.021, respectively) were observed in Type 1 DM patients. The triglycerides were positively and significantly correlated to INL (r = 0.48, p = 0.011), in Type 1 DM subjects. GV and triglycerides resulted both independent predictors of increased INL thickness. No correlation was found with HbA1c. Conclusions Early structural damage of neuroretina in persons with Type 1 DM patients is related to glucose fluctuations. GV should be addressed, even in the presence of a good metabolic control.

      Abstract: Aims The anti-inflammatory effects of the polyphenol resveratrol in patients with type 2 diabetes mellitus (T2DM) are controversial. Its role on pentraxin 3 (PTX3) concentrations, a human acute phase protein, has never been evaluated. Our aim was to determine whether a two-dosage resveratrol supplementation (500 and 40 mg/day) has an impact on PTX3 values in T2DM patients from a double-blind randomized placebo-controlled trial. Variations in total antioxidant status (TAS) were evaluated too. Methods A total of 192 T2DM patients were randomized to receive resveratrol 500 mg/day (Resv 500 arm), resveratrol 40 mg/day (Resv 40 arm) or placebo for 6 months. At baseline and at the trial end, PTX3 and TAS values were determined. Results A dose-dependent increase in PTX3 concentrations of 4.7% (Resv 40 arm) and 26.3% (Resv 500 arm), and 8.0% reduction after placebo were found. Adjusted mean differences of change versus placebo were 0.16 (95% CI 0.01–0.32) and 0.25 (0.09–0.42) in the Resv 40 and Resv 500 arms, respectively. At subgroup analyses, lower diabetes duration, aspirin, alcohol use, younger age, female gender, smoking (Resv 500 arm) and female gender and aspirin use (Resv 40 arm) were associated with higher PTX3 increments. A dose-dependent increment in TAS values in the resveratrol arms (1.4 and 6.4% for Resv 40 and Resv 500, respectively), and a reduction in placebo arm (−8.9%) were observed. Adjusted mean differences of change were 28.5 (95% CI 10.1–46.8) and 44.8 (25.4–64.1) in the Resv 40 and Resv 500 arms, respectively. Conclusion Resveratrol supplementation increased PTX3 and TAS levels in a dose-dependent manner in T2DM patients. At present, potential clinical implications of these results remain unclear.

  • Effects of GW002, a novel recombinant human glucagon-like peptide-1
           (GLP-1) analog fusion protein, on CHO recombinant cells and BKS-db mice
    • Abstract: Aims GLP-1-based strategies have many advantages in treatment of type 2 diabetes mellitus (T2DM), but native GLP-1 has a short half-life in the circulation, which limits its clinical application. The purpose of this study was to evaluate the effects of GW002, a novel recombinant GLP-1 analog fusion protein produced by linking the human GLP-1 analog C-terminus to the N-terminus of human serum albumin via a linker, in vitro and in BKS-db mice. Methods To determine whether GW002 can activate the GLP-1 receptor in cells, the level of luciferase expression was evaluated in vitro. In vivo, body weight, food intake, non-fasting and fasting blood glucose, oral glucose tolerance test, blood glucose and insulin levels, liver histology, liver function parameters and antibody levels in BKS-db mice were investigated to evaluate the effects of GW002. Albiglutide was chosen as a positive comparator. Results Cyclic adenosine monophosphate levels were increased in a dose-dependent manner in cells. In vivo studies demonstrated that GW002 lowers non-fasting and fasting blood glucose levels and improves glucose tolerance and insulin secretion in BKS-db mice. The degree of hepatic steatosis and hepatic biochemical indexes was also decreased. In this study, the mice body weight was not reduced significantly. Conclusions The above results showed that the efficacy of GW002 in BKS-db mice displayed a significant hypoglycemic effect, which indicated that GW002 might be a potential candidate for the treatment of T2DM.

  • Tailoring pharmacotherapy to specific eating behaviours in obesity: Can
           recommendations for personalised therapy be made from the current
           data'
    • Abstract: Abstract Pharmacotherapy provides an adjunct to behaviour modification in the management of obesity. There are a number of new drug therapies purportedly targeting appetite; liraglutide, and bupropion/naltrexone, which are European Medicines Agency and US Food and Drug Administration (FDA) approved, and lorcaserin and phentermine/topiramate, which have FDA approval only. Each of the six drugs, used singly or in combination, has distinct pharmacological, and presumably distinct behavioural, mechanisms of action, thus the potential to provide defined therapeutic options to personalise the management of obesity. Yet, with regard to pharmacotherapy for obesity, we are far from true personalised medicine. We review the limited mechanistic data with four mono and combination pharmacotherapies, to assess the potential for tailoring their use to target specific obesogenic behaviours. Potential treatment options are considered, but in the absence of adequate research in respect to effects of these drugs on eating behaviour, neural activity and psychological substrates that underlie poorly controlled eating, we are far from definitive therapeutic recommendations. Specific mechanistic studies and broader behavioural phenotyping, possibly in conjunction with pharmacogenetic research, are required to characterise responders for distinct pharmacotherapeutic options.

  • Effect of statins on hospitalization risk of bacterial infections in
           patients with or without diabetes
    • Abstract: Aims To investigate whether statins reduce the risk to first hospitalization of bacterial infections, in patients with or without diabetes taking into account prior or incident comorbidities. Methods By using administrative databases, the effect of current statin use was measured on the risk of first hospitalizations due to bacterial infections in people living in Tuscany, Italy, in the period January 1, 2011–December 31, 2015, after excluding those with previous statins use. Population was stratified as with (n = 128,207) or without diabetes (n = 3,304,906), and the hospitalization risk was analyzed by a Cox proportional hazards regression analysis after adjusting for age, gender, previous comorbidities, chronic renal failure, and prior or incident cardiovascular diseases. Results During the 5-year follow-up, 31,543 hospitalizations for bacterial infections were observed: 2.08(2.06–2.10) per 1000 person-year in non-diabetic and 5679: 9.13(8.94–9.32) per 1000 person-year in diabetic population. Diabetes conferred a greater risk of hospitalizations, independently from confounders [adjusted HR (95% CI) 2.04 (1.97–2.10); P < 0.0001]. Statin use decreased the risk by about 2.5% for each one month of therapy, at the same extent in subjects with or without diabetes, after adjusting for all covariates. Conclusions In this population, diabetes was associated by a twofold increase in the 5-year risk of hospitalizations for bacterial infections. Statin use decreased this risk to a same extent in subjects without or with diabetes, after adjusting for main confounders including comorbidities, and previous or incident cardiovascular events.

  • Glucose-independent association of adiposity and diet composition with
           cardiovascular risk in children and adolescents with type 1 diabetes
    • Abstract: Aims To test the hypothesis that diet composition, adiposity and glycometabolic control could independently contribute to an increase in the cardiovascular risk (CVR) for children/adolescents with type 1 diabetes (T1D). Methods One hundred and eighty children/adolescents with T1D (age range 5–18 years) were enrolled. Diet (3-day weighed dietary record), physical (height, weight, waist circumference, bioelectrical impedance analysis) and biochemical (HbA1c, lipid profile) parameters were recorded. Regression models, using non-HDL cholesterol (a gross index of CVR) as the dependent variable and HbA1c (mmol/mol), fat mass (FM) %, lipid-to-carbohydrate intake ratio as independent ones, were calculated. Results Non-HDL cholesterol was significantly associated with adiposity (FM%; r = 0.27, 95% CI 0.13–0.43), body fat distribution (waist-to-height ratio; r = 0.16, 95% CI 0.02–0.31), lipid intake [% of energy intake (EI)] (r = 0.25, 95% CI 0.11–0.41), carbohydrate intake (% EI; r = −0.24, 95% CI 0.10–0.40), lipid-to-carbohydrate intake ratio (r = 0.26, 95% CI 0.12–0.42) and blood glucose control (HbA1c; r = 0.24, 95% CI 0.10–0.40). A p value cutoff of 0.10 was used for covariates to be included in the regression analysis. Multiple regression analysis showed that adiposity (FM%), blood glucose control (HbA1c) and lipid-to-carbohydrate intake ratio independently contributed to explaining the inter-individual variability of non-HDL cholesterol (R 2 = 0.163, p < 0.05). Conclusions Adiposity and lipid-to-carbohydrate intake ratio affect non-HDL cholesterol, a gross index of CVR, regardless of HbA1c, in children and adolescents with T1D. Intervention to reduce CVR in T1D patients should focus not only on glycometabolic control but also on adiposity and diet composition.

  • Achievement of metabolic control among children and adolescents with type
           1 diabetes in Spain
    • Abstract: Aims To assess metabolic control in a paediatric T1D population in Spain and analyse the rate of severe acute decompensations and chronic complications. Methods Data from patients treated at eight paediatric diabetes units with experienced diabetes teams between June and December 2014 were analysed in an observational prospective study. Variables included: age, sex, diabetes duration, number of follow-up visits/year, anthropometrical data, insulin treatment modalities, mean annual HbA1c and the prevalence of acute and chronic complications. SPSS statistics 21.0 was used. Results A total of 853 patients (49.7% female) with a mean age of 12.1 ± 3.7 years were included. Anthropometric data were normal. Mean diabetes duration was 8 ± 3.4 years. Mean outpatient follow-up was 4.7 ± 0.04 visits/year. Twenty-five per cent were on continuous subcutaneous insulin infusion (CSII). Mean HbA1c was 7.3 ± 1% (56 ± 8 mmol/mol) and 66.6% had HbA1c < 7.5% (58 mmol/mol). HbA1c value correlated negatively with age at onset and positively with years of diabetes, number of visits/year and current age (F = 7.06; p = 0.01). Patients on CSII (n = 213) were younger, attended the outpatient clinic more frequently, were diagnosed earlier, had better metabolic control and had presented more severe hypoglycaemic episodes the previous year. The rate of severe decompensation (episodes/100 patients/year) was ketoacidosis 1.5 and severe hypoglycaemia 4.5. The prevalence of chronic complications was very low. Conclusions Our data describe the good compliance of paediatric T1D patients treated at eight paediatric units in Spain following international standards of metabolic control.

  • Toward molecular imaging of the free fatty acid receptor 1
    • Abstract: Aims Molecular imaging of the free fatty acid receptor 1 (FFAR1) would be a valuable tool for drug development by enabling in vivo target engagement studies in human. It has also been suggested as a putative target for beta cell imaging, but the inherent lipophilicity of most FFAR1 binders produces high off-target binding, which has hampered progress in this area. The aim of this study was to generate a suitable lead compound for further PET labeling. Methods In order to identify a lead compound for future PET labeling for quantitative imaging of FFAR1 in human, we evaluated tritiated small molecule FFAR1 binding probes ([3H]AZ1, [3H]AZ2 and [3H]TAK-875) for their off-target binding, receptor density and affinity in human pancreatic tissue (islets and exocrine) and rodent insulinoma. Results [3H]AZ1 showed improved specificity to FFAR1, with decreased off-target binding compared to [3H]AZ2 and [3H]TAK-875, while retaining high affinity in the nanomolar range. FFAR1 density in human islets was approximately 50% higher than in exocrine tissue. Conclusions AZ1 is a suitable lead compound for PET labeling for molecular imaging of FFAR1 in humans, due to high affinity and reduced off-target binding.

      Abstract: Aims To evaluate the association of 64 obesity-related polymorphisms with pediatric-onset type 2 diabetes and other glucose- and insulin-related traits in Mexican children. Methods Case–control and case–sibling designs were followed. We studied 99 patients with pediatric-onset type 2 diabetes, their siblings (n = 101) without diabetes, 83 unrelated pediatric controls and 137 adult controls. Genotypes were determined for 64 single nucleotide polymorphisms, and a possible association was examined between those genotypes and type 2 diabetes and other quantitative traits, after adjusting for age, sex and body mass index. Results In the case–pediatric control and case–adult control analyses, five polymorphisms were associated with increased likelihood of pediatric-onset type 2 diabetes; only one of these polymorphisms (CADM2/rs1307880) also showed a consistent effect in the case–sibling analysis. The associations in the combined analysis were as follows: ADORA1/rs903361 (OR 1.9, 95% CI 1.2; 3.0); CADM2/rs13078807 (OR 2.2, 95% CI 1.2; 4.0); GNPDA2/rs10938397 (OR 2.2, 95% CI 1.4; 3.7); VEGFA/rs6905288 (OR 1.4, 95% CI 1.1; 2.1) and FTO/rs9939609 (OR 1.8, 95% CI 1.0; 3.2). We also identified 16 polymorphisms nominally associated with quantitative traits in participants without diabetes. Conclusions ADORA/rs903361, CADM2/rs13078807, GNPDA2/rs10938397, VEGFA/rs6905288 and FTO/rs9939609 are associated with an increased risk of pediatric-onset type 2 diabetes in the Mexican population.

  • Early screening for type 2 diabetes following gestational diabetes
           mellitus in France: hardly any impact of the 2010 guidelines
    • Authors: K. Goueslard; J. Cottenet; A.-S. Mariet; P. Sagot; J.-M. Petit; C. Quantin
      Abstract: Aims Women who had gestational diabetes mellitus (GDM) have a high risk of type 2 diabetes mellitus (T2DM) in the years following pregnancy. Most follow-up screening studies have been conducted in limited geographical areas leading to large variability in the results. The aim of our investigation was to measure how the publication of guidelines affected early screening for T2DM after a pregnancy with GDM during the period 2007–2013, in France. Methods We conducted a retrospective cohort study in a representative sample of 1/97th of the French population using data from the “National Health Insurance Inter-Regime Information System,” which collects individual hospital and non-hospital data for healthcare consumption. Results The sample included 49,080 women who gave birth in 2007–2013. In the following 3 months, only 18.49% of women with GDM had an oral glucose tolerance test or a blood glucose test in 2007. This rate had not significantly increased in 2013 (p = 0.18). The proportion of women with GDM who had the recommended glycemic follow-up at 3 months (20.30 vs. 21.58%, p = 0.19) and 6 months (32.48 vs. 37.16%, p = 0.08) was not significantly different before the guidelines (2008–2009) and after the guidelines (2012–2013). At 12 months, the difference was significant (46.77 vs. 54.05%, p = 0.009). Conclusion Postpartum screening has improved only slightly since the guidelines and remains largely insufficient, with less than 25% of women with GDM screened in the first 3 months. In the first year after delivery, less than 60% of women were screened for T2DM.
